Toilet nozzle and toilet

Abstract

The present invention discloses a toilet nozzle and a toilet. The toilet nozzle includes a nozzle body, a water inlet provided at one end of the nozzle body, and a first water outlet hole and a second water outlet hole provided at the other end of the nozzle body, each of which is capable of discharging water toward a side facing the other end face of the nozzle body and is connected to the water inlet. The first water outlet hole and the second water outlet hole are distributed left and right, and the spacing between the first water outlet hole and the second water outlet hole gradually increases from one end of the nozzle body to the other end. When the nozzle of the present invention discharges water, two streams of water enter from the left and right sides of the toilet sewage outlet, forming a downstream state with the toilet sewage pipe, thereby preventing the water from directly passing through the sewage outlet and colliding with the inner wall of the sewage pipe, thereby preventing the water from generating a loud toilet flushing noise.

Description

Technical Field

[0001] The present invention relates to the field of sanitary ware, in particular to a toilet spray head and a toilet. Background Art

[0002] A typical toilet is mainly composed of a toilet seat and a water tank, with the water tank located on the top and rear side of the toilet seat. To save space and enhance aesthetics, some toilets do not include a water tank, but are directly connected to tap water. Specifically, a nozzle is provided at the injection hole on one side of the water trap of the toilet seat, and the nozzle is used to connect to the tap water pipe. When the toilet is flushed, tap water enters from the water inlet at one end of the nozzle and is ejected from the water outlet at the other end, flushing the waste in the water trap of the toilet seat toward the sewage pipe. Since the water outlet at the other end of the nozzle is generally centered, or roughly facing the middle of the sewage outlet at the bottom of the toilet bowl, the water ejected forward by the nozzle passes through the sewage outlet and directly hits the wall of the sewage pipe located behind the sewage outlet, thereby generating a large flushing noise. Summary of the Invention

[0003] The present invention aims to solve the technical problems existing in the prior art and provides a toilet nozzle and a toilet capable of reducing flushing noise.

[0004] The technical solution adopted by the present invention to solve its technical problems is: a toilet nozzle, including a nozzle body, a water inlet is provided at one end of the nozzle body, and a first water outlet hole and a second water outlet hole are provided at the other end of the nozzle body, which can discharge water to the side facing the other end face of the nozzle body and are connected to the water inlet. The first water outlet hole and the second water outlet hole are distributed on the left and right, and the distance between the first water outlet hole and the second water outlet hole gradually increases from one end of the nozzle body to the other end.

[0005] Furthermore, the first water outlet hole and the second water outlet hole are both arc-shaped holes whose centers are close to or located at the center of the end surface of the other end of the nozzle body.

[0006] Furthermore, the distance between the first water outlet hole and the second water outlet hole gradually decreases from top to bottom.

[0007] Furthermore, two channels are provided in the nozzle body, one end of the two channels is connected to the water inlet respectively, and the other end of the two channels is connected to the first water outlet and the second water outlet respectively.

[0008] Furthermore, the two channels respectively include a diverter section and a pressurizing section, which are distributed from one end to the other end of the nozzle body, and the inner diameter of the diverter section is larger than the inner diameter of the pressurizing section.

[0009] Furthermore, the two channels are distributed on the left and right and are separated by a retaining wall provided inside the nozzle body.

[0010] Furthermore, the nozzle body is provided with external threads.

[0011] Furthermore, an outer flange is provided at the other end of the nozzle body.

[0012] Furthermore, at least one annular barb is provided on the outer side surface of one end of the nozzle body.

[0013] The present invention further provides a toilet, comprising a toilet seat, wherein the bottom of the toilet bowl of the toilet seat is provided with a spray hole and a sewage outlet, the sewage outlet is opposite to the spray hole and is connected to a sewage pipe; and further comprising a toilet nozzle as described in the present invention above, the nozzle body being inserted into the spray hole, and the other end of the nozzle body facing the interior of the toilet bowl of the toilet seat.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The arrangement of the first and second water outlet holes enables the nozzle of the present invention to discharge water, with two streams of water entering from the left and right sides of the toilet sewage outlet, forming a downstream state with the sewage pipe of the toilet, thereby preventing the water flow from directly passing through the sewage outlet and colliding with the inner wall of the sewage pipe, thereby preventing the toilet from flushing loudly.

[0016] 2. The first water outlet hole and the second water outlet hole are both arc-shaped holes whose centers are close to or located at the center of the end surface of the other end of the nozzle body, so that the shapes of the two water streams sprayed by the nozzle roughly match the walls on the left and right sides of the toilet sewage outlet, thereby further reducing the flushing noise of the toilet.

[0017] 3. The distance between the first water outlet hole and the second water outlet hole gradually decreases from top to bottom, so that the two water flows sprayed from the nozzle are more concentrated at the bottom of the water seal of the toilet bowl, which can push the dirt at the bottom of the water seal to the sewage outlet, achieving a thorough flushing effect.

[0018] 4. The two channels respectively include the diversion section and the pressurizing section, so that the nozzle of the present invention can use the pressurizing section to increase the flushing force of water, thereby improving the flushing effect.

[0030] For examples, see Figures 1-10 As shown, a toilet nozzle of the present invention includes a nozzle body 1, a water inlet 11 is provided at one end of the nozzle body 1, and a first water outlet hole 12 and a second water outlet hole 13 are provided on the cross section of the other end of the nozzle body 1, which can discharge water to the side facing the other end face of the nozzle body 1 and are connected to the water inlet 11. The first water outlet hole 12 and the second water outlet hole 13 are distributed left and right, and the distance L between the first water outlet hole 12 and the second water outlet hole 13 gradually increases from one end of the nozzle body 1 to the other end.

[0031] In this embodiment, the first water outlet hole 12 and the second water outlet hole 13 are arc-shaped holes whose centers are close to or located at the center of the end surface of the other end of the nozzle body 1, and the distance L between the first water outlet hole 12 and the second water outlet hole 13 gradually decreases from top to bottom.

[0032] In this embodiment, the nozzle body 1 is provided with two channels 17, which are arranged on the left and right sides and separated by a retaining wall 18 provided within the nozzle body 1. One end of each channel 17 is connected to the water inlet 11, and the other end of each channel 17 is connected to the first water outlet 12 and the second water outlet 13. Each channel 17 includes a diverter section 171 and a pressurizing section 172, which extend from one end of the nozzle body 1 to the other. The inner diameter of the diverter section 171 is larger than the inner diameter of the pressurizing section 172, and the length of the diverter section 171 is slightly longer than the length of the pressurizing section 172.

[0033] In this embodiment, the nozzle body 1 is provided with external threads 14 for threaded connection with a mounting nut. The other end of the nozzle body 1 is provided with an outer flange 15. A plurality of annular barbs 16 are provided on the outer side of one end of the nozzle body 1. When the nozzle body 1 is connected to a water supply pipe, the barbs 16 can engage the inner wall of the water supply pipe, preventing the nozzle body 1 from retreating.

[0034] The toilet nozzle of the present invention can be used in toilets, especially toilets without water tanks. When installing, first place the nozzle body 1 in the toilet bowl, and make one end of the nozzle body 1 pass through the spray hole 21 at the bottom of the toilet bowl, and then lock it with the installation nut (not shown in the figure). Figure 7 、 Figure 8 As shown, the outer flange 15 at the other end of the nozzle body 1 now abuts the inner side of the toilet bowl bottom, not only providing a certain sealing effect (sealing the gap between the nozzle body 1 and the spray hole 21) but also preventing the nozzle body 1 from moving out of the spray hole 21. For further sealing, a sealing ring can be placed over the nozzle body 1, or glue can be applied between the nozzle body 1 and the spray hole. Afterwards, one end of the nozzle body 1 is then securely connected to the tap water supply pipe.

[0035] When the toilet is flushed, water enters from the water inlet 11 of the nozzle body 1 and is split into two streams by the diversion section 171 of the two channels 17. The two streams are pressurized by the booster sections 172 of the two channels 17 and ejected from the first water outlet 12 and the second water outlet 13 respectively. Since the distance L between the first water outlet 12 and the second water outlet 13 gradually increases from one end to the other end of the nozzle body 1, the two streams of water gradually change their outlet angles as they flow through the first water outlet 12 and the second water outlet 13, causing the two streams to separate into an "eight" shape and enter from the left and right sides of the toilet sewage outlet 22 respectively, forming a downstream state with the sewage pipe 23 of the toilet, as shown in FIG. Figure 9 、 Figure 10 As shown, the water flow will not directly pass through the sewage outlet 22 and collide with the inner wall of the sewage pipe 23, thereby greatly reducing the flushing noise of the toilet.

[0036] Because the first and second water outlet holes 12, 13 are both arc-shaped holes with their centers near or at the center of the end surface of the other end of the nozzle body 1, the shapes of the two water streams ejected from the nozzle roughly match the arc-shaped wall surfaces on the left and right sides of the toilet sewage outlet 22, allowing both water streams to flow effectively along the left and right sides of the sewage outlet 22, thereby further reducing the flushing noise of the toilet. Because the distance L between the first and second water outlet holes 12, 13 gradually decreases from top to bottom, the two water streams ejected from the nozzle are more concentrated at the bottom of the water seal of the toilet bowl, pushing dirt at the bottom of the water seal toward the sewage outlet 22, achieving a thorough flushing effect.

[0037] See Figure 7-10 As shown, a toilet of the present invention comprises a toilet seat 1, a spray hole 21 and a sewage outlet 22 are provided at the bottom of the toilet bowl of the toilet seat 1, the sewage outlet 22 is opposite to the spray hole 21, and is connected to a sewage pipe 23; and also comprises a toilet nozzle as described in the present invention above, the nozzle body 1 is inserted into the spray hole 21, and the other end of the nozzle body 1 faces the inside of the toilet bowl of the toilet seat 1.

[0038] When installing the nozzle of a toilet of the present invention, first place the nozzle body 1 into the toilet bowl, and make one end of the nozzle body 1 pass through the spray hole 21 of the toilet seat 1, and then lock it with a mounting nut (not shown in the figure). Figure 7 、 Figure 8 For sealing, a sealing ring can be put on the nozzle body 1, or glue can be applied between the nozzle body 1 and the injection port to seal. After that, one end of the nozzle body 1 is connected and fixed to the water supply pipe of the tap water.

[0039] In a toilet according to the present invention, when flushing is started, water enters from the water inlet 11 of the nozzle body 1 and is split into two streams by the diversion section 171 of the two channels 17. The two streams are pressurized by the booster sections 172 of the two channels 17 and ejected from the first water outlet 12 and the second water outlet 13, respectively. Since the distance L between the first water outlet 12 and the second water outlet 13 gradually increases from one end to the other end of the nozzle body 1, the two streams of water gradually change their outlet angles as they flow through the first water outlet 12 and the second water outlet 13, causing the two streams to separate into a figure-eight shape and enter from the left and right sides of the toilet sewage outlet 22, respectively, forming a downstream state with the toilet sewage pipe 23, as shown in FIG. Figure 9 、 Figure 10 As shown, the water flow will not directly pass through the sewage outlet 22 and collide with the inner wall of the sewage pipe 23, thereby greatly reducing the flushing noise of the toilet.
