Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following embodiment is only used for clearly illustrating the present inventionTechnical solution, and not intended to limit the protection scope of the present invention.
As shown in Fig. 1 to 5, a kind of electronic nose sucking device for capableing of linear regulation suction, including first shell 1, second shell10, air pump 13, battery 14, suction nasal tube 3, the dirty cup 7 of storage and linear regulation component；First shell 1 is rotated coaxially with second shell 10Connection, air pump 13 and battery 14 are fixed in second shell 10；Inhale nasal tube 3 include air inlet section 2, adjusting cavity 4 and obstruct intoThe partition 5 of gas section 2 and adjusting cavity 4, air inlet section 2 stretch out in first shell 1, and adjusting cavity 4 is fixedly installed in first shell 1.TheIt is provided with connection ring 6 on one shell 1, stores up dirty cup 7 and is separably attached in connection ring 6 by screw thread, air inlet section 2 is also to extensionStretch that formation length is longer into cup section 8, adjusting cavity 4 further extend outward formation length it is shorter go out cup section 9, into cup section 8 and out cupSection 9 all extends in the dirty cup 7 of storage；Linear regulation component is set in adjusting cavity 4, the air inlet and linear regulation component of air pump 13It is connected, gas outlet is connected with the exhaust outlet in second shell 10；Battery 14 is connected with air pump 13；It is opposite to adjust first shell 1The rotation of second shell 2 can drive airflow section linear change in linear regulation component.
Specifically, linear regulation component includes casing 16, piston 15, adjusting spool 19, nut 28 and fixing pipe 17；Casing16 by integrally connected in a connecting plate and adjusting cavity 4, is provided with the flowing of 18 supplied gas of stomata on connecting plate, casing 16 towards intoClosed at one end, the other end opening of the opposite closed end of gas section 2；Fixing pipe 17 is fixed in casing 16, towards air inlet section 2It is closed at one end, the other end of the opposite closed end is open and stretches out adjusting cavity 4 and connect with the air inlet of air pump 13；Fixing pipe 17On from its closed end to its open extreme direction set gradually piston 15, adjusting spool 19 and nut 28, piston 15 and casing 16 andFixing pipe 17 forms dynamic sealing, and the part in fixing pipe 17 positioned at piston 15 and adjusting spool 19 between, which is additionally provided with, to be connected in itThe part of the through-hole 26 in portion, 26 lower section of through-hole is provided with the external screw thread 22 matched with nut 28.The periphery of nut 28 is arrangedThere are several guide grooves 21, accordingly, 4 inner wall of adjusting cavity is provided with guiding raised line and is matched with this with the formation straight-line guidance of guide groove 21It closes.The outer wall of adjusting spool 19 is provided with several regulating tanks 25, the axis of the area of 25 radial section of regulating tank along adjusting spool 19Become larger to linear or approximately linear from the front to the back.
In use, air pump 13 is opened, gas carries dirt and enters in the dirty cup 7 of storage by air inlet section 2 and into cup section 8, gasBody continues through out cup section 9 and enters in adjusting cavity 4.Air-flow is made to pass through adjusting due to being provided with regulating tank 25 in adjusting spool 19In interlayer between 25 sleeve pipe 16 of slot and fixing pipe 17, fixing pipe 17 is then entered by the through-hole 26 in fixing pipe 17In, it subsequently enters in air pump 13 and is discharged eventually by exhaust outlet.When needing to adjust suction, hand-held second shell 10 is motionless,Another hand rotates first shell 1, at this time since helicitic texture makes nut 28 relatively fixed between nut 28 and fixing pipe 17Pipe 17 moves axially, and drives adjusting spool 19 and 15 synchronizing moving of piston.Adjusting spool 19 is mobile so that regulating tank 25 is in casingArea of section at 16 open ends occurs linearly or close to linear variation, thus change air-flow size, final realization suctionLinear regulation.In 19 moving process of adjusting spool, the also synchronizing moving of piston 15, so that between adjusting spool 19 and piston 15Volume remains constant, therefore in suction adjustment process, will not occur to change suction because volume changes and generate fluctuation shadowIt rings, improves the stability of suction adjustment process.
Preferably, piston 15 is connected by several first dowels 23 with adjusting spool 19, and adjusting spool 19 is logicalSeveral second dowels 24 are crossed to be connected with nut 28.Further, piston 15, the first dowel 23, adjusting spool 19, second28 integrally connected of dowel 24 and nut.
Preferably, be provided in fixing pipe 17 between the part of screw thread 22 and non-threaded part formed can be aboutThe limit shoulder 26 of beam adjusting spool 19.When adjusting spool 19 is moved to the maximum position of suction, it is limited shoulder 26 justIt constrains and can not continue to move to, can not also be continued to rotate between first shell 1 and second shell 10 at this time.
Preferably, rotation connection, slip ring 12 are formed by slip ring 12 between first shell 1 and second shell 10It can be replaced by bearing.
Preferably, the exhaust ports of second shell 10 are additionally provided with dismountable rubber plug 11.When nose sucking device usesAfter, rubber plug 11 can be filled in exhaust outlet to prevent into ash, similarly, the air inlet for inhaling nasal tube 3 can also be located in the same wayReason.
Preferably, the gas outlet of air pump 13 is connected by exhaust pipe 20 with the exhaust outlet of second shell 10.
Preferably, the end for inhaling the air inlet section 2 of nasal tube 3 is pyramidal structure, can extend into narrower nose with thisIn chamber.
Preferably, it stores up dirty cup 7 to be made of clear material, convenient for dirt quantity in observation cup to remind userCleaning in time.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the artFor member, without departing from the technical principles of the invention, several improvement and deformations can also be made, these improvement and deformationsAlso it should be regarded as protection scope of the present invention.
