The specific embodiment
For above-mentioned purpose, the feature and advantage that make the technical program can more become apparent, the below is described in detail the specific embodiment of the technical program.
Set forth detail in the following description so that fully understand the present invention.But the technical program can be different from alternate manner described here and implements with multiple, and those skilled in the art can be in the situation that do similar popularization without prejudice to the technical program intension.Therefore the technical program is not subjected to the restriction of the following public specific embodiment.
Please refer to Fig. 1 and Fig. 2, Fig. 1 is the side schematic view of semi-automatic folding collection cigarette filter assemblies, and Fig. 2 is the schematic rear view of semi-automatic folding collection cigarette filter assemblies.
As depicted in figs. 1 and 2, exhaust fume collecting hood 1 has outer surface 11, inner surface 12 and medial surface 13 (please refer to Fig. 2).Filter 2 has front 21, the back side 22 and side 23, and the outer surface 11 of filter 2 downsides and exhaust fume collecting hood 1 is flexibly connected.The inner surface 12 of elastic telescopicing rod one end and exhaust fume collecting hood 1 is hinged.In the technical program preferred embodiment, elastic telescopicing rod is air spring bar 3, and air spring bar 3 comprises piston rod 31 and cylinder 32, and preferred, the cylinder 32 place ends of air spring bar 3 and the inner surface 12 of exhaust fume collecting hood 1 are hinged.The inner surface 12 of pole 4 one ends and exhaust fume collecting hood 1 is hinged, is not hinged with the hinged piston rod 31 place ends of the inner surface 12 of exhaust fume collecting hood 1 in the other end and the air spring bar 3.Be not hinged with the hinged end of the inner surface 12 of exhaust fume collecting hood 1 in trace 5 one ends and the pole 4, the perforate 14 (please refer to Fig. 2) that the other end passes on the exhaust fume collecting hood 1 is hinged with the back side 22 of described filter 2.
The below is described specifically the operating mechanism of the semi-automatic folding collection cigarette filter assemblies that the technical program provides.
As depicted in figs. 1 and 2, exhaust fume collecting hood 1 has certain angle of inclination (angle of inclination refers to and the vertical direction angulation), thereby also have certain angle of inclination with filter 2 that exhaust fume collecting hood 1 is flexibly connected, and the angle of inclination of filter 2 is equal to, or greater than the angle of inclination of exhaust fume collecting hood 1.
Because filter 2 has certain deadweight and certain angle of inclination, thereby the active force of 2 pairs of traces 5 of filter is always along the downward pulling force of trace 5, and this pulling force increases along with the increase at the angle of inclination of filter 2.
Because trace 5 is hinged with pole 4, thereby the active force of 5 pairs of poles 4 of trace is always along the downward pulling force of trace 5, and this pulling force increases along with the increase at the angle of inclination of filter 2 equally.
In the technical program, elastic telescopicing rod provides all the time and pushes away stress, and this pushes away stress along elastic telescopic club body place directive effect in pole 4.And pole 4 one ends have been articulated on the inner surface 12 of exhaust fume collecting hood 1, thereby pole 4 can provide reaction force acts in elastic telescopicing rod.
For convenience of description, the angle of definition elastic telescopicing rod and pole 4 is that bullet props up angle, the bullet Zhi Heli that makes a concerted effort to be of the active force between definition elastic telescopicing rod and the pole 4 and reaction force.
When bullet propped up angle and is minimum of a value, whole semi-automatic folding collection cigarette filter assemblies was in closure state.At this moment, play the direction of Zhi Heli for obliquely, then the active force of 4 pairs of traces 5 of pole is the tractive force that makes progress along trace 5, and this tractive force greater than 2 pairs of traces 5 of filter along the downward pulling force of trace 5, thereby whole semi-automatic folding collection cigarette filter assemblies can keep closely closure state.
When bullet propped up the arbitrary value of angle between minimum of a value and 180 °, the direction that plays Zhi Heli was always obliquely, thereby the active force of 4 pairs of traces 5 of pole is always the tractive force that makes progress along trace 5.
Prop up angle at bullet and increase to from minimum of a value 180 ° the process, elastic telescopicing rod constantly shrinks on the one hand, and the stress that pushes away of elastic telescopicing rod constantly increases, and causes active force and reaction force between elastic telescopicing rod and the pole 4 constantly to increase; And bullet props up angle and constantly increases on the other hand.The factor of comprehensive above-mentioned two aspects in this process, plays Zhi Heli and props up the increase of angle along with bullet and reduce, and the tractive force that makes progress along trace 5 of 4 pairs of traces 5 of pole also props up the increase of angle along with bullet and reduces.Meanwhile, in this process, the continuous increase at filter 2 angles of inclination, from the above but constantly increasing along trace 5 downward pulling force of 2 pairs of traces 5 of filter, that is the pulling force of 5 pairs of poles 4 of trace props up the increase of angle along with bullet and increases.
When bullet props up angle and is 180 °, when namely elastic telescopicing rod and pole 4 are in alignment, the active force between them and reaction force opposite sign but equal magnitude, playing Zhi Heli is zero, this moment, they did not have active force to trace 5.
Because elastic telescopicing rod and pole 4 all are to be articulated on the inner surface 12 of exhaust fume collecting hood 1, the hinged place has certain framework (for example boss) makes them all exceed certain altitude than the inner surface 12 of exhaust fume collecting hood 1.Thereby elastic telescopicing rod and pole 4 can pull into dihedral degree (namely above 180 °) under continuing after in alignment.If there is not the effect of other power, after elastic telescopicing rod and pole 4 are in alignment, under the effect of the pulling force under trace 5 is oblique, will be continued pulling downwards, namely bullet prop up angle can be above 180 °.
When bullet props up angle above 180 °, bullet props up resultant direction and is transformed into oblique lower, this moment, the active force of pole 4 pairs of traces 5 changed into along the downward motive force of trace 5, the pulling force one of this motive force and 2 pairs of traces 5 of filter works, so that moving downward to whole semi-automatic folding collection cigarette filter assemblies, opens by filter 2, and so that the hinge end of elastic telescopicing rod and pole 4 be resisted against on the inner surface 12 of described exhaust fume collecting hood 1 to reach poised state, bullet propped up angle and reached maximum this moment, and whole semi-automatic folding collection cigarette filter assemblies can keep stable open mode.
In above-mentioned whole process, when bullet props up angle at certain special angle between minimum of a value and 180 °, the tractive force that makes progress along trace 5 of 4 pairs of traces 5 of pole can just equal 2 pairs of traces 5 of filter along the downward pulling force of trace 5, at this moment, whole semi-automatic folding collection cigarette filter assemblies is in a critical condition, under this critical condition, each dynamic balance, bullet props up angle and is defined as critical angle at this moment.
Under above-mentioned critical condition, only need a little upwards to promote filter 2 a bit of distances, filter 2 can drive trace 5 makes trace 5 promote elastic telescopicing rod and pole 4, meeting is so that bullet props up angle less than critical angle like this, then the tractive force that makes progress along trace 5 of 4 pairs of traces 5 of pole greater than 2 pairs of traces 5 of filter along the downward pulling force of trace 5, whole semi-automatic folding collection cigarette filter assemblies can be withdrawn into closely closure state with filter 2 automatically.
Under above-mentioned critical condition, only need to spur filter 2 a bit of distances a little downwards, filter 2 can drive trace 5 and make trace 5 pulling elastic telescopicing rod and poles 4, meeting is so that bullet props up angle greater than critical angle like this, then the tractive force that makes progress along trace 5 of 4 pairs of traces 5 of pole less than 2 pairs of traces 5 of filter along the downward pulling force of trace 5, whole semi-automatic folding collection cigarette filter assemblies can be opened filter 2 automatically.When being opened to bullet and propping up angle and be 180 °, from the above, playing Zhi Heli is zero, the effect that 4 pairs of traces 5 of elastic telescopicing rod and pole are no longer strong, thereby under the effect of downward pulling force along trace 5 of 2 pairs of traces 5 of filter, 5 pairs of poles of trace 4 produce along the downward pulling force of trace 5, and bullet props up angle can be above 180 °.In case bullet props up angle above 180 °, bullet props up resultant direction and is transformed into oblique lower, this moment, the role transformation of pole 4 pairs of traces 5 was along the downward motive force of trace 5, under the acting in conjunction of downward pulling force along trace 5 of this motive force and 2 pairs of traces 5 of filter, whole semi-automatic folding collection cigarette filter assemblies can continue automatically filter 2 to be opened, until stable open mode.
As seen from the above description, the semi-automatic folding collection cigarette filter assemblies that provides for the technical program, when it is in open mode, in the time of only need to upwards promoting filter 2 to bullet and prop up angle slightly less than critical angle, whole semi-automatic folding collection cigarette filter assemblies will auto-closing, and keeps tight closure; When it was in closure state, when only needing that pulling filter 2 to bullet props up angle slightly greater than critical angle downwards, whole semi-automatic folding collection cigarette filter assemblies will be opened automatically, and kept stable and open.Whole operating process is simple and convenient, and whole semi-automatic folding collection cigarette filter assemblies is durable firm.
By the description of the operating mechanism of the above semi-automatic folding collection cigarette filter assemblies that the technical program is provided as can be known, the semi-automatic folding collection cigarette filter assemblies that the technical program the provides folding that to realize semi-automation.
