Description

Technical Field

[0001] This invention relates to the field of shower heads, and more specifically to a spray gun shower head. Background Technology

[0002] Currently, showerheads are mainly used for bathing, but in some situations, they are also used to rinse away stains. The rinsing water spray from these stain-rinsing spray guns generally falls into two categories: one is high-pressure jet spray, which has the advantage of strong water force and easily cleans stubborn stains, but its coverage area is small, making it difficult to operate and less efficient when cleaning large areas of stains; the other is blade-shaped spray, which has a large coverage area and is suitable for cleaning large areas, but its cleaning ability for stubborn stains is weaker.

[0003] In related technologies, showerheads typically feature buttons and toggle switches. Buttons switch between shower and rinsing water sprays, while toggle switches the rinsing water spray state when it's already on. This means that switching the water spray shape and the rinsing water state requires separate operating components, which is inconvenient. Furthermore, current showerheads often only offer one type of rinsing water spray: a high-pressure jet or a blade-like spray, making it impossible to adjust the spray shape as needed.

[0004] Therefore, before implementing the technical solution of this invention, the inventors discovered the following technical problems with spray guns and shower heads in related technologies:

[0005] The spray guns and showerheads in the relevant technologies are not convenient enough in terms of water spray control, and it is difficult to switch the shape of the rinsing water spray, resulting in poor applicability. Summary of the Invention

[0006] (a) Technical problems to be solved

[0007] This invention provides a spray gun shower head that at least solves the problems of inconvenient water spray control and difficulty in fine-tuning the water spray shape in existing spray gun shower heads, thereby improving the applicability of the product.

[0008] (II) Technical Solution

[0009] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0010] A spray gun shower head, comprising:

[0011] The main body is equipped with a water inlet and a shower water outlet;

[0012] A water path switching mechanism is installed inside the main body, including a water distribution plate connected to the water inlet and a swing rod connected to the water distribution plate.

[0017] In some embodiments, the movable cover is a sliding cover, and the flushing switching mechanism further includes a linkage and a spring. The linkage is movably disposed within the main body and connected to the push-twist mechanism. The sliding cover is connected to the linkage and has a flushing water spray outlet. The flushing water spray outlet includes a tapered section whose diameter gradually decreases along the water outlet direction. The spring is located between the flushing water outlet and the tapered section. The spring includes a fixed end and a movable end. The fixed end is fixed relative to the main body, and the movable end is located inside the tapered section. There are at least two springs, and a water outlet gap is formed between the springs along the water outlet direction.

[0018] In some embodiments, the flushing switching mechanism further includes a limiting block fixed to the water distribution plate. The limiting block has a guide groove and includes a limiting protrusion located in the guide groove. The push rod is slidably disposed in the guide groove and has a limiting groove that slides with the limiting protrusion.

[0019] In some embodiments, the flushing switching mechanism further includes a guide shaft and a linear spring. The guide shaft is fixed on the water distribution plate or the main body and slides through the movable cover along the direction of the push rod. The linear spring is sleeved on the guide shaft, with one end abutting against the sliding cover and the other end abutting against the water distribution plate. The compression direction of the linear spring is parallel to the water outlet direction of the flushing outlet.

[0020] In some embodiments, the sliding cover includes a crossbar connected to a push rod, at least two longitudinal bars connected to the crossbar, and an end cap connected to the longitudinal bars; the crossbar has a through hole for a guide shaft to pass through; a clearance space is formed between the longitudinal bars; the water distribution plate includes a protrusion located in the clearance space, and the guide shaft and the flushing water outlet are located at opposite ends of the protrusion; the flushing water outlet is located on the end cap.

[0021] In some embodiments, the water distribution plate is provided with a water distribution cavity communicating with the water inlet, the bathing water path and the rinsing water path, and includes a plug plate located in the water distribution cavity, a rotating shaft connected to the plug plate, a compression spring located in the water distribution cavity and pushing the plug plate to block the bathing water path or the rinsing water path, and a cover for the water distribution cavity; one end of the rotating shaft extends out of the water distribution cavity and is connected to the swing rod.

[0022] In some embodiments, the body includes a faceplate rotatably connected to a water distribution plate. The faceplate includes a toggle switch and has at least two flow channels. A shower spray outlet communicates with the flow channels, and each flow channel has a water inlet. The water distribution plate has a connecting hole that communicates with the shower outlet. The shower head also includes a shower switching mechanism, which includes a pressure block and a spring disposed between the pressure block and the water distribution plate. The pressure block is in sealing contact with the faceplate and has a water passage hole located on the rotation path of the water inlet.

[0023] In some embodiments, the shower switching mechanism further includes a positioning bead and a pre-tensioning spring. The water distribution plate is provided with a mounting hole, the positioning bead is movably disposed in the mounting hole, and the pre-tensioning spring is connected between the water distribution plate and the positioning bead. The face cover is provided with a positioning hole adapted to the positioning bead, and the rotation path of the positioning bead toward the positioning hole is arranged.

[0024] In some embodiments, the swing rod is located between the push rod and the water distribution plate and has a swing hole. The push rod has a clearance groove for the swing rod and is connected to the swing hole by a pin.

[0025] (III) Beneficial Effects

[0026] Compared with the prior art, the spray gun shower head provided by the present invention has the following beneficial effects:

[0027] When this shower head is in operation, water flows into the water distribution plate through the inlet of the main body. When the push knob is in the shower position, the water distribution plate is switched to the shower water path by the lever. The water flows from the shower water path through the shower outlet and finally sprays out from the shower spray outlet, forming shower spray. When the push knob is in the rinse position, the lever switches the water distribution plate to the rinse water path. The water flows from the rinse water path through the rinse water outlet and sprays out from the rinse spray outlet, forming rinse spray. After the push knob is in the rinse position, the user can continue to push the knob to switch between different spray positions and move the movable cover to change the opening angle of the rinse spray outlet, thereby changing the shape of the rinse spray. It can be seen that the shower head of this invention can switch between shower spray and rinse spray by pushing the knob, and can also adjust the shape of the rinse spray. It is convenient to use and meets the user's needs for using the shower head in different scenarios. Attached Figure Description

[0049] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0050] Shower guns typically feature buttons and toggle switches. Buttons toggle between shower and rinsing water sprays, while toggle switches between different rinsing water spray patterns when the rinsing water is on. This means switching between different spray patterns and rinsing water spray patterns requires separate controls, which is inconvenient. Furthermore, current shower guns often only offer one type of rinsing water spray: a high-pressure jet or a blade-like spray, making it impossible to adjust the spray pattern as needed.

[0051] To address the aforementioned technical problems, the present invention provides the following embodiments:

[0052] Example 1:

[0053] Please see Figure 1 , Figure 2 , Figure 3 As shown, Figure 1 This is a perspective view of the spray gun shower head in Example 1. Figure 2 This is an exploded view of the spray gun shower head in Example 1. Figure 3 This is a cross-sectional view of the spray gun shower head in the shower position in Example 1.

[0054] This embodiment provides a spray gun shower head, including: a body 1, a water path switching mechanism 2, and a rinsing switching mechanism 3.

[0055] The main body 1 has a water inlet 11 and a shower water outlet 12.

[0056] The aforementioned body 1 is the housing of the spray gun shower head, which may include a handle, a face cover 10, etc. The inlet 11 is used to connect water flow into the spray gun shower head, the shower water outlet 12 is used to make the water flow form shower water spray, and the clearance opening 13 is used to make way for the cleaning water spray.

[0057] Combination Figures 4 to 9 As shown, Figure 4 This is a cross-sectional view of the blade-shaped water spray formed by the spray gun head at the rinsing position in Example 1. Figure 5 This is a cross-sectional view of the water jet formed by the spray gun in the rinsing position in Example 1. Figure 6 This is a front perspective view of the water path switching mechanism and the flushing switching mechanism in Example 1. Figure 7 This is a rear perspective view of the water path switching mechanism and the flushing switching mechanism in Example 1. Figure 8 This is a top view of the water path switching mechanism and the flushing switching mechanism in Example 1. Figure 9 This is a schematic diagram of the water distribution plate near the top cover in Example 1.

[0058] The water path switching mechanism 2 is installed inside the main body 1 and includes a water distribution plate 21 connected to the water inlet 11 and a swing rod 22 connected to the water distribution plate 21. The water distribution plate 21 is provided with a bathing water path 201, a rinsing water path 202, a bathing water outlet 203 connected to the bathing water path 201 and a rinsing water outlet 204 connected to the rinsing water path 202. The bathing water outlet 203 is connected to the bathing water spray outlet 12. The swing rod 22 is configured to switch the bathing water path 201 and the rinsing water path 202 of the water distribution plate 21.

[0059] The aforementioned water path switching mechanism 2 is used to switch the water path of the spray gun shower head; wherein, the water distribution plate 21 can be a rotating water distribution plate 21 or a pushing water distribution plate 21, and can be fixed to the inside of the body 1 by means of a snap-fit ​​structure or screw connection; the swing rod 22 controls the water path switching component of the water distribution plate 21 by connecting with the water distribution plate 21, thereby realizing the water path switching of the water distribution plate 21; the shower water path 201 is used to supply water to the shower outlet 203, and then to the shower water spray outlet 12; the rinsing water path 202 is used to supply water to the rinsing outlet 204.

[0060] The rinsing switching mechanism 3 includes a push knob 31, a linkage 32, a movable cover 33, and a spring piece 34. The push knob 31 is movably disposed between the shower position and the rinsing position relative to the main body 1 and is connected to the swing arm 22. The linkage 32 can be a push rod, a hinge rod, etc. In this embodiment, the linkage 32 is a push rod. The linkage 32 is slidably disposed inside the main body 1 and connected to the push knob 31. The movable cover 33 is connected to the linkage 32. A rinsing water outlet 300 is provided between the movable cover 33 and the main body 1. In this embodiment, the rinsing water outlet 300 can also be equivalently opened on the movable cover 33. On the movable cover 33, in this embodiment the movable cover 33 is a sliding cover, the flushing outlet 204 is set toward the flushing water outlet 300, the flushing water outlet 300 includes a tapered section 301 whose diameter gradually decreases along the water outlet direction of the flushing outlet 204, the spring piece 34 is located between the flushing outlet 204 and the tapered section 301, the spring piece 34 includes a fixed end fixed relative to the body 1 and a movable end located inside the tapered section 301, the number of spring pieces 34 is at least two pieces, and a water outlet gap is formed between the spring pieces 34 along the water outlet direction of the flushing outlet 204.

[0061] The aforementioned flushing switching mechanism 3 is used to adjust the shape of the flushing water spray. The push knob 31 slides relative to the main body 1 when pushed by the user. The main body 1 can be provided with a corresponding groove to slide and install the push knob 31. The push knob 31 slides and is linked to the swing arm 22 and the linkage 32 to move simultaneously. When the linkage 32 moves, the movable cover 33 moves relative to the spring piece 34 and contacts the movable end of the spring piece 34 through the tapered section 301 of the flushing water spray outlet 300, squeezing the movable end of the spring piece 34 inward, thereby controlling the spacing of the movable end of the spring piece 34. The movable cover 33 can be located inside the clearance opening 13. The spacing of the spring piece 34, i.e. the water outlet gap, gradually increases or decreases during the sliding of the movable cover 33. The shape of the water sprayed from the flushing water spray outlet 300 changes between two extreme states, such as changing between a blade shape and a water column shape.

[0062] When the push knob 31 is in the shower position, the water distribution plate 21 switches to the shower water path 201; when the push knob 31 is in the rinse position, the water distribution plate 21 switches to the rinse water path 202.

[0063] When the spray gun shower head of the above technical solution is working, water flows into the water distribution plate 21 from the inlet 11 of the main body 1. When the push knob 31 is in the shower position, the water distribution plate 21 switches to the shower water path 201. The water flows from the shower water path 201 through the shower outlet 203 and finally flows out from the shower water spray outlet 12, forming a shower water spray. When the push knob 31 is in the rinsing position, the swing arm 22 switches the water distribution plate 21 to the rinsing water path 202. The water flows through the rinsing water path 202 and sprays out from the rinsing outlet 204. The sprayed water flows through the water outlet gap formed between the spring pieces 34 to form a rinsing water spray. After the push knob 31 is in the rinsing position, the user can push the push knob 31 to make the push knob 31 drive the movable cover 33 to slide. During the sliding process, the movable cover 33 contacts the spring 34 through the tapered section 301 of the flushing water outlet 300, thereby adjusting the size of the water outlet gap, i.e., the opening angle of the flushing water outlet 300. When the push knob 31 is at the front end of the flushing position, the water outlet gap is squeezed by the flushing water outlet 300, resulting in a smaller opening angle and the flushing water droplets are blade-shaped. As the push knob 31 is pushed towards the rear end of the flushing position, the diameter of the water outlet gap gradually increases, and the flushing water droplets gradually become water column-shaped. In this way, the fine adjustment and stepless adjustment of the flushing water droplets can be achieved. The flushing water droplets maximize the coverage area while meeting the flushing water pressure, satisfying the user's needs for using the spray gun shower in different scenarios.

[0064] See Figure 6 and Figure 7 As shown, in order to guide the sliding of the linkage 32 and limit its travel, the flushing switching mechanism 3 also includes a limiting block 35 fixed to the water distribution plate 21 by screws or other means. The limiting block 35 has a guide groove 302 on the side near the water distribution plate 21 and includes a limiting protrusion 303 located within the guide groove 302. The linkage 32 is slidably disposed within the guide groove 302 and has a limiting groove 304 that slides with the limiting protrusion 303. Thus, the guide groove 302 can limit the movement of the linkage 32, and the limiting protrusion 303 restricts the travel of the linkage 32, thereby making the sliding of the linkage 32 more stable.

[0065] Combination Figure 2 and Figure 3 As shown, to achieve automatic reset of the flushing switching mechanism 3, the flushing switching mechanism 3 includes a guide shaft 36, which is fixed to the water distribution plate 21 or the main body 1. The guide shaft 36 slides along the sliding direction of the movable cover 33 and passes through the movable cover 33. The flushing switching mechanism 3 also includes a linear spring 37, which is sleeved on the guide shaft 36, with one end abutting against the movable cover 33 and the other end abutting against the water distribution plate 21. The compression direction of the linear spring 37 is parallel to the water outlet direction of the flushing outlet 204. In this way, when the movable cover 33 slides, it is guided by the guide shaft 36 and compresses the linear spring 37. After compression, the linear spring 37 provides force to automatically reset the movable cover 33, eliminating the need for manual reset operation and making it more convenient to use.

[0066] See Figure 6 As shown, the movable cover 33 further includes a crossbar 331 connected to the linkage 32, at least two longitudinal bars 332 connected to the crossbar 331, and an end cap 333 connected to the longitudinal bars 332; the crossbar 331 has a through hole for the guide shaft 36 to pass through; a clearance space is formed between the longitudinal bars 332; the water distribution plate 21 includes a protrusion located in the clearance space, and the guide shaft 36 and the flushing outlet 204 are located at opposite ends of the protrusion; the flushing water outlet 300 is located on the end cap 333. In this way, the linkage 32 sequentially pushes the crossbar 331, the longitudinal bars 332, and the end cap 333 to move, and the clearance space prevents the crossbar 331 from colliding with the protrusion during movement and reduces the weight of the components.

[0067] To avoid interference between the swing arm 22 and the linkage 32, and to minimize their space occupation, the swing arm 22 is located between the linkage 32 and the water distribution plate 21, and has a swing hole 220. The linkage 32 has a clearance groove 320 for the swing arm 22, and is connected to the swing hole 220 by a pin. In this way, the swing arm 22 can move within the clearance groove 320, avoiding arc interference and reducing space occupation.

[0068] See Figure 10 and Figure 11 As shown, Figure 10 This is a cross-sectional perspective view of the water distribution plate in Example 1. Figure 11 This is a schematic diagram of the installation structure of the faceplate near the water distribution plate in Embodiment 1. In one embodiment of the water distribution plate 21, the water distribution plate 21 is provided with a water distribution cavity 210 communicating with the water inlet 11, the shower water passage 201 and the rinse water passage 202, and includes a plug 211 located in the water distribution cavity 210, a rotating shaft 212 connected to the plug 211, a compression spring 213 located in the water distribution cavity 210 and pushing the plug 211 to block the shower water passage 201 or the rinse water passage 202, and a cover 214 of the water distribution cavity 210; one end of the rotating shaft 212 extends out of the water distribution cavity 210 and is connected to the swing rod 22. In this embodiment, the rocker arm 22 controls the rotation of the rotating shaft 212, which in turn controls the rotation of the plug 211. Under the action of the compression spring 213, the plug 211 blocks the bathing water path 201 or the rinsing water path 202, thereby achieving water path switching. This water distribution plate 21 has a simple and reliable structure; the switching of different water paths can be controlled by rotating the rocker arm 22, making operation convenient. It is understood that in other embodiments, the water distribution plate 21 can also be a push-type water distribution plate, where the rocker arm 22 pushes the water path switching component of the water distribution plate to achieve water path switching.

[0069] See Figure 11 and Figure 12 As shown, Figure 12This is a schematic diagram of the shower switching mechanism in Embodiment 1. To control the shape of the shower spray, the main body 1 includes a face cover 10, which comprises two separable parts. The face cover 10 is rotatably connected to the water distribution plate 21 via a connecting shaft 18. The face cover 10 includes a lever 14 for controlling its own rotation. The face cover 10 has at least two flow channels 15, each flow channel 15 having a certain number and shape of shower spray outlets 12. The shower spray outlets 12 communicate with the flow channels 15, and each flow channel 15 has a water inlet 16. The water distribution plate 21 has a connecting hole 2. 05. The connecting hole 205 is connected to the shower outlet 203; the spray gun shower also includes a shower switching mechanism 4. The shower switching mechanism 4 includes a pressure block 41 movably disposed in the connecting hole 205 and a pressure spring 42 disposed between the pressure block 41 and the water distribution plate 21. The pressure spring 42 makes the pressure block 41 and the face cover 10 in sealed contact. The pressure block 41 is provided with a water passage hole 410. The water passage hole 410 is located on the rotation path of the water inlet 16, so that the face cover 10 can open and close the water passage hole 410 by rotating. When using this shower head, the water flows sequentially from the shower outlet 203, connecting hole 205, water passage hole 410, and inlet 16 to the flow channel 15, and then flows out from the corresponding shower outlet 12 in the flow channel 15. Because the number, shape, and / or size of the shower outlets 12 in each flow channel 15 are different, different shower spray patterns are formed. Users can rotate the faceplate 10 by turning the knob 14 to connect the inlet 16 of different flow channels 15 with the corresponding water passage hole 410, thus obtaining shower spray patterns of different shapes. In this way, the shower head not only allows for adjustable rinsing spray patterns but also allows for adjustable shower spray patterns to meet different user needs, further improving the product's applicability.

[0070] To facilitate the positioning of the water inlet 16 and the water outlet 410 when the faceplate rotates, the shower switching mechanism 4 also includes a positioning bead 43 and a pre-tensioning spring 44. The water distribution plate 21 has a mounting hole 206, and the positioning bead 43 is movably disposed within the mounting hole 206. The pre-tensioning spring 44 connects the water distribution plate 21 and the positioning bead 43. The faceplate 10 has a positioning hole 17 that matches the positioning bead 43, and the rotation path of the positioning bead 43 is set towards the positioning hole 17. The number of positioning holes 17 can be set according to the shape and number of shower water sprays and the number of flow channels 15. During the rotation of the faceplate 10, when the water inlet 16 and the water outlet 410 are aligned, the positioning bead 43 is aligned with the positioning hole 17 and is engaged in the positioning hole 17 under the push of the pre-tensioning spring 44, thus creating a sense of position and facilitating the judgment of whether the switching operation is complete. As the faceplate 10 continues to rotate, the positioning bead 43 moves out of the positioning hole 17 through the balancing inclined plane, without interfering with the normal rotation of the faceplate 10. The cover 10 can also be provided with a limiting protrusion 19 to block the positioning bead 43, so that the positioning bead 43 moves within a certain range. It can be understood that the shower switching mechanism 4 can also be applied to the movable cover 33 or the linkage 32. For example, the positioning bead 43 and the pre-tension spring 44 can be installed on the linkage 32, and multiple corresponding positioning holes 17 can be opened on the body 1 or the water distribution plate 21. The positioning holes 17 are located on the moving path of the positioning bead 43 and cooperate with the positioning bead 43 for positioning during the sliding process of the cover, so as to achieve the effect of shifting.

[0073] This embodiment provides a spray gun shower head, which differs from Embodiment 1 in that the push knob 31 and the movable cover 33 work together to change the opening angle of the rinsing water outlet 300, as detailed below:

[0074] The movable cover 33 of the spray gun shower head is a rotating cover. The rotating cover is rotatably disposed inside the body 1 and forms a rinsing water outlet 300 between it and the body 1. The rinsing switching mechanism 3 includes a linkage 32 connected to the push knob 31. The linkage 32 is configured to drive the rotating cover to rotate relative to the body 1 and change the opening angle of the rinsing water outlet 300.

[0075] In one embodiment where the rotating cover is rotatably disposed within the body 1, the movable cover 33 is rotatably connected to the body 1 via a rotating shaft 334. The rotating shaft 334 can be integrally formed on the movable cover 33. The body 1 has a shaft hole for the rotating shaft 334. The movable cover 33 forms a first rotating end and a second rotating end on both sides of the rotating shaft 334. A rinsing water outlet 300 is formed between the first rotating end and the clearance opening 13 of the body 1. The second rotating end has an inclined surface 335 facing the linkage 32. This inclined surface 335 is on the movement path of the linkage 32 and is configured to be pushed by the linkage 32 to drive the movable cover 33 to rotate. It is understood that in some embodiments, the rotating cover can also be rotatably disposed within the body 1 by being rotatably connected to the water distribution plate 21.

[0076] In order to achieve automatic reset of the flushing switching mechanism 3, the flushing switching mechanism 3 can also be equipped with a torsion spring 38. The two ends of the torsion spring 38 abut against the body 1 and the rotating cover respectively, and can be sleeved on the rotating shaft 334 or other shafts. The torsion spring 38 provides the torque for the rotating cover to rotate to the initial position.

[0077] In one embodiment of the linkage 32, the linkage 32 can be a push rod. In this embodiment, the push rod is driven by the push torque 31 and pushes the inclined surface 335 to rotate the movable cover 33 around the rotating shaft 334, thereby increasing or decreasing the opening angle of the rinsing water outlet 300, and thus changing the shape of the rinsing water. Specifically, when the push torque 31 is at the water spray switching position at the front of the rinsing position, the opening angle of the rinsing water outlet 300 is small, and the rinsing water is blade-shaped. As the push torque 31 is pushed towards the water spray switching position at the rear of the rinsing position, the diameter of the water outlet gap gradually increases, and the rinsing water gradually becomes a water column. In this way, the spray gun shower head of this embodiment can achieve fine adjustment and stepless adjustment of the rinsing water, thereby maximizing the coverage area of ​​the rinsing water while meeting the rinsing water pressure, and meeting the user's needs for the spray gun shower head in different scenarios.

[0078] It is understood that in some embodiments, the linkage 32 may also be a connecting rod or connecting rod assembly hinged to the push knob 31 and the movable cover 33. The connecting rod may be rotatably connected to the body 1 or the water distribution plate 2. During operation, the push knob 31 drives the movable cover 33 to rotate through the connecting rod or connecting rod assembly.

[0079] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
