Furthermore, those skilled in the art may combine and integrate different embodiments or examples, and features of different embodiments or examples, described in this specification, unless they are mutually inconsistent.

[0037] In order to illustrate the technical solution of the present invention, specific embodiments are provided below. Example 1

[0038] like Figure 1-3 As shown, the present invention provides a snow brush, which includes a snow brush body 10, a moving wheel assembly and a connecting member 40. The moving wheel assembly is fixed to the snow brush body 10, and the connecting member 40 is provided on the snow brush body 10. The number of the moving wheel assemblies is more than two.

[0039] The snow brush body 10 includes a first scraper 101 and a second scraper 102, which are connected to each other and arranged in a V-shape or L-shape. The first scraper 101 and the second scraper 102 together surround a snow brush inner space 103. The connector 40 is positioned within the snow brush inner space 103.

[0040] Preferably, the connecting member 40 is disposed at the geometric center of the connection between the first scraper 101 and the second scraper 102. This has the beneficial effect of making the overall force of the snow brush more balanced during snow removal, making it easier for the user to exert force.

[0041] Further preferably, the connector 40 is connected to the snow brush body 10 via reinforcing ribs 50. The number of reinforcing ribs is preferably four, and the plurality of reinforcing ribs are symmetrically arranged. The connector 40 is connected to the first scraper 101 via two reinforcing ribs at the upper end. The connector 40 is connected to the second scraper 102 via two reinforcing ribs at the lower end. The beneficial effect of providing the reinforcing ribs is that they strengthen the connection between the connector 40 and the snow brush body 10, thereby increasing the service life of the snow brush.

[0042] The connector 40 is detachably connected to the tool rod assembly. The connector 40 and the tool rod assembly can be connected by a threaded connection or a snap-on connection. Preferably, the connector 40 has an internally threaded connection. This internally threaded connection enables connection to a tool rod assembly having an externally threaded connection. The tool rod assembly is preferably a fixed-length straight rod or a telescoping straight rod.

[0043] The moving wheel assembly includes a wheel bracket 20 and a moving wheel 30. The moving wheel 30 is mounted on the outer side of the lower end of the second scraper 102 via the wheel bracket 20. There are at least two wheel brackets 20. The moving wheel 30 is mounted within the wheel bracket 20. The wheel bracket 20 is provided with symmetrically arranged axle brackets, and the moving wheel 30 is connected to the symmetrically arranged axle brackets via a wheel axle. A groove for accommodating the moving wheel 30 is also provided on the outer side of the lower end of the second scraper 102. Preferably, multiple moving wheel assemblies are evenly distributed along the length of the scraping edge of the lower end of the second scraper 102.

[0044] The outer side of the snow brush body 10 is provided with a plurality of reinforcing beams 110. The inner side of the snow brush body 10 is provided with a plurality of stepped portions 120. The stepped portions 120 are arranged alternately with the reinforcing beams 110. The plurality of reinforcing beams 110 are evenly arranged along the length of the snow brush body 10. The plurality of stepped portions 120 are evenly arranged along the length of the snow brush body 10. The beneficial effect of providing the reinforcing beams 110 is that it can increase the strength of the snow brush body 10 or achieve the lightweight of the snow brush body 10 without reducing the strength. The beneficial effect of providing the stepped portions 120 is that it reduces the flatness of the inner side of the snow brush body 10, allowing snow that contacts the inner side of the snow brush to be better separated from the snow brush, thereby increasing work efficiency and reducing unnecessary time spent cleaning the snow brush.

[0045] Preferably, the lower end of the first scraper 101 and the upper end of the second scraper 102 are integrally formed. The top of the first scraper 101 is the first scraping edge 104, and the bottom of the second scraper 102 is the second scraping edge 105. Users can choose to use the first scraping edge 104 or the second scraping edge 105 according to different scenarios. The second scraper 102 can be pointed downward to remove snow from the roof, while the first scraper 101 can also be pointed downward to remove snow from the roof. Further preferably, the second scraping edge 105 is straight, while the first scraping edge 104 is curved.

[0046] The utility model also provides a snow removal tool, which includes a snow brush and a tool rod assembly. The snow brush and the tool rod assembly are detachably connected.

[0047] The materials of the snow brush and tool pole assembly are usually selected from materials with low friction coefficient, such as smooth aluminum alloy or plastic, to reduce friction during operation, making the snow slide off more easily and reducing the labor intensity of the user.

[0048] In the application scenario where the user is on the ground to clear snow from the roof, the present invention also provides a method of using the snow removal tool as follows:

[0049] First, the length needs to be adjusted. The tool rod assembly should be extended or retracted as needed to make it long enough to reach the snow on the roof, but not too long to affect operation. Then, the snow brush body 10 with the second scraper 102 facing downward is inserted under the snow layer, close to the roof surface. Then, the snow removal tool is dragged towards the user with force, allowing the snow to slide down the snow brush to the ground. During the dragging process, the moving wheel assembly can contact the roof. The setting of the moving wheel assembly can reduce the friction between the snow brush and the roof structure. By using the moving wheel assembly, the user can drag the snow on the roof more smoothly and effortlessly. The moving wheel assembly can also prevent excessive force from scratching the roof material. The snow removal tool provided by the utility model is particularly suitable for roofs covered with solar panels. By repeating the above process, the entire roof can be gradually cleaned.

[0050] Of course, the snow removal tool of the present invention can be used in other ways. For example, when the user is on a roof, the outer side of the snow brush can be used to push snow off the roof. In this case, the user, located at a high location, inserts the snow brush body 10, with the second scraper 102 facing downward, under the snow layer, close to the roof surface, and firmly pushes the snow removal tool toward the user. During this pushing process, the moving wheel assembly can contact the roof. The provision of the moving wheel assembly reduces friction between the snow brush and the roof structure, making it easier and more effortless for the user to push snow off the roof. The moving wheel assembly also prevents excessive force from scratching the roof material. By repeating this process, the entire roof can be gradually cleaned.

[0051] Alternatively, you can prioritize snow removal with the first scraper 101. Due to the configuration of the moving wheel assembly, there may be a gap between the bottom of the second scraper 102 and the roof, which may result in some residual snow not being completely cleared. In this case, you can prioritize snow removal with the first scraper 101. The first scraping edge 104 of the first scraper 101 can be closer to the roof, and because the first scraping edge 104 is curved, it effectively clears snow from the roof.

[0052] In addition to being used in rooftop snow removal scenarios, the snow removal tool of the present invention can also be used for daily ground snow removal work. In ground snow removal work, the above-mentioned push or drag method can also be used. The specific content is not repeated again. Example 2

[0053] The difference between this embodiment and the first embodiment is that the tool rod assembly is a multi-section telescopic rod mechanism with a steering joint. Figures 4 to 12 As shown, the multi-section telescopic rod mechanism includes multiple telescopic rods 3. In each pair of telescopic rods 3 that are socketed with each other, a lock buckle 1 with an eccentric cam handle 2 is installed at the end of the thicker telescopic rod 3. The surface of the lock buckle 1 has a pair of arc-shaped abutting edges 11a. The cam portion on the eccentric cam handle 2 abuts against the abutting edges 11a. The outer sides of the pair of abutting edges 11a are each provided with a limiting plate 13. There is a gap between the limiting plate 13 and the side edge 21 of the eccentric cam handle 2, and the gap is configured to limit the deflection of the eccentric cam handle 2 relative to the lock buckle 1.

[0054] Combine Figure 4-5As shown, in this embodiment, the multi-section telescopic rod 3 mechanism includes five telescopic rods 3, each with an increasing inner diameter. The thicker telescopic rod 3 is nested within the thinner telescopic rod 3. In each pair of nested telescopic rods 3, a lock catch 1 is attached to the end of the thicker telescopic rod 3. Specifically, the multi-section telescopic rod 3 includes four lock catches 1 with eccentric cam handles 2. When the lock catches 1 are unlocked, the thinner telescopic rod 3 can be extended freely. When the lock catches 1 are locked, they lock the thinner telescopic rod 3, restricting its displacement relative to the thicker telescopic rod 3.

[0055] Further, combined with Figure 6-8 As shown, in this embodiment, the surface of the lock catch 1 is recessed downward to form an abutment edge 11a, and the surface profile of the abutment edge 11a is arcuate. An eccentric cam handle 2 is located on one side of the lock catch 1, and a nut is provided on the other side of the lock catch 1. The eccentric cam handle 2 is threadedly connected to the nut via a connecting shaft (not shown).

[0056] Specifically, combined Figure 8-10 As shown, the lock buckle 1 is integrally formed, and includes a clamping sleeve 11 and a fixing sleeve 12 in sequence along the axial direction. The fixing sleeve 12 is clamped on the end of the thicker telescopic rod 3, and the eccentric cam handle 2 is installed on the clamping sleeve 11 through a connecting shaft. The eccentric cam handle 2 has a pivot hole 22 for connecting the pivot, and the pivot is connected to the connecting shaft.

[0057] Furthermore, in this embodiment, the clamping sleeve 11 and the fixing sleeve 12 are integrally connected, and both are integrally formed with the locking buckle 1 through an injection molding process. The fixing sleeve 12 has an inner diameter larger than that of the clamping sleeve 11, and the fixing sleeve 12 is locked and fixed to the end of the telescopic rod 3 by a screw (not shown).

[0058] Specifically, combined Figure 11-12 As shown, the end of the frontmost telescopic rod 3 among the multiple telescopic rods 3 is fixedly installed with a joint connecting part 4, which includes a first joint 41, a second joint 42 and an adjusting knob 43 connecting the two. When the adjusting knob 43 is loosened, the first joint 41 can rotate relative to the second joint 42 around the central axis of the adjusting knob 43; when the adjusting knob 43 is locked, the angle of the first joint 41 relative to the second joint 42 is fixed. The first joint 41 has a first disc-shaped fixed block 41a, and the second joint 42 has a second disc-shaped fixed block 42a. The adjusting knob 43 passes through the hinge structure formed by the first fixed block 41a and the second fixed block 42a. The first fixed block 41a and the second fixed block 42a are respectively provided with a first gear ring 41b and a second gear ring 42b on the opposite sides. When the adjusting knob 43 is locked, the first gear ring 41b and the second gear ring 42b are engaged.

[0059] Furthermore, in this embodiment, the first joint 41 is clamped around the frontmost telescopic rod 3, meaning that the first joint 41 is fixedly mounted at the end of the thinnest telescopic rod 3 among the multiple telescopic rods 3. A first fixing block 41a is provided at the end of the first joint 41 away from the telescopic rod 3. The outer edge of the first fixing block 41a engages with the clamping structure of the first joint 41. Similarly, one end of the second joint 42 is a free end with a thread for attaching an external accessory, and the other end of the second joint 42 is provided with a second fixing block 42a. The first fixing block 41a has a first toothed ring 41b on its circular surface, while the second fixing block 42a has a second toothed ring 42b on its circular surface. Both the first and second fixing blocks 41a, 42a have through-holes in their centers, through which adjustment knobs 43 pass. Rotating the adjustment knob 43 releases or locks the hinge structure. When the hinge structure is released, the first and second toothed rings 41b and 42b disengage, allowing the first joint 41 to rotate relative to the second joint 42, thereby adjusting the angle of the external accessory. When the hinge structure is locked, the first gear ring 41 b engages with the second gear ring 42 b , and the first joint 41 is locked relative to the second joint 42 .

[0060] The snow removal tool of this embodiment has the beneficial effect of connecting multiple telescopic rods 3 to a snow brush via threaded free ends on the second joint 42 for external attachment. Because the multi-section telescopic rod mechanism with a steering joint can change the joint angle, the operator can adjust the angle of connection between the multiple telescopic rods 3 and the rake head during use. This expands the application scenarios of the snow removal tool of this utility model. The snow removal tool can adapt to different roof shapes and slopes, making it suitable for snow removal on roofs of various structures. Example 3

[0061] This embodiment differs from the second embodiment in that both the first scraping edge 104 and the second scraping edge 105 are equipped with electric heating devices, which are electrically connected to the power supply circuit. A space is provided within the tool bar assembly to accommodate the power supply circuit. A power interface or power supply device is provided at the rear end of the tool bar assembly. An external power source or power supply device supplies power to the electric heating device via the power supply circuit. The electric heating device has a heating function, melting snow through electrical heating, making it easier to insert the snow brush into the snow layer.

[0062] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications based on the present invention that solve essentially the same technical problems and achieve essentially the same technical effects are included within the scope of protection of the present invention.
