Description

Technical Field

[0001] This utility model relates to the field of quantitative extraction equipment for spore powder and bacterial liquid, and in particular to a quantitative extraction device for spore powder and bacterial liquid. Background Technology

[0002] In the spore powder processing flow, the sterilization process efficiently kills harmful microorganisms, providing a safe and stable source of bacteria for subsequent experiments. After sterilization, the rinsing and precipitation process converts the spore powder into a bacterial suspension required for the experiment.

[0003] However, existing quantitative extraction devices are prone to spore powder particles seeping out during the separation process, which significantly reduces the concentration of effective components in the bacterial solution. This concentration fluctuation directly affects the repeatability and data reliability of subsequent experiments such as microbial culture and activity detection. Furthermore, it cannot quickly extract 10 ml or 20 ml of bacterial solution as needed, affecting experimental efficiency. Utility Model Content

[0004] (a) Technical problems to be solved To address the aforementioned problems in the prior art, this invention provides a quantitative extraction device for spore powder bacterial solution, which can more conveniently and efficiently extract 10 ml or 20 ml of bacterial solution for use, and reduces the leakage of spore powder particles during the extraction process to ensure the experimental concentration of the bacterial solution.

[0005] (II) Technical Solution To achieve the above objectives, the main technical solutions adopted by this utility model include: A device for quantitative extraction of spore powder bacterial liquid includes a sampling bottle, a mounting cap, and a quantitative separation mechanism. The upper part of the sampling bottle is detachably connected to the inside of the mounting cap, and the mounting cap is provided with the quantitative separation mechanism. The quantitative separation mechanism is movably connected to the inside of the sampling bottle. The quantitative separation mechanism includes a pressing rod, a quantitative limiting component, a piston, and a filter barrier. The pressing rod passes through the middle of the mounting cover, and the piston is located at the lower part of the pressing rod. The piston is movably connected to the inside of the sampling bottle. The piston has several drainage holes, each containing a cross-shaped valve made of silicone material. The filter barrier is located at the bottom of the piston, covering the bottom of the drainage holes. The pressing rod has a first limiting hole and a second limiting hole from top to bottom. The quantitative limiting component is detachably connected to both the first and second limiting holes, and is movably connected to the top surface of the mounting cover.

[0006] Furthermore, the quantitative limiting component includes a limiting platform, a sliding key, and a pin. The pressing rod is provided with a sliding groove. The limiting platform is slidably connected to the inside of the sliding groove through the sliding member. The bottom of the limiting platform is movably connected to the top of the mounting cover. After passing through the limiting platform, the pin can be detachably connected to the first limiting hole or the second limiting hole.

[0007] Furthermore, the upper part of the sampling bottle is provided with a first external thread, and the inside of the mounting cap is provided with a first internal thread. The sampling bottle is detachably connected to the inside of the mounting cap through the first external thread and the first internal thread.

[0008] Furthermore, the pin tail is provided with a second external thread, and the other side of the limiting platform is provided with a second internal thread hole, and the second external thread and the second internal thread hole are detachably connected.

[0009] Furthermore, the mounting cover is provided with a waste liquid outlet, and a plug is detachably connected to the waste liquid outlet.

[0010] Furthermore, the sampling bottle is a transparent container.

[0011] Furthermore, the lower part of the sampling bottle is marked with a 10 ml liquid level mark and a 20 ml liquid level mark from bottom to top.

[0012] (III) Beneficial Effects The beneficial effects of this invention are as follows: In actual production and use, the bacterial solution extracted from the rinsing water is placed in a sampling bottle, and then the sampling bottle is installed with the mounting cap. When 10 ml of bacterial solution is needed for the experiment, the quantitative limiting component is installed on the first limiting hole. When 20 ml of bacterial solution is needed for the experiment, the quantitative limiting component is installed on the second limiting hole. After the experimenter installs the quantitative limiting component into the appropriate hole, the piston is pressed into the sampling bottle by pressing the lever until the quantitative limiting component abuts against the top surface of the mounting cap. As the piston descends, the sample is taken. The spore powder in the bottle is blocked by the filter barrier below the piston. Excess water passes through the filter barrier and squeezes the cross-shaped valve made of silicone, causing the drain outlet to open and allowing the excess water to flow to the top of the piston. The volume of bacterial solution from the bottom of the piston to the bottom of the sampling bottle is the amount of bacterial solution required for the experiment. The experimental bacterial solution can then be obtained by separating the sampling bottle from the cap. This allows for more convenient and efficient extraction of 10 ml or 20 ml of bacterial solution for use, while reducing the leakage of spore powder particles during the extraction process and ensuring the experimental concentration of the bacterial solution.

Detailed Implementation

[0020] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Please refer to Figures 1 to 6 As shown, the present invention provides a quantitative extraction device for spore powder bacterial liquid, comprising a sampling bottle 5, a mounting cap 6, and a quantitative separation mechanism 1. The upper part of the sampling bottle 5 is detachably connected to the interior of the mounting cap 6, and the mounting cap 6 is provided with the quantitative separation mechanism 1, which is movably connected to the interior of the sampling bottle 5. The quantitative separation mechanism 1 includes a pressing rod 101, a quantitative limiting component, a piston 104, and a filter barrier 109. The pressing rod 101 passes through the middle of the mounting cover 6. The piston 104 is located at the lower part of the pressing rod 101 and is movably connected to the inside of the sampling bottle 5. The piston 104 is provided with several drainage holes 103, and each drainage hole 103 is provided with a cross-shaped valve 105 made of silicone. The filter barrier 109 is located at the bottom of the piston 104 and covers the bottom of several drainage holes. The pressing rod 101 is provided with a first limiting hole 102 and a second limiting hole 107 from top to bottom. The quantitative limiting component is detachably connected to the first limiting hole 102 and the second limiting hole 107 respectively. The quantitative limiting component is movably connected to the top surface of the mounting cover 6.

[0022] The working principle of this utility model is as follows: In actual production and use, the bacterial solution extracted from the rinsing water is placed in the sampling bottle 5, and then the sampling bottle 5 is installed with the mounting cap 6. When the experiment requires 10 ml of bacterial solution, the quantitative limiting component is installed on the first limiting hole 102. When the experiment requires 20 ml of bacterial solution, the quantitative limiting component is installed on the second limiting hole 107. After the experimenter installs the quantitative limiting component into the appropriate hole position, the piston 104 is pressed into the sampling bottle 5 by pressing the rod 101 until... The quantitative limiting component abuts against the top surface of the mounting cap 6. As the piston 104 descends, the spore powder in the sampling bottle 5 is blocked below the piston 104 by the filter barrier 109. Excess water passes through the filter barrier 109 and squeezes the silicone cross-shaped valve 105, causing the drain outlet to open and allowing the excess water to flow above the piston 104. The volume of bacterial solution from below the piston 104 to the bottom of the sampling bottle 5 is the amount of bacterial solution required for the experiment. Subsequently, the experimental bacterial solution can be obtained by separating the sampling bottle 5 from the mounting cap 6.

[0023] Furthermore, the quantitative limiting component includes a limiting platform 108, a sliding key 110, and a pin 106. The pressing rod 101 is provided with a sliding groove. The limiting platform 108 is slidably connected to the inside of the sliding groove through the sliding member. The bottom of the limiting platform 108 is movably connected to the top of the mounting cover 6. After passing through the limiting platform 108, the pin 106 can be detachably connected to the first limiting hole 102 or the second limiting hole 107.

[0024] As can be seen from the above description, when it is necessary to adjust the quantitative quantity, the pin 106 can be separated from the pressing rod 101, and then the limiting platform 108 can be slid on the pressing rod 101 by the sliding key 110, so that the limiting platform 108 slides to the first limiting hole 102. Then the pin 106 is inserted into one side of the limiting platform 108 and into the first limiting hole 102, and then inserted into the other side of the limiting platform 108 for connection, so that the pressing rod 101 limits the downward pressure of the piston 104 through the limiting platform 108, thereby limiting the sampling amount in the sampling bottle 5. The first limiting hole 102 is for sampling 10 ml, and the second limiting hole 107 is for sampling 20 ml.

[0025] Furthermore, the sampling bottle 5 is provided with a first external thread 8 on its upper part, and the mounting cover 6 is provided with a first internal thread 7 inside. The sampling bottle 5 is detachably connected to the inside of the mounting cover 6 through the first external thread 8 and the first internal thread 7.

[0026] As can be seen from the above description, it is beneficial to better disassemble and assemble the mounting cap 6 and the sampling bottle 5 through the first external thread 8 and the first internal thread 7.

[0027] Furthermore, the pin 106 is provided with a second external thread at its tail, and the limiting platform 108 is provided with a second internal thread hole on the other side, and the second external thread and the second internal thread hole are detachably connected.

[0028] As can be seen from the above description, this helps the pin 106 to be better fixed to the limiting table 108 through the second external thread, preventing the pin 106 from slipping off.

[0029] Furthermore, the mounting cover 6 is provided with a waste liquid outlet 9, and a plug 2 is detachably connected to the waste liquid outlet 9.

[0030] As can be seen from the above description, when the piston 104 is pressed down, the experimenter can remove the plug 2 on the waste liquid port 9 to discharge the excess liquid from the waste liquid port 9, so that during the process of the piston 104 being reset after sampling, the liquid above the piston 104 will not flow into the bottom of the piston 104.

[0031] Furthermore, the sampling bottle 5 is a transparent container.

[0032] As can be seen from the above description, it is beneficial to better observe the movement of piston 104.

[0033] Furthermore, the lower part of the sampling bottle 5 is respectively provided with a liquid level mark line of 10 ml and a liquid level mark line of 20 ml from bottom to top.

[0034] As can be seen from the above description, it is helpful to observe more intuitively whether the piston 104 is pressed to the marked line position. Example 1
