Embodiment

[0024] Example: such as Figure 1-5 As shown, the present invention discloses a first embodiment of a liquid pump, which includes a motor 100 , a transmission structure 200 connected to the output of the motor 100 , and a pump body 300 matched with the output of the transmission structure 200 .

[0025] The motor 100 includes an output gear 110 located on the output shaft of the motor, and the motor 100 is preferably a DC brushed or brushless motor. The direction of the output shaft of the motor is perpendicular to the movement direction of the pump core 330 . The motor 100 is provided with a motor fixing frame 120 matched with the transmission structure 200 .

[0026] The transmission structure 200 includes a gear box 204 fixedly connected with the motor fixing frame 120, a gear box cover 206 tightly fitted with the gear box 204, a primary gear 210 accommodated by the gear box 204 and meshed with the output gear 110, The secondary gear 220 housed in 204 and meshed with the ...

Abstract

The invention discloses a liquid pump and an electric appliance. The liquid pump comprises a motor, a transmission structure in transmission connection with the output of the motor, and a pump body matched with the output of the transmission structure, wherein the pump body comprises a water inlet, a water outlet, a pump cavity communicating with the water inlet and the water outlet, and a pump core controlled by the output of the transmission structure, and the pump core is provided with a pump core cavity which communicates with the pump cavity and is variable in capacity. The liquid pump islarge in flow and low in flow speed, full-time liquid storage and no leakage of the pump cavity are achieved, when the pump core of the liquid pump is accidentally damaged due to long-term fatigue orother reasons, the anti-leakage reliability of the liquid pump is greatly improved, and meanwhile the service life of the liquid pump is prolonged.

Description

technical field [0001] The invention relates to a liquid pump and an electric appliance. Background technique [0002] A liquid pump is a machine used to transport or pressurize a liquid. It transmits the mechanical energy of the motor 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, etc. Household, automotive, marine, aerospace and other appliances require a wide variety of liquid pumps. However, the sealing structure is an important part of the liquid pump. When the pump core of the liquid pump is accidentally damaged due to long-term fatigue or other reasons, the entire liquid pump will fail. Contents of the invention [0003] The purpose of the present invention is to provide a liquid pump and an electrical appliance with high flow rate and low flow rate to realize full-time liquid storage in the pump chamber without leakage. The function of preventing leakage of...
