Problems solved by technology

However, most of the bladeless electric fans on the market currently adopt a vertical structure, and the diameter of the main body cylinder is much smaller than the diameter of the fan head. In this way, the fan can only be placed on a hard surface such as a table, and it is easy to accidentally touch it. Dumping; coupled with the high center of gravity caused by the height of the electric fan, the vibration is too large and more unstable when the motor rotates

Embodiment Construction

[0014] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0015] see figure 1 , the present invention provides a technical solution: a bladeless electric fan, including a motor 4 and an air outlet ring 1, characterized in that: the bottom of the air outlet ring 1 is provided with a base 8, and the top of the motor 4 is provided with a louver 3. The motor 1 is fixed on the base 8 through the support 11 and the hook sleeve 5. The right side of the support 11 is located on the motor 4 with a rotor support 10, and the tw...

Abstract

The invention discloses a bladeless electric fan, comprising a motor and an air outlet ring, a base is arranged at the bottom of the air outlet ring, a louver fan is arranged on the top of the motor, and the motor is fixed on the base through a support and a hook sleeve , the right side of the support is located on the motor with a rotor pillar, the two ends of the top of the motor are respectively connected to the air outlet ring through the air duct, the two sides of the motor are respectively provided with anti-slip sheets, and the left side of the base is provided with Intake hole. By changing the original vertical type into a horizontal type, the previous shortcoming of a large head and a small body has been improved, so that even if it is placed on a soft base such as a bed, it is not easy to tip over and is more stable. The wind in the ring is tangent to the air outlet ring, so that the wind speed entering the air outlet ring basically does not slow down, thereby ensuring that the pressure in the air outlet ring can increase rapidly, increasing the wind speed, and saving energy. It is good for shock absorption and reduces noise.

Description

technical field [0001] The invention relates to the field of home appliances, in particular to a bladeless electric fan. Background technique [0002] An electric fan is referred to as an electric fan, also known as a fan or a fan. It is a household appliance that uses a motor to drive the fan blades to rotate to accelerate the circulation of air. It is mainly used for cooling, relieving heat and circulating air. Widely used in homes, offices, shops, hospitals and hotels and other places. The electric fan is mainly composed of fan head, fan blade, net cover and control device and other components. The fan head includes a motor, front and rear end covers, and an oscillating air supply mechanism. The main components of the electric fan are: AC motor. Its working principle is: the energized coil is forced to rotate in the magnetic field. Electrical energy is converted into mechanical energy, and at the same time due to the resistance of the coil, a part of the electrical en...
