[0002] 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, moisturizing devices, as a convenient and portable skincare product, have the functions of moisturizing, maintaining the skin's water-oil balance, reducing wrinkles, and preparing the skin before makeup, and are therefore favored by many beauty-conscious women.

[0003] 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. Utility Model Content

[0004] The main purpose of this invention is to propose a small portable hydration device, which aims to solve the problem that the air pump of existing hydration devices affects the layout of various components and makes it difficult to achieve the requirements of miniaturization and compactness.

[0005] To achieve the above objectives, the present invention proposes a small portable hydration device, which includes:

[0006] A housing assembly, the housing assembly including a housing and a nozzle, the housing having a first mounting cavity formed inside the housing, the nozzle being mounted on the housing and communicating with the first mounting cavity, the nozzle including a body and an air connector and a water connector disposed at one end of the body facing the first mounting cavity and communicating with the body;

[0007] A water-storing bomb, which is mounted on the outer casing and connected to the water passage connector; and

[0008] At least two air pumps are installed in the first mounting cavity and connected to the air connection connector;

[0009] The airflow generated by the air pump mixes with the liquid provided by the water storage bomb and is then atomized and sprayed out through the nozzle.

[0010] In one embodiment of this utility model, two air pumps are provided, which are spaced apart along a direction perpendicular to the axial direction of the air pumps and located at the end of the housing away from the nozzle and the water storage bullet.

[0011] In one embodiment of this utility model, the housing assembly further includes multiple air pipes, the water storage bomb is connected to the water circuit connector through one of the air pipes, and the two air pumps are connected to the air circuit connector through the air pipes.

[0012] In one embodiment of this utility model, the air outlet of one air pump is connected to the air inlet of another air pump through one air pipe, and the air outlet of the other air pump is connected to the air circuit connector through another air pipe.

[0013] In one embodiment of this utility model, the small portable hydration device further includes a three-way tube, the air outlets of the two air pumps are respectively connected to two channels of the three-way tube, and the other channel of the three-way tube is connected to the air circuit connector through the air pipe.

[0014] In one embodiment of the present invention, the outer casing forms two first mounting cavities, and each air pump is embedded in one of the first mounting cavities.

[0015] In one embodiment of the present invention, the outer shell includes a front shell plate and a rear shell plate, the front shell plate and the rear shell plate are detachably connected, and the front shell plate and the rear shell plate enclose two first mounting cavities.

[0016] In one embodiment of this utility model, one end of the air pump connected to the air circuit connector is the first end, and the other end of the air pump is the second end. The cross-sectional dimension of the first end is larger than that of the second end. The cavity wall of the first mounting cavity is provided with a limiting step. The second end is inserted into the first mounting cavity, and the first end abuts against the limiting step.

[0017] In one embodiment of the present invention, the cavity wall of the first mounting cavity is provided with a plurality of limiting ribs, and the air pump is embedded in the first mounting cavity and its periphery is limited and abutted against the plurality of limiting ribs.

[0018] In one embodiment of the present invention, a second mounting cavity is further formed inside the outer shell. The second mounting cavity and the first mounting cavity are arranged at intervals along the axial direction of the air pump. The air connector and the water connector are located in the second mounting cavity. The small portable hydration device also includes a battery, which is installed in the second mounting cavity.

[0019] This utility model proposes a small portable hydration device comprising a housing assembly, a water storage cartridge, and at least two air pumps. The housing assembly includes an outer shell and a nozzle. A first mounting cavity is formed inside the outer shell, and the nozzle is mounted on one side of the outer shell. The end of the nozzle facing inwards from the outer shell has an air inlet and a water inlet. The water storage cartridge is mounted on the outer shell and connected to the water inlet.

[0032] This utility model proposes a small portable hydration device 1.

[0033] Combination Figure 1 , Figure 2 as well as Figure 4 and Figure 5As shown, in one embodiment of this utility model, the small portable hydration device 1 includes a housing assembly 10, a water storage cartridge 20, and at least two air pumps 30; the housing assembly 10 includes a shell 11 and a nozzle 12, a first mounting cavity 113 is formed inside the shell 11, the nozzle 12 is installed on the shell 11 and communicates with the first mounting cavity 113, the nozzle 12 includes a body and an air connector 122 and a water connector 121 located at one end of the body facing the first mounting cavity 113 and communicating with the body; the water storage cartridge 20 is installed on the shell 11 and communicates with the water connector 121; at least two air pumps 30 are installed in the first mounting cavity 113 and communicate with the air connector 122; wherein the airflow generated by the air pumps 30 mixes with the liquid provided by the water storage cartridge 20 and is atomized by the nozzle 12 before being sprayed out.

[0034] In this embodiment, the small portable hydration device 1 is designed as a long, rectangular shape for easy handheld operation. The edges and corners of the long, rectangular portable hydration 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 a smooth surface that is easy to clean.

[0035] The water flow from the water reservoir 20 and the airflow from the air pump 30 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 users to easily and naturally aim it at their face or other areas requiring care. The water reservoir 20 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.

[0036] The water storage bomb and the water connector 121 can be connected by plugging or by air pipe; the same applies to the air pump and the air connector 122.

[0037] Because this application incorporates at least two air pumps 30, the required air pressure for a single air pump 30 is lower. Consequently, the volume occupied by a single air pump 30 in the first mounting cavity 113 is smaller. This facilitates the rational arrangement of the air pumps 30 according to the shape of the internal components and the available space of the small portable hydration 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 30 allow for series or parallel connection between them. Even if one air pump 30 fails, the other air pump 30 can continue to operate, ensuring the stability and reliability of the device.

[0038] Combination Figure 2 and Figure 4As shown, in one embodiment of this utility model, there are two air pumps 30, which are spaced apart along a direction perpendicular to the axial direction of the air pumps 30 and located at the end of the housing 11 away from the nozzle 12 and the water storage bullet 30.

[0039] In this embodiment, the two air pumps 30 are placed parallel to each other on the same horizontal line, maintaining an appropriate distance. This layout ensures that each air pump 30 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 30.

[0040] The two air pumps 30 can be configured with different specifications or with the same specifications. For example, in this embodiment... Figure 4 As shown, two air pumps 30 of the same specifications and dimensions are selected and placed at the bottom of the small portable hydration device 1, that is, at the end of the outer shell 11 away from the nozzle 12 and the water reservoir 30. Since the air pumps 30 are relatively heavy, this design improves the grip and stability of the device during use. Furthermore, because the two air pumps 30 have similar or identical weights, arranging them at intervals perpendicular to their axial direction allows for a symmetrical arrangement within the first mounting cavity 113, further enhancing structural stability and grip. This symmetrical design also improves the utilization of internal space within the outer shell 11, facilitating structural layout.

[0041] In addition, when the required air pressure for atomization is low, the small portable hydration device 1 can be configured to either output lower power from both air pumps 30, or to operate only one air pump 30. For example, one air pump 30 can be used as the main drive source to generate the basic airflow, while the other acts as an auxiliary pressurization unit to further pressurize the airflow, ultimately creating a stable high-pressure airflow to atomize the liquid. This method not only provides a wider 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 30 operates; while in high-power mode, both air pumps 30 work together to achieve a stronger spray effect. Alternatively, both air pumps 30 can be set to output power simultaneously in both low and high-power modes.

[0042] Each air pump 30 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.

[0043] Furthermore, a layer of sound-insulating material was wrapped around the air pump 30, which effectively reduced the noise generated during operation and improved the user experience.

[0044] Combination Figures 2 to 4 As shown, in one embodiment of the present invention, the housing assembly 10 further includes a plurality of air pipes 13, the water storage bomb 20 is connected to the water connector 121 through an air pipe 13, and the two air pumps 30 are connected to the air connector 122 through the air pipes 13.

[0045] In this embodiment, by setting up an air pipe 13 and connecting the water reservoir 20 to the water connector 121, and the air pump 30 to the air connector 122 via the air pipe 13, 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 13 uses a quick-plug interface with the air pump 30, water reservoir 20, 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.

[0046] Combination Figure 2 and Figure 4 As shown, in one embodiment of this utility model, the air outlet 34 of one air pump 30 is connected to the air inlet 33 of another air pump 30 through an air pipe 13, and the air outlet 34 of the other air pump 30 is connected to the air connector 122 through another air pipe 13.

[0047] In this embodiment, the two air pumps 30 are connected in series. Specifically, the first air pump 30 initially compresses the air, and then the compressed gas is transmitted to the second air pump 30 for secondary pressurization through the air pipe 13. Finally, the high-pressure airflow after double compression flows out from the outlet 34 of the second air pump 30 and directly reaches the nozzle 12 through the air pipe 13, forming a powerful atomizing force. This design allows the first air pump 30 to operate independently during the startup phase, and the second air pump 30 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 30 not only facilitates multi-level adjustment functions but also reduces the workload of a single air pump 30, extending the service life of the equipment.

[0048] Combination Figure 3 As shown, in one embodiment of this utility model, the small portable hydration device 1 also includes a three-way pipe 50, the air outlets 34 of the two air pumps 30 are respectively connected to the two channels of the three-way pipe 50, and the other channel of the three-way pipe 50 is connected to the air connector 122 through the air pipe 13.

[0049] In this embodiment, the two air pumps 30 are connected in parallel via a three-way pipe 50. The three-way pipe 50 can be Y-shaped or T-shaped. Its inner surface 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 50 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 30 converges at the three-way pipe 50 after entering, forming a higher and more uniform airflow.

[0050] This design, which utilizes a three-way tube 50 to connect two air pumps 30 in parallel, solves the problem of traditional small portable hydration devices 1 struggling to coordinate the synchronous operation of multiple air pumps 30, achieving effective integration and optimized distribution of airflow. Users can easily switch between different settings according to their actual needs, obtaining a more stable and efficient skincare experience.

[0051] Combination Figure 4 and Figure 5 As shown, in one embodiment of the present invention, the outer shell 11 forms two first mounting cavities 113, and each air pump 30 is embedded in a first mounting cavity 113.

[0052] In this embodiment, to improve the ease of installation of the two air pumps 30, two first mounting cavities 113 are provided inside the housing 11 of the small portable hydration device 1. Each of these two first mounting cavities 113 provides a dedicated mounting position for one air pump 30, thus avoiding potential interference between the two air pumps 30. When the two air pumps 30 have different models or sizes, different shapes and sizes of first mounting cavities 113 can be provided according to different models of air pumps 30 to achieve compatibility between the air pumps 30 and the first mounting cavities 113. In addition, the two separate first mounting cavities 113 help to disperse heat and prevent excessively high local temperatures from affecting the performance or safety of the device.

[0053] Combination Figure 1 and Figure 5 As shown, in one embodiment of the present invention, the outer shell 11 includes a front shell plate 111 and a rear shell plate 112, which are detachably connected. The front shell plate 111 and the rear shell plate 112 enclose each other to form two first mounting cavities 113.

[0054] In this embodiment, the front shell 111 and the rear shell 112 are detachably connected by means of snap-fit, threaded connection or plug-in. By setting the outer shell 11 so that the front shell 111 and the rear shell 112 are detachably connected, when it is necessary to repair or replace the internal components of the small portable hydration device 1, the user can easily open the outer shell 11 with simple operation without the need for professional tools.

[0055] Furthermore, the front shell 111 and rear shell 112 fit together tightly, forming two independent first mounting cavities 113, with each air pump 30 embedded in one of these cavities. This layout not only provides dedicated installation space for the air pumps 30, avoiding mutual interference, but also improves the ease of installation for both air pumps 30. During installation, the air pump 30 is simply inserted into either the front shell 111 or the rear shell 112, and then the two shells are fastened together. To enhance waterproofing, the joints between the front shell 111 and the rear shell 112 are sealed, including critical areas such as the air pipe 13 connection port and the power cord inlet, preventing liquid ingress and damage to internal electronic components.

[0056] In addition, control panels can be integrated on the front shell 111 and the rear shell 112, 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.

[0057] Combination Figure 4 and Figure 5 As shown, in one embodiment of the present invention, one end of the air pump 30 connected to the air circuit connector 122 is the first end 31, and the other end of the air pump 30 is the second end 32. The cross-sectional dimension of the first end 31 is larger than that of the second end 32. The cavity wall of the first mounting cavity 113 is provided with a limiting step 116. The second end 32 is inserted into the first mounting cavity 113, and the first end 31 abuts against the limiting step 116.

[0058] In this embodiment, one end (first end 31) of the air pump 30 is designed with a larger cross-sectional size, while the other end (second end 32) is relatively smaller. This stepped design can provide clear directional guidance during installation and prevent reverse installation or misoperation.

[0059] The first mounting cavity 113 has a dedicated limiting step 116 on its cavity wall, or the first mounting cavity 113 can also be set in a stepped shape to adapt the shape of the first mounting cavity 113 to the air pump 30. When the air pump 30 is inserted into the first mounting cavity 113, the first end 31 abuts against the limiting step 116, and the second end 32 abuts against the bottom wall of the first mounting cavity 113, together providing physical support for the air pump 30. The presence of the limiting step 116 also allows the air pump 30 to maintain a stable position when subjected to external impact or vibration, reducing the risk of loosening or displacement.

[0060] Combination Figure 5 As shown, in one embodiment of the present invention, the cavity wall of the first mounting cavity 113 is provided with a plurality of limiting ribs 117, and the air pump 30 is embedded in the first mounting cavity 113 and is limited and abutted against the plurality of limiting ribs 117 on its periphery.

[0061] In this embodiment, to ensure that the air pump 30 can be stably confined within the first mounting cavity 113, multiple limiting ribs 117 are provided on the cavity wall of the first mounting cavity 113. These limiting ribs 117 are evenly distributed along the inner wall of the first mounting cavity 113 to match the outer contour of the air pump 30. Each limiting rib 117 provides sufficient support without affecting the smooth insertion of the air pump 30. In addition, the surface of the limiting ribs 117 is usually smoothed to reduce friction and facilitate installation and disassembly. When the air pump 30 is fully embedded in the first mounting cavity 113, the limiting ribs 117 will conform to the outer wall of the air pump 30, forming multi-point contact, thereby firmly fixing the air pump 30 in the predetermined position. This design not only improves the installation accuracy but also enhances the stability of the air pump 30 in the working state, avoiding loosening or displacement caused by vibration or external impact.

[0062] Furthermore, an elastic pad can be added to the contact surface between the limiting rib 117 and the air pump 30 to further absorb vibration and reduce noise.

[0063] Combination Figure 4 and Figure 5 As shown, in one embodiment of this utility model, a second mounting cavity 114 is also formed inside the outer shell 11. The second mounting cavity 114 and the first mounting cavity 113 are arranged at intervals along the axial direction of the air pump 30. The air connector 122 and the water connector 121 are located in the second mounting cavity 114. The small portable hydration device 1 also includes a battery 40, which is installed in the second mounting cavity 114. Multiple air tubes 13 pass through the second mounting cavity 114 and are respectively connected to the air connector 122 and the water connector 121.

[0064] In this embodiment, the second mounting cavity 114 and the first mounting cavity 113 are arranged at intervals along the axial direction of the air pump 30 (i.e., as shown in the figure). Figure 4 The second mounting cavity 114 shown is located above the first mounting cavity 113. The second mounting cavity 114 is mainly used to accommodate the battery 40, the gas connector 122 and the water connector 121, 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.

[0065] Both the air connector 122 and the water connector 121 are located within the second mounting cavity 114, on the side closest to the nozzle 12. This arrangement not only simplifies the piping layout and reduces unnecessary bends and detours in the air pipe 13, but also facilitates inspection and maintenance.

[0066] Combination Figure 2 , Figure 4 and Figure 5As shown, in one embodiment of the present invention, the end of the outer shell 11 facing away from the air pump 30 is recessed to form an installation groove 115, and the water storage bullet 20 is detachably embedded in the installation groove 115 and connected to an air pipe 13.

[0067] In this embodiment, the mounting slot 115 is located at the end of the outer casing 11 away from the air pump 30, i.e., at the top of the small portable hydration device 1, and is situated on one side of the top of the small portable hydration device 1. This layout ensures that the water-filled cartridge 20 does not interfere with the working space of the air pump 30 and other components, while also facilitating user operation and maintenance. Furthermore, when the water-filled cartridge is embedded in the mounting slot 115, it is flush with the outer surface of the outer casing 11, thereby improving the aesthetic appearance and grip of the small portable hydration device 1.

[0068] The water-filled cartridge 20 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 20 as needed.

[0069] A sealing ring or rubber gasket is installed between the water-retaining bomb 20 and the mounting groove 115 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.

[0070] 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.
