Description

The ventilating control valve

Technical field

The utility model refers to a kind of controller of may command gas inflated amount especially about a kind of ventilating control valve.

Background technique

Bad need crouching for a long time in row lies at the patient of sick bed, for fear of the elaborate sore that produces because of couching for a long time, therefore the patient can select mostly to couch and arrange the air mattress that forms by a plurality of air bags, this air mattress is to utilize air pump to be inflated, and utilize ventilating control valve control aeration quantity, make this air mattress can not produce elaborate sore because of contacting for a long time with certain some of patient's body.

Please refer to the cylinder 92 that ventilating control valve shown in Figure 6, traditional comprises that a motor 90 and with rotating shaft 91 is located on the motor 90 forms; Wherein, this cylinder 92 comprises a cylinder body 93 and a cylinder cap 94, this cylinder body 93 forms a discharge chamber 931 and forms a suction chamber 932 respectively in discharge chamber 931 relative both sides in centre, and this cylinder body 93 forms two steam outlet pipes 933 and two suction tude 934 respectively on the side diametric plane of front and back, and this steam outlet pipe 933 is connected with discharge chamber 931 and two suction chambers 932 respectively with suction tude 934, and this cylinder cap 94 is hubbed in the rotating shaft 91 of motor 90, and has a plenum chamber 941 in this cylinder cap 94, for the usefulness of the control gaseous flow direction.

Please refer to Fig. 7 and shown in Figure 8, when the plenum chamber 941 of this cylinder cap 94 is switched to suction chamber 932 with cylinder body 93 when joining with discharge chamber 931, this suction chamber 932 can be interconnected with plenum chamber 941 with discharge chamber 931, makes gas only be flowed out or be flowed out by two steam outlet pipes 933 respectively by one of them steam outlet pipe 933 of cylinder body 93; By this, to reach the purpose of the control gaseous flow and the flow direction.

But this mode, 93 need of this cylinder cap 94 and cylinder body are very tight, released by

cylinder cap

94 and 93 of cylinder bodies to avoid gas; Therefore, this cylinder cap 94 must be quite accurate when making with cylinder body 93, causes the fabricating cost of this cylinder 92 high and be unfavorable for reducing its cost of production.

The model utility content

Therefore, the utility model main purpose is to provide a kind of ventilating control valve, and its part does not need can finish through the making of precision, can effectively reduce the fabricating cost of this product, promotes the competitive ability of dealer on market and be beneficial to.

The technological means of taking in order to achieve the above object is to make aforementioned ventilating control valve, comprising:

One valve seat, it has a base plate, forms a perforation on this base plate, and this valve seat plate after both sides have a header board and respectively before and after the base plate, and this header board forms a relative trepanning respectively with the two ends of back plate; One motor is located at the bottom of valve seat, and this motor top is provided with a rotating shaft, and is passed by the perforation of valve seat base plate; One pivot member is fixedly arranged in the rotating shaft of motor, and this pivot member one side is pivoted with the casting die of pulling; And two inflated hoses, be located at the trepanning of above-mentioned valve seat respectively and be adjacent to the both sides of pivot member.

When this motor driven pivot member and when this pivot member is rotated, this casting die of pulling also can begin rotation with pivot member, makes this casting die compressing inflated hose bore of pulling, to reduce its flow, by this with the flow and the flow direction of control gaseous.

Because each part of the utility model ventilating control valve need not have high precision when making, so the more traditional ventilating control valve of its fabricating cost is cheap, so can effectively promote the competitive ability of this product on market.

Embodiment

Please refer to illustrated in figures 1 and 2ly, the utility model is a kind of ventilating control valve, and it comprises a valve seat 10, a motor 20, a sensitive switch 30, a pivot member 40, a spring 50 and two inflated hoses 60.

This valve seat 10 comprises that a base plate 11, a upper plate 12, a header board 13, a back plate 14 and biside plate 15 form; Wherein, this valve seat 10 forms a perforation 111 on base plate 11, and this valve seat 10 forms a relative trepanning 16 respectively in the two ends of header board 13 and back plate 14, and this valve seat 10 has a recess 141 in back plate 14 central authorities contiguous root edge place, and upper plate 12 centre of valve seat 10 have a positioning hole 121 again.

This motor 20 is located at the bottom of valve seat 10, and these motor 20 tops have a rotating shaft 21 that is passed by the perforation 111 of valve seat 10 base plates 11, this rotating shaft 21 forms a fixed hole 22 in the diametric plane place of adjacent top end, can wear a driveshaft 23 that is complementary with fixed hole 22 on this fixed hole 22; This sensitive switch 30 is located at recess 141 places of valve seat 10 back plates 14 and is connected with a control gear, and this sensitive switch 30 is provided with a reed 31, with as with the usefulness of pivot member 40 shake-up timing.

This pivot member 40 is cylindric and is fixedly arranged in the rotating shaft 21 of motor 20, and these pivot member 40 tops have a flange 41 that is complementary with upper plate 12 positioning holes 121, be hubbed at the usefulness of valve seat 10 for this motor 20, this pivot member 40 radially forms a caulking groove 42 that is complementary with driveshaft 23 in place, its axle center again, usefulness with and pivot this pivot member 40 moving as these driveshaft 23 pivots, this pivot member 40 radially extends two pivot arms 43 respectively on the diametric plane at contiguous two ends up and down again, 43 on two pivot arms are pivoted and one are the casting die 44 of pulling cylindraceous, in order to the usefulness of extruding inflated hose 60 as the control gaseous flow; Moreover, these both sides, pivot member 40 lower end in plate 14 recesses 141 corresponding positions, back on extend a touch-control arm 45 towards substantially horizontal respectively, one end of this touch-control arm 45 extends to form a touch-control piece 46 downwards, this touch-control piece 46 can touch mutually with the reed 31 of sensitive switch 30 when pivot member 40 rotations, to cooperate this sensitive switch 30 together as the usefulness of fast, the slow frequency of the inflation of measuring the ventilating control valve, these pivot member 40 bottoms are radially to form an alcove 47 again.
