Description

Technical Field

[0001] This invention relates to the field of air purifiers, and more specifically, to an indoor air purifier. Background Technology

[0002] Household air purifiers are mainly used to remove indoor air pollutants (generally including dust, pollen, odors, formaldehyde and other decoration pollution, bacteria, allergens, etc.), effectively improving air cleanliness. Air purifiers typically consist of a high-voltage circuit, a negative ion generator, a fan, and an air filter. When the purifier is running, the fan inside the machine circulates the air in the room or car. The polluted air is filtered through the air filter inside the machine, removing or adsorbing various pollutants. Then, the negative ion generator installed at the air outlet continuously ionizes the air, generating a large number of negative ions, which are sent out by the micro fan to form a negative ion flow, thus achieving the purpose of cleaning and purifying the air.

[0003] Household air purifiers employ various methods to capture particulate matter. They are effective at collecting fine particles, but have high air resistance. To achieve higher purification efficiency, the filter needs to be dense and replaced regularly. Adsorption utilizes the large surface area and porous structure of materials to capture particulate pollutants, but it is prone to clogging. It is more effective at removing gaseous pollutants. Electrostatic dust removal uses a high-voltage electrostatic field to ionize the gas, thereby charging dust particles and adsorbing them onto the electrodes. Although it has low air resistance, it is less effective at capturing larger particles and fibers, can cause discharge, and is troublesome and time-consuming to clean. It can also easily generate ozone, leading to secondary pollution.

[0004] In existing technologies, smoke is composed of PM0.3 ultrafine particles, tar, volatile organic compounds, and odor molecules. Smoke diffuses quickly and easily adheres to surfaces. Floor-standing air purifiers, with their low air intake, cannot capture rising smoke in time. Wall-mounted air purifiers, on the other hand, use a high air intake to quickly intercept smoke during its initial diffusion stage. However, smoking areas are not fixed in homes; smoking can occur in bedrooms, living rooms, and bathrooms. Installing wall-mounted air purifiers in all these areas would increase costs. Summary of the Invention

[0014] Furthermore, magnetic blocks are fixedly connected to the opposing surfaces of the front and rear support plates.

A gear is provided on the lower half of the first rack and a gear is provided on the upper half of the second rack.

[0015] Furthermore, conductive components are provided on both the inner and outer sides of the body, and the conductive components include a drive motor disposed inside the body.

[0016] Furthermore, a fan is fixedly connected to the output end of the drive motor, a bearing is provided on the upper side of the inside of the drive motor, a wire runs through the right side of the inside of the drive motor, a grounding end is fixedly connected to the lower right end of the wire, a positioning end is fixedly connected to the upper right end of the wire, a lifting plate overlaps the upper right side of the machine body, the lifting plate partially wraps around the outside of the positioning end, an electric push rod is fixedly connected to the upper right side of the inside of the machine body, and the telescopic end of the electric push rod is fixedly connected to the lower side of the lifting plate.

[0017] Furthermore, the drive motor has a movable slot inside, an insulating sleeve is inserted into the movable slot, a fixed ring is slidably connected inside the insulating sleeve, conductive plates are fixedly connected to both the left and right sides of the upper end of the fixed ring, the left end of the wire is fixedly connected to the right side of the fixed ring, a laser rangefinder is provided on the right side of the inner wall of the movable slot, a limit groove is formed on the right side of the inner wall of the movable slot, the right extension of the fixed ring passes through the insulating sleeve and is slidably connected inside the limit groove, a pressure spring is fixedly connected between the right side of the fixed ring and the right side of the limit groove, and the pressure spring is sleeved on the outside of the wire.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] (1) The present invention extracts smoke in time after the suction head moves upward and quickly changes the working position. When the machine body moves to the smoking environment by means of the brake wheel, the height of the suction head at the top can be raised, so that the suction head can capture the rising smoke in time and avoid the smoke from being difficult to extract due to rapid diffusion. At the same time, the freely movable machine body can quickly change the working environment, thereby improving the flexibility of the machine body.

[0020] (2) The present invention uses a connecting rod to pull the suction head after the slider can no longer move, which changes the orientation angle of the suction head. When the cylinder extends to its maximum height, the opening orientation of the suction head will rotate from a parallel state to an upward tilting state, which increases the suction head’s extraction height of smoke and further improves the machine’s smoke processing efficiency.

[0021] (3) The present invention uses a support plate that contacts the ground when the suction head reaches its highest position and supports the machine body. As the height of the suction head changes, the height of the support plate also changes accordingly. When the suction head reaches its highest position, the support plate contacts the ground, which avoids the decrease in machine body stability caused by the suction head being raised too high, thereby ensuring the stability of the machine body.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1 to 8An indoor air purifier includes a body 1 and brake wheels 11 arranged in a ring array and fixedly connected to the lower side of the body 1. An extension component 2 is provided on both the inner and outer sides of the body 1. The extension component 2 includes a cylinder 21 fixedly connected to the upper left side of the body 1.

[0034] A first conveying pipe 22 is fixedly connected to the upper side of the body 1. A second conveying pipe 23 is slidably connected through the upper side of the first conveying pipe 22. A fixed seat 24 is fixedly connected to the upper side of the second conveying pipe 23. The telescopic end of the cylinder 21 is fixedly connected to the lower side of the fixed seat 24. A hose 25 is fixedly connected inside the fixed seat 24. An air intake head 27 is hinged to the right side of the fixed seat 24. The right end of the hose 25 is fixedly connected to the left side of the air intake head 27. A baffle 26 is fixedly connected to the upper side of the fixed seat 24. The lower side of the baffle 26 is in contact with the upper left side of the air intake head 27.

[0035] The first delivery pipe 22 is connected to the hose 25 inside the fixed base 24, and the fixed base 24 is connected to the suction head 27 through the hose 25.

[0036] Conductive components 3 are provided on both the inner and outer sides of the body 1.

[0037] By adopting the above technical solution, the body 1 can move via the brake wheel 11 below it. When it moves to a smoking environment, the cylinder 21 is activated to lift the fixed base 24 upwards. The left side of the suction head 27 is hinged to the right side of the fixed base 24. When the suction head 27 rotates clockwise due to the upward inertia, the baffle 26 above the suction head 27 will block the suction head 27, preventing it from rotating. During this process, the second delivery pipe 23, which is fixed to the fixed base 24, will move upwards and slide inside the first delivery pipe 22. Then, in conjunction with the conductive component 3, it will draw in outside air. At the same time, the opening on the lower right side of the body 1 will also draw in air. After the conductive component 3 generates suction, the outside air will be drawn into the duct by the suction head 27. The other end of the conduit extends into the interior of the second delivery pipe 23, and the first delivery pipe 22 is connected to the second delivery pipe 23, so that gas enters the interior of the machine body 1 through the first delivery pipe 22. The gas entering the interior of the machine body 1 is discharged from the left side after being processed by the mechanism configured in the machine body 1. When in a non-smoking environment, the opening on the lower right side of the machine body 1 will draw in air and discharge it from the left side after processing. When the machine body 1 moves to a smoking environment by means of the brake wheel 11, the height of the upper suction head 27 can be raised, so that the suction head 27 can capture the rising smoke in time and avoid the smoke from being difficult to extract due to rapid diffusion. At the same time, the freely movable machine body 1 can quickly change the working environment, thereby improving the flexibility of the machine body 1.

[0038] like Figures 1 to 4 and Figure 7 and Figure 8 As shown, the upper side of the body 1 is provided with an adjustment component 28, and the adjustment component 28 includes a hinge seat 281 fixedly connected to the lower left end of the suction head 27.

[0039] A connecting rod 282 is hinged inside the hinge seat 281. A slider 284 is fixedly connected to the bottom end of the connecting rod 282. A groove 283 is opened on the right side of the first conveying pipe 22. The slider 284 is slidably connected inside the groove 283.

[0040] By adopting the above technical solution, when the suction head 27 is about to move to the highest extension position, the hinge seat 281 fixed on the left side of the suction head 27 will drive the connecting rod 282 to move together. During this process, the slider 284 fixed below the connecting rod 282 will slide inside the slide groove 283 on the right side of the first conveying pipe 22. When the slider 284 moves to the top of the slide groove 283, the slider 284 can no longer move, while the fixed seat 24 continues to move upward. At this time, the connecting rod 282 will pull the hinge seat 281. After the hinge seat 281 is pulled, the suction head 27 will rotate counterclockwise at a small angle with the help of the fixed seat 24, so that the opening orientation of the suction head 27 changes. Since the opening orientation of the suction head 27 will rotate from a parallel state to an upward tilted state when the cylinder 21 extends to its maximum height, the suction head 27 increases the extraction height of the smoke, further improving the smoke processing efficiency of the machine body 1.

[0041] like Figures 2 to 4 and Figure 7 and Figure 8 As shown, the inner and outer sides of the body 1 are provided with a support component 29, and the support component 29 includes a fixing plate 291 fixedly connected to the front and rear sides of the fixing base 24.

[0042] The upper sides of both the front and rear ends of the body 1 are provided with first guide grooves 292, and the front and rear sides of the body 1 are provided with second guide grooves 293. The lower side of the fixed plate 291 is fixedly connected to a first rack 294. The first rack 294 is slidably connected inside the first guide groove 292. The second rack 295 is slidably connected inside the second guide groove 293. The front and rear sides of the body 1 are rotatably connected to gears 296. The opposite surfaces of the first rack 294 and the second rack 295 on the left and right sides are meshed with the outer side of the gear 296. The lower side of the second rack 295 is fixedly connected to a support plate 297.

[0043] Magnets 298 are fixedly connected to the opposite surfaces of the front and rear support plates 297. The magnets 298 are magnetically attracted to the inner wall of the second guide groove 293. The support plates 297 are slidably connected to the lower side inside the second guide groove 293. The lower half of the first rack 294 is provided with a gear 296, and the upper half of the second rack 295 is provided with a gear 296.

[0044] By adopting the above technical solution, during the upward movement of the fixed base 24, the fixed plates 291 on both sides of the fixed base 24 will simultaneously drive the two first racks 294 to move upward within the two first guide grooves 292. When the teeth of the first rack 294 mesh with the gear 296, the first rack 294, which continues to move upward, will drive the gear 296 to rotate inside the body 1. At this time, the rotating gear 296 will drive the second rack 295 on its other side to move downward within the second guide groove 293. After the second rack 295 moves downward, the support fixed below the second rack 295... Plate 297 moves downward inside the second guide groove 293. At this time, the magnetic block 298 on the side of the support plate 297 is always attracted to the inner wall of the second guide groove 293. When the first rack 294 can no longer move upward, the support plate 297 will also contact the ground and support the body 1. As the height of the suction head 27 changes, the height of the support plate 297 will also change accordingly. When the suction head 27 reaches the highest position, the support plate 297 will contact the ground, which avoids the suction head 27 from being raised too high and causing the stability of the body 1 to decrease, thereby ensuring the stability of the body 1.

[0045] like Figures 4 to 6 As shown, the conductive component 3 includes a drive motor 31 disposed inside the body 1.

[0046] A fan 32 is fixedly connected to the output end of the drive motor 31. A bearing 33 is provided on the upper side of the inside of the drive motor 31. A wire 34 is provided through the right side of the inside of the drive motor 31. A grounding terminal 35 is fixedly connected to the lower right end of the wire 34. A positioning end 36 is fixedly connected to the upper right end of the wire 34. A lifting plate 37 is attached to the upper right side of the body 1. The lifting plate 37 partially wraps around the outside of the positioning end 36. An electric push rod 38 is fixedly connected to the upper right side of the inside of the body 1. The telescopic end of the electric push rod 38 is fixedly connected to the lower side of the lifting plate 37.

[0047] The drive motor 31 has a moving groove 39 inside, an insulating sleeve 4 is inserted into the moving groove 39, a fixing ring 5 is slidably connected inside the insulating sleeve 4, conductive plates 6 are fixedly connected to the left and right sides of the upper end of the fixing ring 5, the left end of the wire 34 is fixedly connected to the right side of the fixing ring 5, a laser rangefinder 7 is set on the right side of the inner wall of the moving groove 39, a limiting groove 8 is opened on the right side of the inner wall of the moving groove 39, the right extension of the fixing ring 5 passes through the insulating sleeve 4 and is slidably connected inside the limiting groove 8, a pressure spring 9 is fixedly connected between the right side of the fixing ring 5 and the right side inside the limiting groove 8, and the pressure spring 9 is sleeved on the outside of the wire 34.

[0048] By adopting the above technical solution, after the drive motor 31 inside the body 1, in conjunction with the bearing 33, drives the fan 32, the suction head 27 will generate suction. When static electricity accumulates inside the drive motor 31 or current flows through it, because the fixing ring 5 is always surrounded by the outer side of the bearing 33 by the insulating sleeve 4 on its outer side, one of the conductive plates 6 on the upper side of the fixing ring 5 will always be in contact with the outer side of the bearing 33, so that the conductive plate 6 provides a bypass for the current on the outer side of the bearing 33. Then, it is transmitted to the wire 34 through the fixing ring 5 and transferred out through the grounding terminal 35. When the conductive plate 6 in contact with the bearing 33 is sintered due to the current, the surface of the conductive plate 6 will have depressions and protrusions. If protrusions appear, there will be a small gap between the bearing 33 and the conductive plate 6, so that the conductive plate 6 will move a small distance. During this process, the laser rangefinder 7 set on the inner wall of the moving slot 39 can detect in real time. When the data changes and remains for several minutes, the laser rangefinder 7 transmits the information to the body 1. The controller, which is configured to operate the electric push rod 38, then pushes the lifting plate 37 upward. After the lifting plate 37 moves upward, it pushes the positioning end 36 on the upper side of the wire 34, causing the positioning end 36 to pull the wire 34. After the wire 34 is pulled, the end of the wire 34 extending into the limiting groove 8 pulls the extension end of the fixing ring 5 and squeezes the pressure spring 9 inside the limiting groove 8. When the other conductive piece 6 contacts the outside of the bearing 33, the electric push rod 38 stops pushing the lifting plate 37. If the conductive piece 6 continues to move, the body 1 needs to be disassembled and the conductive piece 6 replaced. Since the conductive piece 6 on the outside of the bearing 33 can guide the static electricity or current accumulated inside the drive motor 31, it can prevent local melting and unevenness on the surface of the bearing 33. At the same time, it can detect the conductive piece 6 to monitor its status in real time, thereby ensuring the normal operation of the fan 32 and the smoke extraction efficiency.

[0049] Working principle: The machine body 1 can be moved by the brake wheel 11 below it. When it moves to the smoking environment, the cylinder 21 is activated to lift the fixed base 24 upward, so that the second conveying pipe 23 fixed to the fixed base 24 will move upward and slide inside the first conveying pipe 22. Then, the drive motor 31 inside the machine body 1, in conjunction with the bearing 33, drives the fan 32 to run. At this time, the suction head 27 will generate suction, so that the gas enters the machine body 1. The gas entering the machine body 1 is processed by the mechanism configured in the machine body 1 and then discharged from the left side. When the suction head 27 is about to move to the highest extension position, the left side of the suction head 27 is fixed. The fixed hinge 281 will drive the connecting rod 282 to move together. The slider 284 fixed by the connecting rod 282 will slide inside the groove 283 on the right side of the first conveying pipe 22. When the slider 284 moves to the top of the groove 283, the slider 284 can no longer move, and the connecting rod 282 will pull the hinge 281. The suction head 27 will rotate counterclockwise at a small angle with the help of the fixed seat 24, so that the opening orientation of the suction head 27 changes. During the upward movement of the fixed seat 24, the fixed plates 291 on the front and rear sides of the fixed seat 24 will simultaneously drive the two first racks 294 in the two first guide grooves. The first rack 294 moves upward within the second guide groove 293. When the teeth of the first rack 294 mesh with the gear 296, the upward-moving first rack 294 drives the gear 296 to rotate inside the machine body 1, and drives the second rack 295 to move downward within the second guide groove 293. When the first rack 294 can no longer move upward, the support plate 297 will also contact the ground and support the machine body 1. When static electricity accumulates inside the drive motor 31 or when current flows through it, the conductive plate 6 provides a bypass for the current outside the bearing 33, which is then transmitted to the wire 34 through the fixing ring 5, and then transferred out through the grounding terminal 35. When the conductive sheet 6 in contact with the bearing 33 is sintered due to the current, there will be a small gap between the bearing 33 and the conductive sheet 6, causing the conductive sheet 6 to move a small distance. At this time, the laser rangefinder 7 set on the inner wall of the moving groove 39 can detect it in real time. When the data changes and remains for several minutes, the laser rangefinder 7 transmits the information to the controller configured on the body 1. Then, it controls the electric push rod 38 to push the lifting plate 37 upward and push the positioning end 36 on the upper side of the wire 34, so that the positioning end 36 pulls the wire 34. After the wire 34 is pulled, another conductive sheet 6 contacts the outer side of the bearing 33.
