Technical Field
[0001] This utility model relates to the field of bathroom product technology, specifically to a water inlet connector and a water outlet device. Background Technology
[0002] During the installation of a water outlet device, it is usually necessary to connect it to a water outlet connector pre-embedded in the wall to introduce water flow into the device. Currently, most water outlet devices sold on the market, such as shower faucets, are equipped with an inlet connector for connecting to the water outlet connector in the wall.
[0003] However, the applicant discovered at least the following problems during the actual installation process:
[0004] When the water outlet connector embedded inside the wall is misaligned, the water inlet connector of the water outlet device will also be misaligned after connection. This makes it impossible for the water inlet connector to maintain a perpendicular connection with the wall, making the installation of the water outlet device with the water inlet connector more difficult. Moreover, forcing the connection can easily damage the threads of the connector, which may lead to leaks later on and cause instability in the entire connection structure, affecting its normal use. Utility Model Content
[0005] This utility model provides a water inlet connector and a water outlet device to solve or improve the problem that in related technologies, the water inlet connector of the water outlet device cannot be connected to the wall surface after being connected to the water outlet connector pre-embedded in the wall, which makes the installation of the water outlet device equipped with the water inlet connector difficult, and the threads of the connector are easily damaged during the forced connection process, resulting in water leakage and instability of the entire connection structure.
[0006] Firstly, this utility model provides a water inlet connector, comprising:
[0007] The first connector is suitable for connection with the water outlet connector pre-embedded in the wall;
[0008] The second connector is connected to the water outlet of the first connector. One of the first connector and the second connector is provided with a spherical part and the other is provided with a spherical groove. The spherical part is rotatably engaged in the spherical groove.
[0009] A connector is fitted onto the water inlet end of the second connector, and the first connector is inserted into the connector. The connector is provided with an abutment surface, which is adapted to fit against the wall.
[0010] In one alternative implementation, it further includes:
[0011] A first seal is disposed between the spherical portion and the spherical groove.
[0012] In one alternative embodiment, one of the spherical portion and the spherical groove is provided with an annular groove adapted to the first seal, and the first seal is embedded in the annular groove.
[0013] In one alternative embodiment, the connector includes:
[0014] The connecting part has a cylindrical structure, the water inlet end of the second connector is provided with a first external thread, the inner wall of the connecting part is provided with an internal thread that matches the first external thread, and the first connector is inserted into the connecting part;
[0015] An abutment portion is provided on the side of the connecting portion facing the wall. The number of abutment portions is at least two, and each abutment portion is provided along the circumference of the connecting portion. Each abutment portion is provided with an abutment surface.
[0016] In one alternative implementation, it further includes:
[0017] The limiting member has a first limiting groove on the inner wall of the connecting part and a second limiting groove on the outer wall of the first connector, which is opposite to the first limiting groove. One end of the limiting member is inserted into the first limiting groove and the other end is inserted into the second limiting groove to prevent relative rotation between the connecting part and the first connector.
[0018] In one alternative embodiment, the outer wall of the connecting portion is provided with a polygonal structure.
[0019] In one alternative implementation, it further includes:
[0020] A check valve is inserted into the first connector. The check valve is located at the water inlet end of the first connector and is unidirectionally open from the water inlet end to the water outlet end of the first connector.
[0021] In one alternative implementation, it further includes:
[0022] A filter screen is inserted into the first connector, and the filter screen is located at the water inlet end of the check valve.
[0023] In one alternative implementation, it further includes:
[0024] The second sealing element is disposed between the check valve and the first connector.
[0025] Secondly, this utility model also provides a water outlet device, including a water inlet connector as described in any of the above claims.
[0026] The water inlet connector provided by this utility model allows for relative rotation between the first connector and the second connector through the cooperation of the spherical part and the spherical groove. This way, even if the water outlet connector pre-embedded in the wall is misaligned during the installation of the water inlet connector, the installation angle can be adaptively adjusted by rotation, eliminating problems caused by hole tilt deviation, reducing the hidden dangers such as water leakage and structural instability. Moreover, during the installation process, the abutting surface can be pressed against the wall to quickly ensure that the water outlet direction is perpendicular to the wall, eliminating the need for multiple manual adjustments and leveling. This makes the operation convenient, reduces the installation difficulty, improves assembly efficiency, and ensures normal product use. Attached Figure Description

[0042] The following is combined Figures 1 to 8 This describes the water inlet connector and water outlet device according to embodiments of the present utility model.
[0043] According to an embodiment of this utility model, in one aspect, a water inlet connector is provided, suitable for installation on a water outlet device, to connect a water outlet connector (not shown in the figure) pre-embedded in the wall to the water outlet device. For example... Figure 1 As shown, the water inlet connector includes a first connector 1, a second connector 2, and a connector 3. Specifically, as... Figure 2 As shown, the first connector 1 is adapted to connect to a water outlet connector pre-embedded in the wall. Optionally, as follows: Figure 5 As shown, the water inlet end 5 of the first connector 1 is provided with a second external thread 103 so as to be connected to the water outlet connector in the wall by means of the thread.
[0044] like Figure 3 As shown, the second connector 2 is connected to the outlet end 4 of the first connector 1, and one of the first connector 1 and the second connector 2 is provided with a spherical part 6, and the other is provided with a spherical groove 7. The spherical part 6 is rotatably engaged in the spherical groove 7. That is, at the connection between the second connector 2 and the first connector 1, the first connector 1 is provided with a spherical part 6, and the second connector 2 is provided with a matching spherical groove 7; or, the second connector 2 is provided with a spherical part 6, and the first connector 1 is provided with a matching spherical groove 7. For example, as... Figure 5 As shown, the first connector 1 is provided with a spherical part 6, such as Figure 7As shown, the second connector 2 is provided with a spherical groove 7, and the spherical part 6 is rotatably engaged in the spherical groove 7, thereby having a universal adjustment function, so that the second connector 2 and the first connector 1 can be adaptively adjusted according to the axial direction of the water outlet connector in the wall to meet the actual installation requirements.
[0045] Generally, such as Figure 3 As shown, under normal conditions, the axis of the water outlet connector embedded in the wall is perpendicular to the wall surface 9. Therefore, after connecting to the water inlet connector, the axes of both the second connector 2 and the first connector 1 remain perpendicular to the wall surface 9, thus introducing water into the water outlet device. And as... Figure 4 As shown, when the axial direction of the water outlet connector embedded in the wall cannot be perpendicular to the wall 9 and becomes skewed due to wall verticality deviation, operation deviation, etc., after connecting with the water inlet connector, due to the spherical connection structure, the first connector 1 and the second connector 2 will rotate relative to each other and adaptively adjust the angle deviation. At this time, there is an included angle α between the axial directions of the first connector 1 and the second connector 2.
[0046] Furthermore, such as Figure 3 As shown, connector 3 is sleeved onto the water inlet end 5 of the second connector 2, and the first connector 1 is inserted into connector 3. Figure 2 As shown, the connector 3 is provided with an abutment surface 8, which is adapted to fit against the wall surface 9. In this way, when the first connector 1 is screwed into the water outlet connector in the wall, the abutment surface 8 on the connector 3 will abut against the wall surface 9, thereby driving the second connector 2 to rotate and automatically adjust its axis to be perpendicular to the wall surface 9, thus making it more convenient to adapt to actual installation conditions and realize the smooth and fast installation of the product.
[0047] This design, through the interaction of the spherical part 6 and the spherical groove 7, allows relative rotation between the first connector 1 and the second connector 2. Thus, even if the water outlet connector pre-embedded in the wall is misaligned during water inlet connector installation, the installation angle can be adaptively adjusted by rotation, eliminating problems caused by hole tilt deviation and reducing potential risks such as leakage and structural instability. Furthermore, during installation, the contact surface 8 abuts against the wall surface 9, quickly ensuring the water outlet direction is perpendicular to the wall surface 9 without requiring multiple manual adjustments for leveling. This simplifies operation, reduces installation difficulty, improves assembly efficiency, and ensures normal product use.
[0048] Optionally, in some embodiments of this utility model, such as Figure 1As shown, the water inlet connector also includes a first sealing element 10, which is disposed between the spherical portion 6 and the spherical groove 7. Optionally, the first sealing element 10 is an O-ring, a V-ring, or the like. This arrangement allows the first sealing element 10 to effectively fill the tiny gap between the spherical portion 6 and the spherical groove 7, preventing water or other media from leaking from the connection point, thus improving the sealing performance and connection stability of the water inlet connector and reducing the risk of leakage and loosening.
[0049] Optionally, in some embodiments of this utility model, such as Figure 4 As shown, one of the spherical portion 6 and the spherical groove 7 is provided with an annular groove 11 adapted to the first sealing member 10, and the first sealing member 10 is embedded in the annular groove 11. That is, the annular groove 11 can be provided on the spherical portion 6; or, the annular groove 11 can be provided on the spherical groove 7. For example, as Figure 6 As shown, the spherical portion 6 is provided with an annular groove 11 that matches the first sealing element 10, and the first sealing element 10 is embedded in the annular groove 11. This arrangement provides a precise installation position for the first sealing element 10 through the annular groove 11, allowing it to be accurately positioned on the spherical portion 6, preventing displacement or misalignment. This ensures that the first sealing element 10 can better perform its sealing function between the spherical portion 6 and the spherical groove 7, effectively preventing media leakage.
[0050] Optionally, in some embodiments of this utility model, such as Figure 8 As shown, the connector 3 includes a connecting portion 301 and an abutting portion 302. Specifically, the connecting portion 301 has a cylindrical structure, as shown... Figure 7 As shown, the water inlet end 5 of the second connector 2 is provided with a first external thread 201, as... Figure 8 As shown, the inner wall of the connecting part 301 is provided with an internal thread 3011 that matches the first external thread 201, and the second connector 2 and the connecting piece 3 are connected as one unit through the threaded engagement. And as... Figure 3 As shown, the first connector 1 is inserted into the connecting part 301 to meet the installation and connection requirements of the first connector 1 and the second connector 2. Furthermore, as... Figure 3 and Figure 8 As shown, a spherical surface 3015 is provided at the position where the connecting part 301 contacts the first connector 1, so that the connecting part 3 can better fit with the first connector 1.
[0051] like Figure 8As shown, the abutment portion 302 is disposed on the side of the connecting portion 301 facing the wall surface 9. There are at least two abutment portions 302, each disposed circumferentially along the connecting portion 301, and each abutment portion 302 is provided with an abutment surface 8. It should be noted that the number of abutment portions 302 can be determined according to actual design requirements. Specifically, the abutment portion 302 can be a fixing plate, which can be integrally formed with the connecting portion 301 or assembled separately. Figure 2 As shown, the fixing plate is flush with the end face of the connecting part 301 so as to fit more tightly with the wall surface 9.
[0052] With this configuration, the connecting part 301 and the abutting part 302 work together to make the whole device a single unit, resulting in a more compact and stable structure. It also enables the joint to self-adapt to the wall surface, facilitating smooth product installation, avoiding multiple manual adjustments for leveling, and making operation convenient.
[0053] In addition, such as Figure 8 As shown, a second stepped surface 3014 is provided inside the connecting part 301. During installation, as... Figure 3 As shown, the second connector 2 is screwed into the connecting part 301 until it abuts against the second stepped surface 3014, thereby allowing for precise installation of the second connector 2, improving installation efficiency, and enhancing connection stability. Furthermore, as... Figure 7 As shown, the second connector 2 includes a first straight pipe 202 and a second straight pipe 203 connected to each other, and the first straight pipe 202 and the second straight pipe 203 are eccentrically arranged so as to adjust the outlet position according to the actual installation requirements.
[0054] Optionally, in some embodiments of this utility model, such as Figure 1 As shown, the water inlet connector also includes a limiting member 12. Optionally, the limiting member 12 is a pin. Figure 8 As shown, the inner wall of the connecting part 301 is provided with a first limiting groove 3012, such as Figure 6 As shown, the outer wall of the first connector 1 is provided with a second limiting groove 101 opposite to the first limiting groove 3012. Figure 3 As shown, one end of the limiting member 12 is inserted into the first limiting groove 3012, and the other end is inserted into the second limiting groove 101 to prevent relative rotation between the connecting part 301 and the first connector 1. This arrangement reduces unnecessary relative rotation between the connecting part 301 and the first connector 1. Thus, when installing the water inlet connector, rotating the connecting member 3 will rotate the entire device to connect with the water outlet connector, preventing the first connector 1 from spinning freely. It should be noted that a certain amount of clearance can be left between the limiting member 12 and the limiting groove to meet the rotation adjustment requirements during installation and avoid interference.
[0055] Optionally, in some embodiments of this utility model, such as Figure 8As shown, the outer wall of the connecting part 301 is provided with a polygonal structure 3013, such as a hexagonal structure. This design facilitates the use of tools such as hex wrenches, making operation easier and improving the flexibility and adaptability of installation.
[0056] Optionally, in some embodiments of this utility model, such as Figure 6 As shown, the inlet connector also includes a check valve 13, which is inserted into the first connector 1. The check valve 13 is located at the inlet end 5 of the first connector 1 and is unidirectionally open from the inlet end 5 to the outlet end 4. This configuration effectively prevents water from flowing back from the outlet end 4 to the inlet end 5, ensuring that the medium in the system flows in the predetermined direction, maintaining the normal operation of the system, and avoiding water pollution problems that may result from backflow.
[0057] Optionally, in some embodiments of this utility model, such as Figure 6 As shown, the water inlet connector also includes a filter screen 14, which is inserted into the first connector 1 and positioned at the water inlet end 5 of the check valve 13. Specifically, as... Figure 2 As shown, the water inlet connector also includes a retaining ring 16, and as... Figure 5 As shown, the first connector 1 has a first stepped surface 102 and an annular groove 104 inside. During installation, as... Figure 6 As shown, the check valve 13, filter screen 14, and retaining ring 16 are sequentially installed into the first connector 1, with the check valve 13 abutting against the first stepped surface 102, and the retaining ring 16 engaging in the annular groove 104, thereby achieving the installation and fixation of the check valve 13 and filter screen 14. This arrangement allows the filter screen 14 to filter the water entering the inlet connector, preventing impurities such as sediment and rust from entering the outlet device and causing pipe blockage, ensuring reliable operation of the device and extending its service life.
[0058] Optionally, in some embodiments of this utility model, such as Figure 6 As shown, the inlet connector also includes a second sealing element 15, which is disposed between the check valve 13 and the first connector 1. Optionally, the second sealing element 15 is an O-ring, a V-ring, or the like. The check valve 13 has a groove, and the second sealing element 15 is engaged in the groove. Alternatively, in some embodiments, a groove adapted to the second sealing element 15 can be provided on the inner wall of the first connector 1. With this configuration, the second sealing element 15 enables a sealed connection between the check valve 13 and the first connector 1, preventing leakage and ensuring reliable operation of the connector.

The derivation process of this beneficial effect is roughly similar to the derivation process of the beneficial effect of the water inlet connector described above, and therefore will not be repeated here.
