[0028] The utility model will be further described below in conjunction with the accompanying drawings.

[0029] The utility model provides a final cleaning device, which is used for cleaning materials, such as pipe materials 6, using injection water.

[0030] Example 1

[0031] like Figure 1 As shown, the final cleaning device of the present invention comprises a water storage mechanism 2 and a water outlet 1, a water injection port 3, and a piston mechanism 4 respectively connected to the water storage mechanism 2. The water storage mechanism 2 can be, for example, a water storage container such as a water storage tank, a water storage tank, or a water storage barrel, which contains injection water.

[0032] The water outlet 1 and the piston mechanism 4 can be located on both sides of the water storage mechanism 2, so as to facilitate the injection water to flow out of the water outlet 1. There are at least two water outlets 1, so that a plurality of tube materials 6 can be cleaned at the same time with one action of the piston mechanism 4, thereby improving the cleaning effect.

[0033] In addition, the distance between each water outlet 1 is adjustable. For example, an adjustment groove may be provided at the end of the water storage mechanism 2 to adjust the distance between each water outlet 1 so as to adapt to pipe materials 6 of different diameters.

[0034] The piston mechanism 4 is connected to the power mechanism 5. When the power mechanism 5 drives the piston mechanism 4 to push, the water outlet 1 is in an open state and the water injection port 3 is in a closed state; when the piston mechanism 4 performs a return motion, the water outlet 1 is in a closed state and the water injection port 3 is in an open state. In other words, the water outlet 1 is a one-way outlet and the water injection port 3 is a one-way inlet.

[0035] Therefore, when the piston mechanism 4 performs a pushing action to clean the tube material 6, it moves toward the direction close to the water outlet 1, thereby pushing the injection water in the water storage mechanism 2 out of the water outlet 1. Since the piston mechanism 4 is driven by the power mechanism 5, the flow rate of the injection water during cleaning is guaranteed to be stable, avoiding interference from human factors, etc., thereby improving the cleaning effect. At this time, the water injection port 3 is closed, that is, water will not be injected into the water storage mechanism 2 during cleaning, so as to ensure that the volume of the injection water during cleaning is fixed, avoiding interference from human factors, etc., thereby improving the cleaning effect.

[0036] When the piston mechanism 4 is cleaned, the piston mechanism 4 performs a return motion, and moves away from the water outlet 1, and the water injection port 3 is opened, that is, the piston mechanism 4 can simultaneously inject water into the water storage mechanism 2 when performing a return motion. At this time, the water outlet 1 is closed, so the injection water will not flow out from the water outlet 1.

[0037] Specifically, a switch such as a solenoid valve can be set on the water injection port 3, which is linked with the piston mechanism 4. When the piston mechanism 4 advances, the solenoid valve is closed, thereby closing the water injection port 3; when the piston mechanism 4 returns, the solenoid valve is opened, thereby opening the water injection port 3.

[0038] A similar solenoid valve may be provided on the water outlet 1. Alternatively, a pressure switch may be provided on the water outlet 1, which is linked to the piston mechanism 4. When the piston mechanism 4 advances, the pressure increases, and the pressure switch opens, thereby opening the water outlet 1; when the piston mechanism 4 returns, the pressure decreases, and the pressure switch closes, thereby closing the water outlet 1.

[0039] like Figure 2 As shown, the piston mechanism 4 includes a piston rod 42 and a sealing portion 41 disposed on the piston rod 42, and the sealing portion 41 is sealed and connected to the water storage mechanism 2. The sealing portion 41 is made of an elastic material, such as silicone, rubber, etc. The sealing portion 41 forms an interference fit with the water storage mechanism 2 to ensure that the piston mechanism 4 does not leak when in motion.

[0040] like Figure 1 As shown, the final cleaning device of the present invention further includes a power mechanism 5, which may be a cylinder mechanism, an electric cylinder mechanism, a motor, a hydraulic mechanism, etc. The following description will be made by taking a cylinder mechanism as an example.

[0041] Specifically, the power mechanism 5 includes a cylinder 51, an air pipe 52, a switch 53 and a pressure regulating valve 54. The cylinder 51 is connected to the piston mechanism 4, the air pipe 52 is connected to the cylinder 51, and the switch 53 is connected to the air pipe 52 for controlling the start and stop of the cylinder 51. The pressure regulating valve 54 is respectively connected to the switch 53 and the compressed air source.

[0042] The switch 53 is a pneumatic foot switch, so the operator steps on the switch 53 to drive the piston mechanism 4 to perform a pushing action or a returning action.

[0043] Furthermore, the stroke of the cylinder 51 is smaller than the depth of the water storage mechanism 2 , that is, the maximum stroke of the piston mechanism 4 will not exceed the depth of the water storage mechanism 2 , thereby avoiding collision with the inner wall of the water storage mechanism 2 .

[0044] The air pipe 52 is a TPU (thermoplastic polyurethane) air pipe, which has high mechanical strength, good elasticity and wear resistance.

[0045] The final cleaning device of the utility model, when cleaning the inner cavity of the pipe material 6, first connects the pipe material 6 to the water outlet 1, and adjusts the pressure of the compressed gas by adjusting the pressure regulating valve 54 to match the cylinders 51 of different specifications. Then, the switch 53 is stepped on, and the compressed gas is transmitted to the cylinder 51 through the air pipe 52, and the cylinder 51 drives the piston mechanism 4, and the piston mechanism 4 pushes the injection water in the water storage mechanism 2 to be discharged from the water outlet 1 and enter the inner cavity of the cleaning pipe material 6. At this time, the water injection port 3 is in a closed state, thereby completing the flushing of the cleaning pipe material 6.

[0046] When flushing is completed, the cylinder 51 drives the piston mechanism 4 to perform a return motion. At this time, the water outlet 1 is closed, the water inlet 3 is open, and the injection water enters the water storage mechanism 2 from the water inlet 3, completing a lumen flushing process.

[0047] Example 2

[0048] On the basis of the above-mentioned embodiment 1, the final cleaning device provided by the present utility model provides a specific structure of a water outlet 1. The differences between the present embodiment 2 and the above-mentioned embodiment 1 will be described below, and the similarities will not be repeated.

[0049] like Figure 3 and Figure 4 As shown, the water outlet 1 is constructed as the outlet of the cleaning pipe 22. An outer tube 21 is arranged outside the cleaning pipe 22, and a telescopic block 25 is fixed on the outer surface of the outer tube 21. An elastic telescopic member 26 is connected to one side of the telescopic block 25, and the other end of the elastic telescopic member 26 is connected to the water storage mechanism 2. The cleaning pipe 22 can extend into the water storage mechanism 2.

[0050] like Figure 4 As shown, a water spray hole 23 is also provided on the side wall of the cleaning pipe 22, and a brushing portion 24 is also provided between the water spray holes 23 along the axial direction of the cleaning pipe 22. The brushing portion 24 can be, for example, bristles. The brushing portion 24 can be provided on the side wall of the cleaning pipe 22 in an embedded form, or in an outwardly protruding form.

[0051] When cleaning the inner cavity of the tube material 6, the elastic telescopic member 26 can extend the cleaning tube 22 and the outer tube 21 to a suitable position in the inner cavity of the tube material 6, so that the scrubbing portion 24 contacts the inner cavity of the tube material 6, and then the switch 53 is stepped on. At this time, the compressed gas is transmitted to the cylinder 51 through the air pipe 52, and the cylinder 51 drives the piston mechanism 4. The piston mechanism 4 pushes the injection water in the water storage mechanism 2 to be discharged from the water outlet 1 and the water spray hole 23 and enter the inner cavity of the tube material 6. At this time, the water injection port 3 is in a closed state, and the inner cavity of the tube material 6 is doubly cleaned by the water spraying from the water outlet 1 and the water spray hole 23 and the friction of the scrubbing portion 24, thereby achieving a better cleaning effect.

[0052] When flushing is completed, the cylinder 51 drives the piston mechanism 4 to perform a return motion. At this time, the water outlet 1 is closed, the water inlet 3 is open, and the injection water enters the water storage mechanism 2 from the water inlet 3, completing a lumen flushing process.

[0053] Although the present invention has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
