Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a high-sealing dust collection bag fixing structure for a commercial waterless cleaning robot. Background Technology

[0002] In commercial waterless cleaning scenarios, the continuous and efficient operation of cleaning robots heavily relies on the reliable sealing of the dust collection system. As a core component for collecting dust and particulate matter, the insufficient sealing performance of the fixing structure between the dust bag and the main unit has become a key bottleneck restricting cleaning efficiency and equipment lifespan.

[0003] Currently, the dust bags of commercial waterless cleaning robots are typically fixed to the dust collection box of the main unit using simple clips, adhesives, or sleeves. However, in actual use, due to an unreasonable design of the fixing structure, sealing problems can easily occur. On the one hand, when the robot is running, a certain airflow pressure is generated in the dust collection chamber. If the sealing structure is insufficient, dust and fine particles may leak from the gaps between the dust bag and the fixing structure, which not only reduces dust collection efficiency but also contaminates the internal components of the robot, affecting the service life of the equipment. On the other hand, during the process of users replacing the dust bag, the unstable connection strength and sealing of the fixing structure may lead to leakage of residual dust, causing secondary pollution and adding an extra burden to the user's cleaning work.

[0004] In existing technologies, some dust bag fixing structures attempt to improve sealing performance by adding sealing strips and optimizing buckle shapes, but the following shortcomings still exist: for example, the sealing strips do not fit well with the fixing structure, and after long-term use, they are prone to aging and deformation, leading to sealing failure; the locking force of the buckles is uneven, which can easily cause local gaps; some structures are too complex, increasing the difficulty and cost of production and assembly, and also causing inconvenience to users.

[0005] Therefore, in response to the problems of dust leakage and insufficient sealing performance of existing dust bag fixing structures for robotic vacuum cleaners, there is an urgent need for a well-designed, reliable, and easy-to-operate high-sealing dust bag fixing structure to solve the problems of reduced cleaning efficiency, equipment contamination, and secondary pollution caused by dust leakage, thereby improving the user experience.

[0025] The above-mentioned and other technical features and advantages of this utility model will be described in more detail below with reference to the accompanying drawings.

[0026] Example 1

[0027] like Figure 1-2 As shown, this embodiment provides a high-sealing dust collection bag fixing structure for a commercial waterless cleaning robot, including a dust collection box 1, a negative pressure fan 2, a connecting component 3, and a dust collection bag 4. The negative pressure fan 2 is mounted on the dust collection box 1, with its air inlet connected to the interior of the dust collection box 1 and its exhaust outlet exposed to the external environment. The connecting component 3 is fixed to the left and right sides or bottom of the dust collection box 1. The dust collection bag 4 is mounted on the connecting component 3 and located inside the dust collection box 1. The negative pressure fan 2 draws air out of the dust collection box 1, creating a negative pressure inside. This allows dust and gas entering the dust collection bag 4 through the connecting component 3 to be filtered before entering the dust collection box 1, thus achieving dust filtration.

[0028] Reference Figure 3The connecting assembly 3 includes a connecting pipe 31, a sealing gasket 32, a connector 33, and a mounting housing 34. The connecting pipe 31 is disposed on one side of the connector 33, the sealing gasket 32 ​​is disposed between the connecting pipe 31 and the connector 33, the connector 33 is disposed within the mounting housing 34, the mounting housing 34 is disposed on the inner wall of the dust collection box 1, and the sealing gasket 32 ​​and the connecting pipe 31 are disposed on the outer side of the dust collection box 1. The sealing gasket 32 ​​improves the sealing performance between the connecting pipe 31 and the outer side of the dust collection box 1. The mounting housing 34 is fixed to the inner wall of the dust collection box 1 by welding or other methods. One side of the connector 33 has a screw hole that matches the flange on the connecting pipe 31. After the connector 33 is inserted into the mounting housing 34, screws can be used to fix the connector 33 and the connecting pipe 31 to the dust collection box 1.

[0029] Reference Figure 4 The dust collection bag 4 includes a mounting base plate 41, a raised ring 42, and a filter bag body 44. The filter bag body 44 is disposed on one side of the mounting base plate 41. The mounting base plate 41 has a through hole, and the raised ring 42 is disposed around the through hole. The mounting base plate 41 can be made of rigid cardboard or plastic sheet. The diameter of the through hole matches the diameter of the connecting pipe 31. The connecting member 33 has a mounting groove 331 that matches the mounting base plate 41. The side of the connecting member 33 has a mounting protrusion 332 that is coaxial with the raised ring 42. The raised ring 42 is pressed against the mounting protrusion 332. The raised ring 42 is made of rubber, and the elastic properties of the rubber are used to achieve a seal with the mounting protrusion 332.

[0030] In order to facilitate the replacement of the dust collection bag 4, a pull plate 43 is integrally formed on the mounting base plate 41. The pull plate 43 is provided with anti-slip texture. The mounting base plate 41 can be pulled out from the mounting groove 331 by pulling the pull plate 43.

[0031] To facilitate the installation of the mounting base plate 41, the edge of the raised ring 42 is chamfered, which reduces obstruction when the mounting base plate 41 is inserted into the mounting groove 331. After installation, the raised ring 42 and the mounting protrusion 332 are aligned and kept in compression. Furthermore, a maintenance hole is provided on the front or top surface of the dust collection box 1 to facilitate the maintenance of the dust collection bag 4.
