Description

Technical Field

[0001] The present application relates to the technical field of beauty and physiotherapy equipment, and particularly provides a light therapy device. Background Art

[0002] Currently, on the casings of electronic light therapy products such as light therapy face masks and light therapy devices, components such as a charging structure and a switch button are usually provided. The device is charged through the charging structure, and the on / off of the device is controlled through the switch button. Such a structural design will cause multiple installation slots to be opened on the casing to respectively install the charging structure and the switch button, resulting in a complex overall structure, low assembly efficiency, and affecting the overall aesthetics. Utility Model Content

[0003] The purpose of the embodiments of the present application is to provide a light therapy device, aiming to solve problems such as the complex structure and poor aesthetics of existing light therapy devices.

[0004] To achieve the above purpose, the technical solution adopted in the present application is:

[0048] According to an embodiment of the present application, with reference to Figures 1 - 4 As shown, the phototherapy device provided by the present application includes a housing 28, a phototherapy lamp 31, a positioning part 1, an electrode structure 2, and a circuit board 3. Among them, the housing 28 is provided with a light-transmitting part 30; the phototherapy lamp 31 is arranged in the housing 28 and corresponds to the light-transmitting part 30; the positioning part 1 is arranged on the housing 28, and the positioning part 1 is provided with a receiving cavity 4 and a first positioning hole 5 and a second positioning hole 6 communicating with the receiving cavity 4; the electrode structure 2 is arranged in the receiving cavity 4, and the electrode structure 2 includes a first electrode 7 and a second electrode 8 for charging, one of the first electrode 7 and the second electrode 8 is a positive electrode, and the other is a negative electrode. The first electrode 7 has a first end 9, and the first end 9 of the first electrode 7 is exposed (protruding or flush) from the first positioning hole 5. The second electrode 8 has a second end 10, and the second end 10 of the second electrode 8 is exposed (protruding or flush) from the second positioning hole 6; the circuit board 3 is electrically connected to the phototherapy lamp 31, the first electrode 7, and the second electrode 8, and the circuit board 3 is used to form an electrical conduction path when the first end 9 of the first electrode 7 and the second end 10 of the second electrode 8 are in contact with the skin.

[0049] In this embodiment of the present application, it aims to simplify the design of the phototherapy device and improve the user experience. Specifically:

[0050] The housing 28, as the outer shell of the whole machine, is mainly used to carry each component. The phototherapy lamp 31 is electrically connected to the circuit board 3 and corresponds to the light-transmitting part 30. The phototherapy lamp 31 can emit light outward through the light-transmitting part 30, so as to realize phototherapy.

[0051] The positioning part 1 is provided with a receiving cavity 4 for accommodating the electrode structure 2. The electrode structure 2 includes a first electrode 7 and a second electrode 8. The two electrodes are respectively exposed in the first positioning hole 5 and the second positioning hole 6 of the positioning part 1 through their respective ends (the first end 9 and the second end 10). Such a design allows the two electrodes to contact the positive charging contact 12 and the negative charging contact 13 on the charging base 11 for charging, and also allows the two electrodes to directly contact the user's skin.

[0052] In this embodiment, the circuit board 3 can be disposed in the accommodating cavity 4 of the positioning portion 1. A fixing bracket 14 can be provided at the bottom of the circuit board 3. The circuit board 3 is fixed in the housing 28 through the fixing bracket 14. At this time, the first electrode 7 and the second electrode 8 can be fixed on the circuit board 3. Alternatively, the circuit board 3 is fixed in the housing 28 through the fixing bracket 14. At this time, the first electrode 7 and the second electrode 8 can be fixed on the housing 28 or on structures such as brackets inside the housing 28. The circuit board 3 is electrically connected to the first electrode 7 and the second electrode 8, and is used to detect the contact state between the two electrodes and the skin, and accordingly trigger the on or off operation of the phototherapy device. When the two electrodes are in contact with the skin, a closed circuit is formed, and the circuit board 3 can detect this change and trigger the phototherapy device to turn on.

[0053] Charging process: As Figure 5 shown, when the phototherapy device is placed on the charging base 11, the first electrode 7 and the second electrode 8 are in contact with the positive charging contact 12 and the negative charging contact 13 on the charging base 11 through the first positioning hole 5 and the second positioning hole 6. The charging contacts provide power for the electrodes to achieve charging of the phototherapy device.

[0054] On / Off process: When the user presses the phototherapy device tightly against the skin, the first electrode 7 and the second electrode 8 are in contact with the skin. Since the skin is a conductor, a closed conductive circuit is formed among the two electrodes, the circuit board 3 and the skin. After detecting the signal of this conductive circuit, the circuit board 3 triggers the phototherapy device to turn on and generates an appropriate micro-current between the two electrodes to stimulate the skin to achieve physical therapy.

[0055] When the user removes the phototherapy device from the skin, the circuit is disconnected, and the circuit board 3 detects this change and triggers the device to turn off.

[0056] Therefore, the user can control the on / off of the phototherapy device through simple skin contact, and the operation is more intuitive and convenient.

[0057] The phototherapy device provided by the embodiment of the present application can, on the one hand, achieve the phototherapy function. On the other hand, by integrating the charging and on / off functions into one through the electrode structure 2, the phototherapy device does not require additional switch buttons and installation slots, thereby making the phototherapy device more concise and beautiful, and improving the operation convenience and overall experience of the user.

[0058] According to an embodiment of the present application, referring to Figure 3 and Figure 4As shown, the positioning part 1 can telescopically move relative to the first electrode 7 and the second electrode 8 to switch between a first position and a second position; when the positioning part 1 moves to the first position, the first end 9 of the first electrode 7 and the second end 10 of the second electrode 8 are both built into the accommodating cavity 4; when the positioning part 1 moves to the second position, the first end 9 of the first electrode 7 and the second end 10 of the second electrode 8 are respectively exposed corresponding to the first positioning hole 5 and the second positioning hole 6.

[0059] In this embodiment of the present application, the positioning part 1 is designed to be telescopically movable and can switch between a first position and a second position. In the first position, the first electrode 7 and the second electrode 8 are completely hidden in the accommodating cavity 4 of the positioning part 1 and are not exposed. In the second position, the first end 9 of the first electrode 7 and the second end 10 of the second electrode 8 are respectively exposed in the first positioning hole 5 and the second positioning hole 6 of the positioning part 1 for contacting the skin or charging.

[0060] Power on and off process: When the user presses the light therapy device tightly against the skin, the positioning part 1 moves to the second position under the squeezing force of the skin, so that the first electrode 7 and the second electrode 8 extend out relatively and contact the skin. A closed conductive loop is formed among the two electrodes, the circuit board 3, and the skin. After the circuit board 3 detects the signal of this conductive loop, it triggers the device to power on and generates an appropriate microcurrent between the two electrodes to start stimulating the skin for physical therapy.

[0061] When the user removes the light therapy device from the skin, the positioning part 1 automatically resets to the first position due to the loss of the squeezing force, and the two electrodes retract relatively into the accommodating cavity 4 of the positioning part 1 accordingly. The circuit board 3 detects the disconnection of the loop and triggers the device to power off. Therefore, when the light therapy device is not in use, the electrode structure 2 can be completely hidden inside the positioning part 1, which can prevent the user from accidentally touching the electrode structure 2 and causing the device to power on, and can effectively protect the electrode structure 2 from being damaged, thereby prolonging its service life.

[0062] Charging process: As Figure 5 shown, a groove 15 adapted to the positioning part 1 is provided at the top of the charging base 11, and the positive charging contact 12 and the negative charging contact 13 of the charging base 11 are arranged at the bottom of the groove 15. When the light therapy device is placed on the charging base 11, the positioning part 1 is located in the groove 15 but does not contact the bottom of the groove 15, so it will not be squeezed and moved. At this time, there is no relative position change between the positioning part 1 and the electrode structure 2. The positioning part 1 and the groove 15 cooperate to achieve positioning. The positive charging contact 12 and the negative charging contact 13 of the charging base 11 respectively contact the corresponding first electrode 7 and second electrode 8 through the first positioning hole 5 and the second positioning hole 6 of the positioning part 1 to achieve charging. Such a design can effectively improve the user experience.

[0063] Of course, in some embodiments, the top of the charging base 11 has a planar structure. When the phototherapy device is placed on the charging base 11, the positioning portion 1 contacts the top plane of the charging base 11 and is squeezed and moved. At this time, the first electrode 7 and the second electrode 8 relatively protrude and are exposed in the first positioning hole 5 and the second positioning hole 6 of the positioning portion 1, and contact the positive charging contact 12 and the negative charging contact 13 of the charging base 11 to achieve charging. Such a design can ensure that the electrode structure 2 better contacts the charging contact, improving the charging reliability.

[0064] According to an embodiment of the present application, referring to Figure 1 , Figure 3 and Figure 4 As shown, a slot 29 is provided on the housing 28. The positioning portion 1 includes: a positioning wall 16 and a peripheral wall 17. The positioning wall 16 is provided with a first positioning hole 5 and a second positioning hole 6; the peripheral wall 17 can telescopically move within the slot 29. The peripheral wall 17 is vertically connected to the edge of the positioning wall 16 to construct an accommodation cavity 4, and an opening 18 is provided on one side of the accommodation cavity 4 relative to the positioning wall 16. A circuit board 3 is provided at the opening 18, and the positioning wall 16 can telescopically move in a direction away from or close to the circuit board 3. The circuit board 3 is provided with a first electrode 7 and a second electrode 8.

[0065] Specifically, when the user presses the phototherapy device tightly against the skin, the positioning wall 16 is subjected to a squeezing force and moves close to the circuit board 3 to the second position, so that the first electrode 7 and the second electrode 8 relatively protrude and contact the skin.

[0066] A closed conductive loop is formed among the two electrodes, the circuit board 3 and the skin. After the circuit board 3 detects this change, it triggers the device to turn on, and generates an appropriate microcurrent between the two electrodes to start stimulating the skin for physical therapy.

[0067] When the user moves the device away from the skin, the positioning wall 16 moves away from the circuit board 3 due to the loss of the squeezing force and automatically resets to the first position, and the electrode structure 2 relatively retracts into the accommodation cavity 4 accordingly. The circuit board 3 detects that the loop is disconnected and triggers the device to turn off.

[0068] By arranging the circuit board 3 at the opening 18 of the positioning portion 1 in the embodiment of the present application, the space is effectively utilized, and the overall structure of the device can be made more compact.

[0069] According to an embodiment of the present application, referring to Figure 3 and Figure 4 As shown, an elastic structure 19 is provided between the positioning wall 16 and the circuit board 3. The specific type of the elastic structure 19 in the present application is not particularly limited. For example, it can be components such as a spring or a spring piece.

[0070] In this embodiment of the present application, the positioning wall 16 can telescopically move relative to the circuit board 3. The elastic structure 19 is located between the positioning wall 16 and the circuit board 3. The function of the elastic structure 19 is to help the positioning portion 1 automatically reset to the initial position (the first position) when the positioning wall 16 detaches from the skin or the charging base 11, and hide the electrode structure 2 inside the positioning portion 1. This design ensures that the electrode structure 2 is protected when not in use, and at the same time maintains the cleanliness and beauty of the device.

[0071] Specifically, when the positioning wall 16 is subjected to a squeezing force (such as contacting the skin), the positioning wall 16 will move in the direction close to the circuit board 3, that is, move to the second position, so that the first electrode 7 and the second electrode 8 relatively protrude and contact the skin.

[0072] When the positioning wall 16 detaches from the skin, the restoring force provided by the elastic structure 19 causes the positioning wall 16 to move in the direction away from the circuit board 3, that is, move to the first position, and the electrode structure 2 retracts into the accommodating cavity 4 accordingly.

[0073] Therefore, in the embodiment of the present application, by providing the elastic structure 19 between the positioning wall 16 and the circuit board 3, the automatic reset function of the positioning portion 1 is realized, ensuring that the electrode structure 2 can be safely hidden when not in use. This design not only simplifies the operation of the user, but also enhances the durability and beauty of the product.

[0074] According to an embodiment of the present application, with reference to Figure 3 and Figure 4 As shown, the elastic structure 19 includes: a first connecting portion 20, a second connecting portion 21, and an elastic member 22. The first connecting portion 20 is provided on the positioning wall 16; the second connecting portion 21 is provided on the circuit board 3; and the two ends of the elastic member 22 are respectively connected to the first connecting portion 20 and the second connecting portion 21.

[0075] There is no particular limitation on the specific types of the first connecting portion 20 and the second connecting portion 21 in the present application, as long as they can play a connecting role.

[0076] For example, the first connecting portion 20 and the second connecting portion 21 can be designed as connecting columns. The elastic member 22 is a spring, and the two ends of the spring are respectively sleeved on the two connecting columns.

[0077] For another example, the first connecting portion 20 and the second connecting portion 21 can be designed as clamping members, adhesive members, or welding members, etc. The elastic member 22 is a spring sheet, and the two ends of the spring sheet are respectively connected to the first connecting portion 20 and the second connecting portion 21 by means of clamping, gluing, or welding.

[0078] The elastic structure 19 provided in the embodiment of the present application can ensure the reliability of elastic reset.

[0079] According to an embodiment of the present application, with reference toFigure 3 and Figure 4 As shown in Figure 4 , the number of the elastic structures 19 is at least two groups, and the elastic structures 19 of each group are arranged at intervals.

[0080] For example, the number of the elastic structures 19 is two groups, and the two groups of elastic structures 19 are arranged on the left and right sides of the electrode structure 2.

[0081] Also for example, the number of the elastic structures 19 is at least three groups, and the elastic structures 19 of each group are evenly distributed around the electrode structure 2 along the circumferential direction.

[0082] With such a design, the movement stability of the positioning part 1 can be effectively improved, so as to ensure that the electrode structure 2 can accurately extend into the positioning hole structure, and further ensure the reliability of charging and power on / off.

[0083] According to an embodiment of the present application, with reference to Figure 3 As shown in Figure 3 , a first stop structure 23 is provided on the inner edge of the opening 18 of the positioning part 1, and the first stop structure 23 is arranged on the side of the circuit board 3 facing away from the positioning wall 16.

[0084] For example, the first stop structure 23 includes at least two first stop blocks of a split structure, and the first stop blocks are arranged at intervals along the circumferential direction of the inner edge of the opening 18 of the positioning part 1.

[0085] Also for example, the first stop structure 23 is a first stop ring of an integral structure, and the first stop ring is arranged on the inner edge of the opening 18.

[0086] When the positioning part 1 moves to the initial position (the first position), the first end 9 of the first electrode 7 and the second end 10 of the second electrode 8 are both placed inside the accommodating cavity 4. At this time, the first stop structure 23 can hook the circuit board 3 to prevent the positioning part 1 from falling off the circuit board 3, thereby improving the stability of the phototherapy device.

[0087] According to an embodiment of the present application, with reference to Figure 4 As shown in Figure 4 , a second stop structure 24 is provided on the outer side of the peripheral wall 17 of the positioning part 1, and the second stop structure 24 is arranged in the slot 29 of the housing 28.

[0088] Specifically, as Figure 1 shown in Figure 1 , the housing 28 of the phototherapy device is provided with a slot 29 adapted to the positioning part 1, and the positioning part 1 is arranged in the slot 29.

[0089] The second stop structure 24 includes at least two second stop blocks of a split structure, and the second stop blocks are arranged at intervals along the circumferential direction of the edge of the slot 29 and are clamped in the slot 29.

[0090] Or, the second stop structure 24 is a second stop ring of an integral structure, and the second stop ring is clamped in the slot 29.

[0091] When the positioning portion 1 moves to the initial position (the first position), the first end 9 of the first electrode 7 and the second end 10 of the second electrode 8 are both built into the accommodation cavity 4. At this time, the second stop structure 24 can hook the edge of the slot 29 to prevent the positioning portion 1 from falling off the housing 28, thereby improving the stability of the device.

[0092] According to an embodiment of the present application, with reference to Figure 3 and Figure 4 As shown, a first guide sleeve 25 and a second guide sleeve 26 are provided inside the positioning wall 16. The first guide sleeve 25 communicates with the first positioning hole 5 and is used to guide the first end 9 of the first electrode 7; the second guide sleeve 26 communicates with the second positioning hole 6 and is used to guide the second end 10 of the second electrode 8.

[0093] Specifically, the first end 9 of the first electrode 7 and the second end 10 of the second electrode 8 respectively pass through the first guide sleeve 25 and the second guide sleeve 26 and perform telescopic movement relative to the positioning portion 1.

[0094] When the positioning portion 1 moves to the first position, the first end 9 of the first electrode 7 and the second end 10 of the second electrode 8 are built into the corresponding guide sleeves and are not exposed.

[0095] When the positioning portion 1 moves to the second position, the first end 9 of the first electrode 7 and the second end 10 of the second electrode 8 respectively extend out of the corresponding guide sleeves so as to contact the skin or be charged.

[0096] The embodiment of the present application can ensure the stability of the electrode structure 2 during telescopic movement in the positioning hole structure through the guide sleeve structure, reduce shaking, and ensure the stability and reliability of the device during charging and power-on / off processes. Moreover, the guide sleeve structure enables the electrode structure 2 to telescopically move quickly and smoothly, ensuring that the device can quickly respond to the user's operations. In addition, by guiding the movement of the electrode structure 2 through the guide sleeve structure, the friction between the electrode structure 2 and the positioning wall 16 can be reduced, wear can be reduced, and the service life of the device can be extended.

[0097] According to an embodiment of the present application, with reference to Figure 3 and Figure 4 As shown, caps 27 are provided in both the first positioning hole 5 and the second positioning hole 6, and the caps 27 are detachably connected or movably connected to the positioning portion 1.

[0098] In this embodiment of the present application, the cap 27 can be a detachable split structure with the positioning portion 1, or can be movably connected to the edge of the corresponding positioning hole through a flexible band or a pin shaft. When the device needs to be used, the cap 27 can be removed or opened, and when not in use, the cap 27 can be covered to protect the electrode structure.

[0099] Specifically, the detachable cap 27 is independent of the positioning part 1. When the device needs to be used, the cap 27 is manually removed. When not in use, the cap 27 is manually put on to protect the electrode structure 2.

[0100] The movably connected cap 27 is movably connected to the edge of the positioning hole through a flexible band (such as a plastic band or a rubber band) or a pin shaft. When the device needs to be used, the cap 27 is flipped open so as not to affect the protrusion of the electrode structure 2. When not in use, the cap 27 is directly put on to protect the electrode structure 2. At the same time, this movably connected design can prevent the loss of the cap 27 and improve the overall durability of the device.

[0101] Therefore, in the embodiment of the present application, the electrode structure 2 can be effectively protected from dust and impurities by the cap 27, and the service life of the device is prolonged.
