In this embodiment, the water inlet joint 21 has a substantially circular cross-section, and the water inlet joint 21 is connected to an external water supply line and a spray arm, respectively.

In one embodiment, the spacing corners 221/222 are formed on the outer edge of the spacing ledge 22. Specifically, the first and second limiting corners 221 and 222 are formed at the outer edge of the limiting ledge 22. The outer edge of the retaining rim 22 here refers to the surface of the retaining rim 22 facing away from the water inlet connector 21. In this embodiment, the strength of the water inlet connector 21 can be enhanced by the arrangement of the limiting convex edge 22, so that the first limiting notch 31 and the second limiting notch 13 abut against the limiting convex edge 22, and when the water inlet valve 20 is clamped, the water inlet valve 20 can be prevented from being broken due to an excessive clamping force. In addition, after the limiting convex edge 22 is arranged, the clamped position on the water inlet valve 20 can be better found, and the water inlet valve 20 can be quickly installed and positioned.

In other embodiments, a limiting groove may be formed on the outer circumferential surface of the inlet valve 20, the limiting member 30 is inserted into the limiting groove, and the first limiting notch 31 abuts against the bottom of the limiting groove.

Referring to fig. 6 again, the first limiting notch 31 has two adjacent first groove walls 32, and the two first groove walls 32 respectively abut against two adjacent side edges of the limiting convex edge 22. Specifically, one of the first groove walls 32 abuts the first side edge, and the other first groove wall 32 abuts the second side edge. Since the first side edge and the second side edge are 90 °, the included angle between the two first groove walls 32 is 90 °.

Referring to fig. 7 again, the second limiting notch 13 has two adjacent second groove walls 131, and the two second groove walls 131 respectively abut against two adjacent side edges of the limiting convex edge 22. Specifically, one of the second groove walls 131 abuts the third side edge, and the other second groove wall 131 abuts the fourth side edge. Since the third side edge and the fourth side edge are 90 °, the included angle between the two second groove walls 131 is 90 °. In addition, the second limit notch 13 may also have three or more second groove walls 131, a plurality of second groove walls 131 are connected in sequence, and each second groove wall 131 abuts against one side edge of the limit flange 22.

In one embodiment, the opening of the first restriction notch 31 faces the opening of the second restriction notch 13, so that the first restriction notch 31 and the second restriction notch 13 are respectively disposed at two opposite sides of the inlet valve 20 in the radial direction, and the forces applied to the inlet valve 20 are opposite, thereby restricting the inlet valve 20 from moving in the radial direction.

Referring to fig. 6 again, in an embodiment, the limiting member 30 is further provided with a reinforcing rib 33, and the reinforcing rib 33 extends along an edge of the first limiting notch 31. On the one hand, the rib 33 can provide structural reinforcement at the edge of the first restriction notch 31, so as to prevent the edge of the first restriction notch 31 from being deformed by the reverse force of the inlet valve 20. On the other hand, the rib 33 is disposed at the edge of the first limiting notch 31, and the notch formed by the surrounding of the rib 33 may form a part of the first limiting notch 31, that is, the rib 33 may abut against the first limiting corner 221, so as to increase the contact area between the limiting member 30 and the inlet valve 20, and to improve the engaging effect.

Referring to fig. 4, 9 and 10, in an embodiment, the chassis 10 has a mounting plate 11, the mounting plate 11 is formed with the mounting hole 12, the mounting plate 11 is provided with a boss 14, and one side of the boss 14 close to the mounting hole 12 is formed with the second limiting notch 13. In this embodiment, the mounting plate 11 may be a side wall of the chassis 10, and the boss 14 may be disposed on an inner side surface of the mounting plate 11. Alternatively, the boss 14 is integrally formed with the mounting plate 11. The boss 14 forming the second limit notch 13 is directly arranged on the mounting plate 11, and other parts are not needed, so that the structure is simplified. The provision of the boss 14 may also provide a local reinforcing effect on the strength of the mounting plate 11.

Referring to fig. 5 again, in order to limit the movement of the inlet valve 20 along the penetrating direction of the mounting hole 12, in an embodiment, two limiting convex edges 22 are axially spaced on the outer peripheral surface of the inlet connector 21, and the mounting plate 11 is inserted into a gap between the two limiting convex edges 22. In this embodiment, an insertion gap is formed between the two limiting convex edges 22, the mounting plate 11 at the hole edge of the mounting hole 12 is inserted into the insertion gap, and the mounting plate 11 abuts against the two limiting convex edges 22, so as to limit the movement of the inlet valve 20 in the penetrating direction of the mounting hole 12. In this embodiment, the mounting plate 11 is provided with a dowel 111, and the mounting plate 11 is inserted into the insertion gap through the dowel 111. In addition, in other embodiments, in order to limit the movement of the inlet valve 20 along the penetrating direction of the mounting hole 12, a slot may be formed on the mounting plate 11, and the limit flange 22 is inserted into the slot.

In addition, the limiting member 30 may have a tongue inserted into the insertion gap to limit the movement of the inlet valve 20 in the penetrating direction of the mounting hole 12.

In this embodiment, the first position-limiting notch 31 is engaged with one of the position-limiting protruding edges 22, and the second position-limiting notch 13 is also engaged with one of the position-limiting protruding edges 22. The stop ledges 22 cooperating with the first stop notch 31 and the second stop notch 13 may be one and the same.

In one embodiment, the limiting member 30, the water inlet joint 21 and the limiting ledge 22 cover the mounting hole 12 together, so that the mounting hole 12 is prevented from exposing other components in the chassis 10.

Referring to fig. 4 again, in an embodiment, the limiting member 30 is slidably connected to the chassis 10, wherein the sliding direction of the limiting member 30 can be along the opening direction of the first limiting notch 31, so that after the water inlet valve 20 extends into the installation hole 12, the limiting member 30 slides along the opening direction of the first limiting notch 31, so that the first limiting notch 31 is clamped at the first limiting corner 221 of the water inlet valve 20, thereby facilitating the engagement between the first limiting notch 31 and the water inlet valve 20, and the fixing of the water inlet valve 20 can be achieved without forcibly pressing the limiting member 30 and the chassis 10.

Specifically, two sliding grooves 15 are formed on the chassis 10, and the openings of the two sliding grooves 15 face each other, that is, the opening of one sliding groove 15 faces the opening of the other sliding groove 15, where the opening of the sliding groove 15 refers to an opening formed along the length direction of the sliding groove 15. Wherein, two sliding grooves 15 can be respectively arranged at two opposite sides of the mounting hole 12. The limiting member 30 is slidably connected to the sliding slots 15, so that the limiting member 30 is clamped between the two sliding slots 15, thereby limiting the movement of the limiting member in the opening direction of the sliding slots 15.

In order to prevent the limiting member 30 from moving, in an embodiment, the limiting member 30 is further connected to the chassis 10 in a snap-fit manner. Specifically, a buckle 34 may be disposed on the limiting member 30, and a slot for the buckle 34 to be clamped may be disposed on the chassis 10. Or, the limiting member 30 is provided with a slot, and the chassis 10 is provided with a buckle 34. Alternatively, the stopper 30 and the chassis 10 may be provided with a buckle 34 for clamping.

Referring to fig. 11 to 14, the following description will take the retaining member 30 with the buckle 34 as an example: the limiting member 30 is provided with a buckle 34 to be clamped with the chassis 10. The buckle 34 has an abutting surface 341, the abutting surface 341 deviates from the first limiting structure, and the abutting surface 341 abuts against the hole edge of the installation hole 12, so as to limit the movement of the limiting member 30 along the opposite direction of the sliding direction.

It should be noted that, since the snap 34 needs to be snapped into the mounting hole 12, it is conceivable that the mounting hole 12 is larger than the radial dimension of the fill valve 20, so that after the fill valve 20 is installed into the mounting hole 12, there is also a gap in the mounting hole 12 for the snap 34 to snap in.

In order to provide the latch 34 with greater elasticity and ensure that the latch 34 can be smoothly latched into the chassis 10, in an embodiment, the stopper 30 includes a stopper plate 35 and a resilient arm 36, one end of the resilient arm 36 is connected to the stopper plate 35, and the other end is a free end, and the free end can move relative to the stopper plate 35, and the latch 34 is disposed at the free end of the resilient arm 36. Of course, the limiting plate 35 can open the hole 351 of stepping down, the one end of elastic arm 36 is connected the hole edge of the hole 351 of stepping down, the free end of elastic arm 36 can be followed the direction of link up motion of the hole 351 of stepping down to make the buckle 34 stretch into in the hole 351 of stepping down or the protrusion outside the hole 351 of stepping down.

When the limiting member 30 slides along the opening direction of the first limiting notch 31, the elastic arm 36 is pressed by the mounting plate 11 on the chassis 10 and moves toward the side where the abdicating hole 351 is located, so as to avoid the interference between the buckle 34 and the mounting plate 11 and the influence on the sliding of the limiting member 30. After the buckle 34 on the limiting member 30 slides into the mounting hole 12, the elastic arm 36 recovers elastic deformation and springs out towards the mounting hole 12, and meanwhile, the abutting surface 341 on the buckle 34 abuts against the hole edge of the mounting hole 12 to limit the limiting member 30 from moving towards the direction away from the first limiting notch 31. At this time, the first stopper notch 31 abuts on the first stopper corner 221 of the inlet valve 20, and the stopper 30 is restricted from moving in the opening direction of the first stopper notch 31. Therefore, after the limiting member 30 slides in place, the design of the buckle 34 and the first limiting notch 31 limits the limiting member 30 to continue sliding along the sliding slot 15.

In one embodiment, the limiting member 30 includes a limiting plate 35, the limiting plate 35 has the first limiting notch 31, and the limiting plate 35 is slidably connected to the chassis 10; the snap 34 is provided on the surface of the limit plate 35 facing the mounting hole 12. The clip 34 further has a guide surface 342, the guide surface 342 extends along the opening direction of the first stopper notch 31, and the guide surface 342 is inclined near the stopper plate 35 in the opening direction of the first stopper notch 31. One side of the guide surface 342 may be connected to the contact surface 341, and the other side is located at one side of the contact surface 341 facing the first limit notch 31. The guide surface 342 is configured such that the catch 34 is smaller at the end near the first limit notch 31 and larger at the end away from the first limit notch 31, forming a wedge or triangle or trapezoid. On one hand, the guide surface 342 is in line contact with the mounting plate 11, so that the contact area between the guide surface 342 and the chassis 10 can be reduced, and the sliding resistance of the limiting member 30 can be reduced; on the other hand, the contact surface 341 can be prevented from coming out of engagement with the hole edge of the mounting hole 12 by securing a large width (width in the direction in which the mounting hole 12 penetrates) and having a large contact surface 341 area.

Referring to fig. 4 again, in an embodiment, the installation hole 12 has an introduction section 121 and a matching section 122, the distribution direction of the introduction section 121 and the matching section 122 is perpendicular to the through direction of the installation hole 12, and the water inlet valve 20 can extend into the introduction section 121 and be clamped into the matching section 122. The matching section 122 is connected with the leading-in section 121 through a limiting necking mouth 123, and the width of the limiting necking mouth 123 is smaller than the outer diameter of the water inlet connector 21 of the water inlet valve 20.

Specifically, during assembly, the inlet valve 20 extends from the leading-in section 121, and simultaneously, a limiting convex edge 22 also extends from the leading-in section 121, and then the inlet valve 20 is pressed against the limiting concave opening 123, so that the inlet valve 20 moves to the matching section 122, the inlet connector 21 of the inlet valve 20 is clamped in the matching section 122, and the inlet connector 21 and the matching section 122 are in interference fit or small clearance fit. The width of the limiting constriction 123 is small, so that the water inlet valve 20 is prevented from moving back to the introduction section 121 to some extent. Meanwhile, the two limiting convex edges 22 are respectively arranged at two opposite sides of the mounting plate 11, so that the mounting plate 11 is clamped between the two limiting convex edges 22, and the water inlet valve 20 is limited to move along the through direction of the mounting hole 12. The second limit corner 222 is engaged with the second limit notch 13 of the mounting plate 11. Then, the limiting member 30 slides along the sliding slot 15 until the first limiting notch 31 of the limiting member 30 is engaged with the first limiting corner 221, and meanwhile, the buckle 34 of the limiting member 30 abuts against the hole edge of the guiding section 121, at this time, the limiting member 30 stops sliding, and the first limiting notch 31 and the second limiting notch 13 cooperate to partially or completely surround the limiting convex edge 22, so as to prevent the water inlet valve 20 from rotating.

The above is only the optional embodiment of the present invention, and not the scope of the present invention is limited thereby, all the equivalent structure changes made by the contents of the specification and the drawings are utilized under the inventive concept of the present invention, or the direct/indirect application in other related technical fields is included in the patent protection scope of the present invention.
