Description

Technical Field

[0001] The present invention relates to the technical field of electrical appliances, and particularly to an air purification and humidification device. Background Art

[0002] An air purification and humidification device is a commonly used electrical appliance for removing foreign matters such as lint and dust in the air, and can also be used to increase the air humidity.

[0003] In related technologies, a humidifying wheel is usually arranged at the air inlet of a purification device in an air purification and humidification device. After air enters the purification device, it first flows through a filter element for filtering and removing foreign matters in the air, and then the filtered clean air flows through the humidifying wheel. The water on the humidifying wheel will flow out of the purification device along with the air to achieve the purpose of increasing the air humidity.

[0004] However, the moisture in the humidifying wheel will increase the humidity of the filter element at the same time, which easily causes bacteria to breed on the filter element and results in secondary air pollution. Summary of the Invention

[0005] In view of the above problems, an embodiment of the present invention provides an air purification and humidification device for solving the problem of secondary air pollution caused by the filter element being prone to breed bacteria due to moisture absorption in related technologies.

[0006] To achieve the above purpose, the embodiment of the present invention provides the following technical solutions:

[0007] An embodiment of the present invention provides an air purification and humidification device, which includes an air purification device and an air humidification device connected thereto; the air purification device has an air inlet and an air outlet and is used for filtering air flow; the air humidification device includes a water storage container, an atomizing sheet and a humidifying cotton. The humidifying cotton is strip-shaped. The first end of the humidifying cotton is immersed in the liquid in the water storage container, and the second end of the humidifying cotton extends out of the water storage container; and the second end of the humidifying cotton extends into the air purification device and reaches the air outlet; the atomizing sheet is connected to the second end of the humidifying cotton and is used for generating atomized steam.

[0008] In this way, the air purification device can filter foreign matters such as lint and dust in the air. The air humidification device can spray atomized steam into the air to increase the air humidity. The air purification device and the air humidification device can be started separately or simultaneously. The air humidification device includes a water storage container, a humidifying cotton and an atomizing sheet. The first end of the humidifying cotton extends into the water storage container and is immersed in the liquid. The humidifying cotton can absorb the liquid in the water storage container. The second end of the humidifying cotton is connected to the atomizing sheet, so that the atomizing sheet can always be in contact with the liquid and vibrate to generate atomized steam. And the second end of the humidifying cotton can extend into the air purification device and reach the air outlet, so that the atomized steam sprayed by the atomizing sheet can directly disperse at the air outlet, without causing the filter element to be affected by moisture and avoiding secondary air pollution.

[0009] The air purification and humidification equipment as described above, wherein the air purification device includes an air duct shell, an air flow channel is provided in the air duct shell, one end of the air flow channel is connected to the air inlet, and the other end of the air flow channel forms the air outlet; the humidification cotton is inserted into the air flow channel.

[0010] The air duct shell forms an air flow channel for air flow to flow through, and the humidifying cotton is inserted into the air flow channel to extend to the air outlet, thereby preventing the humidifying cotton from extending from the outside of the air purification and humidification device, and the structure is compact.

[0011] The air purification and humidification equipment as described above, wherein the air purification device (10) further comprises a fan arranged in the air duct housing, and the humidification cotton is located between the circumferential outer edge of the fan and the inner wall surface of the air duct housing.

[0012] A flow channel for air flow is formed between the outer edge of the fan in the circumferential direction and the inner wall surface of the air duct shell. The humidifying cotton support member will not interfere with the fan when passing through the flow channel, and the structure is compact.

[0013] As described above, in the air purification and humidification device, the cross-sectional area of ​​the air duct shell gradually increases along the flow direction of the air flow to conform to the trend of the air flow gradually diffusing after being thrown out by the fan, thereby reducing the noise when the air flow collides with the air duct shell.

[0014] As described above, the air purification and humidification device, wherein the air duct shell is provided with a first opening for the humidification cotton to pass through, and the first opening can be set at different positions according to the shape of the air duct shell. When the cross-sectional area of ​​the air duct shell is gradually changed, the first opening can penetrate the side wall of the air duct shell, so that the humidification cotton can extend from the outside of the air duct shell to the inside of the air duct shell.

[0015] The air purification and humidification equipment as described above, wherein the air purification device further comprises a filter element, the filter element is used to filter the airflow flowing into the air duct housing, and the filter element has a second opening for the humidification cotton to pass through.

[0016] The filter is used to filter foreign matter such as hair and dust in the airflow, so that the clean airflow after filtering enters the air duct housing to achieve the purpose of purifying the air. Since the filter is arranged on the side of the air duct housing close to the air inlet, the filter is also provided with a second opening for the humidifying cotton to pass through.

[0017] In the air purification and humidification device as described above, the air duct housing is provided with a connection portion perpendicular to the extension direction of the air duct housing, and the filter element is connected to a side of the connection portion away from the air outlet.

[0018] The connecting part can reduce the port size at one end of the air duct housing close to the air inlet, thereby reducing the air flow entering the air duct from outside the fan air holes and reducing the operating noise of the air purification and humidification device.

[0019] For the air purification and humidification device as described above, a first filter seal is provided between the filter element and the connecting part to prevent unfiltered air flow from entering the air duct through the gap between the filter element and the connecting part.

[0020] For the air purification and humidification device as described above, the filter element has a flow-through cavity with openings at both ends. One opening of the flow-through cavity communicates with the air flow channel, and the other port of the filter element is closed by the water storage container. The circumferential side surface of the filter element forms the air inlet for the air flow to enter; the second opening penetrates the filter element along the extending direction of the flow-through cavity.

[0021] The flow-through cavity inside the filter element is equivalent to increasing the volume of the air duct housing, increasing the air volume of the air purification device, and having a good filtering effect.

[0022] For the air purification and humidification device as described above, a second filter seal is provided between the filter element and the water storage container to prevent unfiltered air flow from entering the air duct through the gap between the filter element and the water storage container.

[0023] For the air purification and humidification device as described above, the air purification device further includes an air outlet grille connected to the air duct housing, and the air outlet grille is arranged at the air outlet; the atomizing sheet is connected to the air outlet grille, and the atomized steam generated by the atomizing sheet can be ejected from the air duct housing through the air outlet grille.

[0024] In this way, the air outlet grille can protect components such as the fan in the air duct housing from being impacted by foreign objects. At the same time, the air outlet grille can also be used as a support component to separate from the atomizing sheet, enabling the atomized steam ejected by the atomizing sheet to be ejected through the air outlet grille.

[0025] For the air purification and humidification device as described above, the air humidification device further includes a humidifying cotton support member that surrounds the humidifying cotton, and one end of the humidifying cotton support member extends into the water storage container, and the other end of the humidifying cotton support member extends to the air outlet, and the atomizing sheet is connected to the other end of the humidifying cotton support member.

[0026] In this way, the humidifying cotton support member can support the humidifying cotton, preventing the humidifying cotton from moving relative to the atomizing sheet, resulting in the separation of the humidifying cotton from the atomizing sheet and the inability of the air humidification device to generate atomized steam.

[0027] The air purification and humidification device as described above, wherein the air purification and humidification device includes a housing surrounding the outside of the air duct housing, and the housing is snap-connected to the air humidification device.

[0028] In this way, the housing can protect the air purification device, and the housing is snap-connected to the air humidification device, facilitating the disassembly and assembly of the air purification device.

[0029] The air purification and humidification device as described above, wherein the air purification and humidification device further includes a base, and the base is rotatably connected to the air purification device or the air humidification device, so that the user can adjust the outlet direction of the air purification device according to needs, which is convenient to use.

[0030] In addition to the technical problems solved by the embodiments of the present invention described above, the technical features constituting the technical solutions, and the beneficial effects brought by these technical features of the technical solutions, the other technical problems that the air purification and humidification device provided by the embodiments of the present invention can solve, the other technical features included in the technical solutions, and the beneficial effects brought by these technical features will be further described in detail in the specific implementation manner.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0086] To avoid the humidity of the filter element increasing and causing bacteria to breed, the embodiments of the present application consider arranging the air humidifying device and the air purifying device side by side, so that the atomized steam generated by the air humidifying device can be directly discharged into the air, avoiding the filter element from getting damp and increasing in humidity, resulting in the growth of bacteria on the filter element.

[0088] Please refer to Figures 1 to 13 , this embodiment provides an air purification and humidification device, which can be a large device set on the ground for purifying and humidifying the air in a room, or a small device placed on a desktop, such as a desk. This embodiment takes the small air purification and humidification device as an example for illustration.

[0089] The air purification and humidification device includes an air purification device 10 and an air humidification device 20. The air purification device 10 is used to purify the air, and the air humidification device 20 is used to humidify the air. The air purification device 10 and the air humidification device 20 can be started separately to purify or humidify the air, or the air purification device 10 and the air humidification device 20 can be started simultaneously to purify and humidify the air at the same time.

[0090] Among them, the air purification device 10 is provided with an air inlet X and an air outlet Y. The airflow to be filtered can enter the air purification device 10 from the air inlet X, and after being filtered by the air purification device 10, it is discharged through the air outlet Y.

[0091] In some embodiments, the air purification device 10 may include a duct housing 11 and a fan 12 provided in the duct housing 11.

[0092] The duct housing 11 can be a cylindrical structural member, and an air flow channel for the airflow to flow through is formed inside it; and both ends of the duct housing 11 are respectively communicated with the air inlet X and the air outlet Y to introduce or discharge the airflow. The material of the duct housing 11 can be metal, which has high strength and long service life, and the material of the duct housing 11 can also be materials such as plastic, which has a small weight.

[0093] Considering that the air purification and humidification device is a small device, the duct housing 11 can be a straight cylinder type, that is, the duct housing 11 does not have a bent section. Among them, the duct housing 11 has a first port 111 and a second port 112. The first port 111 is communicated with the air inlet X, and the second port 112 can form the air outlet Y. The central connection line of the first port 111 and the second port 112 is parallel to the extension direction of the duct housing 11, reducing the impact loss of the airflow in the duct housing 11.

[0094] The fan 12 is provided in the duct housing 11. The fan 12 includes a motor 121 and a fan 122. When the motor 121 starts, it can drive the fan 122 to rotate, forming a negative pressure in the duct housing 11, so that the airflow enters the duct housing 11 from the first port 111 and flows out from the second port 112. The motor 121 can be of the types well-known to those skilled in the art.

[0095] The fan 122 can be an axial flow fan, a centrifugal fan, etc. Optionally, the fan 122 in this embodiment can be a centrifugal fan, and the air volume of the air flow conveyed by the centrifugal fan is relatively large. At this time, the axial direction of the centrifugal fan can be parallel to the extending direction of the air duct housing 11, that is, the central connection line of the two ports of the air duct housing 11 is also parallel to the axial direction of the centrifugal fan. When the centrifugal fan rotates, it can suck in the air flow along the axial direction of the centrifugal fan and then use the centrifugal force to throw the air flow out radially from the centrifugal fan. Subsequently, the air flow collides with the inner wall surface of the air duct housing 11, turns, and flows along the extending direction of the air duct housing 11 until it flows out from the air outlet Y.

[0096] Among them, the fan 122 can include a plurality of blades 1221 arranged at intervals along its circumferential direction and a guide vane 1222 connecting the plurality of blades 1221. The blades 1221 can be backward inclined, forward inclined or radially arranged. In this embodiment, the backward inclined blades 1221 are taken as an example for illustration, and they can convey a relatively large air flow rate.

[0097] The guide vane 1222 is arranged on the side of the blade 1221 close to the air inlet X. The guide vane 1222 is annular, and the air flow holes c formed on the guide vane 1222 are used for the air flow to pass through. When the fan 122 rotates, the air flow passes through the air flow holes c on the guide vane 1222 and then enters the space enclosed by the plurality of blades 1221 along the axial direction of the fan 12. Pushed by the blades 1221, the air flow is thrown out radially from the fan 122 under the action of the centrifugal force.

[0098] There is a spacing between the fan 122 and the air duct housing 11 to prevent the fan 122 from colliding and interfering with the air duct housing 11 when it rotates. For example, the spacing between the outer edge in the radial direction of the blade 1221 and the inner wall surface of the air duct housing 11 forms a flow passage 16 for the air flow thrown out from the fan 122 to flow toward the air outlet Y side.

[0099] It can be understood that there is also a spacing between the end of the fan 122 close to the air inlet X and the inner wall surface of the air duct housing 11. However, when the air flow enters the air duct housing 11 from this spacing, that is, when the air flow enters the air duct housing 11 from the outside of the air flow hole c, noise will be generated. To reduce the noise of the air purification device 10, in some embodiments, there can be a noise reduction gap 17 between the inner wall surface of the air duct housing 11 at the end close to the air inlet X and the end of the fan 122 close to the air inlet X.

[0100] As can be seen from the above embodiments, the fan 122 is provided with a guide vane 1222, and the side surface of the guide vane 1222 on the side close to the air inlet X of the air duct housing 11 is the end surface of the fan 122 close to the air inlet X.

[0101] In some embodiments, the air duct housing 11 may include an air duct body 114 and a connecting portion 115; both the fan 122 and the motor 121 are located within the air duct body 114. The extending direction of the connecting portion 115 is perpendicular to the extending direction of the air duct housing 11, and the first port 111 is formed in the connecting portion 115 in the shape of a hole. That is, the aperture of the first port 111 is reduced to be equal to or slightly larger than the aperture of the air flow hole c, reducing the air flow rate entering the air duct housing 11 from the outside of the air flow hole c.

[0102] In this way, a noise reduction gap 17 can be formed between the air guiding plate 1222 and the connecting portion 115. The gap value can be 1 mm - 3 mm. With a relatively small gap value, it neither affects the rotation of the fan 122 nor reduces the gas flow rate flowing through the noise reduction gap 17, thereby reducing the noise of the air purification device 10.

[0103] In some embodiments, the air guiding plate 1222 may include a first folded edge a extending radially along the axis of the fan 122 and a second folded edge b extending axially along the axis of the fan 122. The first folded edge a is used to connect with a plurality of blades 1221, and the second folded edge b encloses the above-mentioned air flow hole c for the air flow to pass through.

[0104] Among them, the first folded edge a is parallel to the inner wall surface of the connecting portion 115 and is located within the air duct housing 11. Please refer to Figure 5 When the second folded edge b is located within the air duct housing 11, the distance between the first folded edge a and the inner wall surface of the connecting portion 115 can be greater than the extending length of the second folded edge b. The gap between the end of the second folded edge b facing away from the first folded edge a and the inner wall surface of the connecting portion 115 is small, which can reduce the air flow rate flowing through the noise reduction gap 17 and reduce the noise of the air purification device 10.

[0105] Optionally, the second folded edge b can also extend into the first port 111 formed by the connecting portion 115. At this time, the noise reduction gap 17 includes a portion between the second folded edge b and the inner wall surface of the first port 111 and a portion between the first folded edge a and the inner wall surface of the connecting portion 115. The extending length of the noise reduction gap 17 becomes larger, which also helps to reduce the air flow rate flowing through the noise reduction gap 17 and reduce the noise of the air purification device 10.

[0106] In some embodiments, along the air flow direction, the cross-sectional area of the air duct body 114 can gradually increase. The small port of the air duct body 114 is the first port 111 and can be connected to the connecting portion 115. The large port of the air duct body 114 is the second port 112 and forms an air outlet Y. Exemplarily, the inner wall surface of the air duct body 114 can be smoothly transitioned in an arc shape to conform to the trend of the air flow gradually diffusing after being thrown out by the fan 122, reducing the impact noise when the air flow diffuses against the air duct body 114.

[0107] It can be understood that the motor 121 is also arranged inside the air duct housing 11 and connected to the fan 122. To prevent the airflow from impacting the motor 121, the motor 121 can be arranged on the side of the fan 122 close to the air outlet Y of the air duct housing 11. A connecting plate 1223 can be arranged on the side of the fan 122 close to the air outlet Y of the air duct housing 11, and the connecting plate 1223 connects the plurality of blades 1221 and is used to connect to the motor 121.

[0108] During the flow of air, the air first enters the space surrounded by the multiple blades 1221 along the axial direction of the fan 122, and then the air is subjected to centrifugal force and is thrown out of the fan along the radial direction of the fan 122. That is, the airflow distribution at one end close to the air outlet Y in the space surrounded by the multiple blades 1221 is less. In this way, the portion of the connecting plate 1223 corresponding to the space can protrude toward the side of the air inlet X and form a receiving chamber d, and part of the motor 121 can be arranged in the receiving chamber d to reduce the space of the air duct housing 11 occupied by the motor 121, the length of the air duct housing 11 becomes smaller, the size of the air purification device 10 using the air duct housing 11 becomes smaller, and the size of the air purification and humidification equipment will also be correspondingly reduced.

[0109] Furthermore, the air purification device 10 also includes a motor fixing seat 123 for fixing the motor 121 in the air duct housing 11. The motor fixing seat 123 may include a plate-shaped fixing seat body 1231, and may be connected to the motor 121 by fasteners such as bolts. In order to reduce the resistance of the motor fixing seat 123 to the airflow, the fixing seat body 1231 may be provided with a plurality of connecting strips 1232 at intervals in the circumferential direction, and the connecting strips 1232 are correspondingly arranged in the circulation channel 16. The connecting strips 1232 and the air duct housing 11 may also be connected by fasteners such as bolts, which are easy to disassemble and reliably connected.

[0110] A reinforcement structure may be provided on the fixing seat body 1231 to increase the anti-deformation strength of the fixing seat body 1231. Exemplarily, the fixing seat body 1231 may be in the shape of a groove, and the opening of the fixing seat body 1231 in the shape of a groove may face the side of the motor 121, that is, the end of the motor 121 away from the fan 122 may extend into the groove, and since the air flow distribution at the end close to the air outlet Y in the space surrounded by the plurality of blades 1221 is less, the influence of the fixing seat body 1231 in the shape of a groove on the air flow may be ignored.

[0111] In some embodiments, in order to protect the motor 121, fan 122 and other components in the air duct housing 11, an air outlet grille 14 and an air inlet grille 15 may be respectively provided at two ports of the air duct housing 11 to avoid collision with foreign objects.

[0112] The air outlet grille 14 can be detachably connected to the air duct housing 11 by means of snap connection between the buckle and the card slot, so as to repair the fan 122 and the motor 121 by disassembling the air outlet grille 14, which is convenient to use. The part of the air outlet grille 14 corresponding to the fixed seat body 1231 can also be a plate-like structure with high strength; the part of the air outlet grille 14 corresponding to the flow channel 16 can be provided with air outlet grille bars, and the air flow can flow out of the air duct housing 11 through the gaps between two adjacent air outlet grille bars.

[0113] Among them, the air inlet grille 15 can be integrally formed with the air duct housing 11, reducing the number of forming molds and having low manufacturing cost. The air inlet grille 15 includes a plurality of air inlet grille bars, and the air flow can enter the air duct housing 11 through the gaps between two adjacent air inlet grille bars.

[0114] The air outlet grille bars and the air inlet grille bars can be of types well-known to those skilled in the art, and the number and spacing thereof are not limited in this embodiment.

[0115] It can be understood that the inner wall surface of the air duct housing 11, the motor 121, the fan 122, as well as the air outlet grille 14 and the air inlet grille 15 will all form obstacles to the flow of the air flow. During the flow of the air flow, the air flow is subject to the frictional resistance of the above components, and the air pressure and flow rate of the air flow will decrease. To prevent the reduction amount of the air pressure and flow rate of the air flow from exceeding the preset range, the windward edge of the air inlet grille bars, the connecting bars 1232 and the air outlet grille bars can all be provided with a chamfered structure to form a guiding effect on the air flow and prevent the air pressure and flow rate of the air flow from being significantly reduced.

[0116] In some embodiments, the air purification device 10 further includes a filter element 13, and the filter element 13 can be disposed at the air inlet X of the air duct housing 11 for filtering foreign matters such as lint and dust in the air. Optionally, the filter element 13 in this embodiment can be disposed outside the air duct housing 11 and at the first port 111, so that the air flow entering the air duct housing 11 is filtered by the filter element 13, preventing foreign matters from accumulating on the inner wall surface of the air duct housing 11 or the fan 12 and affecting the service life.

[0117] The filter element 13 can be a filter net. Considering that the filter element 13 is disposed at the first port 111 and the distance between the filter element 13 and the first port 111 is small, the filter element 13 can also be a cylindrical structure. A flow cavity for the air flow to flow through is formed inside the cylindrical filter element 13, and the air duct housing 11 communicates with the flow cavity. Exemplarily, the axis of the first port 111 can coincide with the axis of the cylindrical filter element 13, and the caliber of the first port 111 is less than or equal to the cross-sectional dimension of the flow cavity, so that the first port 111 can be located inside the flow cavity.

[0118] At this time, one end face of the cylindrical filter element 13 is mounted on the side of the connecting portion 115 facing away from the air outlet Y. The circumferential side surface of the cylindrical filter element 13 forms an air inlet X for the inflow of air. The air flows into the flow cavity of the cylindrical filter element 13 after being filtered by the filter element 13, and then enters the air duct housing 11. Both the filter net and the cylindrical filter element 13 can be of types well-known to those skilled in the art. For example, it can be a High Efficiency Particulate Air Filter (HEPA), that is, a filter net meeting the HEPA standard.

[0119] The cylindrical filter element 13 can include a filter body and end caps provided at both ends of the filter body. The end caps can protect the filter body and can be used to connect to the connecting portion 115 and the air humidifying device 20.

[0120] A first filter seal 132 is provided at the joint surface between the connecting portion 115 and the cylindrical filter element 13. The first filter seal 132 can be a rubber gasket well-known to those skilled in the art to prevent unfiltered air from entering the air duct housing 11.

[0121] The air inlet grille 15 can be in the shape of a plate and is in the same plane as the connecting portion 115. In some embodiments, the air inlet grille 15 can also protrude from the connecting portion 115 towards one side of the filter element 13 and is snap-connected to the inner wall surface of the cylindrical filter element 13 to position the filter element 13.

[0122] In some embodiments, the air purification device 10 further includes a protective grille 2131 surrounding the filter element 13. The protective grille 2131 can be connected to the air duct housing 11 or to the air humidifying device 20. The protective grille 2131 is used to prevent large foreign objects from hitting the filter element 13 or to prevent sheet-like foreign objects from adhering to the circumferential side surface of the filter element 13, affecting the inflow of air. The protective grille 2131 includes a plurality of protective grille bars 2131, and the number and spacing of the protective grille bars 2131 can be set as needed.

[0124] Please refer to Figure 5 and Figures 14 to 24 , the air humidifying device 20 can be arranged on the side of the cylindrical filter element 13 away from the air duct housing 11. The air humidifying device 20 can include a water storage container 21, an atomizing sheet 22 and a humidifying cotton 23.

[0125] The water storage container 21 is a hollow structural member for storing water. The water storage container 21 can be in contact with the end face of the filter element 13 away from the air duct housing 11. And in order to prevent the air flow that has not been filtered by the filter element 13 from entering the air duct housing 11, a second filter seal 133 can be arranged between the water storage container 21 and the filter element 13. The structure of the second filter seal 133 can be the same as that of the first filter seal 132, and both are structures well-known to those skilled in the art, such as rubber gaskets.

[0126] The water storage container 21 can be in the structure of a cube, a sphere, etc. The material of the water storage container 21 can be metal, plastic, etc., and this embodiment does not limit it.

[0127] The atomizing sheet 22 can be a microporous atomizing sheet well-known to those skilled in the art, etc. Atomized steam is generated through the oscillation of the microporous atomizing sheet.

[0128] During the process that the atomizing sheet 22 oscillates to generate atomized steam, water is continuously consumed and the water level drops. The atomizing sheet 22 cannot be in contact with water for a long time. Therefore, the air humidifying device 20 can further include a humidifying cotton 23.

[0129] The material of the humidifying cotton 23 can be cellulose acetate (CA), which has a low cost and is easy to be woven and manufactured into strip-shaped, plate-shaped and other structures. Since the size of the atomizing sheet 22 is small, in this embodiment, the strip-shaped humidifying cotton 23 is taken as an example for illustration. One end face of the humidifying cotton 23 can be in contact with the atomizing sheet 22.

[0130] The humidifying cotton 23 has many pores and strong water absorption. When one end of the humidifying cotton 23 is immersed in water, the humidifying cotton 23 can absorb water until the humidifying cotton 23 is in a soaked state. The atomizing sheet 22 is in contact with the humidifying cotton 23. As long as the humidifying cotton 23 is in contact with the water in the water storage container 21, the atomizing sheet 22 can always be in contact with the water, so that the atomizing sheet 22 can continuously generate atomized steam.

[0131] After the humidifying cotton 23 absorbs water, its gravity increases. Under the action of its own gravity, the humidifying cotton 23 may move relative to the water storage container 21, causing the humidifying cotton 23 to separate from the atomizing sheet 22, and the atomizing sheet 22 cannot generate atomized steam. In some embodiments, the air humidifying device 20 also includes a humidifying cotton support 24, on which the humidifying cotton 23 is arranged, and the humidifying cotton support 24 is connected to the water storage container 21, so that the humidifying cotton 23 can be prevented from moving relative to the water storage container 21 and the humidifying cotton 23 can be prevented from being separated from the atomizing sheet 22.

[0132] The humidifying cotton support 24 can be a clamping spring, which is sleeved outside the humidifying cotton 23. One end of the clamping spring is connected to the water storage container 21, and the other end of the clamping spring is used to support the humidifying cotton 23 to prevent the humidifying cotton 23 from falling out.

[0133] Optionally, the humidifying cotton support member 24 in this embodiment may be a tubular structure, and the humidifying cotton 23 is accommodated inside the tubular humidifying cotton support member 24. The tubular humidifying cotton support member 24 may be made of polyvinyl chloride (PVC) and other materials, and may be immersed in water for a long time without deterioration or generation of impurities such as debris.

[0134] The humidifying cotton support 24 may include a water absorbing section 241 and a connecting section 242. The water absorbing section 241 is used to extend into the water storage container 21. A plurality of penetrating water holes 2412 are provided on the tube wall of the water absorbing section 241. When water is stored in the water storage container 21, the water holes 2412 may allow the water in the water storage container 21 to enter the water absorbing section 241, so that the humidifying cotton 23 in the water absorbing section 241 may absorb water. The water absorbing holes 2412 may be rectangular holes, circular holes, or any other shapes.

[0135] To prevent the humidifying cotton 23 from falling out, the cross-sectional area of ​​the water absorbing section 241 can be gradually reduced toward the end away from the connecting section 242, and the humidifying cotton 23 is pressed tightly in the water absorbing section 241, that is, the inner wall surface of the water absorbing section 241 forms a blocking portion 2411 to prevent the humidifying cotton 23 from falling out.

[0136] The blocking portion 2411 may also be a baffle or a baffle bar formed at the end of the water absorption section 241 away from the connecting section 242. In this case, the water absorption section 241 may be a tubular structure of equal cross-section. After the humidifying cotton 23 is extended into the humidifying cotton 23 support member, one end of the humidifying cotton 23 abuts against the blocking portion 2411, and the other end extends out of the connecting section 242, so that the humidifying cotton 23 extending out of the connecting section 242 can be slightly deformed and abut against the atomizing sheet 22, so that the atomizing sheet 22 can come into contact with water.

[0137] According to the shape of the water storage container 21, the water absorption section 241 can be in the shape of a straight rod or bent into a curved rod. For example, when the water storage container 21 has a spherical arc wall, the end of the water absorption section 241 away from the connecting section 242 can be bent and extended toward the side of the connecting section 242, that is, the water absorption section 241 is in the shape of an arc rod and fits with the spherical arc wall of the water storage container 21, thereby increasing the length of the water absorption section 241 in contact with water, which facilitates the humidification cotton 23 to absorb water.

[0138] The connecting section 242 is used to connect with the water storage container 21. For example, the connecting section 242 can be welded or bonded to the water storage container 21. In this embodiment, the connecting section 242 can be snap-fitted with the water storage container 21 to enable the humidification cotton support 24 to be disassembled and the humidification cotton 23 to be replaced.

[0139] At this time, the water storage container 21 may have a through-mounting hole e. The atomizing sheet 22 may be disposed in the mounting hole e, the humidifying cotton support 24 may extend into the water storage container 21 through the mounting hole e, and the connecting section 242 may be snap-fitted with the inner wall surface of the water storage container 21 or with the hole wall surface of the mounting hole e. Exemplarily, a snap-fitting flange 2421 may be disposed on the connecting section 242, a snap-fitting groove may be disposed on the hole wall surface of the mounting hole e, and the snap-fitting flange 2421 may be accommodated in the snap-fitting groove.

[0140] In order to facilitate the placement or removal of the humidifying cotton support 24, the hole area of ​​the mounting hole e can be larger than the cross-sectional area of ​​the humidifying cotton support 24. For example, the mounting hole e can be a strip-shaped hole, and the cross-sectional shape of the humidifying cotton support 24 is circular, and its outer diameter is smaller than the width of the strip-shaped hole. In this embodiment, the air humidifying device 20 can also include a cover 25 that closes the mounting hole e. The cover 25 can be detachably connected to the water storage container 21, such as by snapping or connecting through a threaded fastener, so as to facilitate the disassembly and assembly of the cover 25.

[0141] The cover 25 is provided with a connection hole 251 connected to the connection section 242, and for example, a snap-fit ​​groove can be provided on the inner wall surface of the connection hole 251. In some embodiments, the snap-fit ​​flange 2421 can contact the inner wall surface of the connection hole 251, and the edge of a portion of the mounting hole e is exposed in the connection hole 251, and the snap-fit ​​flange 2421 can overlap the end surface of the mounting hole e.

[0142] Considering that the user may move the air purification and humidification device, an elastic shock absorber 26, such as an elastic rubber pad or a compression spring, may be provided between the clamping flange 2421 and the end face of the mounting hole e. Correspondingly, an anti - detachment flange 2511 for preventing the humidifying cotton support member 24 from coming out is provided on the connecting hole 251. The clamping flange 2421 abuts against the anti - detachment flange 2511 under the elastic force of the elastic shock absorber 26. A shock - absorbing gasket or the like may also be provided between the anti - detachment flange 2511 and the clamping flange 2421 to avoid the rigid impact on the humidifying cotton support member 24.

[0143] Further, a cover seal 252 may be provided at the joint between the cover 25 and the water storage container 21 to prevent water leakage between the cover 25 and the water storage container 21. Exemplarily, an annular groove surrounding the mounting hole e may be provided on the outer wall surface of the water storage container 21, and an annular boss inserted into the annular groove is provided on the cover 25. The cover seal 252 may be provided in the annular groove. When the annular boss is inserted into the annular groove, the cover seal 252 is deformed under pressure and abuts against the inner wall surface of the annular groove to form a seal, avoiding water leakage between the cover 25 and the water storage container 21 when handling or turning over the air purification and humidification device. The cover seal 252 may be a rubber ring or the like well - known to those skilled in the art.

[0144] In some embodiments, to prevent the atomized steam generated by the air humidifying device 20 from flowing through the interior of the air purification device 10, the atomizing sheet 22 may be provided at the air outlet Y of the air purification device 10. For example, the atomizing sheet 22 may be provided on the air outlet grille 14. In this way, when the air purification device 10 is shut down and the air humidifying device 20 is operating, the atomized steam ejected by it can disperse at the air outlet Y of the air purification device 10. Or when the air humidifying device 20 and the air purification device 10 are operating simultaneously, the atomized steam generated by the air humidifying device 20 can be blown away by the airflow flowing out through the air outlet Y of the air purification device 10, avoiding the filter element 13 from getting damp and breeding bacteria and also avoiding secondary air pollution.

[0145] At this time, the connecting section 242 can extend out of the water storage container 21 through the mounting hole e. Considering that the humidifying cotton support member 24 is a tubular structure and is prone to skew deformation when its length increases, the air humidifying device 20 may further include a fixing assembly 27 for stabilizing the humidifying cotton support member 24 to prevent the humidifying cotton support member 24 located outside the water storage container 21 from being skewed and deformed.

[0146] The fixing component 27 includes a sleeve 271 and a pressing member 272. The sleeve 271 is sleeved on the connecting section 242 extending out of the water storage container 21. One end of the sleeve 271 is connected to the cover 25, and the other end of the sleeve 271 is connected to the pressing member 272. Among them, the atomizing sheet 22 can be mounted on the end face of the other end of the sleeve 271, and the pressing member 272 is buckled on the atomizing sheet 22 and connected to the sleeve 271 to fix the atomizing sheet 22. The pressing member 272 is provided with a through hole 2721 that can expose the atomizing sheet 22, so that the atomized steam generated by the atomizing sheet 22 can be ejected through the through hole 2721.

[0147] Among them, the pressing member 272 can be detachably connected to the sleeve 271, such as by snap connection or bolt connection, which is convenient for disassembly to repair and replace the atomizing sheet 22.

[0148] As can be seen from the above embodiments, the humidifying cotton 23 extends out of the humidifying cotton support member 24 and abuts against the atomizing sheet 22. At this time, the atomizing sheet 22 is mounted on the end face of the sleeve 271, that is, there is a step difference between the end face of the humidifying cotton support member 24 and the end face of the sleeve 271.

[0149] When the air humidifying device 20 is working, water droplets may condense at the atomizing sheet 22. The water droplets can accumulate in the gap formed by the step difference and flow along the gap between the sleeve 271 and the humidifying cotton support member 24. To prevent water leakage at the connection between the sleeve 271 and the cover 25, a sleeve seal 2711 can also be provided at the joint between the sleeve 271 and the cover 25, so that the water droplets can continue to flow back into the water storage container 21 through the gap between the cover 25 and the humidifying cotton support member 24.

[0150] In some embodiments, the water storage container 21 can include a container body 212 and a container cover 213. The container body 212 and the container cover 213 can be fixedly connected, such as by ultrasonic welding, with good sealing performance to prevent water leakage in the water storage container 21.

[0151] The end face of the filter element 13 facing away from the air duct housing 11 can be connected to the container cover 213. At this time, the protective grille 2131 surrounding the filter element 13 can be integrally formed with the container cover 213, reducing the number of molding dies for parts and having a low manufacturing cost.

[0152] The water storage container 21 is provided with a water filling port f for adding water and a water filling cap 214 for closing the water filling port f. The water filling cap 214 is detachably connected to the container cover 213, such as by threading, snap connection, etc. A water filling seal can also be provided between the water filling cap 214 and the water filling port f.

[0153] The water filling port f can be provided on the container body 212. Optionally, the water filling port f can also be provided at a position corresponding to the flow cavity of the container cover 213 and the filter element 13, so that the air purification and humidification device can have no water filling port in appearance, simplifying the appearance structure of the air purification and humidification device.

[0155] Please refer to Figure 8 and Figures 26 to 33 , in order to add water to the water storage container 21, the filter element 13 needs to be removed, that is, the air purification device 10 and the air humidification device 20 can be detachably connected. In this embodiment, the air purification and humidification device further includes a housing 30 surrounding the air duct housing 11. The housing 30 can be provided with a plug-in block 304, and a plug-in slot 116 is provided on the outer wall surface of the air duct housing 11. The positioning and fixing of the air duct housing 11 and the housing 30 are realized by the clamping of the plug-in block 304 and the plug-in slot 116. And the housing 30 is also detachably connected to the container body 212 of the water storage container 21.

[0156] Specifically, an elastic hook 2133 can be provided on the protective grille 2131 or the container body 212. One end of the elastic hook 2133 is connected to the protective grille 2131, and the other end is a free end. Correspondingly, a clamping portion 31 that can be hooked with the elastic hook 2133 can be provided on the housing 30.

[0157] Among them, the housing 30 includes an ear portion 301 extending toward the air humidification device 20 and a fastening member 34 that is fastened to the ear portion 301. The fastening member 34 is provided inside the ear portion 301. The fastening member 34 is detachably connected to the ear portion 301 and encloses a clamping cavity.

[0158] The ear part 301 is provided with a through button hole 302, and along the circumferential direction of the button hole 302, a plurality of sliding grooves 303 are provided on the inner wall surface of the ear part 301. The sliding grooves 303 extend radially inward towards the fan 122. A corresponding sliding part 321 is provided on the circumferential direction of the button 32. The sliding part 321 is inserted into the sliding groove 303 and can reciprocate along the length direction of the sliding groove 303.

[0159] The button 32 is further provided with a top abutting part 322 located in the clamping cavity. A clamping hole 341 is provided at the position corresponding to the top abutting part on the fastening part 34. The clamping hole 341 penetrates through the fastening part 34. A part of the inner wall surface of the clamping hole 341 can form a clamping part 31. Exemplarily, the side surface of the clamping hole 341 facing away from the air purification device 10 can be hooked with the elastic hook 2133.

[0160] A return spring 33 is sleeved outside the top abutting part 322 and is pressed between the button 32 and the fastening part 34. Under the elastic force of the return spring 33, the button 32 makes the sliding part 321 abut against the sliding groove 303, preventing the button 32 from coming out. At this time, the outer wall surface of the button 32 and the outer wall surface of the ear part 301 have a smooth transition.

[0161] When the user presses the button 32, the distance between the button 32 and the fastening part 34 becomes smaller, and the return spring 33 is compressed. At this time, the top abutting part 322 passes through the clamping hole 341 and pushes the elastic hook 2133 until the elastic hook 2133 disengages from the clamping part 31.

[0162] When the user releases the button 32, the button 32 moves under the elastic force of the return spring 33 until the sliding part 321 abuts against the sliding groove 303.

[0163] When installing the air purification device 10 and the air humidifying device 20, the air purification device 10 can be directly moved towards one side of the air humidifying device 20. The elastic hook 2133 will move towards the side away from the clamping part 31 under the abutting action of the clamping part 31 until the elastic hook 2133 can be hooked with the hook part 31.

[0164] It can be understood that the clamping part 31 and the elastic hook 2133 are in one-to-one correspondence, and two groups or more groups of air purification and humidifying devices can be provided.

[0165] Please continue to refer to Figures 2 to Figure 24 , to further simplify the appearance structure of the air purification and humidifying equipment, the humidifying cotton support 24 can also be arranged inside the air purification and humidifying equipment, that is, the installation hole e is arranged on the container cover 213, the cover 25 is connected to the container cover 213, the humidifying cotton support 24 is connected to the cover 25, and the filter element 13 is arranged in a fitting manner with the container cover 213. Then, in order to arrange the atomizing sheet 22 at the air outlet Y, the humidifying cotton support 24 can pass through the air purification and humidifying device.

[0166] Among them, the filter element 13 may be provided with a second opening 131 penetrating along its own axis for the humidifying cotton support member 24 to pass through. Optionally, the second opening 131 may also penetrate the side wall of the filter element 13 along the radial direction of the filter element 13, reducing the manufacturing cost of the filter element 13.

[0167] At this time, the cover 25 may also be located within the second opening 131. Specifically, the cover 25 may include a cover plate body 253 and a connecting pipe body 254. The connecting pipe body 254 protrudes from the cover plate body 253 toward the air duct housing 11, and the connecting hole 251 is formed within the connecting pipe body 254. The above-mentioned annular boss is provided on the side surface of the cover plate body 253 facing away from the connecting pipe body 254. The connecting pipe body 254 protrudes relative to the cover 252, which can increase the length of the connecting hole 251 and can form support and limitation for the humidifying cotton support member 24 passing through the connecting hole 251.

[0168] Among them, the protruding height of the connecting pipe body 254 may be less than or equal to the height of the filter element 13 to avoid interference between the connecting pipe body 254 and the air duct housing 11.

[0169] One end of the sleeve 271 close to the cover 25 may be sleeved outside the connecting pipe body 254, so that the sleeve seal 2711 may be provided between the inner wall surface of the sleeve 271 and the inner wall surface of the connecting pipe body 254. For example, a sealing groove for accommodating the sleeve seal 2711 may be provided on the outer wall surface of the connecting pipe body 254.

[0170] The container cover body 213 may be provided with a clamping plate 2132 that is clamped to the second opening 131. The clamping plate 3132 may be U-shaped and surround the cover 25. The 2132 of the U-shaped clamping plate includes two opposite side plates and a connecting plate connecting the two opposite side plates. The two opposite side plates extend along the radial direction of the filter element 13 and may be attached to the wall surface formed by the second opening 131 on the filter element 13, facilitating the positioning of the filter element 13. The connecting plate is arranged on the side of the side plate close to the flow cavity of the filter element 13. A through-hole seal may be provided between the U-shaped clamping plate 2132 and the filter element 13 to prevent unfiltered air from entering the air duct housing 11.

[0171] Furthermore, the air duct housing 11 is arranged on the side of the filter element 13 away from the water storage container 21. The air duct housing 11 has an air duct body 114 with a gradually increasing cross-sectional area. Then, the air duct body 114 has a first opening 113 for the humidifying cotton support member 24 to pass through. Since the sleeve 271 is sleeved outside the humidifying cotton support member 24, the sleeve 271 also passes through the first opening 113.

[0172] To avoid interference between the humidifying cotton support member 24 and the fan 122, the first opening 113 can be provided on one side of the air duct body 114 close to its side wall. After passing through the first opening 113, the humidifying cotton support member 24 extends to the air outlet Y of the air duct housing 11 through the flow channel 16 in the air duct housing 11.

[0173] The pressing member 272 can abut against the side surface of the air outlet grille 14 close to the air inlet. At this time, the atomized steam generated by the atomizing sheet 22 can be ejected through the gap between two adjacent air outlet grille bars.

[0174] In some embodiments, a third opening 141 can be provided on the air outlet grille 14. The pressing member 272 is snap-connected to the third opening 141, and the through hole 2721 on the atomizing sheet 22 communicates with the third opening 141, so that the atomized steam generated by the atomizing sheet 22 is ejected through the third opening 141 and diffused into the air.

[0175] The third opening 141 can be a stepped hole. The stepped hole includes a plugging section 1411 inserted into the pressing member 272 and a steam outlet section 1412 for ejecting atomized steam. The aperture of the steam outlet section 1412 can be smaller than that of the plugging section 1411, so that the stepped surface formed between the steam outlet section 1412 and the plugging section 1411 can abut against the pressing member 272 to limit the pressing member 272.

[0176] Since the water filling port f is provided inside the air purification and humidification device, when water needs to be added to the water storage container 21, the air purification device 10 needs to be disassembled. To avoid the need to align the pressing member 272 and the third opening 141 when installing the air purification device 10, in this embodiment, the sleeve 271 can be fixedly connected to the air duct housing 11, for example, detachably connected by a fastening bolt.

[0177] At this time, one end of the sleeve 271 sleeved with the connecting pipe body 254 extends outside the air duct housing 11, that is, the position where the sleeve 271 is connected to the connecting pipe body 254 is located in the second opening 131 of the filter element 13. In this way, when the air purification device 10 is disassembled, the sleeve 271, the pressing member 272 and the atomizing sheet 22 are all disassembled together with the air purification device 10. At this time, one end of the connecting pipe body 254 connected to the sleeve 271 is exposed to view, and the user can clean the accumulated water here. When installing the air purification device 10, it is only necessary to insert the humidifying cotton support member 24 into the sleeve, which is convenient to operate.

[0178] When water needs to be added to the water storage container 21 of the air humidifying device 20, the button 32 can be pressed to disconnect the connection between the housing 30 and the container body 212. By taking the housing 30, the housing 30, the air duct housing 11, the sleeve 271, the pressing member 272 and the atomizing sheet 22, etc. are disassembled from the air humidifying device 20 as a whole.

[0179] At this time, the filter element 13, the first filter seal 132, and the cover 25 are exposed to view, and the user can clean the accumulated water at the cover 25. Moreover, since the filter element 13, the first filter seal 132, and the second filter seal 133 are pressed and fixed by the air duct housing 11 and the water storage container 21, the user can directly take the filter element 13 and the first filter seal 132.

[0180] In this way, the water filling cap 214 and the second filter seal 133 are exposed to view, and the second filter seal 133 is arranged around the water filling cap 214. The user can directly open the water filling cap 214 without removing the second filter seal 133. After filling with water, place the water filling seal and tighten it through the water filling cap 214; place the filter element 13 and the first filter seal 132; then insert the humidifying cotton support 24 into the sleeve 271 until the housing 30 is snap-connected to the container body 212 to complete the water filling operation.

[0181] In some embodiments, to facilitate the quick assembly of the fixing component 27 onto the air duct housing 11, the pressing member 272, the atomizing sheet 22, and the sleeve 271 can be first connected as a whole, and then this whole is connected to the air duct housing 11. Among them, a positioning boss 2722 can be provided on the pressing member 272, and a positioning groove 117 is provided at the position of the air duct housing 11 corresponding to the positioning boss 2722. When the positioning boss 2722 is snap-connected into the positioning groove 117, the connection part between the sleeve 271 and the air duct housing 11 is aligned, which is convenient for operation.

[0182] Figure 34 It is a schematic diagram of the rotation of the air purification and dehumidification device. Please refer to Figure 34 , in some embodiments, the air purification and humidification device may further include a base 40, and the base 40 can play a supporting role, that is to say, the air purification and humidification device can also be supported by a component independent of the air purification device 10 and the air humidification device 20. Among them, the base 40 can be connected to the air purification device 10 or connected to the air humidification device 20, and this embodiment does not limit it.

[0183] Exemplarily, the base 40 can be rotatably connected to the water storage container 21, and its rotation axis can extend in the horizontal direction. The user can adjust the air outlet Y of the air purification device 10 to be in the horizontal direction, the vertical direction, or any other direction according to needs, which is convenient for use.
