Abstract

A cleaner and a cleaning device are disclosed. The cleaner includes: a guide rail; a lifting lever, one end of which is disposed on the guide rail and capable of moving along the guide rail; a feed pipe, disposed inside the lifting lever; and a nozzle, disposed on an end portion of one end of the lifting lever away from the guide rail and communicated with the feed pipe. The lifting lever is configured to allow the nozzle to be away from or close to the guide rail.

First claim

What is claimed is:

1. A cleaner, comprising:
a guide rail;
a lifting lever, one end of which is disposed on the guide rail and capable of moving along the guide rail;
a feed pipe, disposed inside the lifting lever; and
a nozzle, disposed on an end portion of one end of the lifting lever away from the guide rail and communicated with the feed pipe, wherein the lifting lever is configured to allow the nozzle to be away from or close to the guide rail, to increase or decrease a distance between the nozzle and the guide rail,
the lifting lever includes a first lifting lever, a second lifting lever, and a connecting piece connecting the first lifting lever and the second lifting lever,
the nozzle is disposed on an end portion of the first lifting lever, the second lifting lever is disposed on the guide rail, and the first lifting lever can perform an up-and-down movement relative to the second lifting lever.

2. The cleaner according to claim 1 , wherein the connecting piece is configured to rotate to drive the first lifting lever to perform the up-and-down movement relative to the second lifting lever.

3. The cleaner according to claim 1 , further comprising:
an inner spray head and an outer spray head,
wherein the inner spray head is disposed inside the outer spray head, the nozzle is disposed inside the inner spray head, a plurality of first spray holes are provided on the outer spray head, a plurality of second spray holes are provided on the inner spray head, and at least one of the inner spray head or the outer spray head is configured to rotate around the lifting lever.

4. The cleaner according to claim 3 , wherein the inner spray head is provided with a protruded slider which is arranged around an outer surface of the inner spray head and perpendicular to an axial direction of the lifting lever,
the outer spray head is provided with a recessed guide slot which is arranged around an inner surface of the outer spray head and perpendicular to the axial direction of the lifting lever, and
the protruded slider is embedded into the recessed guide slot and configured to move relative to the recessed guide slot.

5. The cleaner according to claim 1 , further comprising a multi-way valve disposed at one end of the lifting lever close to the guide rail,
wherein the multi-way valve is close to one end of the lifting lever close to the guide rail and communicated with the feed pipe.

6. A cleaning, comprising:
a guide rail;
a lifting lever, one end of which is disposed on the guide rail and capable of moving along the guide rail;
a feed pipe, disposed inside the lifting lever; and
a nozzle, disposed on an end portion of one end of the lifting lever away from the guide rail and communicated with the feed pipe, wherein the lifting lever is configured to allow the nozzle to be away from or close to the guide rail, to increase or decrease a distance between the nozzle and the guide rail, wherein the cleaner further comprises:
an inner spray head and an outer spray head,
wherein the inner spray head is disposed inside the outer spray head, the nozzle is disposed inside the inner spray head, a plurality of first spray holes are provided on the outer spray head, a plurality of second spray holes are provided on the inner spray head, and at least one of the inner spray head or the outer spray head is configured to rotate around the lifting lever.

7. The cleaner according to claim 6 , wherein an arrangement pitch of the second spray holes on the inner spray head is different from an arrangement pitch of the first spray holes on the outer spray head.

8. The cleaner according to claim 5 , further comprising a supporting rod connected with the one end of the lifting lever close to the guide rail,
wherein the multi-way valve is connected with one end of the supporting rod away from the lifting lever.

9. The cleaner according to claim 6 , wherein the inner spray head is provided with a protruded slider which is arranged around an outer surface of the inner spray head and perpendicular to an axial direction of the lifting lever,
the outer spray head is provided with a recessed guide slot which is arranged around an inner surface of the outer spray head and perpendicular to the axial direction of the lifting lever, and
the protruded slider is embedded into the recessed guide slot and configured to move relative to the recessed guide slot.
