[0013] Compared with the prior art, the water pump shell structure has the following advantages:

[0014] 1. The water inlet elbow for water inlet, the water outlet pipe for water outlet, and the protruding column for positioning are integrally formed on the pump shell, which can effectively reduce the number of parts for converting the water inlet direction under the premise of ensuring the normal operation of the water pump, thereby greatly reducing the overall length of the water pump, reducing the space occupation, and facilitating assembly.

[0019] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0020] like Figure 1 As shown, the pump casing structure of this water pump includes a pump casing body 1. The front and top sides of the pump casing body 1 are respectively provided with an inlet and an outlet. The pump casing body 1 has an integrally formed inlet bend 2 at the inlet and an integrally formed outlet pipe 3 at the outlet. The inlet of the inlet bend 2 and the outlet of the outlet pipe 3 are respectively set downward and upward.

[0021] Specifically

[0022] like Figure 1 and Figure 2 As shown, the pump casing body 1 has two integrally formed protrusions 4 on its front side, and the outlet pipe 3 also has an integrally formed protrusion 4 on its front side. All three protrusions 4 are horizontally arranged and are arranged in an isosceles triangle around the central axis of the inlet. Each protrusion 4 has a horizontally formed threaded hole 4a on its front end face.

[0023] The water inlet bend 2 for water intake, the water outlet pipe 3 for drainage, and the positioning protrusion 4 are integrally formed on the pump casing. Under the premise of ensuring the normal operation of the water pump, the number of parts used to change the water intake direction can be effectively reduced. This not only greatly reduces the overall length of the water pump and reduces space occupation, but also facilitates assembly.

[0024] To further explain, a straight connecting rod 5 is provided between each pair of adjacent protruding columns 4, and the two ends of the connecting rod 5 are respectively fixed to the corresponding two protruding columns 4. The two adjacent protruding columns 4 are connected together by the connecting rod 5 to form a more stable triangular structure, which greatly enhances the overall positioning strength of the water pump and makes the water pump operate more stably.

[0025] The connection between connecting rod 5 and protruding post 4 is as follows: protruding post 4 is frustum-shaped, and its outer diameter gradually increases from front to back to provide more stable support; both ends of connecting rod 5 are arc surfaces that match the outer circumferential surface of protruding post 4, and the end faces of connecting rod 5 are attached to the corresponding outer circumferential surface of protruding post 4, and connecting rod 5 and corresponding protruding post 4 are welded together. This design facilitates the assembly of connecting rod 5 and protruding post 4.

[0026] In the actual product, each connecting rod 5 has a row of through holes 5a running horizontally through it, and the through holes 5a in the same row are evenly spaced along the length of the corresponding connecting rod 5. The design of the through holes 5a can reduce material input and reduce stress, making the water pump positioning more stable. It is preferable that the through holes 5a are round holes.

[0027] like Figure 1As shown, the upper end outer wall of the water outlet pipe 3 is formed with an annular flange 3a, and the central axis of the water outlet pipe 3 outlet and the central axis of the annular flange 3a are collinear. The protrusion 4 formed on the water outlet pipe 3 is located at the lower side of the annular flange 3a, and the upper side of the protrusion 4 formed on the water outlet pipe 3 extends to the annular flange 3a, so that the annular flange 3a and the corresponding protrusion 4 partially overlap, supporting the annular flange 3a and strengthening the strength of the annular flange 3a.

[0028] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art of the present application can make various modifications or supplements to the described specific embodiments or replace them with similar ways, but will not deviate from the spirit of the present application or exceed the scope defined by the appended claims.
