[0025] Reference Figures 1 to 3The embodiment of the utility model provides a floor cleaner, comprising a walking device 2 and a cleaning unit 1 movably connected to the walking device 2. The walking device 2 can drive the cleaning unit 1 to clean the floor when walking on the floor, for example, it can be used to mop, sweep or vacuum the floor. When the cleaning unit 1 mops the floor, the cleaning unit 1 includes a mop for mopping the floor. When the cleaning unit 1 sweeps the floor, the cleaning unit 1 includes a sweeping brush for sweeping the floor. When the cleaning unit 1 vacuums the floor, the cleaning unit 1 includes a dust suction member for absorbing dust. The walking device 2 is provided with a collision detection switch 3, and the collision detection switch 3 is connected to a control unit (not shown in the figure). The control unit is connected to a reaction unit 4. The cleaning unit 1 is provided with a trigger member 5. The cleaning unit 1 can move in the opposite direction relative to the walking device 2 when colliding with an external object, thereby driving the trigger member 5 to trigger the collision detection switch 3. The collision detection switch 3 can be triggered to send a signal to the control unit so that the control unit controls the reaction unit 4 to react.

[0026] The floor cleaner provided by the embodiment of the utility model has a collision detection switch 3 on the walking device 2, the collision detection switch 3 is connected to a control unit, the control unit is connected to a reaction unit 4, and a trigger member 5 is provided on the cleaning unit 1. The cleaning unit 1 can move in the opposite direction relative to the walking device 2 when colliding with an external object, thereby driving the trigger member 5 to trigger the collision detection switch 3. The collision detection switch 3 can send a signal to the control unit when triggered, so that the control unit controls the reaction unit 4 to react. That is, the floor cleaner provided by the embodiment of the utility model can detect the collision through the collision detection switch 3 when colliding with an external object, and react through the reaction unit 4, so the degree of automation is high, thereby improving the user experience.

[0027] The walking device 2 can be separated from the cleaning unit 1 and used as an independent toy for children or pets to play with. In order to prevent the collision detection switch 3 from affecting the feel and appearance of the side of the walking device 2, the collision detection switch 3 is preferably arranged on the bottom surface of the walking device 2 in this embodiment. Compared with arranging the collision detection switch 3 on the side of the walking device 2, the collision detection switch 3 is arranged on the bottom surface of the walking device 2 in this embodiment, which can avoid the problem that the collision detection switch 3 affects the feel and appearance of the side of the walking device 2.

[0028] The cleaning unit 1 has a accommodating chamber A, and the walking device 2 is movably arranged in the accommodating chamber A, that is, the cleaning unit 1 is sleeved on the outside of the walking device 2, thereby realizing the movable connection between the cleaning unit 1 and the walking device 2. Compared with the method of realizing the movable connection between the cleaning unit 1 and the walking device 2 through other movable connection structures, the structure of this embodiment is simpler.

[0029] Specifically, refer to Figures 1 to 3The cleaning unit 1 includes a cover shell 11 and a cleaning member 12 arranged outside the cover shell 11. The inner cavity of the cover shell 11 is a accommodating cavity A. An opening B is arranged at the bottom of the cover shell 11. The walking device 2 walks on the ground through the opening B. When the walking device 2 walks on the ground, it can drive the cleaning member 12 to clean the ground through the cover shell 11. The trigger member 5 is arranged in the opening B.

[0030] In order to clean the floor more thoroughly, the cover shell 11 can rotate around the center of the opening B to drive the cleaning member 12 to rotate and clean the floor. In this way, the cleaning member 12 can not only move to clean the floor, but also rotate to clean the floor, thereby cleaning the floor more thoroughly.

[0031] In order to realize the rotation of the cover shell 11 around the center of the opening B, a driving unit (not shown in the figure) is provided on the walking device 2 in this embodiment, and the cover shell 11 is connected to the driving unit, and the driving unit is used to drive the cover shell 11 to rotate around the center of the opening B.

[0032] On the basis of the above embodiment, the trigger member 5 is arranged around the opening B in this embodiment, so that it can be ensured that the trigger member 5 can trigger the collision detection switch 3 when the cover shell 11 rotates to any position and collides with an external object.

[0033] Reference Figure 3 An elastic member 6 is provided between the cleaning unit 1 and the traveling device 2. The reverse movement of the cleaning unit 1 relative to the traveling device 2 can cause the elastic member 6 to undergo elastic deformation. The elastic deformation recovery of the elastic member 6 can drive the cleaning unit 1 to reset. The setting of the elastic member 6 can enable the cleaning unit 1 and the traveling device 2 to quickly reset after a collision.

[0034] The elastic member 6 is preferably multiple and evenly distributed along the circumference of the walking device 2. Compared with the embodiment with only one elastic member 6, the multiple elastic members 6 in this embodiment can all play a role in restoring when a collision occurs, and the restoring speed is faster. Specifically, the elastic member 6 includes a spring 61 and a top block 62.

[0035] The reaction unit 4 is at least one of the running wheels and the alarm member of the running device 2. Figure 2 When the walking wheel is shown, the control unit controls the walking wheel to turn or stop after receiving the signal. When the reaction unit 4 is an alarm component, the control unit controls the alarm component to alarm after receiving the signal. The alarm component here can be an alarm component such as an LED that alarms through light, or an alarm component such as a buzzer that alarms through sound.

[0036] There are two collision detection switches 3, which are respectively arranged on both sides of the front end of the cleaning unit 1, and the angle between the two collision detection switches 3 is 60 to 70 degrees. Of course, there can also be only one collision detection switch 3, which is arranged on the front side of the cleaning unit 1. Compared with the embodiment with only one collision detection switch 3, the detection range of this embodiment is wider, and collision with foreign objects can be detected regardless of the front side, left side, or right side.

[0037] The collision detection switch 3 can be a photoelectric switch, an infrared switch, or a mechanical switch as shown in the figure. When it is a mechanical switch, when the cleaning unit 1 collides with a foreign object, it moves in the opposite direction relative to the walking device 2, thereby driving the trigger member 5 to push the push rod 31 of the mechanical switch to move in the slide groove 32, thereby triggering the mechanical switch. When the mechanical switch is triggered, it can send a signal to the control unit so that the control unit controls the reaction unit 4 to respond.

[0038] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
