Description

Technical Field

[0001] This utility model relates to the field of breast pump technology, and more specifically, to a leather cup assembly and an electric breast pump. Background Technology

[0002] A breast pump is a common maternal and infant care tool, primarily used to help breastfeeding mothers express breast milk from their breasts for storage or feeding their babies. Breast pumps are used in a wide range of situations in daily life, such as when mothers need to express milk at work, in public places, or while traveling, where they become particularly important.

[0003] However, most breast pumps on the market currently have some obvious design flaws.

[0004] 1. Noise problem

[0005] Most existing breast pumps use an air pump as their power source. The air pump generates negative pressure to drive the breast cups in a reciprocating motion, thus achieving the milk expression function. The air pump produces considerable noise during operation. For breastfeeding mothers, using a breast pump often requires a quiet and comfortable environment, especially in public places or when the baby is sleeping. This noise may disturb those around them and even cause embarrassment and inconvenience to the mother.

[0006] 2. Poor portability

[0007] Because of the air pump, breast pumps typically require a long air tube and a separate pump control box. These components not only increase the size and weight of the breast pump but also make the entire device bulky. When using it, mothers need to carry the air tube and control box and ensure the air tube connection is secure to prevent leaks. This complex structure significantly reduces the portability of the breast pump, making it extremely inconvenient, especially when out and about.

[0008] Therefore, this utility model aims to solve the problems of existing breast pumps, such as high noise and poor portability. Utility Model Content

[0009] The utility model description section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This utility model description section is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0010] To at least partially solve the above problems, this utility model provides a leather cup assembly, including: a flexible movable member, and a connector connected to a driving device;

[0011] The outer edge of the movable component is connected to the bracket, and the movable component has a first surface that is connected to the connector and a second surface facing the direction of the bottle;

[0012] The connector has a first connecting surface that connects to a first surface, and a second connecting surface that connects to a drive device;

[0013] The first surface and the first connecting surface are in contact with each other, and the driving device and the second connecting surface are in contact with each other.

[0014] Preferably, the movable component has a bowl-shaped structure, and the opening of the movable component faces the driving device. The inner surface of the movable component facing the driving device is the first surface, and the outer surface facing the suction cup assembly is the second surface.

[0015] Preferably, the sidewall of the movable component has at least one annular protrusion that protrudes in the direction of the opening.

[0016] Preferably, at least one annular protrusion protruding in the opening direction is located within the range of the first surface.

[0017] The leather cup assembly according to any one of the claims, characterized in that the connector is located within the movable member, and the shape of the connector is adapted to the shape of the movable member.

[0018] Preferably, the second connecting surface of the connector is provided with a connecting post for contact connection with the driving device.

[0019] Preferably, the end of the connecting column facing the driving device is provided with a mounting groove, and the driving device and the mounting groove are in contact connection.

[0020] Preferably, the contact connection between the first surface and the first connecting surface includes abutment, material connection, or structural connection.

[0021] Preferably, the contact connection between the drive device and the second connection surface includes abutment, material connection, or structural connection.

[0022] An electric breast pump includes: a drive device mounted on a bracket, a control board and a power supply, a suction cup assembly connected to the bracket, and a baby bottle detachably connected to the suction cup assembly. It also includes a leather cup assembly connected to the bracket via a movable component. The suction cup assembly is connected to the bracket, and the movable component of the leather cup assembly seals the suction cup assembly. The drive device is connected to a connector of the leather cup assembly, and the drive device drives the movable component to reciprocate within the suction cup assembly via the connector.

[0023] Compared with the prior art, the present invention has at least the following beneficial effects:

[0024] To address the various inconveniences of existing breast pumps, we eliminated the structural design that used an air pump as a power source to drive the breast cup assembly. Instead, we replaced the air pump with a drive device to drive the moving parts in reciprocating motion. This not only solved many problems of existing breast pumps but also brought about a significant improvement in user experience.

[0025] 1. Quiet and silent

[0026] Modern breast pumps use air pumps, which produce a buzzing noise when operating. By using a drive unit 101 instead of an air pump, the breast pump operates almost silently, as quiet as a vibrating cell phone. This means mothers can use the breast pump anywhere, such as in the baby's room, without disturbing the baby.

[0027] 2. Lightweight and easy to carry

[0028] This invention can directly integrate the drive device into the breast pump, eliminating the need for air pipes, pump control boxes, and various electromagnetic valves related to the air pump, making the entire breast pump compact and lightweight.

[0029] The leather cup assembly and electric breast pump described in this utility model, other advantages, objectives and features of this utility model will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this utility model.

[0041] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0042] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0043] like Figures 1-9 As shown, this utility model provides a leather cup assembly, including: a flexible movable member 1, and a connecting member 2 connected to a driving device 101; the shapes of the movable member 1 and the connecting member 2 are not specifically limited, but generally the top views of the movable member 1 and the connecting member 2 are symmetrical figures, for example... Figure 2 and Figure 3 In the illustrated embodiment, the top view of the movable part 1 and the connecting part 2 is circular. Furthermore, the surface area of ​​the connecting part 2 is typically not larger than the surface area of ​​the movable part 1, such as... Figure 1-9 In the embodiment shown, the diameter of the connector 2 is not greater than the diameter of the movable part 1, so that after the connector 2 is connected to the movable part 1, the movable part 1 still has sufficient room for movement.

[0044] The outer edge of the movable component 1 is connected to the bracket 100, such as Figure 6 and Figure 7 As shown, as one of the many embodiments, the outer edge of the movable member 1 can be connected to the bracket 100 by a snap-fit ​​method. That is, a number of protrusions are provided on the inner wall of the bracket 100, and the outer edge of the movable member 1 forms an outwardly extending retaining ring. The retaining ring can be snapped on the top of the protrusion, thereby forming a connection between the outer edge of the movable member 1 and the bracket 100.

[0045] A sealed connection is formed between the movable part 1 and the suction cup assembly 200. The suction cup assembly 200 can be directly connected to the bracket 100. At this time, the movable part 1 is located inside the suction cup assembly 200. Therefore, the movable part 1 needs to form a sealed connection with the bracket 100. Alternatively, when the suction cup assembly 200 is connected to the bracket 100, it can press against the outer edge of the movable part 1, thereby forming a sealed connection between the second surface 4 of the movable part 1 and the suction cup assembly 200. The sealed connection can be a fixed connection such as adhesive bonding, or a detachable connection, as long as the movable part 1 can achieve a seal on the suction cup assembly 200.

[0046] Since there is no specific limitation on the shape of the movable part 1, the movable part 1 should have at least a first surface 3 connected to the connector 2 and a second surface 4 facing the direction of the bottle 300; the two surfaces are oriented in opposite directions, the second surface 4 faces the direction of the bottle 300 and is used to seal the suction cup assembly 200, and the first surface 3 is used to connect to the connector 2.

[0047] Since there is no specific limitation on the shape of the connector 2, the connector 2 should have at least a first connecting surface 5 connected to the first surface 3 and a second connecting surface 6 connected to the driving device 101; the two connecting surfaces are oriented in opposite directions, the first connecting surface 5 is used to connect to the first surface 3, and under the drive of the driving device 101, the connector 2 applies a force to the first surface 3 through the first connecting surface 5, and the second connecting surface 6 is connected to the driving device 101.

[0048] The first surface 3 and the first connecting surface 5 are in contact with each other. The contact connection between the first surface 3 and the first connecting surface 5 includes abutment, material connection or structural connection. For example, the first connecting surface 5 can abut against the first surface 3; the first surface 3 and the first connecting surface 5 can also be bonded by adhesive or other substances (i.e., material connection); a protruding limiting structure can be provided on the first surface 3 and a concave limiting structure can be provided on the first connecting surface 5, and a structural connection can be formed by the mutual cooperation of the limiting structures (i.e., structural connection).

[0049] The drive device 101 and the second connecting surface 6 are in contact connection. This contact connection includes abutment, material connection, or structural connection. Taking a motor capable of reciprocating linear motion as an example, the motor's output shaft can abut against the second connecting surface 6; it can also be bonded using adhesive or similar materials (i.e., material connection); a connecting post 8 can be provided on the second connecting surface 6 to connect to the drive device 101. The connecting post 8 can be a rigid structure, with the motor's output shaft fitted onto it using a sleeve or similar structure (i.e., structural connection); a mounting groove 9 can be provided at the end of the connecting post 8 facing the drive device 101, with the motor's output shaft inserted into the mounting groove 9; the motor's output shaft can also be bonded to the mounting groove 9; or the mounting groove 9 can be a threaded groove, with an external thread on the motor's output shaft adapted to the threaded groove, allowing the motor's output shaft to be threadedly connected to the mounting groove 9.

[0050] The working principle and beneficial effects of the above technical solution: In order to solve the various inconveniences of existing breast pumps, we have eliminated the structural design of using an air pump as a power source to drive the breast cup assembly. Instead, we use a drive device 101 to replace the air pump and drive the moving part 1 to reciprocate. This not only solves many problems of existing breast pumps, but also brings a significant improvement in user experience.

[0051] 1. Quiet and silent

[0052] Modern breast pumps use air pumps, which produce a buzzing noise when operating. By using a drive unit 101 instead of an air pump, the breast pump operates almost silently, as quiet as a vibrating cell phone. This means mothers can use the breast pump anywhere, such as in the baby's room, without disturbing the baby.

[0053] 2. Lightweight and easy to carry

[0054] This invention can directly integrate the drive device 101 into the breast pump, eliminating the need for air pipes, pump control boxes, and various electromagnetic valves related to the air pump, making the entire breast pump compact and lightweight.

[0055] Furthermore, the movable component 1 has a bowl-shaped structure. It should be noted that the term "bowl" here essentially refers to a deformable diaphragm that initially or after activation takes on a bowl shape, regardless of whether its shape is flat or bowl-shaped. The opening of the movable component 1 faces the driving device 101. Figure 8 As shown, the movable member 1 extends towards the suction cup assembly 200, allowing it to penetrate into the interior of the suction cup assembly 200. This seals the suction cup assembly 200 while ensuring a sufficiently large stroke. The movable member 1 faces the inner surface of the driving device 101 (i.e., the concave surface, such as...). Figure 5 As shown, the first surface 3 faces the outer surface of the suction cup assembly 200 (i.e., the convex surface, such as...). Figure 5 (As shown) is the second surface 4.

[0056] Furthermore, at least one annular protrusion 7 protruding towards the opening direction is provided on the side wall of the movable component 1. The annular protrusion 7 is typically formed by bending the side wall of the movable component 1 towards the opening direction, creating an n-shaped cross-section. Figure 5 As shown, under the drive of the drive device 101, the annular protrusion 7 can be stretched, thereby providing a sufficiently large stroke for the movable part 1, while also optimizing and reducing the area occupied by the movable part 1.

[0057] Furthermore, at least one annular protrusion 7 protruding in the opening direction is located within the area of ​​the first surface 3. The connector 2 is located within the movable member 1, and the shape of the connector 2 is adapted to the shape of the movable member 1. By providing the annular protrusion 7 within the area of ​​the first surface 3, it is ensured that the shape of the first connecting surface 5 can be adapted to the annular protrusion 7, and when the first surface 3 and the first connecting surface 5 are in contact connection, it is ensured that the two have a sufficiently large contact area, thereby ensuring the firmness of the contact connection.

[0058] This invention also provides an electric breast pump, comprising: a drive device 101 mounted on a bracket 100, a control board 102 and a power supply 103, a suction cup assembly 200 connected to the bracket 100, and a baby bottle 300 detachably connected to the suction cup assembly 200. To make the breast pump portable, a top cover 104 is typically provided on the bracket 100 to encapsulate the drive device 101, control board 102 and power supply 103 on the bracket 100, thereby achieving an integrated design of the breast pump. Because there is no need for an air tube and pump control box, the bracket 100 can eliminate the structural design of air vents and solenoid valves, thus simplifying the manufacturing process of the bracket 100. The bracket 100, drive device 101, and control board... Components 102, 103, 104, 200, and 300 are all commercially available products or existing technologies. The positional and electrical connection relationships between these components are also existing technologies. A switch electrically connected to the control board 102 can be installed on the 104. The system also includes a leather cup assembly connected to the support 100 via a movable part 1. The suction cup assembly 200 is connected to the support 100, and the movable part 1 of the leather cup assembly seals the suction cup assembly 200. The drive device 101 is connected to the connecting part 2 of the leather cup assembly, and the drive device 101 drives the movable part 1 to reciprocate within the suction cup assembly 200 via the connecting part 2. By using the drive device 101 instead of an air pump, the breast pump operates almost silently, as quiet as a vibrating mobile phone. This invention can also directly integrate the drive device 101 into the breast pump, eliminating the need for air pipes, a pump control box, and various electromagnetic valves related to the air pump, making the entire breast pump compact and lightweight. Furthermore, it simplifies the structural design and manufacturing process of the bracket 100, significantly reducing production costs. If the bracket 100 of the prior art (i.e., the bracket 100 with air holes and a solenoid valve mounting structure) is adopted, the versatility of this utility model can be improved, allowing users to switch between the two usage modes of the air pump and the drive device 101.
