Example (b): referring to fig. 1, 2 and 3, the constant temperature water bath kettle comprises a box body 1, a cover body 2, a partition layer 3 arranged in the box body 1, a heating element 4 and a partition layer inclined assembly. The box body 1 can be a rectangular box body structure in the prior art and is provided with a water inlet and a water outlet; the cover body 2 can be a structure which is provided with a plurality of placing holes and is matched with a plurality of pot covers in the prior art, and can also be an integral cover body; the interlayer 3 can adopt a structure in the prior art, such as a metal screen plate or a metal plate provided with a plurality of water filtering holes, in the embodiment, a certain gap (such as 1-2 cm) is formed between the interlayer 3 and the peripheral inner wall of the box body 1 so as to ensure that the inclination of the interlayer 3 is not hindered; the heating element 4 may be any one of the prior art structures capable of heating water, such as a U-shaped electric heating tube.

The interlayer tilting assembly is used for lifting and tilting the interlayer when a sample needs to be taken out, so that the sample can automatically slide out through the discharge port under the action of self weight. Specifically, the interlayer tilting assembly comprises a lifting unit 51 which is pivoted with the interlayer 3 and used for enabling the interlayer 3 to ascend and descend, and a first limiting unit 52 and a second limiting unit 53 which are respectively arranged on a first side edge part C and a second side edge part D of the interlayer 3, wherein the first side edge part C and the second side edge part D are two opposite edge parts of the interlayer 3, and the first side edge part C and the second side edge part D are two long edges (in the width direction of the box body 1) of the interlayer 3; when the lifting unit 51 lifts the interlayer 3, the first limiting unit 52 limits the height of the first side edge part at a first height, and the second limiting unit 53 limits the height of the second side edge part at a second height, wherein the first height is lower than the second height; the side wall of the box body 1 corresponding to the first side edge is provided with a discharge port 8, and the discharge port 8 is sealed through a turnover door 9. The upper part of the turnover door 9 is pivoted on the box body 1, so that the turnover door 9 can be turned over and opened under the action of the dead weight of a sample.

Borrow by above-mentioned structure, through the setting of interlayer slope subassembly to when needs sample, lift unit 51 promotes the interlayer, and first spacing unit 52 restricts the promotion height of the first side portion C of interlayer 3 at first height, and second spacing unit 53 restricts the promotion height of the second side portion D of interlayer 3 at second height department, because first height department is less than second height department, so interlayer 3 takes place the slope, thereby the sample slides out in the discharge gate through the corresponding setting with first side portion C under the effect of dead weight. Therefore, an operator does not need to open the pot cover (or the whole cover body) for sampling in a short distance, allergy caused by the fact that the operator is close to hot gas with substances which are easy to cause allergy can be effectively avoided, the experimental environment is improved, and the health of the operator is facilitated.

Referring to fig. 3 and 4, a first movable hole 31 is formed in the first side edge portion C, the first limiting unit 52 includes a first guide rod 521 passing through the first movable hole 31, a first height limiting block 522 welded and fixed to the top of the first guide rod 521, and a first placing block 523 welded and fixed to the first guide rod 521, and the first placing block 523 is located below the first height limiting block 522; a second movable hole 32 is formed in the second side edge portion D, the second limiting unit 53 includes a second guide rod 531 penetrating through the second movable hole 32, a second height limiting block 532 welded and fixed to the top of the second guide rod 531, and a second placing block 533 welded and fixed to the second guide rod 531, and the second placing block 533 is located below the second height limiting block 532; the first guide rod 521 and the second guide rod 531 are fixed to the bottom of the box 1 by welding. Thus, the first height limiter 522 and the second height limiter 532 are formed at the first height and the second height, respectively. In consideration of the stable movement of the interlayer 3, the distance between the first height limiting block 522 and the first placing block 523 is 3-5 times the thickness of the interlayer 3, and the distance between the second height limiting block 532 and the second placing block 533 is set to be suitable for enabling the interlayer 3 to incline enough, namely ensuring that the sample can slide out under the action of self weight.

In this embodiment, the first side portion C is symmetrically provided with 2 first movable holes 31, the second side portion D is symmetrically provided with 2 second movable holes 32, and the positions of the first side portion C and the second side portion D are determined by the cooperation of the pair of first limiting units 52 and the 2 first movable holes 31 and the cooperation of the pair of second limiting units 53 and the 2 second movable holes 32. Since the first height limiting block 522 and the second height limiting block 532 are respectively formed at the first height position and the second height position, when the interlayer 3 is lifted, the interlayer 3 is in an inclined state, and a sample placed on the interlayer slides to the first side edge part C under the action of self weight. Preferably, there is a gap (e.g. 1-2 cm) between the first movable hole 31 and the first guide rod 521 and between the second movable hole 32 and the second guide rod 531, so as to ensure that the inclination of the partition 3 is not hindered.
