Description

Technical Field

[0001] The utility model relates to the field of ultrasonic technology, in particular to an ultrasonic massage device. Background Art

[0002] Massagers are electronic devices designed to relieve neck muscle tension and pain. There are many different types of traditional massagers, including vibration massage, electric heat massage, low-frequency electrical stimulation massage, and air pressure massage.

[0003] However, the massage effect of traditional massagers is not good. For example, massagers equipped with electrodes use electrical stimulation to cause muscle contraction to assist muscle training, and the massage effect is limited. Pressing massagers use various human hand-like structures to press the muscles underneath through the human body, and it is difficult to massage deep muscles. To improve the massage effect on the muscles, you can only choose to increase the pressing force, which can easily cause epidermal damage and pain, and the noise is relatively loud when working, which greatly affects the user experience.

[0004] BACKGROUND OF THE PRESENT APPLICATION The above information disclosed is only used to understand the background of the concept of the present application, and does not indicate or imply that it contains information of the prior art. Utility Model Content

[0005] Based on this, it is necessary to provide an ultrasonic massage device to address the above problems.

[0006] An ultrasonic massage device, comprising:

[0007] A shell, wherein the shell has a massage portion, and a mounting hole is formed through a shell wall of the massage portion;

[0008] A power supply component, the power supply component is arranged in the shell;

[0009] A control circuit board, the control circuit board is arranged in the housing and is electrically connected to the power supply component;

[0010] An ultrasonic transducer, the ultrasonic transducer is electrically connected to the control circuit board, the ultrasonic transducer comprises a stacked acoustic emission unit and a matching layer, the matching layer is embedded in the mounting hole, and a side of the matching layer facing away from the acoustic emission unit is exposed through the mounting hole for contact with a target tissue of a human body, the acoustic emission unit is capable of generating ultrasonic waves and transmitting the ultrasonic waves to the target tissue through the matching layer.

[0011] The above-mentioned ultrasonic massage device can at least achieve the following beneficial effects: the sound emission unit of the ultrasonic transducer can be made of a piezoelectric effect, a magnetostrictive effect, or a capacitive ultrasonic emission module or material, which can realize the conversion of electrical energy into sound energy under different conditions to generate ultrasonic waves. These ultrasonic energies are then transmitted to the skin and deep subcutaneous soft tissues through the matching layer in the mounting hole of the massage part, which can provide a deep massage effect to deep-seated muscles and other target tissues, promote blood circulation, relieve muscle tension and pain, accelerate metabolism, and help tissue repair, and the entire working process is basically noiseless.

[0012] In one embodiment, the hole wall of the mounting hole and the matching layer are sealed with a sealant. The sealing between the hole wall of the mounting hole and the matching layer can prevent foreign matter such as moisture and dust from the outside from entering the housing through the gap between the hole wall of the mounting hole and the matching layer, so as to protect various electronic components including the control circuit board in the housing.

[0013] In one embodiment, the acoustic impedance of the matching layer is between the acoustic impedance of the acoustic emitting unit and the acoustic impedance of the target tissue. It should be noted that the acoustic impedance of the ultrasonic transducer is usually quite different from the acoustic impedance of human tissue. If there is no matching layer, when the ultrasonic wave is directly transmitted from the ultrasonic transducer to the human tissue, a large part of the sound wave will be reflected back to the transducer, thereby reducing the energy entering the human tissue and affecting the depth and intensity of the ultrasonic wave under the human epidermis.

[0014] In one embodiment, the inner contour of the cross section of the mounting hole is smaller than the outer contour of the cross section of the sound emission unit, so as to limit the axial movement of the sound emission unit in the mounting hole. It is understandable that the user may accidentally drop the ultrasonic massage device during use; and the setting of this embodiment can be considered that the mounting hole is smaller than the sound emission unit, that is, the mounting hole is set to a shape and size that the sound emission unit cannot enter or pass through, thereby firmly maintaining the sound emission unit inside the shell and preventing the sound emission unit from escaping from the mounting hole.

[0015] In one embodiment, the hole wall of the mounting hole extends inward to form a limiting portion, and the limiting portion abuts against the sound emitting unit to limit the movement of the sound emitting unit in the axial direction of the mounting hole. The limiting portion can intercept the sound emitting unit inside the shell to prevent the sound emitting unit from escaping from the mounting hole.

[0016] In one embodiment, the side of the matching layer facing away from the sound emission unit at least partially protrudes from the outer surface of the massage part. Such a structural arrangement can be regarded as at least part of the matching layer extending from the mounting hole to the outside, and when the massage part contacts the human skin, it can ensure that the matching layer can be closely attached to the human skin, thereby ensuring the transmission effect of the ultrasonic wave.

[0017] In one of the embodiments, the shell includes an upper shell and a lower shell connected to the upper shell, the lower shell has the massage part, the upper shell and the lower shell are enclosed to form a chamber for loading the power supply component, the control circuit board and the ultrasonic transducer, a limiting groove is formed in the lower shell, the ultrasonic transducer is arranged in the limiting groove, and the ultrasonic transducer is fitted with the bottom of the limiting groove, and the bottom of the limiting groove is the massage part. During assembly, the power supply component, the control circuit board and the ultrasonic transducer can be placed between the upper shell and the lower shell first, and then the upper shell and the lower shell are fixed by a detachable connection or a fixed connection such as snap-on, bonding, ultrasonic welding, etc. The limiting groove in the lower shell can limit the movement of the ultrasonic transducer.

[0018] In one of the embodiments, the groove wall of the limiting groove also protrudes to form a limiting rib, and the limiting rib abuts against the periphery of the ultrasonic transducer to limit the movement of the ultrasonic transducer in the limiting groove. It can be understood that the ultrasonic transducer needs to be kept in close contact with the shell wall of the massage part of the shell, and the relative position of the two must be sufficiently reliable and stable. If the position between the ultrasonic transducer and the shell wall is offset or there is a gap between the two, this will easily affect the conduction effect of the ultrasonic wave. For example, when using the ultrasonic massage device, the user may lose control of the ultrasonic massage device, causing it to fall. The fall and collision will easily cause the ultrasonic transducer in the shell to shift due to vibration. For this reason, limiting ribs are added to the groove wall of the limiting groove in this embodiment. The limiting ribs can abut against the periphery of the ultrasonic transducer to limit the movement of the ultrasonic transducer in the limiting groove, thereby improving the connection reliability of the ultrasonic transducer.

[0019] In one embodiment, a guiding slope is provided on the side of the limiting rib facing away from the bottom of the limiting groove, and the guiding slope is used to contact the ultrasonic transducer during assembly to guide the ultrasonic transducer to slide to the bottom of the limiting groove. During assembly, the ultrasonic transducer needs to be placed in the limiting groove. If the guiding slope is not provided, the ultrasonic transducer needs to be completely aligned with the limiting groove and avoid the limiting rib before it can be placed in the limiting groove. During automated assembly, it is easy to get stuck due to errors, and the efficiency of manual assembly is also low. In this embodiment, a guiding slope is added on the side of the limiting rib facing away from the bottom of the limiting groove. The guiding slope can guide the loading of the ultrasonic transducer. Even if the ultrasonic transducer is not completely aligned with the limiting groove and avoids the limiting rib during assembly, the ultrasonic transducer hits the guiding slope during the loading process, and can still slide into the bottom of the limiting groove under the guidance of the guiding slope, which reduces the positioning accuracy requirements during assembly. Both automatic assembly and manual assembly of automated equipment are easier, which is conducive to improving assembly efficiency.

[0020] In one embodiment, the number of the limiting ribs is set to be multiple, and the multiple limiting ribs are arranged at intervals around the circumference of the ultrasonic transducer. The multiple limiting ribs can abut against the ultrasonic transducer at multiple angles in the circumferential direction, and the limiting effect is better.

[0021] In one embodiment, the ultrasonic massage device further comprises an adhesive, through which the ultrasonic transducer is attached to the bottom of the limiting groove. The adhesive may include but is not limited to adhesive.

[0022] In one embodiment, a massage convex end is formed on a side of the lower shell facing away from the upper shell, and the end surface of the massage convex end is the massage part. The user can directly press the massage convex end on the human body epidermis, and the massage convex end can make the force more concentrated. A slight press can make the skin surface concave here, so that the skin and the massage part of the end surface of the massage convex end are in close contact, which is conducive to better and deeper transmission of ultrasound to the soft tissue under the skin.

[0023] In one of the embodiments, the ultrasonic massage device further includes a conductive member, the control circuit board, the power supply assembly and the ultrasonic transducer are sequentially stacked, the ultrasonic transducer is electrically connected to the control circuit board via the conductive member, and a plurality of fixed protrusions are also protruded from the lower shell, and the plurality of fixed protrusions are arranged at intervals around the periphery of the power supply assembly to limit the movement of the power supply assembly. It can be understood that the power supply assembly is located between the control circuit board and the ultrasonic transducer, and one end of the conductive member is connected to the ultrasonic transducer, and the other end of the conductive member needs to bypass the power supply assembly to be connected to the control circuit board. If the power supply assembly moves, it will pull the conductive member or even tear the conductive member apart. In this embodiment, a plurality of fixed protrusions are arranged around the power supply assembly, which can limit the movement of the power supply assembly and avoid the above situation.

[0024] In one embodiment, the connection between the upper shell and the lower shell is sealed. For example, the connection between the upper shell and the lower shell is sealed with a sealant, or the upper shell and the lower shell are directly welded into one body to achieve a sealing effect.

[0025] In one embodiment, a side of the upper housing away from the lower housing is an elastic pressing portion, and the elastic pressing portion is configured to be deformable under external force to abut against a key on the control circuit board. The material of the elastic pressing portion may include but is not limited to silicone.

[0026] In one embodiment, the power supply component is a battery, which can directly power the ultrasonic transducer without the need for an external conductor and plug to electrically connect the ultrasonic massage device to a socket in the external environment for power supply.

[0027] In one embodiment, the ultrasonic transducer further comprises a backing layer, which is stacked with the sound emitting unit and arranged on a side of the sound emitting unit facing away from the matching layer. The backing layer can absorb ultrasonic waves emitted backwards, suppress back reflection of sound waves, and help control the vibration of the transducer. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0040] See also Figures 1 to 8 In some embodiments, the present application provides an ultrasonic massage device 10, which includes a housing 100, a power supply assembly 200, a control circuit board 300, and an ultrasonic transducer 400. The housing 100 has a massage portion 141, and a mounting hole 121 is formed through the housing wall of the massage portion 141; the power supply assembly 200 is disposed in the housing 100; the control circuit board 300 is disposed in the housing 100 and is electrically connected to the power supply assembly 200. Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the ultrasonic transducer 400 includes a stacked acoustic emission unit 420 and a matching layer 430, the matching layer 430 is embedded in the mounting hole 121, and the side of the matching layer 430 facing away from the acoustic emission unit 420 is exposed through the mounting hole 121 for contacting with the target tissue of the human body, and the acoustic emission unit 420 can generate ultrasonic waves and transmit the ultrasonic waves to the target tissue through the matching layer 430.

[0041] The above-mentioned ultrasonic massage device 10 can at least achieve the following beneficial effects: the sound emission unit 420 of the ultrasonic transducer 400 can be made of a piezoelectric effect, a magnetostrictive effect, or a capacitive ultrasonic emission module or material, which can realize the conversion of electrical energy into acoustic energy under different conditions to generate ultrasonic waves, which are then transmitted to the skin and deep subcutaneous soft tissues through the matching layer 430 in the mounting hole 121 of the massage part 141, and can provide a deep massage effect to target tissues such as deep muscles, promote blood circulation, relieve muscle tension and pain, accelerate metabolism, and help tissue repair, and the entire working process is basically noiseless.

[0042] Furthermore, in some embodiments, a sealant is used to seal the hole wall of the mounting hole 121 and the matching layer 430. The sealing between the hole wall of the mounting hole 121 and the matching layer 430 can prevent foreign matter such as moisture and dust from the outside from entering the housing 100 through the gap between the hole wall of the mounting hole 121 and the matching layer 430, so as to protect various electronic components including the control circuit board 300 in the housing 100.

[0043] Furthermore, in some embodiments, the acoustic impedance of the matching layer 430 is between the acoustic impedance of the acoustic emitting unit 420 and the acoustic impedance of the target tissue. It should be noted that the acoustic impedance of the ultrasonic transducer 400 is usually quite different from the acoustic impedance of human tissue. If there is no matching layer 430, when the ultrasonic wave is directly transmitted from the ultrasonic transducer 400 to the human tissue, a large part of the sound wave will be reflected back to the transducer, thereby reducing the energy entering the human tissue and affecting the depth and intensity of the ultrasonic wave under the human epidermis.

[0044] See also Figure 4 and Figure 5 In some embodiments, the inner contour of the cross section of the mounting hole 121 is smaller than the outer contour of the cross section of the sound emission unit 420, so as to limit the axial movement of the sound emission unit 420 in the mounting hole 121. It is understandable that the user may accidentally drop the ultrasonic massage device 10 during use; and the setting of this embodiment can be considered that the mounting hole 121 is smaller than the sound emission unit 420, that is, the mounting hole 121 is set to a shape and size that the sound emission unit 420 cannot enter or pass through, thereby firmly maintaining the sound emission unit 420 inside the housing 100 and preventing the sound emission unit 420 from escaping from the mounting hole 121.

[0045] See also Figure 4 and Figure 5In some embodiments, the hole wall of the mounting hole 121 extends inward to form a limiting portion, and the limiting portion abuts against the sound emitting unit 420 to limit the movement of the sound emitting unit 420 in the axial direction of the mounting hole 121. The limiting portion can intercept the sound emitting unit 420 inside the housing 100 to prevent the sound emitting unit 420 from escaping from the mounting hole 121.

[0046] See also Figure 5 In some embodiments, the side of the matching layer 430 facing away from the sound emission unit 420 at least partially protrudes from the outer surface of the massage part 141. Such a structural setting can be regarded as at least part of the matching layer 430 extending from the mounting hole 121 to the outside, and when the massage part 141 contacts the human skin, it can ensure that the matching layer 430 can be closely attached to the human epidermis, thereby ensuring the transmission effect of the ultrasonic wave.

[0047] See also Figure 1 and Figure 6 In some embodiments, the housing 100 includes an upper housing 110 and a lower housing 120 connected to the upper housing 110, the lower housing 120 has the massage part 141, and the upper housing 110 and the lower housing 120 enclose a chamber for loading the power supply assembly 200, the control circuit board 300 and the ultrasonic transducer 400. During assembly, the power supply assembly 200, the control circuit board 300 and the ultrasonic transducer 400 can be first placed between the upper housing 110 and the lower housing 120, and then the upper housing 110 and the lower housing 120 are fixed to each other by a detachable connection or a fixed connection such as a snap connection, a bonding connection, or an ultrasonic welding connection.

[0048] Specifically, Figures 2 to 7 As shown, in some embodiments, a limiting groove 130 is formed in the lower housing 120, the ultrasonic transducer 400 is disposed in the limiting groove 130, and the ultrasonic transducer 400 is in contact with the bottom of the limiting groove 130, and the bottom of the limiting groove 130 is the massage part 141. The limiting groove 130 can limit the movement of the ultrasonic transducer 400.

[0049] More specifically, if Figures 2 to 7As shown, in some embodiments, a limiting rib 131 is protruded from the groove wall of the limiting groove 130 , and the limiting rib 131 abuts against the periphery of the ultrasonic transducer 400 to limit the movement of the ultrasonic transducer 400 in the limiting groove 130 . It is understandable that the ultrasonic transducer 400 needs to be kept in close contact with the shell wall of the massage part 141 of the shell 100, and the relative position of the two must be sufficiently reliable and stable. If the position between the ultrasonic transducer 400 and the shell wall is offset or there is a gap between the two, this will easily affect the conduction effect of the ultrasonic wave. For example, the user may slip out of his hands during the use of the ultrasonic massage device 10, causing the ultrasonic massage device 10 to fall. The fall and collision will easily cause the ultrasonic transducer 400 in the shell 100 to shift due to vibration. For this reason, a limiting rib 131 is additionally provided on the groove wall of the limiting groove 130 in this embodiment. The limiting rib 131 can abut the periphery of the ultrasonic transducer 400 to limit the movement of the ultrasonic transducer 400 in the limiting groove 130, thereby improving the connection reliability of the ultrasonic transducer 400.

[0050] More specifically, if Figures 2 to 5 As shown, in some embodiments, a guide slope 1311 is provided on the side of the limiting rib 131 facing away from the bottom of the limiting groove 130, and the guide slope 1311 is used to contact the ultrasonic transducer 400 during assembly to guide the ultrasonic transducer 400 to slide toward the bottom of the limiting groove 130. During assembly, the ultrasonic transducer 400 needs to be placed in the limiting groove 130. If the guide slope 1311 is not provided, the ultrasonic transducer 400 needs to be completely aligned with the limiting groove 130 and avoid the limiting rib 131 before it can be placed in the limiting groove 130. The machine is easily stuck due to errors during automated assembly, and the efficiency of manual assembly is also low. In this embodiment, a guiding slope 1311 is added to the side of the limiting rib 131 facing away from the bottom of the limiting groove 130. The guiding slope 1311 can guide the installation of the ultrasonic transducer 400. Even if the ultrasonic transducer 400 is not completely aligned with the limiting groove 130 and avoids the limiting rib 131 during assembly, and hits the guiding slope 1311 during the installation process of the ultrasonic transducer 400, it can still slide into the bottom of the limiting groove 130 under the guidance of the guiding slope 1311, thereby reducing the positioning accuracy requirement during assembly. Both automatic assembly by automated equipment and manual assembly are easier, which is conducive to improving assembly efficiency.

[0051] More specifically, if Figure 7 As shown, in some embodiments, the number of the limiting ribs 131 is set to be multiple, and the multiple limiting ribs 131 are arranged at intervals around the periphery of the ultrasonic transducer 400. The multiple limiting ribs 131 can abut against the ultrasonic transducer 400 at multiple angles in the circumferential direction, and the limiting effect is better.

[0052] More specifically, in some embodiments, the power supply assembly 200 is a battery, which can directly power the ultrasonic transducer 400 without the need for an external conductor and plug to electrically connect the ultrasonic massage device 10 to a socket in the external environment for power supply.

[0053] More specifically, in some embodiments, the connection between the upper shell 110 and the lower shell 120 is sealed. For example, the connection between the upper shell 110 and the lower shell 120 is sealed with a sealant, or the upper shell 110 and the lower shell 120 are directly welded into one body to achieve a sealing effect.

[0054] More specifically, in some embodiments, the ultrasonic massage device 10 further includes an adhesive (not shown), through which the ultrasonic transducer 400 is attached to the bottom of the limiting groove 130. The adhesive may include but is not limited to adhesive.

[0055] See also Figure 2 In some embodiments, the lower housing 120 is formed with a massage convex end 140 on one side facing away from the upper housing 110, and the end surface of the massage convex end 140 is the massage part 141. The user can directly press the massage convex end 140 on the human body epidermis, and the massage convex end 140 can make the force more concentrated. A slight press can make the skin surface concave here, so that the skin and the massage part 141 on the end surface of the massage convex end 140 are in close contact, which is conducive to better and deeper transmission of ultrasound to the soft tissue under the skin.

[0056] Please refer to the figure Figure 6 In some embodiments, the ultrasonic massage device 10 further includes a conductive member 500, the control circuit board 300, the power supply assembly 200 and the ultrasonic transducer 400 are sequentially stacked, the ultrasonic transducer 400 is electrically connected to the control circuit board 300 through the conductive member 500, and a plurality of fixing protrusions 180 are protrudingly formed in the lower shell 120, and the plurality of fixing protrusions 180 are spaced around the periphery of the power supply assembly 200 to limit the movement of the power supply assembly 200. It can be understood that the power supply component 200 is located between the control circuit board 300 and the ultrasonic transducer 400, and one end of the conductive member 500 is connected to the ultrasonic transducer 400, and the other end of the conductive member 500 needs to bypass the power supply component 200 to be connected to the control circuit board 300. If the power supply component 200 moves, the conductive member 500 will be pulled or even torn off. In this embodiment, a plurality of fixed protrusions 180 are arranged around the power supply component 200, which can limit the movement of the power supply component 200 and avoid the occurrence of the above situation.

[0057] See also Figure 1 and Figure 2In some embodiments, the side of the upper housing 110 away from the lower housing 120 is an elastic pressing portion 111, and the elastic pressing portion 111 is configured to be deformed under external force to abut against the button 310 on the control circuit board 300. The material of the elastic pressing portion 111 may include but is not limited to silicone, and various marks may be set on the surface to remind the user of the functions of different pressing positions, such as increasing or decreasing ultrasonic waves, or switching massage modes, etc.

[0058] See also Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 8 In some embodiments, the ultrasonic transducer 400 further includes a backing layer 410, which is stacked with the sound emitting unit 420, and the backing layer 410 is disposed on a side of the sound emitting unit 420 that is away from the matching layer 430. The backing layer 410 can absorb ultrasonic waves emitted backward, suppress back reflection of sound waves, and help control the vibration of the transducer.
