Specific Embodiments

[0032] The following will further describe in detail the specific embodiments of the present utility model with reference to the accompanying drawings and embodiments. The following embodiments are used to illustrate the present utility model but are not used to limit the scope of the present utility model.

It should be understood that when we say that a component is "connected" to another component, it can be directly connected to other components, or there may also be intermediate components. The term "and / or" used herein includes any and all units and all combinations of one or more of the associated listed items.

[0034] As Figures 1 to 10 shown, the present utility model relates to a shower control box, comprising: a box body 1, a valve body assembly 2, a button assembly 3 and a limiting member 4. The box body 1 is provided with an installation hole 11, and an accommodation groove 13 is circumferentially provided on the inner side of the installation hole 11. The valve body assembly 2 is arranged in the box body 1. The valve body assembly 2 is provided with a valve core 21. The button assembly 3 is inserted through the installation hole 11 and can axially move relative to the box body 1 along the installation hole 11. The button assembly 3 is connected to the valve core 21. A limiting groove 311 is axially provided on the outer side of the button assembly 3 along the installation hole 11. The limiting member 4 includes a snap ring 42 and a limiting protrusion 41. The snap ring 42 is embedded in the accommodation groove 13 and is arranged around the button assembly 3. The limiting protrusion 41 is arranged on the snap ring 42, and the limiting protrusion 41 penetrates into the limiting groove 311.

[0035] In the present utility model, the button assembly 3 is inserted through the installation hole 11 of the box body 1 and can axially move relative to the box body 1 along the installation hole 11. The button assembly 3 is connected to the valve core 21, so that the button assembly 3 can control the opening and closing of the valve core 21. Then, by installing the snap ring 42 in the accommodation groove 13 on the inner side of the installation hole 11, the stability of the position of the snap ring 42 can be ensured. The snap ring 42 is arranged around the button assembly 3, and the limiting protrusion 41 on the snap ring 42 can enter the limiting groove 311 of the button assembly 3, so as to guide the button assembly 3 to stably move axially along the installation hole 11, and can limit the circumferential rotation of the button assembly 3 along the installation hole 11 and limit the radial movement of the button assembly 3 along the installation hole 11, so as to limit the shaking of the button assembly 3 relative to the box body 1 and not affect the user's use, and the experience is better.

[0036] In this embodiment, a notch 44 is provided on the snap ring 42 to connect the inside and outside of the snap ring 42, that is, the snap ring 42 is in a ring shape so that the snap ring 42 has elastic deformation ability, so that the outer diameter of the snap ring 42 can be reduced by squeezing the snap ring 42, and then the snap ring 42 can be easily inserted into the receiving groove 13. After the snap ring 42 is loosened, the snap ring 42 can elastically recover and press against the bottom wall of the receiving groove 13 to improve the stability of the position of the snap ring 42.

[0037] Preferably, the inner side of the retaining ring 42 is evenly distributed with a plurality of ridges 45 along the circumferential direction, and the ridges 45 are extended axially along the mounting hole 11, and the side of the ridges 45 away from the retaining ring 42 is an arc-shaped surface, thereby reducing the friction force on the button assembly 3 and making the pressing of the button assembly 3 smoother.

[0038] Furthermore, the inner side of the retaining ring 42 is flush with the inner side of the mounting hole 11 , thereby preventing an excessive gap from existing between the outer side of the button assembly 3 and the inner wall of the mounting hole 11 , thereby facilitating ensuring the stability of the connection of the button assembly 3 in the mounting hole 11 .

[0039] In this embodiment, a connecting seat 12 is further provided on the inner side of the box body 1 and in an area corresponding to the mounting hole 11. The connecting seat 12 is integrally formed with the box body 1. A connecting hole 121 corresponding to the mounting hole 11 is provided on the connecting seat 12. A bayonet 122 connected to the connecting hole 121 is provided on the connecting seat 12. The retaining ring 42 extends outward to form a clamping block 43, and the clamping block 43 enters into the bayonet 122.

[0040] By setting the connecting seat 12, and opening a connecting hole 121 in the area of ​​the connecting seat 12 corresponding to the mounting hole 11, the button assembly 3 is inserted into the mounting hole 11 and the connecting hole 121, which is beneficial to increase the stability of the position of the button assembly 3, and the block 43 of the retaining ring 42 enters the retaining hole 122 of the connecting seat 12, thereby limiting the circumferential rotation of the retaining ring 42 along the mounting hole 11, and enhancing the stability of the position of the retaining ring 42, so as to ensure that the retaining ring 42 can more stably limit the button assembly 3.

[0041] It should be noted that, in other embodiments, the snap ring 42 can be clamped in the receiving groove 13 only by its own elastic force to limit the circumferential rotation of the snap ring 42 along the mounting hole 11. The snap ring 42 can also be fixed to the receiving groove 13 by glue to also limit the circumferential rotation of the snap ring 42 along the mounting hole 11, ultimately ensuring that the button assembly 3 is more stable and less prone to shaking.

[0042] Specifically, two of the limiting bumps 41 are circumferentially and uniformly distributed on the snap ring 42, and two of the limiting grooves 311 are circumferentially and uniformly distributed on the button body 31. The two limiting bumps 41 correspondingly enter the two limiting grooves 311, so as to strengthen the limiting effect on the button assembly 3 and ensure the stability of the axial movement of the button assembly 3.

[0043] Two of the clamping blocks 43 are circumferentially and uniformly distributed on the snap ring 42, and two of the clamping openings 122 are circumferentially and uniformly distributed on the connecting seat 12. The two clamping blocks 43 correspondingly enter the two clamping openings 122 to further strengthen the stability of the position of the snap ring 42.

[0044] In this embodiment, a mounting member 22 is connected to the valve core 21. A through hole 321 is formed in the button assembly 3. One end of the mounting member 22 away from the valve core 21 is a connecting end 222. The connecting end 222 axially passes through the through hole 321 along the axis of the mounting hole 11 and is connected to the button assembly 3, so that the button assembly 3 can drive the valve core 21 to axially move along the mounting hole 11. A first gap exists between the mounting member 22 and the through hole 321 in the radial direction, and a second gap exists between the button assembly 3 and the connecting end 222 and / or the valve core 21 of the mounting member 22 in the axial direction of the mounting hole 11.

[0045] When the valve body assembly 2 is stably installed but the installation position is inaccurate or the installation is unstable and shakes, causing the position of the valve body assembly 2 in the box body 1 to shift radially along the mounting hole 11, the valve core 21 also shifts radially along the mounting hole 11. Therefore, when there is a first gap between the mounting member 22 and the through hole 321 radially, it can allow the mounting member 22 to displace radially along the mounting hole 11, making it difficult for the mounting member 22 to abut against the inner wall of the through hole 321, thereby ensuring that the button body 31 is not easily stuck. Then, there is a second gap between the button assembly 3 axially along the mounting hole 11 and the end of the mounting member 22 away from the valve core 21 and / or the valve core 21. That is, it allows the mounting member 22 to have a certain displacement amount axially along the mounting hole 11 relative to the button assembly 3. Therefore, the valve body assembly 2 can have a certain displacement amount axially along the mounting hole 11 relative to the button assembly 3. Thus, when the valve body assembly 2 is stably installed but the installation position is inaccurate and tilts relative to the position in the box body 1, it will not affect the smooth assembly of the button assembly 3 and the mounting member 22, nor will it cause the button assembly 3 to be stuck. When the valve body assembly 2 is unstable and shakes axially, it is not easy to drive the button assembly 3 to shake axially. Therefore, the valve body assembly 2 of the present utility model can have a certain displacement amount both axially and radially along the mounting hole 11 relative to the button assembly 3, allowing the valve body assembly 2 to have a certain offset relative to the button assembly 3 in space. By utilizing the above-mentioned axial and radial gaps, it can meet the position adjustment requirements caused by the offset of the valve body assembly 2 after installation. Thus, when the position of the valve body assembly 2 installed in the box body 1 is offset, the valve body assembly 2 will not drive the button assembly 3 to shake, nor will it cause some positions of the button assembly 3 to abut tightly against the inner wall of the mounting hole 11, and further will not cause the button assembly 3 to be stuck when pressed, ensuring that the button assembly 3 is smoother when pressed.

[0046] The button assembly 3 includes a button body 31 and a connecting portion 32 connected together. An activity space 33 is formed between the button body 31 and the connecting portion 32. The through hole 321 is located on the connecting portion 32 and communicates with the activity space 33. The mounting member 22 is a columnar structure. The connecting end 222 of the mounting member 22 is located in the activity space 33, and the outer diameter of the connecting end 222 of the mounting member 22 is greater than the inner diameter of the through hole 321. There is the second gap between the connecting portion 32 axially along the mounting hole 11 and the connecting end 222 of the mounting member 22 and / or the valve core 21.

[0047] Since the outer diameter of the connecting end 222 of the mounting member 22 is greater than the inner diameter of the through hole 321, the connecting end 222 of the mounting member 22 can be restricted from passing through the through hole 321 to disengage from the connecting portion 32, so that the button assembly 3 can drive the valve core 21 to move axially along the mounting hole 11. And because there is a second gap between the connecting portion 32 and the connecting end 222 of the mounting member 22 and / or the valve core 21 in the axial direction of the mounting hole 11, the mounting member 22 can have a certain displacement amount axially relative to the button assembly 3. That is to say, there is a certain offset between the valve body assembly 2 and the mounting member 22 in the axial direction of the mounting hole 11, which is beneficial to the installation of the valve body assembly 2.

[0048] In other embodiments, the button assembly 3 can also be an integral structure. The mounting member 22 passes through the button assembly 3 and is connected to the valve core 21. The connecting end 222 of the mounting member 22 is located at the end of the button assembly 3 away from the valve core 21 and has a second gap with the button assembly 3 in the axial direction of the mounting hole 11, so that there can also be an offset between the mounting member 22 and the valve body assembly 2 in the axial direction.

[0049] In this embodiment, the mounting member 22 is a connecting bolt. A positioning step 221 is provided on the outer periphery of the connecting bolt. The connecting bolt passes through the through hole 321 and is threadedly connected to the valve core 21, and the positioning step 221 abuts against the valve core 21. The connecting end 222 of the mounting member 22 is the screw head end of the connecting bolt. The outer diameter of the screw head end of the connecting bolt is greater than the inner diameter of the through hole 321, and the outer diameter of the positioning step 221 is less than the inner diameter of the through hole 321. There is a second gap between the connecting portion 32 and the screw head end of the connecting bolt and / or the valve core 21.

[0050] That is to say, when the connecting portion 32 is connected to the valve core 21 through the connecting bolt, the threaded section of the connecting bolt is threadedly connected to the valve core 21, and the positioning step 221 of the connecting bolt abuts against the end of the valve core 21. At this time, there is a second gap between the connecting portion 32 and the screw head end of the connecting bolt and / or the valve core 21, so that the connecting bolt can have a certain displacement amount axially relative to the connecting portion 32. At the same time, the outer diameter of the positioning step 221 is less than the inner diameter of the through hole 321, so that the connecting bolt can have a certain displacement amount radially relative to the connecting portion 32. Therefore, finally, the valve body assembly 2 has a certain displacement amount axially and / or radially relative to the button assembly 3. Thus, when the valve body assembly 2 is offset when installed in the box body 1, it is not easy to cause the button assembly 3 to shake or get stuck when pressed.

[0051] In this embodiment, the connecting portion 32 includes a gasket 322 and a sealing ring 323. The through hole 321 is located on the gasket 322. The sealing ring 323 is sleeved outside the gasket 322. The button body 31 is in a cylindrical shape. The gasket 322 is arranged inside the button body 31, and the sealing ring 323 is in interference fit with the inner wall of the button body 31. An activity space 33 is formed between the gasket 322 and the side of the interior of the button body 31 far from the opening.

[0052] By sleeving a sealing ring 323 outside the gasket 322 and then inserting the gasket 322 into the button body 31 to make the sealing ring 323 in interference fit with the inner wall of the button body 31, the button body 31, the gasket 322 and the sealing ring 323 are fixed together, so that the connecting portion 32 can be firmly positioned inside the button body 31.

[0053] Preferably, an annular groove 324 is formed on the outer periphery of the gasket 322, and a part of the sealing ring 323 is embedded in the annular groove 324, so that the sealing ring 323 can be firmly sleeved on the outer periphery of the gasket 322.

[0054] Further, a stop projection 325 is arranged on the side of the gasket 322 close to the button body 31 and abuts against the side of the interior of the button body 31 far from the opening. Thus, when the gasket 322 is inserted into the button body 31 and the stop projection 325 abuts against the side of the interior of the button body 31 far from the opening, the activity space 33 can be formed between the button body 31 and the gasket 322.

[0055] Specifically, the stop projection 325 is arranged on the side of the gasket 322 close to the button body 31 and in the area close to the outer edge, and the stop projection 325 extends along the circumferential direction to form an annular structure. The through hole 321 is located in the middle area of the annular structure. Thus, the stop projection 325 can stably abut against the side of the interior of the button body 31 far from the opening, and the position of the gasket 322 inside the button body 31 can be more stable.

[0056] In this embodiment, the through hole 321 is located in the middle of the gasket 322. The dimension of the middle of the gasket 322 in the axial direction of the mounting hole 11 is smaller than the dimension of the positioning step 221 of the connecting bolt in the axial direction of the mounting hole 11, so that a second gap is formed between the gasket 322 and the screw head end of the connecting bolt and / or the valve element 21. After the positioning step 221 of the connecting bolt abuts against the end of the valve element 21, the connecting bolt can have a certain displacement in the axial direction relative to the gasket 322.

[0057] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and substitutions can be made, and these improvements and substitutions should also be regarded as the protection scope of the present utility model.
