Technical Field

[0003] This application relates to the field of beauty product technology, and in particular to a hydration device. Background Technology

[0004] With the rapid development of technology and the improvement of living standards, people are paying more and more attention to their personal appearance, and beauty devices are gradually appearing in their lives. Among them, hydration devices, as a convenient and portable skincare product, have the functions of hydrating and moisturizing, maintaining the skin's water-oil balance, reducing wrinkles, and serving as a makeup base, and are therefore favored by many beauty-conscious women.

[0005] In related technologies, facial hydration devices include components such as a casing, an air pump, a water reservoir, and control components. The water reservoir provides the hydrating liquid, and the air pump provides air pressure to atomize the hydrating liquid and spray it onto the face to achieve a hydrating effect. Because facial hydration devices need to be portable, they need to be developed towards miniaturization and portability. However, such devices often use only one air pump. To achieve different air pressure levels, the air pump needs to have a relatively high power output, resulting in a large volume occupied by the single air pump. This makes it difficult to arrange the layout of the other components and meet the requirements for miniaturization and compactness. Summary of the Invention

[0006] The main purpose of this application is to propose a water replenishment device that addresses the issue that the air pump in existing water replenishment devices affects the layout of various components, making it difficult to achieve miniaturization and compactness.

[0060] This application proposes a water replenishment device 1.

[0061] Referring to Figures 1, 2, 4, and 5, in one embodiment of this application, the water replenishment device 1 includes a housing assembly 10, a water storage bullet 30, and at least two air pumps 20. The housing assembly 10 includes a housing 11 and a nozzle 12. A first mounting cavity 1131 is formed inside the housing 11. The nozzle 12 is installed in the housing 11 and communicates with the first mounting cavity 1131. The nozzle 12 includes a body and an air connector 121 and a water connector 122 located at one end of the body facing the first mounting cavity 1131 and communicating with the body. The water storage bullet 30 is installed in the housing 11 and communicates with the water connector 122. At least two air pumps 20 are installed in the first mounting cavity 1131 and communicate with the air connector 121. The airflow generated by the air pumps 20 mixes with the liquid provided by the water storage bullet 30 and is atomized by the nozzles 12 before being sprayed out.

[0062] In this embodiment, the water replenishment device 1 is designed as a long strip shape for easy hand operation, and the edges and corners of the long strip water replenishment device 1 are rounded to improve the grip. The outer shell 11 is made of high-strength engineering plastic, which has good mechanical strength and chemical corrosion resistance, and the surface is smooth and easy to clean.

[0063] The water flow from the water reservoir 30 and the airflow from the air pump 20 mix inside the nozzle 12. The water flow is fully dispersed under the action of the high-speed airflow, thus achieving a good atomization effect. The atomized spray is then ejected from the water outlet of the nozzle 12 to achieve the purpose of facial hydration. The nozzle 12 is located at the top of the device, allowing the user to easily and naturally aim it at the face or other areas requiring care. The water reservoir 30 is designed with portability and ease of use in mind, using a detachable, embedded connection to the outer casing 11 for convenient replacement or replenishment of moisture at any time.

[0064] The water storage bomb and the water connector 122 can be connected by plugging or by air pipe; the same applies to the air pump and the air connector 121.

[0065] Since this application incorporates at least two air pumps 20, the required air pressure for a single air pump 20 is lower. Consequently, the volume occupied by a single air pump 20 in the first mounting cavity 1131 is smaller, facilitating the rational arrangement of the air pumps 20 according to the shape of the internal components and the available space of the water replenishment device 1, thus meeting the requirements for miniaturization and compactness. This design not only optimizes the internal structure and reduces assembly space but also better adapts to the personalized needs of different users. Furthermore, the independent operating characteristics of each air pump 20 allow for series or parallel connection between them. Even if one air pump 20 fails, the other air pump 20 can continue to operate, ensuring the stability and reliability of the equipment.

[0066] As shown in Figures 2 and 4, in one embodiment of this application, there are two air pumps 20, which are spaced apart in a direction perpendicular to the axial direction of the air pumps 20 and located at the end of the housing 11 away from the nozzle 12 and the water storage bullet 30.

[0067] In this embodiment, the two air pumps 20 are placed parallel to each other on the same horizontal line, maintaining an appropriate distance. This layout ensures that each air pump 20 has sufficient installation space without interfering with each other, while avoiding heat conduction problems or resonance phenomena that may be caused by close proximity. The spacing also helps with heat dissipation and extends the service life of the air pumps 20.

[0068] The two air pumps 20 can be configured with different specifications or the same specifications. For example, as shown in Figure 4 of this embodiment, the two air pumps 20 are selected with the same specifications and size, and the two air pumps 20 are set at the bottom of the water replenishment device 1, that is, at the end of the outer shell 11 away from the nozzle 12 and the water storage bullet 30. Since the air pumps 20 are relatively heavy, this design can improve the grip of the water replenishment device 1 during use and improve the stability when placed. In addition, since the two air pumps 20 have the same or similar weight, when the two air pumps 20 are spaced apart in a direction perpendicular to the axial direction of the air pumps 20, the two air pumps 20 can be set in a left-right symmetrical structure within the first mounting cavity 1131 to further improve the stability of the structure and the grip. At the same time, this symmetrical structural design can also further improve the space utilization inside the outer shell 11 and facilitate the layout of the structure.

[0069] Additionally, when the water replenishment device 1 is operating and the required air pressure for atomization is low, both air pumps 20 can be configured to output lower power, or only one air pump 20 can be controlled to operate. For example, one air pump 20 can be used as the main drive source to generate the basic airflow; the other can act as an auxiliary pressurization unit to further pressurize the airflow, ultimately forming a stable high-pressure airflow to drive the liquid for atomization. This method not only provides a higher pressure range but also allows for flexible adjustment of the output power according to actual needs. For example, in low-power mode, only the main air pump 20 operates; while in high-power mode, both air pumps 20 work together to achieve a stronger spray effect. Of course, both air pumps 20 can also be set to output power simultaneously in both low-power and high-power modes.

[0070] Each air pump 20 is mounted on a base with elastic support, which can absorb and disperse vibration energy to a certain extent, reduce the vibration intensity transmitted to other components, and reduce noise generation.

[0071] In one embodiment of this application, a layer of sound-insulating material is wrapped around the air pump 20, which effectively reduces the noise generated during operation and improves the user experience.

[0072] As shown in Figures 2 to 4, in one embodiment of this application, the housing assembly 10 further includes a plurality of air pipes 50, the water storage bomb 30 is connected to the water connector 122 through an air pipe 50, and the two air pumps 20 are connected to the air connector 121 through air pipes 50.

[0073] In this embodiment, by setting up an air pipe 50 and connecting the water reservoir 30 to the water connector 122, and the air pump 20 to the air connector 121 via the air pipe 50, the convenience of the layout of each component and the convenience of the connection between the air and water circuits are improved. The air pipe 50 uses a quick-plug interface with the air pump 20, water reservoir 30, and nozzle 12, which not only simplifies the assembly process but also allows users to easily replace damaged parts. At the same time, waterproof sealing rings are added to all interfaces, improving the product's waterproof sealing performance.

[0074] Referring to Figures 2 and 4, in one embodiment of this application, the air outlet 3411 of one air pump 20 is connected to the air inlet 3311 of another air pump 20 through an air pipe 50, and the air outlet 3411 of the other air pump 20 is connected to the air connector 121 through another air pipe 50.

[0075] In this embodiment, the two air pumps 20 are connected in series. Specifically, the first air pump 20 initially compresses the air, and then the compressed gas is transmitted to the second air pump 20 for secondary pressurization through the air pipe 50. Finally, the high-pressure airflow after double compression flows out from the outlet 3411 of the second air pump 20 and directly reaches the nozzle 12 through the air pipe 50, forming a powerful atomization force. This design allows the first air pump 20 to run independently during the startup phase, and the second air pump 20 to be turned on after the pressure stabilizes, avoiding the impact of a sudden large current on the circuit system. Furthermore, this series connection of the two air pumps 20 not only facilitates multi-level adjustment functions but also reduces the workload of a single air pump 20, extending the service life of the equipment.

[0076] As shown in Figure 3, in one embodiment of this application, the water replenishment device 1 further includes a three-way pipe 23, the air outlets 3411 of the two air pumps 20 are respectively connected to two channels of the three-way pipe 23, and the other channel of the three-way pipe 23 is connected to the air connector 121 through the air pipe 50.

[0077] In this embodiment, the two air pumps 20 are connected in parallel via a three-way pipe 23. The three-way pipe 23 can be Y-shaped or T-shaped. The inner surface of the three-way pipe 23 is specially treated to be smooth and burr-free, ensuring smooth airflow and facilitating daily cleaning and maintenance. To adapt to different operating environments, the three-way pipe 23 can be made of high-pressure resistant and corrosion-resistant materials, such as high-strength plastics or metal alloys, to ensure long-term stable operation. The airflow generated by the two air pumps 20 converges at the three-way pipe 23 after entering, forming a higher and more uniform airflow.

[0078] This design, which utilizes a three-way pipe 23 to connect two air pumps 20 in parallel, solves the problem of traditional hydration devices 1 struggling to coordinate the synchronous operation of multiple air pumps 20, achieving effective integration and optimized distribution of airflow. Users can easily switch between different speeds according to their actual needs, obtaining a more stable and efficient skincare experience.

[0079] As shown in Figures 4 and 5, in one embodiment of this application, the housing 11 forms two first mounting cavities 1131, and each air pump 20 is embedded in one of the first mounting cavities 1131.

[0080] In this embodiment, to improve the ease of installation of the two air pumps 20, two first mounting cavities 1131 are provided inside the housing 11 of the water replenishment device 1. Each of these two first mounting cavities 1131 provides a dedicated mounting position for one air pump 20, thus avoiding potential interference between the two air pumps 20. When the two air pumps 20 have different models or sizes, different shapes and sizes of first mounting cavities 1131 can be provided according to different models of air pumps 20 to achieve compatibility between the air pumps 20 and the first mounting cavities 1131. In addition, the two separate first mounting cavities 1131 help to disperse heat and prevent excessively high local temperatures from affecting equipment performance or safety.

[0081] As shown in Figures 1 and 5, in one embodiment of this application, the outer shell 11 includes a front shell plate 1111 and a rear shell plate 1121, which are detachably connected. The front shell plate 1111 and the rear shell plate 1121 enclose each other to form two first mounting cavities 1131.

[0082] In this embodiment, the front shell 1111 and the rear shell 1121 are detachably connected by means of snap-fit, threaded connection or plug-in. By setting the outer shell 11 so that the front shell 1111 and the rear shell 1121 are detachably connected, when it is necessary to repair or replace the internal components of the water replenishment device 1, the user can easily open the outer shell 11 with simple operation without the need for professional tools.

[0083] Furthermore, the front shell 1111 and the rear shell 1121 fit together tightly, forming two independent first mounting cavities 1131, with each air pump 20 embedded in one of the first mounting cavities 1131. This layout not only provides dedicated installation space for the air pumps 20, avoiding mutual interference, but also improves the ease of installation for the two air pumps 20. During installation, the air pump 20 is simply inserted into either the front shell 1111 or the rear shell 1121, and then the front shell 1111 and the rear shell 1121 are fastened together. To improve waterproofing, the joints between the front shell 1111 and the rear shell 1121 are sealed, including critical areas such as the air pipe 50 connection port and the power cord inlet, to prevent liquid infiltration and damage to internal electronic components.

[0084] In addition, control panels can be integrated on the front shell 1111 and the rear shell 1121, with various operation buttons and indicator lights arranged in a centralized manner, so that users can intuitively grasp the status of the equipment and make adjustments.

[0085] Referring to Figures 4 and 5, in one embodiment of this application, one end of the air pump 20 connected to the air passage connector 121 is the first end 21, and the other end of the air pump 20 is the second end 22. The cross-sectional dimension of the first end 21 is larger than that of the second end 22. The cavity wall of the first mounting cavity 1131 is provided with a limiting step 116. The second end 22 is inserted into the first mounting cavity 1131, and the first end 21 abuts against the limiting step 116.

[0086] In this embodiment, one end (first end 21) of the air pump 20 is designed with a larger cross-sectional size, while the other end (second end 22) is relatively smaller. This stepped design can provide clear directional guidance during installation and prevent reverse installation or misoperation.

[0087] The first mounting cavity 1131 has a dedicated limiting step 116 on its cavity wall, or the first mounting cavity 1131 can also be set in a stepped shape to adapt the shape of the first mounting cavity 1131 to the air pump 20. When the air pump 20 is inserted into the first mounting cavity 1131, the first end 21 abuts against the limiting step 116, and the second end 22 abuts against the bottom wall of the first mounting cavity 1131, and together they provide physical support for the air pump 20. The presence of the limiting step 116 also allows the air pump 20 to maintain a stable position when subjected to external impact or vibration, reducing the risk of loosening or displacement.

[0088] As shown in Figure 5, in one embodiment of this application, the cavity wall of the first mounting cavity 1131 is provided with a plurality of limiting ribs 117, and the air pump 20 is embedded in the first mounting cavity 1131 and its periphery is limited and abutted against the plurality of limiting ribs 117.

[0089] In this embodiment, to ensure that the air pump 20 can be stably confined within the first mounting cavity 1131, multiple limiting ribs 117 are provided on the cavity wall of the first mounting cavity 1131. These limiting ribs 117 are evenly distributed along the inner wall of the first mounting cavity 1131 to match the outer contour of the air pump 20. Each limiting rib 117 provides sufficient support without affecting the smooth insertion of the air pump 20. In addition, the surface of the limiting ribs 117 is usually smoothed to reduce friction and facilitate installation and disassembly. When the air pump 20 is fully embedded in the first mounting cavity 1131, the limiting ribs 117 will conform to the outer wall of the air pump 20, forming multi-point contact, thereby firmly fixing the air pump 20 in the predetermined position. This design not only improves the installation accuracy but also enhances the stability of the air pump 20 in the working state, avoiding loosening or displacement caused by vibration or external impact.

[0090] In one embodiment of this application, an elastic pad can be added to the contact surface between the limiting rib 117 and the air pump 20 to further absorb vibration and reduce noise.

[0091] Referring to Figures 4 and 5, in one embodiment of this application, a second mounting cavity 1141 is further formed inside the outer casing 11. The second mounting cavity 1141 and the first mounting cavity 1131 are arranged at intervals along the axial direction of the air pump 20. The air connector 121 and the water connector 122 are located inside the second mounting cavity 1141. The water replenishment device 1 also includes a battery 73, which is installed inside the second mounting cavity 1141. Multiple air pipes 50 pass through the second mounting cavity 1141 and are respectively connected to the air connector 121 and the water connector 122.

[0092] In this embodiment, the second mounting cavity 1141 and the first mounting cavity 1131 are arranged at intervals along the axial direction of the air pump 20 (that is, as shown in FIG. 4, the second mounting cavity 1141 is located above the first mounting cavity 1131). The second mounting cavity 1141 is mainly used to accommodate the battery 73, the air connector 121 and the water connector 122, as well as related connecting parts. This layout allows different types of components to have their own dedicated space, avoiding mutual interference, and also facilitates maintenance, replacement and installation.

[0093] Both the gas connector 121 and the water connector 122 are located within the second mounting cavity 1141, on the side closest to the nozzle 12. This arrangement not only simplifies the piping layout and reduces unnecessary bends and detours in the gas pipe 50, but also facilitates inspection and maintenance.

[0094] As shown in Figures 2, 4 and 5, in one embodiment of this application, the end of the outer casing 11 facing away from the air pump 20 is recessed to form a mounting groove 112, and the water storage bullet 30 is detachably embedded in the mounting groove 112 and connected to an air pipe 50.

[0095] In this embodiment, the mounting groove 112 is located at the end of the housing 11 opposite to the air pump 20, i.e., at the top of the water replenishment device 1, and is situated on one side of the top of the water replenishment device 1. This layout ensures that the water reservoir 30 does not interfere with the working space of the air pump 20 and other components, while also facilitating user operation and maintenance. Furthermore, when the water reservoir 30 is embedded in the mounting groove 112, it is flush with the outer surface of the housing 11, thereby improving the aesthetic appearance and grip of the water replenishment device 1.

[0096] The water-filled cartridge 30 can be connected to the outer casing 11 via a snap-fit, plug-in, or other quick-connect mechanism, allowing users to easily install or remove it by simply rotating or pressing. This design not only simplifies the operation process but also makes it convenient for users to replace the water-filled cartridge 30 as needed.

[0097] A sealing ring or rubber gasket is installed between the water-retaining bomb 30 and the mounting groove 112 to ensure that there is no liquid leakage during use. The selection of sealing materials must take into account chemical corrosion resistance and elastic recovery ability to adapt to long-term repeated use environments.

[0098] In one embodiment, this application also proposes a water replenishment device 1.

[0099] Referring to Figures 6 and 9, in one embodiment of this application, the water replenishment device 1 includes a housing assembly 10, an air pump 20, a water storage bullet 30, and a control assembly. The housing assembly 10 includes a housing 11 and a nozzle 12. An installation cavity 111 is formed inside the housing 11. The nozzle 12 is installed on the housing 11 and communicates with the installation cavity 111. One end of the nozzle 12 facing the installation cavity 111 is provided with an air connector 121 and a water connector 122. The air pump 20 is installed in the installation cavity 111 and communicates with the air connector 121. The water storage bullet 30 is installed on the housing 11 and communicates with the water connector 122. The control assembly includes a circuit control board 72 and a distance sensor 71. The circuit control board 72 is communicatively connected to the air pump 20 and the water storage bullet 30. The distance sensor 71 is installed on the housing 11 and is communicatively connected to the circuit control board 72.

[0100] Among them, the distance sensor 71 detects the distance between itself and the face, and adjusts the airflow of the air pump 20 and the water flow of the water storage bullet 30 through the circuit control board 72.

[0101] In this embodiment, the outer shell 11 is made of high-strength, lightweight engineering plastic, such as polycarbonate (PC) or plastic. This material not only has good mechanical strength and chemical corrosion resistance, but also ensures the portability of the water replenishment device 1. The air connector 121 and water connector 122 of the nozzle 12 are designed as quick-plug interfaces, which facilitates users to quickly replace the water reservoir 30 and maintain the water replenishment device 1. The air pump 20 is a miniature silent air pump 20 to reduce operating noise and improve the user experience.

[0102] The water-retaining bullet 30 is made of transparent or semi-transparent food-grade silicone or polycarbonate (PC), making it easy for users to observe the remaining amount of hydrating liquid while also ensuring safety when in contact with the skin. The distance sensor 71 is installed on the side of the housing 11 and contacts the external environment through a light-transmitting hole. It can accurately detect the distance to the face and transmit the signal to the circuit control board 72.

[0103] The distance sensor 71 can be a TOF (Time of Flight) sensor, an ultrasonic sensor, or an infrared sensor, etc. This application uses a TOF (Time of Flight) sensor, which calculates the distance between the sensor and the face by emitting a light pulse and measuring the time it takes for the light pulse to return. The TOF sensor features high precision, fast response, and strong anti-interference capabilities, enabling it to measure the distance between the hydration device 1 and the face in real time and accurately.

[0104] The TOF sensor and the circuit control board 72 are connected via a high-speed communication interface, enabling real-time transmission of distance information to the circuit control board 72. Based on the distance information detected by the TOF sensor, the circuit control board 72 dynamically adjusts the airflow of the air pump 20 and the water flow of the water-retaining bullet 30. For example, when the distance between the water replenishment device 1 and the face is detected to be too close, the circuit control board 72 reduces the airflow output power of the air pump 20 and simultaneously reduces the water flow output of the water-retaining bullet 30, thereby reducing the amount of atomization and preventing excessive spraying that could cause user discomfort. Conversely, when the distance is detected to be too far, the circuit control board 72 increases the output of both airflow and water flow, thereby increasing the atomization spray distance to ensure sufficient atomization reaches the face surface.

[0105] Through the cooperation of distance sensor 71 and circuit control board 72, the water replenishment device 1 can dynamically adjust the water replenishment amount according to the distance between the user and the water replenishment device 1, thereby achieving an intelligent water replenishment effect. This design not only improves the accuracy of water replenishment, but also adjusts the atomization effect according to the user's actual needs, avoids wasting water replenishment liquid, and enhances the user experience.

[0106] Referring to Figure 9, in one embodiment of this application, the end of the nozzle 12 that is away from the air connector 121 and the water connector 122 is exposed on one side of the housing 11. The housing 11 has a light-transmitting hole on the side where the nozzle 12 is located. The light-transmitting hole and the nozzle 12 are spaced apart in the vertical direction. The distance sensor 71 is located in the mounting cavity 111 and is positioned towards the light-transmitting hole.

[0107] In this embodiment, the nozzle 12 has a fine nozzle design at its outlet end, which can achieve better atomization and allow the moisturizing liquid to be sprayed evenly on the skin surface. The end of the nozzle 12 that is away from the air connector 121 and the water connector 122 is directly exposed on one side of the housing 11, making it convenient for the user to operate on the face or other areas that need moisturizing.

[0108] The size and shape of the light-transmitting hole are designed according to the size of the light spot emitted by the distance sensor 71 to ensure the efficiency of the distance sensor 71 in emitting and receiving light signals. A light-transmitting plate can also be installed, covering the light-transmitting hole, which not only ensures the light transmission effect of the distance sensor 71 but also provides dust and water protection. The light-transmitting hole and the nozzle 12 are arranged vertically at intervals. This layout not only avoids interference from the spray on the distance sensor 71 but also ensures that the sensor can accurately detect the distance between the water replenishment device 1 and the face.

[0109] In one embodiment of this application, by placing the nozzle 12 and the distance sensor 71 on the same side of the housing 11 and adjacent to each other, the distance from the face detected by the distance sensor 71 to the distance sensor 71 is approximately the distance from the nozzle 12 to the face. Therefore, there is no need to set a compensation value for the distance sensor 71. This layout allows the distance sensor 71 to detect the distance between the nozzle 12 and the face more directly, thereby facilitating the circuit control board 72 to better adjust the amount of water atomization according to the distance.

[0110] As shown in Figures 8 and 9, in one embodiment of this application, the water replenishment device 1 further includes a touch switch 91. The touch switch 91 is disposed in the mounting cavity 111, with one side exposed on the surface of the housing 11 and the other side connected to the circuit control board 72. The touch switch 91 controls the circuit control board 72 to turn on the airflow of the air pump 20 and the water flow of the water storage bomb 30.

[0111] In this embodiment, a touch switch 91 is integrated on the surface of the housing 11 and located on the side of the housing 11 opposite to the nozzle 12, so that the user can easily reach it when holding the water replenishment device 1. The surface of the touch switch 91 is designed to prevent accidental touch, and the operation will only be triggered when the user touches it intentionally, thereby avoiding the problem of accidental activation of the water replenishment device 1 due to accidental touch.

[0112] The internal structure of the touch switch 91 includes a tiny capacitive touch sensing module. This module can detect the minute capacitance changes generated when a user's finger contacts the switch surface and transmit this signal to the circuit control board 72. Furthermore, the touch switch 91 is configured to trigger an activation signal after being pressed for a period of time to prevent accidental activation of the water replenishment device 1 due to user touch. Upon receiving the signal, the circuit control board 72 immediately activates the air pump 20 and the water flow from the water reservoir 30, initiating the operation of the water replenishment device 1. When the user touches the touch switch 91 again, the circuit control board 72 stops the air pump 20 and the water flow, thus putting the water replenishment device 1 into standby mode.

[0113] In terms of material selection, the surface of the touch switch 91 is made of high-strength transparent polycarbonate (PC) material, which not only has good wear resistance and scratch resistance, but also ensures the sensitivity of the touch sensing module. At the same time, the other parts of the housing 11 also use the same material to maintain the overall aesthetics and consistency of the water replenishment device 1.

[0114] By adding a touch switch 91, the water replenishment device 1 in this embodiment achieves a more convenient operation. Users can start or stop the water replenishment device 1 simply by lightly touching the touch switch 91 on the surface of the housing 11. This design not only improves the convenience of operation but also enhances the user's intelligent user experience of the water replenishment device 1.

[0115] Referring to Figures 8 and 9, in one embodiment of this application, the water replenishment device 1 further includes a touch adjustment component 92. The touch adjustment component 92 is disposed in the mounting cavity 111. One side of the touch adjustment component 92 is exposed on the surface of the housing 11 and is combined with the touch switch 91 to form a touch panel 90. The other side of the touch adjustment component 92 is communicatively connected to the circuit control board 72. Touching the touch adjustment component 92 in different directions can increase or decrease the amount of mist of the water replenishment liquid through the circuit control board 72.

[0116] In this embodiment, the touch adjustment component 92 and the touch switch 91 together form an integrated touch panel 90. This panel is located on the side of the housing 11 and is positioned opposite the nozzle 12, facilitating operation by the user when holding the water replenishment device 1. The touch adjustment component 92 employs capacitive touch sensing technology, capable of detecting the sliding direction and amplitude of the user's finger and transmitting this information to the circuit control board 72. Based on the received signals, the circuit control board 72 dynamically adjusts the airflow of the air pump 20 and the water flow of the water storage bullet 30, thereby regulating the amount of water replenishment mist.

[0117] Users can adjust the amount of mist by sliding their fingers up and down on the surface of the touch-sensitive adjustment element 92. For example, sliding the finger up increases the output of airflow and water flow on the circuit control board 72, thereby increasing the amount of mist; sliding the finger down decreases the output of airflow and water flow on the circuit control board 72, thereby decreasing the amount of mist. This design is not only intuitive to operate, but also allows users to flexibly adjust the amount of mist according to different usage scenarios and personal preferences.

[0118] By adding a touch-sensitive adjustment component 92, the water replenishment device 1 in this embodiment achieves precise adjustment of the spray volume. Users can adjust the mist volume through simple sliding operations according to different usage scenarios and personal preferences. This design not only improves the flexibility and user experience of the water replenishment device 1, but also makes the water replenishment device 1 more intelligent.

[0119] As shown in Figures 6, 7 and 9, in one embodiment of this application, the water replenishment device 1 further includes a display screen 80. The display screen 80 is disposed on the surface of the housing 11 and is located on the same side of the housing 11 as the nozzle 12. The display screen 80 is communicatively connected to the control component and displays the control parameters of the control component and the amount of water replenishment liquid.

[0120] Alternatively, the control assembly may also include a power switch 74 and a battery 73. The battery 73 is installed in the mounting cavity 111 and is electrically connected to the control assembly and the air pump 20. The power switch 74 is installed in the housing 11 and is exposed on the side of the housing 11 where the nozzle 12 is located. The power switch 74 is electrically connected to the battery 73 and controls the electrical connection or disconnection between the battery 73 and the control assembly and the air pump 20.

[0121] In this embodiment, the display screen 80 is a small liquid crystal display screen 80 (LCD) or organic light-emitting diode display screen 80 (OLED), mounted on the side of the housing 11, on the same side as the nozzle 12. This layout not only makes it convenient for users to view information when operating the water replenishment device 1, but also maintains the overall aesthetics of the water replenishment device 1.

[0122] The display screen 80 is connected to the control components (including the circuit control board 72 and the distance sensor 71) via internal circuitry, and can receive and display the following information in real time:

[0123] Current mist volume: Displays the current mist volume level output by the air pump 20 and water tank 30, for example, as a percentage (e.g., 50%) or a graphical progress bar.

[0124] Distance sensor 71 data: Displays the real-time distance between the hydration device 1 and the face, for example, in centimeters.

[0125] Water Reservoir 30 Remaining Water Level: The transparent water reservoir 30 design, combined with the percentage or graphical display on the screen 80, allows users to intuitively understand the remaining amount of water replenishment.

[0126] Water replenishment device 1 status: Displays the current working status of water replenishment device 1, such as "standby", "running" or "low battery".

[0127] The surface of the display screen 80 is made of scratch-resistant and fingerprint-resistant glass or polycarbonate material, and covered with a transparent protective film to ensure the clarity and durability of the displayed content. In addition, a ring-shaped indicator light is provided around the display screen 80 to provide auxiliary illumination in low-light environments, ensuring that users can clearly view information.

[0128] To further enhance the user experience, the display 80 also features automatic brightness adjustment. Through a built-in photosensor, the display 80 can automatically adjust its brightness according to the intensity of ambient light, maintaining clear readability in bright light while reducing eye strain in low-light environments.

[0129] With or without limitation including a display screen 80 in the water replenishment device 1, the inclusion of a power switch 74 and a battery 73 provides the water replenishment device 1 with an independent power supply system, thereby improving its portability and ease of use. The battery 73 is a high-capacity, rechargeable lithium-ion battery, installed within the mounting cavity 111, and connected to the control components and air pump 20 via internal circuitry. This design not only ensures stable power supply to all components but also reduces reliance on external power sources, enabling the water replenishment device 1 to be used anytime, anywhere.

[0130] The power switch 74 is designed as a small physical button, mounted on the side of the housing 11 where the nozzle 12 is located, so that the user can easily reach it when holding the water replenishment device 1. The power switch 74 is electrically connected to the battery 73, and controls the electrical conduction or disconnection between the battery 73 and the control components and the air pump 20 to turn the water replenishment device 1 on and off.

[0131] To further enhance the user experience, a ring-shaped indicator light is also installed around the power switch 74. When the water replenishment device 1 is in the off state, the indicator light flashes a faint red light; when the water replenishment device 1 is on, the indicator light turns bright green and remains on. This visual feedback mechanism allows users to intuitively understand the current status of the water replenishment device 1.

[0132] In addition, a Type-C charging port is provided on the side or bottom of the outer casing 11. The Type-C charging port connects to the battery, so users can use a Type-C charger or power bank to charge the water replenishment device 1. When the battery 73 is low on power, the display screen 80 will show a low battery icon and flash an indicator light to remind the user to charge it in time. The water replenishment device 1 is also equipped with a buzzer, which is located on the outer casing 11 and communicates with the control component. When the water replenishment device 1 is low on power, or the liquid level is insufficient, or the amount of mist sprayed from the nozzle is too large or too small, the buzzer will sound an alarm to provide a warning.

[0133] In one embodiment of this application, the buzzer is provided with multiple sound modes, including different volume levels and frequencies.

[0134] Low battery mode: Medium volume (to avoid disturbing the user with excessive loudness), low frequency (such as 400Hz), with a steady sound, while emitting continuous short "beep" sounds, such as "beep-beep-beep" (3 times per second), to indicate that the battery is low and needs to be charged in time.

[0135] Low fluid level mode: Medium volume, mid-frequency (e.g., 800Hz), clear, long-interval "beep" sounds, such as "beep...beep...beep" (once every 3 seconds), indicating that the fluid level is low and needs to be added promptly. (The mid-frequency sound is easy to identify, and the long intervals give the user enough time to address the issue.)

[0136] Excessive Fog Volume Mode: A higher volume (ensuring the user can hear it even in noisy environments), high-frequency (e.g., 1200Hz), sharp, continuous, rapid "beep" sounds, such as "beep beep beep beep" (5 times per second), to indicate excessive fog volume, which may affect usability or safety. (The high-frequency, sharp sound is likely to alert the user, and the rapid rhythm prompts them to adjust the fog volume promptly.)

[0137] Low mist volume mode: Low volume (to avoid excessive interference), low frequency (such as 300Hz), low and slow "beep" sound, such as "beep...beep...beep" (once every 5 seconds), to indicate that the mist volume is too low, which may affect the hydration effect.

[0138] The above modes are merely prompt modes for the applicant to use a buzzer to distinguish different states of the water replenishment device. However, when the water replenishment device 1 is in different states, the buzzer is not limited to the corresponding modes and the specific sound volume and frequency of the above modes.

[0139] To further enhance the user experience, the buzzer's sound mode can be combined with other prompts, such as: LED indicator: flashing synchronously with the sound mode to enhance the prompting effect; screen display: displaying specific status information (such as "low battery" or "excessive mist") on the water replenishment device's display screen 80; vibration prompt: adding a vibration function as an auxiliary prompt for users with hearing impairments.

[0140] Referring to Figures 9, 11, and 12, in one embodiment of this application, the water replenishment device 1 further includes a connecting pipe 60, which is disposed in the mounting cavity 111. One end of the connecting pipe 60 is provided with a water inlet connector 61, and the other end is provided with a water outlet connector 62 and an air valve connector 63. The water inlet connector 61 is connected to the water storage bomb 30, and the water outlet connector 62 is connected to the water circuit connector 122. The surface of the outer shell 11 is provided with an air hole 114 that connects to the mounting cavity 111. The air valve connector 63 is connected to the air hole 114 through an air pipe 50.

[0141] In this process, the air pressure generated by the air pump 20 passes through the nozzle 12, the connecting pipe 60, and the air pipe 50 in sequence, and is finally discharged from the air hole 114 to clean the air and water passages inside the water replenishment device 1.

[0142] In this embodiment, the connecting tube 60 can be made of flexible or rigid materials, such as medical-grade silicone tubes or polycarbonate (PC) tubes, to ensure its safety and durability during use.

[0143] The inlet connector 61 and outlet connector 62 are designed to ensure a tight connection between the connecting pipe 60 and the water reservoir 30 and nozzle 12. The inlet connector 61 can be designed as a quick-connect interface, allowing for easy connection and disconnection when the user replaces the water reservoir 30. The outlet connector 62 connects to the water connector 122 of the nozzle 12 via a plug or through the air pipe 50, ensuring no leakage during use.

[0144] In one embodiment of this application, the connection between the water inlet connector 61 and the water storage chamber 33 of the water storage bullet 30 can be designed as a sealed structure, such as using an O-ring or rubber gasket, to prevent water leakage. A similar sealing design can also be used at the connection between the water outlet connector 62 and the water passage connector 122 of the nozzle 12 to ensure stable water flow transmission under high pressure.

[0145] By introducing the connecting pipe 60, the internal fluid transmission of the water supply device 1 becomes more efficient and stable. The design of the connecting pipe 60 not only simplifies the internal structure and reduces the complexity of the piping, but also facilitates the connection between the water storage cartridge 30 and the nozzle 12. When replacing the water storage cartridge 30, the user can simply plug and unplug the connecting pipe 60 to complete the connection and disconnection operations, significantly improving the convenience of use.

[0146] The connecting pipe 60 is provided with a water outlet connector 62 at one end and an air valve connector 63 at the other end. The water replenishment device 1 also includes a pneumatic element. The pneumatic element is located in the mounting cavity 111 and is connected to the outside of the outer shell 11 at one end and to the air valve connector 63 at the other end. The pneumatic element provides air pressure and drives the replenishment liquid in the water storage cavity 33 to enter the water circuit connector 122 through the water outlet connector 62.

[0147] In this embodiment, the pneumatic component provides stable air pressure and drives the replenishing liquid in the water storage chamber 33 to enter the water circuit connector 122 through the water outlet connector 62, and finally mixes with the airflow at the nozzle 12 and is atomized and sprayed out. The pneumatic component can be a miniature air pump 20 or a pneumatic valve, depending on the size of the water replenishment device 1 and the user's requirements. The air valve connector 63 and the pneumatic component are connected by an air pipe 50. The surface of the outer shell 11 has air holes 114, and the pneumatic component is connected to the air holes 114 through the air pipe 50 to achieve air pressure balance inside the pneumatic component.

[0148] The pneumatic components and air valve connector 63, in addition to driving the replenishing liquid in the water storage chamber 33 into the nozzle 12, can also realize the self-cleaning function of the water replenishment device 1. For example, when it is necessary to clean the fluid pipe inside the water replenishment device 1, the air pump 20 is turned on and the nozzle 12 is blocked by hand. At this time, the air pressure of the air pump 20 will be discharged through the air connector 121, the nozzle 12, the water connector 122, the water outlet connector 62, the connecting pipe 60, the air valve connector 63, the pneumatic components, and finally through the air hole 114 opened on the surface of the outer shell 11, thereby realizing the self-cleaning of the water replenishment device 1.

[0149] To ensure the stability and reliability of pneumatic components, an internal filter can be installed to remove impurities and moisture from the air. Furthermore, the pneumatic components can be equipped with a pressure regulator, allowing users to adjust the air pressure as needed, thereby controlling the atomization effect of the makeup water.

[0150] By introducing pneumatic components and an air valve connector 63, the atomization effect of the water replenishment device 1 is significantly improved. The stable air pressure provided by the pneumatic components effectively propels the replenishing liquid through the connecting pipe 60 to the nozzle 12, where it mixes with the airflow and is then atomized and sprayed out. This design not only improves the transmission efficiency of the replenishing liquid but also enhances the stability and reliability of the water replenishment device 1. Furthermore, the introduction of pneumatic components provides users with a more flexible operating experience. Users can control the atomization effect of the replenishing liquid by adjusting the air pressure according to different usage scenarios and personal preferences. This design is particularly suitable for occasions requiring different atomization intensities, significantly improving the user experience.

[0151] As shown in Figures 9 and 10, in one embodiment of this application, two air pumps 20 are provided. The two air pumps 20 are spaced apart in the mounting cavity 111 along a direction perpendicular to the axial direction of the air pumps 20, and are located at the end of the housing 11 away from the nozzle 12 and the water storage bullet 30. Both air pumps 20 are connected to the air passage connector 121.

[0152] And / or, the control component also includes a communication module, which is located in the mounting cavity 111 and is connected to the circuit control board 72. The communication module is used to communicate with the mobile terminal, which sends control signals to the circuit control board 72 through the communication module and adjusts the amount of water mist.

[0153] Because this application incorporates two air pumps 20, the required air pressure for a single air pump 20 is lower. Consequently, the volume occupied by a single air pump 20 in the first mounting cavity 111 is smaller. This facilitates the rational arrangement of the air pumps 20 according to the shape of the internal components and the available space of the water replenishment device 1, thus meeting the requirements for miniaturization and compactness. This design not only optimizes the internal structure and reduces assembly space but also better adapts to the personalized needs of different users. Furthermore, the independent operating characteristics of each air pump 20 allow for series or parallel connection between them. Even if one air pump 20 fails, the other air pump 20 can continue to operate, ensuring the stability and reliability of the water replenishment device 1.

[0154] The two air pumps 20 are placed parallel to each other on the same horizontal line, maintaining an appropriate distance. This layout ensures that each air pump 20 has sufficient installation space without interfering with each other, while avoiding heat conduction problems or resonance that may be caused by close proximity. The spacing also helps with heat dissipation, extending the service life of the air pumps 20.

[0155] The two air pumps 20 can be configured with different specifications or the same specifications. For example, as shown in Figure 9 of this embodiment, the two air pumps 20 are selected with the same specifications and size, and the two air pumps 20 are set at the bottom of the water replenishment device 1, that is, at the end of the outer shell 11 away from the nozzle 12 and the water storage bullet 30. Since the air pumps 20 are relatively heavy, this design can improve the grip of the water replenishment device 1 during use and improve the stability when placed. In addition, since the two air pumps 20 have the same or similar weight, when the two air pumps 20 are spaced apart in a direction perpendicular to the axial direction of the air pumps 20, the two air pumps 20 can be set in a left-right symmetrical structure within the first mounting cavity 111 to further improve the stability of the structure and the grip. At the same time, this symmetrical structural design can also further improve the space utilization inside the outer shell 11 and facilitate the layout of the structure.

[0156] Additionally, when the water replenishment device 1 is operating and the required air pressure for atomization is low, both air pumps 20 can be configured to output lower power, or only one air pump 20 can be controlled to operate. For example, one air pump 20 can be used as the main drive source to generate the basic airflow; the other can act as an auxiliary pressurization unit to further pressurize the airflow, ultimately forming a stable high-pressure airflow to drive the liquid for atomization. This method not only provides a higher pressure range but also allows for flexible adjustment of the output power according to actual needs. For example, in low-power mode, only the main air pump 20 operates; while in high-power mode, both air pumps 20 work together to achieve a stronger spray effect. Of course, both air pumps 20 can also be set to output power simultaneously in both low-power and high-power modes.

[0157] Each air pump 20 is mounted on a base with elastic support, which can absorb and disperse vibration energy to a certain extent, reduce the vibration intensity transmitted to other components, and reduce noise generation.

[0158] In one embodiment of this application, a layer of sound-insulating material is wrapped around the air pump 20, which effectively reduces the noise generated during operation and improves the user experience.

[0159] When there are two air pumps 20, the control component may or may not be limited to two. The control module also includes a communication module, which can be a wireless communication module such as a Bluetooth connection module or a Wi-Fi connection module, or a wired communication module such as a USB connection module or an Ethernet connection module. In this embodiment, the communication module uses a Bluetooth connection module, and the mobile terminal is a mobile phone, tablet, or other device. After connecting the Bluetooth connection module by rotating the device, interaction between the mobile terminal and the water replenishment device 1 can be achieved. The user can view the current water replenishment volume of the water storage bullet 30, the remaining power of the battery 73 of the water replenishment device 1, and the amount of mist produced by the water replenishment device when it is working on the mobile phone. Simultaneously, the user can also control and adjust the amount of mist produced by the nozzle 12 of the water replenishment device 1 through a mobile phone APP. For example, when the amount of mist is small, the user can send a control command through the APP. The control command is transmitted to the circuit control board 72 via the Bluetooth connection module, and the circuit control board 72 adjusts the airflow of the air pump 20 and the water flow of the water storage bullet 30, thereby increasing or decreasing the amount of mist produced by the water replenishment device. By setting up a Bluetooth module, users can not only keep track of the current parameters of the water replenishment device 1, but also control and adjust the water replenishment effect of the water replenishment device 1 through a mobile terminal, thereby improving the intelligence level of the water replenishment device 1 and the user experience.

[0160] Referring to Figure 9, in one embodiment of this application, the air outlet of one air pump 20 is connected to the air inlet of another air pump 20 through an air pipe 50, and the air outlet of the other air pump 20 is connected to the air connector 121 through another air pipe 50.

[0161] In this embodiment, the two air pumps 20 are connected in series. Specifically, the first air pump 20 initially compresses the air, and then the compressed gas is transmitted to the second air pump 20 for secondary pressurization through the air pipe 50. Finally, the high-pressure airflow after double compression flows out from the outlet of the second air pump 20 and directly reaches the nozzle 12 through the air pipe 50, forming a powerful atomization force. This design allows the first air pump 20 to run independently during the startup phase, and the second air pump 20 to be turned on after the pressure stabilizes, avoiding the impact of a sudden large current on the circuit system. Furthermore, this series connection of the two air pumps 20 not only facilitates multi-level adjustment functions but also reduces the workload of a single air pump 20, extending the service life of the water replenishment device 1.

[0162] As shown in Figure 10, in one embodiment of this application, the water replenishment device 1 further includes a three-way pipe 23, the air outlets of the two air pumps 20 are respectively connected to two channels of the three-way pipe 23, and the other channel of the three-way pipe 23 is connected to the air connector 121 through the air pipe 50.

[0163] In this embodiment, the two air pumps 20 are connected in parallel via a three-way pipe 23. The three-way pipe 23 can be Y-shaped or T-shaped. The inner surface of the three-way pipe 23 is specially treated to be smooth and burr-free, ensuring smooth airflow and facilitating daily cleaning and maintenance. To adapt to different operating environments, the three-way pipe 23 can be made of high-pressure resistant and corrosion-resistant materials, such as high-strength plastics or metal alloys, to ensure long-term stable operation. The airflow generated by the two air pumps 20 converges at the three-way pipe 23 after entering, forming a higher and more uniform airflow.

[0164] This design, which utilizes a three-way pipe 23 to connect two air pumps 20 in parallel, solves the problem of traditional hydration devices 1 struggling to coordinate the synchronous operation of multiple air pumps 20, achieving effective integration and optimized distribution of airflow. Users can easily switch between different speeds according to their actual needs, obtaining a more stable and efficient skincare experience.

[0165] Referring to Figures 9 and 10, in one embodiment of this application, one end of the air pump 20 connected to the air passage connector 121 is the first end 21, and the other end of the air pump 20 is the second end 22. The cross-sectional dimension of the first end 21 is larger than that of the second end 22. The cavity wall of the first mounting cavity 111 is provided with a limiting step. The second end 22 is inserted into the first mounting cavity 111, and the first end 21 abuts against the limiting step.

[0166] In this embodiment, one end (first end 21) of the air pump 20 is designed with a larger cross-sectional size, while the other end (second end 22) is relatively smaller. This stepped design can provide clear directional guidance during installation and prevent reverse installation or misoperation.

[0167] The first mounting cavity 111 has a dedicated limiting step on its cavity wall, or the first mounting cavity 111 can also be set in a stepped shape to adapt the shape of the first mounting cavity 111 to the air pump 20. When the air pump 20 is inserted into the first mounting cavity 111, the first end 21 abuts against the limiting step, and the second end 22 abuts against the bottom wall of the first mounting cavity 111, together providing physical support for the air pump 20. The presence of the limiting step also allows the air pump 20 to maintain a stable position when subjected to external impact or vibration, reducing the risk of loosening or displacement.

[0168] As shown in Figures 6-8, in one embodiment of this application, one end of the outer shell 11 is recessed to form a mounting groove 112. The shape of the mounting groove 112 is adapted to the water storage bullet 30, and the water storage bullet 30 is detachably embedded in the mounting groove 112.

[0169] In this embodiment, the shape of the mounting groove 112 closely matches the shape of the water-storing bullet 30, ensuring that the water-storing bullet 30 can be tightly embedded and remain stable. For example, the shapes of the mounting groove 112 and the water-storing bullet 30 can be cylindrical, elliptical, or cuboid, etc., and the specific dimensions are determined according to actual needs.

[0170] The connection between the water-storage cartridge 30 and the mounting slot 112 can employ various design schemes. One implementation method is a snap-fit ​​connection, where the outer side of the water-storage cartridge 30 has an elastic snap-fit ​​structure, and the inner side of the mounting slot 112 has a corresponding slot. When the water-storage cartridge 30 is inserted into the mounting slot 112, the elastic snap-fit ​​automatically engages with the slot, achieving a secure connection. This connection method is simple to operate; the user only needs to press lightly to complete the installation or removal.

[0171] Another implementation method is to use a threaded connection. The outer side of the water-retaining cartridge 30 has external threads, and the inner side of the mounting groove 112 has internal threads. By tightening the threads, the water-retaining cartridge 30 and the outer casing 11 can be tightly connected. The advantages of the threaded connection are that the connection is firm and the sealing performance is good, making it particularly suitable for occasions where the water-retaining cartridge 30 needs to be frequently replaced.

[0172] The installation groove 112 design makes the installation and removal of the water storage cartridge 30 more convenient. Users can quickly replace the water storage cartridge 30 without complicated operations, significantly improving the ease of use of the water replenishment device 1. At the same time, the tight fit design between the installation groove 112 and the water storage cartridge 30 ensures the stability of the water storage cartridge 30 during use and avoids leakage problems caused by loosening or displacement.

[0173] To further enhance the performance and user experience of the water replenishment device 1, the wall of the mounting groove 112 can be fitted with an anti-slip texture or rubber pad to increase the friction between the water reservoir 30 and the outer casing 11, preventing the water reservoir 30 from loosening due to vibration or external force. Simultaneously, the rubber pad also acts as a buffer, reducing wear on the water reservoir 30 during installation and disassembly.

[0174] When the water-storage bomb 30 is installed in the mounting slot 112, there is a smooth transition between the outer surface of the water-storage bomb 30 and the outer surface of the outer shell 11.

[0175] In this embodiment, the mounting groove 112 and the nozzle 12 are both located at the same end of the outer casing 11, and the mounting groove 112 and the nozzle 12 are positioned opposite each other on both sides of the outer casing 11. The mounting groove 112 is located at a side corner of the outer casing 11. The outer casing 11 has rounded chamfers on all four sides, allowing the water-retaining bullet 30 to conform to the shape of the mounting groove 112. When the water-retaining bullet 30 is installed in the mounting groove 112, the surface of the water-retaining bullet 30 smoothly transitions to the surface of the outer casing 11. Furthermore, the surface of the water-retaining bullet 30 exposed on the outer side of the outer casing 11 is also a rounded surface. This design makes the overall appearance of the water-replenishing device 1 simpler and more aesthetically pleasing, enhancing the product's perceived quality. Simultaneously, this design also enhances user comfort during use and carrying, avoiding inconvenience caused by the water-retaining bullet 30 protruding or recessed. For example, when holding the water-replenishing device 1, the user will not feel a noticeable gap between the water-retaining bullet 30 and the outer casing 11, thus improving grip comfort.

[0176] As shown in Figures 7 and 8, in one embodiment of this application, a guide block 113 protrudes from the side wall of the mounting groove 112, and a guide groove 31 is provided on one side of the water storage bullet 30. The guide block 113 slides in the guide groove 31 and guides the water storage bullet 30 to be embedded in the mounting groove 112.

[0177] In this embodiment, a guide block 113 protrudes from the side wall of the mounting groove 112, and a guide groove 31 adapted to the guide block 113 is formed on one side of the water-storing bullet 30. The guide block 113 and the guide groove 31 are designed to guide the water-storing bullet 30 to slide along a predetermined trajectory during installation, ensuring that the water-storing bullet 30 can be accurately and smoothly embedded into the mounting groove 112. The guide block 113 can be trapezoidal, semi-circular, elongated, or other shapes suitable for sliding to reduce friction during installation and provide stable guidance. The depth and width of the guide groove 31 are adjusted according to the size of the guide block 113 to ensure that the two can fit tightly together. This design not only improves the convenience of installation but also reduces the risk of damage to the water-storing bullet 30 due to improper installation.

[0178] In one embodiment of this application, guide blocks 113 are provided on both sides of the mounting groove 112, and guide grooves 31 are also provided on both sides of the water storage bullet 30. Each guide block 113 is slidably disposed in a guide groove 31, which not only improves the convenience of installing the water storage bullet 30, but also extends along the direction in which the water storage bullet 30 is inserted into the mounting groove 112. Therefore, the guide blocks 113 and guide grooves 31 also play a limiting role for the water storage bullet 30 along the direction perpendicular to the insertion direction, thereby improving the stability of the water storage bullet 30.

[0179] As shown in Figures 11 and 12, in one embodiment of this application, the water replenishment device 1 further includes an unlocking component 40, which includes an unlocking key 41, a connecting block 43, and an elastic element 42.

[0180] The water storage bullet 30 has a slot 32 on its side, the elastic element 42 is located in the mounting cavity 111, one end of the connecting block 43 is elastically abutting against the elastic element 42, and the other end is provided with a plug 44. One end of the unlocking key 41 is connected to the connecting block 43, and the other end is exposed on the outer surface of the outer shell 11.

[0181] The elastic element 42 drives the connecting block 43 to insert the insert block 44 into the slot 32, so that the water storage bullet 30 is fixed in the mounting groove 112; the moving unlock key 41 drives the connecting block 43 to compress the elastic element 42, and drives the insert block 44 to separate from the slot 32, so that the water storage bullet 30 is separated from the outer shell 11.

[0182] The unlocking component 40 can be designed as a sliding button or a rotating button, installed on the side or top of the housing 11. Users can control the movement of the unlocking component 40 through simple sliding or rotating operations, thereby dismantling the water-filled bullet 30.

[0183] The design of the unlocking component 40 makes the disassembly of the water-retaining bullet 30 simpler and faster. Users do not need tools or complicated procedures; they can disassemble the water-retaining bullet 30 simply by moving the unlocking component 40. This design significantly improves user convenience and reduces the risk of damage to the water-retaining bullet 30 due to improper disassembly.

[0184] In one embodiment of this application, a slot 32 adapted to the insert block 44 is provided on one side of the water storage bullet 30. The direction in which the insert block 44 is inserted into the slot 32 is perpendicular to the direction in which the water storage bullet 30 is inserted into the mounting groove 112. Therefore, when the insert block 44 is inserted into the slot 32, the insert block 44 limits the water storage bullet 30 along the moving direction of the water storage bullet 30. Combined with the limiting of the guide block 113 and the guide groove 31, the water storage bullet 30 can be stably held in the mounting groove 112.

[0185] The end of the insert 44 is chamfered. This chamfer design allows the insert 44 to be inserted into the slot 32 more smoothly, thus achieving a stable connection between the water-retaining bullet 30 and the outer casing 11. The angle of the chamfer can be adjusted according to actual needs, generally designed as 45° or 30°, to ensure that the insert 44 can slide smoothly into the slot 32. At the same time, the inner wall of the slot 32 can be designed as an inclined slope or a curved surface so that the insert 44 can automatically align and smoothly enter the slot 32 during insertion.

[0186] The unlock button 41 can be designed as a sliding button or a push button, mounted on the side or top of the housing 11 for easy user operation. The connecting block 43 transmits the action of the unlock button 41 to the insert 44, while the elastic element 42 provides the necessary elastic restoring force to ensure that the insert 44 can automatically reset after unlocking, and to ensure that the insert 44 can be stably inserted into the slot 32 when locked. The elastic element 42 can be a spring or other elastic material, such as rubber or elastic plastic.

[0187] The connection between the unlock button 41 and the connecting block 43 can be mechanically fixed, such as by screws, clips, or plugs. The other end of the connecting block 43 has a plug 44, the shape and size of which are adapted to the slot 32 on the water-storing bullet 30. When the unlock button 41 is moved, the connecting block 43 moves accordingly, compressing the elastic element 42, and simultaneously pulling the plug 44 out of the slot 32, completing the unlocking action.

[0188] In one embodiment of this application, as shown in FIG12, the end of the unlock button 41 facing the connecting block 43 has a chamfered surface. The chamfered surface is an inclined surface or a curved surface. By setting the chamfered surface, the cross-sectional dimension of the unlock button 41 gradually decreases in the direction toward the connecting block 43. The connecting block 43 has an inclined surface or curved surface that matches the chamfered surface. The two fit together. When the unlock button 41 is pressed, the chamfered surface drives the connecting block 43 to move in the direction toward the compression spring, while the insert 44 is pulled out from the slot 32. In addition, a limiting hole is also provided on the connecting block 43. A limiting block protrudes from the end face of the unlock button 41. The limiting block is at least partially embedded in the limiting hole. The limiting hole extends in the direction of pressing the unlock button 41, so that the connecting block 43 limits the unlock button 41 through the limiting hole, thereby improving the stability of the unlock button 41 when it is pressed and moved.

[0189] As shown in Figure 12, in one embodiment of this application, the water storage bullet 30 has a water outlet 34 at one end facing the mounting cavity 111, and the water replenishment device 1 also includes a sealing member 35. One end of the sealing member 35 is disposed in the water storage cavity 33, and the other end is elastically connected to the end of the water storage bullet 30.

[0190] When the water-storage cartridge 30 is removed from the outer casing 11, the seal 35 blocks the water outlet 34; when the water-storage cartridge 30 is installed on the outer casing 11, the water inlet connector 61 presses against and drives the seal 35 to move toward the inside of the water storage cavity 33 to open the water outlet 34.

[0191] In this embodiment, the seal 35 can be made of an elastic material, such as silicone or rubber, to ensure good elasticity and sealing performance during use. The shape of the seal 35 can be adjusted according to the size of the water outlet 34, for example, designed as a circle or an ellipse, to ensure a tight fit with the water outlet 34. The diameter of the water outlet 34 can be adjusted according to the capacity of the water storage cartridge 30 and the flow rate requirement of the nozzle 12 to ensure that the replenishing liquid can flow out smoothly. The elastic connection part of the seal 35 can be designed as a small spring or an elastic rubber ring to provide the necessary elastic force so that the seal 35 can automatically seal the water outlet 34 when the water storage cartridge 30 is removed.

[0192] When the water reservoir 30 is installed on the housing 11, the water inlet connector 61 contacts the seal 35 and applies pressure. The design of the water inlet connector 61 should ensure that it can smoothly press against the seal 35, causing it to move towards the interior of the water storage cavity 33, thereby opening the water outlet 34. The water inlet connector 61 can be cylindrical, with a diameter smaller than that of the water outlet 34, to ensure that after the seal 35 opens the water outlet 34, the replenishing fluid in the water storage cavity 33 can flow smoothly into the connecting pipe 60. When the water reservoir 30 is removed from the housing 11, the elastic force generated by the elastic part of the seal 35 will push the seal 35 back to its original position, thereby sealing the water outlet 34 and preventing the replenishing fluid from leaking.

[0193] This design not only prevents leakage of the replenishing fluid during storage and transportation but also improves the sealing performance and service life of the water reservoir 30. The elastic design of the seal 35 ensures its reliability and stability during use, while providing users with a more convenient user experience. During the installation and removal of the water reservoir 30, the seal 35 can automatically adjust its position to ensure the opening and closing of the water outlet 34. This design is particularly suitable for applications requiring frequent replacement of the water reservoir 30, significantly enhancing the user experience.

[0194] In one embodiment, this application also proposes a water replenishment device 1, aiming to solve the problems of low efficiency and easy leakage when replacing the replenishing fluid in existing water replenishment devices 1. Traditional water replenishment devices 1 typically have a water inlet in their water storage chamber 33, through which the user needs to inject the replenishing fluid. However, this design is not only cumbersome to operate, but also prone to leakage of the replenishing fluid during the filling process, affecting the user experience. To overcome these shortcomings, this application improves the water replenishment device 1.

[0195] Referring to Figures 13 to 16, in one embodiment of this application, the water replenishment device 1 includes a housing assembly 10, an air pump 20, and a water storage bullet 30. The housing assembly 10 includes a housing 11 and a nozzle 12. An installation cavity 111 is formed inside the housing 11. The nozzle 12 is installed in the housing 11 and communicates with the installation cavity 111. The nozzle 12 includes a body and an air connector 121 and a water connector 122 located at one end of the body facing the installation cavity 111 and communicating with the body. The air pump 20 is located in the installation cavity 111 and communicates with the air connector 121. A water storage chamber 33 is formed inside the water storage bullet 30. The water storage chamber 33 is filled with water replenishment liquid. The water storage bullet 30 is detachably installed in the housing 11. When the water storage bullet 30 is installed in the housing 11, the water storage chamber 33 communicates with the water connector 122. When the water storage bullet 30 is removed from the housing 11, the water storage chamber 33 is in a self-sealing state.

[0196] The core design feature of this application lies in the detachability and self-sealing characteristics of the water-replenishing cartridge 30. When the replenishing fluid inside the water-replenishing cartridge 30 is depleted, the user does not need to refill it through the inlet; instead, they can directly remove the water-replenishing cartridge 30 from the outer casing 11 and replace it with a new one. Since the unused water-replenishing cartridge 30 is in a self-sealing state, it effectively prevents leakage of the replenishing fluid during storage and transportation, making it convenient for users to carry. This improvement not only increases the efficiency of replacing the replenishing fluid in the water-replenishing device 1 but also avoids the problem of replenishing fluid leakage, significantly enhancing the user experience.

[0197] In one embodiment of this application, the outer shell 11 may be made of high-strength, lightweight engineering plastics or metals, such as polycarbonate (PC) or polylactic acid (PLA), to ensure the durability and portability of the device. The air connector 121 and water connector 122 of the nozzle 12 may be designed as quick-plug interfaces, facilitating quick replacement of the water reservoir 30 and maintenance of the device. Furthermore, the air pump 20 may be a miniature, silent air pump to reduce operating noise and improve the user experience. The hydrating liquid inside the water reservoir 30 mixes with the airflow provided by the air pump 20, is atomized inside the nozzle 12, and then sprayed onto the face surface to achieve hydration. The outlet of the nozzle 12 may be configured with fine nozzle holes to achieve better atomization, allowing the hydrating liquid to be sprayed evenly onto the skin surface.

[0198] The water storage chamber 33 of the water storage cartridge 30 can be designed in a cylindrical or elliptical shape to accommodate different capacity requirements and ensure smooth flow of the makeup water. Furthermore, the self-sealing design of the water storage cartridge 30 is achieved by setting an elastic seal 70 at its outlet. When the water storage cartridge 30 is installed on the housing 11, the inlet connector 61 presses against the seal 70, causing it to move into the water storage chamber 33, thereby opening the outlet 34 and allowing the makeup water to flow out. When the water storage cartridge 30 is removed from the housing 11, the seal 70 automatically resets under its own elasticity, sealing the outlet 34 and preventing makeup water leakage. This design not only improves the sealing performance of the equipment but also extends the service life of the water storage cartridge 30. Alternatively, a sealing diaphragm can be installed at the end of the water storage cartridge 30. When the water storage cartridge 30 is installed on the housing 11, the inlet connector 61 penetrates the sealing diaphragm to allow the makeup water to flow out.

[0199] The water-storing cartridge 30 can be connected to the outer casing 11 in various ways. For example, the water-storing cartridge 30 can be connected to the outer casing 11 by plugging it in, which is simple and easy for users to operate. Alternatively, it can be connected to the outer casing 11 by a snap-fit ​​mechanism. The snap-fit ​​can be designed as an elastic snap-fit, allowing for quick installation and removal of the water-storing cartridge 30 through elastic deformation. Of course, a threaded connection can also be used, with external threads on the outer side of the water-storing cartridge 30 and internal threads on the inner side of the mounting groove 112 of the outer casing 11, achieving a tight connection between the water-storing cartridge 30 and the outer casing 11 by tightening the threads.

[0200] The shape and size of the water-retaining cartridge 30 can be designed according to actual needs. For example, the water-retaining cartridge 30 can be designed as a cylinder, cuboid, or other shapes. The material of the water-retaining cartridge 30 can be transparent or semi-transparent food-grade silicone or polycarbonate (PC), which makes it easy for users to observe the remaining amount of moisturizing liquid, while also ensuring safety when in contact with skin.

[0201] As shown in Figures 13 to 15, in one embodiment of this application, one end of the outer shell 11 is recessed to form a mounting groove 112. The shape of the mounting groove 112 is adapted to the water storage bullet 30, and the water storage bullet 30 is detachably embedded in the mounting groove 112.

[0202] In this embodiment, the shape of the mounting groove 112 closely matches the shape of the water-storing bullet 30, ensuring that the water-storing bullet 30 can be tightly embedded and remain stable. For example, the shapes of the mounting groove 112 and the water-storing bullet 30 can be cylindrical, elliptical, or cuboid, etc., and the specific dimensions are determined according to actual needs.

[0203] The connection between the water-storage cartridge 30 and the mounting slot 112 can employ various design schemes. One implementation method is a snap-fit ​​connection, where the outer side of the water-storage cartridge 30 has an elastic snap-fit ​​structure, and the inner side of the mounting slot 112 has a corresponding slot. When the water-storage cartridge 30 is inserted into the mounting slot 112, the elastic snap-fit ​​automatically engages with the slot, achieving a secure connection. This connection method is simple to operate; the user only needs to press lightly to complete the installation or removal.

[0204] Another implementation method is to use a threaded connection. The outer side of the water-retaining cartridge 30 has external threads, and the inner side of the mounting groove 112 has internal threads. By tightening the threads, the water-retaining cartridge 30 and the outer casing 11 can be tightly connected. The advantages of the threaded connection are that the connection is firm and the sealing performance is good, making it particularly suitable for occasions where the water-retaining cartridge 30 needs to be frequently replaced.

[0205] The installation slot 112 design makes the installation and removal of the water storage cartridge 30 more convenient. Users can quickly replace the water storage cartridge 30 without complicated operations, significantly improving the ease of use of the equipment. At the same time, the tight fit design between the installation slot 112 and the water storage cartridge 30 ensures the stability of the water storage cartridge 30 during use and avoids water leakage problems caused by loosening or displacement.

[0206] To further enhance the performance and user experience of the water replenishment device 1, the wall of the mounting groove 112 can be fitted with an anti-slip texture or rubber pad to increase the friction between the water reservoir 30 and the outer casing 11, preventing the water reservoir 30 from loosening due to vibration or external force. Simultaneously, the rubber pad also acts as a buffer, reducing wear on the water reservoir 30 during installation and disassembly.

[0207] As shown in Figure 13, in one embodiment of this application, when the water-storing bullet 30 is installed in the mounting groove 112, there is a smooth transition between the outer surface of the water-storing bullet 30 and the outer surface of the outer shell 11.

[0208] In this embodiment, the mounting groove 112 and the nozzle 12 are both located at the same end of the outer casing 11, and the mounting groove 112 and the nozzle 12 are positioned opposite each other on both sides of the outer casing 11. The mounting groove 112 is located at a side corner of the outer casing 11. The outer casing 11 has rounded chamfers on all four sides, allowing the water-retaining bullet 30 to conform to the shape of the mounting groove 112. When the water-retaining bullet 30 is installed in the mounting groove 112, the surface of the water-retaining bullet 30 smoothly transitions to the surface of the outer casing 11. Furthermore, the surface of the water-retaining bullet 30 exposed on the outer side of the outer casing 11 is also a rounded surface. This design makes the overall appearance of the water-replenishing device 1 simpler and more aesthetically pleasing, enhancing the product's perceived quality. Simultaneously, this design also enhances user comfort during use and carrying, avoiding inconvenience caused by the water-retaining bullet 30 protruding or recessed. For example, when holding the water-replenishing device 1, the user will not feel a noticeable gap between the water-retaining bullet 30 and the outer casing 11, thus improving grip comfort.

[0209] As shown in Figures 14 and 15, in one embodiment of this application, a guide block 113 protrudes from the side wall of the mounting groove 112, and a guide groove 31 is provided on one side of the water storage bullet 30. The guide block 113 slides in the guide groove 31 and guides the water storage bullet 30 to be embedded in the mounting groove 112.

[0210] In this embodiment, a guide block 113 protrudes from the side wall of the mounting groove 112, and a guide groove 31 adapted to the guide block 113 is formed on one side of the water-storing bullet 30. The guide block 113 and the guide groove 31 are designed to guide the water-storing bullet 30 to slide along a predetermined trajectory during installation, ensuring that the water-storing bullet 30 can be accurately and smoothly embedded into the mounting groove 112. The guide block 113 can be trapezoidal, semi-circular, elongated, or other shapes suitable for sliding to reduce friction during installation and provide stable guidance. The depth and width of the guide groove 31 are adjusted according to the size of the guide block 113 to ensure that the two can fit tightly together. This design not only improves the convenience of installation but also reduces the risk of damage to the water-storing bullet 30 due to improper installation.

[0211] In one embodiment of this application, guide blocks 113 are provided on both sides of the mounting groove 112, and guide grooves 31 are also provided on both sides of the water storage bullet 30. Each guide block 113 is slidably disposed in a guide groove 31, which not only improves the convenience of installing the water storage bullet 30, but also extends along the direction in which the water storage bullet 30 is inserted into the mounting groove 112. Therefore, the guide blocks 113 and guide grooves 31 also play a limiting role for the water storage bullet 30 along the direction perpendicular to the insertion direction, thereby improving the stability of the water storage bullet 30.

[0212] Referring to Figures 15 to 18, in one embodiment of this application, the water replenishment device 1 further includes an unlocking component 40. The unlocking component 40 has a fixing part, and a mating part is provided on one side of the water storage bullet 30. The water storage bullet 30 is embedded in the mounting groove 112. The fixing part and the mating part are mutually limited and engaged. The unlocking component 40 is movably installed on the outer shell 11. Moving the unlocking component 40 causes the fixing part and the mating part to separate, and the water storage bullet 30 is removed from the outer shell 11.

[0213] In this embodiment, the fixing part can be designed as a plug 44 or a hook, while the mating part is a corresponding slot 32 or groove. For example, the fixing part is an elastic plug 44, one end of which is connected to the unlocking component 40, and the other end is inserted into the slot 32 on the water-retaining bullet 30. When the water-retaining bullet 30 is installed in place, the elastic plug 44 is engaged in the slot 32 to achieve limiting and fixing; when it is necessary to remove the water-retaining bullet 30, by moving the unlocking component 40, the elastic plug 44 is pulled out of the slot 32, and the water-retaining bullet 30 can be easily removed.

[0214] The unlocking component 40 can be designed as a sliding button or a rotating button, installed on the side or top of the housing 11. Users can control the movement of the unlocking component 40 through simple sliding or rotating operations, thereby dismantling the water-filled bullet 30.

[0215] The design of the unlocking component 40 makes the disassembly of the water-retaining bullet 30 simpler and faster. Users do not need tools or complicated procedures; they can disassemble the water-retaining bullet 30 simply by moving the unlocking component 40. This design significantly improves user convenience and reduces the risk of damage to the water-retaining bullet 30 due to improper disassembly.

[0216] Referring to Figure 18, in one embodiment of this application, the fixing part is a plug 44 and the mating part is a slot 32. The plug 44 is engaged in the slot 32 so that the water storage bullet 30 and the outer shell 11 can be detachably connected.

[0217] In this embodiment, the fixing part of the unlocking component 40 is designed as a plug 44. A slot 32 adapted to the plug 44 is provided on one side of the water storage bullet 30. The direction in which the plug 44 is inserted into the slot 32 is perpendicular to the direction in which the water storage bullet 30 is inserted into the mounting groove 112. Therefore, when the plug 44 is inserted into the slot 32, the plug 44 forms a limit on the water storage bullet 30 along the moving direction of the water storage bullet 30. Combined with the limit of the guide block 113 and the guide groove 31, the water storage bullet 30 can be stably kept in the mounting groove 112.

[0218] The end of the insert 44 is chamfered. This chamfer design allows the insert 44 to be inserted into the slot 32 more smoothly, thus achieving a stable connection between the water-retaining bullet 30 and the outer casing 11. The angle of the chamfer can be adjusted according to actual needs, generally designed as 45° or 30°, to ensure that the insert 44 can slide smoothly into the slot 32. At the same time, the inner wall of the slot 32 can be designed as an inclined slope or a curved surface so that the insert 44 can automatically align and smoothly enter the slot 32 during insertion.

[0219] Referring to Figures 16 and 18, in one embodiment of this application, the unlocking component 40 includes an unlocking key 41, a connecting block 43, and an elastic member 42. A limiting groove is provided in the mounting cavity 111, and the elastic member 42 is movably disposed in the limiting groove. One end of the connecting block 43 elastically abuts against the elastic member 42, and the other end is provided with an insert 44. One end of the unlocking key 41 is connected to the connecting block 43, and the other end is exposed on the outer surface of the housing 11. Moving the unlocking key 41 causes the connecting block 43 to compress the elastic member 42, and causes the insert 44 to separate from the slot 32.

[0220] In this embodiment, the unlock button 41 can be designed as a sliding button or a press button, installed on the side or top of the housing 11 for easy user operation. The connecting block 43 is used to transmit the action of the unlock button 41 to the insertion block 44, while the elastic element 42 provides the necessary elastic restoring force to ensure that the insertion block 44 can automatically reset after unlocking, and at the same time ensure that the insertion block 44 can be stably inserted into the slot 32 when locked. The elastic element 42 can be a spring or other elastic material, such as rubber or elastic plastic.

[0221] The limiting groove is designed to restrict the range of movement of the elastic element 42, ensuring its stability during compression and extension. The length and width of the limiting groove can be adjusted according to the dimensions of the elastic element 42 to ensure that the elastic element 42 can move smoothly within it.

[0222] The connection between the unlock button 41 and the connecting block 43 can be mechanically fixed, such as by screws, clips, or plugs. The other end of the connecting block 43 has a plug 44, the shape and size of which are adapted to the slot 32 on the water-storing bullet 30. When the unlock button 41 is moved, the connecting block 43 moves accordingly, compressing the elastic element 42, and simultaneously pulling the plug 44 out of the slot 32, completing the unlocking action.

[0223] In one embodiment of this application, as shown in FIG6, the end of the unlock button 41 facing the connecting block 43 has a chamfered surface. The chamfered surface is an inclined surface or a curved surface. By setting the chamfered surface, the cross-sectional dimension of the unlock button 41 gradually decreases in the direction toward the connecting block 43. The connecting block 43 has an inclined surface or curved surface that matches the chamfered surface. The two fit together. When the unlock button 41 is pressed, the chamfered surface drives the connecting block to move in the direction toward the compression spring, and at the same time, the insert 44 is pulled out from the slot 32. In addition, a limiting hole is also provided on the connecting block 43. A limiting block protrudes from the end face of the unlock button 41. The limiting block is at least partially embedded in the limiting hole. The limiting hole extends in the direction of pressing the unlock button 41, so that the connecting block 43 limits the unlock button 41 through the limiting hole, thereby improving the stability of the unlock button 41 when it is pressed and moved.

[0224] Referring to Figures 15 to 17, in one embodiment of this application, the water replenishment device 1 further includes a connecting pipe 60, which is disposed in the mounting cavity 111. The two ends of the connecting pipe 60 are respectively provided with a water inlet connector 61 and a water outlet connector 62. The water inlet connector 61 is connected to the water storage cavity 33, and the water outlet connector 62 is connected to the water circuit connector 122.

[0225] In this embodiment, the connecting tube 60 can be made of flexible or rigid materials, such as medical-grade silicone tubes or polycarbonate (PC) tubes, to ensure its safety and durability during use.

[0226] The inlet connector 61 and outlet connector 62 are designed to ensure a tight connection between the connecting pipe 60 and the water reservoir 30 and nozzle 12. The inlet connector 61 can be designed as a quick-connect interface, allowing for easy connection and disconnection when the user replaces the water reservoir 30. The outlet connector 62 connects to the water connector 122 of the nozzle 12 via a plug or through the air pipe 50, ensuring no leakage during use.

[0227] In one embodiment of this application, the connection between the water inlet connector 61 and the water storage chamber 33 of the water storage bullet 30 can be designed as a sealed structure, such as using an O-ring or rubber gasket, to prevent water leakage. A similar sealing design can also be used at the connection between the water outlet connector 62 and the water passage connector 122 of the nozzle 12 to ensure stable water flow transmission under high pressure.

[0228] By introducing the connecting pipe 60, the internal fluid transmission of the water supply device 1 becomes more efficient and stable. The design of the connecting pipe 60 not only simplifies the internal structure and reduces the complexity of the piping, but also facilitates the connection between the water storage cartridge 30 and the nozzle 12. When replacing the water storage cartridge 30, the user can simply plug and unplug the connecting pipe 60 to complete the connection and disconnection operations, significantly improving the convenience of use.

[0229] Referring to Figures 16 and 17, in one embodiment of this application, the connecting pipe 60 is provided with a water outlet connector 62 at one end and an air valve connector 63 at the other end. The water replenishment device 1 also includes a pneumatic element, which is located in the mounting cavity 111 and has one end connected to the outside of the outer shell 11 and the other end connected to the air valve connector 63. The pneumatic element provides air pressure and drives the replenishment liquid in the water storage cavity 33 to enter the water circuit connector 122 through the water outlet connector 62.

[0230] In this embodiment, the pneumatic component provides stable air pressure and drives the replenishing liquid in the water storage chamber 33 through the water outlet connector 62 into the water circuit connector 122, where it mixes with the airflow and is atomized and sprayed out at the nozzle 12. The pneumatic component can be a miniature air pump or a pneumatic valve, the specific choice depending on the size of the equipment and user requirements. The air valve connector 63 and the pneumatic component are connected by an air pipe 50. The surface of the outer casing 11 has air holes, and the pneumatic component is connected to the air holes through the air pipe 50 to achieve air pressure balance inside the pneumatic component.

[0231] The pneumatic components and air valve connector 63, in addition to driving the replenishing liquid in the water storage chamber 33 into the nozzle 12, can also realize the self-cleaning function of the water replenishment device 1. For example, when it is necessary to clean the fluid pipe inside the water replenishment device 1, the air pump 20 is turned on and the nozzle 12 is blocked by hand. At this time, the air pressure of the air pump 20 will be discharged through the air connector 121, the nozzle 12, the water connector 122, the water outlet connector 62, the connecting pipe 60, the air valve connector 63, the pneumatic components, and finally through the air holes opened on the surface of the outer shell 11, thereby realizing the self-cleaning of the water replenishment device 1.

[0232] To ensure the stability and reliability of pneumatic components, an internal filter can be installed to remove impurities and moisture from the air. Furthermore, the pneumatic components can be equipped with a pressure regulator, allowing users to adjust the air pressure as needed, thereby controlling the atomization effect of the makeup water.

[0233] By introducing pneumatic components and an air valve connector 63, the atomization effect of the water replenishment device 1 is significantly improved. The stable air pressure provided by the pneumatic components effectively propels the replenishing liquid through the connecting pipe 60 to the nozzle 12, where it mixes with the airflow and is then atomized and sprayed out. This design not only improves the transmission efficiency of the replenishing liquid but also enhances the stability and reliability of the equipment. Furthermore, the introduction of pneumatic components provides users with a more flexible operating experience. Users can control the atomization effect of the replenishing liquid by adjusting the air pressure according to different usage scenarios and personal preferences. This design is particularly suitable for occasions requiring different atomization intensities, significantly improving the user experience.

[0234] As shown in Figure 18, in one embodiment of this application, the water storage bullet 30 has a water outlet 34 at one end facing the mounting cavity 111, and the water replenishment device 1 also includes a sealing member 70. One end of the sealing member 70 is disposed in the water storage cavity 33, and the other end is elastically connected to the end of the water storage bullet 30.

[0235] When the water-storing bullet 30 is removed from the outer casing 11, the sealing element 70 blocks the water outlet 34; when the water-storing bullet 30 is installed on the outer casing 11, the water inlet connector 61 presses against and drives the sealing element 70 to move toward the inside of the water storage cavity 33 to open the water outlet 34.

[0236] In this embodiment, the seal 70 can be made of an elastic material, such as silicone or rubber, to ensure good elasticity and sealing performance during use. The shape of the seal 70 can be adjusted according to the size of the water outlet 34, for example, designed as a circle or an ellipse, to ensure a tight fit with the water outlet 34. The diameter of the water outlet 34 can be adjusted according to the capacity of the water reservoir 30 and the flow rate requirement of the nozzle 12, for example, designed as 2mm to 5mm, to ensure smooth flow of the replenishing liquid. The elastic connection portion of the seal 70 can be designed as a small spring or an elastic rubber ring to provide the necessary elastic force, enabling the seal 70 to automatically seal the water outlet 34 when the water reservoir 30 is removed.

[0237] When the water reservoir 30 is installed on the housing 11, the water inlet connector 61 contacts the seal 70 and applies pressure. The design of the water inlet connector 61 should ensure that it can smoothly press against the seal 70, causing it to move towards the interior of the water reservoir 33, thereby opening the water outlet 34. The water inlet connector 61 can be cylindrical, with a diameter smaller than that of the water outlet 34, to ensure that after the seal 70 opens the water outlet 34, the replenishing fluid in the water reservoir 33 can flow smoothly into the connecting pipe 60. When the water reservoir 30 is removed from the housing 11, the elastic force generated by the elastic part of the seal 70 will push the seal 70 back to its original position, thereby sealing the water outlet 34 and preventing the replenishing fluid from leaking.

[0238] This design not only prevents leakage of the replenishing fluid during storage and transportation but also improves the sealing performance and service life of the water reservoir 30. The elastic design of the seal 70 ensures its reliability and stability during use, while providing users with a more convenient user experience. During the installation and removal of the water reservoir 30, the seal 70 can automatically adjust its position to ensure the opening and closing of the water outlet 34. This design is particularly suitable for applications requiring frequent replacement of the water reservoir 30, significantly enhancing the user experience.

[0239] Referring to Figures 19 to 22, this application proposes a water replenishment device, comprising:

[0240] The housing 104 is provided with a water nozzle 15 and a mounting groove 112. The water nozzle 15 is connected to an air pipe and a water pipe. The housing 104 is provided with an unlocking key 41.

[0241] An air pump is installed in the housing 104 and connected to the air pipeline to increase the water pressure at the spray nozzle 15.

[0242] Water storage bullet 30, which is detachably installed on the housing 104 and connected to the water pipeline, and the water storage bullet 30 is provided with a locking part;

[0243] Locking component 304, which is tractively connected to the unlocking key 41 and is disposed opposite to the locking part; and

[0244] An energy storage component is installed on the water storage bullet 30 and / or the housing 104. The water storage bullet 30 has a locked state and an ejected state. In the locked state, the locking component 304 cooperates with the locking part to lock the water storage bullet 30 in the mounting groove 112. In the ejected state, pressing the unlock button 41 causes the locking component 304 to disengage from the locking part, and the energy storage component pushes the water storage bullet 30 out of the mounting groove 112.

[0245] The water replenishment device in this application uses an air pump to pressurize the water flow from the nozzle 15 of the water-storage bullet 30, significantly increasing the water pressure at the nozzle 15 and resulting in a finer and more powerful atomized spray, thus improving the water replenishment effect and user experience. Furthermore, the water-storage bullet 30 can be firmly locked into the mounting groove 112 by the cooperation of the locking component 304 and the locking part, thereby improving the stability and reliability of the water-storage bullet 30. Simultaneously, when the user needs to clean the water-storage bullet 30, replenish water, or replace it with a different type, the user only needs to press the unlock button 41 to disengage the locking component 304 from the locking part. At this time, the energy storage component pushes the water-storage bullet 30 out of the mounting groove 112, allowing the user to remove the water-storage bullet 30 manually without having to pry it open, thus facilitating its removal and replacement. Furthermore, by installing sensors on the housing 104 and / or the water-retaining bullet 30, the sensors can identify whether the water-retaining bullet 30 is installed correctly. Simultaneously, there are various types of water-retaining bullets 30, each containing different liquids and corresponding to different functions. For example, there are different types of water-retaining bullets 30, such as moisturizing water-retaining bullets, lifting water-retaining bullets, soothing water-retaining bullets, and toning water-retaining bullets. The sensors can identify different types of water-retaining bullets 30, thereby controlling the air pump to spray the corresponding type of liquid to achieve the corresponding beauty effect. The sensors can be NFC, optical sensors, etc.

[0246] Specifically, the energy storage component includes a first magnetic element 414 and a second magnetic element 424. The first magnetic element 414 is mounted on the housing 104, and the second magnetic element 424 is mounted on the water-storing bullet 30. In the locked state, the first magnetic element 414 is positioned close to the outer periphery of the housing 104 relative to the second magnetic element 424. When switching from the locked state to the ejection state, the magnetic attraction between the first magnetic element 414 and the second magnetic element 424 drives the water-storing bullet 30 to eject from the mounting slot 112. The magnetic force between the first and second magnetic elements 424, respectively mounted on the housing 104 and the water-storing bullet 30, serves as the ejection power source. In the locked state, the first magnetic element 414 is positioned close to the outer periphery of the housing 104 relative to the second magnetic element 424, forming an energy storage state. When the lock is released, the magnetic attraction between the two elements instantly and reliably pushes the water-storing bullet 30 partially out of the mounting slot 112 in a predetermined direction. The design has significant advantages: First, its power output is smooth and there is no mechanical contact wear, resulting in a long lifespan and high reliability. Second, when the water-storing bullet 30 is ejected under the attraction of the first magnetic component 414 and the second magnetic component 424, it does not eject completely. Instead, it stops moving upwards when it reaches the same height as the first magnetic component 414 and the second magnetic component 424. At this point, the water-storing bullet 30 is locked in the mounting groove 112 by the magnetic attraction of the first magnetic component 414 and the second magnetic component 424. When the user needs to remove it, they only need to apply a certain force in a specific direction to remove the water-storing bullet 30 from the mounting groove 112. This prevents the water-storing bullet 30 from detaching from the mounting groove 112 during ejection, thus avoiding it falling and being damaged. This improves the stability and reliability of the water-storing bullet 30.

[0247] In other embodiments, the energy storage component may also be an elastic element 42. By providing the elastic element 42 on the housing 104 and / or the water storage bullet 30, the elastic element 42 is compressed between the housing 104 and the water storage bullet 30 when the water storage bullet 30 is in the locked state; when the water storage bullet 30 is in the popped state, pressing the unlock button 41 causes the locking component 304 to disengage from the locking part, and the water storage bullet 30 pops out of the mounting groove 112 at least partially under the action of the elastic element 42.

[0248] Referring to Figures 23 to 25, specifically, the locking assembly 304 includes an elastic element, a plug 44, and a push plate 334. The locking part is a snap-fit ​​groove 21. The plug 44 is elastically connected to the housing 104 via the elastic element. The unlocking key 41 is installed on the push plate 334. In the locked state, the plug 44 is snapped into the snap-fit ​​groove 21, so that the water-filled bullet 30 is locked in the mounting groove 112. When switching from the locked state to the pop-out state, pressing the unlocking key 41 causes the push plate 334 to push the plug 44, so that the plug 44 disengages from the snap-fit ​​groove 21. By employing a linkage mechanism in which the elastic element provides the restoring force, the plug 44 and the snap-fit ​​groove 21 perform the locking action, and the push plate 334 transmits the operation of the unlocking key 41, a highly efficient and reliable locking and unlocking system is constructed. In the locked state, the insert 44, under the action of the elastic element, engages with the locking groove 21 of the water-retaining cartridge 30, achieving a secure mechanical lock and ensuring that the water-retaining cartridge 30 will not loosen during use. When replacement is needed, the user presses the unlock button 41, driving the push plate 334 to move. The push plate 334 acts directly on the insert 44, forcing it to overcome the force of the elastic element and disengage from the locking groove 21, thus instantly releasing the lock. This design precisely and directly converts the linear pressing action of the unlock button 41 into the lateral unlocking movement of the insert 44, resulting in a short transmission path, rapid response, and a clear and powerful unlocking action. Simultaneously, the mechanical latch structure provides reliable locking and is cost-effective.

[0249] Furthermore, the elastic element includes an elastic element 42, with its two ends fixed to the housing 104 and the insert 44, respectively. The elastic element 42 connects the housing 104 and the insert 44, providing the insert 44 with a continuous, stable, and directional elastic reset force. This ensures that, in the locked state, the insert 44 remains firmly engaged in the locking groove 21 of the water reservoir 30 with sufficient pressure, effectively preventing accidental unlocking due to vibration or slight external force, ensuring a stable and reliable locking state. After the unlocking action is completed, once the user releases the unlock button 41, the elastic element 42 immediately drives the insert 44 to accurately and quickly reset to the position ready for the next locking, ensuring the cyclic reliability of the locking assembly 304. Simultaneously, the elastic element 42 is stable and reliable, has low cost, and a long service life, thereby reducing the production cost of the water replenishment device and increasing its service life.

[0250] Furthermore, the insert 44 is provided with a first pushing surface, and the pushing plate 334 is provided with a second pushing surface 331. Both the first and second pushing surfaces 331 are inclined and fit together. When the unlock button 41 is pressed, the pushing plate 334 pushes the insert 44 away from the latching groove 21 through the cooperation of the second pushing surface 331 and the first pushing surface. By limiting the transmission method between the insert 44 and the pushing plate 334 to use inclined surfaces, the force transmission efficiency and operating feel are optimized. Specifically, the first and second pushing surfaces 331 are both inclined and fit together. When the user presses the unlock button 41 vertically, the pushing plate 334 moves vertically, and its second pushing surface 331 slides into contact with the first pushing surface of the insert 44. Because the contact surface is inclined, the vertical pressing force is cleverly decomposed into a horizontal component force. This component force directly pushes the insert 44 to move laterally, thus unlocking the device. This inclined transmission mechanism has a labor-saving effect, allowing users to overcome the large locking force of the insert 44 with a smaller pressing force, thereby obtaining a light and smooth button feel. At the same time, the inclined contact makes the force transmission smooth and gradual, avoiding sudden impacts, reducing wear on parts, and improving the service life of the mechanism and the comfort of operation.

[0251] In one embodiment, the push plate 334 is provided with a limiting plate 332, and the housing 104 is provided with a first limiting groove 13. The limiting plate 332 is located within the first limiting groove 13, and the extending directions of the limiting plate 332 and the first limiting groove 13 are consistent with the pressing direction of the unlocking key 41. By setting the limiting plate 332 on the push plate 334 to cooperate with the corresponding first limiting groove 13 in the housing 104, and its extending direction is consistent with the pressing direction of the unlocking key 41, a strict linear guiding constraint is provided for the movement of the push plate 334. This ensures that the insert 44 can only move precisely in a preset horizontal direction, that is, perpendicular to the pressing direction of the unlocking key 41, during elastic reset and unlocking by the push plate 334, without deflection, warping, or jamming, thereby improving the stability and reliability of the water replenishment device.

[0252] Preferably, the outward-facing side of the insert 44 is provided with a guide slope 322 to facilitate the insertion of the insert 44 into the locking groove 21. The guide slope 322 facilitates the insertion of the insert 44 into the locking groove 21, thereby improving the installation efficiency of the water storage bomb 30.

[0253] In one embodiment, the water replenishment device further includes a flexible waterproof block 504, which is arranged in a ring shape. The inner peripheral wall of the flexible waterproof block 504 is sealed to the push plate 334, and the outer peripheral wall of the flexible waterproof block 504 is sealed to the housing 104. This reduces the intrusion of liquids (such as sweat, cosmetics, or accidental splashes) and dust and impurities from the external environment into the housing 104 through the gap around the unlocking key 41, protecting the internal precision air pump, circuitry (if any), and locking mechanism from contamination and corrosion, and improving the environmental adaptability and service life of the water replenishment device.

[0254] In one embodiment, the housing 104 is provided with a first guide portion, and the water-storing bullet 30 is provided with a second guide portion. The water-storing bullet 30, through the cooperation of the first and second guide portions, restricts its trajectory within the mounting groove 112. On one hand, during installation of the water-storing bullet 30, the first and second guide portions provide a foolproof positioning function, facilitating installation and improving efficiency. Simultaneously, during the magnetic ejection of the water-storing bullet 30, this cooperative structure ensures that it rises smoothly along the straight path defined by the first and second guide portions, without rotation, swaying, or jamming. This ensures that the water spray interface of the water-storing bullet 30 can smoothly and straighten from the water interface within the housing 104 during ejection, reducing unnecessary wear on the sealing ring and preventing liquid leakage due to misalignment. Furthermore, the final ejection position and posture of the water-storing bullet 30 are stable and predictable, allowing the user to easily retrieve it at the same angle each time.

[0255] Specifically, the first guiding part is a guide block 124, and the second guiding part is a second limiting groove 224, with the guide block 124 confined within the second limiting groove 224. The guide block 124 and the second limiting groove 224 have simple structures, which facilitates the production and manufacturing of the water-storing bomb 30 and the shell 104, and their performance is stable and reliable, thereby improving the stability and reliability of the water-storing bomb 30.

[0256] The above description is merely an exemplary embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the technical concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
