Technical Field

[0001] This invention relates to the field of container technology, specifically to an application head and skin care product applicator. Background Technology

[0002] The applicator head is used to apply liquid media to the skin. When using skincare products with applicator heads, you usually hold the bottle and aim the applicator head at the area where you want to apply the product, allowing the media in the product to flow to the area. When using it, you need to control the entire product bottle. The user needs to hold and control the entire product bottle. Because the entire product bottle is quite heavy, it is relatively difficult to operate, so there is room for improvement. Summary of the Invention

[0003] The purpose of this invention is to address the deficiencies and shortcomings of the prior art by providing an application head and skin care product applicator that separates the application head from the bottle body.

The bidirectional pump can pump the material in the container sequentially through the liquid inlet, the first pipe body, the second pipe body, the first connecting end, and the second connecting end to the liquid storage tank. Furthermore, the bidirectional pump can pump the material in the liquid storage tank sequentially through the second connecting end, the first connecting end, the second pipe body, and the third pipe body from the first liquid outlet to the contact surface.

[0006] Optionally, the liquid storage tank includes a first end wall, a first peripheral wall, and a first piston. The first end wall is disposed at one end of the first peripheral wall. The first piston is movably assembled inside the liquid storage tank. The side wall of the first piston is sealed to the inner wall surface of the first peripheral wall to divide the liquid storage tank into an airtight first chamber and a second chamber. The first end wall, the first peripheral wall, and the first piston together enclose the first chamber. The second tube communicates with the first chamber. The first chamber is used to store the material transported by the pumping device. The second chamber is connected to atmospheric pressure.

[0008] Optionally, the contact surface is disposed on the first sidewall of the housing, and a first insertion portion is disposed on the inner wall surface of the first sidewall. The first liquid outlet passes through the first insertion portion, and the third tube is inserted into the first insertion portion. The housing also has a second sidewall, which is disposed opposite to the first sidewall. A second insertion portion is disposed on the inner wall surface of the second sidewall. The liquid inlet passes through the second insertion portion, and the first tube is inserted into the second insertion portion.

[0009] Optionally, the contact surface is provided with a liquid outlet, and the first liquid outlet penetrates the liquid outlet; the housing is movably fitted with a massage bead, the massage bead at least partially protruding from the contact surface, and the height of the liquid outlet protruding from the contact surface is less than the height of the massage bead protruding from the contact surface.

[0010] Optionally, a light-transmitting area is provided on the contact surface, and the applicator head further includes a first circuit board and an LED connected electrically. The first circuit board is disposed adjacent to the contact surface, and the LED is disposed on the side of the first circuit board facing the light-transmitting area.

[0034] Example 1:

[0035] This embodiment relates to an application head, such as... Figures 1-5 As shown, it includes: a housing 1, a liquid storage tank 2, a control circuit board 3, and a pumping device 4.

[0036] The housing 1 is provided with a liquid inlet 110 and a first liquid outlet 101. The housing 1 is used to detachably connect with the container 6. The housing 1 and the container 6 can be fixed by detachable means such as threaded connection, snap connection, plug-in or magnetic connection. The container 6 is used to store liquids such as essential oils, essence water, medicine or lotion. The inlet 110 is connected to the container 6. A contact surface 103 for skin contact is provided on the outer wall of the housing 1. A first outlet 101 is located on the contact surface 103, which is used to contact the skin to apply the material discharged through the first outlet 101 to the skin. A storage tank 2 is located inside the housing 1. A control circuit board 3 is located inside the housing 1. A pumping device 4 is located inside the housing 1 and electrically connected to the control circuit board 3. The storage tank 2 stores the material pumped from the container 6 by the pumping device 4, enabling the dispensing of material from the container 6. The pumping device 4 is connected to the inlet 110, the first outlet 101, and the storage tank 2. The design of the pumping device 4... The device enables electrically controlled dispensing or replenishment of liquid from the applicator head. Users can also adjust the flow rate of the pumping device 4 to the first outlet via the control circuit board 3, reducing waste. The detachable design of the applicator head and container 6 allows users to pump the skincare product into the storage tank before leaving home or on short trips. Afterward, the applicator head can be detached from the container, eliminating the need to carry both the applicator head and the entire bottle of skincare product. Furthermore, the detachable design of the applicator head and container 6 reduces hand strain by requiring only the lighter applicator head to be held during operation.

[0037] Specifically, the pumping device 4 has a first working state and a second working state. In the first working state, the control circuit board 3 controls the pumping device 4 to pump the material in the container 6 to the storage tank 2 through the liquid inlet 110, realizing electric replenishment of the storage tank 2 and simplifying the difficulty of manual operation. In the second working state, the control circuit board 3 controls the pumping device 4 to pump the material in the storage tank 2 to the contact surface 103 through the first liquid outlet 101, further simplifying the difficulty of manual operation. The material can be output for the user to apply without manual squeezing or pressing, and it is also easy to adjust the material flow rate of the application head, reducing material waste.

[0038] In this embodiment, to achieve portability of the application head, such as... Figure 3 , Figure 5As shown, the applicator head also includes a rechargeable battery 33, which is housed within the housing 1 and electrically connected to the control circuit board 3. The rechargeable battery 33 can be either a rechargeable or non-rechargeable battery; preferably, it is a rechargeable battery. To enable the applicator head to be reusable, it also includes a charger 34. The charger 34 is used to connect to an external power source, such as AC power, via an adapter to charge the battery. The charger 34 can be one of a wireless charging receiver coil, charging electrodes, a Lightning interface, a Micro-USB interface, a Type-C interface, or a circular DC interface.

[0039] In some embodiments not shown, to achieve electrically controlled liquid dispensing from the applicator head and electrically controlled liquid replenishment from the storage tank 2, the pumping device 4 includes a first pump body and a second pump body. Both the first and second pump bodies are electrically connected to the control circuit board 3. The input end of the first pump body is connected to the liquid inlet 110, and the output end of the first pump body is connected to the storage tank 2. The design of the first pump body enables electrically controlled liquid replenishment from the container 6 to the storage tank 2. The input end of the second pump body is connected to the storage tank 2, and the output end of the second pump body is connected to the first liquid outlet 101. The design of the second pump body enables the material in the storage tank 2 to be pumped through the first liquid outlet 101 to the contact surface 103 for user application.

[0040] Optionally, this allows for electrically controlled liquid dispensing from the applicator head and electrically controlled replenishment of the liquid reservoir 2. For example... Figure 3 , Figure 5As shown, the pumping device 4 includes a three-way pipe 41 and a bidirectional pump 42. The bidirectional pump 42 is electrically connected to the control circuit board 3. The bidirectional pump 42 has a first connecting end 420 and a second connecting end 421. The second connecting end 421 is connected to the liquid storage tank 2. Optionally, the second connecting end 421 can be connected to the liquid storage tank 2 by a fixed connection method such as welding or hot injection molding, or the second connecting end 421 can be connected to the liquid storage tank 2 by a detachable method such as a hose plug-in connection. The three-way pipe 41 includes a first pipe body 410, a second pipe body 411 and a third pipe body 412 that are connected to each other. The first pipe body 410 is connected to the liquid inlet 110. The second pipe body 411 is connected to the first connecting end 420. Optionally, the first connecting end 420 can be connected to the second pipe body 411 by a fixed connection method such as welding or hot injection molding, or the first connecting end 420 can be connected to the first pipe body 410 by a detachable method such as a hose plug-in connection. The third pipe body 412 is connected to the first liquid outlet 101. In the first operating state, the bidirectional pump 42 pumps the material in container 6 sequentially through inlet 110, first pipe 410, second pipe 411, first connecting end 420, and second connecting end 421 to the storage tank 2, completing electric replenishment. In the second operating state, the bidirectional pump 42 pumps the material in storage tank 2 sequentially through second connecting end 421, first connecting end 420, second pipe 411, and third pipe 412 through first outlet 101 to contact surface 103, achieving precise dispensing. There is no need to set up two separate electric pumps to control the replenishment of liquid in the storage tank 2 and the dispensing of liquid from the applicator head. By integrating a single bidirectional pump 42 with a three-way pipe 41 into the applicator head, the electric replenishment and dispensing functions can be reused. This reduces the need for an electric pump and its associated drive circuit, pipe interface and other components, thereby reducing material costs and simplifying the production and assembly process. At the same time, the design of only a single bidirectional pump 42 and a three-way pipe 41 can reduce the installation space of two electric pumps, effectively reducing the size and weight of the applicator head and effectively reducing hand fatigue during application.

[0041] In some embodiments not shown, to achieve normal liquid storage and drainage in the storage tank 2, the storage tank 2 includes a first end wall 20, a first peripheral wall 21, a second end wall, and a connecting pipe connected in sequence. The first end wall 20, the first peripheral wall 21, and the second end wall together form a first chamber for storing the material. One end of the connecting pipe extends into the first chamber along the direction from the first end wall 20 to the second end wall, and a second connecting pipe is connected to the other end of the connecting pipe, enabling the pumping device 4 to replenish or drain the first chamber. To balance the pressure difference in the first chamber, the first end wall 20 is provided with a pressure relief valve communicating with the first chamber.

[0042] In some embodiments, to achieve the normal liquid storage effect of the liquid storage tank 2, such as Figure 3 , Figure 5As shown, the storage tank 2 includes a first end wall 20, a first peripheral wall 21, and a first piston 22. The first end wall 20 is located at one end of the first peripheral wall 21. The first piston 22 is movably assembled inside the storage tank 2. The side wall of the first piston 22 is sealed to the inner wall of the first peripheral wall 21 to divide the storage tank 2 into an airtight first chamber and a second chamber. The first end wall 20, the first peripheral wall 21, and the first piston 22 together form the first chamber. The second pipe 411 communicates with the first chamber. The first chamber is used to store the material transported by the pumping device 4. Specifically, the second pipe 411 is connected to the first end wall 20 to communicate with the first chamber, and the second chamber is connected to atmospheric pressure.

[0043] It should be noted that when the bidirectional pump 42 continuously draws material from the storage tank 2 through the first end wall 20, the air pressure in the first chamber decreases. Since the first piston 22 is sealed to the inner wall of the first peripheral wall 21, the side of the first piston 22 away from the first end wall 20 is at atmospheric pressure. Because the atmospheric pressure is greater than the air pressure in the first chamber, the atmospheric pressure pushes the first piston 22 to move closer to the first end wall 20 to reduce the volume of the first chamber and balance the air pressure. The movement of the piston compensates for the volume of liquid that is drawn away, maintains the pressure stability of the liquid area inside the bottle, prevents the formation of a vacuum, and allows the liquid to be continuously and smoothly drawn out. When the bidirectional pump 42 is in operation... The material in container 6 is pumped into the first chamber through the first end wall 20 via the three-way pipe 41. The influx of material causes the pressure in the first chamber to rise, which pushes the first piston 22 to move away from the first end wall 20, thus expanding the volume of the first chamber. The movement of the first piston 22 compensates for the volume of the injected liquid, maintains the pressure inside the bottle, and prevents the internal pressure of the liquid storage tank 2 from being too high. The first end wall 20 of the liquid storage tank 2 only needs to be opened with a pipe connected to the second pipe 411 to realize the liquid inlet and outlet of the liquid storage tank 2. During this process, no new outside air enters the first chamber, reducing the risk of oxidation of the material in the liquid storage tank 2.

[0044] In some embodiments, such as Figure 1 , Figure 5 As shown, the housing 1 is also provided with a switch module 35, which is electrically connected to the control circuit board 3. The switch module 35 is used by the user to control the operation of the bidirectional pump 42. The switch module 35 can be a push switch, a toggle switch, or a touch switch.

[0045] In some embodiments not shown, the control circuit board 3 integrates a wireless communication module, so that electronic devices such as mobile phones and computers can communicate with the application head through the wireless communication module to control the application head through wireless communication. The wireless communication module can be a Bluetooth module, a 2.4G radio frequency module, or a Wi-Fi module, etc. The technology of controlling beauty devices and other electronic devices through wireless communication modules is relatively mature, and will not be described in detail in this embodiment.

[0046] In some embodiments not shown, to achieve automatic replenishment of the storage tank 2 and further reduce manual intervention, a liquid level sensor electrically connected to the control circuit board 3 is also installed inside the storage tank 2. The control circuit board 3 automatically controls the operation of the bidirectional pump 42 by detecting the signal from the liquid level sensor inside the storage tank 2. The liquid level sensor monitors the material level inside the storage tank 2 in real time. Specifically, when the liquid level is lower than the set lower limit, the control circuit board 3 controls the bidirectional pump 42 to switch to the first working state, so that the material in the container 6 is pumped sequentially through the inlet 110, the first pipe 410, the second pipe 411, the first connection end 420, and the second connection end 421 to the storage tank 2, completing the automatic replenishment. When the liquid level sensor detects that the liquid level in the storage tank 2 has risen to the set upper limit, the liquid level sensor sends a stop signal, and the control circuit board 3 shuts down the bidirectional pump 42, completing the replenishment cycle. In some illustrated embodiments, the applicator head is also equipped with an identification module electrically connected to the control circuit board 3. The identification module wakes up the liquid level sensor and monitors whether the applicator head and container 6 are assembled. When the identification module detects that the applicator head and container 6 are assembled, the identification module wakes up the liquid level sensor through the control circuit board 3. Only when the liquid level sensor signal detects that the material in the storage tank is insufficient will the control circuit board 3 control the bidirectional pump 42 to switch to the first working state to pump material into the storage tank 2. The identification module can be a pressure sensor, NFC receiving module, radio frequency receiving module, etc., located between the housing 1 and the container 6. On the other hand, the liquid level sensor can be woken up by the switch module 35.

[0047] Furthermore, to enable the first piston 22 to move within the first enclosure under atmospheric pressure, such as... Figure 2 As shown, the housing 1 is provided with a vent 114 that connects the inner cavity of the housing 1 with the outside, and the vent 114 is arranged opposite to the first piston 22.

[0048] In some embodiments, such as Figure 3As shown, the applicator head also includes a first valve body 43 and a second valve body 44. The first valve body 43 and the second valve body 44 can be selected as a one-way valve or an electrically controlled valve, etc. Optionally, the first valve body 43 is located inside the first tube 410 and is used to control the opening and closing of the first tube 410, or the first valve body 43 is located inside the liquid inlet 110 and is used to control the opening and closing of the liquid inlet 110. With the design of the first valve body 43, when the user holds the applicator head and the applicator head is separated from the container 6, the bidirectional pump 42 switches to the second working state to avoid the material from the first tube 410 being discharged to the outside through the liquid inlet 110 during the process of discharging the liquid storage tank 2, thus preventing the material from being discharged to the outside through the liquid inlet 110, contaminating the shell 1 and wasting the material. Optionally, the second valve body 44 is disposed inside the third tube 412 to control the opening and closing of the third tube 412, or the second valve body 44 is disposed inside the first liquid outlet 101 to control the opening and closing of the first liquid outlet 101; the design of the second valve body 44 is such that when the applicator head is assembled with the container 6 and the material in the liquid storage tank 2 is insufficient, the bidirectional pump 42 switches to the first working state, so that during the process of conveying the material in the container 6 to the liquid storage tank 2, the material is prevented from being discharged from the third tube 412 and the first liquid outlet 101 to the contact surface 103.

[0049] Preferably, such as Figure 3 , Figure 5 As shown, both the first valve body 43 and the second valve body 44 are one-way valves. When the bidirectional pump 42 switches to the first working state, the material enters the storage tank 2 through the one-way valve, the second pipe 411, the first connecting end 420, and the second connecting end 421. When the bidirectional pump 42 switches to the second working state, the material is discharged from the storage tank 2 through the second pipe 411, the second connecting end 421, the first connecting end 420, the third pipe 412, and another one-way valve from the first outlet 101 to the contact surface 103, realizing fully automatic bidirectional liquid transfer. The one-way valve design only requires one set of drive control circuit. By controlling the switching logic between the first and second working states of the bidirectional pump 42, the liquid replenishment and discharge functions of the storage tank 2 can be realized. There is no need to configure an independent reversing valve or a complex dual-pump system, thereby simplifying the liquid circuit structure and reducing the risk of cost and failure rate.

[0050] In some embodiments, such as Figure 3As shown, the contact surface 103 is disposed on the first side wall 10 of the housing 1. A first insertion part 102 is disposed on the inner wall surface of the first side wall 10. A first liquid outlet 101 passes through the first insertion part 102. A third tube 412 is inserted into the first insertion part 102. The connection between the three-way tube 41 and the first liquid outlet 101 is achieved through the insertion of the first insertion part 102 and the third tube 412. To reduce the risk of leakage, the first insertion part 102 and the third tube 412 are sealed together. The housing 1 also has a second side wall 11, the second... The side wall 11 is disposed opposite to the first side wall 10. A second insertion part 111 is provided on the inner wall surface of the second side wall 11. The liquid inlet 110 passes through the second insertion part 111. The first tube body 410 is inserted into the second insertion part 111. The connection between the three-way tube 41 and the liquid inlet 110 is realized through the insertion of the second insertion part 111 into the first tube body 410. In order to reduce the risk of leakage, the second insertion part 111 is sealed to the first tube body 410. The first insertion part 102 and the second insertion part 111 limit the three-way tube 41.

[0051] In some embodiments, such as Figure 1 , Figures 3-5 As shown, a liquid outlet 1031 is provided on the contact surface 103, and a first liquid outlet 101 penetrates the liquid outlet 1031. The liquid outlet 1031 protrudes from the contact surface 103, or the liquid outlet 1031 is a groove, or the liquid outlet 1031 contacts the contact surface 103. Optionally, the liquid outlet 1031 protrudes from the contact surface 103, and the outer surface of the liquid outlet 1031 is curved. The curved surface facilitates guiding the material discharged from the liquid storage tank 2 to the contact surface 103. The housing 1 is movably equipped with a massage bead 104, and the massage bead 104 at least partially protrudes from the contact surface 103. The height of the liquid outlet 1031 protruding from the contact surface 103 is less than the height of the massage bead 104 protruding from the contact surface 103, so as to avoid the skin blocking the first liquid outlet 101 and affecting the liquid discharge. The design of the massage beads 104 changes the sliding friction between the contact surface 103 and the skin to rolling friction, making the application of the product more comfortable. Simultaneously, the massage beads 104 guide the product from the contact surface 103 onto the skin, ensuring a more even application. In some embodiments, the contact surface 103 has a groove for accommodating the massage beads 104, which are movably fitted within the groove. A liquid guide groove is provided on the contact surface 103, connecting the groove to the first liquid outlet 101. The product flows from the first liquid outlet 101 through the liquid guide groove and the groove. When the massage beads 104 rotate, the product adhering to the groove is applied to the skin, ensuring even application.

[0052] In some embodiments, to increase the functionality of the application head, such as Figure 3 , Figure 5As shown, a light-transmitting area 105 is provided on the contact surface 103. The application head also includes a first circuit board 31 and LED beads 32 that are electrically connected. The first circuit board 31 is electrically connected to the main control board and is disposed adjacent to the contact surface 103. The LED beads 32 are disposed on the side of the first circuit board 31 facing the light-transmitting area 105. The light emitted by the LED beads 32 can pass through the light-transmitting area 105 and be emitted outward. The arrangement of the LED beads 32 enables the application head to perform phototherapy on the skin to promote the absorption of the material by the skin. Multiple LED beads 32 are arranged at intervals. The LED beads 32 are used to emit one or more combinations of blue light with wavelengths of 415-470nm, yellow light with wavelengths of 590-595nm, yellow light with wavelengths of 630-660nm, or near-infrared light with wavelengths of 800-1100nm. In this embodiment, the number and wavelength of the LED beads 32 are not limited, and the number and wavelength of the LED beads 32 can be customized according to requirements.

[0053] In some embodiments, to prevent the contact surface 103 of the applicator head from being exposed to the outside environment, which could lead to scratches or contamination of the contact surface 103, such as... Figure 4 As shown, the applicator also includes a protective cover 5, which is used to cover the contact surface 103. The protective cover 5 is detachably connected to the housing 1 by magnetic attraction or snap-fit.

[0054] Example 2:

[0055] This embodiment is an improvement on embodiment 1, and describes a skincare product application tool, such as... Figures 4-6 As shown, the device includes a container 6 and the aforementioned application head. The application head is detachably connected to the container 6. The application head and container 6 can be connected in a separable manner, such as by insertion, threaded connection, or snap-fit ​​connection. The container 6 is connected to the liquid inlet 110. The detachable connection between the application head and the container 6, and the connection between the container 6 and the liquid inlet 110 of the application head, facilitates the replenishment of the application head by the container 6 and makes it easy to detach the application head from the container 6. Simply holding the application head allows the application of the material to the skin.

[0056] In some embodiments, to achieve a detachable connection between the applicator head and the container 6 while ensuring that the liquid inlet 110 is connected to the container 6, such as... Figure 7 , Figure 8As shown, container 6 has a second outlet 621 communicating with inlet 110. A third insertion part 62 is provided on one side of container 6, through which the second outlet 621 passes. The shell 1 has a fourth insertion part 112 that inserts into the third insertion part 62. Inlet 110 passes through the fourth insertion part 112 and communicates with the second outlet 621. One of the third insertion part 62 and the fourth insertion part 112 is a boss, and the other is a groove that fits the boss. Through the plug-in connection between the third insertion part 62 and the fourth insertion part 112, the second outlet 621 and inlet 110 are automatically connected during insertion, thereby enabling rapid and stable replenishment of liquid from container 6 to the liquid storage tank 2 of the application head. After insertion, the fitting structure of the boss and groove provides positioning and guidance, ensuring accurate docking and preventing misalignment or loosening. When it is necessary to separate container 6 from the application head, simply pull them apart to automatically cut off the liquid replenishment path, reducing the risk of material leakage. This plug-in connection structure is simple and easy to operate, allowing users to quickly access the application head.

[0057] In some embodiments, such as Figure 8 As shown, a third one-way valve 622 is provided in the second liquid outlet 621. By providing the third one-way valve 622 in the second liquid outlet 621, after the applicator head is removed from the container 6, the third one-way valve 622 automatically seals the liquid outlet, reducing the risk of external dust or air entering the container 6 from the second liquid outlet 621 and contaminating or oxidizing the material.

[0058] In some embodiments, such as Figure 8 As shown, a sealing element 113 is provided between the third insertion part 62 and the fourth insertion part 112. The sealing element 113 is provided on the groove wall of the groove and is used to seal the gap between the third insertion part 62 and the fourth insertion part 112, thereby reducing the risk of leakage of the material during the process of passing through the third liquid outlet and the liquid inlet 110.

[0059] In some embodiments, such as Figure 7As shown, container 6 includes a cap 61 and a bottle body 63. The bottle body 63 is used to store skincare products or medicines. The cap 61 covers the opening of the bottle body 63, and a third insertion part 62 protrudes from the side of the cap 61 opposite to the opening. The cap 61 and the bottle body 63 are connected in a detachable manner by means of threaded connection or snap-fit ​​connection, so that the user can open the cap 61 to fill the bottle body 63 with the substance. Specifically, a second piston 64 is movably assembled inside the bottle body 63. The bottle body 63 includes a third end wall 631, a second peripheral wall 632, and a fourth end wall 633 connected in sequence. The outer wall of the second piston 64 is sealed to the inner wall of the second peripheral wall 632 to divide the bottle body into a third chamber and a fourth chamber. The third end wall 631, the second peripheral wall 632, and the second piston 64 together form a third chamber for storing material. An opening is formed on the third end wall 631 to connect to the third chamber. The second piston 64, the second peripheral wall 632, and the fourth end wall 633 together form a fourth chamber, which is connected to atmospheric pressure. Specifically, the fourth end wall 633 has a vent hole 114 through it, which is positioned opposite to the second piston 64. In this embodiment, the working principle of the container 6 is similar to that of the liquid storage tank 2, and will not be described again in this embodiment.

[0060] The above is only used to illustrate the technical solution of the present invention and not to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of the present invention, as long as they do not depart from the spirit and scope of the technical solution of the present invention, should be covered within the scope of the claims of the present invention.
