I have designed a fan including a housing, a lanyard for suspending the fan, a circuit board placed in the housing, a fan unit, a battery, etc., the housing is provided with an air inlet and an air outlet, and the housing includes a front housing and The rear case is fixedly coupled to the front case, wherein the air inlet is disposed on the front case, and the air outlet is disposed at the top or the bottom of the case. The fan is provided with a protective member at the air inlet and the air outlet respectively, wherein the air inlet is provided with a protection net, and the protection net is fixed on the front shell by the snapping. Although the card is convenient for disassembly, the card is easily damaged and falls off. Therefore, the protection net cannot be firmly fixed to the front case.

[Summary of the Invention]

The technical problem to be solved by the present invention is to provide a fan in which the protection net is fixed firmly.

The object of the present invention is achieved by the following technical solutions: A fan includes a front case, an air inlet disposed on the front case, and a protection net fixed at the air inlet, the protection net being fixed to the front case by heat fusion At the air inlet.

Preferably, the air inlet is circular, the protection net is annular, and the front shell is provided with a buckle at the edge of the air inlet, and a corresponding card hole is arranged around the protection net, the buckle and the buckle After the hole is matched, it is fixed by hot melt at the buckle and the hole of the card. Fix it first by snapping it, then heat-fix it at the card joint to make it firmer.

Preferably, the air inlet is circular, the protection net is annular, and the front shell is provided with a buckle at the edge of the air inlet, and a corresponding card slot is arranged around the corresponding protection net, the buckle and the buckle After the card slot is matched, it is fixed by hot melt at the buckle and the card slot. Fix it first by snapping it, then heat-fix it at the card joint to make it firmer.

Preferably, the edge of the protection net is provided with an outwardly convex protrusion, and the card hole is disposed on the protrusion. Set the bumps to fit the front case.

Preferably, the bumps are at least two, and are evenly distributed around the protection net. Make it secure.

Preferably, the protrusion is disposed at the bottom of the protection net edge, and the outer surface of the front shell is provided with a convex edge protruding inward at the edge of the air inlet. The diameter of the protection net is equal to or smaller than the outer diameter of the convex edge, which is larger than the convex shape. The inner diameter of the edge, the protective net is placed on the convex edge. The protection net is placed on the convex edge, so that the front shell plays a certain limit on the protection net, which is convenient for fixing and makes the fit more tight.

Preferably, the outer edge of the protection net is provided with a concave recess which is recessed inward, the height of the concave opening is equal to the thickness of the convex edge, and the inner diameter of the concave opening is less than or equal to the inner diameter of the convex edge. The concave stop and the convex edge cooperate. This arrangement further complicates the protective mesh and the front casing and provides better limiting.

Preferably, the distance from the concave stop of the protection net to the bump is equal to the distance from the inner surface of the front shell to the convex edge. In this way, when the protection net is engaged with the front case, the bump and the front case can be contacted, so that the card hole and the buckle are better matched.

Preferably, the number of the bumps is eight, and is evenly distributed around the edge of the protection net. This is the specific number of sets of bumps.

In the invention, since the protection net is fixed to the air inlet of the front casing by heat fusion, since the heat fusion is firmly fixed, it is not loosened and is not easily damaged, so that the protection net is more firmly fixed on the front casing.

【detailed description】

The invention will now be further described with reference to the drawings and preferred embodiments. The invention discloses a fan, comprising a front shell, an air inlet provided on the front shell and a protection net fixed at the air inlet. As shown in FIG. 1 and FIG. 2, the protection net 1 is fixed to the front shell by heat fusion. 2 at the air inlet. In the present invention, since the protective net 1 is fixed to the air inlet of the front case 2 by heat fusion, since the heat fusion fixing is firm, it is not loosened and is not easily damaged, so that the protective net 1 is more firmly fixed to the front case 2.

In this embodiment, the air inlet is circular, the protection net 1 is annular, and the front shell 2 is provided with a buckle 21 at the edge of the air inlet, and the corresponding protection net 1 is provided with the buckle 21 The card hole 12, the buckle 21 and the card hole 12 are matched and then fixed by hot melt at the buckle 21 and the card hole 12. The protection net 1 has been fixed by the snap fit, and then the fuse is fixed at the card joint. Therefore, the protective net 1 is more firmly fixed to the front case 2 without worrying about the damage of the buckle 21 or the card hole 12. The card hole 12 described in this embodiment can also be replaced by a card slot, and the card slot and the snap 21 can cooperate to achieve the same effect.

In this embodiment, the edge of the protection net 1 is provided with an outwardly convex protrusion 11 , the card hole 12 is disposed on the protrusion 11 , and the protrusion 11 is disposed to facilitate the cooperation with the front case 2 , the protrusion 12 is at least two, and is evenly distributed around the protection net 1. The number of the specific bumps 11 is eight, and is evenly distributed around the edge of the protection net 1, so that the fixing is firm.

In this embodiment, the protrusion 11 is disposed at the bottom of the edge of the protection net 1, and the outer surface of the front case 2 is provided with an inwardly protruding convex edge 22 at the edge of the air inlet, and the diameter of the protection net 1 is equal to or smaller than The outer diameter of the flange 22 is greater than the inner diameter of the flange 22, and the protective mesh 1 is placed on the flange 22. In addition, the outer surface edge of the protection net 1 is provided with a concave recess 13 which is recessed inward, the height of the concave opening 13 is equal to the thickness of the convex edge 22, and the inner diameter of the concave opening 13 is less than or equal to the convexity. Along the inner diameter of 22, the recess 13 and the rim 22 cooperate. Therefore, through the above cooperation, the protection net 1 is placed on the convex edge 22, and the front casing 2 plays a certain limiting role on the protection net 1, which is convenient for fixing, and the cooperation is further improved by the cooperation of the concave opening 13 and the convex edge 22. close.

In this embodiment, the distance from the concave opening 13 of the protection net 1 to the protrusion 11 is equal to the distance from the inner surface of the front casing 2 to the convex edge 22, so that when the protection net 1 is engaged with the front casing 2, The bump 11 is in contact with the front case 2 to better fit the card hole 12 and the buckle 21.

The invention can also directly fix the protection net on the front shell by heat fusion, without setting buckles and card holes Cooperation. It is also possible to securely protect the protection net. It is to be understood that the specific embodiments of the invention are limited only by the description. It will be apparent to those skilled in the art that the present invention can be made without departing from the spirit and scope of the invention.
