Description

Technical Field

[0001] The present invention belongs to the technical field of purification appliances, and particularly relates to a base body and an air purification device. Background Art

[0002] With the increasingly deteriorating environment, the problem of air pollution has attracted more and more extensive attention from people. Therefore, various air purifiers have emerged as the times require. An air purifier refers to a product that can adsorb, decompose or transform various air pollutants and can effectively improve the air cleanliness.

[0003] At present, the air purifiers used in families all adopt the method of dry multi-layer filtration and adsorption (such as electrostatic adsorption, activated carbon adsorption, HEPA filtration, etc.) to purify the air. When such air purifiers are working, pollutants will directly accumulate on the filter screen of the filtering device. If accumulated for a long time, the pores on the filter screen will be blocked, affecting the air filtration effect, and the dust accumulated on the filter screen will become a breeding ground for bacteria and form secondary pollution. Therefore, water-washing air purification products have emerged as the times require.

[0004] The existing water-washing air purification device includes a water tank, a water curtain assembly and a power assembly. The power assembly is used to drive the water curtain assembly to rotate in the water tank so as to form a water curtain. An air inlet is provided on the side wall of the water tank, and the dust-containing gas from the outside enters the water tank through the air inlet and comes into full contact with the water curtain to be purified. Among them, the power assembly includes a motor. When the motor works, it generates vibration, resulting in the generation of relatively large noise and affecting the use of users. Summary of the Invention

[0005] In order to solve the above problems in the prior art, that is, to solve the problem that when the motor of the existing water-washing air purification device works, it generates vibration, resulting in the generation of relatively large noise and affecting the use of users, the present invention provides a base body and an air purification device. Among them, a base body is used for installing a motor. The motor includes a motor main body and a motor shaft. The base body includes: a base, the motor main body is suspended and installed on the base, and the motor shaft passes through the base; a base shell, sleeved outside the base, and a preset distance is provided between at least part of the base and the base shell; a fixing member, with two ends respectively connected to the base and the base shell.

[0006] In a preferred technical solution of the above base body, a vibration damping member is provided between the motor main body and the base.

[0007] In a preferred technical solution of the above base body, a ring-shaped vibration damping protrusion is connected to the base, the vibration damping protrusion extends towards the motor main body, the vibration damping member is sleeved on one end of the motor main body close to the base, and is embedded in the vibration damping protrusion.

[0008] In a preferred technical solution of the above-mentioned base body, the base includes a bottom wall and a side wall. The main body of the motor is suspended from the bottom wall of the base. The side wall of the base is connected to at least a part of the outer periphery of the bottom wall of the base and extends in a direction away from the main body of the motor.

[0009] In a preferred technical solution of the above-mentioned base body, at least a part of the upper end of the base is connected to the upper end of the base shell, and the base and the base shell are integrally provided.

[0010] In a preferred technical solution of the above-mentioned base body, circumferential ribs are connected to the base. The circumferential ribs are sleeved outside the main body of the motor and are arranged along the circumference of the base.

[0011] In a preferred technical solution of the above-mentioned base body, radial ribs are connected to the base. The radial ribs are arranged along the radius of the base and intersect the circumferential ribs.

[0012] In a preferred technical solution of the above-mentioned base body, the radial ribs are connected to the bottom wall of the base and extend in the direction of the main body of the motor. At least a part of the fixing member is bent relative to the radial ribs.

[0013] In a preferred technical solution of the above-mentioned base body, a damping groove is provided at one end of the fixing member close to the bottom wall of the base. The damping groove has an opening facing the main body of the motor.

[0014] An air purification device includes a water tank and a motor, and further includes the base body as described in any one of the above. The base body includes a base and a base shell. The main body of the motor is suspended from the base, and at least a part of the water tank is embedded in the base.

[0015] Those skilled in the art can understand that for the base body and the air purification device of the present invention, by providing the base and the base body, and suspending and installing the motor on the base, the contact area between the motor and the base is reduced, the vibration between the motor and the base is reduced, and thus the noise generated between the base and the fan is reduced. In addition, the base shell is sleeved outside the base, and the base and the base shell are connected by fixing members, reducing the vibration influence of the motor on the base shell. The air purification device is connected to other objects through the base shell, so the vibration between the base shell and other objects is reduced, which is beneficial to reducing the noise generated by the air purification device.

[0032] Figure 1 Stereoscopic schematic diagram showing an air purification device, referring to Figure 1As shown, the air purification device of the present invention may include an air inlet section 3, a water washing section 1, and an air outlet section 4 according to the air flow direction. The water washing section 1 includes a water tank 11 and a water washing assembly disposed in the water tank 11. The water washing assembly forms a water curtain with the water in the water tank 11 under the power provided by the power section 2. After the dust-containing gas enters the water washing section 1 from the air inlet section 3, it can pass through the water curtain formed by the water washing assembly, so that the dust, bacteria, viruses, etc. in the dust-containing gas are dissolved in water or removed by the water molecules and negative ions in the water curtain, thereby completing the water washing and purification of the dust-containing gas. The clean gas washed and purified by the water washing section 1 is discharged from the air outlet section 4 to improve the air quality of the surrounding area.

[0033] In Figure 1 the air purification device is further provided with a base body 5 for carrying the water tank 11, and the air inlet section 3 and the power section 2 can be arranged relying on the base body 5 to achieve modular and integrated settings. In other words, the air inlet section 3 can be formed as an integral part with the base body 5 by molding. For example, the side wall or the bottom wall of the integral part serves as the air inlet section 3, and the bottom wall of the integral part is used to install the power section 2 and support the water tank 11.

[0034] The water tank 11 has an air inlet communicating with the air inlet section 3 and an air outlet communicating with the air outlet section 4. Exemplarily, the air outlet section 4 may include an air outlet hood 41. The air outlet hood 41 can cover the air outlet of the water tank 11, and the purified gas enters the air outlet hood 41 from the air outlet of the water tank 11, so that the purified gas can be guided in any required direction through the air outlet hood 41. For example, Figure 1 shows that the purified air discharged from the air outlet of the water tank 11 is guided to the Figure 1 left side, right side, and rear side in

[0035] The following will separately describe each part of the air purification device in detail.

[0036] First, the water tank 11 will be described below.

[0037] Figure 2 shows a three-dimensional schematic diagram of a water washing section; as Figure 2 shown, the water tank 11 can be made of a transparent material, for example, it can be made by molding transparent plastic. The water tank 11 can hold the air washing liquid for cleaning the air. The washing liquid can be clean water, but is not limited to clean water. For example, it can also be water mixed with a disinfectant. For the sake of simplicity of description, water will be used as an example in the following, but this should not be regarded as a specific limitation of the protection scope.

[0038] As Figure 2 shown, the upper part of the water tank 11 is for gas flow, and the lower part of the water tank 11 is for holding water. The air inlet 111 of the water tank 11 can be arranged on the upper side wall of the water tank 11, and a primary filter assembly can be provided outside the air inlet 111 as described below.

[0039] Continue as Figure 2 shown, the top end of the water tank 11 can be open to serve as an air outlet, and the gas entering the interior of the water tank 11 can flow out from the open end at the top of the water tank 11. An upper water retaining structure 15 can be provided at the air outlet as described below.

[0040] It should be noted that the positions of the air inlet 111 and the air outlet can also be set differently from Figure 2 that shown. For example, the positions of the air inlet 111 and the air outlet can be swapped, or in some examples, the air inlet 111 and the air outlet can also be provided on the opposite side walls of the water tank 11. The following describes the air purification device of this solution with the air inlet 111 provided on the side wall of the water tank as an example. For other setting methods of the air outlet, those skilled in the art can refer to the following to obtain, and will not be elaborated here.

[0041] Continue to refer to Figure 2 , the number of the air inlets 111 can be multiple, but only one can also be provided, and the shape and size of each air inlet 111 can be set according to actual needs. As Figure 2 shown, when there are multiple air inlets 111, these air inlets 111 can be evenly distributed along the circumferential direction of the side wall of the water tank 11 to evenly divide the gas, so that the gas entering the water tank 11 is evenly distributed.

[0042] It is worth noting that when the air inlet is provided 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 where the water curtain formed by the water washing assembly is located, so that the dust-containing air entering the water tank 11 from the air inlet can only flow out from the air outlet of the water tank 11 after being washed by the water curtain. It should be noted that since water is affected by gravity, the plane where the water curtain is located here is a general reference. In principle, the upper end surface of the air inlet should be below the intersection line of the water curtain and the side wall.

[0043] As can be seen from the above, the lower part of the water tank 11 is used to hold water, so scale lines can be provided on the lower side wall of the water tank to facilitate users to observe and control the liquid level of the water tank 11. It is easy to understand that the water tank 11 can also be made of a transparent material only in the part where the scale lines are provided, and the rest is made of a non-transparent material, so that users can observe the water level in the water tank 11 through the scale lines of the transparent part. Refer to Figure 2 shown, the scale lines can include a minimum liquid level line, which can be shown as "0"; or can also include a maximum liquid level line, which can be shown as "max". It can be understood that the scale line marked with "max" is located below the air inlet.

[0044] To understand the invention content of this solution more quickly, the water washing component will be described below. Among them, the structure of the water washing component includes, but is not limited to, the following possible implementation methods:

[0045] In one possible implementation method, Figure 4 A schematic diagram of a water washing component for forming a water curtain is shown, as Figure 4 shown, the water washing component can lift the water stored in the water tank 11 upward and spray the water towards the inner wall direction of the water tank 11. Specifically, the water washing component can include a hollow cylinder 12, and the lower end of the cylinder 12 is communicated with the lower end of the water tank 11. Exemplarily, the lower end of the cylinder 12 is provided with an opening. There is a gap between the lower end opening of the cylinder 12 and the bottom wall of the water tank 11, so that the water in the water tank 11 can enter the inside of the cylinder 12 from this gap. The power part 2 can make the cylinder 12 rotate around its own axis, so that the water entering the cylinder 12 gradually moves upward along the inner wall of the cylinder 12 under the action of the rotational force. A plurality of water throwing holes 121 are provided along the circumferential direction on the side wall of the cylinder 12 near the top end. These 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 lifted from the inner wall of the cylinder 12 is thrown out from the water throwing holes 121 and moves away from the cylinder 12 with a certain initial velocity (the initial velocity is the linear velocity at the position of the water throwing holes 121) and gradually approaches the inner wall of the water tank 11, thereby forming a water curtain for cleaning the gas entering from the air inlet. It should be noted that the plurality of water throwing holes 121 can be arranged in a circle along the circumferential direction of the cylinder 12 evenly or unevenly, and in some examples, multiple circles of water throwing holes 121 can also be arranged along the axis of the cylinder 12 to improve the water washing and purification effect.

[0046] In another implementable method, the water washing component includes a water pipe, the water pipe can include a first end and a second end, the first end of the water pipe can extend into the water stored in the water tank to suck the water at the lower end of the water tank; the second end of the water pipe can extend to the upper end of the water tank. A water pump can be provided on the water pipe, and the water pump can make the water in the water tank flow from the first end to the second end. The water washing component further includes a rotatable disk-shaped component. After the water flowing down from the second end of the water pipe falls on the rotating disk-shaped component, it can be thrown out under the action of centrifugal force, thereby forming a water curtain.

[0047] In yet another possible implementation method, a hollow rotating body can also be used to replace the rotatable disk-shaped component. The upper end of the rotating body is provided with an opening, and a plurality of through holes are provided on the side wall of the rotating body. 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 be thrown out from the through holes along the tangential direction of the rotating body, thereby forming a water curtain.

[0048] In some other possible implementation manners, a rotating water curtain, a water pipe provided with a plurality of water outlets along the length direction, two relatively arranged nozzle structures, an atomizer, etc. can also be adopted to form a water curtain, a water curtain, water mist, etc. in the water tank, so that the air entering the water tank can be washed and purified.

[0049] In summary, there are various water washing components for forming a water curtain with the water in the water tank 11. Hereinafter, the solution of the present application will be introduced by taking the water washing component including the cylinder 12 and the power unit 2 driving the cylinder 12 to rotate as an example. Other structures of the water washing components can be obtained by referring to the present application and will not be elaborated here.

[0050] Continue to refer to Figure 4 , the side wall of the cylinder 12 can be gradually inclined away from the axis direction of the cylinder 12 from top to bottom, that is to say, the cylinder 12 is arranged in a generally conical shape, with the small-diameter end of the cone at the bottom and the large-diameter end of the cone at the top, so as to facilitate the water to climb up along the inner wall of the cylinder 12.

[0051] Continue to refer to Figure 4 , the cylinder 12 can be divided into an upper section 122 and a lower section 123 connected to the lower end of the upper section 122, and the water throwing holes 121 can be arranged on the upper section 122. The upper and lower sections can be made into an integral part by an integral molding method such as injection molding to facilitate the structural stability of the cylinder 12. Of course, the upper and lower sections of the cylinder 12 can also be separate parts, and the two are then assembled together by means of screwing, screwing or welding, etc., and the lower end of the upper section 122 and the upper end of the lower section 123 can be sleeved together, for example, the upper end of the lower section 123 can extend into the lower end of the upper section 122 to enhance the sealing performance between the upper section 122 and the lower section 123.

[0052] It should be noted that when the diameter of the lower end of the upper section 122 is larger than the diameter of the upper end of the lower section 123, the connection between the upper section 122 and the lower section 123 can be connected by a stepped portion. By forming a stepped portion between the upper and lower sections, a temporary storage area can be provided for the water to climb on the inner wall of the cylinder 12, which is beneficial to increasing the amount of water thrown out from the water throwing holes 121.

[0053] Optionally, Figure 5 A cross-sectional view of the cylinder and the power unit is shown to illustrate 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 the upper end face of the outer flange mentioned below, and the axial section may be bent downward relative to the radial section.

[0054] The lower section 123 can be embedded within the flange. Exemplarily, the lower section 123 can include a lower cylinder body and an outer flange. The outer flange can be sleeved on the outer side of the upper end of the lower cylinder body, and one end of the outer flange can be higher than the upper end of the lower cylinder body. The axial section of the inner flange abuts against the top end of the lower cylinder body, and the radial section of the inner flange abuts against the outer flange. Thus, the side of the axial section away from the radial section can be on the same curved surface as the lower cylinder body. This provides a smooth climbing surface for the droplets. Additionally, the outer flange and the inner flange cooperate with each other and block the gaps, which can facilitate improving the sealing performance between the upper section 122 and the lower section 123. lower cylinder body outer flange outer flange lower cylinder body outer flange lower cylinder body outer flange lower cylinder body lower cylinder body upper cylinder body inner flange inner flange radial section axial section radial section outer flange axial section axial section radial section lower cylinder body outer flange inner flange

[0055] It should be noted that, in order to achieve the sealing performance between the upper section 122 and the lower section 123, it is also possible to set a sealing member between the lower section 123 and the upper section 122. The sealing member includes but is not limited to sealing rings, gaskets, etc.

[0056] Optionally, the angle between the side wall of the lower section 123 and the axis of the cylinder body 12 can be greater than the angle between the side wall of the upper section 122 and the side wall of the cylinder body 12. The water rises rapidly in the lower section 123. In the upper section 122, it is convenient for the water to break away from the supporting force or adhesion force of the inner wall of the upper section 122, and it is more convenient to be thrown out from the water throwing holes 121. Additionally, the change in 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 velocity of the water thrown out from the water throwing holes 121 is related to the cross-section of the upper section 122, and the direction of the initial velocity affects the movement trajectory of the thrown-out water, and further affects the contact area between the thrown-out water and the gas. By reasonably setting one or more of the position of the water throwing holes 121 on the cylinder body 12, the rotation speed of the cylinder body 12, and the cross-section of the cylinder body 12 where the water throwing holes 121 are located, the quality of the water curtain formed by the water washing assembly can be improved, thereby improving the air purification effect.

[0057] As Figure 5 shown, the upper end of the cylinder body 12 can be provided with an opening, and an upper cover 13 can be provided at the upper end of the cylinder body 12. The upper cover 13 can be used to close the upper end opening of the cylinder body 12. In addition, when the water in the cylinder body 12 rises to the upper end surface of the cylinder body 12 along with the rotation of the cylinder body 12, the water can be blocked by the upper end surface and fall, so that at least part of the water blocked by the upper end surface flows out from the water throwing holes 121, so as to increase the water output of the water throwing holes 121.

[0058] Optionally, 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 face of the cylinder body 12, and the side wall of the upper cover 13 may be sleeved outside the cylinder body 12. The lower end face of the side wall of the upper cover 13 is located above the water throwing holes 121 to block at least part of the water having an upward movement tendency. It can be understood that at least part of the initial velocity of the water thrown out from the water throwing holes 121 has an upward movement tendency. The movement trajectory of this part of the water may be above the moving range of the gas, and this part of the water may not come into contact with the gas. By appropriately providing a flanging extending away from the cylinder body 12 on the side wall of the upper cover 13, the ability to intercept the water thrown out from the water throwing holes 121 and moving towards the top of the water tank 11 can be improved. The intercepted water may fall onto the outer side wall of the upper section 122 below the side wall of the upper cover 13 and may be thrown out towards the inner side wall of the water tank 11 under the action of centrifugal force as the upper section 122 rotates, so as to form a water curtain, thereby improving the air purification effect.

[0059] Alternatively, the cylinder body 12 and the upper cover 13 may be integrally formed by injection molding or the like. At this time, an upper water blocking protrusion may be provided above the water throwing holes 121, and the upper water blocking protrusion extends from the outer side wall of the cylinder body 12 in a direction away from the cylinder body 12 to block at least part of the water having a tendency to move towards the top end of the water tank 11.

[0060] Alternatively, the upper end of the cylinder body 12 is open. The water throwing holes 121 of the cylinder body 12 are served by the openings at its top end, and water throwing holes 121 may or may not be provided on its side wall. When the cylinder body 12 is driven to rotate, the water sucked into the cylinder body 12 climbs up along its side wall, and all or part of the climbing water may be thrown out from the top opening of the cylinder body 12 to form a water curtain.

[0061] Optionally, as Figure 4 and Figure 5As shown in the figure, a lower water baffle protrusion 14 can be provided below the water throwing holes 121. The lower water baffle protrusion 14 extends from the outer side wall of the cylinder 12 in a direction away from the cylinder 12 to block the water sprayed from the water throwing holes 121 and moving towards the bottom of the water tank 11. It can be understood that at least part of the initial velocity of the water thrown out from the water throwing holes 121 has a tendency to move towards the bottom of the water tank 11. On the one hand, the movement trajectory of this part of the water may be outside the movement range of the gas entering the water tank 11 from the air inlet, and this part of the water may not come into contact with the gas. By providing the lower water baffle protrusion 14, a part of the water moving towards the bottom of the water tank 11 can be intercepted. The intercepted water can accumulate above the lower water baffle protrusion 14 and be thrown out under the action of centrifugal force as the cylinder 12 rotates to form a water curtain, which is beneficial to improving the air purification effect. On the other hand, this part of the water is likely to fall outside the water tank 11 from the air inlet on the side wall of the water tank 11. By providing the lower water baffle protrusion 14, the water splashing out of the water tank 11 from the air inlet can be avoided to a certain extent.

[0062] As Figure 2 shown in the figure, an upper water baffle structure 15 for blocking the air outlet of the water tank 11 is provided at the air outlet of the water tank 11. By providing the upper water baffle structure 15, the water thrown out from the water throwing holes 121 can be blocked so that it will not splash out 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 baffle structure 15 can include the water directly thrown out from the water throwing holes 121 and the water carried by the gas passing through the water curtain.

[0063] Exemplarily, Figure 3 is Figure 2 the enlarged view at A, as Figure 3 shown in the figure, the upper water baffle structure 15 includes a water absorbing member 151. The water absorbing member 151 can be made of a material that can block the passage of water droplets but allow the passage of gas, such as porous polymer materials in the prior art. In some examples, the water absorbing member 151 needs to use a material that blocks water in one direction. For example, it can be reticulated polyurethane foam, sponge, etc.

[0064] In addition, in order to facilitate the installation and support of the water absorbing member 151 and avoid the phenomenon that the water absorbing member 151 sags excessively after absorbing water, the upper water baffle structure 15 may further include 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 installed at the top of the water tank 11 by suitable means such as screwing or snap connection. For example, a placement groove 112 can be provided at the top of the water tank 11, and the support frame can be embedded in the placement groove 112. Exemplarily, the bottom wall of the placement groove 112 can be used to support the bottom wall of the support frame, and the side wall of the support frame can be in interference fit with the side wall of the placement groove 112 to limit the displacement of the support frame circumferentially.

[0065] The support frame can also be set as a mesh structure, and the support frame of this mesh structure can be installed at the top of the water tank 11 in the same way as the above-mentioned hollow columnar support frame. By setting the support frame as a mesh structure, not only can the support force of the support frame on the water absorption member 151 be improved, but also the passage of the purified gas will not be affected. Optionally, the mesh openings of the mesh structure can be hexagonal to improve the stability of the support frame.

[0066] Optionally, the support frame can include a support section 152 and a covering section 153. The support section 152 can include a bottom wall and side walls. The side walls of the support section 152 can be connected to the outer periphery of the bottom wall of the support section 152 and extend upward. The covering section 153 can include a top wall and side walls. The side walls of the covering section 153 can be connected to the outer periphery of the top wall of the covering section 153 and extend downward. The side walls of the support section 152 can be sleeved on the outer sides of the side walls of the covering section 153. The water absorption member 151 can be located in the accommodation space surrounded by the bottom wall of the support section 152, the side walls of the covering section 153, and the top wall of the covering section 153, so that the lower part of the water absorption member 151 is supported by the support section 152, the upper end of the water absorption member 151 is covered by the covering section 153 to define the upper part of the water absorption member 151, and the circumferential direction of the water absorption member 151 is defined by the side walls of the covering section 153 and the side walls of the support section 152, so as to maintain the structural shape of the water absorption member 151 and facilitate the installation of the water absorption member 151.

[0067] In addition, the support section 152 and / or the covering section 153 can have a certain elasticity to improve the sealing performance between the side walls of the support section 152 and the side walls of the covering section 153, so as to prevent water from splashing out of the water tank 11 between the side walls of the support section 152 and the side walls of the covering section 153. In addition, the sealing performance can also be improved by setting a sealing member between the two, or it can also be achieved by the interference fit between the covering section 153 and the support section 152.

[0068] Continue to refer to Figure 3 , when the covering section 153 and the support section 152 are in interference fit, an installation groove can be provided on the outer periphery of the top wall of the covering section 153, and an installation protrusion can be connected to the upper end of the side wall of the support section 152. The installation protrusion can be connected and fitted to the installation groove. Exemplarily, the installation protrusion can be oriented in the axial direction of the support section 152, and the lower end surface of the installation protrusion can be abutted against the bottom wall of the installation groove for installation, so as to prevent the upper end of the covering section 153 from moving. Optionally, the number of installation grooves can be one or more, and multiple installation grooves can be evenly arranged on the outer periphery of the covering section 153.

[0069] Next, the power unit 2 will be described

[0070] Below, taking Figure 5Taking the shown structure as an example, the power unit 2 and its cooperation mode with the cylinder 12 will be explained. That is to say, hereinafter, taking the upper cover 13 provided above and the side wall of the upper cover 13 sleeved outside the cylinder 12 as an example, the situation where the power unit 2 drives the cylinder 12 to rotate will be described. However, it should be understood that the structure of the cylinder 12 is not limited to Figure 5 the structural form in, and it can also be other structures mentioned above.

[0071] Such as Figure 5 shown, the power unit 2 may include a rotating shaft 21, a speed reducer and a motor 22. The motor 22 can be electrically connected to an external power supply, and the motor 22 has a motor shaft 221. The base 5 may include a base 51. The speed reducer may include a first bevel gear 24 rotatably arranged on the base 51 and a second bevel gear 23 rotatably connected to the bottom of the water tank 11. The first bevel gear 24 and the second bevel gear 23 mesh with each other, and the second bevel gear 23 may be located above the first bevel gear 24. It can be understood that the structural form of the speed reducer may include but is not limited to the above structure. By adopting a separable cooperation mode such as the first bevel gear 24 and the second bevel gear 23, it is convenient to disassemble the water tank 11 and the base 51, thereby facilitating the cleaning and / or water filling of the water tank 11. Specifically, when it is necessary to separate the water tank 11 and the base 51, only the first bevel gear 24 and the second bevel gear 23 need to be separated.

[0072] In addition, the motor shaft 221 may be coaxially connected to the first bevel gear 24. The rotating shaft 21 includes a first end and a second end. The first end of the rotating shaft 21 may be coaxially connected to the second bevel gear 23, and the second end of the rotating shaft 21 may be connected to the cylinder 12. Referring to the figure, the first end of the rotating shaft 21 may be the lower end of the rotating shaft 21, and the second end of the rotating shaft 21 may be the upper end of the rotating shaft 21. It can be understood that after the motor 22 is powered on and started, the motor shaft 221 of the motor 22 can drive the first bevel gear 24 to rotate, the first bevel gear 24 can drive the second bevel gear 23 to rotate, and then drive the rotating shaft 21 connected to the second bevel gear 23 to rotate, so that the cylinder 12 connected to the rotating shaft 21 rotates, realizing the functions of sucking water, lifting water and spraying water of the cylinder 12 from the water tank 11.

[0073] Next, the installation of the power unit 2 will be introduced sequentially from bottom to top.

[0074] Installation of the motor 22:

[0075] Such as Figure 5, the motor 22 may include a motor body 222 and a motor shaft 221. The motor body 222 may be suspended and mounted on the base 51 to reduce the impact of the vibration of the motor 22 on the parts below it. Exemplarily, mounting claws 223 extending outward from the motor body 222 may be connected to the side wall of the motor body 222. Fastening holes may be provided on the mounting claws 223, and fasteners may pass through the fastening holes and be connected to the base 51. Schematically, a plurality of mounting claws 223 may be circumferentially arranged outside the motor body 222, and these mounting claws 223 may be evenly distributed on the outer periphery of the motor body 222 to balance the force on the motor 22 seat. The fasteners include but are not limited to bolts, screws, and positioning pins. In addition, the base 51 may be thickened at the connection position with the fasteners to improve the load-bearing capacity of the base 51. Exemplarily, connection columns 511 may be provided on the base 51. One end of the connection column 511 away from the base 51 may abut against the mounting claw 223, and the fastener may pass through the through hole of the mounting claw 223 and be connected to the connection column 511. The number of connection columns 511 may be the same as the number of mounting claws 223.

[0076] In addition, a vibration damping structure may be provided between the upper end of the motor body 222 and the base 51 to reduce the impact of the vibration generated by the motor 22 on the base 51. The vibration damping structure may include a first vibration damping sleeve, and the first vibration damping sleeve may be located between the upper end of the motor body 222 and the lower end face of the base 51. The first vibration damping sleeve may be made of an elastic material such as rubber to be able to attenuate vibration.

[0077] Installation of the first helical gear 24:

[0078] As Figure 5 shown, the first helical gear 24 may be rotatably mounted above the base 51, and the motor shaft 221 may pass through the base 51 and be connected to the first helical gear 24. Among them, the upper end of the motor shaft 221 may be threadedly connected to, so as to realize the installation of the motor shaft 221 and the first helical gear 24. Exemplarily, the motor shaft 221 may include a first section and a second section connected to each other. The first section of the motor shaft 221 is connected to the motor body 222, and the second section of the motor shaft 221 is threadedly connected to the first helical gear 24. The cross-sectional radius of the first section of the motor shaft 221 is greater than the cross-sectional radius of the second section of the motor shaft 221. The lower end of the first helical gear 24 may abut against the upper end face of the first section of the motor shaft 221 to prevent the first helical gear 24 from moving downward. In addition, the rotation direction of the motor shaft 221 may cause the first helical gear 24 to be screwed tightly with the motor shaft 221, so that the motor shaft 221 can drive the first helical gear 24 to rotate.

[0079] Optionally, a vibration damping structure may be provided between the first helical gear 24 and the second helical gear 23 to weaken the influence of the vibration on the first helical gear 24 on the second helical gear 23. The vibration damping structure may include a second vibration damping sleeve, and the second vibration damping sleeve may be sleeved on the first helical gear 24 to increase the contact surface between the second vibration damping sleeve and the first helical gear 24.

[0080] Installation of the second helical gear 23:

[0081] As Figure 5 shown, the second helical gear 23 may be installed at the lower end of the water tank 11. Among them, in order to isolate the power unit 2 from the water in the water tank 11, an installation recess 114 may be provided on the bottom wall of the water tank 11. The installation recess 114 has an opening facing downward, and at least a part of the second helical gear 23 is installed in the installation recess 114. The installation recess 114 may extend towards the inside of the water tank 11 and is located inside the cylinder body 12.

[0082] Optionally, in order to simplify the processing and / or assembly process, a bottom plate 115 may be installed at the bottom end of the water tank 11, and an insertion port 1151 coaxial with the installation recess 114 may be provided on the bottom plate 115. Exemplarily, the bottom plate 115 is detachably connected to the water tank 11. For example, the bottom plate 115 and the water tank 11 are assembled together by screws.

[0083] The second helical gear 23 may be disposed inside the insertion port 1151 to achieve modular installation. Exemplarily, a limiting plate 1152 may be provided in the insertion port 1151, and the limiting plate 1152 and the area below it may define an installation space for the second helical gear 23. The second helical gear 23 may be rotatably disposed in this installation space to limit the movement area of the second helical gear 23.

[0084] Based on the above, the insertion port 1151 is located outside the first helical gear 24, so that the movement areas of the first helical gear 24 and the second helical gear 23 can be defined by the limiting plate 1152, the insertion port 1151, and the base 51. That is to say, the second helical gear 23 is restricted above by the limiting plate 1152 and below by the first helical gear 24. Therefore, the longitudinal movement of the second helical gear 23 will be restricted, thus avoiding the disengagement of the second helical gear 23 and the first helical gear 24 and ensuring the reliability of the transmission.

[0085] The lower end of the rotating shaft 21 may be threadedly connected to the second helical gear 23. Exemplarily, the motor 22 causes the second helical gear 23 to rotate, and the rotation direction of the second helical gear 23 is such that the second helical gear 23 and the rotating shaft 21 are in a mutually tightened state. That is to say, the movement direction of the motor 22 driving the second helical gear 23 may be opposite to the direction in which the rotating shaft 21 disengages from the second helical gear 23, so that the second helical gear 23 drives the rotating shaft 21 to rotate.

[0086] Figure 6 A three-dimensional schematic diagram of a substrate 5 is shown. Figure 8 A top view of a water tank and a bottom plate is shown, as Figure 6 and Figure 8 shown. A vibration damping structure may be provided between the bottom plate 115 and the base 51. The vibration damping structure may include a third vibration damping pad 63. A part of the vibration generated by the motor 22 is transmitted to the base 51. 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 weaken the energy brought by the vibration through deformation, thereby playing a role in vibration damping. Optionally, the third vibration damping pad 63 includes but is not limited to a rubber pad, a spring, an elastic ball, and a spring piece.

[0087] Mounting holes are formed in the base 51, and the lower part of the third vibration damping pad 63 can be embedded in the mounting holes. The lower part of the third vibration damping pad 63 can be in interference fit with the mounting holes to realize the installation of the third vibration damping pad 63.

[0088] The number of the third vibration damping pads 63 is not restrictive, and it can be one or more. For example, four third vibration damping pads 63 are shown in the figure and the figure. Exemplarily, when there are two third vibration damping pads 63, the two third vibration damping pads 63 can be arranged on both sides of the first helical gear 24 or the second helical gear 23; when there are three third vibration damping pads 63, the three third vibration damping pads 63 can be distributed at the three vertices of a triangle to facilitate the installation reliability of the water tank 11; when there are four third vibration damping pads 63, the four third vibration damping pads 63 can be respectively located at the four corners of the base 51 in the shape of an approximate rectangle. Of course, the structure of the third vibration damping pad 63 is not limited to this, and only examples are given here in this embodiment.

[0089] It should be noted that when there are multiple third vibration damping pads 63, at least part of the water tank 11 is suspended on the base 51, that is to say, at the position where the third vibration damping pad 63 is not provided, the base 51 and the water tank 11 do not contact, so as to further reduce the possibility of the vibration on the base 51 being transmitted to the water tank 11.

[0090] Optionally, a plurality of support protrusions 64 are provided on one side of the water tank 11 facing the base 51. The support protrusions 64 are used to bear the pressure of the water tank 11 on the third vibration damping pad 63. Among them, the third vibration damping pad 63 and the support protrusions 64 can be arranged in a staggered manner. The support protrusions 64 can be connected to the bottom wall of the water tank 11, and a third vibration damping pad 63 can be provided below the support protrusions 64 to reduce the vibration at the contact position between the support protrusions 64 and the base 51.

[0091] 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 supporting protrusion 64 in the axial direction of the water tank 11. It should be noted that the third vibration damping pad 63 is subjected to the gravity of the water tank 11. Therefore, after the third vibration damping pad 63 is used for a period of time, the deformation ability of the third vibration damping pad 63 may be weakened. By providing the supporting protrusion 64, the pressure of the water tank 11 on the third vibration damping pad 63 can be reduced, so that the third vibration damping pad 63 can maintain its deformation ability to resist the vibration generated by the base 51.

[0092] In addition, the supporting protrusion 64 may include a cylinder, one end of the cylinder may be connected to the bottom wall of the water tank 11, and the other end of the cylinder may abut against the upper end surface of the base 51. Optionally, the supporting protrusion 64 may include a prism, and the longitudinal section of the prism may be trapezoidally arranged. From the axis of the prism to the edge of the prism, the side wall of the prism gradually inclines towards the water tank 11, that is to say, the cross section of the prism near the water tank 11 is larger than the cross section of the prism near the base 51.

[0093] Optionally, the supporting protrusion 64 may be one or more. For example, Figure 8 four supporting protrusions 64 are provided. Exemplarily, when there are two supporting protrusions 64, the two supporting protrusions 64 may be located on both sides of the first helical gear 24 or the second helical gear 23, and the two supporting protrusions 64 may be symmetrically arranged; when there are three supporting protrusions 64, the three supporting protrusions 64 may be distributed at the three vertices of a triangle to facilitate the installation reliability of the water tank 11; when there are four supporting protrusions 64, the four supporting protrusions 64 may be respectively located at the four vertices of a rectangle, and in some examples, at least two of the four supporting protrusions 64 may be symmetrically arranged. Of course, the structure of the supporting protrusion 64 is not limited to this, and only examples are given here.

[0094] As shown in the figure, a positioning protrusion 513 is provided on the base 51, and a first positioning recess 516 adapted to the positioning protrusion 513 is provided on one side of the water tank 11 facing the base 51 to achieve quick installation between the water tank 11 and the base 51. Optionally, the positioning protrusion 513 is conical, and the radius of the cross section of the positioning protrusion 513 gradually increases in the direction away from the water tank 11, so as to save effort when removing the water tank 11 from the base 51.

[0095] Optionally, at least two positioning protrusions 513 are provided on the base 51, and these positioning protrusions 513 are respectively located on both sides of the second helical gear 23. The vibration at the second helical gear 23 is relatively large. The vibration can be transmitted in the vertical direction and can also be transmitted along the circumference of the base 51. When the vibration is transmitted to the positioning protrusion 513, the vibration can be weakened by the height change of the cross section of the positioning protrusion 513. In addition, by providing a plurality of positioning protrusions 513, the rotation of the water tank 11 can be restricted.

[0096] Installation of the rotating shaft 21:

[0097] As Figure 5 shown, the lower end of the rotating shaft 21 can be connected to the second helical gear 23, and the rotating shaft 21 can sequentially pass through the insertion opening 1151 and the installation recess 114 from bottom to top and be connected to the upper end of the cylinder body 12. That is to say, the rotating shaft 21 can be rotatably installed in the insertion opening 1151 and the installation recess 114, and the installation recess 114 or the insertion opening 1151 can perform radial limitation on the rotating shaft 21 to prevent the rotating shaft 21 from being bent and damaged. Exemplarily, a bearing 25 can be provided in the insertion opening 1151, and the rotating shaft 21 can be rotatably arranged inside the insertion opening 1151 through the bearing 25, and the bearing 25 can play a role of radial support for the rotating shaft 21. Optionally, the limiting plate 1152 can divide the insertion opening 1151 into a first area and a second area arranged side by side in the up-down direction. The second helical gear 23 can be located in the first area below the limiting plate 1152, and the bearing 25 can be located in the second area above the limiting plate 1152 to facilitate modular installation.

[0098] Optionally, an oil seal 27 and a gasket 26 can be provided in the second area, and the gasket 26 can be located between the bearing 25 and the oil seal 27. The gasket 26 can isolate the oil seal 27 and the bearing 25 and prevent the rolling elements of the bearing 25 from slipping out. The oil seal 27 can seal the rotating shaft 21 to prevent dust, liquid, etc. from entering.

[0099] Optionally, a bearing 25 can also be provided at the upper end of the installation recess 114 to provide radial support for the rotating shaft 21. The upper end of the installation recess 114 can also be provided with the above-mentioned gasket 26 and oil seal 27.

[0100] It should be noted that the bearings 25, gaskets 26, and oil seals 27 on the installation recess 114 and the insertion opening 1151 can be symmetrically arranged.

[0101] As Figure 5 shown, a connecting member 28 can be provided between the side wall of the upper end of the rotating shaft 21 and the inner wall of the cylinder body 12 to connect the rotating shaft 21 and the cylinder body 12 together through the connecting member 28. The connecting member 28 can be arranged above the installation recess 114 (as Figure 5 shown), the connecting member 28 can include a sleeve 281 and a connecting piece 282. The sleeve 281 can be sleeved on the outside of the first end of the rotating shaft 21, and both sides of the connecting piece 282 are respectively connected to the outside of the sleeve 281 and the inner wall of the cylinder body 12. In this way, the connection between the rotating shaft 21 and the cylinder body 12 can be realized. To improve the sealing performance, the sleeve 281 can be integrally formed with the bottom wall of the water tank 11 by means of injection molding or the like to form an integral part.

[0102] The connecting piece 282 may be provided with one or more. When there are multiple connecting pieces 282, the multiple connecting pieces 282 may be evenly distributed in the circumferential direction of the rotating shaft 21 to improve the connection strength between the connecting member 28 and the cylinder 12. At the same time, the connecting piece 282 can also play a supporting role for the cylinder 12 to improve the structural strength of the cylinder 12.

[0103] Continue to refer to Figure 5 , the top end of the rotating shaft 21 may be connected to the upper cover 13 to drive the upper cover 13 to rotate simultaneously. Exemplarily, an installation block may be provided on the inner wall of the upper cover 13, the installation block extends downward, and the upper end of the rotating shaft 21 may be threadedly connected to the installation block.

[0104] In addition, as Figure 5 shown, a reinforcing rib may be provided between the outer side wall of the installation block and the upper cover 13 to support the installation block and strengthen the strength of the installation block. Exemplarily, one end of the reinforcing rib is connected to the outer side wall of the installation block, and the other end of the reinforcing rib extends toward the inner wall of the upper cover 13 and is connected to the inner wall of the upper cover 13. Optionally, the reinforcing rib may be arranged around the circumference of the installation block to enhance the circumferential strength of the installation block.

[0105] Optionally, as Figure 5 shown, a ring-shaped protrusion may be connected to the bottom wall of the upper cover 13, and the ring-shaped protrusion may extend toward the bottom end of the cylinder 12. There is a gap between the ring-shaped protrusion and the side wall of the upper cover 13, and the top end of the side wall of the cylinder 12 may extend into this gap.

[0106] The following describes the cooperation mode between the water tank 11 and the base 51:

[0107] Refer to Figure 1 and Figure 6 shown, the base 51 may include a bottom wall and a side wall, the side wall of the base 51 may be connected to at least part of the outer circumference of the bottom wall of the base 51 and extend upward. Optionally, at least part of the water tank 11 may be embedded in the base 51, and a gap is formed between the outer wall of the water tank 11 and the side wall of the base 51. By reducing the contact between the outer wall of the water tank 11 and the side wall of the base 51, the transmission of vibration is avoided. Optionally, a damping pad may be provided between the outer wall of the water tank 11 and the side wall of the base 51.

[0108] In addition, as Figure 1 , Figure 6 and Figure 8As shown, the cross-section of the base 51 may include an arc portion and a rectangular portion, and the arc portion corresponds to and communicates with the vertical portion. The shapes of both ends of the base 51 can be set to be inconsistent, so as to facilitate the user to find the positioning accurately, which is beneficial to the installation between the water tank 11 and the base 51. In addition, one side of the base 51 is open, and a pick-up projection 514 is provided at the opening. Both ends of the pick-up projection 514 are connected to the groove wall of the base 51. The pick-up projection 514 and the side wall of the base 51 enclose a receiving space, and at least part of the bottom plate 115 and the first helical gear 24 can be located in the receiving space, and the receiving space can play a role in circumferentially limiting the bottom plate 115. A relief depression adapted to the shape of the pick-up projection 514 may be provided on the bottom plate 115, so as to facilitate the user to pick up the water tank 11.

[0109] Optionally, a take-out groove 515 may be provided on the base 51. The take-out groove 515 may be opened on the side of the pick-up projection 514 facing away from the receiving space, and the bottom end of the take-out groove 515 may be lower than the upper end surface of the pick-up projection 514. At least part of the bottom plate 115 and the water tank 11 are located above the pick-up groove. A hand-holding projection 1153 may be provided on the bottom plate 115 opposite to the pick-up groove, and the hand-holding projection 1153 may extend towards the pick-up groove. When the water tank 11 is to be taken out, the user can put the hand into the take-out groove 515, hold the hand-holding projection 1153 upward, and pull it outward, so that the first helical gear 24 and the second helical gear 23 can be separated, and the separation of the water tank 11 and the base 51 can be easily realized.

[0110] Optionally, as Figure 1 and Figure 8 shown, hand-holding depressions 116 may be provided on two opposite side walls of the water tank 11, and the hand-holding depressions 116 may extend towards the inside of the water tank 11. When the user takes out the water tank 11, the hand can also be put into the hand-holding depressions 116 and the water tank 11 can be pulled outward.

[0111] Since the base 51 is used to carry the water tank 11, the power unit 2 and the water washing unit 1. Therefore, in order to improve the stability and structural strength of the base 51 so as to carry the weight of the motor 22 seat and the water tank 11, it can be realized through the following base strengthening structure.

[0112] Figure 9 A perspective view of a base 51 and a water tank 11 is shown. Referring to Figure 5 and Figure 9 shown, the base strengthening structure includes auxiliary ribs 5121. The auxiliary ribs 5121 may be connected to the base 51 and extend towards the mounting claw 223. One side of the auxiliary ribs 5121 may be connected to the connecting column 511 mentioned above to provide support for the connecting column 511. Among them, one or more auxiliary ribs 5121 may be provided, and a plurality of auxiliary ribs 5121 may be evenly distributed in the circumferential direction of the connecting column 511 to uniformly support the circumferential direction of the connecting column 511.

[0113] Optionally, the height of the auxiliary rib 5121 may be higher than the height of the connecting column 511. A limiting groove may be provided at the upper end of the auxiliary rib 5121, and the side of the limiting groove facing the connecting column 511 has an opening. The bottom wall of the limiting groove may abut against the upper end of the mounting claw 223 (or the bottom wall of the limiting groove may be flush with the bottom end of the connecting column 511) so as to limit the mounting claw 223 in the longitudinal direction. The groove wall of the limiting groove may abut against the side wall of the mounting claw 223 so as to limit the outer periphery of the mounting claw 223.

[0114] Understandably, the mounting claw 223 may include a first side wall, a second side wall, a third side wall, and a fourth side wall. Among them, the first side wall and the second side wall are oppositely arranged, the third side wall and the fourth side wall are oppositely arranged, and the first side wall may be connected to the motor body 222. Exemplarily, three auxiliary ribs 5121 may be connected to one connecting column 511, and the three auxiliary ribs 5121 may be evenly distributed on the side wall of the connecting column 511. Limiting grooves are provided at the upper ends of the three auxiliary ribs 5121, and the second side wall, the third side wall, and the fourth side wall of the mounting claw 223 may respectively abut against the three groove walls of the three limiting grooves so as to limit the second side wall, the third side wall, and the fourth side wall of the mounting claw 223. It should be noted that this is only an illustrative description, and the number of the auxiliary ribs 5121 is not specifically limited.

[0115] Optionally, the base strengthening structure may further include a connecting protrusion 5122. A connecting protrusion 5122 may be provided between at least some adjacent auxiliary ribs 5121 that are connected to different connecting columns 511 so as to connect several connecting columns 511 into a whole, thereby improving the structural strength of the base 51. The connecting protrusion 5122 may be arc-shaped, and the motor 22 may be located within the connecting protrusion 5122. Optionally, the height of the connecting protrusion 5122 may be less than the height of the auxiliary rib 5121 so as to reduce unnecessary structural weight while ensuring the strength of the connecting column 511.

[0116] Optionally, as Figure 9 shown, the base strengthening structure may further include a support rib 5123. The support rib 5123 may be connected to the base 51 and extend in the direction of the mounting claw 223. One side of the support rib 5123 may be connected to the auxiliary rib 5121 so as to provide support for the auxiliary rib 5121 in the thickness direction of the auxiliary rib 5121. The support rib 5123 may span the height direction of the auxiliary rib 5121 (that is, the support rib 5123 may be connected to the highest height of the auxiliary rib 5121) so as to better support the position where the connecting column 511 and the mounting claw 223 are connected.

[0117] Optionally, the base strengthening structure may further include radial ribs 5124. The radial ribs 5124 may be connected to the base 51 and extend towards the direction of the mounting claws 223. One end of the radial rib 5124 may be connected to the outer sidewall of the connecting protrusion 5122 or the auxiliary rib 5121, and the other end of the radial rib 5124 may extend to the edge of the base 51 to improve the overall structural strength of the base 51. Among them, there may be multiple radial ribs 5124, and the multiple radial ribs 5124 may be evenly distributed on the outer side of the connecting protrusion 5122 or the auxiliary rib 5121. In addition, a wire passing groove 5125 may be provided on the radial rib 5124 for wires or data lines to pass through the wire passing groove 5125. A limiting protrusion 5126 may be provided on the base 51. The limiting protrusion 5126 may include a vertical section and a horizontal section. The vertical section may extend towards the direction of the mounting claws 223, and the cables for power supply and / or communication may pass through the gap between the horizontal section and the base 51 to limit the movement of the cables longitudinally.

[0118] Optionally, as Figure 9 shown, the base strengthening structure may further include circumferential ribs 5127. The circumferential ribs 5127 may be sleeved on the outer side of the connecting protrusion 5122 and / or the auxiliary rib 5121, and a circumferential rib 5127 may be provided between two adjacent radial ribs 5124 to strengthen the connection between the multiple radial ribs 5124, thereby strengthening the structural strength of the base 51. Among them, at least one circumferential rib 5127 may be provided between two adjacent radial ribs 5124. It can be understood that the more circumferential ribs 5127 there are between two adjacent radial ribs 5124, the more stable the structure of the radial ribs 5124 is.

[0119] Optionally, as Figure 5 shown, damping protrusions may be provided on the base 51. The damping protrusions may be arranged in a ring shape and extend towards the direction of the motor main body 222. The first damping sleeve mentioned above may be sleeved on the upper end of the motor 22 seat and embedded in the damping protrusions, and the damping protrusions may limit the damping sleeve. By providing the damping sleeve, the contact area with the motor main body 222 can be increased, thereby improving the damping effect.

[0120] As Figure 5 shown, a water outlet hole 722 is directly opened on the base 51 below the water tank 11, and a water outlet pipe is connected to the water outlet hole 722. Excessive water can overflow from the air inlet to the gap between the base 5 and the water tank 11 and flow down along the side wall of the base 5 into the water outlet hole 722.

[0121] It should be noted that the overall air flow direction of the air purification device can be from the side and then out from the top or side, or it can also be from the bottom and then out from the top or side. Different air inlet methods result in different air inlet parts 3, and since the air inlet part 3 is provided relying on the base body 5, the shapes of the base body 5 corresponding to different air inlet methods can be different. Additionally, although the air inlet methods are different, the structural forms of the power part 2, the water tank 11, and the water washing part 1 mentioned above can be the same.

[0122] The base body 5 includes the base 51 and the base shell mentioned above. The base 51 can be used for the installation of the power part 2, the water tank 11, and the water washing part 1, and the base shell is used for the installation of the air inlet part 3. The base 51 is located inside the base shell. Next, in combination with the air inlet from the side and the air outlet from the side, the air inlet part 3 and the air outlet part 4 of the air purification device will be specifically described.

[0123] Figure 1 and Figure 6 The shown base body takes the air purification device with air inlet from the side as an example. As shown in Figure 1 and Figure 6 The base body 5 can include a first base shell 53 and a base 51. The first base shell 53 can include a top wall and a side wall. The inner side of the top wall of the first base shell 53 can be connected to the outer periphery of the upper end side wall of the base 51, and the side wall of the first base shell 53 can be connected to the outer side of the top wall of the first base shell 53 and extend downward. A radial rib 5124 mentioned above can be provided between the side wall of the first base shell 53 and the side wall of the base 51. Grooves can be provided on the radial rib 5124 for the passage of cables for power supply and / or communication, and it can also achieve the purpose of weight reduction.

[0124] Figure 10 Fig. shows a top view of an air purification device. Figure 11 shows Figure 10 a partial three-dimensional cross-sectional view at M-M, as shown in Figure 1 and Figure 11 The air inlet part 3 can further include a primary filter assembly 31 to primarily filter the gas to enter the water tank 11. Figure 7 Fig. shows a three-dimensional schematic diagram of a primary filter assembly 31. As shown in Figure 7 The primary filter assembly 31 can include a filter layer 311 and a filter frame 312. The filter layer 311 can be sleeved on the outside of the air inlet of the water tank 11, and the filter frame 312 can be sleeved on the outside of the filter layer 311. When the water tank 11 is mainly formed by connecting an arc part and a vertical part, the air inlet can be provided on the arc part, and the primary filter assembly 31 is arranged on the outside of the arc part of the water tank 11. For the convenience of description, hereinafter, the arc part of the water tank 11 is defined as the front end of the water tank 11, and the vertical part of the water tank 11 is defined as the rear end of the water tank 11.

[0125] Understandably, through holes may be provided in the filter rack 312 so that external gas can enter through the through holes, pass through the filter layer 311 for primary filtration, and then enter the water tank 11 from the air inlet of the water tank 11 and be purified by the water curtain. Exemplarily, the filter rack 312 may include side walls, an upper wall, and a bottom wall. The upper wall and the bottom wall of the filter rack 312 are respectively connected to both ends of the side wall of the filter rack 312, and both can extend in the axial direction of the water tank 11. The side wall, the upper wall, and the bottom wall of the filter rack 312 define an installation space for installing the filter layer 311.

[0126] Optionally, referring to Figure 1 and Figure 11 As shown, the upper wall of the filter rack 312 may be connected to the upper end of the water tank 11. Exemplarily, the side wall at the upper end of the water tank 11 is provided in a stepped shape to form a placement groove 112 for connecting the upper water retaining structure 15. Understandably, the bottom wall of the placement groove 112 may abut against the upper wall of the filter rack 312 to limit the longitudinal height of the filter rack 312.

[0127] Optionally, continuing to combine Figure 1 and Figure 11 It can be obtained that the bottom wall of the filter rack 312 may be connected to the upper end surface of the first base shell 53, and the first base shell 53 can be used to support the filter rack 312. Additionally, in the radial direction, the length of the bottom wall of the filter rack 312 may exceed the thickness of the filter layer 311. That is to say, at least part of the bottom wall of the filter rack 312 is not covered by the filter layer 311. A limiting plate 101 may be connected to the outer side wall of the water tank 11, and the limiting plate 101 may abut against the upper end surface of the part of the bottom wall of the filter rack 312 that exceeds the filter layer 311 to achieve positioning of the filter rack 312 in the longitudinal direction. Additionally, an abutting protrusion 102 may be connected to the side wall of the water tank 11, and the abutting protrusion 102 may extend towards the outside of the water tank 11, and the abutting protrusion 102 may abut against one side in the thickness direction of the filter layer 311. Understandably, the side wall of the filter rack 312 and the abutting protrusion 102 can limit the displacement of the filter layer 311 in the thickness direction.

[0128] Optionally, combining Figure 6 and Figure 7 , a limiting protrusion 531 may be provided on the upper end surface of the front end of the first base shell 53, and the inner wall of the limiting protrusion 531 may abut against the outer side wall of the front end of the filter rack 312 to limit the radial position of the filter rack 312. Exemplarily, the filter rack 312 and the filter layer 311 may be designed in an arc shape, and the shape of the limiting protrusion 531 may match the shape of the filter layer 311 to fit against the outer side wall of the filter rack 312.

[0129] Optionally, positioning holes 532 may be provided on the defined protrusion 531. A positioning plate 313 may be connected to the outer side wall of the filter rack 312, and the positioning plate 313 may extend in a direction away from the axis of the water tank 11. The positioning plate 313 may be connected to the positioning hole 532 in a matching manner. Exemplarily, at least a part of the positioning plate 313 may pass through the positioning hole 532. It can be understood that when installing the filter rack 312 onto the first base case 53, it is only necessary to extend the positioning plate 313 out of the positioning hole 532, which facilitates the positioning and installation of the filter rack 312. Additionally, the positioning hole 532 may be arranged in a direction parallel to or coinciding with the symmetry axis of the first base case 53, so that when installing the filter rack 312, it is only necessary to push the positioning plate 313 on the filter rack 312 through the positioning hole 532 along this direction, thereby enabling quick installation.

[0130] Optionally, continuing to combine Figure 5 and Figure 9 it can be obtained that a defined depression 533 may be provided on the upper end surface at the rear end of the first base case 53, and a plug-in protrusion 314 may be provided on the bottom wall of the filter rack 312. The plug-in protrusion 314 may be connected to the defined depression 533 in a matching manner. Exemplarily, the plug-in protrusion 314 may include a vertical section connected to the bottom wall of the filter rack 312 and a horizontal section bent towards the front end of the filter rack 312 relative to the vertical section. The upper end of the defined depression 533 may be open, and the defined depression 533 includes a groove wall and a groove bottom. A jack 534 may be provided on the groove wall of the defined depression 533 at the front end, and the horizontal section of the plug-in protrusion 314 may be inserted into the jack 534 to achieve the limitation and installation of the filter rack 312. It can be understood that the horizontal section of the plug-in protrusion 314 may slide on the groove bottom of the defined depression 533 to limit the movement track of the filter rack 312.

[0131] Optionally, a front protrusion 535 is provided on the top surface at the front end of the first base case 53, and a groove matching the front protrusion 535 may be provided on the bottom wall of the filter rack 312 to at least partially limit the front-back movement of the filter rack 312. In some examples, the cross-section of the front protrusion 535 gradually increases from top to bottom, that is to say, the front protrusion 535 is generally conical.

[0132] Optionally, a storage depression 536 for installing the controller 182 of the water shortage reminder device may be provided on the first base case 53 (an opening is also provided on the corresponding surface of the base 51), and the bottom wall of the filter rack 312 may be used to block the storage depression 536 to limit the wires connected to the controller 182. A wiring hole 537 may be provided on the first base case 53 to facilitate the routing of the cable.

[0133] Regarding the air outlet part 4:

[0134] As Figure 11As shown, the air outlet part 4 may include an air outlet cover 41. The air outlet cover 41 may be hollow, and an opening communicating with the upper end of the water tank 11 may be provided at the lower end of the air outlet cover 41. A fan may be provided in the air outlet cover 41 to guide gas into the water tank 11 and pass through the water curtain formed in the water tank 11. An air outlet is provided on the air outlet cover 41 for the outlet of the gas.

[0135] Exemplarily, the type of the fan may be centrifugal, axial flow, diagonal flow (mixed flow), cross flow, etc. Figure 1 Taking a centrifugal fan as an example, other types of fans can be referred to. Among them, the centrifugal fan 431 may include an impeller 4311 and a centrifugal motor 4312 for driving the impeller 4311. The impeller 4311 may include a hub and fan blades. It can be understood that when the centrifugal motor 4312 starts, the impeller 4311 rotates, and the air in the flow channel (an adjacent two fan blades can form a flow channel) moves outward under the action of centrifugal force, generating a vacuum degree in the center of the impeller 4311. Therefore, the gas coming out of the upper end opening of the water tank 11 is sucked into the impeller 4311. After the sucked gas turns 90° at the inlet of the impeller 4311, it enters the flow channel and obtains 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 cover 41 and is discharged from the air outlet of the air outlet cover 41 after centralized diversion.

[0136] It can be understood that the fan blades may be inclined, and the inclination direction of the fan blades may be opposite to the rotation direction of the impeller 4311. Hereinafter, the case where the fan blades 43111 are arranged clockwise and the impeller 4311 rotates counterclockwise will be taken as an example for description. The rotation direction of the impeller 4311 here can also be clockwise. When the impeller 4311 rotates clockwise, the setting mode of the air outlet cover 41 can be referred to

[0137] Such as Figure 1 and Figure 11 As shown, for the convenience of the installation of the fan, the air outlet cover 41 may include an upper cover body 433 and a lower cover body 432. The upper cover body 433 is detachably connected to the lower cover body 432. A central hole penetrating through may be provided on the lower cover body 432, and the lower end of the central hole may communicate with the upper end opening of the water tank 11.

[0138] The structure of the lower cover body 432 will be described from bottom to top below.

[0139] Such as Figure 1 and Figure 11 As shown, the lower cover body 432 may include a mounting part and a guiding part. The mounting part may be used to connect to the water tank 11 and / or the filter rack 312, and the guiding part is used to guide the flow direction of the gas in the air outlet cover 41. Exemplarily, Figure 12 The schematic diagram showing the connection position of a part of the water tank 11 and the lower cover body 432 is shown. Such as Figure 11 and Figure 12As shown, the installation part may include a first installation section 4321. The first installation section 4321 may be arranged in a ring shape and sleeved on the outer side wall of the upper end of the water tank 11. A vibration damping structure may be provided between the outer side wall of the upper end of the water tank 11 and the inner wall of the first installation section 4321. The vibration damping structure may include a vibration damping gasket 65 to reduce the noise at the connection position between the first installation section 4321 and the water tank 11. In addition, the vibration damping gasket 65 may also play a sealing role to prevent the splashed washing liquid from flowing to the outside of the lower cover 432.

[0140] In addition, when a primary filter assembly 31 is provided on the side wall of the water tank 11, the installation part may further include a second installation section 4322. The second installation section 4322 may include a side wall and an upper wall. The upper wall of the second installation section 4322 may be bent outward relative to the first installation section 4321 (the "outside" here refers to the outside of the lower cover 432), and the side wall of the second installation section 4322 may be bent downward relative to the upper wall of the second installation section 4322. The upper wall of the second installation section 4322 may abut against the upper end face of the filter rack 312, and the side wall of the second installation section 4322 may be sleeved on the outer side of the upper end of the filter rack 312. In this way, the upper and lower ends of the filter rack 312 are respectively restricted by the upper wall of the second installation section 4322 and the upper end face of the first base shell 53, and the inner and outer sides of the filter rack 312 are respectively restricted by the water tank 11 and the side wall of the second installation section 4322, so as to realize the restriction of the second installation section 4322 on the height direction of the filter rack 312 and the restriction on the thickness direction of the filter rack 312 (i.e., the radial direction of the filter rack 312).

[0141] In addition, as Figure 1 shown, a first reinforcing plate 4341 may be provided between the upper walls of the first installation section 4321 and the second installation section 4322 to strengthen the connection between the first installation section 4321 and the second installation section 4322.

[0142] Optionally, as Figure 11 shown, the guiding part may include a concentration plate 4323 connected to the outer periphery of the upper end of the first installation section 4321. A concentration hole may be provided through the concentration plate 4323, and the concentration hole may correspond to the air inlet of the impeller 4311. The gas entering the first installation section 4321 may pass through the concentration hole to reduce the radius of the cross-sectional area of the lower cover 432, so that the gas is concentrated at the air inlet position of the impeller 4311, which is beneficial to the gas entering the impeller 4311.

[0143] The guiding part may further include a first guiding protrusion 4324 arranged in a ring shape. The first guiding protrusion 4324 is located below the impeller 4311, and can be connected to the circumference of the central hole, and can be bent towards the inside of the impeller 4311 to guide the purified gas into the impeller 4311 of the centrifugal fan 431. At least part of the first guiding protrusion 4324 is embedded in the impeller 4311 of the centrifugal fan 431 to facilitate the smooth docking of the radial section of the first guiding protrusion 4324 and the impeller 4311. It can be understood that the first installation section 4321, the central plate 4323, and the first guiding protrusion 4324 can define a first guiding air duct.

[0144] In addition, Figure 13 shows Figure 1 a transverse sectional view at the middle position of the first air outlet hole 43281, as Figure 11 and Figure 13 shown, an equilibrium plate 4325 can be connected to the inner wall at the upper end of the first guiding protrusion 4324 to disperse the gas into several regions to achieve uniform air outlet. Here, "uniform air outlet" means that the gas flow rates in the regions at the same radial position can be the same. Exemplarily, the equilibrium plate 4325 may include a circumferential edge strip 43251 and a radial edge strip 432542. The circumferential edge strip 43251 is arranged in a ring shape, and can be located inside the first guiding protrusion 4324 and be concentric with the first guiding protrusion 4324. The radial edge strip 432542 is arranged along the radial direction of the first guiding protrusion 4324 and can connect the first guiding protrusion 4324 and the circumferential edge strip 43251 together to form several regions.

[0145] It can be understood that, as Figure 11 shown, the hub of the centrifugal fan 431 may include an air inlet section and a connection section located above the air inlet section. The air inlet section is used to guide the gas into, and the connection section is used to install the centrifugal motor 4312. The air inlet section and the connection section can be connected by fan blades. Among them, from top to bottom, the air inlet section gradually bends towards the outside of the impeller 4311 to guide the gas to the outside of the impeller 4311.

[0146] In addition, as Figure 11 shown, when designing the lower cover 432, in order to fit more closely to the air inlet section of the centrifugal fan 431 or to guide the gas to the outside of the impeller 4311, it can be achieved through the following settings. Exemplarily, the guiding part may include a second guiding protrusion 4326. The second guiding protrusion 4326 is arranged in a ring shape. The second guiding protrusion 4326 can be sleeved on the outside of the air inlet section of the hub, and can be connected to the central plate 4323 and can be bent towards the outside of the impeller 4311. A second guiding channel 422 is defined between the second guiding protrusion 4326 and the air inlet section of the hub.

[0147] Exemplarily, the second guiding protrusion 4326 may include an axial segment and a radial segment. The axial segment of the second guiding protrusion 4326 may be connected to the concentration plate 4323 and extend upward. The radial segment of the second guiding protrusion 4326 may be bent relative to the axial segment of the second guiding protrusion 4326 toward the outer side of the impeller 4311. The air inlet section of the hub may be located between the first guiding protrusion 4324 and the second guiding protrusion 4326.

[0148] In addition, an air outlet hole 43231 may be provided on the concentration plate 4323 located between the air inlet section of the hub and the second guiding protrusion 4326. It can be understood that a part of the gas coming out of the water tank 11 passes through the above air outlet hole 43231 and enters the second guiding channel 422. Another part of the gas coming out of the water tank 11 can enter the impeller 4311 through the first guiding air duct and converge with the gas flowing out of the second guiding channel 422 through the flow channel of the impeller 4311.

[0149] Optionally, the guiding part may further include a third guiding protrusion 4327 and a fourth guiding protrusion 4328. The third guiding protrusion 4327 may be connected to the second guiding protrusion 4326 and extend toward the outer side of the lower cover 432. The fourth guiding protrusion 4328 may be bent upward relative to the third guiding protrusion 4327, and a first air outlet hole 43281 may be provided on the fourth guiding protrusion 4328. The third guiding protrusion 4327 and the fourth guiding protrusion 4328 may limit the third guiding channel 423 to lead the gas out of the air outlet cover 41 from the first air outlet hole 43281. In addition, the upper end of the first air outlet hole 43281 located on the lower cover 432 may be open, and the opening height of the first air outlet hole 43281 may be greater than the height of the flow channel of the impeller 4311 to ensure that the gas flowing out of the flow channel of the impeller 4311 can smoothly enter the first air outlet hole 43281.

[0150] Optionally, as Figure 1 、 Figure 11 and Figure 13 shown, there may be one first air outlet hole 43281, or there may be multiple first air outlet holes 43281. The case where there is one first air outlet hole 43281 is very common and will not be elaborated here. Figure 11 As shown, when there are multiple first air outlet holes 43281, the fourth guiding protrusion 4328 between two adjacent first air outlet holes 43281 may be bent in a direction gradually away from the outer circumference of the impeller 4311 along the rotation direction of the impeller 4311, so as to gradually guide the gas flow direction and reduce the energy loss between the gas and the fourth guiding protrusion 4328. In addition, the multiple first air outlet holes 43281 may be symmetrically arranged to balance the gas flow rate and keep the washed air stable.

[0151] Understandably, the water-washing air purification device of the present application can be applied to floor-standing air-conditioning equipment, so it meets the user's requirements for the air outlet height. The air outlet of the air outlet cover 41 can be adjusted upward to increase the air outlet height. Exemplarily, as Figure 1 and Figure 11 shown, the fourth guiding protrusion 4328 can be provided with a side guiding recess 43282. The side guiding recess 43282 can extend towards the outside of the lower housing 432. A second air outlet hole 43283 can be provided on the side guiding recess 43282. The air outlet height of the second air outlet hole 43283 can be higher than that of the first air outlet hole 43281. Among them, from the axis of the lower housing 432 to the outer peripheral direction of the lower housing 432, the bottom wall of the side guiding recess 43282 can gradually incline upward to guide the gas located in the third guiding channel 423 upward. Understandably, the side wall and the bottom wall of the side guiding recess 43282 can define a fourth guiding channel 424. The fourth guiding channel 424 can communicate with the third guiding channel 423, guide the gas upward, and flow out from the second air outlet hole 43283.

[0152] In addition, as Figure 1 shown, a lifting plate 43284 can also be provided in the first air outlet hole 43281. Along the rotation direction of the impeller 4311, the lifting plate 43284 gradually inclines upward to obtain gas moving obliquely upward. The lifting plates 43284 can be evenly distributed in the height direction of the first air outlet hole 43281 to facilitate uniform air outlet.

[0153] Optionally, as Figure 13 shown, for adjacent first air outlet holes 43281 and second air outlet holes 43283, along the rotation direction of the impeller 4311, from one first air outlet hole 43281 (or second air outlet hole 43283) to another second air outlet hole 43283 (or first air outlet hole 43281), the fourth guiding protrusion can be bent towards a direction gradually away from the outer peripheral direction of the impeller 4311.

[0154] Optionally, as Figure 1 shown, a strengthening structure can be connected to the outside of the second guiding protrusion 4326. The strengthening structure can be a second strengthening plate 54344342. The upper and lower ends of the second strengthening plate 54344342 can be respectively connected to the third guiding protrusion 4327 and the first guiding protrusion 4324 to improve the bearing capacity of the lower housing 432.

[0155] Optionally, as Figure 13As shown, the distribution of the first air outlet holes 43281 and the second air outlet holes 43283 on the upper cover body 433 can be symmetrically arranged. Two first air outlet holes 43281 or two second air outlet holes 43283 can be arranged on both sides of the symmetry axis, so as to improve the air outlet balance of the air outlet cover 41. Exemplarily, two second air outlet holes 43283 can be located at the front end of the lower cover body 432, and two first air outlet holes 43281 can be located at the rear end of the lower cover body 432. Among them, the front end direction of the lower cover body 432 is the same as the front end direction of the water tank 11, and the rear end direction of the lower cover body 432 is the same as the rear end direction of the water tank 11.

[0156] In order to meet the above symmetry requirements, 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 protrusion 4328 can have corresponding curve turning changes. Here, taking the fourth guiding protrusion 4328 between two first air outlet holes 43281 as an example, a simple description is given. Among them, a first air inlet can be defined between two adjacent fourth guiding protrusions 4328 arranged in parallel.

[0157] Exemplarily, the first air outlet hole 43281 can include a first end and a second end. Along the rotation direction of the impeller 4311, the first end can be located before the second end. As Figure 12 shown, the second end of the first air outlet hole 43281 on the right side can be connected to the first end of the first air outlet hole 43281 on the left side through the fourth guiding protrusion 4328. The fourth guiding protrusion 4328 can include a first straight section 43285, an arc section 43286 and a second straight section 43287. The first straight section 43285 can be connected to the second end of the first air outlet hole 43281 on the right side, and the second straight section 43287 can be connected to the first end of the second air outlet hole 43283. The first straight section 43285 and the second straight section 43287 can be symmetrically arranged to determine the symmetry reference of two symmetric first air outlet holes 43281. The arc can include a first end and a second end. Against the rotation direction of the impeller 4311, the first end of the arc section 43286 can be connected to the second straight section 43287, and the second end of the arc section 43286 can be bent towards the direction gradually approaching the impeller 4311, and the second end of the arc section 43286 can be lower than the first end of the arc section 43286. So that as the impeller 4311 rotates, the gas can smoothly enter the first air outlet hole 43281 on the left side; there can be a transition section 43288 between the second end of the arc section 43286 and the first straight section 43285 to facilitate the smooth entry of the gas into the first air outlet hole 43281 on the right side.

[0158] Optionally, by Figure 13It can be seen that the transition section 43288 has obvious mutation points, that is, obvious angle change points. Therefore, in order to improve the structural strength of the fourth guiding protrusion 4328 at the position of the transition section 43288, that is, in order to improve the structural strength at the cross-section mutation point, the guiding part may further include a transition plate, and the transition plate can connect the transition section 43288 and at least part of the arc section 43286.

[0159] Next, the upper housing 433 will be described:

[0160] As Figure 1 and Figure 11 shown, the upper housing 433 may include an upper housing plate 4331, and the upper housing plate 4331 can be used to cover the central hole on the lower housing 432. The fan can be suspended and installed on the upper housing 433 so as to reduce the influence of the vibration of the fan on the air outlet hood 41. The upper housing 433 and the lower housing 432 can be connected by fasteners. Exemplarily, the upper end of the fourth guiding protrusion 4328 of the lower housing 432 can be connected with a lower housing plate 4329, and the lower housing plate 4329 can extend towards the outside of the impeller 4311. At least part of the lower end of the upper housing plate 4331 can abut against the upper end of the lower housing plate 4329 and can be connected together by fasteners.

[0161] In addition, a lower housing flange 43291 can be connected to the lower housing plate 4329, the lower housing flange 43291 can extend upwards, and a preset gap can be provided between the lower housing flange 43291 and the fourth guiding protrusion 4328. The side wall of the upper housing plate 4331 can be embedded in the lower housing flange 43291 so as to limit the movement of the upper housing plate 4331. In addition, an upper housing flange 43311 can be connected to the outer periphery of the upper housing plate 4331 to enhance the structural strength of the upper housing plate 4331. The upper housing flange 43311 can extend upwards and be embedded in the lower housing flange 43291.

[0162] Furthermore, a fastening protrusion 43292 can be connected to the lower end of the lower housing plate 4329, and the fastener can pass through the upper housing plate 4331 and the lower housing plate 4329 in sequence and be threadedly connected to the fastening protrusion 43292.

[0163] Optionally, as Figure 11As shown, an upper guiding recess 4332 may be provided on the upper cover plate 4331. The upper guiding recess 4332 may extend upward to increase the air outlet height and area of the first air outlet hole 43281 and / or the second air outlet hole 43283. Exemplarily, the upper guiding recess 4332 may include a first end and a second end. Along the direction of rotation of the impeller 4311, the height of the upper guiding recess 4332 gradually increases. That is, the height of the second end of the upper guiding recess 4332 is higher than the height of the first end of the upper guiding recess 4332. The second end of the upper guiding recess 4332 may be open and communicate with the first air outlet hole 43281 and / or the second air outlet hole 43283. Each of the first air outlet holes 43281 and / or the second air outlet holes 43283 is connected to a corresponding upper guiding recess 4332.

[0164] It can be understood that when the upper guiding recess 4332 is not provided, the upper cover plate 4331, the third guiding protrusion 4327, and the fourth guiding protrusion 4328 define a third guiding channel 423. The height of the first air outlet hole 43281 and / or the second air outlet hole 43283 must be lower than the height between the upper cover plate 4331 and the third guiding protrusion 4327. When the upper guiding recess 4332 is provided, the gas can be guided upward, and the height of the first air outlet hole 43281 and / or the second air outlet hole 43283 is also increased.

[0165] Optionally, Figure 14 shown Figure 10 partial cross-sectional view at N-N, as Figure 10 、 Figure 11 and Figure 14 As shown, a connecting gasket 66 may be provided between the blower and the upper cover 433. The connecting gasket 66 may be made of a rubber material to have a vibration damping effect. When assembling the blower, fasteners may be used to sequentially pass through the upper cover 433 and the connecting gasket 66 to connect with the blower.

[0166] Optionally, the upper cover 433 may be provided with an upper recess extending upward, and at least part of the blower may be embedded in the upper recess to position the blower through the upper recess.

[0167] Optionally, a positioning groove may be provided at the upper end of the upper cover 433, and a positioning flange 661 may be connected to the connecting gasket 66. The positioning flange 661 may extend toward the upper cover 433 and extend into the positioning groove. The outer side wall of the positioning flange 661 may abut against the groove wall of the positioning groove.

[0168] It is worth noting that the difficulty of determining the relative position of the blower relative to the upper cover 433 can be reduced by designing the shape of the positioning groove. Exemplarily, the positioning groove may be an asymmetric shape, or the positioning groove may be a symmetric shape, such as the positioning groove may be in a "cross" shape.

[0169] Exemplarily, asFigure 14 As shown, a reinforcing post 662 may be connected to the connecting gasket 66, and at least two through holes may be provided on the upper cover 433. The reinforcing post 662 may include a first end and a second end, and the cross-section of the first end of the reinforcing post 662 may be larger than the cross-section of the second end of the reinforcing post 662. The first end of the reinforcing post 662 may be located above the upper cover 433, the lower end surface of the first end of the reinforcing post 662 may abut against the outer periphery of the through hole, and the second end of the reinforcing post 662 may pass through the through hole of the upper cover 433 and be connected to the connecting gasket 66. The fastener may pass through the reinforcing post 662, the connecting gasket 66 and be connected to the fan. In this way, through the connecting gasket 66 and the reinforcing post 662, the fan and the upper cover 433 are isolated. The reinforcing post 662 and the connecting gasket 66 may be made of rubber material to weaken the influence of the fan on the upper cover 433.

[0170] Optionally, Figure 15 A perspective view showing a part of the upper cover 433 is shown, as Figure 1 , Figure 11 and Figure 15 shown. Since the upper cover 433 is used to connect the fan, the upper cover 433 may be provided with a reinforcing structure to enhance the structural strength of the upper cover 433. Exemplarily, a first reinforcing protrusion 4343 is provided around the outer periphery of the grooves and holes (such as through holes and positioning grooves) on the upper cover 433 to improve the structural strength of the positions of the grooves and holes. The positioning grooves or multiple through holes provided on the upper cover 433 may be concentrated in the middle position of the upper cover 433. Adjacent two first reinforcing protrusions 4343 may be connected by a fourth reinforcing protrusion 4349, and the fourth reinforcing protrusion 4349 may be arranged in an arc shape.

[0171] Optionally, a second reinforcing protrusion 4344 arranged in a ring shape may be connected to the upper cover 433. The multiple through holes on the upper cover 433 may be located inside the second reinforcing protrusion 4344 to further improve the structural strength of the positions of the grooves and holes.

[0172] Optionally, a first radial protrusion 4345 is connected between the outer side of the first reinforcing protrusion 4343 and the inner side of the second reinforcing protrusion 4344. The first radial protrusion 4345 can not only connect the first reinforcing protrusion 4343 and the second reinforcing protrusion 4344 together to improve the integrity of the upper cover 433. The first radial protrusion 4345 can also be used to support the first reinforcing protrusion 4343 and the second reinforcing protrusion 4344.

[0173] Optionally, a third reinforcing protrusion 4346 arranged in a ring shape may be provided on the outer side of the upper depression provided on the upper cover 433 to improve the structural strength of the position of the upper depression. In addition, the through hole or the mounting groove on the upper housing 1811 may be provided on the upper depression to facilitate the connection between the upper cover 433 and the fan.

[0174] Optionally, a second radial protrusion 4347 is provided between the third reinforcing protrusion 4346 and the second reinforcing protrusion 4344. Among them, the first radial protrusion 4345 and the second radial protrusion 4347 can be evenly distributed circumferentially on the second reinforcing protrusion 4344 and the third reinforcing protrusion 4346 respectively, and the second radial protrusion 4347 and the first radial protrusion 4345 can be arranged in a staggered manner. The second radial protrusion 4347 can extend radially toward the second reinforcing protrusion 4344. It can be understood that the second radial protrusion 4347 can also connect the first reinforcing protrusion 4343 and the second reinforcing protrusion 4344 together to further improve the structural strength of the upper cover 433.

[0175] Optionally, a third radial protrusion 4348 is further provided on the upper cover 433. The third radial protrusion 4348 can be connected to the third reinforcing protrusion 4346 and extend toward the outer periphery of the outer cover to improve the overall structural strength of the upper cover 433.

[0176] Optionally, Figure 16 shown Figure 11 in the enlarged view of F, as Figure 11 and Figure 16 shown, a capacitor starter 4334 can be provided on the upper cover 433 to help start the fan. Exemplarily, a placement cavity is provided on the upper cover 433 to limit and fix the capacitor starter 4334. The placement cavity can be defined by a plurality of placement protrusions 4335 connected to the upper cover 433. At least two placement protrusions 4335 are made of an elastic material to abut against the side wall of the capacitor starter 4334, thereby fixing the capacitor starter 4334. The height of the placement protrusion 4335 can be lower than the height of the capacitor starter 4334 to facilitate installation or maintenance by the operator.

[0177] In addition, a clamping block 4336 can be connected to the upper end of at least two relatively arranged placement protrusions 4335. The clamping block 4336 can extend toward the capacitor starter 4334 to limit the movement of the capacitor starter 4334 in the height direction. Opposite ends of the capacitor starter 4334 can be clamped to the two clamping blocks 4336. Exemplarily, the end of the clamping block 4336 facing away from the placement protrusion 4335 can have a guiding inclined surface 1613. From the outer periphery of the capacitor starter 4334 to the axis direction of the capacitor starter 4334, the guiding inclined surface 1613 can gradually extend downward to guide the placement of the capacitor starter 4334. It should be noted that the placement protrusion 4335 or the clamping block 4336 connected with the clamping block 4336 can have an elastic displacement along the extending direction of the clamping block 4336.

[0178] It should be noted that, as Figure 1 and Figure 11As shown, a plurality of annular reinforcing protrusions may be provided on the upper cover body 433, and adjacent two reinforcing protrusions may be connected by radial protrusions.

[0179] Optionally, as Figure 15 shown, wire-passing grooves may be provided on the radial protrusions and the annular reinforcing protrusions for the wires for power supply and / or communication to pass through. A wire-fixing protrusion 4337 may also be provided on the upper cover body 433 for fixing the wires. The wire-fixing protrusions 4337 may be arranged in pairs. The wire-fixing protrusion 4337 may include a first end and a second end. The first end of the wire-fixing protrusion 4337 may be connected to the upper cover body 433, the second end of the fixing protrusion may extend upward, and the second end of the wire-fixing protrusion 4337 may be bent downward relative to the first end of the wire-fixing protrusion 4337. The two opposite surfaces of the second ends of the two wire-fixing protrusions 4337 are inclined, specifically, inclined downward gradually from the outside to the inside of the fixing protrusion, so as to guide the wires for power supply and / or communication to be inserted between the two wire-fixing protrusions 4337 from top to bottom.

[0180] In summary, in the case of lateral air intake, a possible implementation of the gas flow process is as follows: the dusty gas from the outside is guided by the centrifugal fan 431, enters the primary filter assembly 31 from the side, is preliminarily filtered by the primary filter assembly 31, then enters the water tank 11 from the air inlet of the water tank 11, contacts the washing liquid thrown out in the water tank 11, and thus the purified gas is obtained. The purified gas flows out of the water tank 11 from the upper end of the water tank 11, enters the impeller 4311 of the centrifugal fan 431 to turn, and comes out from the first air outlet hole 43281 and / or the second air outlet hole 43283 on the air outlet cover 41.
