Description

Technical Field

[0001] This utility model relates to the field of microbial testing instruments, specifically to a microbial testing extractor. Background Technology

[0002] When conducting microbial testing on pharmaceuticals, some drugs, such as viscous oils containing oily matrices like petrolatum and silicone oil, cannot be fully mixed with water-soluble diluents. Therefore, for such test samples, it is necessary to dissolve them in isopropyl myristate, then add the diluent and perform shaking extraction, allowing the mixture to stand to separate the oil and water layers, and then using the aqueous layer as the test solution. However, emulsification is prone to occur during this process. Based on this issue, the applicant discovered Chinese utility model patent CN209662666U, which discloses a microbial testing extractor that uses heating to separate the emulsion layer... While this method gradually eliminates the emulsification problem, it has some shortcomings. For example, the location of the emulsion layer varies depending on the type and amount of sample added to the extraction bottle. As shown in the accompanying diagram of the prior art, the extraction bottle is generally conical in shape. This means that when heating the emulsion layer, the arc-shaped plate used as the heating medium may not be able to adhere tightly to the outer surface of the extraction bottle, resulting in relatively poor heating effect, which needs further improvement. Furthermore, the prior art uses shaking to mix the solution in the extraction bottle, which is time-consuming and labor-intensive, and requires further improvement.

[0003] Based on the above, the present invention proposes a microbial testing extractor. Utility Model Content

[0004] To address the problems mentioned in the background above, this invention provides a microbial testing extractor.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows.

[0006] A microbial testing extractor includes an extraction rack and an extraction flask mounted on the extraction rack. A connecting arm extends from the extraction rack, and an upper inlet pipe extends from the upper end of the extraction flask. The upper inlet pipe is ball-jointed with the suspended end of the connecting arm. A lower outlet pipe extends from the lower end of the extraction flask. A mixing component is mounted on the extraction rack to drive the lower outlet pipe to shake, thereby causing the extraction flask to sway around the ball-joint between the extraction flask and the connecting arm. A heating component is provided on the extraction rack to heat the extraction flask. When heating, the heating end of the heating component is in contact with the outer surface of the extraction flask.

[0007] Furthermore, the hybrid component includes a slide block, on which a ball is hinged and fitted with a sleeve ball. A sleeve hole is provided through the sleeve ball, through which the sleeve ball is fitted onto the outside of the lower drain pipe.

[0008] Furthermore, a vertically arranged motor is installed on the extraction rack, and a rotating disk is coaxially mounted on the output end of the motor. A connecting rod is hinged between the rotating disk and the slide. The hinge axis formed by the hinge between the connecting rod and the rotating disk or the slide is vertically arranged, and the hinge between the connecting rod and the rotating disk is offset from the axis of the rotating disk.

[0009] Furthermore, the heating component includes two sets of heating components located on both sides of the extraction flask, each set of heating components including several sets of heating elements arranged in an array along the vertical direction.

[0010] Furthermore, the heating component includes a telescopic rod mounted on the extraction rack and extending horizontally. A heating plate is provided at the end of the telescopic rod facing the extraction bottle. During the movement of the heating plate driven by the telescopic rod, the arc-shaped heating plate can fit against the outer surface of the extraction bottle.

[0011] Furthermore, the heating plate is made of a heat-conducting material, and an electric heating wire is installed inside the heating plate to heat it.

[0012] Furthermore, the heating plate has a mounting hole on the side facing the extraction bottle, and a laser lamp is installed in the mounting hole.

[0013] Compared with the prior art, the advantages of this utility model are as follows:

[0014] 1. This solution uses a motor to drive the rotating disk to rotate. During the rotation, the connecting rod pushes and pulls the slide. Since the slide and the lower drain pipe are connected by a ball joint and a sliding joint, the connecting rod can push and pull the slide to drive the extraction bottle to swing around the ball joint between the extraction bottle and the connecting arm, thereby making the solution in the extraction bottle as homogeneous as possible and achieving a better mixing effect.

[0015] 2. This solution uses a laser light to help determine which heating plate is directly opposite the emulsion layer. Then, the corresponding telescopic rod drives the heating plate to move until it is in contact with the extraction bottle. The heating plates in the two sets of heating components work together to form a complete ring shape, which firmly wraps the emulsion layer, so that the heat can be fully and evenly transferred to the emulsion layer, causing the emulsion layer to be heated and disappear quickly.

[0022] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments. Example

[0023] Reference Figures 1-3 A microbial testing extractor includes an extraction rack 1 and an extraction bottle 2 mounted on the extraction rack 1. Specifically, a connecting arm 101 extends from the extraction rack 1, and an upper liquid inlet pipe 201 extends from the upper end of the extraction bottle 2. The upper liquid inlet pipe 201 is ball-jointed with the suspended end of the connecting arm 101.

[0024] The lower end of the extraction bottle 2 extends into a lower drain pipe 202. A mixing component 3 drives the lower drain pipe 202 to shake, thereby ensuring uniform mixing of the solution within the extraction bottle 2. Specifically, the mixing component 3 includes a motor 301 and a slide 203. A ball is hinged to the slide 203, and a through hole is formed in the ball, allowing it to be fitted onto the outside of the lower drain pipe 202. The motor 301 is vertically arranged, and a rotating disk 302 is coaxially mounted on its output end. A connecting rod 303 is hinged between the rotating disk 302 and the slide 203. The hinge axes formed by these two hinges are both vertically arranged, and the hinge point between the connecting rod 303 and the rotating disk 302 is offset from the rotation axis. The axis of disk 302; the rotating disk 302 is driven to rotate by motor 301. During the rotation, the sliding block 203 is pushed and pulled by connecting rod 303. Since the sliding block 203 and the lower drain pipe 202 are connected by a ball joint and a sliding joint, the connecting rod 303 can push and pull the sliding block 203 to drive the extraction bottle 2 to swing around the ball joint between the extraction bottle 2 and the connecting arm 101, so that the solution in the extraction bottle 2 is mixed as evenly as possible. It should be noted that the upper inlet pipe 201 and the lower drain pipe 202 are each equipped with a valve. The former is used for the solution to enter the extraction bottle 2, and the latter is used for the solution in the extraction bottle 2 to be discharged outward. Example

[0025] Reference Figure 1 and Figure 4To address the emulsification problem mentioned in the background section, a heating element 4 is provided on the extraction rack 1 to heat the emulsion layer. Specifically:

[0026] The heating element 4 includes two sets of heating components located on both sides of the extraction bottle 2.

[0027] Each heating assembly includes several groups of heating elements arranged in an array along the vertical direction.

[0028] The heating component includes a telescopic rod 402 mounted on the extraction rack 1 and extending horizontally. A heating plate 401 is provided at the end of the telescopic rod 402 facing the extraction bottle 2. It should be noted that during the movement of the heating plate 401 driven by the telescopic rod 402, the heating plate 401 is in an arc shape and can fit against the outer surface of the extraction bottle 2. Therefore, the size of the heating plate 401 in the heating component at different heights is different. In addition, the heating technology of the heating plate 401 can adopt existing electric heating technology. For example, the side of the heating plate 401 facing the extraction bottle 2 is made of a thermally conductive material, such as copper. An electric heating wire is provided inside the heating plate 401. Heat is conducted to the heating plate 401 and then to the extraction bottle 2 by energizing the electric heating wire. The telescopic rod 402 can be an electric telescopic rod or a manual telescopic rod, which will not be described in detail.

[0029] Preferably, the heating plate 401 has a mounting hole on the side facing the extraction bottle 2, and a laser lamp is installed in the mounting hole.

[0030] If emulsification occurs during use, the laser light is turned on first to determine which heating plate 401 is facing the emulsion layer. Then, the corresponding telescopic rod 402 is activated, driving the heating plate 401 to move into contact with the extraction bottle 2 and face the emulsion layer. The heating plates 401 in the two sets of heating components cooperate to form a complete ring shape to firmly wrap the emulsion layer, so as to transfer heat to the emulsion layer fully and evenly, so that the emulsion layer is heated and disappears quickly.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
