Minitype air-supply machine

Abstract

The invention relates to a small size air feeder, comprising a motor and an air making mechanism, which is characterized in that the outlet of the air making mechanism is connected with an air cylinder; the air making mechanism is arranged in parallel with the motor; both the air making mechanism and the motor are arranged in the casing; the air outlet of the outlet pipe on the air cylinder is arranged on the front of the casing and the handle is arranged on the casing top. The small size air feeder has the advantages that the stable and controllable airflow can be obtained and can be controlled with the pneumatic switch; during working, the air making mechanism can be automatically started or stopped depending on the internal air pressure; the air pressure can be constant without manual operation and the machine can not be started or stopped frequently due to actual need of the air source, so the operation is very easy. The whole structure is compact with beautiful appearance and convenient for carrying, the obtained air source is high quality without impurity and moisture content, The small size air feeder has little noise and thus can meet the standard requirement of below 47decibel stipulated in developed countries.

Description

technical field [0001] The invention relates to an air supply machine, in particular to a small-sized air supply machine used in the use situation where the air volume needs to be controlled more accurately. Background technique [0002] Existing small gas supply machines generally include a motor with a shaded pole structure, a gas generator and an air outlet pipe. The outlet of the gas generator is directly connected to the outlet pipe, and the motor is connected to the eccentric balance weight and connecting rod through a shaft to transmit the power of the motor For the air-making mechanism, the connecting rod reciprocates up and down in the cylinder under the eccentric action of the balance weight. When moving downward, the intake valve opens and the exhaust valve closes to suck air into the cylinder. When the connecting rod moves upward, The air valve is closed, and when the air in the cylinder is compressed to a certain extent, the exhaust valve is opened to discharge ...

AI Technical Summary

Problems solved by technology

[0003] The above-mentioned small gas supply machine has the following disadvantages: 1. The gas after gas generation is used directly, and the air flow is sometimes large and sometimes small and unstable, and if the entire volume is reduced for the convenience of carrying, the gas supply is insufficient, and it is difficult to meet the large gas consumption. Requirements, if in order to ensure the gas consumption and gas pressure, a larger motor and gas generating mechanism are required, resulting in a larger volume of the whole machine, which is inconvenient to carry

2. There is no buffer for the air outlet, and it is directly controlled by the machine's start and stop. Often, due to the intermittent opening and closing of the machine, a relatively uniform air flow cannot be obtained, and the working pressure cannot be displayed, and the working air pressure cannot be adjusted, so it cannot be used for precise control of air flow. Speed ​​and dosage use environment, such as as a small air supply machine

3. There is no automatic stop and start function. When the inkjet pauses in the middle, you can only turn off the power by hand in time, and turn it on again when you need to use gas. The operation is more troublesome

4. It is not equipped with an intake filter and a noise reduction device, so it is difficult to obtain a high-quality air source with no impurities, no moisture, and stable air pressure

When it is used in an inkjet printer, there is no oil-water separator between the air outlet and the inkjet pen. Even if an oil-water separator is installed, the oil-water separator can only be installed in the front of the air outlet pipe due to its large volume, and the oil-water separator cannot be installed. The water in the trachea between the airbrush and the airbrush is discharged, and some water still enters the airbrush pen to affect the spray painting effect

5. The noise is loud, which affects the mood of the user, especially when a quieter working environment is required, such as an inkjet printer used as an artist, it will affect people's emotions and affect work efficiency and effect

It is difficult to meet the standard requirements of less than 47 decibels stipulated by developed countries
