Description

A shower head Technical Field

[0001] The present invention relates to the field of bathroom fixtures, in particular to a shower head. Background Art

[0002] After using faucets, bubblers, shower heads and other bathroom products for a period of time, the filters in their water outlet channels will be covered with scale or accumulate granular impurities, affecting the water output. Therefore, the filters need to be cleaned regularly. Traditional filters are typically compressed between the outlet end cap and the outlet body of the water outlet channel, requiring the outlet end cap to be opened for cleaning, which is inconvenient. To address this issue, a Chinese patent document discloses a water outlet structure (publication number CN219280829U), which specifically includes a water spray former and a water outlet end. The water spray former is rotatably disposed at the water outlet end. The water spray former includes a first water flow surface, a second water flow surface, and a water flow passage. The first water flow surface and the second water flow surface are connected by the water flow passage. When the first water flow surface is on the outlet side, the second water flow surface is on the inlet side. When the second water flow surface is on the outlet side, the first water flow surface is on the inlet side. The water outlet structure produces different water sprays when the first water flow surface is on the outlet side and when the second water flow surface is on the outlet side. The above patent document adopts a method of flipping the water flow surface to reduce the difficulty of cleaning and prevent the water outlet channel from being clogged by impurities.

[0003] In the above patent, in order to prevent the water splash former from falling off, a ball socket that matches the water splash former needs to be set in the water outlet, and the water splash former will press against the ball socket and be able to rotate in the ball socket. In order to ensure that the water splash former can be flipped at various angles, the processing accuracy of the relevant parts that make up the ball socket is required to be high. When the processing accuracy of the ball socket is insufficient or there is a deviation in the assembly position, the water splash former may be unable to flip normally during the flipping process due to the misalignment between the rotation center point of the ball socket and the rotation center point of the water splash former itself. Therefore, this type of current bathroom products have high requirements for processing accuracy, which will lead to reduced production and assembly efficiency and reduced product yield. Technical issues

[0004] The technical problem to be solved by the present invention is to provide a shower head which reduces the processing difficulty while ensuring the smoothness of the flipping. Technical Solutions

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A shower head comprises a main body, a water outlet panel and a limiting member;

[0007] The main body is provided with a water outlet channel and a water outlet cavity;

[0008] The water outlet panel is flippably arranged in the water outlet channel;

[0009] The water outlet channel is provided with a clamping ring capable of pressing against the water outlet panel;

[0010] The limiting member has a limiting portion, which is arranged in the water outlet cavity and forms a clearance space for the water outlet panel to flip over;

[0011] When the axis of the water outlet panel coincides with, is parallel to, or forms an angle with the axis of the clamp ring, the water outlet panel can move along the axial direction of the clamp ring toward the limiting portion and press against the limiting portion. Beneficial effects

[0012] The beneficial effects of the present invention are that the rotational pivot point defined by the main body and the rotational pivot point of the water outlet panel do not need to remain coincident during the non-rotation process, and the water outlet panel is restricted in the clearance space by the limiting member arranged in the water outlet cavity; when the limiting member is made of a flexible material, the water outlet panel and the clamping ring are pressed against each other in the axial direction of the clamping ring, and the water outlet panel can be smoothly flipped by squeezing the limiting portion during the flipping process, that is, when the flipping space of the water outlet panel is insufficient, the water outlet panel, when a part of its edge is pressed against the clamping ring, moves the other part of its edge along the axial direction of the clamping ring toward the limiting portion to squeeze the limiting portion and cause the limiting portion to deform, and the deformation of the limiting portion provides flipping space for the water outlet panel; and when the limiting member is made of a rigid material, since the water outlet panel can move toward the limiting portion in the axial direction of the clamping ring, the gap between the limiting member and the water outlet panel is occupied by the movement, thereby providing clearance space for the flipping of the water outlet panel. The positioning portion cooperates with the retaining ring to restrict the water outlet panel from rotating within the clearance space, preventing the water outlet panel from falling out of the water outlet channel and sliding into the water outlet cavity or completely separating from the main body. The present invention provides clearance space for the water outlet panel to flip over, while ensuring good structural stability when the water outlet panel is not flipped over.

[0028] To illustrate the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and accompanying drawings.

[0029] Referring to Figures 1 to 9, a shower head includes a main body 1, a water outlet panel 2, and a stopper 3. The main body 1 includes a water outlet channel 11 and a water outlet cavity 12. The water outlet panel 2 is reversibly disposed within the water outlet channel 11. The water outlet channel 11 includes a clamping ring 4 capable of pressing against the water outlet panel 2. The stopper 3 includes a stopper 31 disposed within the water outlet cavity 12 and forming a clearance space for the water outlet panel 2 to rotate. When the axis of the water outlet panel 2 coincides with, is parallel to, or forms an angle with the axis of the clamping ring 4, the water outlet panel 2 can move along the axial direction of the clamping ring 4 toward the stopper 31 and press against the stopper 31. The main body 1 includes a water outlet body 101 and a grip body 102 that are interconnected, and the water outlet cavity 12 and the water outlet channel 11 are disposed within the water outlet body 101.

[0030] Preferably, the limiting portion 31 is incompletely spherical, and in the axial direction of the clamping ring 4, the height of the limiting portion 31 is lower than the height of the water outlet cavity 12; optionally, the limiting member 3 can be flexible or rigid. Preferably, the limiting portion 31 is flexible, that is, it has an elastic mesh structure. When the axis of the water outlet panel 2 and the axis of the water outlet channel 11 are perpendicular to each other and the circumferential side wall of the water outlet panel 2 is pressed against the clamping ring 4, the limiting member 3 limits the movement distance of the water outlet panel 2 along the axis of the water outlet channel 11 to 0.3~7mm. Specifically, the limiting member 3 can limit the water outlet panel 2 to the clearance space, and when the water outlet panel 2 is flipped, sufficient flipping space can be provided for the water outlet panel 2 by deforming the limiting portion 31.

[0031] It can be understood that when the processing accuracy of the main body 1 decreases and the rotation center point of the water outlet chamber 12 and the rotation center point of the water outlet panel 2 are misaligned during the flipping of the water outlet panel 2, a limiting member 3 is provided in the water outlet chamber 12 to limit the water outlet panel 2 within the clearance space; when the limiting member 3 is made of a flexible material, the water outlet panel 2 and the clamping ring 4 are pressed against each other in the axial direction of the clamping ring 4, and the water outlet panel 2 can be smoothly flipped by squeezing the limiting portion 31 during the flipping process, that is, when the flipping space of the water outlet panel 2 is insufficient, the water outlet panel 2 squeezes the limiting portion 31 and causes the limiting portion 31 to deform, thereby providing flipping space for the water outlet panel 2; and when the limiting member 3 is made of a rigid material, a gap is left between the limiting member 3 and the water outlet panel 2 in the axial direction of the clamping ring 4, thereby providing clearance space for the flipping of the water outlet panel 2. The positioning portion 31 cooperates with the clamping ring 4 to restrict the water outlet panel 2 from rotating within the clearance space, preventing the water outlet panel 2 from falling out of the water outlet channel 11 and sliding into the water outlet cavity 12 or completely separating from the main body 1. The present invention provides clearance space for the water outlet panel 2 to flip over, while ensuring that the water outlet panel 2 has good structural stability when not flipping over.

[0032] In some embodiments, the limiting member 3 further includes a support portion 32. The support portion 32 and the snap ring 4 are sequentially arranged in the water outlet channel 11 along the water outlet direction. The support portion 32 and the snap ring 4 constitute a pivot limiting space for the water outlet panel 2 to rotate, and the water outlet panel 2 can be pressed against the inner wall of the snap ring 4. The setting of the support portion 32 is used to support the limiting portion 31 so that the limiting portion 31 remains stable in the water outlet cavity 12. The support portion 32 is an annular plate structure. It is worth noting that the rotation pivot of the water outlet panel 2 during the flipping process has a range of movement in the axial direction of the water outlet cavity 12. Specifically, refer to the area formed by the three parallel dotted lines in Figure 4. The range of movement is limited by the snap ring 4 and the support portion 32, and the pivot limiting space refers to this range of movement.

[0033] In some embodiments, a notch 312 coaxially arranged with the clamping ring 4 is provided at one end of the limiting portion 31 away from the clamping ring 4, providing space for the water outlet panel 2 to flip, allowing the water outlet panel 2 to rotate smoothly, reducing water inlet resistance, and increasing the water flow area.

[0034] In some embodiments, a seal 5 is interposed between the support portion 32 of the retaining member 3 and the retaining ring 4 in the axial direction of the retaining ring 4, and the seal 5 is capable of pressing against the circumferential sidewall of the outlet panel 2. Optionally, the seal 5 is a Y-ring or an O-ring. When the seal 5 is a Y-ring, its contact area with the outlet panel 2 is small, thereby minimizing friction on the outlet panel 2.

[0035] In some embodiments, when the seal 5 is a Y-shaped ring, in the axial direction of the retaining ring 4, the Y-shaped opening of the seal 5 is arranged toward the side where the limit member 3 is located, and the support portion 32 of the limit member 3 is embedded in the seal 5. Furthermore, the support portion 32 of the limit member 3 is embedded in the Y-shaped opening of the seal 5, thereby improving the relative position stability between the limit member 3 and other parts, and preventing the seal 5 from falling off from the production process to the use process.

[0036] In some embodiments, the clamping ring 4 is integrally formed with the main body 1 or the clamping ring 4 is detachably connected to the main body 1. When the clamping ring 4 is detachably connected to the main body 1, there are three connection methods for the clamping ring 4 and the main body 1. The first option is that the clamping ring 4 can be threadedly connected to the outer wall of the main body 1, which can ensure that the water outlet panel 2 can be stably flipped in the water outlet cavity 12 while allowing the water outlet panel 2 to be separated from the main body 1; the second option is that the clamping ring 4 is embedded in the water outlet channel 11, and the outer diameter of the clamping ring 4 is greater than or equal to the diameter of the water outlet of the water outlet channel 11. In order to enable the water outlet panel 2 and the clamping ring 4 to be separated from the main body 1 and to facilitate assembly, an assembly window 121 is provided at one end of the water inlet cavity away from the water outlet channel 11, and a detachable cover plate 13 is provided on the assembly window 121 to prevent water from flowing out of the assembly window 121 and prevent the internal parts of the water inlet cavity from falling. Preferably, the cover plate 13 is threadedly or snap-fitted to the assembly window 121. A third connection scheme involves snapping the snap ring 4 onto the main body 1. When snapping the snap ring 4 onto the main body 1, a sealing ring 6 is interposed between the snap ring 4 and the inner wall of the water outlet channel 11 to improve both connection stability and sealing. In some embodiments, the minimum inner diameter of the snap ring 4 is smaller than the maximum outer diameter of the water outlet panel 2.

[0037] In some embodiments, a boss 7 is provided on the inner wall of the water outlet end of the clamping ring 4 ; when the axis of the water outlet panel 2 coincides with or is parallel to the axis of the clamping ring 4 , the end face of the water outlet panel 2 can press against the boss 7 in the axial direction of the clamping ring 4 .

[0038] In some embodiments, a clearance opening 41 is provided on the circumferential side wall of the clamping ring 4, and the width of the clearance opening 41 is equal to or greater than the axial thickness of the water outlet panel 2; when the axis of the water outlet panel 2 and the axis of the clamping ring 4 are perpendicular to each other, the clamping ring 4 can be pulled out of or inserted into the main body 1 through the clearance opening 41.

[0039] In some embodiments, there are at least two clearance openings 41, and every two clearance openings 41 are arranged opposite to each other, and the minimum distance between the two oppositely arranged clearance openings 41 is less than or equal to the maximum diameter of the water outlet panel 2, so that the water outlet panel 2 maintains a connection relationship with the main body 1 when not subjected to external force.

[0040] In some embodiments, the water outlet panel 2 has a first water flow surface and a second water flow surface. In one embodiment, the distribution pattern of the water outlet holes of the first water flow surface is exactly the same as that of the second water flow surface, so that impurities placed on the surface of the water flow surface and the water flow holes on the water inlet side are washed and discharged to the outside of the water outlet panel 2 by the reverse water flow when the water flow surface is flipped to the water outlet side, and the water flow discharged outward when any water flow surface is on the water outlet side has consistent water splashes; in another embodiment, the distribution pattern of the water outlet holes of the first water flow surface is different from that of the second water flow surface, so that after the water outlet panel 2 is flipped, not only can the water flow holes be cleaned, but also different water splashes can be formed.

[0041] 1 to 6 , the first embodiment of the present invention is as follows:

[0042] A shower head includes a main body 1, a water outlet panel 2 and a limiting member 3; the main body 1 has a water outlet channel 11 and a water outlet cavity 12; the water outlet panel 2 is reversibly arranged in the water outlet channel 11; the water outlet channel 11 has a clamping ring 4 that can press against the water outlet panel 2; the limiting member 3 has a limiting portion 31, which is arranged in the water outlet cavity 12 and forms a clearance space for the water outlet panel 2 to flip; when the axis of the water outlet panel 2 coincides with, is parallel to, or forms an angle with the axis of the clamping ring 4, the water outlet panel 2 can move along the axial direction of the clamping ring 4 toward the limiting portion 31 and press against the limiting portion 31. Preferably, the limiting portion 31 is in an incomplete spherical shape, and in the axial direction of the clamping ring 4, the height of the limiting portion 31 is lower than the height of the water outlet cavity 12; preferably, the limiting portion 31 is an elastic mesh structure. When the axis of the water outlet panel 2 and the axis of the water outlet channel 11 are perpendicular to each other and the circumferential side wall of the water outlet panel 2 is pressed against the clamping ring 4, the limiting member 3 limits the movement distance of the water outlet panel 2 along the axis of the water outlet channel 11 to 0.3-7 mm, that is, the water outlet panel 2 can move axially along the water outlet channel 11 within the range of this movement distance, and the limiting portion 31 is deformed. The limiting member 3 also has a supporting portion 32. The supporting portion 32 and the clamping ring 4 are sequentially arranged in the water outlet channel 11 along the water outlet direction. The supporting portion 32 and the clamping ring 4 constitute a pivot limiting space for the water outlet panel 2 to rotate, and the water outlet panel 2 can press against the inner wall of the clamping ring 4. The support portion 32 is an annular plate structure; the minimum inner diameter of the clamping ring 4 is smaller than the maximum outer diameter of the water outlet panel 2 .

[0043] In this embodiment, in the axial direction of the clamping ring 4, a sealing member 5 is sandwiched between the supporting portion 32 of the limit member 3 and the clamping ring 4, and the sealing member 5 can be pressed against the circumferential side wall of the water outlet panel 2. Preferably, the sealing member 5 is a Y-shaped ring. In the axial direction of the clamping ring 4, the Y-shaped opening of the sealing member 5 is arranged toward the side where the limit member 3 is located, and the supporting portion 32 of the limit member 3 is embedded in the sealing member 5. Further, the supporting portion 32 of the limit member 3 is embedded in the Y-shaped opening of the sealing member 5.

[0044] In this embodiment, the limiting portion 31 and the supporting portion 32 are integrally formed, and the clamping ring 4 is clamped to the main body 1 . When the clamping ring 4 is clamped to the main body 1 , a sealing ring 6 is sandwiched between the clamping ring 4 and the inner wall of the water outlet channel 11 .

[0045] The working principle of this embodiment is:

[0046] The water outlet panel 2 can squeeze the limiting portion 31 in the clearance cavity 311 , so that the limiting portion 31 is deformed and the water outlet panel 2 can continue to flip to any angle.

[0047] 5 to 8 , the second embodiment of the present invention is as follows:

[0048] The difference between this embodiment and the first embodiment is that the structure of the snap ring 4 is different.

[0049] In this embodiment, a clearance opening 41 is provided on the circumferential side wall of the clamping ring 4, and the width of the clearance opening 41 is greater than the axial thickness of the water outlet panel 2. The width of the clearance opening 41 refers to the length of the clearance opening 41 in the circumferential direction of the clamping ring 4; when the axis of the water outlet panel 2 and the axis of the clamping ring 4 are perpendicular to each other, the clamping ring 4 can be pulled out of or inserted into the main body 1 through the clearance opening 41; there are at least two clearance openings 41, and every two clearance openings 41 are arranged opposite to each other, and the minimum spacing between the two oppositely arranged clearance openings 41 is equal to the maximum diameter of the water outlet panel 2.

[0050] The working principle of this embodiment is:

[0051] When the axis of the water outlet panel 2 is perpendicular to the axis of the clamping ring 4 , the water outlet panel 2 is pulled out or inserted into the clearance opening 41 , and the water outlet panel 2 is not radially opposite to the clearance opening 41 , it will be restricted in the water outlet cavity 12 .

[0052] The third embodiment of the present invention is:

[0053] The difference between this embodiment and the first or second embodiment is that the clamping ring 4 and the main body 1 are formed integrally.

[0054] The fourth embodiment of the present invention is:

[0055] The difference between this embodiment and the first embodiment is that the snap ring 4 is embedded in the water outlet channel 11, and the outer diameter of the snap ring 4 is larger than the diameter of the water outlet of the water outlet channel 11; an assembly window 121 is opened at the end of the water inlet cavity away from the water outlet channel 11, and a removable cover plate 13 is provided on the assembly window 121.

[0056] The fifth embodiment of the present invention is:

[0057] The difference between this embodiment and the first embodiment is that the clamping ring 4 is threadedly connected to the outer wall of the main body 1 .

[0058] Please refer to FIG9 , the sixth embodiment of the present invention is:

[0059] The difference between this embodiment and embodiments one to five is that a boss 7 is provided on the inner wall of the water outlet end of the clamping ring 4; when the axis of the water outlet panel 2 coincides with or is parallel to the axis of the clamping ring 4, the end face of the water outlet panel 2 can be pressed against the boss 7 in the axial direction of the clamping ring 4, thereby supporting the water outlet panel 2. A plurality of bosses 7 can be provided, and all bosses 7 are arranged at equal intervals, or the boss 7 is annular.

[0060] In summary, the shower head provided by the present invention uses a deformable limiter to prevent the water outlet panel from falling into the water outlet cavity when it is subjected to external force during the flipping process or when it is subjected to external force and gravity in a non-water-flowing state, causing the water outlet panel to be unable to be in the working position. Due to the provision of the limiter, the water outlet panel can exert pressure on the limiting part of the limiter during the flipping process, causing the limiting part to deform, thereby making the rotation center point of the water outlet panel basically coincide with the rotation center point defined by the water outlet body through the offset of the water outlet panel, so that the water outlet panel can flip smoothly even when the production precision is deliberately reduced to improve the production efficiency and assembly efficiency, and in some schemes, the friction resistance generated during the flipping process can also be reduced, thereby improving the user experience.

[0061] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention.
