Description

Technical Field

[0001] This utility model relates to a handheld shower head, and more particularly to a handheld shower head with a spray gun function. Background Technology

[0002] Currently, handheld showerheads on the market are mainly divided into two categories based on usage needs: one is a regular showerhead for personal hygiene; the other is a high-powered spray gun showerhead for rinsing bathroom walls and floors. Traditional regular showerheads typically do not have a spray gun function. Therefore, to simultaneously meet the needs of showering and bathroom cleaning, the conventional approach is to have two separate showerheads: one regular showerhead and one spray gun showerhead. However, this solution not only increases purchase costs (including the showerhead itself and piping installation costs) but also occupies more bathroom space.

[0003] To address this issue, designs integrating the spray gun function into ordinary showerheads have emerged on the market. These multi-functional showerheads can satisfy both showering needs and high-pressure rinsing by switching water flow modes. Typically, the showerhead outlet is located on the front of the showerhead, while the spray gun outlet is located at the top. The showerhead contains at least two independent water channels: one or more for regular showering, and another providing a high-pressure water flow for cleaning. Users can select the corresponding water channel using a switching mechanism on the showerhead, thus switching between the desired functions.

[0004] Currently, common switching mechanisms are mainly divided into two types: push-button and push-button. Push-button designs typically have the spray gun function set at the top position. However, this design poses a certain safety hazard: when the shower head is in an upright position, the spray gun nozzle is aimed at the ceiling. If the user accidentally pushes the button directly to the top, the high-pressure water stream will spray directly onto the ceiling, failing to clean the bathroom and potentially damaging ceiling-mounted appliances such as heaters and bathroom exhaust fans, posing a safety risk. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a handheld shower head with a spray gun function that has a simple structure and can effectively prevent the shower head from accidentally switching to the spray gun water path when it is in an upright state.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0007] A handheld shower head with a spray gun function includes a shower head body. A spray gun nozzle is located at the top of the shower head body. A push button is mounted on the shower head body and can be pushed up and down. The shower head body contains a water inlet, at least two water outlets, and a water outlet switching mechanism. The water outlet switching mechanism, driven by the push button, switches the connection between the water inlet and any of the water outlets. One of the water outlets is a spray gun water outlet corresponding to the spray gun nozzle. When the push button is pushed to its highest position, the water outlet switching mechanism switches the connection between the water inlet and the spray gun water outlet. The shower head body includes a blocking element that prevents the push button from being pushed further upward when the shower head body is in an upright position with the spray gun nozzle pointing upwards towards the ceiling. When the shower head body is tilted, the blocking element shifts and releases its blocking effect, allowing the push button to be pushed to its highest position to switch to the spray gun function.

[0008] The aforementioned blocking component is a fan-shaped blocking plate whose width gradually increases from top to bottom. The bottom end face of the blocking plate is an arc-shaped blocking end face that bulges downward in the middle. The upper part of the blocking component is rotatably mounted in the shower head body. The water path switching mechanism includes a switching component driven by the push button and moving synchronously with the push button. A blocking arm is provided on the switching component at the installation position corresponding to the blocking plate. When the shower head body is in an upright state and the push button is in the bottommost position, the arc-shaped blocking end face and the upper end face of the blocking arm are vertically opposite each other and there is a movable gap between them. The straight-line distance of the movable gap along the movement direction of the push button is less than the straight-line distance of the push button from the bottommost position to the topmost position. When the shower head body is tilted, the blocking component rotates, the arc-shaped blocking end face moves to the side, releasing the blocking effect, increasing the upward movement stroke of the blocking arm, and allowing the push button to move to the topmost position.

[0009] The shower head body has a mounting protrusion located from the front to the back, and the upper part of the baffle plate has a mounting hole, through which the baffle plate can be rotatably mounted on the mounting protrusion.

[0010] The shower head body is provided with a horizontal limiting wall, which is set on the mounting protrusion to limit the rotation of the blocking member.

[0011] The mounting protrusions, from the front to the back of the shower head body, are sequentially a rotating mounting part for rotating the blocking member and a limiting part for limiting the installation of the blocking member. The outer diameter of the limiting part is larger than the inner diameter of the mounting hole. The blocking member can be rotatably mounted on the rotating mounting part through the mounting hole and is limited by the limiting part.

[0012] The end corresponding to the rotating mounting part is fixedly installed in the shower head body, the end corresponding to the limiting part is a free end, and the mounting protrusion has an opening groove that divides the mounting protrusion in half to form two movable mounting halves.

[0013] Compared with the prior art, the advantages of this utility model are: simple structure, by setting a blocking component in the shower body, when the shower body is in an upright state and the corresponding spray nozzle of the spray gun is aimed at the ceiling, the blocking push button can continue to be pushed upward, thereby avoiding the high pressure water flow from accidentally hitting the ceiling due to accidental pushing operation, preventing damage to electrical equipment installed on the ceiling, and thus eliminating safety hazards during use.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] As shown in the figure, a handheld shower head with a spray gun function includes a shower head body 1. The top of the shower head body 1 is provided with a spray gun water nozzle P1. A push button 2 is provided on the shower head body 1 that can be pushed up and down. The shower head body 1 is provided with a water inlet 60, at least two water outlets 41 and a water outlet switching mechanism. The water outlet switching mechanism is driven by the push button 2 to switch the connection between the water inlet 60 and any of the water outlets 41. One of the water outlets 41 is the spray gun water outlet corresponding to the spray gun water nozzle P1. When the push button 2 is pushed to the top position, the water outlet switching mechanism switches the connection between the water inlet 60 and the spray gun water outlet. The shower head body 1 is provided with a blocking member 8 to prevent the push button 2 from being pushed further upward when the shower head body 1 is in an upright state and the spray gun water nozzle P1 is facing the ceiling. When the shower head body 1 is tilted, the blocking member 8 moves and releases the blocking effect, so that the push button 2 can be pushed to the top to switch to the spray gun water function.

[0026] In this specific embodiment, the blocking member 8 is a fan-shaped blocking plate with a gradually increasing width from top to bottom. The bottom end face of the blocking plate is an arc-shaped blocking end face 81 that bulges downward in the middle. The upper part of the blocking member 8 is rotatably installed inside the shower body 1. The water circuit switching mechanism includes a switching member 3 driven by the push button 2 and moving synchronously with the push button 2. A blocking arm 309 is provided on the switching member 3 at the installation position corresponding to the blocking plate. When the shower body 1 is in an upright state and the push button 2 is at the bottommost position, the arc-shaped blocking end face 81 and the upper end face of the blocking arm 309 are vertically opposite each other and there is a movable gap J between them. The linear distance of the movable gap J along the moving direction of the push button 2 is less than the linear distance of the push button 2 from the bottommost position to the topmost position. When the shower body 1 is tilted, the blocking member 8 rotates, the arc-shaped blocking end face 81 moves to the side, and the blocking effect is released, so that the upward stroke of the blocking arm 309 increases, and the push button 2 can move to the topmost position. With a simple structure and convenient operation, when the shower body 1 is in an upright position, the arc-shaped blocking end face 81 of the blocking member 8 is located at the bottom of the blocking member 8 under the action of gravity. At this time, the movable gap J between the arc-shaped blocking end face 81 and the upper end face of the blocking arm 309 can only be used by the push button 2 to switch the shower outlet mode of the shower body 1. The travel of this gap makes it impossible for the push button 2 to be pushed to the top position to switch the shower to the spray gun function. If the spray gun function is to be used, the handle of the shower body 1 must be held to tilt the shower body 1. At this time, the blocking member 8 rotates with the tilt of the shower body 1, and the arc-shaped blocking end face 81 moves to the side, releasing the blocking effect. At this time, the upward travel of the blocking arm 309 increases, and the push button 2 can move to the top position to switch to the spray gun function.

[0027] In this specific embodiment, a mounting protrusion T1 is provided inside the shower body 1 from the front to the back. A mounting hole 82 is provided on the upper part of the blocking plate. The blocking plate is rotatably fitted onto the mounting protrusion T1 through the mounting hole 82. The structure is simple and is used to achieve stable rotatable installation of the blocking component 8 inside the shower body 1.

[0028] In this specific embodiment, a transverse limiting wall X1 is provided inside the shower head body 1. The limiting wall X1 is disposed on the mounting protrusion T1 to limit the rotation of the blocking member 8. When the shower head body 1 is tilted, the limiting wall X1 limits the rotation of the blocking member 8, preventing it from rotating excessively and making it difficult to return to the original blocking position.

[0029] In this specific embodiment, the mounting protrusion T1, from the front to the back of the shower body 1, consists of a rotating mounting part T11 for rotating the blocking member 8 and a limiting part T12 for limiting the installation of the blocking member 8. The outer diameter of the limiting part T12 is larger than the inner diameter of the mounting hole 82. The blocking member 8 can be rotatably mounted on the rotating mounting part T11 through the mounting hole 82 and is limited by the limiting part T12.

[0030] In this specific embodiment, the end corresponding to the rotating mounting part T11 is fixedly installed inside the shower head body 1, while the end corresponding to the limiting part T12 is a free end. The mounting protrusion T1 has an opening groove T10, which divides the mounting protrusion T1 in half to form two movable mounting halves. This facilitates the fitting and installation of the blocking member 8. After installation, the limiting part T12 partially returns to its original position without force, achieving stable installation of the blocking member 8.

[0031] In this specific embodiment, the push button 2 is located on the handle 102 of the shower head body 1 and can move up and down along the central axis of the handle 102. The switching element 3 is a switching pipe that runs through the axis. The water path switching mechanism also includes a water distribution plate 4 located in the head 101 of the shower head body 1. The water outlet is located on the water distribution plate 4. A water distribution pipe 400 is correspondingly located on the water distribution plate 4. The water distribution pipe 400 is coaxial with the switching pipe. The top of the water distribution pipe 400 is closed and the bottom is open to form a water distribution cavity 40. The lower part of the water distribution pipe 400 extends into the shower head body 1. The upper end of the switching pipe of the handle 102 of the body 1 extends into the water distribution chamber 40 through the bottom opening of the water distribution pipe 400. The water distribution pipe 400 and the water distribution plate 4 share a common wall surface 42. Each water outlet 41 is provided with a corresponding water inlet 411. The water inlet 411 is a through opening provided on the common wall surface 42 to realize the connection between the corresponding water outlet 41 and the water distribution chamber 40. The head 101 of the shower body 1 has water outlet holes 14 that are respectively connected to each water outlet. The water outlet hole corresponding to the spray gun water outlet is the spray gun water spray port.

[0032] The switching pipe is installed in the water inlet 60 and its upper end extends into the water distribution chamber 40. The switching pipe is driven by the push button 2 and can move synchronously with the push button 2. Two sealing structures 30 are provided between the outer wall of the switching pipe and the inner wall of the water distribution chamber 40. The part of the switching pipe located between the two sealing structures 30 is the water outlet section 301. The water outlet section 301 and the inner wall of the water distribution chamber 40 cooperate with the two sealing structures to form an annular closed water outlet chamber 302. The side of the water outlet section 301 is provided with an outlet 3011 for connecting the water outlet chamber 302 and the inner cavity of the switching pipe.

[0033] In this specific embodiment, the blocking arm 309 is disposed on the switching tube.

[0034] In this specific embodiment, the mounting protrusion T1 is set on the back of the water distribution plate 4 and is located between the water distribution plate 4 and the outer shell of the shower body, with space between the two for the movement of the blocking member 8 and the blocking arm 309.

[0035] In this specific embodiment, the height of the inlet 411 along the direction of movement of the push button 2 is greater than or equal to the height of the outlet cavity 302 in that direction. This ensures that the corresponding water outlet mode is accurately used after switching to the correct position.

[0036] In this specific embodiment, the inner diameter of the water distribution cavity 40 is larger than the outer diameter of the switching pipe. The sealing structure 30 includes an annular convex wall 303 protruding from the switching pipe, and an annular recess 3031 recessed on the annular convex wall 303. Two sealing rings 5 ​​are tightly fitted between the two annular recesses 3031 and the inner wall of the water distribution cavity 40. The two annular convex walls 303 are spaced apart, with the outlet section 301 between them. The outer walls of the two annular convex walls 303 and the outlet section 301, together with the inner wall of the water distribution cavity 40, form a closed outlet cavity 302 with the cooperation of the two sealing rings 5. The inner diameter of the water distribution cavity 40 is larger than the outer diameter of the switching pipe, facilitating the formation of an outlet cavity 302 with a certain volume to ensure water supply. The sealing structure 30 is simple in structure and low in cost. Furthermore, the sealing rings 5 ​​provide a certain damping effect on the movement of the switching pipe, improving the operating feel and preventing misoperation.

[0037] In this specific embodiment, in order to further improve the sealing performance and ensure that there is no internal leakage of water flow, an upper sealing structure 305 is provided between the upper end of the switching pipe and the water distribution chamber 40, a lower sealing structure 306 is provided between the upper end of the switching pipe and the water inlet 60, and an auxiliary sealing structure 307 is provided between the upper end of the switching pipe and the water inlet 60. The auxiliary sealing structure 307 is located between the lower sealing structure 306 and the sealing structure 30 located below.

[0038] In this specific embodiment, the upper sealing structure 305, the lower sealing structure 306, and the auxiliary sealing structure 307 are identical in structure to the sealing structure 30 described above. The structure is simple and easy to manufacture.

[0039] In this specific embodiment, the handle 102 of the shower head body is provided with a water inlet pipe 6, and the water inlet passage 60 is the inner cavity of the water inlet pipe 6. The water inlet pipe 6 and the water distribution pipe 400 are spaced apart. The handle 102 is provided with a through guide groove 15 for the push button 2 to move. The push button 2 includes an operating part 21 and a guide part 22. The operating part 21 is located outside the handle 102, and the guide part 22 extends through the guide groove 15 into the space between the water inlet pipe 6 and the water distribution pipe 400 and is fixedly connected to the switching pipe. Water flows directly from the water inlet pipe 6 into the water outlet chamber 302 through the switching pipe. The spaced arrangement of the water inlet pipe 6 and the water distribution pipe 400 does not affect the direct fixed connection between the guide part 22 of the push button 2 and the switching pipe, nor does the pushing of the push button 2 drive the movement of the switching pipe.

[0040] In this specific embodiment, a cover plate 9 is provided inside the handle 102 to cover the guide groove 15, and the cover plate 9 is fixedly connected to the switching tube to ensure aesthetics.

[0041] In practical use, the push button 2 drives the switching tube to move along the central axis of the handle 102 and push it to the corresponding position, so that the water outlet chamber 302 is connected to the corresponding water inlet 411 on one of the water outlet channels 41. Water flows from the water inlet 60 into the switching tube, enters the water outlet chamber 302 through the water outlet 3011 on the switching tube, enters the corresponding water outlet channel 41 through the connected water inlet 411, and then forms the outward shower water outlet from the water outlet hole 14 connected to the water outlet channel 41.
