DETAILED DESCRIPTION

[0023] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0024] according to Figure 1 , 2 As shown in , 3, 4, and 5, this embodiment provides a water bath device for biological experiments that is convenient for loading and unloading test tubes, including a pot body 1, a pot cover 2 is provided at the upper end of the pot body 1, and a plurality of container placement openings 3 are opened on the pot cover 2, and each container placement opening 3 is provided with a circular cover 4;

[0025] A support structure is provided inside the pot body 1, and at least two perforated plates 13 are provided on the support structure. The perforated plates 13 are stacked up and down, and a plurality of through holes 14 are provided on the perforated plates 13; the vessel to be heated is placed into the upper end of the topmost perforated plate 13 inside the pot body 1 through the vessel placement opening 3, and the reagent tube to be heated is inserted into the through hole 14 provided on the perforated plate 13. The advantage of providing a plurality of perforated plates 13 is that the reagent tube can be more stable when placed.

[0026] The support structure includes a U-shaped handle 7 provided at both ends of the perforated plate 13, the lower end of the U-shaped handle 7 penetrates each perforated plate 13, the U-shaped handle 7 is slidably connected to the perforated plate 13, and a positioning component is provided at the connection between the perforated plate 13 and the U-shaped handle 7. After releasing the lock of the perforated plate 13 by the positioning component, the height of the perforated plate 13 can be adjusted to meet the placement requirements of reagent tubes of different lengths, and the applicability is wide. When taking and placing the perforated plate 13, the perforated plate 13 can be pulled by holding the upper end of the U-shaped handle 7, and the staff does not need to put their hands into the water in 1, which is highly practical.

[0027] Specifically, the positioning assembly includes a plurality of nuts 16 sleeved on the outside of the U-shaped handle 7, each nut 16 is respectively placed on the upper end face and the lower end face of the perforated board 13, and the nut 16 is threadedly connected with the external thread 15 provided on the outside of the U-shaped handle 7, and each nut 16 is respectively arranged on each corner of the perforated board 13. By rotating the nut 16 and adjusting the position between the two nuts 16 at the upper and lower ends of the perforated board 13, the height of the perforated board 13 can be adjusted. The nut 16 located on the upper end face of the perforated board 13 limits the perforated board 13 from the upper end of the perforated board 13, and the nut 16 located on the lower end face of the perforated board 13 limits the perforated board 13 from the lower end of the perforated board 13. In order to reduce the friction between the contact surface of the nut 16 and the perforated board 13 and protect the nut 16 and the perforated board 13, a gasket 17 is provided on the side of the nut 16 facing the perforated board 13, and the gasket 17 is sleeved on the outside of the U-shaped handle 7, and the gasket 17 is fixedly connected to the nut 16. When the nut 16 approaches the perforated plate 13 , the gasket 17 will first contact the upper and lower end surfaces of the perforated plate 13 to share the pressure on the contact surface between the nut 16 and the perforated plate 13 , thereby increasing the service life of the nut 16 and the perforated plate 13 .

[0028] In order to prevent the U-shaped handle 7 from bumping against the inner wall of the pot body 1 when it is placed, a rubber block 18 is provided at the lower end of the U-shaped handle 7, and a threaded column 19 is provided at the upper end of the rubber block 18. The threaded column 19 is inserted into the lower end of the U-shaped handle 7, and the threaded column 19 is threadedly connected to the inner wall of the U-shaped handle 7. The rubber block 18 is fixed to the lower end of the U-shaped handle 7 by threaded connection, and can protect the inner wall of the pot body 1 without affecting the removal of the perforated board 13.

[0029] Regarding the U-shaped handle 7: a handle slot 5 is provided on the pot cover 2, the upper end of the U-shaped handle 7 passes through the handle slot 5, and the top of the U-shaped handle 7 extends through the handle slot 5 to above the pot body 1. In order to ensure the seal between the pot cover 2 and the pot body 1, a strip cover 6 is provided on the handle slot 5, and the strip cover 6 and the U-shaped handle 7 are staggered.

[0030] In order to facilitate the experimenter to hold the U-shaped handle 7, a rubber sheath 12 is provided on the upper end of the U-shaped handle 7, and the rubber sheath 12 is sleeved on the outside of the U-shaped handle 7, and the rubber sheath 12 is fixedly connected to the U-shaped handle 7. The rubber sheath 12 increases the friction between the hand and the U-shaped handle 7, and also improves the comfort of holding the U-shaped handle 7.

[0031] In order to facilitate the experimenter to take the circular cover 4 and the strip cover 6, the upper ends of the circular cover 4 and the strip cover 6 are provided with rubber balls 11, and each rubber ball 11 is respectively fixedly connected to each circular cover 4 and each strip cover 6. When the circular cover 4 is removed from the vessel placement opening 3 and the strip cover 6 is removed from the handle slot 5, the rubber ball 11 can be held to take and place.

The electric heating tube 8 and the drain port 9 are both provided at the bottom of the pot body 1, and the electric heating tube 8 is staggered with the U-shaped handle 7, and the drain port 9 is connected to the drainage pipe provided outside the pot body 1. The electric heating tube 8 is immersed in the pot body 1, and converts electricity into thermal energy through the electrothermal effect to heat the water in the pot body 1. In addition to the electric heating tube 8, a temperature sensor is also provided in the pot body 1. The temperature sensor can sense the real-time temperature of the water in the water tank and convert the temperature information into a change in resistance value. This change in resistance value is amplified by an integrated amplifier and processed by a comparison circuit to form a feedback signal. The temperature controller receives this feedback signal to determine whether the current water temperature reaches the set value, thereby adjusting the temperature.

[0033] Working principle: The vessel to be heated is placed into the upper end of the topmost perforated board 13 in the pot body 1 through the vessel placement port 3, and the reagent tube to be heated is inserted into the perforation 14 provided on the perforated board 13. The multi-layer perforated board 13 can increase the stability of the reagent tube when placed. Each nut 16 is arranged on each corner of the perforated board 13. By turning the nut 16 and adjusting the position between the two nuts 16 at the upper and lower ends of the perforated board 13, the height of the perforated board 13 can be adjusted. In this way, the placement requirements of reagent tubes of different lengths can be met, and the applicability is wide. When taking and placing the perforated board 13, the perforated board 13 can be pulled by holding the upper end of the U-shaped handle 7, and the staff does not need to put their hands into the water in the pot body 1.
