Description

Technical Field

[0001] This application relates to dispensers for cosmetic products, and more particularly to an applicator. Background Technology

[0002] Currently, applicators play a crucial role in modern skincare and makeup routines. Using a specialized applicator avoids direct contact with cosmetics or skincare products, reducing bacterial contamination and ensuring product hygiene and quality. At the same time, applicators help users apply products more evenly to the skin, enhancing the effectiveness of skincare and makeup.

[0003] Traditional applicators either require manually squeezing the container, which can easily result in too much or too little liquid being dispensed and is difficult to control; or they use a simple pouring method, which is not only inconvenient to operate but also easily leads to waste and contamination of skincare products. Utility Model Content

[0004] The technical problem this application aims to solve is: how to improve the convenience of the applicator.

[0005] To address the aforementioned technical problems, this application provides an applicator comprising: a housing; a flexible applicator head detachably connected to the end of the housing, the flexible applicator head including a plurality of channels; a container detachably connected to the tail of the housing, the container for containing cosmetic products; a heating device disposed within the flexible applicator head, the heating device for adjusting the temperature of the flexible applicator head; and a dispensing device comprising a micro-pump and a pressure sensor, the micro-pump being installed within the housing, the pressure sensor being installed at the connection between the flexible applicator head and the housing, the micro-pump being used to draw cosmetic products from the container when the pressure sensor is pressurized, and to transport the cosmetic products through the channels to the surface of the flexible applicator head.

[0006] In one embodiment, the applicator further includes a temperature adjustment knob mounted on the housing. The temperature adjustment knob is connected in series with the heating device and is used to adjust the voltage of the heating device to adjust the power of the heating device.

[0007] In one embodiment, the outer casing has several markings arranged around the temperature adjustment knob.

[0008] In one embodiment, the identifier is text or a graphic.

[0009] In one embodiment, the pressure sensor is a piezoelectric pressure sensor or a piezoresistive pressure sensor.

[0010] In one embodiment, the applicator also includes a cleaning switch mounted on the housing, which continuously activates the micro pump when the cleaning switch is turned on.

[0011] In one embodiment, the cleaning switch includes a first spring, a second spring, and a clutch rod. The length of the first spring is greater than the length of the second spring. The clutch rod is slidably connected to the outer casing. One end of the clutch rod abuts against the first spring, and the other end of the clutch rod protrudes from the mounting surface between the outer casing and the container. When the container is installed at the tail of the outer casing, the container pushes the clutch rod, causing the first spring to be separated from the second spring. When the container is removed from the tail of the outer casing, the first spring and the second spring adhere to each other and conduct under the action of elasticity, thereby closing the cleaning switch.

[0012] In one embodiment, the flexible applicator head is made of silicone and has several raised massage particles.

[0013] In one embodiment, the heating device is a PTC heating element.

[0014] In one embodiment, the applicator further includes a heat-conducting plate, on which a PTC heating element is disposed, and the heat-conducting plate is connected to the flexible applicator head.

[0015] Compared with the prior art, the applicator of this application has the following advantages:

[0016] Intelligent liquid dispensing is achieved through a dispensing device composed of a pressure sensor and a micro-pump. When the user presses the flexible applicator, the pressure sensor detects the pressure and triggers the micro-pump to draw an appropriate amount of cosmetic product from the container and transport it to the applicator surface through a tube. This method is not only convenient to operate but also allows for flexible control of the dispensing volume based on the user's pressing pressure, avoiding waste and contamination of cosmetic products and enhancing the user experience. The heating device is placed directly in the flexible applicator, enabling quick and precise temperature adjustment to ensure that the cosmetic product is applied at the appropriate temperature.

Detailed Implementation

[0026] The specific embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but are not intended to limit the scope of this application.

[0027] In the description of this application, it should be understood that the terms "first," "second," etc., in the specification, claims, and accompanying drawings are intended to distinguish similar objects and are not used to describe a specific order or sequence. It should be understood that such terms are interchangeable where appropriate so that embodiments of this application can be implemented using notation methods other than those shown in the illustrations or descriptions. Furthermore, "comprising," "having," and any variations thereof are intended to cover non-exclusive inclusion. For example, a product or device comprising a series of components or units is not limited to those explicitly listed components or units, but may also include other components or units not explicitly listed but inherent to these products or devices. The beauty products in this application may include skincare products and cosmetics; whether skincare products or cosmetics are used does not affect the implementation of the solution in this application. To facilitate observation of the structure of the applicator of this application, the wiring connections are hidden in the drawings; the wiring connections can refer to conventional connection methods and waterproof structures.

[0028] In modern skincare and makeup routines, applicators play a crucial role. They enhance skincare effectiveness by promoting product absorption, allowing nutrients to penetrate deep into the skin, and ensuring even application so that all areas of the skin are nourished. In terms of convenience, these devices allow for precise dosage control, are easy to operate, and are suitable for individuals with specific needs. From a hygiene perspective, they reduce bacterial contamination and prevent cross-infection. Furthermore, some devices offer massage and relaxation functions, improve skin texture, and provide additional skincare benefits.

[0029] However, the inventors discovered that traditional applicators either require manually squeezing the container, which can easily result in too much or too little liquid being dispensed, making it difficult to control; or they use a simple pouring method, which is not only inconvenient to operate but also easily leads to waste and contamination of skincare products.

[0030] Based on this, such as Figure 1-3 The image shown is a preferred embodiment of an applicator 1 according to this application. The applicator 1 may include: a housing 11, a flexible applicator head 12, a container 13, a heating device 14, and a suction device 15.

[0031] The flexible applicator head 12 is detachably connected to the end of the housing 11, and includes several channels 121. A container 13 is detachably connected to the tail of the housing 11, and is used to hold skincare products. A heating device 14 is placed inside the flexible applicator head 12, and is used to adjust the temperature of the flexible applicator head 12. The dispensing device 15 includes a micro-pump 151 and a pressure sensor 152. The micro-pump 151 is installed in the housing 11, and the pressure sensor 152 is installed at the connection between the flexible applicator head 12 and the housing 11. The micro-pump 151 is used to draw skincare products from the container 13 when the pressure sensor 152 is pressurized, and to transport the skincare products through the channels 121 to the surface of the flexible applicator head 12.

[0032] Traditional applicators 1, which manually squeeze the container 13, make it difficult to control the amount of liquid dispensed. However, the dispensing device 15 in this solution works in conjunction with a micro-pump 151 and a pressure sensor 152. The micro-pump 151 only draws skincare product from the container 13 when the pressure sensor 152 is pressurized. This means that users can control the amount of liquid dispensed relatively precisely based on the pressure applied and the duration of application, avoiding situations where too much or too little liquid is dispensed.

[0033] Compared to the inconvenient traditional pouring method, this applicator dispenses liquid with just one press, eliminating the need for complicated pouring actions. It is especially convenient for skincare products with viscous textures or irregular bottle shapes, greatly enhancing the user experience.

[0034] Traditional pouring methods are prone to waste and contamination. The micro pump 151 of this applicator 1 dispenses liquid on demand, which can effectively reduce waste caused by excessive liquid dispensing. At the same time, the container 13 is detachably connected to the outer shell 11 and delivers skin care products to the surface of the flexible applicator head 12 through the pipe 121, avoiding excessive contact between the skin care products and the outside world and reducing the risk of contamination.

[0035] Meanwhile, the heating device 14 can adjust the temperature of the flexible applicator head 12. When applying skin care products, the warm applicator head can promote blood circulation in the skin, making the user feel more comfortable. It may also help the skin care products be better absorbed and improve the skin care effect.

[0036] The flexible applicator head 12 is detachably connected to the end of the outer shell 11, and the container 13 is detachably connected to the tail of the outer shell 11. This allows users to clean the applicator 1 regularly and replace it when the flexible applicator head 12 or the container 13 is damaged or used up, thus extending the service life of the applicator 1 and ensuring hygiene during use.

[0037] It is understood that the conduit 121 in the flexible applicator 12 can be a conduit 121 inserted later, a channel integrally formed with the flexible applicator 12, or a channel naturally formed by the material used in the flexible applicator 12. The specific type of conduit 121 used depends on the actual production needs of the product. When its structure can achieve the function of the conduit 121 in this application, the structure should be identified as the conduit 121 defined in this application.

[0038] During product development, the inventors further discovered that relying solely on the temperature heating device 14 was insufficient to meet more advanced skincare needs. In the skincare field, for example, the optimal application temperature for moisturizing creams is generally 30-32℃. This temperature allows the oils and moisturizing factors in the cream to better penetrate the skin, exerting their hydrating and moisturizing effects. For serums containing retinol, the optimal application temperature is 25-28℃. At this temperature, retinol is more stable and can be effectively absorbed by the skin to achieve anti-wrinkle and skin-improving effects. In cosmetics, the ideal application temperature for foundation is 26-29℃. This temperature allows the foundation to adhere more evenly to the skin, resulting in a natural and flawless finish. Lip glosses, when applied at around 30℃, have a smoother texture and are less prone to clumping or uneven application.

[0039] Since the optimal operating temperature ranges for different skincare and cosmetic products vary so much, a fixed-temperature applicator 1 cannot meet all needs. Therefore, in one embodiment of this application, the applicator 1 further includes a temperature adjustment knob 16, which is mounted on the housing 11 and connected in series with the heating device 14. The temperature adjustment knob 16 is used to adjust the voltage of the heating device 14 to adjust the power of the heating device 14.

[0040] By adjusting the temperature of the applicator head, it is possible to better adapt to the characteristics of different skincare products and improve their efficacy.

[0041] It is understandable that the temperature adjustment knob 16 can be a sliding rheostat. By rotating the knob, the resistance value of the rheostat is changed, thereby changing the current in the circuit. The change in current affects the power of the heating or cooling element, thus achieving temperature regulation.

[0042] Temperature adjustment knob 16 is widely used and has a reliable structure. The mechanical knob adjusts the voltage through precision gear transmission or variable resistance element. It is durable and has strong anti-interference ability. Even under frequent use, it can maintain stable adjustment performance and is not prone to failure.

[0043] To facilitate user temperature adjustment, such as Figure 7 As shown, the outer casing 11 may have several markings 17 arranged around the temperature adjustment knob 16.

[0044] By designing the label 17, compared to the temperature display scheme, it is possible to more intuitively determine the temperature that should be adjusted for skincare.

[0045] Furthermore, the identifier 17 can be text or a graphic.

[0046] For example, text-based designs could include foundation, eye cream, face mask, concealer, etc. Example designs can be found in the attached image.

[0047] It is understood that there are many types and styles of skin care and cosmetic products. The categories and usage temperatures exemplified in this application are merely illustrative. The applicator 1 in this application can be used in the application or application process of any skin care or cosmetic product. Even cosmetics or skin care products of the same category may correspond to different optimal usage temperatures due to differences in their main ingredients. Therefore, the specific usage temperature and the arrangement of the markings 17 can be determined according to the market situation or other needs at the time of product launch. This application does not make specific requirements in this regard, and the solutions obtained by making changes based on this also fall within the protection scope of this application.

[0048] In any embodiment of this application, the pressure sensor 152 may be a piezoelectric pressure sensor or a piezoresistive pressure sensor.

[0049] To facilitate cleaning of the applicator 1, in this application, the applicator 1 may also include a cleaning switch 18, which is mounted on the housing 11. When the cleaning switch 18 is turned on, the micro pump 151 is continuously energized.

[0050] When the cleaning switch 18 is turned on, the micro pump 151 is continuously turned on, so it can continuously draw clean water and pump it to the applicator head. After a period of time, this can clean the applicator head.

[0051] Promptly remove any residual skincare and cosmetic products from the applicator head to prevent bacterial growth and cross-contamination, ensuring cleanliness and hygiene every time the applicator 1 is used. Cleaning also extends the lifespan of the applicator 1; timely cleaning prevents residual substances from corroding or clogging the internal structure and pipes 121, reducing equipment malfunctions, lowering maintenance costs, and enabling the applicator 1 to operate stably for a long period.

[0052] In this application, the cleaning switch 18 can be a common switch, such as a rocker switch or a self-locking push button switch.

[0053] In addition, such as Figure 4-6 As shown, this application also provides a more convenient cleaning switch 18. The cleaning switch 18 may include a first spring 181, a second spring 182 and a clutch lever 183. The length of the first spring 181 is greater than the length of the second spring 182. The clutch lever 183 is slidably connected to the housing 11. One end of the clutch lever 183 abuts against the first spring 181, and the other end of the clutch lever 183 protrudes from the mounting surface of the housing 11 and the container 13.

[0054] When container 13 is installed at the tail of housing 11, container 13 pushes clutch lever 183, causing the first spring 181 to be separated from the second spring 182 by force. When container 13 is removed from the tail of housing 11, the first spring 181 and the second spring 182 stick together and conduct under the action of elastic force to close the cleaning switch 18.

[0055] With the above solution, during normal use, i.e., when the container 13 is installed on the outer casing 11, the two springs are disengaged by the force of the clutch lever 183, thus disengaging the cleaning switch 18. The micro pump 151 will not remain continuously activated, and will still be controlled by the pressure sensor 152 to gradually pump out skincare or cosmetic products. However, once the container 13 is removed from the outer casing 11, due to the elasticity of the springs, the first spring 181 can push out the clutch lever 183, and simultaneously, the first spring 181 and the second spring 182 come into contact, achieving the effect of closing the cleaning switch 18. With this solution, there is no need to manually open the cleaning switch 18; the cleaning switch 18 can be triggered synchronously with the removal of the container 13, improving user experience and operational convenience.

[0056] Understandably, in addition to any of the above solutions, a main power switch can also be provided. This main power switch controls the power supply to the applicator 1, allowing for power-off in case the cleaning function is accidentally triggered. For example, when drying after cleaning, there is no need to turn on the cleaning switch 18; the power can be cut off via the main power switch.

[0057] Furthermore, a stop 1831 can be provided on the clutch lever 183 in this application, and the elastic element 184 in the housing 11 can be compressed between the housing 11 and the stop 1831. When the container 13 is removed, the elastic force of the elastic element 184 can assist the elastic force of the first spring 181, so that the clutch lever 183 can be ejected more stably.

[0058] By designing the stop 1831 and the elastic element 184, sufficient elastic force can still be provided to make the clutch lever 183 pop out when the elasticity of the first spring 181 decays, thereby improving the stability of the device.

[0059] In one embodiment, the flexible applicator 12 is made of silicone and has several raised massage particles on it.

[0060] The flexible applicator head 12 is made of silicone, which will not cause stinging or discomfort when in contact with the skin and is suitable for all skin types, including sensitive skin. Silicone also has good chemical stability and corrosion resistance, extending the lifespan of the applicator head. Furthermore, silicone is easy to clean, with a smooth surface that does not easily retain dirt and bacteria. Combined with the cleaning switch 18, it can quickly and thoroughly clean the area, maintaining good hygiene.

[0061] In one embodiment, the heating device 14 is a PTC heating element.

[0062] PTC heating elements feature automatic temperature control. When the temperature reaches a certain value, their resistance increases sharply, limiting the current and preventing overheating. This avoids scalding the user or damaging the applicator and skincare products, whereas traditional heating wires can cause safety hazards due to uncontrolled temperature. Furthermore, PTC heating elements automatically reduce power after reaching the set temperature, minimizing unnecessary energy consumption and making them more energy-efficient than devices that continuously heat at high power.

[0063] In one embodiment, the applicator 1 further includes a heat-conducting plate, on which a PTC heating element is disposed, and the heat-conducting plate is connected to the flexible applicator head 12.

[0064] Through the conduction of the heat-conducting plate, heat can be more evenly distributed on the flexible applicator head 12, avoiding local overheating or undercooling. This ensures that the temperature of the skin remains consistent during use, improving the user experience and allowing skincare or cosmetic products to be heated evenly on the skin for better efficacy.

[0065] The heat-conducting plate helps to control the temperature of the flexible applicator head 12 more precisely. Because the heat-conducting plate has a certain heat capacity, it can buffer and regulate temperature fluctuations in the PTC heating element, resulting in more stable and accurate temperature control. This is beneficial for meeting the precise temperature requirements of different skincare and cosmetic products.

[0066] In another embodiment, a semiconductor cooling chip can be used as the heating device 14, making the heating device 14 a more comprehensive temperature control device, capable of both heating and cooling, thus broadening the applicator 1's applicability. For example, the low-temperature applicator 1 can be used for cold compresses, constricting blood vessels, reducing skin inflammation and redness, and alleviating skin allergies or acne. Appropriate warm stimulation helps promote blood circulation, accelerate skin cell metabolism, assist in skin self-repair, and promote healthier skin.

[0067] Compared with the prior art, the advantages of the applicator 1 in this application are as follows:

[0068] The suction device 15, composed of a pressure sensor 152 and a micro-pump 151, enables intelligent liquid dispensing. When the user presses the flexible applicator head 12, the pressure sensor 152 detects the pressure and triggers the micro-pump 151 to extract an appropriate amount of skincare product from the container 13 and transport it to the surface of the applicator head through the tube 121. This method is not only convenient to operate but also allows for flexible control of the liquid dispensing volume based on the user's pressing pressure, avoiding waste and contamination of the skincare product and improving the user experience. The heating device 14 is placed directly in the flexible applicator head 12, enabling rapid and precise adjustment of the applicator head's temperature to ensure that the skincare product is applied at a suitable temperature.

[0069] The above are merely preferred embodiments of this application. It should be noted that, for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this application, and these improvements and substitutions should also be considered within the scope of protection of this application.
