Description

Breast pump and transmission mechanism and transmission method thereof
Technical Field
The invention belongs to the technical field of breast pumps, and particularly relates to a breast pump and a transmission mechanism and a transmission method thereof.
Background
With the continuous improvement of living standard and the continuous enhancement of health consciousness of people, most mothers suck milk by using electric breast pumps. Most of the breast pumps on the market at present use diaphragm pumps, but the working mode of the diaphragm pump determines that the noise is large, and the suction force is low in the high-frequency breast pumping and lactation working mode, so that the breast pumping and lactation efficiency is low.
In addition, a small part of breast pumps on the market adopt piston pumps, but the transmission of a transmission mechanism of the breast pumps adopts straight-tooth gears, and the noise among the gears is high when the transmission mechanism runs; or a small number of gears are adopted, and because the factors such as manufacturing cost, attractive appearance and size are considered, the size of a transmission gear of the piston pump cannot be too large in a limited space in the shell of the breast pump, and the best suction force of the piston pump is difficult to achieve.

The embodiment scheme of the invention also provides a transmission mechanism of the breast pump, which can reduce the operation noise, occupy less space and increase the suction force of the piston pump. The embodiment of the invention also provides a breast pump with the transmission mechanism.

Furthermore, at least one pair of gears which are meshed with each other in the multi-section gear are driven by helical gears, so that the running noise can be better reduced compared with the case that all the gears adopt straight gears.
The transmission mechanism of the breast pump is used for transmission between a motor and a screw rod of a piston pump and comprises a driving gear set and a driven gear set, wherein the driving gear set is connected with the motor, the driven gear set is connected with the screw rod of the piston pump, and the driving gear set and the driven gear set are transmitted through a synchronous belt.
Further, the driving gear set and the driven gear set comprise six gears.
As a first structural embodiment, the driving gear set includes a first section, a second section, a third section, a fourth section and a fifth section of gear, and the driven gear set includes a sixth section of gear; the fifth section gear and the sixth section gear are both synchronous belt pulleys, the second section and the third section are coaxial gears, and the fourth section and the fifth section gear are coaxial gears.

The invention also provides a breast pump, which comprises a breast shield and a piston pump, wherein the piston pump is connected with the breast shield through an air duct, and comprises the transmission mechanism.
The improvement of the scheme of the invention brings the following advantages:
(1) the drive mechanism of breast pump of this application embodiment is different from the drive mechanism of breast pump among the prior art and all uses gear drive, and the drive mechanism of this application has driving gear group and driven gear group. The driving gear set is connected with a motor for providing power, and the driven gear set is connected with a screw rod of the piston pump. The driving gear set and the driven gear set are driven through the synchronous belt, the belt has certain flexibility and plays a role in noise reduction in contact operation with the gears, so that noise generated by direct meshing high-speed movement between the gears in the operation process of the transmission mechanism can be effectively reduced, overall working noise of the piston pump during working is reduced, and noise interference to a mother and a baby is reduced.
Compared with two breast pump tests which totally adopt gear transmission in the existing market, the transmission mechanism of the breast pump has the advantages that the noise is reduced by 2-2.5 decibels during operation; because the gear with large size is not used for long-distance transmission, the volume of the piston pump shell is reduced by 2-3%, the appearance structure is more attractive, and users can enjoy more stable and quiet comfortable experience when using the breast pump.
(2) Since the piston pump in a breast pump requires frequent reciprocation to pump air and exhaust air, this requires frequent forward and reverse rotation of the drive mechanism. In the prior art, a person skilled in the art generally considers that the use of a belt as a component of a transmission mechanism in a breast pump leads to a short service life of the belt due to such frequent forward rotation and reverse rotation, which in turn increases the failure rate of the breast pump and affects the user experience. However, the inventor of the present invention finds out through hundreds of tests that the breast pump has the characteristics of use (only in the lactation period of the user), the use frequency and the use time of the breast pump are not too high, the heat productivity is not large, the belt is made of wear-resistant rubber, the service life of the belt can meet the requirements of the industrial electric breast pump, and particularly, the breast pump transmission mechanism of the present invention can also greatly reduce the noise generated during the operation of the breast pump.
(3) According to the transmission method for the breast pump, the synchronous belt is connected with the transmission mechanism of the belt pulley, so that noise generated during direct transmission between gears can be reduced, transmission can be performed at positions far away from the gears, gears with large sizes do not need to be arranged, less space is occupied, and the internal space of the gear box is effectively utilized.
(4) As an improved structure, in order to improve the rotation speed ratio between the motor and the piston pump, the driving gear set and the driven gear set are combined to form six sections of gears, compared with the gears with fewer sections in the prior art, the six sections of gears can further improve the rotation speed ratio between the motor and the piston pump in the limited space of the shell of the breast pump, and provide more comfortable suction pressure for the breast.
(5) As an improved structure, at least one pair of gears which are meshed with each other in the six-section gear is driven by helical gears, so that the running noise can be better reduced than that of the whole six-section gear which adopts straight gears.
(6) The application provides a breast pump has foretell drive mechanism, and uses the piston pump, compares the diaphragm pump and has better silence effect, and manufacturing cost is lower after the casing volume reduces.
