Description

Technical Field

[0001] This application relates to the field of vacuum cleaner technology. Background Technology

[0002] In a vacuum cleaner, the dust cup typically consists of a dust cup and a dust cover located at the bottom of the dust cup that can be opened and closed. When the dust cover is opened, the dust inside the dust cup can be removed. Commonly, one end of the dust cover is hinged to the bottom of the cup body, while the other end has a locking mechanism with the cup body. To ensure a proper seal between the dust cover and the dust cup when closed, a sealing ring is usually placed at the junction. Since most existing dust covers and dust cups only achieve an axial seal, the sealing effect is limited. When the dust cover is subjected to external forces from the dust cup (e.g., when the dust cup is in the negative pressure suction chamber generated by the vacuum station), tiny gaps can easily form between the cup body and the bottom cover. These gaps will cause abnormal noise when airflow passes through them, thus affecting the user experience. Utility Model Content

[0003] Based on the above-mentioned technical problems, the purpose of this application is to provide a vacuum cleaner with excellent sealing effect between the dust cover and the dust cup.

[0004] To achieve the above objectives, this application provides a vacuum cleaner with a dust collection cup. The dust collection cup includes a cylindrical cup body and a dust cover movably connected to the lower part of the cup body between an open position and a closed position. The cup body defines an axial center line, and the dust cover in the closed position passes through the axial center line. A sealing ring is installed inside the dust cover. A circumferentially extending annular rib is provided on the inner wall surface of the lower part of the cup body. When the dust cover is in the closed position, the sealing ring is in sealing contact with the rib. The rib has a lower surface perpendicular to the axial center line and a circumferential side surface centered on the axial center line. Both the lower surface and the circumferential side surface are in sealing contact with the sealing ring.

[0005] In the above technical solution, preferably, the lower surface and the circumferential side surface intersect.

[0006] In the above technical solution, preferably, the sealing ring provides a tight-fitting surface with an obtuse-angled longitudinal section, and the lower surface and the circumferential side surface are simultaneously in sealing contact with the tight-fitting surface.

[0007] In the above technical solution, preferably, the dust collection cup further includes a release button; the release button is disposed on the side wall of the cup body and is operable to release the dust cover.

[0008] In the above technical solution, preferably, the lower part of the release button is provided with a first hook, and the dust cover is provided with a second hook; when the dust cover is in the closed position, the first hook and the second hook engage with each other.

[0009] In the above technical solution, preferably, the middle part of the release button is rotatably supported on the side wall of the cup body.

[0010] In the above technical solution, preferably, a spring is provided between the upper part of the release button and the side wall of the cup body.

[0011] In the above technical solution, preferably, the dust cover has an annular protrusion inside, and the sealing ring is fitted onto the annular protrusion.

[0012] In the vacuum cleaner of this application, the lower part of the cup body is provided with a raised rib having an upper surface and a circumferential side surface. The upper surface and the circumferential side surface are arranged perpendicular to each other. By installing a sealing ring on the dust cover, the sealing ring can simultaneously and tightly fit the upper surface of the raised rib and its circumferential side surface, thereby achieving a bidirectional seal in both the axial and horizontal directions at the junction of the cup body and the dust cover, improving the sealing performance and sealing effect of the dust collection cup.

[0020] To explain in detail the technical content, structural features, achieved objectives and effects of the utility model, the technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0021] This application provides a vacuum cleaner, such as... Figure 1 , 2 As shown in Figure 4, the vacuum cleaner has a dust collection cup 10, which includes a cylindrical cup body and a dust cover 2 movably connected to the lower part of the cup body 1 between an open position and a closed position. The bottom of the cup body 1 has an opening 11, and the dust cover 2 is rotatably mounted at the opening 11. When the dust cover 2 is in the open position, the dust cover 2 moves away from the opening 11 so that the opening 11 is open; when the dust cover 2 is in the closed position, the dust cover 2 covers the opening 11, thereby sealing it with the cup body 1.

[0022] like Figure 2 , 3 As shown, the cup body 1 defines an axial centerline X1, and the dust cover 2 in the closed position passes through the axial centerline X1. A sealing ring 3 is installed inside the dust cover 2, and an annular rib 12 extending circumferentially is provided on the inner wall surface of the lower part of the cup body 1. When the dust cover 2 is in the closed position, the sealing ring 3 and the rib 12 are in sealing contact.

[0023] In this embodiment, the rib 12 has a lower surface 121 perpendicular to the axial centerline X1 and a circumferential side surface 122 centered on the axial centerline X1. When the dust cover 2 is in the closed position, both the lower surface 121 and the circumferential side surface 122 are in sealing contact with the sealing ring 3. The sealing ring 3 provides sealing in both the horizontal and axial directions, improving the sealing effect of the dust collection cup 10.

[0024] like Figure 2 , 5 As shown, the lower surface 121 and the circumferential side surface 122 intersect. The sealing ring 3 provides a tight-fitting surface 31 with an obtuse-angled longitudinal section. The adjacent lower surface 121 and circumferential side surface 122 allow the tight-fitting surface 31 of the sealing ring 3 to simultaneously seal against both the lower surface 121 and the circumferential side surface 122. Part of the tight-fitting surface 31 abuts against the lower surface 121 to prevent air leakage in the axial direction, and part of the tight-fitting surface 31 abuts against the circumferential side surface 122 to prevent air leakage in the horizontal direction. The sealing ring 3 abuts against both the lower surface 121 and the circumferential side surface 122 simultaneously, achieving bidirectional sealing and improving sealing performance.

[0025] like Figure 3 , 6As shown, the dust cover 2 has an annular protrusion 21 inside. The sealing ring 3 is made of flexible material and is fitted onto the annular protrusion 21. The sealing ring 3 and the annular protrusion 21 are press-fitted, making it difficult for the sealing ring 3 to fall off the dust cover 2. In addition, when the dust cover 2 is closed, the sealing ring 3 and the rib 12 are press-fitted, further enhancing the sealing performance of the dust cup 10.

[0026] like Figure 2-5 As shown, the dust collection cup 10 also includes a release button 4, which is located on the side wall of the cup body 1 and is operable. The release button 4 releases the dust cover 2 from the closed position to the open position. The lower part of the release button 4 provides a first hook 41, and the dust cover 2 provides a second hook 22. When the dust cover 2 is rotated to the closed position, the first hook 41 and the second hook 22 engage with each other, thereby locking the dust cover 2 in the closed position. The middle part of the release button 4 is rotatably supported on the side wall of the cup body 1. When the upper part of the release button 4 is pressed, the release button 4 rotates, causing the lower first hook 41 and second hook 22 to disengage, allowing the dust cover 2 to rotate from the closed position to the open position, and the dust collection cup 10 is opened. A spring 5 is provided between the upper part of the release button 4 and the side wall of the cup body 1, facilitating the reset of the release button 4.
