Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0034] The present application proposes a handheld cleaning device, which may be a handheld mopping robot, a handheld floor washing robot or a handheld integrated washing and mopping machine, which is not specifically limited here. Figures 1 to 5 In the embodiment of the present application, the handheld cleaning device includes a cleaning base 10 , a rotating head 20 and a body 30 .

[0035] The cleaning base 10 is used to clean the work surface, and the cleaning base 10 is provided with a first limiting structure 111 and a second limiting structure 121. The work surface refers to a plane on which the handheld cleaning device can perform cleaning work, such as: the ground, the wall, the desktop, etc., wherein the cleaning base 10 is of many types, and the cleaning base 10 may include a roller brush, and the cleaning base 10 may also include a roller, which is not specifically limited here. It should be noted that the cleaning base 10 should be adapted to different shapes according to different types of cleaning tools.

[0036] The rotating head 20 is provided with a first mounting portion 21 and a second mounting portion 22, the first mounting portion 21 is rotatably connected to the cleaning base 10, and the second mounting portion 22 is rotatably connected to the body 30, wherein the body 30 rotates around a first axis Y relative to the rotating head 20, and the rotating head 20 rotates around a second axis X relative to the cleaning base 10, and the second axis X is arranged perpendicular to the first axis Y.

[0037] There are many ways to set the rotating head 20. In some ways, the first mounting portion 21 and the second mounting portion 22 of the rotating head 20 are rotatably connected to the cleaning base 10 and the body 30 through bearings, respectively. In another way, the first mounting portion 21 and the second mounting portion 22 of the rotating head 20 are slidably connected to the cleaning base 10 and the body 30, respectively. Specifically, in this embodiment, the first mounting portion 21 and the second mounting portion 22 are both cylindrical as a whole, and the axis of the first mounting portion 21 is perpendicular to the axis of the second mounting portion 22.

[0038] The body 30 is indirectly connected to the cleaning base 10 through the rotating head 20. When the body 30 rotates relative to the rotating head 20, the body 30 also rotates relative to the cleaning base 10. When the rotating head 20 rotates relative to the cleaning base 10, the body 30 connected to the rotating head 20 also rotates relative to the cleaning base 10, that is, the body 30 can be turned over and rotated relative to the cleaning base 10. In this way, a user using the handheld cleaning device can operate the cleaning base 10 by holding the handle on the body 30, so as to clean the work surface.

[0039] It is understandable that the handheld cleaning device has an in-use state and a non-use state. The in-use state means that the user uses the handheld cleaning device to perform cleaning work, and the non-use state means that the handheld cleaning device is not used and is stored in a designated space, so that the handheld cleaning device is idle. When the handheld cleaning device is in the in-use state, the user can operate the cleaning base 10 by holding the handle on the body 30; when the handheld cleaning device is in the non-use state, the body 30 is usually flipped to an upright state relative to the cleaning base 10 for easy storage.

[0040] When the body 30 is in an upright state relative to the cleaning base 10 , the first limiting structure 111 cooperates with the rotating head 20 to limit the rotation of the rotating head 20 relative to the cleaning base 10 , and the second limiting structure 121 cooperates with the body 30 to limit the rotation of the body 30 relative to the rotating head 20 .

[0041] Through the above technical solution, the cleaning base 10 is provided with a first limiting structure 111 and a second limiting structure 121, and the rotating head 20 is provided with a first mounting portion 21 and a second mounting portion 22. The first mounting portion 21 is rotatably connected to the cleaning base 10, and the second mounting portion 22 is rotatably connected to the body 30. When the body 30 is in an upright state relative to the cleaning base 10, the first limiting structure 111 cooperates with the rotating head 20 to limit the rotation of the rotating head 20 relative to the cleaning base 10, and the second limiting structure 121 cooperates with the body 30 to limit the rotation of the body 30 relative to the rotating head 20. With such a configuration, when the handheld cleaning device needs to be used, the user can flip and rotate the body 30 relative to the cleaning base 10, so as to operate the cleaning base 10 through the handle on the body 30 to achieve cleaning work. When the handheld cleaning device is not needed, the body 30 can be flipped to an upright state relative to the cleaning base 10. At this time, the first limiting structure 111 cooperates with the rotating head 20 to limit the rotation of the rotating head 20 relative to the cleaning base 10, so that the body 30 connected to the rotating head 20 cannot be flipped relative to the cleaning base 10. At the same time, due to The body 30 cannot flip over relative to the cleaning base 10, so the body 30 connected to the rotating head 20 can cooperate with the second limiting structure 121, and the second limiting structure 121 cooperates with the body 30 to limit the rotation of the body 30 relative to the rotating head 20, so that the body 30 cannot rotate relative to the cleaning base 10. In this way, when the body 30 is in an upright state relative to the cleaning base 10, the body 30 is not easy to flip, rotate, shake, etc., and can maintain relative stability, thereby reducing the possibility of the body 30 tipping over, thereby reducing the safety hazard caused by the unstable center of gravity of the body 30.

[0042] In some examples, such as Figure 3 and Figure 4 As shown, the rotating head 20 is provided with a first matching portion 23, and the first limiting structure 111 includes a limiting pin 112 and an elastic member 113. The limiting pin 112 is movably mounted on the cleaning base 10, and the elastic member 113 provides an elastic force to drive the limiting pin 112 to limit the first matching portion 23, so as to limit the rotation of the rotating head 20 relative to the cleaning base 10 under the action of gravity.

[0043] There are many forms of limiting the first matching portion 23 by the limiting pin 112. In one setting form, the first matching portion 23 is a cam, and the limiting pin 112 can slide and abut against the circumference of the cam. When the handheld cleaning device is not in use, the elastic member 113 provides an elastic force to drive the limiting pin 112 to limit the cam, so as to limit the rotation of the cam, thereby limiting the rotation of the rotating head 20 relative to the cleaning base 10 under the action of gravity. In another setting form, the first matching portion 23 is a limiting groove. When the handheld cleaning device is not in use, the elastic member 113 provides an elastic force to drive the limiting pin 112 to engage with the limiting groove, so as to lock the limiting pin 112 with the limiting groove, thereby limiting the rotation of the rotating head 20 relative to the cleaning base 10 under the action of gravity.

[0044] There are many ways to movably mount the stop pin 112 on the cleaning base 10. In one arrangement, the elastic member 113 is a spring, and the stop pin 112 is directly and movably mounted on the cleaning base 10 through the spring, that is, one end of the spring is fixedly mounted on the cleaning base 10, and the other end of the spring is fixedly connected to the stop pin 112, and the elastic member 113 can also be a spring. In another form, the cleaning base 10 is concavely or convexly provided with a mounting seat, and the mounting seat is formed with a groove, and the stop pin 112 is slidably mounted in the groove, and the elastic member 113 is elastically mounted between the stop pin 112 and the bottom wall of the groove, and the elastic member 113 can be an elastic ball, a spring, etc.

[0045] In this way, when the handheld cleaning device is not in use, the elastic member 113 provides an elastic force to drive the limit pin 112 to limit the first matching portion 23, so as to limit the rotation of the rotating head 20 relative to the cleaning base 10 under the action of gravity, so that the body 30 connected to the rotating head 20 cannot be flipped relative to the cleaning base 10, so as to keep the body 30 upright.

[0046] In some examples, such as Figure 3 and Figure 4 As shown, the rotating head 20 is provided with a cam to form a first matching portion 23, and the circumferential side of the cam can slidably abut against the limiting pin 112, so that when the rotating head 20 rotates relative to the cleaning base 10 under the action of external force, the limiting pin 112 is squeezed to release the limiting of the first matching portion 23.

[0047] Specifically, the cam is formed on the first mounting portion 21 or adjacent to the first mounting portion 21 , so that the peripheral side of the cam can slidably abut against the limiting pin 112 .

[0048] With such arrangement, when the rotating head 20 is rotated relative to the cleaning base 10 by an external force, that is, the rotating head 20 is driven by the body 30 to rotate relative to the cleaning base 10, the rotating head 20 will drive the cam to rotate. During the rotation of the cam, the circumferential side of the cam will slide relative to the limit pin 112, thereby squeezing the limit pin 112. The limit pin 112 can then release the limit on the first matching portion 23. The user can easily switch the handheld cleaning device from a non-use state to a use state by manually turning the handle on the body 30.

[0049] In some examples, the rotating head is recessed with a limiting groove to form a first matching portion 23, and the limiting pin 112 is plugged into the limiting groove. The limiting groove is provided with arc guide surfaces on both sides of the rotation direction of the rotating head 20, so that when the rotating head 20 rotates relative to the cleaning base 10 under the action of external force, the limiting pin 112 is squeezed to release the limitation of the first matching portion 23.

[0050] Likewise, the limiting groove is formed on the first mounting portion 21 or adjacent to the first mounting portion 21 , so that the limiting groove and the limiting pin 112 can be plugged and matched.

[0051] With such arrangement, when the rotating head 20 is rotated relative to the cleaning base 10 by an external force, that is, the rotating head 20 is driven by the body 30 to rotate relative to the cleaning base 10, the rotating head 20 will drive the limiting groove to rotate. During the rotation of the limiting groove, the arc guide surface on one side of the limiting groove will slide relative to the limiting pin 112, thereby squeezing the limiting pin 112, and the limiting pin 112 can release the limitation on the first matching part 23. The user can easily switch the handheld cleaning device from a non-use state to a use state by manually turning the handle on the body 30. Compared with the above-mentioned cam solution, the limit pin 112 and the limit groove are more stably plugged into each other in this solution, so as to improve the stability of the body 30 when it is in an upright state relative to the cleaning base 10.

[0052] Considering that the limiting pin 112 and the first matching part 23 slide relative to each other during the process of squeezing the limiting pin 112 to release the limiting of the first matching part 23, the end of the limiting pin 112 that contacts the first matching part 23 is hemispherical to facilitate the relative sliding of the limiting pin 112 and the first matching part 23.

[0053] In some examples, such as Figures 3 to 7As shown, the cleaning base is provided with a receiving groove 13, a limit pin 112 is slidably installed in the receiving groove 13, and an elastic member 113 is elastically supported between the limit pin 112 and the bottom of the receiving groove 13 to drive the limit pin 112 to always have a movement tendency from the receiving groove 13 to the notch of the receiving groove 13, and the first limit structure 111 also includes a cover plate 114, which is installed on the cleaning base and covers part of the notch of the receiving groove 13 to limit the limit pin 112 from being separated from the receiving groove 13.

[0054] There are various ways to slide the limit pin 112 in the receiving groove 13. In one arrangement, a guide rail is provided in the receiving groove 13, and the limit pin 112 can slide along the guide rail. In another arrangement, the limit pin 112 slides against at least two groove walls of the receiving groove 13.

[0055] With such a configuration, when the handheld cleaning device is in a non-use state, the elastic member 113 can stably provide elastic force to drive the limit pin 112 to limit the first matching portion 23. When the handheld cleaning device is switched from a non-use state to a use state, the matching portion can stably squeeze the limit pin 112, and the limit pin 112 is not easy to move during the activity, so as to improve the reliability of the first limit structure 111.

[0056] In some examples, such as Figure 4 As shown, two threaded holes 14 are respectively provided on opposite sides of the slot of the receiving slot 13, and the cover plate 114 is threadedly connected to the two threaded holes 14 through a screw structure. The cover plate 114 covers the slot of the receiving slot 13, and the cover plate 114 is provided with a through hole connected to the receiving slot 13, wherein the aperture of the through hole is smaller than the aperture of the slot of the receiving slot 13.

[0057] Such a configuration facilitates the installation and removal of the limit pin 112 , so that a new limit pin 112 can be replaced when the limit pin 112 is excessively worn, thereby ensuring the normal operation of the first limit structure 111 and improving the assembly efficiency of the first limit pin 112 .

[0058] In order to further improve the stability of the body 30 when it is in an upright state relative to the cleaning base 10 , the number of the first limiting structures 111 may be more than two.

[0059] In some examples, such as Figure 4 As shown, the first limiting structure 111 includes an elastic protrusion, the rotating head 20 is recessed with a slide groove, the slide groove is provided with arc guide surfaces on both sides of the rotating direction of the rotating head 20, and the elastic protrusion is plugged into and matched with the slide groove.

[0060] With such a configuration, when the handheld cleaning device is switched between the use state and the non-use state, the elastic protrusion can be squeezed by the arc guide surface, and the elastic protrusion undergoes plastic deformation. When the elastic protrusion enters the slide groove or moves away from the slide groove, the elastic protrusion restores its original shape. When the elastic protrusion is plugged into the slide groove, the rotation of the rotating head 20 is restricted, so as to restrict the rotation of the rotating head 20 relative to the cleaning base 10 under the action of gravity.

[0061] In some examples, such as Figure 1 , Figure 2 and Figure 7 As shown, the cleaning base 10 is concavely provided with a positioning groove to form a second limiting structure 121, and the body 30 is convexly provided with a positioning block 31, and the positioning block 31 is plugged and matched with the positioning groove.

[0062] Specifically, the positioning block 31 is located at one end where the body 30 is connected to the rotating head 20 . When the handheld cleaning device is in use, the positioning block 31 is adjacent to the cleaning base 10 .

[0063] With such arrangement, when the body 30 is in an upright state relative to the cleaning base 10, the positioning block 31 is plugged into and matched with the positioning groove, so that the rotation of the body 30 relative to the rotating head 20 can be limited, thereby limiting the rotation of the body 30 relative to the cleaning base 10, so as to ensure the stability of the body 30. When the handheld cleaning device is in use, the body 30 can be flipped over so that the positioning block 31 can be quickly disengaged from the positioning groove.

[0064] In some examples, such as Figure 6 and Figure 7 As shown, the cleaning base 10 includes a floor brush 11 and a shell 12, the first mounting portion 21 is rotatably connected to the floor brush 11 and / or the shell 12, the shell 12 is detachably connected to the floor brush 11, and is arranged around the circumference of the second mounting portion 22 of the rotating head 20, and a positioning groove is formed on the inner side of the shell 12.

[0065] In one configuration, circular holes are respectively provided on two opposite sides of the enclosure 12 for rotational connection of the first rotational mounting portion, wherein the positioning groove is located on one side of a line connecting the two circular holes.

[0066] With such a configuration, the rotating head 20 can be protected by the casing 12 to protect the connection between the body 30 and the cleaning base 10 , and the assembly efficiency of the handheld cleaning device can be improved.

[0067] In some examples, such as Figure 6 and Figure 7As shown, the side of the casing 12 away from the positioning groove is lower than the side of the positioning groove in vertical height, so as to form a relief portion for avoiding the movement of the rotating head 20 relative to the floor brush 11. In this way, the range of movement of the body 30 relative to the cleaning base 10 can be increased to improve the flexibility of the handheld cleaning device, thereby improving the user's operating experience of the handheld cleaning device.

[0068] The above description is only an optional embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural transformations made by using the contents of the present application specification and drawings under the inventive concept of the present application, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present application.
