[0025] The technical solution of the present application is further explained below in conjunction with the accompanying drawings and through specific implementation methods.

[0026] like Figures 1 to 3As shown, the present embodiment provides a snowplow 100. The snowplow 100 includes a motor 110, a snowplow assembly 120, a housing 130 and a handle device 140. The handle device 140 is used for a user to operate to push the snowplow 100 to walk. The handle device 140 is rotatably connected to the housing 130. The snowplow assembly 120 includes a snowplow paddle 121 and a snow throwing paddle (not shown). The housing 130 accommodates or fixes the motor 110, and accommodates at least part of the snowplow paddle 121 and the snow throwing paddle. The snowplow assembly 120 is a functional component of the snowplow 100. The motor 110 drives the snowplow paddle 121 to rotate around the first axis 101 to achieve a snowplow function. After the snowplow paddle 121 sweeps the accumulated snow into the housing 130, the snow throwing paddle rotates and throws the accumulated snow to a distance by centrifugal force.

[0027] The motor 110 may be an electric motor powered by electricity. Specifically, the motor 110 is an electric motor. The battery pack is electrically connected to the motor 110 to provide power to the motor 110. The battery pack is detachably connected to the snowplow 100. The snowplow 100 includes a running wheel 150. The running wheel 150 rotates relative to the housing 130 to enable the snowplow 100 to walk on the ground. The axis of rotation of the running wheel 150 is substantially parallel to the first axis 101. As another embodiment, tracks may be used instead of the running wheels 150 to enable the snowplow 100 to walk on the ground.

[0028] The snowplow 100 includes a snow throwing device 160. The snow throwing device 160 is used to change the movement trajectory of snow and guide the snow to a distance, or in other words, the snow throwing device 160 is used to guide the snow throwing direction of the snowplow 100. The snow throwing device 160 is arranged on the housing 130. The housing 130, the snowplow assembly 120, the snow throwing device 160 and the motor 110 constitute the main body of the snowplow 100. The housing 130 includes a snowplow bucket 131. The snowplow bucket 131 includes a side portion 132. The side portion 132 is located on both sides of the snowplow bucket 131. In this embodiment, the side portion 132 includes two side walls 133 of the snowplow bucket 131. The snowplow bucket 131 is used to accommodate a snowplow paddle 121. The snowplow paddle 121 is mounted to the side portion 132 to rotate in the snowplow bucket 131. The snowplow bucket 131 is formed with a accommodating space 135. The accommodation space 135 includes a snow inlet for snow to enter and a snow outlet for snow to be discharged from the accommodation space 135. Snow enters the accommodation space 135 from the snow inlet, and enters the snow throwing device 160 from the snow outlet to be thrown to a distance.

[0029] The handle device 140 is used for operation by the user. The handle device 140 includes a connecting rod 141 rotatably connected to the housing 130 and a gripping portion 142 for the user to hold. The handle device 140 rotates relative to the housing 130. The rotation axis of the handle device 140 is parallel to the first axis 101. The handle device 140 is in a position relative to the housing 130 as shown in FIG. Figure 2When the snowplow 100 is in the position shown in FIG. 1 , the snowplow 100 is in the snowplow state and performs snowplow operation. Figure 3 In the position shown, the snowplow 100 is in a folded state, and the user can conveniently carry or store the snowplow 100.

[0030] The connecting rod 141 includes a first connecting rod 143 and a second connecting rod 144. The first connecting rod 143 and the second connecting rod 144 are respectively connected to the two ends of the gripping portion 142. Specifically, the first connecting rod 143 and the second connecting rod 144 are hollow tubular structures and are made of metal, composite metal or plastic. The handle device 140 is symmetrical about the center plane x1. The center plane x1 intersects with the snow throwing device 160. As another embodiment, the whole formed by the first connecting rod 143, the second connecting rod 144 and the gripping portion 142 can also be regarded as a part.

[0031] like Figures 2 to 5 As shown, the snow thrower 100 includes an adjustment device 200. The user adjusts the snow throwing angle of at least part of the snow throwing device 160 through the adjustment device 200. At least part of the adjustment device 200 can rotate around the second axis 102 and the fourth axis 104. At least part of the snow throwing device 160 can rotate around the third axis 103 and the fifth axis 105. The snow throwing device 160 includes a snow throwing cap 161 and a snow throwing cylinder 162. The snow throwing cap 161 is rotatably connected to the snow throwing cylinder 162. The snow throwing cylinder 162 is rotatably connected to the housing 130. The snow throwing cap 161 can rotate around the third axis 103, and the snow throwing cylinder 162 can rotate around the fifth axis 105. When the snow throwing cylinder 162 rotates around the fifth axis 105, the snow throwing cap 161 rotates with the snow throwing cylinder 162 around the fifth axis 105. At least part of the adjustment device 200 rotates around the second axis 102 to adjust the angle at which at least part of the snow throwing device 160 rotates around the third axis 103. At least part of the adjusting device 200 rotates around the fourth axis 104 to adjust the angle of rotation of at least part of the snow throwing device 160 around the fifth axis 105. At least part of the adjusting device 200 rotates around the second axis 102 to adjust the angle of the snow throwing cap 161 rotating up and down around the third axis 103. At least part of the adjusting device 200 rotates around the fourth axis 104 to adjust the angle of the snow throwing tube 162 rotating left and right around the fifth axis 105. The adjusting device 200 can adjust the angle of the snow throwing device 160 rotating up and down and left and right, so that the user can throw the snow to a farther position, and can also flexibly adjust the throwing angle of the snow to make the snow fall to a more accurate position.

[0032] The adjustment device 200 is connected to the handle device 140. In the extension direction of the first axis 101, at least part of the adjustment device 200 is arranged on the side of the handle device 140 away from the snow throwing device 160. At least part of the adjustment device 200 is concentrated on one side of the handle device 140, which is convenient for users to operate. In the extension direction of the first axis 101, at least part of the adjustment device 200 is arranged on the side of the handle device 140 away from the snow throwing device 160. Therefore, when the handle device 140 is folded, the adjustment device 200 is always away from the snow throwing device 160, and the adjustment device 200 will not interfere with the snow throwing device 160. After the handle device 140 is folded, the length of the snow blower 100 will not be lengthened due to the position of the adjustment device 200, and the structure is compact, which is convenient for users to store the snow blower 100.

[0033] In the extension direction of the first axis 101, the fourth axis 104 is disposed on the side of the connecting rod 141 away from the snow throwing device 160. In this way, the fourth axis 104 is on the side of the connecting rod 141 away from the snow throwing device 160, and at least one of the rotation axes of the adjustment device 200 is on the side of the connecting rod 141 away from the snow throwing device 160. When the handle device 140 is folded, the adjustment device 200 will not interfere with the snow throwing device 160. In some embodiments, at least a portion of the adjustment device 200 rotates around the fourth axis 104 to adjust the angle of the snow throwing tube 162 rotating up and down around the third axis 103. The specific direction of the snow throwing device 160 when at least a portion of the adjustment device 200 rotates around the fourth axis 104 is not limited here.

[0034] In the extension direction of the first axis 101, the fourth axis 104 is disposed on the side of the grip 142 away from the snow throwing device 160. In this way, the fourth axis 104 is on the side of the grip 142 away from the snow throwing device 160, and at least one of the rotation axes of the adjustment device 200 is on the side of the grip 142 away from the snow throwing device 160. When the handle device 140 is folded, the adjustment device 200 will not interfere with the snow throwing device 160. In some embodiments, at least a portion of the adjustment device 200 rotates around the fourth axis 104 to adjust the angle of the snow throwing tube 162 rotating up and down around the third axis 103. The specific direction of the snow throwing device 160 when at least a portion of the adjustment device 200 rotates around the fourth axis 104 is not limited.

[0035] The adjustment device 200 includes an operation part 210 for user operation. The operation part 210 is configured to rotate around the second axis 102 and the fourth axis 104. The user operates the operation part 210 to rotate around the second axis 102 to adjust the angle of the snow throwing cap 161 rotating up and down around the third axis 103. The user operates the operation part 210 to rotate around the fourth axis 104 to adjust the angle of the snow throwing tube 162 rotating left and right around the fifth axis 105. The surface of the operation part 210 has an arc. In this embodiment, the operation part 210 is spherical. The user can comfortably grasp the operation part 210 to adjust the snow throwing angle of the snow throwing device 160.

[0036] In the extension direction of the first axis 101, the operating part 210 is arranged on the side of the side portion 132 close to the snow throwing device 160. The operating part 210 is arranged on the inner side of the snow sweeping bucket 131, so that after the handle device is folded, the width of the snow sweeping bucket 131 will not be widened due to the position of the adjustment device 200, and the snow sweeper 100 has a compact structure, which is convenient for packaging, transportation and storage. In the extension direction of the first axis 101, at least part of the operating part 210 is arranged on the side of the handle device 140 away from the snow throwing device 160, and is arranged on the side of the side portion 132 close to the snow throwing device 160. In the extension direction of the first axis 101, at least part of the operating part 210 is arranged between the handle device 140 and the side portion 132. After the handle device 140 is folded, the snow sweeper 100 has a compact structure, saves materials and costs for packaging and transportation, and has a beautiful appearance.

[0037] like Figure 6 to Figure 7 As shown, the side portion 132 has a front edge 134. At least a portion of the front edge 134 extends obliquely upward and backward. When the handle device 140 is folded, the front edge 134 obliquely extends upward and backward to avoid the adjustment device 200, and the adjustment device 200 does not interfere with the side portion 132. The adjustment device 200 can be moved toward the rear in the front-to-back direction, and the structure is compact, saving space, and the length of the snowplow 100 in the front-to-back direction is shortened. Figure 3 and Figure 7 As shown, in the folded state, the ratio of the length L1 of the snowplow 100 in the front-to-back direction to the width L2 of the snowplow 100 in the left-to-right direction is greater than or equal to 1.5 and less than or equal to 1.8. In some embodiments, the ratio of the length L1 of the snowplow 100 in the front-to-back direction to the width L2 of the snowplow 100 in the left-to-right direction is greater than or equal to 1.6 and less than or equal to 1.7. In some embodiments, the ratio of the length L1 of the snowplow 100 in the front-to-back direction to the width L2 of the snowplow 100 in the left-to-right direction is greater than or equal to 1.6 and less than or equal to 1.65.

[0038] like Figure 8 and Fig. 9As shown, in this embodiment, at least part of the adjustment device 200 is arranged on the right side of the handle device 140. In this way, a user who is accustomed to using his right hand can easily and conveniently adjust the snow throwing angle of the snow throwing device 160 with one hand. In some embodiments, at least part of the adjustment device 200 is arranged on the left side of the handle device 140. In this way, a user who is accustomed to using his left hand can easily and conveniently adjust the snow throwing angle of the snow throwing device 160 with one hand. The adjustment device 200 is installed on the handle device 140 as a mounting module as a whole through fasteners, such as screws, etc., which is simple to install and low in cost. In this embodiment, the adjustment device 200 is installed on the first connecting rod 143. The adjustment device 200 includes a fixing portion 220. The fixing portion 220 is sleeved on the first connecting rod 143. The fixing portion 220 includes a first protrusion 221 and a second protrusion 222. The first protrusion 221 and the second protrusion 222 respectively include holes for fasteners to pass through. The first protrusion 221 and the second protrusion 222 sandwich the first connecting rod 143 between them. The fastener passes through the first protrusion 221, the first connecting rod 143 and the second protrusion 222 in sequence to fix the adjustment device 200 to the first connecting rod 143. In some embodiments, the adjustment device 200 can also be installed on the second connecting rod 144.

[0039] like Figures 4 to 5 , Figure 10 to Figure 11 As shown, the second axis 102 is perpendicular to the fourth axis 104. The two rotation directions of the operating portion 210 are perpendicular to each other, which is ergonomic, and the user feels better when operating the operating portion 210. The adjustment device 200 includes an adjustment rod 230, and the adjustment rod 230 extends substantially along the fourth axis 104. The adjustment rod 230 includes a first connecting section 231 and a second connecting section 232. The first connecting section 231 is shorter than the second connecting section 232. The first connecting section 231 extends substantially along the sixth straight line 106, and the second connecting section 232 extends substantially along the fourth axis 104. The angle formed between the sixth straight line 106 and the fourth axis 104 is greater than or equal to 100 degrees and less than or equal to 140 degrees, so that the user can save effort and feel comfortable when operating the operating portion 210, which is ergonomic. In some embodiments, the angle formed between the sixth straight line 106 and the fourth axis 104 is greater than or equal to 115 degrees and less than or equal to 125 degrees. The adjustment device 200 includes a bushing 233 and an outer rod 234. The bushing 233 is sleeved on the adjusting rod 230, and the outer rod 234 is sleeved on the bushing 233. The adjusting rod 230 rotates relative to the bushing 233 and the outer rod 234. The bushing 233 and the outer rod 234 prevent dust from entering the adjusting rod 230. In this embodiment, the bushing 233 is made of plastic.

[0040] The operating portion 210 includes an operating end 211 and a mounting end 212. The mounting end 212 is mounted to the first connecting section 231 of the adjusting rod 230. In this embodiment, the mounting end 212 is sleeved on the first connecting section 231. Since the first connecting section 231 and the second connecting section 232 form an angle, the operating portion 210 can drive the adjusting rod 230 to rotate around the second axis 102 and the fourth axis 104 along with the operating portion 210 through the first connecting section 231. When at least part of the adjusting device 200 rotates around the second axis 102, the fourth axis 104 changes position along with at least part of the adjusting device 200. When the operating portion 210 rotates around the second axis 102, the adjusting rod 230 changes position along with the operating portion 210. The adjusting rod 230 is substantially cylindrical. When the operating portion 210 rotates around the fourth axis 104, the adjusting rod 230 rotates with the fourth axis 104 as the rotation axis. The adjusting rod 230 rotates around the fourth axis 104, saving space, and the adjusting device 200 has a compact structure.

[0041] The adjusting device 200 includes a pivot structure 240. At least part of the adjusting device 200 rotates through the pivot structure 240. In the present embodiment, the pivot structure 240 is a universal joint. In some embodiments, the pivot structure 240 may also include other structures for allowing at least part of the adjusting device 200 to rotate around at least two axes. The pivot structure 240 includes a first pivot member 241, a second pivot member 242 and a hinge 244. The first pivot member 241 and the second pivot member 242 are hingedly connected by the hinge 244 so that at least part of the adjusting device 200 can rotate at least around the second axis 102 and the fourth axis 104. The adjusting device 200 includes a baffle 246. The baffle 246 includes a bar-shaped hole. The hole limits at least part of the adjusting device 200 from rotating around the seventh axis 107.

[0042] The second connecting section 232 of the adjusting rod 230 is connected to the first pivoting member 241. One end of the first pivoting member 241 away from the hinge 244 is sleeved on the second connecting section 232. The fastener passes through one end of the first pivoting member 241 away from the hinge 244 and the second connecting section 232, so that the first pivoting member 241 rotates around the fourth axis 104 with the adjusting rod 230.

[0043] The hinge 244 allows the first pivot member 241 to rotate relative to the second pivot member 242 about the second axis 102. The hinge 244 also prevents the first pivot member 241 from rotating relative to the second pivot member 242 about the fourth axis 104, and allows the second pivot member 242 to rotate with the first pivot member 241 about the fourth axis 104. When at least a portion of the adjustment device 200 rotates about the second axis 102, the adjustment lever 230 and the first pivot member 241 rotate synchronously with the adjustment device 200 about the second axis 102. When the adjustment device 200 rotates about the fourth axis 104, the adjustment lever 230, the first pivot member 241, and the second pivot member 242 rotate synchronously with the adjustment device 200 about the fourth axis 104.

[0044] The pivot structure 240 includes a third pivot member 243. The third pivot member 243 extends substantially along the fourth axis 104. The second pivot member 242 and the third pivot member 243 are in transmission connection. One end of the second pivot member 242 away from the hinge 244 is sleeved on the third pivot member 243. The fastener passes through the second pivot member 242 and the third pivot member 243, so that the third pivot member 243 rotates as the second pivot member 242 rotates around the fourth axis 104.

[0045] The adjusting device 200 includes a transmission wheel 250. The transmission wheel 250 is substantially circular.
