Description

Technical Field

[0001] The utility model relates to the field of slimming and beauty instruments, in particular to a negative pressure radio frequency beauty instrument. Background Art

[0002] The radio frequency beauty devices currently available on the market generally act on the treatment area through radio frequency electrodes, and then the electrodes emit radio frequency energy to destroy fat cells. Radio frequency energy can also damage the dermis, thereby promoting its active repair, which can play a role in tightening the skin after fat reduction. However, when the existing radio frequency electrodes act on the treatment area, they often cannot fit tightly with the skin, resulting in the inability to load a large amount of radio frequency energy into the treatment area, and unable to achieve a better effect. In this case, the market now mostly uses negative pressure suction to suck up the treatment area, and then the electrode can be attached to the treatment area over a large area to load radio frequency energy to achieve the effect. However, in this way, the stability of negative pressure becomes more important. During the current treatment process, the treatment area that was originally sucked up often relaxes after the pressure is lost due to loss of pressure, and the treatment effect is compromised.

[0003] Therefore, it is necessary to provide a negative pressure radio frequency beauty instrument to solve the above problems existing in the prior art. Utility Model Content

[0004] The purpose of the utility model is to provide a negative pressure radio frequency beauty instrument to solve the problem of unstable negative pressure in the handle, so that the negative pressure of the handle can be maintained within a threshold range, thereby improving the beauty effect.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows:

[0006] A negative pressure radio frequency beauty instrument, comprising:

[0007] handle;

[0008] A negative pressure suction mechanism is connected to the handle, and includes a negative pressure pump and a proportional valve. The proportional valve is arranged between the handle and the negative pressure pump. The negative pressure pump is used to generate negative pressure in the handle, and the proportional valve is used to control the threshold value of the negative pressure.

[0009] The beneficial effect of the negative pressure radio frequency beauty instrument provided by the utility model is that by arranging a proportional valve between the handle and the negative pressure pump, when air leakage occurs, the proportional valve can be adjusted according to the loss of air pressure, so that the negative pressure of the handle is maintained within the threshold range, and a large pressure loss will not occur, thereby ensuring that the skin of the beauty area remains attracted while the radio frequency is output, greatly improving the beauty effect.

[0010] Furthermore, the negative pressure suction mechanism also includes a gas tank, one end of which is connected to the proportional valve, and the other end is connected to the handle, for stabilizing the negative pressure. The beneficial effect is that the gas tank can absorb the gas pressure fluctuations during the operation of the negative pressure pump, thereby making the negative pressure environment of the handle stable, ensuring that the skin of the beauty area is stably attracted, and greatly improving the beauty effect.

[0011] Furthermore, the negative pressure suction mechanism also includes a sensor, and the sensor is used to monitor the negative pressure generated by the handle in real time.

[0012] Furthermore, it also includes a host, in which a main controller is arranged for controlling the start and stop of the negative pressure pump, the proportional valve and the sensor.

[0013] Furthermore, the host is connected to the handle via an electric cable and an air circuit.

[0014] Furthermore, a radio frequency signal generator is also provided in the host, and the radio frequency signal generator is connected to the main controller.

[0015] Furthermore, the proportional valve is an electromagnetic proportional valve, an electric proportional valve, or an electro-hydraulic proportional valve.

[0016] Furthermore, the handle comprises a working head and a hand-holding portion, and the hand-holding portion is connected to the working head.

[0017] Furthermore, the front end of the working head is open to form a cavity. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. Unless otherwise defined, the technical terms or scientific terms used herein should be understood by people with general skills in the field to which the utility model belongs. "Including" and similar words used in this article mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0023] The specific implementation of the utility model is further described in detail below in conjunction with the accompanying drawings.

[0024] like Figure 1-Figure 2 As shown, an embodiment of the utility model provides a negative pressure radio frequency beauty instrument, comprising: a handle 6 and a negative pressure suction mechanism. The negative pressure suction mechanism is connected to the handle 6. The negative pressure suction mechanism comprises a negative pressure pump 2 and a proportional valve 3. The proportional valve 3 is arranged between the handle 6 and the negative pressure pump 2. When the negative pressure pump 2 is started, the handle 6 connected to the negative pressure pump 2 generates negative pressure. The proportional valve 3 is used to control the threshold value of the negative pressure.

[0025] During the actual treatment process, the negative pressure presents periodic negative pressure attraction while the radio frequency is output. When the negative pressure reaches the preset threshold, the negative pressure is maintained and the radio frequency output is performed. However, in this process, since the contact surface between the skin of the area to be beautified and the negative pressure suction head (the working head of the handle) is not completely sealed, the negative pressure will drop significantly during the radio frequency output cycle. At the same time, the start and stop of the negative pressure pump 2 is delayed, and the negative pressure of the working head cannot be maintained within the threshold range by adjusting the speed or start and stop of the negative pressure pump 2. As a result, the skin cannot be effectively absorbed during the radio frequency output cycle, and the radio frequency energy cannot be fully loaded in the area to be beautified during the cycle, which affects the beauty effect and greatly reduces the beauty effect. Therefore, a proportional valve 3 is installed between the handle 6 and the negative pressure pump 2. The proportional valve 3 and the negative pressure pump 2 can cooperate to change the pumping speed and make up for the leaked air pressure, that is, the proportional valve 3 can adjust the opening of the proportional valve 3 according to the loss of air pressure, thereby maintaining a constant pressure in the handle 6. A proportional valve 3 is added to the negative pressure suction mechanism so that the negative pressure is maintained within the threshold range and a large pressure loss does not occur, thereby ensuring that the skin in the beauty area is always attracted while the radio frequency is output, which can greatly improve the beauty effect.

[0026] like Figure 1As shown, in some embodiments of the present invention, the proportional valve 3 is an electromagnetic proportional valve, an electric proportional valve, or an electro-hydraulic proportional valve. For example, the proportional valve 3 is an electromagnetic proportional valve, which controls the negative pressure threshold by adjusting the opening, has higher adjustment accuracy, faster response speed, and is easy to operate.

[0027] like Figure 1 As shown, in some embodiments of the utility model, the negative pressure suction mechanism further includes an air tank 5. One end of the air tank 5 is connected to the proportional valve 3, and the other end is connected to the handle 6, which is used to stabilize the negative pressure. That is, the negative pressure pump 2 is connected to the proportional valve 3, the proportional valve 3 is connected to the air tank 5, and the air tank 5 is connected to the handle 6. The air tank 5 can absorb the gas pressure fluctuation during the operation of the negative pressure pump 2, adjust the pressure in the gas circuit, so that the negative pressure is more stable, improve the effectiveness of the negative pressure, and can stably output the negative pressure within a certain range, ensuring that the skin is stably attracted.

[0028] Therefore, when the skin in the beauty area is actually attracted by negative pressure, it will not feel pain due to excessive pressure, nor will it affect the beauty effect due to too little or unstable pressure, thus ensuring that the skin is stably attracted, thereby improving the efficiency of beauty.

[0029] like Figure 1 As shown, in some embodiments of the present invention, the negative pressure suction mechanism further includes a sensor 4. The negative pressure sensor 4 is used to monitor the negative pressure generated by the handle 6 in real time. Therefore, it is possible to accurately know in real time whether the negative pressure is maintained within a reasonable range, and adjust the negative pressure by adjusting the proportional valve 3 or the gas tank 5 according to the negative pressure data transmitted by the sensor 4 until the negative pressure threshold is reached.

[0030] like Figure 1 As shown, in some embodiments of the present invention, the negative pressure radio frequency beauty instrument further comprises a host. A main controller 1 is arranged in the host for controlling the start and stop of the air pump 2, the proportional valve 3 and the sensor 4.

[0031] In some embodiments of the present invention, the host is connected to the handle 6 via a cable and an air circuit.

[0032] In some embodiments of the present invention, a radio frequency signal generator is also provided in the host, and the radio frequency signal generator is connected to the main controller 1, and the radio frequency signal generator performs radio frequency output.

[0033] In some embodiments of the utility model, a display screen is also provided on the host. The display screen is connected to the main controller 1. The host is operated on the display screen to control the handle 6.

[0034] like Figure 2As shown, in some embodiments of the present invention, the handle 6 includes a working head and a hand-held portion. The hand-held portion is connected to the working head. The working head is a component for contact beauty treatment of the skin. The hand-held portion is convenient for the operator to hold.

[0035] like Figure 2 As shown, in some embodiments of the present invention, the front end of the working head is opened to form a cavity 7. When the negative pressure pump 2 is started, a negative pressure environment is formed in the cavity 7 of the handle 6 to attract the skin of the beauty area and improve the effect of radio frequency treatment.

[0036] like Figure 3 As shown, when the host is started for beauty treatment, the main controller 1 starts the negative pressure pump 2 and the proportional valve 3, so that the negative pressure pump 2, the proportional valve 3 and the sensor 4 enter the working state. After the negative pressure pump 2 is started, the working head of the handle 6 is evacuated, and the negative pressure is judged whether the threshold is reached according to the pressure data measured in real time by the sensor 4, and the threshold range is 380-500mB. If it does not reach the threshold range, the negative pressure continues to increase to reach the preset negative pressure value for work. If it reaches the threshold range, the negative pressure pump 2 keeps running, and the air pressure fluctuation is adjusted by the proportional valve 3 to maintain the negative pressure in the working head stable within the threshold range. At the same time, the air tank 5 makes the air pressure output more steadily and constantly, so that the negative pressure environment in the cavity 7 in the working head is more stable. After the negative pressure in the cavity 7 of the working head is stable, the main controller 1 controls the radio frequency signal generator to output radio frequency energy for beauty treatment. After the end, stop the negative pressure pump 2 and control the proportional valve 3 to release the pressure.

[0037] After a certain period of time of treatment in a beauty treatment area, the treatment ends, the main controller 1 sends a signal to end the treatment, closes the negative pressure pump 2, the proportional valve 3, the sensor 4 and the working head of the handle 6, and waits for the next time the main controller 1 sends a signal again to start a new round of circulation.

[0038] In summary, the utility model designs a proportional valve in the negative pressure suction mechanism, and the proportional valve is adjusted according to the actual air pressure loss to ensure that the negative pressure of the handle is maintained within a threshold range, so that the skin of the beauty area is stably attracted; at the same time, the air storage tank is designed to make the air pressure fluctuation in the air circuit more stable and the output air pressure stable, which greatly improves the beauty effect compared with the existing technology.

[0039] Although the embodiments of the present invention are described in detail above, it is obvious to those skilled in the art that various modifications and variations can be made to these embodiments. However, it should be understood that such modifications and variations are within the scope and spirit of the present invention as described in the claims. Moreover, the present invention described herein may have other embodiments and may be implemented or realized in a variety of ways.
