[0026] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Embodiment 1:

[0028] As Figure 1 and Figure 2 shown, this embodiment provides an electric suction negative pressure glass cleaning tool, which includes a housing, a negative pressure pump 3, a negative pressure suction cup 5, a wiping cotton 7, a scraping strip 15, a rotary connection assembly and a handrail rod 9. The negative pressure pump 3 is connected to the negative pressure suction cup 5. A through hole is provided on the bottom surface of the housing, and the negative pressure suction cup 5 extends to the outside of the housing through the through hole. A wiping cotton 7 is provided on the outer side of the bottom surface of the housing. The wiping cotton 7 is arranged around the negative pressure suction cup 5. The scraping strip 15 is provided on one side of the bottom surface of the housing. Specifically, the lower surface of the wiping cotton 7 is flush with the lower surface of the negative pressure suction cup 5. The top surface of the housing is connected to the handrail rod 9 through a rotary connection assembly. By setting the rotary connection assembly, the handrail rod 9 is convenient to rotate, and thus it is convenient to control the direction.

[0029] This embodiment also includes a plurality of rolling supports. A plurality of mounting holes are provided on the wiping cotton 7. One rolling support is arranged in one mounting hole, and the rolling support is connected to the bottom surface of the housing. The rolling support limits the negative pressure suction cup 5, the scraping strip 15 and the wiping cotton 7, preventing the wiping cotton 7 from being too severely squeezed by the negative pressure suction cup 5 with too strong suction force, resulting in the situation of being unable to wipe or being laborious. It is more labor-saving when in use.

[0030] This embodiment also includes a power source 6, a switch 10 and an air suction pipe 4. The power source 6 is used to supply power to the negative pressure pump 3. The switch 10 is arranged on the handrail rod 9. The switch 10 is used to control the opening and closing of the negative pressure pump 3. The negative pressure pump 3 is connected to the negative pressure suction cup 5 through the air suction pipe 4.

[0031] When cleaning the glass, press the switch 10 to turn on the negative pressure pump 3. The negative pressure pump 3 in this embodiment is an air suction pump, which is responsible for sucking out the air in the negative pressure suction cup 5. Through the negative pressure effect, the negative pressure suction cup 5, the wiping cotton 7 and the scraping strip 15 are adsorbed on the glass, so that the wiping cotton 7 and the scraping strip 15 squeeze and scrub the dust on the glass, making the decontamination effect better. Specifically, after the moisture in the wiping cotton 7 moistens the dust on the glass surface, the scraping strip 15 scrapes off the stains wiped by the wiping cotton 7, realizing wiping and scraping immediately, not easy to pinch hands and damage the glass. After use, press the switch 10 to turn off the negative pressure pump 3, and then the electric suction negative pressure glass cleaning tool can be removed from the glass surface.

[0032] Specifically, the housing includes an upper cover plate 1 and a lower housing 2. The upper cover plate 1 is snap-connected to the lower housing 2. The negative pressure pump 3 and the power supply 6 are fixed to the lower surface of the upper cover plate 1. Through holes are provided on the bottom surface of the lower housing 2, and the scraping strip 15 is arranged on one side of the bottom surface of the lower housing 2.

[0033] In this specific embodiment, the cross-section of the housing is triangular. A clamping block is provided at the upper part of each of the three edges of the lower housing 2, and a clamping groove is provided on the lower surface of each of the three edges of the upper cover plate 1. A clamping groove corresponds to a clamping block in position and is matched in structure, thereby realizing the snap connection between the upper cover plate 1 and the lower housing 2. In addition, the cross-sectional shape of the housing is not limited to triangular, and the cross-sectional shape of the housing can also be set as rectangular, trapezoidal, etc.

[0034] In this specific embodiment, the rotary connection assembly includes a U-shaped fixing block 12, a connection block 13, a first pin shaft and a second pin shaft 14. The U-shaped fixing block 12 is fixed to the upper surface of the upper cover plate 1. The connection block 13 is rotatably connected to the U-shaped fixing block 12 through the first pin shaft, so that the connection block 13 can swing back and forth relative to the U-shaped fixing block 12. The handrail rod 9 is rotatably connected to the connection block 13 through the second pin shaft 14, so that the handrail rod 9 can swing left and right relative to the connection block 13. The first pin shaft and the second pin shaft 14 are perpendicular to each other. By adopting the rotary connection assembly in this embodiment, the handrail rod 9 can swing back and forth and left and right relative to the housing, making the handrail rod 9 rotate flexibly and facilitating controlling the direction by rotating the handrail rod 9 when wiping the glass.

[0035] In this specific embodiment, as Figure 3As shown in the figure, the rolling support member includes a mounting shell 16, a ball 8, and a plurality of steel balls 17. The mounting shell 16 is provided with an opening. The plurality of steel balls 17 are arranged in the mounting shell 16. The ball 8 is clamped at the opening, and the ball 8 can rotate relative to the mounting shell 16. A plurality of mounting grooves are provided on the bottom surface of the lower housing 2. One mounting groove corresponds to one mounting hole in position. One mounting shell 16 is fixed in one mounting groove. The ball 8 is recessed inward relative to the wiping cotton 7. During use, the wiping cotton 7 is squeezed so that the ball 8 contacts the glass. The ball 8 rolls, thereby reducing the frictional force between the electric suction negative pressure type glass wiping tool and the glass surface during use, making it more labor-saving during wiping.

[0036] In another embodiment, the rolling support member is a runner. One runner is arranged in one mounting hole. The upper end of the runner is mounted on the bottom surface of the lower housing 2. The runner is recessed inward relative to the wiping cotton 7. Similarly, the wiping cotton 7 is squeezed so that the runner contacts the glass. The runner rolls, thereby reducing the frictional force between the electric suction negative pressure type glass wiping tool and the glass surface during use, making it more labor-saving during wiping.

[0037] In this specific embodiment, as Figure 1 shown, three rolling support members are provided. The three rolling support members are respectively arranged near the three corners of the bottom surface of the triangular lower housing 2.

[0038] Specifically, the negative pressure pump 3 is connected to the power source 6. A switch 10 is provided between the negative pressure pump 3 and the power source 6. By pressing the switch 10, the connection and disconnection between the power source 6 and the negative pressure pump 3 are realized, thereby controlling the opening and closing of the negative pressure pump 3.

[0039] To facilitate the user's grasping, in this embodiment, an extension rod 11 is further included. The extension rod 11 is connected to the upper part of the handrail rod 9. The extension rod 11 and the handrail rod 9 form a handheld rod. Specifically, the extension rod 11 is sleeved on the outside of the upper part of the handrail rod 9. The extension rod 11 and the handrail rod 9 are locked by screws. By adjusting the relative position between the extension rod 11 and the handrail rod 9, the length of the handheld rod can be adjusted, thereby better meeting the needs of the user. It should be noted that the negative pressure pump 3 and the power source 6 are not limited to being installed in the housing, and can also be installed on the handrail rod 9 or the extension rod 11.

[0041] As Figure 4As shown in the figure, this embodiment provides an electric suction negative pressure glass cleaning tool. The rotary connection assembly includes a mounting table 18, a rotating connecting member 19, a U-shaped rotating block 20, and a third pin shaft. The mounting table 18 is arranged on the upper surface of the upper cover plate 1. A cylindrical hole is provided on the mounting table 18, and the lower end of the cylindrical hole penetrates through the upper cover plate 1. The rotating connecting member 19 is installed in the cylindrical hole. The rotating connecting member 19 can rotate relative to the mounting table 18, and the axial position of the rotating connecting member 19 remains unchanged. The U-shaped rotating block 20 is fixed to the upper end of the rotating connecting member 19. The handrail rod 9 is rotationally connected to the U-shaped rotating block 20 through the third pin shaft. The third pin shaft is arranged parallel to the upper cover plate 1. The U-shaped rotating block 20 can rotate relative to the mounting table 18, and the handrail rod 9 can swing back and forth relative to the U-shaped rotating block 20. That is, the rotary connection assembly in this embodiment is used to realize the arbitrary rotation and back-and-forth swing of the handrail rod 9 relative to the housing, making the handrail rod 9 rotate flexibly and facilitating the control of the direction by rotating the handrail rod 9 when wiping the glass.

[0042] As Figure 5 shown, the rotating connecting member 19 includes a circular sleeve 191 and an annular clamping platform 192 arranged at the lower end of the circular sleeve 191. The outer diameter of the annular clamping platform 192 is larger than the diameter of the cylindrical hole. Two vertical openings are provided in the upper part of the circular sleeve 191, and a spring buckle 193 is installed on each vertical opening. During use, the rotating connecting member 19 is installed from the lower end of the cylindrical hole, so that the annular clamping platform 192 of the rotating connecting member 19 contacts the lower surface of the upper cover plate 1, and the two spring buckles 193 extend out from the upper end of the cylindrical hole and are clamped on the upper surface of the mounting table 18. At this time, the rotating connecting member 19 can rotate relative to the mounting table 18, and the axial position of the rotating connecting member 19 remains unchanged by the upper limit of the two spring buckles 193 and the lower limit of the annular clamping platform 192.
