[0002] A water pump is a machine that transports liquids or increases the pressure of liquids. It transfers the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals.

[0003] The water pump body is provided with an inlet pipe and an outlet pipe, which are used to connect with the water pipe and guide the water flow in and out at the same time. However, the inlet pipe and the outlet pipe are exposed to the outside and can be easily damaged by accidental bumps, resulting in water leakage, which in turn causes the water pressure in the pump body to drop, while reducing the head of the water pump. In addition, the inlet pipe and the outlet pipe of the water pump are mostly integrally formed with the body, which makes the pump body scrapped.

[0004] For example, the easy-to-clean water pump with application number 201720076238.1 includes a water pump body and a water pump cleaning mechanism. The water pump body is a volute, and water inlet and water outlet are arranged at both ends of the volute. An impeller is installed in the volute, an inlet valve is arranged at the water inlet, and an outlet valve is arranged at the water outlet. A liquid adding system is arranged next to the inlet valve, and a liquid outlet valve is arranged at the outlet valve.

[0005] The above patent closes the volute after injecting water into it, then adds detergent through the liquid adding system, starts the impeller to stir the water flow for washing, and finally discharges the sewage through the liquid discharge system. However, the water inlet and outlet pipes lack protection and are easily broken by bumps, resulting in reduced sealing of the pump body. Utility Model Content

[0024] like Figures 1 to 5 As shown, the utility model can be implemented through the following embodiments: a split protective pipe type water pump, including a pump body 1 and a motor 2, the pump body 1 is provided with a mounting portion 101 and a mounting portion 102, the mounting portion 101 is inserted with an inlet pipe 3, the mounting portion 102 is inserted with an outlet pipe 4, a protective shell 5 is installed on the pump body 1, the protective shell 5 is divided into a shell 1 501 and a shell 2 502, the shell 1 501 is provided with a water inlet hole and a semicircular hole 1 5012, the shell 2 502 is provided with a connecting hole 5021 and a semicircular hole 2 5022, the shell 1 501 is provided with a mounting groove, the semicircular hole 1 5012 and the semicircular hole 2 5022 of the shell 1 501 and the shell 2 502 are flat portions 6, a sheath 7 is installed on the mounting groove and the flat portion 6, and the sheath 7 is installed outside the water inlet pipe 3 and the water outlet pipe 4.

[0025] The protective shell 5 is provided to protect the pump body 1, and is assembled and processed by a shell 1 501 and a shell 2 502; the water inlet pipe 3 and the water outlet pipe 4 are partially buried in the mounting part 101 and the mounting part 2 102 to reduce the exposed area, thereby providing protection for the pump body 1; the water inlet hole and the semicircular hole 1 5012 opened in the shell 1 501, and the semicircular hole 2 5022 and the connecting hole 5021 opened on the shell 2 502 are convenient for exposing the connecting points of the pump body 1 and facilitating the assembly of the pump body 1; the installation of the sheath 7 is used to protect the exposed water inlet pipe 3 and the water outlet pipe 4, and prevent the water inlet pipe 3 and the water outlet pipe 4 from being damaged by impact, and the arrangement of the plane portion 6 facilitates the installation of the sheath 7 at the water outlet pipe 4.

[0026] like Figure 1As shown, a buffer layer 8 is provided in the protective shell 5, and the buffer layer 8 is made of rubber material. The buffer layer 8 is provided to facilitate the protective shell 5 to absorb the vibration transmitted by the pump body 1, and prevent the protective shell 5 and the pump body 1 from rubbing, causing wear and generating noise.

[0027] like Figures 1 to 4 As shown, the sheath 7 is provided with a fixing portion 701, and the sheath 7 is mounted on the housing 1 501 and the flat portion 6 through the fixing portion 701. The fixing portion 701 is used to mount the sheath 7 outside the protective shell 5, so as to facilitate replacement of the damaged sheath 7.

[0028] like Figure 1 , Figure 2 and Figure 5 As shown, the mounting part 101 and the mounting part 2 102 are respectively provided with a positioning plate 1011 and a positioning plate 2 1021, the positioning plate 1011 is provided with a sealing ring 10, and the positioning plate 2 1021 is provided with a sealing ring 2 10.
