[0030] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0031] like Figure 1-5 As shown, this utility model provides a controller testing water circulation device for an electronic water pump, the device comprising: a testing mechanism assembled in a testing cabinet;

[0032] The testing mechanism includes: a water tank 1 containing a fixed amount of water, a transparent water pipe 2, and several electronic water pumps 5; wherein,

[0033] A row of water inlets 10 and a row of water outlets 11 are fixedly and horizontally arranged on the side wall of the water tank 1. Each water inlet 10 and each water outlet 11 is fixedly provided with a water pipe 2. Each water pipe 2 is detachably fixedly provided with a connector assembly 3 for threaded connection with the input or output end of the electronic water pump 5. The electronic water pump 5, which is connected to the water pipe 2 on any one of the water inlets 10 and any one of the water outlets 11 on the water tank 1, is connected to the controller 6 to be tested via a wire.

[0034] In the above scheme, multiple controllers 6 can be tested simultaneously, or a single controller 6 can be tested to determine whether the manufactured controller 6 is qualified. During the testing process, the device also includes a power supply for providing power to the controller 6 under test and the electronic water pump 5. The controller 6 and the electronic water pump 5 are connected to the power supply via power cords. Both the connection of the controller 6 and the electronic water pump 5 via wires (data cables) and the connection of the power supply to the controller 6 and the electronic water pump 5 via separate wires are existing and known connection methods.

[0035] In use, the input end of at least one qualified electronic water pump 5 is fixedly connected to the water pipe 2 on any one of the outlet ends 11 of the water tank 1 via the connector assembly 3, and its output end is fixedly connected to the water pipe 2 on any one of the inlet ends 10 of the water tank 1 via the connector assembly 3. The wire connector of the electronic water pump 5 is plugged into the interface of the controller 6 to be tested, and the power is turned on. The flow of water in the two water pipes 2 connected to the electronic water pump 5 is observed to determine whether the controller 6 to be tested is qualified. If water flows in the water pipes 2, the controller 6 to be tested is qualified; otherwise, it is unqualified. This process allows the testing mechanism to screen out qualified controllers 6.

[0036] In addition, during the testing process, the water in water tank 1 can circulate back into its interior, thus avoiding water waste. The structure is simple and the operating cost is low.

[0037] In summary, this utility model enables batch testing of multiple controllers 6 through a testing institution, thereby screening out qualified controllers 6 and improving testing efficiency. During the testing process, water can be recycled to avoid wasting water resources.

[0038] In a preferred embodiment of this utility model, each of the connector components 3 includes: a connecting seat 301, a reducing threaded sleeve 302, and a locking sleeve 303; wherein,

[0039] One end of the connecting seat 301 is coaxially and fixedly provided with a variable diameter threaded sleeve 302 with a gradually increasing inner diameter. The inner wall of the variable diameter threaded sleeve 302 is provided with an internal thread that is adapted to the output end and input end of the electronic water pump 5. The outer wall of the other end of the connecting seat 301 is coaxially and threadedly fixedly provided with a locking sleeve 303 with a gradually decreasing inner diameter that can abut against the water pipe 2. The diameter of the end portion of the connecting seat 301 located in the locking sleeve 303 gradually decreases, so that the end of the water pipe 2 can be fitted into the end of the connecting seat 301 to support the interior of the water pipe 2.

[0040] In the above scheme, such as Figure 4As shown, the variable diameter threaded sleeve 302 has a pagoda-shaped structure. In use, since the outer walls of the input and output ends of the existing electronic water pumps are provided with external threads, the variable diameter threaded sleeve 303 can be connected to electronic water pumps of different sizes.

[0041] The specific operation process is as follows: First, rotate the reducing screw sleeve 302 on the clamp assembly 3 to screw it onto the output or input end of the electronic water pump 5. Then, put the water pipe 2 on the inlet end 10 or outlet end 11 onto the other end of the connecting seat 301 on the connector assembly 3 to support the water pipe 2. Then, rotate the locking sleeve 303 to move it away from the reducing screw sleeve 302 and towards the water pipe 2 so that the inner wall of the locking sleeve 303 abuts against the water pipe 2 to lock and fix the water pipe 2, preventing the water pipe 2 from coming off the connecting seat 301 of the connector assembly 3, thereby improving the stability and reliability of the connection between the water pipe and the electronic water pump 5.

[0042] In addition, the connector assembly 3 can connect electric water pumps 5 of different sizes and water pipes 2 of different sizes, improving the flexibility and practicality of use.

[0043] In a preferred embodiment of this utility model, a sealing sleeve 7 is coaxially fixedly provided on the inner wall of the locking sleeve 303.

[0044] In the above scheme, the sealing sleeve 7 is made of rubber to improve the sealing between the variable diameter locking sleeve 303 and the water pipe 2, and to prevent water from overflowing between the variable diameter locking sleeve 303 and the water pipe 2.

[0045] In a preferred embodiment of this utility model, a ball valve 4 is fixedly installed on each of the water pipes 2.

[0046] In the above scheme, during the testing process, the No. 1 ball valve 4 on each unused water pipe 2 is closed to isolate the water pipe 2 from the water tank 1 and prevent the water in the water tank 1 from flowing out of the water pipe 2.

[0047] In a preferred embodiment of the present invention, the upper end of the water tank 1 is provided with a water inlet communicating with its interior, and the water inlet is provided with a detachable sealing cap that can be closed on it.

[0048] In the above scheme, it is convenient to add water to the water tank 1 through the water inlet.

[0049] In a preferred embodiment of this utility model, a drain pipe 8 is horizontally fixedly installed on the water tank 1 located below the row of water outlets 11, and a second ball valve 9 is fixedly installed on the drain pipe 8.

[0050] In the above scheme, during the test, the No. 2 ball valve 9 on the drain pipe 8 is closed to prevent water in the water tank 1 from being discharged from the drain pipe 8. After the test is completed, the No. 2 ball valve 9 is opened, and water in the water tank 1 can be discharged through the drain pipe 8.

[0051] In summary, the controller testing water circulation device for electronic water pumps provided by this utility model overcomes the problems of complex structure of existing testing devices and the fact that only one controller can be tested at a time during the testing process, which reduces work efficiency.

[0052] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0053] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0054] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
