DETAILED DESCRIPTION

[0029] The embodiments of the present application will be described in detail below, examples of which are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0030] The present application relates to a kind of water outlet device, including main body 100 and slip sleeve 300.

[0031] As Figure 1 and Figure 2As shown, the main body 100 can be provided as a pipe body or the like. A Venturi channel 200 is arranged inside the main body 100. The Venturi channel 200 comprises a water inlet section 210, a throat section 220 and an air suction section 230 which are sequentially communicated. The water passage area of the water inlet section 210 is larger than the water passage area of the throat section 220. The water passage section can be provided as a cylindrical hollow structure with a uniform diameter; or the water passage section can be provided as a necking structure which gradually narrows towards the throat section 220, and the minimum water passage area of the water passage section is larger than the water passage area of the throat section 220. The throat section 220 can be a hollow cylindrical structure; or the throat section 220 can be formed by a plurality of mutually parallel through holes, and the total water passage area of the through holes is the water passage area of the throat section 220. The water passage area of the throat section 220 is smaller than the water passage area of the air suction section 230. The air suction section 230 can be a cylindrical hollow structure with a uniform diameter; or the air suction section 230 can be provided as a flaring structure which gradually expands away from the throat section 220, and the minimum water passage area of the air suction section 230 is larger than the water passage area of the throat section 220. An air suction hole 231 is arranged on the sidewall of the main body 100 at a position corresponding to the air suction section 230. The air suction hole 231 penetrates the sidewall of the main body 100, and the air suction hole 231 directly communicates the air suction section 230 with the external environment of the main body 100. A sliding sleeve 300 is sleeved on the main body 100, and the sliding sleeve 300 can move relative to the main body 100. A gas sealing structure is arranged between the sliding sleeve 300 and the main body 100, and the state of the gas sealing structure changes with the movement of the sliding sleeve 300. When the sliding sleeve 300 moves relative to the main body 100 in one direction, the gas sealing structure gradually increases the air passage amount of the air suction hole 231. When the sliding sleeve 300 moves relative to the main body 100 in the other direction, the gas sealing structure gradually reduces the air passage amount of the air suction hole 231, and the air passage amount of the air suction hole 231 can be reduced to zero. In use, external water enters the main body 100, and flows along the water inlet section 210, the throat section 220 and the air suction section 230 in sequence. According to the Venturi effect, a negative pressure is formed in the air suction section 230, and the negative pressure effect causes the air in the external environment of the main body 100 to be sucked into the air suction section 230 through the air suction hole 231, so that the water and air are mixed. In the case of constant water supply, the position of the sliding sleeve 300 on the main body 100 is adjusted, the air passage amount of the air suction hole 231 is infinitely changed by the gas sealing structure, the water and air mixing ratio is changed, different water spraying effects are achieved, and the operation is convenient and the structure is simple.

[0032] The water outlet device can be applied to a faucet, a spray gun, a shower nozzle and the like. The utility model also relates to a shower head, and the water outlet device is applied to the shower head. By changing the air suction amount through the water outlet device, different spraying and massaging effects can be achieved, and different water use requirements of users can be met. For example, Figure 6As shown, the main body 100 further comprises an oscillation channel 600. The oscillation channel 600 is in communication with the Venturi channel 200 and located on the downstream side of the Venturi channel 200. The oscillation channel 600 is provided with a blocking part 610 for hindering the water flowing to the downstream side in the oscillation channel 600 and making the water flow back to the Venturi channel 200. During the water use, the water flows in the oscillation channel 600. Part of the water directly flows out through the downstream end of the oscillation channel 600, and part of the water is hindered by the blocking part 610 and then flows back to the suction section 230. The backflowing water mixes with the water in the oscillation channel 600 and collides. The backflowing water produces resistance to the suction air, and the air suction amount of the water outlet device gradually decreases. At the same time, the pressure of the area near the downstream end of the oscillation channel 600 gradually decreases. When the pressure at the downstream end of the oscillation channel 600 decreases to a certain value, the water in the oscillation channel 600 flows to the downstream end of the oscillation channel 600 under the pressure of the water and air in the suction section 230. In turn, the air suction amount of the water outlet device gradually increases, and the water outlet amount of the downstream end of the oscillation channel 600 increases. At the same time, part of the water flows back through the blocking part 610, and the process is repeated. Finally, the water is pulsed in the form of granular water. Similar to the water outlet device disclosed in 202411220925.7 and the shower head provided with the water outlet device. On the basis of the above, the sliding sleeve 300 and the air tight structure are configured to change the air suction amount to change the pulse frequency.

[0033] The sliding sleeve 300 can be directly sleeved on the main body 100, or a guide groove or other guide structure is arranged between the sliding sleeve 300 and the main body 100, and the sliding sleeve 300 translates relative to the main body 100. In an embodiment, as shown in Figure 2 The sliding sleeve 300 is provided with an internal thread, and the main body 100 is provided with an external thread. After the sliding sleeve 300 is sleeved on the main body 100, the sliding sleeve 300 and the main body 100 are in threaded connection. The sliding sleeve 300 rotates relative to the main body 100, and then the two axially translate relative to each other.

[0034] The air tight structure can have different structures, such as a plug, which controls the opening degree of the end of the air suction hole 231 located on the outer side wall of the main body 100, thereby controlling the air suction amount.

[0035] In an embodiment, as shown in Figure 2As shown, the first sealing ring 410 is sleeved on the main body 100. The sliding sleeve 300 is connected with the first sealing ring 410. When the sliding sleeve 300 moves, the first sealing ring 410 moves relative to the main body 100. The inner ring of the first sealing ring 410 is tightly attached to the outer wall of the main body 100. The path of the first sealing ring 410 moving along with the sliding sleeve 300 passes the end of the air inlet hole 231 on the outer wall of the main body 100. In the direction shown in the figure, when the first sealing ring 410 is moved to the left by the sliding sleeve 300, the first sealing ring 410 leaves the end of the air inlet hole 231, and at this time, the air volume of the air inlet hole 231 reaches the maximum. As shown in the figure, Figure 3 When the first sealing ring 410 is moved to the right by the sliding sleeve 300, the first sealing ring gradually approaches the end of the air inlet hole 231, gradually covers the end of the air inlet hole 231, and gradually reduces the air volume of the air inlet hole 231, until the end of the air inlet hole 231 is completely covered by the first sealing ring 410, and then the air inlet hole 231 is blocked and cannot ventilate. The first sealing ring 410 constitutes the above-mentioned air-tight structure.

[0036] Based on the above-mentioned embodiment, further, the outer wall of the main body 100 is provided with a first taper surface 101. One end of the air inlet hole 231 is provided on the first taper surface 101. The two ends of the first taper surface 101 are small-diameter end and large-diameter end respectively, and the outer diameter of the small-diameter end is smaller than that of the large-diameter end. Compared with the small-diameter end of the first taper surface 101, the air inlet hole 231 is closer to the large-diameter end of the first taper surface 101. That is, the distance between the end of the air inlet hole 231 and the large-diameter end of the first taper surface 101 is smaller than the distance between the end of the air inlet hole 231 and the small-diameter end of the first taper surface 101. The first sealing ring 410 slides along the first taper surface 101. The first sealing ring 410 can be made of silica gel, rubber or other materials with certain elasticity. The first sealing ring 410 expands and contracts along with the first taper surface 101. When the first sealing ring 410 moves from the small-diameter end to the large-diameter end, the first sealing ring 410 gradually expands, so that the first sealing ring 410 is more tightly sleeved on the outer wall of the main body 100, and the end of the air inlet hole 231 is more tightly and stably covered or blocked. The first clamping groove 310 is arranged on the inner wall of the sliding sleeve 300. The first clamping groove 310 is arranged along the circumference of the sliding sleeve 300, that is, the first clamping groove 310 is in the form of a ring. The first sealing ring 410 is clamped in the first clamping groove 310. The sliding sleeve 300 drags the first sealing ring 410 to move through the first clamping groove 310.

[0037] In an embodiment, as shown in the figure, Figure 4As shown, the outer wall of the sleeve 300 and the main body 100 defines an air inlet cavity 500. The inner wall of the sleeve 300 can be provided with a concave cavity, and the concave cavity and the outer wall of the main body 100 constitute the air inlet cavity 500. The main body 100 is sleeved with a second sealing ring 420. The air inlet hole 231 communicates with the air inlet cavity 500. The air inlet hole 231 can be provided with an end on the cavity wall of the air inlet cavity 500. One side of the air inlet cavity 500 is open to form an air inlet 510. The air inlet 510 can be provided around the main body 100, and the air inlet 510 is in the form of a circular annular opening. The air inlet 510 is directed towards the second sealing ring 420. The second sealing ring 420 is fixed on the main body 100, and a convex edge 102 can be provided on the main body 100, and the second sealing ring 420 is fixed by abutting against the convex edge 102. When the sleeve 300 moves from left to right, the air inlet 510 can gradually approach the second sealing ring 420, the distance between the air inlet 510 and the second sealing ring 420 gradually decreases, until the air inlet 510 abuts against the second sealing ring 420, and the air inlet 510 is blocked by the second sealing ring 420. The air in the external environment flows into the air inlet cavity 500 through the air inlet 510, the air inlet cavity 500, and the air inlet hole 231 in sequence and is then sucked into the air inlet section 230. As shown in Figure 5 When the air inlet 510 gradually approaches the second sealing ring 420, the amount of air sucked into the air inlet cavity 500 through the air inlet 510 gradually decreases, and the air flow of the air inlet hole 231 gradually decreases. After the second sealing ring 420 blocks the air inlet 510, the air flow of the air inlet hole 231 is zero. As shown in Figure 4 When the sleeve 300 moves from right to left, the air flow of the air inlet 510 increases, and the air flow of the air inlet hole 231 gradually increases. Until the air inlet 510 moves away from the second sealing ring 420, the air flow of the air inlet 510 is the maximum air flow of the air inlet hole 231. The cooperation of the air inlet cavity 500 and the second sealing ring 420 constitutes an air-tight structure.

[0038] Based on the above embodiment, the cavity wall of the sleeve 300 is a second tapered surface 520. The inner diameter of the second tapered surface 520 gradually increases towards the air inlet 510. The air inlet 510 is located at the large diameter end of the second tapered surface 520. One end of the air inlet hole 231 is directed towards the second tapered surface 520. When the sleeve 300 slides to the right, the distance between the second tapered surface 520 and the end of the air inlet hole 231 decreases, which also reduces the air flow of the air inlet hole 231.

[0039] Based on the above embodiment, as shown in Figure 4 and Figure 5 The third sealing ring 430 is installed on the sleeve 300. The third sealing ring 430 abuts against the outer wall of the main body 100. The third sealing ring 430 seals the side of the air inlet cavity 500 away from the air inlet 510, and air can only enter the air inlet cavity 500 through the air inlet 510 to ensure the stability when adjusting the air flow of the air inlet hole 231.
