DETAILED DESCRIPTION

[0039] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0040] First embodiment

[0041] See also Figures 1 to 3 This embodiment provides a cleaning brush driving mechanism 100, which has high driving stability and good cleaning effect, and can effectively clean the air duct 170 and the wind wheel 200.

[0042] The cleaning brush driving mechanism 100 provided in this embodiment includes a base 110, a cleaning brush roller 130 and a driving assembly 150. The base 110 is provided with an air duct 170. The air duct 170 includes a bottom wall 171 and side walls 173 arranged at both ends of the bottom wall 171. Driving accommodating grooves 190 are relatively opened on the two side walls 173. The driving accommodating grooves 190 are arranged along the extension direction of the joining line between the bottom wall 171 and the side walls 173. The driving assembly 150 is accommodated in the driving accommodating grooves 190. The two ends of the cleaning brush roller 130 respectively extend into the two opposite driving accommodating grooves 190 and are transmission-connected with the corresponding driving assembly 150. The driving assembly 150 is used to drive the cleaning brush roller 130 to move along the driving accommodating grooves 190.

[0043] In the present embodiment, a wind wheel 200 is provided in the air duct 170, and both ends of the wind wheel 200 are assembled on two side walls 173. At the same time, there is a gap in the air duct 170 between the wind wheel 200 and the bottom wall 171. During actual cleaning, the cleaning brush roller 130 moves in the gap in the air duct 170 to clean the bottom wall 171 of the air duct 170. At the same time, since the gap in the air duct 170 gradually narrows, when the cleaning brush roller 130 moves to the upper limit position, it can contact the wind wheel 200. At this time, the wind wheel 200 is slowly started to clean the wind wheel 200. The specific implementation principle can be referred to below.

[0044] It should be noted that the joining line between the bottom wall 171 and the side wall 173 in this embodiment refers to the connecting line between the two, that is, the edge line of the bottom wall 171. In this embodiment, the bottom wall 171 of the air duct 170 is an arc surface, and the joining line between the bottom wall 171 and the side wall 173 is also arc-shaped, so that the driving groove 190 is arc-shaped, and the cleaning brush roller 130 moves along the driving groove 190 and can be attached to the bottom wall 171 and move up and down along the width direction of the air duct 170 to clean the air duct 170.

[0045] The cleaning brush driving mechanism 100 provided by the present invention has a driving groove 190 opened on the side wall 173, and the driving component is accommodated in the driving groove 190. The end of the cleaning brush roller 130 extends into the driving groove 190 and is connected to the driving component 150 by transmission. The cleaning brush roller 130 moves along the driving groove 190 under the drive of the driving component 150. The driving stability of the cleaning brush roller 130 is high, and the cleaning brush roller 130 can move along the bottom wall 171 to achieve cleaning of the air duct 170.

[0046] See also Figures 4 to 7The driving assembly 150 includes a transmission belt 151, a transmission wheel group 153 and a transmission cover 155. The transmission wheel group 153 is rotatably arranged in the driving accommodating groove 190. The transmission belt 151 is arranged in the driving accommodating groove 190 and is wound around the transmission wheel group 153, and can rotate under the drive of the transmission wheel group 153. The end of the cleaning brush roller 130 extends into the transmission belt 151 and is connected to the transmission belt 151 for driving along the driving accommodating groove 190 under the drive of the transmission belt 151. The cleaning brush roller 130 is driven to move by the transmission wheel group 153 and the transmission belt 151, which further improves the stability of the movement of the cleaning brush roller 130 and has better transmission performance.

[0047] The drive accommodating groove 190 penetrates the side wall 173 and has an inner opening and an outer opening. The end of the cleaning brush roller 130 extends into the drive accommodating groove 190 from the inner opening. The transmission cover 155 is covered on the outer opening, and the transmission wheel group 153 is rotatably assembled on the transmission cover 155. By providing the transmission cover 155, the transmission belt 151 and the transmission wheel group 153 can be assembled first and then installed into the drive accommodating groove 190 during assembly, which is convenient for assembly. At the same time, the transmission cover 155 can be directly opened during disassembly and maintenance, which is very convenient.

[0048] In this embodiment, the transmission belt 151 is a belt, which is tightly wound around the transmission wheel set 153, and the transmission belt 151 is driven by the transmission wheel set 153 to circulate in the driving accommodating groove 190, thereby driving the cleaning brush roller 130 to move along the driving accommodating groove 190. In other preferred embodiments of the present invention, the transmission belt 151 can also be replaced by a transmission chain, which can also rotate under the drive of the transmission wheel set 153 and drive the cleaning brush roller 130 to move.

[0049] The transmission wheel group 153 includes a first driving member 153a, an active roller 153b and at least one driven roller 153c. The active roller 153b and the driven roller 153c are both rotatably arranged in the driving accommodating groove 190. The first driving member 153a is arranged on the base 110 and is connected to the active roller 153b in transmission. The transmission belt 151 is wound around the active roller 153b and the driven roller 153c, and rotates under the drive of the active roller 153b.

[0050] In this embodiment, the active roller 153b and the driven roller 153c are respectively arranged at the two ends of the driving groove 190, and the first driving member 153a is connected to the active roller 153b, driving the active roller 153b to rotate, and the active roller 153b drives the transmission belt 151 to move, and drives the cleaning brush roller 130 to move in the driving groove 190.

[0051] In this embodiment, the active roller 153b and the driven roller 153c are rotatably mounted on the transmission cover 155. During assembly, the transmission belt 151 is firstly wound around the active roller 153b and the driven roller 153c, and then the transmission cover 155 is covered on the external opening, so that the active roller 153b, the driven roller 153c and the transmission belt 151 can be accommodated in the driving accommodating groove 190, and then the end of the cleaning brush roller 130 is extended into the driving accommodating groove 190 to connect with the transmission belt 151. It should be noted that, since the driving accommodating groove 190 in this embodiment is arc-shaped, a certain margin needs to be left when the transmission belt 151 is wound around the active roller 153b and the driven roller 153c, so that the transmission belt 151 can fit with the inner wall of the driving accommodating groove 190 when it is installed in the driving accommodating groove 190, so that the transmission belt 151 can move along the inner wall of the driving accommodating groove 190.

[0052] The bottom wall 171 is also provided with a first gear rack 175, which is arranged along the extension direction of the joint line between the bottom wall 171 and the side wall 173. The cleaning brush roller 130 is also provided with a first gear 131, which is meshed with the first gear rack 175. The cleaning brush roller 130 can rotate under the drive of the transmission belt 151 and move along the extension direction of the first gear rack 175. By arranging the first gear rack 175 on the bottom wall 171 and the first gear rack 175 being arranged along the edge of the bottom wall 171, the cleaning brush roller 130 is meshed with the first gear rack 175 through the first gear 131, so that the cleaning brush roller 130 rotates under the drive of the transmission member and moves along the extension direction of the first gear rack 175, that is, the cleaning brush roller 130 can realize self-rotation while moving along the bottom wall 171, so as to prevent dust from accumulating on one side of the cleaning brush roller 130, and further improve the cleaning effect of the cleaning brush roller 130.

[0053] It should be noted that in the present embodiment, there are two first gear racks 175, and the two first gear racks 175 are respectively opened on the two side edges of the bottom wall 171, so that the first gear teeth are arranged close to the end of the cleaning brush roller 130. With the cooperation of the first gear racks 175 on both sides, the cleaning brush roller 130 can realize self-rotation and movement along the bottom wall 171, thereby improving the cleaning effect.

[0054] In other preferred embodiments of the present invention, the first gear rack 175 can also be set in the middle of the bottom wall 171, along the surface of the bottom wall 171 and along the width direction of the air duct 170, which can also realize the solution of the cleaning brush roller 130 rotating while moving along the bottom wall 171.

[0055] A transmission structure is disposed on the transmission belt 151 , and the transmission structure is in transmission connection with the end of the cleaning brush roller 130 , so as to drive the cleaning brush roller 130 to rotate or move along the driving accommodating groove 190 .

[0056] In this embodiment, the transmission structure includes a second gear rack 157, which is arranged on the inner side of the transmission belt 151. The end of the cleaning brush roller 130 extending into the transmission belt 151 is also provided with a second gear 133, which meshes with the second gear rack 157, so that the transmission belt 151 can drive the cleaning brush roller 130 to rotate. The cleaning brush roller 130 is driven to rotate by the gear rack structure, and the first gear 131 is meshed on the first gear rack 175, and the first gear 131 is meshed on the first gear rack 175. The first gear rack 175 can be rotated to move along the first gear rack 175, that is, the cleaning brush roller 130 can be driven to move along the driving accommodating groove 190, so that the cleaning brush roller 130 can rotate while moving along the bottom wall 171, thereby improving the cleaning effect. At the same time, the gear rack structure also ensures the stability of force transmission and avoids slipping.

[0057] In this embodiment, the second gear rack 157 is evenly distributed on the inner surface of the transmission belt 151 and meshes with the upper and lower sides of the second gear 133. When the transmission belt 151 moves, it can drive the second gear 133 to rotate, thereby driving the cleaning brush roller 130 to rotate. Under the meshing action of the first gear rack 175, the cleaning brush roller 130 can move along the first gear rack 175, thereby realizing a solution of rotating while moving along the bottom wall 171.

[0058] The cleaning brush driving mechanism 100 provided in the present embodiment has the following cleaning scheme: starting the first driving member 153a to drive the transmission belt 151 to move forward, thereby driving the cleaning brush roller 130 to rotate; under the meshing action of the first gear rack 175, the cleaning brush roller 130 moves upward along the first gear rack 175 while rotating, thereby being able to move along the bottom wall 171 to clean the bottom wall 171 of the air duct 170; when the first gear 131 moves to the upper limit position of the first gear rack 175, that is, when the cleaning brush roller 130 moves to the upper limit position of the driving accommodating groove 190, the first driving member 153a is stopped; here, since the gap of the air duct 170 is narrowed, the cleaning brush roller 130 can be abutted against the wind wheel 200; at this time, the wind wheel 200 is slowly started to clean the wind wheel 200. After cleaning is completed, the first driving member 153a is started in reverse again, driving the transmission belt 151 to move in the reverse direction, thereby driving the cleaning brush roller 130 to rotate in the reverse direction. Under the meshing action of the first wheel rack 175, the cleaning brush roller 130 moves downward along the first wheel rack 175 while rotating, so that it can move along the bottom wall 171, and the bottom wall 171 of the air duct 170 is cleaned again.

[0059] See also Figure 8 and Fig. 9A brush roller accommodating groove 177 for accommodating the cleaning brush roller 130 is also provided on the bottom wall 171. The extension direction of the brush roller accommodating groove 177 is parallel to the extension direction of the cleaning brush roller 130, and the two ends of the brush roller accommodating groove 177 extend to the two side walls 173 respectively. An avoidance groove 191 connected to the driving accommodating groove 190 is also provided on the side wall 173. The avoidance groove 191 corresponds to the brush roller accommodating groove 177. The driving assembly 150 is also used to drive the cleaning brush roller 130 to move along the avoidance groove 191 so that the cleaning brush roller 130 enters or leaves the brush roller accommodating groove 177. By opening a brush roller accommodating groove 177 on the bottom wall 171 and an avoidance groove 191 on the side wall 173, the driving assembly 150 drives the cleaning brush roller 130 to move along the avoidance groove 191, so that it can enter or leave the brush roller accommodating groove 177. By opening the brush roller accommodating groove 177, the cleaning brush roller 130 can be accommodated by the brush roller accommodating groove 177 when cleaning is not needed, thereby preventing the cleaning brush roller 130 from protruding above the bottom wall 171 to obstruct the airflow in the air duct 170, and also preventing the cleaning brush roller 130 from affecting the movement of the wind wheel 200 in the air duct 170.

[0060] In this embodiment, the transmission belt 151 is accommodated in the driving accommodating groove 190 and the avoidance groove 191, and there are two driven rollers 153c, one of which is arranged at the bottom of the avoidance groove 191, and the other driven roller 153c is arranged at the connection between the driving accommodating groove 190 and the avoidance groove 191, so that the transmission belt 151 can be distributed in the driving accommodating groove 190 and the avoidance groove 191 at the same time.

[0061] In this embodiment, the brush roller accommodating groove 177 is arranged along the length direction of the air duct 170 and is in a straight strip shape, and can accommodate the cleaning brush roller 130 in a non-cleaning state. In addition, in this embodiment, the first gear rack 175 extends into the brush roller accommodating groove 177, so as to assist in driving the cleaning brush roller 130 to enter or leave the brush roller accommodating groove 177.

[0062] In this embodiment, a baffle 179 is provided on the brush roller receiving groove 177, and the brush roller receiving groove 177 has an upper side edge and a lower side edge opposite to each other, and the baffle 179 is hinged on the lower side edge, so that the cleaning brush roller 130 enters or leaves the brush roller receiving groove 177 along the upper side edge under the drive of the driving assembly 150. By providing the baffle 179, and the baffle 179 is rotatably hinged on the lower side edge of the brush roller receiving groove 177, the brush roller receiving groove 177 can be rotated to open or close, thereby ensuring the integrity of the air duct 170 and preventing the occurrence of local eddies near the brush roller receiving groove 177 to affect the air outlet of the air duct 170.

[0063] In this embodiment, the upper edge of the brush roller accommodating groove 177 has a rounded structure, which facilitates the cleaning brush roller 130 to enter or slide out of the brush roller accommodating groove 177 .

[0064] In this embodiment, the base 110 is further provided with a second driving member 179a (not shown), which is in transmission connection with the baffle 179 and is used to drive the baffle 179 to rotate relative to the lower edge of the brush roller receiving groove 177 to open or close the brush roller receiving groove 177. Specifically, the second driving member 179a is a stepping motor, which is arranged outside the side wall 173 of the base 110, and can drive the baffle 179 to rotate, thereby opening or closing the brush roller receiving groove 177.

[0065] It should be noted that, in this embodiment, the first driving member 153 a and the second driving member 179 a are started simultaneously, and the cleaning brush roller 130 is driven to enter or leave the brush roller accommodating groove 177 while the baffle 179 is opened.

[0066] In summary, the present embodiment provides a cleaning brush driving mechanism 100, and its movement process is as follows: after the self-cleaning function is turned on, the first driving member 153a and the second driving member 179a are started at the same time, the second driving member 179a drives the baffle 179 to rotate and opens the brush roller accommodating groove 177, the first driving member 153a drives the transmission belt 151 to move forward, thereby driving the cleaning brush roller 130 to move through the second wheel rack 157, thereby driving the cleaning brush roller 130 to leave the brush roller accommodating groove 177, and the cleaning brush roller 130 is moved to the first wheel rack 175 and the cleaning brush roller 130. Under the meshing action of the first gear 131 on the roller 130, the cleaning brush roller 130 moves upward along the first gear rack 175 along the air duct 170 while rotating, so that it can move along the bottom wall 171 to clean the bottom wall 171 of the air duct 170; when the cleaning brush roller 130 moves to the top of the driving accommodating groove 190, the first driving member 153a stops. At this time, the cleaning brush roller 130 can be supported on the wind wheel 200 after the gap of the air duct 170 is narrowed. At this time, the wind wheel 200 is slowly started to clean the wind wheel 200.
