Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and more particularly to a cleaning machine. Background Technology

[0002] Leather and fabric sofas and carpets have become increasingly common household items in modern homes, and their cleaning is receiving more and more attention. Cleaning methods mainly involve manual labor or foam cleaning machines. However, manual cleaning is labor-intensive and doesn't achieve high levels of cleanliness. While foam cleaning machines can replace manual labor and improve efficiency, they have drawbacks such as not being able to dry items quickly enough and being relatively heavy and cumbersome. Specialized cleaning machines can better solve the cleaning problems of these types of furniture and household items, offering advantages such as high efficiency, portability, and ease of maintenance.

[0003] Existing cleaning machines are equipped with cleaning brushes and water spraying devices to clean the surfaces of fabrics and other products. The internal fan of the cleaning machine generates suction to extract the wastewater from the surface after cleaning and collect it into the wastewater tank. However, existing cleaning machines are functionally limited, typically only having a wastewater extraction channel and lacking a blowing function. The air output by the fan is directly discharged to the outside without being effectively utilized. This makes it impossible to treat the residual moisture on the surface of the cleaned products, and the natural evaporation process of the moisture takes a long time, causing inconvenience to users.

[0025] This application provides a cleaning machine to address the technical problem that existing cleaning machines have limited functionality, typically only having a channel for absorbing wastewater and lacking a blowing function. The air output by the blower is directly discharged to the outside without being effectively utilized, making it impossible to treat the residual moisture on the surface of fabric products. The natural evaporation process of the moisture takes a long time, causing inconvenience to users.

[0026] To make the inventive objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] Please see Figures 1 to 8This application provides a cleaning machine, including a body 100 and a fan 200. The fan 200 is located inside the body 100. The body 100 has an air inlet 110 and an air outlet 120. The air inlet end of the fan 200 is connected to the air inlet 110, and the air outlet end is connected to the air outlet 120. A suction pipe is inserted into the air inlet 110. The fan 200 draws air, causing the suction pipe to draw in dirt. The air drawn by the fan 200 is discharged through the air outlet end. The machine also includes a blowing pipe. The air outlet 120 is connected to the blowing pipe, so that the blowing pipe is inserted into the air outlet 120. The air drawn by the fan 200 is concentrated and output through the blowing pipe to form a blowing state. An air outlet component 300 is installed inside the air outlet 120, forming an exhaust chamber 310. The air outlet end of the fan 200 is connected to the exhaust chamber 310. An exhaust hole 130 is also provided on the body 100 near the air outlet 120, and the exhaust hole 130 is connected to the exhaust chamber 310. A baffle 320 is pivotally connected inside the air outlet component 300, which can cover the air outlet 120. When the cleaning machine is in suction mode, the suction pipe is connected to the air inlet. Air is discharged through air inlet 110 and exhaust vent 200 through exhaust vent 130. When the cleaning machine is in blower mode, the blower pipe is connected to air outlet 120, baffle 320 rotates and closes exhaust vent 130, and the blower 200 only discharges air through air outlet 120. The suction pipe and the blower pipe are the same external pipe. When the cleaning machine is in suction mode, this external pipe is connected to air inlet 110. When the cleaning machine is in blower mode, this external pipe is connected to air outlet 120.

[0028] Specifically, the air inlet 110 and air outlet 120 are located on the side wall of the body 100 near the bottom, and on different sides of the body 100. The fan 200 is installed inside the body 100 and connects with the air inlet 110 and air outlet 120 to form an airflow channel. Both the air inlet 110 and air outlet 120 are tubular and extend outward from the side wall of the body 100. The air outlet component 300 has an internal exhaust cavity, with one side wall being an opening that abuts against the side wall of the body 100 where the air outlet 120 and exhaust hole 130 are located, thus connecting the air outlet 120, exhaust hole 130, and exhaust cavity 310. The cleaning brush 500 of the cleaning machine is connected to the air inlet 110 and air outlet 120 through a pipe to perform the function of suctioning sewage or blowing air. The baffle 320 pivotally connected inside the air outlet component 300 covers the air outlet 120. In this example, the suction pipe and the blowing pipe are the same pipe. When in suction mode, the pipe is inserted into the air inlet 110, and the air outlet 120 is not connected to the pipe. The air discharged by the fan 200 enters the exhaust chamber 310 and is discharged to the outside of the machine body 100 through the exhaust hole 130. When the pipe is inserted into the air outlet 120, the baffle 320 is pushed to one side by the pipe, covering the exhaust hole 130, so that the air discharged by the fan 200 is concentrated at the air outlet 120, ensuring that the air output by the pipe is sufficient. Since the fan 200 generates heat during operation, the output air has a certain temperature, which is conducive to accelerating the evaporation of residual moisture on the surface of the cleaning product. The baffle 320 is used to control the air outlet direction of the fan 200 to effectively utilize the air outlet of the fan, increase the function of the cleaning machine, and further improve the practicality of the cleaning machine.

[0029] Furthermore, the exhaust hole 130 is formed by several strip holes arranged in parallel, and the inner side of each strip hole extends with an arc-shaped wall 131 facing the air outlet 120; the interior of the air outlet component 300 is provided with a partition wall 330 that separates the air outlet 120 from the exhaust hole 130, and a ventilation hole 331 is provided on the partition wall 330; after the air outlet 120 is connected to the pipe, the baffle 320 rotates to cover and seal the ventilation hole 331. The strip-shaped holes and the arc-shaped wall 131 are arranged side by side, with the arc-shaped wall 131 facing the air outlet 120, which is conducive to the exhaust of air. The partition wall 330 is horizontally arranged inside the air outlet 300 to separate the air outlet 120 and the exhaust hole 130, dividing the exhaust chamber 310 into two chambers. The bottom surface of the chamber where the exhaust hole 130 is located is also provided with multiple strip-shaped holes. When the baffle 320 seals the air outlet 120, the air output by the fan 200 enters the chamber where the exhaust hole 130 is located through the ventilation hole 331. When the air outlet 120 is connected to a pipe, the baffle 320 is pushed to one side by the pipe and rotates to cover the ventilation hole 331, and the fan 200 exhausts air through the air outlet 120.

[0030] Furthermore, a connecting post 321 is provided on one side of the baffle 320, and a fixing hole 340 is provided on the inner wall of the air outlet 300 corresponding to the bottom surface of the body 100. The connecting post 321 is pivotally connected to the fixing hole 340. The middle part of the baffle 320 protrudes to one side to form a circular blockage 322. The blockage 322 is embedded in the air outlet 120, and the side of the blockage 322 near the air outlet 120 is an inclined surface 323. A fixing hole 340 is located on the inner wall of the air outlet 300 near the air outlet 120. The bottom surface of the body 100 has a hole corresponding to the fixing hole 340. The two ends of the connecting column 321 are pivotally connected to the fixing hole 340, so that the baffle 320 can rotate around the fixing hole 340. The middle part of the baffle 320 protrudes towards the air outlet 120 to form a blockage 322, which is embedded in the air outlet 120 to block the air outlet 120. The side near the air outlet 120 is inclined from bottom to top. When the pipe is inserted into the air outlet 120, the inclined surface 323 makes it easy to push the baffle 320 towards the partition wall 330 after the pipe comes into contact with the blockage 322. Thus, the position of the baffle 320 is fixed by the contact between the inclined surface 323 and the pipe. The overall structure is simple and easy to operate.

[0031] Furthermore, it also includes a connector 400 and a cleaning brush 500. One end of the suction pipe and the blowing pipe are connected to the air inlet 110 and the air outlet 120 through the connector 400, and the other end is connected to the cleaning brush 500. The outer wall of the connector 400 is provided with a slot 410, and the side walls of the air inlet 110 and the air outlet 120 are provided with buckles 140. When the connector 400 is inserted into the air inlet 110 or the air outlet 120, the buckles 140 are fastened to the slot 410. The side wall of the connector 400 includes a first region 420 and a second region 430. The outer diameter of the first region 420 is smaller than the outer diameter of the second region 430. The first region 420 is inserted into the interior of the air outlet 120 and extends into the exhaust cavity 310. The baffle 320 is rotated by the push of the first region 420. The side wall of the connector 400 extends into an elliptical snap-fit ​​groove 440, and a slot 410 is formed at the bottom of one side of the snap-fit ​​groove 440. A button 450 is pivotally connected to the snap-fit ​​groove 440. When the connector 400 is installed, the buckle 140 extends into the snap-fit ​​groove 440 through the slot 410 and snaps onto the inner wall of the button 450. When the connector 400 is disassembled, the side of the button 450 away from the slot 410 is pressed to tilt the button 450, and the buckle 140 is released from the restraint of the button 450. The cleaning machine comes with a cleaning brush 500 for cleaning and vacuuming. A flexible hose connects the cleaning brush 500 to the connector 400. The air inlet 110 and air outlet 120 are the same size and both tubular, with a trapezoidal buckle 140 located on one side of the outer wall. The side wall of the connector 400 consists of a first region 420 and a second region 430 with different outer diameters. The outer diameter of the first region 420 is smaller than the inner diameter of the air outlet 120, while the outer diameter of the second region 430 is the same as the outer diameter of the air outlet 120. When the connector 400 is installed, the first region 420 extends into either the air inlet 110 or the air outlet 120. When inserted into the air outlet 120, the first region 420 pushes the baffle 320 to one side to open the air outlet 120. The snap-fit ​​groove 440 is mainly located on the side wall of the second region 430. The groove 410 is formed at the bottom of one side of the snap-fit ​​groove 440, which is the step formed by the first region 420 and the second region 430. The back of the button 450 is a groove, and cylindrical parts extend from both sides to be inserted into the snap-fit ​​groove 440. The side wall of the button 450 relative to the slot 410 is higher than the other side wall. When the connector 400 is installed, the buckle 140 extends into the snap-fit ​​groove 440 through the slot 410 and is fastened to the inner wall of the button 450 for a secure connection. When the button 450 is pressed away from the slot 410, the button 450 tilts, and the buckle 140 is not limited by the inner wall of the button 450 and can be released from the snap-fit ​​groove 440, allowing the connector 400 to be disassembled. The connector 400 is inserted into the air inlet 110 and the air outlet 120 so that the cleaning brush 500 has the functions of suction and blowing.

[0032] Furthermore, it also includes a sewage tank 600, which has a water inlet pipe 610 extending upward from the bottom, and an air inlet 110 connected to the water inlet pipe 610; the top of the sewage tank 600 is covered with an air guide 620, and the air inlet of the blower 200 is connected to the air guide 620. The air guide 620 has an air guide port 630, and a partition plate 640 extends downward from the lower end face of the air guide 620. One side of the partition plate 640 partially surrounds the water inlet pipe 610, and the air guide port 630 is located on the other side of the partition plate 640; the upper end face of the air guide 620 is covered with an air guide cover 650 that communicates with the air guide port 630, and the other end of the air guide cover 650 is connected to the air inlet of the blower 200. The wastewater tank 600 is installed on one side of the body 100. The air inlet 110 is located below the wastewater tank 600. One end of the water inlet pipe 610 is connected to the air inlet 110, and the other end extends to the vicinity of the air guide 620. The partition plate 640 extends from the lower end of the air guide 620 to the bottom of the wastewater tank 600. It is arc-shaped and partially surrounds the top opening of the water inlet pipe 610. The air guide 630 is located on the other side of the partition plate 640 and connects the upper and lower ends of the air guide 620. One end of the air guide cover 650 is connected to the air guide 630, and the other end is connected to the air inlet of the blower 200 to form an airflow channel. The partition plate 640 is set so that when the wastewater enters the wastewater tank 600 through the water inlet pipe 610 in the suction state, it is blocked by the partition plate 640, which reduces the amount of dirt and wastewater entering the blower 200 through the air guide 630 and reduces the cleaning frequency of the blower 200.

[0033] Furthermore, a bracket 150 is fixed inside the body 100, and the fan 200 is fixed on the bracket 150. A filter 210 is installed at the upper end of the fan 200, and the top of the filter 210 is a first inlet 211. A notch is provided at the connection between the fan 200 and the filter 210 to form a first outlet 220. The bracket 150 is provided with a connecting frame 151, and the two ends of the connecting frame 151 are respectively connected to the first outlet 220 and the air outlet 300, so as to guide the air outlet of the fan 200 into the exhaust chamber 310. A second inlet 230 is provided at the bottom of the fan 200, and a second outlet 240 is provided on the side wall of the fan 200. Air enters from the lower side of the fan 200 through the second inlet 230 and is discharged through the second outlet 240 for heat dissipation. A heat dissipation hole 160 is provided at the bottom of the side wall of the body 100, and the heat dissipation hole 160 is connected to the second outlet 240. The filter 210 is installed at the top of the fan 200 to filter the air entering the fan 200, preventing dirt from adhering inside the fan 200 and affecting its normal operation. The top of the filter 210 has a first inlet 211, which is the air inlet of the fan 200. The notch at the connection between the fan 200 and the filter 210 is the first outlet 220. Multiple openings are provided on the side wall inside the fan 200 corresponding to the first outlet 220 to collect the discharged air and output it through the first outlet 220. The two ends of the connecting bracket 151 are connected to the first outlet 220 and the air outlet component 300, respectively, forming a closed air outlet channel to distribute the air output by the fan 200. The air is introduced into the exhaust chamber 310 through the connecting frame 151. In this embodiment, the fan 200 is a dual-duct fan 200. The lower part of the fan 200 is a heat dissipation duct. The second inlet 230 is located at the bottom of the fan 200. After the air enters from the bottom, it is output through the second outlet 240 on the side wall. The second outlet 240 is connected to the bracket 150. A closed channel is formed on the bracket 150 to connect the second outlet 240 and the heat dissipation hole 160.

[0034] In this embodiment, both the air inlet 110 and the air outlet 120 are located at the bottom of the body 100. The air inlet 110 is connected to the water inlet pipe 610 of the sewage tank 600. The airflow from the blower 200 flows through the air guide 630 and the inside of the air guide cover 650, and then enters the filter 210 through the first input port 211. After being filtered by the filter 210, the airflow enters the blower 200 and is output through the first output port 220. The first output port 220 forms a closed channel with the air outlet 300 through the connecting bracket 151. The cleaning brush 500 is connected to the air inlet 110 and the air outlet 120 through the connector 400. The outer wall buckles 140 of the air inlet 110 and the air outlet 120 extend into the fastening groove 440 through the slot 410 and fasten to the inner wall of the button 450 to ensure a stable connection. By pressing one side of the button 450, the buckles 140 are disengaged from the limit of the button 450. Disassemble connector 400; when in suction mode, connector 400 is connected to air inlet 110, baffle 320's blockage 322 is embedded in air outlet 120, the vent is open, and the air output by fan 200 flows through ventilation hole 331 to exhaust hole 130 and is output from exhaust hole 130; when the blowing function is required, connector 400 is inserted into air outlet 120, the first area 420 of connector 400 extends into air outlet 120, pushes baffle 320 to one side of partition plate 640, covers ventilation hole 331, and the air output by fan 200 is output through air outlet 120; because the inner diameter of connector 400 reduces the size of the airflow channel, the output wind speed is increased, and the heat generated when fan 200 is running makes the air outlet warm, which accelerates the evaporation of moisture, effectively utilizes the exhaust of fan, and improves the practicality of the product.
