Description

Technical Field

[0001] This utility model relates to the field of air purification and humidification technology, and in particular to a purification and humidification device. Background Technology

[0002] Currently, most mainstream humidifiers on the market use the evaporative humidification principle. This involves a built-in fan driving airflow through a pre-wetted filter. The contact between the airflow and the wet filter causes the moisture on the filter to evaporate naturally and be absorbed into the airflow, ultimately achieving air humidification. To maintain the filter's continuous moisture, some products use the filter's own water absorption properties for siphon water supply. This involves using the capillary action of the filter material to draw water from the water tank to the entire filter, thus automatically wetting the filter.

[0003] However, when this siphon water supply structure is in use, the water level in the tank will gradually decrease as the humidification process continues to consume water, causing the contact depth between the filter and the water surface to change continuously. This results in uneven water absorption in different areas of the filter, with some areas being too wet and others being too dry. Consequently, when the airflow passes through the filter, it does not make sufficient contact with the effective humidification area, and the contact area is unstable. Ultimately, this leads to unstable humidification output of the humidifier and affects the humidification efficiency of the equipment. Utility Model Content In order to overcome at least one of the defects of the prior art, the present invention provides a humidifier that improves humidification efficiency by setting an isolation cover above the humidifying element and guiding the airflow through the humidified area of ​​the humidifying element, thereby increasing the effective contact area between the airflow and the moisture.

[0004] The technical solution adopted by this utility model to solve its problem is: A purifying humidifier, comprising: The machine body includes a humidification chamber, a guide chamber, an air inlet, an air outlet, and an isolation cover. The isolation cover is connected to the lower part of the guide chamber and located above the humidification chamber. The guide chamber is in communication with the humidification chamber. The air outlet is in communication with the guide chamber. A humidifier is installed in the humidification chamber and has a humidification space inside. The humidifier includes a water absorption section and a humidification section, which are distributed vertically along the axial direction of the humidifier. The water absorption section is used to guide water flow to the humidification section. The isolation cover is enclosed in the humidification section and forms an air inlet gap with the water absorption section. The air inlet gap is connected to the air inlet and the humidification space. A flow guiding component is disposed in the flow guiding cavity and is used to guide the flow of air.

[0005] Furthermore, the purifying humidifier includes a filter element, which is detachably installed inside the body; the filter element is located inside the air inlet and spaced apart from the outer side of the humidifying element.

[0006] Furthermore, the humidifying component includes a filter frame and a humidifying filter; the humidifying filter is disposed on the filter frame; the inner side of the filter frame forms the humidifying space; the humidifying filter has a water absorption section and a humidifying section, the water absorption section being connected to the bottom end of the humidifying section; The humidification chamber is equipped with a buoyancy component, which surrounds the water absorption section and is used to drive the humidification component to move along its own axis when floating.

[0007] Furthermore, the filter screen frame is provided with a first positioning frame and a second positioning frame. The first positioning frame is detachably connected to the top of the humidifying filter screen. The second positioning frame is provided at the bottom of the filter screen frame and is provided with a positioning groove. The positioning groove extends along the circumference of the filter screen frame, and the water absorption section is installed in the positioning groove. The buoyancy member surrounds the top of the positioning groove.

[0008] Furthermore, the edge of the first positioning frame is provided with a connecting edge, one end of which is connected to the top of the first positioning frame, and the other end of which is spaced apart from the outer peripheral wall of the first positioning frame; the connecting edge abuts against the inner wall of the isolation cover and is used to guide the humidifying component to slide and cooperate with the isolation cover when the buoyancy component floats.

[0009] Furthermore, a guide surface is provided on the connecting edge, which is used to guide the connecting edge to slide and engage with the inner wall of the isolation cover when the connecting edge is subjected to force.

[0010] Furthermore, the humidifying element is provided with a position element, and the body is provided with a position detector, which is used to detect the position of the position element.

[0011] Furthermore, the machine body includes a casing and a water tank, with the humidification chamber located in the water tank; the casing is detachably covered at the top of the water tank; and the flow guiding chamber and the flow guiding assembly are located at the top of the casing.

[0012] Furthermore, the airflow guiding component includes an air outlet main structure and a fan structure. The air outlet main structure is installed on the top of the housing, and the top of the housing is provided with multiple air outlets, which surround the periphery of the air outlet main structure. A water inlet is provided at the end of the air outlet main structure, and the water inlet is connected to a water guiding part, which is connected to the water tank. The water guiding part and the air outlets are staggered in the circumferential direction of the air outlet main structure. The fan structure is installed inside the air outlet main structure. There is an air outlet duct between the air outlet main structure and the fan structure. The top end of the air outlet duct is connected to the air outlet, and the bottom end of the air outlet duct is connected to the humidification space.

[0013] Furthermore, the end of the air outlet main structure is provided with a water inlet groove; the water inlet groove is formed as the water inlet section; The wall of the water inlet groove is provided with a water outlet, and the water inlet groove is connected to a drain pipe through the water outlet. The drain pipe passes through the air duct and extends to the outside of the air outlet main structure, and the drain pipe forms the water guide section.

[0014] In summary, the purifying humidifier provided by this utility model has the following technical effects: In use, the isolation cover is placed outside the humidification section, forming an air inlet gap between it and the water absorption section. When airflow is guided into the air inlet by the air guide components, it is blocked by the isolation cover and can only enter the humidification space through this air inlet gap. Since the air inlet gap is adjacent to the water absorption section, which has the largest effective wetting area in the humidification component, the airflow can fully contact the moisture as it flows through this area, thereby increasing the effective contact area between the airflow and moisture and improving humidification efficiency.

[0023] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0024] See Figures 1 to 9 This utility model discloses a purifying humidifier, including a body 10, a humidifying component 20, and a flow guiding assembly 40. The body 10 is provided with a humidifying chamber 101, a flow guiding chamber 102, an air inlet 103, an air outlet 104, and an isolation cover 11. The isolation cover 11 is connected to the lower part of the flow guiding chamber 102 and located above the humidifying chamber 101. The flow guiding chamber 102 can communicate with the humidifying chamber 101, and the air outlet 104 is communicated with the other end of the flow guiding chamber 102 away from the humidifying chamber 101.

[0025] Additionally, a humidifier 20 is installed in the humidification chamber 101, and a humidification space 201 is provided inside the humidifier 20. The humidifier 20 includes a water absorption section 221 and a humidification section 222, which are distributed vertically along the axial direction of the humidifier 20. The water absorption section 221 is used to guide water flow to the humidification section 222. An isolation cover 11 is placed around the humidification section 222 and forms an air inlet gap 105 with the water absorption section 221. The air inlet gap 105 is connected to the air inlet 103 and the humidification space 201. The aforementioned airflow guiding component 40 is located in the airflow guiding cavity 102. When the airflow guiding component 40 is activated, it can guide the airflow to the air inlet 103. After being introduced through the air inlet 103, the airflow flows sequentially through the air inlet interval 105, the humidifier 20, the humidification space 201, and the airflow guiding cavity 102, and is finally discharged to the external environment through the air outlet 104.

[0026] Based on the above structure, taking the water-absorbing section 221 of the humidifier 20 as the section immersed in the water in the humidification chamber 101 and the humidification section 222 as the section exposed above the water surface as an example: when the humidifier 20 is assembled into the humidification chamber 101, the water-absorbing section 221 continuously absorbs water from the humidification chamber 101 by means of the capillary action and adsorption properties of its own material, and through the water conduction effect inside the material, the absorbed water is stably transported to the humidification section 222 exposed above the water surface, so that the humidification section 222 maintains a continuously moist state.

[0027] Subsequently, the isolation cover 11 is installed on the outer periphery of the humidification section 222, with a gap reserved between the bottom of the isolation cover 11 and the upper part of the water absorption section 221, forming an air inlet gap 105. Since the air inlet gap 105 is adjacent to the water absorption section 221, and the water absorption section 221 is the water source for the humidification section 222, the moisture transferred to the corresponding area of ​​the air inlet gap 105 in the humidification section 222 is the most abundant. The area corresponding to the air inlet gap 105 is the area with the largest effective humidification area and the most uniform humidity in the humidification section 222.

[0028] Meanwhile, the size of the air inlet interval 105 can be reasonably designed in combination with the moisture conduction range of the humidifier 20 and the minimum water level threshold of the humidifier cavity 101, so that even if the water level of the humidifier cavity 101 continues to decrease to the minimum water level during the humidification process, the area of ​​the humidifier 20 corresponding to the air inlet interval 105 can still maintain the maximum effective humidification area stably, reducing the problem of shrinkage of the humidification area and sudden drop in humidification volume due to water level fluctuations.

[0029] When the equipment is running, the airflow is guided by the air guide assembly 40 and introduced from the air inlet 103. At this time, because the isolation cover 11 surrounds the humidification section 222, it effectively blocks the airflow above the humidification component 20, forcing the airflow to flow only along the air inlet gap 105 between the bottom of the isolation cover 11 and the water absorption section 221 into the humidification space 201 inside the humidification component 20. In this way, the airflow must pass through the area with the largest effective humidification area above the water absorption section 221 before entering the humidification space 201. During this process, the airflow comes into full contact with the moisture in the area with the largest humidification area of ​​the humidification component 20, allowing the airflow to fully absorb moisture, thereby achieving effective humidification of the airflow. This increases the humidity of the airflow finally discharged through the air outlet 104, thereby reducing the problem of unstable humidification and improving the overall humidification efficiency of the equipment.

[0030] Furthermore, in this embodiment, the humidification chamber 101 can be formed by assembling an independent shell or box with a hollow internal structure at the bottom of the body 10; alternatively, it can be formed by directly molding a hollow cavity inside the body 10, so that the body 10 itself has a built-in humidification chamber 101. The flow guiding cavity 102 is correspondingly disposed above the body 10, also adopting a hollow structure design, so that a flow guiding channel is formed above the body 10. After the body 10 is assembled, the humidification chamber 101, the humidification space 201 (inside the humidification component 20), and the flow guiding cavity 102 can be distributed from bottom to top inside the body 10.

[0031] When the device is running, the airflow is guided by the air guide component 40 through the air inlet 103, and after entering the body 10, it enters the humidification space 201 through the air inlet gap 105 at the bottom of the isolation cover 11. After fully contacting the humidified area of ​​the humidifying element 20 to complete humidification, it continues to flow from bottom to top to the upper guide cavity 102, and finally exits through the air outlet 104. During this process, since the airflow flows from bottom to top, the tiny particles (such as dust, impurities, etc.) carried in the airflow will naturally settle under their own gravity. The settled particles can be adsorbed by the water at the bottom of the humidification cavity 101 or retained inside the cavity, so that the exited airflow achieves downward purification while completing humidification, thereby improving indoor air quality.

[0032] It should be noted that the humidifier 20 in this embodiment can directly adopt existing air humidification structures, such as porous honeycomb humidification nets. These humidification nets, through a special porous honeycomb structure design, can effectively increase the contact area between water and air, and achieve air humidity improvement by means of the uniform distribution and rapid evaporation of water on the porous structure surface.

[0033] Of course, the humidifier can also be an existing sponge-type porous humidifier 20, for example: using a highly elastic, highly absorbent sponge (such as polyurethane sponge), the rich interconnected pores inside can store a large amount of water, and can be quickly soaked when in contact with water flow, adapting to the humidification needs under different water levels, and can also achieve the humidification of air humidity.

[0034] More specifically, the isolation cover 11 in this embodiment can adopt a hollow cover or shell structure. During assembly, it can be integrally formed with the body 10, or it can be separately processed by mechanical cutting, injection molding and other processes, and then assembled into the body 10 by means of buckles, bolts and other detachable methods. The specific configuration can be set according to actual needs.

[0035] In addition, the flow guiding component 40 can be selected from existing small axial flow fans, centrifugal fans or cross flow fans, etc. During assembly, the flow guiding component 40 can be installed on the upper part of the flow guiding cavity 102 (near the inside of the air outlet 104) by means of snap-fit ​​or bolts, and the air outlet 104 is aligned with the inlet of the flow guiding cavity 102 to guide the airflow.

[0036] Furthermore, the purifying humidifier includes a filter element 50, which is detachably installed inside the body 10. The filter element 50 is located inside the air inlet 103 and is spaced apart from the outer side of the humidifying element 20.

[0037] Based on this structure, by placing the filter element 50 inside the air inlet 103, the airflow will first flow through the filter element 50 when it is introduced through the air inlet 103. The filter element 50 filters out the tiny particles in the airflow. After the airflow is initially filtered, it flows to the air inlet interval 105 and is introduced into the humidification space 201. Then it continues to flow from bottom to top to the guide cavity 102 and the air outlet 104. During the process of flowing from bottom to top, it sinks down again for purification, so that the finally discharged airflow undergoes double filtration and the purification effect is better.

[0038] In addition, the filter element 50 and the humidifier 20 are spaced apart on the outside, and an independent airflow channel is formed by reserving a reasonable gap. This reduces the possibility of the humidifier 20 sticking to the surface of the filter element 50 due to continuous moisture, or the filter element 50 absorbing moisture and clogging the pores. This reduces the obstruction of airflow, allowing the filtered airflow to flow smoothly along the spaced channel to the air inlet gap 105.

[0039] It should be noted that the filter element 50 mentioned above can directly adopt the air filtration structure in related technologies, such as: pre-filter (such as nylon mesh), HEPA filter and activated carbon substrate filter. The pre-filter, HEPA filter and activated carbon substrate filter are all porous honeycomb structures, so that air can be purified by passing through the filter element 50.

[0040] During installation, the filter element can be connected to the body 10 in a detachable manner, such as by snap-fit ​​or by screws, bolts or other threaded connections, and is covered inside the air inlet 103, making the filter element 50 detachable. In this way, the user can periodically remove the filter element 50 for cleaning and replacement without disassembling the entire body 10, making the operation simple.

[0041] Furthermore, the humidifying component 20 includes a filter frame 21 and a humidifying filter 22, with the humidifying filter 22 surrounding the filter frame 21. A humidifying space 201 is formed inside the filter frame 21, and the aforementioned water absorption section 221 and humidifying section 222 are formed on the humidifying filter 22. The water absorption section 221 is connected to the bottom end of the humidifying section 222 and is used to guide water flow to the humidifying section 222. At the same time, a buoyancy member 30 is provided in the humidifying chamber 101, surrounding the water absorption section 221 and used to drive the humidifying component 20 to move along its own axis when floating.

[0042] Specifically, during assembly, the filter frame 21 serves as the installation base, with the humidifying filter 22 enclosed around its outer perimeter. The filter frame 21 provides stable support for the humidifying filter 22. Subsequently, the buoyancy component 30 (such as existing foamed plastic, hollow floats, etc.) is connected to the humidifying filter 22 or the filter frame 21 in a detachable (such as snap-fit ​​or threaded connection) or fixed manner, so that the buoyancy component 30 surrounds the water absorption section 221. Through reasonable design, it neither obstructs the contact area between the water absorption section 221 and the water body, nor hinders the upward conduction of water through the water absorption section 221, thus not affecting the water absorption effect of the humidifying filter 22.

[0043] After assembly, the buoyancy of the buoyancy component 30 allows the entire humidifier 20 to float on the water surface of the humidification chamber 101. When the water level inside the humidification chamber 101 decreases as the humidification process is consumed, the buoyancy component 30 will float downwards synchronously along the axial direction of the humidifier 20 (i.e., the vertical direction of the body 10) with the water level, and drive the entire humidifier 20 to move downwards synchronously through linkage. Conversely, if the water level rises, the buoyancy component 30 will drive the humidifier 20 to move upwards, so that the water absorption section 221 always maintains a stable effective contact depth with the water body, reducing insufficient water absorption due to water level fluctuations. At the same time, the humidification section 222 will also adjust its position along with the humidifier 20, so that it can always be aligned with the air inlet interval 105, so that the humidification area corresponding to the air inlet interval 105 can continuously maintain the maximum effective humidification area, reducing the phenomenon of unstable humidification volume of the humidifier 20 due to water level drop.

[0044] It should be noted that the air inlet gap 105 between the bottom of the isolation cover 11 and the water absorption section 221 can initially be combined with the water conduction range of the humidifier 20 and the floating stroke of the buoyancy component 30 to drive the humidifier 20, so that the buoyancy component 30 drives the humidifier 20 to descend to the lowest water level of the humidification chamber 101. The area of ​​the humidification filter 22 corresponding to the air inlet gap 105 can still maintain the maximum effective humidification area. In this way, no matter whether the water level of the humidification chamber 101 is at a high level or a low level, when the airflow flows through the air inlet gap 105 and passes through the humidification filter 22, it can fully contact the maximum effective humidification area of ​​the humidification filter 22, improve the contact efficiency between the airflow and the water, and thus continuously improve the humidification efficiency of the equipment.

[0045] More specifically, the filter frame 21 in this embodiment adopts a mesh frame structure, see reference. Figure 7 The multiple mesh openings around the filter screen frame 21 allow water to flow evenly to the humidifying filter screen 22, ensuring that the humidifying filter screen 22 can fully contact the water after installation and achieve a uniform humidification effect.

[0046] Furthermore, after the humidifying filter 22 and the filter frame 21 are assembled, the outer peripheral wall of the humidifying filter 22 can be fitted with the inner wall of the isolation cover 11 with a clearance fit to form a sliding fit. When the isolation cover 11 is placed over the humidifying filter 22, the humidifying component 20 can slide smoothly along the axial direction of the isolation cover 11 (i.e., the vertical direction of the body 10) under the drive of the buoyancy component 30, so as to guide the up and down floating of the humidifying component 20 along the axial direction of the isolation cover 11, and the stroke is controllable.

[0047] Meanwhile, the close fit between the inner wall of the isolation cover 11 and the outer peripheral wall of the humidifying filter 22 restricts the horizontal displacement of the humidifying element 20, effectively reducing the left and right offset and shaking of the entire humidifying element 20 caused by water level changes, airflow impact, or slight shaking of the equipment. This reduces the fluctuation in the size of the air inlet interval 105 caused by the shaking of the humidifying element 20, thereby reducing the probability of insufficient contact between the airflow and the humidifying filter 22 at the air inlet interval 105 and unstable contact area. This allows the airflow to stably contact the maximum effective humidification area of ​​the humidifying filter 22, further improving the humidification efficiency.

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

[0049] Furthermore, the filter 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 of the humidifying filter 22, and the second positioning frame 24 is provided at the bottom of the filter frame 21. The second positioning frame 24 is provided with a positioning groove 241, which extends circumferentially along the filter frame 21. The water absorption section 221 is installed in the positioning groove 241, and the buoyancy member 30 is arranged above the positioning groove 241.

[0050] Based on this structure, see Figures 7 to 9 The water absorption section 221 is installed by setting a positioning groove 241 at the bottom of the filter frame 21. The positioning groove 241 has multiple mesh holes in its circumferential direction. When the water absorption section 221 is embedded in the positioning groove 241, the water in the humidification chamber 101 can smoothly enter the interior of the positioning groove 241 through these mesh holes and fully contact the water absorption section 221, ensuring that the water absorption function of the water absorption section 221 is not affected by the installation structure, and the water can be continuously and stably conducted to the humidification section 222.

[0051] Meanwhile, after the water absorption section 221 is installed, the groove wall of the positioning groove 241 can radially limit the water absorption section 221, thereby restricting the horizontal displacement of the entire humidifying filter 22, effectively reducing the shaking of the humidifying component 20 caused by airflow impact and water level fluctuation during use, so that the position of the humidifying filter 22 and the air inlet interval 105 is relatively stable.

[0052] After the water absorption section 221 is installed, the humidification section 222 above it surrounds the outer periphery of the filter screen frame 21. At this time, the buoyancy component 30 can be fixed to the upper end face of the positioning groove 241 by means of connectors (such as clips, bolts) or adhesive, so that it surrounds the outside of the water absorption section 221 in a ring shape, so that the buoyancy component 30 can drive the entire humidification component 20 to float up and down synchronously. Furthermore, since the buoyancy component 30 avoids the mesh area of ​​the positioning groove 241, it will not block the water flow channel, and therefore the buoyancy component 30 will not interfere with the water absorption function of the water absorption section 221 after installation.

[0053] More specifically, after the humidifying filter 22, the buoyancy component 30 and the second positioning frame 24 are assembled, the first positioning frame 23 can be connected to the top of the humidifying filter 22 by means of detachable methods such as snap-fit ​​or screw thread connection, to limit the top of the humidifying filter 22. Combined with the limiting function of the second positioning frame 24 at the bottom of the humidifying filter 22, the humidifying filter 22 is fixed in the vertical direction, reducing the probability of the humidifying filter 22 moving up and down, making the overall installation of the humidifying filter 22 more stable, and improving the stability of the humidification effect.

[0054] Furthermore, in this embodiment, a connecting edge 231 is provided on the edge of the first positioning frame 23. One end of the connecting edge 231 is connected to the top of the first positioning frame 23, and the other end of the connecting edge 231 is spaced apart from the outer peripheral wall of the first positioning frame 23. The connecting edge 231 abuts against the inner wall of the isolation cover 11 and guides the humidifying component 20 to slide and cooperate with the isolation cover 11 when the buoyancy component 30 floats.

[0055] Based on this structure, refer to the following during assembly: Figure 7 The connecting edge 231 is extended along the circumference of the first positioning frame 23. The connecting edge 231 increases the contact guide area between the humidifying component 20 and the isolation cover 11. Compared with the method of relying solely on the humidifying filter 22 and the isolation cover 11, it can more accurately guide the humidifying component 20 to move along the axial (vertical) direction of the isolation cover 11, reducing the phenomenon of jamming and deviation during its floating process.

[0056] Furthermore, since the other end of the connecting edge 231 is spaced apart from the outer peripheral wall of the first positioning frame 23, this gap forms an elastic deformation space. When the connecting edge 231 contacts the inner wall of the isolation cover 11 and is subjected to radial pressure, this gap can accommodate the slight elastic deformation of the connecting edge 231. This reduces the sliding jamming of the humidifying component 20 due to excessive tightness, and also compensates for minor errors in the fitting gap through deformation, so that the connecting edge 231 and the inner wall of the isolation cover 11 can effectively fit together. At the same time, it reduces the frictional wear between the connecting edge 231 and the isolation cover 11, indirectly extending the service life of both.

[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 under force, the guide surface 232 can guide the connecting edge 231 to slide against the inner wall of the isolation cover 11. When the humidifying component 20 floats up and down with the buoyancy component 30, and the connecting edge 231 slides relative to the inner wall of the isolation cover 11, if the guide surface 232 is an inclined surface, during sliding, the inclined surface of the guide surface 232 will transform the surface contact into a line contact through its own inclined design, reducing the friction area and dispersing the radial pressure, thereby reducing the risk of jamming. If the guide surface 232 is an arc surface, during sliding, the arc surface will smoothly transition between the connecting edge 231 and the isolation cover 11 with a smooth arc transition, reducing the risk of jamming during the sliding cooperation process.

[0058] Furthermore, the humidifier 20 is provided with a position element 60, and the body 10 is provided with a position detector 61, which is used to detect the position of the position element 60.

[0059] Based on this structure, by setting a position element 60 on the humidifier 20, when the water level in the humidifier chamber 101 changes, the buoyancy element 30 drives the humidifier 20 to float up and down, and the position element 60 moves axially synchronously with the humidifier 20. Since a position detector 61 is installed at the corresponding position on the body 10, the position detector 61 can capture the displacement signal of the position element 60 in real time and transmit the position signal to the back-end control panel to provide feedback to the user, so that the user can grasp the water level status in the humidifier chamber 101 and replenish water as needed in a timely manner, reducing humidification interruption due to water shortage.

[0060] It should be noted that in this embodiment, the position element 60 can be an existing light-shielding sheet or reflector, and the position sensor can be an existing photoelectric sensor, achieving position detection through the cooperation of infrared light with the light-shielding sheet or reflector. Alternatively, the position element 60 can be a permanent magnet structure, and the position detector 61 can be an existing Hall sensor, achieving position detection through the cooperation of a magnetic field. How the position detector 61 detects the position of the position element 60 and sends a position signal is specific to existing technology and is not within the scope of this application; therefore, it will not be elaborated upon here.

[0061] Furthermore, the body 10 includes a housing 12 and a water tank 13. The humidification chamber 101 is located in the water tank 13. The housing 12 is detachably sealed to the top of the water tank 13. The flow guiding chamber 102 and the flow guiding assembly 40 are located on the top of the housing 12.

[0062] Based on the above structure, the body 10 in this embodiment is assembled from a housing 12 and a water tank 13. During installation, the housing 12 can be detachably sealed to the top of the water tank 13. For example, a buckle structure is provided at one end of the housing 12 near the water tank 13, and a slot or groove structure matching the buckle is provided at the top of the water tank 13. The buckle is snapped into the slot or groove so that the housing 12 and the water tank 13 are engaged and connected, making it detachable. When the user adds water, only the housing 12 needs to be removed, and water can be added directly to the humidification chamber 101 in the water tank 13. At the same time, when it is necessary to replace or clean the components inside the humidification chamber 101, only the housing 12 needs to be removed, making the operation simple.

[0063] Of course, the housing 12 and the water tank 13 can also be detachably connected by means of pins, magnets, etc.

[0064] Furthermore, the flow guide cavity 102 and the flow guide assembly 40 are located on the top of the casing 12, while the water tank 13 serves as both a water storage and humidification unit. This allows the flow guide assembly 40 and the humidification component 20 to be independently modularized. When cleaning the humidification component 20 or removing scale from the water tank 13, the casing 12 can be easily detached from the top of the water tank 13 to directly access the humidification component 20, water intake section 221, and other components inside the water tank 13, without needing to touch the flow guide assembly 40 on the top of the casing 12, thus reducing the risk of damage or interference to the internal structure of the casing 12. Similarly, if the flow guide assembly 40 needs to be replaced or maintained, only the casing 12 needs to be removed for maintenance, eliminating the need to carry the heavy water tank 13, making the operation more convenient.

[0065] Preferably, based on the assembly of the housing 12 and water tank 13 on the main body 10, the air inlet 103 in this embodiment can be set on the housing 12 and distributed circumferentially along the housing 12. At the same time, the filter element 50 is attached to the inside of the housing 12 and is detachably connected to the internal structure of the housing 12, so that it covers the air inlet 103.

[0066] Furthermore, the airflow guiding component 40 includes an air outlet main structure 42 and a fan structure 41. The air outlet main structure 42 is installed on the top of the housing 12. The top of the housing 12 is provided with multiple air outlets 104, which surround the periphery of the air outlet main structure 42. The end of the air outlet main structure 42 is provided with a water inlet 421, which is connected to a water guide 411, which is connected to a water tank 13. The water guide 411 and the air outlets 104 are staggered in the circumferential direction of the air outlet main structure 42. The fan structure 41 passes through the inner cavity of the air outlet main structure 42. There is an air outlet duct 43 between the air outlet main structure 42 and the fan structure 41. The top of the air outlet duct 43 is connected to the air outlets 104, and the bottom of the air outlet duct 43 is connected to the humidification space 201.

[0067] Specifically, by setting the air outlet main structure 42 at the top of the casing 12 as the installation base of the fan structure, the fan structure 41 can be inserted into the air outlet main structure 42 during installation, so that the air outlet main structure 42 provides stable support for the fan structure 41, making it more stable during operation.

[0068] Furthermore, the water inlet 421 is located at the top of the main air outlet structure 42, with multiple air outlets 104 distributed around it. The water guide 411 and the air outlets 104 are completely offset circumferentially. This allows users to directly operate the water inlet 421 in the central area when adding water, avoiding the surrounding air outlets 104, thus completing water replenishment without stopping the machine. This is convenient and does not affect the continuous operation of the humidification function. Simultaneously, since the water inlet 421 is located in the central area formed by the multiple air outlets 104, this central area has weaker airflow and is prone to forming a low-pressure zone. Therefore, placing the water inlet 421 in this central area maximizes the use of top space compared to placing the water inlet 421 alongside the multiple air outlets 104, while also preventing the water inlet structure from obstructing the air outlets 104, thus reducing the impact of the water inlet 421 on the airflow from the air outlets 104.

[0069] It should be noted that the water inlet 421 can be a groove structure or a pipe structure at the top of the air outlet main structure 42, while the water guide 411 can be formed by a pipe or shell with a hollow internal structure. During installation, the water guide 411 is arranged along the inner side of the air outlet duct 43 and is sealed and connected to the water inlet 421. When adding water, the water flows directly into the humidification chamber 101 through the water inlet 421 and the water guide 411, without passing through the fan structure 41 or interfering with the airflow of the air outlet duct 43. Therefore, the fan structure 41 does not need to be stopped during the water adding operation, which is convenient for the user.

[0070] In addition, the influence of the water guide 411 on the air outlet can be reduced by controlling the shape, size and number of the water guide 411. The specific settings can be made according to the actual installation requirements.

[0071] More specifically, there is an air outlet duct 43 between the main air outlet structure 42 and the fan structure 41. When purifying and humidifying the air, the fan structure 41 is activated, which can create negative pressure in the guide cavity 102, guiding the external airflow into the casing 12 through the air inlet 103. After the airflow enters, under the guidance of the fan structure 41, the airflow passes through the air inlet interval 105, the humidifier 20 and the humidification space 201 in sequence before being introduced into the guide cavity 102. The airflow then flows through the guide cavity 102 to the air outlet duct 43, and is then guided by the air outlet duct 43 to multiple air outlets 104 around the main air outlet structure 42 for discharge, guiding the airflow to flow along a predetermined path.

[0072] As a preferred option, see [reference] Figure 5 , Figure 6 In this embodiment, the end of the air outlet main structure 42 is provided with a water inlet groove 4211, which is formed as a water inlet part 421. The groove wall of the water inlet groove 4211 is provided with a water guide outlet 4212. The water inlet groove 4211 is connected to a drain pipe through the water guide outlet 4212. The drain pipe passes through the air duct and extends to the outside of the air outlet main structure 42, forming a water guide part 411.

[0073] Specifically, during assembly, a water inlet groove 4211 is provided at the end of the air outlet main body structure 42, so that a water inlet part 421 is formed on the air outlet main body. When the end of the air outlet main body structure 42 is set upward or sideways, the user can directly add water to the water inlet groove 4211 from the end of the air outlet main body structure 42.

[0074] Meanwhile, the wall of the water inlet groove 4211 is provided with a water outlet 4212. The water inlet groove 4211 is connected to a drain pipe through the water outlet 4212. The drain pipe passes through the air outlet duct 43 and extends to the outside of the air outlet main structure 42, forming a water guide section 411.

[0075] When the end of the main air outlet structure 42 is set upward, the top of the water inlet groove 4211 has an opening for adding water, and the water outlet 4212 is set on the side wall or bottom wall of the water inlet groove 4211. In order to avoid the water outlet 4212 affecting the setting of the fan structure 41, the water outlet 4212 is set on the side wall of the water inlet groove 4211. When the water outlet 4212 is set on the side wall of the water inlet groove 4211, in order to facilitate drainage and avoid water accumulation in the water inlet groove 4211, the water outlet 4212 is set close to the bottom wall of the water inlet groove 4211.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
