Description

    BACKGROUND Technical Field
  • The present application relates to air purification equipment technology, and in particular, to an indoor and outdoor ventilation device.
    • Description of Related Art
  • The deterioration of indoor air quality caused by an exhaustion of human physiological activities and an invasion of outdoor air pollutants has increasingly endangering human health. Improving indoor air quality has become a top priority for the environment. With the development of society, current air pollution has become a normal condition. With the advent of smog, existing equipment has shown its shortcomings: 1. The existing air treatment equipment that is really effective for smog is still in a state of high price, and needs to arrange air ducts and other facilities, and is not suitable for home installation. 2. The existing household room air filter has many practical drawbacks, such as the ventilation device cannot be opened in rainy days, once turned on, the rain may penetrate into the room through the air inlet pipe. 3. The existing technology does not consider the indoor air circulation, which cannot achieve a good air filtration effect.
    • SUMMARY
  • Based on the technical problems existing in the background art, the present application proposes an indoor and outdoor ventilation device.
  • The present application provides an indoor and outdoor ventilation device, which includes a fan, an air inlet casing, and an exhaust window. The air inlet casing is adapted to be installed on an outdoor side. An air inlet and an air outlet are arranged on the air inlet casing. A filter net and an air filter are sequentially installed in the air inlet casing from the air inlet to the air outlet. The fan is adapted to be installed on an indoor side, and the fan is communicated with the air outlet. The exhaust window is mounted on a wall body to vent indoor air to an outside.
  • In a preferred technical solution, a one-way valve is arranged on the exhaust window, and the indoor air flows to the outside through the one-way valve.
  • In a preferred technical solution, the exhaust window and the fan are respectively mounted on opposite wall bodies.
  • In a preferred technical solution, the air inlet is located at a bottom of the air inlet casing.
  • In a preferred technical solution, the air filter is detachably mounted on the air inlet casing.
  • In a preferred technical solution, an insertion opening is arranged on the air inlet casing, and the air filter is inserted into the air inlet casing through the insertion opening.
  • In a preferred technical solution, a latch is mounted on the air inlet casing near the insertion opening. The latch includes a socket and a plug. The socket is fixed on the air inlet casing, and the plug is sealed at the insertion opening in a state where the plug protrudes from the socket.
  • In the indoor and outdoor ventilation device of the present application, the fan and the air inlet casing pump the outdoor air to the indoor, and the exhaust window discharges the indoor air to the outdoor, so that the indoor air and the outdoor air can continue to circulate, thus the indoor air continues to be updated, so as to remove dust, toxic gases, etc. from the room; and the air filter is detachably mounted on the air inlet casing, and it is convenient to replace the air filter.
    • BRIEF DESCRIPTION OF THE DRAWINGS
  • FIG. 1 is a structural schematic view of an indoor and outdoor ventilation device according to the present application.
  • FIG. 2 is a structural schematic view of an air inlet casing of the indoor and outdoor ventilation device according to the present application.
    •  DESCRIPTION OF THE EMBODIMENTS
  • As shown in FIGS. 1-2, FIG. 1 is a structural schematic view of an indoor and outdoor ventilation device according to the present application; FIG. 2 is a structural schematic view of an air inlet casing of the indoor and outdoor ventilation device according to the present application.
  • Referring to FIG. 1 and FIG. 2, the indoor and outdoor ventilation device proposed in the present application includes a fan 1 installed on an indoor side, an air inlet casing 2 and an exhaust window 3 installed on an outdoor side. A through hole is formed in a wall body. The fan 1 and the inlet casing 2 are oppositely disposed on both sides of the through hole. An air inlet and an air outlet are arranged on the air inlet casing 2. A filter screen 5 is installed in the air inlet. The air filter 4 is installed inside the air inlet casing 2. The air outlet is connected with the through hole. The exhaust window 3 and the fan 1 are installed on the same wall body. The exhaust window 3 is used to discharge the air from the inside to the outside. The exhaust window 3 and the fan 1 are arranged apart from each other by a distance. The fan 1 pumps the outdoor air into the air inlet casing 2 through the filter screen under a working state, and the outdoor air is pumped into the inside after being filtered by the air filter 4, and then is discharged to the outside through the exhaust window 3, so that the indoor air is updated to bring dust, toxic gases, etc. from the inside to the outside.
  • In the present embodiment, a one-way valve 31 is arranged on the exhaust window 3. An inlet of the one-way valve 31 is close to the indoor side, and an outlet of the one-way valve 31 is close to the outdoor side. The indoor air can only flow to the outside through the one-way valve. The advantage of this design is that the outdoor air does not enter the inside through the exhaust window 3, and avoids a conflict between the outdoor air entering the room through the exhaust window 3 and the outdoor drawing in by the fan 1, which cannot achieve the purpose of indoor and outdoor air circulation.
  • In another embodiment, the exhaust window 3 and the fan 1 are respectively mounted on oppositely disposed wall bodies for better circulation and ventilation.
  • The air inlet casing 2 in the embodiment has a triangular prism shape, and the air inlet and the air outlet are respectively arranged on a right-angle side of the triangular prism. When installing, the outlet is installed at the through hole of the wall body, and the air inlet is facing downward. It is designed that rainwater will not enter the air inlet casing 2 through the air inlet in a rainy day, so the ventilation device can be normally opened in the rainy day, and there is no need to worry about the rain entering the room.
  • An insertion opening 21 is arranged on the air inlet casing 2, and the air filter 4 is inserted into the air inlet casing 2 through the insertion opening 21. A latch 6 is mounted on the air inlet casing 2 near the insertion opening 21. The latch 6 includes a socket and a plug. The socket is fixed on the air inlet casing 2, and the plug is sealed at the insertion opening 21 to restrict removal of the air filter 4 through the insertion opening 21.
  • The above description is only the preferred embodiment of the present application, but the scope of protection of the present application is not limited thereto, and any equivalents or modifications of the technical solutions of the present application and the application concept thereof should be included in the scope of the present application within the scope of the technical scope of the present application.
