Description

Technical Field

[0001] This utility model relates to the field of sampling device technology, and in particular to a sampling device for the production and processing of cleaning agents. Background Technology

[0002] Cleaning agents are formulated with surfactants and various additives. When washing dirt off the surface of an object, they reduce the surface tension of the aqueous solution and improve the cleaning effect. In order to ensure the stability and consistency of product quality, it is necessary to regularly sample and test the semi-finished and finished cleaning agents at different stages during the production and processing of cleaning agents.

[0003] The most common sampling device currently available is the syringe-type sampling device, which mainly consists of a syringe, a needle, a collection tube, and a matching piston assembly. By controlling the piston assembly to move back and forth inside the syringe, the cleaning agent can be sampled into the collection tube. However, when multiple samplings are required, time must be spent before each sampling to remove the previously obtained sample from the collection tube before sampling can be performed again, which is a rather cumbersome process. Utility Model Content

[0004] The purpose of this invention is to address the following shortcomings in the prior art: when multiple samplings are required, time must be spent removing the previously obtained sample from the collection tube before sampling can be performed again, which is a rather cumbersome process. Therefore, this invention proposes a sampling device for the production and processing of cleaning agents.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sampling device for the production and processing of cleaning agents includes a mounting rod, a circular block fixedly mounted on the bottom of the mounting rod, a first sampling chamber formed inside the circular block, a second sampling chamber vertically connected to the first sampling chamber formed at the top of the mounting rod, a piston rod slidably inserted and sealed inside the second sampling chamber, four liquid outlets formed in a circumferential shape on the side wall of the circular block, a liquid inlet formed at the bottom of the circular block, an inlet pipe fixedly mounted on the bottom of the circular block for covering the inlet, multiple liquid outlet pipes fixedly mounted in a circumferential shape on the side wall of the circular block, one end of each of the multiple liquid outlet pipes covering the multiple liquid outlets, and a one-way valve provided in both the liquid outlet pipes and the liquid inlet pipe.

[0007] The first sampling chamber has a rotating ring installed in a sealed rotatable manner on its cavity wall. The surface of the rotating ring has a liquid inlet. An installation ring is fixedly installed at the bottom of the rotating ring. The opening of the installation ring corresponds to the position of the liquid inlet. Multiple sliding rods are fixedly installed in a circumferential shape on the upper surface of the installation ring. The piston rod is slidably sleeved on the multiple sliding rods. A transparent collection tube is fixedly installed at the end of the liquid outlet tube away from the circular block.

[0008] Preferably, the one-way valve in the outlet pipe is open from the first sampling chamber and the second sampling chamber to the collection pipe, and the one-way valve in the inlet pipe is open from the outside to the first sampling chamber and the second sampling chamber.

[0009] Preferably, the top end of the slide rod has a partial thread, and a nut is threaded onto the top end of the slide rod.

[0010] Preferably, a cap is threaded onto the top of the collection tube, and the surface of the cap is provided with anti-slip texture.

[0011] Preferably, a fixing ring is fixedly sleeved at the top of the piston rod, and a spring rod is vertically fixedly installed on the lower surface of the fixing ring. The upper surface of the circular block has four slots for inserting the bottom end of the spring rod in a circumferential shape. The four slots correspond to the positions of multiple liquid outlets, and the spring rod corresponds to the position of the liquid inlet.

[0012] Preferably, a lifting ring is fixedly sleeved on the spring rod, and a rubber pad is adhered to the surface of the lifting ring.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By coordinating the circular block, rotating ring, and piston rod, multiple samples of cleaning agent can be sequentially loaded into multiple collection tubes, avoiding the tedious step of removing previously obtained samples from the collection tubes before each sampling.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0025] Reference Figures 1-7 A sampling device for cleaning agent production and processing includes a mounting rod 1, a circular block 2 fixedly mounted at the bottom of the mounting rod 1, a first sampling chamber 3 opened inside the circular block 2, a second sampling chamber 4 vertically opened at the top of the mounting rod 1 and connected to the first sampling chamber 3, a piston rod 5 sealed and slidably inserted inside the second sampling chamber 4, four liquid outlets 6 circumferentially opened on the side wall of the circular block 2, a liquid inlet 7 opened at the bottom of the circular block 2, an inlet pipe 8 fixedly mounted at the bottom of the circular block 2 for covering the liquid inlet 7, multiple liquid outlet pipes 9 circumferentially fixedly mounted on the side wall of the circular block 2, one end of the multiple liquid outlet pipes 9 respectively covering the multiple liquid outlets 6, and a one-way valve is provided in both the liquid outlet pipes 9 and the liquid inlet pipes 8. The conduction direction of the one-way valve in the liquid outlet pipe 9 is from the first sampling chamber 3 and the second sampling chamber 4 to the collection tube 14, and the conduction direction of the one-way valve in the liquid inlet pipe 8 is from the outside to the first sampling chamber 3 and the second sampling chamber 4.

[0026] The first sampling chamber 3 is sealed and rotatably mounted with a rotating ring 10. The surface of the rotating ring 10 is provided with a liquid inlet 11. An installation ring 12 is fixedly installed at the bottom of the rotating ring 10. The ring opening of the installation ring 12 corresponds to the position of the liquid inlet 7. Multiple sliding rods 13 are fixedly installed in a circular shape on the upper surface of the installation ring 12. The piston rod 5 is slidably sleeved on the multiple sliding rods 13. A transparent collection tube 14 is fixedly installed at the end of the liquid outlet tube 9 away from the circular block 2.

[0027] When multiple sampling is required, first, the piston rod 5 is rotated. During this process, multiple sliding rods 13, mounting ring 12, and rotating ring 10 will rotate together until the liquid inlet 11 on the surface of the rotating ring 10 corresponds to one of the liquid outlets 6. At this time, the other three liquid outlets 6 will be covered by the surface of the rotating ring 10. Then, the inlet tube 8 is inserted into the cleaning agent to be sampled. Then, the piston rod 5 is moved upward. At this time, the volume of the space between the bottom end of the piston rod 5 and the bottom of the first sampling chamber 3 will increase, and the pressure will decrease. The cleaning agent will then enter the first sampling chamber 3 and the second sampling chamber 4 from the inlet tube 8. Then, the piston rod 5 is moved downward. At this time, the volume of the space between the bottom end of the piston rod 5 and the bottom of the first sampling chamber 3 will decrease, and the pressure will increase. The cleaning agent located in the first sampling chamber 3 and the second sampling chamber 4 will then enter the collection tube 14 connected to the liquid outlet 6 connected to the liquid inlet 11.

[0028] Then, the inlet tube 8 is moved to the next sampling location. The piston rod 5 is then rotated so that the rotating ring 10 rotates until the position of the inlet 11 corresponds to that of another outlet 6. At this point, the other three outlets 6 are covered by the rotating ring 10. The piston rod 5 is then controlled to move vertically back and forth to deliver the cleaning agent in this area to another outlet tube 9 from the outlet 6 corresponding to the position of the inlet 11. The cleaning agent is then loaded into another collection tube 14. This process is repeated to load cleaning agent samples from multiple samplings into multiple collection tubes 14 in sequence, avoiding the tedious step of removing the previously obtained samples from the collection tube 14 before each sampling.

[0029] The top end of the slide rod 13 has a partial thread, and a nut 15 is threaded onto the top end of the slide rod 13. The nut 15 can prevent the piston rod 5 from separating from the mounting rod 1.

[0030] A cap 16 is threaded onto the top of the collection tube 14. The surface of the cap 16 has anti-slip texture. When the collection tube 14 is filled with cleaning agent, the cap 16 can be threaded onto the top of the collection tube 14 to seal the top of the collection tube 14 and prevent the collected cleaning agent sample from spilling out.

[0031] A retaining ring 17 is fixedly sleeved at the top of the piston rod 5. A spring rod 18 is vertically fixedly installed on the lower surface of the retaining ring 17. The upper surface of the circular block 2 has four slots 19 in a circumferential shape for inserting the bottom end of the spring rod 18. The four slots 19 correspond to the positions of multiple liquid outlets 6, and the spring rod 18 corresponds to the position of the liquid inlet 11.

[0032] When the piston rod 5 is rotated to control the position of the liquid inlet 11 on the surface of the rotating ring 10 to correspond with the position of one of the liquid outlets 6, the bottom end of the spring rod 18 will correspond with the position of one of the slots 19. Then, the bottom end of the spring rod 18 is inserted into the slot 19, which restricts the rotation of the piston rod 5 and prevents the piston rod 5 from rotating during vertical movement, causing the liquid inlet 11 to no longer correspond with the position of the liquid outlet 6.

[0033] A lifting ring 20 is fixedly sleeved on the spring rod 18. A rubber pad is adhered to the surface of the lifting ring 20. By controlling the upward movement of the lifting ring 20, the spring rod 18 can be retracted, allowing the bottom end of the spring rod 18 to move out of the slot 19, which is convenient and quick.

[0034] In this invention, when multiple samplings are required, the piston rod 5 is first rotated. During this process, multiple sliding rods 13, mounting ring 12, and rotating ring 10 rotate together until the liquid inlet 11 on the surface of the rotating ring 10 aligns with one of the liquid outlets 6. At this point, the other three liquid outlets 6 are covered by the surface of the rotating ring 10. Then, the inlet tube 8 is inserted into the cleaning agent to be sampled. Next, the piston rod 5 is moved upward, and the cleaning agent enters the first sampling chamber 3 and the second sampling chamber 4 from the inlet tube 8. Then, the piston rod 5 is moved downward, and the cleaning agent in the first sampling chamber 3 and the second sampling chamber 4 enters the liquid outlet 6 connected to the liquid inlet 11. The sample is placed in the connected collection tube 14, and then the inlet tube 8 is moved to the next sampling location. The piston rod 5 is then rotated so that the rotating ring 10 rotates until the position of the inlet 11 corresponds to the position of another outlet 6. At this time, the other three outlets 6 will be covered by the rotating ring 10. Then, the piston rod 5 is controlled to move vertically back and forth to transport the cleaning agent in this area to another outlet tube 9 from the outlet 6 corresponding to the position of the inlet 11, and then fill it into another collection tube 14. This process is repeated to fill multiple collection tubes 14 with cleaning agent samples taken multiple times, avoiding the cumbersome step of taking the previously obtained sample out of the collection tube 14 before each sampling.

[0035] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
