Description

Technical Field

[0001] This invention relates to the field of bathroom fixtures, and in particular to a spray gun shower head. Background Technology

[0002] Existing spray gun showerheads typically use a three-button switch to change the water flow mode, meaning users can only switch between three preset water spray patterns. During use, users are prone to accidentally pressing the button, for example, when selecting the showerhead mode, they might accidentally press the button to switch to the spray gun mode, causing an unexpected change in the water flow pattern and resulting in the user getting wet unintentionally, thus affecting the user experience.

[0003] Furthermore, many existing spray guns lack effective water-stopping functions. When users need to temporarily stop the water flow, they can only do so by manually turning off the water supply or completely releasing the spray gun switch, which is inconvenient and may waste water. Therefore, there is an urgent need for an improved spray gun design that can provide multiple water spray options, reduce the risk of misoperation, and has an effective water-stopping function to enhance user experience and efficiency. Summary of the Invention

[0004] The main objective of this invention is to overcome the shortcomings of existing spray gun showerheads, such as lack of water-stopping function and easy accidental activation. This invention proposes a spray gun showerhead that solves the problems of lack of water-stopping function and easy accidental activation in existing spray gun showerheads through the design of push button assembly and button assembly, thereby improving user experience and usage efficiency.

[0005] The present invention adopts the following technical solution:

[0006] A spray gun shower head includes a body, a faceplate assembly, and a water distribution assembly. The body has a water inlet channel and a mounting groove. The faceplate assembly is installed in the mounting groove and has a spray gun channel and a shower channel. The water distribution assembly is installed between the faceplate assembly and the inner wall of the mounting groove and has a water distribution chamber and a switching element. The water distribution chamber is connected to the water inlet channel, the spray gun channel, and the shower channel. The switching element is located in the water distribution chamber. The shower head also includes a push button assembly and a button assembly. The push button assembly is located at the handle of the body and has a push rod that is inserted into the mounting groove. The first end of the push rod is connected to the switching element to convert the linear movement of the push rod into the circumferential movement of the switching element and block the water inlet of the spray gun channel or the shower channel. The button assembly passes through the mounting groove and has a piston rod that is inserted into the spray gun channel and can move axially. The piston rod can be pressed or released to open or close the water outlet of the spray gun channel.

[0007] The switching component includes a rocker arm and a rotating component. One end of the rotating component has a connecting part that can be rotatably connected to the faceplate assembly, and the other end has a sealing part. One end of the rocker arm is fixed to the rotating component and has a transmission hole extending along its length. The first end of the push rod has a protrusion that slides in conjunction with the transmission hole. The linear movement of the push rod drives the sealing part to rotate around the connecting part through the cooperation between the protrusion and the transmission hole, thus achieving circumferential movement.

[0008] The sealing part includes a receiving groove, a movable part, and an elastic part. The receiving groove has an opening opposite to the faceplate assembly. The movable part is located inside the receiving groove. The elastic part is disposed between the movable part and the inner wall of the receiving groove to drive the movable part to block the water inlet of the spray gun channel or shower channel.

[0009] The system is equipped with at least one shower head channel and at least one spray gun channel; each spray gun channel is equipped with a second water inlet and a spray gun outlet; each shower head channel is equipped with a first water inlet and a shower head outlet, and the first and second water inlets are distributed circumferentially at intervals; when any first water inlet is not blocked, the corresponding shower head channel is connected, and the remaining water inlets are blocked; when any second water inlet is not blocked, the corresponding spray gun channel is connected, and the remaining water inlets are blocked.

[0010] It is equipped with two shower head channels and one spray gun channel; each shower head channel has a first water inlet and a shower head outlet, and the spray gun channel has a second water inlet; the two first water inlets and the second water inlet are distributed circumferentially; when the switching device connects the second water inlet and closes the two first water inlets, the spray gun channel is connected; when the switching device connects one first water inlet and closes the second water inlet and the other first water inlet, one of the shower head channels is connected; when the switching device connects the two first water inlets and closes the second water inlet, the other shower head channel is connected.

[0011] The spray gun channel is also provided with a water inlet. The water inlet is located between or near one of the two adjacent first water inlets. When the spray gun channel is connected and water is discharged, some water flows through the water inlet and acts on the end face of the switching component opposite to the face cover assembly to reduce the friction between the switching component and the face cover assembly.

[0012] The spray gun channel has a first connecting hole and a second connecting hole on the opposite side of the inner wall of the mounting groove and the face cover assembly. The first connecting hole is connected to the water outlet end of the spray gun channel, and the second connecting hole is connected to the water inlet end of the spray gun channel. The second connecting hole is provided with a water passage hole that is connected to the first connecting hole. The first end of the piston rod passes through the first connecting hole and the second connecting hole in sequence and enters the spray gun channel. A sealing element is also fitted on the piston rod to block or open the water passage hole to open or close the water outlet of the spray gun channel.

[0013] A through-hole is provided on the piston rod to connect the first connecting hole and the second connecting hole; when the piston rod seal closes the water passage hole, the water pressure pushes a small amount of water to flow continuously into the spray gun channel through the through-hole; or the interference fit between the seal and the water passage hole is reduced to allow a small amount of water to seep into the spray gun channel through the sealing gap.

[0014] The back of the main body has a first mounting hole on one side of the cover assembly, which is close to the handle of the main body; the button assembly also has a button and a spring element; the button is movably embedded in the first mounting hole; the spring element is sleeved on the outer periphery of the piston rod; the second end of the piston rod is connected to or abuts against the button; the push rod has a protrusion extending toward the side where the button is located, and is configured such that when the water inlet end of the spray gun channel is blocked, the protrusion blocks the pressing of the button, and when the water inlet end of the spray gun channel is not blocked, the protrusion does not affect the pressing of the button.

[0015] The water distribution assembly also includes a receiving component. One end of the receiving component is provided with a connecting part that connects the insertion handle to the water inlet channel. The other end of the receiving component is covered on the side of the face cover assembly opposite to the inner wall of the mounting groove, and together with the face cover assembly, they enclose a water distribution cavity.

[0016] The handle is provided with a second mounting hole extending along the length of the handle, and the receiving part is provided with a corresponding sliding groove extending along the length of the handle; the push button assembly includes a push button and a slider; the slider is connected to the second end of the push rod and is slidably engaged with the sliding groove; the push button is provided with a pushing part, and the pushing part is fixed relative to the slider.

[0017] As can be seen from the above description of the present invention, compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In this invention, functional optimization is achieved through the collaborative design of the push button assembly and the button assembly: the push rod of the push button assembly converts linear motion into circumferential motion of the switching element, and achieves mode switching by blocking the water inlet of the spray gun or shower head channel; the piston rod of the button assembly directly controls the opening and closing of the water outlet of the spray gun channel through axial movement. The separate design of the push button assembly and the button assembly prevents misoperation and realizes the water-stopping function of the spray gun.

[0019] 2. In this invention, the switching component includes a rocker arm and a rotating component. The elastic element in the rotating component drives the movable component to achieve automatic sealing of the spray gun channel or shower head channel. The rocker arm drives the circumferential movement of the rotating component to ensure the opening and closing sealing of each channel and make the mode switching operation more effortless and smooth.

[0020] 3. In this invention, a water inlet is also provided at the water inlet end of the spray gun channel to form a friction-reducing water flow when the spray gun is spraying water, thereby reducing the frictional resistance between the switching component and the face cover assembly. This solves the problem of excessive switching force required when switching from a small water outlet area (high pressure state of spray gun water) to a large water outlet area (low pressure state of shower head water), making the switching operation more convenient and smooth.

[0021] 4. In this invention, different channels are selectively connected by circumferentially spaced water inlets, enabling flexible combinations of various modes such as spray gun, outer ring shower head, and dual water outlets to meet different water output needs.

[0022] 5. In this invention, the water distribution component adopts a support cover design, which serves as a rigid support to enhance the overall pressure resistance, and integrates the layout of the water distribution chamber and the transmission mechanism within a limited space, thereby achieving functional integration and effective space utilization.

[0023] 6. In this invention, a protrusion is provided on the push rod, and it is configured such that when the water inlet of the spray gun channel is blocked, the protrusion of the push rod automatically blocks the button pressing path, forming a mechanical interlock; when the spray gun channel is open, the protrusion releases the blockage and is configured so that the button can only be pressed when the spray gun channel is not open, to avoid accidental spraying of high-pressure water; this linkage design of the push button assembly and the button assembly realizes the association between the spray gun channel status and the operation permission.

[0024] 7. In this invention, a drip reminder structure is constructed by setting a through hole on the piston rod of the button assembly or by adjusting the sealing gap of the seal. When the spray gun mode is not closed, the residual pressure is actively released, which effectively prevents the risk of seal failure or bursting caused by pressure accumulation and improves the safety of product use.

[0052] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Detailed Implementation

[0053] The present invention will be further described below through specific embodiments.

[0054] See Figures 1 to 25A spray gun shower head includes a body 10, a faceplate assembly 20, a water distribution assembly 30, a push button assembly 40, and a button assembly 50. The body 10 has a handle 12, a water inlet channel 13, and a mounting groove 11. The water inlet channel 13 is located inside the handle 12. The mounting groove 11 is located at one end of the handle 12 and has an opening on the front of the body 10. The front of the body 10 refers to the side of the faceplate assembly 20 facing the user when in use; the back is the side opposite to the front. The faceplate assembly 20 is mounted in the mounting groove 11 and has a spray gun channel 20a and a shower head channel 20b. The spray gun channel 20a is used to output water from the spray gun, and the shower head channel 20b is used to output water from the shower head. The water distribution assembly 30 is installed between the faceplate assembly 20 and the inner wall of the mounting groove 11 and is provided with a water distribution chamber 31 and a switching element 32. The water distribution chamber 31 is connected to the water inlet channel 13, the spray gun channel 20a, and the shower channel 20b. The switching element 32 is located inside the water distribution chamber 31. The push button assembly 40 is located at the handle 12 of the body 10 and is provided with a push rod 41 that is inserted into the mounting groove 11. The first end of the push rod 41 is connected to the switching element 32 to convert the linear movement of the push rod 41 into the circumferential movement of the switching element 32. The circumferential movement of the switching element 32 blocks the water inlet of the spray gun channel 20a or the shower channel 20b. The button assembly 50 passes through the mounting groove 11 and is provided with a piston rod 51 that is inserted into the spray gun channel 20a and can move axially. The piston rod 51 can be pressed or released and moved axially along the piston rod 51 to open or close the water outlet of the spray gun channel 20a.

[0055] In this embodiment, functional optimization is achieved through the collaborative design of the push button assembly 40 and the button assembly 50: the push rod 41 of the push button assembly 40 converts linear motion into circumferential motion of the switching element 32, and achieves mode switching by blocking the water inlet of the spray gun channel 20a or the shower head channel 20b; the piston rod 51 of the button assembly 50 directly controls the opening and closing of the water outlet of the spray gun channel 20a through axial movement.

[0056] The push-button assembly 40 and the button assembly 50 employ a separate operating structure (the push rod 41 and piston rod 51 operate independently), avoiding the accidental activation problem of traditional three-position buttons. Users need to clearly identify the different components to switch modes or turn the spray gun on and off, significantly reducing the probability of accidental switching. The button assembly 50 can instantly shut off the spray gun water flow through the axial movement of the piston rod 51, without needing to turn off the water supply, solving the problem of existing spray guns lacking a quick water-stopping function, thus balancing convenience and water conservation. The division of labor between the push-button assembly 40 controlling mode switching and the button assembly 50 controlling the spray gun's on and off conforms to the user's intuitive operating habits, enhancing efficiency and user experience.

[0057] In this embodiment, see Figures 4-8The switching component 32 includes a rocker arm 32a and a rotating component 32b. One end of the rotating component 32b is provided with a connecting part 32c for rotatable connection with the faceplate assembly 20. The axis of rotation of the connecting part 32c is parallel to the central axis of the faceplate assembly 20. The other end of the rotating component 32b is provided with a sealing part 32d. One end of the rocker arm 32a is fixed relative to the connecting part 32c. The rocker arm 32a is also provided with a transmission hole 32e extending along the length of the rocker arm 32a. The first end of the push rod 41 is provided with a protrusion 41a to pass through the transmission hole 32e. When the push rod 41 moves linearly, the rocker arm 32a and the rotating component 32b are driven to move in conjunction through the cooperation of the protrusion 41a and the transmission hole 32e, so that the sealing part 32d rotates around the connecting part 32c, thereby realizing circumferential movement. The push rod 41 indirectly controls the rotating component 32b via the lever 32a. Compared to direct button switching, the direction of force must be clearly defined to trigger the mode switch, effectively preventing accidental changes in the water flow mode. Furthermore, the linkage design between the lever 32a and the rotating component 32b converts the linear motion of the push rod 41 into a rotational motion, reducing the user's effort when switching modes and improving the comfort of the hand.

[0058] In this embodiment, multiple water outlet modes can be set according to the number and combination of the shower head channel 20b and the spray gun channel 20a, and precise positioning is achieved through the gear structure. The transmission hole 32e is located between the two ends of the swing rod 32a, and the other end of the swing rod 32a is provided with a slot 32f. A positioning block 33 and an elastic element 34 are arranged in the slot 32f, and the elastic element 34 abuts against the positioning block 33 and the inner wall of the slot. The face cover assembly 20 is provided with gear holes 21g in number corresponding to the water outlet modes at positions opposite to the slot 32f. When the push rod 41 is pushed, the protrusion 41a moves along the transmission hole 32e to drive the swing rod 32a to swing, so that the positioning block 33 elastically inserts into the corresponding gear hole 21g, thereby completing the water outlet mode switching. The elastic element 34 provides both restoring force and positioning stability.

[0059] Furthermore, the sealing part 32d includes a receiving groove 35, a movable member 36, and an elastic member 34. The receiving groove 35 has an opening opposite to the faceplate assembly 20. The movable member 36 is located inside the receiving groove 35. The elastic member 34 is disposed between the movable member 36 and the inner wall of the receiving groove 35. The movable member 36 is driven by the elastic member 34 to block the water inlet end of the shower channel 20b or the spray gun channel 20a.

[0060] In this embodiment, at least one shower channel 20b and at least one spray gun channel 20a are provided. Each spray gun channel 20a is provided with a second water inlet 21b and a spray gun outlet. Each shower channel 20b is provided with a first water inlet 21a and a shower outlet. The first water inlet 21a and the second water inlet 21b are distributed circumferentially. Different shower channels 20b are connected by connecting different first water inlets 21a and blocking other water inlets. Different spray gun channels 20a are connected by connecting different second water inlets 21b and blocking other water inlets. When any of the first water inlets 21a is not blocked, the corresponding shower head channel 20b is connected, and the remaining water inlets (including the second water inlet 21b and / or the first water inlet 21a) are blocked by the blocking part 32d; when any of the second water inlets 21b is not blocked, the corresponding spray gun channel is connected, and the remaining water inlets (including the second water inlet 21b and / or the first water inlet 21a) are blocked.

[0061] In practical applications, the number of shower channel 20b and spray gun channel 20a can be set according to requirements. It can be one shower channel 20b and one spray gun channel 20a, two shower channels 20b and spray gun channel 20a, or one spray gun channel 20a and two shower channels 20b. Taking a shower channel 20b and a spray gun channel 20a as an example: each shower channel 20b is provided with a first water inlet 21a and a shower outlet, and the spray gun channel 20a is provided with a second water inlet 21b; the two first water inlets 21a and the second water inlet 21b are distributed circumferentially; the spray gun channel 20a is connected by connecting the second water inlet 21b and closing the two first water inlets 21a, one shower channel 20b is connected by connecting one first water inlet 21a and closing the second water inlet 21b and the other first water inlet 21a, and the other shower channel 20b is connected by connecting the two first water inlets 21a and closing the second water inlet 21b.

[0062] Furthermore, a water inlet hole 21e is provided at the water inlet end of the spray gun channel 20a. The water inlet hole 21e is located between or near one of the two adjacent first water inlets 21a, so that when the spray gun channel 20a is switched on, this water inlet hole 21e and the first water inlet hole 21a are blocked by the movable part 36. When the spray gun channel 20a is on and water is flowing out, some water flows through the water inlet hole 21e and acts on the end face of the movable part 36 opposite to the faceplate assembly 20, reducing the friction between the two. This design solves the problem of excessive switching force required when switching from a small water outlet area (high pressure state of spray gun water) to a large water outlet area (low pressure state of shower head water), making the switching operation easier and smoother.

[0063] The sealing part 32d is also provided with a sealing plug 37, which is located outside the receiving groove 35 and is configured such that when the second water inlet hole 21b of the spray gun channel 20a is blocked, the sealing plug 37 just blocks the water passage hole 21e, so as to prevent water from entering the spray gun channel 20a from the water passage hole 21e when the shower head is spraying water, causing water leakage.

[0064] The spray gun channel 20a has a first connecting hole 21c and a second connecting hole 21d on the opposite side of the inner wall of the faceplate assembly 20 and the mounting groove 11. The first connecting hole 21c is connected to the water outlet end of the spray gun channel 20a, and the second connecting hole 21d is connected to the water inlet end of the spray gun channel 20a, i.e., the second water inlet hole 21b. The second connecting hole 21d has a water passage hole 21f that is connected to the first connecting hole 21c. The first end of the piston rod 51 of the button assembly 50 passes through the first connecting hole 21c in sequence. 1c and the second connecting hole 21d enter the spray gun channel 20a. A sealing element 52 is also fitted onto the piston rod 51. Axial movement of the piston rod 51 causes the sealing element 52 to block or open the water passage 21f, thus opening or closing the water outlet of the spray gun channel 20a. That is, when the sealing element 52 blocks the water passage 21f, the water inlet and outlet of the spray gun channel 20a are not connected; when the sealing element 52 opens the water passage 21f, the water inlet and outlet of the spray gun channel 20a form a passage. (See also...) Figures 18 to 20 .

[0065] A first mounting hole 14 is provided on one side of the back of the main body 10 opposite the cover assembly 20. The first mounting hole 14 is used to install the button assembly 50, which is close to the handle 12 of the main body 10. The button assembly 50 is also provided with a button 53 and an elastic element 34. The button 53 is movably embedded in the first mounting hole 14. The elastic element 34 is sleeved on the outer periphery of the piston rod 51 and is used to drive the button 53 back to its original position. The second end of the piston rod 51 is connected to or abuts against the button 53. Pressing or releasing the button 53 drives the piston rod 51 to move axially. The end of the piston rod 51 that is inserted into the spray gun channel 20a can also be provided with an elastic element 34 to drive the piston rod 51 back to its original position when the button 53 is released. After the push rod 41 of the push button assembly 40 is inserted into the mounting groove 11, it is located on the side of the piston rod 51. A protrusion 42 extending towards the side where the button 53 is located is provided between the first end and the second end of the push rod 41. The protrusion 42 is located between the button 53 and the faceplate assembly 20. When the push rod 41 moves, the position of the protrusion 42 relative to the button 53 will also change. In this embodiment, when the water inlet end of the spray gun channel 20a is blocked, the protrusion 42 blocks the pressing of the button 53, that is, the button 53 cannot be pressed at this time; when the water inlet end of the spray gun channel 20a is not blocked, the protrusion 42 does not affect the pressing of the button 53, and the button 53 can be pressed at this time.

[0066] The linkage design between the push button assembly 40 and the button assembly 50 establishes a connection between the state of the spray gun channel 20a and the operating permissions. When the water inlet of the spray gun channel 20a is blocked, the protrusion 42 of the push rod 41 automatically blocks the pressing path of the button 53, forming a mechanical interlock; when the spray gun channel 20a is opened, the protrusion 42 releases the blockage.

[0067] The water distribution assembly 30 also includes a receiving member 38, which extends along the length of the handle 12. One end of the receiving member 38 has a connecting portion 38a that connects the handle 12 to the water inlet channel 13. The connecting portion 38a and the water inlet channel 13 can be respectively configured as tubular, and their opposite ends can be sleeved together and sealed with a sealing ring. The other end of the receiving member 38 is configured as a cover structure, which covers the side of the faceplate assembly 20 opposite to the inner wall of the mounting groove 11, and together with the faceplate assembly 20, forms the water distribution cavity 31. The button 53 of the button assembly 50 is rotatably connected to the receiving member 38 to form a stable fulcrum, converting the pressing action into axial displacement. The connecting portion 32c of the rotating member 32b passes through the receiving member 38 to connect with the rocker arm 32a. The push rod 41 is close to the side of the receiving member 38 where the rocker arm 32a is located. The receiving member 38 also has a clearance hole 38b on the area opposite to the button 53. The receiving component 38, together with the cover assembly 20, forms a water distribution chamber 31 and a passage connecting the water inlet channel 13. The receiving component 38 serves as a rigid support to enhance the overall pressure resistance.

[0068] A second mounting hole 15 extending along the length of the handle 12 is provided on the front of the handle 12 near the mounting groove 11. This second mounting hole 15 is used to mount the push button assembly 40. A sliding groove 38c extending along the length of the handle 12 is provided on the receiving member 38 at a position corresponding to the second mounting hole 15. The push button assembly 40 includes a push button 46 and a slider 45; the slider 45 is connected to the second end of the push rod 41 and is in sliding engagement with the sliding groove 38c to ensure more reliable movement of the push button 46 and the slider 45 and avoid jamming or deflection; the push button 46 is provided with a pushing part 44, which is fixed relative to the slider 45. The pushing part 44 and the slider 45 can be fixed relative to each other by means of a concave-convex fit or a snap-fit ​​fit. The push button assembly 40 may also be provided with a decorative cover 43, which is installed at the second mounting hole 15 and has a hole for accommodating the pushing part 44.

[0069] In this embodiment, see Figure 9 , Figure 10The faceplate assembly 20 can be implemented using a common faceplate structure, which includes a faceplate 21, a water distribution plate 23, and a support plate 24. The support plate 24 is opposite to the inner wall of the mounting groove 11 and is provided with a first water inlet 21a, a second water inlet 21b, a water passage 21e, a first connecting hole 21c, a second connecting hole 21d, and a stop hole 21g. The water distribution plate 23 is fixed to the side of the support plate 24 facing away from the inner wall of the mounting groove 11 and forms a spray gun channel 20a and a shower channel 20b therewith. The water distribution plate 23 is also provided with at least one water outlet group 23a, which corresponds to the shower channel 20b. That is, one shower channel 20b corresponds to one water outlet group 23a, and two shower channels 20b correspond to two water outlet groups 23a. Each water outlet group is provided with multiple water outlets. The spout plate 25 is disposed on the side of the water distribution plate 23 opposite to the support plate 24 and forms at least one water outlet cavity 26 therewith. The number of water outlet cavities 26 corresponds to the number of water outlet hole groups 23a. Taking two water outlet cavities 26 as an example, the first water outlet cavity is located in the middle, and the second water outlet cavity is annular and arranged around the first water outlet cavity. The spout plate 25 is provided with an array of spouts that communicate with each water outlet cavity 26. For example, the spout located in the middle communicates with the first water outlet cavity, and the annularly distributed spouts communicate with the second water outlet cavity, realizing differentiated shower head water outlet modes. The cover 21 is disposed on the side of the spout plate 25 opposite to the water distribution plate 23 and is fixed relative to the mounting groove 11. The cover 21 is provided with holes for the spouts to pass through.

[0070] The faceplate assembly 20 also includes a nozzle 27, which is fixedly installed on one side of the inner wall of the mounting groove 11 of the support plate 24, near the edge. The nozzle 27 and the support plate 24 can be secured with screws. A hole is opened on the side wall of the mounting groove 11 of the body 10 relative to the position of the nozzle 27 to serve as the water outlet end of the nozzle 27. The support plate 24 is also provided with a spray water outlet hole 28, which serves as the water outlet end of the spray gun channel 20a and communicates with the nozzle 27.

[0071] In this embodiment, when switching to the spray gun channel 20a and releasing button 53, a dripping mechanism is used as a safety reminder to prevent internal pressure buildup due to user negligence in not turning off the water in time. Specifically, a through-hole is provided on piston rod 51, connecting the first connecting hole 21c to the second connecting hole 21d. When piston rod 51 seal 52 closes the water passage 21f, water pressure pushes a small amount of water through the through-hole to continuously flow into spray gun channel 20a, eventually slowly seeping out from nozzle 27. An alternative solution is to moderately reduce the interference fit of piston rod 51 seal 52, allowing a small amount of water to seep into spray gun channel 20a through the sealing gap, thus achieving the same dripping reminder function. Both methods effectively release residual system pressure, avoiding the risk of bursting due to excessive pressure.

[0072] In this embodiment, the spray gun and showerhead control different water output levels through mechanical linkage. When the user pushes the push button assembly 40, the push rod 41 drives the swing rod 32a to swing, driving the rotating part 32b to rotate circumferentially around the connecting part 32c, causing the sealing part 32d to sequentially switch the opening and closing states of different water inlet channels. Taking the three-level water output mode as an example, including spray gun water output, outer ring showerhead water output, and middle and outer ring showerhead water output, its working principle is as follows:

[0073] See Figures 21-23 When switching to the spray gun water output mode, pushing the push button 46 causes the push rod 41 to drive the rotating part 32b to move the sealing part 32d to the water inlet end of the spray gun channel 20a. At this time, the second water inlet hole 21b is fully opened, and the first water inlet hole 21a and the water passage hole 21e are sealed by the moving part 36. Pressing the button assembly 50 causes the piston rod 51 to move axially, causing the sealing part 52 to disengage from the water passage hole 21f. Water flows through the second water inlet hole 21b, the first connecting hole 21c, the second connecting hole 21d, and the spray outlet hole 28, and is sprayed out from the nozzle 27 to form a high-pressure jet. After releasing the button 53, the elastic part 34 drives the button 53 and the piston rod 51 to reset, cutting off the connection between the first connecting hole 21c and the second connecting hole 21d. At the same time, a small amount of seepage is maintained through the bypass through hole to provide a pressure reminder. See also Figure 24 When switching to the outer ring shower mode, pushing the push button 46 causes the rotating part 32b to move the sealing part 32d to the water inlet end of the shower channel 20b on the outer ring. At this time, the corresponding first water inlet hole 21a opens, while the second water inlet hole 21b and another first water inlet hole 21a are sealed. Water flows through the corresponding shower channel 20b into the water outlet chamber 26, and forms the outer ring shower outlet through the water outlet hole group 23a on the water distribution plate 23. See also Figure 25 When switching to the dual-outlet mode of the middle and outer ring shower heads, push the push button 46, and the rotating part 32b will drive the sealing part 32d to move to the water inlet end of the spray gun channel 20a. The two first water inlets 21a open at the same time, and the second water inlet 21b and the water passage 21e are sealed. The water flows through the two shower head channels 20b and enters the water distribution chamber 31 of the middle and outer ring at the same time, achieving a full-coverage water outlet effect.

[0074] The entire switching process described above is achieved through the mechanical transmission of the push button assembly 40 to select the mode, the button assembly 50 to control the opening and closing of the spray gun, and each gear is positioned by the cooperation of the positioning block 33 and the gear hole 21g, ensuring reliable water output mode switching and smooth operation.
