[0026] The present invention will be further described below with reference to specific embodiments:

[0027] A water pump reinforcement device includes a pump casing 1, a drive motor 2, and a reinforcement cover 3. The pump casing 1 has a high-pressure chamber, a low-pressure chamber, and a mixing chamber. The high-pressure chamber is connected to an outlet, and the low-pressure chamber is connected to a water inlet. An impeller 13 is installed inside the mixing chamber. The drive motor 2 is connected to one end of the pump casing 1, and the impeller 13 is connected to the rear of the motor shaft of the drive motor 2. The impeller 13 is driven to rotate by the drive motor 2 to realize the operation of the water pump. The reinforcement cover 3 is fixed to the outer wall of the pump casing 1 and abuts against the pump casing 1, and is used to limit the deformation of the pump casing 1.

[0028] Combination Figure 1-3 As shown, in this patent, the pump casing 1 is open on one side and is hemispherical in shape. An opening 12 is provided on the open side, through which a pressure tank 4 is connected. The pressure tank 4 contains a diaphragm 41, which is connected to the high-pressure chamber of the pump casing 1. The diaphragm 41 automatically adjusts the pressure in the high-pressure chamber to improve pump operation. The reinforcing cover 3 is adapted to the shape of the pump casing 1 and is fixed to the outer wall of the pump casing 1 by fasteners. Specifically, as... Figure 6 As shown, the reinforcing cover 3 includes a first ring portion 31, a second ring portion 32, and a reinforcing strip 33 connecting the first ring portion 31 and the second ring portion 32. The outer edge of the pump housing 1 is provided with a connecting boss 11, which is formed on the outer edge of the opening portion 12. The size of the first ring portion 31 is adapted to the size of the connecting boss 11 and abuts against the connecting boss 11 for connection with the connecting boss 11. The second ring portion 32 is used to be fitted onto the pump housing 1. In this patent, the second ring portion 32 is fitted onto the connection part between the pump housing 1 and the drive motor 2. At this time, the reinforcing strip 33 supports the outer wall of the pump housing 1. Through the cooperation of the reinforcing strip 33, the first ring portion 31, and the second ring portion 32, the outer wall of the pump housing 1 is supported, preventing the pump housing 1 from deforming outward, thereby reducing the occurrence of damage to the pump housing 1 and increasing the service life of the water pump.

[0029] Furthermore, a reinforcing groove 331 is provided in the reinforcing strip 33, and a plurality of reinforcing edges 332 are provided in the reinforcing groove 331. As shown in 4 and 6, the reinforcing cover 3 in this patent is made of plastic material. It is formed directly in the reinforcing strip 33 of the reinforcing cover 3 during injection molding. At the same time, the reinforcing edges 332 are formed in the reinforcing groove 331. The strength of the reinforcing strip 33 is ensured by reinforcing the edges 332. The manufacturing amount of the reinforcing cover 3 is saved by setting the reinforcing groove 331, and the injection molding of the reinforcing cover 3 is convenient.

[0030] In fact, since the water pump in this patent has a pressure tank 4, and a reinforcing ring 5 is also provided on the pressure tank 4, the reinforcing ring 5 is set on the outer edge of the pressure tank 4, and one end of the reinforcing ring 5 is located on the connecting boss 11, and is connected to it by the first fastener 111. In fact, combined with Figure 3-5 As shown, the first fastener 111 is generally a screw. The first fastener 111 passes through the reinforcing ring 5, the pressure tank 4, the connecting boss 11 and the first ring 31 in sequence to realize the assembly of the pressure tank 4 and the pump housing 1. At the same time, the reinforcing ring 5 and the reinforcing cover 3 are fixed together, making the water pump in this patent more compact and increasing the overall structural stability.

[0031] Furthermore, such as Figure 5 As shown, the reinforcing ring 5 is further provided with a pressure tank connecting groove 51 on the side facing the connecting boss 11. The pressure tank connecting groove 51 contains a second fastener 52 that connects the pressure tank 4 and the connecting boss 11. Figure 5 As shown, the second fastener 52 is generally a screw, and the pressure tank connecting groove 51 is square, which is used to leave space for the second fastener 52 to connect the pressure tank 4 and the pump housing 1, so as to further strengthen the connection between the two.

[0032] Furthermore, a motor end cover 21 is provided on one side of the drive motor 2, and a third fastener 22 connected to the reinforcing cover 3 is provided on the motor end cover 21. Figure 2 As shown, the motor end cover 21 has three threaded holes in the middle ring, and the second ring 32 of the reinforcing cover 3 has threaded holes opposite to the connecting protrusion. By setting fasteners on both, the reinforcing cover 3 and the drive motor 2 are connected, thereby increasing the overall stability of the water pump.
