Description

TECHNICAL FIELD

[0001] The utility model relates to sanitary ware products, especially water outlet device. BACKGROUND

[0002] In the traditional kitchen shower, there is only one water outlet end, several groups of water outlet holes with different water effect are arranged on the water outlet end, and different water outlet holes are switched by a switching assembly. The disadvantage of this way is that all the water outlet holes are arranged together and occupy space, resulting in that the water outlet area of each water flow is not large enough to meet the needs of users.

[0003] Therefore, some faucets with two water outlet ends appear on the market, which ensure that each water flow has sufficient coverage area by arranging water outlet holes with different water flows on different water outlet ends. However, this faucet needs to set an additional switching operating part on the body to operate and switch different water outlet holes, which is troublesome. In addition, the switching of the two water outlet ends of this faucet often causes user's misoperation, and the learning cost is relatively high. UTILITY MODEL CONTENTS

[0022] This utility model also provides a faucet equipped with the water outlet device described above.

[0023] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0024] This utility model provides a water outlet device. The water outlet arm moves between the storage position and the use position, and the linkage switching component moves to switch whether water is coming out of the first outlet or the second outlet. There is no need to set an additional operating component on the faucet to operate the water outlet. The linkage switching is simple and convenient. In addition, the structure is simple and compact, with few parts and low cost, because the linkage switching component moves.

[0025] Furthermore, by setting a free-spinning stroke on the switching assembly, the switching assembly will not engage with the switching component when it is within this free-spinning stroke, thus preventing the water path switching effect from being triggered. Therefore, the switching component will only perform water path switching after it has passed this free-spinning stroke and continues to move. This avoids the inconvenience of the water outlet arm dispensing water at the beginning of its rotation. Moreover, when shutting off the water, the water outlet arm shuts off the water by moving the switching assembly from the third position to the second position. Therefore, the shut-off stroke is relatively short, allowing for rapid water shut-off by the water outlet arm. Attached Figure Description

[0041] To make the technical solution and features of this utility model clearer, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific examples. It should be understood that these examples are only for illustrating this utility model and are not intended to limit the scope of this utility model. After reading this utility model, any modifications of this utility model by those skilled in the art in various equivalent forms fall within the scope defined by the appended claims.

[0042] refer to Figures 1-11 This embodiment provides a kitchen faucet, including a faucet mounting base 1, a bend 2, a pull-out pipe 3, and a water outlet device 4 connected to one end of the pull-out pipe 3. The installation structure of the kitchen faucet is existing technology, and this application does not modify it; therefore, it will not be described in detail. The improvement of this application lies in the water outlet device 4 connected to the pull-out pipe 3. Traditional water outlet devices 4 have only one water outlet end, and different water outlets on one end are switched using a function switching component to create different water spray patterns. However, the water outlet device 4 in this embodiment has different water outlet ends, and the function switching component allows different water outlets to be used. The independent operation of each water outlet end ensures that each water spray pattern has a sufficiently large coverage area.

[0043] Therefore, the water outlet device 4 in this embodiment includes: a water outlet device body 41, and a water outlet support arm 42 movably connected to the water outlet device body 41. The water outlet support arm 42 has a use position and a storage position relative to the water outlet device body 41. The water outlet device body 41 is provided with a first flow channel 411 and a second flow channel 412. The first flow channel 411 is connected to a first water outlet 413 provided on the water outlet device body 41, and the second flow channel 412 is connected to a second water outlet 421 provided on the water outlet support arm 42. In this embodiment, the water outlet support arm 42 is rotatably connected to the water outlet device body 41. The water outlet support arm 42 rotates in a vertical plane relative to the water outlet device body 41. When the water outlet support arm 42 is in the storage position, the water outlet support arm 42 is attached to the side of the water outlet device body 41. When the water outlet support arm 42 is in the use position, the water outlet support arm 42 opens outward relative to the water outlet device body 41. The side of the water outlet device body 41 is provided with a cavity 414 for accommodating the water outlet support arm 42. When the water outlet support arm 42 is in the retracted position, it is placed within the cavity 414. Thus, when the water outlet support arm 42 is retracted, it fills the cavity 414, the side 423 of the water outlet support arm 42 fits against the stepped surface 416 of the body 41, and the upper top surface 422 of the water outlet support arm 42 is on the same plane as the circumferential surface 415 of the water outlet device body 41, thereby integrating it with the body 41 into a single unit with good visual consistency. In this embodiment, the water outlet support arm 42 rotates relative to the water outlet device body 41 in a vertical plane as an example. As a simple alternative to this embodiment, the water outlet support arm 42 can also rotate relative to the water outlet device body 41 in a horizontal plane or other planes.

[0044] In this embodiment, the water outlet arm 42 needs to rotate a certain distance from its retracted position before water can be discharged. This avoids water splashing and causing inconvenience to the user as soon as the water outlet arm 42 is removed from its retracted position. To this end, the water outlet device body 41 and the water outlet arm 42 are respectively provided with a switching component 415 and a switching engagement component 424. The switching engagement component 424 rotates with the water outlet arm 42 relative to the switching component 415 between a first position, a second position, and a third position. The first position corresponds to the retracted position of the water outlet arm 42, at which time the first flow channel 411 is open and water is discharged, while the second flow channel 412 is sealed and no water is discharged. The third position corresponds to the fully open use position of the water outlet arm 42, at which time the first flow channel 411 is sealed and no water is discharged, while the second flow channel 412 is open and water is discharged. The second position is the position where the water outlet arm 42 is open but not fully open. When the switching engagement component 424 moves between the second and third positions, the switching engagement component 424 and the switching component 415 are in a linkage engagement to connect the first flow channel 411 or the second flow channel 412 with the water inlet 410 of the water outlet device body 41. When the switching engagement component 424 moves between the first and second positions, the switching component 415 and the switching engagement component 424 are in a non-linkage engagement state. That is, when the switching engagement component 424 moves between the first and second positions, it has a free-spinning stroke, so that when the switching engagement component 424 is within the free-spinning stroke, it will not form a linkage engagement with the switching component 415, and thus will not trigger the water path switching effect. Therefore, the switching component 415 will only perform water path switching after the switching engagement component 424 has passed this free-spinning stroke and continues to move, which can avoid the inconvenience caused by the water outlet support arm 42 discharging water at the beginning of rotation. Furthermore, when the water outlet support arm 42 drives the switching mating part 424 to reset from the third position to the second position, the water outlet support arm 42 achieves water shut-off. Therefore, the water shut-off stroke is relatively short, which can achieve rapid water shut-off by the water outlet support arm 42.

[0045] Specifically, the switching member 415 is provided with a first abutting surface 4151 and a second abutting surface 4152, and the switching mating member 424 is provided with a first abutting mating member 4241 and a second abutting mating member 4242. When the switching mating member 424 moves from the second position to the third position, the first abutting surface 4151 and the first abutting mating member 4241 form a reversing engagement, so as to change the rotation of the switching mating member 424 into the movement of the switching member 415 along the first direction. When the switching mating member 424 moves from the third position to the second position, the second abutting surface 4152 and the second abutting mating member 4242 form a reversing engagement, so as to change the rotation of the switching mating member 424 into the movement of the switching member 415 along the second direction. The first direction and the second direction are opposite. In this embodiment, the first direction is downward movement along the axial direction of the water outlet device body 41, and the second direction is upward movement along the axial direction of the water outlet device body 41. By using two different top abutting surfaces and top abutting mating parts, the switching mating part 424 can move from the second direction to the third direction, or from the third direction to the second direction. The switching mating part 424 and the switching part 415 can form a linkage, and the linkage is in opposite directions. This allows the switching part 415 to connect the first flow channel 411 or the second flow channel 412 with the water inlet 410 of the water outlet device body 41 when it moves in different directions.

[0046] Furthermore, the first abutting fitting 4241 and the second abutting fitting 4242 are spaced apart along the rotation direction of the switching fitting 424, and the length of the first abutting fitting 4241 is greater than the length of the second abutting fitting 4242. Thus, during the movement of the switching fitting 424 from the first position to the second position, the second abutting fitting 4242, being shorter, can pass over the first abutting surface 4151, preventing the second abutting fitting 4242 from contacting the first abutting surface 4151 and causing the switching fitting 415 to move prematurely. This ensures that only the first abutting fitting 4241 can engage with the first abutting surface 4151. Furthermore, when the switching engagement member 424 moves from the second position to the third position, since the switching engagement member 424 rotates around its axis, it undergoes displacement both along the axial direction of the water outlet device body 41 and perpendicular to the axial direction of the water outlet device body 41. Meanwhile, the first abutment surface 4151 and the second abutment surface 4152 only move along the axial direction of the water outlet device body 41. Therefore, when the switching engagement member 424 moves from the second position to the third position, the contact area between the first abutment engagement member 4241 and the first abutment surface 4151 gradually increases, while the second abutment engagement member 4242 also moves to the second abutment surface 4151. 52 is projected along the axial direction of the water outlet device body 41. Therefore, when the switching engagement member 424 moves from the third position to the second position, the second abutment engagement member 4242 can quickly engage with the second abutment surface 4152, and the contact area between the second abutment engagement member 4242 and the second abutment surface 4152 gradually decreases. When the switching engagement member 424 moves from the third position to the second position, the second abutment engagement member 4242 also moves outside the projection of the second abutment surface 4152 along the axial direction of the water outlet device body 41, and the linkage between the second abutment engagement member 4242 and the second abutment surface 4152 is released.

[0047] The switching component 415 includes a switching shaft 4153 and a movable component 4154 fixed to the side wall of the switching shaft 4153. The movable component 4154 is provided with a first abutment surface 4151 and a second abutment surface 4152 to drive the switching shaft 4153 to move along a first direction or a second direction. Alternatively, the movable component 4154 can be omitted, and the first abutment surface 4151 and the second abutment surface 4152 can be directly provided on the switching shaft 4153.

[0048] To install the movable component 4154 and the switching shaft 4153, the movable component 4154 has a first portion 41541 extending axially along the switching shaft 4153, and a second portion 41542 for connecting the switching shaft 4153. In this embodiment, one end of the second portion 41542 is connected to the first portion 41541, and the other end extends in a direction perpendicular to the axial direction of the switching shaft 4153. The second portion 41542 includes two spaced-apart connecting plates. The switching shaft 4153 has a concave ring 41531 extending axially inward. The concave ring 41531 is placed between the two connecting plates so that the upper and lower surfaces of the concave ring respectively engage with the upper and lower surfaces of the connecting plates. In this way, the switching shaft 4153 and the movable component 4154 are axially engaged and fixed together, while in a direction perpendicular to the axial direction, they can be separated and disassembled under external force.

[0049] To enable the switching component 415 to switch water channels, a sealing gasket 41532 is provided on the switching shaft 4153. During the movement of the switching mating component 424 from the first position to the second position, the sealing gasket 41532 always seals the connection between the second flow channel 412 and the water inlet 410. During the movement of the switching mating component 424 from the second position to the third position, the sealing gasket 41532 opens the connection between the second flow channel 412 and the water inlet 410 and seals the connection between the first flow channel 411 and the water inlet 410.

[0050] Furthermore, a return spring 4155 is fitted over the switching shaft 4153. During the movement of the switching mating member 424 from the second position to the third position, the switching shaft 4153 compresses the return spring 4155, accumulating elastic return force. Thus, when the water is turned off, the return spring 4155 releases the elastic return force, causing the switching shaft 4153 to move axially upwards. During this movement, the second abutment surface 4152 and the second abutment mating member 4242 work together to move the switching mating member 424 from the third position to the second position. This allows for automatic switching back to the first flow channel 411 when the water is turned off.

[0051] This embodiment uses a pull-out faucet as an example, but the water outlet device 4 described above can also be used on other fixed faucets or showerheads. In this embodiment, the water outlet 413 produces aerated water, and the water outlet 421 produces shower water. The water spray from both outlets is not limited to these and can be any other type of water spray.

[0052] Example 2

[0053] refer to Figures 13-15The difference between this embodiment and Embodiment 1 is that the switching component 424 is a gear 4243 mounted on the rotating shaft of the water outlet arm 42, and the switching component 415 is provided with a rack 417 extending axially along the body 41 of the water outlet device. Furthermore, the gear 4243 is divided into a region 42432 with tooth tips and a region 42431 without tooth tips along the rotation direction. When the gear 4243 rotates to the point where the region 42431 without tooth tips corresponds to the tooth tip on the rack 417, the rotation of the gear 4243 will not cause the rack 417 to move, thus forming an idle stroke.

[0054] Therefore, when the water outlet arm 42 is in the retracted position, the gear 4243 rotates to the area 42431 without tooth tips, forming a free-spinning engagement with the rack 417. Thus, during the process of the water outlet arm 42 opening outward from the retracted position, that is, during the rotation of the switching engagement component 424 from the first position to the second position, the gear 4243 and rack 417 are in a free-spinning engagement and do not form a linkage relationship. The rack 417 will not move downward along the axial direction of the water outlet device body 41 as the gear 4243 rotates. When the switching engagement component 424 moves to the second position, the gear 4243 rotates to the area 42432 with tooth tips, corresponding to the tooth tips of the rack 417. The gear 4243 and the rack 417 mesh together to form a linkage relationship. When the switching engagement part 424 continues to move from the second position to the third position, the gear 4243 drives the rack 417 to move downward along the axial direction of the water outlet device body 41, connecting the second flow channel 412 with the water inlet end of the water outlet device body 41, and the water outlet support arm 42 begins to discharge water.

[0055] The above is only one specific embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
