Abstract

The position arrival switch assembly is assembled to the automatic cleaning apparatus, and is configured to indicate whether the automatic cleaning apparatus returns to a predetermined position of a pile body. The position arrival switch assembly includes: a switch component; a button, which is configured to move toward the switch component under the action of an external force; an elastic arm, which extends in a direction away from the button from the face of the button that faces the switch component; and a switch trigger piece, which is connected to the end of the elastic arm that is away from the button, wherein the switch component is configured to send a position arrival signal in response to being triggered by the switch trigger piece.

First claim

1 . A position arrival switch assembly configured for use with an automatic cleaning apparatus and configured to determine whether the automatic cleaning apparatus is to return to a predetermined position of a pile body, the position arrival switch assembly comprising:
a switch component; a button, configured to move toward the switch component under an action of an external force; an elastic arm, extending in a direction away from the button from a face of the button that faces the switch component; and a switch trigger piece, connected to an end of the elastic arm away from the button, wherein the switch component is configured to send a position arrival signal in response to being triggered by the switch trigger piece.

2 . The position arrival switch assembly according to claim 1 , wherein the switch component comprises:
a switch component body; and an elastic component, extending toward the button from a side face of the switch component body that faces the button, wherein in response to movement of the button toward the switch component, the switch trigger piece squeezes the elastic component to enable the elastic component to be compressed; and in response to the elastic component being compressed by a predetermined amount, the switch component sends the position arrival signal.

3 . The position arrival switch assembly according to claim 2 , further comprising: a position limit member, arranged on a side of the switch component body that faces the button, and configured to block the switch trigger piece from continuously compressing the elastic component in response to the elastic component being compressed by the predetermined amount.

4 . The position arrival switch assembly according to claim 1 , further comprising: a slide rail, configured to support the switch trigger piece, such that the switch trigger piece is slidable on the slide rail.

5 . The position arrival switch assembly according to claim 1 , wherein the elastic arm is of a bending structure, the bending structure comprises a first end, a second end, and a bending part located between the first end and the second end; the first end is connected to the button; and the second end is connected to the switch trigger piece.

6 . The position arrival switch assembly according to claim 1 , wherein a quantity of the elastic arm is at least two, and the at least two elastic arms are symmetrically arranged relative to a median line of the button.

7 . The position arrival switch assembly according to claim 1 , wherein at least one raised structure is arranged on a top surface of the button.

8 . The position arrival switch assembly according to claim 1 , wherein the button comprises:
a pressing part; a first sub-part, strip-shaped and arranged on a side of the pressing part that faces the switch component, wherein a middle part of the first sub-part is connected to the pressing part; and a second sub-part and a third sub-part, extending toward the switch component in a direction substantially perpendicular to the first sub-part from two ends of the first sub-part, respectively, wherein at least one of the second sub-part and the third sub-part is configured to slide on a guide rail along with movement of the button.

9 . The position arrival switch assembly according to claim 8 , wherein a compression spring is arranged between an end of the guide rail that is away from at least one of second sub-part and the third sub-part and a free end of at least one of the second sub-part and the third sub-part.

10 . An automatic cleaning apparatus, comprising a position arrival switch assembly configured to determine whether the automatic cleaning apparatus is to return to a predetermined position of a pile body, and the position arrival switch assembly comprises:
a switch component; a button, configured to move toward the switch component under an action of an external force; an elastic arm, extending in a direction away from the button from a face of the button that faces the switch component; and a switch trigger piece, connected to an end of the elastic arm away from the button, wherein the switch component is configured to send a position arrival signal in response to being triggered by the switch trigger piece.

11 . The automatic cleaning apparatus according to claim 10 , comprising:
a mobile platform; and a liquid storage tank, detachably arranged in the mobile platform, wherein the position arrival switch assembly is arranged on a side of the liquid storage tank that faces a bottom surface of the mobile platform.

12 . The automatic cleaning apparatus according to claim 11 , wherein the mobile platform comprises a forward portion and a rearward portion, and both the liquid storage tank and the position arrival switch assembly are arranged in the rearward portion.

13 . The automatic cleaning apparatus according to claim 11 , wherein a slot is formed in a side wall of the mobile platform, and is located below the liquid storage tank; and the pressing part of the button is arranged in the slot.

14 . A method, comprising:
providing a position arrival switch assembly configured for use with an automatic cleaning apparatus, the position arrival switch assembly being configured to determine whether the automatic cleaning apparatus is to return to a predetermined position of a pile body, wherein the position arrival switch assembly comprises: a switch component; a button configured to move toward the switch component under an action of an external force; an elastic arm extending in a direction away from the button from a face of the button that faces the switch component; and a switch trigger piece connected to an end of the elastic arm away from the button, wherein the switch component is configured to send a position arrival signal in response to being triggered by the switch trigger piece.

15 . The method according to claim 14 , further comprising providing the automatic cleaning apparatus, wherein the position arrival switch assembly is arranged on the automatic cleaning apparatus.

16 . The method according to claim 15 , wherein the switch component comprises:
a switch component body; and an elastic component, extending toward the button from a side face of the switch component body that faces the button, wherein in response to movement of the button toward the switch component, the switch trigger piece squeezes the elastic component to enable the elastic component to be compressed; and in response to the elastic component being compressed by a predetermined amount, the switch component sends the position arrival signal.

17 . The method according to claim 16 , further comprising: a position limit member, arranged on a side of the switch component body that faces the button, and configured to block the switch trigger piece from continuously compressing the elastic component in response to the elastic component being compressed by the predetermined amount.

18 . The method according to claim 15 , further comprising: a slide rail, configured to support the switch trigger piece, such that the switch trigger piece is slidable on the slide rail.

19 . The method according to claim 15 , wherein the elastic arm is of a bending structure, the bending structure comprises a first end, a second end, and a bending part located between the first end and the second end; the first end is connected to the button; and the second end is connected to the switch trigger piece.
