Description

Technical Field

[0001] The utility model relates to the field of cleaning tools, specifically, to a deformable mop head structure and a steam mop. Background Art

[0002] A steam mop is a household cleaning tool that uses water vapor to clean and disinfect the floor surface. Its working principle is to release the generated steam onto the floor through the mop head. The steam can soften and remove stains, grease, and other types of dirt. At the same time, the high-temperature steam can also kill microorganisms such as bacteria and viruses, achieving the effect of cleaning and disinfecting without using chemical cleaners.

[0003] For the existing steam mops, due to the relatively fixed structure of their mop heads, it is difficult to flexibly enter narrow or corner areas for thorough cleaning. Therefore, some cleaning dead corners may be left during use. To overcome the limitations of traditional steam mops when cleaning corners and narrow spaces, designers have developed steam mops with deformable mop heads. For example, a multi-functional water spraying mop disclosed in the utility model patent publication number CN215738764U, the mop head includes a main board and two sub-boards. The two sub-boards rotate around the main board, enabling the mop board to form a rectangular or triangular shape with the main board. Its rectangular mop can quickly clean the ground, and its triangular mop can strongly clean dead corners such as doors and windows.

[0004] However, for the deformable mop head of the above technical solution, through the rotation of the plates, the operation is relatively cumbersome and laborious. Moreover, when the two sub-boards after rotation are connected and fixed to the main board, it needs to be completed through a lock. The lock includes a lock ring, a lock catch, and a lock handle. Only when it is ensured that the lock is fully locked can it be ensured that the sub-board does not shake, and the operation is time-consuming.

[0005] Therefore, developing a deformable mop head structure with simple operation has become an urgent problem to be solved in the industry. Summary of the Utility Model

[0006] In order to solve the problems of the heavy structure and time-consuming and inconvenient operation of the existing deformable mop head, the utility model provides a deformable mop head structure and a steam mop.

[0007] The technical solution of the utility model is as follows:

[0008] A deformable mop head structure, characterized in that it includes a main body plate and two deformable rod assemblies symmetrically arranged on both sides of the main body plate, the main body plate is provided with a storage groove for accommodating the deformable rod assembly, the deformable rod assembly includes a first rod and a second rod movably connected; the deformable rod assembly can be converted between an expanded position and a storage position relative to the main body plate, and when the deformable rod assembly is in the storage position, the first rod and the second rod are overlapped and stored in the storage groove; when the deformable rod assembly is in the expanded position, the first rod and the second rod are expanded and extend out of the storage groove.

[0009] By adopting the above technical solution, the deformable rod assembly changes its state through the relative rotation of the first rod and the second rod, and has different positional relationships relative to the main plate in different states, so that the deformable rod assembly and the main plate are combined into different mop head shapes. When the deformable rod assembly is in the expanded position, the shape of the mop head is determined by the main plate and the deformable rod assemblies on both sides; when the deformable rod assembly is in the stored position, the shape of the mop head is only determined by the main plate.

[0010] The utility model according to the above scheme is characterized in that one end of the first rod is hinged to the main body plate, and the other end of the first rod is provided with a strip groove; one end of the second rod is hinged to the main body plate, and the other end of the second rod is provided with a rotating slider, and is hinged to the first rod through the rotating slider, and the rotating slider is slidably connected to the strip groove.

[0011] By adopting the above technical solution, the first rod and the second rod change their states by sliding the rotating slider to different positions of the strip groove. When the rotating slider slides to the inner end of the strip groove on the first rod, the first rod and the second rod overlap; when the rotating slider slides to the outer end of the strip groove on the first rod, the first rod and the second rod unfold.

[0012] Furthermore, the main body panel is an isosceles triangle, the hinged ends of the first rod and the main body panel and the hinged ends of the second rod and the main body panel are respectively arranged at both ends of the waist of the main body panel, and the first rod and the second rod on the same side are perpendicular to each other after being unfolded.

[0013] By adopting the above technical solution, when the first rod and the second rod of the deformable rod assembly on both sides of the main plate are relatively rotated to overlap and stored in the storage groove of the main plate, the mop head structure is an isosceles triangle; when the first rod and the second rod of the deformable rod assembly on both sides are unfolded to be perpendicular to each other and extend out of the storage groove, the mop head structure is a polygon with more than 3 sides.

[0014] Furthermore, the rotating slider includes a toggle plate and a base, the base is provided with a convex shaft, the convex shaft passes through the strip groove from bottom to top, the toggle plate is located above the strip groove and connected to the convex shaft, and the width of the toggle plate is greater than the width of the strip groove.

[0015] By adopting the above technical solution, the rotating slider slides in the strip groove through the convex shaft of the base, and the toggle piece clamped on the strip groove prevents the rotating slider from disengaging from the strip groove.

[0016] Furthermore, a wide notch is provided at one end of the strip groove close to the second rod; the second rod is provided with a hollow opening for accommodating the base, and the hollow opening is larger than the base. A first spring is provided between the side wall of the hollow opening and the base, and the first spring is used to apply a thrust or a pulling force to the base.

[0017] By adopting the above technical solution, when the first rod and the second rod are in the unfolded state and the rotating slider slides to the wide notch, at this time, under the action of the first spring, the convex shaft of the base deviates to one side of the wide notch, so that the convex shaft deviates from the central axis of the strip groove. Without external force, the convex shaft is stuck on one side of the wide notch, and the first rod and the second rod in the unfolded state are in a locked state and cannot move freely; when it is necessary to store the first rod and the second rod, the convex shaft of the base is pushed to the middle position of the wide notch through the toggle piece. At this time, the convex shaft is located on the central axis of the strip groove, and then the first rod and the second rod are pushed in the direction of the deformation rod assembly for storage. The convex shaft returns to slide in the strip groove until the first rod and the second rod are overlapped.

[0018] Furthermore, a first notch groove is provided on the inner side wall of the hollow opening, and a second notch groove is provided on the surface of the base facing the first notch groove. The first notch groove and the second notch groove form a spring groove for placing the first spring.

[0019] The utility model according to the above solution is characterized in that a rod placing groove is provided in the section where the second rod overlaps with the first rod.

[0020] The utility model according to the above solution is characterized in that at least one of the first rod and the second rod is provided with a torsion spring at the hinged end with the main body plate, and the torsion spring is used to drive the deformation rod assembly to extend out of the storage groove; the main body plate is provided with a locking control assembly, and the locking control assembly includes a locking part and a control part. The locking part is clamped with the first rod and / or the second rod located in the storage groove, and the control part is used to control the locking part to disengage from the first rod and / or the second rod.

[0021] By adopting the above technical solution, when the first rod and the second rod are located in the storage groove, at least one rod body is clamped with the locking part, so as to be locked in the storage groove of the main body plate, and the torsion spring cannot drive the deformation rod assembly to extend out of the storage groove; when the control part controls the locking part to disengage from the first rod and the second rod, under the action of the torsion spring, the deformation rod assembly extends out of the storage groove.

[0022] Further, a torsion spring is provided at one end of the first rod hinged to the main body plate. A clamping groove is provided at the end of the first rod away from the torsion spring, and the locking member is clamped with the clamping groove.

[0023] Furthermore, the locking control assembly further includes a bottom plate for mounting the control member and the locking member. The control member is a pedal, which can be a pressing pedal or an electric control pedal. The locking member includes a swing rod and a second spring. Both ends of the swing rod swing up and down with the middle position of the rod body as the center. A hook is provided at one end of the swing rod, and a second spring is provided on the lower surface of the other end. The hook is clamped in the clamping groove of the first rod, and the second spring is fixed to the bottom plate. The pedal abuts against the upper surface of the swing rod on the side of the second spring.

[0024] By adopting the above technical solution, the pedal is controlled to push down one end of the swing rod connected to the second spring. This end presses down and compresses the second spring, and the other end of the swing rod rises, so that the hook disengages from the clamping groove, and the first rod is in a free movement state.

[0025] Further, a cross-shaped convex block is provided on the lower surface of the other end of the swing rod, and the cross-shaped convex block is inserted into one end of the second spring.

[0026] Further, the bottom plate is provided with a support seat and a circular groove. The top of the support seat is provided with a fork opening, the side shaft of the swing rod is placed in the fork opening, and the other end of the second spring is inserted into the circular groove.

[0027] The present invention also provides a steam mop, which is characterized in that it includes the deformable mop head structure described in the above solution. Mop cloths are provided on the lower surfaces of the main body plate and the deformation rod assembly of the deformable mop head structure, and a steam outlet facing downwards is further provided on the main body plate.

[0028] According to the present invention of the above solution, the beneficial effects are as follows:

[0029] By arranging deformation rod assemblies on both sides of the main body plate, the mop head structure of the present invention can transform its form to be hidden in the storage groove of the main body plate or expand and extend out of the main body plate, so as to realize the shape change of the mop head structure and obtain a more suitable cleaning area requirement.

[0030] Moreover, the deformation rod assembly is composed of two simple rod bodies. When operating the deformation rod assembly to change its shape, only the relative rotation of the two light rod bodies is required to achieve it. Compared with the bulky rotating plate, the operation is more convenient. And in the two states of the deformation rod assembly, there is no need for the cumbersome steps of locking the lock between the first rod and the second rod, which is more time-saving and labor-saving.

[0050] The terms "first" and "second" are only used for the purpose of convenient description and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of technical features.

[0051] As Figures 1 to 5 shown, a deformable mop head structure includes a main body plate 1 and a deformable rod assembly 10. A deformable rod assembly 10 is provided on both the left and right sides of the main body plate 1, and two storage grooves 11 are correspondingly provided at the bottom of the main body plate 1 for storing the deformable rod assembly 10. The deformable rod assembly 10 includes a first rod 2 and a second rod 3, and the first rod 2 and the second rod 3 are movably connected. Specifically, the end of the first rod 2 is hinged to the second rod 3, and the end of the second rod 3 can slide along the first rod 2.

[0052] In the present utility model, the deformable rod assembly 10 can change its state through the relative rotation of the first rod 2 and the second rod 3. When the first rod 2 and the second rod 3 are superposed, the deformable rod assembly 10 is in a straight shape and located in the storage groove 11; when the first rod 2 and the second rod 3 are unfolded, the deformable rod assembly 10 is in a V shape and extends out of the storage groove 11. It can be seen that the deformable rod assembly 10 has different positional relationships with the main body plate 1 in different states, so as to form different shapes of the mop head in combination with the main body plate 1. When the deformable rod assembly 10 is in the storage position, the straight-shaped deformable rod assembly 10 is hidden in the main body plate 1, and the shape of the mop head is only determined by the main body plate 1; when the deformable rod assembly 10 is in the unfolded position, the V-shaped deformable rod assembly 10 is exposed from the main body plate 1, and the shape of the mop head is jointly determined by the main body plate 1 and the deformable rod assemblies 10 on both sides.

[0053] In this embodiment, the main body plate 1 is an isosceles triangle, and the deformable rod assemblies 10 on both sides are respectively located on the two waists of the isosceles triangle. Specifically, the hinge ends of the first rod 2 and the main body plate 1 and the hinge ends of the second rod 3 and the main body plate 1 are respectively arranged at both ends of the waist, and the first rod 2 and the second rod 3 of the same deformable rod assembly 10 are perpendicular to each other after being unfolded, forming a V shape with an included angle of 90°. When the first rods 2 and the second rods 3 on both sides of the main body plate 1 are superposed and stored in the corresponding storage grooves 11, the shape of the mop head is an isosceles triangle; when the first rods 2 and the second rods 3 on both sides of the main body plate 1 are unfolded, the shape of the mop head is a polygon with more than three sides. In a preferred embodiment, the deformable rod assemblies 10 on both sides form a quadrilateral with the main body plate 1 after being unfolded.

[0054] As Figure 2 and Figure 6 shown, in this embodiment, one end of the first rod 2 is hinged to the main body plate 1, and a strip-shaped groove 21 is provided at the other end of the first rod 2; one end of the second rod 3 is hinged to the main body plate 1, and a rotating slider 31 is provided at the other end of the second rod 3, and the second rod 3 is hinged to the first rod 2 through the rotating slider 31, and the rotating slider 31 is slidably connected in the strip-shaped groove 21 of the first rod 2. When the rotating slider 31 of the second rod 3 slides to the inner end (the end far from the second rod 3) of the strip-shaped groove 21 of the first rod 2, the first rod 2 and the second rod 3 are superposed; when the rotating slider 31 slides to the outer end of the strip-shaped groove 21, the first rod 2 and the second rod 3 are unfolded and perpendicular. In other alternative embodiments, the structures of the first rod 2 and the second rod 3 can be exchanged.

[0055] As Figure 3As shown, in this embodiment, the rotating slider 31 includes a toggle piece 312 and a base 311, and the base 311 is provided with a convex shaft 3111, which passes through the strip groove 21 from bottom to top and is connected to the toggle piece 312 located above the strip groove 21, and the convex shaft 3111 slides in the strip groove 21, and the width of the toggle piece 312 is greater than the width of the strip groove 21, so that the rotating slider 31 slides on the strip groove 21 without falling off. In other optional embodiments, the rotating slider 31 can also be an integrally formed component, and a clamping groove is provided at the position corresponding to the strip groove 21 in the middle of the component, and is slidably connected to the strip groove 21 through the clamping groove; the upper end of the component is larger than the strip groove 21, and the lower end of the component is equivalent to the base 311.

[0056] In this embodiment, a wide notch 211 is provided at the outer end of the strip groove 21 (the end close to the second rod 3), and the second rod 3 is provided with a hollow opening 33 for accommodating the base 311. The hollow opening 33 is larger than the base 311. The side walls of the base 311 and the hollow opening 33 are provided with a first spring 32. The first spring 32 can be in a compressed state to apply a thrust to the base 311, or in a stretched state to apply a pulling force to the base 311. The following is an explanation of the first spring 32 applying a thrust to the base 311.

[0057] When the convex shaft 3111 of the rotating slider 31 slides in the strip groove 21, the base 311 compresses the first spring 32, and there is a large gap between the side of the base 311 away from the first spring 32 and the hollow opening 33; when the rotating slider 31 slides to the outer end of the strip groove 21, the first rod 2 and the second rod 3 are fully unfolded, and since the convex shaft 3111 enters the wider slot 211 with a larger space, the base 311 is displaced in the hollow opening 33 under the pushing action of the first spring 32, and the convex shaft 3111 deviates to one side of the wide slot 211, thereby deviating from the central axis of the strip groove 21. In the absence of external force, the convex shaft 3111 is stuck on one side of the wide slot 211, and the first rod 2 and the second rod 3 in the unfolded state are in a locked state and cannot move freely. When the first rod 2 and the second rod 3 need to be folded, the convex shaft 3111 of the base 311 can be pushed to the middle position of the wide notch 211 by using the toggle piece 312, so that the convex shaft 3111 returns to the central axis of the strip groove 21. At this time, the first rod 2 and the second rod 3 are folded, and the convex shaft 3111 can smoothly enter the strip groove 21. As the first rod 2 and the second rod 3 are brought close to each other and overlapped, the rotating slider 31 slides to the inner end of the strip groove 21.

[0058] In an optional embodiment, the inner side wall of the hollow opening 33 is provided with a first notch groove 331, and the base 311 is provided with a second notch groove 3112 on the side opposite to the first notch groove 331. The first notch groove 331 and the second notch groove 3112 form a spring groove for placing the first spring 32. The first spring 32 is in a compressed state in the spring groove.

[0059] like Figure 2As shown, in the present embodiment, a section where the second rod 3 overlaps with the first rod 2 is provided with a rod placement groove 34. When the first rod 2 and the second rod 3 overlap, the first rod 2 is located in the rod placement groove 34. This structure makes the deformable rod assembly 10 more compact in the stored state, helps to reduce the size of the storage groove 11 of the main plate 1, and also facilitates hiding the deformable rod assembly 10 under the main plate 1.

[0060] In this embodiment, a torsion spring 23 is provided at the hinged end of the first rod 2 and the main body plate 1, and the torsion of the torsion spring 23 can drive the first rod 2 to rotate and extend out of the storage slot 11. The main body plate 1 is provided with a locking control assembly, which includes a locking member 4, a control member and a bottom plate 6. The locking member 4 is used to clamp the first rod 2 located in the storage slot 11, the control member is used to control the locking member 4 to be separated from the first rod 2, and the bottom plate 6 is used to install the locking member 4 and the control member.

[0061] like Figure 7 and Figure 8 As shown, specifically, the locking member 4 includes a swing rod 41 and a second spring 42. The swing rod 41 has the same principle as a seesaw, and the two ends of the swing rod 41 swing up and down with the middle position of the rod body as the center. A hook 411 is provided at the end of the swing rod 41 close to the first rod 2, and a cross-shaped protrusion (not shown in the figure) is provided at the other end. The cross-shaped protrusion is connected to one end of the second spring 42, and the other end of the second spring 42 is fixed to the bottom plate 6. The first rod 2 is provided with a snap-on groove 22. When the first rod 2 enters the receiving groove 11 of the main plate 1, the hook 411 hooks the snap-on groove 22, thereby limiting the free movement of the first rod 2, and the torsion spring 23 cannot drive the first rod 2 to rotate. The first rod 2 and the second rod 3 are fixed in the receiving groove 11 in a superimposed state.

[0062] The control member is a pedal 5, which can be a pressing pedal or an electric control pedal. The pedal 5 abuts against the upper surface of the second spring 42 of the swing rod 41. When the pedal 5 is moved downward by an external force, the end of the swing rod 41 is pushed downward to press the second spring 42; one end of the hook 411 of the swing rod 41 tilts upward, and the hook 411 is disengaged from the clamping groove 22 of the first rod 2, so that the first rod 2 resumes a free activity state. At this time, under the action of the torsion spring 23, the first rod 2 rotates and extends out of the storage groove 11 of the main plate 1. It can be seen from the structure of the above-mentioned deformation rod assembly 10 that the second rod 3 rotates at the same time, so the deformation rod assembly 10 unfolds and extends out of the storage groove 11. When the pedal 5 is not subjected to external force, the elastic potential energy of the second spring 42 causes the adjacent end of the swing rod 41 to rise, and the pedal 5 rises synchronously, and one end of the hook 411 of the swing rod 41 is pressed downward. When the user actively retracts the first rod 2, since the outer side of the hook 411 has an inclined surface, the first rod 2 collides with the hook 411 when entering the storage groove 11, and smoothly lifts one end of the hook 411 of the swing rod 41 through the inclined surface. After the first rod 2 is in place, the hook 411 engages with the first rod 2.

[0063] In other alternative embodiments, a torsion spring is provided at the hinged end of the second rod and the main body plate, or torsion springs are provided on both the first rod and the second rod. In other alternative embodiments, the locking member clamps the second rod located in the receiving groove. At this time, the position of the swing rod is correspondingly adjusted under the base, so that its hook is convenient for clamping the second rod; or the locking member has two swing rods symmetrically arranged up and down, which respectively clamp the first rod and the second rod.

[0064] In this embodiment, the bottom plate 6 is provided with a support seat 61 and a circular groove 62. The top of the support seat 61 is provided with a fork opening. A side shaft is provided on the side wall at the central position of the swing rod 41, and the side shaft is placed in the fork opening to realize the up and down swing of both ends of the swing rod 41. The other end of the second spring 42 is inserted into the circular groove 62 to realize the fixed connection between the second spring 42 and the base 311.

[0065] The present utility model also provides a steam mop. The mop head of the steam mop is provided with a steam generating device for generating water vapor. The mop head includes the deformable mop head structure described in the above solution. The deformable mop head structure includes a main body plate 1 and deformation rod assemblies 10 located on both sides of the main body plate. Mop cloths are provided on the lower surfaces of the main body plate 1 and the deformation rod assemblies 10. The mop cloths are unfolded or folded as the deformation rod assemblies 10 change their shapes. The main body plate 1 is provided with a steam outlet 12 facing downward, and the water vapor generated by the steam generating device is discharged from the steam outlet 12.

[0066] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0067] The above embodiments only represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
