[0028] Example 1

[0029] Reference Figures 1 to 7 This embodiment provides a homogenizing device for microbial testing, including a test tube 100. A homogenizing mechanism 200 is provided on the top of the test tube 100. The homogenizing mechanism 200 includes a cap 201, a turntable 202, a pressing platform 203, and a stirring roller 204. The cap 201 is threaded to the end of the test tube 100. A central groove 201a is provided through the axial center of the outer wall of the cap 201. The turntable 202 is rotatably connected to the top of the outer wall of the cap 201. The pressing platform 203 is rotatably connected to the top of the central groove 201a of the cap 201. The stirring roller 204 is rotatably connected to the bottom of the outer wall of the pressing platform 203.

[0030] A connecting rod 203a is fixedly connected to the bottom of the pressing platform 203. The stirring roller 204 is sleeved with the connecting rod 203a. Several sets of stirring blades 204b are provided on the outer wall of the roller 204. Several sets of spiral grooves 201a-1 are opened on the inner wall of the shaft groove 201a. A slider 204a is provided on the top of the outer wall of the stirring roller 204. The slider 204a is slidably connected inside the several sets of spiral grooves 201a-1. Several sets of rotating grooves 201b are fixedly connected to the outer wall of the stirring roller 204. The up and down sliding of the cap 201 drives the stirring roller 204 to slide synchronously. Because the slider 204a slides inside the spiral grooves 201a-1, the stirring roller 204 rotates during the up and down sliding process. The rotation of the stirring roller 204 drives the stirring blades 204b to stir the slurry inside the test tube 100.

[0031] The top of the cap 201 is provided with a rotating groove 201b, and the bottom of the turntable 202 is provided with a rotating block 202b. Both the rotating groove 201b and the rotating block 202b are annular. The rotating block 202b rotates inside the rotating groove 201b. The top of the turntable 202 is provided with a pressing groove 202a, and the pressing table 203 slides up and down inside the pressing groove 202a of the turntable 202. The rotation of the rotating block 202b and the rotating groove 201b allows the cap 201 and the turntable 202 to rotate coaxially.

[0032] The top of the pressing platform 203 has a third flow port 203a-1, which passes through the pressing platform 203 and the connecting rod 203a. The bottom of the outer wall of the connecting rod 203a has a rotating hole A203a-2, and the bottom of the outer wall of the stirring roller 204 has a hole 204c. Under normal conditions, the rotating hole A203a-2 and 204c are not connected. When the cap 201 is pressed, the cap 201 drives the stirring roller 204 to slide downward and rotate the stirring roller 204 to its limit position. At this time, 204c is connected to the rotating hole A203a-2. At this time, the air inside the test tube 100 can flow out through 204c, the rotating hole A203a-2, and the third flow port 203a-1.

[0033] The top of the cap 201 has a first flow port 201c, and the top of the outer wall of the turntable 202 has a second flow port 202c. Under normal conditions, the second flow port 202c and the first flow port 201c are not connected. When the cap 201 is rotated, the second flow port 202c will be connected to the first flow port 201c. At this time, the slurry inside the test tube 100 will flow out through the first flow port 201c and the second flow port 202c in sequence.

[0034] The outer wall of the cap 201 has limiting grooves A201d and B201d-1 of different depths. The bottom of the outer wall of the pressing platform 203 is provided with a limiting pin 203b, which slides within the limiting grooves A201d and B201d-1. The depth of limiting groove A201d is greater than that of limiting groove B201d-1. Due to the setting of the limiting pin 203b, under normal conditions, the pressing platform 203 cannot be pressed because of the limiting pin 203b. However, when the pressing platform 203 is rotated, the limiting pin 201d-1 moves freely. When 3b is aligned with the limiting groove A201d or the limiting groove B201d-1, the pressing table 203 can be pressed. When the limiting pin 203b is aligned with the limiting groove A201d, the pressing table 203 can be fully pressed, and the rotating holes A203a-2 and 204c can be connected. When the limiting pin 203b is aligned with the limiting groove B201d-1, the pressing table 203 cannot be fully pressed, and the stirring roller 204 cannot rotate to the limit position, thus preventing the rotating holes A203a-2 and 204c from being connected.

[0035] A return spring is fixedly connected to the bottom of the outer wall of the pressing platform 203 at the connecting rod 203a. The other end of the return spring contacts the top of the cap 201. The function of the return spring is that when the pressing platform 203 is pressed, the return spring contracts. When the pressing platform 203 is released, it provides elastic force to make the pressing platform 203 return to its original position.

[0036] Working principle: Under normal conditions, the second flow port 202c is not connected to the first flow port 201c, and the third flow port 203a-1, rotating holes A203a-2, and 204c are not connected. At this time, the interior of the test tube 100 is completely closed. When it is necessary to stir the slurry inside the test tube 100, the rotating table 202 is rotated so that the pressure groove 202a can expose the limiting groove B201d-1, and the limiting groove B201d-1 is aligned with the limiting pin 203b. Then, the pressing table 203 is pressed, and the pressing table 203 presses... The sliding mechanism inside the groove 202a drives the stirring roller 204 to slide up and down. As the stirring roller 204 slides up and down inside the axial groove 201a, the sliding of the slider 204a inside the spiral groove 201a-1 causes the stirring roller 204 to rotate simultaneously. This rotation of the stirring roller 204 drives the stirring blade 204b, thereby stirring the slurry inside the test tube 100. When it is necessary to remove a small amount of slurry from the test tube 100 without removing the lid, the turntable 202 is rotated, causing the pressure groove 202 to... a) can expose the limiting groove A201d and align the limiting pin 203b with the limiting groove A201d. In this state, the second flow port 202c is connected to the first flow port 201c. The test tube 100 can be inverted. Since the slurry inside the test tube 100 has only a single outlet, the internal air pressure cannot change, making it difficult for the slurry inside the test tube 100 to flow out easily. Then, the pressing table 203 is fully pressed. The pressing table 203 slides inside the pressing groove 202a, thereby driving the stirring roller 204 to rotate. When the... After full pressing, the stirring roller 204 rotates to its limit position, and the rotating holes A203a-2 and 204c are in a connected state. In this state, since the test tube 100 is in an inverted state, the air inside the test tube 100 and 204c are at the same end of the test tube 100. At this time, the air inside the test tube 100 can be discharged in sequence through 204c, rotating hole A203a-2 and third flow port 203a-1, so that the slurry inside the test tube 100 can flow out in sequence through the first flow port 201c and the second flow port 202c.
