Description

Technical Field

[0001] This utility model belongs to the technical field of electric cupping devices, specifically relating to an electric cupping device that can maintain pressure continuously. Background Technology

[0002] Electric cupping devices often require maintaining negative pressure within the cups to achieve negative pressure cupping. However, existing products are prone to air backflow in their negative pressure air pumps, preventing the cups from maintaining a constant negative pressure for extended periods. This necessitates the air pump constantly restarting and replenishing the negative pressure during cupping or scraping. This constant restarting increases noise and reduces the pump's lifespan. The main reason for this inconsistent negative pressure is that the air pump head cannot lock in air when not in use, allowing for bidirectional airflow. After the pump stops for a period, air can easily be drawn back into the cups through the pump head, causing negative pressure loss. To prevent this backflow, it is necessary to design an electric cupping device that can maintain continuous pressure. Utility Model Content

[0003] To address the aforementioned problems in existing technologies, this solution provides a continuously pressure-maintaining electric cupping device.

[0004] The technical solution adopted in this utility model is as follows:

[0005] An electric cupping device with sustainable pressure maintenance includes a cup and an air suction device; the connector of the cup is detachably connected to the connection port at the bottom of the air suction device, and an air hole is provided at the connection port at the bottom of the air suction device; after the cup is connected to the air suction device, the air hole can suck air out of the cup.

[0006] The air extraction device includes an outer casing, within which are housed a negative pressure air pump, a solenoid valve, a multi-port connector, a one-way valve, and a turbulence silencer. The negative pressure air pump is fixed to the inner bottom of the outer casing. The air inlet of the negative pressure air pump is connected to the one-way valve, and the air outlet of the negative pressure air pump is connected to the turbulence silencer and also connected to the exhaust chamber of the turbulence silencer. The first port of the multi-port connector is connected to the one-way valve, the second port is connected to an air vent, the third port is connected to the solenoid valve, and the fourth port is connected to a pneumatic pressure sensor.

[0007] As an alternative or supplement to the above solution: the multi-interface connector is a four-way connector, and the four interfaces of the multi-interface connector are arranged in a cross shape.

[0008] As an alternative or supplement to the above solution: the solenoid valve, multi-port connector, and one-way valve are arranged in a straight line on the side of the negative pressure air pump.

[0009] As an alternative or supplement to the above solution: the turbulence muffler is provided with an air inlet and an air intake hole, and the air inlet and the air intake hole are connected through the internal drainage channel of the turbulence muffler; the air inlet is located at the head of the negative pressure air pump and is connected to the air intake end of the negative pressure air pump; the air intake hole is located on the outside of the negative pressure air pump and is connected to the one-way valve.

[0010] As an alternative or supplement to the above scheme: the walls of the exhaust chamber are provided with several cylindrical protrusions and prismatic protrusions, which are used to slow down the air in the exhaust chamber.

[0011] As an alternative or supplement to the above solution: the corner of the turbulence muffler is provided with an arc-shaped extension arm, the lower side of the extension arm is provided with a groove-shaped turbulence channel, and a turbulence plate is provided in the turbulence channel.

[0012] As an alternative or supplement to the above solution: the extension arm extends below the check valve.

[0013] The beneficial effects of this utility model are as follows: In this solution, a one-way valve is installed on the air inlet side of the negative pressure air pump.

Detailed Implementation

[0022] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only a part of the embodiments, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments in this solution without creative effort are within the protection scope of this solution.

[0023] like Figures 1 to 6 As shown, this embodiment designs a continuously pressurized electric cupping device, including a cup 6 and an air extraction device. The cup 6 has a connector, and the bottom of the air extraction device has a connection port 51 that engages with the connector. The connector of the cup 6 and the connection port 51 at the bottom of the air extraction device are connected in a snap-fit ​​structure to achieve a detachable connection. An air hole is provided at the connection port 51 at the bottom of the air extraction device. After the cup 6 is connected to the air extraction device, the negative pressure air pump 4 inside the air extraction device can draw air from inside the cup 6 through the air hole.

[0024] The air extraction device includes a cylindrical outer casing 5. Inside the casing 5 are components such as a negative pressure air pump 4, a solenoid valve 3, a multi-port connector, a one-way valve 10, and a turbulence silencer 8. An end cap 1 is located on the top of the casing 5, which closes the casing 5. A main control board 2 is located at the center of the end cap 1. The main control board 2 is connected to and powered by a battery. A charging port can also be provided on the main control board 2 to charge the battery. The main control board 2 controls the power supply to the negative pressure air pump 4 and the opening and closing of the solenoid valve 3. Buttons are provided on the main control board 2 for button operation and parameter setting.

[0025] The negative pressure air pump 4 is fixed to the inner bottom of the outer shell 5; the fixing bracket 7 is connected to the inner bottom of the outer shell 5, thereby pressing and fixing the negative pressure air pump 44 to the inner bottom of the outer shell 55, improving the stability of the negative pressure air pump 44 after installation and reducing the vibration generated by the negative pressure air pump 44 during operation.

[0026] The air inlet of the negative pressure air pump 4 is connected to the one-way valve 10. The one-way valve 10 allows for one-way airflow and maintains the flow of air from the four-way valve 9 to the negative pressure air pump 4. At the same time, the one-way valve 10 also reduces the backflow of air from the negative pressure air pump 4 to the four-way valve 9, thereby reducing the rate of negative pressure loss in the container 6.

[0027] The outlet of the negative pressure air pump 4 is connected to the turbulence silencer 8 and communicates with the exhaust chamber 84 of the turbulence silencer 8. The first port of the multi-port connector is connected to the one-way valve 10, the second port is connected to the air hole at the bottom of the housing 5, the third port is connected to the solenoid valve 3, and the fourth port is connected to the pneumatic pressure sensor. When the multi-port connector is a four-way connector 9, the four ports of the multi-port connector are arranged in a cross shape. The pneumatic pressure sensor is connected to a microcontroller such as the MCU on the main control board 2 through an analog-to-digital converter, thereby feeding back the air pressure value measured by the pneumatic pressure sensor.

[0028] The solenoid valve 3, multi-port connector, and one-way valve 10 are arranged in a straight line on the side of the negative pressure air pump 4. This layout optimizes the airflow path, improves the smoothness of airflow, makes the space more compact, reduces the use of curved pipes, and avoids noise generated when air flows through curved pipes.

[0029] The turbulence muffler 8 is equipped with an air inlet 82 and an air intake hole 83. An internal flow channel is provided within the turbulence muffler 8, and the air inlet 82 communicates with the flow channel of the air intake hole 83. The air inlet 82 is located at the head of the negative pressure air pump 4 and communicates with the air inlet end of the negative pressure air pump 4. The air intake hole 83 is located on the outside of the negative pressure air pump 4 and is connected to the one-way valve 10. This structure, through the independent flow channel on the turbulence muffler 8, achieves airflow guidance, avoiding the waste of resources and space caused by using both a flexible hose and the turbulence muffler 8 in a confined space. It simplifies the airflow structure, improves the convenience of assembly and maintenance, and also allows the vibration generated by the intake of the negative pressure air pump 4 to partially cancel out the vibration generated by the exhaust, thereby reducing vibration and noise.

[0030] The walls of the exhaust chamber 84 are provided with several cylindrical and prismatic protrusions, which are used to slow down the air in the exhaust chamber 84. These protrusions can slow down the air in the exhaust chamber 84, thereby avoiding noise caused by excessive air speed.

[0031] The turbulence muffler 8 has an arc-shaped extension arm 81 at its corner, which extends to the bottom of the one-way valve 10. The lower side of the extension arm 81 has a groove-shaped turbulence channel with the groove opening facing downwards and directly opposite the exhaust port on the outer casing 5. This allows gas to be discharged from any position of the groove opening to the outside of the outer casing 5. Several turbulence deflectors 85 are provided in the turbulence channel, which can further decelerate the air and reduce noise.

[0032] When in use, with solenoid valve 3 closed and negative pressure air pump 4 activated, air in cup 6 is continuously drawn out. The air passes sequentially through the vent at the bottom of the outer casing, the four-way valve 9, the one-way valve 10, the negative pressure air pump 4, and the turbulence silencer 8 before being discharged outside the outer casing 5. When solenoid valve 3 is closed and negative pressure air pump 4 stops, the one-way valve 10 prevents air from flowing back from the negative pressure air pump 4, thus maintaining continuous pressure in cup 6. When solenoid valve 3 is open and negative pressure air pump 4 stops, air from the atmosphere can flow through solenoid valve 3, the four-way valve 9, and the vent at the bottom of the outer casing into cup 6, facilitating the removal of the electric cupping device or changing the cupping position.

[0033] Because the one-way valve 10 prevents air from flowing back from the negative pressure pump 4, the cup 6 can maintain negative pressure for a long time, reducing the number of times the negative pressure pump 4 is repeatedly started, thereby extending the service life of the electric cupping device.

[0034] The above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation; it is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom remain within the scope of this technology.
