[0001] The utility model relates to the technical field of sanitary ware, and in particular to a foam agent scattering nozzle, an intelligent cover plate and an intelligent toilet. Background Art
[0002] When using the toilet, when excrement falls into the toilet bowl, it is easy for the water seal in the toilet bowl to splash and emit bad odors. Some smart toilets are equipped with a foam shield function, that is, a device that mixes tap water and foam liquid is set in the smart toilet. The device sprays a foam mixture on the surface of the water seal in the toilet bowl to form a foam shield, isolating the air and the water in the toilet bowl, achieving splash and odor prevention effects, and improving the toilet experience.
[0003] However, the existing smart toilet with foam shield function generally has a circular tubular structure for outputting foam liquid, and can only spray the mixed foam mixture onto the water seal surface in the toilet bowl or onto the toilet bowl wall in a certain direction, and the output foam agent can only cover a part of the toilet bowl wall. For the uncovered part of the toilet bowl wall, feces are prone to stick to the wall, and since the excrement sticking to the wall does not fall below the foam layer but is exposed to the air, it still causes odor.
[0004] At present, some smart toilets increase the coverage of the foam liquid and improve the deodorizing effect by adding a motor to drive the foam liquid spray rod to rotate. However, since this smart toilet has an additional circuit drive, the structure is more complicated and the cost is higher. Utility Model Content

[0024] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.
[0025] like Figures 1 to 6 As shown, the utility model discloses an embodiment of a foam agent scattering nozzle, including a shell 1, wherein the shell 1 is provided with a liquid inlet 11, an injection port 12, and a diffusion chamber 13 connecting the liquid inlet 11 and the injection port 12, wherein a central column 14 is provided in the diffusion chamber 13, and the central column 14 is provided with an impact surface 141 arranged opposite to the liquid inlet 11, and the injection port 12 is opposite to an end of the central column 14 away from the liquid inlet 11, and is arranged around the circumference of the central column 14, or is arranged in a circumferential array along the central column 14.
[0026] In this embodiment, a central column 14 is arranged in the diffusion chamber 13 of the nozzle, and an impact surface 141 is arranged on the central column 14 opposite to the liquid inlet 11. After the foam agent enters the diffusion chamber 13 of the nozzle through the liquid inlet 11, it will collide with the impact surface 141, diffuse to the periphery of the central column 14, and spray out to the periphery of the nozzle through the spray ports 12 arranged around the central column 14 or along the circumferential array of the central column 14; the nozzle has a simple structure, and the diffusion of the foam agent of the smart toilet is achieved through the mechanical structure design of the nozzle, which solves the problem that the existing smart toilet foam agent nozzle can only spray the foam agent onto the water seal surface of the toilet bowl. The nozzle structure can realize the function of foam agent diffusion and spraying without the aid of circuit drive, with a small number of parts and low cost.
[0027] The housing 1 of this embodiment specifically includes a nozzle body 1a and a nozzle top cover 1b. The nozzle body 1a is provided with a fixing ring 15 for fixing with the smart cover of the smart toilet. The nozzle top cover 1b is provided with a buckle 16 for snapping and connecting with the nozzle body 1a. The nozzle top cover 1b and the nozzle body 1a are sealed by an O-ring 2 or a sealing flat gasket, which is convenient and quick to install. Among them, the injection port 12, the central column 14, and the baffle plate below are all arranged on the nozzle body 1a, and the liquid inlet 11 is arranged on the nozzle top cover 1b. The nozzle body 1a and the nozzle top cover 1b cooperate to form the diffusion chamber 13. The liquid inlet 11 can be connected to a conventional hose.
[0028] In order to improve the dispersion effect and flow speed of the foaming agent in the diffusion chamber 13, a baffle is further provided in the diffusion chamber 13 in this embodiment, and a flow channel is formed between the baffle and the cavity wall of the diffusion chamber 13 and at least one of the central pillars 14. The baffles are arranged in an array along the circumference of the central pillar 14 to make the foaming agent dispersed evenly in the diffusion chamber 13.
[0029] The diffusion chamber 13 of this embodiment specifically includes a first diffusion chamber 131 and a second diffusion chamber 132. The liquid inlet 11, the first diffusion chamber 131, the second diffusion chamber 132, and the injection port 12 are sequentially connected, the impact surface 141 of the central column 14 is located in the first diffusion chamber 131, and the cross-sectional area of the second diffusion chamber 132 is smaller than the cross-sectional area of the first diffusion chamber 131. When the foaming agent enters the second diffusion chamber 132 from the first diffusion chamber 131, the cross-sectional area decreases, which will help increase the flow rate of the foaming agent.
[0030] The central column 14 of this embodiment is coaxially arranged with the liquid inlet 11, and the projection area of the impact surface 141 along the axial direction of the central column 14 is larger than the projection area of the liquid inlet 11 along the axial direction of the central column 14, so that all the foaming agents flowing into the liquid inlet 11 can collide with the impact surface 141 as much as possible.
[0031] See also Figure 2 The impact surface 141 bulges toward the direction close to the liquid inlet 11 and the axis of the central column 14. The impact surface 141 can be a convex conical surface or a spherical arc surface. When the foaming agent impacts the top of the impact surface 141, it diffuses to the surroundings to enhance the mixing effect.
[0032] Specifically, see Figure 2 and Figure 3, a first baffle 171 is provided in the first diffusion chamber 131, and the first baffle 171 and the cavity wall of the first diffusion chamber 131 form a first flow channel 131c. The maximum width of the first flow channel 131c is preferably not greater than the diameter of the liquid inlet 11, so that the foaming agent in the first diffusion chamber 131 can be divided into multiple streams and pass through the first flow channel 131c at a faster speed. In order to allow the foaming agent colliding with the impact surface 141 to be evenly dispersed to each first flow channel 131c, in this embodiment, it is preferred that a preset distance is set between the first baffle 171 and the central column 14, and the first baffle 171 is provided with a first inclined surface 171d, and the distance between the first inclined surface 171d and the axis of the central column 14 gradually increases toward the end close to the liquid inlet 11, so that the foaming agent after the collision has enough space to rebound and disperse. In this embodiment, the radius of the first diffusion chamber 131 is R, the radius of the second diffusion chamber 132 is r, and the preset distance between the first baffle 171 and the central column 14 is r.
[0033] In addition, a second baffle 172 is disposed in the second diffusion chamber 132 , and the second baffle 172 and at least one of the central column 14 and the chamber wall of the second diffusion chamber 132 form a second flow channel 132 c.
[0034] Combination Figure 4 , wherein the second baffle 172 of this embodiment is arranged corresponding to the first baffle 171, the second baffle 172 is connected to the center column 14 and the cavity wall of the second diffusion cavity 132, and the first baffle 171 and the corresponding second baffle 172 are both extended along the same radial direction of the center column 14, so that the first flow channel 131c corresponds to the second flow channel 132c one by one, and the foaming agent in the first flow channel 131c flows smoothly to the corresponding second flow channel 132c. In this case, the cross-sectional area of the second flow channel 132c is smaller than the cross-sectional area of the first flow channel 131c, and when the foaming agent flows from the narrow first flow channel 131c to the corresponding narrower second flow channel 132c, the flow rate will increase, helping the foaming agent to be ejected at a high speed at the injection port 12.
[0035] The second diffusion cavity 132 is provided with a second inclined surface 132d (see Figure 3 ), the distance between the second inclined surface 132d and the axis of the central column 14 gradually increases toward the end away from the liquid inlet 11, the second inclined surface 132d is arranged at the bottom of the inlet side of the injection port 12, and the outlet side of the injection port 12 is arranged around the bottom edge opening of the outer periphery of the nozzle body 1a, and is evenly distributed around the circular bottom of the nozzle body 1a, and is preferably arranged corresponding to the second flow channel 132c to generate jets diffusing in multiple directions.
[0036] The specific number of the injection ports 12 can be set as required, as long as the diffuse injection effect can be achieved.
[0037] Combination Figure 5 and Figure 6 The injection port 12 is provided with two side walls 121 parallel to the axis of the central column 14, and the distance between the two side walls 121 gradually increases in the direction away from the axis of the central column 14, so as to facilitate the emission of fan-shaped liquid flow and increase the diffusivity of the output liquid flow.
[0038] The foam agent scattering nozzle of this embodiment is applied to the smart cover of the smart toilet. When the foam shield function of the smart cover is working, the liquid flows into the diffusion chamber 13 of the nozzle from the liquid inlet 11. After the liquid flows in, it collides with the impact surface 141 at the end of the central column 14. The impact surface 141 bulges toward the direction close to the liquid inlet 11 and the axis of the central column 14. When the foam agent hits the top of the impact surface 141, it diffuses to the surroundings to enhance the mixing effect. The foam agent is divided into multiple streams and enters the relatively narrow first flow channel 131c. It passes through the first flow channel 131c at a faster speed and then enters the narrower second flow channel 132c. The flow rate increases again and is finally ejected from the injection port 12 as a high-speed liquid flow, forming a liquid flow that diffuses to the surroundings and falls on the water seal surface of the smart toilet and the toilet bowl wall around the water seal, thereby improving the deodorizing effect.

Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
