Abstract

The utility model discloses a blast blower which comprises a spiral case, an electric motor on one side of the spiral case and an electric control box, a support is arranged on the bottom of an outer shell of the electric motor. The utility model is more scientific and safer than the prior blast blower.

Description

A kind of blower

1, technical field:

The utility model relates to a kind of blower.

2, background technique:

Existing blower comprises volute, be positioned at the motor of volute one side and be used for settling the electric control box of motor electrical control components and parts.In the volute lower end, a supporting portion is generally arranged, supporting whole blower, electric control box is contained on the shell of motor.The blower of this structure has its deficiency: 1) supporting portion is located under the volute usually, but the weight ratio volute of motor wants big, the center of gravity deflection motor of blower, and the blower of this structure is crank often, topples over easily; 2) electric control box that is used for installing motor electrical control components and parts is set separately, be convexly equipped with on the shell of motor, through using out of doors for a long time, damage appears in the shell of electric control box easily, this not only can influence the motor electrical control components and parts in the electric control box, more likely produces the danger of getting an electric shock.

3, summary of the invention:

In order to overcome the deficiencies in the prior art, the purpose of this utility model provides a kind of scientific structure, blower safe in utilization.

The utility model is achieved by the following technical solution:

A kind of blower comprises volute, is positioned at the motor of volute one side, and wherein the outer casing bottom of motor is provided with a supporting base.Its advantage is: because the center of gravity of blower deflection motor, supporting base be positioned at motor below, can make blower be difficult for toppling over directly at the center of gravity lower support, structure is science more.

One cavity is arranged in the above-mentioned supporting base, and motor electrical control components and parts are installed in the cavity.Its advantage is: motor electrical control components and parts are installed in the supporting base, have saved the space and the material that separately electric appliance control box are set and use, and motor electrical control components and parts are well protected.

4, description of drawings:

Below in conjunction with accompanying drawing the utility model is done detailed explanation:

Fig. 1 is a rear view of the present utility model;

Fig. 2 is the A-A generalized section of Fig. 1;

Fig. 3 is a three-dimensional exploded view of the present utility model.

5, embodiment:

Embodiment: as Fig. 1, Fig. 2, shown in Figure 3, the utility model comprises volute 1 and is positioned at the motor 2 of volute one side that motor is covered with motor housing 3.Motor housing 3 bottoms are provided with a supporting base 4.Whole blower can be supported by supporting base 4.One cavity 8 is arranged in the supporting base 4, and motor electrical control components and parts 5 (as electrical switch, electric capacity or other components and parts) are installed in the cavity 8.

Claims (3)

1. a blower comprises volute and the motor that is positioned at volute one side, it is characterized in that: the motor housing bottom is provided with a supporting base.

2. a kind of blower according to claim 1 is characterized in that: a cavity is arranged in the described supporting base.

3. a kind of blower according to claim 2 is characterized in that: the electrical control components and parts of motor are installed in the cavity of supporting base.
