Detailed ways

The specific embodiments of the present utility model will be described in further detail below in conjunction with the accompanying drawings.

As shown in Figure 1-3, the utility model includes an upper base, a lower base, an electric heating plate, a ventilation pipe and an electric fan, the lower base 2 is equipped with ventilation pipes 4 at equal intervals, and a support frame is arranged between the upper base 1 and the lower base 2 6. The supporting frame 6 corresponds to the ventilation pipe 4 one by one. The connecting ring 8 is set on the supporting frame 6. The clip 7 perpendicular to the supporting frame 6 is installed on the connecting ring 8. The clip 7 is located directly above the ventilation pipe 4. The lower base 2 An electric fan 5 is housed inside, and an electric heating plate 3 is housed in the lower base 2 above the electric fan 5 , and through holes are evenly distributed on the side walls of the ventilation pipe 4 .

In order to ensure the use effect, the ventilation pipe 4 is a cylinder made of 316L stainless steel with a length of 2cm and a diameter of 8mm.

The bottom of the ventilation pipe is provided with an external thread joint, which is screwed and fixed with the internal thread of the lower base 2 .

The diameter of the through hole is 2mm.

The electric fan 5 is a DC turbofan.

The clip 7 is composed of a handle and a chuck made of galvanized steel. The length of the handle is 28 cm. The chuck is installed at the front end of the handle.

Both the upper seat 1 and the lower base 2 are hollow cuboids made of stainless steel.

The support frame 6 is a cylinder made of stainless steel.

The usage of the present utility model is that when the instrument needs to be heated, first put the cleaned instrument on the clamp 7, then fix it with an external thread joint, adjust the height of the clamp 7 on the support frame 6 to make it reach a suitable The height allows the fixed ventilation pipe 4 of the lower base to stretch into the inside of the instrument for drying. Then connect the power supply, the electric fan 5 and the electric heating plate 3 start to work, the electric heating plate 3 heats the air, generates hot air, and the electric fan 5 blows the hot air to move upwards into the ventilation pipe 4, and then blows it through the through hole on the ventilation pipe 4. To the inner wall of the instrument for drying. When there are few instruments that need to be heated, the base of the unnecessary ventilation pipe 4 can be blocked with a stainless steel external thread joint, so as to reduce unnecessary heat loss and save energy consumption. When it is found that the water drop inside the instrument disappears, turn off the power, then adjust the height of the clamp 7 upward along the support frame, loosen the external thread joint, and finally take out the instrument.

The electric fan 5 of the utility model adopts a small DC turbofan, which occupies a small volume and has higher efficiency. The clip 7 is a commercially available product (Beijing Tianlian Harmony Instrument Factory), the material is galvanized steel, and the total length is 28cm (medium ), the clamping range is 1.5㎝ to 8㎝, and the connecting ring 8 is set on the support frame, which can move up and down on the support frame (it can be considered to use the principle of magnetic attraction to make the connecting ring a magnetic substance, so that it can be compatible with the The support frames are tightly attracted to each other, and it is easier to slide up and down). The ventilation pipe and the lower base are connected through internal and external threads, the lower base is a stainless steel internal thread type, and the bottom of the ventilation pipe is provided with a stainless steel external thread joint of matching specifications.

The utility model has the advantage of avoiding the contact between the instrument and the ventilation pipe, thereby ensuring that the dust on the ventilation pipe 4 will not stick to the inner wall of the instrument during drying compared with the currently used drying device, and ensuring that the instrument is heated during the heating process. The utility model is easy to operate, small in size, low in cost, fast in drying, not easy to pollute, and good in use effect. It is especially suitable for the drying of small-scale laboratory glass instruments that are ready to be washed and used, which greatly improves the experimental efficiency. It is the first choice on the drying device Innovation has good economic and social benefits.
