Description

Technical Field

[0001] This utility model relates to the field of laboratory apparatus cleaning technology, specifically a cleaning device for laboratory conical flasks. Background Technology

[0002] Erlenmeyer flasks, as an indispensable and commonly used glass instrument in the laboratory, are made of hard glass and have a regular triangular shape in their longitudinal section. This design is not only aesthetically pleasing but also practical, making them ideal containers for experimental operations such as titration reactions. In order to make the experimental results more accurate and reliable, Erlenmeyer flasks are usually equipped with special cleaning devices to clean them.

[0003] The patent with publication number CN215466866U discloses a conical flask cleaning device for salt and iodine laboratory use, including a base with a water collection chamber inside. A drain pipe is installed on one side of the base, and a drain valve is fitted onto the drain pipe. A water storage tank is installed on one side of the top of the base, and a main cleaning water supply pipe is provided at the bottom of the water storage tank. The main body of the cleaning device is located on the top of the base and close to the water storage tank. The main body of the cleaning device has a cleaning chamber and a drying chamber arranged from left to right inside. Both the cleaning chamber and the drying chamber have doors installed on the front edge of their base surfaces.

[0004] The aforementioned device still has the following drawbacks: The cleaning rack of the laboratory conical flask cleaning device is usually equipped with multiple vertically downward spray pipes. The conical flasks are directly inserted upside down into these spray pipes for fixation. During cleaning, the top rotating sprayer sprays water synchronously with the vertical spray pipes to rinse the inside and outside of the flasks. Although the spray system itself has a certain positioning and limiting ability, the impact of the water flow can cause the conical flasks to shift or shake. Without additional limiting measures, adjacent conical flasks may collide during vibration. Although laboratory glassware has a certain impact resistance, long-term high-frequency collisions will still cause wear, cracks or even breakage of the flasks, ultimately shortening the service life of the equipment. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a cleaning device for laboratory conical flasks, which facilitates the limiting and prevention of movement and displacement of the conical flasks.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cleaning device for laboratory conical flasks, comprising a cleaning machine, a door connected to the cleaning machine, a cleaning rack connected inside the cleaning machine, and a spray pipe connected to the cleaning rack. An installation block is fixed to the outer wall of the spray pipe, and multiple limiting rods are installed on the installation block.

[0007] Furthermore, the mounting block is truncated cone-shaped, and an elastic silicone sleeve is mounted on the inclined surface of the mounting block.

[0008] Furthermore, an L-shaped blocking rod is fixedly connected to the top end of the limiting rod.

[0009] Furthermore, the outer walls of the L-shaped blocking rod and the limiting rod are both covered with elastic sponge, and the L-shaped blocking rod, the limiting rod and the elastic sponge on their outer walls are non-contact limiting devices with the conical bottle.

[0010] Furthermore, the inner corner surface of the L-shaped blocking rod is provided with a rounded transition.

[0011] Furthermore, multiple sets of mounting plates are installed on the inclined surface of the mounting block. Each set of mounting plates has a rotating groove of the same size on its opposite surface. Each set of rotating grooves is rotatably connected to the same rotating shaft. The rotating shaft passes through the lower end of the limiting rod and is fixedly connected. A first spring is fixedly connected to the surface of one of the mounting plates in each set at the end connected to the rotating shaft. The other end of the first spring is fixedly connected to the side wall of the limiting rod. A second spring is fixedly connected to the surface of the other mounting plate in each set at the end connected to the rotating shaft. The other end of the second spring is fixedly connected to the other side wall of the limiting rod.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model, through the cooperation of the mounting block and multiple limiting rods, can restrict the conical bottle within the limiting area enclosed by the multiple limiting rods. This restricts the horizontal movement of the conical bottle (front, back, left, and right), reduces its disorderly shaking under external force disturbance, thereby reducing the risk of bottle wear, cracks or breakage caused by external force, and extending the service life of the conical bottle. The structure is simple, easy to operate, and highly practical.

[0014] 2. This utility model, through the cooperation of the limiting rod and the L-shaped blocking rod, not only restricts the conical flask in front, back, left and right, but also restricts the conical flask in the top and bottom, so that the conical flask will not be washed onto the inner wall of the upper end of the cleaning machine by the water flow of the spray pipe, causing damage. This improves the structural stability of precision glassware in the automated cleaning process and extends the service life of high-value consumables in the laboratory.

[0015] 3. This utility model utilizes the cooperation of a rotating groove, a rotating shaft, a first spring, and a second spring. The rotating shaft drives the limiting rod to open and close along the trajectory of the rotating groove. With the bidirectional tension compensation of the first and second springs, the enclosure density of the limiting area in the horizontal direction can be adjusted, thereby adapting to conical flasks of different diameters and sizes. This achieves the compatible fixation of multiple specifications of vessels with a single clamp, taking into account both the flexibility of the experimental scenario and the utilization rate of the equipment.

[0020] 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.

[0021] like Figures 1 to 7 As shown, a cleaning device for laboratory conical flasks includes a cleaning machine 1, a door 2 connected to the cleaning machine 1, a cleaning rack 3 connected inside the cleaning machine 1, and a spray pipe 4 connected to the cleaning rack 3. An installation block 5 is fixed to the outer wall of the spray pipe 4, and multiple limiting rods 11 are installed on the installation block 5.

[0022] like Figure 1 As shown, the cleaning device for laboratory conical flasks in this utility model is structurally similar to existing cleaning devices for conical flasks used in salt and iodine laboratories. For example, patent publication number CN215466866U discloses a cleaning device for conical flasks used in salt and iodine laboratories. The main improvement of this utility model is that it facilitates the limiting and preventing movement and displacement of the conical flask. Figures 1 to 7 As shown, the laboratory conical flask cleaning device of this utility model allows the conical flask to be placed within a limiting area enclosed by multiple limiting rods 11 during use. This area is formed by multiple limiting rods 11 arranged in a ring array in the horizontal direction to form a ring-shaped protective matrix, thereby enclosing the limiting area. Through multi-point contact, the lateral displacement of the conical flask is constrained, reducing lateral displacement and disorderly shaking caused by equipment vibration or water flow disturbance. This reduces the risk of flask wear, cracks or breakage caused by collisions and extends the service life of the conical flask.

[0023] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, mounting block 5 is a frustum, and an elastic silicone sleeve is installed on its inclined surface. Specifically, the frustum design forms a hyperboloid conformal contact with the arcuate contour of the conical bottle mouth. Compared to a flat base, this increases the contact area, reducing pressure per unit area and preventing localized stress concentration at the bottle mouth. Furthermore, when the conical bottle experiences slight displacement due to external forces or equipment vibration, the inclined surface of the frustum automatically guides the bottle back to its center position through angle changes, providing stronger dynamic balance than a flat base. In addition, the elastic silicone sleeve provides cushioning and anti-slip properties; furthermore, its softness reduces the risk of damage to the conical bottle. Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, an L-shaped blocking rod 12 is fixed to the top of the limiting rod 11. Specifically, while restricting the conical flask in all directions, the L-shaped blocking rod 12 prevents the conical flask from moving upwards, thus limiting its vertical position. This prevents the conical flask from being washed onto the upper inner wall of the cleaning machine 1 by the water flow from the spray pipe 4, which would cause damage. This improves the structural stability of precision glassware during automated cleaning and extends the service life of high-value laboratory consumables.

[0024] like Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, the outer walls of both the L-shaped blocking rod 12 and the limiting rod 11 are covered with elastic sponges. The L-shaped blocking rod 12, the limiting rod 11, and the elastic sponges on their outer walls are positioned for non-contact limiting with the conical flask. Specifically, the elastic sponges reduce friction between the conical flask and the L-shaped blocking rod 12 and the limiting rod 11. Their softness also protects the conical flask from damage to its surface. Furthermore, the small gaps between the L-shaped blocking rod 12, the limiting rod 11, and the elastic sponges on their outer walls and the conical flask achieve non-contact limiting, allowing the conical flask and the L-shaped blocking rod 12 and the limiting rod 11 to be positioned without compromising their blocking function and without hindering the cleaning of the bottom of the conical flask.

[0025] like Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, the inner corner surface of the L-shaped blocking rod 12 is designed with a rounded transition. Specifically, through the rounded transition surface, a biomimetic curved surface structure can replace the traditional right-angled edges, forming a flexible contact interface and reducing the damage caused when the conical bottle comes into contact with the L-shaped blocking rod 12 and the limiting rod 11.

[0026] like Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, multiple sets of mounting plates 6 are installed on the inclined surface of the mounting block 5. Each set of mounting plates 6 has a rotating groove 7 of the same size on its opposite side. Each set of rotating grooves 7 is rotatably connected to the same rotating shaft 8. The rotating shaft 8 passes through the lower end of the limiting rod 11 and is fixedly connected. A first spring 9 is fixedly connected to the surface of one of the mounting plates 6 in each set at the end connected to the rotating shaft 8. The other end of the first spring 9 is fixedly connected to the side wall of the limiting rod 11. A second spring 10 is fixedly connected to the surface of the other mounting plate 6 in each set at the end connected to the rotating shaft 8. The other end of the second spring 10 is fixedly connected to the other side wall of the limiting rod 11. Specifically, when the conical flask is placed into the restricted area enclosed by multiple L-shaped blocking rods 12 and multiple limiting rods 11, it does not need to be moved. When the conical flask is lowered, the L-shaped blocking rods 12 and the limiting rods 11 will open and close along the trajectory of the rotating groove 7 under the bidirectional tension compensation of the first spring 9 and the second spring 10, making it easy and simple to open and put in. At the same time, the limiting rods 11 and the L-shaped blocking rods 12 are driven to open and close along the trajectory of the rotating groove 7 by the rotating shaft 8, which can adjust the enclosure density of the limiting area in the horizontal direction, thereby adapting to conical flasks of different diameters and sizes, realizing the compatible fixation of multiple specifications of vessels by a single clamp, and taking into account the flexibility of the experimental scenario and the utilization rate of the equipment.

[0027] 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.
