Benefits of technology

[0015]With the connection or disconnection between the sealing pad and the gasket, the nozzle hole can be opened or closed. Further, by overcoming the connecting force generated between the magnetic ring and the gasket, a stronger airflow can be generated.

Problems solved by technology

Thus, the hand of the user may feel ache after pressing the elastic ball body for a period of time.
On the other hand, the speed of pressing the elastic ball body is limited, so that it is impossible to generate a pressurized airflow strong enough to blow away the dust completely.
However, the nozzle is not provided with any means for preventing against the entrance of external air.
As a result, the dust just blown away may be sucked into the elastic ball body to jam the nozzle.
Further, the dust sucked in the nozzle may be blown out of the nozzle in the subsequent use to fall on the camera, the precise instrument, the lens or the keyboard.

Embodiment Construction

[0026]The detailed description and technical contents of the present invention will be explained with reference to the accompanying drawings. However, it should be understood that the drawings are illustrative only, but not used to limit the present invention.

[0027]Please refer to FIG. 1, which is an exploded perspective view showing an air blower of the present invention. The air blower includes an elastic ball body 100 provided with a nozzle hole 110 and a check hole 120 (as shown in FIG. 2), a nozzle 200 provided in the nozzle hole 110, and a check valve 300 provided in the check hole 120. A check portion 210 of the nozzle 200 is disposed into the elastic ball body 100 and tightly connected with the edge of the nozzle hole 110. The interior of the check portion 210 is provided with a stopping assembly 400 for blocking or opening the nozzle hole 110.

[0028]The elastic ball body 100 generally has an elastic plastic casing. The nozzle hole 110 and the check hole 120 are provided on t...

Abstract

The present invention provides an air blower relating to a cleaning device. The air blower includes an elastic ball body provided with a nozzle hole and a check hole, a nozzle disposed in the nozzle hole, and a check valve disposed in the check hole. A check portion of the nozzle is disposed into the elastic ball body and is tightly connected with the edge of the nozzle hole. The check portion is provided therein with a stopping assembly for blocking or opening the nozzle hole. With the stopping assembly provided at the nozzle hole, the nozzle hole is opened when the airflow within the elastic ball body is ejected out and closed when the external air enters the elastic ball body. In this way, the external air can be prevented from entering the air blower through the nozzle efficiently.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a cleaning device, in particular to an air blower for cleaning dust.[0003]2. Description of Prior Art[0004]An air blower is often used to blow away the dust in a camera, on a surface of a precise instrument or a lens, or in gaps of a keyboard.[0005]A conventional air blower includes an elastic ball body for receiving air, a nozzle and a check valve. The nozzle and the check valve are provided on two open holes of the elastic ball body respectively. When the elastic ball body is rapidly pressed by a user, the check valve blocks one of the two open holes, so that the airflow can be only allowed to pass through the other open hole to blow away the dust.[0006]Such an air blower has to be rapidly pressed by the user to generate airflow of sufficient pressure. Thus, the hand of the user may feel ache after pressing the elastic ball body for a period of time. On the other hand, the speed of pre...
