Description

Technical Field

[0001] This utility model relates to the field of microbial collection technology, specifically a filtration device for microbial collection. Background Technology

[0002] Microbial collection refers to the process of collecting microbial samples from different environments (such as soil, water, air, and organisms). It is a fundamental step in microbiological research, industrial applications (such as fermentation and bioremediation), or medical diagnosis. When collecting microorganisms in water, a filter device is installed on the collection tube to filter out waste in the water and prevent it from entering the collection tube.

[0003] Existing filtration devices have the following problems:

[0004] When the filter cover of the existing filter device is installed in the collection cylinder, most of them use threaded connection. Threaded connection not only requires alignment, but is also prone to slippage, which makes the installation inconvenient. Utility Model Content

[0005] The purpose of this invention is to provide a filtration device for collecting microorganisms to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a microbial collection filtration device, comprising a collection cylinder, a filter cover provided on the collection cylinder, a filter screen provided on the filter cover, a docking structure provided on the surface of the filter cover, the docking structure including a lifting opening, the lifting opening provided on the surface of the filter cover, an insertion port provided on the surface of the collection cylinder, a locking slot provided in the insertion port, a plug provided at the bottom end of the filter cover, an elastic connector fixed inside the plug, and a locking head provided at the end of the elastic connector.

[0007] Preferably, at least two sockets are provided and are symmetrically arranged on the collection tube, and the number of plugs is the same as the number of sockets.

[0008] Preferably, the opening is annular and is arranged around the surface of the filter cover.

[0009] Preferably, the opening of the socket is flared, and the flared part is inclined.

[0010] Preferably, after the plug is inserted into the socket, the left and right sides of the plug rest against the inside of the socket.

[0011] Preferably, the plug is provided with two elastic connectors, and the two elastic connectors have the same structure.

[0012] Preferably, one end of the clip protrudes from the surface of the plug, and the protruding surface of the clip is an arc surface.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] When installing the filter cover, insert the plug into the socket. The socket will retract the locking head, and the locking head will deform under the force, generating elastic force. When the plug is fully inserted into the socket, the elastic connector will push the locking head back to its original position, and the locking head will lock into the socket, thus fixing the filter cover to the collection cylinder. When disassembling, lift the filter cover through the lifting port. The locking head will be pressed into the plug under the force. After the locking head separates from the socket, the plug will separate from the socket, completing the disassembly. This achieves the beneficial effect of convenient disassembly and assembly. The disassembly and assembly of the filter cover is relatively convenient through the docking structure. Attached Figure Description

[0021] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0022] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides a filtration device for collecting microorganisms, including a collection cylinder 1, a filter cover 2 installed on the collection cylinder 1, a filter screen 3 integrally formed on the filter cover 2, and a docking structure 4 provided on the surface of the filter cover 2.

[0023] Specifically, when it is necessary to collect microorganisms in the water, the collection tube 1 is placed in the water and will sink into the water. Water will enter the collection tube 1, and at the same time, the water will pass through the filter screen 3, which will filter out the garbage in the water. The microorganisms will also enter the collection tube 1 along with the water for collection.

[0024] Please see Figure 2 , Figure 3 , Figure 4 and Figure 5 This utility model provides a filter device for collecting microorganisms. The docking structure 4 includes a lifting opening 41, which is annular and surrounds the surface of the filter cover 2 for easy removal of the filter cover 2.

[0025] In this utility model, the surface of the collecting cylinder 1 is integrally formed with an insertion port 42. There are four insertion ports 42, which are arranged in a cross shape and fixed on the collecting cylinder 1. The insertion port 42 is integrally formed with a snap 43. Alternatively, two insertion ports 42 can be arranged symmetrically. The opening of the insertion port 42 is flared and the flared opening is inclined.

[0026] In this utility model, the bottom end of the filter cover 2 is integrally formed with a plug 44. The number of plugs 44 is the same as the number of sockets 42. An elastic connector 45 is fixed inside the plug 44. A clip 46 is provided at the end of the elastic connector 45. One end of the clip 46 protrudes from the surface of the plug 44. The protruding surface of the clip 46 is an arc surface, which facilitates docking and disassembly. Two elastic connectors 45 are provided in the plug 44. The two elastic connectors 45 have the same structure.

[0027] When the plug 44 is inserted into the socket 42, the left and right sides of the plug 44 rest against the inside of the socket 42 to prevent it from tilting.

[0028] Specifically, when installing the filter cover 2, the plug 44 is inserted into the socket 42. The socket 42 will retract the locking head 46. The locking head 46 is subjected to force, causing the elastic connector 45 to deform and generate elastic force. When the plug 44 is fully inserted into the socket 42, the elastic connector 45 will push the locking head 46 back to its original position, and the locking head 46 will be locked in the slot 43, thus fixing the filter cover 2 onto the collection cylinder 1. When disassembling, the filter cover 2 is lifted through the lifting port 41. The locking head 46 is pressed into the plug 44 under force. After the locking head 46 separates from the slot 43, the plug 44 will separate from the socket 42, completing the disassembly. This achieves the beneficial effect of convenient disassembly and assembly. The disassembly and assembly of the filter cover 2 is relatively convenient through the docking structure 4.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
