Description
Technical field
The utility model relates to edible mushroom culture vessel technical field, is specifically related to a kind of air filtering bottle cap.
Background technology
Edible mushroom refers to that fruit body is very large, gill fungus bacterium (macro fungi) that can be edible, is commonly referred to as mushroom.The known edible mushroom of China has kind more than 350; wherein belong to Basidiomycotina more, common are: mushroom, straw mushroom, mushroom, auricularia auriculajudae, white fungus, hedgehog hydnum, dictyophora phalloidea, Trichotoma matsutake (matsutake), dried mushroom, russule, glossy ganoderma, Chinese caterpillar fungus, truffle, lark and bolete etc.; Minority belongs to Ascomycotina, Qi Zhongyou: hickory chick, saddle fungus, ferfas etc.
Since the eighties initial stage, investment is little, the cycle is short, the project of having got rich of instant effect is able to fast development in China as one for edible fungus culturing, and once once supply falls short of demand for edible fungus, and selling price is high.Mushroom industry is a short, adaptable and fast rural economic development project integrating economic benefit, ecological benefits and social benefit, edible mushroom is again that a class is organic, nutrition, health care pollution-free food.Development mushroom industry meets the needs that people consume growth and agricultural sustainable development, is the effective way that peasant gets rich fast.Some country has also built up the mushroom factory of more than the fresh mushroom kiloton of annual output, there have been developed not only for viewing and admiring but also for the technology 21 century edible mushroom that mushroom and mycelium liquid fermenting and producing food additives are planted by the family of food, the gross yield developing into one of the main protein food of mankind edible fungi of china in 2005 being reached 1,200 ten thousand tons, rank first in the world, according to edible fungi of china commerce Net investigation statistics, the gross yield of edible fungi of china in 2010 reaches 2,000 ten thousand tons, accounts for the world 70%.Along with edible fungi liquid strain is produced and industrial cultivation technique, greatly improve the edible fungi of china level of production.Mushroom industry has become an important industry in Chinese plant husbandry.
In edible fungus industrial cultivation, widely used culture vessel has glass or the plastic containers such as triangular flask, wide-mouth bottle or Cans, is covering or can substantially meet after parcel tissue cultures sealed membrane the requirement of Plant Tissue Breeding.But the lid of these containers generally only has common bottlecap functionality, when not by other equipment, be difficult to reach sterilising, every bacterium seal, the requirement inoculating anti fouling performance and gas interchangeability.
Application number 200720070757.3 utility model discloses a kind of cultivation bottle cap, the filter bed comprising a upper cover and a lower cover and be clipped between upper and lower cover, under cover and be provided with ventilation hole, ventilation breach and blow vent, flowing through the air between ventilation hole, ventilation breach and blow vent through filter pad.Can effectively prevent the bacterial classification in culture vessel contaminated, upper cover can be opened, easily to change filter bed simultaneously.The utility model can reach biological culture sterilising, every bacterium seal, inoculation anti fouling performance and the requirement of gas interchangeability, and structure is simple, unique ventilation design fully can ensure gas permeability, filter bed between upper and lower cover, can effectively stop outside air to the pollution of culture vessel.
Above-mentioned patent is by the filter pad between upper cover and lower cover, and carry out gas exchanges by the ventilation hole of lower cover, ventilation breach and blow vent, ventilation hole, ventilation breach and blow vent are all positioned at the side of filter bed, can not filter bed be made full use of, and the phenomenon of gas leakage can be caused because filter bed is not closely sealed.
Application number: 201220157480.9 1 kinds of fungal culture bottle caps, comprise the outer cap rock and interior cap rock that mutually fasten, the interior cap rock at described outer cap rock and interior cap rock fastening place is circumferentially distributed with some cover buckles, fastened by cover buckle between outer cap rock and interior cap rock and form integrative-structure, an interlayer is formed between outer cap rock and interior cap rock, air filtering layer is set in interlayer, the lower surface of outer cap rock is circumferentially distributed with some ventilating grooves near outer ledge place, the upper surface of interior cap rock is circumferentially distributed with the ventilation groove of some positions that is staggeredly located with ventilating groove near outer ledge place.
Above-mentioned patent carries out air exchange by the ventilating groove of outer cap rock edge and the ventilation groove of interior cap rock edge, and as can be seen from structure, the major part of middle filtering layer role is exactly edge, can not make full use of filter bed.And above-mentioned two patents are all adopt sponge filter bed to use as filter course, change and maintenance cost high.
Summary of the invention
The technical problems to be solved in the utility model is: for above weak point, provides a kind of air filtering bottle cap.
The technical scheme that the utility model adopts is:
A kind of air filtering bottle cap, described Bottle cap structure comprises upper cover part and lower cover part, and wherein, upper cover part and lower cover part snap together, between form filter course, be provided with filter bed in filter course; Upper cover part is provided with blow vent, and forms venting channels together with the space between upper cover part and filter course; Lower cover portion is divided and is provided with scavenge port, and forms scavenge duct together with the space between lower cover part and filter course.
The diameter of described lower cover part is less than the diameter of upper cover part, and described blow vent is arranged at the lower surface of upper cover part, submarginal part.When bottle cap is fastened on culture vessel mouth, due to blow vent down, falling into of grieshoch foreign material etc. can be avoided, keep the clean and unobstructed of venting channels.
A lower cover portion point outer rim circumferential position is provided with a circle enclosing cover limit, by enclosing cover limit, bottle cap is placed on culture vessel mouth.
The inner surface of described upper cover part, is provided with some projections with filter course opposite segments, and when upper cover part and lower cover part snap-fit, the protruding filter bed compressed in filter course, avoids filter bed to move phenomenons such as causing gas leakage.
The structure of described lower cover part comprises outer perimeter section, inner round portion and is positioned at middle ring part, wherein outer perimeter section and inner round portion are positioned at a plane, during use and filter course compress, ring part protrudes from the plane of outer perimeter section and inner round portion, and and between this plane, form a space, the part that ring part is adjacent with inner round portion with outer perimeter section forms the scavenge port of lower cover.This structure can expand the area of filter course filtration fraction, increases the efficiency of air exchange.
Described filter bed is filter paper, because filter paper thickness is very little, therefore greatly can reduce the thickness of filter course, thus reduces the thickness of bottle cap, and uses filter paper, and cost is low, and be convenient to change, operation and maintenance is all very convenient.
The beneficial effects of the utility model are:
The utility model structure is simple, easy to use, good filtration effect, and filter bed cost is low, is convenient to change, and during use, upper cover part and lower cover part is separated, filter paper is put into middle filter course, fasten upper and lower covers, also very convenient during replacing.
