Description

Technical Field

[0001] This invention relates to the field of showerhead technology, and more specifically, to a top spray that allows for convenient switching of water paths. Background Technology

[0002] Multifunctional top-mounted sprayers primarily offer three switching methods: button switching, rotating cover switching, and pressing cover switching. Button switching involves placing the button on the side, and the button is relatively small, often requiring the user to look up to operate it, which can lead to water entering the eyes. Rotating cover switching, when the spray area is large, requires both hands to operate. Press-cover switching, with its larger cover area, allows for one-handed operation without needing to look up, making switching convenient. However, current pressing cover switching methods, such as the novel concealed multifunctional switching top-mounted sprayer disclosed in CN207056829U, require pushing the entire cover upwards to overcome significant water pressure, necessitating considerable pressing force.

[0003] In view of this, the applicant has put forward this application after studying the existing technology, which overcomes the problem that the current pressing method of switching the face cover requires a lot of pressing air. The water circuit can be switched by pressing only one side of the face cover. The operation is simple and does not require too much pressing air. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a top spray with convenient water path switching, including a housing, a rotating mechanism, a driving device, and a switching mechanism;

[0005] The housing includes a top cover and a water outlet cover. The top cover is provided with a water inlet, and the water outlet cover is slidably connected to the bottom of the top cover.

[0006] The rotating mechanism is located inside the housing, and has a water inlet channel connected to the water inlet. The switching mechanism is connected below the rotating mechanism. The rotating mechanism is configured such that when one side of the water outlet cover is pressed, it can drive the switching mechanism to rotate.

[0007] The switching mechanism includes a water distribution body and a switching component. The water distribution body is provided with a water inlet hole that communicates with the water inlet channel and multiple water passage holes that are connected to the water outlet function of the shower head. The driving device is connected to the switching component. The driving device is configured such that when one side of the water outlet cover is pressed, it can drive the switching component to rotate, so that the water inlet hole can selectively connect to some of the water passage holes, thereby realizing the switching of the water outlet function of the shower head.

[0008] As a further optimization, a ball-end nut is also included, and a ball-end retaining ring adapted to the ball-end nut is provided on the top of the upper cover, and the upper cover is movably connected to the ball-end nut through the ball-end retaining ring.

[0009] As a further optimization, the rotating mechanism includes a rotating shaft, a rotating sleeve, and a rotating disk. The rotating shaft is connected above the rotating disk, the rotating sleeve is engaged with the rotating shaft, and the rotating sleeve passes through the rotating disk and is engaged with the water distribution body. The water inlet channel is disposed inside the rotating shaft and the rotating sleeve.

[0010] As a further optimization, the switching component includes a water distribution plate, which is disposed above the water passage hole and has at least one first water distribution hole adapted to the water passage hole.

[0011] As a further optimization, an elastic component is also provided above the water distribution plate, and a sealing ring is clamped between the water distribution body and the water distribution plate, and the elastic component presses the water distribution plate tightly onto the sealing ring.

[0012] As a further optimization, the drive device includes a fixed base, a fixed block, a rotating wheel, a push rod, a push block, and a reset component for resetting the push rod. The fixed base is bolted to the water distribution body. The rotating wheel is rotatably connected to the fixed base and connected to the water distribution plate via a pin. The fixed block is fixedly connected to the upper cover. The push block is connected to the water outlet panel via a pin. The push rod is movably connected to the fixed base, with one end abutting against the rotating wheel and the other end abutting against the push block.

[0013] As a further optimization, the drive device also includes a stop block corresponding to the rotating wheel, the stop block being connected to the fixed base, the reset member being a spring connected to the fixed base, and the push rod being provided with an abutment arm for pressing the spring.

[0014] As a further optimization, the switching component includes an upper water passage body, a lower water passage body, and an eccentric surface. The upper water passage body is connected to the water distribution body and has a plurality of second water distribution holes that are connected to the water passage holes. The lower water passage body is connected below the upper water passage body. The eccentric surface is sandwiched between the upper water passage body and the lower water passage body. A sliding block is installed on the side wall of the eccentric surface. An upper inclined surface is provided on the upper water passage body, and a lower inclined surface adapted to the upper inclined surface is provided on the lower water passage body. The sliding block engages between the upper inclined surface and the lower inclined surface.

[0015] As a further optimization, the driving device further includes a top surface, a top rod, a top shaft, and a return spring. The top surface is fixedly connected to the upper cover. The top end of the top rod abuts against the top surface, and the lower end is connected to the eccentric surface. The return spring is connected below the eccentric surface and sleeved on the top shaft. The lower end of the top shaft is connected to the lower water body.

[0016] As a further optimization, the water outlet cover includes a connecting plate, a water-passing plate, and a panel. The water-passing plate is disposed between the connecting plate and the panel, and a sealing ring is provided thereon, so that an inner water outlet cavity and an outer water outlet cavity are formed between the water-passing plate and the connecting plate. The connecting plate is provided with an inner water outlet hole and an outer water outlet hole that are respectively connected to the inner water outlet cavity and the outer water outlet cavity. The panel is provided with a first functional water outlet hole and a second functional water outlet hole that are respectively connected to the inner water outlet cavity and the outer water outlet cavity.

[0017] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0018] This invention provides a convenient top spray for switching water paths. A rotating mechanism is installed inside the housing, with the water inlet channel located within it. A switching mechanism is connected below the rotating mechanism. When one side of the water outlet cover is pressed, the rotating mechanism rotates, causing the switching mechanism below to rotate at a certain angle. This allows the water flow channel to rotate along with the water flow, preventing the water flow from being compressed and generating a reverse water pressure force on the water outlet cover. Pressing one side of the water outlet cover eliminates the need to overcome additional water pressure, making pressing easier. Furthermore, the water outlet cover, driving device, and rotating mechanism form a lever that reduces effort, allowing the switching element in the switching device to rotate easily without applying excessive pressure when pressing one side of the panel, thus completing the water flow function switch. This makes pressing easier and provides a better switching feel. Attached Figure Description

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0034] Example 1:

[0035] Depend on Figures 1 to 5As shown, the present invention provides a top spray with convenient water path switching, including a housing 1, and a rotating mechanism 2, a driving device 3, and a switching mechanism 4 disposed inside the housing; the housing 1 includes an upper cover 11 and a water outlet cover 12, the upper cover being provided with a water inlet 111, and the water outlet cover 12 slidingly connected to the lower part of the upper cover 11; the switching mechanism 4 includes a water distribution body 41 and a switching element 46, the water distribution body 41 being provided with multiple water passage holes 412 for corresponding to the water outlet function of the shower head, and the switching element 46 being a water distribution plate 42, the water distribution plate 42 being provided with multiple first water distribution holes 421 that cooperate with the water passage holes 412; the rotating mechanism 2 includes a rotating shaft 22, a rotating sleeve 23, and a rotating disk 24, the rotating shaft 22 being connected above the rotating disk 24, the rotating sleeve 23 having slots 231 at both ends, and the rotating shaft 22 and the water distribution body 41 respectively being provided with retaining rings 221 adapted to the slots 231, through the slots With the cooperation of 231 and 221, one end of the rotating sleeve 23 is engaged with the rotating shaft 22, and the other end passes through the rotating disk 24 and is engaged with the water distribution body 41. The rotating shaft 22 and the rotating sleeve 23 are provided with a water inlet channel 21 that communicates with the water inlet 111. The water distribution body 41 is provided with a water inlet hole 411 that communicates with the water inlet channel 21. Inside the water distribution body 41, a water-containing cavity is provided between the water inlet hole 411 and the water passage hole 412. The driving device 3 is connected to the water distribution plate 42. When one side of the water outlet cover 12 is pressed, the rotating sleeve 23 rotates around the rotating shaft 22, driving the rotating disk 24 below and the switching mechanism 4 to rotate together. At the same time, the driving device 2 drives the water distribution plate 42 to rotate relative to the water distribution body 41, so that the first water distribution hole 421 on the water distribution plate 42 can selectively connect with part of the water passage hole 412, thereby enabling the water inlet hole 411 to communicate with the part of the water passage hole 412 and realize the switching of the water outlet function. The water inlet channel 21 is located inside the rotating shaft 22 and the rotating sleeve 23. Therefore, when one side of the panel is pressed, the water inlet channel 21 will rotate accordingly, so that it will not generate reverse pressure on the water flow. Therefore, it will not be affected by the water pressure when it is not pressed, and the required pressing force is relatively small.

[0036] An elastic component 44, which can be a spring, is also provided above the water distribution plate 42. A sealing ring 43 is clamped between the water distribution body 41 and the water distribution plate 42. The sealing ring 43 has a through hole corresponding to the position of the water passage hole 412. The elastic component 44 presses the water distribution plate 42 tightly onto the sealing ring 43, so that there is no leakage between the water distribution plate 42 and the water distribution body 41, and water is prevented from flowing out from other unconnected water passage holes. There are at least two water passage holes 412, and the water passage holes 412 are arranged in a ring array. The angle between each pair of adjacent water passage holes is the same, and each water passage hole corresponds to a water path with a water outlet function. Water flows in from the water inlet 111, passes through the water inlet channel 21, enters the water-containing cavity in the water distribution body 41 through the water inlet hole 411, then passes through the first water distribution hole 421 and the water passage hole 412 connected to the first water distribution hole 421, and finally flows out from the water outlet cover 12. To better illustrate the water path switching process, the water passage 412 is divided into a first water passage, a second water passage, and a third water passage. When the top spray is in normal water condition, the first water distribution hole 421 is connected to the first water passage. Pressing one side of the water outlet cover 12 causes the drive device 3 to drive the water distribution plate 42 to rotate relative to the water distribution body 41, so that the first water distribution hole 421 rotates from the position of the first water passage to the position of the second water passage, thereby connecting the second water passage. Pressing the water outlet panel again causes the drive device 3 to drive the water distribution plate 42 to rotate relative to the water distribution body 41 again, so that the first water distribution hole 421 rotates from the position of the second water passage to the position of the third water passage, thereby connecting the third water passage. This cycle repeats to achieve the water outlet function switching.

[0037] The driving device includes a fixed base 31, a fixed block 32, a rotating wheel 33, a push rod 34, a push block 35, and a reset component 36 for driving the push rod to reset. The fixed base 32 is bolted to the water distribution body 41. The rotating wheel 33 is rotatably connected to the fixed base 31 and connected to the water distribution plate 42 via a pin 37. The fixed block 32 is fixedly connected to the upper cover 11, and the distance from the fixed block 32 to the rotating shaft 22 is less than the distance from the pressing point on the side of the water outlet cover to the rotating shaft 22. The push block 35 abuts against the lower part of the fixed block 32. The push block 35 has a first connecting hole 381. The water outlet cover 12 is provided with a connecting seat 351, which has a second connecting hole 382. The connecting seat 351 is composed of two parallel plates, and the push block 35 is clamped between the two plates. Between the panels, a pin 38 passes through a connecting hole on the connecting seat 351 and the push block 35, connecting the push block to the connecting seat 351. The push rod 34 is movably connected to the fixed seat 31, with one end abutting against the rotating wheel 33 and the other end abutting against the push block 35. The reset element 36 can be a spring, with one end connected to the fixed seat 31 and the other end connected to the push rod 34. The push rod 34 is provided with abutting arm 341 for pushing the spring. When one side of the panel is pressed, the fixed block 32 pushes the push block 35 to rotate around the pin. When the push block 35 rotates, it pushes the push rod 34 forward, causing the push rod 34 to push the rotating wheel 33 to rotate. At the same time, the abutting arm 341 presses the spring, causing the spring to store force. When the panel is released, the spring force pushes the push rod 34, causing it to drive the push block 35 to reset. The two plates of the connecting seat 351 can prevent the push block 35 from shifting during rotation. During the pressing process of the panel, the rotating mechanism 2 and the driving device 3 can form a lever structure with the rotating shaft 22 as the fulcrum. The fixed block 32 is the resistance point, and the pressing point of the water outlet cover is the power point. The distance from the fixed block 32 to the rotating shaft 22 is less than the distance from the pressing point on the side of the water outlet cover to the rotating shaft 22, making the power arm longer than the resistance arm. Therefore, a force-saving lever is formed, making it easier to press the water outlet cover 12 and providing a better user experience. The driving device 3 also includes a stop block 39 corresponding to the rotating wheel 33. The stop block 39 is connected to the fixed base 31 to prevent the rotating wheel 33 from rotating in the opposite direction.

[0038] like Figure 5As shown, the top of the upper cover 11 is also secured with a ball head nut 5 using a ball head retainer 112, which allows the top spray to rotate in all directions, making it convenient to adjust the water outlet direction of the top spray. The water outlet cover 12 includes a connecting plate 121, a water passage plate 122, and a panel 123. The water passage plate 122 is disposed between the connecting plate 121 and the panel 123, and a sealing ring 128 is provided on it, so that the water passage plate 122 and the connecting plate 121 form a water outlet inner cavity 124 and a water outlet outer cavity 125. The connecting plate 121 is provided with a water passage inner hole 126 and a water passage outer hole 127 that are respectively connected to the water outlet inner cavity 124 and the water outlet outer cavity 125. The panel 123 is provided with a first functional water outlet hole and a second functional water outlet hole that are respectively connected to the water outlet inner cavity 124 and the water outlet outer cavity 125. The water passage inner hole is connected to the first water outlet hole, and the water passage outer hole is connected to the second water outlet hole. The water outlet inner cavity and the water outlet outer cavity cooperate with the first functional water outlet hole and the second functional water outlet hole of the panel, respectively, so that different functions of water can be output, such as shower water, aerated water, etc.

[0039] Example 2

[0040] This embodiment uses another switching component and driving device, such as Figures 6 to 12As shown, in this embodiment, the switching component 46 includes an upper water passage body 47, a lower water passage body 48, and an eccentric surface 45. The upper water passage body 47 is connected to the water distribution body 41. The upper water passage body 47 is provided with second water distribution holes 472 adapted to the water passage holes 412. The number of second water distribution holes 472 is the same as the number of water passage holes 412. Each second water distribution hole 472 corresponds to and connects to one water passage hole 412. The lower water passage body 48 is connected below the upper water passage body 47. The eccentric surface 45 is sandwiched between the upper water passage body 47 and the lower water passage body 48. 5 is a circular panel with a notch. The eccentric surface 45 allows one of the second water distribution holes to be connected through the notch, while the other two second water distribution holes are blocked by the panel. A sliding block 451 is installed on the side wall of the eccentric surface 45. An upper inclined surface 471 is provided on the upper water passage 47, and a lower inclined surface 481 is provided on the lower water passage 48. The upper inclined surface 471, the lower inclined surface 481 and the sliding block 451 can cooperate to form a meshing transmission. The driving device 3 includes a top surface 61, a push rod 62, a push shaft 63 and a return spring 64. The top surface 61 is fixedly connected to On the top cover 11, the distance between the top surface 61 and the rotating shaft 22 is less than the distance between the pressing point on one side of the water outlet cover 12 and the rotating shaft 22; the upper end of the top rod 62 abuts against the bottom of the top surface 61, and the lower end is rotatably connected to the eccentric surface 45. The return spring 64 is connected below the eccentric surface 45 and sleeved on the top shaft 63. The lower end of the top shaft 63 is connected to the lower water body 48 and is provided with a pressing block 631 for squeezing the return spring 64. When one side of the water outlet cover 12 is pressed, the rotating sleeve 23 rotates around the rotating shaft 23, and the top surface 61 faces downward. Pressing the push rod 62 causes the eccentric surface 45 to move downwards, driving the sliding block 451 to rotate clockwise along the lower inclined surface 481. Simultaneously, the rotation of the sliding block 451 causes the eccentric surface 45 to rotate, and the return spring 64 is compressed and stores force, releasing the water outlet cover 12. The return spring 64 returns to its original position, pushing the eccentric surface 45 and the push rod 62 upwards. At the same time, the sliding block 451 continues to rotate clockwise along the upper inclined surface 471, driving the eccentric surface 45 to rotate, causing the notch on the eccentric surface 45 to rotate to another second water distribution hole, completing the switching of the water outlet function; this cycle repeats. A third spring 129 is provided at the pressing point of the water outlet cover, allowing it to return to its original position more quickly after being released.
