[0030] Specifically, the cold water inlet 4 and the hot water inlet 5 are respectively located on the front side of the heat exchange device 3, which is convenient for users to connect to the water source. The design of the two filter plates 6 cleverly achieves the effect of reducing the entry of solid particles into the device, effectively protecting the normal operation of subsequent processing equipment. In order to ensure the continuous and effective operation of the filter plate 6, the filter plate 6 needs to be cleaned regularly. The device drives the threaded rod 8 through the servo motor 7, so that under the restriction of the slider 12 and the slide groove 13, the cleaning shell 9 will not rotate with the threaded rod 8, but will move along the axis of the threaded rod 8. In this process, under the elastic force of the two return springs 10, the cleaning scraper 11 completes the cleaning of the two filter plates 6. In this way, larger particles can be cleaned up in time, thereby realizing automatic cleaning of the filter plate. The device can realize the automation of the entire cleaning process, greatly reducing the labor cost.

[0031] Reference Figure 1 and Figure 3 The disassembly mechanism 2 includes two connecting shells 201, and the adjacent sides of the two connecting shells 201 are fixedly connected to the left and right sides of the top shell 1.

The left and right ends of the front sides of the two movable plates 205 are provided with clamping grooves 206. The bottoms of the two clamping plates 202 are respectively clamped with the corresponding clamping grooves 206.

[0032] Specifically, by starting the two electric telescopic rods 204, the movable plate 205 begins to move, and the movement of the movable plate 205 causes the engaging plate 202 to gradually separate from the corresponding engaging groove 206. As the engaging plate 202 separates from the engaging groove 206, the top shell 1 is pulled, so that the two connecting shells 201 and the two fixed shells 203 are separated, and then the two shells 1 are disassembled. This disassembly scheme not only reduces the time required for maintenance and disassembly, but also improves the efficiency of maintenance work.

[0034] Specifically, through the control switch 19 electrically connected to the heat exchange device 3, the electric telescopic rod 204 and the servo motor 7 respectively, the control switch 19 can complete the opening and closing of the device, and the tops of the two sealing plates 14 are respectively engaged with the corresponding sealing grooves 15, so that the sealing of the two outer shells 1 can be effectively increased. The protective shell 20 can protect the control switch 19 and prevent accidental touch.

[0036] Specifically, the bottom ends of the two connecting columns 16 are respectively engaged with the corresponding holes 17, so that the connection effect of the two shells 1 is improved, the blocking plate 18 is used to prevent the cleaning shell 9 from excessive displacement and damaging the servo motor 7, and the two sealing rings 21 can increase the sealing performance of the cold water inlet 4 and the hot water inlet 5 of the pipeline.

[0037] Working principle: When it is used at the beginning, the cold water inlet 4 and the hot water inlet 5 can be connected respectively through the two connecting ports on the front side of the bottom shell 1, and the two filter plates 6 can be used to reduce the effect of solid particles entering the inside of the device.
