Technical Field

[0001] This utility model relates to the field of cleaning tools, and in particular to a high-efficiency mite-removing vacuum cleaner head. Background Technology

[0002] Vacuum cleaners are designed to remove dust and debris, cleaning even the smallest dust particles from corners, reducing housework stress and cleaning time. Vacuum cleaners are typically equipped with mite-removing brush heads to vacuum, sterilize, and remove mites from floors. Mites are microorganisms invisible to the naked eye; if not removed promptly, they can cause skin inflammation and respiratory allergies, harming human health. However, current mite-removing brush heads are inconvenient to clean regularly, making the brush head itself a source of contamination. Utility Model Content

The outer convex ring has at least two notches spaced apart in the circumferential direction. Each notch has an arc-shaped rib extending in the same circumferential direction on its outer side. One end of the arc-shaped rib near the circular end cap is connected to the outer convex ring, and the other end of the arc-shaped rib is a free end. A snap-fit ​​protrusion is provided on the outer surface of the arc-shaped rib, and at least two snap-fit ​​grooves that cooperate with the snap-fit ​​protrusion are provided on the inner wall of the annular seat.

[0005] The following are further improvements to the above technical solution: 1. In the above scheme, the driven bearing is an oil-impregnated bearing.

[0006] 2. In the above scheme, the annular seat is locked to the second mounting cavity of the housing by at least two screws.

[0007] 3. In the above scheme, the end face of the driven block away from the roller brush has an annular extension extending outward along the axial direction, which is embedded in the area surrounded by the inner and outer convex rings on the circular end cap.

[0020] Example 2: A high-efficiency mite-removing vacuum cleaner head includes: a housing 2 with a suction chamber 1 at the bottom, a suction pipe 22 communicating with the suction chamber 1 through an air inlet 21 opened on the upper part of the housing 2, and a roller brush 5 rotatably disposed in the suction chamber 1. The two ends of the roller brush 5 are respectively connected to a driving block 31 and a driven block 32. A first mounting cavity 33 and a second mounting cavity 34 are respectively disposed on the housing 2 and on both sides of the suction chamber 1. The driving block 31 is driven by a driving assembly 6 disposed in the first mounting cavity 33. The connection is as follows: an annular seat 35 is installed in the second mounting cavity 34; an inner convex ring 361 and an outer convex ring 362 are respectively provided on the surface of a rotatable circular end cap 36 facing the annular seat 35.

A driven bearing 37 is provided in the inner convex ring 361 on the circular end cap 36. The other end of a driven rotating shaft 38 connected to the driven bearing 37 is connected to the driven block 32 at one end of the roller brush 5. The outer convex ring 362 has at least two notches 39 spaced apart in the circumferential direction. Each notch 39 has an arc-shaped rib 40 extending in the same circumferential direction on its outer side. One end of the arc-shaped rib 40 near the circular end cap 36 is connected to the outer convex ring 362, and the other end of the arc-shaped rib 40 is a free end. A snap-fit ​​protrusion 43 is provided on the outer surface of the arc-shaped rib 40. The inner wall of the annular seat 35 has at least two snap-fit ​​grooves 44 that cooperate with the snap-fit ​​protrusion 43.

[0021] The driven bearing 37 is an oil-impregnated bearing; the driven block 32 has an axially outward annular extension 321 on the end face away from the roller brush 5, which is embedded in the area enclosed by the inner convex ring 361 and the outer convex ring 362 on the circular end cap 36.

[0022] The inner wall of the aforementioned annular seat 35 is provided with at least two arc-shaped protrusions 45 corresponding to the arc-shaped ribs 40, and the snap-fit ​​grooves 44 are formed on the arc-shaped protrusions 45; the end face of the arc-shaped protrusions 45 that mates with the free end of the arc-shaped ribs 40 is set as a slope surface.

The drive bearing 65 is a ball bearing.

[0024] When the roller brush needs cleaning after a period of use, or if the roller brush becomes stuck, simply rotate the circular end cap using the wrench slot. This will unscrew the locking protrusion that rotates with the circular end cap from the fixed locking groove, allowing the circular end cap to be removed. This facilitates the disassembly and reinstallation of the roller brush. When the roller brush is reinstalled, simply rotate the circular end cap in the opposite direction to re-engage the locking protrusion into the locking groove, thus securing the circular end cap and ensuring the stability of the driven bearing structure installed in the inner convex ring of the circular end cap. The arc-shaped rib with the locking protrusion is made of a plastic material with a certain degree of elasticity, and one end is a free end, which facilitates the installation and removal of the locking protrusion and the locking groove through the deformation and reset of the arc-shaped rib itself. The circular end cap and its inner convex ring, outer convex ring, and arc-shaped ribs are obtained through integral molding.

[0025] Using the aforementioned high-efficiency mite-removing vacuum head ensures the stability of the rotating structure of the roller brush during use, and facilitates the disassembly and installation of the roller brush. This allows for timely and convenient handling when the roller brush gets stuck, and also facilitates regular cleaning of the roller brush.
