Description

Technical Field

[0001] The present application relates to the field of intelligent bathroom technology, and in particular to a bottom flushing nozzle and an intelligent toilet. Background Art

[0002] Toilets are inseparable from people's lives. Everyone must use them every day. With the development of society, people's living standards are improving day by day, and people's requirements for toilets are getting higher and higher.

[0003] Many smart toilets on the market currently use siphon drainage in their flushing systems. Siphon flushing systems generally have two water outlet nozzles, one is a side-flushing nozzle located on the upper part of the ceramic bowl, which flushes the ceramic bowl from top to bottom, and the other is a bottom-flushing nozzle located at the water trap at the bottom of the ceramic bowl, which flushes backward. When siphon drainage is used in the flushing system, a certain flushing force must be provided to better empty the dirt in the toilet.

[0004] However, the applicant discovered in the process of implementing this application that the existing bottom-flushing nozzle design is relatively simple. Currently, there are mainly two types of circular hole-type water outlets and flat hole-type water outlets. The circular hole-type water outlet has a large water flow rate and a relatively concentrated water column. It is more effective when flushing a single large mass of dirt (such as MISO), but leaves more residue when flushing small particles and sawdust-type dirt. The water flow velocity direction of the flat hole-type water outlet is distributed in a trumpet shape, with a large flow rate and a relatively dispersed water column. It is more effective when flushing small particles and sawdust-type dirt, but has poor performance when flushing a single large mass of dirt (such as MISO).

[0005] From the perspective of flushing and sewage discharge, both have their own advantages and disadvantages, but neither is perfect. In order to solve the above problems, it is necessary to provide a new bottom flushing nozzle and intelligent toilet. Utility Model Content

[0055] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0056] In the prior art, such as Figure 1a-Figure 1c As shown in the figure, the shape of the water outlet of the round hole nozzle is a round hole or a nearly round hole, and the cross-sectional area of ​​the water outlet hole is smaller than the cross-sectional area of ​​the nozzle body. Its flushing characteristics are that the water flow velocity direction of the water outlet hole is basically parallel to the axis of the nozzle body, the water flow rate is large, and the water column is relatively concentrated. It has a better effect when flushing a single large mass of dirt (such as MISO). When flushing small particles and wood chips, more residues will remain. Figure 2a-2c As shown in the figure, the shape of the outlet hole of the flat-hole nozzle is relatively large in length and width (such as smiley face, crescent, and elliptical). Generally, the size in the horizontal direction is much larger than the size in the vertical direction. Its flushing characteristics are that the water flow velocity direction of the outlet hole is distributed in a trumpet shape, the flow velocity is large, and the water column is relatively dispersed. It is more effective when flushing small particles and wood chips. When it comes to single large-mass dirt (such as MISO), the performance is poor.

[0057] To this end, the present application provides a bottom flushing nozzle and an intelligent toilet. Figure 3As shown, the smart toilet includes a toilet body 1, a side flushing port 11 is provided on the top side of the toilet body 1, a brush ring water channel 12 is provided on the top side ring of the toilet body 10, the side flushing port 11 is used to install a side flushing nozzle, the side flushing nozzle is connected to the brush ring water channel 12, and is used to clean the inner side wall of the toilet body 1. A bottom flushing port 13 is provided on the bottom side of the toilet body 1, and the bottom flushing port 13 is used to install a bottom flushing nozzle 2, and the bottom flushing nozzle 2 is used to clean the bottom of the toilet body 1.

[0058] For the convenience of description, this application takes the width direction of the toilet body as the first direction x, the height direction of the toilet body as the second direction y, and the length direction of the toilet body as the third direction z, wherein the first direction x, the second direction y and the third direction z are perpendicular to each other.

[0059] In some embodiments, Figure 4 and Figure 5 As shown, the bottom flush nozzle 2 includes a nozzle body 21, and the nozzle body 21 includes a proximal end 211 and a distal end 212 that are relatively arranged. A water inlet channel 200 is arranged in the nozzle body 21, and a water inlet 201 is arranged near the proximal end 211 of the water inlet channel 200, and a water outlet 202 is arranged near the distal end 212 of the water inlet channel 200. The diameter of the water outlet 202 is smaller than the diameter of the water inlet 201, so as to increase the flow rate and improve the flushing intensity.

[0060] In some embodiments, the nozzle body 21 is substantially cylindrical. Figure 6 and Figure 7 As shown, the center of the water inlet 201 coincides with the central axis OA of the nozzle body 21 , and the center of the water outlet 202 is offset away from the central axis OA of the nozzle body 21 toward the bottom of the toilet body 1 , which is beneficial to flushing the bottom of the toilet body 1 .

[0061] It should be noted that the central axis OA of the nozzle body is parallel to the third direction z.

[0062] In some embodiments, Figure 5 As shown, a guide portion 203 is provided in the water inlet channel 200, the guide portion 203 is arranged near the distal end 212, and the guide portion 203 extends from the inner wall of the water inlet channel 200 to the water outlet 202, and the guide portion 203 is used to guide the water in the water inlet channel 200 to the water outlet 202. Further, along the direction extending from the proximal end 211 to the distal end 212, the angle between the guide portion 203 and the central axis OA of the nozzle body 21 is 45°, so as to change the direction of the water flow in the water inlet channel 200, so that the water outlet 202 is aligned with the bottom of the toilet body 1.

[0063] In some embodiments, the bottom punch nozzle 2 includes a cover plate 22, which is connected to the distal end 212 of the nozzle body 21. Along the radial direction of the nozzle body 21, the cross-sectional dimension of the cover plate 22 is larger than the cross-sectional dimension of the nozzle body 21, so that the cover plate 22 is conveniently clamped in the bottom punch opening 13.

[0064] Furthermore, the cover plate 22 is provided with a first water outlet hole 221 and a second water outlet hole 222, and both the first water outlet hole 221 and the second water outlet hole 222 are connected to the water outlet 202. Along the first direction x, the cross-sectional dimension of the second water outlet hole 222 is larger than the cross-sectional dimension of the first water outlet hole 221, so that the first water outlet hole 221 is used to flush a single large mass of dirt (such as MISO), and the second water outlet hole 222 is used to flush small particles and wood chips.

[0065] In some embodiments, the centers of the first water outlet hole 221 and the second water outlet hole 222 are both away from the central axis OA of the nozzle body 21 and offset toward the bottom of the toilet body 1 .

[0066] In some embodiments, along the second direction y (the extension direction from the bottom of the toilet body 1 to the top of the toilet body 1 ), the second water outlet hole 222 is located below the first water outlet hole 221 .

[0067] In some embodiments, the cover plate 22 and the nozzle body 21 are integrally formed.

[0068] In some embodiments, Figure 8 and Fig. 9 As shown, the first water outlet 221 is a special-shaped hole and is arranged in an axisymmetric manner. The first water outlet 221 includes a first portion 221a and a first diffusion portion 221b extending outward from both sides of the first portion 221a along the first direction x. The first portion 221a is roughly rectangular, and the first diffusion portion 221b is roughly semi-elliptical.

[0069] It can be understood that the center of the first portion 221 a is offset downward from the central axis OA of the showerhead body 21 .

[0070] In some embodiments, the area of ​​the two first diffusion portions 221 b is less than 1 / 5 of the area of ​​the first portion 221 a.

[0071] In some embodiments, Fig. 9 As shown, the width of the first part 221a is defined as AW1, the height of the first part 221a is defined as AH1, the width of the first diffusion part 221b is defined as AW1, the height of the first diffusion part 221b is defined as AH2, and the dimensions of the first water outlet 221 satisfy: AW1∶AH1∶AW2∶AH2≈6∶5∶2.5∶2.

[0072] In some embodiments, Figure 8 As shown, the second water outlet 222 is in the shape of an elongated circular arc and is arranged in an axisymmetric manner. The second water outlet 222 bends in the direction close to the first water outlet. The second water outlet 222 has a first elongated portion B, a second elongated portion C, and a third elongated portion D from the inside to the outside. The area of ​​the second water outlet 222 changes to be the largest in the middle, shrinks symmetrically to both sides (the first direction x), and then expands appropriately, which helps to concentrate the dispersed water surface layer and avoid the loss of impact force. The first elongated portion B, the second elongated portion C, and the third elongated portion D have the same size at the widest part of the cross section. Fig.10a As shown, the size characteristics of the cross section of the first elongated portion B are: BH1: BH2: BY: BW≈1: 1.7: 2: 18. The first elongated portion B includes a second upper portion 222b1, a second lower portion 222b2, and a second diffusion portion extending from the second upper portion 222b1 to both sides along the first direction x. The maximum width of the cross section of the first elongated portion B is BW, the height of the second upper portion 222b1 is BH1, the sum of the heights of the second upper portion 222b1 and the second lower portion 222b2 is BH2, and the edge of the second diffusion portion is in a circular arc transition, and the diameter of the circular arc is BY.

[0073] like Fig.10b As shown, the size characteristics of the cross section of the second elongated portion C are: CH1:CH2:CW≈2.3:3.3:6.2. The second elongated portion C includes a second upper portion 222c1, a second lower portion 222c2, and a second diffusion portion extending from the second upper portion 222c1 to both sides along the first direction x, the width of the second lower portion 222c2 is CW, the height of the second upper portion 222c1 is CH1, and the sum of the heights of the second upper portion 222c1 and the second lower portion 222c2 is CH2.

[0074] like Fig.10c As shown, the cross-sectional dimension of the third elongated portion D is: DH: DW≈3.8: 12. The third elongated portion D includes a second upper portion 222d1, a second lower portion 222d2, and a second diffusion portion extending from the second upper portion 222d1 to both sides along the first direction x. The sum of the heights of the second upper portion 222d1 and the second lower portion 222d2 is DH, and the width of the second lower portion 222d2 is DW.

[0075] In some embodiments, the ratio of the cross-sectional area of ​​the first elongated portion B, the cross-sectional area of ​​the second elongated portion C, and the cross-sectional area of ​​the third elongated portion D is BS:CS:DS≈30:38:57. The cross-sectional area can be obtained by image processing.

[0076] It should be noted that the diffusion portions of the first elongated portion B, the second elongated portion C, and the third elongated portion D have the same size and shape.

[0077] It is understandable that the above dimensions can be scaled according to actual needs.

[0078] In some embodiments, the first water outlet hole 221 and the second water outlet hole 222 both extend into the water inlet channel 200. Fig.11 As shown, the ratio of the extending distance of the cross section of the first elongated portion B, the extending distance of the cross section of the second elongated portion C and the extending distance of the cross section of the third elongated portion D is L3:L2:L1≈17:17:3.9.

[0079] In some embodiments, Fig.11 As shown, a guide block 223 is provided between the first water outlet 221 and the second water outlet 222 , and the guide block 223 is used to divert water in the water inlet channel 200 , one way of which enters the first water outlet 221 and the other way of which enters the second water outlet 222 .

[0080] In some embodiments, the included angle between the guide block 223 and the central axis OA of the nozzle body is 45°.

[0081] By setting the guide part 203 and the guide block 223, a first water outlet channel is formed between the guide part 203 and the first water outlet hole 221, and a second water outlet channel is formed between the guide block 223 and the second water outlet hole 222. When flushing, the water in the water inlet channel 200 is divided into two paths, one of which enters the first water outlet channel, where the water column has a good concentration and is sprayed along the axis of the bottom flushing nozzle as a whole. After the water column is sprayed, it directly acts on the dirt with a larger mass in the water and pushes it into the drain bend of the toilet. The other path enters the second water outlet channel, where the water column diffuses in a trumpet shape and is slightly downward in angle as a whole. After the water column is sprayed, it flushes the ceramic walls at the bottom and both sides of the water trap, and flushes the dirt attached to the wall and the dirt in the pipe into the drain bend of the toilet.

[0082] It should be noted that the number and shape of the above-mentioned water outlet holes are not unique and can be adjusted according to the actual shape of the toilet drain elbow to achieve the above-mentioned flushing effect. In addition, the guide block can be designed according to the number of water outlet holes, and the angle between the guide block and the central axis OA of the nozzle body can be adjusted to achieve the best injection and diffusion angle for each water flow.

[0083] In some embodiments, Figure 3 As shown, in order to avoid water leakage, a first sealing member 3 is provided between the cover plate 22 and the bottom punching opening 13 , and a second sealing member 4 is provided between the nozzle body 21 and the bottom punching opening 13 .

[0084] The embodiment of the present application provides a bottom-flushing nozzle and a smart toilet. Compared with the traditional round-hole bottom-flushing nozzle, when the flushing capacity is basically the same, the nozzle of the present application has a better performance in the test of flushing sawdust and small particles. Compared with the traditional flat-hole bottom-flushing nozzle, when the flushing capacity is basically the same, the nozzle of the present application has a better performance in the test of flushing sawdust and small particles.

[0085] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Under the concept of the present application, the technical features in the above embodiments or different embodiments may also be combined, the steps may be implemented in any order, and there are many other changes in different aspects of the present application as described above, which are not provided in detail for the sake of simplicity. Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
