Description

Technical Field

[0001] This invention relates to the field of engine technology, and specifically to an energy-saving engine for garden machinery. Background Technology

[0002] Garden machinery refers to mechanical equipment used for landscaping, garden construction, and garden maintenance, such as chainsaws, edge trimmers, edging machines, hedge trimmers, brush cutters, grass combers, high-branch machines, leaf suction machines, lawn mowers, and lawn trimmers.

[0003] The engine is a crucial component of various garden machinery, serving as the primary power source. Currently, most mobile garden machinery, such as lawnmowers and lawn wrenches, uses general-purpose engines. Due to the relatively humid environment of garden areas, increased moisture content in the air reduces gas density, resulting in less oxygen entering the cylinder and slower combustion of the air-fuel mixture. This can weaken engine power output, hinder acceleration, and lead to fuel waste. Simultaneously, humid air can cause air filters to become damp and clump, increasing intake resistance, affecting airflow efficiency, and obstructing smooth airflow into the combustion chamber, causing engine instability. If humid air condenses into liquid water in the intake manifold and is drawn into the cylinder in large quantities, it can cause serious mechanical damage such as "cylinder impact" (piston hitting liquid water, causing connecting rod bending). Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide an energy-saving engine for garden machinery to solve the problem that when the moisture content in the air increases due to the relatively humid environment of the garden area, the gas density decreases, resulting in a reduction in the amount of oxygen entering the cylinder, a slower combustion speed of the air-fuel mixture, which easily leads to a weakening of engine power output and a lack of acceleration, thus wasting fuel energy.

[0005] This invention is achieved through the following technical solution: An energy-saving engine for garden machinery includes an engine body, an air filter mechanism, and a generator. Both the engine body and the air filter mechanism have an air inlet and an air outlet. The air outlet of the air filter mechanism is connected to the air inlet of the engine body. The engine body drives the generator to generate electricity. The air filter mechanism includes a rotating rod and a first tube, a second tube, and a third tube arranged coaxially with the rotating rod from the inside out. A first cleaning section is formed between the rotating rod and the first tube. A filtering section is formed between the first and second tubes. A second cleaning section is formed between the second and third tubes. A filter plate is provided within the filtering section. The air inlet of the air filter mechanism is located between the filter plate and the second tube, and the air outlet of the air filter mechanism is located between the first tube and the filter plate. It also includes filter paper and a driving mechanism. The filter paper is vertically arranged along the side wall perpendicular to the rotating rod. There are multiple sheets of filter paper, which are arranged in a ring around the center line of the rotating rod. The side walls of the first tube, the filter plate, and the second tube are each formed with a corresponding opening that matches the multiple filter papers. The multiple filter papers pass through the multiple openings formed by the side walls of the first tube, the filter plate, and the second tube. The driving mechanism is used to drive the multiple filter papers to move along the multiple openings formed by the side walls of the first tube, the filter plate, and the second tube. Both the first and second filtration sections are provided with a cleaning mechanism for cleaning the filter paper.

[0006] Furthermore, the air filter mechanism is connected to a cover at both its upper and lower ends. The lower end of the upper cover above the first cleaning section has an upward-facing recess that forms multiple first grooves corresponding to multiple filter papers. The lower end of the upper cover above the second cleaning section has an upward-facing recess that forms multiple second grooves corresponding to multiple filter papers. The drive mechanism includes a first motor, connecting rods, and springs. Soft rubber strips are connected to the upper edges of multiple filter papers. One end of each soft rubber strip is located in a first groove, and the other end is located in a second groove. The first motor is connected to the cover, and the output shaft of the first motor passes through the cover and connects to the rotating rod. Multiple connecting rods are provided, and one end of each connecting rod can be rotatably connected to a non-central position on the upper end of the rotating rod. The other end of each connecting rod is connected to one end of each soft rubber strip. Multiple springs are provided, and both ends of each spring are respectively connected to the other end of each soft rubber strip and the edge of the second cleaning section.

[0007] Furthermore, the drive mechanism also includes a controller and a flow meter. The flow meter is connected to the engine intake port and electrically connected to the controller. The first motor is electrically connected to the controller, and the controller is electrically connected to the generator.

[0008] Furthermore, the cleaning mechanism includes a second motor, a reciprocating screw, and a cleaning brush. The reciprocating screw is vertically arranged, the second motor is connected to the cover, and the output shaft of the second motor is connected to one end of the reciprocating screw. The cleaning brush is slidably connected to the reciprocating screw. The end wall of the first slide groove near the rotating rod and the end wall of the second slide groove away from the second cleaning part are both connected to a first electrode plate. The two ends of the soft rubber strip are provided with second electrode plates. The communication between the first electrode plate and the second electrode plate enables the second motor to start.

[0009] Furthermore, the side walls of the rotating rod, the first tube, the second tube, and the third tube are all hollow and have interlayers, and the engine outlet is connected to a branch pipe, with the interlayers communicating with the branch pipes.

[0010] The beneficial effects of this invention are as follows: When using an energy-saving garden machinery engine of the present invention to drive garden machinery, the air filter mechanism can be cleaned at the same time, which to a certain extent ensures the air filtration efficiency of the air filter mechanism, thereby reducing the possibility that the filter paper will be affected by impurities, resulting in low intake efficiency of the main engine, and improving fuel combustion efficiency to a certain extent, thus making the engine more efficient and saving energy to a certain extent.

[0014] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0015] Please see Figure 1-5This invention provides a technical solution for an energy-saving garden machinery engine: an energy-saving garden machinery engine includes an engine body 1, an air filter mechanism 3, and a generator 2. Both the engine body 1 and the air filter mechanism 3 are provided with an air inlet and an air outlet. The air outlet of the air filter mechanism 3 is connected to the air inlet of the engine body 1. The engine body 1 drives the generator 2 to generate electricity. The air filter mechanism 3 includes a rotating rod 4 and a first tube 5, a second tube 6, and a third tube 7 arranged coaxially with the rotating rod 4 from the inside to the outside. A first cleaning section 51 is formed between the rotating rod and the first tube 5. A filtering section 61 is formed between the first tube 5 and the second tube 6. A second cleaning section 71 is formed between the second tube 6 and the third tube 7. A filter plate 62 is provided inside the filtering section 61. The air inlet of the air filter mechanism 3 is located between the filter plate 62 and the second tube, and the air outlet of the air filter mechanism 3 is located between the first tube 5 and the filter plate 62. It also includes filter paper 8 and a driving mechanism 9. The filter paper 8 is vertically arranged along the side wall perpendicular to the rotating rod 4. There are multiple sheets of filter paper 8, which are arranged in a ring around the center line of the rotating rod 4. The side walls of the first tube 5, the filter plate 62 and the second tube 6 are each formed with a plurality of openings 82 that match the plurality of filter papers 8. The plurality of filter papers 8 pass through the plurality of openings 82 formed by the side walls of the first tube 5, the filter plate 62 and the second tube 6. The driving mechanism 9 is used to drive the plurality of filter papers 8 to move along the plurality of openings 82 formed by the side walls of the first tube 5, the filter plate 62 and the second tube 6. The first filter section 61 and the second filter section 61 are each provided with a cleaning mechanism 10, which is used to clean the filter paper 8.

[0016] When using an energy-saving garden machinery engine of the present invention to drive garden machinery, the engine is started. Since both the engine body 1 and the air filter mechanism 3 are provided with an air inlet and an air outlet, the air inlet of the engine body 1 draws in air, causing the air to pass through the air filter mechanism 3. The air enters from between the filter plate 62 and the second tube 6, is adsorbed and filtered by the filter paper 8, passes through the filter plate 62, and flows through the space between the filter plate 62 and the first tube 5 to the air outlet of the air filter mechanism 3. This structure achieves air filtration.

[0017] When the engine is running, a portion of the filter paper 8 is located in the first cleaning section 51. The cleaning mechanism 10 in the first cleaning section 51 cleans the filter paper 8 located in the first cleaning section 51. At this time, another portion of the filter paper 8 is located in the filter section 61 for filtering the intake air. After the filter paper 8 has been used for a period of time, the drive mechanism 9 drives the filter paper 8 to move, so that the filter paper 8 located in the filter section 61 moves to the second cleaning section 71. At this time, the filter paper 8 that has been cleaned in the first cleaning section 51 is driven into the filter section 61 for filtration. Then, the filter paper 8 in the second cleaning section 71 is moved into the filter section 61 again. This cycle continues, so that when a portion of the filter paper 8 is being cleaned, it does not affect the filtering function of the other portion of the filter paper 8.

[0018] With this structure, when using an energy-saving garden machinery engine of the present invention to drive garden machinery, the air filter mechanism 3 can be cleaned at the same time, which to a certain extent ensures the air filtration efficiency of the air filter mechanism 3, thereby reducing the possibility that the filter paper 8 will be affected by impurities and thus the intake efficiency of the engine body 1 will be low. It also improves the fuel combustion efficiency to a certain extent, thereby making the engine more efficient and saving energy to a certain extent.

[0019] Specifically, the multiple filter papers are arranged closely together, which allows for better air filtration.

[0020] In this embodiment: The upper and lower ends of the air filter mechanism 3 are both connected to a cover 31. The lower end of the upper cover 31 above the first cleaning section 51 has an upward-facing recess that corresponds to a plurality of filter papers 8, forming a plurality of first grooves 52. The lower end of the upper cover 31 above the second cleaning section 71 has an upward-facing recess that corresponds to a plurality of filter papers 8, forming a plurality of second grooves 72. The drive mechanism 9 includes a first motor 91, a connecting rod 92, and a spring 93. Soft adhesive strips 81 are connected to the upper edges of the plurality of filter papers 8, and one end of each soft adhesive strip 81 corresponds to a portion of the filter paper 8. The first slide groove 52 is located in the second slide groove 72, and the other end is located in the second slide groove. The first motor 91 is connected to the cover 31, and the output shaft of the first motor 91 passes through the cover 31 and is connected to the rotating rod 4. There are multiple connecting rods 92, and one end of each connecting rod 92 can be rotatably connected to the non-center position of the upper end of the rotating rod 4. The other end of each connecting rod 92 is connected to one end of each of the multiple soft rubber strips 81. There are multiple springs 93, and the two ends of each spring 93 are respectively connected to the other end of each of the multiple soft rubber strips 81 and the edge of the second cleaning part 71.

[0021] The first motor 91 is started, and its rotation drives the connecting rod 92 to move in a circular motion along the center line of the rotating rod 4, thereby moving the connecting rod 92. Since one end of the flexible rubber strip 81 is located in the first slide groove 52 and the other end is located in the second slide groove 72, the connecting rod 92 can drive one end of the flexible rubber strip 81 to move along the first slide groove 52. The movement of the flexible rubber strip 81 causes the other end of the flexible rubber strip 81 to move along the second slide groove 72. Specifically, the flexible rubber strip 81 is made of a flexible and deformable material. While the flexible rubber strip 81 slides in the first slide groove 52 or the second slide groove 72, its shape changes according to its position in the first slide groove 52 or the second slide groove 72, and it always maintains a close fit with the first slide groove 52 or the second slide groove 72. This allows the flexible rubber strip 81 to drive the filter paper 8 in the filter section 61 towards the first cleaning section. 51 moves, and the filter paper 8 in the second cleaning section 71 moves towards the filter section 61. Since the two ends of the spring 93 are respectively connected to the other end of the soft rubber strip 81 and the edge of the second cleaning section 71, the movement of the other end of the second soft rubber strip 81 causes the spring 93 to stretch. When the filter paper 8 in the filter section 61 needs to be cleaned, the first motor 91 reverses, thereby releasing the tension on the soft rubber strip 81. The other end of the soft rubber strip 81 slides back along the second slide groove 72 under the drive of the spring 93, thereby moving the filter paper 8 in the filter section 61 to the second filter section 61, and moving the filter paper 8 in the first filter section 61 to the filter section 61. With this structure, the drive mechanism 9 can be used to drive multiple filter papers 8 to move one-to-one along multiple openings 82 formed by the side walls of the first tube 5, the filter plate 62, and the second tube 6.

[0022] Specifically, the filter paper 8 is connected with a clip that cooperates with the opening 82. This structure reduces the amount of air entering the first cleaning section 51 and the second cleaning section 71 from the opening 82.

[0023] In this embodiment: the drive mechanism 9 further includes a controller and a flow meter. The flow meter is connected to the engine air inlet and is electrically connected to the controller. The first motor 91 is electrically connected to the controller, and the controller is electrically connected to the generator 2.

[0024] When the engine body 1 is started, the engine body 1 drives the generator 2 to generate electricity, which in turn enables the controller and flow meter to operate. The flow meter measures the air intake of the engine body 1 and sends an electrical signal to the controller. When the air intake of the engine body 1 is lower than the amount required for the fuel in the engine body 1 to burn completely, the controller receives the electrical signal and drives the first motor 91 to operate, causing the first motor 91 to move the filter paper 8. In this structure, the air intake of the engine body 1 is used to determine whether the filter paper 8 needs to be cleaned, which to a certain extent ensures the air intake of the engine body 1, thereby ensuring the fuel combustion efficiency to a certain extent.

[0025] In this embodiment: the cleaning mechanism 10 includes a second motor 101, a reciprocating screw 102, and a cleaning brush 103. The reciprocating screw 102 is vertically arranged. The second motor 101 is connected to the cover 31. The output shaft of the second motor 101 is connected to one end of the reciprocating screw 102. The cleaning brush 103 is slidably connected to the reciprocating screw 102. The end wall of the first slide groove 52 near the rotating rod 4 and the end wall of the second slide groove 72 away from the second cleaning part 71 are both connected to a first pole piece. The two ends of the soft rubber strip 81 are provided with second pole pieces. The communication between the first pole piece and the second pole piece can start the second motor 101.

[0026] The first motor 91 is started, which drives one end of the flexible rubber strip 81 to slide towards the end wall of the first slide groove 52 near the rotating rod 4 until the end of the flexible rubber strip 81 abuts against the end wall of the first slide groove 52 near the rotating rod 4. This connects the second electrode plate of the flexible rubber strip 81 with the first electrode plate of the end wall of the first slide groove 52 near the rotating rod 4, thereby starting the second motor 101 in the first cleaning section 51. This drives the reciprocating screw 102 to rotate, thereby driving the cleaning brush to move up and down reciprocally to clean the filter paper 8 located in the first filtering section 61. When the first motor 91 reverses... When the first motor 91 rotates, it drives the other end of the flexible rubber strip 81 to slide towards the end wall of the second slide groove 72 away from the filter part 61 until the other end of the flexible rubber strip 81 abuts against the end wall of the second slide groove 72 away from the filter part 61. This causes the second electrode connected to the other end of the flexible rubber strip 81 to connect with the first electrode connected to the end wall of the second slide groove 72 away from the filter part 61. This causes the second motor 101 in the second cleaning part 71 to start, driving the reciprocating screw 102 to rotate, thereby driving the cleaning brush to move up and down reciprocally to clean the filter paper 8 located in the second filter part 61.

[0027] With this structure, the filter paper 8 can be cleaned when it moves to the corresponding first cleaning section 51 or second cleaning section 61, without the first cleaning section 51 and the second cleaning section 71 needing to clean simultaneously, thus saving energy to a certain extent.

[0028] Specifically, one end of the cleaning brush is provided with a through hole, the through hole is connected to a slider, the reciprocating screw 102 passes through the through hole, and the slider is slidably engaged in the tooth groove of the reciprocating screw 102.

[0029] In this embodiment: the side walls of the rotating rod 4, the first tube 5, the second tube 6 and the third tube 7 are all hollow and have a sandwich structure. The engine outlet is connected to a branch pipe 11. The sandwich structure is connected to the branch pipe 11. After the engine body 1 is started, the hot gas is discharged and flows through the sandwich structure, so that the first cleaning part 51 and the second cleaning part 71 are kept at a high temperature. To a certain extent, the filter paper 8 can be dried, and to a certain extent, the possibility of water vapor and dust mixing and clumping on the filter paper 8 and causing the filter paper 8 to clump together can be reduced.

[0030] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
