Abstract
Description
Technical Field
[0001] This utility model relates to an ultrasonic beauty device, and more particularly to an ultrasonic beauty head. Background Technology
[0002] Existing ultrasonic beauty devices usually require replacing the ultrasonic beauty head with a different type of ultrasonic beauty head to change the treatment depth. Frequent replacement of ultrasonic beauty heads has the following disadvantages: (1) It is not only cumbersome to operate, increasing the difficulty and time cost for users, but also easily leads to damage or loss of the ultrasonic beauty head; (2) There are installation errors in the ultrasonic beauty head, and the treatment depth will deviate after replacement. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide an adjustable ultrasonic beauty head, which can quickly switch the treatment depth without the need to change different types of ultrasonic beauty heads.
[0004] To solve the above-mentioned technical problems, this utility model provides an adjustable ultrasonic beauty head, including a transducer and an ultrasonic membrane located in front of the transducer. The transducer generates ultrasonic waves through mechanical vibration, and the ultrasonic waves are transmitted forward to the skin surface by the ultrasonic membrane. A spring applies a backward elastic force to the transducer. A cam and a toggle key for operation are provided behind the transducer. When the cam is turned forward by the toggle key, it pushes the transducer to move closer to the ultrasonic membrane, thus overcoming the spring force. When turned in the opposite direction, it releases the pushing force on the transducer, thus moving it away from the ultrasonic membrane under the spring force.
[0005] Furthermore, the toggle key is provided with a forward toggle part and a reverse toggle part, and the cam is provided with a receiving part that extends radially between the forward toggle part and the reverse toggle part. It receives the forward toggle from the forward toggle part to drive the cam to rotate in the forward direction, and receives the reverse toggle from the reverse toggle part to drive the cam to rotate in the reverse direction.
[0006] Furthermore, the toggle button includes a transmission component located inside the beauty head, with a forward toggle part and a reverse toggle part specifically provided on the transmission component.
[0007] Furthermore, the toggle switch has multiple positions, with different positions corresponding to different angles at which the cam is rotated, and corresponding to different distances at which the transducer is actuated and de-actuated.
[0008] Furthermore, the toggle key has multiple toggle positions, with different positions corresponding to different angles of rotation of the cam, which correspond to different distances of pushing and releasing the transducer. When the toggle key is moved to a toggle position and stops, the cam stops between the forward and reverse toggle sections.
[0009] Furthermore, the toggle button includes a transmission component located inside the beauty head. The transmission component is equipped with a buckle, and the beauty head is equipped with multiple positioning holes. The buckle engages with different positioning holes, and the toggle button accordingly achieves different toggle positions.
[0010] Furthermore, the spring is specifically a tension spring.
[0011] Furthermore, the transducer extends rearward with a push rod, and the cam pushes the transducer specifically by pushing the push rod 1, with a spring sleeved on the push rod.
[0012] This invention provides an adjustable ultrasonic beauty head. By using a toggle switch to rotate the cam, the distance between the transducer and the ultrasonic membrane can be adjusted, thus changing the treatment depth of the ultrasonic beauty head. This eliminates the need to change different types of ultrasonic beauty heads, reducing the difficulty of operation for users and eliminating the need for multiple beauty heads. Furthermore, by moving the toggle switch back and forth by different distances, different treatment depths can be precisely obtained without changing the beauty head, thus eliminating concerns about installation errors when changing beauty heads.

[0022] The present invention will be further described in detail below with reference to specific embodiments.
[0023] Ultrasonic beauty head Figure 1 As shown, it includes a handle 2 and an ultrasonic probe 1 vertically mounted on the handle 2, according to... Figure 2 The placement orientation shown corresponds to the forward and backward direction of handle 2. Figure 2 The left and right directions are the same, while the front and back directions of the ultrasound probe 1 correspond to the up and down directions. The rear end of the handle 2 is provided with an interface 26 for electrical connection to the ultrasound beauty instrument. The ultrasound probe 1 has an inner cavity 14, in which a transducer 11 that can mechanically vibrate to generate ultrasound waves is provided. An ultrasound membrane 12 is attached to the head end of the ultrasound probe 1 to cover the inner cavity 14. The ultrasound membrane 12 is located in front of the transducer 11 and can transmit the ultrasound waves generated by the transducer 11 to the skin surface. The inner cavity 14 is filled with a conductive fluid 3 that can conduct ultrasound waves to the ultrasound membrane 12.
[0024] like Figure 2 As shown, a push rod 111 extends rearward from the transducer 11 inside the ultrasound probe 1. A tension spring 13 is fitted onto the push rod 111. The front end of the tension spring 13 is connected to the rear end face of the transducer 11 body, and the rear end is connected to the housing of this ultrasound beauty head, applying a rearward elastic force to the transducer 11. Behind the push rod 111 is a handle 2. A cam 24 is provided in the handle 2 to drive the push rod 111 and move the transducer 11 forward inside the ultrasound probe 1, closer to the ultrasound diaphragm 12. The cam 24 is as follows... Figure 8 As shown, a rotating shaft 242 extends axially, and is installed into the housing of the ultrasonic beauty head via the rotating shaft 242. Figure 1 As shown, a slot 22 is formed on the upper surface of the handle 2, and the toggle key 21 is installed in the slot 22. Figure 2 As shown, the toggle key 21 includes a transmission component 23. The toggle key 21 moves back and forth along the toggle groove 22 on the handle 2, which in turn drives the cam 24 to rotate in both directions around the rotating shaft 242 via the transmission component 23 (described in detail below). The cam 24 rotates in the forward direction (…). Figure 2 (In the counterclockwise direction) it pushes the transducer 11 to overcome the elastic force of the tension spring 13 and move it forward within the ultrasonic probe 1, and rotates it in the opposite direction ( Figure 2 Turning clockwise releases the push on the transducer 11, causing it to move backward within the ultrasonic probe 1 under the elastic force of the tension spring 13. Specifically, a mechanism is provided between the toggle key 21 and the cam 24 as shown in the image. Figure 5 The transmission component 23 shown has a fixing hole 231 on its upper surface, and the toggle key 21 is as follows: Figure 3 As shown, a fixing pin 211 is provided on the lower surface. The fixing pin 211 is inserted downward into the fixing hole 231 to achieve fixation. The transmission component 23 is as follows. Figure 6 As shown, a toggle part 235 extends from its lower surface, and a cam 24 is as follows. Figure 4As shown, a receiving portion 241 extends radially accordingly, and the receiving portion 241 is as follows: Figure 6 As shown, it extends radially from below the transmission member 23 to between the rear and front parts of the actuating portion 235. (As indicated...) Figure 2 As shown, when the toggle key 21 is moved forward, the rear part of the toggle part 235 of the transmission member 23 acts as the forward toggle part 233, which moves the forward-moving part 241 of the cam 24, causing the cam 24 to rotate forward around the axis 242. When the toggle key 21 is moved backward, the front part of the toggle part 235 of the transmission member 23 acts as the reverse toggle part 234, which moves the backward-moving part 241 of the cam 24, causing the cam 24 to rotate backward around the axis 242.
[0025] In handle 2, transmission component 23 is as follows Figure 5 The upper surface shown has two round-headed latches 232, and a return spring (not shown in the figure) is located below the round-headed latches 232. The round-headed latches 232 move downward when pressed. The upper half of the handle 2 housing is as follows. Figure 7 As shown, the lower surface of the device has two rows of positioning holes 25 for the round-headed buckles 232 to engage with, with four positioning holes 25 in each row. Moving the toggle key 21 moves the transmission component 23, and each of the two round-headed buckles 232 on the upper surface of the transmission component 23 engages with one row of positioning holes 25, thus giving the toggle key 21 four toggle positions. During the process of the toggle key 21 rotating the cam 24, when the toggle key 21 is moved to a toggle position, the transmission component 23 stops by engaging the round-headed buckles 232 with the positioning holes 25. Therefore, the cam 24 between the forward toggle part 233 and the reverse toggle part 234 stops, and since the cam 24 does not rotate, the transducer 11 does not move back and forth, maintaining a constant distance from the ultrasonic diaphragm 12. When the toggle key 21 is toggled to different positions, the cam 24 is rotated to different angles, correspondingly pushing and releasing the transducer 11 by different distances, thereby switching the distance between the transducer 11 and the ultrasonic membrane 12.
[0026] The above description is merely an embodiment of the present invention and does not limit the scope of patent protection. Any non-substantial changes or substitutions made by those skilled in the art based on the present invention will still fall within the scope of patent protection.
