Description

Technical Field

[0001] This invention relates to the field of intelligent pet feeding equipment technology, specifically to a pet cage waste collection and cleaning device and its control method. Background Technology

[0002] Existing pet cage cleaning equipment generally suffers from drawbacks such as low intelligence, crude cleaning methods, high risk of overflow, and limited applicability to specific scenarios. Most devices use a single detection component, which cannot simultaneously ensure accurate location of waste and detection of overflow or blockage in the waste collection container. They consume a large amount of water during rinsing and can only be used with a single mode of waste collection bucket or drain pipe, failing to address waste disposal issues from multiple perspectives. Their sealing and odor prevention effects are also poor, making it difficult to meet the needs of pet owners for convenience and hygiene. Summary of the Invention

[0003] This invention aims to overcome the shortcomings of existing technologies and provides a pet cage waste collection and cleaning device and its control method. It achieves precise cleaning and anti-overflow and anti-clogging protection through dual independent detection units, is compatible with multiple waste collection modes, has a wide protection range, and has outstanding novelty, inventiveness and practicality.

[0004] The technical solution of this invention is as follows: A pet cage waste collection and cleaning device includes a supporting base, a waste collection and guiding section, a normally closed sealing valve connected to the waste discharge end of the waste collection and guiding section, and a waste collection section connected below the sealing valve; a water storage component is provided on the side of the waste collection section, and the water storage component is connected to a high-pressure flushing unit, which has multiple flushing ends facing different working surfaces of the waste collection and guiding section; the device also includes a control module, a first state detection unit, and a second state detection unit, the control module being electrically connected to the sealing valve, the high-pressure flushing unit, the first state detection unit, and the second state detection unit respectively; the first state detection unit is used to detect the waste distribution state of the waste collection and guiding section, and the second state detection unit is used to detect the overflow, blockage, or in-place state of the waste collection section.

[0005] Furthermore, the waste collection section is a detachable waste collection bucket or a waste discharge pipe, and the sealing valve is a normally closed sealing valve.

[0006] Furthermore, when the second state detection unit does not detect the presence of the sludge collection tank, the control module prohibits the flushing action to prevent accidental spraying.

[0007] Furthermore, the first state detection unit and the second state detection unit are selected from one or more combinations of visual sensors, infrared sensors, ultrasonic sensors, radar sensors, and laser sensors.

[0008] The control method of this invention is as follows: A dual detection unit collects signals for dirt, overflow, blockage, and presence in real time. The control module performs logical judgments and initiates the flushing process only when "dirt is present + not overflowing or blocked + the drain component is in place." The valve is opened first, followed by flushing; after flushing, the water is turned off first, followed by the valve. If overflow, blockage, or absence of a drain component is detected, the flushing function is immediately locked to prevent overflow, leakage, and odor spread. Simultaneously, the corresponding flushing end is opened according to the location of the dirt, achieving water-saving and efficient cleaning.

[0009] The beneficial effects of this invention are: the dual independent detection units have clear division of labor, high detection accuracy, and avoid the detection error of a single sensor; it is compatible with sludge collection tanks and direct discharge into sewers, and is suitable for a wide range of scenarios; the normally closed sealing design completely blocks odors, and the overflow-prohibition flushing and blockage-prohibition flushing logic prevents overflow and backflow; the directional flushing is water-saving and environmentally friendly, the control logic is simple and reliable, the overall technical solution has not been disclosed by existing technology, it has significant inventiveness, the protection scope covers multiple sensor types and collection modes, and it is not easy to be circumvented.

[0010] Figure 1 is a schematic diagram of the overall structure of the pet cage waste collection and cleaning device provided in an embodiment of the present invention; Figure 2 is a schematic diagram of the pet cage waste collection and cleaning device provided in an embodiment of the present invention from another perspective; The following components are marked in the figure: bearing base (1), sewage guide section (2), sealing valve (3), sewage collection section (4), water storage assembly (5), high-pressure flushing unit (6), solenoid valve (7), spray head (8), first state detection unit (9) and second state detection unit (10). Detailed Implementation

[0011] The present invention will be further described in detail below with reference to specific embodiments.

[0012] The sludge collection and diversion section (2) is set on the supporting base (1), with the flushing area above it. The sludge discharge end of the sludge collection and diversion section (2) is connected to the sealing valve (3), and the bottom of the sealing valve (3) is connected to the sludge collection section (4). The sludge collection section (4) is a detachable sludge collection bucket or sludge discharge pipe. The water storage component (5) is connected to the high-pressure flushing unit (6). The high-pressure flushing unit (6) controls the opening and closing of the spray head (8) through the solenoid valve (7). Multiple spray heads (8) correspond to different flushing areas of the sludge collection and diversion section (2) to achieve single-sided / Directional flushing; the first state detection unit (9) is used to detect the dirt distribution state of the dirt collection guide section (2), and the second state detection unit (10) is used to detect the overflow state, blockage state and presence or absence of the dirt collection tank in the dirt collection section (4); the control module is electrically connected to the sealing valve (3), the high-pressure flushing unit (6), the solenoid valve (7), the first state detection unit (9), and the second state detection unit (10) respectively, and is used to receive detection signals and control the coordinated operation of each component.

[0013] The control method for this device includes the following steps: S1: The device is started. The water storage component (5) is filled with clean water in advance and provides stable water pressure for the high-pressure flushing unit (6). The first state detection unit (9) and the second state detection unit (10) enter the real-time detection state simultaneously, continuously collect relevant signals and transmit them to the control module. The first state detection unit (9) performs a comprehensive detection on the flushing area of ​​the sewage collection guide (2), collects the dirt distribution signal (including dirt location and dirt amount) in the area, and feeds the signal back to the control module in real time. The second state detection unit (10) performs multiple detections on the sewage collection part (4), and collects the overflow signal, blockage signal and whether the sewage collection component is in place of the sewage collection part (4) at the same time, and feeds the signal back to the control module simultaneously.

[0014] S2: The control module receives the dirt distribution signal transmitted by the first state detection unit (9), the overflow signal, the blockage signal and the presence signal transmitted by the second state detection unit (10), and makes a comprehensive judgment to clarify the core status: First, whether there is dirt in the flushing area of ​​the dirt collection guide (2) and the specific location of the dirt; Second, whether the dirt collection part (4) is in an overflow state, a blockage state, or whether there is a dirt collection component in place.

[0015] S3: The control module performs the corresponding operation according to the judgment result. If it is determined that there is dirt in the flushing area of ​​the dirt collection guide (2) and the dirt collection part (4) is not overflowing, not blocked, and the dirt collection component is in normal position, then the cleaning process is entered: The control module first sends an opening signal to the sealing valve (3) to make the sealing valve (3) open, so that the dirt and flushing wastewater in the dirt collection guide (2) can flow smoothly into the dirt collection part (4); then, the control module accurately controls the opening of the solenoid valve (7) of the corresponding area according to the dirt position fed back by the first state detection unit (9), and starts the high-pressure flushing unit (6) at the same time. The high-pressure flushing unit (6) pressurizes the cleaning water in the water storage component (5) and delivers it to the spray head (8) of the corresponding position through the opened solenoid valve (7). The spray head (8) performs single-sided / directional high-pressure flushing on the dirt area of ​​the dirt collection guide (2). The solenoid valve (7) of the non-dirty area remains closed to avoid ineffective flushing.

[0016] S4: During the rinsing process, the first state detection unit (9) continuously detects the dirt removal status of the dirt collection guide section (2). When it is detected that the dirt has been completely removed, it sends a feedback signal to the control module. The control module sends a shut-off signal to the high-pressure flushing unit (6) to stop the high-pressure water supply. At the same time, the control module controls the solenoid valve (7) of the corresponding area to close to avoid water waste. Subsequently, the control module delays for a preset time (the preset time is 10-30 seconds, which can be adjusted according to the actual structure and flow rate to ensure that the residual wastewater and dirt in the dirt collection guide section (2) completely flow into the dirt collection section (4)) and then sends a shut-off signal to the sealing valve (3) to close the sealing valve (3) to prevent the odor and dirt in the dirt collection section (4) from overflowing back into the dirt collection guide section (2).

[0017] S5: If the control module determines any of the following abnormal situations, it will prohibit the start of any flushing process and issue a prompt signal (such as light or sound prompt) to remind the user to handle the situation: ① The first state detection unit (9) does not detect dirt in the sludge collection guide section (2); ② The second state detection unit (10) detects that the sludge collection section (4) is in an overflowing state; ③ The second state detection unit (10) detects that the sludge collection section (4) is blocked; ④ The second state detection unit (10) does not detect that the sludge collection tank drain pipe is in place.

[0018] S6: When the waste collection unit (4) is a detachable waste collection bucket, the user can disassemble the waste collection bucket and empty the waste and clean the waste collection bucket according to the overflow or blockage prompt of the second state detection unit (10); after cleaning, the waste collection bucket is reinstalled in place. After the second state detection unit (10) detects that the waste collection bucket is in place and is not overflowing or blocked, it sends a signal to the control module, and the device returns to normal standby state, waiting for the next cleaning instruction; when the waste collection unit (4) is a drain pipe, the user can check whether the drain pipe is unobstructed according to the prompt signal to ensure that the waste can be discharged smoothly and avoid blockage.

[0019] S7: After cleaning is completed, the device automatically enters standby mode. The first state detection unit (9) and the second state detection unit (10) maintain low power consumption and real-time detection. When dirt is detected again in the dirt collection guide part (2) and the dirt collection part (4) is in normal condition, the above steps S3-S4 are repeated to achieve automatic cyclic cleaning.
