The air inlet 12 and the air outlet 13 are both communicated with the mounting cavity 11.
The filtering mechanism 2, the cleaning spray head 3, the flow guide piece 4 and the water receiving disc 5 are all installed in the installation cavity 11.
The filter mechanism 2 divides the installation cavity 11 into two chambers in the housing, and the two chambers are respectively communicated with the air inlet 12 and the air outlet 13, so that the air entering from the air inlet 12 can be discharged from the air outlet 13 after being filtered by the filter mechanism 2.
The filtering mechanism 2 comprises a mounting frame 21 and a filtering net 22, wherein the mounting frame 21 is of a cylindrical structure and is vertically arranged in the machine shell 1 along the axial lead direction. The filter screen 22 is also cylindrical, and is sleeved on the mounting frame 21 to form a wrapping structure, so that air entering from the air inlet 12 enters from the outer side of the filter screen 22 to the inner side and is discharged from the air outlet 13.
Wherein, the filter screen 22 is provided with at least two layers along the radial direction to form a graded filter structure.
A coarse filter (not shown) is arranged at the air inlet 12 of the casing 1 for blocking large particles such as hair at the air inlet 12 to prevent them from entering and blocking the filter screen 22 to affect the filtering effect.
The cleaning nozzle 3 is arranged on the axis of the mounting frame 21 and is arranged at the bottom of the filtering mechanism 2, and a liquid inlet pipe communicated with the outside is arranged on the side wall of the cleaning nozzle.
The cleaning spray head 3 is arranged along the vertical direction, the spray nozzle faces upwards, the flow guide piece 4 is arranged above the spray nozzle, the end face of one end of the flow guide piece facing the spray nozzle is circular, and the end face is a conical circumferential surface 44 with the center protruding towards the direction of the spray nozzle. The cleaning liquid sprayed from the nozzle impacts the conical circumferential surface 44, a water curtain structure of 360 degrees is formed under the guiding action of the conical circumferential surface 44, and then the formed water curtain has enough water pressure to impact the filter screen 22 and wash away the dirt on the filter screen 22 through the arrangement of the water pressure at the nozzle.
The water pressure at the nozzle is at least 0.6MPA, wherein, during the downward movement of the guide, the gap between the guide and the nozzle is reduced, and the generated water pressure is correspondingly increased, so that the basic water pressure is set when the guide 4 is lifted to the top, so as to ensure that the formed water curtain can impact the top of the filter screen 22.
The center of the conical circumferential surface 44 is integrally provided with a driving rod 41, the driving rod 41 extends into the cleaning nozzle 3 from the nozzle, the end part of the driving rod 41 penetrates through the cleaning nozzle 3 and penetrates out of the cleaning nozzle 3, and the cross section of the driving rod 41 is in a regular quadrilateral shape, so that the driving rod 41 is axially positioned and inserted on the cleaning nozzle 3. The driving rod 41 is sealed with a sealing member between the driving rod 41 and the through hole of the cleaning head 3, and keeps the driving rod 41 movable on the cleaning head 3.
A screw elevating mechanism 42 is connected to an end of the driving rod 41, and a screw of the screw elevating mechanism 42 is integrally provided at the end of the driving rod 41. The worm of the spiral elevating mechanism 42 is connected with a rotating shaft of a driving motor 43, and the worm is integrally provided with the rotating shaft in the embodiment. The driving motor 43 drives the rotating shaft to rotate, then drives the turbine in the spiral lifting mechanism 42 to rotate, and the turbine drives the screw rod to move up and down after rotating, so as to drive the guide piece to ascend and descend in the vertical direction.
The water pan 5 is arranged at the outer side of the bottom end of the filtering mechanism 2, and is shown in the attached drawing 2, the water pan 5 is in a ring shape, the inner circle of the ring shape is connected to the filtering mechanism 2, and the outer circle of the ring shape is connected to the inner wall of the casing 1. The circular water pan 5 is provided with a diversion canal 51, and the diversion canal 51 is formed by the downward sinking of the two edges of the inner circle and the outer circle to the space between the two edges.
As shown in fig. 3, the diversion canal 51 is disposed obliquely along the circumferential direction, and a recessed depression 52 is formed on the water pan 5, and the depth of the depression 52 is smaller than that of the diversion canal 51.
An opening is arranged at the depression 52, the opening is connected with a drain pipe 9, and the drain pipe 9 is a siphon pipe.
As shown in fig. 1, a plurality of ultraviolet germicidal lamps 6 are fixed to the inner wall of the housing 1.
The working principle is as follows: in normal use, air enters the housing through the air inlet 12, is filtered by the filter screen 22 and then exits through the air outlet 13.
When the filter screen 22 needs to be cleaned after being used for a period of time, clean water or configured cleaning solution is introduced from the water inlet pipe 8 and then is sprayed out from the cleaning spray head 3. When the water flow is sprayed out, the water flow is sprayed onto the flow guide part 4 under the action of water pressure, and after the blocking and the guiding of the conical circumferential surface 44, a water curtain of 360 degrees is formed, and the water curtain impacts the filter screen 22 under the action of the water pressure.
When the cleaning nozzle 3 is started, the driving motor 43 rotates under the control of a circuit or a chip, the driving motor 43 rotates in a mode of forward rotation and reverse rotation which are repeated continuously, the forward rotation time and the reverse rotation time are the same, and the guide piece is slowly lifted and lowered in a reciprocating mode through rotation at a slow speed, so that the formed water curtain is lifted and lowered in a reciprocating mode, and the whole filter screen 22 is cleaned in an impact mode.
Example 2: as shown in fig. 4, the difference from embodiment 1 is that the guide member 4 is controlled by a driving cylinder 7 to reciprocate along the axial line of the mounting frame 21.
Example 3: as shown in fig. 5 and 6, the difference from embodiment 1 is that the angle between the radial direction and the axial line of the circumferential surface 44 of the guide member is gradually changed.
The guide member 4 is rotatably connected to the driving rod 41, and a plurality of spiral grooves 45 are formed on a circumferential surface 44 of the guide member 4.
Through the gradual change setting, there is the difference in height in the position that makes the water curtain that forms spraying on filter screen 22, rethread helicla flute 45 and the setting of rotation connection for under the effect of rivers, the guide can take place to rotate, thereby can make the guide when same position, wash the area and become one section torus from a ring line, cover bigger area, thereby make the guide can wash filter screen 22 of bigger area at littleer moving distance ability.
Example 4: the difference from embodiment 2 is that the angle between each radial direction of the circumferential surface 44 of the guide and the axial line is gradually changed.
The guide member 4 is rotatably connected to the driving rod 41, and a plurality of spiral grooves 45 are formed on a circumferential surface 44 of the guide member 4.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all the embodiments are protected by patent laws within the scope of the present invention.
