Description

Technical Field

[0001] The utility model relates to the field of beauty care, in particular to a skin treatment device. Background Art

[0002] With the development of technology, more and more beauty products such as hair removal devices, photorejuvenation devices, beauty devices, etc. are used by people.

[0003] Existing beauty devices such as hair removal devices and photon rejuvenation devices all include a shell, a light source, a filter, a fan and a light output component, etc. The light source, the filter and the light output component are all arranged in the shell. In order to facilitate ventilation and heat dissipation of related electronic components, holes are generally punched in the shell to form vents, and the vents are connected to the air inlet of the fan, so that the related electronic components in the shell can be ventilated and cooled through the suction and blowing effects of the fan.

[0004] However, the existing beauty devices such as hair removal devices and photon skin rejuvenation devices have holes in the shell to form vents, which will make the vents exposed to the outside. The disadvantages of the vents exposed to the outside are: dust and water are easy to enter the vents, which may easily cause short circuits and other faults in the internal electronic components of the existing beauty devices, shortening the life of the existing beauty devices. At the same time, the exposed air inlet holes are also easy to draw in other external silk objects, such as women's hair. Due to the suction effect of the fan, silk objects such as women's hair enter the internal electronic components of the beauty devices, which may easily cause damage to the internal structure of the beauty devices, thereby reducing the service life of the beauty devices. Furthermore, the exposed vents are easy to cause the light source generated by the beauty devices to leak, causing a certain impact on the eyes of the user. Utility Model Content

[0035] In the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0036] [First embodiment]

[0037] See also Figure 1-Figure 5 As shown, an embodiment of the utility model provides a skin treatment device 1 , and the skin treatment device 1 includes, for example: a housing 800 .

[0038] Specifically, the housing 800 is provided with a skin contact portion 820. In the skin treatment device 1 provided in the embodiment of the utility model, the skin contact portion 820 is used to contact the user's skin, and allows the light generated by the light source in the skin treatment device 1 to be emitted from the skin contact portion 820 and reach the user's skin and achieve a skin treatment effect, such as hair removal treatment, beauty whitening treatment and other skin treatment effects.

[0039] The housing 800 includes, for example, a first housing 801 and a second housing 802 . The first housing 801 and the second housing 802 are connected. In this embodiment, the first housing 801 is, for example, a lower housing, and the second housing 802 is an upper housing.

[0040] like Figure 1-Figure 3As shown, the first shell 801 is provided with a first extension portion 8011, and the first extension portion 8011 extends outward from the connection between the first shell 801 and the second shell 802. The first extension portion 8011 can extend from the connection in a direction away from the first shell 801, and the first extension portion 8011 can be parallel to the side of the second shell 802 close to the first shell 801. The first extension portion 8011 is spaced apart from the second shell 802 to form a ventilation space 806, and the second shell 802 is provided with a first vent 8021, and the first vent 8021 is connected to the ventilation space 806. Since the first extension portion 8011 can be parallel to the side of the second shell 802 close to the first shell 801, there can be a certain distance between the first extension portion 8011 and the second shell, and the distance can form a certain gap.

[0041] In the prior art, existing beauty devices such as hair removal devices and photorejuvenation devices have holes in the shell to form vents, which will make the vents exposed to the outside, and the vents exposed to the outside have certain disadvantages. The skin treatment device 1 of the present application is provided with a first extension portion 8011 extending outward from the connection between the first shell 801 and the second shell 802, so that a ventilation space 806 is formed between the first extension portion 8011 and the second shell 802. Since the extension of the first extension portion 8011 makes the ventilation space 806 in a covered state, the ventilation space 806 will not be exposed to the outside, and a hidden design of the ventilation space 806 is formed. Since the ventilation space 806 is in a covered state, the ventilation space 806 will not be easily infiltrated with dust or water. Secondly, since the ventilation space 806 is in a non-exposed state, the ventilation space 806 will not easily be entangled with silk thread items, such as women's hair, thereby not causing damage to the internal structure of the skin treatment device 1, thereby increasing the service life of the skin treatment device. Furthermore, since the ventilation space 806 is not exposed to the outside but is a hidden design, the light source generated inside the skin treatment device 1 will not leak light, and the user will not be illuminated by the light generated inside the skin treatment device on the non-skin contact part, thereby not affecting the user's sense of use and experience.

[0042] like Figure 1-Figure 5As shown, in a preferred embodiment of the present embodiment, the second shell 802 is provided with a second extension portion 8022 extending toward the first extension portion 8011 and a ventilation surface 8023 intersecting the second extension portion 8022, and the first vent 8021 is provided on the second ventilation surface 8023. The second shell 802 includes a first side 8024 and a second side 8025 opposite to the first side 8024, the ventilation surface 8023 extends from the first side 8024 to the second side 8025, and the first extension portion 8011 corresponds to the ventilation surface 8023. In the present embodiment, the second extension portion 8022 is provided on both sides of one end of the second shell 802, that is, the second extension portion can extend from one side of one end of the second shell 801 to the other side of one end. Since the first extension part 8011 needs to cover the first vent 8021 disposed on the ventilation surface 8023, the first extension part 8011 also needs to extend from the first side 8024 to the second side 8025 and correspond to the ventilation surface 8023. Thus, the hidden design of the ventilation space 806 and the first vent 8021 can be realized. Secondly, the second shell 802 is provided with a second extension part 8022, and the ventilation space 806 is formed by the enclosure between the ventilation surface 8023, the second extension part 8022 and the first extension part 8011. By providing the second extension part 8022, the airflow entering the ventilation space 806 can be guided to the first vent 8021 through the action of the second extension part 8022.

[0043] In this embodiment, if Figure 2-Figure 5 As shown, the opening size of the first vent 8021 does not exceed the height of the first extension 8011, the first vent 8021 is arranged on the vent surface 8023, and the first vent 8021 is located near the second extension 8022. By setting the opening size of the first vent 8021 to not exceed the height of the first extension 8011, the first vent 8021 will not be exposed to the outside, so that the first vent 8021 is always in the first extension 8011, and the first extension 8011 can always cover the first vent 8021, so that the first vent 8021 is also a hidden design, which improves the service life of the skin treatment device and the user experience.

[0044] Specifically, Figure 2-Figure 5As shown, the first vent 8021 includes a plurality of first through holes, which are arranged at intervals on the ventilation surface 8023 and communicate with the ventilation space 806. In other embodiments, the vent 8021 may be, for example, a long strip through hole, which extends from the first side 8024 to the second side 8025. That is, the shape of the first vent 8021 can be set according to actual conditions. For example, when the demand for air intake is not very large, the first vent 8021 can be set to a plurality of small holes arranged at intervals, or when the demand for air intake is very large, the first vent 8021 can be set to a continuous hole, which can be a long strip or an oblong, and the specific shape is not limited here.

[0045] Furthermore, if Figure 1 and Figure 3 As shown, the second housing 802 is also provided with a second vent 8026, and the second housing 802 includes a charging through hole 8027, and the second vent (8026) is arranged adjacent to the charging through hole 8027. The charging through hole 8027 can be used, for example, as a channel for charging the skin treatment device 1. The number of the second vent 8026 can be one, two, or more than two. When the second vent 8026 is one, the second vent 8026 can be arranged around the charging through hole 8027, that is, the second vent 8026 can be an arc-shaped vent. When the number of the second vent 8026 is more than two, a plurality of second vents 8026 can be distributed around the charging through hole 8027. In this embodiment, the second vent 8026 and the charging through hole 8027 are located at the bottom of the second housing 802, and the first vent 8021 is arranged on the top of the second housing 802. By arranging the second vent 8026, the air intake of the skin treatment device 1 can be increased.

[0046] Furthermore, if Figure 1 and Figure 3 As shown, the second housing 802 is further provided with a third vent 8028, the third vent 8028 being located between the first vent 8021 and the second vent 8026 and being provided on the first side 8024 and / or the second side 8025. By providing the third vent 8028, the air intake of the skin treatment device 1 can be increased.

[0047] like Figure 3As shown, in a preferred embodiment of the present embodiment, the first shell 801 and the second shell 802 are enclosed to form a receiving chamber 830, and the receiving chamber 830 is respectively connected with the first vent 8021, the second vent 8026 and the third vent 8028. The skin treatment device 1 further comprises a gas driving device 550, which is arranged in the receiving chamber 830 and is respectively connected with the first vent 8021, the second vent 8026 and the third vent 8028, and the gas driving device 550 is used to introduce the airflow flowing into the first vent 8021, the second vent 8026 and the third vent 8028 and blow it into the receiving chamber 830. The gas driving device 550 is, for example, a centrifugal fan, and the centrifugal fan is, for example, a centrifugal fan in the prior art. By providing the pneumatic drive device 550, the gas flowing into the first vent 8021, the second vent 8026 and the third vent 8028 can flow into the air inlet of the pneumatic drive device 550, and then the air is blown into the accommodating cavity 830 by the action of the pneumatic drive device 550, so that the electronic components in the accommodating cavity 830, such as the circuit board, can take away the heat emitted by the circuit board through the gas blown by the pneumatic drive device 550, thereby reducing the damage to other electronic components caused by the heat emitted by the circuit board.

[0048] like Figure 3 As shown, the skin treatment device 1 further includes, for example, a snap-fitting member 850, and the snap-fitting member 850 is respectively connected to the first housing 801 and the second housing 802. The snap-fitting member 850 includes, for example, a first snap-fitting member 851 and a second snap-fitting member 852, the first snap-fitting member 851 is arranged on the first housing 801, the second snap-fitting member 802 is arranged on the second housing 852, and the first snap-fitting member 851 is connected to the second snap-fitting member 852. In this embodiment, the first snap-fitting member 855 is, for example, a protrusion, such as a convex block or a convex strip, and the second snap-fitting member 852 is, for example, a concave portion corresponding to the protrusion, such as a groove having a size corresponding to the convex block. Of course, in other embodiments, the first engaging member 851 may be a recessed portion, and the second engaging member 852 may be a protruding portion corresponding to the recessed portion. The protruding portion may be arranged on the first housing 801 according to actual conditions, and the corresponding recessed portion may be arranged on the second housing 802; or the protruding portion may be arranged on the first housing 801, and the corresponding recessed portion may be arranged on the second housing 802, which is not specifically limited here. In addition, the connection method between the first housing 801 and the second housing 802 is not limited to the snap-fit ​​connection in this application, and may also be a fixed connection method of a screw and a nut, which may be arranged according to actual conditions, which is not specifically limited here.

[0049] [Second embodiment]

[0050] In this embodiment, the structure of the skin treatment device 1 is substantially the same as that of the skin treatment device 1 in the first embodiment, except that the first vent 8021 is located at the second extension portion 8022 .

[0051] Specifically, Figure 6-Figure 7 As shown, the first vent 8021 is arranged in the second extension part 8022, and the second extension part 8022 extends from the first side 8024 to the second side 8025. The first vent 8021 includes a plurality of first through holes, which are arranged at intervals in the second extension part 8022 and communicate with the ventilation space 806; or the vent 8021 is a long strip through hole, which extends from the first side 8024 to the second side 8025. That is, the shape of the first vent 8021 can be set according to actual conditions. For example, when the demand for air intake is not very large, the first vent 8021 can be set to a plurality of small holes arranged at intervals, or when the demand for air intake is very large, the first vent 8021 can be set to a continuous hole, which can be a long strip or an oblong, and the specific shape is not limited here.

[0052] In this embodiment, by setting the first vent 8021 on the second extension portion 8022, the first vent 8021 is always in the shielding range of the first extension portion 8011, so that the setting of the first vent 8021 is a hidden setting, so that the user will not be illuminated by the light generated inside the skin treatment device 1 on the non-skin contact part, and the first vent 8021 will not be exposed to the outside, so that the skin treatment device 1 can achieve the effect of increasing the service life, improving the aesthetics and the user's experience.

[0053] [Third embodiment]

[0054] In this embodiment, the structure of the skin treatment device 1 is substantially the same as that of the skin treatment device 1 in the first embodiment, except that the first vent 8021 extends from the vent surface 8023 to the second extension portion 8022 .

[0055] Specifically, Figure 8-Figure 9As shown, the first vent 8021 extends from the ventilation surface 8023 to the second extension 8022. The opening size of the first vent 8021 does not exceed the height of the first extension 8011. In this embodiment, the first vent 8021 can be, for example, an L-shaped vent. The first vent 8021 includes a plurality of first through holes, which are arranged at intervals on the ventilation surface 8023 and the second extension 8022 and are connected to the ventilation space 806; or the vent 8021 is a long strip through hole, which extends from the first side 8024 to the second side 8025. The shape of the first vent 8021 can be set according to actual conditions. For example, when the demand for air intake is not very large, the first vent 8021 can be set to a plurality of L-shaped small holes arranged at intervals, or when the demand for air intake is very large, the first vent 8021 can be set to a continuous L-shaped hole, which can be a long strip or an oblong, which is not limited here.

[0056] In this embodiment, the first vent 8021 is extended from the ventilation surface 8023 to the second extension portion 8022, so that the first vent 8021 is always in the shielding range of the first extension portion 8011, so that the setting of the first vent 8021 is a hidden setting. Since the first vent 8021 is in a covered state, the first vent 8021 will not be easily infiltrated with dust and water. Secondly, since the first vent 8021 is in a non-exposed state, the first vent 8021 will not be easily involved in silk thread items, such as women's hair, thereby not causing damage to the internal structure of the skin treatment device 1, thereby improving the service life of the skin treatment device. Furthermore, since the first vent 8021 is not exposed to the outside, but is a hidden design, the light source generated inside the skin treatment device 1 will not cause light leakage, and the user will not be illuminated by the light generated inside the skin treatment device on the non-skin contact part, thereby not affecting the user's sense of use and experience.

Under the premise that the technical features do not conflict, the structures do not contradict, and the purpose of the present invention is not violated, the technical solutions of the various embodiments can be arbitrarily combined and used in combination.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
