DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Such as Figure 1-2As shown in the figure, a freeze-dried reagent ultrasonic mixing and reconstitution mechanism includes a bottom plate 1. At the upper end of the bottom plate 1, there are two support seats 102. Above the support seats 102, there is a vibration plate 3 rotatably connected to the support seats 102. The vibration plate 3 is driven by a motor 2 to swing left and right. At the lower end of the vibration plate 3, there is an ultrasonic transducer 5, as Figure 3 shown. At the upper end of the vibration plate 3, there is a heating plate 9. At the upper end of the heating plate 9, there is a heating base 4 for fixing the reagent bottle.

[0023] At the lower end of the bottom plate 1, there is a support block 103 made of rubber material, which can play a role in shock absorption.

[0024] At the upper end of the bottom plate 1, there is a bracket 101 for fixing the motor 2. A cam 201 is connected to the output shaft of the motor 2. At the lower end of the vibration plate 3, there is a rotating seat 7. The rotating seat 7 is connected to the support seat 102 through a rotating shaft. The side wall of the cam 201 is connected to a first connecting rod 202. The first connecting rod 202 is connected to a second connecting rod 203. The second connecting rod 203 is connected to the rotating seat 7. When the cam 201 rotates, it moves the second connecting rod 203 to swing through the first connecting rod 202. The second connecting rod 203 drives the vibration plate 3 to swing through the rotating seat 7.

[0025] On the side wall of the support seat 102, there is an optoelectronic sensor 6. On the side wall of the second connecting rod 203, there is a detection plate 204 that cooperates with the optoelectronic sensor 6. The detection plate 204 and the optoelectronic sensor 6 cooperate to determine the origin of the vibration plate 3 and ensure that the vibration plate 3 can remain horizontal after stopping.

[0026] There is a heat insulation pad 8 between the heating plate 9 and the vibration plate 3.

[0027] In order to ensure the stability of the reagent bottle, as Figure 4 shown, on the upper end of the heating base 4, there are positioning holes 401 that cooperate with the reagent bottle. Around the positioning holes 401, there are positioning blocks 402 for fixing the reagent bottle.

[0028] During use, the reagent bottle is fixed in the positioning hole 401. The motor 2 drives the heating base 4 to swing left and right. The freeze-dried powder solution in the reagent bottle shakes and mixes in the bottle. At the same time as the swing, the ultrasonic transducer 5 accelerates the dissolution of the freeze-dried powder solution in the reagent bottle. The temperature of the heating base 4 is controlled by the heating plate 9, so that the freeze-dried powder reagent solution in the reagent bottle is at a stable temperature that is easy to dissolve.

[0029] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these modifications and variations.
