Description

Technical Field

[0001] This utility model relates to the field of experimental equipment technology, specifically a water bath heating device suitable for centrifuge tubes. Background Technology

[0002] Centrifuge tubes are tubular sample containers, which can be sealed with caps or compression caps, and are common laboratory supplies. When heating centrifuge tubes during experiments, direct heating over a flame can cause uneven heating, potentially leading to liquid splashing out or even the tube bursting. Water bath heating provides a stable and uniform heating environment, avoiding these risks. It also ensures that the sample in the centrifuge tube is heated evenly, preventing localized overheating or underheating, thus improving the accuracy and reliability of experimental results. Therefore, water bath heating is a commonly used and effective method.

[0003] Patent CN221536739U discloses a water bath suitable for centrifuge tubes of various aperture sizes. The device includes a water bath body, a lid, and a centrifuge tube support. The support has multiple centrifuge tube placement holes, each containing a centrifuge tube fixing sleeve. A first through-hole is formed at the center of the fixing sleeve. A turntable is rotatably connected inside the fixing sleeve, with a second through-hole at its center. The first and second through-holes are coaxial and their diameters are less than or equal to that of the second through-hole. Multiple sliders are slidably connected to the turntable, each slider including a clamping part and a sliding part. These sliders slide together along the turntable via their respective sliding parts and cooperate with each other through their clamping parts to control the size of the exposed aperture of the second through-hole. This device can simultaneously heat centrifuge tubes of different sizes in a water bath, improving experimental efficiency and ensuring the accuracy of experimental results.

[0004] Although the above-mentioned device can be applied to centrifuge tubes of different sizes, it still has the following shortcomings:

[0005] The aforementioned device clamps centrifuge tubes of different diameters by controlling the clamping and sliding parts, but it does not take into account the fact that centrifuge tubes of different specifications also have different lengths and shapes. For example, 50ml flat-bottom centrifuge tubes and 5ml conical-bottom centrifuge tubes have different shapes, diameters, and lengths, and cannot be clamped together. They need to be adjusted in batches for water bath heating, thus limiting their applicability to a certain range. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a water bath heating device suitable for centrifuge tubes, which can perform water bath heating on centrifuge tubes of different lengths, diameters, and shapes.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a water bath heating device suitable for centrifuge tubes, comprising a water bath heating box body, a top cover provided on the water bath heating box body, a heat spreader provided on the bottom surface inside the water bath heating box body, several movable components provided on both sides inside the water bath heating box body, clamping components provided on the movable components, a water inlet provided on the upper end of one side of the water bath heating box body, a water outlet provided on the lower end of the same side as the water inlet, and the upper end of the clamping components and the lower end of the movable components are both higher than the water inlet.

[0008] Furthermore, the clamping assembly includes symmetrically arranged arc-shaped clamps, one end of which is provided with a fixing screw for movement, and the other end of which is provided with a limit rod.

[0010] Furthermore, the limiting frame is telescopic, and a sliding groove for telescopic movement is provided inside the limiting frame. A spring is provided inside the sliding groove, and a sponge pad is provided on the inner side of the bottom surface of the limiting frame.

[0011] Furthermore, propulsion fan blades are installed on the inner walls of both sides of the main body of the water bath heating tank.

[0012] Furthermore, water level observation windows are provided on both sides of the main body of the water bath heating tank.

[0013] Furthermore, the water level observation window is equipped with graduations.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] By incorporating arc-shaped clamps, centrifuge tubes of various types and sizes can be held. A movable component on the clamping assembly allows for vertical movement of centrifuge tubes of different lengths to reach the appropriate height, preventing uneven heating. A telescopic limiting frame allows for the retractable placement of longer centrifuge tubes, further expanding its applicability and ensuring effective water bath treatment.

Propulsion fan blades on the inner walls of both sides of the water bath heating chamber circulate the water, ensuring uniform temperature throughout and consistent heating. Water level observation windows with graduations on both sides of the heating chamber allow operators to monitor the water level and react promptly. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] like Figures 1 to 4As shown, a water bath heating device suitable for centrifuge tubes includes a water bath heating box body 1, a top cover 2 on the water bath heating box body 1, a heat spreader 5 on the bottom surface inside the water bath heating box body 1, a plurality of moving components 3 on both sides inside the water bath heating box body 1, clamping components 4 on the moving components 3, a water inlet 101 on the upper end of one side of the water bath heating box body 1, a water outlet 102 on the lower end of the same side of the water inlet 101, and the upper end of the clamping component 4 and the lower end of the moving component 3 are both higher than the water inlet 101.

[0023] like Figure 1 As shown, the water bath heating device in this utility model is structurally similar to existing water bath heating devices. For example, patent CN221536739U discloses a water bath suitable for centrifuge tubes of various aperture specifications. The main improvement of this utility model is that it can perform water bath heating on centrifuge tubes of different lengths, diameters, and shapes. Figures 1 to 4 As shown, the water bath heating device for centrifuge tubes in this utility model, when water bath heating of centrifuge tubes is required, firstly, cold water is added from the inlet 101 according to the type of centrifuge tube, and the water volume is observed through the water volume observation window 106. When the water volume is appropriate, the addition is stopped, and the heat spreader 5 is controlled to heat the water. During the heating process, the pusher fan blade 105 will rotate to make the temperature uniform throughout the main body 1 of the water bath heating box. Then, the top cover 2 is removed, and the drive motor 302 is controlled to rotate the lead screw 301, so that the clamping assembly 4 rises to the placement plate 104. Then, the fixing screw 402 is loosened, and the arc-shaped clamp 401 at the far end will move outward. When the distance between the arc-shaped clamps 401 is greater than the diameter of the centrifuge tube, the centrifuge tube is placed in. When dealing with longer centrifuge tubes, the spring 408 is placed in the sliding groove 407. The telescopic mechanism extends the telescopic end of the limiting frame 404, allowing centrifuge tubes to be placed. Simultaneously, the sponge pad 409 on the bottom of the limiting frame 404 protects the centrifuge tubes, reducing the rebound force after telescopic extension. The fixing screw 402 is then tightened to secure the centrifuge tubes within the arc-shaped clamp 401. During this process, the buffer pad 405 alleviates the pressure from the clamping, protecting the centrifuge tubes. After clamping the centrifuge tubes, the drive motor 302 is controlled to rotate the lead screw 301, moving the clamping assembly 4 downwards to a suitable height, immersing the portion of the centrifuge tube requiring water bath heating in the water. Once heating is complete, the drive motor 302 is controlled again to lift the clamping assembly 4, and the fixing screw 402 is loosened to remove the centrifuge tubes, completing the water bath heating process.

[0024] like Figure 2 and Figure 4As shown, the clamping assembly 4 includes symmetrically arranged arc-shaped clamps 401. One end of the arc-shaped clamp 401 is provided with a fixing screw 402 for clamp movement, and the other end of the arc-shaped clamp 401 is provided with a limit rod 406. A moving plate 403 is provided on the arc-shaped clamp 401 located inside the water bath heating box body 1. A moving assembly 3 is provided on the moving plate 403. A limit frame 404 is provided at the lower end of the arc-shaped clamp 401. A buffer pad 405 is provided inside the arc-shaped clamp 401. A moving groove 103 is provided on the inner wall of the water bath heating box body 1 for the moving plate 403 to move up and down. The moving groove 103 is higher than the water inlet 101.

[0025] like Figure 2 and Figure 4 As shown, the moving component 3 includes a lead screw 301 rotatably mounted on the moving plate 403, a drive motor 302 is mounted at the top of the lead screw 301, a placement plate 104 for placing the drive motor 302 is mounted at the upper end of the water bath heating box body 1, a closed motor housing 303 is mounted outside the drive motor 302, and a limiting groove 201 for fitting the closed motor housing 303 is opened on the inner side of the top cover 2.

[0026] Specifically, when the centrifuge tube needs to be heated, the drive motor 302 is controlled to rotate the lead screw 301, causing the clamping assembly 4 to rise to the placement plate 104. Then, the fixing screw 402 is loosened, and the far-end arc-shaped clamp 401 will move outward. When the distance between the arc-shaped clamps 401 is greater than the diameter of the centrifuge tube, the centrifuge tube is placed in, and the fixing screw 402 is tightened again, so that the centrifuge tube is fixed in the arc-shaped clamp 401. During the fixing process, the buffer pad 405 will relieve the pressure brought by the clamping and protect the centrifuge tube. Then, the drive motor 302 is controlled to rotate the lead screw 301, moving the clamping assembly 4 downward. After it is moved to a suitable height, the drive motor 302 is stopped, so that the part of the centrifuge tube that needs to be heated in the water bath is immersed in water to complete the water bath heating of the centrifuge tube. Among them, the moving tank 103 is higher than the water inlet 101, and the arc-shaped clamp 401 is also higher than the water inlet 101, so as to prevent the water level of the hot water from being higher than the centrifuge tube.

[0027] like Figure 4 As shown, the limiting frame 404 is telescopic, and a sliding groove 407 for telescopic extension is provided inside the limiting frame 404. A spring 408 is provided inside the sliding groove 407, and a sponge pad layer 409 is provided on the inner side of the bottom surface of the limiting frame 404.

[0028] Specifically, by setting up a retractable limiting frame 404, when facing longer centrifuge tubes, as the spring 408 extends and retracts within the sliding groove 407, the retractable end of the limiting frame 404 will be extended, thereby accommodating more types of centrifuge tubes and ensuring the water bath effect of these centrifuge tubes. At the same time, the sponge pad 409 set on the bottom surface of the limiting frame 404 can protect these centrifuge tubes and reduce the rebound force on the centrifuge tubes after extension and retraction.

[0029] like Figure 3 As shown, the inner walls on both sides of the main body 1 of the water bath heating box are equipped with pusher blades 105. This arrangement can push the water in the water tank to flow, thereby delivering the water heated by the heat spreader 5 to all parts, so that the water temperature is consistent everywhere and the uniformity of water bath heating is guaranteed.

[0030] like Figure 2 and Figure 3 As shown, water volume observation windows 106 are provided in the middle of both sides of the main body 1 of the water bath heating box, and scales 107 are provided on the water volume observation windows 106.

[0031] Specifically, by setting up a water level observation window 106, the operator can observe the water level in the heating tank, and with the help of the scale 107 set on the water level observation window 106, they can react in a timely manner.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
