Conduit 12, the valve rod 521 is inserted into conduit 12, and then makes container 52 relative to valve rod 521 with reality by pressing bottle cover 4
The quantitative ejection of existing liquid, specifically, liquid belongs to the prior art from the quantitative ejection principle in container 52, herein no longer in detail
It states.Nozzle casing 111 is arranged on the nozzle 11.
The dose indicating device includes being arranged on conduit 12 and to record the first digital gear disk of ten digits
9, it is arranged on conduit 12 and simultaneously supports on the first digital gear disk 9 and to record the second digital gear of unit numbers
Disk 8, the spring 7 in the annular housing of the second digital gear disk 8, the counting component 6 being supported on spring 7 and support
Index component 5 and the second digital gear disk 8 of realization on counting component 6 drive the gear set of the first digital gear disk 8
10, while the index component 5 is non-rotatably secured to the lower end of container 52.It is both provided with two on second digital gear disk 8
The number of group 0-9 is provided with set of number on the first digital gear disk 9, and for number since 0, ending number can be according to need
It sets, such as can be 10,20, the number of teeth of the first digital gear disk 9 is the number of number.
It is provided with multiple sliding slots 81 extended up and down on the side wall of the annular housing of the described second digital wheel disc 8.It is described
The structure that component 6 is annular is counted, the protrusion 61 coordinated with sliding slot 81 is provided on the downside of the outer rim for counting component 6, works as institute
Protrusion 61 is stated when entering in sliding slot 81, the counting mechanism 6 can drive the second digital rotation of wheel disc 8 to be counted to realize.
The gear set 10 includes gear shaft 101 and 103 He of gear for being separately positioned on 101 upper and lower ends of gear shaft
The lower end of lower gear 102, the gear shaft 101 is hinged on lower part 1, and upper end is hinged on middle part 2, the gear 103
Corresponding with the second digital gear disk 8, the lower gear 102 is corresponding with the first digital gear disk 9.Specifically, in the second digital tooth
The upper end of wheel disc 8 is provided with two teeth 82 radially extended along it, and two teeth 82 are circumferentially separated by 180 °, the tooth 82
It can be engaged with gear 103.The multiple teeth 91 radially extended along it, institute are provided in the lower end of the first digital gear disk 9
The number for stating tooth 91 is corresponding with the number of number.In this way, when the number on the second digital wheel disc 8 is gone to " 9 " from " 0 ", tooth 82
Gear 103 is driven to rotate an angle, gear 103 drives lower gear 102 to rotate an angle, and then the first digit wheel
Disk 9 rotates an angle, which makes the first digital wheel disc 9 rotate a number, i.e., the second digital wheel disc 8 rotates ten numbers
Word, the first digital wheel disc 9 rotate a number.
The upper end of the counting mechanism 6 is provided with internal tooth 63 upward and the external tooth 62 in 63 outside of internal tooth is arranged,
The lower end of the index component 5 is provided with the sliding tooth 51 of the cooperation of internal tooth 63.Middle part is provided in the middle part 2 with for rope
The sealing plate 21 for the through-hole 25 that primer component 5 passes through is provided on the sealing plate 21 and at the position of through-hole 25 and extends downwardly
The limiting tooth 22 coordinated with external tooth 62, the limiting tooth 22 and external tooth 62 be all made of sawtooth, and in the mounted state, limit
The zigzag fashion of tooth 22 and external tooth 62 along the circumferential direction on the contrary, can realize the limit to external tooth 62 in limiting tooth 22 in this way, and
And due to the shape of sawtooth on the contrary, larger active force can be born in the state that limiting tooth 22 and external tooth 62 engage in turn and
The two will not be made to be disengaged from, can prevent from counting 2 autorotation of component when that need not count and keeping counting inaccurate in this way.
It alternately is provided with limiting slot 23 and limited block 24 on the inner edge of the sealing plate 21, outside the downside of index component 5
Edge is respectively arranged with can be in limiting slot 23 with the convex block 53 and groove 54, the convex block 53 of limiting slot 23 and the cooperation of limited block 24
It moves up and down, limited block 24 can move up and down in groove 54, and mobile distance can at least make limiting tooth 22 and external tooth 62
It can be detached from.Before limiting tooth 22 and external tooth 62 are detached from, the tooth peak of sliding tooth 51 drives there is no being engaged with the tooth paddy of internal tooth 63
The tooth paddy of moving teeth 51 does not also engage with the tooth peak of internal tooth 63, and since spring 7 is resisted against the lower part of counting component 6 simultaneously always
Making counting component 6 always has the trend moved towards index component 5, and such sliding tooth 51 and internal tooth 63 just will produce reversed rotation
The trend turned is so that the tooth peak of the two is engaged with corresponding tooth paddy, but due to the effect of limiting tooth 22 and external tooth 62, counts structure
Part 6 and index component 5 can not rotate.
When user's pressing bottle cover 4, container 52 drives index component 5 to move downward, since middle part 2 can not be downward
Movement, constantly moving downward and when reaching certain distance, count 62 meeting of external tooth on component 6 and center with index component 5
Limiting tooth 22 in portion 2 is detached from, after disengaging, since index component 5 can not rotate, at this point, counting the internal tooth 63 on component 6
It returns and rotates the tooth peak for making sliding tooth 51 and tooth paddy and the tooth peak of corresponding internal tooth 63 and the engagement of tooth paddy, and count component 6
It drives the second digital wheel disc 8 rotate when rotated and then realizes primary count.And work as
When unclamping bottle cover 4, under the action of spring 7, counts component 6 and move upwards, transported downwards due to counting component 6
Be detached from when dynamic the rotation that limiting tooth 22 generates prevent limiting tooth 22 tooth peak and tooth paddy from corresponding external tooth 62 and tooth paddy and tooth
Peak engages, in this way when the external tooth 62 on counting component 6, which is moved upward to, to be engaged with the limiting tooth 22 on middle part 2, due to bullet
The upward active force of spring 7, external tooth 62 by towards thereon tooth peak and tooth paddy on corresponding limiting tooth 22 tooth paddy and tooth peak nibble
The direction of conjunction rotates and then counting component 6 is made to rotate certain distance relative to middle part 2, makes the sliding tooth 51 on index component 5
Tooth peak and tooth paddy be staggered with tooth peak and prepare to press next time with the tooth paddy for counting the corresponding internal tooth 63 on component 6.Tool
Body, the principle that driving counts component rotation is similar to the operation principle that the penholder of automatic ball-pen extends and retracts.
In order to observe the number indicated by the first digital gear disk 9 and the second digital gear disk 8, on lower part 1
It is provided with reading window 13, the number by reading the first digital gear disk 9 and the second digital gear disk 8 that window 13 is shown can
To obtain the dosage of medication.
Basic principles, main features, and advantages of the present invention has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the present invention is not limited to the above embodiments, described in the above embodiment and specification
It is the principles of the present invention, the utility model also has various changes on the premise of not departing from the spirit and scope of the utility model
Change and improve, these changes and improvements are both fallen in the range of claimed invention.The protection model of the requires of the utility model
It encloses and is defined by appended claims and its equivalent.
