Counter-current series-connection type efficient energy-saving fresh air ventilator

Abstract

The invention discloses a counter-current series-connection type efficient energy-saving fresh air ventilator. The structure of the counter-current series-connection type efficient energy-saving freshair ventilator comprises an air inlet, a case, an electric wire storage tank and an exhaust port. The case is provided with the air inlet and the exhaust port. The electric wire storage tank is connected with the case through bolts, the electric wire storage tank is provided with a tank frame, a winding assembly, a sliding walkway and a wire outlet sliding port, the tank frame and the case are fixed together, the winding assembly and the sliding walkway are arranged in the tank frame, the wire outlet sliding port is movably formed in the sliding walkway in a matched mode, the winding assemblyand the sliding walkway are coaxially installed, the winding assembly is provided with a shell, a power line, a leaf spring, a spring fixing frame, a clamping base, a plug and a guide roller, the power line is wound on the outer surface of the leaf spring, and the power line is fixedly provided with the plug. According to the counter-current series-connection type efficient energy-saving fresh air ventilator, the sliding walkway is matched with the winding assembly and wire outlets, and the power line can penetrate through the wire outlets, and the wire outlets are in sliding fit with the sliding walkway, so that the direction of the plug can be freely adjusted by the power line according to the directions of different extension sockets, and the flexibility is high.

Description

technical field [0001] The invention relates to the technical field of high efficiency and energy saving, in particular, it is a countercurrent series type high efficiency and energy saving fresh air fan. Background technique [0002] The vigorous development of modern urban construction, the high airtightness of urban buildings and the higher and higher heights of high-rise buildings have weakened the ventilation capacity of buildings themselves, and the ventilation of high-rise buildings has also become difficult due to the height of buildings and the rapid wind, while the indoor air The pollution situation is worrying. The poisonous and harmful gases such as formaldehyde and benzene released by home decoration, and the smoke from smoking cannot be discharged outside normally; Human health has caused great harm. Many people even have headaches, dry coughs, dry and itchy skin, dizziness, nausea, and difficulty concentrating. The importance of indoor ventilation and ventila...

Problems solved by technology

[0004] The purpose of the present invention is to provide a countercurrent series-type high-efficiency energy-saving fresh air fan, which is used to solve the problem that the existing fresh air blower avoids the problem that the exposed power cord is too long due to the power interface when the power cord is drawn out, and it is easy to trip the user. , in the fresh air fan, by setting multiple outlets and multiple wire slots, the power cord can be selectively drawn out from any outlet, and redundant power wires can also be stored through the wire slots, but multiple outlets The position of the port cannot be adjusted accurately according to the position of the power plug, and the flexibility is low; and it is difficult to reset the removed power cord during machine transportation, and the operation is time-consuming and laborious.
