Description

TECHNICAL FIELD

[0001] The utility model relates to a breast pump product, especially to a double-pump breast pump with fine adjustment frequency and milk flow. BACKGROUND

[0002] The breast pump is a tool for helping lactating mothers to suck and save milk, which mostly uses an electric pump to provide negative pressure and suck milk.

[0003] The current breast pump mostly has two forms, the first one is directly sucking the cover surface through the vacuum pump and forming a long-acting suction force to directly suck the milk, and the other one is sucking the milk by intermittently deforming the skin bowl in the breast pump through the vacuum pump and forming an intermittent negative pressure in the air chamber where the cover surface is located, and simulating the sucking action of the baby.

[0004] The direct sucking mode, although the suction force is stronger, but it will bring discomfort to the user and affect the use experience in the long term, and the other mode of intermittent sucking also has certain disadvantages, such as: ① the intermittent mode, the pump needs to deform the skin bowl to form negative pressure, which is easy to cause insufficient suction. ② Since the pump needs to deform the skin bowl, and the skin bowl is made of soft rubber, the internal stress is difficult to be uniformly stressed due to the nature of the material, so the skin bowl is easy to be damaged in the long term. ③ In the intermittent mode, the suction force is mainly affected by the deformation degree of the skin bowl, and the power of the pump is not the most direct variable, so it is difficult to fine tune the suction force.

[0005] In order to solve the above problems, the present scheme provides a double-pump breast pump with fine adjustment frequency and milk flow. CONTENT OF THE UTILITY MODEL

[0007] The breast milk suction device comprises a shell and a milk bottle connected below the shell, the shell has a breast milk suction cavity inside, one side of the shell has a cover surface, the cover surface has a through hole in the middle which communicates with the breast milk suction cavity, the breast milk suction cavity is separated into a first chamber and a second chamber by a deformation soft rubber, the first chamber communicates with the milk bottle, the deformation soft rubber maintains a first shape in normal state and can be in a second shape under negative pressure.

[0008] The host has a pump machine connected with the second chamber and providing negative pressure to the second chamber, when the pump machine works, the deformable soft glue can switch between the first and second forms, and the first chamber forms intermittent negative pressure, thereby sucking the emulsion through the cover surface and collecting the emulsion into the feeding bottle.

[0009] The deformable soft glue has a support part, both sides of the support part have deformable valves, and the deformable valves between different support parts are connected through a tensioning part, and the deformable valves and the tensioning part have an arc-shaped folding line.

[0010] In the first form, the deformable valves are folded along the folding line and close to each other, and the deformable valves and the support part form a deformable clamping groove.

[0011] In the second form, the tensioning part is stretched under the negative pressure, and the two opposite deformable valves connected on both sides of the tensioning part are forced and separated from each other, and the inner side of the deformable soft glue forms a bowl-shaped arc surface.

[0012] The shell includes a front cover surface part and a rear cover, the front cover surface part has a clamping pin, the rear cover has a buckle at a corresponding position of the clamping pin, and the front cover surface part and the rear cover are connected through the clamping pin and the buckle.

[0013] The rear cover has a negative pressure through hole, the pump machine output end of the host is connected to the negative pressure through hole through a pipeline, thereby the pump machine can pump out the air in the second chamber, and form a negative pressure in the second chamber to deform the deformable soft glue.

[0014] The front cover surface part has an emulsion communication hole, the bottom of the front cover surface part is connected with the feeding bottle through a thread, and the first chamber is communicated to the feeding bottle through the emulsion communication hole.

[0015] The number of the pump machines is at least two.

[0016] The host has a circuit board inside, and the circuit board is integrated with a control circuit for controlling the working frequency of the pump machine.

[0017] The embodiment of the present application has the following beneficial effects: ①The two pumps are arranged, so that stronger negative pressure can be formed in a short time, and the control circuit can be used for fine adjustment to realize accurate and stable output. ②The deformation soft rubber is deformed by the tensioning part and the deformation valve, so that the deformation posture of the deformation soft rubber is stable and controllable under negative pressure, thereby overcoming the problem that the deformation of the soft rubber material is unevenly stressed and is easy to be damaged under the traditional leather cup scheme. ③The quick-release clamping pin and the buckle are used, so that the front cover part and the rear cover can be quickly disassembled and assembled, thereby facilitating the disassembly, replacement and cleaning of the user.
