[0040] The following is combined Figures 1 to 8 This describes the valve body structure and water outlet device of an embodiment of the present utility model.

[0041] According to embodiments of this utility model, in one aspect, a valve body structure is provided, suitable for application in water outlet devices such as shower bodies, etc. Figure 1 As shown, the valve body structure includes a valve body 1 and a pipe connector 3. Specifically, as... Figure 7 As shown, the valve body 1 is provided with a water passage 101 and a second water outlet passage 103. The second water outlet passage 103 is coaxially arranged with the water passage 101 and connected to it. The outlet of the second water outlet passage 103 forms a demolding port 2.

[0042] like Figure 4 As shown, the pipe connector 3 has a bent structure, and the inlet end 4 of the pipe connector 3 is inserted into the second outlet passage 103. Clearly, the axis of the outlet end 9 of the pipe connector 3 is set at an angle to the axis of the water passage 101. It should be noted that, as shown... Figure 4 and Figure 7 Regarding the placement of the valve body structure shown, the left and right directions in the figure correspond to the axial directions of the water passage 101 and the second water outlet passage 103.

[0043] This design, by using the outlet of the second water outlet passage 103 as the demolding port 2, facilitates the demolding of the valve body 1 after injection molding, and then the pipe connector 3 is inserted into the second water outlet passage 103 to meet the application requirements of the water outlet component. This eliminates the need for a separate demolding port, forming an integrated design of demolding port and water outlet, greatly reducing the risk of leakage and the use of accessories such as plugs, thus lowering product costs.

[0044] Optionally, in some embodiments of this utility model, such as Figure 4 As shown, the valve body structure also includes a sealing element 5, which is sleeved on the water inlet end 4 of the pipe joint 3 and is located between the pipe joint 3 and the second water outlet passage 103. Optionally, the sealing element 5 is an O-ring, a V-ring, etc.

[0045] This configuration provides a reliable seal at the connection between the pipe joint 3 and the second water outlet passage 103 via the seal 5, preventing water leakage and ensuring normal fluid flow within the system. Furthermore, the seal 5 fits tightly between the pipe joint 3 and the second water outlet passage 103, filling any small gaps and improving the connection stability between the pipe joint 3 and the valve body 1.

[0046] Optionally, in some embodiments of this utility model, such as Figure 4As shown, one of the pipe connector 3 and the second water outlet passage 103 is provided with an annular groove 6 adapted to the sealing element 5, and the sealing element 5 is embedded in the annular groove 6. That is, the annular groove 6 can be provided in the pipe connector 3; or, the annular groove 6 can be provided in the second water outlet passage 103. For example, as Figure 8 As shown, the outer wall of the pipe joint 3 is provided with an annular groove 6 that matches the sealing element 5. During installation, the sealing element 5 is snapped into the annular groove 6.

[0047] With this design, the annular groove 6 provides a precise positioning space for the seal 5, ensuring that the seal 5 is in the correct position after installation and can tightly fit the contact surface of the pipe joint 3 and the second water outlet passage 103. This prevents the seal 5 from shifting during installation or use, ensures the reliability of the seal, and simplifies the installation process.

[0048] Optionally, in some embodiments of this utility model, such as Figure 4 As shown, the number of seals 5 is at least two, and each seal 5 is spaced apart along the axial direction of the water inlet end 4 of the pipe joint 3. It should be noted that the number of seals 5 can be determined specifically according to actual design requirements. For example, as... Figure 4 As shown, there are two seals 5, as follows. Figure 8 As shown, the outer wall of the pipe joint 3 is provided with two annular grooves 6, and the sealing element 5 is embedded in the annular groove 6 in a corresponding manner.

[0049] With this configuration, multiple seals 5 are spaced apart along the axial direction, forming multiple sealing lines. Even if one seal 5 fails to seal due to long-term use, wear, aging, or abnormal pressure impact, the other seals 5 can still continue to perform their sealing function, effectively preventing fluid leakage, improving sealing performance, and extending the overall service life.

[0050] Optionally, in some embodiments of this utility model, such as Figure 2 As shown, the valve body structure also includes a matching protrusion 7 and a groove 8. One of the water inlet end 4 of the pipe connector 3 and the second water outlet passage 103 is provided with a protrusion 7, and the other with a groove 8. The protrusion 7 is inserted into the groove 8. That is, the water inlet end 4 of the pipe connector 3 is provided with a protrusion 7, and the second water outlet passage 103 is correspondingly provided with a groove 8; or, the second water outlet passage 103 is provided with a protrusion 7, and the water inlet end 4 of the pipe connector 3 is correspondingly provided with a groove 8. For example, as... Figure 6 As shown, the second water outlet passage 103 is equipped with a corresponding slot 8, such as... Figure 8 As shown, the water inlet end 4 of the pipe connector 3 is provided with a corresponding protrusion 7, such as... Figure 3 As shown, protrusion 7 is inserted into slot 8.

[0051] This design ensures precise positioning of the connection between the protrusion 7 and the groove 8, allowing for accurate alignment of the inlet end 4 of the pipe connector 3 and the second outlet passage 103. During installation, the protrusion 7 smoothly inserts into the groove 8, ensuring accurate alignment and preventing loose connections or poor sealing due to installation deviations. Furthermore, the insertion of the protrusion 7 and the groove 8 enhances the connection strength between the pipe connector 3 and the valve body 1, ensuring they do not easily separate under fluid impact and guaranteeing safe system operation.

[0052] Optionally, in some embodiments of this utility model, such as Figure 8 As shown, there are at least two protrusions 7, evenly spaced along the circumference of the pipe joint 3, and the slots 8 correspond one-to-one with the protrusions 7. It should be noted that the number of protrusions 7 and slots 8 can be determined according to actual design requirements. For example, as... Figure 8 As shown, there are two protrusions 7, which are symmetrically arranged on the outer wall of the pipe connector 3. Correspondingly, there are two slots 8 on the second water outlet passage 103, and the slots 8 correspond one-to-one with the protrusions 7.

[0053] This configuration, with multiple protrusions 7 evenly spaced along the circumference of the pipe joint 3, achieves multiple circumferential connections and fixation, effectively resisting fluid impact and making the connection more robust and reliable, thus improving connection strength. Furthermore, the simultaneous bearing of the forces on the connection points by multiple protrusions 7 reduces the stress on individual protrusions 7, thereby ensuring the long-term stability of the connection.

[0054] Optionally, in some embodiments of this utility model, such as Figure 8 As shown, pipe fitting 3 includes a first straight pipe 301 and a second straight pipe 302. (As...) Figure 4 As shown, the first straight pipe 301 is coaxially arranged with the water passage 101, and one end of the first straight pipe 301 is inserted into the second water outlet passage 103. Figure 8 As shown, one end of the second straight tube 302 is bent and connected to the other end of the first straight tube 301. Optionally, the second straight tube 302 and the first straight tube 301 are bent and connected at a 90-degree angle. Furthermore, the first straight tube 301 and the second straight tube 302 can be integrally injection molded. Figure 8 As shown, the other end of the second straight pipe 302 is provided with a pipe connection part 3021. Optionally, the pipe connection part 3021 is provided with a pipe thread so as to quickly connect with the water outlet component through the thread.

[0055] This configuration, through the cooperation of the first straight pipe 301 and the second straight pipe 302, facilitates connection and fixation with the valve body 1. The bending design provides installation convenience for the pipe connector 3. The outlet direction of the pipe connector 3 can be flexibly adjusted according to the actual water circuit layout and installation position, which improves the versatility and adaptability of the pipe connector 3 and makes the water circuit layout in the valve body more compact and reasonable.

[0056] Optionally, in some embodiments of this utility model, such as Figure 8 As shown, the pipe fitting 3 also includes a reinforcing rib 303. One end of the reinforcing rib 303 is connected to the first straight pipe 301, and the other end is connected to the second straight pipe 302. This configuration, because the bends in the first straight pipe 301 and the second straight pipe 302 are prone to bending deformation, forms a triangular support structure through the reinforcing rib 303. This significantly improves the bending resistance of the pipe fitting 3, enhances its structural strength and stability, significantly extends its service life, and reduces damage and wear caused by external forces, pressure, and vibration during long-term use, thereby lowering maintenance costs and replacement frequency.

[0057] Optionally, in some embodiments of this utility model, such as Figure 7 As shown, the valve body 1 also has a first water outlet passage 102 connected to the water passage 101, and the axis of the first water outlet passage 102 is set at an angle to the axis of the water passage 101. Optionally, the first water outlet passage 102 is a water distribution valve chamber, and the axis of the first water outlet passage 102 is perpendicular to the axis of the water passage 101. In this way, the first water outlet passage 102 and the second water outlet passage 103 cooperate to meet the usage requirements of different water outlet components. In addition, as Figure 4 As shown, the axis of the water outlet 9 of the pipe connector 3 is parallel to the axis of the first water outlet passage 102. This is beneficial for system layout, simplifies system structure, and facilitates later maintenance and repair.

[0058] like Figure 4 As shown, the valve body 1 is also provided with a third water outlet passage 104 that is coaxially arranged and connected to the water passage 101. Figure 5 As shown, the third water outlet passage 104 and the second water outlet passage 103 are respectively located on both sides of the water passage 101. Figure 2 As shown, a pipe fitting 3 is inserted into the third water outlet passage 104. It is understandable that, as... Figure 4 As shown, the specific arrangement of the third water outlet passage 104 on the right and the pipe connector 3 can refer to the structural form of the second water outlet passage 103 on the left and the pipe connector 3. In this way, the pipe connectors 3 on both sides, together with the first water outlet passage 102, can form multiple water outlet channels to connect multiple water outlet components. Furthermore, the number of first water outlet passages 102 can be one, two, or more, and its number can be determined according to actual design requirements. It should be noted that, as shown in the example... Figure 4 and Figure 7 Regarding the placement of the valve body structure shown, the left-right direction in the figure is the axial direction of the third water outlet passage 104, and the up-down direction in the figure is the axial direction of the first water outlet passage 102.

[0059] With this configuration, pipe fittings 3 are inserted into the two ends of the water passage 101 of the valve body 1, so that the valve body 1 and the two side pipe fittings 3 can be assembled after being formed separately, reducing processing difficulty and manufacturing cost. Moreover, the valve body 1 and the pipe fittings 3 can be processed at the same time, realizing parallel production and improving production efficiency.

[0060] According to an embodiment of the present invention, another aspect provides a water outlet device, including the valve body structure as described in the various embodiments above. The derivation process of this beneficial effect is roughly similar to the derivation process of the beneficial effect of the valve body structure described above, and therefore will not be repeated here.

[0061] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
