Description

Technical Field

[0001] The utility model belongs to the technical field of fresh air devices, and more specifically, relates to a fresh air device that automatically adjusts based on outdoor temperature. Background Art

[0002] A fresh air device is a device used for indoor air exchange, designed to introduce fresh air from outdoors and expel polluted air from the room, thereby improving indoor air quality and enhancing the comfort and health of the living or working environment.

In cities in the north, once the autumn and winter seasons come, the weather will get colder. Once the outdoor temperature is low, the fresh air device will deliver cold air into the room, causing the indoor temperature to drop sharply, which in turn affects the normal life of users.

[0004] Therefore, in view of this, the existing structure and deficiencies are studied and improved, and a fresh air device based on automatic adjustment of outdoor temperature is provided, in order to achieve a purpose with greater practical value. Utility Model Content

[0011] Further, the top end of the second rotating shaft penetrates through the upper end surface of the protective shell and is installed with an adjusting block.

[0012] Further, a controller is installed on an outer wall of one side of the outer shell.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] By the combined use of the temperature sensor and the electric auxiliary heating mechanism, when the temperature sensor monitors that the outdoor air temperature is relatively low, a start instruction is sent to the electric auxiliary heating mechanism through the controller to heat the air entering the room, so as to achieve the effect of automatically adjusting the temperature of the air entering the room according to the outdoor temperature.

[0015] By the combined use of the motor, the first rotating shaft, the rotating block and the scraper, during the operation of the fresh air device, the motor is started. The motor drives the rotating block to rotate through the first rotating shaft, and the rotating block drives a plurality of scrapers to rotate on the surface of the isolation net, so as to clean larger impurities such as leaves, plastic bags or insect corpses attached to the surface of the isolation net.

[0016] By the combined use of the adjusting block, the second rotating shaft, the gear and the rack, the adjusting block is rotated. The adjusting block drives the gear to rotate through the second rotating shaft, and the gear drives a pair of racks to move to both sides and insert into the U-shaped block, so as to fix the filter. Conversely, the filter can be disassembled by operating in the opposite way, and thus the purpose of quickly installing and disassembling the filter can be achieved.
