When the connecting part 120 is connected to the fixing member 200 by the way of the protrusion 122 and the engaging groove 210, the introducing tube 300 is located at the first position, and meanwhile, the introducing tube 300 is also subjected to the force of the second elastic element 410, so that the introducing tube 300 tends to move to the second position, and the introducing tube 300 is located at the first position due to the pressing of the connecting part 120, and finally, the water flow can sequentially flow through the introducing channel 310, the inside of the container 100, and the guiding channel 320, so that the essential oil can be flushed out by the water flow.

In addition, as can be seen, the direction of the water flow through the inlet channel 310 is opposite to the direction of the water flow through the outlet channel 320, and the opposite direction of the water flow can flush the essential oil from the container 100.

As shown in fig. 3 and 12, fig. 12 is a partially enlarged view at K in fig. 4. The valve core 500 according to the embodiment of the present invention is disposed in the water distributing body 400, the valve core 500 can move between the third position and the fourth position, and when the valve core 500 is located at the third position, the first water flow passage 2100 and the introduction passage 310 can be blocked, and when the valve core 500 is located at the fourth position, the first water flow passage 2100 and the introduction passage 310 are communicated.

The switching assembly 700 comprises a push button 710 and a push plate 720, wherein the push plate 720 comprises a clamping portion 723, a first recess 721 and a second recess 722, and the clamping portion 723 can be clamped in the clamping groove 510 of the valve core 500. The push button 710 is coupled to the push plate 720, and when the user pushes the push button 710, the push plate 720 can move the valve cartridge 500 between the third position and the fourth position.

The water outlet device further comprises a positioning assembly 800, and the positioning assembly 800 can selectively position the valve core 500 at a third position or a fourth position. The positioning assembly 800 includes a first elastic element 820 and a positioning pin 810, and one end of the first elastic element 820 abuts against the water-separating body 400. The positioning pin 810 is connected to the other end of the first elastic member 820. The first elastic member 820 may be a compression spring.

When the spool 500 is located at the third position, the detent pin 810 is located in the first recess 721. When the valve spool 500 is located at the fourth position, the positioning pin 810 is positioned in the second recess 722. The valve core 500 can be selectively positioned at the third position or the fourth position by the cooperation of the first and

second recesses

721 and 722 and the positioning pin 810, and the valve core 500 is prevented from being accidentally moved to cause the accidental connection or blocking between the first water flow passage 2100 and the introduction passage 310.

As shown in fig. 13 and 14, fig. 13 isbase:Sub>A cross-sectional view taken along section linebase:Sub>A-base:Sub>A of fig. 1 with the valve cartridge 500 in the third position. Fig. 14 is a cross-sectional view taken along section line B-B of fig. 1, with the valve spool 500 in a third position. In the present embodiment, the user can operate the push button 710 to move the valve element 500 to the third position, and when the valve element 500 is at the third position, the positioning pin 810 is positioned in the first recess 721. When the valve core 500 is at the third position, the valve core 500 can block the first water flow passage 2100 and the introduction passage 310 so that water flow can not flow through the first water flow passage 2100 and can flow out of the housing through the second water flow passage 2200.

Next, the mode of sealing the valve body 500 and the introduction pipe 300 will be described in detail with reference to fig. 15.

As shown in fig. 15, fig. 15 is a partially enlarged view at L in fig. 13. Referring to fig. 12 and 15, in fig. 12, the valve body 500 is located at a fourth position, in which the valve body 500 is spaced apart from the introduction pipe 300, so that the first water passage 2100 communicates with the introduction passage 310. As shown in fig. 15, the valve body 500 is located at the third position, and the first sealing ring 355 is provided between the valve body 500 and the introduction pipe 300, so that the first water passage 2100 is not communicated with the introduction passage 310.

As shown in fig. 16 to 18, fig. 16 is a schematic view of the structure of fig. 4 with the container 100 removed. Fig. 17 is a schematic view of the structure of fig. 5 with the container 100 removed. Fig. 18 is a partial enlarged view at M in fig. 16. The water outlet device of the embodiment of the invention is not provided with the container 100, and at this time, the introducing pipe 300 is not pressed by the container 100 and moves to the second position by being pressed by the second elastic element 410. When the inlet pipe 300 is located at the second position, the second sealing ring 356 and the third sealing ring 357 are sealed between the inlet pipe 300 and the water diversion body 400, so that the first water flow passage 2100 and the inlet passage 310 are not communicated with each other, and water cannot enter the inlet passage 310 through the opening 360 of the inlet pipe 300.

In addition, the fourth ring groove 354 of the inlet pipe 300 is further provided with a fourth sealing ring 358, and the fourth sealing ring 358 is sealed between the fixing member 200 and the inlet pipe 300, so that the water flowing along the second water flow passage 2200 is prevented from flowing backwards and leaking out of the water outlet device from the gap between the fixing member 200 and the inlet pipe 300, and the sealing performance of the water outlet device according to the embodiment of the invention is further ensured.

That is, when the container 100 is not mounted, the water discharge apparatus according to the embodiment of the present invention may be used according to a general spray head. When the container 100 is installed, the water outlet device according to the embodiment of the present invention may combine the functional substance with the micro bubble water, further enhancing the effect of the functional substance.

Of course, it should be understood that the first water flow passage 2100 and the introduction passage 310 do not communicate with each other when the introduction tube 300 is located at the second position. At this time, whether the spool 500 is in the third position or the fourth position, the design in which the first water passage 2100 and the introduction passage 310 are not communicated with each other is not affected.

As shown in fig. 3 and 11, the outlet device further includes a check valve 420 downstream of the outlet channel 320, and the check valve 420 is used for preventing the water from flowing reversely.

As shown in fig. 19, in a modified embodiment, the container 100 is detachably disposed in the water outlet device, for example, the container 100 may have a tubular shape and be disposed in a handle portion 1140 of the water outlet device, and the handle portion 1140 may be detachably connected to the spraying portion 1160 through a threaded structure, so as to facilitate the detachment and installation of the container 100. The container 100 has two openings 101, and the liquid supplied from the water supply pipe can sequentially pass through the two openings 101, thereby taking out the functional substances such as the essential oil stored in the container 100 to continue flowing into the microbubble generator 1300 in the spraying section 1160, thereby generating the microbubble water with the essential oil.

As shown in fig. 20, in another modified embodiment, the introducing structure is a suction passage 910, and the suction passage 910 communicates with the inside of the container 100 and the micro bubble generating tube 1341, respectively. When the liquid supplied from the water supply pipe flows through the micro bubble generating tube 1341, the functional substance can be sucked into the first water flow channel 2100.

Specifically, the microbubble generation tube 1341 may be a flow path having a gradually increasing cross-sectional area in the water flow direction, or may be a flow path having a stepped cross-sectional area in the water flow direction. When the water stream flows through the microbubble generation tube 1341, microbubble water is generated due to a difference in air solubility caused by a pressure difference. When the hot water supplied from the water supply pipe passes through the microbubble generation tube 1341, the pressure at the small diameter of the microbubble generation tube is reduced, and the essential oil stored in the container 100 is sucked into the microbubble generation tube, as is known from the venturi principle, and the microbubble water with the essential oil is finally formed.

As shown in fig. 21, in a further modified embodiment, the introducing structure is a suction channel 910, the water outlet device further includes a suction channel 920, the suction channel 910 is respectively connected to the inside of the container 100 and the micro-bubble generating tube 1341, the suction channel 920 is connected to the micro-bubble generating tube 1341, and the outside air can enter the micro-bubble generating tube 1341 through the suction channel 920.

Particularly, when water flows through the small-diameter part of the microbubble generation tube, the water flow is accelerated, and according to the venturi principle, certain negative pressure is generated in the small-diameter part, so that the essential oil in the container 100 is sucked through the suction channel 910, and the external air is sucked through the suction flow channel 920, so that the air, the water flow and the essential oil are fully mixed in the microbubble generation tube, and finally, the microbubble water with the essential oil is formed.

As shown in fig. 22 and 23, fig. 22 is a schematic structural diagram of a microbubble generator according to an embodiment of the present invention. Fig. 23 shows a cross-sectional view along section line D-D in fig. 22. The microbubble generator 1300 according to the embodiment of the present invention includes a base portion 1320, a protrusion portion 1340, and a side stopper portion 1360, the base portion 1320 may have a substantially disk shape, the protrusion portion 1340 is provided on one side of the base portion 1320, and the microbubble generation tube 1341 is provided on the protrusion portion 1340. The side stops 1360 may be provided on the outer periphery of the base portion 1320.

Of course, it is understood that the base portion 1320 may not be a complete disk, for example, the base portion 1320 of the present embodiment further has a notch 1321, and the notch 1321 is used for disposing other components of the water outlet device therein, so as to avoid the base portion 1320 interfering with other components.

It should be understood that the shape of the base body 1320 is not limited to a disk shape, and the base body may have other shapes and may be adapted to the shape of the spraying portion 1160, which are not listed here.

When the base portion 1320 is disc-shaped, the base portion 1320 defines an axial direction Q, a radial direction S, and a radial plane P perpendicular to the axial direction Q. Wherein the axial direction Q and the radial direction S are perpendicular to each other.

As shown in fig. 4, the surface cover 1500 includes a cover 1520 and a side portion 1540, the side portion 1540 is disposed at an outer periphery of the cover 1520, the cover 1520 has a plurality of water outlet holes 1521, and the water outlet holes 1521 are capable of spraying micro-bubble water along the second water flow direction D2. The plurality of outlet holes 1521 may be uniformly arranged in a radial shape on the cover 1520. Since the outer periphery of the cover 1520 has a larger diameter than the inner periphery, the number of the outlet holes 1521 in the outer periphery of the cover 1520 is larger than the number of the outlet holes 1521 in the inner periphery.

When the cover 1500 is connected to the spraying portion 1160, the side portion 1540 can be connected to the spraying portion 1160 and disposed adjacent to a water outlet end of the microbubble generation tube 1341, and the side portion 1540 can buffer the microbubble water flowing out of the water outlet end, so that the microbubble generation tube 1341 can stably generate microbubbles. In the prior art or the related art, the arrangement mode that the first water flow direction is the same as the second water flow direction is adopted, and a baffle plate is often required to be arranged near the water outlet end of the micro bubble generating tube and plays a role in buffering micro bubble water. In the embodiment of the present invention, the micro-bubble water is ejected from the water outlet end and then directly collides with the side portion 1540 of the face cover 1500, so as to play a role of buffering the micro-bubble water without additionally providing a baffle.

Of course, it is understood that the side stop 1360 of the microbubble generator 1300 may also serve to buffer the water flow. The side barriers 1360 may function to buffer the micro bubble water together with the side 1540 of the surface cover 1500, or the side barriers 1360 may function to buffer the micro bubble water alone.

In an embodiment, the second water flow direction D2 may be parallel to the axial direction Q.

As shown in fig. 22 and 23, the number of the protruding portions 1340 is two, and the two protruding portions 1340 are disposed on the same side of the base 1320 and are arranged in a central symmetry manner with respect to the center point of the base 1320. Each protrusion 1340 is provided with four micro air bubble generating tubes 1341, and each micro air bubble generating tube 1341 sequentially includes a first flow passage 13411 and a second flow passage 13412 along the first water flow direction D1, wherein a flow passage sectional area of the first flow passage 13411 is smaller than a flow passage sectional area of the second flow passage 13412, so that an inner wall of the micro air bubble generating tube 1341 is formed in a stepped shape. When the water flow passes through the first flow passage 13411 having a smaller flow path sectional area, the flow velocity of the water flow increases; when the water flows through the second flow passage 13412 having a larger flow path sectional area, the flow velocity of the water decreases.

As shown in fig. 22, the base portion 1320 has a substantially disc shape and defines an axial direction Q, a radial direction S, and a radial plane P perpendicular to the axial direction Q. The first water flow direction D1 is parallel to the radial plane P, and an included angle β is formed between the first water flow direction D1 and the radial direction S. With such a design, since the extending direction (first water flow direction D1) of the microbubble generation tubes 1341 is not along the radial direction S but is inclined with respect to the radial direction S, the dimension of the base body 1320 in the radial direction S can be reduced as much as possible when the length of the microbubble generation tubes 1341 is constant.

In combination with the above-mentioned first water flow direction D1 and second water flow direction D2 mutually perpendicular, and first water flow direction D1 is parallel to radial plane P, and has the design of an included angle with radial direction S, under the prerequisite of guaranteeing the length dimension of microbubble generating tube 1341, can reduce as far as possible and spray portion 1160 along axial direction Q and radial direction S' S size, finally design the less portion 1160 that sprays of whole size.

Of course, it is understood that the microbubble generation tube 1341 may also have a horn shape. Specifically, the microbubble generation tube 1341 has a water inlet end and a water outlet end, and extends in the direction from the water inlet end to the water outlet end, so that the flow path cross-sectional area of the microbubble generation tube 1341 gradually increases.

It is to be understood that the number of the microbubble generation tubes 1341 is not particularly limited in the present invention, and those skilled in the art can increase or decrease the number of the microbubble generation tubes 1341 depending on the amount of water discharged.

The water flow direction in the water outlet device will be described in detail below by taking the embodiment shown in fig. 24 as an example. Fig. 24 is a cross-sectional view of the water outlet device according to an embodiment of the invention, in which the first water flow direction D1 is perpendicular to the second water flow direction D2. As shown in fig. 24, the first water flow direction D1 is substantially perpendicular to the second water flow direction D2, and the first water flow direction D1 in the microbubble generation tube 1341 flows from the inner periphery to the outer periphery of the microbubble generator 1300 until the flow reaches the vicinity of the outer periphery of the surface cover 1500, and is stopped and buffered by the side portion 1540. Then, a part of the microbubble water is emitted from the water outlet hole 1521 provided near the outer periphery of the face cover 1500, and the other part of the microbubble water flows toward the inner periphery of the face cover 1500 along the gap 1600 between the microbubble generator 1300 and the face cover 1500, and is gradually emitted from the water outlet hole 1521 in the process of flowing inward.

Because the plurality of water outlet holes 1521 are uniformly arranged on the surface cover 1500 in a radial manner, the outer circumference of the surface cover 1500 is larger than the inner circumference, so that the number of the water outlet holes 1521 near the outer circumference of the surface cover 1500 is larger than the number of the water outlet holes 1521 near the inner circumference. Therefore, most of the generated micro-bubble water can be ejected from the outer periphery of the face cover 1500 provided with a large number of the water outlet holes 1521, and a small part of the micro-bubble water is ejected from the inner periphery of a small number of the water outlet holes 1521. Compared with the scheme that most of micro bubble water is concentrated on the inner periphery of the surface cover 1500 in the prior art or the related art, the water outlet mode of the embodiment of the invention enables the water outlet of the inner periphery and the outer periphery of the surface cover 1500 to be more uniform.

Of course, it is understood that the first water flow direction D1 and the second water flow direction D2 can also be set in the manner of the embodiment shown in fig. 25. Fig. 25 is a cross-sectional view of the water outlet device according to an embodiment of the invention, wherein an acute angle is formed between the first water flow direction D1 and the second water flow direction D2. As shown in fig. 25, an acute angle α 1 is formed between the first water flow direction D1 and the second water flow direction D2, and the acute angle may be greater than or equal to 45 degrees and less than 90 degrees, and further, the acute angle is greater than or equal to 80 degrees and less than 90 degrees, such as 81 degrees, 82 degrees, 83 degrees, 84 degrees, 85 degrees, 86 degrees, 87 degrees, 88 degrees, and 89 degrees.

Of course, it can be understood that, as shown in fig. 26, fig. 26 is a cross-sectional view of the water outlet device according to an embodiment of the present invention, wherein an obtuse angle is formed between the first water flow direction D1 and the second water flow direction D2. The first water flow direction D1 and the second water flow direction D2 have an obtuse angle α 2 therebetween, the obtuse angle may be greater than 90 degrees and equal to or less than 120 degrees, and further, the obtuse angle may be greater than 90 degrees and equal to or less than 100 degrees, such as 91 degrees, 92 degrees, 93 degrees, 94 degrees, 95 degrees, 96 degrees, 97 degrees, 98 degrees, and 99 degrees.
