[0018] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0019] The embodiment of the utility model includes a ventilator 1, a shutter mechanism 2, a control system 3, a CO2 concentration detection system 4, a manual control system 5, a fire linkage system 6, a ventilation perforated plate 7 and a fireproof blocking plate 8.

[0020] The shutter mechanism 2 is installed at the air inlet of the ventilator 1 , and the shutter mechanism 2 includes a mounting plate 21 , a transmission rod 22 , shutters 23 , a motor 24 and a turntable 25 .

[0021] The mounting plate 21 is fixedly mounted on the ventilator 1. The louver 23 is rotatably mounted on the mounting plate 21, and the louver 22 can freely rotate 90°; the louver 23 is a plurality of pieces, arranged in sequence, with a center spacing of 28mm; the louver 23 is vertically arranged, with a size of 30mm*900mm*3mm, and is made of aluminum alloy. The transmission rod 22 is hinged to the upper end of the louver 23, and the transmission rod 22 connects all the louvers 23 together. The motor 24 is mounted in the side wall of the ventilator 1, and a turntable 25 is mounted on the output shaft of the motor 24, and the motor 24 is a stepping motor; one end of the transmission rod 22 extends into the side wall of the ventilator and is connected to the turntable 25. The motor 24 drives the turntable 25 to rotate, and the turntable 25 drives the transmission rod 22 to move left and right, and the transmission rod 22 drives the louver 23 to rotate, reaching an opening and closing range of 0-90°, completing the mechanical action from closing to fully unfolding. A rubber pad 26 is fixed on the side of the louver 23. When the louver 23 is closed, the rubber pads 26 of two adjacent louvers 23 are in contact, so that the sealing performance is better.

[0022] The control system 3 is connected to the motor 24 to control the operation of the motor 24 .

[0023] The CO2 concentration detection system 3 is installed indoors, and is connected to the control system 3 through built-in lines to detect indoor air. The control system 3 can control the motor 24 to rotate according to the different levels of indoor CO2 concentration based on the feedback information from the CO2 concentration detection system 3.

[0024] The control system 3 is connected to the fire linkage system 6, and the fire linkage system 6 can be connected to the building fire control system through built-in lines. According to the instructions of the fire control system, in the case of fire warning, the fire linkage system 6 will feedback the signal to the control system 3, and the control system 3 will actively control the motor 24 to close the shutter 23.

[0025] The control system 3 is connected to the manual control system 5 , which is provided with a knob 51 . By rotating the knob 51 , the manual control system 5 can feed back a signal to the control system 3 , and the control system 3 controls the motor 24 to drive the shutter 23 to open or close.

[0026] The ventilation perforated plate 7 is installed on both sides of the air inlet of the ventilator 1 and is located outdoors. The ventilation perforated plate 7 simultaneously plays the function of building exterior shaping and ventilator air intake, simplifying the common ventilator building structure form.

[0027] The ventilator 1 is often combined with the external curtain wall 9, and the hollow part of the shape is easy to form a micro chimney effect, which is easy to cause the spread of fire. Therefore, the utility model is provided with a fireproof blocking plate 9, which is fixed in the hollow part between the ventilator 1 and the external curtain wall 9 to eliminate the hidden danger of smoke and flames jumping through the hollow part to the upper building in the initial stage of the fire. The fireproof blocking plate 8 is made of galvanized steel plate.

[0028] The utility model has the following working modes:

[0029] Manual adjustment mode: The manual adjustment knob 51 is turned to a certain gear position, and the electrical signal is transmitted to the control system 3. The motor 2424 rotates, driving the transmission rod 22 to move. The shutter 23 adjusts the opening and closing angle under the traction of the transmission rod 22. After rotating to the preset gear angle, the motor 24 stops rotating.

[0030] Automatic adjustment mode: The CO2 concentration detection system 3 transmits the indoor CO2 concentration signal to the control system 3. If the CO2 concentration is greater than the preset value 1, the electrical signal is transmitted to the control system 3, the motor 24 rotates, drives the transmission rod 22 to move, and the louver 23 is adjusted to a 90° open state under the traction of the transmission rod 22. If the CO2 concentration is less than the preset value 2, the electrical signal is transmitted to the control system 3, the motor 24 rotates, drives the transmission rod 22 to move, and the louver 23 is adjusted to a minimum open state of 15° under the traction of the transmission rod 22, reducing the energy consumption of air conditioning while ensuring the necessary ventilation conditions. If the CO2 concentration is between the preset value 1 and the preset value 2, the motor 24 is controlled to adjust the louver 23 to an intermediate angle (the angle is calculated by interpolation).

[0031] Fire alarm mode: In case of fire danger, the fire linkage system 6 transmits the fire control electrical signal to the control system 3, the motor 24 rotates, and the shutter 23 is completely closed under the traction of the transmission rod 22, preventing the flames and smoke from jumping into the room through the external decorative cavity.

[0032] In addition, it should be noted that the shapes and names of the parts and components of the specific embodiments described in this specification may be different, and the above content described in this specification is only an example of the structure of the utility model. All equivalent changes or simple changes made based on the structure, features and principles described in the patent concept of the utility model are included in the protection scope of the utility model patent. Technicians in the technical field of the utility model can make various modifications or supplements to the specific embodiments described or replace them in a similar manner, as long as they do not deviate from the structure of the utility model or exceed the scope defined by the claims, they should all fall within the protection scope of the utility model.
