Description

Technical Field

[0001] The invention relates to the field of humidification equipment, in particular to a high-efficiency and low-consumption air humidifier. Background Art

[0002] According to measurements, the most comfortable ambient temperature for humans is around 25°C, and the relative humidity is between 45% and 55%RH. Too low a relative humidity can cause dry skin and itching. Air humidifiers have a good effect on alleviating dry indoor air conditions, and can effectively increase air humidity and the comfort of living. Existing air humidifiers mainly use ultrasonic misting, which generates ultrasonic waves through physical high-frequency oscillations. Ultrasonic waves vibrate the water surface, throwing water off the water surface and breaking it into tiny particles to form water mist.

[0003] The existing humidifier includes a transparent water tank and a base supporting the water tank. The transparent water tank is fixedly mounted on the base. An atomizing assembly for atomizing the water tank is installed in the base. The water tank is equipped with a mist guide channel for guiding water mist. When the humidifier is working, the water in the water tank first flows to the atomizing assembly for atomization, and the atomized water mist is then discharged from the mist guide channel.

[0004] The existing humidifiers also have the following defects: 1) The water tanks of the existing humidifiers are all designed as vacuum structures. The vacuum structure can ensure that the water in the water tank will not leak out under the action of air pressure. In order to ensure the overall sealing, the water inlet and outlet of the water tank are shared, and the overall sealing is good. However, the disadvantage of this vacuum structure water tank is that it is not convenient to add water to the water tank. When adding water, you can only lift the water tank first, then turn the water tank over so that the bottom is facing up, and then add water from the bottom of the water tank. After the water is filled, turn it over and install it on the base. In this process, water will be more likely to spill out, and the operation is inconvenient, and there are certain safety hazards. 2) The blower has low blowing efficiency and blows directly to the atomization component through the ventilation duct. The ventilation and air guiding effect is not good, the wind flow is not smooth, and the wind speed is low, which affects the misting effect and atomization efficiency. In order to ensure sufficient blowing volume, a higher power blower is usually required, which not only increases the production cost, but also the high-power blower has a large noise and increases the product volume. 3) The water outlet of the water tank is controlled by a valve. The action of the valve is driven by a motor or electromagnetic switch, which consumes a lot of electricity. In addition, the water level detection mechanism installed in the water tank or the water storage chamber below the water tank also consumes additional electricity. 4) The overall structure is complex, the manufacturing cost is high, and the control through the electric control structure will increase the risk of failure. 5) The structural performance of the valve used for sealing is poor. The electromagnetic suction seal is not tight, and the sealing effect will be affected after a failure. Summary of the invention

[0005] The purpose of the present invention is to solve the above defects and provide a high-efficiency and low-consumption air humidifier, which is overall efficient and energy-saving, can increase the amount of mist output, improve the mist output effect, and has good sealing performance. The opening and closing of the water outlet can be automatically controlled without consuming electrical energy.

[0006] The object of the present invention is achieved in the following ways:

[0007] The high-efficiency and low-consumption air humidifier comprises a base and a water tank arranged on the base, a main control component is arranged inside the base, a top plate is arranged on the top of the base, the top plate is recessed inward to form an atomizing cavity for accommodating water, an oscillating plate for atomizing water is arranged in the atomizing cavity, a sealing bottom plate is arranged at the bottom of the water tank, the interior of the water tank is a accommodating cavity for containing water, a water outlet is arranged on the sealing bottom plate, the water contained in the water tank flows downwardly into the atomizing cavity along the water outlet, the upper end of the water tank has a water inlet communicated with the accommodating cavity, and the upper end of the water tank A detachable upper cover plate is provided for matching and covering the water inlet, the outer side wall of the water tank is recessed inward to form a mist outlet channel, the mist outlet channel extends upward from the bottom end of the water tank to the top end, the bottom end of the mist outlet channel is connected to the atomization chamber, and a detachable side cover plate is provided on the side of the water tank for matching and covering the mist outlet channel; a silicone valve for sealing and controlling the water outlet is installed on the inner side of the sealing bottom plate, the silicone valve includes an elastic connecting handle and a silicone sealing disk arranged at one end of the elastic connecting handle, and a downward protrusion and a silicone sealing disk are provided on the bottom surface of the silicone sealing disk. The sealing boss seals and blocks the water outlet. The sealing boss is always sealed and pressed against the water outlet by the downward elastic force of the elastic connecting handle. A lifting device that can be adjusted up and down is provided on the top plate. A top column extending upward to the water outlet is provided on the lifting device. When the top column is driven to the upper limit position by the lifting device, the top column will lift the silicone sealing disk upward along the water outlet to open the water outlet. The top surface of the top plate is concave downward to form a lower air duct connected to the atomizing chamber. The end of the lower air duct away from the atomizing chamber is the air outlet. The end of the air outlet away from the lower air duct is the air outlet. An air outlet is provided on the surface, and a blower controlled by a main control component is arranged inside the base. The wind blown by the blower is blown out along the air outlet, and the bottom surface of the sealed bottom plate is recessed upward to form an upper air duct corresponding to the position of the lower air duct. The lower air duct and the upper air duct are sealed and combined from below and above respectively to form an air guide cavity communicated with the atomization cavity. The cross-sectional area of ​​the air guide cavity gradually decreases from the end far away from the atomization cavity to the end close to the atomization cavity. When the blower is working, the wind blown out is blown toward the atomization cavity along the air guide cavity, and finally the mist in the atomization cavity is blown toward the mist outlet channel.

[0008] In the above description, as a preferred scheme, the air outlet protrudes upward along the top surface of the top plate and extends into the upper air duct, the end surface of the air outlet facing away from the lower air duct is an arc-shaped surface, and the air outlet holes are arranged at intervals on the arc-shaped surface of the air outlet, and the lower air duct gradually tilts downward from one end close to the air outlet along the end close to the atomization chamber to form an inclined surface, and the depth of the upper air duct gradually becomes shallower from one end farthest from the atomization chamber to the other end.

[0009] By adopting the above technical solution, the wind outlet head extends into the upper air duct, so that the wind blown out of the air outlet is blown out along the maximum stroke position of the air guide cavity to increase the wind pressure. The air outlet is set on the arc surface to avoid the wind blowing out from a single direction. The wind blown out from the arc surface covers a wider range. The lower air duct that is inclined downward to form an inclined surface will cause the wind to be blown into the atomization cavity downward. Since the direction of entry is downward, more mist will be driven by the airflow from bottom to top into the mist outlet channel to increase the amount of mist outlet and the mist outlet effect.

[0010] In the above description, as a preferred solution, the top of the side cover plate is provided with a plug-in piece extending inward and used to abut against the top of the water tank, the lower side of the plug-in piece is provided with a limiting protrusion extending downward, the top of the water tank is provided with a limiting groove for the limiting protrusion to be embedded, and both sides of the side cover plate are provided with inwardly protruding sealing ridges along the length extension direction thereof, and sealing grooves for the sealing ridges to be embedded are respectively provided on both sides of the mist outlet channel.

[0011] By adopting the above technical solution, when installing the side cover, the plug-in piece is inserted so that the limiting protrusion is embedded in the limiting groove, and after the upper cover is installed, it will abut against the upper side of the plug-in piece to form a fixing effect. In addition, during installation, the two sealing convex strips will be embedded in the sealing groove to seal both sides of the mist outlet channel, increasing the contact area between the side cover and the mist outlet channel, further improving the sealing and connection stability. At the same time, the sealing convex strip can be quickly embedded in the sealing groove, which is convenient for disassembly and assembly.

[0012] In the above description, as a preferred solution, a water baffle is provided at the bottom of the side cover plate for shielding the mist outlet channel, the water baffle extends inward to be close to the bottom of the mist outlet channel, and a hollow hole is left on the water baffle to facilitate the passage of mist, and a water guide portion extending downward is provided on the bottom surface of the water baffle.

[0013] By adopting the above technical scheme, the water retaining plate can block larger water droplets from directly splashing upward through the mist outlet channel, and prevent water droplets from remaining on the inner wall of the mist outlet channel. At the same time, the reserved hollow holes can ensure the atomization effect during mist outlet, and the water guide portion on the bottom surface of the water retaining plate extends downward to the water surface of the atomization chamber. During the operation of the air humidifier, a large number of larger water droplets will condense on the surface of the air duct cover and the mist outlet air duct. After the water droplets are formed, they will flow downward along the surface of the air duct cover and the mist outlet air duct. The water droplets first pass through the water retaining plate, and then flow downward along the water guide portion into the atomization chamber of the air humidifier. The water guide portion drains the water droplets, preventing the water droplets from dripping directly from the water retaining plate to the water surface of the atomization chamber, thereby preventing the sound of water droplets dripping, thereby improving the silent performance of the air humidifier when in use.

[0014] In the above description, as a preferred solution, the other end of the elastic connecting handle is a fixed part for matching and installing on the sealing bottom plate, the fixed part includes a flat plug-in block and a blocking block located at one end of the plug-in block close to the silicone sealing disk, and the thickness of the blocking block is greater than the thickness of the plug-in block, and the end face of the blocking block close to the plug-in block is used to form a limiting barrier, and the inner side surface of the sealing bottom plate is provided with a socket which protrudes upward and is convenient for inserting the plug-in block.

[0015] By adopting the above technical solution, the flat plug block is used for matching and inserting into the socket, and is designed as a quick-plug structure, which is convenient for quickly installing the elastic connecting handle on the socket, and also convenient for quickly completing disassembly and replacement. No tools are required for installing and replacing the elastic connecting handle. The blocking block can not only limit the position but also improve the stability of the installation to ensure that there will be no shaking after insertion.

[0016] In the above description, as a preferred scheme, a convex lens is sealed on the top plate, and a light source that irradiates light upward along the convex lens is provided below the convex lens, the light source is controlled by the main control component, a light-transmitting sheet is sealed on the sealed bottom plate, and the light-transmitting sheet is located directly above the convex lens, a light board is provided at the bottom of the upper cover plate, the light board is opposite to the light irradiated by the light source, so that the light irradiated by the light source is irradiated upward to the light board through the convex lens and the light-transmitting sheet respectively, the bottom surface of the light board is frosted to form a diffusion plate, and the outer side surface of the light board is smoothed to form a light guide strip.

[0017] By adopting the above technical solution, the convex lens and the light-transmitting sheet are both sealed to ensure that the top plate after the convex lens is installed and the bottom of the water tank after the light-transmitting sheet is installed have good sealing properties. On the one hand, it can ensure that the water tank will not leak water, and on the other hand, it can ensure that fog will not penetrate into the interior of the base, so as to prevent the main control components from being affected by fog and getting damp. In addition, the convex lens helps to collect the light irradiated upward by the light source. The collected light passes upward through the light-transmitting sheet and the water tank filled with water, and finally irradiates the light board, which can diffuse the light to the entire bottom of the light board. At the same time, part of the light can be directed to the outer side of the light board, and a light guide strip is formed for guiding light, so that the bottom surface of the entire light board and the outer side of the light board show the lighting effect, which increases the irradiation area of ​​the light source and the utilization rate of the light, so as to achieve the effect of atmosphere light as a whole. When the light irradiates the water tank, the water in the water tank can be illuminated brighter at the same time, which is not only convenient for people to check the amount of water in the water tank, but also can increase the overall lighting effect of the water tank under the refraction of water. Combined with the colorful light source, the whole humidifier can become dazzling and colorful, thereby enhancing the overall beauty of the humidifier.

[0018] In the above description, as a preferred solution, the top plate is made of plastic material, the convex lens and the top plate are sealed and fixed by secondary injection molding, the convex lens and the top plate are injection molded together as one piece through the injection molding process, and there is no connection gap between the convex lens and the top plate, which can ensure that fog will not penetrate into the interior of the base, and the main control component can be prevented from being affected by fog and getting damp, the sealed bottom plate is made of plastic material, the translucent sheet and the sealed bottom plate are sealed and fixed by secondary injection molding, and there is no connection gap between the translucent sheet and the sealed bottom plate, which can ensure that the water tank will not leak water.

[0019] In the above description, as a preferred solution, a mist outlet nozzle is left on the upper cover plate, and a conducting port connected to the mist outlet channel and the mist outlet nozzle is provided at one end of the light board close to the mist outlet channel, and a plug-in portion for mating and embedding into the inner edge of the water inlet is provided on the bottom surface of the light board.

[0020] By adopting the above technical solution, the mist in the mist outlet channel will be sprayed upward along the mist outlet nozzle through the guide port. When installing the cover plate, the plug-in part is embedded in the water inlet and pressed against the inner edge of the water inlet to fix it.

[0021] In the above description, as a preferred solution, the inner side surface of the conducting port near the inner end is provided with a limiting tongue extending downward to the top bottom surface of the mist outlet channel, the top bottom surface of the mist outlet channel is provided with a groove for the limiting tongue to be embedded, and the top of the side cover plate is provided with a resistance block extending upward into the conducting port and tightly against the inner side surface of the conducting port near the outer end.

[0022] By adopting the above technical solution, when installing the upper cover, the limiting tongue will be embedded into the top and bottom surfaces of the mist outlet channel to position the upper cover in the circumferential direction, and during installation, the abutment block will pass through the conducting port and abut against the inner side surface near the outer end, thereby reducing the possibility of the upper cover detaching from the mist outlet channel, thereby achieving a better connection effect.

[0023] In the above description, as a preferred solution, the lifting device is composed of a float arranged in the atomization chamber, one end of the float extends laterally outward to form a connecting rod, the top column is arranged at an end of the connecting rod away from the float and extends upward perpendicular to the connecting rod, and rotating shafts are arranged laterally and vertically on both sides of the connecting rod. A U-shaped groove for matching and embedding the rotating shaft is provided in the atomization chamber, and the float and the top column are lifted and lowered along the rotating shaft, so that the float and the top column are lifted and lowered alternately like a lever according to the rise and fall of the water level in the atomization chamber.

[0024] By adopting the above technical scheme, since the float and the top column are connected by a connecting rod, the float, the top column and the connecting rod are combined to form a lever mechanism. When the water in the atomization chamber is atomized by the atomizer and gradually exhausted, the float drops with the water level, and the top column will also move upward. During the rising process of the top column, it contacts the sealing boss. When the top column rises to the upper limit position, it pushes up the silicone sealing disk to make the water outlet conductive. At this time, the water in the water tank will flow into the atomization chamber along the outlet water. The water volume in the atomization chamber slowly increases, the float rises with the water level, and the top column drops accordingly. When the top column drops to be separated from the sealing boss, the elastic connecting handle rebounds to reset, and the sealing boss is pressed down by the elastic force to seal the water outlet. At this time, the atomization chamber is just filled, and the water level control is repeated until the water in the water tank is consumed.

[0025] In the above description, as a preferred solution, a speaker is also provided inside the base, and the speaker is controlled by a main control component.

[0026] By adopting the above technical solution, adding a speaker can increase the broadcasting and entertainment function of the air humidifier, and music can be played while humidifying the air, which increases the fun.

[0027] The beneficial effects produced by the present invention are as follows:

[0028] 1) The mist outlet channel is designed on the outer wall of the water tank to form a lateral mist outlet channel. In addition, it is also provided on a side cover plate that can be quickly disassembled. Compared with the traditional built-in mist outlet channel, the lateral mist outlet channel is easier to clean. During operation, the side cover plate can be directly disassembled to open the mist outlet channel and clean the mist outlet channel and the side cover plate. After removing the side cover plate, the opening of the mist outlet channel is made outward, which is more convenient to clean the dirt on the surface of the mist outlet channel and the side cover plate. At the same time, the upper cover plate can be quickly disassembled, and the inner wall of the water tank can be cleaned downward through the water inlet. When cleaning the water tank, it is not hindered by the mist outlet channel, which reduces the dirt caused by the humidification mist during the use of the water tank. The overall operation is convenient, no disassembly tools are required, and it is clean and hygienic when cleaning;

[0029] 2) The water inlet is set at the upper end of the water tank, and water can be added to the water tank by opening the upper cover. During operation, the upper cover can be directly opened to add water to the water tank, or the entire water tank can be directly lifted up to separate it from the base. Since a silicone valve for sealing and controlling the water outlet is set at the bottom of the water tank, and the sealing boss is always sealed against the water outlet by the downward elastic force of the elastic connecting handle, when the water tank is lifted, the water outlet is always in a sealed state, and no additional sealing operation is required. No electrical energy is required to control the seal, and the overall seal is good. No matter how the water tank is shaken, the water will not seep downward, so the water tank can be lifted to directly collect water, which is simple to operate and easy to use;

[0030] 3) Connect the silicone sealing disc through the elastic connecting handle to make the silicone sealing disc have good elasticity, ensure that the sealing boss is always sealed against the water outlet by the downward elastic force of the elastic connecting handle, and at the same time, the sealing boss surrounds and presses the water outlet, which comprehensively improves the sealing effect and makes it less likely for water to seep at the water outlet;

[0031] 4) The lifting device arranged in the base can intelligently adjust the water level of the atomizing chamber. Since the lifting device can be raised and lowered, when the water level in the atomizing chamber drops and the water volume is insufficient, the lifting device can be controlled to drive the top column to move upward, thereby lifting the silicone sealing disk upward, so that the water outlet is opened, and the water in the water tank flows downward into the atomizing chamber. When the water level in the atomizing chamber rises to a preset point, the lifting device drives the top column to move downward, thereby separating from the silicone sealing disk, and the elastic connecting handle rebounds to reset. The sealing boss is pressed down by the elastic force to seal the water outlet, and water is added to the atomizing chamber for intelligent adjustment to ensure that the air humidification works continuously and safely. The overall structure is simple, not easy to damage, has a long service life, and is low in cost. It does not require any electronic control equipment to achieve a good sealing effect. The opening and closing of the water outlet does not consume electricity, which saves electricity. It is convenient to seal the water outlet and to release the sealing state of the water outlet.

[0032] 5) The air guide cavity formed by the sealed combination of the lower air guide duct and the upper air guide duct is designed to be a gradually smaller structure. The wind blown by the blower will be blown out along the obliquely downward air guide cavity. Since the direction of the air guide cavity is downward and the air guide cavity gradually becomes smaller, the wind blown by the blower increases the overall wind pressure under the action of the air guide cavity. At the same time, the air outlet is arranged on the end face of the air outlet head away from the lower air guide duct, and the maximum stroke of the air guide cavity is used to increase the wind pressure. The mist generated when the oscillation plate is atomized will be blown into the atomization cavity by the wind from the oblique downward direction of the air guide cavity. Since the wind pressure blown out of the air guide cavity is relatively large, more mist will be driven by the airflow from bottom to top into the mist outlet channel. With the auxiliary action of the efficient and energy-saving blowing system, the overall mist output is increased, and the mist outlet effect of the air humidifier is improved. Only a low-power blower is needed to achieve efficient blowing, with low cost and low noise, so as to achieve the purpose of overall high efficiency and energy saving.

There is no connection gap between the light-transmitting sheet 303 and the sealed bottom plate 3, which can ensure that the water tank 4 will not leak water.

[0064] In addition, Figure 6-Figure 11 As shown, a mist outlet nozzle 601 is left on the upper cover plate 6, and a conducting port 503 communicating with the mist outlet channel 402 and the mist outlet nozzle 601 is provided at one end of the lamp board 5 close to the mist outlet channel 402, and a plug-in portion 504 for matching and embedding into the inner edge of the water inlet 401 is provided on the bottom surface of the lamp board 5. A limiting tongue 505 extending downward to the top bottom surface of the mist outlet channel 402 is provided on the inner side surface of the conducting port 503 near the inner end, and an embedding groove 407 for the limiting tongue 505 to be embedded is provided on the top bottom surface of the mist outlet channel 402, and a resisting block 408 extending upward into the conducting port 503 and close to the inner side surface of the conducting port 503 near the outer end is provided on the top of the side cover plate 403.

[0065] like Figure 19-Figure 24As shown, a silicone valve for sealing and controlling the water outlet 302 is installed on the inner side of the sealing bottom plate 3, and the silicone valve includes an elastic connecting handle 307 and a silicone sealing disk 308 arranged at one end of the elastic connecting handle 307, and a sealing boss 309 protruding downward and used for sealing and blocking the water outlet 302 is provided on the bottom surface of the silicone sealing disk 308, and one end of the elastic connecting handle 307 close to the silicone sealing disk 308 is arranged in an arc-shaped protrusion, and the elastic connecting handle 307 is composed of a flat spring piece and a silicone sheath wrapped around the outer periphery of the spring piece, and the spring piece is connected from the silicone sealing disk 308 to the outer periphery of the water outlet 302. The disk 308 extends from one end to the other end. A push rod 310 is longitudinally arranged inside the silicone sealing disk 308. The push rod 310 is located at the center of the sealing boss 309. The bottom of the push rod 310 extends downward and protrudes from the bottom surface of the sealing boss 309 to form a force contact. The force contact is used to match downward and block the water outlet 302. The force contact and the sealing boss 309 are always sealed against the water outlet 302 by the downward elastic force of the elastic connecting handle 307. The bottom edge of the silicone sealing disk 308 is provided with a sealing convex ring 311 that protrudes downward and is used for sealing. Fig.21 As shown, the top of the silicone sealing disk 308 is connected to the elastic connecting handle 307 via a deformable elastic neck 312, and the bottom surface of the silicone sealing disk 308 gradually slopes downward from one end close to the fixing portion to the other end. Fig. 20 As shown, the other end of the elastic connecting handle 307 is a fixing portion for matching and mounting on the sealing bottom plate 3, the fixing portion includes a flat plug block 313 and a blocking block 314 located at one end of the plug block 313 close to the silicone sealing disk 308, and the thickness of the blocking block 314 is greater than the thickness of the plug block 313, and one end surface of the blocking block 314 close to the plug block 313 is used to form a limiting barrier, and the inner side surface of the sealing bottom plate 3 is provided with a socket 306 which protrudes upward and is convenient for inserting the plug block 313.

[0066] The top plate 2 is provided with a lifting device that can be raised and lowered and adjusted. The lifting device is provided with a top column 211 extending upward to the water outlet 302. When the top column 211 is driven to the upper limit position by the lifting device, the top column 211 will lift the silicone sealing disk 308 upward along the water outlet 302 to open the water outlet 302. The lifting device of this embodiment is composed of a floating ball 209 arranged in the atomizing chamber 208, one end of the floating ball 209 extends outwardly horizontally to form a connecting rod 210, and a top column 211 is arranged at one end of the connecting rod 210 away from the floating ball 209 and extends upward perpendicularly to the connecting rod 210. The two side surfaces of the connecting rod 210 are provided with a rotating shaft 212 horizontally and vertically, and a U-shaped groove 213 for matching and embedding the rotating shaft 212 is provided in the atomizing chamber 208. The floating ball 209 and the top column 211 are lifted and lowered along the rotating shaft 212, so that the floating ball 209 and the top column 211 are lifted and lowered alternately like a lever according to the rise and fall of the water level in the atomizing chamber 208.

[0067] Since the float 209 and the top column 211 are connected by the connecting rod 210, the float 209, the top column 211 and the connecting rod 210 form a lever mechanism. When the water in the atomizing chamber 208 is atomized by the atomizer and gradually exhausted, the float 209 drops with the water level. Fig.23 As shown, the top column 211 will also move upward. During the upward movement of the top column 211, it will contact the force-bearing contact point. When the top column 211 rises to the upper limit position, it will lift the silicone sealing disk 308 upward to make the water outlet 302 conductive. At this time, the water in the water tank 4 will flow into the atomizing chamber 208 along the outlet water. The water volume in the atomizing chamber 208 will gradually increase, and the float 209 will rise with the water level. Fig.24 As shown, the top column 211 descends accordingly. When the top column 211 descends to the point where it is separated from the force-bearing contact, the elastic connecting handle 307 rebounds to reset, and the sealing boss 309 and the force-bearing contact are pressed downward by the elastic force to seal the water outlet 302. At this time, the atomizing chamber 208 is just filled up, and the water level control is repeated until the water in the water tank 4 is consumed.

[0068] In order to realize intelligent power-off control, a control switch for controlling the on-off of the power supply circuit is provided below the float 209. The control switch is composed of a Hall sensor. A triggering member for triggering the control switch is provided at one end of the float 209 away from the connecting rod 210. The triggering member is composed of a magnet block 214. The arrangement of the control switch and the triggering member enables the float 209 to move downward, drive the triggering member downward to approach and trigger the control switch, and the control switch can cut off the control power supply circuit of the entire air humidifier, so that the air humidifier stops working and the oscillating plate stops atomizing. The float 209 drops because the amount of water in the water storage chamber drops to almost nothing. Therefore, when the air humidifier stops working, idling will not occur, which better protects the air humidifier, improves the service life of the air humidifier, and reduces the consumption of electric energy.

[0069] like Figure 12-16As shown, the top surface of the top plate 2 is concave downward to form a lower air duct 202 that is connected to the atomizing chamber 208. The end of the lower air duct 202 away from the atomizing chamber 208 is an air outlet 203. The end surface of the air outlet 203 away from the lower air duct 202 is provided with an air outlet hole 204. The inside of the base 1 is provided with a blower 101 controlled by a main control component 102. The air blown by the blower 101 is blown out along the air outlet hole 204. The bottom surface of the base 1 is provided with an air inlet, and the bottom of the sealed bottom plate 3 is provided with an air inlet. The surface is recessed upward to form an upper air duct 304 corresponding to the position of the lower air duct 202. The lower air duct 202 and the upper air duct 304 are sealed and combined from the bottom and the top respectively to form an air guide cavity connected to the atomization chamber 208. The cross-sectional area of ​​the air guide cavity gradually decreases from the end far away from the atomization chamber 208 to the end close to the atomization chamber 208. When the blower 101 is working, the wind blown out along the air guide cavity is blown toward the atomization chamber 208, and finally the mist in the atomization chamber 208 is blown toward the mist outlet channel 402. The air outlet 203 protrudes upward along the top surface of the top plate 2 and extends into the upper air duct 304. The end surface of the air outlet 203 facing away from the lower air duct 202 is an arc-shaped surface. The air outlet holes 204 are arranged at intervals on the arc-shaped surface of the air outlet 203. The lower air duct 202 gradually tilts downward from one end close to the air outlet 203 to one end close to the atomizing chamber 208 to form an inclined surface. The depth of the upper air duct 304 gradually becomes shallower from one end away from the atomizing chamber 208 to the other end. The surfaces of the lower air duct 202 and the upper air duct 304 of this embodiment are both smooth surfaces. A plug-in slot is provided on the top plate 2 and located on the side of the air outlet 203 facing away from the lower air duct 202. The opening of the plug-in slot is upward, which is used for matching and inserting the scented sheet 205. The plug-in slot is provided to facilitate the removal and replacement of different scented sheets 205, including ordinary scented sheets 205 with fragrance or tablets with medicinal ingredients that can be disinfected and sterilized. The wind blown out from the air outlet 204, mixed with the fragrance of the scented sheets 205, is continuously blown to the atomization chamber 208. At this time, the mist is mixed with the fragrance and discharged along the mist outlet channel 402. When the fragrance needs to be changed, only the scented sheet 205 needs to be replaced. The operation is simple and easy to use.

[0070] The implementation principle of this embodiment is: first open the upper cover plate 6, fill a proper amount of water into the water tank 4 along the water filling port 401, and place the water tank 4 on the base 1 accordingly, so that the positioning column 201 is matched and inserted into the positioning groove 305. At this time, since there is no water in the atomization chamber 208, the float 209 drops to the lower limit position, and the top column 211 pushes the top rod 310 upward to open the water outlet 302. At this time, the water in the water tank 4 will flow into the atomization chamber 208 along the outlet water, and the water volume in the atomization chamber 208 will slowly increase. The float 209 rises with the water level, and the top column 211 drops accordingly. When the top column 211 drops to be separated from the force-bearing contact, the elastic connecting handle 307 rebounds to reset, and the sealing boss 309 and the force-bearing contact are pressed down by the elastic force to seal the water outlet 302. At this time, the water storage chamber is just filled. Then, the power is turned on, and the air humidifier is started through the control panel. The oscillating plate atomizes the water in the atomizing chamber 208 to generate mist in the atomizing chamber 208. At the same time, the blower 101 works, and the wind blown by the blower 101 will be blown out along the obliquely downward wind guide chamber. The mist generated when the oscillating plate atomizes will be blown into the atomizing chamber 208 by the wind from the obliquely downward direction of the wind guide chamber. Since the wind pressure blown out of the wind guide chamber is relatively large, more mist will be driven by the airflow from bottom to top into the mist outlet channel 402, and finally the mist will be discharged along the mist outlet channel 402 to the mist outlet nozzle 601. When the water in the water tank 4 is completely exhausted, the float 209 drops to the lower limit position, driving the trigger member to approach downward and trigger the control switch. The control switch can cut off the control power supply circuit of the entire air humidifier, and the air humidifier stops working. When the water tank 4 has been used for a long time, the upper cover plate 6 and the side cover plate 403 can be removed to open the mist outlet channel 402 , and then the mist outlet channel 402 and the water tank 4 can be cleaned, and the inner wall of the water tank 4 can be cleaned through the water inlet 401 . Before cleaning, the water tank 4 is first removed from the base 1. When the upper cover plate 6 is removed upwards, the plug-in part 504 is separated from the water inlet 401. At this time, the limiting tongue 505 is separated from the embedding groove 407, and the abutment block 408 is separated from the conducting port 503. When the side cover plate 403 is removed outward, the limiting protrusion 405 is separated from the limiting groove 406, and at the same time, the sealing ridge 409 is separated from the sealing groove 410. After removal, the mist outlet channel 402 can be cleaned, and the inner wall of the water tank 4 can be cleaned at the same time. Since the mist outlet channel 402 is on the outside of the water tank 4, it can be cleaned by hand or other cleaning tools. Compared with the existing humidifier, it is more convenient to clean, does not require any disassembly tools, and is clean and hygienic.
