Abstract
The utility model discloses a kind of Novel ear-washing ball with relief valve, it comprises sacculus, connecting portion, suction nozzle, relief valve, Magnet, mesa-shaped housing, annular cover plate, spherical float valve and the strong point；The design of the strong point makes spherical float valve even at still there being space can meet the free flow of gas between least significant end and suction nozzle, when liquid rises to the position of spherical float valve, spherical float valve starts to float and cannot rise with liquid during annular cover plate Guan Bi thus avoid liquid and enter inside ear washing bulb.Avoiding liquid and suck the problem within ear washing bulb, slow down ear washing bulb aging, extend service life, simple in construction, cost of manufacture is low, is worth promoting on a large scale.
Description
[technical field]
This utility model relates to chemical apparatuses technical field, is specifically related to a kind of Novel ear-washing ball with relief valve.
[background technology]
Ear washing bulb, also referred to as rubber pipette bulb, drifting dust ball, foot blower, skin blow son, be a kind of rubber be the instrument instrument of material,
It is mainly used in pipette and quantitatively extracts liquid.In laboratory, ear washing bulb is mainly used in pipet and the quantitative extract of pipette
Body, often occurs liquid to be inhaled into the problem within ear washing bulb during this, this can accelerate, and ear washing bulb is aging, shorten use
In the life-span, pollute the reagent drawn, cause some unexpected injuries, especially strong acid and strong base solvent simultaneously.
[utility model content]
The purpose of this utility model is the defect for prior art and deficiency, it is provided that a kind of novel with relief valve
Ear washing bulb, this ear washing bulb is possible to prevent liquid to suck.
In order to solve the problem existing for background technology, a kind of Novel ear-washing ball with relief valve of the present utility model,
It comprises sacculus, connecting portion, suction nozzle, relief valve, Magnet, mesa-shaped housing, annular cover plate, spherical float valve and the strong point；Sacculus leads to
Crossing connecting portion to be bonded together with suction nozzle, be provided with Magnet bottom sacculus, be provided with relief valve inside suction nozzle, relief valve is by mesa-shaped shell
Body, annular cover plate, spherical float valve and the strong point are constituted, and mesa-shaped housing upper end arranges annular cover plate, and mesa-shaped enclosure interior is arranged can
Freely up and down movable spherical float valve, spherical float valve arranges 4 symmetrical support point strong points respectively, and the design of the strong point makes
Spherical float valve even at still there being space can meet the free flow of gas between least significant end and suction nozzle, liquid rises to
During the position of spherical float valve, spherical float valve liquid when closing with annular cover plate that starts to float cannot rise thus avoids liquid and enter
Enter inside ear washing bulb.
As preferably, coincideing bottom described Magnet base profile and sacculus, Magnet top is plane.
As preferably, described suction nozzle, relief valve, Magnet, mesa-shaped housing, annular cover plate, spherical float valve and the strong point are complete
Portion uses polytetrafluoroethylmaterial material to make.
This utility model has the beneficial effect that avoiding liquid sucks the problem within ear washing bulb, slow down ear washing bulb aging,
Extending service life, simple in construction, cost of manufacture is low, is worth promoting on a large scale.

[detailed description of the invention]
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and concrete
Embodiment, is further elaborated to this utility model.Should be appreciated that detailed description of the invention described herein is only used
To explain this utility model, it is not used to limit this utility model.
As Figure 1-3, this detailed description of the invention adopt the following technical scheme that it comprise sacculus 1, connecting portion 2, suction nozzle 3,
Relief valve 4, Magnet 5, mesa-shaped housing 41, annular cover plate 42, spherical float valve 43 and the strong point 44；Sacculus 1 is by connecting portion 2 and suction
Mouth 3 is bonded together, and is provided with Magnet 5 bottom sacculus 1, and suction nozzle 3 is internal is provided with relief valve 4, and relief valve 4 is by mesa-shaped housing 41, ring
Shape cover plate 42, spherical float valve 43 and the strong point 44 are constituted, and mesa-shaped housing 41 upper end arranges annular cover plate 42, and mesa-shaped housing 41 is internal
Setting can be freely up and down movable spherical float valve 43, spherical float valve 43 arranges 4 symmetrical strong points 44 respectively, the strong point 44
Design make spherical float valve 43 even at the free flow still having space can meet gas between least significant end and suction nozzle,
When liquid rises to the position of spherical float valve 43, spherical float valve 43 starts liquid when floating closes with annular cover plate 41 and cannot rise
Thus avoid liquid and enter inside ear washing bulb.
As preferably, coincideing bottom described Magnet 5 base profile and sacculus 1, Magnet 5 top is plane, and this makes to wash
Ear ball is conveniently placed in laboratory table without falling, and can also adsorb the surface of iron material simultaneously.
As preferably, described mesa-shaped housing 41, annular cover plate 42, spherical float valve 43 and the strong point 44 all use poly-four
Fluoride material is made.
The above, is only in order to the technical solution of the utility model to be described and unrestricted, those of ordinary skill in the art couple
Other amendment or equivalent that the technical solution of the utility model is made, without departing from technical solutions of the utility model
Spirit and scope, all should contain in the middle of right of the present utility model.
