Description

Technical Field

[0001] This utility model belongs to the technical field of glass cleaning machines, specifically a glass cleaning machine. Background Technology

[0002] A glass washing machine is a device that sprays or splashes water onto the glass, then uses a rubber squeegee to scrape the glass while simultaneously using an internal negative pressure device to suck away the water. Some glass washing machines have the function of spraying cleaning fluid, while others do not.

[0003] For example, CN204797739U discloses a glass cleaner that is divided into two channels by a partition on the brush head. The upper channel is connected to a fan, and the lower channel is connected to a water tank for water-air separation. If the glass cleaner is not used upright, water may enter from the upper channel, and the fan is too far from the scraper, resulting in insufficient suction. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing a glass washing machine that effectively prevents water from entering through the suction channel and significantly improves suction power.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a glass cleaning machine, comprising a cleaning machine body, an exhaust port, a cleaning head and a water tank, a water-air separation shell inside the cleaning machine body, the water-air separation shell including a main shell, a connecting neck at the top of the main shell communicating with the cleaning head through an internal channel, an extension channel extending into the main shell from the bottom of the connecting neck, a through hole at the bottom of the main shell through which a fan draws air from the main shell to the outside, a water-blocking ring extending upward into the main shell circumferentially arranged around the through hole, the top of the water-blocking ring being higher than the bottom of the extension channel, and a water outlet at the bottom of the main shell near the connecting neck, the water outlet being connected to the water tank. This glass washer uses a fan to draw air from the through-hole to the outside of the main housing and discharge it from the exhaust port, creating a negative pressure inside the main housing. This allows water and air to be drawn into the suction port on the cleaning head. When water flows into the main housing, it is guided by the extension channel and flows directly into the water tank from the outlet. Air can flow back from the bottom of the extension channel and then flow out from the top of the baffle ring through the through-hole. This structure effectively prevents water from entering through the air intake channel, and the closer distance between the fan and the cleaning head effectively increases the suction power at the same power.

[0006] In the above technical solution, preferably, when the main body of the cleaning machine is placed horizontally, the bottom of the main housing slopes downwards towards the water outlet. This structure makes it difficult for the sucked-in water to remain inside the main housing, allowing it to quickly enter the water tank.

[0007] In the above technical solution, preferably, the bottom of the main housing is recessed to form a fan blade mounting cavity, a fan is fixed inside the main body of the cleaning machine, the fan blades are located inside the fan blade mounting cavity, and the through hole is located at the top of the fan blade mounting cavity. This structure allows the fan blades to be closer to the main housing, thereby increasing the air pressure.

[0008] In the above technical solution, preferably, a convex ring for inserting into the outlet is provided on the inlet side of the top of the water tank.

[0009] In the above technical solution, preferably, the water tank is detachably connected to the main body of the cleaning machine. The bottom of the water tank has a fastening groove for engaging with an elastic buckle on the main body of the cleaning machine. The bottom of the main body of the cleaning machine has an elastic buckle mounting groove, in which an elastic buckle is hinged. A spring is provided between the end of the elastic buckle furthest from the water tank and the main body of the cleaning machine. This structure allows for easy assembly and disassembly of the water tank, facilitating water emptying and cleaning.

[0010] In the above technical solution, preferably, the water inlet of the water tank is provided with an extension pipe extending into the middle or bottom of the water tank. This structure ensures that when the glass washing machine rotates and swings, or even when inverted, water is difficult to flow back from the water tank into the main casing due to the obstruction of the extension pipe.

[0011] In the above technical solution, preferably, the outer wall of the convex ring is provided with an annular groove, and a sealing ring is fitted onto the annular groove. This structure is used to increase the sealing between the water tank and the outlet, preventing leakage.

[0012] Compared with the prior art, this utility model has the following advantages: This glass cleaning machine uses a fan to draw air from the through hole to the outside of the main housing and discharge it from the exhaust hole, creating a negative pressure inside the main housing. This allows water and gas to be drawn into the suction hole on the cleaning head. When water flows into the main housing, it is guided by the extension channel and flows directly into the water tank from the outlet. The gas can flow back from the bottom of the extension channel and then flow out from the top of the water baffle ring through the through hole. This structure can effectively prevent water from entering through the air intake channel, and the distance between the fan and the cleaning head is closer, which can effectively improve the suction power under the same power.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments: See below Figures 1 to 5 A glass cleaning machine includes a cleaning machine body 1, an exhaust port 2 on the cleaning machine body 1, a cleaning head 3 and a water tank 4 on the cleaning machine body 1, a water-air separation shell inside the cleaning machine body 1, the water-air separation shell including a main shell 5, a connecting neck 6 at the top of the main shell 5 communicating with the cleaning head 3 through an internal channel, an extension channel 7 extending into the main shell 5 from the bottom of the connecting neck 6, a through hole 8 at the bottom of the main shell 5, a fan drawing air from the through hole 8 to the outside of the main shell 5, a water baffle ring 9 extending upward into the main shell 5 around the through hole 8, the top of the water baffle ring 9 being higher than the bottom of the extension channel 7, and a water outlet 10 at the bottom of the main shell 5 near the connecting neck 6, the water outlet 10 being connected to the water tank 4. This glass washer uses a fan to draw air from the through hole 8 to the outside of the main housing 5 and discharge it from the exhaust hole 2, creating a negative pressure inside the main housing 5. This allows water and gas to be drawn into the suction hole on the cleaning head 3. When water flows into the main housing 5, it is guided by the extension channel 7 and flows directly into the water tank 4 from the outlet 10. The gas can flow back from the bottom of the extension channel 7 and then flow out from the top of the water baffle ring 9 through the through hole 8. This structure can effectively prevent water from entering through the air intake channel, and the distance between the fan and the cleaning head 3 is closer, which can effectively improve the suction power under the same power.

[0019] In this embodiment, when the main body 1 of the cleaning machine is placed horizontally, the bottom of the main housing 5 tilts downwards towards the water outlet 10. This structure makes it difficult for the sucked-in water to remain inside the main housing 5, allowing it to quickly enter the water tank 4.

[0020] In this embodiment, the bottom of the main housing 5 is recessed to form a fan blade mounting cavity 11. A fan 12 is fixed inside the main body 1 of the cleaning machine, and the fan blades of the fan 12 are located inside the fan blade mounting cavity 11. The through hole 8 is located at the top of the fan blade mounting cavity 11. This structure allows the fan blades to be closer to the main housing 5, thereby increasing the air pressure.

[0021] In this embodiment, the water tank 4 is detachably connected to the main body 1 of the cleaning machine. A protruding ring 14 for inserting into the outlet 10 is provided on the inlet 13 side of the top of the water tank 4. A fastening groove 15 for engaging with the elastic buckle 16 on the main body 1 is provided at the bottom of the water tank 4. An elastic buckle mounting groove is provided at the bottom of the main body 1, and the elastic buckle 16 is hinged within the groove. A spring 17 is provided between the end of the elastic buckle 16 away from the water tank 4 and the main body 1. This structure allows for easy assembly and disassembly of the water tank 4, facilitating water emptying and cleaning.

[0022] In this embodiment, the water inlet 13 of the water tank 4 is provided with an extension pipe 18 extending into the middle or bottom of the water tank 4. This structure ensures that when the glass washing machine is rotating and swinging, or even when it is inverted, water is unlikely to flow back from the water tank 4 into the main housing 5 due to the obstruction of the extension pipe.

[0023] In this embodiment, an annular groove is provided on the outer wall of the convex ring 14, and a sealing ring 19 is fitted on the annular groove. This structure is used to increase the sealing between the water tank 4 and the outlet 10 and to prevent leakage.

[0024] The above are merely preferred embodiments of this utility model.
