Referring to fig. 1 and 2, fig. 1 is a schematic structural view of a first embodiment of the removable tissue dispenser of the present application, and fig. 2 is a schematic structural view of an embodiment of a stack of tissues housed by the removable tissue dispenser of fig. 1. In this embodiment, the dispenser 1 includes a case 10, a lid 20, a suction cup 30, and a pumping assembly 40.

Wherein, a paper extraction opening 11 is opened on the first side of the box body 10, and an accommodating space is formed inside the box body 10 for accommodating the paper towel stack 2. One end of the cover 20 is rotatably connected to one end of the first side of the case body 10 to be capable of rotating around the one end of the first side of the case body 10 to be away from or close to and cover the first side of the case body 10, that is, to open or close the cover 20.

In one embodiment, the folding mode of the plurality of tissues is V-shaped, and when the tissue at the topmost layer is sucked up, the adjacent tissue is exposed from the paper extraction opening 11, so as to be convenient for the next extraction. In other embodiments, the folding manner of the multiple tissues may also be set as a Z-type, a W-type or other folding manners, so as to ensure that the tissue closest to the paper extraction opening 11 in the stack 2, i.e. the uppermost tissue, is extracted, and then the adjacent tissues are simultaneously taken out to the paper extraction opening 11.

The suction cup 30 is further disposed on the cover 20, and is closely and fixedly connected to the surface of the cover 20 facing the side of the box 10, and is disposed opposite to the paper extraction opening 11 when the cover 20 covers the first side of the box 10.

The air extracting assembly 40 further includes a first structure housing 41, an air extracting cavity is formed inside the first structure housing 41, and the air extracting cavity is communicated with the suction cup 30 to extract air at the suction port of the suction cup 30 when the box cover 20 rotates around one end of the first side of the box body 10 away from the first side thereof, so as to generate a negative pressure at the suction port of the suction cup 30 to suck up the tissues near the paper extracting port 11 and extract them from the box body 10 for the user to extract, when the box cover 20 stops rotating, the air extracting assembly 40 stops extracting air, when part of the sucked tissues are taken away by the user, and after the cover body 20 is closed, the normal pressure is restored at the suction port of the suction cup 30.

It can be understood that the tissues sucked by the suction cup 30 each time are the partial tissues located in the tissue stack 2 in the box body 10 and closest to the tissue extraction opening 11, and when the box cover 20 is opened, the partial tissues in the tissue stack 2 and close to the tissue extraction opening 11 are sucked out of the tissue extraction opening 11 by the suction cup 30, so that the situation that a user puts hands into the box body 10 to extract the tissues is effectively avoided, and after the partial tissues are extracted, the partial tissues do not need to be kept to stretch out of the tissue extraction opening 11, the user can conveniently extract the tissues next time, the process of extracting the tissues is convenient and rapid, the sanitary cleanliness of the tissue stack 2 is effectively ensured, and unnecessary waste of the tissues is avoided.

In another application scenario, after the user draws out a part of the tissues, a part of the tissues can be kept to extend out of the tissue drawing opening 11, the box cover 20 is closed to ensure the cleanliness of the part of the tissues exposed out of the tissue drawing opening 11, and when the box cover 20 is opened again, the tissues in the box body 10 are further sucked out for the user to draw out.

Wherein, the suction cup 30 comprises at least one suction opening, and the at least one suction opening is arranged at one side of the suction cup 30 close to the paper extraction opening 11 and is directly contacted with the paper towel in the box body 10 at the paper extraction opening 11. And when the suction port is provided in plural, plural suction ports are provided at intervals on the side of the suction cup 30 close to the paper extraction port 11. The suction cup 30 is provided at the other side with a hose 31, through which hose 31 the suction cup 30 can communicate with a suction cavity formed inside a first structural shell 41 of the suction assembly 40.

Alternatively, the hose 31 may be one of a stainless steel hose, a metal hose, a corrugated hose, a rubber hose, a plastic hose, or the like, which is not limited in this application.

Optionally, the box body 10 is one of three-dimensional structures such as a cuboid, a cube, and a cylinder, in which an accommodating space is formed, and this is not limited in this application.

Optionally, the first structural casing 41 of the air exhaust assembly 40 is a cylindrical structure with an air exhaust cavity formed therein, and in other embodiments, the air exhaust cavity formed by the first structural casing 41 may be one of any reasonable cube such as an elliptical cylinder, a rectangular parallelepiped, and a square, which is not limited in this application.

Referring to fig. 3-6 in combination, fig. 3 is a front view of one embodiment of the suction assembly in the extraction tissue dispenser of fig. 1, fig. 4 is a cross-sectional view of another embodiment of the suction assembly in the extraction tissue dispenser of fig. 1, fig. 5 is a schematic top view of a suction piston in the suction assembly of fig. 4, and fig. 6 is a cross-sectional view of yet another embodiment of the suction assembly in the extraction tissue dispenser of fig. 1.

In one embodiment, the air-extracting assembly 40 further comprises an air-extracting piston 43, an air-extracting support rod 42, an air-extracting valve 411 and a deflation valve 412. The side surface of the air extracting piston 43 is tightly attached to the inner wall of the first structure housing 41 of the air extracting assembly 40, so as to divide the air extracting cavity formed by the first structure housing 41 into a first air extracting cavity and a second air extracting cavity. It can be understood that the first air-extracting cavity is a cavity formed on the side of the air-extracting piston 43 facing the air-extracting support rod 42, and the second air-extracting cavity is a cavity formed on the side of the air-extracting piston 43 opposite to the air-extracting support rod 42.

One end of the air-extracting support rod 42 is connected to the rotational connection position of the box cover 20 and the box body 10, and the other end of the air-extracting support rod 42 is disposed on an end surface of the air-extracting piston 43 facing the air-extracting support rod 42. The suction valve 411 and the purge valve 412 are respectively disposed at predetermined positions on the first structural housing 41 corresponding to a first suction chamber, and the first suction chamber can suck or discharge gas through the suction valve 411 and the purge valve 412.

Optionally, a rubber collar (not shown) is disposed at a boundary of the air exhaust support rod 42 penetrating through the first structural casing 41, so as to ensure that an air exhaust cavity cannot leak from the boundary of the air exhaust support rod 42 and the first structural casing 41, and the air exhaust support rod 42 can move in the air exhaust cavity.

The air extracting valve 411 and the air releasing valve 412 are both one-way valves, that is, the air extracting valve 411 can only suck air from the outside of the first structure housing 41 into the first air-extracting cavity, and the air releasing valve 412 can only discharge air from the inside of the first air-extracting cavity to the outside of the first structure housing 41.

The suction cup 30 is connected to the first pumping cavity through the suction valve 411, so that when the lid 20 rotates around the first side of the box 10, the air pumping support rod 42 is driven to move, and the air pumping support rod 42 further drives the air pumping piston 43 to reciprocate in the pumping cavity, so as to generate a negative pressure at the position of the suction cup 30 through the suction cup 30 and the suction valve 411 to suck up the paper towel near the paper pumping port 11, or exhaust the air in the first cavity through the air release valve 412, so as to restore the position of the suction cup 30 to the normal pressure.

In other embodiments, the air pumping assembly 40 can also directly suck air through the suction cup 30 to generate a negative pressure at the position of the suction cup 30 to suck up the paper towel near the paper pumping port 11, and directly exhaust the air in the first cavity through the suction cup 30 to return the position of the suction cup 30 to the normal pressure without providing the suction valve 411 and the air release valve 412.

Specifically, when the box cover 20 rotates away from the first side of the box body 10, that is, during the opening of the box cover 20, the air extracting piston 43 moves back to the air extracting support rod 42 in the air extracting cavity, the air extracting valve 411 is opened, the air flow flows from the suction cup 30 to the first air extracting cavity, a negative pressure is formed at the suction port of the suction cup 30, the paper towel near the paper extracting port 11 in the box body 10 is sucked up and extracted, and during this process, the air release valve 412 is in a closed state under the squeezing action of the air flow in the first air extracting cavity.

When the box cover 20 rotates to approach the first side of the box body 10, that is, during the process of closing the box cover 20, the air-extracting piston 43 moves and resets in the air-extracting cavity facing the air-extracting support rod 42, the air-extracting valve 411 is closed, the air-releasing valve 412 is opened under the squeezing action of the airflow in the first air-extracting cavity, the excess air in the first air-extracting cavity is released from the air-releasing valve 412, and the excess air in the suction cup 30 is released from the suction port thereof, so that the suction port is returned to normal pressure.

A fixed shaft is disposed at one end of the first side of the box body 10, and a shaft sleeve which can rotate relative to the fixed shaft is correspondingly disposed on the box cover 20, so that when the box cover 20 is opened, the shaft sleeve can rotate around the fixed shaft in a counterclockwise direction, and when the box cover 20 is closed, the shaft sleeve rotates around the fixed shaft in a clockwise direction.

Further, one end of the air-extracting support rod 42 is connected to the shaft sleeve, so that when the lid 20 is opened or closed, the air-extracting support rod 42 drives the air-extracting piston 43 to reciprocate in the air-extracting cavity.

In an embodiment, as shown in fig. 3, the air-extracting cavity formed inside the first structure housing 41 of the air-extracting component 40 is a column structure that is arc-shaped in a direction perpendicular to the first side surface of the box body 10, so that when the box cover 20 is opened or closed, the air-extracting support rod 42 can drive the air-extracting piston 43 to make the side surface of the air-extracting piston always cling to the inner wall of the first structure housing 41 to make reciprocating movement along the arc shape inside the air-extracting cavity.

It can be understood that, in the process of opening or closing the box cover 20, the direction of the force applied by the air-extracting support rod 42 to the air-extracting piston 43 is constantly changed, wherein, when the first structural shell 41 of the air-extracting assembly 40 is set to be an arc-shaped cylinder structure in the direction perpendicular to the first side surface of the box body 10, and the arc shape is ensured to match with the motion track of the air-extracting support rod 42 set at the other end of the air-extracting piston 43, it can be ensured that the side surface of the air-extracting piston 43 can be always tightly attached to the inner wall of the first structural shell 41 in the process of driving the air-extracting piston 43 to reciprocate in the air-extracting cavity along the arc shape by the air-extracting support rod 42.

In another embodiment, as shown in fig. 4 and 5, a movable sliding rail 431 is disposed on an end surface of the air extracting piston 43 facing the air extracting support rod 42, and the other end of the air extracting support rod 42 is disposed inside the movable sliding rail 431, so that when the box cover 20 rotates around one end of the first side surface of the box body 10, the other end of the air extracting support rod 42 can reciprocate in the movable sliding rail 431 to drive the air extracting piston 43 to reciprocate in the air extracting cavity.

The extending direction of the movable sliding rail 431 is perpendicular to the second side of the box 10, and the end of the other end of the air-extracting support rod 42 may be a cylinder structure which is perpendicular to the extending direction of the air-extracting support rod 42 and can roll back and forth along the movable sliding rail 431. It can be understood that the side of the movable rail 431 facing the air-extracting support rod 42 is further provided with a baffle plate for limiting the movement of the end of the other end of the air-extracting support rod 42 to the direction close to the first side of the box body 10.

In another embodiment, as shown in fig. 6, the pumping support rod 42 includes a first support rod 421 and a second support rod 422, one end of the first support rod 421 and one end of the second support rod 422 are both connected to the rotational connection position of the box cover 20 and the box body 10, and the other end of the first support rod 421 and the other end of the second support rod 422 are respectively and fixedly connected to a predetermined position on one end surface of the pumping piston 43 and form a predetermined angle with the pumping piston 43.

Wherein, first bracing piece 421 and second bracing piece 422 respectively with bleed piston 43 fixed connection's default position to guarantee opening or closing the in-process of lid 20, can drive the stable and not inclined reciprocating motion in the aspirating cavity of bleed piston 43 for the standard.

With continuing reference to fig. 7-8, fig. 7 is a schematic view of a second embodiment of the removable towel dispenser of the present application, and fig. 8 is a cross-sectional view of a lifting device in the removable towel dispenser of fig. 7.

In one embodiment, the removable tissue dispenser 1 further comprises a lifting device 60, the lifting device 60 is connected to the box cover 20 at a position where the box cover 20 is rotatably connected to the box body 10, so that when the box cover 20 is rotated around one end of the first side of the box body 10 away from the first side, i.e. the box cover 20 is opened, the lifting device 60 can drive the tissue stack 2 to move towards the direction close to the tissue extraction opening 11, thereby avoiding an embarrassing situation that the tissue exposed out of the tissue extraction opening 11 can not be sucked up and extracted again after falling into the box body 10 due to the fact that the tissue stack 2 is too far away from the tissue extraction opening 11, and further facilitating the tissue extraction.

It can be understood that as the user continuously extracts the tissues contained in the box 10, the quantity of the tissues is continuously reduced, and the distance from the tissue stack 2 to the tissue extraction opening 11 is further increased, so that the tissues exposed to the tissue extraction opening 11 cannot be sucked and extracted by the air extraction assembly 40 after falling back into the box 10.

Specifically, as shown in fig. 7 and 8, the lifting device 60 further includes a driving component 61 and a supporting component 62 connected to each other, wherein the driving component 61 is connected to the box cover 20 at a position where the box cover 20 is rotatably connected to the box body 10, the supporting component 62 is disposed inside the box body 10, and the stack of tissues 2 is disposed on the supporting component 62, so that when the box cover 20 rotates around one end of the first side of the box body 10 away from the first side thereof, i.e., when the box cover 20 is opened, the driving component 61 drives the supporting component 62 to move toward the direction close to the tissue extraction opening 11, so that the supporting component 62 further drives the stack of tissues 2 to move toward the direction close to the tissue extraction opening 11.

Optionally, the driving assembly 61 further includes a second structural housing 611, a third supporting rod 612 and a first piston 613, the supporting assembly 62 further includes a supporting plate 621, a third structural housing 622 and a second piston 623, a first cavity is formed inside the second structural housing 611, a second cavity is formed inside the third structural housing 622, and the first cavity and the second cavity are communicated through a closed channel 63.

One end of the third supporting rod 612 is connected to the position where the box cover 20 is rotatably connected to the box body 10, the other end of the third supporting rod 612 is disposed on one end surface of the first piston 613, the supporting plate 621 is disposed on the second piston 623, and the tissue stack 2 is disposed on the supporting plate 621. In other embodiments, the stack 2 of tissues can also be directly disposed on the second piston 623 without disposing the supporting plate 621, which is not limited in this application.

Alternatively, the supporting plate 621 is made of any reasonable material such as cardboard, wood board, plastic board, etc., and the area of one end surface thereof is set to be smaller than the area of the cross section of the box body 10.

Therefore, when the box cover 20 rotates around the end of the first side of the box body 10 away from the first side, that is, when the box cover 20 is opened, the third support rod 612 can be driven to move, the third support rod 612 further drives the first piston 613 to move in the direction away from the first side of the box body 10 in the first cavity, and pushes the second piston 623 to move towards the direction close to the paper extraction opening 11 through the closed channel 63, and the second piston 623 further drives the support plate 621 to move towards the direction close to the paper extraction opening 11, so that the support plate 621 drives the paper towel stack 2 to move towards the direction close to the paper extraction opening 11.

Wherein, be provided with inflation valve 631 and inhalation valve 632 on the closed channel 63, and inflation valve 631 and inhalation valve 632 are the check valve, and inflation valve 631 is used for communicateing first cavity and second cavity to make the air in the first cavity can one-wayly flow in the second cavity, and inhalation valve 632 sets up in the preset position department that second structure shell 611 corresponds to first cavity, or closed channel 63 is close to the preset position department of first cavity, so that the first cavity can inhale the air.

In the process of opening the box cover 20, the first piston 613 moves a first preset distance in the first cavity away from the third support rod 612, at this time, the air charging valve 631 is opened, the air suction valve 632 is closed, and air in the first cavity enters the second cavity through the air charging valve 631 to push the second piston 623 to move a second preset distance toward the paper extraction opening 11, so as to drive the stack of paper towels 2 to move the second preset distance toward the paper extraction opening 11.

During the process of closing the box cover 20, the first piston 613 moves towards the third supporting rod 612 in the first cavity, at this time, the charging valve 631 is closed, the suction valve 632 is opened, and the external air enters the first cavity through the suction valve 632 to push the second piston 623 to move next time, and the process is repeated.

It is understood that the first predetermined distance is the distance that the first piston 613 moves during the process of opening the box cover 20, and the second predetermined distance is determined by the distance that the first piston 613 moves and the ratio of the volumes of the first cavity and the second cavity, so that the distance that the tissue stack 2 moves towards the tissue extraction opening each time the box cover 20 is opened can be reasonably set by reasonably setting the length of the third support rod 612, the volume of the first cavity, and the ratio of the volumes of the first cavity and the second cavity, that is, by reasonably setting the second predetermined distance, the distance that the tissue stack 2 moves towards the tissue extraction opening each time the box cover 20 is opened is approximately equal to the thickness of the tissue that is usually extracted each time, so as to ensure that the tissue stack 2 gradually rises with the consumption of the tissue during the use of the removable tissue dispenser 1, and the tissue of the tissue stack 2 closest to the tissue extraction opening 11 is always located at approximately the same height, namely, the distance between the paper towel and the paper extraction opening 11 is approximately unchanged so as to be convenient for sucking and extracting, and the embarrassing situation that the paper towel cannot be sucked and extracted due to the fact that the paper towel is too far away from the paper extraction opening 11 is avoided, so that the paper towel is more convenient to extract.

Optionally, a gas release switch 70 is disposed on the third structural shell 622 at a preset position corresponding to the second cavity, so that when the gas release switch 70 is turned on, the gas in the second cavity can be discharged.

It can be appreciated that when the second piston 623 is raised to a position close to the paper extraction opening 11, that is, when the tissues in the box 10 are nearly used or used completely, the air release switch 70 can be opened to release air from the second chamber, so that the second piston 623 falls back to the initial position to achieve the reuse of the extraction tissue dispenser 1, which is convenient and environmentally friendly.

Preferably, the driving assembly 61 and the air extracting assembly 40 are the same assembly, that is, the second structure housing 611, the third supporting rod 612 and the first piston 613 are respectively equal to the first structure housing 41, the air extracting supporting rod 42 and the air extracting piston 43, and the driving assembly 61 and the air extracting assembly 40 have the same technical features and corresponding connection relationships, so as to save the storage space for installing the removable tissue dispenser 1 and reduce the corresponding manufacturing cost, which is not described herein again.
