Abstract
The utility model discloses a continuous suction-type ear washing bulb which comprises an air bag with a sleeve at the lower end, wherein an air cock is arranged under the air bag, and an air inlet is formed on the air cock in a penetrating way. The continuous suction-type ear washing bulb further comprises a one-way air renewal device which is formed integrally with the air cock and is provided with a breathing hole, and the air bag is in sleeve joint with the one-way air renewal device through the sleeve and is communicated with the air cock. The continuous suction-type ear washing bulb can ensure that the suction process is continuous and stable when liquid is sucked, overcomes the defect that for a traditional ear washing bulb, misoperation is caused in the cumbersome air renewal process because of the limited capacity of the air bag, improves the operation accuracy in an experiment, and improves the experimental efficiency greatly. By adoption of the split structure of the two parts, aged parts are easy to replace, and experimental expenditure is saved.
Description
Technical field
The utility model relates to a kind of new type of continuous assimilating type ear washing bulb, is particularly useful for the association areas such as chemistry, physics and carries out experimental teaching and scientific research are arranged.
Background technology
In the correlation tests such as chemistry, physics, often utilize at present ear washing bulb to cooperate pipette quantitatively to draw the liquid of certain volume, in actual mechanical process because easy aging damaged etc. the defective of ear washing bulb bag volume finite sum, liquid that usually can not the enough volumes of disposable absorption very easily causes the liquid backflow that has sucked pipette in original solution original solution to be polluted in the process of ear washing bulb ventilation; Perhaps the liquid drawn of ear washing bulb misoperation is inhaled into the situations such as pollution that the ear washing bulb air bag directly causes the solution of being drawn, and the accuracy of experimental result is caused great impact, makes Scientific Inquiry be difficult to reach the effect of anticipation.
Summary of the invention
For the problem that above-mentioned prior art exists, the utility model provides a kind of continuous assimilating type ear washing bulb.
To achieve these goals, the technical solution adopted in the utility model is: a kind of continuous assimilating type ear washing bulb, comprise the sleeved air bag of lower end band, be provided with valve under the air bag, be equipped with air admission hole on the valve, also comprise integrated with valve and with the unidirectional air interchanger of passage, air bag is communicated with unidirectional air interchanger socket and with valve by sleeve.
As preferably, be provided with the valve fixed axis in the unidirectional air interchanger, its top is provided with the unidirectional ventilation valve with valve fixed axis coupling.
As preferably, be provided with choke ball between unidirectional air interchanger and the valve.
As preferably, choke ball and air-vent shape size are complementary, and the position is corresponding.
Compared with prior art, the utility model has the advantage of: the continuous and stable that can guarantee suction process when carrying out the imbitition operation carries out, overcome the operate miss that traditional ear washing bulb causes in loaded down with trivial details scavenging period because of the bag volume restriction, improve the accuracy of experimental implementation, significantly improve conventional efficient, two-part split-type structural is easy to aging part is changed, and saves experiment fees.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A face cutaway view of Fig. 1;
Fig. 3 is the top view of unidirectional air interchanger of the present utility model.
Among the figure: 11, air bag; 12, sleeve; 2, unidirectional air interchanger; 3, valve; 4, unidirectional ventilation valve; 5, valve fixed axis; 6, air-vent; 7, choke ball; 8, air admission hole.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As a kind of embodiment of the present utility model, consult Fig. 1, Fig. 2 and Fig. 3, the utility model comprises that the lower end is with the air bag 11 of sleeve 12, be provided with valve 3 under the air bag 11, be equipped with air admission hole 8 on the valve 3, also comprise integrated with valve 3 and with the unidirectional air interchanger 2 of passage, air bag 11 is socketed with unidirectional air interchanger 2 by sleeve 12 and is communicated with valve 3.Be provided with valve fixed axis 5 in the unidirectional air interchanger 2, its top is provided with the unidirectional ventilation valve 4 with valve fixed axis 5 couplings.Be provided with choke ball 7 between unidirectional air interchanger 2 and the valve 3.Choke ball 7 is complementary with air-vent 6 shape sizes, and the position is corresponding.
Continue to consult Fig. 2 and Fig. 3, choke ball 7 is fixed on the lower end of air-vent 6 correspondences by rubber band, when gas is pushed by air bag 11, gas is gone out by air-vent 6 choke ball 7 is washed open, after air scavenge, choke ball 7 stops gas to enter air bag 11 by air-vent 6 because the pulling force of rubber band is got back to air-vent 6 exits.
The utility model can guarantee that the continuous and stable of suction process when carrying out the imbitition operation carries out, overcome the operate miss that traditional ear washing bulb causes in loaded down with trivial details scavenging period because of air bag 11 capacity limitation, improve the accuracy of experimental implementation, significantly improve conventional efficient, two-part split-type structural is easy to aging part is changed, and saves experiment fees.
Although be recognized as a most practical and preferred embodiment and described the utility model in conjunction with current, but be to be understood that, the utility model is not limited to the disclosed embodiments, and is intended on the contrary contain multiple modification and equivalent arrangements included in the spirit and scope of the appended claims.
