Description

Technical Field

[0001] This utility model relates to the technical field of cleaning equipment component structure, and in particular to a side sealing structure for a water tank. Background Technology

[0002] Cleaning equipment such as vacuum cleaners, garment steamers, ironing machines, and fabric cleaning machines all have water tanks inside the main body. For non-removable water tanks, a water inlet assembly is required to connect to the water inlet pipe. For ease of disassembly, the water inlet assembly and the water inlet pipe are usually not directly fixed together, but rather use a plug-in structure. This inevitably creates gaps, allowing liquid to leak out into the main body during water filling or if the equipment is accidentally tipped over, potentially affecting other components. A sealing ring or rubber ring is usually installed at the plug-in end to create a seal, but this is generally a structure where the inner and outer edges are separately tightly fitted to the inner and outer walls of the connecting pipe and the water inlet pipe, respectively. The sealing effect is relatively weak, especially after long-term use, as displacement or aging can affect the sealing performance. Utility Model Content

The cleaning equipment includes a water tank 1, a water inlet assembly 3 for injecting liquid into the water tank 1, and a water tank cover 4 for sealing the water inlet assembly 3.

[0025] Water tank 1 has an inlet pipe 2 adapted to water inlet assembly 3. Water inlet assembly 3 has a connecting pipe 31 that is sleeved with water inlet pipe 2. A sealing element 5 is provided at the insertion end of water inlet pipe 2 and connecting pipe 31. The sealing element 5 seals at least one of the inner and outer walls of water inlet pipe 2 and connecting pipe 31, as well as the inner or outer wall of the other, to limit the flow of liquid outward from the gap between water inlet pipe 2 and connecting pipe 31.

[0026] Based on the above technical solution, the side sealing structure of the water tank is suitable for use in cleaning equipment. The cleaning equipment includes a water tank 1, a water inlet assembly 3, a water tank cover 4, a water inlet pipe 2, and a connecting pipe 31. A sealing element 5 is provided at the joint of the water inlet pipe 2 and the connecting pipe 31. The sealing element 5 seals the inner and outer walls of one of them, as well as the inner or outer wall of the other, so that the gap between the water inlet pipe 2 of the water tank 1 and the connecting pipe 31 of the water inlet assembly 3 is sealed from multiple directions, resulting in a better sealing effect.

[0027] In a preferred embodiment, specifically as follows: Figures 3 to 5As shown, the connecting pipe 31 is at least partially inserted into the water inlet pipe 2. The sealing member 5 is generally annular, and one end facing the water inlet pipe 2 has an annular groove 53. The open end of the water inlet pipe 2 extends into the annular groove 53, causing the sealing member 5 to seal the inner and outer walls of the water inlet pipe 2. The connecting pipe 31 passes through the central through hole of the sealing member 5 and extends into the water inlet pipe 2, causing the sealing member 5 to seal the outer wall of the connecting pipe 31. Further, the sealing member 5 includes an inner sealing ring 51 surrounding the central through hole and an outer sealing ring 52 located outside the inner sealing ring 51, and an annular groove 53 with a downward opening is formed between the inner sealing ring 51 and the outer sealing ring 52.

[0028] As another alternative implementation, the connecting pipe 31 is sleeved on the outer periphery of the water inlet pipe 2, the sealing member 5 has an annular groove 53 facing the water inlet pipe 2, and the open end of the water inlet pipe 2 extends into the annular groove 53. The outer edge of the sealing member 5 abuts against the inner wall of the connecting pipe 31, so that the sealing member 5 seals the inner and outer walls of the water inlet pipe 2 and abuts against the inner wall of the connecting pipe 31.

[0029] Alternatively, the connecting pipe 31 is sleeved on the outer periphery of the water inlet pipe 2, the sealing member 5 has an annular groove 53 facing the connecting pipe 31, and the open end of the connecting pipe 31 extends into the annular groove 53. The inner edge of the sealing member 5 abuts against the outer wall of the water inlet pipe 2, so that the sealing member 5 seals the inner and outer walls of the connecting pipe 31 and abuts against the outer wall of the water inlet pipe 2.

[0030] Alternatively, the seal 5 has a first annular groove facing the connecting pipe 31 and a second annular groove facing the water inlet pipe 2, with the open end of the connecting pipe 31 extending into the first annular groove and the open end of the water inlet pipe 2 extending into the second annular groove, causing the seal 5 to simultaneously seal the inner and outer walls of the water inlet pipe 2 and the connecting pipe 31.

[0031] Furthermore, the inlet pipe 2 and the connecting pipe 31 are coaxial, but can be as follows: Figure 3 The longitudinal arrangement in the middle can also be designed as a horizontal or inclined arrangement, and it is preferred that the connecting pipe 31 is located directly above or inclined above the water inlet pipe 2, but it is not limited to this.

[0032] In a preferred embodiment, the inner edge of the inner sealing ring 51 also has an annular flange 54 protruding inward to further enhance the sealing effect with the connecting pipe 31.

[0033] As a further preferred embodiment, the water inlet assembly 3 is also provided with an annular protrusion 32 arranged around the connecting pipe 31, and an annular groove 33 is formed between the outer wall of the connecting pipe 31 and the inner wall of the annular protrusion 32. The sealing member 5 is at least partially embedded in the annular groove 33 to obtain a more stable structure.

[0034] As a further preferred embodiment, the outer diameter of the opening end of the connecting pipe 31 is smaller than the inner diameter of the opening end of the water inlet pipe 2, and multiple annularly arranged support ribs 21 are formed on the inner wall of the water inlet pipe 2 to hold and support the connecting pipe 31, thereby making the insertion structure more stable. Furthermore, the inner diameter of the annular groove 33 is smaller than the outer diameter of the outer sealing ring 52, and the outer diameter of the connecting pipe 31 is larger than the inner diameter of the inner sealing ring 51, causing the sealing element 5 to be fitted into the annular groove 33 under compression, thereby achieving a better sealing effect. Furthermore, in the longitudinal direction, the longitudinal length of the outer sealing ring 52 is greater than the longitudinal length of the inner sealing ring 51.

[0035] Furthermore, the cleaning equipment is a fabric cleaning machine, which includes a main body for cleaning clothes or fabrics, a water tank 1 inside the main body, an end cap 6 on the main body, and a water inlet assembly 3 on the end cap 6. The water tank cover 4 is screwed onto the water inlet assembly 3.
