Abstract
Description
Technical Field
[0001] This utility model relates to the field of beauty instrument technology, and in particular to a treatment head and radiofrequency therapy device. Background Technology
[0002] Radiofrequency therapy devices use the energy generated by radiofrequency to heat and break down fat. The broken-down fat tissue is absorbed by the body's circulatory system and then excreted from the body, thereby achieving the effect of weight loss and fat reduction.
[0003] Radiofrequency ablation devices consist of a handpiece and a treatment head. The treatment head contains components such as a circuit board. To facilitate circuit board assembly and subsequent maintenance, the treatment head's outer shell typically includes a cover and a base plate. The circuit board is fixed to the base plate, and the cover is fitted over the base plate. The cover and base plate are secured together with several screws. When the circuit board or other components inside the treatment head malfunction and require repair, multiple screws need to be removed to disassemble the outer shell, making the process rather cumbersome. Utility Model Content

[0029] This utility model proposes a treatment head 100.
[0030] To achieve the above objectives, the treatment head 100 of this utility model includes a first housing 1, a second housing 2, and a third housing 3. The first housing 1 forms a first chamber with an upper opening. The first housing 1 is connected to the second housing 2. The second housing 2 forms a second chamber with a lower opening. The second housing 2 is docked with the first housing 1 so that the first chamber and the second chamber communicate to form a receiving cavity. The third housing 3 is sleeved on the circumferential surface of the first housing 1 and the second housing 2, and the third housing 3 is locked to the first housing 1 and the second housing 2 respectively. The treatment component 4 is installed in the receiving cavity.
[0031] This treatment head 100 is used to interface with the treatment handle 200. The treatment head 100 contains a first circuit board 41, and the treatment handle 200 contains a second circuit board. When the treatment head 100 and treatment handle 200 are interfaced, the first circuit board 41 and the second circuit board are electrically connected to form a complete radiofrequency therapy device. Traditional radiofrequency therapy heads typically consist of a housing and a base plate. The first circuit board is fixed to the base plate, and the housing is placed over the base plate. The housing and base plate are secured with several screws. Therefore, when the first circuit board or other components inside the treatment head malfunction and require repair, multiple screws need to be removed to disassemble the housing, making the process cumbersome.
[0032] Unlike traditional radiofrequency treatment heads, the treatment head 100 of this invention divides the outer shell into a first shell 1 and a second shell 2 that are interconnected. The first shell 1 encloses a first chamber with an upper opening, and the second shell 2 encloses a second chamber with a lower opening. The first shell 1 and the second shell 2 are docked, thereby connecting the first chamber and the second chamber to form a receiving cavity. Treatment components 4, such as a first circuit board 41, are disposed within the receiving cavity. Furthermore, this technical solution also includes a third shell 3 fitted around the periphery of the first shell 1 and the second shell 2. Specifically, a portion of the inner circumferential surface of the third shell 3 is fitted with the outer circumferential surface of the first shell 1, and a portion of the inner circumferential surface of the third shell 3 is fitted with the outer circumferential surface of the second shell 2. The third shell 3 is locked to both the first shell 1 and the second shell 2, thus locking the first shell 1 and the second shell 2 together.
[0033] The first housing 1, the second housing 2, and the third housing 3 are all detachably connected to each other. The connection relationships between the first housing 1, the second housing 2, and the third housing 3 include, but are not limited to, the following:
[0034] 1. The third housing 3 abuts against the second housing 2, and the third housing 3 is snapped into the first housing 1;
[0035] 2. The third housing 3 abuts against the second housing 2, and the third housing 3 is interference-fitted with the first housing 1;
[0036] 3. The third housing 3 is snapped into the second housing 2, and the third housing 3 is snapped into the first housing 1;
[0037] 4. The third housing 3 is snapped into the second housing 2, and the third housing 3 is interference-fitted with the first housing 1;
[0038] 5. The third housing 3 is interference-fitted with the second housing 2, and the third housing 3 is snap-fitted with the first housing 1;
[0039] 6. The third housing 3 is interference-fitted with the second housing 2, and the third housing 3 is interference-fitted with the first housing 1.
[0040] In summary, when the treatment component 4 inside the first housing 1 and the second housing 2 malfunctions and needs to be repaired, it is only necessary to disconnect the third housing 3 from the first housing 1 and the second housing 2, and pull out the third housing 3 to quickly disassemble the first housing 1 and the second housing 2 without having to unscrew multiple screws, making the operation convenient and quick.
[0041] In one embodiment, a first limiting block 11 is provided on the top surface of the side wall of the first housing 1, and a first limiting groove 21 is provided on the bottom surface of the side wall of the second housing 2. The first limiting block 11 is inserted into the first limiting groove 21 to achieve the limiting of the first housing 1 and the second housing 2.
[0042] The first housing 1 includes a bottom plate and a first side plate, which together form a first chamber. The second housing 2 includes a top plate and a second side plate, which together form a second chamber. (Refer to...) Figure 1 and Figure 3 The top surface of the first side plate has a first limiting block 11 protruding upwards. The first limiting blocks 11 are continuously arranged in a circumferential direction. The inner surface of the first limiting block 11 is flush with the inner surface of the first side plate. The thickness of the first limiting block 11 is less than the thickness of the first side plate. The bottom surface of the second side plate has a first limiting groove 21 that matches the first limiting block 11. The first limiting block 11 is inserted into the first limiting groove 21 to limit the first housing 1 and the second housing 2. Of course, in actual application, the first limiting block 11 can be a segmented arc-shaped block. In this case, multiple first limiting blocks 11 are provided, and the multiple first limiting blocks 11 are arranged in a circumferential interval. The number and position of the first limiting groove 21 correspond to the number and position of the first limiting blocks 11.
[0043] In another embodiment, a first limiting hole 14 is provided on the top surface of the side wall of the first housing 1, and a first limiting post 25 is provided on the bottom surface of the side wall of the second housing 2. The first limiting post 25 is inserted into the first limiting hole 14 to limit the first housing 1 and the second housing 2.
[0044] In this embodiment, a first limiting hole 14 is provided on the top surface of the first side plate and is positioned opposite to the first limiting hole 14. A first limiting post 25 is provided on the bottom surface of the second side plate and is positioned opposite to the first limiting hole 14. The diameter of the first limiting post 25 is the same as the diameter of the first limiting hole 14. The first limiting post 25 is inserted into the first limiting hole 14 to limit the first housing 1 and the second housing 2.
[0045] Of course, in actual application, the first housing 1 can be equipped with both the first limiting block 11 and the first limiting hole 14 to limit the second housing 2, and no restrictions are imposed here.
[0046] Regarding the snap-fit connection between the first housing 1 and the third housing 3, refer to... Figure 1 , Figure 2 , Figure 3 and Figure 5The outer side wall of the first housing 1 is recessed with a first slot 12, and the inner side wall of the third housing 3 is protruded with a first block 31 that matches the first slot 12. The first block 31 is inserted into the corresponding first slot 12 to achieve the engagement of the first housing 1 and the third housing 3. The number of first slots 12 is several, i.e., at least two. The number of first blocks 31 matches the number of first slots 12. Several first slots 12 are arranged circumferentially and spaced apart along the outer side wall of the first housing 1, and each first block 31 corresponds to a first slot 12. When there are two first slots 12, the two first slots 12 are arranged opposite each other. Of course, the number of first slots 12 can also be more than two. Multiple first slots 12 are evenly and spaced apart along the circumference of the first side plate; this is not limited here.
[0047] Furthermore, a second limiting block 13 is provided on the outer side wall of the first housing 1. The second limiting block 13 is located below the first slot 12. The bottom surface of the third housing 3 contacts and abuts against the top surface of the second limiting block 13 to achieve the limiting of the third housing 3 and the first housing 1.
[0048] Regarding the snap-fit connection between the second housing 2 and the third housing 3, refer to... Figure 1 , Figure 2 , Figure 4 and Figure 5 The outer side wall of the second housing 2 is recessed with a second slot 22, and the inner side wall of the third housing 3 is protruded with a second block 32. The second block 32 is inserted into the second slot 22 to achieve the engagement between the third housing 3 and the second housing 2. The number of second slots 22 is at least two. When there are two, the two second slots 22 are arranged opposite each other. When there are multiple first slots 12, they are arranged circumferentially at intervals along the outer side wall of the second housing 2. The number of second blocks 32 is the same as the number of second slots 22, and each second block 32 is arranged opposite to one second slot 22.
[0049] In one embodiment, reference is made to Figure 1 and Figure 2 The second housing 2 includes a first sub-housing 23 and a second sub-housing 24 connected together. The second sub-housing 24 is located above the first sub-housing 23 and together with the first sub-housing 23 forms a second chamber. The size of the second sub-housing 24 is smaller than that of the first sub-housing 23, that is, the diameter of the second sub-housing 24 is smaller than the diameter of the first sub-housing 23, or the length and width of the second sub-housing 24 are smaller than the length and width of the first sub-housing 23. The top of the third housing 3 has a protruding ring 33. The inner diameter of the protruding ring 33 is the same as the outer diameter of the second sub-housing 24. The circumferential inner surface of the protruding ring 33 fits against the circumferential outer surface of the second sub-housing 24, and the bottom surface of the protruding ring 33 fits against the top surface of the first sub-housing 23, so as to realize the snap-fit between the third housing 3 and the second housing 2.
[0050] Of course, in actual application, the second housing 2 can be provided with a second slot 22 and a protruding ring 33 at the same time to achieve engagement with the third housing 3.
[0051] Furthermore, in one embodiment of the present invention, a portion of the circumferential outer surface of the first sub-shell 23 is presented as an inclined slope.
[0052] It should be explained in detail that the first sub-shell 23 is narrower at the top and wider at the bottom. The first shell 1 is divided into an upper section, a middle section, and a lower section from top to bottom. The size of the upper section is smaller than that of the lower section, and the circumferential outer surface of the upper section is a vertical plane. The circumferential outer surface of the lower section is also a vertical plane. The middle section is located between the upper and lower sections to connect them, and its circumferential outer surface is an inclined slope. Correspondingly, the inner diameter of the third shell 3 matches the outer diameter of the second shell 2, and it is also designed to be narrower at the top and wider at the bottom. The circumferential inner surface of the third shell 3 is in contact with the circumferential outer surface of the second shell 2. Therefore, the inclined surface of the third shell 3 exerts a pressing effect on the inclined surface of the second shell 2, thereby increasing the pressing area between the third shell 3 and the second shell 2, making the engagement between the third shell 3 and the second shell 2 more stable.
[0053] Reference Figure 1 In this treatment head 100, the treatment component 4 includes a first circuit board 41 and a vibration motor 42. The first circuit board 41 is installed in a first chamber and fixedly connected to the bottom plate of the first housing 1. The vibration motor 42 is installed in a second chamber and fixedly connected to the top plate of the second housing 2. The vibration motor 42 is electrically connected to the first circuit board 41. When the treatment head 100 is docked with the treatment handle 200, the first circuit board 41 and the second circuit board inside the treatment handle 200 are electrically connected. The vibration motor 42 is used to generate vibrations on the skin to achieve a vibration massage effect, improving the user's comfort and experience.
