Description

The ventilating fan structure

Technical field

The utility model relates to is a kind of ventilating fan structure, particularly be a kind of provide aesthetic in appearance and ventilating fan practicability.

Background technique

Existing ventilating fan is with the framework internal fixation motor and fan blade to be arranged, and it utilizes motor to drive the fan blade rotation by the power source driving motor, can reach the effect of air draft.

But, existing ventilating fan, structure is quite simple, is looked by outward appearance, and described fan blade is directly exposed outside, even does not have screen frame protected, and when having foreign matter to be involved in fan blade because of carelessness, easily causes danger; Especially, the child that some are young, can because curiosity order about following, directly touch fan with hand, and cause the injury that can't retrieve at high speed rotating.

Therefore, how above-mentioned defective is forgone, be the place of the technical difficulties of this case model utility designer institute desire solution.

Summary of the invention

The purpose of this utility model: be to provide a kind of ventilating fan structure, in order to overcome above-mentioned defective.

For realizing its purpose, the technical solution adopted in the utility model is, a kind of ventilating fan structure is provided, and it comprises: pedestal, motor, blade; Described pedestal inboard is provided with fixed support, and described fixed support provides the interlocking motor, motor the place ahead winding blade, and between motor and blade, be provided with bearing, the exhaust port place of described pedestal is provided with valve jacket and wire side again; Moreover described pedestal is like curved tubular structure, and has respectively towards the two ends of different direction, and an end is an exhaust port, and an end is an intake grill, and at intake grill place combination venetian blind, also can utilize shutter blade to adjust the air-flow wind direction; By above-mentioned member, make the utility model have concurrently aesthetic in appearance and ventilating fan structure practicability.

The beneficial effects of the utility model are compared with the prior art, and ventilating fan structure of the present utility model not only has external form structure attractive in appearance, by pedestal motor and blade are coated in it again, form protection, can avoid because curious, directly touch blade in the rotation with hand; Moreover the motor front end also is provided with bearing, and wherein said bearing is arranged in the middle of blade and the motor, makes on its structure more firmly, when revolution, drives the blade rotation by bearing, can reduce spoilage, also increases its serviceability.

Embodiment

Below in conjunction with accompanying drawing, to this novel above-mentionedly is described in more detail with other technical characteristics and advantage.

At first see also shown in Figure 1, a kind of ventilating fan structure of the utility model, when it is implemented:

Fig. 1 is STRUCTURE DECOMPOSITION figure of the present utility model, shown in the figure, a kind of ventilating fan structure 1, it is the ventilating fan that is applied in the building air-conditioning, have the function of smooth attractive in appearance and practicability of external form concurrently, be primarily characterized in that: described pedestal 10 inboards are provided with fixed support 11, described fixed support 11 provides interlocking motor 20, motor 20 the place ahead winding blades 30, and be provided with bearing 21 at

motor

20 and 30 in blade, the exhaust port place of described again pedestal 10 is provided with valve jacket 31 and wire side 32, and the intake grill place of pedestal 10 is provided with venetian blind 12.

See also Fig. 2 constitutional diagram of the present utility model, described pedestal 10 is like curved tubular structure, and has respectively the two ends towards different direction, one end is an exhaust port, one end is an intake grill, and at intake grill place combination venetian blind 12, can utilize shutter blade to adjust the air-flow wind direction; The curved appearance of pedestal 10 makes the utility model present modern stylishness, the type body that visually has smoothness attractive in appearance in outward appearance.

See also Fig. 3 perspective view of the present utility model; a kind of ventilating fan structure of the utility model; by pedestal 10 motor 20 and blade 30 are coated in it, form protection, also be provided with bearing 21; it is middle with motor 20 that wherein said bearing 21 is arranged on blade 30; make on its structure more firmly, when motor 20 rotates, drive blades 30 rotations by bearing 21; can reduce spoilage, also increase its serviceability.

See also Fig. 4 and Fig. 5, it is respectively another structural perspective of the present utility model and sectional view, be to provide a kind of ventilating fan structure, it comprises: described pedestal 10 inboards are provided with motor 20, motor 20 the place ahead winding blades 30, the two ends of pedestal 10 are respectively intake grill and exhaust port, the exhaust port place of described again pedestal 10 is provided with valve jacket 31 and wire side 32, and the intake grill place of pedestal 10 is provided with an inside casing 40, described inside casing 40 provides to put and filters lamellar body 41, and the outside of filtering lamellar body 41 is in conjunction with a venetian blind 12.

Wherein said filtration lamellar body 41 can be a filter cotton sheet, and it has the function that purifies air, and reaches the working life that prolongs motor 20 and blade 30 simultaneously, to reduce the number of times of maintenance service.

In sum, the utility model is being broken through under the previous technical pattern, has reached the effect that institute's desire is promoted really, and also non-familiar described skill person is easy to obtain; Moreover not open before the utility model application, the progressive of its tool, practicability show the application important document that has met novel patent, propose novel application in accordance with the law.

More than explanation is novel just illustrative for this; and it is nonrestrictive; those of ordinary skills understand; under the situation of the spirit and scope that do not break away from following claims and limited; can make many modifications; change, or equivalence, but all will fall in the protection domain of the present utility model.
