Description

Technical Field

[0001] This application relates to the field of cleaning technology, and in particular to a scraper, brush head and cleaning equipment. Background Technology

[0002] For related technologies, please refer to Figure 1 The scraper 10 includes a connecting part 11 and a scraping part 12 connected to the connecting part 11. The scraper 10 is fixed to the brush head body of the brush head through the connecting part 11, and the scraping part 12 is used to scrape dirt on the ground. However, when the scraper moves forward with the brush head to clean the ground, if there is dirt left behind the scraping part, it cannot be sucked up, and the direction of the brush head must be manually adjusted, resulting in a poor user experience. Utility Model Content

[0003] In view of this, embodiments of this application provide a scraper, a brush head, and a cleaning device to solve the problem that dirt left behind the scraper cannot be sucked away.

[0004] The first aspect of this application proposes a scraper, comprising:

[0005] The connecting part is used to fix the brush head body to the brush head.

[0006] A scraping part is connected to the connecting part. The scraping part includes at least two scraping elements arranged at intervals along a first direction. A suction channel is formed between two adjacent scraping elements. The suction channel communicates with both sides of the scraping part in a second direction.

[0007] Wherein, the first direction is perpendicular to the second direction.

[0008] The beneficial effects of the squeegee provided in this application embodiment are as follows: The squeegee of this application includes a connecting part and a scraping part connected to the connecting part. The squeegee is fixedly connected to the brush head body of the brush head through the connecting part. When the squeegee moves forward with the brush head to clean the ground, the scraping part can scrape away most of the dirt on the ground. The brush head can also suck away the dirt left behind the scraping part through the suction channel, eliminating the need for manual adjustment of the brush head's running direction and improving the user experience.

[0009] In some embodiments, the projections of two adjacent scraping elements in the second direction are continuous.

[0010] In some embodiments, the projection portions of two adjacent scrapers in the second direction overlap, and the overlapping portions form the suction channel.

[0011] The beneficial effects of adopting the above technical solution are as follows: the projection of all scraping parts in the second direction is uninterrupted. When the scraping part moves forward with the brush head to scrape the dirt on the ground, the scraping part has the same function as the scraping part in the prior art. It can effectively scrape the dirt in front of the scraping part and make the dirt sucked away through the suction port. Moreover, the brush head can also suck away the dirt missed behind the scraping part through the suction channel, without the need to manually adjust the running direction of the brush head, thus improving the user experience.

[0012] In some embodiments, at least three scraping elements are arranged at intervals along the first direction, one of which is an intermediate scraping element; in the first direction, the scraping element located on a first side of the intermediate scraping element is a first scraping element, and the scraping element located on a second side of the intermediate scraping element is a second scraping element, wherein the first scraping element and the second scraping element have opposite inclination directions.

[0013] The beneficial effects of adopting the above technical solution are as follows: Since the first scraper and the second scraper are located on both sides of the middle scraper in the first direction X, and the first scraper and the second scraper are tilted in opposite directions, the first scraper and the second scraper can be symmetrically arranged on both sides of the middle scraper, which is beneficial to the arrangement of the first scraper and the second scraper, and at the same time can improve the aesthetics.

[0014] In some embodiments, the suction channel formed between two adjacent first scraping members faces the suction port of the brush head, and / or, the suction channel formed between two adjacent second scraping members faces the suction port of the brush head.

[0015] The beneficial effects of adopting the above technical solution are: by orienting the suction channel toward the suction port, it is beneficial for dirt behind the scraper to enter the suction port through the suction channel, thereby improving the cleaning efficiency of dirt.

[0016] In some embodiments, the intermediate scraper is located at the middle position of the scraping portion in the first direction, and in the running direction of the brush head, the front end of the first scraper is closer to the intermediate scraper than its rear end, and the front end of the second scraper is closer to the intermediate scraper than its rear end.

[0017] The beneficial effects of adopting the above technical solution are as follows: the suction port is usually located in the middle of the brush head body in the first direction, and the middle scraping component is set in the middle of the scraping part; in this way, multiple first scraping components and multiple second scraping components can be symmetrically arranged on both sides of the middle scraping component, which is beneficial to the arrangement of the first scraping component and the second scraping component, and at the same time can improve the aesthetics.

[0018] In some embodiments, the intermediate scraper is a straight line extending along the first direction; or, the intermediate scraper is an inverted V-shape or inverted U-shape that opens rearward in the running direction of the brush head.

[0019] The beneficial effects of adopting the above technical solution are: by designing the intermediate scraper as a straight line, the structure of the intermediate scraper is relatively simple and easy to process and form.

[0020] In some embodiments, the scraping element is a scraping blade.

[0021] In some embodiments, the connecting portion is fixedly connected to the brush head body by a threaded fastener, and the connecting portion is provided with a countersunk hole through which the threaded fastener passes.

[0022] The beneficial effects of adopting the above technical solution are as follows: the connecting part is fixedly connected to the brush head body by threaded fasteners, which can ensure the reliability of the scraper; and the head of the threaded fastener can be recessed into the countersunk hole, improving the aesthetics.

[0023] In some embodiments, the connecting portion and the scraping portion are injection molded in two colors.

[0024] The advantages of adopting the above technical solution are: two-color injection molding has higher production efficiency, which is conducive to the mass production of products.

[0025] A second aspect of this application provides a brush head comprising a brush head body and a scraper as described in the first aspect, the scraper being fixedly connected to the brush head body.

[0026] The brush head adopts any one or more embodiments of the above-described scraper, and therefore has the beneficial effects of the above-described embodiments, which will not be described in detail here.

[0027] A third aspect of this application provides a cleaning device comprising a brush head as described in the second aspect.

[0028] The cleaning device employs any one or more embodiments of the brush head described above, and thus has the beneficial effects of the embodiments described above, which will not be elaborated further here.

[0055] For related technologies, please refer to Figure 1 The scraper 10 includes a connecting part 11 and a scraping part 12. The scraping part 12 is used to scrape dirt on the ground. The scraper 10 is fixed to the brush head body of the brush head through the connecting part 11. When the scraper 10 moves forward with the brush head to clean the ground, if there is dirt behind the scraping part 12, it cannot be sucked up. The brush head's running direction must be manually adjusted, resulting in a poor user experience.

[0056] To address the aforementioned technical problems, this application proposes a scraper, a brush head, and a cleaning device.

[0057] The first aspect of this application provides a scraper. Please refer to... Figure 3 and Figure 4 The scraper 10 can be applied to the brush head 100. In the running direction of the brush head 100, the scraper 10 is located behind the roller brush 20. After the roller brush 20 cleans the ground, the scraper 10 closely cooperates with the ground to scrape off the dirt (such as garbage and water) remaining on the ground. At the same time, the dirt is sucked away through the suction port 30 of the brush head 100.

[0058] Please refer to Figure 2 and Figure 3 The scraper 10 includes a connecting portion 11 and a scraping portion 12. The connecting portion 11 is used for fixed connection with the brush head body 40 of the brush head 100; the scraping portion 12 is connected to the connecting portion 11, and the scraping portion 12 includes at least two scraping elements 121 arranged at intervals along a first direction X. A suction channel 122 is formed between two adjacent scraping elements 121, and the suction channel 122 communicates with both sides of the scraping portion 12 in a second direction Y. Wherein, the first direction X is perpendicular to the second direction Y.

[0059] The connecting part 11 is used for fixed connection to the brush head body 40. Understandably, the connecting part 11 is made of a rigid material, for example, the connecting part 11 can be made of rigid plastic. The connecting part 11 can be fixedly connected to the bottom of the brush head body 40 by means of fastener connection, snap-fit, adhesive or other methods.

[0060] The scraper part 12 is used to scrape off dirt residue on the ground. Understandably, the scraper part 12 is made of a soft material, such as rubber or soft, wear-resistant plastic.

[0061] The scraping part 12 is connected to the connecting part 11. It can be understood that the scraping part 12 and the connecting part 11 can be integrally injection molded, i.e., the scraping part 12 and the connecting part 11 are integrally connected. For example, the scraping part 12 and the connecting part 11 can be two-color injection molded, or the scraping part 12 and the connecting part 11 can also be two-stage injection molded. Of course, the scraping part 12 can also be fixedly connected to the connecting part 11 by means of bonding, snap-fitting, fastener connection, etc.

[0062] It is understood that the scraping components 121 can be arranged in two, three, four, or more intervals along the first direction X. That is, when N (N is an integer and greater than 1) scraping components 121 are arranged at intervals along the first direction X, the corresponding number of suction channels 122 is N-1. For example, when two scraping components 121 are arranged at intervals along the first direction X, the corresponding number of suction channels 122 is one; when three scraping components 121 are arranged at intervals along the first direction X, the corresponding number of suction channels 122 is two; and when four scraping components 121 are arranged at intervals along the first direction X, the corresponding number of suction channels 122 is three.

[0063] A suction channel 122 is formed between two adjacent scraping parts 121. The suction channel 122 connects both sides of the scraping part 12 in the second direction Y, that is, under suction, as... Figure 2 As indicated by the arrow at the suction channel 122, dirt on the side of the scraper 121 facing the connecting part 11 can be sucked through the suction channel 122 to the side of the scraper 121 facing away from the connecting part 11.

[0064] It can be understood that the first direction X is perpendicular to the second direction Y, but this is not limited to the strict sense of perpendicularity; that is, the first direction X can also be approximately perpendicular to the second direction Y.

[0065] Please refer to Figure 3 When the scraper 10 is mounted on the brush head body 40, the second direction Y is the operating direction of the brush head 100, that is, the second direction Y can be understood as the front-to-back direction, for example, the arrow of the second direction Y points backward; the first direction X is the axial direction of the roller brush 20, that is, the first direction X can be understood as the left-to-right direction, for example, the arrow of the first direction X points to the left. The dirt on the rear side of the scraper 121 can be sucked to the front side of the scraper 121 through the suction channel 122.

[0066] The beneficial effects of the scraper 10 provided in this application embodiment are as follows: The scraper 10 of this application includes a connecting part 11 and a scraping part 12 connected to the connecting part 11. The scraper 10 is fixedly connected to the brush head body 40 of the brush head 100 through the connecting part 11. When the scraper 10 moves forward with the brush head 100 to clean the ground, the scraping part 12 can scrape away most of the dirt on the ground. The brush head 100 can also suck away the dirt left behind the scraping part 12 through the suction channel 122, without the need for manual adjustment of the running direction of the brush head 100, thus improving the user experience.

[0067] In some embodiments, the projections of two adjacent scraping elements 121 in the second direction Y are continuous. That is, the projections of two adjacent scraping elements 121 in the second direction Y have no breaks.

[0068] For example, please refer to Figure 2 The projection portions of two adjacent scraping parts 121 overlap in the second direction Y, and a suction channel 122 is formed between the overlapping portions.

[0069] This can be understood as the formation of a suction channel 122 between the closest ends of two adjacent scraping parts 121. Figure 2 Taking the two leftmost scraping parts 121 as an example, the right end of the left scraping part 121 and the left end of the right scraping part 121 are spaced apart in the second direction Y to form a suction channel 122.

[0070] For example, the projection portions of any two adjacent scraping elements 121 in the second direction Y overlap, which can be understood as the projections of all scraping elements 121 in the second direction Y having no breaks.

[0071] Based on the above technical solution, when the scraping part 12 moves forward with the brush head 100 to scrape the dirt on the ground, it can effectively scrape the dirt in front of the scraping part 12 and make the dirt sucked away through the suction port 30; moreover, the brush head 100 can also suck away the dirt left behind by the scraping part 12 through the suction channel 122, without the need to manually adjust the running direction of the brush head 100, thus improving the user experience.

[0072] Please refer to Figure 2 In some embodiments, at least three scraping members 121 are arranged at intervals along a first direction X, one of which is a middle scraping member 1211; in the first direction X, the scraping member 121 located on the first side of the middle scraping member 1211 is the first scraping member 1212, and the scraping member 121 located on the second side of the middle scraping member 1211 is the second scraping member 1213, and the first scraping member 1212 and the second scraping member 1213 have opposite inclination directions.

[0073] It should be noted that the intermediate scraping member 1211 refers to the fact that it is located between the first scraping member 1212 and the second scraping member 1213, and does not mean that the intermediate scraping member 1211 is necessarily located in the middle of the scraping part 12; that is, in the first direction X, the intermediate scraping member 1211 may or may not be located in the middle of the scraping part 12.

[0074] It is understood that the number of the first scratching component 1212 can be one or more; the number of the second scratching component 1213 can also be one or more. Among them, the number of the first scratching component 1212 can be the same as the number of the second scratching component 1213, or the number of the first scratching component 1212 can be different from the number of the second scratching component 1213.

[0075] The first scraper 1212 and the second scraper 1213 are tilted in opposite directions. Understandably, the tilt angles of the first scraper 1212 and the second scraper 1213 can be the same or different.

[0076] For example, the angle between the first scraping member 1212 and the first direction X is greater than 0° and less than 90°. For example, the angle between the first scraping member 1212 and the first direction X is 10°, 20°, 30°, 40°, 45°, 50°, 60° or 70°, etc.; wherein, the angle between the second scraping member 1213 and the first direction X is 0-90°. For example, the angle between the second scraping member 1213 and the first direction X is 10°, 20°, 30°, 40°, 45°, 50°, 60° or 70°, etc.

[0077] When the first scraper 1212 and the second scraper 1213 have the same tilt angle and number, and the intermediate scraper 1211 is located in the middle of the scraping section 12, the first scraper 1212 and the second scraper 1213 are symmetrically arranged on both sides of the intermediate scraper 1211. This arrangement is beneficial for the arrangement of the first scraper 1212 and the second scraper 1213, and also improves aesthetics. This arrangement is suitable when the suction port 30 is located in the middle of the brush head body 40 in the first direction X.

[0078] In other embodiments, the intermediate scraper 1211 may be omitted, and the first scraper 1212 and the second scraper 1213 may have the same inclination direction; exemplaryly, all the first scrapers 1212 and all the second scrapers 1213 may be arranged in parallel. This arrangement is suitable when the suction port 30 is located near the edge of the brush head body 40 in the first direction X.

[0079] It should be noted that if the intermediate scraper 1211, the first scraper 1212 and the second scraper 1213 are a combined unit, the combined unit can be one or more.

[0080] Please refer to Figure 2 and Figure 4 In some embodiments, the suction channel 122 formed between two adjacent first scraping members 1212 faces the suction port 30 of the brush head 100, and the suction channel 122 formed between two adjacent second scraping members 1213 faces the suction port 30 of the brush head 100.

[0081] The waste flows from the suction channel 122 to the suction port 30, and the flow direction of the waste within the suction channel 122 is as follows: Figure 2 The direction indicated by the arrow inside the central suction channel 122 Figure 2 The arrow in the image points towards the suction port 30 of the brush head 100, meaning that the suction channel 122 points towards the suction port 30 of the brush head 100.

[0082] For example, the suction channel 122 formed between any two adjacent first scraping members 1212 faces the suction port 30 of the brush head 100, and the suction channel 122 formed between any two adjacent second scraping members 1213 faces the suction port 30 of the brush head 100.

[0083] Understandably, when the suction port 30 is in the middle position of the brush head body 40, the first scraper 1212 and the second scraper 1213 are tilted in opposite directions, but the tilt angles can be the same.

[0084] Based on the above technical solution, by orienting the suction channel 122 toward the suction port 30, it is beneficial for the dirt behind the scraper 121 to enter the suction port 30 through the suction channel 122, thereby improving the cleaning efficiency of the dirt.

[0085] In other embodiments, the suction channel 122 formed between two adjacent first scraping members 1212 faces the suction port 30 of the brush head 100, and the suction channel 122 formed between two adjacent second scraping members 1213 faces the side of the suction port 30 of the brush head 100; or, the suction channel 122 formed between two adjacent first scraping members 1212 faces the side of the suction port 30 of the brush head 100, and the suction channel 122 formed between two adjacent second scraping members 1213 faces the suction port 30 of the brush head 100; or, the suction channel 122 formed between two adjacent first scraping members 1212 faces the side of the suction port 30 of the brush head 100, and the suction channel 122 formed between two adjacent second scraping members 1213 faces the side of the suction port 30 of the brush head 100.

[0086] Please refer to Figure 2In some embodiments, the intermediate scraper 1211 is a straight line extending along the first direction X.

[0087] The intermediate scraper 1211 is located behind the adjacent first scraper 1212 and second scraper 1213. It is understood that a suction channel 122 is formed between the first end of the intermediate scraper 1211 and the first scraper 1212, and a suction channel 122 is also formed between the second end of the intermediate scraper 1211 and the second scraper 1213; exemplaryly, both suction channels 122 face the suction port 30.

[0088] Based on the above technical solution, by designing the intermediate scraper 1211 as a straight line, the structure of the intermediate scraper 1211 is relatively simple and easy to process and form.

[0089] Of course, the intermediate scraping member 1211 can also be an inverted V-shape or inverted U-shape with an opening facing backward in the running direction of the brush head 100, that is, the opening of the inverted V-shape or inverted U-shape intermediate scraping member 1211 is aligned with the arrow direction of the second direction Y.

[0090] Please refer to Figures 2 to 4 In some embodiments, in the first direction X, the intermediate scraper 1211 is located in the middle position of the scraper portion 12.

[0091] Typically, the suction port 30 is located in the middle of the brush head body 40 in the first direction X. By setting the middle scraper 1211 in the middle of the scraping part 12, multiple first scrapers 1212 and multiple second scrapers 1213 can be symmetrically arranged on both sides of the middle scraper 1211, which is beneficial to the arrangement of the first scrapers 1212 and the second scrapers 1213, and can also improve the aesthetics.

[0092] Specifically, when the suction channel 122 formed between two adjacent first scraping members 1212 faces the suction port 30 of the brush head 100, and when the suction channel 122 formed between two adjacent second scraping members 1213 faces the suction port 30 of the brush head 100, it can be understood that, in the running direction of the brush head 100, the front end of the first scraping member 1212 is closer to the middle scraping member 1211 than its rear end, and the front end of the second scraping member 1213 is closer to the middle scraping member 1211 than its rear end. Specifically, the front end of the first scraping member 1212 is the end of the first scraping member 1212 closest to the roller brush 20, and the rear end of the first scraping member 1212 is the end of the first scraping member 1212 furthest from the roller brush 20; similarly, the front end of the second scraping member 1213 is the end of the second scraping member 1213 closest to the roller brush 20, and the rear end of the second scraping member 1213 furthest from the roller brush 20.

[0093] In other embodiments, in the first direction X, the intermediate scraper 1211 may also be arranged offset from the suction port 30 of the brush head 100.

[0094] Please refer to Figure 2 In some embodiments, the scraper 121 is a scraper blade.

[0095] For example, the scraper blades are rectangular. All scraper blades have the same width to ensure consistent contact with the ground; however, the lengths of all scraper blades can be the same or different.

[0096] For example, the first scraper 1212 is a first scraper blade, and all the first scraper blades are arranged in parallel; the second scraper 1213 is a second scraper blade, and all the second scraper blades are arranged in parallel.

[0097] Please refer to Figure 2 In some embodiments, the connecting part 11 is fixedly connected to the brush head body 40 by a threaded fastener, and the connecting part 11 is provided with a countersunk hole 111 for the threaded fastener to pass through.

[0098] Understandably, the brush head body 40 is provided with a threaded hole. By passing a threaded fastener through the countersunk hole 111 and screwing it into the threaded hole, the connecting part 11 is fixedly connected to the brush head body 40. The threaded fastener can be a screw, bolt, etc.

[0099] To ensure the stability of the fixed connection of the scraper 10, the number of countersunk holes 111 on the connecting part 11 is multiple, for example, two, three, four or more. Exemplarily, the multiple countersunk holes 111 are arranged at intervals along the first direction X. The number of threaded fasteners is multiple, and the number of threaded fasteners is less than or equal to the number of countersunk holes 111.

[0100] Based on the above technical solution, the connecting part 11 is fixedly connected to the brush head body 40 by a threaded fastener, which can ensure the reliability of the scraper 10; and the head of the threaded fastener can be recessed into the countersunk hole 111 to improve the aesthetics.

[0101] In other embodiments, the connecting part 11 can be fixedly connected to the brush head body 40 by means of snap-fit, adhesive or other methods.

[0102] Please refer to Figure 3 and Figure 4 The second aspect of this application provides a brush head 100. The brush head 100 includes a brush head body 40 and a scraper 10 as described in the first aspect, the scraper 10 being fixedly connected to the brush head body 40.

[0103] The brush head 100 also includes a roller brush 20. In the direction of operation of the brush head 100, the scraper 10 is located behind the roller brush 20. After the roller brush 20 cleans the floor, the scraper 10 closely cooperates with the floor to scrape off the dirt remaining on the floor. At the same time, the dirt is sucked away through the suction port 30 of the brush head 100.

[0104] For example, the length of the scraper 10 in the first direction X is greater than the axial length of the roller brush 20 to ensure cleaning effect. Of course, the length of the scraper 10 in the first direction X can also be equal to the axial length of the roller brush 20.

[0105] The beneficial effects of the brush head 100 provided in this application embodiment are as follows: The brush head 100 of this application includes a scraper 10. When the scraper 10 moves forward with the brush head 100 to clean the ground, the scraping part 12 of the scraper 10 can scrape away most of the dirt on the ground. If there is any dirt left behind the scraping part 12, the brush head 100 can suck away the dirt left behind the scraping part 12 through the suction channel 122 of the scraper 10, without the need for manual adjustment of the running direction of the brush head 100, thus improving the user experience.

[0106] Please refer to Figure 5 A third aspect of this application discloses a cleaning device 1000. The cleaning device 1000 includes a brush head 100 as described in the second aspect.

[0107] The cleaning equipment 1000 can be a floor scrubber. For example, the cleaning equipment 1000 is a handheld floor scrubber, meaning that the cleaning equipment 1000 also includes a body 200 and a handle 300, with the body 200 located between the brush head 100 and the handle 300; the body 200 is equipped with a clean water tank and a wastewater tank. During operation, the brush head 100 is operated by manipulating the handle 300 to clean the floor.

[0108] The cleaning device 1000 employs any one or more embodiments of the brush head 100 described above, and thus has the beneficial effects of the embodiments described above, which will not be elaborated further here.
