DETAILED DESCRIPTION

[0050] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments.

[0051] Embodiment: The floor scrubber of the present invention is as follows: Figures 1 to 8 As shown in the structure, the floor scrubber mainly achieves a cleaning effect on the ground, wherein different cleaning effects on the ground are mainly achieved by the mutual replacement between the first cleaning cylinder 2 and the second cleaning cylinder 3. At the same time, the scraping member 6 structure is set to realize that a single scraping member 6 can independently scrape off the dirty liquid and dirt on the first cleaning cylinder 2 and the second cleaning cylinder 3, which is beneficial to improve the cleaning effect of the first cleaning cylinder 2 and the second cleaning cylinder 3, reduce secondary pollution to the ground, and improve the overall cleaning effect of the ground.

[0052] The present invention provides a floor scrubber, comprising a machine body 1, which moves on the ground to achieve a cleaning effect on the ground, wherein a accommodating chamber 101 is provided on the machine body 1, and the accommodating chamber 101 is a structure with an open lower position, and the floor scrubber further comprises a first cleaning barrel 2 and a second cleaning barrel 3, both of which are configured to be cylindrical structures, and the first cleaning barrel 2 and the second cleaning barrel 3 are configured to be interchangeably installed in the accommodating chamber 101, and the user can choose to install the first cleaning barrel 2 or the second cleaning barrel 3 in place, and set the outer diameter value of the first cleaning barrel 2 in the undeformed structure to be larger than the outer diameter value of the second cleaning barrel 3 in the undeformed structure, so that the first cleaning barrel 2 can achieve a closer contact and fit when it contacts the ground for cleaning, and the second cleaning barrel 3 can be better deformed when it contacts the ground for cleaning to form a scraping and cleaning effect, wherein, for the first cleaning barrel 2 and the second cleaning barrel 3, The floor scrubber also includes a structural part for scraping and separating dirty liquid and dirt, and a scraping member 6. The length structure of the scraping member 6 is set to extend along the axial direction of the first cleaning cylinder 2 or the second cleaning cylinder 3, and the height of the scraping member 6 is formed to extend into the accommodating chamber 101. The scraping member 6 is set to be able to form a structure that can rotate and swing in the up and down directions relative to the cross-section in the radial direction of the first cleaning cylinder 2 or the second cleaning cylinder 3. When the scraping member 6 is subjected to an external force, it can rotate and swing from top to bottom or from bottom to top. When the scraping member 6 performs a rotational swinging motion, it forms a structure that switches between a first position and a second position, that is, the scraping member 6 can be rotated and swung from the first position to the second position, or from the second position to the first position. The first position and the second position are different positions, so that the scraping member 6 can switch between the two positions.

[0053] Wherein, a cover cavity 102 is further provided on the machine body 1, and the scraping member 6 is installed on the cover cavity 102 and is constructed to extend into the accommodating cavity 101 in a convex structure. The height structure part of the scraping member 6 is the convex length extending into the accommodating cavity 101, and the scraping member 6 is convex downward or obliquely downward relative to the cavity wall of the accommodating cavity 101; wherein, the floor scrubber further includes a first cover member 4 and a second cover member 5, and the first cover member 4 and the second cover member 5 are configured to be interchangeably installed in the cover cavity 102, and the user can choose to install the first cover member 4 in the cover cavity 102 or install the second cover member 5 in the cover cavity 102 according to needs, and the first cover member 4 and the second cover member 5 are interchangeably installed in the same position, that is, the cover cavity 102. When the first cover member 4 When installed in place, the scraping member 6 is located in the first position and when the first cleaning cylinder 2 is installed in place, the scraping member 6 forms an interference structure for scraping dirty liquid from the first cleaning cylinder 2; when the second cover 5 is installed in place, the scraping member 6 is located in the second position and when the second cleaning cylinder 3 is installed in place, the scraping member 6 forms a contact and pressure structure for scraping dirt from the second cleaning cylinder 3; only one scraping member 6 is needed, and in combination with the structure of the scraping member 6 performing a rotating and swinging motion, it is possible to independently scrape dirty liquid and dirt from the first cleaning cylinder 2 and the second cleaning cylinder 3, and the overall structure is simple and low in cost, and the first cleaning cylinder 2 and the second cleaning cylinder 3 can be effectively scraped clean, thereby improving the cleaning effect on the ground and reducing secondary pollution to the ground.

[0054] Among them, when the first cover member 4 is installed in place, the scraping member 6 is located in the first position. At this time, the first cleaning cylinder 2 is installed in place accordingly. Since the scraping member 6 extends into the accommodating cavity 101 and forms a convex structure, the end position of the scraping member 6 will extend into the inner side of the outer surface of the first cleaning cylinder 2 to form a mutual interference structure. Under the interference structure and the structure of the rotation and rolling motion of the first cleaning cylinder 2, the scraping member 6 scrapes and separates the dirty liquid, i.e., sewage, on the first cleaning cylinder 2, thereby keeping the first cleaning cylinder 2 in a clean state and achieving the effect of collecting the dirty liquid.

[0055] Among them, when the second cover 5 is installed in place, the scraper 6 is located in the second position. At this time, the second cleaning cylinder 3 is installed in place accordingly. Since the scraper 6 extends into the accommodating cavity 101 and has a convex structure, the end position of the scraper 6 will contact the outer surface of the second cleaning cylinder 3 to form a contact and pressure structure. Under the contact and pressure structure and the structure of the second cleaning cylinder 3 rotating and rolling motion, the scraper 6 scrapes and separates the dirt and garbage on the second cleaning cylinder 3, thereby keeping the second cleaning cylinder 3 in a clean state and achieving the effect of collecting dirt.

[0056] It can be understood that the first cleaning cylinder 2 and the first cover 4 correspond to a group, and the second cleaning cylinder 3 and the second cover 5 correspond to a group. The user can choose one of the groups to install in place according to needs to meet the user's different cleaning needs for the floor.

[0057] In this solution, the first cover member 4 and the second cover member 5 can be interchanged to achieve the rotational swinging motion of the scraping member 6, so that the scraping member 6 itself does not need to be provided with a power source, the overall structure is simple, the cost is low, and the scraping member 6 has good stability in the rotational swinging motion.

[0058] In this solution, a snap-fitting portion can be provided on the machine body 1 to realize a snap-fitting and limiting structure for the first cover 4 or the second cover 5. The user can manually install the first cover 4 or the second cover 5 in place to form a snap connection on the machine body 1, thereby realizing an installation and fixing structure for the first cover 4 or the second cover 5. The user can also manually remove the first cover 4 or the second cover 5 to realize a detachable structure of the first cover 4 and the second cover 5, and realize the mutual replacement and installation of the first cover 4 and the second cover 5.

[0059] In the specific structural part, a first pressing portion 601 and a second pressing portion 602 are provided on the scraper 6, and the first pressing portion 601 and the second pressing portion 602 are located at different positions. The first pressing portion 601 and the second pressing portion 602 are mainly located at different positions on the scraper 6 in the rotational rolling direction, wherein a first contact pressing portion 401 for contacting and pressing the first pressing portion 601 is provided on the first cover 4, and a second contact pressing portion 501 for contacting and pressing the second pressing portion 602 is provided on the second cover 5; that is, the first contact pressing portion 401 and the first pressing portion 601 correspond to a group, and the second contact pressing portion 501 and the second pressing portion 602 correspond to a group. When the first cover 4 is installed in place and when the scraper 6 is in the first position, the first contact pressing portion 401 is formed into a structure that is in contact and pressing with the first pressing portion 601. At this time, the first cover 4 comes through the first contact pressing portion 4 01 comes into contact with the first pressing portion 601 and forms a contact pressing structure, thereby realizing that the scraping member 6 is pressed and limited to be fixed in the first position. The scraping member 6 is in the first position and can be used to scrape the dirty liquid from the first cleaning cylinder 2; when the second cover 5 is installed in place and when the scraping member 6 is in the second position, the second contact and pressure portion 501 forms a structure that is in contact and pressed with the second pressing portion 602. At this time, the second cover 5 comes into contact with the second pressing portion 602 through the second contact and pressure portion 501 and forms a contact pressing structure, thereby realizing that the scraping member 6 is pressed and limited to be fixed in the second position. The scraping member 6 is in the second position and can be used to scrape the dirty liquid from the second cleaning cylinder 3; in the above structure, the rotation and swinging movement of the scraping member 6 is realized during the installation of the first cover 4 or the second cover 5, so that it is located in the first position or the second position, and the effect of switching between the first position and the second position is realized.

[0060] In the present solution, for the structural part of the scraping member 6 that performs the rotational and swinging motion, when the first cover member 4 is installed in place, the first contact and pressure portion 401 is formed to apply pressure to the first crimping portion 601, so that the scraping member 6 performs the rotational and swinging motion to the first position and is fixed in place. When the user manually installs the first cover member 4 into the cover cavity 102, the first contact and pressure portion 401 contacts the first crimping portion 601 and forms an external force. Under the action of the external force, the scraping member 6 is subjected to the rotational and swinging force to rotate and swing, and is rotated and swung from the second position to the first position. When the scraping member 6 is in the first position, the first contact and pressure portion 401 is formed to crimp and fix the first crimping portion 601 and crimp and fix the scraping member 6 in the first position, so that the scraping member 6 rotates and swings to the first position to scrape the dirty liquid from the first cleaning cylinder 2.

[0061] In this solution, for the structural part of the scraping member 6 that performs rotational and swinging motion, when the second cover member 5 is installed in place, the second contact and pressure portion 501 is formed to apply pressure to the second crimping portion 602, so that the scraping member 6 performs rotational and swinging motion to the second position and is fixed in place. When the user manually installs the second cover member 5 into the cover cavity 102, the second contact and pressure portion 501 contacts the second crimping portion 602 and forms an external force. Under the action of the external force, the scraping member 6 is subjected to the rotational and swinging force to rotate and swing, and is rotated and swung from the first position to the second position. When the scraping member 6 is in the second position, the second contact and pressure portion 501 is formed to crimp and fix the second crimping portion 602 and crimp and fix the scraping member 6 in the second position, so that the scraping member 6 rotates and swings to the second position to scrape dirt from the second cleaning cylinder 3.

[0062] Among them, the user can choose to install the first cover 4 or the second cover 5 into the cover cavity 102 according to whether the first cleaning cylinder 2 or the second cleaning cylinder 3 is installed in the accommodating cavity 101, so as to realize the corresponding installation structure to clean the floor and scrape off dirty liquid and dirt.

[0063] In this solution, for the structural part of the scraper 6, an angle A is formed between the first crimping portion 601 and the second crimping portion 602 in the direction of rotational rolling motion along the first cleaning cylinder 2 or the second cleaning cylinder 3, so that the first crimping portion 601 and the second crimping portion 602 are spaced apart in the direction of rotational rolling motion. The spaced apart structure of the first crimping portion 601 and the second crimping portion 602 in the direction of rotational rolling enables the first cover 4 and the second cover 5 to be better replaced and installed in place respectively, while achieving a better contact and crimping effect on the scraper 6, forming an independent and stable contact and crimping effect, and at the same time enabling the scraper 6 to stably perform rotational and swinging motion, so that it is not easy to interfere with the position of the scraper 6 during the mutual replacement of the first cover 4 and the second cover 5, so that the scraper 6 can be stably maintained in the first position or the second position.

[0064] Optionally, the angle A is greater than or equal to 50 degrees and less than or equal to 120 degrees.

[0065] In this solution, when the first contact and pressure portion 401 is in contact and pressure contact with the first pressure contact portion 601, the first cover member 4 and the second pressure contact portion 602 are in a non-contact structure. In this way, when the first cover member 4 is installed in place, the first contact and pressure portion 401 can be used to effectively form a contact and pressure contact structure with the scraping member 6, so that the scraping member 6 is stably maintained in the first position state, and the first cover member 4 will not contact the second pressure contact portion 602, so that the scraping member 6 will not rotate and swing, so that the scraping member 6 is stably and reliably located in the first position to form a structure for scraping the dirty liquid from the first cleaning cylinder 2. Structure: When the second contact and pressure portion 501 is formed into a structure in which the second cover 5 and the first pressing portion 601 are not in contact with each other, when the second contact and pressure portion 501 is formed into a structure in which the second pressing portion 602 is in contact and pressure contact, so that when the second cover 5 is installed in place, the scraping member 6 can be effectively kept in the second position state only by the second contact and pressure portion 501, and the second cover 5 will not contact the first pressing portion 601 so that the scraping member 6 will not rotate and swing, thereby making the scraping member 6 stably and reliably located in the second position to form a structure for scraping dirty liquid from the second cleaning cylinder 3.

[0066] In this solution, when the scraping member 6 is in contact with the second cleaning cylinder 3, a part of the outer surface of the second cleaning cylinder 3 is deformed and recessed to form a first recess 301. On the first recess 301, the outer surface of the end position of the scraping member 6 contacts the outer surface of the second cleaning cylinder 3 and forms a contact and pressure structure. As the second cleaning cylinder 3 rotates and rolls, the scraping member 6 scrapes the dirty liquid and dirt on the outer surface of the second cleaning cylinder 3. The maximum recess depth of the first recess 301 is set to be smaller than the maximum interference depth formed when the scraping member 6 is in an interference structure with the first cleaning cylinder 2. By setting the maximum interference depth of the interference structure to be relatively larger, the scraping member 6 can penetrate deep into the first cleaning cylinder 2. The inner side of the outer surface of the cleaning cylinder 2 is used to effectively squeeze the dirty liquid absorbed by the first cleaning cylinder 2, so as to better scrape off the absorbed dirty liquid in depth. By setting the maximum recessed depth of the first recessed portion 301 to be relatively smaller, the scraping member 6 can better form a relatively sliding structure on the outer surface of the second cleaning cylinder 3. At the same time, the degree of deformation of the outer surface of the second cleaning cylinder 3 is also smaller, so that the durability of the second cleaning cylinder 3 is improved. At the same time, a better rebound structure can be formed to enable the first recessed portion 301 to gradually deform from a recessed structure to an arc-shaped surface structure. The above structure not only realizes the stable rotation and rolling motion of the first cleaning cylinder 2 or the second cleaning cylinder 3 when in place, but also effectively guides the dirty liquid and dirt to be collected.

[0067] In this solution, with respect to the structure when the first cleaning cylinder 2 is installed in the accommodating chamber 101, a first gap portion is formed between the outer surface of the first cleaning cylinder 2 and the cavity wall of the accommodating chamber 101 in the radial direction of the first cleaning cylinder 2. The first gap portion prevents the outer surface of the first cleaning cylinder 2 from contacting the cavity wall of the accommodating chamber 101 during the rotational rolling motion. Instead, under the structure of the rotational rolling motion, part of the dirty liquid and dirt on the first cleaning cylinder 2 are thrown onto the cavity wall of the accommodating chamber 101, and are scraped off by the scraping member 6 at the same time. The dirty liquid separated from the first cleaning cylinder 2 can form an effective guiding reflux structure on the cavity wall of the accommodating chamber 101, thereby achieving better collection and treatment of the dirty liquid scraped off the first cleaning cylinder 2; with respect to the first cleaning cylinder 2 The second cleaning cylinder 3 is installed in the structure of the accommodating chamber 101, and a second gap portion is formed between the outer surface of the second cleaning cylinder 3 and the cavity wall of the accommodating chamber 101 in the radial direction of the second cleaning cylinder 3. The second gap portion prevents the outer surface of the second cleaning cylinder 3 from contacting the cavity wall of the accommodating chamber 101 during the rotational rolling motion. Instead, the rotational rolling motion structure forms a structure in which part of the dirty liquid and dirt on the second cleaning cylinder 3 is thrown onto the cavity wall of the accommodating chamber 101, and is scraped away by the scraping member 6 at the same time. The dirt separated from the second cleaning cylinder 3 is not easily clogged in the second gap portion, and an effective guiding and falling structure can be formed on the cavity wall of the accommodating chamber 101, thereby achieving better collection and processing of the dirt scraped off the second cleaning cylinder 3.

[0068] Among them, the gap distance formed by the first gap portion along the radial direction is set to be smaller than the gap distance formed by the second gap portion along the radial direction. By setting the gap distance of the first gap portion to be relatively small, the dirty liquid can be better guided to reflux along the cavity wall of the accommodating cavity 101 for collection. By setting the gap distance of the second gap portion to be relatively large, the dirt separated on the second cleaning cylinder 3 is not easily clogged in the second gap portion, and the dirt can be better refluxed or fallen back along the cavity wall of the accommodating cavity 101 for collection. Overall, the dirty liquid and dirt can be better collected, and the problem of clogging is not easy to occur.

[0069] In this solution, the first cleaning cylinder 2 is arranged to rotate and roll around the axis N of the accommodating chamber 101 when installed in place, and the second cleaning cylinder 3 is arranged to rotate and roll around the axis N of the accommodating chamber 101 when installed in place, so that the first cleaning cylinder 2 forms a structure that is more closely in contact with the ground than the second cleaning cylinder 3 when in contact with the ground. In the structure in which the first cleaning cylinder 2 and the second cleaning cylinder 3 are replaced with each other, the first cleaning cylinder 2 and the second cleaning cylinder 3 are both configured to rotate and roll around the axis N of the accommodating chamber 101. In combination with the external shape of the first cleaning cylinder 2 in the undeformed structure, In a structure in which the diameter value is greater than the outer diameter value of the second cleaning cylinder 3 in the undeformed structure, the first cleaning cylinder 2 can form a structure that is in closer contact with the ground when in contact with the ground, thereby achieving a cleaning effect of large-area contact and high-friction contact with the ground, and can effectively lift the first cleaning cylinder 2 to absorb the dirty liquid on the ground. At the same time, the second cleaning cylinder 3 can form a structure that scrapes the ground when in contact with the ground, thereby better accommodating the dirty liquid and dirt on the ground into the first recess 301, achieving better transfer with the rotation and rolling motion, and better collection of dirty liquid and dirt.

[0070] Among them, in this scheme, the first cleaning cylinder 2 is installed in a sleeve on the first cylinder member, the first cylinder member is provided with a rotatable and rolling rotating shaft, and is installed in the accommodating cavity 101 through the rotating shaft, so that the first cleaning cylinder 2 can rotate and roll in the accommodating cavity 101 through the rotating shaft.

[0071] Among them, in this scheme, the second cleaning cylinder 3 is installed in a sleeve on the second cylinder member, the second cylinder member is provided with a rotatable and rolling rotating shaft, and is installed in the accommodating cavity 101 through the rotating shaft, so that the second cleaning cylinder 3 can rotate and roll in the accommodating cavity 101 through the rotating shaft.

[0072] In this solution, in order to further improve the effect of collecting dirty liquid and dirt, when the scraping member 6 is in the first position, the angle B1 formed between the scraping member 6 and the horizontal plane P where the central axis of the first cleaning cylinder 2 is located is smaller than the angle B2 formed between the scraping member 6 and the horizontal plane Q where the central axis of the second cleaning cylinder 3 is located when the scraping member 6 is in the second position. This is mainly because the angle B1 formed between the side surface parallel to the convex direction formed by the scraping member 6 along the convex direction and the horizontal plane P is relatively small, so that the scraped dirty liquid can be effectively concentrated to flow back downward, thereby ensuring that the dirty liquid can be better absorbed and collected; this is mainly because the angle B2 formed between the side surface parallel to the convex direction formed by the scraping member 6 along the convex direction and the horizontal plane Q is relatively large, so that the accumulation of dirt and blockage can be prevented during the scraping process, so that the dirt can better fall back downward, thereby ensuring that the dirt can be better absorbed and collected.

[0073] Optionally, the angle B1 is set to be less than or equal to 35 degrees and greater than or equal to 25 degrees.

[0074] Optionally, the angle B2 is set to be greater than or equal to 61 degrees and less than or equal to 69 degrees.

[0075] In this solution, the first cleaning cylinder 2 is configured to have a soft and water-absorbing structure, and the second cleaning cylinder 3 is configured to have a soft, deformable and hydrophobic structure, so that when the first cleaning cylinder 2 contacts the ground for cleaning, a portion of the first cleaning cylinder 2 is deformed to contact the ground for friction cleaning and has a structure that absorbs dirty liquid, i.e., sewage; when the second cleaning cylinder 3 contacts the ground for cleaning, a portion of the second cleaning cylinder 3 is deformed to form a concave cleaning portion, which has a scraping and cleaning effect on the ground, while accommodating dirty liquid and dirt and driving them to be transferred along the rotational rolling direction, and forming a structure that does not absorb dirty liquid, i.e., sewage, that is, a hydrophobic structure.

[0076] And / or, in the present embodiment, the scraping member 6 is configured to be configured to rotate and swing around an axis M, and the axis M and the axis N are parallel to each other, and the axis M is located outside the accommodating chamber 101. The scraping member 6 is mainly installed on the machine body 1, and a swing chamber is provided on the machine body 1. A swing shaft is provided on the scraping member 6. The scraping member 6 is installed in the swing chamber through the swing shaft, so that the scraping member 6 can rotate and swing through the swing shaft. The swing chamber forms an axis M along the length direction of the scraping member 6, that is, the swing chamber forms an axis M along the rotation axis direction of the first cleaning cylinder 2 or the second cleaning cylinder 3. By setting the axis M and the axis N parallel to each other, the scraping member 6 can form a longitudinal position portion of the scraping member 6 in the longitudinal direction to form an interference structure with the axial portion of the first cleaning cylinder 2, and can form a contact and pressure structure with the axial portion of the second cleaning cylinder 3, thereby effectively scraping away dirty liquid and dirt from the entire longitudinal area along the longitudinal direction of the first cleaning cylinder 2 or the second cleaning cylinder 3.

[0077] Among them, the axis M is set to be located at the outer position of the accommodating chamber 101 so that the end position of the scraping member 6 can swing synchronously when it rotates and swings, thereby forming an interference structure with the first cleaning cylinder 2 or a contact and pressure structure with the second cleaning cylinder 3, and forming a maximum recessed depth of the first recess 301 on the second cleaning cylinder 3 is smaller than the maximum interference depth formed when the scraping member 6 forms an interference structure with the first cleaning cylinder 2, so as to better achieve the scraping of dirty liquid and dirt from the first cleaning cylinder 2 and the second cleaning cylinder 3.

[0078] The first cleaning tube 2 of this solution is mainly configured to be made of cloth material, or a flocked layer, or a sponge material, so that the first cleaning tube 2 has a soft structure and a water-absorbent structure.

[0079] The second cleaning tube 3 of this solution is mainly configured to be made of a rubber material, such as a silicone material, a rubber material or a silicone rubber material, so that the second cleaning tube 3 has a soft and deformable structure and a hydrophobic structure, and also has a certain wear-resistant structure.

[0080] In this solution, a driving member is provided on the machine body 1, and the driving member is a motor. The driving member is connected to a pulley transmission structure or a gear transmission structure to transmit driving force. The driving force drives the first cleaning cylinder 2 or the second cleaning cylinder 3 to rotate and roll to achieve a cleaning effect on the ground.

[0081] The floor scrubber of this solution can be a handheld floor scrubber or a self-propelled floor scrubber robot, both of which can achieve a good cleaning effect on the floor.

[0082] Anything not mentioned in this plan can be achieved by adopting or drawing on existing technologies.

[0083] Working principle: The floor scrubber of this scheme is provided with a first cleaning cylinder 2, a second cleaning cylinder 3, a scraping member 6, a first cover member 4 and a second cover member 5. The first cleaning cylinder 2 and the first cover member 4 are used as a group, and the second cleaning cylinder 3 and the second cover member 5 are used as a group. The scraping member 6 is provided with a structure that can rotate and swing, so that when the first cleaning cylinder 2 and the first cover member 4 are installed in place, the scraping member 6 rotates and swings to the first position to form an interference structure for scraping off the dirty liquid on the first cleaning cylinder 2, and when the second cleaning cylinder 3 and the second cover member 5 are installed in place, the scraping member 6 rotates and swings to the second position to form a contact and pressure structure for scraping off the dirt on the second cleaning cylinder 3. In this way, only one scraping member 6 is needed to independently scrape off the dirty liquid and dirt from the first cleaning cylinder 2 and the second cleaning cylinder 3, so that the first cleaning cylinder 2 and the second cleaning cylinder 3 can be better kept in a clean state and can be better cleaned by clean water, effectively reducing secondary pollution to the ground, improving the overall cleaning effect of the ground, and improving the user experience.
