Description

Technical Field

[0001] The present invention relates to the technical field of laser hair removal devices, and specifically to a household laser hair removal device with fast assembly, tight sealing and waterproofing. Background Art

[0002] As a convenient beauty device, household laser hair removal devices have developed rapidly in the market in recent years. However, there are still problems in the prior art such as low assembly efficiency, insufficient sealing, poor waterproof performance, and contradictions between heat dissipation and protection design, which limit the reliability of the product and the user experience. The following analyzes from two aspects: the technical status quo and defects.

[0003] The shells of most household hair removal devices adopt a multi-component splicing design, which requires fixing with screws and installing sealing rings, resulting in cumbersome assembly steps. In addition, some products set sealing rings at the shell joints to achieve waterproofing, but precise alignment and multiple debugging are required, significantly reducing the production efficiency. For example, a waterproof protection device for a semiconductor laser in a semiconductor laser hair removal device disclosed in Patent CN213156400U uses a sealed O-ring and a silica gel pad to prevent water ingress and dust of the semiconductor laser. However, it will be found in actual use that the sealed O-ring and the silica gel pad are generally made of rubber material, and there will generally be problems that they will age and harden due to various chemical reactions after long-term use, resulting in a decrease in elasticity. This leads to a deterioration of the sealing effect at the sealing gap, resulting in the failure of the sealing and waterproofing effect after long-term use, affecting the service life of the household laser hair removal device.

[0004] Therefore, we provide a household laser hair removal device with fast assembly, tight sealing and waterproofing to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a household laser hair removal device with fast assembly, tight sealing and waterproofing to solve the problems mentioned in the above background art that the shells of most household hair removal devices adopt a multi-component splicing design, which requires fixing with screws and installing sealing rings, resulting in cumbersome assembly steps, and that the traditional sealing mostly uses sealed O-rings and silica gel pads, which are generally made of rubber material, and there will generally be problems that they will age and harden due to various chemical reactions after long-term use, resulting in a decrease in elasticity. This leads to a deterioration of the sealing effect at the sealing gap, resulting in the failure of the sealing and waterproofing effect after long-term use, affecting the service life of the household laser hair removal device.

[0013] For the fast-assembling, tightly sealed and waterproof household laser hair removal device as described above: The extrusion component includes a slide plate slidably clamped inside the third groove. Fourth wedge-shaped blocks and push plates are respectively fixed at both ends of the slide plate. A limiting component for the movement of the slide plate is arranged in the third groove.

[0017] A fast-assembling, tightly sealed and waterproof household laser hair removal device as described above: The stopping component includes a fifth wedge block fixed to the partition plate and a second spring groove opened on the clamping plate. A block is movably clamped inside the second spring groove. A sixth wedge block penetrating through the clamping plate is fixed to the top of the block, and a second spring is arranged at the bottom. Two ends of the second spring are respectively fixed to the block and the inner bottom wall of the second spring groove.

[0018] A fast-assembling, tightly sealed and waterproof household laser hair removal device as described above: The sealing ring body is composed of four sealing rubber strips. An I-shaped clamping block is fixed to one end of each sealing rubber strip, and an I-shaped card slot is opened at the other end. Adjacent sealing rubber strips are assembled and connected by movably inserting the I-shaped clamping block into the I-shaped card slot inside. The eighth wedge block is fixed to the side wall of the sealing rubber strip.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: When in use, the laser head is detachably installed on the main body of the laser hair removal device, which facilitates the later maintenance of the interior of the main body of the laser hair removal device and the replacement and maintenance of the laser head. When assembling and installing the main body of the laser hair removal device and the laser head, one end of the laser head is fixed with a clamping plate, and one end of the main body of the laser hair removal device is fixed with a mounting head. The laser head and the mounting head are clamped and fixed through a clamping component. The clamping component includes a first wedge block, a first groove body, etc. After the clamping plate is inserted into the inner side of the mounting head, the first wedge block moves to the inner side of the first groove body to squeeze the second wedge block, driving the second wedge block to move upward. At the same time, the connecting plate squeezes the first spring, making the first spring in a compressed state. When the first wedge block continues to move forward and its end passes over the bottom end of the second wedge block, the elastic reset of the first spring drives the second wedge block to move downward and engage with the end of the first wedge block, realizing the quick clamping and fixing between the main body of the laser hair removal device and the laser head. A sealing ring groove is formed on the clamping plate, and a sealing ring body is embedded and clamped in the sealing ring groove. After the laser head is assembled and installed on the main body of the laser hair removal device, the sealing ring body seals the gap between the clamping plate and the laser head to prevent water leakage. Therefore, in the present invention, it is not necessary to fix with screws and install a sealing ring when assembling and installing the main body of the laser hair removal device and the laser head, and the assembly steps are fast and labor-saving;

[0020] In addition, after the main body of the laser hair removal device and the laser head are assembled and installed, an expansion component is arranged between the clamping plate and the partition plate. The expansion component includes a seventh wedge block, a card slot, etc. The sealing ring body is composed of three sealing rubber strips. Adjacent sealing rubber strips are assembled and connected by being movably inserted and clamped into the I-shaped card slot through an I-shaped card block. When the sealing ring body is inserted into the sealing ring groove, the eighth wedge block is clamped in the card slot. When the clamping plate is clamped in the laser head, the seventh wedge block is movably clamped in the card slot and cooperates with the eighth wedge block to squeeze the sealing ring body, so that the vertical sealing ring body expands outward, so that the two vertical sealing rubber strips squeeze outward to fully seal the gap between the clamping plate and the laser head, and the upper and lower sealing rubber strips generate elastic deformation when bent, store elastic potential energy and squeeze outward. Therefore, the sealing ring body of the present invention can fully fill the sealing gap between the clamping plate and the laser head, ensuring the sealing effect, and there will be no problem that the sealing effect becomes poor at the sealing gap due to aging and hardening of itself after long-term use when encountering various chemical reactions.

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0036] Please refer to Figures 1 to 13 , as an embodiment of the present invention, a household laser hair removal device with fast assembly, tight sealing and waterproofing includes a main body 1 of the laser hair removal device. One end of the main body 1 of the laser hair removal device is fixed with a mounting head 3. A laser head 2 is detachably mounted on the mounting head 3. A partition board 4 is fixed on the inner wall of the laser head 2. A clamping board 5 is fixed on one side of the laser head 2. The clamping board 5 is movably embedded and clamped inside the mounting head 3. A sealing ring groove 6 is formed on the clamping board 5. A sealing ring body 7 for sealing the gap between the clamping board 5 and the mounting head 3 is embedded and clamped on the sealing ring groove 6. The laser head 2 and the mounting head 3 are clamped and fixed through a clamping component;

[0037] An expansion component is arranged between the clamping board 5 and the partition board 4. The expansion component is used to expand the sealing ring body 7 outward after the clamping board 5 and the mounting head 3 are clamped and fixed;

[0038] A stop component is arranged between the clamping board 5 and the partition board 4. The stop component is used to block the sealing ring body 7 to prevent it from falling off the sealing ring groove 6 when the clamping board 5 and the mounting head 3 are separated.

[0039] In this embodiment, during use, the laser head 2 is detachably mounted on the laser hair removal device main body 1, so that it is convenient to perform maintenance on the inside of the laser hair removal device main body 1 and replace and maintain the laser head 2 in the later stage. When assembling and installing the laser hair removal device main body 1 and the laser head 2, one end of the laser head 2 is fixed with a clamping plate 5, and one end of the laser hair removal device main body 1 is fixed with a mounting head 3. The laser head 2 and the mounting head 3 are clamped and fixed through a clamping component, so as to achieve quick clamping and fixing between the laser hair removal device main body 1 and the laser head 2. A sealing ring groove 6 is formed on the clamping plate 5, and a sealing ring body 7 is embedded and clamped in the sealing ring groove 6. After the laser head 2 is assembled and installed on the laser hair removal device main body 1, the sealing ring body 7 seals and waterproofs the gap between the clamping plate 5 and the laser head 2. Therefore, in the present invention, when assembling and installing the laser hair removal device main body 1 and the laser head 2, there is no need to fix with screws and install a sealing ring, and the assembling steps are fast and labor-saving; in addition, after the laser hair removal device main body 1 and the laser head 2 are assembled and installed, an expansion component is arranged between the clamping plate 5 and the partition plate 4 to expand the sealing ring body 7 outwards, so that the sealing ring body 7 fully seals the gap between the clamping plate 5 and the laser head 2 by outward extrusion. Therefore, the sealing ring body 7 of the present invention can fully fill the sealing gap between the clamping plate 5 and the laser head 2; in addition, a stop component is arranged between the clamping plate 5 and the partition plate 4, and the stop component is used to block the sealing ring body 7 to prevent it from falling off the sealing ring groove 6 when the clamping plate 5 and the mounting head 3 are separated after the laser head 2 and the laser hair removal device main body 1 are disassembled and installed.

[0040] As a further scheme of the present invention, the outer dimensions of the laser head 2 and the clamping plate 5 are adapted to the inner dimensions of the mounting head 3, and the clamping plate 5 can be movably embedded and clamped inside the mounting head 3.

[0041] In this embodiment, by movably embedding and clamping the clamping plate 5 inside the mounting head 3, preliminary limit clamping and fixing between the laser head 2 and the laser hair removal device main body 1 can be achieved.

[0042] As a further scheme of the present invention, the clamping component includes a plurality of first wedge-shaped blocks 8 fixed on the laser head 2, and a first groove body 9, a second groove body 10, a first spring groove 11 and a third groove body 12 formed inside the mounting head 3. A second wedge-shaped block 13 is movably clamped in the second groove body 10. The top end of the second wedge-shaped block 13 is fixed with a third wedge-shaped block 14, and a connecting plate 15 is fixed on the second wedge-shaped block 13. A first spring 16 is arranged inside the first spring groove 11. One end of the first spring 16 is fixed to the inner top wall of the first spring groove 11, and the other end is fixed to the connecting plate 15. An extrusion component is slidably arranged in the third groove body 12, and the extrusion component is used to extrude the third wedge-shaped block 14 to lift upwards.

[0043] The extrusion assembly includes a sliding plate 19 that is snap-fitted inside the third groove 12. At both ends of the sliding plate 19, a fourth wedge block 20 and a push plate 21 are respectively fixed. A limiting assembly for the movement of the sliding plate 19 is provided inside the third groove 12. The limiting assembly is used to limit the sliding plate 19 when it moves inside the third groove 12 to prevent it from slipping out of the third groove 12.

[0044] The limiting assembly includes a fixing plate 17 fixed to the inner wall of the third groove 12. A first baffle 18 is fixed to the bottom of the fixing plate 17. A second baffle 22 is fixed to the top of the sliding plate 19. The second baffle 22 is fitted and snapped on one side of the first baffle 18 close to the third wedge block 14.

[0045] In this embodiment, when assembling and installing the laser hair removal device main body 1 and the laser head 2, a clamping plate 5 is fixed at one end of the laser head 2, and a mounting head 3 is fixed at one end of the laser hair removal device main body 1. The laser head 2 and the mounting head 3 are clamped and fixed through a clamping assembly. The clamping assembly includes a first wedge block 8, a first groove 9, etc. After the clamping plate 5 is inserted into the inner side of the mounting head 3, the first wedge block 8 moves to the inner side of the first groove 9 to squeeze the second wedge block 13, driving the second wedge block 13 to move upward. At the same time, the connecting plate 15 squeezes the first spring 16 to make the first spring 16 in a compressed state. When the end of the first wedge block 8 continues to move forward and crosses the bottom end of the second wedge block 13, the elastic reset of the first spring 16 drives the second wedge block 13 to move downward to be clamped with the end of the first wedge block 8, realizing the quick clamping and fixing between the laser hair removal device main body 1 and the laser head 2. A sealing ring groove 6 is formed on the clamping plate 5, and a sealing ring body 7 is embedded and clamped in the sealing ring groove 6. After the laser head 2 is assembled and installed on the laser hair removal device main body 1, the sealing ring body 7 seals and waterproofs the gap between the clamping plate 5 and the laser head 2. At the same time, when disassembling the laser head 2 and the laser hair removal device main body 1, manually pressing the push plate 21 will drive the sliding plate 19 to slide inside the third groove 12, driving the fourth wedge block 20 to squeeze the third wedge block 14, so as to lift one end of the third wedge block 14 upward, thereby lifting the second wedge block 13 upward, so that the bottom end of the second wedge block 13 is disengaged from the clamping and fixing with the first wedge block 8. At this time, the laser head 2 can be quickly detached from the laser hair removal device main body 1.

[0046] As a further solution of the present invention, one ends of the first groove 9 and the third groove 12 respectively penetrate through the mounting head 3 and are formed as notches on the surface of the mounting head 3.

[0047] In this embodiment, the first wedge block 8 can enter the inside of the first groove 9 through the notch, and the fourth wedge block 20 sliding inside the third groove 12 can extend to the surface of the mounting head 3 through the notch, which is convenient for manual pressing.

[0048] As a further solution of the present invention, the expansion component includes a seventh wedge block 28 fixed on the partition plate 4 and a card slot 29 opened on the clamping plate 5. The seventh wedge block 28 is movably clamped inside the card slot 29. An eighth wedge block 33 is fixed on the inner side wall of the sealing ring body 7. The eighth wedge block 33 is movably clamped inside the card slot 29 and cooperates with the seventh wedge block 28.

[0049] In this embodiment, when the sealing ring body 7 is embedded inside the sealing ring groove 6, the eighth wedge block 33 is clamped inside the card slot 29. When the clamping plate 5 is clamped inside the laser head 2, the seventh wedge block 28 is movably clamped inside the card slot 29 and cooperates with the eighth wedge block 33 to squeeze the sealing ring body 7, so that the sealing ring body 7 expands outwards, so that the sealing ring body 7 fully seals the gap between the clamping plate 5 and the laser head 2 by squeezing outwards. Therefore, the sealing ring body 7 of the present invention can fully fill the sealing gap between the clamping plate 5 and the laser head 2.

[0050] As a further solution of the present invention, the stop component includes a fifth wedge block 23 fixed on the partition plate 4 and a second spring groove 24 opened on the clamping plate 5. A clamping block 25 is movably clamped inside the second spring groove 24. The top of the clamping block 25 is fixed with a sixth wedge block 26 arranged through the clamping plate 5, and a second spring 27 is arranged at the bottom. Both ends of the second spring 27 are fixed to the clamping block 25 and the inner bottom wall of the second spring groove 24 respectively.

[0051] In this embodiment, when the clamping plate 5 is clamped inside the mounting head 3, the fifth wedge block 23 will squeeze the sixth wedge block 26, and cooperate with the compression of the second spring 27 to make the sixth wedge block 26 move downwards. When the laser hair removal instrument main body 1 is disassembled from the laser head 2, the clamping plate 5 is detached from the inside of the mounting head 3. At this time, the fifth wedge block 23 no longer squeezes the sixth wedge block 26, and the compressed second spring 27 will reset, pushing the clamping block 25 and the sixth wedge block 26 upwards. Thus, the sixth wedge block 26 can be stuck on one side of the sealing ring body 7 to limit it, preventing the sealing ring body 7 from slipping out of the sealing ring groove 6 when the clamping plate 5 is detached from the mounting head 3.

[0052] As a further solution of the present invention, the sealing ring body 7 is composed of four sealing rubber strips 30. One end of the sealing rubber strip 30 is fixed with an I-shaped clamping block 31, and the other end is provided with an I-shaped card slot 32. Adjacent sealing rubber strips 30 are assembled and connected by the I-shaped clamping block 31 being movably embedded and clamped inside the I-shaped card slot 32. The eighth wedge block 33 is fixed on the side wall of the sealing rubber strip 30.

[0053] In this embodiment, when the clamping plate 5 is clamped inside the laser head 2, the seventh wedge block 28 is movably clamped inside the card slot 29 and cooperates with the eighth wedge block 33 to squeeze the sealing ring body 7, so that the sealing ring body 7 in the vertical section expands outward, so that the two sealing rubber strips 30 in the vertical section are fully sealed to the gap between the clamping plate 5 and the laser head 2 by squeezing outward, while the sealing rubber strips 30 at the upper and lower ends generate elastic deformation when bent, store elastic potential energy and squeeze outward.

[0054] The working principle of the present invention is as follows: When in use, the laser head 2 of the present invention is detachably mounted on the laser hair removal device main body 1. The laser head 2 is used for laser hair removal. By assembling and installing the laser head 2 and the laser hair removal device main body 1, it is convenient to perform maintenance on the inside of the laser hair removal device main body 1 and replace and maintain the laser head 2 in the later stage. When assembling and installing between the laser hair removal device main body 1 and the laser head 2, a fixed clamping plate 5 is provided at one end of the laser head 2, and a fixed mounting head 3 is provided at one end of the laser hair removal device main body 1. The laser head 2 and the mounting head 3 are clamped and fixed through a clamping component. The clamping component includes a first wedge block 8, a first groove 9, etc. After the clamping plate 5 is inserted into the inner side of the mounting head 3, the first wedge block 8 moves to the inner side of the first groove 9 to squeeze the second wedge block 13, driving the second wedge block 13 to move upward. At the same time, the connecting plate 15 squeezes the first spring 16 to make the first spring 16 in a compressed state. When the end of the first wedge block 8 continues to move forward and crosses the bottom end of the second wedge block 13, the elastic reset of the first spring 16 is used to drive the second wedge block 13 to move downward and be clamped with the end of the first wedge block 8, realizing the quick clamping and fixing between the laser hair removal device main body 1 and the laser head 2. A sealing ring groove 6 is provided on the clamping plate 5, and a sealing ring main body 7 is embedded and clamped in the sealing ring groove 6. After the laser head 2 is assembled and installed on the laser hair removal device main body 1, the sealing ring main body 7 seals and waterproofs the gap between the clamping plate 5 and the laser head 2. Therefore, when assembling and installing the laser hair removal device main body 1 and the laser head 2, the present invention does not need to be fixed with screws and install a sealing ring, and the assembly steps are fast and labor-saving; in addition, after the laser hair removal device main body 1 and the laser head 2 are assembled and installed, an expansion component is provided between the clamping plate 5 and the partition plate 4. The expansion component includes a seventh wedge block 28, a clamping groove 29, etc. The sealing ring main body 7 is composed of three sealing rubber strips 30. Adjacent sealing rubber strips 30 are movably embedded and clamped inside an I-shaped clamping groove 32 through an I-shaped clamping block 31 for assembly connection. When the sealing ring main body 7 is embedded inside the sealing ring groove 6, an eighth wedge block 33 is clamped inside the clamping groove 29. When the clamping plate 5 is clamped inside the laser head 2, the seventh wedge block 28 is movably clamped inside the clamping groove 29 and cooperates with the eighth wedge block 33 to squeeze the sealing ring main body 7, so that the vertical section of the sealing ring main body 7 expands outward, so that the two sealing rubber strips 30 in the vertical section fully seal the gap between the clamping plate 5 and the laser head 2 by squeezing outward, and the sealing rubber strips 30 at the upper and lower ends generate elastic deformation when bent, store elastic potential energy and squeeze outward. Therefore, the sealing ring main body 7 of the present invention can fully fill the sealing gap between the clamping plate 5 and the laser head 2, ensuring the sealing effect and having a good tight waterproof effect.

[0055] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic features of the present invention, all technical solutions that can implement the present invention in other specific forms are included in the present invention.
