DETAILED DESCRIPTION

[0038] Embodiments of the present invention are described in detail below, examples of which 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 intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0039] The present invention relates to a water outlet structure, comprising a venturi pipe 100 , a one-way flow channel 200 and a water outlet channel 300 .

[0040] like Figure 1 , Figure 2 and Figure 6 As shown, the venturi pipe 100 includes a water inlet channel 110, a throat 120 and an air inlet chamber 130. The water inlet channel 110, the throat 120 and the air inlet chamber 130 are connected in sequence, and the throat 120 is in a conical shape, and the throat 120 gradually narrows from the water inlet channel 110 to the air inlet chamber 130. In this embodiment, a section of the throat 120 close to the water inlet channel 110 is conical, and a section close to the air inlet chamber 130 is cylindrical. The water inlet channel 110 is connected to external tap water, and water flows from the water inlet channel 110 through the throat 120 into the air inlet chamber 130. One end of the one-way flow channel 200 is connected to the atmosphere, and the other end is connected to the air inlet chamber 130. The water outlet channel 300 is connected to the air inlet chamber 130. Water is transported from the Venturi pipe 100 to the water outlet channel 300. When the water flows through the air inlet chamber 130, negative pressure is formed. The air in the external environment is transported from one end (the air inlet end 210) of the one-way flow channel 200 to the air inlet chamber 130 in one direction. The gas and water are mixed in the air inlet chamber 130 and discharged through the water outlet channel 300 to achieve a pressurization effect. During the initial water inlet or water supply process, especially at the moment when the water in the Venturi pipe 100 is cut off, a huge pressure will be generated, which will push the water in the air inlet chamber 130 to the one-way flow channel 200. The direction of gas inflow is the forward flow direction of the one-way flow channel 200. The one-way flow guidance effect of the one-way flow channel 200 will prevent the water in the air inlet chamber 130 from being transported out of the one-way flow channel 200, thereby avoiding the occurrence of water leakage. That is, in normal use or when the pressure suddenly changes, the one-way flow channel 200 can effectively prevent water from overflowing along the one-way flow channel 200 to the air inlet end 210, causing the air to be unable to be inhaled and the air intake and pressurization function to fail. Under the effect of the one-way overflow prevention of the internal structure of the one-way flow channel 200, the opening of the air inlet end 210 can be set to a relatively large size, which can meet the air inhalation function while effectively avoiding the sharp noise caused by the small opening when the gas flows through the air inlet end 210, and has an overall efficient noise reduction effect.

[0041] In some specific embodiments, Figure 2 As shown, the interior of the one-way flow channel 200 is a Tesla valve structure. Under the one-way flow guidance of the Tesla valve structure, the gas can prevent water from overflowing, and can effectively avoid turbulence and reduce the generation of gas noise. Due to the multi-bend structure of the Tesla valve structure, the noise generated in the one-way flow channel 200 can be reflected layer by layer and gradually weakened, effectively reducing the transmission of noise from the air inlet end 210 of the one-way flow channel 200 to the outside. The opening of the air inlet end 210 of the Tesla valve structure can be set to a larger size, thereby reducing the generation of noise.

[0042] In some specific embodiments, Figure 5 As shown, a one-way valve 220 is installed inside the one-way flow channel 200. The one-way valve 220 controls the one-way flow of the fluid to prevent water from overflowing to the air inlet end 210 of the one-way flow channel 200, thereby achieving the purpose of increasing the design size of the opening of the air inlet end 210.

[0043] In some embodiments, the maximum water flow cross-sectional area of ​​the throat 120 is S1, and the maximum water flow cross-sectional area of ​​the end of the water outlet channel 300 close to the air inlet cavity 130 is S2, which satisfies: S1 is less than S2. The maximum water flow cross-sectional areas corresponding to the water inlet channel 110, the throat 120 and the air inlet cavity 130 change from large to small and then to large, which can ensure that when water is transported from the venturi pipe 100 to the water outlet channel 300, a negative pressure is formed in the air inlet cavity 130, and at the same time reduce or avoid water overflowing to the one-way flow channel 200. Specifically, as Figure 2 and Figure 6 As shown, the length of the water-passing section of the throat 120 is D and the width is G. The length of the water-passing section of the end of the water outlet channel 300 close to the air inlet cavity 130 is F and the width is H; the parameters satisfy: D≤F, G<H. Further, the length of the water-passing section of the air inlet cavity 130 is E, which satisfies D<E<3D.

[0044] In some embodiments, the air inlet direction of the one-way flow channel 200 relative to the air inlet cavity 130 is set according to the actual spatial position of the product. The water flow direction of the water inlet side of the air inlet cavity 130 and the air flow direction of the air inlet side thereof are intersecting directions. The side of the air inlet cavity 130 connected to the throat 120 is the water inlet side, and the side of the air inlet cavity 130 connected to the one-way flow channel 200 is the air inlet side. The water flow direction of the air inlet side is A1, and the air flow direction of the air inlet side is A2. A1 intersects with A2. Figure 2 As shown in the figure, the angle a1 between A1 and A2 is an acute angle. Figure 3 As shown in FIG. 4 , the angle a2 between A1 and A2 is a right angle. As shown in FIG. 4 , the angle a3 between A1 and A2 is an obtuse angle. Under the action of the one-way flow channel 200 , the above angle settings can achieve air intake while preventing water overflow.

[0045] In some embodiments, Figure 6 As shown, the air inlet cavity 130 is provided with an air inlet 131 connected to the one-way flow channel 200, a water inlet 132 connected to the throat 120, and a water outlet 133 connected to the water outlet channel 300. The section connecting the water outlet channel 300 and the water outlet 133 is a straight pipe section 310, and the straight pipe section 310 extends in a straight pipe body. The straight pipe section 310 and the water inlet 132 are on the same straight line. Among them, in the water flow direction of the air inlet cavity 130 (the left and right horizontal direction in the figure), the distance between the air inlet 131 and the water inlet 132 is , the distance between the water inlet 132 and the water outlet 133 is , the length of the straight pipe section 310 is , which satisfies: The position of the air inlet 131 is within this range, which can ensure that the negative pressure formed in the air inlet cavity 130 when the water flows through the air inlet cavity 130 satisfies the air suction of the one-way flow channel 200 and the flow acceleration effect in the water outlet channel 300 after the water and air are mixed and pressurized.

[0046] In some embodiments, Figure 6 As shown, the connection between the water inlet channel 110 and the throat 120 is in a tapered shape from large to small. When the water flow transitions from the water inlet channel 110 to the throat 120, the water flow is guided by the tapered connection, and the water flow can flow smoothly into the throat 120.

[0047] In some embodiments, a water outlet branch 320 is provided at the water outlet end of the water outlet channel 300, or, Figure 2 As shown, the water outlet end of the water outlet channel 300 is divided into a plurality of parallel water outlet branches 320. The arrangement of the plurality of water outlet branches 320 can disperse and evenly discharge water.

[0048] The present invention also relates to a shower device, which uses the above-mentioned water outlet structure. The shower device can be a shower head, etc. The above-mentioned water outlet structure can effectively increase pressure and reduce noise during the shower process, thereby reducing the impact of sharp noise on users during showering.

[0049] Specifically, Figure 7 and Figure 8 As shown, the shower device includes a nozzle 400. The nozzle 400 may be in the shape of a disc. The nozzle 400 is provided with one or more water outlet structures. When multiple water outlet structures are provided, the water inlet channels 110 of each water outlet structure are connected in parallel to the same water supply pipeline 410. The water supply pipeline 410 is connected to a tap water or hot water device. The water supply pipeline 410 diverts water to each water inlet channel 110, and each water outlet structure works synchronously, and each one-way flow channel 200 is used to synchronously inhale air, and the air intake volume is large, which effectively ensures the pressurization effect. More importantly, multiple one-way flow channels 200 can greatly reduce the noise generation while increasing the air intake volume. A water outlet chamber 420 is provided on the nozzle 400, and a plurality of fine holes 430 are opened on the water outlet chamber 420. The water outlet channels 300 of each water outlet structure are connected to the water outlet chamber 420. After the water is collected in the water outlet chamber 420, it is sprayed outward through each fine hole 430.
