Description

Technical Field

[0001] This application relates to the field of smart home appliance technology, such as an in-home air curtain machine. 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 inside. Furthermore, the entryway is where users change shoes and clothes, and place trash and other miscellaneous items, making it a breeding ground for bacteria and odors.

[0003] A related technology discloses an air curtain machine, which is installed in 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 (hot air), dust, flying insects such as flies and mosquitoes, bacteria, viruses, and odors. However, because the air curtain machine generates a strong wind, it can easily stir up dust that has accumulated on the user or near the entrance door, making the entrance hall environment dirty and difficult to clean. Furthermore, the stirred-up dust can be easily inhaled by the user, which can affect the user's health with long-term use.

[0004] It is evident that how to avoid air pollution in the entryway and improve air cleanliness after turning on the air curtain 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 in-home air curtain machine that can isolate the indoor and outdoor spaces, preventing the intrusion of cold or hot outdoor air and preventing insects, germs, dust, etc., from entering the room. The air curtain can also blow off dust and germs from users who pass through it, keeping them clean. At the same time, the air inlet pipes on both sides of the door frame are equipped with dust suction parts to absorb and collect the dust and germs that are raised, preventing them from being stirred up and improving the air cleanliness of the entrance area when using the air curtain machine.

[0007] In some embodiments, the in-home air curtain machine includes: a housing, a fan, and an air inlet duct. The housing defines an internal space, and an elongated air outlet is provided on the lower side of the housing; the fan is located within the internal space, and its air outlet is connected to the air outlet; one end of the air inlet duct extends into the internal space, and the other end is provided with a dust suction section and extends downward toward the housing.

[0008] The in-home air curtain machine provided in this embodiment can achieve the following technical effects:

[0009] An air curtain machine is installed on the top side of the entrance door, with air inlet pipes installed on both sides of the door frame. A fan generates airflow, which is then blown out from a long, narrow nozzle, forming an air curtain. This air curtain isolates the interior from the exterior, preventing the intrusion of cold or hot air from outside, and also preventing insects, germs, and dust from entering the room. Furthermore, the air curtain can blow away dust and germs from users passing through it, maintaining their cleanliness. Since the air curtain may cause dust and germs to be stirred up, the air inlet pipes on both sides of the door frame, equipped with suction sections, can absorb and collect this stirred-up dust and germs, preventing them from being stirred up again and improving the air cleanliness of the entryway when using the air curtain machine.

[0037] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0038] Combination Figure 1-7 As shown, this embodiment of the present disclosure provides an in-home air curtain machine including: a housing 100, a fan 200, and an air inlet pipe 300. The housing 100 defines an internal space, and an elongated air outlet 201 is provided on the lower side of the housing 100; the fan 200 is disposed in the internal space, and its air outlet end is connected to the air outlet 201; one end of the air inlet pipe 300 extends into the internal space, and the other end is provided with a dust suction part 301 and extends downward toward the housing 100.

[0039] The entrance air curtain machine provided in this embodiment is installed on the top side of the entrance door, and the air inlet pipes 300 are installed on both sides of the door frame. The fan 200 generates airflow, which is blown out from the elongated air outlet 201 to form an air curtain. The air curtain can isolate the indoor and outdoor areas, preventing the invasion of cold or hot outdoor air, and preventing insects, germs, dust, etc. from entering the room. The air curtain can also blow off dust and germs from users who pass through it, keeping them clean. At the same time, since the blowing of the air curtain may cause dust and germs to be stirred up, the air inlet pipes 300 on both sides of the door frame are equipped with dust suction parts 301 to absorb and collect the stirred-up dust and germs, preventing them from being stirred up and improving the air cleanliness of the entrance when using the air curtain machine.

[0040] Optionally, the fan 200 is a centrifugal fan 200, and the axial length of the centrifugal fan 200 is the same as the length of the air outlet 201. In this way, by utilizing the axial air intake and radial air outlet characteristics of the centrifugal fan 200, the airflow direction can be changed, which is convenient for installation and use. Moreover, under the condition of generating the same air pressure, the centrifugal fan 200 occupies less space. Setting the axial length of the centrifugal fan 200 to be the same as the length of the air outlet 201 can make the air outlet of the centrifugal fan 200 blown more evenly through the air outlet 201, improving the uniformity of the formed air curtain and making the air curtain form a better barrier.

[0041] Optionally, two fans 200 and two air inlet pipes 300 are provided, with the two air inlet pipes 300 respectively installed on both sides of the door frame. In this way, by using two fans 200 in conjunction with two air inlet pipes 300, and installing the two air inlet pipes 300 on both sides of the door frame, air can be drawn in from both sides of the door frame, increasing the air intake area. The two fans 200 also better form an air curtain, improving the shielding effect of the air curtain and the absorption effect of airborne dust and germs.

[0042] Optionally, the cross-section of the air inlet duct 300 is rectangular. In this way, the rectangular air inlet duct 300 can be better installed on both sides of the door frame, forming an integral whole with the door frame, resulting in a more stable structure and an aesthetically pleasing appearance.

[0043] Optionally, the air inlet duct 300 is installed at a preset distance from the ground after its bottom extension. This allows sufficient space for the suction unit 301 to be positioned close to the ground, enabling it to collect dust from the bottom. Since dust and other particulate matter are mostly distributed close to the ground, placing the suction unit 301 close to the ground allows for better collection of these particles. Furthermore, it creates a lower absorption area, preventing dust from rising, maintaining clean air above, and preventing users from inhaling excessive dust and other particulate matter, thus benefiting their health.

[0044] Optionally, the preset distance is greater than or equal to 30 cm and less than or equal to 50 cm. Preferably, the preset distance is 40 cm. In this way, the concentration of dust and other particulate matter is generally higher within a range of 30 to 50 cm from the ground, and the absorption effect of dust and other particulate matter is better at this position, which can effectively keep the air in the entryway clean.

[0045] Optionally, both fans 200 can be connected to the same motor and driven by the same motor, or the two fans 200 can be connected to different motors and controlled independently. Using the same motor to drive both fans 200 effectively reduces costs, while using different motors allows for independent control of the two fans 200 according to different situations, providing greater flexibility.

[0046] Optionally, such as Figure 1 , 5 As shown, the dust extraction unit 301 includes a perforated tube 302 and a filter assembly 303. The upper end of the perforated tube 302 is connected to the air inlet pipe 300; the filter assembly 303 is disposed at the connection between the perforated tube 302 and the air inlet pipe 300. In this way, air can be drawn in more effectively through the perforated tube 302, and the filter assembly 303 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.

[0047] Optionally, the length of the perforated tube 302 is greater than or equal to one-tenth of the total length of the air inlet tube 300, and less than or equal to one-fifth of the total length of the air inlet tube 300. Limiting the length of the perforated tube 302 within this range prevents it from becoming too long, which could reduce suction pressure and affect 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.

[0048] Optionally, the perforated tube 302 has the same cross-section as the air inlet tube 300, both being rectangular, and has through holes 304 on three sides. In this way, the perforated tube 302 can suck up dust and other particles from three sides, increasing the dust suction area and making it suitable for sucking up dust and other particles over a large area.

[0049] Optionally, the through holes 304 include multiple, and are horizontally arranged elongated structures. In this way, the through holes 304 can have sufficient air intake area to increase the air intake volume, and also have a certain coarse filtration effect.

[0050] Optionally, the height of the elongated through-hole 304 is less than or equal to 3 mm. This smaller height prevents larger foreign objects from being sucked into the perforated tube 302, which could clog the filter assembly 303 and affect the dust collection performance.

[0051] Optionally, a movable socket is provided at the junction of the perforated tube 302 and the air inlet tube 300, into which the filter assembly 303 can be movably inserted. This allows the filter assembly 303 to be disassembled and installed, facilitating cleaning or replacement, keeping the filter assembly 303 clean, and thus better filtering the air drawn in by the perforated tube 302, resulting in a cleaner air curtain.

[0052] Optionally, the filter assembly 303 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.

[0053] 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.

[0054] Optionally, the dust collection unit 301 further includes a dust collection box 305. The dust collection box 305 is detachably disposed at the lower end of the perforated tube 302. In this way, the dust collection box 305 collects the dust, germs, etc. filtered by the filter assembly 303, preventing the filtered dust, germs, etc. from being re-raised and causing the air in the entryway to be re-polluted.

[0055] Optionally, the dust collection box 305 has a drawer structure and is located at the bottom of the perforated tube 302, allowing it to be inserted into or removed from the perforated tube 302. This facilitates the installation and removal of the dust collection box 305, and allows it to be removed for cleaning when there is a lot of dust inside.

[0056] Optionally, a water-absorbing pad is provided inside the dust collection box 305. In this way, the water-absorbing pad absorbs some of the moisture, keeping the inside of the dust collection box 305 moist, which can prevent the moisture entering the dust collection box 305 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 305 and causing water to spill and pollute the ground.

[0057] Optionally, such as Figure 6 As shown, one end of the air inlet pipe 300 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 communicating with the internal space. In this way, the fan 200 can take in air through the air inlet pipe 300, 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.

[0058] Optionally, the air inlet duct 300 includes a connecting elbow 306 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 306 connects the internal space and the air inlet duct 300, making the transition at the bend of the air inlet duct 300 smoother and helping to maintain the ventilation effect of the air inlet duct 300.

[0059] like Figure 7As 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 306 are the same. The air collecting pipe 202 or the connecting elbow 306 is provided with a telescopic sleeve 400, which can connect or disconnect the air collecting pipe 202 and the connecting elbow 306 by telescoping. Thus, the telescopic sleeve 400 can control whether the air collecting pipe 202 and the connecting elbow 306 are directly connected. When the air collecting pipe 202 and the connecting elbow 306 are connected, the fan 200 preferentially draws air from the air inlet pipe 300, which can improve the dust collection effect of the dust collection section 301 at the lower end of the air inlet pipe 300. When the air collecting pipe 202 and the connecting elbow 306 are disconnected, the fan 200 can simultaneously draw air through the air inlet pipe 300 and the internal space, increasing the air intake volume and thus improving the blowing effect of the air curtain.

[0060] Optionally, the telescopic sleeve 400 is provided with a strip-shaped tooth 401 extending along the length of the telescopic sleeve 400. A gear 402 is provided on one side of the strip-shaped tooth 401 to mesh with the strip-shaped tooth 401, and the gear 402 is driven by a small motor 403 to drive the telescopic sleeve 400 to move. In this way, the telescopic sleeve 400 can be driven to move by the small motor 403, which facilitates better control of the connection or disconnection between the air collection pipe 202 and the connecting elbow 306 by the rotation of the small motor 403.

[0061] Optionally, a limiting structure is provided between the telescopic sleeve 400 and the air collecting pipe 202 or the connecting elbow 306 to prevent the telescopic sleeve 400 from rotating. This allows the telescopic sleeve 400 to slide horizontally along the air collecting pipe 202 or the connecting elbow 306, preventing the telescopic sleeve 400 from rotating and disengaging from the small motor 403, thus affecting the driving of the telescopic sleeve 400.

[0062] Combination Figure 8 As shown, in some optional embodiments, the entrance air curtain machine further includes a detection module 500 and a controller assembly 600. The detection module 500 is used to detect the open / closed state of the entrance door; the controller assembly 600 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.

[0063] Optionally, if two fans 200 are installed, the detection module 500 is also used to detect the user's position, and the controller component 600 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 are controlled according to the user's position, and the on / off state of the fans 200 can still be controlled according to the user's position after the entrance door is closed, which can better blow off dust, germs and other particulate impurities from the user's body.

[0064] 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.

[0065] Optionally, such as Figure 9 As shown, the in-home air curtain machine also includes: a particle concentration detection module 700 and a telescopic sleeve control module 800.

[0066] A particle concentration detection module 700 is located on the outside of the suction unit 301. It 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 400 based on the particle concentration. In this way, by detecting the concentration of particulate matter in the air through the particle concentration detection module 700 and controlling the position of the telescopic sleeve 400 accordingly, the suction power of the suction unit 301 can be changed. This allows for better dust collection for different concentrations of particulate matter pollution, thus maintaining clean air.

[0067] Optionally, controlling the position of the telescopic sleeve 400 based on particle concentration includes: when the particle concentration is greater than a set concentration value, controlling the telescopic sleeve 400 to connect the air collection pipe 202 or the connecting elbow 306; conversely, controlling the telescopic sleeve 400 to move to one side to disconnect the air collection pipe 202 from the connecting elbow 306. 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 306 allows the fan 200 to preferentially draw air in 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 306 allows the fan 200 to directly draw air in through the internal space, improving the air curtain's output effect.

[0068] Combination Figure 10As shown, in some optional embodiments, the entryway air curtain unit further includes an aromatherapy spray assembly 900. The aromatherapy spray assembly 900 is disposed inside the housing 100 and has an aromatherapy outlet communicating with 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 900 can produce aromatherapy spray to mask other odors in the entryway, thereby making the air in the entryway fresher.

[0069] Optionally, the aromatherapy assembly includes: a movable plate 901, a spray assembly 902, and an aromatherapy box 903. The movable plate 901 is movably connected to the housing 100 and can be folded or detached relative to the housing 100; the spray assembly 902 is fixedly mounted on the movable plate 901; the aromatherapy box 903 is movably connected to the spray assembly 902 and is used to provide aromatherapy liquid to the spray assembly 902. In this way, the entire aromatherapy assembly can be detached from the housing 100 by folding or disassembling, exposing the aromatherapy box 903. When the aromatherapy liquid in the aromatherapy box 903 is insufficient, it can be exposed and detached from the spray assembly 902 for replacement or addition of aromatherapy, improving the convenience of replacing or adding aromatherapy liquid to the aromatherapy box 903.

[0070] Optionally, the bottom of the housing 100 is provided with a replacement port, and the movable plate 901 movably covers 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.

[0071] Optionally, the movable plate 901 is rotatably connected to one side of the replacement port, and the other end of the movable plate 901 is provided with a self-locking mechanism, which can lock or unlock it with the housing 100. In this way, the movable plate 901 can be locked, making the movable plate 901 more stable when covering the replacement port.

[0072] Optionally, such as Figure 11 As shown, the spray assembly 902 includes an electric spray head 904 and a connector 905, with a liquid inlet hole inside the connector 905. The aromatherapy box 903 is installed inside the connector 905. Thus, using the electric spray head 904 for spraying results in a more even spray, and the active spraying facilitates the diffusion of the aromatherapy within the aromatherapy box 903, quickly improving the odor in the entryway and maintaining air cleanliness.

[0073] Optionally, the aroma diffuser box 903 and the connector 905 are connected by a plug-in connection. A sealing ring is also provided between the aroma diffuser box 903 and the connector 905. This ensures a proper seal between the aroma diffuser box 903 and the electric spray head 904 during disassembly and assembly, preventing leakage.

[0074] Optionally, the aromatherapy outlet is located on the side of the air outlet 201 furthest from the entrance door. This placement of the aromatherapy outlet on the side of the air outlet furthest from the entrance door allows for better release of the aromatherapy into the entryway, thereby neutralizing any odors in the entryway and improving air freshness.

[0075] Combination Figure 12-16 As shown, in some optional embodiments, the entrance air curtain machine further includes a disinfection component 1000. The disinfection component 1000 is disposed inside the housing 100, which has a disinfection port 1001. The disinfection component 1000 and the disinfection port 1001 are correspondingly arranged, and the air outlet 201 and the disinfection port 1001 are arranged sequentially along the direction from the entrance door towards the interior. Thus, by placing the disinfection component 1000 on the side of the air curtain facing the interior, it can effectively extinguish bacteria and viruses agitated by the air curtain. Furthermore, the entrance area is generally where users change clothes and shoes and dispose of garbage, making it prone to bacterial or viral growth. The disinfectant emitted by the disinfection component 1000 will spread in the entrance area with the airflow carried by the air curtain, effectively extinguishing bacteria and viruses in the entrance area and preventing their spread, thus better protecting the user's health.

[0076] Optionally, such as Figure 14 As shown, the disinfection component 1000 includes a charged spray water tank 1002 and a charged nozzle 1003. The charged spray water tank 1002 is used to store water; the charged nozzle 1003 is connected to the charged spray water tank 1002 and is used to generate negatively charged water mist. In this way, the charged nozzle 1003 can atomize the water in the charged spray water tank 1002 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.

[0077] Optionally, multiple charged nozzles 1003 are provided, and each charged nozzle 1003 is correspondingly disposed in a disinfection port 1001. In this way, by setting multiple charged nozzles 1003 to spray disinfectant from different disinfection ports 1001, viruses and bacteria can be killed more comprehensively.

[0078] Optionally, multiple charged nozzles 1003 are connected to the same charged spray water tank 1002, or the charged spray water tank 1002 is provided with multiple one-charge nozzles corresponding to one charged spray water tank 1002. Alternatively, one charged spray water tank 1002 can correspond to two charged nozzles. In this way, multiple charged nozzles 1003 sharing one charged spray water tank 1002 can reduce the number of charged spray water tanks 1002 used, simplify the installation structure, and make it more convenient to add water to the charged spray water tank 1002.

[0079] Optionally, such as Figure 15 As shown, the charged nozzle 1003 includes an atomizing component 1004 and an annular electrode 1005. The atomizing component 1004 is used to atomize water; the annular electrode 1005 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 1004 passes through the middle region of the annular electrode 1005, 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.

[0080] Optionally, the atomizing component 1004 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 1005.

[0081] Optionally, the annular electrode 1005 is connected to a positive high-voltage transformer. This generates a positive high-voltage electric field in the annular electrode 1005, 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 fire extinguishing effect against bacteria and viruses.

[0082] Optionally, the charged nozzle 1003 also includes a grounding wire 1006, which is connected to the middle region of the annular electrode 1005. This allows positively charged ions repelled by the positive high-voltage electric field to be discharged through the grounding wire, thus protecting the sprayed water mist from the influence of positively charged ions and ensuring it carries a stable negative charge.

[0083] Optionally, multiple annular electrodes 1005 are provided, and the radii of the multiple annular electrodes 1005 are different. In this way, when connected to the same voltage source, the electric field strength generated by the different radii of the annular electrodes 1005 is different. The smaller the radius of the annular electrode 1005, the stronger the electric field generated. Therefore, when using a small atomization amount and a small radius annular electrode 1005, 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 make bacteria lose their activity. At the same time, its oxidizing property can also decompose the odor components (organic matter), thereby achieving the effect of sterilization and deodorization. Conversely, when using a large atomization volume and a large-radius annular electrode 1005, the weak electric field can only cause the surface charge of the water mist to accumulate but not decompose. At this time, it can adsorb particulate matter such as dust and PM2.5, thus cleaning the air. Therefore, multiple annular electrodes 1005 with different radii are set up, and different radii of annular electrodes 1005 can be selected to be turned on according to needs. This allows the output water mist to sterilize and disinfect while also adsorbing particulate matter such as dust and PM2.5, making the overall function of the disinfection component 1000 more powerful.

[0084] Optionally, multiple ring electrodes 1005 are connected to the same positive high-voltage transformer. This allows the multiple ring electrodes 1005 to be powered by the same positive high-voltage transformer, improving the stability of the power supply to the multiple ring electrodes 1005, ensuring consistent connection voltages for the multiple ring electrodes 1005, simplifying the structure, and reducing overall cost.

[0085] Optionally, multiple annular electrodes 1005 are connected to a positive high-voltage transformer via a switching switch. This allows the multiple annular electrodes 1005 to work alternately via the switching switch, generating different types of disinfectant water mist. This ensures the water mist achieves both adsorption and sterilization effects, better treating the environment and maintaining air quality in the entryway.

[0086] Optionally, two annular electrodes 1005 are provided, and the radius of one annular electrode 1005 is half the radius of the other annular electrode 1005. In this way, the smaller the radius of the annular electrode 1005, the greater the electric field strength it generates. By setting the radius of one annular electrode 1005 to half the radius of the other annular electrode 1005, one annular electrode 1005 can generate a strong electric field and the other an weak electric field. With the alternating operation of the two annular electrodes 1005, water mist particles with good bactericidal effect and water mist particles with good adsorption effect can be generated.

[0087] Optionally, the charged nozzle 1003 further includes a water flow channel 1007. The atomizing component 1004 and the annular electrode 1005 are both disposed within the water flow channel 1007, with the atomizing component 1004 positioned upstream of the annular electrode 1005. Thus, after water from the charged spray tank 1002 enters the water flow channel 1007, it is first atomized at the atomizing component 1004 to generate water mist. The water mist then passes through the annular electrode 1005, where it becomes charged under the electric field generated by the annular electrode 1005. 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 1004 upstream of the annular electrode 1005 allows the water to be atomized before entering the electric field, improving the uniformity of the water mist's charge and thus enhancing the water mist's sterilization and disinfection properties, or its adsorption capacity.

[0088] Optionally, the annular electrode 1005 with a smaller radius is positioned upstream of the annular electrode 1005 with a larger radius. In this way, since water will disperse after atomization, positioning the annular electrode 1005 with a smaller radius upstream facilitates the dispersion of the water mist passing through the annular electrode 1005, making the distribution of water droplets in the water mist more sparse and uniform, and facilitating the charging of water droplets.

[0089] Optionally, the disinfection component 1000 is also mounted on the movable plate 901 and can be moved out of the housing 100 along with the movable plate 901. This facilitates the addition of water to the charged spray water tank 1002 in the disinfection component 1000, improving ease of use.

[0090] Combination Figure 16 As shown, in some embodiments, the in-home air curtain unit also includes a display screen 1100. The display screen 1100 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 1100, 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 1100 can also connect to a smart peephole or surveillance camera via wireless communication (Bluetooth, etc.) to display outside surveillance images. Users do not need to go to the door; they can see visitors from a distance.

[0091] Optionally, the display screen 1100 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 updates of information displayed on the screen 1100, ensuring timely information delivery and providing a better user experience by making full use of the time users spend changing clothes and shoes in the entryway.

[0092] Optionally, the display screen 1100 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 903, and the remaining water in the charged spray tank 1002. The remaining amount of aromatherapy in the aromatherapy box 903 and the remaining water in the charged spray tank 1002 can be obtained through level sensors located inside the aromatherapy box 903 and the charged spray tank 1002, or through weight sensors located on the lower side of the aromatherapy box 903 and the lower side of the charged spray tank 1002. 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.

[0093] Optionally, the display screen 1100 is a single LCD screen embedded in the front of the housing 100 facing the interior. The display screen 1100 is tilted at a set angle towards the entrance door from top to bottom. This allows users to easily look up when standing at the door. The set angle is greater than or equal to 10 degrees and less than or equal to 30 degrees, preferably 20 degrees.
