Description

Technical Field

[0001] The utility model relates to the technical field related to beauty instruments, and in particular to a portable beauty instrument with a sealing structure. Background Art

[0002] A portable beauty instrument is a portable beauty tool that uses physical technology to care for the skin to achieve a variety of beauty effects.

[0003] Portable beauty devices can deeply cleanse the skin, effectively removing dirt and oil through microcurrent or ultrasonic technology, leaving skin cleaner and fresher. They also have the ability to whiten and reduce dark spots, using specific wavelengths of photons or radio frequency technology to inhibit melanin production and reduce dark spots.

[0004] However, existing portable beauty devices, especially those that use sapphire as the contact piece between the ice compress and human skin, often produce condensation on the side of the sapphire close to the lamp tube due to the alternating effects of hot and cold, which adheres to the bottom surface of the sapphire, affecting the light output effect. In severe cases, the condensation may even flow into the main unit, causing a short circuit risk to the beauty device.

[0005] To prevent condensation on the bottom surface of sapphire, several solutions have been proposed. For example, Shenzhen Yangwo Electronics Co., Ltd. has developed a portable hair removal device (publication number: CN210872022U). This device features a hollow spacer positioned between the light-emitting portion and the light-transmitting crystal. This spacer seals the area between the light-emitting portion and the light-transmitting crystal, preventing liquefaction of gas on opposite sides of the filter and / or light-transmitting crystal, further improving light output quality. It also prevents liquid from leaking out, protecting internal electronic components.

[0006] The above-mentioned prior art solves the problem of preventing condensation from forming on the bottom surface of the sapphire to a certain extent. However, when using a portable beauty instrument, it is often necessary to apply a specific liquid, such as aloe vera gel, to the skin and then apply a cold compress through the head of the portable beauty instrument. This may cause some liquid to flow into the body through the open end of the beauty instrument head. Especially for those beauty instruments with electronic components located near the front end of the body, the entering liquid will first affect the function of the electronic components located at the open end, which will affect the normal use of the beauty instrument and even cause a short circuit risk. At the same time, if the user turns on the beauty instrument and does not use it for a long time, the external hot air will also generate condensation when it encounters the front surface of the sapphire, and the condensation will also flow into the body through the open end of the beauty instrument head. Therefore, it can be seen that preventing external liquid or condensation from entering the body through the open end of the beauty instrument head to further improve the sealing performance of portable beauty instruments is also a technical problem that needs to be paid attention to and urgently solved in this field.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are for the purpose of describing specific embodiments only and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] Please refer to Figure 1-3 The present invention provides a portable beauty instrument with a sealed structure, comprising a main body 1, wherein a receiving cavity is formed in the main body 1, and the receiving cavity is surrounded by a front cover 13, a surface cover and a bottom shell; a light emitting part and a cold compress part are accommodated in the receiving cavity;

[0029] The cold compress part includes a transparent crystal 3, an upper crystal bracket 5 and a lower crystal bracket 6. A first sealing ring 2 is provided on the upper part of the transparent crystal 3 near the surface cover 13 and is sleeved around the transparent crystal 3.

[0030] The first sealing ring 2 is arranged on the upper part of the light-transmitting crystal 3 near the opening end of the beauty instrument to prevent external liquid from penetrating into the interior of the main body through the opening end of the beauty instrument along the light-transmitting crystal, causing functional failure of electronic components near the opening end of the beauty instrument, and even affecting the function of the entire beauty instrument. In severe cases, it may cause a short circuit failure of the beauty instrument.

[0031] For example, the portable beauty instrument for which protection is sought in this application has an inductive FPC sensor 4 provided near the opening end, and the inductive FPC sensor 4 is electrically connected to the circuit board inside the host. If a first sealing ring structure is not provided, after the external liquid enters the opening end, it will first affect the functional realization of the inductive FPC sensor 4. If the entering liquid is not cleaned in time, it will further cause a short circuit failure of the circuit board.

[0032] Of course, the accommodating cavity is also provided with a cooling module, a control circuit board and other related structures that enable the normal operation of the beauty instrument. These structures do not belong to the protection focus of this application and will not be described in detail here.

[0033] In another specific embodiment, the first sealing ring 2 is located between the crystal upper support 5 and the cover 13. By providing the first sealing ring 2 between the crystal upper support 5 and the cover 13, it is possible to promptly seal the liquid entering the opening end from the outside, thereby reducing the possibility of the external liquid further penetrating into the main body along the transparent crystal.

[0034] In another specific embodiment, an annular step for accommodating the first sealing ring 2 is provided on the lower portion of the cover 13 and / or the upper portion of the crystal upper support 5. The provision of the annular step facilitates the installation of the first sealing ring.

[0035] In another specific embodiment, the upper portion of the crystal upper support 5 is provided with an annular step for accommodating the first sealing ring 2. The lower portion of the cover 13 is provided with an annular protrusion corresponding to the annular step, which presses the first sealing ring 2 against the annular step. The annular protrusion provided on the lower portion of the cover 13 compresses the first sealing ring, causing it to deform appropriately, allowing it to fit tightly against the light-transmitting crystal, thereby improving the sealing effect.

[0036] In another specific embodiment, a first groove for accommodating the first sealing ring 2 is provided on the inner side of one end of the crystal upper bracket 5 close to the surface cover 13 .

[0037] In another specific embodiment, a circle of concave structure is provided on the upper portion of the light-transmitting crystal 3 at a position corresponding to the first groove, and the first sealing ring 2 is accommodated in the space formed by the first groove and the concave structure.

[0038] By providing a concave structure on the inner side of the crystal upper bracket 5 and / or the outer side of the upper part of the transparent crystal 3, while facilitating the positioning and installation of the first sealing ring 2, the first sealing ring 2 can also be squeezed between the crystal upper bracket 5 and the transparent crystal 3, thereby improving the sealing effect.

[0039] In another specific embodiment, the light output portion includes a lamp 10, a filter 8, and a filter silicone sleeve 7. The filter silicone sleeve 7 is located between the filter 8 and the light-transmitting crystal 3 and is used to seal the area between the light-transmitting crystal 3 and the light output portion. The filter 8 is mounted on the filter bracket 9. Reflective aluminum 11 is provided on the back of the lamp. The reflective aluminum 11 reflects light emitted by the lamp 10, passes through the filter 8, and is incident on the light-transmitting crystal 3, where it is then emitted. The reflective aluminum 11 is mounted on the reflective aluminum bracket 12.

[0040] The installation method of the filter bracket 9, the lamp tube 10, the reflective aluminum 11 and the reflective aluminum bracket 12 belongs to the conventional installation method in this field and will not be described in detail here.

[0041] In another specific embodiment, the filter silicone sleeve 7 has a hollow groove structure, and the groove structure is arranged facing the bottom of the transparent crystal 3, and a sealed hollow isolation space is formed between the groove structure and the bottom of the transparent crystal 3.

[0042] Providing a hollow spacer between the light-transmitting crystal 3 and the light-emitting portion belongs to the prior art, but by coordinating the hollow spacer with the first sealing ring 2 , the sealing effect of the beauty instrument can be improved as a whole.

[0043] In another specific embodiment, a second sealing ring (not shown in the figure) is provided around the light-transmitting crystal 3 on one side of the lower portion of the light-transmitting crystal 3 close to the filter silicone sleeve 7 .

[0044] In another specific embodiment, a second groove for accommodating the second sealing ring is provided on the inner side of one end of the crystal lower bracket 6 close to the filter silicone sleeve 7 and / or on the outer side of the lower part of the transparent crystal 3.

[0045] The setting of the second sealing ring can further cooperate with the hollow isolation piece to achieve vacuum isolation between the light-transmitting crystal 3 and the light-emitting part. At the same time, it can also play the role of a second layer of sealing, that is, when the first sealing ring 2 is aged and damaged and loses its sealing function, it can prevent external liquid from further penetrating into the interior of the main body.

[0046] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
