[0040] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0041] like Figures 1 to 5 As shown, this embodiment provides a cleaning machine to solve the problem that the driver 500 affects the structure of the wastewater collection tank 110, resulting in difficulty in cleaning. The cleaning machine includes a housing 100, a spray arm 400, a moving part 200, a transmission mechanism 300 and a driver 500. The shell 100 has a cleaning chamber; the spray arm 400 is located in the cleaning chamber and is provided with a spray hole 440, and the spray arm 400 extends along a first direction X of the cleaning chamber; the moving member 200 extends along a second direction Y that is angled with the first direction X, and is arranged to be able to move along its own extension direction, the spray arm 400 is assembled on the moving member 200, and can synchronously reciprocate with the moving member 200 relative to the cleaning chamber in the second direction Y; the power input end of the transmission mechanism 300 has a first transmission member 310, and the power output end of the transmission mechanism 300 has a second transmission member 320, the first transmission member 310 and the second transmission member 320 are both arranged to be able to rotate around their own axes, and the second transmission member 320 is transmission-connected to the moving member 200; the output end of the driver 500 is drivingly connected to the first transmission member 310.

[0042] The driver 500 in the cleaning machine transmits power to the moving member 200 through the transmission mechanism 300. The first transmission member 310 and the second transmission member 320 in the transmission mechanism 300 are not coaxial and can rotate around their respective axes. The second transmission member 320 is connected to the moving member 200, and the driver 500 is connected to the first transmission member 310, so that even if the second transmission member 320 is located in the middle area of ​​the cleaning chamber, due to the existence of the first transmission member 310, the installation position of the driver 500 can have more options, and can avoid the wastewater collection tank 110 at the bottom of the cleaning chamber, ensuring that the structure of the wastewater collection tank 110 is relatively simple, easy to clean, and improve user experience; at the same time, since the driver 500 and the wastewater collection tank 110 will not interfere with each other, it is beneficial to improve assembly efficiency; finally, avoiding the superposition of the wastewater collection tank 110 and the driver 500 in the height direction is beneficial to reducing the height size of the cleaning machine. Among them, the height direction is the third direction Z, and the first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0043] The first transmission member 310 and the second transmission member 320 both include transmission wheels, and the transmission mechanism 300 further includes a transmission belt 330, which is wound around the two transmission wheels in sequence. The cooperation between the transmission wheel and the transmission belt 330 can realize power transmission, and has a simple structure and low cost.

[0044] For ease of description, the transmission wheel of the first transmission member 310 is defined as a first transmission wheel 311 ; the transmission wheel of the second transmission member 320 is defined as a second transmission wheel 321 .

[0045] To ensure accurate control of the position of the moving member 200, both transmission wheels are gears, and the inner side of the transmission belt 330 has teeth that are adapted to the two gears. Exemplarily, the transmission wheel is a synchronous wheel, and the transmission belt 330 is a synchronous belt. The cooperation of the synchronous belt and the synchronous wheel can accurately complete the transmission of the output terminal rotation number of the driver 500, so that the rotation number of the second transmission member 320 can be accurately controlled according to the rotation number of the output terminal of the driver 500, and then the moving position of the moving member 200 can be accurately controlled. Wherein, the driver 500 is a servo motor.

[0046] The wastewater collection tank 110 is located in the middle area of ​​the housing 100, the second transmission member 320 is located in the middle area of ​​the cleaning chamber, and the moving member 200 reciprocates along the second direction Y. To avoid interference between the moving member 200 and the transmission belt 330 during the movement, the arrangement direction of the transmission belt 330 extends along the second direction Y, that is, the first transmission member 310 and the second transmission member 320 are arranged at intervals in the second direction Y. On this basis, the driver 500 is arranged below the first transmission member 310 and can be arranged at intervals in the second direction Y with the wastewater collection tank 110.

[0047] The second transmission member 320 further includes a linkage wheel 322, which is disc-shaped and has a peripheral wall in contact with the outer wall of the moving member 200. The linkage wheel 322 is coaxial with the second transmission wheel 321 and can rotate in a positive or reverse direction with the second transmission wheel 321, so that the moving member 200 can reciprocate relative to the cleaning chamber in the second direction Y. The linkage wheel 322 is in direct contact with the moving member 200, and converts its own circumferential motion into a linear motion of the moving member 200, thereby reducing the intermediate transmission structure and improving the energy transmission efficiency.

[0048] Combination Figure 4 As shown, the linkage wheel 322 is a gear, and the mobile member 200 is a rack, and the gear meshes with the toothed portion of the rack. The meshing transmission of the gear and the rack can effectively ensure the transmission accuracy, thereby accurately controlling the position of the rack. In another exemplary embodiment, the linkage wheel 322 is a roller, and the peripheral wall of the roller and the mobile member 200 directly roll together. In order to improve the reliability of the transmission, the peripheral sleeve of the roller is provided with a rubber sleeve to increase the friction between the roller and the mobile member 200, thereby realizing the effective transmission of power.

[0049] The top of the rack has a connection seat 210, and the spray arm 400 can be rotatably constrained on the connection seat 210. In order to prevent the residues generated during the cleaning process from falling on the teeth of the rack and being sandwiched between the rack and the gear when the rack and the gear are meshed, the teeth of the rack are arranged on the side wall adjacent to the connection seat 210, and the gear is correspondingly located beside the moving path of the rack. Even if the cleaning residues fall on the teeth, they will slide down and will not remain on the teeth, so that when the gear and the rack are meshed, the cleanliness of the meshing part is guaranteed, which is beneficial to the stability of the rack transmission.

[0050] Combination Figure 5 As shown, a flow channel is provided inside the rack, a connecting seat 210 is provided with a guide channel 212 connected to the flow channel, a bottom wall of the spray arm 400 is provided with a joint 410 extending downward, the spray arm 400 has a water containing chamber 430 and a spray hole 440 connected to the water containing chamber 430, the joint 410 is provided with a water flow inlet 411 connected to the water containing chamber 430, the joint 410 is plugged into the guide channel 212, and along the fluid flow direction, the flow channel, the guide channel 212, the water flow inlet 411, the water containing chamber 430 and the spray hole 440 are connected in sequence.

[0051] An annular limiting protrusion 211 is convexly provided on the outer periphery of the connection seat 210, and a plurality of elastic arms 420 extending downward are provided on the bottom wall of the spray arm 400. The plurality of elastic arms 420 have a tendency to gather inwards, and the plurality of elastic arms 420 are arranged on the outer periphery of the connection seat 210. The lower ends of the elastic arms 420 are located below the limiting protrusion 211 and are in sliding contact with the connection seat 210. The elastic arms 420 are elastic, so that the unbalanced force generated during the rotation of the spray arm 400 is offset by the elastic force of the elastic arms 420, thereby facilitating the rotation stability of the spray arm 400.

[0052] In order to prevent the cleaning residue from falling into the gap between the second transmission wheel 321 and the transmission belt 330, the second transmission member 320 also includes a shielding portion, which is located above the second transmission wheel 321 and has a diameter greater than the diameter of the second transmission wheel 321, so that the cleaning residue is blocked by the shielding portion after falling and will not enter the gap between the second transmission wheel 321 and the transmission belt 330, thereby ensuring the transmission accuracy between the two.

[0053] The gear of the second transmission member 320 includes a tooth body 3221 and transmission teeth 3222 arranged on the outer periphery of the tooth body 3221. The tooth body 3221 forms a shielding portion. The outer diameter of the tooth body 3221 of the gear is larger than the outer diameter of the second transmission wheel 321 to provide shielding for the second transmission wheel 321 and prevent cleaning residues from falling between the second transmission member 320 and the transmission belt 330.

[0054] Combination Figure 4As shown, similarly, the first transmission member 310 also includes a baffle plate 312 arranged above the first transmission wheel 311. The outer diameter of the baffle plate 312 is larger than the outer diameter of the first transmission wheel 311. The baffle plate 312 can shield the cleaning residues for the first transmission wheel 311 to prevent it from entering between the first transmission wheel 311 and the transmission belt 330.

[0055] In order to improve the stability of the movement of the moving member 200, the cleaning machine further includes a guide member 600, which is arranged on the housing 100 and extends along the second direction Y. The guide member 600 has a sliding groove extending along its own length direction, and the moving member 200 can be movably constrained in the sliding groove to extend out of the sliding groove or hide in the sliding groove. The guide member 600 provides a guiding sliding groove for the moving member 200, so that the movement of the moving member 200 is constrained, which is conducive to the stable movement of the moving member 200 along the second direction Y; at the same time, when the object is cleaned or before the cleaning begins, the moving member 200 can be hidden in the sliding groove to be protected by the guide member 600, so as to avoid the user from touching the moving member 200 when taking and placing the object, thereby ensuring the assembly accuracy between the moving member 200 and the guide member 600, and reducing the probability of noise or jamming due to the poor assembly accuracy between the moving member 200 and the guide member 600.

[0056] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here.
