Description

Technical Field

[0001] This utility model relates to the technical field of fresh air blowing devices, specifically a fresh air blowing device for an air purifier. Background Technology

[0002] A fresh air system is an independent air handling system consisting of a supply air system and an exhaust air system. It is divided into two types: ducted fresh air systems and ductless fresh air systems. A ducted fresh air system consists of a fresh air unit and ductwork fittings. The fresh air unit purifies outdoor air and introduces it into the room, while fresh air is supplied through exhaust ducts installed on the pipes. However, in existing fresh air purifiers, the fresh air outlets are usually oriented in one direction. Since the fresh air is introduced from the outside, even after passing through a heat exchanger, a temperature difference still exists between the indoor and outdoor air. Prolonged blowing of fresh air in one direction can lead to uneven indoor temperature. This is especially problematic for people with weakened immune systems, as the temperature difference can cause discomfort and potentially lead to other illnesses. Therefore, preventing the discomfort caused by consistently blowing air in one direction is an area that air purification equipment needs improvement. Thus, a fresh air blowing device for air purifiers is needed to solve this problem. Utility Model Content

[0014] Example 1

[0015] like Figures 1 to 3 As shown, this utility model discloses a fresh air blowing device for an air purifier. The technical solution includes an air outlet pipe 1 and a telescopic corrugated pipe 2. A mounting ring 101 is fixedly sleeved at the rear end of the air outlet pipe 1. The mounting ring 101 has a fixing hole 102. Several opening and closing louvers 103 are rotatably arranged from top to bottom inside the air outlet pipe 1. The ends of the opening and closing louvers 103 are connected by meshing gears. An adjusting screw 107 is rotatably arranged on the right side of the air outlet pipe 1 for adjustment. Screw 107 is connected to one of the gears at the end of the louver 103. By adjusting screw 107, the gear of the louver 103 is rotated, which changes the inclination of the louver 103 and thus the air volume. A positioning ring 104 is fixedly sleeved on the middle of the outer side of the air outlet duct 1. A connecting sleeve 201 is fixedly installed on the rear end of the telescopic corrugated pipe 2. The connecting sleeve 201 is sleeved on the air outlet duct 1 and is located in front of the positioning ring 104. The telescopic corrugated pipe 2 is made of plastic. The air outlet duct 1, mounting ring 101, positioning ring 104, and connecting sleeve 201 are all made of stainless steel. The air outlet duct 1 has evenly spaced connecting screw holes 105 on its side. The connecting sleeve 201 has fixing screws 202 on its side that mate with the connecting screw holes 105. The installation method using the connecting screw holes 105 and fixing screws 202 facilitates the disassembly of the connecting sleeve 201. A connection is provided between the air outlet duct 1 and the connecting sleeve 201. The rubber pad 106 prevents fresh air from leaking from the interface. The air outlet duct 1 connects to the air supply duct, thereby outputting the fresh air from the air supply duct. The air outlet duct 1 is fixed to the air supply duct by the mounting ring 101 and the fixing hole 102 in conjunction with the external screw. The air volume inside the air outlet duct 1 can be controlled by opening and closing the louvers 103. The telescopic corrugated pipe 2 facilitates changing the air outlet direction. The connecting sleeve 201 facilitates the disassembly of the telescopic corrugated pipe 2 for maintenance.

[0016] The working principle of this utility model is as follows: Install the air outlet pipe 1 to the opening of the air supply pipe, use an external screw to pass through the fixing hole 102, install the mounting ring 101 on the air supply pipe to fix the air outlet pipe 1, the air supply pipe delivers fresh air inside, and the fresh air is output from the air outlet pipe 1. Turning the adjusting screw 107 can change the inclination of the opening and closing louver 103 and change the air volume of the air outlet pipe 1. When it is necessary to change the air outlet direction, stretch one side of the telescopic corrugated pipe 2, and then the telescopic corrugated pipe 2 will tilt to the other side, and the air outlet direction will be to the other side.
