[0037] In existing technologies, each cryo-whitening method has a corresponding cryo-whitening head structure. When changing to a different cryo-whitening method, the corresponding whitening head structure must be replaced. However, since each whitening device usually only has a single whitening head, when the whitening head is replaced, the entire whitening device must be replaced. It is not possible to replace the whitening head separately on the same cold source as the whitening device, which causes inconvenience to users and affects the user experience and efficiency.

[0038] In response to the aforementioned problems with cryo-whitening heads and cryo-whitening devices, this utility model proposes a cryo-whitening head and cryo-whitening device to solve the technical problem of poor compatibility when different whitening head bodies are installed on the same cold source in the prior art, so as to optimize the user experience and efficiency of cryo-whitening heads and whitening devices.

[0039] To make the utility model's objectives, features, and advantages more apparent and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0040] Please see Figure 1 , Figure 2 , Figure 7 and Figure 8 Or refer to Figure 3 , Figure 4 , Figure 7 and Figure 8 Or refer to Figures 5 to 8 The first aspect of this utility model provides a cryo-hair whitening method, comprising:

[0041] Mounting base 1, mounting base 1 is equipped with a cooling component 10 and a cooling column 11, the cooling column 11 is connected to the cooling surface of the cooling component 10 for heat conduction, and at least part of the outer wall of the cooling column 11 is exposed outside the mounting base 1;

[0042] The whitening head body 2 is for contact with the skin. The whitening head body 2 is provided with a cooling insertion hole 20. The whitening head body 2 and the mounting base 1 can be detachably assembled.

[0043] When the whitening head body 2 is assembled on the mounting base 1, the cooling column 11 is inserted into the cooling insertion hole 20.

[0044] It should be noted that the cooling connection between the cooling column 11 and the cooling surface of the cooling component 10 can be achieved by the cooling column 11 directly contacting the cooling surface or by connecting the cooling column 11 and the cooling surface through thermally conductive adhesive. Since the whitening head body 2 and the mounting base 1 are detachably connected, the detachable connection method includes one or more of magnetic connection, snap-fit ​​connection, and threaded connection. That is, the whitening head body 2 and / or the mounting base 1 are provided with mutually cooperating detachable connectors 26. The detachable connectors 26 include one or more of magnetic connectors, snap-fit ​​connectors, and threaded connectors. Of course, other detachable connection methods and connectors in the field of beauty and whitening equipment can also be used.

[0045] During the operation of this embodiment, the cooling surface of the cooling component 10 of the mounting base 1 will transfer the cold energy to the cooling column 11. When the whitening head body 2 is inserted into the cooling column 11, the cold energy of the cooling column 11 will be transferred to the inner wall of the cooling insertion hole 20 of the whitening head body 2, and the cold energy of the cooling insertion hole 20 will be transferred to the end face of the whitening head body 2 that contacts the skin, so as to meet the needs of the whitening head body 2 in contact with the skin.

[0046] In the application of this embodiment, when the user needs to perform beauty and whitening treatment, the low-temperature whitening head 2 is brought into contact with the skin to be treated to inhibit the activity of skin melanocytes, help lighten spots, and at the same time cause skin blood vessels to constrict, reduce sebum secretion, and promote skin metabolism.

[0047] In another application of this embodiment, when a user needs to perform whitening for different purposes, the user can replace different whitening head bodies 2; then, align the cooling column 11 of the mounting base 1 with and insert it into the cooling insertion hole 20 of the whitening head body 2, and at the same time detachably connect the whitening head body 2 to the mounting base 1 to fix the whitening head body 2 on the mounting base 1 to prevent shaking or detachment during use.

[0048] As can be seen from the above working and application process, different whitening head bodies 2 and the same mounting base 1 can be replaced and installed on the same cold source through the cooling connection structure of the cooling column 11 and the cooling insertion hole 20. Users can choose different whitening head bodies 2 to assemble and use on the same cold source according to their needs, avoiding the situation where the cold source or beauty device must be replaced together when replacing different whitening head bodies 2, thereby optimizing the user experience and improving the efficiency of use.

[0049] Please see Figure 1 and Figure 2 , or see Figure 3 and Figure 4 , or see Figure 5 and Figure 6 In one specific embodiment, a feasible structure for the whitening head body 2 is further provided. The whitening head body 2 includes a contact end 21 for contacting the skin and a connecting end 22 for connecting to the mounting base 1. The contact end 21 and the connecting end 22 are arranged opposite to each other, that is, the contact end 21 is located at... Figure 2 The top of the Sino-US white-headed body 2, the connecting end 22 is located at Figure 2 At the bottom of the Sino-US white head body 2, the cooling insertion hole 20 is arranged along the direction from the connecting end 22 to the contact end 21, that is, the cooling insertion hole 20 is arranged along... Figure 2 The vertical arrangement of the head, the contact end 21, the cooling insertion hole 20 and the connecting end 22 are coaxial; when the whitening head body 2 is assembled on the mounting base 1, the cooling column 11 is inserted into the cooling insertion hole 20. The cooling column 11 is coaxial with the contact end 21 and the connecting end 22, which is very convenient for assembly and has high structural stability.

[0050] In one embodiment, such as Figure 1 and Figure 2 , or as Figure 3 and Figure 4 As shown, a feasible structure for the cooling insertion hole 20 is further provided. The cooling insertion hole 20 is a cooling through hole, that is, one end of the cooling through hole is located at the connecting end 22, and the other end of the cooling through hole is located at the contact end 21. The entire cooling insertion hole 20 penetrates the contact end 21 and the connecting end 22 of the whitening head body 2. When any whitening head body 2 is assembled on the mounting base 1, the end of the cooling column 11 away from the mounting base 1 is exposed outside the whitening head body 2. When the whitening head body 2 is assembled on the mounting base 1 and is running, a portion of the cold energy of the cooling column 11 will be directly transferred to the whitening head body 2 adjacent to the cooling column 11. At the end of the contact end 21, another part of the cold energy of the cooling column 11 is first transferred to the whitening head body 2 to form a uniform ring-shaped low temperature area. Since the cold energy of the whitening head body 2 is transferred through the cooling column 11, the temperature of the cooling column 11 is lower than the temperature of the whitening head body 2 on the same side of the contact end 21. When the cryo-whitening head comes into contact with the skin, the cooling column 11 will form a low temperature area in contact with the skin, while the whitening head body 2 will form a secondary low temperature area in contact with the skin. The secondary low temperature area is arranged around the low temperature area, thereby performing cryo-whitening treatment on the skin in a temperature zoning manner.

[0051] In another embodiment, such as Figure 5 and Figure 6 As shown, another feasible structure for the cooling insertion hole 20 is provided. The cooling insertion hole 20 is a blind cooling hole, and the opening end of the blind cooling hole is located at the connection end 22. That is, the entire cooling insertion hole 20 only has an opening on the connection end 22 of the whitening head body 2. When any whitening head body 2 is assembled on the mounting base 1, the end of the cooling column 11 away from the mounting base 1 is hidden inside the whitening head body 2. When the whitening head body 2 is assembled on the mounting base 1, the cold energy of the cooling column 11 will be transferred to the whitening head body 2 first, forming a uniform circular low temperature area on the contact end 21 of the whitening head body 2. When the whitening head comes into contact with the skin, the whitening head body 2 can perform uniform freezing and whitening treatment on the skin.

[0052] It should be understood that when the cooling insertion hole 20 of the whitening head body 2 is a cooling through hole, the cooling column 11 can be exposed outside the whitening head body 2. The ultra-low temperature energy is concentrated on the skin through the cooling column 11 to form a point-like focused cryo-whitening treatment. When the cooling insertion hole 20 is a cooling blind hole, the cooling column 11 is hidden inside the whitening head body. The whitening head body 2 as a whole contacts the skin. The contact end surface of the whitening head body 2 is larger than that of a single cooling column 11, which can form a surface-like cryo-whitening treatment.

[0053] The whitening head body 2 in the above embodiment has two possible structures for its cooling insertion hole 20: a blind hole and a through hole. When the cooling insertion hole 20 on the whitening head body 2 is a blind hole, the cooling column 11 is located inside the whitening head body 2 when it is assembled with the mounting base 1. When the whitening head comes into contact with the skin, only the whitening head body 2 will come into contact with the skin to form a uniform low-temperature freezing area on the skin. When the cooling insertion hole 20 on the whitening head body 2 is a through hole, the cooling column 11 is exposed outside the contact end 21 of the whitening head body 2 when it is assembled with the mounting base 1. When the whitening head comes into contact with the skin, both the whitening head body 2 and the cooling column 11 will come into contact with the skin. Since the cooling capacity of the contact end 21 of the whitening head body 2 is... The cooling energy is transferred through the cooling surface of the cooling component 10, the cooling column 11, and the whitening head body 2. During this transfer process, the cooling energy is transferred through at least two different media, resulting in significant cooling loss and a large temperature increase. However, the cooling energy at the end of the cooling column 11 that contacts the skin is transferred through the cooling surface of the cooling component 10 and the cooling column 11. During this transfer process, the cooling energy is transferred through only one different medium, resulting in less cooling loss and a smaller temperature increase. Therefore, the temperature at the end of the cooling column 11 that contacts the skin is higher than the temperature of the whitening head body 2, thus creating two freezing zones with different temperatures on the skin. Both systems aim to provide cryotherapy to the skin, but due to the different structures of the cooling port 20, they can achieve different treatment purposes on the skin. Those skilled in the art can choose according to their needs.

[0054] Please refer to Figures 7 to 10 In one specific embodiment, in order to form a cold flow concentration effect at the contact end 21, the cold flow concentrator 11 is a narrowing column along the direction from the refrigeration component 10 to the cold flow concentrator 11. The narrowing column can be a stepped narrowing column, a gradual narrowing column, or a combination of stepped and gradual narrowing columns. When the cold flow concentrator 11 conducts cold, the narrowing structure of the cold flow concentrator 11 itself can cause the cold energy to be guided by the narrowing structure. As the cross-sectional area of ​​the cold flow concentrator 11 becomes smaller, the cold flow gathers in the narrowing section, increasing the cold flow density and significantly enhancing the local cold conduction intensity, so that the cold energy is better concentrated at the end of the cold flow concentrator 11 adjacent to the contact end 21.

[0055] The cooling column 11 includes multiple column segments connected in sequence. The diameter of any column segment is a constant diameter or gradually decreases along the direction from the cooling component 10 to the cooling column 11. Along the direction from the cooling component 10 to the cooling column 11, the diameters of the multiple middle column segments decrease sequentially. The diameter of the column segment closest to the mounting base 1 is greater than the diameter of the column segment furthest from the mounting base 1, thus forming a stepped narrowing column, a gradually narrowing column, or a combination of stepped and gradually narrowing columns.

[0056] It should be noted that the multiple column segments of the cooling column 11 can be multiple constant diameter segments, with the diameter of each constant diameter segment decreasing sequentially along the direction from the connecting end 22 to the contact end 21, thus forming a stepped narrowing column; the multiple column segments of the cooling column 11 can be multiple variable diameter segments, with the diameter of each variable diameter segment gradually decreasing along the direction from the connecting end 22 to the contact end 21, thus forming a gradual narrowing column; the multiple column segments of the cooling column 11 can also have some constant diameter segments and some variable diameter segments, with the diameter of each constant diameter segment decreasing sequentially along the direction from the connecting end 22 to the contact end 21, and adjacent constant diameter segments are connected by variable diameter segments with gradually decreasing diameters, thus forming a stepped-gradual narrowing column.

[0057] In one embodiment, such as Figures 7 to 10 As shown, a feasible structure for the cooling column 11 is further provided. Along the direction from the refrigeration assembly 10 to the cooling column 11, the cooling column 11 includes a cooling base 110 and a cooling column body 111 connected in sequence. The cooling base 110 is connected to the refrigeration assembly 10 in a cooling conductive manner, and the cooling column body 111 is exposed outside the mounting base 1. The radial distance of the cooling base 110 is greater than the radial distance of the cooling column body 111. The narrowing design of the cooling column 11 guides the cold energy from the large cross-section cooling base 110 to the small cross-section cooling column 11, making the cold energy conduction more concentrated and forming a cold flow concentration effect.

[0058] In this embodiment, as Figure 9 and Figure 10As shown, a feasible structure for the cooling column 111 is further provided. Along the direction from the cooling substrate 110 to the cooling column 111, the cooling column 111 includes a first column segment 1110, a second column segment 1111, a third column segment 1112, a fourth column segment 1113, and a fifth column segment 1114 connected sequentially. The first column segment 1110 is connected to the cooling substrate 110, and its diameter is constant, meaning it maintains a constant diameter along its axial direction, and its diameter is smaller than the diameter of the cooling substrate 110. The diameter of the second column segment 1111 gradually narrows along the direction adjacent to the cooling column 111, and its maximum diameter is smaller than that of the first column segment 1110. The diameter of the third column segment 1112 gradually narrows along the direction adjacent to the cooling column 111, and its maximum diameter is smaller than that of the second column segment 1112. The minimum diameter of column segment 1111; the diameter of the fourth column segment 1113 is a constant diameter; the diameter of the fifth column segment 1114 gradually narrows along the direction of the adjacent cooling column 111, and the maximum diameter of the fifth column segment 1114 is smaller than that of the fourth column segment 1113; wherein, the axial length of the fourth column segment 1113 is greater than the axial length of the fifth column segment 1114, the axial length of the fifth column segment 1114 is greater than the axial length of the second column segment 1111, and the axial length of the second column segment 1111... The length of the fifth column segment 1114 is greater than the axial length of the first column segment 1110 and the third column segment 1112, and the axial lengths of the first column segment 1110 and the third column segment 1112 are similar. The slope of the narrowing slope of the second column segment 1111 is similar to that of the third column segment 1112, while the slope of the narrowing slope of the fifth column segment 1114 is greater than that of the narrowing slope of the second column segment 1111 and the third column segment 1112, thus forming a column that includes a stepped-gradual narrowing.

[0059] Please refer to Figure 2 or refer to Figure 4 or refer to Figure 6 Based on the above embodiments, in one specific embodiment, in order to enhance the cold flow concentration effect, the cold-conducting insertion hole 20 is a narrowed hole. The narrowed hole can be a stepped narrowed hole, a gradual narrowed hole, or a stepped-gradient narrowed hole. When the cold-conducting column 11 is inserted into the cold-conducting insertion hole 20, the cold energy of the cold-conducting column 11 will be transferred to the internal air of the cold-conducting insertion hole 20. When the cold air inside the cold-conducting insertion hole 20 is transferred to the contact end 21, it will be guided by the tapered structure of the cold-conducting insertion hole 20. The cold air is concentrated and guided to a smaller cross-sectional area during the conduction process, and less cold energy is lost. Furthermore, the narrowed channel can increase the fluid flow rate, accelerate the cold energy transfer, and enhance the freezing effect.

[0060] The cooling insertion hole 20 includes multiple sequentially connected aperture segments; the aperture of any aperture segment is a constant diameter or gradually decreases in size along the direction from the connecting end 22 to the contact end 21; along the direction from the connecting end 22 to the contact end 21, the apertures of the multiple aperture segments in the middle decrease in size sequentially; wherein, the aperture of the aperture segment closest to the contact end 21 is smaller than the aperture of the aperture segment furthest from the contact end 21, thereby forming a stepped-gradient narrowing hole.

[0061] It should be noted that the multiple diameter segments of the cooling guide hole 20 can be multiple constant diameter segments, which refer to segments that maintain a constant diameter in the axial direction. Along the direction from the connecting end 22 to the contact end 21, the diameter of each constant diameter segment decreases sequentially, thus forming a stepped narrowing hole. The multiple diameter segments of the cooling guide hole 20 can also be multiple variable diameter segments, with the diameter of each variable diameter segment gradually decreasing along the direction from the connecting end 22 to the contact end 21, thus forming a gradual narrowing hole. Alternatively, some of the multiple diameter segments of the cooling guide hole 20 can be constant diameter segments and some can be variable diameter segments. Variable diameter segments refer to segments whose diameter changes in the axial direction. Along the direction from the connecting end 22 to the contact end 21, the diameter of each constant diameter segment decreases sequentially, and adjacent constant diameter segments are connected by variable diameter segments with gradually decreasing diameters, thus forming a stepped-gradual narrowing hole.

[0062] In this embodiment, along the direction from the connecting end 22 to the contact end 21, the cooling insertion hole 20 specifically includes a first aperture segment 200, a second aperture segment 201, a third aperture segment 202, and a fourth aperture segment 203 connected in sequence; the aperture of the first aperture segment 200 is a constant aperture, the aperture of the second aperture segment 201 gradually decreases along the direction from the connecting end 22 to the contact end 21, the aperture of the third aperture segment 202 is a constant aperture or gradually decreases along the direction from the connecting end 22 to the contact end 21, and the aperture of the fourth aperture segment 203 gradually decreases along the direction from the connecting end 22 to the contact end 21.

[0063] Please refer to Figures 7 to 9 , Figure 12Based on the above embodiments, in a specific embodiment, a connection method that can be realized between the cooling column 11 and the mounting base 1 is further provided. The mounting base 1 is provided with a first mounting groove 12, a second mounting groove 13 is provided in the first mounting groove 12, and a mounting through hole 14 is provided in the second mounting groove 13. Along the direction from the cooling assembly 10 to the cooling column 11, the cooling column 11 includes a cooling base 110 and a cooling column body 111, and the cooling base 110 is connected to the cooling column body 111. The cooling base 110 is located in the second mounting groove 13, and the cooling column body 111 extends out of the mounting through hole 14. The diameter of the cooling base 110 is larger than the diameter of the cooling column body 111. The cooling base 110 and the cooling column body... A step is formed at the connection of 111 to engage the bottom surface of the second mounting groove 13; the cooling component 10 is located on the side of the cooling base 110 away from the cooling column 111, the cooling component 10 abuts against the cooling base 110, and the cooling component 10 is connected and fixed to the first mounting groove 12 so that the cooling component 10 and the mounting base 1 clamp the cooling base 110. The connection and fixation between the cooling component 10 and the first mounting groove 12 is configured to be fixed by a threaded part. With this assembly method, the cooling column 11 and the cooling component 10 can be installed on the mounting base 1, and the cooling column 11 abuts against the cooling component 10 so as to transfer the cooling capacity of the cooling component 10 to the cooling column 11.

[0064] In one embodiment, such as Figure 7 As shown, to facilitate the installation of the whitening head body 2 and the mounting base 1, the second mounting groove 13 extends along the direction from the cooling base 110 to the cooling column 111, so that a foolproof protrusion 15 is formed on the surface of the mounting base 1 away from the cooling base 110. That is, the wall of the second mounting groove 13 extending outward protrudes to form a foolproof protrusion 15 on the surface of the mounting base 1 near the cooling column 11. The opening of the cooling insertion hole 20 near the connecting end 22 matches the shape of the foolproof protrusion 15. The inner sidewall of the cooling insertion hole 20 is provided with a foolproof notch 204 for accommodating the foolproof protrusion 150. During the assembly process of the whitening head body 2, due to the setting of the foolproof protrusion 150 and the foolproof notch 204, the whitening head body 2 can only be installed in a specific direction, ensuring that the whitening head body 2 and the mounting base 1 are correctly assembled and reducing unnecessary operational errors.

[0065] In this embodiment, as Figure 11 As shown, the first diameter section 200 of the cooling insertion hole 20 matches the shape of the anti-fooling protrusion 15. The inner sidewall of the first diameter section 200 is provided with an anti-fooling notch 204 for accommodating the anti-fooling protrusion 150, so that the whitening head body 2 and the mounting base 1 can be installed in an anti-fooling manner.

[0066] Please refer to Figure 2 , Figure 4 and Figure 6In one specific embodiment, in order to improve the cold transfer efficiency of the cooling column 11 and reduce unnecessary cold loss, when the cooling column 11 is inserted into the cooling insertion hole 20, an annular gap 19 is formed between the outer peripheral wall of the cooling column 11 and the inner peripheral wall of the cooling insertion hole 20. The annular gap 19 is arranged near the connection end 22, that is, the annular gap 19 is located at the bottom of the cooling insertion hole 20 and the cooling column 11. When the cooling column 11 conducts cooling, since the cooling column 11 will not contact the bottom of the whitening head body 2 near the base of the mounting base 1, the cold energy of the cooling column 11 is maximized. The cold energy is transferred to one end of the contact end 21 of the adjacent whitening head body 2 and then contacts the whitening head body 2. The efficiency of cold energy transfer to the contact end 21 of the whitening head body 2 is high. That is, an annular gap 19 is formed between the bottom of the cold conducting column 11 and the bottom of the cold conducting hole 20. The cold energy at the bottom of the cold conducting column 11 will be preferentially transferred along the smaller cold conducting column 11, avoiding the problem of low cold energy transfer efficiency caused by most of the cold energy at the bottom of the cold conducting column 11 being transferred to the bottom of the whitening head body 2 first and then slowly transferred to the contact end 21 of the whitening head body 2 through the larger whitening head body 2.

[0067] Based on the above embodiments, in this embodiment, as Figure 2 , Figure 4 and Figure 6 As shown, the first column segment 1110, the second column segment 1111, and the third column segment 1112 of the cooling column 11 will all form an annular gap 19 with the first aperture segment 200 and / or the second aperture segment 201 of the cooling insertion hole 20. That is, the bottom of the cooling column 11 will not be in direct contact with the bottom of the cooling insertion hole 20, so as to avoid the problem of low cooling efficiency caused by premature transfer of cold energy.

[0068] In one embodiment, such as Figure 9 As shown, in order to realize the temperature detection of the cooling column 11, a temperature sensor 16 is also installed on the mounting base 1; the cooling column 11 is provided with an insertion hole 112, and the temperature sensor 16 is located in the insertion hole 112. The temperature sensor 16 is used to detect the temperature of the cooling column 11. When the cooling column 11 conducts cooling, the temperature sensor 16 can detect the current cooling temperature of the cooling column 11. The user can monitor in real time whether the structure of the cooling column 11 meets the requirements of cryo-whitening, thereby improving the intelligence level of the device.

[0069] Please refer to Figures 1 to 6 Based on the above embodiments, in this embodiment, the number of whitening head bodies 2 is multiple, and the multiple whitening head bodies 2 include a treatment head 2a for ice therapy muscles (see...). Figure 5 and Figure 6 ), Ice-moisturizing head 2b for ice therapy eyes (see) Figure 3 and Figure 4 ) and the cryo-head 2c for focused ice therapy (see Figure 1 and Figure 2 The cooling insertion hole 20 of treatment head 2a is a blind cooling hole, which only penetrates the connecting end 22 of treatment head 2a. The cooling insertion hole 20 of ice-lubricating head 2b is a through cooling hole, with both ends of the through cooling hole located at the connecting end 22 and the contact end 21 of ice-lubricating head 2b. The cooling insertion hole 20 of freezing head 2c is a through cooling hole, located at the connecting end 22 and the contact end 21 of freezing head 2c. The diameter of the contact end 21 of treatment head 2a is larger than that of the contact end 21 of ice-lubricating head 2b. Treatment head 2a is used for treatment of larger areas of the face or body, while ice-lubricating head 2b is used for the eyes. The diameter of the contact end 21 of ice-lubricating head 2b is larger than that of freezing head 2c. The contact end 21 of head 2c has a small diameter. Due to its small diameter, the freezing head 2c has the lowest operating temperature and is used for specific areas of cryotherapy for spot removal. In practice, the freezing head 2c, with its smallest diameter and lowest operating temperature, can achieve highly effective melanin inhibition and minimally invasive recovery during whitening, making it especially suitable for treating small areas of pigmentation and sensitive skin. The medium-diameter cooling head 2b expands the range of action and can relieve fatigue, reduce swelling, repair, and provide adjunctive treatment around the eyes. The treatment head 2a, with its large diameter, can be used on larger areas such as the face or body, increasing the areas that can be treated with cryotherapy.

[0070] In this embodiment, when the treatment head 2a is mounted on the mounting base 1, the cooling column 11 is concealed within the treatment head 2a. During treatment, the treatment head 2a performs single-temperature zone muscle ice therapy with a large-area contact end 21. When the ice-lubricating head 2b is mounted on the mounting base 1, the cooling column 11 is exposed outside the ice-lubricating head 2b. During treatment, the ice-lubricating head 2b performs multi-temperature zone muscle ice therapy with a medium-area contact end 21. When the freezing head 2c is mounted on the mounting base 1, the cooling column 11 is exposed outside the ice-lubricating head 2b. During treatment, the freezing head 2c performs multi-temperature zone muscle ice therapy with a small-area contact end 21.

[0071] The multi-temperature zones of the cooling head 2b and the freezing head 2c refer to the fact that the cold energy of the contact end 21 of the whitening head body 2 is transferred through the cooling surface of the cooling component 10, the cooling column 11, and the whitening head body 2. In this process, the cold energy is transferred through at least two different media, resulting in a large loss of cold energy and a large temperature rise. On the other hand, the cold energy of the end of the cooling column 11 that is in contact with the skin is transferred through the cooling surface of the cooling component 10 and the cooling column 11. In this process, the cold energy is transferred through only one different medium, resulting in a small loss of cold energy and a small temperature rise. Therefore, the temperature of the end of the cooling column 11 that is in contact with the skin is higher than the temperature of the whitening head body 2, so as to form two freezing zones with different temperatures on the skin.

[0072] In one embodiment, such as Figures 1 to 4As shown, at least one whitening head body 2 includes a head body 23 and a base body 24; the head body 23 is mounted on the base body 24, and the radial distance of the head body 23 gradually decreases along the direction from the base body 24 to the head body 23. With this narrowing structure, the contact area of ​​the contact end 21 is small enough to perform focused cryotherapy on the skin. Specifically, the ice-moisturizing head 2b for ice therapy on the eyes and the freezing head 2c for focused ice therapy are both narrow whitening head bodies 2, that is, both the ice-moisturizing head 2b and the freezing head 2c can perform treatment by focused cryotherapy. The ice-moisturizing head 2b can perform focused cryotherapy on the eyes, which is especially suitable for sensitive areas such as the eyes; while because the diameter of the freezing head 2c is further reduced, it can perform focused cryotherapy on localized small-area pigmentation.

[0073] In this embodiment, as Figures 1 to 4 As shown, a gripping groove 25 is formed between the connection between the head body 23 and the base body 24. The gripping groove 25 on the narrowed whitening head body 2 makes it convenient for users to pick up the whitening head body 2. Especially when whitening liquid is applied to the whitening head body 2, the surface of the whitening head body 2 is very slippery. The gripping groove 25 can prevent the whitening head body 2 from slipping off the hand and makes it convenient for users to pick up.

[0074] In one embodiment, such as Figures 3 to 6 As shown, at least one whitening head body 2 is equipped with an electrode assembly 3; the electrode assembly 3 includes multiple electrodes 30, which are used to connect to an external circuit. The multiple electrodes 30 are all located on the contact end 21 of the whitening head body 2, and are arranged circumferentially around the axis of the cooling inlet 20. In specific implementation, the whitening head body 2 has both electrostimulation and cryotherapy functions. The circumferentially evenly arranged electrodes 30 can provide uniform electrostimulation treatment to the patient's skin, thus forming a synergistic combination of cryotherapy and electrostimulation on the whitening head body 2. The electrostimulation formed by the electrode assembly 3 can open skin cells through electroporation, promoting the absorption of cosmetics. Electroporation is painful, but combining it with cryotherapy can reduce the pain. Furthermore, the opening of cells during electroporation is reversible; cryotherapy can lock the cells in place after the opening, prolonging the cell closure time and promoting the absorption of skincare products. Specifically, both the treatment head 2a for muscle cryotherapy and the ice-moisturizing head 2b for eye cryotherapy are equipped with electrode components 3 to combine electrotherapy and cryotherapy functions. That is, treatment head 2a can achieve combined electrostimulation and cryotherapy on larger areas such as the face or body, improving the cosmetic effect of facial or body skin; while ice-moisturizing head 2b can achieve combined electrostimulation and cryotherapy on the eyes, improving the cosmetic effect of the eye area.

[0075] Based on the above embodiments, in one embodiment, as follows: Figure 5 and Figure 6As shown, the whitening head body 2, which is equipped with electrode assembly 3, also has a light assembly 4. The light assembly 4 includes multiple light groups 40, wherein the light groups 40 use LED beads or other feasible light beads, and the light groups 40 are used to connect to external circuits. The multiple light groups 40 are all located on the contact end 21 of the whitening head body 2, and the multiple light groups 40 are arranged circumferentially around the axis of the cooling insertion hole 20. There is at least one light group 40 between two adjacent electrodes 30. In specific implementation, the whitening head body 2 simultaneously has electrostimulation therapy function, cryotherapy function, and phototherapy function. The circumferentially evenly arranged electrodes 30 and light groups 40 can provide uniform electrostimulation therapy and phototherapy to the patient's skin, thereby whitening the skin of the whitening head body 2. This creates a synergistic combination of cryotherapy, electrostimulation therapy, and light therapy. The light component 4 accelerates the absorption of skincare products applied to the skin, and the combined effects of electrostimulation and cryotherapy enhance drug absorption. Specifically, the treatment head 2a for ice therapy muscles is equipped with an electrode component 3 and a light component 4, so that the whitening head body 2 has a combination of electrotherapy, light therapy, and cryotherapy functions. That is, the treatment head 2a can perform combined electrostimulation, cryotherapy, and light therapy on larger areas such as the face or body, improving the cosmetic effect of facial or body skin. The ice-moisturizing head 2b can perform combined electrostimulation, cryotherapy, and light therapy on the eyes, improving the cosmetic effect of the skin around the eyes.

[0076] In this embodiment, as Figure 7 As shown, the mounting base 1 is provided with multiple first contacts 17 for supplying power to the electrode 30, multiple second contacts 18 for supplying power to the lamp assembly 40, and a contact detection sensor 5. The first contacts 17 and the second contacts 18 are arranged on the surface of the mounting base 1 adjacent to the cooling column 11 and are arranged circumferentially around the cooling column 11. The contact detection sensor 5 is used to detect the contact between the electrode 30 and the first contacts 17, and to detect the contact between the lamp assembly 40 and the second contacts 18, so as to detect problems such as poor contact in a timely manner.

[0077] Please refer to Figure 8 and Figure 9 In one specific embodiment, a feasible structure for the cooling assembly 10 is further provided. The cooling assembly 10 includes a semiconductor cooling chip 100 and a heat sink 101. The cooling surface of the semiconductor cooling chip 100 is bonded to the cooling column 11 by thermally conductive silicone grease. The heat dissipation surface of the semiconductor cooling chip 100 is thermally connected to the heat sink 101. The heat sink 101 is used to dissipate the heat of the semiconductor cooling chip 100.

[0078] Please refer to Figure 5 and Figure 6Based on the above embodiments, this embodiment further provides a feasible structure for a treatment head 2a for cryotherapy of muscles. The contact end 21 of the treatment head 2a is provided with multiple electrodes 30, multiple lamp groups 40, and a contact cover for sealing the cooling insertion hole 20. The multiple electrodes 30 are arranged circumferentially around the axis of the cooling insertion hole 20, and the multiple lamp groups 40 are arranged circumferentially around the axis of the contact cover. The multiple electrodes 30 and the multiple lamp groups 40 are arranged at intervals, that is, a lamp group 40 is provided between two adjacent electrodes 30, and an electrode 30 is provided between two adjacent lamp groups 40. When the treatment head 2a is assembled on the mounting base 1, the cooling column 11 is inserted into the cooling insertion hole 20 in a manner that is concealed within the treatment head 2a. During treatment, the cryotherapy of the treatment head 2a will perform cryotherapy on the skin in the same temperature zone, and it also has electrotherapy and phototherapy at the same time, which can perform combined treatment on the skin.

[0079] It should be noted that, since the cooling column 11 is embedded in the treatment head 2a when the treatment head 2a is assembled with the mounting base 1, only the surface of the contact end 21 of the treatment head 2a is in contact with the skin. The cooling energy of the surface of the contact end 21 of the treatment head 2a is transferred through the body of the treatment head 2a. The temperature at the center of the surface of the contact end 21 may be different from the temperature at the edge, but the difference is small. Therefore, the entire surface of the contact end 21 of the treatment head 2a is approximately considered to be a region of the same temperature.

[0080] In this embodiment, the outer diameter of the treatment head 2a is a constant diameter, that is, the entire treatment head 2a is a cylindrical structure; the contact end 21 of the treatment head 2a is provided with a contact cover hole for installing a contact cover, multiple electrode 30 mounting holes, and multiple lamp assembly 40 mounting holes; the contact cover hole communicates with the cooling insertion hole 20, and the contact cover is detachably installed in the contact cover hole by a threaded component, and the setting of the contact cover makes the cooling insertion hole 20 a blind hole; the electrode 30 mounting holes and the lamp assembly 40 mounting holes both penetrate the contact end 21 and the connection end 22, and the multiple electrode 30 mounting holes and the multiple lamp assembly 40 mounting holes all surround the contact cover. The holes are evenly arranged around the circumference, and the mounting holes of the electrode 30 and the mounting holes of the lamp assembly 40 are arranged at intervals. The electrode 30 is mounted on the side of the mounting hole of the electrode 30 near the contact end 21. The electrode contact head for electrical connection with the first contact 17 of the mounting base 1 is arranged on the side of the mounting hole of the electrode 30 away from the contact end 21. The connecting line of the electrode 30 connects the electrode contact head and the electrode 30. The lamp assembly 40 is mounted on the side of the mounting hole of the lamp assembly 40 near the contact end 21. The lamp assembly contact head is arranged on the side of the mounting hole of the lamp assembly 40 away from the contact end 21. The connecting line of the lamp assembly 40 connects the lamp assembly contact head and the lamp assembly 40.

[0081] The cooling insertion hole 20 of the treatment head 2a is a blind cooling hole. The cooling insertion hole 20 extends from the connecting end 22 to the contact end 21 and extends into the contact cover. Along the direction adjacent to the contact end 21, the cooling insertion hole 20 of the treatment head 2a includes a first aperture section 200, a second aperture section 201, a third aperture section 202, and a fourth aperture section 203. The first aperture section 200 has a constant aperture and is provided with a foolproof notch 204 for accommodating the foolproof protrusion 150. The second aperture section 201 has a linearly narrowing aperture. The third aperture section 202 extends into the contact cover, and its aperture is constant. The diameter of the third aperture section 202 matches the shape of the fourth column section 1113 of the cooling column 111, that is, the third aperture section 202 abuts against the fourth column section 1113 of the cooling column 111; the fourth aperture section 203 extends into the contact cover, and the aperture of the fourth aperture section 203 is also linearly narrowed. The fourth aperture section 203 matches the shape of the fifth column section 1114 of the cooling column 111, that is, the fourth aperture section 203 abuts against the fifth column section 1114 of the cooling column 111. When the cooling column 11 is inserted into the cooling insertion hole 20, an annular gap 19 is left between the first aperture section 200 and the second aperture section 201 and the cooling column 11.

During treatment, the ice-moistening head 2b, in conjunction with the cooling column 11, will perform cryotherapy on the skin with multiple temperature zones. The ice-moistening head 2b, which also has electrotherapy capabilities, can also perform combined treatment on the skin.

The head body 23 is mounted on the base body 24, and the radial distance of the head body 23 gradually decreases. A gripping groove 25 is formed between the head body 23 and the base body 24. The contact end 21 of the cooling head 2b is provided with a cooling insertion hole 20 and multiple electrode 30 mounting holes. The multiple electrode 30 mounting holes are evenly arranged around the circumference of the cooling insertion hole 20.

The diameter of the second diameter section 201 is linearly narrowed in the section adjacent to the first diameter section 200, and arc-shaped narrowed in the section away from the first diameter section 200. The third aperture segment 202 has a constant aperture and matches the shape of the fourth column segment 1113 of the cooling column 111, that is, the third aperture segment 202 abuts against the fourth column segment 1113 of the cooling column 111; the aperture of the fourth aperture segment 203 is also linearly narrowed, and the fourth aperture segment 203 matches the shape of the fifth column segment 1114 of the cooling column 111, that is, the fourth aperture segment 203 abuts against the fifth column segment 1114 of the cooling column 111. When the cooling column 11 is inserted into the cooling insertion hole 20, an annular gap 19 is left between the second aperture segment 201 and the cooling column 11.

During treatment, the cryotherapy head 2c in conjunction with the cold-conducting column 11 will perform focused cryotherapy on the skin with multiple temperature zones.

[0086] In this embodiment, the freezing head 2c includes a head body 23 and a base body 24; the head body 23 is mounted on the base body 24, the radial distance of the head body 23 gradually decreases, and a gripping groove 25 is formed between the connection between the head body 23 and the base body 24; a cold guiding insertion hole 20 is provided on the contact end 21 of the freezing head 2c.
