Description

Technical Field

[0001] This utility model belongs to the technical field of microbial detection and sampling equipment, specifically relating to microbial detection and sampling equipment. Background Technology

[0002] Airborne microorganisms refer to various microorganisms suspended in the air, including bacteria, fungi, viruses, algae, protozoa, etc. They are an important component of atmospheric bioaerosols. These microorganisms are widely present in the natural environment and places where humans are active, and are closely related to human health, ecological balance and industrial production.

[0003] To ensure public health, industrial safety, and ecological balance, operators use airborne dust and bacteria samplers to collect microorganisms from the air. This allows operators to collect airborne microorganisms on the surface of agar culture medium in the equipment's petri dishes. By incubating the culture dishes, the types, concentrations, and levels of pollution of airborne microorganisms can be determined based on the incubation data, facilitating subsequent processing. However, some airborne dust and bacteria samplers have exhaust vents at the rear of the equipment that are directly exposed to the environment. When the equipment is not in use, dust or debris from the environment can easily enter the equipment through the exhaust vents and accumulate inside. Over time, this accumulation of dust or debris can affect the operation of the internal components of the equipment.

[0004] Therefore, this invention provides a microbial detection and sampling device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a microbial detection and sampling device, which aims to solve the problem that some existing airborne dust and bacteria samplers have an exhaust vent at the rear end when in use, but the exhaust vent is directly exposed to the environment. When the device is not in use, dust or debris in the environment can easily enter the device through the exhaust vent and accumulate inside. After a period of accumulation, this dust or debris will affect the operation of the internal components of the device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a microbial detection sampling device, comprising a sampler body, an exhaust port on the rear surface of the sampler body, a mounting frame connected to the rear surface of the sampler body outside the exhaust port, hinges symmetrically connected to the bottom surface of the mounting frame, the movable end of the hinges connected to the bottom surface of a rotating block, a baffle connected to the top surface of the rotating block, a positioning block symmetrically connected to the top end of the baffle facing the mounting frame, one end of the positioning block extending into a positioning groove, the positioning groove symmetrically opened on the end surface of the mounting frame away from the sampler body, locking blocks connected to both sides of the positioning block, one end of the locking block engaging into the inside of a locking groove, the locking groove symmetrically opened on the inner surface of the positioning groove, and a groove at the center of the top surface of the mounting frame.

[0007] In a preferred embodiment of the microbial detection and sampling device of this utility model, a sealing ring is connected to one end of the baffle facing the mounting frame, and one end of the sealing ring is engaged in a sealing groove, which is located on the end surface of the mounting frame facing the baffle.

[0008] In a preferred embodiment of the microbial detection and sampling device of this utility model, a connecting block is connected to the bottom surface of the baffle, one end of the connecting block extends into the connecting groove, the connecting groove is opened at the middle position of the top surface of the rotating block, and the connecting block and the rotating block are slidably connected through the connecting groove.

[0009] As a preferred embodiment of the microbial detection and sampling device of this utility model, bolts are connected through both sides of the rotating block, and the other end of the bolts forms a threaded connection with the connecting block.

[0010] As a preferred embodiment of the microbial detection and sampling device of this utility model, the sampler body has columns connected to the bottom surface at the four corners, the bottom surface of the columns has threaded grooves, one end of a threaded column is threadedly connected inside the threaded grooves, and a support foot is connected to the bottom surface of the threaded column.

[0011] As a preferred embodiment of the microbial detection and sampling device of this utility model, horizontal bubbles are embedded on both sides of the bottom end of the sampler body.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model utilizes the cooperation of a mounting frame, a rotating block, a baffle, a positioning block, a locking block, and a sealing ring. After the sampler body is used, the baffle can rotate on the mounting frame via the hinge connected to the rotating block, causing the positioning block on the baffle to move into the positioning groove on the mounting frame. At this time, the locking block on the positioning block will engage with the locking groove, fixing the position of the positioning block. The sealing ring on the baffle will also engage with the sealing groove, ensuring the seal between the baffle and the mounting frame. In this way, the baffle and the mounting frame can block and protect the exhaust vent, effectively preventing dust or debris in the environment from entering the equipment through the exhaust vent, and avoiding the accumulation of dust and debris inside the equipment that may affect the operation of the components.

[0014] This invention, through the cooperation of a column, a threaded column, support feet, and a level bubble, allows operators to adjust the height of the support feet by rotating the threaded column according to the actual ground conditions of the usage scenario. This ensures that the sampler body remains horizontal when placed in use, preventing the sampler body from tilting and causing changes in the airflow path, which could result in uneven distribution of microbial particles during sampling and thus affect the reliability of the sampling results.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5 This utility model provides the following technical solution: a microbial detection sampling device, including a sampler body 1, the sampler body 1 being a YP-KF airborne dust and bacteria sampler, an exhaust port 2 being provided on the rear surface of the sampler body 1, an installation frame 3 being connected to the rear surface of the sampler body 1 outside the exhaust port 2, hinges 4 being symmetrically connected to the bottom surface of the installation frame 3, the movable end of the hinges 4 being connected to the bottom surface of the rotating block 5, a baffle 6 being connected to the top surface of the rotating block 5, a positioning block 7 being symmetrically connected to the top end of the baffle 6 facing the installation frame 3, one end of the positioning block 7 extending into the positioning groove 8, the positioning groove 8 being symmetrically opened on the end surface of the installation frame 3 away from the sampler body 1, a locking block 9 being connected to both sides of the positioning block 7, one end of the locking block 9 engaging into the inside of the locking groove 10, the locking block 9 being made of rubber, the locking groove 10 being symmetrically opened on the inner surface of the positioning groove 8, and a groove 21 being provided at the middle position of the top surface of the installation frame 3.

[0024] Preferably, a sealing ring 11 is connected to one end surface of the baffle 6 facing the mounting frame 3, and one end of the sealing ring 11 is engaged in the sealing groove 12, which is located on the end surface of the mounting frame 3 facing the baffle 6.

[0025] In practical use, the sealing ring 11 is made of rubber. When the baffle 6 is fixed to the mounting frame 3 by the locking block 9 on the positioning block 7, the sealing ring 11 on the baffle 6 will also move to the position of the sealing groove 12, so that the sealing ring 11 can be elastically locked in the sealing groove 12, thereby increasing the sealing between the baffle 6 and the mounting frame 3 and preventing dust or debris from entering the exhaust port 2 through the gap between the baffle 6 and the mounting frame 3.

[0026] Preferably, a connecting block 13 is connected to the bottom surface of the baffle 6, one end of the connecting block 13 extends into the connecting groove 14, the connecting groove 14 is opened at the middle position of the top surface of the rotating block 5, and the connecting block 13 and the rotating block 5 are slidably connected through the connecting groove 14.

[0027] In practical use, the connecting block 13 at the bottom of the baffle 6 can slide in the connecting groove 14 on the rotating block 5, so that the baffle 6 can be placed and separated on the rotating block 5 through the connecting block 13.

[0028] Preferably, bolts 15 are connected through both sides of the rotating block 5, and the other end of the bolts 15 is threadedly connected to the connecting block 13.

[0029] In practical use, when the connecting block 13 on the baffle 6 is slidably placed into the connecting groove 14 on the rotating block 5, the bolt 15 is screwed through the rotating block 5 into the connecting block 13, so that the position of the connecting block 13 is fixed in the connecting groove 14, and the baffle 6 can be connected to the rotating block 5 through the connecting block 13. When the bolt 15 is unscrewed, the connecting block 13 can be separated from the connecting groove 14, so that the baffle 6 can be disassembled for maintenance and replacement.

[0030] Preferably, the sampler body 1 has a column 16 connected to the bottom surface at the four corners, the bottom surface of the column 16 has a threaded groove 17, the threaded groove 17 has a threaded connection to one end of a threaded post 18, and the bottom surface of the threaded post 18 has a support foot 19 connected to it.

[0031] In practical use, by turning the support foot 19, the support foot 19 can drive the threaded column 18 to rotate in the threaded groove 17 at the bottom of the column 16, thereby changing the position of the threaded column 18 in the threaded groove 17, and the position of the support foot 19 will also change. In this way, by adjusting the height of the support foot 19, the sampler body 1 can be kept in a horizontal state when placed and used.

[0032] Preferably, horizontal bubbles 20 are embedded on both sides of the bottom end of the sampler body 1.

[0033] In actual use, the operator can observe whether the sampler body 1 is in a horizontal state through the level bubble 20 set on the sampler body 1.

[0034] Working principle: When using this microbial detection sampling device, first place the sampler body 1 at the designated sampling location. If the ground is uneven and the sampler body 1 tilts, turn the support foot 19 at the lower position. This will cause the threaded post 18 connected to the support foot 19 to rotate in the threaded groove 17 on the column 16. The position of the threaded post 18 will change within the threaded groove 17, thus changing the position of the support foot 19. Continue rotating until the operator confirms that the sampler body 1 is level by observing the bubble level 20. A level sampler body 1 ensures stable internal airflow and prevents microbial particles from being trapped during sampling due to tilting. The uneven distribution of the sample medium ensures the accuracy of the sampling results. Then, a petri dish containing agar medium is placed into the sampling port at the top of the sampler body 1, and the sampling head is installed inside the sampling port. A finger is then inserted into the groove 21. The operator can then pinch one end of the baffle 6 and rotate it via the hinge 4 connected to the rotating block 5 on the mounting frame 3. At this point, the locking block 9 on the positioning block 7 will separate from the locking groove 10, allowing the positioning block 7 to slide out of the positioning groove 8. The baffle 6 can then rotate to the lower end of the mounting frame 3, exposing the exhaust vent 2 inside the mounting frame 3. The sampling flow rate and time parameters are then set via the touchscreen on the top of the sampler body 1, and sampling can then be started. The sampler body 1 performs airborne microbial sampling. An internal air pump creates suction at the sampling port, maintaining a constant flow rate. Airborne microbial particles are drawn into the sampling port by the airflow, which then passes through the sampling head, a petri dish, and finally exits through the exhaust port 2. As the airflow passes through the petri dish at the sampling port, airborne microorganisms are collected on the surface of the agar medium in the dish, thus completing the microbial sampling. After sampling, the operator can cultivate the microorganisms in the petri dish, allowing them to determine the type, concentration, and degree of contamination based on the cultivation data, facilitating subsequent processing. This process is repeated after sampler body 1 has been used. Afterwards, the baffle 6 can be rotated again, allowing the positioning block 7 on the baffle 6 to slide into the positioning groove 8 on the mounting frame 3. At this time, the locking block 9 on the positioning block 7 will move to the position of the locking groove 10, allowing the locking block 9 to be elastically engaged in the locking groove 10, thereby fixing the positioning block 7 in the positioning groove 8. At this time, the sealing ring 11 on the baffle 6 will also move to the position of the sealing groove 12, allowing the sealing ring 11 to also be engaged in the sealing groove 12, ensuring the sealing between the baffle 6 and the mounting frame 3. At this time, the baffle 6 and the mounting frame 3 can block and protect the exhaust port 2, effectively preventing dust or debris in the environment from entering the sampler body 1 through the exhaust port 2, and avoiding the accumulation of dust and debris in the sampler body 1, which would affect the operation of the components.

[0035] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
