Technical Field

[0001] This patent relates to the field of air purification equipment, specifically a multifunctional and efficient indoor drone air purifier, belonging to the field of environmental protection technology. Background Technology

[0002] In recent years, people's awareness of environmental protection has shifted from outdoor to indoor environments. Surveys show that indoor air pollution levels are ten to a hundred times higher than outdoor levels. Therefore, indoor air purification has become particularly important.

[0003] Currently, most indoor air purifiers suffer from a single processing method, making it difficult to achieve centralized and efficient capture of multiple pollutants, and to provide comprehensive and in-depth purification through multi-functional treatment. This patent provides a multi-functional and highly efficient indoor air purifier. Summary of the Invention

[0004] The purpose of this patent is to provide a multi-functional and high-efficiency indoor air purifier that can activate different purification schemes in two different situations to solve the problems of difficulty in centralized processing and comprehensive purification mentioned in the background art.

[0005] To achieve the above objectives, this patent provides an air purifier with two purification modes: a main unit and sub-units. When air pollution is weak, the sub-units activate purification. Each sub-unit connects to four air purifiers that operate simultaneously. Each air purifier has a ventilation cavity extending from both the top and bottom. The purifier also includes a control device, a power unit, and an air purification device. The control device controls the power unit to generate flight propulsion, allowing the sub-units to sequentially pass through several predetermined target points. The air purification device purifies the airflow. When air pollution is strong, the main unit activates purification, powered by a drum-type cross-flow fan, creating a circulating purification process. First, a screen filters out mosquitoes and large particles. Then, an electrostatic precipitator effectively removes bacteria and fine dust. Finally, micro-silver-loaded activated carbon effectively removes formaldehyde.

[0006] Preferably, the air purifier generally has 2 to 4 sub-units, and the number and placement of the sub-units can be arranged according to the actual situation and the distribution of pollution sources in the space.

[0007] Preferably, each purification unit of the air purifier mother unit and daughter units is equipped with an anti-collision detection device on its outer wall, that is, multiple infrared sensors.

[0008] Preferably, the air purifier sub-unit is equipped with an automatic charging device at its stop position, which can automatically charge the sub-unit after it returns to its position and automatically disconnect the power when it is fully charged.

[0009] Preferably, the air purifier of the sub-unit is provided with a sliding door at the outer end for filter replacement.

[0010] Preferably, the power unit of the air purifier in the sub-unit is located above the air purifier.

[0011] Preferably, the detection device includes an air quality sensor, a temperature sensor, and a humidity sensor, which can simultaneously detect indoor air quality and temperature and humidity.

[0012] Preferably, the connecting board of the sub-machine is equipped with a battery to power the negative ions.

[0013] Ideally, the set target point can be connected to a mobile app via a wireless connection point to receive information such as pollution source location and air quality, and can also be remotely controlled.

[0014] Preferably, the connecting plate of the sub-unit can be a negative ion release plate to reduce the load.

[0015] Ideally, different purification routes can be planned for the two sub-units to improve efficiency.

[0016] Ideally, the target point can be changed in real time according to the level of indoor pollution or sudden situations, and different purification routes can be flexibly activated.

[0017] Preferably, the signal tower connecting the slave unit and the master unit of this multi-functional high-efficiency indoor air purifier can be wirelessly controlled.

[0018] Ideally, this multi-functional, high-efficiency indoor air purifier is suitable for larger spaces, such as office areas.

[0019] Preferably, the multi-functional high-efficiency indoor air purifier will generate a small amount of noise during operation, but this will not affect normal work and life; therefore, it should be avoided from operating during rest periods. Preferably, the sub-units of the multi-functional high-efficiency indoor air purifier should be limited to a certain height range.

[0020] The beneficial effects of this patent are: the multi-functional and high-efficiency indoor air purifier provided by this patent can not only achieve large-area purification, but also start different purification schemes in two situations according to the degree of pollution. For situations where there are multiple pollution sources indoors, it improves the flexibility of air treatment and achieves comprehensive pollution control in a highly efficient and rapid manner.

[0044] The structure of a multifunctional and efficient indoor air purifier device according to this patent will be further described below with reference to the accompanying drawings.

[0045] The structure of the multifunctional, high-efficiency indoor air purifier device described in this patent is shown in [reference]. Figures 2 to 7 The device includes a housing (44), an alarm device (1), a storage battery (7), and also includes a mother system (6) and a daughter system (2).

[0046] like Figure 1 As shown, the main workflow of this multi-functional high-efficiency indoor air purifier is as follows: The main unit's detection device monitors air quality in real time and outputs an air status signal to the central processing unit (CPU). Upon receiving the signal, if the CPU indicates strong air pollution, it transmits a control signal to the main unit, activating its air purification device. If the signal indicates weak air pollution, it transmits the control signal to the slave unit, activating its air purification device. Simultaneously, the slave unit itself can also monitor air quality and transmit signals to both itself and the system's CPU. The system's information receiver is responsible for receiving the air quality index.

[0047] Specifically, in one embodiment, if the host system (6) receives a signal from the central processing unit, purification is activated. Figure 3 First, mosquitoes and larger particles are filtered through the shielding net (8). Then, the electrostatic tungsten wire in the electrostatic dust collector (10) releases high voltage static electricity, effectively adsorbing micro-dust PM2.5 and isolating germs. After passing through the formaldehyde removal module (5), the airflow passes through the open shell (16) and through the micro-nano silver activated carbon (17) to treat formaldehyde for a long time. Finally, the impeller (15) of the drum-type crossflow fan (4) rotates to discharge the purified air.

[0048] In another embodiment, if the subsystem (2) receives a signal from the central processing unit, purification is initiated. The subsystem performs inspection and purification along the established target points. As one example, such as Figure 4In this embodiment, the outer shell (22) of the air purifier (25) of the submachine is roughly cylindrical, for example, made of lightweight material. Furthermore, the connecting plate (24) of the submachine houses a detection device (26), a controller (30), and a displacement sensor (32). The ventilation cavity of the air purifier (25) contains a power unit (20) and an air purification device (21). The power unit (20) generates lift by driving high-speed airflow, for example, using a rotor (36) structure or other suitable structural form. The air purification device (21) can be positioned above or below the power unit (20). In this embodiment, the air purification device (21) is positioned below the power unit (20). It should be understood that the air purification device (21) has a certain airflow capacity to ensure that the power unit (20) can provide sufficient lift. To ensure unrestricted flight of the submachine, a battery is used to power the various electrical components; for example, the battery is a lithium battery, thereby reducing the overall weight of the machine.

[0049] Specifically, such as Figure 6 The ventilation cavity is equipped with a mounting bracket (39) located on the central axis of the ventilation cavity and multiple support arms connected between the mounting bracket (39) and the inner wall of the ventilation cavity, arranged circumferentially around the mounting bracket (39). The power unit (20) includes a drive motor (38) and a rotor (36) fixed on the output shaft of the motor (38). In order to better stabilize the drive motor (38), the mounting bracket (39) is formed to accommodate the drive motor (38) in a shape that is adapted to the shape of the drive motor (38). The air purification device (21) uses a HEPA filter (40) as an example, which can be replaced.

[0050] Specifically, in one implementation, the target point is equipped with a wireless connection point, which can be a wireless router, Bluetooth communication module, etc. The central processing unit of the host is equipped with a corresponding wireless communication module. The central processing unit receives signals of different strengths emitted by the wireless connection point at different locations and generates an indoor air purification map to identify the one-to-one correspondence between different locations in the room and different wireless connection points with different strengths of signals, thereby realizing the positioning function of the slave unit and real-time monitoring of indoor air quality indicators.

[0051] Considering the potential for inaccuracies in wireless network positioning of the sub-unit and the inevitable movement of indoor items by users, to prevent collisions with obstacles during flight, the air purifier casing (22) of the sub-unit in this embodiment also includes an anti-collision detection device (23) for detecting obstacles. When the anti-collision detection device detects an obstacle, the control device controls the sub-unit to avoid the obstacle, thereby adjusting the flight path according to the actual situation, protecting both the sub-unit from collision damage and indoor items from damage. In a specific embodiment, the anti-collision detection device uses infrared sensors as an example. Multiple infrared sensors arranged along the circumference are provided on the outer surface of the air purifier casing to achieve 360° all-around obstacle detection.

[0052] In addition, the sub-unit of this embodiment also includes a detection device (26) for detecting air quality, a controller (30), and a displacement sensor (32). Figure 4 The detection device (26) includes a humidity sensor (27), a temperature sensor (28), and an air quality sensor (29). For example, the air detection device (26) can detect a variety of air pollutants, such as PM2.5, formaldehyde, and indoor temperature and humidity. The controller (30) controls the hovering time of the sub-unit at the target point according to the detection results output by the air detection device (26). For areas with severe air pollution, the purification time is appropriately extended to ensure the purification effect. For areas with less air pollution, the purification time is appropriately shortened. In some areas where the air quality meets the standards, the sub-unit does not stop at all to improve the utilization rate. The displacement sensor (32) can control the lifting speed and provide real-time feedback of air quality information at different heights during the lifting process of the sub-unit.

[0053] In addition, such as Figure 5 In one embodiment, a negative ion releasing plate (33) is attached below the connecting plate (24) of the sub-unit. While purifying, it actively releases negative ions into the air, thus achieving the purpose of purifying the air. An ultraviolet sterilization lamp (34) is embedded in the central groove (35) of the negative ion releasing plate (33), which can simultaneously achieve the purpose of sterilization.

[0054] like Figure 7 The upper part of the air purifier casing (44) is a liquid crystal touch screen (42), which displays parameters such as air quality at different locations in real time and can switch between multiple modes, such as automatic and manual. Above the liquid crystal touch screen (42) is an air status indicator light (41) that displays the indoor air status. The lower part is a sliding door, which is secured by a latch (43) for easy maintenance of the internal system of the main unit.

[0055] The above description is merely a preferred embodiment of this patent. The above embodiments are only illustrative of the principles and effects of this patent, and are not intended to limit this patent in any form or substance. It should be noted that those skilled in the art can make several improvements and additions without departing from the method of this patent, and these improvements and additions should also be considered within the scope of protection of this patent.
