Breast pump and transmission mechanism and transmission method thereof

Abstract

The invention provides a breast pump and a transmission mechanism and a transmission method.The transmission mechanism is used for transmission between a motor and a screw of a piston pump and comprises a driving gear set and a driven gear set, the driving gear set is connected with the motor, and the driven gear set is connected with the screw of the piston pump; the driving gear set and the driven gear set are in transmission through a synchronous belt. By means of the characteristics of flexibility and long-distance transmission of the belt, noise generated during direct transmission between the gears can be reduced, transmission can be carried out at the positions far away from the gears, large-size gears do not need to be arranged, and therefore less space is occupied, and remarkable advantages are achieved.

Description

technical field [0001] The invention belongs to the technical field of breast pumps, and in particular relates to a breast pump and its transmission mechanism and transmission method. Background technique [0002] With the continuous improvement of living standards and the continuous enhancement of people's health awareness, most mothers use electric breast pumps for breastfeeding. At present, most of the breast pumps on the market use diaphragm pumps, but due to the working mode of the diaphragm pump, there will be a lot of noise, and the suction power is low in the high-frequency pumping and lactation working modes, and the efficiency of breast pumping and lactation is low. [0003] In addition, a small number of breast pumps on the market use piston pumps, but the transmission of the transmission mechanism either adopts spur gears, and the noise between the gears is relatively large when the transmission mechanism is running; Considering factors such as manufacturing cos...

AI Technical Summary

Problems solved by technology

At present, most breast pumps on the market use a diaphragm pump, but due to the working method of the diaphragm pump, it will generate a lot of noise, and the suction force is low in the high-frequency breast pumping and lactation mode, and the efficiency of breast pumping and lactation is low.

[0003] In addition, a small number of breast pumps on the market use piston pumps, but the transmission of the transmission mechanism either uses spur gears, and the noise between the gears is relatively large when the transmission mechanism is running; or the gears with fewer segments are used. Considering factors such as manufacturing cost and beautiful volume, in the limited space inside the breast pump shell, the size of the transmission gear of the piston pump cannot be made too large, and it is difficult to achieve the best suction force of the piston pump
