Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air purification and humidification, and in particular to a purification humidifier. BACKGROUND

[0002] At present, the mainstream humidifiers on the market generally adopt the evaporation type humidification principle, that is, through the built-in fan to drive the airflow to pass through the pre-wet filter screen, the contact of the airflow and the wet filter screen is used to make the water on the filter screen evaporate naturally and blend into the airflow, so as to finally realize the air humidification effect. In order to maintain the continuous wet state of the filter screen, some products use the water absorption of the filter screen itself to supply water by siphon, that is, the water in the water tank is adsorbed to the filter screen as a whole by the capillary action of the filter screen material, so as to complete the automatic wetting of the filter screen.

[0003] But this siphon water supply structure, when in use, the water level in the water tank will gradually decrease with the continuous consumption of the humidification process, resulting in the change of the contact depth of the filter screen and the water surface, and then causing the uneven water absorption of different areas of the filter screen, the local over-wetting and local dryness, so that when the airflow flows through the filter screen, the contact with the effective wet area is insufficient and the contact area is unstable, finally resulting in the unstable humidification amount of the humidifier, affecting the humidification efficiency of the equipment.

[0023] The technical solutions of the present application will be further described below in conjunction with the embodiments and the accompanying drawings.

[0024] Referring to Figures 1 to 9 The present application discloses a purifying humidifier, comprising a body 10, a humidifying part 20 and a flow guide assembly 40. The body 10 is provided with a humidifying cavity 101, a flow guide cavity 102, an air inlet 103, an air outlet 104 and a isolation cover 11. The isolation cover 11 is connected below the flow guide cavity 102 and above the humidifying cavity 101. The flow guide cavity 102 is in communication with the humidifying cavity 101, and the air outlet 104 is in communication with the other end of the flow guide cavity 102 away from the humidifying cavity 101.

[0025] In addition, the humidifying part 20 is installed in the humidifying cavity 101, and a humidifying space 201 is arranged inside the humidifying part 20. The humidifying part 20 comprises a water absorbing section 221 and a humidifying section 222. The humidifying section 222 and the water absorbing section 221 are distributed above and below along the axial direction of the humidifying part 20. The water absorbing section 221 is used to guide the water flow to the humidifying section 222. The isolation cover 11 surrounds the humidifying section 222 and is spaced from the water absorbing section 221 to form an air inlet interval 105. The air inlet interval 105 is in communication with the air inlet 103 and the humidifying space 201. The flow guide assembly 40 is arranged in the flow guide cavity 102. When the flow guide assembly 40 is started, it can guide the airflow to flow to the air inlet 103. After being introduced through the air inlet 103, the airflow successively flows through the air inlet interval 105, the humidifying part 20, the humidifying space 201 and the flow guide cavity 102, and finally is introduced to the external environment through the air outlet 104.

[0026] On the basis of the above structure, taking the water absorption section 221 of the humidifying piece 20 as the section immersed in the water body in the humidifying cavity 101 and the humidifying section 222 as the section exposed to the water surface as an example: when the humidifying piece 20 is assembled to the humidifying cavity 101, the water absorption section 221 continuously absorbs water from the humidifying cavity 101 by means of the capillary action and adsorption performance of the material itself, and stably delivers the absorbed water to the humidifying section 222 exposed to the water surface through the water transmission action inside the material, so that the humidifying section 222 maintains a continuous wet state.

[0027] Thereafter, the isolation cover 11 is correspondingly arranged on the outer periphery of the humidifying section 222, and the bottom of the isolation cover 11 is spaced apart from the upper part of the water absorption section 221 to form the air inlet interval 105. Since the air inlet interval 105 is adjacent to the water absorption section 221, and the water absorption section 221 is the water source of the humidifying section 222, the water content of the humidifying section 222 corresponding to the area of the air inlet interval 105 is the most sufficient, and the area of the air inlet interval 105 corresponding to the humidifying section 222 is the area with the largest effective wet area and the most uniform humidity in the humidifying section 222.

[0028] At the same time, the size of the air inlet interval 105 can be reasonably designed in combination with the water transmission range of the humidifying piece 20 and the lowest water level threshold of the humidifying cavity 101, so that even if the water level of the humidifying cavity 101 decreases to the lowest water level due to continuous consumption during the humidifying process, the area of the humidifying piece 20 corresponding to the air inlet interval 105 can still stably maintain the largest effective wet area, reducing the problem of reduced wet area and sudden decrease of humidifying amount caused by water level fluctuation.

[0029] When the device is running, the airflow is guided by the flow guide assembly 40 to be introduced from the air inlet 103. At this time, since the isolation cover 11 is arranged on the outer periphery of the humidifying section 222, the airflow above the humidifying piece 20 is effectively blocked, so that the airflow can only flow to the humidifying space 201 inside the humidifying piece 20 along the air inlet interval 105 between the bottom of the isolation cover 11 and the water absorption section 221. In this way, the airflow must pass through the area with the largest effective wet area above the water absorption section 221 to enter the humidifying space 201. In this process, the airflow is in full contact with the water in the largest wet area of the humidifying piece 20, so that the airflow can fully absorb the water, thereby achieving effective humidification of the airflow, so as to improve the humidity of the airflow finally guided out of the air outlet 104, thereby reducing the problem of unstable humidification amount and improving the humidification efficiency of the entire device.

[0030] In addition, the humidifying cavity 101 in the embodiment can adopt a separate shell or box with a hollow structure assembled at the bottom of the body 10 to form a separate humidifying cavity 101; or can be directly integrally formed with a hollow cavity in the body 10, so that the body 10 itself has the humidifying cavity 101. The flow guide cavity 102 is correspondingly arranged above the body 10 and also has a hollow structure design, so that a flow guide channel is formed above the body 10. When the body 10 is assembled, the humidifying cavity 101, the humidifying space 201 (the inner side of the humidifying piece 20), and the flow guide cavity 102 are distributed from bottom to top in the body 10.

[0031] When the device is running, the air flow can be introduced into the body 10 through the air inlet 103 under the action of the flow guide assembly 40, enter the humidifying space 201 from the air inlet interval 105 at the bottom of the isolation cover 11, and continue to flow from bottom to top to the flow guide cavity 102 above after being fully contacted with the humidifying piece 20 and humidified. Finally, the air flow is guided out through the air outlet 104. In this process, since the air flow flows from bottom to top, the small particles (such as dust, impurities, etc.) carried in the air flow will naturally precipitate under the action of their own gravity. The precipitated particles can be absorbed by the water body at the bottom of the humidifying cavity 101 or remain in the cavity, so that the discharged air flow is both humidified and purified by sinking, thereby improving the indoor air quality.

[0032] It should be noted that the humidifying piece 20 in the embodiment can directly adopt an existing air humidifying structure, such as a porous honeycomb humidifying net. The humidifying net can effectively increase the water-air contact area through a special porous honeycomb structure design, and can realize the improvement of air humidity by means of the uniform distribution and rapid evaporation of water on the surface of the porous structure.

[0033] Of course, the humidifying net can also select a sponge porous humidifying piece 20, such as a high-elasticity and high-water-absorption sponge (such as a polyurethane sponge). The internal rich interconnected pores can store a large amount of water, and can quickly soak when in contact with water flow, adapt to the humidification demand under different water levels, and also can realize the humidification of air humidity.

[0034] More specifically, the isolation cover 11 in the embodiment can adopt a hollow cover or shell structure. When assembled, the body 10 can be integrally formed in a connection mode, or can be separately processed by mechanical cutting, injection molding, etc., and then assembled in the body 10 by means of buckling, bolts, etc. in a detachable manner. The specific setting can be based on actual needs.

[0035] In addition, the flow guide assembly 40 can be selected from existing small axial flow fans, centrifugal fans or cross flow fans, etc. The flow guide assembly 40 can be installed on the upper part of the flow guide cavity 102 (close to the inner side of the air outlet 104) by using buckles, bolts or other connecting components, and the air outlet 104 is aligned with the inlet of the flow guide cavity 102 to guide the airflow.

[0036] Further, the purification humidifier includes a filter 50 which is detachably installed in the body 10. The filter 50 is located inside the air inlet 103 and is spaced apart from the outside of the humidifying element 20.

[0037] Based on the above structure, by arranging the filter 50 inside the air inlet 103, the airflow is first filtered by the filter 50 when it is introduced through the air inlet 103, and then flows to the air inlet spacing 105 and is introduced into the humidifying space 201. Subsequently, the airflow continues to flow from bottom to top to the flow guide cavity 102 and the air outlet 104, and is purified again during the process of flowing from bottom to top, so that the finally discharged airflow is double filtered, and the purification effect is better.

[0038] In addition, the filter 50 is spaced apart from the outside of the humidifying element 20, and a separate airflow channel is formed by reserving a reasonable spacing to reduce the adhesion of the humidifying element 20 to the surface of the filter 50 due to continuous humidification, or to reduce the blockage of the pores of the filter 50 after absorbing moisture, thereby reducing the airflow obstruction. The filtered airflow can flow smoothly to the air inlet spacing 105 along the spacing channel.

[0039] It should be noted that the filter 50 described above can directly use the air filtration structure in the related art, such as: primary filter screen (e.g. nylon screen), HEPA filter screen and activated carbon substrate filter screen. The primary filter screen, HEPA filter screen and activated carbon substrate filter screen are all porous honeycomb structures, so that the air can be purified by the filter 50.

[0040] In particular, the filter can be detachably connected to the body 10 by using buckles, screws, bolts or other connecting components, and is wrapped on the inner side of the air inlet 103, so that the filter 50 can be detached. In this way, the user can regularly take out the filter 50 for cleaning or replacement without disassembling the entire body 10, which is simple to operate.

[0041] Further, the humidifying member 20 comprises a filter frame 21 and a humidifying filter 22, the humidifying filter 22 is surrounded by the filter frame 21, a humidifying space 201 is formed inside the filter frame 21, and the water absorbing section 221 and the humidifying section 222 are formed on the humidifying filter 22, the water absorbing section 221 is connected to the bottom end of the humidifying section 222 and is used to guide the water flow to the humidifying section 222. Meanwhile, a buoyancy member 30 is arranged in the humidifying cavity 101, the buoyancy member 30 is surrounded above the water absorbing section 221 and is used to drive the humidifying member 20 to move along the axial direction of the humidifying member 20 when floating.

[0042] Specifically, during assembly, the filter frame 21 is used as the installation base, the humidifying filter 22 is surrounded by the filter frame 21, and the filter frame 21 provides stable support for the humidifying filter 22. Then, the buoyancy member 30 (such as existing foamed plastic, hollow floating ball, etc.) is connected to the humidifying filter 22 or the filter frame 21 in a detachable (such as clamping or threaded connection, etc.) or fixed manner, so that the buoyancy member 30 is surrounded above the water absorbing section 221, and through reasonable design, the contact area of the water absorbing section 221 with the water body is not blocked, the water transmission through the water absorbing section 221 is not hindered, and the water absorbing effect of the humidifying filter 22 is not affected.

[0043] After assembly, the buoyancy of the buoyancy member 30 can make the entire humidifying member 20 float on the water surface of the humidifying cavity 101. When the water level inside the humidifying cavity 101 decreases due to the humidifying process, the buoyancy member 30 will float downward along the axial direction of the humidifying member 20 (i.e. the vertical direction of the machine body 10) synchronously with the water level, and drive the entire humidifying member 20 to move downward synchronously through linkage; conversely, if the water level rises, the buoyancy member 30 drives the humidifying member 20 to move upward, so that the water absorbing section 221 always maintains a stable effective contact depth with the water body, reduces the water absorption deficiency caused by water level fluctuation, and the humidifying section 222 also adjusts the position as a whole with the humidifying member 20, so that the humidifying area corresponding to the air inlet interval 105 can always maintain the maximum effective humidifying area, and the phenomenon of unstable humidifying amount caused by water level decrease is reduced.

[0044] It should be noted that the distance between the air inlet interval 105 between the bottom of the isolation cover 11 and the water absorbing section 221 can be combined with the water transmission range of the humidifying member 20 and the floating stroke of the humidifying member 20 driven by the buoyancy member 30 in the early stage, so that the buoyancy member 30 drives the humidifying member 20 to descend to the lowest water level of the humidifying cavity 101, and the area of the humidifying filter 22 corresponding to the air inlet interval 105 can still maintain the maximum effective humidifying area. In this way, no matter whether the water level of the humidifying cavity 101 is at the highest position or the lowest position, the airflow flowing through the humidifying filter 22 through the air inlet interval 105 can fully contact the maximum effective humidifying area of the humidifying filter 22, improve the contact efficiency of the airflow and the water, and further continuously improve the humidifying efficiency of the equipment.

[0045] More specifically, the filter net frame 21 in the embodiment adopts a net frame structure, referring to Figure 7 Through the multiple mesh holes in the circumferential direction of the filter net frame 21, the water flow can uniformly flow to the humidifying filter screen 22, so that the humidifying filter screen 22 can fully contact the moisture after installation, and the humidifying effect is uniform.

[0046] In addition, after the humidifying filter screen 22 is assembled with the filter net frame 21, the outer peripheral wall of the humidifying filter screen 22 can be arranged in a gap fit with the inner wall of the isolation cover 11 to form a sliding fit. When the isolation cover 11 is covered above the humidifying filter screen 22, the humidifying piece 20 can be driven by the buoyancy piece 30 to smoothly slide along the inner wall of the isolation cover 11 in the axial direction of the isolation cover 11 (i.e. the vertical direction of the machine body 10), to guide the up and down floating of the humidifying piece 20 along the axial direction of the isolation cover 11, and the stroke is controllable.

[0047] At the same time, through the close-fit gap fit between the inner wall of the isolation cover 11 and the outer peripheral wall of the humidifying filter screen 22, the displacement of the humidifying piece 20 in the horizontal direction can also be limited, effectively reducing the left and right deviation and shaking of the entire humidifying piece 20 due to water level changes, airflow impact or slight shaking of the equipment, thereby reducing the size fluctuation of the air inlet interval 105 caused by the shaking of the humidifying piece 20, and further reducing the probability of insufficient contact and unstable contact area between the airflow and the humidifying filter screen 22 at the humidifying filter screen 22 of the air inlet interval 105, so that the airflow can stably contact the maximum effective wetting area of the humidifying filter screen 22, and the humidifying efficiency is further improved.

[0048] It should be noted that the gap between the isolation cover 11 and the humidifying filter screen 22 can be designed according to actual needs, which not only satisfies the smoothness of the axial sliding of the humidifying piece 20, but also realizes reliable radial limiting through the smallest gap, while avoiding jamming or wear caused by excessive friction between the two.

[0049] Further, the filter net frame 21 is provided with a first positioning frame 23 and a second positioning frame 24. The first positioning frame 23 is detachably connected to the top end of the humidifying filter screen 22, and the second positioning frame 24 is arranged at the bottom end of the filter net frame 21. The second positioning frame 24 is provided with a positioning groove 241 extending along the circumference of the filter net frame 21. The water absorption section 221 is installed in the positioning groove 241, and the buoyancy piece 30 is arranged above the positioning groove 241.

[0050] On the basis of this structure, referring to Figures 7 to 9 By arranging the positioning groove 241 at the bottom of the filter net frame 21 to install the water absorption section 221, and arranging multiple mesh holes in the circumference of the positioning groove 241, when the water absorption section 221 is embedded in the positioning groove 241, the water in the humidifying cavity 101 can smoothly enter the inside of the positioning groove 241 through these mesh holes, and fully contact the water absorption section 221, so as to ensure that the water absorption function of the water absorption section 221 is not affected by the installation structure, and the moisture can be continuously and stably conducted to the humidifying section 222.

[0051] At the same time, when the water absorption section 221 is installed, the groove wall of the positioning groove 241 can limit the water absorption section 221 in the radial direction, thereby limiting the displacement of the entire humidifying filter screen 22 in the horizontal direction, effectively reducing the shaking of the humidifying member 20 caused by airflow impact and water level fluctuation during use, so that the position of the humidifying filter screen 22 and the air inlet spacing 105 is relatively stable.

[0052] When the water absorption section 221 is installed, the humidifying section 222 above it is surrounded along the outer peripheral surface of the filter screen frame 21. At this time, the buoyant member 30 can be fixed to the upper end surface of the positioning groove 241 by connecting members (such as buckles, bolts) or gluing, etc., so that it is annularly surrounded outside the water absorption section 221, so that the buoyant member 30 can drive the entire humidifying member 20 to float up and down synchronously. Moreover, because the buoyant member 30 avoids the mesh area of the positioning groove 241, it will not block the water flow channel, so the installation of the buoyant member 30 will not interfere with the water absorption function of the water absorption section 221.

[0053] More specifically, when the humidifying filter screen 22, the buoyant member 30 and the second positioning frame 24 are assembled, the first positioning frame 23 can be connected to the top end of the humidifying filter screen 22 by buckle clamping, screw thread connection or other detachable methods, and the top end of the humidifying filter screen 22 is limited, combined with the limiting effect of the second positioning frame 24 at the bottom of the humidifying filter screen 22, to realize the fixation of the humidifying filter screen 22 in the vertical direction, reduce the probability of up and down movement of the humidifying filter screen 22, make the overall installation of the humidifying filter screen 22 more stable, and improve the stability of the humidifying effect.

[0054] Further, in the first positioning frame 23 of the embodiment, a connecting edge 231 is further provided at the edge of the first positioning frame 23. One end of the connecting edge 231 is connected to the top end of the first positioning frame 23, and the other end of the connecting edge 231 is arranged in a spaced manner with the outer peripheral wall of the first positioning frame 23, and the connecting edge 231 abuts against the inner wall of the isolation cover 11 and guides the sliding cooperation between the humidifying member 20 and the isolation cover 11 when the buoyant member 30 floats.

[0055] On the basis of this structure, during assembly, referring to Figure 7 The connecting edge 231 is arranged along the circumference of the first positioning frame 23, and the connecting edge 231 increases the contact and guiding area of the humidifying member 20 and the isolation cover 11, compared with the mode of cooperation between the humidifying filter screen 22 and the isolation cover 11, which can more accurately guide the movement of the humidifying member 20 along the isolation cover 11 in the axial direction (vertical direction), and reduce the phenomenon of jamming and deviation during floating.

[0056] In addition, since the other end of the connecting edge 231 is spaced apart from the outer peripheral wall of the first positioning frame 23, the space forms an elastic deformation space. When the connecting edge 231 is in contact with the inner wall of the isolation cover 11 and is subjected to radial pressure, the space can accommodate slight elastic deformation of the connecting edge 231, which not only reduces the sliding jamming of the humidifying element 20 caused by too tight fitting, but also compensates for the slight error of the fitting gap through deformation, so that the connecting edge 231 is effectively fitted with the inner wall of the isolation cover 11, and the friction loss between the connecting edge 231 and the isolation cover 11 is reduced, thereby indirectly prolonging the service life of the two.

[0057] More specifically, the connecting edge 231 is provided with a guide surface 232, which can be an inclined surface or an arc surface. When the connecting edge 231 is subjected to force, the guide surface 232 guides the sliding fitting of the connecting edge 231 with the inner wall of the isolation cover 11. When the humidifying element 20 floats up and down with the buoyant element 30, the connecting edge 231 and the inner wall of the isolation cover 11 slide relative to each other. If the guide surface 232 is an inclined surface, the inclined surface of the guide surface 232 converts surface contact into line contact through its own inclination during sliding, which reduces the friction area and disperses the radial pressure, thereby reducing the risk of jamming. If the guide surface 232 is an arc surface, the arc surface realizes smooth transition of the connecting edge 231 and the isolation cover 11 during sliding, thereby reducing the risk of jamming during the sliding fitting of the two.

[0058] Further, the humidifying element 20 is provided with a position element 60, and the machine body 10 is provided with a position detector 61 for detecting the position of the position element 60.

[0059] On the basis of this structure, by providing the position element 60 on the humidifying element 20, when the water level in the humidifying cavity 101 changes, the buoyant element 30 drives the humidifying element 20 to float up and down, and the position element 60 synchronously axially displaces with the humidifying element 20. Since the position detector 61 is installed on the machine body 10 corresponding to the position, the displacement signal of the position element 60 can be captured in real time by the position detector 61, and the position signal is transmitted to the background control panel and fed back to the user, so that the user can master the water level state in the humidifying cavity 101 and supplement water in time as needed, thereby reducing the interruption of humidification caused by lack of water.

[0060] It should be noted that the position element 60 in the present embodiment can be selected from existing light-shielding sheets or light-reflecting sheets, and the position sensor can be selected from existing photoelectric sensors to realize position detection through cooperation of infrared light and the light-shielding sheets or light-reflecting sheets. Of course, the position element 60 can also be selected from permanent magnet structures, and the position detector 61 can be selected from existing Hall sensors to realize position detection through cooperation of magnetic fields. How the position detector 61 realizes detection of the position of the position element 60 and sends the position signal are all existing technologies and do not belong to the protection scope of the present application, and thus will not be described here.

[0061] Further, the machine body 10 comprises a casing 12 and a water tank 13, the humidifying cavity 101 is arranged in the water tank 13, and the casing 12 is detachably capped on the top end of the water tank 13, and the flow guide cavity 102 and the flow guide assembly 40 are arranged on the top of the casing 12.

[0062] On the basis of the above structure, the machine body 10 in the embodiment is assembled by the casing 12 and the water tank 13. During installation, the casing 12 can be detachably capped on the top end of the water tank 13. For example, a buckle structure is arranged on the end of the casing 12 close to the water tank 13, a buckle matching structure, such as a buckle slot or a buckle hole structure, is arranged on the top end of the water tank 13, the buckle is buckled into the buckle slot or the buckle hole, so that the casing 12 and the water tank 13 are connected in a clamping manner, and the detachable connection is realized. When the user replenishes water, the user only needs to detach the casing 12 and directly add water to the humidifying cavity 101 in the water tank 13. At the same time, when it is necessary to replace or clean the components inside the humidifying cavity 101, the user only needs to detach the casing 12, and the operation is simple.

[0063] Of course, the casing 12 and the water tank 13 can also be detachably connected in a manner of a latch, magnetic attraction, etc.

[0064] In addition, the flow guide cavity 102 and the flow guide assembly 40 are arranged on the top of the casing 12, and the water tank 13 bears the functions of water storage and humidification, so that the flow guide assembly 40 and the humidifying member 20 are respectively arranged in an independent modular manner. When it is necessary to clean the humidifying member 20 or clean the water tank 13, the casing 12 only needs to be detached from the top end of the water tank 13, so that the humidifying member 20, the water suction section 221 and other components in the water tank 13 can be directly contacted without touching the flow guide assembly 40 on the top of the casing 12, so as to reduce damage and interference to the internal structure of the casing 12. Similarly, if the flow guide assembly 40 needs to be replaced and maintained, the casing 12 only needs to be taken down for maintenance without carrying the heavy water tank 13, and the operation is more convenient.

[0065] As a preferred, on the basis that the machine body 10 is assembled by the casing 12 and the water tank 13, the air inlet 103 in the embodiment can be arranged on the casing 12 and spacedly distributed along the circumference of the casing 12. At the same time, the filter member 50 is attached to the inside of the casing 12 and detachably connected with the internal structure of the casing 12, so as to be capped at the air inlet 103.

[0066] Further, the air guide assembly 40 comprises an air outlet main structure 42 and a fan structure 41, the air outlet main structure 42 is installed at the top end of the cabinet 12, the top end of the cabinet 12 is provided with a plurality of air outlets 104, the plurality of air outlets 104 are arranged around the circumferential side of the air outlet main structure 42; the end of the air outlet main structure 42 is provided with a water inlet part 421, the water inlet part 421 is communicated with a water guide part 411, the water guide part 411 is communicated to the water tank 13; the water guide part 411 and the air outlet 104 are arranged in a circumferential staggered manner on the air outlet main structure 42; the fan structure 41 is arranged in the inner cavity of the air outlet main structure 42, and the air outlet main structure 42 and the fan structure 41 have an air outlet air duct 43, the top end of the air outlet air duct 43 is communicated with the air outlet 104, and the bottom end of the air outlet air duct 43 is communicated with the humidifying space 201.

[0067] Specifically, by arranging the air outlet main structure 42 at the top end of the cabinet 12 as the installation basis of the fan structure, the fan structure 41 can be arranged in the air outlet main structure 42 during installation, and the air outlet main structure 42 provides stable support for the fan structure 41, so that the fan structure 41 is more stable during operation.

[0068] In addition, the water inlet part 421 is arranged at the top end of the air outlet main structure 42, the plurality of air outlets 104 are arranged around the circumferential side of the water inlet part 421, and the water guide part 411 and the air outlet 104 are completely staggered in the circumferential direction, so that the user can directly operate the water inlet part 421 in the central region when adding water, avoiding the circumferential air outlet 104, and thus the water can be added without stopping the machine, which is convenient to operate and does not affect the continuous operation of the humidifying function. At the same time, since the water inlet part 421 is arranged in the central region surrounded by the plurality of air outlets 104, the central region has weak wind power and is easy to form a low pressure area due to the air diffusion characteristics, so arranging the water inlet part 421 in the central region can maximize the use of the top space compared to arranging the water inlet part 421 and the plurality of air outlets 104 side by side, while avoiding the water inlet structure from blocking the air outlet 104, so as to reduce the influence of the water inlet part 421 on the air outlet 104.

[0069] It should be noted that the water inlet part 421 can be a groove structure or a pipeline structure at the top end of the air outlet main structure 42, and the water guide part 411 can be formed by a pipe or a shell with a hollow structure inside. During installation, the water guide part 411 is arranged along the inner side of the air outlet air duct 43 and is sealed and communicated with the water inlet part 421. When adding water, the water flow is directly guided into the humidifying cavity 101 through the water inlet part 421 and the water guide part 411, without passing through the fan structure 41 or interfering with the airflow of the air outlet air duct 43, so that the fan structure 41 does not need to be stopped during water adding operation, which is convenient for the user to operate.

[0070] In addition, the shape, size and number of the water guide part 411 can be controlled to reduce the influence of the water guide part 411 on the air outlet, which can be set according to actual installation requirements.

[0071] More specifically, the air outlet main structure 42 has an air outlet air duct 43 with the fan structure 41, so that when purifying and humidifying air, the fan structure 41 is started, so that a negative pressure can be formed in the flow guide cavity 102 to guide external airflow to enter the casing 12 through the air inlet 103. After the airflow enters, under the guidance of the fan structure 41, the airflow is guided to the flow guide cavity 102 in turn through the air inlet interval 105, the humidifying piece 20, and the humidifying space 201, and then flows to the air outlet air duct 43, and then the airflow is guided to flow to the multiple air outlets 104 on the side of the air outlet main structure 42 to be guided out, and the airflow flows along the predetermined path.

[0072] As a preferred, referring to Figure 5 、 Figure 6 In the embodiment, the end of the air outlet main structure 42 is provided with a water inlet groove 4211, which is formed into a water inlet part 421.

The drain pipe passes through the air duct and penetrates to the outside of the air outlet main structure 42. The drain pipe forms a water guide part 411.

[0073] Specifically, during assembly, the water inlet groove 4211 is arranged at the end of the air outlet main structure 42 to form the water inlet part 421 on the air outlet main structure. When the end of the air outlet main structure 42 is arranged upward or laterally, the user can directly add water to the water inlet groove 4211 from the end of the air outlet main structure 42.

[0074] At the same time, the groove wall of the water inlet groove 4211 is provided with a water guide outlet 4212. The water inlet groove 4211 is connected with a drain pipe through the water guide outlet 4212. The drain pipe passes through the air outlet air duct 43 and penetrates to the outside of the air outlet main structure 42. The drain pipe forms a water guide part 411.

[0075] When the end of the air outlet main structure 42 is arranged upward, the top of the water inlet groove 4211 has an opening for adding water. The water guide outlet 4212 is arranged on the side wall or the bottom wall of the water inlet groove 4211. In order to avoid affecting the arrangement of the fan structure 41 by the water guide outlet 4212, the water guide outlet 4212 is arranged on the side wall of the water inlet groove 4211.
