Abstract
Provided is a fan of a structure with shutter blades and a rainproof elbow, the shutter and the rainproof elbow are arranged at an air inlet of the fan, the shutter is directly connected with the air inlet of the fan, the rainproof elbow is sleeved on the shutter and the air inlet of the fan and is connected with the fan body. According to the utility model, the fan has the functions of preventing wind from reversely blowing and rain water from entering into an air duct, and the utility model has advantages of simple structure, convenient mounting and dismounting, good wind reverse blowing-proof and rain water-proof effects.
Description
Technical field
The utility model relates to a kind of blower fan with louvre blade and rainproof elbow structure, belongs to the industrial fan product technical field.
Background technique
A large amount of at present ventilation blower fans in industrial use, its structure is that the blower fan body adds that motor and fan blade form, outside the blower fan decapacitation of this structure is ventilated and is used, when blower fan quits work, its blower fan inboard and the outside communicate, can't block, the easy like this impurity that causes carries out, and is unfavorable for health.
Simultaneously, the blower fan of this structure type is not owing to there is rainproof water-bound setting, so when raining heavily or during heavy rain, rainwater very easily is inhaled in the blower fan, the motor of blower fan is impacted or damages, bring influence for normal the use, also dangerous, may cause personal injury to the user of service.
Summary of the invention
The utility model provides a kind of a kind of blower fan with louvre blade and rainproof elbow structure of novelty, adopts self hang down type blinds gate and rainproof elbow structure are set, and closes the air channel automatically and prevents that rainwater from entering the purpose in air channel to realize blower fan.
The technical solution adopted in the utility model is:
A kind of blower fan with louvre blade and rainproof elbow structure, be provided with blinds gate and rainproof elbow structure at the intake grill place of blower fan, the blinds gate directly is connected with air inlet, and rainproof elbow is set on blinds gate and the air inlet, and is connected with the blower fan body.
The blade of blinds gate is the self hang down type structure, and the blinds gate is connected with the detachable structure of being connected to of air inlet.
Rainproof elbow is the curved shape tunnel structure, and rainproof elbow is connected with the detachable structure of being connected to of blower fan body.
The utility model beneficial effect is:
Owing to adopted a kind of blower fan of the present utility model with louvre blade and rainproof elbow structure, the intake grill place of blower fan is provided with blinds gate and rainproof elbow structure, make blower fan have and close the air channel automatically and prevent that rainwater from entering the function in air channel, have simple in structure, easy for installation, detachably, windproof refluence and anti-rainwater enter respond well characteristics.
Description of drawings
Fig. 1: be a kind of plan view of the utility model with blower fan of louvre blade and rainproof elbow structure;
Fig. 2: be a kind of left view of the utility model with blower fan of louvre blade and rainproof elbow structure.
Among Fig. 1: blinds gate 1, rainproof elbow 2.
Embodiment
As shown in Figure 1 and Figure 2.
A kind of blower fan with louvre blade and rainproof elbow structure comprises: blinds gate 1, rainproof elbow 2 structures.
Be provided with blinds gate 1 and rainproof elbow 2 structures at the intake grill place of blower fan, blinds gate 1 directly is connected with air inlet, and rainproof elbow 2 is set on blinds gate 1 and the air inlet, and is connected with the blower fan body.
The blade of blinds gate 1 is the self hang down type structure, and blinds gate 1 is connected with the detachable structure of being connected to of air inlet.
Rainproof elbow 2 is the curved shape tunnel structure, and rainproof elbow 2 is connected with the detachable structure of being connected to of blower fan body.
Basic functional principle: when blower fan starts use; wind enters in the blower fan by the rainproof elbow 2 and the blinds gate 1 of the curved tunnels shape of air inlet; and under the effect of blower fan blade, blow out from the front exhaust outlet; louvre blade when blower fan quits work in the blinds gate 1 will be sagging automatically; automatically close the air channel; simultaneously because rainproof elbow 2 is the curved shape tunnel structure; has barrier functionality; so rainwater can't enter in the blower fan when blower fan is worked, with the safety and the normal use of realization blower fan under harsh weather of protection blower fan.
