[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] The utility model will be further described below in conjunction with the accompanying drawings of the specification.

[0019] The utility model provides the following technical solutions:

[0020] As attached Figure 1-3As shown, the utility model discloses a water pump casing with a water-proof structure, including a casing body 1, a stator mounting groove 2 formed in the casing body 1, and a water-proof portion 3 formed by extending from the bottom edge of the casing body 1 toward the assembly direction of the stator mounting groove 2. The water-proof portion 3 is integrally formed with the casing body 1, and a stator mounting column 4 is protruded from the water-proof portion 3. Specifically, in the present design, by arranging the water-proof portion 3 on the casing body 1, the water-proof portion 3 and the casing body 1 are an integrally formed structure. Compared with the prior art that the water-proof sleeve can be connected to the casing by screws, and a sealing ring needs to be installed for sealing, the present design forms a whole, integrated injection molding, and eliminates the sealing ring, so that the assembly is simple and the operation is simple, and no complicated assembly operation is required, which saves costs, reduces working hours, and avoids the problem of water leakage caused by the failure of the sealing ring.

[0021] Further, a stator winding 5 is arranged in the stator mounting groove 2, and the stator winding 5 is sleeved on the stator mounting column 4 on the water-blocking part 3. A plurality of positioning reinforcement ribs 6 and a card slot part 7 are protruded on the inner wall of the stator mounting groove 2, and the positioning reinforcement ribs 6 and the card slot part 7 are arranged at intervals, and the positioning reinforcement ribs 6 and the card slot part 7 are both connected to the stator winding 5. Specifically, in this embodiment, in order to prevent the stator winding 5 from rotating in the stator mounting cavity, resulting in unstable operation of the water pump, positioning reinforcement ribs 6 and card slot parts 7 are arranged. These positioning reinforcement ribs 6 and card slot parts 7 not only play a role in fixing the stator winding 5, but also increase the structural strength of the stator mounting groove 2 and improve the durability of the water pump housing. During the assembly process, the stator winding 5 is first sleeved on the stator mounting column 4 on the water-blocking part 3, and then the positioning reinforcement ribs 6 and the card slot part 7 cooperate to ensure that the stator winding 5 is stably fixed in the stator mounting groove 2. Such a design enables the stator winding 5 to maintain a stable position during the operation of the water pump, avoiding noise and vibration caused by the rotation of the winding, and ensuring the stability and reliability of the water pump.

[0022] Furthermore, the positioning reinforcement rib 6 has an arcuate surface 8 connected to the stator winding 5, and an outer limiting groove 9 is provided on the stator winding 5. One end of the positioning reinforcement rib 6 having the arcuate surface 8 extends into the outer limiting groove 9 and is connected to the stator winding 5. Specifically, in this embodiment, the arcuate surface 8 of the positioning reinforcement rib 6 is designed to make it more closely contacted with the stator winding 5, increase the contact area, and thus improve the fixing effect. The outer limiting groove 9 on the stator winding 5 provides space for the positioning reinforcement rib 6 to extend, so that the two can better cooperate to achieve a stable installation of the stator winding 5.

[0023] Furthermore, the top of the slot portion 7 is sunken near the side of the stator mounting column 4 to form a slot 10, and one end of the stator winding 5 extends into the slot 10 and is riveted to the slot portion 7. Specifically, in the present embodiment, the slot 10 of the slot portion 7 is designed to further fix the stator winding 5 to prevent it from shifting or falling off during operation. By extending one end of the stator winding 5 into the slot 10 and riveting it to the slot portion 7, a firm connection between the stator winding 5 and the water pump housing can be achieved. This connection method is not only simple and reliable, but also can effectively resist the vibration and impact force generated during the operation of the water pump, thereby ensuring the stable operation of the water pump.

[0024] Furthermore, a plurality of water-isolating reinforcement ribs 11 are formed on the water-isolating portion 3, and the water-isolating reinforcement ribs 11 extend from one end of the water-isolating portion 3 away from the central axis of the stator mounting column 4 toward the top center of the stator mounting column 4. An inner limiting groove 12 is provided on the side of the stator winding 5 close to the stator mounting column 4 corresponding to the water-isolating reinforcement ribs 11, and the water-isolating reinforcement ribs 11 extend into the inner limiting groove 12 to connect with the stator winding 5. Specifically, in the present embodiment, the design of the water-isolating reinforcement ribs 11 not only enhances the structural strength of the water-isolating portion 3, but also further improves the fixing effect of the stator winding 5. These water-isolating reinforcement ribs 11 extend from one end of the water-isolating portion 3 away from the central axis of the stator mounting column 4 toward the top center of the stator mounting column 4, and match the inner limiting groove 12 on the stator winding 5, so that the stator winding 5 is more stable and reliable when fixed. Through the cooperation between the water-isolating reinforcement rib 11 and the inner limiting groove 12, the stator winding 5 can maintain a stable position when subjected to vibration and impact during the operation of the water pump, thereby avoiding the rotation of the stator winding 5.

[0025] Furthermore, the top edge of the shell body 1 is sunken to form a sealing ring groove 13. Specifically, in this embodiment, the sealing ring groove 13 formed by the top edge of the shell body 1 can effectively improve the sealing performance of the water pump shell when the shell body 1 is press-fitted with other structures. The sealing ring groove 13 can be closely matched with the sealing ring to prevent water or other liquids from penetrating from the top edge of the shell, thereby ensuring the dryness and cleanliness of the inside of the water pump. This design not only improves the service life of the water pump, but also reduces the failure and maintenance costs caused by liquid penetration.

[0026] Furthermore, the height of the positioning reinforcement rib 6 is higher than the height of the slot portion 7. Specifically, in this embodiment, the height of the positioning reinforcement rib 6 is higher than the slot portion 7, so that the stator winding 5 is easier to be positioned and fixed during the assembly process. The height advantage of the positioning reinforcement rib 6 enables it to better support and fix the stator winding 5 to prevent it from shaking or shifting during the installation process. The slot portion 7 is mainly responsible for riveting and fixing with one end of the stator winding 5 to ensure the stability of the stator winding 5 during operation.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
