Description

Technical Field

[0001] This utility model relates to the field of sanitary ware technology, and in particular to a toilet flushing nozzle. Background Technology

[0002] Existing toilet structures typically employ a jet nozzle installed at the bottom of the toilet bowl to guide water flow into the water seal of the toilet bowl. The siphon effect, created by the pressure of tap water, propels the water flow into the U-shaped bend of the ceramic body within the toilet bowl, achieving waste removal through high-pressure, high-flow-rate water jets. However, in actual use, when feces fall to the bottom of the toilet, they tend to adhere to the bottom of the toilet bowl and the sides of the bottom.

[0003] Although toilets are usually equipped with a main flush head and a brush ring, the main flush head only sprays the U-shaped bend of the ceramic body and does not clean the bottom and side walls of the toilet, so the cleaning effect is limited. As for the brush ring, due to the water seal at the bottom of the toilet, the water from the brush ring washes from top to bottom, and there is basically no cleaning force when it reaches the bottom of the toilet, so it also fails to achieve the purpose of cleaning.

[0004] In view of the above, the designer of this utility model designed this utility model. Utility Model Content

[0005] The purpose of this invention is to provide a toilet flushing nozzle that can improve the flushing effect.

[0006] To achieve the above objectives, the present invention adopts the following solution:

[0007] A toilet flushing nozzle is installed at the bottom of the side wall of a toilet bowl, comprising: a nozzle body having an inlet, a jet channel, and a jet nozzle that are interconnected, the jet nozzle being directly opposite the U-shaped bend of the ceramic body of the toilet bowl, and the nozzle body further comprising a guide portion that allows water to be sprayed out in a wide-angle manner.

[0008] Preferably, the guide portion includes a flushing channel at a certain angle to the horizontal direction, the flushing channel is connected to the jet channel, and the jet nozzle is radially spaced from the flushing channel.

[0009] Furthermore, the flushing channel is located at the bottom and / or left and / or right side of the spray nozzle.

[0010] Furthermore, a water replenishment channel is provided at the top of the spray nozzle, and the water replenishment channel is arranged in parallel with the spray nozzle and the flushing channel at intervals.

[0011] Furthermore, the nozzle body is externally sealed with a water supply connector, which has a first water inlet and a second water inlet. The first water inlet is connected to the water supply channel and the toilet's water supply path, and the second water inlet is connected to the water inlet and the toilet's flushing path.

[0012] Furthermore, the water replenishment connector and the nozzle body are sealed together by a sealing ring; the outer side of the nozzle body is provided with threads, and an upper connecting nut and a lower connecting nut are screwed into the threads near the water replenishment connector. The upper connecting nut and the lower connecting nut are detachably connected, and the upper connecting nut and the lower connecting nut press the water replenishment connector onto the nozzle body.

[0013] Furthermore, a locking nut and a sealing washer are screwed onto the threaded part, with the locking nut positioned between the upper connecting nut and the spray nozzle of the nozzle body.

[0014] Furthermore, the cross-section of the flushing channel is crescent-shaped.

[0015] Preferably, the guide section further includes a rotating core and a shaping cavity arranged sequentially along the water flow direction. The rotating core is fixedly installed upstream of the flushing channel. The sidewall of the rotating core has multiple spaced oblique grooves. The shaping cavity is used to regulate and guide the size of the water flow range. The water in the jet channel enters the oblique grooves and the jet nozzle respectively. The water passing through the oblique grooves forms a spiral water. The spiral water is shaped by the shaping cavity and then sprayed out from the flushing channel.

[0016] Preferably, the flow guide further includes an impeller and a shaping cavity arranged sequentially along the water flow direction. The impeller is fixedly disposed in the jet channel, and the shaping cavity is used to rectify and guide the size of the water flow range and is connected to the jet nozzle. The water in the jet channel forms a spiral water after passing through the impeller. The spiral water is shaped by the shaping cavity and then ejected from the jet nozzle.

[0017] As can be seen from the above technical solution, this utility model, by setting a guide section that allows water to be sprayed out in a wide-angle manner, ensures that the water used for flushing the toilet bowl is treated by the guide section and then sprayed out in a wide-angle manner. That is, the guide section expands the spray range of the water flow. The water flowing out through the spray nozzle will flush the U-shaped bend of the ceramic body of the toilet bowl, and the water flowing out through the guide section will also flush the side walls and bottom of the toilet bowl, thereby improving the flushing effect.

[0046] Furthermore, the accompanying drawings are merely illustrative of this disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted. Some block diagrams shown in the drawings are functional entities and do not necessarily correspond to physically or logically independent entities.

[0047] Reference Figures 1-11 As shown, this utility model discloses a toilet flushing nozzle, which is installed at the bottom of the side wall of the toilet bowl 3. It includes: a nozzle body 1, which has a jet flow channel 11, a jet port 12 and a water inlet 13 that are interconnected. The jet port 12 is directly opposite the U-shaped bend 31 of the ceramic body of the toilet bowl 3. The nozzle body 1 is provided with a guide part 2 that allows water to be sprayed out in a wide-angle manner. The guide part 2 is located near the jet port 12.

[0048] Therefore, by setting up a guide section 2 that allows water to be sprayed out in a wide-angle manner, the water used to flush the toilet bowl 3 is processed by the guide section 2 and then sprayed out in a wide-angle manner. That is, the guide section 2 can expand the spray range of the water flow. The water flow flowing out through the spray nozzle 12 will flush the ceramic U-shaped bend 31 of the toilet bowl 3. In conjunction with the water flow flowing out through the guide section 2, it will also flush the side walls and bottom of the toilet bowl 3. The wide-angle spray of water flow can effectively wash away the stains on the bottom and side walls of the toilet bowl 3, thereby improving the flushing effect.

[0049] Furthermore, to facilitate installation and fixation, a retaining plate 15 is formed on the outer side of the nozzle body 1 near the spray port 12, and a perforation 32 is provided at the bottom of the side wall of the toilet bowl 3. The nozzle body 1 passes through the perforation 32 in a sealed manner, and the retaining plate 15 is secured to the side wall of the toilet bowl 3.

[0050] Preferably, the nozzle body 1 is a long tube shape.

[0051] Please see Figures 1 to 4 The first embodiment of this utility model is shown below. Figures 5 to 7 The second embodiment of this utility model shown is as follows: Figures 8 to 11 The differences between the three embodiments of this utility model shown are as follows:

[0052] In Embodiment 1, the flow guide 2 includes a flushing channel at a certain angle to the horizontal direction. The flushing channel is connected to the jet channel 11, and the jet nozzle 12 is radially spaced from the flushing channel. The flushing channel includes an inclined bottom flushing channel 21, thereby achieving flushing of the sidewalls and bottom of the toilet bowl 3. The jet nozzle 12 is located in the middle of the jet channel 11, and the jet nozzle 12 is radially spaced from the bottom flushing channel 21.

[0053] The flushing channel is located at the bottom and / or left and / or right side of the spray nozzle 12; the cross-section of the flushing channel is crescent-shaped.

[0054] Furthermore, in order to enhance the flushing of the toilet bowl's sidewalls, the flow guide 2 may also include an auxiliary flushing channel 22, which is located on the left and / or right side of the jet channel 11.

[0055] Preferably, the top of the spray nozzle 12 is provided with a water replenishment channel 23, which is arranged side by side with the spray nozzle 12 and the flushing channel at intervals, so as to use the water flow of the water replenishment channel 23 to replenish and flush the toilet bowl 3.

[0056] Furthermore, in order to facilitate the replenishment of water to the water replenishment channel 23, a water replenishment connector 4 is provided on the external seal of the nozzle body 1. The water replenishment connector 4 has a first water inlet 42 and a second water inlet 43. The first water inlet 42 connects the water replenishment channel 23 and the water replenishment path of the toilet (not shown), and the second water inlet 43 connects the water inlet 13 and the flushing path of the toilet (not shown).

[0057] Preferably, for easy water intake, a water inlet connector 7 is formed at the first water inlet 42.

[0058] To improve sealing, the water supply connector 4 and the nozzle body 1 can be sealed together by a sealing ring 5.

[0059] Furthermore, for ease of installation, the outer side of the nozzle body 1 is provided with a thread 14. An upper connecting nut 61 and a lower connecting nut 62 are screwed onto the thread 14 near the water supply connector 4. The upper connecting nut 61 and the lower connecting nut 62 are detachably connected, and the upper connecting nut 61 and the lower connecting nut 62 press the water supply connector 4 onto the nozzle body 1.

[0060] Next, in order to improve the connection between the water supply connector 4 and the upper connecting nut 61 and the lower connecting nut 62, a first hook 41 is formed at the end of the water supply connector 4 near the upper connecting nut 61 and the lower connecting nut 62, and a second hook 63 is formed at the end of the upper connecting nut 61 near the water supply connector 4 and the end of the lower connecting nut 62 near the water supply connector 4, respectively. The second hook 63 is hooked onto the first hook 41.

[0061] The upper connecting nut 61 and the lower connecting nut 62 can be detachably connected by cooperating with the fixing hole 81 and the fixing member 82. In the embodiment, the fixing hole 81 can be a riveting hole and the fixing member 82 can be a rivet; but it is not limited thereto.

[0062] In addition, a locking nut 91 and a sealing washer 92 are screwed onto the thread 14. The locking nut 91 is located between the upper connecting nut 61 and the spray port 12 of the nozzle body 1.

[0063] Therefore, water flows out through the bottom flushing channel 21, the water supply channel 23, the auxiliary flushing channel 22, and the jet nozzle 12 to flush the bottom and sidewalls of the toilet bowl 3. Alternatively, water can flow out through the bottom flushing channel 21, the auxiliary flushing channel 22, and the jet nozzle 12 to flush the bottom and sidewalls of the toilet bowl 3, thereby expanding the flushing range.

[0064] In Embodiment 2, the flow guide 2 includes an impeller 24 and a shaping cavity 25 arranged sequentially along the water flow direction. The shaping cavity 25 is connected to the jet nozzle 12, which is located in the middle of the jet flow channel 11. The impeller 24 is fixedly arranged in the jet flow channel 11. The shaping cavity 25 is used to rectify and guide the size of the water flow range. The water in the jet flow channel 11 forms a spiral water after passing through the impeller 24. The spiral water is shaped by the shaping cavity 25 and then sprayed out from the jet nozzle 12.

[0065] Therefore, the water flow will pass through the inclined blades of the impeller 24 to form a spiral water guide to the shaping cavity 25, and then be ejected through the spray nozzle 12 to form a high-speed hollow water flow; the hollow water flow is beneficial for flushing the bottom and side walls of the toilet bowl 3.

[0066] In Embodiment 3, the flow guide 2 includes a rotating core 26, a shaping cavity 25, and an inclined bottom flushing channel 21 arranged sequentially along the water flow direction. The bottom flushing channel 21 has a crescent-shaped cross-section. The rotating core 26 is fixedly installed upstream of the flushing channel (i.e., the rotating core 26 is installed at the water inlet end of the bottom flushing channel 21). The sidewall of the rotating core 26 has multiple spaced inclined grooves 261. The shaping cavity 25 is connected to the bottom flushing channel 21 and is used to regulate and guide the water flow range. The spray nozzle 12 is located in the middle of the spray channel 11. The rotating core 26 has a connecting hole 262 in the middle, which is connected to the spray nozzle 12. The water in the spray channel 11 enters the inclined grooves 261 and the spray nozzle 12 respectively. The water passing through the inclined grooves 261 forms a spiral water. The spiral water is shaped by the shaping cavity 25 and then sprayed out from the flushing channel.

[0067] Therefore, a portion of the water flow will pass through the inclined groove 261 of the rotating core 26 to form a spiral water guide to the shaping cavity 25 to form a high-speed rotation, and then be ejected through the crescent-shaped bottom flushing channel 21 to form a high-speed semi-hollow water jet; another portion of the water flow will be ejected directly from the jet nozzle 12 at high speed. The crescent-shaped hollow water jet is conducive to flushing the bottom and sides of the toilet bowl 3 and the dirt. The high-speed jet in the middle can easily form a siphon and improve the flushing performance of the toilet.
