Description

Technical Field

[0001] This invention relates to the field of air purifier technology, specifically to an air humidification and purification module, an air humidification and purifier, and an air conditioner. Background Technology

[0002] Currently, water-washing air purifiers generally include a rotating water jet. The basic principle of air purification is that the rotating water jet revolves around its axis, using centrifugal force to fling water through a water jet channel, forming a water curtain to purify the air flowing by. Rotating water jets generally come in two types: pump-suction and self-priming. The pump-suction type has a water pump connected to one end of the rotating tube, supplying water to the tube. The self-priming type uses the rotation of the conical tube to draw water into the tube and elevate it to the water jet channel.

[0003] In the prior art, invention patent application number 202220549283.5 discloses a filter element assembly and a device using the filter element assembly. The assembly includes a filter element assembly and a spray device disposed within it. The spray device acts as a rotating water jet to generate a water curtain for air purification. The filter element assembly, combined with the water entering it, filters the air. During air purification, the air first passes through the filter element assembly and then enters the annular space between the filter element assembly and the spray device, where it comes into contact with the water curtain before being filtered again and then discharged. The inventors have found that in this type of device, because the filter element assembly is stationary, the airflow entering the annular space after passing through it is relatively smooth and orderly. The airflow exits with a shorter path and time, resulting in a smaller contact time and area between the air and the water curtain, leading to poor purification effect and room for improvement. In addition, the inventors also discovered that in this device, since the air is filtered by the filter element assembly before contacting the water curtain, even if some water enters the filter element and filters the air through the water film, the filter element will still become clogged after long-term use and needs to be cleaned and replaced more frequently, indicating room for improvement. Summary of the Invention

[0004] One of the objectives of this invention is to design an air humidification and purification module, an air humidification and purifier, and an air conditioner to solve the problem of poor purification effect.

[0005] This invention is achieved through the following technical solution:

[0006] This invention provides an air humidification and purification module with a rotating axis and including an air filter, a rotating water-spraying body, and a driving device. The air filter includes a filter element peripheral wall formed around the rotating axis, capable of passing through and filtering air. The rotating water-spraying body is rotatably disposed inside the filter element peripheral wall, and a second annulus communicating with the outside and allowing air to pass through is formed between the peripheral wall of the rotating water-spraying body and the filter element peripheral wall. At least a portion of the water-spraying channels of the rotating water-spraying body are located inside the filter element peripheral wall. The driving device is connected to the air filter and the rotating water-spraying body, capable of driving the air filter to rotate around the rotating axis, and simultaneously driving the rotating water-spraying body to rotate in the opposite direction of rotation relative to the air filter's rotation axis. During the rotation of the rotating water-spraying body, water in at least a portion of the water-spraying channels located inside the filter element peripheral wall is thrown out towards the filter element peripheral wall under centrifugal force, forming a water curtain.

[0007] When the above-mentioned structure is adopted, the rotating water jet and the air filter are inner and outer sleeved and can be rotated in opposite directions by the drive device. This causes the air to generate a more turbulent airflow after passing through the air filter and entering the second ring air. This can prolong the path of the airflow in the second ring air to a certain extent and increase the time in the second ring air. This allows the air to have a longer contact time and a larger area with the water curtain in the second ring air, thereby improving the air purification effect.

[0008] To further improve the realization of the present invention, the following structure is specifically adopted: the rotation axis of the rotating water jet is coaxial with the rotation axis.

[0009] To further improve the implementation of this invention, the following structure is specifically adopted: the driving device is configured as a planetary gear transmission structure with a locked wheel frame; the sun gear of the planetary gear transmission structure is coaxially arranged and connected to the rotating water-throwing body, and the wheel rim of the planetary gear transmission structure is coaxially arranged and connected to the air filter element.

[0010] To further improve the implementation of the present invention, the following structure is specifically adopted: the peripheral wall of the filter element includes a frame and a core material installed on the frame, and one end of the frame is connected to the wheel rim.

[0011] To further improve the implementation of this invention, the following structure is specifically adopted: the wheel frame is provided with an exhaust channel; one end of the frame is connected to an exhaust pipe coaxially arranged therewith, the free end of the exhaust pipe is connected to the wheel rim, and the exhaust pipe connects the exhaust channel to the second annulus.

[0012] To further improve the implementation of this invention, the following structure is specifically adopted: the frame is detachably connected to the wheel rim via the exhaust pipe.

[0013] To further improve the implementation of this invention, the following configuration structure is adopted: the driving device can also be configured as a coaxial dual-output transmission structure, wherein the two output ends of the coaxial dual-output transmission structure are respectively connected to the air filter and the rotating water-throwing body.

[0014] To further improve the implementation of this invention, the following structure is specifically adopted: the rotating water-throwing body is configured as a pump-suction type rotating water-throwing body, and its inlet end is configured as a water pump.

[0015] To further improve the implementation of this invention, the following structure is specifically adopted: the rotating water-spraying body can also be configured as a self-priming rotating water-spraying body, which includes a water-absorbing conical tube with the rotation axis as the axis, the water inlet end of the water-absorbing conical tube extending from one end of the air filter element along its axial direction, and the water-spraying channel is provided on the peripheral wall at the drain end of the water-absorbing conical tube.

[0016] To further improve the implementation of this invention, the following structure is specifically adopted: the water-throwing channel is configured as a round hole, a strip hole, a square hole, or an elliptical hole.

[0017] To further improve the realization of the present invention, the following structure is specifically adopted: the inner wall of the water-absorbing conical tube is provided with a water-stirring blade or spiral groove extending along its axial direction.

[0018] To further improve the implementation of the present invention, the following structure is specifically adopted: the rotating water-throwing body further includes an end plate connected to the drainage end of the water-absorbing cone, and the width of the second annular space at the end plate is smaller than the width of the second annular space at the water-absorbing cone.

[0019] To further improve the implementation of this invention, the following structure is specifically adopted: the end plate is connected to a plurality of water-blocking blades arranged sequentially around the rotation axis on the outside of the water-absorbing cone. The water-blocking blades block the far end of a portion of the water-throwing channel to block the water thrown out from the portion of the water-throwing channel. A water passage gap is formed between adjacent water-blocking blades to allow the water thrown out from the water-throwing channel to move towards the peripheral wall of the filter element.

[0020] When the above-mentioned structure is adopted, the water-blocking blades can block part of the water curtain, further disperse and refine the water droplets through collision, and also accelerate the water droplets attached to them to be thrown out, creating a more complex water curtain in the second ring of air.

[0021] To further improve the implementation of the present invention, the following structure is specifically adopted: the end plate is provided with an exhaust port that allows air in the second annular space to be discharged outward.

[0022] When the above-mentioned structure is adopted, the exhaust holes provided on the end plate can increase the ventilation area between the second annulus and the outside, and can increase the ventilation volume of the second annulus.

[0023] To further improve the implementation of this invention, the following structure is specifically adopted: the air humidification and purification module further includes a water-blocking ring, which includes a water-impermeable water-blocking peripheral wall and a module air inlet disposed on the water-blocking peripheral wall; the driving device is connected to the water-blocking peripheral wall, and the air filter element is rotatably disposed within the water-blocking peripheral wall, forming a first annular space between the filter element peripheral wall and the water-blocking peripheral wall, and the module air inlet communicating the first annular space with the outside of the air humidification and purification module; wherein, the air filter element is configured as a gas-liquid exchange filter element, and when the air filter element rotates relative to the water-blocking peripheral wall, at least a portion of the water entering the air filter element can be thrown out towards the water-blocking peripheral wall under centrifugal force to form a water curtain.

[0024] When the above-described structure is adopted, the water-retaining ring and the air filter element are fitted inside and out, so that the water-retaining ring, the air filter element, and the rotating water-throwing body sequentially form a second annulus and a first annulus connected by the air filter element from the inside out. Since the air filter element is a continuously rotating gas-liquid exchange filter element, after the water curtain in the second annulus hits the filter element's peripheral wall, some of it will enter the filter element to form a water film or be broken into fine water droplets that come into contact with the air for filtration. Then, under the action of centrifugal force, the water will be thrown towards the water-retaining peripheral wall through the pores on the filter element's peripheral wall and into the first annulus to form a water curtain. In this way, the air undergoes three stages of filtration: water curtain – filter – water curtain, through the first ring, the filter element's periphery, and the second ring. This enhances the air purification effect. Specifically, the air undergoes a water curtain filtration in the first ring before passing through the air filter element, which improves the cleanliness of the air entering the filter element's periphery and reduces the filtration burden on the filter element's periphery. In addition, the continuous rotation of the filter element's periphery causes at least some impurities to be thrown out with the water under the action of centrifugal force, resulting in a self-cleaning effect. This effectively reduces or prevents clogging, maintains a better purification effect for a longer period, extends the life of the air filter, and eliminates the need for frequent replacements.

[0025] To further improve the present invention, the following structure is specifically adopted: the wheel frame is fixedly connected to the water-blocking ring body, and the wheel rim is rotatably connected to the water-blocking ring body.

[0026] To further improve the implementation of this invention, the following structure is specifically adopted: the core material is configured as a single-layer stainless steel wire mesh roll or a multi-layer stainless steel wire mesh roll. The single-layer roll includes a single layer of stainless steel wire mesh, and the multi-layer roll includes multiple layers of stainless steel wire mesh wrapped in sequence.

[0027] To further improve the implementation of the present invention, the following structure is specifically adopted: in a multi-layer stainless steel wire mesh roll, at least some of the mesh openings of the stainless steel wire mesh in adjacent layers are misaligned.

[0028] To further improve the implementation of this invention, the following structure is specifically adopted: it also includes a funnel-shaped water receiving tray with a downward narrowing opening disposed in the first annulus. The water receiving tray is fixedly connected to the water-blocking peripheral wall. The water receiving tray is disposed below the air filter element so as to collect the water thrown out from the air filter element and gather it downwards. The peripheral wall of the water receiving tray is provided with a water receiving tray air inlet. The module air inlet communicates with the first annulus through the water receiving tray air inlet.

[0029] When the above-mentioned structure is adopted, the funnel-shaped water receiving tray can reduce part of the impact force of the water droplets falling from above by using its inclined funnel wall, which can reduce some of the operating noise.

[0030] To further improve the implementation of this invention, the following structure is specifically adopted: the water receiving tray is detachably connected to the water-blocking peripheral wall.

[0031] To further improve the implementation of this invention, the following structure is specifically adopted: a water-dividing eave is provided on the peripheral wall of the water receiving tray at the top edge of the air inlet of the water receiving tray. The water-dividing eave can block the water coming from above and divert the water to the side of the air inlet of the water receiving tray to prevent water from entering the air inlet of the water receiving tray.

[0032] When the above-mentioned structure is adopted, the water divider can effectively prevent water on the water receiving tray from flowing into the air inlet of the water receiving tray, thus avoiding affecting the air intake.

[0033] The present invention also provides an air humidifier and purifier, including a housing, the aforementioned air humidifier and purifier module, and a fan; the housing is provided with a purifier air inlet and a purifier air outlet; the air humidifier and purifier module is disposed inside the housing and communicates with the purifier air inlet and the purifier air outlet to form a purification air duct, and the driving device of the air humidifier and purifier module is connected to the housing; the fan is connected to the housing and is capable of driving air outside the housing to enter from the purifier air inlet, flow through the air humidifier and purifier module for purification, and then exit from the purifier air outlet into the housing.

[0034] To further improve the implementation of this invention, the following structure is specifically adopted: a drive motor is provided inside the housing, and the output shaft of the drive motor is connected to the input shaft of the drive device of the air humidification and purification module to drive the air filter and the rotating water-spinning body of the air humidification and purification module to rotate.

[0035] To further improve the implementation of this invention, the following structure is specifically adopted: the air humidifier and purifier further includes a water storage tank with a top opening; the bottom end of the water-blocking peripheral wall of the air humidifier and purifier module is connected to the water storage tank located below it and supported by the water storage tank; the first annular space of the air humidifier and purifier module is connected to the water storage tank; the module air inlet of the air humidifier and purifier module is located at the wall plate of the water-blocking peripheral wall; and the water inlet of the rotating water-spinning body of the air humidifier and purifier module is located in the water storage tank.

[0036] To further improve the implementation of this invention, the following structure is specifically adopted: the water-retaining peripheral wall is detachably connected to the water storage tank.

[0037] To further improve the implementation of the present invention, the following structure is specifically adopted: the inner wall of the water-blocking peripheral wall is connected to a water-blocking sill protruding inward, and the water-blocking sill is located in the water storage tank so as to block the water flow moving circumferentially close to the inner wall of the water-blocking peripheral wall.

[0038] When the above-mentioned structure is adopted, the water-blocking sill in the water storage tank can block the water flow moving circumferentially along the inner side wall close to the water-blocking circumferential wall. This can prevent the water in the water storage tank from rotating under the rotational action of the self-priming rotating water-throwing body, so as to ensure the water intake of the rotating water-throwing body to ensure the water curtain density and the amount of water entering the filter element's peripheral wall, thereby ensuring the purification effect.

[0039] To further improve the implementation of this invention, the following structure is specifically adopted: the bottom opening of the water receiving tray of the air humidification and purification module is located in the water storage tank.

[0040] When the above-mentioned structure is used, the water receiving tray can prevent water droplets from falling directly into the water storage tank and causing noise.

[0041] To further improve the implementation of this invention, the following structure is specifically adopted: the water storage tank is detachably connected to the housing, the output shaft of the drive motor is detachably connected to the input shaft of the drive device, and the housing is provided with a doorway through which the air humidification and purification module can pass.

[0042] With the above-described structure, the air humidification and purification module can be removed from the housing for maintenance.

[0043] To further improve the implementation of this invention, the following structure is specifically adopted: the output shaft of the drive motor is horizontally positioned and connected to the input shaft of the drive device using a worm gear or bevel gear set; the water storage tank is movably connected to the housing; and the air humidification and purification module can move towards the doorway in a direction parallel to the output shaft of the drive motor so that the input shaft of the drive device is disengaged from the output shaft of the drive motor.

[0044] With the above-mentioned structure, the connection between the drive motor and the drive device does not require consideration of the layout and disassembly of the power cord. It can be disconnected and connected by moving the air humidification and purification module, which makes it easy to disassemble and assemble the air humidification and purification module. It is very suitable for ordinary people without professional skills to perform maintenance of the air humidification and purification module themselves.

[0045] To further improve the implementation of this invention, the following structure is specifically adopted: the housing is provided with a track, and the water storage tank is equipped with wheels and connected to the track through the wheels to achieve a mobile connection.

[0046] To further improve the implementation of this invention, the following structure is specifically adopted: a wheel limiter is provided on the housing at the track, and when the output shaft of the drive motor is connected to the input shaft of the drive device, the wheel and the wheel limiter are in a cooperating state to restrict the movement of the air humidification and purification module along the track.

[0047] To further improve the implementation of this invention, the following structure is specifically adopted: a door is connected to the doorway of the housing, and a second clamp is provided on the inner side of the door; a first clamp is provided on the inner side of the housing, and when the output shaft of the drive motor is connected to the input shaft of the drive device, the second clamp and the first clamp can be positioned in the housing in a closing posture.

[0048] To further improve the implementation of this invention, the following structure is specifically adopted: the housing is connected to a water injection pipe, the discharge end of the water injection pipe is connected to the water storage tank, and the water injection end of the water injection pipe is located outside the housing.

[0049] To further improve the implementation of this invention, the following structure is specifically adopted: a water injection funnel is inserted into the water injection end of the water injection pipe.

[0050] To further improve the implementation of this invention, the following structure is specifically adopted: the water injection funnel is configured as a foldable funnel.

[0051] When the above-mentioned structure is adopted, the foldable water inlet funnel installed on the water inlet pipe can be unfolded when water is being added, or folded back into the water inlet pipe when water is not being added, or laid flat on the shell to keep the appearance of the air humidifier and purifier clean.

[0052] The present invention also provides an air conditioner, including an indoor unit casing and the aforementioned air humidifier and purifier, wherein the air humidifier and purifier is disposed in the air conditioning duct of the indoor unit casing and is used to purify the air entering the air conditioning duct.

[0053] To further improve the implementation of this invention, the following configuration is adopted: the air humidifier and purifier is located at the return air vent of the indoor unit casing.

[0054] The present invention has the following advantages and beneficial effects:

[0055] In this invention, the rotating water-spraying body of the air humidification and purification module is inner and outer sleeved with the air filter and can be rotated in opposite directions by a drive device. This causes the air to generate a more turbulent airflow after passing through the air filter and entering the second ring air. This can prolong the path of the airflow in the second ring air to a certain extent and increase the time it spends in the second ring air. This allows the air to have a longer contact time and a larger area with the water curtain in the second ring air, thereby improving the air purification effect. Attached Figure Description

[0081] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0082] In the description of this invention, it should be noted that, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0083] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0084] To address the issues of poor purification performance and frequent filter replacement required in existing water-washable air purifiers, this paper first proposes an air humidification and purification module, then proposes an air humidification and purification purifier based on this module, and finally proposes an air conditioner based on this air humidification and purification purifier.

[0085] Example 1:

[0086] An air humidification and purification module has a good air purification effect, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, it is specifically configured with the following structure:

[0087] In this embodiment, the air humidification and purification module is as follows: Figure 1 As shown, it includes an air filter element 1, a rotating water-spraying body 2, and a drive device 3. Both the air filter element 1 and the rotating water-spraying body 2 are rotating bodies. The air filter element 1 is sleeved outside the rotating water-spraying body 2. The drive device 3 is connected to the air filter element 1 and the rotating water-spraying body 2 to drive them to rotate in the opposite direction.

[0088] The air humidification and purification module has a virtual rotation axis a. The axis of the air filter 1 is coaxial with the rotation axis a and can rotate around the rotation axis a. The rotating water-spraying body 2 is rotatably set in the inner cavity of the air filter 1. The water inlet end of the rotating water-spraying body 2 extends downward from the bottom of the air filter 1 to prepare for connection with a water pump or water tank. A second annular cavity c is formed between the peripheral wall of the rotating water-spraying body 2 and the cavity wall of the air filter 1. The second annular cavity c is used to receive the air filtered by the air filter 1 and to ensure that a water curtain can be generated in it to filter the air when the rotating water-spraying body 2 rotates.

[0089] The drive unit 3 can drive the air filter element 1 to rotate around the rotation axis a through the output power, and can simultaneously drive the rotating water jet 2 to rotate in the opposite direction relative to the rotation direction of the air filter element 1 around its own rotation axis. The rotation axis of the rotating water jet 2 can be located at an appropriate eccentric position in the second annular cavity c, as long as it can generate a water curtain in the second annular cavity c. In order to make the water curtain uniform and ensure that the purification effect is consistent throughout the second annular cavity c, it is preferable to set the rotation axis of the rotating water jet 2 coaxially with the rotation axis a, so that the rotating water jet 2 is located at the center of the cavity of the air filter element 1. In this way, the distance between the peripheral wall of the rotating water jet 2 and the inner wall of the cavity of the air filter element 1 will be consistent.

[0090] The rotating water jet 2 is installed inside and outside the air filter 1 and can rotate in opposite directions via the drive device 3. This causes the air to enter the second ring after passing through the air filter 1, creating a more turbulent airflow. This prolongs the airflow path and time in the second ring, allowing for longer and larger-area contact between the air and the water curtain, thus improving air purification. Because the air undergoes water curtain purification, it carries some moisture and is discharged after purification, effectively humidifying the indoor air.

[0091] One specific configuration of the components in the air humidification and purification module is as follows:

[0092] like Figure 2As shown, the air filter element 1 includes a filter element peripheral wall formed around the rotation axis a, capable of passing through and filtering air. The filter element peripheral wall consists of a cylindrical frame 11 and a core material 12 detachably installed in the frame 11. A rotating water-spraying body 2 is rotatably disposed inside the filter element peripheral wall, forming a second annular space c between the peripheral wall of the rotating water-spraying body 2 and the peripheral wall of the filter element, allowing air to pass through. The peripheral wall of the frame 11 has multiple windows for air passage, and a ring of receiving plates is provided at the bottom to support the core material 12. A through hole is provided at the center of the receiving plate to allow the rotating water-spraying body 2 to pass through. The core material 12 is designed as a gas-liquid exchange filter element that easily allows water to pass through. It can be a single-layer or multi-layer metal or non-metal wire mesh roll, or a single-layer or multi-layer metal or non-metal porous screen barrel. It is preferably a multi-layer stainless steel wire mesh roll, which can prevent odor generation over a long period of time and save costs. A multi-layer stainless steel wire mesh roll comprises multiple layers of stainless steel wire mesh wound sequentially, with at least some of the mesh openings in adjacent layers staggered to create a complex and varied pore path. The stainless steel wire mesh can be commercially available products, but is preferably the air filter mesh used in tractor air filters, such as the mesh used in Dongfanghong or Lovol 454, to ensure a relatively complex pore structure after the multiple layers of stainless steel wire mesh are wound together.

[0093] like Figure 2 and Figure 3 As shown, the rotating water-spraying body 2 borrows from the existing structure used in water-washing air humidifiers for spraying water curtains. It can be a pump-suction type rotating water-spraying body with a water pump at the inlet end, or it can be a self-priming type rotating water-spraying body. This embodiment preferably uses a self-priming type rotating water-spraying body and will continue to explain using this as an example. The self-priming type rotating water-spraying body is used to save on the installation of a water pump and reduce wiring, thereby saving costs and reducing operating noise. The self-priming type rotating water-spraying body 2 includes a water-suction conical pipe 21 with the rotation axis a as the axis. The water inlet end of the water-suction conical pipe 21 extends downward along its axial direction from the through hole at the center of the receiving plate of the frame 11. The peripheral wall of the water-suction conical pipe 21 at the top drain end is provided with multiple water-spraying channels arranged sequentially along the peripheral wall.

[0094] In addition to the round hole shown in the figure, the water-throwing channel can also be set as a strip hole, square hole, or elliptical hole, etc.

[0095] At least part of the water-throwing channel on the rotating water-throwing body 2 should be located inside the peripheral wall of the filter element, preferably as follows: Figure 2 As shown, the water is concentrated on a section of the peripheral wall at the top. When the rotating water-throwing body 2 rotates, all the water in the water-throwing channel can enter the second annular cavity c under the action of centrifugal force and move towards the peripheral wall of the filter element to form a water curtain, thus obtaining a large water curtain density.

[0096] The density of the water curtain generated in the second annular cavity c is also determined by the water absorption capacity of the water suction conical tube 21. In order to have a large self-absorption capacity, multiple water stirring blades 22 can be arranged equidistantly along the circumference of the inner wall of the water suction conical tube 21. The water stirring blades 22 themselves extend along the axial direction of the water suction conical tube 21 from the water inlet end of the water suction conical tube 21 toward the top end; or spiral grooves extending along the axial direction can be provided on the inner wall of the water suction conical tube 21.

[0097] like Figure 2 and Figure 4 As shown, the drive unit 3 adopts an independent dual-output structure. It can be a direct-drive configuration, meaning it includes at least two separate connecting shafts for connecting to two motors, enabling independent drive of the two output ends. Alternatively, it can employ a coaxial dual-output transmission structure, commonly seen in the coaxial twin-rotor transmission structure used in helicopters or ships. This structure utilizes the two output ends of the coaxial dual-output transmission structure, connecting them respectively to the air filter 1 and the rotating water jet 2 to achieve their opposite rotational motion. It can also adopt a configuration such as... Figure 4 The planetary gear transmission structure shown in this embodiment is preferably used as the drive device 3. Reasons for this include its simple structure and flat shape, which can reduce costs or the height of the air filter module. Specifically, the planetary gear transmission structure is positioned above the air filter element 1 and the rotating water-spraying body 2. The wheel frame 34 of the planetary gear transmission structure is locked. The planetary gears 32 are mounted on the wheel frame 34, with the sun gear 31 and wheel rim 33 serving as outputs and the sun gear 31 as the input. The wheel rim 33 is mounted on the wheel frame 34 via a slewing bearing, allowing it to rotate relative to the wheel frame 34. The input shaft of the sun gear 31 is mounted on the wheel frame 34 via a bearing, allowing it to rotate relative to the wheel frame 34. The output shaft of the sun gear 31 of the planetary gear transmission structure is coaxially and fixedly connected to the water intake cone 21 of the rotating water-spraying body 2. The wheel rim 33 of the planetary gear transmission structure is coaxially and fixedly connected to the air filter element 1 and the frame 11.

[0098] This planetary gear train can be either a gear train or a friction gear train.

[0099] like Figures 2-4As shown, in order to ensure that the air entering the second annular cavity c can be discharged from the air humidification and purification module through a defined path, a closed air passage is designed from the second annular cavity c to the wheel frame 34. Specifically, the wheel frame 34 is configured as a flange structure with multiple exhaust channels 341 arranged around the rotation axis a. An exhaust pipe 35 is fixedly connected to the wheel rim 33 and is coaxially arranged with it. The exhaust pipe 35 is also coaxially arranged with the air filter element 1. The locking block on the outer wall of the bottom of the exhaust pipe 35 engages with the locking groove on the peripheral wall of the top of the frame 11 of the air filter element 1, allowing the air filter element 1 to be removed from the exhaust pipe 35 for cleaning and replacement. The upper and lower ends of the exhaust pipe 35 connect the upper exhaust channel 341 to the lower second annular cavity c, so that the air in the second annular cavity can rise through the exhaust pipe 35, pass through the exhaust channel 341, and be discharged from the air humidification and purification module.

[0100] like Figure 3 As shown, in order to extend the path from the second annular cavity c to the exhaust pipe 35, the rotating water-slinging body 2 is designed as a flange-type part. Specifically, a circular end plate 23 is connected to the drain end of the water-absorbing cone 21 of the rotating water-slinging body 2. The diameter of the end plate 23 is larger than the outer diameter of the water-absorbing cone 21, so that the width of the second annular cavity at the end plate 23 is smaller than the width of the second annular cavity at the water-absorbing cone 21. In this way, the airflow near the water-absorbing cone 21 will flow towards the edge of the end plate 23 and pass through the gap between the end plate 23 and the filter element peripheral wall, which can increase the airflow path and residence time. Considering that the setting of the end plate 23 will affect the ventilation area between the exhaust pipe 35 and the second annular cavity c, and affect the ventilation volume of the second annular cavity c, multiple exhaust holes 231 connecting the second annular cavity c and the exhaust pipe 35 can be opened on the end plate 23.

[0101] like Figure 3 As shown, in order to further refine the water droplets forming the water curtain and increase its complexity, multiple water-blocking blades 24 are fixedly connected to the bottom surface of the end plate 23. These blades are arranged equidistantly around the rotation axis on the outside of the suction conical tube 21, with a gap between them. The extension path of the blades 24 can be arc-shaped or straight. The blades 24 block the water at the far end of a portion of the water-throwing channel, thus further breaking down and refining the water droplets through collision. A water-passing gap is formed between adjacent blades 24, allowing water thrown from the water-throwing channel to move towards the filter element's peripheral wall. This allows some water droplets that are in contact with the blades 24 to pass through, while also accelerating the ejection of water droplets attached to the blades 24, creating a more complex water curtain in the second annular space along with the existing one.

[0102] Example 2:

[0103] This embodiment is a further optimization based on the above embodiments. To better realize the present invention, the following configuration structure is specifically adopted:

[0104] In this embodiment, the air humidification and purification module further increases the area for air filtration from two to three. The filtration type of the added filtration area is water curtain filtration. Here, the air filter element 1 needs to be a gas-liquid exchange filter element.

[0105] Specifically, such as Figure 6 and Figure 7 As shown, the air humidification and purification module also includes a water-blocking ring 4, which is a rotating body about the rotation axis a. It includes a water-impermeable water-blocking peripheral wall 41 and multiple module air inlets 42 arranged sequentially around the lower part of the water-blocking peripheral wall 41. The top of the water-blocking peripheral wall 41 is fixedly connected to the wheel frame 34 of the drive device 3, and the wheel rim 33 is rotatably connected to the top of the water-blocking peripheral wall 41 via a slewing bearing. One function of the water-blocking ring 4 is to serve as a support for the air humidification and purification module; another function is to form another filtration area between it and the air filter element 1.

[0106] The air filter element 1 is coaxially and rotatably mounted within the water-retaining peripheral wall 41. Thus, the rotating water-spinning body 2, the air filter element 1, and the water-retaining ring 4 form a structure that is nested sequentially from the outside in. The gap between the filter element peripheral wall and the water-retaining peripheral wall 41 forms a first annular space b. The module air inlet 42 serves as the air inlet for the entire air humidification and purification module, connecting the first annular space to the outside of the air humidification and purification module.

[0107] Reference Figure 7 When the drive device 3 provides output, the rotating water-throwing body 2 rotates relative to the air filter element 1. The water in the water-throwing channel is thrown out towards the peripheral wall of the filter element under the action of centrifugal force, forming a water curtain in the second annular cavity c. Some of the thrown-out water droplets enter the air filter element 1 and form a water film in the pores of the core material 12. The air filter element 1, which rotates in the opposite direction to the rotating water-throwing body 2, throws the water in the core material 12 towards the water-blocking peripheral wall 41 using the generated centrifugal force, forming a water curtain in the first annular cavity b.

[0108] In this embodiment, the water-blocking ring 4 is inner and outer sleeved with the air filter element 1, so that the water-blocking ring 4, the air filter element 1, and the rotating water-slinging body 2 sequentially form a second annular space c and a first annular space b connected by the air filter element 1 from the inside out. Since the air filter element 1 is a continuously rotating gas-liquid exchange filter element, after the water curtain in the second annular space c hits the filter element peripheral wall of the air filter element 1, some of it will enter the filter element to form a water film or be broken into fine water droplets and then come into contact with the air for filtration. Afterwards, under the action of centrifugal force, the water will be thrown towards the water-blocking peripheral wall 41 through the pores on the filter element peripheral wall to form a water curtain in the first annular space. In this way, the air undergoes three stages of filtration—water curtain-filter element-water curtain—in the first annular space b, the core material 12, and the second annular space c. Compared with the two-stage filtration in the prior art, this improves the air purification effect. Before passing through the air filter element 1, the air undergoes a water curtain filtration in the first ring air b, which improves the cleanliness of the air entering the core material 12 and reduces the filtration burden on the core material 12. In addition, the continuous rotation of the filter element's peripheral wall causes at least some impurities to be thrown out with the water under the action of centrifugal force, which has a self-cleaning effect. This can effectively reduce or prevent clogging, maintain a better purification effect for a long time, extend the service life of the air filter element 1, and eliminate the need for frequent replacements.

[0109] Example 3:

[0110] This embodiment is a further optimization based on the above embodiments. To better realize the present invention, the following configuration structure is specifically adopted:

[0111] In this embodiment, the air humidification and purification module is further optimized for noise reduction.

[0112] Since air humidification and purification modules are usually equipped with a water tank at the bottom for collecting water, if the water droplets are allowed to fall into the water tank, there will be dripping noise.

[0113] like Figures 6-8 As shown, the air humidification and purification module is equipped with a water collection tray 6. The water collection tray 6 is a funnel-shaped component with a downward-sloping opening, coaxially disposed in the first annular cavity b. The top edge of the water collection tray 6 is fixedly connected to the water-blocking peripheral wall 41. The connection between the top edge of the water collection tray 6 and the water-blocking peripheral wall 41 should preferably have a certain degree of sealing to prevent air or water from leaking through. From the perspective of its placement, the water collection tray 6 is located below the air filter 1, and the air filter 1 is located inside the water collection tray 6. This allows for better collection of water splashed out from the air filter 1 and its downward convergence. The funnel-shaped water collection tray 6 can reduce some of the impact force of the water droplets dripping from above by utilizing its inclined funnel wall, which can reduce some of the operating noise. It can also smoothly converge the collected water downward into the water tank or water pipe, reducing dripping noise.

[0114] A sound-absorbing pad can be laid on the surface of the water receiving tray 6 to further reduce the noise generated when water droplets fall on the water receiving tray 6 or water flows on the water receiving tray 6.

[0115] like Figure 8 As shown, the peripheral wall of the water receiving tray 6 is provided with a strip-shaped air inlet 61 extending upward along the generatrix from the bottom edge. Multiple air inlets 61 are provided around the rotation axis a. The module air inlet 42 is connected to the first annulus b through the water receiving tray air inlet 61, that is, at least part of the air entering from the module air inlet 42 will pass through the water receiving tray air inlet 61 and enter the first annulus b.

[0116] like Figure 8 As shown, if water directly enters the air inlet 61 of the water receiving tray, it will not only obstruct the air passing through it, but also drip directly downwards, creating a lot of noise. To avoid these problems, a water-dividing eave 62 is provided on the peripheral wall of the water receiving tray 6 at the top edge of the air inlet 61. The water-dividing eave 62 is "human" shaped, with its two ends extending beyond the two sides of the air inlet 61. In this way, the water-dividing eave 62 can block the water coming from above and divert the water to the two sides of the air inlet 61 to prevent water from entering the air inlet 61. This can effectively prevent water on the water receiving tray 6 from flowing into the air inlet 61, thus avoiding affecting the air intake and generating a lot of noise.

[0117] The top edge of the water receiving tray 6 is engaged with the locking block on the inner wall of the water-blocking peripheral wall 41 via a locking groove, so that the water receiving tray 6 can be removed from the water-blocking peripheral wall 41 for cleaning.

[0118] Example 4:

[0119] This embodiment further provides an air humidifier and purifier based on any of the above embodiments, specifically employing the following configuration structure:

[0120] In this embodiment, the air humidifier and purifier includes a housing 7, a fan 8, and the air humidifier and purifier module in any of the above embodiments.

[0121] This embodiment preferably uses the air humidification and purification module from Embodiment 3, specifically as follows: Figures 5-7 As shown.

[0122] In this embodiment, a self-priming rotating water jet 2 is used as an example for illustration.

[0123] like Figure 5 and Figure 7As shown, the housing 7 is a cylindrical hollow shell with a peripheral wall, a bottom plate, and a top plate. An air inlet 71 is located at the lower part of the peripheral wall, and an air outlet 72 is located on the top plate. The air humidification and purification module is entirely housed within the housing 7. The module's air inlet 42 communicates with the air inlet 71, and the exhaust channel 341 communicates with the air outlet 72, forming a purification air duct that sequentially connects the first annulus b, the air filter 1, and the second annulus c. The wheel frame 34 in the drive device 3 of the air humidification and purification module is fixedly connected to the housing 7. The fan 8 is fixedly connected to the housing 7 and located above the air humidification and purification module. It drives air from outside the housing 7 to enter through the air inlet 71, flow through the air humidification and purification module for purification, and then exit from the air outlet 72 into the housing 7.

[0124] like Figure 6 and Figure 7 As shown, the air humidifier and purifier provides a drive motor 9 for the drive unit 3, which is fixed in the housing 7 by a mounting bracket. The output shaft of the drive motor 9 is connected to the input shaft of the drive unit of the air humidifier and purifier module to drive the air filter 1 and the rotating water-spraying body 2 of the air humidifier and purifier module to rotate. The drive motor 9 is preferably an electric motor.

[0125] like Figure 6 and Figure 7 As shown, the air humidifier purifier is equipped with a water storage tank 5 for the air humidification and purification module. The water storage tank 5 has a circular box with an open top to receive water collected downwards from the water tray 6. The bottom of the water tray 6 extends into the water storage tank 5 and is positioned close to the bottom plate of the water storage tank 5, which can minimize the noise caused by water dripping directly into the water storage tank 5. The water-blocking peripheral wall 41 of the water-blocking ring 4 of the air humidifier purifier module extends into the water storage tank 5 and is detachably placed on the bottom plate of the water storage tank 5, supported by the water storage tank 5. The first annular space b of the air humidifier purifier module communicates downwards with the water storage tank 5 through the air inlet 61 of the water tray and the bottom of the water tray 6. At the same time, it communicates with the internal space of the housing 7 through the module air inlet 42 set on the wall plate of the water-blocking peripheral wall 41, and then with the outside through the purifier air inlet 71 of the housing 7. The water inlet end of the water inlet pipe 21 of the rotating water-spinning body 2 of the air humidification and purification module extends downward into the water storage tank 5 and is at a distance from the bottom plate of the water storage tank 5.

[0126] like Figure 7 and Figure 9As shown, since the rotating water-spraying body 2 in this embodiment is self-priming, when the rotating water-spraying body 2 rotates, the suction conical tube 21 can not only suck up and lift the water in the water storage tank 5, but also make the water in the water storage tank 5 rotate. This will affect the water absorption capacity of the suction conical tube 21, resulting in a decrease in the water curtain density. To address this, the inner wall of the water-blocking peripheral wall 41 is connected to multiple water-blocking sills 43 arranged sequentially along the circumference. The water-blocking sills 43 extend radially inward and protrude. Since the water-blocking sills 43 are located in the water storage tank 5, they can block the water flow moving circumferentially close to the inner wall of the water-blocking peripheral wall 41. This can prevent the water in the water storage tank 5 from rotating under the rotation of the self-priming rotating water-spraying body 2, so as to ensure the water intake of the rotating water-spraying body 2 to ensure the water curtain density and the amount of water entering the filter element peripheral wall of the air filter element 1, thereby ensuring the purification effect.

[0127] Example 5:

[0128] This embodiment is a further optimization based on the above embodiments. To better realize the present invention, the following configuration structure is specifically adopted:

[0129] In this embodiment, the air humidification and purification module of the air humidifier and purifier can be removed from the housing 7 for maintenance.

[0130] Specifically, such as Figure 5 As shown, a door opening is provided on the peripheral wall of the housing 7, and the size of the door opening is sufficient to remove the air humidification and purification module from the housing 7. A door 73 is installed on the peripheral wall of the housing, which closes the door opening. When the air humidification and purification module needs to be installed or removed, the door 73 can be removed or opened to expose the door opening.

[0131] To allow the air humidification and purification module to be easily removed from the housing 7, the connection between the output shaft of the drive motor 9 and the input shaft of the drive device needs to be detachable.

[0132] Specifically, such as Figure 6 and Figure 7 As shown, the output shaft of the drive motor 9 is horizontally positioned, and an output bevel gear is connected to its shaft end. The input shaft of the sun gear 31 of the drive device 3 is vertically positioned, and another bevel gear is connected to its shaft end. The output shaft of the drive motor 9 and the input of the sun gear 31 are connected at a 90° angle through the bevel gear.

[0133] The water tank 5 is preferably connected to the bottom plate of the housing 7 in a translational manner, so that the entire air humidification and purification module can move towards the doorway along a direction parallel to the output shaft of the drive motor 9 as the water tank 5 moves. The drive motor 9 is located on the opposite side of the doorway so that when the air humidification and purification module moves towards the doorway, the input shaft of the drive device 3 can be disengaged from the output shaft of the drive motor 9.

[0134] Of course, the output shaft of the drive motor 9 and the input shaft of the drive device 3 can also be connected by a worm gear structure or the like.

[0135] The translation of the water tank 5 and the housing 7 is achieved by the installation of two tracks 74. The tracks 74 are laid side by side on the bottom plate of the housing 7 and extend in a straight line parallel to the output shaft of the drive motor 9 towards the door opening. In order to cooperate with the tracks 74, two pairs of wheels 51 are installed at the bottom of the water tank 5, and the water tank 5 is connected to the tracks 74 through the wheels 51.

[0136] The drive motor 9 and the drive device 3 are detachably connected using the above structure. This eliminates the need to consider the layout of the power cord and the hassle of disassembly and assembly. The air humidification and purification module can be detached and connected by sliding it horizontally. This makes it easy to disassemble and assemble the air humidification and purification module, making it very suitable for ordinary people without professional skills to perform maintenance on the air humidification and purification module themselves.

[0137] To facilitate the installation of the air humidification and purification module, a wheel limiter 75 is provided on the bottom plate of the housing 7 at the track 74. This wheel limiter 75 can be a groove or a protrusion. When the output shaft of the drive motor 9 is connected to the input shaft of the sun gear 31 via a bevel gear, the wheel 51 and the wheel limiter 75 are in a perfectly matched state. At this time, the wheel limiter 75 can restrict the movement of the air humidification and purification module along the track 74, allowing the installation position of the air humidification and purification module to be determined in one step, reducing adjustment time.

[0138] To improve the stability of the air humidification and purification module during operation after installation, the housing 7 uses a clamping structure to secure the module. Specifically, for example... Figure 10 and Figure 11 As shown, an arc-shaped second clamp 731 is provided on the inner side of the door 73, and an arc-shaped first clamp 76 is provided on the inner side of the periphery wall of the housing 7. When the door 73 is closed with the periphery wall, the first clamp 76 and the second clamp 731 can combine to form a complete circular clamp. When the output shaft of the drive motor 9 is connected to the input shaft of the sun gear 31, the second clamp 731 and the first clamp 76 clamp the water-blocking periphery wall 41 in a closed clamping posture, positioning the air filter module in the housing 7.

[0139] Example 6:

[0140] This embodiment is a further optimization based on the above embodiments. To better realize the present invention, the following configuration structure is specifically adopted:

[0141] In this embodiment, the air humidifier and purifier are further optimized in terms of ease of water filling.

[0142] like Figure 5 , Figure 7and Figure 12 As shown, a water injection pipe 10 is inserted into the top plate of the housing 7. The discharge end of the water injection pipe 10 extends into the module air inlet 42 and overlaps the top edge of the water storage tank 5, while pointing towards the water storage tank 5. The water injection end of the water injection pipe 10 is located outside the housing 7, and its end is flush with the top surface of the top plate.

[0143] To facilitate water addition and prevent spillage, a water inlet funnel 101 is inserted into the water inlet end of the water inlet pipe 10. In this embodiment, the water inlet funnel 101 is preferably a folding funnel. The folding funnel includes a connecting pipe and a folding body connected to the top of the connecting pipe. The folding body includes multiple skeletons arranged sequentially along the circumference of the connecting pipe and a funnel wall. The funnel wall covers the inner side of the skeletons. All skeletons can contract towards the center of the connecting pipe to form a funnel shape or fold completely. All skeletons can also unfold towards the outside of the connecting pipe to open the funnel wall to form a funnel shape or form a shape like... Figure 4 The funnel is flat as shown. The connecting pipe is inserted into the water injection pipe 10 and can move towards the drain end of the water injection pipe 10, causing the funnel wall to contract towards the center. A filter screen is installed on the connecting pipe to filter out impurities in the water.

[0144] For the specific structure of the folding funnel, please refer to the foldable funnel disclosed in the invention patent application with application number 201110337107.1.

[0145] The foldable water inlet funnel 101 installed on the water inlet pipe 10 can be unfolded when water is being added, or folded back into the water inlet pipe 10 when not adding water, or laid flat on the housing to keep the air humidifier and purifier looking neat.

[0146] Example 7:

[0147] This embodiment further provides an air conditioner based on the above embodiments, specifically employing the following configuration structure:

[0148] In this embodiment, the air conditioner includes an indoor unit casing and an air humidifier and purifier as described in any of the above embodiments. The air humidifier and purifier are disposed within the air conditioning duct of the indoor unit casing, and the air humidifier and purifier are preferably located near the return air vent of the indoor unit casing. When the air humidifier and purifier are used as a component of the air conditioner, the fan 8 can be omitted, and the air conditioner's built-in fan can be used.

[0149] The air purifier's air inlet 71 is connected to the return air inlet of the indoor unit casing, and the air outlet 72 is connected to the air blower inlet of the indoor unit casing, forming a complete air duct inside the air conditioner, which can purify the air entering the air duct of the indoor unit casing before blowing it out.

[0150] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
