The first embodiment:

referring to fig. 1 and 2, an embodiment of the present invention provides a water treatment apparatus 10, which includes a base 100 and a filter element 200, wherein the base 100 is used for installing the filter element 200.

In detail, referring to fig. 3 and 4, the base 100 includes a chassis 110, a rotating bracket 120, a motor 140, a detecting element and a controller 130. The rotating bracket 120 is rotatably provided to the base plate 110. The motor 140 is disposed on the bottom plate 110 and is in transmission connection with the rotating bracket 120, and is used for driving the rotating bracket 120 to rotate so as to lock or unlock the filter cartridge 200. The detecting member is disposed on the chassis 110 for detecting a position of the rotating bracket 120. The controller 130 is electrically connected to both the sensing member and the motor 140 for controlling the operation of the motor 140 according to the position of the rotating bracket 120.

When the filter element 200 is mounted on the base 100, the controller 130 controls the motor 140 to drive the rotating bracket 120 to rotate relative to the base plate 110, so that the filter element 200 is automatically locked or unlocked without manual operation, thereby facilitating the assembly and disassembly operation of the filter element 200 and effectively improving the assembly and disassembly efficiency of the filter element 200.

The rotary bracket 120 can adopt different structures to lock or unlock the filter cartridge 200 as required. In this embodiment, the bottom plate 110 is substantially annular and cooperates with the rotational support 120 to define a positioning cavity that mates with the bottom of the filter cartridge 200. The rotating bracket 120 is provided with a catch 122, and the catch 122 can rotate with the rotating bracket 120. The bottom of the filter element 200 is provided with a projection 210 which is used for abutting against and matching with the buckle 122 of the rotating bracket 120, when the filter element 200 needs to be installed, the buckle 122 rotates to a position avoiding the projection 210 of the filter element, the projection 210 can be clamped into the installation cavity along with the bottom of the filter element 200, and after the bottom of the filter element 200 is clamped into the installation cavity, the buckle 122 can rotate to a position corresponding to the projection 210 of the filter element 200 so as to limit the filter element 200 to be separated from the base 100 and realize the locking of the filter element 200. When the filter cartridge 200 needs to be removed, the latch 122 is rotated again to a position avoiding the protrusion 210 of the filter cartridge 200, so that the filter cartridge 200 can be separated from the base 100, and the filter cartridge 200 can be unlocked. The rotating bracket 120 is further provided with a first detecting piece 124 and a second detecting piece 126, and the first detecting piece 124 and the second detecting piece 126 are arranged at intervals around the axis of the rotating bracket 120.

The structure of the detecting member can be set as required, and in this embodiment, the detecting member includes a first detector 112, a second detector 114 and a third detector 116, which are all set on the chassis 110. The first detector 112 is configured to detect whether the rotary bracket 120 is in a first position for unlocking the filter cartridge 200, and the second detector 114 is configured to detect whether the rotary bracket 120 is in a second position for locking the filter cartridge 200. The third detector 116 is used to detect whether the filter cartridge 200 is mounted on the base 100. With the rotary bracket 120 in the first position or the second position, the controller 130 is configured to control the operation of the motor 140 according to whether the filter cartridge 200 is mounted to the base 100.

The type of the detecting member can also be set according to the requirement, and the detecting member can be a micro switch, a magnetic reed switch or a photoelectric sensor. In this embodiment, the first detector 112, the second detector 114, and the third detector 116 are all micro switches, and the micro switches have the characteristics of sensitive detection and high precision, and can effectively detect the state of the filter element 200 and the position of the rotating bracket 120. The first detector 112 is triggered after being abutted by the first detecting piece 124, that is, when the rotating bracket 120 rotates to the position of the unlocking filter element 200, the first detecting piece 124 just abuts against the first detector 112; the second detector 114 is triggered by the second detecting piece 126 abutting against the second detecting piece, that is, when the rotating bracket 120 rotates to the position of locking the second filter element 200, the second detecting piece 126 just abuts against the second detector 114.

In other embodiments, the first detector 112, the second detector 114, and the third detector 116 may be all reed switches or photosensors, but the three detectors may also be configured differently, such as micro switches, reed switches, and photosensors.

Further, referring to fig. 4 again, the base 100 further includes an unlocking button 118 electrically connected to the controller 130, the unlocking button 118 is configured to send an unlocking instruction to the controller 130, and the controller 130 is configured to respond to the unlocking instruction to control the motor 140 to drive the rotating bracket 120 to rotate to the first position for unlocking the filter element 200. When the filter cartridge 200 needs to be replaced or maintained, a user can press the unlocking button 118, the unlocking button 118 sends an unlocking instruction to the controller 130, and when the controller 130 receives the unlocking instruction, the output shaft of the motor 140 is controlled to rotate, the rotating bracket 120 is driven to rotate to the first position for unlocking the filter cartridge 200, so that the user can detach the filter cartridge 200 from the base 100.

The working principle and process of the base 100 are as follows:

when the filter element 200 needs to be installed, the controller 130 controls the motor 140 to drive the rotating bracket 120 to rotate to the first position, so that the buckle 122 avoids the projection 210 of the filter element 200, and after the bottom of the filter element 200 is clamped into the installation cavity, the controller 130 controls the motor 140 to drive the rotating bracket 120 to rotate to the second position, so that the buckle 122 abuts against the projection 210 of the filter element 200, the filter element 200 is prevented from being separated from the base 100, the locking of the filter element 200 is realized, and the installation of the filter element 200 is completed.

When the filter element 200 needs to be removed, the controller 130 controls the motor 140 to drive the rotating bracket 120 to rotate to the first position again, so that the buckle 122 avoids the projection 210 of the filter element 200, and the filter element 200 can be separated from the base 100, that is, the filter element 200 is unlocked, and a user can remove the filter element 200 from the base 100 for replacement or maintenance.

The locking and unlocking of the filter element 200 are completed by the controller 130 controlling the motor 140 to rotate during the driving no matter whether the filter element is installed or removed, and the manual operation of a user is not needed, so that the assembling and disassembling operation of the filter element 200 can be facilitated, and the assembling and disassembling efficiency of the filter element 200 can be improved.

It should be noted that the number of the base 100 adapted to the filter cartridge 200 can be determined according to the requirement, in this embodiment, the base 100 is adapted to two filter cartridges 200, and in other embodiments, the base 100 may also be one, three, or four. When the base 100 is adapted to more than two filter cartridges 200, the motors 140 corresponding to each filter cartridge 200 can be shared or independent.

Second embodiment:

referring to fig. 5, an embodiment of the present invention provides a motor control method for controlling the operation of the motor 140 of the base 100 in the first embodiment. The motor control method comprises the following steps:

step S100: the position of the rotating bracket 120 is acquired. The position of the rotating bracket 120 is detected by the first detector 112 and the second detector 114 and then sent to the controller 130. The rotating bracket 120 has three positions relative to the chassis 110, which are a first position, a second position, and a third position between the first position and the second position, and whether the rotating bracket 120 is in the first position is detected by the first detector 112 and transmitted to the controller 130, whether the rotating bracket 120 is in the second position is detected by the second detector 114 and transmitted to the controller 130, and when the rotating bracket is in neither the first position nor the second position, the rotating bracket is in the third position. When the rotational stand 120 is in the first position, the cartridge 200 is unlocked, when the rotational stand 120 is in the second position, the cartridge 200 is locked, and when the rotational stand 120 is in the third position, the cartridge 200 is neither unlocked nor locked, and can be considered to be in a half-locked state.

Step S200: the operation of the motor 140 is controlled according to the position of the rotating bracket 120.

Referring to fig. 6 and 7, in the present embodiment, the step of controlling the operation of the motor 140 according to the position of the rotating bracket 120, that is, the step S200, specifically includes:

in the case where the rotary bracket 120 is in the first position to unlock the filter cartridge 200 or the second position to lock the filter cartridge 200, step S300 is performed: the operation of the motor 140 is controlled according to whether the filter cartridge 200 is mounted to the base 100. Whether the filter cartridge 200 is mounted to the base 100 can be detected by the third detector 116 and sent to the controller 130.

In detail, when the rotary bracket 120 is in the first position to unlock the filter cartridge 200 and the filter cartridge 200 is mounted on the base 100, step S310 is performed: the control motor 140 drives the rotary bracket 120 to rotate to the second position for locking the filter cartridge 200, so as to lock the filter cartridge 200, and the filter cartridge 200 starts to work normally.

Further, referring to fig. 8, the step of controlling the motor 140 to drive the rotating bracket 120 to rotate to the second position of the locking filter element 200, that is, step S310, specifically includes:

step S312: the control motor 140 drives the rotary bracket 120 to rotate toward the second position locking the filter cartridge 200.

If the rotating bracket 120 rotates to the second position within the first time, step S314 is executed: the control motor 140 is stopped after continuing to operate for the second time. When the rotary bracket 120 starts from the first position, moves to the third position, and reaches the second position, it is detected by the second detector 114, and sends an electric signal to the controller 130, and after the controller 130 receives the electric signal, the controller 140 controls the motor 140 to continue to operate for the second time and then stop, and at this time, the filter cartridge 200 is locked.

The first time may be set according to actual conditions, and may be generally set to be slightly longer than a normal time for the rotating bracket 120 to rotate from the first position to the second position, and the normal time may be calculated according to the rotating speed of the rotating bracket 120 or the motor 140 and the distance between the first position and the second position.

The second time can be set according to actual requirements, and is preferably 1S-2S. In this embodiment, the second time is 1S, and in other embodiments, the second time may also be 1.5S or 2S. After the second detector 114 detects that the rotating bracket 120 reaches the second position, the motor 140 is not directly stopped, but stopped after delaying the second time, because the detection of the detecting element must have a certain error, and when the detecting element is triggered, the rotating bracket 120 is not completely in place actually, so that the motor 140 is controlled to stop after delaying the second time, and the second rotating bracket 120 can be effectively ensured to be completely in place. Of course, it should be noted that in other embodiments, if the requirement on the position accuracy of the filter cartridge 200 is not high, the motor 140 may be controlled to stop directly when the second detector 114 detects the rotating bracket 120.

If the rotating bracket 120 is not rotated to the second position within the first time, step S316 is performed: and (6) alarming. After the first time of rotation of the rotating bracket 120, it is still not detected by the second detector 114, which indicates that the whole apparatus is out of order, and at this time, an alarm is required to remind the user to perform manual viewing and processing. The alarm may be in many forms, such as a controller 130 controlling a light alarm and a buzzer alarm.

Further, referring to fig. 7 again, after controlling the motor 140 to drive the rotating bracket 120 to rotate to the second position of the locking filter element 200, that is, after step S310, the method includes:

if the unlock instruction is received, step S318 is executed: the control motor 140 drives the rotary bracket 120 to rotate to a first position for unlocking the filter cartridge 200. The unlock command is triggered by the user pressing the unlock button 118, the trigger time being determined by the actual requirements.

In the case where the rotary bracket 120 is in the second position where the filter cartridge 200 is locked and the filter cartridge 200 is not mounted to the base 100, step S318 is performed: the control motor 140 drives the rotary bracket 120 to rotate to a first position for unlocking the filter cartridge 200. If the cartridge 200 is in the second position but the cartridge 200 is not installed, then control is required to rotate the rotational support 120 to the first position for installation of the cartridge 200. If the rotary bracket 120 is in the second position locking the filter cartridge 200 and the filter cartridge 200 is mounted to the base 100, the filter cartridge 200 can directly start normal operation without controlling the operation of the motor 140.

The step of controlling the operation of the motor 140 according to the position of the rotating bracket 120, that is, step S200, specifically further includes:

in the case where the rotary bracket 120 is in the third position where neither the filter cartridge 200 nor the filter cartridge 200 is locked, step S318 is performed: the control motor 140 drives the rotary bracket 120 to rotate to a first position for unlocking the filter cartridge 200. If the rotating bracket 120 is not in the first position or the second position, it is necessary to be in the third position, and then the motor 140 is directly controlled to drive the rotating bracket 120 to rotate to the first position. If the first detector 112 still does not detect that the rotating bracket 120 reaches the first position after the rotating bracket 120 rotates for the third time, or if the rotating bracket 120 is in the third position again after rotating to the first position and is maintained for the third time, it indicates that the whole apparatus is out of order, and then step S316, i.e. alarm, is performed to allow the user to manually view and process the apparatus, and if necessary, the apparatus is stopped for maintenance. The third time is determined according to actual conditions, and the determination method of the first time can be specifically referred to. The motor control method can realize the automatic rotation of the rotary bracket 120 by controlling the operation of the motor 140, thereby realizing the automatic locking or unlocking of the filter element 200, further effectively facilitating the installation and the disassembly of the filter element 200 and improving the efficiency of the assembly and disassembly operation of the filter element 200.

It should be noted that the motor control method provided in the embodiment of the present invention is described with respect to a single filter cartridge 200, and if the base 100 is adapted with a plurality of filter cartridges 200, for example, two, three, or four filter cartridges 200, the motor control method only needs to be sequentially executed for each filter cartridge 200, and certainly, the motor control method may also be executed for some or all of the filter cartridges 200 at the same time.

The third embodiment:

referring to fig. 9, an embodiment of the invention provides a motor control device 300, which is used in the controller 130 of the first embodiment to control the motor 140 of the base 100 of the first embodiment to operate according to the motor control method of the second embodiment. The motor control apparatus 300 includes an acquisition module 310 and a control module 320. The acquiring module 310 is used for acquiring the position of the rotating bracket 120; the control module 320 is configured to control operation of the motor 140 based on the position of the rotating gantry 120.

The motor control device 300 can realize the automatic rotation of the rotary bracket 120 by controlling the operation of the motor 140, thereby realizing the automatic locking or unlocking of the filter element 200, further effectively facilitating the installation and the disassembly of the filter element 200 and improving the efficiency of the assembly and disassembly operations of the filter element 200.

The above description is only for the specific embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
