Description

Technical Field

[0001] The utility model relates to the field of electric cupping devices, in particular to a negative pressure precision control device for electric cupping devices. Background Art

[0002] While electric cupping devices currently on the market have significantly simplified the cupping procedure by replacing ignition with electric vacuum extraction, they still have some drawbacks. Typical drawbacks include insufficient precision in negative pressure control, large negative pressure fluctuations, continuous vacuum pump operation, noise pollution, inability to automatically maintain pressure, and the inability to implement surge and pulse cupping functions.

[0003] The main reason is that the system negative pressure cannot be accurately controlled.

[0004] Typical prior art, such as CN 110339037A, discloses an intelligent cupping system and its control method, belonging to the field of cupping therapy technology. The system includes a cup body, a main control module, a negative pressure module, a light therapy module, a power supply module, a cloud server, and an intelligent terminal. The main control module is in communication with the cloud server and the intelligent terminal. The system mainly solves the problem of cloud control and remote control. Although it has corresponding modules, it does not improve the precise control of negative pressure.

[0005] Another example is CN210963279U, which discloses a constant-pressure, timed vacuum cupping device. This device incorporates a constant-pressure, timed vacuum control box attached to a conventional cupping device. Multiple cupping devices are connected to a hose reel via hoses, which in turn are connected to the control box via a stainless steel vacuum tube. The control box is divided into three sections: a vacuum pump, which houses a vacuum pump connecting the vacuum tube to the control panel; a controller, which houses a control panel including a timer, air pressure sensor, and pump controller; a power switch, a timer reset button, and negative pressure increase / decrease buttons; and a liquid crystal display (LCD) display, which includes a timing panel and a pressure panel. While this device achieves varying vacuum levels for cupping and is easy to operate, it still requires frequent starting and stopping of the vacuum pump for constant pressure control, which increases the noise level and reduces its lifespan.

[0006] Based on the above problems, the utility model proposes a precise negative pressure control device for an electric cupping device, which aims to reduce device noise, extend device life, and provide a more stable, adjustable and controllable negative pressure condition, providing an accurate, stable, adjustable and controllable negative pressure environment for the electric cupping device. Utility Model Content

[0007] In order to solve the above problems, the utility model proposes a negative pressure precise control device for an electric cupping device.

[0008] In order to solve the above problems, the technical solution of the present utility model is as follows:

[0009] The utility model discloses a negative pressure precise control device for an electric cupping device, which consists of a buffer gas tank, a negative pressure sensor, a control mainboard, an air pipe, an air pump, a micro pressure relief valve, a quick connector and the like.

[0010] Furthermore, the quick connector is a multi-air-path quick connector, one end of the micro pressure relief valve is connected to the quick connector, one end of the buffer gas tank is connected to the negative pressure sensor and the other end is connected to the quick connector, and the other two ends of the quick connector are respectively connected to the air pump and the cupping device.

[0011] Furthermore, one end of the micro pressure relief valve is connected to the quick connector and the other end is connected to the external environment, and the micro pressure relief valve is electrically connected to the control mainboard.

[0012] Furthermore, the negative pressure sensor is configured to compare the negative pressure value of the buffer gas tank with a set value to control the input power of the air pump and adjust the exhaust flow of the air pump; and prevent the negative pressure value from fluctuating significantly compared to the set value.

[0013] Furthermore, the buffer gas tank is connected to the quick connector and the negative pressure sensor respectively through an air pipe.

[0014] Furthermore, the electric cupping device uses a negative pressure precision control device connected to the cupping device through an air tube to control the pressure in the cupping device.

[0015] Furthermore, a PLC controller is provided in the control main board.

[0016] Furthermore, the control mainboard is provided with an MCU and a MOS tube.

[0017] Furthermore, when the electric cupping device is started, the air pressure value is set first, and then the air pump starts working to vacuum the system. The negative pressure sensor compares the negative pressure value of the system with the set value in real time, and controls the input power of the air pump and adjusts the exhaust flow of the air pump to prevent the negative pressure from fluctuating greatly at the set value position.

[0018] Furthermore, the device features a negative pressure adjustment function during use. If the negative pressure setting is changed during use and the negative pressure value falls below the current system negative pressure and exceeds the set deviation, the micro-pressure relief valve opens, increasing the system negative pressure until the system negative pressure reaches the set value, at which point the micro-pressure relief valve automatically closes. The buffer gas tank acts as a buffer in the system, improving the stability of negative pressure control.

[0019] Furthermore, the device has the function of programming and adjusting negative pressure, and can set a negative pressure change model in the time domain. The control system compares the negative pressure value in the system with the set value in real time based on the model, and controls the input power of the air pump or starts or closes the pressure relief valve accordingly, ultimately achieving continuous changes in negative pressure, that is, the fluctuating pressure and pulse pressure modes of the electric cupping device.

[0020] Furthermore, the device has a post-treatment release function. That is, after the treatment is completed, the cupping device is depressurized, and the negative pressure in the system does not drop to atmospheric pressure, but maintains a lower negative pressure, preferably 5-15kPa, so that the cupping device can be gently adsorbed on the human body and will not fall until the doctor removes it.

[0021] Compared with the prior art, the advantages and positive effects of the present invention are:

[0022] 1. The adoption of this new type of buffer gas tank can avoid frequent starting of the air pump and extend the service life of the air pump. The adoption of a micro pressure relief valve can accurately control the size of the negative pressure, stabilize the negative pressure state of the cupping device, and work together with the air pump to achieve programmed pressure control and pressure regulation functions.

[0023] 2. Through the precise negative pressure control device, the electric cupping device can achieve precise automatic control of negative pressure, and the negative pressure can be adjusted at any time during use; at the same time, it can realize functions such as wave cupping and pulse cupping; the air pump will be turned off when the negative pressure reaches the set value, reducing noise pollution; automatic pressure maintenance, small negative pressure fluctuation; it is extremely easy to use, only need to set the negative pressure value through the panel to automatically control it, without other operating steps.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification. Example 1

[0028] like Figure 1 As shown; a negative pressure precision control device for an electric cupping device, the device consists of a buffer gas tank 1, a negative pressure sensor 2, a control mainboard 3, an air pipe 4, an air pump 5, a micro pressure relief valve 6, and a quick connector 7.

[0029] The air inlet of the air pump 5 is connected to the quick connector 7, the micro pressure relief valve 6 is connected to the quick connector 7 through the air pipe, the buffer gas tank 1 is connected to the quick connector 7 and the negative pressure sensor 2 through the air pipe, and the air pipe 4 is connected to the quick connector 7.

[0030] The quick connector 7 is a multi-air-path quick connector, which is connected to the buffer gas tank 1, the air pipe 4, the micro pressure relief valve 6, and the air pump 5 through an air pipe.

[0031] The negative pressure precise control device for the electric cupping device is connected to the cupping device through the air pipe 4 to control the pressure in the cupping device.

[0032] The specific working process of this utility model:

[0033] The cupping device is connected to the negative pressure precise control device for the electric cupping device through the air inlet pipe 4. The user sets the pressure of the electric cupping device and starts the electric cupping device. When the electric cupping device is started, the air pump 5 starts to work to vacuum the system. The negative pressure sensor 2 compares the negative pressure value of the system with the negative pressure value set by the user in real time, controls the input power of the air pump 5, and adjusts the exhaust flow rate of the air pump 5 to prevent the negative pressure from fluctuating greatly at the set value position.

[0034] The device has the function of adjusting the negative pressure during use. If the negative pressure setting value is changed during use, the negative pressure value is lower than the current negative pressure of the system and exceeds the set deviation. At this time, the micro-pressure relief valve 6 opens and the system negative pressure increases until the system negative pressure reaches the set value, and the micro-pressure relief valve is automatically closed.

[0035] In order to avoid fluctuations in the negative pressure value and frequent starting of the air pump, the present invention is also equipped with a buffer gas tank 1. There is a set negative pressure in the buffer gas tank 1, and the negative pressure is consistent with the negative pressure value set by the user. When the pressure in the electric cupping device drops, the system does not have to start the air pump first, but instead uses the pressure in the buffer gas tank 1 for buffering, thereby playing a buffering role in the system and improving the stability of negative pressure control.

[0036] The control mainboard 3 used in the present invention uses an MCU and a MOS tube to control each actuator, and is electrically isolated by a photoelectric coupler in the middle, so that the input power of the air pump 5 can be adjusted, thereby accurately controlling the negative pressure and reducing noise.

[0037] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
