Abstract
Description
Technical Field
[0001] This utility model relates to the field of airborne bacteria technology, specifically a split-type airborne bacteria sampler. Background Technology
[0002] A planar microbial sampler is an instrument used to sample microbial communities in a specific environment. By analyzing the microbial communities collected by the planar microbial sampler using testing instruments, the types of microbial communities distributed in the environment can be obtained, which provides convenience for scientific research, laboratory production, and other fields.
[0003] In the typical process of collecting airborne bacteria using a sampler, the sampler includes a control device and a collection device, and the sampling and control devices are integrated into one unit to ensure stability during collection. However, when the equipment needs to collect airborne bacteria in a narrow area, if the sampler is moved into the narrow area, the operator cannot control the control device, making it impossible to accurately observe the collection device and thus affecting the sampling effect. Therefore, we propose a split-type airborne bacteria sampler. Utility Model Content
[0004] To address the shortcomings of existing split-type airborne bacteria samplers, this invention provides a split-type airborne bacteria sampler that is mounted on the upper part of a mounting plate via a bracket and fixed by a limiting plate. Depending on the equipment usage requirements, the bracket can be disassembled, meaning the main body of the detection device can be freely replaced, ensuring efficient collection and solving the problems mentioned in the background art.
[0005] This utility model provides the following technical solution: a split-type airborne bacteria sampler, including a base, an mounting plate mounted on the upper part of the base, a bracket movably sleeved inside the side of the mounting plate, a limiting plate for limiting the position of the bracket mounted on the upper part of the mounting plate, a detection device body movably mounted on the top of the bracket, a horizontal plate fixedly connected inside the detection device body, eight sets of sliding rods equally spaced on the upper part of the horizontal plate, a clamping plate movably sleeved inside the sliding rods, an installation sleeve threadedly mounted on the top of the detection device body, and a filter screen mounted inside the installation sleeve.
[0006] Preferably, the limiting plate includes a pull rod, which is movably mounted on the middle of the upper end of the mounting plate. A limiting baffle for limiting the position of the bracket is installed on one side of the mounting plate. A second spring is installed on the side of the limiting baffle. A pull rope is fixedly connected to the middle of the side of the limiting baffle. Both sets of pull ropes are movably sleeved inside the limiting sleeve, and the ends of the pull ropes are fixedly connected to the middle of the pull rod.
[0007] Preferably, a controller is fixedly connected to the lower end of the mounting plate, and the controller has an equipment control device and a display screen installed inside.
[0008] Preferably, a ventilation pipe is fixedly connected to the lower part of the main body of the detection device, and a fan is installed at the lower end of the base. The ventilation pipe enables the base and the main body of the detection device to communicate with each other.
[0009] Preferably, a first spring for applying elastic potential energy is installed at the rear end of the clamping plate, and a culture dish is clamped and installed on the inner side of the clamping plate, with the culture dish positioned at the upper end of the horizontal plate.

[0012] Compared with existing split-type airborne bacteria samplers, this invention has the following advantages:
[0013] 1. This split-type airborne bacteria sampler uses a bracket to limit the position of the main body of the detection device. The bracket can be installed on the upper part of the mounting plate and fixed by a limiting plate, or the bracket can be detached from the outside of the mounting plate and moved freely to different areas.

Detailed Implementation
[0021] 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.
[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A split-type airborne bacteria sampler includes a base 1, with an mounting plate 2 installed on the upper part of the base 1. The mounting plate 2 facilitates the operation and start-up of the device. A bracket 5 is movably sleeved inside the side of the mounting plate 2. The bracket 5 adjusts the position of the main body 6 of the detection device. A limiting plate 8 is installed on the upper part of the mounting plate 2 to limit the position of the bracket 5 inside the mounting plate 2. The main body 6 of the detection device is movably mounted on the top of the bracket 5. A horizontal plate 9 is fixedly connected inside the main body 6. Eight sets of sliding rods 10 are installed at equal intervals on the outer side of the upper end of the horizontal plate 9. A clamping plate 12 is movably sleeved inside the sliding rods 10. The clamping plate 12 compresses and limits the position of the petri dish 13 on the upper part of the horizontal plate 9. An installation sleeve 14 is threadedly sleeved on the top of the main body 6 of the detection device. A filter screen 15 is installed on the inner side of the installation sleeve 14. Rotating the top cover 16 limits the position of the filter screen 15, and the filter screen 15 filters large particulate impurities in the air.
[0023] Please see Figure 3The limiting plate 8 includes a pull rod 81, which is movably mounted in the middle of the upper end of the mounting plate 2. A limiting baffle 82 is installed on one side of the mounting plate 2 to limit the position of the bracket 5. A second spring 83 is installed on the side of the limiting baffle 82. A pull rope 84 is fixedly connected to the middle of the side of the limiting baffle 82. Both sets of pull ropes 84 are movably sleeved inside the limiting sleeve 85. At the same time, the ends of the pull ropes 84 are fixedly connected to the middle of the pull rod 81. In the combined state, the bracket 5 can be installed on the upper part of the mounting plate 2. At the same time, the limiting baffle 82 is elastically supported by the second spring 83. The limit baffle 82 is pushed to engage with the upper part of the bottom of the bracket 5, ensuring the stability of the bracket 5 when it is spliced on the upper part of the mounting plate 2. At the same time, when it is necessary to move the equipment to a narrow area to collect airborne bacteria, the pull rod 81 is pulled, and the pull rod 81 pulls the pull rope 84 to move. The limit sleeve 85 limits the position of the pull rope 84. That is, after the limit baffle 82 is subjected to pressure, it first retracts inward to ensure that the position of the bracket 5 stops and the limit treatment is performed. This ensures that the bracket 5 is more convenient to disassemble from the upper part of the mounting plate 2. At the same time, the bracket 5 can drive the main body 6 of the detection device to move to a narrow area.
[0024] Please see Figure 2 A controller 3 is fixedly connected to the lower end of the mounting plate 2. The controller 3 contains an equipment control device and a display screen. The controller 3 is installed at the lower part of the mounting plate 2. The controller 3 can control the start of the equipment. At the same time, the display screen can observe the status of the airborne bacteria collected inside the petri dish 13.
[0025] Please see Figure 2 A ventilation pipe 7 is fixedly connected to the lower part of the main body 6 of the detection device. A fan 4 is installed at the lower end of the base 1. The ventilation pipe 7 connects the base 1 and the main body 6 of the detection device. By installing the ventilation pipe 7 at the lower end of the main body 6 of the detection device and connecting the ventilation pipe 7 with the base 1, the fan 4 is started. The fan 4 drives the gas to move downward, that is, the fan 4 drives the gas to be transmitted downward to provide power. After the gas is drawn in through the ventilation pipe 7, a negative pressure can be formed inside the main body 6 of the detection device. At this point, the device can collect airborne bacteria.
[0026] Please see Figure 5 The rear end of the clamping plate 12 is equipped with a first spring 11 that applies elastic potential energy. The inner side of the clamping plate 12 holds and installs a culture dish 13. The culture dish 13 is set at the upper end of the horizontal plate 9. Depending on the size of the culture dish 13, after the culture dish 13 is installed on the upper part of the clamping plate 12, the clamping plate 12 moves on the upper part of the slide bar 10 according to the size of the culture dish 13. At the same time, the first spring 11 applies pressure to the clamping plate 12. Thus, the clamping plate 12 can maintain stability when holding the culture dish 13.
[0027] Please see Figure 5The filter screen 15 has filter holes inside and an arc-shaped outer surface. After the filter screen 15 is installed inside the mounting sleeve 14, the gas is drawn in and the filter screen 15 filters out large particles of impurities, so as to avoid the presence of large particles in the airborne bacteria collected inside the petri dish 13, which would affect the collection effect. At the same time, the arc-shaped outer surface of the filter screen 15 effectively drives the impurities to the outside, effectively preventing impurities from adhering to the outside of the filter screen 15 and affecting the gas flow.
[0028] Please see Figure 5 The upper part of the mounting sleeve 14 is threadedly fitted with a top cover 16. The inner side of the top cover 16 is in contact with the outer side of the filter screen 15. The top cover 16 has ventilation holes. After the top cover 16 is installed on the upper part of the mounting sleeve 14, the top cover 16 is rotated and moves downward. That is, the top cover 16 can squeeze and limit the position of the filter screen 15 inside the mounting sleeve 14, and then the top cover 16 can protect the collection device.
[0029] Working principle: When in use, the base 1 is placed on the ground. Depending on the area where impurities need to be collected, the bracket 5 can be placed directly on the upper part of the mounting plate 2. At the same time, the position of the bracket 5 is limited by the limiting plate 8. Alternatively, the bracket 5 can be removed from the inside of the mounting plate 2, and the bracket 5 can move the entire detection device body 6 to different areas. When in use, the petri dish 13 is installed on the inside of the clamping plate 12. At the same time, the fan 4 is turned on. The fan 4 creates a negative pressure state inside the detection device body 6 through the ventilation pipe 7. At the same time, the gas is absorbed through the top cover 16 and filtered by the filter screen 15. Meanwhile, the airborne bacteria in the air can move to the upper part of the petri dish 13, and the gas is discharged from the lower end of the horizontal plate 9, thus completing the collection of airborne bacteria.
[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
