[0022] The technical solutions in 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, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0023] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 1-6As shown, an intelligent household air purifying humidifier water level control device includes: an air purifying humidifier body 1, which has an impeller 104, a mixing chamber 105, and a filter element 106 inside; a water level control component located at the bottom of the air purifying humidifier body 1, which includes: an inner water tank 3, a spring 302, a guide rail 304, a side plate 5, a valve 501, a guide plate 502, a support plate 503, a through groove 504, a rocker arm 6, a slider 601, a pulley 602, and a connecting rod 603; and a water replenishment tank assembly located on one side of the air purifying humidifier body 1, which includes: an outer water tank 2, a bottom cover 201, a flow seat 202, a flow hole 203, a water channel 2031, a return spring 204, and a valve core 205.

[0025] The humidifier automatically replenishes water using a water level control component, requiring only maintenance of the external water tank 2, significantly reducing operation frequency. Furthermore, the elimination of electronic sensors within the water tank and the use of gravity-based mechanical control for water level control result in low standby power consumption and reduced susceptibility to water contamination. Secondly, the water replenishment component allows users to monitor the water level in the external water tank 2 during use, ensuring timely replenishment when the water runs out, preventing dry burning and guaranteeing the humidification effect of the air purifier.

[0026] The air purifying humidifier body 1 is surrounded by a grid 107 and has a motor 108 on top. The bottom of the air purifying humidifier body 1 is provided with a base plate 103, and the top of the base plate 103 is provided with an inner water tank 3. Four springs 302 are provided between the base plate 103 and the inner water tank 3. An atomizer 301 is provided inside the inner water tank 3. The atomizer 301 floats on the water surface and is fixedly connected to a lower fixing ring 303 on the outside. A membrane 305 is fixedly connected to the top of the lower fixing ring 303. An upper fixing ring 102 is fixedly connected to the top of the membrane 305. An air guide tube 101 is provided at the top of the upper fixing ring 102.

[0027] During the operation of the air purifying humidifier, the motor 108 starts and drives the impeller 104 to rotate, creating a negative pressure in the mixing chamber 105. As a result, external air passes through the grid 107 and filter element 106 and is purified before entering the air purifying humidifier body 1. At the same time, the atomizer 301 is powered on and consumes water in the inner water tank 3 to generate water vapor. The water level in the inner water tank 3 drops, causing the lower fixed ring 303 floating on the water surface to descend and drive the membrane 305 to extend. The lower fixed ring 303, membrane 305, upper fixed ring 102 and air guide pipe 101 are connected to form an air guide channel. Water vapor evaporates into the air guide channel. Due to the negative pressure in the mixing chamber 105, the purified air and water vapor are drawn into the mixing chamber 105. After mixing in the mixing chamber 105, the air is discharged from the top of the air purifying humidifier body 1, thereby achieving the purpose of air purification and humidification.

[0028] The inner water tank 3 has a side plate 5 on one side, a through groove 504 in the middle of the side plate 5, a diversion plate 505 on one side of the through groove 504, the diversion plate 505 is fixedly connected to the side plate 5, two guide plates 502 are symmetrically arranged inside the diversion plate 505, a valve 501 is slidably connected in the groove formed by the two guide plates 502, the valve 501 is slidably connected to the side plate 5, a connecting rod 603 is rotatably connected to the valve 501 near the top, sliders 601 are rotatably connected to both ends of the connecting rod 603, a rocker arm 6 is slidably connected inside the slider 601, a support plate 503 is rotatably connected to the middle of the rocker arm 6 via a rotating shaft, the support plate 503 is fixedly connected to the side plate 5, a pulley 602 is rotatably connected to one end of the rocker arm 6, a guide rail 304 is provided at the top and bottom of the pulley 602, the guide rail 304 is fixedly connected to the inner water tank 3, and the pulley 602 slides in the groove formed by the two guide rails 304.

[0029] When the atomizer 301 is powered on and consumes water from the inner water tank 3 to generate water vapor, the weight of the water in the inner water tank 3 decreases. The spring 302 overcomes the total weight of the inner water tank 3 and the water, pushing the inner water tank 3 upward. This causes the groove formed by the guide rail 304 to move upward, so that the pulley 602 slides in the groove and drives the front end of the rocker arm 6 to move upward. Since the rocker arm 6 has a fixed rotation fulcrum in the middle, the rear end of the rocker arm 6 moves downward. The slider 601 slides at the rear end of the rocker arm 6 and drives the connecting rod 603 to move downward. As a result, the connecting rod 603 drives the valve 501 to slide downward in the groove formed by the two guide plates 502. The water inlet formed by the valve 501 and the through groove 504 becomes larger, which increases the water flow into the inner water tank 3, thus realizing automatic water replenishment of the humidifier.

[0030] The air purifier humidifier body 1 has an external water tank 2 on one side of the channel 504, which is made of transparent material. A handle 206 is fixedly connected to one side of the external water tank 2, and a bottom cover 201 is fixedly connected to the bottom of the external water tank 2. The top of the drainage cavity 4 has a through hole, and the bottom cover 201 extends into the drainage cavity 4 through the through hole. A round hole is opened in the middle of the bottom cover 201. A drainage seat 202 is fixedly connected to the bottom of the drainage cavity 4. The top of the drainage seat 202 extends into the external water tank 2 through the round hole. Several water channels 2031 are opened on the outer side of the top of the drainage seat 202. A drainage hole 203 is opened on the top of the drainage seat 202. A valve core 205 is provided on the top of the drainage seat 202. A return spring 204 is fixedly connected between the valve core 205 and the bottom cover 201.

[0031] When the water in the outer water tank 2 is depleted, pull up the handle 206. The handle 206 moves the outer water tank 2 upward, causing the return spring 204 to contract under the action of elasticity. This causes the valve core 205 to be inserted into the round hole opened in the bottom cover 201. At the same time, the bottom of the valve core 205 separates from the top of the diversion seat 202, and the outer water tank 2 is removed. When installing the outer water tank 2, the bottom of the valve core 205 contacts the top of the diversion seat 202, causing the valve core 205 to move upward against the elasticity of the return spring 204. This causes the valve core 205 to separate from the bottom cover 201, allowing the water in the outer water tank 2 to enter the diversion chamber 4 through the water channel 2031 and the diversion hole 203. The water in the diversion chamber 4 enters the inner water tank 3 through the channel 401, the through groove 504, the valve 501, and the diversion plate 505 in sequence.

[0032] Working principle:

[0033] During the operation of the air purifying humidifier, the motor 108 starts and drives the impeller 104 to rotate, creating a negative pressure in the mixing chamber 105. As a result, external air passes through the grid 107 and filter element 106 and is purified before entering the air purifying humidifier body 1. At the same time, the atomizer 301 is powered on and consumes water in the inner water tank 3 to generate water vapor. The water level in the inner water tank 3 drops, causing the lower fixed ring 303 floating on the water surface to descend and drive the membrane 305 to extend. The lower fixed ring 303, membrane 305, upper fixed ring 102 and air guide pipe 101 are connected to form an air guide channel. Water vapor enters the air guide channel. Due to the negative pressure in the mixing chamber 105, the purified air and water vapor are drawn into the mixing chamber 105. After mixing in the mixing chamber 105, the air is discharged from the top of the air purifying humidifier body 1, thereby achieving the purpose of air purification and humidification.

[0034] The atomizer 301 is a 16mm 2.4MHz piezoelectric ceramic transducer atomizing plate. When the atomizer 301 is powered on and consumes water in the inner water tank 3 to generate water vapor, the weight of the water in the inner water tank 3 decreases. The spring 302 overcomes the total weight of the inner water tank 3 and the water and pushes the inner water tank 3 to move upward, causing the groove formed by the guide rail 304 to move upward. As a result, the pulley 602 slides in the groove and drives the front end of the rocker arm 6 to move upward. Since the rocker arm 6 has a fixed rotation fulcrum in the middle, the rear end of the rocker arm 6 moves downward. The slider 601 slides at the rear end of the rocker arm 6 and drives the connecting rod 603 to move downward. As a result, the connecting rod 603 drives the valve 501 to slide downward in the groove formed by the two guide plates 502, making the water inlet formed by the valve 501 and the through groove 504 larger, thus increasing the water flow into the inner water tank 3 and realizing automatic water replenishment of the humidifier.

[0035] When the water in the outer water tank 2 is depleted, pull up the handle 206. The handle 206 moves the outer water tank 2 upward, causing the return spring 204 to contract under the action of elasticity. This causes the valve core 205 to be inserted into the round hole in the bottom cover 201. At the same time, the bottom of the valve core 205 separates from the top of the diversion seat 202. When the outer water tank 2 is removed and installed, the bottom of the valve core 205 contacts the top of the diversion seat 202, causing the valve core 205 to move upward against the elasticity of the return spring 204. This causes the valve core 205 to separate from the bottom cover 201, allowing the water in the outer water tank 2 to enter the diversion chamber 4 through the water channel 2031 and the diversion hole 203. The water in the diversion chamber 4 then enters the inner water tank 3 through the channel 401, the through groove 504, the valve 501, and the diversion plate 505.
