Description

Technical Field

[0001] The invention belongs to the technical field of indoor air purifiers, and in particular relates to an indoor air purifier based on formaldehyde removal gel. Background Art

[0002] Indoor formaldehyde mainly comes from artificial boards such as plywood, joinery formwork, medium-density fiberboard, wood core board used in decoration, decoration materials such as white latex, foam plastic, paint and coating containing formaldehyde, and interior decorative textiles such as wall coverings, wallpaper, chemical fiber carpets and fabrics.

[0003] Chlorine dioxide is a water-soluble strong oxidant with high efficiency and broad-spectrum bactericidal ability. It can quickly oxidize and decompose bacteria, viruses, amino acids in proteins, and many reducing substances. This makes chlorine dioxide widely used as a disinfectant and sterilizer in food, hygiene, and epidemic prevention, as well as a new type of air purifier and freshener. Chlorine dioxide also has a strong killing effect on indoor formaldehyde.

[0004] In the prior art, chlorine dioxide gel is generally placed directly in the indoor environment, and chlorine dioxide gas is generated through the self-volatilization of chlorine dioxide gel, and the volatilized chlorine dioxide gas escapes into the indoor environment, thereby achieving indoor formaldehyde purification. However, the efficiency of chlorine dioxide gas generated by the self-volatilization of chlorine dioxide gel is low, and the generated chlorine dioxide gas has a poor purification effect on formaldehyde in an open indoor environment.

If the first through-hole is aligned with the second through-hole, the air flow passes through the first through-hole on the gel dissipation cylinder and the second through-hole on the gel filling cylinder in sequence to enter the interior of the gel filling cylinder, and then passes through the second through-hole on the gel filling cylinder, the first through-hole on the gel dissipation cylinder in sequence to enter the interior of the gel filling cylinder. The air enters the guide channel through the hole and the first conducting port, and then enters the inner cavity of the annular partition plate through the second conducting port, thereby the chlorine dioxide gas volatilized in each gel filling tube can be purged and transported to the closed inner cavity of the annular partition plate through the dust-filtering air flow, and the indoor air and chlorine dioxide gas are fully contacted in the inner cavity of the annular partition plate, so the purification effect of formaldehyde in the indoor air can be greatly improved, and the air flow through the gel filling tube can accelerate the volatilization of the gel, thereby improving the purification efficiency of formaldehyde in the indoor air in the inner cavity of the annular partition plate.

[0015] 2. When the air pressure in the inner cavity of the annular partition plate approaches a set pressure threshold, the present invention stops delivering the mixed air flow into the inner cavity of the annular partition plate and starts to extract the mixed gas therein, and at the same time controls each radial extension rod to rotate in the opposite direction at the same time through the purification control motor, and under the elastic restoring force of the elastic element, each transmission tooth plate slides in the opposite direction along the corresponding guide groove and resets until the first through-hole on the gel dissipation cylinder returns to the initial position, that is, the first through-hole on the gel dissipation cylinder is in a cross-staggered position relationship with the second through-hole on the gel filling cylinder again, and then the mixed gas in the inner cavity of the annular partition plate can be discharged to realize the backwashing of each dust filter.

After being filtered, the indoor air enters the vertical installation cylinder 202 through the air inlet 210, and the air entering the vertical installation cylinder 202 enters the space below the partition plate 208 along the first arc-shaped vent 209. If at this time the first through-hole 302 is aligned with the second through-hole 401 (the first through-hole 302 is aligned with the second through-hole 401), the air inlet 210 will enter the vertical installation cylinder 202. The air flows through the first through-hole 302 on the gel dissipation tube 301 and the second through-hole 401 on the gel filling tube 4 in turn, enters the interior of the gel filling tube 4, and then flows through the second through-hole 401 on the gel filling tube 4, the first through-hole 302 on the gel dissipation tube 301 and the first through-hole 204 in turn, enters the guide channel 203, and then enters the inner cavity of the annular partition plate 201 through the second through-hole 205.

The bottom of the air filter cartridge 303 is mounted on the inner wall of the vertically mounted cylinder 202, and is fitted on the top of the partition plate 208. A second arc-shaped vent is provided at the bottom of the air filter cartridge 303. The indoor air filtered by the dust filter net 5 enters the air filter cartridge 303 through the dust filter strip holes 305, and then passes through the second arc-shaped vent at the bottom of the air filter cartridge 303 and the first arc-shaped vent 209 on the partition plate 208 in sequence to enter the space below the partition plate 208. A first support rod rotatably connected to the partition plate 208 is fixed at the bottom of the air filter cartridge 303, and a limiting member is fixedly provided on the side surface around the first support rod. A limiting groove that matches the gap with the limiting member is provided on the inner wall of the top opening of the gel dissipation cartridge 301. This structural design can ensure that the gel dissipation cartridge 301 rotates synchronously with the air filter cartridge 303.

[0038] In this embodiment of the present invention, a second support rod rotatably connected to the vertical installation cylinder 202 is fixed on the top of the air filter cylinder 303, a transmission gear 306 is fixedly installed on the top of the second support rod, a guide groove 211 corresponding to the vertical installation cylinder 202 is arranged in an annular array on the top of the purification control box 207, a transmission tooth plate 307 slidably connected to the corresponding guide groove 211 is arranged on the top of the purification control box 207, the transmission tooth plate 307 is meshed with the corresponding transmission gear 306, an oblique force plate 308 is fixedly arranged on one end of the transmission tooth plate 307, and the top of the purification control box 207 is fixed A first mounting plate 309 is provided, and a second mounting plate 310 is fixedly provided on one side of the transmission gear plate 307, and the first mounting plate 309 and the second mounting plate 310 are connected by an elastic element 311; a supporting frame 212 is fixedly provided on the top of the purification control box 207, and a purification control motor 213 is fixedly installed on the top of the supporting frame 212, and the output shaft of the purification control motor 213 is connected to a support plate, and radial extension rods 214 corresponding to the oblique force-bearing plates 308 are fixedly provided on the peripheral side of the support plate, and the ends of the radial extension rods 214 are fitted on the inclined surfaces of the corresponding oblique force-bearing plates 308.

[0039] In the initial state, each elastic element 311 is in a natural state, each radial extension rod 214 is in contact with the corresponding oblique force-bearing plate 308, the second through-hole 401 on the gel filling cylinder 4 is always aligned with the first conducting port 204, and the first through-hole 302 on the gel dissipation cylinder 301 is in a cross-staggered position relationship with the second through-hole 401 on the gel filling cylinder 4 (that is, the first through-hole 302 is blocked by the arc-shaped blocking ring 206 at this time). When the machine 213 controls the radial extension rods 214 to rotate simultaneously, the radial extension rods 214 can push the corresponding oblique force-bearing plates 308, so that the transmission tooth plate 307 slides along the corresponding guide groove 211 and compresses the elastic element 311, until the transmission tooth plate 307 drives the transmission gears 306 to rotate 90 degrees synchronously, at which time the first through-hole 302 on the gel dissipation cylinder 301 is aligned with the second through-hole 401 on the gel filling cylinder 4, and then the room air filtered by the dust filter 5 is The internal air enters the air filter cartridge 303 through the dust filter strip hole 305, and then passes through the second arc vent at the bottom of the air filter cartridge 303 and the first arc vent 209 on the partition plate 208 to enter the space below the partition plate 208. Then the air flow passes through the first through-hole 302 on the gel dissipation cartridge 301 and the second through-hole 401 on the gel filling cartridge 4 to enter the interior of the gel filling cartridge 4, and then passes through the second through-hole 401 on the gel filling cartridge 4 and the gel dissipation cartridge 4 to enter the interior of the gel filling cartridge 4. The first through-hole 302 and the first conducting port 204 on 301 enter into the guide channel 203, and then enter into the inner cavity of the annular partition plate 201 through the second conducting port 205, thereby the chlorine dioxide gas volatilized in each gel filling tube 4 can be purged and transported to the closed inner cavity of the annular partition plate 201 through the dust-filtering air flow, and the indoor air and the chlorine dioxide gas are fully contacted in the inner cavity of the annular partition plate 201 (increasing the contact time), which can greatly improve the purification effect of formaldehyde in the indoor air.

[0040] When the air pressure in the inner cavity of the annular partition plate 201 is close to the set pressure threshold, the mixed air flow is stopped from being delivered to the inner cavity of the annular partition plate 201 and the mixed gas therein is started to be extracted, and at the same time, the purification control motor 213 controls each radial extension rod 214 to rotate in the opposite direction at the same time, and under the elastic restoring force of the elastic element 311, each transmission tooth plate 307 slides in the opposite direction along the corresponding guide groove 211 and resets until the first through-hole 302 on the gel dissipation cylinder 301 returns to the initial position, that is, the first through-hole 302 on the gel dissipation cylinder 301 is in a cross-staggered position relationship with the second through-hole 401 on the gel filling cylinder 4 again, and then the mixed gas in the inner cavity of the annular partition plate 201 can be discharged to realize the backwashing of each dust filter 5.

[0041] Specific embodiment 2, on the basis of specific embodiment 1, the present invention also includes a lifting and conveying mechanism 6; wherein, the lifting and conveying mechanism 6 includes a support base 601, two vertical fixed columns 602 are symmetrically fixedly arranged on the top of the support base 601, two outer extension plates 215 are symmetrically fixedly arranged on the side surface of the purification control box 207, the outer extension plates 215 are fixedly connected to the corresponding vertical fixed columns 602, and a lifting and conveying platform 603 is slidingly sleeved between the two vertical fixed columns 602; a lifting control motor 604 is fixedly installed on the top of the support base 601, and a lifting screw 605 that is threadedly matched with the lifting and conveying platform 603 is connected to the output end of the lifting control motor 604, and a plurality of positioning rings 606 are arranged in an annular array on the top of the lifting and conveying platform 603, and the positioning ring 606 is arranged coaxially with the corresponding vertical installation cylinder 202, and the gel The filling cylinder 4 is plugged into the corresponding positioning ring 606, and a plug-in groove 607 is provided on the inner side of the positioning ring 606. A plug-in part 402 that cooperates with the corresponding plug-in groove 607 is fixedly provided at the bottom of the gel filling cylinder 4, and a sealing cover 403 is installed on the top of the gel filling cylinder 4. After each gel filling cylinder 4 is plugged into the corresponding positioning ring 606, the lifting and lowering screw 605 is controlled to rotate by the lifting control motor 604. Under the threaded cooperation of the lifting screw 605 and the lifting and conveying platform 603, the entire lifting and conveying platform 603 is driven to move upward with each gel filling cylinder 4 until the positioning ring 606 is tightly against the bottom of the purification control box 207, thereby installing each gel filling cylinder 4 into the corresponding vertical installation cylinder 202 (specifically, the gel filling cylinder 4 is installed into the gel dissipation cylinder 301).

[0042] In this embodiment of the present invention, the vertical installation cylinder 202 is connected to the corresponding guide channel 203 through the third conduction port 216. The first conduction port 204 and the third conduction port 216 are both arranged below the separation plate 208. An arc-shaped sealing plate 312 for sealing the third conduction port 216 is fixedly arranged on the side surface of the gel dissipation cylinder 301. The position of the arc-shaped sealing plate 312 in the initial state corresponds to the first through dissipation hole 302, that is, the arc-shaped sealing plate 312 and the third conduction port 216 are in a cross-staggered position. At this time, the third conduction port 216 is in an open state. When the first through dissipation hole 302 is controlled to align with the second through dissipation hole 401, the first through dissipation hole 302, the second through dissipation hole 401 and the first conduction port 204 are connected to each other, and the third conduction port 216 is blocked by the arc-shaped sealing plate 312. The indoor air entering the space below the separation plate 208 can only pass through the first through dissipation hole 302 in sequence. The first through-hole 302, the second through-hole 401 and the first conducting port 204 enter into the guide channel 203, and then enter into the inner cavity of the annular partition plate 201 through the second conducting port 205. When the mixed air flow to the inner cavity of the annular partition plate 201 stops being transported and the mixed gas therein begins to be extracted, the first through-hole 302 on the gel dissipation tube 301 is controlled to return to the initial position. At this time, the arc-shaped sealing plate 312 returns to the initial position to release the blockage of the third conducting port 216. Subsequently, under the action of suction, the mixed gas in the inner cavity of the annular partition plate 201 enters into the guide channel 203 along the second conducting port 205, and then enters into the space below the partition plate 208 through the third conducting port 216. Subsequently, the mixed gas passes through the first arc-shaped vent 209 and the second arc-shaped vent in turn into the air filter tube 303. The mixed gas entering into the air filter tube 303 backwashes the dust filter 5.
