Description

Technical Field

[0001] The utility model relates to the technical field of experimental heating instruments, in particular to a water bath pot. Background Art

[0002] Water bath is a common heating equipment in laboratories. It is mainly used for distillation, drying, concentration, and soaking of chemicals and biological products in laboratories. It can also be used for constant temperature heating of other temperature tests. It is an essential tool for biology, genetics, laboratories, analysis rooms, and education and scientific research. Nowadays, water baths need to be loaded with different types of vessels, but the vessels are of different sizes. If the vessels are not fixed, they are prone to shaking during the distillation or disinfection process, affecting the heating effect.

[0003] Referring to the prior art CN218359348U-a water bath pot comprises a pot seat body, a control panel is installed on the outer side of the pot seat body, a plurality of heating chambers are arranged at equal distances inside the pot seat body, and a heating mechanism is arranged inside the heating chamber, the heating mechanism comprises a water tank and a first water pipe, a fixing mechanism is installed inside the heating chamber, and the fixing mechanism is specifically a fixing clip disclosed in the embodiment.

[0004] The prior art uses a fixing clamp to clamp the vessel for fixing. However, it is found during use that if the fixing clamp is small, it is impossible to effectively clamp the vessel. Therefore, it is necessary to increase the clamping area of ​​the vessel by the fixing clamp. However, the area where the fixing clamp clamps the vessel is blocked by the fixing clamp, resulting in the inability to effectively transfer heat to the liquid in the vessel in this area, causing uneven heating. However, uneven heating will bring many problems. For example, when the microbial (bacterial) reagent is heated and cultivated in a low-temperature water bath, the uneven heating will affect the metabolic rate of the microorganism and the activity of the intracellular enzymes, causing the bacterial growth rate to slow down or stagnate, and may also cause changes in the morphology of the bacterial colony, thereby affecting the judgment of the type and quantity of bacteria. Therefore, it is necessary to solve the problem of uneven heating. Utility Model Content

[0005] The utility model aims to provide a water bath pot to solve the problem in the prior art that the clamping area of ​​the vessel is blocked by the fixing clamp, resulting in the inability to effectively transfer heat in the area and causing uneven heating.

[0006] In order to solve the above problems, the utility model provides the following technical solutions:

[0007] A water bath pot comprises a pot body, wherein the interior of the pot body is symmetrically provided with sliding grooves, wherein the sliding grooves are vertically slidably connected with an inverted L-shaped connecting frame, wherein the sliding grooves are fixedly provided with a cylinder for driving the connecting frame to slide, and the opposite ends of the connecting frames on both sides are commonly connected with a placement plate located in the pot body; the placement plate is provided with a plurality of clamping mechanisms, wherein the clamping mechanisms comprise a fixed plate and a clamping plate slidably connected with the placement plate, wherein the fixed plate and the placement plate are fixedly connected, and a spring is fixedly provided between the clamping plate and the connecting frame; the pot body is provided with a cover body, wherein the cover body is fixedly provided with a motor used in conjunction with each clamping mechanism, wherein the motor drives a stirring shaft passing through the cover body, and the stirring shaft is fixedly sleeved with a stirring blade located between the corresponding clamping plate and the fixed plate.

[0008] The working principle and beneficial effects of the utility model:

[0009] The present invention removes the cover body, and since the sliding groove is slidably connected with an inverted L-shaped connecting frame, the sliding groove is fixedly provided with a cylinder for driving the connecting frame to slide, and the opposite ends of the connecting frames on both sides are commonly connected with a placing plate, so the connecting frame is driven upward by the cylinder to move, and the connecting frame drives the placing plate to rise upward; and the placing plate is provided with a plurality of clamping mechanisms, each clamping mechanism includes a fixed plate and a clamping plate slidably connected to the placing plate, a spring is provided between the clamping plate and the placing plate, and the fixed plate and the placing plate are fixedly connected, and the clamping plate is pulled to move to compress the spring, and the vessel is placed between the clamping plate and the fixed plate of the clamping mechanism, and the clamping plate is slowly released, so that the elastic force of the spring clamps the vessel between the clamping plate and the fixed plate. After all the vessels are clamped, the cylinder drives the placing plate to move downward to the bottom of the pot body, and then water is added to the pot body to a certain liquid level, and the cover body is covered for heating, and the stirring blade fixedly sleeved on each stirring shaft is located directly above the corresponding vessel.

[0010] After a period of water bath heating, the connecting frame is driven upward by the cylinder, and the connecting frame drives the placement plate and all the containers to move upward, so that each stirring blade extends into the liquid in the corresponding container, and then the motor is started to drive the stirring blade to rotate through the stirring shaft. The stirring blade stirs the liquid in the container at a low speed, so that the heat of the liquid in the container is evenly mixed. Repeat the above process several times to complete the heating. Finally, take out the cover body, drive the connecting frame upward by the cylinder, and drive the placement plate and all the containers to move upward. After the container cools down, pull it to the clamping plate to compress the spring and remove the container.

[0011] When the vessel is heated in the present application, the stirring blade is located outside the vessel, so as not to affect the heat transfer between the liquids inside the vessel. At the same time, after heating for a period of time, the placement plate rises so that the stirring blade extends into the liquid level of the vessel for stirring, so that the heat of the liquid in the vessel is evenly mixed, thereby solving the problem of uneven heating in the prior art and improving the water bath heating effect.

[0012] Furthermore, a plurality of the clamping mechanisms are evenly spaced on the placement plate, so that the heating space of each vessel can be evenly distributed, thereby improving the water bath heating effect.

[0013] Furthermore, the stirring blades are distributed in a serpentine shape on the stirring shaft. The stirring blades distributed in a serpentine shape can improve the stirring effect.

[0014] Furthermore, the pot body is provided with a groove connected to the sliding groove. The groove provides a space for the connecting frame to slide up and down, so that the space for the placement plate to move up and down is larger, so that the stirring blade can extend into the bottom of the vessel.

[0015] Furthermore, the placement plate is provided with a positioning groove between each clamping plate and the fixing plate of the clamping mechanism, which is conducive to the positioning groove to perform preliminary positioning on the placement position of the vessel, and the positioning groove also plays a certain role in fixing the vessel.

[0016] Furthermore, the sliding groove and the cover body are both provided with a heat insulation layer, which is used to isolate heat transfer to prevent affecting the service life of the cylinder and the motor. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In the following statements, directional words such as "left", "right", "up", and "down" are all based on the directions shown in the diagram. In practice, if the corresponding structures are changed in the same direction based on the directions while keeping the relative positions unchanged, it will not affect the implementation of the plan.

[0024] Embodiment: A water bath, such as Figure 1As shown, it includes a pot body 8, the interior of the pot body 8 is symmetrically provided with sliding grooves 9, the sliding grooves 9 are vertically slidably connected with an inverted L-shaped connecting frame 7, the sliding grooves 9 are fixed with a cylinder 6 for driving the connecting frame 7 to slide, and the pot body 8 is provided with a groove 12 connected to the sliding grooves 9.

[0025] The opposite ends of the two side connecting frames 7 are commonly connected to a placement plate 15 located inside the pot body 8. The width of the placement plate 15 is smaller than the width of the pot body 8. For example, when the width of the pot body 8 is 50 cm, the width of the placement plate 15 is 30 cm. This arrangement is beneficial for the heating rod 5 to heat the water inside the pot body 8 to prevent the placement plate 15 from occupying a large amount of space inside the pot body 8.

[0026] The placement plate 15 is provided with two clamping mechanisms, such as Figure 4 As shown, the clamping mechanism includes a fixed plate 4 and a clamping plate 3 horizontally slidably connected to a placement plate 15, the fixed plate 4 and the placement plate 15 are fixedly connected, and a spring 1 is fixedly provided between the clamping plate 3 and the connecting frame 7; the pot body 8 is provided with a cover body 13, and the cover body 13 is fixedly provided with a motor 10 used in conjunction with each clamping mechanism, the motor 10 drives a stirring shaft 11 passing through the cover body 13, and the stirring shaft 11 is fixedly sleeved with a stirring blade 14 located between the corresponding clamping plate 3 and the fixed plate 4.

[0027] like Figure 1 As shown, in this scheme, the cover body 13 is removed. Since the sliding groove 9 is slidably connected with the inverted L-shaped connecting frame 7, the sliding groove 9 is fixedly provided with a cylinder 6 for driving the connecting frame 7 to slide, and the opposite ends of the connecting frames 7 on both sides are commonly connected with a placement plate 15. Therefore, the connecting frame 7 is driven to move upward by the cylinder 6, and the connecting frame 7 drives the placement plate 15 to rise upward; and the placement plate 15 is provided with two clamping mechanisms, each of which includes a fixed plate 4 and a clamping plate 3 slidably connected to the placement plate 15, and a spring 1 is provided between the clamping plate 3 and the placement plate 15, and the fixed plate 4 and the placement plate 15 are fixedly connected. The clamping plate 3 is pulled to compress the spring 1, and the vessel 2 is placed between the clamping plate 3 and the fixed plate 4 of the clamping mechanism, and the clamping plate 3 is slowly loosened, which is conducive to the elastic force of the spring 1 to clamp the vessel 2 between the clamping plate 3 and the fixed plate 4. After all the vessels 2 are clamped, as shown in FIG. Figure 2 As shown, the cylinder 6 drives the placement plate 15 to move downward to the bottom of the pot body 8, and then water is added to the pot body 8 to a certain water level, and the cover 13 is covered for heating. The stirring blade 14 fixedly sleeved on each stirring shaft 11 is located directly above the corresponding vessel 2.

[0028] like Figure 3As shown, after a period of water bath heating, the connecting frame 7 is driven upward by the cylinder 6, and the connecting frame 7 drives the placement plate 15 and all the containers 2 to move upward, so that each stirring blade 14 extends into the liquid in the corresponding container 2, and then the motor 10 is started to drive the stirring blade 14 to rotate rapidly through the stirring shaft 11, and the stirring blade 14 stirs the liquid in the container 2, generating a vortex to mix the upper liquid and the bottom liquid, so that the heat of the liquid in the container 2 is evenly mixed, and the above process is repeated several times to complete the heating. Finally, the cover 13 is removed, and the connecting frame 7 is driven upward by the cylinder 6 to move upward, and the connecting frame 7 drives the placement plate 15 and all the containers 2 to move upward. After the container 2 cools down, it is pulled to the clamping plate 3 to compress the spring 1 and remove the container 2.

[0029] In the present application, when the vessel 2 is heated, the stirring blade 14 is located outside the vessel 2, so as not to affect the heat transfer between the liquids inside the vessel 2. At the same time, after heating for a period of time, the placement plate 15 is raised so that the stirring blade 14 extends into the liquid in the vessel 2 for stirring, thereby stirring the liquid in the clamping area, so that the heat of the liquid in the vessel 2 is evenly mixed, thereby improving the water bath heating effect.
