Detailed Implementation
[0030] 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.
[0031] This utility model relates to a water outlet device, including a main body 100.
[0032] like Figure 1 , Figure 2 and Figure 3As shown, the main body 100 includes a water inlet 200, a first part 300, a second part 400, and a third part 500. The first part 300 may be configured as a hollow cylindrical structure. The second part 400 is disposed within the first part 300, and a first cavity 310 is defined between the inner wall of the first part 300 and the outer wall of the second part 400. The second part 400 may also be configured as a hollow cylindrical structure, and the third part 500 is disposed within the second part 400. A second cavity 410 is defined between the outer wall of the third part 500 and the inner wall of the second part 400. The third part 500 may also be configured as a hollow cylindrical structure, with its interior hollow to form a third cavity 510. The inlet section 200, the first chamber 310, the second chamber 410, and the third chamber 510 are sequentially connected. An external water supply system, such as a tap water pipe, is connected to the inlet section 200. Water flows sequentially through the inlet section 200, the first chamber 310, the second chamber 410, and the third chamber 510, and is discharged outward from the outlet 511 of the third chamber 510. The end of the inlet section 200 closest to the first section 300 is the outlet end 201. The outlet end 201 of the inlet section 200 faces the outer wall of the second section 400. The direction in which water is sprayed from the outlet end 201 of the inlet section 200 into the first chamber 310 is defined as the first direction. As shown in the figure, the first direction is vertically downward. The connection between the first chamber 310 and the second chamber 410 forms a corner, and the connection between the second chamber 410 and the third chamber 510 forms a corner. The water flow direction from the first cavity 310 to the second cavity 410 and from the second cavity 410 to the third cavity 510 forms at least two points where the flow direction changes. This change in direction can be understood as the water flow deviating from or being opposite to the first direction. For example, as shown in the diagram, water flowing downwards from the first cavity 310 and then changing direction left-right / front-back to flow into the second cavity 410 can form one change in flow direction. Alternatively, water flowing upwards in the second cavity 410 can also form one change in flow direction. Finally, water flowing from the second cavity 410 into the third cavity 510 can also form one change in flow direction.
[0033] When using, such as Figure 4As shown, external water is sprayed into the first cavity 310 from the inlet 200. After entering the first cavity 310, the water flow first impacts the outer wall of the second part 400, dispersing the initial stream of water sprayed from the inlet 200. The water flow is dispersed around the first cavity 310, thus buffering the initial water flow entering the first cavity 310. The dispersed water flow along the first cavity 310. When the water flows from the first cavity 310 into the second cavity 410, it changes direction and impacts the outer wall of the third part 500. In this configuration, if the connection between the first cavity 310 and the second cavity 410 is configured as a single opening, water sprayed into the second cavity 410 will be diverted circumferentially along the third part 500, and then diffuse along the second cavity 410 towards the third cavity 510, where the water flow will be buffered and slowed down. If the connection between the first cavity 310 and the second cavity 410 is configured as multiple openings, the water flow will be dispersed into different openings in the first cavity 310 before changing direction and entering the second cavity 410. The water flow will impact the outer wall of the third part 500 from different directions, where it will again be buffered and slowed down. The water flow from the second cavity 410 into the third cavity 510 undergoes a change of direction for buffering and slowing down. Supplementary water flows into the third cavity 510 and then towards the outlet 511. The relative positions of the first cavity 310, the second cavity 410, and the third cavity 510 fully utilize the space of the main body 100 in the longitudinal (vertical direction in the figure) and transverse (horizontal direction in the figure) directions, effectively extending the flow path of the water. At the same time, in conjunction with the water flow undergoing multiple changes in direction, turbulence and vortices are formed at the bends, increasing the resistance of the water flow during the flow process and causing its kinetic energy to be lost, thereby slowing down the water flow. After being buffered and slowed down, the water is sprayed out of the main body 100. The impact force of the sprayed water flow is effectively reduced, and the water flow sprayed on the object achieves the effect of splash prevention, eliminating the need for the use of traditional aerators.
[0034] This utility model also relates to a faucet that applies the water outlet device in any of the embodiments. When in use, the faucet effectively reduces the impact force of the water jet, preventing splashing and wetting the surrounding environment. It eliminates the need for an aerator, reducing clogging and lowering cleaning difficulty and maintenance costs.
[0035] In one embodiment, such as Figure 2 and Figure 3As shown, a first part 300 surrounds a second part 400. The first part 300 has a first side 301 and a second side 302 facing each other in a first direction, and the second part 400 has a third side 401 and a fourth side 402 facing each other in the same first direction. In the illustrated direction, the first direction is vertical; the upper side of the first part 300 is the first side 301, and the lower side is the second side 302. The upper side of the second part 400 is the third side 401, and the lower side is the fourth side 402. The second part 400 can extend cylindrically from the second side 302 towards the first side 301, and the second side 302 of the first part 300 and the fourth side 402 of the second part 400 can share the same sidewall. There is a certain gap between the first side 301 and the third side 401, and a certain gap between the circumferential inner wall of the first part 300 and the circumferential outer wall of the second part 400. A first cavity 310 is formed at the gap between the first part 300 and the second part 400. The outlet 201 of the water inlet 200 is located on the first side 301. The second part 400 is located below the outlet 201 of the water inlet 200, and the outlet 201 of the water inlet 200 faces the third side 401. The lower part of the second part 400 has a first water inlet 420 for connecting the first cavity 310 and the second cavity 410. Compared with the positional distance between the first water inlet 420 and the third side 401, the first water inlet 420 is closer to the fourth side 402. The first direction of the outlet 201 of the water inlet 200 is vertically downward. Water is sprayed into the first cavity 310 from top to bottom. After the water flow impacts the top outer wall of the second part 400, it disperses in all directions and then flows downward, changing direction from the first water inlet 420 into the second cavity 410. The top shape of the second part 400 can be flat, curved, or other shapes. Based on the above embodiment, the top of the second part 400 is provided with a conical protrusion. The conical protrusion protrudes upwards, with its tip being a sharp point. The outlet end 201 of the water inlet 200 faces the top (third side 401) of the second part 400. After water is sprayed into the first chamber 310 from the water inlet 200, the water flow impacts the end of the conical protrusion of the second part 400 and is dispersed. The water flow obliquely along the top of the second part 400 and then impacts the inner wall of the first part 300. When the water flows obliquely along the top of the second part 400, it deviates from the first direction of the water inlet 200 and forms a buffer after impacting the interior of the first part 300. Preferably, the protrusion on the third side 401 is conical in shape, and the angle between the generatrix at the tip of the protrusion and the axis of rotation ranges from 15° to 33°. The angle can be, but is not limited to, 15°, 17°, 20°, 23°, 25°, 28°, 31°, 33°, etc. The outlet end 201 of the water inlet 200 is on the same central axis as the protrusion. Water is sprayed vertically downwards from the outlet end 201 of the water inlet 200 to the top tip of the second part 400 for relatively uniform dispersion. After being dispersed by the protrusion of the second part 400, the water flow is rectified along the path from the first cavity 310 to the first water outlet 420.The rectified flow direction of water in the first chamber 310 is opposite to the flow direction in the second chamber 410.
[0036] Based on the above embodiment, a plurality of first water inlets 420 are sequentially formed along the circumferential direction at the lower part of the second part 400. Each first water inlet 420 extends in a strip shape from the fourth side 402 toward the third side 401. Figure 5 As shown, the water flow in the first cavity 310 is dispersed into multiple streams through multiple first inlets 420 and enters the second cavity 410. These multiple streams impact the circumferential sidewall of the third part 500, where they are buffered and slowed down. Simultaneously, the streams impact each other against the outer wall of the third part 500 and then converge circumferentially, further buffering the flow velocity. The water then gradually spreads within the second cavity 410 towards the connection point between the second and third cavities 510. The multiple first inlets 420 increase the water flow area of the first and second cavities 310 and allow for circumferential diversion of water from the second part 400 into the second cavity 410. The multiple first inlets 420 ensure water flow and prevent impurities in the water from clogging the first inlets 420 over a long period. When the main body 100 is used vertically, water enters the second cavity 410 from the lower part of the second part 400. The water surrounds the third part 500 in the second cavity 410 and spreads upward, converting kinetic potential energy into gravitational potential energy, and the water flow speed decreases.
[0037] In one embodiment, such as Figure 2 and Figure 3 As shown, the second part 400 is arranged around the third part 500. The third part 500 has a fifth side 501 and a sixth side 502 facing each other in a first direction. In the illustrated direction, the upper side of the third part 500 is the fifth side 501, and the lower side is the sixth side 502. The fifth side 501 and the third side 401 can share the same sidewall, and the sixth side 502 and the fourth side 402 can share the same sidewall. A second water outlet 520 for connecting the second cavity 410 and the third cavity 510 is provided on the third part 500. The second water outlet 520 is closer to the third side 401 than the first water outlet 420, meaning that in the illustrated direction, the height of the second water outlet 520 is higher than the height of the first water outlet 420. The outlet 511 of the third cavity 510 is provided at the bottom of the third part 500 (sixth side 502). After entering the second chamber 410, the water spreads upwards and slows down, then flows from the second inlet 520 into the third chamber 510, where the water flow is redirected and buffered. After entering the third chamber 510, the water flows downwards towards the outlet 511. The flow direction of the water in the second chamber 410 is opposite to that in the third chamber 510.
[0038] Based on the above embodiments, such as Figure 2 and 6As shown, multiple second water inlets 520 are sequentially opened along the circumference of the third part 500, and the second water inlets 520 extend in a strip shape from the fifth side 501 to the sixth side 502. When water flows from the second cavity 410 into the third cavity 510, it is dispersed into multiple streams by the multiple second water inlets 520. After entering the third cavity 510, the multiple streams converge towards the center of the third cavity 510. The second water inlets 520 are distributed along the circumference of the third part 500, forming multiple sets of second water inlets 520 facing each other. After the water flows into the third cavity 510 from every two opposing second water inlets 520, they collide and buffer each other. After the collision, the streams converge at the center of the third cavity 510 to form a mixed flow, which allows the water to be sufficiently decelerated along the radial direction of the third cavity 510 when it enters the third cavity 510 from the second cavity 410. The water then changes direction and flows towards the outlet 511. In addition, multiple second water inlets 520 ensure water flow and prevent impurities in the water from clogging the second water inlets 520 over a long period of time.
[0039] The third cavity 510 contains a rectifier block 512, which is located on the connecting path between the inlet side and the outlet 511 of the third cavity 510. The inlet side of the third cavity 510 is the connection point between the second cavity 410 and the third cavity 510. When water flows and impacts the rectifier block 512, the rectifier block 512 blocks the water flow, thus buffering and slowing it down. One, two, or more rectifier blocks 512 can be provided in the third cavity 510. When at least two rectifier blocks 512 are provided, they are distributed sequentially at intervals along the first direction. The projections of the rectifier blocks 512 in the first direction are staggered. In this embodiment, in the illustrated direction, two rectifier blocks 512 are provided in the third cavity 510, and the two rectifier blocks 512 are distributed vertically. Viewed from above, the two rectifier blocks 512 are distributed horizontally. The rectifier blocks 512 can be integrally formed in the third cavity 510. Each rectifier block 512 is spaced apart in the vertical direction, and each rectifier block 512 can occupy half of the cross-sectional area of the third cavity 510. Water flows from top to bottom in the third cavity 510, impacting each rectifier block 512 and being decelerated step by step.
[0040] Based on the above embodiment, the main body 100 also includes a water outlet cavity 600. The water outlet cavity 600 is located at the bottom of the main body 100 and is connected to the water outlet 511. A plurality of water outlet holes 610 are provided at the bottom of the water outlet cavity 600, and each water outlet 511 is distributed around the water outlet 511 within its top-view projection range. Water flows downwards from the water outlet 511 into the water outlet cavity 600. After entering the water outlet cavity 600, the water impacts and disperses on the bottom surface of the water outlet cavity 600, and then forms multiple fine water jets that spray outwards from each water outlet 511, further effectively reducing the water flow velocity and water pressure, thereby achieving the purpose of water conservation and splash prevention.
[0041] In one embodiment, such asFigure 2 and Figure 3 As shown, the water inlet 200 is provided with a Venturi channel 210. The Venturi channel 210 includes a water inlet area 211, a throat area 212, a negative pressure area 213, and a pressure holding area 214 connected in sequence. An air intake hole 215 is provided on the water inlet 200. The negative pressure area 213 is connected to the external environment through the air intake hole 215. The water inlet area 211 can be configured as a cylindrical cavity with uniform diameter throughout, or as a constricted shape that gradually narrows towards the throat area 212. The throat area 212 can be configured as a cylindrical cavity with uniform diameter throughout, or as a combination of multiple parallel, fine-pore-shaped cavities. The negative pressure area 213 can be configured as a cylindrical cavity with uniform diameter throughout, or as a flared shape that gradually widens away from the throat area 212. The pressure holding area 214 can be configured as a cylindrical cavity with uniform diameter throughout, or as a conical shape. The maximum cross-sectional area of the throat region 212 is smaller than the minimum cross-sectional area of the inlet region 211. The minimum cross-sectional area of the negative pressure region 213 is larger than the maximum cross-sectional area of the throat region 212. The maximum cross-sectional area of the pressure-holding region 214 is smaller than the minimum cross-sectional area of the negative pressure region 213. The end of the pressure-holding region 214 furthest from the negative pressure region 213 serves as the outlet end 201 of the inlet section 200. External water enters from the inlet region 211 and flows sequentially through the inlet region 211, throat region 212, negative pressure region 213, and pressure-holding region 214. According to the Venturi effect, negative pressure is created when water passes through the negative pressure region 213, and external air is drawn into the negative pressure region 213 through the air intake hole 215 for water-air mixing. The water-air mixture balances the pressure on the upper and lower sides when it passes through the pressure-holding region 214.
