Technical Field

[0001] This utility model belongs to the field of humidifier technology, and in particular relates to a dual-head mist-free humidifier. Background Technology

[0002] Humidifiers, as small household appliances that conveniently adjust indoor humidity, are widely used in daily life. Humidifiers humidify the indoor environment by blowing out water mist. Currently, most humidifiers are single-head humidifiers, resulting in low humidification efficiency. A patent application with publication number CN219550729U discloses a pure humidifier with a dual-fan structure. Through the design of dual fans and dual evaporation cores, it can activate two fans simultaneously as needed to improve humidification efficiency. However, due to the rapid consumption of water during dual-start humidification, and the fact that the air inlet of the humidifier is located on the side wall of the water tank, the water added to the tank cannot exceed the air inlet, resulting in a limited water capacity. This leads to short battery life, the need for frequent water refills, and inconvenience in use. Summary of the Invention

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] Specific embodiments, such as Figure 1-5 The illustrated dual-head mist-free humidifier includes: a water tank 1 with an upward-facing water tank cavity 2; two filter evaporation cores 3 arranged opposite each other within the water tank cavity 2; and a dual-fan unit 4, comprising a mounting bracket 41 positioned at the opening of the water tank 1, and two fan wheels 42 rotatably mounted on the mounting bracket 41 and corresponding to the two filter evaporation cores 3, respectively. An air inlet 5 is formed between the mounting bracket 41 and the edge of the opening of the water tank 1. In use, water is added to the water tank, and the fan wheels are activated to allow airflow into the air inlet. The airflow is then evaporated into water vapor by the filter evaporation cores and discharged. The dual-fan operation results in high humidification efficiency, and the air inlet's location at the edge of the opening of the water tank allows for a larger water storage capacity, longer operating time, and greater ease of use.

[0019] Specifically, the water tank 1 includes a tank body 11 and a cover 12 with an opening on the tank body 11. The cover 12 has two opposing clearance openings 6 for the two filter evaporation cores 3 to pass through, a supporting protrusion 7 on the periphery of the clearance openings 6 for supporting the dual wind turbine unit 4, and a ventilation opening 8 on the periphery of the clearance openings 6. In use, water is added to the tank body 11, and then the dual wind turbine unit 4 is placed on the cover 12 and supported by the supporting protrusion 7. The dual wind turbine unit 4 is raised by the supporting protrusion 7, so that an air inlet 5 is formed between the mounting bracket 41 and the edge of the opening on the water tank 1. There is no need to set an air inlet hole on the outer wall of the tank body 11, which makes the water tank have a higher water storage capacity and a longer operating time.

[0020] Furthermore, the lid 12 is detachably mounted on the box body 11. The inner wall of the box body 11 has a lid limiting notch 91, and the edge of the lid 12 has a lid limiting flange 92 corresponding to and matching the lid limiting notch 91. The inner wall of the box body 11 also has a first connecting hole 10, and the lid 12 has a second connecting hole 13. When the lid limiting flange 92 is engaged in the lid limiting notch 91, the first connecting hole 10 and the second connecting hole 13 correspond. The lid 12 is detachably mounted on the box body 11, facilitating cleaning of the box body 11. Moreover, the lid limiting flange 92 and the lid limiting notch 91 work together to align the first connecting hole 10 and the second connecting hole 13, making installation more convenient.

[0021] Furthermore, a viewing window 14 is provided on the side wall of the water tank 1. The viewing window 14 is an oblong-shaped viewing window arranged in the vertical direction, used to observe the water level in the water tank 1.

[0022] More specifically, the bottom of the water tank 1 is provided with two opposing filter element limiting protrusions 15, and the mounting bracket 41 is provided with two opposing filter element limiting slots 16 on the side near the water tank 1. One end of each of the two filter evaporation elements 3 is respectively fitted onto the corresponding filter element limiting protrusion 15, and the other end is respectively locked into the corresponding filter element limiting slot 16. This allows the two filter evaporation elements 3 to be positioned and fixed after the dual turbine unit 4 is installed on the water tank 1.

[0023] Furthermore, the dual-head mist-free humidifier also includes a float rod 17. The mounting bracket 41 has a first guide groove 18, and the bottom of the water tank 1 has a second guide groove 19 corresponding to the first guide groove 18. One end of the float rod 17 extends movably into the first guide groove 18, and the other end extends movably into the second guide groove 19. A magnet mounting groove 20 is provided on the end of the float rod 17 extending into the first guide groove 18. A magnet is fixedly installed in the magnet mounting groove 20 with screws. A Hall switch is installed at a position on the mounting bracket 41 relative to the first guide groove 18. When the water level is sufficient, the float rod 17 floats in the second guide groove 19, causing the magnet to contact the Hall switch. When the water level in the tank is insufficient, the float rod 17 moves downward, causing the magnet to move away from the Hall switch, thus sensing the water shortage.

[0024] Furthermore, the mounting bracket 41 has an air inlet slot 21 arranged circumferentially on the periphery of one end of the bracket that extends into the water tank cavity 2.

[0025] Specifically, the dual wind turbine unit 4 also includes an upper cover 43 on the mounting frame 41. The upper cover 43 is provided with two air outlets 22 respectively arranged opposite to the wind turbine 42. The side of the upper cover 43 away from the wind turbine 42 is provided with an air outlet grid 23. A plurality of air outlet grids 23 are arranged in parallel and in a row.

[0026] More specifically, the upper cover 43 is provided with a socket panel 24 and a display panel 25 on its periphery.

[0027] Additionally, a UV disinfection lamp 26 is provided on the side of the mounting bracket 41 facing the filter evaporation core 3. The UV disinfection lamp 26 includes a mounting plate 101, a PCB board 102 disposed on the mounting plate 101, a UV lamp core 103 disposed on the PCB board 102, and a lamp cover 104 disposed on the mounting plate 101. The mounting plate is embedded in the groove 105 of the mounting bracket 41 and is fixedly connected by screws. This achieves disinfection of water vapor in the filter evaporation core 3.
