Description

Technical Field

[0001] The utility model relates to the technical field of vacuum devices, in particular to an integrated valve type vacuum pump, a breast pump host and a breast pump. Background Art

[0002] Existing breast pumps primarily use a vacuum pump to extract air, creating a negative-pressure cavity to draw milk into the milking channel. A bleed valve is then opened to allow outside air to enter the negative-pressure cavity, restoring the pressure to atmospheric pressure and simultaneously discharging the milk from the milking channel into the atmospheric-pressure milk storage chamber.

[0003] During the aforementioned milk extraction and letdown process, the vacuum pump and air release valve are core components of the breast pump. However, their large overall size restricts the internal structural layout of the breast pump, resulting in a larger overall size. Furthermore, both the vacuum pump and air release valve require electrical power, and the size of the battery is limited by the device's size. This restricts the size of the breast pump, resulting in a poor user experience. Utility Model Content

[0004] The main purpose of the utility model is to provide an integrated valve vacuum pump, a breast pump host and a breast pump, aiming to solve the problem that the vacuum pump and the air release valve limit the volume of the breast pump.

[0005] To achieve the above-mentioned objectives, the present invention proposes an integrated valve vacuum pump, which includes an exhaust assembly, a drive motor, a shell and a rotating shaft. An air cavity is formed in the shell, and the shell is provided with an air vent and a connecting channel connected to the breast pump. The air vent connects the air cavity with the outside world. The drive motor is used to drive the rotating shaft to rotate and drive the exhaust assembly through the rotating shaft to form a negative pressure space in the air cavity. The integrated valve vacuum pump also includes a linkage and a sealing member; the sealing member is configured to open or seal the air vent; when the drive motor drives the rotating shaft to rotate, the linkage rotates so that the seal seals the air vent, and when the drive motor stops working, the seal opens the air vent.

[0006] In one embodiment, the sealing portion of the sealing member is located on a side of the linkage member that is away from the rotating shaft along the radial direction of the rotating shaft.

[0007] In one embodiment, the air vent is provided on a side wall of the housing.

[0008] In one embodiment, the linkage member is rotatably connected to the sealing member.

[0009] In one embodiment, the linkage member includes an inclined surface or a curved surface. When the drive motor rotates, the inclined surface or the curved surface of the linkage member moves relative to the rotating shaft to squeeze the sealing member so that the sealing member seals the air leakage port.

[0010] In one embodiment, an elastic member is further included, and the elastic member is used to reset the sealing member and the linkage member when the driving motor stops working.

[0011] In one embodiment, the elastic member is connected between the linkage member and the sealing member, or the elastic member is connected between the housing and the sealing member.

[0012] In one embodiment, the linkage member and the rotating shaft are elastically connected.

[0013] The utility model also provides a breast pump host, which includes an integrated valve vacuum pump and a battery for providing electrical energy to the pump.

[0014] The utility model further provides a breast pump, comprising: a breast pump main body, a suction cup communicated with the air cavity, and a milk storage container, wherein the milk storage container is used for storing milk sucked out by the suction cup.

[0015] The present invention integrates a vacuum pump with a bleed valve. This integrated valve vacuum pump includes a vacuum assembly, a drive motor, a housing, and a rotating shaft. An air chamber is defined within the housing, along with a bleed port and a connecting channel for the breast pump. The bleed port controls air flow between the air chamber and the outside environment. The vacuum assembly and drive motor are mounted within the housing, connected to the vacuum assembly via a rotating shaft. When the drive motor is activated, it rotates the rotating shaft, driving the vacuum assembly to generate negative pressure within the air chamber. This negative pressure draws milk into the breast pump through the connecting channel. To control the negative pressure within the air chamber, a linkage and a seal are incorporated into the pump. The seal seals the bleed port when the air chamber needs to maintain negative pressure, preventing outside air from entering. When the drive motor is operating, the linkage rotates, driving the seal to seal the bleed port. Once the drive motor stops, the linkage also stops, causing the seal to open the bleed port, allowing outside air to enter the air chamber, thereby breaking the negative pressure and draining milk from the suction channel into the milk storage container. In this way, by precisely controlling the start and stop of the drive motor, effective milk extraction and discharge can be achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The utility model provides an integrated valve type vacuum pump 100 .

[0029] See also Figure 1 In one embodiment of the present utility model, the integrated valve vacuum pump 100 includes an exhaust assembly 1, a drive motor 2, a housing 3 and a rotating shaft 4. An air cavity 3a is formed in the housing 3. The housing 3 is provided with an air vent 3b and a connecting channel connected to the breast pump. The air vent 3b connects the air cavity 3a with the outside world. The drive motor 2 is used to drive the rotating shaft 4 to rotate and drive the exhaust assembly 1 through the rotating shaft 4 to form a negative pressure space in the air cavity 3a. The integrated valve vacuum pump 100 also includes a linkage 5 and a sealing member 6; the sealing member 6 is configured to open or seal the air vent 3b; when the drive motor 2 drives the rotating shaft 4 to rotate, the linkage 5 rotates to cause the sealing member 6 to seal the air vent 3b, and when the drive motor 2 stops working, the sealing member 6 opens the air vent 3b.

[0030] In this embodiment, the vacuum assembly 1 is a key component of the integrated valve vacuum pump 100. Its primary function is to generate and maintain a negative pressure within the air cavity 3a. The vacuum assembly 1 can be designed as a diaphragm made of a flexible material, mounted within the air cavity 3a and mechanically connected to the rotating shaft 4. One side of the diaphragm communicates with the air cavity 3a, while the other side forms a sealed chamber. The rotating shaft 4 is connected to the input end of the diaphragm via a mechanical connection (such as a gear, belt, or direct connection). When the drive motor 2 is activated and drives the rotating shaft 4 to rotate, the diaphragm undergoes reciprocating motion. This reciprocating motion of the diaphragm causes the volume within the air cavity 3a to periodically change. When the diaphragm moves and reduces the volume of the air cavity 3a, the air within the air cavity 3a is expelled, creating a negative pressure. When the diaphragm moves and increases the volume of the air cavity 3a, outside air enters the air cavity 3a through the vent 3b, releasing the negative pressure. To control the generation and release of negative pressure, the vacuum assembly 1 can be equipped with a linkage 5 that interacts with a sealing element 6. During the negative pressure generation stage, the linkage 5 causes the seal 6 to close the air vent 3b to prevent air from entering; during the negative pressure release stage, the linkage 5 causes the seal 6 to open the air vent 3b to allow air to flow in. The material of the vacuum component 1 needs to have sufficient flexibility and durability to withstand long-term reciprocating motion without fatigue damage. Commonly used materials include silicone, rubber, polytetrafluoroethylene (PTFE), etc. The entire vacuum component 1 is integrated in the housing 3, and together with the drive motor 2, the rotating shaft 4, the linkage 5 and the seal 6, it forms a compact and efficient vacuum pump system.

[0031] The drive motor 2 is a core component of the integrated valve vacuum pump 100. It provides power to activate the vacuum assembly 1 and the opening and closing of the vent 3b, thereby generating intermittent negative pressure. The drive motor 2 can be a DC motor, a brushless motor, or a stepper motor. These motor types offer precise control and high efficiency. To accommodate the compact design of the integrated valve vacuum pump 100, the drive motor 2 needs to be as small as possible while still ensuring sufficient torque output to drive the vacuum assembly 1. The speed of the drive motor 2 can be adjusted via the motor driver and control system. In breast pump applications, different suction rates may be required to suit different user needs, so the speed of the drive motor 2 should be adjustable. The drive motor 2 needs to provide sufficient torque to ensure that the vacuum assembly 1 can effectively generate negative pressure within the air chamber 3a. The torque directly affects the suction force. The torque motor is typically directly connected to the vacuum assembly 1 via a rotating shaft 4. In breast pump applications, the noise level of the drive motor 2 should be as low as possible to provide a comfortable user experience. Brushless motors are generally quieter than other types of motors.

[0032] Furthermore, the housing 3 is the basic part of the integrated valve vacuum pump 100, which provides accommodation space and structural support for other components of the integrated valve vacuum pump 100, such as the vacuum assembly 1, the drive motor 2, the rotating shaft 4, etc. The housing 3 is usually made of a durable and lightweight material, such as aluminum alloy or plastic, to reduce the overall weight while ensuring strength. The housing 3 is formed with an air cavity 3a and an air vent 3b and a connecting channel connected to the air cavity 3a. The air cavity 3a is the key part for forming negative pressure, and the air vent 3b is used to control the gas exchange between the air cavity 3a and the outside world. The design of the housing 3 must ensure good sealing to maintain the negative pressure state in the air cavity 3a.

[0033] It should be noted that the rotating shaft 4 is responsible for transmitting the rotational motion of the motor to the vacuum assembly 1. The rotating shaft 4 is usually made of high-strength steel or alloy materials to ensure its durability and reliability under high load conditions. The connection between the rotating shaft 4 and the motor and the vacuum assembly 1 can be direct or achieved through a coupling, gears or other transmission devices to meet different design requirements. In order to reduce friction and ensure the smooth operation of the rotating shaft 4, precision bearings will be installed on the rotating shaft 4. These bearings can withstand axial and radial loads. The part of the rotating shaft 4 that passes through the housing 3 needs to have good sealing performance to prevent air leakage and maintain the negative pressure state in the air cavity 3a.

[0034] The linkage 5 can transmit the movement of the rotating shaft 4 to the seal 6, achieving coordinated movement between the two components. In the integrated valve vacuum pump 100, the function of the linkage 5 is to synchronously operate the seal 6 to control the opening and closing of the vent 3b when the drive motor 2 drives the rotating shaft 4 to rotate. The linkage 5 can be designed as a cam, gear or connecting rod structure, one end of which is connected to the rotating shaft 4 and the other end is connected to the seal 6. When the rotating shaft 4 rotates, the linkage 5 rotates or swings accordingly. The linkage 5 is usually made of metal materials, such as stainless steel or aluminum alloy, to ensure its strength and durability. The rotational motion of the rotating shaft 4 is converted into linear motion by the linkage 5 to drive the seal 6. One end of the linkage 5 is connected to the seal 6, and when the rotating shaft 4 rotates, the linkage 5 pushes the seal 6 to move, thereby achieving the opening and closing of the vent 3b. The design of the linkage 5 needs to ensure precise control of the position of the seal 6 to maintain the sealing and negative pressure state of the air cavity 3a.

[0035] In the present embodiment, the seal 6 is a key component for maintaining negative pressure in the air cavity 3a. In the integrated valve vacuum pump 100, the function of the seal 6 is to open the air vent 3b when the drive motor 2 stops working, and to seal the air vent 3b when the drive motor 2 is working, so as to maintain the negative pressure state in the air cavity 3a. According to the working environment (such as temperature, pressure, medium, etc.) in the air cavity 3a, a suitable sealing material is selected. Commonly used sealing materials include nitrile rubber, fluororubber, silicone rubber, polytetrafluoroethylene, etc. The seal 6 can be designed to be a shape that can form a good seal with the periphery of the air vent 3b, such as an O-ring, a cylindrical or other shaped seal 6, to ensure that no leakage occurs under negative pressure. The seal 6 is correctly installed in the position of the air vent 3b to ensure that it can correctly open and close the air vent 3b under the drive of the rotating shaft 4.

[0036] The present invention integrates a vacuum pump 1 with a bleed valve. This integrated valve vacuum pump 100 comprises a vacuum assembly 1, a drive motor 2, a housing 3, and a rotating shaft 4. An air chamber 3a is defined within the housing 3, along with a bleed port 3b and a connecting channel for the breast pump. The bleed port 3b controls air flow between the air chamber 3a and the outside environment. The vacuum assembly 1 and drive motor 2 are mounted within the housing 3, connected to the vacuum assembly 1 via the rotating shaft 4. When the drive motor 2 is activated, it rotates the rotating shaft 4, driving the vacuum assembly 1 to generate negative pressure within the air chamber 3a. This negative pressure then draws milk into the breast pump through the connecting channel. To control the negative pressure within the air chamber 3a, a linkage 5 and a seal 6 are incorporated into the pump. The seal 6 seals the bleed port 3b when the air chamber 3a needs to maintain negative pressure, preventing outside air from entering. When the drive motor 2 is operating, the linkage 5 rotates, driving the seal 6 to seal the bleed port 3b. Once the drive motor 2 stops, the linkage 5 also stops, causing the seal 6 to open the vent 3b, allowing outside air to enter the air chamber 3a, thereby breaking the negative pressure and draining the milk in the milking channel into the milk storage container. In this way, by precisely controlling the starting and stopping of the drive motor 2, efficient milk extraction and discharge can be achieved.

[0037] In one embodiment of the present invention, please refer to Figure 4 The sealing portion of the sealing member 6 is located on a side of the linkage member 5 that is away from the rotating shaft 4 in the radial direction of the rotating shaft 4 .

[0038] In this embodiment, the sealing portion of seal 6 is located radially away from one end of shaft 4, enabling effective control of the opening and closing of vent 3b when linkage 5 is actuated. Specifically, seal 6 is first installed in a suitable position on housing 3, ensuring it is radially away from shaft 4 and with one end away from shaft 4. Seal 6 can be designed as a radially sealed cylinder, with its sealing portion located at one end of vent 3b, forming a sealing contact with the edge of vent 3b. Seal 6 can be made of rubber, polytetrafluoroethylene (PTFE), or other synthetic materials to achieve a good seal. Seal 6 is installed in a designated position on housing 3, ensuring its sealing portion is aligned with the edge of vent 3b and capable of opening and closing vent 3b in response to the movement of linkage 5. The motion trajectory and force of linkage 5 are adjusted to ensure that when the drive motor 2 is operating, linkage 5 pushes seal 6 to seal vent 3b; when the drive motor 2 is stopped, linkage 5 pulls seal 6 to open vent 3b. Through proper installation and connection, it can be ensured that the seal 6 is correctly installed and works in the radial direction of the rotating shaft 4, thereby effectively controlling the gas exchange between the air cavity 3a and the external environment.

[0039] In one embodiment of the present invention, please refer to Figure 5 The air vent 3b is provided on the side wall of the shell 3.

[0040] In one embodiment, an air vent 3b is provided on the side wall of the shell 3 for adjusting the air pressure in the air cavity 3a. In order to achieve position control between the seal 6 and the air vent, an extension portion can be provided on the peripheral side of the shell 3 near the air vent 3b. The extension portion protrudes from the main structure of the shell 3 and has an extension groove inside. A portion of the structure of the seal 6 is placed in the extension groove, and a certain gap is maintained between it and the inner wall of the extension groove, thereby allowing the seal 6 to move flexibly in the extension groove. Silencing cotton can also be provided at the outlet position of the air vent 3b. The silencer cotton can be used to reduce the noise generated when the air vent 3b is deflated, thereby improving the user experience.

[0041] In one embodiment of the present invention, please refer to Figure 3 and Figure 4 , the linkage member 5 is rotationally connected to the sealing member 6.

[0042] In this embodiment, the rotational connection between the linkage 5 and the seal 6 is key to ensuring precise control of the vent 3b in the integrated valve vacuum pump 100. Specifically, the linkage 5 is typically designed as a rotatable lever, cam, or rocker arm, with one end connected to the rotating shaft 4 and the other end connected to the seal 6. This design allows the linkage 5 to rotate under the drive of the rotating shaft 4, thereby driving the seal 6 to open or close the vent 3b. The linkage 5 and seal 6 can be connected directly or via bearings, hinges, pins, or other joints. These connection methods must be able to withstand rotational motion and ensure that the seal 6 accurately responds to the movement of the linkage 5. The material selection for the linkage 5 and seal 6 must take into account wear resistance, corrosion resistance, and strength. Common materials include stainless steel, engineering plastics, rubber, or special alloys. The seal 6 must be secured in place within the housing 3 so that the linkage 5 can properly seal the vent 3b. The seal 6 can be installed using methods such as press fit, slotting, or bolting. The rotational motion of the rotating shaft 4 is transmitted to the sealing member 6 through the linkage member 5, so that the sealing member 6 can move precisely at the air release port 3b to achieve the functions of sealing and pressure relief.

[0043] In one embodiment of the present invention, please refer to Figure 2 and Figure 4 The linkage member 5 includes an inclined surface or a curved surface. When the drive motor 2 rotates, the inclined surface or the curved surface of the linkage member 5 moves relative to the rotating shaft 4 to squeeze the sealing member 6 so that the sealing member 6 seals the air leakage port 3b.

[0044] In one embodiment, the rotational connection between the linkage 5 and the sealing member 6 of the integrated valve vacuum pump 100 can be achieved by providing an inclined surface or a curved surface on the linkage 5. When the drive motor 2 rotates, the inclined surface or the curved surface on the linkage 5 will move relative to the rotating shaft 4, squeezing the sealing member 6 so that it seals the air leakage port 3b. Specifically, the linkage 5 will be designed to include inclined surfaces or curved surfaces, which will cause the sealing member 6 to move linearly when the linkage 5 rotates, thereby squeezing the sealing member 6. When the drive motor 2 is working and the rotating shaft 4 rotates, the linkage 5 rotates accordingly, and the inclined surface or the curved surface thereon generates radial pressure on the sealing member 6, thereby sealing the air leakage port 3b. Through such a design, precise control of the air leakage port 3b of the vacuum pump can be achieved, thereby improving the working efficiency and performance of the pump.

[0045] In one embodiment of the present invention, please refer to Figure 5 , and also includes an elastic member 7, which is used to reset the sealing member 6 and the linkage member 5 when the drive motor 2 stops working; the elastic member 7 is connected between the linkage member 5 and the sealing member 6, or the elastic member 7 is connected between the housing 3 and the sealing member 6.

[0046] In one embodiment, the integrated valve vacuum pump 100 further includes an elastic member 7. This elastic member 7 provides the necessary restoring force when the drive motor 2 stops, returning the seal 6 and linkage 5 to their initial positions and ensuring proper opening of the vent 3b. Specifically, the elastic member 7 can be designed as a spring or other structure, with one end secured to the housing 3 and the other end connected to the linkage 5. When the drive motor 2 is operating, the linkage 5 overcomes the spring force and pushes the seal 6 to seal the vent 3b. When the motor stops, the spring force resets the linkage 5 and seal 6. The elastic member 7 can be a compression spring, an extension spring, or a torsion spring, depending on the required force and motion. The elastic member 7 is typically mounted inside the housing 3, near the linkage 5, to facilitate the transmission of the restoring force. In another embodiment, the force of the elastic member 7 acts on the seal 6, ensuring that the seal 6 quickly returns to its original position and opens the vent 3b when the motor stops. The material of the elastic member 7 needs to have good elasticity and fatigue resistance. Commonly used materials include spring steel, stainless steel, or specialty plastics.

[0047] In one embodiment of the present invention, please refer to Figure 2 and Figure 5 , the linkage member 5 and the rotating shaft 4 are elastically connected.

[0048] In this embodiment, the elastic connection between the linkage 5 and the rotating shaft 4 can be achieved using an elastic coupling. This coupling typically contains an elastomeric compound with pre-stressed rubber, providing additional strength and extending service life. This elastic connection allows for a certain range of axial, radial, and angular misalignment, while increasing friction between the linkage 5 and the rotating shaft 4, facilitating precise transmission. An integrally molded metal elastomer coupling can be selected. This coupling achieves zero backlash and synchronous operation, while also providing elasticity to compensate for radial, angular, and axial misalignment. The hub of the elastic coupling is typically made of high-strength aluminum alloy, which is both lightweight and corrosion-resistant. The rubber portion is a split insert that can be installed by inserting after shaft alignment. Flexible couplings offer two main fixing methods: screwing and clamping, adapting to different installation requirements and spatial conditions. Flexible couplings offer excellent performance and a competitive price, making them the preferred choice in many stepper and servo system applications. Because the rubber portion of the flexible coupling is split, it can be installed by inserting after shaft alignment, facilitating maintenance and replacement. By using the elastic coupling, an elastic connection between the linkage member 5 and the rotating shaft 4 can be achieved, thereby ensuring efficient and reliable operation of the vacuum pump.

[0049] The present invention also provides a breast pump system comprising an integrated valve vacuum pump 100 and a battery for providing power to a vacuum assembly 1. The specific structure of the integrated valve vacuum pump 100 is similar to the above-described embodiments. Since the present breast pump system utilizes all the technical solutions of all of the above-described embodiments, it possesses at least all the beneficial effects of the technical solutions of the above-described embodiments, and therefore will not be further elaborated upon here.

[0050] The present invention also provides a breast pump comprising a suction cup communicating with an air cavity 3a and a milk storage container. The specific structure of the breast pump main unit is similar to that of the aforementioned embodiments. Since the present breast pump utilizes all the technical solutions of all of the aforementioned embodiments, it possesses at least all the beneficial effects of the technical solutions of the aforementioned embodiments, and therefore will not be further elaborated here. The milk storage container is used to store milk extracted by the suction cup.

[0051] In this embodiment, a breast pump is provided. The core component of the breast pump is the main unit, which includes an integrated valve vacuum pump 100 and a battery that provides power to the vacuum assembly 1. The integrated valve vacuum pump 100 precisely controls the negative pressure within the air chamber 3a to simulate a baby's sucking action, effectively extracting breast milk. Specifically, the main unit serves as the pump's power source. The negative pressure within the air chamber 3a is precisely controlled through internal components such as the rotating shaft 4 and linkage 5 to tailor the suction efficiency to suit the user's comfort level. The connection between the air chamber 3a and the suction cup creates a negative pressure within the cup that facilitates suction. The cup is designed to fit snugly against the user's breast. The material and shape of the suction cup are carefully designed to ensure both effective transmission of negative pressure and a comfortable user experience during the suction process. A milk storage container collects and stores the breast milk extracted by the suction cup. The milk storage bottle has a wide mouth for easy cleaning and pouring, and is typically made of food-grade materials to ensure the safety and freshness of the breast milk.
