Description

Technical fields:

[0001] This utility model belongs to the technical field of lawnmowers, specifically referring to a starter that is easy to clean. Background technology:

[0002] A starter is a device used to start an engine or motor. There are two main types of starter motors: electric starters and manual starters. Manual starters are widely used in small lawnmowers because of their simple structure and low cost.

[0003] Because of the working environment of lawnmowers (grass, debris, dust), accumulated grass clippings, mud and other debris can easily adhere to the pull rope and enter the starter. When cleaning the starter, it is necessary not only to clean the starter shell, but also to disassemble the starter shell to clean the internal impurities. The cleaning is inconvenient and needs to be improved. Utility model content:

[0004] The purpose of this invention is to provide a starter that is easy to clean, so as to solve the technical problems mentioned in the background art.

[0005] This utility model is implemented as follows:

[0006] A starter that is easy to clean includes a housing, a pull plate rotatably connected to the housing, a pull rope wound on the pull plate, and a handle on the pull rope. The housing has a rope outlet and a baffle. The baffle and the housing are joined to form a dustproof channel, which communicates with the rope outlet. The housing is equipped with a dust removal fan, and the air outlet of the dust removal fan faces the end of the dustproof channel away from the rope outlet.

[0007] By adopting the above technical solution, during the process of starting the generator, the operator pulls out the pull rope with the handle, starts the motor, the pull plate rewinds the pull rope, and the dust removal fan rotates to blow away the impurities attached to the pull rope, reducing the amount of impurities entering the starter housing. This helps to reduce the frequency of cleaning the starter housing, so that daily maintenance only requires cleaning the debris accumulated on the surface of the starter housing, without the need for frequent disassembly of the housing, greatly reducing the workload.

[0008] Preferably, two guide rollers are rotatably connected to the housing, and a rope is threaded between the two guide rollers. The gap is for the rope to be threaded through.

[0009] By adopting the above technical solution, the pull rope is abutted by two guide rollers, which helps to reduce the wear between the pull rope and the rope outlet of the shell and extend the rope life.

[0010] Preferably, a drive wheel is coaxially connected to the dust collector fan, and a drive wheel is coaxially connected to one of the guide rollers. A belt is tensioned around the drive wheel and the drive wheel.

[0011] By adopting the above technical solution, when the rope is pulled out or wound up, the guide roller rotates, and the rotation of the guide roller drives the drive wheel to rotate. The drive wheel drives the dust collector fan to rotate and blow air through the cooperation between the belt and the transmission wheel, which helps to reduce energy consumption.

[0012] Preferably, a scraper is rotatably connected to the housing, the scraper is correspondingly arranged with the guide roller, the rotation axis of the scraper is coaxial with the rotation axis of the corresponding guide roller, and the guide roller drives the scraper to rotate through frictional damping with the scraper.

[0013] By adopting the above technical solution, when the air is humid or there is mud on the pull rope, the guide roller rotates. The guide roller drives the scraper head to move closer to the rope threading gap through friction between the guide roller and the scraper head. The scraper head then comes into contact with the surface of the pull rope to scrape off the impurities on the surface of the pull rope, reducing the amount of stubborn impurities on the surface of the pull rope from entering the starter housing.

[0014] Preferably, the housing is provided with a limiting part, the limiting part is located on the rotation path of the scraper, the limiting part is located on the side of the scraper head near the rope outlet, the limiting part is located on opposite sides of the rope threading gap, and the scraper head is located on the side of the guide roller away from the rope threading gap.

[0015] By adopting the above technical solution, when the rope is pulled out, the ends of the two guide rollers that are close to each other rotate away from each other in the direction away from the rope outlet, while the end of the guide roller that is away from the rope threading gap rotates towards the rope outlet. The guide roller drives the scraper head to rotate towards the rope outlet through friction between the guide roller and the scraper head. The limiting part abuts against the scraper head to restrict the movement of the scraper head, so that the scraper head and the rope are spaced apart during the rope pulling process, which helps to reduce the friction on the rope during the pulling process. When the rope is rewinding, the guide roller rotates in the opposite direction, and the guide roller drives the scraper head to move close to the rope threading gap to abut against the rope and scrape off the impurities on the rope.

[0016] Preferably, the baffle is hinged to the housing, and the baffle is provided with a magnetic element, which attracts the housing to position the baffle relative to the housing.

[0017] By adopting the above technical solution, when the starter needs to be cleaned, the baffle is rotated away from the housing to open the dustproof channel, which facilitates cleaning of the inside of the dustproof channel. After cleaning, the baffle is rotated towards the housing, and the magnetic component attracts and fixes the housing.

[0018] Preferably, the baffle has an opening that extends through the baffle in a direction perpendicular to the rotation axis of the baffle. The opening communicates with the dustproof channel and allows the handle to be inserted into it. The magnetic component attracts the handle.

[0019] By adopting the above technical solution, after the handle is inserted into the opening, it is fixed by a magnetic component, making it easy for users to quickly find the handle when using it.

[0020] The outstanding advantages of this utility model compared to the prior art are:

[0021] 1. This utility model uses a dust removal fan to blow away impurities attached to the pull rope, reducing the amount of impurities entering the starter housing. This reduces the frequency of cleaning the starter housing, so that daily maintenance only requires cleaning the debris accumulated on the surface of the starter housing, without the need for frequent disassembly of the housing, thus greatly reducing the workload.

[0022] 2. This utility model uses a scraper head to scrape off impurities from the surface of the pull rope, reducing the amount of stubborn impurities from the pull rope surface from entering the starter housing.

[0023] 3. The limiting part of this utility model abuts against the scraper head to restrict the movement of the scraper head, so that the scraper head and the pull rope are spaced apart during the pulling process, which helps to reduce the friction on the pull rope during the pulling process; when the pull rope is rewinding, the guide roller rotates in the opposite direction, and the guide roller drives the scraper head to move close to the rope threading gap to abut against the pull rope and scrape off the impurities on the pull rope.

[0029] The present invention will be further described below with reference to specific embodiments. See also: Figure 1 —4:

[0030] This application discloses a starter that is easy to clean up. See also: A starter that is easy to clean up. Figure 1 and Figure 2 The device includes a housing 1, a pull plate 2, a pull rope 3, and a handle 4. The pull plate 2 is located inside the housing 1 and is rotatably connected to the housing 1. The pull plate 2 contains a coil spring that drives the pull plate 2 to rotate and reset. The pull rope 3 is wound around the pull plate 2. The housing 1 has a rope outlet 11. The distribution direction of the rope outlet 11 and the pull plate 2 is perpendicular to the rotation axis of the pull plate 2. One end of the pull rope 3 passes through the rope outlet 11. The handle 4 is fixedly connected to the end of the pull rope 3 that passes through the rope outlet 11.

[0031] See Figure 2 and Figure 3 A baffle 5 is hinged to the end face of the housing 1 where the rope outlet 11 is located. The hinge axis of the baffle 5 is parallel to the rotation axis of the pull plate 2. The baffle 5 and the housing 1 are joined to form a dustproof channel 51. The dustproof channel 51 has an L-shaped cross-section perpendicular to the rotation axis of the pull plate 2. The dustproof channel 51 is connected to the rope outlet 11. A magnetic component 52, which is a magnet 521, is fixed on the baffle 5. The magnet 521 is used to attract the housing 1, thus fixing the housing 1 and the baffle 5. During cleaning, the baffle 5 can be opened to facilitate cleaning of the inside of the dustproof channel 51.

[0032] See Figure 2 and Figure 3 An opening 53 is provided on the baffle 5, located on the side of the housing 1 near the magnet 521. The extension direction of the opening 53 is perpendicular to the distribution direction of the housing 1 and the baffle 5. The opening 53 extends through the baffle 5 in a direction perpendicular to the hinge axis of the baffle 5 towards the housing 1. The opening 53 is connected to the dustproof channel 51. The rope exits through the outlet 11, the dustproof channel 51, and the opening 53 in sequence. After the rope 3 is wound up, the handle 4 is inserted into the opening 53. The handle 4 is an iron handle, and the magnet 521 is used to attract the handle 4. The magnet 521 simultaneously fixes the handle 4 and the baffle 5, making fixing convenient.

[0033] See Figure 3 and Figure 4A dust collector fan 6 is fixed on the housing 1. The dust collector fan 6 is located in the dustproof channel 51. The dust collector fan 6 includes a housing 61, a rotating shaft 62 and several fan blades 63. The housing 61 is fixed on the housing 1. The rotating shaft 62 is rotatably connected to the housing 61. The rotation axis of the rotating shaft 62 is parallel to the rotation axis of the pull plate 2. Several fan blades 63 are arranged around the rotating shaft 62 and are fixed on the rotating shaft 62. The housing 1 has an air inlet 611 and an air outlet 612. The distribution direction of the air inlet 611 and the rotating shaft 62 is parallel to the rotation axis of the rotating shaft 62, and the distribution direction of the air outlet 612 and the rotating shaft 62 is perpendicular to the rotation axis of the rotating shaft 62. The air outlet 612 faces the end of the dustproof channel 51 away from the rope outlet 11. The pull rope 3, which passes through the rope outlet 11, is located on the side of the housing 61 near the air outlet 612. The rotating shaft 62 drives the fan blade 63 to rotate, so that the air is blown out from the air outlet 612, blowing the grass clippings and dust attached to the pull rope 3 away from the pull rope 3 and blowing them towards the end of the dustproof channel 51 away from the rope outlet 11. This helps to reduce the entry of dust, grass clippings and other impurities into the housing 1 through the rope outlet 11.

[0034] See Figure 3 and Figure 4 Two guide rollers 7 are rotatably connected to the housing 1. Both guide rollers 7 are located inside the dustproof channel 51. The guide rollers 7 are located on the side of the housing 61 near the air outlet 612. The distribution direction of the two guide rollers 7 is perpendicular to the hinge axis of the baffle 5. The rotation axis of the two guide rollers 7 is parallel to the hinge axis of the baffle 5. The two guide rollers 7 are spaced apart and spliced ​​together to form a rope threading gap 71. The rope threading gap 71 allows the pull rope 3 to pass through. The two guide rollers press against the pull rope 3. The rotation of the pull rope 3 drives the guide rollers 7 to rotate.

[0035] By pressing the pull rope 3 against the guide roller 7, it is beneficial to reduce the friction between the pull rope 3 and the inner wall of the rope outlet 11 during the pulling and winding process, which helps to reduce the wear of the pull rope 3 and improve the service life of the pull rope 3.

[0036] See Figure 3 and Figure 4 One of the guide rollers 7 has a drive wheel 73 coaxially fixed on it. In this embodiment, the drive wheel 73 is located near the guide roller 7 of the outer shell 61. A transmission wheel 621 is coaxially fixed on the rotating shaft 62. A belt 72 is tensioned around the transmission wheel 621 and the drive wheel 73. The rotation of the drive wheel 73 drives the transmission wheel 621 to rotate through the belt 72, which in turn drives the rotating shaft 62 to rotate, so that the dust collector fan 6 works.

[0037] See Figure 3 and Figure 4A scraper head 74 is rotatably connected to the housing 1. The position and number of scraper heads 74 correspond one-to-one with the position and number of guide rollers 7. There are two scraper heads 74. The rotation axis of the scraper head 74 is coaxial with the rotation axis of the corresponding guide roller 7. The scraper head 74 is located on the side of the corresponding guide roller 7 away from the rope threading gap 71. The scraper head 74 is rotatably connected relative to the corresponding guide roller 7. The scraper head 74 abuts against the outer peripheral wall of the guide roller 7. The guide roller 7 drives the scraper head 74 to rotate closer to or away from the rope threading gap 71 through the frictional damping between the guide roller 7 and the scraper head 74. The end of the scraper head 74 close to the rope threading gap 71 abuts against the rope threading gap 71. A limiting part 12 is machined on the housing 1. The limiting part 12 protrudes from the housing 1. The position and number of the limiting part 12 correspond one-to-one with the position and number of scraper heads 74. The limiting part 12 is located on the rotation path of the corresponding scraper head 74. The limiting part 12 abuts against the corresponding scraper head 74 and limits the scraper head 74. The limiting part 12 is located on opposite sides of the rope threading gap 71.

[0038] During the pulling of the rope 3, the rope 3 drives the guide roller 7 to rotate. The part of the guide roller 7 away from the rope threading gap 71 rotates towards the rope threading gap 71 in the direction closer to the housing 1, thereby causing the scraper head 74 to tend to rotate towards the rope threading gap 71 in the direction closer to the housing 1. The limiting part 12 abuts against the corresponding scraper head 74 to prevent the scraper head 74 from abutting against the rope 3 during the pulling of the rope 3. During the winding of the rope 3, the rope 3 drives the guide roller 7 to rotate. The part of the guide roller 7 away from the rope threading gap 71 rotates towards the rope threading gap 71 in the direction away from the housing 1, thereby driving the scraper head 74 to tend to rotate towards the rope 3 in the direction away from the housing 1. The scraper head 74 abuts against the rope 3, which makes it easier to scrape off stubborn impurities attached to the rope 3, and to reduce the amount of impurities attached to the rope 3 entering the housing 1 in the case of heavy moisture.

[0039] Through the coordinated operation of the guide roller 7, the scraper head 74 and the limiting part 12, the pull rope 3 is guided and positioned. When applied to braiding the pull rope 3, the scraper head 74 can effectively comb the surface hairs to ensure that the hair flow direction is consistent, thereby improving the smoothness and reliability of the pull rope 3.

[0040] The implementation principle of the starter that is easy to clean in this application embodiment is as follows: the dust fan removes grass clippings and dust attached to the surface of the pull rope 3, and the scraper head 74 removes more stubborn impurities from the surface of the pull rope 3, reducing the amount of impurities entering the housing 1. This helps to reduce the accumulation of dust inside the housing 1, so that when cleaning the starter, it is not necessary to disassemble the housing 1. The cleaning can be mainly focused on the surface of the starter housing 1, which improves the convenience of cleaning the starter for the staff and thus improves the cleaning efficiency.

[0041] The above embodiments are only one of the preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes made in accordance with the shape, structure and principle of this utility model should be covered within the protection scope of this utility model.
