Detailed Description of the Invention

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Embodiment 1:

[0022] As Figures 1 - 8 shown, a rotating device of a handheld floor cleaning device provided by the present utility model includes a floor mop bottom cover 1 and a floor mop upper shell 2. The floor mop bottom cover 1 is fixedly covered on the floor mop upper shell 2 to form a floor mop housing 3. A swivel joint 4 is movably installed on the floor mop housing 3. The swivel joint 4 includes a horizontal axis 5 and a vertical axis 6. The floor mop bottom cover 1 is provided with a positioning groove 7. The positioning groove 7 elastically abuts against a top block 9 through a spring 8. The top block 9 elastically abuts against the horizontal axis 5. The swivel joint 4 is movably connected to an upper body cover 10 and a shaft card 11. The horizontal axis 5 is provided with a shaft hook 12. The vertical axis 6 is provided with a first semi-circular stop edge 13. The upper body cover 10 is provided with a second semi-circular stop edge 14. The floor mop upper shell 2 is provided with a limiting convex block 15. The shaft card 11 extends with a convex piece 16. The upper body cover 10 is fixedly connected to the convex piece 16 by a first hook 17. The top block 9 is provided with a second hook 18.

[0023] Through the above technical solution, the swivel joint 4 of the present invention includes a horizontal axis 5 and a vertical axis 6. The horizontal axis 5 and the vertical axis 6 are arranged perpendicular to each other. The floor mop housing 3 is movably connected to the horizontal axis 5 of the swivel joint 4, so that the vertical axis 6 of the swivel joint 4 can be turned up and down around the floor mop housing 3. The vertical axis 6 is movably connected to an upper body cover 10. The upper body cover 10 is used for fixedly connecting the handheld rod of the floor washer, so that the handheld rod can rotate around the vertical axis 6. By movably connecting the horizontal axis 5 of the swivel joint 4 with the floor mop mechanism, the connection firmness between the swivel joint 4 and the floor mop mechanism is improved. The vertical axis 6 and the horizontal axis 5 are an integrally formed structure. The vertical axis 6 is connected to the handheld rod through the upper body cover 10, ensuring the reliability of the connection between the handheld rod and the floor mop mechanism and improving the service life of the present invention.

[0024] Embodiment 2:

[0025] As Figures 1 - 8 shown, the present utility model includes a floor mop bottom cover and a floor mop upper shell. The floor mop bottom cover is fixedly covered on the floor mop upper shell to form a closed floor mop housing 3. A swivel joint 4 is installed inside the floor mop housing 3. The swivel joint 4 has a horizontal axis 5 and a vertical axis 6. The horizontal axis 5 and the vertical axis 6 are arranged at a right angle. Among them, the horizontal axis 5 is movably connected to the floor mop housing 3, and the vertical axis 6 is movably connected to the handheld rod of the floor washer. The handheld rod can swing up and down around the horizontal axis 5 and can also rotate around the vertical axis 6. Through the configuration of these two axes, the rotation angle between the floor mop mechanism and the handheld rod can be flexibly adjusted to adapt to different cleaning angles and postures.

[0026] A positioning groove 7 is provided on the bottom cover of the floor mopping housing 3, and this positioning groove 7 contacts the top block 9 through a spring 8. The top block 9 abuts against the cross shaft 5 under the elastic action of the spring 8. A rotating shaft hook 12 is provided on the cross shaft 5, and a limiting convex block 15 is provided on the upper floor mopping housing 2. In the initial state of the hand-held rod, the rotating shaft card 11 is clamped on the limiting convex block 15 to play a role in temporarily fixing the hand-held rod. When using the floor washing machine, by pressing down the hand-held rod, the cross shaft 5 presses down the top block 9. At this time, the rotating shaft card 11 disengages from the limiting convex block 15, enabling the hand-held rod to swing up and down.

[0027] A second semi-circular retaining edge 14 is provided on the upper body cover 10. The second semi-circular retaining edge 14 cooperates with the rotating shaft card 11 to form a closed retaining ring. A first semi-circular retaining edge 13 is provided on the longitudinal shaft 6. During the rotation of the hand-held rod, the first semi-circular retaining edge 13 always rotates within the closed retaining ring, enabling the adapter 4 to form a reliable connection with the upper body cover 10. When the upper body cover 10 is rotated, the rotating shaft card 11 will also rotate accordingly. A lug 16 extends from the rotating shaft card 11. At this time, after the rotating shaft card 11 rotates to a certain angle, the first semi-circular retaining edge 13 and the lug 16 block each other, thereby restricting the rotation range of the longitudinal shaft 6.

[0028] In practical applications, the structure of this rotating device enables the floor mopping mechanism to adjust the angle as needed during the cleaning process to adapt to different cleaning areas. The up-and-down swing of the hand-held rod around the cross shaft 5 can enable the floor mopping mechanism to maintain a certain angle during cleaning, while the rotation around the longitudinal shaft 6 can change the cleaning direction. Through this rotating device, users can operate the hand-held floor washing machine more flexibly and improve the cleaning efficiency.

[0029] The upper shell of the floor mop of the present utility model is provided with a limiting bump 15. In addition to cooperating with the rotating shaft card 11 to temporarily fix the hand-held rod, the limiting bump 15 also has a limiting function. The limiting bump 15 is located close to the horizontal shaft 5 and is used in cooperation with the rotating shaft hook 12 on the horizontal shaft 5. The main function of the limiting bump 15 is to limit the rotation range of the horizontal shaft 5, thereby controlling the rotation angle that the floor mop mechanism can reach during the cleaning process. Specifically, the horizontal shaft 5 will be physically restricted by the limiting bump 15 during its rotation. When the horizontal shaft 5 rotates to a certain angle, the rotating shaft hook 12 will contact the limiting bump 15, thereby preventing the horizontal shaft 5 from continuing to rotate. In this way, the limiting bump 15 ensures that the rotation angle of the horizontal shaft 5 will not exceed the preset range, thus avoiding excessive rotation or out-of-control phenomena that may occur during the operation of the device. The design of this limiting bump 15 enables the hand-held floor cleaning device to maintain stability during various cleaning tasks and ensures the accuracy of operation. The cooperation between the limiting bump 15 and the rotating shaft hook 12 can effectively limit the movement range of the horizontal shaft 5 and prevent the horizontal shaft 5 from rotating excessively accidentally during the operation. This limitation not only increases the operation safety of the device but also enhances the user's sense of control during the actual cleaning process, enabling the device to maintain a stable working state when cleaning various floors. In addition, the presence of the limiting bump 15 also has the role of a protection device. By limiting the rotation range of the horizontal shaft 5, damage to the internal structure of the device caused by excessive rotation is avoided. This protection mechanism can extend the service life of the device and reduce the risk of failures or damages caused by excessive rotation. The setting of the limiting bump 15 and the cooperation with the rotating shaft hook 12 can control the rotation angle of the horizontal shaft 5, ensuring the stability and safety of the hand-held floor cleaning device during actual use. In this way, users can operate the device more reassuringly and carry out efficient and safe floor cleaning operations.

[0030] A lug 16 extends from the rotating shaft card 11 of the present utility model. The function of this lug 16 is to cooperate with the first hook 17 of the upper body cover 10 to ensure the stability of the rotating shaft card 11 in the rotating device. Specifically, the upper body cover 10 is mutually clamped with the lug 16 through the first hook 17, thereby realizing the fixation of the lug 16. Through the clamping of the first hook 17, a firm connection is formed between the lug 16 and the upper body cover 10, thereby preventing the lug 16 from separating from the upper body cover 10 during the operation of the device. During the operation of the device, the clamping force of the first hook 17 on the lug 16 ensures that the lug 16 will not separate due to vibrations or other external forces during operation, thereby maintaining the stability and reliability of the entire rotating device. The importance of this fixation mechanism lies in that it ensures the stable operation of each component of the rotating device during the cleaning process. Due to the fixed connection between the lug 16 and the upper body cover 10, each part of the rotating device can operate normally according to the designed movement trajectory, avoiding functional failures caused by component loosening or detachment. This design improves the reliability of the device while ensuring the safety of users during use.

[0031] The top block 9 of the present utility model is provided with a second hook 18, which plays an important role during the assembly of the device. The top block 9 is connected to the positioning groove 7 through a spring 8. The elasticity of the spring 8 causes the top block 9 to be ejected during assembly, so it is necessary to fix the top block 9 in the positioning groove 7 through the second hook 18. The core purpose of this design is to prevent the top block 9 from being ejected due to the elastic force of the spring 8 during assembly or use, thereby ensuring that the top block 9 can be firmly held in its predetermined position. Specifically, when the top block 9 is ejected by the spring 8, the function of the second hook 18 is to firmly clamp the top block 9 in the positioning groove 7. The second hook 18 forms a firm locking mechanism with the top block 9 through its structure, keeping the top block 9 stable in the positioning groove 7 and preventing it from detaching due to the elastic action of the spring 8. This fixing method ensures that the top block 9 can be reliably pressed down in the positioning groove 7, thereby avoiding the detachment problem of the top block 9 caused by the reaction force of the spring 8.
