Problems solved by technology

[0004] Considering that there are more or less deficiencies in the existing fan technology, such as using blades to supply air, the comfort of the wind is not very good due to its own characteristics, and there are certain safety hazards; for bladeless fans, Although it solves the problem of safety hazard and air comfort, it is difficult to increase the air volume and wind speed of this type of fan, because when the air flows in its internal cavity, it will inevitably generate vortices due to its internal shape. loss of energy and pressure

Embodiment Construction

[0021] The present invention will be clearly described below in conjunction with accompanying drawing:

[0022] combine figure 2 , image 3 , Figure 4 , Figure 6 and Figure 7 Description of the air supply part: the output shaft of the motor 11 is connected to the input end of the coupling 2, the output end of the coupling 2 is connected to the left end shaft of the screw 3, and the shaft is fixed on the coupling with a set screw 9 , the shaft and the screw 3 are integrated, and the rotation of the motor 11 can drive the screw 3 to rotate together. When the screw 3 is viewed from right to left in the space formed by the screw housing 4 and the screw housing cover 5, the clockwise rotation is forward rotation, according to Figure 4 , Figure 6 , Figure 7 When the screw 3 rotates forward, any air passing through the center section of the screw 3 is being pushed by the screw 3 to move from left to right, and the air flows from the air inlet to the air outlet from a ma...

Abstract

The invention discloses a portable electric screw fan which is mainly used for cooling people in summer. The fan comprises a circuit power supply part, an air supply part, screws, fastening screws, anupper shell and a lower shell. Circuit parts are connected in sequence to form a loop, and the loop of a circuit is composed of a charging loop, a boosting voltage-stabilizing loop and a motor driving loop. According to the air supply part, a motor drives a screw rod to rotate in a certain space to promote air to flow from an air inlet to an air outlet in a pressurized manner. The fan has the beneficial effects that the air outlet comfort is better; the noise is lower; the outlet air volume is larger; the wind speed can be steplessly adjusted, and the requirements of different crowds under different conditions can be met; and the size is smaller, carrying is convenient, and certain cruising ability is achieved.

Description

technical field [0001] The invention belongs to the technical field of fans, and relates to the fields of electrical electronics and air pumps. Background technique [0002] In today's society, hand-held portable fans have become a very important tool for people to cool down in summer. At the same time, many different products have been derived, such as silent fans, bladeless fans, human-driven fans, etc., or in the fan Add some other functions on the basis of the original functions. [0003] When people use a fan, they will consider some performances of the fan, such as the comfort of the air outlet, the volume of the air outlet, the speed of the air outlet, the noise generated by the fan, and so on. [0004] Considering that there are more or less deficiencies in the existing fan technology, such as using blades to supply air, the comfort of the wind is not very good due to its own characteristics, and there are certain safety hazards; for bladeless fans, Although it sol...
