[0002] The cleaning liquid has a good cleaning effect on dirt such as fingerprints and dust adhered to the surface of glass lenses; wide applicability: it can be widely used in the cleaning processes of industries such as optics and metal processing; high stability: it does not volatilize, decompose, or burn, and is safe to use; convenient rinsing: the residual cleaning agent on the surface of the device can be completely rinsed with pure water directly; green and environmentally friendly: it is biodegradable and harmless to the environment. Especially for contact lenses, the contact lens material is special, with a small pore size, weak hydrophilicity, more likely to absorb protein precipitation, and more likely to be wrapped by lipids. Therefore, a special hard lens rinsing liquid is required. However, in the production process of the cleaning liquid, a variety of raw materials need to be mixed. The existing cleaning liquid mixing devices have the technical problem of uneven mixing, so there are defective products in the produced cleaning liquid. Content of the Utility Model

[0003] The utility model provides a mixing device for contact lens cleaning liquid to solve the above technical problems.

[0004] To achieve the above purpose, the utility model is realized through the following technical solutions: A mixing device for contact lens cleaning liquid includes a mixing tank, a rotating shaft, a first spiral blade, and a second spiral blade.

The first spiral blade is wound around the side wall of the rotating shaft. The second spiral blade is wound around the side wall of the rotating shaft. The first spiral blade is located at one end of the rotating shaft close to the top of the mixing tank, and the second spiral blade is located at one end of the rotating shaft close to the bottom of the mixing tank. The spiral directions of the first spiral blade and the second spiral blade are opposite; it further includes a plurality of nozzles, and the plurality of nozzles are installed on the side wall of the rotating shaft. The plurality of nozzles are arranged along the extending direction of the first spiral blade and are staggered with the first spiral blade; a water inlet hole is opened at the top of the mixing tank, and a water inlet channel is opened at one end of the rotating shaft close to the top of the mixing tank. The water inlet channel is communicated with the plurality of nozzles.

[0005] When the mixing device for contact lens cleaning liquid provided by the utility model is in use, first pour the cleaning liquid raw materials into the mixing tank from the feed inlet of the mixing tank, and rotate the rotating shaft to make the first spiral blade and the second spiral blade rotate. Since the spiral directions of the first spiral blade and the second spiral blade are opposite, the cleaning liquid is mixed more evenly under the drive of the first spiral blade and the second spiral blade.

[0006] Optionally, the diameter of the second helical blade is larger than that of the first helical blade.

[0007] Optionally, through holes are formed in the second helical blade.

[0020] Embodiment

[0021] In the production process of the cleaning solution, a variety of raw materials need to be mixed. In the existing cleaning solution mixing device, there is a technical problem of uneven mixing, so there are defective products in the produced cleaning solution.

[0022] To solve the above technical problems, the present embodiment provides a mixing device for a contact lens cleaning solution, which includes a mixing tank 1, a rotating shaft 2, a first helical blade 3 and a second helical blade 4. The mixing tank 1 is provided with a feed inlet and a discharge outlet. The rotating shaft 2 is rotatably installed at the bottom of the mixing tank 1 and is coaxially arranged with the mixing tank 1. The first helical blade 3 is wound around the side wall of the rotating shaft 3. The second helical blade 4 is wound around the side wall of the rotating shaft 3. The first helical blade 3 is located at one end of the rotating shaft 2 close to the top of the mixing tank 1, and the second helical blade 4 is located at one end of the rotating shaft 2 close to the bottom of the mixing tank 1. The rotation directions of the first helical blade 3 and the second helical blade 4 are opposite. A valve is provided at the discharge outlet of the mixing tank 1, and the valve needs to be closed when the mixing tank 1 is working.

[0023] With the above structure, a mixing device for a contact lens cleaning solution provided in this embodiment, when in use, first close the valve at the discharge port, and pour the cleaning solution raw materials into the mixing tank 1 from the feed port of the mixing tank 1. By rotating the rotating shaft 2, the first spiral blade 3 and the second spiral blade 4 are rotated. Since the spiral directions of the first spiral blade 3 and the second spiral blade 4 are opposite, under the drive of the first spiral blade 3 and the second spiral blade 4, the cleaning solution is mixed more evenly.

[0024] On this basis, referring to Figure 3 and Figure 4 As shown, the diameter of the second spiral blade 4 is larger than that of the first spiral blade 3. The first spiral blade 3 makes the liquid in the mixing tank 1 flow towards the bottom of the mixing tank 1, and the second spiral blade 4 drives the liquid in the mixing tank 1 to flow towards the top of the mixing tank 1. Since the second spiral blade 4 is arranged close to the discharge port, and in order to further mix the liquid in the mixing tank 1 more evenly, the diameter of the second spiral blade 4 in this application is larger than that of the first spiral blade 3.

[0025] On this basis, referring to Figure 4 As shown, in order to facilitate the flow of the liquid at the bottom of the mixing tank and thus avoid stratification, through holes are provided on the second spiral blade 4.

[0026] On this basis, referring to Figure 3 and Figure 4 As shown, a mixing device for a contact lens cleaning solution further includes a plurality of nozzles 5. The plurality of nozzles 5 are installed on the side wall of the rotating shaft 2, and the plurality of nozzles 5 are arranged along the extension direction of the first spiral blade 3 and are arranged in an alternating manner with the first spiral blade 3. A water inlet hole is provided at the top of the mixing tank 1, and a water inlet channel 6 is provided at one end of the rotating shaft 2 close to the top of the mixing tank 1. The water inlet channel 6 is communicated with the plurality of nozzles 5. It should be specifically noted that there are multiple types of raw materials for the cleaning solution. In this mixing device for a contact lens cleaning solution in this application, when in use, first pour the base material of the cleaning solution raw materials into the mixing tank 1 through the feed port, and other liquid raw materials enter the water inlet channel 6 through the water inlet hole on the mixing tank 1 and flow into the mixing tank 1 through the nozzles 5, further making the liquid in the mixing tank 1 mixed more evenly.

[0027] On this basis, referring to Figure 1 and Figure 2As shown in the figure, a mixing device for a contact lens cleaning solution further includes a support frame 7, a mounting plate 8, and a driving component 9. The support frame 7 is installed at the bottom of the mixing tank 1. The mounting plate 8 is installed on the support frame 7. The driving component 9 is installed on the mounting plate 8. The output end of the driving component 9 is connected to the rotating shaft 2. By rotating the output end of the driving component 9, the rotating shaft 2 is rotated, thereby driving the first spiral blade 3 and the second spiral blade 4 to rotate and mix the liquid in the mixing tank 1.

[0028] In summary, during the use of a mixing device for a contact lens cleaning solution, first, close the valve at the discharge port, pour the base material of the cleaning solution raw material into the mixing tank 1 through the feed port, and other liquid raw materials enter the water inlet channel 6 through the water inlet holes on the mixing tank 1 and flow into the mixing tank 1 through the nozzle 5. By rotating the output end of the driving component 9, the rotating shaft 2 is rotated, thereby driving the first spiral blade 3 and the second spiral blade 4 to rotate and mix the liquid in the mixing tank 1. In order to facilitate the flow of the liquid at the bottom of the mixing tank, through holes are provided on the second spiral blade 4. At the same time, since the spiral directions of the first spiral blade 3 and the second spiral blade 4 are opposite, under the drive of the first spiral blade 3 and the second spiral blade 4, the cleaning solution is mixed more evenly.

[0029] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope recorded in the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
