Description

Technical Field

[0001] This invention relates to an air purifier for use in ultra-large spaces and its method of use. Background Technology

[0002] Air purifiers, also known as air cleaners, air fresheners, or purifiers, are products that can adsorb, decompose, or transform various air pollutants, effectively improving air cleanliness. They are suitable for homes, businesses, industries, buildings, and other settings. The principle of an air purifier is to physically filter indoor air. Polluted air enters the machine through the air inlet, is filtered by the filter, and then clean air is discharged from the air outlet. The lifespan of an air purifier filter is generally only six months, requiring regular replacement. Failure to replace it can lead to secondary pollution. Commonly used air purification technologies include adsorption technology, superstructure photomineralization technology, and photocatalytic technology. Air purifiers mainly consist of a micro fan, air filter (screen), water tank, intelligent monitoring system, negative ion generator, and high-voltage circuit. Although not every product has all of these structures, they represent the majority of product structures.

[0003] Air purifiers are cleaning devices that adsorb dust from the air and purify it by circulating air within the space they are used in. However, existing air purifiers cannot reach every corner of the space they are used in, resulting in slow airflow or even ineffective circulation in spaces far from the purifier. This makes it difficult to filter dust, especially in very large spaces where airflow cannot circulate completely. This requires increasing the power of the fan inside the air purifier, but it is difficult to increase the airflow rate at a constant power, thus reducing the performance of the air purifier. Summary of the Invention

[0004] In order to solve the technical problem that it is difficult to achieve full airflow when using air purifiers in ultra-large spaces, this invention provides an air purifier for use in ultra-large spaces and its method of use.

[0005] To address the shortcomings of existing technologies, this application incorporates a filter screen on the surface of the purifier body to purify dust in the air. Combined with a cover plate, the filter screen can be quickly installed while simultaneously improving airflow efficiency, ensuring efficient airflow in large spaces.

[0006] To further address the issues in existing technologies, an external air supply hood and an internal air supply hood are installed above the main body of the purifier. The air supply angle can be adjusted in multiple dimensions according to usage needs, and it can be quickly adjusted according to the placement of the air purifier, improving ease of use.

[0007] To further address the problems in existing technologies, an external channel is formed between the air supply hoods, allowing the airflow from the inner edge of the outer air supply hood to be discharged in a spiral shape, while the remaining airflow circulates within the inner air supply hood. At the air outlet, the two high-speed streams converge to form a powerful clean airflow, helping to achieve high-speed internal circulation of indoor air. Furthermore, some pollutants that are farther away can also be carried back into the purifier with the airflow, maximizing the uniform purification of ultra-large spaces.

[0017] In this technical solution, a main fan is fixedly installed at the bottom of the air guide shroud, and the outer wall of the air guide shroud is fixedly connected to several sleeves.

[0021] A method of using an air purifier for use in ultra-large spaces, the method comprising the following steps:

[0022] (1) Filter installation: Insert the connecting strip from one end of the access port to the track. Move the two ends of the connecting strip inside the slide rail of the track to push it to the inner wall of the purifier body and align it with the grille hole. Move the cover plate to make the two connecting plates fit together. After the insertion rod passes through one of the connecting plates, tighten the knob to fix the insertion rod, thus fixing the connecting strip and the cover plate. At this time, the second filter on the surface of the cover plate is located inside the access port.

[0023] (2) Air delivery of the purifier: Start the main fan to deliver the air inside the purifier body to the guide hood. When the outside air enters through the grille holes, it is filtered for dust by the first filter screen on the connecting strip. Some air enters through the second filter screen to block the dust.

[0024] (3) The airflow flows rapidly. The airflow located in the center of the guide hood directly enters the inner channel of the inner air supply hood. The airflow located at the edge of the guide hood is guided by the lower guide strip and the upper guide strip, so that the airflow is delivered in a spiral shape, and the airflow is discharged through the outer channel and mixed with the airflow inside the inner channel to accelerate the flow.

[0025] (4) Adjusting the angle of the external air supply hood: Rotate the external air supply hood to make it rotate on the top of the purifier body, and drive the guide hood and friction disc to rotate. During the adjustment process, the friction disc is always in contact with the top of the purifier body. The spring in the sleeve pushes the telescopic rod and the friction disc to move at the same time, so that the friction disc is in close contact with the top of the purifier body, and the adjusted external air supply hood is fixed by friction.

[0026] (5) Adjusting the air supply direction: Start the micro motor on the base plate. The micro motor drives the gear to rotate. Through the meshing with the gear ring, it drives the inner air supply hood to rotate on the limit plate. By setting ball bearings to reduce friction, the orientation of the inner channel is changed. Combined with the angle adjustment of the outer air supply hood, multi-dimensional angle adjustment is achieved.

[0027] (6) Increased air delivery distance: The airflow spirally transported inside the external air delivery hood is discharged from the external channel. The airflow at the baffle is driven by the start of the micro air pump, which transports the airflow through the air inlet pipe and the air outlet pipe to the annular pipe. The airflow in the annular pipe is blown out through the air nozzle and mixed with the airflow in the inner channel to achieve rapid air circulation and prevent turbulence from forming inside the external air delivery hood to increase the air delivery distance and expand the purification space of the air purifier.

[0028] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of the present invention.

[0029] The positive and progressive effects of this invention are as follows:

[0030] The aforementioned air purifier and its usage method for ultra-large spaces feature a filter screen on the surface of the purifier body to purify dust in the air. The cover plate allows for quick filter installation while improving airflow efficiency, ensuring efficient airflow in ultra-large spaces. An external air supply hood and an internal air supply hood are installed above the purifier body, allowing for multi-dimensional adjustment of the air supply angle according to usage needs. This enables quick adjustments based on the placement of the air purifier, improving ease of use. An external channel is formed between the air supply hoods, allowing the airflow from the inner edge of the external air supply hood to be spirally discharged, while the remaining airflow circulates within the internal air supply hood. At the air outlet, the two high-speed streams converge to form a powerful clean airflow, facilitating high-speed internal air circulation within the room. Furthermore, some distant pollutants are carried back into the purifier by the airflow, maximizing uniform purification in ultra-large spaces. Attached Figure Description

[0057] (1) Filter installation: Insert the connecting strip 103 from one end of the access port 101 to the track 102. Move the connecting strip 103 inside the slide rail 111 of the track 102 to push it to the inner wall of the purifier body 100 and align it with the grille hole 105.

The surface of the cover plate (106) is fixedly connected with a second filter screen (107).

5. An air purifier for use in ultra-large spaces as described in claim 4, characterized in that: The purifier body (100) has a hemispherical groove on the top to facilitate the installation of the external air supply hood (200). The bottom wall of the external air supply hood (200) is fixedly connected with several evenly distributed upper guide strips (201). The bottom of the external air supply hood (200) is provided with a frustum-shaped hollow guide hood (202). The inner wall of the guide hood (202) is fixedly connected with several evenly distributed lower guide strips (203). The upper guide strips (201) and the lower guide strips (203) are both inclined and correspond to each other.

6. An air purifier for use in ultra-large spaces as described in claim 5, characterized in that: The main fan (204) is fixedly installed at the bottom of the flow guide (202). The outer wall of the flow guide (202) is fixedly connected to several sleeves (205). Each sleeve (205) is inserted through a telescopic rod (207). The telescopic rod (207) is connected to the inside of the sleeve (205) through a spring (206). The top of each telescopic rod (207) is fixedly connected to a friction disc (208). The friction disc (208) is a bowl-shaped hollow structure and is movably sleeved with the outer wall of the flow guide (202). The inner wall of the friction disc (208) contacts the outer surface of the groove on the top of the purifier body (100).

7. The method of using an air purifier applied to an ultra-large space as described in claim 6, characterized in that: The method of use includes the following steps: (1) Install the filter screen. Insert the connecting strip (103) from one end of the inspection port (101) into the track (102). Move the two ends of the connecting strip (103) inside the slide rail (111) of the track (102) to push it to the inner wall of the purifier body (100) and align it with the grid hole (105). Move the cover plate (106) to make the two connecting plates (112) fit together. Drive the plug rod (108) through one of the connecting plates (112). Tighten the knob (109) to fix the plug rod (108) and fix the connecting strip (103) and the cover plate (106). At this time, the second filter screen (107) on the surface of the cover plate (106) is located inside the inspection port (101). (2) Air delivery of the purifier: Start the main fan (204) to deliver the air inside the purifier body (100) to the guide hood (202). When the outside air enters through the grille hole (105), it is filtered for dust by the first filter screen (104) on the connecting strip (103). Some air enters through the second filter screen (107) to block the dust. (3) The airflow flows rapidly. The airflow located in the center of the guide hood (202) directly enters the inner channel (301) of the inner air supply hood (300). The airflow located at the edge of the guide hood (202) is guided by the lower guide strip (203) and the upper guide strip (201) to make the airflow spiral and deliver the airflow. The airflow is discharged through the outer channel (209) and mixed with the airflow inside the inner channel (301) to accelerate the flow. (4) Adjusting the angle of the external air supply hood (200): By rotating the external air supply hood (200), it rotates on the top of the purifier body (100), and drives the guide hood (202) and friction disc (208) to rotate. During the adjustment process, the friction disc (208) is always in contact with the top of the purifier body (100). The spring (206) inside the sleeve (205) pushes the telescopic rod (207) and the friction disc (208) to move simultaneously, so that the friction disc (208) is in close contact with the top of the purifier body (100), and the adjusted external air supply hood (200) is fixed by friction. (5) Adjusting the air supply direction: Start the micro motor (303) on the base plate (302). The micro motor (303) drives the gear (304) to rotate. Through meshing with the gear ring (403), the inner air supply hood (300) rotates on the limit plate (400). By setting the ball (402) to reduce friction, the orientation of the inner channel (301) is changed. In conjunction with the angle adjustment of the outer air supply hood (200), multi-dimensional angle adjustment is achieved. (6) With the increase of air supply distance, the airflow spirally transported inside the external air supply hood (200) is discharged from the external channel (209). The airflow at the baffle (305) is transported to the annular pipe (309) through the inlet pipe (307) and outlet pipe (308) by starting the micro air pump (306). The airflow in the annular pipe (309) is blown out through the air nozzle (310) and mixed with the airflow in the inner channel (301) to achieve rapid air circulation and prevent turbulence from forming inside the external air supply hood (200) to increase the air supply distance and expand the purification space of the air purifier.
