Description

Technical Field

[0001] The utility model relates to the technical field of toilet accessories, in particular to a backflow-proof toilet spray head. Background Art

[0002] Currently, toilets on the market are mainly divided into direct-flush toilets and jet siphon toilets. Siphonic toilets are further divided into vortex siphons and jet siphons. Siphonic toilets have a complete pipe in the shape of an inverted "S". The slope of the pool wall is relatively gentle, and the noise problem is improved. It has the characteristics of strong sewage discharge capacity and large cleaning area, so most toilets, especially one-piece toilets, use siphonic type.

[0003] Some jet siphon toilets are equipped with a small water pump inside the toilet. The impact of the water pump drives the jet head to spray water, causing the water in the U-shaped tube to produce a siphon and flush the sewage in the toilet. The nozzle of the jet head is set to be semicircular, and during installation, the semicircular nozzle needs to be placed at the bottom to achieve a good jet flushing effect.

[0004] The spray head of an existing jet-type siphon toilet mainly consists of a nozzle with a threaded outer surface and a fixed nut. The interior of the nozzle does not have a blocking effect. Although the smaller nozzle can block larger dirt in the toilet, it cannot block liquid dirt or other smaller dirt. Over time, these dirt will corrode the water pipe and the spray head, resulting in a reduced cleaning effect of the toilet. Utility Model Content

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0028] Example 1

[0029] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , which is the first embodiment of the utility model, provides a backflow-proof toilet spray head, including a spray head 1, the outer surface of the spray head 1 is threadedly connected to a fixing nut 3, a blocking component 6 is provided inside the spray head 1, the outer surface of the spray head 1 is threadedly connected to a connecting nut 5, the bottom end of the connecting nut 5 is provided with a connecting component 4, the blocking component 6 includes a blocking plate 601 hinged on the inner wall of the spray head 1, a connecting ring 602 is fixedly connected to the inner wall of the spray head 1, and the outer surface of the blocking plate 601 and the outer surface of the connecting ring 602 are both provided with magnets.

[0030] Specifically, the inner wall of the nozzle 1 is provided with a slope, a slot is provided at the top of the nozzle 1, a sealing gasket 2 is fixedly connected to the outer surface of the nozzle 1, the outer surface of the blocking plate 601 is provided with rounded corners, the side of the blocking plate 601 is tightly fitted with the inner wall of the nozzle 1, and a sealing ring 603 is fixedly connected to the side of the connecting ring 602 close to the blocking plate 601.

[0031] Furthermore, the blocking plate 601 is hinged to the inner wall of the nozzle 1, and the hinged position remains sealed. Magnets are provided on the outer surfaces of the blocking plate 601 and the connecting ring 602, which enable the blocking plate 601 and the connecting ring 602 to fit together. During the fitting process, the blocking plate 601 squeezes the sealing ring 603, thereby achieving a sealing effect, and finally achieving the function of blocking the sewage in the toilet and preventing the sewage from flowing back and polluting the water pipe. When flushing is required, the impact force of the water flow can drive the blocking plate 601 to disengage from the connecting ring 602, and the blocking plate 601 rotates to the inclined position with the inner wall of the nozzle 1, thereby opening the nozzle 1 and allowing the water flow to spray out. The inclined surface provided inside the nozzle 1 can reduce the space for the water flow in the water pipe, thereby increasing the impact force of the water spray from the nozzle 1, and a slot is provided on the outer surface of the nozzle 1. When installing the nozzle 1, other tools can be inserted into the slot, thereby positioning the direction of the nozzle 1 and facilitating the installation of the nozzle 1.

[0032] Example 2

[0033] Reference Figure 1 、 Figure 2 and Figure 5 , which is the second embodiment of the present utility model, and this embodiment is based on the previous embodiment. The connecting component 4 includes a connecting pipe 402 fixedly connected to the lower surface of the connecting nut 5, the inner wall of the connecting pipe 402 is fixedly connected to an outer casing 403, the inner wall of the outer casing 403 is movably connected to a plurality of balls 404, and the bottom end of the nozzle 1 is fixedly connected to an inner insert 401.

[0034] Specifically, a sliding groove is provided on the inner wall of the outer casing 403 , and the ball 404 slides in the sliding groove. The depth of the inner wall of the sliding groove of the outer casing 403 gradually increases from top to bottom.

[0035] Furthermore, after the nozzle 1 is installed in the toilet, the connecting nut 5 is installed on the outer surface of the nozzle 1, and the connecting nut 5 is rotated so that the connecting nut 5 moves a distance on the outer surface of the nozzle 1, thereby causing the plug-in tube at the tail end of the nozzle 1 to leak out, and then the water pipe is plugged into the plug-in tube, and then the connecting nut 5 is reversed, and the outer casing 403 is driven to move through the connecting tube 402, so that the outer casing 403 moves toward the water pipe. During the movement, the water pipe is gradually pushed by the ball 404 that is movably connected to the inner wall of the outer casing 403. The outer sleeve 403 is squeezed to facilitate the connection of the water pipe. The inner wall depth of the slide groove on the inner wall of the outer sleeve 403 gradually deepens from top to bottom, so that the exposed part of the ball 404 from top to bottom gradually becomes smaller, so that as the outer sleeve 403 gradually moves toward the water pipe, the squeezing force on the water pipe gradually increases, thereby fixing the water pipe. A certain gap is left between the outer sleeve 403 and the plug-in pipe, and the assembled water pipe is inserted into the plug-in block, and the ball 404 can squeeze the water pipe.

[0036] Working principle: During the installation of the jet toilet spray head, insert other tools into the slot to confirm that the spray port of the spray head 1 is located at the bottom, then insert the spray head 1 and the sealing gasket 2 horizontally from the outside of the toilet into the reserved spray port position, fix the spray head 1 on the toilet through the fixing nut 3, then install the connecting nut 5 to the outer surface of the spray head 1, and continue to rotate one end distance to make the plug-in tube at the tail end of the spray head 1 leak out, then plug the water pipe into the plug-in tube, and then reverse the connecting nut 5, and drive the outer casing 403 to move through the connecting tube 402, so that the outer casing 403 moves to the The water pipe moves, and during the movement, the ball 404 movably connected to the inner wall of the outer casing tube 403 gradually squeezes the water pipe, thereby facilitating the connection of the water pipe. When using the toilet, the blocking plate 601 and the connecting ring 602 cooperate with each other through magnets, and the blocking plate 601 squeezes the sealing ring 603, thereby achieving a sealing effect, so that the dirt in the toilet will not pass through the pipe of the spray head and pollute the water pipe. When the toilet needs to be flushed, the water flow hits the blocking plate 601, driving the blocking plate 601 to rotate and open, so that the water flow is sprayed out from the spray head 1 to flush the toilet.
