Description

Technical Field

[0001] The invention relates to the field of bathroom equipment, in particular to a water outlet device. Background Art

[0002] At present, some shower products are equipped with an air suction mechanism, so that the water flow in the shower sucks in the outside air and mixes it to form bubble water, so as to achieve a soft water discharge effect. However, in the prior art, the air suction mechanism such as the air suction hole of the above-mentioned air suction shower is usually set on the shower head, or even on the shower handle. Once the above setting is completed, the bubble water function of the shower product cannot be changed. The same type of water outlet can only output bubble water alone, or a separate non-bubble water channel and outlet need to be set up separately, which is not conducive to the simplification of the shower structure and cannot meet the diverse shower needs of users. Summary of the invention

[0003] The present invention provides a water outlet device, aiming to solve the technical problem that the bubble water outlet function of the air suction shower in the prior art is fixed and cannot be changed, and cannot meet the diverse showering needs of users.

[0004] To achieve the above object, a first aspect of the present invention provides a water outlet device, comprising: a housing, wherein the housing comprises a water inlet hole, a water passage cavity and a water outlet hole connected in sequence; a water outlet component, movably arranged in the water hole, wherein a first water channel and a second water channel are sequentially arranged in the water outlet component along the water flow direction, the water flow cross-sectional area of ​​the first water channel gradually decreases along the water flow direction, and at the connection point between the second water channel and the first water channel, the water flow cross-sectional area of ​​the second water channel is greater than the water flow cross-sectional area of ​​the first water channel, and a first air hole is further arranged on the peripheral wall of the water outlet component; A driving assembly is rotatably disposed in the water passage chamber, and the driving assembly provides a force to the water outlet assembly to drive the water outlet assembly to move relative to the water outlet hole, wherein during the movement of the water outlet assembly, the first air hole is connected to the outside or is closed by the inner wall of the water outlet hole.

[0005] According to the water outlet device provided by the embodiment of the first aspect of the present invention, the driving component is rotatably arranged in the water passage cavity and provides a force to the water outlet component to drive the water outlet component to move relative to the water outlet hole. During the movement of the water outlet component, the first air hole will continuously switch between the two states of being connected and being closed by the inner wall of the water outlet hole. When the first air hole is closed by the inner wall of the water outlet hole, no gas enters the second water channel, so the water outlet component outputs ordinary shower water. When the first air hole is connected, the water outlet component outputs bubble water, and the water flow is softer at this time, and the impact force on the human body is less than that of ordinary shower water. With the switching of the opening and closing state of the first air hole, the water outlet of the water outlet component switches between the two water outlet states of shower water and bubble water, making the skin feel more diverse during showering and meeting the different showering needs of users. At the same time, it also avoids the problem that in some air-inhaling showers in the prior art, the same type of water outlet components can only fix the bubble water outlet and cannot be changed. The present invention does not need to separately set the waterway and water outlet of non-bubble water. The shower water and bubble water can be circulated and output through a single water outlet component, which is conducive to the simplification and miniaturization design of the shower structure.

DETAILED DESCRIPTION

[0022] 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.

[0023] refer to Figure 1 and Figure 2In some specific embodiments of the present invention, a water outlet device 1000 is provided, which can be applied to the field of bathroom shower or kitchen water use. For example, the water outlet device 1000 can be used as a component of a shower head 2000, and is arranged in a housing 2100 of the shower head 2000, and is connected to a water inlet channel 2110 of the housing 2100. When water flows through the water outlet device 1000, the water outlet component 200 can inhale gas to form bubble water, and through the driving component 300 therein, the water outlet component 200 can be driven to move and switch the water outlet component 200 between the air inhalation-non-air inhalation state, thereby changing the bubble water outlet state of the shower head to meet the user's diverse shower needs.

[0024] refer to Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 8 The water outlet device 1000 provided in the embodiment of the present invention includes a housing 100 , a water outlet assembly 200 and a driving assembly 300 .

[0025] The shell 100 includes a water inlet hole 111, a water passage cavity 130 and a water outlet hole 121 which are connected in sequence. Specifically, the shell 100 can be composed of an upper shell 110 and a lower shell 120. The water inlet hole 111 is arranged in the upper shell 110, and the water outlet hole 121 is arranged in the lower shell 120. The upper shell 110 and the lower shell 120 enclose the water passage cavity 130.

[0026] The water outlet assembly 200 is movably disposed in the water outlet hole 121. The water outlet assembly 200 is sequentially provided with a first water channel 210 and a second water channel 220 that are interconnected. Through the first water channel 210 and the second water channel 220, the water outlet assembly 200 is connected to the water cavity 130 and the outside world. Water can enter the water cavity 130 through the water inlet hole 111, and flow out after passing through the first water channel 210 and the second water channel 220 of the water outlet assembly 200. Among them, the water flow cross-sectional area of ​​the first water channel 210 gradually decreases along the water flow direction. At the connection between the second water channel 220 and the first water channel 210, the water flow cross-sectional area of ​​the second water channel 220 is greater than the water flow cross-sectional area of ​​the first water channel 210. The peripheral wall of the water outlet assembly 200 is also provided with a first air hole 221 that connects the second water channel 220 and the outside world. Therefore, due to the Venturi principle, when water flows from the first water channel 210 with a gradually decreasing water flow cross-sectional area into the second water channel 220 with a larger water flow cross-sectional area, a negative pressure is formed on one side of the second water channel 220 at the connecting point, and the pressure is less than the atmospheric pressure. At this time, the outside gas will enter the second water channel 220 through the first air hole 221 and mix with the water flow to form bubble water.

[0027] The driving assembly 300 is rotatably disposed in the water passage chamber 130 and provides a force to the water outlet assembly 200 to drive the water outlet assembly 200 to move relative to the water outlet hole 121. During the movement of the water outlet assembly 200, the shape of the water outlet will also shrink ( Figure 3 ) and diffusion ( Figure 4 ) and the first air hole 221 will continuously switch between the two states of being connected to the outside and being closed by the inner wall of the water outlet hole 121. When the first air hole 221 is closed by the inner wall of the water outlet hole 121 ( Figure 4 ), no gas enters the second water channel 220, so the water outlet assembly 200 outputs ordinary shower water. When the first air hole 221 is opened ( Figure 3 ), the water outlet component 200 outputs bubble water, at this time the water flow is softer, and the impact force on the human body is less than that of ordinary shower water. As the opening and closing states of the first air hole 221 are switched, the water outlet of the water outlet component 200 switches between the two water outlet states of shower water and bubble water, making the skin feel during showering more diverse and meeting the different showering needs of users. At the same time, it also avoids the problem that in some air-inhaling showers in the prior art, similar water outlet components 200 can only fix the bubble water outlet and cannot be changed. The present invention does not need to set up a waterway and outlet for non-bubble water separately. Shower water and bubble water can be circulated and output through a single water outlet component 200, which is conducive to the simplification and miniaturization of the shower structure.

[0028] It is understandable that the drive component can be in various forms. For example, it can be set as an electric drive component, which drives the water outlet component 200 to move when powered on, or it can be set as a hydraulic drive component, and water flow enters to move the drive component 300, thereby driving the water outlet component 200 to move.

[0029] refer to Figure 6 , Figure 7 and Figure 8 In some embodiments of the present invention, the water outlet assembly 200 includes a water outlet, a rotating shaft 240 is arranged on the outer wall of the water outlet, and a shaft groove 122 is arranged on the water outlet hole 121 for the rotating shaft 240 to be placed therein. Through the cooperation between the rotating shaft 240 and the shaft groove 122, the water outlet can swing around the rotating shaft 240 in the water outlet. Therefore, when the driving assembly 300 swings the water outlet, when the first air hole 221 swings to a position that fits with the inner wall of the water outlet hole 121, the first air hole 221 is closed, and when the first air hole 221 leaves the fitting position, the first air hole 221 is opened.

[0030] refer to Figure 5 and Figure 8In some embodiments of the present invention, a plurality of water outlet holes 121 are provided on the water outlet device, and the plurality of water outlet holes 121 can be arranged in sequence along a circular trajectory, and a water outlet component 200 is movably provided in each water outlet hole 121. A first magnetic component 230 is also provided on the water outlet component 200, and a plurality of second magnetic components 330 are correspondingly provided on the driving component 300, that is, the plurality of second magnetic components 330 can rotate with the rotation of the driving component 300, and the second magnetic components 330 can also be arranged in sequence along a circular trajectory. Specifically, a circular ring composed of the plurality of second magnetic components 330 is located in the circular ring composed of the first magnetic component 230, and the two circular rings are on the same horizontal plane, thereby realizing a relative arrangement between the first magnetic component 230 and the second magnetic component 330. Among them, the surfaces relative to at least one first magnetic component 230 and at least one second magnetic component 330 have opposite magnetism, and the surfaces relative to at least one first magnetic component 230 and at least one second magnetic component 330 have the same magnetism. During the rotation of the second magnetic component 330 with the driving component 300, when the two surfaces with opposite magnetism are positioned relative to each other, the first magnetic component 230 is attracted to and deviates toward the second magnetic component 330, and the water outlet 250 of the water outlet component 200 is deviated in a direction away from the second magnetic component 330. When the two surfaces with the same magnetism are positioned relative to each other, the first magnetic component 230 is repelled and deviates in a direction away from the second magnetic component 330, while the water outlet 250 of the water outlet component 200 is deviated in a direction close to the second magnetic component 330. Taking the case where the first air hole 221 is arranged on the side of the water outlet component 200 facing away from the second magnetic component 330 as an example, when the water outlet 250 of the water outlet component 200 deviates in a direction away from the second magnetic component 330, the first air hole 221 is blocked and closed by the inner wall of the water outlet hole 121, and no gas enters at this time, and the water outlet 250 outputs ordinary shower water without mixed gas. When the water outlet 250 of the water outlet component 200 deviates in a direction close to the second magnetic component 330, the first air hole 221 and the inner wall of the water outlet hole 121 are away from each other, and the first air hole 221 is connected. At this time, the gas enters the second water channel 220 through the first air hole 221 and mixes with the water flow, and the water outlet 250 outputs bubble water.

[0031] In this embodiment, the first magnetic part 230 and the second magnetic part 330 can be set to drive the water outlet component 200 to swing, so as to control the first air hole 221 to continuously switch between the conductive state and the closed state as the water outlet component 200 swings, thereby continuously and automatically providing the user with a diverse shower experience.

[0032] It is understandable that the first air hole 221 can also be arranged on the side of the water outlet component 200 close to the second magnetic component 330. At this time, the principle is the same as the above embodiment. When the magnetism is the same, the first air hole 221 is closed and no air enters. When the magnetism is opposite, the first air hole 221 is open to air intake. The specific process will not be repeated here.

[0033] It is particularly pointed out here that in the contents of the subsequent embodiments, unless otherwise specified, the first air hole 221 is arranged on the side of the water outlet component 200 away from the second magnetic component 330 for explanation, but it should be understood that the above examples are only for the purpose of uniformly and clearly explaining the technical solutions of the embodiments, and do not mean that the first air hole 221 can only be arranged on one side.

[0034] In addition, in the subsequent embodiments, in order to explain the technical solutions of the embodiments more clearly and briefly, some drawings only show different arrangement diagrams of the first magnetic member 230 and the second magnetic member 330 .

[0035] In some embodiments of the present invention, the magnetic pole directions of the first magnetic members 230 and the second magnetic members 330 may be arranged in different ways, so that the water output of the water output device 1000 is more diversified: For example, a plurality of first magnetic members 230 are arranged in sequence along a circular trajectory at intervals. On any two adjacent first magnetic members 230, the magnetism of the side close to the second magnetic member 330 is opposite. At this time, no matter what the magnetism of the end of the second magnetic member 330 close to the first magnetic member 230 is, as long as the second magnetic member 330 rotates with the driving component 300, it will always be opposite to the first magnetic member 230 with the same magnetism and the first magnetic member 230 with opposite magnetism in turn during the rotation process. At this time, the water outlet component 200 is driven to swing back and forth in turn to form different water outlet shapes, and different first air holes 221 are continuously opened and closed, that is, the water outlets 250 with different swinging directions will output bubble water and shower water respectively.

[0036] For another example, a plurality of second magnetic members 330 are arranged in sequence along a circular trajectory at intervals. On any two adjacent second magnetic members 330, the magnetism of the side close to the first magnetic member 230 is opposite. At this time, no matter what the magnetism of the end of the first magnetic member 230 close to the second magnetic member 330 is, as long as the second magnetic member 330 rotates with the driving component 300, it will always be opposite to the first magnetic member 230 with the same magnetism and the first magnetic member 230 with opposite magnetism in turn during the rotation process. At this time, the water outlet component 200 is driven to swing back and forth in turn to form different water outlet shapes, and different first air holes 221 are continuously opened and closed, that is, the water outlets 250 with different swinging directions will output bubble water and shower water respectively.

[0037] refer to Fig. 9Alternatively, a plurality of first magnetic members 230 may be arranged in sequence along a circular track at intervals, and on any two adjacent first magnetic members 230, the magnetism of the side close to the second magnetic member 330 is opposite. At the same time, a plurality of second magnetic members 330 may be arranged in sequence along a circular track at intervals, and on any two adjacent second magnetic members 330, the magnetism of the side close to the first magnetic member 230 is opposite. In the process of the second magnetic members 330 rotating with the driving assembly 300, when the magnetism of the side opposite to the first magnetic member 230 of each second magnetic member 330 and the first magnetic member 230 opposite to it is the same, the first magnetic members 230 are pushed by the repulsive force, so that the water outlet 250 of the water outlet assembly 200 swings toward the direction close to the second magnetic member 330, that is, the water outlet direction of the water outlet assembly 200 is contracted toward the direction of the rotation axis L of the driving assembly 300. At this time, all the first air holes 221 are connected, and the water outlet is bubble water. When the second magnetic member rotates until the magnetism of the opposite surface of each second magnetic member 330 and the opposite first magnetic member 230 is opposite, the first magnetic members 230 are attracted by the magnetic attraction force, so that the water outlet 250 of the water outlet component 200 swings in the direction away from the second magnetic member 330, that is, the water outlet direction of the water outlet component 200 spreads in the direction away from the rotation axis L of the driving component 300. At this time, all the first air holes 221 are closed, and the outlet water is ordinary shower water.

[0038] According to the above embodiment, as the driving component 300 rotates, the multiple second magnetic parts 330 also rotate accordingly. Therefore, the magnetism of each second magnetic part 330 relative to the first magnetic part 230 also changes all the time. During this change, the multiple water outlet components 200 continuously swing back and forth, and the shape of the water outlet switches between the contraction and diffusion states. In the process of switching the state of the water outlet shape, the water outlet type also continuously switches between bubble water and shower water, providing users with a dynamic and diverse water outlet effect and shower experience.

[0039] refer to Fig.10 In some embodiments of the present invention, a plurality of first magnetic members 230 are arranged in sequence along a circular trajectory. On any two adjacent first magnetic members 230, the magnetism of the side close to the second magnetic member 330 is opposite, and the magnetism of the sides of all second magnetic members 330 close to the first magnetic member 230 is the same.

[0040] In this embodiment, the second magnetic member 330 rotates with the rotation of the driving assembly 300. During the rotation process, one of the two adjacent first magnetic members 230 is always repelled by the second magnetic member 330 with the same magnetism, so that the water outlet 250 swings toward the direction close to the second magnetic member 330, and the other is attracted by the second magnetic member 330 with opposite magnetism, so that the water outlet 250 swings toward the direction away from the second magnetic member 330, and the swinging direction is continuously repeated. Therefore, the water outlet device 1000 has a water outlet shape that shrinks and moves closer to the second magnetic member 330 and a water outlet shape that spreads away from the second magnetic member 330 at the same time, and the two water outlet shapes are cyclically converted with each other to achieve the diversification of water outlet shapes and make them more beautiful. At the same time, since the first air hole 221 is arranged on the side of the water outlet component 200 facing away from the second magnetic component 330, the water outlet of the contraction water type is bubble water, and the water outlet of the diffusion water type is shower water, and the two water outlet types can be continuously switched with the cyclic conversion of the water outlet shape, providing users with a dynamic and diverse water outlet effect and shower experience.

[0041] Understandably, reference Fig.11 Alternatively, a plurality of second magnetic members 330 may be arranged in sequence along a circular trajectory at intervals. On any two adjacent second magnetic members 330, the magnetism of the side close to the first magnetic member 230 is opposite, and the magnetism of the sides of all first magnetic members 230 close to the second magnetic member 330 is the same. In this example, the working distance, process and water discharge effect of the water outlet device 1000 are the same as those in the above embodiment and will not be repeated here.

[0042] refer to Fig.12 In some embodiments of the present invention, the shape and type of water discharge can be further changed by designing the driving assembly 300. The driving assembly 300 may further include a push member, and the maximum distance between the outer wall of the push member and the rotation axis L of the driving assembly 300 is S1. When the first magnetic member 230 is offset toward the second magnetic member 330 by the magnetic attraction force, the minimum distance between the outer wall of the first magnetic member 230 and the rotation axis L of the driving assembly 300 is S2, wherein S1>S2.

[0043] Therefore, when the push-pull member rotates with the driving assembly 300, it pushes against the first magnetic member 230 on the water outlet assembly 200 that is offset by the magnetic attraction force, so that the pushed first magnetic member 230 moves in a direction away from the second magnetic member 330. At this time, the water outlet direction of the water outlet assembly 200 affected by the push-pull member also gradually shrinks, so that the water outlet device 1000 has a third water outlet shape between the diffuse water type and the contraction water type in addition to the diffuse water type and the contraction water type, and the first air hole 221 is also turned on at this time, and the water outlet of the third water type is shower water. Therefore, the water outlet shapes and types of the water outlet device 1000 are further enriched.

[0044] It is understandable that when the first magnetic member 230 is not affected by the suction or repulsion and is deflected, the minimum distance between the outer peripheral wall of the first magnetic member 230 and the rotation axis L of the driving assembly 300 may be less than or equal to S1. When the minimum distance is equal to S1, the first magnetic member 230 is pushed by the push member and just resets to the position when it is not deflected. When the minimum distance is less than S1, the first magnetic member 230 is pushed and gradually resets from the diffuse water type, and after passing the position when it is not deflected, it gradually changes to the contraction water type.

[0045] It is understandable that the push member can be a push block provided on the driving assembly 300, which can push against the first magnetic member 230 when it rotates with the driving assembly 300. It can also be an annular rib, annular convex block, etc., which is not limited here.

[0046] refer to Fig.12 and Fig.18 In some embodiments of the present invention, the push-pull member is an annular receiving groove 321, and the receiving groove 321 is arranged on the side of the driving assembly 300 close to the water outlet assembly 200, and each second magnetic member 330 is received in the receiving groove 321 to achieve positioning. The maximum distance between the outer peripheral wall of the receiving groove 321 and the rotation axis L of the driving assembly 300 is S1, and the minimum distance is S3, wherein S1>S2>S3. Therefore, when the push-pull member rotates with the driving assembly 300, it will push the first magnetic member 230 on the water outlet assembly 200 that is offset by the magnetic attraction force, so that the pushed first magnetic member 230 moves in a direction away from the second magnetic member 330. At this time, the water outlet direction of the water outlet assembly 200 affected by the push-pull member is also gradually contracted, so that the water outlet device 1000 has a third water outlet shape between the diffuse water type and the contracted water type in addition to the diffuse water type and the contracted water type, and the first air hole 221 is also turned on at this time, and the water outlet of the third water type is shower water. Therefore, the shapes and types of water outlets of the water outlet device 1000 are further enriched.

[0047] It is understandable that, in this embodiment, when the first magnetic member 230 is not offset by the attraction or repulsion, the minimum distance between the outer peripheral wall of the first magnetic member 230 and the rotation axis L of the driving assembly 300 is greater than S3.

[0048] It is understandable that the push member or the receiving groove 321 may be circular in shape and eccentrically arranged relative to the rotation axis L of the driving assembly 300. It may also be an elliptical ring shape or other irregular ring shape. In this case, the push member or the receiving groove 321 may not be eccentrically arranged, and the distances between different positions of its outer peripheral wall and the rotation axis L of the driving assembly 300 are also different, and the technical effects of the above-mentioned embodiment can also be achieved.

[0049] In some embodiments of the present invention, a plurality of second magnetic members 330 are sequentially connected to form an annular push member, and the minimum distance between the outer peripheral wall of the push member and the rotation axis L of the driving assembly 300 is S3, wherein S2>S3.

[0050] refer to Fig.13 and Fig.14 In this embodiment, the second magnetic member 330 can be directly fixed to the driving component 300 by bonding or the like, and the annular push member composed of multiple second magnetic members 330 directly contacts the first magnetic member 230. There is no need to add an additional push structure to the driving component 300, which is conducive to further simplifying the structural design and saving the internal volume of the water outlet device 1000, which is conducive to the miniaturization and compact design of the water outlet device 1000.

[0051] refer to Fig.12 and Fig.15 In some embodiments of the present invention, a plurality of first magnetic members 230 are arranged in sequence along a circular trajectory at intervals, and the magnetism of the side close to the second magnetic member 330 is the same, and a plurality of second magnetic members 330 are arranged in sequence along a circular trajectory at intervals, and the magnetism of the side close to the first magnetic member 230 is the same, wherein the magnetism of the opposite surfaces between all first magnetic members 230 and all second magnetic members 330 is opposite. The driving assembly 300 also includes a push member, and the maximum distance between the outer peripheral wall of the push member and the rotation axis L of the driving assembly 300 is S1. When the first magnetic member is offset toward the second magnetic member 330 by the magnetic attraction of the first magnetic member 230, the minimum distance between the outer peripheral wall of the first magnetic member 230 and the rotation axis L of the driving assembly 300 is S2, wherein S1>S2.

[0052] In this embodiment, since the magnetism of the opposing surfaces of all the first magnetic members 230 and all the second magnetic members 330 is opposite, during the rotation of the driving assembly 300, the first magnetic members 230 are always offset by the magnetic attraction of the second magnetic members 330. Therefore, the water outlet direction of the water outlet 250 always forms a diffuse shape, and the first air hole 221 is blocked, and the water outlet device 1000 always outputs ordinary shower water in a diffuse shape. On this basis, since the maximum distance between the outer wall of the pushing member and the rotation axis L of the driving component 300 is greater than the minimum distance between the outer wall of the first magnetic component 230 and the rotation axis L of the driving component 300 when the pushing member is offset by the magnetic attraction force, the pushing member will always push the first magnetic component 230 that meets it during the rotation of the driving component 300 to cause it to offset in the direction away from the second magnetic component 330. At this time, the water outlet direction of the pushed water outlet component 200 gradually shrinks. At this time, the first air hole 221 is connected, so this part of the water outlet component 200 outputs bubble water in a contracted shape. As the driving component 300 rotates, the water outlet component 200 that is contracting and discharging water continuously changes, forming a dynamically changing water outlet shape.

[0053] It is understandable that the shape of the push member can be designed in a variety of ways, such as the push member can be set to have only one protrusion, and the protrusion can only push one first magnetic member 230 to move. It can also be set with multiple protrusions, or be elliptical or eccentric circle shape, so that it can always push multiple first magnetic members 230 to move at the same time during the rotation process, thereby forming different dynamic change effects.

[0054] refer to Fig.12 and Fig.18 In some embodiments of the present invention, the push-pull member is an annular receiving groove 321, and the receiving groove 321 is arranged on the side of the driving assembly 300 close to the water outlet assembly 200, and each second magnetic member 330 is received in the receiving groove 321 to achieve positioning. The maximum distance between the outer peripheral wall of the receiving groove 321 and the rotation axis L of the driving assembly 300 is S1, and the minimum distance is S3, wherein S1>S2>S3. Therefore, when the push-pull member rotates with the driving assembly 300, it will push against the first magnetic member 230 on the water outlet assembly 200 that is displaced by the magnetic attraction force, so that the pushed first magnetic member 230 moves in a direction away from the second magnetic member 330. At this time, the water outlet direction of the water outlet assembly 200 affected by the push-pull member also gradually shrinks.

[0055] It is understandable that, in this embodiment, when the first magnetic member 230 is not offset by the attraction or repulsion, the minimum distance between the outer peripheral wall of the first magnetic member 230 and the rotation axis L of the driving assembly 300 is greater than S3.

[0056] It is understandable that the push member or the receiving groove 321 may be circular in shape and eccentrically arranged relative to the rotation axis L of the driving assembly 300. It may also be an elliptical ring shape or other irregular ring shape. In this case, the push member or the receiving groove 321 may not be eccentrically arranged, and the distances between different positions of its outer peripheral wall and the rotation axis L of the driving assembly 300 are also different, and the technical effects of the above-mentioned embodiment can also be achieved.

[0057] refer to Fig.13 , Fig.14 and Fig.16 In some embodiments of the present invention, a plurality of second magnetic members 330 are sequentially connected to form an annular push member, and the minimum distance between the outer peripheral wall of the push member and the rotation axis L of the driving assembly 300 is S3, wherein S2>S3.

[0058] In this embodiment, the second magnetic component 330 can be directly fixed to the driving component 300 by bonding or the like, and the annular push-resistance component composed of multiple second magnetic components 330 is directly in contact with the first magnetic component 230. There is no need to add an additional push-resistance structure to the driving component 300, which is conducive to further simplification of the structural design and saving of the internal volume of the water outlet device 1000, which is conducive to the miniaturization and compact design of the water outlet device 1000.

[0059] refer to Fig.17 In some embodiments of the present invention, a second air hole 222 connecting the inside of the second water channel 220 and the outside is further provided on the peripheral wall of the water outlet component 200, and the first air hole 221 and the second air hole 222 are symmetrical with respect to the axis of the water outlet component 200.

[0060] In this embodiment, no matter whether the first magnetic member 230 is attracted or repelled by the second magnetic member 330, one pore is always connected and the other pore is blocked, that is, no matter whether the water output is diffused water type or contracted water type, the water output type is always bubbles, but when any pore is blocked, only one pore inhales gas. When the first magnetic member 230 is swinging, there is a situation where the first pore 221 and the second pore 222 are connected at the same time. For example, when the first magnetic member 230 is pushed by the push member to reset to a position where no displacement occurs, the two pores are connected to intake air at the same time. At this time, the intake volume is larger, more gas is mixed in the bubble water, and the shower skin feels softer.

[0061] It is understandable that the two air holes will not be limited to the time when the first magnetic part 230 is in a non-shifted position to allow air to enter at the same time. In fact, as long as one side of the water outlet component 200 is out of contact with the inner wall of the water outlet hole 121 and the other side has not yet contacted the inner wall of the water outlet hole 121, the two air holes will be opened at the same time. During this whole process, more mixed gas and softer bubble water will be output.

[0062] refer to Figure 3 and Figure 5 In some embodiments of the present invention, the driving assembly 300 includes an impeller assembly 310, a turntable 320 is disposed on the impeller assembly 310, a thrust member is disposed on a side of the turntable 320 close to the water outlet assembly 200, and a second magnetic member 330 is disposed on a side of the turntable 320 close to the water outlet assembly 200.

[0063] It can be understood that the impeller assembly 310 and the turntable 320 can be directly connected or connected through the transmission rod 340, or the impeller assembly 310 and the turntable 320 can be designed as an integral part, or the impeller assembly 310 and the turntable 320 can be driven and connected by some existing technologies such as reduction gears and reduction plates. In short, as long as the impeller assembly 310 rotates, the turntable 320 can rotate synchronously, and there is no limitation here.

[0064] In this embodiment, after water flows in from the water inlet 111, it impacts the impeller assembly 310 to rotate, and the impeller assembly 310 drives the rotating disk 320 to rotate. At this time, the second magnetic member 330 rotates accordingly, and drives the first magnetic member 230 to swing. At the same time, the push member also rotates, and pushes the first magnetic member 230 that meets it to deviate, providing users with more diverse water outlet shapes.
