Description

Technical Field

[0001] This utility model relates to the field of air purification technology, and in particular to a smoke-removing air purifier. Background Technology

[0002] With the improvement of people's living standards and the increasing requirements for indoor air quality, smoke-removing air purifiers have gradually become common equipment in homes and offices. Existing smoke-removing air purifiers mainly remove smoke particles and harmful gases from the air through multi-layer filtration systems. Their core components include a pre-filter, a high-efficiency filter (such as a HEPA filter), and an activated carbon filter layer. However, existing technologies still have some shortcomings in practical applications.

[0003] Traditional smoke-removing air purifiers have limited filtration efficiency, especially in removing ultrafine particles (such as PM2.5 and smaller). While existing HEPA filters can effectively remove particles with a diameter of 0.3 micrometers or larger, their filtration effect on smaller particles is not ideal. This results in air purifiers failing to quickly and effectively purify the air in environments with poor air quality or high smoke concentrations, thus failing to meet people's higher demands for a healthy breathing environment. Furthermore, the structural design of existing smoke-removing air purifiers is not ideal, making filter replacement and maintenance inconvenient. In some devices, the filter is installed inside a difficult-to-remove casing, requiring users to disassemble the entire casing to replace the filter, a complex, time-consuming, and laborious process. Utility Model Content

[0004] The purpose of this invention is to provide a smoke-removing air purifier to solve the problem that existing technologies are unable to quickly and effectively purify the air in situations with high smoke concentrations.

A main air intake component and an auxiliary air intake component are respectively located at the front end of the main air duct and the auxiliary air duct. A pre-filter component is located at the rear end of the main air intake component. An activated carbon filter layer and a second high-efficiency filter layer are sequentially arranged at the rear end of the pre-filter component. A control mechanism, a drive component, and a sensing device are also located at the rear end of the second high-efficiency filter layer. The end of the auxiliary air duct is directly connected to the activated carbon filter layer. The control mechanism is electrically connected to the main air intake component, the auxiliary air intake component, the drive mechanism, and the sensing device.

[0007] Furthermore, the primary air purification component includes: a primary filter screen disposed inside the air intake grille, a first high-efficiency filter screen disposed behind the primary filter screen, and a nanomaterial composite filter screen disposed behind the first high-efficiency filter screen.

[0008] Furthermore, the lower end of the air intake grille is provided with an air intake mesh, and the rear end of the air intake mesh is connected to an auxiliary air duct.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0020] See Figures 1 to 3 This utility model provides a smoke-removing air purifier for indoor air purification. The outer shell 1 has a rectangular tetrahedral structure with interconnected openings at both ends to form the main structure of the air purifier, providing installation space and support for internal components. An air intake grille 2 and an exhaust grille 22 are respectively located at the openings at both ends. The lower end of the air intake grille 2 is a mesh air intake screen to assist the air duct in quickly drawing in air. The exhaust grille 22 serves as the purifier's exhaust structure and is located at the right end opening of the outer shell 1. The air duct is divided into a main air duct and an auxiliary air duct by a partition plate. The air duct has a main air duct and auxiliary air duct cross-sectional area ratio of 3:1. The primary air purification component 3 is installed in the main air duct at the rear end of the air intake grille 2. The primary air purification component 3 includes: a primary filter 31 installed at the rear end of the air intake grille 2 for preliminary filtration of impurities, serving as the first filtration barrier to remove large particulate pollutants in the air; a first high-efficiency filter layer 32 installed at the rear end of the primary filter 31 for further removal of fine particulate matter in the air; and a nanomaterial composite filter 33 installed behind the first high-efficiency filter layer 32 for capturing ultrafine particulate matter and harmful substances.

[0021] An activated carbon filter layer 5 is located at the rear end of the nanomaterial composite filter 33. It utilizes the adsorption properties of activated carbon to remove harmful gases such as benzene, formaldehyde, and ammonia, as well as odors and some volatile organic compounds from the smoke. A second high-efficiency filter unit is located at the rear end of the activated carbon filter layer 5, providing final purification of the air after the previous layers, further removing residual fine particulate matter. A control mechanism is located at the rear end of the second high-efficiency filter layer 6. The control mechanism is electrically connected to the drive mechanism 7, control panel, and suction assembly. It receives monitoring data from the air quality sensor, automatically adjusts the fan speed and filter status according to air quality to achieve intelligent control, and controls the current status of the device via the control panel. The drive mechanism 7 generates airflow by rotating, drawing indoor air into the purifier and expelling the purified air. Its speed can be adjusted according to the instructions of the control mechanism to adapt to different purification needs and energy-saving requirements.

[0022] In actual use, after connecting the power, the operating panel is used to select the working mode. The purifier detects the air quality through the sensor in the sensing device 8, and at the same time, it detects whether the indoor smoke concentration has reached the threshold through the smoke concentration sensor in the sensing device 8. When the smoke concentration has not reached the threshold, the control mechanism controls the switching mechanism to block the auxiliary air duct. The indoor air enters the main air duct through the air intake grille 2 and the main air intake component 4 for air purification. Then, it passes through the pre-filter to remove fine particulate matter in the air, and then passes through the first high-efficiency filter layer and the nano-material composite filter 33 to further remove harmful substances and ultrafine particulate matter in the air. Then, it passes through the activated carbon filter layer 5 to adsorb harmful gases. Finally, after deep purification by the second high-efficiency filter, it is discharged through the exhaust grille 22, completing the purification of indoor air and ensuring fresh indoor air. When the sensor 8 detects that the smoke concentration has reached the threshold, the control mechanism automatically opens the auxiliary air duct through the control switching structure, so that the air is preferentially introduced into the purifier through the auxiliary air intake component 41 and the auxiliary air duct. The air then enters the activated carbon filter layer 5 directly through the auxiliary air duct for rapid adsorption, and then passes through the second high-efficiency filter for deep purification, which quickly reduces the smoke concentration and ensures that the indoor air quality is quickly restored, thus achieving the function of quickly removing indoor smoke.

[0023] The beneficial effects of this invention are as follows: Through multi-layer filtration and a dual-air duct design, air purification efficiency is effectively improved, especially when indoor smoke concentration is high. Operation is convenient; the control panel allows users to start and stop the unit with a single button, adjust the fan speed flexibly with the fan speed adjustment button, and monitor the indoor smoke concentration in real time through a smoke concentration sensor within the sensing device 8. The control mechanism intelligently adjusts the working mode to achieve rapid smoke removal and air purification. Furthermore, one side of the right side panel of the outer casing 1 is detachable, facilitating quick filter replacement, reducing bacterial growth, and increasing filter lifespan.

[0024] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
