DETAILED DESCRIPTION

[0029] 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.

[0030] The present invention relates to a pulse water outlet device, comprising a water passage 101, an air suction passage 102, a rebound chamber 103 and a rectifying passage 104.

[0031] As shown in Figures 1, 2 and 3, the water passage 101, the rebound chamber 103 and the rectifying channel 104 can be distributed and connected in sequence on the same axis. The interior of the water passage 101 includes a negative pressure area 105, and the negative pressure area 105 forms a negative pressure when water flows through the water passage 101. The air suction channel 102 is connected to the negative pressure area 105, and the negative pressure area 105 is connected to the external environment through the air suction channel 102, or the negative pressure area 105 is connected to an external air supply device through the air suction channel 102. One or more air suction channels 102 can be set, and multiple air suction channels 102 ensure the air intake. The water passage 101 can be composed of a conventional venturi tube, and the interior of the venturi tube is sequentially divided into a constriction section, a throat section, a flaring section and a mixing section along the water flow direction, and a negative pressure area 105 is formed at the throat section. When the negative pressure area 105 forms a negative pressure, the air of the external environment can be sucked into the negative pressure area 105 through the air suction channel 102. Along the water flow direction, water flows through the water channel 101, the rebound chamber 103 and the rectifying channel 104 in sequence. The rebound chamber 103 is located between the downstream end of the water channel 101 and the upstream end of the rectifying channel 104. Among them, the inner diameter of the downstream end of the water channel 101 is A, the inner diameter of the rebound chamber 103 is B, and the inner diameter of the upstream end of the rectifying channel 104 is C, which satisfies B>A>C. Due to the instantaneous reduction of space from the rebound chamber 103 to the rectifying channel 104, the transition position between the rebound chamber 103 and the rectifying channel 104 will have a blocking effect on water, causing the water to rebound and flow back in the rebound chamber 103 in the direction of the water channel 101. In addition, the maximum injection range of the liquid entering the negative pressure area 105 from the upstream of the water channel 101 is not greater than the inner diameter of the downstream end of the water channel 101, and the liquid can be tangent to the inner wall of the water channel 101 from the negative pressure area 105 to the downstream side of the negative pressure area 105. Moreover, the maximum injection range of the liquid is not greater than or less than the inner diameter of the upstream end of the rectifying channel 104. This can reduce the resistance of the liquid flowing from the negative pressure area 105 through the bucket to the downstream end of 101, and after entering the rebound chamber 103, part of the liquid will impact the upstream end of the rectifying channel 104 to form a rebound.

[0032] In actual use, as shown in FIG5 , water enters the water passage 101 and forms a negative pressure when flowing through the negative pressure zone 105. The negative pressure zone 105 sucks the air from the external environment into the negative pressure zone 105 through the air intake channel 102. Air and water are mixed in the water passage 101 to form a fluid. When the fluid flows from the negative pressure zone 105 to the downstream end of the water passage 101, the fluid can directly pass through the downstream section of the water passage 101 and enter the rebound chamber 103. After passing through the rebound chamber 103, part of the water vapor impacts the upstream end of the rectification channel 104, rebounds to the downstream end of the water passage 101, and the water vapor is mixed at the downstream end of the water passage 101. After mixing, it re-enters the rebound chamber 103 and flows into the rectification channel 104, and finally sprays out from the downstream end of the rectification channel 104. At the beginning of water flow, due to the increase in the internal negative pressure of the negative pressure zone 105, the air intake increases, the flow rate increases, and the water vapor enters the rebound chamber 103 and rebounds back to the water channel 101. The flow rate is large, which leads to an increase in the forward flow resistance of the liquid (the direction of water flowing from the water channel 101 to the rectifying channel 104 is the forward direction). After the forward flow resistance increases, the flow rate of water to the downstream end of the water channel 101 slows down, the negative pressure of the negative pressure zone 105 decreases, and the air intake decreases, so that the water flow rate and flow rate entering the rebound chamber 103 are reduced, and then the water vapor rebounding back to the flow channel decreases, and the forward flow resistance of the liquid decreases. At this time, the speed of the forward flow of water vapor becomes faster again. At this time, the negative pressure effect of the negative pressure zone 105 becomes larger again, resulting in an increase in the air intake. After the air intake increases, the state of increased forward flow resistance is repeated. In this way, the resistance to the forward flow of water vapor is cyclically changed between increasing and decreasing, and the water ejected from the rectifying channel 104 generates an oscillating pulse, and finally a pulse flushing effect is achieved. The pulse water outlet device can be applied to water-using equipment such as faucets and showers. The present invention also relates to a toilet, such as Figure 8 As shown, the toilet uses a pulse water outlet device. The pulse water outlet device can be connected to the water tank on the toilet. The pulse water formed by the pulse water outlet device is used to flush the toilet cavity of the toilet, which effectively improves the cleaning effect. There is no need to increase the flushing force by increasing the flow rate of water supply, which reduces the waste of water resources of the product, and the impact of water and gas on the toilet cavity after mixing can avoid splashing. Alternatively, the pulse water outlet device can be connected to the foam shield on the toilet. The foaming agent can be fully mixed and foamed in the pulse water outlet device, and the formed foam is sprayed into the toilet cavity of the toilet in the form of pulse foaming, which can effectively increase the foaming amount of the foam shield.

[0033] In some embodiments of the present invention, as shown in FIG. 2, FIG. 3 and FIG. 4, the pulse water outlet device further includes an inlet pipe 200, a flow pipe 300 and a rectifying pipe 400 connected in sequence. A water inlet channel 210 is provided inside the water inlet pipe 200. The water inlet channel 210 can be provided in a cylindrical shape, or in a shape such as a flared shape that gradually increases from the upstream end of the water inlet pipe 200 toward the flow pipe 300 as shown in the figure. A negative pressure area 105 is formed in the flow pipe 300. A diverter 500 is provided between the water inlet pipe 200 and the flow pipe 300. In this embodiment, the diverter 500 is provided in a disc shape, which is adapted to the shape of the upstream end of the flow pipe 300. The diverter 500 can also be provided in a block shape or other shapes. The diverter 500 can also be integrally formed at the upstream end of the flow pipe 300. A plurality of diverter holes 510 are provided on the diverter 500. The number of the diverter holes 510 can be two, three or more, and the shape of the diverter holes 510 can be various regular shapes such as round, square, polygonal or other irregular shapes. The aperture of each diverter hole 510 is smaller than the inner diameter of the downstream end of the water inlet channel 210, and the sum of the radial cross-sectional areas of each diverter hole 510 is smaller than the radial cross-sectional area of ​​the downstream of the water inlet channel 210. One end of each diverter hole 510 is connected to the downstream end of the water inlet channel 210, and the other end is connected to the negative pressure zone 105. Each diverter hole 510 and the interior of the flow tube 300 together form a water passage 101. Among them, the maximum distance dimension between the diverter holes 510 that are relatively farthest in the radial direction is D, which satisfies: D≤A, D>C. As shown in Figure 6, multiple diverter holes 510 are distributed on the diverter 500 along a virtual circumference, and the diameter dimension of the virtual circumference is D, and the diameter of the virtual circumference is the maximum distance dimension D between the diverter holes 510. The size is set in this way to reduce the axial impact rebound between the water and the inner wall of the water passage 101 when the water enters the negative pressure area 105 through each diversion hole 510 and flows toward the downstream end of the water passage 101, so that the water vapor flows axially toward the downstream end of the water passage 101.

[0034] The air suction channel 102 is provided on the side wall of the flow tube 300 and corresponds to the position of the negative pressure zone 105. A rebound chamber 103 is defined between the flow tube 300 and the rectifying tube 400, and the rectifying channel 104 is formed in the rectifying tube 400. When in use, water enters the water inlet channel 210 from the upstream end of the water inlet pipe 200. The water is diverted from the water inlet channel 210 through each diverting hole 510 and then transported to the negative pressure zone 105. When the water flows through the water inlet channel 210, the diverting hole 510, the negative pressure zone 105 and the rebound chamber 103, a Venturi effect is generated, and a negative pressure is formed in the negative pressure zone 105 to achieve air suction. The setting of the diverter hole 510 can divert and disperse the water, and a large negative pressure can be formed in the negative pressure area 105. At the same time, the diverter 500 can have a certain blocking effect on the water vapor flowing back from the rebound chamber 103, ensuring that the resistance to the forward flow of the water vapor changes cyclically between increasing and decreasing. The ordinary Venturi structure must reduce the flow rate by shrinking the aperture to increase the negative pressure and thus increase the suction volume, but in this embodiment, a diverter is set, and the diverter can achieve a large suction volume while ensuring a large flow rate.

[0035] Among them, the interior of the rectifier tube 400 is provided with a first channel 410 and a rectifier channel 104. The first channel 410 and the rectifier channel 104 are coaxially arranged and interconnected. The inner diameter of the first channel 410 is larger than the inner diameter of the rectifier channel 104, and the transition position between the first channel 410 and the rectifier channel 104 is stepped. The downstream end of the flow tube 300 is plugged into the first channel 410, and a sealing ring can be installed between the two for sealing. The transition position between the downstream end of the flow tube 300 and the first channel 410 also forms a step. The space between the downstream end of the flow tube 300 and the upstream end of the rectifier channel 104 of the first channel 410 forms a rebound chamber 103. The inner diameters of the rebound chamber 103 are equal at all places, and the inner diameters of the rectifier channel 104 are equal at all places. After water enters the rebound cavity 103 from the flow passage, it impacts the table surface at the step position of the rebound cavity 103 and the rectifying channel 104 , causing water vapor to rebound and flow back toward the water passage 101 .

[0036] In some specific embodiments of the present invention, as shown in FIG. 2 and FIG. 3, the interior of the flow tube 300 is divided into a negative pressure zone 105 and a second channel 310 in sequence. The negative pressure zone 105 and the second channel 310 are coaxially arranged. The diverter 500 is installed on the end of the negative pressure zone 105 away from the second channel 310. The inner diameter of the negative pressure zone 105 is larger than the inner diameter of the second channel 310, ensuring that the space expands instantly after the water passes through the diverter 500 to form a negative pressure. The second channel 310 can be set to have equal diameters at all locations. The maximum injection range of the liquid when the water channel 101 enters the negative pressure zone 105 from the upstream is not greater than the inner diameter of the second channel 310. The flow tube 300 is inserted into the rectifier tube 400. It can also be that, as shown in FIG. 7, the second channel 310 includes a first section 311 and a second section 312, and the first section 311 is arranged between the negative pressure zone 105 and the second section 312. The first section 311 is in a gradually narrowing shape from the negative pressure area 105 to the second section 312, that is, the axial cross section of the first section 311 is conical. The end of the second section 312 away from the first section 311 is the downstream end of the water passage 101. The inner diameter of the first section 311 is larger than the maximum injection range of the liquid. The setting of the first section 311 can eliminate or reduce the radial impact between the water and the inner wall of the second channel 310 when the water enters the second channel 310 from the negative pressure section 105. After the water vapor rebounds from the rebound cavity 103, it mixes in the second section 312 and forms a flow resistance.

[0037] In some specific embodiments of the present invention, as shown in FIG. 1 and FIG. 2 , the outer wall of the flow tube 300 is provided with a first connecting column 330 protruding in the radial direction. The position of the first connecting column 330 is aligned with the negative pressure zone 105. The air intake channel 102 is provided in the first connecting column 330. A first clamp 220 is provided at one end of the water inlet pipe 200, and the first clamp 220 is provided in a C-shaped notch from the downstream end of the water inlet pipe 200. The downstream end of the water inlet pipe 200 is sleeved on the upstream end of the flow tube 300, and the first clamp 220 is clamped on the first connecting column 330, so that the water inlet pipe 200 and the flow tube 300 are relatively fixed. A sealing ring can be installed between the inner wall of the downstream end of the water inlet pipe 200 and the outer wall of the upstream end of the flow tube 300 for sealing. The cooperation between the first clamp 220 and the first connecting column 330 is used for fixing the water inlet pipe 200 and the flow pipe 300 on the one hand, and can limit the axial insertion depth of the water inlet pipe 200 relative to the flow pipe 300 on the other hand, and at the same time can ensure that the water inlet pipe 200 will not block the air intake channel 102 after installation, thereby ensuring that the air intake channel 102 can be unobstructed.

[0038] Further, as shown in Fig. 3 and Fig. 4, a first step 340 is provided inside the upstream end of the flow tube 300, and the diverter 500 is overlapped on the first step 340 in a plate shape. The outer contour shape of the diverter 500 is adapted to the shape of the inner wall of the upstream end of the flow tube 300. A second step 230 is provided inside one end of the water inlet pipe 200. After the water inlet pipe 200 is sleeved onto the flow tube 300, the diverter 500 is clamped between the second step 230 and the first step 340, thereby fixing the diverter 500.

[0039] As shown in FIG2 , the outer wall of the flow tube 300 is provided with a second connecting column 350 protruding in the radial direction. The position of the second connecting column 350 can be aligned with the second channel 310. The upstream end of the rectifier tube 400 is provided with a second clamping opening 420 in the shape of a C-shaped notch. One end of the rectifier tube 400 is sleeved on the flow tube 300, and the second clamping opening 420 is clamped on the second connecting column 350, so that the rectifier tube 400 and the flow tube 300 are relatively fixed, and at the same time, the insertion depth of the flow tube 300 relative to the rectifier tube 400 can be limited, so as to ensure the axial size of the formed rebound cavity 103.

[0040] In some embodiments of the present invention, as shown in FIG. 1, FIG. 2 and Figure 8 As shown, the outer wall of the rectifier tube 400 is provided with external threads. The pulse water outlet device can be installed on the toilet bowl through the external threads on the rectifier tube 400.

[0041] As shown in the figure, the water inlet pipe 200 is provided with a branch pipe 600 connected to the water inlet channel 210. The branch pipe 600 can extend outward from the outer wall of the water inlet pipe 200, and the branch pipe 600 is used to connect the foam shield on the toilet. The foaming agent of the foam shield is input into the water inlet pipe 200 through the branch pipe 600 and mixed with water, and finally forms a pulse effect for spraying. Compared with the foaming structure of the conventional foam shield, the foaming agent can be fully foamed under the rebound pulse of the rebound chamber 103, and only less foaming agent is needed for the same foaming amount.
