Treatment head and therapeutic apparatus

Abstract

The application discloses a treatment head and a therapeutic instrument. The treatment head comprises a first shell, a second shell, a diaphragm structure, a magnet and a Hall element. The second shell comprises a treatment surface. The diaphragm structure is installed on the treatment surface and is used for being attached to the skin. The magnet is installed on one of the diaphragm structure and the first shell. The Hall element is installed on the other one of the diaphragm structure and the first shell, and the Hall element is spaced apart from the magnet. In the process of movement of the magnet, the magnetic flux changes, for example, the magnetic flux increases when the magnet approaches the Hall element, and the magnetic flux decreases when the magnet moves away. The Hall element is not affected by objective factors such as brightness. This makes the treatment head more accurately detect the movement of the magnet relative to itself, such as detecting whether the magnet has a circumferential deflection or a height change, so as to accurately perceive whether the treatment head slides on the skin, ensure the stable work of the therapeutic instrument, and improve the treatment experience of the user.

Description

Technical Field

[0001] This application relates to the field of medical device technology, and more particularly to treatment heads and treatment devices. Background Technology

[0002] During the use of a therapeutic device, it is often necessary to slide the treatment head back and forth on the skin. Currently, most therapeutic devices on the market use pressure sensors or light sensors for sliding detection. However, these two types of sensors have relatively high requirements for objective factors. For example, the sensitivity of pressure sensors decreases significantly over time, and light sensors have high requirements for light sources. They are prone to not triggering in relatively dark environments, thus failing to accurately determine whether the treatment head is sliding. This results in unstable energy output from the therapeutic device and affects the user's treatment experience. Utility Model Content

[0003] This application provides a treatment head and a treatment device to accurately sense whether the treatment head is sliding, ensure the stable operation of the treatment device, and improve the user's treatment experience.

[0004] The first aspect of this application provides a treatment head, comprising:

[0005] First shell;

[0006] A second housing, the second housing including a treatment surface;

[0007] A membrane structure is mounted on the treatment surface and is designed to adhere to the skin.

[0008] A magnet, the magnet being mounted on one of the diaphragm structure and the first housing;

[0009] A Hall element is mounted on the other of the diaphragm structure and the first housing, and the Hall element is spaced apart from the magnet. The Hall element is used to detect the movement of the magnet relative to itself.

[0010] Optionally, the height difference between the magnet and the Hall element is between 0 and 2.5 mm.

[0011] Optionally, the diaphragm structure includes a diaphragm body and an elastic protrusion, the elastic protrusion protruding at least partially from the side of the diaphragm body away from the treatment surface, the elastic protrusion being movable relative to the diaphragm body toward or away from the first housing, the magnet being connected to the elastic protrusion, and the magnet being located between the elastic protrusion and the first housing.

[0012] Optionally, the diaphragm structure has a groove structure on the side near the second housing, the groove structure is located at the elastic protrusion, and the magnet is installed in the groove structure.

[0013] Optionally, the treatment head further includes an alignment portion located between the treatment surface and the first housing, the alignment portion being used to limit the distance between the Hall element and the magnet in a first direction to no more than a preset distance.

[0014] Optionally, the first housing includes a target end, the circumferential surface of which has a positioning notch, the target end being close to the treatment surface, the Hall element being mounted on a circuit board, and the positioning notch defining the placement position of the circuit board on the target end.

[0015] Optionally, the second housing includes an extension located between the treatment surface and the first housing, extending away from the treatment surface; the first housing includes a liquid reservoir, the circumferential surface of which is provided with a barrier, the barrier engaging with the extension to connect the first housing and the second housing.

[0016] Optionally, the treatment head further includes an elastic element, the first housing and the second housing are slidably connected by the elastic element, the second housing can drive the diaphragm structure to move closer to or away from the first housing, and the elastic element is used to reset the second housing relative to the first housing after it moves.

[0017] A second aspect of this application provides a therapeutic device, including a handle and a therapeutic head described in the first aspect or any specific example of the first aspect.

[0018] Optionally, the treatment device further includes a gyroscope chip, which is mounted on the treatment head or the handle; the gyroscope chip is used to detect the movement of the treatment device, and when the detection result of the treatment head is also movement, it drives the treatment device to output energy to the skin.

[0019] As can be seen from the above technical solutions, the embodiments of this application have at least the following advantages:

[0020] This embodiment combines a Hall element and a magnet for sliding detection because the magnetic flux changes during the movement of the magnet. For example, the magnetic flux increases when the magnet approaches the Hall element and decreases when it moves away. Furthermore, the Hall element is unaffected by objective factors such as brightness. This allows this embodiment to more accurately detect the movement of the magnet relative to itself, such as whether the magnet has undergone circumferential deflection or height change. This accurately senses whether the treatment head is sliding back and forth on the skin, ensuring stable operation of the treatment device and improving the user's treatment experience.

[0031] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0032] In the description of the embodiments of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc. (if present), indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are used only for the convenience of describing the embodiments of this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application. Furthermore, the terms "first," "second," and "third" are used only for descriptive purposes such as distinguishing similar objects, and should not be construed as indicating or implying relative importance or order.

[0033] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0034] The first aspect of this application provides an embodiment of a treatment head, which includes: a first housing 1; a second housing 2, the second housing 2 including a treatment surface 21; a diaphragm structure 22, the diaphragm structure 22 being mounted on the treatment surface 21 and used to adhere to the skin; a magnet 3, the magnet 3 being mounted on one of the diaphragm structure 22 and the first housing 1; and a Hall element 4, the Hall element 4 being mounted on the other of the diaphragm structure 22 and the first housing 1, and the Hall element 4 being spaced apart from the magnet 3, the Hall element 4 being used to detect the movement of the magnet 3 relative to itself.

[0035] As explained above, the magnet 3 and the Hall element 4 can be mounted on the first housing 1 and the diaphragm structure 22, respectively. Please refer to [link / reference]. Figure 1 , Figure 2 The second housing 2 (which can be regarded as a treatment head cover) can be provided with a diaphragm structure 22 on the treatment surface 21. When the treatment surface 21 slides close to the skin, the diaphragm structure 22 will be squeezed by the skin. The magnet 3 (or magnet) installed on the diaphragm structure 22 will also move under pressure, such as rising and falling in the vertical direction or deflecting and swaying left and right in the horizontal direction. During the movement, the magnet 3 will move closer to and away from the Hall element 4. During the movement of this magnet, the magnetic flux will change. For example, the magnetic flux increases when it is close to the Hall element 4 and decreases when it is away. Therefore, by detecting the change in magnetic flux, it can be confirmed that the treatment device is sliding.

[0036] The Hall element 4 mentioned above can specifically be a sensitive element in the Hall sensor flexible printed circuit board 12 (FPCA), which will not be described in detail here. It can be seen that the embodiments of this application can sense changes in magnetic flux through a linear Hall sensor, thereby achieving sliding detection. This magnetic flux is mainly provided by the magnet 3. Because the environment has little influence on the magnet, and the magnet's magnetic decay period is relatively long, the linear Hall sensor of this embodiment can continuously and stably receive signals, greatly improving detection sensitivity and thus enhancing treatment efficiency.

[0037] In summary, the sliding detection in this embodiment combines Hall element 4 and magnet 3 because the magnetic flux changes during the movement of magnet 3. For example, the magnetic flux increases when magnet 3 approaches Hall element 4 and decreases when it moves away. Furthermore, Hall element 4 is unaffected by objective factors such as brightness. This allows this embodiment to more accurately detect the movement of magnet 3 relative to itself, such as whether magnet 3 has undergone circumferential deflection or height change, thereby accurately sensing whether the treatment head is sliding back and forth on the skin, ensuring stable operation of the treatment device, and improving the user's treatment experience.

[0038] Based on the above examples, this application will be further described in detail below, and some specific possible implementation examples will be provided. In practical applications, the implementation content of these examples can be combined or implemented separately as needed according to the corresponding functional principles and application logic, and the specific implementation can be determined according to the actual scenario.

[0039] In some specific examples, the vertical height difference between the magnet 3 and the Hall element 4 (i.e., with the Hall element 4 as the zero point) is between 0 and 2.5 mm, such as the magnet 3 being on top and the Hall element 4 being below, or their vertical positions being reversed. Of course, other height differences can also be set according to the internal space characteristics of the treatment head. In addition, the horizontal distance between the magnet 3 and the Hall element 4 can also be determined according to the actual situation, and there are no specific restrictions here, in order to meet the space utilization requirements.

[0040] In some specific examples, the above-mentioned diaphragm structure 22 includes a diaphragm body 221 and an elastic protrusion 222. The elastic protrusion 222 protrudes at least partially from the side of the diaphragm body 221 away from the treatment surface 21. The elastic protrusion 222 can move relative to the diaphragm body 221 toward or away from the first housing 1. The magnet 3 is connected to the elastic protrusion 222 and is located between the elastic protrusion 222 and the first housing 1.

[0041] like Figure 3As shown, four elastic protrusions 222 (which may be called bumps or silicone buttons) can be distributed on the membrane body 221 (such as a silicone membrane). These four elastic protrusions 222 can be evenly distributed to receive the deformation force generated by the pressure of contact with the skin surface. Of course, the number and distribution characteristics of the elastic protrusions 222 can be determined according to the actual situation, and are not limited here.

[0042] Taking one of the elastic protrusions 222 as an example, in actual application, when the treatment head slides close to the skin surface, the elastic protrusion 222 will be pressed down in the direction of the Hall sensor, i.e., undergo elastic deformation (which can be regarded as concave). This causes the magnet 3 connected to the elastic protrusion 222 to swing left and right and / or move down. As the magnet 3 moves, the signal value (such as magnetic flux) between the magnet 3 and the sensor (specifically, the Hall element 4 in the Hall sensor) will change. The processor of its sensing circuit board can identify that the treatment head (specifically, the elastic protrusion 222) has slid on the skin surface through this signal value, thereby triggering the transducer of the treatment device (not shown in the figure) to output energy to the skin surface, such as outputting ultrasound or light energy for treatment.

[0043] In some specific examples, the diaphragm structure 22 has a groove structure on the side near the second housing 2. The groove structure is located at the elastic protrusion 222, and the magnet 3 is installed in the groove structure. This design can reduce the space occupied inside the housing from the source and improve space utilization. Alternatively, a part of the diaphragm structure 22 is an elastically movable part, which may not be a groove structure but can still drive the magnet 3 to move. In some examples, the magnet 3 and the diaphragm structure 22 can be bonded or connected through other intermediaries.

[0044] In some specific examples, the treatment head of this application embodiment may further include an alignment part 5, which is located between the treatment surface 21 and the first housing 1. The alignment part 5 is used to limit the distance between the Hall element 4 and the magnet 3 in the first direction to no more than a preset distance.

[0045] As explained above, an alignment part 5 can be provided between the Hall element 4 and the magnet. This alignment part 5 can be a columnar structure or other structures, mainly used for positioning. Figure 3 As shown, when the alignment part 5 is a columnar structure, its size can be larger than the size of the magnet, thus enclosing the magnet 3. This column can be positioned below the four bulges of the silicone diaphragm to facilitate accurate alignment of the Hall element 4 and the magnet 3 during assembly, ensuring that they are assembled on the same vertical line, i.e., the interval in the first direction (which can be considered as the left-right interval in the horizontal direction) does not exceed a preset distance. Of course, in some examples, the alignment part can be a reference point for alignment, rather than... Figure 3 The structural components shown can be customized as needed.

[0046] In some specific examples, the first housing 1 includes a target end 11, the circumferential surface of which has a positioning notch 111, the target end is close to the treatment surface 21, the Hall element 4 is mounted on the circuit board 12, and the positioning notch 111 is used to define the placement position of the circuit board 12 on the target end.

[0047] like Figure 4-1 As shown, multiple Hall elements 4 and other electronic components are pre-installed on the circuit board 12 (such as a Hall sensor FPCA). During assembly, the components can be positioned through the positioning notch 111 on the target end 11 (such as...). Figure 4-2 As shown, the placement position (such as orientation) of the circuit board 12 on the target end is determined so that the above-mentioned multiple Hall elements 4 can be aligned with the upper elastic protrusion 222, that is, the Hall elements 4 are positioned in the assembly.

[0048] It should be noted that, Figure 2 The internal structure of the second housing 2 shown is as follows Figure 4-1 As shown (i.e., upside down) Figure 2 (See the rear view of the second housing 2 shown). Once assembled, the second housing 2 will cover or enclose at least some components of the first housing 1. Furthermore, as... Figure 4-1 As shown, a cover 14 (which can protect and / or fix the liquid storage cavity 13) can be provided on the outside of the liquid storage cavity 13. The second housing 2 (on top) and the cover 14 (on bottom) can be assembled and fixed by mutually cooperating anti-fooling part 16 (or limiting part) to avoid errors or excessive assembly time when assembling the two.

[0049] In some specific examples, the second housing 2 includes an extension 23 located between the treatment surface 21 and the first housing 1 and extending away from the treatment surface 21; the first housing 1 includes a liquid reservoir 13, and the circumferential surface of the liquid reservoir 13 is provided with one or more blocking portions 131, which cooperate with the extension 23 to achieve the connection between the first housing 1 and the second housing 2.

[0050] like Figure 2 As shown, the extension 23 of the second housing 2 can be a screw post, and multiple blocking parts 131 can be provided at intervals around the periphery of the liquid storage cavity 13. The extension 23 can be accommodated in the gap formed by two adjacent blocking parts 131, or the extension 23 can directly abut against the blocking part 131, so that the first housing 1 and the second housing 2 can be mutually connected. The screw post and the blocking part 131 can be fixed by screws to enhance the stability between the first housing 1 and the second housing 2 (i.e., the two can be fixedly connected).

[0051] As explained above, during the process of the treatment head sliding close to the skin, the elastic protrusion 222 on the membrane structure 22 will be pressed and deformed, thereby causing the magnet 3 connected to the elastic protrusion 222 to move closer to or away from the Hall element 4. During this movement, the magnetic flux will increase or decrease. As long as the circuit board 12 (or circuit board) detects the change in magnetic flux, the transducer will start and output ultrasonic energy.

[0052] In practical applications, the aforementioned liquid storage chamber 13 serves as a container for guiding water. The circulating cooling water in it can balance the temperature and prevent the output energy from scalding the skin. On the other hand, it can also serve as a sound wave transmission medium (if it is an ultrasonic treatment head), eliminating the air gap between the transducer inside the treatment head and the skin, effectively ensuring that the energy is efficiently transmitted to the skin and improving the user experience.

[0053] In some specific examples, the treatment head may also include an elastic element (not shown in the figure), the first housing 1 and the second housing 2 are slidably connected by the elastic element, the second housing 2 can drive the diaphragm structure 22 to move toward or away from the first housing 1, and the elastic element is used to reset the second housing 2 after it moves relative to the first housing 1.

[0054] In practice, when the treatment surface 21 of the second housing 2 slides on the skin, the second housing 2 as a whole can move towards the first housing 1, thereby driving the magnet 3 to approach the Hall element 4 on the first housing 1 to trigger the transducer to output ultrasonic energy. When the treatment surface 21 moves away from the skin, the elastic element can use its elasticity to help the second housing 2 move relative to the first housing 1 and return to its original position, so that the treatment head can be reused for energy output in the future.

[0055] In one embodiment, the elastic element may be provided at the end or inside of the extension 23 of the second housing 2. The extension 23 restricts the relative movement between the first housing 1 and the second housing 2 in a direction perpendicular to the axial direction of the extension 23, while allowing the first housing 1 and the second housing 2 to move relative to each other within a certain range along the axial direction of the extension 23.

[0056] The second aspect of this application provides an embodiment of a therapeutic device, which includes a handle and a therapeutic head as described in the first aspect or any specific example of the first aspect, as detailed above, and will not be repeated here.

[0057] In some specific examples, the aforementioned therapeutic device may also include a gyroscope chip mounted on the treatment head or handle; the gyroscope chip is used to detect the movement of the therapeutic device, and when the detection result of the treatment head is also movement, it drives the therapeutic device to output energy to the skin.

[0058] The reason for combining the detection results of the gyroscope chip and Hall element 4 to output energy is that if the treatment head simply contacts the skin without sliding, there may be a certain degree of pressure that causes the magnet 3 to move, thus giving a false judgment that the treatment head is sliding close to the skin. That is, it is difficult to accurately determine whether the treatment head is sliding or simply being squeezed by the skin. Therefore, in order to improve the accuracy of the detection results, a gyroscope chip can be added to the treatment head to make a comprehensive judgment on whether the treatment head is sliding from multiple dimensions, so that energy is only output when the treatment head is sliding, thereby avoiding risks such as misjudgment.

[0059] In summary, this application provides a therapeutic device that uses a Hall element to achieve sliding detection. It mainly uses a magnet 3 installed on a diaphragm structure 22 (specifically, the elastic protrusion 222) to achieve sliding detection. When the user slides the therapeutic device, the elastic protrusion 222 on the surface of the treatment head is subjected to the force provided by the skin, causing it to deform. After deformation, the position of the magnet connected to it will move to a certain extent, such as left and right deflection or up and down displacement, thereby causing a change in magnetic flux. After the Hall element 4 detects the change in magnetic flux, it can determine that the treatment head is sliding. At this time, the therapeutic device can be controlled to output energy to achieve the therapeutic effect.

[0060] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
