Detailed description of the invention
Below in conjunction with drawings and Examples, invention is described in detail.
As shown in Figure 1 and Figure 2, in this embodiment, the slow pressure device of air check comprises check system 1, slow pressing system 2 and adapting system 3, and the mode that each system of this device takes clamping to be successively communicated with forms current path.Check system 1 comprises that fixed card is connected on the connection tube 11 and the air check valve 12 that is communicated in this connection tube right-hand member on air pump 7; The right-hand member of air check valve is communicated with the slow left end of pressing storehouse 21 of cumulative in slow pressing system 2, and the slow right-hand member of pressing storehouse of this cumulative is communicated with the left end on T-shaped tee T 4 transverse arms, and the right-hand member of its transverse arm is communicated with adapting system 3.
As shown in Figure 3, air check valve 12 comprises the cylindrical shell of a hollow, and its two ends are respectively air inlet 121 and gas outlet 122, and the bore of gas outlet is greater than inlet end, Non-Return steel ball 123 is arranged near in the cavity of air inlet, and a return spring 124 is resisted against on Non-Return steel ball.In conjunction with Fig. 2, Fig. 3, the housing excircle of air check valve is provided with the cylindric attachment cap 126 of a step 125, and is plugged on the sidewall that this step forms, and cumulative is slow presses the connection tube in storehouse 21 to insert in attachment cap and is resisted against the other end of return spring.
As shown in Figure 2, the slow pressure of cumulative storehouse 21 is an ellipsoid shape air bag, and its outer wall is provided with reflective cumulative coating 211, and this coating can reflect away extraneous pollution light and ensure air quality in storehouse; Be provided with a transparent groove at the slow top of pressing left side, storehouse link of cumulative, in groove, be provided with a LED ultraviolet pipe 212.In working order, this ultraviolet pipe, to irradiating in air bag, increases illumination energy by the reflective cumulative coating refraction of gasbag ektexine, thereby strengthens air in storehouse to carry out ultraviolet-sterilization sterilization; When after gas access to plant, the slow space of pressing storehouse of cumulative can be good at holding gentle pressure of bringing from source of the gas gas, and makes the next working link of the flow direction of steady air current, has ensured the controllability of gas, safety simultaneously.
As can be seen from Figure 2, the perpendicular arm port of T-shaped tee T 4 is provided with an air pressure induction apparatus 6, in working order, this air pressure induction apparatus can be according to the atmospheric pressure state in path by data feedback to control device, carry out steady air flow thereby control the work of air pump, ensured the reliable and stable of air-flow in whole path.
As shown in Figure 4, adapting system 3 comprises the sheath body 31 of a hollow, and its bottom bends inwards and forms ring limit 311, one handle 34 is fixed by bolt 33 in upper end at this sheath body, and this handle below is provided with air-flow converting interface 35, in the time pressing down handle, air-flow converting interface and atmospheric exposure, on the contrary open; The left vertical of this converting interface is provided with an air inlet pipe 36, it passes sheath body outer wall and stretches in T-shaped tee T transverse arm and forms path, between this converting interface and the ring limit of sheath body bottom, be also provided with a seal washer 37, on the sidewall of seal washer, be also provided with a LED ultraviolet pipe 32, it is through seal washer and stretch into its intracavity, and its effect is that intrasystem air-flow is carried out to ultraviolet-sterilization sterilization.In working order, the air-flow with certain pressure can dock and export with one-time infusion tube 38 in adapting system, and the seal approach of adapting system inside does not leak gas, has ensured the air-tightness of device.
With reference to Fig. 1, for pre-air-prevention and other foreign body are by seal 39 accesss to plant of switching device shroud base, be furnished with a soft rubber stopper 5 at sealing mouth place, in the time that equipment quits work, this soft rubber stopper is clogged to seal.
In the present embodiment, the device communicating with gas passage in this device all adopts medical transparent silica gel material to make.
When work, air pump 7 is sent into air check valve 12 by gas by connection tube 11, the elastic force that the air-flow with certain pressure overcomes return spring 124 is pushed Non-Return steel ball 123 open and is entered the slow storehouse 2 of pressing of cumulative, then the gentle pressure induction apparatus 6 of the T-shaped tee T 4 of airflow passes, then air-flow enters in airtight adapting system 3 through T-shaped tee T, enters one-time infusion tube 38 through air-flow converting interface 35; In said process, the ultraviolet pipe on slow pressing system and adapting system distributes ultraviolet the air-flow in it is carried out to sterilizing; While quitting work, Non-Return steel ball 123 is automatically blocked air check valve 12 under the reset force of return spring 124, uses soft rubber stopper to seal seal 39 simultaneously.
The present invention has adopted air check system, slow pressing system and adapting system, has not only ensured controllability and the safety of gas, has ensured the air-tightness of device; Also avoided the gas and the liquid medicine contamination that cause because of irradiate light and gas backstreaming, this installs to increase air containment simultaneously, air is produced to buffering delay effect, thereby make LED ultraviolet pipe carry out efficient sterilizing to air in air bag.
