Description

Technical Field

[0001] The present invention relates to the technical field of bathroom products, and in particular to a switching faucet and a pull-out faucet. Background Art

[0002] Existing pull-out faucets usually have multiple water channels, and the outlet cover is provided with multiple water outlet holes corresponding to each water channel, each outlet hole produces a different type of water spray. The water channel is switched by controlling the switching valve core, thereby switching the water spray.

[0003] For example, Chinese patent CN210196557U discloses a multifunctional pull-out showerhead comprising a switching assembly and a water inlet assembly and a water outlet assembly connected to the water inlet / outlet ends of the switching assembly. The switching assembly comprises a switching assembly body, a first switching assembly, a second switching assembly, and a first button. The first and second switching assemblies are both connected to the first button. The switching assembly body is provided with a first water flow chamber and a second water flow chamber. Each of the first and second water flow chambers has a water inlet and two water outlets. The first switching assembly controls the opening and closing of the two water outlets of the first water flow chamber, while the second switching assembly controls the opening and closing of the two water outlets of the second water flow chamber. The water inlet assembly is used to control the water inlet of the switching assembly. The utility model uses the first button to control the first and second switching assemblies, thereby controlling the water outflow state of the first and second water flow chambers.

[0004] In the above solution, the switching structure and water channel arrangement are complicated and there are many parts, which results in the size of the faucet being too large and greatly restricting the appearance design of the faucet. Summary of the Invention

[0005] The invention discloses a switching water faucet, which aims to improve the problem that the existing water faucet has a complex structure and thus has limited external dimensions of the water faucet.

[0006] The present invention adopts the following scheme:

[0007] A switching water nozzle includes a shell, a valve stem arranged in the shell, and a button group for driving the valve stem to move axially. A water outlet is provided in the shell, and a plurality of water outlet holes are provided on the water outlet end of the valve stem. The valve stem is constructed to switch between a first position and a second position through the button group. When the valve stem is in the first position, water flows out from the water outlet channel of the water outlet, and a first form of water splash is produced; when the valve stem is in the second position, the water outlet channel is closed, and water flows out from the water outlet hole, and a second form of water splash is produced, so as to achieve two types of water splashes from one water outlet channel and one water outlet hole.

[0008] As a further improvement, the button group has a button, a base and an adapter, the button has a trigger part, a rotating part and a swinging part exposed from the shell, the rotating part is adaptively connected to the base, and the rotation is triggered by the trigger part, and the swinging part is linked to the rotating part so that the swinging part can swing forward or backward; the adapter is connected to the valve stem, and when the swinging part swings forward, the adapter drives the valve stem to move in a direction close to the water outlet part, and when the swinging part swings backward, the adapter drives the valve stem to move in a direction away from the water outlet part.

[0009] As a further improvement, an elastic member is provided between the adapter and the base, and the swinging part is obliquely inserted into the driving groove of the adapter. When the swinging part swings forward, it abuts against the driving groove and moves forward. At this time, the elastic member is in a compressed state; when the external water flow stops, the elastic member can drive the adapter to move backward.

[0010] As a further improvement, the trigger portion has a first surface and a second surface connected to the first surface, and the angle between the first surface and the second surface is an obtuse angle.

[0011] As a further improvement, a water channel is also installed in the shell, and the water channel has an inner pipe for the valve stem to move, and an outer pipe for water to flow through; the base is arranged on the outer periphery of the water channel, the adapter is movably arranged in the movable groove of the water channel, and the valve stem is inserted in the inner pipe of the water channel.

[0012] As a further improvement, the water channel is provided with a water inlet at one end and is connected to a diversion group at the other end. The diversion group includes a diversion plate, a beam component and a rectifying component.

[0013] As a further improvement, the first form of water splash is a single column of water, and the second form of water splash is multiple columnar water.

[0014] A switching water nozzle is also provided, comprising a shell, a valve stem arranged in the shell, and a button for driving the valve stem to move axially. The water outlet part in the shell is provided with a first water outlet part, and the valve stem is provided with a second water outlet part. The valve stem is constructed to switch between a first position and a second position by the button. When the valve stem is in the first position, a first channel is formed between the first water outlet part and the second water outlet part, and a first form of water splash is emitted at this time; when the valve stem is in the second position, a second channel is formed between the first water outlet part and the second water outlet part, and a second form of water splash is emitted at this time; so as to realize two types of water splashes from one water outlet channel and one water outlet hole; the second water outlet part is a water outlet groove recessed along the outer periphery of the valve stem, and the cross-section of the water outlet groove decreases step by step from the direction of water flow.

[0015] A pull-out faucet is also provided, comprising a faucet body and a switching water spout arranged on the faucet body, wherein the switching water spout is the switching water spout described above.

[0016] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0017] The switching faucet of the present application opens or closes the water outlet channel by moving the valve stem, thereby switching between different water splashes. When the water outlet channel is open, water flows out from the water outlet hole and the periphery of the valve stem, then converges into the water outlet channel to form a single column of water, and finally flows from the water outlet channel to the user end. When the water outlet channel is closed, water can only flow out from the water outlet hole of the valve stem, forming multiple columns of water (such as shower water, etc.), which are sprayed toward the user end. Compared with the prior art, there is no need to set up a variety of different water outlet holes on the same water outlet surface cover, nor is there a need to set up multiple water channels connected to various water outlet holes. In the present application, only one water channel and one water outlet hole are required to produce two types of water splashes. The water channel structure is simpler, which can save parts and reduce the volume, so that the appearance design of the faucet is not affected by the structural arrangement and is more diversified, meeting the user's pursuit of minimalist style.

[0049] Example

[0050] Combine Figures 1 to 10 This embodiment provides a switching water nozzle, including a shell 1, a valve stem 2 arranged in the shell 1, and a button group 3 for driving the valve stem 2 to move axially. A water outlet part 11 is provided in the shell 1, and a water outlet channel 111 is provided along the water outlet part 11. The water outlet part 11 can be integrally formed with the shell 1, or can be assembled on the shell 1. In this embodiment, the water outlet part 11 is connected to the shell 1 by a thread. There are several water outlet holes 21 on the water outlet end of the valve stem 2. The valve stem 2 is constructed to switch between a first position and a second position through the button group 3. When the valve stem 2 is in the first position, water flows out from the water outlet channel 111 of the water outlet part 11, and a first form of water splash is produced at this time; when the valve stem 2 is in the second position, the water outlet channel 111 is closed, and water flows out from the water outlet hole 21, and a second form of water splash is produced at this time. For example, a sealing ring is provided around the outer periphery of the valve stem 2, and the sealing ring moves with the valve stem 2. When the valve stem 2 moves to the second position, the sealing ring seals the valve stem 2 and the water outlet channel 111, thereby closing the water outlet channel 111. In this embodiment, the first form of water spray is preferably a single column of water, and the second form of water spray is preferably multiple columns of water.

[0051] It should be noted that, in this embodiment, the water outlet channel 111 is opened or closed by the movement of the valve stem 2, thereby switching different water splashes. When the water outlet channel 111 is opened, water flows out from the water outlet hole 21 and the side of the valve stem 2 and then converges into the water outlet channel 111 to form a single column of water, and finally flows from the water outlet channel 111 to the user end. When the water outlet channel 111 is closed, water can only flow out from the water outlet hole 21 of the valve stem 2, forming multiple columns of water (such as shower water, etc.), which are sprayed toward the user end. In this embodiment, only one water channel and one water outlet are required to produce two types of water splashes. Compared with the existing technology, its water channel structure is simpler, which can save parts and reduce the volume, so that the appearance design of the faucet is not affected by the structural volume, and can be more diversified, meeting the user's pursuit of minimalist style.

[0052] In another embodiment, the button assembly 3 includes a button 31, a base 32, and an adapter 33. The button 31 includes a trigger portion 311, a rotating portion 312, and a swinging portion 313, which are exposed from the housing 1. The trigger portion 311 includes a first surface 31A and a second surface 31B connected to the first surface 31A. The angle between the first surface 31A and the second surface 31B is obtuse. When the first surface 31A is pressed, the first surface 31A becomes horizontal, and the second surface 31B tilts up, making it easier for the user to press the second surface 31B. Similarly, when the second surface 31B is pressed, the second surface 31B becomes horizontal, and the first surface 31A tilts up. The rotating portion 312 is provided on both sides of the button 31 and includes an annular assembly hole with an opening along the periphery of the annular assembly hole. During assembly, the assembly hole is pressed into the rotating shaft 321 of the base 32 along the direction of the opening, so that the button 31 can be rotatably arranged on the base 32. The swing portion 313 is arranged to extend obliquely and is configured in conjunction with the rotating portion 312 . Pressing the trigger portion 311 drives the rotating portion 312 to rotate around the rotating shaft 321 , causing the swing portion 313 to swing forward or backward.

[0053] The base 32 is disposed within the housing 1 and has a relief groove 322 for the swing portion 313 to pass through. This allows the swing portion 313 to pass through the relief groove 322 and be tilted into the drive groove 331 of the adapter 33. The drive groove 331 has inclined surfaces on both sides, and the inclined directions of the inclined surfaces are adapted to the swing direction of the swing portion 313.

[0054] The adapter 33 is connected to the valve stem 2. The valve stem 2 is provided with a mounting slot 22 extending therethrough. A mounting portion 332 is provided on the adapter 33 corresponding to the mounting slot 22. The mounting portion 332 is inserted into the mounting slot 22, thereby interlocking the valve stem 2 and the adapter 33. When the swing portion 313 swings forward, the adapter 33 drives the valve stem 2 toward the water outlet 11. When the swing portion 313 swings backward, the adapter 33 drives the valve stem 2 away from the water outlet 11.

[0055] Furthermore, an elastic member 34 (preferably a spring) is disposed between the adapter 33 and the base 32. For example, the adapter 33 is provided with a boss 333 for receiving the elastic member 34, and the base 32 is provided with an abutment portion 323 opposite the boss 333. The swinging portion 313 is inserted obliquely into the drive slot 331 of the adapter 33. When the swinging portion 313 swings forward, the abutment portion 331 moves forward, thereby compressing the elastic member 34 and causing the adapter 33 to compress and move forward. When the external water flow stops, the elastic member 34 can drive the adapter 33 backward. It should be noted that in this embodiment, pressing the first surface 31A of the trigger portion 311 causes the swinging portion 313 to swing backward, at which point the valve stem 2 is in the first position; pressing the second surface 31B of the trigger portion 311 causes the swinging portion 313 to swing forward, at which point the valve stem 2 is in the second position. When the external water flow is on, pressing the second surface 31B causes the swinging portion 313 to swing forward. At this point, the elastic member 34 is compressed, the valve stem 2 moves forward, and water flows out of the water outlet 21. Under the action of the water pressure, the adapter 33 overcomes the elastic force of the elastic member 34 and remains in the second position. When the external water flow is off, the elastic force of the elastic member 34 causes the adapter 33 to swing the swinging portion 313 backward, causing the valve stem 2 to move backward. This ensures that the next time the water flow is turned on, the first type of water spray is produced: a single column of water with a large water output, making it convenient for users to clean the water daily.

[0056] In another embodiment of the present invention, based on the above embodiment, a water channel 12 is further installed within the housing 1. The water channel 12 includes an inner conduit 121 for movement of the valve stem 2 and an outer conduit for water flow. A base 32 is disposed on the outer periphery of the water channel 12. An adapter 33 is movably disposed within a movable groove 122 of the water channel 12. The valve stem 2 is inserted into the inner conduit 121 of the water channel 12 and connected to the adapter 33.

[0057] Preferably, one end of the water channel 12 is equipped with an inlet for connecting to an external water outlet (such as a faucet). The other end is connected to the diverter assembly 4, which includes a diverter plate 41, a flow-binding member 42, and a flow-rectifying member 43. The diverter plate 41 is provided with multiple water diversion holes 411. Water flows through the diverter holes 411 and enters the flow-binding member 42. The flow-binding member 42 has multiple ribs 421 along its inner circumference to reduce water flow noise. Water flows from the flow-binding member 42 into the flow-rectifying member 43. The water inlet cross-section of the flow-rectifying member 43 gradually decreases along the direction of water flow to increase the outlet pressure of the water.

[0058] Combine Figures 11 to 15Another embodiment of the present invention provides a switchable faucet. The portions not mentioned in this embodiment are identical to those of the above embodiment. Unlike the above embodiment, the water outlet member 11 within the housing 1 is provided with a first water outlet portion 112, and the valve stem 2 is provided with a second water outlet portion 23. The valve stem 2 is configured to switch between a first position and a second position via a button 31. When the valve stem 2 is in the first position, a first channel is formed between the first water outlet portion 112 and the second water outlet portion 23, producing a first type of water splash. When the valve stem 2 is in the second position, a second channel is formed between the first water outlet portion 112 and the second water outlet portion 23, producing a second type of water splash.

[0059] Preferably, the second water outlet portion 23 is provided with a water outlet groove 231 along the outer periphery of the valve stem 2, and the cross-section of the water outlet groove 231 decreases step by step in the direction of water flow. When the water outlet groove 231 is aligned with the first water outlet portion 112, that is, when the valve stem 2 is in the second position, water flows out from the second channel formed by each water outlet groove 231 and the first water outlet portion 112, and multiple columns of water are discharged at this time. It can be understood that each water outlet groove 231 cooperates with the first water outlet portion 112 to form multiple water outlet holes. When the water outlet groove 231 is misaligned with the first water outlet portion 112, that is, when the valve stem 2 is in the first position, water flows from the circumference of the valve stem 2 to the first water outlet channel 111, and a single column of water is discharged at this time.

[0060] Combine Figures 16 to 18 Another embodiment of the present invention provides a pull-out faucet, comprising a faucet body 5 and a switching water nozzle arranged on the faucet body 5, and the switching water nozzle is the switching water nozzle described in any of the above embodiments. The switching water nozzle is connected to the pull-out tube 6, and the user can pull the switching water nozzle out of the faucet body 5. The water spray can also be switched while holding the switching water nozzle, which is convenient for the user to use. Among them, the structure and working principle of the pull-out faucet are existing technologies and will not be repeated here. In addition, the volume of the switching water nozzle is reduced, which can make the switching water nozzle compatible with the bend part 51 on the faucet body 5. Usually, the diameter of the bend part 51 is small, and the small-volume switching water nozzle can be recovered and fixed in the inner diameter of the bend part 51, so that the appearance of the faucet body 5 is more integrated and neater.

[0061] The above are only preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention.
