[0044] Reference is made to Figures 1-6 As shown, the leaf suction machine 100 according to the embodiment of the present application comprises a leaf suction pipe 1 and a fan assembly 2.

[0045] A leaf suction passage 11 is defined in the leaf suction pipe 1, the leaf suction passage 11 is provided with a leaf suction port 111, a leaf outlet port 112 and a flow guide port 113 between the leaf suction port 111 and the leaf outlet port 112, the leaf suction port 111 is configured to allow leaves to enter the leaf suction passage 11, and the leaf outlet port 112 is configured to allow leaves to exit the leaf suction passage 11.

[0046] The fan assembly 2 is arranged outside the leaf suction pipe 1, the fan assembly 2 comprises a duct component 21 and a fan wheel 22, the duct component 21 defines a duct 211, the duct 211 has an air inlet 2111 and an air outlet 2112, the air inlet 2111 is configured to communicate with the ambient atmosphere, and the fan wheel 22 is rotatably arranged in the duct 211 to drive air to flow from the air inlet 2111 to the air outlet 2112, optionally, the fan wheel 22 can be an axial fan wheel 22, a cross-flow fan wheel 22, a centrifugal fan wheel 22 or a counter-rotating fan wheel 22, etc. The air outlet 2112 is configured to communicate with the flow guide port 113 to inject an injection air flow into the leaf suction passage 11, the injection air flow is configured to drive sundries to be sucked into the leaf suction passage 11 through the leaf suction port 111 and flow to the leaf outlet port 112, and the flow rate of the injection air flow is greater than 40 m / s. It should be noted that the "sundries" described herein includes leaves, paper scraps or plastic bags, etc.

[0047] Specifically, the wind wheel 22 rotates at high speed to generate a high-speed airflow, which forms an ejecting airflow that enters the suction passage 11 through the flow inlet 113, and the ejecting airflow draws the air in the suction passage 11 to flow out through the flow outlet 112, so that a negative pressure is generated in the suction passage 11, and the air at the suction inlet 111 continuously flows into the suction passage 11 and flows toward the flow outlet 112, and the air at the suction inlet 111 draws the sundries (leaves, paper scraps or plastic bags, etc.) into the suction passage 11, and the sundries flow toward the flow outlet 112 under the action of the air, and finally flow out through the flow outlet 112.

[0048] According to the leaf suction machine 100 of the embodiment of the present application, the fan assembly 2 is arranged outside the suction pipe 1, and a negative pressure is generated in the suction passage 11 by the siphon effect, and then a wind volume for sucking the sundries (leaves, paper scraps or plastic bags, etc.) is generated, so that the diameter of the wind wheel 22 can be reduced, and the leaf suction machine 100 is light in weight, small in size and convenient to operate. In addition, the wind volume generated by the siphon effect is large, and the efficiency of the leaf suction machine 100 for sucking the sundries (leaves, paper scraps or plastic bags, etc.) is high.

[0049] Preferably, the diameter of the wind wheel 22 is less than or equal to 50 mm, and the rotating speed of the wind wheel 22 is greater than or equal to 30000 rpm. In this way, not only the fan assembly 2 is light in weight and small in size, but also the flow rate of the ejecting airflow generated by the fan assembly 2 can be as high as 40 m / s or more, and the efficiency of the leaf suction machine 100 for sucking leaves is high, and the effect of sucking leaves is good.

[0050] Preferably, as shown in Figure 1 , the angle between the ejecting airflow and the axial center line of the suction passage 11 is α, and α satisfies: 0° < α < 90°. That is, the angle α between the ejecting airflow and the axial center line of the suction passage 11 is greater than 0° and less than 90°, so that the ejecting effect is good, and the suction passage 11 can generate an airflow that is more than one time larger than the wind volume of the flow inlet 113, thereby achieving the purpose of high-efficiency leaf suction of a small-size product.

[0051] Further, as shown in Figures 1-6 , the nozzle 3 is arranged between the flow inlet 113 and the air outlet 2112, the nozzle 3 defines a jet passage 31 therein, the cross-sectional area of the jet passage 31 decreases from the air outlet 2112 toward the flow inlet 113, and in the direction from the air outlet 2112 toward the flow inlet 113, the jet passage 31 extends toward the direction close to the axial center line of the suction passage 11, and the angle between the extension direction of the jet passage 31 and the axial center line of the suction passage 11 is α, so that by limiting the orientation of the nozzle 3, the angle α between the ejecting airflow and the axial center line of the suction passage 11 can be ensured, and in this way, the orientation of the air duct component 21 of the fan assembly 2 can be more flexible, for example Figure 1 , Figure 5 andFigure 6 As shown in FIG. 1, the air duct component 21 is arranged in parallel with the leaf suction pipe 1. As shown in FIG. 2, the air duct component 21 is arranged in parallel with the leaf suction pipe 1. Figures 2-4 As shown in FIG. 3, the air duct component 21 is arranged in parallel with the leaf suction pipe 1.

[0052] In addition, by arranging the nozzle 3 and reducing the cross-sectional area of the jet channel 31 from the air outlet 2112 towards the flow guide 113, the speed of the jet flow entering the leaf suction channel 11 through the flow guide 113 is higher. The fan wheel 22 rotates at high speed to generate high-pressure air flow, and the high-speed air flow is ejected through the nozzle 3 to form the jet flow.

[0053] In an embodiment of the present application, as shown in FIG. 1, the flow guide 113 extends along the circumference of the leaf suction channel 11. For example, the flow guide 113 can be a closed annular structure that surrounds the leaf suction channel 11, or the flow guide 113 can be a non-closed annular structure that only surrounds a part of the circumference of the leaf suction channel 11. Figures 1-6

[0054] In an embodiment of the present application, the fan assembly 2 is detachably connected to the leaf suction pipe 1, for example, by a threaded fastener or a buckle structure.

When the leaf storage base 51 or the cover 52 is provided with an air outlet, air entering the leaf storage cavity can be discharged from the leaf storage cavity through the air outlet; when the leaf storage base 51 or the cover 52 is a vent, air entering the leaf storage cavity can be discharged from the leaf storage cavity through the vent holes on the vent. It should be noted that the vent is made of a breathable material, such as nylon cloth, linen, cotton cloth, etc.

[0060] Optionally, such as Figure 2 As shown, the leaf storage device 5 can be a breathable garbage bag, which is low in cost.

[0061] Optionally, the leaf storage device 5 may also be equipped with a shoulder strap, which can be carried on the shoulder or back to reduce the burden on the operator's arms.

[0062] In one embodiment of the present invention, a transmission pipe 6 extending in a straight line or curve is provided between the leaf storage device 5 and the leaf outlet 112. The leaf storage device 5 and the leaf outlet 112 are connected by the transmission pipe 6, thereby facilitating the connection between the leaf storage device 5 and the leaf outlet 112 and allowing for more flexible positioning of the leaf storage device 5 and the suction pipe 1. The shape of the transmission pipe 6 can be set as needed, for example in... Figures 2-3 as well as Figures 5-6 As shown, transmission pipe 6 extends in a curved (arc) shape; in Figure 4 In the example shown, the transmission pipe 6 extends in a straight line.

[0064] The following is for reference. Figures 1-7A blower-suction machine according to an embodiment of the second aspect of the present application is described.

[0065] Reference is made to Figures 1-7 As shown, the blower-suction machine according to an embodiment of the present application comprises a suction-leaf pipe 1 and a fan assembly 2.

[0066] The suction-leaf pipe 1 defines a suction-leaf channel 11 therein, the suction-leaf channel 11 is provided with a suction-leaf opening 111, an ejection-leaf opening 112 and a flow guide opening 113 between the suction-leaf opening 111 and the ejection-leaf opening 112, leaves enter the suction-leaf channel 11 through the suction-leaf opening 111 and are ejected from the suction-leaf channel 11 through the ejection-leaf opening 112.

[0067] The fan assembly 2 is arranged outside the suction-leaf pipe 1, the fan assembly 2 comprises a wind tunnel component 21 and a fan wheel 22, the wind tunnel component 21 defines a wind tunnel 211, the wind tunnel 211 has an air inlet 2111 and an air outlet 2112, the air inlet 2111 is communicated with the outside atmosphere, the fan wheel 22 is rotatably arranged in the wind tunnel 211 to drive air to flow from the air inlet 2111 to the air outlet 2112, optionally, the fan wheel 22 can be an axial fan wheel 22, a cross-flow fan wheel 22, a centrifugal fan wheel 22 or a counter-rotating fan wheel 22, etc.

[0068] The fan assembly 2 has a separated state (as shown in Figure 7 ) separated from the suction-leaf pipe 1 and a connected state (as shown in Figures 1-6 ) connected with the suction-leaf pipe 1, the fan assembly 2 is switchable between the separated state (as shown in Figure 7 ) and the connected state (as shown in Figures 1-6 ).

[0070] When the fan assembly 2 is in the connected state, as shown in Figures 1-6 , the air outlet 2112 is communicated with the flow guide opening 113 to inject an ejecting air flow into the suction-leaf channel 11, the ejecting air flow is used to drive sundries to be sucked into the suction-leaf channel 11 through the suction-leaf opening 111 and flow to the ejection-leaf opening 112, the flow rate of the ejecting air flow is greater than 40 m / s. It should be noted that the "sundries" mentioned herein includes leaves, paper scraps or plastic bags, etc. At this time, the fan assembly and the suction-leaf pipe jointly constitute a suction-leaf machine.

[0071] The blowing and sucking machine according to the embodiment of the present application can be used as a blower and a leaf sucking machine by switching the fan assembly 2 between the separated state and the connected state, and is flexible in use and good in versatility. When the blowing and sucking machine is used as a leaf sucking machine, the fan assembly 2 is arranged outside the leaf sucking pipe 1, and a negative pressure is generated in the leaf sucking channel 11 by siphon effect, and then a wind volume for sucking sundries (leaves, paper scraps or plastic bags, etc.) is generated, so that the diameter of the fan wheel 22 can be reduced, and the blowing and sucking machine is light in weight, small in size and convenient to operate. In addition, the wind volume generated by siphon effect is large, and the blowing and sucking machine is high in efficiency for sucking sundries (leaves, paper scraps or plastic bags, etc.).

[0072] Preferably, the diameter of the fan wheel 22 is less than or equal to 50 mm, and the rotating speed of the fan wheel 22 is greater than or equal to 30000 rpm.

[0073] Preferably, as shown in Figure 1 , the included angle between the ejecting air flow and the axial center line of the leaf sucking channel 11 is α, and α satisfies: 0°<α<90°. That is, the included angle α between the ejecting air flow and the axial center line of the leaf sucking channel 11 is greater than 0° and less than 90°, so that the ejecting effect is good, and the leaf sucking channel 11 can generate an air flow which is more than one time of the wind volume of the flow port 113, thereby realizing the purpose of high efficiency for sucking leaves by a small size product.

[0074] Further, as shown in Figures 1-6 , the nozzle 3 is arranged between the flow port 113 and the air outlet 2112, the nozzle 3 defines the injection channel 31 therein, the cross-sectional area of the injection channel 31 decreases from the air outlet 2112 towards the flow port 113, and in the direction from the air outlet 2112 towards the flow port 113, the injection channel 31 extends towards the direction close to the axial center line of the leaf sucking channel 11, and the included angle between the extending direction of the injection channel 31 and the axial center line of the leaf sucking channel 11 is α, so that by limiting the orientation of the nozzle 3, the included angle between the ejecting air flow and the axial center line of the leaf sucking channel 11 can be ensured to be α, and in this way, the orientation of the air duct component 21 of the fan assembly 2 can be more flexible, for example, as shown in Figure 1 , Figure 5 and Figure 6 , the air duct component 21 is arranged in parallel with the leaf sucking pipe 1, and as shown in Figures 2-4 , the air duct component 21 is arranged obliquely to the leaf sucking pipe 1.

[0075] Further, by arranging the nozzle 3 and reducing the cross-sectional area of the jet channel 31 from the air outlet 2112 towards the flow guide 113, the velocity of the jet air flow entering the suction channel 11 from the flow guide 113 is higher. The high-speed rotation of the fan wheel 22 generates a high-pressure air flow, and the high-speed air flow is ejected from the nozzle 3 to form the jet air flow.

[0076] In one embodiment of the present application, as shown in Figures 1-6 Fig. 1, the flow guide 113 extends along the circumference of the suction channel 11. For example, the flow guide 113 can be a closed annular structure surrounding the circumference of the suction channel 11, or the flow guide 113 can be a non-closed annular structure surrounding only a portion of the circumference of the suction channel 11.

[0077] In one embodiment of the present application, the fan assembly 2 is detachably connected to the suction tube 1, for example, by a threaded fastener or a snap structure. Thus, the fan assembly 2 can be switched between a detached state and a connected state.

By arranging the cover 52, the leaves in the leaf storage cavity can be prevented from being blown out of the leaf storage device 5 through the open mouth. Further, at least one of the leaf storage base 51 and the cover 52 is provided with an air outlet, or at least one of the leaf storage base 51 and the cover 52 is a gas-permeable member. When the leaf storage base 51 or the cover 52 is provided with the air outlet, the air in the leaf storage cavity can be discharged out of the leaf storage cavity through the air outlet; when the leaf storage base 51 or the cover 52 is the gas-permeable member, the air in the leaf storage cavity can be discharged out of the leaf storage cavity through the gas-permeable holes of the gas-permeable member.

[0081] Optionally, asFigure 2 The storage device 5 can be a ventilated garbage bag, which is low in cost.

[0082] Optionally, the storage device 5 can be provided with a shoulder strap, so that the storage device 5 can be carried on the shoulder or back, thereby reducing the burden on the operator's arms.

[0083] In an embodiment of the present application, a transmission pipe 6 extending in a straight line or a curve is arranged between the storage device 5 and the leaf outlet 112.
