Detailed Description

The existing air purifier comprises a base shell provided with a fan, a water tank positioned below the base shell and a humidifying component positioned in the water tank. The water wash assembly is capable of creating a water curtain with water in the tank. The water curtain is mixed with the air to purify and humidify the air. The outside air enters the water tank through the air inlet of the water tank under the guidance of the fan. After being mixed with the water curtain in the water tank, the mixture flows out of the base shell through the air outlet of the water tank and the air outlet of the base shell. However, since the mounting port of the water tank is disposed below the base shell, the user needs to vertically move the water tank when taking and placing the water tank, which is not only laborious, but also very inconvenient. Meanwhile, when the air purifier is integrated in the cabinet air conditioner, enough space needs to be reserved in the vertical direction for taking and placing the water tank, and a support structure with enough strength needs to be arranged for the air purifier in the shell of the cabinet air conditioner correspondingly.

In view of this, the air purifier provided by the embodiment of the present invention arranges the water tank inside the base housing in a slidable manner, and arranges the water tank mounting port on the side wall of the base housing, so that a user can take out the water tank along a horizontal direction, which is not only labor-saving, but also convenient to operate. When the air purifier is integrated into the vertical air conditioner, the installation height of the air purifier can be correspondingly reduced, and a high-strength supporting structure is not required to be configured to support the air purifier.

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 indicated by the arrow Y is the front direction, and the other direction is the back direction; the direction indicated by the arrow Z is up, and the other direction is down.

Fig. 1 is a perspective view of an air cleaner according to an embodiment of the present invention, and fig. 2 is a partially exploded view of fig. 1. As shown in fig. 1 and 2, the 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 sump 10 detachably fitted in the base housing 30, and a hydro-extracting assembly 12 rotatably disposed in the sump 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. 2, an opening is formed in a right side wall of the base housing 30, and the water tank 10 can be drawn out through the right side opening of the base housing 30. Thus, the water tank 10 can be prevented from being taken out from below, and the user can conveniently take out the water tank 10.

The above-mentioned "the water container 10 is detachably fitted in the base housing 30" means that the base housing 30 and the water container 10 are two separate members. The two can be connected in a detachable connection mode such as a fastener, a clamping connection mode, a mortise-tenon joint mode and the like. 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 moves relative to the base housing 30. And by pulling the water tank 10, the water tank 10 comes out of the opening of the base housing 30.

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 22 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. Thus, the purification and humidification of the air is completed.

The structure of the air cleaner will be described in order from the inside to the outside, taking as an example the position where the opening is provided in fig. 2, i.e., the position where the opening is provided in the right side wall of the base housing 30.

The hydro slinger assembly 12 is first described.

Fig. 3 is a partially exploded view of the water tank 10 and the water slinger 12 of fig. 1, and fig. 4 is a front view of the water slinger 12 of fig. 1. Referring to fig. 3 and 4, the water slinger 12 can rotate around its own axis in the water tank 10, and the rotation axis of the water slinger 12 is horizontal. 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. 4 illustrates that two adjacent outer ribs 122 share an edge, thereby forming a grid-like structure. The outer beads 122 of fig. 4 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.

Referring to fig. 3 and 4, an air inlet of the water tank 10 may be provided at a left side wall of the water tank 10, and the driving source 22 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. 4. The axis of rotation of the hydro slinger assembly 12 is parallel to the plane of the intake of the tank 10. Illustratively, in fig. 2, the air inlet of the water tank 10 is disposed at the left side wall of the water tank 10, and the rotation axis of the hydro-extracting cage 12 is along the front-rear 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. 4, each outer rib 122 may have an inner rib 123 disposed therein, and each inner rib 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. 3 and 4, 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, part of the water is located at the lower end of the second water storage chamber 126, the lower end of the first water storage chamber 125 and the lower end of the second water storage chamber 126 are at different lowest positions, and thus, 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. 2 illustrates an example in which one disc main body 121 is provided, and fig. 1 and 3 illustrate an example in which a plurality of disc main bodies 121 are provided.

The center of the disc body 121 may further be provided with a center hole, and a rotating shaft 11 is inserted through the center hole of the disc body 121 and rotatably disposed on the sidewall of the water tank 10. The drive source 22 can rotate by driving the rotation shaft 11 so that the disk main body 121 rotates with the rotation of the rotation shaft 11.

Wherein, realize that dish main part 121 follows pivot 11 and rotates, can adopt following several kinds of modes:

in one possible implementation, the shaft 11 is an interference fit with the central bore. In this way, the mutual rotation between the rotating shaft 11 and the center hole is avoided, and the position of the disk main body 121 in the axial direction of the rotating shaft 11 is determined.

In another possible implementation, the cross-section of the shaft 11 is designed to be non-circular, and the shape of the central hole is made to conform to the cross-sectional shape of the shaft 11. In this manner, the disk main body 121 can rotate with the rotation of the rotation shaft 11.

Illustratively, referring to fig. 4, the cross-section of the rotating shaft 11 may be a regular hexagon, and the central hole is a hexagon opposite to the rotating shaft 11. A reinforcing ring 127 coaxial with the central hole can be arranged in the central hole, the section of the reinforcing ring 127 is hexagonal, and two sides of each edge on the inner side of the reinforcing ring 127 can be respectively provided with a limiting rib 128. During installation, the rotating shaft 11 penetrates into the reinforcing ring 127 along the axis of the reinforcing ring 127, and the edge of the rotating shaft 11 corresponds to the edge of the reinforcing ring 127. Thus, the edge of the rotation shaft 11 is thus held between two adjacent limit ribs 128 by the two limit ribs 128, so that the edge of the rotation shaft 11 is restricted between the two adjacent limit ribs 128 to restrict the relative movement between the rotation shaft 11 and the disc main body 121. Of course, the cross section of the rotating shaft 11 may also be other non-circular shapes, which is only illustrated here and is not limited in any way.

Fig. 5 is an exploded view of the joint of the rotating shaft 11 and the disc drive 13 of fig. 2 (the disc main body 121 is provided as an example in fig. 5), and referring to fig. 5, optionally, a water storage groove 111 is provided on the surface of the rotating shaft 11. When the reservoir 111 is under water, it can hold some water. When the water storage tank 111 rotates to the upper right side along with the rotating shaft 11, the water in the water storage tank 111 can be discharged outwards. Thus, the resistance to the rotation of the rotating shaft 11 in the water is reduced. The number of the water storage tanks 111 is two, and the two water storage tanks 111 have opposite opening directions. That is, the openings of the water storage tank 111 are disposed at two opposite surfaces of the rotation shaft 11.

The water tank 10 will be described below.

Referring to fig. 3, to facilitate installation of the hydro slinger assembly 12, the tank 10 may include a lower housing 101 and an upper cover 102. 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.

It should be noted that, since the below-mentioned disk drive 13 is provided in the water tank 10 and the below-mentioned drive source 22 and drive source 22 are provided in the base housing 30, the air inlet of the water tank 10 needs to be provided at a position opposite to the opening direction of the base housing 30. Illustratively, in fig. 1-3, the right sidewall of the base housing 30 is open to allow the water tank 10 to be withdrawn to the right. The air inlet is provided at the left side wall of the water tank 10.

When the air inlet of the base housing 30 is opposite to the air inlet of the water tank 10, that is, the projection of the air inlet of the base housing 30 on the surface where the air inlet of the water tank 10 is located has an overlapping portion with the air inlet of the water tank 10, so that the flow path of air can be reduced.

Optionally, the top wall of the water tank 10 is provided with an air outlet. When the water in the water storage space rotates to the highest point of the motion track, the water in the water storage space starts to fly outwards and makes a downward parabolic motion under the action of gravity. Air entering from the side wall of the water tank 10 flows out from the upper end of the water tank 10 and contacts the water droplets moving downward in the course of the upward flow of the air. Thus achieving the purposes of humidifying air and purifying air.

For example, fig. 1-3 illustrate the top wall of the base housing 30 having an air outlet, and the top wall of the water tank 10 having an air outlet. Of course, when the outlet of the base housing 30 is disposed on the top wall of the base housing 30, the outlet of the water tank 10 may be disposed on the side wall of the water tank 10. When the air outlet of the base housing 30 is opposite to the air outlet of the water tank 10, that is, the projection of the air outlet of the base housing 30 on the plane where the air outlet of the water tank 10 is located has a superposition portion with the air outlet of the water tank 10, so that the flow path of the air can be reduced.

Fig. 7 is a sectional view of the air cleaner of fig. 1, and as shown in fig. 7, the highest point of the tray body 121 may be optionally higher than the highest point of the intake opening of the water tank 10. So that at least part of the water storage space is positioned at the upper end of the air inlet in the rotating process of the rotating shaft 11, and the contact chance of water drops thrown out of the water storage space and air entering from the air inlet is increased.

Alternatively, a portion of the tray body 121 may pass through the outlet port of the water tank 10. Just can be so that the water storage space is located the upper end of air outlet, just can increase the contact opportunity of the water droplet that is thrown away in the water storage space and the air that flows from the air outlet.

Alternatively, a water baffle 15 may be provided below the air inlet, the water baffle 15 being inclined with respect to the side wall of the water tank 10. In fig. 7, a first end of the water guard 15 is connected to the intake port of the water tank 10, and a second end of the water guard 15 extends upward and is inclined toward the left side of the water tank 10. The water baffle 15 can not only block water drops passing through the air inlet back into the water tank 10, but also guide air downwards into the water tank 10.

Optionally, the upper end of the tank 10 is provided with a deflector 16 extending towards the inside of the tank 10, the deflector 16 being inclined with respect to the top wall of the tank 10, and the deflector 16 being used to direct air towards the hydro-extracting cage 12. In fig. 7, a first end of the air deflector 16 is connected to the air outlet of the water tank 10, and a second end of the air deflector 16 extends downward and inclines toward the water slinger 12. The air deflector 16 can guide the air below the air deflector toward the water slinger 12, so that the air is firstly contacted with the water drops thrown by the water slinger 12 below the air deflector, and the contact probability of the air and the water drops is increased. In addition, water drops thrown out from the water storage space at the upper end of the air outlet can flow into the water tank 10 along the air guide plate 16, so that the water loss is avoided.

Alternatively, as shown in fig. 3, a preliminary filtering member 17 may be provided at the air inlet of the water tank 10 to filter impurities having large particles. In order to replace the primary filter member 17 conveniently, the sidewall of the water tank 10 may be provided with a first slide rail 18, and the primary filter member 17 may be slidably mounted on the first slide rail 18. Specifically, the two sides of the air inlet can be respectively provided with two parallel first sliding rails 18, the lower end of each first sliding rail 18 can be provided with a bottom plate, the upper end of each first sliding rail 18 is provided with an opening, and the primary filter component 17 can penetrate into the first sliding rail 18 from the opening at the upper end of the first sliding rail 18 and continuously slide in the first sliding rail 18 until the primary filter component 17 abuts against the bottom plate.

The base shell 30 is described below.

As shown in fig. 1 and 2, the base housing 30 may alternatively include a lower housing 301 provided with an air inlet and an upper housing 302 provided with an air outlet. 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.

Fig. 8 is a partial sectional view of the air cleaner of fig. 1, and referring to fig. 2 and 8, alternatively, the base housing 30 is provided with a second recess 106, the second recess 106 is provided with an opening toward the outside of the base housing 30, the outside of the water tank 10 is provided with a second slide rail 35, and the second slide rail 35 is fittingly coupled with the second recess 106. The second slide rail 35 is provided in the drawing direction of the tank 10 so that the tank 10 slides within the base housing 30 along a predetermined trajectory, and the distance between the front wall of the tank 10 and the front wall of the base housing 30 and the distance between the rear wall of the tank 10 and the rear wall of the base housing 30 are determined.

Fig. 9 is an enlarged view of fig. 7 at a, and referring to fig. 7 and 9, alternatively, the base housing 30 is provided at an outer side thereof with a stopper protrusion 37, and the water tank 10 is provided with a stopper groove having an opening toward the outer side of the water tank 10, the stopper groove being capable of receiving the stopper protrusion 37. The stopper protrusion 37 is engaged with the stopper groove to prevent the water tank 10 from moving relative to the base housing 30 after being mounted to the base housing 30.

The cross section of the limiting protrusion 37 may be trapezoidal, and an included angle between a side edge and a bottom edge of the trapezoid is smaller than 90 degrees. The shape of the limiting groove is matched with the limiting bulge 37, and the shape of the limiting groove is also trapezoidal. In fig. 7, when the water tank 10 is installed, one end of the water tank 10 may be placed at the opening of the base housing 30 and the water tank 10 may be pushed leftward such that the water tank 10 enters the base housing 30. The stopper groove may pass over the stopper protrusion 37 during the leftward movement of the water tank 10. After the water tank 10 stops moving leftward, the limiting groove is covered above the limiting protrusion 37 and limits the movement of the limiting protrusion 37 relative to the limiting groove, thereby limiting the movement of the water tank 10 relative to the base housing 30.

Referring to fig. 7, the outside of the water tank 10 is optionally provided with a catching portion 109. The grasping portion 109 may be provided with a space for grasping by a hand of a worker user. When the base housing 30 is provided with the above-mentioned stopper projection 37, the grasping portion 109 may be provided with a space for the user to hold with his hand. For example, in fig. 7, the catching portion 109 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.

The flow of air between the base housing 30 and the water tank 10 will be described.

With continued reference to fig. 7, an airflow path is formed between the inside of the base housing 30 and the outside of the water tank 10. A wind shield 31 may be disposed between the base housing 30 and the water tank 10, and the wind shield 31 may divide the air flow channel into an air inlet channel 311 and an air outlet channel 312.

Specifically, the water tank 10 is located inside the base housing 30, and the air inlet of the water tank 10 and the air outlet of the water tank 10 are located inside the base housing 30. There is a certain space between the outside of the water tank 10 and the inside of the base housing 30. The space forms an air flow passage for air to flow between the base housing 30 and the water tank 10. It should be noted that, in order to reduce the loss of energy caused by the air flowing in the airflow channel, the volume of the airflow channel may be reduced. For example, in fig. 7, 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, so that the bottom wall of the water tank 10 can be closely attached to the bottom wall of the base housing 30 to prevent air from flowing below the water tank 10. The front/rear side walls of the water chamber 10 and the front/rear side walls of the base housing 30 may also be closely attached to prevent air from flowing in the front/rear direction of the water chamber 10.

In fig. 7, in order to increase the intake air amount of the base housing 30, an intake opening is also formed in the top wall of the base housing 30. In order to make the air inlet disposed on the top wall of the base housing 30 and the air inlet disposed on the side wall of the base housing 30 converge and flow into the water tank 10 from the air inlet, as shown in fig. 7, a distance may be provided between the side wall of the water tank 10 where the air inlet is disposed and the side wall of the base housing 30 where the air inlet is disposed, and the air inlet disposed on the top wall of the base housing 30 is opposite to the distance.

Of course, when the air inlet is not formed on the top wall of the base housing 30, in fig. 7, the side wall of the base housing 30 on which the air inlet is formed and the side wall of the water tank 10 on which the air inlet is formed may be opposite and closely attached. The above-mentioned water deflector 15 for blocking the outflow of the water curtain may be provided at the outside 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 shield 31 is disposed between the inlet port of the base housing 30 and the outlet port of the base housing 30 so as to separate 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 31 is 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, one side of the wind deflector 31 may form the air inlet channel 311, and the other side of the wind deflector 31 may form the air outlet channel 312. The air inlet of the base housing 30 and the air inlet of the water tank 10 can be disposed at one side of the wind shield 31. 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 31. Fig. 7 illustrates a wind deflector 31 provided between the top wall of the water tank 10 and the top wall of the base housing 30. Of course, the wind shielding plate 31 may be disposed between the side wall of the water tank 10 and the side wall of the base housing 30 when the air inlet is not formed in the top wall of the base housing 30.

Illustratively, as shown in fig. 7, the inner wall (including the left side wall, the front side wall, and the rear side wall) of the base housing 30 between the air inlet of the base housing 30 and the air inlet of the water tank 10, the top wall of the base housing 30 on the left side of the air baffle 31, the side wall of the water tank 10 provided with the air inlet, and the top wall of the water tank 10 on the left side of the air baffle 31 enclose an air inlet channel 311. The top wall of the water tank 10 located on the right side of the wind screen 31, the right side wall of the water tank 10, the top wall of the base shell 30 located on the right side of the wind screen 31, and the wind screen 31 enclose an air outlet channel 312.

While the arrows in fig. 7 indicate the flow direction of the air, with continued reference to fig. 7, the air outside the base housing 30 enters the air inlet passage 311 from the air inlet of the base housing 30 under the guidance of the blower, and enters the water tank 10 from the air inlet of the water tank 10 through the air inlet passage 311. The air introduced into the water tank 10 is contacted with the water lifted by the hydro-extracting cage 12 to purify and humidify the air. The purified and humidified air flows out to the outside of the base housing 30 through the air outlet of the water tank 10, the air outlet channel 312, and the air outlet of the base housing 30.

Alternatively, the fan may be disposed at the air inlet end of the base housing 30, and the fan may also be disposed at the air outlet end of the base housing 30. Optionally, a wind deflector 31 is attached to the inner wall of the base shell 30. The outer wall of the water tank 10 is connected with a wind shielding protrusion 105, and the wind shielding protrusion 105 is disposed on one side of the wind shielding plate 31 and extends toward the outer side of the water tank 10. The wind-shielding protrusion 105 faces away from the end surface of the water tank 10, further from the water tank 10 (or closer to the base housing 30) than the wind-shielding plate 31 faces away from the end surface of the base housing 30. Illustratively, in fig. 7, the wind guard 31 is connected to the top wall of the base housing 30 and extends downward, and the wind guard protrusion 105 is connected to the top wall of the water tank 10 and extends upward. The wind shielding protrusion 105 is provided on the right side of the wind shield 31. And the highest point of the wind-shielding protrusion 105 is higher than the lowest point of the wind-shielding plate 31. That is, the wind shield 31 and the wind shielding protrusion 105 shield wind in a stacked manner, so that the base housing 30 and the water tank 10 are not fastened, the water tank 10 is separated from the base housing 30, and the maintenance personnel can conveniently disassemble and assemble the water tank.

Since one side wall of the base housing 30 is provided with an opening, the water tank 10 located inside the base housing 30 is drawn out through the opening. In order to prevent the air flowing out of the outlet of the water chamber 10 from flowing out of the opening, a first sealing plate 107 is provided at the opening to close a gap between the water chamber 10 and the base housing 30 at the opening. For example, in fig. 7, a first sealing plate 107 extending toward the base housing 30 may be connected to an upper end of the water tank 10. A second sealing plate 36 extending toward the water tank 10 may be connected to the opening of the base housing 30. The first sealing plate 107 is disposed at one side of the second sealing plate 36, and the highest point of the first sealing plate 107 is higher than the lowest point of the second sealing plate 36. In this manner, the base housing 30 and the water tank 10 are sealed at the opening of the base housing 30 in such a manner that the first sealing plate 107 and the second sealing plate 36 overlap.

In fig. 7, the wind shielding protrusion 105 and the first sealing plate 107 connected to the water tank 10 are respectively disposed on the right side of the wind shielding plate 31 and the second sealing plate 36, so that the wind shielding protrusion 105 is separated from the wind shielding plate 31 and the first sealing plate 107 is separated from the second sealing plate 36 when the water tank 10 is drawn out to the right.

The arrangement of the driving part for driving the rotation of the rotation shaft 11 on the base housing 30 and the water tank 10 will be described.

Since the base shell 30 is disposed outside the water tank 10, in order to prevent the distance between the inside of the base shell 30 and the outside of the water tank 10 from being too large, and further prevent the air entering the base shell 30 from staying between the base shell 30 and the water tank 10 for too long, both axial ends of the rotating shaft 11 are disposed inside the water tank 10, one end of the rotating shaft 11 may be connected with a disc-shaped transmission member 13, and the disc-shaped transmission member 13 may be rotatably disposed inside the water tank 10. The disc drive 13 is provided with gear teeth on its periphery. The upper end of the base housing 30 located at the outside of the water tank 10 is provided with the engaging member 20 and the driving source 22. The upper end of the water tank 10 may be provided with a first coupling hole 104, and a portion of the disk-shaped transmission member 13 may be engaged with the engaging member 20 through the first coupling hole 104.

Wherein, the driving source 22 drives the engaging member 20 to move, so that the disc-shaped transmission member 13 rotates, and further the rotating shaft 11 rotates, thereby achieving the purpose of rotating the water slinging assembly 12. The engaging member 20 may be a gear or a gear train, or a strip-shaped toothed belt provided with gear teeth. The drive source 22 may rotate the gear element 20 or drive the belt in a linear motion. The driving source 22 may be powered by an external power source or a battery.

As shown in fig. 3 and 5, the inside of the water tank 10 is provided with a mounting groove 103, and the disc driving member 13 is rotatable with respect to the mounting groove 103. Alternatively, the side wall of the water tank 10 is provided with a recess provided with an opening toward the outside of the water tank 10, a part of the recess serves as the mounting groove 103, and the groove wall of the mounting groove 103 is used to support the disc-shaped transmission member 13. Illustratively, the recess is concave. The two ends of the recessed portion are higher than the middle portion of the recessed portion, and the middle portion of the recessed portion may form the above-mentioned mounting groove 103.

In order to avoid wear between the disc drive 13 and the mounting slot 103, an end cap 14 may be provided between the mounting slot 103 and the disc drive 13. The end cap 14 is detachably disposed between the mounting groove 103 and the disc drive 13. And, the end cover 14 is rotatably disposed in the mounting groove 103, and the end cover 14 can also rotate following the rotation of the disc transmission member 13. It will be appreciated that after the end cap 14 has worn, the end cap 14 may be removed from the disc drive 13 and replaced with a new end cap 14. Compared with the replacement of the disc-shaped transmission piece 13, the replacement of the end cover 14 has the advantages of low maintenance cost and convenience in replacement.

The connection between the end cap 14 and the disc drive 13 includes, but is not limited to, the end cap 14 being screwed to the disc drive 13, the end cap 14 being fastened to the disc drive 13, and the end cap 14 being fastened to the disc drive 13.

Alternatively, with reference to fig. 5, positioning blocks may be provided between the disc drive 13 and the hydro slinger assembly 12, so that the position of the disc drive 13 and the hydro slinger assembly 12 in the axial direction can be determined. So as to facilitate rapid transfer.

Optionally, there are two each of the disk drives 13 and the mounting slot 103. The two disc-shaped transmission members 13 can be respectively connected with two ends of the rotating shaft 11, and the two disc-shaped transmission members 13 respectively abut against the bottoms of the two mounting grooves 103. So as to restrict the axial direction movement of the rotating shaft 11. In addition, the rotating shaft 11 is screwed to the disc drive 13 to facilitate the removal of the rotating shaft 11 from the disc drive 13.
