Embodiment

As shown in Figure 1, do not have among the embodiment of blade fan at the utility model, it mainly is made up of three parts, and promptly main body 4, and lay respectively at main body 4 tops go out vane 1 and base 19, wherein, main body 4 is as the main mounting structure of this no blade fan, and this main body 4 is provided with whole circle intake grill, in the embodiment in figure 1, the shape of this main body 4 is tubular constructions, and it can be cylinder, square tube and other shape.For the setting of intake grill, can be on the side of the main body 4 of tubular construction, along same horizontal position a plurality of intake grills are set, thereby form whole circle intake grill.The impeller that motor 28 is set in the inside of main body 4 and is connected with motor 28, impeller are connected on the running shaft that extends outward from motor 28, thus can be after connecting power work impeller rotation generation suction, outside air can be sucked from intake grill.For the installation of motor 28, in this embodiment, carriage 5 is set in main body 4 especially, and then motor 28 is arranged on the carriage 5.Further, in order to strengthen the shockproof effect of this no blade fan, carriage 5 is to be fixed in the main body 4 by shockproof pin 7 and shockproof seal ring 30.In order to make motor 28 when working, what the noise of generation can be less spreads out of, and also is provided with Sound-proof material 8 in the bottom of main body 4.

As shown in Figure 1, between main body 4 inherent motor 28 and the intake grill water conservancy diversion air channel is set, this water conservancy diversion air channel can with air-flow upwards guiding enter going out in the vane 1 of main body 4 tops, after in air-flow enters out vane 1, constantly rotational flow is full of the secondary gas flow air channel in the vane 1, produce the baric area, the air channel that goes out thus in the vane 1 is the secondary booster air channel, in the process of the air-flow rotating boosting in this secondary booster air channel, the part air-flow can be overflowed from the exhaust outlet that goes out on the vane 1, in order to make that overflowing air-flow forms upwards and soft naturally wind direction and wind-force, shown in Fig. 2 A, at parallel wind-guiding face 41 that the position is provided with and the air-out air-flow parallels that goes out vicinity exhaust outlet on the vane 1 and the oblique wind-guiding face 40 angled with the air-out air-flow, it can not change airflow direction effect by this parallel wind-guiding face 41, and can change original direction and oblique water conservancy diversion by the part air-flow that oblique wind-guiding face 40 can be extruded exhaust outlet, the upwards air-flow of diffusion can be provided thus, thereby the air-flow of pulling side and back is operation forward together, and can be the user and provide nature soft cool effect.

As shown in Figure 7, the structure for going out vane 1 can be designed as annular solid, also can be other shape, and is for example square, ellipse etc.In this embodiment, this goes out vane for marking circular body.Shown in Fig. 2 B, be provided with seal ring 30 in the joint that goes out between vane 1 and the main body 4, thereby make this no blade fan have the effect of anti-air-flow sinuous flow.Shown in Fig. 2 C, the joint between carriage 5 and the main body 4 also is provided with shockproof seal ring 31.

Shown in Fig. 3 and 4, main body 4 be can before and after be arranged on rotationally on the base 19, the plan view with exhaust outlet that is defined as shown in Figure 7 for the fore-and-aft direction of main body 4 is a forward direction, the rear view direction of this plan view be afterwards to.In this embodiment, the angle that main body 4 is rotated forward is not more than 10 degree and the angle that rotates backward also is not more than 10 degree, thereby under the drive of main body 4, goes out the rotation of vane 1 before and after can realizing.As shown in Figure 4, for this rotating mechanism, it mainly comprises the slick and sly tooth-like part 51 with continuous groove and has the positioning part 52 of the projection that the groove with tooth-like part 51 is complementary.By the effect of external force, the projection of regulating this positioning part 52 is arranged in which groove of tooth-like part 51, thus the rotation before and after realizing.Among the embodiment as shown in Figure 4, this tooth-like part 51 has 9 grooves, when the projection of positioning part 52 is positioned at intermediate groove, this goes out vane 1 and main body 4 is in normal erectility, thereby can be forward and regulate three gears backward in this positioning part 52, the angle that each gear is regulated is 3.3 degree, with each three kinds of different angles of inclination and normal upright angle before and after realizing.

Shown in Fig. 1,5 and 6, but this base 19 is arranged on the adjusting base on the fixed base with comprising fixed base and left rotation and right rotation.In a preferred embodiment, regulate base and be not more than 45 degree and dextrorotary angle also is not more than 45 degree to the angle of anticlockwise.For rotating machinery, its mainly by transmission arm 13, wave motor 14, chute 10, land 20 and POM axle 16 and 3pcs slide plate 32 is formed.In addition, be provided with Rubber foot 17 and knob and button PCB assembly 11 in the bottom of pedestal 19.

The utility model describes by several specific embodiments, it will be appreciated by those skilled in the art that, under the situation that does not break away from the utility model scope, can also carry out various conversion and be equal to alternative the utility model.In addition, at particular condition or concrete condition, can make various modifications to the utility model, and not break away from scope of the present utility model.Therefore, the utility model is not limited to disclosed specific embodiment, and should comprise the whole mode of executions that fall in the utility model claim scope.
