Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of mother and baby products, and particularly to a breast pump and its diaphragm. Background Art

[0002] In modern household care devices, electric breast pumps have become an indispensable auxiliary tool for lactating mothers, greatly improving the convenience and efficiency of breastfeeding. However, with the continuous improvement of market requirements for the performance of breast pumps, especially the increasing demand for sealing and anti-backflow functions, the existing breast pump designs are facing new technical challenges.

[0003] Most traditional breast pump diaphragm designs focus on the effective transmission of suction and user comfort, but insufficient consideration is given to the cleaning problems caused by milk backflow into the main body of the machine and the possible damage to the machine. Common sealing solutions often rely on a single sealing structure, which is prone to leakage during long-term use or in the face of different pressure changes, resulting in milk seeping into the motor or electronic components of the breast pump, not only affecting the hygiene of the device, but also potentially causing machine failures and shortening the service life.

[0004] Existing improvement attempts in the market, such as increasing the thickness of the sealing ring or using higher-density materials, can alleviate the leakage problem to a certain extent, but often sacrifice the sucking comfort, increase the suction resistance, and do not fundamentally solve the problem of unstable sealing performance during the dynamic sucking process. In addition, the cost-benefit ratio of these improvement measures is not high, increasing the manufacturing cost and the maintenance burden of users.

[0005] Therefore, developing a breast pump diaphragm design that can effectively improve the sealing performance, prevent milk backflow, maintain a good user experience, and take into account the cost-benefit ratio has become an urgent technical problem to be solved. This is not only related to the actual utility of the product and user satisfaction, but also the key to promoting the technological progress of breast pumps and meeting market demands.

[0028] The diaphragm in a breast pump (usually made of elastic materials such as silicone) plays a crucial role in the operation of the device, especially in a diaphragm-type breast pump. The main functions of the diaphragm are as follows:

[0029] Forming a seal: The diaphragm fits closely with the pump body to form a sealed space. The change in the volume of this space creates a pressure difference, thereby generating suction.

[0030] Generating suction: When the diaphragm is driven by the driving device, it changes its shape, causing the volume of the air below the diaphragm to increase, thus reducing the pressure. This negative pressure is transmitted to the breast through the flared mouthpiece connected to the breast, simulating the effect of a baby sucking and prompting the milk to flow out.

[0031] Isolating components: The diaphragm separates the mechanical and electrical components of the breast pump from the milk, ensuring that the milk does not come into contact with any possible contaminants, and at the same time protecting the internal mechanical and electronic components from the influence of the milk.

[0032] Hygiene barrier: The diaphragm is a component that is easy to clean and replace. It can prevent bacteria and other microorganisms from accumulating inside the breast pump and maintain the hygiene of the milk extraction process.

[0033] Durability and elasticity: A high-quality diaphragm should have good elasticity and be able to maintain its shape and sealing performance after multiple uses. Once the diaphragm loses its elasticity or is damaged, the efficiency of the breast pump will decrease, and it may be necessary to replace the diaphragm to restore performance.

[0034] Please refer to Figures 1 to 4 , Figure 1 which is a three-dimensional structural schematic diagram of the first perspective of the diaphragm of the breast pump according to the embodiment of the present application; Figure 2 which is a three-dimensional structural schematic diagram of the second perspective of the diaphragm of the breast pump according to the embodiment of the present application;

[0035] Figure 3 which is a three-dimensional structural schematic diagram of the third perspective of the diaphragm of the breast pump according to the embodiment of the present application; Figure 4 which is a sectional structural schematic diagram of the diaphragm of the breast pump according to the embodiment of the present application.

[0036] In this embodiment, the diaphragm of the breast pump may include: a main body portion 10 and an opening portion 20. The main body portion 10 encloses a cavity 30 with a depth, and at least two sealing skirts 40, 50 are arranged at intervals from the outside to the inside on the end surface of the opening portion 20.

[0037] In this embodiment, the main body 10 is the core part of the diaphragm structure of the breast pump, and is designed to form a cavity 30 with a specific depth. This cavity 30 is connected to the negative pressure pump of the main body of the breast pump. The cavity formed by the main body acts on the cavity 30 to form a negative pressure in the cavity 30, promoting the contraction of the diaphragm, thereby driving milk extraction. The role of this diaphragm is to isolate gas and liquid between the milk extraction side and the negative pressure side, preventing milk from flowing back into the main body of the breast pump.

[0038] The opening part 20 is located at one end of the main body part 10. In order to ensure good sealing performance to prevent milk leakage and maintain suction, at least two sealing skirts 40, 50 are arranged at intervals from the outside to the inside on the end surface of the opening part 20. These sealing skirts 40, 50 are usually designed to be able to fit closely with other components of the breast pump to form a reliable sealing interface.

[0039] In one embodiment, at least two sealing skirts 40, 50 include a first sealing skirt 40 and a second sealing skirt 50. The first sealing skirt 40 is located on the inner side, and the second sealing skirt 50 is located on the outer side.

[0040] In some embodiments, the first sealing skirt 40 and the second sealing skirt 50 can be inclined, and the inclined directions of the first sealing skirt 40 and the second sealing skirt 50 are opposite. By the above method, the degree of fit between the first sealing skirt 40 and the second sealing skirt 50 and the sealing surface with which they cooperate after the breast pump is assembled is better, the fitting process is smoother, and the sealing effect is good.

[0041] The distance between the upper parts of the first sealing skirt 40 and the second sealing skirt 50 is greater than the distance between the lower parts of the first sealing skirt 40 and the second sealing skirt 50. The first sealing skirt 40 is inclined inward, and the second sealing skirt 50 is inclined outward.

[0042] In some embodiments, the number of sealing skirts can exceed two, and the embodiments of the present application do not limit this.

[0043] In some embodiments, the distance between the two sealing skirts 40, 50 gradually increases along the direction S of the opening of the opening part 20.

[0044] In one embodiment, at least one sealing rib 60, 70 is arranged between the two sealing skirts 40, 50. By further arranging the sealing ribs 60, 70 between the two sealing skirts 40, 50, the sealing performance can be further improved by the abutment between the sealing ribs 60, 70 and the sealing surface when the sealing skirts 40, 50 are in contact with the object sealing surface.

[0045] Optionally, the number of the sealing ribs 60, 70 is two, and the two sealing ribs 60, 70 protrude from the end surface of the opening part 20.

[0046] Optionally, the height by which the sealing ribs 60, 70 protrude in the direction S of the opening orientation of the opening portion 20 is less than the height of the sealing skirts 40, 50.

[0047] Optionally, the thickness of the sealing ribs 60, 70 is greater than the thickness of the sealing skirts 40, 50.

[0048] Optionally, the hardness of the sealing ribs 60, 70 is greater than the hardness of the sealing skirts 40, 50.

[0049] In some embodiments, the number of the sealing ribs 60, 70 can be configured to be more than two, and the embodiments of the present application do not limit this.

[0050] In some embodiments, the sealing rib 60 can be located at the connection between the sealing skirt 40 and the opening portion 20. The sealing rib 70 can be located at the junction between the sealing skirt 50 and the opening portion 20.

[0051] In one embodiment, a recessed structure 101 is provided on the main body portion 10 and recesses towards the cavity 30. The recessed structure 101 on the main body portion 10 is configured such that when the diaphragm is assembled on the breast pump, the recessed structure 101 faces the nipple channel of the breast pump and is in communication with the nipple channel. When receiving the milk flowing in from the nipple channel, the recessed structure can temporarily store the milk, thereby improving the milk suction flow rate, coping with the milk suction scenario with a large flow rate, and preventing the milk from being pushed back into the nipple channel when the diaphragm contracts.

[0052] In one embodiment, reinforcing ribs 102 are provided on the main body portion 10 at intervals in the depth direction. The function of the reinforcing ribs 102 is to enhance the resilience of the diaphragm. The contraction of the diaphragm depends on the negative pressure pump of the main unit, while the resilience of the diaphragm depends on its own elasticity, avoiding the jamming problem caused by untimely or non-resilience.

[0053] In one embodiment, a flanging 201 is provided on the opening portion 20, and a groove 80 for receiving the diaphragm bracket of the breast pump is formed between the flanging 201 and the main body portion 10. The diaphragm is placed in the diaphragm bracket during use, and the groove 80 is exactly used to receive the opening edge of the diaphragm bracket, which can facilitate the smooth placement of the diaphragm onto the diaphragm bracket, facilitate installation and disassembly, and facilitate the positioning of the opening portion 20.

[0054] In one embodiment, a handle 203 extending horizontally is formed on the opening portion 20. The number of the handles 203 can be two, which are respectively located on opposite sides. The design of the handles 203 can facilitate the removal of the diaphragm from the diaphragm bracket for cleaning, and can also facilitate holding during the cleaning process.

[0055] Another technical solution adopted by this application is: to provide a breast pump, and the breast pump includes the diaphragm described in any one of the above.

[0056] In the embodiment of the present application, by providing a diaphragm of the breast pump, the diaphragm includes a main body portion and an opening portion. The main body portion encloses a cavity with a depth, and at least two sealing skirts are arranged at intervals from the outside to the inside on the end surface of the opening portion. The unique multi-skirt design enhances the sealing effect and effectively solves the technical problem of milk backflow to the main unit. Specifically, this diaphragm design includes a main body portion that encloses a cavity with a depth, aiming to optimize the hydrodynamic characteristics during the sucking process; and at least two sealing skirts arranged at intervals from the outside to the inside on the end surface of the opening portion constitute multiple protection barriers, ensuring the sealing stability even under different pressure fluctuations. Thus, the overall sealing performance of the breast pump is greatly improved, preventing milk from leaking into the main unit, ensuring the cleanliness and long-term durability of the device, while maintaining a comfortable sucking experience.

It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.

[0058] The above are only the specific implementation manners of this application.
