For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] This utility model provides a technical solution:

[0026] Example 1

[0027] Combination Figures 1 to 3 A high-precision airborne bacteria sampling device includes a carrying box (3), with handles (31) rotatably connected to the left and right sides of the carrying box (3), support legs (4) fixedly connected to the bottom of the carrying box (3), an air-pushing mechanism (1) provided inside the carrying box (3), and a sampling mechanism (2) provided inside the bottom of the carrying box (3).

[0028] The air-pushing mechanism (1) includes a driving component (11), a pull-out component (12), and a ventilation component (13). The driving component (11) is located at the top of the carrying case (3), the pull-out component (12) is located at the bottom of the driving component (11), and the ventilation component (13) is located inside the top of the carrying case (3).

[0029] The drive assembly (11) includes an electric cylinder (1101), which is fixedly connected to the top of the carrying case (3). An electric telescopic rod (1102) is fixedly connected to the bottom of the electric cylinder (1101). The electric telescopic rod (1102) is sleeved inside the top of the carrying case (3). The pull-out assembly (12) includes a sealing slide plate (1201), which is fixedly connected to the bottom of the electric telescopic rod (1102). A slide frame (1202) is fixedly connected to the four corners of the outer side of the sealing slide plate (1201). 1202) is slidably connected to the four corners inside the carrying box (3). The sliding block (1203) is fixedly connected to the outside of the sliding block (1202). The sliding block (1203) is slidably connected to the inside of the carrying box (3). The ventilation component (13) includes a sieve plate one (1301). The sieve plate one (1301) is fixedly connected to the top of the carrying box (3) at the position of the outer ring of the electric cylinder (1101). A sieve plate two (1302) is provided below the sieve plate one (1301). The sieve plate two (1302) is fixedly connected to the top of the outer ring of the carrying box (3).

[0030] Furthermore, staff only need to activate the electric cylinder (1101) to drive the sealing slide plate (1201) to move up and down inside the carrying box (3) via the electric telescopic rod (1102). When the device is in use, the up and down movement of the sealing slide plate (1201) completes the suction and discharge of external air, allowing the air in a specific area to come into directional contact with the sampling paper (2202). This enables the device to perform directional sampling of airborne bacteria in a specific area, improving the sampling accuracy of airborne bacteria and reducing the error of the sampling data, making it easier for staff to use.

[0031] Example 2

[0032] See Figure 1 , Figure 2 , Figure 4 and Figure 5Furthermore, based on Embodiment 1, the sampling mechanism (2) is equipped with an installation component (21) and a sampling component (22), wherein the installation component (21) is located inside the bottom of the carrying box (3), and the sampling component (22) is located inside the installation component (21).

[0033] The mounting assembly (21) includes a mounting base (2101), which is fixedly connected to the bottom of the carrying case (3). A panel (2102) is snapped into the mounting base (2101). Threaded rods (2103) are sleeved at the four corners of the panel (2102). The threaded rods (2103) are fixedly connected to the bottom of the carrying case (3). Nuts (2104) are threaded onto the outer ring of the threaded rods (2103). The top of the nuts (2104) fits against the bottom of the panel (2102). The sampling assembly (22) includes a mounting bracket (2201), which is fixedly connected to the panel (2102). At the top, the card holder (2201) is snapped into the bottom of the carrying box (3). A sampling paper (2202) is provided inside the top of the card holder (2201). A cover plate (2203) is provided on the top of the sampling paper (2202). A card protrusion (2204) is fixedly connected to the bottom of the cover plate (2203). Threaded rods (2205) are fixedly connected to the four corners of the bottom of the cover plate (2203). Threaded rods (2205) are snapped into the top of the card holder (2201). Nuts (2206) are threadedly connected to the outer ring of threaded rods (2205). The top of nuts (2206) fits against the top of the card holder (2201).

[0034] Furthermore, staff only need to rotate nut one (2104) and nut two (2206) to complete the disassembly and assembly of the panel (2102) or the cover plate (2203). The operation is simple and convenient for staff to use. At the same time, after the cover plate (2203) is installed, the protrusion (2204) moves downward and cooperates with the top of the card seat (2201) to fix the sampling paper (2202), which increases the stability of fixing the sampling paper (2202) after the cover plate (2203) is installed. It also makes the top opening of the card seat (2201) fit tightly with the sampling paper (2202), which does not guarantee the sampling effect of airborne bacteria in the box (3).

[0035] In actual operation, when this device is used, when it is necessary to sample the air in a designated area, the staff first places the carrying box (3) in the designated area, and then starts the electric cylinder (1101). The electric cylinder (1101) starts and drives the sealing slide plate (1201) to move upward to the top through the electric telescopic rod (1102). The sealing slide plate (1201) moves upward in the carrying box (3) to draw the air in the designated area into the carrying box (3). At this time, the sampling of the air in the designated area is completed.

[0036] Then, the staff placed the sampling paper (2202) flat on the top of the card holder (2201), and then the staff attached the cover plate (2203) to the top of the sampling paper (2202). At this time, the threaded rod two (2205) was attached to the top of the card holder (2201). Then, the staff rotated the nut two (2206) to the threaded rod two (2205) until the top of the nut two (2206) was in contact with the top of the card holder (2201) and could not be rotated anymore. At this time, the fixing of the sampling paper (2202) was completed.

[0037] Then, the staff will attach the card holder (2201) to the bottom of the carrying box (3), so that the panel (2102) is attached to the mounting base (2101) and fits against the bottom of the carrying box (3). At this time, the threaded rod one (2103) is sleeved in the four corners of the panel (2102). Then, the staff will rotate the nut one (2104) to the outer ring of the threaded rod two (2205) until the top of the nut one (2104) fits against the bottom of the carrying box (3) until the nut one (2104) can no longer be rotated. At this time, the installation of the sampling paper (2202) is completed. Finally, the staff will start the electric cylinder (1101) to drive the sealing slide plate (1201) to move downward. At this time, the air in the carrying box (3) will be pushed downward and discharged through the opening at the top of the card holder (2201). During the process of air discharge, it will come into contact with the sampling paper (2202). At this time, the sampling treatment of airborne bacteria in the designated area is completed.

[0038] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
