[0023] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0024] Please refer to Figures 1-5 This embodiment provides a pumping device 100, which includes an air guiding body 110, a movable cylinder 120, a drive assembly 130, and a valve body assembly 140. The air guide body 110 has an air chamber 111, an air inlet 112, an air outlet 113, an air inlet passage 114, and an air outlet passage 115; the air inlet 112 is connected to the air inlet passage 114, and the air outlet 113 is connected to the air outlet passage 115. The movable cylinder 120 is movably connected to the air chamber 111 and is connected in a transmission manner to the drive assembly 130 connected to the air guide body 110. The valve body assembly 140 is connected to the air guide body 110, and the valve body assembly 140 is used to enable one of the intake air passage 114 and the exhaust air passage 115 to communicate with the air chamber 111.

[0025] Please refer to Figures 1-5 The working principle of the air pump 100 is as follows: The air pumping device 100 includes an air guiding body 110, a movable cylinder 120, a drive assembly 130, and a valve body assembly 140. The air guide body 110 has an air chamber 111, an air inlet 112, an air outlet 113, an air intake passage 114, and an air exhaust passage 115. The air inlet 112 is connected to the air intake passage 114, and the air outlet 113 is connected to the air exhaust passage 115. The movable cylinder 120 is movably connected to the air chamber 111 and is driven by the drive assembly 130 connected to the air guide body 110. The valve body assembly 140 is connected to the air guide body 110 and is used to make one of the air intake passage 114 and the air exhaust passage 115 communicate with the air chamber 111.

[0026] Therefore, the pumping device 100 can drive the movable cylinder 120 to move relative to the air chamber 111 through the drive component 130, thereby changing the volume of the air chamber 111 so that the internal volume of the air chamber 111 increases or decreases. When its internal volume increases, it corresponds to the pumping process, and when its internal volume decreases, it corresponds to the exhaust process or the pressurization process. Furthermore, the air guide body 110 is provided with an air inlet 112, an air outlet 113, an air inlet passage 114, and an air outlet passage 115, with the air inlet 112 connected to the air inlet passage 114 and the air outlet 113 connected to the air outlet passage 115. To facilitate both suction and exhaust, one of the air inlet passage 114 and the air outlet passage 115 can be connected to the air chamber 111 via the valve body assembly 140, thereby connecting the air inlet passage 114 to the air chamber 111 via the valve body assembly 140. When the drive assembly 130 is in operation, the volume of the air chamber 111 increases, and the airflow can be introduced into the air chamber 111 through the air inlet 112 and the air inlet passage 114; when the valve body assembly 140 connects the exhaust passage 115 with the air chamber 111, the volume of the air chamber 111 decreases under the drive of the drive assembly 130, and the airflow in the air chamber 111 can be discharged through the exhaust passage 115 and the exhaust port 113, and discharged through the air nozzle 170 connected to the exhaust port 113. Therefore, as can be seen from the above, the air pumping device 100 can reduce its overall structural volume while ensuring its air pumping function by setting up its internal air inlet 112, air outlet 113, air inlet passage 114, and air outlet passage 115, as well as the setting of the movable cylinder 120, drive assembly 130, and valve body assembly 140. Furthermore, adjusting the size of the air inlet 112, air outlet 113, air inlet passage 114, and air outlet passage 115 is beneficial for adjusting its pressure. The smaller the inherent volume inside the device, the less the impact on the pressure change in the pressure container connected to the air nozzle 170, which helps to improve the adjustment accuracy and measurement accuracy. In summary, the pumping device 100 has a simple structure, is easy to assemble, has high adjustment accuracy, and has a small overall size, making it easy to install on portable devices.

[0027] Further, please refer to Figures 1-5In this embodiment, as can be seen from the above, the pumping device 100 switches the connection between the air intake passage 114 and the exhaust passage 115 and the air chamber 111 through the valve body assembly 140. In addition, in order to reduce the number of air passages in the air guide body 110, an air guide passage 116 is also provided in the air guide body 110, which is connected to the air chamber 111. The valve body assembly 140 is used to connect one of the air intake passage 114 and the exhaust passage 115 to the air guide passage 116. That is, by setting the aforementioned air guide passage 116, the valve body assembly 140 can connect one of the intake air passage 114 and the exhaust air passage 115 to the air guide passage 116. Therefore, the air guide body 110 is equipped with an air passage shared by the air extraction and exhaust processes, thereby optimizing the air passage setting. This avoids the method of directly connecting the two ends of the intake air passage 114 to the air chamber 111 and the air inlet 112, and directly connecting the two ends of the exhaust air passage 115 to the air chamber 111 and the exhaust port 113. This helps to reduce the length of the air passage and the exhaust air passage 115, thereby reducing the length of the air passage in the air guide body 110, simplifying the structure of the air guide body 110, and improving control accuracy.

[0028] Furthermore, during the exhaust process, in order to adjust its output pressure, the pressure is monitored and coordinated with the drive component 130 to form a closed-loop control for pressure monitoring and adjustment, thereby achieving precise pressure control and adjustment. Specifically, the air pumping device 100 also includes a pressure detection component 150 connected to the air guide body 110. The air guide body 110 also has a pressure detection passage 117, which is connected to the exhaust air passage 115, and the pressure detection component 150 is connected to the pressure detection passage 117.

[0029] With the above-described structural configuration, since the pressure detection passage 117 is connected to the exhaust gas passage 115, the gas passage configuration can be optimized. The pressure in the exhaust gas passage 115 can be monitored through the pressure detection component 150 connected to the pressure detection passage 117, thereby achieving exhaust pressure monitoring. Then, the drive component 130 can be controlled and adjusted according to the pressure monitoring results, thus achieving closed-loop control of monitoring and adjustment, and thus achieving precise pressure control and adjustment.

[0030] Further, please refer to Figures 1-5Based on the above, it can be seen that an intake air passage 114, an exhaust air passage 115, an air guide passage 116, and a pressure detection passage 117 are provided inside the air guide body 110. On this basis, with the dimensions of the intake port 112 and the exhaust port 113 adapted to the inner diameter of the intake air passage 114 and the exhaust air passage 115, the diameter of the intake air passage 114, the exhaust air passage 115, the air guide passage 116, and the pressure detection passage 117 can all be less than 0.8 mm. This can help reduce the volume of the air passage inside the air guide body 110, thereby avoiding the influence of excessive airflow margin in the air passage on the airflow pressure during the exhaust process, and improving the accuracy of pressure monitoring.

[0031] It should be noted that in this embodiment, the diameter of the intake air passage 114, exhaust air passage 115, air guide passage 116 and pressure detection passage 117 is set to 0.5mm. In other embodiments of this utility model, the size can be set to 0.4mm, 0.6mm or 0.7mm.

[0032] Further, please refer to Figures 1-5 As can be seen from the above, the valve body assembly 140 is configured to allow one of the intake air passage 114 and the exhaust air passage 115 to be connected to the air chamber 111. Moreover, based on the above-mentioned configuration of the air guide passage 116, the function of the valve body assembly 140 is to allow one of the intake air passage 114 and the exhaust air passage 115 to be connected to the air guide passage 116. Therefore, in order to adjust the state of the connection between the intake air passage 114 and the exhaust air passage 115 and the air guide passage 116 according to the working state of the pumping device 100, the valve body assembly 140 is configured to include a first solenoid valve 141 and a second solenoid valve 142. Specifically, both the first solenoid valve 141 and the second solenoid valve 142 are connected to the air guide body 110. The first solenoid valve 141 is used to connect or block the intake air passage 114 and the air guide passage 116, and the second solenoid valve 142 is used to connect or block the exhaust air passage 115 and the air guide passage 116.

[0033] Therefore, during the air extraction process, the first solenoid valve 141 can connect the air intake passage 114 and the air guide passage 116, so that the airflow can be introduced into the air chamber 111 through the air intake hole 112, the air intake passage 114 and the air guide passage 116. During this process, the second solenoid valve 142 can be in an open state. That is, the second solenoid valve 142 blocks the exhaust air passage 115 from the guide air passage 116, so that the airflow in the intake air passage 114 can only be introduced into the air chamber 111 through the guide air passage 116, while the airflow in the intake air passage 114 cannot be introduced into the exhaust air passage 115, and the airflow introduced through the exhaust port 113 cannot be introduced into the air chamber 111 after entering the exhaust air passage 115. It should be noted that the state of the second solenoid valve 142 during the air extraction process can be adjusted according to the usage requirements.

[0034] During the exhaust process, the second solenoid valve 142 connects the exhaust passage 115 with the guide passage 116, allowing the airflow in the air chamber 111 to pass through the guide passage 116 and the exhaust passage 115 before being discharged through the exhaust port 113. During this process, the first solenoid valve 141 disconnects the intake passage 114 from the guide passage 116, preventing the airflow discharged through the guide passage 116 from being discharged through the intake passage 114 and the intake port 112. This ensures the stability of the exhaust process and the exhaust pressure.

[0035] Based on the above structure, during the process of suction and exhaust, the moving cylinder 120 is driven by the drive assembly 130 to move relative to the air chamber 111, thereby increasing or decreasing the volume of the air chamber 111. Based on this, when configuring the drive assembly 130, the drive assembly 130 may include a drive motor 131 and a drive rod 132. The drive motor 131 is connected to the air guide body 110. The two ends of the drive rod 132 are respectively connected to the output end of the drive motor 131 and the movable cylinder 120. The drive rod 132 is used to drive the movable cylinder 120 to move along the axis of the air chamber 111 under the driving action of the drive motor 131.

[0036] It should be noted that, as mentioned above, when the movable cylinder 120 moves relative to the air chamber 111, its purpose is to change the volume of the air chamber 111. Therefore, this embodiment adopts the method of linear movement of the movable cylinder 120 relative to the air chamber 111. Based on this, when the drive motor 131 drives the drive rod 132 to move, in order to enable the drive rod 132 to achieve linear movement based on its connection with the movable cylinder 120, the movement form of the output end of the drive motor 131 is also linear movement.

[0037] Therefore, with the above-mentioned structural configuration, the drive rod 132 can be driven by the drive motor 131 to move, thereby driving the drive cylinder to move relative to the air chamber 111. In this process, the exhaust pressure can be adjusted and the amount of gas drawn in and discharged from the air chamber 111 can be controlled by controlling the drive motor 131.

[0038] Please refer to Figures 1-5 Based on the aforementioned structure of the drive motor 131, to enable its output end to be connected to the movable cylinder 120 for transmission, the drive assembly 130 also includes a universal joint 133. The drive motor 131 is a stepper motor, and its output end is connected to the drive rod 132 via the universal joint 133. This facilitates the movement of the drive rod 132 and the movable cylinder 120 through the operation of the stepper motor.

[0039] Further, please refer to Figures 1-5 As can be seen from the above, this embodiment uses the drive component 130 to realize the air extraction and exhaust action. In this process, in order to adjust the air flow rate and air pressure of the air extraction and exhaust, the air pumping device 100 also includes a displacement monitoring component 160 and a monitoring rod 161. The displacement monitoring component 160 is connected to the air guide body 110, and the monitoring rod 161 is connected to the universal joint 133. The displacement monitoring component 160 is used to monitor the movement of the monitoring rod 161 along the axis of the air chamber 111.

[0040] Therefore, with the above-described structural configuration, the movement of the monitoring rod 161 along the axis of the air chamber 111 can be detected by the displacement monitoring component 160. Since the monitoring rod 161 is connected to the universal joint 133, and the universal joint 133 is connected to the drive rod 132, the movements of the monitoring rod 161, the universal joint 133, the drive rod 132, and the movable cylinder 120 are synchronized. Thus, by detecting the movement of the monitoring rod 161 along the axis of the air chamber 111, the movement of the movable cylinder 120 relative to the axis of the air chamber 111 can be determined. Based on the pressure detection of the aforementioned pressure detection component 150, closed-loop pressure control can be achieved by controlling the drive motor 131, and the flow rate and total amount of airflow drawn in and discharged can be adjusted and controlled.

[0041] To guide the movement of the universal joint 133, the air guide body 110 is provided with a movable channel 118 for the drive rod 132 and the universal joint 133 to move. To avoid interference between the movement of the monitoring rod 161 and the movable channel 118, a groove 119 is provided on the side of the movable channel 118 facing the displacement monitoring component 160 for the monitoring rod 161 to pass through.

[0042] It should be noted that this embodiment is also equipped with a control module 180, which is electrically connected to the valve body assembly 140, pressure detection assembly 150, drive assembly 130 and displacement monitoring assembly 160 mentioned above. The structure of the control module 180 can adopt the circuit board and controller structure of the prior art, which will not be described in detail here.

[0043] In summary, please refer to Figures 1-5The pumping device 100 has at least the following advantages: The volume of the air passage inside the air guide body 110 is reduced, allowing the external pressure device to obtain greater pressure; the external size is reduced, making the structure simple and compact, and easier to install on small or portable devices; by directly embedding the device in the terminal, the pressure value can be obtained in real time, and in conjunction with the drive component 130, negative feedback regulation is formed, making the pressure adjustment more precise.

[0044] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
