Description

Technical Field

[0001] This utility model relates to the field of bathroom products technology, and in particular to a spray nozzle, a foam shield system and a smart toilet. Background Technology

[0002] Most toilet foam shield nozzles on the market use a filter screen for foaming. After prolonged use, scale or solid impurities can easily accumulate on the filter screen, reducing the water flow rate and severely affecting the foaming effect and liquid output. Utility Model Content

[0003] The present invention aims to at least partially solve one of the aforementioned technical problems in the related art. To this end, the present invention proposes a nozzle.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] This utility model also proposes a foam shield system with the above-mentioned nozzle.

[0006] This utility model also proposes an intelligent toilet with the above-mentioned foam shield system.

[0007] The nozzle according to a first aspect embodiment of the present invention includes:

[0008] The shell has an internal liquid inlet chamber and a gas-liquid mixing chamber. The liquid inlet chamber has a first liquid inlet, and the gas-liquid mixing chamber has a liquid outlet. A partition is provided between the liquid inlet chamber and the gas-liquid mixing chamber. The partition is provided with a plurality of jet holes. The jet holes are inclined and connect the liquid inlet chamber and the gas-liquid mixing chamber. The side wall of the gas-liquid mixing chamber is provided with a suction hole.

[0009] The extended axes of at least two of the jet holes intersect within the gas-liquid mixing chamber, and the intersection point is located downstream of the suction hole; or, the extended axis of at least one of the jet holes intersects with the sidewall of the gas-liquid mixing chamber, and the intersection point is located downstream of the suction hole.

[0010] The nozzle according to the embodiment of this utility model has at least the following beneficial effects:

[0011] The mixture of water and foaming liquid enters the jet orifice from the inlet chamber. After being accelerated through the jet orifice, it enters the gas-liquid mixing chamber. A negative pressure is generated within the gas-liquid mixing chamber, causing air to be drawn in through the suction orifice. The mixed liquid jets collide with each other or with the inner wall of the gas-liquid mixing chamber, creating turbulence. This turbulence mixes with the air to achieve foaming, and finally, the foaming liquid flows out through the outlet. This invention utilizes the Venturi effect to generate negative pressure to draw in air, and the foaming liquid is formed through self-collision mixing of the jets. It achieves excellent gas-liquid mixing, high foaming liquid utilization efficiency, and good foaming effect. Because there are no obstructions in front of the jet orifice, the water-passing area of ​​the gas-liquid mixing chamber is large, resulting in a large output volume. Even a relatively small inflow pressure is sufficient to allow the foaming water to wash and cover the entire toilet bowl wash surface.

[0012] According to some embodiments of this utility model, the total water passage area of ​​all jet holes is A, and the water passage area of ​​the liquid outlet is B, with 0.3B≤A≤0.7B.

[0013] According to some embodiments of this utility model, the included angle formed by the intersection of the extended axes of the two jet holes is β, and let 6°≤β≤30°.

[0014] According to some embodiments of the present invention, a second liquid inlet is provided on the side wall of the liquid inlet chamber.

[0015] According to some embodiments of the present invention, the jet holes are arranged in a ring array with the central axis of the gas-liquid mixing chamber as the center.

[0016] According to some embodiments of this utility model, the number of air intake holes is the same as the number of jet holes, and the water jets of the air intake holes and the jet holes correspond one-to-one.

[0017] According to some embodiments of the present invention, the gas-liquid mixing chamber is elongated, the liquid outlet is located at one end of the length direction of the gas-liquid mixing chamber, and the jet hole is located at the other end of the length direction of the gas-liquid mixing chamber.

[0028] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0029] Reference Figure 1-4 A nozzle, comprising:

[0030] The housing 100 has an inlet chamber 300 and a gas-liquid mixing chamber 200 inside. The inlet chamber 300 has a first inlet 310, and the gas-liquid mixing chamber 200 has an outlet 210. A partition 400 is provided between the inlet chamber 300 and the gas-liquid mixing chamber 200. The partition 400 is provided with a plurality of jet holes 410. The jet holes 410 are inclined and connect the inlet chamber 300 and the gas-liquid mixing chamber 200. The side wall of the gas-liquid mixing chamber 200 is provided with a suction hole 220.

[0031] like Figure 1-2 As shown, the extended axes of at least two jet orifices 410 intersect within the gas-liquid mixing chamber 200, and the intersection point is located downstream of the suction orifice 220, or, as... Figure 3 As shown, the extended axis of at least one jet hole 410 intersects the side wall of the gas-liquid mixing chamber 200, and the intersection point is located downstream of the suction hole 220, ensuring that the jet flows through the suction hole 220 at a stable high speed, generating a sufficiently strong negative pressure, and ensuring that the suction hole 220 efficiently and stably draws in air.

[0032] Working principle: The mixture of water and foam liquid enters the jet hole 410 from the liquid inlet 300. After being accelerated through the jet hole 410, it enters the gas-liquid mixing chamber 200. A negative pressure is generated in the gas-liquid mixing chamber 200, which causes the air intake hole 220 to draw in air. The mixed liquid jets collide with each other or with the inner wall of the gas-liquid mixing chamber 200 to form turbulence. The turbulence mixes with the air to achieve foaming. Finally, the foam liquid flows out from the liquid outlet 210.

[0033] In some embodiments of this utility model, the total water-passing area of ​​all jet holes 410 is A, and the water-passing area of ​​the liquid outlet 210 is B, with 0.3B≤A≤0.7B. The total water-passing area of ​​the jet holes 410 is controlled within a certain range to achieve a balance between jet velocity, negative pressure intensity, and intracavity pressure: the jet velocity is sufficient to generate negative pressure and draw in an appropriate amount of air; the intracavity pressure is moderate to ensure that the turbulence generated by the jet collision can fully break up the air and form fine foam; and the liquid outlet 210 has a larger area to allow the foam to be discharged smoothly, avoiding foam accumulation and compression due to an excessively small outlet, which would damage the foam structure.

[0034] In some embodiments of this invention, the included angle formed by the intersection of the extended axes of the two jet holes 410 is β, where 6°≤β≤30°. The included angle β directly determines the collision intensity. β being between 6° and 30° ensures that the intersection angle formed by the jets is large enough to create strong turbulence. However, β cannot be too large, because the area near the outlet of the jet hole 410 is a critical region for generating negative pressure. If β is too large, the rebound liquid flow generated by the collision will interfere with the air pressure in this area, causing fluctuations in the negative pressure intensity and affecting the stability of the air intake through the suction hole 220.

[0035] In some embodiments of this invention, a second inlet 320 is provided on the side wall of the liquid inlet chamber 300. The liquid inlet chamber 300 of this invention can be directly filled with a mixture of water and foam liquid, or clean water can be filled with the first inlet 310 and foam liquid can be filled with the second inlet 320. After the clean water and foam liquid are mixed in the liquid inlet chamber 300, they are accelerated through the jet hole 410.

[0036] In some embodiments of this invention, the jet holes 410 are arranged in a ring array around the central axis of the gas-liquid mixing chamber 200. When multiple jet holes 410 are evenly arranged around the central axis, each jet is injected into the gas-liquid mixing chamber 200 at high speed from different directions. The impact forces generated are balanced with each other, avoiding excessively high or low local pressure (such as pressure concentration on one side leading to turbulent liquid flow). This symmetrical pressure field ensures that the air drawn in by the suction hole 220 diffuses evenly in the chamber, rather than gathering on one side, making the bubbles more evenly distributed in the mixture.

[0037] In some embodiments of this invention, the number of air intake holes 220 is the same as the number of jet holes 410, and the water jets from the air intake holes 220 and jet holes 410 correspond one-to-one. The high-speed water jets ejected from the jet holes 410 are the source of negative pressure, and the area with the strongest negative pressure is concentrated around the water jet. The one-to-one correspondence between the air intake holes 220 and jet holes 410 allows more air to be directly drawn in by the negative pressure of the jet, rather than relying on the pressure difference within the cavity for indirect diffusion, resulting in higher air intake efficiency.

[0038] In some embodiments of this invention, the gas-liquid mixing chamber 200 is elongated, with the liquid outlet 210 located at one end along the length of the gas-liquid mixing chamber 200, and the jet orifice 410 located at the other end along the length of the gas-liquid mixing chamber 200. The elongated design of the gas-liquid mixing chamber 200 extends the gas-liquid mixing path, providing ample space and time for negative pressure suction, turbulent mixing, and foam formation.

[0039] In some embodiments of this invention, the number of jet holes 410 is three or more, and the extended axes of all jet holes 410 intersect at a single point within the gas-liquid mixing chamber 200. Multiple jets simultaneously rush toward the same intersection point from different directions, and the kinetic energy of the jets is concentrated and released at the intersection point. The impact force of each jet is superimposed, forming strong turbulence, which can more efficiently tear apart the inhaled air mass and enhance foaming efficiency.

[0040] A foam shield system, including the aforementioned nozzle.

[0041] A smart toilet, including the aforementioned foam shield system.
