Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0027] refer to figure 1 As shown, it is a three-dimensional structure diagram of the bladeless fan according to the embodiment of the present invention. The bladeless fan includes a base 101 for supporting the entire fan, a spherical base 102 fixed on the base, and a flat base fixed on the base. An elongated nozzle 103 . The nozzle 103 gradually shrinks from bottom to top, and is divided into left and right sides with larger areas, and front and rear ends with smaller areas, wherein the rear end is closed.

[0028] The illustrated nozzle 103 includes a tapered body 106 and a top trim 105 . The tapered body 106 has a tapered air channel inside, the rear end of the nozzle 103 is closed, and the front end is provided with...

Abstract

The invention discloses a bladeless fan. The bladeless fan comprises a bottom seat, a base and a nozzle; the base is positioned on the upper part of the bottom seat; the nozzle is fixed on the upper part of the base, has a flat and elongated shape, and is gradually reduced from bottom to top; an air guide vane is arranged in the air outlet of the nozzle; the air guide vane comprises transverse grills and longitudinal grills; the transverse grills are arranged in layers in the air outlet from bottom to top; the transverse grills distributed in the middle are short; the transverse grills on the upper part and the lower part are widened gradually; the longitudinal grills are connected with transverse grills of each layers and are arranged in bilateral symmetry. By the bladeless fan provided by the invention, the fan is safe and attractive, and an air flow with stability can be guided out.

Description

technical field [0001] The invention relates to a fan assembly, in particular to a bladeless fan. Background technique [0002] At present, a general household fan usually includes a driving device and a set of blades rotating around the center. The driving device moves the airflow by controlling the operation of the blades, thereby making the user feel cool. [0003] The forward flow of air produced by the blades of such fans cannot be felt uniformly due to variations across the blade surface or across the surface of the fan flush, due to a series of pulses or blows of air Interference, so the user will experience uneven or turbulent airflow. Variations across blade surfaces or across other fan surfaces may vary from product to product and may even vary from one individual fan to another. At the same time, this type of fan has parts protruding from the device, and the user can touch any part of the fan, so the safety performance of this fan is poor. Contents of the inve...
