Technical Field
[0001] The present invention relates to the technical field of cleaning equipment, and particularly to a mop head. Background Art
[0002] A mop is a common household cleaning tool, which includes a long handle for the user to hold and a mop head attached to the bottom of the long handle. The user can push and pull the mop head on the ground by using the long handle to perform a cleaning operation. There is a type of mop with replaceable cleaning cloths, which generally has a clamping component on the mop head for selectively clamping the cleaning cloth. After the cleaning cloth becomes dirty, the user unlocks the clamping component to make the cleaning cloth detach from the mop head so as to replace it with a new one.
[0003] However, the traditional mop with replaceable cleaning cloths has a technical problem that it cannot switch the inner and outer surfaces of the cleaning cloth, that is, after the outer surface (the side surface exposed to the outside) of the cleaning cloth of the mop becomes dirty, it cannot switch the relatively clean inner surface (the side surface not exposed to the outside) to the outside. This makes the user have to frequently replace the cleaning cloth during the cleaning operation, which reduces the cleaning efficiency to a certain extent. In addition, the frequent cloth replacement operation also causes the user's hands to be repeatedly contaminated by the dirty cleaning cloth, which is not conducive to the user's health. When cleaning places with a large cleaning volume such as hotels and shopping malls, the inconveniences brought by the above technical problems are particularly prominent. Summary of the Invention
[0004] In view of the above technical problems, the present invention provides a mop head that can switch the inner and outer surfaces of the cleaning cloth.
[0005] To achieve the above technical effects, the present invention provides the following technical solutions: A mop head includes a mop bracket, a plate retainer rotatably connected to the mop bracket, a pair of flipping plates that can respectively clamp the two end portions of the cleaning cloth, and a locking mechanism that can lock the pair of flipping plates to the plate retainer. The pair of flipping plates are arranged front and back relative to each other. The pair of flipping plates are respectively rotatably connected to the plate retainer around a first rotation axis extending left and right and a second rotation axis parallel to the first rotation axis. The sum of the maximum rotation radii of the pair of flipping plates is not greater than the distance between the first rotation axis and the second rotation axis.
[0006] In the above technical solution, preferably, the flipping plate includes a clamping portion for clamping the cleaning cloth. When the flipping plate is locked to the plate retainer, the clamping portion is located on the outermost side of the flipping plate. It can be further preferably that the clamping portion is arranged at the middle position of the flipping plate in the thickness direction.
[0007] In the above technical solution, preferably, the flip plate includes a groove extending in the left-right direction and a cleaning cloth pressure strip adapted to the groove.
[0008] In the above technical solution, preferably, the locking mechanism includes a pair of locking units that can respectively lock a pair of the flip plates, each of the locking units includes at least one locking slot and at least one movable latch matched with the at least one locking slot, one of the at least one locking slot and the at least one movable latch is arranged on the plate holder, and the other is arranged on the flip plate. It is also further preferred that the at least one movable latch is arranged on the flip plate, and the locking unit also includes an operating member that is transmission-connected to the latch, and the operating member is configured to be suitable for single-finger operation by the user. It is also further preferred that at least one guide groove that is matched with the at least one operating member is provided on the flip plate, and the operating member is accommodated in the guide groove.
[0009] In the above technical solution, preferably, the plate holder includes a pair of holding plates opposite to each other, and the pair of flip plates are located inside the pair of holding plates. It is also further preferred that each of the holding plates has a first end and a second end that are away from each other, and the first rotation axis and the second rotation axis pass through the pair of first ends and the pair of second ends respectively.
[0010] In the above technical solution, preferably, the mop bracket is provided with a connector for connecting the long handle.
[0011] Compared to the prior art, the mop head provided by the technical solution of the present invention is equipped with a pair of flip plates that can clamp the cleaning cloth, and the sum of the maximum rotation radius of the pair of flip plates is not greater than the distance between the first and second rotation axis center lines, so that the pair of flip plates can rotate 360° without interfering with each other. When the outer surface of the cleaning cloth is dirty, the mop head can flip the pair of flip plates 360° to switch the cleaning cloth to the upper side of the pair of flip plates and expose the original inner surface to the outside, and then rotate the plate holder 180° to make the cleaning cloth face the ground, thereby completing the switching of the inner and outer surfaces of the cleaning cloth.

Specific embodiments
[0014] To describe in detail the technical content, structural features, achieved objectives and effects of the present application, the technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.
[0015] Hereinafter, the terms "first", "second", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first", "second", etc. may explicitly or implicitly include one or more of such features. In the description of the present application, unless otherwise specified, the meaning of "a plurality" is two or more.
[0016] In this application, spatial relative terms such as "under", "below", "beneath", "lower", "above", "upper", "on", "higher", "side" (e.g., as in "side wall") are used to describe the relationship of one element to another (other) element as shown in the drawings. The spatial relative terms are intended to include different orientations of the device in use, operation, and / or manufacture in addition to the orientation depicted in the drawings. For example, if the device in the drawings is flipped, an element described as "under" or "beneath" another element or feature will then be positioned "above" the other element or feature. Thus, the exemplary term "under" can include both upper and lower orientations. In addition, the device can be positioned otherwise (e.g., rotated 90 degrees or at other orientations), and accordingly, the spatial relative descriptors used herein are to be interpreted.
[0017] In this application, the term "free end" means the end portion of the flipping plate on the side away from the rotation center in the front-rear direction, and the term "rotating end" means the end portion of the flipping plate on the side close to the rotation center in the front-rear direction.
[0018] Referring to Figure 1-3 , the present invention provides a mop head 100 which can be attached to a long handle for use and perform a cleaning operation on the ground. As shown in the figure, the mop head 100 includes a mop bracket 1, a plate holder 2 rotatably connected to the mop bracket 1 (see Figure 5 ), a pair of flipping plates 3 which can respectively clamp the head and tail ends of the cleaning cloth 10, and a locking mechanism which can lock the pair of flipping plates 3 to the plate holder 2.
[0019] The mop bracket 1 includes a pair of side rods 11 opposite to each other left and right, a cross bar 12 extending left and right, and a connector 13 fixedly provided on the cross bar 12. The connector 13 is exposed externally and can be attached to a long handle. Each side rod 11 has a first end portion and a second end portion away from each other, and the left and right side end portions of the cross bar 12 are respectively connected to the first end portions of the pair of side rods 11. The cross bar 12 and the pair of side rods 11 jointly define an activity space (not marked in the figure) in which the plate holder 2 and the pair of flipping plates 3 can rotate freely.
[0020] The plate holder 2 provided in this embodiment is located inside the pair of side rods 11. The plate holder 2 is composed of a pair of holding plates 21 opposite to each other left and right. Each holding plate 21 is rotatably connected to the second end portion of the corresponding side rod 11. Further, the connection portion of each holding plate 21 and the corresponding side rod 11 is located in the middle of the holding plate 21. The connection line of the pair of connection portions passes through the center of gravity formed by the plate holder 2 and the pair of flipping plates 3 to improve the stability of the mop head 100.
[0021] A clamping part for clamping the cleaning cloth 10 is provided on each of the turning plates 3. The clamping part provided in this embodiment includes a groove extending in the left-right direction (not marked in the figure) and a cleaning cloth pressing strip 31 adapted to the groove. The user can clamp the head or tail of the cleaning cloth 10 through the cleaning cloth pressing strip 31 and the groove to fix the cleaning cloth 10 to the bottom of the mop head 100. It can be understood that in other embodiments, magnetic components, buckles and other structures can also be used to fix the cleaning cloth. On the premise that one side end of the cleaning cloth can be clamped or fixed, the specific structure of the above clamping part does not limit the protection scope of the present invention.
[0022] Further, to facilitate the user to disassemble and assemble the cleaning cloth 10, when the pair of turning plates 3 provided in this embodiment are locked to the plate holder 2, each clamping part is located at the outermost side of the corresponding turning plate 3.
[0023] A pair of turning plates 3 are arranged oppositely in the front-rear direction and are both located inside a pair of holding plates 21. The pair of turning plates 3 are respectively rotatably connected to the plate holder 2 around a first rotation axis Y1 extending in the left-right direction and a second rotation axis Y2 parallel to the first rotation axis Y1. Each of the holding plates 21 has a third end and a fourth end that are far away from each other. The first and second rotation axes respectively pass through the third ends and the fourth ends of the pair of holding plates 21. The pair of turning plates 3 are configured such that the sum of the maximum rotation radii r of the two is not greater than the distance between the first and second rotation axes, so that the pair of turning plates 3 can be flipped 360° without interfering with each other.
[0024] Reference Figure 3 and Figure 6 As shown in [relevant reference], after the pair of turning plates 3 are rotated 360° in opposite directions, the cleaning cloth 10 can be switched to the upper side of the pair of turning plates 3 and the original inner surface is exposed. However, the degree of stretching of the cleaning cloth 10 by the pair of clamping parts may change after flipping. Specifically, if the clamping part is provided on the lower surface of the corresponding turning plate 3, after the pair of turning plates 3 are rotated 360° in opposite directions, the cleaning cloth 10 is overstretched in a posture covering the upper surface and part of the lower surface of the pair of turning plates 3, which may cause the cleaning cloth 10 to fall off or be stretched and deformed and unable to be reused, etc.; if the clamping part is provided on the upper surface of the corresponding turning plate 3, after the pair of turning plates 3 are rotated 360° in opposite directions, there may be a situation where the cleaning cloth 10 cannot be tensioned and wrinkles appear on the surface. For this reason, when the pair of turning plates 3 provided in this embodiment are locked to the plate holder 2, the clamping part is located at the outermost side of the corresponding turning plate 3 and at the middle position of the corresponding turning plate 3 in the thickness direction, so as to ensure that the degree of stretching of the cleaning cloth 10 by the pair of clamping parts is basically the same before and after the inner and outer surfaces of the cleaning cloth 10 are switched.
[0025] Figure 4Another embodiment of the flip plate 3' is shown in the figure. To avoid redundancy, only the differences of the flip plate 3' are described below. When the flip plate 3' is locked on the plate holder 2', the rotating ends of a pair of flip plates 3' are located on the inner side of a pair of free ends, and the clamping parts are arranged on the free ends and exposed to the outside. The clamping parts are arranged in the middle position of the corresponding flip plate 3' in the thickness direction. Similarly, the pair of clamping parts 3' are constructed so that the sum of their maximum rotation radius r' is not greater than the distance between the first rotation axis centerline Y1' and the second rotation axis centerline Y2', so as to ensure that the pair of flip plates 3' can rotate 360° without interfering with each other.
[0026] Continue Reading Figure 1-2 , the locking mechanism provided in this embodiment includes a pair of locking units that can respectively lock a pair of flip plates 3 on the plate holder 2, and each locking unit includes a pair of locking grooves 41 opposite to each other on the left and right and a pair of movable latches (not shown in the figure) respectively adapted to the pair of locking grooves 41. Among them, one of the locking grooves 41 and the movable latch is configured on the plate holder 2, and the other is configured on the corresponding flip plate 3. It can be understood that in other embodiments, magnetic suction components, snap-fit structures, etc. can also be used to replace the pair of locking grooves and the pair of movable latches in this embodiment. Under the premise that a pair of flip plates can be locked to the plate holder, the specific form of the locking mechanism does not limit the protection scope of the present invention.
[0027] Furthermore, in order to facilitate the user to operate the locking mechanism, each locking unit of this embodiment also includes a pair of operating members 42 respectively connected to the pair of movable latches, an elastic member (not shown in the figure) for applying elastic force to the movable latches in the direction of the lock slot 41, and a pair of guide slots 43 for respectively guiding and limiting the operating member 42. Among them, the pair of movable latches are arranged on the flip plate 3 opposite to each other on the left and right; the operating member 42 is accommodated in the guide slot 43 and exposed to the outside from the upper side surface of the flip plate 3, and the operating member 42 is configured to be operated by a single finger of the user.
[0028] See Figure 3 and Figure 5-7 , the working principle of the mop head 100 is described below: when the mop head 100 is used to clean the floor, the cleaning cloth 10 is held on the lower surface of a pair of flip plates 3, and the outer surface of the cleaning cloth 10 contacts and cleans the floor (such as Figure 3 ). When the outer surface of the cleaning cloth 10 is dirty, the user can manipulate the operating members 42 on the pair of flip plates 3 to unlock the pair of flip plates 3, and move the pair of flip plates 3 in opposite directions (such as Figure 5 After the cleaning cloth 10 is flipped 360° in the R1 and R2 directions shown in , it is switched to the upper surface of a pair of flip plates 3 and the original inner surface is exposed to the outside (as shown in Figure 6 ). Thereafter, the user turns the plate holder 2 over by 180° (as Figure 7In the direction of R3 shown, the cleaning cloth 10 is oriented towards the ground, thereby completing the switching of the inner and outer surfaces of the cleaning cloth 10. Thus, the user can switch the inner and outer surfaces of the cleaning cloth 10 without contacting the cleaning cloth 10, reducing the cloth-changing operation and the frequency of the user contacting the cleaning cloth 10 during the cleaning operation, and further improving the cleaning efficiency.
[0029] The above embodiments are only for illustrating the technical concept and features of the present application, and their purpose is to enable those skilled in the art to understand the content of the present application and implement it accordingly, and shall not be used to limit the protection scope of the present application. Any equivalent changes or modifications made according to the spirit of the present application shall be covered within the protection scope of the present application.
