[0030] With the development of economy and the improvement of people's living standards, people's pursuit of beauty is also constantly improving. Medical cosmetology has become a very popular project, and more and more people who love beauty choose medical cosmetology to increase their appearance. Ultrasonic beauty instrument is a beauty instrument that focuses ultrasound on the subcutaneous fat layer to generate high heat, destroy subcutaneous fat cells, and play a fat-reducing role. The ultrasonic ring energy unit converts electrical energy into sound energy through the transducer. In order to accurately focus the sound energy emitted by the transducer, the transducer needs to be immersed in liquid, and the transducer and liquid are sealed in a closed cavity. There is a sound outlet on the cavity, and the ultrasonic wave emitted by the transducer is emitted through the sound outlet. When in use, the sound outlet is close to the skin, so that the ultrasound is focused to the receptor position. However, the wall thickness at the sound outlet is small, resulting in a low structural strength of the water tank at the sound outlet, and the sound outlet needs to frequently contact the user's face or external structure. If the structural strength is low, the water tank will be easily deformed or damaged at the ultrasonic outlet, reducing the overall structural stability of the ultrasonic beauty instrument.
[0031] The utility model provides an ultrasonic head, aiming to solve the technical problem of how to improve the structural stability of the ultrasonic head.
[0032] In the embodiment of the present utility model, Figures 1 to 3 As shown, Figure 1 This is a schematic structural diagram of an embodiment of an ultrasonic head of the utility model; Figure 2 This is a structural exploded view of an embodiment of the ultrasonic head of the utility model; Figure 3 It is a cross-sectional schematic diagram of an embodiment of the ultrasonic head of the utility model.
[0033] The ultrasonic head includes: an energy box 10, wherein the energy box 10 is provided with a receiving cavity 11, and the energy box 10 has an output wall 12, wherein the output wall 12 is provided with a sound-permeable hole 13 connected with the receiving cavity 11, and the sound-permeable hole 13 is used for ultrasonic waves to pass through; an ultrasonic transducer 20, wherein the ultrasonic transducer 20 is installed in the receiving cavity 11, wherein the ultrasonic transducer 20 is used to convert electrical energy into sound energy, and the output end of the ultrasonic transducer 20 faces the sound-permeable hole 13; a sound-permeable membrane 30, wherein the sound-permeable membrane 30 is sealed on the sound-permeable hole 13; and a reinforcement member 40, wherein the reinforcement member 40 is installed at the sound-permeable hole 13 to improve the structural strength of the energy box 10 at the sound-permeable hole 13.
[0034] In this embodiment, the overall shape of the energy box 10 can be many, such as cylindrical, pancake-shaped, etc., which are not specifically limited here, and are subject to the specific working conditions. The overall shape is roughly cylindrical as an example, and the cross-section is roughly elliptical as an example. The receiving chamber 11 is used to accommodate the ultrasonic solution and the ultrasonic transducer 20. The ultrasonic solution can provide better ultrasonic output conditions for the ultrasonic transducer 20. The energy box 10 can be an integrally formed structure, or it can be formed by a combination of multiple parts. In this embodiment, the energy box 10 includes an upper shell and a bottom cover as an example. The output wall 12 is located in the upper shell and opposite to the bottom cover, and the sound-transmitting hole 13 is opened in the upper shell. The sound-transmitting hole 13 can have many shapes, such as circular, elliptical, etc., which are not specifically limited here, and the shape similar to the cross-sectional shape of the energy box 10 is taken as an example.
[0035] The sound-transmitting membrane 30 is a thin sheet structure, which is fixedly installed at the position of the sound-transmitting hole 13, and covers the sound-transmitting hole 13 to prevent the ultrasonic solution from flowing out of the sound-transmitting hole 13. There are many ways to connect the sound-transmitting membrane 30 to the output wall 12, such as through colloid bonding or welding, etc., which are not specifically limited here, and the basis is that the sound-transmitting membrane 30 can seal the sound-transmitting hole 13. There are many forms of the sound-transmitting membrane 30, such as light-transmitting and light-impermeable, which are not specifically limited here, and the light-transmitting membrane is taken as an example. The ultrasonic transducer 20 is installed in the receiving cavity 11, and after the ultrasonic transducer 20 is powered on, it can convert electrical energy into sound energy. When the ultrasonic head is working, the ultrasonic transducer 20 is powered on to convert electrical energy into sound energy, and the generated ultrasonic wave is transmitted outward through the sound-transmitting hole 13. The ultrasonic solution can not only improve the transmission effect of the ultrasonic wave, but also play a cooling role for the ultrasonic transducer 20.
[0036] The ultrasonic wave generated by the ultrasonic transducer 20 has mechanical, warming and chemical effects on human skin. Ultrasonic waves have strong power and large energy. When acting on the face, they can make skin cells vibrate, produce a fine massage effect, change the cell volume, and thus improve the circulation of local blood and lymph, enhance the permeability of cells, improve the metabolism and regeneration capacity of tissues, soften tissues, stimulate the nervous system and cell functions, and make the skin shiny and elastic. Through the warming effect of ultrasonic waves, the temperature of the skin surface can be increased, the blood circulation can be accelerated, the nutrients of skin cells can be increased, the excitability of nerves can be reduced, the analgesic effect can be achieved, the spasmodic muscle fibers can be relaxed, and the spasmodic effect can be achieved. The heat of ultrasonic waves is endogenous heat. 79% to 82% of the heat is transported away from the action area by blood, and 18% to 21% is dispersed to the adjacent tissues by heat conduction. Therefore, the user has no obvious heat sensation. Ultrasonic waves can enhance catalytic ability, accelerate the metabolism of skin cells, change the pH value of tissues to an alkaline direction, and reduce acidosis and pain associated with skin inflammation. Ultrasound can increase the permeability of cell membranes, depolymerize nutrients and drugs, facilitate the skin to absorb nutrients, facilitate drugs to penetrate into bacteria, and improve bactericidal ability.
[0037] The structural strength and rigidity of the reinforcing member 40 are greater than those of the output wall 12, thereby supporting and reinforcing the output wall 12. When the output wall 12 abuts against the user's skin, the reinforcing member 40 can support the output arm and prevent it from being deformed and damaged due to the force.
[0038] It can be understood that the material hardness of the reinforcement 40 is greater than the material hardness of the energy box 10, so that the reinforcement 40 has higher compressive strength and deformation resistance than the energy box 10, to ensure that the reinforcement 40 effectively strengthens and supports the energy box 10.
[0039] The reinforcing member 40 can be a plastic member or a metal member. Specifically, the reinforcing member 40 is set as a stainless steel member, so that the reinforcing member 40 can be prevented from being corroded and rusted by the ultrasonic solution on the basis of ensuring the strength and rigidity of the reinforcing member 40, so as to improve the structural stability of the reinforcing member 40.
[0040] In practical applications, the thickness of the reinforcement member 40 is set to 0.2 mm to 2 mm, for example, it can be 0.2 mm, 0.4 mm, 0.6 mm, 0.8 mm, 1 mm, 1.2 mm, 1.4 mm, 1.6 mm, 1.8 mm or 2 mm, etc. The thickness of the reinforcement member 40 refers to the dimension of the reinforcement member 40 along the depth direction of the sound-permeable hole 13. If the thickness of the reinforcement member 40 is less than 0.2 mm, the reinforcing support effect on the output wall 12 is poor; if the thickness of the reinforcement member 40 is greater than 2 mm, it will occupy too much space inside the receiving cavity 11 or increase the external size of the energy box 10 too much; therefore, setting the thickness of the reinforcement member 40 to 0.2 mm to 2 mm can not only ensure the reinforcing support effect on the output wall 12, but also reasonably control the influence of the reinforcement member 40 on the internal occupied space or external size of the energy box 10.
[0041] The reinforcement member 40 may be installed on the outer wall surface of the output wall 12 or on the hole wall of the sound-transmitting hole 13 , and no limitation is made here.
[0042] For example, Figure 3 As shown, the reinforcement member 40 is installed on the inner wall surface of the output wall 12, so that the reinforcement member 40 can be hidden and protected, and the matching structure of the reinforcement member 40 and the energy box 10 can be more compact.
[0043] The reinforcement member 40 may be in a block shape, a strip shape, or a ring shape, which is not limited here.
[0044] Specifically, Figure 2 As shown, the reinforcement member 40 is disposed around the sound-transmitting hole 13 , so that the supporting area of the reinforcement member 40 on the output wall 12 can be increased to improve the supporting effect on various parts around the sound-transmitting hole 13 .
[0045] The reinforcing member 40 and the energy box 10 may be connected by snapping or bonding, which is not limited here.
[0046] For example, Figure 3 and Figure 4 As shown, Figure 4 The figure is a cross-sectional exploded view of an embodiment of the ultrasonic head of the utility model. The inner wall of the energy box 10 is provided with a snap-fitting rib 14, and a groove 15 is formed between the snap-fitting rib 14 and the output wall 12, and the reinforcing member 40 is embedded in the groove 15. The snap-fitting rib 14 can fix the reinforcing member 40 to the inner wall surface of the output wall 12. When installing the reinforcing member 40, the reinforcing member 40 can be installed into the receiving cavity 11 from the opening of the bottom wall of the upper shell, and the reinforcing member 40 can be squeezed through the snap-fitting rib 14 so that the reinforcing member 40 is inserted into the groove 15. In this way, the fixing method of the reinforcing member 40 in the energy box 10 can be simplified to improve the installation convenience of the reinforcing member 40.
[0047] The clamping rib 14 can be a block-shaped convex rib or a ring-shaped convex rib, which is not limited here.
[0048] Specifically, Figure 3 and Figure 4 As shown, the clamping rib 14 extends along the circumference of the sound-permeable hole 13. In this way, the clamping area of the clamping rib 14 to the reinforcement member 40 can be increased to improve the installation stability of the reinforcement member 40.
[0049] In practical applications, such as Figure 4 As shown, a guide slope 141 is formed on one side of the clamping rib 14 away from the output wall 12, and the guide slope 141 is used to guide the reinforcement member 40 toward the embedding groove 15. When the reinforcement member 40 is installed into the embedding groove 15, it is necessary to squeeze the clamping rib 14 to make the clamping rib 14 slightly elastically deformed, so that the reinforcement member 40 can overcome the resistance of the clamping rib 14 and then embed into the embedding groove 15. The guide slope 141 can make the compressive force of the reinforcement member 40 on the clamping rib 14 produce a component force along the width direction of the sound-transmitting hole 13, so that the clamping rib 14 can be squeezed and deformed more easily, so as to further reduce the difficulty of installing the reinforcement member 40 and improve the installation efficiency of the reinforcement member 40.
[0050] For example, Figure 3 As shown, the protruding height of the snap-in rib 14 on the inner wall of the energy box 10 is less than the width of the reinforcement 40. The width of the reinforcement 40 is the dimension of the reinforcement 40 along the protruding height direction of the snap-in rib 14. Setting the protruding height of the snap-in rib 14 to be less than the width of the reinforcement 40 can reduce the resistance caused by the snap-in rib 14 to the installation process of the reinforcement 40, thereby further reducing the installation difficulty of the reinforcement 40 and improving the installation efficiency of the reinforcement 40.
[0051] The utility model also provides an ultrasonic beauty instrument, which includes a housing and an ultrasonic head. The specific structure of the ultrasonic head refers to the above embodiments. Since the beauty instrument adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here. The ultrasonic head is installed in the housing.
[0052] In the technical solution of the ultrasonic head of the utility model, a reinforcement member 40 is installed at the sound-transmitting hole 13 of the energy box 10, which can support and strengthen the output wall 12, thereby improving the structural strength of the energy box 10 at the sound-transmitting hole 13 to prevent the energy box 10 from being easily deformed or damaged at the sound-transmitting hole 13, thereby improving the structural stability of the ultrasonic head.
