Description

Technical Field

[0001] This invention relates to the field of air purifiers, and more particularly to an air purifier for public places that intelligently switches working modes. Background Technology

[0002] In existing technologies, due to the risk of germ transmission in public places, indoor air circulation filtration cannot prevent the spread of germs. Furthermore, existing window-type air purifiers cannot meet the ventilation requirements of public places and cannot adjust the ventilation volume according to demand. In addition, replacing the filter of existing window-type air purifiers requires disassembly and reassembly, which is difficult and time-consuming. Moreover, the air purification efficiency and ventilation volume are both low. In addition, existing window-type air purifiers are easily affected by extreme weather conditions and cannot effectively protect windows. Summary of the Invention

[0003] To overcome the shortcomings of existing window-type air purifiers, such as the inability to adjust the air exchange rate according to demand, and the difficulty and time-consuming process of replacing the filter element, this invention provides a public place air purifier with intelligent switching of working modes.

[0004] Technical Solution: A public place air purifier with intelligent switching working modes includes an installation box; it also includes an air intake box, an air intake fan, a filter plate, a filter element, guide rails, folding baffles, and a sponge brush; the installation box is installed on the wall below the window; two air intake boxes are symmetrically arranged on the left and right sides of the installation box; several air intake fans are installed on the front side of each air intake box; a filter plate is installed on the rear side of each air intake box; a filter element is provided on each air intake box, and the filter element is located between the air intake fan and the filter plate; two guide rails for window sliding are installed on the upper side of the installation box; two folding baffles are provided inside the installation box to change the air intake area in accordance with the window; a sponge brush for cleaning and removing dust from the back of the filter plate is installed on the opposite side of each of the two folding baffles; the opposite ends of the two folding baffles are connected to the windows on the corresponding sides; a through groove is provided between the two guide rails on the installation box.

[0005] To further explain, the mounting box has a slanted groove on the rear side of the folding baffle.

[0006] To further explain, each air intake box has two sliders symmetrically arranged on both the left and right sides, and the inner side of the mounting box has corresponding grooves.

[0007] To further explain, each guide rail has several downward-sloping grooves on its underside.

[0008] Further explanation: The system also includes a cleaning assembly, comprising an exhaust box, exhaust fans, a wind deflector, a window frame, a windproof roller shutter, an electric slider, elastic elements, and a sponge. The exhaust box is installed on the upper wall of the window. Several horizontally arrayed exhaust fans are mounted on the exhaust box. A wind deflector is installed on the upper side of the exhaust box to guide the exhaust air downwards. Two window frames are symmetrically installed on the left and right sides of the window. A windproof roller shutter is installed inside the exhaust box. An electric slider is installed between the two window frames. Each of the two window frames has a groove on its facing side to cooperate with the electric slider. Several elastic elements are horizontally arrayed on the electric slider. All elastic elements are divided into two groups, each group connected to a sponge for cleaning the outside of the window. Several water spray nozzles are horizontally arrayed on the exhaust box.

[0009] To further explain, the exhaust box is equipped with a deflector to guide the water flow from the sprinkler heads toward the outside of the window.

[0010] To further explain, an inclined baffle is fixed to the mounting box.

[0011] To further clarify, the longitudinal section of the windshield is L-shaped.

[0012] To further explain, the lower side of the deflector is tilted towards the window.

[0013] To further explain, the sloping baffle is tilted downwards toward the window.

[0014] The beneficial effects of the present invention are as follows: When the window is fully opened, the corresponding folding baffle is fully unfolded, covering the filter plate on the front side of the folding baffle, so that the contact area between the filter plate and the air is minimized, thereby minimizing the air intake of the corresponding air intake box, and realizing automatic adjustment of gas flow according to different ventilation needs. When the folding baffle is unfolded, the sponge brush on the folding baffle moves horizontally in sync with the window, wiping away and cleaning the dust accumulated on the back of the filter plate. Water accumulated under the window will enter the installation box through the through groove and the strip groove on the guide rail, flush and clean the filter plate, and then be discharged out through the inclined groove. The electric slider moves downward through the groove on the window frame, and at the same time, it drives the sponge to move downward in sync with the electric slider to wipe and clean the window; By unfolding the windproof roller shutter, the indoor air exhausted by the exhaust fan is blown along the windproof roller shutter towards the lower side of the window, blowing the dust and other pollutants accumulated on the lower side of the window into the installation box, and the dust is adsorbed onto the filter plate by the intake fan. The airflow guide of the wind deflector allows the air exhausted by the exhaust fan to move downwards along the inside of the wind deflector, blowing away the dust adhering to the outside of the unfolded windproof roller shutter and preventing contamination of the windproof roller shutter after it is rolled up.

Detailed Implementation

[0017] The invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are illustrated. However, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0018] Example 1: An air purifier for public places with intelligent switching of working modes, such as Figures 1-7 As shown, it includes a mounting box 101; It also includes an air intake box 102, an air intake fan 103, a filter plate 104, a filter element 105, a guide rail 106, a folding baffle 107, and a sponge brush 108; an installation box 101 is installed on the lower wall of window 1; two air intake boxes 102 are symmetrically arranged on the left and right sides of the installation box 101; several air intake fans 103 are installed on the front side of each air intake box 102; a filter plate 104 is installed on the rear side of each air intake box 102; a filter element 105 is provided on each air intake box 102, and the filter element 105 is located between the air intake fan 103 and the filter plate 104; two guide rails 106 are installed on the upper side of the installation box 101; two folding baffles 107 are provided inside the installation box 101; a sponge brush 108 is installed on the opposite side of each of the two folding baffles 107; the opposite ends of the two folding baffles 107 are connected to the corresponding side of window 1; a through groove 10101 is provided between the two guide rails 106 on the installation box 101.

[0019] The mounting box 101 has a slanted groove 10102 on the rear side of the folding baffle 107, which allows rainwater and dust brushed off by the sponge 208 to be discharged from the mounting box 101.

[0020] Each air intake box 102 has two sliders symmetrically arranged on its left and right sides, and the inner side of the mounting box 101 has corresponding sliding grooves, which ensures that the air intake box 102 can be pulled out freely, meeting the convenient needs of cleaning and replacing the filter element 105.

[0021] Each guide rail 106 has several downward-sloping grooves on its underside to drain rainwater and dust from the underside of window 1.

[0022] To face Figure 1 Based on the current technology, wall-mounted air purifiers are commonly used to purify indoor air in public places. However, these purifiers filter and circulate indoor air, resulting in poor air circulation between indoors and outdoors. Given the risk of germ transmission in public places, indoor air circulation and filtration cannot prevent the spread of germs. Furthermore, existing window-type air purifiers cannot meet the ventilation requirements of public places and cannot adjust the ventilation volume according to needs. In addition, replacing the filter element 105 in existing window-type air purifiers requires disassembly and reassembly, which is difficult and time-consuming.

[0023] To solve the above problems, an installation box 101 is installed on the lower wall of window 1. All suction fans 103 are activated. By closing window 1 to isolate indoor and outdoor air circulation, outdoor air is forced to move into the room through the suction box 102, passing through the filter plate 104 and filter element 105 for purification before entering the room, providing purified fresh air for the indoor environment. When both windows 1 are closed, both folding baffles 107 are folded to their minimum position, maximizing the contact area between the filter plate 104 and the air, thus maximizing the suction capacity of the suction box 102 to meet the ventilation requirements when window 1 is fully closed. When window 1 needs to be opened, outdoor air can enter the room through the open window 1, reducing the ventilation requirement. When window 1 is pushed open, it moves laterally along the corresponding guide rail 106. Simultaneously, the window 1 drives the corresponding folding baffle 107 to unfold in the direction of movement. When the window 1 is fully opened, the corresponding folding baffle 107 is fully unfolded, covering the filter plate 104 on the front side of the folding baffle 107, so that the contact area between the filter plate 104 and the air is minimized, thereby minimizing the air intake of the corresponding air intake box 102. This meets the change in air exchange demand after the window 1 is opened, and realizes the change in air intake of the air intake box 102 according to the air exchange demand when opening and closing the window. At the same time, when the folding baffle 107 unfolds, the sponge brush 108 on the folding baffle 107 wipes and cleans the dust accumulated on the back side of the filter plate 104 while moving horizontally in sync with the window 1. The cleaned contaminants fall outward along the inclined groove 10102 for removal, reducing the burden of subsequent cleaning and maintenance.

[0024] Meanwhile, when encountering heavy rain, the water accumulated on the lower side of window 1 will enter the installation box 101 through the through groove 10101 and the strip groove on the guide rail 106, flush and clean the filter plate 104, and then be discharged outward through the inclined groove 10102, thereby achieving further cleaning of the filter plate 104 and completing the removal of water accumulated on the lower side of window 1.

[0025] Example 2: Based on Example 1, such as Figures 8-12As shown, it also includes a cleaning assembly, which includes an exhaust box 201, an exhaust fan 202, a wind deflector 203, a window frame 204, a windproof roller shutter 205, an electric slider 206, an elastic element 207, and a sponge 208; the exhaust box 201 is installed on the upper wall of window 1; several horizontally arrayed exhaust fans 202 are installed on the exhaust box 201; a wind deflector 203 is provided on the upper side of the exhaust box 201; two window frames 204 are symmetrically installed on the left and right sides of window 1; the exhaust box 204... 1. An internal windproof roller shutter 205 is installed; an electric slider 206 is installed between two window frames 204; each of the two window frames 204 has a groove on its facing side that cooperates with the electric slider 206; several elastic elements 207 are horizontally arranged on the electric slider 206; the elastic elements 207 are spring telescopic rods; all the elastic elements 207 are divided into two groups, and each group of elastic elements 207 is connected to a sponge 208; several sprinkler heads 209 are horizontally arranged on the exhaust box 201.

[0026] A baffle plate 2010 is installed on the exhaust box 201.

[0027] An inclined baffle 2011 is fixedly connected to the mounting box 101.

[0028] The longitudinal section of the windshield cover 203 is L-shaped.

[0029] The lower side of the baffle 2010 is tilted toward window 1 to ensure that the water sprayed from the sprinkler head 209 flows toward the glass.

[0030] The inclined baffle 2011 tilts downward toward window 1, so as to guide rainwater or cleaned sewage through the channel 10101 and the strip channel on the guide rail 106 for discharge.

[0031] In the existing technology, the air intake and exhaust design of window air purifiers are integrated, resulting in low air purification efficiency and air exchange rate. At the same time, it is difficult to clean the outside of window 1, and existing window air purifiers are easily affected by extreme weather conditions, failing to effectively protect window 1.

[0032] To solve the above problems, an exhaust box 201 is installed on the upper side of window 1 to separate the intake and exhaust functions. When all exhaust fans 202 are started, indoor air is exhausted to the outside through the exhaust box 201. Combined with the intake box 102, this achieves air circulation between indoors and outdoors. When cleaning the outside of window 1 is required, water is sprayed from the sprinkler head 209 and guided downwards by the guide baffle 2010, spraying water onto the outside of window 1. Then, the electric slider 206 moves downwards through the sliding groove on the window frame 204, simultaneously driving the sponge 208 to follow the electric slider 206 downwards to wipe and clean window 1. During cleaning, the inclined baffle 2011 guides the cleaned water flow through the through groove 10101 and the strip groove on the guide rail 106 into the mounting box 101. During cleaning, the elastic element 207 ensures that the sponge 208 remains stably attached to the outside of window 1 during its downward movement. As the electric slider 206 moves downwards, the windproof roller shutter... 205 and 206 move downward together, causing the windproof roller shutter 205 to unfold and form a windbreak. While protecting the window 1 in extreme weather, the unfolded windproof roller shutter 205 allows indoor air exhausted by the exhaust fan 202 to be blown towards the lower side of the window 1. This blows dust and other pollutants accumulated on the lower side of the window 1 into the mounting box 101 through the through groove 10101 and the strip groove on the guide rail 106. The suction fan 103 then causes the dust to be adsorbed onto the filter plate 104. The system further cleans window 1. When cleaning is complete, the electric slider 206 is controlled to move upward, allowing the sponge to return to its original position. The exhaust fan 202 then dries the moisture, improving the lifespan of the sponge. As the electric slider 206 moves upward, the airflow is guided by the wind deflector 203, causing the air exhausted by the exhaust fan 202 to move downward along the inside of the wind deflector 203, blowing away the dust adhering to the outside of the unfolded windproof roller shutter 205 and preventing contamination of the windproof roller shutter 205 after it is rolled up.

[0033] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
