Description

Technical Field

[0001] This utility model relates to the field of ventilation device technology, specifically an indoor ventilation device based on the Internet of Things. Background Technology

[0002] Indoor ventilation systems are environmental control systems that improve air quality by exchanging indoor and outdoor air through mechanical or natural means. Their core functions include introducing fresh air, expelling stale air, regulating temperature and humidity, and filtering pollutants. Common types include windows, vents, and exhaust fans. However, these systems often lack proper filtration systems, making it easy to draw unclean outside air into the room. Furthermore, they lack corresponding detection devices, making them cumbersome to use. Therefore, an Internet of Things (IoT)-based indoor ventilation system is designed to address these issues.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 This utility model provides a technical solution: an indoor ventilation device based on the Internet of Things, comprising: an external filter 1, an internal interface 2, and a controller 3. The external filter 1 includes a hollow outer shell 11, a filter tank 12 fixedly connected to the middle of the inner shell 11, a particulate filter 13 threadedly connected to the lower end of the inner shell 12, a moisture filter 14 fixedly connected to the upper end of the particulate filter 13, the upper end of the particulate filter 13 communicating with the lower end of the moisture filter 14, and the upper end of the moisture filter 14 communicating with the interior of the filter tank 12. The upper end of the filter canister 12 is connected to an end cap 15 by a thread. The lower end of the outer shell 11 is fixedly connected to an air inlet 16. The upper side of the air inlet 16 communicates with the interior of the filter canister 12. The left side of the filter canister 12 is fixedly connected to an air inlet pipe 17. The right side of the interior of the outer shell 11 is fixedly connected to an air outlet pipe 18. Both the air inlet pipe 17 and the air outlet pipe 18 are connected to a fan 19. The upper ends of both the air inlet pipe 17 and the air outlet pipe 18 are fixedly connected to an internal interface 2. The controller 3 is equipped with a wireless signal transmission module. The controller 3 is electrically connected to the two fans 19.

[0025] During use, the controller 3 is equipped with a carbon dioxide concentration detection module, a temperature and humidity detection module, and a dust detection module. These modules detect the carbon dioxide concentration in the air, the indoor humidity and temperature, and the dust concentration, and display the data on the screen. Users can also view the data via a smart device using a wireless signal transmission module. During installation, the external filter 1 is fixed to the outside of the wall in the same way as the air conditioner outdoor unit to reduce noise. Holes are drilled at the locations where air intake and exhaust are needed. The internal interface 2 is then inserted and filled with expanding foam. The installation is secured with bolts. The air intake pipe 17 and the air exhaust pipe 18 are connected to their corresponding internal interfaces 2. Corresponding mounting slots are drilled in the wall, and the controller 3 is installed inside the mounting slot. Users can then... View and set parameters via mobile phone, computer, or controller 3. The fan 19 in the air intake duct 17 is a mixing fan, which has a large pressure when started. Air will enter the particulate filter 13 through the air intake 16 for filtration. The filtered air will enter the moisture filter 14, which is filled with desiccant. After absorbing some of the moisture, it will be discharged through the outer side of the upper end into the filter tank 12 and drawn into the room by the fan 19 in the air intake duct 17. At the same time, the fan 19 in the air outlet duct 18 is started. The fan 19 in the air outlet duct 18 is an axial flow fan with low air pressure but large air volume, which draws indoor air to the outside to form a circulation and reduces the dust content in the air. When the filter system needs to be replaced or cleaned, simply open the cover on the outer shell 11, remove the end cap, hold the handle on the moisture filter 14 and rotate it to remove it.

[0026] like Figure 1-5 As shown, this utility model embodiment provides an implementation method in which the lower end of the filter tank 12 is sloped.

[0027] Analysis of the above structure shows that the lower end of the filter canister 12 is sloped, which can guide the particulate filter 13 and facilitate its insertion into the threaded position.

[0028] like Figure 1-4 As shown, this utility model embodiment provides an implementation method. Based on the above implementation method, the air inlet 16 and the air outlet 18 extend to the outside of the outer shell 11 with opposite opening directions.

[0029] Analysis of the above structure shows that by ensuring that the inhaled air is not the same as the exhaled air, more fresh air can be inhaled.

[0030] like Figure 1-4As shown in the figure, this utility model embodiment provides an implementation method. Based on the above implementation method, a filter screen 21 is fixedly connected inside the opening at the lower end of the air inlet 16 and the air outlet pipe 18, and a filter screen 21 is also snapped into the opening at the front end of the internal interface 2.

[0031] Analysis of the above structure shows that the filter screen 21 at the opening of the air inlet 16 and the air outlet 18 can prevent clogging, while the filter screen snapped into the front opening of the internal interface 2 can prevent some impurities from entering, and the snap-fit ​​can also facilitate replacement and cleaning.

[0032] like Figure 1-5 As shown, this utility model embodiment provides an implementation method. Based on the above implementation method, sealing rings are attached to the inner side of the opening at the upper end of the outer shell 11 and the lower surface of the inner side of the filter tank 12.

[0033] Analysis of the above structure shows that the sealing ring at the opening at the upper end of the outer shell 11 can reduce the flow of water into the interior of the outer shell 11, while the sealing ring on the lower surface of the inner side of the filter canister 12 can reduce the direct discharge of air through the gap at the connection between the particulate filter 13 and the lower end of the filter canister 12.

[0034] like Figure 1-4 As shown, this utility model embodiment provides an implementation method in which the diameter of the air intake pipe 17 is larger than the diameter of the air outlet pipe 18.

[0035] Analysis of the above structure shows that the diameter of the air intake pipe 17 is larger than the diameter of the air outlet pipe 18, and the model of the fan 19 installed in the air intake pipe 17 is also larger than that of the fan 19 in the air outlet pipe 18, which can reduce the airflow required by the filtration system.

[0036] like Figure 1-5 As shown, this utility model embodiment provides an implementation method. Based on the above implementation method, the outer shell 11 and the filter tank 12 are both made of stainless steel.

[0037] Analysis of the above structure shows that the outer shell 11 and the filter canister 12 are both made of stainless steel, which can reduce the impact of rust and corrosion and extend the service life.
