With the rapid development of economy, the demand of people for beauty is gradually increased, so that the beauty and medical industry is generated. The birth of the novel optical fiber is in the 90 s of the 20 th century, and is based on expansion in the fields of medicine, optics, electricity, chemistry and the like. With the addition of various professionals, more and more high-tech instruments enter the beauty treatment and medical industry, and the beauty treatment instruments are also subjected to another update. The volume of the instrument is changed from huge instruments to medium-sized, medium-sized and small-sized instruments, so that the small-sized and micro-sized instruments become a trend nowadays, and the beauty instrument gradually goes into thousands of households from hospitals and beauty parlors. The functions of the hair remover are gradually developed from single depilation, whitening and the like to one machine with multiple functions, the development of science and technology is gradually perfected, and the application of the hair remover to a cosmetic instrument enables the functions of the hair remover to be more diversified and finer. The skin treatment equipment provided by the application can provide rich combined functions of micro-current, radio frequency, cold and hot compress and the like. The micro-current is a minute current as the name implies, and the micro-current is a minute current such as a minute current and a microampere, which is smaller than an ampere, and the micro-ampere and the current hereafter are called a micro-current.

However, when the skin cells are subjected to skin care effect under the stimulation of micro-current and radio frequency, the skin cells inevitably cause some pain to the user of the skin treatment equipment, and cause redness and swelling of the skin of the user to different degrees. In order to cope with this problem, the conventional skin treatment apparatuses are often equipped with a cold compress function for cold compress the skin portion simultaneously or after achieving functions such as micro-current and radio frequency, so as to achieve the effects of temporarily calming skin cells, alleviating pain, and alleviating redness and swelling. Cold compress is also only temporary in relief of symptoms and is not universal, and long-term cold compress is also awkward to cause skin frostbite. Even if the emergency treatment is performed by using the cold compress function, the long detumescence and recovery process still needs to be born by the body of the user.

Even without stimulation by microcurrents, radio frequencies, etc., problems such as dryness, oedema, redness, etc. may occur in the skin area with body metabolism, season changes, and changes in hormone levels. The skin treatment device has the advantages that the skin treatment device is convenient to use, the temperature of the skin treatment device is low in winter, the cold compress piece is enabled to be stimulated by cold when contacting the skin, and the skin treatment device is not suitable for the user, and the cosmetic effect is affected.

How to finish a series of skin repair and care processes from cold compress and tranquillize skin, inhibiting pain and swelling, comfort skin treatment, hot compress and quicken blood circulation, promote metabolism and detumescence and the like on the premise of carrying out microcurrent, radio frequency and other treatments on the skin, and simultaneously promote skin touch, thereby improving the beautifying effect.

Through setting up cold compress 1, reduce the heat that electrode 6 produced to the skin stimulation, cool down to the skin epidermis, play cold compress calm effect, avoid the too high skin of burn of temperature, reduce the uncomfortable sense in the use, improve the use comfort of operating head. The first refrigerating piece 2 refrigerates the cold compress piece 1 in the cold compress mode, so that the cold compress piece 1 can continuously cool the skin epidermis, stimulate subcutaneous capillary contraction, relieve redness, swelling and pain, and tighten the skin to realize the beauty effect. Switching to the hot compress mode, the second refrigerating member 51 heats the cold compress member 1, so that the cold compress member 1 continuously applies hot compress to the epidermis of the skin, expands subcutaneous capillaries, accelerates local blood circulation, promotes metabolism to reduce swelling, helps the skin barrier to recover health, and stimulates cell regeneration to realize a cosmetic effect.

The alternating process of cold and hot can also expand and contract the skin, strengthen the respiration of the skin, better stimulate the collagen tightening and regeneration of the dermis layer, tighten the skin and improve the beauty effect while protecting the skin from being damaged.

Alternatively, the skin site may be facial skin, the shallower skin site may be epidermis, and the deeper skin site may be dermis. The electrode 6 is discharged when in operation, and can generate radio frequency, micro-current and the like to beautify the facial skin.

Alternatively, the electrode 6 may be fixedly mounted on the first cover 4. The skin treatment device may be applied in a cosmetic instrument.

The first refrigerating element 2 and the second refrigerating element 51 are not ejected out of the second opening 24 and are blocked at the edge of the second opening 24 due to deformation caused by the collision. Thus, the skin treatment device has a better durability in daily use.

Alternatively, the conduction surface 1b of the cold compress may be in direct surface contact with the cooling surface of the first cooling element 2 and the heating surface of the second cooling element 51. The surface contact mode has more sufficient heat conduction and can maximize the conduction effect.

A cold conducting layer 7 can be arranged between the second refrigerating piece 51 and the cold compress piece 1 and/or the heat dissipation piece 3, so that the effect of the hot compress function of the cold compress piece 1 can be improved, and the heat dissipation piece 3 can dissipate heat of other components of the skin treatment device by utilizing the refrigerating effect of the second refrigerating piece 51.

Since the first and second refrigerating elements 2 and 51 are generally operated in a time-sharing manner, in order to avoid the influence of the residual temperature after one operation or the temperature during the operation on the other, a heat insulating material is disposed between the first and second refrigerating elements 2 and 51 to weaken the heat transfer between the first and second refrigerating elements 2 and 51.

Alternatively, since the first cooling element 2 needs to lower the temperature of the cold pack 1 to a temperature at which effective cold pack cosmetic treatment can be achieved on the skin site, for example, 19 to 20 ℃, the cold pack effect of contracting capillary vessels on the skin site, relieving redness and swelling, and alleviating pain can be achieved. In order to avoid damage to the skin site, the second cooling member 51 is operated to raise the temperature of the cold compress member 1 up to 42 ℃ to expand the capillary vessel of the skin site and promote blood circulation, thereby accelerating cell repair and skin detumescence.

Referring to fig. 5, in the present embodiment, the second panel portion 49 of the second cover 8 is made of a heat-conducting material, so the second panel portion 49 may not be provided with the second opening 24, but is provided with the outer ring 8a of the first concave portion for accommodating and limiting the first cooling member 2 and the second cooling member 51, and the heating surface of the first cooling member 2 and the cooling surface of the second cooling member 51 are attached to each other. The heat sink 3 is disposed on a side of the second cover 8 facing away from the first cover 4, and is thermally coupled to the second panel 49. When the skin treatment device is in the cold compress mode, heat generated by the heat generating surface of the first refrigerating element 2 during operation can be conducted to the heat radiating element 3 through the second panel part 49, so that the temperature environment inside the skin treatment device is suitable, and the service life of the device and the structural stability of the skin treatment device are not influenced by overheating.
