Description

Technical Field

[0001] This invention relates to the field of cosmetic container technology, specifically to a coating structure and a cosmetic container. Background Technology

[0002] Traditional solution application structures connect to a container and include a housing and a massage head. The massage head is rotatably attached to the housing, which in turn connects to the container. A liquid outlet is located at the front of the housing and communicates with the container. Under gravity or pressure, the solution inside the container flows to and from the outlet, and is then evenly applied to the skin by the massage head. However, when applying skincare products without using the massage head and when the cosmetic container is inverted, gravity causes the cosmetic to leak out of the outlet, leading to waste. Therefore, improvements are needed. Summary of the Invention

When the detection part rotates synchronously with the rolling part, the detection part can periodically pass through the light channel. Alternatively, there are multiple detection parts. The multiple detection parts are evenly spaced along the circumference of the rolling part. There is an obstacle gap between two adjacent detection parts to allow light to pass through. The multiple detection parts can pass through the light channel sequentially.

[0007] Preferably, the housing is provided with an annular guide groove coaxial with the rotating shaft, the guide groove surrounds the outer circumference of the rotating shaft, the photoelectric sensor is disposed on the groove wall of the guide groove, the detection part extends into the guide groove, and the detection part is rotatable along the guide groove.

[0008] Preferably, the application structure further includes a physiotherapy unit for stimulating the skin to provide physiotherapy. The physiotherapy unit is electrically connected to the main control board, and the main control board is signal-connected to the motion detection device. The detection signal includes a first detection signal and a second detection signal. When the motion detection device detects that the massage head assembly rotates relative to the housing, it outputs the first detection signal. The main control board can then control the electrically controlled valve to open the liquid outlet channel and start the physiotherapy unit based on the first detection signal. When the motion detection device detects that the massage head assembly is stationary relative to the housing, it outputs the second detection signal. The main control board can then control the electrically controlled valve to close the liquid outlet channel and stop the physiotherapy unit based on the second detection signal.

[0009] Preferably, the coating structure further includes a physiotherapy unit for stimulating the skin to provide physiotherapy.

[0010] Preferably, the rolling part is made of a light-transmitting material, and the physiotherapy unit includes a phototherapy lamp disposed on the rotating shaft, the phototherapy lamp facing the rolling part, and the light emitted by the phototherapy lamp can be emitted from the rolling part; and / or the rolling part is made of a heat-conducting material, and the physiotherapy unit includes a heating element or a cooling element that is heat-conductingly connected to the rolling part; and / or the physiotherapy unit includes a vibrating element disposed on the rotating shaft or the housing; and / or the rolling part includes a roller and a microneedle, the roller is sleeved outside the rotating shaft and the roller can rotate around the rotating shaft, the detection part is located on the roller, and the microneedle protrudes from the outer peripheral wall of the roller.

[0011] Preferably, the outer surface of the housing is provided with a liquid outlet communicating with the liquid outlet channel, the massage head assembly is spaced apart from the liquid outlet, and the massage head assembly is arranged opposite to the liquid outlet. The liquid outlet is used to export the skin care product flowing through the liquid outlet channel to the surface of the massage head assembly.

[0012] Preferably, the housing includes a first end wall, a first peripheral wall, and a second end wall connected in sequence, the second end wall being detachably connected to the liquid storage container; the housing is provided with a liquid outlet, the liquid outlet being disposed inside the housing, the liquid outlet including a liquid outlet section and a liquid inlet section, the liquid outlet section extending from the inside of the housing out of the outer surface of the first end wall, the liquid outlet being located at one end of the liquid outlet section away from the liquid inlet section; the liquid inlet section extending from the inside of the housing out of the second end wall, the liquid inlet being provided with a liquid inlet communicating with the liquid storage container at one end of the liquid inlet section away from the liquid outlet section, and the liquid outlet channel being disposed inside the liquid outlet for communicating with the liquid inlet and the liquid outlet.

[0013] A cosmetic container includes a liquid storage container and the above-described coating structure, wherein the coating structure is detachably connected to the liquid storage container.

[0014] After adopting the above technical solution, the beneficial effects of the present invention are as follows: the massage head assembly is rotatably mounted on the housing and is used to roll and apply the skin care product flowing out of the liquid outlet channel to the skin, so as to realize the basic function of the application structure to apply the skin care product to the skin, without the need for the user to apply the skin care product by hand, avoiding the skin care product residue on the hands, causing waste of skin care product and contamination of the hands;

[0015] The housing is equipped with an electrically controlled valve for opening or closing the liquid outlet channel.

By sensing the movement status of the massage head assembly in real time through the motion detection device, and cooperating with the main control board to control the electronically controlled valve to automatically open or close, the intelligent automatic liquid outlet function is achieved. The liquid outlet channel automatically opens when the coating action begins and closes when the coating action stops, eliminating the need for manual operation of the switch and improving portability. At the same time, it effectively solves the problem of uneven application and waste of skin care products caused by the massage head assembly remaining in the same position on the skin for a long time during the coating process, thus improving the economy of product use and reducing waste of skin care products.

[0039] Example 1:

[0040] This embodiment relates to a coating structure, such as Figure 1 - Figure 8 As shown, it includes a housing 1, a massage head assembly 2, an electronically controlled valve 3, a motion detection device 4, and a main control board 6.

[0041] The housing 1 is used to connect to the liquid storage container 7, which is used to store skin care products. Optionally, the housing 1 can be fixedly mounted on the liquid storage container 7. The housing 1 can be attached to the liquid storage container 7 by hot injection molding, adhesive bonding, or integral molding. Optionally, the housing 1 can be detachably assembled onto the liquid storage container 7. The housing 1 can be fixed to the liquid storage container 7 by means of threads or snaps.

[0042] like Figure 6 , Figure 8 As shown, the housing 1 is provided with a liquid outlet channel 101 connecting the outside to the liquid storage container 7. The massage head assembly 2 is rotatably mounted on the housing 1. The massage head assembly 2 is used to roll and apply the skin care product flowing out of the liquid outlet channel 101 onto the skin. The rotatable design of the massage head assembly 2 allows the skin care product to be evenly applied to the skin surface, and the rolling massage action of the massage head on the skin helps to promote the absorption of the skin care product.

[0043] like Figure 6 , Figure 8As shown, the electrically controlled valve 3 is disposed on the housing 1. The electrically controlled valve 3 is used to open or close the liquid outlet channel 101. Optionally, the electrically controlled valve 3 can be a shape memory alloy valve, a piezoelectric valve, a direct-acting solenoid valve, a pilot-operated solenoid valve, or a miniature normally closed solenoid valve. A motion detection device 4 is disposed on the housing 1 and / or the massage head assembly 2. The motion detection device 4 is used to detect the relative rotation between the massage head assembly 2 and the housing 1 to output a detection signal. Optionally, the motion detection device 4 can be a photoelectric sensor 40, an accelerometer, a piezoelectric sensor, a Hall sensor, or a rotary encoder, etc. Specifically, in some embodiments, such as... Figures 2-5 The motion detection device 4 is partially disposed on the housing 1 and partially disposed on the massage head assembly 2. In this embodiment, the motion detection module may be a photoelectric sensor 40, a Hall sensor, or a piezoelectric sensor. In some embodiments not shown, the motion detection device 4 may be an accelerometer disposed on the massage head assembly 2. In some embodiments not shown, the motion detection device 4 may be a rotary encoder disposed on the housing 1.

[0044] The main control board 6 is located on the housing 1 and is electrically connected to the electric control valve 3. The main control board 6 can control the electric control valve 3 to open or close the liquid outlet channel 101 according to the detection signal. The motion detection device 4 senses the motion status of the massage head assembly 2 in real time and, together with the main control board 6, controls the electric control valve 3 to open or close automatically, realizing the intelligent automatic liquid outlet function. The liquid outlet channel 101 is automatically opened when the application action begins and closed when the application action stops. There is no need to manually operate the switch, which improves portability. At the same time, it effectively solves the problem of uneven application and waste of skin care products caused by the massage head assembly 2 staying in the same position on the skin for a long time during the application process, thus improving the economy of product use and reducing waste of skin care products.

[0045] It should be noted that when the massage head assembly 2 rolls on the skin, and the motion detection device 4 detects relative rotation between the massage head assembly 2 and the housing 1 within a preset time, the main control board 6 controls the electric control valve 3 to open the liquid outlet channel 101 based on the detection signal transmitted by the motion detection device 4. When the massage head assembly 2 is stationary relative to the housing 1, and the motion detection device 4 does not detect relative rotation between the massage head assembly 2 and the housing 1 within a preset time, the main control board 6 controls the electric control valve 3 to close the liquid outlet channel based on the detection signal transmitted by the motion detection device 4.

[0046] In one embodiment (not shown), to enable the massage head assembly 2 to rotate relative to the housing 1, the housing 1 is provided with a shaft hole. The massage head assembly 2 includes a rolling part 21 and a rotating shaft part. The rolling part 21 is rotatably mounted on the shaft hole via the rotating shaft part. The rolling part 21 rotates synchronously with the rotating shaft part. The rolling part 21 and the rotating shaft part can be fixed by screws or hot injection molding, or the rolling part 21 and the rotating shaft part can be integrally formed and fixed.

[0047] In one embodiment, such as Figure 1 , Figure 2 , Figure 4 , Figure 6 , Figure 7 As shown, in order to enable the massage head assembly 2 to rotate relative to the housing 1, the housing 1 is provided with a rotating shaft 11. The rotating shaft 11 is fixed to the housing 1, and the rotating shaft 11 can be integrally formed into the housing 1 by hot injection molding, screws, or molding. The massage head assembly 2 includes a rolling part 21, which is sleeved on the rotating shaft 11 and can rotate around the rotating shaft 11.

[0048] In some embodiments, such as Figure 2 - Figure 7 As shown, to detect whether the massage head assembly 2 rotates, the motion detection device 4 includes a photoelectric sensor 40 and a detection unit 41. The detection unit 41 is mounted on the rolling part 21 and can move synchronously with the rolling part 21. The photoelectric sensor 40 is mounted on the housing 1 and includes a light emitter 401 and a light receiver 402. The light emitted by the emitter illuminates the motion path of the detection unit 41.

[0049] Specifically, in one embodiment, such as Figure 2 - Figure 7 As shown, the photoelectric sensor 40 can be a through-beam or slot-type photoelectric sensor 40. The detection unit 41 is rotatably disposed between the light emitter 401 and the light receiver 402 to block or conduct light transmission between the light emitter 401 and the light receiver 402. Optionally, the detection unit 41 can protrude along a third direction on the outer surface of the rolling part 21, and the third direction is parallel or perpendicular to the axis of the rotation shaft 11.

[0050] In some embodiments not shown, the photoelectric sensor 40 may be a reflective photoelectric sensor 40. The detection unit 41 includes a reflective area disposed on the outer surface of the rolling part 21. The light emitter 401 is used to emit light signals, and the light receiver 402 is used to receive light signals. The light emitter 401 and the light receiver 402 are located on the same side. The emitting area can reflect the light signal emitted by the light emitter 401 during the rotation following the rolling part 21. Specifically, when the massage head assembly 2 rotates relative to the housing 1, the reflective area periodically passes through the light beam path emitted by the light emitter 401. The light receiver 402 receives the light reflected from the emitting area and the non-radiating area, and outputs a corresponding pulse signal (detection signal) which is transmitted to the main control board 6. The main control board 6 controls the opening or closing of the electronic control valve 3 according to the received pulse signal.

[0051] Furthermore, such as Figure 2 - Figure 7As shown, the photoelectric sensor 40 can be a slot-type photoelectric sensor 40. The photoelectric sensor 40 is disposed adjacent to one end of the rotating shaft 11. The photoelectric sensor 40 is provided with a detection slot 403, which has an opening disposed opposite to each other along a first direction. The detection slot 403 also has two slot walls disposed opposite to each other along a second direction. A light emitter 401 and a light receiver 402 are respectively disposed on the two slot walls. The first direction is perpendicular to the second direction. A light channel is provided between the light emitter 401 and the light receiver 402. The detection unit 41 can enter or leave the light channel through the opening. The light emitter 401 and the light receiver 402 are respectively disposed on the two opposite slot walls of the detection slot 403, so that the light emitted by the light emitter 401 can be directly aligned with the light receiver 402, and the light path is stable. At the same time, the setting of the detection slot 403 can reduce the interference of external light on the light emitted by the light emitter 401, so that the photoelectric sensor 40 can more accurately detect whether the massage head assembly 2 is moving. In this embodiment, the first direction is perpendicular to the central axis of the rotating shaft 11.

[0052] In one embodiment, a detection unit 41 is provided. When the detection unit 41 rotates synchronously with the rolling part 21, the detection unit 41 can periodically pass through the light channel. For example, within a preset time (5 seconds), when the number of times the detection unit 41 passes through the light channel reaches or exceeds 3 times (the number of rotations of the detection unit 41 relative to the housing 1 is greater than or equal to 3 times), the light receiver 402 transmits a first detection signal to the main control board 6. The main control board 6 controls the electric control valve 3 to open the liquid outlet channel 101 according to the first detection signal. When the detection unit 41 passes through the light channel less than 3 times, the light receiver 402 transmits a second detection signal to the main control board 6. The main control board 6 controls the electric control valve 3 to close the liquid outlet channel 101 according to the second detection signal, thereby effectively reducing the risk of the electric control valve 3 accidentally opening the liquid outlet channel 101.

[0053] In one embodiment, such as Figure 4 , Figure 5 As shown, to reduce the risk of the solenoid valve 3 accidentally opening the liquid outlet channel 101, multiple detection units 41 are used. These multiple detection units 41 are evenly spaced along the circumference of the rolling part 21, and there is a clearance gap between adjacent detection units 41 to allow light to pass through. The multiple detection units 41 can pass through the light channel sequentially. Specifically, within a set time, when the number of times the detection unit 41 passes through the light channel reaches or exceeds a preset number, the light receiver 402 transmits a first detection signal to the main control board 6. The main control board 6 controls the solenoid valve to open the liquid outlet channel 101 according to the first detection signal. When the number of times the detection unit 41 passes through the light channel is less than the preset number, the light receiver 402 transmits a second detection signal to the main control board 6. The main control board 6 controls the solenoid valve 3 to close the liquid outlet channel 101 according to the second detection signal, thereby effectively reducing the risk of the solenoid valve 3 accidentally opening the liquid outlet channel 101. In this application, the preset time and preset number are not limited.

[0054] It should be noted that multiple detection units 41 and multiple clearance notches are arranged alternately in a circle on the rolling part 21. When the rolling part 21 rotates, it drives the detection units 41 to rotate synchronously. When the detection unit 41 rotates into the light channel between the light emitter 401 and the light receiver 402, the detection unit 41 blocks the light emitted by the light emitter 401, causing the light receiver 402 to be unable to sense light. Conversely, when the clearance notch rotates into the light channel, since there is no obstruction at the clearance notch, the light emitted by the light emitter 401 can completely penetrate and be normally received by the receiver. The light receiver 402 converts the light signal into an electrical pulse signal and transmits it to the main control board 6. The main control board 6 monitors the rotation speed of the rolling part 21 in real time by counting the number of times the pulse signal is turned on and off per unit time. The microprocessor built into the main control board 6 compares the actual number of measurements with a preset threshold. When the threshold is reached or exceeded, a first detection signal (high level) is triggered, which drives the solenoid valve coil to be energized to open the liquid outlet channel 101. When the threshold is lower, a second detection signal (low level) is generated, which controls the actuator of the electric control valve 3 to cut off the hydraulic circuit and close the channel.

[0055] In some embodiments, such as Figure 2 , Figure 3 As shown, the housing 1 is provided with an annular guide groove 102 coaxial with the rotating shaft 11. The guide groove 102 surrounds the outer circumference of the rotating shaft 11. The photoelectric sensor 40 is disposed on the groove wall of the guide groove 102. The detection part 41 extends into the guide groove 102 and can rotate along the guide groove 102. The photoelectric sensor 40 is disposed in the guide groove 102. The guide groove 102 is used to further block external light from entering the photoelectric sensor 40, thereby further reducing the interference of external light on the light of the photoelectric sensor 40.

[0056] In some embodiments, such as Figure 4 , Figure 6 , Figure 8As shown, to enhance the functionality of the coating structure, it also includes a physiotherapy unit 5. The physiotherapy unit 5 is used to stimulate the skin for therapeutic purposes. The physiotherapy unit 5 can be one or more combinations of a hot compress, a cold compress, a phototherapy component, a vibration component 53, a microcurrent electrode, or a radio frequency electrode. The physiotherapy unit 5 is electrically connected to the main control board 6. The detection signals include a first detection signal and a second detection signal. When the motion detection device 4 detects that the massage head assembly 2 rotates relative to the housing 1, it outputs the first detection signal. The main control board 6 can then control the electronically controlled valve 3 to open the liquid outlet channel 101 and control the physiotherapy unit 5 to start working based on the first detection signal. When the motion detection device 4 detects that the massage head assembly 2 is stationary relative to the housing 1, it outputs a second detection signal. The main control board 6 can control the electronic control valve 3 to close the liquid outlet channel 101 and control the physiotherapy unit 5 to stop working according to the second detection signal. By designing the physiotherapy unit 5 in the coating structure, when the massage head assembly 2 rotates relative to the housing 1, the motion detection device 4 transmits a first detection signal to the main control board 6. The main control board 6 synchronously controls the opening of the liquid outlet channel 101 and the operation of the physiotherapy unit 5 according to the received first detection signal, realizing the synchronization of liquid outlet and physiotherapy action, improving the convenience of use. At the same time, it ensures the synergistic effect of skin care product or drug application and physiotherapy function, thereby increasing the skin's absorption of skin care products or drugs, without the need to design a separate control switch to control the operation of the physiotherapy unit 5.

[0057] In some embodiments, such as Figure 4 , Figure 6 , Figure 8 As shown, the rolling part 21 is made of a light-transmitting material. The physiotherapy unit 5 includes a phototherapy lamp 51 mounted on the rotating shaft 11. The light emitted by the phototherapy lamp 51 can be emitted from the rolling part 21, allowing skincare products or medications flowing from the liquid outlet channel 101 to flow to the massage head assembly 2. During the application process, the massage head assembly 2 applies skincare products to the skin while simultaneously providing phototherapy. Specifically, the phototherapy lamp 51 can emit one or more wavelengths of light selected from 415nm blue light, 630nm red light, 850nm near-infrared light, 560nm green light, 610nm orange light, and 290nm-400nm ultraviolet light. The phototherapy lamp 51 can be one or more of a light-emitting diode, laser, fluorescent lamp, halogen lamp, electrodeless lamp, and xenon arc lamp, preferably a light-emitting diode and / or laser. In this embodiment, the user can change the light emitted by the lamp according to their needs.

[0058] Furthermore, such as Figure 2 , Figure 4 , Figure 6 , Figure 8As shown, the rotating shaft 11 includes a shaft body 110, within which a first mounting cavity is provided. The shaft body 110 has multiple light-transmitting holes 1101, which connect to the outside and the first mounting cavity. Each light-transmitting hole 1101 corresponds to a phototherapy lamp 51. To prevent liquid from entering the first mounting cavity through the light-transmitting holes 1101, a light-transmitting sleeve 111 for sealing the light-transmitting holes 1101 is also provided on the shaft body 110. The light-transmitting sleeve 111 is fitted over the shaft body 110 and fixedly connected to it. The light-transmitting sleeve 111 is fixed to the shaft body 110 by means of adhesive bonding or integral molding. In this embodiment, the massage head assembly 2 is fitted over the light-transmitting sleeve 111 and can rotate around it. In this embodiment, the physiotherapy unit 5 also includes a first circuit board 52 disposed within the first mounting cavity and electrically connected to the main control board 6. The phototherapy lamp 51 is integrated on the side of the first circuit board 52 adjacent to the cavity wall of the first mounting cavity.
