[0015] In one embodiment of this utility model, the unlocking component includes an unlocking key, a connecting block, and an elastic element. A limiting groove is provided in the mounting cavity, and the elastic element is movably disposed in the limiting groove. One end of the connecting block elastically abuts against the elastic element, and the other end is provided with the insertion block. One end of the unlocking key is connected to the connecting block, and the other end is exposed on the outer surface of the housing. Moving the unlocking key causes the connecting block to compress the elastic element and causes the insertion block to separate from the slot.

[0016] In one embodiment of this utility model, the water replenishment rod further includes a connecting pipe, which is disposed in the mounting cavity. The two ends of the connecting pipe are respectively provided with a water inlet connector and a water outlet connector. The water inlet connector is connected to the water storage cavity, and the water outlet connector is connected to the water circuit connector.

[0017] In one embodiment of this utility model, the end of the connecting pipe with the water outlet connector is also provided with an air valve connector, and the water replenishment rod also includes a pneumatic element. The pneumatic element is located in the mounting cavity, with one end connected to the outside of the outer shell and the other end connected to the air valve connector.

[0034] This invention proposes a water replenishment stick 1, aiming to solve the problems of low efficiency and easy leakage when replacing the replenishing fluid in existing water replenishment sticks 1. Traditional water replenishment sticks 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 during the filling process, affecting the user experience. To overcome these shortcomings, this invention innovatively improves the water replenishment stick 1.

[0035] Combination Figures 1 to 4 As shown, in one embodiment of this utility model, the water replenishing stick 1 includes a housing assembly 10, an air pump 20, and a water storage bullet 30; the housing assembly 10 includes a shell 11 and a nozzle 12, the shell 11 has an installation cavity 111 inside, the nozzle 12 is installed in the shell 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; the water storage bullet 30 has a water storage chamber 33 inside, the water storage chamber 33 is filled with water replenishing liquid, the water storage bullet 30 is detachably installed in the shell 11, when the water storage bullet 30 is installed in the shell 11, the water storage chamber 33 communicates with the water connector 122, when the water storage bullet 30 is removed from the shell 11, the water storage chamber 33 is in a self-sealing state.

[0036] The core design feature of this application lies in the detachability and self-sealing characteristics of the water reservoir 30. When the replenishing fluid inside the water reservoir 30 is depleted, the user does not need to refill it through the inlet; instead, they can directly remove the water reservoir 30 from the outer casing 11 and replace it with a new one. Since the unused water reservoir 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 on the water pump 1 but also avoids the problem of replenishing fluid leakage, significantly enhancing the user experience.

[0037] Specifically, the outer shell 11 can 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 can be designed as quick-plug interfaces, facilitating quick replacement of the water reservoir 30 and maintenance of the device. Furthermore, the air pump 20 can 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 to achieve hydration. The outlet of the nozzle 12 can be designed with fine nozzle holes to achieve better atomization, allowing the hydrating liquid to be sprayed evenly onto the skin surface.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] Combination Figures 1 to 3 As shown, in one embodiment of the present invention, one end of the outer shell 11 is recessed to form an installation groove 112. The shape of the installation groove 112 is adapted to the water storage bullet 30, and the water storage bullet 30 is detachably embedded in the installation groove 112.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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 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.

[0046] To further improve the performance and user experience of the water replenishment stick 1, the wall of the mounting groove 112 can be provided with a layer of 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. At the same time, the rubber pad can also act as a buffer, reducing wear on the water reservoir 30 during installation and removal.

[0047] Combination Figure 1 As shown, in one embodiment of the present invention, when the water storage bullet 30 is installed in the mounting groove 112, there is a smooth transition between the outer surface of the water storage bullet 30 and the outer surface of the outer shell 11.

[0048] In this embodiment, the mounting groove 112 and the nozzle 12 are both located at the same end of the outer shell 11, and the mounting groove 112 and the nozzle 12 are positioned opposite each other on both sides of the outer shell 11. The mounting groove 112 is located at a side corner of the outer shell 11. The outer shell 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 shell 11. Furthermore, the surface of the water-retaining bullet 30 exposed on the outer side of the outer shell 11 is also a rounded surface. This design makes the overall appearance of the water-retaining stick 1 more concise and 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-retaining stick 1, the user will not feel a noticeable gap between the water-retaining bullet 30 and the outer shell 11, thus improving grip comfort.

[0049] Combination Figure 2 and Figure 3 As shown, in one embodiment of the present invention, 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.

[0050] 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.

[0051] Furthermore, 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 slides 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 limit the water storage bullet 30 along the direction perpendicular to the insertion direction, thus improving the stability of the water storage bullet 30.

[0052] Combination Figures 3 to 6 As shown, in one embodiment of this utility model, the water replenishing stick 1 further includes an unlocking component 40. The unlocking component 40 is provided with a fixing part, and a matching 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 matching part are mutually limited and matched. The unlocking component 40 is movably installed on the outer shell 11. Moving the unlocking component 40 causes the fixing part and the matching part to separate, and the water storage bullet 30 is removed from the outer shell 11.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] Combination Figure 6 As shown, in one embodiment of this utility model, the fixing part is a plug 44 and the mating part is a slot 32. The plug 44 is inserted into the slot 32 so that the water storage bullet 30 and the outer shell 11 can be detachably connected.

[0057] 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.

[0058] 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.

[0059] Combination Figure 4 and Figure 6 As shown, in one embodiment of this utility model, 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 block 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 block 44 to separate from the slot 32.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] Furthermore, as shown in Figure 6, the end of the unlock button 41 facing the connecting block 43 has a chamfered surface. The chamfered surface is either 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 towards 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 towards the compression spring, while the insert 44 is pulled out of 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, improving the stability of the unlock button 41 when it is pressed and moved.

[0064] Combination Figures 3 to 5 As shown, in one embodiment of this utility model, the water replenishment rod 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.

[0065] 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.

[0066] 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.

[0067] Furthermore, 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 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 under high pressure.

[0068] By introducing the connecting pipe 60, the internal fluid transmission of the water supply rod 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 pipeline, but also facilitates the connection between the water storage bullet 30 and the nozzle 12. When replacing the water storage bullet 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.

[0069] Combination Figure 4 and Figure 5 As shown, in one embodiment of this utility model, 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 rod 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.

[0070] 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.

[0071] 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 achieve the self-cleaning function of the water replenishing rod 1. For example, when it is necessary to clean the fluid pipe inside the water replenishing rod 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 achieving the self-cleaning of the water replenishing rod 1.

[0072] 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.

[0073] By introducing pneumatic components and an air valve connector 63, the atomization effect of the water replenishment rod 1 is significantly improved. The stable air pressure provided by the pneumatic components effectively propels the replenishment 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 replenishment 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 replenishment 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.

[0074] Combination Figure 6 As shown, in one embodiment of the present invention, the water storage bullet 30 has a water outlet 34 at one end facing the mounting cavity 111, and the water replenishment rod 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.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
