Description

Air bag chamber structure of a breast pump Technical Field

[0001] The present application relates to the field of breast pumps, and in particular to an air bag chamber structure of a breast pump. Background Art

[0002] A breast pump is a device that can imitate a baby's sucking to extract breast milk from the human body. There are many types of breast pumps, including electric, manual, and press types. The air bag compartment is an important component for forming negative pressure in the breast pump. Since the air bag compartment needs to be disassembled, cleaned and disinfected after each use of the breast pump, the structural design of the air bag compartment affects the user's subsequent usage experience. However, market research has found that the current air bag compartment has too many structural components, which makes it difficult for users to install, disassemble and clean, causes negative pressure leakage and unstable suction, or is too small to suck out milk.

[0003] Therefore, it is necessary to make further improvements. Technical Solutions

[0013] FIG2 is a schematic diagram of the structure of the breast shield and the air bag assembly after being disassembled. Modes for Carrying Out the Invention

[0014] In order to deepen the understanding of the present application, the present application will be further described in detail below in conjunction with examples and drawings. The examples are only used to explain the present application and do not constitute a limitation on the scope of protection of the present application.

[0015] Please refer to Figures 1-2. The present application provides an air bag warehouse structure of a breast pump, which includes a breast shield 1 and an air bag assembly 2. The rear side of the breast shield 1 has an airway cavity 3, the air bag assembly 2 is installed in the airway cavity 3, and the front and rear ends of the air bag assembly 2 are sealed with the airway cavity 3. An air bag body 21 is provided on the air bag assembly 2, and the inner side of the air bag body 21 forms a milk suction channel 4 connected to the breast shield 1, and the outer side of the air bag body 21 forms a suction area 5 between the air bag body 21 and the airway cavity 3, and a suction port 6 connected to the suction area is provided on the airway cavity 3. The air bag warehouse structure in this scheme is composed of the breast shield 1, the air bag body 21 and the structural frame 22 as a whole. The two ends of the air bag body 21 are sleeved on the two ends of the structural frame 22, and the air bag body is installed on the structural frame and installed in the airway cavity through the structural frame. It has the advantages of simple structure and easy disassembly and assembly, which is convenient for users to use and clean.

[0016] The two ends of the airbag body 21 are respectively provided with an outward-turned annular sleeve portion 211, and the front and rear ends of the structural frame 22 are provided with annular steps 221 that cooperate with the annular sleeve portion 211. The annular sleeve portion 211 is sealed and connected to the airway cavity 3. The use of this structure is more efficient in installing the airbag body, and the connection between the airbag body and the structural frame is tighter. When the structural frame is inserted into the airway cavity, the annular step is squeezed and deformed by the airway cavity, so that it fits tightly with the airway cavity and is sealed.

[0017] The end surface of the annular sleeve portion 211 in contact with the airway cavity 3 is provided with a first convex rib 7 that can be squeezed and deformed. The first convex rib 7 and the airbag body 21 are an integrally formed structure. The provision of the first convex rib can further enhance the sealing effect between the annular sleeve portion and the airway cavity and improve the air tightness.

[0018] The outer end surface of the annular sleeve portion 211 is provided with a second, extrudable, convex rib 8. A limiting step 9 is provided at the front end of the airway cavity 3, which abuts the front end of the airbag assembly 2. The second rib functions similarly to the first rib, enhancing airtightness. The second rib 8 is integrally formed with the airbag body 21. The airbag body 21 is made of a food-grade elastic soft rubber material, while the structural frame is made of a rigid, food-grade material. The entire airbag assembly is supported by both the elastic soft rubber and the rigid structural frame, effectively creating a negative pressure chamber and facilitating installation, disassembly, and disinfection.

[0019] The above description is only a preferred embodiment of the present application, and the protection scope of the present application is not limited to the above embodiment. Any equivalent modifications or changes made by ordinary technicians in this field based on the content disclosed in this application should be included in the protection scope recorded in the claims.
