[0037] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0038] See also Figure 1-4 The utility model embodiment discloses a cleaning device for a liquid chromatograph injection vial. Figure 1 As shown, a cleaning device for a liquid chromatograph injection vial comprises a fixing seat 2 and a water collecting box 1. The fixing seat 2 is installed at the top box opening of the water collecting box 1 through a plurality of supporting rods 21.

[0039] like Figures 2 to 4 As shown, a rotating disk 3 and a driving unit 4 are provided in the water collecting box 1. The driving unit 4 includes a driving motor 41 installed in the water collecting box 1. A first gear 42 is coaxially connected to the output shaft of the driving motor 41. A second gear 43 is coaxially connected to the rotating disk 3. The first gear 42 is meshed with the second gear 43. The driving motor 41 can drive the rotating disk 3 to rotate via the first gear 42 and the second gear 43.

[0040] The rotating disk 3 is horizontally arranged, and the interior of the rotating disk 3 is hollow. The top of the rotating disk 3 is connected to a plurality of spray heads 31 circumferentially arranged around the axis of the rotating disk 3. The center of the bottom of the rotating disk 3 is connected to a vertically arranged connecting pipe 32. The connecting pipe 32 is connected to the rotating disk 3 by rotating around the axis of the rotating disk 3, and the connecting pipe 32 is connected to the water inlet pipe 81 and the high-pressure air pipe 92.

[0041] A water pump 8 , a high-pressure air pump 9 and a heating box 91 are provided on the outside of the water collecting box 1 . The water pump 8 is connected to the water inlet pipe 81 , and the heating box 91 is connected to the high-pressure air pump 9 and the high-pressure air pipe 92 .

[0042] The fixed seat 2 is provided with a plurality of support seats 22 which are circumferentially arranged around the axis of the rotating disk 3. The support seats 22 are provided with an embedding cavity 221. The support seats 22 are rotatably connected to the fixed seat 2 around their axes, and a driven gear 23 is coaxially connected to the support seat 22. All driven gears 23 are meshed with the same driving gear 24, and the driving gear 24 is coaxially connected to the rotating disk 3.

[0043] Before cleaning the sample bottle, the mouth of the sample bottle will be first inserted upside down into the embedding cavity 221 to keep the sample bottle stable; then the water pump 8, the high-pressure air pump 9 and the driving motor 41 will be started, the water pump 8 will introduce water into the connecting pipe 32 through the water inlet pipe 81, and the high-pressure air pump 9 will introduce high-pressure gas into the connecting pipe 32 through the high-pressure air pipe 92, the water and the high-pressure gas will collide with each other and enter the spray head 31 through the inside of the rotating disk 3, and the spray head 31 will spray high-pressure water mist upward; the driving motor 41 will drive the rotating disk 3 to rotate, and the rotating disk 3 will drive the driven gear 23 and the support seat 22 to rotate through the driving gear 24, so that the high-pressure water mist can be sprayed to any position inside any sample bottle, thereby achieving comprehensive cleaning of the inside of the sample bottle, and the water inside the sample bottle will directly flow downward into the water collecting box 1 for collection.

[0044] After the sample bottle is cleaned, the water pump 8 will be turned off and the heating box 91 will be turned on. The high-pressure gas ejected by the high-pressure air pump 9 will be heated by the heating box 91 and then ejected into the sample bottle through the spray head 31, so that the sample bottle can be quickly dried so that the sample bottle can be quickly put into use next time.

[0045] It is worth noting that when the heated high-pressure gas is ejected, the residual water inside the connecting pipe 32, the rotating disk 3 and the spray head 31 will be pushed out by the high-pressure gas to prevent the device from breeding bacteria due to moisture due to long-term non-use.

[0046] The bottom of the water collecting box 1 is connected to a drain pipe 11 , and an opening and closing valve 12 is installed on the drain pipe 11 so that the waste water in the water collecting box 1 can be discharged.

[0047] One-way valves 82 are installed on both the water inlet pipe 81 and the high-pressure gas pipe 92, so that water and high-pressure gas can only flow in one direction.

[0048] like Figure 1 and Figure 2As shown, a loading unit 5 is provided on the left and right sides of the water collecting box 1, and the loading unit 5 includes a first bracket 51, and the first bracket 51 is rotatably connected to a first rotating frame 52 that can be flipped on a vertical plane, and a first reduction motor 53 is installed on the first bracket 51, and the output shaft of the first reduction motor 53 is connected to the first rotating frame 52; a first electric cylinder 54 is installed on the first rotating frame 52, and a first mounting seat 55 is installed on the piston rod of the first electric cylinder 54, and a plurality of first clamping seats 56 are installed on the first mounting seat 55.

[0049] During the cleaning of the first batch of sample bottles, the worker can place the second batch of sample bottles on the first clamping seat 56 of the first mounting seat 55 and insert the bottom of the sample bottles into the first clamping seat 56, thereby preparing the sample bottles in advance.

[0050] After the first batch of sample bottles are unloaded, the first reduction motor 53 will drive the first rotating frame 52 to flip, so that the first mounting seat 55 moves to the top of the fixed seat 2. At this time, the bottom of the sample bottle will be clamped in the first clamping seat 56, so that the sample bottle will not fall down; then the first electric cylinder 54 will drive the first mounting seat 55 to move linearly, so that the first clamping seat 56 pushes the bottle mouth of the sample bottle down and inserts it into the embedding cavity 221.

[0051] It is worth noting that the clamping force of the embedded cavity 221 on the sample bottle is greater than the clamping force of the first clamping seat 56 on the sample bottle. When the first clamping seat 56 rises away from the fixed seat 2, the bottom of the sample bottle will be separated from the first clamping seat 56, so that the second batch of sample bottles can be quickly loaded into the corresponding embedded cavity 221.

[0052] like Figure 1 As shown, a feeding unit 6 is provided on the right side of the water collecting box 1, and the feeding unit 6 includes a second bracket 61, and a second rotating frame 62 which can be flipped on a vertical plane is rotatably connected to the second bracket 61, and a second reduction motor 63 is installed on the second bracket 61, and the output shaft of the second reduction motor 63 is connected to the second rotating frame 62; a second electric cylinder 64 is installed on the second rotating frame 62, and a second mounting seat 65 is installed on the piston rod of the second electric cylinder 64, and a plurality of second clamping seats 66 are installed on the second mounting seat 65.

[0053] When the sample bottle is cleaned and dried, the second reduction motor 63 will drive the second rotating frame 62 to flip, so that the second mounting seat 65 moves to just above the fixed seat 2; then the second electric cylinder 64 will drive the second mounting seat 65 to move linearly, so that the bottom of the sample bottle is inserted into the second clamping seat 66.

[0054] It is worth noting that the clamping force of the embedded cavity 221 on the sample bottle is smaller than the clamping force of the second clamping seat 66 on the sample bottle. When the second clamping seat 66 rises away from the fixed seat 2, the second clamping seat 66 will drive the sample bottle to rise synchronously, so that the bottle mouth of the sample bottle is separated from the embedded cavity 221; then the second reduction motor 63 will drive the second rotating frame 62 to flip and reset, thereby realizing the rapid unloading of the sample bottles, so that the next batch of sample bottles can be quickly cleaned in this application.

[0055] like Figure 2 and Figure 3 As shown, a liquid flow meter 83 is installed on the water inlet pipe 81, a gas flow meter 93 is installed on the high-pressure gas pipe 92, and an infrared sensor 57 is installed on the first bracket 51; the first rotating frame 52 and the second rotating frame 62 are of different sizes, so that the infrared sensor 57 can only detect the first mounting seat 55 flipped to the top of the fixed seat 2, but cannot detect the second mounting seat 65 flipped to the top of the fixed seat 2.

[0056] like Figure 1 As shown, it also includes a controller 7, a liquid flow meter 83, a gas flow meter 93, a water pump 8, a high-pressure air pump 9, a heating box 91, a drive motor 41, an infrared sensor 57, a first electric cylinder 54, a first reduction motor 53, a second reduction motor 63 and a second electric cylinder 64 are all coupled to the controller 7.

[0057] The working principle of the utility model is as follows: during the cleaning process of the sample bottle, the worker first places the sample bottle on the first clamping seat 56 of the first mounting seat 55, so that the bottom of the sample bottle is embedded in the first clamping seat 56; then the controller 7 will control the first reduction motor 53 and the first electric cylinder 54 to start, so that the first mounting seat 55 is turned over to the top of the fixed seat 2, and the first electric cylinder 54 will drive the first mounting seat 55 to descend, so that the first clamping seat 56 pushes the sample bottle into the embedding cavity 221, thereby realizing the automatic loading of the sample bottle; at this time, the infrared sensor 57 will detect the first mounting seat 55 and transmit a cleaning signal to the controller 7, and the controller 7 will first control the first electric cylinder 54 and the first reduction motor 53 to move, so that the first rotating frame 52 and the first rotating frame 52 are ... The mounting seat 55 moves to reset, and then controls the driving motor 41, the water pump 8 and the high-pressure air pump 9 to start; the driving motor 41 will drive the rotating disk 3 to rotate through the first gear 42 and the second gear 43, the rotating disk 3 will drive the supporting seat 22 to rotate through the driving gear 24 and the driven gear 23, the water pump 8 will pass water into the connecting pipe 32 through the water inlet pipe 81, and the high-pressure air pump 9 will pass high-pressure gas into the connecting pipe 32 through the high-pressure gas pipe 92. The water and the high-pressure gas will collide with each other and enter the spray head 31 through the inside of the rotating disk 3. The spray head 31 will spray high-pressure water mist at various positions inside each sample bottle, thereby achieving comprehensive cleaning of the inside of the sample bottle. The water inside the sample bottle will directly flow downward into the water collecting box 1 for collection.

[0058] When the liquid flow meter 83 detects that the liquid flow reaches the specified value, it means that the sample bottle has been cleaned. The liquid flow meter 83 will send a drying signal to the controller 7. The controller 7 will control the water pump 8 to turn off, the heating box 91 to turn on, and the liquid flow meter 83 to return to zero. The high-pressure gas sprayed by the high-pressure air pump 9 will be heated by the heating box 91 and then sprayed into the sample bottle through the spray head 31, so that the sample bottle can be quickly dried.

[0059] When the gas flow meter 93 detects that the gas flow reaches the specified value, it means that the sample bottle has been dried. The gas flow meter 93 will send a material unloading signal to the controller 7. The controller 7 will control the drive motor 41 to turn off, the high-pressure air pump 9 to turn off, the heating box 91 to turn off, and the gas flow meter 93 to return to zero. The controller 7 will also control the second reduction motor 63 and the second electric cylinder 64 to move. The second reduction motor 63 will drive the second rotating frame 62 to flip, so that the second mounting seat 65 moves to the top of the fixed seat 2. The second electric cylinder 64 will drive the second mounting seat 65 to descend, so that the bottom of the sample bottle is inserted into the second clamping seat 66. Then the second electric cylinder 64 will drive the second mounting seat 65 to rise, and the second reduction motor 63 will drive the second rotating frame 62 to flip, so that the second mounting seat 65 moves to reset, thereby realizing the unloading of the sample bottle.

[0060] To summarize, workers only need to place the sample bottles to be cleaned in the first clamping seat 56, and the present application can automatically complete the loading, cleaning, drying and unloading of the sample bottles, so that the sample bottles can be quickly put into use next time; during the cleaning process of the sample bottles, workers can prepare the next batch of sample bottles to be cleaned in the first clamping seat 56, so that the present application can quickly clean the next batch of sample bottles.
