[0027] like Figure 1 As shown, a liquid-phase injection bottle cleaning device comprises a cleaning rack 1, the cleaning rack 1 comprises a well plate 11 and a bottom plate 12, the well plate 11 is movably arranged on the bottom plate 12, a plurality of placement holes 111 are opened on the well plate 11, each liquid-phase injection bottle (not shown in the figure) is respectively inverted in the placement hole 111, a plurality of liquid spraying pipes 121 are arranged on the bottom plate 12, the liquid outlet end of the liquid spraying pipe 121 extends into the placement hole 111, and the liquid spraying pipe 121 corresponds to the placement hole 111 one by one;

[0028] The pump body 2 has one end connected to the cleaning liquid storage container 3 through a connecting pipe 21, and the other end connected to the liquid spraying pipe 121 through a delivery pipe 22, so that: the cleaning liquid in the cleaning liquid storage container 3 is transported to the liquid spraying pipe 121 via the pump body 2, and the liquid spraying pipe 121 extends into the liquid injection bottle inverted in the placement hole 111 to spray cleaning liquid for cleaning.

[0029] The cleaning rack 1 of the present scheme is composed of a well plate 11 and a bottom plate 12. The well plate 11 is provided with a placement hole 111 for storing a liquid-phase injection bottle. The liquid-phase injection bottle is placed in the placement hole 111 with its bottom facing up. A liquid-phase injection bottle is placed in each placement hole 111 (here, since the bottle body diameter of the liquid-phase injection bottle is slightly larger than the inner diameter of the placement hole 111, it can be stuck in the placement hole 111 without falling; and the diameter from the bottleneck to the bottle mouth of the liquid-phase injection bottle is smaller than the inner diameter of the placement hole 111, so the bottle mouth of the liquid-phase injection bottle can extend to the lower end of the placement hole 111 for easy cleaning). In this way, it is easy to clean and also easy to discharge waste liquid; There is a protruding liquid spray pipe 121, each liquid spray pipe 121 corresponds to a placement hole 111 equipped with a liquid phase injection bottle, and the liquid spray pipe 121 extends into the placement hole 111. When a liquid phase injection bottle is placed in the placement hole 111, the liquid spray pipe 121 extends into the liquid phase injection bottle. Since the liquid spray pipe 121 is connected to the cleaning liquid storage container 3 through the pump body 2, the pump body 2 transports the cleaning liquid to the liquid spray pipe 121, and the cleaning liquid is sprayed out by the liquid spray pipe 121, and the used liquid phase injection bottle is high-pressure washed. The waste liquid after washing directly flows downward from the inverted liquid phase injection bottle, and the waste liquid flows out while washing. The liquid phase injection bottle is easy to clean and saves more cleaning liquid. The entire liquid phase injection bottle cleaning device has a simple structure and is easy to assemble, occupies a small space, and is particularly suitable for use in laboratories.

[0030] The orifice plate 11 of the present solution is movable on the bottom plate 12, that is, the distance between the orifice plate 11 and the bottom plate 12 is adjustable, and the distance between the corresponding liquid spray pipe 121 and the placement hole 111 is adjustable, which is convenient for cleaning liquid injection bottles of various lengths and has a wider range of applications.

[0031] Furthermore, the cleaning rack 1 further comprises a top cover 13, which is arranged on the orifice plate 11, and a plurality of top blocks 131 are arranged at the bottom of the top cover 13, and the top blocks 131 correspond to the placement holes 111 one by one, so that the bottom of the liquid injection bottle inverted in the placement hole 111 abuts against the top blocks 131. The top blocks 131 of this solution are mostly made of flexible material and will not damage the liquid injection bottle.

[0032] The arrangement of the top cover 13 enables the cleaning rack 1 to form a relatively closed cleaning space, which is not easily disturbed by the outside world, and the cleaning liquid is not easy to seep out / splash to the outside. The bottom of the top cover 13 has a plurality of top blocks 131, and the top blocks 131 correspond to the number of the placement holes 111 and the liquid phase injection bottles. During cleaning, the top blocks 131 are pressed against the bottom of the liquid phase injection bottle to prevent the liquid phase injection bottle from shifting when being washed with high pressure, so that the liquid phase injection bottle is stably placed in the placement hole 111, ensuring the smooth cleaning of the liquid phase injection bottle.

[0033] Furthermore, a plurality of liquid outlet holes 1211 are provided at the top of the liquid spraying pipe 121. Figure 2 As shown, a plurality of small liquid outlet holes 1211 are opened on the tube wall at the top of the liquid spraying tube 121, that is, both the tube opening at the top of the liquid spraying tube 121 and the liquid outlet holes 1211 on the tube wall can spray cleaning liquid, so the cleaning effect is better.

[0034] Furthermore, the top cover 13, the orifice plate 11 and the four corners of the bottom plate 12 are connected by screws 4; each of the screws 4 is threadedly connected with a first nut 41, a second nut 42, a third nut 43 and a fourth nut 44, the first nut 41 is located at the lower end of the bottom plate 12 and abuts therewith, the second nut 42 is located at the upper end of the bottom plate 12 and abuts therewith, the third nut 43 is located above the second nut 42, and the top end of the third nut 43 abuts against the orifice plate 11, and the fourth nut 44 is located at the upper end of the orifice plate 11 and abuts therewith.

[0035] like Figure 3As shown, in this embodiment, the distance between the orifice plate 11 and the bottom plate 12 is adjusted by the cooperation of the screw rod 4 and four nuts. The screw rod 4 is a long screw rod 4 with a relatively long length. The top cover 13, the orifice plate 11 and the four corners of the bottom plate 12 are provided with screw holes, and the screw rod 4 passes through the screw holes to connect the top cover 13, the orifice plate 11 and the bottom plate 12. The first nut 41, the second nut 42, the third nut 43, and the fourth nut 44 are all screwed onto the screw rod 4 and can be screwed on the screw rod 4. The diameter of the nut is significantly larger than the diameter of the mounting hole 5 for mounting the screw rod 4 at the four corners of the top cover 13, the orifice plate 11, and the bottom plate 12. The first nut 41 and the second nut 42 are respectively located above and below the bottom plate 12 to fix the position of the bottom plate 12. The third nut 43 and the fourth nut 44 are respectively located below and above the orifice plate 11. The position of the orifice plate 11 can be adjusted by screwing the third nut 43 and the fourth nut 44. Of course, the first nut 41 and the second nut 42 can also be screwed to adjust the position of the bottom plate 12 when necessary. Thus, the distance between the orifice plate 11 and the bottom plate 12 is adjustable, which can be adapted to the cleaning of liquid-phase injection bottles of various heights.

[0036] The top cover 13 and the screw rod 4 can also be positioned by two nuts.

[0037] Furthermore, the upper surface of the bottom plate 12 is recessed from the edge to the middle to form an inclined liquid guide plate 122, and a through drainage channel 123 is provided in the middle of the bottom plate 12. The upper surface of the bottom plate 12 is gradually recessed along the diagonal line toward its center point to form an inclined liquid guide plate 122, and a drainage channel 123 is provided in the middle of the bottom plate 12. The drainage channel 123 runs through the entire bottom plate 12, and the waste liquid generated when cleaning the liquid phase injection bottle can flow out to the outside through the drainage channel 123.

[0038] Furthermore, the device also includes a waste liquid collection container (not shown in the figure), which is connected to the drainage channel 123. A waste liquid collection container for receiving cleaning waste liquid can be placed below the drainage channel 123, and the collected waste liquid can be recycled after treatment, which is more energy-saving and environmentally friendly. When the waste liquid collection container is not set, the liquid phase injection bottle cleaning device of this scheme can be directly placed in a wastewater pool for cleaning.

[0039] Furthermore, the delivery pipe 22 includes a main pipe 221 and a plurality of branch pipes 222 . The main pipe 221 is connected to each of the branch pipes 222 . Each of the branch pipes 222 is connected to one of the liquid spray pipes 121 . A switch valve is disposed on each of the branch pipes 222 .

[0040] The branch pipe 222 in this embodiment can be a hose, and each spray pipe 121 and the main pipe 221 of the delivery pipe 22 are connected by multiple branch pipes 222. Since a switch valve is provided on the branch pipe 222 (it can also be a water-stop clamp in actual use), when the number of liquid phase injection bottles during cleaning is significantly less than the spray pipe 121, the water-stop clamp / switch valve can be used to clamp the excess branch pipe 222, and the spray pipe 121 corresponding to the branch pipe 222 will not spray out cleaning liquid, thereby avoiding waste of cleaning liquid.

[0041] Furthermore, a hot air pump is included, and the hot air pump is used to dry the cleaned liquid-phase injection bottle, and the hot air pump is connected to the delivery pipe 22. After the liquid-phase injection bottle is cleaned, since the inlet of the delivery pipe 22 can also be connected to the hot air pump, the hot air pump blows out hot air to quickly dry the cleaned liquid-phase injection bottle, so as to facilitate the reuse of the liquid-phase injection bottle.

[0042] Furthermore, the pump body 2 is an acid- and alkali-resistant pump, and the connecting pipe 21 and the delivery pipe 22 are made of any one of polyvinyl chloride, polypropylene or polytetrafluoroethylene. The pump body 2 of this solution is not a high-pressure water pump, but a booster pump of an acid- and alkali-resistant pump. Similarly, the connecting pipe 21 and the delivery pipe 22 are also made of materials resistant to organic reagents and acids and alkalis, such as polyvinyl chloride, polypropylene or polytetrafluoroethylene, to ensure that the liquid-phase injection bottle cleaning device can be used for a long time.

[0043] The method of using the liquid-phase injection bottle cleaning device of the present invention is as follows: 1. Use a hose (branch pipe 222) to connect the liquid inlet of each spray pipe 121 at the bottom plate 12 and the liquid outlet of the delivery pipe 22, take four first nuts 41 and screw them on the bottom of the four screw rods 4 respectively, the first nuts 41 are at the same height of the screw rods 4, insert the four screw rods 4 with the nuts screwed from the bottom of the mounting hole 5 of the bottom plate 12 and pass them out to the top of the bottom plate 12, screw a second nut 42 on each part of the screw rod 4 to fix the bottom plate 12 and the screw rod 4, and then screw a third nut 43 on each screw rod 4, the height of each nut is the same; install the four corners of the orifice plate 11 The installation holes 5 are passed through the screw rods 4, and the third nut 43 (or other nuts) are adjusted to make the liquid injection pipe 121 extend into the placement hole 111 of the orifice plate 11, and the liquid injection bottle to be cleaned is placed upside down in the orifice plate 11, and the nut is adjusted to make the liquid injection pipe 121 in the liquid injection bottle and keep a certain distance from the bottom of the liquid injection bottle, and then the fourth nut 44 is screwed on the screw rod 4 to fix the orifice plate 11, and the installation holes at the four corners of the top cover 13 are passed through the screw rods 4, so that the top block 131 at the bottom of the top cover 13 contacts the bottom of the liquid injection bottle, and then a nut is screwed on each screw rod 4 on the top cover 13 to fix the top cover 13. The top cover 13, the orifice plate 11, and the bottom plate 12 are connected by the screw rods 4, and the bottom ends of the four screw rods 4 are in the same plane, so the whole set of cleaning device can be supported to stand upright on any horizontal table or wastewater tank.

[0044] 2. Place a waste liquid collection container under the drainage channel 123 at the center of the bottom plate 12, connect the cleaning liquid storage container 3 to the pump body 2 with the connecting pipe 21, and connect the pressure pump to the spray pipe 121 with the delivery pipe 22.

[0045] 3. Start the pump body 2 and adjust the power. The cleaning liquid will be sprayed out from the nozzle of the liquid spray pipe 121 and the liquid outlet hole 1211 of the tube wall to perform high-pressure cleaning on each liquid phase injection bottle on the orifice plate 11.

[0046] 4. After cleaning, remove the nuts and hoses.

[0047] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
