Description

Technical Field

[0001] This application relates to the technical field of water return devices, and in particular to an installation structure for a water return device. Background Technology

[0002] Water return devices are susceptible to pump leakage during use, which can easily damage the control structure (i.e., the control circuit board and display board). Patent document CN218269603U discloses a circulating water return device, which includes "by installing a sealing isolation component on the inner wall of the housing, the housing is divided into a control chamber and an execution chamber, thereby reducing the impact of water vapor on the control circuit board when the pump leaks." However, when maintenance or replacement of parts is required, especially the disassembly of the control circuit board, if the wire length between the control circuit board and the display board is short, the display board also needs to be removed. If the display board is not removed, a long connecting wire needs to be installed between the control circuit board and the display board, making the maintenance or replacement of parts of the water return device very cumbersome. Utility Model Content

[0003] To address the shortcomings of existing technologies, one of the objectives of this application is to provide an installation structure for a water return device that has an independent installation space to accommodate the control circuit board and the display board. This eliminates the need for long connecting wires when disassembling the control circuit board, regardless of whether the display board needs to be removed, thus making the maintenance or replacement of parts of the water return device more convenient.

[0004] The above-mentioned objective of this application is achieved through the following technical solution:

[0005] An installation structure for a water return device includes a housing, on which an isolation groove and a receiving cavity are provided. The receiving cavity is used to accommodate a water pump, and the isolation groove is used to isolate the control structure and the water pump.

[0006] By adopting the above technical solution, the isolation groove isolates the execution structure and the control structure, so that when disassembling the control circuit board, no long connecting wire is required, regardless of whether the display board needs to be removed, thus making the maintenance or replacement of parts of the water return device more convenient.

[0007] In a preferred embodiment, this application may be further configured to include a cover plate, which cooperates with the isolation groove to form an isolation cavity, the isolation cavity and the receiving cavity being non-communicating, the isolation cavity being used to receive the control structure.

[0008] By adopting the above technical solution, the cover plate and the isolation groove cooperate to form an isolation cavity, so that the control structure is installed in a sealed cavity. The isolation cavity and the receiving cavity are not connected, which makes the sealing effect of the isolation cavity better.

[0009] In a preferred embodiment, this application can be further configured such that: the housing is provided with a limiting groove 1 and a limiting groove 2, the limiting groove 1 and the limiting groove 2 cooperating to limit the position of the upper and lower parts of the cover plate.

[0010] By adopting the above technical solution, the installation of the cover plate becomes easier.

[0011] In a preferred embodiment, this application can be further configured such that: a connecting part is provided on the housing, and the control structure is mounted on the housing through the connecting part.

[0012] In a preferred embodiment, this application can be further configured such that: a second connecting portion is provided on the cover plate, and the housing is connected to the cover plate through the second connecting portion. Attached Figure Description

[0018] The present application will be further described in detail below with reference to the accompanying drawings.

[0019] Reference Figures 1 to 4 The present application discloses an installation structure for a water return device, comprising a housing 1 and a cover plate 2. The housing 1 includes an upper shell 11 and a lower shell 12. A screw passes through the lower shell 12 and connects to the upper shell 11. The upper shell 11 and the lower shell 12 form a receiving cavity 3, which is used to accommodate a water pump. An isolation groove 4 is provided on the upper shell 11. The isolation groove 4 and the cover plate 2 form an isolation cavity. A hole in the isolation groove 4 is used for threading cables. The isolation cavity and the receiving cavity 3 are connected before the cables are threaded. After the cables are threaded, a sealing ring is used to seal the hole, so that the isolation cavity and the receiving cavity 3 are not connected, thereby ensuring good sealing of the isolation cavity. The isolation groove 4 is used to isolate the control structure 5 and the water pump, and the isolation cavity is used to accommodate the control structure 5.

[0020] The upper shell 11 is provided with a connecting part 13, a drain hole 14, a connecting part 3 17, a limiting groove 15 and a limiting groove 2 16. The screw passes through the control structure 5 and is threadedly connected to the connecting part 13, so that the control structure 5 is installed on the upper shell 11. The lower shell 12 is threadedly connected to the connecting part 3 17 on the upper shell 11 by bolts. The drain hole 14 is used to drain the liquid remaining on the surface of the shell 1. When the shell 1 is installed horizontally outdoors (i.e., the drain hole 1 faces upward), liquid is easily accumulated on the surface of the shell 1. In this embodiment, the number of connecting parts 13 is set to four sets, the number of drain holes 14 is set to three sets, and the limiting groove 15 and the limiting groove 2 16 cooperate to limit the position of the upper and lower parts of the cover plate 2.

[0021] The cover plate 2 is provided with a connecting part 21. In this embodiment, the number of connecting parts 21 is set to four. The screw passes through the upper shell 11 and is threadedly connected to the connecting part 21, so that the upper shell 11 and the cover plate 2 are connected.

[0022] The control circuit board and display board are installed in the isolation groove 4, and the screw passes through the control circuit board and display board and is fixedly connected to the connecting part 13. The cover plate 2 is fastened on the upper shell 11. The limiting groove 15 and the limiting groove 26 limit the upper and lower parts of the cover plate 2. The screw passes through the upper shell 11 and is threadedly connected to the connecting part 21 on the cover plate 2, so that the cover plate 2 and the upper shell 11 are connected and form an isolation cavity, so that the control circuit board and display board are located in the isolation cavity. Then the upper shell 11 and the lower shell 12 are connected to complete the installation of the water return device.

[0023] When the water return device needs maintenance, the upper shell 11 and lower shell 12 can be opened directly to maintain and repair the water pump and its accessories in the receiving cavity 3. When the control circuit board or display board needs to be repaired, it can be repaired by opening the cover plate 2. In other embodiments, the second connection part 21 can be provided on the upper shell 11, and the screw passes through the cover plate 2 and is threadedly connected to the second connection part 21 on the upper shell 11, making it more convenient to repair the control circuit board or display board.

[0024] The implementation principle of this embodiment is as follows: the isolation groove 4 is located at the front of the housing 1, so that the size of the panel is not affected by the internal space of the housing 1. The isolation groove 4 isolates the execution structure and the control structure 5 (i.e., the control circuit board and the display board), so that when the control circuit board is disassembled, no long connecting wire is required, regardless of whether the display board needs to be removed, thus making the maintenance or replacement of parts of the water return device more convenient.

[0025] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
