[0052] Different from the structure in the center of the mop head 110 in the prior art, such as image 3 and Figure 4 As shown, the joint 300 in the technology of the present invention fully considers the weight of the nozzle 160 disposed in front of the mop head 110 , and the joint 300 is arranged forward along the direction of the nozzle 160 .

[0053] like figure 2 As shown, the left flange 331 and the right flange 332 of the flange 330 are fixedly connected to the lower quadrangular flange support plate 337 . The flange 330 is arranged on the upper central position of the mop head 110, and is located on the joint connection device 125 between the left and right shielding devices 122, 123.

The two straight lines of the linear guide device 333 extend from the rear end of the left and right flanges 331, 332 to the front end, and move from the rear end of the left and right flanges 331, 332 to the front end. down slope. Therefore, the two straight lines of the linear guide device 333 can be used as guide rails for the cantilever 310 that can move the nozzle nozzle 160 to move back and forth. Between the two straight lines of the linear guide device 333, the left and right pins 370, 371 that can be inserted to connect and support the cantilever 310, the flange 330 and the bracket 350 are provided. The through hole 334 is a small circle. The through hole 334 is formed obliquely from the center of the flange 330 along the front end direction.

[0055] like Figure 2~Figure 4 As shown, the cantilever 310 is connected to the rear end of the spray nozzle 160 and protrudes backward. The cantilever 310 comprises the following structures: the left and right cantilevers 311, 312; the boom 318 connected to the front ends of the left and right cantilevers 311, 312; the central position of the boom 318 for inserting The circular hose opening 319 of the suction hose.

[0056] like Figure 2~Figure 4 As shown, the left and right cantilevers 311, 312 protrude backward. The left and right cantilevers 311, 312 include the following structures: long holes 313 arranged along the front and rear length directions; pressurizing the left and right pins 370, 371 to determine the front and rear positions of the left and right cantilevers 311, 312 The position-determining convex hull 314 and the rear position-determining convex hull 315; the elongated hole 316 arranged around the elongated hole 313, the outer periphery of the elongated hole is in a gradually changing curve shape.

[0057] Various structural elements included in the left and right suspension arms 311, 312 will be described in detail below.

[0058] like Figure 2~Figure 4 As shown, the long hole 313 is located inside the left and right cantilevers 311 , 312 protruding rearward from the arm frame 318 , and is in the shape of an oblong ellipse. At the front end and the rear end of the elongated hole 313 , two front position determination protrusions 314 and rear position determination protrusions 315 are respectively provided at upper and lower positions.

[0059] like Figure 2~Figure 4 As shown, the front position-determining convex hull 314 and the rear position-determining convex hull (315) are respectively arranged at the front end and the rear end of the inner surface of the elongated hole 313, and are in the shape of small hemispherical convex hulls. The front position determining protrusion 314 exerts pressure on the left and right pins 370, 371 inserted into the elongated hole 313 from the front end position of the elongated hole 313, so that the left and right cantilever arms 311, 312 have a Backward trend. The rear position determining protrusion 315 presses the left and right pins 370, 371 inserted into the elongated hole 313 from the rear end inside the elongated hole 313, so that the left and right cantilevers 311, 312 There is a forward trend.

[0060] like Figure 2~Figure 4 As shown, the elongated holes 316 are located on the upper side and the lower side of the elongated hole 313 respectively, and are in a curved shape. When the left and right cantilevers 311, 312 set forward or backward slide backward or forward, the left and right pins 370, 371 will push the front position located inside the elongated hole 313. The protrusion 314 and the rear position are determined to determine the protrusion 315 so as to move along the rear end or front end of the elongated hole 313 . Accordingly, when the left and right cantilever arms 311, 312 slide along the front and rear directions, the front position determination protrusion 314 and the rear position determination protrusion 315 are exerted by the left and right pins 370, 371. pressure, the elongated hole 313 will be elastically deformed. The elongated hole 316 allows elastic deformation of the elongated hole 313 to improve the durability of the left and right cantilevers 311 , 312 .

[0061] The left and right cantilevers 311 , 312 are connected to the flange 330 through the left and right pins 370 , 371 , and can slide forward and backward, thereby changing the position of the nozzle 160 . like image 3 and Figure 4 as shown, image 3 is a schematic diagram of the state of the cleaning pad P1 with a thickness of t1; Figure 4 is a schematic side view of the state of using the cleaning pad P2 with a thickness of t2. Here, the thickness t2 is greater than the thickness t1 (t1 image 3 and Figure 4 As shown, the distances d1 and d2 between the nozzle suction port 163 located at the lower end of the nozzle cover 162 and the ground, according to the thickness of the cleaning pad, will change when the left and right cantilever arms 311, 312 slide forward and backward. is the same value, ie, d1=d2. Accordingly, according to the thickness of the cleaning pad used, a certain height between the nozzle suction port 163 and the ground is always maintained at 2 mm in the present invention to ensure the best suction effect.

[0062] The bracket 350 disposed on the joint 300 will be described in detail below.

[0063] like Figure 1~Figure 4 As shown, the bracket 350 is located on the upper side of the left and right flanges 331, 332, and passes through the left and right pins 370, 371 to connect with the left and right cantilevers 311, 312 and the left and right The flanges 331, 332 are connected to each other.

[0064] Described support 350 comprises following structure: be located at the middle position, be the support plate 351 of quadrilateral; The lower support 355 that is interconnected with the described flange that protrudes from the lower end of described support plate 351 along the downward direction; The upper ends of the bracket plates 351 protrude upwardly and are connected to the housings 200 for supporting the upper brackets 354 of the housings 200 .

[0065] In the bracket 350 , the central rotation axis of the upper bracket 354 for connecting the housing 200 forms a right angle with the central rotation axis of the lower bracket 355 , which is in the shape of a ball joint 300 .

[0066] like figure 2 As shown, the support plate 351 is located in the middle of the support 350 , and the cross section of the support plate is a quadrangle. The inside of the support plate 351 is provided with a circular opening into which a hose 400 for guiding the suction hose can be inserted. The lower bracket 355 protrudes from the lower end of the bracket plate 351 , and the upper bracket 354 is disposed on the upper end.

[0067] Protrude from the lower end of the bracket plate 351 along the downward direction with two quadrilateral described lower brackets 355, and on the lower brackets 355 are also provided with the left and right pins 370, 371 and The left and right flanges 331 , 332 are connected to each other by a circular through hole 358 .

[0068] Two quadrangular upper brackets 354 protrude from the upper end of the bracket plate 351 in the upward direction, and a cylindrical short rotating shaft protrudes from the inside of the upper bracket 354 to communicate with the housing. 200 are connected to each other, and make the casing 200 turn left and right.

[0069] like Figure 2~Figure 4 As shown, the left and right pins 370 , 371 connect the left and right cantilevers 311 , 312 and the bracket 350 to the left and right flanges 331 , 332 . like figure 2 As shown, the left and right pins 370, 371 include the through holes 334 that can pass through the left and right flanges 331, 332, the through holes 358 of the lower bracket 355, and the left and right cantilevers 311, 312. Behind the elongated hole 313 are connected cylindrical plugs 370a, 371a and circular plugs 370b, 371b.

[0070] Since the left and right pins 370, 371 are respectively pressed by the front position determining protrusion 314 and the rear position determining protrusion 315 provided inside the left and right cantilever arms 311, 312, the When the suspension arms 311, 312 slide forward and backward, the left and right suspension arms 311, 312 are elastically deformed. Therefore, the size and material of the left and right pins 370, 371 are determined accordingly.

[0071] As described above, the left and right cantilever arms 310 function as front and rear sliding members that slide back and forth according to the structure of the elongated hole 313 and the linear guide 333 . Therefore, it is convenient to replace the cleaning pad, and according to the thickness of the cleaning pad, a certain distance between the ground and the nozzle suction port 163 can be maintained to obtain equal suction. Because the distance is too long, the suction force will be reduced, thereby reducing the dust collection efficiency; if the distance is too short, it will be adsorbed on the ground, making it difficult to move forward and backward.

[0072] The joint is arranged at an eccentric e position between the front end of the mop head 110 and the center c of the mop head 110. The reason why the joint 300 maintains such a position is because the structure of the joint 300 Among the elements, the left and right flanges 331 , 332 are located between the front end of the mop head 110 and the center of the mop head 110 . like image 3 As shown, through the eccentric positions of the left and right flanges 331, 332, the left and right flanges 331, 332 are used to connect the left and right cantilevers 311, 312 and the bracket 350 and the left and right flanges 331, 332. The positions of the pins 370 , 371 will be offset from the center c of the mop head 110 by a distance e.

[0073] Accordingly, the forward tilting of the center of gravity caused by the weight of the nozzle nozzle 160 arranged in front of the mop head 110 can be effectively prevented, so as to alleviate the phenomenon that the mop head lifts up when the housing 200 is rotated back and forth. .

[0074] In addition, with a structure in which water is directly supplied to the cleaning pad through the water supply device 140, the wet wipe is used as a cleaning pad of the vacuum cleaner. At this time, due to the excessive friction between the wet rag and the ground, when the vacuum cleaner is pulled backward, the possibility of lifting the front of the vacuum cleaner will also increase, but if it is an eccentric structure, it can be contained to the greatest extent. This lifting phenomenon.

[0075] It is stated in advance that the technology of the present invention is not limited to the specific preferred embodiment, as long as it does not depart from the gist of the present invention applied within the scope of the application, anyone with general knowledge in the technical field to which the present invention belongs can carry out There are various modifications, and such changes all belong to the application scope of the present invention.
