Description

A kind of thermostat water bath

Technical field

The utility model belongs to laboratory room small-sized equipment technical field, in particular to a kind of thermostat water bath.

Background technique

Water-bath is the commonly used small device of laboratory back warp, it is capable of providing uniform and stable temperature, therefore many Chemical reaction needs to carry out in water-bath, is mainly used for distillation in laboratory, dry, concentration and warm stain chemicals or biology Product, it can also be used to which heated at constant temperature and other humid tests, are biology, heredity, virus, aquatic products, environmental protection, medicine, health, chemical examination Room, analysis room, education and scientific research indispensable tool.In experiment detection process, chemical substance is usually firstly placed to a container In, then the container is put into the water in water-bath again, it is desirable that the part for filling chemical substance is completely immersed in water, to obtain Uniform and stable temperature is obtained, is that chemical reaction is gone on smoothly.But the existing most structure of water-bath is simple, has a single function, and uses And it safeguards all very inconvenient.

A kind of Chinese water-bath of CN201720877758.2 patent disclosure, including thermostat water bath ontology, in thermostatted water It is equipped with sink in bath ontology, is equipped with controller on the right side of thermostat water bath ontology, is equipped with heat block, institute in the bottom of sink The top for stating sink is equipped with top cover, and multiple collar aperture are equipped on top cover, handle is additionally provided on top cover；The inner wall of the sink applies There is good antiscale property layer, be additionally provided with low water level sensor on the inner wall of sink, is equipped with acousto-optic report in the upper end of thermostat water bath ontology Warning lamp, low water level sensor are connect with controller, and controller is connect with audible-visual alarm lamp.The utility model provides a kind of water-bath Pot, makes operator's operation and maintenance get up more convenient, does not easily cause device damage and safety accident.The water-bath cannot be to water Bath container is fixed, and due to the effect of buoyancy, causes water bath containers easily to tilt unstable, influences experimental result.

Chinese CN201721414129.2 patent discloses a kind of heat preservation water-bath of starvation, including pot body and pot It covers, is disposed with the first support plate and the second support plate in the pot body from bottom to up, the upper end of the first support plate is fixed to be connected Multiple first magnet blocks are connected to, multiple conical flasks are provided with above the second support plate, the bottom of bottle of multiple conical flasks is fixed to be connected Multiple second magnet blocks are connected to, the upper end of pot body is provided with pot cover, and the upper end two sides of pot cover are respectively arranged with inert gas air inlet Glass window is rabbeted at the middle part of pipe and escape pipe, pot cover, and pot and pot cover are made of stainless steel internal layer and stainless steel outer layer, Insulating layer is provided between stainless steel internal layer and stainless steel outer layer, the utility model simple structure and reasonable design, conical flask is in pot It is less likely to occur to shake in vivo, guarantees heating effect, while inert gas can be passed through, be suitble to oxidizable material and light sensitivity object The reaction of material, it is functional more.The water-bath is closed environment during water-bath, and the intracorporal humidity of case is larger, for water More sensitive material is affected.

The existing most structure of water-bath is simple, and generally directly reaction vessel is placed in water-bath and is reacted, nothing Water-bath is fixed in method, causes to need manually to help container surely when water-bath, time-consuming and laborious；Secondly, general water-bath into It is connected when row water-bath operates with atmosphere, while the water heated is directly evaporated in air, the reactive material more active for property Physical property is easily influenced during water-bath, causes biggish experimental error.Therefore, it is badly in need of designing a kind of thermostat water bath to solve The certainly above problem.
