[0036] The utility model provides a treatment head 100 .

[0037] Please refer to Figures 1 to 3 In some embodiments of the utility model treatment head 100, the treatment head 100 includes:

[0038] The housing 10 has a treatment surface 11 for contacting the part to be treated 200. An accommodating space is formed in the housing 10. The treatment surface 11 has an opening 111 communicating with the accommodating space.

[0039] The treatment component 30 is disposed in the accommodating space and partially exposed in the opening 111, and is used to contact the part to be treated 200. At least a part of the outer wall of the treatment component 30 and the inner wall of the housing 10 are spaced apart to enclose an installation space communicating with the opening 111; and

[0040] The detection component 20 is disposed in the installation space and is arranged toward the opening 111 to detect the fit between the treatment surface 11 and the part to be treated 200 through the opening 111 .

[0041] The part to be treated 200 may be human skin, and the treatment surface 11 of the housing 10 is used to contact and fit the part to be treated 200. A housing space for accommodating the treatment component 30 and the detection component 20 is formed in the housing 10, and an opening 111 communicating with the housing space is provided on the treatment surface 11 of the housing 10, so that the treatment component 30 in the housing space can be at least partially exposed to the opening 111, so as to contact the part to be treated 200 through the opening 111 for treatment. In addition, the entire outer wall of the treatment component 30 may be spaced apart from the inner wall of the housing 10, or at least part of the outer wall of the treatment component 30 may be spaced apart from the inner wall of the housing space by means of, but not limited to, providing an installation groove 31 on the outer wall of one end of the treatment component 30 facing the opening 111, so that an installation space communicating with the opening 111 can be formed by enclosing the outer wall of the treatment component 30 and the inner wall of the housing 10 for installing the detection component 20.

[0042] In some embodiments, the detection component 20 can realize contact detection through the light sensor 21 in the embodiment described later, that is, the light sensor 21 detects the brightness value of the opening 111 to determine the shielding condition at the opening 111, and then determines whether the treatment surface 11 forms good contact with the part to be treated 200; the detection component 20 can also, but is not limited to, determine whether there is a part to be treated 200 at the opening 111 through other non-contact sensors such as capacitive sensors or infrared sensors to determine whether good contact is formed with the part to be treated 200. The specific implementation method can be set according to actual needs and is not limited here.

[0043] It should be noted that in the related art, the treatment device, such as the treatment head 100 of the ultrasonic treatment device, often realizes contact detection by setting a pressure sensor, which is used to detect the fit between the treatment head 100 and the part to be treated 200 of the human skin, so as to ensure that the treatment device can start working after it is in close contact with the skin. Among them, the pressure sensor is generally set at the treatment surface 11 of the treatment head 100 for contacting the part to be treated 200. During the detection, it is necessary to press the skin with a certain pressure to realize the contact detection; in addition, affected by the sensitivity of the pressure sensor, even if the treatment head is in close contact with the skin, the pressure does not reach the detection threshold of the pressure sensor, which may cause the treatment device to fail to start, affecting the user experience.

[0044] Therefore, it can be understood that, in the technical solution of the present utility model, the treatment head 100 includes a shell 10 and a treatment component 30 arranged in the shell 10, wherein a housing space with an opening 111 at one end is formed in the shell 10, and at least part of the outer wall of the treatment component 30 and the inner wall of the housing space are arranged at intervals to enclose and form an installation space connected to the opening 111. The detection component 20 is arranged in the installation space and is arranged toward the opening 111, and can detect whether there is a part to be treated 200 at the opening 111, so as to detect the fit between the treatment surface 11 and the part to be treated 200. In this way, compared with the technical solution of setting a pressure sensor in the related art, since the detection component 20 of this solution does not need to press the skin with a certain pressure to complete the detection, the treatment head 100 only needs to make the treatment surface 11 of its shell 10 and the part to be treated complete fit to perform treatment when in use, thereby avoiding the situation where the treatment device cannot be started due to the pressure not reaching the detection threshold of the pressure sensor, thereby improving the user experience. In addition, it should be noted that, since pressure sensing detection requires a larger treatment area, the treatment head 100 in the related art also has the problem of a larger size at the treatment surface 11, which is not conducive to realizing a miniaturized design of the treatment head 100. Therefore, the technical solution of the present utility model realizes contact detection by adopting a non-pressure sensing detection method, and the detection component 20 can be arranged inside the housing 10, without having to arrange the detection component 20 on the treatment surface 11, so that it does not need to occupy a larger size of the treatment surface 11, which is conducive to realizing a miniaturized design of the treatment head 100.

[0045] Please refer to Figure 1 and Figure 2 In some embodiments of the utility model treatment head 100 , the detection component 20 includes a light sensor 21 . The light sensor 21 is disposed in the installation space and is arranged opposite to the opening 111 for detecting the brightness value of the opening 111 .

[0046] In this embodiment, an opening 111 is set on the treatment surface 11 of the shell 10, and the outer wall of the treatment component 30 and the inner wall of the shell 10 are enclosed to form an installation space connected to the opening 111, so that external light can enter the installation space through the opening 111, and a light sensor 21 is provided in the installation space. With such a configuration, the brightness value at the opening 111 can be detected by the light sensor 21. When external light can normally enter the installation space through the opening 111, the brightness value detected by the light sensor 21 is greater than the preset value. At this time, it can be determined that the treatment surface 11 of the treatment head 100 is not in contact with the part to be treated 200; when the treatment surface 11 of the treatment head 100 is in contact with the part to be treated 200, the part to be treated 200 can block the opening 111 to prevent external light from entering the installation space. When the brightness value of the opening 111 detected by the light sensor 21 is lower than the preset value, it can be determined that the treatment surface 11 of the treatment head 100 has been in contact with the part to be treated 200. In this way, the treatment head 100 does not need to press the skin with a certain pressure during detection to achieve contact detection, thereby improving the user experience.

[0047] Please refer to Figures 1 to 3 In some embodiments of the utility model treatment head 100, the detection component 20 includes:

[0048] A main board 22, which is disposed in the accommodating space and spaced apart on a side of the light sensor 21 facing away from the opening 111; and

[0049] The adapter circuit board 23 is arranged in the accommodating space, and the two ends of the adapter circuit board 23 are electrically connected to the main board 22 and the adapter circuit board 23 respectively, and are used to transmit the light signal generated by the light sensor 21 to the main board 22, so that the main board 22 obtains the fit between the treatment surface 11 and the part to be treated 200 according to the light signal.

[0050] In this embodiment, by setting the main board 22 at the end of the light sensor 21 facing away from the outlet 111 and connecting the main board 22 and the light sensor 21 via the adapter circuit board 23, it is helpful to reduce the occupied volume of the treatment head 100 at the end close to the treatment surface 11.

[0051] In some embodiments, the main board 22 can also be electrically connected to the control unit of the treatment component 30. In this way, when the detection component 20 detects that the treatment surface 11 of the shell 10 has formed a good fit with the part to be treated 200, a treatment signal can be sent to the control unit of the treatment component 30 through the main board 22, so that the treatment component 30 can treat the part to be treated 200 through the opening 111.

[0052] Please refer to Figures 1 to 3In some embodiments of the utility model treatment head 100, the light sensor 21 is arranged at one end of the treatment component 30 facing the opening 111, the main board 22 is arranged at one end of the treatment component 30 away from the opening 111, and the adapter circuit board 23 is arranged on the peripheral side of the treatment component 30.

[0053] The adapter circuit board 23 can be configured as a flexible circuit board, so that the adapter circuit board 23 can be easily attached to the outer wall of the treatment component 30 to improve the structural compactness of the treatment head 100. Furthermore, the outer wall of the treatment component 30 can also be provided with a groove to limit the flexible circuit board, so that the installation stability of the flexible circuit board can be improved.

[0054] Please refer to Figures 1 to 3 In some embodiments of the utility model treatment head 100, the outer wall of the treatment component 30 facing the opening 111 is provided with a mounting groove 31, and the groove wall of the mounting groove 31 and the inner wall of the housing 10 enclose a mounting space. This is conducive to improving the installation stability of the light sensor 21, so as to ensure that the light sensor 21 can stably perform detection work.

[0055] Please refer to Figure 1 and Figure 2 In some embodiments of the utility model treatment head 100, the outer wall of the treatment component 30 is provided with one of the limit block 12 and the limit groove 32, and the inner wall of the shell 10 is provided with the other of the limit block 12 and the limit groove 32, and the limit groove 32 and the limit block 12 are plugged into each other.

[0056] In this way, the structural stability between the shell 10 and the treatment component 30 can be improved, the risk of displacement of the treatment component 30 can be reduced, and it is beneficial to achieve close fit of the various components of the treatment head 100.

[0057] Please refer to Figures 1 to 3 In some embodiments of the utility model treatment head 100 , the treatment head 100 further includes a light guide column 40 . The light guide column 40 is disposed in the installation space and is located at one end of the light sensor 21 facing the opening 111 .

[0058] In this embodiment, the light guide column 40 serves as a transmission medium for light, and external light can be transmitted to the light sensor 21 through the light guide column 40 , which is beneficial for the light sensor 21 to accurately detect the brightness value at the opening 111 .

[0059] Furthermore, in some embodiments, the end face of the light guide column 40 facing away from the light sensor 21 is flush with the outer end face of the treatment surface 11 of the shell 10. In this way, the light guide column 40 can better transmit external natural light into the shell 10 to facilitate detection by the light sensor 21, while avoiding the light guide column 40 protruding from the treatment surface 11 and affecting the fit between the treatment surface 11 and the part to be treated 200. This is beneficial to improving the detection accuracy of the detection component 20.

[0060] Similarly, in some embodiments, one end of the light guide column 40 facing the light sensor 21 is arranged in close contact with the light sensor 21. In this way, the light guide column 40 can better transmit the optical fiber to the light sensor 21, which is also beneficial to improving the detection accuracy of the detection component 20 to achieve a better contact detection effect.

[0061] Please refer to Figures 1 to 3 In some embodiments of the utility model treatment head 100, a plurality of light sensors 21 are provided, and the plurality of light sensors 21 are sequentially spaced along the circumference of the treatment component 30;

[0062] There are a plurality of light guide rods 40 , and each light guide rod 40 is disposed corresponding to a light sensor 21 .

[0063] The provision of a plurality of light sensors 21 is helpful to improve the detection accuracy of the brightness value at the opening 111 , so as to better detect whether the treatment surface 11 of the treatment head 100 is in contact with the part to be treated 200 .

[0064] Among them, the end of the adapter circuit board 23 away from the main board 22 can be arranged in an annular belt structure, so that a plurality of light sensors 21 can be arranged in sequence along the circumference of the annular belt and electrically connected to the adapter circuit board 23, so that multiple light sensors 21 can be easily installed.

[0065] In some embodiments of the utility model treatment head 100, the treatment head 100 further includes an environment detection component 20 for detecting an environment brightness value.

[0066] Since the treatment head 100 cannot effectively detect whether its treatment surface 11 is in contact with the treated part 200 through the light sensor 21 in an environment with very low ambient brightness or in complete darkness, an environment detection component 20 for detecting the ambient brightness value is provided to prompt the user whether the current use environment is suitable, so that the user can use the treatment head 100 in a suitable use environment to avoid misdetection of the treatment head 100.

[0067] It should be noted that, when the treatment head 100 is in an environment with high ambient brightness, after the treatment surface 11 and the part to be treated are fitted, a small amount of ambient light may pass through the tiny gap between the part to be treated and the treatment surface 11, pass through the opening and enter the housing 10, and be detected by the light sensor 21 of the detection component 20. At this time, there is a risk that the detection component 20 mistakenly detects that the treatment surface 11 is not in contact with the part to be treated 200, resulting in the treatment head 100 being unable to start normally. To this end, in some embodiments, the treatment head 100 can simultaneously obtain the brightness value and the ambient brightness value at the opening of the treatment surface 11 of the current use environment by setting the detection component 20 and the environmental detection component in the aforementioned embodiment, and compare the brightness value at the opening of the treatment surface 11 of the current use environment with the ambient brightness value to obtain the difference between the brightness value at the opening of the treatment surface 11 and the ambient brightness value. In this way, the shielding condition at the opening 111 can be judged by the aforementioned brightness value difference, and then the fitting condition of the treatment surface 11 and the part to be treated can be judged.

[0068] Specifically, when the brightness value difference between the brightness value at the opening of the treatment surface 11 and the ambient brightness value is less than a preset value, it can be determined that a certain amount of ambient light still enters the shell 10 through the opening 111, that is, the treatment surface 11 of the treatment head 100 does not form a good fit with the part to be treated 200; when the brightness value difference is greater than the preset value, it can be determined that only a small amount of ambient light can enter the shell 10 through the opening 111, that is, the treatment surface 11 of the treatment head 100 has formed a fit with the part to be treated 200 and is shielded by the opening, and the treatment head 100 can be started normally according to the detection result to perform treatment. Therefore, it can be understood that the technical solution of the utility model, by setting an environmental detection component, can also realize the difference comparison function between the brightness value at the opening of the treatment surface 11 and the ambient brightness value, so that the measurement accuracy of the treatment head 100 can be improved by comparing the brightness value difference.

[0069] Furthermore, the environment detection component 20 can be a light sensor 21 directly arranged on the outer wall of the shell 10, so as to directly detect the ambient brightness value by making its detection end directly contact the use environment; the environment detection component 20 can also be a light sensor 21 arranged in the shell 10, and the part of the shell 10 corresponding to the detection end of the environment detection component 20 can be arranged to be light-transmissive; of course, the environment detection component 20 can also be separated from the shell 10 and arranged on an external structure. For example, the ambient light brightness can be tested through external devices such as smart phones. The specific implementation method can be set according to actual needs and is not limited here.

[0070] Please refer to Figures 1 to 3 In some embodiments of the utility model treatment head 100 , the cross-sectional area of ​​the shell 10 is gradually reduced in the direction toward the treatment surface 11 .

[0071] This helps to reduce the volume occupied by the treatment head 100 at the end close to the treatment surface 11, and can be adapted to the arrangement of the main board 22 and the adapter circuit board 23 at the end of the light sensor 21 facing away from the outlet 111 in the aforementioned embodiment.

[0072] In some embodiments, the cross-sectional area of ​​the treatment component 30 is also gradually reduced in the direction toward the treatment surface 11, so that its outer contour can be contoured with the shell 10, thereby facilitating the limiting fit of the outer wall of the treatment component 30 and the inner wall of the shell 10.

[0073] The utility model also provides a therapeutic device, which includes the therapeutic head 100 in any of the aforementioned embodiments, and the specific structure of the therapeutic head 100 refers to any of the aforementioned embodiments. Since the therapeutic device proposed in this application can apply all the technical solutions in all the aforementioned embodiments, it at least has all the beneficial effects brought by the aforementioned technical solutions, which will not be described one by one here.

[0074] Among them, the therapeutic device can be specifically set as an ultrasonic therapeutic device, which is used to apply ultrasonic energy to the subcutaneous dermis, fat, and fascia layers to achieve lifting and tightening through thermal effects. The treatment head 100 is located at the head of the ultrasonic therapeutic device to ensure that the ultrasonic therapeutic device starts working after it meets the state of fitting the human skin, so as to ensure the therapeutic effect of the ultrasonic therapeutic device. Of course, the technical solution of the utility model is not limited to this. In some embodiments, the therapeutic device can also be set as other types of therapeutic devices according to actual needs, which is not limited here.

[0075] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
