Description

Technical Field

[0001] This utility model relates to the field of heating equipment technology, specifically to an electric thermostatic water bath with a stirring structure. Background Technology

[0002] In scientific experiments and industrial production, constant-temperature water baths are widely used as important heating equipment for sample heating, chemical reactions, and material processing. Their constant temperature characteristic provides stable environmental conditions for experiments and production, ensuring the accuracy of experimental results and the consistency of production quality. However, traditional constant-temperature water baths suffer from uneven heating of the liquid during the heating process. The lack of an effective stirring structure results in higher liquid temperatures near the heating element and lower temperatures in areas further away, affecting the accuracy and consistency of experimental results. Regarding fixing methods, most existing products use simple placement or weak clips for fixation. During operation, the water bath body may shift, affecting experimental operations and posing safety hazards. Utility Model Content

[0003] The purpose of this invention is to provide an electric thermostatic water bath with a stirring structure to solve the problems of uneven heating and poor fixation in existing thermostatic water baths mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An electric thermostatic water bath with a stirring structure includes a water bath body and a base for fixing the water bath body. Side seats are symmetrically arranged on both sides of the top surface of the base, and clamping cylinders for locking the water bath body are installed on the outer wall of the middle part of the two sets of side seats.

[0006] A servo stirring motor is embedded in the center of the top surface of the base;

[0007] A stirring shaft is installed at the center of the bottom of the water bath body. Several sets of stirring blades are connected to the stirring shaft. Several sets of constant temperature electric heating rods made of PTC heating ceramic tubes are installed in the water bath body. The constant temperature electric heating rods are located above the stirring blades.

[0008] A sealed bearing for fixing the stirring shaft is embedded in the center of the bottom of the water bath body, and the rotating shaft of the servo stirring motor is inserted into the bottom of the stirring shaft.

[0009] Preferably, the bottom openings of both the rotating shaft and the stirring shaft have square cross-sections.

[0010] Preferably, the bottom of the side seat is mounted to both sides of the top surface of the base via connecting feet.

[0011] Preferably, the clamping cylinder is connected to the outer wall of the side seat, and the piston rod of the clamping cylinder passes through the side seat and is coaxially connected to the clamping disc.

[0012] Preferably, the side surface of the clamping disc that contacts the water bath body is provided with several uniformly spaced anti-slip protrusions.

[0013] Preferably, the anti-slip protrusions are made of silicone and the height of the protrusions is 1-3mm.

[0014] Preferably, the outer wall of the water bath body is provided with a heat-insulating shell.

[0015] Compared with existing technologies, the beneficial effects of this utility model are:

[0016] 1. In this electric thermostatic water bath with stirring structure, the base and side seats provide stable support for the water bath body; the clamping cylinder can lock the water bath body to ensure its stability during operation; the servo stirring motor drives the stirring blade to rotate through the insertion and cooperation of the rotating shaft with the stirring shaft, stirring the liquid in the water bath body and making the liquid heated more evenly; the sealed bearing fixes the stirring shaft to prevent liquid leakage; the thermostatic heating rod is made of PTC heating ceramic tube and is located above the stirring blade, which can heat the liquid at a constant temperature. Thus, this electric thermostatic water bath with stirring structure has the functions of stable support, reliable fixation, uniform stirring and constant temperature heating, which meets the needs of liquid heating and stirring in relevant experiments or production processes.

[0017] 2. In this electric thermostatic water bath with stirring structure, the clamping cylinder is connected to the outer wall of the side seat. The piston rod of the clamping cylinder passes through the side seat and is coaxially connected to the clamping plate. Through the clamping cylinder, piston rod and clamping plate, when the clamping cylinder is working, the piston rod can drive the clamping plate to move, thereby clamping or releasing the water bath body, which facilitates the installation and disassembly of the equipment.

[0018] 3. In this electric thermostatic water bath with stirring structure, the surface of the clamping plate that contacts the water bath body is provided with several uniformly spaced anti-slip protrusions. The anti-slip protrusions are made of silicone and the height of the protrusions is 1-3mm. The silicone anti-slip protrusions increase the friction when the clamping plate contacts the water bath body, preventing the water bath body from shifting after clamping. At the same time, the silicone material has a certain elasticity and will not damage the outer wall of the water bath body. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

[0029] An electric thermostatic water bath with a stirring mechanism, such as Figures 1-3As shown, the system includes a water bath body 40 and a base 10 for fixing the water bath body 40. Side seats 20 are symmetrically arranged on both sides of the top surface of the base 10. Clamping cylinders 30 for locking the water bath body 40 are installed on the outer wall of the middle of the two sets of side seats 20. A servo stirring motor 11 is embedded in the center of the top surface of the base 10. A stirring shaft 42 is installed in the center of the bottom inside the water bath body 40. Several sets of stirring blades 45 are connected to the stirring shaft 42. Several sets of uniformly spaced, equidistant constant-temperature heating rods 43 made of PTC heating ceramic tubes are installed inside the water bath body 40, with the heating rods 43 positioned above the stirring blades 45. A sealed bearing 44 for fixing the stirring shaft 42 is embedded in the center of the bottom inside the water bath body 40. The rotating shaft 12 of the servo stirring motor 11 is connected to the bottom of the stirring shaft 42. The water bath body 40 is stably supported by the base 10 and side seat 20. The clamping cylinder 30 locks the water bath body 40 to ensure its stability during operation. The servo stirring motor 11 is connected to the stirring shaft 42 via the rotating shaft 12, which drives the stirring blade 45 to rotate and stir the liquid in the water bath body 40, making the liquid heat more evenly. The sealed bearing 44 fixes the stirring shaft 42 to prevent liquid leakage. The constant temperature electric heating rod 43 is made of PTC heating ceramic tube and is located above the stirring blade 45. It can heat the liquid at a constant temperature, so that the electric constant temperature water bath with stirring structure has the functions of stable support, reliable fixation, uniform stirring and constant temperature heating, which meets the needs of liquid heating and stirring in relevant experiments or production processes.

[0030] It is worth noting that the bottom openings of both the rotating shaft 12 and the stirring shaft 42 are square. The square cross-sections of the rotating shaft 12 and the bottom openings of the stirring shaft 42 ensure that the torque can be stably transmitted when they are inserted together, avoiding relative rotation and ensuring the effective transmission of stirring power.

[0031] Furthermore, the bottom of the side seat 20 is mounted on both sides of the top surface of the base 10 via connecting feet 21, so that the side seat 20 is firmly connected to the base 10, providing a stable support structure for the subsequent installation of components such as the clamping cylinder 30.

[0032] Specifically, the clamping cylinder 30 is connected to the outer wall of the side seat 20. The piston rod 32 of the clamping cylinder 30 passes through the side seat 20 and is coaxially connected to the clamping plate 31. Through the clamping cylinder 30, piston rod 32 and clamping plate 31, when the clamping cylinder 30 is working, the piston rod 32 can drive the clamping plate 31 to move, thereby clamping or releasing the water bath body 40, which facilitates the installation and disassembly of the equipment.

[0033] Among them, the surface of the clamping plate 31 that contacts the water bath body 40 is provided with several uniformly spaced anti-slip protrusions 33. The anti-slip protrusions 33 are made of silicone and the height of the protrusions is 1-3mm. The silicone anti-slip protrusions 33 increase the friction when the clamping plate 31 contacts the water bath body 40, preventing the water bath body 40 from shifting after clamping. At the same time, the silicone material has a certain elasticity and will not damage the outer wall of the water bath body 40.

[0034] In addition, an insulating shell 41 is provided on the outer wall of the water bath body 40. The insulating shell 41 reduces the heat loss inside the water bath body 40, improves energy efficiency, and maintains a stable internal temperature.

[0035] Working principle of this electric thermostatic water bath with stirring structure:

[0036] First, place the water bath body 40 on the base 10 and fix it using the clamping cylinders 30 on the two side seats 20; start the clamping cylinders 30, and its piston rod 32 extends, driving the clamping plate 31 to move until the anti-slip protrusions 33 on the clamping plate 31 are in close contact with the outer wall of the water bath body 40 and fix the equipment.

[0037] Next, the liquid that needs to be heated and stirred is added into the water bath body 40; then, the power supply to the servo stirring motor 11 and the constant temperature heating rod 43 is turned on; the constant temperature heating rod 43 uses a PTC heating ceramic tube to start heating the liquid at a constant temperature; at the same time, the rotating shaft 12 of the servo stirring motor 11 drives the stirring shaft 42 to rotate, and the stirring blades 45 on the stirring shaft 42 rotate accordingly to stir the liquid, making the liquid heat more evenly; since the bottom of the stirring shaft 42 is fixed to the center of the bottom of the water bath body 40 through a sealed bearing 44, it is ensured that the liquid will not leak;

[0038] During use, the heat-insulating outer shell 41 can reduce heat loss and maintain a stable temperature. After use, first turn off the power to the servo stirring motor 11 and the constant temperature heating rod 43. After the liquid cools down, start the clamping cylinder 30 to retract its piston rod 32, release the clamping plate 31, and then take out the water bath body 40 for subsequent processing.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
