Description

Technical Field

[0001] The present invention relates to the technical field of air purification equipment, and in particular to a mobile indoor air purification device. Background Art

[0002] As people's requirements for quality of life continue to improve, they also pay more and more attention to their own health, but air pollution is becoming more and more serious. Inhalable particles in the air, harmful gases released by indoor decoration materials, bacteria and molds that grow and reproduce in air conditioners and carpets are all harmful to people's health at all times, so people use air purifiers to improve indoor air quality.

[0003] After searching, the existing patent (Announcement No.: CN207065725U) discloses a mobile indoor air purification device, which includes a housing, an air purification filter system, two layers of photocatalyst filters, a partition, a negative ion generator, etc. The air purification filter system includes a pre-filter, a HEPA filter, and an activated carbon filter. There is an ultraviolet lamp between the two layers of photocatalyst filters. The mobile air purification device provided by the patent uses the catalytic effect of photocatalysts to decompose and kill organic harmful substances in the air and finally convert them into harmless substances, which can be moved conveniently and quickly.

[0004] In addition, after searching, the existing patent (Announcement No.: CN210772549U) discloses a mobile indoor air purification device, including a shell with an installation path inside the shell. The patent has a reasonable structure, and the ultraviolet germicidal lamp can emit stable ultraviolet light, which is beneficial to the purification of the air by the ultraviolet germicidal lamp. The shell is pushed so that the shell can be moved to different positions, and the upper and lower fans are started to suck the outside air into the shell through the filter net, and the air is purified by the purification device, and then the purified air is discharged to complete the purification of the indoor air.

[0005] However, there are still some shortcomings in the above solutions and the traditional air purification equipment currently on the market:

[0006] 1. During the operation of air purification equipment, using ultraviolet lamps to sterilize the air is an extremely important part, but the ultraviolet lamp needs to meet two basic conditions to fully sterilize the air. One is the distance between the ultraviolet lamp and the air, and the other is the action time between the ultraviolet lamp and the air. Existing traditional air purification equipment uses a blower to achieve the circulation of airflow. The fast-flowing airflow has a short reaction time with the ultraviolet lamp, resulting in poor sterilization effect. In order to fully sterilize the air, multiple sets of ultraviolet lamps are often set, which will greatly increase the production and use costs.

[0007] 2. Ultraviolet disinfection lamps will produce ozone during the air disinfection process. With the rapid increase of indoor ozone concentration, high concentration of ozone is harmful to human health. Ozone exposure is closely related to death, respiratory and cardiovascular diseases. High concentration exposure can cause premature death, asthma, respiratory infections and other health problems. Therefore, how to achieve air purification while controlling the emission concentration of ozone is an urgent problem that indoor air purification equipment needs to solve.

[0008] 3. Existing air purification equipment does not have good anti-collision and anti-fall performance. When the equipment is hit or tipped over, the strong vibration can easily damage the internal components of the air purification equipment. In addition, existing air purification equipment usually has a cylindrical filter mechanism, which makes the installation and removal of the filter mechanism troublesome and inconvenient, and is not conducive to subsequent maintenance and repair work. The large-area cylindrical outer filter is prone to clogging after long-term use, which is not convenient for quick and thorough cleaning. Summary of the invention

[0031] Preferably, two support frames are symmetrically fixed to the bottom end of the bottom frame, and two universal wheels are symmetrically arranged at the bottom of the two support frames.

[0032] The working principle and beneficial effects of the present invention are:

[0033] 1. In the present invention, a sterilization mechanism is arranged between the upper frame and the bottom frame. After the bottom frame is sucked by the blower to form a negative pressure, the filtered air inside the bottom frame enters the blower through the first air intake pipe, and then is discharged into the inner side of the chassis through the first air outlet pipe. As the air pressure inside the chassis increases rapidly, the gas inside the chassis is discharged into the center tube through the exhaust inclined hole. The oblique exhaust inclined hole enables the airflow entering the center tube to flow upward in a spiral shape to a great extent. The ingenious structural design enables the airflow to spirally flow upward from the bottom of the ultraviolet germicidal lamp around the outer side of the ultraviolet germicidal lamp, thereby increasing the reaction time and contact area between the airflow and the ultraviolet germicidal lamp, so that the ultraviolet germicidal lamp can sterilize and disinfect the airflow more fully.

[0034] 2. In the present invention, a suitable purification method can be selected according to the actual purification needs. When purifying the air in a room with people, a proper amount of aqueous solution is pre-filled in the annular cavity, and the air containing ozone in the central tube is collected into the gas collecting cover, and finally discharged into the hollow ball through the air pipe, and discharged into the solution through the micropores on the hollow ball, forming a large number of tiny bubbles. With the high-frequency vibration of the atomizing sheet, the ozone gas is gradually dissolved in the aqueous solution, thereby greatly reducing the ozone concentration. The remaining gas will be discharged into the room through the exhaust pipe and the exhaust hood, and the gas discharged into the room can assist the ozone water mist atomized by the atomizing sheet to be discharged through the exhaust pipe, which can achieve humidification of the room while reducing the emission of ozone. In addition, after a proper amount of solution is filled in the annular cavity, the atomizing sheet is not started. The high solubility of ozone in water is utilized so that the mixed gas containing ozone discharged through the micropores on the hollow ball is filled into the solution to form a large number of tiny bubbles. In the process of the bubbles moving upward, most of the ozone gas gradually dissolves in the aqueous solution, and the remaining gas is discharged through the exhaust pipe, which greatly improves the safety performance of the purification device, breaks through the shortcomings of the prior art in the field of indoor air purification, has high use value and outstanding progress, and has broad application prospects and markets;

[0035] 3. In the present invention, when air is purified in an unmanned room: according to the above method, only the sealing plug on the lower side needs to be opened to discharge the solution inside the annular cavity, and the atomizer needs to be closed, so that the gas sterilized by the ultraviolet germicidal lamp can be directly discharged into the annular cavity through the gas pipe and the hollow ball, and directly discharged into the room through the exhaust pipe and the exhaust hood. The generated high concentration of ozone gas can further disinfect and sterilize the room. The setting of the guide groove can better collect the gas inside the annular cavity into the exhaust pipe for discharge. It has a simple structure, ingenious design, and good practical performance.

[0036] 4. In the present invention, when the device falls over or is hit by an external object, the outer guard bar at the periphery will be collided in advance, and the outer guard bar will move closer to the connection cover under the impact. In this process, the outer guard bar pushes the first rotating rod and the second rotating rod. The outer walls of the two hinged seats are fixed with T-shaped sliders. The outer guard bar is provided with a sliding groove with a T-shaped cross section. The T-shaped slider moves along the inside of the T-shaped sliding groove, and the movement directions of the two hinged seats are opposite and move away from each other. Similarly, the first rotating rod and the second rotating rod push the two polygonal rings, so that the two polygonal rings move away from each other, compressing the support spring, thereby buffering and offsetting the impact force received by the device, and providing a certain degree of anti-collision and anti-fall protection for the device;

[0037] 5. In the present invention, after a long period of use, a large amount of dirt will be intercepted on the surface of the outermost wire mesh, and the dirt will clog the mesh holes of the reset spring, which is not conducive to the outside air entering the bottom frame. At this time, any one of the outer guard rods is pushed back and forth, so that the two polygonal rings move away from or close to each other, driving all the outer guard rods to move closer to or away from the center of the sterilization mechanism. At this time, the outer guard rods in the front, back, left and right directions will synchronously push or pull the connecting rod, so that the connecting rod switches between the inclined and vertical states. During this process, the connecting rod can reciprocate up and down the lifting frame, so that the cleaning brushes distributed on the lifting frame can frictionally clean the outer surface of the filter mechanism, thereby realizing synchronous cleaning of multiple filter mechanisms and greatly improving the cleaning efficiency.

[0038] 6. In the present invention, when the filter mechanism is cleaned, the shutoff valves on the first air outlet pipe and the first air intake pipe respectively block the first air outlet pipe and the first air intake pipe, while the second air outlet pipe and the second air intake pipe are in a connected state. The blower draws air through the second air intake pipe and discharges it through the second air outlet pipe, so that the air pressure inside the bottom frame increases, and the gas inside the bottom frame is discharged outward through multiple filter mechanisms at the same time. In conjunction with the cleaning of the cleaning mechanism, the dirt on the surface of the filter mechanism can be cleaned smoothly, effectively preventing the dirt from floating into the inside of the filter mechanism during cleaning, and further improving the cleaning efficiency;

[0039] 7. In the present invention, the filter mechanism is installed in a detachable manner, which is more convenient and quicker to use than the traditional cylindrical installation. When the filter mechanism needs to be replaced, the right-angled clips on the inner sides of the two movable grooves are pressed at the same time, so that the two right-angled clips are close to each other, and the right-angled clips are pulled out from the slot on one side of the installation cavity. At this time, the entire filter mechanism can be disassembled. Similarly, when installing the filter mechanism, the right-angled clips on the inner sides of the two movable grooves are pressed at the same time, and the filter mechanism is sleeved on the inner side of the installation cavity. After that, the pressure on the movable groove is released. Under the action of the reset spring, the right-angled clip is reset and inserted into the slot to complete the installation of the filter mechanism. The operation is simple and easy to use.

[0069] In this embodiment, the atomizing sheet 1402 on the tray 1401 is started, and the blower 801 is started. The atomizing sheet 1402 is an ultrasonic vibrator.

[0077] Furthermore, the filtering mechanism 5 includes an assembly frame 501 which is sleeved on the inner side of the installation cavity 201, and the upper and lower outer walls of the assembly frame 501 are provided with movable grooves 502, and a right-angle clamping plate 503 is slidably sleeved inside the movable groove 502, and the vertical plate of the right-angle clamping plate 503 slides and extends out of the outer wall of the assembly frame 501, and a slot for inserting the vertical plate of the right-angle clamping plate 503 is provided on one side of the installation cavity 201, and a guide column 504 is fixedly connected to the inside of the movable groove 502, and the guide column 504 slides through the inside of the horizontal plate of the right-angle clamping plate 503, and a reset spring 505 is sleeved on the outer wall of the guide column 504, and a wire mesh 508, a nylon mesh 507, a fiber mesh 506 and an activated carbon layer 509 are sleeved in sequence from the outside to the inside of the assembly frame 501.

[0078] Furthermore, the cleaning mechanism 6 includes a lifting frame 602 slidably connected to the outer wall of the assembly frame 501 , a cleaning brush 603 is distributed on the outer wall of the lifting frame 602 close to the wire mesh 508 , and a connecting rod 601 is hingedly connected between the outer protective rod 706 and the lifting frame 602 .

[0079] In this embodiment, after a long period of use, a large amount of dirt will be intercepted on the surface of the outermost wire mesh 508, and the dirt will clog the mesh holes of the return spring 505, which is not conducive to the outside air entering the bottom frame 2. At this time, it is necessary to clean the surface of the wire mesh 508, and push any one of the outer guard rods 706 back and forth to make the two polygonal rings 701 move away from or close to each other, driving all the outer guard rods 706 to move closer to or away from the center of the sterilization mechanism 3. At this time, the outer guard rods 706 in the front, back, left and right directions will synchronously push or pull the connecting rod 601, so that the connecting rod 601 switches between the inclined and vertical states. During this process, the connecting rod 601 can reciprocate up and down the lifting frame 602, so that the cleaning brushes 603 distributed on the lifting frame 602 can frictionally clean the outer surface of the filter mechanism 5, thereby realizing synchronous cleaning of multiple filter mechanisms 5. At the same time, the shut-off valves on the first air outlet pipe 804 and the first air intake pipe 802 respectively block the first air outlet pipe 804 and the first air intake pipe 802, while the second air outlet pipe 805 and the second air intake pipe 803 are in a connected state. The blower 801 draws air through the second air intake pipe 803 and discharges it through the second air outlet pipe 805, so that the air pressure inside the bottom frame 2 increases, and the internal gas of the bottom frame 2 is discharged outward through multiple filtering mechanisms 5 at the same time. Combined with the cleaning of the cleaning mechanism 6, the dirt on the surface of the filtering mechanism 5 can be cleaned smoothly, effectively preventing dirt from floating into the inside of the filtering mechanism 5 during cleaning, which has good practicality.

[0080] Working principle and usage process: When working, first of all, choose the appropriate purification method according to the actual purification needs.

[0081] When air is purified in a room where people are present: the upper sealing plug 15 is pulled out from the connecting cover 301, and the aqueous solution 13 is injected into the annular cavity 302, and the hollow ball 1102 is immersed in the solution 13, and the exhaust pipe 901 is located above the solution 13. After that, the atomizing sheet 1402 on the tray 1401 is started, and the blower 801 is started. The atomizing sheet 1402 is an ultrasonic vibrator, and the atomizing sheet 1402 and the blower 801 can be powered by an external power supply or a rechargeable lithium battery. It is an existing mature technology and will not be described in detail here. When the atomizing sheet 1402 is working, it beats the water surface into extremely fine water molecules through high-frequency vibration to produce water mist. At the same time, the shut-off valves on the second air outlet pipe 805 and the second air intake pipe 803 respectively block the second air outlet pipe 805 and the second air intake pipe 803, while the first air outlet pipe 804 and the first air intake pipe 802 are in a connected state. The blower 801 sucks the air inside the bottom frame 2 through the first air intake pipe 802, so that a negative pressure is formed inside the bottom frame 2, so that the external air is filtered through the steel mesh 508, the nylon mesh 507, the fiber mesh 506 and the activated carbon layer 509 in sequence and enters the bottom frame 2. The filtered air inside the bottom frame 2 enters the blower 801 through the first air intake pipe 802. 1, and then discharged into the inside of the chassis 304 through the first air outlet pipe 804. As the air pressure in the chassis 304 increases rapidly, the gas in the chassis 304 is discharged into the inside of the central tube 306 through the exhaust inclined hole 305. The inclined exhaust inclined hole 305 allows the airflow entering the inside of the central tube 306 to flow upward in a spiral shape to a great extent, so that the airflow can spirally flow upward from the bottom of the ultraviolet germicidal lamp 10 around the outside of the ultraviolet germicidal lamp 10, thereby increasing the reaction time and contact area between the airflow and the ultraviolet germicidal lamp 10, so that the ultraviolet germicidal lamp 10 can sterilize and disinfect the airflow more fully.

[0082] The ultraviolet germicidal lamp 10 will produce a lot of ozone during the process of sterilizing the air. Although ozone helps to disinfect and purify the air, high concentrations of ozone are harmful to human health. Ozone exposure is closely related to death, respiratory and cardiovascular diseases. High concentrations of exposure can cause premature death, asthma, respiratory infections and other health problems. Therefore, when purifying the air in a room where people are present, an appropriate amount of solution 13 is pre-filled in the annular cavity 302, and the air containing ozone in the central tube 306 is gathered into the gas collecting cover 12, and finally discharged into the hollow ball 1102 through the air supply pipe 1101, and discharged into the solution 13 through the micropores on the hollow ball 1102, forming a large number of tiny bubbles. With the high-frequency vibration of the atomizing sheet 1402, the ozone gas is gradually dissolved in the aqueous solution 13, thereby greatly reducing the ozone concentration, and the remaining gas will be discharged into the room through the exhaust pipe 901 and the exhaust hood 902, and the gas discharged into the room can assist the ozone water mist atomized by the atomizing sheet 1402 to be discharged through the exhaust pipe 901, which can achieve humidification of the room while reducing the emission of ozone.

[0083] In addition, after a proper amount of solution 13 is placed inside the annular cavity 302, the atomizing sheet 1402 may not be activated. By utilizing the high solubility of ozone in water, the mixed gas containing ozone discharged through the micropores on the hollow ball 1102 is filled into the solution 13 to form a large number of tiny bubbles. In the process of the bubbles moving upward, most of the ozone gas gradually dissolves in the aqueous solution 13, and the remaining gas is discharged through the exhaust pipe 901, thereby greatly improving the safety performance of the purification device.

[0084] When purifying the air in an unmanned room: According to the above method, only the sealing plug 15 on the lower side needs to be opened to discharge the solution 13 in the annular cavity 302, and the atomizer 14 needs to be closed, so that the gas sterilized by the ultraviolet germicidal lamp 10 can be directly discharged into the annular cavity 302 through the gas pipe 1101 and the hollow ball 1102, and directly discharged into the room through the exhaust pipe 901 and the exhaust hood 902, and the generated high concentration of ozone gas can further disinfect and sterilize the room. The setting of the guide groove 303 can better collect the gas inside the annular cavity 302 into the exhaust pipe 901 for discharge.

[0085] When the device topples over or is hit by an external object, the outer guard rod 706 on the periphery will be collided in advance. The outer guard rod 706 will move closer to the connecting cover 301 due to the impact. During this process, the outer guard rod 706 pushes the first rotating rod 704 and the second rotating rod 707. The outer walls of the two hinged seats 705 are fixed with T-shaped sliders. The outer guard rod 706 is provided with a sliding groove with a T-shaped cross-section. The T-shaped slider moves along the inside of the T-shaped sliding groove, and the movement directions of the two hinged seats 705 are opposite and move away from each other. Similarly, the first rotating rod 704 and the second rotating rod 707 push the two polygonal rings 701, so that the two polygonal rings 701 move away from each other and compress the support spring 703, so as to buffer and offset the impact force applied to the device and provide a certain degree of anti-collision and anti-fall protection for the device.

[0086] After a long period of use, a large amount of dirt will be intercepted on the surface of the outermost wire mesh 508, which will clog the mesh holes of the return spring 505, preventing outside air from entering the bottom frame 2. At this time, the surface of the wire mesh 508 needs to be cleaned, and any one of the outer guard rods 706 can be pushed back and forth to make the two polygonal rings 701 move away from or close to each other, driving all the outer guard rods 706 to move closer to or away from the center of the sterilization mechanism 3. At this time, the outer guard rods 706 in the front, back, left and right directions will synchronously push or pull the connecting rod 601, so that the connecting rod 601 switches between the inclined and vertical states. During this process, the connecting rod 601 can reciprocate up and down the lifting frame 602, so that the cleaning brushes 603 distributed on the lifting frame 602 can frictionally clean the outer surface of the filter mechanism 5, thereby realizing synchronous cleaning of multiple filter mechanisms 5. At the same time, the shut-off valves on the first air outlet pipe 804 and the first air intake pipe 802 respectively block the first air outlet pipe 804 and the first air intake pipe 802, while the second air outlet pipe 805 and the second air intake pipe 803 are in a connected state. The blower 801 draws air through the second air intake pipe 803 and discharges it through the second air outlet pipe 805, so that the air pressure inside the bottom frame 2 increases, and the internal gas of the bottom frame 2 is discharged outward through multiple filtering mechanisms 5 at the same time. Combined with the cleaning of the cleaning mechanism 6, the dirt on the surface of the filtering mechanism 5 can be cleaned smoothly, effectively preventing dirt from floating into the inside of the filtering mechanism 5 during cleaning, which has good practicality.

[0087] After a long period of work, when the filter mechanism 5 needs to be replaced, the right-angled clamps 503 on the inner sides of the two movable grooves 502 are pressed at the same time, so that the two right-angled clamps 503 are close to each other, so that the right-angled clamps 503 are pulled out from the slot on one side of the installation cavity 201, and the entire filter mechanism 5 can be disassembled. Similarly, when installing the filter mechanism 5, the right-angled clamps 503 on the inner sides of the two movable grooves 502 are pressed at the same time, and the filter mechanism 5 is sleeved on the inner side of the installation cavity 201. After that, the pressure on the movable groove 502 is released, and under the action of the reset spring 505, the right-angled clamps 503 are reset and inserted into the slot, completing the installation of the filter mechanism 5.
