Technical Field

[0001] This utility model relates to the technical field of coating rods, and in particular to a sterilization device for coating rods used in clean benches. Background Technology

[0002] In microbiological experiments, dilution plating is one of the most common methods for calculating bacterial counts. This procedure requires a large number of plating sticks. In routine experiments, it is usually necessary to prepare a large number of plating sticks, wrap them, sterilize and dry them, and then place them in a clean bench for later use. This process is also time-consuming, and improper operation may lead to contamination. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this application provides a sterilization device for coating rods in a clean bench.

[0004] This application provides a sterilization device for a clean bench using a coating rod, which adopts the following technical solution:

[0005] A sterilization device for coating rods in a clean bench includes a base and a mounting base. The mounting base has a plurality of placement holes evenly provided for placing coating rods. The mounting base is provided with a fixing component for fixing the position of the coating rods. The interior of the base is hollow for placing fuel. The top of the base has a combustion groove with a semi-circular cross-section. The base is provided with a combustion module for igniting the fuel.

[0006] By adopting the above technical solution, the coating rod is adjusted to a suitable position in the placement hole according to the height and length of the front end. Then, the coating rod is burned by the combustion module. After that, the second coating rod is used (default two minutes). After the second coating rod is used, the combustion module stops burning the first coating rod. The heated coating rod is removed and placed in an upright position under the airflow of the clean bench for rapid cooling. The above flame burning operation is repeated for the second coating rod. Four coating rods are used as a group and are used in a cycle. This reduces the accumulation of coating rods on the clean bench, shortens the operation time, and simplifies the preparation of experimental materials.

[0007] Optionally, the fixing component includes multiple fixing rods, which are evenly arranged on both sides of the placement hole and slidably mounted on the mounting base. A return spring is provided at the end of the fixing rod away from the placement hole, and the other end of the return spring is connected to the mounting base.

[0008] By adopting the above technical solution, the fixing rods located on both sides of the placement hole play a role in limiting and fixing the coating rod, so as to facilitate the subsequent use of the combustion module to sterilize the coating rod by flame burning.

[0009] Optionally, a guide block is provided at the end of the fixing rod away from the reset spring.

[0010] By adopting the above technical solution, it is easier for the coating rod to push the fixed rod to move.

[0011] Optionally, the base is provided with a transparent observation window, and the base has a fuel filling port with a plug.

[0012] By adopting the above technical solution, staff can easily observe the remaining fuel level inside the base through a transparent observation window.

[0013] Optionally, a heat-insulating coating is provided on the inner wall of the placement hole.

[0014] By adopting the above technical solutions, the fire resistance of the mounting base can be enhanced.

[0015] Optionally, a hook for hanging coating rods is provided on one side of the mounting base.

[0016] By adopting the above technical solution, after the coating rod is sterilized by flame in the placement hole, the heated coating rod is removed and placed on the hook, where it is quickly cooled down by the airflow of the clean bench itself, so that the coating rod can be used.

[0017] Optionally, the base is provided with a liquid spraying assembly, which includes a liquid storage tank, a liquid inlet pipe, a booster pump, and multiple nozzles. The liquid storage tank is disposed on the base, and the multiple nozzles are evenly embedded in the mounting base, with all the nozzles facing the placement hole. The inlet end of the booster pump is connected to the liquid storage tank, and the outlet end of the booster pump is connected to the liquid inlet pipe. The other end of the liquid inlet pipe is connected to the multiple nozzles respectively.

[0018] By adopting the above technical solution, the alcohol in the storage tank is sprayed onto the coating rod, and the combustion module ignites the fuel in the combustion chamber, thereby sterilizing the coating rod by burning. During the combustion process, the alcohol on the surface of the coating rod will also be ignited, thereby improving the sterilization effect of the coating rod.

[0019] Optionally, a check valve is connected to the liquid inlet pipe.

[0020] By adopting the above technical solution and installing a check valve, the backflow of unsprayed alcohol located inside the nozzle is prevented.

[0021] This utility model has the following advantages:

[0022] 1. By setting up a fixing component, a base, and a combustion module, the used coating rod is placed in the placement hole. Then, the fixing component is used to fix the position of the coating rod. The combustion module ignites the fuel to sterilize the coating rod by burning it. This facilitates the recycling of the coating rod, reduces the accumulation of coating rods on the clean bench, and shortens the operation time.

[0023] 2. By setting a transparent observation window and a fuel filling port, it is easy to observe the remaining fuel inside the base through the transparent observation window;

[0024] 3. By setting up a spray component, the sterilization effect on the coating rod can be improved. Attached Figure Description

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0030] like Figures 1 to 3As shown, a sterilization device for coating rods used in a clean bench includes a base 1 and a mounting base 2. The mounting base 2 has multiple evenly spaced holes 21 for placing coating rods, arranged vertically. A fixing component 3 for securing the coating rods is mounted on the mounting base 2. The base 1 is hollow inside for holding fuel. A combustion groove 11 with a semi-circular cross-section is formed on the top of the base 1, communicating with the bottom of the placement holes 21. A combustion module 12 for igniting the fuel is mounted on the base 1. In use, a package of sterilized stainless steel coating rods is prepared. After coating with the rods, they are inserted into the placement holes 21 and then fixed. The component 3 is fixedly placed on the mounting base 2. Then, it is adjusted to a suitable position in the placement hole 21 according to the height and length of the front end of the coating rod. The coating rod is then burned by the combustion module 12. Then, the second coating rod is used (default two minutes). After the second coating rod is used, the burning of the first coating rod is stopped by the combustion module 12. The heated coating rod is taken out from the placement hole 21 and cooled down quickly under the airflow of the clean bench. The above flame burning operation is repeated for the second coating rod. Four coating rods are used as a group and are used in a cycle, thereby reducing the accumulation of coating rods on the clean bench, shortening the operation time, and simplifying the preparation of experimental materials.

[0031] In this embodiment, the combustion module 12 includes a nozzle, a conduit, a piezoelectric ceramic igniter, etc., forming a common lighter mechanism. Liquid butane is stored in the base 1. Since the lighter structure is existing technology, the specific components of the combustion module 12 will not be described in detail in this embodiment. When in use, the piezoelectric ceramic igniter is pressed to ignite the butane.

[0032] like Figures 1 to 3 As shown, the fixing component 3 includes multiple fixing rods 31, which are evenly installed on both sides of the placement hole 21. The fixing rods 31 are slidably installed on the mounting base 2. A return spring 32 is installed at the end of the fixing rod 31 away from the placement hole 21, and the other end of the return spring 32 is connected to the mounting base 2. In use, the coating rod is inserted vertically into the placement hole 21. The bottom of the coating rod will push the fixing rods 31 located on both sides of the placement hole 21 to move, so that the return spring 32 is compressed. This causes the fixing rods 31 to tend to return to their original length, thereby limiting and fixing the coating rod with the fixing rods located on both sides of the placement hole 21, so that the coating rod can be sterilized by flame burning using the combustion module 12.

[0033] like Figures 1 to 3As shown, a guide block 33 is fixedly installed at the end of the fixing rod 31 away from the return spring 32. The guide block 33 has an inclined surface. When the coating rod is inserted from the top of the placement hole 21, the bottom of the coating rod slides against the inclined surface on the guide block 33. The coating rod pushes the fixing rod 31 to move away from the coating rod. Under the action of the return spring 32, the guide block 33 abuts against the surface of the coating rod, thereby clamping and fixing the coating rod.

[0034] like Figures 1 to 3 As shown, a transparent observation window 13 is provided on the base 1, and a fuel filling port 14 is provided on the base 1. A plug 15 for sealing itself is provided on the fuel filling port 14. In use, the operator can easily observe the fuel level inside the base 1 through the transparent observation window 13. When the level is low, the operator adds fuel to the base 1 through the fuel filling port 14. In this embodiment, the transparent observation window 13 is made of polycarbonate. In other embodiments, it can also be made of polymethyl methacrylate, polystyrene, or other materials.

[0035] like Figures 1 to 3 As shown, the inner wall of the placement hole 21 is coated with a heat-insulating coating. By brushing the heat-insulating coating onto the surface of the material, the fire resistance of the material can be improved, the flame spread rate can be slowed down, or combustion can be stopped for a certain period of time. In this embodiment, the heat-insulating coating uses a liquid ceramic heat-insulating coating agent, model T-001A. In other embodiments, heat-insulating coatings of other materials can also be used.

[0036] like Figures 1 to 3 As shown, a hook 16 for hanging coating rods is installed on one side of the mounting base 2; after the coating rod is sterilized by flame in the placement hole 21, the heated coating rod is removed and placed on the hook 16, and quickly cooled down under the airflow of the clean bench itself, so that the coating rod can be used.

[0037] like Figures 1 to 3As shown, a spray assembly 4 is installed on the base 1. The spray assembly 4 includes a storage tank 41, an upper liquid pipe 42, a booster pump 43, and multiple nozzles 44. The storage tank 41 is installed on the base 1, and the multiple nozzles 44 are evenly embedded in the mounting base 2, with all nozzles 44 facing the placement hole 21. The inlet end of the booster pump 43 is connected to the storage tank 41, and the outlet end of the booster pump 43 is connected to the upper liquid pipe 42. The other end of the upper liquid pipe 42 is connected to the multiple nozzles 44 respectively. In use, alcohol is placed in the storage tank 41. Inside the process 1, when the operator places the coating rod into the placement hole 21 and clamps and fixes the coating rod with the fixing component 3, the booster pump 43 is started. The booster pump 43 pumps alcohol from the storage tank 41 into the upper liquid pipe 42, and then sprays it onto the coating rod through multiple nozzles 44, thereby wetting the surface of the coating rod. Then, the fuel is ignited in the combustion tank 11 through the combustion module 12, thereby sterilizing the coating rod by burning. During the combustion process, the alcohol on the surface of the coating rod will also be ignited, thereby improving the sterilization effect of the coating rod.

[0038] like Figures 1 to 3 As shown, a check valve 45 is connected to the upper liquid pipe 42. By installing the check valve 45, the backflow of alcohol that has not been sprayed out inside the nozzle 44 is prevented.

[0039] The implementation principle of this embodiment is as follows: After use, the coating rod is inserted into the placement hole 21 and fixed on the mounting base 2 under the action of the fixing component 3. Then, the fuel is ignited by the combustion module 12 to burn the coating rod. Then, the second coating rod is used (default two minutes). After the second coating rod is used, the burning of the first coating rod is stopped. The heat-sterilized coating rod is removed and placed in an upright position under the airflow of the clean bench for rapid cooling. The above flame burning operation is repeated for the second used coating rod. Four coating rods are used as a group and are used in a cycle, thereby reducing the accumulation of coating rods on the clean bench, shortening the operation time, and simplifying the preparation of experimental materials.

[0040] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technology of this utility model without departing from the scope of the technical solution of this utility model shall fall within the protection scope of this technical solution.
