As shown in fig. 11, it should be explained that the dashed box in the figure represents the projection of the oscillating water chamber 120 on a plane. The oscillating water chamber 120 includes two water outlets, and by means of a special chamber structure, the two water outlets can alternately discharge water, which is further developed in the following description. It should be noted that, in this embodiment, two water outlets of the oscillating water chamber 120 are all communicated with the shower water chamber 130, and the shower water chamber 130 is also communicated with the water outlet channel 151, so that when water flows through the oscillating water chamber 120, the shower water chamber 130 and the water outlet channel 151 to be sprayed out, oscillating shower water is formed, and a better massage effect is achieved.

It should be noted that, as shown in fig. 3, the water outlet device further includes a waterway switching assembly 200, and the waterway switching assembly 200 can alternatively communicate the water inlet channel 110 with the oscillating water chamber 120, the shower water chamber 130 and the granule water chamber 140. Thus, according to the difference of the communicating objects of the water inlet channel 110, the water outlet device of the embodiment of the application has the following three water outlet modes: the three water outlet modes are described one by one.

When the waterway switching assembly 200 communicates the water inlet channel 110 with the shower water cavity 130, as shown in fig. 5, 6 and 7, the water outlet device is in the shower water outlet mode, and water flows through the water inlet channel 110, the shower water cavity 130 and the water outlet channel 151 in sequence, so that columnar water type as shown in fig. 7 is formed, water bundles of the water type are concentrated, impact force is strong, and a good shower decontamination effect is achieved. As shown in fig. 8, 9 and 10, when the waterway switching assembly 200 communicates the water inlet channel 110 with the granule water cavity 140, the water outlet device is switched to the granule water outlet mode, and water flows through the water inlet channel 110, the granule water cavity 140 and the water outlet channel 151 in sequence, so as to form a divergent granular water type as shown in fig. 10, and the water beam of the water type is relatively dispersed, and is softer to the skin, and has better comfort. As shown in fig. 10 and 11 and referring to fig. 5, when the waterway switching assembly 200 communicates the water inlet channel 110 with the oscillating water cavity 120, the water outlet device is in the oscillating shower water outlet mode, and water flows sequentially through the water inlet channel 110, the oscillating water cavity 120, the shower water cavity 130 and the water outlet channel 151, so that intermittent columnar water type water as shown in fig. 12 is formed, and a better massage effect is achieved.

In the embodiment of the second aspect of the present application, as shown in fig. 13, the oscillating water cavity 120 is communicated with the particle water cavity 140, but the oscillating water cavity 120 in the embodiment of the first aspect is communicated with the shower water cavity 130, so that when the waterway switching assembly 200 communicates the water inlet channel 110 with the oscillating water cavity 120, the water outlet device in the embodiment of the second aspect is switched to the oscillating particle water outlet mode, and water flows sequentially through the water inlet channel 110, the oscillating water cavity 120, the particle water cavity 140 and the water outlet channel 151 and then is sprayed out, so that intermittent divergent water type is formed as shown in fig. 14, which is lighter than the oscillating shower water, but also has a better massaging effect.

Based on the above, the water outlet device of this application all goes out water through same kind of water outlet channel 151 under the play water mode of difference, and compare and need go out water through different water outlet channel 151 under the different play water modes among the prior art, the water outlet device of this application all has great play water range under the play water mode of difference to the water beam is comparatively concentrated. Moreover, the water type of the water outlet device in the vibration water outlet mode is kept consistent, the impact feeling of equal moment and interval is achieved, and a user can have better massage experience.

In a further embodiment of the first aspect of the present application, as shown in fig. 11, the oscillating water chamber 120 includes a first water outlet 123 and a second water outlet 124, the shower water chamber 130 is divided into a first subchamber 131 and a second subchamber 132, and it should be noted that the first subchamber 131 and the second subchamber 132 are not communicated with each other, and the first subchamber 131 and the second subchamber 132 are all communicated with a plurality of water outlet channels 151. The first water outlet 123 communicates with the first subchamber 131 and the second water outlet 124 communicates with the second subchamber 132. When the water inlet channel 110 is communicated with the oscillating water cavity 120, the first water outlet 123 and the second water outlet 124 can alternately discharge water, so that the water outlet channel 151 communicated with the first subchamber 131 and the second subchamber 132 alternately discharges water.

In a further embodiment of the second aspect of the present application, the particle water chamber 140 is divided into a third subchamber 141 and a fourth subchamber 142 which are not communicated with each other, the first water outlet 123 of the oscillating water chamber 120 is communicated with the third subchamber 141, and the second water outlet 124 is communicated with the fourth subchamber 142, so that the water outlet channels 151 communicated with the third subchamber 141 and the fourth subchamber 142 alternately outlet water.

In the prior art, the first water outlet 123 and the second water outlet 124 of the oscillation cavity are respectively connected with the particle water cavity 140 and the shower water cavity 130, so that the water outlet channels 151 communicated with the particle water cavity 140 and the shower water cavity 130 alternately discharge water. When the water outlet device is in the shower water outlet mode, water in the shower water cavity 130 may flow back to the particle water cavity 140 through the water outlet in the oscillation cavity, and then flows into the water outlet channel 151 through the particle water cavity 140 to form particle water, so that the situation of disordered water in the shower water outlet mode is caused, and when the water outlet device is in the particle water outlet mode, the water outlet effect may be affected by backflow in the same way.

In the above embodiment of the present application, since the first water outlet 123 and the second water outlet 124 of the oscillation cavity are respectively communicated with different subchambers of the same water cavity, for the water outlet device of the first embodiment, even if the first water outlet 123 and the second water outlet 124 are in backflow in the shower water outlet mode, the chambers before and after backflow are part of the shower water cavity 130, and still have the same water outlet type, so that the condition that the water type is disordered due to backflow cannot exist. With the water outlet device according to the embodiment of the second aspect, in the particulate water outlet mode, even if the backflow occurs at the first water outlet 123 and the second water outlet 124, the chambers before and after the backflow are part of the particulate water chamber 140, and the same water outlet type is still provided, so that the condition that the water type is disordered due to the backflow does not exist.

As shown in fig. 2 and 5, the water outlet assembly 100 further includes a second partition 160 and a third partition 170, and the third partition 170, the second partition 160 and the first partition 150 are disposed in parallel in the water outlet direction, that is, the third partition 170 and the first partition 150 are disposed at both sides of the second partition 160. The second partition 160 and the first partition 150 define the granule water chamber 140, and the third partition 170 and the second partition 160 define the shower water chamber 130. And, the second partition 160 is provided with water passing holes 162, and the shower nozzle 130 communicates with the water outlet passage 151 through the water passing holes 162.

Further, as shown in fig. 13 and 15, corresponding to the positions of the water outlet channels 151, a plurality of water passing protrusions 152 are disposed on the wall surface of the first partition 150 close to the second partition 160, wherein at least one water guiding channel 153 is disposed on the side wall of the water passing protrusion 152, the water guiding channel 153 is communicated with the granule water cavity 140 and the water outlet channels 151, and openings are disposed on the top of the water passing protrusion 152 and are communicated with the water passing holes 162 and the water outlet channels 151, so that the flow direction of the water flowing from the granule water cavity 140 to the water outlet channels 151 is not consistent with the flow direction of the water flowing from the shower water cavity 130 to the water outlet channels 151.

As shown in fig. 7, the cross section of the water outlet passage 151 is gradually reduced in the water outlet direction, that is, the water outlet passage 151 has a bell mouth structure at one end near the second partition 160. The water passing hole 162 is arranged corresponding to the water outlet channel 151, when water flows from the shower water cavity 130 to the water outlet channel 151 through the water passing hole 162, water flows vertically from top to bottom into the bell mouth of the water outlet channel 151, water flows out along the water outlet channel 151 with gradually reduced diameter, the impact resistance of the water flow is small, and the water flow can keep steady state, so that columnar water is formed.

For convenience of the following description, a junction of the water outlet channel 151, the water guide channel 153 and the water passing hole 162 is named as a junction chamber 154, and the junction chamber 154 is defined by the water passing protrusion 152. As shown in fig. 10, when water flows from the particle water chamber 140 to the water outlet channel 151 through the water guide channel 153, the water flowing in the horizontal direction first collides against the inner wall of the converging chamber 154, cuts each other to form turbulence, is pushed by the subsequent water flow to rotate along the inner wall of the converging chamber 154, and is sprayed out through the water outlet channel 151, and at this time, the water spray is in a divergent particle shape.

Further, as shown in fig. 15 and 16, in the embodiment of the present application, two water guide channels 153 are provided, and the two water guide channels 153 are tangential to the circumference of the water outlet channel 151, so that a vortex can be formed in the water outlet channel 151, and after being ejected from the water outlet channel 151, the water guide channels can have a horizontal velocity by inertia, so as to be divergent. The two water guide channels 153 are arranged in parallel, and it should be noted that the two water guide channels 153 are not coincident, so that no matter which water guide channel 153 the water flow enters into the converging cavity 154, the rotational speed of the vortex in the converging cavity 154 can be further improved, and the dispersing effect of the granular water spray is further enhanced.

Further, a plurality of abutment protrusions 161 are provided on a wall surface of the second partition 160 adjacent to the first partition 150 corresponding to the positions of the water passing protrusions 152, the abutment protrusions 161 are abutted against the water passing protrusions 152, and water passing holes 162 are provided through the abutment protrusions 161 to communicate the shower water chamber 130 with the water outlet passage 151. As shown in fig. 7, the abutment protrusion 161 defines a water passing chamber extending along the water outlet direction of the water passing hole 162, so that the water flow needs to pass through the water passing chamber when flowing to the water passing hole 162 in the shower water chamber 130, and the water passing chamber plays a guiding role of the water flow. If the water flowing through the water passing cavity is not guided, the water flowing direction in the water spraying cavity 130 is inconsistent with the water flowing direction of the water passing hole 162, which easily causes the water flowing through the water passing hole 162 to be disturbed, thereby influencing the water flowing type. In addition, as shown in fig. 15, the top of the water guide channel 153 of the water passing protrusion 152 is an open port, and this structure is relatively easy to process, and the abutment protrusion 161 can close the open port after abutting against the water passing protrusion 152.

In some embodiments, as shown in fig. 6, a partition 171 is protruded from either one of two opposite wall surfaces of the third partition 170 and the second partition 160, the partition 171 partitions a chamber between the third partition 170 and the second partition 160 into a first water distribution chamber 172, a second water distribution chamber 174 and a shower water chamber 130, wherein the first water distribution chamber 172 communicates with the oscillating water chamber 120, the second water distribution chamber communicates with the granule water chamber 140, the first water distribution chamber 172 includes a first water passage 173, the second water distribution chamber 174 includes a second water passage 175, the shower water chamber 130 includes a third water passage 133, and the waterway switching assembly 200 can alternatively communicate the water inlet channel 110 with the first water passage 173, the second water passage 175 and the third water passage 133 and close the remaining water passages.

As shown in fig. 3 and 4, the push button 210 is connected with a push rod 220, the push rod 220 is connected with a rack 230, the rack 230 is meshed with a gear 240, the gear 240 and the water diversion disk 250 can synchronously rotate, and a communication opening 251 is arranged on the water diversion disk 250. Accordingly, when the user pushes the button 210, the push rod 220 can be sequentially driven to move, so that the rack 230 drives the gear 240 to rotate, and the water distribution tray 250 rotates, so that the communication port 251 is selectively communicated with the first, second and third water communication ports 173, 175 and 133.

In order to realize the alternate water outlet of the first water outlet 123 and the second water outlet 124 of the oscillation cavity, as shown in fig. 4 and 17, two wedge-shaped flow guide blocks 121 are arranged in the oscillation cavity, a main flow channel 1211 is defined between the two wedge-shaped flow guide blocks 121, and a first feedback flow channel 1212 and a second feedback flow channel 1213 are respectively defined by the two wedge-shaped flow guide blocks 121 and the cavity wall of the oscillation water cavity 120. Specifically, the oscillating water chamber 120 further includes a first water inlet 125 that can be communicated with the water inlet channel 110, where the first water inlet 125 and the water outlet (including the first water outlet 123 and the second water outlet 124) are located at two sides of the oscillating water chamber 120, and water flow enters from the first water inlet 125 and is discharged from the first water outlet 123 or the second water outlet 124. After the water flow from the first water inlet 125 flows into the oscillating water chamber 120, a pressurized jet is first formed through the necked down orifice 126. The main flow channel 1211 alternately directs the flow of water to the first water outlet 123 and the second water outlet 124 by a pressure differential between the first feedback flow channel 1212 and the second feedback flow channel 1213.

The main flow channel 1211 is configured to receive the pressurized jet of the first water inlet 125 to alternately flow to the first feedback flow channel 1212 and the second feedback flow channel 1213, and one ends of the first feedback flow channel 1212 and the second feedback flow channel 1213 are located at two sides of the neck opening 126. The interval between both sides of the main flow channel 1211 gradually increases in the water flow direction. When fluid enters the main flow channel 1211 from the necking port 126, the flow state of the fluid is laminar and turbulent, the critical state of the fluid is determined by the Reynolds number Re, re=du/V, where u is the average flow velocity m/s of the jet outlet, d is the characteristic length of the jet outlet, and is generally represented by the diameter corresponding to the equivalent cross-sectional area circle, and V is the kinematic viscosity coefficient, theoretically, the jet Re is approximately 2000, and the jet Re ejected from the narrow and long slit or orifice is generally >30, thus forming the jet in turbulent state. When the fluid is in a flocculation state, due to the coanda effect of the fluid, the fluid tends to flow along one side of the main channel 1211 in the drawing, and the other side of the main channel 1211 is sucked, so that the water on the other side is brought into the flowing side, and a pressure difference is generated between the two sides P1 and P2 of the first feedback channel and the second feedback channel. The initial side of the state of flocculation is random. Assuming that the initial water flows down along the left side of the main channel 1211, the water on the right side of the main channel 1211 is sucked up to the left side (the water is discharged from the first water outlet 123 on the left side at this time) by the entrainment effect, so that P1> P2 in the first feedback channel and the second feedback channel is caused, when P1 is greater than P2, the fluid flows to the negative pressure side due to the pressure difference on both sides of the neck down 126, that is, the fluid starts to flow down to the right side of the main channel 1211 (the water is discharged from the second water outlet 124 on the right side at this time), and the water on the left side of the main channel 1211 is sucked up to the right side of the main channel 1211 due to the entrainment effect, so that P1< P2 in the first feedback channel and the second feedback channel is caused. When P1< P2, the fluid flows to the negative pressure side due to the pressure difference at the two sides of the neck down 126, i.e. starts to flow down to the left side of the main flow channel 1211 (the water is discharged from the first water outlet 123 at the left side at this time), thus completing a left-right oscillation cycle.

In the embodiment shown in fig. 18, several other embodiments of the oscillating water chamber 120 are also proposed, and the above-mentioned effect of oscillating water can be achieved.

In other embodiments, as shown in fig. 19, a concave diversion block 122 is disposed in the oscillating water chamber 120, the opening of the concave diversion block 122 is disposed towards the first water inlet 125, the inner side of the concave diversion block 122 forms a backwater chamber 1221, and the outer side is respectively connected with the wall of the oscillating water chamber 120 to eject a first flow passage 1222 communicating with the first water outlet 123 and a second flow passage 1223 communicating with the second water outlet 124. Wherein the return water chamber 1221 directs the flow of water alternately to the first 1222 and second 1223 channels by a pressure differential at the inlet of the return water chamber 1221.

The return water chamber 1221 alternately guides the jet flow entering therein to the first and second passages 1222 and 1223, the first and second passages 1222 and 1223 being symmetrically disposed on the left and right sides of the return water chamber 1221, and when the water flow enters the return flow passage from the necked-down port 126, a coanda effect occurs and causes the pressure and velocity of the inlets of the first and second passages 1222 and 1223 to be different. When the pressure P1 at the inlet of the first flow path 1222 is smaller than the pressure P2 at the inlet of the second flow path 1223, the water flow is guided to one side of the first flow path 1222, so that the water flow from the necking port 126 enters the left side of the water return chamber 1221, is guided to the inlet of the second flow path 1223 through the left side wall of the water return chamber 1221, and is output from the second flow path 1223 to the second water outlet 124; when the velocity of the inlet of the second flow passage 1223 reaches a certain value, the velocity of the inlet of the second flow passage 1223 is greater than the velocity of the inlet of the first flow passage 1222, resulting in the pressure P1 of the inlet of the first flow passage 1222 being greater than the pressure P2 of the inlet of the second flow passage 1223, the fluid is guided to one side of the second reverse flow passage due to the pressure difference, so that the fluid from the necking port 126 enters the right side of the backwater chamber 1221, is guided to the inlet of the first flow passage 1222 through the right side wall of the backwater chamber 1221, and is outputted from the first flow passage 1222 to the first water outlet 123.
