Description

Technical Field

[0001] This utility model relates to vacuum cleaner technology, specifically to a standing locking structure for a vacuum cleaner. Background Technology

[0002] A vacuum cleaner is a household appliance that uses aerodynamic principles to achieve efficient cleaning. Its core function is to create a partial vacuum environment to generate suction, sucking dust, hair, debris, and other impurities from floors, furniture, crevices, and other areas into a dust collection device. As an essential cleaning tool for modern households, it uses a motor-driven fan to rotate at high speed, creating a low-pressure zone inside the vacuum cleaner. Outside air, carrying dust, enters through the suction inlet under atmospheric pressure, and after passing through a multi-layer filtration system to separate impurities, clean air is discharged.

[0003] Structurally, a vacuum cleaner consists of four main parts: the power system, the filtration system, the dust collection device, and functional accessories. The power system typically uses a copper wire or aluminum wire motor; the former is more heat-resistant and has a longer lifespan, while the latter is less expensive. The filtration system includes a dust bag, a filter, and HEPA high-efficiency filter media. HEPA filters can intercept 99.97% of fine particles, making them particularly suitable for people with allergies. The dust collection device is usually a dust cup or dust bag design, with capacities ranging from 0.3L to several liters to suit different needs. Furthermore, accessories such as floor brushes, crevice tools, and brush heads allow the vacuum cleaner to deeply clean carpet fibers, furniture crevices, and even curtain surfaces.

[0004] Traditional vacuum cleaner push rods lack a reliable locking mechanism. When parked upright, they are easily tipped over by external forces such as collisions or uneven ground, leading to equipment damage or safety hazards. Existing technologies require manual operation of locking devices such as knobs or buckles to fix the push rod angle, and only support a limited number of preset angles, which cannot adapt to complex usage scenarios. Utility Model Content

[0005] The purpose of this invention is to provide a standing locking structure for a vacuum cleaner to address the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a standing locking structure for a vacuum cleaner, comprising a housing, wherein the inner side of the housing is provided with a negative pressure adsorption cleaning device for cleaning debris from floors and furniture surfaces, and further comprising:

[0007] A push rod is disposed on one side of the outer casing. The push rod is vertically positioned and is used to manually drive the outer casing to move. A rotating shaft is horizontally fixedly installed at the bottom end of the push rod.

[0008] A protective housing is disposed between the outer shell and the push rod. The protective housing is used to connect the outer shell and the push rod. The protective housing includes a lower protective housing, one side of which is fixedly connected to the outer shell, and the lower protective housing is rotatably connected to the rotating shaft.

[0009] A locking unit is disposed at one end of the rotating shaft. The locking unit is located inside the lower protective shell and can lock the rotating shaft.

[0010] Furthermore, the locking unit includes:

[0011] The first irregularly shaped block is fixedly installed at one end of the rotating shaft;

[0012] The second irregular block is snapped into the inside of the first irregular block, and a protrusion is provided on one side of the second irregular block;

[0013] The locking lever is snapped and fixedly installed inside the lower protective shell, with one bottom side of the locking lever abutting against the outer protrusion of the second irregular block.

[0014] Furthermore, the upper protective shell is snapped and fixed to the top of the lower protective shell, and the upper protective shell is also snapped and fixed to the outer shell.

[0015] Furthermore, the locking unit includes a limiting unit, which includes a polygonal shaft fixedly installed at one end of the rotating shaft. The outer side of the polygonal shaft is a regular polygonal columnar structure. Two opposing sides of the outer side of the polygonal shaft are provided with pressing blocks. One side of the pressing block is in contact with the outer side of the polygonal shaft. The pressing block has a C-shaped cross-section. A limiting block is provided on the inner side of the other side of the pressing block. One side of the limiting block is fixedly connected to the inner side of the lower protective shell. The top of the outer side of the limiting block is slidably connected to one side of the pressing block. The pressing block and the limiting block are provided with a plurality of elastic elements. The plurality of elastic elements are evenly distributed. One end of the elastic element is fixedly connected to one side of the limiting block, and the other end of the elastic element is fixedly connected to one side of the pressing block. The elastic element is used to push the pressing block so that the outer side of the pressing block is pressed tightly against the outer side of the polygonal shaft.

[0016] Furthermore, the lower protective shell is rotatably mounted with wheels on both opposite sides.

[0017] A vacuum cleaner includes a standing locking structure for a vacuum cleaner as described above.

[0018] Compared with the prior art, the present invention provides a standing locking structure for a vacuum cleaner. When the push rod is vertical, the elastic element pushes the C-shaped pressing block to press against the polygonal shaft plane area at the end of the rotating shaft, generating static friction to lock the rotating shaft. When the push rod rotates, the polygonal shaft edges push the pressing block away and compress the elastic element, and the rotating shaft regains its free rotation, realizing angle adaptive locking. In use, it can lock the push rod at a certain angle while adaptively adjusting the tilt angle during use. Attached Figure Description

[0029] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0030] Example 1:

[0031] Please see Figures 1-4 A standing locking structure for a vacuum cleaner includes a housing 1, with a negative pressure adsorption cleaning device for cleaning debris from floors and furniture surfaces disposed inside the housing 1, and further includes:

[0032] Push rod 2 is located on one side of housing 1. Push rod 2 is vertically positioned and is used to manually drive housing 1 to move. A rotating shaft is horizontally fixed at the bottom end of push rod 2.

[0033] A protective housing is disposed between the outer shell 1 and the push rod 2. The protective housing is used to connect the outer shell 1 and the push rod 2. The protective housing includes a lower protective housing 5. One side of the lower protective housing 5 is fixedly connected to the outer shell 1, and the lower protective housing 5 is rotatably connected to the rotating shaft.

[0034] The locking unit is located at one end of the rotating shaft and inside the lower protective shell 5. The locking unit can lock the rotating shaft.

[0035] The push rod 2 is used for hand-held movement and to move the outer shell 1. The outer shell 1 is used to install the vacuum cleaner's suction cleaning components. The bottom of the outer shell 1 always remains in contact with the ground during use. The pivot is rotatably connected to the lower protective shell 5. During use, the tilt angle of the push rod 2 relative to the outer shell 1 can be adjusted at any time. When the vacuum cleaner needs to be placed, the locking unit limits the pivot to prevent the pivot and push rod 2 from rotating, so that the push rod 2 always remains in a fixed position and prevents the push rod 2 from tipping over.

[0036] The locking unit includes:

[0037] The first irregularly shaped block 6 is fixedly installed at one end of the rotating shaft;

[0038] The second irregular block 7 is snapped into the inside of the first irregular block 6, and a protrusion is provided on one side of the second irregular block 7;

[0039] The locking lever 8 is snapped and fixedly installed inside the lower protective shell 5, with one bottom side of the locking lever 8 abutting against the outer protrusion of the second irregular block 7.

[0040] The first irregular block 6 has a roughly circular top on the outside and an open bottom on the outside. The second irregular block 7 has a circular top in cross-section and an M-shaped protrusion at the bottom. The locking tab 8 is locked inside the lower protective shell 5. One side of the locking tab 8 abuts against the outside of the second irregular block 7. The locking tab 8 is a metal sheet with elastic deformation. When the push rod 2 is placed vertically, the bottom of the locking tab 8 locks the inside of the M-shaped protrusion of the second irregular block 7, thereby locking the position of the second irregular block 7, making the rotating shaft stationary, and thus locking the push rod 2.

[0041] The upper protective shell 4 is snapped and fixed to the top of the lower protective shell 5, and the upper protective shell 4 is also snapped and fixed to the outer shell 1.

[0042] The lower protective shell 5 and the upper protective shell 4 are interlocked and fixed together. When maintenance is required, the upper protective shell 4 can be removed to expose the locking unit.

[0043] The lower protective shell 5 has wheels 3 mounted on both opposite sides.

[0044] The wheels 3 are used to reduce the contact area between the outer shell 1 and the ground when the vacuum cleaner is in use, thereby reducing friction and making the vacuum cleaner easier to use.

[0045] A vacuum cleaner includes a standing locking structure for a vacuum cleaner as described above.

[0046] When push rod 2 is vertical, the bottom of the elastic metal locking tab 8 is engaged with the inner side of the M-shaped protrusion of the second irregular block 7, forcing the second irregular block 7 to engage with the first irregular block 6 fixed to the rotating shaft, rigidly locking the rotating shaft; unlocking requires manually rotating push rod 2 to disengage the locking tab 8.

[0047] Example 2:

[0048] Please see Figures 5-7 This embodiment provides a technical solution based on embodiment one: the locking unit includes a limiting unit 9, the limiting unit 9 includes a polygonal shaft 91 fixedly installed at one end of the rotating shaft, the outer side of the polygonal shaft 91 is a regular polygonal columnar structure, and two opposing sides of the outer side of the polygonal shaft 91 are provided with pressing blocks 92, one side of the pressing block 92 is in contact with the outer side of the polygonal shaft 91, the pressing block 92 has a C-shaped cross section, and a limiting block 93 is provided on the inner side of the other side of the pressing block 92, one side of the limiting block 93 is fixedly connected to the inner side of the lower protective shell 5, the top of the outer side of the limiting block 93 is slidably connected to one side of the pressing block 92, and a plurality of elastic elements 94 are provided on the pressing block 92 and the limiting block 93, the plurality of elastic elements 94 are evenly distributed, one end of the elastic element 94 is fixedly connected to one side of the limiting block 93, and the other end of the elastic element 94 is fixedly connected to one side of the pressing block 92, the elastic element 94 is used to push the pressing block 92, so that the outer side of the pressing block 92 is pressed tightly against the outer side of the polygonal shaft 91.

[0049] The polygonal shaft 91 is a regular polygonal columnar structure with an even number of sides of ≥4. The pressing block 92 is pressed against the outer side of the polygonal shaft 91 by the elastic member 94, limiting the polygonal shaft 91. The limiting block 93 is used to restrict the pressing block 92 to move laterally along its outer side. When the push rod 2 drives the polygonal shaft 91 to rotate through the pivot under manual drive, the elastic member 94 is compressed, and the angle of the push rod 2 is adjusted. When the push rod 2 needs to be placed vertically, it is only necessary to place the push rod 2 vertically, and the elastic member 94 drives the pressing block 92 to press against the outer side of the polygonal shaft 91, thereby locking the push rod 2. The elastic member 94 includes, but is not limited to, a spring with elastic deformation.

[0050] When push rod 2 is vertical, elastic element 94 pushes the C-shaped cross-section pressing block 92 to press the polygonal shaft 91 plane area at the end of the rotating shaft, generating static friction to lock the rotating shaft; when push rod 2 swings, the edges of polygonal shaft 91 push the pressing block 92 away and compress elastic element 94, the rotating shaft regains its rotational freedom, and the angle adaptive locking is achieved.

[0051] Working principle: During use, the movement of the vacuum cleaner is controlled by the linkage between the push rod 2 and the outer shell 1. When parked, the push rod 2 is locked in a vertical position to achieve autonomous standing. In the moving state, the user holds the push rod 2 and applies pushing force. The horizontal pivot at the bottom of the push rod 2 rotates freely within the lower protective shell 5, allowing the push rod 2 to tilt forward or backward to adjust its angle. The pushing force is transmitted to the outer shell 1 through the protective shell, driving the vacuum cleaner to move as a whole. At this time, the wheels 3 installed on both sides of the lower protective shell 5 contact the ground and roll, reducing the frictional resistance between the outer shell 1 and the ground. In the standing state, the user adjusts the push rod 2 to a vertical position. The locking unit acts on the pivot to restrict its rotation, fixing the push rod 2 as a vertical support rod, forming a stable triangular support structure with the bottom of the outer shell 1 to prevent the vacuum cleaner from tipping over.

[0052] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
