[0018] The above and other technical contents, features and effects of the present invention are described in detail below with reference to the attached Figure 1-5 The detailed description of the embodiments will clearly show that the structural contents mentioned in the following embodiments are all based on the accompanying drawings.
[0019] Various exemplary embodiments of the present invention will be described below with reference to the accompanying drawings.
[0020] Embodiment 1, a multifunctional collection device for microbial detection samples, comprising a housing 1, characterized in that a lifting plate 2 is slidably provided in the housing 1, the lifting plate 2 is provided with two sets of sliding grooves 3, a sampling frame 4 is slidably connected in the two sets of sliding grooves 3, the sampling frame 4 is provided with a sampling groove 5, a stirring paddle 6 is rotatably connected to the lifting plate 2, the sampling frame 4 is provided with a matching groove 7 for matching with the stirring paddle 6, and the stirring paddle 6 is driven by a power device;
[0021] Electromagnets 8 are provided in both sets of sliding slots 3, and an armature 9 cooperating with the electromagnets 8 is provided on the sampling frame 4. A return spring 10 is provided between the electromagnets 8 and the armature 9.
[0022] The housing 1 is threadedly connected to an adjusting screw 11 that is rotatably connected to the lifting plate 2, and the adjusting screw 11 is provided with an adjusting handle 12;
[0023] The power device includes a motor 13 fixedly connected to the lifting plate 2, an auxiliary connecting frame 14 cooperating with the motor 13 is provided on the lifting plate 2, the adjusting screw 11 is rotatably connected to the auxiliary connecting frame 14, the stirring paddle 6 is driven by the motor 13, and the motor 13 is electrically connected to the controller;
[0024] One group of the sampling frames 4 is provided with a sealing protrusion 15, and the other group of the sampling frames 4 is provided with a sealing groove 16 corresponding to the sealing protrusion 15;
[0025] The matching groove 7 is provided with a sealing gasket that matches the stirring paddle 6.
[0026] When in use, the device is moved to the sampling position, and the adjustment handle 12 is rotated to drive the adjustment screw 11 to rotate, so that the lifting plate 2 is lowered, and the sampling frame 4 slides out from the inner wall of the shell 1 and enters the sample to take the sample. Then, the electromagnet 8 is energized by the controller to generate magnetism, which attracts the armature 9. The two sets of sampling frames 4 overcome the elastic force of the return spring 10 and cooperate with each other. The sealing protrusion 15 cooperates with the sealing groove 16, so that the two sets of sampling frames 4 are tightly fitted, and the sample is placed in the sample slot;
[0027] When the two sets of sampling frames 4 are matched, the rotating shaft of the stirring paddle 6 is inserted into the matching groove 7. The matching groove 7 is designed to be slightly larger than the diameter of the rotating shaft of the stirring paddle 6. A sealing ring is provided in the matching groove 7. The sealing ring does not fit tightly with the rotating shaft of the stirring paddle 6 and does not affect the rotation of the rotating shaft.
[0028] During sampling, the sample will not completely fill the sampling slot 5, so the sample cannot leak out from the matching slot 7 and the rotating shaft end of the stirring paddle 6. In addition, the gap between the matching slot 7 and the rotating shaft end of the stirring paddle 6 is very small and is located inside the housing 1, so it will not affect the sampling result. When the adjusting screw 11 is rotated in the reverse direction, the lifting plate 2 and the two sets of sampling frames 4 are moved to the interior of the housing 1. If necessary, the bottom of the housing 1 can be sealed with a cover plate to complete the sampling task.
[0029] After completing the sampling task, when the sample needs to be placed, the shell 1 is moved as a whole to the sampling position, and the adjusting screw 11 is rotated to move the lifting plate 2 and the two sets of sampling frames 4 to the outside of the shell 1. The electromagnet 8 is disconnected by the controller and loses its magnetism. Under the action of the reset spring 10, the two sets of sampling frames 4 are separated, so that the sample falls to the sampling location, the sampling groove is cleaned, and it is moved to the inside of the shell 1, and the sampling task is completed.
[0030] After the sampling task is completed, in order to prevent the sample from settling when transporting the sample, the motor 13 can be started to drive the stirring paddle 6 to rotate, so that the stirring paddle 6 stirs in the placement tank to prevent the sample from settling.
[0031] The above description is only for the purpose of illustrating the present invention. It should be understood that the present invention is not limited to the above embodiments, and various variations that conform to the concept of the present invention are within the scope of protection of the present invention.
