Description

Indoor gas production device

Technical Field

The utility model relates to an environmental monitoring analysis technical field, specific indoor gas production device that says so.

Background

The household environment is a man-made small environment for household agglomeration, rest, study and household labor, the condition of the household environment sanitation directly influences the morbidity and mortality of residents, for example, substances harmful to human bodies contained in indoor decorative materials, furniture and the like are released into the household and office environment to cause decoration pollution and the like. Environmental protection is more and more taken attention by people, but many people do not realize the influence of indoor environment quality on health, urban residents work, study and live indoors for about 90% of the whole day, some old people and children stay indoors for a longer time, and the room environment is closely related to human health and growth and development of children.

Consequently need regularly collect the detection to indoor environmental pollution thing, current gas production device needs artifical the collection, and work efficiency is lower, and complex operation, not only the gas production is slow, can not control the volume of gathering moreover, before carrying out the gas production, and the air in the gas production bag can't discharge completely, and gas mixture makes the testing result inaccurate when leading to follow-up gas production.

Therefore, the indoor gas collecting device is designed for overcoming the defects of the technology, has a simple structure, does not need manual collection, can quantitatively and quickly collect gas, is convenient to operate, can discharge the air in the gas collecting bag before gas collection, reduces the interference of other gases on the gas to be detected, and improves the reliability of a detection result, and is the problem to be solved by the inventor.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an indoor gas production device, its simple structure need not artifical the collection, can quantitative quick collection gas, and convenient operation can reduce other gaseous interference to the gaseous of awaiting measuring before the gas production with the air escape in the gas production bag, improves the testing result reliability.

The utility model provides a technical scheme that its technical problem adopted is: an indoor gas production device comprises a collection box body and a gas production bag, wherein a collection chamber and an air pump are arranged in the collection box body, a top cover on the collection box body is connected with the collection box body in a sealing manner, a pressure release valve is arranged on the top cover, the gas production bag is arranged in the collection chamber, a hose is connected onto the gas production bag, fixing plates are arranged on two sides of the top of the collection chamber, one end of each fixing plate is connected with the inner wall of the collection box body through a hinge, a containing cavity is formed between each fixing plate and the inner wall of the collection box body, an inserting hole for the hose to pass through is formed in the joint after the other ends of the fixing plates are mutually and tightly butted, a receiving piece is fixed onto the hose and is arranged on the mutually butted fixing plates and used for fixing the gas production bag, an electromagnetic valve and a flow sensor, the tail end of the hose is communicated with an air inlet formed in the collection box body, an extrusion plate is arranged at the bottom of the collection chamber, two ends of the extrusion plate are respectively connected with a pull rope, and the pull rope penetrates through the fixing plate.

Further, be provided with display screen, button on the collection box, button, display screen, air pump, flow sensor, solenoid valve are connected with the singlechip that sets up in the collection box respectively.

Furthermore, a ring is fixed at the tail end of the pull rope.

Further, the bottom of the bearing piece is covered with a rubber layer.

The utility model has the advantages that:

1. The utility model discloses a singlechip control adopts gas go on and close to control gas flow, need not artifical hard collection, can realize quantitative collection, device simple structure, convenient operation can upwards extrude the gas collection bag and will adopt the air escape in the bag through the stripper plate before adopting gas, reduces other gaseous interference to the gas that awaits measuring, improves the testing result reliability.
