DETAILED DESCRIPTION

[0020] In order to make the content of the utility model more clearly understood, the utility model is further described below based on specific embodiments in combination with the accompanying drawings.

[0021] It should be noted that the terms "center", "upper", "lower", "front", "back", "left", "right", "inner", "outer" and the like used herein to indicate directions or positional relationships are based on directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. Unless otherwise specified, "plurality" means two or more.

[0022] Unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood by specific circumstances.

[0023] The utility model relates to an intelligent fresh air system, which is a fresh air system that realizes intelligent regulation based on pressure detection.

[0024] Specifically, Figure 1 and Figure 2As shown, the intelligent fresh air system 1 may include: a control module 11, a fan module 12, an air supply duct 13 and a pressure feedback module 14. The fan module 12 is used to generate fresh air flow and transport it to the building 2 through the air supply duct 13. The pressure feedback module 14 is arranged in the air supply duct 13 and is used to obtain the pressure data of the air supply duct 13. The control module 11 is electrically connected to the pressure feedback module 14 and the control module 11 controls the working state of the fan module 12 based on the pressure data. In the present utility model, the operation of the fan module 12 is adjusted by utilizing the pressure change of the air supply duct caused by closing the indoor fresh air function or the fresh air window when people are not indoors, thereby realizing intelligent control, reducing power consumption, and improving energy conservation and environmental protection.

[0025] In some examples, such as Figure 2 As shown, the pressure feedback module 14 may include a plurality of pressure measuring devices 141, and the plurality of pressure measuring devices 141 are distributed at different positions in the air supply duct 13. In this case, the pressure at different positions of the air supply duct 13 can be measured, thereby improving the accuracy of regulating the operation of the fan module 12.

[0026] In other examples, the pressure measuring device 141 may also be replaced by a wind speed measuring device. The wind speed measured by the wind speed measuring device may also be converted into wind pressure. For example, when people close the fresh air window, the wind speed of the corresponding air supply channel will immediately drop (pressure increase), and thus the operation of the fan module 12 may be adjusted by the control module 11 based on the wind speed change in the air supply channel.

[0027] In some examples, such as Figure 1 As shown, the fan module 12 may include a constant oxygen fan 121 for generating a fresh air flow and a purification device 122 connected to the constant oxygen fan 121 and used for purifying the fresh air flow. In this case, the freshness and cleanliness of the delivered air can be guaranteed.

[0028] In some examples, there are multiple constant oxygen blowers 121 and purification devices 122. In this case, the ability to deliver fresh air can be improved.

[0029] In some examples, the functions of the purification device 122 mainly include filtering dust, disinfecting viruses and sterilizing bacteria.

[0030] In some examples, such as Figure 2 and Figure 3As shown, the control module 11 may include a PLC controller 111 and multiple switches 112. The PLC controller 111 controls the working states of multiple constant oxygen fans 121 or multiple purification devices 122 through the switches 112 based on the pressure data. In this case, through the PLC controller 111 and the multiple switches 112, it is possible to intelligently turn on or off multiple constant oxygen fans 121 or purification devices 122, thereby improving the real-time, intelligent, and automated degree of the intelligent fresh air system 1.

[0031] In the present invention, the PLC controller 111 is used for control instead of the computer system, which can also reduce the unnecessary programming of computer system control programs or system delays, thereby improving the degree of real-time.

[0032] In some examples, such as Figure 4 As shown, the fan module 12 may also include a heating device 123 connected to the constant oxygen fan 121 and used to heat the fresh air flow. In this case, when the temperature is low, such as in winter, heating can also be provided when fresh air is delivered, thereby reducing the cost of additionally setting up a heating device.

[0033] In some examples, such as Figure 4 As shown, the intelligent fresh air system 1 may further include a temperature detection module 16 for detecting the ambient temperature of the building 2, and the control module 11 controls the working state of the heating device 123 based on the ambient temperature. In this case, the heating device 123 can work more accurately and further improve intelligence.

[0034] In some examples, the arrangement order of the constant oxygen blower 121, the purification device 122 and the heating device 123 may not be limited to the following. Figure 4 As shown, for example, the air may be first extracted by the constant oxygen blower 121, and then heated and purified by the purification device 122 and the heating device 123; the air may also be first purified by the purification device, and then transported by the constant oxygen blower 121 and heated by the heating device 123. That is, the arrangement order of the constant oxygen blower 121, the purification device 122 and the heating device 123 may be limited.

[0035] In some examples, such as Figure 1 or Figure 4 As shown, the intelligent fresh air system 1 may further include an exhaust duct 15, the exhaust duct 15 having multiple outlets and at least one of the multiple outlets being connected to the purification device 122. In this case, the exhaust duct 15 may be connected to the purification device 122 to realize fresh air circulation, that is, it is possible to reduce the amount of outdoor air drawn by the constant oxygen fan 121, thereby further improving the effect of energy saving and environmental protection.

[0036] The embodiments described above are only preferred implementation modes of the present utility model and cannot be used to limit the protection scope of the present utility model. Any non-substantial changes and modifications made by technicians in this field on the basis of the utility model shall fall within the protection scope of the present utility model.
