Description

Technical Field

[0001] This utility model relates to the field of laboratory constant temperature equipment technology, specifically a modular inner liner for high and low temperature constant temperature water baths that is easy to clean and maintain. Background Technology

[0002] High and low temperature constant temperature water baths are commonly used equipment in laboratories to provide a constant temperature environment. Their core component is the inner liner that holds the heat-conducting medium and experimental samples. Currently, most water baths have an inner liner that is fixedly connected to the main body, or, although removable, is very bulky and inconvenient. This traditional structure has significant drawbacks:

[0003] (1) Cleaning and maintenance are extremely inconvenient: Bacteria or residual contaminants can easily grow in the corners, bottom and side wall welds of the inner liner. When cleaning, the operator has to bend over and probe into the inside of the chamber to wipe it, which is not only difficult to operate, but also very easy to leave cleaning dead corners, resulting in cross-contamination between different batches of experiments, which poses a serious threat to the accuracy of experimental results.

[0004] (2) Poor versatility and interchangeability: The fixed inner tank is bound to a specific model of water bath, and once damaged, the replacement cost is high and the cycle is long. Users also cannot quickly replace it according to experimental needs (such as the need for an inner tank of different materials or special coatings).

[0005] (3) Safety hazards exist: During cleaning or replacement, there is a risk of dropping and breaking the heavy and smooth inner liner when handling it, and the sharp edges of the fixed inner liner can easily scratch the operator during cleaning. Therefore, there is an urgent need for an improved inner liner structure that can solve the above problems. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a modular inner liner for a high and low temperature constant temperature water bath that has a reasonable structure and is easy to disassemble, clean and maintain. The technical solution adopted by this utility model to solve its technical problem is as follows: a modular inner liner for a high and low temperature constant temperature water bath, which is installed inside the water bath. The bottom of the inner liner is supported on a guide rail at the bottom of the water bath by a support frame with pulleys. The side wall of the inner liner is provided with a circumferential overflow recovery assembly for collecting and guiding overflowing liquid. The circumferential overflow recovery assembly includes a first overflow recovery trough disposed on the left and right side walls of the inner liner and rotatably connected to the front end of the inner liner, and a second overflow recovery trough fixedly disposed on the front side wall of the inner liner and higher than the first overflow recovery trough. The two ends of the second overflow recovery trough are connected to the front end of the corresponding first overflow recovery trough through a downward curved flow guiding structure. An elastic support assembly is provided on the inner liner below the middle of the first overflow recovery trough. The elastic support assembly includes a spring support block installed on the inner liner, and the upper end of the spring support block is provided with a spring abutting against the bottom of the first overflow recovery trough.

[0007] Furthermore, the inner liner is provided with a push handle on its side wall.

[0008] Furthermore, the first overflow recovery tank is rotatably connected to the vertical mounting plate on the front side wall of the inner liner via a rotating shaft. The first overflow recovery tank remains horizontal in its natural state, and when subjected to downward pressure, the tank body rotates and tilts around its front rotating shaft, thereby draining the accumulated liquid.

[0009] Furthermore, a flow guide hose is connected to the rear end of the first overflow recovery tank.

[0010] Furthermore, the pulley is a universal wheel with a braking device.

[0011] The beneficial effects of this utility model are:

[0012] 1. The inner tank, with its pulley and guide rail design, can be easily pulled out of the water bath like a drawer and moved to the sink for thorough rinsing, eliminating cleaning dead corners and fundamentally preventing cross-contamination, thus achieving true modularity.

[0013] 2. The support frame and pulleys form a stable mobile base. Combined with the push handle on the side wall, operators do not need to directly hold the smooth and heavy inner liner, which greatly reduces the risk of damage and personal injury.

[0014] 3. The unique surround overflow recovery assembly, especially its tiltable drainage design, can efficiently collect and guide overflow liquid to a designated container, avoiding media contamination and waste.

[0015] 4. This modular inner liner can be used as a standard accessory to adapt to various main unit models. Users can prepare multiple inner liners as needed for quick switching, reducing long-term usage costs and downtime. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] like Figure 1 and Figure 2 The present invention provides a modular inner liner for a high and low temperature constant temperature water bath, the core of which is an independently movable inner liner module. The inner liner 3 is preferably made of stainless steel by stamping, possessing good thermal conductivity and corrosion resistance. Its bottom is fastened to a support frame 4 by screws. This support frame 4 not only enhances the structural strength of the inner liner, but also has casters 5 with brakes installed at its bottom. Correspondingly, a guide rail 2 is provided at the bottom of the water bath 1. Through the cooperation of the casters 5 and the guide rail 2, the inner liner 3 can be easily pulled out or pushed into the main unit of the water bath 1 like a drawer, achieving true modularity. For easy pushing and pulling operation, push handles 6 are provided on both the front and rear side walls of the inner liner 3.

[0022] Another core innovation of this utility model lies in the surrounding overflow recovery assembly. This assembly includes a first overflow recovery trough 7 disposed on the left and right side walls of the inner liner 3 and a second overflow recovery trough 8 disposed on the front side wall. The front end of the first overflow recovery trough 7 is rotatably connected to a vertical mounting plate 10 on the front side wall of the inner liner via a pivot 9. Below the center of the trough, an elastic support assembly 11 is provided, consisting of a spring support block 14 fixed to the side wall of the inner liner and a spring 15 mounted thereon. The upper end of the spring 15 always abuts against the bottom of the first overflow recovery trough 7, keeping it horizontal in its natural state. The second overflow recovery trough 8 is positioned higher than the first overflow recovery trough 7, and its two ends smoothly connect to the front ends of the first overflow recovery troughs 7 on the left and right sides via a downward-curved arc-shaped flow guide structure 12. This design ensures that liquid overflowing from the front end of the inner liner is collected and ultimately flows into the first overflow recovery trough 7.

[0023] A guide hose 13 is connected to the rear end of the first overflow recovery tank 7. When drainage is needed, the operator simply presses the first overflow recovery tank 7 downwards by hand. The tank body will overcome the elastic force of the spring 15 and rotate around the front pivot 9, tilting the tank so that the accumulated liquid is drained into the designated collection container through the guide hose 13 under the action of gravity. After releasing the hand, the first overflow recovery tank 7 automatically returns to a horizontal state under the reset action of the spring 15, waiting for the next collection of overflow liquid.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
