Description

Technical Field

[0001] This utility model relates to the field of air pump equipment technology, and in particular to an air pump with integrated pump and valve. Background Technology

[0002] Air pumps, as devices that provide gas power or create negative pressure, are widely used in medical equipment, analytical instruments, office automation, and industrial control, among other fields. As end products trend towards miniaturization, portability, and integration, the market places increasingly stringent demands on air pumps in terms of size, power consumption, and noise levels. To meet these requirements, integrated pump-valve design has become a crucial approach to air pump miniaturization. This design integrates the control valve and pump body into a compact unit, eliminating the need for external piping and separate valve installation space, effectively reducing leakage points, and improving system reliability.

[0003] However, in most existing integrated pump and valve air pump designs, the spatial layout of the air pump switching valve increases the size of the air pump in at least one dimension, which is not conducive to the overall miniaturization design. Utility Model Content

[0023] In existing technologies, the design and layout of most integrated pump and valve air pumps increase the size of the air pump in at least one dimension due to the spatial layout of the air pump switching valve, which is not conducive to the overall miniaturization design.

[0024] This utility model proposes a pump and valve integrated air pump.

[0025] Please see Figures 1 to 6 In one embodiment of this utility model, the pump-valve integrated air pump includes: a pump body, a connecting cap 300, a circuit board 400, and an air valve 500. The pump body includes a valve seat 100 and a valve plate 200, which together form an inlet chamber 110 and an outlet chamber 120. External gas flows into the inlet chamber 110 and from the inlet chamber 110 into the outlet chamber 120. The valve seat 100 is provided with a first air passage 130 and a first air outlet 131 communicating with the first air passage 130. An air outlet 131 is also connected to an air outlet chamber 120; a connecting cap 300 is connected to a valve seat 100, and the connecting cap 300 is provided with a connecting air passage, which is connected to the first air passage 130; a circuit board 400 is located on the valve seat 100; an air valve 500 is located on the circuit board 400, and the valve core movement direction of the air valve 500 is parallel to the circuit board 400. The air valve 500 is provided with an air inlet 520 and an air outlet 530. The connecting cap 300 is connected to the air inlet 520, and the air outlet 530 is used for air discharge.

[0026] Understandably, external gas enters the pump body and is delivered to the corresponding application product via the pump body, connecting cap 300, and air valve 500. In specific implementation, the pump body includes a valve seat 100 and a valve plate 200, with the valve seat 100 and valve plate 200 forming an inlet chamber 110 and an outlet chamber 120. The side of the valve seat 100 facing the valve plate 200 has a surrounding plate, which seals against the surface of the valve plate 200. Thus, the surrounding plate and the side wall of the valve seat 100, together with the valve plate 200, form the inlet chamber 110 and the outlet chamber 120. Further, a fixing post is provided on the side of the valve seat 100 away from the surrounding plate. The fixing post has a first air passage 130, and a first air outlet 131 is provided at a position corresponding to the first air passage 130 on the valve seat 100. The first air outlet 131 communicates with the outlet chamber 120. In this embodiment, the intake chamber 110 is connected to the outside. Specifically, the valve plate 200 has an opening connecting the intake chamber 110 and the outside, allowing outside air to enter the intake chamber 110. The intake chamber 110 is connected to the outlet chamber 120, allowing air to further enter the outlet chamber 120. In this embodiment, the extension direction of the first air passage 130 is perpendicular to the movement direction of the valve core inside the air valve 500. One end of the connecting cap 300 is inserted into the first air passage 130, and the other end is inserted into the air inlet 520 of the air valve 500, allowing gas to flow to the air valve 500 through the connecting passage of the connecting cap 300.

[0027] In the specific implementation process, the power supply and program status settings of the air pump are controlled by components on the circuit board 400. In this embodiment, the circuit board 400 is fixed to the valve seat 100 by screws, and the air valve 500 is fixed to the circuit board 400. The movement direction of the valve core of the air valve 500 is parallel to that of the circuit board 400, that is, as shown... Figure 1 As shown, the air valve 500 is arranged horizontally and connects to the first air passage 130 with the connecting cap 300, thereby reducing the extension space dimension of the air pump and facilitating miniaturization design. The air inlet 520 is arranged horizontally, and the air outlet 530 is set with the extension direction according to the design requirements. Furthermore, multiple air valves 500 can be provided, and multiple air valves 500 are arranged horizontally in sequence on the circuit board 400. Most of the components on the circuit board 400 are located on opposite sides of the air valves 500. In this way, the valve seat 100 has space to avoid the components, thereby reasonably arranging the components of the air pump, making the component arrangement of the air pump more compact and improving space utilization.

[0028] It should be noted that the airflow is driven by a drive mechanism within the pump body. External air enters the intake chamber 110 and, under the action of the drive mechanism, flows into the outlet chamber 120. The air chamber connects to the first air passage 130 via the first outlet 131. The first air passage 130 connects to the air valve 500 via the connecting cap 300, and is then discharged through the outlet 530 of the air valve 500. The drive mechanism uses a motor to drive a diaphragm or other structure capable of providing alternating negative pressure, thereby driving the airflow.

[0029] This utility model's technical solution uses a valve seat 100 and a valve plate 200 to form an air inlet chamber 110 and an air outlet chamber 120. External gas flows into the air inlet chamber 110 and then into the air outlet chamber 120. The valve seat 100 is also provided with a first air passage 130 and a first air outlet 131, so that the air outlet chamber 120 and the first air passage 130 are connected through the first air outlet 131. The air valve 500 is mounted on a circuit board 400, and the valve core moves according to the control of the components on the circuit board 400, thereby opening or closing the air valve 500. The movement direction of the valve core of the air valve 500 is parallel to the circuit board 400, that is, the air valve 500 is horizontally mounted on the circuit board 400, and it connects to the first air passage 130 with the connecting cap 300. This reduces the overall spatial layout of the air pump, thus facilitating the miniaturization of the air pump. Furthermore, the first air passage 130 is connected to the air valve 500 through the connecting air passage in the connecting cap 300. When the air pump discharges air, the gas enters the first air passage 130 from the air outlet 120 through the first air outlet 131, and further enters the air inlet 520 of the air valve 500 through the connecting air passage of the connecting cap 300, and finally is discharged from the air outlet 530 to the corresponding external product.

[0030] In one embodiment, the air valve 500 is provided with a first spring 510. One end of the first spring 510 is connected to the valve core of the air valve 500, and the other end is connected to the air inlet 520. The air valve 500 has an air outlet state and an air exhaust state. The air valve 500 is also provided with an exhaust nozzle 550. In the air outlet state, the first spring 510 drives the valve core to block the exhaust nozzle 550, and the air outlet 530 is connected to the air inlet 520. In the air exhaust state, the valve core moves to block the air inlet 520, and the air outlet 530 is connected to the exhaust nozzle 550. The valve seat 100 has an exhaust port 141, and the exhaust nozzle 550 is connected to the exhaust port 141.

[0031] The air pump provided in this embodiment has multiple states, thereby achieving various effects. Specifically, in this embodiment, it can be understood that the air valve 500 has an internal channel, the valve core moves within the channel, and there is a gap between the valve core and the inner wall of the channel to achieve airflow. The inlet nozzle 520 and the outlet nozzle 530 are both connected to the channel, thereby achieving airflow. The first spring 510 is located within the channel, and one end of the first spring 510 is connected to the valve core, and the other end is connected to the inlet nozzle 520. Further, the air valve 500 also has an exhaust nozzle 550, which is connected to the channel, and the exhaust nozzle 550 and the inlet nozzle 520 are located at opposite ends of the channel. In addition, the valve seat 100 has an exhaust port 141, which is connected to the outside. There is also a cavity between the valve seat 100 and the circuit board 400, which is connected to the exhaust port 141 and the exhaust nozzle 550. The airflow discharged from the exhaust nozzle 550 enters the cavity and is further discharged to the outside through the exhaust port 141.

[0032] Specifically, in the air-out state, the valve core, under the action of the first spring 510, abuts against the exhaust nozzle 550 and blocks the exhaust nozzle 550. At this time, the airflow flowing in from the air inlet 520 is discharged through the air outlet 530 and flows into the product to complete the corresponding function. In the air-exhaust state, the valve core is driven to move towards the air inlet 520, opening the exhaust nozzle 550 and blocking the air inlet 520. Under the action of air pressure, the gas inside the product flows in through the air outlet 530 and is directly discharged through the exhaust nozzle 550, thereby achieving the exhaust function.

[0033] The valve core of the air valve 500 can be moved by a motor or manually, or by a drive structure. In one embodiment, the valve core moves by electromagnetic drive. Specifically, the air valve 500 is equipped with an electromagnetic coil 560, the valve core of the air valve 500 is made of magnetic metal, the electromagnetic coil 560 is wound around the outer circumference of the valve core, and the electromagnetic coil 560 is energized to drive the valve core of the air valve 500 to move and block the air inlet 520.

[0034] In the specific implementation process, the valve core is a movable iron core 540, and an electromagnetic coil 560 is wound around the outer periphery of the air valve 500 channel and arranged around the valve core. When the electromagnetic coil 560 is energized, it generates a magnetic field. Under the action of the magnetic field, the movable iron core 540 moves towards the air inlet 520 and compresses the first spring 510, thereby blocking the air inlet 520 and opening the exhaust port 550 at the same time. At this time, the pump body is in a de-energized state, while the air valve 500 is in an energized state.

[0035] In one embodiment, the air pump further includes a check valve 600, which is disposed in the first air passage 130 and cooperates with the first air outlet 131 to control the opening and closing of the air outlet chamber 120 and the first air passage 130.

[0036] In the specific implementation process, the check valve 600 is movably disposed within the first air passage 130 and is used to open or block the first air outlet 131. Specifically, in the air outlet state, the gas in the air outlet chamber 120 passes through the first air outlet 131 and drives the check valve 600 to move away from the first air outlet 131, and the airflow enters the first air passage 130 through the first air outlet 131. The air pump also has a pressure holding state. Specifically, the check valve 600 moves away from the air inlet 520 and approaches the first air outlet 131, blocking the first air outlet 131. At this time, the pump body is in a de-energized state, and the gas in the product cannot enter the pump body, thereby achieving the pressure holding effect. The check valve 600 can be moved by a motor or other drive mechanism or manually to block the first air outlet 131.

[0037] Furthermore, in one embodiment, the check valve 600 is connected to a second spring 610, which is in contact with the connecting cap 300. The second spring 610 has a tendency to drive the check valve 600 to block the first air outlet 131. In specific implementation, the check valve 600 abuts against the valve seat 100 and blocks the first air outlet 131 under the action of the second spring 610. In addition, in the air outlet state, the airflow of the air outlet chamber 120 passes through the first air outlet 131 and overcomes the elastic force of the second spring 610 to push the check valve 600 to move away and open the first air outlet 131.

[0038] In one embodiment, multiple air valves 500 are provided and arranged sequentially along the circuit board 400. A check valve 600 is provided in a one-to-one correspondence with each of the multiple air valves 500, and a first air passage 130 corresponds to each check valve 600. Multiple connecting caps 300 are integrally formed. Specifically, the multiple air valves 500 can increase the air output volume and output pressure of the air pump to meet different needs. In a specific implementation, the multiple air valves 500 are arranged side-by-side on the circuit board 400, and the air valves 500, connecting caps 300, and check valves 600 correspond one-to-one. This embodiment uses three valves as an example. Specifically, three air valves 500 are arranged in parallel and fixedly mounted on the circuit board 400. Each air valve 500 is connected to a corresponding connecting cap 300, which in turn is connected to a corresponding first air passage 130. Each of the three first air passages 130 has a first air outlet 131, which communicates with an air outlet chamber 120. The distribution of the three connecting caps 300, the first air passages 130, and the first air outlets 131 is designed according to actual requirements. Furthermore, for ease of installation, the three connecting caps 300 are integrally formed, which also improves their strength.

[0039] refer to Figure 2 and Figure 5As shown, in one embodiment, the air pump further includes a pressure regulating valve 700. The valve seat 100 is provided with a second air passage 150 and a second air outlet 151 communicating with the second air passage 150. The second air outlet 151 is also communicating with the air outlet chamber 120. The pressure regulating valve 700 is provided in the second air passage 150 and is used to control the opening and closing of the second air outlet 151.

[0040] Specifically, when the air pump is working, the flow rate is large and the pressure is high. The pressure regulating valve 700 is connected to the air outlet chamber 120. After adjusting the pressure required by the air pump, when the air pump pressure reaches a certain value, the spring in the pressure regulating valve 700 compresses the gas pressure and appropriately releases the gas in the air outlet chamber 120 to reduce the pressure and ensure that the air pump pressure is stable within a certain range. In this embodiment, the valve seat 100 forms an exhaust chamber 140 on the side opposite to the air outlet chamber 120 and cooperates with the circuit board 400. The exhaust chamber 140 is connected to the outside through the exhaust port 141. The valve seat 100 is provided with a fixing post, and a second air passage 150 is opened in the fixing post. The valve seat 100 is also provided with a second air outlet 151. The second air passage 150 is connected to the air outlet chamber 120 through the second air outlet 151. The pressure regulating valve 700 is located in the second air passage 150 and is screwed and fixedly connected to the second air passage 150. When the pressure in the outlet chamber 120 is greater than the preset pressure of the pressure regulating valve 700, the airflow pushes the valve core of the pressure regulating valve 700 to move and compress the spring through the second outlet 151, thereby opening the second outlet 151. The airflow enters the second air passage 150 and further enters the exhaust chamber 140, and is discharged through the exhaust port 141.

[0041] In one embodiment, the air pump further includes a base assembly 800, a valve plate seat 210, a tower bladder, and a drive motor 820 disposed on the base assembly 800. The base assembly 800 has a mounting cavity 810, and the tower bladder is disposed in the mounting cavity 810. The drive motor 820 drives and connects to a rocker arm 830, which is connected to the tower bladder. The valve plate 200 is disposed on the valve plate seat 210, and both have corresponding first ports 220, second ports 230, and third ports 240. The inner cavity of the tower bladder is connected to the air inlet chamber 110 through the first port 220, and the inner cavity of the tower bladder is also connected to the air outlet chamber 120 through the second port 230. The first port 220 of the valve seat 100 is provided with a first one-way valve 250, and the second port 230 of the valve plate 200 is provided with a second one-way valve 260. The air inlet chamber 110 is connected to the mounting cavity 810 through the third port 240, and the mounting cavity 810 is connected to the outside.

[0042] It should be noted that the valve plate 200 is installed on the side of the valve plate seat 210 facing the valve seat 100. The valve plate seat 210 and the valve plate 200 have corresponding openings of a first port 220, a second port 230, and a third port 240 to facilitate airflow. A first one-way valve 250 is installed on the valve plate seat 210, and a second one-way valve 260 is located on the valve plate 200 and cooperates with the valve plate seat 210 to block the second port 230. Specifically, the drive motor 820 is fixedly installed on the base assembly 800. The drive motor 820 is connected to an eccentric wheel, which is connected to a rocker arm 830. The rocker arm 830 is connected to the tower bladder, thereby driving the tower bladder to compress. The base assembly 800 has an installation cavity 810, the tower bag is disposed in the installation cavity 810, and the tower bag is also in contact with the valve plate seat 210. It can be understood that the tower bag has an inner cavity, which is connected to the gas outlet cavity 120 through the first port 220 and the second port 230, and the inner cavity is also connected to the installation cavity 810 through the third port 240. In this way, the tower bladder is compressed, causing its inner cavity to be compressed. The first one-way valve 250 opens, and the airflow in the inner cavity flows into the outlet chamber 120 through the first port 220. Meanwhile, the second port 230 is blocked by the second one-way valve 260. At the same time, the air pressure in the mounting chamber 810 decreases, and external airflow enters the mounting chamber 810. When the tower bladder is reset, the second one-way valve 260 opens, and the airflow in the inlet chamber 110 enters the inner cavity of the tower bladder through the second port 230. The first port 220 is blocked by the first one-way valve 250, and the air pressure in the inlet chamber 110 decreases. The airflow in the mounting chamber 810 enters the inlet chamber 110 through the third port 240, thus realizing the flow of airflow. Specifically, when the tower bladder is compressed, the first one-way valve 250 is configured as a baffle connected to the valve plate 200. Under the impact of the airflow, the baffle is blown away from the valve plate seat 210, allowing the airflow to enter the outlet chamber 120. When the tower bladder is reset, the airflow in the inlet chamber 110 presses against the first one-way valve 250, pressing the first one-way valve 250 tightly against the valve plate seat 210, thereby blocking the first port 220.

[0043] In one embodiment, the base assembly 800 includes a tower bag seat 840 and a fixed seat 850. The valve plate seat 210 is connected to the tower bag seat 840 and clamps the tower bag. The drive motor 820 and the tower bag seat 840 are respectively disposed on the fixed seat 850. The tower bag seat 840 and the fixed seat 850 form an installation cavity 810. The tower bag seat 840 has a fourth port 841 that connects the air inlet cavity 110 and the installation cavity 810. The fixed seat 850 is provided with a vent 851 that connects the installation cavity 810 and the outside.

[0044] To facilitate the installation of the tower bladder, in practice, the base assembly 800 includes a detachably connected tower bladder seat 840 and a fixed seat 850. A drive motor 820 is mounted on the fixed seat 850. The tower bladder seat 840 and the fixed seat 850 are connected by screws or snap-fit. The tower bladder has a flange, and the tower bladder seat 840 clamps the flange with the valve plate seat 210 to fix the tower bladder. Furthermore, the tower bladder seat 840 also has an opening for fixing the tower bladder, thus restricting its circumferential movement. External air enters the mounting cavity 810 through the vent 851. A fourth opening 841 connects the air inlet cavity 110 and the mounting cavity 810, enabling airflow.

[0045] In one embodiment, the air pump further includes a fixing cover 900, which is snap-fitted to the valve seat 100. The fixing cover 900 is provided with a protective tube, and the air outlet 530 is movably inserted into the protective tube. In specific implementation, the fixing cover 900 and the valve seat 100 are connected by snap-fit ​​for easy assembly. The fixing cover 900 is used to cover the air valve 500, circuit board 400, and connecting cover, and the protective tube is provided to accommodate the air outlet 530.

[0046] During the air pump intake phase: The drive motor 820 is energized and rotates the eccentric wheel, which pulls the tower chamber to one side via the swing arm 830. As the volume of the tower chamber increases, the internal pressure decreases (negative pressure), and the one-way valve at the second port 230 opens (the one-way valve at the second port 230 closes). Gas in the intake chamber 110 is drawn into the inner cavity. Simultaneously, external air enters the mounting cavity 810 and further into the intake chamber 110. During the exhaust phase: The drive motor 820 drives the swing arm 830 to move the tower chamber, causing the volume of the tower chamber to decrease and the pressure to increase (positive pressure). The one-way valve at the second port 230 closes, and the one-way valve at the first port 220 opens, forcing gas out and allowing it to enter the exhaust chamber 120 through the first port 220.

[0047] In practical implementation, when the pump body is energized (drive motor 820 is energized), the air valve 500 is not energized. The circuit board 400 controls the inflation of the finished product. At this time, the movable iron core 540 of the air valve 500 opens the air inlet 520 and closes the exhaust port 550 under the action of the first spring 510. Gas flows into the air valve 500 from the exhaust chamber 120 and is discharged into the finished product machine through the air valve 500 to perform work. When the pump body is de-energized, the check valve 600 rebounds and closes the first air outlet 131 under the action of the second spring 610, preventing gas from entering the exhaust chamber 120 through the first air outlet 131, thus playing the role of maintaining gas pressure. When the pump body is de-energized and the air valve 500 is energized, the movable iron core 540 compresses the first spring 510 under the action of electromagnetic force, opens the exhaust port 550, and simultaneously blocks the air inlet 520. Gas in the finished product is discharged through the exhaust port 141.

Any equivalent structural transformations made based on the inventive concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
