[0035] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features within these embodiments may be combined with one another, unless they conflict.

[0036] It should be noted that the illustrations provided in the following embodiments are merely schematic illustrations of the basic concept of the present invention. Therefore, the illustrations only show components related to the present invention and are not drawn according to the number, shape, and size of components in actual implementation. In actual implementation, the type, quantity, and proportion of each component may be changed at will, and the component layout may also be more complex.

[0037] A handheld snowplow is a device designed specifically for clearing snow. It's typically lightweight and suitable for clearing snow from yards, driveways, and sidewalks. A handheld snowplow typically consists of a snowplow head and a handle. The head is equipped with a rotating blade that scoops and throws snow. The snowplow's angle of release is determined by the relative angle between the head and the ground. The handle is typically fixed to the head, so the relative angle between the handle and the ground indirectly determines the snowplow's angle of release.

[0038] However, in actual use, the relative angle between the handle and the ground varies depending on the user's height. Due to the improperly designed mounting angles of the snowplow head and handle of existing handheld snowplows, the snowplow head cannot achieve the ideal snow-throwing angle for tall or short users, affecting snow removal efficiency. For example, for shorter users, the angle between the handle and the ground may be too small, resulting in the snowplow head's snow-throwing angle being too high. This situation prevents snow from being effectively thrown away from the cleaning area, reducing work efficiency. For taller users, the angle between the handle and the ground may be too large, resulting in the snowplow head's snow-throwing angle being too low. This can also cause snow to be thrown into the area near the device, preventing it from effectively clearing accumulated snow from the cleaning area. Therefore, the present invention improves the relative position of the snowplow head and handle to accommodate most users' heights, ensuring that the snow-throwing angle remains within an appropriate range, ensuring user comfort while improving snow-clearing efficiency.

[0039] See also Figure 1-13 As shown, the technical solution of the present invention is described in detail below with reference to specific embodiments:

[0040] See also Figure 1 、 2 As shown, the snowplow provided by an embodiment of the present invention includes a housing 10, a snow roller 20, and a handle 30. The housing 10 encloses a snowplow chamber. The snow roller 20 is rotatably disposed within the snowplow chamber for gathering and dispersing accumulated snow. The handle 30 is connected to the housing 10 and is provided with a control switch 31. The housing 10 also includes a guide surface 11 for directing the direction in which accumulated snow is dispersed. The handle 30 and the housing 10 are assembled such that when the housing 10 is in contact with the ground and the distance between the control switch 31 and the ground is 65 cm to 85 cm, the angle between the guide surface 11 and the ground is 35° to 55°. In a specific embodiment, the guide surface 11 can be, for example, the top wall of the snowplow chamber.

[0041] In a specific embodiment, the housing 10 may, for example, include a main body with a certain structural strength, and an outer shell arranged on the outside of the main body for decoration. The snow roller 20 may be made of metal material, or other composite materials, polymers, etc. with a certain strength; the handle 30 may be set as a rod-shaped mechanism, and a grip for easy handholding may be provided on the handle 30.

[0042] The present invention associates the installation position of the control switch 31 with the snow throwing angle. Positioning the control switch 31 65-85 cm above the ground accommodates most people's hand positions and ensures a comfortable user experience. Controlling the snow throwing angle to 35-55 degrees ensures that accumulated snow is thrown a sufficient distance. These two factors, when combined, ensure that most people can efficiently remove accumulated snow in a comfortable position while using the snowplow. In a further embodiment, to achieve a more optimal snow removal effect, when the housing 10 is in contact with the ground and the distance between the control switch 31 and the ground is 65-85 cm, the angle between the guide surface 11 and the ground is 45-55 degrees.

[0043] See also Figure 3 、 4 As shown in Figures 5 and 6, in an optional embodiment of the present invention, a snow roller 20 includes a rotating bracket 21 and a blade 22. The rotating bracket 21 is rotatably connected to the housing 10 via a rotating shaft. The blade 22 is mounted on the rotating bracket 21. The blade 22 has spiral portions 221 at both ends of the blade 22 in a first direction X. The two spiral portions 221 are smoothly connected at their adjacent ends to form a snow-throwing portion 222. The first direction X is parallel to the rotating axis of the snow roller 20. The design of the spiral portions 221 enables the blade 22 to more effectively gather snow to a central area during rotation. This spiral structure helps push snow along the length of the snow roller 20, concentrating it in the groove-shaped snow-throwing portion 222, thereby improving cleaning efficiency. In a preferred embodiment, the two spiral portions 221 are symmetrically arranged to ensure that the snow roller 20 maintains balance during operation. This symmetrical design reduces vibration of the snow roller 20, reduces wear on the machine, and increases its service life.

[0044] See also Figure 3 、 4 As shown, in an optional embodiment of the present invention, a snow guide plate 12 is provided on the guide surface 11. The surface of the snow guide plate 12 is perpendicular to the guide surface 11 and non-parallel to the first direction. At least two snow guide plates 12 are spaced apart along the first direction. The width of the end of the snow throwing portion 222, distal from the axis of the snow roller 20, in the first direction is less than the distance between the two outermost snow guide plates 12. The arrangement of the snow guide plates 12 and the angle between them and the first direction help accurately guide the direction of snow throwing. By using a suitable angle, the direction of snowflakes can be effectively controlled, ensuring that they are thrown to the intended area and reducing the amount of snow thrown to undesirable locations. The width of the end of the snow throwing portion 222, distal from the axis of the snow roller 20, in the first direction is less than the distance between the two outermost snow guide plates 12. This design ensures that most snow is guided to the desired direction by the snow guide plates 12, reducing the workload of secondary cleaning and making cleaning more efficient.

[0045] See also Figure 4 As shown, in an optional embodiment of the present invention, the rotating bracket 21 is provided with a flat portion 23, the blade 22 is mounted on the flat portion 23, and the snow throwing portion 222 and the flat portion 23 are enclosed to form a snow throwing trough 24. The snow throwing trough 24 formed by the snow throwing portion 222 and the flat portion 23 can effectively concentrate the accumulated snow in this area. This design helps to better control the flow direction and throwing effect of the accumulated snow, making snow disposal more efficient and precise.

[0046] See also Figure 4 、 5 As shown, in an optional embodiment of the present invention, the spiral portion 221 has a number of turns less than or equal to 0.5, and two blades 22 are provided, symmetrically arranged about the axis of the snow roller 20. Having fewer turns than or equal to 0.5 helps reduce the complexity of the snow handling process. Fewer turns allows for faster snow movement and avoids the problem of poor snow flow caused by excessive spirals. Fewer turns reduces operational resistance of the snow roller 20, resulting in lower power and energy consumption required for snow handling, thereby improving efficiency and potentially extending the life of the device. The two blades 22 are symmetrically arranged about the axis of the snow roller 20, ensuring more even snow handling. This symmetrical arrangement helps maintain balance and stability during snow throwing, ensuring even snow movement and distribution, thereby improving cleaning efficiency. The symmetrical arrangement of the blades 22 reduces unbalanced loads on the snow roller 20 during operation, reducing vibration and noise. This not only improves operational stability but also makes operation quieter and more comfortable. The design simplifies the complexity of the spiral portion 221 and the symmetrical arrangement of the blades 22, simplifying maintenance and adjustment. Users can more easily clean and replace the blades 22, reducing maintenance costs and workload. The symmetrical layout of the blades 22 more effectively pushes accumulated snow to the center of the snow roller 20 and helps form a stable snow flow, which helps improve overall snow throwing capacity and efficiency.

[0047] See also Figure 4 As shown, in an optional embodiment of the present invention, the projection of the edge of the blade 22, away from the axis of the snow roller 20, in the first direction is an arc-shaped structure with the axis of the snow roller 20 as the center. This allows the blade 22 to contact the snow more evenly. Especially when processing snow in corners, the arc-shaped design ensures that the snow is evenly cut and pushed across the entire width of the blade 22, which helps improve the cleaning effect and makes the snow removal more uniform and thorough.

[0048] See also Figure 2As shown, in an optional embodiment of the present invention, a snow shovel 13 is provided at the bottom of the housing 10. The snow shovel 13 is configured so that when the angle between the guide surface 11 and the ground is between 45° and 55°, the cutting edge of the front end of the snow shovel 13 is positioned below or in front of the axis of the snow roller 20. When the angle between the guide surface 11 and the ground is within the range of 45° to 55°, the snow shovel 13 can effectively contact the ground and clear snow. This angle design ensures that the snow shovel 13 clears at the optimal angle, improving the snow clearing effect.

[0049] See also Figure 13 As shown, in an optional embodiment of the present invention, reinforcing ribs 131 are provided on the rear side of the snowplow blade 13 and at both ends of the snowplow blade 13 in the first direction. The ribs 131 are plate-like structures perpendicular to the first direction. The plate-like ribs 131 significantly enhance the structural strength and rigidity of the snowplow blade 13. The ribs 131 provide support, effectively preventing deformation or damage to the snowplow blade 13, particularly at the rear side and ends of the snowplow blade 13, which are often subjected to significant operating pressure and wear.

[0050] See also Figure 6-12 As shown, in an optional embodiment of the present invention, the snow guide 12 is rotatably connected to the guide surface 11. The housing 10 is provided with an angle adjustment mechanism for adjusting the angle of the snow guide 12, as well as a locking mechanism for maintaining the snow guide 12 at a plurality of different angles. In actual use, the angle of the snow guide 12 can be adjusted according to the actual environment to distribute snow to a specific area.

[0051] See also Figure 6-12As shown, in an optional embodiment of the present invention, the angle adjustment mechanism includes a knob 121, a swing arm 123, and a connecting rod 122. The knob 121 is rotatably connected to the housing 10. An eccentric shaft 1211 is provided on the knob 121. A plurality of swing arms 123 are respectively rotatably connected to the rotation axis of each snow guide 12. Each swing arm 123 is hinged to the connecting rod 122. The eccentric shaft 1211 can be hinged to the connecting rod 122 or to one of the swing arms 123. In a preferred embodiment, to ensure that the rotation angle of the knob 121 is consistent with the rotation angle of the snow guide 12, the line connecting the center of the knob 121 to the center of the eccentric shaft 1211 is equal in length and parallel to the effective length of each swing arm 123. The effective length of the swing arm 123 refers to the length of the line connecting the center of the hinge axis between the swing arm 123 and the connecting rod 122 to the rotation center of the snow guide 12. In a specific embodiment, for example, a spline shaft can be provided on the snow guide 12, and a spline hole can be provided on the swing arm 123. The spline hole cooperates with the spline shaft to achieve synchronous rotation of the swing arm 123 and the snow guide 12. It should be understood that the connection between the swing arm 123 and the snow guide 12 is not limited to a single method. For example, in some other embodiments, the swing arm 123 can also be connected to the snow guide 12 via screws, or the swing arm 123 and the snow guide 12 can be configured as an integrated structure. The locking mechanism includes a latch 124 and a slot 125. The latch 124 is movably connected to the knob 121 along its radial direction. A plurality of slots 125 are provided on the housing 10 at intervals along the circumference of the knob 121. The knob 121 is provided with a drive mechanism for driving the latch 124.

The driving plate 1241 is fixedly connected to the latch 124, the driving pin 128 is fixedly connected to the driving seat 127, and the driving seat 127 is movably connected to the knob 121 so that the driving pin 128 can be displaced in the axial direction of the knob 121. The driving plate 1241 is provided with an inclined surface that cooperates with the driving pin 128 so that when the driving pin 128 is displaced in the axial direction of the knob 121, it can drive the driving plate 1241. and the latch 124 moves along the radial direction of the knob 121 toward the center of the knob 121; in some other embodiments, the positions of the drive plate 1241 and the drive pin 128 can also be interchanged, for example, the drive plate 1241 can be set on the drive seat 127, and the drive pin 128 can be set on the latch 124; an elastic element 126 is also provided between the latch 124 and the knob 121, and the elastic element 126 is assembled so that its elastic force can drive the latch 124 to move in a direction away from the center of the knob 121.In a specific embodiment, the drive seat 127 can be hingedly connected to the knob 121, for example. The operator can unlock the locking mechanism by pressing or pulling the drive seat 127. After the locking mechanism is unlocked, the knob 121 can be freely rotated to adjust the angle of the snow guide 12. After releasing the drive seat 127, the latch 124 is reinserted into the slot 125 under the action of the elastic element 126, thereby relocking the snow guide 12. It should be understood that the assembly method between the drive seat 127 and the knob 121 is not limited. For example, in some other embodiments, the drive seat 127 can also be slidably connected to the knob 121 along the axial direction of the knob 121.
