[0033] Figure 1 is an exploded view of the operating head of the contact type cosmetic instrument of the present application. Figure 2 is a perspective exploded view of the contact type cosmetic instrument.

[0034] As Figure 1 and Figure 2 described, the contact type cosmetic instrument 1 includes an operating head 10, a mounting bracket 20, and a circuit board 40. The operating head 10 has a contact surface 10a for contacting and cooling a skin site. The mounting bracket 20 has a first mounting position and a second mounting position. The operating head 10 is fixed to the mounting bracket 20 through the first mounting position. The circuit board 40 is fixed to the mounting bracket 20 through the second mounting position. The operating head 10 is located at the head of the cosmetic instrument 1. The mounting bracket 20 extends from the head of the cosmetic instrument 1 to the tail of the cosmetic instrument 1.

[0035] The contact type cosmetic instrument 1 works by discharging the operation head 10 to generate radio frequency or micro-current to stimulate the skin part, thereby obtaining the expected cosmetic effect. For this purpose, the operation head 10 needs to be powered by the circuit board 40. The application uses the mounting bracket 20 to fix the circuit board 40 and the operation head 10, the first mounting position of the mounting bracket 20 is at the head for mounting the operation head 10 and other components, and the second mounting position is the mounting part for mounting the circuit board 40 and other components, which are arranged in layers to reduce the size of the cosmetic instrument 1.

[0036] Optionally, the contact type cosmetic instrument 1 includes an isolation bracket 30 having two opposite sides; the mounting bracket 20 has a third mounting position for mounting the isolation bracket 30.

[0037] Optionally, the side of the mounting bracket 20 has a groove 201, and the second mounting position and the third mounting position are arranged in the groove 201. The second mounting position and the third mounting position are located at different depths of the groove 201, so that the circuit board 40 and the isolation bracket 30 are arranged in layers, and the second mounting position is away from the bottom of the groove 201 relative to the third mounting position.

[0038] Since the isolation bracket 30 is located between the circuit board 40 and the bottom of the groove 201, and the bottom of the groove 201 is usually the position where the heat pipe of the cosmetic instrument 1 is installed, the isolation bracket 30 can isolate heat and prevent the circuit board 40 from overheating, thereby protecting the circuit board 40. In addition, many precision devices are usually installed inside the cosmetic instrument 1, and the layered arrangement can prevent the circuit board 40 and these devices from interfering with each other during operation; most of these precision devices are relatively fragile, and installing these fragile elements on the isolation bracket 30 can effectively avoid interference of vibration and other factors on the elements.

[0039] For example, during the use of the cosmetic instrument 1, the cosmetic instrument 1 may be shaken, bumped or deformed during use, and if these fragile elements are not protected by the isolation bracket 30, the elements may collide with other components, the elements may be squeezed, and the service life of the cosmetic instrument 1 may be shortened.

[0040] Optionally, the distance from the second mounting position to the bottom of the groove 201 is between 1.5 and 3 times the distance from the third mounting position to the bottom of the groove 201.

[0041] The significance of such arrangement is that: first, through repeated design and verification of the inventor of the present application, when the ratio of the distance from the second mounting position to the bottom of the groove 201 to the distance from the third mounting position to the bottom of the groove 201 is between 1.5-3 times, the gap between the installed circuit board 40, the isolation support 30 and the bottom of the groove 201 is the most reasonable, and there will be no interference between the components. Moreover, since the circuit board 40 will generate heat, and the bottom of the groove 201 usually has a heat pipe, the reasonable distance between the circuit board 40, the isolation support 30 and the bottom of the groove 201 and the circuit board 40 and the isolation support 30 will be more conducive to good heat dissipation effect inside the beauty instrument 1, avoiding the case of local overheating of internal components.

[0042] In the case of ensuring reasonable gap and effective heat dissipation, the volume inside the beauty instrument 1 is as small as possible, which is the reason for setting the ratio of the distance from the second mounting position to the bottom of the groove 201 to the distance from the third mounting position to the bottom of the groove 201 between 1.5-3 times.

[0043] Optionally, the contact type beauty instrument 1 further comprises a first mounting plate 210 and a key assembly 410. The key assembly 410 is arranged on the first mounting plate 210; wherein the side wall of the groove 201 is provided with a step, the circuit board 40 is fixed in the groove 201 through the step, the isolation support 30 surrounds and is fixed to the first mounting plate 210, the two side surfaces of the isolation support 30 are arranged in parallel and spaced apart from the two surfaces of the first mounting plate 210, the first mounting plate 210 is fixed to the side wall of the groove 201 and is located on the side of the circuit board 40 away from the bottom of the groove 201.

[0044] The key assembly 410 is used for turning on and turning off the contact type beauty instrument 1, and the key assembly 410 can be further improved to set different gears to meet the requirements of different intensity of current or radio frequency.

[0045] Optionally, the contact type beauty instrument 1 comprises a second mounting plate 220, the circuit board 40 is mounted on the second mounting plate 220, the second mounting plate 220 is mounted on the step, and the second mounting plate 220 is arranged in spaced apart manner with the bottom of the groove 201.

[0046] The step is arranged in the groove 201 for fixing the second mounting plate 220, the key assembly 410 is mounted on the first mounting plate 210, and the first mounting plate 210 is fixed on the mounting support 20 through the inner wall of the groove 201, since the groove 201 provides a spaced apart space, the mounting support 20 will not interfere with each other when installing various components; the second mounting plate 220 is close to the bottom of the groove 201 but does not contact the bottom, so as to reduce the working influence on other components mounted on the mounting support 20; the arrangement of the step can more reasonably utilize the volume inside the groove 201, so that the components on the mounting support 20 are arranged in a more orderly manner, the positions of the components are reasonably divided, and the volume of the beauty instrument is effectively reduced, which is convenient for use.

[0047] Optionally, the first mounting plate 210 extends to the tail of the contact type beauty instrument 1, and an end of the first mounting plate 210 away from the operation head 10 is provided with a charging module 420 connected to the circuit board 40.

[0048] Optionally, the ratio of the length of the second mounting plate 220 to the length of the mounting bracket 20 is between 1.2 and 2, and the charging module 420 is spaced apart from the mounting bracket 20 by a distance of 1-3 cm.

[0049] The first mounting plate 210 extends to the tail of the contact type beauty instrument 1 and has a longer length, which is beneficial to the installation of small components other than the battery and improves the space utilization. The charging module 420 needs to be spaced apart from the mounting bracket 20 by a certain distance for better heat dissipation, and the distance is usually between 1 cm and 3 cm to meet the heat dissipation requirements of the beauty instrument 1. Considering the weight of the circuit board 40 and the bearing requirement of the mounting plate, the ratio of the length of the second mounting plate 220 to the length of the mounting bracket 20 is between 1.2 and 2. This ratio range is obtained by repeated design and verification by the inventor of the present application, and a larger or smaller length ratio will have higher requirements for the material of the mounting plate, which will increase the cost of the beauty instrument 1. In order to consider lower production cost, the present application limits the ratio of the length of the second mounting plate 220 to the length of the mounting bracket 20 to be between 1.2 and 2, so that the second mounting plate 220 can be made of conventional materials.

[0050] Optionally, the recess 201 of the beauty instrument 1 is provided with a mounting groove 230 for mounting the heat pipe 610, and the mounting groove 230 is arranged along the inner wall of the recess 201 and extends from the end of the mounting bracket 20 close to the operation head 10 to the end away from the operation head 10.

[0051] Figure 3 The present application is a contact type beauty instrument. As shown in Figure Three The beauty instrument 1 guides heat dissipation through the heat dissipation assembly 60, and the heat pipe 610 is connected to the heat dissipation member 620. The heat pipe 610 is arranged at the bottom of the recess 201 to contact all parts of the body, which not only improves the space utilization but also better realizes heat dissipation. Since the mounting groove 230 extends from the end of the mounting bracket 20 close to the operation head 10 to the end away from the operation head 10, the heat pipe 610 can extend to the tail of the mounting bracket 20, and the heat pipe 610 adopts an L-shaped structure to maximize the contact with all parts of the body of the beauty instrument 1, thereby achieving good heat dissipation effect.

[0052] Optionally, the mounting bracket 20 has a containing groove 240 arranged on the side of the first mounting position to contain part of the lead wire in the contact type beauty instrument 1.

[0053] The accommodation groove 240 can make the design of the mounting bracket 20 more neat and compact, and prevent the occurrence of faults caused by the disorder of the lead wire during installation.

[0054] Optionally, the mounting bracket 20 has a first guide part, the operating head 10 has a second guide part, the first guide part cooperates with the second guide part, and the first guide part and the second guide part move relative to each other to guide the installation of the operating head 10 on the mounting bracket 20.

[0055] Optionally, the first guide part is a guide groove 250, and the second guide part is a guide strip 110; the guide groove 250 is arranged on the side surface of the mounting bracket 20 close to one end of the operating head 10, and the guide strip 110 is arranged on the operating head 10 at a position corresponding to the guide groove 250, and the guide strip 110 slides along the guide groove 250 to guide the installation of the operating head 10 on the mounting bracket 20.

[0056] Figure 4 is a side view of the operating head of the contact type beauty instrument of the present application. As shown in Figure 4 the guide strip 110 on the operating head 10 corresponds to the guide groove 250 on the mounting bracket 20, and the design of sliding the guide strip 110 along the guide groove 250 to guide the installation of the operating head 10 on the mounting bracket 20 can facilitate the installation of the operating head 10.
