Description

Technical Field

[0001] This utility model relates to the field of skin care, and in particular to a matrix ultrasonic transducer. Background Technology

[0002] Ultrasonic transducers emit ultrasonic waves, which, when applied to the skin, can improve skin texture and maintain a relatively long-lasting skincare effect. Ultrasonic transducers primarily utilize the inverse piezoelectric effect to generate ultrasonic waves; that is, applying an alternating voltage to the ultrasonic head causes it to vibrate mechanically, producing and emitting ultrasonic waves. Traditional ultrasonic transducers typically feature a single, large ultrasonic head (19mm in radius). In practical applications, this single large ultrasonic head emits high-energy ultrasonic waves, and the area of ​​the ultrasonic waves acting on the skin surface to be treated is very small. This can easily lead to pitting and unevenness on the skin surface due to overly concentrated ultrasonic energy. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a matrix ultrasonic transducer that emits ultrasonic energy that is evenly dispersed and acts on a large area of ​​the skin surface to be treated, thereby avoiding excessive energy concentration and thus preventing pitting on the skin surface to be treated.

[0004] To solve the above problems, the present invention provides a matrix ultrasonic transducer, which includes multiple ultrasonic heads arranged horizontally at intervals.

[0005] Furthermore, the device includes a housing and a support frame. The support frame has a top seat and a base. Specifically, the top seat of the support frame has a flange extending outward from the top, which supports the top of the housing. The base of the support frame is located in the inner cavity of the housing, and an ultrasonic head cover is glued to its bottom surface. Multiple ultrasonic head mounting holes are opened on the bottom surface of the ultrasonic head cover, and multiple ultrasonic heads are aligned and glued into the multiple ultrasonic head mounting holes.

[0006] Furthermore, a connector and a first circuit board are provided. A placement slot is opened on the top seat of the support frame. The first circuit board is installed and fixed in the placement slot on the top seat of the support frame. The connector is installed on the first circuit board for connecting to an external power source. The inside of the support frame is a hollow structure for wires to pass through. The connector provides alternating voltage to the ultrasonic head through the wires passing through the inside of the support frame.

[0007] Furthermore, a second circuit board is attached to the inside of the outer cover of the ultrasonic head, above the ultrasonic head. The ultrasonic head is electrically connected to the second circuit board, and the wires passing through the support frame are stacked and pressed on the upper surface of the second circuit board.

[0008] Furthermore, the inner cavity of the shell is filled with degassed pure water as the ultrasonic transmission medium and the heat dissipation medium for the ultrasonic head.

[0009] Furthermore, a waterproof and sound-permeable membrane is adhered to the bottom surface of the shell.

[0010] Furthermore, a sealing ring is provided between the outer wall of the support frame top seat and the inner wall of the top of the housing to prevent the degassed pure water from leaking out.

[0011] Furthermore, there are 7 ultrasonic heads with a radius of 10mm, and 7 ultrasonic head mounting holes are correspondingly opened on the bottom surface of the ultrasonic head cover.

[0012] Beneficial effects: The matrix ultrasonic transducer of this utility model replaces a single large ultrasonic head with multiple small ultrasonic heads. The multiple ultrasonic heads are arranged horizontally and side by side. Each small ultrasonic head has lower energy. These ultrasonic heads work simultaneously, dispersing the energy that was originally concentrated at one point to a larger area. This avoids the energy of a single ultrasonic head acting on the skin surface to be treated being too concentrated, thus avoiding pitting on the skin surface to be treated.

Detailed Implementation

[0018] The present invention will be further described in detail below with reference to specific embodiments.

[0019] Matrix ultrasonic transducers such as Figure 1 As shown, it includes a housing 1 and an upper cover plate 3. (See...) Figure 2 The transducer contains a support frame 6. A flange 611 extends outward from the top of the support frame top seat 61, supporting the top of the housing 1. A screw passes through the side wall of the top of the housing 1 and is screwed into the support frame top seat 61, thus fixing the support frame 6 and the housing 1 together. (See...) Figure 3 The support base 62 is located in the inner cavity 11 of the housing. The bottom surface of the support base 62 is glued with the ultrasonic head cover 4. The bottom surface of the ultrasonic head cover 4 has 7 ultrasonic head mounting holes 41 (combined with...). Figure 2), 7 ultrasonic heads with a radius of 10mm 2 (combined with Figure 2 The connectors 7 are horizontally spaced and glued side-by-side into the seven ultrasonic head mounting holes 41. After the connectors 7 are installed on the first circuit board 10, the first circuit board 10, together with the connectors 7, is fixed with screws into the placement slots 612 on the support frame top seat 61. The top cover 3 is attached to the upper surface of the support frame top seat 61 by screws.

[0020] See Figure 3 The support frame 6 is a hollow structure, through which wires pass. A second circuit board 5 is attached above the ultrasonic head 2 inside the outer cover 4 of the ultrasonic head. The ultrasonic head 2 is electrically connected to the second circuit board 5, and the wires passing through the support frame 6 are stacked and pressed onto the upper surface of the second circuit board 5. After the connector 7 is connected to an external power source, it provides alternating voltage to the ultrasonic head 2 via wires (not shown in the attached diagram) passing through the support frame 6, causing the ultrasonic head 2 to vibrate mechanically and generate ultrasonic waves. The inner cavity 11 of the housing contains degassed purified water as the ultrasonic wave transmission medium. The ultrasonic waves generated by the mechanical vibration of the ultrasonic head 2 are transmitted through the degassed purified water in the inner cavity 11 of the housing, and emitted through the waterproof and acoustically permeable membrane 8 attached to the bottom surface of the housing 1 to the area below the transducer, acting on the skin surface to be treated below the transducer for skin care. The degassed purified water also serves as a heat dissipation medium for the ultrasonic head 2. A sealing ring 9 is fitted on the outer wall of the support frame top seat 61 to prevent degassed purified water from leaking out between the outer wall of the support frame top seat 61 and the inner wall of the top of the housing 1. Since there are 7 ultrasound heads 2 in this embodiment and the radius is only 10mm, each ultrasound head 2 in this embodiment has lower energy than a traditional single large ultrasound head. These ultrasound heads 2 work at the same time, dispersing the energy that was originally concentrated at one point to a larger area, avoiding the energy of a single large ultrasound head acting on the skin surface to be treated too concentrated, thus avoiding pitting on the skin surface to be treated.

[0021] 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.
