Description

Technical Field

[0001] The utility model relates to the technical field of bathroom products, in particular to a spray gun shower head with an anti-misspraying structure. Background Art

[0002] Conventional showerheads are typically installed in bathrooms or toilets for showering, but the water's limited spray force makes it difficult to effectively flush bathroom floors, windows, toilets, and other surfaces. Consequently, more and more showerheads are equipped with separate spray guns to meet these flushing requirements. However, the inclusion of spray guns complicates the showerhead's internal structure and increases costs. Furthermore, for bathrooms that already have showers or lack the space for a separate spray gun, flushing with a spray gun is difficult. Consequently, more and more showerheads are equipped with spray guns, both to save costs and to facilitate aftermarket use. These spray gun showerheads typically use a switch valve to switch between spray gun and shower water. Currently, the water outlet of most spray gun showerheads is located at the front of the showerhead. If the high-pressure spray gun is accidentally activated, it can spray onto the ceiling, electrical outlets, or even into the face, causing unnecessary discomfort or even physical injury.

[0003] Therefore, Chinese patent CN220991322 proposes an anti-accidental spraying structure for a spray gun shower head. In this structure, the switch of the switching valve needs to be pressed and the nozzle of the spray gun is pointed downwards, and the channel of the spray gun water will be opened. During use, it is found that the spray gun water also needs to be pointed upwards or tilted to spray walls, glass doors, etc. Therefore, the anti-accidental spraying structure is inconvenient for users to use and the user experience is not good.

[0043] Example

[0044] Combine Figures 1 to 9 , this embodiment provides a spray gun shower head with an anti-misspraying structure, comprising a body 1, a switching valve 2 and a water stop valve 3. A water outlet assembly 4 is provided on the front of the body 1, and a spray gun water outlet 11 is provided on the side or back of the body 1. The interior of the body 1 is provided with a water inlet channel 61, a first water outlet channel 62 and a second water outlet channel 63. By pressing a button 5 exposed on the body 1, the switching valve 2 is driven to switch between a first position and a second position, and the corresponding water inlet channel 61 is connected to the first water outlet channel 62 or the second water outlet channel 63; wherein the first water outlet channel 62 is used to communicate with the water outlet assembly 4, and the second water outlet channel 63 is configured to control the connection and disconnection with the spray gun water outlet 11 through the water stop valve 3. The water stop valve 3 is configured to drive the water outlet assembly 4 to rotate in an operative manner to approach or move away from the trigger part 422 on the water outlet assembly 4, thereby controlling the opening and closing of the water stop valve 3.

[0045] For example, when the switching valve 2 is in the first position, the water inlet channel is connected to the first water outlet channel 62. At this time, rotating the water outlet component 4 can only realize the switching of the shower water pattern; pressing the button 5 to put the switching valve 2 in the second position, at this time the water inlet channel is connected to the second water outlet channel 63, and then rotating the trigger part 422 of the water outlet component 4 to abut against the water stop valve 3, so that the second water outlet channel 63 can be connected to the spray gun water outlet 11, and the corresponding spray gun water outlet 11 sprays high-pressure water.

[0046] It should be noted that in this embodiment, when the water outlet 11 of the spray gun is discharged, it is necessary to press the button 5 to select the connection between the water inlet channel 61 and the second water outlet channel 63. At the same time, it is necessary to drive the water outlet component 4 to rotate so that the trigger part 422 opens the water stop valve 3 to realize the discharge of water from the water outlet 11 of the spray gun. Among them, pressing the button 5 and rotating the water outlet component 4 are both indispensable. This double linkage structure can prevent the user from accidentally touching the button 5 to cause water to discharge from the water outlet 11 of the spray gun, thereby preventing high-pressure water from being sprayed onto the ceiling, power sockets or body parts. It can also act as a child lock when children use the shower head to prevent children from being injured by misoperation. In addition, compared with the existing technology, when the water outlet 11 of the spray gun is discharged, its direction will not be restricted and water can be sprayed toward any position, which is convenient for users to use and improves the user experience.

[0047] In a preferred embodiment, the water outlet assembly 4 includes a water outlet cover 41 and a water diversion tray 42. The water outlet cover 41 is provided with a plurality of water outlet nozzles, and the water diversion tray 42 is provided with a plurality of water diversion ports 421 corresponding to each water outlet nozzle. By driving the water outlet cover 41 to rotate, the water inlet connected to the first water outlet channel 62 is connected to at least one of the water diversion ports 421. For example, each water diversion port 421 corresponds to a different water outlet nozzle to form a water path. The water inlet is equipped with a cat's eye pad 43, which is provided with a water inlet hole. When the water inlet hole is connected to one of the water diversion ports 421, one type of water spray is produced, and when it is connected to two water diversion ports 421, two types of water spray are produced. By rotating the water outlet cover 41, the water diversion tray 42 is synchronously rotated relative to the water inlet, thereby switching the shower water spray pattern to meet the different needs of users.

[0048] Preferably, the water distribution tray 42 is provided with a pause water outlet. When the pause water outlet is connected to the water inlet, the water outlet cover 41 is in a pause water state. The pause water state is a state where the water flow is stopped or dripping. This facilitates the user to apply shower gel or shampoo without having to turn the shower faucet on and off to pause the water flow, thereby avoiding changes in water temperature caused by adjusting the shower faucet. The structure of the pause water outlet nozzle is prior art and will not be described in detail here.

[0049] Preferably, when the water outlet cover 41 is in the water-pausing state, the trigger portion 422 abuts against the water stop valve 3 to open the water stop valve 3. It is easy to understand that in this embodiment, when the water inlet channel 61 is connected to the first water outlet channel 62, the water outlet cover 41 can be rotated to connect the water-pausing outlet 421 to the water inlet, thereby realizing the water-pausing function; when the water inlet channel 61 is connected to the second water outlet channel 63, the water outlet 11 can be realized by rotating the water outlet cover 41 to the same position and pressing the button 5, that is, the same position realizes two functions, which can save structural space and avoid the structural space being too large and affecting the appearance of the shower head.

[0050] Based on the above embodiment, in an optional embodiment of the present invention, the water diversion plate 42 is provided with a groove 423 along the circumference, and the trigger portion 422 is configured as an inclined rib disposed along the groove 423. Specifically, the water stop valve 3 includes a water stop shaft 31 and an elastic member 32 sleeved on the water stop shaft 31. The water stop shaft 31 is configured to abut and seal against the outlet of the second water outlet channel 63 under the action of the elastic member 32. A toggle portion 411 is provided on the water outlet cover 41. The water outlet cover 41 and the water diversion plate 42 are fixed together by fasteners or welding to form a water outlet assembly 4. A rotation hole is provided through the center of the water outlet assembly 4. The rotation hole is configured to connect to the central axis of the body 1 via a screw, thereby enabling the water outlet assembly 4 to rotate when the user manually toggles the toggle portion 411. During the rotation of the water diversion plate 42, the end of the water stop shaft 31 is retained within the groove 423 to prevent shaking. The trigger portion 422 is configured as a circumferentially inclined rib, allowing the showerhead to smoothly rotate onto the rib during rotation. When the waterstop shaft 31 abuts the rib, it is lifted and the sealing portion 311 moves upward, connecting the outlet of the second water outlet channel 63 to the spray gun water outlet 11. When the waterstop shaft 31 rotates to a non-ribbed position, it returns to its original position under the action of the elastic member 32 (e.g., a spring), and the sealing portion 311 abuts and seals the outlet of the second water outlet channel 63. Preferably, a sealing member 33 is disposed on the outer sleeve of the waterstop shaft 31 to prevent water from entering the groove 423.

[0051] In another embodiment, a water diversion seat 6 is further included, on which a water inlet channel 61, a first water outlet channel 62 and a second water outlet channel 63 are formed. The water inlet channel 61 is connected to the water channel 7, the first water outlet channel 62 is arranged along the middle of the water diversion seat 6, and the second water outlet channel 63 is arranged on the outer periphery of the first water outlet channel 62. The water diversion seat 6 is provided with a first installation cavity 64 for installing the switching valve 2 and a second installation cavity 65 for installing the water stop valve 3, and a spray gun water outlet nozzle 66 is installed at the other end relative to the water inlet channel 61. The spray gun water outlet nozzle 66 is inserted into the spray gun water outlet 11. The arrangement of the water diversion seat 6 can make the structure more compact. Preferably, the water diversion seat 6 is integrally formed by injection molding, which can reduce parts and assembly steps, thereby simplifying the internal waterway and reducing costs.

[0052] In other embodiments, the button 5 is disposed on the back side of the body 1 and is provided with a hinge hole 51 and a stop hole 52. The hinge hole 51 is configured to be hingedly connected to the hinge shaft 671 on the water diversion seat 6, and the stop hole 52 is configured to be adapted to connect with the valve stem 21 of the switching valve 2. For example, the hinge hole 51 is provided in the middle of the button 5, the water diversion seat 6 includes a sealing cover 67 disposed on its top, and the sealing cover 67 is provided with a hinge shaft 671. The stop hole 52 is provided at the front end of the button 5. When the rear end of the button 5 is pressed, the front end of the button 5 is tilted, allowing the valve stem 21 connected to the stop hole 52 to be lifted, thereby connecting the water inlet channel 61 to the second water outlet channel 63. When the front end of the button 5 is pressed or the rear end of the button 5 is released, the valve stem 21 can be reset by the action of a reset spring. Therefore, the default water outlet is the first water outlet channel 62, and only when the rear end of the button 5 is pressed will the second water outlet channel 63 be connected to the water inlet channel 61 to further prevent misoperation. Preferably, the button 5 is provided with anti-slip grooves on the surface to facilitate the user's pressing operation and avoid the situation where the button 5 cannot be pressed when the hands are wet and slippery.

[0053] In other embodiments, a shift member 8 is provided, and a shift hole 424 is provided on the water distribution plate 42. The shift member 8 is movably engaged with the shift hole 424. For example, the shift member 8 includes a spring and a spring. The spring is movably engaged with the shift hole 424 under the action of the spring. When the water outlet assembly 4 rotates, the spring slides out of one shift hole 424 and falls into another shift hole 424, emitting a shift sound. This improves the user's feel when switching gears, and the shift sound allows the user to easily determine whether the gear has been switched.

[0054] The above are only preferred implementations of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention fall within the protection scope of the present invention.
