AI Technical Summary
Existing negative pressure physiotherapy robot cupping equipment has a high failure rate and unstable negative pressure value due to the frequent start and stop of the vacuum pump when controlling negative pressure, making it impossible to achieve stable cupping operation.
By employing a pressure sensor and solenoid valve in conjunction with a vacuum pump and throttle valve, the negative pressure is automatically adjusted by the solenoid valve and manually adjusted by the throttle valve, ensuring that the vacuum pump operates in a stable state and achieving controllable negative pressure.
Stable control of negative pressure was achieved, reducing the failure rate of the vacuum pump and improving the reliability and convenience of cupping operations.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of physiotherapy robot equipment, specifically relating to a cupping device with manually adjustable pressure air circuit structure. Background Technology
[0002] Cupping is a traditional Chinese medicine therapy that uses cups as tools and employs methods such as burning or suction to create negative pressure, causing the cups to adhere to the body surface and create local blood stasis. This is done to achieve effects such as clearing the meridians, promoting blood circulation, reducing swelling and pain, and dispelling wind and cold.
[0003] With the development of technology, the combination of cupping and collaborative robots—the negative pressure therapy robot—has become a reality. Compared with traditional cupping, the negative pressure therapy robot generates a vacuum through an air pump, heats the suction head through electric heating, and achieves fixed-point cupping and cupping through the precise movement of a six-axis collaborative robot. It is a more convenient and efficient form of cupping.
[0004] However, existing negative pressure physiotherapy robot cupping uses a vacuum pump that is constantly started and stopped to control the negative pressure. The vacuum pump will keep working until it reaches the preset pressure value, otherwise it will stop. This repeated starting and stopping will increase the failure rate of the vacuum pump, and the negative pressure value of the system will always be at the highest level. Utility Model Content
[0005] The purpose of this invention is to provide a manually adjustable pressure air circuit structure for cupping equipment to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A manually adjustable pressure cupping device air circuit structure includes a negative pressure head, a pressure sensor, a vacuum pump, a solenoid valve, and a throttle valve. The negative pressure head and the throttle valve are connected to a first air pipe connector via an air pipe, and the confluence end is connected to the air inlet of the vacuum pump via the air pipe to form a negative pressure air circuit. The solenoid valve is installed on the air pipe between the confluence end and the vacuum pump to form a negative pressure control air circuit. The pressure sensor is installed in conjunction with the negative pressure air circuit.
[0008] Preferably, the first air pipe connector, pressure sensor, solenoid valve and vacuum pump are all connected to the second air pipe connector through air pipes, and the second air pipe connector is a four-way connector.
[0009] Preferably, an oil filter is provided on the air pipe of the first air pipe connector and the air pipe of the pressure sensor.
[0010] Preferably, it further includes a first silencer, which is configured in conjunction with the solenoid valve.
[0011] Preferably, it further includes a second muffler, which is configured to cooperate with the throttle valve.
[0012] Preferably, a filter is provided at the outlet of the vacuum pump.
[0013] Preferably, the pressure sensor is a barometer.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] This invention automatically adjusts the negative pressure under different conditions by setting an electromagnetic valve, and the negative pressure of the vacuum pump can be adjusted by setting a throttle valve. The vacuum pump is always in a stable working state, which is safe and reliable, and can perform cupping and cupping operations. Attached Figure Description
[0016] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation
[0017] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0018] Reference Figure 1 A pressure-adjustable air circuit structure for cupping equipment includes a negative pressure head, a pressure sensor, a vacuum pump, a solenoid valve, a throttle valve, a first air pipe connector, and a second air pipe connector. The first air pipe connector is a three-way connector, and the second air pipe connector is a four-way connector. The negative pressure head and the throttle valve are connected to two ports of the three-way connector via air pipes, merging the two air paths. The merged air path is then connected to one port of the four-way connector via the third port of the three-way connector, delivering the merged air path to the four-way connector. The pressure sensor, the solenoid valve, and the vacuum pump are all connected to the other three ports of the four-way connector via air pipes. A filter is installed at the outlet of the vacuum pump.
[0019] The negative pressure head can be placed close to the skin to form a sealed cavity. When the vacuum pump is started, gas flows into the vacuum pump inlet from the negative pressure head and the throttle valve and is discharged from the vacuum pump outlet, forming a negative pressure air path. Since the negative pressure head and the human skin are sealed, negative pressure will be generated in the sealed cavity to achieve the purpose of cupping.
[0020] In this embodiment, the pressure generated by the vacuum pump can be adjusted while the vacuum pump is continuously operating by regulating the throttle valve. Furthermore, in emergency situations, the negative pressure can be manually released by fully opening the throttle valve. This throttle valve works in conjunction with a pressure sensor, which uses a barometer to detect and visualize the negative pressure value, facilitating operator adjustment of the throttle valve.
[0021] In this invention, the pressure sensor can also be of other forms, as long as it can display the system pressure value so that the pressure can be manually adjusted.
[0022] In this embodiment, a solenoid valve is installed in the negative pressure gas path. The solenoid valve and the vacuum pump form a negative pressure control gas path. The solenoid valve is connected to the controller to automatically control the generation and release of negative pressure, which facilitates the operation of the tank.
[0023] Furthermore, an oil filter is installed on the air pipe between the three-way connector and the four-way connector. The oil filter can adsorb oil and water in the discharged gas and filter the grease carried in the gas, preventing a large amount of grease from entering the vacuum pump with the gas.
[0024] Meanwhile, both the throttle valve and the solenoid valve are equipped with silencers at their inlet ends. The silencers can effectively reduce the noise when the throttle valve and the solenoid valve draw in gas, and can also prevent fine particles such as dust in the environment from entering, thus avoiding a reduction in service life due to particle entry.
