Description

Technical Field

[0001] This application relates to the field of humidifier technology, and more particularly to a drying structure for a humidifier water tank. Background Technology

[0002] With the improvement of living standards, humidifiers have been widely used in homes and offices to regulate air humidity and improve dry environments. Humidifiers typically consist of core components such as a water tank, atomizer, and fan. The atomizer converts water into mist, which is then dispersed into the air by the fan. However, during use, water can easily remain in the water tank, and long-term accumulation can lead to bacterial growth or unpleasant odors, affecting user experience and health.

[0003] Currently, most humidifiers on the market lack effective drying functions, requiring users to manually clean and air-dry the water tank, a cumbersome and inefficient process. While some humidifiers feature simple air-drying functions, their poor structural design results in ineffective drying, failing to completely remove residual moisture from the water tank. Furthermore, in existing technologies, the air duct design typically does not consider connection to the water tank, preventing hot air from evenly covering the inside of the tank and further reducing drying efficiency.

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] like Figure 1 As shown, this application provides a drying structure for a humidifier water tank, including a base 1, a water tank 2, a ventilation device, and a heating device; the base 1 has a groove; the water tank 2 is disposed on the base 1 and forms a water trough 11 with the groove; the ventilation device is disposed on the base 1; the ventilation device includes a fan 5 and a first air duct 7, the fan 5 being disposed corresponding to the first air duct 7; the first air duct 7 is connected to the water tank 2; the heating device is disposed on the first air duct 7; wherein, the air blown out by the fan 5 is heated by the heating device and then enters the water tank 2 for drying the water tank 2.

[0035] The base 1 has a groove for accommodating the water tank 2. The water tank 2 is placed on the base 1, forming a water tank 11 together with the groove, for storing water for the humidifier. The ventilation device includes a fan 5 and a first air duct 7. The first air duct 7 is connected to the water tank 2, and the outlet of the first air duct 7 is higher than the liquid level in the water tank 11, ensuring that hot air can cover the inside of the water tank 2. The heating device is located inside the first air duct 7 and at the outlet of the fan 5. Preferably, the heating device typically uses a PTC heating element 6, which can generate stable hot air. Specifically, the heating device generates heat after being powered on, and the fan 5 blows air over the heating device to form hot air. The hot air enters the inside of the water tank 2 through the first air duct 7. Since the first air duct 7 is designed to rise, the hot air rises naturally, thus the first air duct 7 can effectively guide the hot air from the heating device to the cavity of the water tank 2. The hot air evenly covers the inside of the water tank 2, accelerating the evaporation of moisture and achieving rapid drying. Preferably, the air outlet of the first air duct 7 is higher than the liquid level of the water tank 11, ensuring that hot air can cover all parts of the water tank 2 and avoid moisture residue. Furthermore, the hot air not only accelerates moisture evaporation but also has a certain sterilization effect through high temperature, reducing the possibility of bacterial growth inside the water tank 2. In other words, through the combination of the heating device and the ventilation device, hot air can quickly enter the interior of the water tank 2, evenly covering all parts of the water tank 2, significantly improving drying efficiency.

[0036] In this embodiment, the heating device is a PTC heating element 6. It should be noted that the working principle of the PTC heating element 6 is based on its positive temperature coefficient characteristic; as the temperature increases, the resistance increases, thereby limiting the current and achieving automatic temperature regulation. Therefore, in this application, the PTC heating element 6 serves as a heat source, installed at the inlet of the air duct 7 and located at the outlet of the fan 5. When the drying function is activated, the PTC heating element 6 is powered on and heats up rapidly. The fan 5 blows air across the PTC heating element 6, forming a stable hot airflow. The heat generated by the PTC heating element 6 is then evenly distributed to the inside of the water tank 2 through the air duct 7, ensuring that all parts of the water tank 2 are covered by hot air. Working in conjunction with the fan 5, it achieves rapid drying of the water tank 2. Once the PTC heating element 6 reaches the set temperature, it automatically enters a constant temperature state, maintaining a stable hot air output and preventing overheating. Furthermore, the PTC heating element 6, air duct 7, and fan 5 are integrated into the base 1, making the overall structure compact and easy to install and maintain.

[0037] Specifically, after the humidifier is finished using, the user can activate the drying function of the water tank 2. At this time, the fan 5 and the PTC heating element 6 start working simultaneously; the PTC heating element 6 generates heat, and the fan 5 blows this heat upwards to the water tank 2 cavity through the air duct 7; the hot air circulates in the water tank 2, accelerating the evaporation of moisture, thereby achieving the purpose of drying the residual water stains in the water tank 2.

[0038] In this embodiment, the water tank 2 includes a top cover 21 and a body 22. The top cover 21 is located on top of the body 22 to enclose and form a cavity for containing liquid. The body 22 has a second air duct 12 communicating with the cavity, and the second air duct 12 is connected to the first air duct 7. The top cover 21 has a mist outlet. The top cover 21 and the body 22 are modularly designed for easy assembly and disassembly, allowing users to easily open the cavity of the water tank 2 for cleaning or maintenance. Furthermore, the mist outlet of the top cover 21 cooperates with the drying structure to ensure that no water mist remains during the drying process, keeping the mist outlet clean.

[0039] In this embodiment, the base 1 includes a base body 101 and a lower cover 102. The lower cover 102 is located on the side of the base body 101 facing the housing 21, and the lower cover 102 has the groove. The lower cover 102 and the bottom of the housing 22 enclose the water tank 11 for storing the water required by the humidifier. The ventilation device is located on the base body 101, wherein the first air duct 7 passes through the lower cover 102 and communicates with the second air duct 12, allowing air and hot air to enter the second air duct 12 through the first air duct 7, thereby realizing the ventilation and drying functions of the humidifier. Specifically, the rising air duct formed by the combination of the first air duct 7 and the second air duct 12 allows hot air to enter the second air duct 12 through the first air duct 7, and naturally rise and diffuse to the water tank 2, making full use of the rising characteristics of hot air to accelerate the evaporation of moisture, making it more evenly cover the inside of the water tank 2, and improving the drying efficiency. In addition, the water tank 11 is a water storage area formed by the housing 22, the lower cover 102 and the groove, which is used to store the water used by the humidifier. Even if the water in the water tank 11 is poured out, there may still be some water left. At this time, the first air duct 7 is set with a certain gap from the water tank 11, that is, the first air duct 7 does not directly contact the water tank 11, but introduces hot air into the water tank 11 through a certain spatial distance to dry the water tank 11.

[0040] In this embodiment, the lower cover 102 has a positioning protrusion on the side facing the second air duct 12. The positioning protrusion is inserted into the second air duct 12 to ensure precise positioning and a stable connection between the lower cover 102 and the second air duct 12, thereby improving the ease of assembly and the stability of the structure. The positioning protrusion has a clearance hole through which the first air duct 7 passes, allowing the first air duct 7 to smoothly pass through the positioning protrusion and connect with the second air duct 12, ensuring smooth airflow. The cooperation of the positioning protrusion and the clearance hole not only optimizes the connection structure of the air duct but also further improves the overall performance and reliability of the humidifier.

[0041] In this embodiment, the first air duct 7 includes a first connecting portion 71 and a second connecting portion 72 integrally connected. The first connecting portion 71 and the second connecting portion 72 are arranged at an angle, allowing the air duct to better adapt to the internal structural layout of the humidifier. The end of the first connecting portion 71 facing away from the second connecting portion 72 is connected to the fan 5, ensuring that the airflow generated by the fan 5 can smoothly enter the first air duct 7. The second connecting portion 72 passes through the clearance hole and communicates with the second air duct 12, thereby realizing air circulation. The heating device is disposed inside the first connecting portion 71. In addition, the end of the first connecting portion 71 facing away from the second connecting portion 72 is connected to the fan 5 for heating the air entering the air duct, thereby achieving a drying effect on the housing 22.

[0042] In this embodiment, the aperture size of the second connecting portion 72 gradually decreases in the direction away from the first connecting portion 71; wherein, the tapering of the first air duct 7 can accelerate the airflow speed, improve the efficiency of airflow, and also help reduce airflow noise and optimize the user experience.

[0043] In this embodiment, a flow guiding component is also included, comprising a mist guiding cylinder 8 and an atomizer 3. The mist guiding cylinder 8 is located in the receiving cavity and communicates with the mist outlet; the atomizer 3 is located in the water tank 11 and connected to the mist guiding cylinder 8. The mist guiding cylinder 8 guides the water mist generated by the atomizer 3 to the mist outlet, where it is ultimately released into the air. Besides humidifying, during the drying process, some hot air enters the water tank 11 to prevent water mist from stagnating and to dry the mist guiding cylinder 8 and the atomizer 3, preventing bacterial growth due to water mist retention and further improving the hygienic performance of the humidifier. It should be noted that during the drying process, hot air enters the water tank 2 through the first air duct 7, and the mist guiding cylinder 8 and the atomizer 3 need to have a certain degree of heat resistance to ensure they are not damaged during the drying process.

[0044] In this embodiment, the mist guide cylinder 8 includes a first cylinder 81 and a second cylinder 82. The first cylinder 81 is disposed in the receiving cavity and communicates with the mist outlet. The second cylinder 82 is disposed in the receiving cavity and communicates with the first cylinder 81. The second cylinder 82 is connected to the atomizer 3. The diameter of the first cylinder 81 is larger than the diameter of the second cylinder 82. More specifically, the diameter of the second cylinder 82 is smaller, while the diameter of the first cylinder 81 is larger. This segmented arrangement with different diameters optimizes the delivery efficiency and flow path of the water mist and hot air, allowing the water mist and hot air to be quickly delivered to the mist outlet, preventing water mist from lingering in the water tank 11 or the mist guide cylinder 8, and reducing the possibility of bacterial growth. In other words, during humidification, the mist guide cylinder 8 delivers the water mist generated by the atomizer 3 from the second cylinder 82 to the first cylinder 81, and finally releases it into the air through the mist outlet. During the drying process, hot air enters the water tank 11 through the gaps and then enters the first cylinder section 81 and the second cylinder section 82, ensuring that the water tank 11, the atomizer 3 and the mist guide cylinder 8 are all covered by hot air, achieving comprehensive drying, ensuring the internal dryness of each structure and avoiding bacterial growth due to water mist residue.

[0045] In this embodiment, a fog shield 9 is also included. Preferably, the fog shield 9 is typically designed as a mesh or a cover with small holes, which allows water mist to pass through while blocking larger water droplets or impurities. The fog shield 9 is located at the outlet of the second cylinder 82 and is situated in the first cylinder 81. The fog shield 9 is spaced apart from the mist outlet to ensure that the water mist can diffuse evenly after passing through the fog shield 9, avoiding direct impact on the mist outlet. It also prevents the water mist from flowing back into the mist guide cylinder 8 or atomizer 3 when the humidifier stops working, thus preventing water mist from stagnating in the mist guide cylinder 8 or atomizer 3.

[0046] It is important to understand that the segmented arrangement of the fog baffle 9 and the mist guide tube 8 (first section 81 and second section 82) further optimizes the flow path and distribution of the water mist. In other words, the fog baffle 9 allows hot air to pass through while simultaneously drying itself during the drying process, preventing water mist residue from causing bacterial growth. Specifically: During humidification, the water mist generated by the atomizer 3 enters the mist guide tube 8 through the second section 82. The water mist passes through the fog baffle 9, where larger water droplets or impurities are filtered out, and the fine water mist passes through the fog baffle 9, is evenly distributed, and is released into the air through the mist outlet. During the drying process, hot air dries the inside of the fog baffle 9 and the mist guide tube 8, and the hot air is finally discharged through the mist outlet, ensuring that the inside of the mist guide tube 8 and the fog baffle 9 is dry and preventing water mist residue from causing bacterial growth.

[0047] In this embodiment, a water level detector 4 is also included. The water level detector 4 is located inside the water tank 11 and is used to detect the water level in the water tank to determine whether the water level in the water tank 2 is sufficient. This ensures that the user can always know the water usage of the humidifier, while also preventing dry burning and improving safety. To further optimize the humidifier's automatic water replenishment function, the housing 22 and the water tank 11 are connected via a one-way valve. When the water level detector 7 detects a drop in the water level in the water tank 11, the system automatically adjusts the amount of water injected into the water tank 11 by controlling the opening and closing of the one-way valve, ensuring that the water level in the tank is always maintained at an appropriate level, thus achieving the effect of automatic water replenishment.

[0048] In this embodiment, the inner wall of the water tank 2 is coated with an antibacterial coating, which effectively inhibits the growth of bacteria and mold on the inner wall of the water tank 2, reducing microbial contamination. Simultaneously, the antibacterial coating effectively inhibits the growth of bacteria and mold, ensuring the cleanliness of the inside of the water tank 2 and preventing the water mist sprayed by the humidifier from carrying bacteria. Furthermore, the antibacterial coating, combined with the hot air drying function generated by the heating device, allows for rapid moisture removal, while the antibacterial coating provides long-term inhibition of bacterial growth. These two elements work synergistically to further enhance the antibacterial effect of the water tank 2.

[0049] In this embodiment, a plug-in structure 10 is also included, which includes a plug-in part and a plug-in slot. The plug-in slot is located at the bottom of the water tank 2, and the plug-in part is located on the base 1. The plug-in part is electrically connected to the plug-in slot to energize the water tank 2. The plug-in part, located on the base 1, typically includes conductive contacts or pins for connecting to the plug-in slot and transmitting electrical energy. The plug-in slot, located at the bottom of the water tank 2, typically includes a conductive interface or socket for connecting to the plug-in part and receiving electrical energy. Through the connection between the plug-in part and the plug-in slot, the base 1 supplies power to the water tank 2, ensuring that the electrical components (such as the atomizer 3, water level detector 4, etc.) inside the water tank 2 can function normally. Specifically, the user aligns the connector slot at the bottom of the water tank 2 with the connector on the base 1 and presses gently to ensure a tight connection between the connector and the slot. After the connector is connected, the base 1 supplies power to the water tank 2 through the connector structure 10, ensuring the normal operation of the electrical components inside the water tank 2. When the user needs to disassemble the water tank 2, simply lift the water tank 2 gently to separate the connector from the slot, thus completing the disassembly. Furthermore, the conductive parts of the connector structure 10 are waterproof, effectively preventing moisture from entering and causing short circuits or damage.

[0050] In this embodiment, the base 1 is equipped with support feet at its bottom, ensuring that the humidifier is placed stably on a table or the ground, preventing the device from tipping over or leaking water due to shaking or tilting. The support feet are typically made of non-slip material, which increases the friction between the humidifier and the contact surface, preventing the device from sliding. In addition, the support feet separate the bottom of the base 1 from the contact surface by a certain distance, preventing the bottom of the base 1 from directly contacting water stains or damp surfaces, and preventing electrical components from getting damp.
