Abstract

The utility model provides a ventilator hood, comprising a hood main body and a spring arranged on the hood main body. A handle is arranged on the hood main body, through which a user can easily take off the hood, which is convenient for the user to clean or repair the product.

Description

Ventilation fan cover

Technical field

The utility model relates to ventilation fan, especially relates to ventilation fan cover.

Background technique

Ventilation fan is a kind of ventilation equipment commonly used, usually can a face shield be set at the room ventilation mouth, is used to block the ventilation fan internal mechanism and provides carrier for the installation of light fixture.As shown in Figure 1, face shield 100 comprises the spring 120 on mask body 110 and the face shield, when cleaning or keep in repair ventilation fan, need take off with handgrip face shield 100.But as shown in Figure 1, four limits 130 of mask body 110 are plane and smooth structure, and there is the problem that is not easy to take off face shield in therefore easily sliding hand.

The model utility content

The purpose of this utility model is to provide a kind of ventilation fan cover, makes it to be convenient to dismounting, solves not allow easily detachable problem.

For achieving the above object, the utility model provides a kind of face shield of ventilation fan, comprise the spring on mask body and the face shield, it is characterized in that: on described mask body, set firmly handle, be used for when needs take off face shield, the operator can use handle to take off face shield easily, and cleaning or maintenance product make things convenient for customers.

Described handle is arranged on the brake pad of face shield side, is used to strengthen frictional force.

Described brake pad is one or more recess structure, can be the concave point that is recessed into or recessed.

Described brake pad is one or more protruding position structure, can be salient point or the raised line that protrudes.

Advantage of the present utility model is, easily the dismounting face shield.

Description of drawings

Fig. 1 is the known technology schematic representation;

Fig. 2 is the utility model first embodiment's schematic representation;

Fig. 3 is the utility model second embodiment's schematic representation.

Embodiment

As shown in Figure 2, be the utility model first embodiment's schematic representation.Face shield 100 comprises the spring 120 on mask body 110 and the face shield, and the both sides of mask body 110 all are provided with a plurality of recessed concave points 111.When cleaning or keep in repair, in the time that face shield 100 need being taken off, can push the both sides concave point 111 of mask body 110 with hand to ventilation fan, because the existence of concave point 111, increase frictional force, therefore can hold mask body 110 easily, so just taken off face shield 100 easily.

As shown in Figure 3, be the utility model second embodiment's schematic representation.Face shield 100 comprises the spring 120 on mask body 110 and the face shield, and the both sides of mask body 110 all are provided with the raised line 112 of a plurality of protrusions.When cleaning or keep in repair, in the time that face shield 100 need being taken off, can push the both sides raised line 112 of mask body 110 with hand to ventilation fan, because the existence of raised line 112, increase frictional force, therefore can hold mask body 110 easily, so just taken off face shield 100 easily.

Be concave point 111 or raised line 112 to be made a plurality of in the foregoing description, but also can refer to make one, perhaps other shape also can only be made roughened surface with the surface, as long as can increase frictional force.
