Fan convenient to blow cold wind in summer

Abstract

The invention discloses a fan convenient to blow cold wind in summer. The fan convenient to blow the cold wind in summer comprises a box, wherein a support seat is arranged above a base and is connected and fixed with the base through a lifting mechanism; the box is connected to the upper end of the support seat through a rotating mechanism; a storage tank is arranged on the bottom part in the boxand is used for storing ice cubes; openings are formed in the positions, on the left side and the right side of the storage tank, of the box; a fixed outer cover is connected to the upper end of thebox through an air guiding pipe; and a motor is fixed to the left end surface of the fixed outer cover. The fan convenient to blow the cold wind in summer provided by the invention is simple and reasonable in structure; the storage tank is arranged on the bottom part in the box and is used for storing the ice cubes, and fan blades are rotated under the drive of the motor, so that negative pressureis produced on the right side surfaces of the fan blades, and outside air can enter from the inner part of the box and then enters the fixed outer cover along the air guiding pipe; and air flows through the fixed outer cover so as to take away cold air on the ice cubes, so that wind blown out by the fan blades is cold wind, the problem of poor cooling effect of an existing fan is solved, and thepracticability is high.

Description

technical field [0001] The invention relates to the technical field of energy-saving and environment-friendly equipment, in particular to a fan for blowing cold air in summer. Background technique [0002] In the hot summer, we are already inseparable from the air conditioner, but the air quality inside the air-conditioned room is very poor, and we cannot turn off the air conditioner, which makes us in a dilemma. [0003] In addition, there are many problems caused by the use of air conditioners. For example, the required electricity is large, which leads to the improvement of people's living standards. In addition, the refrigerant in the air conditioner, Freon, is a gas that is harmful to the environment. Although fluorine-free air conditioners are advocated, But the improvement in real life is not very big. [0004] The use of air conditioners is actually because the effect of electric fans is not obvious. In view of the above problems, a fan is now provided that is conve...

Problems solved by technology

[0007] A fan that is convenient for blowing cold air in summer, including a box body, a support seat is arranged above the base, the support seat and the base are connected and fixed by a lifting mechanism, the upper end of the support seat is connected to the box body through a rotating mechanism, and the bottom of the box body is provided with The storage tank is used to store ice cubes. There are openings on the boxes on the left and right sides of the storage tank. The upper end of the box is connected with a fixed outer cover through an air duct, and a motor is fixed on the left end of the fixed outer cover. There is an output shaft, and the end of the output shaft is provided with fan blades. The left end of the fixed outer cover is fixed with a No. 1 protective frame. The left side of the No. 1 protective frame is connected to the No. 2 protective frame through a connecting flange. The No. 2 protective frame indicates uniform distribution of ventilation There is a vent hole on the fixed outer cover where the No. 1 protective frame is located, and the fixed outer cover is connected with the box body. Driven by the motor, the fan blade rotates, so that negative pressure is generated on the right side of the fan blade, so that the outside air It will enter from the inside of the box, and then enter the fixed outer cover along the air duct. When the air flows through the fixed outer cover, it will take away the cold air on the ice, so that the wind blown by the fan blades is cold air, which solves the problem of existing fans. The problem of poor cooling effect
