Description
The utility model relates to a kind of gas pressure regulator of improved air bed inflator.
At present, medical institutions often utilize the inflatable substrate of air bed and so on to replace manpower and stand up for the patient, make patient's back unlikely generation skin histology necrosis; The inflator of air bed (Fig. 1) mainly contains pump 1, gas direction control valve 2 and a gas pressure regulator 3, and the footpath is by the exhaust chamber 31 of a three-way pipe 11 difference conveying gas to gas direction control valve 2 and gas pressure regulator 3 when pump 1 conveying gas; Gas direction control valve 2 alternately by two suction tude, 21,22 input air pressure controllers 3, offers air bed 4 with input air pressure again; Improper as pressure control, then can cause air bed too soft or too hard, and influence its effect.
Known gas pressure regulator (Fig. 2) is to be made of exhaust chamber 31, air bag 32 and cover plate 33, cover plate 33 ends hold at relief opening 34, relief opening 34 is connected the outlet pipe 12 of pump, cover plate 33 bottoms have an adjusting knob 35 elasticity to hold cover plate 33, make relief opening 34 sealings, then all air inlets of pump are pressed and are all supplied with air bed through suction chamber 36; Known gas pressure regulator complex structure, the manufacture cost height, and be difficult to reach accurate adjustment standard.
The purpose of this utility model is the gas pressure regulator that a kind of improved air bed inflator will be provided, and it can not only precise pressure control, and easy and simple to handle.
The purpose of this utility model is achieved in that a kind of gas pressure regulator of air bed inflator, make the gas that pumps out by a three-way pipe branch to two bursts of outputs, one imports gas direction control valve, borrowing gas direction control valve that air inlet is divided into two bursts of intermittences exports alternately, directly be communicated with air bed, another air outlet of three-way pipe then is communicated to gas pressure regulator; It is characterized in that gas pressure regulator is made up of continuous piece, joint, taper, spring and knob: wherein, joint is coated in the continuous piece, is a hollow tube, and the top is provided with the suction port of intake grill connection at three-way pipe, the lateral margin control is provided with relief opening, and the bottom periphery is a fixing part; The awl post is located at the below of intake grill in the joint: spring is located at and holds in the joint at the awl post; Knob is arranged in the joint bottom, and gas pressure regulator can a plurality ofly be arranged in parallel.
Owing to adopt such scheme, the utility model pressure control system utilizes suction pressure directly to back down relief opening, needn't must be poured into air bag earlier as known technology, again roof pressure cover plate and exhaust indirectly is therefore comparatively accurate on pressure controlled precision.Reduce members such as air chamber, air bag, cover plate, on making, reduced many assembly programs and shaping die, thereby escapable cost.Owing to be provided with the continuous piece 301 that is coated on outside the joint, supplied gas does not have noise when discharging during exhaust.
Below by accompanying drawing and embodiment the utility model is further described.
Fig. 1 is known air bed inflator structural representation.
Fig. 2 is known air bed inflator gas pressure regulator sectional view.
Fig. 3 is the key plan of the utility model embodiment in inflator.
Fig. 4 is the utility model embodiment's STRUCTURE DECOMPOSITION figure.
Fig. 5, the 6th, the utility model embodiment move schematic representation.
Among the figure: 10 pumps, 20 gas direction control valves, 30 gas pressure regulators, 40 air beds, 101 three-way pipes, 301 continuous pieces, 302 joints, 303 awl posts, 304 springs, 305 knobs, 321 intake grills, 322 relief openings, 323 fixing parts.
Below in conjunction with accompanying drawing 3-5 structure of the present utility model is described in detail:
Referring to Fig. 3; Be the position signal of the utility model embodiment in inflator, the air inlet that pump 10 is carried is pressed by a three-way pipe 101 minutes to two bursts of outputs, wherein one imports gas direction control valve 20, borrowing gas direction control valve 20 that air inlet is divided into two bursts of intermittences exports alternately, directly be communicated with air bed 40, another exhaust outlet of three-way pipe 101 then is connected to gas pressure regulator 30, therefore gas pressure regulator 30 needn't be connected the mutual output tube of importing air bed 30 through gas control valve 20, can make the structure decrease of gas pressure regulator 30 thus.
As shown in Figure 4; Gas pressure regulator 30 includes a continuous piece 301, a joint 302, awl post 303, a spring 304 and a knob 305; Continuous piece 301 is coated on joint 302 peripheries; Joint 302 is a hollow tube, and the top has intake grill 321 to be communicated with in two bursts of air outlets of three-way pipe 101 one, and lateral margin has dug relief opening 322, and the bottom periphery is a fixing part 323; Taper 303 is located in the joint 302, below intake grill 321; Spring 304 is located in the joint 302, holds below awl post 303; Knob 305 is arranged in joint 302 bottoms, and rotatable adjustment spring 304 holds the elastic force of awl post 303.
As shown in Figure 5; When the suction pressure of intake grill 322 is too big, post 303 is bored in i.e. compressing, make spring 304 stressed and compress, then bore post 303 and promptly produce the gap with intake grill 322, air inlet is poured in the joint 302 by intake grill 322, and discharge, to release the pressure by the relief opening 322 of joint 302, when treating that suction pressure weakens, spring 304 promptly holds awl post 303 and seals intake grill 322 again.
The program of present embodiment air bed pilot pressure is: when pump 10 begins to supply the air inlet pressure, promptly by three-way pipe 101 lead respectively gas pressure regulator 30 and gas direction control valve 20, at this moment, owing to gas pressure regulator 30 is held by taper 303 in the joint 302 and spring 304 is closed state, therefore air inlet is pressed and is all offered air bed 40 actions through gas direction control valve 20, when treating that the pressure of air bed 40 is enough, even being communicated with in the air inlet of gas reduced pressure controller 30, the pressure three-way pipe of recalling 101 presses increase, begin venting even press increase gas pressure regulator 30 when air inlet, pressure is reduced, until till the recovery standard, to reach the purpose of pilot pressure.Gas pressure regulator 30 can use in simultaneously a plurality of parallel connections, to increase pressure controlled scope.
