However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.

Example one

The first embodiment of the present invention relates to a deodorization mechanism for a trash can, and as shown in fig. 1 and 8, the deodorization mechanism 1 is disposed opposite to the opening side 21 of the can body 2 of the trash can. Further, the deodorization mechanism 1 includes: deodorant clamp 11, drive arrangement 12 and host system.

The first movable rod 111 and the second movable rod 112 are opposite to each other along a first preset linear direction and are arranged in parallel; meanwhile, the third movable bar 113 and the fourth movable bar 114 are opposite to each other along the second preset linear direction and are arranged in parallel. The first preset linear direction is perpendicular to the second preset linear direction. Next, as shown in fig. 1, 2, 3 and 4, the driving device 12 is connected to the first movable bar 111 and the third movable bar 113, respectively, and as shown in fig. 2 and 3, the driving device 12 is used for driving the first movable bar 111 and the second movable bar 112 to move relative to each other along a first predetermined linear direction; meanwhile, the driving device 12 is further configured to drive the third movable bar 113 and the fourth movable bar 114 to move relative to each other along a second predetermined linear direction, so that the first movable bar 111, the second movable bar 112, the third movable bar 113 and the fourth movable bar 114 can enclose a clamping area 115 for opening or tightening the opening of the garbage bag. It should be noted that, in this embodiment, the first predetermined linear direction is perpendicular to the second predetermined linear direction, and in practical application, the first predetermined linear direction may not be perpendicular to the second predetermined linear direction, and an included angle formed between the first predetermined linear direction and the second predetermined linear direction may be any angle.

Finally, as shown in fig. 5, the main control module is further communicatively connected to the driving device 12, and the main control module is configured to receive a drum lid opening instruction or a drum lid closing instruction. After receiving the barrel cover closing instruction, the main control module can send a first driving signal to the driving device 12; and when the main control receives the barrel cover opening instruction, the main control can send a second driving signal to the driving device 12. In addition, in practical application, when the driving device 12 receives a first driving signal sent by the main control module, as shown in fig. 3, the first movable rod 111 and the second movable rod 112 can be driven to move toward a direction in which they are close to each other, and at the same time, the third movable rod 113 and the fourth movable rod 114 can be driven to move toward a direction in which they are close to each other, so that the clamping area 115 is continuously reduced, and the bag opening of the garbage bag 100 can be tightened. On the contrary, when the driving device receives the second driving signal sent by the main control module, as shown in fig. 2, the first movable rod 111 and the second movable rod 112 can be driven to move in the direction away from each other, and at the same time, the third movable rod 113 and the fourth movable rod 114 can be driven to move in the direction away from each other, so that the clamping area 115 is continuously enlarged, and the opening of the garbage bag 100 can be opened, so as to implement the garbage throwing by the user.

Specifically, in the present embodiment, as shown in fig. 4, the driving device 12 includes: a driving assembly 121 and a transmission assembly 122. The driving component 121 is in communication connection with the main control module, and the driving component 121 is configured to receive a first driving signal or a second driving signal. In addition, the transmission assembly 122 is connected to the driving assembly 121, and at the same time, the transmission assembly 122 is also connected to the first movable bar 111, the second movable bar 112, the third movable bar 113, and the fourth movable bar 114. In practical applications, as shown in fig. 2 and 3, the driving assembly 121 may drive the first movable bar 111 and the second movable bar 112 to move relative to each other along a first predetermined linear direction through the transmission assembly 122. Meanwhile, the driving assembly 121 drives the third movable rod 113 and the fourth movable rod to move relative to each other along a second predetermined linear direction through the transmission assembly 122.

Further, in the present embodiment, as shown in fig. 4, the driving unit 121 includes: motor 1211 and reducer 1212. And the transmission assembly 122 includes: a first master synchronizing wheel 1221, a first slave synchronizing wheel 1222, a first timing belt 1223, a second master synchronizing wheel 1224, a second slave synchronizing wheel 1225, and a second timing belt 1226. The motor 1211 is in communication connection with the main control module, so that the motor 1211 can receive the first driving signal or the second driving signal sent by the main control module. Next, as shown in fig. 2, 3 and 4, a first master synchronizing wheel 1221 is coaxially connected to an output shaft 12121 of the speed reducer 1212, and a first slave synchronizing wheel 1222 is disposed opposite to the first master synchronizing wheel 1221 in a first predetermined linear direction, and at the same time, a first synchronizing belt 1223 connects the first master synchronizing wheel 1221 and the first slave synchronizing wheel 1222. As shown in fig. 2, 3, and 4, the first timing belt 1223 further includes: a first inner transmission layer 12231 disposed toward the clamping region 115, and a first outer transmission layer 12232 disposed away from the clamping region 115. In addition, as shown in fig. 4, a second master synchronizing wheel 1224 is coaxially connected to an output shaft 12121 of the speed reducer 1212, and a second slave synchronizing wheel 1225 is disposed opposite to the second master synchronizing wheel 1224 in a second predetermined linear direction, and at the same time, a second timing belt 1226 connects the second master synchronizing wheel 1224 and the second slave synchronizing wheel 1225. As shown in fig. 2 and 3, the second timing belt 1226 further includes: a second inner transmission layer 12261 disposed toward the clamping region 115, and a second outer transmission layer 12262 disposed away from the clamping region 115.

Also, in order to satisfy the relative movement of the first and second

movable bars

111 and 112, as shown in fig. 2 and 3, the first movable bar 111 may be connected to the first outer transmission layer 12232 of the first synchronous belt 1223, and at the same time, the second movable bar 112 may be connected to the first inner transmission layer 12231 of the first synchronous belt 1223. Further, in order to achieve the relative movement of the third movable bar 113 and the fourth movable bar 114, the third movable bar 113 may be connected with the second outer transmission layer 12262 of the second timing belt 1226, and at the same time, the fourth movable bar 114 may be connected with the second inner transmission layer 12261 of the second timing belt. In practical applications, the motor 1211 can synchronously drive the first master synchronizing wheel 1221 and the second master synchronizing wheel 1224 to rotate through the speed reducer 1212, and at the same time, the first synchronizing belt 1223 and the second synchronizing belt 1226 can respectively drive the first slave synchronizing wheel 1222 and the second slave synchronizing wheel 1225 to rotate under the rotation motions of the first master synchronizing wheel 1221 and the second master synchronizing wheel 1224, so that the first movable rod 111 and the second movable rod 112 can perform a relative motion along a first preset linear direction, and at the same time, the third movable rod 113 and the fourth movable rod 114 can perform a relative motion along a second preset linear direction, so as to achieve the tightening and the opening of the bag opening of the garbage bag 100.

Further, in order to achieve the connection and fixation between the first movable bar 111 and the first timing belt 1223, in the present embodiment, as shown in fig. 6, a first notch 1111 and a first tooth row formed by a combination of a plurality of first teeth 1112 provided in the first notch 1111 may be provided at either end of the first movable bar 111, and the first teeth 1112 in the first tooth row may be sequentially provided in the first predetermined linear direction. In practical applications, as shown in fig. 6, the first tooth row in the first slot 1111 at either end of the first movable bar 111 can be engaged with the first outer transmission layer 12232 of the first synchronous belt 1223. It can be seen that, due to the engagement of the first teeth 1112 and the first outer transmission layer 12232 of the first synchronous belt 1223, the first movable bar 111 can be prevented from slipping when moving relative to the second movable bar 112, thereby improving the accuracy of the first movable bar 111 when moving relative to the second movable bar 112. Similarly, in order to achieve the connection and fixation between the second movable bar 112 and the first synchronous belt 1223, as shown in fig. 7, a second engaging groove 1121 and a second tooth row formed by combining a plurality of second teeth 1122 and provided in the second engaging groove 1121 may be provided at either end of the second movable bar 112, and the second teeth 1122 in the second tooth row may be sequentially provided along the first predetermined straight line direction. In practical applications, as shown in fig. 7, the second tooth rows of the second engaging grooves 1121 at either end of the second movable bar 112 can be engaged with the first inner transmission layer 12231 of the first synchronous belt 1223. It can be seen that, due to the engagement of the second teeth 1122 with the first inner transmission layer 12231 of the first timing belt 1223, the second movable bar 112 is prevented from slipping when moving relative to the first movable bar 111, thereby improving the accuracy of the movement of the second movable bar 112 and the first movable bar 111 relative to each other.

Likewise, in order to achieve the connection fixation between the third movable bar 113 and the second timing belt 1226, and the connection fixation between the fourth movable bar 114 and the second timing belt 1226. In this embodiment, the third movable bar 113 and the fourth movable bar 114 may respectively adopt the same structural design as the first movable bar 111 and the second movable bar 112, so that the third movable bar 113 and the second outer transmission layer 12262 of the second synchronous belt 1226 may be clamped and fixed, and meanwhile, the fourth movable bar 114 and the second inner transmission layer 12261 of the second synchronous belt 1226 may be clamped and fixed.

In addition, as a preferable mode, in order to improve the moving performance when the first movable bar 111 and the second movable bar 112 move relative to each other, as shown in fig. 2 and 3, in the present embodiment, the driving device 12 further includes: and a first guide rod 123, wherein the first guide rod 123 is arranged along the first preset linear direction, and the first guide rod 123 is further slidably connected with the first movable rod 111 and the second movable rod 112. It is thus apparent that the first and second

movable bars

111 and 112 can be guided by the first guide bar 123 while moving relative to each other, so that the moving performance of the first and second

movable bars

111 and 112 can be improved. However, in some embodiments, as shown in fig. 2 and 3, two first guide rods 123 are provided, and the two first guide rods 123 are opposite to each other along the second predetermined linear direction and are arranged in parallel, and meanwhile, two ends of the first movable rod 111 and two ends of the second movable rod 112 are slidably connected to the two first guide rods 123, respectively. As a result, the first and second

movable bars

111 and 112 are guided by the two first guide bars 123, and the movement performance when the first and second

movable bars

111 and 112 move relative to each other can be further improved.

Also, in order to improve the moving performance when the third movable bar 113 and the fourth movable bar 114 move relative to each other, as shown in fig. 2 and 3, in the present embodiment, the driving device 12 further includes: and a second guide bar 124, wherein the second guide bar 124 is arranged along a second predetermined linear direction, and the second guide bar 124 is further slidably connected to the third movable bar 113 and the fourth movable bar 114. It is thus apparent that the third and fourth

movable bars

113 and 114 can be guided by the second guide bar 124 while moving relative to each other, so that the moving performance of the third and fourth

movable bars

113 and 114 can be improved.
