Mops, mop mechanisms, smart cleaning devices, and handheld cleaning devices

Abstract

This application provides a mop, a mop mechanism, an intelligent cleaning device, and a handheld cleaning device. The mop is adapted to the mop mechanism, which has a rotation axis. The mop has two or more mop parts, with a gap formed between adjacent mop parts. The gap is adapted to surround the outer periphery of the mop, and at least a portion of the gap is spirally arranged. By spirally arranging at least a portion of the gap in the mop, when the scraper blade is scraping the mop, the entire scraper blade will not simultaneously contact the edge of the mop located in the gap. Instead, a smaller portion of the scraper blade will simultaneously contact the edge of the mop located in the gap each time, reducing the contact area between the entire scraper blade and the edge of the mop located in the gap, thus reducing the interference between the scraper blade and the mop, and making the entire mop more stable during rotation.

Description

Technical Field

[0001] This application relates to the field of cleaning equipment accessories technology, and more specifically, to a mop, a mop mechanism, an intelligent cleaning device, and a handheld cleaning device. Background Technology

[0002] With the continuous development of cleaning equipment, cleaning equipment is widely used in people's lives. For example, there are robot vacuum cleaners and handheld cleaning devices. These cleaning devices are usually equipped with a mop mechanism. By rotating the mop mechanism relative to the surface to be cleaned, a better cleaning effect can be achieved. However, during the cleaning process, the dirty water on the mop usually needs to be removed. A few cleaning devices use a scraper to abut against the mop of the mop mechanism. When the mop rotates relative to the scraper, the scraper can scrape off the dirty water and dirt on the mop.

[0003] However, some mops are usually made by splicing, which creates long gaps at the joints. When the scraper passes through the gaps, the scraper and the mop at the edge of the gaps interfere with each other to a great extent, making the mop very unstable during rotation. Summary of the Invention

[0004] This application provides a mop, a mop mechanism, an intelligent cleaning device, and a handheld cleaning device to solve the above problems.

[0005] The embodiments of this application achieve the above objectives through the following technical solutions.

[0006] In a first aspect, embodiments of this application provide a mop, applicable to a mop mechanism, the mop mechanism having a rotation axis, the mop having two or more mop parts, a gap being formed between two adjacent mop parts, the gap being arranged around the outer periphery of the mop, and at least a portion of the gap being spirally arranged.

[0007] Secondly, this application provides a mop mechanism applicable to a cleaning device. The cleaning device includes a scraping component, which includes a scraper strip arranged in a preset direction. The mop mechanism includes a rotating component and a mop. The rotating component has a rotation axis adapted to be aligned with a predetermined direction. The mop is adapted to abut against the scraper strip. The mop is disposed on the outer periphery of the rotating component and has two or more mop portions. A gap is formed between two adjacent mop portions, and at least a portion of the gap is spirally arranged.

[0008] Thirdly, embodiments of this application provide an intelligent cleaning device, which includes a mobile chassis, a scraping component, and a mop mechanism provided in the first aspect. The mop mechanism is disposed at the bottom of the mobile chassis, and the scraping component includes a scraper strip, which is disposed along the rotation axis of the mop mechanism and abuts against the mop.

[0009] Fourthly, this application also provides a handheld cleaning device, which includes a handheld part, a scraping component, and a mop mechanism provided in the first aspect. The handheld part includes a handheld part and a mounting part connected together. A rotating component is rotatably connected to the mounting part. The scraping component includes a scraper, which is arranged along the rotation axis of the mop mechanism and connected to the mounting part, and the scraper abuts against the mop.

[0010] Compared to existing technologies, the mop, mop mechanism, intelligent cleaning device, and handheld cleaning device provided in this application, by arranging at least part of the gap between two adjacent parts of the mop in a spiral manner, ensure that when the scraper blade is scraping the mop, the entire scraper blade will not simultaneously contact the edge of the mop blade located in the gap. Instead, a small portion of the scraper blade will contact the gap at the same time, thereby reducing the amount of interference between the entire scraper blade and the edge of the mop blade located in the gap. This makes the entire mop blade more stable during rotation. Moreover, when the mop blade rotates relative to the scraper blade, the scraper blade intersects with the gap, effectively preventing the scraper blade from falling into the gap and causing the mop blade to jam.

[0021] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of the present application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort are within the scope of protection of the present application.

[0022] The inventor discovered that strip-shaped mops typically have advantages such as ease of processing and low cost. Therefore, when manufacturing ring-shaped mops, the two ends of the strip-shaped mop are connected to form a ring structure. However, due to limitations in the manufacturing process, gaps are formed at the joints of the two ends of the mop. The inventor found that because of these gaps, and because the direction of these gaps is roughly parallel to the direction of the scraper blade, when the mop is tensioned around the outer circumference of the rotating component, the gaps in the mop are widened under tension. When the scraper blade is scraping the mop, as it passes through the gap, the entire scraper blade is simultaneously positioned within the gap along with the mop. The edges of the squeegee abut against each other, causing significant interference and resulting in uneven mop rotation. This leads to excessive rotational resistance and unstable drive current in the motor that drives the mop. Because the squeegee has a large contact area with the gap when passing through it, the entire cleaning device may shake or vibrate. The squeegee may even get stuck in the gap of the mop, hindering its normal rotation and preventing it from rotating properly. In this process, the motor may even stall, causing the drive current to increase continuously, leading to overheating and burnout.

[0023] Therefore, after the inventors have put in creative effort, they have provided the technical solution in this application to solve the above-mentioned technical problems. Specifically, the embodiments of this application provide a mop, which is suitable for a mop mechanism. The mop mechanism has a rotation axis, and the mop has two or more mop parts. A gap is formed between two adjacent mop parts. The gap is arranged around the outer periphery of the mop, and at least a portion of the gap is spirally arranged.

[0024] By arranging at least a portion of the mop's slits in a spiral pattern, the entire scraper blade will not simultaneously contact the edge of the mop within the slit when scraping. This reduces the area of ​​the scraper blade in constant contact with the slit, significantly minimizing interference between the scraper blade and the edge of the mop. Consequently, the mop rotates more smoothly relative to the scraper blade. Because the scraper blade intersects with the slit, it can pass smoothly without getting stuck, preventing problems such as the scraper blade jamming the mop, which could lead to unstable motor drive current, motor stalling, or motor overheating and burnout. The technical solution is described in detail below:

[0025] Please see Figure 1 The mop mechanism 100 is suitable for cleaning devices, which can be intelligent cleaning devices or handheld cleaning devices. Intelligent cleaning devices can be robotic vacuum cleaners or wall cleaning robots, etc. The cleaning device includes a scraping component, which includes a scraper. The scraper is set in a preset direction and is used to abut against the mop 120. When the scraper and the mop 120 abut against each other, there is a certain amount of interference between them, but the scraper will not hinder the normal rotation of the mop 120. When the mop 120 rotates relative to the scraper, the scraper can scrape the surface of the mop 120 to remove sewage, dirt, etc. from the mop 120.

[0026] Please see Figure 1 In this embodiment, the mop mechanism 100 includes a rotating component 110 and a mop 120. The rotating component 110 has a rotation axis X, and a preset direction is consistent with the rotation axis X, that is, the preset direction is approximately parallel to the rotation axis X. The mop 120 is adapted to abut against the scraper. The mop 120 is disposed on the outer periphery of the rotating component 110 and includes at least two or more mop portions 125. A gap 121 is formed between two adjacent mop portions 125. The gap 121 is disposed around the outer periphery of the rotating component 110, that is, the gap 121 is disposed around the rotation axis X and located on the outer periphery of the rotating component 110. It should be noted that the gap 121 can be disposed around the entire outer periphery of the rotating component 110 or part of the outer periphery. At least a portion of the gap 121 is spirally arranged. The mop 120 can be tensioned on the outer periphery of the rotating component 110.

[0027] Please see Figure 2In this embodiment, the rotating assembly 110 includes a drive motor 113, a drive roller 111, and a rotating roller 112. The drive roller 111 and the rotating roller 112 are arranged side by side with a gap between them. The drive motor 113 is driven by the drive roller 111. The mop 120 is tensioned around the outer periphery of the drive roller 111 and the rotating roller 112. The mop 120 in the tensioned state has a roughly elliptical cylindrical structure, which allows the lower surface of the mop 120 to form a relatively flat surface, increasing the contact area between the lower surface of the mop 120 and the surface to be cleaned, and effectively enhancing the mopping effect of the mop 120. Specifically, the axes of the drive roller 111 and the rotating roller 112 can be roughly parallel, wherein the rotation axis X of the rotating assembly 110 is basically consistent with the axes of the drive roller 111 and the rotating roller 112. When the rotating assembly 110 rotates, it can drive the mop 120 to rotate approximately around the rotation axis X.

[0028] In some embodiments, the rotating assembly 110 may omit the rotating roller 112, and the mop 120 may be directly sleeved on the outer periphery of the drive roller 111 and have a generally cylindrical structure.

[0029] Please see Figure 1 and Figure 2 In this embodiment, the mop 120 is generally formed into a cylindrical structure. The mop 120 includes at least two or more mop parts 125. It should be noted that each mop part 125 refers to a certain part on a mop structure. That is, multiple mop parts 125 are actually different parts on a single mop. A gap 121 is formed between two adjacent mop parts 125. The entire gap 121 can be spirally arranged around the rotation axis X, or a portion of the gap 121 can be spirally arranged around the rotation axis X.

[0030] In this embodiment, the mop 120 includes a first edge 1211 and a second edge 1212. A slit 121 can spiral from the first edge 1211 to the second edge 1212 around the rotation axis X. Specifically, the slit 121 can spiral from a first position point on the first edge 1211 to a second position point on the second edge 1212. The line connecting the first and second position points can be parallel to or intersect the rotation axis X. The slit 121 can spiral at least 1 / 2 turn or more around the rotation axis X on the outer periphery of the mop 120. For example, as shown... Figure 1 and Figure 2 As shown, the slit 121 can spiral around the rotation axis X multiple times around the outer circumference of the mop 120, and each mop part 125 is spirally arranged and adjacent to each slit 121. The first position point and the second position point can be located on the same side of the mop 125 or on opposite sides.

[0031] In some embodiments, the slit 121 may be spirally arranged only in a portion of the surface of the mop 120. For example, the slit 121 may spiral from a first position on the first edge 1211 of the mop 120 to a second position on the second edge 1212 of the mop 120, with the line connecting the first and second positions forming an angle less than 90° with the axis of rotation X. When the mop 120 rotates to a preset position, the first and second positions may simultaneously be located on either the upper or lower surface of the mop 120.

[0032] In some embodiments, the inner surfaces of two or more mop portions 125 are connected by adhesive or sewing and together form a cylindrical structure to facilitate tension on the outer periphery of the rotating assembly 110. For example, an adhesive layer can be provided on the inner surface of the mop 120. For example, the inner surfaces of two or more mop portions 125 are provided with adhesive layers, which connect each mop portion 125. After the adhesive layer solidifies, it forms a structure with a certain degree of flexibility. The edges of the mop portions 125 are sewn to the adhesive layer to improve the connection strength between the mop portions 125 and the adhesive layer and prevent the edges of the mop portions 125 from separating from the adhesive layer due to delamination.

[0033] In some manufacturing methods, the tubular mop 120 can be made by spirally wrapping a strip-shaped mop structure around the outer periphery of the tubular structure. The strip-shaped mop structure can be spirally wound from one edge of the tubular structure to the other edge, so that the strip-shaped mop structure can form a roughly tubular structure. Each spiral segment of the spiral mop 120 can be regarded as a mop part 125. A gap 121 is formed between every two adjacent mop parts 125. Multiple gaps 121 21 are interconnected and roughly form a spiral-shaped gap structure. Specifically, the mop 120 is roughly formed by applying at least one layer of adhesive to the inner surface of the cylindrical mop 120 or by sewing the mop parts 125 on opposite sides of each gap 121. It should be noted that although the two mop parts 125 are sewn or glued together, there is still a gap 121 between adjacent mop parts 125. When the tension on the mop 125 is large, the width of the gap 121 will increase.

[0034] In some implementations, such as Figure 3 and Figure 4As shown, the gap 121 includes a first gap 1213 and a second gap 1214 that are connected. The first gap 1213 and the second gap 1214 can be spirally arranged in different directions around the rotation axis X. The end of the first gap 1213 away from the second gap 1214 can extend to the first edge 1211 of the mop 120, and the end of the second gap 1214 away from the first gap 1213 can extend to the second edge 1212. Specifically, the connection between the first gap 1213 and the second gap 1214 is located between the first edge 1211 and the second edge 1212. The first gap 1213 can spiral from a predetermined position between the first edge 1211 and the second edge 1212 in a first spiral direction to a second position of the second edge 1212, and the second gap 1214 can spiral from the predetermined position in a second spiral direction to a first position of the first edge 1211. For example, as shown... Figure 4 As shown, one end of the mop 120 can be roughly inverted "V" shaped, and the other end of the mop 120 can be roughly "V" shaped. The inverted "V" shaped end can be inserted into the other "V" shaped end, and an adhesive layer or seam can be applied to the inner surface of the mop 120 to connect the two ends. Furthermore, as... Figure 3 As shown, one end of the mop 120 can be roughly inverted "U" shaped, and the other end of the mop 120 can be roughly "U" shaped. The inverted "U" shaped end can be embedded into the other "U" shaped end. In this way, by setting the edge of one end of the mop 120 to a specific concave structure (e.g., "V" or "U" shaped structure) and the edge of the other end to a specific convex structure (e.g., inverted "V" or inverted "U" shaped structure), the shapes of the two ends of the mop 120 can be matched, and the two ends of the mop 120 can be spliced ​​together. That is, each end of the mop 120 serves as a mop part 125, and a first gap 1213 and a second gap 1214 are formed between the two mop parts 125.

[0035] This not only allows at least a portion of the slit 121 to be spirally arranged, but also reduces the processing difficulty of the mop 120. By enclosing a complete strip of mop 120, bringing the two ends of the mop 120 together, and then applying an adhesive layer to the inner surface of the mop 120 or sewing it together, a cylindrical shape can be formed to obtain the mop 120. This effectively reduces the manufacturing difficulty and the length of the slit 121, thereby reducing the contact length between the scraper and the slit 121.

[0036] In some implementations, such as Figure 3As shown, the mop 120 includes an arc surface 1253 and a first surface 1251 and a second surface 1252 that are opposite to each other. The arc surface 1253 connects the first surface 1251 and the second surface 1252. A first edge 1211 is located on the first surface 1251, and a second edge 1212 is located on the second surface 1252. A gap 121 is continuously located on the first surface 1251, the arc surface 1253, and the second surface 1252. The portion of the gap 121 located on the arc surface 1253 is spirally arranged, and the portions of the gap 121 located on the first surface 1251 and the second surface 1252 can be arc-shaped gaps, multi-segment zigzag gaps, or straight lines, etc. This method simply requires setting the edges of both ends of the mop 120 to be interlocking curved edges. By enclosing the strip mop 120 and bringing the edges of the two ends of the mop 120 together, a roughly spiral-shaped first gap 1213 and a second gap 1214 can be formed. Then, by applying an adhesive layer to the inner surface of the mop 120 or by sewing it together, a cylindrical shape can be formed, effectively reducing manufacturing difficulty and shortening the length of the gap 121, thus reducing the contact length between the scraper and the gap 121. Furthermore, the gap 121 can be continuously located between the first surface 1251 and the curved surface 1253, or between the second surface 1252 and the curved surface 1253, depending on actual needs.

[0037] In some implementations, such as Figure 5 As shown, the first part of the slit 121, slit 1215, can extend in a direction parallel to the rotation axis X. The second part of the slit 121, slit 1216, is spirally arranged around the rotation axis X. The length of the second part of the slit 1216 is greater than the length of the first part of the slit 1215. The length of the first part of the slit 1215 should be as short as possible so that the scraper will not cause significant obstruction to the mop 120 when it passes through the first part of the slit 1215. For example, the length of the second part of the slit 1216 can be more than twice or more than twice the length of the first part of the slit 1215. Specifically, the first part of the gap 1215 can be provided at the first position of the first edge 1211 in a direction approximately parallel to the rotation axis X. The second part of the gap 1216 in the gap 121 extends from the end of the first part of the gap 1215 away from the first edge 1211 to the second position of the second edge 1212. The second part of the gap 1216 can be spiraled around the rotation axis X to the second position. The first position and the second position can be located on the same side or opposite sides of the plane of symmetry of the mop 120 (the plane of symmetry between the upper surface and the lower surface of the mop 120).

[0038] It should be noted that when the mop 120 is not cylindrical, for example, when it is elliptical, the shape and position of the slits 121 in the above examples will change as the mop 120 rotates. When the portion of the mop 120 with the slits 121 rotates to contact the roller, the surface of that portion deforms into an arc surface. Therefore, at least a portion of the slits 121 located at that portion generally presents a spiral structure around the rotation axis X. Thus, the shape of the slits 121 in the above examples may actually change depending on the shape of the mop 120, but when the mop 120 rotates to a specific position, at least a portion of the slits 121 will present the spiral shape described in the above examples. It should be noted that the width of the slits 121 shown in the various figures is not the actual width of the slits 121. The width of the slits 121 can be uniformly or non-uniformly set, and the width of the slits 121 is less than the thickness of the scraper. For example, the width of the slits 121 can be within 1 to 6 mm.

[0039] Furthermore, in some embodiments, the number of mop pads 120 can be two or more. Two mop pads 120 can be arranged around the outer periphery of the rotating component 110, and at least two mop pads 120 can be arranged around the outer periphery of the rotating component 110, forming a splicing gap (not shown) between the at least two mop pads 120. The splicing gap is spirally arranged around the outer periphery of the rotating component 110. The splicing gap can spiral from a third position of the first edge 1211 of the mop pad 120 to a fourth position of the second edge 1212 of the mop pad 120. The third position and the fourth position can be located simultaneously on the upper or lower surface of the mop pad 120. For example, the third position and the fourth position can be located simultaneously on the first surface 1251 or the second surface 1252, or the third position and the fourth position can be located on the first surface 1251 and the arc surface 1253, respectively, or the third position and the fourth position can be located on the second surface 1252 and the arc surface 1253, respectively.

[0040] In some implementations, such as Figure 6As shown, the inner surface of the mop 120 is provided with a transmission layer 130. The transmission layer 130 can be formed on the inner surface of the mop 120 by coating or bonding. When the mop 120 is fitted onto the outer periphery of the rotating assembly 110, the transmission layer 130 is located between the rotating assembly 110 and the mop 120. The transmission layer 130 is in transmission engagement with the rotating assembly 110. The transmission layer 130 can play an anti-slip role, preventing the mop 120 from slipping relative to the rotating assembly 110, which is beneficial to the transmission between the rotating assembly 110 and the mop 120. The transmission layer 130 can be a flexible structure, such as a silicone layer or an elastic rubber layer, which can give the mop 120 a certain cushioning effect. When the mop mechanism 100 comes into contact with the surface to be cleaned, the transmission layer 130 can deform to a certain extent to appropriately squeeze the ground, thereby enhancing the cleaning power of the mop mechanism 100. Furthermore, when the scraper comes into contact with the mop 120, the transmission layer 130 can provide cushioning to further reduce the possibility of interference between the scraper and the mop 120. The transmission layer 130 can be a one-piece molded structure, such as a cylindrical silicone layer or an elastic rubber layer. The transmission layer 130 is formed on the inner surface of the mop 120 by adhesive bonding. Alternatively, the transmission layer 130 can be formed on the inner surface of the mop 120 by coating. For example, silicone can be coated on the inner surface of the mop 120, and after the silicone cures, it is molded into a cylindrical structure.

[0041] In some embodiments, the transmission layer 130 is sewn to the edge of the mop portion 125, that is, the transmission layer 130 and the edge of the mop portion 125 are sewn together with needle and thread to further improve the connection strength between the transmission layer 130 and the edge of the mop portion 125 and avoid the problem that the edge of the mop 120 and the transmission layer 130 are prone to separation.

[0042] By arranging at least a portion of the gap in the mop mechanism in a spiral configuration, the entire scraper blade will not simultaneously abut against the edge of the mop at the gap when scraping the mop. This reduces the area of ​​the entire scraper blade in contact with the gap at the same time, greatly reducing the interference between the scraper blade and the edge of the mop at the gap. As the mop rotates relative to the scraper blade, it rotates more smoothly. Because the scraper blade intersects with the gap, it can pass smoothly through the gap without getting stuck. This avoids problems such as the scraper blade jamming the mop, which could lead to unstable motor drive current, motor stalling, or motor overheating and burnout.

[0043] Please see Figure 7 and Figure 8This application provides an intelligent cleaning device 300, which can be a robotic vacuum cleaner or a wall cleaning robot. The cleaning device 300 includes a movable chassis 320, a scraping assembly 310, and the aforementioned mop mechanism 100. The mop mechanism 100 is disposed at the bottom of the movable chassis 320. The scraping assembly 310 includes a scraper 311, which is arranged along the rotation axis X of the mop mechanism 100 and abuts against the mop 120. The mop mechanism 100 is detachably disposed at the bottom of the movable chassis for easy replacement and cleaning. Furthermore, the scraping assembly 310 may also include a wastewater box 312 for collecting wastewater scraped off the mop mechanism 100 by the scraper 311.

[0044] In some embodiments, the intelligent cleaning device may further include a water outlet assembly (not shown) with its outlet facing the mop mechanism 100 and / or the surface to be cleaned, to apply clean water to the mop mechanism 100 and / or the surface to be cleaned. Exemplarily, the outlet includes a first outlet and a second outlet, wherein the first outlet faces the surface to be cleaned and the second outlet faces the mop mechanism 100. Alternatively, only the first outlet or the second outlet may be provided. This allows the cleaning device to keep the mop mechanism 100 moist during the cleaning process for mopping the surface to be cleaned.

[0045] The intelligent cleaning device provided in this application embodiment, by setting the mop mechanism 100 as described above, and by arranging at least a portion of the gaps in the mop in the mop mechanism in a spiral manner, ensures that when the scraper blade performs scraping operations on the mop, the entire scraper blade will not simultaneously abut against the edge of the mop located in the gap, reducing the area of ​​the entire scraper blade in contact with the gap at the same time. Each time, a smaller portion of the scraper blade contacts the gap simultaneously, further reducing the contact area of ​​the entire scraper blade with the gap, greatly reducing the amount of interference between the scraper blade and the edge of the mop located in the gap. Thus, the mop rotates more smoothly during the rotation of the mop relative to the scraper blade. Since the scraper blade intersects with the gap, it can pass through the gap smoothly without getting stuck in the gap, avoiding problems such as the scraper blade jamming the mop, causing unstable drive current of the motor, resulting in motor stalling or motor overheating and burning out.

[0046] Please see Figure 9This application also provides a handheld cleaning device 400, which includes a handheld component 410, a scraping assembly 310, and the aforementioned mop mechanism 100. The handheld component 410 includes a handheld part 411 and a mounting part 412 connected together. A rotating assembly 110 is rotatably connected to the mounting part 412. The scraping assembly 310 includes a scraper 311, which is arranged in a preset direction and abuts against the mop 120. The preset direction is substantially consistent with the rotation axis X of the mop mechanism 100. The user can operate the cleaning device 400 by hand to clean the surface to be cleaned. In addition, the scraping assembly 310 may also include a wastewater box 312 for collecting wastewater scraped off the mop mechanism 100 by the scraper 311.

[0047] In some embodiments, the handheld cleaning device 400 may also include a water outlet assembly (not shown) with its outlet facing the mop mechanism 100 and / or the surface to be cleaned, to apply clean water to at least one of the mop mechanism 100 and the surface to be cleaned. A first outlet in the water outlet assembly faces the mop mechanism 100 and a second outlet faces the surface to be cleaned, so that the cleaning device 400 can keep the mop mechanism 100 moist during the cleaning process to mop the surface to be cleaned.

[0048] The handheld cleaning device 400 provided in this application embodiment, by setting the mop mechanism 100 as described above, and by setting at least a portion of the gap of the mop in the mop mechanism in a spiral arrangement, ensures that when the scraper is scraping the mop, the entire scraper will not simultaneously abut against the edge of the mop located in the gap, reducing the area of ​​the entire scraper in contact with the gap at the same time. Each time, a smaller portion of the scraper contacts the gap simultaneously, greatly reducing the amount of interference between the scraper and the edge of the mop located in the gap. Thus, the mop rotates more smoothly during the rotation of the mop relative to the scraper. Since the scraper intersects with the gap, the scraper can pass through the gap smoothly without getting stuck in the gap, avoiding problems such as the scraper jamming the mop, causing unstable drive current of the motor, resulting in motor stalling or overheating and burning out of the motor.
