Fig. 2 is timer assembly 2 oblique drawings of gas timing valve of the present invention.
With reference to Fig. 2, can find out, timer assembly 2 comprises following components: timer component body 21, the timer actuation gear 22 consisting of a pair of ratchet, resilient member 23, packing ring 24 and gear shaft 25.
Above-mentioned timer component body 21 forms by being positioned at a plurality of gears of inner side and the clockwork spring of actuation gear, when be arranged in after the gear shaft 25 interpolation packing rings 24 and resilient member 23 of gear-linked of above-mentioned timer component body 21 inner sides, will with 22 combinations of timer actuation gear.What adopt due to above-mentioned timer component body 21 is a kind of known technology, therefore, is just no longer elaborated here.
Above-mentioned timer actuation gear 22 consists of a pair of ratchet, specifically, consists of exactly upside timer actuation gear 22a and downside timer actuation gear 22b.
The surface of contact of above-mentioned a pair of timer actuation gear 22 is formed by ratchet respectively, and it can be along a side direction transmission of drive force.
In this case, above-mentioned upside timer actuation gear 22a is with a plurality of gear sawtooth, thus with intermittent gear 32 interlocks of driven unit 3, downside timer actuation gear 22b supports above-mentioned upside timer actuation gear 22a.Above-mentioned downside timer actuation gear 22b and gear shaft 25 are in conjunction with rotating.In this case, for above-mentioned downside timer actuation gear 22b, because the protrusion groove 221b corresponding to being formed on the projection 251 of gear shaft 25 1 sides is positioned at inner peripheral surface, so it can rotate together with gear shaft 25.
Above-mentioned protrusion groove 221b forms in long way along the inner peripheral surface longitudinal side direction of downside timer actuation gear 22b, and downside timer actuation gear 22b can move up and down along longitudinal side direction easily.This is mainly because even if downside timer actuation gear 22b is along moving up and down, also must rotate together with gear shaft 25.
The ratchet that is positioned at above-mentioned downside timer actuation gear 22b upper end portion is corresponding with the ratchet that is positioned at upside timer actuation gear 22a underpart.
As mentioned above, by ratchet, making upside timer actuation gear 22a and downside timer actuation gear 22b interlock is to use when in the process of user's operation timer, pressure is shortened working hours.
Specifically, the surface of contact of above-mentioned downside timer actuation gear 22b and upside timer actuation gear 22a is formed by ratchet, and when upside timer actuation gear 22a counter-rotating, its rotation can not be subject to the interference of downside timer actuation gear 22b.Here, so-called counter-rotating refers to, is positioned at the direction that the clockwork spring (not shown) of timer component body 21 inside loosens.As mentioned above, upside timer actuation gear 22a must counter-rotating in the situation that not interfered by downside timer actuation gear 22b reason be, for the timer component body 21 with downside timer actuation gear 22b interlock, while loosening clockwork spring if force counter-rotating, just easily cause breakage, therefore, must in the situation that not interfered by timer component body 21, make upside timer actuation gear 22a counter-rotating.
This is because timer assembly 2 must be brought into play the effect that the rotation time of the intermittent gear 32 of driven unit 3 is controlled.Specifically, when intermittent gear 32, by being positioned at when the clockwork spring 34 of driven unit 3 inner sides drives, driving force is controlled, timer assembly 2 just performance prevents the break effect that the intermittent gear 32 of driven unit 3 freely rotates.
Owing to can freely rotating with the intermittent gear 32 that is positioned at clockwork spring 34 interlocks of driven unit 3 inner sides, therefore, by timer assembly 2, just can prevent that intermittent gear 32 from freely rotating within the regular hour.
So, the upside timer actuation gear 22a of the timer assembly 2 linking by the intermittent gear 32 with above-mentioned driven unit 3 just can prevent that intermittent gear 32 from freely rotating, if user is rotary regulating lever 35 for mandatory shortening rotation time, by the ratchet with downside timer actuation gear 22b surface of contact, just can in the situation that not interfered by downside timer actuation gear 22b, carry out counter-rotating.
In the normal counter-rotating of the above-mentioned upside timer driver 22a elastic force of clockwork spring (rely on) time, can be controlled the intermittent gear 32 of driven unit 3, due to be resilient member 23 by supporting downside timer actuation gear 22b with certain pressure contact in upside timer actuation gear 22a, therefore, can only prevent by intermittent gear 32 counter-rotating of upside timer actuation gear 22a.
Fig. 3 is that the driven unit 3 of gas timing valve of the present invention launches oblique drawing.
With reference to Fig. 3, can find out, above-mentioned driven unit 3 comprises: driven unit outer cover 31, intermittent gear 32, gear stick 33, clockwork spring 34 and adjustable lever 35.User can rotary regulating lever 35 in order to set the driving time of gas intervening vaive (not shown), and can driving timing device assembly 2 and bonnet assembly 4.
In this case, above-mentioned intermittent gear 32 refers to, the gear only forming in the situation of some existence in the gear teeth of gear.This is to prevent that it is rotated further after rotating when a part of gear for characteristic of the present invention.Specifically, with regard to common gas intervening vaive, its turning radius is 90 °, and this is for controlling its rotation more than above-mentioned scope on the one hand, on the other hand for preventing from being subject to the interference more than control range of timer assembly 2.
Above-mentioned intermittent gear 32 is positioned at driven unit outer cover 31 inner sides, by gear stick 33 combinations, also can rotate.In this case, due to above-mentioned intermittent gear 32 and clockwork spring 34 combinations, therefore, can rotary regulating lever 35.
Specifically, driven unit outer cover 31 consists of upside driven unit outer cover 31a and downside driven unit outer cover 31b, is inserted with intermittent gear 32 between above-mentioned upside and downside driven unit outer cover.
Above-mentioned adjustable lever 34 is combined with a side of gear stick 33, on the downside end of said gear rod 33 in conjunction with for driving the break of the break 43 possessing on bonnet assembly 4 to drive cap 48, if rotating, intermittent gear 32 surpasses certain angle, will make break drive cap 48 to rotate, thereby drive break 43.
Fig. 4 is that the bonnet assembly 4 of gas timing valve of the present invention launches oblique drawing.
With reference to Fig. 4, can find out, above-mentioned bonnet assembly 4 consists of following components: bonnet component body 41, be positioned at the intermediate bonnet 42 of being combined with gas intervening vaive above-mentioned bonnet component body 41 inner sides, be positioned at that above-mentioned bonnet component body 41 inner sides are controlled the break 43 of the action of intermediate bonnet 42, made the axle 49 of above-mentioned intermediate bonnet 42 and 41 combinations of bonnet component body, the clockwork spring 46 that above-mentioned intermediate bonnet 42 is rotated.
In addition, inner side in intermediate bonnet 42 is also provided with intervening vaive fixing spring 47, when making gas intervening vaive and intermediate bonnet 42 combinations and it is controlled, can cushion the impact putting on gas intervening vaive, gas intervening vaive is supported, keep certain elasticity.
In addition, be also provided with the break that above-mentioned break 43 is driven and drive cap 48.
Above-mentioned bonnet component body 41 utilizes axle 49 in inner side, to be provided with intermediate bonnet 42, for guaranteeing that the intermittent gear 421 of above-mentioned intermediate bonnet 42 can give prominence to, in its side one side, is provided with intermittent gear aspis 413.Meanwhile, be also provided with the ratchet joining hole 414 with above-mentioned intermittent gear aspis 413 adjacency.In addition, in side face one side, be provided with the gear stick patchhole 411 that gear stick 33 inserts, be provided with break patchhole 412 with said gear rod patchhole 411 adjacency.
Be positioned at above-mentioned bonnet component body 41 inner sides intermediate bonnet 42 underparts by axle 49 combinations be provided with can interpolation gas intervening vaive space, in addition, be also provided with the brake locks fastener device 422 that is adjacent to the intermittent gear 421 that is positioned at side face one side.In this case, above-mentioned brake locks fastener device 422 is by contacting with break 43, thereby can control the rotation of intermediate bonnet 42.
Specifically, break 43 contacts with brake locks fastener device 422.In this case, above-mentioned break 43 is contacted with brake locks fastener device 422 by resilient member 44, if rotate intermediate bonnet 42, brake locks fastener device 422 also can rotate thereupon.As mentioned above, if turning stopper locker 422, the break 43 contacting is with it stuck on the end of brake locks fastener device 422, thereby controls the rotation of intermediate bonnet 42.
The control of this break 43 can drive cap 48 to implement by break.When user's rotary regulating lever 35, the break of being combined with one side drives cap 48 also to rotate thereupon, thereby drives break 43.Specifically, on the end of break driving cap 48, be provided with projection, when above-mentioned projection is rotated, can drive break 43.Being shaped as of above-mentioned projection only make cylindrical shape break drive a part in cap 48 ends to extend and form circular-arc, when break drives cap 48 to rotate, break 43 is contacted with above-mentioned protruding part, resilient member 44 that so just can compression brake 43, and make break drive cap 48 to rotate, if break 43 departs from protruding part, just can under the elastic force effect of resilient member 44, recover.Utilize this principle just can utilize the rotation of 43 pairs of intermediate bonnet 42 of break to control.
For above-mentioned a series of action, if user is rotary regulating lever 35 in order to set timer, will make the intermittent gear 32 of driven unit 3 rotate, the ratchet assembly 5 of interlock also can rotate thereupon with it, thereby just can make the intermediate bonnet 42 linking with it rotate.
Fig. 5 is that the ratchet assembly 5 of gas timing valve of the present invention launches oblique drawing.
With reference to Fig. 5, can find out, above-mentioned ratchet assembly 5 consists of following components: upper side gear 51, downside gear 52, spring 53, combined axis 54.
For above-mentioned ratchet assembly 5, ratchet joining hole 414 combinations of combined axis 54 and bonnet component body 41, downside gear 52 links with the intermittent gear 421 of intermediate bonnet 42.
Above-mentioned upper side gear 51 links with the intermittent gear 32 of driven unit 3, and along with the driving of intermittent gear 32, downside gear 52 is also driven, thereby just can drive the intermediate bonnet 42 linking with downside gear 52.
Here, above-mentioned upper side gear 51 passes through combined axis 54 combinations with downside gear 52, upside and spring 53 combinations, thus side gear 51 and downside gear 52 are closely linked.Because above-mentioned upper side gear 51 is formed by ratchet respectively with the surface of contact of downside gear 52, therefore, when upper side gear 51 counter-rotating, just can prevent the interference of downside gear 52.
This be mainly because, when if user sets the driving time of gas intervening vaive by the intermittent gear 32 of the driven unit 3 with upper side gear 51 interlocks, just must make the clockwork spring 46 of bonnet assembly 4 tighten, therefore, just must together drive with upper side gear 51 with the downside gear 52 of above-mentioned upper side gear 51 interlocks.When the timer assembly 2 of controlling due to the rotation time of the intermittent gear 32 by driven unit 3 makes intermittent gear 32 counter-rotatings (loosening the direction of clockwork spring) of driven unit 3, upper side gear 51 just links with intermittent gear 32, therefore, must get rid of the interference of downside gear 52.
Based on above reason, when the ratchet counter-rotating of upper side gear 51 by forming on the surface of contact of upper side gear 51 and downside gear 52 respectively, just can be in the situation that be subject to interfere and rotate with the downside gear 52 of bonnet assembly 4 interlocks.
In addition, upper side gear 51 and downside gear 52 remain contact condition by being positioned at the spring 53 of the upside of upper side gear 51.
Fig. 6 is the fragmentary cross-sectional view that shows gas timing valve working state of the present invention.
With reference to Fig. 6, can find out, for gas timing valve of the present invention, if when user's rotary regulating lever 35 is set driving time, the intermittent gear 32 together rotating with adjustable lever 35 also can rotate thereupon.In this case, just can rotating ratchet assembly 5 by being arranged on gear on intermittent gear 32, make to rotate with the intermediate bonnet 42 of the bonnet assembly 4 of above-mentioned ratchet assembly 5 interlocks, and the clockwork spring 46 that is incorporated into intermediate bonnet 42 is tightened, thereby keep elastic force.
As mentioned above, when intermittent gear 32 rotates, the break combining with gear stick 33 ends of intermittent gear 32 combinations drives cap 48 also to rotate thereupon, and make pressurizeing and be contacted with above-mentioned break and drive the protruding part of the break 43 of cap 48 to depart from from break 43, and move with brake locks fastener device 422, finally latch on the end of above-mentioned brake locks fastener device 422.As mentioned above, on brake locks fastener device 422, snap close break 43, thereby can control intermediate bonnet 42, does not rotate.
As mentioned above, by forming the part of the gear of intermittent gear 32, ratchet assembly 5 is rotated, make after actuating valve cap assembly 4, the part of formative gear just departs from ratchet assembly 5, and the upside timer actuation gear 22a of the timer actuation gear 22 on driving timing device assembly 2.In this case, by above-mentioned upside timer actuation gear 22a, just rotate with the downside timer actuation gear 22b of being combined with ratchet, and a plurality of gears and the clockwork spring that are positioned at timer assembly 2 inner sides are rotated, thus setting control time.
In this case, tighten with the clockwork spring 34 of above-mentioned adjustable lever 32 combinations, thereby hold elastic force.
As mentioned above, if user's rotary regulating lever 35 setting control times, the clockwork spring that is arranged on timer assembly 2 inner sides just loosens the regular hour, makes to be arranged on timer actuation gear 22 counter-rotatings on timer assembly 2.
As mentioned above, if 22 counter-rotating of timer actuation gear, the also counter-rotating of intermittent gear 32 that links with it and contact.In this case, under the elastic force effect of clockwork spring 34 that is positioned at above-mentioned intermittent gear 32 inner sides, intermittent gear 32 counter-rotatings, the also counter-rotating of adjustable lever 35 of interlock with it, the control time that just can set according to user is carried out counter-rotating.In this case, for the upper side gear 51 of the ratchet assembly 5 contacting with above-mentioned intermittent gear 32, the surface of contact contacting with downside gear 52 is formed by ratchet, therefore can freely counter-rotating in the situation that not interfered by downside gear 52.
