Problems solved by technology

[0004] However, for some parts with complex shapes, small volumes, and many undulating surfaces (such as mobile phone casings), during the continuous blowing process, the wind force is relatively lacking in explosive power, so it is difficult to remove the accumulation on the parts. The dust and impurities in the crevices, the dust removal effect is relatively poor, and it is not easy to achieve the purpose of complete dust removal

Embodiment Construction

[0014] In order to make the content of the present invention clearer, the following specific examples are given as examples in which the present invention can actually be implemented.

[0015] figure 1 is a schematic diagram of a blower device according to a preferred embodiment of the present invention. see figure 1 , the blower device 100 includes a control circuit 110 and an air filter (Air Filter) 120 . Wherein, the control circuit 110 includes a cycle control circuit 111 and a solenoid valve 113 . After receiving the input power, the cycle control circuit 111 will turn on and off the solenoid valve 113 correspondingly in turn according to the first time period and the second time period respectively within the total time period. Since the air filter 120 is coupled to the solenoid valve 113, when the solenoid valve 113 is in a conduction state within the first time period, the air filter 120 will be driven to filter the air, and the air will pass through, for example, a...

Abstract

The invention relates to a blowing device and a control circuit thereof, wherein, the control circuit can change the conduction state along with a time period, an electromagnetic valve is further controlled to be repeatedly switched between the two states of turn-on and cut-off, the blowing device is controlled to alternately carry out the two actions of blowing and stopping in the total time period, thus achieving the purpose of enhancing the wind strength during each blowing. In addition, the switch of the states can allow the blowing device to be converted to the blowing mode which does not stop generally, thus allowing the blowing device to be more flexible on the usage.

Description

technical field [0001] The present invention relates to a control circuit of a blowing device and a blowing device using the above-mentioned control circuit, and in particular relates to a blowing device capable of supporting two modes of direct and intermittent blowing and the control circuit thereof. Background technique [0002] For electronic product manufacturers, during the manufacturing process of electronic products, some parts obtained from upstream parts manufacturers may have dust or impurities attached to the parts during their manufacture or delivery. Most of these dust impurities will affect the quality of the product. Therefore, before the manufacturers of electronic products use these parts to assemble products, they must first dedust the parts to remove unnecessary impurities, and then use them in product manufacturing. among. [0003] Generally speaking, the method of dust removal is to blow the parts through a blowing device, and remove the dust and impur...
