Detailed Description

Fig. 1 is a schematic perspective view of an air purification apparatus, and as shown in fig. 1, the air purification apparatus of the present invention may include an air inlet portion 3, a water washing portion 1, and an air outlet portion 4 according to the flow direction of air. Washing portion 1 includes water tank 11 and the washing subassembly that sets up in water tank 11, this washing subassembly forms the water curtain with the water in the water tank 11 under the power that power portion 2 provided, dirty gas gets into washing portion 1 back by air inlet portion 3, can pass the water curtain that the washing subassembly formed, make dust in the dirty gas, the hydrone that bacterial virus etc. dissolved in water or by the water curtain, the anion is got rid of, thereby accomplish dirty gas's washing purification, clean gas after washing portion 1 washing purification is from air-out portion 4, with the air quality on every side of improving.

In fig. 1, the air cleaning device is further provided with a base body 5 for carrying a water tank 11, and the air inlet portion 3 and the power portion 2 can be arranged by relying on the base body 5 so as to realize modularized and integrated arrangement. In other words, the air inlet portion 3 may be formed integrally with the base 5 by molding, for example, a side wall or a bottom wall of the one piece member is used as the air inlet portion 3, and the bottom wall of the one piece member is used for mounting the power portion 2 and for supporting the water tank 11.

The water tank 11 has an air inlet communicating with the air inlet portion 3 and an air outlet communicating with the air outlet portion 4. Illustratively, the air outlet portion 4 may include an air outlet housing 41, the air outlet housing 41 may cover an air outlet of the water tank 11, and the purified air enters the air outlet housing 41 from the air outlet of the water tank 11, so that the purified air can be guided to any desired direction through the air outlet housing 41. For example, fig. 1 shows that the purified air discharged from the outlet of the water tank 11 is guided to the left, right, and rear sides in fig. 1 through the outlet cover 41.

The respective parts of the air cleaning apparatus are described in detail below.

The water tank 11 will be described first.

FIG. 2 is a perspective view of a water washing section; as shown in fig. 2, the water tank 11 may be made of a transparent material, for example, a transparent plastic material, and may be formed by molding. The tank 11 may contain a cleaning liquid for cleaning the air, which may be but is not limited to fresh water, for example, water mixed with a disinfectant. For the sake of simplicity of description, the following description is given by way of example of water, but this should not be taken as a specific limitation of the scope of protection.

As shown in fig. 2, the upper portion of the water tank 11 is for air flow, and the lower portion of the water tank 11 is for holding water. The intake vent 111 of the water tank 11 may be provided at an upper side wall of the water tank 11, and a primary filter assembly may be provided outside the intake vent 111 as described below.

As shown in fig. 2, the top of the water tank 11 may be opened to serve as an air outlet, and the air entering the water tank 11 may flow out from the top opening of the water tank 11. An upper water retaining structure 15 may be provided at the air outlet as described below.

It should be noted that the positions of the air inlet 111 and the air outlet may be different from those shown in fig. 2. For example, the positions of the intake vent 111 and the exhaust vent may be reversed, or in some examples, both the intake vent 111 and the exhaust vent may be disposed on opposite sidewalls of the water tank 11. The air purification device of the present scheme is described below by taking the air inlet 111 disposed on the sidewall of the water tank as an example, and for other setting modes of the air outlet, those skilled in the art can refer to the following description, which is not described herein again.

With continued reference to fig. 2, the number of the air inlets 111 may be multiple, but only one air inlet may be provided, and the shape and size of each air inlet 111 may be set according to actual needs. As shown in fig. 2, when the air inlet 111 is plural, the air inlets 111 may be uniformly distributed along the circumferential direction of the side wall of the water tank 11 so as to equally divide the air, so that the air entering the water tank 11 is uniformly distributed.

It should be noted that, when the air inlet is disposed on the side wall of the water tank 11 and the air outlet is located at the top of the water tank 11, the upper end surface of the air inlet should be lower than the plane of the water curtain formed by the water washing assembly, so that the dust-containing air entering the water tank 11 from the air inlet can flow out of the air outlet of the water tank 11 only after being cleaned by the water curtain. It should be noted that, since the water is influenced by gravity, the plane of the water curtain is generally indicated, and in principle, the upper end surface of the air inlet should be located below the intersection line of the water curtain and the side wall.

As can be seen from the above, the lower portion of the water tank 11 is used for containing water, so the side wall of the lower portion of the water tank can be provided with scale marks, so that a user can observe and control the liquid level condition of the water tank 11. It is easily understood that the water tank 11 may be made of a transparent material only at a portion where the graduation marks are provided, and the remaining portion is made of a non-transparent material, so that a user can observe the water level in the water tank 11 through the graduation marks of the transparent portion. Referring to FIG. 2, the tick mark may include the lowest liquid level line, which may be shown as "0"; the highest liquid level line may also be included, which may be indicated by "max". It will be appreciated that the scale line marked "max" is located below the air inlet.

In order to understand the utility model of the present solution more quickly, the water washing assembly will be described first. The structure of the water washing assembly includes but is not limited to the following possible implementation modes:

in one possible implementation, fig. 4 shows a schematic view of a water washing assembly for forming a water curtain, which can lift water stored in the water tank 11 and spray the water toward the inner wall of the water tank 11, as shown in fig. 4. Specifically, the water washing assembly may include a hollow cylinder 12, and a lower end of the cylinder 12 communicates with a lower end of the water tank 11. Illustratively, the lower end of the barrel 12 is open. A gap is provided between the lower end opening of the cylinder 12 and the bottom wall of the water tank 11 so that water in the water tank 11 enters the interior of the cylinder 12 from the gap. The power part 2 can rotate the cylinder 12 around its own axis so that the water entering the cylinder 12 gradually moves upward along the inner wall of the cylinder 12 by the rotating force. A plurality of water throwing holes 121 are circumferentially arranged on the side wall of the cylinder 12 close to the top end, and the water throwing holes 121 are higher than the highest liquid level of the washing liquid contained in the water tank 11, so that the water thrown up from the inner wall of the cylinder 12 is thrown out from the water throwing holes 121, is far away from the cylinder 12 at a certain initial speed (the initial speed is the linear speed of the positions of the water throwing holes 121), and gradually approaches the inner wall of the water tank 11 to form a water curtain so as to clean the gas entering from the air inlet. It is noted that the plurality of water-throwing holes 121 may be uniformly or non-uniformly arranged in a circle along the circumferential direction of the cylinder 12, and in some examples, a plurality of circles of water-throwing holes 121 may be further provided along the axis of the cylinder 12 to enhance the water washing purification effect.

In another implementation, the wash assembly includes a water tube that may include a first end and a second end, the first end of the water tube being extendable into the water stored in the tank to draw in water at the lower end of the tank; the second end of the water pipe may extend to the upper end of the water tank. The water pipe may be provided with a water pump for causing water in the water tank to flow from the first end to the second end. The water wash assembly further comprises a rotatable disc member, and water flowing down the second end of the water tube falls onto the rotatable disc member and is thrown out under the action of centrifugal force to form a water curtain.

In yet another possible implementation, instead of the rotatable disc-shaped part, a hollow arranged rotating body may be used, the upper end of which may be open and provided with through holes in its side walls. The water flowing out from the second end of the water pipe can enter the inside of the rotating body from the upper end opening of the rotating body and is thrown out from the through hole along the tangential direction of the rotating body, so that a water curtain is formed.

In some possible implementation manners, a water curtain, water mist and the like may be formed in the water tank by rotating the water curtain, the water pipe provided with a plurality of water outlets along the length direction, and two opposite nozzle structures, atomizers and the like, so that the air entering the water tank may be washed and purified.

In summary, there are various water washing assemblies for forming the water curtain from the water in the water tank 11, and the solution of the present application will be described below by taking the case that the water washing assembly includes the barrel 12 and the power part 2 drives the barrel 12 to rotate. Other water washing assembly structures can be found with reference to the present application and will not be described herein.

With continued reference to fig. 4, the side wall of the barrel 12 may be tapered from top to bottom toward the axis away from the barrel 12, i.e., the barrel 12 is configured in a generally conical shape with the small diameter end of the cone located below and the large diameter end of the cone located above to facilitate the water climbing up the inner wall of the barrel 12.

With continued reference to fig. 4, the barrel 12 may be divided into an upper section 122 and a lower section 123 connected to a lower end of the upper section 122, and the water slinging hole 121 may be provided in the upper section 122. The upper and lower sections may be integrally formed as a single piece, such as by injection molding, to facilitate structural stability of the cartridge body 12. Of course, the upper section and the lower section of the cylinder 12 may also be separate pieces, and the two sections are assembled together by screwing, screwing or welding, and the lower end of the upper section 122 and the upper end of the lower section 123 may be sleeved together, for example, the upper end of the lower section 123 may extend into the lower end of the upper section 122, so as to enhance the sealing property between the upper section 122 and the lower section 123.

It should be noted that, when the aperture of the lower end of the upper section 122 is larger than the aperture of the upper end of the lower section 123, the connection between the upper section 122 and the lower section 123 can be achieved by a step. By forming the step part between the upper section and the lower section, a temporary storage area can be provided for water climbing on the inner wall of the cylinder 12, which is beneficial to improving the water quantity thrown out from the water throwing hole 121.

Alternatively, fig. 5 shows a cross-sectional view of a cylinder and a power section in order to embody the connection between the upper section 122 and the lower section 123, the upper section 122 may include an upper cylinder and an inner flange, the inner flange may include a radial section and an axial section, the radial section may abut against an upper end face of the outer flange mentioned below, and the axial section may be bent downward with respect to the radial section.

The lower section 123 may be embedded within the flange. For example, the lower segment 123 may include a lower cylinder and an outer flange, the outer flange may be sleeved outside the upper end of the lower cylinder, and one end of the outer flange may be higher than the upper end of the lower cylinder. The axial section butt of interior flange is in the top of barrel down, and the radial section butt of interior flange is in the outward flange, and like this, one side that radial section was kept away from to the axial section can be located same curved surface with lower barrel. This provides a gentle climbing surface for the droplets. In addition, the outer flange and the inner flange are matched with each other and shield the gap from each other, so that the sealing performance between the upper section 122 and the lower section 123 can be improved conveniently. Lower cylinder outer flange lower cylinder upper cylinder inner flange radial section axial section outer flange axial section lower cylinder outer flange inner flange

It is worth mentioning that in order to achieve the tightness between the upper section 122 and the lower section 123, it is also possible to provide a sealing member between the lower section 123 and the upper section 122. Seals include, but are not limited to, o-rings, gaskets, and the like.

Alternatively, the angle between the side wall of the lower section 123 and the axis of the barrel 12 may be greater than the angle between the side wall of the upper section 122 and the side wall of the barrel 12. The water rises rapidly in the lower section 123, and the water can be easily separated from the supporting force or the adhesion force of the inner wall of the upper section 122 to the water in the upper section 122, and can be more easily thrown out of the water throwing holes 121. In addition, the variation of the inclination angle of the upper section 122 can also be considered from the opening size of the air inlet. It can be understood that the direction of the initial speed of the water thrown from the water throwing hole 121 away from the upper section 122 can be related to the section of the upper section 122, the direction of the initial speed influences the movement track of the water thrown away, and further influences the contact area of the water thrown away and the gas, and the quality of the water curtain formed by the water washing component can be improved by reasonably setting one or more of the position of the water throwing hole 121 on the cylinder 12, the rotating speed of the cylinder 12 and the cross section of the cylinder 12 at the position of the water throwing hole 121, so that the air purification effect is improved.

As shown in fig. 5, the upper end of the cylinder 12 may be open, and an upper cover 13 may be disposed on the upper end of the cylinder 12, and the upper cover 13 may be used to close the upper end opening of the cylinder 12. In addition, when the water in the cylinder 12 rises to the upper end surface of the cylinder 12 along with the rotation of the cylinder 12, the water can fall down by being blocked by the upper end surface, so that at least part of the water blocked by the upper end surface flows out of the water throwing holes 121, and the water yield of the water throwing holes 121 is increased.

Alternatively, the upper cover 13 may include a bottom wall and a side wall, the bottom wall of the upper cover 13 may abut against the upper end surface of the barrel 12, and the side wall of the upper cover 13 may be sleeved outside the barrel 12. The lower end surface of the side wall of the upper cover 13 is located above the water slinger hole 121 so as to block at least part of the water having a tendency to move upward. It will be appreciated that at least part of the water thrown from the water slinging holes 121 has a tendency to move upwards at an initial velocity, and this part of the water may have a trajectory above the dynamic range of the gas, and this part of the water may not come into contact with the gas, and the ability to intercept the water thrown from the water slinging holes 121 and moving towards the top of the tank 11 can be improved by providing a suitable flange on the side wall of the upper cover 13 extending away from the bowl 12. The intercepted water may fall onto the outer sidewall of the upper section 122 below the sidewall of the upper cover 13, and may be thrown out toward the inner sidewall of the water tank 11 by the centrifugal force along with the rotation of the upper section 122 to form a water curtain, so that the air purification effect may be improved.

Alternatively, the barrel 12 and the upper cover 13 may be formed as a single piece by injection molding or the like, and in this case, an upper water blocking protrusion may be provided above the water throwing hole 121, and the upper water blocking protrusion extends from the outer side wall of the barrel 12 toward the direction away from the barrel 12 so as to block at least part of the water having a tendency to move toward the top end of the water tank 11.

Alternatively, the upper end of the barrel 12 is open. The water slinging hole 121 of the cylinder 12 is served by an opening at the top end thereof, and the water slinging hole 121 may be provided or not provided on the side wall thereof. When the cylinder 12 is driven to rotate, the water sucked into the cylinder 12 ascends along the side wall thereof, and all or part of the ascended water can be thrown out from the top opening of the cylinder 12 and forms a water curtain.

Alternatively, as shown in fig. 4 and 5, a lower water blocking protrusion 14 may be further provided below the water slinging hole 121, and the lower water blocking protrusion 14 extends from an outer side wall of the barrel 12 toward a direction away from the barrel 12 so as to block water sprayed from the water slinging hole 121 moving toward the bottom of the water tank 11. It can be understood that the initial velocity of at least part of the water thrown from the water throwing hole 121 has a tendency to move toward the bottom of the water tank 11, on one hand, the movement track of the part of the water may be out of the movement range of the gas entering the water tank 11 from the air inlet, and the part of the water may not contact with the gas, and by providing the lower water blocking protrusion 14, a part of the water moving toward the bottom of the water tank 11 may be intercepted, and the intercepted water may be accumulated above the lower water blocking protrusion 14 and thrown out under the centrifugal force along with the rotation of the cylinder 12 to form a water curtain, thereby facilitating the improvement of the air purification effect; on the other hand, the water is easy to fall from the air inlet on the side wall of the water tank 11 to the outside of the water tank 11, and the water is prevented from splashing out of the water tank 11 from the air inlet to a certain extent by arranging the lower water blocking bulge 14.

As shown in fig. 2, an upper water blocking structure 15 for blocking an air outlet of the water tank 11 is disposed at the air outlet of the water tank 11, and the water thrown from the water throwing hole 121 can be blocked by the upper water blocking structure 15, so that the water cannot splash to the outside of the water tank 11 from the air outlet of the water tank 11. It should be noted that the water blocked by the upper water-retaining structure 15 may include water directly thrown out by the water-throwing holes 121, or may include water carried by gas passing through the water curtain.

Exemplarily, fig. 3 is an enlarged view of fig. 2 at a, and as shown in fig. 3, the upper water-retaining structure 15 includes a water-absorbing member 151, and the water-absorbing member 151 may be made of a material capable of blocking water droplets from passing through but allowing gas to pass through, such as a porous polymer material in the prior art. In some examples, the water absorbing member 151 may be made of a unidirectional water-blocking material, such as a reticulated polyurethane foam, a sponge, or the like.

In addition, in order to facilitate the installation and support the water absorbing member 151, the phenomenon that the water absorbing member 151 excessively drops after absorbing water is avoided, the upper water retaining structure 15 can further comprise a support frame, the support frame can be arranged in a hollow column shape, and the water absorbing member 151 can be installed inside the support frame. The support frame can be mounted on the top end of the water tank 11 by means of a screw connection, a snap connection or the like. For example, a placement groove 112 may be provided at the top end of the water tank 11, and the support frame may be embedded in the placement groove 112. Illustratively, the bottom wall of the placement groove 112 may be used to support the bottom wall of the support bracket, and the side wall of the support bracket may be in interference fit with the side wall of the placement groove 112 so as to circumferentially limit displacement of the support bracket.

The supporting frame may be provided in a net structure, and the supporting frame of the net structure may be installed at the top end of the water tank 11 in the same manner as the above-described hollow cylindrical supporting frame. By forming the supporting frame into a net structure, not only the supporting force of the supporting frame on the water absorbing member 151 can be improved, but also the passage of the purified gas is not affected. Alternatively, the mesh of the mesh structure may be hexagonal in order to improve the stability of the scaffold.

Alternatively, the support bracket may include a support section 152 and a cover section 153, the support section 152 may include a bottom wall and a side wall, and the side wall of the support section 152 may be connected to an outer circumference of the bottom wall of the support section 152 and extend upward. The cover section 153 may include a top wall and a side wall, and the side wall of the cover section 153 may be connected to the outer circumference of the top wall of the cover section 153 and extend downward. The sidewall of the supporting section 152 can be sleeved outside the sidewall of the covering section 153. The water absorbing member 151 may be located in a receiving space surrounded by a bottom wall of the supporting section 152, a side wall of the covering section 153, and a top wall of the covering section 153, such that a lower portion of the water absorbing member 151 is supported by the supporting section 152, an upper end of the water absorbing member 151 is covered by the covering section 153 to define an upper portion of the water absorbing member 151, and a circumferential direction of the water absorbing member 151 is defined by the side wall of the covering section 153 and the side wall of the supporting section 152 to maintain a structural shape of the water absorbing member 151 and to facilitate installation of the water absorbing member 151.

In addition, the supporting section 152 and/or the covering section 153 may have certain elasticity so as to improve the sealing performance between the side wall of the supporting section 152 and the side wall of the covering section 153, so as to block water from splashing out of the water tank 11 from between the side wall of the supporting section 152 and the side wall of the covering section 153. Furthermore, the sealing performance can be improved by arranging a sealing element between the two, or the sealing performance can be realized by the interference fit between the covering section 153 and the supporting section 152.

With continued reference to fig. 3, when the cover section 153 and the support section 152 are interference-fitted, the outer circumference of the top wall of the cover section 153 may be provided with a mounting groove, and the upper end of the side wall of the support section 152 may be connected with a mounting protrusion, which may be fittingly connected to the mounting groove. Illustratively, the mounting projection may be directed toward the axial direction of the support section 152, and a lower end surface of the mounting projection may be mounted against the bottom wall of the mounting groove so as to block the movement of the upper end of the cover section 153. Alternatively, the number of the mounting grooves may be one or more, and a plurality of mounting grooves may be uniformly arranged at the outer circumference of the cover section 153.

The power section 2 will be described below

Hereinafter, the structure shown in fig. 5 is taken as an example to explain the power unit 2 and the engagement manner with the cylinder 12, that is, the upper cover 13 is disposed above the power unit, and the sidewall of the upper cover 13 is sleeved outside the cylinder 12, and the case that the power unit 2 drives the cylinder 12 to rotate will be described. It should be understood, however, that the configuration of the barrel 12 is not limited to the configuration of fig. 5, and may be other configurations as noted above.

It is understood that the structure of the decelerator may include, but is not limited to, the above structure. By adopting the separable matching mode of the first bevel gear 23 and the second bevel gear 24, etc., the disassembly of the water tank 11 and the base 51 can be facilitated, thereby facilitating the cleaning and/or water adding of the water tank 11. Specifically, when the water tank 11 and the base 51 need to be separated, the first bevel gear 23 and the second bevel gear 24 need only be separated.

In addition, the motor shaft 221 may be coaxially connected to the first bevel gear 23. The shaft 21 includes a first end and a second end, the first end of the shaft 21 can be coaxially connected to the second bevel gear 24, and the second end of the shaft 21 can be connected to the cylinder 12. Referring to the drawings, the first end of the rotating shaft 21 may be a lower end of the rotating shaft 21, and the second end of the rotating shaft 21 may be an upper end of the rotating shaft 21. It can be understood that, after the motor 22 is powered on, the motor shaft 221 of the motor 22 can drive the first bevel gear 23 to rotate, the first bevel gear 23 can drive the second bevel gear 24 to rotate, and further drive the rotating shaft 21 connected to the second bevel gear 24 to rotate, so that the cylinder 12 connected to the rotating shaft 21 rotates, and the functions of water absorption, water pumping and water spraying of the cylinder 12 from the water tank 11 are realized.

The installation of the power section 2 will be described in turn from bottom to top.

Mounting of the motor 22:

as shown in fig. 5, the motor 22 may include a motor body 222 and a motor shaft 221, and the motor body 222 may be mounted on the base 51 in a suspended manner so as to reduce the influence of the vibration of the motor 22 on the components therebelow. Illustratively, a mounting claw 223 extending outward from the motor body 222 may be coupled to a sidewall of the motor body 222, and a fastening hole may be formed in the mounting claw 223, and a fastening member may be coupled to the base 51 through the fastening hole. Illustratively, a plurality of mounting claws 223 may be circumferentially arranged on the outer side of the motor main body 222, and the mounting claws 223 may be uniformly distributed on the outer circumference of the motor main body 222 so as to balance the force applied to the base of the motor 22. Fasteners include, but are not limited to, bolts, screws, and dowel pins. In addition, the base 51 may be thickened at the connection position with the fastener, so as to improve the bearing capacity of the base 51. For example, the base 51 may be provided with a connection column 511, an end of the connection column 511 away from the base 51 may abut against the mounting claw 223, and a fastener may pass through the through hole of the mounting claw 223 and connect to the connection column 511. The number of the coupling posts 511 may correspond to the number of the mounting claws 223.

Further, a vibration damping structure may be provided between the upper end of the motor main body 222 and the base 51 in order to reduce the influence of vibration generated by the motor 22 on the base 51. The vibration damping structure may include a first vibration damping sleeve, which may be located between the upper end of the motor body 222 and the lower end surface of the base 51. The first damping sleeve may be made of an elastic material such as rubber so as to be able to damp vibrations.

Mounting of the first helical gear 23:

as shown in fig. 5, the first bevel gear 23 is rotatably mounted above the base 51, and the motor shaft 221 can pass through the base 51 to be connected with the first bevel gear 23. Wherein, the upper end of the motor shaft 221 can be screwed to realize the installation of the motor shaft 221 and the first bevel gear 23. Illustratively, the motor shaft 221 may include a first section and a second section that are connected, the first section of the motor shaft 221 being connected to the motor body 222, and the second section of the motor shaft 221 being threadedly connected to the first beveled gear 23. The cross-sectional radius of a first section of the motor shaft 221 is greater than the cross-sectional radius of a second section of the motor shaft 221. The lower end of the first bevel gear 23 can abut against the upper end surface of the first section of the motor shaft 221 so as to prevent the first bevel gear 23 from moving downward. In addition, the rotation direction of the motor shaft 221 can make the first bevel gear 23 screw with the motor shaft 221, so that the motor shaft 221 can drive the first bevel gear 23 to rotate.

Optionally, a vibration damping structure may be provided between the first bevel gear 23 and the second bevel gear 24 in order to attenuate the effect of vibrations on the first bevel gear 23 on the second bevel gear 24. The damping structure may include a second damping sleeve, which may be fitted over the first helical gear 23 so as to increase a contact surface between the second damping sleeve and the first helical gear 23.

Mounting of the second helical gear 24:

as shown in fig. 5, the second bevel gear 24 may be mounted to a lower end of the water tank 11, wherein, in order to achieve the isolation of the power part 2 from the water in the water tank 11, a mounting recess 114 may be provided on a bottom wall of the water tank 11, the mounting recess 114 having a downwardly facing opening, and the second bevel gear 24 is at least partially mounted in the mounting recess 114. The mounting recess 114 extends inwardly toward the tank 11 and is located within the barrel 12.

Alternatively, in order to simplify the process and/or assembly, a bottom plate 115 may be installed at the bottom end of the water tank 11, and the bottom plate 115 may be provided with an insertion port 1151 coaxial with the installation recess 114. Illustratively, the base plate 115 is detachably attached to the water tank 11, for example, the base plate 115 and the water tank 11 are assembled together by screws.

The second helical gear 24 may be provided inside the insertion port 1151 so as to achieve modular installation. For example, a stopper plate 1152 may be disposed in the insertion port 1151, and the stopper plate 1152 and an area therebelow may define an installation space of the second helical gear 24. The second bevel gear 24 is rotatably disposed in the mounting space so as to restrict a movable area of the second bevel gear 24.

Based on the above, the insertion port 1151 is located outside the first bevel gear 23, so that the limit plate 1152, the insertion port 1151 and the base 51 can limit the moving area of the first bevel gear 23 and the second bevel gear 24, that is, the upper side of the second bevel gear 24 is limited by the limit plate 1152, and the lower side of the second bevel gear 24 is limited by the first bevel gear 23, so that the longitudinal movement of the second bevel gear 24 is limited, thereby preventing the second bevel gear 24 and the first bevel gear 23 from disengaging, and ensuring the reliability of the transmission.

The lower end of the rotating shaft 21 may be threadedly coupled to the second bevel gear 24. Illustratively, the motor 22 rotates the second bevel gear 24, and the second bevel gear 24 rotates in a direction such that the second bevel gear 24 and the rotating shaft 21 are screwed together, that is, the motor 22 drives the second bevel gear 24 in a direction opposite to a direction in which the rotating shaft 21 disengages from the second bevel gear 24, so that the second bevel gear 24 rotates the rotating shaft 21.

Fig. 6 shows a perspective view of a base body 5, fig. 8 shows a top view of a water box and a bottom plate, and as shown in fig. 6 and 8, a damping structure may be provided between the bottom plate 115 and the base 51, and the damping structure may include a third damping pad 63. A part of the vibration generated by the motor 22 is transmitted to the base 51, and since the third vibration damping pad 63 is located between the bottom surface of the water tank 11 and the top surface of the base 51, the third vibration damping pad 63 can attenuate energy caused by the vibration by deformation, thereby performing a vibration damping function. Alternatively, the third vibration dampening pad 63 includes, but is not limited to, a rubber pad, a spring, a resilient ball, a spring plate.

The base 51 is provided with a mounting hole, and the lower part of the third cushion 63 can be embedded in the mounting hole. The lower portion of the third cushion 63 may be interference fitted with the mounting hole to accomplish the mounting of the third cushion 63.

The number of the third vibration damping pads 63 is not limited, and may be one or more, for example, four third vibration damping pads 63 are shown in the drawings. For example, when there are two third damping pads 63, two third damping pads 63 may be arranged on both sides of the first or second bevel gear 23 or 24; when there are three third damping pads 63, the three third damping pads 63 may be distributed at three vertices of a triangle to facilitate the installation reliability of the water tank 11; when four third vibration damping pads 63 are provided, the four third vibration damping pads 63 may be located at four corners of the approximately rectangular base 51, respectively. Of course, the structure of the third damping pad 63 is not limited thereto, and the embodiment is only illustrated here.

It should be noted that when the third damping pad 63 is provided in plural, at least a part of the water tank 11 is inevitably suspended in the base 51, that is, at a position where the third damping pad 63 is not provided, the base 51 and the water tank 11 are not in contact, so that the possibility that the vibration on the base 51 is transmitted to the water tank 11 can be further reduced.

Optionally, a plurality of supporting protrusions 64 are provided on a side of the water tank 11 facing the base 51, and the supporting protrusions 64 are used for bearing the pressure of the water tank 11 on the third damping pad 63. Wherein, the third damping pad 63 and the supporting protrusion 64 may be disposed in a staggered manner. The support protrusion 64 may be connected to the bottom wall of the water tank 11, and a third vibration reduction pad 63 may be provided under the support protrusion 64 to reduce vibration at the contact of the support protrusion 64 and the base 51.

In addition, the height of the third vibration damping pad 63 in the axial direction of the water tank 11 may be equal to the height of the support protrusion 64 in the axial direction of the water tank 11. It should be noted that the third damping pad 63 is under the action of the gravity of the water tank 11, so that the deformation capability of the third damping pad 63 may be weakened after the third damping pad 63 is used for a period of time, and the pressure of the water tank 11 on the third damping pad 63 can be reduced by the support protrusion 64, so that the third damping pad 63 maintains its deformation capability to resist the vibration generated by the base 51.

Further, the support protrusion 64 may include a cylinder, one end of which may be connected to the bottom wall of the water tank 11, and the other end of which may abut on the upper end surface of the base 51. Alternatively, the support protrusions 64 may comprise a prism, the longitudinal section of which may be trapezoidal, the side wall of which gradually slopes towards the water tank 11 from the axis of the prism to the edge of the prism, i.e. the section of the prism near the water tank 11 is greater than the section of the prism near the base 51.

Alternatively, the support protrusion 64 may be one or more, for example, four support protrusions 64 are provided in fig. 8. For example, when there are two supporting protrusions 64, the two supporting protrusions 64 may be located at both sides of the first bevel gear 23 or the second bevel gear 24, and the two supporting protrusions 64 may be symmetrically arranged; when the number of the supporting protrusions 64 is three, the three supporting protrusions 64 may be distributed at three vertices of a triangle to facilitate the installation reliability of the water tank 11; when the number of the supporting protrusions 64 is four, the four supporting protrusions 64 may be respectively located at four vertices of the rectangle, and in some examples, at least two supporting protrusions 64 of the four supporting protrusions 64 may be symmetrically disposed. Of course, the structure of the support protrusion 64 is not limited thereto, and is only exemplified herein.

As shown in the figure, the base 51 is provided with a positioning protrusion 513, and a side of the water tank 11 facing the base 51 is provided with a first positioning recess 516 matched with the positioning protrusion 513, so as to achieve quick installation between the water tank 11 and the base 51. Alternatively, the positioning protrusion 513 has a conical shape, and the radius of the cross section of the positioning protrusion 513 gradually increases in a direction away from the water tank 11, so that the water tank 11 can be removed from the base 51 with less effort.

Optionally, at least two positioning protrusions 513 are disposed on the base 51, and the positioning protrusions 513 are respectively disposed on two sides of the second bevel gear 24. The vibration at the second helical gear 24 is large, the vibration can be transmitted in the vertical direction, the vibration can also be transmitted in the circumferential direction of the base 51, and when the vibration is transmitted to the positioning protrusion 513, the vibration can be attenuated by the height change of the transverse section of the positioning protrusion 513. In addition, a plurality of positioning projections 513 are provided, which can restrict the rotation of the water tank 11.

The oil seal 27 may seal the rotary shaft 21 from the ingress of dust, liquid, etc.

Optionally, the upper end of the mounting recess 114 may also be provided with a bearing 25 for radially supporting the rotary shaft 21. The upper end of the mounting recess 114 may also be provided with the above-mentioned gasket 26 and oil seal 27.

It should be noted that the bearing 25, the gasket 26 and the oil seal 27 on the mounting recess 114 and the insertion port 1151 may be symmetrically disposed.

As shown in fig. 5, a coupling member 28 may be provided between the upper end side wall of the rotational shaft 21 and the inner wall of the cylindrical body 12 so as to couple the rotational shaft 21 and the cylindrical body 12 together through the coupling member 28.

To improve the sealing performance, the sleeve 281 may be formed as a single piece with the bottom wall of the water tank 11 by means of integral molding such as injection molding.

The connecting piece 282 may be provided with one or more. When the connection piece 282 is provided in plural, the plural connection pieces 282 may be uniformly distributed in the circumferential direction of the rotation shaft 21 so as to improve the connection strength between the connection member 28 and the cylinder 12, and at the same time, the connection piece 282 may also play a role of supporting the cylinder 12 so as to improve the structural strength of the cylinder 12.

When the water tank 11 is to be taken out, the user can put his hand into the taking-out groove 515, hold the hand-holding protrusion 1153 upward, and pull it outward, so that the first bevel gear 23 and the second bevel gear 24 can be separated, and the water tank 11 and the base 51 can be easily separated.

Alternatively, as shown in fig. 1 and 8, the opposite sidewalls of the water tank 11 may be provided with hand-holding recesses 116, and the hand-holding recesses 116 may extend inwardly of the water tank 11. The user may also insert his or her hand into the hand-held depression 116 and pull the tank 11 outward when removing the tank 11.

Since the base 51 is used for carrying the water tank 11, the power unit 2 and the washing unit 1. Therefore, in order to improve the stability and structural strength of the base 51 for carrying the weight of the motor 22 and the water tank 11, the following base reinforcing structure can be used.

Excess water may overflow from the air inlet into the gap between the base body 5 and the water tank 11 and fall down the side walls of the base body 5 into the outlet aperture 722.

It should be noted that the air flow of the whole air cleaning device may be from the side surface and then flow out from the top surface or the side surface, or may be from the bottom surface and then flow out from the top surface or the side surface. The difference of air inlet mode leads to the difference of air inlet portion 3, and air inlet portion 3 relies on base member 5 to set up, so the shape that different air inlet mode correspond base member 5 can be different. Although the air intake method is different, the power unit 2, the water tank 11, and the water washing unit 1 may have the same configuration.

The base body 5 includes the above-mentioned base 51 and a base case, the base 51 can be used for installation of the power part 2, the water tank 11 and the water washing part 1, and the base case is used for installation of the air inlet part 3.

The filter layer 311 may be disposed outside the air inlet of the water tank 11, and the filter frame 312 may be disposed outside the filter layer 311. When the water tank 11 is mainly formed by connecting the arc portion and the vertical portion, the air inlet may be disposed on the arc portion, and the primary filter assembly 31 is disposed outside the arc portion of the water tank 11. For convenience of description, hereinafter, an arc-shaped portion of the water tank 11 is defined as a front end of the water tank 11, and a vertical portion of the water tank 11 is defined as a rear end of the water tank 11.

It is understood that the filter frame 312 may have through holes, so that the external air enters from the through holes and passes through the filter layer 311 for primary filtering, and then enters the water tank 11 from the air inlet of the water tank 11 and is purified by the water curtain. For example, the filter holder 312 may include a side wall, an upper wall, and a bottom wall, and the upper wall of the filter holder 312 and the bottom wall of the filter holder 312 are respectively connected to both ends of the side wall of the filter holder 312, and may both extend toward the axial direction of the water tank 11. The side walls, the upper wall, and the bottom wall of the filter holder 312 define a mounting space for mounting the filter layer 311.

Alternatively, as shown in fig. 1 and 11, the upper wall of the filter holder 312 may be connected to the upper end of the water tank 11. Illustratively, the sidewall of the upper end of the water tank 11 is stepped to form a placement groove 112 for connecting the upper water-retaining structure 15. It will be appreciated that the bottom wall of the placement recess 112 may abut the upper wall of the filter holder 312 so as to limit the longitudinal height of the filter holder 312.

Alternatively, as may be taken in continuing reference to fig. 1 and 11, the bottom wall of the filter holder 312 may be attached to the upper end face of the first base shell 53, and the first base shell 53 may be used to support the filter holder 312. In addition, the length of the bottom wall of the filter holder 312 may exceed the thickness of the filter layer 311 in the radial direction. That is, the bottom wall of the filter holder 312 is at least partially uncovered by the filter layer 311. The outer side wall of the water tank 11 may be connected with a limiting plate 101, and the limiting plate 101 may abut against an upper end surface of a portion of the bottom wall of the filter holder 312, which exceeds the filter layer 311, so as to achieve positioning of the filter holder 312 in the longitudinal direction. In addition, an abutting protrusion 102 may be connected to a sidewall of the water tank 11, the abutting protrusion 102 may extend toward an outer side of the water tank 11, and the abutting protrusion 102 may abut on one side in a thickness direction of the filter layer 311. It is understood that the sidewall of the filter holder 312 and the abutment projection 102 may limit the displacement in the thickness direction of the filter layer 311.

Alternatively, referring to fig. 6 and 7, the upper end surface of the front end of the first base shell 53 may be provided with a limiting protrusion 531, and an inner wall of the limiting protrusion 531 may abut against an outer side wall of the front end of the filter holder 312 so as to limit the radial direction of the filter holder 312. For example, the filter frame 312 and the filter layer 311 may be designed in an arc shape, and the shape of the defining protrusion 531 may match the shape of the filter layer 311 so as to be attached to the outer sidewall of the filter frame 312.

Alternatively, the limiting protrusion 531 may be provided with a positioning hole 532. The outer side wall of the filter frame 312 may be connected with a positioning plate 313, and the positioning plate 313 may extend in an axial direction away from the water tank 11. The positioning plate 313 can be fittingly connected to the positioning hole 532. Illustratively, at least a portion of the positioning plate 313 may be inserted into the positioning hole 532. It will be appreciated that when the filter holder 312 is mounted to the first base shell 53, the positioning plate 313 is only required to extend out of the positioning hole 532, which facilitates the positioning and mounting of the filter holder 312. In addition, the positioning hole 532 may be disposed toward a direction parallel to or coincident with the symmetry axis of the first base housing 53, so that when the filter holder 312 is mounted, the positioning plate 313 on the filter holder 312 is pushed in the direction to pass through the positioning hole 532, thereby achieving quick mounting.

Alternatively, as can be seen by continuing to refer to fig. 5 and 9, a limiting recess 533 may be disposed on the upper end surface of the rear end of the first base shell 53, and an insertion protrusion 314 may be disposed on the bottom wall of the filter holder 312, and the insertion protrusion 314 may be fittingly connected to the limiting recess 533. Illustratively, the plugging protrusion 314 may include a vertical section connected to the bottom wall of the filter holder 312, and a horizontal section bent toward the front end of the filter holder 312 with respect to the vertical section. The upper end of the limiting recess 533 may be open, the limiting recess 533 includes a groove wall and a groove bottom, the groove wall of the limiting recess 533 at the front end may be provided with a socket 534, and the horizontal section of the inserting protrusion 314 may be inserted into the socket 534, so as to limit and mount the filter frame 312. It will be appreciated that the horizontal segment of the plugging projection 314 can slide on the bottom of the groove defining the recess 533 to limit the movement trajectory of the filter holder 312.

Optionally, the top surface of the front end of the first base housing 53 is provided with a front protrusion 535, and the bottom wall of the filter holder 312 may be provided with a groove that fits into the front protrusion 535, so as to at least partially restrict the forward and backward movement of the filter holder 312. In some examples, the front protrusion 535 has a gradually increasing cross-section from top to bottom, i.e., the front protrusion 535 is generally conical.

Optionally, the first base shell 53 may be provided with a storage recess 536 (an opening is also provided on the corresponding surface of the base 51) for installing the controller 182 of the water shortage prompting device, and the bottom wall of the filter holder 312 may be used for shielding the storage recess 536 so as to limit the electric wires connected to the controller 182. The first base housing 53 may be provided with a wire hole 537 for routing a cable.

With respect to the air outlet portion 4:

as shown in fig. 11, the air outlet portion 4 may include an air outlet housing 41, the air outlet housing 41 may be disposed in a hollow manner, and an opening communicated with the upper end of the water tank 11 may be disposed at the lower end of the air outlet housing 41. A fan may be provided in the hood 41 to direct air into the tank 11 and through the water curtain formed in the tank 11. An air outlet is arranged on the air outlet cover 41 so as to lead out air conveniently.

Illustratively, the type of fan may be centrifugal, axial, diagonal (mixed) or cross flow, etc. Fig. 1 illustrates a centrifugal fan as an example, and other types of fans can be referred to. The centrifugal fan 431 may include an impeller 4311 and a centrifugal motor 4312 for driving the impeller 4311. Wherein the impeller 4311 may comprise a hub and a fan. It is understood that when the centrifugal motor 4312 is turned on, the impeller 4311 rotates, and the air in the flow channel (two adjacent fan blades can form a flow channel) moves outwards under the action of centrifugal force, so as to generate a vacuum in the center of the impeller 4311. Therefore, the gas coming out of the upper opening of the water tank 11 is sucked into the impeller 4311, and the sucked gas is turned by 90 ° at the inlet of the impeller 4311 and enters the flow passage to obtain kinetic energy and pressure energy under the action of the fan blades. The air flow thrown out from the flow channel enters the air outlet housing 41, and is discharged from the air outlet of the air outlet housing 41 after centralized flow guiding.

It is understood that the fan blades can be disposed in an inclined manner, and the inclined direction of the fan blades can be opposite to the rotation direction of the impeller 4311. The following description is given by taking the case where the fan 43111 is disposed clockwise and the impeller 4311 rotates counterclockwise. Here, the rotation direction of the impeller 4311 can also be clockwise, and when the impeller 4311 rotates clockwise, the arrangement mode of the air outlet cover 41 can refer to

As shown in fig. 1 and fig. 11, to facilitate installation of the blower, the air-out housing 41 may include an upper housing 433 and a lower housing 432, and the upper housing 433 may be detachably connected to the lower housing 432. The lower cover 432 may have a center hole formed therethrough, and the lower end of the center hole may be connected to the upper opening of the water tank 11.

The structure of the lower cover 432 will be described below from bottom to top.

As shown in fig. 1 and 11, the lower housing 432 may include a mounting portion for connecting to the water tank 11 and/or the filter holder 312, and a guiding portion for guiding a flow direction of the gas in the air-out housing 41. For example, fig. 12 is a schematic view illustrating a connection position of a portion of the water tank 11 and the lower cover 432, and as shown in fig. 11 and 12, the mounting portion may include a first mounting section 4321, and the first mounting section 4321 may be annularly disposed and may be sleeved on an outer side wall of an upper end of the water tank 11. A vibration damping structure may be provided between an upper end outer sidewall of the water tank 11 and an inner wall of the first mounting section 4321, and the vibration damping structure may include a vibration damping packing 65 in order to reduce noise at a connection position of the first mounting section 4321 and the water tank 11. In addition, the vibration-damping packing 65 may also serve as a seal to block the washing liquid thrown out from flowing to the outside of the lower housing 432.

In addition, when the sidewall of the water tank 11 is provided with the primary filter assembly 31, the mounting portion may further include a second mounting section 4322, the second mounting section 4322 may include a sidewall and an upper wall, the upper wall of the second mounting section 4322 may be bent toward an outer side with respect to the first mounting section 4321 (herein, "outer side" refers to an outer side of the lower shield 432), and the sidewall of the second mounting section 4322 may be bent toward a lower side with respect to the upper wall of the second mounting section 4322. The upper wall of the second mounting section 4322 can abut against the upper end surface of the filter frame 312, and the sidewall of the second mounting section 4322 can be sleeved on the outer side of the upper end of the filter frame 312. In this way, the upper and lower ends of the filter holder 312 are respectively limited by the upper wall of the second mounting section 4322 and the upper end surface of the first base shell 53, and the inner and outer sides of the filter holder 312 are respectively limited by the side walls of the water tank 11 and the second mounting section 4322, so that the limitation of the second mounting section 4322 to the height direction of the filter holder 312 and the limitation to the thickness direction of the filter holder 312 (i.e., the radial direction of the filter holder 312) are achieved.

Further, as shown in fig. 1, a first reinforcing plate 4341 may be provided between the upper walls of the first and second mounting sections 4321 and 4322 to reinforce the connection between the first and second mounting sections 4321 and 4322.

Alternatively, as shown in fig. 11, the guide portion may include a concentration plate 4323 connected to the outer periphery of the upper end of the first installation section 4321, and the concentration plate 4323 may be provided with a concentration hole penetrating therethrough, and the concentration hole may correspond to an air inlet of the impeller 4311. The gas entering the first mounting section 4321 can pass through the concentrating holes to reduce the radius of the cross-sectional area of the lower housing 432, so that the gas is concentrated toward the air inlet of the impeller 4311, which facilitates the gas entering the impeller 4311.

The guide portion may further include a first guide protrusion 4324 provided in a ring shape, and the first guide protrusion 4324 is located below the impeller 4311, may be connected to a circumferential direction of the concentration hole, and may be bent toward an inside of the impeller 4311, so as to guide the purified gas into the impeller 4311 of the centrifugal fan 431. Wherein at least a portion of the first guide projection 4324 is embedded in the impeller 4311 of the centrifugal fan 431, so as to facilitate smooth butt joint between the radial section of the first guide projection 4324 and the impeller 4311. It is understood that the first mounting section 4321, the concentrating plate 4323, and the first guide projection 4324 may define a first guide air passage.

In addition, fig. 13 shows a transverse sectional view of fig. 1 at a middle position of the first air outlet 43281, and as shown in fig. 11 and 13, an equalizing plate 4325 may be connected to an upper end inner wall of the first guide projection 4324 to disperse the air into several regions so as to achieve uniform air outlet. The term "uniform outlet" refers to that the flow rate of the gas in the same radial position can be the same. Illustratively, the equalization plate 4325 may include a circumferential rim 43251 and a radial rim 432542. The circumferential rim 43251 may be annularly disposed, may be located within the first guide projection 4324, and may be concentrically disposed with the first guide projection 4324. The radial rim 432542 may be disposed radially of the first guide projection 4324 and may connect the first guide projection 4324 and the circumferential rim 43251 together to form several regions.

It will be appreciated that, as shown in FIG. 11, the hub of the centrifugal fan 431 may include an air intake section for introducing air and a connection section above the air intake section for mounting the centrifugal motor 4312. The air inlet section and the connecting section can be connected through the fan blades. Wherein the air intake section is gradually bent toward the outside of the impeller 4311 from the top to the bottom to guide the gas to the outside of the impeller 4311.

As shown in fig. 11, the lower cover 432 may be designed as follows in order to be more closely attached to the air inlet section of the centrifugal fan 431 or to guide the gas to the outside of the impeller 4311. For example, the guide portion may include a second guide protrusion 4326, the second guide protrusion 4326 may be annularly disposed, and the second guide protrusion 4326 may be sleeved outside the air inlet section of the hub, may be connected to the concentration plate 4323, and may be bent toward the outside of the impeller 4311. The second guide protrusion 4326 and the air intake section of the hub define a second guide passage 422 therebetween.

For example, the second guide projection 4326 may include an axial section and a radial section, and the axial section of the second guide projection 4326 may be connected to and converge on the plate 4323 and extend upward. The radial section of the second guide projection 4326 may be bent toward the outside of the impeller 4311 with respect to the axial section of the second guide projection 4326. The air intake section of the hub may be located between the first guide projection 4324 and the second guide projection 4326.

In addition, the concentration plate 4323 located between the air inlet section of the hub and the second guide projection 4326 may be provided with an air outlet hole 43231. It is understood that a portion of the gas from the water tank 11 passes through the gas outlet 43231 and enters the second guide channel 422, and another portion of the gas from the water tank 11 enters the impeller 4311 through the first guide channel and joins the gas flowing out of the second guide channel 422 through the flow channel of the impeller 4311.

Optionally, the guide portion may further include a third guide projection 4327 and a fourth guide projection 4328, and the third guide projection 4327 may be connected to the second guide projection 4326 and extend toward the outer side of the lower cover 432. The fourth guide projection 4328 may be bent upward with respect to the third guide projection 4327, and the fourth guide projection 4328 may be provided with a first air outlet 43281. The third guide protrusion 4327 and the fourth guide protrusion 4328 may limit the third guide channel 423 to guide the gas out of the wind housing 41 from the first wind outlet 43281. In addition, the upper end of the first air outlet 43281 on the lower cover 432 can be opened, and the height of the opening of the first air outlet 43281 can be greater than the height of the flow channel of the impeller 4311, so as to ensure that the air flowing out of the flow channel of the impeller 4311 can smoothly enter the first air outlet 43281.

Alternatively, as shown in fig. 1, 11 and 13, there may be one first air outlet 43281, or there may be more than one first air outlet 43281. The first air outlet 43281 is commonly provided and will not be described in detail herein. As shown in fig. 11, when the first air outlet 43281 is provided in plurality, the fourth guide protrusion 4328 between two adjacent first air outlet 43281 is curved in a direction gradually away from the outer circumference of the impeller 4311 from one first air outlet 43281 to the other first air outlet 43281 along the rotation direction of the impeller 4311, so as to gradually guide the flow direction of the gas and reduce the energy loss between the gas and the fourth guide protrusion 4328. In addition, the first air outlet holes 43281 may be symmetrically arranged to balance the flow of air, so that the water washing air is stable.

It can be understood that the washing air purification device of the present application can be applied to floor type air conditioning equipment, so that the washing air purification device is suitable for the requirement of the user on the air outlet height, and the air outlet position of the air outlet cover 41 can be adjusted upwards to enlarge the air outlet height. For example, as shown in fig. 1 and 11, the fourth guiding protrusion 4328 may be provided with a side guiding recess 43282, the side guiding recess 43282 may extend towards the outer side of the lower cover 432, the side guiding recess 43282 may be provided with a second air outlet 43283, and the air outlet height of the second air outlet 43283 may be higher than the air outlet height of the first air outlet 43281. Here, the bottom wall of the side guide recess 43282 may be gradually inclined upward from the axis of the lower cover 432 to the outer circumferential direction of the lower cover 432, so as to guide the gas located in the third guide path 423 upward. It is understood that the side wall of the side guide recess 43282 and the bottom wall thereof may define a fourth guide channel 424, and the fourth guide channel 424 may communicate with the third guide channel 423, may guide the gas upward, and may flow out from the second air outlet 43283.

In addition, as shown in fig. 1, a rising plate 43284 may be further provided in the first air outlet 43281, and the rising plate 43284 is gradually inclined upward in the rotation direction of the impeller 4311, so as to obtain air moving obliquely upward. The raising plates 43284 can be uniformly distributed in the height direction of the first air outlet 43281 to uniformly discharge air.

Alternatively, as shown in fig. 13, the adjacent first and second air-out holes 43281 and 43283 may be curved toward a direction gradually away from the outer circumference of the impeller 4311 along the rotation direction of the impeller 4311 from one first air-out hole 43281 (or the second air-out hole 43283) to the other second air-out hole 43283 (or the first air-out hole 43281).

Alternatively, as shown in fig. 1, a reinforcing structure may be connected to the outer side of the second guide projection 4326, the reinforcing structure may be a second reinforcing plate 54344342, and the upper end to the lower end of the second reinforcing plate 54344342 may be connected to the third guide projection 4327 and the first guide projection 4324, respectively, so as to improve the load-bearing capacity of the lower cover 432.

Alternatively, as shown in fig. 13, the first air outlet 43281 and the second air outlet 43283 on the upper housing 433 may be symmetrically arranged, and two first air outlet 43281 or two second air outlet 43283 may be arranged on two sides of the symmetry axis, so as to improve the balance of the air outlet housing 41. For example, two second outlet vents 43283 may be located at the front end of the lower cover 432, and two first outlet vents 43281 may be located at the rear end of the lower cover 432. The front end of the lower cover 432 is aligned with the front end of the water tank 11, and the rear end of the lower cover 432 is aligned with the rear end of the water tank 11.

In order to obtain the above-mentioned symmetry requirement, between two adjacent first air outlet holes 43281 (or between the first air outlet hole 43281 and the second air outlet hole 43283), the fourth guiding projection 4328 may have a corresponding curve turning change. The fourth guiding projection 4328 between the two first air outlet holes 43281 will be briefly described. A first air inlet can be defined between two adjacent parallel fourth guide protrusions 4328.

For example, the first air outlet 43281 may include a first end and a second end, and the first end may be located before the second end in the rotation direction of the impeller 4311. As shown in fig. 12, the second end of the right first air-out hole 43281 can be connected to the first end of the left first air-out hole 43281 through the fourth guide projection 4328. Wherein the fourth guide projection 4328 may include a first straight section 43285, an arc section 43286 and a second straight section 43287, the first straight section 43285 may be connected to the second end of the first air-out hole 43281 at the right side, the second straight section 43287 may be connected to the first end of the second air-out hole 43283, and the first straight section 43285 and the second straight section 43287 may be symmetrically disposed so as to determine the symmetry reference of the two symmetrical first air-out holes 43281; the arc may include a first end and a second end, the first end of the arc segment 43286 may be connected to the second straight segment 43287 against the direction of rotation of the impeller 4311, the second end of the arc segment 43286 may be curved toward progressively closer to the impeller 4311, and the second end of the arc segment 43286 may be lower than the first end of the arc segment 43286. So that as the impeller 4311 rotates, the air can smoothly enter the first air outlet 43281 on the left side; the second end of the arc-shaped section 43286 and the first straight section 43285 may have a transition section 43288 to facilitate smooth entry of gas into the right first outlet 43281.

Alternatively, as can be seen from fig. 13, the transition 43288 has a distinct discontinuity, i.e. a distinct angular change, so that in order to increase the structural strength of the fourth guide projection 4328 at the location of the transition 43288, i.e. at the location of the cross-sectional discontinuity, the guide portion may further comprise a transition plate, which may connect the transition 43288 and the at least partially curved section 43286.

The upper shell 433 is described below:

as shown in FIGS. 1 and 11, the upper housing 433 may include an upper housing plate 4331, and the upper housing plate 4331 may be used to cover the central aperture of the lower housing 432. The fan can be suspended on the upper housing 433 to reduce the influence of the vibration of the fan on the air-out housing 41. The upper and lower shields 433 and 432 may be coupled by a fastener, and for example, the upper end of the fourth guide projection 4328 of the lower shield 432 may be coupled with a lower shield plate 4329, and the lower shield plate 4329 may extend toward the outside of the impeller 4311. The lower ends of at least some of the upper housing plates 4331 may abut the upper end of the lower housing plates 4329 and may be connected together by fasteners.

In addition, a lower cover flange 43291 may be connected to the lower cover plate 4329, the lower cover flange 43291 may extend upward, and a predetermined gap may be provided between the lower cover flange 43291 and the fourth guide protrusion 4328. The sidewalls of the upper housing plate 4331 may be embedded within the lower housing flange 43291 to limit movement of the upper housing plate 4331. In addition, an upper cover flange 43311 may be attached to the outer circumference of the upper cover plate 4331 to reinforce the structural strength of the upper cover plate 4331. The upper cover flange 43311 may extend upward and be embedded within the lower cover flange 43291.

In addition, a fastening projection 43292 may be coupled to a lower end of the lower cover plate 4329, and a fastening member may sequentially pass through the upper cover plate 4331 and the lower cover plate 4329 and be screw-coupled to the fastening projection 43292.

Alternatively, as shown in fig. 11, the upper housing plate 4331 may be provided with an upper guiding recess 4332, and the upper guiding recess 4332 may extend upward to increase the outlet height and area of the first outlet hole 43281 and/or the second outlet hole 43283. For example, the upper guide recess 4332 may include a first end and a second end, and the height of the upper guide recess 4332 gradually increases in a direction in which the impeller 4311 rotates. That is, the height of the second end of the upper guide recess 4332 is higher than the height of the first end of the upper guide recess 4332. The second end of the upper guiding recess 4332 may be open and connected to the first air outlet 43281 and/or the second air outlet 43283. Wherein each of the first air outlet 43281 and/or the second air outlet 43283 is connected with a corresponding upper guiding recess 4332.

It is understood that when the upper guide recess 4332 is not provided, the upper housing plate 4331, the third guide projection 4327 and the fourth guide projection 4328 define the third guide path 423, and the first air outlet 43281 and/or the second air outlet 43283 have a height that is lower than a height between the upper housing plate 4331 and the third guide projection 4327. When the upper guide recess 4332 is provided, the gas can be guided upward, and the height of the first air outlet 43281 and/or the second air outlet 43283 can be increased.

Alternatively, fig. 14 shows a partial cross-sectional view of fig. 10 at N-N, and as shown in fig. 10, 11 and 14, a connection pad 66 may be provided between the blower and the upper housing 433, and the connection pad 66 may be made of a rubber material so as to have a vibration damping effect. When the blower is assembled, the fastener may be used to sequentially pass through the upper housing 433 and the connection pad 66 to connect with the blower.

Optionally, an upper recess extending upward may be disposed on the upper housing 433, and at least a portion of the blower may be embedded in the upper recess, so as to position the blower via the upper recess.

Alternatively, the upper end of the upper housing 433 may be provided with a positioning groove, and the connecting pad 66 may be connected with a positioning flange 661, which may extend toward the upper housing 433 and into the positioning groove. The outer side wall of the positioning flange 661 can abut against the groove wall of the positioning groove.

It is worth noting that the difficulty in determining the relative position of the blower with respect to the upper housing 433 can be reduced by the shape design of the positioning slot. For example, the positioning groove may have an asymmetric shape, or the positioning groove may have a symmetric shape, for example, the positioning groove may have a cross shape.

Illustratively, as shown in fig. 14, a reinforcing column 662 may be connected to the connecting pad 66, and at least two through holes may be formed in the upper housing 433.
