Description

Technical Field

[0001] The utility model relates to the field of sampling, in particular to a microbial sampling device. Background Art

[0002] A microbial sampling device is a device used to collect microbial samples from air, liquid or surfaces, and is widely used in fields such as medical treatment, food, and pharmaceuticals.

[0003] When performing microbial sampling, the two-way pump inside the housing can be started by pressing a button on the housing, so that air is sucked into the housing. Then the air passes through the filter screen at the upper end of the housing and reaches the culture dish inside the housing for microbial sampling. After sampling, the filter screen is removed and the internal culture dish is taken out. After multiple uses, the filter screen becomes blocked, resulting in a decrease in the sampling flow rate. Currently, in order to save the cost of replacing the filter screen, the two-way pump is used to blow air in the reverse direction to flush the blocked filter screen (by reverse flushing, the debris adhered to the filter screen is separated from the filter screen, enabling the filter screen to be reused to reduce the usage cost). However, the filter screen is only lapped on the upper end of the housing, and during reverse flushing, the filter screen is easily detached from the housing, affecting the cleaning effect. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is that the filter screen is only lapped on the upper end of the housing, and during reverse flushing, the filter screen is easily detached from the housing, affecting the cleaning effect.

A two-way pump for sucking air into the housing is provided inside the housing. A plurality of buttons are provided on one side of the housing. A filter screen is provided on one side of the housing. A culture dish is provided on one side of the housing close to the filter screen. A reinforcement device is provided on one side of the housing by means of the mounting component, and the reinforcement device fixes the position of the filter screen.

[0006] The effects achieved by the above components are: when performing microbial sampling, the two-way pump inside the housing can be started by pressing a button on the housing, so that air is sucked into the housing. Then the air passes through the filter screen at the upper end of the housing and then reaches the culture dish inside the housing for microbial sampling. After sampling, the filter screen is removed and the internal culture dish is taken out. When cleaning the filter screen, the culture dish is taken out and the two-way pump blows air in the reverse direction (that is, the fan blades of the two-way pump rotate in the reverse direction), so that the debris adhered to the filter screen is separated from the filter screen, enabling the filter screen to be reused to reduce the usage cost. At this time, the reinforcement device reinforces the position of the filter screen to prevent the filter screen from detaching from the housing.

[0011] Preferably, a limiting rod is fixedly connected to one side of the placement rack, and one side of the limiting rod is slidably connected to the moving plate.

[0012] The effects achieved by the above components are as follows: By using the limiting rod, the movement trajectory of the placement rack is limited, making the moving plate move more stably.

[0013] Preferably, a rubber pad is fixedly connected to one side of the reinforcement plate, and the size of the rubber pad is adapted to the size of the reinforcement plate.

[0014] The effects achieved by the above components are as follows: By using the rubber pad, the friction between the reinforcement plate and the filter screen is increased, enabling the reinforcement plate to better fix the filter screen.

[0015] Preferably, a guiding plate is fixedly connected to one side of the reinforcement plate, and the guiding plate is inclined on one side of the reinforcement plate.

[0032] Figures 1 to 4 A microbial sampling device shown includes a housing 1 and a mounting assembly 3. A plurality of buttons 4 are provided on one side of the housing 1. A filter screen 5 is provided on one side of the housing 1. The filter screen 5 is lapped on the upper end of the housing 1. A culture dish 6 is provided on the side of the housing 1 close to the filter screen 5. A reinforcement device 2 is provided on one side of the housing 1 by means of the mounting assembly 3. The reinforcement device 2 fixes the position of the filter screen 5. When performing microbial sampling, by the edge of the filter screen 5, the filter screen 5 is moved so that the filter screen 5 is lapped and placed on the upper end of the housing 1, and the filter screen 5 is located above the culture dish 6. Then, the two-way pump inside the housing 1 can be started through the buttons 4 on the housing 1, so that air is sucked into the housing 1. Then the air passes through the filter screen 5 on the upper end of the housing 1 and then reaches the culture dish 6 inside the housing 1 for microbial sampling. After the sampling is completed, the filter screen 5 is taken away and the internal culture dish 6 is taken out. When cleaning the filter screen 5, the culture dish 6 is taken out and the two-way pump blows air in the reverse direction, so that the sundries adhered to the filter screen 5 are separated from the filter screen 5, enabling the filter screen 5 to be reused to reduce the use cost. At this time, the reinforcement device 2 reinforces the position of the filter screen 5 to prevent the filter screen 5 from detaching from the housing 1.

[0033] Figures 1 to 4The shown reinforcement device 2 includes a placement rack 21. One side of the placement rack 21 is rotatably connected to a threaded rod 22. One side of the threaded rod 22 is fixedly connected to an operation block 23. Opposite threads are provided on both sides of the threaded rod 22. Moving plates 24 are threadedly connected to both sides of the threaded rod 22. One side of the moving plate 24 is fixedly connected to a reinforcement plate 25. When cleaning the filter net 5, the operation block 23 can be rotated to make the threaded rod 22 rotate on the placement rack 21, and then rotated to make the moving plates 24 on both sides of the threaded rod 22 approach each other. Then the moving plate 24 drives the reinforcement plate 25 to contact the filter net 5, and then abuts and fixes the filter net 5, thereby completing the fixation and reinforcement of the position of the filter net 5. By using the reinforcement device 2, the position of the filter net 5 can be fixed, avoiding the situation that the filter net 5 is easily separated from the housing 1 when the filter net 5 is blown and cleaned, which may affect the use of the filter net 5, and thus improving the use effect of the microbial sampling device.

[0034] Figures 1 to 4 One side of the shown operation block 23 is fixedly connected with a number of anti-slip blocks 26, and the number of anti-slip blocks 26 are arranged at equal intervals on one side of the operation block 23. By using the anti-slip blocks 26, the friction between the operation block 23 and the operator is increased, making it easier for the operator to rotate the operation block 23. One side of the placement rack 21 is fixedly connected with a limiting rod 27, and one side of the limiting rod 27 is slidably connected to the moving plate 24. By using the limiting rod 27, the moving track of the placement rack 21 is limited, making the moving plate 24 move more stably. One side of the reinforcement plate 25 is fixedly connected with a rubber pad 28, and the size of the rubber pad 28 is adapted to the size of the reinforcement plate 25. By using the rubber pad 28, the friction between the reinforcement plate 25 and the filter net 5 is increased, enabling the reinforcement plate 25 to better fix the filter net 5 (where the reinforcement plate 25 is clamped between the side and the top of the filter net 5). One side of the reinforcement plate 25 is fixedly connected with a guiding plate 29, and the guiding plate 29 is inclined on one side of the reinforcement plate 25. By using the guiding plate 29, one side of the reinforcement plate 25 can more easily be positioned above the filter net 5, thus improving the use effect of the reinforcement plate 25.

[0035] Figures 1 to 4 The shown installation component 3 includes an installation block 31. One side of the installation block 31 is fixedly connected to the housing 1. A bolt 32 is threadedly inserted into the interior of the installation block 31. One side of the bolt 32 is threadedly connected to the placement rack 21, and a nut 33 is threadedly inserted into one side of the bolt 32. When using the reinforcement device 2, the placement rack 21 can be moved to insert the placement rack 21 into the installation block 31, and then the bolt 32 is rotated to pass through the installation block 31 and fix it to the placement rack 21, and then the nut 33 is rotated to fix the bolt 32. By using the installation component 3, the position of the placement rack 21 can be quickly fixed, facilitating the subsequent use of the reinforcement device 2 by the operator.

[0036] Figures 1 to 4 One side of the shown bolt 32 is threadedly connected with a connecting rope 34, and one side of the connecting rope 34 is threadedly connected with the mounting block 31. By using the connecting rope 34, the bolt 32 is connected to the mounting block 31 to avoid the loss of the bolt 32.

[0037] Working principle: When performing microbial sampling, the two-way pump inside the housing 1 can be started through the button 4 on the housing 1, so that air is inhaled into the housing 1. Then the air passes through the filter screen 5 at the upper end of the housing 1 and then reaches the culture dish 6 inside the housing 1 for microbial sampling. After the sampling is completed, the filter screen 5 is taken away and the internal culture dish 6 is taken out. When cleaning the filter screen 5, the culture dish 6 is taken out and the two-way pump blows air in the reverse direction, so that the sundries adhered to the filter screen 5 are separated from the filter screen 5, and the filter screen 5 can be reused to reduce the use cost. At this time, the reinforcement device 2 reinforces the position of the filter screen 5 to prevent the filter screen 5 from detaching from the housing 1. When cleaning the filter screen 5, the operating block 23 can be rotated to make the threaded rod 22 rotate on the placement rack 21, and then rotated to make the moving plates 24 on both sides of the threaded rod 22 approach each other. Then the moving plate 24 drives the reinforcement plate 25 to contact the filter screen 5, and then the filter screen 5 is abutted and fixed, thus completing the position fixing and reinforcement of the filter screen 5. By using the reinforcement device 2, the position of the filter screen 5 can be fixed, and when the filter screen 5 is cleaned by blowing air, the filter screen 5 is not easily detached from the housing 1, thus preventing the situation that affects the use of the filter screen 5, and further improving the use effect of the microbial sampling device.

[0038] When using the reinforcement device 2, the placement rack 21 can be moved to insert the placement rack 21 into the mounting block 31, and then the bolt 32 is rotated to make the bolt 32 pass through the mounting block 31 and be fixed to the placement rack 21, and then the nut 33 is rotated to fix the bolt 32. By using the mounting component 3, the position of the placement rack 21 can be quickly fixed, so as to facilitate the subsequent use of the reinforcement device 2 by the operator.
