Description

Technical Field

[0001] The utility model relates to the technical field of filtration, in particular to a water inlet filtration structure for a vacuum high-pressure cleaning machine. Background Art

[0002] The cleaning machine is used to flush and filter pollutants generated or invaded during the manufacturing, assembly, use and maintenance of the hydraulic system; it can also be used for regular maintenance and filtration of working oil to improve cleanliness, avoid or reduce failures caused by contamination, and thus ensure the high performance, high reliability and long life of hydraulic system equipment.

[0003] When cleaning related equipment, in order to improve the cleaning effect, the cleaning machine usually increases the water pressure at the water outlet. However, if the water at the water inlet is not filtered, the impurities contained in the water will impact the outer wall of the equipment and cause damage to the outer wall of the equipment. In view of this, we propose a water inlet filtration structure for a vacuum high-pressure cleaning machine. Utility Model Content

[0004] In response to the above-mentioned shortcomings of the prior art, the utility model provides a water inlet filtration structure for a vacuum high-pressure cleaning machine, which can effectively solve the problem that the existing cleaning machines usually increase the water pressure at the water outlet, but if the water at the water inlet is not filtered, the impurities contained in the water will impact the outer wall of the equipment, causing damage to the outer wall of the equipment.

[0027] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0028] The present invention will be further described below with reference to the embodiments.

[0029] Example:

[0030] Refer to the attached Figure 1-5 As shown in the figure, a water inlet filtration structure of a vacuum high-pressure cleaning machine includes a box body 100, a cavity 101 is opened inside the box body 100, a circular tube 200 is arranged at the upper part of the box body 100, and the circular tube 200 is connected with the interior of the cavity 101 through two symmetrically arranged connecting tubes 210; and a movable plate 400 movably connected to the interior of the cavity 101 and maintained in a symmetrical arrangement, a filter element 410 is installed in the middle of the two movable plates 400; an output pipe 110 is connected to the cavity 101 in the middle position of the two filter elements 410. Specifically, in the present application, the circular tube 200 is connected to the external water source, and the external water source can be pumped into the cavity 101 opened in the box body 100 through the circular tube 200 through the external pump body. It should be noted that in the present application, the actual filtration is performed using the box body 100. After the filtration is completed, the filtered water is provided through the output pipe 110 provided at the lower side of the box body 100 and connected to the cavity 101, thereby ensuring a stable water supply to the cleaning machine.

[0031] Preferably, when the external pump body guides water through the circular tube 200, the connecting tube 210 and the circular hole 102 into the interior of the cavity 101, a circular hole 102 is provided on the outer wall of the cavity 101, and the circular hole 102 is located on the outer side of the movable plate 400. The connecting tube 210 is installed at the position of the circular hole 102 and remains connected with the cavity 101. Since the circular hole 102 is located on the outer side of the movable plate 400, the water flow with a certain pressure will impact the movable plate 400 and slide in the cavity 101. It should be noted that a limiting groove for limiting the movement of the two movable plates 400 is provided on the inner wall of the cavity 101. The movable plate 400 can only slide in the limiting groove, and when the movable plate 400 contacts the side inner wall of the limiting groove, the capsule 300 located in the middle of the two movable plates 400 is in its original state and is not compressed.

[0032] When water flows from the outside of the movable plate 400 into the cavity 101, it drives the movable plate 400 to adjust its position, thereby improving the fluidity of the water in the cavity 101. Furthermore, a square groove 401 is provided in the middle of the movable plate 400, and a filter element 410 is snapped into the square groove 401; a filter screen 411 is provided in the middle of the filter element 410, and a filter cavity 412 is provided in the middle of the filter element 410. A filter membrane is provided inside the filter cavity 412, allowing water to freely pass through the filter membrane and enter the cavity 101 between the two movable plates 400; a filter ring 111 is provided inside the output pipe 110. When the movable plate 400 is moving, the water flows through the filter mesh 411 and enters the filter cavity 412 through the filter element 410 set in the middle position of the movable plate 400, and finally passes through the filter membrane and enters the middle position of the two movable plates 400. Combined with the fact that the output pipe 110 is located in the middle position of the two movable plates 400, the filtered water can be output from the output pipe 110 for use.

[0033] Preferably, during the above process, after the two movable plates 400 are displaced relative to the cavity 101, a frame 120 is fixedly mounted in the middle of the top surface of the box body 100; two capsules 300 are disposed in the middle of the two movable plates 400; and the two capsules 300 are connected to the interior of the frame 120 via a flexible tube 121. A mounting slot is provided in the middle of the top surface of the box body 100 where the frame 120 is mounted, and an elastic membrane 130 is disposed on the bottom of the mounting slot. When the capsules 300 are compressed, the gas within them enters the mounting slot through the flexible tube 121, thereby causing the elastic membrane 130 to expand and deform. The capsule 300 located between the middle portions of the two movable plates 400 is intermittently compressed. During this process, combined with the connection between the capsules 300 and the interior of the frame 120 via the flexible tube 121, the gas originally within the capsules 300 enters between the middle portions of the frame 120 and the elastic membrane 130, thereby causing the elastic membrane 130 to expand and deform.

[0034] Preferably, in the vertical direction, the elastic membrane 130 is located in the middle of the two bladders 300 and also in the middle of the two movable plates 400; the output pipe 110 is directly below the elastic membrane 130. When the elastic membrane 130 is deformed, it squeezes the space in the cavity 101 between the two movable plates 400, allowing the filtered water in this location to be efficiently discharged from the output pipe 110, ensuring normal water supply to the cleaning machine.

[0035] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
