DETAILED DESCRIPTION

[0033] The application will be further described below in conjunction with the drawings.

[0034] The embodiment of the application provides a dust collection head, which comprises a main housing and a roller brush assembly 100 and a side brush assembly 200 installed on the main housing, the side brush assembly 200 is located outside the end of the roller brush assembly 100, at least one end of the roller brush assembly 100 is provided with the side brush assembly 200, and the side brush assembly 200 comprises a brush head 240, the brush head 240 is used for sweeping dust in a corresponding area outside the end of the roller brush assembly 100 to a corresponding area of the roller brush assembly 100.

[0035] Specifically, as shown in the drawings Figure 1 and Figure 2As shown, the dust collecting head of the present application includes two dust sweeping parts, i.e. the side brush assembly 200 and the roller brush assembly 100, the roller brush assembly 100 is used for sweeping and collecting dust on large flat surfaces, and the side brush assembly 200 is mainly used for sweeping the side and corner positions that cannot be cleaned by the roller brush assembly 100. Specifically, since the dust collecting port of the dust collecting head corresponds to the roller brush assembly, the main function of the side brush assembly 200 is to sweep the dust on the side and corner positions to the corresponding area of the roller brush assembly 100, that is, to sweep the dust on the side to the middle. From the perspective of the user when using, that is, the rotation direction of the side brush assembly 200 arranged on the left side is clockwise, and the rotation direction of the side brush assembly 200 arranged on the right side is counterclockwise.

[0036] According to specific needs, the side brush assembly 200 can be arranged at both ends of the roller brush assembly 100; or only one side brush assembly 200 can be arranged, because the cleaning path is generally a rotary shape, and the side brush assembly 200 arranged on one side can also clean the other side of the site after rotation.

[0037] In one embodiment, the main housing is provided with a driving assembly for simultaneously driving the roller brush assembly 100 and the side brush assembly 200, the driving assembly includes a driving wheel 250 cooperating with the driving motor, and the driving wheel 250 simultaneously cooperates with the roller brush assembly 100 and the side brush assembly 200.

[0038] Specifically, based on the relative position design of the roller brush assembly 100 and the side brush assembly 200, the driving assembly is arranged at the end of the roller brush assembly 100, i.e. between the roller brush assembly 100 and the side brush assembly 200, the driving wheel 250 of the driving assembly can simultaneously cooperate with the roller brush assembly 100 and the side brush assembly 200, and then realize two-way output based on one power. The driving wheel 250 can adopt any one of a gear, a sprocket, a friction wheel, and a belt wheel, or the driving wheel 250 can be a composite wheel composed of multiple wheels.

[0039] In one embodiment, the side brush assembly 200 further includes a rotating shaft 220 arranged longitudinally relative to the ground, a brush head 240 connected to the bottom end of the rotating shaft 220, and a driven wheel 230 provided on the rotating shaft 220, the driven wheel 230 cooperates with the driving wheel 250 of the driving assembly arranged in the main housing.

[0040] Specifically, as shown in the accompanying drawings Figure 2 The rotating shaft 220 of the side brush assembly 200 is usually arranged perpendicular to the ground, the part of the bottom end of the rotating shaft 220 extending out of the main housing is provided with the brush head 240 contacting the ground, and the rotating shaft 220 cooperates with the driving wheel 250 of the driving assembly in the main housing through the driven wheel 230. Similarly, the driven wheel 230 can also be any one of a gear, a sprocket, a friction wheel, and a belt wheel, or a composite wheel composed of multiple wheels.

[0041] Preferably, the driven wheel 230 is sleeved at the bottom end of the rotating shaft 220, and the driven wheel 230 has an assembly part extending outward from the center thereof, and the brush head 240 is sleeved on the assembly part.

[0042] Specifically, as shown in the drawings, Figure 2 the end surface of the driven wheel 230 has a groove for accommodating the rotating shaft 220, and the driven wheel 230 is partially sleeved on the rotating shaft 220 through the groove, and then the brush head 240 is sleeved on the assembly part extending outward from the center of the other end surface of the driven wheel 230 opposite to the end surface where the groove is located. In this way, the positioning structures in the axial direction are sequentially formed, and the installation is facilitated. Specifically, the positioning of the driven wheel 230 and the rotating shaft 220 in the axial direction is realized through the groove, so that the shaft neck or the limiting structure does not need to be processed on the rotating shaft 220, and the rotating shaft 220 can directly adopt a column with a constant diameter. For the driven wheel 230, it itself needs to be processed to a certain extent, so that the assembly part can be formed on the end surface thereof, and the groove that can cooperate with the assembly part is also processed on the end surface of the brush head 240, and then the positioning in the axial direction is formed.

[0043] Overall, such a structure design mainly sequentially forms two axial positioning structures in the axial direction, and facilitates the installation from the inside to the outside. Meanwhile, the above axial positioning structures can all be placed on the driven wheel 230 or the brush head 240, and the corresponding positioning structures are formed, which mainly considers that the rotating shaft 220 needs to ensure the stability of rotation, and generally needs to adopt a rigid metal material, while the transmission structure in the dust collection head does not have a too precise requirement, so that the driven wheel 230 and the brush head 240 can both adopt injection molded parts, and the structure is constructed on the injection molded parts, which is more convenient compared with the metal parts.

[0044] In one embodiment, the center of the brush head 240 has a first assembly hole, the center of the driven wheel 230 has a second assembly hole, and the bottom end of the rotating shaft 220 has an assembly blind hole, and the brush head 240, the driven wheel 230 and the rotating shaft 220 are connected into one body through a threaded connecting piece 241 sequentially penetrating the first assembly hole, the second assembly hole and the assembly blind hole.

[0045] Specifically, as shown in the drawings, Figure 2 on the basis of the two axial positioning structures of the brush head 240, the driven wheel 230 and the rotating shaft 220, the threaded connecting piece 241 for axial assembly can directly connect the three into one body, and the assembly and disassembly are very convenient.

[0046] In one embodiment, the side brush assembly 200 further comprises a side brush housing 210 connected to the end of the main housing, and the side brush housing 210 is provided with a fixing frame 211, and the rotating shaft 220 and the driven wheel 230 are both fixed on the fixing frame 211.

[0047] Specifically, as shown in the drawings Figure 2 The side brush assembly 200 has a side brush housing 210 mounted on the side of the main housing, which forms a space with the main housing for mounting various components of the side brush assembly 200. In this space, a fixing frame 211 is provided, the upper end of the rotating shaft 220 is mounted on the upper end of the fixing frame 211 through a rotating shaft sleeve 221, and the lower end of the driven wheel 230 is mounted on the lower end of the fixing frame 211 through a bearing 231, thereby achieving the mounting of the rotating shaft 220, the driven wheel 230, and the brush head 240 in the side brush housing 210.

[0048] In addition, the side brush housing 210 has an open side, and the opening edge can be buckled on the side of the main housing, thereby achieving the mounting of the side brush housing 210 on the side of the main housing. The side brush housing 210 can be connected to the main housing through a threaded member, thereby achieving detachability. When the user does not need to use the side brush, the entire side brush assembly 200 can be detached.

[0049] In one embodiment, the driving wheel 250 has a bevel gear portion at one axial end for cooperating with the side brush assembly 200, and a transmission joint 260 at the other end for clamping the end of the roller of the roller brush assembly 100. The middle part between the two ends of the driving wheel 250 is transmissionally connected to the driving motor of the driving assembly through a transmission member 270.

[0050] Specifically, as shown in the drawings Figure 2 The driving wheel 250 is arranged between the side brush assembly 200 and the roller brush assembly 100. The bevel gear portion at one end of the driving wheel 250 cooperates with the bevel gear portion of the driven wheel, thereby achieving transmission and changing the direction of the output rotation. The other end of the driving wheel 250 has a wheel shaft coaxial with the roller of the roller brush assembly 100, and the transmission joint 260 is mounted on the wheel shaft. The end surface of the transmission joint 260 is not a flat surface, but has a protruding structure for clamping. The protruding structure can be clamped and cooperated with the corresponding recess on the end cover 110 of the roller of the roller brush assembly 100. In this embodiment, as shown in the drawings Figure 2 The transmission member 270 on the driving wheel 250 adopts a transmission belt.

[0051] In one embodiment, the main housing is provided with a mounting cavity for mounting the roller brush assembly 100. One end of the roller of the roller brush assembly 100 can be clamped with the transmission joint 260 arranged on one side wall of the mounting cavity, and the other end of the roller can be detachably connected to the other side wall of the mounting cavity through a connecting mechanism.

[0052] Specifically, as shown in the drawings Figure 1 and Figure 2As shown, the assembly cavity is actually the cavity where the suction port of the suction head is located, and the transmission joint 260 of the driving assembly in the main shell is arranged on the cavity wall of one side of the assembly cavity. During assembly, first, one end of the roller brush assembly 100 is connected with the transmission joint 260, and then the other end is fixedly connected with the cavity wall of the other side of the assembly cavity through the connecting mechanism.

[0053] In one embodiment, the connecting mechanism includes a first connecting piece 120 arranged at the end of the roller and a second connecting piece 280 arranged in a limiting sliding groove 209 arranged on the cavity wall of the assembly cavity, and a resilient piece matched with the second connecting piece 280 is also arranged in the limiting sliding groove 209, and a limiting clamping groove is arranged on the first connecting piece 120.

[0054] Wherein, when the roller brush assembly 100 is assembled into the assembly cavity along the radial direction of the roller, the second connecting piece 280 is extruded by the first connecting piece 120 and moves into the limiting sliding groove 209 and extrudes the resilient piece; when the second connecting piece 280 corresponds to the limiting clamping groove of the first connecting piece 120, it is partially extruded from the limiting sliding groove 209 under the pushing of the resilient piece and clamped into the limiting clamping groove.

[0055] Specifically, as shown in the accompanying drawings Figure 3 And Figure 4 As shown, the cavity wall of the assembly cavity is first provided with an assembly groove for the first connecting piece 120 to enter, and the assembly groove is a longitudinally extending structure, and the bottom of the assembly groove is open, and the first connecting piece 120 can enter the assembly groove through the opening. The cavity wall of the assembly cavity is also provided with a transversely extending limiting sliding groove 209, and the limiting sliding groove 209 extends towards the direction close to the assembly groove and communicates with the assembly groove, and the second connecting piece 280 is arranged in the limiting sliding groove 209 and the end thereof can extend into the assembly groove. As shown in the accompanying drawings Figure 3 As shown, the side surface of the first connecting piece 120 is provided with a first limiting block 121 and a second limiting block 122, and the spacing area between the first limiting block 121 and the second limiting block 122 forms a limiting clamping groove, and the side surfaces of the first limiting block 121 and the second limiting block 122 as the two side walls of the limiting clamping groove are a first limiting surface 1212 and a second limiting surface 1221; the side surface of the first limiting block 121 corresponding to the second connecting piece 280 is a bevel as a first extrusion surface 1211, and the end surface of the second connecting piece 280 corresponding to the first limiting block 121 is a second extrusion surface 281.

[0056] When installing, the roller brush assembly 100 is installed into the assembly cavity along the radial direction of the roller, the first connecting piece 120 is inserted into the assembly groove through the opening, at this time, the second connecting piece 280 is inserted into the assembly groove due to the action of the elastic piece, so that the second extrusion surface 281 of the second connecting piece 280 is extruded with the first extrusion surface 1211 on the first connecting piece 120, so that the second connecting piece 280 is retracted into the limiting sliding groove 209 and the elastic piece is compressed. With the continuous deepening of the first connecting piece 120 into the assembly groove, the second connecting piece 280 is continuously extruded and moved, until the first connecting piece 120 moves to the limiting clamping groove corresponding to the second connecting piece 280, at this time, the second connecting piece 280 is inserted into the limiting clamping groove under the action of the elastic piece, thereby completing the assembly.

[0057] In addition, as shown in the drawings Figure 3 When the second connecting piece 280 corresponds in the limiting clamping groove, the surface corresponding to the first limiting surface 1212 above the second connecting piece 280 needs to be set as a slope, specifically a slope towards the opening of the assembly groove, so that when disassembling, the roller brush assembly 100 can be directly pulled down, and the first limiting surface 1212 can extrude the slope above the second connecting piece 280 to press the second connecting piece 280 into the limiting sliding groove 209 again.

[0058] Through the design of the above structure, the roller brush assembly 100 only needs to be installed and disassembled by being pulled up and pulled down, without the need for other operations and connecting parts, and the assembly and disassembly are convenient.

[0059] Preferably, a sliding opening communicating with the limiting sliding groove 209 is formed in the groove wall corresponding to the limiting sliding groove 209 on the main shell, and the second connecting piece 280 has a sliding operation part extending into the sliding opening. Referring to the drawings Figure 4 The sliding operation part is exposed on the side surface of the main shell through the sliding opening, so that the user can directly move the second connecting piece 280 through the sliding operation part when assembling and disassembling the roller brush assembly 100, and the roller brush assembly 100 can be installed more quickly. At the same time, the sliding operation part also serves as an indication of the assembly state and position of the second connecting piece 280, and can intuitively show the position of the second connecting piece 280, so as to reflect the installation state of the roller brush assembly 100, whether the roller brush assembly 100 is installed in place, and other information.

[0060] The embodiment of the application also provides a dust collector, which comprises the dust collecting head and a dust collecting main machine 500 connected with the dust collecting head through the dust collecting pipe 300.

[0061] In one embodiment, the main machine shell 510 of the dust collecting main machine 500 extends a connecting part at the front end, and the dust cup 400 of the dust collector is detachably installed at the connecting part through a clamping mechanism, the clamping mechanism comprising a clamping groove 511 formed in the side surface of the connecting part, a clamping hook 411 arranged on the outer wall of the dust cup 400, and a movable buckle 420 arranged at the clamping hook 411.

[0062] Among them, the snap hook 411 can extend into the snap groove 511 and be hooked at the edge of the snap groove 511. One end of the movable snap hook 420 is hinged to the dust cup 400, and the other end has an elastic protrusion 423 that can cooperate with the fixed snap groove on the connecting part.

[0063] Specifically, as shown in the accompanying drawings Figure 5 and Figure 6 As shown, a connecting portion extends from the front end of the main housing 510, and the connecting portion is used to install the dust cup 400. In the installed state, the outer wall of the dust cup 400 is in contact with the side of the connecting portion. A detachable snap-in mechanism is provided between the dust cup 400 and the connecting portion. The snap-in mechanism includes two parts. The first part is a snap-in groove 511 and a snap-in hook 411. The snap-in hook 411 is formed on the outer wall of the dust cup housing 410. It can be directly inserted into the snap-in groove 511 and hooked on the edge of the snap-in groove 511. It plays the main connecting role. The other part is a movable snap-in 420 for keeping the snap-in groove 511 matched with the snap-in hook 411 to realize the auxiliary function of connection.

[0064] The movable buckle 420 is arranged in the buckle mounting groove 412 at the front end of the dust cup housing 410. The hinge portion 422 at the rear end of the movable buckle 420 is installed in the hinge hole 413 near the bottom position of the buckle mounting groove 412. The movable buckle 420 can rotate within a certain angle range with the hinge portion 422 as the rotation center. The angle range is limited by the slot width of the buckle mounting groove 412. The front end of the movable buckle 420 extends out of the buckle mounting groove 412 and is formed with a spring seat 421. The spring seat 421 is used to cooperate with one end of the spring 430. The other end of the spring 430 abuts against an abutment extending from a side edge of the slot of the buckle mounting groove 412. The abutment is supported by a limiter 414 extending from the front inner wall of the dust cup housing 410 where the dust cup cover 415 is located. The front end of the movable buckle 420 has an elastic protrusion 423 above the spring seat 421. The elastic protrusion 423 can be inserted into or removed from the fixed slot adjacent to the engaging slot 511 provided on the connecting portion as the movable buckle 420 rotates. The cooperation between the spring 430 and the spring seat 421 uses elastic force to limit the rotation of the movable buckle 420 in the absence of external force, thereby keeping the elastic protrusion 423 engaged in the fixed slot, thereby keeping the engaging slot 511 and the engaging hook 411 engaged with each other, and maintaining the installation state of the dust cup 400. Through the limited installation of the main connecting structure and the auxiliary connecting structure, the installation structure of the dust cup 400 is double protected.

[0065] When the dust cup 400 needs to be disassembled, the user can rotate the movable buckle 420 through the disassembly protrusion 424 on the movable buckle 420, overcome the elastic force of the spring 430, make the elastic protrusion 423 out of the fixed buckle slot, and then make the clamping slot 511 and the clamping hook 411 separate from each other, so that the dust cup 400 can be disassembled, which is very convenient.

[0066] In addition, as shown in the drawings Figure 5 The top of the dust cup shell 410 is matched with the position of the connecting portion, one side is provided with the structure of the movable buckle 420, and the other side is provided with the torsion spring sleeve 440 and the torsion spring 450 for mounting the dust cup cover 415.

[0067] In one embodiment, a connector 520 for connecting the dust collection pipe 300 is embedded in the front end of the connecting portion, a lighting lamp 530 is mounted in the gap between the outer wall of the connector 520 and the inner wall of the part of the main machine shell 510 corresponding to the front end of the connecting portion, and the outer wall of the connector 520 and the inner wall of the main machine shell 510 are respectively provided with lamp mounting grooves for fixing the lighting lamp 530.

[0068] Specifically, as shown in the drawings Figure 5 And Figure 6 The front end of the connecting portion of the main machine shell 510, i.e., the connector 520 embedded in the frontmost end of the dust collection main machine 500, is used to connect the dust collection pipe 300. On the basis of the structure of the connector 520, a lighting lamp 530 is further arranged on the dust collection main machine 500, the lighting lamp 530 is composed of a light guide column 531 and a light source 532, and is embedded in the gap between the connector 520 and the main machine shell 510. The outer wall of the connector 520 and the inner wall of the main machine shell 510 are respectively formed with a second lamp mounting groove 521 and a first lamp mounting groove 512, so that the lighting lamp 530 is limitingly mounted in each direction.
