[0017] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0018] The problem with conventional evaporative humidifiers using water pumps is that the pump's live parts and the wires connecting the pump to the control board are submerged in water, posing a risk of short circuits due to water ingress. The conventional approach to solving this problem is to strengthen the waterproof sealing of the live parts and wires. The inventors of this invention, referencing the structure of the Archimedes screw pump, directly redesigned the pump's structure, placing the live parts and wires outside the water tank.

[0019] This utility model provides a humidifier; please refer to [reference needed]. Figure 1 The humidifier includes a support frame 3, a water pipe 4, and a water tank 1, a humidifying mesh 2, and a power source 5 arranged sequentially from bottom to top along the height of the humidifier. The support frame 3 is inserted obliquely into the water tank 1, and the water pipe 4 is spirally wound and fixed to the support frame 3. The power source 5 is connected to the support frame 3 to make the support frame 3 rotate. The water pipe 4 has a water inlet 41 and a water outlet 42. The water inlet 41 is located inside the water tank 1, and the water outlet 42 is located above the humidifying mesh 2.

[0020] As can be seen from the above description, the beneficial effects of this utility model are as follows: The humidifier provided by this utility model uses a power source 5 to drive the bracket 3 and water pipe 4 to rotate, so as to send the water in the water tank 1 to the humidification net 2. The power source 5 and other electrical components and wires are located outside the water tank 1, so there is no risk of water ingress and short circuit.

[0021] In some embodiments, please refer to Figure 1 and Figure 2 The humidifying net 2 includes a water receiving tray 21, which is located on the upper side of the humidifying net 2. The water receiving tray 21 is evenly provided with a plurality of drainage holes 211.

[0022] As can be seen from the above description, the drainage holes 211 evenly arranged on the water receiving tray 21 can make the water injected into the water receiving tray 21 from the water outlet 42 of the water pipe 4 evenly replenish the humidifying net 2.

[0023] In some embodiments, please refer to Figure 1 and Figure 2 The water receiving tray 21 has a water receiving groove, and the drain hole 211 is located at the bottom of the water receiving groove.

[0024] As can be seen from the above description, the drain hole 211 is located at the bottom of the water receiving tank to prevent water from accumulating in the water receiving tank.

[0025] In some embodiments, please refer to Figure 1 The humidifier includes a fan wheel 6, below which is a negative pressure space located between the fan wheel 6 and the water tank 1, and a humidifying mesh 2 surrounding the negative pressure space.

[0026] As can be seen from the above description, when the impeller 6 rotates, a negative pressure is formed in the negative pressure space. The airflow passes through the humidifying net 2, the negative pressure space and the impeller 6 in sequence. The humidifying net 2 surrounds the negative pressure space, so that airflow from different directions can enter the negative pressure space through the humidifying net 2.

[0027] In some embodiments, please refer to Figure 1 The humidifier has an air inlet mesh 8 and an air outlet mesh 9. The air inlet mesh 8 is arranged around the humidifying mesh 2, and the air outlet mesh 9 is located above the impeller 6.

[0028] As can be seen from the above description, the air inlet mesh 8 surrounds the humidifying mesh 2, which helps to increase the air intake volume and shorten the distance between the air inlet mesh 8 and the humidifying mesh 2. The airflow experiences less resistance as it flows from the air inlet mesh 8 to the humidifying mesh 2.

[0029] In some embodiments, please refer to Figure 1 The humidifier includes a mounting bracket 7, a water outlet 42 located between the mounting bracket 7 and the humidifying net 2, and a power source 5 fixed on the upper side of the mounting bracket 7.

[0030] As can be seen from the above description, the mounting bracket 7 provides a mounting position for the power source 5 while separating the power source 5 from the water outlet pipe 4 and the humidifying net 2.

[0031] In some embodiments, please refer to Figure 3 and Figure 4 The power source 5 has screw holes, and the power source 5 is fixed to the mounting bracket 7 by screws passing through the screw holes.

[0032] As can be seen from the above description, the power source 5 is fixed to the mounting bracket 7 with screws, and the structure is simple.

[0033] In some embodiments, please refer to Figure 3 and Figure 4 The power source 5 is a motor with a power output shaft. The power output shaft passes through the mounting bracket 7 and is connected to the bracket 3 for transmission.

[0034] As can be seen from the above description, the power output shaft passes through the mounting bracket 7 and connects to the bracket 3, which solves the problem of how to connect the power source 5 and the bracket 3 when they are located on different sides of the mounting bracket 7.

[0035] In some embodiments, please refer to Figure 3 and Figure 4 A first gear 51 is fixed on the power output shaft. The first gear 51 is located below the mounting bracket 7. A second gear 31 is fixed on the upper end of the bracket 3. The second gear 31 meshes with the first gear 51.

[0036] As can be seen from the above description, the power output shaft and the bracket 3 are connected by gear transmission, and the structure is simple.

[0037] In some embodiments, the humidifier includes an upper limit bracket and a lower limit bracket. The upper end of the bracket 3 is provided with an upper limit groove corresponding to the upper limit bracket, and the lower end of the bracket 3 is provided with a lower limit groove corresponding to the lower limit bracket. The upper limit bracket and the lower limit bracket are respectively engaged in the upper limit groove and the lower limit groove to prevent the first gear 51 from separating from the second gear 31.

[0038] As can be seen from the above description, the bracket 3 is prevented from moving by the cooperation of the limiting frame and the limiting groove, thereby preventing the first gear 51 and the second gear 31 from separating. The structure is simple.

[0039] Please refer to Figures 1 to 5 One embodiment of this utility model is as follows: A type of humidifier, please refer to Figure 1 The humidifier includes a bracket 3, a water pipe 4, a fan 6, a power source 5, an air inlet screen 8, and, arranged sequentially from bottom to top along the height of the humidifier, a water tank 1, a humidifying screen 2, a mounting bracket 7, and an air outlet screen 9. The bracket 3 is inserted obliquely into the water tank 1, and the water pipe 4 is spirally wound and fixed to the bracket 3. The water pipe 4 has a water inlet 41 and a water outlet 42. The water inlet 41 is located inside the water tank 1, and the water outlet 42 is located between the mounting bracket 7 and the humidifying screen 2. The mounting bracket 7 is arranged around the fan 6. The inner diameter of the water pipe 4 is large enough that the possibility of clogging is extremely low.

[0040] Please refer to Figure 2 The humidifying net 2 includes a water receiving tray 21, which is located on the upper side of the humidifying net 2. The water receiving tray 21 is evenly provided with a plurality of drain holes 211. The water receiving tray 21 has a water receiving groove, and the drain holes 211 are located at the bottom of the water receiving groove.

[0041] Please refer to Figure 4 and Figure 5 The power source 5 is a motor, fixed to the upper side of the mounting bracket 7 with screws. The power source 5 has a power output shaft that passes through the mounting bracket 7. A first gear 51 is fixed on the power output shaft and is located below the mounting bracket 7. A second gear 31 is fixed to the upper end of the bracket 3, and the second gear 31 meshes with the first gear 51. The humidifier includes an upper limit bracket and a lower limit bracket. The upper limit bracket is located above the humidifying mesh 2. The upper end of the bracket 3 has an upper limit groove corresponding to the upper limit bracket. The lower limit bracket is located inside the water tank 1, and the lower end of the bracket 3 has a lower limit groove corresponding to the lower limit bracket. The upper and lower limit brackets are respectively engaged in the upper and lower limit grooves. Both the upper and lower limit brackets are two-part structures and are detachable, allowing users to easily remove the bracket 3 and water pipe 4. The water pipe 4 can be fixed to the bracket 3 with a cable tie for easy disassembly and cleaning.

[0042] Please refer to Figure 5The power source 5 is used to rotate the bracket 3. The water pipe 4 rotates with the bracket 3, thereby transporting water from the water tank 1 to the water receiving tray 21 based on the principle of an Archimedes' screw pump. The water in the water receiving tray 21 leaks into the humidifying net 2 through the drain hole 211. There is a negative pressure space below the impeller 6, which is located between the impeller 6 and the water tank 1. The humidifying net 2 is arranged around the negative pressure space, the air inlet net 8 is arranged around the humidifying net 2, and the air outlet net 9 is located above the impeller 6.

[0043] When the impeller 6 rotates, a negative pressure is formed in the negative pressure space. External air flows into the humidifier from the air inlet net 8, passes through the humidifying net 2, and the moisture in the humidifying net 2 is carried into the negative pressure space by the airflow. After passing through the impeller 6, it is discharged from the humidifier from the air outlet net 9.

[0044] In summary, the humidifier provided by this utility model uses a water pump based on the Archimedes' spiral pump principle. There are no electrically connected parts inside the water tank 1, resulting in a simple pump structure and high safety. Compared to conventional water pumps, it avoids the problem of easy clogging of the water circuit, is easier to disassemble and fix, and is also less expensive.
