Specific Embodiments
[0021] To make the purposes, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model.
[0022] Such as Figures 1 to 4As shown in the figure, a long-term moisturizing wet tissue bag includes a wet tissue bag body 1 and a liquid storage box 12 installed in the inner cavity of the wet tissue bag body 1. The liquid storage box 12 is installed on the inner wall of the top of the wet tissue bag body 1. The side wall of the liquid storage box 12 is connected with an air bag 6 for extruding the temporarily stored liquid in the liquid storage box 12. A second one-way valve 10 is installed between the air bag 6 and the liquid storage box 12. An air inlet pipeline 7 is connected to the air bag 6. A first one-way valve 8 is installed on the air inlet pipeline 7. A plurality of liquid outlets 13 are arranged on the liquid storage box 12. In the present arrangement, the wet tissue bag body 1 serves as the shell of the entire device, containing and protecting the internal components, storing wet tissues, and providing the liquid required for wetting the wet tissues. The air bag 6 generates air pressure changes by pressing, and is used to extrude the temporarily stored liquid in the liquid storage box 12, realizing on-demand liquid supply. The second one-way valve 10 is installed between the air bag 6 and the liquid storage box 12, ensuring that air can only flow from the air bag 6 to the liquid storage box 12, preventing liquid from flowing back into the air bag 6. The air inlet pipeline 7 connects the air bag 6 with the outside world, supplying air to the air bag 6. The first one-way valve 8 is installed on the air inlet pipeline 7, ensuring that air can only flow into the air bag 6 in one direction, maintaining the normal operation of the air bag. The liquid outlets 13 are arranged on the liquid storage box 12, allowing the liquid in the liquid storage box 12 to flow out and soak the wet tissues.
[0023] As shown in the figure, Figures 1 to 4 In the specific embodiment, the air bag 6 is installed on the inner wall of the top of the wet tissue bag body 1. An air outlet pipeline 9 is connected to the air bag 6. A connecting pipeline 11 is connected to the liquid storage box 12. The second one-way valve 10 is connected between the air outlet pipeline 9 and the connecting pipeline 11. In the present arrangement, the air bag 6 is connected to the connecting pipeline 11 and the liquid storage box 12 through the air outlet pipeline 9. When pressed, the air bag 6 releases air, causing the air pressure in the liquid storage box 12 to rise and pushing the liquid to flow out. The second one-way valve 10 ensures that air can only flow from the air outlet pipeline 9 to the liquid storage box 12 in one direction, preventing the air and liquid in the liquid storage box 12 from flowing in the opposite direction.
[0024] As shown in the figure, Figures 1 to 4 Further, a base 2 is installed on the top of the wet tissue bag body 1. A hinged cover 3 is hinged to the base 2. In the present arrangement, the base 2 is installed on the top of the wet tissue bag body 1, providing a hinged support point for the hinged cover 3. The hinged cover 3 can be opened and closed, making it convenient for users to access the wet tissues while reducing the contact between the inside and the outside air, thereby reducing the evaporation of liquid.
[0025] As shown in the figure, Figures 1 to 4 A wet tissue extraction opening 4 is formed on the wet tissue bag body 1. A sealing tab 5 is arranged above the wet tissue extraction opening 4. In the present arrangement, the wet tissue extraction opening 4 is used by users to extract wet tissues. After the wet tissues are extracted, the sealing tab 5 reseals the wet tissue extraction opening 4, preventing the evaporation of liquid and the entry of dust and other impurities.
[0026] As shown in the figure, Figures 1 to 4As shown, the liquid storage box 12 is in a zigzag shape, and RO pure water is stored in the liquid storage box 12. In this setting, the zigzag structure of the liquid storage box 12 is conducive to the surrounding distribution of the liquid, uniformly wetting the wet wipes around, and the stored RO pure water has high purity, which can effectively avoid the influence of impurities on the wet wipes and the skin.
[0027] As Figures 1 to 4 shown, a pressing mark 14 is printed on the main body 1 of the wet wipe bag, and the pressing mark 14 is arranged directly above the airbag 6. In this setting, the pressing mark 14 is arranged directly above the airbag 6, which facilitates the user to quickly find the position of pressing the airbag 6 and makes the operation more convenient.
[0028] The implementation principle of a wet wipe bag with long-term moisture retention in this embodiment is as follows: In the initial state, inside the main body 1 of the wet wipe bag, pure RO pure water is stored in the liquid storage box 12. At this time, both the first one-way valve 8 and the second one-way valve 10 are in a tightly closed state to prevent the random flow of gas and liquid. The opening and closing cover 3 is closed, and the sealing sticker 5 covers the wet wipe outlet 4, minimizing the contact between the internal liquid and the external air to the greatest extent and inhibiting the liquid volatilization. When the user perceives that the wet wipe is dry and needs to replenish moisture, they can accurately find the airbag 6 according to the pressing mark 14 on the main body 1 of the wet wipe bag and perform a pressing operation. As the pressing action progresses, the airbag 6 is extruded by an external force, and the gas pressure inside it increases rapidly. Under the action of this pressure difference, the second one-way valve 10 at one end of the air outlet pipe 9 opens, and the gas in the airbag 6 flows into the liquid storage box 12 along the air outlet pipe 9 and the connecting pipe 11, causing the internal air pressure of the liquid storage box 12 to increase. Under the push of the air pressure, the RO pure water in the liquid storage box 12 flows out evenly from multiple liquid outlets 13, precisely wetting the wet wipes below. The second one-way valve 10 can effectively prevent the liquid from flowing back into the airbag 6, ensuring the unidirectionality and stability of the entire liquid supply process. When the user releases the airbag 6, the airbag 6 quickly restores its deformation by virtue of its good elasticity, and a negative pressure environment is immediately formed inside. At this time, the first one-way valve 8 on the air inlet pipe 7 automatically opens under the pressure difference formed by the external atmospheric pressure and the negative pressure inside the airbag, and the external air smoothly flows into the airbag 6 along the air inlet pipe 7, prompting the airbag 6 to quickly return to the initial state, making full preparations for the next pressing liquid supply operation. During daily use, as long as the opening and closing cover 3 is always kept closed and the sealing sticker 5 covers the wet wipe outlet 4, the liquid volatilization can be effectively prevented, ensuring that the liquid in the wet wipe bag always maintains an appropriate amount, providing a reliable guarantee for the long-term moisture retention of the wet wipes.
