[0023] In order to make it easier to understand the structure of the present invention and the functional features and advantages that can be achieved, the preferred embodiments of the present invention are described in detail with reference to the drawings as follows:

[0024] Example:

[0025] like Figures 1 to 4 As shown, the utility model provides a portable foam meter for rapid determination, including a test tube 1, a burette 2 and a shell 3 for placing the test tube 1 and the burette 2. The side wall of the shell 3 is slidably connected with a pull-out plate 31 for placing the test tube 1 and the burette 2 outside the shell 3, so that the test tube 1 and the burette 2 are easy to test. It usually also includes a motor for rotating the liquid in the test tube 1 to generate foam, and other miniature cameras for detecting changes in foam in the test tube 1. The miniature camera can be connected to the pull-out plate 31, and the motor is also connected to the pull-out plate 31, or a space for placing other components separately is extended from the bottom of the shell 3. The bottom end of the test tube 1 is generally provided with a switch valve, which is closed during the test and opened after the test to discharge the flushed liquid.

[0026] The side wall of the housing 3 is provided with a slideway 32, and a slide rail 311 is fixedly connected to the side of the pull-out plate 31 close to the housing 3, and the slide rail 311 slides in the slideway 32. A fixed plate 33 is fixedly connected in the housing 3, and the fixed plate 33 partially separates the pull-out plate 31, and the burette 2 is located on the side of the fixed plate 33 away from the ground, and the test tube 1 is located on the side of the fixed plate 33 close to the ground. Due to the fragility of the test tube 1, the test tube 1 is placed alone on the side of the fixed plate 33 close to the ground, and the pull-out plate 31 is divided into two parts, upper and lower, by the fixed plate 33, but the two parts of the pull-out plate 31 are not completely disconnected, and the fixed plate 33 can be additionally provided with a limit plate at the edge to prevent the pull-out plate 31 from sliding out of the housing 3. The top of the housing 3 is fixedly connected or hinged with a handle. One side of the housing 3 is provided with an opening and closing plate, and the pull-out plate 31 is pulled out after opening, and a buckle for closing and locking the opening and closing plate is hinged or fixedly connected on the opening and closing plate.

[0027] As another example, Figure 2 and Figure 3As shown, the side of the pull-out plate 31 of the present application away from the housing 3 is fixedly connected with a clamping mechanism 4 for clamping the test tube 1. The clamping mechanism 4 includes an elastic telescopic rod 41 and a clamping plate 42, one end of the elastic telescopic rod 41 is fixedly connected to the side of the pull-out plate 31 away from the housing 3, and the other end of the elastic telescopic rod 41 is fixedly connected to the clamping plate 42, and the clamping plate 42 is clamped on the outer wall of the test tube 1. The side of the clamping plate 42 in contact with the test tube 1 is fixedly connected with a rubber pad 421. The elastic telescopic rod 41 is a telescopic rod with a spring arranged inside, and the elastic telescopic rod 41 pushes the clamping plate 42 to apply pressure to the test tube 1, reducing the shaking amplitude of the test tube 1 during carrying, and the rubber pad 421 reduces the hard pressure on the test tube 1, reducing the probability of its damage during carrying. In addition, the test tube 1 can extend to the outside of the housing 3 with the pull-out plate 31, which is convenient for testing or experiments.

[0028] The bottom wall of the housing 3 is fixedly connected with a fixing sleeve 34 for receiving the test tube 1. The fixing sleeve 34 and the bottom wall of the housing 3 are connected by a vertical rod or the like, or the fixing sleeve 34 can also be fixed to the back plate of the housing 3. After the test tube 1 completes the experiment or test, the test tube 1 is inserted into the fixing sleeve 34 to further reduce the shaking amplitude of the test tube 1 during carrying.

[0029] As another example, Figures 4 to 6 As shown, the housing 3 of the present application is provided with a locking mechanism 5 for fixing the pull-out plate 31, and the locking mechanism 5 is movably connected to the pull-out plate 31. The locking mechanism 5 includes a plug plate 51, a socket 52, a slot 53 and a latch 54, the plug plate 51 is fixedly connected to the pull-out plate 31, the slot 53 is arranged on the back plate of the housing 3, the plug plate 51 is inserted in the slot 53, the socket 52 is arranged on the plug plate 51, and the latch 54 is inserted in the socket 52 so as to be movably connected to the plug plate 51.

The end of the latch 54 for inserting the socket 52 is fixedly connected with a convex strip 541, and the latch 54 and the convex strip 541 are interference fit with the socket 52. The plug plate 51 and the latch 54 are both provided with two or more, so as to have high stability. The convex strip 541 is a rubber strip, which can effectively reduce the probability of the pin 54 falling off during carrying. When in use, the pin 54 is pulled out from the socket 52, and the pull-out plate 31 can be pulled out. After use, the pull-out plate 31 is retracted and the pin 54 is inserted into the socket 52.

[0030] As another example, Figure 1 and Figure 4As shown, a cleaning mechanism 6 for cleaning the test tube 1 is fixedly connected in the housing 3 of the present application. The cleaning mechanism 6 includes a liquid storage tank 61, a hard tube 62 and a hose 63. The liquid storage tank 61 is fixedly connected to the side of the fixed plate 33 away from the ground, one end of the hard tube 62 is fixedly connected and communicated with the liquid storage tank 61, and the other end of the hard tube 62 is fixedly connected and communicated with the hose 63. A micro water pump can be added to the connection between the liquid storage tank 61 and the hard tube 62 to flush the liquid in the liquid storage tank 61 into the test tube 1. The liquid in the liquid storage tank 61 is generally distilled water. The hose 63 aligns the tube mouth with the tube mouth of the test tube 1 to facilitate flushing.

[0031] As another example, Figure 2 As shown, the present application pull-out plate 31 is fixedly connected with a horizontal plate 71 on the side of the fixed plate 33 away from the ground, and the horizontal plate 71 is rotatably connected with a folding rod 72 on the side close to the fixed plate 33, and the folding rod 72 is fixedly connected with a collar 73 on the side away from the horizontal plate 71, and the burette 2 is movably sleeved in the collar 73. Since the horizontal plate 71 is fixedly connected with the pull-out plate 31, when testing, after the pull-out plate 31 is pulled out, the burette 2 is also pulled out, and the burette 2 is closer to the inside of the housing 3 than the test tube 1. During the test, the burette 2 can be taken out from the collar 73, and after absorbing the measured object, it is placed on the collar 73, and the folding rod 72 is rotated to place the burette 2 just above the test tube 1, and the sample can be added to the test tube 1 by squeezing the burette 2. Due to the support of the collar 73, the angle of titration is more vertical to the test tube 1, which effectively improves the test effect. The burette 2 after absorbing the analyte may also be directly placed on the collar 73 to drop the analyte directly into the test tube 1 .

[0032] The present application discloses a portable foam meter for rapid determination. The working principle is as follows: when in use, the opening and closing plate of the housing 3 is opened, the latch 54 is pulled out from the socket 52, the test tube 1 is taken out from the fixed sleeve 34, and the pull-out plate 31 is pulled out from the housing 3 to the edge of the fixed plate 33. The test tube 1 is placed between the clamps 42. Due to the pressure of the elastic telescopic rod 41 and the rubber pad 421 on the clamp 42, the test tube 1 can be clamped. After the test tube 1 is placed, the burette 2 is taken out to absorb the object to be measured, the burette 2 is placed on the ring 73, the folding rod 72 is rotated so that the ring 73 is located directly above the test tube 1, and the burette 2 is squeezed to drip the object to be measured into the test tube 1 for testing. If necessary, a motor can be added to the lower end of the test tube 1 to drive the liquid in the test tube 1 to produce foam, or the test tube 1 can be directly shaken instead. After the test is finished, align the hose 63 with the mouth of the test tube 1, open the water pump or switch valve of the liquid storage tank 61, flush the distilled water in the liquid storage tank 61 into the test tube 1, and flush the foam out of the test tube 1. After completion, push the pull plate 31 back, insert the latch 54 into the socket 52 to lock it, and close the opening and closing plate of the housing 3 and buckle it.
