Abstract
The utility model relates to a small flow rate gas controller with the functions of timing closing and accumulative measuring, comprising a timer, the rotary knob of the timer, an electromagnetic valve, a counter, an air inlet pipe, an outlet pipe, a mounting box body, and a connecting circuit. After energization, the utility model can implement the functions of the timing closing and accumulative measuring for small flow rate gas. The utility model can comprise the timer, the electromagnetic valve, the air inlet pipe, the outlet duct, the mounting box, and the connecting circuit as required for implementing the function of the timing closing for the small flow rate gas. The controller is mounted between gas passages. When the rotary knob of the timer is turned round, the electric circuit is on and the electromagnetic valve opens for passing through the gas. When the timing time expires, the electric circuit is off and the electromagnetic valve closes for blocking the gas. The utility model has the advantages of simple structure, less cost, and high durability, and the utility model can be used for the oxygen supply devices of families and business.
Description
Technical field
This utility model relates to a kind of switch controller of small-flow gas, especially a kind of have regularly close, the controller of stored count function, belong to the automatic control technology field.
Background technology
In recent years, along with the raising of people's living standard and people pursuit to healthy living, various domestic, business with oxygen supply equipment by more and more widely be applied to home oxygen therapy and oxygen uptake healthcare field.Oxygen inhaler becomes some asthma patients, the essential product of cardiovascular and cerebrovascular vessel patient's daily health caring and family emergency.
With regard to now, the oxygen uptake equipment of economy and durability mainly is made up of oxygen bottle, humidification bottle and airway, nasal obstruction etc.; in use the user is often reflected, when carrying out oxygen uptake night, falls asleep through regular meeting is involuntary; by the time wake up, the oxygen in the oxygen cylinder remains little.Excessive oxygen intake is harmful unhelpful, for to health of people and economic consideration, is badly in need of a kind of timing control apparatus to oxygen in the market, solves this problem.Therefore, produced this regularly small-flow gas controller of closing function that has, simultaneously, also can as required the stored count function be set.
Summary of the invention
Technical problem to be solved in the utility model is: small-flow gas is carried out the open and close controlling of gas circuit, and cumulative calculation opens and closes number of times.The technical scheme of being taked provide a kind of intervalometer, electromagnetic valve, enumerator, air inlet pipe, escape pipe, electric road connected mode.It is characterized in that: n intervalometer, a n electromagnetic valve, a n enumerator, a n air inlet pipe, a n escape pipe, n bar connecting circuit are set in described installation box body.
