[0015] The utility model is described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] Please refer to Figures 1 to 6 The dust box assembly structure of the embodiment of the utility model comprises a bottom shell 1, a magnetic frame 2, a dust box 3, an operating rod support 4, an operating rod 5, a first magnetic member and a second magnetic member.

[0017] The bottom of the bottom shell 1 is provided with a first limiting portion 11 and a second limiting portion 12. In a specific embodiment, the first limiting portion 11 and the second limiting portion 12 are stop surfaces formed by injection molding.

[0018] The magnetic bracket 2 is mounted on the bottom shell 1 so as to be movable forward and backward. In this embodiment, the magnetic bracket 2 is mounted on the bottom shell 1 so as to be movable forward and backward. The left and right sides of the bottom shell 1 are respectively provided with guide grooves 13 extending in the front-back direction; the left and right sides of the magnetic bracket 2 are respectively provided with guide blocks 23 protruding inward, and the guide blocks 23 are columnar, and the two guide blocks 23 of the magnetic bracket 2 extend into the two guide grooves 13 of the bottom shell 1 respectively.

[0019] In a specific embodiment, the magnetic frame 2 includes a magnetic frame body 2a, a first longitudinal beam 2b and a second longitudinal beam 2c, the first longitudinal beam 2b and the second longitudinal beam 2c are respectively connected to the left and right sides of the magnetic frame body 2a, and two guide blocks 23 are respectively arranged on the inner side of the first longitudinal beam 2b and the inner side of the second longitudinal beam 2c, and face each other. The bottom shell 1 includes a bottom shell body 1a and a boss 1b that rises upward from the middle of the bottom shell body, and the left and right sides of the top surface of the boss 1b are respectively provided with a first guide rail 15 and a second guide rail 16 extending along the front-back direction of the bottom shell 1, and two guide grooves 13 are respectively opened on the left and right sides of the boss 1b. The magnetic frame body 2a is pressed on the first guide rail 15 and the second guide rail 16, and the first guide rail 15 and the second guide rail 16 are located between the first longitudinal beam 2b and the second longitudinal beam 2c.

[0020] The joystick support 4 is connected to the bottom shell 1, and the joystick 5 is rotatably arranged on the joystick support 4. By rotating the joystick 5, the magnetic suction bracket 2 can be driven to move between the adsorption position and the release position. In this embodiment, the joystick support includes a first support 41 and a second support 42, and the two ends of the joystick 5 are rotatably supported on the first support 41 and the second support 42 respectively. A protruding shift block 50 is provided on the side of the joystick 5, and a groove 20 matching the shift block is provided on the end surface of the magnetic suction bracket 2, and the shift block 50 extends into the groove 20. The two opposite sides of the groove 20 are provided with a stop protrusion 22 extending into the groove at the mouth of the groove, and the stop protrusion 22 is used to prevent the shift block 50 from escaping from the mouth of the groove 20.

[0021] Preferably, the joystick 5 comprises a shaft 5a and a button 5b, wherein the button 5b is connected to one end of the shaft 5a. The shift block 50 is connected to the side of the shaft 5a.

[0022] The first magnetic member is mounted on the magnetic frame 2, and the second magnetic member is mounted on the dust box 3. In this embodiment, the first magnetic member includes a plurality of first magnets 61, and the plurality of first magnets 61 are respectively mounted on the bottom surface of the magnetic frame 2; the second magnetic member includes the same number of second magnets 62 as the plurality of first magnets 61, and the plurality of second magnets 62 are respectively mounted on the top of the dust box 3.

[0023] In a specific embodiment, the number of the first magnet 61 and the second magnet 62 are both four, of which two first magnets 61 are respectively arranged at the front end and the rear end of the bottom surface of the first longitudinal beam portion 2b, and the remaining two first magnets 61 are respectively arranged at the front end and the rear end of the bottom surface of the second longitudinal beam portion 2c, and the four second magnets 62 are respectively arranged at the four corners of the dust box 3. The bottom surface of the first magnet 61 is opposite to the magnetic properties of the top surface of the corresponding second magnet 62, so that the two can attract each other. For example, if the bottom surface of the first magnet 61 is the N pole, the magnetic pole of the top surface of the corresponding second magnet 62 is the S pole.

[0024] Please refer to Figure 5 When the button 5b is in the closed state and the magnetic frame 2 is in the adsorption position, the plurality of first magnets 61 are aligned with the plurality of second magnets 62 one by one, and the plurality of first magnets 61 are attracted to the plurality of second magnets 62 one by one through the bottom shell 1, so that the dust box 3 is close to the bottom of the bottom shell 1 so that cleaning can be performed. At this time, the dust box 3 is located between the first limiting portion 11 and the second limiting portion 12, and the first limiting portion 11 and the second limiting portion 12 can limit the dust box 3 from moving forward and backward respectively. In other embodiments, the first magnetic member can also directly adsorb the second magnetic member without the bottom shell.

[0025] Press the button 5b with your foot to drive the rod 5a and the shift block 50 to rotate synchronously, and the shift block 50 pushes the magnetic suction frame 2 from the suction position to the release position. Since the dust box 3 is restricted by the limit part, it cannot move with the magnetic suction frame 2. Please refer to Figure 6 When the button 5b is in the open state and the magnetic bracket 2 is in the released position, the first magnets 61 and the second magnets 62 are offset by a distance and no longer attract each other (i.e., the first magnetic members and the second magnetic members are separated from each other). Due to the effect of gravity, the dust box 3 falls off and leaves the bottom shell 1. At this time, the garbage in the dust box can be poured out and cleaned. After cleaning, the button 5b is restored to the closed state, and the dust box 3 is reset.

[0026] In a specific application, the dust box assembly structure of this embodiment is suitable for a cleaning device, such as an outdoor electric sweeper as a garden tool. The cleaning device includes a pair of roller brushes (not shown in the figure), which are rotatably mounted on the bottom shell 1 and are respectively located in front of and behind the dust box 3. When working, the roller brushes rotate under the drive of the motor to sweep dust into the dust box 3.

[0027] The embodiment of the utility model uses a magnetic suction frame installed on the bottom shell that can move forward and backward to attract the dust box. The dust box can be detached or attracted only by moving the magnetic suction frame through a joystick, and the assembly and disassembly is very convenient. Since there is no buckle, the dust box is also easier to clean.

[0028] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
