DETAILED DESCRIPTION

[0031] The following description is merely a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0032] A device for preparing oral liquid containing Chinese medicinal ingredients, such as Figure 1 and Figure 2 As shown, it includes a first mounting frame 1, a stirring tank 2, a liquid guide tube 3, a driving motor 4, a stirring rod 5, a liquid collection cylinder 6, a sampling mechanism 7 and a lifting mechanism 8. The first mounting frame 1 is connected to the stirring tank 2, and the stirring tank 2 is used to prepare the Chinese medicine oral liquid. The upper sides of the left and right parts of the stirring tank 2 are connected to the liquid guide tube 3. The top of the stirring tank 2 is connected to the driving motor 4 by bolts. The output shaft of the driving motor 4 is connected to the stirring rod 5. The stirring rod 5 is used to stir the prepared Chinese medicine oral liquid. The front part of the stirring tank 2 is connected to the liquid collection cylinder 6. The liquid collection cylinder 6 can facilitate people to extract the medicinal liquid in the stirring tank 2. The sampling cylinder 71 is provided with a sampling mechanism 7 for quickly extracting and deriving the medicinal liquid. The first mounting frame 1 is provided with a lifting mechanism 8 for lifting the sampling mechanism 7.

[0033] In the process of preparing the Chinese medicine oral liquid, it is necessary to continuously sample and test the oral liquid to determine whether the ratio meets the standard. First, in the process of preparation, it is necessary to start the drive motor 4. The output shaft of the drive motor 4 drives the stirring rod 5 to rotate, thereby stirring the Chinese medicine oral liquid in the stirring tank 2. After stirring, the drive motor 4 is turned off, and then the oral liquid in the sampling cylinder 71 is sampled by the sampling mechanism 7. The sampling mechanism 7 is then lifted by the lifting mechanism 8 for easy taking. After the sampling test is completed, the lifting mechanism 8 is controlled to reset, thereby resetting the sampling mechanism 7. In summary, the oral liquid in the liquid taking cylinder 6 is quickly taken out by the sampling mechanism 7, which improves the sampling efficiency and makes sampling more convenient.

[0034] like Figure 1 、 Figure 3 、 Figure 4 and Figure 5As shown, the sampling mechanism 7 includes a sampling cylinder 71, a baffle 72 and a turntable 73. The top of the liquid taking cylinder 6 is rotatably connected to a turntable 73, and another turntable 73 is clamped on the turntable 73. The turntable 73 is provided with anti-skid patterns to avoid the situation of hand slipping when rotating the turntable 73. There is damping between the turntable 73 on the lower side and the liquid taking cylinder 6, which can make the turntable 73 rotate more stably. There are three guide grooves 74 on the turntable 73. Three baffles 72 are connected, and the baffles 72 are all slidably connected to the guide groove 74 on the lower side. A sampling cylinder 71 is clamped on the turntable 73 on the upper side. The sampling cylinder 71 is used to sample the oral liquid of Chinese medicine. The sampling cylinder 71 is also slidably connected to three baffles 72, and the three baffles 72 are all slidably connected to the guide groove 74 on the upper side. The baffles 72 are all used to block the liquid. Rotating the turntable 73 can make the baffles 72 slide and close to each other.

[0035] The hopper 72 is then rotated to the left of the hopper 73 and the hopper 73 is rotated to the right of the hopper 73. The hopper 72 is rotated to the right of the hopper 73 and the hopper 73 is rotated to the left of the hopper 73. The hopper 72 is rotated to the right of the hopper 73 and the hopper 73 is rotated to the right of the hopper 73.

[0036] like Figure 1 、 Figure 6 and Figure 7As shown, the lifting mechanism 8 comprises a fixed frame 81, a lifting frame 82, a first spring 83, a sliding block 84, a second spring 85 and a dial block 86. The front side of the mixing tank 2 is connected to the fixed frame 81, and the lifting frame 82 is slidably connected to the fixed frame 81. The lifting frame 82 can push the sampling tube 71. Three first springs 83 are connected between the lifting frame 82 and the fixed frame 81. The first springs 83 are all wound around the fixed frame 81, and the tops of the first springs 83 are all connected to the fixed frame 81. The first springs 83 are The bottom ends of the two levers 83 are connected to the lifting frame 82. The left part of the fixed frame 81 is slidably connected to a sliding block 84. The sliding block 84 can limit the position of the lifting frame 82. A second spring 85 is connected between the sliding block 84 and the fixed frame 81. The front end of the second spring 85 is connected to the fixed frame 81, and the rear end of the second spring 85 is connected to the sliding block 84. The reset force of the second spring 85 is relatively small. The left side of the upper turntable 73 is connected to a shift block 86. The shift block 86 can push the sliding block 84.

[0037] As the turntable 73 rotates counterclockwise, it will drive the dial block 86 to move counterclockwise, thereby squeezing and pushing the sliding block 84. As the sliding block 84 is pushed forward, the second spring 85 will be compressed. At this time, the sliding block 84 no longer limits the lifting frame 82. In the initial state, the first spring 83 is in a stressed and stretched state. When the lifting frame 82 is no longer limited, under the action of the first spring 83, the lifting frame 82 will slide upward, thereby pushing the sampling tube 71 upward, achieving the effect of automatically sending the sampling tube 71 out, thereby facilitating the detection personnel to start rapid detection. Since the reset force of the second spring 85 is small, it will not drive the sliding block 84 to push the turntable. The first spring 83 is applied to the lifting frame 82 to push the sampling tube 71 upwards and reset it, thereby forcing the lifting frame 82 to slide downwards and reset. The first spring 83 is stretched and then reset as the turntable 73 rotates clockwise to reset. At this time, the sliding block 84 is no longer squeezed. Under the action of the second spring 85, the sliding block 84 will slide backward and reset, and the lifting frame 82 is engaged and limited. In summary, the rotation of the turntable 73 drives the shift block 86 to move, so that the sliding block 84 no longer limits the lifting frame 82. Under the action of the first spring 83, the lifting frame 82 automatically slides upwards and resets, thereby causing the sampling tube 71 to automatically move upwards and lift, thereby automatically delivering the sampling tube 71.

[0038] like Figure 1 and Figure 8As shown, an adjustment mechanism 9 is also included. The adjustment mechanism 9 includes a second mounting bracket 91, an adjustment bracket 92 and a latch 93. The second mounting bracket 91 is slidably connected to the sampling tube 71, and the adjustment bracket 92 is threadedly connected to the second mounting bracket 91. The adjustment bracket 92 can accurately adjust the sampling height. A positioning hole 94 is opened on the front side of the sampling tube 71, and a latch 93 is slidably connected to the second mounting bracket 91. The latch 93 can be engaged with the positioning hole 94. Through the cooperation between the latch 93 and the positioning hole 94, the sampling height can be preliminarily adjusted.

[0039] When sampling Chinese medicine oral liquid, the amount of sampling can be adjusted to avoid excessive sampling and waste of raw materials. First, the latch 93 is pulled forward to disengage the latch 93 from the positioning hole 94, and then the second mounting bracket 91 is pulled upward, so that the adjustment bracket 92 moves upward to complete the preliminary adjustment of the sampling height. Then, the latch 93 is pushed backward to engage with the positioning hole 94 and reset. By rotating the adjustment bracket 92, the adjustment bracket 92 is continuously moved upward, and the sampling height is accurately adjusted. Repeating the above operation can continuously adjust the sampling height, which is convenient for the tester to perform quantitative sampling and testing. After the quantitative test is completed, the second mounting bracket 91 is pulled upward After the test is completed, the second mounting bracket 91 is put back in its original position, and the adjusting bracket 92 is rotated in the opposite direction to make the adjusting bracket 92 move downward and reset. Then the latch 93 is pulled forward to disengage the latch 93 from the positioning hole 94, and then the second mounting bracket 91 is pushed downward and reset. Finally, the latch 93 is pushed backward to engage with the positioning hole 94 and reset. In summary, the position of the second mounting bracket 91 is adjusted to achieve a preliminary adjustment of the sampling height, and then the adjusting bracket 92 is rotated to move the adjusting bracket 92, thereby achieving precise adjustment of the sampling height, thereby achieving the effect of facilitating quantitative testing by the testing personnel.

[0040] like Figure 1 and Figure 9 As shown, it also includes a supporting mechanism 10, which includes a first connecting rod 101, a connecting frame 102, a fixing member 103 and a second connecting rod 104. The connecting frame 102 is connected to the sampling cylinder 71, and the connecting frame 102 is used to stabilize the sampling cylinder 71. The left and right sides of the connecting frame 102 are rotatably connected to the first connecting rod 101, and the upper front side of the first mounting frame 1 is connected to the left and right symmetrical fixing members 103, and the fixing members 103 are rotatably connected to the second connecting rod 104. The second connecting rod 104 on the left is rotatably connected to the first connecting rod 101 on the left, and the second connecting rod 104 on the right is also rotatably connected to the first connecting rod 101 on the right. The first connecting rod 101 and the second connecting rod 104 cooperate with each other to adjust the angle of the connecting frame 102, thereby facilitating the discharge of the oral liquid in the sampling cylinder 71.

[0041] When the lifting frame 82 lifts the sampling cylinder 71 upward and pushes it out, the first connecting rod 101 will rotate. At this time, the sampling cylinder 71 can remain stable under the cooperation of the first connecting rod 101 and the connecting frame 102, and will not overturn or tip over. Then, by pulling the sampling cylinder 71, the first connecting rod 101 and the second connecting rod 104 are both rotated, thereby taking out the sampling cylinder 71 and pouring out the oral liquid in the sampling cylinder 71 for testing. Then, the sampling cylinder 71 is pushed backward to move back to its original position, so that the first connecting rod 101 and the second connecting rod 104 are both rotated to reset, and finally the sampling cylinder 71 is inserted back into the turntable 73. In summary, through the cooperation between the first connecting rod 101 and the connecting frame 102, the sampling cylinder 71 can be prevented from tipping over when it is pushed upward. Then, with the cooperation of the first connecting rod 101 and the second connecting rod 104, the angle of the sampling cylinder 71 can be adjusted, thereby facilitating the pouring out and testing of the oral liquid in the sampling cylinder 71.

[0042] like Figure 1 and Figure 10 As shown, it also includes a placement mechanism 11, which includes a placement frame 111 and a fixing seat 112. Two fixing seats 112 are connected to the upper front side of the first mounting frame 1, and the fixing seats 112 are rotatably connected to the placement frame 111. The placement frame 111 can be snapped into the second mounting frame 91 to place the second mounting frame 91.

[0043] After the second mounting frame 91 is pulled out, the second mounting frame 91 can be snap-connected with the placement frame 111 to place the second mounting frame 91 to avoid contamination caused by placing the second mounting frame 91 on the desktop. After the inspection is completed, the second mounting frame 91 can be detached from the placement frame 111.

[0044] like Figure 1 and Figure 11 As shown, it also includes a flow regulating mechanism 12, which includes a feed pipe 121 and a throttle valve 122. The top of the liquid guide tube 3 is connected to the feed pipe 121, and the feed pipe 121 is rotatably connected to the throttle valve 122. The throttle valve 122 is used to throttle the guide tube, and a rotating part is provided on the top of the throttle valve 122 to facilitate people to rotate the throttle valve 122.

[0045] When adding Chinese medicine oral liquid raw materials into the mixing tank 2, the feed pipe 121 can be connected to an external device, and then the raw materials can be introduced into the mixing tank 2 through the feed pipe 121. When there is enough oral liquid raw materials in the mixing tank 2, the throttle valve 122 is turned so that the feed pipe 121 cannot feed the materials. When it is necessary to continue adding raw materials, the throttle valve 122 is turned so that the feed pipe 121 is no longer blocked and throttled.

[0046] While the present disclosure has been described with respect to only a limited number of embodiments, those skilled in the art, having benefit of this disclosure, will appreciate that numerous other embodiments can be devised without departing from the scope of the invention. Accordingly, the scope of the present invention should be limited only by the claims appended hereto.
