Description

Technical Field

[0001] The utility model relates to the technical field of microbial cultivation, in particular to a planktonic microorganism sampler. Background Art

[0002] The planktonic microorganism sampler is a highly efficient porous inhalation dust sampler. It is designed based on the particle impact principle and isokinetic sampling theory. The sampling is direct, and the wind speed at the sampling port is basically consistent with the wind speed in the clean room. It can more accurately reflect the concentration of microorganisms in the clean room. During sampling, the dust-carrying air passes through the micropores at high speed and is impacted on the agar surface in the culture dish. These living microorganisms undergo a dynamic rehydration process during the culture process and grow at a high speed, thereby obtaining results faster.

[0003] The planktonic microorganism sampler in the prior art usually includes a base, a sampling pump seat, a porous sampling head and a protective cover. The sampling pump pumps the external airflow through the porous sampling head into the sampling pump seat to achieve sampling. After each sampling, the air inlet of the sampling head needs to be cleaned to prevent the dust and bacteria remaining in the sampling head from affecting the next sampling result. However, the existing porous sampling head is usually an integrated structure with a large number of air inlet holes, which need to be cleaned one by one with tools, and the work efficiency is low.

DETAILED DESCRIPTION

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. "Multiple" in this specification refers to two or more.

[0025] In the description of this specification, the description with reference to the terms "embodiment", "one embodiment" and "one implementation" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or implementation are included in at least one embodiment or implementation of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or implementation. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or implementations in a suitable manner.

[0026] Combination Figure 1-7 As shown, an embodiment of the utility model provides a planktonic microorganism sampler, comprising: a supporting seat 1, a sampling pump head 2, and a connecting handle 5 connecting the supporting seat 1 and the sampling pump head, the top opening of the sampling pump head 2 is covered with an assembly cover 3, the top of the assembly cover 3 is covered with a protective cover 4, a porous sampling cover 6 is embedded in the bottom opening of the sampling pump head 2, and fixing blocks 10 are symmetrically arranged on the inner wall of the sampling pump head 2 and the side of the porous sampling cover 6, the fixing block 10 is fixedly connected to the inner wall of the sampling pump head 2, and the porous sampling cover 6 is fixedly connected to the sampling pump head 2 through the fixing block 10.

[0027] Specifically, the porous sampling cover 6 and the sampling pump head 2 connected by the locking block 10 are connected in a structure that is easy to disassemble. After the porous sampling cover 6 is disassembled, it can be placed in an ultrasonic cleaner as a whole for cleaning, thereby improving the cleaning efficiency of the sampler.

[0028] The edge of the porous sampling cover 6 is provided with a snap-fitting groove 8 , which is in a T-shaped structure, and locking grooves 11 are respectively provided on two symmetrical side surfaces of the head of the snap-fitting groove 8 .

[0029] The surface of the porous sampling cover 6 is provided with a plurality of sampling holes 7 .

[0030] Specifically, after the porous sampling cover 6 and the sampling pump head 2 are installed, the porous sampling cover 6 and the sampling pump head 2 are sealed. When the sampling pump in the sampling pump head 2 is working, the outside air is sucked in through the sampling hole 7. The dust and bacteria carried in the air flow will adhere to the inner wall surface of the sampling hole 7. Therefore, dust and bacteria will rarely adhere to the edge of the porous sampling cover 6, reducing the cleaning range.

[0031] The locking block 10 is in a T-shaped structure, and movable limiting grooves 12 are respectively provided on two symmetrical side surfaces of the head of the locking block 10, and a movable locking groove 13 is provided on the bottom surface of the tail of the locking block 10. The movable locking groove 13 is connected to the movable limiting groove 12, and a plurality of grooves 17 are provided on one side of the movable locking groove 13.

[0032] The movable limiting groove 12 is provided with a locking spring 14 . The locking spring 14 is in a shuttle-shaped structure in a natural state. The middle of the locking spring 14 is an opening structure. The opening of the locking spring 14 enters the movable slot 13 .

[0033] A locking block 15 is embedded in the movable slot 13 , a protrusion 16 is provided on the side of the locking block 15 , the protrusion 16 is structurally matched with the groove 17 , the protrusion 16 is integrally connected with the locking block 15 , and the locking block 15 is movably engaged with the locking block 10 .

[0034] Specifically, the locking spring 14 can be pushed to deform by the locking block 15. After the locking spring 14 is deformed under pressure, its two ends can be embedded in the locking groove 11, completing the locking between the locking block 10 and the porous sampling cover 6, and then realizing the locking connection between the porous sampling cover 6 and the sampling pump head 2. The locking block 15 can be locked after the protrusion 16 on the locking block 15 is embedded and adapted with the corresponding groove 17. Since the elastic force of the locking spring 14 exerts a certain pressure on the locking block 15, the protrusion 16 on the locking block 15 can be prevented from being separated from the groove 17.

[0035] A connecting ear seat 9 is fixedly connected to the side of the sampling pump head 2, the bottom of the connecting handle 5 is fixedly connected to the bearing seat body 1, and the top of the connecting handle 5 is connected to the connecting ear seat 9 through a shaft bolt.

[0036] Specifically, the angle between the sampling pump head 2 and the connecting handle 5 can be adjusted by loosening the shaft bolt to facilitate sampling.

[0037] Although the disclosure is as above, the protection scope of the disclosure is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the disclosure, and these changes and modifications will fall within the protection scope of the utility model.
