Description

Technical Field

[0001] This application relates to the field of garden tool technology, and in particular to a leaf blower / vacuumer. Background Technology

[0002] Leaf blowers are garden tools used for outdoor leaf removal. They have both blowing and suction functions. Typically, a leaf blower has a volute inside its casing, containing an impeller driven by a motor. The casing has a blower port and a suction port connected to the volute. When the motor drives the impeller to rotate inside the volute, air is drawn in through the suction port and blown out through the blower port. In commercially available leaf blowers, a collection bag is installed at the blower port and a suction pipe at the suction port. When the blower operates for extended periods, the collection bag accumulates a significant amount of leaf debris. When the leaves contain moisture, this increases the weight of the collection bag, and small pebbles are also sucked into it, further increasing its weight. This makes the collection bag prone to detaching from the blower port, increasing the overall weight of the leaf blower and reducing the worker's workload and decreasing the efficiency of leaf removal. Utility Model Content

[0003] The purpose of this utility model is to provide a leaf blowing and suction machine in view of the defects and deficiencies of the existing technology.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] The device includes a housing and an air duct. One side of the housing has an air intake, and the other side of the housing has an air outlet. One end of the air duct is installed on the air intake. The device also includes a connecting pipe and a collection backpack. One end of the connecting pipe is located outside the air outlet, and the other end of the connecting pipe is connected to the inside of the collection backpack.

[0006] Preferably, the collection backpack contains a moisture-proof layer, and one end of the connecting tube is connected to the interior of the moisture-proof layer.

[0007] Preferably, a blowpipe is installed at the outer end of the air outlet, and the connecting pipe is sleeved on the outer end of the blowpipe.

[0008] Preferably, a plurality of fixing blocks are evenly arranged circumferentially on the outer periphery of the blowpipe, and a plurality of locking grooves are evenly opened on the side wall of one end of the connecting pipe, and the fixing blocks are slidably fixed in the locking grooves.

[0009] Preferably, a sealing ring is provided between the blowpipe and the connecting pipe.

[0010] Preferably, a buffer partition is provided on one side of the collection backpack, and the outer side of the buffer partition is wavy.

[0011] Preferably, the side wall of the collection backpack is provided with a power supply box.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] 1. When it is necessary to clean up the fallen leaves on the ground, first put the collection backpack on the back of the worker, then lift the machine casing so that the outer end of the air duct is aligned with the ground with fallen leaves, then start the fan inside the machine casing to suck the fallen leaves into the air duct, and then through the machine casing and connecting pipe into the collection backpack. Since the collection backpack is carried on the back, the weight of the collection backpack will not act on the connecting pipe, and the connecting pipe will not detach from the air outlet, which improves the convenience of using the leaf blowing and suction machine.

[0014] 2. The collection backpack has a moisture-proof layer inside. When there is moisture mixed in with the dead leaves, it can prevent the moisture from seeping out from the moisture-proof layer, so that the collection backpack will not be affected by moisture and will not get damp, thus improving the stability of the collection backpack.

[0015] 3. A blowpipe is installed outside the air outlet. One end of the connecting pipe is fitted onto the outer end of the blowpipe. Then, the fixing blocks around the blowpipe are inserted and fixed into the locking groove at one end of the connecting pipe, which improves the convenience of installing the connecting pipe. When the leaf blower needs to blow dry leaves, the connecting pipe can be removed from the blowpipe. Then, the fan can be started to blow the dry leaves, which improves the convenience of switching between blowing and suction. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] This application discloses a leaf blowing and suction machine.

[0023] Reference Figure 1 and Figure 2 The system includes a housing 1, an air duct 2, a connecting pipe 3, and a collection backpack 4. The housing 1 has an air intake 5 on one side and an air outlet 6 on the other. One end of the air duct 2 is fixed to the outer end of the air intake 5. A blower 7 is snapped onto the outer end of the air outlet 6 of the housing 1. One end of the connecting pipe 3 is fitted around the outer edge of the blower 7, and the other end of the connecting pipe 3 is inserted into the collection backpack 4. First, the collection backpack 4 is carried on the back of the worker. Then, the housing 1 is lifted, aligning the outer end of the air duct 2 with the ground covered in dead leaves. The fan inside the housing 1 is then activated, drawing the dead leaves into the air duct 2, which then passes through the housing 1 and the connecting pipe 3 into the collection backpack 4.

[0024] The inside of the collection backpack 4 is equipped with a moisture-proof layer 8, which is attached to the inner wall of the collection backpack 4. One end of the connecting tube 3 is inserted into the collection backpack 4 and connected to the moisture-proof layer 8. When there is moisture mixed in with the dead leaves, the moisture-proof layer 8 can prevent moisture from seeping out, so that the collection backpack 4 will not be affected by moisture and become damp.

[0025] A power supply box 13 is fixedly installed on the side wall of the backpack 4. The power supply box 13 contains a battery. The plug on the outside of the housing 1 is connected to the battery in the power supply box 13, which allows the fan inside the housing 1 to work.

[0026] A cushioning partition 9 is fixedly connected to one side of the collection backpack 4, and the outer side of the cushioning partition 9 is wavy. The cushioning partition 9 can improve the comfort of the staff carrying the collection backpack 4, and the outer side of the cushioning partition 9 can conform to the staff's back.

[0027] Reference Figure 3 and Figure 4 Three fixing blocks 10 are uniformly and integrally arranged on the circumference of the outer end of the blowpipe 7. Three locking grooves 11 are uniformly opened on one end of the connecting pipe 3. The locking grooves 11 are "L" shaped. The three fixing blocks 10 slide into the openings of the three locking grooves 11 respectively. Then, the connecting pipe 3 is rotated to lock the fixing blocks 10 into the bottom of the locking grooves 11. The blowpipe 7 is installed outside the air outlet 6. One end of the connecting pipe 3 is fitted onto the outer end of the blowpipe 7. Then, the fixing blocks 10 on the circumference of the blowpipe 7 are inserted and fixed into the locking grooves 11 at one end of the connecting pipe 3. This improves the convenience of installing the connecting pipe 3. When it is necessary to use the leaf blower to blow dry leaves, the connecting pipe 3 can be removed from the blowpipe 7, and then the fan can be started to blow the dry leaves.

[0028] A sealing ring 12 is placed at the outer end of the blowpipe 7, and one end of the sealing ring 12 abuts against the inner wall of the connecting pipe 3. When the fixing block 10 slides and locks in the locking groove 11, the sealing ring 12 can be squeezed, thereby improving the sealing between the blowpipe 7 and the connecting pipe 3.

[0029] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
