Abstract
A wind shield ring in a blade-free fan comprises an upper ring shell and a lower ring shell which are integrally molded, the lower ring shell is in a barrel shape, the upper ring shell is in a flared shape and is buckled on the lower ring shell, the small opening of the upper ring shell is arranged as a wind outlet and is internally provided with a plurality of air flow separation sheets, preferably, four to eight air flow separation sheets are arranged, and the air flow separation sheets are uniformly arranged in the radial direction. The outer wall of the lower ring shell is provided with a plurality of positioning clamp buckles and a plurality of screw holes, so as to conveniently position and install the wind shield ring in a base at the bottom of the blade-free fan. During working, a fan in the base at the bottom of the blade-free fan rotates to push air flow to enter the wind shield ring, the air flow gathers together in the barrel-shaped lower ring shell and the flared upper ring shell, the air flow enters a wind pipe through the wind outlet at the small opening of the upper ring shell in a radiating way, then the air flow is blown out through a wind opening at the head part of the fan, when the air flow enters the wind pipe in a radiating way, the air flow separation sheets in the small opening of the upper ring shell can block the rotation of the air flow, the upward potential energy of the air flow is increased, and the effect of the air flow entering the wind pipe in a radiating way is better.
Description
Technical field
The utility model belongs to without the blade fan technical field, specifically relates to a kind of without the wind loop in the blade fan.
Background technique
Without blade fan because safe and practical, be loved by the people, be arranged on without the blower fan of blade fan in the pedestal of bottom, the air-flow that the blower fan rotation promotes could blow out via the air port of fan head through long airduct, therefore needs wind loop to gather when air-flow enters airduct and radiates air-flow.In the prior art, the wind loop structural design is very unreasonable, gathers and to radiate the effect of air-flow not good enough.
Summary of the invention
The utility model mainly is to solve the existing technical problem of above-mentioned prior art, provides a kind of without the wind loop in the blade fan.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of without the wind loop in the blade fan, described wind loop comprises integrated upper circle shell and lower circle shell, lower circle shell is tubbiness, upper circle shell is horn-like and buckles on lower circle shell, and the osculum of upper circle shell is set to exhaust outlet; Be provided with several locating fasteners and several screw holes on the lower circle shell outer wall, be convenient to the wind loop location and installation in without the blade fan bottom base.
As preferably, some air-flow cutting plates are set in the osculum of described upper circle shell, the air-flow cutting plate evenly radially arranges.
As preferably, in the described upper circle shell osculum 4-8 sheet air-flow cutting plate is set.
During work, promote air-flow without the rotation of the blower fan in the blade fan bottom base and enter wind loop, under tubbiness, gather in circle shell and the horn-like circle shell, then entering into airduct through the radiation of the exhaust outlet at upper circle shell osculum place blows out via the air port of fan head again, air-flow also has the air-flow cutting plate barrier air rotation in the circle shell osculum when radiation enters into airduct, strengthened the upper punch potential energy of air-flow, it is better that radiation enters into the effect of airduct.The utlity model has the characteristics such as simple in structure, reasonable in design.

Fig. 1 is a kind of main TV structure schematic representation of the present utility model;
Fig. 2 is a kind of side-looking structural representation of the present utility model;
Fig. 3 is a kind of plan structure schematic representation of the present utility model;
Fig. 4 is a kind of perspective view of the present utility model.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: referring to Fig. 1～4, the utility model is without the wind loop in the blade fan, comprise integrated upper circle shell 2 and lower circle shell 1, lower circle shell 1 is tubbiness, upper circle shell 2 is horn-like and buckles on lower circle shell 1, and the osculum of upper circle shell 2 is set to exhaust outlet 4, and some air-flow cutting plates 6 are set in the osculum of upper circle shell 2,4-8 sheet air-flow cutting plate preferably is set, and the air-flow cutting plate evenly radially arranges.Be provided with several locating fastener 3 and several screw holes 5 on lower circle shell 1 outer wall, be convenient to the wind loop location and installation in without the blade fan bottom base.
During work, promote air-flow without the rotation of the blower fan in the blade fan bottom base and enter wind loop, under tubbiness, gather in circle shell and the horn-like circle shell, then entering into airduct through the radiation of the exhaust outlet at upper circle shell osculum place blows out via the air port of fan head again, air-flow also has the air-flow cutting plate barrier air rotation in the circle shell osculum when radiation enters into airduct, strengthened the upper punch potential energy of air-flow, it is better that radiation enters into the effect of airduct.The utlity model has the characteristics such as simple in structure, reasonable in design.
At last, should be pointed out that above embodiment only is the more representational example of the utility model.Obviously, the utility model is not limited to above-described embodiment, and many distortion can also be arranged.Every foundation technical spirit of the present utility model all should be thought to belong to protection domain of the present utility model to any simple modification, equivalent variations and modification that above embodiment does.
Claims (3)
1. one kind without the wind loop in the blade fan, it is characterized in that described wind loop comprises integrated upper circle shell and lower circle shell, and lower circle shell is tubbiness, and upper circle shell is horn-like and buckles on lower circle shell, and the osculum of upper circle shell is set to exhaust outlet; Be provided with several locating fasteners and several screw holes on the lower circle shell outer wall.
