[0021] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model, and are not used to limit the present utility model.

[0022] To solve the technical problem that it is time-consuming and laborious to replace the card seat, the utility model provides a vacuum concentrator that can be applicable to storage dishes of different sizes.

[0023] It should be noted that the vacuum concentrator described in the utility model is used for but not limited to DNA sample storage dishes, etc. For the convenience of description, in the utility model, only a vacuum concentrator applied to DNA sample storage dishes is taken as an example for description, and the principle of a vacuum concentrator applied to other types of equipment is substantially the same as that applied to DNA sample storage dishes, and will not be elaborated one by one here.

[0024] Please refer to Figure 1 - Figure 3 where Figure 1 is a schematic structural diagram of a vacuum concentrator in an embodiment of the utility model. A vacuum concentrator includes a box body 1, clamping claws 2 and a driving member 3. The box body 1 has a cavity 11 with an upward opening. The number of clamping claws 2 is two, and the two clamping claws 2 are arranged facing each other. The opposite sides of the two clamping claws 2 are arranged in a staggered layer; and the number of driving members 3 is two. The two driving members 3 are respectively arranged along the opposite sides of the two clamping claws 2. The two driving members 3 are used to drive the two clamping claws 2 to move towards each other until the two clamping claws 2 are interlaced with each other and form different accommodating cavities 4.

[0025] In this embodiment, through the arrangement of the clamping claws 2, a clamping mechanism for the storage dish is formed. Further, due to the staggered layer arrangement of the opposite sides of the two clamping claws 2, the two clamping claws 2 can clamp storage dishes of different sizes, so that when the device experiments with storage dishes of different sizes, there is no need to replace the card seat, which saves time and effort.

[0026] First, place the storage dish between the two clamping claws 2; then, start the driving member 3, and the two clamping claws 2 move towards each other until the two clamping claws 2 clamp the opposite sides of the storage dish. At the same time, according to the size of the storage dish, the degree of interpenetration between the two clamping claws 2 is different, that is, the storage dish is placed; finally, start the experiment.

[0027] Furthermore, in order for the two clamping claws 2 to better match the storage dish, both clamping claws 2 are arc-shaped.

[0028] Furthermore, two mounting plates 12 are fixedly connected to the opposite inner walls in the box body 1. The fixed ends of the two driving members 3 are respectively fixedly connected to the two mounting plates 12. The driving member 3 adopts an electric telescopic rod. The function of the mounting plate 12 is to facilitate the fixed connection between the fixed end of the electric telescopic rod and the inner wall of the box body 1. The movable ends of the two electric telescopic rods are arranged opposite to each other.

[0029] In one of the embodiments, please refer to Figure 2 and Figure 3, the jaw 2 includes a plurality of first jaws 21 and a plurality of second jaws 22. The first jaws 21 are longitudinally equally spaced, and the second jaws 22 are transversely equally spaced.

[0030] In this embodiment, the setting of the second jaw 22 enables the first jaw 21 to be placed on the second jaw 22 first before clamping the storage dish, so that the storage dish is suspended and waits to be clamped and fixed. There is no need for the experimenter to manually suspend the storage dish and wait for clamping, which reduces the operation intensity. At the same time, the driving member 3 is used to drive the two jaws 2 to move towards each other until the first jaw 21 clamps the storage dish, thus completing the fixation of the storage dish.

[0031] In one embodiment, please refer to Figure 2 , a pair of limit seats 13 are fixedly connected to the bottom surface inside the box body 1. The two limit seats 13 are arranged oppositely, and through holes 131 are opened in both limit seats 13. The movable ends of the two driving members 3 respectively penetrate through the two through holes 131 and are fixedly connected to the two jaws 2 respectively.

[0032] In this embodiment, the function of the limit seat 13 is to support the movable end of the electric telescopic rod, improve the stability of the electric telescopic rod, and prevent the electric telescopic rod from bending and deforming due to the gravity of the jaw 2, the storage dish or itself during long-term suspension.

[0033] In one embodiment, please refer to Figure 1 , a box cover 14 is rotatably connected to the top of the cavity 11.

[0034] In this embodiment, a sealing gasket is fixedly connected to the bottom surface of the box cover 14. The material of the sealing gasket is rubber. By providing the sealing gasket, the sealing performance of the device can be improved.

[0035] In one embodiment, please refer to Figure 1 , the box cover 14 is provided with an observation window 141.

[0036] In this embodiment, an observation window 141 is opened on the upper surface of the box cover 14. Through the opened observation window 141, the staff can easily understand the internal situation of the box body 1.

[0037] In one embodiment, please refer to Figure 1 , a temperature sensor 142 is installed on the observation window 141.

[0038] In this embodiment, through the temperature sensor 142, the temperature inside the box body 1 can be monitored in real time, avoiding the abnormal temperature inside the box body 1 caused by the abnormality of the temperature control system 16 not being detected in time.

[0039] In one embodiment, please refer to Figure 2, a vacuum pump 15 is installed on one side of the box body 1. The vacuum pump 15 is equipped with an air duct 151, and the air duct 151 communicates with the box body 1.

[0040] In this embodiment, the vacuum pump 15 can be started, and the inside of the box body 1 can be evacuated through the air duct 151 to form a negative pressure cavity. During operation, only the DNA sample storage dish needs to be placed inside the box body 1, and then the preparation can be carried out, which improves the work efficiency of the staff.

[0041] In one of the embodiments, please refer to Figure 1 , a temperature control system 16 is installed at the bottom of the box body 1.

[0042] In this embodiment, the temperature control system 16 can flexibly adjust the internal temperature of the box body 1. By precisely controlling the temperature, the experimental error caused by temperature changes can be reduced.

[0043] In one of the embodiments, please refer to Figure 1 - Figure 2 , a touch panel 17 is installed on one side of the box body 1. The touch panel 17 is electrically connected to the driving member 3, the vacuum pump 15 and the temperature control system 16 respectively.

[0044] In this embodiment, the touch panel 17 facilitates the staff to control the driving member 3, the vacuum pump 15 and the temperature control system 16.

[0045] In one of the embodiments, please refer to Figure 1 , a universal wheel 18 is fixedly connected to the bottom of the temperature control system 16.

[0046] In this embodiment, the function of the universal wheel 18 is to facilitate the movement of the device.

[0047] To better understand the present utility model, the technical solutions of the present utility model will be described in detail below in conjunction with Figures 1 to 3 :

[0048] First, by operating the touch panel 17, the vacuum pump 15 and the temperature control system 16 are started respectively, so that the inside of the box body 1 is in a vacuum state and at a preset temperature; secondly, the box cover 14 is opened, and the storage dish is placed on the second claw 22, so that the storage dish is in a suspended state; then, the PLC computer control terminal is controlled by the touch panel 17, so that the two driving members 3 are started synchronously, and the two claws 2 move towards each other until the two claws 2 clamp the opposite sides of the storage dish. At the same time, according to the size of the storage dish, the degree of interpenetration between the first claw 21 and the second claw 22 in the two claws 2 is different, that is, the storage dish is placed; finally, the box cover 14 is closed, and the experiment is started. The staff can view the experimental situation inside the box body 1 through the observation window 141 and the temperature sensor 142. This device can be applied to storage dishes of different sizes without replacing the card seat, which saves time and effort.
