Description

Technical Field

[0001] This utility model relates to the field of wet wipes technology, specifically a self-heating wet wipe that can be used for both hot and cold applications. Background Technology

[0002] Wet wipes are a type of tissue made from pure water, non-woven fabric, and propylene glycol, used for wiping the face, hands, or skin. In cold weather, such as winter, direct contact with wet wipes can cause discomfort, especially when wiping infants or patients, potentially leading to them catching a cold. Therefore, heating wet wipes has become a new demand.

[0003] There are some wet wipe heating devices on the market that can heat wet wipes all at once using a heating pack. However, after heating, the wet wipes will cool down naturally after a period of time and cannot be heated again, making it impossible to achieve segmented heating and thus impractical. To address this issue, we propose a self-heating wet wipe that can be used for both heating and cooling. Utility Model Content

[0004] The purpose of this invention is to provide a self-heating wet wipe that can be used for both hot and cold applications, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-heating wet wipe that can be used for both hot and cold applications, comprising a box body and a box lid. The box body is provided with a heating mechanism for heating the wet wipe. The heating mechanism includes a heat-conducting plate, a heating pack is provided on the top of the heat-conducting plate, and a water storage tank is provided on the top of the box body. Heat is generated by the chemical reaction between the water in the water storage tank and the heating pack to heat the wet wipe.

[0006] The top and bottom of the water storage tank are respectively connected to a segmented water pumping mechanism and a water distribution mechanism for evenly dripping water onto the heating pack.

[0007] In a further preferred embodiment, the segmented pumping mechanism includes a pressure plate, which is slidably connected to the inner wall of the water storage tank. A screw is rotatably connected to the top of the pressure plate via a bearing. The top end of the screw extends to the outside of the water storage tank and is fixedly connected to a knob. The screw is threadedly connected to the water storage tank.

[0008] In a further preferred embodiment, the top of the box body, the heat-conducting plate, and the heating pack are all provided with through holes for easy access to the wet wipes. The size of the through holes is smaller than that of the box lid, and a protective cylinder is fixedly connected to the inner wall of the through holes. The protective cylinder is designed to prevent the user from being burned when taking them out.

[0009] More preferably, the water distribution mechanism includes a one-way outlet valve, the top of which is connected to the water storage tank, and the bottom of which is connected to a U-shaped diversion pipe. The end of the U-shaped diversion pipe away from the water storage tank is inclined downwards, and multiple outlet holes are opened at the bottom of the U-shaped diversion pipe.

[0010] More preferably, the bottom of the box is provided with a support plate for placing wet wipes. Two dampers are fixedly connected to the bottom of the support plate. The movable end of the damper is fixedly connected to the inner wall of the bottom of the box. A spring is fixedly connected between the support plate and the box, and the spring is movably sleeved on the outside of the damper.

[0011] More preferably, a temperature display is connected to the top of the box.

[0012] More preferably, a temperature sensor is connected to the top of the heat-conducting plate, and the temperature display is electrically connected to the temperature sensor via a wire.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: After a certain amount of wet wipes is taken out, the weight on the support plate is reduced, and the spring drives the support plate to move upward, thus facilitating the taking out while ensuring contact between the wet wipes and the heat-conducting plate. When it is necessary to heat the wet wipes, the knob is rotated, and the knob drives the screw to move downward. The screw drives the pressure plate to slide downward in the water tank and pressurizes the water in the water tank, causing the one-way water outlet valve to open. The water flows through the water outlet hole at the bottom of the U-shaped diverter and drips evenly onto the top of the heating pack. Heat is generated through the chemical reaction between the water and the heating pack and is conducted to the top wet wipes through the heat-conducting plate. The heating temperature and time can be adjusted by rotating the knob multiple times. Multiple rotations can also control the multiple pumping of water to achieve multiple heating, avoiding the inconvenience caused by natural cooling after one heating. The temperature sensor detects the temperature after heating and displays it on the temperature display, which is convenient for users to read directly. It is more practical and safer.

[0021] Example

[0022] Please see Figure 1-5 This utility model provides a technical solution: a self-heating wet wipe that can be used for both hot and cold applications, including a box body 1 and a box cover 2. The box body 1 is provided with a heating mechanism for heating the wet wipe. The heating mechanism includes a heat-conducting plate 3, a heating pack 4 is provided on the top of the heat-conducting plate 3, and a water storage tank 5 is provided on the top of the box body 1. The water filled in the water storage tank 5 reacts chemically with the heating pack 4 to generate heat to heat the wet wipe.

[0023] The top and bottom of the water tank 5 are respectively connected to a segmented water pumping mechanism and a water distribution mechanism for evenly dripping water onto the heating pack 4. In use, open the lid 2 and reach into the protective cylinder 16 to retrieve the wet wipes. After retrieving a certain amount of wet wipes, the weight on the support plate 11 is reduced, and the spring 13 moves the support plate 11 upwards, facilitating retrieval while ensuring contact between the wet wipes and the heat-conducting plate 3. When heating the wet wipes is required, rotate the knob 8. The knob 8 moves the screw 7 downwards, and the screw 7 causes the pressure plate 6 to slide downwards within the water tank 5, pressurizing the water in the tank and allowing unidirectional flow. When the water valve 9 is opened, water flows through the outlet hole at the bottom of the U-shaped diverter 10 and drips evenly onto the top of the heating pack 4. Heat is generated through the chemical reaction between the water and the heating pack 4, and the heat is conducted to the top wet towel through the heat conduction plate 3. The heating temperature and time can be adjusted by rotating the knob 8. Multiple rotations can also control the multiple pumping of water to achieve multiple heating, avoiding the inconvenience caused by natural cooling after a single heating. The temperature sensor 15 detects the temperature after heating and displays it on the temperature display 14, which is easy for the user to read directly, making it more practical and safer.

[0024] In this embodiment, specifically: the segmented pumping mechanism includes a pressure plate 6, which is slidably connected to the inner wall of the water storage tank 5. The top of the pressure plate 6 is rotatably connected to a screw 7 via a bearing. The top of the screw 7 extends to the outside of the water storage tank 5 and is fixedly connected to a knob 8. The screw 7 is threadedly connected to the water storage tank 5.

[0025] In this embodiment, specifically: the top of the box body 1, the heat conduction plate 3 and the heating pack 4 are all provided with through holes 17 for easy access to the wet wipes. The size of the through holes 17 is smaller than that of the box cover 2. A protective cylinder 16 is fixedly connected to the inner wall of the through holes 17. The protective cylinder 16 is designed to prevent the user from being burned when taking it out.

[0026] In this embodiment, specifically: the water distribution mechanism includes a one-way outlet valve 9, the top of the one-way outlet valve 9 is connected to the water storage tank 5, the bottom of the one-way outlet valve 9 is connected to a U-shaped diversion pipe 10, the end of the U-shaped diversion pipe 10 away from the water storage tank 5 is inclined downward, and multiple water outlet holes are opened at the bottom of the U-shaped diversion pipe 10.

[0027] In this embodiment, specifically: the bottom of the box body 1 is provided with a support plate 11 for placing wet wipes. Two dampers 12 are fixedly connected to the bottom of the support plate 11. The movable end of the damper 12 is fixedly connected to the inner wall of the bottom of the box body 1. A spring 13 is fixedly connected between the support plate 11 and the box body 1. The spring 13 is movably sleeved on the outside of the damper 12.

[0028] In this embodiment, specifically: a temperature display 14 is connected to the top of the box 1. The temperature display 14 is a TM1637, a 4-digit LED digital tube display module.

[0029] In this embodiment, specifically: a temperature sensor 15 is connected to the top of the heat-conducting plate 3, and a temperature display 14 is electrically connected to the temperature sensor 15 via a wire. The temperature sensor 15 is a DS18B20 with a temperature measurement range of -55℃ to +125℃.

[0030] In operation, this invention works as follows: When in use, open the lid 2 and reach into the protective tube 16 to retrieve the wet wipes. After retrieving a certain amount of wet wipes, the weight on the support plate 11 decreases, and the spring 13 moves the support plate 11 upwards, facilitating retrieval while ensuring contact between the wet wipes and the heat-conducting plate 3. When heating the wet wipes is required, rotate the knob 8. The knob 8 moves the screw 7 downwards, causing the pressure plate 6 to slide downwards within the water tank 5, pressurizing the water in the tank. This opens the one-way outlet valve 9, allowing water to flow through the U-shaped diverter pipe 1. The water outlet at the bottom of the heating pack 4 evenly drips onto the top of the heating pack 4, thereby generating heat through the chemical reaction between the water and the heating pack 4. The heat is then conducted to the top wet towel via the heat conduction plate 3. The heating temperature and time can be adjusted by rotating the knob 8 multiple times. Multiple rotations can also control the pumping of water multiple times to achieve multiple heating, avoiding the inconvenience caused by natural cooling after a single heating. The temperature sensor 15 detects the temperature after heating and displays it on the temperature display 14, making it easy for users to read directly. This enhances practicality and safety.
