Technical Field

The invention relates to a reeling pet toilet.

Background

Conventionally, in the case of disposing of excrement of pets such as dogs and cats for indoor use, a predetermined container (toilet stool) in which a disposal mat such as newspaper or cloth is laid in advance has been used.

The owner trains the pet to discharge the pet into the container (toilet stool) to prevent the floor from being contaminated, and when the excrement such as the feces and the urine is discharged into the container (toilet stool), the excrement is collected together with the disposal pad and discarded, and then the disposal pad is replaced with a new disposal pad.

However, for the owner, there are the following problems: such work is unhygienic and labor intensive.

In order to solve such a problem, patent document 1 describes a pet litter box capable of efficiently and hygienically disposing of feces and urine after excretion of a pet, and a disposal pad used for the pet litter box.

Patent document 2 describes a pet litter box that can easily perform a task of replenishing a disposal pad and can be continuously used by replenishing a new disposal pad even in a state where the disposal pad remains.

Disclosure of Invention

Problems to be solved by the invention

However, the pet litter box disclosed in patent document 1 has a structure in which the disposal mat is manually pulled out, and therefore has the following problems: for example, when the owner is not at home, the disposal pad after excretion cannot be replaced, and the offensive odor is emitted regardless of the feces and urine on the disposal pad for a long time.

In addition, since the pet litter box described in patent document 2 is wound and collected in a state where the litter is squashed between the disposal mats, the litter may not be squashed depending on the hardness of the litter, and the disposal mats may be broken. Further, since feces and urine are collected while being wound around one place, the weight of the used disposal pad is likely to increase, and not only the labor for replacement is increased, but also a strong offensive odor may be generated.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a pet litter box that can be easily replaced while preventing breakage of a disposal mat, and that can be comfortably used by a pet owner.

Means for solving the problems

In order to solve the above problem, the present invention is characterized by comprising:

a belt-shaped disposal pad for disposing of excrement of pets; a take-up roller that takes up the treatment pad; a pedestal on which the treatment pad is laid; an excrement recovery unit that recovers the excrement;

the excrement recovery part is provided with a winding roller for recovering urine and a excrement recovery part for recovering excrement.

According to the present invention, since the feces is collected in the feces collection portion without being wound around the take-up roll, the breakage of the treatment pad can be suppressed. In addition, the weight of the used treatment pad is not easily increased, so that the treatment pad can be easily replaced. Further, since feces and urine are separately collected, the generation of malodor can be suppressed.

In a preferred aspect of the present invention, a squeegee is provided in the feces collection portion so as to contact the processing pad in the width direction.

With this configuration, even if the feces has a large moisture content and is adsorbed on the treatment pad, for example, the feces can be peeled off from the treatment pad without touching the feces with hands and can be stored in the feces collection unit.

In a preferred aspect of the present invention, the feces collection portion is substantially transparent.

With this configuration, whether or not there is feces inside the feces collection portion can be easily visually recognized from the outside.

In a preferred aspect of the present invention, the winding-out roller and the winding-up roller are housed in a housing in the same space.

With such a configuration, the entire pet litter box can be made compact, and the ease of use and the degree of freedom of the installation position can be improved.

In a preferred aspect of the present invention, the frame body has a side wall portion that is substantially parallel to the width direction of the processing pad and stands substantially perpendicular to the pedestal, and an insertion opening into which the processing pad is inserted is provided above the side wall portion.

With this configuration, the processing pad can be attached so as to cover the side wall portion. Thus, urine of a pet having a habit of scattering urine toward a wall can be stopped and recovered by the disposal pad.

In a preferred aspect of the present invention, the housing has an opening for allowing the unwinding roller and the winding roller to move in and out.

With such a configuration, the treatment pad can be quickly replaced by a simple operation.

In a preferred aspect of the present invention, the base is attachable to and detachable from the side wall portion.

With this configuration, the treatment pad can be easily attached to the pedestal and cleaned.

In a preferred aspect of the present invention, the pedestal further includes a pressure-sensitive sensor for sensing the presence or absence of excrement based on the weight of the pedestal.

With such a configuration, even when the pet is not present in the owner for a long time, the excrement can be automatically collected in the excrement collection unit.

In a preferred aspect of the present invention, the processing device further includes a reading sensor that reads a length of the processing mat wound around the winding roller.

By adopting such a structure, waste of the disposal pad can be prevented.

In a preferred aspect of the present invention, the apparatus further includes a notification unit configured to notify a replacement timing of the treatment pad.

With this configuration, the user can immediately visually recognize whether the pad needs to be replaced without confirming the state of the pad.

In a preferred aspect of the present invention, the feces collection portion is provided with a medicine storage portion.

With such a configuration, the interior of the feces collection portion can be kept odorless and clean.

Effects of the invention

According to the present invention, it is possible to provide a pet litter box that can be easily replaced while preventing breakage of a mat, and that can be comfortably used by a pet owner.

Detailed Description

Hereinafter, a pet litter box according to an embodiment of the present invention will be described with reference to fig. 1 to 10. The embodiment described below is an example of the present invention, and the present invention is not limited to the embodiment described below.

As shown in fig. 1, the pet litter box according to the embodiment of the present invention includes a disposal mat 1, a substantially rectangular plate-shaped pedestal 2 on which the disposal mat 1 is laid, a center frame 3 of the mounting pedestal 2, a substantially rectangular box-shaped frame body 4 in which the disposal mat 1 is housed, a litter collection unit 5, a front frame 6 on which the litter collection unit 5 is mounted, a motor unit 7, a reading sensor 8, a light emitter 9, a control unit 10, and a base 11.

As the material of the processing pad 1, a material having water absorption property such as a paper material is preferably used.

As the material of the pedestal 2, the frame 4, and the base 11, wood is preferably used, but various materials such as metal and synthetic resin can be applied.

As the material of the center frame 3 and the front frame 6, metal or synthetic resin is preferably used.

As a material of the feces collection portion 5, a synthetic resin is preferably used.

In order to clarify the boundary between the processing pad 1 and the pedestal 2, the processing pad 1 is virtually cut off by a one-dot chain line on the upper surface of the pedestal 2.

For convenience of explanation, the line a-a shown in fig. 1 is referred to as a front-rear direction, and a direction orthogonal to the front-rear direction in a plane parallel to the base 11 is referred to as a left-right direction. In the front-rear direction, the feces collection portion 5 side is referred to as the front, the frame 4 side is referred to as the rear, the side in the left-right direction on which the motor portion 7, the reading sensor 8, the light emitter 9, and the control portion 10 are provided is referred to as the left, and the side opposite to the left is referred to as the right.

A pair of locking holes H are provided on the upper surface of the pedestal 2 at intervals in the left-right direction so as not to overlap with the processing pad 1. The frame body 4 has a side wall portion 4a that is substantially parallel to the width direction of the treatment pad 1 and stands substantially perpendicular to the pedestal 2, and a pair of locking projections P that are inserted into the locking holes H are provided above the side wall portion 4a at a distance in the left-right direction.

With such a configuration, the pedestal 2 can be locked to the frame 4 in a state substantially perpendicular to the base 11 by the pair of locking holes H and the pair of locking projections P by rotating the pedestal 2 with the rear short side as the axial direction toward the frame 4.

The center frame 3 includes a base 3a (see fig. 3) and upright portions 3b erected on both left and right ends of the base 3 a.

The motor unit 7 includes a first motor 7a for opening and closing the waste collection unit 5 and a second motor 7b for winding and unwinding the processing mat 1.

The motor unit 7, the reading sensor 8, and the light emitter 9 are electrically connected to the control unit 10 via a connection cable C.

The connection cable C connected to the first motor 7a is inserted into a through hole T penetrating the upright portion 3b and the front side surface of the housing 4 in the front-rear direction, and is drawn out to the vicinity of the left side surface of the housing 4, thereby being connected to the control unit 10.

As shown in fig. 2, the frame 4 has a side wall portion 4a, an opening 4b formed in an upper surface, and an opening 4c formed in a side surface opposite to the side wall portion 4 a.

The side wall portion 4a is provided with an upper insertion opening 4a1 into which the processing pad 1 is inserted and a lower insertion opening 4a 2.

Inside the housing 4, a take-up roll R1 around which the pre-used treatment mat 1 is wound and a take-up roll R2 around which the post-used treatment mat is wound are provided. Further, a first elongated cylindrical auxiliary roller r1 and a second elongated cylindrical auxiliary roller r2 for maintaining the tension of the processing mat 1 appropriately and performing the winding operation smoothly are rotatably provided in the vicinity of the lower insertion port 4a2 by a pair of first brackets B1.

Fig. 3 is a plan view of the pet litter box of the present embodiment in which the pedestal 2 and the frame 4 are locked to each other by the locking hole H and the locking protrusion P. For convenience of explanation, the processing mat 1, the unwinding roller R1, and the winding roller R2 are omitted.

As shown in fig. 3, the center frame 3 is provided with pressure-sensitive sensors S at four corners on the upper surface of the base portion 3a, and each pressure-sensitive sensor S is electrically connected to the control portion 10 via a connection cable C.

The connection cable C connected to each pressure sensor S is provided on the inner surface of the left standing portion 3b, inserted into a small hole (not shown) communicating with the through hole T, and pulled out to the vicinity of the left side surface of the housing 4, thereby being connected to the control unit 10.

Each pressure sensor S senses the movement of the upper and lower bases 2 for pets such as dogs and cats.

Specifically, each of the pressure-sensitive sensors S is configured to: when a predetermined time elapses from the moment when a predetermined weight is sensed to be loaded on the pedestal 2 (the moment when a pet gets on the pedestal 2), and the moment when the weight is unloaded (the moment when the pet gets off the pedestal 2) is sensed, a signal is transmitted to the control unit 10.

Since each pressure sensor S transmits a signal when sensing the moment when the weight is unloaded, it does not transmit a signal when a pet sleeps on the upper surface of the pedestal 2, for example. By setting the predetermined time to, for example, about several tens of seconds, it is possible to configure not to transmit a signal when the pet has passed the upper surface of the pedestal 2 only for a short time.

A third auxiliary roller r3 having an elongated cylindrical shape for performing a winding operation smoothly is rotatably provided on one short-side end surface of the base 2 via a pair of second brackets B2.

At the left end of the second auxiliary roller r2, a plurality of reading marks M are provided at regular intervals over the entire circumference of the second auxiliary roller r 2. The reading sensor 8 is provided to protrude from the outside of the left side surface of the housing 4 toward the inside of the left side surface, and the reading unit 8a is configured to face the left end of the second auxiliary roller r 2.

With this configuration, the reading sensor 8 can read the reading mark M provided at the left end of the second auxiliary roller r2 and read the length of the processing pad 1 pulled out by the reading unit 8 a.

Fig. 4(a) is a schematic perspective view of the feces collection portion 5 viewed from the left rear side, and fig. 4(b) is a schematic perspective view of the feces collection portion 5 and the front frame 6 viewed from the right front side.

As shown in fig. 4(a) and 4(b), the feces collection portion 5 includes a main body portion 5a, a gate portion 5b, a scraper 5c for separating the feces D excreted into the disposal pad 1 from the disposal pad 1, and a collection tray 5D.

In fig. 4(a), the recovery tray 5d is omitted for convenience of explanation.

The main body 5a is formed to be substantially transparent as a whole. Further, a pair of locking holes 5a1 for holding a placement position facing the front frame 6, particularly for preventing movement in the front-rear direction, are provided on the bottom surface at a distance in the left-right direction. Further, a pair of projections 5a2 for holding the placement position facing the front frame 6, and particularly for preventing the vertical movement, are provided on both the left and right side surfaces. Further, an opening portion 5a3 into which the recovery tray 5d is inserted is provided at the front.

The door 5b is formed to be substantially transparent as a whole and is provided on both left and right sides of the body 5 a. The gear G2 is engaged with the left side surface of the door 5b via the left side surface of the body 5a, and the gear G2 meshes with a gear G1 attached to a first motor 7a described later.

The scrapers 5c are provided on lower portions of both left and right side surfaces of the body 5 a.

The collection tray 5d is provided with a hand-held portion 5d1 for easily moving in and out of the main body portion 5 a.

The front frame 6 has a base 6a, and standing portions 6b standing on both left and right ends of the base 6 a.

A pair of locking tongues 6a1 locked in the pair of locking holes 5a1 are provided on the upper surface of the base 6a at a distance in the left-right direction.

A pair of locking grooves 6b2 into which the pair of projections 5a2 are fitted are provided on opposite side surfaces of the standing portion 6 b. Further, in the left standing portion 6b, a gear G1 attached to the first motor 7a is exposed at a side surface where the locking groove 6b2 is provided. In addition, the gear G1 rotates in synchronization with the rotation of the first motor 7 a.

With such a configuration, the rotation of the first motor 7a is transmitted to the door 5b via the gear G1 and the gear G2, and the door 5b is opened and closed in synchronization with the rotation of the first motor 7 a.

As shown in fig. 4(b), the collection tray 5d is configured to: by being inserted into the opening portion 5a3, the body portion 5a is attached to be drawable (see arrow a). Further, the feces collection portion 5 is slid so that the pair of protrusions 5a2 are fitted into the pair of locking grooves 6b2, the gear G1 meshes with the gear G2, and the pair of locking tongues 6a1 are locked to the pair of locking holes 5a1 (see arrow b). Thus, the placement position of the feces collection section 5 facing the front frame 6 is held.

In the state where the placement position is held, the collection tray 5d is detached from the feces collection portion 5, the pair of locking tongues 6a1 are pushed down, and the main body portion 5a is slid forward, whereby the feces collection portion 5 can be easily detached from the front frame 6. This makes it possible to easily clean the feces collection portion 5.

As described above, the feces collection portion 5 and the front frame 6 are assembled in the state shown in fig. 1. The squeegee 5c is in contact with the processing pad 1 in the width direction (see fig. 8 and 9).

Fig. 5 is an exploded perspective view of the unwinding roller R1 around which the processing mat 1 is wound and the winding roller R2 before the processing mat 1 is wound, as viewed from the front left.

As shown in fig. 5(a), the unwinding roller R1 includes a cylindrical body R11 and a pair of substantially disk-shaped covers R12 attached to both ends of the cylindrical body R11.

The pair of covers R12 are provided with cylindrical projections R12a to be placed on a pair of supporting members S1 described later. Further, a gear G4 is engaged with the left cover R22 on a shaft substantially identical to the cylindrical protrusion R22a, and the gear G4 is configured to mesh with a gear G3 attached to a second motor 7b described later.

As shown in fig. 5(b), the take-up roll R2 includes a tubular body R21 and a pair of substantially disk-shaped covers R22 attached to both ends of the tubular body R21, similarly to the take-up roll R1.

Similarly to the unwinding roller R1, the pair of covers R22 are provided with cylindrical projections R22a mounted on a pair of support members S2 described later, and a gear G4 is engaged with the left cover R22 on a shaft substantially identical to the cylindrical projections R22a, and the gear G4 is configured to mesh with a gear G3 attached to a second motor 7b described later.

Fig. 6 is a schematic perspective view of the pedestal 2 and the housing 4 as viewed from the front right.

For convenience of explanation, the right side surface of the housing is virtually cut off by a one-dot chain line.

As shown in fig. 6(a), a pair of support members S1 and S2 (the support members S1 and S2 provided on the inner side of the right side surface are indicated by broken lines) for supporting the unwinding roller R1 and the winding roller R2 are provided on the inner sides of the left and right side surfaces of the housing 4.

Specifically, the pair of support members S1 and S2 have mounting grooves S1a and S2a formed therein, and the winding-out roller R1 and the winding-up roller R2 are rotatably supported by placing the cylindrical projections R12a and R22a of the winding-out roller R1 and the winding-up roller R2 in the mounting grooves S1a and S2 a.

In the pair of support members S2, the gear G3 engaged with the second motor 7b is exposed in the support member S2 provided on the left side surface. In addition, the gear G3 rotates in synchronization with the rotation of the second motor 7 b.

With such a configuration, the rotation of the second motor 7b is transmitted to the take-up roller R2 via the gear G3 and the gear G4, and the take-up operation of the processing mat 1 is performed in synchronization with the rotation of the second motor 7 b.

In fig. 6(a), the unwinding roller R1 around which the processing mat 1 is wound is inserted into the opening 4b of the housing 4, and placed on the pair of support members S1 (see arrow c), and the winding roller R2 is inserted into the opening 4c of the housing 4, and placed on the pair of support members S2 (see arrow d) so that the gear G3 and the gear G4 mesh with each other, and the state shown in fig. 6(b) is achieved.

Hereinafter, the procedure of mounting the disposal pad 1 to the pet litter box of the present embodiment will be described with reference to fig. 7.

Fig. 7 is a sectional view taken along line a-a of the pet litter box of the embodiment.

First, as shown by a broken line in fig. 7(a), the processing mat 1 wound around the windup roller R1 is inserted into the upper insertion port 4a1, pulled out downward so as to cover the front side surface of the frame 4, and then inserted into the lower insertion port 4a 2. Next, the processing pad 1 pulled out in this manner is locked to the first auxiliary roller r1 and inserted into the lower insertion opening 4a2 again.

After the mounting shown by the broken line in fig. 7(a) is completed, the base 2 is locked to the housing 4 by using the locking hole H and the locking projection P.

Next, as shown by the broken line in fig. 7(b), the treatment pad 1 is pulled out so as to cover the pedestal 2 from above, and then inserted into the lower insertion port 4a2 from below the pedestal 2. Next, the thus-pulled processing mat 1 is pulled out so as to pass between the second auxiliary roller R2 and the bottom surface of the frame 4, and is bonded to the take-up roller R2.

As described above, after the treatment pad 1 is attached, the pedestal 2 is detached from the frame 4 and is mounted on the center frame 3 again, and the state shown in fig. 1 is obtained.

In the state shown in fig. 1, the rotational axes of the unwinding roller R1, the winding roller R2, the first auxiliary roller R1, the second auxiliary roller R2, and the third auxiliary roller R3 are all parallel to each other.

Hereinafter, a method of using the pet litter box of the present embodiment will be described with reference to fig. 8 and 9.

Fig. 8 and 9 are cross-sectional views of the pet litter box of the present embodiment as viewed from the right, taken along the front-rear direction.

First, the pet (not shown) performs a series of operations as follows: the urine is discharged from the bed 2 (fig. 8 a) after the urine is discharged from the feces D and urine onto the bed 2 on which the treatment pad 1 is laid. The pressure sensor S receives this operation, and sends a signal to start the rotation operation of the take-up roller R2 and a signal to turn on the feces collection unit 5 to the control unit 10.

Accordingly, the take-up roll R2 is rotated rearward by the second motor 7b, and the waste D and urine (not shown) are moved forward by the processing mat 1 being taken up by the take-up roll R2. Further, the gate 5b is rotated forward by the first motor 7a while the take-up roll R2 is rotated, and the feces collection section 5 is opened. Therefore, the feces D moved to the front side finally falls down on the collection tray 5D (the state of fig. 8 (b)). At this time, even when the amount of moisture of the feces D is large and the feces D is adsorbed on the treatment pad 1, the feces D is peeled off from the treatment pad 1 by the scraper 5c and dropped on the collection tray 5D.

Further, the take-up roll R2 is rotated, and urine (not shown) that has penetrated into the treatment pad 1 passes through the bottom surface of the pedestal 2, and is wound around the take-up roll R2 and collected.

Next, when the reading sensor 8 detects that the processing pad 1 is wound around the winding roll R2 by a predetermined length via the reading mark M, a signal for stopping the rotation operation of the winding roll R2 and a signal for turning off the waste collection unit 5 are transmitted to the control unit 10.

Thereby, the rotation of the second motor 7b is stopped, and the rotation operation of the take-up roller R2 is stopped. Further, the door portion 5b is rotated rearward by the first motor 7a, and the feces collection portion 5 is closed (the state of fig. 9 (a)).

By repeating the above-described series of operations, the feces D is retained in the feces collection portion 5. Therefore, the owner appropriately pulls out the collection tray 5D from the main body 5a to dispose the feces D, thereby emptying the inside of the feces collection portion 5.

Further, by repeating the above-described series of operations, most of the processing mat 1 wound around the unwinding roller R1 is wound around the winding roller R2. At this time, the reading sensor 8 reads the total length of the processing mat 1 wound around the winding roller R2 through the reading mark M, and reads the state immediately before the processing mat 1 is used up. Then, the reading sensor 8 that has read this state transmits a signal for turning on the light emitting body 9 to the control unit 10.

Thereby, the light emitter 9 is turned on, and the owner is notified that the treatment pad 1 needs to be replaced (the state of fig. 9 (b)).

The pad 1 is replaced in the following order.

First, the used treatment pad 1 is cut at an arbitrary position such as the upper surface of the pedestal 2, and the cut portion of the used treatment pad 1 is removed from the take-up roll R1. By doing so, the used treatment pad 1 is completely unwound from the unwinding roll R1.

Next, the take-up roller R2 around which the used treatment pad 1 is wound is taken out to the outside through the open mouth 4c, and after the pair of covers R22 are removed and discarded, the take-up roller R1 is placed on the pair of support members S2 so that the gear G3 and the gear G4 mesh with each other.

Next, the pair of covers R22 are attached to the other unwinding roller R1 around which the pre-use treatment pad 1 is wound, and after being placed on the pair of support members S1 through the open mouth 4b, one end edge of the cut portion is connected to the leading end edge of the pre-use treatment pad 1 by an adhesive method such as tape.

Next, the pre-use treatment pad 1 is attached to the pedestal 2 in the order shown in fig. 7, and the other end edge of the cut portion connected to the pre-use treatment pad 1 is connected to the take-up roller R1 mounted on the pair of support members S2 by means of an adhesive such as tape.

By doing so, the treatment pad 1 is replaced, and the state shown in fig. 1 can be achieved again.

According to the present embodiment, the excrement collection unit for collecting excrement includes the take-up roll R2 for collecting urine (not shown) and the excrement collection unit 5 for collecting excrement D, and the excrement D is collected into the excrement collection unit 5 without being wound around the take-up roll R2, so that breakage of the disposal pad 1 can be suppressed. In addition, since the weight of the used treatment pad 1 is not easily increased, the treatment pad 1 can be easily replaced. Since the feces D and urine (not shown) are collected separately, the generation of malodor can be suppressed.

Further, since the feces collection portion 5 has the scraper 5c contacting the treatment pad 1 in the width direction, even if the feces D has a large amount of moisture and is adsorbed on the treatment pad 1, for example, it can be peeled off from the treatment pad 1 without touching it with hands and stored in the feces collection portion 5.

Further, since the feces collection portion 5 is substantially transparent, whether or not the feces D is present inside the feces collection portion 5 can be easily visually recognized from the outside.

Further, by providing the frame 4 that accommodates the unwinding roller R1 and the winding roller R2 in the same space, the pet toilet of the present embodiment can be made compact as a whole, and the ease of use and the degree of freedom of the installation position can be improved.

The frame 4 has a side wall portion 4a that is substantially parallel to the width direction of the processing pad 1 and is erected substantially perpendicularly to the pedestal 2, and an upper insertion opening 4a1 into which the processing pad 1 is inserted is provided above the side wall portion 4a, whereby the processing pad 1 can be attached so as to cover the side wall portion 4 a. Thus, the disposal pad 1 can be used to block and collect urine from pets having a habit of urinating toward the wall.

Further, by forming the openings 4b and 4c for the feeding and discharging of the unwinding roller R1 and the winding roller R2 in the frame 4, the treatment pad 1 can be quickly replaced by a simple operation.

Further, the pedestal 2 is attachable to and detachable from the side wall portion 4a, whereby the treatment pad 1 can be easily attached to the pedestal 2 and the pedestal 2 can be easily cleaned.

Further, by providing the pressure-sensitive sensor S for sensing the presence or absence of excrement based on the weight of the pedestal 2, even when the pet is not present for a long time such as when the owner is not at home, excrement can be automatically collected into the take-up roll R2 and the excrement collecting section 5.

Further, by providing the reading sensor 8 for reading the length of the processing pad 1 wound around the winding roller R2 on the left side surface of the housing 4, waste of the processing pad 1 can be prevented.

Further, the light emitter 9 is provided as a notification unit for notifying the replacement timing of the treatment pad 1, so that the owner can immediately visually recognize whether or not the replacement is necessary without confirming the state of the treatment pad 1.

The shapes, dimensions, and the like of the respective structural members shown in the above embodiments are examples, and various modifications can be made based on design requirements and the like.

For example, as shown in fig. 10(a), the medicine storage portions Z may be provided at both ends in the left-right direction in the feces collection portion 5.

The medicine storage portion Z is fixed to the bottom surface of the feces collection portion 5, and as shown in fig. 10(b), the medicine storage portion Z has a substantially rectangular parallelepiped shape, and the deodorant storage portion main body Z1 is hinge-coupled to the lid portion Z2 so as to be openable and closable.

Thus, the owner can store the chemicals necessary for the deodorant, the bactericide, the antibacterial agent, and the like in the chemical storage portion main body Z1 in advance, and can keep the inside of the feces collection portion 5 odorless and clean.

The medicine storage portion Z is not necessarily provided inside the feces collection portion 5, and may be provided outside the feces collection portion 5.
