Description

Technical Field

[0001] This invention relates to a fresh air device, and more particularly to a fresh air device specifically designed for pets, belonging to the technical field of fresh air purification systems and pet-specific solutions. Background Technology

[0002] With the development of the pet market, people keep various pets at home, such as common cats and dogs. Pet toilets, such as cat litter boxes, are places for pets to excrete waste, which can generate moisture and various odors. They need to be ventilated and changed in a timely manner to dehumidify and remove odors.

[0003] For example, application number 202520413429.7 discloses a housing, cover plate, fan, odor removal component, disinfection component and filter component. An air outlet is opened on one side wall of the housing, and the fan is set on the side of the housing away from the air outlet. The air outlet and the fan are connected through an air duct.

[0004] The existing pet air purifiers mentioned above do not have a dedicated fresh air system. The existing purification equipment can only perform internal circulation filtration, which is not convenient for circulating and filtering internal and external air. They can only filter particulate matter and hair, and cannot solve the problems of pet odor, organic gases and bacteria.

[0005] To overcome the lack of dedicated fresh air systems in existing pet air purifiers, which can only perform internal circulation filtration and are not convenient for circulating and filtering both internal and external air, and can only filter particulate matter and pet hair, failing to address pet odors, organic gases, and bacteria, a dedicated fresh air system for pets is needed for further improvement and optimization. Summary of the Invention

[0006] The main purpose of this invention is to overcome the limitations of existing pet air purifiers, which lack dedicated fresh air systems. Existing purification devices can only perform internal circulation filtration, making it inconvenient to circulate and filter both internal and external air. They can only filter particulate matter and pet hair, and cannot solve the problems of pet odor, organic gases, and bacteria. This invention provides a dedicated fresh air device for pets.

[0007] The objective of this invention can be achieved by adopting the following technical solution: A pet-specific fresh air system includes a main fresh air unit for air circulation; The upper inner section of the main fresh air unit is equipped with a total heat exchange core, and HEPA filters are installed on both sides of the total heat exchange core. The upper section of the main fresh air unit is symmetrically equipped with indoor return air inlets and outdoor air inlets. The lower section of the main fresh air unit is symmetrically equipped with indoor air supply outlets and outdoor air exhaust outlets. Through a special ventilation structure, heat and humidity are transferred between the fresh air and exhaust air without direct contact. In winter, the heat from the exhaust air is recovered to heat the fresh air, reducing heating energy consumption. In summer, the cold air from the exhaust is recycled to pre-cool the fresh air, reducing the load on the air conditioning and preventing the pets from feeling uncomfortable due to the direct blowing of fresh air. HEPA filters use high-efficiency filter materials to filter pet hair, dander, mold spores, bacteria, and fine particulate matter from the air, solving the problems of odor and allergen buildup in pet-keeping environments and ensuring indoor air cleanliness.

[0008] Preferably, an indoor air supply fan is installed on the lower section of the inner fresh air main unit of the indoor air supply vent, and an outdoor exhaust fan is installed on the lower section of the inner fresh air main unit of the outdoor air exhaust vent.

[0009] Preferably, a hinge is installed on one side of the top of the main fresh air unit, and a cover is installed on the outer hinge end of the hinge. With the hinge and cover on the top of the main fresh air unit, opening the cover allows direct contact with the internal heat exchange core and HEPA filter, facilitating regular cleaning or filter replacement and ensuring the long-term efficient operation of the equipment.

[0010] Preferably, a control panel is installed on the outside of the main fresh air unit. The control panel is electrically connected to the heat exchange core, HEPA filter, indoor air supply fan, and outdoor exhaust fan. Using the control panel as the system control center, the fan speed and fresh air volume can be adjusted, while the equipment operating status can be monitored, enabling functions such as automatic start / stop and filter replacement reminders, adapting to the pet-keeping needs of different scenarios.

[0011] Air entering the main fresh air unit through the indoor return air inlet passes through a HEPA filter and a total heat exchange core before being exhausted by the outdoor exhaust fan and outdoor exhaust outlet.

[0012] Preferably, the total heat exchange core and HEPA filter, which enter the main fresh air unit through the outdoor air inlet, are introduced by the indoor air supply fan and indoor air outlet. The HEPA filter is located at the fresh air inlet and intercepts pollutants such as outdoor dust, pollen, PM2.5, and aerosols. It is the core of the purification process and achieves high-efficiency interception of PM2.5μm particles, which are the most easily penetrating particles, through four physical actions: inertial impaction, interception effect, Brownian diffusion, and electrostatic adsorption. At the same time, it prevents large particles from entering the exchange core, thus preventing the core from becoming clogged and moldy.

[0013] Preferably, air is circulated internally and externally through the main fresh air unit, indoor return air inlet, outdoor air inlet, indoor supply air outlet, and outdoor exhaust air outlet. The total heat exchange core located in the middle of the unit is the core of energy saving. It is made of a moisture-permeable but airtight polymer membrane or paper membrane, which simultaneously recovers sensible heat and latent heat. Sensible heat recovery temperature: In winter, it recovers heat from indoor exhaust air and preheats outdoor fresh air; In summer, it recovers the cold air from indoor exhaust and pre-cools the outdoor fresh air, thus reducing the air conditioning / heating load. Latent heat recovery humidity: By utilizing the water vapor transfer characteristics of the membrane material, the humidity of fresh air is regulated, thus avoiding dry indoor air in winter and the introduction of high humidity air in summer.

[0014] Preferably, the main fresh air unit filters particulate matter of 0.1μm, 0.3μm, 1μm and 2.5μm.

[0015] Beneficial technical effects of the present invention: This invention provides a pet-specific fresh air device, a two-way flow total heat exchange fresh air system, which simultaneously purifies the air and recovers energy; When the equipment is running, the indoor supply fan and the outdoor exhaust fan start synchronously to form two independent airflows, and complete the heat and moisture exchange at the total heat exchange core. Outdoor fresh air enters the main fresh air unit through the outdoor air inlet. It first passes through a HEPA filter on one side to filter out particulate matter such as dust, pollen, and PM2.5, preventing pollutants from entering the pet's activity space. The purified air enters the total heat exchange core, where it exchanges temperature and humidity with the polluted air exhausted from the room, recovering energy. The fresh air that has undergone heat and humidity recovery is driven by the indoor fan and delivered into the room through the indoor air outlet, providing pets with clean, fresh air with suitable temperature and humidity. The polluted indoor air containing pet hair, odors, and carbon dioxide enters the main fresh air unit through the indoor return air vent. It also passes through the HEPA filter on the other side to intercept pollutants such as hair and dander, preventing contamination of the total heat exchange core. The purified polluted air enters the total heat exchange core, where it transfers its temperature and humidity to the fresh air. Then, driven by the outdoor exhaust fan, the air is discharged outdoors through the outdoor exhaust vent, thus achieving continuous indoor air renewal. Utilizing the principle of indoor and outdoor air circulation purification, fresh air is continuously supplied to the pet room or pet carrier through ducts. Outdoor air passes through a heat exchange core to reduce heat loss and improve temperature comfort. After passing through a high-efficiency filter to filter out particulate matter smaller than PM2.5 from the outdoor air, it is then supplied to the indoor or pet room through the indoor air outlet. The indoor return air outlet exhausts the air to the outside through an independent negative pressure exhaust duct, maintaining a slight negative pressure indoors to keep the air clean. This structure effectively avoids air conditioning energy loss and keeps the pet room or carrier in a relatively clean environment, providing a healthy environment for both people and pets.

[0018] To enable those skilled in the art to understand the technical solution of the present invention more clearly, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, this embodiment provides a pet-specific fresh air device, including a main fresh air unit 1 for air circulation; The upper inner section of the main fresh air unit 1 is equipped with a total heat exchange core 1.1, and HEPA filters 1.2 are installed on both sides of the total heat exchange core 1.1. The upper section of the main fresh air unit 1 is symmetrically equipped with an indoor return air inlet 2 and an outdoor air inlet 3; The lower section of the main fresh air unit 1 is symmetrically equipped with an indoor air supply outlet 2.1 and an outdoor air exhaust outlet 3.1.

[0020] An indoor air supply fan 1.3 is installed in the lower section of the inner fresh air main unit 1 of the indoor air supply outlet 2.1, and an outdoor exhaust fan 1.4 is installed in the lower section of the inner fresh air main unit 1 of the outdoor exhaust outlet 3.1.

[0021] A hinge 1.6 is installed on one side of the top of the main fresh air unit 1, and a cover 1.5 is installed on the outer hinge end of the hinge 1.6.

[0022] A control panel 4 is installed on the outside of the main fresh air unit 1. The control panel 4 is electrically connected to the total heat exchange core 1.1, the HEPA filter 1.2, the indoor air supply fan 1.3 and the outdoor exhaust fan 1.4.

[0023] Air entering the main fresh air unit 1 through the indoor return air inlet 2 passes through the HEPA filter 1.2 and the total heat exchange core 1.1 and is then discharged by the outdoor exhaust fan 1.4 and the outdoor exhaust outlet 3.1.

[0024] The total heat exchange core 1.1 and HEPA filter 1.2, which enter the main fresh air unit 1 through the outdoor air inlet 3, are introduced by the indoor air supply fan 1.3 and indoor air supply outlet 2.1.

[0025] The air is circulated internally and externally through the main fresh air unit 1, indoor return air inlet 2, outdoor air inlet 3, indoor supply air outlet 2.1 and outdoor exhaust air outlet 3.1.

[0026] The main fresh air unit 1 filters particles of 0.1μm, 0.3μm, 1μm and 2.5μm.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the whole unit integrates fresh air introduction, exhaust energy recovery, air purification and airflow circulation. The core is divided into three parts: airflow system, total heat exchange system and purification system, which simultaneously realizes three major functions: ventilation, energy saving and purification. The overall airflow direction is as follows: This equipment has a bidirectional flow structure, with two independent air ducts inside, and the air intake and exhaust are completely separated and do not mix. This application involves outdoor air → indoor air, with polluted outdoor air → primary filter → HEPA high-efficiency filter → total heat exchange core → fan pressurization → delivery into the room; Exhaust path: This application involves an indoor-outdoor airflow process: indoor polluted air (odors, carbon dioxide, and moisture) → primary filter → total heat exchange core 1.1 → fan → exhaust to the outside. The two airflows cross and flow in opposite directions within the exchange core without contacting each other, only transferring temperature and humidity energy.

[0028] The airflow direction table is as follows:

[0029] By having two airflows flow in a cross-counterflow state within the total heat exchange core, energy is transferred without gas mixing, thus ensuring the cleanliness of the fresh air.

[0030] The fans are configured independently: indoor supply fan 1.3 is responsible for pressurized air supply, and outdoor exhaust fan 1.4 is responsible for forced exhaust. The air volume can be matched as needed. The core principle of total heat exchange: The total heat exchange core 1.1 can transfer sensible heat temperature + latent heat vapor / humidity; Temperature exchange: Sensible heat recovery In winter: The warm air exhausted from indoors transfers heat to the cold fresh air outdoors, increasing the intake air temperature and reducing heating energy consumption; Summer: The cool air exhausted from indoors cools down the hot outdoor fresh air, reducing the load on the air conditioning system. Humidity exchange: latent heat recovery; Relying on the core's properties of being breathable yet airtight, it enables moisture transfer, expelling excess indoor moisture during the rainy season / summer and reducing the humidity of fresh air. In the dry winter, it retains indoor moisture and prevents the fresh air from causing the indoor air to become dry.

[0031] The heat exchange performance data are as follows:

[0032] Air purification system principle: This application adopts a graded filtration structure, intercepting pollutants in multiple stages according to the airflow sequence, adapting to indoor air safety requirements. The pre-filter intercepts hair, lint, and large dust particles, protecting the downstream filter material. The HEPA filter 1.2 relies on impact, interception, Brownian diffusion, and electrostatic adsorption to filter PM2.5, ultrafine particles, pollen, bacterial aerosols, etc., with a filtration efficiency of ≥99.97%. The purification performance data is as follows: HEPA filter;

[0033] The overall workflow of the entire machine is as follows: When the equipment's fan starts, it creates bidirectional convection. The outdoor fresh air first passes through multiple filters for purification, removing dust, microorganisms, and harmful gases. The purified fresh air enters the total heat exchange core and exchanges temperature and humidity energy with the indoor exhaust air; Clean fresh air, after temperature and humidity regulation, is continuously supplied into the room to replenish oxygen and dilute CO2 and pollutants. The stale indoor air is extracted, undergoes simple filtration, flows through the exchange core to release energy, and is finally discharged outdoors.

[0034] This application adopts a bidirectional flow total heat exchange + HEPA purification fresh air unit, which is divided into a fresh air side and an exhaust air side. The two airflows cross heat exchange and are physically separated, realizing ventilation, energy saving and purification in one.

[0035] Located at the fresh air intake end, it intercepts outdoor pollutants such as dust, pollen, PM2.5, and aerosols, and is the core of the purification system.

[0036] Filtration mechanism: It achieves efficient interception of PM2.5μm particles, which are the most easily penetrating particles, through four physical processes: inertial impaction, interception effect, Brownian diffusion, and electrostatic adsorption.

[0037] Protective function: It also prevents large particles from entering the exchange core, thus preventing the core from becoming clogged or moldy.

[0038] Total heat exchange core: Located in the middle of the equipment, it is the core of energy saving, made of a moisture-permeable but airtight polymer membrane or paper membrane, which recovers both sensible and latent heat. Sensible heat recovery temperature: In winter, it recovers the heat from indoor exhaust air and preheats the outdoor fresh air; in summer, it recovers the cold air from indoor exhaust air and precools the outdoor fresh air, reducing the air conditioning / heating load.

[0039] Latent heat recovery humidity: By utilizing the water vapor transfer characteristics of the membrane material, the humidity of fresh air is regulated to avoid dry indoor air in winter and the introduction of high humidity air in summer.

[0040] The fresh air equipment in this application consists of a main fresh air unit 1, a total heat exchange core 1.1, a HEPA filter 1.2, an indoor supply fan 1.3, an outdoor exhaust fan 1.4, an indoor return air inlet 2, an outdoor air inlet 3, an indoor supply air outlet 2.1, an outdoor exhaust air outlet 3.1, and a control panel 4. The above structure forms a bidirectional flow total heat exchange fresh air system, which simultaneously takes into account air purification and energy recovery. When the equipment is running, the indoor air supply fan 1.3 and the outdoor exhaust fan 1.4 start synchronously, forming two independent airflows, and completing heat and moisture exchange at the total heat exchange core 1.1; Outdoor fresh air enters the main fresh air unit 1 through the outdoor air inlet 3. It first passes through the HEPA filter 1.2 on one side to filter out particulate matter such as dust, pollen, and PM2.5, preventing pollutants from entering the pet's activity space. The purified air enters the total heat exchange core 1.1, where it exchanges temperature and humidity with the polluted air exhausted from the room, recovering energy. The fresh air that has undergone heat and humidity recovery is driven by the indoor fan 1.3 and delivered into the room through the indoor air outlet 2.1, providing pets with clean, fresh air with suitable temperature and humidity. The polluted indoor air containing pet hair, odors, and carbon dioxide enters the main fresh air unit 1 through the indoor return air vent 2, and also passes through the HEPA filter 1.2 on the other side to intercept pollutants such as hair and dander, thus preventing contamination of the total heat exchange core. The purified polluted air enters the total heat exchange core 1.1, where it transfers its temperature and humidity to the fresh air. Then, driven by the outdoor exhaust fan 1.4, the air is exhausted outdoors through the outdoor exhaust vent 3.1, thus achieving continuous renewal of indoor air.

Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed in the present invention, based on the technical solution and concept of the present invention, shall fall within the scope of protection of the present invention.
