Description

Technical Field

[0001] The invention relates to the field of beauty instruments, and in particular to an ultrasonic skin scraping machine. Background Art

[0002] Ultrasonic skin scrapers can clean the skin and are popular among consumers. When using them, wet the skin with water or skin care products, and bring the blade of the ultrasonic skin scraper into direct contact with the skin. The blade produces high-frequency oscillations, which can discharge some grease and impurities. At the same time, the water medium produces a large number of tiny bubbles under the influence of ultrasonic energy. The impact caused by the bursting of the bubbles under pressure can also help enhance the cleaning effect.

[0003] The scraping blade of the current ultrasonic skin scraping machine is fixedly connected to the main machine. For example, Chinese utility model patent No. 201921896496.X proposes an ultrasonic skin scraping machine, wherein the ultrasonic blade (281) is fixedly connected to the working end (2), the ultrasonic blade (281) is vertically arranged relative to the working end (2), the angle between the ultrasonic blade (281) and the working end (2) is fixed, and the ultrasonic blade (281) cannot be rotated relative to the working end (2) to adjust the angle. In particular, when the user needs to clean the back skin, the ultrasonic blade (281) vertically arranged relative to the working end (2) is not easy to reach the back skin, resulting in difficulty for the user to use.

[0031] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0032] Please refer to Figures 1 to 9The present invention proposes an ultrasonic skin scraper, which includes a bottom shell 10, a surface shell 20, a rotating part 30 and a scraping blade 40. The bottom shell 10 and the surface shell 20 are buckled together to form a storage cavity (not marked in the figure). The surface shell 20 is provided with a through groove 21 connected to the storage cavity. The rotating part 30 is movably accommodated in the storage cavity. The scraping blade 40 includes a scraper 41 and a mounting plate 42 fixedly connected to the scraper 41. The mounting plate 42 is installed in the rotating part 30. The scraper 41 passes through the through groove 21 and extends out of the surface shell 20. Rotating the rotating part 30 can drive the scraper 41 to rotate relative to the surface shell 20.

[0033] In the present embodiment, the scraper 41 and the mounting plate 42 are integrally formed, the mounting plate 42 is fixedly mounted in the rotating part 30, the scraper 41 passes through the rotating part 30, the scraper 41 passes through the through groove 21 and extends out of the surface shell 20; the rotating part 30 is movably accommodated in the storage cavity, the rotating part 30 can rotate relative to the bottom shell 10 and the surface shell 20, the rotating part 30 can rotate in the storage cavity, and rotating the rotating part 30 can drive the scraper 41 to rotate relative to the surface shell 20, thereby adjusting the angle of the scraper 41 relative to the surface shell 20, and the user can adjust the angle of the scraper 41 relative to the surface shell 20 according to actual use requirements, thereby facilitating user use.

[0034] Furthermore, a first positioning column 11 is provided in the bottom shell 10 , a second positioning column 31 is provided on the rotating portion 30 , a first positioning hole 12 is provided on the first positioning column 11 , and the second positioning column 31 is movably received in the first positioning hole 12 .

[0035] In this embodiment, the second positioning column 31 is movably received in the first positioning hole 12 so that the rotating portion 30 is movably connected to the bottom shell 10 , thereby enabling the rotating portion 30 to rotate relative to the bottom shell 10 .

[0036] Furthermore, the ultrasonic skin scraper also includes a limit ring 60, which is sleeved on the outside of the second positioning column 31. The limit ring 60 is located in the first positioning hole 12 and eliminates the gap between the second positioning column 31 and the inner wall of the first positioning hole 12.

[0037] In this embodiment, the limiting ring 60 is a silicone ring, which is located in the first positioning hole 12 and eliminates the gap between the second positioning column 31 and the inner wall of the first positioning hole 12, so that the damping of the rotating part 30 is greater when it rotates relative to the bottom shell 10, thereby enabling the rotating part 30 to rotate to any angle and remain stationary.

[0038] In this embodiment, the limiting ring 60 is a silicone ring, and the limiting ring 60 has a vibration reduction effect. When the rotating part 30 vibrates, the second positioning column 31 vibrates along with the rotating part 30, and the vibration transmitted to the first positioning column 11 is reduced through the limiting ring 60, thereby reducing the vibration of the bottom shell 10 and the surface shell 20.

[0039] Furthermore, the rotating part 30 is also provided with a third positioning column 32, and the surface shell 20 is also provided with a positioning plate 22 accommodated in the through groove 21, and the positioning plate 22 is provided with a second positioning hole 23, and the third positioning column 32 is inserted into the second positioning hole 23 and movably connected with the second positioning hole 23.

[0040] In this embodiment, the third positioning column 32 is inserted into the second positioning hole 23 and movably connected to the second positioning hole 23, so that the rotating part 30 is movably connected to the positioning plate 22, and the rotating part 30 can rotate equivalent to the face shell 20.

[0041] Furthermore, the ultrasonic skin scraper also includes a rotating member 70 , which is movably received in the through groove 21 , and the rotating member 70 extends into the second positioning hole 23 to form a fixed connection with the third positioning column 32 .

[0042] In this embodiment, the rotating member 70 extends into the second positioning hole 23 to form a fixed connection with the third positioning column 32, and the rotating part 30 can be driven to rotate by rotating the rotating member 70; the third positioning column 32 and the first positioning column 11 are on the same straight line, and the rotating part 30 can be driven to rotate by rotating the rotating member 70 more labor-saving.

[0043] Furthermore, a limiting column 71 is disposed on the rotating member 70 , and a limiting hole 33 matching with the limiting column 71 is disposed on the third positioning column 32 , and the limiting column 71 is inserted into the limiting hole 33 .

[0044] In this embodiment, the cross-sectional shape of the limiting column 71 is non-circular, and the third positioning column 32 is provided with a limiting hole 33 matching the limiting column 71. The limiting column 71 is inserted into the limiting hole 33, and the third positioning column 32 cannot rotate in the limiting hole 33. The rotating member 70 is rotated to drive the rotating part 30 to rotate through the third positioning column 32.

[0045] Furthermore, the rotating member 70 is further provided with a first hook 72 , and the rotating portion 30 is further provided with a second hook 34 . The second hook 34 extends into the through slot 21 , and the second hook 34 is engaged with the first hook 72 .

[0046] In this embodiment, the second hook 34 is engaged with the first hook 72 to form a fixed connection between the rotating member 70 and the rotating portion 30 .

[0047] Furthermore, the rotating member 70 is provided with a limiting portion 73 , and the limiting portion 73 is provided with a plurality of anti-slip protrusions 74 . When the rotating member 70 rotates until the limiting portion 73 abuts against the inner wall of the through slot 21 , the rotating member 70 cannot rotate in the same direction.

[0048] In this embodiment, the friction coefficient of the limiting portion 73 is increased by means of the plurality of anti-slip protrusions 74; when the rotating member 70 is rotated until the limiting portion 73 abuts against the inner wall of the through groove 21, the rotating member 70 cannot rotate in the same direction, and the rotation angle of the scraper 41 is limited by the abutment between the limiting portion 73 and the inner wall of the through groove 21.

[0049] Furthermore, the rotating part 30 is located between the surface shell 20 and the bottom shell 10 , and a first support plate 13 is also provided in the bottom shell 10 , and the first support plate 13 abuts against the rotating part 30 . A second support plate 24 is provided in the surface shell 20 , and the second support plate 24 abuts against the rotating part 30 .

[0050] In this embodiment, the first support plate 13 reduces the contact area between the rotating part 30 and the bottom shell 10, thereby reducing the friction between the rotating part 30 and the bottom shell 10; the second support plate 24 reduces the contact area between the rotating part 30 and the surface shell 20, thereby reducing the friction between the rotating part 30 and the surface shell 20.

[0051] In this embodiment, the first support plate 13 and the second support plate 24 clamp the rotating portion 30 so that the rotating portion 30 cannot shake in the receiving cavity.

[0052] Furthermore, the ultrasonic skin scraper also includes a waterproof component 80, which is fixedly installed in the rotating part 30. The waterproof component 80 forms a seamless connection with the rotating part 30, and the waterproof component 80 forms an unconnected first cavity 36 and a second cavity 37 inside the rotating part 30. The scraper 41 is partially accommodated in the first cavity 36, and the mounting plate 42 passes through the waterproof component 80 and extends into the second cavity 37.

[0053] In this embodiment, the waterproof part 80 is made of silicone material and is elastic; the scraper 41 is partially accommodated in the first cavity 36, and the scraper 41 first extends from the first cavity 36 to the outside of the rotating part 30, and then the scraper 41 passes through the through groove 21 and extends out of the surface shell 20.

[0054] Furthermore, the ultrasonic skin scraper also includes two piezoelectric sheets 90, a circuit board 100 and a vibration sheet 110 accommodated in the second cavity 37, the mounting plate 42 is clamped between the two piezoelectric sheets 90, the circuit board 100 is fixedly stacked on the piezoelectric sheets 90, and the vibration sheet 110 is fixedly mounted on the circuit board 100.

[0055] In this embodiment, the vibration plate 110 is electrically connected to the circuit board 100, the piezoelectric plate 90 is a ceramic piezoelectric plate, the mounting plate 42 is clamped between the two piezoelectric plates 90, and the three are in a planar fitting relationship to form a seamless connection, which is beneficial for the transmission of ultrasonic energy to the scraper 41. The vibration plate 110 is an ultrasonic transducer plate for generating ultrasonic vibrations. The vibration of the vibration plate 110 causes the piezoelectric plate 90 to vibrate, and the vibration of the piezoelectric plate 90 causes the scraper blade 40 to vibrate. The vibration of the scraper blade 40 will cause the rotating part 30 to vibrate.

[0056] In this embodiment, the two piezoelectric sheets 90, the circuit board 100 and the vibration sheet 110 are all accommodated in the second cavity 37, and external liquid cannot enter the second cavity 37 through the waterproof component 80, thereby ensuring that the piezoelectric sheets 90, the circuit board 100 and the vibration sheet 110 are not damaged by external liquid; even if the user uses the ultrasonic skin scraper with skin care water, the skin care water can only enter the first cavity 36 along the scraper 41, and external liquid cannot enter the second cavity 37 through the waterproof component 80.

[0057] Furthermore, the waterproof component 80 is provided with a through hole 81 connected to the second cavity 37, and the through hole 81 is also provided with a limiting protrusion 82 fixedly connected to the waterproof component 80. The mounting plate 42 passes through the through hole 81 and extends into the second cavity 37. The limiting protrusion 82 abuts against the mounting plate 42 to form a seamless connection.

[0058] In this embodiment, the limiting protrusion 82 is integrally formed with the waterproof component 80 , and the limiting protrusion 82 abuts against the mounting plate 42 to form a seamless connection, thereby preventing external liquid from entering the second cavity 37 through the through hole 81 .

[0059] Furthermore, blocks 43 are provided on both sides of the mounting plate 42 , a slot 35 communicating with the second cavity 37 is provided in the rotating portion 30 , and the blocks 43 are engaged with the slot 35 .
