Abstract

The utility model discloses an air guide structure of a ventilator, which comprises a shell, wherein an air guide opening is arranged at the front end of the shell and comprises an outer inclined surface, a plurality of rotating surfaces are arranged on the outer inclined surface, a protective cover is arranged outside the air guide opening, and the rotating surfaces extend to the protective cover. The utility model has the following advantages and effects: through setting up the swivel plane in the border position to set up the annular piece of slope on the guard shield, this wind-guiding structure can agree with the rotatory wind that takes place that is taken out by the flabellum, thereby increases the smoothness nature of air-out.

Description

Air guide structure of ventilator

Technical Field

The utility model relates to the technical field of ventilation fans, in particular to an air guide structure of a ventilation fan.

Background

The ventilating fan is an air-conditioning electric appliance which uses a motor to drive fan blades to rotate so as to drive air flow and make indoor and outdoor air exchange. Also known as a ventilation fan.

The opening part of the ventilator is provided with an air guide port, and the air guide port and the ventilator are integrally arranged conventionally, and the air guide port has a certain radian so as to ensure the stability of air outlet.

The outside of ventilation fan is provided with the protection casing to when the ventilation fan is used, the user can not stretch into the flabellum with the health part by mistake and cause the damage, guarantees the security that the ventilation fan used.

In the prior art, the air outlet of the air guide port and the protective cover are easy to impact, and the smoothness of the air outlet is affected.

Disclosure of Invention

The utility model aims to provide an air guide structure of a ventilator with good air outlet smoothness.

The technical aim of the utility model is realized by the following technical scheme: the utility model provides an air guide structure of scavenger fan, includes the casing, and the casing front end is provided with the air guide mouth, and the air guide mouth includes the external ramp, is provided with a plurality of swivel facial features on the external ramp, is provided with the protection casing outward the air guide mouth, and the swivel facial features extends to the protection casing.

Further provided is that: the protection casing includes a plurality of concentric annular pieces, is provided with the connecting rod between the annular piece.

Further provided is that: the annular piece is arranged in a relatively outwards inclined expansion way.

Further provided is that: the inclination angle of the annular sheet is between 20 and 40 degrees.

Further provided is that: the rotating surface is smoothly connected with the annular piece of the outermost ring.

In summary, the utility model has the following beneficial effects: through setting up the swivel plane in the border position to set up the annular piece of slope on the guard shield, this wind-guiding structure can agree with the rotatory wind that takes place that is taken out by the flabellum, thereby increases the smoothness nature of air-out.

Drawings

Fig. 1 is a perspective view of an air guiding structure of a ventilator.

In the figure: 1. a housing; 2. an air guide port; 3. an outer inclined surface; 4. a rotating surface; 5. a protective cover; 6. an annular sheet; 7. and (5) connecting a rod.

Detailed Description

The present utility model will be described in further detail with reference to the accompanying drawings.

The utility model provides an air guiding structure of scavenger fan, includes casing 1, installs the flabellum that drives with rotating motor in the casing 1. The front end of the shell 1 is provided with an air guide opening 2, the air guide opening 2 is an annular outer inclined surface 3, the outer inclined surface 3 expands outwards, and the inner side is a plane. I.e. as shown in fig. 1, an inclined outer bevel 3 is provided on the inner wall of the front end of the housing 1. The outer inclined surface 3 is provided with a plurality of rotating surfaces 4, and the rotating surfaces 4 extend outwards and are connected with a protective cover 5.

A protective cover 5 is arranged outside the air guide opening 2 on the shell 1. The protection cover 5 is a plurality of concentric annular sheets 6, and the rotating surface 4 extends outwards to one annular sheet 6 at the outermost layer and is connected smoothly between the two annular sheets. The annular sheets 6 are connected with each other through connecting rods 7, the sections of the connecting rods 7 are circular, the number of the connecting rods 7 is preferably four, a two-horizontal two-vertical cross structure is adopted, and the annular sheets 6 are fixed on the connecting rods 7 so as to realize the stability of the protective cover 5.

The ring segments 6 on the shield 5 are flared obliquely outwards, with an angle of inclination between 20-30 degrees, preferably 25 degrees.

This scavenger fan blows out wind through the flabellum when using, because traditional flabellum can be rotatory with the wind formation of taking out when rotating, the wind-guiding structure of this application can pass through the rotatory wind of rotation plane 4 agreeing with in the border position to increase the velocity of flow of wind in the side, guarantee the smoothness and smoothness of air-out.

Meanwhile, in the middle position of the air outlet, the inclined annular piece 6 can also ensure a rotary air outlet mode, and due to the inclination of the annular piece 6, the air outlet mode with outward expansion can be matched and guided, so that the air outlet smoothness is improved while the air is ensured to be stabilized.

The present embodiment is only for explanation of the present utility model and is not to be construed as limiting the present utility model, and modifications to the present embodiment, which may not creatively contribute to the present utility model as required by those skilled in the art after reading the present specification, are all protected by patent laws within the scope of claims of the present utility model.
