Abstract
Description
Technical Field
[0001] This invention relates to the field of therapeutic technology, and in particular to a therapeutic device and its therapeutic head. Background Technology
[0002] An ultrasonic therapy device is a skin care treatment device that uses ultrasonic technology. Its basic principle is to utilize the mechanical vibration and thermal effect of ultrasound to deeply stimulate and treat the skin. Ultrasonic therapy devices generally have two types of treatment heads. One type is a point-type treatment head, which is manually operated by the operator, who slides the treatment head across the patient's local treatment area to achieve the treatment. This type of treatment head is suitable for uneven areas of the patient's body.
[0003] However, if the operator is unfamiliar with the product, there is a possibility that the treatment head will not slide during the treatment process, resulting in continuous single-point energy output. This could cause injury to the patient and pose a safety hazard. In addition, if the acoustic window of the treatment head does not fit tightly against the patient's skin, the focused energy of the transducer will act on the patient's epidermis, thus increasing the risk of injury during the treatment. Furthermore, the treatment head needs to slide continuously on the patient's skin during treatment, and the number of slides is high in order to achieve better treatment results. Due to the friction of the treatment head sliding on the skin, the operator is prone to fatigue after a long period of operation, and the patient's skin will also feel uncomfortable due to the back-and-forth friction of the treatment head, resulting in a poor product experience. Summary of the Invention

Detailed Implementation
[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0048] The treatment head provided in this embodiment of the invention is applied to a treatment device, such as... Figure 3 and Figure 4 As shown, the treatment head includes a treatment head body with a treatment surface and an energy conversion module. The energy conversion module can convert energy for treatment and provide energy to the patient's skin through the treatment surface. The treatment head also includes a rolling component, a detection module, and a control module. The rolling component is embedded in the treatment surface of the treatment head body, and its first part is exposed above the treatment surface and can roll relative to the treatment surface. The detection module is disposed in the treatment head body and is used to detect whether the rolling component is rolling. The control module can control the opening and closing of the energy conversion module according to the detection result of the detection module.
[0049] It should be noted that the treatment surface of the treatment head is used to contact and slide against the patient's skin; the energy conversion module can be located inside the treatment head, capable of converting energy for treatment and delivering this energy to the patient's skin through the treatment surface of the treatment head. Figure 3 As shown, the energy conversion module can be an ultrasonic transducer 108; wherein, the ultrasonic transducer 108 can be installed in the liquid-filled treatment head liner 111, and is physically and electrically connected to the corresponding treatment device handheld device 202 via the treatment head latch 105 and the treatment head PCBA. The ultrasonic transducer 108 converts the high-frequency electrical power signal transmitted by the power line into high-frequency vibration through a control chip (which can be in the treatment head or in the handheld device), and then the high-frequency vibration is propagated outward through the liquid in the form of mechanical waves, that is, providing energy to the patient for related treatment through the treatment surface (which can be the acoustic window 102).
[0050] The rolling component is rotatably embedded in the treatment surface of the treatment head body, with its first part exposed above the treatment surface. Since the rolling component rolls, the exposed portion is considered the first part, while the remaining portion lies within the treatment surface. Thus, when the treatment surface of the treatment head body slides in contact with the patient's skin, the rolling component also rolls. In other words, as the treatment surface of the treatment head body slides against the patient's skin, the rolling component rolls along with it. The embedding of the rolling component does not affect the sliding contact between the treatment surface of the treatment head body and the patient's skin. In fact, the embedding of the rolling component helps reduce the sliding friction between the treatment head and the patient's skin, making the treatment smoother during the sliding treatment process, thereby improving the product experience for both the operator and the patient. The rolling component can be a ball bearing component or a roller strip component with good rolling performance; details of the ball bearing component are described below.
[0051] The detection module can be set inside the treatment head body to detect whether the rolling component at the treatment surface of the treatment head body is rolling. In fact, it is also detecting whether the treatment surface of the treatment head body is sliding in contact with the patient's skin.
[0052] The control module is communicatively connected to both the detection module and the energy conversion module, and can control the opening and closing of the energy conversion module based on the detection results of the detection module. The control module can be located within the handheld component 202 of the treatment device, or it can utilize the existing PCBA within the handheld component 202. Alternatively, the control module can be located within the treatment head. When the detection module detects that the rolling component is rolling, the control module can control the energy conversion module to open (in the open state). When the detection module does not detect that the rolling component is rolling, the control module can control the energy conversion module to close (in the closed state). This ensures that the control module can only control the energy conversion module to be open when the treatment surface of the treatment head is in contact with and sliding against the patient's skin. In other words, the energy conversion module can only output energy for treatment when the treatment head slides on the patient's skin. This prevents the operator from being injured, eliminating safety hazards and improving the safety of the treatment head, even if they are unfamiliar with the product.
[0053] In addition, the treatment head 201 (which may be a point treatment head) is a consumable and is detachable from the treatment device. It can be physically fixed to the matching handheld device 202 through the treatment head locking 105. The treatment head 201 and the handheld device 202 are electrically connected through a pogo pin. The handheld device 202 as a whole is electrically connected to the main unit of the treatment device through the handheld device cable 203 to obtain electrical energy. The PCBA embedded inside the handheld device 202 can be used as the control module mentioned above.
[0054] Furthermore, the technical concept of detecting the sliding of the treatment head and controlling the opening and closing of the energy conversion module accordingly, provided in this solution, can be applied to ultrasonic treatment heads, as well as treatment heads of other therapeutic devices, such as electrotherapy heads and phototherapy heads. Specifically, the energy conversion module for phototherapy heads converts electrical energy into light energy; the energy conversion module for radiofrequency treatment heads converts the electrical output of the power supply into high-frequency or mid-to-low-frequency pulse currents suitable for treatment.
[0055] In other words, this solution adds a rolling component, a detection module, and a control module to the existing treatment head. The rolling component is rotatably embedded in the treatment surface of the treatment head body. When the treatment surface of the treatment head body slides against the skin of the area to be treated, the rolling component rolls accordingly. The detection module detects whether the rolling component is rolling, which in turn detects whether the treatment surface of the treatment head body is sliding against the patient's skin. The control module then controls the opening and closing of the energy conversion module based on the detection feedback. That is, the control module can only control the energy conversion module to open when the detection module detects that the rolling component is rolling. In this way, even if the operator is not familiar with the treatment head, it can avoid the situation where the treatment head is not slid and energy is continuously output at a single point during the treatment process, thus preventing the patient from being injured. This avoids the risk of injury to the patient due to the treatment head not being slid during the treatment process, thereby helping to improve the safety performance of the treatment head.
[0056] In this solution, the rolling component includes a magnetic ball assembly; the detection module includes a magnetic field detection module, which is used to detect whether the magnetism of the magnetic field of the magnetic ball assembly changes; the control module can control the opening and closing of the energy conversion module according to the detection result of the magnetic field detection module.
[0057] It should be noted that, as Figure 1As shown, the magnetic ball assembly is embedded in the treatment surface of the treatment head body and is magnetic, which also helps to reduce the sliding friction of the treatment head. The magnetic field detection module can be set inside the treatment head body and is used to detect whether the magnetic field of the magnetic ball assembly changes, that is, to detect whether the magnetic field of the magnetic ball assembly moves. For example, when the treatment head is not sliding, the N pole of the magnetic ball assembly faces or is close to the magnetic field detection module. When contact sliding occurs, the magnetic ball assembly rolls, causing the S pole of the magnetic ball assembly to face or be close to the magnetic field detection module. At this time, the magnetic field detection module can detect the change in the magnetic field of the magnetic ball assembly, thereby determining that the treatment head has come into contact with the patient's skin and has slid. In addition, when the magnetic field detection module detects a change in the magnetic field of the magnetic ball assembly, the control module can control the energy conversion module to turn on accordingly; when the magnetic field detection module does not detect a change in the magnetic field of the magnetic ball assembly, the control module can control the energy conversion module to turn off accordingly.
[0058] In other words, in this solution, the detection module detects whether the rolling component is rolling by detecting whether the magnetic field of the magnetic ball component changes, which makes the rolling detection of the rolling component more convenient and effective. Of course, as mentioned above, this rolling component can also use a roller assembly, and the detection principle can be the same, which will not be repeated here.
[0059] Specifically, such as Figure 1 As shown, the magnetic ball assembly includes multiple magnetic balls 103; the multiple magnetic balls 103 are respectively embedded in the treatment surface of the treatment head body, and their first parts are exposed on the treatment surface and can roll relative to the treatment surface; the magnetic field detection module is used to detect whether the magnetism of the magnetic field of the multiple magnetic balls 103 changes.
[0060] It should be noted that multiple magnetic balls 103 are respectively rolled and embedded in the treatment surface of the treatment head body. The first part of each magnetic ball 103 is exposed on the treatment surface and is used to contact the patient's skin. They also roll when the treatment head is slid. This can help reduce the sliding friction between the treatment head and the patient, reduce operator fatigue caused by long-term operation, and also reduce patient discomfort during treatment. Of course, the magnetic balls 103 are magnetic. When the magnetic balls 103 roll, the magnetism of their magnetic field will change. In fact, the orientation of the magnetic field (N pole or S pole) will change.
[0061] The magnetic field detection module may include multiple magnetic field detection units, which may be arranged inside the treatment head body and distributed one-to-one with multiple magnetic balls 103 (e.g., relatively distributed) so that the magnetic properties of the magnetic fields of the multiple magnetic balls 103 can be detected one by one. This helps to ensure the accuracy of the magnetic field detection module. Of course, the magnetic field detection unit detects whether the magnetic properties of the magnetic fields of the magnetic balls 103 have changed, which is actually detecting whether the magnetic balls 103 are rolling.
[0062] The control module can control the opening and closing of the energy conversion module according to the detection results of multiple magnetic field detection units. Specifically, when two opposing magnetic field detection units detect a change in the magnetism of the corresponding magnetic ball 103, the control module can control the energy conversion module to open. When none of the multiple magnetic field detection units detect a change in the magnetism of the corresponding magnetic ball 103, the control module can control the energy conversion module to close.
[0063] In other words, multiple magnetic balls 103 with excellent rolling effect are embedded in the treatment surface of the treatment head. This reduces the sliding friction between the treatment head and the patient's skin through the rolling friction of the multiple magnetic balls 103, making the treatment head smoother and more responsive during the treatment process. This effectively improves the user experience for both the operator and the patient. Furthermore, the treatment surface of the treatment head has multiple magnetic balls 103, which reduces the friction during sliding on the patient's skin, making the treatment or operation process smoother and more responsive, ensuring a better user experience. In addition, multiple magnetic field detection units are set inside the treatment head to detect the status of each magnetic ball 103, enabling real-time detection of the sliding contact between the treatment head and the patient's skin. This avoids the risk of injury to the patient due to lack of sliding during treatment, thus improving the safety of the treatment head.
[0064] Furthermore, the magnetic ball 103 only tends to roll when the contact pressure reaches the pressure threshold.
[0065] It should be noted that the patient's skin contacts the magnetic ball 103 and applies pressure. Rolling only occurs when a pressure threshold is reached. At this point, the treatment head is in close or tight contact with the patient's skin because the contact pressure on the magnetic ball 103 is at its maximum. Furthermore, simply sliding the treatment head will cause the magnetic ball 103 to roll. Of course, this pressure threshold can be greater than the sliding friction (sliding resistance) experienced by the magnetic ball 103 at the treatment surface, but it cannot be too high to avoid the treatment head applying excessive thrust during sliding treatment. In other words, the magnetic ball 103 at the treatment surface of the treatment head has… With a certain level of damping, the magnetic ball 103 only tends to roll when the treatment head is properly aligned with the patient's skin (i.e., when a certain contact pressure is met). This prevents the treatment surface of the treatment head from accidentally rolling due to light contact with the patient's skin. It also ensures that the treatment head and the patient's skin are in proper contact before the energy conversion module is activated. When the treatment head is properly aligned, there are no gaps between it and the skin, preventing the ultrasound waves from being affected by gaps. This ensures that the focused energy of the ultrasound transducer acts on the patient's skin, thus avoiding the risk of injury to the patient during treatment. Of course, the detection of rolling of the magnetic ball 103 also indicates that the treatment head has made proper contact or adhered properly to the patient's skin.
[0066] In other words, this solution provides a treatment head with magnetic balls to reduce sliding friction and sliding detection and adhesion detection functions; wherein, the treatment head can be a point-type ultrasonic treatment head.
[0067] In addition, the magnetic field detection module is also used to detect the rate of change of the magnetic field of the magnetic ball assembly, and to determine whether the moving speed of the treatment head is greater than the speed threshold based on the rate of change of the magnetic field of the magnetic ball assembly; the control module can also control the opening and closing of the energy conversion module based on the judgment result of the magnetic field detection module.
[0068] It should be noted that, as mentioned above, the magnetic field detection module includes multiple magnetic field detection units, and the magnetic ball assembly includes multiple magnetic balls 103. The multiple magnetic field detection units are also used to detect the rate of change of the magnetic field of each of the multiple magnetic balls 103, and the magnetic field detection units can also determine whether the movement speed of the treatment head is greater than a speed threshold based on the rate of change of the magnetic field of the magnetic balls 103. The control module can also control the opening and closing of the energy conversion module based on the judgment result of at least one magnetic field detection unit. The rate of change of the magnetic field of the magnetic balls 103 is positively correlated with the movement speed of the treatment head; that is, the greater the movement speed of the treatment head (the faster it slides), the greater the rate of change of the magnetic field of the magnetic balls 103. In other words, the faster the treatment head slides, the faster the magnetic field of the magnetic balls 103 changes.
[0069] When the magnetic field detection module determines that the moving speed of the treatment head is greater than the speed threshold based on the rate of change of the magnetic field of the magnetic ball assembly, the control module can control the energy conversion module to start based on the determination result. That is, when the sliding speed of the treatment head reaches its speed threshold, the control module can control the energy conversion module to start based on this result. In particular, when at least two opposing magnetic field detection units determine that the moving speed of the treatment head is greater than the speed threshold based on the rate of change of the magnetic field of the corresponding magnetic ball 103, the control module can control the energy conversion module to start based on this.
[0070] When the magnetic field detection module determines that the movement speed of the treatment head is not greater than the speed threshold based on the rate of change of the magnetic field of the magnetic ball assembly, the control module can control the energy conversion module to shut down based on this determination result. That is, when the sliding speed of the treatment head does not reach its speed threshold, the control module can control the energy conversion module to shut down based on this result. Specifically, when all magnetic field detection units determine that the movement speed of the treatment head is greater than the speed threshold based on the rate of change of the magnetic field of the corresponding magnetic ball 103, the control module can control the energy conversion module to shut down based on this result. In this way, the energy conversion module can only be triggered to open when the sliding speed of the treatment head reaches a certain threshold (speed threshold), thereby ensuring that the treatment head works at a specified movement speed and avoiding the pain and damage caused by concentrated energy irradiation on a small area at too slow an operating speed.
[0071] Furthermore, such as Figure 1 As shown, multiple magnetic rollers 103 are evenly distributed around the center of the treatment surface.
[0072] As mentioned above, the magnetic field detection module includes multiple magnetic field detection units.
[0073] Multiple magnetic field detection units are respectively set inside the treatment head body and are distributed one-to-one with multiple magnetic balls 103; among them, the multiple magnetic field detection units are used to detect whether the magnetism of the magnetic field of the multiple magnetic balls 103 changes.
[0074] The control module can control the opening and closing of the energy conversion module based on the detection results of multiple magnetic field detection units. Of course, the multiple magnetic field detection units can also be evenly distributed around the center of the treatment surface.
[0075] It should be noted that, as Figure 1 As shown, the treatment surface of the treatment head body has an acoustic window 102, and multiple magnetic balls 103 are distributed on the outer side of the acoustic window 102 and evenly distributed around the center of the acoustic window 102. This not only ensures that the treatment head slides smoothly during the treatment process, but also ensures that the treatment head has a good appearance, and also facilitates multi-directional sliding detection of the treatment surface of the treatment head. For example, Figure 1As shown, the number of magnetic balls 103 can be six, and they can be evenly distributed around the center of the acoustic window 102. Moreover, as mentioned above, when the magnetic field of two opposing magnetic balls 103 changes, it can be determined that the treatment head is sliding in contact with the patient's skin. At this time, the control module can control the energy conversion module to start.
[0076] In this scheme, the magnetic field detection unit is a unipolar magnetic field detection unit, used to detect whether the magnetism of the N pole of the magnetic field of the magnetic ball 103 changes. The relative position of the unipolar magnetic field detection unit and the corresponding magnetic ball 103 is fixed. During the rolling process of the magnetic ball 103, the magnetism of its N pole changes, such as... Figure 6 As shown, the orientation of the N pole of its magnetic field will change. The magnetic field of the magnetic ball 103 can be detected by the unipolar magnetic field detection unit to see if the magnetism of the N pole of the magnetic field changes, thus making it easier to detect whether the magnetic ball 103 is rolling.
[0077] Specifically, such as Figure 4 As shown, the unipolar magnetic field detection unit includes a unipolar Hall sensor 110;
[0078] Among them, such as Figure 6 As shown, when the magnetic ball 103 rolls until its magnetic field N pole faces or approaches the unipolar Hall sensor 110, the unipolar Hall sensor 110 can output a low level.
[0079] When the magnetic ball 103 rolls until its magnetic field N pole is far away from the unipolar Hall sensor 110, the unipolar Hall sensor 110 can output a high level.
[0080] It should be noted that the N pole of the magnetic field of the magnetic ball 103 can be located on the first side of the hemispherical split surface (preset) of the magnetic ball 103, and the S pole of the magnetic field of the magnetic ball 103 can be located on the second side of the hemispherical split surface of the magnetic ball 103.
[0081] Specifically, when the N pole of the magnetic field of the magnetic ball 103 approaches the unipolar Hall sensor 110, such as Figure 6 As shown in the three small figures above, the first side of the hemispherical segmented surface of the magnetic ball 103 faces the unipolar Hall sensor 110 and can be at a certain angle to the unipolar Hall sensor 110. Of course, at this time, the second side of the hemispherical segmented surface of the magnetic ball 103 faces away from the unipolar Hall sensor 110.
[0082] When the N pole of the magnetic field of the magnetic ball 103 moves away from the unipolar Hall sensor 110, such as Figure 6As shown in the three small figures below, the second side of the hemispherical segmented surface of the magnetic ball 103 faces the unipolar Hall sensor 110 and can be at a certain angle to the unipolar Hall sensor 110. Of course, at this time, the first side of the hemispherical segmented surface of the magnetic ball 103 faces away from the unipolar Hall sensor 110.
[0083] More specifically, such as Figure 6 As shown in the three small figures above, when the magnetic ball 103 rolls to the point where its magnetic field N pole faces or approaches the unipolar Hall sensor 110, the unipolar Hall sensor 110 can detect the N pole of the magnetic ball 103 and output a low level. Moreover, the low level output by the unipolar Hall sensor 110 is the same regardless of whether the magnetic field N pole of the magnetic ball 103 faces or approaches the unipolar Hall sensor 110.
[0084] like Figure 6 As shown in the three small figures below, when the magnetic ball 103 rolls until its magnetic field N pole is far away from (e.g., away from) the unipolar Hall sensor 110, that is, when the magnetic ball 103 rolls until its magnetic field S pole is facing or close to the unipolar Hall sensor 110, the unipolar Hall sensor 110 fails to detect the N pole of the magnetic ball 103 and output a high level. Moreover, regardless of whether the magnetic field S pole of the magnetic ball 103 is facing or close to the unipolar Hall sensor 110, the high level output by the unipolar Hall sensor 110 is the same.
[0085] like Figure 6 As shown in the small diagram on the far right of the top, when the magnetic ball 103 rolls until the line connecting its N and S poles is parallel to the unipolar Hall sensor 110, and the N pole of the magnetic ball 103 is facing to the right and the S pole is facing to the left, the output level of the unipolar Hall sensor 110 increases, that is, the output rising edge.
[0086] like Figure 6 As shown in the small diagram on the far right at the bottom, when the magnetic ball 103 rolls until the line connecting its N and S poles is parallel to the unipolar Hall sensor 110, and the N pole of the magnetic ball 103 faces left and the S pole faces right, the output level of the unipolar Hall sensor 110 decreases, that is, it outputs a falling edge.
[0087] In other words, when the output level of the unipolar Hall sensor 110 changes (increases or decreases), it can be determined that the magnetism of the N pole of the magnetic field of the corresponding magnetic ball 103 has changed, and thus it can be determined that the corresponding magnetic ball 103 is rolling. That is, by determining whether the output level of the unipolar Hall sensor 110 changes, this method determines whether the corresponding magnetic ball 103 is rolling. Specifically, when the unipolar Hall sensor 110 outputs a rising edge or a falling edge, it can be determined that the corresponding magnetic ball 103 is rolling.
[0088] Of course, the initial position of the magnetic ball 103 is random. When the treatment head is stationary and does not slide, the low or high level output by the unipolar Hall sensor 110 is fixed. Only when the level output by the unipolar Hall sensor 110 changes can it be determined that the corresponding magnetic ball 103 is rolling. Moreover, for a single magnetic ball 103, the duty cycle of the high level is 50% during the uniform circling process.
[0089] Furthermore, such as Figure 1 As shown, when the treatment head 201 slides against the patient's skin, the magnetic ball 103 also rolls. Because the magnetic ball 103 is magnetic, magnetic field lines 301 of different polarities and angles move and change at the unipolar Hall sensor 110 above it. When the N pole of the magnetic ball 103 is approximately aligned with the unipolar Hall sensor 110, the unipolar Hall sensor 110 outputs a low level. When the magnetic ball 103 rotates until its S pole is approximately aligned with the unipolar Hall sensor 110, the unipolar Hall sensor 110 cannot detect the N pole of the magnetic ball 103 and outputs a high level. Furthermore, during the rotation from the N pole to the S pole or vice versa, the unipolar Hall sensor 110 outputs a rising or falling edge. When the magnetic ball 103 is stationary, the unipolar Hall sensor 110 outputs a high level. 0 will continuously output a high or low level; therefore, this solution determines whether the magnetic ball 103 rolls by detecting the rising or falling edge output of the unipolar Hall sensor 110. Only when the treatment head is in good contact with the patient's skin and sliding treatment is performed will multiple unipolar Hall sensors on the treatment head output rising or falling edges. This solution uses this detection logic for sliding detection and contact detection. When both opposite unipolar Hall sensors 110 on the treatment head output rising / falling edges, the power output of the ultrasonic transducer 108 is controlled by the PCBA (i.e., the control module mentioned above) embedded inside the handheld component 202. In this way, the ultrasonic transducer 108 can output energy for treatment when the treatment head contacts and slides on the patient's skin.
[0090] In other words, the magnetic ball 103 used in this solution is magnetic. By placing a unipolar Hall sensor 110 in a specific position inside the treatment head, it is easy to effectively detect whether the magnetic ball 103 is rolling. This enables sliding detection (displacement detection) and fit detection of the treatment head, avoiding the risk of injury to the patient due to sliding and fit problems during the treatment process, thereby improving the safety of the treatment head.
[0091] Furthermore, such as Figure 1 As shown, the treatment head body has a face cover 104, and the outer end face of the face cover 104 serves as part of the treatment surface of the treatment head body.
[0092] like Figure 4 As shown, the treatment head also includes a support 112.
[0093] like Figure 3 As shown, the support 112 is disposed inside the treatment head body and is located inside the faceplate 104.
[0094] Multiple magnetic balls 103 are respectively rotatably mounted between the faceplate 104 and the first end of the bracket 112, and their first parts are all exposed above the faceplate 104.
[0095] Multiple magnetic field detection units are respectively set at the second end of the bracket 112 and are distributed one-to-one with multiple magnetic balls 103.
[0096] It should be noted that, as Figure 1 As shown, the outer end face of the faceplate 104 serves as part of the treatment surface of the treatment head body, while the remaining part of the treatment surface of the treatment head body is the outer end face of the acoustic window 102, meaning the faceplate 104 can surround the outer side of the acoustic window 102; the support 112 is built into the treatment head body and located inside the faceplate 104, and as... Figure 3 As shown, the support 112 can be limited and fixed through components such as the treatment head shell 101, the face cover 104, and the treatment head inner liner 111; multiple magnetic balls 103 can be rolled between the face cover 104 and the first end of the support 112, as shown. Figure 2 As shown, the first part of each of them is exposed above the cover 104; wherein, the first part of the magnetic ball 103 is exposed above the cover 104 and can roll very smoothly without falling off; and the cover 104 is also equivalent to the cover of the magnetic ball; multiple magnetic field detection units can be respectively installed in the second end of the bracket 112 and are distributed one-to-one with the multiple magnetic balls 103; wherein, the magnetic field detection unit is a unipolar Hall sensor 110, which can detect whether the unipolar magnetism (N pole) of the magnetic ball 103 changes when powered on, and transmit the detection status to the PCBA of the handheld device 202 through the Hall sensor lead 109, that is, output level to the PCBA of the handheld device 202. The PCBA of the handheld device 202 further determines whether the unipolar magnetism (N pole) of the magnetic ball 103 changes, and thus determines whether the magnetic ball 103 rolls, thereby determining (detecting) whether the treatment head slides or contacts the patient's skin. In addition, as Figure 4 As shown, the first end of the bracket 112 can be the front end, and the second end can be the rear end.
[0097] In other words, this design facilitates the embedding of multiple magnetic rollers 103 on the treatment surface of the treatment head body, and allows for the integration of multiple magnetic field detection units into the treatment head body. Of course, this treatment head can also be used to treat patients by contacting and sliding it upwards against their skin.
[0098] Furthermore, the cover 104 has multiple through first mounting slots for mounting the middle portions of multiple magnetic balls 103 one by one.
[0099] The first end of the bracket 112 has multiple second mounting slots for mounting the second parts of multiple magnetic balls 103 one by one, and the second end of the bracket 112 has multiple third mounting slots for mounting multiple magnetic field detection units one by one.
[0100] Among them, multiple first mounting slots are distributed opposite to multiple second mounting slots, and multiple second mounting slots are distributed opposite to multiple third mounting slots.
[0101] It should be noted that the middle part of the multiple magnetic balls 103 is used to install one by one into the multiple first mounting slots of the face cover 104, and the second part is used to install one by one into the multiple second mounting slots of the first end of the bracket 112. Moreover, the structure of the first mounting slot is adapted to the structure of the middle part of the magnetic ball 103, and the structure of the second mounting slot is adapted to the structure of the second part of the magnetic ball 103. In this way, the multiple magnetic balls 103 can be respectively limited and installed between the face cover 104 and the first end of the bracket 112, which also allows the multiple magnetic balls 103 to be rolled and locked between the face cover 104 and the first end of the bracket 112. This can prevent the multiple magnetic balls 103 from falling off the treatment surface and also facilitates the one-to-one relative setting of the multiple magnetic balls 103 and the multiple magnetic field detection units.
[0102] In this plan, such as Figure 1 As shown, the face cover 104 is an annular face cover, and multiple first mounting grooves are distributed around the center of the annular face cover.
[0103] like Figure 4 As shown, bracket 112 is a ring bracket, and multiple second mounting slots and multiple third mounting slots are distributed around the center of the ring bracket.
[0104] It should be noted that, as Figure 1 As shown, the annular cover surrounds the outer side of the acoustic window 102, and the number of the first mounting slots can be six, distributed around the center of the annular cover, so that the multiple magnetic balls 103 can be evenly distributed around the center of the acoustic window 102; as Figure 3 As shown, the annular bracket is fitted on the outer side of the front end of the treatment head inner liner 111, and as described above, it can be limited and fixed by components such as the treatment head outer shell 101, the face cover 104, and the treatment head inner liner 111; multiple second mounting slots and multiple third mounting slots are distributed around the center of the annular bracket, so that multiple magnetic balls 103 can be evenly distributed around the center of the acoustic window 102, and multiple magnetic field detection units can be evenly distributed around the center of the acoustic window 102.
