[0002] Cleaning spray refers to spraying cleaning liquid in the form of water mist through an atomizing nozzle to clean the surface of an object.

[0003] Using a cleaning spray to clean the metal surface can remove foreign objects such as impurities and oil stains on the metal surface. When there is oil stain on the metal surface, high-temperature spray can effectively remove the oil stain on the metal surface to keep the metal clean. However, when the existing spray device is cleaning the metal surface, if the water supply pressure drops, the impact force of the water mist sprayed from the nozzle will decrease, thereby affecting the cleaning effect on the metal surface.

[0004] To this end, the utility model provides a metal surface treatment cleaning spray device. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figures 1 to 3 As shown, a metal surface treatment cleaning spray device described in an embodiment of the utility model comprises a conduit 1; a nozzle 12 is fixedly connected to the bottom end of the conduit 1; a partition plate 13 is fixedly connected to the inside of the nozzle 12; a through hole 14 is opened in the middle of the partition plate 13; a plurality of adjustment components 15 are installed in the middle of the nozzle 12; a first spring 16 is fixedly connected to the side wall of the adjustment component 15 located inside the nozzle 12; a water-blocking ball 17 is fixedly connected to the other end of the first spring 16; when working, the cleaning liquid flows into the inside of the nozzle 12 through the conduit 1, and then sprays out through the plurality of spray holes at the bottom of the nozzle 12. When the water supply pressure is sufficient, the water flow will squeeze the water blocking ball 17 and flow into the cavity between the nozzle 12 and the partition plate 13, so that the cleaning liquid can be sprayed out from all the spray holes at the bottom of the nozzle 12, and then form a spray to rinse the metal surface. When the water supply pressure is low, the water pressure is not enough to push the water blocking ball 17 to squeeze the first spring 16, so that the cleaning liquid is difficult to spray out through the spray holes near the outer circle of the nozzle 12, thereby reducing the impact force of the water sprayed from the spray holes near the inner part of the bottom of the nozzle 12, thereby reducing the impact of the water flow impact force on the metal surface caused by the decrease in the impact force of the water flow.

[0024] like Figures 1 to 5 As shown, a fixed cylinder 2 is fixedly connected to the middle of the conduit 1; a slider 21 is slidably connected to the middle of the fixed cylinder 2; a pair of water channels 22 are opened in the middle of the slider 21; a filter plate 23 is detachably installed in the middle of the water channel 22; when working, the cleaning liquid will flow inside the conduit 1, and when the cleaning liquid flows through the filter plate 23, some impurities in the cleaning liquid will be filtered by the filter plate 23, thereby reducing the occurrence of blockage of the spray hole of the nozzle 12.

[0025] like Figures 1 to 3As shown, the adjustment assembly 15 includes an adjustment bolt 3; the adjustment bolt 3 is threadedly connected to the middle part of the nozzle 12; the end of the adjustment bolt 3 facing the inside of the nozzle 12 is rotatably connected to a slide rod 31; the slide rod 31 is slidably connected to the middle part of the nozzle 12; the water-blocking ball 17 is fixed to the side wall of the slide rod 31; when working, the adjustment bolt 3 can be rotated to drive the slide rod 31 to slide, thereby adjusting the compression degree of the first spring 16, thereby adjusting the pressure threshold of the water-blocking ball 17, and the device can be adjusted to bias the flushing range or bias the flushing force.

[0026] like Figures 1 to 5 As shown, a pair of operating holes 4 are symmetrically arranged on the top of the fixed cylinder 2; an adjusting groove 41 is opened on the side wall of the fixed cylinder 2; during operation, when some impurities are accumulated inside a filter plate 23, the slider 21 can be slid from one end of the fixed cylinder 2 to the other end, so that the filter plate 23 accumulated with impurities is separated from the waterway, and the clean filter plate 23 enters the waterway, and then the filter plate 23 with impurities is taken out through the operating hole 4 for cleaning or replacement.

[0027] like Figures 1 to 5 As shown, a slot 5 is provided on the side wall of the slider 21; a pair of limit posts 51 are slidably connected to the side wall of the fixed cylinder 2; a second spring 52 is fixedly connected to the middle of the limit post 51; the other end of the second spring 52 is fixedly connected to the side wall of the fixed cylinder 2; after the position adjustment of the slider 21 is completed, a limit post 51 will enter the inside of the slot 5 under the elastic force of the second spring 52, thereby limiting the movement of the slider 21, thereby reducing the occurrence of displacement of the slider 21 when water flows through.

[0028] like Figures 1 to 5 As shown, a plug 6 is detachably installed in the middle of the operating hole 4; a pull ring 61 is fixed to the top of the plug 6; through the above structure, the occurrence of impurities entering the filter plate 23 that is not in the water channel and causing pollution can be reduced.

[0029] like Figure 3 As shown, the side wall of the slide rod 31 is fixedly connected with an elastic film sleeve 7; the other end of the elastic film sleeve 7 is fixedly connected to the inner wall of the nozzle 12; through the above structure, the occurrence of cleaning liquid flowing out from between the slide rod 31 and the nozzle 12 can be reduced.

[0030] During operation, the cleaning liquid flows into the interior of the nozzle 12 through the conduit 1, and then is sprayed out through the multiple spray holes at the bottom of the nozzle 12. When the water supply pressure is sufficient, the water flow will squeeze the water blocking ball 17 and flow into the cavity between the nozzle 12 and the partition plate 13, so that the cleaning liquid can be sprayed out from all the spray holes at the bottom of the nozzle 12, and then form a spray to rinse the metal surface. When the water supply pressure is low, the water pressure is not enough to push the water blocking ball 17 to squeeze the first spring 16, so that the cleaning liquid is difficult to spray out through the spray holes near the outer circle of the nozzle 12, and the cleaning liquid will flow inside the conduit 1 and When the liquid flows through the filter plate 23, some impurities in the cleaning liquid will be filtered by the filter plate 23. The adjusting bolt 3 can be rotated to drive the slide bar 31 to slide, thereby adjusting the compression degree of the first spring 16, thereby adjusting the pressure threshold of the water-blocking ball 17. When some impurities are accumulated inside a filter plate 23, the slide bar 21 can be slid from one end of the fixed tube 2 to the other end, so that the filter plate 23 accumulated with impurities is separated from the waterway, and the clean filter plate 23 enters the waterway. After the position adjustment of the slide bar 21 is completed, a limit column 51 will enter the interior of the card slot 5 under the elastic force of the second spring 52.
