DETAILED DESCRIPTION

[0049] Embodiments of the present invention are described in detail below, examples of which 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 intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0050] Combination Figures 1 to 24 According to an embodiment of the present invention, the nozzle unit 10 includes a nozzle body 11 and a connecting arm 20, wherein the first end of the connecting arm 20 is connected to the nozzle body 11, and the connecting arm 20 is rotatable around the circumference of the nozzle body 11, wherein a plurality of nozzle units 10 can be spliced ​​to form a larger structure to provide a larger suction area, and at this time, the second end of the connecting arm 20 can be connected to an adjacent nozzle unit 10. In other words, a plurality of nozzle units 10 can be connected via the connecting arm 20.

[0051] During use, the nozzle unit 10 can be used alone to clean the road surface, etc., or multiple nozzle units 10 can be connected together through the connecting arm 20 to form a large nozzle module 100, thereby increasing the effective cleaning area. In addition, since the connecting arm 20 can rotate around the circumference of the nozzle body 11, multiple nozzle units 10 can have a variety of different splicing methods to meet different splicing requirements.

[0052] According to the suction nozzle unit 10 of the embodiment of the present invention, the suction nozzle unit 10 has a connecting arm 20, and a plurality of suction nozzle units 10 can be combined together through the connecting arm 20, so that a larger suction nozzle module 100 is formed by splicing a plurality of suction nozzle units 10 to provide a larger working area and improve the road cleaning effect. Moreover, the suction nozzle unit 10 in the present application can also be used alone to meet different working requirements and improve the application range and cleaning effect of cleaning equipment (such as sanitation equipment 1000, floor scrubber, etc.) having the suction nozzle unit 10.

[0053] The plurality of nozzle units 10 are spliced ​​in the horizontal direction, and adjacent nozzle units 10 are connected via a connecting arm 20 ; the connecting arm 20 is connected between two adjacent nozzle units 10 .

[0054] like Figure 1 and Figure 2In some embodiments of the present invention, the nozzle body 11 may include a suction cup 111 and a wind tube 112, the suction cup 111 has a dust suction chamber 107, the wind tube 112 is connected to the suction cup 111 and communicates with the dust suction chamber 107, and the wind tube 112 may be connected through a suction structure to generate a negative pressure in the dust suction chamber 107, thereby sucking up garbage, dust, etc., so as to achieve the purpose of cleaning the road surface, and the suction cups 111 of multiple suction nozzle units 10 may be spliced ​​in the horizontal direction through a connecting arm 20. Among them, the wind tube 112 may extend in the up and down direction, and the lower end of the wind tube 112 is connected to the suction cup 111, and the wind tube 112 is communicated with the dust suction chamber 107, the first end of the connecting arm 20 is connected to the wind tube 112, and the second end of the connecting arm 20 is used for splicing between multiple suction nozzle units 10, and the connecting arm 20 is rotatable around the circumference of the wind tube 112. When multiple suction cups 111 are spliced ​​together, the connection between different suction cups 111 can be achieved through the connecting arm 20, and because the connecting arm 20 is rotatable, the matching structures of adjacent suction cups 111 can be different. Multiple suction cup 111 units can be spliced ​​into multiple rows, and the multiple rows of suction cup 111 units can be arranged relatively or staggered.

[0055] In the present invention, the suction nozzle body 11 can be used for collecting road garbage in a small area. The design width of a single suction nozzle body 11 may not exceed 500 mm, preferably 250 mm or 500 mm. The diameter of the wind tube 112 should be determined to adapt to the dust suction chamber 107 on the suction nozzle body 11 and the wind loss of the pneumatic conveying system. According to empirical analysis, the diameter of the wind tube 112 is preferably 80 mm, 120 mm, 160 mm, etc. Of course, the above description of the width of the suction nozzle body 11, the diameter of the wind tube 112, etc. are only some embodiments of the present invention, and are not intended to limit the scope of protection of the present invention.

[0056] Combination Figure 1 and Fig. 9 In some embodiments of the present invention, the nozzle body 11 may include a limit turntable 1121, which may be disposed on the wind tube 112 and arranged around the wind tube 112, and the limit turntable 1121 is relatively fixed to the wind tube 112 in the circumferential direction of the wind tube 112, that is, the limit turntable 1121 is fixedly connected to the wind tube 112. The limit turntable 1121 is vertically opposite to the first end of the connecting arm 20, and a plurality of limit grooves 103 are provided on the limit turntable 1121, and the plurality of limit grooves 103 may be arranged to be spaced around the circumference of the wind tube 112, and the limit turntable 1121 may be vertically opposite to the first end of the connecting arm 20.

[0057] For example, the limiting turntable 1121 can be welded below the boss 1122 on the wind tube 112, and the pin assembly 22 on the connecting arm 20 can be used to limit and release the connecting arm 20, so that the connecting arm 20 can rotate around the wind tube 112, so that the connecting arm 20 can adjust the angle according to the needs; it can also be fixed by the pin assembly 22 on the connecting arm 20. In other words, the first end of the connecting arm 20 is provided with a pin assembly 22, and the pin assembly 22 can be removably embedded in the limiting groove 103 to circumferentially limit the connecting arm 20. When the pin assembly 22 is embedded in the limiting groove 103, the connecting arm 20 can be circumferentially limited, and the connecting arm 20 is relatively stationary with the wind tube 112 in the circumferential direction of the wind tube 112; when the position of the connecting arm 20 needs to be adjusted, the pin assembly 22 can be removed from the limiting groove 103 to adjust the connecting arm 20 circumferentially, so that multiple nozzle units 10 can be combined in different arrangements.

[0058] Among them, the pin assembly 22 may contain a third elastic member 223 and a positioning pin 224. When not in operation, the positioning pin 224 is in an extended state and can be embedded in the limit turntable 1121, which can prevent the mounting seat from accidentally rotating during the rotation process, causing safety hazards. When rotation is required, the operator only needs to push the positioning pin 224 upward, which is easy to operate. In combination with the above, the pin assembly 22 can be driven manually to disengage from the limit slot 103. In addition, other methods can also be used to achieve the disengagement of the pin assembly 22.

[0059] See also Fig.15 The pin assembly 22 may include a third cylinder 221, a piston 222, a third elastic member 223 and a positioning pin 224. The third cylinder 221 is fixedly connected to or integrated with the connecting arm 20. The third cylinder 221 has a cavity 203, and a piston hole 202 is provided on the third cylinder 221. The piston hole 202 is provided on the end surface of the third cylinder 221, wherein the piston hole 202 communicates with the cavity 203, and the piston 222 is movably provided in the cavity 203 along the axial direction of the third cylinder 221. The positioning pin 224 is connected to the piston 222 and can pass through the piston hole 202. The third elastic member 223 is respectively connected to the piston 222 and the third cylinder 221, and has a force to move the piston 222 toward the piston hole 202, so that the positioning pin 224 extends. During use, the third elastic member 223 can apply force to the piston 222 so that the positioning pin 224 can be stably embedded in the corresponding limiting groove 103, thereby realizing a stable connection between the connecting arm 20 and the limiting turntable 1121. When the positioning pin 224 needs to withdraw from the limiting groove 103, the positioning pin 224 can be manually driven to withdraw from the limiting groove 103.

[0060] In addition, in some embodiments of the present invention, the nozzle unit 10 also includes a connecting seat 12, which is rotatably sleeved on the outside of the wind tube 112, and the connecting arm 20 is a movable telescopic arm, and the first end of the connecting arm 20 is provided with a first pitching movable joint portion 21, and the first end of the connecting arm 20 is connected to the connecting seat 12 through the first pitching movable joint portion 21, so that the second end of the connecting arm 20 can swing in the up and down direction. In this way, the relative floating between the interconnected nozzle units 10 can be facilitated to adapt to different ground surfaces. In addition, the connecting arms 20 of two adjacent nozzle units 10 can be connected together to form a bridging arm, and the two ends of the bridging arm are respectively provided with a first pitching movable joint portion 21 to connect the connecting seats 12 of the two adjacent nozzle units 10. Among them, the first pitching movable joint portion 21 is used for the connecting arm 20 to be swingably connected to the connecting seat 12 in the up and down direction.

[0061] Specifically, the multiple suction nozzle units 10 in the present invention can be connected by a connecting arm 20, and two adjacent suction nozzle units 10 can be arranged to be relatively liftable in the up and down directions. The connecting arm 20 can swingably connect the corresponding suction nozzle units 10 in the up and down directions. Through the lifting and lowering of the suction nozzle units 10, it is possible to clean uneven roads and improve the cleaning effect. Moreover, the rotation of the connecting arm 20 in the up and down directions can allow the two suction nozzle units 10 to have freedom in the up and down directions, thereby facilitating the relative lifting and lowering between the two suction nozzle units 10 and improving the stability of the suction nozzle units 10 during the lifting and lowering process.

[0062] The first end of the connecting arm 20 can adopt a first pitch movable joint portion 21 formed by a "shaft portion + elastic member + shaft portion" structure, so as to be hinged with the connecting seat 12. This structure can be installed without any tools; the second end of the connecting arm 20 is connected to a flange seat 233. Two adjacent nozzle units 10 are connected by two connecting arms 20, and the two connecting arms 20 are connected by a flange seat 233, and the first pitch movable joint portions 21 of the two connecting arms 20 are respectively connected to the connecting seats 12 of the two nozzle units 10, thereby realizing the connection of the connecting seats 12 of the two nozzle units 10. Of course, in addition to the above-mentioned pivot connection structure, the first pitch movable joint portion 21 can also be a movable connection structure with up and down swinging freedom, such as a ball joint seat, and the present application is not limited to this.

[0063] Combination Fig.10 , Fig.12 as well as Fig.14A pin hole 201 is provided on the first pitch movable joint 21, and a locking mechanism 24 is provided on the connecting seat 12. The locking mechanism 24 can be switched between a locking position and a releasing position. The locking mechanism 24 is inserted into the pin hole 201 in the locking position to limit the up and down swinging of the first pitch movable joint 21, that is, to limit the freedom of the up and down swinging of the first pitch movable joint 21, so that the second end of the connecting arm 20 cannot swing in the up and down direction; the locking mechanism 24 is disengaged from the pin hole 201 in the releasing position so that the first pitch movable joint 21 can swing up and down relative to the connecting seat 12, so that the connecting arm 20 can be swingably connected to the corresponding suction nozzle unit 10 in the up and down direction. By setting up the locking mechanism 24, the locking and releasing of the first pitch movable joint 21 can be achieved, so as to adjust the swing of the connecting arm 20. During use, the locking mechanism 24 can be placed in the released position so that the connecting arm 20 can swing up and down stably, so as to adjust the multiple suction nozzle units 10 spliced ​​to each other; after use, the locking mechanism 24 can be used to lock the first pitch movable joint 21, so as to lift the multiple suction nozzle units, etc.

[0064] Among them, Fig.16 As shown, the locking mechanism 24 includes a first cylinder 241, a latch 244 and a first elastic member 245. The first cylinder 241 is fixedly connected to the connecting seat 12. The first cylinder 241 has a cavity 242 and a water inlet 243 connected to the cavity 242. The latch 244 is movably connected to the first cylinder 241 so as to be extendable and retractable, and is suitable for being inserted into the latch hole 201 when the latch 244 is extended. The first elastic member 245 is connected to the latch 244 and is used to drive the latch 244 to extend out of the first cylinder 241 and be inserted into the latch hole 201. Among them, water can be supplied to the first cylinder 241 through the water inlet to disengage the latch 244 from the latch hole 201, and the locking mechanism 24 is in the release position at this time. When the water pressure is lost, the latch 244 can be inserted into the latch hole 201 under the driving action of the first elastic member 245, and the locking mechanism 24 is in the locking position at this time. In this way, water can be supplied to the first barrel 241 during use of the nozzle unit, but no water is supplied to the first barrel 241 after use, so that the state of the locking mechanism can be adjusted according to whether the nozzle unit is in use.

[0065] The nozzle unit 10 further includes a dust reduction nozzle 141 and a dust reduction water pipe 142 . The dust reduction water pipe 142 is connected to the dust reduction nozzle 141 to spray water into the air duct 112 , and the dust reduction water pipe 142 is connected to the water inlet 243 to drive the latch 244 out of the latch hole 201 .

[0066] In addition, by providing the water inlet 243, when water is supplied to the water inlet 243, the pressure of the water entering the first cylinder 241 can maintain the latch 244 to exit the latch hole 201, so as to facilitate the stable rotation between the connecting arm and the mounting seat. When the nozzle unit is not working, water can be not supplied to the water inlet 243, and the second elastic member can be used to drive the latch 244 to extend, so as to facilitate the relatively fixed connection between the connecting arm and the mounting seat.

[0067] Specifically, Fig.16 As shown, the locking mechanism 24 includes a first cylinder 241, a latch 244 and a first elastic member 245. The first cylinder 241 is fixedly connected to the connecting seat 12. The first cylinder 241 has a cavity 242 and a water inlet 243 and a latch extension port connected to the cavity 242. The dust suppression water pipe 142 is connected to the cavity 242 through the water inlet 243, and can flow water into the cavity 242 when the dust suppression nozzle 141 is working. The latch 244 is in the shape of a piston rod and includes a connected piston portion and a piston rod portion. The latch 244 is arranged in the cavity 242. The first elastic member 245 is arranged in the cavity 242 and its two ends are respectively connected to the piston portion of the latch 244 and the first cylinder 241. The water inlet 243 and the latch extension port are both located on one side of the piston rod portion of the latch 244. The piston rod portion of the latch 244 can extend out of the first cylinder 241 or retract into the first cylinder 241 through the latch extension port under the action of the water supply in the first elastic member 245 and the dust suppression water pipe 142.

[0068] Combination Fig. 9 , Fig.15 and Fig.16 In some embodiments of the present invention, the nozzle unit 10 further includes a dust reduction nozzle 141 and a dust reduction water pipe 142, and the dust reduction nozzle 141 is suitable for spraying water toward the wind tube 112. Through the dust reduction nozzle 141, the purpose of spraying water into the wind tube 112 to reduce dust can be achieved, so as to improve the effect of road cleaning, reduce secondary pollution, and reduce the impact on the surrounding environment during the cleaning process. The dust reduction water pipe 142 can be connected to the dust reduction nozzle 141, and the dust reduction water pipe 142 can also be connected to the water inlet 243 to drive the first shaft portion 213 to maintain a state of extending out of the second cylinder 211 and embedded in the mounting hole 108. That is to say, when the nozzle unit 10 is working, the water pressure can be used to maintain the extended state of the first shaft portion 213, and when the nozzle unit 10 stops working, the water pressure can be unloaded to facilitate the adjustment of the splicing method of multiple nozzle units 20.

[0069] The dust suppression nozzle 141 is fixedly connected to the wind tube 112. The dust suppression water pipe 142 is connected to the dust suppression nozzle 141 to supply water to the dust suppression nozzle 141, wherein the wind tube 112 is provided with a water spray hole 109, the dust suppression nozzle 141 is opposite to the water spray hole 109, and the dust suppression water pipe 142 can be arranged in a ring shape and extend around the wind tube 112 to connect a plurality of dust suppression nozzles 141 arranged at intervals around the wind tube 112, wherein the dust suppression water pipe 142 can be integrated with the mounting seat. A first seat body can be set on the annular dust suppression water pipe 142 to install a nozzle. The first seat body can be welded on the wind cylinder 112, and the nozzle position is welded corresponding to the water spray hole 109 to ensure that water with stable pressure at the nozzle passes through the water spray hole 109 on the wind cylinder 112 to clean the wind cylinder 112 and the inner wall of the corrugated pipe. At the same time, a water outlet with a smaller diameter is arranged on the dust suppression water pipe 142 (which can be a steel pipe), and is connected to the water inlet 243 of the locking mechanism on the connecting arm 20 described below through a smaller water pipe.

[0070] In addition, in combination with the above, the connected hose is a rubber hose, and the connection form is a threaded connection, which can be quickly twisted and installed simply and conveniently. When the nozzle unit 10 is working, the dust suppression water pipe 142 will be fed with clean water of a certain pressure, and the clean water will be sprayed out through the dust suppression nozzle 141 on the dust suppression water pipe 142 to suppress dust; at the same time, the water outlet on the dust suppression water pipe 142 is passed into the chamber in the first pitch movable joint part 21, so that the first shaft part is maintained in a state of extending out of the second cylinder and embedded in the corresponding installation hole.

[0071] Specifically, if Fig. 9 , Fig.12 , Fig.13 as well as Fig.14 , Fig.17 The first pitch movable joint part 21 may include a second cylinder 211, a first shaft 213 and a second elastic member 212. The second cylinder 211 may be fixedly connected to the connecting arm 20, and a cavity may be provided in the second cylinder 211, and a pin hole 201 is provided on the peripheral wall of the second cylinder 211. The first shaft 213 is telescopically provided on the second cylinder 211 along the axial direction of the second cylinder 211, and the first shaft is telescopically connected to the end of the second cylinder, and the second elastic member 212 can drive the first shaft 213 to extend out of the second cylinder 211. In addition, the first shaft 213 may be provided at both axial ends of the second cylinder 211, and the second elastic member 212 may be supported between the two first shafts 213 to facilitate the installation and removal of the connecting arm 20 and the mounting seat.

[0072] In addition, an ear seat 121 may be provided on the connection seat 12, and a mounting hole 108 may be provided on the ear seat 121. In combination with the above-mentioned embodiment, the first shaft portion may be embedded in the mounting hole when it extends out of the second cylinder. The connection seat 12 may be provided with two ear seats arranged opposite to each other, and the first pitch movable joint portion 21 is arranged between the two ear seats, and both ends of the second cylinder are connected to the first shaft portion, so that when the two first shaft portions extend out, they can be respectively embedded in the mounting holes on the corresponding ear seats.

[0073] like Figure 1 In some embodiments of the present invention, the air cylinder 112 extends in the up-down direction, and the lower end of the air cylinder 112 is connected to the suction cup 111, and the connecting seat 12 is rotatably sleeved on the outer side of the air cylinder 112. A bearing may be provided between the connecting seat 12 and the air cylinder 112. Of course, a bearing may not be provided between the connecting seat 12 and the air cylinder 112. It is only necessary to enable the connecting seat 12 and the air cylinder 112 to rotate relative to each other. When multiple suction nozzle units 10 are spliced, the second suction nozzle unit 10 can be provided at the front side, rear side, left side, right side or inclined direction of the suction nozzle unit 10. Therefore, by rotatably sleeved on the air cylinder 112 by the connecting seat 12, the direction and position of the connecting seat 12 can be adjusted to adapt to different splicing methods of multiple suction nozzle units 10.

[0074] like Fig.12 and Fig.13 In some embodiments of the present invention, in order to facilitate the use of the connecting arm 20 to adjust the positions of the mutually connected nozzle units 10, the connecting arm 20 can be set to be retractable in length. For example, the connecting arm 20 can include a first connecting portion 232 and a second connecting portion 231. The first connecting portion 232 and the second connecting portion 231 are retractably connected. The first end of the connecting arm 20 is constructed on the first connecting portion 232, and the second end of the connecting arm 20 is constructed on the second connecting portion 231. In this way, when the splicing mode of the multiple nozzle units 10 is adjusted, the length of the connecting arm 20 can be adaptively adjusted to improve the connection stability between the multiple nozzle units 10.

[0075] In addition, the connecting arm 20 can adopt a rectangular steel pipe structure, which is not easy to rotate with each other compared with a circular steel pipe structure, which affects the use. In addition, the connecting arm 20 can include a first connecting portion 232 and a second connecting portion 231, the second connecting portion 231 is movably sleeved in the first connecting portion 232 along the axial direction, and the outer peripheral surface of the second connecting portion 231 is provided with a groove extending along the axial direction of the connecting arm 20, and the first connecting portion 232 is provided with a rib, which extends along the axial direction of the connecting arm 20 and is suitable for embedding into the groove. The first connecting portion 232 is provided with a hole that can just install a spring buckle to ensure the normal operation of the spring buckle and prevent the connecting arm 20 from being disengaged. The end of the first connecting portion 232 can be provided with a pin assembly 22 for hinged connection with the connecting seat 12; the end of the second connecting portion 231 is provided with a flange seat 233, and the connecting arms 20 of different suction nozzle units 10 can be connected together through the flange seat 233, and the two connecting arms 20 are respectively connected to the connecting seats 12 of the two nozzle units. The two flange seats 233 can be connected by bolts for quick assembly, or they can be installed in a self-designed connection form.

[0076] In addition, the aforementioned pin assembly 22 can be arranged at the end of the first connecting portion 232, and is used to insert and fix the positioning pin 224 when it is in the extended state to prevent the connecting arm 20 from rotating, so that when the entire suction nozzle module 100 is lifted, a stable connection is formed between the suction nozzle units 10 to form a whole. When the suction nozzle module 100 is lifted, no mutual slippage will occur to cause damage to the suction nozzle unit 10; when the suction nozzle unit 10 is working, the positioning pin 224 is retracted, and the connecting arms 20 can be flexibly rotated to achieve cleaning operations on complex roads and adapt to obstacles of different heights.

[0077] In addition, the second end of the connecting arm 20 is provided with a second pitching movable joint 25 and a flange seat 233, and the second end of the connecting arm 20 is connected to the flange seat 233 via the second pitching movable joint 25, so that the connecting arm 20 can swing in the up and down direction relative to the flange seat 233. This can further improve the stability of the multiple suction nozzle units 10 connected by the connecting arm 20, facilitate the suction nozzle module composed of the suction nozzle unit 10 to adapt to different road conditions, and improve the application range of the sanitation equipment with the suction nozzle unit.

[0078] Combination Figures 1 to 3In some embodiments of the present invention, the suction cup 111 includes a bottom plate 1111 and a frame, the air cylinder 112 is connected to the bottom plate 1111, the frame is connected to the bottom plate 1111, and the frame surrounds the dust suction chamber 107 below the bottom plate 1111, and the nozzle unit 10 may also include a connector, which can be used for the upper and lower movable connection between multiple nozzle bodies 11, that is, multiple nozzle bodies 11 can be spliced ​​together through the connector, and multiple nozzle bodies 11 can be relatively moved up and down. Among them, the connector can be arranged on the bottom plate 1111, and can also be arranged on the frame. Optionally, the connector is arranged on the outside of the frame. When the connector is arranged on the outside of the frame, the stable splicing of multiple suction cups 111 can be achieved, the stability of the connection between the multiple suction cups 111 is guaranteed, and the connector is easy to disassemble and assemble, so as to achieve the rapid splicing of multiple suction cups 111.

[0079] Optionally, connectors are provided on the outer sides of the two opposite side walls of the frame, and connectors can also be provided on the outer sides of the four side walls of the frame. By providing connectors, stable splicing between multiple nozzle units 10 can be achieved, and the structural stability of the nozzle units 10 after splicing can be improved. In addition, when connectors are provided on the opposite two sides, multiple nozzle units 10 can be arranged in a predetermined direction at one time. When connectors are provided on all four side walls of the frame, multiple nozzle units 10 can have more splicing methods to improve cleaning efficiency and effect.

[0080] For example, the frame includes a side panel 1112, and the left and right sides of the bottom plate 1111 are connected to the side panels 1112, the dust suction chamber 107 is located between the side panels 1112 on both sides of the bottom plate 1111, and the outer side of the side panel 1112 is connected to a connector, and the connectors provided on the side panels 1112 on the left and right sides can realize the splicing of multiple suction nozzle units 10 along the left and right directions. Of course, the side panels 1112 can also be provided on the front and rear sides of the bottom plate 1111. In addition, the frame also includes a running wheel mounting seat 1113, and the front and rear sides of the bottom plate 1111 are connected to the running wheel mounting seat 1113, and the outer side of the running wheel mounting seat 1113 is connected to a connector. The connectors provided on the running wheel mounting seats 1113 on the front and rear sides can realize the splicing of multiple suction nozzle units 10 along the front and rear directions.

[0081] The suction cup 111 of the present invention can be configured into a polygon such as a triangle, a square, a pentagon, or a circle, an ellipse, or other shapes. The shape of the suction cup 111 can be adjusted or selected according to different usage conditions. Figures 1 to 3In some embodiments of the present invention, the suction cup 111 is arranged in a square shape, and the side panels 1112 on the left and right sides of the suction cup 111 are provided with connectors; for another example, the running wheel mounting seats 1113 on the front and rear sides of the suction cup 111 are provided with connectors. In addition, connectors can be provided on the side panels 1112 on the left and right sides of the suction cup 111 and on the running wheel mounting seats 1113 on the front and rear sides of the suction cup 111. Multiple suction cups 111 can be spliced ​​not only in the left-right direction, but also in the front-back direction, and can also be spliced ​​in the left-right direction and the front-back direction, so as to provide more splicing solutions and achieve a wider range of cleaning.

[0082] Among them, walking wheel mounting seats 1113 can be set on the left front side, right front side, left rear side and right rear side of the suction cup 111 to realize the stable movement of the suction nozzle unit 10, and the aforementioned connecting parts are set on the outer side of each walking wheel mounting seat 1113 to realize a more stable connection between multiple suction cups 111. In addition, a suction port is constructed between the walking wheel mounting seats 1113 on the front side of the suction cup 111; a suction port can also be constructed between the walking wheel mounting seats 1113 on the rear side of the suction cup 111. In addition, a sand blocking mechanism 13 can be set to cover and open the suction port to improve the cleaning effect.

[0083] The walking wheel 102 can be installed on the walking wheel mounting seat 1113. The walking wheel 102 can be an inflatable rubber wheel. Different from the traditional polyurethane or rubber solid walking wheel 102, the inflatable walking wheel 102 has obvious shock absorption effect, light weight, and a hub diameter larger than that of the general walking wheel 102, so that larger obstacles can be crossed during the obstacle crossing process; the walking wheel 102 is arranged on the inner side of the cavity below the bottom plate 1111, which saves more space for the suction nozzle module 100 and does not affect the normal operation of the suction nozzle unit 10. The suction wheel is installed at the double-formed plywood at the four corners of the bottom plate 1111, which effectively prevents dust from entering and causing accelerated wear of the walking wheel 102, and the inner plywood is provided with a waist hole. When the walking wheel 102 is worn, it can be adjusted to extend the service life of the suction nozzle body 11.

[0084] The connector in the present invention can have many different forms, as long as it can realize the splicing of multiple suction cups 111. For example, the connector can be set as a bolt connection structure, a snap connection structure, an adhesive structure, etc. The present invention provides some specific implementation methods below to realize the connection between multiple suction cups 111, but this is not a limitation on the scope of protection of the present invention.

[0085] Combination Figures 1 to 7In some embodiments of the present invention, the connector includes a mounting plate 113, which is connected to the outside of the frame. A slide groove 104 and a slider 105 can be provided on the outer surface of the mounting plate 113. The slide groove 104 and the slider 105 both extend in the up-down direction, and the cross section of the slider 105 is "T"-shaped. The cross section of the slider 105 is adapted to the cross section of the slide groove 104. When the slide grooves 104 of different suction cups 111 cooperate with the slider 105, the slider 105 can be prevented from falling out of the slide groove 104 in the horizontal direction. During use, multiple suction cups 111 are spliced ​​together through the cooperation of the slide grooves 104 and the slider 105. For example, the slide groove 104 on the first suction cup 111 is spliced ​​with the slider 105 on the second suction cup 111; and the slider 105 on the first suction cup 111 is spliced ​​with the slide groove 104 on the second suction cup 111, so as to achieve a stable connection between the two suction cups 111.

[0086] In addition, the mounting plate 113 can be integrated with the frame, or in other words, the aforementioned slide groove 104 and slider 105 can be directly arranged on the side plate 1112 and the walking wheel mounting seat 1113. The mounting plate 113 can also be arranged to be slidably connected to the frame in the up-down direction. During use, the connecting piece can be lifted and lowered relative to the frame in the up-down direction. When multiple suction cups 111 are spliced ​​by the connecting piece, the multiple suction cups 111 can float in the up-down direction relatively. Especially when there is a certain height difference on the road surface, the multiple suction cups 111 can float up and down relatively to achieve a better cleaning effect, and can also provide a certain obstacle crossing capability for the nozzle module 100.

[0087] Among them, a guide rib 101 along the up-down direction can be provided on the frame, and a guide groove 106 can be provided on the mounting plate 113, and the guide groove 106 can extend in the up-down direction, and the guide rib 101 is embedded in the guide groove 106, and the mounting plate 113 can slide in the up-down direction relative to the inner plate 1112. Of course, the guide rib 101 can also be provided on the mounting plate 113, and the guide groove 106 can be provided on the frame. In addition, other methods can also be used to realize the sliding of the mounting plate 113 in the up-down direction relative to the frame. The above description of the connection method between the mounting plate 113 and the frame is only some embodiments of the present invention, and is not a limitation on the protection scope of the present invention. In addition, a guide block 1131 can be provided on the inner side of the mounting plate 113, and notches are respectively provided at both ends of the guide block 1131, and a guide groove 106 is constructed between the notch of the guide block 1131 and the mounting plate 113.

[0088] In combination with the above, the mounting plate 113 can be configured to have a double-layer slide groove 104 structure, that is, a slide groove 104 is provided on the outer side of the mounting plate 113 to realize the splicing between multiple nozzle units 10; a guide groove 106 is provided on the inner side of the mounting plate 113 to realize the slidable connection of the frame in the up and down directions.

[0089] The mounting plate 113 can be arranged on the left and right sides of the suction cup 111 and on the single-sided outer side of the walking wheel mounting seat 1113. The double-layer slide grooves 104 on the mounting plates 113 on the opposite sides of the suction cup 111 have different groove types. In order to complement each other, the slide grooves 104 between the two suction nozzle bodies 11 will not be misaligned when connected, and the reverse direction when the suction nozzle bodies 11 are installed between each other is avoided, which is easy to find errors during installation in time; the opening of the slide groove 104 is processed to protrude in the middle part so that the cross-section of the slide groove 104 has an internal width smaller than the opening width. The slide groove 104 is processed as a whole section so that the slide groove 104 can slide in both directions during the sliding process, and the slide grooves 104 do not interfere with each other. The first end of the slide groove 104 along the up and down direction is closed to avoid falling out during the mutual sliding process. The second end of the slide groove 104 along the up and down direction is open and not closed, which is convenient for installation between the suction nozzle bodies 11. A groove is constructed between the guide rib 101 on the frame and the surface of the frame, which is interlocked with the guide groove 106. Limit ribs are provided at the upper and lower ends of the guide rib 101 to prevent the mounting plate 113 from escaping from the frame, and the upper and lower ends of the slide groove 104 are closed to prevent the mounting plate 113 from moving to the bottom of the nozzle body 11 to avoid damage to the mounting plate 113; the double-layer slide groove 104 design effectively increases the movement distance between the nozzle body 11, allows for a greater degree of obstacle crossing, and adapts to more uneven roads.

[0090] like Figure 2As shown, a suction port is provided at the front side and / or the rear side of the suction cup 111, and a sand blocking mechanism 13 may be provided. The sand blocking mechanism 13 may include a baffle 131 and an electric push rod 132. The baffle 131 is rotatably connected to the suction cup 111 and is rotatable between a position of blocking and opening the suction port. For example, the sand blocking mechanism may be arranged at the front side of the bottom plate 1111, and a relatively closed space is formed between the baffle 131, the bottom plate 1111 and the frame, so that when the whole is working, a relatively large negative pressure can be generated at the suction port, which is conducive to the suction nozzle unit 10 to suck up garbage. The baffle 131 preferably adopts a three-layer structure of "plywood + rubber sheet + plywood", that is, the rubber sheet is clamped by two layers of inner and outer plywood, wherein the inner plywood can be a steel plate body, which can ensure that the rubber sheet is not easy to fall off, and a transmission rod can be welded in the inner plywood of the sand retaining mechanism 13, so that the rubber sheet can rotate around the transmission rod; when the suction nozzle unit 10 is used for garbage with a large volume and a light weight, the rubber sheet in the baffle 131 is rotated in the direction of the wind tube 112 by controlling the electric push rod 132, so that the dust suction chamber 107 with a small volume and light weight is sucked into the dustbin, and then sucked into the garbage bin, effectively avoiding the accumulation of garbage outside the suction nozzle body 11, which affects the working efficiency. The control of the electric push rod 132 can be based on the addition of a camera to manually control the operation of the sand retaining mechanism, or it can be automatically identified and controlled by radar or other related sensors.

[0091] In addition, the slide groove 104 can be configured to be open at the first end along the up-down direction, and the shape of the slide groove 104 is adapted to the shape of the slide groove 104. During the connection process of the two suction cups 111, the slider 105 can be quickly inserted into the slide groove 104 along the up-down direction, and the relative positioning of the slider 105 and the slide groove 104 in the horizontal direction can be ensured, thereby improving the stability of the connection between the multiple suction cups 111.

[0092] Optionally, the length of the slider 105 in the vertical direction can be set to be shorter than the length of the chute 104 in the vertical direction. In this case, the slider 105 embedded in the chute 104 can also slide along the corresponding chute 104 in the vertical direction, so that the two mutually connected suction cups 111 can move relative to each other in the vertical direction to adjust the relative heights of different suction cups 111, thereby improving the cleaning effect on uneven roads. At the same time, the obstacle crossing ability of the nozzle module 100 composed of multiple nozzle units 10 is improved.

[0093] In addition, a plurality of slide grooves 104 and a plurality of sliders 105 may be provided on the mounting plate 113, and the plurality of slide grooves 104 are arranged at intervals along the circumference of the frame, and the plurality of sliders 105 are arranged at intervals along the circumference of the frame. Among them, the slider 105 may be arranged between two adjacent slide grooves 104; or the slide groove 104 may be arranged between two adjacent sliders 105. Optionally, the plurality of slide grooves 104 and the plurality of sliders 105 on the plurality of mounting plates 113 are arranged in an alternating manner. For example, on the mounting plates 113 provided on the left and right sides of the suction cup 111, the plurality of slide grooves 104 may be arranged at intervals along the front-back direction, the plurality of sliders 105 may be arranged at intervals along the front-back direction, and the slider 105 may be provided between two slide grooves 104; or the slide groove 104 is provided between two sliders 105. By providing a plurality of slide grooves 104 and a plurality of sliders 105, a stable connection between two suction cups 111 may be achieved, and more than two suction cups 111 may be connected together.

[0094] Optionally, in order to facilitate the connection between the two suction cups 111 through a connecting piece, the first end of the slide groove 104 in the up and down direction can be opened and the second end can be closed. After the slider 105 is inserted into the slide groove 104 in the up and down direction, the open end of the slide groove 104 can be closed to achieve the positioning of the slider 105, thereby achieving a stable connection of multiple suction cups 111. Specifically, in the present invention, the first end of the slide groove 104 in the up and down direction is open and can be blocked by a blocking piece.

[0095] In addition, the slide grooves 104 in the two connecting members for mutual connection can be set in a complementary form, that is, the slide groove 104 in the first connecting member can be set to a shape extending in the up-down direction and open at the lower end, and the slide groove 104 in the second connecting member can be set to a shape extending in the up-down direction and open at the upper end, so that the first connecting member can be assembled with the second connecting member from top to bottom, wherein during the assembly process: the lower end of the slide groove 104 in the first connecting member is opposite to the slider 105 in the second connecting member up and down; the slider 105 in the first connecting member is opposite to the upper end of the slide groove 104 in the second connecting member downward. Move the first connecting member from top to bottom, at this time, the slider 105 will slide into the corresponding slide groove 104 in the up-down direction, and the two nozzle units 10 can be connected through the connecting member.

[0096] In addition, the suction cup 111 of the present invention may be provided with multiple groups of connecting members, one group of connecting members being complementary to another group of connecting members, so that multiple suction cups 111 having the same structure can be stably installed by the method described above. The two groups of connecting members being complementary to each other can be provided on opposite sides of the suction cup 111 (or on the same side).

[0097] like Figure 1As shown, in some embodiments of the present invention, the air cylinder 112 extends in the up-down direction and the lower end is connected to the suction cup 111, and the connecting seat 12 is sleeved and fixedly connected to the air cylinder 112. Thus, the connecting seat 12 can be conveniently and stably installed, and when multiple suction cups 111 are spliced ​​together, the connecting seat 12 can be used to achieve a stable connection between the multiple connecting seats 12, thereby improving the stability of the connection between the multiple suction cups 111 spliced ​​together.

[0098] Optionally, the air duct 112 can be welded to the middle position of the bottom plate 1111. The air duct 112 can connect the dust suction chamber 107 in the suction cup 111 with the corrugated hose leading to the garbage bin. The air duct 112 has a "horn" appearance with a large bottom and a large bottom. It can effectively avoid the whistling sound of air vibration caused by the sudden change of the cross-sectional area when the airflow enters, and can also reduce the wind loss caused by the sudden change of the cross-sectional area. The outer side of the straight cylinder part of the air duct 112 is arranged with a boss 1122 for assembling the mounting seat, and a clamping groove and a clamping spring are arranged on the top to fix the inner sleeve ring of the mounting seat. There are multiple water spray holes 109 arranged above the clamping groove for dust reduction inside the air duct 112 to avoid dust from sticking to the inner side of the air duct 112 when there is a lot of dust, causing dirt that is difficult to clean. The top of the straight cylinder of the air duct 112 is fixedly connected to the retractable corrugated pipe through a clamp, and is connected to the fan through the garbage bin and the air duct to form a pneumatic conveying system to suck and pick up the dirty places on the ground.

[0099] In addition, in the present invention, the aforementioned nozzle units 10 can be combined to construct a nozzle module 100, thereby achieving cleaning in a wider range. To this end, the present invention also provides a nozzle module 100, which is formed by combining the aforementioned nozzle units 10.

[0100] Combination Figures 1 to 24 The nozzle module 100 according to the embodiment of the present invention comprises a plurality of nozzle units 10. The nozzle units 10 are according to the aforementioned nozzle units 10. The plurality of nozzle units 10 are spliced ​​in the horizontal direction, and the connecting arms 20 of adjacent nozzle units 10 are connected.

[0101] According to the nozzle module 100 of the embodiment of the present invention, the aforementioned nozzle units 10 can be spliced ​​together to form a larger nozzle module 100, thereby achieving cleaning in a larger range. Moreover, according to different cleaning range requirements, different numbers of nozzle units 10 can be rotated for splicing, which is convenient for use. In addition, through the connection of the connecting arm 20, the stability and structural strength of the connection between the nozzle units 10 can be effectively improved.

[0102] In some embodiments of the present invention, two adjacent suction nozzle units 10 can be relatively lifted and lowered in the up and down directions. In combination with the aforementioned embodiments, the connecting arm 20 is rotatably connected to the corresponding suction nozzle units 10 in the up and down directions. By lifting and lowering the suction nozzle units 10, it is possible to clean uneven roads and improve the cleaning effect. Moreover, the rotation of the connecting arm 20 in the up and down directions can allow the two suction nozzle units 10 to have freedom in the up and down directions, thereby facilitating the relative lifting of the two suction nozzle units 10 and improving the stability of the suction nozzle units 10 during the lifting process.

[0103] In addition, the connecting arm 20 of the present invention can be configured to be telescopic within a predetermined range. Since the interconnected nozzle units 10 need to float relatively in the up and down directions, there will be a small distance change between the connecting seats 12 of the two nozzle units 10. Therefore, setting the connecting arm 20 to be telescopic can ensure that the nozzle units 10 can move stably relative to each other. In addition, the connecting arm 20 can be configured to have a larger telescopic damping, thereby improving the connection strength between the nozzle units 10.

[0104] The connecting arm 20 can adopt a telescopic structure, which can make the nozzle unit 10 adaptively grow or shorten in length as the connection point changes during relative sliding. Two adjacent nozzle units 10 are connected by two connecting arms 20, and the two connecting arms 20 are connected by a flange seat 233, and the first pitch movable joints 21 of the two connecting arms 20 are respectively connected to the connection seats 12 of the two nozzle units 10, thereby realizing the connection of the connection seats 12 of the two nozzle units 10. The aforementioned second elastic member 212 and the third elastic member 223 can be springs or other structures.

[0105] like Fig. 20 and Fig.21 As shown, a plurality of the suction nozzle units 10 are spliced ​​into a plurality of rows arranged in the front-to-back direction, and the suction nozzle units 10 in two adjacent rows are opposite or staggered. When two rows of the suction nozzle module 100 composed of a plurality of suction nozzle units 10 are opposite, multiple cleanings can be achieved to improve the cleaning effect; in addition, when two rows of the plurality of suction nozzle units 10 are staggered, the suction nozzle units 10 in the rear row can be used to clean the position between the two suction nozzle units 10 in the front row, so as to effectively improve the cleaning efficiency and effect.

[0106] Combination Fig.10 , Fig.11 as well as Fig.18 and Fig.19 The nozzle module 100 also includes a side spray bar module 30, which is connected to the multiple nozzle units 10 and is arranged on the left and right sides of the multiple nozzle units 10, and can drive the garbage to gather toward the front side of the multiple nozzle units 10.

The connecting rod installation module is similar to other module structures, and an installation transition plate for up, down, left and right adjustment is provided to adapt to different vehicle body widths.

[0120] When the nozzle module 100 is assembled as a whole, multiple assembly structures can be used, such as Fig. 20 The "3+2" assembly shown in the figure can effectively avoid the problem that the front row cannot be cleaned due to the imprint of the walking wheel 102 due to structural limitations. Therefore, the cross assembly method is preferred to achieve the cleaning of the road surface without dead angles, and can also be connected according to different requirements. In addition, the nozzle module 100 can also be assembled in other ways, such as Fig.21 The “3+3” assembly shown in .

According to the analysis, the number of active components n = 5, the low pair constraint number P L =6, high pair constraint number; P H = 0, and the calculation shows that the degree of freedom is 3, so the connecting rod mechanism can be more flexible and the motion trajectory covers a wider range. When the nozzle module stops working, the positioning pins at both ends of the connecting arm are inserted and no longer rotate. The connecting arm is equivalent to a straight rod. Obviously, the degree of freedom is equal to 0. When the nozzle module 100 is lifted, it does not move, and the connecting rods are relatively still.

Specifically, the pneumatic conveying system of the whole vehicle is to rotate the transmission shaft of the auxiliary engine system 200I, and drive the fan system 200J to rotate through the rotation of the pulley to generate negative pressure, and then suck the water tank assembly 200K through the air duct to generate negative pressure in the water tank assembly 200K. A plurality of suction cylinders 112 are arranged in the water tank assembly 200K, and the suction cylinders 112 are connected to the bottom suction nozzle module 100 through a bellows, so that negative pressure is generated at the suction nozzle unit 10, thereby sucking up dirt or garbage on the ground. During overall operation, the "sweeping disc + suction nozzle module 100" operation mode can be adopted for stubborn stains on the road surface, that is, the left and right spray rod modules 30 clean the road surface, and according to the opposite rotation of the sweeping disc, the cleaned garbage is gathered to the center of the vehicle, and finally the garbage is sucked into the trash can by the suction nozzle module 100; during non-working hours, the suction nozzle module 100 and the left and right spray rod modules 30 are lifted by the hydraulic system 200F, so that the vehicle has a certain departure angle, making the whole vehicle more passable.
