[0032] To make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the embodiments of the present invention will be described clearly and completely in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them.

[0035] See attached Figure 1-10 , shown is an electric mopping and sweeping machine, comprising a machine body 1, on which a traveling mechanism connected to a control mechanism 2, a sweeping mechanism 3, a dust collecting mechanism 5, a mopping mechanism 4 and a water spraying mechanism are mounted. The machine body 1 moves under the control of the traveling mechanism, and the traveling mechanism generally includes driving wheels on both sides and a universal wheel at the front end.

[0036] The two groups of sweeping mechanisms 3 are arranged side by side at the bottom of the front end of the body 1. Each group of sweeping mechanisms 3 includes a first driving motor 301, a first gear transmission group 306 and a cleaning brush assembly 307. The output end of the first driving motor 301 is equipped with the first gear transmission group 306. The output end of the first gear transmission group 306 is detachably equipped with the cleaning brush assembly 307. The dust suction port of the dust suction mechanism 5 is arranged between the two groups of cleaning brush assemblies 307. The two groups of sweeping mechanisms 3 work synchronously under the control of their respective motors, and transmit power to the cleaning brush assembly 307 through the corresponding first gear transmission group 306. The two groups of cleaning brush assemblies 307 rotate in opposite directions, sweeping the dust toward the central dust suction port and sucking it into the dust box. The two sides and the rear side of the dust suction port can be provided with enclosures to facilitate the concentrated suction of dust. The cleaning brush assembly 307 can be disassembled for easy maintenance and replacement.

[0037] In some embodiments, the first drive motor 301 and the first gear transmission assembly 306 are installed in a main shell in the body 1, and the main shell includes an upper shell 302 and a lower shell 304 that are assembled and connected. The upper shell 302 is provided with a groove cavity 303 with an upper opening, and the first drive motor 301 is installed in the groove cavity 303. The bottom of the groove cavity 303 is provided with a connecting hole for the output end of the first drive motor 301 to pass through; the first gear transmission assembly 306 is installed in the accommodating cavity 305 formed between the upper shell 302 and the lower shell 304, and the head end of the first gear transmission assembly 306 is connected to the output end of the first drive motor 301, and the tail end of the first gear transmission assembly 306 is provided with an output shaft, and the output shaft passes through the body 1 downward to detachably install the cleaning brush assembly 307.

[0038] The main housing includes an upper housing 302 and a lower housing 304, which can be assembled by common means such as bolts. The main housing itself can also be installed in the machine body by a bolt structure. The open slot 303 is convenient for installing the first drive motor 301. When installed on the corresponding equipment body, the main housing, the first drive motor 301 and the first gear transmission assembly 306 can be installed first, and then installed in the machine body 1, and then the cleaning brush assembly 307 can be installed at the bottom of the machine body 1 corresponding to the output shaft of the first gear transmission assembly 306. The main housing can be installed and fixed with the corresponding equipment by setting mounting holes on the periphery, such as the mounting holes are fixed to the equipment by screws.

[0039] In some embodiments, the cleaning brush assembly 307 includes a base, the base is assembled with the output shaft of the corresponding first transmission gear assembly, a cavity is formed in the base, a chassis with longitudinal mobility is installed in the cavity, a compression spring is arranged between the chassis and the inner top wall of the base, a plurality of bundles of brushes are arranged around the chassis, and a plurality of through holes corresponding to the brushes are arranged around the base, and the brushes pass through the through holes. The brush is in contact with the ground, and although it has a certain degree of softness and can bend and deform to cope with obstacles, the chassis on which the brush is installed can move up and down elastically, which can enhance the mobility of the brush and enable it to better overcome obstacles, avoiding the negative impact of the brush's rapid deformation caused by its single deformation ability to cope with obstacles.

[0040] Furthermore, the inner top wall of the base is provided with a first longitudinal axis, the chassis is provided with a second longitudinal axis, the first longitudinal axis and the second longitudinal axis are sleeved so as to be longitudinally movable, and the compression spring is sleeved around the first longitudinal axis and the second longitudinal axis. The sleeved fit of the first longitudinal axis and the second longitudinal axis can enhance the stability of the chassis in up and down movement.

[0041] In some embodiments, the base is assembled with the corresponding output shaft by bolts, and corresponding screw holes are provided at the bottom end of the output shaft and the base. The bolts are screwed from the screw holes on the base into the screw holes at the bottom end of the output shaft, thereby assembling the two.

[0042] The two groups of mopping mechanisms 4 are arranged side by side at the bottom of the rear end of the body 1, and each group of mopping mechanisms 4 includes a second drive motor 401, a second gear transmission assembly 402 and a mopping assembly 403. The output end of the second drive motor 401 is installed with the second gear transmission assembly 402, and the output end of the second gear transmission assembly 402 is detachably installed with the mopping assembly 403. The motors of the two groups of sweeping mechanisms 3 generate driving force, which is transmitted to the mopping assembly 403 via the corresponding second gear transmission assembly 402. The two groups of mopping assemblies 403 rotate in opposite directions. Since the mopping assembly 403 has a large contact area with the ground and a large friction force, the two groups of mopping assemblies 403 rotate in opposite directions, which can complete the mopping action while also facilitating the balance of the body 1 during the movement.

[0043] The installation position of the nozzle 6 of the water spraying mechanism is between the two groups of mopping mechanisms 4 so as to spray water toward the middle area between the two groups of mopping mechanisms. The nozzle 6 has an axially through inner cavity channel for water to pass through. The inner cavity channel includes a first cavity section 601 and a second cavity section 602 connected in sequence. A resiliently mounted valve plug 603 is provided in the second cavity section 602. The valve plug 603 is triggered by the corresponding water pressure to control the opening and closing between the first cavity section 601 and the second cavity section 602. A spraying part is arranged at the bottom of the nozzle 6, and the spraying part is connected to the second cavity section 602 of the inner cavity channel.

[0044] The existing electric mopping and sweeping machine has defects in its nozzle 6. After the pump assembly stops working, water in the pipeline may leak out through the nozzle 6. The improved nozzle 6 is controlled by the valve plug 603. When working, the inner cavity channel is subjected to strong water pressure to open the valve plug 603. When the device is shut down, the water pressure in the inner cavity channel is weakened and the valve plug 603 is reset and closed under the action of elastic force. Therefore, the nozzle 6 itself has the function of controlling the water flow and effectively avoiding water leakage.

[0045] In some embodiments, the radial dimension of the first cavity section 601 of the spray head 6 in the water spray structure is smaller than the radial dimension of the second cavity section 602 ; the valve plug 603 is elastically supported below the outlet end of the first cavity section 601 .

[0046] In some embodiments, one end (connecting end 600) of the nozzle 6 is provided with a thread so as to be assembled and connected with the water delivery port of the water tank on the body 1. The other end of the nozzle 6 has an end cap assembly provided with the spraying part. The end cap assembly includes a cover body 606 and a bottom plate 607. The bottom plate 607 is installed in the cover body 606. For example, a sinking step is formed in the cover body 606, and the bottom plate 607 is tightly placed therein. The spraying part includes a spray hole 609 provided on the bottom plate 607 and a spray port 610 on the cover body 606. The spray hole 609 is relatively small. When a strong water flow passes through the spray hole 609, it will be strongly dispersed. The spray port 610 corresponds to the position of the spray hole 609 and has a sufficient size to reduce the obstruction of the spray hole 609, so that the water flow can be sprayed to the ground over a larger area. A base 604 is provided on the inner side of the end cap assembly, and the valve plug 603 is installed on the base 604 through a compression spring 605. The base 604 becomes the fulcrum for the elastic activity of the valve plug 603. When water flows into the inner cavity channel and the water pressure increases, the valve plug 603 is forced to move downward, and the compression spring 605 is in a compressed energy storage state. The base 604 becomes the fulcrum for the force, and the water flows out through the spray hole 609 and the spray port 610. When the equipment is shut down and the water pressure weakens, the compression spring 605 releases energy to push the valve plug 603 upward, thereby blocking the outlet end of the first cavity section 601.

[0047] In some embodiments, the bottom plate 607 has a receiving cavity connected to the second cavity section 602, the spray hole 609 is arranged in the middle of the receiving cavity, the base 604 falls in the receiving cavity, a gap channel 608 is formed between the base 604 and the side wall of the receiving cavity, and a groove 611 is provided on the bottom surface of the base 604 to connect the gap channel 608 and the spray hole 609. Preferably, the upper part of the spray hole 609 is in an inverted cone shape, and the lower part of the spray hole 609 is in a straight hole shape, and the size of the lower part is comparable to that of the top of the upper part. The upper part is convenient for sufficient water flow to enter, and the straight hole-shaped lower part is conducive to the pressurized spraying of water flow.

[0048] The above description is only the preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications, combinations and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
