That is, when the dust box 140 is placed in the box storage space 116, the first sensing unit 150 can know that the dust box 140 is placed in the box storage space 116 by the first identifying unit 144. When the first sensing unit 150 senses the first identifying unit 144, the first sensing unit 150 transmits the information to a controller (not shown) on the circuit board 130. When the sweeper 100 is activated, the circuit board 130 is activated. The roller brush 160 and the side brush 165 assist in performing the cleaning operation. On the contrary, when the first sensing unit 150 does not sense the first identifying unit 144, the circuit board 130 does not activate the roller brush 160 and the side brush 165.

Similarly, when the air filter box 170 is placed in the box storage space 116, the second sensing unit 180 can know that the air filter box 170 is placed in the box storage space 116 by the second identification unit 174, and this is Information is passed to the controller on board 130. Since the walking route of the sweeper 100 when performing the air filtering operation may be the same as or different from the walking route when performing the cleaning operation, the controller may select the walking path of the sweeping machine 100 according to the received result. Further, when the sweeper 100 performs the air filtering operation, the roller brush 160 and the side brush 165 are not activated, and power can be saved.

In the embodiment, the first identifying unit 144 and the second identifying unit 174 are respectively two touch bumps, and the first sensing unit 150 and the second sensing unit 180 are respectively two touch sensing switches. When the dust box 140 is placed in the box storage space 116, the first identification unit 144 will push to the first sensing unit 150 with a change in pressure. Similarly, when the air filter box 170 is placed in the box storage space 116, the second identification unit 174 will push to the second sensing unit 180 with a change in pressure.

Of course, the types of the first sensing unit 144, the second identifying unit 174, the first sensing unit 150, and the second sensing unit 180 are not limited thereto, as long as the first sensing unit 150 and the second sensing unit 180 can respectively correspond to The first identification unit 144 and the second identification unit 174 are sensed, and it can be determined that the dust box 140 or the air filter box 170 is placed in the box storage space 116. In other embodiments, the first identifying unit 144 and the second identifying unit 174 may also be a magnet, an infrared emitter or a code, and the first sensing unit 150 and the second sensing unit 180 may also be a magnetic sensor. , an infrared sensor or a code reader.

The sweeper 100 can adjust the path of walking according to the sensing result of the space detecting sensor 190. In addition to avoiding the sweeper 100 colliding with other objects, when the second sensing unit 180 detects that the air filter box 170 is loaded into the box storage space 116, the program executed by the controller on the circuit board 130 can be automatically avoided. The sweeping machine 100 stays in a narrow space such as a bed or a cabinet or a table and chair corner, and moves to a relatively wide space (for example, a living room or other areas in the room) to reduce the sweeping machine 100 to stay in the air filter. The probability of a region with a lower net demand, which in turn increases the user's perception of the results of air filtration.

In addition, when the second sensing unit 180 detects that the air filter box 170 is loaded into the box storage space 116, the controller on the circuit board 130 activates the air quality sensor 192, and the air quality sensor 192 can be used to measure The amount of particulates in the air, the sweeper 100 is adapted to adjust the speed of travel or the rotational speed of the fan 120 based on the sensed results of the air quality sensor 192. For example, the sweeper 100 can select a fast moving away in a high air quality environment, a long stay in a low air quality environment, and the like. In addition, the controller on the circuit board 130 can also adjust the rotation speed of the fan 120 according to the result sensed by the air quality sensor 192, reduce the rotation speed of the fan 120 in a high air quality environment, and increase the fan 120 in a low air quality environment. Speed to achieve power management optimization.

In addition, the sweeping machine 100 is adapted to adjust the path of walking according to the sensing result of the human body infrared sensor 194. Since the human body infrared sensor 194 can sense the position of the person, the user can set the sweeper 100 to work close to or away from the human body. For example, when the sweeping machine 100 performs the cleaning operation, it can be set to work away from the vicinity of the human body to avoid collision with the user or to avoid noise generated by the operation affecting the user. When the sweeper 100 is to perform air filtration, it can be set to work close to the human body to provide better air quality for the user. Of course, the type of work to be set close to or away from the human body when the sweeper 100 performs the work is not limited to the above, and the user can adjust according to the demand, or the manufacturer can preset a specific one in advance. stroke.

In summary, the Sweeper of the present invention is provided with a first flow path and a second flow path. The first flow path and the second flow path respectively communicate with the storage space of the box body, and the storage space of the box body can be used for the dust box or the air. The filter box is placed. When the dust box is placed in the box storage space, the dust collecting opening is connected to the first flow path and is closed to the second flow path. When the dust collecting box is located in the box storage space and the fan is started, the air flow is from the position. The lower flow path enters the sweeping machine, and passes through the dust box and the fan and leaves the sweeper from the air outlet to perform the cleaning operation. When the air filter box is placed in the box storage space, the filter box opening communicates with the second flow path and is closed in the first flow path. When the air filter box is located in the box storage space and the fan is started, the air flow is from the upper position.
