Abstract

This patent belongs to laboratory heating field, specifically discloses a water -bath drainage lid. This water -bath drainage lid includes the ring cowling, and the drainage stick is installed to the lower extreme of ring cowling. The steam drop of water technical problem on sample container that drops has been solved to this kickboard, can reduce the contaminated probability of sample.

Description

Water-bath drain lid

Technical field

This utility model relates to laboratory heating art, is specifically related to a kind of water-bath drain lid.

Background technology

Water-bath is mainly used in laboratory to distill, dry, concentration, and temperature stain chemical drugs or biological product, it is also possible in heated at constant temperature and other temperature test, be food, biology, Aquatic product, environmental protection, medicine, etc. the indispensable instrument of field laboratory.The interior horizontal positioned rustless steel tubular heater of thermostat water bath (ThermostatWaterBath), the inside of tank is placed with aluminum shelf with holes.On cover the combination lasso being furnished with different bore, be suitable for the flask of different bore.There is adjutage on the left of water-bath, be electric box on the right side of thermostat water bath, equipped with temperature control instrument, on and off switch on electric box front panel.Electrothermal tube and sensor is had in electric box.Its operation principle is sensor is resistance value by the temperature transition of water trough inner water, through integrated amplifier amplification, compare after, export control signal, efficiently control the average heating power of electric heating tube, make water in tank keep constant temperature.When heated object requires to be heated evenly, when temperature is less than 100 DEG C, it is possible to use heating in water bath.Water-bath is made typically by copper or aluminum, and lid includes the circle of multiple overlap, is suitable to place the vessel of different size.

In practical operation, when test tube needs heating in water bath, being usually and test tube first inserts foam or in the plate hole of kickboard that plastics are made, is then placed in water-bath by kickboard, such test tube would not sink to the bottom of a pan, its underpart is heated in water, top is overlapped by kickboard, higher than liquid level, to a certain extent, the moisture in water-bath is avoided to enter in test tube, it is to avoid in pipe, sample is contaminated.But, the lower lid surface of water-bath would generally the little liquid pearl that is liquefied as of the much steam of coagulation, these little liquid pearls, along with the increase of volume, can drop on test tube, which increases the contaminated probability of heated sample.

Publication number is the Chinese patent document of CN201992833U, discloses one and facilitates push-and-pull lid water-bath, including pot and cleansing bath tub, it is characterized in that being provided with skewed slot in pot, be provided with pull plate in skewed slot.

But the edible skewed slot of this utility model fixes the position of pull plate, the globule dropped with pull plate drain.The area of pull plate can not accept residence on the one hand the globule dropped, and the container of lower section still has contaminated possibility；On the other hand, pull plate is not affixed on water-bath, when placing container or taking out container, relatively complicated.

Utility model content

The purpose of this utility model is in that to provide a kind of water-bath drain lid, to solve the technical problem that the steam globule drops on shuttle.

For reaching above-mentioned purpose, base case of the present utility model is: water-bath drain lid, and including ring cowling, the lower end of ring cowling is provided with conduction stick.

Operation principle and the advantage of this programme are in that: conduction stick changes the movement locus of the globule, the globule on ring cowling is made to be become along conduction stick landing from original dropping everywhere, as long as conduction stick does not contact with heating test tube, the globule would not drop on test tube, test tube lid would not be stained with the globule, thus reducing the contaminated probability of sample in test tube.

Preferred version one: based on the preferred version of scheme, be provided with the drain block of cone between conduction stick and ring cowling；The butt end of drain block and ring cowling are in removably connecting；The tip of drain block is hinged with conduction stick.The butt end of drain block is big with the contact area of ring cowling, and the collecting effect of the globule on ring cowling is better；The tip of the drain block of cone shape connects conduction stick and is easy to be pooled on conduction stick the globule；Drain block and ring cowling, in removably connecting, when the container of heating is bigger or higher, can dismantle next part drain block as required；Drain block is hinged with conduction stick, it is possible to regulate the direction of conduction stick, without, when dismantling drain block, only regulating the direction of conduction stick, it is possible to the effective position changing globule drippage.

Preferred version two: the preferably preferred version of: the butt end of drain block is provided with sucker.What sucker can facilitate consolidation is arranged on ring cowling, mounts and dismounts all very convenient.

Preferred version three: based on scheme, prioritization scheme one or preferred version two preferred version: conduction stick is made up of expansion link.The length of conduction stick so according to the height adding heat container, can be regulated easily, both played the effect of drain, and will not touch again and add heat container.

Accompanying drawing explanation

Fig. 1 is the structural representation of this utility model water-bath drain lid embodiment.

Detailed description of the invention

Below by detailed description of the invention, this utility model is described in further detail:

Accompanying drawing labelling in Figure of description includes: ring cowling 1, sucker 2, drain block 3, conduction stick 4.

Embodiment is substantially as shown in Figure 1:

Water-bath drain lid, including ring cowling 1, drain block 3 and conduction stick 4；Drain block 3 is cone, and the butt end of drain block 3 is provided with sucker 2, and sucker 2 and ring cowling 1 are in removably connecting；The tip of drain block 3 is hinged with conduction stick 4；Conduction stick 4 is made up of expansion link.

To heat test tube, test tube is inserted in the test tube fixing hole of water-bath, adjust the position of ring cowling, make the conduction stick of ring cowling lower end away from test tube, cover ring cowling, steam in such water-bath runs into the globule that the relatively low ring cowling of temperature is condensed into, and understands in along the outer wall stream of conduction stick to water-bath, does not fall out on test tube.

Container to be heated is placed in water-bath, lower end as needed in ring cowling 1 is dismantled or installs suitable drain block 3, adjust the position of ring cowling 1 and the length of conduction stick 4, conduction stick 4 is made not contact container to be heated, cover ring cowling 1, steam in such water-bath runs into temperature relatively low ring cowling 1 and condenses the globule being, first collected by cone shape drain block 3, it is pooled on conduction stick 4, then in along the outer wall stream of conduction stick 4 to water-bath, do not fall out on container, thus the contaminated probability of sample reduced in container.

Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the premise without departing from this utility model structure, it is also possible to make some deformation and improvement; these also should be considered as protection domain of the present utility model, and these are all without affecting effect and the practical applicability that this utility model is implemented.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. records the content that may be used for explaining claim.
