[0036] Embodiment

[0037] Figure 1 It is the front view of the control box in the embodiment of the present invention; Figure 2 It is the schematic diagram of installing the control box on the pump in the embodiment of the present invention. The pump 200 is a machine for transporting fluids or increasing the pressure of fluids. As Figure 2 shown, generally, the pump 200 includes a pump body 210 and a driving motor (not shown in the figure), and the driving motor (not shown in the figure) can be installed in the casing 220. In addition, a control box 100 is provided for the driving motor to control the operation of the driving motor (not shown in the figure). Further, the control box 100 can be integrally installed on the casing 220. Generally, an interface for outlet transfer needs to be provided on the control box 100 for connecting the signal line or power line led out by the client. Among them, the client is used to send control signals or power supply to the control box 100 to control the operation of the driving motor (not shown in the figure). A control box 100 proposed in this embodiment is applicable to optimizing the situation of the occupied space of the control box 100.

[0038] Figure 3 It is the side view of the pump installed with the control box in the embodiment of the present invention; Figure 4 It is the cross-sectional schematic diagram of the pump installed with the control box in the embodiment of the present invention.

[0039] Refer to Figures 1-4 The control box 100 includes: a box body 110 and a box cover 120. Among them, the box cover 120 is matched with the box body 110 and is covered on the box body 110.

[0040] Refer to Figure 1The box body 110 and the box cover 120 both include a first portion 111 and a second portion 112; wherein the first portion 111 of the box body 110 corresponds to the first portion 111 of the box cover, and the second portion 112 of the box body 110 corresponds to the second portion 112 of the box cover.

[0041] The first portion 111 and the second portion 112 are in terms of relative positions. In fact, the first portion 111 and the second portion 112 may be integrally formed.

[0042] Further, the first part 111 of the control box 100 is disposed on an end of the housing 220 of the pump 200 that is axially away from the pump body 210, and is matched with the end. For example, the first part 111 of the box body 110 is detachably mounted on the end, so that the first part 111 of the control box 100 is detachably mounted on the end.

[0043] The second portion 112 of the control box 100 is formed by extending the first portion 111 of the control box 100 radially outwardly along the housing 220. Figure 4 A space is formed between the second portion 112 of the control box 100 and the pump body 210, so that the control box 100 can fully utilize the space at the axial end of the casing 220 and the periphery of the end, realize the reasonable use of the narrow space, and improve the adaptability of the control box 100 to the use environment with strict space requirements.

[0044] In one embodiment, referring to Figures 1-2 The first part 111 of the box body 110 is connected to the axial end of the housing 220 by a plurality of screws 3. Further, the box body 110 and the box cover 120 of the control box 100 are both provided with avoidance structures corresponding to the screws 3. Optionally, the avoidance structure is an avoidance groove.

[0045] As in a specific embodiment, reference Figures 1-3 , the size of the end of the housing 220 is a square surrounded by four R160s, and the first part 111 of the box body 110 can be arranged within the square to avoid the nut 4 fixing the housing 220 and the pump body 210. Further, the first part 111 of the box body 110 is connected to the housing 220 by screws 3, and the first part 111 of the box body 110 is also provided with an avoidance structure for avoiding the screw 3, such as an avoidance groove, and the second part 112 can extend radially outward along the housing 220 between adjacent avoidance structures (such as avoidance grooves). For example, the second part 112 is similar to a vertical part along the radial direction of the housing 220. Figure 3 The axis 5 shown in the figure is extended, and its width can be less than or equal to the distance between two adjacent screws 3. Its extended length is determined by the diameter length D of the end of the housing 220 and the width of the outlet adapter module 6.

[0046] During use, the control box 100 can be installed on the housing 220 as a whole as a unit, so that the control box 100 and the pump 200 can be installed separately as a module and then assembled together to facilitate production arrangements.

[0049] 2. It is easy to install and disassemble, which will not cause unnecessary damage or destruction to parts and reduces costs;

[0050] 3. Modular design improves the efficiency of mass production.

[0051] Based on the above technical solution, Figures 2-4 , a line adapter module 6 is detachably mounted on the casing 220; an opening 130 can be provided on the second portion 112 of the box body 110 on a side facing the pump body 210; when the first portion 111 of the box body 110 is mounted at the end, the line adapter module 6 can be inserted into the opening 130, and further, the line adapter module 6 is used to detachably mount a wiring plug 7 along the axial direction of the casing 220, so that the wiring plug 7 is placed in the empty position 8.

[0052] Further, see Figure 4 A receiving cavity is formed between the box cover 120 and the box body 110, and a control module 140 is installed in the receiving cavity;

[0053] The control module 140 is provided with an electrical contact point on one side facing the opening 130 , and the electrical contact point is provided corresponding to the opening 130 ; when the outlet adapter module 6 is placed in the opening 130 and the wiring plug 7 is inserted into the outlet adapter module 6 , the wiring plug 7 is electrically connected to the electrical contact point.

[0054] The control module 140 may be a circuit board provided with electrical contacts. The electrical contacts may be conductive springs provided on the circuit board, and the wiring plug 7 may be point-connected to the springs through a transfer component (not shown) on the outlet transfer module 6. The transfer component (not shown) may be a power pin or a signal pin.

[0055] Optional, see Figures 1-3, on the side of the control module 140 facing away from the opening 130, an indicating component 151 is provided, such as an indicator light; on the first part 111 of the box cover 120, a display panel 150 is provided, and a transparent area is provided on the display panel 150 for displaying the indicating component 151. The transparent area can be a hole opened on the display panel 150, and a transparent mylar is filled in the hole or pasted on the hole. Mylar (zdPET) is a milky white or light yellow, highly crystalline polymer with a smooth and shiny surface.

[0056] On the basis of the above technical solution, referring to Figure 4 , the box body 110 and the box cover 120 are detachably connected. Optionally, the box body 110 and the box cover 120 are connected by screws 9, and a waterproof component 10, such as a leather plug, is provided above the screws 9, which can well play the roles of ornament, waterproofing and covering the screws 9.
