Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, specifically to a water tank anti-overflow structure for a cage washing machine. Background Technology

[0002] A cage washing machine is a device that primarily cleans contaminated items such as cages by spraying high-pressure, high-temperature water jets onto them. Since it operates mainly through water rinsing, it must contain at least one water tank. Examples include a rapid cage cleaning machine disclosed in Chinese utility model patent CN201620108964.2, a petri dish cleaning machine disclosed in Chinese utility model patent CN201620195503.3, a cage cleaning machine disclosed in Chinese utility model patent CN201720412878.5, and a cage cleaning machine with a lifting door disclosed in Chinese utility model patent CN202222855910.0, etc. The existing water tanks mentioned above are all fully enclosed or semi-enclosed structures. This type of tank is extremely inconvenient for later maintenance and cleaning, failing to meet user needs. However, open-structure tanks often suffer from poor sealing and unstable water level detection, leading to frequent leaks and overflows. Therefore, further improvements are necessary.

[0018] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] See Figures 1-3 The water tank anti-overflow structure for the cage washing machine includes a water tank body 1, which is an open design and has a cover 3 on its top opening 2. The water tank body 1 is equipped with a water full stop float valve 4 that automatically shuts off the water inlet when the tank is full, a water level sensor 5 for detecting the water level in the tank, and a full water outlet that automatically drains water when the tank is full.

[0021] In this embodiment, the water tank body 1 is an open design with a top opening 2 to facilitate daily maintenance and cleaning of the interior. The water tank body 1 is equipped with a full-load automatic stop float valve 4, a water level sensor 5, and a full-load outlet. The full-load automatic stop float valve 4 automatically shuts off the water supply when the water tank body 1 is full. The water level sensor 5 detects the water level in the water tank body 1 and automatically shuts off the water supply when it is full. The full-load outlet allows water to be discharged from the tank when it is full. Thus, the full-load automatic stop float valve 4, water level sensor 5, and full-load outlet form a triple-programmed and mechanical anti-overflow combination, effectively solving the problem of frequent leaks and overflows in the open-type water tank body 1 during use, thereby improving the user experience and enhancing practicality.

[0022] 4. The height of the self-closing float valve when the water is full is the same or different. 5. The water level sensor is the same or different for the full water outlet.

[0023] In this embodiment, the heights of the self-stopping float valve 4 when the water is full, the water level sensor 5, and the full water outlet are set differently.

[0024] The water tank body 1 is provided with a water inlet, and a water inlet connector 6 is fixedly connected to the water inlet. The water-full automatic stop float valve 4 is located inside the water tank body 1 and is fixedly connected to the water inlet connector 6 by welding, bonding, snapping, or fasteners.

[0025] The water inlet is located at the top of the water tank body 1. The water inlet connector 6 is at least partially located inside the water tank body 1 and is fixedly connected to the water-full automatic stop float valve 4. The remaining part of the water inlet connector 6 is located outside the water tank body 1 and is provided with an external connection part for the water inlet connector.

[0026] In this embodiment, the water inlet connector 6, the water inlet, and the water-full automatic stop float valve 4 are fixed to each other by fasteners. The water inlet connector 6 is connected to the water inlet pipe and water pump through the water inlet connector external connection part. The water pump is electrically connected to the electric control board on the cage washing machine through the power cord. The water pump is also connected to the water supply end. The water pump supplies water from the water supply end into the water tank body 1 through the water inlet connector 6 and the water inlet under the control of the electric control board.

[0027] The main body 1 of the water tank is provided with an assembly hole, and the water level sensor 5 is fixedly installed on the assembly hole by welding, bonding, snapping or fasteners.

[0028] The assembly hole is located on the upper side wall of the water tank body 1. The electrical connection end of the water level sensor 5 is located outside the water tank body 1, and the detection end of the water level sensor 5 is located inside the water tank body 1.

[0029] In this embodiment, the water level sensor 5 is fixedly mounted on the mounting hole by fasteners. The electrical connection end of the water level sensor 5 is electrically connected to the electronic control board on the washing machine via a power cord. The detection end of the water level sensor 5 detects the water level in the main body 1 of the water tank and feeds back the detection information to the electronic control board. The specific height position of the water level sensor 5 can be determined according to the actual water usage.

[0030] The full water outlet is located on the upper side wall of the main body 1 of the water tank, and is fixedly connected to the full water outlet connector 7 by welding, bonding, snap-fitting or fasteners.

[0031] The full water level outlet connector 7 is located at least partially inside the water tank body 1, and the remaining part of the full water level outlet connector 7 is located outside the water tank body 1 and is provided with an external connection part for the outlet connector.

[0032] In this embodiment, the full water level outlet connector 7 is fixed to the full water outlet with fasteners. The full water level outlet connector 7 is connected to a water storage device (such as a water tank) through the external connection part of the outlet connector. The height of the water storage device is lower than the height of the external connection part of the outlet connector, so that the water flowing out of the full water level outlet connector 7 can flow directly to the water storage device by its own weight for the user to use for other purposes.

[0033] The float height of the self-stopping float valve 4 when full is higher than the detection end height of the water level sensor 5, and the height of the full water level outlet connector 7 is higher than the float height of the self-stopping float valve 4 when full.

[0034] Specifically, the water level sensor 5 is the first layer of overflow prevention. It is programmed and set at the lowest position of the three. The automatic stop float valve 4 when the water is full is the second layer of overflow prevention. It is mechanical and set at the middle position of the three. The full water outlet is the third layer of overflow prevention. It is mechanical and set at the highest position of the three.

[0035] The cage washing machine is equipped with an electronic control board, and a water pump is connected to the water inlet connector 6. The electronic control board is electrically connected to the water level sensor 5 and the water pump.

[0036] The working principle is as follows: The first layer of anti-overflow work is that when the water level in the main body of the water tank 1 reaches the detection end of the water level sensor 5, the water level sensor 5 will send a signal to the electronic control board. After receiving the signal, the electronic control board will issue a command to stop the water pump and stop working.

[0037] If the first layer of anti-overflow fails due to unforeseen reasons such as component damage or malfunction of the control board, and the water level in the main body 1 of the water tank continues to rise, the second layer of anti-overflow will activate. When the water level reaches the position of the float ball of the full-water automatic stop float valve 4, the float ball will rise due to the buoyancy of the water and automatically close the inlet and outlet, thereby automatically stopping the water intake.

[0038] If the second layer of anti-overflow fails due to some unforeseen reason such as component damage, and the water level in the main body of the water tank 1 continues to rise, the third layer of anti-overflow will activate. When the water level reaches the position of the full water level outlet connector 7, the water in the main body of the water tank 1 will flow out to the water storage device (such as a water tank).

[0039] In this embodiment, a positioning edge 8 is provided around the top opening 2, and a handle 9 is provided on the cover 3. The user can take the cover 3 off and put it on through the handle 9. The cover 3 can be detached and positioned on the positioning edge 8.

[0040] The above describes the preferred embodiments of this utility model, illustrating and describing its basic principles, main features, and advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made without departing from the spirit and scope of this utility model, and all such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
