[0031] 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.

[0032] In some specific embodiments of this utility model, a water outlet device is provided, such as a bathroom shower or kitchen water device like a faucet or showerhead, or a spray gun or bidet in a smart toilet. This water outlet device not only enables pulsed water flow, but also allows the user to adjust the amplitude and frequency of the pulsed water flow, thus providing multiple different pulsed water flows from a single device to meet various user needs.

[0033] refer to Figure 1 , Figure 2 , Figure 3 and Figure 8 In some specific embodiments of this utility model, the water outlet device includes a housing 100 and an adjusting member 200. The housing 100 is provided with a space for water to flow through. The housing 100 includes an air intake section 130, a connecting section 140, an oscillation section 150, and a mixing section 160 connected in sequence. The contraction section 120 extends from the end of the air intake section 130 away from the connecting section 140 into the air intake section 130. The contraction section 120 refers to a channel whose water passage area gradually decreases along the water inlet direction, including an inlet end and an outlet end 1221. Specifically, the outlet end 1221 extends into the air intake section 130 and faces the connecting section 140, so that the water flow output from the outlet end 1221 can flow from the connecting section 140 and enter the mixing section 160 after passing through the oscillation section 150. The air intake section 130 is provided with an air hole 131 connecting the internal space of the air intake section 130 and the air source. The inner wall surface 152 of the oscillation section 150 away from the connecting section 140 is provided with a water outlet 151, and the water outlet area of ​​the water outlet 151 is smaller than the area of ​​the inner wall surface 152. The oscillation section 150 and the mixing section 160 are connected through the water outlet 151. The end of the mixing section 160 facing away from the water outlet 151 is provided with a water outlet 161, which is perpendicular to the mixing section 160.

[0034] At least a portion of the adjusting member 200 is disposed in the housing 100, and the adjusting member 200 is movable within the housing 100 to change the water passage area of ​​the connecting section 140.

[0035] It should be specifically noted here that "the outlet end 1221 faces the connecting section 140" means that the outlet end 1221 is exposed in the air intake section 130, and there is a certain gap between the outlet end 1221 and the connecting section 140 (see reference). Figure 2 ), or at the same time as the outlet end 1221 and the connecting section 140 are connected, the air intake port is exposed in the air intake section 130 (see reference). Figure 8 It is only necessary to ensure that the water flow at the outlet 1221 and the external gas can flow directly to the connecting section 140. Furthermore, the projection of the connecting section 140 along the water inlet direction coincides with the outlet 151, so that the water flow can enter from the connecting section 140, pass through the oscillation section 150, and then directly enter the mixing section 160.

[0036] It is understandable that the water outlet 161 is perpendicular to the mixing section 160, which means that the water outlet direction of the water outlet 161 is perpendicular to the water inlet direction. Therefore, the end of the mixing section 160 facing away from the water outlet 161 also includes a bottom wall surface 162.

[0037] The working process and principle of the water outlet device provided in the specific embodiments of this utility model are described in detail below:

[0038] When the user drives the adjusting component 200 to stop a portion of it at the target position in the housing 100, the cross-sectional area of ​​the connecting section 140 no longer changes. When the water flow (with solid arrows) enters the housing 100, it first flows through the contraction section 120, where the flow velocity gradually increases. When the water flow is ejected from the outlet 1221 of the contraction section 120, due to the increased flow velocity, a negative pressure is formed near the outlet 1221 due to the Venturi principle, thereby reducing the air pressure in the intake section 130. At this time, the gas from the external air source enters the intake section 130 through the air hole 131 and forms a jet with the water flow, which is then ejected from the connecting section 140. After passing through the oscillation section 150, it directly enters the mixing section 160 from the outlet 151. When the water flow impacts the bottom wall surface 162, it further mixes with the gas. The mixed portion... One jet is ejected from the outlet 161, while the other jet forms a rebound flow with the opposite direction to the inlet flow. When the rebound flow returns to the outlet 151, it is injected into the oscillation chamber 150 and fills the oscillation chamber 150. Since the rebound flow is a fully mixed flow in the mixing section 160, its flow velocity is lower than that of the jet entering from the connecting section 140. Therefore, its pressure is higher. Thus, the high pressure of the rebound flow in the oscillation chamber 150 is transmitted through the water passage section of the connecting section 140 (equivalent to a pressure relief process), thereby counteracting the negative pressure formed by the high-speed water flow at the outlet 1221. This causes the pressure in the intake section 130 to increase, and the pressure difference between the intake section and the external air source to decrease. As a result, the amount and velocity of the gas drawn in through the air hole 131 are reduced, which leads to a decrease in the velocity of the jet after the water and gas are mixed at the outlet 1221. Furthermore, the rebounding water flow, while releasing pressure, also introduces flow resistance to the subsequent jet entering from the connecting section 140. Consequently, the velocity and impact force of the water flow entering the mixing section 160 decrease. Therefore, the rebounding water flow formed in the mixing section 160 with reduced velocity and impact force is less than in the previous process, thus having less impact on the subsequent jet entering the connecting section 140. Consequently, the velocity and impact force of the jet entering the connecting section 140 increase again, thereby forming a pulsed jet with continuously changing velocity and impact force.

[0039] Based on this, when the user drives the regulating component 200 again, the water passage area of ​​the connecting section 140 will change. Taking the decrease in the water passage area of ​​the connecting section 140 as an example, when the water passage area of ​​the connecting section 140 decreases, the effect of transmitting the pressure of the rebound water flow to the outlet 1221 (i.e., the pressure relief effect of the oscillation section 150) becomes worse. At this time, the impact on the negative pressure of the outlet 1221 becomes smaller, so compared with the case when the regulating component 200 is not driven, the air intake section 130 draws in more gas. Therefore, the reduction in the flow velocity and impact force of the water flow is less than before, and thus the amplitude of the water flow pulse becomes smaller and the frequency becomes faster. Conversely, when the water passage area of ​​the connecting section 140 increases, the pressure relief effect of the oscillation section 150 becomes more obvious, corresponding to a greater impact on the negative pressure of the outlet 1221. Therefore, the reduction in the flow velocity and impact force is greater than before, and thus the amplitude of the water flow pulse becomes larger and the frequency becomes slower.

[0040] According to the specific embodiments of this utility model, the water outlet device can not only utilize the contraction section 120, air intake section 130, oscillation section 150, and mixing section 160 of the housing 100 and their bottom wall surface 162 to form pulse water outlet, but also allow the user to control the water passage area of ​​the connecting section 140 through the adjusting component 200, thereby controlling the weakening effect of the rebound water flow in the oscillation section 150 on the negative pressure of the water outlet 1221, and thus adjusting the amplitude and frequency of the pulse water outlet, thereby meeting the user's different water outlet rinsing needs and improving the user's cleaning experience.

[0041] It is understood that the "adjustment" mentioned in this utility model can be either the user manually controlling the movement of the adjusting component 200, or the adjusting component 200 being connected to a drive device such as a motor or hydraulic cylinder, allowing the user to control the drive device via buttons, remote control, or other terminal devices to control the adjusting component 200.

[0042] It is understandable that the air source can refer to air existing in the outside space, or it can be a gas cylinder or other equipment connected to the air intake 131.

[0043] refer to Figure 1 and Figure 4In some specific embodiments of this utility model, the housing 100 is provided with a mounting hole 141 communicating with the connecting section 140. At least a portion of the adjusting member 200 passes through the mounting hole 141 and is movably inserted into the connecting section 140. Specifically, at least a portion of the adjusting member 200 can reciprocate within the connecting section 140 to block part of the water-passing area of ​​the connecting section 140. For example, the adjusting member 200 can be rod-shaped, and the outer wall of the rod-shaped adjusting member 200 can be of various shapes, such as cylindrical or square column. The diameter and shape of the mounting hole 141 are adapted to the adjusting member 200 so that the adjusting member 200 can be inserted therein and at least a portion of the adjusting member 200 can be inserted into the connecting section 140 to change the water-passing area of ​​the connecting section 140.

[0044] refer to Figure 3 In some specific embodiments of this utility model, the inner wall of the mounting hole 141 is provided with an internal thread, and at least a portion of the outer peripheral wall of the adjusting member 200 is provided with an external thread. It can be understood that the internal space of the mounting hole 141 is cylindrical, and the portion of the adjusting member 200 passing through the mounting hole 141 is also cylindrical. Therefore, the user can rotate the adjusting member 200 to screw it into the mounting hole 141 and control the depth of screwing in to change the water passage area of ​​the connecting section 140, thus achieving stepless adjustment.

[0045] refer to Figure 4 and Figure 5 In some specific embodiments of this utility model, a plurality of first grooves 1411 are provided on the inner wall of the mounting hole 141. Specifically, the plurality of first grooves 1411 move in the same direction in the mounting hole 141 along the arrangement direction of the adjusting member 200. At least one second groove 211 is provided on the outer peripheral wall of the adjusting member 200. A pin 213 and a spring 212 are provided in the second groove 211. Specifically, one end of the spring 212 abuts against the bottom wall of the second groove 211, and the other end abuts against one end of the pin 213. Thus, the pin 213 can be moved... 3. The adjusting member 200 is retractably disposed in the second groove 211. In this embodiment, the adjusting member 200 can be pressed to slide in the mounting hole 141. The retractable pin 213 in the second groove 211 can cooperate with the first groove 1411 in the mounting hole 141. When the adjusting member 200 slides to the point where the pin 213 extends into a certain first groove 1411, it can achieve locking and positioning. The user can also continue to press or pull the adjusting member 200 to make the pin 213 enter another first groove 1411, thereby changing the water passage area of ​​the connecting section 140.

[0046] According to the specific embodiment of the present invention, the water outlet device can be positioned in a preset position by means of the first groove 1411, the second groove 211 and the retractable spring 212 and pin 213 therein, so that the pulse water outlet process of the water outlet device can be adjusted in a "gear-type" manner, which is convenient for users to control and adjust. In addition, the retractable spring 212 and pin 213 also provide users with a pressing or pulling feel during the adjustment process, resulting in a better user experience.

[0047] It is understandable that the number of first grooves 1411 at each preset adjustment position can be 2, 3 or other numbers. The first grooves 1411 at the same preset adjustment position are arranged circumferentially around the inner wall of the mounting hole 141. The number and position of the second grooves 211 on the adjustment member 200 are also set to correspond to the first grooves 1411 to achieve matching positioning.

[0048] It is understandable that other elastic elements and ball bearings or other components can be telescopically disposed in the second groove 211, as long as they can be inserted into the first groove 1411 and engaged.

[0049] refer to Figures 7-8 In some specific embodiments of this utility model, the adjusting member 200 includes a water baffle 230, wherein the water baffle 230 is disposed on the water inlet side or water outlet side of the connecting section 140 and can rotate in the housing, thereby changing the water passage area of ​​the connecting section 140 blocked by the water baffle 230.

[0050] refer to Figures 7-8 In some specific embodiments of this utility model, a water-passing hole 231 penetrating the disc body is provided on the water-baffle plate 230. In the water inlet direction, the water-passing hole 231 and the water-passing cross section of the connecting section 140 at least partially overlap. Furthermore, when the water-baffle plate 230 rotates, the overlapping area of ​​the water-passing hole 231 and the water-passing cross section of the connecting section 140 can be changed, thereby adjusting the water-passing area of ​​the connecting section 140.

[0051] refer to Figure 3In some specific embodiments of this utility model, the contraction section 120 includes a first constriction section 121 and a guide section 122. Specifically, the first constriction section 121 and the guide section 122 are connected sequentially along the water inlet flow direction. The water passage area of ​​the first constriction section 121 gradually decreases along the water inlet direction, while the water passage area of ​​the guide section 122 remains unchanged. That is, the end with the smallest water passage area of ​​the first constriction section 121 is connected to the guide section 122, and the water passage area of ​​the guide section 122 is the same as the smallest water passage area of ​​the first constriction section 121. The outlet end 1221 is set on the guide section 122, specifically on the end of the guide section 122 facing away from the first constriction section 121. Therefore, after entering the first constriction section 121, the water flow velocity gradually increases due to the gradually decreasing water passage area, and then enters the guide section 122. It is restricted and guided by the guide section 122 and can be sprayed out in alignment with the connecting section 140.

[0052] According to the specific embodiment of the present invention, the water outlet device guides the accelerated water flow through the guide section 122, which can ensure that the output direction of the water flow at the water outlet 1221 is aligned with the connecting section 140, so that it can enter accurately and avoid some water flow direction from deviating and entering the air intake section 130, affecting the air intake process of the air intake section 130 and affecting the air intake and jet effect.

[0053] In some specific embodiments of this utility model, the water outlet device is further provided with an inlet section 110, which is connected to one end of the first constriction section 121 opposite to the guide section, so that water can flow into the constriction section.

[0054] refer to Figure 3 In some specific embodiments of this utility model, the outer wall of the guide section 122 gradually narrows along the water inlet direction, that is, the guide section 122 is roughly conical in shape. This avoids the guide section 122 occupying too much space in the intake section 130, which would reduce the amount of gas drawn in and affect the jetting effect. Furthermore, the outer wall of the above-mentioned shape has a certain guiding effect on the gas entering from the intake hole 131, allowing the gas to be smoothly guided to the vicinity of the connecting section 140.

[0055] refer to Figure 3 In some specific embodiments of this utility model, the air intake section 130 includes an air intake section 132 and a second constriction section 133 connected sequentially along the water intake direction. The air intake hole 131 is disposed on the air intake section 132, and the air passage area of ​​the second constriction section 133 gradually decreases along the water intake direction.

[0056] By setting the second constriction section 133, the gas entering through the self-suction port 131 can be guided to a certain extent, so that the gas can be smoothly guided to the vicinity of the connecting section 140.

[0057] refer to Figure 2In some specific embodiments of this utility model, the adjusting member 200 is also provided with a driving part 220. For example, the adjusting member 200 may include a driving part 220 and a rod part 210 connected to each other. The driving part 220 may be a handle or driving end in the shape of a ball or a cover, so as to allow the user to drive it manually, or to connect it with a driving mechanism such as a motor, so as to realize the control and adjustment of the adjusting member 200.

[0058] It is understood that external threads or second grooves 211 are provided on the rod portion 210 of the adjusting member 200, and the end of the rod portion 210 facing away from the driving part 220 extends into the connecting section 140 to change its water passage area.

[0059] refer to Figures 7-8 In some specific embodiments of this utility model, the adjusting member 200 includes a driving part 220 and a water baffle plate 230. The user can manually or through a driving mechanism such as a motor control the driving part 220 to rotate, so that the water baffle plate 230 rotates around the driving part 220 as the axis, thereby adjusting the water passage area.
