[0038] The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0039] Example

[0040] Figure 1 FIG. 2 is a schematic diagram of the overall structure of a pump in an embodiment of the present invention. The pump 200 is a machine for conveying fluid or pressurizing fluid. Figure 1As shown, generally, the pump 200 includes a pump body 210 and a drive motor (not shown), and the drive motor (not shown) can be installed in the casing 220. In addition, the drive motor (not shown) is provided with a control box 100 for controlling the operation of the drive motor (not shown). The control box 100 includes a box body 110 and a box cover 120, and the box cover 120 is covered on the box body 110. Further, the control box 100 can be installed on the casing 220 as a whole. Generally, the control box 100 also needs to be provided with an interface for output line switching, which is used to connect the signal line or power line led out from the client. Among them, the client is used to send a control signal or power supply to the control box 100 to control the operation of the drive motor. An output line switching module 300 proposed in this embodiment can be applied to optimize the output line switching of the control box 100.

[0041] Figure 2 It is a schematic diagram of the structure of a pump equipped with an outlet adapter module in an embodiment of the present invention. Figure 3 Schematic diagram of the overall cross-section of the pump in the embodiment of the present invention. Figure 1-Figure 3 The outgoing line adapter module 300 includes: a first connecting portion 310 and a second connecting portion 320 which are spaced apart.

[0042] The first connection portion 310 is detachably mounted on the edge of the housing 220 of the pump 200 at the end axially away from the pump body, and the second connection portion 320 is formed by the first connection portion 310 extending radially outward along the housing 220 to form a space 400 between the second connection portion 320 and the pump body 210.

[0043] The second connection part 320 is provided with an integrally formed adapter component 321, one end of which is used to connect the wiring plug 500, and the other end is used to connect the electrical contact point on the control module 140 of the pump 200. Specifically, the adapter component 321 is provided corresponding to the electrical contact point on the control module 140, and the control module 140 is used to control the drive motor (not shown). In one use mode, the adapter component 321 is used to insert the wiring plug 500 so that the wiring plug 500 is electrically connected to the electrical contact point. Moreover, the inserted wiring plug 500 is located in the empty space 400 between the second connection part 320 and the pump body 210, making full use of the space. Among them, the control module 140 can be a circuit board provided with an electrical contact point. The electrical contact point can be a conductive spring arranged on the circuit board, and the wiring plug 500 can be connected to the spring through the adapter component 321 of the adapter module 300.

[0044] Optionally, the first connection part 310 and the second connection part 320 are spaced apart and can be staggered so that the second connection part 320 is away from the pump body 210 to increase the space 400 between the second connection part 320 and the pump body 210 for easy plugging and unplugging of the wiring plug 500.

[0045] Furthermore, the first connection part 310 and the second connection part 320 are integrally formed, and a reinforcing component is disposed between the two to increase the connection stability between the first connection part 310 and the second connection part 320. Optionally, the reinforcing component may be as follows: Figure 4-Figure 5 The reinforcing rib 600 is shown.

[0046] Furthermore, the adapter component 321 on the second connecting portion 320 can be integrally injection molded and arranged corresponding to the electrical contact points on the control module 140, so that the adapter component 321 can be directly inserted into the control module 140 for installation without manually determining the correspondence accuracy between the adapter component 321 and the electrical contact points, thereby simplifying the installation process and improving accuracy.

[0047] It should be noted that the first connection part 310 , the second connection part 320 , and the adapter component 321 on the second connection part 320 can all be formed in one piece by injection molding, which simplifies the production process and facilitates mass production.

[0048] The technical solution of this embodiment, on the one hand, is to set the adapter component 321 integrally formed in the second connection part 320, which is set corresponding to the electrical contact point in the control module 140 and is used to connect the wiring plug 500, which can simplify the connection method between the adapter component 321 and the control module 140 and improve the accuracy of the connection between the adapter component 321 and the electrical contact point. On the other hand, the outlet adapter module 300 can fully utilize the empty space 400 between the second connection part 320 and the pump body 210 to set the adapter component 321 by setting the second connection part 320 as the first connection part 310 extending radially outward along the housing 220, so as to facilitate the insertion of the wiring plug 500 into the adapter component 321, thereby improving the adaptability of the use environment with strict space requirements.

[0049] Based on the above technical solution, a limiting component matching the housing 220 can be provided on the first connecting part 310 to limit the installation position of the first connecting part 310 on the housing 220, so as to facilitate, quickly and accurately install the output line adapter module 300 on the housing 220.
