Abstract
The utility model discloses a novel protective cover of an electric fan, which comprises a front protective cover and a back protective cover. The front protective cover consists of a deflector ring and a plurality of grids, the cross section of each of the grids has a 'V'-shaped structure with the angle ranging from 105 degrees to 135 degrees and includes a first plane and a second plane, the first plane is connected to an air outlet end of the deflector ring distant from the back protective cover, the deflector ring consists of three sections spliced mutually, an air inlet end of the deflector ring close to the back protective cover is fastened with the outer edge of the back protective cover, the diameter of the deflector ring is reduced gradually from the air inlet end to the air outlet end, and the deflector ring is in the shape of a bell mouth integrally. Each of the grids has a bend angle capable of preventing a child extending fingers into blades to be hurt by the same. The deflector ring is capable of improving air supply efficiency and increasing air supply distance.
Description
Technical field
The utility model relates to a kind of electric fan, relates in particular to a kind of electric fan safety cover.
Background technique
Electric fan is the standing a kind of heat instrument that falls in every household in summer, and it is made up of head, flabellum, fuselage and safety cover.Fan in operation, the flabellum high-speed rotation, safety cover can be used to prevent that finger from stretching into fan and injured by flabellum.Particularly for child, because finger is thinner, active especially again, and that the fence of existing safety cover also can't be done is enough close, therefore, the accident generation of the finger of injuring is arranged in the time of still.Making a desirable safety cover becomes to attach most importance to.For example the model utility of Chinese patent document CN 201144850 Y discloses a kind of electric fan safety protection cover; Comprise the safety cover that is set in the electric fan protecting sheathing; The profile of safety cover and the protecting sheathing of electric fan are suitable; Be evenly equipped with mesh on the safety cover, and on the corresponding local safety cover of electric fan head, be provided with and tighten up mouth, tighten up mouth and be provided with the India rubber circle.The safety cover of the utility model is the reticulated work that very little mesh is arranged; Be enclosed within it on the electric fan containment vessel; Obviously can reduce the wind-force intensity of electric fan, be disadvantageous for original wind-force with regard to not too strong domestic electric fan, and this reticulated work is still pullled by active child easily.
Summary of the invention
The purpose of the utility model is to provide a kind of electric fan safety cover, not only can prevent effectively that child from stretching into finger in the fan and injured, and wind-force intensity is high, distance.
In order to achieve the above object, the utility model is realized through following technological scheme: a kind of electric fan safety cover comprises preceding safety cover, back safety cover; It is characterized in that, said before safety cover form by baffle liner and some grid sheets, it is " V " type structure of 105 °～135 ° that the cross section of said grid sheet is angle; Comprise first plane and second plane; Said first plane is connected on the outlet air end of baffle liner away from the back safety cover, and said baffle liner is spliced by three sections, and said baffle liner is near the outer clamping of air intake with the back safety cover of back safety cover; The diameter of said baffle liner is dwindled to outlet air end by air intake gradually, and baffle liner integral body is horn-like.When child will point when stretching in the fan from first plane, can be blocked by second plane, thereby can not be injured by flabellum, said baffle liner not only is convenient to the fixing of grid sheet, and can make air-flow obtain acceleration therein, has improved wind-force intensity and air supplying distance.
As preferably, said first plane and second plane included angle are 120 °.Can make wind farthest blow to the user like this through the grid sheet.
As preferably, said first plane and fan electromotor parallel axes.Can make the wind front blow to the user like this.
As preferably, the said first adjacent interplanar spacing is no more than 2 centimetres.Spacing is long, if will guarantee safety, will inevitably make the grid chip size excessive, and flabellum may be run in such second plane.
The beneficial effect of the utility model is: 1. safe and reliable, can prevent effectively that child from stretching into finger in the fan and by being wounded.2. baffle liner is the horn-like of tapered diameter and can increases wind-force, improves air supplying distance.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is a kind of sectional view of preceding safety cover.
Embodiment
Below in conjunction with concrete embodiment and accompanying drawing the utility model is further described.
Electric fan safety cover as shown in Figure 1; Safety cover 1, back safety cover 2 before comprising; Safety cover 1 is made up of baffle liner 3 and some grid sheets 4 before said; It is " V " type structure of 105 °～135 ° that the cross section of said grid sheet 4 is angle, comprises first plane 41 and second plane 42, and said first plane 41 is connected on the outlet air end 32 of baffle liner 3 away from the back safety cover.Among the embodiment shown in Figure 2; First plane 41 and fan electromotor parallel axes; It is " V " type structure of 120 ° that itself and second plane 42 are angle; The first adjacent interplanar spacing is 2 centimetres, as long as the width on second plane 42, just can guarantee that child's finger stretches into fan and blocked by second plane 42 when interior greater than 2.3cm.Said baffle liner 3 is spliced by three sections, and said baffle liner 3 is near outer 21 clampings of air intake 31 with the back safety cover 2 of back safety cover, and the diameter of said baffle liner 3 is dwindled to outlet air end by air intake gradually, and baffle liner 3 integral body are horn-like.Be spliced by three sections, the mechanical structure of experiment proof 3 stops is comparatively stable.Said baffle liner 3 can make air-flow obtain therein quickening; Can improve total head and the total pressure efficiency and the flow coefficient of domestic electric fan, overcome domestic electric fan and existed efficient lower, air quantity is not high; Defectives such as air supplying distance is not far, and then reached the effect that efficiency improves.Therefore the radius of the outlet air end 32 of baffle liner 3, can suppress the development in axial-flow leaf blade tip whirlpool greater than the maximum rotating radius of fan blade, can reduce the air-flow deflection angle of the fan blade of flowing through effectively simultaneously, thereby reduce the wastage.Air intake 31 has buckle, and the outer 21 of back safety cover 2 has bayonet socket suitable and the buckle clamping.
