The transmission connecting rod passes through the lower connecting shell and the upper base plate and is connected to the bottom end of the air inlet baffle. The air inlet baffles are movably connected through elastic connecting strips. The top end of the lower connecting shell is slidingly connected to the bottom end of the air inlet baffle, and the bottom end of the upper connecting shell is slidingly connected to the top end of the air inlet baffle. The bottom end of the transmission connecting rod is connected to a vibration rod, and a vibration pull rod is installed at the bottom end of the vibration rod.

There are several strip holes on the air inlet baffle, which are used to ensure air intake while blocking large particles of dust filtered by the primary filter. The lower base plate and the upper base plate are both provided with holes that match the lower connecting shell. The connecting plate, the air inlet baffle and the primary filter form a chamber, and the bottom of the chamber is connected to the dust box through the lower connecting shell.

Air enters from the strip holes on the air inlet baffle and flows into the primary filter.

A slide rail corresponding to the slide groove of the motor support is provided on one side of the connecting piece. A driving module is integrated in the motor support to drive the driving motor to move along the slide rail so that the motor gear engages with the propulsion gear or the driving gear for transmission.

After that, the drive motor is started, and the output shaft of the drive motor drives the motor gear to rotate. The motor gear causes the transmission rack to slide forward through the propulsion gear, and the transmission rack slides between the upper base plate and the lower base plate, thereby driving the guide device to extend outward. When the guide device is fully extended, the control system starts the fan.

An electromagnet is installed on the lock frame, an oblique push block is slidably installed on the lock frame, an oblique pressure block is movably installed on the lock frame, the oblique pressure block is movably connected to the oblique push block, a second return spring is installed at the bottom end of the oblique pressure block, and a downward pressing block is installed on the oblique pressure block through a push block connecting rod.

The outer frame is connected to the bottom end of the outer casing, the upper base plate and the column by elastic telescopic parts on all sides. A swing blade slide rod is installed on the outer frame.

Swing blade sliders are installed on both sides of the upper swing blade, and swing blade sliders are installed on both sides of the lower swing blade. The swing blade slide rod is slidably connected to the swing blade sliders. The upper connecting rod is slidably connected to the outer frame through the top slider and the upper fixed slider, and the lower connecting rod is slidably connected to the outer frame through the upper fixed slider and the lower fixed slider. The guide rotating rod passes through the upper fixed slider and the lower fixed slider and is installed with an upper sliding roller, a lower sliding roller and a guide gear. The upper connecting rod is slidably connected to the upper sliding roller, and the lower connecting rod is slidably connected to the lower sliding roller.

Formaldehyde concentration detectors are provided on the upper swing blade group and the lower swing blade group for feeding back the formaldehyde concentration entering the upper swing blade group and the lower swing blade group to the control system.

The fan drives the air to enter from the upper and lower blades. When the air flows through the formaldehyde concentration detection device, the formaldehyde concentration detection device transmits the formaldehyde concentrations of the upper and lower blade groups in four directions to the control system respectively. The control system identifies the direction with the most concentrated formaldehyde by analyzing the formaldehyde concentration values in the four directions. After that, the control system starts the intelligent base, and the intelligent base drives the entire air purification device to move in the direction with the most concentrated formaldehyde through the tires at the bottom; at the same time, the control system adjusts the extension length of the transmission rack according to the total formaldehyde content. When the formaldehyde concentration is low, the transmission rack is controlled to drive the guide device to retract, so that the suction radius of the guide device is reduced. When the formaldehyde concentration is high, the guide device is kept fully extended.

An upper sliding groove is provided on the upper sliding roller, and the upper sliding groove includes a first upper inclined groove, and a lower transverse groove and an upper transverse groove are respectively provided at both ends of the first upper inclined groove; a lower sliding groove is provided on the lower sliding roller, and the lower sliding groove includes a second upper inclined groove, and a first lower inclined groove and a second lower inclined groove are respectively provided at both ends of the second upper inclined groove.

After the position of the diversion device is adjusted, the control system continues to analyze the formaldehyde concentrations of the upper and lower swing leaf groups in all directions. When the formaldehyde content of the upper swing leaf group in one direction is significantly higher, the control system supplies power to the electromagnet. After the electromagnet is energized, a strong magnetic field is generated. The lock head is attracted by the electromagnetic field and slides toward the electromagnet on the positioning slide bar. When the lock head slides, it pushes the oblique push block to slide in the lock frame, and the oblique push block pushes the oblique pressure block. The oblique pressure block converts the horizontal thrust into downward pressure, thereby overcoming the elastic force of the second reset spring, and driving the downward pressure block to be stuck in the groove of the lower bottom plate slide rail through the push block connecting rod. Since the lock head disconnects the locking of the tooth chain and the transmission rack is fixed as a whole and cannot move, the tooth chain can rotate on the transmission roller at this time, and the rack rotates The guide gear is driven to rotate, and the guide gear drives the upper sliding roller and the lower sliding roller to rotate through the guide rotating rod. The control system controls the driving motor to rotate, so that the upper sliding roller and the lower sliding roller are rotated to the lowest position of the first upper inclined slot and the lowest position of the second upper inclined slot respectively. At this time, the upper sliding roller drives the upper connecting rod to move downward, and the swing blade rotating rod follows the upper connecting rod downward. The swing blade slider slides on the swing blade slider, so that the upper swing blade group opens upward. Since the slotting paths of the first upper inclined slot and the second upper inclined slot are consistent, at this time, the lower swing blade group also opens upward, so that the upper air with high formaldehyde content is quickly inhaled. At the same time, the control system turns on the electric telescopic rod to raise the guide device as a whole, so as to further absorb the upper air with high formaldehyde content.

When the control system detects that the formaldehyde concentration of the lower swing blade group is significantly higher than that of the upper swing blade group, the control system causes the upper sliding roller and the lower sliding roller to rotate to the highest position of the first upper inclined slot and the highest position of the second upper inclined slot respectively. According to the above principle, at this time, the openings of the upper swing blade group and the lower swing blade group are both facing downward, so that the air with higher formaldehyde content in the lower part is quickly sucked in. At the same time, the control system causes the guide device to descend as a whole to further absorb the air with higher formaldehyde content in the lower part.

When the control system detects that the formaldehyde concentrations of the upper and lower swing blade groups are both high, the control system rotates the upper sliding roller and the lower sliding roller to the highest points of the lower horizontal groove and the first lower inclined groove respectively. At this time, the upper swing blade group opening faces upward, the lower swing blade opening faces downward, and the speed at which the guide device inhales air reaches the maximum; when the control system detects that the formaldehyde concentrations of the upper and lower swing blade groups are both low, the control system rotates the upper sliding roller and the lower sliding roller to the lowest points of the upper horizontal groove and the second lower inclined groove respectively. At this time, the upper swing blade group opening faces downward, the lower swing blade opening faces upward, and the speed at which the guide device inhales air is the minimum.

When the air passes through the photocatalyst layer upward from the ionization network, the control system turns on the ultraviolet light strip, and the ultraviolet light strip irradiates the photocatalyst layer to produce a photoelectrochemical reaction, decomposing formaldehyde into water and carbon dioxide for discharge. When there is a lot of dust on the photocatalyst layer, the control system turns on the corresponding two motor supports, and the motor supports drive the drive motor to move, so that the motor gear and the drive gear mesh and transmit, and the control system causes the two drive motors to rotate in the opposite direction, and the drive gear drives the drive rod to rotate, and the drive rod drives the screw rod to rotate through the bevel gear set, and the screw rod drives the brush wheel to move horizontally through the bearing joint, and the rotating gears at both ends of the brush wheel mesh with the rotating rack for transmission, and the rotating gear rotates along the rack under the action of horizontal force, thereby driving the brush wheel to rotate on the bearing in the bearing joint, and the horizontally rotating brush wheel cleans the upper and lower photocatalyst layers, and can clean the dust attached to the ultraviolet light strip together, and the cleaned dust falls into the bottom dust box, and the dust box is taken out from the bottom of the lower bottom plate, and the collected dust is poured into the trash can, so as to achieve the purpose of self-cleaning of the overall air purification device.

The bearing joint 53 has a built-in bearing, and a plurality of brush strips are installed on the brush wheel 54.

The working principle of the present invention is as follows: the control system starts the motor support 94, the motor support 94 drives the drive motor 93 to move, so that the motor gear 91 and the propulsion gear 96 are meshed for transmission, and then the drive motor 93 is started, the output shaft of the drive motor 93 drives the motor gear 91 to rotate, the motor gear 91 causes the transmission rack 97 to slide forward through the propulsion gear 96, and the transmission rack 97 slides between the upper base plate 75 and the lower base plate 76, thereby driving the guide device 1 to extend outward, and when the guide device 1 is fully extended, the control system starts the fan 6.

The fan 6 drives the air to enter from the upper swing blades 12 and the lower swing blades 13. When the air flows through the formaldehyde concentration detection device, the formaldehyde concentration detection device transmits the formaldehyde concentrations of the upper swing blades 12 and the lower swing blades 13 in four directions to the control system respectively. The control system identifies the direction in which the formaldehyde is most concentrated by analyzing the formaldehyde concentration values in the four directions. After that, the control system starts the intelligent base 2. The intelligent base 2 drives the entire air purification device to move in the direction in which the formaldehyde is most concentrated through the tires at the bottom; at the same time, the control system adjusts the telescopic length of the transmission rack 97 according to the total formaldehyde content. When the formaldehyde concentration is small, the transmission rack 97 is controlled to drive the guide device 1 to retract, so that the suction radius of the guide device 1 is reduced. When the formaldehyde concentration is large, the guide device 1 is kept fully extended.

After the position of the guide device 1 is adjusted, the control system continues to analyze the formaldehyde concentrations of the upper swing leaf group 12 and the lower swing leaf group 13 in each direction. When the formaldehyde content of the upper swing leaf group 12 in one direction is significantly higher, the control system supplies power to the electromagnet 9713. After the electromagnet 9713 is energized, a strong magnetic field is generated. The lock head 975 is attracted by the electromagnetic field and slides toward the electromagnet 9713 on the positioning slide bar 971. When the lock head 975 slides, it pushes the oblique push block 979 to slide in the lock frame 978. The oblique push block 979 pushes the oblique pressure block 9710. The oblique pressure block 9710 converts the horizontal thrust into downward pressure, thereby overcoming the elastic force of the second reset spring 977, and driving the downward pressure block 9712 to be stuck in the card groove of the slide rail of the lower bottom plate 76 through the push block connecting rod 9711. Since the lock head 975 disconnects the locking of the tooth chain 972, and the transmission rack 97 is fixed as a whole and cannot move, at this time, the tooth chain 972 can be on the transmission roller 9 73 rotates, the rack rotates to drive the guide gear 110 to rotate, and the guide gear 110 drives the upper sliding roller 14 and the lower sliding roller 18 to rotate through the guide rotating rod 19, and the control system controls the driving motor 93 to rotate, so that the upper sliding roller 14 and the lower sliding roller 18 rotate to the lowest position of the first upper inclined slot 142 and the lowest position of the second upper inclined slot 182 respectively. At this time, the upper sliding roller 14 drives the upper connecting rod 114 to move downward, and the swing blade rotating rod 113 follows the upper connecting rod 114 downward, and the swing blade slider 111 slides on the swing blade slider 112, so that the upper swing blade 12 group of openings face upward. Since the slotting paths of the first upper inclined slot 142 and the second upper inclined slot 182 are consistent, at this time, the lower swing blade 13 group of openings also face upward, so that the upper air with high formaldehyde content is quickly inhaled. At the same time, the control system turns on the electric telescopic rod 78 to raise the guide device 1 as a whole to further absorb the upper air with high formaldehyde content;

When the control system detects that the formaldehyde concentration of the lower swing leaf group 13 is significantly higher than that of the upper swing leaf group 12, the control system causes the upper sliding roller 14 and the lower sliding roller 18 to rotate to the highest position of the first upper inclined slot 142 and the highest position of the second upper inclined slot 182 respectively. According to the above principle, at this time, the openings of the upper swing leaf group 12 and the lower swing leaf group 13 are both facing downward, so that the air with higher formaldehyde content in the lower part is quickly sucked in. At the same time, the control system causes the guide device 1 to descend as a whole to further absorb the air with higher formaldehyde content in the lower part.

When the control system detects that the formaldehyde concentrations of the upper and lower swing leaf groups 12 and 13 are both high, the control system rotates the upper sliding roller 14 and the lower sliding roller 18 to the highest points of the lower transverse groove 141 and the first lower inclined groove 181 respectively. At this time, the openings of the upper and lower swing leaf groups 12 face upward, and the openings of the lower and lower swing leaf groups 13 face downward, and the speed at which the air is inhaled by the guide device 1 reaches the maximum; when the control system detects that the formaldehyde concentrations of the upper and lower swing leaf groups 12 and 13 are both low, the control system rotates the upper sliding roller 14 and the lower sliding roller 18 to the lowest points of the upper transverse groove 143 and the second lower inclined groove 183 respectively. At this time, the openings of the upper and lower swing leaf groups 12 face downward, and the openings of the lower and lower swing leaf groups 13 face upward, and the speed at which the air is inhaled by the guide device 1 is the minimum.

The air enters from the strip holes on the air inlet baffle 32 and flows into the primary filter 31. The large dust particles in the air are blocked by the primary filter 31. Some of the dust remains in the chamber formed by the connecting plate 34, the air inlet baffle 32 and the primary filter 31. After that, the dust gradually settles and slides from the lower connecting shell 79 into the dust box 8. The other part of the dust adheres to the primary filter 31. The driving device 9 drives the vibration gear 36 to rotate when it is extended or rotated. The rotation of the vibration gear 36 drives the vibration pull rod 37 to move to one side. When the vibration gear 36 continues to rotate, the vibration pull rod 37 The pulling teeth on the upper part will disengage from the tooth grooves of the vibration gear 36, and then the vibration spring 38 drives the vibration pull rod 37 to retract and reset. The reset vibration pull rod 37 meshes with the vibration gear 36 again, and the cycle is repeated. During this process, the vibration pull rod 37 drives the air inlet baffle 32 to slide back and forth between the upper connecting shell 77 and the lower connecting shell 79 through the vibration rod 35 and the transmission connecting rod 39, and the air inlet baffle 32 drives the primary filter 31 to vibrate back and forth through the connecting plate 34, and the primary filter screens 31 collide with each other due to their close positions, so that the dust on the primary filter screen 31 is shaken off to the dust collecting box.

When air flows from the primary filter 31 to the ionizing net 41 , the control system energizes the ionizing net 41 . After the needles on the ionizing net 41 are energized, an electromagnetic field is generated, which adsorbs fine dust on the ionizing net 41 . When there is a lot of dust on the ionizing net 41, the control system starts the corresponding motor support 94, and the motor support 94 drives the drive motor 93 to move, so that the motor gear 91 and the drive gear 95 are meshed and transmitted, and the drive gear 95 drives the drive rod 92 to rotate, and the drive rod 92 drives the first rotating rod 42 to rotate through the bevel gear set, and the eccentric block 47 on the first rotating rod 42 causes the eccentric connecting rod 48 to reciprocate, and the eccentric connecting rod 48 drives the ionizing net 41 to slide back and forth in the inner casing 73 through the ionizing connecting block 49. The sliding of the ionizing net 41 drives the second rotating rod 43 to slide together, and the knocking gears 46 on both sides of the second rotating rod 43 are meshed and transmitted with the knocking rack 45, so that the second rotating rod 43 rotates, and the rotation of the second rotating rod 43 drives the knocking block 44 to repeatedly knock the ionizing net 41. Under the combined action of up and down knocking and back and forth swinging, the dust on the upper part of the ionizing net 41 is shaken off and finally falls into the dust collecting box 8 at the bottom.

When the air passes upward from the ionization network 41 through the photocatalyst layer 51 , the control system turns on the ultraviolet light strip 57 , and the ultraviolet light strip 57 irradiates the photocatalyst layer 51 to generate a photoelectrochemical reaction, thereby decomposing the formaldehyde into water and carbon dioxide for discharge. When there is a lot of dust on the photocatalyst layer 51, the control system turns on the corresponding two motor supports 94, and the motor supports 94 drive the drive motor 93 to move, so that the motor gear 91 and the drive gear 95 are meshed and transmitted. The control system makes the two drive motors 93 rotate in opposite directions, and the drive gear 95 drives the drive rod 92 to rotate. The drive rod 92 drives the screw rod 52 to rotate through the bevel gear set, and the screw rod 52 drives the brush wheel 54 to move horizontally through the bearing joint 53. The rotating gears 55 at both ends of the brush wheel 54 are meshed and transmitted with the rotating rack 56. The rotating gear 55 rotates along the rack under the action of horizontal force, thereby driving the brush wheel 54 to rotate on the bearing in the bearing joint 53. The horizontally rotating brush wheel 54 cleans the upper and lower photocatalyst layers 51, and can clean the dust attached to the ultraviolet light strip 57 together. The cleaned dust falls into the bottom dust box 8, and the dust box 8 is taken out from the bottom end of the lower base plate 76, and the collected dust is poured into the trash can, thereby achieving the purpose of self-cleaning of the overall air purification device.
