Description

Technical Field

[0001] This invention relates to the field of kitchen and bathroom technology, and in particular to a water outlet device. Background Technology

[0002] The water outlet device in the kitchen or bathroom connects to the faucet body on the sink via a flexible hose at the end. Designed for easy handling, it has a water outlet at one end of the housing, and a water switching component on the housing switches the water path, allowing the device to achieve different water dispensing modes. Existing water outlet devices with three functions require at least two buttons on the housing, which is not only inconvenient to operate but also results in a complex internal structure, a bulky overall design, and an unsightly appearance. Furthermore, because the valve body and the switching component are generally connected by a bone-shaped ball joint, improper switching can easily lead to leaks.

[0003] Therefore, it is necessary to provide a new water outlet device to solve or at least alleviate the aforementioned technical defects. Summary of the Invention

[0004] The main objective of this invention is to provide a water outlet device that addresses the technical problems of unattractive appearance and leakage issues in existing water outlet devices.

[0005] To achieve the above objectives, the present invention provides a water outlet device, including a housing and an inlet, a first outlet, a second outlet, and a third outlet disposed in the housing. An inlet channel, a first outlet channel, a second outlet channel, and a third outlet channel are formed within the housing. The first outlet channel connects the inlet channel and the first outlet, the second outlet channel connects the inlet channel and the second outlet, and the third outlet channel connects the inlet channel and the third outlet.

[0006] It also includes a switching component, which includes a switching button, a first valve body, and a second valve body. The first valve body has a snap-fit ​​on the side near the switching button, and the switching button has a snap-fit ​​position that engages with the snap-fit. The first valve body is connected to the switching button to open or close the first water outlet channel. The switching button is connected to the second valve body to switch the second valve body to a first working position or a second working position. When the second valve body is in the first working position, the second valve body opens the second water outlet channel and closes the third water outlet channel. When the second valve body is in the second working position, the second valve body closes the second water outlet channel and opens the third water outlet channel.

[0007] In one embodiment, the first valve body includes a spindle and an elastic element. The spindle is connected to the switching button, one end of the elastic element abuts against the housing, and the other end of the elastic element abuts against the spindle. The elastic element is used to provide an elastic force for the spindle to reset.

[0008] In one embodiment, the switching button includes a hinge portion and a first pressing end and a second pressing end respectively disposed on both sides of the hinge portion. The hinge portion is hinged to the housing, the first pressing end is connected to the spindle, and the second pressing end is connected to the second valve body.

[0009] In one embodiment, the end of the mandrel near the switch button is formed into a tapered end, the buckle includes an annular step disposed on the bottom surface of the tapered end, the snap-fit ​​position includes a snap-fit ​​groove and a protruding end disposed on the inner sidewall of the snap-fit ​​groove, the tapered end is disposed in the snap-fit ​​groove, and the bottom surface of the protruding end abuts against the top surface of the annular step to prevent the tapered end from sliding out of the snap-fit ​​groove.

[0010] In one embodiment, the second valve body includes a switching shaft, a water distribution plate, and a reset member. A first water passage hole and a second water passage hole are formed inside the housing. The first water passage hole is formed in the second water outlet channel, and the second water passage hole is formed in the third water outlet channel. The switching shaft is connected to the switching button. The water distribution plate is fitted onto the switching shaft. One end of the reset member abuts against the housing, and the other end of the reset member is connected to the water distribution plate. The reset member is used to drive the water distribution plate and the switching shaft to reset when the external force is removed, and to drive the water distribution plate to rotate so as to drive the water distribution plate to close one of the first water passage hole or the second water passage hole.

[0011] In one embodiment, a limiting member is provided inside the housing, and a snap-fit ​​end is formed on the water distribution plate. The limiting member includes a limiting shaft and at least two limiting ends arranged around the limiting circumference. A limiting groove is formed between two adjacent limiting ends, and the snap-fit ​​end is used to snap into the limiting groove.

[0012] In one embodiment, the water distribution plate is provided with a plurality of snap-fit ​​ends spaced apart along the circumference. The limiting member includes a limiting shaft and a plurality of limiting ends spaced apart around the limiting shaft. A limiting groove is formed between two adjacent limiting ends. The number of limiting grooves is equal to the number of snap-fit ​​ends and is provided in a one-to-one correspondence. Each snap-fit ​​end can be rotated to snap into any of the limiting grooves.

[0013] In one embodiment, a snap-fit ​​guide surface is formed on the side of the snap-fit ​​end facing the limiting end, and a limiting guide surface is formed at the opening of the limiting groove to cooperate with the snap-fit ​​guide surface, so that when the water distribution plate rotates, the snap-fit ​​end rotates into the limiting groove along the limiting guide surface; the limiting end is located on one side of the limiting groove and a limiting surface is formed, and the limiting surface is vertically arranged.

[0014] In one embodiment, the water distribution plate includes a connecting portion and a sealing portion connected to the connecting portion. The connecting portion is fitted onto the switching shaft, and the sealing portion is used for sealing engagement with one of the first water passage holes or the second water passage hole.

[0015] In one embodiment, the first water passage hole and the second water passage hole are arranged adjacent to each other, and there are two sealing closure parts, which are respectively arranged on opposite sides of the connecting part.

[0016] In the above scheme, the water outlet device includes three water outlet modes, making it a three-function water outlet device. A switching button is used to switch the water outlet device between the three modes. A first valve chamber and a second valve chamber are formed within the housing. The first valve body is movably disposed within the first valve chamber, and the second valve body is movably disposed within the second valve chamber. Specifically, the first valve body controls the closing or opening of the first water outlet channel. When the first valve body is open, water entering from the inlet flows through the inlet channel into the first water outlet channel and exits from the first water outlet. When the first valve body is closed, the water in the inlet channel can achieve two different water outlet modes by switching the working position of the second valve body using the switching button. Specifically, when the switching button switches the second valve body to the first working position, the second valve body opens the second water outlet channel and closes the third water outlet channel, allowing water to flow out from the second water outlet. When the second valve body is in the second working position, the second valve body closes the second water outlet channel and opens the third water outlet channel, allowing water to flow out from the third water outlet, thus achieving three water outlet functions. This embodiment achieves water circuit switching by driving the second valve body to different working positions via a switching button. Furthermore, a single button enables switching between three functions, simplifying the internal water circuit structure, achieving a flattened structure for the water outlet device, and improving its aesthetics. Moreover, by setting an inverted snap-fit ​​connection on the first valve body to engage with the switching button, the connection has less room for movement after completion. Compared to a bone-shaped ball joint connection, this allows for more precise stroke control of the first valve body during subsequent switching processes, preventing leakage caused by incomplete movement of the first valve body. This invention offers the advantages of both aesthetic appeal and leak-proof performance. Attached Figure Description

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

[0036] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.

[0037] See Figures 1-12The present invention provides a water outlet device, including a housing 2 and an inlet 21, a first outlet 22, a second outlet 23, and a third outlet 24 disposed in the housing 2. An inlet channel 28, a first outlet channel 25, a second outlet channel 26, and a third outlet channel 27 are formed within the housing 2. The first outlet channel 25 connects the inlet channel 28 and the first outlet 22; the second outlet channel 26 connects the inlet channel 28 and the second outlet 23; and the third outlet channel 27 connects the inlet channel 28 and the third outlet 24. The device also includes a switching assembly, which comprises a switching button 3, a first valve body 4, and a second valve body 5. The valve body 5 has a buckle 44 on the side of the first valve body 4 near the switching button 3, and the switching button 3 has a snap-fit ​​position that engages with the buckle 44. The first valve body 4 is connected to the switching button 3 to open or close the first water outlet channel 25. The switching button 3 is connected to the second valve body 5 to switch the second valve body 5 to the first working position or the second working position. When the second valve body 5 is in the first working position, the second valve body 5 opens the second water outlet channel 26 and closes the third water outlet channel 27. When the second valve body 5 is in the second working position, the second valve body 5 closes the second water outlet channel 26 and opens the third water outlet channel 27.

[0038] In the above embodiment, the water outlet device includes three water outlet modes, making it a three-function water outlet device. The switching button 3 is used to switch the water outlet device between the three water outlet modes. A first valve chamber 13 and a second valve chamber 14 are formed within the housing 2. The first valve body 4 is movably disposed within the first valve chamber 13, and the second valve body 5 is movably disposed within the second valve chamber 14. Specifically, the first valve body 4 is used to control the closing or opening of the first water outlet channel 25, as described above. Figure 3 and Figure 4 When the first valve body 4 is opened, the water entering from the inlet 21 passes through the inlet channel 28 and then... Figure 4 The water flows into the first outlet channel 25 through the S1 outlet and finally flows out through the first outlet 22. The water flow direction diagram is shown below. Figure 10As indicated by the arrows and solid lines. When the first valve body 4 is closed, the water in the inlet channel 28 can be switched to two different water outlet modes by changing the working position of the second valve body 5 using the switch button 3. It should be noted that closing the first valve body 4 here refers to closing the connection between the inlet channel 28 and the first outlet channel 25, not closing the entire water outlet device. Specifically, when the first valve body 4 is closed, the water entering from the inlet 21 flows into the second valve body through the outlet S2. When the switch button 3 switches the second valve body 5 to the first working position, the second valve body 5 opens the second outlet channel 26 and closes the third outlet channel 27, and the water flows out from the second outlet 23. When the second valve body 5 is in the second working position, the second valve body 5 closes the second outlet channel 26 and opens the third outlet channel 27, and the water flows out from the third outlet 24, thus realizing three water outlet functions. This embodiment achieves water circuit switching by driving the second valve body 5 to different working positions via the switching button 3. Furthermore, only one switching button 3 is needed to switch between three functions, simplifying the internal water circuit structure, achieving a flattened structure for the water outlet device, and improving its aesthetics. Moreover, by setting an inverted buckle 44 on the first valve body 4 to engage with the switching button 3, the mobility after connection is reduced. Compared to a bone-shaped ball joint connection, the stroke control of the first valve body 4 is more precise during subsequent switching, avoiding water leakage caused by incomplete movement of the first valve body 4. Specifically, the water outlet device can be a faucet or a showerhead. This invention has the advantages of aesthetic appearance and leak-proof design.

[0039] Reference Figures 1-6 In one embodiment, the first valve body 4 includes a spindle 42 and an elastic element 43. The spindle 42 is connected to a switching button 3. One end of the elastic element 43 abuts against the housing 2, and the other end of the elastic element 43 abuts against the spindle 42. The elastic element 43 provides the elastic force for the spindle 42 to reset. The switching button 3 drives the spindle 42 to move and open the first valve body 4, allowing water in the inlet channel 28 to flow to the first outlet channel 25. At this time, the elastic element 43 deforms and stores energy. It should be noted that when the first valve body 4 closes the first inlet channel 28, and the second valve body 5 opens the second outlet channel 26 or the third outlet channel 27, due to the water pressure in the first valve chamber 13, the spindle 42 will overcome the action of the elastic element 43 under the water pressure, maintaining the water flow in the second valve chamber 14. Here, the elastic element 43 can be a spring.

[0040] Reference Figures 3-6In one embodiment, the switching button 3 includes a hinge portion 33 and a first pressing end 31 and a second pressing end 32 respectively disposed on both sides of the hinge portion 33. The hinge portion 33 is hinged to the housing 2, the first pressing end 31 is connected to the spindle 42, and the second pressing end 32 is connected to the second valve body 5. The hinge portion 33 forms a seesaw-like structure, allowing the buttons to be integrated together. A single switching button 3 can control the opening and closing of the first valve body 4, as well as the switching between the first and second working positions of the second valve body 5.

[0041] Reference Figure 2 In one embodiment, the end of the mandrel 42 near the switch button 3 is formed as a tapered end 41. The snap fastener 44 includes an annular step 441 disposed on the bottom surface of the tapered end 41. The locking position includes a locking groove 311 and a protruding end 312 disposed on the inner sidewall of the locking groove 311. The tapered end 41 is disposed in the locking groove 311, and the bottom surface of the protruding end 312 abuts against the top surface of the annular step 441 to prevent the tapered end 41 from sliding out of the locking groove 311. The section of the mandrel 42 near the switch button 3 is formed as a tapered end 41, and the tip of the tapered end 41 faces the switch button 3, which facilitates insertion into the locking position. The annular step 441 is provided on the bottom surface of the tapered end 41 to engage with the protruding end 312, making it difficult for the tapered end 41 to disengage from the locking groove 311, ensuring the firmness and rigidity of the connection.

[0042] Reference Figures 1-6 and Figure 9 In one embodiment, the second valve body 5 includes a switching shaft 51, a water distribution plate 52, and a reset member 53. A first water passage hole 6 and a second water passage hole 7 are formed inside the housing 2. The first water passage hole 6 is formed in the second water outlet channel 26, and the second water passage hole 7 is formed in the third water outlet channel 27. The switching shaft 51 is connected to the switching button 3. The water distribution plate 52 is fitted onto the switching shaft 51. One end of the reset member 53 abuts against the housing 2, and the other end of the reset member 53 is connected to the water distribution plate 52. The reset member 53 is used to drive the water distribution plate 52 and the switching shaft 51 to reset when the external force is removed, and to drive the water distribution plate 52 to rotate so as to drive the water distribution plate 52 to close one of the first water passage hole 6 or the second water passage hole 7. The second water outlet channel 26 and the third water outlet channel 27 are controlled by the water distribution plate 52. When the water distribution plate 52 closes the first water passage 6, the second water passage 7 opens, that is, the second water outlet channel 26 is closed and the third water outlet channel 27 is opened, and water flows out from the third outlet. The water flow direction is shown in the diagram below. Figure 12 As indicated by the middle arrow and solid line. When the water distribution plate 52 closes the second water passage 7, the first water passage 6 opens, meaning the third water outlet channel 27 closes and the second water outlet channel 26 opens, allowing water to flow out from the second outlet. The water flow direction is shown in the diagram below. Figure 11As indicated by the middle arrow and solid line. Specifically, when an external force pushes the second pressing end 32, the reset member 53 deforms and stores energy. When the external force is removed, the reset member 53 drives the water distribution plate 52 to move. However, since the reset member 53 and the water distribution plate 52 are not aligned, the eccentric force of the reset member 53 will also drive the water distribution plate 52 to rotate around the switching shaft 51, so that the water distribution plate 52 can selectively close one of the first water passage hole 6 or the second water passage hole 7, thereby corresponding to two different water outlet states.

[0043] Reference Figure 1 and Figure 9 In one embodiment, a limiting member is provided inside the housing 2, and a snap-fit ​​end 54 is formed on the water distribution plate 52. The limiting member includes a limiting shaft and at least two limiting ends 8 arranged around the limiting circumference. A limiting groove 9 is formed between two adjacent limiting ends 8, and the snap-fit ​​end 54 is used to snap into the limiting groove 9. When the snap-fit ​​end 54 is snapped into the limiting groove 9, it indicates that the movement state has stabilized. At this time, the water outlet plate closes the first water passage 6 or the second water passage 7, and the second water outlet channel 26 or the third water outlet channel 27 is opened. The snap-fit ​​end 54 and the limiting member mainly serve to ensure a firm snap-fit ​​and stabilize the water outlet state. When it is necessary to switch the water outlet state, the second pressing end 32 is pressed by external force to drive the switching shaft 51 to move, so that the water distribution plate 52 connected to the switching shaft 51 and the snap-fit ​​end 54 on the water distribution plate 52 disengage from the limiting groove 9, which facilitates the switching of another water outlet state. It should be noted that in this embodiment, there may be only one card connector 54, which can be inserted into different limiting slots 9 to achieve a stable connection.

[0044] Reference Figure 1 and Figure 9 In one embodiment, the water distribution plate 52 is provided with multiple snap-fit ​​ends 54 spaced circumferentially. The limiting member includes a limiting shaft and multiple limiting ends 8 spaced apart around the limiting shaft. A limiting groove 9 is formed between two adjacent limiting ends 8. The number of limiting grooves 9 is equal to the number of snap-fit ​​ends 54 and is arranged in a one-to-one correspondence. Each snap-fit ​​end 54 can be rotated to snap into any limiting groove 9. As another implementation of the above embodiment, there are multiple snap-fit ​​ends 54 and limiting members. The number of limiting grooves 9 is equal to the number of snap-fit ​​ends 54, and multiple snap-fit ​​ends 54 can be snapped into all limiting grooves 9 at the same time, so the snap-fit ​​is more stable. Of course, each snap-fit ​​end 54 can also be rotated to snap into any limiting groove 9, which facilitates switching the water outlet state. Of course, the driving force for the rotation of the snap-fit ​​end 54 comes from the rotation drive of the aforementioned reset member 53 on the water distribution plate 52.

[0045] Reference Figure 9In one embodiment, the snap-fit ​​end 54 has a snap-fit ​​guide surface 541 on the side facing the limiting end 8, and a limiting guide surface 81 is formed at the opening of the limiting groove 9 to cooperate with the snap-fit ​​guide surface 541, so that when the water distribution plate 52 rotates, the snap-fit ​​end 54 rotates into the limiting groove 9 along the limiting guide surface 81; the limiting end 8 has a limiting surface 82 on one side of the limiting groove 9, and the limiting surface 82 is vertically arranged. Specifically, both the snap-fit ​​guide surface 541 and the limiting guide surface 81 are inclined surfaces, which serve to guide the snap-fit ​​end 54 to rotate into the limiting groove 9. The limiting surface 82 is the side wall of the limiting groove 9 and is vertically arranged to prevent the snap-fit ​​end 54 from slipping out after snapping into the limiting groove 9, ensuring a firm snap-fit.

[0046] Reference Figures 3-4 ,and Figures 7-9 In one embodiment, the water distribution plate 52 includes a connecting portion 521 and a sealing portion 522 connected to the connecting portion 521. The connecting portion 521 is fitted onto the switching shaft 51, and the sealing portion 522 is used for a sealing engagement with one of the first water passage holes 6 or the second water passage hole 7. Specifically, the first water passage hole 6 and the second water passage hole 7 are arranged adjacent to each other, and there are two sealing portions 522, which are respectively arranged on opposite sides of the connecting portion 521. The sealing engagement here means that when the sealing portion 522 engages with the first water passage hole 6 or the second water passage hole 7, water flow will be prevented, thus closing the second or third water passage. There are two sealing parts arranged opposite each other. The area of ​​each sealing part occupies one-quarter of the circumference area. The first water passage 6 and the second water passage 7 are the same in shape and size, and are arranged adjacent to each other. The first water passage 6 or the second water passage 7 also occupies one-quarter of the circumference area. The shape of the first water passage 6 and the second water passage 7 is adapted to the shape of the sealing part. This ensures that when one sealing part is sealed with one water passage, the other water passage must be open; or, when one sealing part is fully open with one water passage, the other water passage must be sealed with the sealing part. This ensures that water can only flow out from one of the second water outlet channel 26 or the third water outlet channel 27.

[0047] The principle of the present invention is explained below: A fixing seat 10, a base 11, and a sealing gasket 12 are provided inside the housing 2, as shown in the following description. Figures 3-4 and Figure 10 In the initial state, the spindle 42, under the action of the elastic element 43, presses against the base 11, causing water to flow from the water channel to the first outlet 22, completing one default water dispensing cycle. (Refer to...) Figures 5-6When a switching force F is applied to the second pressing end 32, the second pressing end 32 will drive the first pressing end 31 to rotate around the pin of the hinge part 33. At the same time, the second pressing end 32 and the spindle 42 form a reverse buckle 44 at the snap point, causing the spindle 42 to be lifted, thereby moving the sealing gasket 12 to the fixed seat 10, realizing the water circuit switching, and the water circuit enters the second valve chamber 14. (Refer to...) Figure 11 and Figure 12 The second valve chamber 14 is connected to at least the second water outlet channel 26 and the third water outlet channel 27. The water outlets are controlled by the water distribution plate 52. The water distribution plate 52 is coaxial with the switching shaft 51, and the two are in contact with the limiting surface 82 on the base 11. When the external force drives the second pressing end 32, it will drive the switching shaft 51 and the water distribution plate 52 to move along the limiting surface 82 of the limiting groove 9 on the base 11. When the switching shaft 51 and the water distribution plate 52 move to the limiting surface 82 of the limiting groove 9, the water distribution plate 52 will rotate downward at a certain angle under the action of the reset member 53, and then fall on the limiting guide surface 81 of the limiting end 8. It will continue to rotate at a certain angle until the water distribution plate 52 falls into the limiting surface 82 of another limiting groove 9, completing one water circuit switching. At this time, due to the water pressure in the first cavity, the spindle 42 will overcome the elasticity and keep the second valve cavity 14 in a water-flow state. If an operating force is applied, such as pressing the first pressing end 31, the spindle 42 will reset, and the water circuit will be reset to the first water outlet state, flowing out from the first water outlet 22. Alternatively, if the water inlet is closed, the spindle 42 will reset, and no water will flow through.

[0048] The above are merely optional embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
