Description

Technical Field

[0001] This application relates to the field of electrical appliances, and in particular to a lift-up humidifier. Background Technology

[0002] In modern home and office environments, humidifiers, as devices that effectively regulate indoor humidity, are widely used to improve air quality and alleviate the discomfort caused by dryness. Among them, vaporization humidifiers, due to their unique humidification principle—absorbing water from the tank through absorbent cotton (or similar porous materials) and using natural evaporation or fan assistance to accelerate the vaporization of the water—have achieved a more natural and healthy humidification effect, making them popular with consumers.

[0003] However, traditional vaporization humidifiers, especially those designed for miniaturization, are typically equipped with only a single water tank due to their size limitations. This design has significant shortcomings in water level management. When the water level in the tank is high, more of the absorbent cotton is submerged in water, correspondingly reducing the effective surface area exposed to the air for moisture vaporization. This directly leads to a decrease in humidification efficiency, making it difficult to meet users' needs for rapid humidification in different humidity environments.

[0004] Furthermore, when humidification is not needed or the user does not use the humidifier for a long time, the absorbent cotton is constantly soaked in water, which not only accelerates the aging process of the material and shortens the service life of the absorbent cotton, but also provides a breeding ground for microorganisms such as bacteria and mold, posing a potential threat to the user's health.

[0005] Therefore, in response to the above problems, developing a small vaporization humidifier that can intelligently adjust the working state of the absorbent cotton, optimize humidification efficiency, extend product lifespan, and protect user health has become a pressing technical issue in the industry.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

Detailed Implementation

[0042] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0044] Existing small vaporization humidifiers are small in size and have only one water tank. When the water level in the tank is high, the area of ​​the absorbent cotton exposed to the air is small, that is, the vaporization area is small, resulting in an unsatisfactory humidification effect. At the same time, when humidification is not needed, the absorbent cotton is still soaked in water, which can easily shorten its service life and breed bacteria.

[0045] To address the aforementioned technical problems, this embodiment provides a lifting humidifier. (See reference...) Figures 1 to 4 As shown, Figure 1 This is a top view of the lifting humidifier in the embodiment of this application. Figure 2 yes Figure 1 Cross-sectional perspective view of section A. Figure 3 yes Figure 1 sectional perspective view of section B. Figure 4 This is a perspective view of the lifting component in the embodiments of this application.

[0046] A lifting humidifier includes a shell 1, a lifting component 2, absorbent cotton 5, and a lifting mechanism 4.

[0047] A water tank 11 is provided inside the outer casing 1; a lifting component 2 is connected to the outer casing 1 via a guide structure 3, which is configured to guide the lifting component 2 to move along the height direction of the water tank 11; absorbent cotton 5 is located inside the outer casing 1 and is connected to the lifting component 2; a lifting mechanism 4 is installed on the outer casing 1 and connected to the lifting component 2, and is configured to drive the lifting component 2 to move along the height direction of the water tank 11 to adjust the height of the absorbent cotton 5 relative to the water tank 11; wherein, when the absorbent cotton 5 moves to the maximum height, the absorbent cotton 5 separates from the water in the water tank 11.

[0048] In some embodiments of the lifting mechanism 4, see [reference]. Figure 2 and Figure 3 As shown, the lifting mechanism 4 includes a motor 41 and a lead screw 42. The lead screw 42 is rotatably connected to the housing 1 and is vertically positioned. The motor 41 is mounted on the housing 1 and is connected to the lead screw 42 for transmission. The lifting component 2 is provided with a vertically extending threaded hole 21 and is screwed to the lead screw 42 through the threaded hole 21. The guide structure 3 is also configured to restrict the rotation of the lifting component 2 around the lead screw 42. After the motor 41 starts, it drives the lead screw 42 to rotate through the transmission components. Since the lifting component 2 is restricted by the guide structure 3 and cannot rotate around the lead screw 42, according to the lead screw transmission principle, the rotation of the lead screw 42 is converted into the vertical movement of the lifting component 2 along the lead screw 42. This design enables the lifting component 2 to be stably and accurately adjusted in the vertical direction, providing reliable power support and a motion basis for subsequent adjustment of the height of the absorbent cotton 5.

[0049] Furthermore, in addition to using existing transmission methods, the drive connection between motor 41 and lead screw 42 can also be achieved in the following ways: (See [reference]) Figure 2 and Figure 3As shown, the lifting mechanism 4 also includes a driving gear 43, a driven gear 44, and a bearing 45. The outer casing 1 is provided with a bearing groove 12, and a through hole 121 is provided in the middle of the bearing groove 12. The bearing 45 is installed on the bearing groove 12 of the outer casing 1. A connecting shaft 421 is provided at the top of the lead screw 42. The connecting shaft 421 passes through the through hole 121 and is connected to the bearing 45. The driven gear 44 is fixedly connected to the top of the connecting shaft 421. The driving gear 43 is driven by the driven gear 44 and is connected to the motor 41. The motor 41 drives the driving gear 43 to rotate, and the driving gear 43 transmits power to the driven gear 44. The driven gear 44 drives the connecting shaft 421 to rotate, which in turn drives the lead screw 42 to rotate. This gear transmission structure can realize the power transmission and speed conversion between the motor 41 and the lead screw 42. For example, by reasonably selecting the gear ratio, the rotation speed of the lead screw 42 can be adjusted, thereby controlling the moving speed of the lifting component 2, meeting the needs of different usage scenarios for adjusting the height of the absorbent cotton 5, and improving the flexibility and adaptability of the lifting mechanism 4.

[0050] In some implementations of guide structure 3, see Figure 3 and Figure 4 As shown, the guide structure 3 includes a guide block 31 disposed on the outside of the lifting component 2 and a guide groove 32 disposed on the inside of the outer casing 1. The guide groove 32 extends vertically, and the guide block 31 is slidably disposed within the guide groove 32. The cooperation between the guide block 31 and the guide groove 32 effectively restricts the rotation of the lifting component 2 around the lead screw 42, ensuring that the lifting component 2 can only move in a vertical straight line along the lead screw 42. This design improves the stability and accuracy of the movement of the lifting component 2, avoids swaying or deviation of the lifting component 2 during movement, ensures the accuracy of the height adjustment of the absorbent cotton 5, and helps maintain the normal and stable working state of the humidifier.

[0051] In other embodiments of the guide structure 3, the guide structure 3 may also be a guide post provided on the outer shell 1 and a guide hole provided on the lifting member 2, wherein the guide hole and the guide post extend vertically and are slidably engaged.

[0052] In some embodiments of the lifting component 2, see [reference]. Figure 2 and Figure 4As shown, the lifting component 2 includes a connecting part 22 connected to the lifting mechanism 4, an outer wall 23 connected to the outer shell 1 via a guide structure 3, and a connecting rib 24 fixedly connected between the outer wall 23 and the connecting part 22; an airflow channel 25 is provided between the connecting part 22, the outer wall 23, and the connecting rib 24; the absorbent cotton 5 is connected to the bottom of the outer wall 23. This configuration allows the lifting component 2 to move vertically as the lead screw 42 rotates, thanks to the screw 42's screw-on connection. The outer wall 23 is connected to the outer shell 1 via the guide structure 3, ensuring the stability of the lifting component 2's movement. The connecting rib 24 enhances the overall structural strength of the lifting component 2, enabling it to withstand the weight of the absorbent cotton 5 and various stresses generated during movement, while also driving the outer wall 23 to move. The airflow channel 25 facilitates air circulation within the lifting component 2, improving the contact efficiency between the air and the absorbent cotton 5, thereby enhancing the humidification effect.

[0053] Further, see Figure 2 and Figure 4 As shown, the connecting part 22 is provided with a threaded hole 21 that is screwed onto the lead screw 42. The connecting part 22 of the lifting component 2 is screwed onto the lead screw 42 through the threaded hole 21, so as to achieve a reliable connection with the lifting mechanism 4 and ensure that the lifting component 2 can move vertically stably as the lead screw 42 rotates.

[0054] In some embodiments where the outer wall 23 is connected to the absorbent cotton 5, see [reference needed]. Figure 2 and Figure 4 As shown, the bottom of the outer wall 23 is provided with an inwardly extending annular inner edge 231, and the annular inner edge 231 is provided with a plurality of circumferentially evenly distributed slots 232; the top of the absorbent cotton 5 is provided with an installation block 51, and the top of the installation block 51 is provided with a buckle 52 that is detachably connected to the slots 232. The detachable connection between the slots 232 and the buckles 52 allows the absorbent cotton 5 to be installed and removed conveniently and quickly. When the absorbent cotton 5 needs to be replaced or cleaned after a period of use, the user only needs to remove the buckles 52 from the slots 232 to easily remove the absorbent cotton 5. This design reduces the difficulty of use for users, improves the maintenance convenience of the humidifier, and also makes it easy for users to replace absorbent cotton 5 of different specifications or materials according to actual needs.

[0055] In some implementations, see Figure 2 and Figure 3As shown, the lifting humidifier also includes a fan 6, which is installed at the bottom of the connecting part 22 and below the connecting rib 24. The fan 6 can move vertically inside the water tank 11. For example, the fan 6 can be installed and fixed by setting a corresponding mounting base 61 at the bottom of the connecting part 22, and the maximum external dimension of the fan 6, such as the rotation diameter of its blades, is smaller than the inner diameter of the water tank 11, allowing it to move vertically within a certain range inside the water tank 11. The airflow generated by the fan 6 can accelerate the flow of air in the internal channel 25 of the lifting part 2 and around the absorbent cotton 5, improving the efficiency of moisture exchange between the air and the absorbent cotton 5, thereby enhancing the humidification effect. The design that the fan 6 can move vertically inside the water tank 11 with the connecting part 22 allows the fan 6 to be adjusted according to the height position of the absorbent cotton 5, ensuring that the airflow can act evenly and effectively on the absorbent cotton 5, further improving the uniformity and efficiency of humidification.

[0056] In some implementations, see Figure 2 and Figure 3 As shown, the outer casing 1 includes a bottom casing 13 and a top casing 14 mounted on the bottom casing 13. The bottom casing 13 and the top casing 14 can be connected by snap-fit, screw connection, or other methods, facilitating user disassembly and installation. The bottom casing 13 houses a water tank 11, and the lifting mechanism 4 is mounted on the top casing 14. The split-type outer casing 1 design facilitates the assembly and maintenance of the humidifier. The connection between the bottom casing 13 and the top casing 14 can be made by snap-fit, screw connection, or other methods, facilitating user disassembly and installation. The water tank 11 is located inside the bottom casing 13, which allows for centralized management of humidification water and facilitates user operations such as adding and draining water. The lifting mechanism 4 is mounted on the top casing 14, making the lifting mechanism 4 relatively independent from the water tank 11, reducing the impact of water in the water tank 11 on the lifting mechanism 4, and improving the reliability and service life of the lifting mechanism 4.

[0057] Further, see Figure 2 As shown, the bottom shell 13 has multiple vent holes 15 above the water tank 11. The absorbent cotton 5 can be vertically moved to be horizontally aligned with the distribution area of ​​the multiple vent holes 15, that is, the portion of the absorbent cotton 5 above the water level in the water tank 11 is aligned with the position of the vent holes 15. The vent holes 15 can accelerate the airflow speed in the absorbent cotton area, thereby accelerating water evaporation and improving humidification efficiency.

[0058] In operation, the lifting mechanism 4 of this application can precisely drive the lifting component 2 to move vertically, thereby causing the absorbent cotton 5 to move vertically in sync. This allows for flexible adjustment of the height of the absorbent cotton 5 relative to the water tank 11. This height adjustment mechanism ensures that the effective area of ​​the absorbent cotton 5 for moisture vaporization in the air is always at its optimal level, significantly improving humidification efficiency and fully meeting users' actual needs for rapid humidification in different scenarios.

[0059] Equally important, when the absorbent cotton 5 moves to its maximum height, it completely separates from the water in the water tank 11. This design has multiple positive effects: firstly, it effectively drains excess water absorbed by the absorbent cotton 5, greatly slowing down the aging process of the absorbent cotton 5 material, significantly extending its service life, and reducing user operating costs; secondly, it greatly reduces the environment for bacterial growth on the absorbent cotton 5, ensuring the health and safety of the water in the water tank 11 from the source, providing users with a healthier and more comfortable humidification experience.

[0060] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
