Description

Technical Field

[0001] The utility model relates to the technical field of hair removal devices, in particular to a hair removal device using sapphire. Background Art

[0002] As people's living standards continue to improve, they pay more and more attention to their own image and temperament. With the rapid advancement of science and technology, various beauty devices have emerged. For example, photothermal hair removal is performed on the human body through a hair removal device. Photothermal hair removal technology is a non-invasive modern hair removal technology that can safely, quickly and efficiently remove excess hair from the body.

[0003] When the hair removal device is removing hair from the human body, the quartz lamp and the condenser outside the quartz lamp will instantly generate high-energy heat. Therefore, the hair removal device needs to have strong heat dissipation performance. Otherwise, the local high temperature of the hair removal device will cause the machine to melt, causing damage to the machine and posing a risk to safety in use. In order to avoid the effects caused by high temperatures, sapphire is used in the hair removal device, and a cooling component is set for the sapphire to achieve the effect of freezing point hair removal. However, during use, there is a gap between the filter and the sapphire. This will cause water vapor to enter between the sapphire and the filter. When the water vapor encounters the sapphire with a lower temperature, it liquefies on the surface of the sapphire, thereby changing the propagation path of light and reducing the efficiency of hair removal. Utility Model Content

[0004] In order to avoid and overcome the technical problems existing in the prior art, the utility model provides a hair removal device using sapphire. The utility model can eliminate the gap between the sapphire and the filter, thereby improving the hair removal efficiency.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A hair removal device using sapphire comprises a shell, a light source is arranged inside the shell, a filter and a sapphire lens are arranged in sequence along the propagation direction of the light, and the filter and the sapphire lens are precisely fitted to each other.

[0007] As a further solution of the utility model: the housing comprises an upper shell and a lower shell with the same structure, and the upper shell and the lower shell are combined to form a mounting cavity for mounting the filter and the sapphire lens.

[0008] As a further solution of the utility model: a mounting groove is provided on the lower shell, and the filter and the sapphire lens are arranged in the mounting groove.

[0009] As a further solution of the utility model: the filter and the sapphire lens are bonded to each other by glue.

[0010] As a further solution of the utility model: the shell is made of plastic.

[0011] As a further solution of the utility model: a wedge block is arranged inside the lower shell body, and the wedge surface of the wedge block is inclined toward the sapphire lens; a slot that can be engaged with the wedge block is opened at the bottom of the filter, and the wedge block is engaged in the slot, and the wedge surface and the bottom of the slot fit each other, so that the filter tends to move toward the sapphire lens.

[0012] As a further solution of the utility model: two wedge-shaped blocks are arranged in sequence along the length direction of the filter, and two card slots are provided at corresponding positions on the filter.

[0013] As a further solution of the utility model: the interior of the upper shell is also arranged with two groups of wedge-shaped blocks which are the same as those in the interior of the lower shell, and two card slots are provided at corresponding positions on the top surface of the filter.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model uses glue to bond the sapphire and the filter together, which can eliminate the gap between the filter and the sapphire, prevent water vapor from entering between the sapphire and the filter, and thus ensure that the propagation path of light remains unchanged, thereby improving the efficiency of hair removal.

[0016] 2. The optical filter of the utility model is tightly pressed on the sapphire lens under the pushing action of the wedge-shaped block, thereby eliminating the matching gap between the two. In addition, the wedge-shaped blocks arranged symmetrically in pairs can provide four supporting and pushing points for the optical filter, so that the optical filter is evenly stressed and the tightness of the matching between the optical filter and the sapphire lens is improved.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1 to Figure 3 In an embodiment of the utility model, a hair removal device using sapphire includes a plastic housing 10, wherein the housing 10 includes an upper housing 11 and a lower housing 12 of the same structure, wherein the upper housing 11 and the lower housing 12 are matched to form a mounting cavity for mounting a filter 30 and a sapphire lens 20. The upper housing 11 and the lower housing 12 are buckled and fixed together using an inner buckle structure commonly used in the prior art.

[0025] The filter 30 and the sapphire lens 20 are installed in the installation groove, and the filter 30 and the sapphire lens 20 are arranged in sequence along the propagation direction of the light. The filter 30 and the sapphire lens 20 are closely attached to each other, and the filter 30 and the sapphire lens 20 are bonded to each other by glue. The glue used is the glue commonly used in the prior art.

[0026] In order to make the filter 30 and the sapphire lens 20 fit more stably and tightly, a wedge block 14 is arranged inside the lower housing 12. The wedge surface of the wedge block 14 is inclined toward the sapphire lens 20, and a slot 31 that can be engaged with the wedge block 14 is provided at the bottom of the filter 30. The wedge block 14 is engaged in the slot 31, and the wedge surface and the bottom of the slot 31 fit each other, so that the filter 30 has a tendency to move toward the sapphire lens 20. Two wedge blocks 14 are arranged in sequence along the length direction of the filter 30, and two slots 31 are provided at corresponding positions on the filter 30. The upper housing 11 is also arranged with two groups of wedge blocks 14 that are the same as those inside the lower housing 12, and two slots 31 are provided at corresponding positions on the top surface of the filter 30. When in use, first place the filter 30 in the lower shell 12, and make the slot 31 engage with the wedge block 14, then drip glue into the joint between the filter 30 and the sapphire lens 20, or do not drip any glue, and then cover the upper shell 11. At this time, the filter 30 is pushed by the wedge block 14 and is tightly pressed on the sapphire lens 20, thereby eliminating the fitting gap between the two.
