Description

Technical Field

[0001] The utility model relates to the field of beauty instruments, in particular to a low-noise non-invasive water light instrument. Background Art

[0002] The water light instrument deeply moisturizes the skin by introducing the beauty liquid into the dermis of human skin, which can improve the skin's nutritional metabolism, make the skin smooth and translucent, and achieve the effect of anti-wrinkle and anti-aging. The existing water light instrument includes an air compressor, a molecular sieve and an operating handle. The air compressor pumps the air to the molecular sieve for filtering, and the filtered gas is sent to the operating handle, mixed with the beauty liquid in the operating handle, and then introduced into the dermis of the skin to perform water light beauty on the skin. Under normal circumstances, the internal air pressure of the air compressor is basically maintained at a normal level, which is far lower than the air pressure safety threshold (the normal value of the internal air pressure of the air compressor is generally only about 70% of the safety threshold, and a 30% margin is reserved), so the air compressor is generally not damaged due to excessive internal air pressure; however, if the operator does not use the operating handle to beautify the skin for a long time after turning on the water light instrument, it is easy to cause the internal air pressure of the air compressor to continue to rise until it exceeds the safety threshold, which will cause damage to the air compressor. For this reason, existing air compressors are equipped with a quick pressure relief valve, and the pressure relief trigger value of the quick pressure relief valve is slightly lower than the safety threshold (about 90% to 95% of the safety threshold). Once the internal air pressure of the air compressor exceeds the pressure relief trigger value of the quick pressure relief valve, the quick pressure relief valve opens to allow the air compressor to exhaust quickly to achieve pressure relief. In order to prevent the internal air pressure of the air compressor from exceeding the safety threshold, the existing quick pressure relief valve needs to discharge a large amount of gas in a short period of time after opening, so that the internal air pressure of the air compressor drops to a normal value in a relatively short period of time. Therefore, the existing quick pressure relief valve has a large pressure relief flow (i.e., the maximum exhaust volume in the same time). The greater the exhaust volume per unit time, the exponentially greater the noise generated. The air compressor of the existing water light instrument generates a large noise due to the rapid exhaust. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a non-invasive water light instrument, which can improve the noise problem.

[0004] In order to solve the above problems, the utility model provides a low-noise non-invasive hyaluronic acid analyzer: it comprises an air compressor, a molecular sieve and an operating handle which are connected together in sequence, the air is supplied from the air compressor to the molecular sieve for filtration and then to the operating handle; the air compressor is equipped with a quick pressure relief valve, when the actual internal air pressure of the air compressor is higher than the pressure relief trigger value of the quick pressure relief valve, the quick pressure relief valve opens to allow the air compressor to exhaust quickly until the internal air pressure of the air compressor drops to a normal value; an auxiliary pressure relief device is connected between the air compressor and the molecular sieve, the pressure relief trigger value of the auxiliary pressure relief device is lower than the quick pressure relief valve, and can be opened before the quick pressure relief valve to exhaust the air from the air compressor first.

[0005] Furthermore, the pressure relief trigger value of the auxiliary pressure relief device is higher than the normal value of the internal air pressure of the air compressor.

[0006] Furthermore, the pressure relief flow rate of the auxiliary pressure relief device is smaller than that of the quick pressure relief valve.

[0007] Furthermore, a three-way joint is provided between the air compressor and the molecular sieve, wherein two ends of the three-way joint are respectively connected to the air compressor and the molecular sieve, and the remaining end is connected to the auxiliary pressure relief device.

[0008] Furthermore, a radiator and a regulating valve are connected between the air compressor and the three-way joint.

[0009] Furthermore, it comprises a base, and the air compressor, the auxiliary pressure relief device, the three-way joint, the radiator and the regulating valve are all installed inside the base.

[0010] Furthermore, it comprises a support frame, the molecular sieve is installed in the support frame, the input end of the molecular sieve is located at the lower part of the support frame, and the three-way joint is connected to the input end of the molecular sieve through a gas pipe.

[0011] Furthermore, the auxiliary pressure relief device comprises a mechanical pressure relief valve connected between the air compressor and the molecular sieve, and the output end of the mechanical pressure relief valve is connected to a muffler.

[0012] Beneficial effects: The auxiliary pressure relief device can be opened before the quick pressure relief valve to exhaust the air compressor. Therefore, when the auxiliary pressure relief device is opened, the internal air pressure of the air compressor is not higher than the pressure relief trigger value of the quick pressure relief valve, and is not higher than the safety threshold, so it will not cause damage to the air compressor. The auxiliary pressure relief device does not need to make the air compressor exhaust a large amount of gas in a short time like the quick pressure relief valve, but can make the air compressor continue to exhaust slowly, the exhaust volume per unit time is small, and the noise generated by exhaust is also small. In the process of the auxiliary pressure relief device remaining open and the air compressor slowly exhausting, if the actual internal air pressure of the air compressor continues to rise to a level higher than the pressure relief trigger value of the quick pressure relief valve, the quick pressure relief valve will open and make the air compressor exhaust quickly, so that the internal air pressure of the air compressor will quickly drop to a normal value. Although the noise generated by triggering the quick exhaust is still as loud as that of the prior art, the air compressor has already exhausted air through the auxiliary pressure relief device before the quick pressure relief valve is triggered to open. Therefore, compared with the prior art, the internal air pressure of the air compressor of the non-invasive hyaluronic acid analyzer of the present invention is less likely to be higher than the pressure relief trigger value of the quick pressure relief valve under the same usage scenario. The air compressor of the present invention triggers quick exhaust less frequently and the overall noise is also less. In addition, when the quick pressure relief valve is triggered to open, the auxiliary pressure relief device is still in the open state, that is, the air compressor at this time exhausts air through both the quick pressure relief valve and the auxiliary pressure relief device, that is, under the premise that the total exhaust volume of the air compressor remains unchanged and the quick pressure relief valve exhausts air at its own maximum pressure relief flow rate, the quick pressure relief valve exhausts air in a shorter time and the noise duration is shorter; or, under the premise that the total exhaust volume of the air compressor remains unchanged and the exhaust time of the quick pressure relief valve remains unchanged, the actual pressure relief flow of the quick pressure relief valve is less than its own maximum pressure relief flow rate, and the noise generated is less.

DETAILED DESCRIPTION

[0021] The present invention is further described in detail below in conjunction with specific implementation methods.

[0022] See Figure 1 The non-invasive water light instrument 1 includes a base 11, a support frame 12 and an operating table 13. The base 11 shell and the support frame 12 shell are hidden. Figure 2 and Figure 4 The base 11 is equipped with an air compressor 2, the support frame 12 is equipped with a molecular sieve 3, and the operating table 13 is provided with an operating handle (not shown in the figure). The air compressor 2, the molecular sieve 3 and the operating handle are connected in sequence. The air is sent from the air compressor 2 to the molecular sieve 3 for filtration, and then sent to the operating handle after being filtered by the molecular sieve 3. After being mixed with the beauty liquid in the operating handle, the air is sent to the skin by the operating handle for water light beauty. The molecular sieve 3 and the operating handle are conventional technologies, and their working principles and specific structures are not described here.

[0023] See inside the base 11 Figure 3 and Figure 5 , equipped with a radiator 41, an electromagnetic regulating valve 42, a three-way joint 5, a mechanical pressure relief valve 61 and multiple sections of gas pipes 71, 72, 73. The output end 21 of the air compressor 2 is connected to the first section of the gas pipe 71, which passes through the radiator 41 and the electromagnetic regulating valve 42 in sequence and then connects to the first end 51 of the three-way joint 5; the second end 52 of the three-way joint 5 is connected to the input end 31 of the molecular sieve 3 located at the lower part of the support frame 12 through the second section of the gas pipe 72, and the air compressor 2 is connected to the molecular sieve 3 through the first section of the gas pipe 71, the three-way joint 5 and the second section of the gas pipe 72. Figure 6 The third end 53 of the three-way connector 5 is connected to the input end of the mechanical pressure relief valve 61 through the third section of the gas pipe 73. The mechanical pressure relief valve 61 is thus connected between the air compressor 2 and the molecular sieve 3, and is connected to the air compressor 2 through the third section of the gas pipe 73, the three-way connector 5 and the first section of the gas pipe 71.

[0024] When the operator starts the non-invasive water light instrument 1 to perform water light beauty treatment on the skin, the internal air pressure of the air compressor 2 will continue to rise, and the air compressor 2 generally exhausts and releases pressure through the mechanical pressure relief valve 61; the air compressor 2 is connected to a conventional quick pressure relief valve (not shown in the figure), and when necessary, exhausts and releases pressure through the quick pressure relief valve to prevent the air compressor 2 from being damaged due to the internal air pressure exceeding the safety threshold. The pressure relief trigger value of the quick pressure relief valve is higher than the normal value of the internal air pressure of the air compressor 2 (i.e., the value of the internal air pressure of the air compressor 2 when it is operating normally) but lower than the safety threshold of the air compressor 2, and its pressure relief flow (i.e., the maximum exhaust volume in the same time) is relatively large; while the pressure relief trigger value of the mechanical pressure relief valve 61 is higher than the normal value of the internal air pressure of the air compressor 2 but lower than the pressure relief trigger value of the quick pressure relief valve, and its pressure relief flow is smaller than that of the quick pressure relief valve. When the actual internal air pressure of the air compressor 2 continues to rise to a value higher than the pressure relief trigger value of the mechanical pressure relief valve 61, the mechanical pressure relief valve 61 opens before the quick pressure relief valve, thereby first exhausting the air compressor 2. Since the internal air pressure of the air compressor 2 is not higher than the pressure relief trigger value of the quick pressure relief valve, let alone the safety threshold, it will not cause damage to the air compressor 2. The mechanical pressure relief valve 61 with a smaller pressure relief flow rate can allow the air compressor 2 to continue to exhaust slowly, with a smaller exhaust volume in the same time, and the noise generated by exhaust is also smaller. Figure 6 The output end of the mechanical pressure relief valve 61 is equipped with a muffler 62, which can further reduce the noise generated by the exhaust gas. The mechanical pressure relief valve 61 and the muffler 62 together constitute an auxiliary pressure relief device. Preferably, the pressure relief trigger value of the mechanical pressure relief valve 61 can be changed to be equal to the normal value of the internal air pressure of the air compressor 2.

[0025] In the process of mechanical pressure relief valve 61 being kept open and air compressor 2 being exhausted slowly, if the actual internal air pressure of air compressor 2 continues to rise to a value higher than the pressure relief trigger value of quick pressure relief valve, the quick pressure relief valve with a larger pressure relief flow rate is triggered to open and the air compressor 2 is exhausted quickly, so that the internal air pressure of air compressor 2 drops rapidly to a normal value. Not preferably, the quick pressure relief valve can be changed to allow the air compressor 2 to be exhausted quickly so that its internal air pressure drops rapidly to a value lower than the pressure relief trigger value of the quick pressure relief valve, but this will cause the quick pressure relief valve to be frequently triggered to open. A large noise will be generated during the rapid exhaust process, but before the quick pressure relief valve is triggered to open, the air compressor 2 has already been exhausted through the mechanical pressure relief valve 61. Therefore, in the same use scenario, the internal air pressure of air compressor 2 is less likely to be higher than the pressure relief trigger value of the quick pressure relief valve, the number of times the quick exhaust is triggered is less, and the noise generated during the entire beauty process is also less. In addition, when the quick pressure relief valve is triggered to open, the mechanical pressure relief valve 61 is still in an open state, that is, the air compressor 2 is exhausted through both the quick pressure relief valve and the mechanical pressure relief valve 61. In this way, under the premise that the total exhaust volume of the air compressor 2 remains unchanged and the quick pressure relief valve exhausts at its own maximum pressure relief flow rate, the quick pressure relief valve takes a shorter time to exhaust, that is, the noise lasts for a shorter time; or, under the premise that the total exhaust volume of the air compressor 2 remains unchanged and the quick pressure relief valve takes a longer time to exhaust, the actual pressure relief flow rate of the quick pressure relief valve is less than its own maximum pressure relief flow rate, that is, the noise generated is smaller.

[0026] The above is only an implementation method of the invention, and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the invention, which still fall within the scope of patent protection.
