[0053] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and the description of the preferred embodiments.

[0054] A leaf-cleaning blower / vacuum unit mainly includes a housing 1, a power unit, and a piping unit. The housing 1 is hollow, forming an inner cavity. A partition 121 divides the inner cavity into an equipment compartment 11 and a waste compartment 12. The power unit is arranged inside the housing 1 via the partition 121. The power unit includes a power mechanism, each of which includes a fan 13 arranged on the partition 121. The fan 13 is located inside the equipment compartment 11. The air inlet of the fan 13 passes through the partition 121 and is connected to the waste compartment 12. The piping unit includes a suction pipe and an internal pipe 124. The internal pipe 124 is arranged in... Inside the casing 1; the suction pipe is connected to the garbage compartment 12 via an internal pipe 124; the air outlet of the fan 13 can be connected to the equipment compartment 11 or the internal pipe 124; the casing 1 is provided with an air inlet 111; the air inlet 111 is connected to the equipment compartment 11; the partition 121 is provided with a vent for connecting the equipment compartment 11 and the garbage compartment 12; the vent and the internal pipe 124 are connected by a sealing mechanism; the present invention, through the cooperation of the sealing mechanism and the control unit 17, can realize the switching of the air duct of the blower and suction machine, and realize that the air outlet pipe and the air inlet pipe share a single blower and suction pipe 3, without the need for frequent replacement of the air inlet and outlet pipes.

[0055] Meanwhile, the housing 1 of the present invention is divided into a garbage compartment 12 and an equipment compartment 11, which can prevent garbage from damaging the impeller of the fan 13 and effectively improve the service life of the fan 13.

[0056] Specifically, the housing 1 of the present invention is hollow inside, forming an inner cavity; a partition 121 is provided inside the housing 1, dividing the inner cavity into two independent spaces: mainly an equipment compartment 11 and a waste compartment 12; the housing 1 is also provided with an air inlet 111, which is connected to the equipment compartment 11; the housing 1 is the outer shell structure of the entire equipment, which plays the role of protecting the internal components and supporting the overall structure; the partition 121 is used to separate functional areas, realize dry and wet separation, prevent waste from entering the equipment compartment 11, and protect the power unit; the air inlet 111 provides an external air source for the equipment compartment 11, ensuring smooth air intake of the fan 13 and forming airflow circulation.

[0057] In this invention, the power unit is arranged inside the housing 1 via a partition 121, which facilitates the placement of the power unit.

[0058] In this invention, the power unit mainly includes a power mechanism, and each power mechanism includes a fan 13, which is arranged in the equipment compartment 11. The air inlet of the fan 13 passes through the partition 121 and is connected to the garbage compartment 12. The air outlet of the fan 13 can be connected to the equipment compartment 11 or the internal pipe 124 (with switching function).

[0059] The blower 13 is the core component of the blowing and suction function, providing negative pressure (suction) and positive pressure (blowing). When the air inlet of the blower 13 is connected to the garbage compartment 12 and the air outlet is connected to the equipment compartment 11, a suction mode is formed: negative pressure is formed in the garbage compartment 12, and fallen leaves and other debris are sucked in through the suction pipe.

[0060] When the air outlet of the fan 13 is switched to the internal duct 124, a blowing mode can be formed: the airflow is directed to the suction duct for blowing away fallen leaves.

[0061] The blower 13 is installed through the partition 121 to avoid direct contact with garbage, thereby improving its service life and safety.

[0062] In this invention, the piping unit mainly includes a suction pipe and an internal pipe 124; the internal pipe 124 is arranged inside the housing 1; it is generally connected to the bottom of the housing 1, and the connection method can be plug-in, threaded connection, etc.

[0063] In this invention, the suction pipe is connected to the garbage compartment 12 via the internal pipe 124; the suction pipe is an external working pipe used to directly contact the ground or the area to be cleaned, so as to suck in or blow out fallen leaves; the internal pipe 124 serves as a connecting channel, connecting the suction pipe to the garbage compartment 12 or the air outlet of the blower 13, so as to switch the airflow path; at the same time, it facilitates the entry of subsequent garbage.

[0064] The arrangement of the duct unit determines the airflow direction and is the key channel for switching between "blowing" and "inhaling" functions.

[0065] The sealing mechanism is mainly used to seal the vent holes and the ends of the internal pipes 124.

[0066] It is mainly used to control the connection and disconnection between the equipment compartment 11 and the waste compartment 12, as well as the switching of the airflow path of the internal pipe 124.

[0067] The leaf cleaning blower and suction machine disclosed in this invention achieves dual functions of blowing and collecting through clever partition 121, bidirectional airflow control of fan 13, and switching of sealing mechanism. It has a compact structure and high functional integration, and is suitable for leaf cleaning operations in gardens, streets, communities and other places.

[0068] Furthermore, the power unit described in this invention includes two spaced-apart power mechanisms; the arrangement of the two power mechanisms ensures the power source of the power unit and the blowing and sucking capabilities of the blow-and-suction integrated machine.

[0069] In this invention, the power unit includes two spaced-apart power mechanisms; the two power mechanisms have the same structure and both include a fan 13 arranged on a partition 121. The fan 13 is arranged symmetrically in the transverse direction along the casing 1, and its air inlet end is connected to the garbage compartment 12 through the partition 121. The air outlet end can be switched to connect to the equipment compartment 11 or the internal pipe 124.

[0070] Furthermore, in this invention, each of the blowers 13 is connected to a bridging mechanism at its outlet end; the bridging mechanism plays a good role in connection and communication, facilitating the connection between the outlet section of the blower 13 and the internal pipe 124, and facilitating subsequent blowing operations.

[0071] Specifically, the bridging mechanism described in this invention includes an external discharge pipe and a bridging pipe 101. The bridging pipe 101 generally extends from the equipment compartment 11 to the waste compartment 12. The external discharge pipe is mainly arranged inside the equipment compartment 11. The bridging pipe 101 facilitates the connection between the air outlet of the fan 13 and the internal pipe 124.

[0072] Specifically, in this invention, one end of the bridging pipe 101 is connected to the air outlet of the fan 13, and the other end is connected to the internal pipe 124; one end of the external exhaust pipe is connected to the air outlet of the fan 13, and the other end extends freely to the equipment compartment 11; based on this design, subsequent air blowing operations are facilitated.

[0073] Furthermore, in this invention, the air outlet of the fan 13 is connected to the bridging mechanism via the control unit 17; the control unit 17 is essentially a switch structure, which facilitates the connection between the bridging pipe 101 or the exhaust pipe and the air outlet of the fan 13 as needed.

[0074] Specifically, in this invention, the control unit 17 includes a control valve, which can control the connection between the bridging pipe 101 or the exhaust pipe and the air outlet of the fan 13; generally, a two-position three-way ventilation valve can be selected; to facilitate the control of the gas direction at the air outlet of the fan 13.

[0075] Furthermore, the sealing mechanism in this invention includes a plug 15, which is connected to a driving member 16. The driving member 16 can control the plug 15 to move closer to the end of the internal pipe 124 or the vent hole. The plug 15 serves two purposes: firstly, it acts as a seal, facilitating the sealing and blocking of the internal pipe 124 or the vent hole; secondly, it provides excellent shock absorption and buffering, preventing excessive kinetic energy from the garbage entering through the internal pipe 124 and thus avoiding impact noise.

[0076] In addition, in this invention, the vent is located above the internal pipe 124; the sealing mechanism is connected to the partition 121; based on this design, a sealing structure can be set up to achieve the sealing operation between the vent and the internal pipe 124.

[0077] In this invention, the internal pipe 124 is a columnar pipe structure with openings at both ends.

[0078] In this invention, the plug 15 is a rubber plug 15, and the vertical cross section of the plug 15 is an inverted trapezoid; the rubber plug 15 plays a good role in sealing and shock absorption.

[0079] The inverted trapezoidal structure here makes the plug 15 have a larger top and smaller bottom; one is to facilitate the sealing of the plug 15 at the end of the internal pipe 124, and the larger size at the end near the partition 121 facilitates the sealing of multiple vent holes.

[0080] In addition, in this invention, the internal pipe 124 mainly includes a lower pipe 1241 and an upper pipe 1242, and the upper pipe 1242 and the lower pipe 1241 have different dimensions. Generally, it is required that the inner diameter of the lower pipe 1241 is smaller than the inner diameter of the upper pipe 1242. The bridging pipe 101 of this invention is arranged at the connection between the lower pipe 1241 and the lower pipe 1242. Based on this design, fallen leaves can be prevented from accumulating at the connection between the bridging pipe 101 and the internal pipe 124.

[0081] In this invention, the partition plate 121 is also provided with a protective mechanism, and each protective mechanism corresponds to a power mechanism; the protective mechanism includes a protective arc plate 123; the protective arc plate 123 is spaced apart from the internal pipe 124; one end of the protective arc plate 123 is connected to the partition plate 121, and the other end extends freely along the axis parallel to the internal pipe 124; the protective arc plate 123 is spaced apart from the bottom of the casing 1; based on this design, the air inlet end at the lower end of the fan 13 forms an independent space, which serves as a separation function.

[0082] In this invention, the air inlet end of the fan 13 is provided with a filter unit, the filter unit includes a filter mounting plate 122, and the filter mounting plate 122 is provided with a detachable filter. The filter unit plays a good role in separating and isolating, preventing fallen leaves from directly entering the impeller of the fan 13, thereby reducing the probability of impeller damage and helping to extend the service life of the fan 13.

[0083] In this invention, the suction pipe includes an external pipe 2, one end of which is connected to an internal pipe 124, and the other end is connected to a blow-suction pipe 3. The external pipe 2 can be a connecting hose to facilitate the subsequent swinging of the suction pipe. In this invention, the internal pipe 124 protrudes from the housing 1. Based on this design, the connection between the external pipe 2 and the internal pipe 124 is facilitated.

[0084] In this invention, the end of the internal pipe 124 can be provided with an external thread, and the internal pipe 124 can be installed and fixed on the upper end of the housing 1 by an external locking flange or nut.

[0085] A method of using the leaf-cleaning blower and suction unit, the method comprising the following steps:

[0086] When air blowing is required, the control drive 16 moves the plug 15 to the upper opening of the internal pipe 124, thereby blocking the opening of the internal pipe 124 with the plug 15.

[0087] Then control the control valve to connect the air outlet of the fan 13 to the bridging pipe 101;

[0088] Then start the blower motor 14; the airflow enters the equipment compartment 11 through the air inlet opening 111, enters the garbage compartment 12 through the air vent on the partition 121, then enters the air inlet of the blower 13, enters the internal pipe 124 through the control valve and bridging pipe 101, and then is blown out through the suction pipe.

[0089] When suction operation is required, the control drive 16 drives the blockage 15 to move towards the side of the partition 121, so that the blockage 15 seals the air vent.

[0090] Then control the control valve to connect the air outlet of the fan 13 with the equipment compartment 11;

[0091] Finally, the blower motor 14 is started, and the airflow enters through the suction pipe, enters the internal pipe 124, and enters the garbage compartment 12 through the opening in the middle area of ​​the internal pipe 124. The airflow impacts the bottom of the blockage 15 to relieve pressure, and the kinetic energy of the garbage mixed in the airflow is partially absorbed. It falls to the bottom of the garbage compartment 12 by gravity. Some suspended matter is blocked by the protective arc plate 123 and further settles under the action of gravity. The airflow enters through the air inlet of the blower 13, enters the equipment compartment 11 through the control valve, and enters the atmosphere through the air inlet opening 111.

[0092] Based on the above usage method, impurity suction and purging operations can be achieved.

[0093] The leaf cleaning blower and suction unit disclosed in this invention can be designed as a shoulder strap or mounted on a vehicle.

[0094] Example 1:

[0095] The interior of the housing 1 is hollow, forming an inner cavity; the housing 1 provides installation space and protection for various components, and the air intake opening 111 on it ensures that the equipment compartment 11 is connected to the outside atmosphere, maintains air pressure balance and facilitates heat dissipation.

[0096] The partition 121 divides the interior cavity into an equipment compartment 11 and a waste compartment 12.

[0097] It achieves dry and wet separation, prevents dust and moisture in the waste compartment 12 from entering the equipment compartment 11, protects the internal precision components, and serves as the mounting reference surface for various functional openings and components.

[0098] The power unit includes two spaced-apart power mechanisms, each of which contains a fan 13. The fan 13 is arranged inside the equipment compartment 11, and its air inlet is connected to the waste compartment 12 through the partition 121.

[0099] The dual fans 13 provide powerful and adjustable airflow, supporting both blowing and suction modes. When one fan 13 fails, the other fan 13 can maintain basic operation, improving equipment reliability and operational efficiency.

[0100] The piping unit includes a suction pipe and an internal pipe 124. The internal pipe 124 is arranged inside the housing 1, and the suction pipe is connected to the waste compartment 12 through the internal pipe 124.

[0101] The internal pipe 124 serves as a common airflow channel, while the suction pipe serves as an external working end. The two work together to achieve the intake or expulsion of fallen leaves. The internal pipe 124 protrudes from the casing 1, which facilitates the quick assembly and disassembly of the external pipe 2.

[0102] The bridging mechanism includes an external discharge pipe and a bridging pipe 101, which are respectively connected to the air outlet of the fan 13 and the equipment compartment 11 and the internal pipe 124.

[0103] The bridging mechanism provides two independent paths for the air outlet of the fan 13. By switching paths, the blowing and suction modes can be switched. The external exhaust pipe directly discharges the airflow into the equipment compartment 11, and the bridging pipe 101 guides the airflow to the internal pipe 124 for blowing operations.

[0104] The control unit 17 includes a control valve that controls the connection between the bridging pipe 101 or the exhaust pipe and the air outlet of the fan 13.

[0105] The control unit 17 precisely switches the airflow direction and completes the switching between blowing and suction modes with one click, ensuring continuous operation. The valve has good sealing performance to prevent airflow leakage and reduce efficiency.

[0106] The sealing mechanism includes a rubber plug 15 and a drive component 16. The drive component 16 can be a screw motor. The vertical cross section of the plug 15 is an inverted trapezoid. The drive component 16 can move the plug 15 to seal the end of the internal pipe 124 or the vent hole.

[0107] In the blowing mode, the internal pipe 124 is blocked, forcing the airflow to be blown out through the bridging pipe 101; in the suction mode, the vent is blocked, so that the airflow only enters from the suction pipe, while the bottom of the block is blocked to deflect the impact airflow and help the garbage settle.

[0108] The protective mechanism includes a protective arc-shaped plate 123, which is spaced apart from the internal pipe 124. One end is connected to the partition plate 121, and the other end extends freely with a gap between it and the bottom of the casing 1.

[0109] It prevents suspended particles from directly rushing towards the inlet of the fan 13, guides the airflow to swirl, and causes the particles to settle under the action of gravity, reducing the burden on the filter screen and improving filtration and settling efficiency.

[0110] The filter unit includes a filter mounting plate 122 and a detachable filter. The mounting plate is inserted into the air inlet of the fan 13. The filter unit intercepts debris and prevents the fan 13 blades from getting tangled and damaged. The detachable design facilitates quick cleaning or replacement of the filter and maintains stable operation of the equipment.

[0111] Detailed usage instructions

[0112] Blowing mode: Blocking 15 blocks the internal pipe 124, the control valve connects to the bridging pipe 101, the airflow passes through the air inlet opening 111, equipment compartment 11, vent, garbage compartment 12, fan 13, bridging pipe 101, internal pipe 124, and finally blows out from the suction pipe to achieve leaf blowing.

[0113] Suction mode: Block 15 seals the vent hole, the control valve connects to the exhaust pipe, the airflow enters from the suction pipe, enters the garbage compartment 12 through the side opening of the internal pipe 124, impacts the bottom of the block 15 to relieve pressure, the garbage settles, the airflow then returns to the equipment compartment 11 through the fan 13 and the exhaust pipe, and finally exits from the air inlet opening 111, completing the collection and filtration of fallen leaves.

[0114] Example 2:

[0115] One objective of this invention is to provide a single-tube blow-suction machine that does not require disassembling the blow-suction tube 3 during blow-suction switching. The blow-suction switching is electrically controlled, with one-button operation, making it simple to use.

[0116] The technical solution adopted in this invention is: a blower / vacuum machine, which has a blowing mode and a suction mode, the blower / vacuum machine including a housing 1.

[0117] The main function of the housing 1 is to store waste and provide installation positions for equipment such as the fan 13, air valve, and battery. The housing 1 has an internal pipe 124 with openings at both ends. A bridging pipe 101 is connected to each side of the internal pipe 124. Each bridging pipe 101 is connected to an air outlet of the fan 13. The housing 1 is divided into upper and lower parts by a partition 121. The upper part of the partition 121 is the equipment compartment 11, and the lower part is the waste compartment 12.

[0118] The equipment compartment 11 and the waste compartment 12 are connected by a vent in the middle, and airflow can enter the waste compartment 12 through the equipment compartment 11.

[0119] The garbage compartment 12 has protective arc-shaped plates 123 on both sides of the air inlet of the fan 13, which divide the garbage compartment 12 to prevent garbage from directly contacting the air inlet filter of the fan 13 when it is sucked in, thus reducing the risk of air inlet blockage 15.

[0120] The blower 13 is installed in the equipment compartment 11 at the top of the casing 1. The blower 13 is driven by a motor to generate airflow to suck up the garbage compartment 12 at the bottom of the casing 1.

[0121] Blow-and-suction pipe 3 is a pipe used for blowing air and sucking up garbage.

[0122] The control unit 17 changes the airflow direction by opening and closing, thereby achieving the switching of blowing and sucking modes.

[0123] The present invention has a dual-fan 13 structure, but a single-fan 13 structure can also be used.

[0124] Meanwhile, the power source includes, but is not limited to, plug-in and battery power.

[0125] like Figure 1As shown, the blow-and-suction integrated machine of the present invention includes a housing 1, a blow-and-suction pipe 3, and an external pipe 2; in the present invention, the external pipe 2 is generally a connecting hose.

[0126] The casing 1 has two shoulder straps for the operator to carry.

[0127] The operator holds the blow-suction pipe 3 to perform blow-suction operations. The blow-suction pipe 3 has operation buttons that can control the reversal of the air damper inside the machine and the start and stop of the motor.

[0128] like Figure 2 As shown, the body is divided into upper and lower parts by the partition 121, namely the equipment compartment 11 and the waste compartment 12.

[0129] The equipment compartment 11 has an air intake opening 111 at the rear; and the air intake opening 111 is equipped with an air intake grille.

[0130] The partition 121 is located at the upper end of the inner cavity, with three ventilation holes in the middle and circular holes on both sides for installing the fan 13.

[0131] The fan 13 is installed on the upper part of the partition 121. The air inlet of the fan 13 is coaxially installed with the circular holes on both sides of the partition 121. The air outlet of the fan 13 is connected to a two-position three-way ventilation valve. The two-position three-way ventilation valve can control the airflow from the air outlet of the fan 13 to blow upward or downward.

[0132] The fan motor 14 is directly connected to the fan 13.

[0133] A lead screw motor is fixed in the middle of the equipment compartment 11. There is a rubber plug 15 at the bottom of the lead screw motor. The rubber plug 15 can be moved up and down by the forward and reverse rotation of the lead screw motor.

[0134] The top partition 121 of the rubber plug 15 has three vent holes. When the rubber plug 15 moves to the top, it can block the vent holes. When the rubber plug 15 moves to the bottom, it can block the middle opening of the internal pipe 124.

[0135] The top left and right sides of the garbage compartment 12 are each designed with two arc-shaped protective arc plates 123. The arc-shaped protective arc plates 123 and the outer wall of the garbage compartment 12 form a columnar space. Inside the space, there is a filter screen mounting plate 122, on which a detachable filter screen is installed.

[0136] like Figure 3aAs shown, when blowing is required, first control the screw motor 16 to rotate forward, so that the rubber plug 15 moves down to the middle opening of the internal pipe 124 and blocks it; then control the two-position three-ventilation valve to connect the air outlet of the blower 13 with the internal pipe 124 to complete the air duct switching; finally start the blower motor 14, and the airflow enters the equipment compartment 11 through the grille ventilation holes, enters the garbage compartment 12 through the three ventilation holes in the middle of the partition 121, bypasses the arc-shaped protective arc plate 123, passes through the filter screen on the filter screen mounting plate 122 and enters the air inlet of the blower 13, enters the internal pipe 124 through the two-position three-ventilation valve, and is blown out from the lower part of the blower pipe 3 after passing through the blow-suction pipe 3 and the external pipe 2 of the machine body.

[0137] like Figure 3b As shown, when suction operation is required, firstly, the screw motor is reversed to move the rubber plug 15 to the bottom of the partition 121, blocking the three ventilation holes in the middle of the partition 121; then, the two-position three-ventilation valve is controlled to connect the air outlet of the blower 13 with the equipment compartment 11, completing the air duct switching; finally, the blower motor 14 is started, and the airflow enters from the lower part of the blow-suction pipe 3, enters the internal pipe 124 through the blow-suction pipe 3 and the external connecting pipe 2 of the machine body, and enters the garbage compartment 12 through the middle opening of the internal pipe 124. The airflow impacts the bottom of the rubber plug 15 to relieve the pressure, and the kinetic energy of the garbage mixed in the airflow is partially absorbed. It falls to the bottom of the garbage compartment 12 by gravity. Some suspended matter is blocked by the arc-shaped protective arc plate 123 and further settles under the action of gravity. The airflow enters the air inlet of the blower 13 through the filter screen on the filter screen mounting plate 122, enters the equipment compartment 11 through the two-position three-ventilation valve, and enters the atmosphere through the grille ventilation holes.

[0138] Obviously, the specific implementation of this invention is not limited to the above-described methods. Any non-substantial improvements made using the inventive concept and technical solution of this invention are within the protection scope of this invention.
