Self-moving ground treatment device

Technical field

The invention relates to a self-moving ground processing device, belonging to the technical field of daily small household appliance manufacturing.

Background technique

The automatic wiping structure of the smart vacuum cleaner currently used on the market is to fix the rag directly on the bottom of the machine, or to stick the rag on the bottom surface of the water tank, and then fix the water tank to the bottom of the machine to achieve the purpose of cleaning the ground with water. However, when the water tank is used together with the rag, since the rag is completely wetted (the water in the water tank gradually penetrates into the rag), the friction coefficient between the rag and the ground increases, and the weight of part of the body acts on the rag, causing the machine and the ground. The frictional resistance between the two is too large, causing the machine to slip on the ground with water, which can not achieve effective cleaning, thus seriously affecting the working efficiency of the smart vacuum cleaner. In addition, when the smart vacuum cleaner climbs the slope, the end of the water tank away from the driving wheel is easy to stand against the ground, so that the robot cannot walk.

A self-moving ground treatment device includes a body base and a water tank, and a rag is attached to the bottom of the water tank, and the water tank is floatingly connected to the bottom surface of the base of the body.

Specifically, the floating gap between the top surface of the water tank and the bottom surface of the body base is 0.5-10 mm.

In the working state, the rag is pressed against the ground by the gravity of the water tank and the rag itself.

More specifically, the body base or the water tank is provided with a guide post, and the water tank or the base of the body is correspondingly provided with a guide hole, and the guide hole is sleeved on the guide post and moves up and down in the direction of the guide post. In order to facilitate positioning, the contact faces of the guide post and the guide hole are correspondingly provided with ridges and grooves.

In addition, an elastic member is disposed between the base of the body and the water tank, and two ends of the elastic member are respectively positioned on the base of the body and the water tank. The elastic member is a spring piece or a spring.

In order to reduce the number of cleaning and replacement of the rag, the rag is also covered with a disposable rag that covers the periphery of the water tank and the edge is flipped over the inside of the water tank.

In summary, the present invention provides a self-moving ground treatment device. After the rag is attached to the bottom surface of the water tank, the water tank and the base of the body are floated and installed, so that a certain gap is left between the two, the water tank and The rag can float up and down within a certain space. For the rag, the force actually acting on the ground is only the gravity of the water tank and the rag itself, and does not include the gravity of the machine itself, so the friction between the rag and the ground is compared with the ordinary product. It will reduce the slippage of the machine on the ground with water, improve the cleaning efficiency of the floor, and improve the obstacle-proof ability of the machine with water tank.

detailed description

Embodiment 1

1 is a schematic structural view of a self-moving ground processing apparatus according to an embodiment of the present invention; FIG. 2 is a cross-sectional view of a self-moving ground processing apparatus according to an embodiment of the present invention; and FIG. 3 is an exploded view of a self-moving ground processing apparatus according to an embodiment of the present invention; . As shown in FIG. 1 to FIG. 3, the present invention provides a self-moving ground treatment device A, which includes a body base 100 and a water tank 200. A rag 210 is attached to the bottom of the water tank 200, and the water tank 200 is floatingly connected to the body. On the bottom surface of the base 100. In order to ensure that the water tank 200 can float to a certain extent with respect to the body base 100, and to ensure that the floating does not constitute an obstacle to the walking of the self-moving ground treatment device, the size of the floating gap should have certain requirements, usually under normal circumstances. The floating gap may be 0.5-10 mm. The water tank 200 floats up and down with respect to the body base 100, and can be realized by different physical structures. For example, the base of the body or the water tank is provided with a guide post, and the water tank or the base of the body is correspondingly provided with a guide hole, and the guide hole is sleeved on the guide post and moves up and down in the direction of the guide post. As shown in FIG. 3, in the present embodiment, the guide post 201 disposed on the water tank 200 is used to cooperate with the guide hole 111 (shown in FIG. 1) corresponding to the base 10 of the body. For effective positioning, the contact surface of the guide post and the guide hole may be further provided with a rib 202 and a groove (not shown) for positioning. In addition, in order to reduce the number of cleaning and replacement of the rag 210, the rag 210 is further covered with a disposable rag 220, and the specific structure is to cover the periphery of the water tank 200 with the disposable rag 220, the edge of the disposable rag 220. The flip is fixed inside the water tank 200. In order to be able to effectively position and replace easily, the edge of the disposable rag 220 can be used with rubber bands or elastic bands, or through corresponding settings. This is achieved by a nylon gluing on the edge and on the back of the tank.

As shown in FIG. 1 to FIG. 3, in the present embodiment, since the water tank 200 and the body base 100 are floatingly mounted, a certain gap is left between the two, and the self-moving ground processing device A is in the working process. Under the action of the gravity of the water tank 200 and the rag 210, the two can float in a certain spatial range, that is, float in a direction perpendicular to the ground. At this time, the rag 200 is in contact with the ground, and the force acting on the ground actually acts. Only the gravity of the water tank and the rag itself does not include the gravity of the body of the mobile ground handling device, so the friction between the rag and the ground is reduced compared with the ordinary product, which can effectively prevent the machine from slipping on the water ground. Improves floor cleaning efficiency. In addition, when the mobile ground processing device climbs the slope, since the water tank can float relative to the base of the body, one end of the water tank is not easy to jack up and get stuck, which significantly improves the climbing ability of the self-moving ground treatment device.

Embodiment 2

The difference between this embodiment and the first embodiment is that an elastic member is further disposed between the water tank 200 and the body base 100. The two ends of the elastic member are respectively positioned on the body base 100 and the water tank 200. Under the elastic support of the elastic member, a floating gap is left between the bottom surface of the body base and the outer top surface of the water tank. The elastic member may be a spring piece or a spring as needed. Of course, those skilled in the art may also perform other suitable structural selection according to the actual needs of the specific structure. For example, the elastic member is sleeved on the guide post to realize the body base and The elastic connection of the water tank.

The same principle as in the first embodiment, the elastic member used in the embodiment, the force acting on the ground during the movement of the self-moving ground treatment device A is the gravity of the water tank and the rag itself, but can further pass the elasticity. The elastic force of the piece finely adjusts the pressure between the rag and the ground. The self-moving ground treatment device keeps the friction between the rag and the ground in an optimal range, effectively preventing the slip phenomenon and improving the floor cleaning efficiency.

The other content in this embodiment is the same as the above embodiment, and details are not described herein again.
