DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] like Figures 1 to 7 As shown, the utility model provides a low-noise compact sweeper, comprising:

[0031] A chassis 1, a sweeper body 2 is fixedly mounted on the top of the chassis 1;

[0032] The noise reduction mechanism 3 is arranged in the middle of the bottom end of the chassis 1;

[0033] A disassembly mechanism 4, which is arranged on the left side of the bottom end of the chassis 1;

[0034] The noise reduction mechanism 3 includes a positioning block 301, which is fixedly mounted on the left side of the front end of the chassis 1, a first sound insulation board 302 is movably mounted on the left end of the positioning block 301, a rear end of the first sound insulation board 302 is movably connected to the front end of the chassis 1, a fixing block 303 is movably mounted on the left end of the first sound insulation board 302, a rear end of the fixing block 303 is fixedly connected to the front end of the chassis 1, a connecting plate 304 is movably sleeved at the bottom end of the first sound insulation board 302, a first spring 305 is fixedly mounted on the left and right sides of the top of the connecting plate 304, the other end of the first spring 305 is fixedly mounted on the top of the first sound insulation board 302, a second sound insulation board 306 is fixedly mounted on the bottom end of the connecting plate 304, the bottom end of the second sound insulation board 306 passes through the first sound insulation board 302 and extends to the outside of the first sound insulation board 302, and the first spring 305 keeps the connecting plate 304 in place.

[0035] Since the first spring 305 and the second sound insulation board 306 are fixedly installed at the upper and lower ends of the connecting plate 304, when the second sound insulation board 306 is squeezed, the second sound insulation board 306 will move upward along the inner surface of the first sound insulation board 302 with the connecting plate 304 and compress the first spring 305. Under the restoring action of the first spring 305, the connecting plate 304 and the second sound insulation board 306 will be restored to their original positions, thereby ensuring the fitting state of the second sound insulation board 306 and the ground, thereby cooperating with the first sound insulation board 302 to achieve relative isolation of the dust collection area of ​​the sweeper, thereby achieving the purpose of reducing noise.

[0036] Wherein, the disassembly mechanism 4 includes:

[0037] A push rod 401, which is movably mounted on the left end of the fixed block 303, and a round rod 402 is fixedly sleeved inside the push rod 401, and the right end of the round rod 402 passes through the fixed block 303 and extends to the inside of the left end of the first sound insulation board 302;

[0039] When the push rod 401 is pulled, the round rod 402 will move along the inner surface of the fixed block 303 with the round plate 403 and compress the second spring 404, so that the round rod 402 and the first sound insulation board 302 are separated, thereby releasing the locking of the first sound insulation board 302 by the round rod 402.

[0040] A dust collecting pipe 5 is fixedly installed in the middle of the front end of the chassis 1, and cleaning discs 6 are fixedly installed on the upper and lower sides of the right side of the front end of the chassis 1 respectively.

[0041] Due to the existence of the cleaning disc 6, the ground can be cleaned, and the existence of the dust collecting pipe 5 can absorb debris and dust.

[0042] A fixing rod 7 is fixedly installed on the left part of the front side of the bottom end of the chassis 1, and a stopper 8 is fixedly sleeved on the bottom of the outer surface of the fixing rod 7. There are two stoppers 8 with the same shape and size.

[0043] The existence of the stopper 8 will play a supporting and limiting role.

[0044] Among them, a driven gear 9 and a first mounting rod 10 are movably installed between the two blocks 8, the top end of the driven gear 9 and the front side of the bottom end of the first mounting rod 10 are fixedly connected, the inner surfaces of the driven gear 9 and the first mounting rod 10 are movably connected to the outer surface of the fixed rod 7, and the first rubber guide plate 11 is fixedly installed on the rear side of the bottom end of the first mounting rod 10.

[0045] When the driven gear 9 rotates, the first mounting rod 10 and the first rubber guide plate 11 are driven to rotate together.

[0046] Among them, a power motor 12 located on the right side of the fixed rod 7 is fixedly installed on the front side of the bottom end of the chassis 1, and a rotating shaft 13 is fixedly sleeved on the other end of the output shaft of the power motor 12. A driving gear 16 is fixedly sleeved on the bottom of the outer surface of the rotating shaft 13. The outer surface of the driving gear 16 is meshed with the outer surface of the driven gear 9, and the driving gear 16 will cause the driven gear 9 to rotate.

[0047] When the power motor 12 is started, the rotating shaft 13 drives the driving gear 16 to rotate, thereby causing the driven gear 9 meshing with the driving gear 16 to rotate.

[0048] The top of the driving gear 16 is fixedly mounted with a second mounting rod 14 , the inner surface of the second mounting rod 14 is movably sleeved with the outer surface of the rotating shaft 13 , and the rear side of the bottom of the second mounting rod 14 is fixedly mounted with a second rubber guide plate 15 .

[0049] When the driving gear 16 rotates, the second rubber guide plate 15 will rotate together with the second mounting rod 14 .

[0050] The working principle and use process of this utility model:

[0051] First, when using the sweeper, the operator starts the power motor 12, so that the rotating shaft 13 drives the driving gear 16 to rotate, so that the driven gear 9 meshing with the driving gear 16 rotates in the opposite direction. At this time, the first mounting rod 10 and the second mounting rod 14 respectively fixedly connected to the driven gear 9 and the driving gear 16 will respectively drive the first rubber guide plate 11 and the second rubber guide plate 15 to rotate together, so as to adjust the angle between the first rubber guide plate 11 and the second rubber guide plate 15, and then guide the debris to prevent the debris from being missed. With the mutual cooperation of various mechanisms, the cleaning quality and efficiency of the sweeper are improved.

[0052] During the operation of the dust collecting tube 5, due to the restoring effect of the first spring 305, when the second sound insulation board 306 moves along the inner surface of the first sound insulation board 302 with the connecting plate 304, the first spring 305 will generate a reverse force on the connecting plate 304, so that the second sound insulation board 306 always keeps in contact with the ground, and then cooperates with the first sound insulation board 302 to form a relatively isolated state around the dust collecting tube 5, thereby reducing the noise generated by the dust collecting tube 5. When the second sound insulation board 306 needs to be replaced, the operator only needs to push the push rod 401, so that the round rod 402 moves along the inner surface of the fixed block 303 with the round plate 403 and compresses the second spring 404, so that the round rod 402 and the first sound insulation board 302 are separated, and the locking of the round rod 402 on the first sound insulation board 302 is released. Then the operator can remove the first sound insulation board 302 and the second sound insulation board 306, so as to facilitate their replacement.
