Description

Technical Field

[0001] This utility model relates to the field of air purification technology, and in particular to a modular multi-effect air purification device. Background Technology

[0002] As people become more safety-conscious, more and more people are paying attention to their own and their families' health. This has led to the emergence of various air purifiers on the market, including those targeting PM2.5, formaldehyde, those with negative ions, and those with ultraviolet sterilization capabilities, among others.

[0003] Current air purifiers or air sterilizers typically only meet specific air purification needs. For example, they may only adsorb dust, or only treat harmful gases like formaldehyde, or offer a limited combination of purification capabilities. If multiple purification needs are desired, multiple air purifiers must be purchased. Even some air purifiers on the market that claim to be multi-functional often have limited effectiveness in removing various pollutants and cannot adequately meet diverse purification requirements. Therefore, there is a need for an air purifier that can be flexibly combined according to user needs and can efficiently treat indoor pollutants. Utility Model Content

[0049] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0050] Terminology Explanation:

[0051] Environmental sensors are sensors that detect the detection indicators of the surrounding environment. There are usually sensors for particulate matter, such as PM sensors, sensors for gaseous pollution, such as TVOC sensors, formaldehyde sensors, etc., and temperature and humidity sensors. Among them, temperature and humidity sensors mostly use temperature and humidity integrated probes as temperature measuring elements to collect temperature and humidity signals. After being processed by circuits such as voltage stabilization filtering, operational amplification, nonlinear correction, V / I conversion, constant current and reverse protection, they are converted into current signals or voltage signals that are linearly related to temperature and humidity and output, or can also be directly output through interfaces such as 485 or 232 by the main control chip.

[0052] NTC thermistor: A thermosensitive element whose resistance value decreases as the temperature increases. In this embodiment, it is used for the temperature monitoring of the electromagnet, with the model MF52, an accuracy of ±1%, and is installed between the iron core and the coil.

[0053] Reference Figures 1 to 12As shown, this embodiment provides a modular multi-effect air purification device, including a smart base 1 and stackable modular air purification modules 2 (each with its own sensors corresponding to purification requirements); the smart base 1 includes a smart control module 16, a voice interaction module 15, a base status display module 14, a base power supply and communication module 13 (including a base power supply connector 17 and a base communication connector 18), a basic environmental detection module 12, and a basic purification module 11; the voice interaction module 15, the base status display module 14, the base power supply and communication module 13, and the basic environmental detection module 12... The environmental detection module 12, basic purification module 11, and intelligent control module 16 are connected; the modular air purification module 2 includes a control module 25, a module power supply and communication module 24, an environmental sensor 22, a module status display module 23, and a purification module 21, which includes a fan and a filter; the module power supply and communication module 24, environmental sensor 22, module status display module 23, fan, and control module 25 are connected; the base power supply and communication module 13 is located on the top of the intelligent base 1, and the module power supply and communication module 24 is located on the bottom of the modular air purification module 2. The top section includes a first module power supply connector 26, a first module communication connector 27, a second module power supply connector 29, and a second module communication connector 30. The smart base 1 has a base electromagnet 19 on its top, and the modular air purification module 2 has a metal block 28 on its bottom and a module electromagnet 31 on its top. The smart base 1 and the modular air purification module 2 are hot-swappably connected via a base power supply and communication module 13 on the top of the smart base 1 and a module power supply and communication module 24 on the bottom of the modular air purification module 2. This allows the smart base 1 to supply power to the modular air purification module 2 and enables communication between them. The module power supply and communication module 24 on the top of the modular air purification module 2 is used to connect with the module power supply and communication module on the bottom of the next-level modular air purification module 3, enabling the stacking of multiple modular air purification modules. The smart control module 16 of the smart base 1 communicates with the control module 25 of the modular air purification module 2 to send control commands to the modular air purification module 2 and receive working status information uploaded by the modular air purification module 2.

[0054] In this embodiment, the base electromagnet 19 and the module electromagnet 31 are made of neodymium iron boron permanent magnet material, with a surface magnetic induction intensity ≥0.5T and a single electromagnet adsorption area ≥50cm². 2 Under rated current (2A), the single-group adsorption force is ≥50N.

[0055] In this embodiment, the attraction force between the electromagnet at the top of the smart base and the metal block at the bottom of the modular module must meet the following requirements: the attraction force of a single electromagnet under rated current is not less than twice the weight of a single module, and the maximum number of stacked layers does not exceed 5 layers.

[0056] The modular air purification module 2 weighs ≤2kg individually. The theoretical maximum number of stacked layers is calculated as follows: Total adsorption force = Adsorption force of a single unit × Number of electromagnets (2 sets each for the smart base and the bottom of the module), i.e., 50N × 2 × 2 = 200N, which can support a weight of approximately 20kg (approximately 10 modules). In practical applications, the maximum number of stacked layers is limited to 5 (total weight ≤10kg), with a 50% safety margin.

[0057] In this embodiment, the electromagnet at the top of the smart base and the metal block at the bottom of the modular module adopt a boss-groove positioning structure. The boss height is 0.5±0.1mm and the groove depth is 0.6±0.1mm. It works in conjunction with the positioning post-positioning hole structure to achieve mechanical positioning of the cascaded modules.

[0058] The base electromagnet 19 at the top of the smart base 1 and the metal block 28 at the bottom of the modular air purification module 2 adopt a "boss-groove" positioning structure. The boss height is 0.5mm, the groove depth is 0.6mm, and the fit tolerance is ±0.1mm, ensuring automatic alignment during adsorption and eliminating the influence of mechanical tolerances. The boss-groove positioning structure, together with the positioning post-positioning hole structure, jointly achieves the mechanical positioning of the cascaded modules.

[0059] In this embodiment, a positioning post and positioning hole mating structure is provided between the top of the smart base and the bottom of the modular module. The diameter of the positioning post is 3±0.1mm and the diameter of the positioning hole is 3.1±0.05mm, which is used to assist the electromagnet and the metal block in precise alignment.

[0060] Four positioning posts (such as...) are set around the power supply and communication module 13 at the top of the smart base. Figure 1 The base electromagnet 19 has a columnar structure with a diameter of 3±0.1mm and a height of 2mm. The module power supply and communication module 24 at the bottom of the modular module has a positioning hole with a diameter of 3.1±0.05mm and a tolerance of ±0.05mm to ensure accurate alignment of the electromagnet and the metal block during insertion and removal.

[0061] In this embodiment, a heat sink is provided on the outside of the electromagnet, and the heat sink is in contact with the module shell. The overlapping gap between the modules is not less than 5mm, which is used for air convection heat dissipation.

[0062] The top module electromagnet 31 and the bottom bottom electromagnet 19 of the modular air purification module 2 are equipped with aluminum heat sinks (1mm thick) on the outside. The heat sinks are in contact with the module shell and dissipate heat through air convection. A 5mm ventilation gap is reserved between the modules to ensure heat dissipation.

[0063] In this embodiment, the intelligent control module 16 monitors the temperature of the electromagnet and adjusts the power supply current according to the temperature. When the temperature exceeds the threshold, it performs power reduction or power-off protection.

[0064] The NTC thermistor (model MF52, accuracy ±1%) is installed inside the insulation layer between the electromagnet core and the coil. It communicates with the intelligent control module 16 to monitor the core temperature in real time. When the temperature exceeds 60℃, it automatically reduces the current by 10%. When the temperature exceeds 80℃, it triggers an alarm and cuts off the power supply to prevent demagnetization.

[0065] In this embodiment, positioning posts and positioning holes are provided around the adsorption surfaces of the base electromagnet 19 and the metal block 28 to assist in mechanical alignment and ensure accurate connection of the power supply and communication interfaces. After testing, following two hours of operation with the five-layer module stacked, the electromagnet surface temperature stabilized at 55±3℃, not exceeding the 60℃ current reduction threshold, thus meeting the heat dissipation requirements.

[0066] In this embodiment, the base power supply and communication module 13 and the module power supply and communication module 24 adopt spring pin connectors (Pogo Pin) with a pin travel of 1mm, allowing a lateral offset of ±0.5mm, ensuring that electrical connection can still be achieved even if there are mechanical tolerances.

[0067] This modular multi-effect air purifier, through its modular design, allows users to combine air purification modules with different effects according to their needs. It utilizes various purification technologies, such as HEPA filtration, activated carbon adsorption, and ion purification, to comprehensively remove different types of pollutants and improve purification efficiency. Modules can be replaced or added / removed based on changes in the usage environment and needs, thus flexibly adjusting the purification function. The modular design eliminates the need to purchase different types of air purifiers while using multi-effect purification, reducing space requirements and operating costs. Through a high-efficiency motor and intelligent control, it automatically purifies and adjusts power based on air quality, improving energy efficiency and truly achieving energy saving, low carbon emissions, and environmental protection.

[0068] In this embodiment, the intelligent control module 16 includes buttons and a core control module, used for:

[0069] Controls the start / stop of the basic purification module 11 and adjusts the fan speed.

[0070] Based on the values ​​reported by the basic environmental detection module 12 and the built-in control model, the system controls the basic purification module 11 to start / stop and adjust the fan speed.

[0074] It receives control commands from the base power supply and communication module 13 and controls the basic purification module 11 and the modular air purification module 2 on the smart base 1.

[0075] The basic purification module 11 and the modular air purification module 2 on the smart base 1 can be controlled independently and uniformly.

[0076] In this embodiment, the voice interaction module 15 uses an offline or online voice module to convert voice into control commands, and controls the basic purification module 11 and the modular air purification module 2 on the smart base 1 through the intelligent control module 16.

[0077] In this embodiment, the base status display module 14 is used to display the working status of the smart base, including the working status and detection values ​​of the basic environmental detection module 12, the working status (whether it is working or not) of the voice interaction module 15, the working status (whether it is connected to the network, communicating, or powered on or not) of the base power supply and communication module 13, the working status (start / stop, fan speed level) of the basic purification module 11, and the status of whether the modular air purification module 2 is connected; it also displays the connection status and working status of the connected modular air purification module 2, including the working status (whether it is working or not) and detection values ​​of the environmental sensor 22, and the working status (start / stop, fan speed level) of the modular air purification module 2.

[0078] In this embodiment, the base power supply and communication module 13 includes a base power supply connector 17 and a base communication connector 18. The base communication connector 18 connects to a third-party communication module to support mobile phones and cloud platforms in viewing the overall operating status of the air purifier and the working status of each module. It also supports sending control commands via mobile phones and cloud platforms to the intelligent control module, which controls the basic purification module and modular air purification modules on the intelligent base. The third-party communication modules include Bluetooth, Wi-Fi, and 2G, 3G, 4G, and 5G modules. The base power supply and communication module 13 provides power and control output for each functional module of the air purifier. The modular air purification modules are connected to the intelligent base through the module power supply and communication module, which provides power to the modular air purification modules to ensure their normal operation. The module also reports the current working status of the modular air purification modules to the intelligent control module and can receive control commands from the intelligent control module.

[0079] In this embodiment, the basic environmental detection module 12 is equipped with environmental detection sensors, including temperature and humidity sensors, particulate matter sensors, etc., to detect the environmental quality of the space where the device is located, and transmit the detected values ​​to the intelligent control module 16 on the intelligent base 1.

[0080] In this embodiment, the basic purification module 11 includes a fan and a high-efficiency purification filter. Its air intake and exhaust methods include front-to-back air intake and left-to-right air exhaust, left-to-right air intake and front-to-back air exhaust, three-sided air intake and one-sided air exhaust, or bottom air intake and four-way air exhaust. It can also be any combination except for the top (the top would connect to a modular purification module and could not be made into an air duct for exhaust). (Refer to...) Figure 12 As shown in the example, the bottom layer is the basic purification module of the smart base, with air intake at the front and back and air outlet at both sides. The second layer is the VOC and formaldehyde purification module, with air intake at both sides and air outlet at the front. The third layer is the all-effect purification module, with air intake at three sides and air outlet at the top.

[0081] In this embodiment, the control module 25 is used to control the switch of the modular air purification module 2, receive control commands from the mobile phone and cloud platform, and control the modular air purification module 2 to start / stop and adjust the fan speed. When the modular air purification module is connected to the smart base and powered on, it can be controlled to start / stop and adjust the fan speed via the buttons on the smart base; it can also be controlled to start / stop and adjust the fan speed based on the control model built into the smart base; it can also be controlled to start / stop and adjust the fan speed via the voice interaction module on the smart base; or it can be controlled to start / stop and adjust the fan speed via control commands from the mobile phone and cloud platform.

[0082] In this embodiment, the module power supply and communication module 24, after connecting to the smart base 1, enables the modular air purification module 2 to receive power, reports the operating status of the modular air purification module 2 and the environmental data collected by the environmental sensor 22 to the smart base 1; simultaneously, it transmits the control commands issued by the smart base 1 to the control module 25. After connecting to the smart base, the modular air purification module receives power and reports its operating status (on / off, fan speed) and the environmental data collected by the environmental sensor on the module to the smart base; simultaneously, it transmits the control commands issued by the smart base to the module's control module.

[0083] In this embodiment, the environmental sensor 22 includes a formaldehyde detection sensor, a VOC detection sensor, an allergen detection sensor, etc., and reports the detected data to the smart base via the power supply and communication module during operation. The module status display module 23 is used to display the current working status and alarm information of the modular air purification module 2. The fan is used to draw air from the environment into the air purification device by rotating, and outputs purified air after filtration by the filter element. The filter element is used to filter the polluted air drawn in by the fan to produce clean air, and the filter element includes a filter device composed of HEPA, activated carbon, and composite materials for removing other gaseous pollutants.

[0084] In a specific example, the smart base connects to the modular air purification module via a set of power connectors on its top, providing the necessary power for the module's operation. Similarly, another set of communication connectors on the top of the smart base allows the modular air purification module to be monitored after it is powered on. An electromagnet is placed around each of the power and communication connectors on the smart base, while a magnetically attracted metal block is placed around each of the modular air purification module's power and communication connectors. Both the power and communication connectors can use industry-standard pogo pin connectors; pogo pins are chosen because they offer strong versatility, capable of both signal and power transmission. Likewise, the modular air purification module also has a set of power and communication connectors on its top for connecting to the module and facilitating power and communication.

[0085] Taking a 5-layer module as an example, each module weighs 1.8kg, the total weight is 9kg, the attraction force of a single electromagnet is 50N×2 sets=100N, the safety factor is 100N / 9kg≈11.2 (far greater than the 2 times safety redundancy requirement), after 72 hours of continuous operation test, no module detachment or electromagnetic demagnetization phenomenon occurred.

[0086] The smart base is equipped with a basic purification module that uses a 50W motor and features a front and rear air intake and left and right air outlet design. It uses two filters to absorb pet hair, pollen, and other allergens, assisting in the treatment of pet hair and odors. The basic environmental monitoring module includes temperature and humidity sensors, particulate matter sensors, and allergen sensors to monitor real-time environmental data such as temperature, humidity, PM2.5, PM10, and pollen allergens in the surrounding space.

[0087] Two modular air purification modules are integrated into the smart base: a module specifically for formaldehyde and VOCs, and an all-around purification module. The formaldehyde and VOC purification module uses a 50W motor and features a left-right air intake and front-facing air outlet. Its two filters primarily remove VOCs and formaldehyde, and also remove odorous gases such as acetic acid, hydrogen sulfide, methanethiol, trimethylamine, and acetic acid. This module is equipped with formaldehyde and VOC sensors, allowing for real-time monitoring of formaldehyde, VOCs, and odorous gases in the surrounding space after power-on. The all-around purification module uses a 40W motor, features a three-sided air intake and top-facing air outlet, and is equipped with plasma and UV disinfection modules for further disinfection and removal of viruses and bacteria in the air.

[0088] The smart base can use a full-touch color screen to display and control the basic purification module and connect to the modular air purification module.

[0089] The device controls the basic purification module and connected modular air purification module of the smart base through offline voice interaction, as well as the complete function guidance and operation interaction provided by the device, including network configuration, status alarms (filter-related, network-related, fault-related, etc.).

[0090] The intelligent control module includes buttons and a core control module. It controls the basic purification module of the smart base to start / stop and adjust the fan speed. Based on values ​​reported by the basic environmental detection module and the built-in control model, it controls the basic purification module of the smart base to start / stop and adjust the fan speed. It monitors the connection status of the modular air purification module, its operational status after connection, and the detection values ​​reported by the environmental sensors on the module. It controls the modular air purification module to start / stop and adjust the fan speed using buttons or based on the built-in control model. It receives control commands from the voice interaction module to control the basic purification module and modular air purification module on the smart base.

Furthermore, the buttons and core control module of the intelligent control module support independent and unified control of the basic purification module and modular air purification module on the smart base.
