Description

Technical Field

[0001] This utility model relates to the field of garden tool technology, and more specifically, to a leaf blowing and suction integrated machine. Background Technology

[0002] A leaf blower is a garden tool used to blow away leaves. Currently, leaf blowers on the market only have the function of blowing away leaves, which is a drawback of limited functionality. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a leaf blowing and suction integrated machine, which can not only blow and sweep leaves, but also collect leaves, and has the advantages of multiple functions.

[0004] This utility model provides a leaf blowing and suction integrated machine, including a housing assembly, a fan assembly, and a blowing and suction pipe. The fan assembly is fixed inside the housing assembly, and the blowing and suction pipe is connected to the front end of the housing assembly. The housing assembly has an air inlet channel and an air outlet channel. The air inlet end of the fan assembly is connected to the air inlet channel, and the air outlet end of the fan assembly is connected to the air outlet channel. The leaf blowing and suction integrated machine also includes a guide component. The guide component is rotatably connected inside the housing assembly and has a rotating handle that extends outside the housing assembly. The side wall of the housing assembly has an air inlet and a leaf outlet, and the leaf outlet is detachably connected to a collection bag. When the guide component rotates relative to the housing assembly to a first position, the blowing and suction pipe is connected to the air inlet channel through the guide component, and the leaf outlet is connected to the air outlet channel through the guide component. When the guide component rotates relative to the housing assembly to a second position, the air inlet is connected to the air inlet channel through the guide component, and the blowing and suction pipe is connected to the air outlet channel through the guide component.

[0005] By adopting the above-described structure, this invention can not only sweep leaves but also collect them, thus possessing multiple advantages.

[0006] In one possible implementation, the guide member is provided with a first guide cavity and a second guide cavity distributed vertically. When the guide member rotates relative to the housing assembly to a first position, the blow-suction pipe communicates with the air inlet channel through the second guide cavity, and the blade outlet communicates with the air outlet channel through the first guide cavity. When the guide member rotates relative to the housing assembly to a second position, the air inlet communicates with the air inlet channel through the second guide cavity, and the blow-suction pipe communicates with the air outlet channel through the first guide cavity. With this structure, when the guide member rotates relative to the housing assembly to the first position, the blow-suction pipe can reliably communicate with the air inlet channel through the second guide cavity, and the blade outlet can reliably communicate with the air outlet channel through the first guide cavity. When the guide member rotates relative to the housing assembly to the second position, the air inlet can reliably communicate with the air inlet channel through the second guide cavity, and the blow-suction pipe can reliably communicate with the air outlet channel through the first guide cavity.

[0007] In one possible implementation, an annular rib is provided on the outer wall of the middle part of the flow guide, and an annular groove adapted to the annular rib is provided on the inner wall of the housing assembly. The annular rib is rotatably embedded in the annular groove. With this structure, the flow guide can be reliably rotatably connected to the inside of the housing assembly under the cooperation of the annular rib and the annular groove.

[0008] In one possible implementation, the top of the housing assembly has a through hole for the rotating handle to extend out of the housing assembly, and the bottom of the rotating handle has a limiting rib. Two circumferentially evenly distributed arc-shaped grooves are provided on the sidewall of the through hole, and the two ends of the limiting rib are slidably connected to one of the arc-shaped grooves. When the guide member rotates relative to the housing assembly to a first position, the two ends of the limiting rib abut against one end of the corresponding arc-shaped groove. When the guide member rotates relative to the housing assembly to a second position, the two ends of the limiting rib abut against the other end of the corresponding arc-shaped groove. With this structure, when the guide member rotates relative to the housing assembly to the first position, the two ends of the limiting rib can abut against one end of the corresponding arc-shaped groove; when the guide member rotates relative to the housing assembly to the second position, the two ends of the limiting rib can abut against the other end of the corresponding arc-shaped groove. This achieves rotational limiting of the guide member and ensures that the guide member can only switch between the first and second positions.

[0009] In one possible implementation, a connecting sleeve is fixed at the opening of the collection bag, the connecting sleeve is fitted onto the outside of the leaf outlet and rotated to engage with the leaf outlet; with this structure, the collection bag can be easily rotated to engage with the leaf outlet via the connecting sleeve, or can be detached from the leaf outlet.

[0010] In one possible implementation, the inner wall of the connecting sleeve is provided with a plurality of circumferentially evenly distributed locking blocks, and the leaf outlet is provided with an opening groove corresponding to each locking block. Each opening groove has a locking slot on one side of its inner end. When the connecting sleeve is fitted onto the leaf outlet, each locking block is inserted into the corresponding opening groove, and after the connecting sleeve rotates relative to the leaf outlet, each locking block engages with the corresponding locking slot. With this structure, when the connecting sleeve is fitted onto the leaf outlet, each locking block can be inserted into the corresponding opening groove, and after the connecting sleeve rotates relative to the leaf outlet, each locking block can engage with the corresponding locking slot, thus allowing the connecting sleeve to easily rotate and engage with the leaf outlet. Furthermore, after the connecting sleeve rotates in the opposite direction, each locking block can disengage from the corresponding locking slot, and when the connecting sleeve is pulled away from the leaf outlet, the locking block can disengage from the opening groove, meaning the connecting sleeve can detach from the leaf outlet, thus achieving the separation of the collection bag from the leaf outlet.

[0011] In one possible implementation, a sealing ring is embedded in the outer wall of the leaf outlet. When the connecting sleeve is fitted onto the outside of the leaf outlet, the sealing ring is used to seal the gap between the connecting sleeve and the leaf outlet. With this structure, during the process of air and leaves entering the collection bag together, the sealing ring can prevent air leakage between the leaf outlet and the connecting sleeve, thereby ensuring that the leaves enter the collection bag along with the air, which enables the collection bag to reliably collect the leaves.

[0012] In one possible implementation, a plurality of circumferentially spaced limiting blocks are provided on the inner wall of the connecting sleeve. When the connecting sleeve is fitted onto the outside of the leaf outlet, the limiting blocks abut against the outer end of the leaf outlet. With this structure, after the connecting sleeve is fitted onto the outside of the leaf outlet, the limiting blocks can abut against the outer end of the leaf outlet, thereby achieving axial limiting of the connecting sleeve and the leaf outlet. In addition, with the limiting blocks abutting against the outer end of the leaf outlet, and after the connecting sleeve and the leaf outlet are rotated and fastened, axial limiting of the connecting sleeve and the leaf outlet can be achieved, thus improving the reliability of the rotational fastening of the connecting sleeve and the leaf outlet.

[0024] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0025] See Figure 1-8As shown in the embodiment of this application, a leaf blowing and suction integrated machine is disclosed, including a housing assembly 1, a fan assembly 2, and a blowing and suction pipe 3; the fan assembly 2 is fixed inside the housing assembly 1, and the blowing and suction pipe 3 is connected to the front end of the housing assembly 1. The housing assembly 1 is provided with an air inlet channel 11 and an air outlet channel 12. The air inlet end of the fan assembly 2 is connected to the air inlet channel 11, and the air outlet end of the fan assembly 2 is connected to the air outlet channel 12; the leaf blowing and suction integrated machine also includes a guide member 4; the guide member 4 is rotatably connected inside the housing assembly 1, and a rotating handle 41 is provided on the guide member 4, which extends out of the housing assembly 1; the side wall of the housing assembly 1 is provided with The system has an air inlet 13 and an air outlet 14, with the air outlet 14 detachably connected to a collection bag 5. When the guide member 4 rotates relative to the housing assembly 1 to the first position, the blowing and suction pipe 3 is connected to the air inlet channel 11 via the guide member 4, and the air outlet 14 is connected to the air outlet channel 12 via the guide member 4. When the guide member 4 rotates relative to the housing assembly 1 to the second position, the air inlet 13 is connected to the air inlet channel 11 via the guide member 4, and the blowing and suction pipe 3 is connected to the air outlet channel 12 via the guide member 4. The collection bag is a cloth bag, which allows leaves to be collected after entering the bag, while the air entering the bag can leak out through the pores of the cloth bag.

[0026] In use, when the guide member rotates to the first position relative to the housing assembly, the blowing and suction pipe connects to the air inlet channel via the guide member, and the leaf outlet connects to the air outlet channel via the guide member. In this state, when the fan assembly operates, it draws in air through the blowing and suction pipe and the air inlet channel. That is, leaves and air are sequentially drawn into the blowing and suction pipe and the air inlet channel. Subsequently, the leaves and air enter the collection bag through the air outlet channel and the leaf outlet, whereby the leaves are collected, and the air leaks out through the pores of the collection bag, thus achieving… The collection of leaves: When the guide component rotates to the second position relative to the housing assembly, the air inlet can be connected to the air inlet channel through the guide component, and the blow-suction pipe can be connected to the air outlet channel through the guide component. In this state, when the fan assembly is working, the fan assembly can draw in air through the air inlet and air inlet channel, and the air can be blown out through the air outlet channel and blow-suction pipe. At this time, the leaves can be swept. In addition, under the action of the air inlet, the air volume of the air inlet channel can be increased, thereby increasing the air volume blown out from the air outlet channel and blow-suction pipe, so as to improve the sweeping effect of leaves.

[0027] The guide member 4 is provided with a first guide cavity 42 and a second guide cavity 43 distributed vertically. When the guide member 4 rotates relative to the housing assembly 1 to the first position, the blowing and suction pipe 3 is connected to the air inlet channel 11 through the second guide cavity 43, and the blade outlet 14 is connected to the air outlet channel 12 through the first guide cavity 42. When the guide member 4 rotates relative to the housing assembly 1 to the second position, the air inlet 13 is connected to the air inlet channel 11 through the second guide cavity 43, and the blowing and suction pipe 3 is connected to the air outlet channel 12 through the first guide cavity 42. With this structure, when the guide member 4 rotates relative to the housing assembly 1 to the first position, the blowing and suction pipe can reliably connect to the air inlet channel through the second guide cavity, and the blade outlet can reliably connect to the air outlet channel through the first guide cavity. When the guide member rotates relative to the housing assembly to the second position, the air inlet can reliably connect to the air inlet channel through the second guide cavity, and the blowing and suction pipe can reliably connect to the air outlet channel through the first guide cavity.

[0028] An annular rib 44 is provided on the outer wall of the middle part of the flow guide 4, and an annular groove 15 adapted to the annular rib 44 is provided on the inner wall of the housing assembly 1. The annular rib 44 is rotatably embedded in the annular groove 15. With this structure, the flow guide can be reliably rotatably connected to the inside of the housing assembly under the cooperation of the annular rib and the annular groove.

[0029] The top of the housing assembly 1 is provided with a through hole 16 for the rotating handle 41 to extend out of the housing assembly 1. The bottom of the rotating handle 41 is provided with a limiting rib 411. The side wall of the through hole 16 is provided with two circumferentially evenly distributed arc-shaped grooves 161. The two ends of the limiting rib 411 are respectively slidably connected in one of the arc-shaped grooves 161. When the guide member 4 rotates relative to the housing assembly 1 to the first position, the two ends of the limiting rib 411 abut against one end of the arc-shaped groove 161 at the corresponding position. When the guide member 4 rotates relative to the housing assembly 1 to the second position, the two ends of the limiting rib 411 abut against one end of the arc-shaped groove 161 at the corresponding position. In the second position, the two ends of the limiting rib 411 abut against the other end of the arc groove 161 at the corresponding position. With this structure, when the guide member rotates to the first position relative to the housing assembly, the two ends of the limiting rib can abut against one end of the arc groove at the corresponding position. When the guide member rotates to the second position relative to the housing assembly, the two ends of the limiting rib can abut against the other end of the arc groove at the corresponding position. That is, the rotation of the guide member can be limited, and the guide member can only switch between the first position and the second position.

[0030] A connecting sleeve 6 is fixed at the opening of the collection bag 5. The connecting sleeve 6 is fitted onto the outside of the leaf outlet 14 and rotated to engage with the leaf outlet 14. With this structure, the collection bag can be easily rotated to engage with the leaf outlet through the connecting sleeve, or can be removed from the leaf outlet.

[0031] The inner wall of the connecting sleeve 6 is provided with a plurality of circumferentially evenly distributed locking blocks 61. The leaf outlet 14 is provided with opening slots 141 corresponding to the plurality of locking blocks 61 one by one. Each opening slot 141 has a locking groove 142 on one side of its inner end. When the connecting sleeve 6 is fitted onto the leaf outlet 14, each locking block 61 is inserted into the opening slot 141 at the corresponding position. After the connecting sleeve 6 rotates relative to the leaf outlet 14, each locking block 61 is engaged in the locking groove 142 at the corresponding position. By adopting this structure, the connecting sleeve... When connected to the leaf outlet, each locking block can be inserted into the corresponding slot. After the connecting sleeve rotates relative to the leaf outlet, each locking block can be engaged in the corresponding slot, allowing the connecting sleeve to be easily rotated and fastened to the leaf outlet. In addition, after the connecting sleeve rotates in the opposite direction, each locking block can disengage from the corresponding slot. When the connecting sleeve is pulled away from the leaf outlet, the locking block can disengage from the slot, meaning the connecting sleeve can be separated from the leaf outlet, thus achieving the separation of the collection bag from the leaf outlet.

[0032] A sealing ring 143 is embedded on the outer wall of the leaf outlet 14. When the connecting sleeve 6 is fitted onto the outside of the leaf outlet 14, the sealing ring 143 is used to seal the gap between the connecting sleeve 6 and the leaf outlet 14. With this structure, when air and leaves enter the collection bag together, the sealing ring can prevent air leakage between the leaf outlet and the connecting sleeve, thus ensuring that the leaves enter the collection bag together with the air, which enables the collection bag to reliably collect the leaves.

[0033] The inner wall of the connecting sleeve 6 is provided with several circumferentially spaced limiting blocks 62. When the connecting sleeve 6 is fitted onto the outside of the leaf outlet 14, the limiting blocks 62 abut against the outer end of the leaf outlet 14. With this structure, after the connecting sleeve is fitted onto the outside of the leaf outlet, the limiting blocks can abut against the outer end of the leaf outlet, thereby achieving axial limiting of the connecting sleeve and the leaf outlet. In addition, with the limiting blocks abutting against the outer end of the leaf outlet, and after the connecting sleeve and the leaf outlet are rotated and fastened, axial limiting of the connecting sleeve and the leaf outlet can be achieved, which can improve the reliability of the rotational fastening of the connecting sleeve and the leaf outlet.
