As shown in fig. 13 to 14, in some embodiments of the present invention, the opening 121 is configured to be rectangular, and the first drainage parts 122 are disposed on both sides of the opening 121 in the up-down direction, so that the accumulated water at the opening 121 can be drained to the side of the opening 121 by the first drainage parts 122, and the accumulated water can flow down along the side, preventing the accumulated water from being stagnant at the opening 121.
In some alternative embodiments of the present invention, the inclined surface may be formed by a combination of a flat surface and a curved surface, and such a structure may also provide a good drainage effect.
In some embodiments of the present invention, the upper surface of the first flow inducing portion 122 is configured as a stepped surface, and the first flow inducing portion 122 has a higher height at one end of the stopper 1211 than at the other end. Such a structure allows the first drainage portion 122 to perform a good drainage function at the stop 1211, and fluid in the first drainage portion 122 can be drained to the side of the first plate portion 110, and the fluid can flow down under the action of gravity, so that the fluid is effectively prevented from being retained in the first drainage portion 122, and the risk of the fluid entering the inside of the distribution box 1000 can be reduced.
In a further embodiment of the present invention, the upper surface of the step surface may be set to a plane that is inclined from the horizontal direction, and it can be understood that when the accumulated water flows to the step surface, the accumulated water contacts with the upper surface of the step surface, and due to the inclined arrangement of the upper surface of the step surface and the accumulated water being subjected to the action of gravity, the accumulated water has a movement tendency to flow toward the lower end of the inclined surface on the inclined surface, and the step surface is not provided with a structure for blocking the flow of the accumulated water, so that the accumulated water can flow from the upper step surface to the lower step surface.
It should be noted that, the upper surfaces of the step surfaces are inclined in the same direction, and all the step surfaces are inclined from the side with the higher step position to the side with the lower step position, so that the arrangement can effectively ensure that accumulated water left from the step surface with the higher step position can flow to the step surface with the lower step position, and the accumulated water is better prevented from being retained on the step surface.
As shown in fig. 3, in some embodiments of the present invention, an annular sealing groove 112 is disposed on a rear surface of the first plate portion 110, a rear end of the sealing groove 112 is open, the sealing groove 112 accommodates the sealing strip 111 therein, the sealing groove 112 includes a first section 112a, a second section 112b, and a third section 112c, the third section 112c is connected between the first section 112a and the second section 112b, the first section 112a is located right above the second section 112b, a rear end of a lower plate of the first section 112a is provided with a first flange 114, the first flange 114 extends upward, the first section 112a is provided with a second drain 113 guiding a fluid at a rear side of the sealing strip 111, and the second drain 113 extends in a length direction of the first section 112 a.

As shown in fig. 6, in some embodiments of the present invention, the thickness of the second drain 113 decreases from above toward the other end along one end of the length direction of the second drain 113. The fluid has a tendency to move from the thicker end to the thinner end on the second flow guide 113, so that the fluid can flow on the second flow guide 113, and the fluid cannot be retained at the first plate portion 110, thereby reducing the risk of the fluid entering the inside of the distribution box 1000.
In a further embodiment of the present invention, the upper surface of the second flow guide 113 is configured as a slope having an angle with the horizontal direction, and the slope is disposed such that the fluid has a moving tendency to flow downward when it is on the second flow guide 113, so that the fluid can be effectively prevented from being stagnated at the first plate portion 110.
As shown in fig. 13 to 14, in some embodiments of the present invention, the rear portion 1211b of the lowermost stop portion 1211 is provided with a third flow guiding portion 117. When the accumulated water flows to the lowermost abutting portion 1211, the accumulated water flows out along the extending direction of the third drainage portion 117, thereby further reducing the risk of the accumulated water entering the distribution box 1000.
In some embodiments of the present invention, the rear end of the third flow guide 117 is provided with a third flange 118 extending upward, and the upper end surface of the third flange 118 is higher than the upper surface of the third flow guide 117.
