Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning appliances, in particular to a hands-free cleaning device. BACKGROUND

[0002] With the acceleration of modern life pace, people's demand for household cleaning tools is increasing, especially the requirements of convenience, efficiency and hygiene are increasing. There are some hands-free cleaning tools on the market, but they all have different degrees of defects. For example, the static brush hair device and the convenient hair removal brush, although they use straight rods to achieve hair cleaning by scraping and are free of hand cleaning, their functions are limited to clothing hair removal and ball trimming, dust removal, etc., and they cannot be used for regular cleaning operations and cannot be wet. The material is ABS plastic, the straight rod is too hard to bend, it cannot clean the edge seam position, the cleaning material uses polyester silk sleeve embedding, and it cannot achieve 360° cleaning due to the influence of the ABS plastic clamping edge on both sides. It can only clean the hair and dust on the front and back planes, and the scraping part has no comb teeth or serrations. The dirty polyester silk surface needs to be cleaned separately. The desktop mini hands-free cleaning tool and the hands-free flat mop have scraping design and can clean the mop by squeezing water through the push button and pull rod. The scraping strips on both sides can clean the floating foam, and the bidirectional rotating joint can be placed flat at 180° to clean part of the gap. However, they can only clean flat surfaces, and the 180° rotating rod can only clean part of the gap. Due to the influence of single-sided straight plate and hardness, many card seam positions cannot be cleaned. It can only be cleaned on one side, and the cleaning sleeve can only be replaced with the same type. The scraping design only has a push button, no serrations, combs, or brushes, and the mop cleaning effect is limited. The mini hands-free mop and the sponge mop can only clean one side and cannot clean 360° without dead angles. The sponge mop head is used, which has poor water absorption and is easy to dry and harden. It can only replace the same type of sponge mop head and cannot adapt to other materials. The 180° rotating head has limited effect on gap cleaning. The cleaning cotton head is designed to fold inward and can only squeeze water. It cannot clean the cotton head and accumulate water, mold, and dirt.

[0003] However, the existing cleaning tools have several disadvantages. First, the function is single and the application scene is limited. During the cleaning process, it often needs to be frequently cleaned and squeezed by hand, which not only wastes time and effort, but also may cause secondary pollution. Second, the material selection is not appropriate, including the material of the cleaning rod and the material of the cleaning sleeve. Both have limitations. Most of the main rods of the cleaning supplies on the market are made of hard materials, which cannot better fit the cleaning surface. The cleaning supplies can only be replaced with the same type of material (such as cloth, cotton head, fiber cloth, and silicone). This is not conducive to resource conservation and environmental protection. Third, it can only achieve single-sided cleaning. The size of the cleaning tool limits the depth of the gap and the edge seam, which is not convenient and efficient. SUMMARY

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the accompanying drawings and specific circumstances.

[0023] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0024] This invention provides a hands-free cleaning device, which can be referred to as follows: Figures 1-3 The device includes a main rod 1, an extension rod 2, a cleaning cloth cover 3, a locking mechanism 4, and a scraping mechanism 5. The main rod 1 has a cleaning section 11 and a handle section 12 connected to the cleaning section 11; the cleaning section 11 and the handle section 12 are integrally formed, with a smooth transition at their connection. Specifically, the cleaning section 11 is used to fit and expand the cleaning cloth cover 3; its flat structure helps increase the contact area between the cleaning cloth cover 3 and the surface to be cleaned, improving cleaning efficiency. The handle section 12 provides a handheld part for the user, serving as the point of force application for the device. The extension rod 2 is telescopically located within the handle section 12, used to extend the length of the main rod 1, thereby expanding the user's operating radius. This allows for cleaning of farther or higher areas without bending over or moving the body, improving its ease of use and applicability.

[0025] A cleaning cloth cover 3 is fitted over the outside of the cleaning section 11. Specifically, the cleaning cloth cover 3 is a sleeve-shaped structure with one open end, extending to the connection between the cleaning section 11 and the handle section 12, directly contacting the surface to be cleaned, and absorbing dirt and water stains through wiping. A locking mechanism 4 is provided on the cleaning cloth cover 3 and detachably connected to the end of the cleaning section 11, used to lock the cleaning cloth cover 3 onto the cleaning section 11. A scraping mechanism 5 is fitted over the locking mechanism 4 and has scraping bristles 51 facing the surface of the cleaning cloth cover 3, used to scrape the surface of the cleaning cloth cover 3 to remove dirt when the cleaning cloth cover 3 moves relative to the scraping mechanism 5.

[0026] As an embodiment of the present embodiment, reference can be made to Figure 4 The main rod 1 is in a flat rod structure, and is made of a material with compressibility, resilience and high toughness.

[0027] Specifically, the flat structure of the main rod 1 provides a stable support surface for the outer cleaning cloth sleeve 3, so that the cleaning cloth sleeve 3 can be fully stretched and form a more uniform contact with the surface to be cleaned, thereby improving the cleaning efficiency and effect, and effectively preventing the cleaning cloth sleeve 3 from twisting or slipping on the main rod 1.

[0028] In addition, the flat structure of the main rod 1 provides a stable and reliable combination surface for the locking mechanism 4, ensuring the firmness of the locking mechanism 4 on the main rod 1. At the same time, it provides positioning and guidance for the outer scraping mechanism 5, so that it can only move along the extension direction of the main rod 1, ensuring the scraping effect on the cleaning cloth sleeve 3.

[0029] In use, the flat handle section 12 conforms to the ergonomics, and the hand feels more stable when holding, facilitating the application and control of force during pushing and pulling cleaning actions.

[0030] In specific implementation, the main rod 1 can also adopt a circular, fork-shaped or other special-shaped structure (including but not limited to a clamping plate type, a Swiss-knife type, an umbrella type and various shaped structures, but the material of the main rod is still limited to a compressible and resilient material).

[0031] The main rod 1 is made of a material with compressibility, resilience and high toughness. In the cleaning process, when encountering slightly uneven surfaces or surfaces with curvature, the slight compressive deformation capability of the main rod 1 can make the cleaning section 11 and the cleaning cloth sleeve 3 thereon better adhere to the cleaning surface, ensuring a dead-angle-free cleaning effect.

[0032] In the present embodiment, the material of the main rod 1 includes but is not limited to PP material, silica gel material, polyurethane and stainless steel (such as a stainless steel ruler).

[0033] As an embodiment of the present embodiment, reference can be made to Figure 5 The width of the cleaning section 11 is greater than that of the handle section 12. In the normal state, the scraping mechanism 5 is sleeved on the locking mechanism 4. When cleaning or replacing the scraping mechanism 5 is needed, the scraping mechanism 5 is detached from the locking mechanism 4, and then the scraping mechanism 5 can be removed from the handle section 12. The limit round corners 111 are symmetrically arranged on both sides of the end of the cleaning section 11 away from the handle section 12, so that when the scraping mechanism 5 reciprocates on the cleaning section to scrape and clean the cleaning cloth sleeve 3, the scraping mechanism 5 is prevented from falling off from the front end of the cleaning section 11.

[0034] As an embodiment of the present embodiment, reference can be made toFigure 5 The handle section 12 is provided with a sliding cavity 121, and the extension rod 2 is slidingly arranged in the sliding cavity 121. By pulling out or pushing into the extension rod 2 from the sliding cavity 121, the user can conveniently and quickly adjust the total length of the main rod 1, so as to improve the application range and use convenience of the product.

[0035] As an embodiment of the present embodiment, reference can be made to Figure 3 The cleaning cloth sleeve 3 is made of water-absorbing material and has elasticity to be closely sleeved on the cleaning section 11. The water-absorbing material of the cleaning cloth sleeve 3 can quickly absorb and contain liquid stains (such as water stains and oil stains), effectively remove solid dust and dirt through wiping, and achieve the purpose of cleaning the surface. At the same time, when the scraping mechanism 5 scrapes the cleaning cloth sleeve 3, the water-absorbing material can temporarily store the liquid stains and release them when subjected to scraping pressure, thereby completing the peeling of the dirt.

[0036] At the same time, the cleaning cloth sleeve 3 is elastically sleeved on the cleaning section 11 of the main rod 1, which can effectively prevent the cleaning cloth sleeve 3 from slipping, twisting or falling off relative to the main rod 1 during forward and backward pushing and pulling cleaning or upward and downward scraping, and ensure the effective transmission of the cleaning action.

[0037] As an embodiment of the present embodiment, reference can be made to Figure 6 The locking mechanism 4 includes a first clamping plate 41, a second clamping plate 42 and a fixing bolt 43. The first clamping plate 41 is in a U-shaped structure, the inner side shape of which matches and is clamped on the upper side of the cleaning section 11 of the main rod 1. The second clamping plate 42 is in a U-shaped structure, the inner side shape of which matches and is clamped on the lower side of the cleaning section 11 of the main rod 1. The second clamping plate 42 and the first clamping plate 41 are opposite to each other to form a fixing frame covering the end of the main rod 1. The fixing bolt 43 penetrates the first clamping plate 41, the end of the cleaning cloth sleeve 3, the main rod 1 and the second clamping plate 42 in sequence and is locked by a fixing nut, so as to clamp and fix the open end of the cleaning cloth sleeve 3 to the end of the cleaning section 11.

[0038] Through the cooperation of the first clamping plate 41 and the second clamping plate 42 and the fixing of the fixing bolt, the end of the cleaning cloth sleeve 3 can be wrapped and fixed on the main rod 1, so as to ensure the firmness of the connection between the cleaning cloth sleeve 3 and the main rod 1. At the same time, the fixing frame formed by the second clamping plate 42 and the first clamping plate 41 opposite to each other can provide a stable and reliable sleeving base for the scraping mechanism 5, so as to ensure the fixation of the scraping mechanism 5 in the non-working state.

[0039] As an embodiment of the present embodiment, reference can be made to Figure 7 The scraping mechanism 5 includes a scraping frame 52 and scraping bristles 51. The scraping frame 52 is in a U-shaped structure, the inner side shape of which matches and is clamped on the outer side of the cleaning cloth sleeve 3. The scraping bristles 51 are arranged on the inner side of the scraping frame 52. The scraping frame 52 is a mouth-shaped frame, which is slidably sleeved outside the locking mechanism 4 composed of the first clamping plate 41 and the second clamping plate 42. The mouth-shaped structure can ensure that the scraping mechanism 5 can only move along the axial direction of the main rod 1 and cannot rotate or deviate laterally. Meanwhile, as the basic framework of the entire scraping mechanism 5, it is used to fix and support the upper and lower groups of scraping bristles 51.

[0040] The inner walls of the scraping frame 52 on both sides in the length direction are adapted to the outer side of the locking mechanism 4, which can realize the matching arrangement of the limiting mechanism 53, and further ensure the relative fixation of the position between the scraping frame 52 and the locking mechanism 4 in the non-working state.

[0041] The scraping bristles 51 are provided in two groups, which are fixedly arranged on the upper and lower sides of the internal frame of the scraping frame 52 and extend towards and keep contact with the surface of the cleaning cloth sleeve 3. When the scraping frame 52 reciprocally moves along the cleaning cloth sleeve 3, the scraping bristles 51 on the upper and lower sides inside the scraping frame 52 scrape and squeeze out the dirt and water stains penetrated in the fibers of the cleaning cloth sleeve 3 by using the friction force, so as to realize the preliminary dehydration and decontamination of the cleaning cloth sleeve.

[0042] The cross section of the scraping bristle 51 is in a conical structure. The conical structure makes the tip of the bristle thinner and more flexible, which is easy to penetrate into the fiber gap of the cleaning cloth sleeve 3 for cleaning. Meanwhile, the root of the bristle is thicker, which can provide sufficient support force to ensure the scraping degree. Moreover, the scraped dirt and water stains can be guided and collected along the conical slope, which is convenient for discharge.

[0043] The scraping bristle 51 is internally provided with at least one through hole 511 penetrating through the body thereof. The arrangement of the through hole 511 reduces the cross-sectional area of the bristle, so that it is easy to bend and deform when subjected to pressure, which provides a soft scraping feeling and reduces the potential damage to the fibers of the cleaning cloth sleeve 3. Meanwhile, part of the liquid and small dirt scraped off can temporarily enter the through hole 511 or be squeezed out when the bristle deforms, which helps to form a more complex fluid channel between the bristle and the cloth sleeve, thereby improving the scraping efficiency and self-cleaning ability.

[0044] As an embodiment of the present embodiment, reference can be made to Figures 6-7 The scraping mechanism 5 further includes a limiting mechanism 53, which includes a first limiting magnet 531 and a second limiting magnet 532. The first limiting magnet 531 is provided in two, which are fixedly embedded in the inner walls on both sides in the length direction of the scraping frame 52. The second limiting magnet 532 is provided in two, which are fixedly arranged on the outer walls of the first clamping plate 41 and the second clamping plate 42 of the locking mechanism 4 and correspond to the positions of the first limiting magnet 531 one by one. When the scraping frame 52 is sleeved on the locking mechanism 4, the first limiting magnet 531 and the corresponding second limiting magnet 532 are mutually adsorbed by magnetic attraction, so as to detachably position the scraping frame 52 on the locking mechanism 4.

[0045] In the non-working state, when the user puts the scraping mechanism 5 back into the locking mechanism 4, the first limiting magnet 531 and the second limiting magnet 532 are automatically attracted when they are close, and a clear suction force is generated at this time, indicating that the scraping mechanism 5 has been installed in place and can be confirmed without visual inspection. At the same time, the first limiting magnet 531 and the second limiting magnet 532 are connected by magnetic attraction, without any mechanical structure such as buckles, threads, etc., making the separation and cooperation between the scraping mechanism 5 and the locking mechanism 4 simple and fast.

[0046] Similarly, the limiting mechanism 53 can also use other connection methods such as card slots and point buckling.

[0047] In the specific implementation of the present application: 1) Preparation and cleaning stage: The cleaning cloth cover 3 is sleeved into the cleaning section 11 of the main rod 1 from the open end. Since the cleaning section 11 has a flat structure, it can effectively expand the cloth cover to form a larger cleaning surface. At the same time, the elasticity of the cleaning cloth cover 3 itself enables it to tightly wrap the cleaning section 11, preventing it from sliding or twisting during subsequent operations.

[0048] The first clamping plate 41 and the second clamping plate 42 of the locking mechanism 4 are respectively clamped on the upper and lower sides of the end of the cleaning section 11 with the sleeved cleaning cloth cover 3, forming a complete fixed frame. Then, the fixing bolt 43 is successively inserted through the first clamping plate 41, the end of the cleaning cloth cover 3, the main rod 1, and the second clamping plate 42, and locked with the fixing nut, firmly clamping and fixing the open end of the cleaning cloth cover 3 at the end of the main rod 1, completing the assembly of the device.

[0049] In use, the user can pull out the extension rod 2 from the sliding cavity 121 of the handle section 12 according to the distance or height of the area to be cleaned, to expand the operation radius and achieve standing cleaning of high or distant places without bending over.

[0050] During cleaning, the user holds the ergonomic flat handle section 12 and pushes the device towards the surface to be cleaned. The cleaning cloth cover 3 contacts the surface, adsorbing liquid stains (such as water stains) and removing solid dust. When encountering uneven or curved surfaces, the "pressable and resilient" property of the main rod 1 material allows the cleaning section 11 to deform slightly, driving the cleaning cloth cover 3 to better fit the surface and ensure thorough cleaning without dead angles.

[0051] 2) Scrubbing and self-cleaning stage: When the cleaning cloth cover 3 adsorbs a large amount of dirt and moisture and needs to be cleaned, the user holds the scraping frame 52 of the scraping mechanism 5 with his hand, overcomes the magnetic attraction between the first limiting magnet 531 and the second limiting magnet 532, and pulls it out of the locking mechanism 4 along the main rod 1 axis.

[0052] At this time, one hand holds the handle section 12, and the other hand repeatedly pushes and pulls the scraping mechanism 5 to make it reciprocate on the cleaning section 11 of the main rod 1 with the cleaning cloth cover 3. During the movement of the scraping mechanism 5, the scraping bristles 51 fixed on both sides of the scraping frame 52 are always in contact with and rub against the surface of the cleaning cloth cover 3. The tapered bristle tips can penetrate into the fiber gaps of the cleaning cloth cover 3 and scrape and squeeze out the dirt penetrated therein. At the same time, the bristles apply pressure to the cleaning cloth cover 3 and strongly squeeze out the liquid (sewage) absorbed by the cleaning cloth cover 3 to achieve preliminary dehydration. When the scraping mechanism 5 reciprocates to the front end of the cleaning section 11, the limiting round corners 111 on both sides play a mechanical blocking role and effectively prevent the scraping mechanism 5 from falling off the front end of the main rod 1 due to inertia or excessive force.

[0053] 3) Reset and maintenance phase: After the cleaning is completed, the user pushes the scraping mechanism 5 back to the end of the main rod 1. When the scraping frame 52 is covered back to the locking mechanism 4, the first limiting magnet 531 on the inside thereof is automatically aligned with and attracted to the second limiting magnet 532 on the locking mechanism 4, producing a clear hand feeling and sound. This indicates that the scraping mechanism 5 has been accurately reset and magnetically stably positioned in the non-working position, ready for the next use.

[0054] When the cleaning cloth cover 3 needs to be deeply cleaned or replaced, the fixing bolt 43 is simply loosened, the locking mechanism 4 is opened, and the dirty cloth cover can be removed.

[0055] When the scraping mechanism 5 needs to be cleaned, it is completely removed from the locking mechanism 4. Since the width of the cleaning section 11 is greater than that of the handle section 12, the removed scraping mechanism 5 can be smoothly slid out from the relatively narrow handle section 12, facilitating its washing or wiping.

[0056] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of various changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
