Description

A low-cost, high-airtight, controllable air supply system

technical field

The invention belongs to the field of mechanical equipment, in particular to a low-cost, high-airtight and controllable air supply system.

Background technique

The currently used controllable air supply system mostly uses syringes. There is a certain amount of air leakage between the syringe barrel and the piston of the commonly used syringe. If the amount of supplementary air is exceeded, the error is very large. If an airtight syringe is used, the price of each is more than several hundred yuan, which significantly increases the cost of the product.

In the practice of air supply system selection and application, it is found that the existing air supply system cannot meet the needs of practical applications in terms of air tightness and cost. Therefore, a controllable air supply system with low cost and good air tightness is urgently needed gas device.

The object of the present invention is to provide a low-cost, high-airtight and controllable air supply system aiming at the defects of the prior art.

In order to achieve the above purpose, the present invention adopts the following technical solutions: a low-cost, high-airtight controllable gas supply system, including: a control component, a stepping motor, a transmission component and a gas generating component;

Wherein the gas generating assembly includes a spring bottle and a bracket, the spring bottle includes a bottle body and a gas pipe, the bottle body is fixed by a bracket, the bottom of the bottle body is connected to a stepping motor through a transmission assembly, and the stepping motor rotates under the control of the control assembly, Drive the transmission assembly to push the bottom of the bottle body to compress the spring bottle or retreat to restore the spring bottle to its original shape.

The control component includes a single-chip microcomputer and a driving circuit, the single-chip microcomputer controls the speed and the number of rotations of the stepping motor, and the driving circuit provides suitable voltage and current for the stepping motor.

The transmission assembly includes a screw rod, a nut and a connecting rod; the stepping motor is connected to the screw rod, the nut is sleeved on the screw rod, and the connecting rod is connected to the nut.

Described connecting rod comprises connecting plate in the middle part and the connecting rod at connecting plate two ends, and the area of connecting plate is identical with the bottom of spring bottle, and is fixed on the bottom of spring bottle, and connecting rod is fixed on the nut by bolt respectively.

The screw rod is fixed by bearings arranged at both ends.

The stepper motor is connected to the screw rod, the nut is set on the screw rod, the connecting plate of the connecting rod is fixed on the bottom of the spring bottle, and the connecting rods are respectively fixed on the nut by bolts. When the control component controls the stepper motor to rotate clockwise or counterclockwise, The rotation of the screw rod drives the nut to move forward or backward, and the forward or backward movement of the nut drives the movement of the bottom of the spring bottle, so that the spring bottle is compressed or restored to its original shape.

Compared with the separate structure of the syringe and the piston, the spring bottle is an integrated structure, and there is no problem of air leakage. At the same time, the output gas volume of the spring bottle is controllable through the control assembly, stepping motor, and transmission assembly.

The low-cost, high-air-tight and controllable air supply system of the present invention solves the air leakage problem of the air supply system, and at the same time, because of the low cost, safety and controllability, it also solves the bottleneck difficulty in the commercialization of the air supply system.
