[0025] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0026] like Figure 1-Figure 6 As shown, a water inlet sealing structure and a washing machine are provided. The water inlet sealing structure includes a water inlet box 1 and a water inlet valve 2. A sealing sleeve 3 is provided on the water inlet valve 2. The water inlet valve 2 is interference fit with the water inlet 101 of the water inlet box 1 through the sealing sleeve 3.

[0027] Specifically, the interference fit method is used instead of the traditional glue sealing, which simplifies the assembly process and avoids the leakage problem caused by uneven glue application. The use of the sealing sleeve 3 improves the sealing performance at the interface and reduces the risk of leakage that may occur in long-term use. The sealing sleeve 3 does not need to use glue sealing, making the disassembly and replacement of the components easier and faster, and facilitating repair and maintenance.

[0028] Further, if Figure 2 , Figure 5 and Figure 6 As shown, the water inlet valve 2 is provided with a connecting column 201 toward the water inlet direction of the water inlet box 1 , and the sealing sleeve 3 is sleeved on the connecting column 201 .

[0029] Further, if Figure 6 As shown, a recess 2011 is provided on the outer circumference of the connecting column 201 , and the sealing sleeve 3 is fixedly arranged on the recess 2011 .

[0030] Specifically, the recess 2011 provides a specific fixed position for the sealing sleeve 3, so that the sealing sleeve 3 can be accurately positioned during installation, thereby avoiding the problem of the sealing sleeve 3 slipping or loosening.

[0031] Further, if Figure 2 , Figure 5 and Figure 6As shown, a blocking portion 2012 is provided on one end of the connecting column 201 , and a positioning ring 302 extending outward is provided on one end of the sealing sleeve 3 , and the positioning ring 302 abuts against the blocking portion 2012 .

[0032] Specifically, the blocking portion 2012 can prevent the sealing sleeve from excessively moving or falling off, thereby ensuring that it is in the correct position and preventing water leakage.

[0033] Further, if Figure 2 , Figure 5 and Figure 6 As shown, a step 2013 is provided on the other end of the connecting column 201 , and the other end of the sealing sleeve 3 abuts against the step 2013 .

[0034] Specifically, by respectively providing the blocking portion 2012 and the step 2013 at both ends of the connecting column, the sealing sleeve 3 is supported and positioned at both ends.

[0035] Further, if Figure 2 , Figure 5 and Figure 6 As shown, a guiding inclined surface 2014 is provided on the other end of the connecting column 201 , and the connecting column 201 is inserted into the water inlet 101 of the water inlet box 1 through the guiding inclined surface 2014 .

[0036] Specifically, the connecting column 201 can reduce friction and alignment difficulties during installation through the guiding slope 2014, so that the connecting column 201 can be inserted into the water inlet 101 of the water inlet box more smoothly.

[0037] Further, if Figure 2 , Figure 5 and Figure 6 As shown, a plurality of raised sealing ribs 301 are provided on the sealing sleeve 3 , and the plurality of sealing ribs 301 are evenly spaced and arranged in an outer circumferential direction of the sealing sleeve 3 along a length direction of the sealing sleeve 3 .

[0038] Specifically, the plurality of raised sealing ribs 301 can provide additional friction on the contact surface, thereby enhancing the sealing performance and ensuring a tighter seal at the interface.

[0039] Furthermore, a multiple sealing structure is formed between the sealing rib 301 and the water inlet 101 of the water inlet box 1 .

[0040] Specifically, the multiple sealing structures between the sealing rib 301 and the water inlet 101 of the water inlet box 1 enable each layer to compensate for minor errors during installation, thus helping to prevent water leakage.

[0041] Further, if Figure 2 As shown, the sealing rib 301 gradually increases in inclination from the water inlet 101 toward the water inlet valve 2 on the sealing sleeve 3 .

[0042] Specifically, the gradual enlargement and inclined setting of the sealing rib 301 helps to provide a tighter contact surface during connection, and can provide a more effective sealing effect.

[0043] A washing machine comprises a machine body, on which the water inlet sealing structure is arranged.

[0044] Specifically, the washing machine has a water inlet sealing structure to reduce the risk of water leakage and improve the convenience of assembly, thereby increasing the reliability and durability of the product.
