Description

Technical Field

[0001] The embodiments of the present disclosure relate to, but are not limited to, the field of ultrasound, and in particular, to an ultrasound therapy device. Background Art

[0002] Ultrasonic massage therapy has been widely used in physical therapy and cosmetic treatments due to its effectiveness in promoting blood circulation, relieving muscle tension, and enhancing drug absorption. To overcome the drawbacks of static ultrasound applications, which can lead to localized heat accumulation and insufficient mechanical action, related technologies have proposed devices equipped with rotatable ultrasonic transducers. A motor drives the transducer head to rotate unidirectionally (in a fixed direction) around its axis, enhancing the transducer's dynamic range of tissue stimulation and the depth of the massage effect.

[0003] However, this unidirectional rotational ultrasonic massage mode presents other problems. When performing continuous treatment on the same surface treatment area for extended periods, this unidirectional rotational mechanism can significantly increase the risk of damage to the skin and subcutaneous tissue. The fundamental reason is that continuous unidirectional rotation can lead to multiple adverse cumulative effects. For example, unidirectional friction and traction continuously act on the skin surface. Especially when treatment intensity is high or duration is prolonged, the epidermal stratum corneum is more susceptible to damage due to excessive unidirectional friction.

[0004] Therefore, in scenarios where long-term or high-intensity treatment is required, the inherent unidirectional continuous action characteristics of unidirectional rotating ultrasonic massagers have obvious safety defects. Utility Model Content

[0014] In some embodiments, the identification sensor is disposed on an end of the boss close to the ultrasonic component through the first circuit board.

[0015] In some embodiments, the ultrasonic assembly includes a mounting member and an ultrasonic transducer and an inner ring tooth respectively located on both sides of the mounting member, and the inner ring tooth is located in a groove formed between the outer peripheral wall of the boss and the inner peripheral wall of the mounting groove.

[0040] In order to effectively solve the risk of friction damage caused by long-time single-area one-way continuous rotation of the one-way rotating ultrasonic massage instrument, the utility model provides an ultrasonic physiotherapy equipment 10. Referring to Figure 1 And Figure 6 The ultrasonic physiotherapy equipment 10 includes a shell 100, an ultrasonic assembly 200 and a control piece. The ultrasonic assembly 200 includes an ultrasonic transducer 220 capable of emitting ultrasonic waves, so that the ultrasonic physiotherapy equipment 10 works by using the thermal effect, mechanical effect and cavitation effect of ultrasonic waves. Among them, the thermal effect can improve the tissue temperature, promote blood circulation and metabolism, and effectively relieve pain and muscle spasm. The mechanical effect can drive the movement of intracellular substances, enhance the permeability of cell membrane, and thus improve the cell function. The cavitation effect generates microbubbles, which form a fine massage on the tissue, promote drug absorption and inflammation dissipation. Therefore, the ultrasonic physiotherapy equipment 10 in the embodiment can be applied to the auxiliary treatment (promote absorption and relieve pain) of chronic pelvic inflammation, adnexitis and other gynecological inflammation, as well as the treatment of gastrointestinal dysfunction, intestinal adhesion and other digestive system diseases (improve peristalsis and relieve abdominal distension and abdominal pain).

[0041] In order to better explain the embodiment, the following is described in a combined manner with the drawings, and it should be noted that the structure in the drawings is only illustrative and does not specifically limit the structure in the embodiment, and other structures derived therefrom are also within the protection scope of the utility model.

[0042] Referring to Figures 1 to 6The ultrasonic assembly 200 of the ultrasonic therapy device 10 is rotatably connected to the housing 100, enabling rotational motion relative to the housing 100. To enable automatic reciprocating rotation of the ultrasonic assembly 200 within a predetermined angular range, the ultrasonic therapy device 10 includes an identification sensor and an identification element 410. Specifically, one of the ultrasonic assembly 200 and the housing 100 is provided with an identification sensor, and the other is provided with at least one identification element 410, with the identification sensor and the identification element 410 being spatially opposed. Optionally, the ultrasonic therapy device 10 may include two, three, or four identification elements 410. For example, the ultrasonic assembly 200 may be provided with an identification sensor, and the housing 100 may be provided with at least one identification element 410; alternatively, the ultrasonic assembly 200 may be provided with at least one identification element 410, and the housing 100 may be provided with an identification sensor. This is not a specific limitation and can be arranged according to the internal space of the ultrasonic therapy device 10. It should be noted that the identification sensor and the identification element 410 need to be positioned relative to each other. The ultrasonic assembly 200 rotates relative to the housing 100, causing the relative position between the identification sensor and the object to be identified 410 to change. The identification sensor and the object to be identified 410 are configured so that when the ultrasonic assembly 200 rotates to a predetermined position, the object to be identified 410 triggers the identification sensor, causing the identification sensor to output a reversal trigger signal. A control unit is connected to the identification sensor and is configured to control the ultrasonic assembly 200 to rotate in the opposite direction upon receipt of the reversal trigger signal.

[0043] When the ultrasonic component 200 reaches a preset position during forward rotation (triggering the identification sensor), it rotates in the reverse direction; when it reaches the same or different preset position during reverse rotation (triggering the identification sensor again), it rotates in the reverse direction again (i.e., returns to the forward direction), and so on and so forth, thereby achieving automatic, continuous, periodic alternating forward and reverse rotation (i.e., reciprocating rotation) of the ultrasonic component 200 within a predetermined angle. The predetermined angle range here is determined by the preset position, and its specific value can be set according to actual usage, for example, within a range of 0° to 90°, or 120°. It should be noted that the size of the predetermined angle determines the range of the ultrasonic therapy device's active area. The smaller the predetermined angle, the more concentrated the active area of ​​the ultrasonic therapy device 10.

[0044] This embodiment utilizes a recognition sensor that works in conjunction with the object to be recognized. Upon detecting that the ultrasonic component has moved to a preset position, the recognition sensor automatically generates a reversal trigger signal. In response to this signal, the control unit controls the reverse rotation of the ultrasonic component, causing it to reciprocate within a predetermined angle range. Compared to the unidirectional, continuous rotation mode of devices in related technologies, the ultrasonic component of this utility model automatically reverses direction upon reaching a preset angle, significantly reducing excessive irritation to the body surface caused by unidirectional friction, thereby greatly minimizing the possibility of mechanical damage to the skin.

[0045] The ultrasonic therapy device 10 of this embodiment achieves automatic reciprocating rotation of the ultrasonic assembly 200 through the cooperation of an identification sensor and a to-be-identified element 410. Optionally, the present invention includes an identification sensor (e.g., an optical sensor, a Hall effect sensor, or a mechanical contact switch) and an to-be-identified element 410 (e.g., a reflective marker, a magnet, or a raised block).

[0046] In order to enable the to-be-identified part 410 to trigger the identification sensor when the ultrasonic assembly 200 rotates to a preset position, the present invention provides the following two different embodiments.

[0047] Example 1 (inductive trigger):

[0048] In this embodiment, see Figure 2 The identification sensor includes a sensing sensor 310. When the ultrasonic component 200 rotates to a preset position, the part to be identified 410 enters the sensing area of ​​the sensing sensor 310, so that the sensing sensor 310 generates a reversing trigger signal.

[0049] Optionally, the inductive sensor 310 may be a Hall sensor, an optical sensor, or a capacitive proximity sensor. Correspondingly, the object to be identified 410 may be a magnet, a reflective marking sheet, or a metal block.

[0050] Example 2 (contact trigger):

[0051] In this embodiment, the identification sensor includes a contact sensor. When the ultrasonic assembly 200 rotates to a preset position, the to-be-identified member 410 contacts the contact sensor, so that the contact sensor generates a reversing trigger signal.

[0052] Regarding the embodiment in which the identification sensor includes a contact sensor (Embodiment 2), the present invention further provides two different specific circuit embodiments.

[0053] Contact type embodiment 1:

[0054] See also Figure 3 The contact sensor includes a first contact 321 and a second contact 322 that are spaced and insulated. When the ultrasonic component 200 rotates to a preset position, the part to be identified 410 contacts the first contact 321 and the second contact 322 at the same time. The first contact 321 is connected to the second contact 322 through the part to be identified 410, and the contact sensor generates a reversing trigger signal.

[0055] It should be noted that, in this embodiment, the to-be-identified element 410 is made of a conductive material, or its surface is covered with a conductive material.

[0056] Contact type embodiment 2:

[0057] See also Figure 4The contact sensor includes a third contact 330, and the part to be identified 410 is electrically connected to the control part; when the ultrasonic component 200 rotates to a preset position, the part to be identified 410 contacts and conducts with the third contact 330, so that the contact sensor outputs a reversing trigger signal to the control part through the part to be identified 410.

[0058] It should be noted that, in this embodiment, the to-be-identified element 410 is made of a conductive material, or its surface is covered with a conductive material.

[0059] In order to enable the control member to control the rotation of the ultrasonic component 200, in some embodiments, the ultrasonic therapy device 10 further includes a drive component. The drive component is connected to the housing 100. The drive component is connected to the ultrasonic component 200 for driving the ultrasonic component 200 to rotate relative to the housing 100. The control member is in communication connection with the drive component. The communication connection can be via a wired connection and is used to send control instructions to the drive component. The control instructions can be start, stop, adjust the rotation direction, adjust the rotation speed, etc. Specifically, when the control member receives a reversing trigger signal from the identification sensor, the control member sends a reversing instruction to the drive component. In response to the reversing instruction, the drive component changes the rotation direction of its output shaft, thereby driving the ultrasonic component 200 to rotate in the opposite direction.

[0060] Regarding the connection between the drive assembly and the housing 100 and the ultrasonic assembly 200, see Figure 6 The housing 100 has a first side and a second side that are disposed opposite to each other ( Figure 6 The first side of the housing 100 is located above the housing 100, and the second side is located below the housing 100. A relief hole 121 is provided on the housing 100, extending from the first side to the second side. This relief hole 121 extends through the thickness of the housing 100. The ultrasonic assembly 200 is connected to the first side of the housing 100, and the drive assembly is connected to the second side of the housing 100. At least a portion of the drive assembly passes through the relief hole 121 and is drivingly connected to the ultrasonic assembly 200.

[0061] The housing 100 includes a mounting slot 110 and a boss 120 connected to the mounting slot 110. The slot 110 faces the ultrasonic assembly 200 and is connected to the ultrasonic assembly 200. The boss 120 is provided with a cavity structure, and an escape hole 121 is provided on the outer peripheral wall of the boss 120 and communicates with the cavity structure. The drive assembly is connected to the side of the mounting slot 110 facing away from the ultrasonic assembly 200. The side of the mounting slot 110 facing away from the ultrasonic assembly 200 is provided with an opening that communicates with the cavity structure, and a portion of the drive assembly is located within the cavity structure.

[0062] The ultrasonic component 200 includes a mounting member 210 and an ultrasonic transducer 220 and an inner ring gear 230 respectively located on both sides of the mounting member 210. The mounting member 210 is rotatably connected to the housing 100. The inner ring gear 230 is located in a groove formed between the outer peripheral wall of the boss 120 and the inner peripheral wall of the mounting groove 110. The inner ring gear 230 is transmission-connected to the drive assembly and is configured to rotate in the groove formed between the outer peripheral wall of the boss 120 and the inner peripheral wall of the mounting groove 110 under the drive of the drive assembly. Optionally, the inner ring gear 230 is disposed in the groove formed between the outer peripheral wall of the boss 120 and the inner peripheral wall of the mounting groove 110 through a bearing 540 to improve the continuity of the rotation of the inner ring gear 230 and prevent the ultrasonic component from getting stuck during rotation.

[0063] In some embodiments, the drive assembly includes an input gear 510 and an output gear 520. Optionally, the drive assembly also includes a motor 530, which serves as a power source. The motor 530's output shaft is fixedly connected to the input gear 510 to drive the input gear 510 in rotation. The input gear 510 can directly mesh with the output gear 520, or indirectly mesh with the output gear 520 via another gear set, thereby transmitting the rotational power of the motor 530 to the output gear 520. The output gear 520 is drivingly connected to the ultrasonic assembly 200 through a clearance hole 121. Specifically, the output gear 520 is located in the cavity structure and passes through the clearance hole 121 provided on the outer circumferential wall of the housing boss 120. It extends into an annular groove formed between the outer circumferential wall of the boss 120 and the inner circumferential wall of the mounting groove 110. Within this groove, the output gear 520 meshes with the inner ring gear 230 fixedly provided on the mounting member 210 of the ultrasonic assembly, forming a gear pair. Therefore, when the motor 530 is running, its power is transmitted to the inner ring gear 230 through the input gear 510 and the output gear 520 in sequence, thereby driving the ultrasonic component to rotate relative to the housing 100. The control member is electrically connected to the motor 530 and is used to control the start, stop, speed and rotation direction of the motor. Specifically, the control member controls the reverse rotation of the ultrasonic component by controlling the rotation direction of the motor 530: when the motor 530 rotates in a first direction (e.g., clockwise), the ultrasonic component is driven to rotate in the first direction (e.g., clockwise); when the control member needs to control the reverse rotation of the ultrasonic component, that is, the rotation direction of the motor 530 is switched from the first direction to the opposite second direction (e.g., counterclockwise), thereby changing the rotation direction of the output gear 520, thereby driving the inner ring gear 230 and the ultrasonic component fixed thereto to rotate in the second direction (e.g., counterclockwise), thereby achieving reverse movement of the ultrasonic component.

[0064] In some embodiments, the identification sensor is disposed on one end of the boss 120 close to the ultrasonic component 200 through the first circuit board 340. Specifically, the identification sensor is disposed on the top end surface of the boss 120 through the first circuit board 340, so that the identification sensor can stably detect the part to be identified rotating above. In other embodiments, at least one part to be identified 410 is disposed on the ultrasonic component 200, and the identification sensor is disposed on the housing 100. Specifically, when the part to be identified 410 is disposed, the part to be identified 410 can be disposed on the side of the mounting part 210 facing the inner ring gear 230 through the second circuit board 420, so that the first circuit board 340 and the second circuit board 420 are disposed relative to each other in space, and the internal space of the ultrasonic therapy device 10 is fully utilized.

[0065] To enhance the massage effect and user experience of the ultrasonic therapy device 10, the ultrasonic therapy device 10 may further include a massage head 610. The massage head 610 is fixedly mounted on the mounting member 210 and is located on the same side of the mounting member 210 as the ultrasonic transducer 220. When the mounting member 210 rotates relative to the housing 100, the massage head 610 rotates along with the mounting member 210 and the ultrasonic transducer 220. Specifically, the mounting height of the massage head 610 on the mounting member 210 is set to be the same as, or substantially the same as, the height of the ultrasonic transducer 220. This ensures that when the ultrasonic therapy device 10 is in operation, the massage head 610 and the ultrasonic transducer 220 can simultaneously contact the human skin, thereby providing a physical massage effect while the ultrasonic treatment is in progress.

[0066] The ultrasonic therapy device 10 may further include a light-emitting element 620, which is fixedly mounted on the mounting member 210 and located on the same side of the mounting member 210 as the ultrasonic transducer 220. The light-emitting element 620 is configured to emit light when the ultrasonic therapy device 10 is in operation. The light emitted by the light-emitting element 620 is used to visually indicate that the ultrasonic therapy device 10 is currently operating.

[0067] The ultrasonic therapy device 10 may also include a heater, which is disposed on the outer surface of the massage head 610 and may cover or fit over the working surface of the massage head 610. When the massage head 610 contacts and massages the human skin, the heater generates and transfers heat to the contact area, thereby enhancing the user's comfort during use.

[0068] The ultrasonic physiotherapy device 10 further comprises a shell 630, which is provided with an opening, and the ultrasonic assembly 200 is arranged at the opening, so that the ultrasonic assembly 200 can act on the human body through the opening. The shell 100, the driving assembly and the control member are all accommodated and fixed in the internal space of the shell 630. In addition, the shell 630 is connected with a bandage 640, which is configured to be adjustable in length or tightness, for example, is made of magic tape, buckle or elastic material, so that the user can stably fix the entire ultrasonic physiotherapy device 10 on the abdomen or other parts of the human body through the bandage 640, and ensure that the treatment components such as the ultrasonic assembly 200 and the massage head 610 can be in good and stable contact with the skin during the working process of the ultrasonic physiotherapy device 10, so as to perform effective treatment. Optionally, referring to Figure 1 , the bandage 640 is fixed to the shell 630. Optionally, referring to Figure 5 , the shell 630 is connected with the bandage 640 in the form of buckle.

[0069] The working process of the ultrasonic physiotherapy device 10 of the utility model can include the following steps:

[0070] Step S1: the ultrasonic assembly 200 starts to rotate (for example, in the forward direction);

[0071] Step S2: the identification sensor continuously detects the work;

[0072] Step S3: when the to-be-identified member 410 rotates to the preset position with the ultrasonic assembly 200, the identification sensor generates a reversing trigger signal;

[0073] Step S4: the control member responds to the reversing trigger signal and controls the ultrasonic assembly 200 to rotate reversely;

[0074] Step S5: when the to-be-identified member 410 reversely rotates to the preset position with the ultrasonic assembly 200 (which can be different from the preset position in step S3), the identification sensor generates a reversing trigger signal again;

[0075] Step S6: the control member responds to the reversing trigger signal and controls the ultrasonic assembly 200 to reverse the direction (that is, to resume the forward rotation).

[0076] Steps 3 to 6 are cyclically repeated to realize the automatic, continuous and periodic forward and reverse alternating rotation (that is, reciprocating rotation) of the ultrasonic assembly 200 within a predetermined angle range.

[0077] It can be understood that the above embodiments are only exemplary embodiments adopted for illustrating the principles of the utility model, and the utility model is not limited thereto. Those skilled in the art can make various modifications and improvements without departing from the spirit and essence of the utility model, and these modifications and improvements are also regarded as the protection scope of the utility model.
