[0029] The following will describe in detail the specific embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for explaining and illustrating the present utility model, and are not used to limit the present utility model.

[0030] In the prior art, the fresh air system includes an installation box, a ventilation duct, a fan, a heating box and a total heat exchanger. The installation box is fixed to the ventilation duct so that the ventilation duct supports the installation box. The ventilation duct occupies most of the space of the installation box to make the air circulation more efficient. The fan is arranged in the ventilation duct to increase the fluidity of indoor and outdoor air. The heating box is fixed in the installation box to serve as a transfer station for fresh air and exhaust air. The total heat exchanger is fixed in the middle of the installation box to exchange the temperature and humidity of indoor and outdoor air. An air flow partition plate is arranged in the middle of the total heat exchanger to separate the fresh air and exhaust air in the heating box. However, in the prior art, due to the lack of firm fixation of the body, during the operation of the intelligent fresh air system, each component vibrates and collides slightly, thus generating abnormal noises. Therefore, the present utility model is proposed.

[0031] As Figures 1-3 shown, the intelligent fresh air system of the present utility model includes a fixing component 11, a ventilation component 12 and an installation box 15. The fixing component 11 includes a box body 111, a filter plate 112 and a fixing rod 113. The box body 111 is embedded in the wall and bolted to the wall. Part of the box body 111 is exposed outside the wall to support the fixing rod 113. The filter plate 112 is connected to the ventilation duct by plugging for easy installation and disassembly. The fixing rod 113 is arranged at one end of the box body 111 outside the wall. The ventilation component 12 includes a fresh air duct 121 and an exhaust air duct 122. The fresh air duct 121 and the exhaust air duct 122 are arranged in the box body 111 and have a certain strength to support the installation box 15.

[0032] In the above embodiments, the housing 111 is generally square, and a space is reserved in the middle of the housing 111 to provide installation space for the intelligent ventilation system circuit for installers. Sound insulation cotton blocks are installed in the installation box 15 to reduce the noise generated when the total heat exchanger works, and shock pads are installed under the fan to reduce the noise generated when the fan rotates. Two fans are provided in both the fresh air duct 121 and the stale air duct 122. When the fan in the fresh air duct 121 rotates, outdoor air flows into the room, and when the fan in the stale air duct 122 rotates, indoor air flows to the outside of the room.

[0033] In the above embodiments, semi-circular grooves are formed in both the fresh air duct 121 and the stale air duct 122. The filter plate 112 is detachably connected to the groove to filter impurities in the air, and the filter plate 112 can be replaced and cleaned after being removed. Two filter plates 112 are provided, and the two filter plates 112 are respectively arranged in the fresh air duct 121 and the stale air duct 122 inside the housing 111. One of the filter plates 112 is arranged at the fan air outlet of the fresh air duct 121 to filter the air entering the room from the outside, and the other filter plate 112 is arranged at the fan air outlet of the stale air duct 122 to filter the air flowing from the room to the outside, thereby cleaning the impurities in the indoor and outdoor air flow processes. A layer of filter mesh is fixed on both filter plates 112 to enhance the air filtering effect. The filter plate 112 is circular to be adapted to be installed in the fresh air duct 121 and the stale air duct 122, and there are several holes on the filter plate 112 to allow air to flow through.

[0034] The fixing component 11 of the present utility model further includes a slide rail 114. Connection holes for inserting the fresh air duct 121 and the stale air duct 122 are formed in the housing 111. The slide rail 114 is arranged on the inner wall around the connection holes, and the length of the slide rail 114 is adapted to the length of the housing 111. After the fresh air duct 121 and the stale air duct 122 are inserted into the connection holes, they are in contact with the slide rail 114 to slide the fresh air duct 121 and the stale air duct 122 under the action of the slide rail 114, so that the filter plates 112 on the fresh air duct 121 and the stale air duct 122 are exposed, facilitating the disassembly, cleaning and installation of the filter plates 112.

[0035] In the above embodiments, such as Figure 4As shown in the figure, a chute is provided on the slide rail 114, and a number of small steel balls are arranged in the chute. The outer walls of the fresh air duct 121 and the old air duct 122 are in contact with the small steel balls, so that when the fresh air duct 121 and the old air duct 122 are pushed and pulled, the fresh air duct 121 and the old air duct 122 slide in contact with the small steel balls. After the fresh air duct 121 and the old air duct 122 are pulled out of the box body 111, the filter plate 112 can be replaced. There are eight slide rails 114, and there are two slide rails 114 at the upper and lower positions of the fresh air duct 121 and the old air duct 122. Each slide rail 114 is in a semi-surround shape so that part of the bead body of the small steel ball is exposed outside for the fresh air duct 121 and the old air duct 122 to slide. Stop pieces are fixed at both ends of the slide rail 114 to limit the small steel balls, so as to prevent all the small steel balls from falling during the sliding of the fresh air duct 121 and the old air duct 122.

[0036] The fixing component 11 of the present utility model further includes a rack 115 and a tongue lock 116 to Figure 2 Illustrated in the direction, the fresh air duct 121 and the old air duct 122 are respectively arranged on the left and right sides of the installation box 15. There are two racks 115 respectively fixed on the right side of the fresh air duct 121 and the left side of the old air duct 122, and the length of the rack 115 is adapted to the box body 111. The tongue lock 116 is arranged on the wall and is rotatably connected to the wall. Rotating the tongue lock 116 can make the tongue lock 116 insert into the tooth gaps of the rack 115 to limit the sliding of the fresh air duct 121 and the old air duct 122, thereby avoiding the sliding of the fresh air duct 121 and the old air duct 122 from affecting the operation of replacing the filter plate 112 when the operator replaces the filter plate 112.

[0037] In the above embodiment, as Figure 1 shown, it is assumed that the installation box 15 is attached to the wall. At this time, the tongue lock 116 is restricted within the rack to limit the sliding of the fresh air duct 121 and the old air duct 122. As Figure 5As shown, the bottom of the rack 115 is closed to limit the tongue lock 116 within the rack 115. When a person replaces the filter plate 112, the person rotates the tongue lock 116 on the left wall counterclockwise around the X-axis so that the tongue lock 116 disengages from the tooth gaps of the left rack 115. The person rotates the tongue lock 116 on the right wall clockwise around the X-axis so that the tongue lock 116 disengages from the tooth gaps of the right rack 115. The person pulls the installation box 15 in the X-axis direction from the state of being attached to the wall, so that the installation box 15 drives the fresh air duct 121 and the stale air duct 122 to move synchronously in the X-axis direction, thereby exposing the filter plate 112 located on the fresh air duct 121 and the stale air duct 122. Further, the person rotates the tongue lock 116 on the left wall clockwise around the X-axis so that the tongue lock 116 inserts into the tooth gaps of the left rack 115, thereby restricting the sliding of the stale air duct 122. The person rotates the tongue lock 116 on the right wall counterclockwise around the X-axis so that the tongue lock 116 inserts into the tooth gaps of the right rack 115, thereby restricting the sliding of the fresh air duct 121. At this time, the person performs operations such as disassembling, cleaning, and installing the filter plate 112;

[0038] Similarly, after the installation of the filter plate 112 is completed, the person rotates the tongue lock 116 on the left wall counterclockwise around the X-axis so that the tongue lock 116 disengages from the tooth gaps of the left rack 115. The person rotates the tongue lock 116 on the right wall clockwise around the X-axis so that the tongue lock 116 disengages from the tooth gaps of the right rack 115. The person pushes the installation box 15 towards the wall, so that the installation box 15 drives the fresh air duct 121 and the stale air duct 122 to move synchronously towards the wall, thereby making the installation box 15 fit against the wall. Further, the person rotates the tongue lock 116 on the left wall clockwise around the X-axis so that the tongue lock 116 inserts into the tooth gaps of the left rack 115, thereby restricting the sliding of the stale air duct 122. The person rotates the tongue lock 116 on the right wall counterclockwise around the X-axis so that the tongue lock 116 inserts into the tooth gaps of the right rack 115, thereby restricting the sliding of the fresh air duct 121, and preventing the sliding of the fresh air duct 121 and the stale air duct 122 from affecting the ventilation efficiency.

[0039] The fixing component 11 of the present utility model further includes a telescopic rod 117. The telescopic rod 117 is arranged at the bottom of the box body 111 to support the installation box 15, as Figure 6As shown, the telescopic rod 117 has a structure of two circular rods. The outer circular rod is fixed inside the box body 111. One end of the inner circular rod is inserted and connected to the outer circular rod. When replacing the filter plate 112, a person pulls the installation box 15, causing the installation box 15 to drive the inner circular rod to be pulled out from the outer circular rod and expose the filter plate 112, so that the person can disassemble and replace the filter plate 112. At the same time, the installation box 15 obtains a supporting effect under the connection of the telescopic rod 117, preventing the fresh air duct 121 and the old air duct 122 from bending or breaking due to being unable to bear the weight of the installation box 15. An anti - detachment boss is provided at the position where the inner circular rod is inserted into the outer circular rod to prevent the inner circular rod from detaching from the outer circular rod when replacing the filter plate 112.

[0040] The ventilation component 12 of the present utility model further includes two hole covers 123. Limit rings are provided on both the fresh air duct 121 and the old air duct 122. As Figure 7 shown, one of the hole covers 123 is sleeved on the fresh air duct 121 and is snap - connected to the limit ring, and the other hole cover 123 is sleeved on the old air duct 122 and is snap - connected to the limit ring, so that the two hole covers 123 can rotate on the fresh air duct 121 and the old air duct 122 respectively without falling off. Ventilation holes are provided around the circumference and end face of the hole cover 123. When the power of the intelligent ventilation system reaches the maximum, the air flow at the hole cover 123 for air intake or air outlet is in a divergent form, thereby reducing people's perception of the incoming and outgoing air and improving comfort.

[0041] The intelligent fresh air system of the present utility model further includes a wind - guiding component 13. One set of wind - guiding components 13 is provided on each of the fresh air duct 121 and the old air duct 122. The wind - guiding component 13 includes a rotating cap 131, a connecting rod 132, a wind - blocking plate 133, and a rotating rod 134. As Figure 8 shown, taking the wind - guiding component 13 on the old air duct 122 as an example for illustration, the connecting rod 132 is located inside the hole cover 123 and is hinged to the hole cover 123 at both ends. Among them, the connecting rod 132 includes a connecting rod C and a connecting rod D to support the wind - blocking plate 133. One end of the connecting rod C is fixedly connected to the rotating cap 131, the other end of the connecting rod C is rotatably connected to the outside of the hole cover 123, both ends of the connecting rod D are rotatably connected to the outside of the hole cover 123, the rotating cap 131 is arranged on the outside of the hole cover 123 and is fixedly connected to the connecting rod 132, the wind - blocking plate 133 is located inside the hole cover 123 and is fixedly connected to the connecting rod 132. Among them, the wind - blocking plate 133 includes a wind - blocking plate E and a wind - blocking plate F to adjust the wind direction. Both ends of the rotating rod 134 are respectively rotatably connected to the connecting wind - blocking plate E and the wind - blocking plate F, and a connecting rod 132 hinged to the hole cover 123 is provided on the wind - blocking plate F to drive the wind - blocking plate E and the wind - blocking plate F to move synchronously under the movement of the rotating rod 134.

[0042] In the above embodiments, the specific process of adjusting the wind direction is as follows: the rotating cap 131 rotates counterclockwise around the Z-axis to synchronously rotate the connecting rod C and the wind deflector E. The wind deflector E rotates counterclockwise around the connecting rod C, thereby causing the rotating rod 134 to descend, so that the rotating rod 134 drives the wind deflector F to rotate counterclockwise around the connecting rod D. On the contrary, when the rotating cap 131 rotates clockwise around the Z-axis to synchronously rotate the connecting rod C and the wind deflector E, the wind deflector E rotates clockwise around the connecting rod C, thereby causing the rotating rod 134 to rise, so that the rotating rod 134 drives the wind deflector F to rotate clockwise around the connecting rod D. Finally, the adjustment of the wind direction is realized under the action of the wind deflector 133. Since the hole cover 123 is rotatable, the hole cover 123 can be rotated, and then the direction of the wind deflector 133 is adjusted, so that any wind direction position can be adjusted.

[0043] The intelligent fresh air system of the present invention further includes an intelligent component 14, such as Figures 9-10 As shown, the intelligent component 14 includes a sensor 141, a controller 142, a variable speed driver 143, a solar panel 144 and a storage battery 145. The sensor 141 is arranged on the installation box 15 and the fixed rod 113 to detect various indicators in the indoor and outdoor air. The controller 142 is arranged inside the box body 111 to control the operation of the intelligent fresh air system. The variable speed driver 143 is arranged inside the box body 111 to adjust the rotation speed of the fan according to the air quality detected by the sensor 141. The solar panel 144 is arranged on the outdoor fixed rod 113 and the wall to provide energy support for the operation of the intelligent fresh air system; the storage battery 145 is fixed inside the box body 111 to store the excess energy converted by the solar panel 144, so as to provide energy support for the operation of the intelligent fresh air system when there is not enough light converted into energy.

[0044] In the above embodiments, the sensor 141 includes a temperature sensor, a humidity sensor, a carbon dioxide sensor, and a PM2.5 sensor for monitoring indicators such as temperature, humidity, carbon dioxide concentration, and PM2.5 inside and outside the room. Four different sensors 141 are arranged on the installation box 15 to detect changes in indoor air indicators, and four different sensors 141 are arranged on the fixed rod 113 to detect changes in outdoor air indicators;

[0045] In the above embodiments, the controller 142 is disposed inside the box body 111 to automatically adjust the working state of the intelligent fresh air system according to the data monitored by the sensor 141 to keep the indoor air fresh; the controller 142 includes an indoor controller and an outdoor controller. The indoor controller is located at one end of the box body 111 close to the indoor, and is mainly responsible for receiving the monitoring results of various indicators of the indoor air by the indoor sensor. The outdoor controller is located at one end of the box body 111 close to the outdoor, and is mainly responsible for receiving the monitoring results of various indicators of the outdoor air by the outdoor sensor. The indoor controller and the outdoor controller will automatically adjust the working state of the intelligent fresh air system according to the air indicators transmitted by the indoor sensor and the outdoor sensor to ensure the circulation of indoor and outdoor air.

[0046] In the above embodiments, the variable speed driver 143 is disposed inside the box body 111 to control the rotation speed of the fan according to the detection results of the indoor and outdoor air indicators by the sensor 141 and the instructions of the controller 142, and only provides rotation when indoor and outdoor air intercommunication is required, and reduces the rotation speed of the fan as the indoor air quality improves, so that the energy storage battery 145 stores energy and reduces the noise of the fan.

[0047] Specifically, for the air intake and exhaust process, the solar panel 144 stores sufficient energy, and the sensor 141 detects various indicators in the indoor and outdoor air. When the indicators in the indoor air are higher than those in the outdoor air, the sensor 141 will trigger the controller 142 to work. The controller 142 controls the intelligent fresh air system to start working. The fan in the fresh air duct 121 inside the box body 111 starts to rotate, bringing the outdoor air into the indoor. The outdoor air passes through the filter plate 112 and the filter screen and enters the heating box, and then the fresh air and the stale air exchange temperature and humidity through the total heat exchanger to adapt to the temperature and humidity of the indoor air. Then, the converted fresh air is blown into the indoor by the fan in the fresh air duct 121 inside the installation box 15, and passes through the orifice cover 123 to blow the fresh air into the indoor in a divergent shape; the fan in the stale air duct 122 inside the installation box 15 draws the indoor air into the heating box to exchange the temperature and humidity of the stale air with that of the fresh air through the total heat exchanger, and then the fan in the stale air duct 122 inside the box body 111 drives the stale air in the heating box to blow out to the outdoor through the filter plate 112 of the stale air duct 122.
