[0002] Smart toilets are generally flushed through multiple flushing ports to clean the inner wall of the toilet base of the smart toilet, including an upper flushing port set at the top of the toilet base and a lower flushing port set at the bottom of the toilet base. The upper / lower flushing ports of the smart toilet are generally equipped with upper / lower nozzles. The flushing water is respectively transported to the upper / lower nozzles through the water pipes and sprayed out from the water outlet holes of the upper / lower nozzles to clean the inner wall of the toilet base of the smart toilet.

[0003] At present, although the upper / lower nozzles of smart toilets in the industry have certain conflicts in flushing performance, flushing posture and noise, and meet excellent performance, there are still problems of splashing, backflow and loud noise during the flushing process. Therefore, most manufacturers in the industry can only set relevant performance according to national standards. However, with the continuous update of product strength, consumers have higher and higher requirements for smart toilet products, and products that only meet national standards can no longer be well recognized by consumers.

[0031] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0032] The technical solution provides a nozzle assembly of a smart toilet, comprising an upper nozzle 1 and a lower nozzle 2;

[0033] An upper water outlet hole 101 is provided inside the upper nozzle 1. The upper water outlet hole 101 penetrates the upper nozzle 1, and the aperture of the upper water outlet hole 101 gradually increases along the water outlet direction.

[0034] A lower water outlet hole 201 is provided inside the lower nozzle 2 and passes through the lower nozzle 2; the lower water outlet hole 201 includes a guide section 2011 and a spray section 2012 which are interconnected along the water outlet direction, and the height of the guide section 2011 gradually decreases along the water outlet direction.

[0035] In the prior art, the upper nozzle in the smart toilet mainly increases the flow rate by reducing the water outlet diameter, thereby achieving the purpose of increasing the impact force. However, after the flow rate increases, the water in the brush ring flows too fast, and it is easy to splash when washing the inner wall of the toilet base 3; at the same time, after the flow rate increases, the water flow ejected from the upper nozzle (i.e., the water outlet hole inside the upper nozzle) is columnar, and it is impossible to form a "surface" washing shape on the inner wall of the toilet base 3, resulting in a local area that cannot be cleaned.

[0036] Therefore, in order to solve the technical problems existing in the existing upper nozzle, this solution transforms the method of reducing the upper nozzle, which is widely used in the industry, into a method of gradually increasing the aperture along the water outlet direction, such as Figure 1-2As shown, the water jet velocity is reduced and the water flow is dispersed to form a "paving" effect of the upper water outlet 101, ensuring that the water flow can be dispersed in the washing circle to form a good washing effect.

[0037] Furthermore, in the prior art, the lower spray outlet of the smart toilet (i.e., the water outlet hole inside the lower nozzle) generally changes suddenly from a straight channel to a crescent-shaped spray outlet along the water outlet direction. This sudden change will cause turbulence of high-speed jet water flow, causing fluid streamline chaos and leading to more process losses.

[0038] Therefore, in order to avoid the above phenomenon, the present solution adopts a guide structure (i.e., a guide section 2011 whose height gradually decreases along the water outlet direction) in the lower nozzle 2. Figure 3-4 As shown, the streamlines are concentrated into the injection section 2012 to reduce turbulence, and at the same time, the noise problem of the flushing water flow can be effectively reduced.

[0039] To further explain, the upper water outlet hole 101 is trumpet-shaped, and the inner wall diameter of the upper water outlet hole 101 gradually increases along the water outlet direction.

[0040] In a preferred embodiment of the present technical solution, the upper water outlet 101 is trumpet-shaped, which can more effectively disperse the water flow and achieve a "paving" effect of the water flow.

[0041] To further explain, the taper of the upper water outlet 101 is 2.8 to 3.2 degrees.

[0042] As a better embodiment of the above, this solution also limits the taper of the upper water outlet 101, such as Figure 2 As shown in ∠a, in order to achieve the best brushing effect.

[0043] To further explain, the cross section of the guide section 2011 along the length direction includes an upward line 20111 and a downward line 20112, the upward line 20111 extends obliquely downward along the water outlet direction, and the downward line 20112 extends horizontally.

[0044] In another preferred embodiment of the present technical solution, the cross section of the guide section 2011 along the length direction includes an upward line 20111 inclined downward, so that the production difficulty of the lower nozzle 2 can be reduced while maintaining the fluid streamlines consistent.

[0045] To further explain, the inclination angle of the upward line 20111 is 16 to 20 degrees.

[0046] As a better embodiment of the above, this solution also limits the inclination angle of the up line 20111, such as Figure 4 As shown in ∠b in the figure, in order to achieve the best guiding effect.

[0047] Preferably, the inclination angle of the upward line 20111 is 18 degrees.

[0048] To further explain, the cross-sectional shape of the injection section 2012 is a portion of a circular ring.

[0049] In the prior art, the crescent-shaped jet orifice generally refers to a water outlet whose distance from the jet orifice gradually decreases from the middle to the two ends. The kinetic energy of the water column ejected by the above jet orifice is mainly concentrated in the middle, while the impact force in the two end areas is relatively weak, which is not conducive to achieving uniform impact force. In this solution, the cross-sectional shape of the jet section 2012 is preferably a part of a circular ring in which the distance from the jet orifice is equal from the middle to the two ends, so that the kinetic energy of the jet water flow can be dispersed to each outlet of the jet section 2012, forming a water column similar to a "semicircle" well, with uniform impact force and large water output, which is conducive to satisfying the jet force and siphon force during the siphon of the smart toilet.

[0050] To further explain, the cross-sectional shape of the injection section 2012 is a semicircular ring.

[0051] To further explain, a positioning hole 202 is provided on the water outlet surface of the lower nozzle 2, and the positioning hole 202 is a blind hole.

[0052] In the industry, most practices for axial positioning of the nozzle are to directly use the crescent-shaped nozzle as the positioning socket. During manual installation, the nozzle needs to be constantly adjusted, which may cause the nozzle to be deformed or burred. The above defects are likely to cause turbulence in the water flow when the flushing water flows through. Therefore, in a specific embodiment of the present technical solution, a positioning hole 202 can be opened on the water outlet surface of the lower nozzle 2, which can achieve axial positioning when installing the lower nozzle 2, avoiding deformation or burrs of the water outlet of the lower nozzle 2.

[0053] To further illustrate, the positioning hole 202 is located above the injection section 2012, and the positioning hole 202 is in the shape of a regular hexagon.

[0054] A smart toilet, using the nozzle assembly of the smart toilet, also includes a toilet base 3;

[0055] The upper nozzle 1 is installed at the top of the inner cavity of the toilet base 3 , and the lower nozzle 2 is installed at the bottom of the inner cavity of the toilet base 3 .

[0056] This technical solution also proposes a smart toilet using the above-mentioned nozzle assembly, such as Figure 5-6 As shown, it avoids splashing during the flushing process while ensuring the washing effect, and further reduces the problem of flushing noise, so as to overcome the shortcomings of the prior art.
