Abstract
The utility model relates to a pressure automatic control device of an inflator, and is used with the inflator so as to control the air pressure of the inflating product. The utility model has the technical proposal that the pressure automatic control device of the inflator comprises a shell and a control circuit which is arranged in the shell. The utility model is characterized in that the shell is provided with an air pressure checking mouth connected with the inflating product and a vent; a pressure inductor in the control circuit checks the air pressure signal of the product to be compared with the given norm voltage so as to control the work of the inflator. The air pressure controller controls the air chamber pressure of the inflated product in a certain pressure; when the power is switched on, the inflator inflates automatically; when the pressure of the air chamber is of the given control pressure, the inflator automatically stops; when the pressure is not enough and lower than the given pressure, the inflator automatically starts; when the pressure in the air chamber exceeds the given pressure, the inflator automatically discharges the air until the pressure reaches the given pressure.
Description
Technical field:
The utility model belongs to automation field, relates to a kind of inflator automatic pressure control device.
Background technology:
Aerated product is through the research and development of many decades and the progress of raw material, and market is more and more general, and its kind comprises seabeach series products (as air cushion), inflation advertisement article (as advertising balloon) and inflation massage article (as the inflation massage cushion) or the like.And existing being used for generally all do not have pressure control device to the inflator of these product inflations, can not set maximum inflation pressure.If inflate experience because of carelessness or not, through regular meeting aerated product is exploded, or filled to such an extent that too full formation is leaked gas, badly influence the quality of aerated product.This very big with the process error of feeling to charge and discharge the gas operation.Concerning some pressure required more accurate aerated product, general inflator was just not really suitable.
Summary of the invention:
The purpose of this utility model provides a kind of inflator automatic pressure control device, and it cooperates inflator to use together, can control the air pressure of aerated product, accomplishes robotization control.
This gas pressure regulator is controlled at the air chamber pressure of the later product of inflation in certain pressure.Just automatically inflation during opening power, when the pressure of air chamber during at the controlled pressure of setting, pump stops automatically.When insufficient pressure was lower than set pressure, pump started automatically; When the pressure in the air chamber surpasses the pressure of setting, lose heart till the pressure of setting automatically.
The technical solution of the utility model is: a kind of inflator automatic pressure control device, include shell and cased control circuit, it is characterized in that having on the shell air pressure that connects aerated product and detect mouth and exhausr port, control circuit is connected with inflator by interface; Pressure inductor compares with the reference voltage of setting by the air pressure signal of testing product in control circuit, and then the work of control inflator.
Inflator pressure control device provided by the utility model is simple in structure, easy to operate, uses the air pressure that can control aerated product effectively with inflator, is applicable to industry, the products for civilian use such as advertising balloon, inflation massage bolster.
Description of drawings:
Fig. 1 is an enclosure interface synoptic diagram of the present utility model.
Fig. 2 is circuit theory diagrams of the present utility model.
Fig. 3 is physical circuit figure of the present utility model.
Embodiment:
As shown in Figure 1, this inflator automatic pressure control device comprises shell 1, and the interface 2 that links to each other with inflator is equipped with in the left side of shell 1, and the right side is a power interface 3.Be provided with at the downside of shell 1 and charge and discharge gas pilot lamp 6, also be provided with the air pressure that is used to detect aerated product air pressure and detect mouthfuls 4 and the exhausr port 5 of exhaust when being used for the satiety of product air pressure.Flexible pipe connects air pressure and detects mouthfuls 4 and be connected aerated product with a flexible pipe respectively with exhausr port 5 during use, and formation is to the air pressure monitor of product.
Fig. 2, Fig. 3 are respectively circuit theory diagrams and the physical circuit figure that this control device adopts.
When inflated condition: inflation motor entry into service inflation after power on circuitry, VR1 sets a reference voltage, when product is inflated to full gas, the signal that SENSOR senses compares to ICA4 after ICA2 and ICA3 amplify, sensing signal voltage is during as the reference voltage that sets greater than VR1, Q2 and Q1 can move by conducting RELAY, and the inflation motor can shut down.Inflation motor entry into service again when pressure is low to moderate reference voltage when aerated product has gas leakage.
When deflated state: the aerated product internal pressure can rise when daytime temperature raises, the signal that SENSOR senses compares to ICB4 after ICB2 and ICB3 amplify, VR2 sets a reference voltage, when reference voltage that the signal that senses sets greater than VR2, Q3 can move the discharge of the air in the product by the conducting solenoid valve, and product can be because of pressure rising explosion.The reference voltage of VR1 and VR2 is set on the product size and is decided.
Claims (1)
1. an inflator automatic pressure control device includes shell and cased control circuit, it is characterized in that having on the shell air pressure that connects aerated product and detects mouth and exhausr port, and control circuit is connected with inflator by interface; Pressure inductor compares with the reference voltage of setting, with the work of control inflator by the air pressure signal of testing product in control circuit.
