Technical Field

[0001] This application relates to the field of faucet technology, and more particularly to a pull-out faucet and a pull-out tap. Background Technology

[0002] A pull-out faucet is a type of faucet where the nozzle can be pulled out to allow for water flow at various angles. Currently, pull-out faucets typically include a water path switching mechanism and a button on the outer wall.

The water channel assembly and the housing are movable relative to the central tube assembly, so that the water channel assembly can be switched between a first position that connects the water inlet channel and the first flow path, and a second position that connects the water inlet channel and the second flow path.

[0006] In some embodiments, the transition water channel is funnel-shaped, with the narrow end of the transition water channel serving as the inlet and the wide end serving as the outlet; the narrow end of the transition water channel is fitted inside the central tube assembly and sealed by a sealing structure.

[0007] In some embodiments, the outer wall of the central tube assembly is provided with a first water passage hole communicating with the water inlet channel. The first water passage hole can communicate with the first flow path when the water channel assembly moves to the first position, and communicate with the second flow path when the water channel assembly moves to the second position.

[0008] In some embodiments, seals are provided on both sides of the first water passage in the direction of movement of the waterway assembly; When the waterway assembly moves to the first position, one of the two seals seals the first water passage and the second flow path, and when the waterway assembly moves to the second position, the other of the two seals seals the first water passage and the first flow path.

[0009] In some embodiments, the water channel assembly includes a first water channel, a second water channel, and an outer water channel. The first water channel and the second water channel are fixedly connected and coaxially arranged with the central tube assembly. The outer water channel is sleeved around the first water channel and the second water channel. The gap between the first waterway and the outer waterway, and the gap between the second waterway and the outer waterway, are connected to form the first flow path; the first waterway is provided with a first waterway opening that is connected to the first flow path, and the first waterway opening is used to connect with the water inlet channel when the waterway assembly moves to the first position; the second waterway is provided with a second waterway opening, and the second waterway opening is connected to the first flow path and the first water splash outlet respectively.

[0010] In some embodiments, the water channel assembly includes a water outlet disposed within the housing and engaging with the end of the second water channel remote from the first water channel. The water outlet is provided with a first water outlet path and a second water outlet path, and the first water splash outlet and the second water splash outlet are both located on the water outlet. The first water outlet path is connected to the first water splash outlet and the first flow path, and the second water outlet path is connected to the second water splash outlet and the second flow path.

[0011] In some embodiments, a fastener is provided on the outside of the water outlet, the fastener being disposed inside the housing and connected to the housing.

[0012] In some embodiments, the inner diameter of the first waterway and the inner diameter of the second waterway are the same, and the outer diameter of the first waterway and the outer diameter of the second waterway are the same, so that the water pressure in the waterway remains balanced when the waterway assembly switches back and forth between the first position and the second position.

[0013] In some embodiments, the gap between the water channel assembly and the central pipe assembly forms the second flow path, and the outer wall of the central pipe assembly is provided with a second water passage hole that communicates with the transition flow path and the second flow path respectively. And / or, the central tube assembly includes a central plug and a water inlet connector sleeved on the central plug, the water inlet being located at the water inlet connector, and the water inlet channel being located at the central plug; And / or, the pull-out head further includes an elastic reset structure, which is disposed between the central tube assembly and the water channel assembly, so that the water channel assembly can move under the elastic force of the elastic reset structure and reset from the second position to the first position.

[0014] Secondly, this application also provides a pull-out faucet, including a faucet body and a pull-out head, wherein the pull-out head is connected to the faucet body.

[0015] The beneficial effects of this utility model are: This utility model provides a pull-out head and a pull-out faucet. The pull-out head includes a housing, a water channel assembly, a central tube assembly, and a connecting water channel. When it is necessary to switch water channels to achieve different water spray patterns, simply apply an external force to the housing, causing the housing and water channel assembly to move relative to the central tube assembly. This moves the water channel assembly to a first position where the inlet channel and the first flow path are connected. At this time, the inlet, the inlet channel, the first flow path, and the first water spray outlet are connected to achieve the first water spray pattern. When the water channel assembly is moved to a second position where the inlet channel and the second flow path are connected, the inlet, the inlet channel, the second flow path, the connecting flow path, and the second water spray outlet are connected to achieve the second water spray pattern. The entire operation is simple and does not require buttons on the pull-out head to switch water spray patterns, thus avoiding problems such as difficulty in cleaning and poor appearance caused by buttons. Meanwhile, in this embodiment of the present invention, the pull-out head has a transfer water channel inside the central tube assembly. When the second water splash pattern is produced, the water flows out from the second flow path and then enters the transfer flow path before flowing out from the second water splash outlet. That is, the water flows out from the second flow path and then enters the transfer water channel to reduce the diameter of the water path. This can effectively reduce the pressure surface in the direction of water flow, so that the switching force required by the user when switching between different water splash patterns is smaller, thus saving effort and effectively improving the user experience.

[0019] In the embodiments of this application, the terms "first," "second," "third," "fourth," "fifth," and "sixth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," "third," "fourth," "fifth," and "sixth" may explicitly or implicitly include one or more of that feature.

[0020] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0021] Reference Figures 1 to 5 As shown, this embodiment provides a pull-out head including a housing 100, a water channel assembly 200, a central tube assembly 300, and a connecting water channel 400.

[0022] The water channel assembly 200 is housed within the outer casing 100. The water channel assembly 200 has a first flow path 210, a second flow path 220, a first water splash outlet 230 communicating with the first flow path 210, and a second water splash outlet 240 communicating with the second flow path 220.

[0023] The central pipe assembly 300 is disposed within the water channel assembly 200 and has an inlet 310 and an inlet channel 320 connected to the inlet 310; the transfer water channel 400 is disposed within the central pipe assembly 300 and has a transfer flow path 410 connected to the second flow path 220 and the second water splash outlet 240 respectively.

[0024] The water channel assembly 200 and the housing 100 are movable relative to the central tube assembly 300 so that the water channel assembly 200 can be switched between a first position that connects the water inlet channel 320 and the first flow path 210, and a second position that connects the water inlet channel 320 and the second flow path 220.

[0025] In practice, the outer casing 100 can be a cylindrical structure made of alloy, plastic, or stainless steel. The water channel assembly 200 is disposed inside the outer casing 100 and fixed relative to it, which can be an interference fit, a snap-fit ​​connection, or a threaded connection.

[0026] The water channel assembly 200 has a first flow path 210 and a second flow path 220. The first flow path 210 is connected to a first water splash outlet 230, allowing water to flow within the first flow path 210 and then exit through the first water splash outlet 230 in a first water splash pattern. For example, the first water splash outlet 230 can be a soft water outlet or a sparkling water outlet, in which case water flowing within the first flow path 210 can exit through the first water splash outlet 230 in a soft water or sparkling water pattern. The second flow path 220 is connected to a second water splash outlet 240, allowing water to flow within the second flow path 220 and then exit through the second water splash outlet 240 in a second water splash pattern. For example, the second water splash outlet 240 can be a blade water outlet or a shower water outlet, in which case water flowing within the second flow path 220 can exit through the second water splash outlet 240 in a blade water or shower water pattern, thus achieving different water splash patterns to meet different user needs.

[0027] Specifically, the central pipe assembly 300 is located within the water channel assembly 200, and the two can move relative to each other. For example, the central pipe assembly 300 can move while the water channel assembly 200 remains stationary, or the water channel assembly 200 can move while the central pipe assembly 300 remains stationary.

[0028] The central tube assembly 300 is provided with a water inlet 310 and a water inlet channel 320 communicating with the water inlet 310. When the water channel assembly 200 and the outer casing 100 move together relative to the central tube to such a position... Figure 3 In the first position shown, the water inlet channel 320 is connected to the first flow path 210 but closed to the second flow path 220. Water entering the water inlet channel 320 through the inlet 310 flows to the first flow path 210 and is finally discharged through the first water splash outlet 230, achieving the first water splash pattern. The specific flow path of the water in the first water splash pattern can be found in [reference needed]. Figure 3 As shown by the dashed arrow in the diagram. When the water channel assembly 200 and the housing 100 move together relative to the central pipe to... Figure 4 In the second position shown, the inlet channel 320 is connected to the second flow path 220 but closed to the first flow path 210. Water entering the inlet channel 320 through the inlet 310 flows into the second flow path 220, then into the transition flow path 410, and finally exits through the second splash outlet 240, achieving the second splash water discharge operation. The specific flow path of the second splash water can be found in [reference needed]. Figure 4 The dashed arrow in the image is shown.

[0029] In other words, when it is necessary to switch between different water spray modes, the pull-out head of this embodiment only needs to apply an external force to the outer shell 100 or the central tube assembly 300 to change the different positions of the water channel assembly 200. This operation is simple and quick, and there is no need to set a button on the pull-out head to switch water spray modes. Therefore, it can avoid problems such as difficulty in cleaning and poor appearance caused by setting a button.

[0030] Furthermore, in this embodiment, a transition water channel 400 is provided inside the central pipe assembly 300. Since the transition water channel 400 is provided inside the central pipe assembly 300, and the water channel assembly 200 is sleeved outside the central pipe assembly 300, when water is discharged in the second splash pattern, the water flowing out through the inlet channel 320 flows into the second flow path 220 and then enters the transition flow path 410 to achieve water channel diameter reduction. This can effectively reduce the pressure surface in the water flow direction, so that the switching force required by the user when switching between different splash patterns is smaller, thus saving effort and effectively improving the user experience.

[0031] In other words, when the second water outlet 240 is small, back pressure is easily formed in the second flow path 220. Under the action of back pressure, the pressure-bearing surface generates a force in the direction of water flow, which is also the resistance when the water channel component 200 switches from the second position to the first position. Therefore, in this embodiment, the pressure-bearing surface is reduced by setting the transition water channel 400 to reduce this resistance, so that the user can switch the water outlet mode with less effort.

[0032] For example, the direction of movement of the waterway assembly 200 can be as follows: Figure 3 and Figure 4 The vertical direction shown refers specifically to the direction in which the water channel assembly 200 moves from the first position to the second position, which is from top to bottom, and the direction in which the water channel assembly 200 moves from the second position to the first position, which is from bottom to top. In this embodiment, the water channel assembly 200 and the outer shell 100 are specifically configured as moving parts, while the central tube assembly 300 remains stationary as a fixed part, which facilitates the application of force.

[0033] The pull-out head in this embodiment includes a housing 100, a water channel assembly 200, a central tube assembly 300, and a transition water channel 400. When it is necessary to switch water channels to achieve different water spray patterns, simply apply external force to the housing 100, i.e., the user can operate it with one hand, so that the housing 100 and the water channel assembly 200 move relative to the central tube assembly 300. This moves the water channel assembly 200 to a first position that connects the water inlet channel 320 and the first flow path 210. At this time, the water inlet 310, the water inlet channel 320, the first flow path 210, and the first water spray outlet 230 are connected to achieve water spray in the first water spray pattern. When the water channel assembly 200 is moved to the second position that connects the water inlet channel 320 with the second flow path 220, the water inlet 310, the water inlet channel 320, the second flow path 220, the transition flow path 410, and the second water splash outlet 240 are connected to achieve water output in the second water splash pattern. The entire operation is simple and does not require setting a button on the pull-out head to switch water splashes. Therefore, it can avoid problems such as difficulty in cleaning and poor appearance caused by setting a button. Meanwhile, in this embodiment, the pull-out head has a transition water channel 400 inside the central tube assembly 300. When the second water splash pattern is produced, the water flows out of the second flow path 220 and then enters the transition flow path 410 before flowing out of the second water splash outlet 240. That is, the water flows out of the second flow path 220 and then enters the transition water channel 400 to reduce the diameter of the water path. This can effectively reduce the pressure surface in the direction of water flow, so that the switching force required by the user when switching between different water splash patterns is smaller, thus saving effort and effectively improving the user experience.

[0034] Reference Figure 3 and Figure 4 As shown, in some embodiments, the transition water channel 400 is funnel-shaped, with the narrow end of the transition water channel 400 serving as the inlet and the wide end serving as the outlet. The narrow end of the transition water channel 400 is fitted inside the central pipe assembly 300 and sealed by the sealing structure 420 to achieve a sealed fit. Since the transition water channel 400 is funnel-shaped, it facilitates easy switching and saves effort. Water entering the transition water channel 400 can flow within the gradually increasing inner diameter of the transition water channel 400, thereby increasing the flow rate and preventing poor water output efficiency.

[0035] For example, the sealing structure 420 can be a sealing ring or sealing foam.

[0036] Reference Figure 3 and Figure 4 As shown, in some embodiments, the outer wall of the central tube assembly 300 is provided with a first water passage 330 that communicates with the water inlet channel 320. The first water passage 330 can communicate with the first flow path 210 when the water channel assembly 200 moves to the first position, and communicate with the second flow path 220 when the water channel assembly 200 moves to the second position.

[0037] In specific implementation, when the waterway assembly 200 moves relative to the central pipe assembly 300 to such a position... Figure 3 In the first position shown, the first water passage 330 is connected to the first flow path 210 and closed to the second flow path 220. Therefore, the water entering the water inlet channel 320 through the inlet 310 flows through the first water passage 330 to the first flow path 210 and is finally discharged through the first water splash outlet 230, realizing the water discharge operation in the first water splash form. The specific flow path of the water in the first water splash form can be referred to Figure 3 The dashed arrow in the image is shown.

[0038] When the waterway assembly 200 moves relative to the central pipe assembly 300 to such a position Figure 4 In the second position shown, the first water passage 330 is connected to the second flow path 220 and closed to the first flow path 210. Thus, water entering the water inlet channel 320 through the inlet 310 flows through the first water passage 330 to the second flow path 220, then to the transition flow path 410, and finally exits through the second water splash outlet 240, achieving the second water splash pattern water discharge operation. The specific flow path of the water in the second water splash pattern can be found in [reference needed]. Figure 4 The dashed arrow in the image is shown.

[0039] For example, the first water passage 330 can be a straight groove hole provided on the outer wall of the central tube assembly 300, or it can be an annular hole or a cross-shaped hole.

[0040] Reference Figure 3 and Figure 4 As shown, in some embodiments, seals 340 are provided on both sides of the first water passage 330 along the moving direction of the waterway assembly 200.

[0041] When the water channel assembly 200 moves to the first position, one of the two seals 340 seals the first water passage 330 and the second flow path 220. When the water channel assembly 200 moves to the second position, the other of the two seals 340 seals the first water passage 330 and the first flow path 210.

[0042] That is, along Figure 3 In the vertical direction shown, sealing elements 340 are provided above and below the first water passage 330.

[0043] When the waterway assembly 200 moves relative to the central pipe assembly 300 to such a position Figure 3 In the first position shown, the first water passage 330 is connected to the first flow path 210 and is sealed to the second flow path 220 by the seal 340 below the first water passage 330.

[0044] When the waterway assembly 200 moves relative to the central pipe assembly 300 to such a position Figure 4 In the second position shown, the first water passage 330 is connected to the second flow path 220 and is sealed to the first flow path 210 by the seal 340 above the first water passage 330.

[0045] In practice, the central tube assembly 300 is provided with an annular groove at the position corresponding to the seal 340. At this time, the seal 340 can be accommodated in the corresponding annular groove and partially protrude out of the annular groove to abut against the water channel assembly 200 for sealing.

[0046] For example, the seal 340 can be a sealing ring or sealing foam.

[0047] Reference Figure 3 and Figure 4 As shown, in some embodiments, the water channel assembly 200 includes a first water channel 250, a second water channel 260, and an outer water channel 270. The first water channel 250 and the second water channel 260 are fixedly connected and coaxially arranged with the central tube assembly 300, and the outer water channel 270 is sleeved around the first water channel 250 and the second water channel 260.

[0048] The gaps between the first waterway 250 and the outer waterway 270, and between the second waterway 260 and the outer waterway 270, are connected to form the first flow path 210. The first waterway 250 is provided with a first waterway opening that communicates with the first flow path 210. The first waterway opening is used to communicate with the water inlet channel 320 when the waterway assembly 200 moves to the first position. The second waterway 260 is provided with a second waterway opening that communicates with both the first flow path 210 and the first water splash outlet 230.

[0049] In specific implementation, when the waterway component 200 moves to such a position... Figure 3 In the first position shown, water entering the inlet channel 320 through the inlet 310 flows through the first water passage 330 to the gap between the first water channel 250 and the central pipe assembly 300, and then flows into the first water channel opening. From there, it flows into the first flow path 210, which connects the gap between the first water channel 250 and the outer water channel 270, and the gap between the second water channel 260 and the outer water channel 270. Finally, it flows through the second water channel opening to the first water splash outlet 230, thus achieving the first water splash pattern water discharge operation. The specific flow path of the first water splash pattern water can be found in [reference needed]. Figure 3 The dashed arrow in the image is shown.

[0050] Reference Figure 3 , Figure 4 and Figure 5As shown, in some embodiments, the water channel assembly 200 includes a water outlet 280 disposed within the housing 100 and engaging with the end of the second water channel 260 that is away from the first water channel 250.

[0051] The water outlet 280 is provided with a first water outlet flow path 281 and a second water outlet flow path 282, and the first water splash outlet 230 and the second water splash outlet 240 are both provided on the water outlet 280. The first water outlet flow path 281 is connected to the first water splash outlet 230 and the first flow path 210 respectively, and the second water outlet flow path 282 is connected to the second water splash outlet 240 and the second flow path 220 respectively.

[0052] In other words, when the waterway assembly 200 moves relative to the central pipe assembly 300 to such a position... Figure 3 In the first position shown, the first water passage 330 is connected to the first flow path 210 and closed to the second flow path 220. Therefore, the water entering the water inlet channel 320 through the inlet 310 flows through the first water passage 330 to the first flow path 210 and then into the first water outlet flow path 281, finally being discharged through the first water splash outlet 230, realizing the water discharge operation in the first water splash form. The specific flow path of the water in the first water splash form can be referred to Figure 3 The dashed arrow in the image is shown.

[0053] When the waterway assembly 200 moves relative to the central pipe assembly 300 to such a position Figure 4 In the second position shown, the first water passage 330 is connected to the second flow path 220 and closed to the first flow path 210. Thus, water entering the inlet channel 320 through the inlet 310 flows through the first water passage 330 to the second flow path 220, then to the transition flow path 410, and finally to the second outlet flow path 282, ultimately exiting through the second water splash outlet 240, achieving the second water splash pattern water discharge operation. The specific flow path of the water in the second water splash pattern can be found in [reference needed]. Figure 4 The dashed arrow in the image is shown.

[0054] For example, the water outlet 280 can be a water outlet 280 or a water outlet connector 620. The first water outlet 230 is, for example, a soft water outlet. In this case, there can be multiple soft water outlets arranged in an array. The second water outlet 240 is, for example, a blade water outlet. In this case, there can be multiple blade water outlets arranged in an array. All the first water outlets 230 are arranged around the second water outlet 240 to achieve a reasonable distribution of their positions.

[0055] Reference Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, a fastener 290 is provided outside the water outlet 280, and the fastener 290 is located inside the housing 100 and connected to the housing 100.

[0056] Specifically, the fastener 290 can be a locking nut, and the inner wall of the outer casing 100 is provided with threads. The locking nut engages with the threads and presses the water outlet onto the second water channel 260. At the same time, the first water channel 250, the second water channel 260, and the outer water channel 270 are clamped together onto the outer casing 100, so that the first water channel 250, the second water channel 260, the outer water channel 270, the water outlet 280, and the outer casing 100 form a relatively fixed whole, and can move relative to the central tube assembly 300 under the drive of the outer casing 100, so as to realize the free switching between the first position and the second position.

[0057] Alternatively, fastener 290 can be a fastening pin or a clip, etc.

[0058] In some embodiments, the inner diameter of the first waterway 250 is the same as the inner diameter of the second waterway 260, and the outer diameter of the first waterway 250 is the same as the outer diameter of the second waterway 260, so that the water pressure in the waterway remains balanced when the waterway assembly 200 switches back and forth between the first position and the second position.

[0059] This configuration ensures that the areas of the corresponding flow paths formed between the first water channel 250, the second water channel 260, and the central pipe assembly 300 are the same, so that the water pressure in the corresponding flow paths is relatively balanced when switching water flow to different water splash patterns, thereby reducing the switching resistance.

[0060] Reference Figure 4 As shown, in some embodiments, the gap between the water channel assembly 200 and the central tube assembly 300 forms a second flow path 220, and the outer wall of the central tube assembly 300 is provided with a second water passage 350 that communicates with the transition flow path 410 and the second flow path 220 respectively.

[0061] When the waterway assembly 200 moves relative to the central pipe assembly 300 to such a position Figure 4 In the second position shown, the first water passage 330 is connected to the second flow path 220 and closed to the first flow path 210. Thus, water entering the inlet channel 320 through the inlet 310 flows through the first water passage 330 to the second flow path 220, then through the second water passage 350 to the transition flow path 410, and finally exits through the second water outlet 240, achieving the second water splash pattern water discharge operation. The specific flow path of the water in the second water splash pattern can be found in [reference needed]. Figure 4 The dashed arrow in the image is shown.

[0062] Reference Figures 3 to 5 As shown, in some embodiments, the central tube assembly 300 includes a central plug 360 and a water inlet connector 370 sleeved on the central plug 360, a water inlet 310 is provided on the water inlet connector 370, and a water inlet channel 320 is provided on the central plug 360.

[0063] In practice, the inlet connector 370 and the center plug 360 can be connected by threads to form a relatively fixed whole, so as to form a relatively movable connection with the water channel assembly 200.

[0064] Specifically, when the waterway assembly 200 moves relative to the central pipe assembly 300 to such a position... Figure 3 In the first position shown, the first water passage 330 is connected to the first flow path 210 and closed to the second flow path 220. Therefore, the water entering the water inlet channel 320 of the center plug 360 through the water inlet 310 of the water inlet connector 370 flows through the first water passage 330 to the first flow path 210 and then into the first water outlet flow path 281, finally being discharged through the first water splash outlet 230, realizing the water discharge operation in the first water splash form. The specific water flow path in the first water splash form can be referred to Figure 3 The dashed arrow in the image is shown.

[0065] When the waterway assembly 200 moves relative to the central pipe assembly 300 to such a position Figure 4 In the second position shown, the first water passage 330 is connected to the second flow path 220 and closed to the first flow path 210. Thus, water entering the water inlet channel 320 of the center plug 360 through the inlet 310 of the inlet connector 370 flows through the first water passage 330 to the second flow path 220, then to the transition flow path 410, and finally to the second outlet flow path 282, ultimately exiting through the second water splash outlet 240, achieving the second water splash pattern water discharge operation. The specific flow path of the second water splash pattern water can be found in [reference needed]. Figure 4 The dashed arrow in the image is shown.

[0066] Reference Figures 3 to 5 As shown, in some embodiments, the pull-out head also includes an elastic reset structure 500, which is disposed between the central tube assembly 300 and the water channel assembly 200, so that the water channel assembly 200 can move under the elastic force of the elastic reset structure 500 and reset from the second position to the first position, thereby realizing the automatic reset of the water channel assembly 200 and saving manpower.

[0067] Specifically, the elastic reset structure 500 can be a spring or other components with elastic recovery properties.

[0068] Reference Figures 1 to 9 As shown in the figure, this application embodiment also provides a pull-out faucet, including a faucet body 600 and a pull-out head, the pull-out head being connected to the faucet body 600.

[0069] The specific structure and implementation principle of the pull-out head in this embodiment are the same as those of the pull-out head provided in the above embodiments, and can bring the same or similar technical effects. They will not be described in detail here, but can be referred to the description of the above embodiments.

[0070] In practice, the inlet connector 370 of the pull-out head is threadedly connected to the outlet connector 620 on the pull-out tube 610 of the faucet body 600. The outlet connector 620 is fixed to the pull-out tube 610 by a snap fastener. The pull-out tube 610 is fixed to the bend 630 of the faucet body 600. Therefore, under normal conditions, the pull-out head is hung on the bend 630 by the snap fastener connection between the outlet connector 620 and the pull-out tube 610, and by the pulling force transmitted by the counterweight 640 through the pull-out tube 610. At this time, when the faucet is pulled, water flows through, and the pull-out head outputs soft water under the action of the elastic reset structure 500. Gently pulling the outer casing 100 overcomes the elasticity of the elastic reset structure 500, thus satisfying the force required to switch the water spray pattern. The outer casing 100 and the water channel assembly 200 move downward relative to the central tube assembly 300, from the first position to the second position. At this time, the pulling force of the outer casing 100 is less than the pulling force of the counterweight 640 and the snapping force between the water outlet connector 620 and the pull tube 610. Therefore, the pull head is already hooked on the bend 630, but the water spray is switched to blade water, and this position can be maintained under water pressure. When the water is turned off, the water channel assembly 200 and the outer casing 100 automatically reset to the soft water state under the elasticity of the elastic reset structure 500, or the user can gently push the outer casing 100 upward to reset to the soft water state.

[0071] Alternatively, when the user pulls the pull-out head with greater force, that is, when the pull-out head is pulled out from the bend 630, the elastic force of the elastic reset structure 500 is also overcome. At this time, the water output mode of the blade water can also be switched. When the water is turned off, it can automatically reset to the soft water output mode, or when the pull-out head is returned to the bend 630, it can automatically reset to the soft water output state.

[0072] In the description of the embodiments of this application, specific features, structures, materials or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0073] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
