[0053] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0054] like Figures 1 to 7 As shown, in this embodiment, an electrical box assembly 1 is provided, including a shell 11, an electric control board 12 and a guide structure 13, the electric control board 12 is provided with a terminal 121, and the electric control board 12 is connected below the top of the shell 11; the guide structure 13 is arranged on the outer surface of the top of the shell 11, and is suitable for guiding the fluid to a position away from the terminal 121.

[0055] The electrical box assembly 1 includes a flow guide structure 13, which guides the fluid to a position away from the terminal 121 to prevent the fluid from contacting the terminal 121, causing a short circuit in the wires or damage to the components. There is no need to coat the electrical components such as the terminal 121 with glue, which saves material costs, and the electrical components such as the terminal 121 can still be repaired later. There is no need to fully seal the entire structure, which reduces the number of parts and makes the structure compact and beautiful. Preferably, the electrical control board 12 is connected to the housing 11 by screws. Among them, Figure 3 The flow direction 3 is shown in FIG. The fluid may be water or an electrolyte or other aqueous solution or other liquid.

[0056] In this embodiment, the guide structure 13 includes a guide port 131, and the guide port 131 is arranged close to the side wall of the terminal 121 and is spaced apart from the terminal 121. The guide port 131 is staggered from the terminal 121, and the liquid guided from the guide port 131 flows away from a place far away from the terminal 121, and will not wet the terminal 121, causing a short circuit of the wire or damage to the component.

[0057] As a convertible embodiment, the flow guiding structure 13 may include two flow guiding ports 131, which are arranged oppositely on both sides of the housing 11. If a terminal 121 extends from one side of the housing 11, the flow guiding structure 13 includes a flow guiding port 131 arranged on the same side as the terminal 121, and a flow guiding port 131 arranged opposite to the flow guiding port 131, to ensure that the liquid does not flow from any side of the housing 11 to the terminal 121. If terminals 121 extend from both sides of the housing 11, flow guiding ports 131 are arranged at both ends of the housing 11, to ensure that the liquid does not flow from any side of the housing 11 to the terminal 121.

[0058] In this embodiment, the side wall of the guide opening 131 close to the terminal 121 is the first side wall, and the side wall of the guide opening 131 away from the terminal 121 is the second side wall; the first side wall of at least one of the guide openings 131 and the terminal 121 are located on the same side of the housing 11. Because the housing 11 is generally a structure with a certain width, it is easier for liquid to flow to the terminal 121 from the same side, so the first side wall of at least one of the guide openings 131 and the terminal 121 are located on the same side of the housing 11, which can ensure that the liquid will not flow to the terminal 121 from the same side. In this way, even if there is no guide opening 131 on the side of the housing 11 where the terminal 121 is not provided, the liquid will not easily flow to the terminal 121.

[0059] In this embodiment, the second side wall of at least one of the guide openings 131 and the terminal 121 are located on the same side of the housing 11 . The entire guide opening 131 and the terminal 121 are located on the same side of the housing 11 .

[0060] In this embodiment, there are two guide ports 131 , which are disposed on two opposite sides of the housing 11 to prevent liquid from flowing toward the terminal 121 from any side.

[0061] In this embodiment, a display area is provided on the top of the housing 11 to cooperate with the display device on the electric control board 12. The guide structure 13 is arranged outside the display area and is suitable for guiding the fluid in the display area.

[0062] The electrical box assembly 1 needs to be installed in a machine such as a disinfectant manufacturing machine.

There is inevitably a gap between the display panel 14 and the machine housing, and water often easily enters the interior of the housing through the gap. A display area is provided on the housing 11, and the display device on the electric control board 12 cooperates with the display panel 14 and / or the operation panel through an opening in the display area. The guide structure 13 is arranged outside the display area, and is suitable for guiding the fluid in the display area to prevent the liquid from flowing to the terminal 121 through the display area.

[0063] In this embodiment, the flow guiding structure 13 includes at least one flow guiding body, and the flow guiding body includes a first flow guiding rib 132 and a second flow guiding rib 133. The first flow guiding rib 132 is arranged outside the display area; the second flow guiding rib 133 and the first flow guiding rib 132 together form one of the side walls of the flow guiding port 131. The liquid entering from the display area is guided to a position away from the terminal 121.

[0064] In this embodiment, the first guide rib 132 extends upward from the top surface of the housing 11. The display area is separated from the housing 11 provided with the terminal 121, and the liquid cannot pass through the guide rib extending upward without power.

[0065] In this embodiment, the second flow guiding rib 133 includes a first flow guiding portion 1331 and a second flow guiding portion 1332. The first flow guiding portion 1331 is disposed at the top of the housing 11, and one end of the first flow guiding portion 1332 is connected to the first flow guiding rib 132; the second flow guiding portion 1332 is disposed at the side of the housing 11, and is connected to the other end of the first flow guiding portion 1331. After the fluid is guided by the first flow guiding portion 1331 and the second flow guiding portion 1332, it flows downward under the action of its own gravity, and will not flow back to the terminal 121 located above.

[0066] In this embodiment, the guide structure 13 includes two guide bodies, wherein the first guide rib 132 and the second guide rib 133 of one of the guide bodies form the first side wall of the guide port 131, and the first guide rib 132 and the second guide rib 133 of the other guide body form the second side wall of the guide port 131.

[0067] In this embodiment, the periphery of the display area includes a closed water retaining rib 113, and the water retaining rib 113 is arranged on the upper surface of the top of the shell 11. The first guide rib 132 is arranged outside the water retaining rib 113 and is spaced apart from the water retaining rib 113. The first guide rib 132, the water retaining rib 113 and the top of the shell 11 together form a guide groove.

[0068] The water retaining rib 113 is provided to ensure that the liquid does not flow to the electric control board 12 through the display area, and to shield the display area to ensure the display effect. A guide groove is provided, and the liquid is guided out through the guide groove.

[0069] In this embodiment, the electrical box assembly 1 further includes a display panel 14, the display panel 14 is connected to the water retaining rib 113, and the projection of the display panel 14 on the top of the housing 11 at least covers the projection of the water retaining rib 113 on the top of the housing 11, thereby preventing liquid from flowing from between the display panel 14 and the water retaining rib 113 to the main control board.

[0070] In this embodiment, the upper surface of the display panel 14 is a smooth surface, so that the liquid will not accumulate on the display panel 14 but will flow along the upper surface of the display panel 14 to the guide groove.

[0071] In this embodiment, the side of the display panel 14 includes a guide surface 141, and the guide surface 141 extends obliquely from the top to the bottom of the display panel 14, and the projection area of ​​the top of the display panel 14 on the housing 11 is smaller than the projection area of ​​the bottom of the display panel 14 on the housing 11. The liquid is guided into the guide groove through the guide surface 141, and flows out of the guide port 131 through the guide groove.

[0072] In this embodiment, the angle α between the guide surface 141 and the extended surface of the lower surface of the display panel 14 is 95°. Preferably, the angle α between the guide surface 141 and the extended surface of the lower surface of the display panel 14 satisfies 90°<α≤110°. Among them, the effect is best when α is 95°, which will not affect the user's recognition of the content on the display panel 14, will not affect the display effect, and can effectively guide the liquid on the display panel 14 to the guide structure 13.
