Description

Technical Field

[0001] The utility model relates to the technical field of medical cosmetic instruments, in particular to a cosmetic instrument. Background Art

[0002] With the development of economy and the improvement of people's living standards, people not only put forward new requirements for the functions of beauty instruments, but also hope that their overall appearance will be more beautiful. The overall appearance of existing handheld ultrasonic beauty instruments is too traditional and cannot meet people's needs. In order to facilitate users to use it with one hand and take into account the requirements of appearance, the designer designed the overall appearance of the portable beauty instrument into an egg shape or a pebble shape. Its characteristics are that the components are installed inside the shell and the outer surface is a smooth curved surface. Since the overall appearance of the beauty instrument is designed to be egg-shaped or pebble-shaped, the traditional arrangement of components is no longer applicable. If the components are arranged in the original way, the effect of the beauty instrument will be greatly reduced, which is not conducive to user use. Utility Model Content

[0038] The utility model mainly provides a beauty instrument, which can be a hair removal instrument, a skin rejuvenation instrument, a massage instrument, etc., taking a beauty instrument that can emit ultrasonic energy as an example.

[0039] The specific structure of the beauty instrument will be mainly described below.

[0040] Reference Figures 1 to 8 In an embodiment of the utility model, the beauty instrument comprises:

[0041] The housing 100 includes a first housing 110 and a second housing 120 which are detachably connected. The overall shape of the housing 100 is an ellipsoid. The second housing 120 has an open end 121 and a closed end 122. The open end 121 cooperates with the first housing 110. The open end 121 has a mounting opening 123. The mounting opening 123 is arranged at an angle of 25° to 45° with respect to the length direction of the housing 100.

[0042] The ultrasonic emitting device 300 is installed in the second shell 120 and is arranged close to the opening end 121. The ultrasonic emitting direction of the ultrasonic emitting device 300 and the direction of the installation opening 123 are arranged at an angle of 0° to 5°.

[0043] Specifically, in this embodiment, there are many ways to disassemble and connect the first shell 110 and the second shell 120, such as through snap connection, magnetic adsorption connection, etc., which are not particularly limited here. It is only necessary that the outer shell 100 formed by splicing the first shell 110 and the second shell 120 is ellipsoidal as a whole. It is worth noting that the overall ellipsoidal shape refers to the approximate shape of the ellipsoid, which does not necessarily have to be an absolute ellipsoid. It can have a small local (compared to the overall outer shell 100) depression or protrusion according to the actual situation of the product. Regarding the ellipsoidal shape, the outer shell 100 has a first diameter 130 extending along its length, a second diameter 150 extending along its width, and a third diameter 160 extending along its thickness; and the length of the first diameter 130 is greater than the length of the second diameter 150, and the length of the second diameter 150 is greater than the length of the third diameter 160. The beauty device has a first center plane 170 passing through the first diameter 130 and the second diameter 150 , a second center plane 180 passing through the first diameter 130 and the third diameter 160 , and a third center plane 190 passing through the second diameter 150 and the third diameter 160 .

[0044] The first shell 110 has a first inclined surface on one side facing the second shell 120, and the second shell 120 has a second inclined surface on one side facing the first shell 110. The first inclined surface and the second inclined surface have the same inclination angle, and the first inclined surface and the second inclined surface are inclined relative to the third center plane 190. There are many ways to form the installation port 123, taking cutting as an example. Regarding the orientation of the installation port 123, taking the orientation of the installation port 123 being perpendicular to the second inclined surface as an example, at this time, the angle between the installation port 123 and the length direction of the shell 100 is equal to the angle between the second inclined surface and the third center plane 190. Therefore, when the installation port 123 is cut to form, and the orientation of the installation port 123 needs to be determined, the angle between the second inclined surface formed by cutting and the third center plane 190 can be controlled. The angle α between the orientation of the installation port 123 and the length direction of the shell 100 can be 27°, 29°, 31°, 33°, 35°, 37°, 39°, 42°, etc., taking 35° as an example.

[0045] The specific forms of the ultrasonic emitting device 300 can be many, taking an ultrasonic transducer as an example. There can be many ways to install the ultrasonic emitting device 300 in the second shell 120, such as fastening connection by screws, buckles, etc., or it can be movably connected in the second shell 120, and the movably connected method can be that the ultrasonic emitting device 300 can move along the length direction of the installation port 123. The ultrasonic emitting device 300 has an ultrasonic emitting direction. When the ultrasonic emitting device 300 is installed in the second shell 120, ensure that the ultrasonic emitting direction and the direction of the installation port 123 are set at an angle of 0° to 5°. That is, the ultrasonic emitting direction can be completely consistent with the direction of the installation port 123, or there can be a small angle deviation.

[0046] In the present embodiment, for the beauty instrument having an ellipsoidal overall shape, in order to facilitate user use, the orientation of the mounting opening 123 is set to be at an angle of 25° to 45° with the length direction of the housing 100 (the inclined surface replaces the straight end surface, so that when the user uses the beauty instrument, the deflection angle of the handheld beauty instrument is greatly reduced, so that the user can use it more conveniently); on this basis, by setting the emission direction of the ultrasonic emitting device 300 to be basically consistent with the orientation of the mounting opening 123 (the deviation is less than 5°), the ultrasonic energy emitted by the ultrasonic emitting device 300 can be well emitted from the beauty instrument. Compared with the emission along the length direction of the housing 100, the technical solution of the present embodiment can greatly improve the efficiency of ultrasonic energy emission, thereby effectively improving the utilization rate of ultrasonic energy.

[0047] In some embodiments, in order to improve the convenience of the user holding the beauty instrument, the width direction of the installation port 123 is consistent with the thickness direction of the shell 100. Specifically, in this embodiment, the plane where the installation port 123 is located, or the second inclined surface, is perpendicular to the first center plane 170. The shell has a first curved surface facing the two first center planes 170 (respectively located at the two ends of the shell thickness direction), two second curved surfaces facing the second center plane 180 (respectively located at the two ends of the shell width direction), and two third curved surfaces facing the third center plane 190 (respectively located at the two ends of the shell thickness length). The installation port 123 is oriented toward the first curved surface and the third curved surface, so that the installation port 123 has a first symmetric plane along its length direction, and the first symmetric plane is coplanar with the first center plane 170. In this way, when the user holds the second shell 120, he can better perform beauty operations on the face and other parts.

[0048] In some embodiments, the orientation of the mounting opening 123 is set at an angle of 85° to 95° with the thickness direction of the shell 100. Specifically, in this embodiment, the angle between the orientation of the mounting opening 123 and the thickness direction of the shell 100 can be of many sizes, such as 85°, 87°, 90°, 92°, 95°, etc. Take 90° as an example. At this time, the straight line where the orientation of the mounting opening 123 is located is located in the first center plane 170, and the thickness direction of the shell 100 is perpendicular to the first center plane 170. In this way, the mounting opening 123 is a symmetrical structure, so that after the metal shell 100 is cut and processed, the mechanical properties of the shells on both sides are equivalent, which is conducive to improving the stability of the shell 100.

[0049] In some embodiments, in order to improve the convenience of use by the user, the beauty instrument further includes a battery 600, one end of which is located on the side of the ultrasonic emitting device 300 facing away from the mounting port 123, and the other end extends to the closed end 122. Specifically, in this embodiment, when the user uses the beauty instrument, he usually holds the portion of the second shell 120 near the closed end 122. The battery 600 is arranged in a long strip shape, and the battery 600 extends along the length direction of the shell. The weight of the battery 600 is relatively large. By arranging the heavier battery 600 at the portion near the closed end 122, the user can hold the heavier portion when holding the beauty instrument, thereby facilitating the stability of the user holding the beauty instrument. At the same time, by arranging the battery 600 to extend along the length direction of the shell 100, the weight in the shell is relatively evenly distributed, which is conducive to the user's holding.

[0050] In some embodiments, in order to further improve the weight uniformity of the handheld portion of the second housing 120, the battery 600 passes through the first center plane 170; and / or, the battery 600 passes through the second center plane 180; and / or, one end of the battery 600 close to the mounting opening 123 is arranged close to the third center plane 190. Specifically, in this embodiment, by passing the battery 600 through the first center plane 170 and the second center plane 180, the center of gravity of the battery 600 is close to the intersection of the first center plane 170 and the second center plane 180, so that the center of gravity of the battery 600 is close to the center of the width direction and the thickness direction of the second housing 120. By arranging one end of the battery 600 close to the mounting opening 123 close to the third center plane 190, most of the battery 600 is located in the portion of the second housing 120 close to the closed end 122, that is, most of the battery 600 is located in the portion held by the user, which is conducive to improving the stability of the beauty instrument held by the user.

[0051] In some embodiments, in order to further improve the convenience of user use, the two ends of the mounting opening 123 in the length direction are respectively a first end 125 and a second end 126, and the distance from the first end 125 to the closed end 122 is less than the distance from the second end 126 to the closed end 122; the battery 600 is arranged near the first end 125. Specifically, in this embodiment, when the user uses the beauty instrument, the first end 125 is usually located below the second end 126, and the battery 600 is arranged near the first end 125, that is, when the user uses the beauty instrument, the battery 600 is located below the handheld state, so that the center of the beauty instrument moves downward, which is conducive to the user's use. In some embodiments, the beauty instrument further includes a main control board 800, and the main control board 800 and the battery 600 are arranged in parallel in the width direction of the beauty instrument. In this embodiment, by arranging the main control board 800 and the battery 600 in parallel, the arrangement of the components in the second housing 120 is compact, and the space is repeatedly and reasonably utilized. At the same time, the weight of the main control board 800 is lighter than that of the battery 600, which is equivalent to moving the center of gravity downward or inward when in use, which is beneficial to the user.

[0052] In some embodiments, in order to simplify the structure, the beauty instrument also includes a driving motor 710 and a transmission assembly 720. The driving motor 710 is connected to the ultrasonic transmitting device 300 through the transmission assembly 720 so that the ultrasonic transmitting device 300 can move along the length direction of the mounting port 123; the length direction of the output shaft 711 of the driving motor 710 is set at an angle of 0° to 5° with the direction of the mounting port 123.

[0053] Specifically, in this embodiment, the transmission assembly 720 is used to convert the rotation of the driving motor 710 into the movement of the ultrasonic transmitting device 300. The transmission assembly 720 can be in many forms, such as including a driving gear, a driven gear and an eccentric structure. Specifically, a guide groove is provided in the second housing 120 along the length direction of the mounting opening, and the ultrasonic transmitting device 300 can move along the guide groove. The output shaft 711 of the driving motor 710 is connected to the driving gear, the driven gear is meshed with the driving gear, the eccentric structure and the driven gear share a rotating shaft, and the output end of the eccentric structure is connected to the ultrasonic transmitting device 300. When the driving motor 710 is working, the driving gear drives the driven gear, and the driven gear drives the eccentric structure to rotate eccentrically, so that the ultrasonic transmitting device 300 obtains the power to move, thereby moving along the guide groove. The length direction of the output shaft 711 is basically consistent with the direction of the mounting opening 123, so that there is no special angle in the power transmission process, so that a relatively simple transmission structure can realize the movement control of the ultrasonic transmitting device 300.

[0054] In some embodiments, in order to improve the utilization rate of the space inside the second housing 120, the beauty instrument further includes a battery 600, and the battery 600 and the driving device are at least partially stacked in the width direction of the housing 100. Specifically, in this embodiment, the end of the driving motor 710 away from the mounting opening 123 and the end of the battery 600 close to the mounting opening 123 are arranged side by side in the width direction of the housing 100. In this way, the internal space of the second housing 120 is fully utilized, and the heavier part is arranged toward the part held by the user when in use, which improves the compactness of the structure and is convenient for the user to hold.

[0055] In some embodiments, in order to improve the output rate of ultrasonic energy, the beauty instrument also includes an energy head shell 500, which is installed on the installation port 123, and the energy head shell 500 has an energy port 510 extending along the length direction of the installation port 123; the energy port 510 is waist-shaped, and the energy port 510 has a first symmetry plane along its length direction; the installation port 123 has a second symmetry plane along its length direction, and the distance between the first symmetry plane and the second symmetry plane is 0 to 5 mm.

[0056] Specifically, in this embodiment, the ultrasonic emitting device 300 is installed in the energy head housing 500. In some embodiments, the transmission component is also installed in the energy head housing 500, so that the energy head is an independent component, which is conducive to the assembly of the beauty instrument and improves the compactness of the structure. The first symmetry plane of the energy port 510 is perpendicular to the energy port 510, and the overall shape of the installation port 123 is elliptical, and the second symmetry plane passes through its long axis. The first symmetry plane and the second symmetry plane basically coincide with each other, and the deviation between the two is very small, so that the energy port 510 is located in the middle of the installation port 123 as much as possible. When the ultrasonic emitting device 300 emits ultrasonic energy outward, the ultrasonic energy can pass through the energy port 510 as much as possible, which is conducive to the ultrasonic energy emission of the ultrasonic emitting device 300.

[0057] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
