Description

Technical Field

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

[0002] Ordinary faucets only have a single downward water flow function, which cannot meet users' needs for rinsing their mouths and washing their faces. Therefore, existing technology has developed many faucets with integrated mouthwash functions. These faucets can not only flow water downwards but also upwards. When the water flows downwards, it can be used for washing hands or collecting water; when the water flows upwards, it can be used directly for rinsing the mouth and washing the face. Furthermore, existing faucets with integrated mouthwash functions mainly fall into two categories: the first type has two water flow channels within the faucet body, with a switching component to achieve water flow switching; the second type has a water outlet module at the outlet end of the faucet body, using the rotation of the water outlet module to switch water flow. The first type of faucet has the following drawbacks: the faucet body is a large component, and directly machining the water flow channels internally would complicate the manufacturing process, increase manufacturing costs, and make it difficult to repair or replace if an internal malfunction occurs. The second type of faucet has a water outlet module with two water flow channels, which can be switched by simply engaging a switching connector inside the faucet body. Therefore, the internal structure of the second type of faucet is simpler and easier to manufacture. Furthermore, if the water circuit malfunctions, the water outlet module can be directly removed for repair or replacement. However, the second type of faucet also has the following drawbacks: when switching water flow, the entire water outlet module needs to rotate. Since the water outlet module is often not a single component, rotating the entire module can affect stability and cause loosening between parts. Also, because the entire water outlet module needs to rotate, there is no clearly visible operating part or handle, making the entire water outlet module easily mistaken for part of the faucet body, which can lead to users not knowing how to use it on first use. Summary of the Invention

[0003] This invention addresses the technical problems existing in the prior art by providing a water outlet module and faucet, which simplifies the internal structure of the faucet body and makes it easier for users to use.

[0004] The technical solution adopted by this invention to solve its technical problem is: a water outlet module for installation on the water outlet end of a faucet body, comprising:

[0005] The water outlet housing is provided with a first water outlet that allows water to flow upward and a second water outlet that allows water to flow downward;

[0006] The rotating core has a water flow channel;

[0007] The rotating core is rotatably installed inside the water outlet housing and is provided with a rotating operating part located outside the water outlet housing; the rotating core switches between multiple states by rotation, and the multiple states include at least a first state and a second state. In the first state, the water flow channel is connected to the first water outlet, and in the second state, the water flow channel is connected to the second water outlet.

[0008] Furthermore, the multiple states also include a third state, which is: the water flow channel is not connected to the first outlet and the second outlet.

[0009] Furthermore, the side wall of the rotating core is provided with a water inlet that connects to the water flow channel. The water flow channel is connected to the first water outlet or the second water outlet through the water inlet. The outer side of the rotating core is provided with a sealing gasket surrounding the water inlet, and the sealing gasket is in contact with the inner wall of the water outlet housing.

[0010] Furthermore, there are two water inlets, which are staggered in the axial and circumferential directions of the rotating core. The two water inlets are circumferentially connected to the first water outlet and the second water outlet, respectively. In the first state, one water inlet is connected to the first water outlet and the other water inlet is not connected to the second water outlet. In the second state, one water inlet is not connected to the first water outlet and the other water inlet is connected to the second water outlet.

[0011] Furthermore, a filter screen and / or water-saving plate are installed in the water flow channel of the rotating core at the position corresponding to one of the water inlets.

[0012] Furthermore, one end of the rotating core extends out of the water outlet housing, and the inlet of the water flow channel is located at the other end of the rotating core. It also includes a connector that is snapped into the rotating operating part, and the connector is provided with a gripper and a flat-section anti-rotation channel sequentially along one end of the rotating core towards the other. One end of the rotating core has a flat-section connecting post, and the tail end of the connecting post has a ball head. The connecting post is adapted to pass through the anti-rotation channel, and the ball head is held by the gripper.

[0013] Furthermore, it also includes a gear shifting structure, which includes a spring ball installed on the rotating operating part and a plurality of positioning grooves provided on the water outlet housing. The plurality of positioning grooves are distributed circumferentially along the water outlet housing. As the rotating core rotates, the spring ball switches and engages with the plurality of positioning grooves.

[0014] Furthermore, a limiting structure is fitted between the rotating core and the water outlet shell to limit the rotation angle of the rotating core; the limiting structure includes a limiting groove provided on the outer side of the rotating core along its circumference and a limiting boss provided on the inner wall of the water outlet shell, the limiting groove and the limiting boss slidingly fitted along the circumference of the rotating core.

[0015] The present invention also provides a faucet, including a faucet body having a water outlet channel, and further including a water outlet module as described above. The water outlet housing is installed at the water outlet end of the faucet body, and the water flow channel of the rotating core is connected to the water outlet channel.

[0016] Furthermore, the first and second water outlets of the water outlet housing are respectively located within the faucet body. The water outlet end of the faucet body is provided with a third water outlet that can outlet water upward and a fourth water outlet that can outlet water downward. The third water outlet is vertically connected to the first water outlet, and the second water outlet is vertically connected to the fourth water outlet. The water outlet channel is integrally formed with the faucet body, or the water outlet channel is formed in a connecting rod inserted into the faucet body.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The water outlet module of this invention includes the water outlet housing and the rotating core, which can be directly installed on the faucet body to achieve both upper and lower water outlet functions. Therefore, the water outlet module of this invention simplifies the internal structure of the faucet body, making it easier to manufacture. Furthermore, in case of water circuit malfunction, the water outlet module can be directly removed for repair or replacement. In particular, when switching water outlets, only the rotating core needs to be rotated, without rotating the entire water outlet module. Therefore, this invention improves the stability of the entire water outlet module, and the rotating core's operation provides a user guide, making it easier for first-time users to learn how to use it.

[0019] 2. The multiple states also include the third state, which enables the water outlet module of the present invention to also have the function of pausing water outlet.

[0020] 3. The number of water inlets is two, which allows the present invention to control the flow rate of the first water outlet and the second water outlet by controlling the flow rate of each water inlet, thereby avoiding the effect of the first water outlet and the second water outlet having the same flow rate, which would affect the use effect of the upper or lower water outlet.

[0021] 4. The rotating core and the rotating operating part are connected by the connector, so that the rotating core and the rotating operating part can be connected by hand without the aid of tools, making assembly and disassembly convenient.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments; however, the water outlet module and faucet of the present invention are not limited to the embodiments. Attached Figure Description

[0051] In this invention, the terms "first," "second," "third," and "fourth," etc., are used only to distinguish similar objects and are not necessarily used to describe a specific order or sequence, nor should they be construed as indicating or implying relative importance. The use of terms such as "upper," "lower," "front," and "rear" to indicate orientation or positional relationships is based on the orientation or positional relationships shown in the accompanying drawings and is only for the convenience of describing the invention, not to indicate or imply that the device referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the scope of protection of this invention. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0052] Furthermore, in the description of this application, unless otherwise stated, "multiple" means two or more. "And / or" describes the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone.

[0053] Please see Figures 1-8 As shown, a water outlet module of the present invention is used for installation at the water outlet end of a faucet body, comprising:

[0054] The water outlet housing 1 is provided with a first water outlet 11 that can discharge water upward and a second water outlet 12 that can discharge water downward;

[0055] Rotate the core 2, which has a water flow channel 23;

[0056] The rotating core 2 is rotatably mounted inside the water outlet housing 1, and a rotating operating part is provided outside the water outlet housing 1. The rotating core 2 switches between multiple states by rotation, including at least a first state and a second state. The first state is that the water flow channel 23 is connected to the first water outlet 11, but not connected to the second water outlet 12. The second state is that the water flow channel 23 is not connected to the first water outlet 11, but connected to the second water outlet 12. The connection includes both complete connection and partial connection, thus the rotating core 2 of the present invention can also realize flow regulation.

[0057] In this embodiment, the multiple states also include a third state, which is that the water flow channel is not connected to the first outlet 11 and the second outlet 12. Therefore, the water outlet module of the present invention also has the function of pausing water flow.

[0058] In this embodiment, the rotating core 2 has circular cross-sections and surrounding sidewalls. The sidewalls of the rotating core 2 are provided with a water inlet connecting to the water flow channel 23. The water flow channel 23 connects to the first outlet 11 or the second outlet 12 through the water inlet. A sealing gasket 3 is provided on the outer surface of the rotating core 2 surrounding the water inlet, and this sealing gasket 3 is in contact with the inner wall of the outlet housing 1. Specifically, an annular groove 28 is provided on the outer surface of the rotating core 2 around the water inlet to accommodate the sealing gasket 3.

[0059] In this embodiment, as Figure 2 , Figure 3 As shown, there are two water inlets, 21 and 22, which are staggered in the axial and circumferential directions of the rotating core 2. The two water inlets 21 and 22 are rotatably connected to the first outlet 11 and the second outlet 12, respectively, in the first state. In the second state, one water inlet 21 is connected to the first outlet 11, and the other water inlet 22 is not connected to the second outlet 12. In the third state, one water inlet 21 is not connected to the first outlet 11, and the other water inlet 22 is connected to the second outlet 12. The axes of the two water inlets 21 and 22 are perpendicular to each other. Therefore, the rotation angle of the rotating core 2 is less than or equal to 90°, making the rotation angle of the rotating core 2 smaller and the adjustment more convenient and faster. The first water outlet 11 and the second water outlet 12 are distributed one after the other, and the two water inlets 21 and 22 are also distributed one after the other. A partition is provided inside the water flow channel 23, dividing the channel into a front channel connected to the front water inlet 21 and a rear channel connected to the rear water inlet 22. A small hole 231 is opened in the partition to connect the front and rear channels. This results in a smaller flow rate when water exits from the front water inlet 21, making it convenient for washing the face or rinsing the mouth. The number of water inlets is not limited to two. In other embodiments, the number of water inlets is one. In this case, the first state is that the water inlet is connected to the first water outlet, and the second state is that the water inlet is connected to the second water outlet.

[0060] In this embodiment, a filter screen 8 and / or a water-saving plate 7 are installed inside the water flow channel 23 of the rotating core 2 at the water inlet (i.e., one of the water inlets 21) that cooperates with the first water outlet 11. Specifically, the rotating core 2 of the present invention simultaneously installs the filter screen 8 and the water-saving plate 7, with the filter screen 8 located outside the water-saving plate 7. The filter screen 8 can filter impurities, making the water cleaner when rinsing or washing the face. The water-saving plate 7 can reduce the flow rate, making the flow rate of water from the first water outlet 11 smaller, thereby reducing splashing and making it more suitable for rinsing or washing the face. To facilitate the installation of the filter screen 8 and the water-saving plate 7, an installation opening 24 is provided on the side wall of the rotating core 2, such as... Figure 3As shown, after the filter screen 8 and the water-saving plate 7 are sequentially inserted into the water flow channel 23 of the rotating core 2 through the installation port 24, the installation port 24 is sealed by a plug 9.

[0061] In this embodiment, one axial end of the rotating core 2 extends out of the water outlet housing 1 and is connected to the rotating operating part. The water inlet of the water flow channel 23 is located at the other axial end of the rotating core 2. The rotating operating part is specifically a knob 4, but is not limited to this. In other embodiments, the rotating operating part is a handle, etc.

[0062] In this embodiment, the water outlet module of the present invention further includes a connector 5, which is snapped into the rotating operating part (i.e., the knob 4). The connector 5 is provided with a gripper 51 and a flat-section anti-rotation channel 52 sequentially along one end of the rotating core 2 towards the other end. Figure 7 As shown; one end of the rotating core 2 along its axial direction is provided with a connecting post 25 with a flat cross-section, and the tail end of the connecting post 25 is provided with a ball head 26, as shown. Figure 2 , Figure 3 As shown, the connecting post 25 is adapted to pass through the anti-rotation channel 52, and the ball head 26 is held by the gripper 51. The gripper 51 is approximately C-shaped, and after holding the ball head 26, it can prevent the connecting member 5 from disengaging from the rotating core 2. The cross-sections of the connecting post 25 and the anti-rotation channel 52 are square, but not limited to this; the connecting post 25 and the anti-rotation channel 52 are adapted to each other to restrict the relative rotation of the connecting member 5 and the rotating core 2. Figure 6 As shown, the knob 4 has multiple locking posts 41 inside, and the tail of each locking post 41 branches to form multiple elastic buckles. The connector 5 has multiple locking holes 53 that correspond one-to-one with the locking posts 41 (e.g., ...). Figure 7 As shown, the locking pin 41 and the locking hole 53 are connected by a snap-fit.

[0063] In this embodiment, the water outlet module of the present invention also includes a gear shift structure, which provides a tactile feedback during operation and can also play a certain positioning role for the rotating core 2. The gear shift structure specifically includes components installed on the rotating operating part (i.e., knob 4, such as...) Figure 6 As shown, the water outlet housing 1 has a spring ball 6 in a cavity 42 and a plurality of positioning grooves 13 located on the end face of the water outlet housing 1 near the knob 4, and distributed around the circumference of the water outlet housing 1. The plurality of positioning grooves 13 correspond one-to-one with the various states. As the rotating core 2 rotates, the spring ball 6 switches and engages with the plurality of positioning grooves 13.

[0064] In this embodiment, a limiting structure is used between the rotating core 2 and the water outlet housing 1 to limit the rotation angle of the rotating core 2. Specifically, the limiting structure includes a limiting groove 27 (e.g., a groove 27 is provided circumferentially on the outer surface of the rotating core 2). Figure 2 (as shown) and the limiting boss 14 (as shown) provided on the inner wall of the water outlet shell 1 Figure 5 As shown, the limiting groove 27 and the limiting boss 14 slide together along the circumference of the rotating core 2.

[0065] This invention provides a water outlet module applicable to faucets, enabling them to perform functions such as top water outlet, bottom water outlet, and paused water flow. Specifically, the water outlet module can be directly installed on the faucet body. This water outlet module simplifies the internal structure of the faucet body, making it easier to manufacture. Furthermore, in case of water circuit malfunction, the water outlet module can be directly removed for repair or replacement. In particular, when switching water flow, only the knob 4 needs to be rotated to rotate the rotating core 2, without needing to rotate the entire water outlet module. Therefore, this invention improves the stability of the entire water outlet module, and the rotating operation part of the core 2 (i.e., the knob 4) provides a usage prompt, making it easier for first-time users to operate.

[0066] The working principle of a water outlet module of the present invention is described below.

[0067] Please see Figures 9-27 As shown, a faucet of the present invention includes a faucet body 40, which has a water outlet channel; it also includes a water outlet module as described above, wherein the water outlet housing 1 is installed at the water outlet end of the faucet body 40, and the water flow channel 23 of the rotating core 2 is connected to the water outlet channel.

[0068] In this embodiment, the first water outlet 11 and the second water outlet 12 of the water outlet housing 1 are respectively located inside the faucet body 40. The water outlet end of the faucet body 40 is provided with a third water outlet 401 that can discharge water upward and a fourth water outlet 402 that can discharge water downward. The third water outlet 401 is vertically connected to the first water outlet 11, and the second water outlet 12 is vertically connected to the fourth water outlet 402. Specifically, the first water outlet 11 and the third water outlet 401 are sealed and connected by an annular rubber gasket 10: the two ends of the annular rubber gasket 10 are respectively fitted onto the third water outlet 401 and the first water outlet 11, and a mesh 20 is provided between the annular rubber gasket 10 and the first water outlet 11; the inner hole of the annular rubber gasket 10 is an oblique hole that slopes towards the front of the faucet body 40, so that when water is discharged from the third water outlet 401, the water flow is tilted forward and output upward. A connector 60 is used to achieve a sealed connection between the second water outlet 12 and the fourth water outlet 402: the upper end of the connector 60 is fitted into the second water outlet 12, and the lower end of the connector 60 is threaded into the fourth water outlet 402. In other embodiments, the first water outlet 11 and the second water outlet 12 of the water outlet housing 1 are located outside the faucet body 40, so that the first water outlet 11 and the second water outlet 12 can directly discharge water.

[0069] In this embodiment, the water outlet channel is formed within a connecting rod 30 inserted into the faucet body 40. Therefore, one end of the connecting rod 30 is sealed and inserted into the inlet of the water flow channel 23 of the rotating core 2, and another end of the connecting rod 30 is screwed into the water outlet housing 1. The other end of the connecting rod 30 is connected to the outlet of the valve core 70 provided within the faucet body 40. The valve core 70 can be a common on / off valve core, a common mixing valve core, or a thermostatic valve core. In other embodiments, the water outlet channel is integrally formed with the faucet body 40.

[0070] In this embodiment, an aerator 50 is installed inside the fourth water outlet 402. Therefore, when water is discharged from the fourth water outlet 402, it can output bubble water downwards.

[0071] A faucet according to the present invention has two water outlet states and a paused water outlet state when its valve core 70 is opened. The first water outlet state is the bottom water outlet state, such as... Figures 11-13As shown, at this time, the water inlet 21 of the rotating core 2 at the front is not connected to the first water outlet 11 of the water outlet housing 1, while the water inlet 22 of the rotating core 2 at the rear is vertically connected to the second water outlet 12 of the water outlet housing 1. Water flows from the connecting rod 30 into the water flow channel 23 of the rotating core 2, and sequentially passes through the water inlet 22 of the rotating core 2 at the rear and the second water outlet 12 of the water outlet housing 1 to the fourth water outlet 402 of the faucet body 40, finally outputting bubble water downwards from the fourth water outlet 402. The second water outlet state is the top water outlet state, as shown... Figures 14-16 As shown, at this time, the water inlet 21 of the rotating core 2 at the front is connected vertically to the first water outlet 11 of the water outlet housing 1, while the water inlet 22 of the rotating core 2 at the rear is not connected to the second water outlet 12 of the water outlet housing 1. Water flows from the connecting rod 30 into the water flow channel 23 of the rotating core 2, and flows sequentially through the water inlet 21 of the rotating core 2 at the front and the first water outlet 11 of the water outlet housing 1 to the third water outlet 401 of the faucet body 40, finally outputting mouthwash upward from the third water outlet 401. The paused water output state is as follows: the water inlet 21 of the rotating core 2 at the front is not connected to the first water outlet 11 of the water outlet housing 1, and the water inlet 22 of the rotating core 2 at the rear is not connected to the second water outlet 12 of the water outlet housing 1. Therefore, no water flows from the third water outlet 401 or the fourth water outlet 402 of the faucet body 40. The three states can be switched by rotating the knob 4, which drives the rotating core 2 to rotate. Furthermore, in both water output states, the flow rate can be adjusted by fine-tuning the knob 4.

[0072] The changing states of the connection between the rotating core 2 at the front water inlet 21 and the first water outlet 11 of the water outlet housing 1, and between the rotating core 2 at the rear water inlet 22 and the second water outlet 12 of the water outlet housing 1, are as follows: Figures 18-27 As shown: The initial state is the fully open aerated water state. At this time, the water inlet 21 of the rotating core 2 is completely offset from the first water outlet 11 of the water outlet housing 1, as shown. Figure 18 As shown, the water inlet 22 of the rotating core 2 corresponds vertically to the second water outlet 12 of the water outlet housing 1, as follows: Figure 19 As shown; when knob 4 drives the rotating core 2 to rotate clockwise by a small angle, the water inlet 21 of the rotating core 2 at the front remains completely offset from the first water outlet 11 of the water outlet housing 1, as shown. Figure 20 As shown, the water inlet 22 of the rotating core 2 is partially offset from the second water outlet 12 of the water outlet housing 1, as follows: Figure 21 As shown, this achieves bubble water flow regulation; when knob 4 continues to drive the rotating core 2 to rotate clockwise by a small angle, the water inlet 21 of the rotating core 2 at the front remains completely offset from the first water outlet 11 of the water outlet housing 1, as shown. Figure 22As shown, the water inlet 22 of the rotating core 2 is completely offset from the second water outlet 12 of the water outlet housing 1, as... Figure 22 As shown, this achieves the function of pausing water flow; when the knob 4 continues to drive the rotating core 2 to rotate clockwise by a small angle, the water inlet 21 of the rotating core 2 at the front is partially misaligned with the first water outlet 11 of the water outlet housing 1, as shown. Figure 23 As shown, this achieves the mouthwash flow regulation function. The water inlet 22 of the rotating core 2 is completely offset from the second water outlet 12 of the water outlet housing 1, as shown. Figure 25 As shown; when knob 4 continues to drive the rotating core 2 to rotate clockwise by a small angle, the water inlet 21 of the rotating core 2 at the front is vertically aligned with the first water outlet 11 of the water outlet housing 1, as shown. Figure 26 As shown, this achieves the mouthwash fully open state, with the water inlet 22 of the rotating core 2 completely offset from the second water outlet 12 of the water outlet housing 1, as... Figure 27 As shown. When knob 4 is rotated in the opposite direction, the invention sequentially goes through the mouthwash full-on state, mouthwash flow adjustment state, paused water flow state, sparkling water flow adjustment state, and finally returns to the sparkling water full-on state.
