[0007] Further, the two sampling rods have a gap in the left-right direction; and the bottom end edge of the sampling rod is arc-shaped.

[0008] Further, a weight is fixedly connected to the end of the sampling rod away from the hinged part; by arranging the weight, the two sampling rods can be restored to the state of the inner sides being in close contact under the action of gravity after sampling.

[0009] Further, a stirring blade is fixedly connected to the outside of the sampling rod.

[0010] Furthermore, flocking cotton is provided on the inner side of the sampling rod.

[0011] The utility model is provided with two rotatable sampling rods, which take up less space when placed in the sampling bottle and consume less eluent; and the stirring blades are provided, which can rotate along with the connecting rod to stir the eluent, so that microorganisms can quickly and fully enter the eluent.

[0019] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0020] Example 1

[0021] like Figures 1 to 3 As shown, an environmental and food microorganism sampling device includes a sampling bottle 1, a bottle cap 2 detachably connected to the sampling bottle 1, and a connecting rod 3 fixedly connected to the bottom of the bottle cap 2. The bottom of the connecting rod 3 is provided with a mounting groove 301, and two sampling rods 4 are hinged in the mounting groove 301 through two hinge shafts 7. The two sampling rods 4 can rotate to the left and right sides respectively; the mounting groove 301 can limit the sampling rod 4 when the sampling rod 4 is rotated to a position perpendicular to it.

[0022] The two sampling rods 4 have a gap in the left-right direction; the bottom end edges of the sampling rods 4 are arc-shaped.

[0023] The inner side surfaces of the sampling rods 4 are provided with flocking cotton; the flocking cotton is used to collect microorganisms.

[0024] By arranging two rotatable sampling rods 4, the sampling rods 4 occupy a smaller space in the sampling bottle and consume less eluent.

[0025] Embodiment 2

[0026] As shown in Figure 4 Embodiment 2 also provides an environmental and food microorganism sampling device, which is different from the environmental and food microorganism sampling device in Embodiment 1 only in that a weight 5 is fixedly connected to the end of the sampling rod 4 away from the hinge; by arranging the weight 5, the two sampling rods 4 are restored to the state of abutting the inner side surfaces under the action of gravity after sampling.

[0027] Embodiment 3

[0028] As shown in Figure 5 Embodiment 3 also provides an environmental and food microorganism sampling device, which is different from the environmental and food microorganism sampling device in Embodiment 2 only in that an agitating blade 6 is fixedly connected to the outer side of the sampling rod 4; by arranging the agitating blade 6, the agitating blade 6 can rotate with the connecting rod 3 and agitate the eluent, so that the microorganisms enter the eluent quickly and sufficiently.

[0029] The working principle of the above embodiments is as follows:

[0030] During sampling, the bottle cap 2 is held to take out the connecting rod 3 from the sampling bottle 1 and to be above the object to be sampled; then the connecting rod 3 is pressed downward, so that the two sampling rods 4 are separated until the two sampling rods 4 reach the limit of the open state, i.e., the two sampling rods 4 reach the state of being perpendicular to the connecting rod 3; finally, the flocking cotton on the inner side surface of the sampling rod 4 abuts the surface of the object to be sampled, the connecting rod 3 is rotated, and sampling is performed.

[0031] After sampling is completed, the connecting rod 3 is lifted upward, and the two sampling rods 4 are restored to the state of abutting the inner side surfaces; the eluent is added to the sampling bottle 1, the connecting rod 3 is put into the sampling bottle 1, the sampling rod 4 is soaked in the eluent, and the microorganisms on the sampling rod 4 enter the eluent.

[0032] In Embodiment 3, the connecting rod 3 can also be rotated, the connecting rod 3 drives the sampling rod 4 to rotate, the agitating blade on the sampling rod 4 agitates the eluent, so that the microorganisms enter the eluent quickly and sufficiently.

[0033] The above merely describes preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
