DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Please refer to Figure 1-Figure 3 , Figure 1Schematic diagram of the assembly structure of a liquid supply head. Figure 2 for Figure 1 The schematic diagram of the exploded structure of the liquid supply head shown in FIG. Figure 3 for Figure 1 Schematic diagram of the inner support structure of the liquid supply head shown.

[0030] The utility model provides a liquid supply head 100, which includes a main body 10, a phototherapy lamp board 20 and a connecting part 30. The main body 10 is provided with a storage cavity 1011 and a liquid outlet 1041 connected to the storage cavity 1011. Part of the main body 10 is set as a light-transmitting area 103; the phototherapy lamp board 20 is located in the storage cavity 1011 and is arranged facing the light-transmitting area 103; the connecting part 30 is provided with a liquid channel 3021 (such as Figure 4 As shown), one end of the liquid channel 3021 can be connected to the liquid outlet 1041, and the other end of the liquid channel 3021 is used to connect to the liquid container. The connecting part 30 is rotatably connected to the main body 10 to change the connecting area between the liquid channel 3021 and the liquid outlet 1041 during rotation.

[0031] It should be noted that the main body 10 is the working structure of the liquid supply head 100, which has phototherapy and cleansing functions. The main body 10 is provided with a storage cavity 1011 and a liquid outlet 1041 connected to the storage cavity 1011, and a part of the position is set as a light-transmitting area 103. The light-transmitting area 103 allows light to pass through, and combined with the design of the phototherapy lamp board 20, the phototherapy function is realized. It can be understood that the light-transmitting area 103 can be a light-emitting cover 103 that is separately arranged, or a light-transmitting area 103 formed by openings or other forms such as thin walls, and other areas of the main body 10 are set as non-light-transmitting structures.

[0032] The phototherapy lamp panel 20 is installed in the storage cavity 1011 and is arranged facing the light-transmitting area 103, ensuring that the phototherapy light can effectively irradiate the part that needs to be treated through the light-transmitting area 103 to achieve the phototherapy function.

[0033] The connecting portion 30 is provided with a liquid channel 3021, one end of which is connected to the liquid outlet 1041, and the other end is used to connect to the liquid container. Therefore, the liquid in the liquid container can enter the liquid outlet 1041 along the liquid channel 3021, and flow out from the liquid outlet 1041 for use by the user. The connecting portion 30 is rotatably connected to the main body 10, and the connecting area between the liquid channel 3021 and the liquid outlet 1041 can be changed by rotation, so as to accurately control the liquid flow rate, thereby increasing the convenience of operation of the liquid supply head 100.

[0034] The change of the connection area between the liquid channel 3021 and the liquid outlet 1041 herein includes that the liquid channel 3021 and the liquid outlet 1041 are completely offset, so that the liquid supply head 100 cannot discharge liquid; it also includes that the liquid channel 3021 and the liquid outlet 1041 are completely aligned, at which time the liquid output of the liquid supply head 100 can reach a maximum; it also includes that a part of the liquid channel 3021 is connected to the liquid outlet 1041, and the other part is disconnected from the liquid outlet 1041, at which time the liquid output is between the maximum and minimum.

[0035] The liquid container may be a container containing various liquids such as facial cleanser, shower gel, essence, etc. There is no specific limitation and the user may choose according to actual conditions.

[0036] The technical solution in the embodiment of the present application realizes an integrated design by combining the liquid supply function with the phototherapy function of the liquid supply head 100, thereby increasing the functionality and application range of the liquid supply head 100. The liquid flow rate is precisely controlled by the adjustable connection area between the liquid channel 3021 and the liquid outlet 1041, thereby improving the convenience of use. The rotating connection design of the main body 10 and the connecting part 30 allows the user to easily adjust the liquid flow rate, thereby enhancing the user experience.

[0037] Specifically, the main body 10 includes an outer shell 101 and an inner bracket 102, the outer shell 101 has a storage cavity 1011 and a liquid outlet 1041, the inner bracket 102 is located in the storage cavity 1011 and fixed relative to the outer shell 101, and the inner bracket 102 is formed with a rotation hole 1022 and a connecting channel 1021, one end of the connecting channel 1021 is connected to the rotation hole 1022, and the other end of the connecting channel 1021 is connected to the liquid outlet 1041. The inner bracket 102 is provided with a liquid outlet 1024 for outputting liquid.

[0038] The outer shell 101 is the external structure of the liquid supply head 100, and its size is adapted to the inner bracket 102. The outer shell 101 protects the inner bracket 102 and improves the overall stability and aesthetics of the inner bracket 102. The inner bracket 102 is fixed relative to the outer shell 101, ensuring the stability of each component in the storage cavity 1011 and preventing the internal components from loosening. Of course, the space in the outer shell 101 can also be much larger than the inner bracket 102.

[0039] The inner bracket 102 supports and fixes the components of the liquid supply head 100 . The independent design of the inner bracket 102 and the outer shell 101 makes the maintenance and cleaning of the liquid supply head 100 more convenient, and also reduces the difficulty of processing each part of the structure.

[0040] In this embodiment, the design of the rotating hole 1022 allows the connecting portion 30 to rotate freely in the inner bracket 102, thereby adjusting the communication area between the connecting channel 1021 and the liquid outlet 1041 to achieve precise control of the liquid flow rate.

[0041] It should be noted that the fixed inner bracket 102 and the rotating connecting portion 30 are used to make the operation easier when adjusting the liquid flow rate, without the need to disassemble or reassemble components.

[0042] The main body 10 further includes a connecting ring 307 . The lower end of the housing 101 is fixed to the connecting ring 307 . The base 301 is sealedly sleeved with the connecting ring 307 via a sealing ring 40 . The base 301 can rotate relative to the sealing ring 40 and the connecting ring 307 .

[0043] Please refer to Figure 4 and Figure 5 Specifically, the connecting portion 30 includes a base 301 and a connecting protrusion 302 protruding from the base 301 , the liquid channel 3021 passes through the connecting protrusion 302 , and the connecting protrusion 302 rotates with the rotating hole 1022 to change the connecting area between the liquid channel 3021 and the connecting channel 1021 .

[0044] The base 301 is the basic part of the connection part 30, providing a stable support. The connection protrusion 302 is a protruding part protruding from the base 301, and is penetrated by a liquid channel 3021. The connection protrusion 302 is inserted into the rotation hole 1022 of the inner bracket 102, and rotates with it to achieve positioning installation.

[0045] The liquid channel 3021 passes through the connecting protrusion 302, allowing the liquid from the liquid container to sequentially pass through the liquid channel 3021 and the connecting channel 1021 to reach the liquid outlet 1041. By rotating the connecting protrusion 302, the connecting area between the liquid channel 3021 and the connecting channel 1021 can be changed, thereby adjusting the liquid flow rate.

[0046] At least a portion of the connecting protrusion 302 is configured as a non-circular structure, and the rotating hole 1022 is a circular hole, so a larger gap can be formed between the non-circular portion of the connecting protrusion 302 and the hole wall of the rotating hole 1022, which is conducive to the rotation of the connecting protrusion 302 in the rotating hole 1022, and reduces the resistance during rotation. Specifically, a portion of the circumference of the connecting protrusion 302 can be circular, and another portion of the circumference is a concave structure.

[0047] Please refer to Figure 4 and Figure 6 Specifically, the liquid supply head 100 also includes a sealing gasket 90, which is clamped between the end of the connecting protrusion 302 that is away from the base 301 and the inner bracket 102. The sealing gasket 90 is provided with a connecting port 901 corresponding to the connecting channel 1021, and the liquid channel 3021 is connected to the connecting channel 1021 through the connecting port 901.

[0048] The sealing gasket 90 is arranged in the rotating hole 1022, and can seal the gap between the connecting protrusion 302 and the top hole wall of the rotating hole 1022 to prevent leakage. At the same time, since the connecting protrusion 302 contacts the inner bracket 102 through the sealing gasket 90, the sealing gasket 90 is relatively soft, which avoids the sealing gasket 90 from directly contacting the inner bracket 102, thereby avoiding direct friction between the two relatively hard parts, and improving the durability of the liquid supply head 100.

[0049] Please refer to Figure 3 and Figure 6 Specifically, the inner bracket 102 is further provided with an anti-rotation protrusion 1023, and the sealing gasket 90 is provided with an anti-rotation groove 902 to be plugged with the anti-rotation protrusion 1023. The plug-in design of the anti-rotation protrusion 1023 and the anti-rotation groove 902 prevents the sealing gasket 90 from being driven by the connecting part 30 to rotate together.

[0050] Please refer to it again Figure 2 Specifically, the liquid supply head 100 also includes a circuit board 50 and a battery 60. The circuit board 50, the battery 60 and the phototherapy lamp board 20 are electrically connected and are all fixed to the inner bracket 102; the circuit board 50 is provided with a vibrator 501.

[0051] It should be noted that the circuit board 50 can accurately control the working status and parameters of the phototherapy lamp board 20 and the vibrator 501 to achieve intelligent operation.

[0052] Please refer to Figures 7 to 9 Specifically, one of the main body 10 and the connecting portion 30 is provided with a limiting rib 305, and the other is provided with a first stop protrusion 303. After the connecting portion 30 is rotated relative to the main body 10 by a preset angle, the limiting rib 305 abuts against the first stop protrusion 303.

[0053] The user may set the limiting rib 305 or the first stop protrusion 303 in the main body 10 or the connecting portion 30 according to actual selection, and there is no specific limitation as long as the abutment and snap-fit ​​function can be achieved.

[0054] Specifically, the connecting portion 30 is provided with a first stop protrusion 303 and a second stop protrusion 304 , which are spaced apart in the rotation direction of the connecting portion 30 , and the limiting rib 305 can pass over the second stop protrusion 304 and abut against the first stop protrusion 303 .

[0055] The first stop protrusion 303 is larger than the second stop protrusion 304, so that the limiting rib 305 cannot go over the first stop protrusion 303. When the limiting rib 305 reaches the second stop protrusion 304, a greater force is required to enable the connecting part 30 to continue to rotate to go over the second stop protrusion 304. At this time, this structure is used to remind the user that the rotation will reach the limit position.

[0056] In one embodiment, the connecting portion 30 has a set of stop protrusions, including a first stop protrusion 303 and a second stop protrusion 304. When the connecting portion 30 rotates a full circle, it can pass the second stop protrusion 304 and abut against the first stop protrusion 303.

[0057] In one embodiment, the connection part 30 has two groups of stop protrusions, each group of stop protrusions includes a first stop protrusion 303 and a second stop protrusion 304. When the connection part 30 rotates half a circle, it can pass the second stop protrusion 304 and abut against the first stop protrusion 303. The two groups of stop protrusions are respectively set corresponding to the fully closed and fully opened states of the liquid outlet 1041, so that it can be more stably maintained in the fully closed or fully opened state.

[0058] It is understandable that there is no limit to the number of stop protrusions in the connecting portion 30, and the user can set it according to actual conditions, as long as it can prevent the liquid supply head 100 from continuing to rotate when the state is changed, thereby maintaining it in the corresponding state and avoiding misoperation.

[0059] Specifically, the liquid outlet 1041 and the light-transmitting area 103 are located on two opposite sides of the main body 10. Therefore, the liquid supply head 100 can perform phototherapy and facial cleansing non-simultaneously, and the phototherapy and facial cleansing are performed separately, thereby preventing the liquid at the liquid outlet 1041 from contaminating the light-transmitting area 103. Optionally, the main body 10 has a first side surface and a second side surface that are disposed opposite to each other, the first side surface is provided with a liquid outlet 1041, and the second side surface has a light-transmitting area 103, and the distance between the first side surface and the second side surface gradually decreases in the direction in which the connecting portion 30 points to the main body 10. Therefore, both the first side surface and the second side surface are disposed obliquely, and when any one of the first side surface and the second side surface is directed toward the facial skin, it can be ensured that the first side surface and the second side surface conform to the facial structure and adapt to the user's holding habits.

[0060] The main body 10 includes a shell and a cleaning brush head 104. The shell has a storage cavity 1011. The cleaning brush head 104 is provided with a liquid outlet 1041. The cleaning brush head 104 is snap-fitted with the shell. The housing 101 mentioned above includes a shell and a cleaning brush head 104. The cleaning brush head 104 is snap-fitted with the shell by providing a buckle, which facilitates the disassembly and assembly of the two, thereby facilitating the cleaning brush head 104. Of course, in other embodiments, the two can also be connected by screws or magnetically matched.

[0061] It should be noted that the cleaning brush head 104 is used to assist in cleaning. The cleaning brush head 104 can contact the skin during use to help clean the skin through physical friction. The cleaning brush head 104 is provided with a liquid outlet 1041. The position design of the liquid outlet 1041 ensures that the liquid can assist in cleaning while flowing out, thereby improving the cleaning effect.

[0062] Please refer to it again Figure 1 and Figure 2 Specifically, the liquid supply head 100 also includes a button unit 70, which includes a button body 701, an electrical connector 702 and a magnet 703. The button body 701 is provided with a mounting hole (not shown in the figure), which runs through the inner and outer sides of the button body. The electrical connector 702 is embedded in the mounting hole (not shown in the figure), and the magnet 703 is fixed to the button body 701. The button body 701 is arranged on the main body 10. When the button body 701 is pressed, the electrical connector 702 can contact the circuit board 50.

[0063] The key unit 70 is used for user operation, and various functions of the liquid supply head 100 are controlled by keys, such as starting or stopping liquid supply, light therapy and vibration, etc. When the key body is pressed, the electrical connector 702 can contact the circuit board 50, thereby triggering the corresponding function of the liquid supply head 100.

[0064] The electrical connector 702 may be a conductive column, a conductive protrusion, or a conductive sheet.

[0065] The magnet 703 can be magnetically attracted to other external power supply structures. For example, when the liquid supply head 100 needs to be charged, the key unit 70 is directly magnetically attracted to the end of the charger through the magnet 703, and the electrical connector 702 is electrically connected to the charger. The number of magnets 703 can be one or more, and the shape of the magnet 703 can be annular, circular, square, etc. The magnet 703 can hide the inside of the key body to avoid exposure and damage.

[0066] The second aspect of the utility model provides a liquid supply device, which includes a liquid container (not shown) and a liquid supply head 100, wherein the liquid container is connected to the other end of the liquid channel 3021. Specifically, the other end of the liquid channel 3021 can be configured as a larger concave cavity, and the end of the liquid container can be accommodated in the other end of the liquid channel 3021. In addition, the liquid channel 3021 can be connected to the liquid container by providing a thread on the cavity wall.

[0067] By implementing the above technical solution, the phototherapy and cleansing functions are integrated into one liquid supply head 100, so that cleaning and skin care can be performed at the same time, which improves the convenience and efficiency of use. At the same time, by rotating the liquid flow switch, the user can flexibly adjust the amount of liquid according to their needs. This can not only avoid waste, but also adjust the amount of liquid used according to different skin types and needs, which is convenient to implement.

[0068] The above are only some embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Anything that is directly or indirectly used in other related technical fields is also included in the patent protection scope of the present invention.
