Description

Guided air filter

The present invention relates to a guide type air filter, in particular to a suction end that can be coupled to any air compressor by using a body with a lock seat, and a spiral guide member is disposed inside the body, and Providing at least one filter element, and combining a cap with the body, and forming an air inlet space between the screw cap and the body; thereby, when the air compressor is started, the external air enters the body by the air inlet space of the screw cap After filtering impurities (such as dust, particles, etc.) in the air through the filter element, the air is discharged from the lock seat through the guide member, so that the filtered air can perform air with multiple advantages of smoothness, stability and low noise. Filter function.

Press, air compressor or inflator can be mainly used in various fields of pneumatic tools, vehicle tires or various aerators, as a source of gas pressure or power; in particular, emergency charging requirements for car tires and recreational ATVs In the field of filling and venting equipment, or even in DIY's own hands-on field, the role of air compressors has long been a necessary gas supply equipment for these areas or general household repairs.

As for the working principle of the air compressor, the compressor is directly driven by the electric motor to make the crankshaft of the compressor produce a rotary motion, thereby driving the connecting rod to cause the piston to reciprocate, thereby causing the cylinder volume to change, thereby obtaining pressure or Powerful compressed air.

In addition, in the demand for air compressors, such as tire inflation, ATV tire charging and discharging, etc., there is a demand for air intake filter. In order to avoid sucking in a lot of gravel or dust, the inflator is highly depleted. The problem is that the service life is reduced. The conventional air compressor is placed at the air inlet end, and a simple air filter device is provided to filter the gravel or dust in the air.

The air filter device provided by the conventional air compressor is directly installed in the air compressor in a fixed manner. Therefore, it is known that the air filter device of the air compressor cannot be disassembled to replace the internal filter material, and even more The installation is suitable for other air compressors; in addition, the air flow path of the air filter device of the conventional air compressor is designed in a straight line manner, which leads to the internal air filter device of the conventional air compressor, which is easy to form a flow turbulence In this case, the air filter device of the conventional air compressor is inevitably causing serious noise and poor air intake.

Therefore, how to provide an air filter that can be combined with the air intake end of any air compressor and that can be aired in a smooth, stable and low noise mechanism is the main problem to be solved by the creative office.

The guide air filter disclosed in the present invention comprises a body, a guide member, a sealing member, a pressure plate, at least one filter element and a screw cap. The body is provided with a spiral guiding groove in the accommodating space, the spiral guiding groove is provided with a first air inlet and a first air outlet, and the body extends with a locking seat at the bottom thereof, and the first air outlet of the spiral guiding groove is The hollow portion of the lock seat is formed to communicate with each other; the guide member is a soft material and is overlapped and sleeved in the spiral guide groove, the guide member is provided with a second air inlet and a second air outlet, and the second inlet The air port is located at the same position as the first air inlet, and the second air outlet is at the same position as the first air outlet; the sealing element is a soft The sheet body is overlaid on the guide member to form a sealing function; the press-fit gas plate is disposed above the sealing member, and is provided with a plurality of air inlet holes and an air outlet passage, and the plurality of air inlet holes communicate with the air outlet passage, And the air outlet channel is in communication with the first air inlet and the second air inlet; at least one filter element is disposed above the pressure air plate to cover the plurality of air inlet holes of the pressure air plate to form an air filtering function. The screw cap covers the opening above the accommodating space, the diameter of the screw cap is larger than the diameter of the opening, the screw cap has at least two corresponding claw members protruding on the inner wall surface thereof, and the screw cap is on the inner wall surface thereof and is rotated An air inlet space is formed between the claw members, and the screw cover is coupled to the outside of the opening of the body by the claw member, so that a space is formed between the air inlet space of the screw cover and the body for air to enter.

The technical feature of the present invention is that the lock seat of the body can be combined with the air inlet end of any air compressor. When the air compressor is started, the external air can enter the space of the body through the air inlet space of the screw cover, through the filtering. After the component filters impurities (such as dust and particles) in the air, the air enters through the plurality of air inlet holes of the pressure plate and flows out through the air outlet passage, and the air is guided to the first air inlet and the second air inlet. The air is guided in a spiral manner to the first air outlet and the second air outlet through the guide member, and then flows to the hollow portion of the lock seat. Finally, the filtered air is discharged and transported to the air pressure by the hollow portion of the lock seat. In this way, through the lock seat, the body can be coupled to the intake end of any air compressor; in addition, through the guide member provided inside the body, the air can be achieved by smooth, stable and low noise mechanism. Effectively filters the air entering the air compressor.
