Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaning equipment technology, and in particular to a vacuum cleaning head that can be used for attaching to a vacuum cleaning device. Background Technology

[0002] Portable vacuum cleaners, especially handheld ones, have become essential cleaning tools in modern homes due to their lightweight and flexible features. To further improve cleaning efficiency and meet users' needs for deep cleaning, integrated vacuuming and mopping heads have emerged on the market. These dual-purpose cleaning heads can be attached to the lower end of the rigid tube of a portable vacuum cleaner. During operation, the powerful suction removes dust and larger particles, while a wet cleaning pad (such as a cloth) installed at the bottom wipes the surface, thus achieving simultaneous vacuuming and mopping, greatly simplifying the cleaning process.

[0003] However, existing vacuum and mop cleaning heads have several inconveniences in terms of the way they fix the cleaning pads, affecting the user experience. Currently, the mainstream fixing methods include: Velcro (i.e., burr-fastened) fixing, clamping or snap-on fixing, and angle retainer fixing. While Velcro fixing is relatively convenient, its fixing strength is insufficient, and the cleaning pad is prone to shifting or falling off during dragging. Clamping or snap-on fixing requires the user to forcefully insert or pry open the clamp, which is laborious, and when removing a wet cleaning pad, the user's hands are easily exposed to the dirty parts, resulting in poor hygiene. Angle retainer fixing involves inserting the four corners of the cleaning pad into specific corner fixing devices. While this method may provide a relatively secure fixation, the installation and removal process is usually more cumbersome, requiring the user to precisely align the four corners and operate one by one, which is time-consuming and laborious, and does not allow for quick replacement. Utility Model Content

[0004] In order to solve the problems mentioned above, the purpose of this utility model is to provide a cleaning head that can be used for both vacuuming and mopping, with a convenient and quick cleaning pad that can be disassembled and installed.

[0005] Therefore, this application provides a vacuum and mop cleaning head, comprising: a housing configured to support a cleaning pad, the housing including a bottom and a top opposite each other; and a suction nozzle that can be flipped upwards and backwards to the top. A connecting pipe, rotatably connected to the top; a water tank, detachably mounted on the top and configured to store water to be supplied to the cleaning pad, the water tank having a bottom wall; when the water tank is mounted on the top, the bottom wall is capable of pressing a pair of opposing front and rear sides of the cleaning pad against the top; and a magnetic structure, disposed between the bottom of the water tank and the top, the water tank being able to be attracted and engaged to the top by the magnetic structure.

[0006] In some embodiments, the water tank has a clearance notch to allow for the suction nozzle and the connecting pipe connected to the top.

[0007] In some embodiments, the water tank has a fluid-through left side portion, a right side portion, and a middle connecting portion, the middle connecting portion being located between the left side portion and the right side portion, and the thickness of the middle connecting portion measured in the vertical direction being less than the thickness of the left side portion and the right side portion measured in the vertical direction; when the water tank is installed on the top, the left side portion and the right side portion are located on the left and right sides of the connector, and the middle connecting portion is located below the rear side of the connecting pipe.

[0008] In some embodiments, the vacuum and mop cleaning head further includes a water supply path disposed in the housing and extending from the top to the bottom.

[0009] In some embodiments, the top defines a receiving recess; when the water tank is mounted on the top, the lower part of the water tank is placed into the receiving recess.

[0010] In some embodiments, the top has a top wall defining the bottom of the receiving groove, and a pair of opposing front and rear sides of the cleaning pad can be pressed between the top wall and the bottom wall.

[0011] In some embodiments, the top wall and / or the bottom wall are provided with a plurality of protrusions.

[0012] In some embodiments, the housing is rectangular and the top wall is lower than the front edge, rear edge, left edge and right edge of the top.

[0013] In some embodiments, the water tank has an outlet located on the bottom wall, and the top of the water tank is provided with an air inlet that communicates with the outside atmosphere and an operable switch for opening and closing the air inlet.

[0014] In some embodiments, the nozzle has a suction position close to the floor to be cleaned and a release position that flips back and up above the housing; when the nozzle is in the release position, the front side of the cleaning pad can be folded from the front side of the housing to the top.

[0015] Compared with existing technologies, the beneficial effects of this application are as follows: This application eliminates the need for an additional cleaning pad fixing mechanism. Through the installation of the water tank, it integrates the functions of fixing the cleaning pad and providing a water source, achieving a "one-installation-multiple-use" effect. It simplifies the operation process and enhances the user experience: Users no longer need to worry about how to fix the mop; preparation is completed in just two steps: "place the cleaning pad" and "attach the water tank." This greatly simplifies the installation and replacement process of the cleaning pad, making the operation intuitive and quick. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] Please see Figures 1 to 4 The present invention provides a vacuum and mop cleaning head 100, the main improvement of which is that by using a detachable water tank in conjunction with the top of the housing, the water tank’s own weight and bottom wall, combined with the magnetic adsorption force, together press and fix the front side 801 and rear side 802 of the cleaning plate 800, which are opposite to each other, so as to realize the quick, firm and convenient installation and removal of the cleaning plate 800.

[0019] like Figure 1 and Figure 2 As shown, the vacuum and mop cleaning head 100 mainly includes a housing 1, a suction nozzle 2, a connecting tube 3, and a water tank 4.

[0020] The housing 1 is generally rectangular, comprising a bottom 11 and a top 12. The housing 1 is configured to support a cleaning pad 800, which is typically a cloth or a fabric / non-woven sheet with similar cleaning functions. Furthermore, the bottom 11 of the housing 1 may have a padding layer 13. The padding layer 13 may be made of an elastic material (such as foam, sponge, or silicone), and its function is to provide flexible support for the cleaning pad 800, allowing it to better conform to uneven surfaces and improve cleaning effectiveness.

[0021] The nozzle 2 is connected to the front of the top 12 in a rearward and upward flip-up manner via a pivot or hinge structure. The nozzle 2 has two working positions: one is the vacuuming position facing the surface to be cleaned (e.g.,...). Figure 1 , Figure 2 As shown), vacuuming can be performed at this time; secondly, flip it backward and upward to the release position above housing 1 (as shown). Figure 3 and Figure 4 In this position, the front side 801 of the cleaning sheet 800 can be easily folded from the front of the housing 1 to the top 12, facilitating the installation or replacement of the cleaning sheet 800. Of course, when the vacuuming and mopping cleaning head 100 is cleaning the floor to be cleaned, if vacuuming is not required, the nozzle 2 can be switched to the release position, so that the suction port of the nozzle 2 leaves the floor to be cleaned.

[0022] The connecting pipe 3 is rotatably connected to the top 12. The connecting pipe 3 can be connected to the dust inlet pipe of a vacuum cleaner main unit (not shown in the figure). The connecting pipe 3 and the nozzle 2 are in fluid communication through a flexible hose (not shown in the figure), so that the suction force generated by the vacuum cleaner main unit can be transmitted to the nozzle 2.

[0023] The water tank 4 is detachably mounted on the top 12 of the housing 1. The water tank 4 is configured to store clean water or cleaning fluid to be supplied to the cleaning plate 800. To achieve a compact design, the water tank 4 has clearance notches 40 to allow passage between the suction nozzle 2 and the connecting pipe 3 connected to the top 12. Specifically, the water tank 4 has a fluid-through left side portion 41, a right side portion 42, and a central connecting portion 43. The central connecting portion 43 is located between the left side portion 41 and the right side portion 42, and its thickness measured vertically is less than that of the left side portion 41 and the right side portion 42. When the water tank 4 is mounted on the top 12 of the housing 1, the left side portion 41 and the right side portion 42 are located on the left and right sides of the connecting pipe 3, while the central connecting portion 43 is located below and behind the connecting pipe 3. This structure cleverly utilizes the space around the connecting pipe 3; the assembly and disassembly of the water tank 4 are unaffected by the connecting pipe 3, and the presence of the water tank 4 does not affect the rotation of the connecting pipe 3 relative to the top 12.

[0024] When the water tank 4 is installed on the top 12, the lower part of the water tank 4 is placed in the receiving groove 120, which helps to position the water tank 4 and reduces the overall height, making the structure more compact. The top 12 has a top wall 121 that defines the bottom of the receiving groove 120. The front side 801 and rear side 802 of the cleaning plate 800 can be pressed between the top wall 121 and the bottom wall 411 of the water tank 4. The top wall 121 is lower than the front edge, rear edge, left edge and right edge of the top 12. The receiving groove 120 is equivalent to forming a sunken platform at the top 12 of the housing 1, which helps to position the cleaning plate 800. In order to increase friction and prevent the cleaning plate 800 from shifting, a number of protrusions 48 can be provided on the top wall 121 and / or the bottom wall 411 of the water tank 4.

[0025] To hold the water tank 4 within the receiving groove 120 of the top 12, multiple magnetic structures 5 are arranged between the bottom and top 12 of the water tank 4. Specifically, magnets can be embedded or fixed around the bottom wall 411 of the water tank 4, and iron plates or another set of magnets can be placed at corresponding positions on the top wall 121 of the top 12 of the housing 1 or in the receiving groove 120. The water tank 4 can be securely attached to the top 12 by the magnetic attraction of the magnetic structures 5. The magnetic structures 5 not only provide additional fixing force but also provide a clear sense of positioning for the user when installing the water tank 4.

[0026] When installing the cleaning pad 800, the vacuum and mop cleaning head 100 first lays the cleaning pad 800 flat on the bottom 11 of the housing 1, then folds its front side 801 and rear side 802 upwards to cover the top wall 121 of the top 12. Next, the water tank 4 is aligned and placed into the receiving groove 120 of the top 12. As the water tank 4 falls, the magnetic structure 5 activates, assisting in guiding and ultimately firmly adhering the water tank 4 to the top 12. During this process, the weight of the water tank 4 itself, combined with the adsorption force of the magnetic structure 5, acts on its bottom wall 411, tightly pressing the front side 801 and rear side 802 of the cleaning pad 800 against the top wall 121, thus achieving quick and reliable fixation. For disassembly, simply lift the water tank 4 upwards to release the pressure on the cleaning pad 800, facilitating replacement.

[0027] To enable the mopping function, a water supply path (not shown in the figure) is also included. This path is located within the housing 1 and extends from the top 12 to the bottom 11, guiding water from the water tank 4 to the cleaning pad 800. The water tank 4 has an outlet (not shown in the figure) located on the bottom wall 411. To control the water flow, the top of the water tank 4 may also have an air inlet connected to the outside atmosphere and an operable switch 45 for opening and closing the air inlet. When the air inlet is opened, air enters the water tank 4, and water flows out from the outlet under gravity; closing the air inlet stops the water flow. In this example, the operating switch 45 is located on the top of the left side 41 of the water tank 4. The top of the right side 42 of the water tank 4 has a water inlet (not shown in the figure) and a liftable water inlet cap 46 covering the inlet.

[0028] This design achieves three functions simultaneously through the installation of a water tank: providing water to the cleaning pads, securing them, and acting as a counterweight / pressure block. Specifically, by supplying water to the cleaning pads, it enables wet mopping. The weight of the water tank itself and its bottom wall structure firmly press the cleaning pads against the top of the casing, preventing them from shifting, curling, or falling off during cleaning. Furthermore, the weight of the water tank is evenly distributed across the cleaning pads through the bottom wall, ensuring full contact between the pads and the floor, thus increasing mopping pressure and cleaning efficiency. It eliminates the need for traditional complex mechanical structures such as Velcro, clips, and clamps specifically designed to secure the cleaning pads. This not only reduces the number of parts and cost but also improves product reliability.

[0029] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
