A handheld shower head

Abstract

The present application discloses a handheld shower head, which includes a fixing component, a rotating component and a first spring. The fixing component is provided with a water inlet channel and a first water outlet channel for spraying water. The rotating component is rotatably connected to the fixing component and is provided with a water passing channel and a second water outlet channel. The first spring is disposed between the fixing component and the rotating component. When the rotating component rotates to a first position, the water passing channel communicates with the water inlet channel and the first water outlet channel, and the first spring is elastically deformed. When the rotating component is released from the first position, the first spring elastically recovers to drive the rotating component to rotate to a second position, at which time the second water outlet channel communicates with the water inlet channel. When the above-mentioned handheld shower head starts to be used each time, it can avoid the state of water flowing out from the first water outlet channel.

Description

Technical Field

[0001] This application relates to the field of water outlet devices, and particularly to a handheld shower head. Background Art

[0002] In the prior art, handheld shower heads are mainly used for gardening and showering. However, whether for gardening or showering, a jet water outlet mode with a relatively large water flow rate and a longer jet distance and a spray water outlet mode with a relatively small water flow rate and a larger coverage area are required. In a shower room, the spray water outlet mode is used to wash the body because the water flow is gentle, while the jet water outlet mode is mainly used to clean the shower room because of the large water impact force.

[0003] In order to combine the two water outlet modes, Chinese Utility Model Patent No. 201320278350.5, which was published on October 2, 2013, provides a handheld shower head that designs two water outlets perpendicular to each other for jet water outlet and spray water outlet respectively. The two water outlet modes are switched by rotating the water outlet face cover relative to the body. However, the above technical solution has three defects: First, after switching to the jet water outlet mode, if the user does not switch the water outlet mode back to the spray water outlet mode and closes the valve for opening and closing the water inlet when cleaning the shower room, then the next time it is used, it is very easy to cause unnecessary splashing due to the large water impact force, and even may cause harm to the body when showering a baby; Second, when switching from the spray water outlet mode to the jet water outlet mode, if the user is not careful and points the jet water outlet upwards or towards the ceiling of the shower room, it is possible to spray water onto the electrical appliances on the shower room wall or ceiling, causing short circuits or damage to the lighting device, thus endangering the safety of the user; Third, the way of realizing the rotational connection between the body and the water outlet face cover of the handheld shower head in the above technical solution results in a longer assembly time and a higher labor cost.

[0016] Compared with the prior art, the above solution has the following beneficial effects:

[0017] The water passing area of the first water outlet is smaller than that of the water inlet, so that the first water outlet has a jet water outlet function. The second water outlet channel is provided with a plurality of second water outlets, so that the second water outlets have a spray water outlet function. The user drives the rotating assembly to rotate relative to the fixed assembly to realize the switching between the first position and the second position, and correspondingly switches the jet water outlet function and the spray water outlet function.

[0018] The first spring is placed between the first abutting surface and the second abutting surface, and elastically deforms when the rotating assembly rotates from the second position to the first position. This requires the user to always apply force to overcome the elastic deformation force of the first spring to keep the handheld shower head in the jet water outlet state; and the first spring elastically recovers when the rotating assembly is released from the first position to drive the rotating assembly to rotate to the second position. This makes it inevitable that once the user stops applying force, the handheld shower head will switch from the jet water outlet state to the spray water outlet state, so that the handheld shower head can avoid being in the jet water outlet state every time it starts to be used.

[0019] The water outlet direction of the first water outlet is perpendicular to the water outlet direction of the second water outlet, which is convenient for the user to hold the handheld shower head easily when cleaning the shower room.

[0020] The chamfer on the shaft hole forces the circlip to deform, enabling the circlip to pass through the shaft hole until it falls into the second annular groove. This realizes the establishment of a rotational connection relationship with axial limit fit between the rotating component and the fixed component with just one plugging operation, making the assembly of the fixed component and the rotating component simpler.

[0021] The circlip is designed as an annular ring with an opening and is wavy when unfolded along the circumferential direction, making the force on the circlip more uniform and the deformation easier during the deformation process along the circumferential direction.

[0022] The blocking member slides or rolls under the action of gravity in the chute and blocks the insertion block from inserting into the chute when it docks at the limiting wall, so that it is impossible to switch from the spray water state to the jet water state when the first water outlet is upward relative to the horizontal plane, improving the safety of the handheld shower head.

[0023] The water outlet seat is provided with a receiving groove for accommodating the first spring, and a receiving groove opening is provided at the other end opposite to the first abutting surface, which can facilitate the reliable state of the first spring during the process of the convex block leaving and entering the receiving groove.

[0024] In the fixed component, the body, the water outlet seat and the fixed seat are all fixedly connected; in the rotating component, the water distribution seat and the water outlet face cover are connected by clamping and the water outlet sleeve is clamped therebetween; therefore, the assembly of both the fixed component and the rotating component is very convenient.

[0025] The second water passing port, the fourth water passing port, the fifth water passing port and the sixth water passing port are all arranged on the outer circumferential surface of the water distribution seat and are arranged along the circumferential direction, enabling the water inlet channel to be sealed conveniently when switching and communicating with the water passing channel, the second water outlet channel, the third water outlet channel and the fourth water outlet channel.

[0026] The positioning pin extends into one of the three positioning pits when the rotating component rotates to the second position, the third position and the fourth position, enabling the user to have a clear sense of gear when switching between three spray water modes. There is no positioning pit when the rotating component rotates to the first position, which is beneficial for the first spring to drive the rotating component to rotate to the second position.

[0054] The technical solutions in the embodiments will be clearly and completely described below in conjunction with the accompanying drawings.

[0055] Figure 1 、 Figure 2 and Figure 3 show the overall structure of the handheld showerhead 10. In this embodiment, the handheld showerhead 10 includes a fixing component 1, a rotating component 2 that rotates around the first axis relative to the fixing component 1, a first spring 3, a snap ring 4, a blocking member 5, a positioning component 6, a first sealing component 7, a second sealing component 8, and a sealing ring 9.

[0056] As Figure 2 and Figure 3 shown, the fixing component 1 includes a main body 11, a water outlet seat 12, and a fixing seat 13. The main body 11 is provided with a handle 111 and a top cover 112 that are integrally connected. The handle 111 is provided with a water inlet channel 14. As Figure 3 shown, at one end of the water inlet channel 14 away from the top cover 112, there is a water inlet 141, and at the other end of the water inlet channel 14, there is a first sealing cavity for accommodating the first sealing component 7. At a position of the top cover 112 away from the handle 111, there is a notch for the water outlet seat 12 to extend out. The lower surface of the top cover 112 extends downward to form a positioning seat 18, and the downward end of the positioning seat 18 is provided with a positioning seat opening. The positioning seat 18 is used for accommodating the positioning component 6.

[0057] As Figure 3 and Figure 4 shown, the water outlet seat 12 is fixedly connected to the top cover 112 and extends out of the notch on the top cover 112. Specifically, in this embodiment, the water outlet seat 12 is snap-connected to the top cover 112. The water outlet seat 12 is provided with a first water outlet channel 15 and a receiving groove 121 extending in the circumferential direction. The first water outlet channel 15 is provided with a first water passing port 151 and a first water outlet 152. The first water passing port 151 is opened on the bottom surface of the water outlet seat 12 away from the top cover 112, and the first water outlet 152 is opened at a position of the water outlet seat 12 away from the handle 111. The water outlet direction of the first water outlet 152 is perpendicular to the first axis, and the water outlet direction of the first water outlet 152 is also in the same plane as the axis of the handle 111. Therefore, it is convenient for the user to hold the handheld showerhead 10 when using the first water outlet 152 to clean the shower room. Of course, in other embodiments, the water outlet direction of the first water outlet 152 may not be perpendicular to the rotation axis. In this embodiment, the water passing area of the first water outlet 152 is smaller than that of the water inlet 141. Therefore, the first water outlet 152 has a function of jetting water. The receiving groove 121 is used for accommodating the first spring 3. One end of the receiving groove 121 close to the first water outlet 152 forms a first abutting surface 122, and the other end of the receiving groove 121 is provided with a receiving groove opening 123.

[0058] As Figure 3 andFigure 5 As shown, the fixed seat 13 is fixedly connected to the top cover 112. Specifically, in this embodiment, the fixed seat 13 is welded to the top cover 112. The fixed seat 13 is provided with a convex shaft 16 and a chute 17. The convex shaft 16 takes the first axis as the axis and extends in the direction away from the top cover 112. A first annular groove 161 and a sealing ring groove 162 are provided on the side wall of the convex shaft 16, and the sealing ring groove 162 is located below the first annular groove 161. The chute 17 is located at a position of the fixed seat 13 away from the first water outlet 152, and the extending direction of the chute 17 is the same as the water outlet direction of the first water outlet 152. A limiting wall 171 is provided at one end of the chute 17 away from the first water outlet 152. Therefore, when the water outlet direction of the first water outlet 152 is upward relative to the horizontal plane, the chute 17 is not parallel to the horizontal plane and the limiting wall 171 is located at the lower end of the two ends of the chute 17. A chute opening 172 is provided on the side wall of the chute 17, and the chute opening 172 is close to the limiting wall 171.

[0059] As Figure 3 and Figure 7 shown, the rotating assembly 2 includes a water distribution seat 21, a water outlet surface cover 22, and a water outlet sleeve 23.

[0060] As Figure 3 , Figure 6 , Figure 7 , Figure 9 and Figure 10As shown in the figure, the water distribution base 21 is rotatably connected to the fixed base 13 about the first axis. The water distribution base 21 is provided with a water passage 24, a second water outlet passage 25, a third water outlet passage 26, and a fourth water outlet passage 27. The water passage 24 is provided with a second water inlet 241 and a third water inlet 242. The second water outlet passage 25 is provided with a fourth water inlet 251 and a plurality of second water outlets 252. The third water outlet passage 26 is provided with a fifth water inlet 261 and a plurality of third water outlets 262. The fourth water outlet passage 27 is provided with a sixth water inlet 271 and a plurality of fourth water outlets 272. Among them, the second water inlet 241, the fourth water inlet 251, the fifth water inlet 261, and the sixth water inlet 271 are all arranged on the outer circumferential surface of the water distribution base 21 and are arranged along the circumferential direction, which is convenient for sealing connection with the water inlet passage 14. The third water inlet 242 is arranged on the end surface of the water distribution base 21 facing the water outlet base 12, and a second sealing cavity is formed therein for accommodating the second sealing assembly 8. The water outlet directions of the second water outlets 252, the water outlet directions of the third water outlets 262, and the water outlet directions of the fourth water outlets 272 are all parallel to the first axis, and thus are all perpendicular to the water outlet direction of the first water outlet 152. Of course, the water outlet directions of the second water outlets 252, the water outlet directions of the third water outlets 262, and the water outlet directions of the fourth water outlets 272 intersecting or being the same as the water outlet direction of the first water outlet 152 can also achieve the purpose of this application. Among them, the fourth water outlets 272 are all located on the periphery of the second water outlets 252, and the second water outlets 252 are all located on the periphery of the third water outlets 262. The second water outlets 252, the third water outlets 262, and the fourth water outlets 272 are all used to realize the function of spraying water. The water distribution base 21 is further provided with a shaft sleeve 213 extending towards the fixed base 13. The shaft sleeve 213 is provided with a shaft hole 28 for inserting the convex shaft 16. The insertion end of the shaft hole 28 is provided with a chamfer 281 for pressing the snap spring 4 to deform the snap spring 4. The hole wall of the shaft hole 28 is provided with a second annular groove 282. The water distribution base 21 is rotatably connected through the cooperation of the shaft hole 28 and the convex shaft 16. Of course, in other embodiments, the shaft hole 28 can also be arranged on the fixed component 1, and the convex shaft 16 can correspondingly also be arranged on the water distribution base 21, which does not affect the connection relationship between the two. The water distribution base 21 is further provided with a convex block 211 extending towards the water outlet base 12. The convex block 211 is configured to be suitable for passing through the opening of the accommodating groove 123 and inserting into the accommodating groove 121. The surface of the convex block 211 facing the first abutting surface 122 forms a second abutting surface 212, and the second abutting surface 212 is opposite to the first abutting surface 122 along the circumferential direction. The water distribution base 21 is further provided with an insertion block 29, and the insertion block 29 is configured to be suitable for passing through the opening of the sliding groove 172 and inserting into the sliding groove 17. The upper surface of the water distribution base 21 facing the top cover 112 is provided with three positioning pits 215 along the circumferential direction. In this embodiment, a plurality of clamping blocks 214 are further arranged on the outer circumferential surface of the water distribution base 21.

[0061] As Figure 7As shown, in this embodiment, the water outlet sleeve 23 is annular and is only used to sleeved outside each fourth water outlet 272.

[0062] As Figure 7 shown, in this example, the water outlet surface cover 22 is provided with an operation handle 221 extending radially and a plurality of card seats 222. Each card seat 222 is provided with a card slot 223, and the card slot 223 is used to cooperate with the card block 214 to rotatably lock the water outlet surface cover 22 to the water distribution base 21 and clamp the water outlet sleeve 23 between the two. Therefore, the assembly among the water distribution base 21, the water outlet sleeve 23 and the water outlet surface cover 22 in the rotating assembly 2 is very convenient.

[0063] As Figure 10 and Figure 12 shown, the first spring 3 is placed in the accommodation groove 121 and is always located between the first abutting surface 122 and the second abutting surface 212. Since the first spring 3 is placed in the accommodation groove 121, even if the convex block 211 disengages from the accommodation groove 121, the state of the first spring 3 is reliable.

[0064] As Figure 8 and Figure 3 shown, the snap ring 4 is annular with an opening and is wavy after being unfolded in the circumferential direction. The snap ring 4 is placed in the first annular groove 161 and extends into the second annular groove 282 to limit and cooperate the rotating assembly 2 and the fixed assembly 1 in the first axial direction. The shape of the snap ring 4 in this embodiment makes the snap ring 4 more evenly stressed in the circumferential direction during deformation and easier to deform.

[0065] As Figure 2 , Figure 3 , Figure 9 and Figure 11 shown, the blocking member 5 is driven by gravity to roll or slide in the sliding groove 17. In this embodiment, the blocking member 5 is a ball, which rolls in the sliding groove 17, and the insertion block 29 is only allowed to insert into the sliding groove 17 when the blocking member 5 is away from the limiting wall 171, while when the blocking member 5 stops at the limiting wall 171, the insertion block 29 cannot insert into the sliding groove 17. In other embodiments, the blocking member 5 can also be a slider that slides in the sliding groove 17.

[0066] As Figure 2 shown, the positioning assembly 6 is placed in the positioning seat 18, and the positioning assembly 6 includes a positioning pin 61 and a second spring 62. One end of the second spring 62 abuts against the top cover 112, and the other end abuts against the positioning pin 61, so that the positioning pin 61 extends out of the opening of the positioning seat.

[0067] As Figure 2As shown, the first sealing assembly 7 is placed in the first sealing cavity. The first sealing assembly 7 includes a first leather cup 71 and a third spring 72. One end of the third spring 72 abuts against the handle 111, and the other end abuts against the first leather cup 71, holding the first leather cup 71 against the outer circumferential surface of the water distribution seat 21 to achieve sealed communication between the water inlet channel 14 and the second water passing port 241, the fourth water passing port 251, the fifth water passing port 261 or the sixth water passing port 271.

[0068] As Figure 2 and Figure 6 shown, the second sealing assembly 8 is placed in the second sealing cavity. The second sealing assembly 8 includes a second leather cup 81 and a fourth spring 82. One end of the fourth spring 82 abuts against the water distribution seat 21, and the other end abuts against the second leather cup 81, holding the second leather cup 81 against the lower surface of the water outlet seat 12 to achieve sealed communication between the water passing channel 24 and the first water passing port 151.

[0069] As Figure 2 and Figure 5 shown, the sealing ring 9 is placed in the sealing ring groove 162 to achieve sealing between the convex shaft 16 and the shaft hole 28.

[0070] In the hand-held shower head 10 of this embodiment, first, the fixing assembly 1 and the rotating assembly 2 are respectively assembled and fixed. Then, the snap ring 4 is placed into the first annular groove 161, the blocking member 5 is placed into the sliding groove 17, the positioning assembly 6 is placed into the positioning seat 18, the first sealing assembly 7 is placed into the first sealing cavity, the second sealing assembly 8 is placed into the second sealing cavity, and the sealing ring 9 is placed into the sealing ring groove 162. Finally, the convex shaft 16 is inserted into the shaft hole 28, and the chamfer 281 at the inserted end of the shaft hole 28 presses against the snap ring 4 to cause elastic deformation of the snap ring 4 and squeeze it into the shaft hole 28 until it falls into the second annular groove 282 and elastically recovers, so that the rotating assembly 2 and the fixing assembly 1 are rotationally connected with axial limit. At this time, the hand-held shower head 10 is assembled. Therefore, in this embodiment, only one plugging operation is required to establish a rotation connection relationship with axial limit between the rotating assembly 2 and the fixing assembly 1, making the assembly of the fixing assembly 1 and the rotating assembly 2 simpler.

[0071] After the hand-held shower head 10 is assembled, as Figure 11 and Figure 12As shown, when the rotating assembly 2 rotates relative to the fixed assembly 1 to the first position, the water passage 24 communicates with the water inlet passage 14 and the first water outlet passage 15 to form jet water. Specifically, the second water through hole 241 is hermetically communicated with the water inlet passage 14 through the first sealing assembly 7, the third water through hole 242 is hermetically communicated with the first water through hole 151 through the second sealing assembly 8, and water flows out from the first water outlet 152. At this time, the plug 29 passes through the chute opening 172 and is inserted into the chute 17, and the convex block 211 passes through the receiving groove opening 123 and is inserted into the receiving groove 121, causing the first spring 3 to be compressed and elastically deformed. The positioning pin 61 abuts against the upper surface of the water distribution seat 21 and is not in the three positioning pits 215, which is beneficial for the first spring 3 to drive the rotating assembly 2 to rotate to the second position. At this time, the extending direction of the operating handle 221 is the same as the axial direction of the handle 111, so that the user can apply force through the operating handle 221 to overcome the elastic force of the first spring 3 and keep the rotating assembly 2 in the first position.

[0072] As Figure 9 and Figure 10 shown, when the rotating assembly 2 is in the first position, the user releases the operating handle 221, and the first spring 3 elastically recovers and drives the rotating assembly 2 to rotate relative to the fixed assembly 1 to the second position. At this time, the second water outlet passage 25 communicates with the water inlet passage 14. Specifically, the fourth water through hole 251 is hermetically communicated with the water inlet passage 14, and water flows out from each second water outlet 252. At this time, the convex block 211 is pushed out of the receiving groove 121 by the first spring 3, the plug 29 does not pass through the chute opening 172 and is inserted into the chute 17, and the positioning pin 61 extends into the positioning pit 215 corresponding to the second position. Since when the user does not apply force, the hand-held shower head 10 will inevitably switch from the jet water state of the first water outlet 152 to the spray water state of the second water outlet 252, so that the hand-held shower head 10 can avoid being in the jet water state every time it starts to be used.

[0073] The user continues to drive the operating handle 221 to rotate the rotating assembly 2 to the third position. At this time, the third water outlet passage 26 communicates with the water inlet passage 14. Specifically, the fifth water through hole 261 is hermetically communicated with the water inlet passage 14 through the first sealing assembly 7, and water flows out from each third water outlet 262. At this time, the convex block 211 is far away from the receiving groove 121, the plug 29 is far away from the chute 17, and the positioning pin 61 extends into the positioning pit 215 corresponding to the third position.

[0074] The user continues to drive the operating handle 221 to rotate the rotating assembly 2 to the fourth position. At this time, the fourth water outlet passage 27 communicates with the water inlet passage 14. Specifically, the sixth water through hole 271 is hermetically communicated with the water inlet passage 14 through the first sealing assembly 7, and water flows out from each fourth water outlet 272. At this time, the convex block 211 is even farther away from the receiving groove 121, the plug 29 is even farther away from the chute 17, and the positioning pin 61 extends into the positioning pit 215 corresponding to the fourth position.

[0075] Since the convex block 211 is not inserted into the receiving groove 121 when the rotating assembly 2 rotates between the second position, the third position and the fourth position, the first spring 3 does not deform.

[0076] The positioning pin 61 extends into one of the three positioning pits 215 when the rotating assembly 2 rotates to the second position, the third position and the fourth position, enabling the user to have a clear sense of gear when switching between three spray water modes.

[0077] As Figure 9 and Figure 11 shown, when the rotating assembly 2 rotates from the second position to the first position, if the water outlet direction of the first water outlet 152 is upward relative to the horizontal plane, the blocking member 5 rolls to abut against the limiting wall 171. At this time, the blocking member 5 does not allow the insertion block 29 to enter the sliding groove 17, so the rotating assembly 2 cannot rotate to the first position and the first water outlet 152 cannot discharge water. Therefore, the handheld shower head 10 of this embodiment has higher safety. Only when the water outlet direction of the first water outlet 152 is parallel or downward relative to the horizontal plane, the blocking member 5 moves away from the limiting wall 171. At this time, the blocking member 5 allows the insertion block 29 to pass through the sliding groove opening 172 and insert into the sliding groove 17, and the rotating assembly 2 can rotate to the first position and the first water outlet 152 discharges water.

[0078] The above description of the specification and embodiments is used to explain the protection scope of the present application, but does not constitute a limitation on the protection scope of the present application.
