[0042] See also Figure 1 and Figure 3 As shown, according to an embodiment of the utility model, a shower head assembly is provided, including a detachably connected joint 1 and a shower head 2, a first connecting portion 3 is provided at one end of the joint 1 connected to the shower head 2, a second connecting portion 4 matching with the first connecting portion 3 is provided on the shower head 2, and the second connecting portion 4 can be rotatably connected to or disconnected from the first connecting portion 3, so that the shower head 2 can be installed on or removed from the joint 1.

[0043] Align the second connection part 4 with the first connection part 3, rotate the second connection part 4 to connect with the first connection part 3, and rotate it to the right position to connect the nozzle 2 with the pipe; when the nozzle 2 needs to be removed, rotate the second connection part 4 in the opposite direction to remove the nozzle 2 from the pipe. The utility model can flexibly replace the nozzle 2, so that the user can replace it according to the water pressure of the place where it is used, so as to ensure the spraying effect when washing clothes.

[0044] The first connection part 3 and the second connection part 4 can be snap-connected or threadedly connected. Specifically, when the nozzle 2 rotates clockwise, the second connection part 4 is connected to the first connection part 3; when the nozzle 2 rotates counterclockwise, the second connection part 4 is disconnected from the first connection part 3.

[0045] In this embodiment, the joint 1 is a hollow tube, the nozzle 2 is connected to the bottom end of the joint 1, and the inner diameter of the joint 1 is smaller than the inner diameter of the nozzle 2. The joint 1 is provided with an outer spray port 201, and the axis projection of the outer spray port 201 is approximately elliptical. When water flows, the water flows through the outer spray port 201 to form a fan-shaped spray surface, which can effectively cover the clothes in the washing drum and the washing doors and windows.

[0046] See also Figures 1 to 3 As shown, when the first connection part 3 and the second connection part 4 are connected by a snap-fit ​​connection, the first connection part 3 includes a clamping block 311, the clamping block 311 is arranged on the outer wall of the joint 1, the second connection part 4 is arranged on the inner wall of the nozzle 2, and the outer edge surface of the second connection part 4 has a clamping groove 411. The second connection part 4 rotates circumferentially relative to the clamping block 311 so that the outer edge surface of the clamping block 311 abuts against the clamping groove 411.

[0047] Specifically, the outer edge surface of the first connecting part 3 is an outwardly convex arc surface, and the clamping groove 411 is a concave arc surface toward the second connecting part 4. When the nozzle 2 is rotated clockwise, the first connecting part 3 is rotated and clamped in the clamping groove 411. When the nozzle 2 is rotated counterclockwise, the first connecting part 3 is rotated out of the clamping groove 411.

[0048] The first connection part 3 also includes a positioning buckle 312, which is arranged on the outer wall of the joint 1. The outer edge surface of the clamping block 311 also has a positioning groove 412. The second connection part 4 rotates circumferentially relative to the clamping block 311 and the positioning buckle 312. The clamping block 311 and the positioning buckle 312 are respectively abutted against the clamping groove 411 and the positioning groove 412, so that the clamping block 311 and the positioning buckle 312 limit the second connection part 4 circumferentially and axially.

[0049] As a specific embodiment, the second connection part 4 is block-shaped and arranged on the inner wall of the nozzle 2, and the positioning buckle 312 is arranged above the buckle, and the distance between the positioning buckle 312 and the buckle can clamp the second connection part 4. When the nozzle 2 is rotated clockwise, the second connection part 4 gradually approaches the positioning buckle 312 and the clamping block 311, until the clamping block 311 is clamped in the clamping groove 411 and the positioning buckle 312 is clamped in the positioning groove 412, then the rotation of the nozzle 2 is stopped, and the nozzle 2 and the joint 1 are installed in place; the nozzle 2 is rotated counterclockwise, and when the clamping block 311 is unscrewed from the clamping groove 411 and the positioning buckle 312 is unscrewed from the positioning groove 412, the nozzle 2 is separated from the joint 1, and the nozzle 2 is removed from the joint 1. By setting the positioning buckle 312 and the clamping block 311, the utility model can fix the nozzle 2 in the joint 1 to prevent the nozzle 2 from falling off, and the disassembly and installation process is simple to operate.

[0050] The outer wall of the joint 1 is provided with an annular groove 313, and a sealing member 314 for sealing the gap between the joint 1 and the nozzle 2 is provided in the annular groove 313. Specifically, the sealing member 314 is a sealing ring, and before installing the nozzle 2, the sealing member 314 is first installed in the annular groove 313, and when the nozzle 2 is connected to the joint 1, water is prevented from flowing out from the connection between the nozzle 2 and the joint 1.

[0051] See also Figures 4 to 6 As shown, when the first connection part 3 and the second connection part 4 are threadedly connected, the first connection part 3 is an external thread section 321, and the second connection part 4 is an internal thread section 421, and the first connection part 3 and the second connection part 4 are threadedly connected.

[0052] The outer wall of the joint 1 is provided with a clamping rib 322, which is located above the first connecting part 3. The top of the nozzle 2 is provided with a positioning rib 422, which can be aligned with the clamping rib 322 to indicate the connection depth between the second connecting part 4 and the first connecting part 3.

[0053] Specifically, when the nozzle 2 rotates clockwise, the connection length between the first connection part 3 and the second connection part 4 gradually increases, and the connection depth between the first connection part 3 and the second connection part 4 is determined by determining the position of the clamping rib 322 relative to the positioning rib 422 .

[0054] As a specific implementation method, in order to meet different spray water needs, there are two ways to adjust the opening of the external spray port 201. One is that the spray head assembly is equipped with a spray head 2 with different opening specifications, and different spray water needs are met by disassembling the spray head 2. The other way is that an opening adjustment part 5 connected to the joint 1 is provided in the spray head 2.

[0055] See also Figures 7 to 10As shown, one end of the opening adjusting member 5 is connected to the nozzle 2 and abuts against the joint 1, and the other end of the opening adjusting member 5 extends to the outer spray port 201. The opening adjusting member 5 can be deformed by the extrusion of the joint 1 to adjust the caliber of the outer spray port 201. In this embodiment, the opening adjusting member is made of rubber material, which can produce a certain deformation during the process of force extrusion. The main body of the opening adjusting member 5 is slightly thicker, while the thickness of the inner spray port 501 is slightly thinner. Within the adjustable range, the inner spray port 501 is deformed first in the nozzle 2.

[0056] The opening adjustment member 5 has an inner spray port 501, which fits the outer spray port 201, and the inner spray port 501 is forced to close in the direction of the outer spray port 201. In this way, the opening size of the outer spray port 201 can be adjusted by rotating the spray head 2 without replacing the spray head 2, which can ensure the use effect of the spray head in different use scenarios.

[0057] The inner wall of the nozzle 2 has a step structure, the step structure has a mating surface connected to the opening adjustment member 5, a limit block 502 is provided on the step structure, and a stopper 503 matching the limit block 502 is provided on the opening adjustment member 5. Since the deformation of the opening adjustment member 5 is subject to external force, the limit block 502 can prevent the opening adjustment member 5 from rotating relatively during the process of being squeezed by force.

[0058] As a specific embodiment, when the first connection part 3 is threadedly connected with the second connection part 4, the opening adjustment member 5 is first placed in the spray head 2, and then the spray head 2 with the opening adjustment member 5 is installed on the joint 1; since the opening adjustment member 5 has a certain hardness, when the spray head 2 is rotated clockwise until there is an obvious damping feeling, it means that the bottom end of the joint 1 has been in contact with the opening adjustment member 5, and the entire spray head assembly has been assembled; when the spray head assembly is installed on the washing machine for use, the user can observe the spray water curtain of the spray head 2 to determine whether the opening of the outer spray port 201 needs to be adjusted at this time. If the user needs to adjust the opening size of the outer spray port 201, the spray head 2 is continuously rotated, and the connection depth of the second connection part 4 and the first connection part 3 is determined according to the position of the clamping rib 322 relative to the positioning rib 422. In this process, the opening adjustment member 5 is subjected to the extrusion force applied by the joint 1, and the inner spray port 501 has a tendency to close, thereby realizing the opening size adjustment of the outer spray port 201.

[0059] As another specific embodiment, when the first connecting part 3 is snap-connected with the second connecting part 4, an opening adjustment part 5 can also be set in the nozzle 2. When the nozzle 2 is rotated clockwise and the second connecting part 4 component approaches the positioning buckle 312 and the block 311, the joint 1 squeezes the opening adjustment part 5 to adjust the opening size of the external spray port 201 within a small range.
