Description

Technical Field

[0001] This application relates to the field of smart home appliance technology, such as a disinfection machine for entryways. Background Technology

[0002] Currently, the entryway is a crucial space connecting the indoor and outdoor environments. This space is easily affected by external environmental factors, such as the intrusion of cold (or warm) air, dust, flies and mosquitoes, bacteria and viruses, and unpleasant odors. When users open the door to enter their homes, they bring these harmful substances into the house.

[0003] A related technology discloses an air curtain machine, which is installed at the entrance hall to form an air curtain. When the user opens the entrance door, it can block the outdoor environment and prevent the intrusion of cold air (or hot air), dust, flying insects such as flies and mosquitoes, bacteria, viruses, and odors. However, since users may carry some bacteria and viruses when entering the house from the outside, and the entrance hall is where users change shoes, clothes, and place garbage and debris, bacteria can easily grow. Under the blowing of the air curtain, viruses and bacteria may spread rapidly, affecting the user's health.

[0004] It is evident that preventing the spread of bacteria and viruses that could affect users' health when using air curtain machines has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0006] This disclosure provides an entryway disinfection machine. The disinfectant emitted by the disinfection component spreads in the entryway with the airflow brought up by the air curtain, effectively inactivating bacteria or viruses in the entryway and preventing their spread, thus better protecting the user's health.

[0007] In some embodiments, the entryway disinfection machine includes: a housing, a fan, and a disinfection component. The housing defines an internal space, and an elongated air outlet and a disinfection port are provided on the lower side of the housing, wherein the air outlet and the disinfection port are arranged sequentially along the direction from the entrance door towards the interior; the fan is located within the internal space, and its air outlet is connected to the air outlet; the disinfection component is located within the internal space, and the disinfection component is connected to the disinfection port.

[0008] The entryway disinfection machine provided in this embodiment can achieve the following technical effects:

[0009] The system is equipped with a fan and a disinfection component. The fan blows air out through a long, narrow nozzle, forming an air curtain to isolate the outdoor environment and prevent outdoor temperatures, dust, insects, and bacteria from entering the room. The air curtain also blows off dust and bacteria from the user's clothing. The disinfection component, positioned on the side of the air curtain facing inwards, inactivates bacteria and viruses stirred up by the air curtain. Since the entryway is typically where users change clothes, shoes, and dispose of trash, it is prone to bacterial or viral growth. The disinfectant emitted by the disinfection component spreads throughout the entryway with the airflow from the air curtain, effectively inactivating bacteria and viruses in the entryway and preventing their spread, thus better protecting the user's health.

[0034] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0035] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0036] Combination Figure 1As shown in the figure, this embodiment of the present disclosure provides a foyer disinfection machine, which includes: a housing 100, a fan 200, and a disinfection component 300. The housing 100 defines an internal space, and an elongated air outlet 201 and a disinfection outlet 301 are provided on the lower side of the housing 100, wherein the air outlet 201 and the disinfection outlet 301 are arranged sequentially along the direction from the entrance door towards the interior; the fan 200 is located in the internal space, and its air outlet is connected to the air outlet 201; the disinfection component 300 is located in the internal space, and the disinfection component 300 is connected to the disinfection outlet 301.

[0037] The entryway disinfection machine provided in this embodiment includes a fan 200 and a disinfection component 300. The fan 200 blows air out through a long, narrow nozzle 201, forming an air curtain to isolate the outdoor environment and prevent outdoor temperature, dust, insects, bacteria, etc., from entering the room. The air curtain also blows off dust and bacteria from the user's body. The disinfection component 300, positioned on the side of the air curtain facing the room, inactivates bacteria and viruses stirred up by the air curtain. Since the entryway is typically where users change clothes, shoes, and dispose of trash, it is prone to bacterial or viral growth. The disinfectant emitted by the disinfection component 300 spreads throughout the entryway with the airflow from the air curtain, effectively inactivating bacteria and viruses and preventing their spread, thus better protecting the user's health.

[0038] Optionally, multiple disinfection ports 301 are provided, and the multiple disinfection ports 301 are arranged in an arc shape. In this way, by setting multiple disinfection ports 301 and arranging the disinfection ports 301 in an arc shape, the area of ​​the disinfection port 301 for discharging disinfectant is increased, thereby allowing the disinfectant to be better dispersed and fully contact the airflow in the entrance hall, thus improving disinfection efficiency.

[0039] Optionally, some of the multiple disinfection nozzles 301 are vertically oriented downwards, while the rest are inclined downwards. This allows the sprayed disinfectant to sterilize the area below, and the inclined nozzles 301 can also be offset to one side to spray the disinfectant, allowing it to spread better into the entryway and expanding the disinfection range.

[0040] Optionally, a lighting area 400 is provided on one side of the disinfection port 301. In this way, the lighting area 400 can serve as an entryway light to illuminate the entryway, and by placing the lighting area 400 on one side of the disinfection port 301, the disinfectant discharged from the disinfection port 301 is more clearly illuminated by the lighting area 400, allowing users to more intuitively understand the working status of the disinfection component 300.

[0041] Optionally, the lighting area 400 is an LED light, and the lighting area 400 is tilted towards the side where the disinfection port 301 is located. In this way, the LED light consumes less energy and has a better illumination effect. When it is tilted at a certain angle towards the disinfection port 301, it can better illuminate the spray from the disinfection port 301, thereby improving the display effect of the disinfection spray.

[0042] like Figure 2 As shown, optionally, the disinfection component 300 includes: a charged spray water tank 302 and a charged nozzle 303. The charged spray water tank 302 is used to store water; the charged nozzle 303 is connected to the charged spray water tank 302 and is used to generate negatively charged water mist. In this way, the charged nozzle 303 can atomize the water in the charged spray water tank 302 and make it negatively charged. The charged water mist can inactivate bacteria or viruses that come into contact with the water mist or adsorb dust and impurities in the air, thereby disinfecting the entryway and adsorbing dust and impurities, keeping the entryway clean.

[0043] Optionally, multiple charged nozzles 303 are provided, and each charged nozzle 303 is correspondingly disposed in a disinfection port 301. In this way, by setting multiple charged nozzles 303 to spray disinfectant from different disinfection ports 301, viruses and bacteria can be killed more comprehensively.

[0044] Optionally, multiple charged nozzles 303 are connected to the same charged spray water tank 302, or the charged spray water tank 302 is provided with multiple one-charge nozzles corresponding to one charged spray water tank 302. Alternatively, one charged spray water tank 302 can correspond to two charged nozzles. In this way, multiple charged nozzles 303 sharing one charged spray water tank 302 can reduce the number of charged spray water tanks 302 used, simplify the installation structure, and make it more convenient to add water to the charged spray water tank 302.

[0045] like Figure 3 As shown, optionally, the charged nozzle 303 includes an atomizing component 304 and an annular electrode 305. The atomizing component 304 is used to atomize water; the annular electrode 305 is used to generate an electric field, causing the water mist to become charged. Thus, when the micron-sized water mist generated by the atomizing component 304 passes through the middle region of the annular electrode 305, the positive charges in the water mist are repelled due to the repulsion of like charges. Therefore, the surface of the sprayed water mist carries a negative charge. This negatively charged water mist can kill bacteria and viruses in the entryway environment and on the user's body, and can also adsorb dust and other impurities, making them easier to collect and clean, thus keeping the entryway clean.

[0046] Optionally, the atomizing component 304 is an ultrasonic atomizing plate. In this way, using an ultrasonic atomizing plate to atomize the flowing water results in better atomization effect, producing micron-sized water mist, which facilitates the charging of small water particles at the annular electrode 305.

[0047] Optionally, the annular electrode 305 is connected to a positive high-voltage transformer. This generates a positive high-voltage electric field in the annular electrode 305, which repels positively charged ions in the water mist, causing the water mist to become negatively charged. Negatively charged ions have a strong bactericidal and disinfecting effect, thereby improving the inactivation effect on bacteria and viruses.

[0048] Optionally, the charged nozzle 303 also includes a grounding wire 306, which is connected to the middle region of the annular electrode 305. This allows positively charged ions repelled by the positive high-voltage electric field to be discharged through the grounding wire 306, thus protecting the sprayed water mist from the influence of positively charged ions and ensuring it carries a stable negative charge.

[0049] Optionally, multiple annular electrodes 305 are provided, and the radii of the multiple annular electrodes 305 are different. Thus, when connected to the same voltage source, the different radii of the annular electrodes 305 result in different electric field strengths. The smaller the radius of the annular electrode 305, the stronger the electric field. Therefore, when using a small atomization volume and a small-radius annular electrode 305, the fine water mist will decompose into a large number of reactive oxygen ions such as hydroxyl radicals under the action of a strong electric field. This can kill bacteria on the surface or render bacteria inactive. Simultaneously, its oxidizing properties can also decompose odor components (organic matter), thereby achieving sterilization and deodorization effects. Conversely, when using a large atomization volume and a large-radius annular electrode 305, the weak electric field can only cause the surface charge of the water mist to accumulate but not decompose. In this case, it can adsorb dust, PM2.5, and other particulate matter, cleaning the air. Therefore, by providing multiple annular electrodes 305 with different radii, different radii of annular electrodes 305 can be selected for activation according to needs, so that the output water mist can sterilize and disinfect while also adsorbing dust, PM2.5, and other particulate matter, making the overall function of the disinfection component 300 more powerful.

[0050] Optionally, multiple ring electrodes 305 are connected to the same positive high-voltage transformer. This allows the multiple ring electrodes 305 to be powered by the same positive high-voltage transformer, improving the stability of the power supply to the multiple ring electrodes 305, ensuring consistent connection voltages, simplifying the structure, and reducing overall cost.

[0051] Optionally, multiple annular electrodes 305 are connected to a positive high-voltage transformer via a switching switch. This allows the multiple annular electrodes 305 to work alternately via the switching switch, generating different types of disinfectant water mist. This ensures the water mist has both adsorption and sterilization effects, better treating the environment and maintaining air quality in the entryway.

[0052] Optionally, two annular electrodes 305 are provided, and the radius of one annular electrode 305 is half the radius of the other annular electrode 305. In this way, the smaller the radius of the annular electrode 305, the greater the electric field strength it generates. By setting the radius of one annular electrode 305 to half the radius of the other annular electrode 305, one annular electrode 305 can generate a strong electric field and the other a weak electric field. With the alternating operation of the two annular electrodes 305, water mist particles with good bactericidal effect and water mist particles with good adsorption effect can be generated.

[0053] Optionally, the charged nozzle 303 also includes a water flow channel 307. Both the atomizing component 304 and the annular electrode 305 are disposed within the water flow channel 307, with the atomizing component 304 positioned upstream of the annular electrode 305. Thus, after water from the charged spray tank 302 enters the water flow channel 307, it is first atomized at the atomizing component 304 to generate water mist. The water mist then passes through the annular electrode 305, where it becomes charged under the electric field generated by the annular electrode 305. Since water mist is composed of water particles, it is more easily charged under the influence of the electric field. Therefore, positioning the atomizing component 304 upstream of the annular electrode 305 allows the water to be atomized before entering the electric field, improving the uniformity of the water mist's charge and thus enhancing the sterilization and disinfection properties or adsorption capacity of the resulting water mist.

[0054] Optionally, the annular electrode 305 with a smaller radius is positioned upstream of the annular electrode 305 with a larger radius. In this way, since water disperses after atomization, positioning the annular electrode 305 with a smaller radius upstream facilitates the dispersion of the water mist passing through the annular electrode 305, resulting in a sparser and more uniform distribution of water droplets in the water mist, which is more conducive to the charging of water droplets.

[0055] like Figure 4 As shown, optionally, the entryway disinfection machine also includes an aromatherapy spray assembly 500. The aromatherapy spray assembly 500 is located inside the housing 100 and has an aromatherapy outlet connecting to the outside of the housing 100. Thus, since entryways often contain items that easily generate odors, such as shoe cabinets and trash cans, the aromatherapy spray assembly 500 can produce an aromatherapy spray to mask other odors in the entryway, thereby making the air in the entryway fresher.

[0056] like Figure 5 , 6As shown, optionally, the aromatherapy assembly includes: a movable plate 501, a spray assembly 502, and an aromatherapy box 503. The movable plate 501 is movably connected to the housing 100 and can be folded or detached relative to the housing 100; the spray assembly 502 is fixedly mounted on the movable plate 501; the aromatherapy box 503 is movably connected to the spray assembly 502 and is used to provide aromatherapy liquid to the spray assembly 502. In this way, the entire aromatherapy assembly can be detached from the housing 100 by folding or detaching, exposing the aromatherapy box 503. When the aromatherapy liquid in the aromatherapy box 503 is insufficient, it can be exposed and detached from the spray assembly 502 to replace or add aromatherapy liquid, improving the convenience of replacing or adding aromatherapy liquid to the aromatherapy box 503.

[0057] Optionally, the bottom of the housing 100 is provided with a replacement port, and a movable plate 501 is movably covered by the replacement port. In this way, the aromatherapy component can be removed from inside the housing 100 through the replacement port, making it convenient to replace the aromatherapy in the aromatherapy component.

[0058] Optionally, the movable plate 501 is rotatably connected to one side of the replacement port, and the other end of the movable plate 501 is provided with a self-locking mechanism that can lock or unlock it with the housing 100. In this way, the movable plate 501 can be locked, making the movable plate 501 more stable when covering the replacement port.

[0059] Optionally, the spray assembly 502 includes an electric spray head 504 and a connector 505, with a liquid inlet in the connector 505, and the aromatherapy box 503 is installed inside the connector 505. In this way, the electric spray head 504 provides a more even spray, and the active spraying facilitates the diffusion of the aromatherapy within the aromatherapy box 503, quickly improving the odor in the entryway and maintaining clean air.

[0060] Optionally, the aroma diffuser box 503 and the connector 505 are connected by a plug-in connection. A sealing ring is also provided between the aroma diffuser box 503 and the connector 505. This ensures a proper seal between the aroma diffuser box 503 and the electric spray head 504 during disassembly and assembly, preventing leakage.

[0061] Optionally, the disinfection component 300 is also mounted on the movable plate 501 and can be moved out of the housing 100 along with the movable plate 501. This facilitates the addition of water to the charged spray water tank 302 in the disinfection component 300, improving ease of use.

[0062] Combination Figure 7As shown, in some optional embodiments, the entryway disinfection machine also includes a display screen 600. The display screen 600 is mounted on the housing 100 and is used to display one or more of the following: time, weather, news, outside image, and surveillance image. Thus, by setting up the display screen 600, information such as date, current time, real-time weather forecast, outdoor air quality, and today's news can be displayed. Users can see this information before leaving home to manage their time, decide whether to bring an umbrella, or add clothing, thus improving the user experience. Additionally, the LCD display screen 600 can also connect to a smart doorbell or surveillance camera via wireless communication (Bluetooth, etc.) to display outside surveillance images. Users can see visitors from a distance without having to go to the door.

[0063] Optionally, the display screen 600 includes a network connection module for connecting to a home network, enabling it to obtain real-time weather forecasts, outdoor air quality, and today's news. This network connection allows for real-time information updates on the display screen 600, ensuring timely information delivery and providing effective notifications for users, while making full use of the time users spend changing clothes and shoes in the entryway.

[0064] Optionally, the display screen 600 can also display the working status of the entryway disinfection machine itself, such as the airflow level of the air curtain, the remaining amount of aromatherapy in the aromatherapy box 503, and the remaining water in the charged spray water tank 302. The remaining amount of aromatherapy in the aromatherapy box 503 and the remaining water in the charged spray water tank 302 can be obtained through level sensors located inside the aromatherapy box 503 and the charged spray water tank 302, or through weight sensors located on the lower side of the aromatherapy box 503 and the lower side of the charged spray water tank 302. This allows for intelligent indication of the remaining amount of aromatherapy or spray water, providing convenient reminders to the user and improving the intuitiveness of use.

[0065] Optionally, the display screen 600 is a single, integrated LCD screen embedded in the front of the housing 100 facing the interior. The display screen 600 is tilted at a downward angle towards the entrance door. This allows users to easily look up when standing at the doorway. The tilt angle is greater than or equal to 10 degrees and less than or equal to 30 degrees, preferably 20 degrees.

[0066] like Figure 8-12 As shown, in some embodiments, the entryway disinfection machine further includes an air inlet duct 700. One end of the air inlet duct 700 extends into the internal space, and the other end is provided with a dust suction unit 701 and extends downward toward the housing 100. In this way, by utilizing the air inlet ducts 700 provided on both sides of the door frame and equipped with the dust suction unit 701, dust and germs that are raised can be adsorbed and collected, preventing dust and germs from being raised and improving the air cleanliness of the entryway.

[0067] Optionally, the suction unit 701 includes a perforated tube 702 and a filter assembly 703. The upper end of the perforated tube 702 is connected to the air inlet duct 700; the filter assembly 703 is disposed at the connection between the perforated tube 702 and the air inlet duct 700. In this way, air can be drawn in more effectively through the perforated tube 702, and the filter assembly 703 filters the drawn-in airflow, forming an air curtain using the circulating airflow, and better filtering inhaled dust and germs, thereby improving the cleanliness of the air curtain airflow.

[0068] Optionally, the length of the perforated tube 702 is greater than or equal to one-tenth of the total length of the air inlet tube 700, and less than or equal to one-fifth of the total length of the air inlet tube 700. Limiting the length of the perforated tube 702 within this range prevents the suction pressure from decreasing due to excessive length, thus affecting the suction effect on dust and other particles. It also prevents the suction position from being too high, directly absorbing the airflow blown out by the air curtain and affecting its shielding effect.

[0069] Optionally, a movable socket is provided at the junction of the perforated tube 702 and the air inlet tube 700, into which the filter assembly 703 can be movably inserted. This allows the filter assembly 703 to be disassembled and installed, facilitating cleaning or replacement and keeping it clean. This, in turn, allows for better filtration of the air drawn in by the perforated tube 702, resulting in a cleaner air curtain.

[0070] Optionally, the filter assembly 703 includes a carbon fiber filter layer and an electrostatic adsorption layer. In this way, the electrostatic adsorption layer can absorb larger dust particles and other impurities, while the carbon fiber filter layer filters smaller dust particles and other impurities, and can also adsorb some odor-producing molecules, thereby improving the air filtration effect and maintaining air cleanliness.

[0071] Optionally, the carbon fiber filter layer is disposed above the electrostatic adsorption layer. This allows the airflow to pass through the electrostatic adsorption layer first, followed by the carbon fiber filter layer. The carbon fiber filter layer first adsorbs larger dust particles, and then filters smaller dust particles and odor molecules. Since the electrostatic adsorption layer is easy to clean, while the carbon fiber filter layer is not, using electrostatic adsorption to adsorb dust particles first reduces dust accumulation on the carbon fiber filter layer and extends its service life.

[0072] Optionally, the vacuum unit 701 also includes a dust collection box 704. The dust collection box 704 is detachably disposed at the lower end of the perforated tube 702. In this way, the dust collection box 704 collects the dust, germs, etc. filtered by the filter assembly 703, preventing the filtered dust, germs, etc. from being stirred up again, causing the air in the entryway to be re-polluted.

[0073] Optionally, the dust collection box 704 has a drawer structure and is located at the bottom of the perforated tube 702, allowing it to be inserted into or pulled out of the perforated tube 702. This facilitates the installation and removal of the dust collection box 704, and allows it to be removed for cleaning when there is a lot of dust inside.

[0074] Optionally, a water-absorbing pad is provided inside the dust collection box 704. In this way, the water-absorbing pad absorbs some of the moisture, keeping the inside of the dust collection box 704 moist, which can prevent the moisture entering the dust collection box 704 from being stirred up again, improve dust collection efficiency, and the water-absorbing pad can also prevent water from being directly put into the dust collection box 704 and causing water to spill and pollute the ground.

[0075] Optionally, one end of the air inlet duct 700 extending into the internal space is opposite to but not connected to the air inlet end of the fan 200, and the housing 100 is provided with an air inlet that connects to the internal space. In this way, the fan 200 can take in air through the air inlet duct 700, and can also take in air through the air inlet on the housing 100, thereby increasing the air intake volume, ensuring a more sufficient source of air curtain, and giving the air curtain sufficient force.

[0076] Optionally, the air inlet duct 700 includes a connecting elbow 705 disposed at its upper end, one end of which extends into the internal space from the left or right side of the housing 100. In this way, the connecting elbow 705 connects the internal space and the air inlet duct 700, making the transition at the bend of the air inlet duct 700 smoother and helping to maintain the ventilation effect of the air inlet duct 700.

[0077] like Figure 12 As shown, in some embodiments, the air inlet end of the fan 200 is provided with an air collecting pipe 202, and the cross-section of the air collecting pipe 202 and the corresponding connecting elbow 705 are the same. The air collecting pipe 202 or the connecting elbow 705 is provided with a telescopic sleeve 800, which can connect or disconnect the air collecting pipe 202 and the connecting elbow 705 by telescoping. Thus, the telescopic sleeve 800 can control whether the air collecting pipe 202 and the connecting elbow 705 are directly connected. When the air collecting pipe 202 and the connecting elbow 705 are connected, the fan 200 preferentially draws air from the air inlet pipe 700, which can improve the dust collection effect of the dust collection section 701 at the lower end of the air inlet pipe 700. When the air collecting pipe 202 and the connecting elbow 705 are disconnected, the fan 200 can simultaneously draw air through the air inlet pipe 700 and the internal space, increasing the air intake volume and thus improving the blowing effect of the air curtain.

[0078] Optionally, the telescopic sleeve 800 is provided with a strip tooth 801 extending along the length of the telescopic sleeve 800. A gear 802 is provided on one side of the strip tooth 801 to mesh with the strip tooth 801, and the gear 802 is driven by a small motor 803 to drive the telescopic sleeve 800 to move. In this way, the telescopic sleeve 800 can be moved by the small motor 803, which facilitates better control of the connection or disconnection between the air collecting pipe 202 and the connecting elbow 705 by the rotation of the small motor.

[0079] Optionally, a limiting structure is provided between the telescopic sleeve 800 and the air collecting pipe 202 or the connecting elbow 705 to prevent the telescopic sleeve 800 from rotating. This allows the telescopic sleeve 800 to slide horizontally along the air collecting pipe 202 or the connecting elbow 705, preventing the telescopic sleeve 800 from rotating and disengaging from the small motor, thus affecting the driving of the telescopic sleeve 800.

[0080] Combination Figure 13 As shown, in some optional embodiments, the entrance air curtain machine further includes a detection module 900 and a controller assembly 1000. The detection module 900 is used to detect the open / closed state of the entrance door; the controller assembly 1000 is configured to control the operating state of the fan 200 according to the open / closed state of the entrance door. In this way, the fan 200 can be switched on and off by controlling the opening / closing of the entrance door, thereby opening the air curtain when the entrance door is open. This allows the air curtain to isolate cold or hot outdoor air and prevent insects, germs, dust, etc., from entering the room, thus providing better protection for the interior and maintaining the environment at the entrance.

[0081] Optionally, if two fans 200 are installed, the detection module 900 is also used to detect the user's position, and the controller component 1000 is configured to control the on / off state of the fans 200 according to the user's position. In this way, the on / off state of the two fans 200 can be controlled according to the user's position, even after the entrance door is closed, so as to better blow off dust, germs and other particulate impurities from the user's body.

[0082] Optionally, controlling the on / off state of the fans 200 based on the user's location includes: if the user is located below one fan 200, controlling that fan 200 to turn on and controlling another fan 200 to turn off. This allows the fan 200 corresponding to the user's location to turn on, while the other fan 200 turns off, enabling the air curtain to blow on the user and closing the air curtain on the other side, saving energy and avoiding unnecessary waste.

[0083] Optionally, such as Figure 14As shown, the in-home air curtain machine also includes a particle concentration detection module 1100 and a telescopic sleeve control module 1200. The particle concentration detection module 1100 is located outside the suction unit 701 and is used to detect the concentration of particles such as dust and PM2.5 in the air, and control the position of the telescopic sleeve 800 based on the particle concentration. Thus, by detecting the concentration of particulate matter in the air through the particle concentration detection module 900 and controlling the position of the telescopic sleeve 800 accordingly, the suction power of the suction unit 701 can be changed, allowing for better dust collection for different concentrations of particulate matter pollution and maintaining air cleanliness.

[0084] Optionally, controlling the position of the telescopic sleeve 800 based on particle concentration includes: when the particle concentration is greater than a set concentration value, controlling the telescopic sleeve 800 to connect the air collection pipe 202 or the connecting elbow 705; otherwise, controlling the telescopic sleeve 800 to move to one side to disconnect the air collection pipe 202 from the connecting elbow 705. Thus, when the detected particle concentration is greater than the set concentration value, it indicates that the particulate matter concentration in the air at the entrance is too high and the air is not clean enough. In this case, connecting the air collection pipe 202 to the connecting elbow 705 allows the fan 200 to preferentially draw air through the air inlet pipe, thereby improving the absorption effect of dust and other particulate matter. Conversely, when the detected particle concentration is not high, disconnecting the air collection pipe 202 from the connecting elbow 705 allows the fan 200 to directly draw air through the internal space, improving the airflow effect of the air curtain.
