Specific embodiment
In order to make those skilled in the art better understand the utility model, below in conjunction with the utility model reality
The attached drawing in example is applied, the technical solutions in the embodiments of the present invention are clearly and completely described.
As shown in Figure 1-3, buckle-type flexible encapsulated liquid flowing tube, liquid flowing tube includes glass tube 1, Rubber end 2, pressing piece 3, outer
Casing 4, inner sleeve 5 and sealing element 6；The through-hole being pierced by for glass tube 1, the top of glass tube 1 and rubber are provided on inner sleeve 5
Rubber head 2 is fixedly connected；The pressing piece 3 of pressable Rubber end 2 is connected on Rubber end 2, being additionally provided on liquid flowing tube can prompt
The suggestion device of pressing piece 3 according to pressing depth.Suggestion device includes the elastic plectrum 7 being set on 4 inner wall of outer tube and is set to
For groove 8 and the groove 8 on 3 outer wall of pressing piece close to the bottom end of pressing piece 3, elastic plectrum 7 can match sending with groove 8
Prompt tone.Specifically take liquid process are as follows: give 3 one downward pressure of pressing piece, pressing piece 3 will drive Rubber end 2 and bullet occurs
Property deformation so that glass tube 1 and the combined air pressure inside of Rubber end 2 change, and takes the number of liquid to be decided by rubber
First 2 occur elastically-deformable size, and the deformation that Rubber end 2 is extruded is big, takes liquid more；The deformation that Rubber end 2 is extruded is small, takes liquid
It is few.The liquid flowing tube of the utility model is chiefly used in liquid make-up and takes liquid, and liquid make-up takes the metering basic demand of liquid every time
It is identical, and current liquid make-up liquid flowing tube on the market not can control and liquid taken to measure, and often will cause and liquid is taken excessively to drip back again
In cosmetic bottle, cosmetics are easily caused to be secondary polluted in this way, therefore, the utility model presses process in pressing piece 3
In can issue prompt tone, prompt real user to take liquid enough.Specifically；Rubber end 2 occurs elastically-deformable size and takes
The path length that pressing piece 3 certainly presses down on；When pressing piece 3 moves downward, the bottom end of pressing piece 3 can be from elastic plectrum 7
Side move to the other side；So elastic plectrum 7 can match sending prompt tone, that is, elastic plectrum 7 with groove 8
The elastic deformation of generation and the prompt tone issued prompt user's sampling enough, at this point, elastic plectrum 7 be located just at it is recessed
In slot 8, elastic plectrum 7 just plays the role of a baffle, so that pressing piece 3 does not continue to move downward, takes liquid at this time just
Terminate, removes the pressure for giving pressing piece 3, Rubber end 2 is capable of resetting, that is, Rubber end 2 gives 3 one outside works of pressing piece
Firmly so that pressing piece 3 also resets.
In order to increase the service life of the suggestion device, along center symmetric setting, there are two elastic dialings on 4 inner wall of outer tube
Piece 7；There are two grooves 8 along center symmetric setting for 3 outer wall of pressing piece；Namely when an elastic plectrum 7 is broken, another is elastic
Plectrum 7 can continue to issue prompt tone, the probability of the damage of the suggestion device of reduction.Elastic plectrum 7 is right angled triangle, elasticity
The first edge 71 of 7 upside of plectrum is vertical with the inner wall of outer tube 4;The tilt angle of the second edge 72 of 7 downside of elastic plectrum
It is identical as the tilt angle of lower inclined plane 81 of groove 8.Elastic plectrum 7 is right angled triangle, main in order to increase elastic plectrum 7
Firmness it is not easy to break when elastic deformation repeatedly occurring up and down so that elastic plectrum 7 is under external force or so；And elastic plectrum
The tilt angle of the second edge 72 of 7 downsides is identical as the tilt angle of lower inclined plane 81 of groove 8, then is in order to which pressing piece 3 is multiple
Required active force is smaller when position, that is, Rubber end 2 resets generated upward active force and is sufficient to make pressing piece 3 also multiple
Position.
Inner sleeve 5 is connect with the inner thread of sealing element 6, and the outer wall of sealing element 6 and the inner wall of outer tube 4 are clamped；Pressing
It is provided with press section 32 on part 3, offsets at the top of press section 32 and Rubber end 2, the top of outer tube 4 is provided with the first bending part
41, the second bending part 31 is provided on pressing piece 3, and the first bending part 41 can be matched with the second bending part 31 so that pressing piece
3 move up and down along the vertical direction of outer tube 4；Outer tube 4 and pressing piece 3 are usually plastics or metal material, and first is curved
Folding part 41 can be integrally formed with the second bending part 31, and it is convenient to make, and the first bending part 41 can be with the second bending part
31 design can also guarantee well pressing piece 3 along outer tube 4 vertical direction move up and down, and guarantee pressing piece 3 along
The vertical direction of outer tube 4, which moves up and down, not only can be improved the service life of elastic plectrum 7, moreover it is possible to further guarantee rubber
First 2 occur elastically-deformable size, guarantee accurate measurement.In order to which Rubber end 2 and pressing piece 3 are not easy to be displaced, the top of Rubber end 5
Triangular shaped projections 52 are provided with, press section 32 is located at around protrusion 52, this ensures that the generated pressure of press section 32
Power always situated in press section 32 around, thus be further ensured that take liquid measure accuracy.
Obviously, described embodiment is only a part of the embodiment of the utility model, instead of all the embodiments.
Based on the embodiments of the present invention, obtained by those of ordinary skill in the art without making creative efforts
The range of the utility model protection all should belong in every other embodiment.
