[0037] like Figures 1-4 As shown, this utility model embodiment provides a water suction nozzle assembly structure, including a connecting pipe 1, a connector 2, and a mounting cover 3. One end of the connector 2 is connected to one end of the connecting pipe 1, and the outer wall of the other end of the connector 2 is provided with a guide post 23 extending radially outward along the connector 2. The mounting cover 3 is cylindrical, and the outer wall of the mounting cover 3 is provided with a mounting groove 31 corresponding to the guide post 23, and the mounting groove 31 is Z-shaped. Specifically, as... Figures 8-10 As shown, the mounting groove 31 includes a first groove 311, a second groove 312, and a third groove 313 that are connected perpendicularly to each other in sequence. The first groove 311 extends axially from one end of the mounting cover 3 toward the connector 2 along the mounting cover 3, and the guide post 23 is engaged with the third groove 313.

[0038] The suction nozzle assembly structure provided in this embodiment of the utility model allows for easy installation of the mounting cover 3 and the connector 2. Simply align the mounting groove 31 on the mounting cover 3 with the guide post 23 on the connector 2, and perform a pressing-rotating-pressing operation on the mounting cover 3. This allows the guide post 23 to pass sequentially through the first groove 311, the second groove 312, and then engage with the third groove 313, thus completing the installation. This suction nozzle assembly structure eliminates the threaded connection required in the assembly process between the mounting cover and the threaded connector in the prior art, making installation simpler and more efficient.

[0039] In one embodiment of the present invention, the connector 2 includes a first connecting cylinder 21 and a second connecting cylinder 22. The first connecting cylinder 21 is connected to the connecting pipe 1, and the guide post 23 is provided on the outer wall of the second connecting cylinder 22.

[0040] As Figure 2 , Figure 6 , Figure 7 shown, in order to make the installation cover 3 and the connector 2 connection firm, in an embodiment of the utility model, the number of the guide column 23 is two, and opposite to be equipped with two sides of the second connecting barrel 22.

[0041] As Figure 1 , Figure 2 , Figure 8 , Figure 9 , Figure 11 shown, in order to filter the water in the suction connecting pipe 1, in an embodiment of the utility model, the installation cover 3 is equipped with annular limit plate 32 away from one end of the installation groove 31, and the inside of limit plate 32 is equipped with filter screen 33.The filter screen 33 is extruded between the second connecting barrel 22 and the limit plate 32, and the water inlet hole formed in the inside of the limit plate 32 is shielded, to carry out preliminary filtration to the water entering the connecting pipe 1, prevent silt and the like from blocking the connecting pipe 1.

[0042] In the installation process of filter screen 33, if filter screen 33 is put into installation cover 3, then installation cover 3 is screwed into the second connecting barrel 22 again, filter screen 33 is easy to fall or deform, influence filtration effect.Therefore, in a preferred embodiment of the utility model, the filter screen 33 is integrally formed with the installation cover 3, so that the filter screen 33 has no risk of falling out and deformation, and the quality is more reliable.In this embodiment, the material of the installation cover 3 can be PA66, ABS, PP and other plastics, and the material of the filter screen 33 can be stainless steel, which is integrally formed with the installation cover 3 by a mold.Further, the material of the connector 2 can be PA66, ABS and other plastics, which is integrally formed by a mold.

[0043] In order to avoid the end of the installation cover 3 and the inner wall of the container for placing and cleaning water to be attached, causing the water inlet of the installation cover 3 to be blocked, as Figures 1-4 , Figures 8-10 shown, in an embodiment of the utility model, the outside of the limit plate 32 extends along the axial direction of the installation cover 3 and is provided with an overhead column 34.The overhead column 34 can make the installation cover 3 and the inner wall of the container exist minimum gap, prevent the two from being attached and cause the water inlet to be blocked.

[0044] In order to facilitate the sliding of the guide column 23 in the installation groove 31, in an embodiment of the utility model, the inner diameter of the first groove 311 and the second groove 312 is greater than or equal to the outer diameter of the guide column 23, so that the guide column 23 and the first groove 311, the second groove 312 are gap fit, improve the smoothness of the guide column 23 sliding.

[0045] To achieve the engagement between the guide post 23 and the third groove 313, in one embodiment of this invention, the guide post 23 and the third groove 313 are fitted with an interference fit. Alternatively, the inner wall of the third groove 313 may protrude inward to form a limiting portion, the inner diameter of which is smaller than the outer diameter of the guide post 23. When the guide post 23 passes through the limiting portion, the guide post 23 and / or the limiting portion undergo elastic deformation. After the guide post 23 passes the limiting portion, its retraction is restricted by the limiting portion, thus completing the engagement with the third groove 313.

[0046] like Figures 1-7 As shown, in one embodiment of this utility model, an annular baffle 24 is provided between the first connecting cylinder 21 and the second connecting cylinder 22. The baffle 24 abuts against the end of the connecting pipe 1 to prevent the connector 2 from entering the interior of the connecting pipe 1 and to provide a certain sealing performance. Furthermore, the baffle is connected to a fixing clip 25 to hang the entire water suction nozzle assembly on the outer shell of the range hood.

[0047] In one embodiment of the present invention, the outer periphery of the first connecting cylinder 21 is provided with anti-slip grooves to improve the stability of the connection with the connecting pipe 1.

[0048] like Figures 1-4 As shown, in one embodiment of this utility model, the end of the connecting pipe 1 away from the connector 2 is provided with a bidirectional connector 4 for connecting the water inlet assembly of the range hood. Compared with the existing water inlet assembly structure, the water inlet assembly structure provided in this embodiment of the utility model has the following advantages: 1. The number of parts is reduced from 5 to 4, which can reduce costs. 2. The number of processes is reduced from 4 to 3, which can improve assembly efficiency.

[0049] This utility model also provides a range hood, including the above-described water inlet assembly structure. The range hood is equipped with a water inlet assembly, which is connected to the connecting pipe 1.

[0050] The water inlet assembly structure and range hood provided in this utility model embodiment integrate the filter screen 33 and the mounting cover 3 into one piece. At the same time, the connector 2 and the mounting cover 3 are designed as a mounting groove and guide post structure, which can prevent the filter screen 33 from falling off and deforming. The threaded connection is eliminated, making the installation simpler, reducing costs and improving assembly efficiency.

[0051] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
