Description

Technical Field

[0001] The present invention relates to the technical field of vacuum cleaner charging base stations, and in particular to a vacuum cleaner charging base station. Background Art

[0002] The vacuum cleaner charging base station is an important component of the vacuum cleaner. It not only provides charging services for the vacuum cleaner, but may also have many other functions. When the vacuum cleaner completes the cleaning task, it can be returned to the base station. The base station will automatically collect the dust and garbage inside the vacuum cleaner into the dust bag, avoiding the trouble of users manually cleaning the vacuum cleaner.

[0003] Prior art 1 (publication number: CN105708385B, Chinese patent published on 2019-06-18) is used for the base station of the vacuum cleaner, and through the correspondingly controlled valves and suction valves, a closed fluid cycle is formed between the fan of the first vacuum cleaner, the air outlet of the first vacuum cleaner, the second air outlet of the base station, the air channel of the second vacuum cleaner, the second air inlet of the base station, the dust collection chamber of the base station, and finally the fan of the first vacuum cleaner again. As a result, the fan of the first vacuum cleaner and the dust collection chamber of the second vacuum cleaner work together, so that the dust contained in the dust collection chamber of the second vacuum cleaner is transported to the base station dust collection chamber of the base station by means of the fan of the first vacuum cleaner, and the dust collected there (the dust collection chamber of the base station) can be finally removed. The base station itself does not need its own fan, because whether cleaning the dust collection chamber of the first vacuum cleaner or cleaning the dust collection chamber of the second vacuum cleaner, only the fan of the first vacuum cleaner can be used.

[0004] There is also prior art 2 (publication number: CN115426929B, Chinese patent published on 2014-02-13). The vacuum cleaner base station may include a first base station for combining with a handheld vacuum cleaner and a second base station for combining with a sweeping robot. The first base station may include a first suction part for sucking dust from the dust bucket of the handheld vacuum cleaner, and the second base station may include a second suction part for sucking dust from the dust bucket of the sweeping robot. The vacuum cleaner base station may include a dust inlet part for spitting out the dust sucked from the first suction part and the second suction part, and may also include a dust storage box that is connected to the dust inlet part and accommodates the dust sucked from the first suction part and the second suction part.

[0005] Although the existing technologies 1 and 2 can perform autonomous cleaning of the vacuum cleaner, they mostly clean dust and are unable to trim and clean the hair entangled on the outside of the roller brush of the vacuum cleaner. The hair entangled on the roller brush will affect the subsequent vacuuming effect and reduce the efficiency of the vacuuming operation.

[0006] Therefore, we propose a vacuum cleaner charging base station to solve the above problems. Summary of the invention

[0010] Preferably, the hair cutting assembly includes a movable frame, a linkage wheel body is nested and connected inside the movable frame, a linkage wheel spring is fixedly connected between the inner end of the linkage wheel body and the inside of the movable frame, and a lower blade body is fixedly and rotatably connected to the side of the movable frame, and a lower blade spring is fixedly connected between the side of the lower blade body and the inside of the movable frame, the lower blade body forms a rotating structure with the movable frame through the interference effect of the receiving protrusion, and the lower blade body forms an elastic structure with the movable frame through the lower blade spring.

[0011] Preferably, the outer side of the linkage wheel body is slidably connected to the upper blade body, and the side of the upper blade body is rotatably connected to the movable frame, and the side structure of the upper blade body adjacent to the cutting edge is designed as a concave structure.

[0012] Preferably, the outer side of the linkage wheel body is slidably connected to the upper blade body, and the side of the upper blade body is rotatably connected to the movable frame, and the side structure of the upper blade body adjacent to the cutting edge is a non-concave structure design, and the bottom end of the inclined surface of the upper blade body is inclined toward the blade direction of the lower blade body, which is used to guide the hair into between the two blades.

[0013] Preferably, the outer end of the linkage wheel body and the inner side of the interference ribs are in mutual interference, and the interference ribs are arranged in a zigzag structure, and the linkage wheel body forms a sliding structure with the inside of the movable frame through the interference ribs, and the upper blade body forms a rotating structure between the linkage wheel body and the movable frame.

[0014] Preferably, the hair supporting assembly includes an end connecting head, which is installed at the left and right ends of the roller brush center column, and the roller brush center column can be connected to the inner side of the vacuum cleaner floor brush through the end connecting head, the outer side of the roller brush center column is spirally fixed with spiral ribs, and a plurality of groups of spiral ribs are designed with a surrounding enclosure structure, and a mounting groove is formed around the interior of the plurality of groups of spiral ribs, and the interior of the mounting groove is fixedly connected with cleaning hair, a first bracket is fixed on the left side of the roller brush center column, and a second bracket is fixed on the right side of the roller brush center column, and the protruding positions of the second bracket and the first bracket and the end positions of the spiral ribs are staggered.

[0015] Preferably, the side surface of the hair support component is arranged in an arc-shaped structure, the spiral ribs are distributed in a spiral protrusion-shaped structure design along the outer surface of the central column of the roller brush, the ends of the spiral ribs are designed in an enclosed inclined structure, and the spiral ribs are evenly arranged at equal angles on the surface of the central column of the roller brush.

[0016] Preferably, a shearing groove is opened on the front side of the base station body, a soft rubber shielding strip is fixedly connected to the inner side of the shearing groove, and the other end of the soft rubber shielding strip is placed on the upper cover of the base station body, and the soft rubber shielding strip is located at the outer end side of the upper blade body and the lower blade body.

[0017] Compared with the prior art, the present invention has the following beneficial effects: A motor is arranged inside the base station body. When the motor is running, the threaded rod can be driven to rotate synchronously through the belt transmission structure. At this time, the movable frame moves laterally due to the threaded connection transmission with the threaded rod. During the movement of the movable frame, the linkage wheel body can be moved along the interference rib position. The interference between the linkage wheel body and the interference rib position can drive the shearing movement between the upper blade body and the lower blade body, thereby realizing hair trimming.

[0018] When the flat part of the conflicting rib contacts the linkage wheel body, the linkage wheel body will drive the upper blade body to rotate and perform shearing operations with the lower blade body. When the raised part of the conflicting rib does not contact the linkage wheel body, the linkage wheel body can drive the upper blade body to rotate and reset under the elastic force of the linkage wheel spring. The contact between the linkage wheel body and the conflicting rib drives the position of the upper blade body to change, and the shearing operation can be repeated.

[0019] When the edge structure adjacent to the cutting edge of the upper blade body is designed as a non-concave structure, the hair slides along the inclined surface of the upper blade body to the cutter head of the lower blade body that is longer than the upper blade body. When the upper blade body and the lower blade body are in an open state, the hair can move along the inclined surface of the lower blade body, which is convenient for cutting when the upper blade body and the lower blade body are in a closed state.

[0020] The hair supporting structure can support the hair wrapped around the central column of the roller brush, so that the hair does not directly contact the wall of the central column of the roller brush, thereby facilitating the cutting operation of the hair cutting component. The surrounding spiral ribs can further protect the cleaned hair and avoid the possibility of damage to the cleaned hair during the shearing operation. At the same time, the spiral ribs can also limit and guide the hair cutting component. When the hair cutting component conflicts with the spiral ribs, the central column of the roller brush can be driven to rotate, so that the hair cutting component can better cut the hair and improve the hair cutting effect.

[0021] The soft rubber shielding strip can shield the shearing groove provided on the base station body. When the hair cutting component is not working, the shearing groove can be shielded, which improves the aesthetics of the base station body and prevents foreign matter from falling from the shearing groove into the interior of the base station body. When the hair cutting component is working, the soft rubber shielding strip at the corresponding position of the hair cutting component can be partially pushed outward, and the hair cutting component can operate normally at this time. At the same time, the soft rubber shielding strip can also prevent hair from falling into the interior of the base station body during cutting. BRIEF DESCRIPTION OF THE DRAWINGS
