Description

Technical Field

[0001] The present application relates to the field of vacuum cleaners, and in particular to a dust collecting port structure of a vacuum cleaner. Background Art

[0002] At present, the structures of the dust collection port of the dust collection base station of the vacuum cleaner on the market mainly include the dust cup cover turning outward and the dust cup cover turning inward. The dust cup cover turning inward is not fixed by a lock, and the dust cup cover is simply covered by the spring force of the dust cup cover. In this method, when the spring force of the dust cup cover is too large, the opening angle of the dust cup cover of the vacuum cleaner is small when collecting dust, which affects the dust collection effect. When the spring force of the dust cup cover is too small, the dust cup cover may leak from the dust cup cover when the vacuum cleaner is in use because the dust cup cover is not covered well, resulting in a bad user experience; when the dust cup cover turns outward, the dust cup cover is reset under the action of the torsion spring. However, the torsion spring will produce metal fatigue after long-term use, resulting in failure to fully reset. At the same time, under the action of gravity, the dust cup cover has a tendency to open, resulting in the dust cup cover not being able to be completely closed, and garbage is easy to leak through the dust cup cover.

[0003] Therefore, there is a need for a dust collecting port structure for a vacuum cleaner that can prevent the dust cup cover from not closing properly and causing garbage to leak through the dust cup cover after the vacuum cleaner has been used for a long time. Utility Model Content

[0028] Reference Figure 1-5 A dust collecting port structure of a vacuum cleaner includes: a dust cup 100, a base station dust suction pipe 101, a dust cup cover 102, a top opening boss 107, and a magnetic suction structure 106. The dust cup 100 is provided with an inner cavity opening downward, and the base station dust suction pipe 101 is provided with an inner cavity opening upward. The dust cup 100 is inserted into the base station dust suction pipe 101 for installation, so that the dust cup 100 can slide up and down relative to the base station dust suction pipe 101. The dust cup cover 102 is arranged at the opening of the inner cavity of the dust cup 100, and is used to cover the inner cavity of the dust cup 100. A mounting groove 105 is provided at one side of the lower edge of the inner cavity opening of the dust cup 100, and the mounting groove 105 is separated from the inner cavity of the dust cup 100 by a shell, and a cup cover rotating shaft 103 is rotatably connected in the mounting groove 105, and the cup cover rotating shaft 103 passes through the dust cup cover 102, so that the dust cup cover 102 can be turned over on the axis of the cup cover rotating shaft 103. The top opening boss 107 is fixed on the upper edge of the inner opening of the base station dust suction pipe 101 and is arranged at the lower side of the mounting groove 105, and the top opening boss 107 can be inserted into the mounting groove 105. A torsion spring 104 is sleeved on the cup cover shaft 103, and the two ends of the torsion spring 104 are respectively in contact with the dust cup cover 102 and the inner wall of the mounting groove 105.

[0029] The dust cup cover 102 includes: an opening portion 108 and a cover portion 109 respectively located on both sides of the cup cover rotation shaft 103, the opening portion 108 is located in the mounting groove 105, the opening portion 108 is located on the upper side of the opening boss 107, and the cover portion 109 covers the opening of the inner cavity of the dust cup 100. The opening boss 107 is inserted into the mounting groove 105 to push the opening portion 108, so that the cover portion 109 flips over, opens the inner cavity of the dust cup 100, and allows the garbage to fall into the inner cavity of the base station suction pipe 101.

[0030] A sealing flange 110 is provided at the inner edge of the inner cavity opening of the dust cup 100 , and the cover body 109 abuts against the sealing flange 110 . A sealing ring groove 111 extending along the sealing flange 110 is provided on the sealing flange 110 , and a sealing ring 112 is provided in the sealing ring groove 111 .

[0031] The magnetic attraction structure 106 includes: a first magnetic attraction component 113 and a second magnetic attraction component 114. The first magnetic attraction component 113 is arranged at the opening position of the inner cavity of the dust cup 100; the second magnetic attraction component 114 is arranged on the upper side of the dust cup cover 102. The first magnetic attraction component is set as a magnet, and the second magnetic attraction component 114 is set as an iron sheet. The sealing flange 110 is provided with a first magnetic attraction component positioning groove 115 located outside the sealing ring groove 111, and the first magnetic attraction component 113 is arranged in the first magnetic attraction component positioning groove 115. The first magnetic attraction component pressure cover 116 is fixedly installed on the first magnetic attraction component positioning groove 115 by screws, which is used to fix the first magnetic attraction component 113.

The dust cup cover 102 is provided with a second magnetic member positioning groove 117 , a glue containing groove 118 is provided on the lower wall of the second magnetic member positioning groove 117 , and the second magnetic member 114 is glued and fixed in the second magnetic member positioning groove 117 .

[0032] Working process: By pressing the dust cup 100 downward, the top-opening boss 107 abuts against the top-opening part 108, so that the dust cup cover 102 rotates and opens, which is convenient for dust collection. When the dust collection is completed, lift the dust cup 100 upward, first so that the top-opening boss 107 no longer abuts against the top-opening part 108, and the dust cup cover 102 is closed under the action of the torsion spring 104 to complete the opening and closing of the dust cup cover 102. When the dust cup cover 102 is closed, the suction force generated by the first magnetic suction piece 113 at the lower end of the dust cup 100 and the second magnetic suction piece 114 on the dust cup cover 102 ensures that the dust cup cover 102 and the sealing ring 112 under the dust cup 100 are tightly attached and have a certain pre-tightening force during the use of the vacuum cleaner, avoiding the appearance of gaps. Prevent garbage from leaking out of the dust cup cover 102. At the same time, avoid the problem of the dust cup cover 102 not closing in place due to insufficient elasticity of the torsion spring 104 due to long-term use.
