Embodiment 1

[0058] Example 1: Please refer to Figures 1 to 10 , The embodiment of the present invention provides a direct-flow pump, including: a cavity assembly 1, a movable assembly 21, an inflow channel 17, and a one-way valve.

[0059]The cavity assembly 1 has a built-in cavity, and an opening 5 and an outlet 22 communicating with the cavity. The movable component 21 is movably located at the opening 5 to divide the chamber into a compression chamber 3 and a movable chamber 4 . The inflow channel 17 passes through the movable assembly 21 and communicates with the compression chamber 3 . The one-way valve is configured in the inlet channel 17 . External fluid can enter the compression chamber 3 through the inflow channel 17 , and the movable component 21 is configured to compress the fluid in the compression chamber 3 so that the fluid can flow out from the outlet 22 .

[0060] Specifically, the movable assembly 21 can move from the compression chamber 3 to the movable chamber 4 to...

Embodiment 2

[0097] Example 2: Please refer to Figures 1 to 10, the embodiment of the present invention provides a sealing structure of a straight-flow pump, which can be applied to the straight-flow pump as described in the first embodiment.

[0098] The sealing structure includes: a cavity component 1 , a movable component 21 , and an inflow channel 17 . The chamber assembly 1 includes a first chamber 24 , a second chamber 26 , and a sealing ring 258 . The first cavity 24 has a cavity, and an opening 5 and an outlet 22 communicating with the cavity. The second cavity 26 is embedded in the opening 5 , and a sealing groove on a side wall of the cavity is formed between the second cavity 24 and the first cavity 24 . The sealing ring 258 is disposed in the sealing groove. The movable component 21 can move through the second cavity 26 to divide the cavity into a compression chamber 3 and a movable chamber 4 . The movable component 21 is configured to compress the fluid in the compression...

Embodiment 3

[0128] Example 3: Please refer to Figures 1 to 10 , the embodiment of the present invention provides a driving structure of a DC pump, which can be applied to the DC pump as described in Embodiment 1.

[0129] The driving structure includes: a cavity assembly 1 , a movable assembly 21 , and a driving assembly 19 . The cavity assembly 1 has a built-in cavity, and an opening 5 and an outlet 22 communicating with the cavity. The movable component 21 is movable at the opening 5 and is used to divide the chamber into a compression chamber 3 and a movable chamber 4 . The movable component 21 is configured to compress the fluid in the compression chamber 3 so that the fluid can flow out from the outlet 22 . The driving assembly 19 is connected to the movable assembly 21 through transmission. The driving assembly 19 includes a driving gear 9 sleeved on the movable assembly 21 . One of the driving gear 9 and the movable assembly 21 has a first protrusion 11 , and the other has a f...

Abstract

The invention provides a driving structure of a straight-flow pump, and relates to the technical field of pumps. The driving structure comprises a cavity assembly, a movable assembly and a driving assembly, wherein the cavity assembly is internally provided with a containing cavity and communicates with an opening and an outlet of the containing cavity; the movable assembly is movably located at the opening and used for dividing the containing cavity into a compression chamber and a movable chamber; and the driving assembly is in transmission connection with the movable assembly. The driving assembly comprises a driving gear arranged on the movable assembly in a sleeving mode. One of the driving gear and the movable assembly is provided with a first protrusion, and the other of the drivinggear and the movable assembly is provided with a matching part matched with the first protrusion. The driving gear can rotate relative to the movable assembly so that the first protrusion can slide on the matching part and drive the movable assembly to compress the compression chamber. The driving gear is arranged on the movable assembly in a sleeving mode, and when the driving gear rotates, thefirst protrusion and the matching part do circular motion relatively; and when the driving gear drives the movable assembly to compress the compression chamber, the eccentric effect cannot be generated, and vibration and noise can be greatly reduced.

Description

technical field [0001] The invention relates to the field of pumps, in particular to a driving structure of a direct current pump. Background technique [0002] With the development of technology, water equipment such as dental flossers and water dispensers are used in people's lives, bringing great convenience to people's lives. These water equipment all need to install water pumps, among which, piston pumps are more commonly used. [0003] The driving method of the traditional transmission piston pump is to drive the eccentric wheel to rotate through the motor. The eccentric wheel drives the piston to move through the crank to drive the fluid in the compression chamber to be ejected from the outlet. Due to the structural characteristics of the eccentric wheel, this structure will inevitably cause relatively large vibrations, accompanied by relatively large noises, and poor user experience. Contents of the invention [0004] The invention provides a driving structure o...
