[0020] Embodiment: Through the personnel in this field, all the electrical components in this case are connected to their adapted power supplies through wires, and a suitable controller should be selected according to the actual situation to meet the control requirements. The specific connection and control sequence should refer to the following working principle. The electrical connection between the electrical components is completed in the working sequence. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and does not explain the electrical control. Please refer to Figure 1-3 In order to solve the problem that the circulating water vacuum pump needs to be shut down for maintenance of its refrigeration and filtration functions, which affects the normal use of the circulating water vacuum pump and causes inconvenience in use and maintenance, this technical solution is designed. The detailed technical solution is as follows;

[0021] A circulating water vacuum pump comprises a water tank 1, a buckle cover 2 is mounted on the water tank 1, a pump body 3 is mounted on the buckle cover 2, and a water storage structure is mounted on the buckle cover 2 and the water tank 1;

[0022] Specifically, the water storage structure includes a bottom tee pipe 4 and a top tee pipe 5. The bottom tee pipe 4 is installed on the buckle cover 2 and is located on one side of the pump body 3. Two cold filter components are installed between the bottom tee pipe 4 and the top tee pipe 5. A circulation component is installed on the top tee pipe 5.

[0023] It should be noted that one end of the top three-way pipe 5 is connected to the water source, and two cold filter assemblies are installed at the other two ends. After being cooled and filtered by the two cold filter assemblies, the water enters the water tank 1 through the bottom three-way pipe 4;

[0024] More specifically, the two cold filter assemblies each include a bottom valve 6, the bottom valve 6 is mounted on the bottom three-way pipe 4, a filter cartridge 7 is mounted on one end of the bottom valve 6, a filter screen 8 is mounted on the inner wall of the filter cartridge 7, a top valve 9 is mounted on one end of the filter cartridge 7, a refrigerator 10 is mounted on one end of the top valve 9, and the top three-way pipe 5 is mounted on the refrigerator 10;

[0025] It should be noted that the water entering from the top three-way pipe 5 is cooled by the refrigerator 10, then enters the filter cartridge 7 through the top valve 9, is filtered through the filter screen 8, and then enters the bottom three-way pipe 4 through the bottom valve 6. The purpose of designing two cold filter components to work at the same time is that when one of the cold filter components needs maintenance, the other cold filter component can also work without suspending the operation of the circulating water vacuum pump, thereby ensuring the normal use of the circulating water vacuum pump, facilitating use and maintenance. When maintaining the filter screen 8, close the top valve 9 and the bottom valve 6, remove the filter cartridge 7 from the top valve 9 and the bottom valve 6, and then replace the new filter cartridge 7 and the filter screen 8;

[0026] More specifically, the circulation assembly includes a check valve 11, which is installed on the top three-way pipe 5, a circulation pump 12 is installed at one end of the check valve 11, a circulation pipe 13 is installed at one end of the circulation pump 12, and the circulation pipe 13 is inserted on the side wall of the water tank 1;

[0027] It should be noted that when the pump body 3 is working, the water temperature in the water tank 1 increases due to the increase in the temperature of the pump body 3, so the circulation pump 12 is turned on, and the water in the water tank 1 enters from the circulation pipe 13, and then flows back to the top three-way pipe 5 from the check valve 11, and is filtered and cooled again through the two cold filter components to avoid high water temperature;

[0028] As a preferred embodiment, further, a temperature sensor 14 is installed on the inner wall of the water tank 1. When the temperature sensor 14 detects that the water temperature in the water tank 1 is higher than a set value, the circulation pump 12 starts working.

[0029] As a preferred embodiment, further, a liquid level sensor 15 is installed on the inner wall of the water tank 1, and a water inlet valve 16 is installed at one end of the top three-way pipe 5. When adding water, the water adding valve is opened to add water into the water tank 1. When the liquid level sensor 15 detects that the liquid level reaches the highest value of the set value, the water adding valve is closed to stop adding water. When the liquid level sensor 15 detects that the liquid level is lower than the lowest value of the set value, the water adding valve is opened again to add water into the water tank 1 again.

[0030] Preferably, further, the filter cartridge 7 is connected to the bottom valve 6 via a flange, and the filter cartridge 7 is connected to the top valve 9 via a flange, so as to facilitate the disassembly of the filter cartridge 7 .
