Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to cleaning equipment. Background Technology

[0002] Mite removers are mainly used to clean dust and mites from household products, providing users with a more suitable cleaning environment. Common mite removers require moving the device around the bed during use. Because the beating area of ​​the device is limited, the user needs to walk around the bed to operate it, which is inconvenient.

[0003] The related technology discloses a mite removal device, including a handheld mechanism that is rotatably connected to the housing. The handheld mechanism includes a handle and a connecting rod. One end of the connecting rod is connected to the handle, and the other end of the connecting rod is rotatably connected to the housing. The connecting rod is a telescopic structure.

[0004] The aforementioned technologies allow users to clean beds at different angles without bending over or changing positions, making operation effortless. However, the connecting rod is attached to the rear of the housing, and when the connecting rod extends, pressing down on the handle can easily cause the front of the housing to lift up. Furthermore, the maximum length of the connecting rod is fixed, making it inconvenient to attach extension rods or replace them with connecting rods of other lengths, thus limiting the applicability of the mite remover.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0060] Mite removers are mainly used to clean dust and mites from household products, providing users with a more suitable cleaning environment. Common mite removers require moving the device around the bed during use. Because the beating area of ​​the device is limited, the user needs to walk around the bed to operate it, which is inconvenient.

[0061] The related technology discloses a mite removal device, including a handheld mechanism that is rotatably connected to the housing. The handheld mechanism includes a handle and a connecting rod. One end of the connecting rod is connected to the handle, and the other end of the connecting rod is rotatably connected to the housing. The connecting rod is a telescopic structure.

[0062] The aforementioned technologies allow users to clean beds at different angles without bending over or changing positions, making operation effortless. However, the connecting rod is attached to the rear of the housing, and when the connecting rod extends, pressing down on the handle can easily cause the front of the housing to lift up. Furthermore, the maximum length of the connecting rod is fixed, making it inconvenient to attach extension rods or replace them with connecting rods of other lengths, thus limiting the applicability of the mite remover.

[0081] In one specific embodiment, in the second position, the angle between the axis of the connecting rod 4 and the surface 6 to be cleaned is 37°.

[0082] It should be noted that when cleaning equipment cleans the bed, the bed surface is the cleaning surface.

[0083] In one embodiment, the mounting sleeve 301 is provided with a first locking part, and the adapter assembly and / or connecting rod 4 includes a second locking part, which is adapted to cooperate with the first locking part to lock the adapter body 2 and / or connecting rod 4 to the mounting sleeve 301; the handle assembly 3 also includes an unlocking structure, which is movably disposed on the body structure and is adapted to drive the second locking part to separate from the first locking part when the unlocking structure is driven.

[0084] In this embodiment, by providing a first locking part on the mounting sleeve 301 and a second locking part on the adapter body 2 and / or the connecting rod 4, when the handle assembly 3 is connected to the host 1, the second locking part on the adapter body 2 cooperates with the first locking part on the mounting sleeve 301 to lock the adapter body 2 onto the mounting sleeve 301, thus stabilizing the connection between the handle assembly 3 and the host 1 and preventing the handle assembly 3 from separating from the host 1. When it is necessary to install the connecting rod 4, the unlocking structure is activated to separate the second locking part from the first locking part. At this time, the handle assembly 3 can be separated from the host 1, and the first end of the connecting rod 4 can be inserted into the mounting sleeve 301. The second locking part of the connecting rod 4 cooperates with the first locking part of the mounting sleeve 301 to fix the first end of the connecting rod 4 into the mounting sleeve 301, and the second end of the connecting rod 4 is fixed to the adapter body 2, allowing for cleaning of a large area of ​​the surface.

[0113] In this embodiment, when the second locking button 303 is pressed, the second locking button 303 moves. Since the sliding direction of the pressure rod in the sliding groove is inclined to intersect with the moving direction of the second locking button 303, the pressure rod can be driven to move in the sliding groove, thereby driving the second locking part to leave the first locking part. The unlocking structure as a whole can achieve unlocking in a small space, with high space utilization.

[0114] Specifically, when the second locking button 303 is placed vertically, the cross-section of the sliding groove is inclined, so that when the second locking button 303 is pressed, the pressure rod moves horizontally relative to the second locking button 303.

[0115] In one embodiment not shown in the figure, the driving part may be a slider, which engages with the second locking button 303 via an inclined surface, the extension direction of which intersects the movement direction of the second locking button 303 at an angle.

[0116] In one embodiment, the main unit 1 includes a motor assembly, a display assembly 104, and a dust cup 105. When the handle assembly 3 is connected to the main unit 1, the handle assembly 3 is located diagonally above the motor assembly and behind the display assembly 104 and the dust cup 105.

[0117] In this embodiment, the handle assembly 3 is located diagonally above the motor assembly and behind the display assembly 104 and the dust cup 105, making it easier for the user to hold the handle assembly 3. This arrangement also places the handle assembly 3 at or near the center of gravity of the entire cleaning device, making it easier for the user to lift the entire device with the handle assembly 3. During operation, it is easier to control the main unit 1 by operating the handle assembly 3.
