Description

Technical Field

[0001] The utility model relates to the technical field of concentrators, in particular to a vacuum parallel concentrator with an easy-to-open upper cover. Background Art

[0002] The vacuum parallel concentrator is a relatively common vacuum concentration device, mainly used for sample concentration. The vacuum parallel concentrator places multiple sample bottles containing samples in a hot water bath. The samples are heated in the hot water bath. Driven by the oscillation mechanism, the samples in the hot water bath produce vortex oscillations, increasing the sample surface area and accelerating evaporation. At the same time, under the action of the vacuum pump, the samples in the sample bottles are placed in a negative pressure environment, further improving the sample evaporation and concentration speed. Therefore, the vacuum parallel concentrator is a high-efficiency vacuum concentration device with heating, oscillation and decompression functions.

[0003] The sample bottles are heated by hot water in a water bath, but during the oscillation process, hot water easily seeps out from the gap between the holes of the sample rack and the sample bottles, affecting the normal use of the concentrator;

[0004] An existing patent (publication number: CN219167718U) discloses a parallel vacuum concentrator. This utility model uses a movable frame to set a sealing mechanism at the tube holes of the fixed frame and the movable frame, so that the flexible sealing sleeve fits tightly against the tube wall of the sample tube under the pressure of the ring. This can not only prevent hot water in the water bath from leaking out, but also reduce the collision between the sample tube and the sample rack, thereby protecting the sample tube.

[0005] In response to the above problems, existing patents have provided solutions. However, in the above patents, the sealing cover plate needs to be manually opened and closed by the user when used to seal the hot water bath module and the sample tube placed inside the hot water bath module. However, due to different user operating techniques and strengths, the position and compression degree of the sealing cover plate may be inconsistent each time it is closed, resulting in poor sealing effect. Moreover, the manual opening and closing method not only brings a bad user experience, but also makes it inconvenient for the user to operate in actual use.

[0006] Therefore, a vacuum parallel concentrator with an easy-to-open upper cover is proposed. Utility Model Content

[0007] The purpose of the present utility model is to provide a vacuum parallel concentrator with an easy-to-open upper cover, which can solve the problem in the above-mentioned patent that the sealing cover needs to be manually closed and opened by the user when used to seal the hot water bath module and the sample tube placed inside the hot water bath module. Due to different user operating techniques and strengths, the position and compression degree of the sealing cover may be inconsistent each time it is closed, resulting in poor sealing effect. In addition, the manual opening and closing method not only brings a bad user experience, but also makes it inconvenient for the user to operate in actual use.

[0009] The automatic lid opening mechanism includes a bracket bolted to the rear side of the top of the hot water bath module, a fixing sleeve bolted to the bottom side of the bracket, an electric push rod rotatably connected to the inside of the fixing sleeve, a rotating rod rotatably connected to the top side of the bracket, the rear side of the rotating rod rotatably connected to the telescopic end of the electric push rod, a connecting block bolted to the bottom of the rotating rod, and the bottom of the connecting block bolted to the top of the cover plate.

[0011] Preferably, an electromagnet is provided inside the placement box, and the electromagnet is electrically connected to the controller.

[0012] Preferably, an iron sheet is bolted to the front side of the bottom of the cover plate, and the iron sheet is electrically connected to the electromagnet.

[0013] Preferably, both sides of the rear side of the top of the oscillation module are bolted with limiting rods, and the limiting rods are L-shaped.

[0014] Preferably, a buffer pad is bonded to the front side of the limiting rod, and the buffer pad is made of rubber material.

[0015] Preferably, a stop pad is bonded to the bottom of the cover plate, and the stop pad is located on the top of the hot water bath module.

[0016] Preferably, a pipe blocking pad is fixedly connected to the bottom of the blocking pad, and the pipe blocking pad is located on the top of the hot water bath module.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. This application realizes automatic opening and closing of the cover by setting an automatic opening and closing mechanism, avoiding the problem of poor sealing effect caused by manual operation techniques and strength differences of the user. The electric push rod accurately controls the rotation of the rotating rod, thereby driving the cover to open and close stably, ensuring that the position and compression degree are consistent each time it is closed, effectively protecting the sealing environment of the hot water bath module and its internal sample tubes, improving the accuracy and stability of the experiment, greatly improving the convenience of operation, and reducing the labor intensity of the user. Especially when processing multiple samples, the automatic opening and closing function saves operation time, improves work efficiency, optimizes the overall user experience, and makes the equipment operation more in line with the efficiency and precision requirements of modern laboratories;

[0019] 2. This application further enhances the sealing of the cover when it is closed by setting a magnetic suction component, ensuring the stability of the heat, water vapor and vacuum environment in the hot water bath module, reducing heat loss and external interference, which is conducive to the stable progress of the sample concentration process and improving the reliability of the experimental results. At the same time, the automatic opening mechanism is assisted to fix the cover, preventing the cover from being accidentally opened during the operation of the equipment, thereby ensuring the safety of the experiment.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1-6 , this utility model provides a technical solution:

[0029] A vacuum parallel concentrator with an easy-to-open upper cover comprises an oscillating module 1, a hot water bath module 2 is provided on the top of the oscillating module 1, a controller 3 is provided on the front side of the oscillating module 1, an automatic cover opening mechanism 4 is provided on the rear side of the top of the hot water bath module 2, a cover plate 5 is provided on the top of the hot water bath module 2, and a magnetic attraction component 6 is provided between the cover plate 5 and the hot water bath module 2;

[0030] The automatic lid opening mechanism 4 includes a bracket 401 bolted to the top rear side of the hot water bath module 2, a fixing sleeve 402 is bolted to the bottom side of the bracket 401, an electric push rod 403 is rotatably connected to the inside of the fixing sleeve 402, a rotating rod 404 is rotatably connected to the top side of the bracket 401, the rear side of the rotating rod 404 is rotatably connected to the telescopic end of the electric push rod 403, a connecting block 405 is bolted to the bottom of the rotating rod 404, and the bottom of the connecting block 405 is bolted to the top of the cover plate 5.

[0031] When the cover 5 needs to be opened, the user can use the controller 3 to send an instruction to the magnetic component 6 and the automatic cover opening mechanism 4, first cut off the power to the magnetic component 6, so that the cover 5 is disconnected from the magnetic connection with the hot water bath module 2, and at the same time, the electric push rod 403 begins to retract after receiving the signal, and the telescopic end of the electric push rod 403 pulls the rotating rod 404 upward. Since the rotating rod 404 is rotatably connected to the top of the bracket 401, the rotating rod 404 rotates with its connection point with the bracket 401 as the axis, and the connecting block 405 at the bottom of the rotating rod 404 moves upward with the rotation of the rotating rod 404. The connecting block 405 drives the cover 5 to lift up, thereby realizing the automatic opening of the cover 5. For example, during the experiment, when it is necessary to add or remove a sample tube from the hot water bath module 2, the user does not need to manually lift the cover 5 with effort, but only needs to operate the controller 3 to easily open the cover 5, which is convenient and quick. When the cover 5 needs to be closed, the controller 3 controls the electric push rod When the cover 5 is closed, the cover 5 is in a closed position, and the cover 5 is in a closed position, and the cover 5 is in a closed position, and the cover 5 is in a closed position, and the cover 5 is in a closed position, and the cover 5 is in a closed position, and the cover 5 is in a closed position, and the cover 5 is in a closed position, and the cover 5 is in a closed position, and the cover 5 is in a closed position, and the cover 5 is in a closed position, and the cover 5 is in a closed position, and the cover 5 is in a closed position, and the cover 5 is in a closed position, and the cover 5 is in a closed position, and the cover 5 is in a closed position, and the cover 5 is in a closed position, and the cover 5 is in a closed position, and the cover 5 is in a closed position, and the cover 5 is in a closed position, and the cover 5 is in a closed position, and the cover 5 is in a closed position, and the cover 5 is in a closed position, and the cover 5 is in a closed position, and the cover 5 is in a closed position, and the cover 5 is in a closed position, and the cover 5 is in a closed position, and the cover 5 is in a closed position, and the cover 5 is in a closed position, and the cover 5 is in a closed position, and the cover 5 is in a closed position, and the cover 5 is in a closed position, and the cover 5 is in a closed position, and the cover 5 is in a closed position, and the cover

[0032] Specifically, such as Figure 4 As shown, the magnetic attraction assembly 6 includes a placement box 601 bolted to the top front side of the hot water bath module 2, and the interior of the placement box 601 is a cavity.

[0033] Specifically, such as Figure 4 As shown, an electromagnet 602 is provided inside the placement box 601 , and the electromagnet 602 is electrically connected to the controller 3 .

[0034] Specifically, such as Figure 4 As shown, an iron sheet 603 is bolted to the front side of the bottom of the cover plate 5 , and the iron sheet 603 is electrically connected to the electromagnet 602 .

[0035] In this embodiment: through the electrical connection between the electromagnet 602 and the controller 3, the generation and disappearance of the magnetic force can be accurately controlled according to the instructions. When the cover 5 needs to be opened, the controller 3 controls the electromagnet 602 to cut off the power, so that the cover 5 can be smoothly separated from the adsorption of the hot water bath module 2, and the automatic opening operation is realized. When the cover 5 is closed, the electromagnet 602 is energized to generate magnetic force, which tightly adsorbs the iron sheet 603 at the bottom of the cover 5, ensuring that the cover 5 is tightly fitted with the hot water bath module 2, greatly improving the sealing effect, and effectively preventing the hot water, steam or vacuum environment in the hot water bath module 2 from leaking, ensuring the stability of the experimental environment, and facilitating the smooth progress of the experiment.

[0036] Specifically, such as Figure 5 As shown, both sides of the top rear side of the oscillation module 1 are bolted with limit rods 7, and the limit rods 7 are L-shaped.

[0037] Specifically, such as Figure 5 As shown, a buffer pad 8 is bonded to the front side of the limiting rod 7, and the buffer pad 8 is made of rubber material.

[0038] In this embodiment: by providing a limit rod 7 and a buffer pad 8, during the opening process of the cover 5, the limit rod 7 limits the maximum opening angle of the cover 5 to prevent the cover 5 from being over-opened and causing damage or affecting the surrounding environment of the equipment. At the same time, the buffer pad 8 on the front side of the limit rod 7 plays a buffering role when the cover 5 contacts the limit rod 7 to avoid damage to the cover 5 due to hard collision.

[0039] Specifically, such as Figure 6 As shown, a stopper 9 is bonded to the bottom of the cover plate 5 , and the stopper 9 is located on the top of the hot water bath module 2 .

[0040] Specifically, such as Figure 6 As shown, the bottom of the blocking pad 9 is fixedly connected to a pipe blocking pad 10 , and the pipe blocking pad 10 is located on the top of the hot water bath module 2 .

[0041] In this embodiment, the blocking gasket 9 at the bottom of the cover plate 5 cooperates with the pipe blocking gasket 10 to fill the top of the hot water bath module 2 when the cover plate 5 is closed, further enhancing the sealing effect and preventing gas or liquid leakage in the hot water bath module 2, thereby helping to maintain stable experimental conditions and improve the reliability of experimental results.

[0042] Working principle: During the use of the vacuum parallel concentrator, the user controls the electromagnet 602 and the electric push rod 403 respectively through the controller 3. When the cover 5 needs to be opened, the controller 3 controls the electromagnet 602 to be powered off, so that the electromagnet 602 and the iron sheet 603 are separated from the magnetic connection, thereby releasing the adsorption of the cover 5 and the hot water bath module 2. At the same time, the electric push rod 403 contracts, and the cover 5 is driven to rise steadily and automatically open through the rotating rod 404 and the connecting block 405. It is convenient to operate when taking and placing sample tubes in the experiment. When closing, the electric push rod 403 extends and pushes the rotating rod 404 to rotate in the opposite direction, accurately controlling the cover 5 to descend to fit tightly against the top of the hot water bath module 2. The position and angle are accurate and consistent to ensure a tight seal. When the cover is sealed and close to closing, the electromagnet 602 is energized to absorb the iron sheet 603 at the bottom of the cover 5, further enhancing the sealing, preventing internal hot water, steam or vacuum leakage, and ensuring the stability of the experimental environment. During this process, the limit rod 7 on the top rear side of the oscillation module 1 limits the maximum opening angle of the cover 5 to prevent excessive opening from damaging the equipment or affecting the environment. The front rubber buffer pad 8 cushions when the cover 5 contacts to avoid damage due to hard collision. The baffle 9 and the pipe blocking pad 10 at the bottom of the cover 5 fill the top of the hot water bath module 2 when closed, enhancing the seal, preventing gas or liquid leakage, maintaining stable experimental conditions, and improving the reliability of experimental results. The overall coordination improves the safety and stability of equipment operation and the accuracy and convenience of the experiment.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
