Description

Technical Field

[0001] The invention relates to the technical field of cooling devices, in particular to a rapid skin cooling device. Background Art

[0002] An epidermal cooling device is a medical device used to apply cold compresses to specific parts to relieve pain, reduce inflammation or lower local temperature. It usually provides effective cold therapy by controlling the temperature and application time. It is often used to relieve symptoms such as trauma, sprains, swelling, etc., as well as assist in laser treatment of skin diseases. In particular, in the operation of assisting laser treatment of skin diseases, since laser irradiation on the skin will quickly generate heat, the cooling system of the epidermal cooling device is required to quickly cool and generate cold air to perform jet cooling on the laser irradiation part to ensure that the temperature of the skin surface is effectively controlled and cooled during laser treatment, thereby reducing the damage or discomfort to the skin caused by laser treatment.

[0003] The vortex tube is a device that uses the vortex effect to cool. It consists of a sealed metal tube filled with an inert gas (usually helium or nitrogen) and an alternating current applied through a power supply. When the current passes through the metal tube, an alternating magnetic field is generated, causing the high-speed airflow in the tube to generate a vortex to separate the cold and hot airflows, and the cold airflow is used to obtain a cooling method. Since the vortex tube can provide fast and efficient cooling, the use of vortex tubes as cooling is widely used in epidermal cooling devices.

[0004] Existing epidermal cooling devices usually blow cold air continuously when in operation. Although they can quickly cool down the epidermis to be treated by laser, the continuous blowing of cold air will reduce the temperature of blood vessels under the epidermis, which is not conducive to laser thermal therapy. If the epidermal cooling device starts and stops by cyclically controlling the cooling system, the side effects caused by overcooling can be avoided, and the cyclic control can also reduce the overall energy consumption, but the frequent start and stop will increase the starting power of the cooling system, thereby affecting the overall energy efficiency. Moreover, the repeated start and stop of the vortex tube will increase the fluctuation of the cooling temperature. Such temperature fluctuation will make the cooling process of the epidermal cooling device unstable, which may easily lead to inconsistent skin reactions, thereby affecting the effect of laser treatment. Especially in the treatment process that requires precise temperature control, the temperature fluctuation will have a negative impact on the treatment results.

[0005] In view of this, in order to overcome the above technical problems, the present invention proposes a skin rapid cooling device to solve the above technical problems. Summary of the invention

[0037] The transmission gear 22 is arranged as a multi-stage gear; the output shaft of the driving motor 23 is provided with a groove 231; the gear shaft 221 is slidingly and sealingly connected in the groove 231; a fixing spring 232 is arranged in the groove 231; one end of the fixing spring 232 is fixedly connected to the bottom of the groove 231; the other end is fixedly connected to the gear shaft 221; a pushing unit is installed in the chassis 1; the pushing unit is used to push the gear shaft 221 to slide in the groove 231.

[0038] The pushing unit includes an electromagnetic sheet 24 ; the electromagnetic sheet 24 is embedded in the bottom of the groove 231 .

[0039] An annular groove 26 is provided on the surface of the baffle 21; the arc groove 211 is provided at the bottom of the annular groove 26; a straight cylinder 261 fixedly connected to the rotating drum 2 is rotatably connected in the annular groove 26; the straight cylinder 261 is connected to the through groove 28; an air cavity 262 connected to the arc groove 211 is provided inside the baffle 21; an air pipe 263 connected to the air cavity 262 is provided on one side of the baffle 21; the end of the air pipe 263 away from the air cavity 262 faces the high-pressure air pump 11; a closing unit is installed in the air cavity 262.

[0040] The closing unit includes a closing plate 264; the closing plate 264 is slidably and sealingly connected in the air cavity 262; the closing plate 264 is fixedly connected to the cavity wall of the air cavity 262 via a supporting spring 265; the lower end surface of the closing plate 264 is provided with an L-shaped groove 266 communicating with the air cavity 262;

[0041] When the epidermal cooler is in operation, it usually blows cold air continuously. Although it can quickly cool down the epidermis to be treated by laser, the continuous blowing of cold air will reduce the temperature of blood vessels under the epidermis, which is not conducive to laser thermal therapy. If the epidermal cooler starts and stops by cyclically controlling the cooling system, the side effects caused by excessive cooling can be avoided, and the cyclic control can also reduce the overall energy consumption, but the frequent start and stop will increase the starting power of the cooling system, thereby affecting the overall energy efficiency. Moreover, the repeated start and stop of the vortex tube 12 will increase the fluctuation of the cooling temperature. Such temperature fluctuation will make the cooling process of the epidermal cooler unstable, which may easily lead to inconsistent skin reactions, thereby affecting the effect of laser treatment. Especially in the treatment process that requires precise temperature control, temperature fluctuation will have a negative impact on the treatment results.

[0042] During operation, the user controls the high-pressure air pump 11 to deliver high-pressure air to the vortex chamber 121 of the vortex tube 12, so that the high-pressure air in the vortex chamber 121 generates a vortex to separate cold and hot air flows, wherein the hot air in the outer circle is discharged through the heat exhaust port 123. Since the heat exhaust port 123 is close to the air diffusion holes 15 of the chassis 1, the hot air discharged from the heat exhaust port 123 can be discharged through the air diffusion holes 15; and the cold air flow in the inner circle is blocked by the blocker in the heat exhaust port 123, so that it is discharged from the refrigeration port 122 in the reverse direction, and the cold air flow discharged from the refrigeration port 122 enters the arc groove 211 of the baffle 21 connected thereto; and a temperature detector is installed in the refrigeration port 122 of the vortex tube 12, and the temperature detector is used to monitor in real time The temperature in the refrigeration port 122 is measured; and the gas pressure delivered to the vortex tube 12 by the high-pressure air pump 11 is controlled to adjust the temperature of the cold air ejected from the refrigeration port 122 of the vortex tube 12, so that the user can adjust and use it according to needs; because in the initial state, the through groove 28 on the surface of the rotating drum 2 is connected with the arc groove 211, so the cold air ejected from the refrigeration port 122 into the arc groove 211 will flow into the rotating drum 2 through the through groove 28 connected with the arc groove 211, and will be ejected by the exhaust pipe 131 and the nozzle 14. The user only needs to hold the nozzle 14 and aim it at the skin where the user needs to cool quickly, so that the discharged cold air can cool the skin; although the continuous blowing of cold air can quickly treat the laser The epidermis is cooled down, but continuous blowing of cold air will reduce the temperature of blood vessels under the epidermis, which is not conducive to laser thermal therapy; at this time, the user needs to control the operation of the driving motor 23 so that the driving motor 23 can drive the gear shaft 221 connected to its output end to rotate, so that the gear shaft 221 can drive the transmission gear 22 meshing with it to rotate during the rotation; because the transmission gear 22 is fixed to the outer wall of the rotating drum 2, the transmission gear 22 driven by the gear shaft 221 can drive the rotating drum 2 to rotate, so that the rotating drum 2 rotates relative to the baffle 21, and the rotating rotating drum 2 drives the through groove 28 opened on the surface to rotate synchronously; so that the rotating drum 2 drives the through groove 28 on the surface to rotate and cross the arc groove 21 1, at this time, the through groove 28 and the arc groove 211 are no longer connected, so that the cold air flowing from the vortex tube 12 to the arc groove 211 will not flow to the exhaust pipe 131 and the nozzle 14 through the through groove 28, that is, the nozzle 14 stops spraying cold air at this time, until the drum 2 drives the through groove 28 to rotate again at the arc groove 211, so that when the through groove 28 and the arc groove 211 are connected, the cold air sprayed from the vortex tube 12 can be sprayed through the nozzle 14, thereby realizing intermittent blowing of cold air, and there is no need to repeatedly start and stop the vortex tube 12, which not only avoids the increase of fluctuation of the refrigeration temperature and reduces the influence of temperature fluctuation on the treatment result, but also avoids the increase of the starting power of the cooling system caused by frequent start and stop, thereby improving the overall energy efficiency;

[0043] When the drum 2 drives the through groove 28 to rotate until it is not connected with the arc groove 211, the cold air generated by the vortex tube 12 cannot be discharged through the arc groove 211, so that the cold air flow will accumulate in the arc groove 211, and the cold air pressure in the arc groove 211 will increase. When the drum 2 drives the through groove 28 to be connected with the arc groove 211 again, the cold air accumulated in the arc groove 211 will quickly enter the through groove 28 and be discharged from the exhaust pipe 131 and the nozzle 14; at this time, the impact force of the cold air ejected by the nozzle 14 is relatively large, thereby increasing the injection speed and intensity of the cold air; and during the laser treatment process, the excessive impact of the cold air will rapidly reduce the temperature of the skin surface, which will exceed the safety range required for treatment and cause excessive cooling; in this regard, the closing plate 26 is set 4 and the straight cylinder 261, because in the initial state, the straight cylinder 261 is fixedly connected in the through groove 28, and the rotating cylinder 2 drives the straight cylinder 261 to rotate and connect in the annular groove 26, and the closing plate 264 located in the annular groove 26 is located at the notch of the arc groove 211, at this time, the end of the L-shaped groove 266 of the closing plate 264 away from the air cavity 262 faces the arc groove 211, when the rotating cylinder 2 drives the through groove 28 to rotate to the arc groove 211, the straight cylinder 261 in the through groove 28 will contact the closing plate 264, so that the straight cylinder 261 pushes the closing plate 264 to squeeze the supporting spring 265 into the air cavity 262, so that the closing plate 264 drives the L-shaped groove 266 to enter the air cavity 262, and at this time, the end of the air cavity 262 close to the arc groove 211 is opposite to the air cavity 262. The L-shaped groove 266 is blocked, so that the straight tube 261 faces the arc groove 211, so that the cold air discharged from the arc groove 211 only flows from the straight tube 261 into the through groove 28, and finally is ejected through the nozzle 14; when the straight tube 261 passes over the arc groove 211, the straight tube 261 no longer blocks the closing plate 264, so that the closing plate 264 extends out of the air cavity 262 under the push of the restoring force of the supporting spring 265. At this time, the closing plate 264 drives the end of the L-shaped groove 266 away from the air cavity 262 to extend out of the air cavity 262 and toward the arc groove 211, so that the cold air in the arc groove 211 flows into the air cavity 262 through the L-shaped groove 266, and flows into the air pipe 263 from the air cavity 262. Since the air pipe 263 is connected to the outside, the cold air flowing into the air pipe 263 can can be effectively discharged; and because the hot air discharged from the heat exhaust port 123 will gather around the heat dissipation holes of the chassis 1, the heat of the air around the chassis 1 will increase, and the high-pressure air pump 11 will inhale the hot air around the chassis 1 and transport it to the vortex tube 12, which will reduce the cooling effect of the vortex tube 12, so the air pipe 263 is arranged away from the end of the air cavity 262 toward the high-pressure air pump 11, so that the cold air flow can not only blow away the hot air around the high-pressure air pump 11, but also reduce the air around the high-pressure air pump 11, so as to reduce the hot air inhaled by the high-pressure air pump 11, so as to ensure the temperature of the cold air generated by the vortex tube 12 is stable, thereby ensuring that the epidermal cooling device can stably perform treatment, thereby reducing the negative impact of temperature fluctuations on the treatment results;

[0044] Since the skin of different patients has different sensitivity and reaction ability to heat; some patients' skin is more sensitive and has a lower tolerance to heat, and needs more frequent cooling to avoid overheating; while other patients' skin is relatively heat-resistant and can maintain normal treatment temperature for a longer time without frequent cooling; therefore, adjusting the interval time for the epidermal refrigerator to blow out cold air is crucial to optimizing skin protection and effect during treatment; although the speed of the motor can be changed by installing a speed regulating motor to adjust the rotation speed of the gear shaft 221, thereby changing the rotation speed of the straight cylinder 261 in the annular groove 26, and changing the connection time between the straight cylinder 261 and the arc groove 211, the manufacturing cost of the speed regulating motor is relatively high, which increases the overall production cost of the present invention, and for this purpose, the transmission gear 22 is set as a multi-stage gear; the multi-stage gear is provided with at least three stages (the first stage is close to the center, and the third stage is far from the center), and the modulus ratio of the multi-stage gear is 1:2:3 from inside to outside. In the initial state, the gear shaft 221 is located at the first stage of the multi-stage gear. When the rotation speed of the drum 2 needs to be reduced, the electromagnetic sheet 24 is energized so that the gear shaft 221 squeezes the fixed spring 232 into the groove 231 under the action of the magnetic adsorption force of the electromagnetic sheet 24. At this time, the meshing teeth of the gear shaft 221 move downward under the drive of the gear shaft 221, so that the meshing teeth of the gear shaft 221 mesh with the second stage teeth of the multi-stage gear; and by setting the upper and lower ends of the meshing teeth of the gear shaft 221 and the upper and lower ends of the teeth of each level of the transmission gear 22 to be curved, so that in the process of the gear shaft 221 driving the meshing teeth on the surface to move up and down, the meshing teeth of the gear shaft 221 push the curved ends of the teeth of each level of the multi-stage gear through the curved end, avoiding the teeth of each level of the transmission gear 22 blocking the meshing teeth of the gear shaft 221 from sliding up and down, thereby ensuring that the gear shaft 221 can be quickly replaced between the various levels of the transmission gear 22, thereby improving the practicality of the present invention;

[0045] The present invention cooperates with the gear shaft 221 and the transmission gear 22 so that the driving motor 23 drives the transmission gear 22 to rotate through the gear shaft 221, so that the transmission gear 22 drives the rotating drum 2 to rotate, and when the rotating drum 2 drives the through groove 28 to rotate and cooperates with the arc groove 211 of the baffle 21, the cold air in the vortex tube 12 can enter the nozzle 14 through the rotating drum 2 and be sprayed out by the nozzle 14, thereby eliminating the need to repeatedly start and stop the vortex tube 12, which not only avoids the increase in fluctuations in the refrigeration temperature and reduces the impact of temperature fluctuations on the treatment results, but also avoids the increase in the starting power of the cooling system caused by frequent starts and stops, thereby improving the overall energy efficiency.

[0046] In this embodiment, a spiral groove 27 is opened inside the baffle 21; two return pipes 271 are connected to both ends of the spiral groove 27; one of the return pipes 271 is connected to the heat dissipation port 123; and the other return pipe 271 faces the heat dissipation hole.

[0047] The chassis 1 is provided with an air storage tank 16; an air inlet 161 and an air outlet 162 are provided at the upper end of the air storage tank 16; solenoid valves 163 are installed in the air inlet 161, the air outlet 162 and the air pipe 263; the air inlet 161 is connected to a return pipe 271 away from the heat exhaust port 123; the air outlet 162 is communicated with the air cavity 262;

[0048] During operation, in southern weather, the air often contains more moisture, so when the high-pressure air pump 11 delivers air to the vortex tube 12, the air in the water inlet vortex tube 12 will carry moisture and flow out from the refrigeration port 122 and the heat exhaust port 123, so that the cold air discharged from the refrigeration port 122 carries moisture and enters the drum 2 through the arc groove 211 and the straight cylinder 261; since the drum 2 and the baffle 21 are made of metal material, this is because the drum 2 and the baffle 21 made of metal material can maintain a stable structure and will not be deformed by the high-pressure airflow; however, when the cold air flows through the drum 2 and the baffle 21, the temperature of the drum 2 and the baffle 21 will decrease, thereby causing the temperature at the outer wall of the drum 2 and the baffle 21 to To the dew point temperature, the moisture in the outside air will condense on the surface of the drum 2 and the baffle 21. The surface temperatures of the drum 2 and the baffle 21 are relatively low, which will cause the moisture condensed on the surface of the drum 2 to freeze, thereby causing adhesion between the drum 2 and the baffle 21 due to the frozen moisture, thereby hindering the driving effect of the drive motor 23 on the drum 2; for this, a spiral groove 27 is opened inside the baffle 21; the spiral groove 27 is connected to the heat exhaust port 123 and the air storage tank 16 through the return pipe 271; the hot air flow discharged from the heat exhaust port 123 of the vortex tube 12 can flow into the spiral groove 27 through the return pipe 271 connected thereto, so that the hot air flow flowing into the spiral groove 27 heats the outer wall of the baffle 21, This prevents the condensed water between the baffle 21 and the drum 2 from freezing, prevents the drum 2 and the baffle 21 from sticking, and ensures the rotation speed of the drum 2; thereby reducing the obstruction to the drive motor 23 and improving the driving effect of the drive motor 23; and the arrangement of the air storage tank 16 allows the hot air discharged from the heat exhaust port 123 to pass through the spiral groove 27 and the return pipe 271 connected to the air storage tank 16 to the air storage tank 16, so that the hot air flow is stored in the air storage tank 16, so that the hot air flow will not be dispersed into the air around the chassis 1, reducing the temperature of the air around the chassis 1, thereby reducing the temperature of the air inhaled by the high-pressure air pump 11, ensuring the stability of the temperature of the air flow discharged from the vortex tube 12, and reducing temperature fluctuations. It will have a negative impact on the treatment results; although the heat exhaust port 123 will not exhaust the hot air to the surrounding of the chassis 1, when the hot air is discharged through the exhaust port 13, the hot air will spread the heat to the surrounding air in the form of thermal radiation. For this, the air pipe 263 facing the high-pressure air pump 11 can still cool the air around the high-pressure air pump 11 by intermittently spraying cold air, thereby ensuring the use effect of the air pipe 263, so that the practicality of the present invention is improved; after the vortex tube 12 is used for a long time, frost will condense in the refrigeration port 122 of the vortex tube 12, and it is often necessary to stop the epidermal cooler and heat and defrost the frost in the refrigeration port 122 of the vortex tube 12 by controlling the defrosting device;The addition of defrosting equipment will increase the production cost of the epidermal cooler, and controlling the defrosting equipment to heat the frost in the refrigeration port 122 of the vortex tube 12 will increase the consumption of electric energy. For this purpose, an electromagnetic valve 163 is provided in the air outlet 162 and the air inlet 161 of the air storage tank 16, and the electromagnetic valve 163 in the air inlet 161 is controlled to be opened, so that the air storage tank 16 collects the hot air flow discharged from the heat exhaust port 123 of the vortex tube 12; and the electromagnetic valve 163 of the air outlet 162 is opened, so that when it is necessary to defrost the refrigeration port 122 of the vortex tube 12, the vortex The hot air stored in the tube 12 is transported to the air cavity 262 through the pipeline. At this time, the solenoid valve 163 in the air pipe 263 is in a closed state, thereby preventing the hot air from being ejected from the air pipe 263 and accumulating in the chassis 1; so that when the hot air entering the air cavity 262 flows through the refrigeration port 122 of the vortex tube 12, the hot air can defrost the refrigeration port 122 of the vortex tube 12, thereby reducing the manufacturing cost of the present invention, reducing the consumption of electric energy, and improving the use cost of the present invention, so that the practicality of the present invention is further improved. ;
