Description

Technical field

[0001] The utility model belongs to the technical field of skin treatment instruments, in particular to an ultraviolet light therapy instrument with a skin detection device. [Background Technology]

[0002] Ultraviolet light therapy is a medical device that uses ultraviolet radiation to treat skin diseases. It works by irradiating the skin with ultraviolet light of a specific wavelength, stimulating the metabolic activity of skin cells and enhancing immunity, thereby achieving the desired effect.

[0003] In order to improve the safety of ultraviolet light therapy devices, patent CN219896806U in the prior art discloses a light therapy device with a safety device, which has a contact induction coil arranged around the light outlet, and controls the light output by detecting whether there is contact with the patient's skin through the contact induction coil, thereby achieving the purpose of safety control; however, the light therapy device is only suitable for skin treatment of patient areas with high flatness, and is not suitable for areas with obvious concave and convex features, small curved surface areas or situations where the patient area is at some edge positions, such as fingers, toes, cheek and jaw edges, etc. When the light outlet of the light therapy device cannot fully fit the skin and can only partially fit the skin, if the above-mentioned light therapy device is used for treatment, the light output will stop or will not be output because the light outlet does not fully fit the skin, resulting in the treatment process being often interrupted or even unable to perform light therapy normally.

[0004] Therefore, it is necessary to provide a new ultraviolet light therapy device with a skin detection device to solve the above technical problems. [Utility Model Content]

[0005] The main purpose of this utility model is to provide an ultraviolet light therapy device with a skin detection device, which takes the particularity of the patient's location into consideration, provides a basis for flexible control for skin fit monitoring, and improves the treatment smoothness and stability of the light therapy device while ensuring safety.

[0006] The present invention achieves the above-mentioned purpose through the following technical solution: an ultraviolet light therapy device with a skin detection device, which includes a shell provided with a light outlet and a skin sensing unit arranged around the light outlet, the skin sensing unit including at least two sensing modules spaced around the light outlet and a control module electrically connected to the sensing modules and controlling the light emission of the light therapy device according to set rules.

[0007] Furthermore, the setting rule is one of the two modes selected by the user from the full control mode and the non-full control mode. The full control mode is configured to emit light only when all the sensing modules sense that the skin is touching, and the non-full control mode is configured to emit light only when the number of sensing modules that sense that the skin is touching reaches a set number.

[0008] Furthermore, the setting rule is one of a full control mode and a non-full control mode. The full control mode is configured to emit light only when all the sensing modules sense that skin is touching. The non-full control mode is configured to emit light only when a set number of the sensing modules sense that skin is touching is reached.

[0009] Furthermore, it also includes a main control board arranged in the shell; the control module is separately arranged in the shell and electrically connected to the main control board, or is integrated on the main control board.

[0010] Furthermore, a skin-fitting surface distributed around the light outlet is formed on the surface of the housing, and a sensing plane formed by the sensing module is parallel and located below the skin-fitting surface.

[0011] Furthermore, the sensing module is a capacitive sensor.

[0012] Furthermore, it also includes a light-emitting component and a heat sink arranged in the shell, and a filter arranged at the light outlet. The heat sink has a mounting platform, the light-emitting component is arranged on the mounting platform and the light-emitting end is aligned with the light outlet, and the light-emitting component is electrically connected to the main control board.

[0013] Furthermore, a sensor support member conforming to the outline of the light outlet is provided on the installation platform, and the sensing modules are arranged at intervals along the outline of the upper surface of the sensor support member.

[0014] Furthermore, the sensing module is arranged to fit the inner surface of the filter.

[0015] Furthermore, the sensing module is arranged to fit the inner wall surface of the shell.

[0016] Furthermore, the housing is provided with a display panel, a start button, a function adjustment button and a power interface electrically connected to the main control board.

[0017] Compared with the prior art, the beneficial effect of the ultraviolet light therapy device with a skin detection device of the present invention is that it takes the special characteristics of the patient's position into consideration to perform safety control of skin adhesion, thereby improving the treatment smoothness and use stability of the light therapy device while ensuring safety. Specifically, a plurality of sensing modules are arranged at intervals around the light outlet, and a distributed sensing module is used to monitor the skin adhesion status at multiple monitoring positions, laying the foundation for realizing a non-full control safety mode; when the patient's affected area is located in a relatively flat large skin area, in order to improve safety, the full control mode can be turned on. In this mode, the light-emitting component will only emit light when all the sensing modules detect that the skin is adhered; if the patient's affected area is in a special position and cannot be completely adhered to the area around the light outlet, the non-full control mode can be turned on. In this mode, the light-emitting component will only emit light when one or a set number of sensing modules detect that the skin is adhered, so that the light therapy device of this scheme is suitable for more usage scenarios while improving user safety.

[0028] Example 1:

[0029] Please refer to Figure 1-Figure 7 This embodiment is a UV light therapy device 100 with a skin detection device, which includes a housing 1 with a light outlet 11, a skin sensing unit 2 disposed around the light outlet 11, a main control board 3 disposed within the housing 1, a fan 8, a heat sink 5, a battery 9, and a light-emitting component 4 disposed on the heat sink 5 and aligned with the light outlet 11. The light-emitting component 4, the skin sensing unit 2, and the fan 8 are all electrically connected to the main control board 3.

[0030] An installation cavity 13 is formed inside the housing 1. The main control board 3 is arranged in a vertical standing posture in the installation cavity 13. The fan 8 is arranged above the main control board 3 in a lying state. The radiator 5 is arranged above the fan 8 and has a mounting platform 51 on the top. The light-emitting component 4 is arranged on the mounting platform 51. The heat generated by the light-emitting component 4 is conducted through the radiator 5 and then dissipated by the fan 8, thereby reducing the temperature around the light outlet 11 and preventing the light-emitting component 4 from generating high temperature and scalding the user's skin due to long-term heating. The battery 9 is fixed to the housing 1 by gluing to power the ultraviolet light therapy device. In other embodiments, the battery 9 may not be configured, and an adapter may be used to connect the power supply for power supply.

[0031] The housing 1 is provided with a display panel 14, a start button 15, a function adjustment button 16 and a power interface 17 electrically connected to the main control board 3. The display panel 14 realizes the display of the human-computer interaction interface, and the start button 15 is used to turn on or off the ultraviolet light therapy device. The function adjustment button 16 is configured to adjust parameters such as light intensity and light therapy time. The power interface 17 can be used to realize data connection with the host computer and serve as a power supply and charging interface. In other embodiments, the function adjustment button 16 can also be designed in the form of a touch button in the display interface of the display panel 14.

[0032] The outer surface of the housing 1 is also provided with a plurality of air flow holes connected to the mounting cavity 13, which facilitates the rapid dissipation of heat in the mounting cavity 13 and improves the heat dissipation efficiency. The air flow holes include a plurality of air outlets 19 and air inlets 18, such as Figure 2 As shown, the multiple rows of circular holes near the lower side on the surface of one side of the shell 1 are air inlets 18, and the multiple rows of circular holes near the upper side are air outlets 19. Cold air enters the installation cavity 13 from the air inlet 18, is drawn out by the fan 8 and blown toward the radiator 5, and then takes away the heat on the radiator 5 and is discharged through the air outlet 19.

[0033] The skin sensing unit 2 includes at least two sensing modules 21 spaced apart around the light outlet 11 and a control module 22 electrically connected to the sensing modules 21 and controlling the light emission of the phototherapy device according to a set rule. The set rule can be one of a full control mode and a non-full control mode, which is directly defaulted to the full control mode or the non-full control mode in the control module 22; or both full control mode and non-full control mode can be provided for selection, and the user sets the set rule to one of them according to their own usage needs. The full control mode is when all the sensing modules 21 sense that there is skin contact, and the non-full control mode is when the number of sensing modules 21 sensing that there is skin contact, reaches a set number, and emits light. The sensing modules 21 can be set to 2, 3, 4 or more.

[0034] The housing 1 has a skin-contacting surface 12 formed on its surface, surrounding the light outlet 11 and parallel to the sensing module 21. The sensing module 21 is a capacitive sensor, forming one electrode of a capacitor. When the skin-contacting surface 12 is in close contact with human skin, the skin forms the other electrode of the capacitor, causing a capacitance change on the sensing module 21. By monitoring this capacitance change, the presence of the skin-contacting surface 12 in contact with the skin can be detected, thus implementing a skin contact monitoring function.

[0035] The control module 22 can be directly integrated on the main control board 3 ; or it can be separately provided in the installation cavity 13 as a control circuit board and electrically connected to the main control board 3 .

[0036] The control module 22 detects whether the skin-fitting surface 12 is tightly fitted to the skin through the sensing module 21. The control module 22 has a number of signal input channels corresponding to the sensing module 21. It is responsible for digitizing the input skin-sensing signals, determining whether each skin-sensing signal has skin contact, and outputting a total output signal I to determine whether the phototherapy device can emit light. The main control board 1 controls whether the light-emitting component 4 emits light based on the total output signal I. The control module 22 has two working modes:

[0037] (1) Full control mode: In this mode, the light emitting component 4 emits light only when all the sensing modules 21 detect skin contact;

[0038] (2) Non-full control mode: In this mode, the light emitting component 4 emits light only when one or a set number of sensing modules 21 detects skin contact.

[0039] This embodiment further includes a filter 6 disposed at the light outlet 11 , which protects the light emitting component 4 on the one hand and allows the ultraviolet light emitted by the light emitting component 4 to pass through on the other hand.

[0040] In this embodiment, the optical filter 6 is disposed on a filter mounting seat 61 and is fixed by pressing the housing 1. In other embodiments, the optical filter 6 can also be directly mounted on the light outlet 11 by means of mounting buckles.

[0041] In this embodiment, a sensor support member 7 is provided on the mounting platform 51, enclosing the light-emitting assembly 4 and conforming to the shape of the light outlet 11. The sensing modules 21 are spaced apart along the contour of the upper surface of the sensor support member 7. In other embodiments, the sensing modules 21 may also be mounted on the filter mounting seat 61 and secured by pressure against the lower surface of the filter 6; or they may be directly adhered to the inner surface of the filter 6, adhered to the outer surface of the filter 6 and secured by pressure against the inner wall of the housing 1, or directly adhered to the inner wall of the housing 1.

[0042] The light-emitting component 4 is primarily used to emit ultraviolet light and can be secured to the mounting platform 51 by gluing, screwing, or snapping. Thermal grease is applied to the interface between the light-emitting component 4 and the mounting platform 51 to improve heat conduction. The sensing module 21 is secured to the sensor support 7, which is made of insulating and heat-isolating material, isolating the sensing module 21 from the heat sink 5. The wires connecting the sensing module 21 to the control module 22 are also isolated from the heat sink 5, for example, by physical isolation or by wrapping an insulating material layer around the wires. This reduces interference from the heat sink 5 on the skin sensing unit 2, thereby improving the accuracy of the skin sensing module 21 in monitoring skin contact.

[0043] The main control board 3 is provided with a parameter setting module, which is used in conjunction with the display panel 14 to set the working mode of the control module 22 .

[0044] This embodiment further includes a cap 10 that is buckled onto the light outlet 11 of the housing 1. When not in use, the cap 10 is covered to protect the light outlet 11.

[0045] For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
