[0049] Example 1

[0050] like Figure 1As shown, this embodiment provides a cleaning device for a water receiving box. The cleaning device is installed on the water receiving box and includes a controller 100, a liquid level detection module 200 that is communicatively connected to the controller 100, a plurality of primary cleaning mechanisms 300 and secondary cleaning mechanisms 400.

[0051] The primary cleaning mechanism 300 is located at the first preset bottom position of the water receiving box, and the secondary cleaning mechanism 400 is located at the second preset bottom position of the water receiving box. Both the primary cleaning mechanism 300 and the secondary cleaning mechanism 400 are connected to the interior of the water receiving box.

[0052] The liquid level detection module 200 is located at a preset fault detection point inside the water receiving box.

[0053] The controller 100 is used to receive a liquid level signal sent by the liquid level detection module 200, indicating that the water receiving box is blocked; the controller 100 is also used to receive the liquid level signal, generate a first drive command and send it to the first-level cleaning mechanism 300 to drive the first-level cleaning mechanism 300 to flush the blockage at the first preset bottom position and drain the water through the outlet.

[0054] After the set flushing time has elapsed, and while the controller 100 is still receiving the liquid level signal, the controller 100 is also used to generate a second drive command to drive the secondary cleaning mechanism 400 to discharge the blockage in the water receiving box at the second preset bottom position of the water receiving box while the primary cleaning mechanism is in the flushing state.

[0055] In this embodiment, the liquid level detection module is a liquid level probe. The number of liquid level detection modules can be designed or adjusted according to actual needs.

[0056] The water receiving box cleaning device provided in this disclosure uses a liquid level detection module to determine whether a blockage has occurred in the water receiving box, achieving real-time monitoring of the water receiving box's internal status. When a blockage occurs, a primary cleaning mechanism is activated to clean the water receiving box and remove the blockage. Through automatic detection and flushing, the frequency of manual inspection and cleaning is reduced, lowering maintenance costs. While the primary cleaning mechanism is processing the water receiving box, the liquid level detection module continues to detect whether a blockage has occurred. If the blockage persists, a secondary cleaning mechanism is activated to remove the blockage, preventing repeated blockages due to flushing failure that could affect the use of the water receiving box and further improving the user experience.

[0057] like Figure 2 As shown, the primary cleaning mechanism 300 in this embodiment includes: an inlet pipe 301, a first outlet pipe 302, an inlet solenoid valve 303, and a booster pump 304.

[0058] The inlet solenoid valve 303 is installed on the first outlet pipe 302; the controller 100 is used to drive the booster pump 304 and the inlet solenoid valve 303 to start based on the first drive command, so as to drive the first-stage cleaning mechanism to flush the blockage at the first preset bottom position and drain the water through the first outlet pipe.

[0059] The primary cleaning mechanism activates the flushing pipes when a blockage occurs in the water collection box. The high-pressure water jet from the booster pump disperses the blockage at the drain outlet, thus resolving the blockage and improving the user experience.

[0060] In this embodiment, the number of primary cleaning mechanisms is at least one.

[0061] When there are two or more primary cleaning mechanisms, the first drive command drives some or all of the primary cleaning mechanisms to perform the flushing operation together.

[0062] In one embodiment, when there are multiple primary cleaning mechanisms, some or all of the primary cleaning mechanisms can be driven to perform flushing operations simultaneously according to the first driving command, so as to improve the flushing quality of the blockage in the receiving water box; wherein, when some primary cleaning mechanisms malfunction, the flushing operation can be performed by driving the non-malfunctioning primary cleaning mechanisms, thereby solving the problem of blockage in the receiving water box and improving the user experience.

[0063] like Figure 2 As shown, the primary cleaning mechanism 300 in this embodiment also includes a manual control unit 305; the manual control unit 305 is electrically connected to the water inlet solenoid valve 303 and the booster pump 304.

[0064] The manual control unit is used to drive the booster pump and the inlet solenoid valve to start based on preset drive commands, so as to drive the first-stage cleaning mechanism to flush the blockage at the first preset bottom position and drain the water through the first outlet pipe.

[0065] The manual control unit provides operators with greater control flexibility and operational reliability. In specific situations, it can supplement or replace the automatic system, ensuring that the cleaning mechanism can effectively handle blockages.

[0066] like Figure 3 As shown, the secondary cleaning mechanism 400 in this embodiment includes: a second water outlet pipe 401 and a drain solenoid valve 402; the drain solenoid valve 402 is disposed on the second water outlet pipe 401; the controller is used to drive the drain solenoid valve to start based on a second drive command so that water flows through the second water outlet pipe and is discharged.

[0067] While the secondary cleaning unit is carrying out the cleaning operation, the primary cleaning unit is also performing the flushing operation.

[0068] In this embodiment, the number of secondary cleaning mechanisms is at least one; when the number of secondary cleaning mechanisms includes two or more, the driving part or all of the secondary cleaning mechanisms corresponding to the second driving command perform the rinsing operation together.

[0069] In one embodiment, when there are multiple secondary cleaning mechanisms, some or all of the secondary cleaning mechanisms can be driven to perform flushing operations simultaneously according to the second driving command, so as to improve the flushing quality of the blockage in the receiving water box; wherein, when some of the secondary cleaning mechanisms malfunction, the flushing operation can be performed by driving the non-malfunctioning secondary cleaning mechanisms, thereby solving the problem of blockage in the receiving water box and improving the user experience.

[0070] like Figure 1 As shown, the water collection box cleaning device in this embodiment also includes a prompting module 500; the prompting module 500 is communicatively connected to the controller 100; the prompting module 500 is used to generate a prompt signal indicating that the water collection box is in a blocked state.

[0071] like Figure 1 As shown, the cleaning device for the water receiving box in this embodiment also includes a display module 600; the display module 600 is communicatively connected to the controller 100 and the prompt module 500; the display module 600 is used to display and output the liquid level signal, or the prompt signal.

[0072] In one specific implementation, the display module is an electronic screen, which allows users to intuitively obtain the real-time status of the water collection box, further enhancing the user experience.

[0073] like Figure 1 As shown, the cleaning device for the water receiving box in this embodiment also includes a recording module 700; the recording module 700 is communicatively connected to the controller 100; the recording module 700 is used to record the actual number of times the primary cleaning mechanism performs drainage operations.

[0074] The controller 100 is also used to drive the secondary cleaning mechanism 400 to discharge the blockage in the water receiving box at the second preset bottom position of the water receiving box when the actual number of times reaches the preset number of times; wherein, the time corresponding to the preset number of times is the set time.

[0075] The implementation principle of the water collection box cleaning device of this disclosure is explained below with specific embodiments:

[0076] like Figure 4As shown, the cleaning device for the water receiving box includes: an electronic screen (a), a liquid level probe (b), a water outlet (c), a check valve (d), a drain outlet (e), a drain solenoid valve (f), a control module (g), a manual switch (h), a water inlet (i), a booster pump (g), a water receiving box (k), a water outlet (l), a drain solenoid valve (m), a control module (n), and a drain outlet (o).

[0077] The control module is used to open the inlet solenoid valve and the booster pump after receiving a signal. The control module includes a signal transmission device and a recording module and a drain solenoid valve control device. The signal transmission device and the recording module are used to receive and record the number of responses from the control module. The drain solenoid valve control device is used to open the drain solenoid valve after the control module receives a signal response.

[0078] A level probe is installed at half the water level height inside the side wall of the water receiving box. When the level probe detects a low water level, it sends a fault signal, which is displayed on the electronic screen. The size of the water receiving box is not fixed; the water level height can be adjusted according to the actual flow rate. This ensures that when the water purifier is in normal use and there is no blockage, the level probe will not be triggered.

[0079] The water outlet is located at the lower right of the water receiving box, slightly lower than the bottom of the water receiving box. The overall structure, welded to the bottom of the water receiving box, is funnel-shaped, which makes it easy for the water flowing into the water receiving box to gather at the water outlet and be discharged.

[0080] There are two branches at the bottom of the water receiving box. One branch is directly connected to the drain outlet for normal drainage, and the other branch is connected to a one-way valve to prevent water from flowing back into the pipe. The water inlet solenoid valve is connected below and controlled by the control module.

[0081] When the water receiving box is working normally, the inlet solenoid valve is kept closed. When the liquid level probe in the water receiving box detects the liquid level height, it indicates that there is a blockage in the water receiving box and the water flow is not smooth. A fault alarm will be displayed on the electronic screen and a signal will be sent to the control module at the same time.

[0082] After receiving the signal, the control module opens the inlet solenoid valve, and the booster pump starts working simultaneously. Water enters through the inlet, is pressurized by the booster pump, and then flows through the inlet solenoid valve and check valve to impact the branch pipe at the outlet, clearing blockages in the drainage pipe. If the water flow successfully washes away the blockage, the water in the collection box is successfully drained, and the level probe fails to detect the liquid level, the control module closes the inlet solenoid valve, the booster pump is powered off, the collection box blockage alarm on the electronic screen is cleared, and the collection box resumes normal operation.

[0083] The control module is also equipped with a manual switch, which can be manually turned on for flushing when the water level in the water tank has not reached the warning level.

[0084] When the water level probe in the receiving box detects a fault signal, the inlet solenoid valve of the outlet branch opens, and the booster pump starts flushing the drain pipe. If the water level probe can still detect the liquid level after three flushes, it indicates that the blockage in the receiving box cannot be resolved by flushing the pipe. At this point, the control module closes the inlet solenoid valve, the booster pump stops running, the control module receives a record signal indicating that the inlet solenoid valve has been opened three times consecutively, and then opens the drain solenoid valve to drain the water accumulated in the receiving box through the drain pipe.

[0085] The water outlet is positioned flush with the bottom of the water collection box, at a relatively high height, making it less prone to blockage by foreign objects. The drain solenoid valve on the connected water line is normally closed and does not perform its drainage function under normal circumstances. In the event of an unavoidable blockage, the water in the collection box is drained through the water outlet, maintaining the basic normal operation of the collection box. Simultaneously, a blockage fault signal is displayed on the electronic screen, awaiting manual resolution of the original drainage channel blockage.

[0086] Example 2

[0087] This embodiment provides a water dispenser, which includes the cleaning device for the water receiving box in embodiment 1.

[0088] The water dispenser provided in this disclosure can determine whether a blockage has occurred in the water receiving box through a liquid level detection module, realizing real-time monitoring of the status inside the water receiving box. When a blockage occurs in the water receiving box, a primary cleaning mechanism is activated to clean the water receiving box and remove the blockage. Through automatic detection and flushing, the frequency of manual inspection and cleaning is reduced, thus lowering maintenance costs. While the primary cleaning mechanism is processing the water receiving box, the liquid level detection module continues to detect whether a blockage has occurred in the water receiving box. If the blockage is still present, a secondary cleaning mechanism is activated to remove the blockage. This avoids the situation where the blockage problem recurs due to the failure of the flushing function and cannot be resolved in a timely manner, thereby affecting the use of the water receiving box and further improving the user experience.

[0089] While specific embodiments of this disclosure have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of this disclosure is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this disclosure, but all such changes and modifications fall within the scope of protection of this disclosure.
