Detailed Description

The present invention is described in terms of specific embodiments, and other advantages and benefits of the present invention will become apparent to those skilled in the art from the following disclosure. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

An automatic sample concentrator, as shown in fig. 1 and 2, comprises a housing 1, a bath heater 2 and a ventilator 3. The ventilation device 3 includes an air pump 31, a ventilation pipe 32, a lifting mechanism 33, a ventilation plate 34, and a gas distribution pipe 35.

Air pump 31 installs in casing 1, because breather pipe 32 need carry out the lift and ventilate two kinds of functions, in order to realize its automatic rising, this application adopts the slider of joining and breather pipe 32 and links to each other, drives its lift through the slider and links to each other with its air pump 31 through the slider, breather pipe 32 has just so realized ventilating simultaneously and two kinds of functions of automatic rising, specifically as follows:

as shown in fig. 2 and 3, the lifting mechanism 33 includes an electric push rod 331, a support slider 332 and a guide post 333, the electric push rod 331 is installed in the housing 1 and includes a movable end, the upper end of the movable end is connected to the housing 1, the movable end of the electric push rod 331 is a screw rod, and the support slider 332 is horizontally screwed on the movable end of the electric push rod 331. The guide post 333 is vertically inserted into the support slider 332, the base 11 is mounted at the bottom of the housing 1, the base 11 is connected with the housing 1 through four legs, the lower end of the guide post 333 is mounted on the base 11, and the upper end is mounted on the top of the inner wall of the housing 1. The supporting slide block 332 is hollow, the lower end of the vent pipe 32 is communicated with the inside of the supporting slide block 332, the upper end of the vent pipe extends out of the shell 1, the guide sleeve 12 is installed at the top of the shell 1, the middle part of the vent pipe 32 is inserted into the guide sleeve 12, and the guide sleeve 12 plays a role in guiding the vent pipe.

Because the breather pipe 32 goes up and down through the supporting slide block 332, the outside of the breather pipe 32 does not need to be sleeved with components such as a breather pipe sleeve, and the structure is simpler.

When the electric push rod 331 works, the support slide block 332 vertically moves up and down under the limit of the guide post 333, and drives the vent pipe 32 to lift up and down. The spiral vent pipe 36 is connected between the support slider 332 and the air pump 31, when the support slider 332 ascends, the spiral vent pipe 36 gradually expands, and when the support slider 332 descends, the spiral vent pipe 36 gradually contracts and recovers to the original state, so that the spiral vent pipe 36 can effectively transmit the air flow blown out by the air pump 31.

The upper end of the vent tube 32 communicates with the interior of the vent panel 34. The aeration plate 34 is horizontally arranged, the gas distribution pipes 35 are vertically arranged, the upper ends of the gas distribution pipes are communicated with the inside of the aeration plate 34, the positions of the aeration pipes 32, which correspond to the upper part of each gas distribution pipe 35, are respectively provided with a gas speed regulation control valve 341, the gas speed regulation control valves 341 are connected with the gas distribution pipes 35, and the flow speed of gas in the gas distribution pipes 35 is controlled by controlling the ventilation sectional area of the upper ends of the gas distribution pipes 35. When no reagent tube is arranged at a position corresponding to a certain gas distribution tube 35 on the bath heating device 2, the gas distribution tube 35 is sealed by rotating the screw cap on the gas speed regulation control valve 341 on the corresponding gas distribution tube 35, so that the waste of the power of the air pump 31 is avoided.

As shown in fig. 2 and 4, the existing concentration instrument adopts water bath heating, but the water transfer heat is slow, and the water needs to be heated before bath heating, and the water heating is slow, and the efficiency is low. The method comprises the following specific steps: the bath heating device 2 comprises a heating box body 21 and a metal heating sleeve 22, wherein the heating box body 21 is installed on the shell 1, the metal heating sleeve 22 is installed on the heating box body 21, and the inner diameter of the metal heating sleeve is the same as the outer diameter of the reagent tube. Each gas distribution pipe 35 is arranged corresponding to one metal heating sleeve 22, and a test tube positioning frame 23 is installed above the metal heating sleeve 22 through screws.

After putting into the reagent pipe in the metal heating jacket 22, paste with the inside wall of metal heating jacket 22, electric putter 331 drives breather pipe 32, air-breather plate 34 and gas-distributing pipe 35 automatic descending, and gas-distributing pipe 35 ventilates to the reagent intraductal for the rapid evaporation of the intraductal reagent of reagent, because the reagent pipe directly heats through metal heating jacket 22, efficiency is higher.

The workstation that links to each other with electric putter 331 is installed to the front side of shell, and the workstation includes display screen 4 and button for show various bathed hot data, and the button is total three, is used for controlling the ascending of gas-distributing pipe 35, the decline of gas-distributing pipe 35 and the opening and close of bathed hot device 2 respectively, convenient operation.

Although the invention has been described in detail with respect to the general description and the specific embodiments, it will be apparent to those skilled in the art that modifications and improvements can be made based on the invention. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
