Description

Technical Field

[0001] This utility model relates to the field of connection device technology, and in particular to a connection device and a shower controller. Background Technology

[0002] Pre-installed shower controllers embed the valve assembly within the wall, with only the knobs or buttons located outside the wall, resulting in a more aesthetically pleasing design compared to other common shower controllers. However, during installation, the valve body must be pre-embedded in the wall. Due to installation errors, the valve body cannot be guaranteed to be perfectly level after pre-embedding, resulting in an angle between the valve body and the wall. This causes the button valve assembly and thermostatic valve assembly installed within the valve body to also tilt, preventing the buttons of the button valve assembly and the knobs of the thermostatic valve assembly from fitting snugly against the wall. This disrupts the overall aesthetics of the shower controller and the wall, thus affecting the user experience. Utility Model Content

Detailed Implementation

[0038] Example 1

[0039] The following is combined Figures 1-5 This embodiment will be described in detail.

[0040] Figure 1 The diagram illustrates a pre-embedded shower controller in the prior art. Due to installation errors, the valve body 10' failed to maintain a horizontal position during the pre-embedding process, resulting in an angle α between the installed valve body 10' and the horizontal line. Consequently, the valve assembly 20', installed on the valve body 10', also exhibits a corresponding tilt angle. Furthermore, the knobs or buttons connected to the valve assembly cannot fit snugly against the wall, disrupting the overall aesthetics of the shower controller and the wall, thus impacting the user experience.

[0041] To overcome the shortcomings of existing technologies, this embodiment proposes a connecting device designed to compensate for the tilt angle caused by installation errors during the pre-embedding of the valve body 30. Specifically, as shown... Figure 2 and Figure 3 As shown, the connecting device includes a first adjusting mechanism 10, which includes a connecting sleeve 101 and a first connecting rod 103 passing through the first end of the connecting sleeve 101. The second end of the connecting sleeve 101 is used to connect to the control end of the first valve group 501. The first end of the first connecting rod 103 rotates along its axis and is connected to the connecting sleeve 101. By rotating the first connecting rod 103, the connecting sleeve 101 is driven to rotate, thereby controlling the first valve group 501. At the same time, the first end of the first connecting rod 103 is oscillatingly connected to the connecting sleeve 101. Thus, by oscillating the first connecting rod 103, its installation angle is changed to compensate for the installation error of the valve body 30, so that the knob 60 connected to the second end of the first connecting rod 103 can fit against the wall, increasing the tolerance range of the valve body 30 during the pre-embedding process, improving the installation efficiency, and expanding its application range.

[0042] like Figure 4 and Figure 5As shown, the connecting device also includes a second adjusting mechanism 20. The second adjusting mechanism 20 includes a base 201 and a second connecting rod 202. The base 201 and the second connecting rod 202 are provided with interconnected channels. The first end of the second connecting rod 202 is movably sealed and oscillatingly connected to the base 201, and the second end of the second connecting rod 202 is connected to the outlet end of the second valve assembly 502, which is connected to the channel. The second valve assembly 502 is oscillating relative to the base 201 based on the second connecting rod 202, allowing the second valve assembly 502 to oscillate relative to the base 201. This oscillation of the second valve assembly 502 changes its installation angle to compensate for the installation error of the valve body 30.

[0043] It can be seen that the first adjustment mechanism 10 and the second adjustment mechanism 20 are adapted to different types of valve groups, so that when different types of valve groups have errors during the pre-embedding process of the valve body 30, the installation angle error of the valve body 30 can be offset by the first adjustment mechanism 10 and the second adjustment mechanism 20 respectively.

[0044] like Figure 2 and Figure 3 As shown, the first adjusting mechanism 10 also includes wear-resistant rings 104, which are spherically fitted to both sides of the first swing portion 1031 to prevent the first swing portion 1031 from directly abutting against the connecting sleeve 101. The first swing portion 1031 rotates along its axis and is driven to the connecting sleeve 101, and the first swing portion 1031 is oscillatingly connected to the connecting sleeve 101. Specifically, the first swing portion 1031 is spline-fitted to the connecting sleeve 101 to drive the connecting sleeve 101 to rotate. In addition to the spline-fitted connection, a structure can also be provided between the first swing portion 1031 and the connecting sleeve 101, such as a convex and concave part that are mutually engaged, to drive the connecting sleeve 101 to rotate by rotating the first connecting rod 103. The first end of the connecting sleeve 101 is provided with a first opening 1011 for the first connecting rod 103 to pass through. The radial dimension of the first opening 1011 is smaller than the radial dimension of the first swing part 1031 to prevent the first connecting rod 103 from coming out of the connecting sleeve 101. There is a first movable gap 102 between the first opening 1011 and the first connecting rod 103. The first movable gap 102 constitutes the swing space of the first connecting rod 103, that is, the first opening 1011 restricts the swing range of the first connecting rod 103. Furthermore, the side wall of the connecting sleeve 101 is provided with a locking hole 1012 for connecting fasteners so that the connecting sleeve 101 is locked to the first valve assembly 501.

[0045] like Figure 4 and Figure 5As shown, the second adjusting mechanism 20 further includes a bushing 203 and a pressure cap 204. The first end of the second connecting rod 202 is provided with a second swing portion 2021. The second swing portion 2021 is movably sealed and sway-connected to the seat 201. The pressure cap 204 is connected to the seat 201 to spherically connect the bushing 203 to the second swing portion 2021. The seat 201 also has a first sealing ring 2061 for movably sealing the connection to the second swing portion 2021, and a second sealing ring 2062 for movably sealing the connection to the valve body 30. The pressure cap 204 has a second opening 2031, and a second movable gap 205 exists between the second opening 2031 and the second connecting rod 202. The second movable gap 205 constitutes the swing space of the second connecting rod 202, meaning the second opening 2031 restricts the swing range of the second connecting rod 202.

[0046] In this embodiment, the outer surfaces of the first swing portion 1031 and the second swing portion 2021 are all spherical. In other embodiments, only a portion of the first swing portion 1031 and the second swing portion 2021 may be spherical, that is, the position where the first swing portion 1031 mates with the wear-resistant ring 104 may be spherical, and the positions where the second swing portion 2021 mates with the bushing 203 and the first sealing ring 2061 may be spherical.

[0047] Example 2

[0048] The following is combined Figures 6-13 This embodiment will be described in detail.

[0049] This embodiment proposes a shower controller, including a valve body 30 and a panel assembly 40 connected to the valve body 30. The space enclosed by the panel assembly 40 and the valve body 30 constitutes an installation space. A first valve group 501 and a second valve group 502 are provided in the installation space. The water outlet of the first valve group 501 is connected to the water inlet of the second valve group 502. It also includes the connecting device as described above. A first adjusting mechanism 10 is connected to the control end of the first valve group 501, and a second adjusting mechanism 20 is connected to the water outlet of the second valve group 502. The valve body 30 is provided with a plurality of water inlet ports 301 and water outlet ports 302. The water inlet port of the first valve group 501 is connected to the water inlet port 301, and the water outlet port of the second valve group 502 is connected to the water outlet port 302 through a channel in the second adjusting mechanism 20.

[0050] like Figure 12 and Figure 13As shown, the first valve group 501 is fixedly connected to the valve body 30, and the second valve group 502 is connected to the side of the panel assembly 40 facing the installation space. The end of the first connecting rod 103 away from the first valve group 501 is connected to a knob 60 that is axially movable along the first connecting rod 103. The knob 60 can drive the first connecting rod 103 to rotate. The seat 201 is axially movable and connected to the valve body 30. It also includes a flexible tube 70, the two ends of which are respectively connected to the water outlet of the first valve group 501 and the water inlet of the second valve group 502. The deformation of the flexible tube 70 and the adjustable distance of the knob 60 and the seat 201 are adapted to the adjustable distance of the panel assembly 40.

[0051] To accommodate valve bodies 30 with different pre-embedded depths, the panel assembly 40 has an adjustable distance X relative to the valve body 30. The flexible tube 70 deforms to accommodate the adjustment of the panel assembly 40, such as... Figure 12 As shown. Figure 13 This illustrates the adjustable distances of the panel assembly 40, knob 60, and seat 201 when the valve body 30 has different pre-embedded depths. During panel adjustment, knob 60 and seat 201 are displaced to adapt to the adjustable distance X of the panel assembly 40, such as... Figure 13 As shown. Furthermore, the adjustable distance Y of the knob 60 and the adjustable distance Z of the base 201 are not less than the adjustable distance X of the panel assembly 40, ensuring that the knob 60 will not disengage from the first adjustment mechanism 10 and the base 201 will not disengage from the second adjustment mechanism 20 during the adjustment of the panel assembly 40, thereby preventing controller failure.

[0052] In practical applications, the first valve group 501 is a temperature-regulating valve group. The inlet port 301 includes a hot water port and a cold water port. The hot water port is used to introduce hot water and connects to the hot water chamber of the temperature-regulating valve group, and the cold water port is used to introduce cold water and connects to the cold water chamber of the temperature-regulating valve group. The second valve group 502 is a push-button valve group. The push-button valve group has multiple buttons. Pressing any button opens the corresponding outlet port 302.

[0053] The installation process of the shower controller proposed in this embodiment is as follows:

[0054] S1. The valve body 30 is pre-embedded in the wall. If an installation error occurs during the pre-embedding process, causing the valve body 30 to be in a non-horizontal state, such as... Figure 10 and Figure 11 As shown.

[0055] S2. Connect the first regulating mechanism 10 to the control end of the first valve group 501, and install the first valve group 501 with the first regulating mechanism 10 installed inside the valve body 30; connect the second regulating mechanism 20 to the outlet end of the second valve group 502, and connect the second valve group 502 to the panel assembly 40.

[0056] S3. Connect the panel assembly 40 to the valve body 30, so that the seat 201 is slidably connected to the water outlet 302. At the same time, the first adjustment mechanism 10 passes through the panel assembly 40, and the knob 60 is connected to one end of the first valve group 501 away from the first connecting rod 103.

[0057] S4. The knob 60 is oscillatingly connected to the first connecting rod 103 and the connecting sleeve 101, thereby adjusting the installation angle of the knob 60 to compensate for the installation error of the valve body 30, so that the knob 60 fits snugly against the panel assembly 40. Figure 10 As shown; simultaneously, the second valve assembly 502 is oscillatingly connected to the seat 201 via the second connecting rod 202, thereby adjusting the installation angle of the second valve assembly 502 to compensate for the installation error of the valve body 30, making the second valve assembly 502 fit the panel assembly 40, as shown. Figure 11 As shown.

[0058] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the scope of protection of this utility model.
