In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention.

For convenience of description, in the present embodiment, the direction indicated by the arrow X in the drawing is left, and the other direction is right; the direction pointed by the arrow Y is front, and the other direction is back; the direction indicated by the arrow Z is up, and the other direction is down.

Example one

Fig. 2 is a perspective view of an air cleaner according to an embodiment of the present invention, and fig. 3 is a partially exploded view of fig. 2. As shown in fig. 2 and 3, an air cleaner according to an embodiment of the present invention includes a base housing 30, a blower (not shown) installed in the base housing 30, a water tank 10 drawably installed in the base housing 30, and a water slinger assembly 12 rotatably disposed in the water tank 10. Wherein, the fan can be supplied power by external power supply or battery. The side wall of the base housing 30 is provided with an opening through which the water tank 10 can be drawn out of the base housing 30. In fig. 3, an opening is provided on the right side of the base housing 30, and the water tank 10 can be drawn out from the right opening of the base housing 30 in the drawing direction indicated by the arrow X.

The above-mentioned "the water slinging assembly 12 is rotatably disposed in the water tank 10" means that the water slinging assembly 12 is located in the water tank 10, and the water slinging assembly 12 can rotate relative to the water tank 10 under the driving of the driving source when the air purifier is in operation. During the rotation of the hydro slinger assembly 12, water in the tank 10 can be lifted to form a water curtain. The blower can guide the air outside the base housing 30 to enter the water tank 10 through the air inlet of the base housing 30 and the air inlet of the water tank 10 in sequence. The air introduced into the water tank 10 is mixed with the water curtain formed by the hydro-extracting assembly 12 to purify and humidify the air. The purified and humidified air sequentially flows out of the base housing 30 through the air outlet of the water tank 10 and the air outlet of the base housing 30. In this way, the purification and humidification of the air is completed.

The above-mentioned "water container 10 in which the water container 10 is drawably mounted in the base housing 30" means that the base housing 30 and the water container 10 are two independent members. The two can be connected by means of a snap connection. In operation of the air cleaner, the water tank 10 is fitted in the base housing 30, and the water tank 10 is stationary with respect to the base housing 30. In the case where the water level in the water tank 10 is low or the water tank 10 needs to be washed, etc., the air cleaner stops operating, and the user releases the connection between the water tank 10 and the base housing 30, so that the water tank 10 slides with respect to the base housing 30. And by pulling the tank 10, the tank 10 comes out of the opening of the base housing 30.

As shown in fig. 3, the base housing 30 includes an upper housing 302 and a lower housing 301. The upper end of the lower case 301 is open, and the upper case 302 covers the upper side of the lower case 301 and can cover the upper end opening of the lower case 301. Alternatively, a downwardly extending flange may be connected to the lower end of the upper casing 302, and a groove matched with the flange may be provided at the upper end of the lower casing 301, so that an operator can assemble the upper casing 302 and the lower casing 301. The above-mentioned side walls of the base case 30 are side walls of the lower case 301, and the above-mentioned bottom wall of the base case 30 is a bottom wall of the lower case 301. In fig. 3, the right side of the base housing 30 is provided with an opening, and the side walls of the base housing 30 may include a front side wall, a rear side wall, and a left side wall between the front side wall and the rear side wall, which are oppositely disposed.

Fig. 4 is a partial longitudinal sectional view of a section where the base housing 30 of fig. 2 is engaged with the water tank 10, and as shown in fig. 4, the base housing 30 is provided with a mounting recess 103, and the mounting recess 103 is provided with an opening toward the outside of the base housing 30. The outer side of the water tank 10 is provided with a slide rail 32 arranged along the drawing direction of the water tank 10, the slide rail 32 is in fit connection with the mounting recess 103, so that the water tank 10 slides in the base housing 30 along a preset track, and the distance between the front wall of the water tank 10 and the front wall of the base housing 30 and the distance between the rear wall of the water tank 10 and the rear wall of the base housing 30 are determined.

Fig. 5 is another schematic view of the base housing 30 in fig. 3, and as shown in fig. 5, the bottom wall of the base housing 30 is provided with a limiting protrusion 33, and the limiting protrusion 33 extends toward the inside of the base housing 30. Fig. 6 is another schematic view of the water tank 10 in fig. 3, and as shown in fig. 6, the bottom wall of the water tank 10 is provided with an avoiding groove 13 oriented along the drawing direction of the water tank 10, and the avoiding groove 13 is used for avoiding the limiting protrusion 33; the avoiding groove 13 is provided with a matching part 14, and the matching part 14 is used for being clamped and connected with the limiting bulge 33 when the water tank 10 is installed in the base shell 30.

Specifically, the escape groove 13 is provided in the bottom wall of the water tank 10, and the longitudinal direction of the escape groove 13 is the drawing direction of the water tank 10, in other words, the escape groove 13 extends in the drawing direction of the water tank 10. The depth direction of the avoiding groove 13 is the extending direction of the limiting protrusion 33, i.e. the direction of the arrow Z. When the water tank 10 is in the base shell 30, the distance from the upper end of the avoiding groove 13 to the bottom wall of the base shell 30 is smaller than the distance from the upper end of the limiting protrusion 33 to the bottom wall of the base shell 30, so that the surface of the water tank 10 and the limiting protrusion 33 are prevented from being squeezed, and the avoiding groove 13 can avoid the limiting protrusion 33. In addition, the left end of the escape groove 13 is open so that the stopper protrusion 33 passes through. In fig. 3, the water tank 10 is pushed into the base housing 30 from the opening of the right side wall of the base housing 30, and the left end of the avoiding groove 13 first passes through the limiting protrusion 33, so that the left end of the avoiding groove 13 is opened.

In addition, the fitting portion 14 is provided in the escape groove 13, and a lower end of the fitting portion 14 is flush with a lower end of the escape groove 13 (a lower surface of the water tank 10) or is located at an upper end of the lower end of the escape groove 13 (a lower surface of the water tank 10).

The engagement of the engaging portion 14 with the stopper projection 33 means that, after the water tank 10 is mounted on the base case 30, the stopper projection 33 is fitted into the engaging portion 14, and movement of the water tank 10 with respect to the base case 30 is restricted by restricting movement of the engaging portion 14 with respect to the stopper projection 33.

Alternatively, fig. 7 is an enlarged view of fig. 5 at a, and an arrow in fig. 7 indicates a moving trajectory of the engaging portion 14 above the stopper projection 33 when the water tank 10 is pushed into the base housing 30, and referring to fig. 7, in order to facilitate the engaging portion 14 to engage with the stopper projection 33, an end of the stopper projection 33 near the opening of the base housing 30 is inclined with respect to the bottom wall of the base housing 30. That is, in fig. 7, the water tank 10 is pushed into the base housing 30 from right to left, and when the fitting portion 14 is located on the right side of the limiting protrusion 33, the left end of the fitting portion 14 needs to cross the right end of the limiting protrusion 33 to reach the left end of the limiting protrusion 33, in order to reduce the resistance of the left end of the fitting portion 14 passing through the right end of the limiting protrusion 33, the right surface of the limiting protrusion 33 is inclined upward to the left, that is, the left included angle between the right surface of the limiting protrusion 33 and the bottom wall of the base housing 30 is an acute angle. The smaller the angle of the acute angle, the easier the left end of the fitting portion 14 passes over the right surface of the stopper projection 33.

In order to smoothly drop the left end of the engaging portion 14 from the upper vertex of the right surface, the end of the limiting protrusion 33 away from the opening of the base housing 30 is also inclined relative to the bottom wall of the base housing 30. That is, in fig. 7, when the left end of the engaging portion 14 is at the highest point of the limiting portion, in order to make the engaging portion 14 descend gently from the highest point of the limiting portion, the left surface of the limiting protrusion 33 inclines upward to the right, that is, the right-side included angle between the left surface of the limiting protrusion 33 and the bottom wall of the base shell 30 is an acute angle. The smaller the angle of the acute angle, the more gently the left end of the engaging portion 14 slides down along the left surface of the stopper protrusion 33.

In fig. 7, the left and right ends of the stopper projection 33 are inclined toward the middle of the stopper projection 33. That is, the cross section of the stopper protrusion 33 is gradually reduced from bottom to top. The limiting protrusion 33 may be a triangular protrusion, and an included angle between a right surface of the triangular protrusion and the bottom wall of the base shell 30 is smaller than an included angle between a left surface of the triangular protrusion and the bottom wall of the base shell 30. So that the water container 10 does not easily get over the left surface of the stopper protrusion 33 after being mounted to the base housing 30, i.e., the water container 10 does not easily move toward the left end.

Alternatively, the stopper projection 33 is elastically deformable in a direction perpendicular to the bottom wall of the base housing 30. That is, the stopper projection 33 is deformable in the direction of the arrow Z so that the left end of the fitting portion 14 easily passes over the stopper projection 33 to the left when the water tank 10 is pushed into the base housing 30; or to facilitate the left end of the fitting part 14 to easily pass over the stopper protrusion 33 to the right when the water tank 10 is withdrawn from the base housing 30. Of course, the water tank 10 can pass through the limit projection 33 more smoothly.

The position-limiting protrusion 33 may have elasticity itself, or may be disposed on the base housing 30 that can be elastically deformed. Referring to fig. 5 and 7, the bottom wall of the base housing 30 is provided with a U-shaped ring groove 31, and a stopper protrusion 33 is provided at the bottom of the ring groove 31. Specifically, the bottom surface of the stopper projection 33 is connected to the bottom wall of the base housing 30, and the base housing 30 outside the stopper projection 33 is provided with a U-shaped ring groove 31. The groove bottom of the U-shaped annular groove 31 is arranged at the left end or the right end of the limiting bulge 33. In fig. 7, the U-shaped ring groove 31 includes two opposite first sections disposed along the drawing direction of the tank 10 and a second section disposed between the two first sections. The second section is the bottom of the U-shaped ring groove 31. In fig. 7, the groove bottom of the U-shaped groove is provided at the left end of the stopper protrusion 33 so that the user pulls the water tank 10 rightward.

Several possible implementations of the mating portion 14 are described below:

in one possible implementation of the engaging portion 14, the engaging portion 14 may be a positioning block protruding downward from the bottom wall of the water tank 10. The bottom surface of the positioning block can be provided with a clamping groove which can be connected with the limiting bulge 33 in a clamping way.

That is, the positioning block is solid and is disposed in the escape slot 13. One end of the positioning block is connected with the bottom of the avoiding groove 13, and the other end of the positioning block extends downwards. The bottom surface of the positioning block is flush with or higher than the bottom surface of the avoidance groove 13 (i.e. the bottom wall of the water tank 10). The locating piece is equipped with the draw-in groove, the draw-in groove be equipped with towards the opening of below. When the clamping groove is clamped and connected with the limiting protrusion 33, the limiting protrusion 33 can be embedded in the clamping groove, so that the limiting protrusion 33 can limit the movement of the clamping groove relative to the limiting protrusion 33, and further limit the movement of the water tank 10 relative to the base shell 30.

In another possible implementation manner of the fitting part 14, fig. 8 is a schematic view of the bypass groove 13 in fig. 6, fig. 9 is a partial longitudinal sectional view of another section where the base shell 30 is fitted with the water tank 10 in fig. 2, and as shown in fig. 6, 8 and 9, the fitting part 14 may include two limiting ribs 142 disposed in the bypass groove 13, and both the limiting ribs 142 may be disposed perpendicular to the drawing direction of the water tank 10. The two limiting ribs 142 and a part of the groove wall of the avoiding groove 13 form a clamping groove for clamping and connecting with the limiting protrusion 33.

That is, the limiting rib 142 is connected to the bottom wall of the avoiding groove 13 and extends downward. The two limiting ribs 142 and the bottom wall of the avoiding groove 13 between the two limiting ribs 142 can form a clamping groove in a surrounding mode. In fig. 9, after the stopper projection 33 is engaged with the engaging groove, two stopper ribs 142 are arranged on the left and right sides of the stopper projection 33. In this manner, the stopper projection 33 restricts the movement of the water tank 10 relative to the base housing 30 in the left-right direction of the water tank 10, that is, the movement of the water tank 10 relative to the base housing 30 in the direction of the arrow X, by restricting the movement of the stopper rib 142 located on the left and right sides thereof. It should be noted that the groove bottom of the avoiding groove 13 between the two limiting protrusions 33 may abut against the upper end surface of the limiting protrusion 33, or may be provided with a certain gap from the upper end surface of the limiting protrusion 33.

Wherein, the cross section of spacing muscle 142 can be triangle-shaped to in stability, the structural strength that improves spacing muscle 142 and make spacing muscle 142 can cross spacing arch 33 steadily, and then make water tank 10 can move about in basic shell 30 steadily.

Specifically, reference may be made to the above description that the stopper projection 33 is a triangular projection. In fig. 8 and 9, an included angle between the left surface of the limiting rib 142 and the right side of the bottom wall of the water tank 10 is an acute angle, and an included angle between the right surface of the limiting rib 142 and the left side of the bottom wall of the water tank 10 is an acute angle. An acute angle between the left surface of the stopper rib 142 and the bottom wall of the water tank 10 is smaller than an acute angle between the right surface of the stopper rib 142 and the bottom wall of the water tank 10. So that the restricting rib 142 more easily gets over the right end of the restricting projection 33, more gently falls down from the highest point of the restricting projection 33, and more hardly gets over the left end of the restricting projection 33.

In yet another possible implementation manner of the engagement portion 14, the engagement portion 14 is a grid-shaped structure 141 disposed in the escape groove 13, and the grid-shaped structure 141 is engaged with the stopper protrusion 33.

Specifically, the possible implementation manners of the snap connection between the grid-shaped structure 141 and the limiting protrusion 33 are as follows:

in one possible implementation, for example, in fig. 8 and 9, on the left side of the avoidance space groove, a plurality of sets of grid structures are provided, and the plurality of sets of grid structures are arranged at intervals along the drawing direction of the water tank 10. The two adjacent sets of grid-shaped structures 141 and a part of the groove wall of the avoiding groove 13 between the two sets of grid-shaped structures 141 enclose a clamping groove. The locking groove is connected with the limiting protrusion 33 in a clamping manner.

In another possible implementation manner, for example, in fig. 8 and 9, on the right side of the avoidance groove 13, the lattice-shaped structure 141 and the avoidance groove 13 located on the right side of the lattice-shaped structure 141 enclose a clamping groove which is in clamping connection with the limiting protrusion 33. The locking groove is connected with the limiting bulge 33 in a clamping way.

When the second lattice-shaped structure 141 is used, the lattice-shaped structure 141 is necessarily positioned on the rightmost side of the avoidance groove 13. And the restriction of the right movement of the water tank 10 is greater than the former one. Fig. 8 and 9 use the two approaches described above to facilitate easier movement of the tank 10 from the second position, referred to below, to the first position, referred to below, and more stable resting in the second position for a user to add water to the tank 10.

The grid structure 141 may include a limiting rib 142 and a reinforcing rib 143. The limiting rib 142 can be referred to the description thereof of the previous example. That is, the two limiting ribs 142 and a part of the groove wall of the avoiding groove 13 between the two limiting ribs 142 form a clamping groove, and the clamping groove can be used for being clamped and connected with the limiting protrusion 33. The limiting rib 142 is further provided with a reinforcing rib 143. The upper end surface of the reinforcing rib 143 is connected with the bottom of the avoiding groove 13, the reinforcing rib 143 is perpendicular to the limiting rib 142, and the front end and the rear end of the reinforcing rib 143 are respectively connected with the front groove wall and the rear groove wall of the avoiding groove 13.

The number of the ribs 143 may be one or more, and it is understood that the larger the number of the ribs 143, the stronger the structure of the engaging portion 14. The number of the limiting ribs 142 can also be one or more, and understandably, the more the number of the limiting ribs 142 is, and when the limiting protrusions 33 are clamped with the limiting ribs 142, the stronger the limiting protrusions 33 are to the limiting ribs 142. The plurality of reinforcing ribs 143 and the plurality of stopper ribs 142 may form the above-mentioned lattice-shaped structure 141. Exemplarily, fig. 8 and 9 show that one net structure includes two limiting ribs 142 and two reinforcing ribs 143.

It should be noted that, as can be seen from fig. 5 to 9, the bottom wall of the water tank 10 is correspondingly provided with two fitting portions 14, and the two fitting portions 14 are spaced apart from each other along the drawing direction of the water tank 10. That is, the direction in which the line of the two fitting portions 14 is located coincides with the drawing direction of the water tank 10. The two fitting portions 14 have a certain distance therebetween. One of the fitting portions 14 is closer to the drawing end of the water tank 10 than the other fitting portion 14. The drawing end of the water tank 10 means an end for a user to apply force to draw the water tank 10 out of the base housing 30 or to push the water tank 10 into the base housing 30. Illustratively, the opening of the base housing 30 is disposed at the right side of the base housing 30 in the drawing, and the user pushes the water tank 10 into the base housing 30 from right to left, so the right end of the water tank 10 in the drawing is a drawing end of the water tank 10. So that in fig. 6 and 8, two fitting portions 14 are provided, one fitting portion 14 being disposed closer to the right end of the tank 10 than the other.

Fig. 9 shows a partial longitudinal sectional view of the base housing 30 at the location where the water tank 10 is engaged with the water tank 10 when the water tank 10 is located at the second position, and fig. 10 shows a partial longitudinal sectional view of the base housing 30 at the location where the water tank 10 is engaged with the water tank 10 when the water tank 10 is located at the first position, and as shown in fig. 9 and 10, the water tank 10 has a first position and a second position with respect to the base housing 30, and the water tank 10 is entirely located within the base housing 30 when the water tank 10 is located at the first position. When the water tank 10 is located at the second position, a part of the water tank 10 is located outside the base housing 30, and an upper end opening of the water tank 10 may be exposed, so that a user may add water into the water tank 10 through the exposed opening.

It should be noted that one or two limiting protrusions 33 may be provided. For example, when one of the limit protrusions 33 is provided, the engaging portion 14 near the drawing end of the water tank 10 is engaged with the limit protrusion 33 when the water tank 10 is located at the first position; when the water tank 10 is located at the second position, the engaging portion 14 away from the drawing end of the water tank 10 engages with the stopper protrusion 33.

As another example, when two stopper protrusions 33 are provided, as shown in fig. 9 and 10, when the water tank 10 is located at the first position, the engagement portion 14 of the drawing end of the water tank 10 is engaged with the stopper protrusions 33 near the opening of the base housing 30; when the water tank 10 is located at the second position, the engagement portion 14, which is away from the drawing end of the water tank 10, engages with the stopper projection 33, which is close to the opening of the base housing 30.

Of course, the number of the stopper projections 33 and the fitting portions 14 may also be more than two, the number of the stopper projections 33 may be the same as the number of the fitting portions 14, or the number of the stopper projections 33 may be one less than the number of the fitting portions 14. The arrangement when the number of the limiting protrusions 33 and the matching parts 14 exceeds two can be found by referring to the above, and will not be described herein again.

Alternatively, as shown in fig. 3 and 6, the outside of the water tank 10 is provided with a catching portion 15. The grip portion 15 may be provided with a space for the user to grip with his hand. For example, in fig. 7, the catching portion 15 may be a stepped groove provided at one side of the water tank 10. The groove has two groove bottoms of different depths in the vertical direction. The bottom of the tank near the end of the side wall of the water tank 10 is lower than the bottom of the tank far from the end of the side wall of the water tank 10, so that the side wall of the water tank 10, the bottom of the tank near the end of the side wall of the water tank 10, and the walls of the tanks between the two bottoms of the tanks can form a structure for a user to hold the hand in an upward bending manner.

Fig. 11 is a partially exploded view of the water tank 10 and the water slinging assembly 12 shown in fig. 2, and as shown in fig. 11, the water tank 10 may include a lower tank 101 and an upper cover 102 for facilitating installation of the water slinging assembly 12. The lower case 101 may be a hollow prism, and the upper end of the lower case 101 is open. The lower case 101 may include a bottom wall and a sidewall connected to the outer circumference of the bottom wall, the sidewall extending toward the upper end. The side wall of the lower box 101 may be provided with an air inlet. The upper cover 102 is detachably fitted over the opening of the lower case 101.

Wherein, the mode that gets rid of water subassembly 12 formation cascade can have following several:

in one possible implementation, fig. 12 is a front view of a water slinger assembly 12 of fig. 2, as shown in fig. 11 and 12, an axis of the water slinger assembly 12 is horizontal, and the water slinger assembly 12 rotates around the horizontal axis. The hydro slinger assembly 12 includes a disc body 121 and a plurality of outer ribs 122. A plurality of outer beads 122 are uniformly arranged on the surface of the disc main body 121. Each outer bead 122 is configured in a closed loop shape. And each of the outer ribs 122 defines a water storage space with the surface of the tray main body 121 to lift water in the water tank 10 and throw it out by the centrifugal force of the water slinging assembly 12.

Wherein, both sides of the disc main body 121 in the axial direction may be provided with an external rib 122 so as to increase the diffusion range of the water curtain in the axial direction of the disc main body 121. In addition, the above-mentioned "the outer beads 122 are each configured in a closed ring shape" means that the cross section of the outer bead 122 is a complete and closed ring shape; alternatively, the outer ribs 122 are part of a complete ring, and the outer ribs 122 can form a complete ring structure with other components. For example, FIG. 12 illustrates the sharing of an edge between adjacent ring structures. The outer beads 122 of fig. 12 are hexagonal, and a plurality of outer beads 122 form a honeycomb structure and are distributed over the surface of the disc main body 121.

As shown in fig. 11, the intake opening of the water tank 10 may be formed at the left side wall of the water tank 10, and the driving source may rotate the hydro slinger assembly 12 counterclockwise. The water storage space located below the water surface and located on the right side of the rotation axis of the water throwing assembly 12 stores a certain amount of water at a certain moment, and after the water throwing assembly 12 rotates anticlockwise, the water storage space can rotate to the upper side of the water surface and rotate to the left side of the rotation axis from the right side of the rotation axis. When the water storage space is located at the highest point and on the right side of the rotation axis, water carried in the water storage space is thrown out of the water storage space to form a water curtain.

It should be noted that the air inlet of the water tank 10 may be disposed on the front side wall or the rear side wall of the water tank 10, in addition to the left side wall of the water tank 10 as shown in fig. 11. The axis of rotation of the hydro slinger assembly 12 is parallel to the plane of the intake of the tank 10. Exemplarily, in fig. 11, the air inlet of the water tank 10 is disposed on the left side wall of the water tank 10, and the rotation axis of the water slinger assembly 12 is along the front-back direction of the water tank 10. When the air inlet of the water tank 10 is disposed on the front or rear side wall of the water tank 10, the rotation axis of the water throwing assembly 12 is along the left-right direction of the water tank 10.

With continued reference to fig. 12, each of the outer ribs 122 may have an inner rib 123 disposed therein, and each of the inner ribs 123 may also be configured in a closed loop shape. First water storage chamber 125 is injectd to the surface of every interior rib 123, the outer rib 122 that is located this interior rib 123 outside and the dish main part 121 that is located this interior rib 123 outside, and second water storage chamber 126 is injectd to the surface of every interior rib 123 and the dish main part 121 that is located the inboard of interior rib 123.

Specifically, the cross section of the inner rib 123 is a complete and closed ring shape; alternatively, the inner rib 123 is a part constituting a whole ring, and the inner rib 123 can form a complete ring structure with other components.

Referring to fig. 11 and 12, when the water storage space is rotated above the water level, a portion of water may be stored in the first water storage chamber 125 and a portion of water may be stored in the second water storage chamber 126. Along with the rising of the water storage space, the water in the water storage space is accumulated below the water storage space under the action of gravity. The inner convex rib 123 is arranged inside the outer convex rib 122, so that when the water storage space is located above the water surface, part of water in the water storage space is accumulated at the lower end of the first water storage chamber 125, and part of water is located at the lower end of the second water storage chamber 126, and the lower end of the first water storage chamber 125 and the lower end of the second water storage chamber 126 have different lowest positions, so that the water in the water storage space is arranged in a layered manner, so that the water in the water storage space has different paths after being thrown out, and the contact area of the water curtain and the air is favorably increased.

Further, the disc main body 121 may be provided with one; the disk main bodies 121 may also be provided in plurality, a plurality of the disk main bodies 121 may be arranged side by side in the axial direction of the disk main bodies 121, and a separation block 124 is provided between two adjacent disk main bodies 121. The spacer 124 can limit the interval between the adjacent two disk bodies 121. Fig. 3 illustrates an example in which one disc main body 121 is provided, and fig. 1 and 11 illustrate an example in which a plurality of disc main bodies 121 are provided.

The center of the tray body 121 may further have a center hole, and a rotation shaft penetrates the center hole of the tray body 121 and is rotatably coupled to a sidewall of the water tank 10. The driving source may rotate by driving the rotation shaft so that the disk main body 121 rotates with the rotation of the rotation shaft.

In another possible implementation of the hydro slinger assembly 12, the axis of the hydro slinger assembly 12 is vertical and the hydro slinger assembly 12 rotates about the vertical axis. The water throwing assembly 12 comprises a cylinder body with an opening at the lower end, and a space is arranged between the opening at the lower end of the cylinder body and the bottom wall of the water tank 10. The barrel includes roof and lateral wall, and the lateral wall of barrel is connected in the periphery of the roof of barrel and is extended downwards. The upper end lateral wall of the cylinder body is provided with a water throwing hole. The rotating shaft penetrates through the barrel body along the vertical direction and is fixed with the bottom wall of the barrel body. The driving source drives the rotating shaft to drive the barrel to rotate. Along with the rotation of the cylinder, the water in the water tank 10 enters the cylinder from the lower end opening of the cylinder and gradually ascends. When the water climbs to the position of the water throwing hole, the water in the cylinder body is thrown out from the water throwing hole to form a water curtain.

The driving source is used for driving the rotating shaft to rotate. The driving source may be provided at the base housing 30 and the driving source may also be provided at the water tank 10. When the driving source is provided on the base housing 30, a disk driving member may be connected to one end of the rotation shaft, and the disk driving member may be rotatably provided to the water tank 10. Gear teeth are arranged on the periphery of the disc-shaped transmission piece. The base housing 30 located at the outer side of the water tank 10 may be provided with an engaging member engaged with the gear teeth of the disk drive and a driving source. That is, the driving source drives the engaging member to move, so that the disc-shaped transmission member rotates, and further the rotating shaft rotates, thereby achieving the purpose of rotating the water slinging assembly 12. The meshing component can be a gear or a gear train, and can also be a strip-shaped toothed belt provided with gear teeth. The drive source may rotate the gear member or drive the toothed belt in a linear motion. The driving source can be powered by an external power supply or a storage battery.

In order to realize that the air is guided by the fan to sequentially pass through the air inlet of the base housing 30 and the air inlet of the water tank 10 and enter the water tank 10, the air inlet of the water tank 10 may be opposite to the air inlet of the base housing 30. That is, the inlet opening of the water tank 10 is formed at a side wall of the water tank 10 facing the inlet opening of the base housing 30. The air introduced into the water tank 10 is mixed with a water curtain formed by the water throwing assembly 12 to purify and humidify the air. In order to realize that the purified and humidified air sequentially flows out of the base housing 30 through the air outlet of the water tank 10 and the air outlet of the base housing 30, the air outlet of the water tank 10 may be opposite to the air outlet of the base housing 30. That is, the outlet port of the water tank 10 is provided at a side wall of the water tank 10 facing the outlet port of the base housing 30. Exemplarily, in fig. 3 and 11, the air inlet of the water tank 10 is disposed on the left side wall of the water tank 10, and the air outlet of the water tank 10 is disposed on the top wall of the water tank 10; the air inlet of the base housing 30 is disposed on the left side wall of the base housing 30, and the air outlet of the base housing 30 is disposed on the top wall of the base housing 30.

In order to prevent the air introduced into the base housing 30 from being directly discharged from the outlet port of the base housing 30 without passing through the water tank 10, a wind blocking plate may be disposed between the inlet port of the base housing 30 and the outlet port of the base housing 30 to block the inlet port of the base housing 30 from the outlet port of the base housing 30. In order to prevent air flowing out of the air outlet of the water tank 10 from re-entering the air inlet of the water tank 10, an air baffle may be disposed between the air inlet of the water tank 10 and the air outlet of the water tank 10, so as to separate the air inlet of the water tank 10 from the air outlet of the water tank 10. In summary, the air inlet of the base housing 30 and the air inlet of the water tank 10 may be disposed at one side of the wind shield. The air outlet of the base housing 30 and the air outlet of the water tank 10 are disposed at the other side of the wind shield.
