[0031] The present invention will now be described in detail with reference to the accompanying drawings.

[0032] Reference Figure 1 , Figure 4 and Figure 5 An outdoor cleaning machine with a quick-change brush head includes:

[0033] Main handle 1, for the user to hold;

[0034] Rod 2, the upper end of which is connected to the main handle 1;

[0035] Body 3 is connected to the lower end of rod 2;

[0036] Assembly 4 consists of brush heads with different functions, which can be detachably connected to the main body 3;

[0037] The disassembly and assembly structure 5 includes a lever 51 disposed on the surface of the body 3, a locking body 52 disposed inside the body 3, the locking body 52 being fixedly connected to the lever 51, the locking body 52 having a through groove for the head of the assembly 4 to be inserted, and the locking body 52 having a plurality of locking slots 521 circumferentially disposed along the inner wall of the through groove, and a plurality of locking blocks 41 being fixedly disposed on the head of the assembly 4, the lever 51 being able to drive the locking body 52 to deflect relative to the body 3, so that the locking slots 521 and the locking blocks 41 are in a positional relationship of being aligned and penetrating or misaligned and blocking, an elastic element 53 being disposed between the lever 51 and the body 3, the elastic element 53 being a spring, and a baffle 54 being fixedly disposed inside the body 3 to abut against the head of the assembly 4.

[0038] Reference Figure 5 and Figure 6 The card body 52 is integrally formed by a circular card plate 52a and a card rod 52b. The card rod 52b passes through the machine body 3 and is fixedly connected to the lever block 51. The machine body 3 has an active groove 31 for the card rod 52b to move, and the two ends of the active groove 31 can form a self-limiting position for the deflection angle of the card rod 52b.

[0039] Working principle: When in use, this cleaning machine can connect brush heads with different functions to the machine body 3 using the disassembly and assembly structure 5, as shown in the reference. Figure 7 The assembled cleaning machine shown can be used for cleaning floor tiles and removing moss, as shown in the reference. Figure 8 The assembled cleaning machine shown can be used for cleaning tile grout. During assembly, the user only needs to overcome the resistance of the elastic element 53 and move the lever 51 to the bottom, causing the locking body 52 to deflect at a certain angle, so that the locking block 41 on the assembly 4 is aligned with the locking groove 521 on the locking body 52 (in this embodiment, the number of locking blocks 41 and locking grooves 521 is set to 4, and the reasonable distribution of the number makes it easy to identify the insertion angle according to the structure of the assembly 4 when assembling it). Insert the head of the assembly 4 into the machine body 3 until the locking block 41 passes the locking groove 521 and the head of the assembly 4 abuts against the baffle 54 and cannot be inserted further. Then, release the lever 51. The lever 51 and the locking body 52 will rotate back to the initial state under the elastic recovery of the elastic element 53. At this time, the locking block 41 and the locking groove 521 are in a misaligned state, and the locking body 52 forms a limit, preventing the assembly 4 from falling out on its own. Thus, the assembly 4 and the machine body 3 are firmly connected.

[0040] This application, by setting up an assembly 4 that can be detachably installed on the body 3 and a specific disassembly and assembly structure 5, allows users to quickly replace the brush head by simply turning the lever 51 and inserting or removing the assembly 4. This enables users to quickly change to the appropriate brush head according to different cleaning scenarios, such as cleaning floor tiles, cleaning floor tile gaps, and removing moss, thereby reducing the cost of use, reducing the storage space requirement, and facilitating daily management and carrying.

[0041] Additionally, refer to Figure 5 The surface of the body 3 is integrally formed with a groove for sliding the lever 51. There are two baffles 55 fixed inside the body 3. The locking body 52 is located between the two baffles 55 and fits against them. When the user moves the lever 51, the groove and the baffles 55 effectively constrain the movement of the lever 51 and the locking body 52 respectively, ensuring the stability and reliability of the disassembly and assembly structure 5 during operation.

[0042] Reference Figure 4 Both sides of the card block 41 are chamfered. During the insertion process, the card block 41 and the card slot 521 may undergo a slight relative deflection. Therefore, the chamfer helps the card block 41 to pass through the card slot 521 more smoothly when it comes into contact with the card slot 521, reducing the difficulty of operation.

[0043] Reference Figure 2The rod body 2 is equipped with a secondary handle 6, which includes a mounting block 61 fixedly mounted on the rod body 2 and a handle 62 rotatably connected to the mounting block 61. A first blocking block 63 is fixedly mounted on the handle 62, and a second blocking block 64 is fixedly mounted on the mounting block 61 along the rotation path of the first blocking block 63, which abuts against it. When the user pulls the handle 62 upward, the first blocking block 63 rotates accordingly. When it rotates to a certain angle, the first blocking block 63 abuts against the second blocking block 64, restricting the handle 62 from continuing to rotate upward, thereby limiting the secondary handle 6 to the required angle position for use. The secondary handle 6 provides the user with a second support point, so the user's other hand can apply force to the secondary handle 6 to push the cleaner forward more smoothly. When not in use, it can be folded down for storage to save space.

[0044] Reference Figure 3 The upper surface of the main handle 1 is bonded with a flexible part 7 that conforms to the shape of the hand. The flexible part 7 is made of rubber, which has good anti-slip properties and softness. When the user holds the main handle 1 to operate the cleaning machine, the hand is in full contact with the flexible part 7, which improves the user's comfort in holding the main handle 1.

[0045] Reference Figure 4 A power drive mechanism 8 is fixedly installed inside the machine body 3. The power drive mechanism 8 includes a motor 81 and a gearbox 82. The output shaft of the motor 81 is connected to the input end of the gearbox 82, and the output end of the gearbox 82 is connected to the input end of the assembly 4. When the cleaning machine is started, the motor 81 starts to run, and its output shaft transmits power to the gearbox 82. The gearbox 82 transmits power to the assembly 4 through its internal gear transmission system, driving the brush head on the assembly 4 to rotate for cleaning. The input end of the assembly 4 and the output end of the gearbox 82 are connected by a key so that it can rotate after being inserted and assembled. Figure 7 When the brush head is being used, a synchronous pulley and synchronous belt drive structure are also provided inside the brush head to realize power transmission.

[0046] Reference Figure 3 It also includes a start switch 9 and a lock switch 10 installed on the main handle 1. The bottom of the main handle 1 is fixedly provided with a battery compartment 11 for placing the battery. When the user needs to use the cleaning machine, first install the battery into the battery compartment 11 to provide power support for the cleaning machine, and then press the start switch 9 to send a signal to the motor 81, and the cleaning machine starts to work. When it is necessary to stop working, press the lock switch 10 to prevent accidental start.

[0047] The motor 81, battery compartment 11, start switch 9, and locking switch 10 of this utility model are all electrically connected to the controller inside the machine body 3 to achieve coordinated operation. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0048] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
