[0038] Example

[0039] The multifunctional eco-friendly living space device provided in this embodiment, such as Figures 1-3 As shown, it includes a fresh air system, an exhaust air system, a heat recovery system, and a filtration system, wherein:

[0040] The fresh air system includes a fresh air motor 4, a fresh air inlet 9, and a fresh air outlet 14;

[0041] The exhaust system includes an exhaust fan 16, an exhaust inlet 11, and an exhaust outlet 6;

[0042] The heat recovery system includes a heat exchange core 8, which is connected to a fresh air inlet 9 and an exhaust air inlet 11, respectively, for exchanging the temperature of the fresh air entering from the outside and the exhaust air leaving the room.

[0043] The filtration system includes a high-efficiency filter 13 installed in the fresh air path and an exhaust pre-filter 10 installed in the exhaust air path. The high-efficiency filter 13 is located between the fresh air motor 4 and the heat exchange core 8, and the exhaust pre-filter 10 is located between the exhaust inlet 11 and the heat exchange core 8.

[0044] The multifunctional eco-friendly living space device using the above technical solution achieves bidirectional airflow circulation by having the fresh air motor 4, fresh air inlet 9, and fresh air outlet 14 of the fresh air system work in concert with the exhaust fan 16, exhaust inlet 11, and exhaust outlet 6 of the exhaust system. The heat exchange core 8 can exchange indoor and outdoor air temperatures and regulate the fresh air temperature to reduce indoor temperature differences. The high-efficiency filter 13 and the exhaust pre-filter 10 filter the fresh air and exhaust air respectively, achieving air purification, improving the overall indoor air quality and maintaining a stable temperature.

[0045] Specifically, in this embodiment, a negative ion generator module 2 is also included. The negative ion generator module 2 is disposed within the fresh air outlet 14 and is used to release negative ions into the air supplied through the fresh air outlet 14. By placing the negative ion generator module 2 within the fresh air outlet 14, it can release negative ions into the room along with the fresh air, increasing the concentration of negative ions in the indoor air, simulating the air conditions in a natural environment, enhancing the eco-friendly effect, and improving air quality.

[0046] Specifically, in this embodiment, a sensing component is also included, comprising a sensor module 15. The sensor module 15 includes a carbon dioxide sensor, a VOC sensor, a temperature sensor, and a PM2.5 sensor. The sensor module 15 is located inside the device near the exhaust inlet 11. The sensor module 15, containing carbon dioxide, VOC, temperature, and PM2.5 sensors and located near the exhaust inlet 11, can directly and in real-time monitor the concentration of gaseous pollutants, temperature, and particulate matter content in indoor air, providing accurate environmental parameters for system operation and adjustment, and ensuring effective perception of the indoor environmental conditions.

[0047] Specifically, this embodiment also includes a sterilization system, which includes an ultraviolet lamp. The ultraviolet lamp is positioned on the side of the high-efficiency filter 13 near the heat exchange core 8 to sterilize the air before it enters the high-efficiency filter 13. Positioning the ultraviolet lamp on the side of the high-efficiency filter 13 near the heat exchange core 8 allows for sterilization of the air before it enters the high-efficiency filter 13, preventing the filter from growing mold and bacteria due to damp conditions, preventing the filter from becoming a secondary source of pollution, and ensuring the cleanliness of the filtration system.

[0048] Specifically, in this embodiment, the high-efficiency filter 13 is an H13 HEPA filter, and the fresh air motor 4 is a centrifugal fan with a vortex housing. The air inlet of the high-efficiency filter 13 is connected to the air outlet of the heat exchange core 8, and the air outlet is connected to the air inlet of the fresh air motor 4. The high-efficiency filter 13, using an H13 HEPA filter and located before the fresh air motor 4, can efficiently filter fine particulate matter such as PM2.5 and pollen in the fresh air. Combined with the air-drawing effect of the centrifugal fan fresh air motor 4 with its vortex housing, it ensures that the fresh air entering the room has undergone deep purification before passing through the motor, significantly improving the cleanliness of the fresh air.

[0049] Specifically, in this embodiment, the exhaust pre-filter 10 is a G4 HEPA filter. The air inlet of the exhaust pre-filter 10 is connected to the exhaust inlet 11, and the air outlet is connected to the exhaust air inlet of the heat exchange core 8. The exhaust pre-filter 10 uses a G4 HEPA filter, which can perform preliminary filtration of indoor air entering the exhaust system, intercepting larger particulate pollutants and preventing them from entering the heat exchange core 8 and causing pollution or blockage, thus ensuring the heat exchange efficiency of the heat exchange core 8 and extending its service life.

[0050] Specifically, in this embodiment, an auxiliary heating device, namely a PTC heater 3, is also included. The PTC heater 3 is installed in the fresh air path between the fresh air motor 4 and the fresh air outlet 14, and is used to heat the air delivered by the fresh air motor 4. The PTC heater 3, located in the fresh air path between the fresh air motor 4 and the fresh air outlet 14, can automatically heat the air delivered by the fresh air motor 4 when the indoor temperature is lower than a set value, compensating for insufficient temperature regulation in the heat recovery system, ensuring a suitable temperature for the fresh air supplied to the room, and maintaining a constant indoor temperature.

[0051] Specifically, in this embodiment, the fresh air outlet 14 is a 360-degree adjustable air outlet, and its outlet angle can be adjusted by rotating in both horizontal and vertical directions. The 360-degree adjustable fresh air outlet 14 allows users to flexibly adjust the outlet angle according to their needs, ensuring that fresh air is evenly distributed to different areas of the room, meeting the ventilation needs of different spaces, and improving the flexibility and comfort of using the device.

[0052] Specifically, in this embodiment, the sensor module 15 is electrically connected to the fresh air motor 4 and the exhaust fan 16. The carbon dioxide sensor and the VOC sensor are used to adjust the operating power ratio of the fresh air motor 4 and the exhaust fan 16 according to the detected indoor gaseous pollutant concentration. By electrically connecting the sensor module 15 to the fresh air motor 4 and the exhaust fan 16, the carbon dioxide sensor and the VOC sensor can automatically adjust the operating power ratio of the two according to the detected gaseous pollutant concentration, realize the dynamic matching of fresh air volume and exhaust air volume, accurately control the indoor gaseous pollutant content, and ensure that the indoor air is continuously fresh.

[0053] Specifically, in this embodiment, the temperature sensor is electrically connected to the PTC heater 3. When the indoor temperature is detected to be lower than a preset value, the PTC heater 3 is automatically activated to heat the fresh air. By electrically connecting the temperature sensor to the PTC heater 3, the PTC heater 3 is automatically triggered to turn on when the indoor temperature is detected to be lower than the preset value. This heats the fresh air to compensate for heat loss, ensuring that the indoor temperature remains stable within a comfortable range and preventing a sudden drop in room temperature due to the introduction of fresh air.

[0054] Specifically, in this embodiment, the PM2.5 sensor is positioned near the fresh air outlet 14 to monitor the PM2.5 concentration of the air delivered through the fresh air outlet 14 in real time. Positioning the PM2.5 sensor near the fresh air outlet 14 allows for direct monitoring of the PM2.5 concentration of the treated fresh air, providing real-time feedback on the fresh air purification effect. This facilitates users' understanding of the cleanliness of the delivered air and provides a basis for judging the operating status of the filtration system.

[0055] Specifically, in this embodiment, the fresh air inlet 9 and the exhaust outlet 6 are both located on the back of the device, while the fresh air outlet 14 and the exhaust inlet 11 are both located on the front of the device. Furthermore, the positions of the fresh air inlet 9 and the exhaust outlet 6, and the fresh air outlet 14 and the exhaust inlet 11, are staggered. This staggered arrangement of the fresh air inlet 9 and the exhaust outlet 6, and the fresh air outlet 14 and the exhaust inlet 11 on the front and back of the device reduces the probability of freshly exhausted polluted air being directly drawn into the fresh air inlet 9, thus reducing cross-contamination between fresh and exhaust air, ensuring the freshness of the introduced fresh air, and improving overall ventilation efficiency.

[0056] Specifically, in this embodiment, the negative ion generator probe 1 is located inside the fresh air outlet 14 and connected to the negative ion generator module 2, with its probe end facing the airflow channel of the fresh air outlet 14. The concentration of negative oxygen ions released by the negative ion generator module 2 is monitored in real time, and the signal is fed back to the electronic control area 5 to ensure that the release of negative oxygen ions remains stable within the range required for the simulated ecological environment, avoiding excessively high or low concentrations that could affect air quality.

[0057] Specifically, in this embodiment, the electrical control area 5 is located inside the device, near the fresh air motor 4 and the exhaust fan 16, and is connected to the sensor module 15, the fresh air motor 4, the exhaust fan 16, the PTC heater 3, the negative ion generator module 2, and the ultraviolet lamp via circuitry. As the control core of the device, it receives carbon dioxide, VOC, temperature, and PM2.5 concentration signals transmitted from the sensor module 15, as well as negative oxygen ion concentration signals from the negative ion generator probe 1. Through a preset program, it automatically adjusts the operating power of the fresh air motor 4 and the exhaust fan 16, the start and stop of the PTC heater 3, the sterilization duration of the ultraviolet lamp, and the release intensity of the negative ion generator module 2, thereby achieving coordinated operation of all systems.

[0058] Specifically, in this embodiment, the primary fresh air filter 7 is located on the fresh air path between the fresh air inlet 9 and the heat exchange core 8. Its inlet end is connected to the fresh air inlet 9, and its outlet end is connected to the fresh air inlet end of the heat exchange core 8. It performs preliminary filtration on the outdoor fresh air entering the device, intercepting large particulate impurities (such as dust, insects, hair, etc.) in the fresh air, preventing large particulate pollutants from entering the heat exchange core 8 and causing blockage or contamination, thus protecting the heat exchange efficiency of the heat exchange core 8. Simultaneously, it reduces the filtration load on the subsequent high-efficiency filter 13 and extends the service life of the high-efficiency filter 13.

[0059] In summary, the working principle of the multifunctional eco-friendly living space device provided in this embodiment is as follows:

[0060] The principle behind this device's ability to regulate a simulated ecological living space through the collaborative operation of multiple systems is as follows:

[0061] 1. Air circulation and purification: The fresh air system (fresh air motor 4, fresh air inlet 9, fresh air outlet 14) and the exhaust system (exhaust fan 16, exhaust inlet 11, exhaust outlet 6) work together to introduce fresh outdoor air while expelling stale indoor air, thus forming air circulation.

[0062] 2. Temperature regulation: The heat exchange core 8 exchanges the temperature of indoor exhaust air and outdoor fresh air to initially balance the fresh air temperature; when the indoor temperature is too low, the auxiliary heating device (PTC heater 3) will automatically turn on to heat the fresh air and maintain a constant indoor temperature.

[0063] 3. Filtration and sterilization: In the fresh air path, outdoor air first passes through the high-efficiency filter 13 (H13 HEPA filter) to filter particulate matter, and the ultraviolet lamp in front of the filter element sterilizes the air to prevent the filter from growing mold and bacteria; in the exhaust air path, indoor air is initially filtered by the exhaust pre-filter 10 (G4 HEPA filter) to avoid contaminating the heat exchange core 8.

[0064] 4. Ecological and intelligent regulation: The negative ion generator module 2 at the fresh air outlet 14 releases negative oxygen ions to simulate the natural environment; the sensor module 15 (including carbon dioxide, VOC, temperature, and PM2.5 sensors) monitors the indoor environment in real time and adjusts the air volume ratio between the fresh air motor 4 and the exhaust fan 16, as well as the start and stop of the PTC heater 3, to ensure environmental stability.

[0065] How to use

[0066] 1. Installation: Install the device at a height of about 60cm from the ground. Make through-wall holes on the wall corresponding to the fresh air inlet 9 and exhaust outlet 6 on the back of the device. Install through-wall vent caps in the holes to ensure unobstructed airflow.

[0067] 2. Operation: After the equipment is started, indoor polluted air enters from the bottom exhaust inlet 11, passes through the exhaust pre-filter 10 (G4 HEPA filter) to filter larger particles, and the heat exchange core 8 (exchanges temperature with outdoor fresh air), and is finally discharged to the outside by the exhaust fan 16 through the exhaust outlet 6.

[0068] 3. Outdoor fresh air enters from the fresh air inlet 9, passes through the heat exchange core 8 (absorbing the heat or cold of the indoor exhaust air) and the high-efficiency filter 13 (H13 HEPA filter to filter fine particulate matter) in sequence, and is delivered to the fresh air outlet 14 by the fresh air motor 4 (centrifugal fan with vortex).

[0069] 4. At the same time, the negative ion generator module 2 inside the fresh air outlet 14 releases negative oxygen ions, which are sent into the room along with the purified fresh air; the 360-degree adjustable fresh air outlet 14 allows users to manually adjust the air outlet angle to adapt to different space needs.

[0070] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
