Description

Technical Field

[0001] The utility model relates to the technical field of bathrooms, in particular to a flushing nozzle for a urinal. Background Art

[0002] A urinal nozzle is an accessory installed on a urinal, and is used to flush the wash surface of the urinal. The nozzle is usually installed in the center of the upper part of the urinal, and the water outlet of the nozzle is set at the bottom of the nozzle. For example, a Chinese patent with a publication number of CN221118686U discloses a urinal nozzle, including a nozzle body and a knob. The nozzle body includes a fixing part for connecting to a flushing pipe and a water outlet. The fixing part is located at the rear end of the nozzle body, and the water outlet is located at the bottom of the nozzle body. Water flows into the nozzle body from the fixing part, and the water flows forward to the knob. During this period, the water flows to the water outlet under the action of the gravity of the water flow, resulting in a slow flow rate of the water flowing out of the water outlet, which is not conducive to flushing the inner surface of the urinal. In view of this, the utility model proposes a urinal flushing nozzle to solve the above problems. Utility Model Content

[0003] The utility model overcomes the shortcomings of the above-mentioned technology and provides a urinal flushing nozzle. In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0004] A flushing nozzle for a urinal comprises a nozzle shell, a water inlet pipe opening is arranged at the top of the nozzle shell, a water outlet gap is arranged at the bottom of the nozzle shell, the water outlet gap extends to the left and right sides of the nozzle shell, the rear end of the nozzle shell faces the inner surface of the urinal, and the water outlet gap is closer to the rear end of the nozzle shell than the water inlet pipe opening.

[0005] Preferably, the nozzle shell includes a front half shell and a rear half shell connected to the front half shell, the rear half shell faces the inner surface of the urinal; the front half shell is an arc shell, and the front half shell gradually tilts backward from its center to the periphery; the water inlet pipe port is arranged at the top of the front half shell, and the water outlet gap is arranged at the bottom of the rear half shell.

[0006] Preferably, the water outlet gap gradually tilts forward from the middle to both ends.

[0007] Preferably, the water outlet gap comprises a first water outlet section and second water outlet sections located at both ends of the first water outlet section, and the width of the first water outlet section is greater than that of the second water outlet section.

[0008] Preferably, the front half shell is provided with a mounting hole, and the mounting hole is not connected with the inner cavity of the nozzle shell.

[0009] Preferably, the mounting hole extends to the rear half shell.

[0010] Preferably, the flushing nozzle further comprises a nut for mounting the nozzle housing on the urinal, and the nut is threadedly connected to the outer surface of the water inlet pipe opening.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. Water flows downward from the water inlet into the nozzle housing. During this period, the water flow speed continues to increase under the action of water gravity, so that the water flow velocity from the water outlet gap is relatively large, which is conducive to flushing the inner surface of the urinal. In addition, the rear end of the nozzle housing faces the inner surface of the urinal, and the water outlet gap is closer to the rear end of the nozzle housing than the water inlet, so that the water flowing out of the water outlet gap flushes the inner surface of the urinal backward and downward, with a stronger impact on the wall and a cleaner wash.

[0013] 2. The water inlet is arranged at the top of the front half shell, and the water outlet gap is arranged at the bottom of the rear half shell. The water flows into the nozzle housing from the water inlet. Since the front half shell gradually tilts backward from its center to the periphery, the water flows along the inner surface of the front half shell to the water outlet gap. The front half shell plays a guiding role, so that the water flows gradually backward to the water outlet gap. The flushing force of the water flow backward is increased, which is conducive to flushing the inner surface of the urinal located behind the nozzle housing.

[0014] 3. The water flows backward from the water outlet gap to the inner surface of the urinal. Since the water outlet gap gradually tilts forward from the middle to both ends, the water outlet gap gradually moves away from the inner surface of the urinal from the middle to both ends. The water flows out from both ends of the water outlet gap can form a larger flushing surface, which is beneficial to the inner surface of the urinal around the flushing nozzle.

[0018] The implementation, functional features and advantages of the present invention will be further described in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0019] The following examples further illustrate the features of the present invention and other related features to facilitate understanding by those skilled in the art:

[0020] Reference Figure 1-3 , an embodiment of a urinal flushing nozzle of the utility model is proposed:

[0021] A urinal flushing nozzle comprises a nozzle housing 1, a water inlet pipe opening 11 is arranged at the top of the nozzle housing 1, and a water outlet gap 12 is arranged at the bottom of the nozzle housing 1. The water outlet gap 12 extends to the left and right sides of the nozzle housing 1, the rear end of the nozzle housing 1 faces the inner surface of the urinal, and the water outlet gap 12 is closer to the rear end of the nozzle housing 1 than the water inlet pipe opening 11.

[0022] like Figure 1 As shown, the spray head housing 1 comprises a front half shell 13 and a rear half shell 14 connected to the front half shell 13. The rear half shell 14 faces the inner surface of the urinal; the front half shell 13 is an arc shell, and the front half shell 13 gradually tilts backward from its center to the periphery; the water inlet pipe 11 is arranged at the top of the front half shell 13, and the water outlet gap 12 is arranged at the bottom of the rear half shell 14.

[0023] The process of flushing the urinal of the utility model is as follows: Figure 3 As shown, the arrow indicates the direction of water flow. Water flows downward from the water inlet pipe 11 into the nozzle housing 1. During this period, under the action of the gravity of the water flow, the downward flow velocity of the water flow continues to increase, and then the water flows along the inner surface of the front half shell 13 to the water outlet gap 12. Since the front half shell 13 gradually tilts backward from its center to the periphery, the front half shell 13 plays a guiding role, so that the water flows gradually backward to the water outlet gap 12. The flushing force of the water flow backwards increases, which is conducive to flushing the inner surface of the urinal located behind the nozzle housing 1.

[0024] like Figure 3 As shown, the water outlet gap 12 gradually tilts forward from the middle to both ends, so that the water outlet gap 12 gradually moves away from the inner surface of the urinal from the middle to both ends. Since the water flows backward from the water outlet gap 12 to the inner surface of the urinal, the water flowing out from both ends of the water outlet gap 12 can form a larger flushing surface, which is beneficial to the inner surface of the urinal around the flushing nozzle.

[0025] like Figure 2 As shown, the water outlet gap 12 includes a first water outlet section 121 and second water outlet sections 122 located at both ends of the first water outlet section 121. Since the flushing nozzle is usually installed on the inner surface of the upper part of the urinal, the inner surface of the urinal below the flushing nozzle is usually dirtier than the inner surfaces on both sides of the flushing nozzle, the width of the first water outlet section 121 is set larger than the width of the second water outlet section 122 in the utility model, so that the amount of water flushed downward by the flushing nozzle is greater than the amount of water flushed to both sides by the flushing nozzle, and the water flow is reasonably distributed.

[0026] The front half shell 13 is provided with a mounting hole 15, which is not connected to the inner cavity of the nozzle housing 1, and the mounting hole 15 extends to the rear half shell 14. The mounting hole 15 is used to connect the decorative cover. The decorative cover is provided with a buckle, and the decorative cover is connected to the mounting hole 15 through the buckle, so that the decorative cover is installed on the front half shell 13.

[0027] The flushing nozzle also includes a nut 2 for mounting the nozzle housing 1 on the urinal. The nut 2 is threadedly connected to the outer surface of the water inlet pipe opening 11 .

[0028] The flushing spray head of the utility model only has a spray head housing 1 and a nut 2, with fewer parts, simple structure and low cost.

[0029] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
