The strip-shaped groove and the partition have the same length extension direction, and both ends of the strip-shaped groove are open. The upper end of the baffle is inserted into the above-mentioned strip-shaped groove. With the above design, the baffle and the partition partially overlap, effectively expanding the protection range.

[0012] In the casing of the above-mentioned water pump controller, the above-mentioned internally threaded pipes are arranged around the rear cover. The number of the mounting holes, the second screws, and the internally threaded pipes is the same and their positions correspond one by one. With the above design, the positioning strength and stability of the rear cover can be greatly enhanced.

[0013] In the casing of the above-mentioned water pump controller, a concave cavity is formed at the position of the bottom wall of the box body opposite to the rear cavity. A heat dissipation fan is horizontally fixed in the concave cavity, which can effectively accelerate the heat dissipation of the electronic components in the rear cavity and the entire controller, extending the service life.

[0014] In the casing of the above-mentioned water pump controller, the head of the second screw presses against the bottom wall of the concave cavity to better hide the second screw and increase the difficulty for the user to remove the rear cover.

[0015] In the housing of the above-mentioned water pump controller, the concave cavity is strip-shaped and extends longitudinally, and a row of heat sinks are vertically formed on the bottom wall of the concave cavity. The heat sinks extend longitudinally, and the row of heat sinks are arranged at intervals left and right. The heat sinks are provided to further accelerate the heat dissipation of the controller.

[0016] In the housing of the above-mentioned water pump controller, an annular groove matching the upper end of the box body is provided on the bottom wall of the box cover, and the annular groove is formed by a front groove body provided on the bottom wall of the front cover shell and a rear groove body provided on the bottom wall of the rear cover shell. The upper end of the box body is inserted into the annular groove and pressed against the bottom wall of the annular groove. With the above design, it is beneficial to assemble the front cover shell, the rear cover shell and the box body.

[0017] Compared with the prior art, the housing of the present water pump controller has the following advantages:

[0018] 1. The box cover is divided into a front cover shell and a rear cover shell that are independently installed, and the installation directions of the first screw for positioning the front cover shell and the second screw for positioning the rear cover shell are opposite. When the controller is actually installed, the bottom of the box body is facing away from the user, and the head of the second screw is arranged at the bottom of the box body, playing a hidden role and increasing the difficulty for the user to open the rear cover shell. In this way, it can be limited that the user can only open the front cover shell for operation, realizing partial opening of the housing and achieving the effect of partial access to the internal components of the housing.

[0019] 2. The baffle divides the inner cavity of the box body into a front cavity and a rear cavity, and the baffle is arranged facing the rear cover shell. In this way, during actual use, the electronic components that are inconvenient for the user to contact can be arranged in the rear cavity, playing a better protective effect.
