If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0030] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0031] It is understandable that, referring to Figures 1 to 7The humidifier of the utility model includes a shell 100 and a humidifying assembly 200. The upper end of the shell 100 is provided with an air outlet 110, and the side wall of the shell 100 is provided with an air inlet 120; the humidifying assembly 200 includes a water tank 210, a water curtain 220, a PTC heating tube 230 and a fan 240. The water tank 210 is connected to the lower end of the shell 100, and the water curtain 220 is arranged in the inner cavity of the water tank 210. The water curtain 220 separates the water tank 210 into a first chamber 211 and a second chamber 212. A protective cover is arranged in the second chamber 212 270, the PTC heating tube 230 is located inside the protective cover 270, and the wall surface of the protective cover 270 is provided with a plurality of through holes 271 to connect with the second chamber 212. The fan 240 is arranged at the upper end of the water curtain 220, and the fan 240 includes an air guide cover 260, and the air guide cover 260 and the side wall of the shell 100 form an air inlet channel 130, and the interior of the air guide cover 260 forms an air outlet channel 140, the air inlet channel 130 connects the first chamber 211 and the air inlet 120, and the air outlet channel 140 connects the second chamber 212 and the air outlet 110.

[0032] Since the water curtain 220 is arranged in the inner cavity of the water tank 210, and the water curtain 220 divides the water tank 210 into a first chamber 211 and a second chamber 212, a protective cover 270 is arranged in the second chamber 212, and the PTC heating tube 230 is located inside the protective cover 270. The water temperature in the water tank 210 is increased by heating the PTC heating tube 230, thereby increasing the water temperature adsorbed on the water curtain 220. The fan 240 drives the air to enter from the air inlet 120 on the side wall of the housing 100, and the air inlet 120 is driven by the fan 240. The air flows through the air inlet channel 130, the first chamber 211, the second chamber 212 and the air outlet channel 140, and is blown out from the air outlet 110 at the upper end of the housing 100. When the air flows from the first chamber 211 into the second chamber 212, it needs to pass through the water curtain 220 to be humidified. By increasing the water temperature on the water curtain 220, the water evaporation rate is increased, thereby increasing the air humidification amount and humidification efficiency, and the water on both sides of the protective cover 270 can circulate and exchange heat through the through hole 271 to improve the heating efficiency. In addition, by blocking the PTC heating tube 230 inside the protective cover 270, direct contact between the PTC heating tube 230 and the water tank 210, and between the PTC heating tube 230 and the water curtain 220 can be avoided, thereby reducing the risk of the water tank 210 and the water curtain 220 being burned, and also preventing users from being scalded by direct contact with the PTC heating tube 230, so as to improve the safety of the humidifier.

[0033] Furthermore, by setting the water curtain 220 in the inner cavity of the water tank 210, when the PTC heating tube 230 heats the water in the water tank 210, the water curtain 220 is directly in contact with the water in the water tank 210 for heat conduction, so that the water curtain 220 is heated and heated, which can reduce the temperature drop rate of the water adsorbed on the water curtain 220, thereby improving the air humidification amount and humidification efficiency. In addition, by arranging the fan 240 at the upper end of the water curtain 220, it is possible to prevent the moisture accumulated on the water curtain 220 from flowing back from the top of the fan 240 to the water tank 210, thereby reducing the risk of damage to the fan 240.

[0034] It should be noted that the PTC heating tube 230 can heat the water temperature to 40° C.-50° C., which can increase the water evaporation rate.

[0035] The protective cover 270 can be made of ceramic or silicone, etc., which can provide heat resistance and heat insulation effects, thereby reducing the risk of burning the water tank 210 and the water curtain 220 when the protective cover 270 contacts the water tank 210 and the water curtain 220.

[0036] It is understandable that, referring to Figure 2 , Figure 3 , Figure 5 and Figure 6 The top of the protective cover 270 is connected to the air guide cover 260, the electrical connection end of the PTC heating tube 230 is fixedly connected to the top of the protective cover 270, the heating end of the PTC heating tube 230 extends toward the bottom wall of the water tank 210, and a gap is formed between the heating end of the PTC heating tube 230 and the protective cover 270. By fixing the electrical connection end of the PTC heating tube 230 to the top of the protective cover 270, the shaking of the PTC heating tube 230 caused by the impact of water flow can be reduced, so as to improve the positional stability of the PTC heating tube 230. At the same time, the risk of moisture wetting the electrical connection end of the PTC heating tube 230 can be reduced, so as to improve the safety of use. By extending the heating end of the PTC heating tube 230 toward the bottom wall of the water tank 210, the vertical water in the water tank 210 can be evenly heated to improve the heating efficiency. In addition, since a gap is formed between the heating end of the PTC heating tube 230 and the protective cover 270, direct heating of the protective cover 270 by the PTC heating tube 230 can be avoided, thereby avoiding the risk of damage to the contact part of the water tank 210 and the protective cover 270 due to heat, thereby extending the service life of the water tank 210.

[0037] It should be noted that a gap may also be formed between the protective cover 270 and the water curtain 220 to avoid the risk of damage to the contact portion of the water curtain 220 and the protective cover 270 due to heat, thereby extending the service life of the water curtain 220.

[0038] It is understandable that, referring to Figure 3 and Figure 6The air guide cover 260 is provided with a sleeve portion 263, and a connecting portion 273 is vertically protruded on the top of the protective cover 270. The sleeve portion 263 is sleeved on the connecting portion 273. The connecting portion 273 is provided with a mounting hole 272, and the electrical connection end of the PTC heating tube 230 is installed in the mounting hole 272. By plugging the connecting portion 273 into the sleeve portion 263, the installation and fixation of the protective cover 270 is facilitated, the position stability of the protective cover 270 can be improved, and the possibility of tilting and shaking of the protective cover 270 can be reduced. By installing the electrical connection end of the PTC heating tube 230 in the mounting hole 272, the PTC heating tube 230 can be conveniently fixed on the protective cover 270, thereby improving the assembly efficiency. The PTC heating tube 230 is limited and fixed by the mounting hole 272, and the position stability of the PTC heating tube 230 can be improved.

[0039] It should be noted that the connecting portion 273 is circular, and the shape of the sleeve portion 263 matches the shape of the connecting portion 273 , so that the connecting portion 273 can be inserted and fixed in the sleeve portion 263 .

[0040] It is understandable that, referring to Figure 2 and Figure 7 The bottom wall of the water tank 210 is protrudingly provided with a plurality of first positioning blocks 213, which are evenly arranged at intervals along the circumference of the water tank 210, and the first positioning blocks 213 can abut against the outer wall of the protective cover 270 to locate the position of the protective cover 270. Since the plurality of first positioning blocks 213 are evenly arranged at intervals along the circumference of the water tank 210, the first positioning blocks 213 abut against the outer wall of the protective cover 270 to locate the position of the protective cover 270, so that the outer wall of the protective cover 270 is subjected to balanced force along the circumferential direction, and the shaking of the protective cover 270 caused by the impact of water flow and air flow can be reduced, thereby improving the position stability of the protective cover 270.

[0041] It is understandable that, referring to Figure 2 and Figure 7 The bottom wall of the water tank 210 is protrudingly provided with a plurality of second positioning blocks 214, which are evenly arranged at intervals along the circumference of the water tank 210, and the second positioning blocks 214 can abut against the inner wall of the water curtain 220 to locate the position of the water curtain 220. Since the plurality of second positioning blocks 214 are evenly arranged at intervals along the circumference of the water tank 210, the second positioning blocks 214 abut against the inner wall of the water curtain 220 to locate the position of the water curtain 220, so that the inner wall of the water curtain 220 is subjected to balanced force along the circumferential direction, the shaking of the water curtain 220 caused by the impact of water flow and air flow can be reduced, thereby improving the position stability of the water curtain 220.

[0042] It is understandable that, referring to Figures 2 to 4The opening of the water tank 210 is connected with a bracket 250, and the bracket 250 is provided with an annular protrusion 251 protruding toward the first chamber 211, and the top wall and side wall of the annular protrusion 251 are provided with a plurality of air inlet holes 252, and the air inlet channel 130 is connected with the first chamber 211 through the air inlet holes 252. The bracket 250 is provided with an annular protrusion 251 protruding toward the first chamber 211, and the top wall and side wall of the annular protrusion 251 are provided with a plurality of air inlet holes 252, so that the air in the air inlet channel 130 can enter the first chamber 211 through the air inlet holes 252, which can increase the air flow rate, thereby increasing the air humidification rate, and by arranging the air inlet holes 252 on the top wall and side wall of the annular protrusion 251, the annular protrusion 251 is subjected to a dispersed force in the circumferential direction, which can reduce the risk of deformation of the annular protrusion 251 due to airflow impact, thereby increasing the service life of the bracket 250.

[0043] Specifically, refer to Figure 2 , Figure 3 and Figure 5 The air guide cover 260 is provided with a circular protrusion 261 protruding toward the second chamber 212, and the top wall and side wall of the circular protrusion 261 are provided with a plurality of air outlet holes 262, and the air outlet channel 140 is connected to the second chamber 212 through the air outlet holes 262. The air guide cover 260 is provided with a circular protrusion 261 protruding toward the second chamber 212, and the top wall and side wall of the circular protrusion 261 are provided with a plurality of air outlet holes 262, so that the air in the second chamber 212 can enter the air outlet channel 140 through the air outlet holes 262, which can increase the air flow rate, thereby increasing the air humidification rate, and by arranging the air outlet holes 262 on the top wall and side wall of the circular protrusion 261, the circular protrusion 261 is subjected to a dispersed force in the circumferential direction, which can reduce the risk of deformation of the circular protrusion 261 due to airflow impact, thereby increasing the service life of the air guide cover 260.

[0044] Specifically, refer to Figures 2 to 5 , multiple air outlet holes 262 are evenly arranged at intervals along the circumference of the circular protrusion 261, and multiple air inlet holes 252 are evenly arranged at intervals along the circumference of the annular protrusion 251. By evenly arranging multiple air inlet holes 252 at intervals along the circumference of the annular protrusion 251, air can be uniformly transported from the air inlet channel 130 to the first chamber 211 along the circumference of the annular protrusion 251, so that air can evenly pass through the water curtain 220 along the circumference of the water curtain 220 to be humidified, so as to improve the air humidification uniformity and humidification efficiency, and by evenly arranging multiple air outlet holes 262 at intervals along the circumference of the circular protrusion 261, the humidified air can be evenly transported from the second chamber 212 to the air outlet channel 140 along the circumference of the circular protrusion 261, so as to improve the air supply uniformity.

[0045] Specifically, refer to Figure 2 and Figure 3 The annular protrusion 251 is arranged around the circular protrusion 261, and an annular groove 253 is formed between the annular protrusion 251 and the circular protrusion 261, and the upper end of the water curtain 220 is clamped in the annular groove 253. By clamping the upper end of the water curtain 220 in the annular groove 253, the water curtain 220 can be limited to reduce the shaking of the water curtain 220 caused by the impact of water flow and air flow, thereby improving the position stability of the water curtain 220 and facilitating the disassembly and cleaning of the water curtain 220.

[0046] It should be noted that a circular hole is opened in the middle of the bracket 250 , and the circular protrusion 261 can pass through the circular hole to extend into the interior of the water tank 210 .

[0047] It is understandable that, referring to Figure 2 and Figure 3 The humidification component 200 also includes a temperature sensor 280, a liquid level sensor 290 and a controller. The temperature sensor 280 and the liquid level sensor 290 are both located inside the protective cover 270, and the temperature sensor 280 and the liquid level sensor 290 are both electrically connected to the controller. The temperature sensor 280 detects the water temperature in the water tank 210, and feeds back the temperature information to the controller. The controller controls the PTC heating tube 230 to heat the water temperature to a preset value, thereby reducing the risk of excessive water temperature. The liquid level sensor 290 detects the water level in the water tank 210, and feeds back the water level information to the controller. When the water level is lower than the preset value, the controller controls the PTC heating tube 230 to stop heating, thereby reducing the risk of dry burning, thereby improving the safety of the humidifier. In addition, since the temperature sensor 280 and the liquid level sensor 290 are both located inside the protective cover 270, the protective cover 270 blocks foreign particles from entering the interior of the protective cover 270, thereby reducing the risk of sensor failure caused by foreign particles adhering to the sensing parts of the temperature sensor 280 and the liquid level sensor 290, thereby improving the safety of the humidifier.
