Abstract

Provided is a cleaning device, comprising a wiper, a first clamping plate, a second clamping plate, a first elastic clamp and a second elastic clamp. The first clamping plate comprises a first plate body, a first bent portion and a first end portion. The first bent portion extends between the first plate body and the first end portion in a bent manner. The second clamping plate comprises a second plate body, a second bent portion and a second end portion. The second bent portion extends between the second plate body and the second end portion in a bent manner. The wiper is positioned between the first clamping plate and the second clamping plate. The cleaning device is moved relative to the nozzle to wipe the nozzle for cleaning. The wiper will not generate pollution and basically causes no wear to the nozzle.

First claim

What is claimed is:

1. A cleaning device for cleaning a nozzle, wherein a nozzle tip is configured with a spout communicating with inside and outside of the nozzle, wherein the cleaning device comprises a wiper, a first clamping plate, a second clamping plate, a first elastic clamp and a second elastic clamp, the first clamping plate comprises a first plate body, a first bent portion and a first end portion, the first bent portion extends between the first plate body and the first end portion in a bent manner, the second clamping plate comprises a second plate body, a second bent portion and a second end portion, the second bent portion extends between the second plate body and the second end portion in a bent manner, the wiper is positioned between the first clamping plate and the second clamping plate, the wiper comprises a fixed portion and a cleaning portion, the first bent portion and the second bent portion are held in a relatively clamped state by a clamping force of the first elastic clamp, the fixed portion of the wiper is clamped between the first bent portion and the second bent portion, the second elastic clamp is arranged between the first end portion and the second end portion to keep the first plate body and the second plate body in an inside clamping state, the cleaning portion is positioned between the first plate body and the second plate body to insert into the spout to clean the spout by clamping the nozzle with the first plate body and the second plate body and moving the cleaning device relative to the spout,
wherein the second elastic clamp is arranged between the first end portion of the first clamping plate and the second end portion of the second clamping plate to provide a tensile force to bias the first clamping plate and the second end portion of the second clamping plate outward so as to have the first plate body of the first clamping plate and the second plate body of the second clamping plate clamp the nozzle tip of the nozzle.

2. The cleaning device according to claim 1 , further comprising an additional first elastic clamp to pair with the first elastic clamp, wherein a bending direction of the first bent portion and a bending direction of the second bent portion are opposite to each other, a pair of first connecting buckles are provided on an edge of one side of the first bent portion facing the bending direction of the first bent portion, a pair of second connecting buckles are provided on an edge of one side of the second bent portion facing the bending direction of the second bent portion, the first elastic clamp are arranged in pairs and are respectively fixedly connected with the first connecting buckles and the second connecting buckles at both sides of the edges of the first bent portion and the second bent portion, an initial state of the first elastic clamp has a clamping force to the first bent portion and the second bent portion.

3. The cleaning device according to claim 2 , wherein the second elastic clamp is fixedly connected with the edges of the first end portion and the second end portion, the second elastic clamp applies the tensile force to the first end portion and the second end portion in an initial state, the first elastic clamp and the second elastic clamp grip the first clamping plate and the second clamping plate to form a gap between the first clamping plate and the second clamping plate, the gap receives the wiper.

4. The cleaning device according to claim 3 , wherein a thickness range of the wiper is from 0.08 mm to 0.12 mm and a width range of the gap is from 0.05 mm to 0.08 mm.

5. The cleaning device according to claim 4 , wherein a wiping sheet is arranged on the first clamping plate, the wiping sheet is positioned at a position on a surface of the first plate body fitting with the nozzle tip for wiping the nozzle tip.

6. The cleaning device according to claim 4 , wherein the first clamping plate is provided with a guiding slot, the guiding slot is positioned at a transitional position of the first plate body to the first bent portion for guiding flowing-out fluid of cleaning the nozzle of a knife.

7. The cleaning device according to claim 3 , wherein a wiping sheet is arranged on the first clamping plate, the wiping sheet is positioned at a position on a surface of the first plate body fitting with the nozzle tip for wiping the nozzle tip.

8. The cleaning device according to claim 3 , wherein the first clamping plate is provided with a guiding slot, the guiding slot is positioned at a transitional position of the first plate body to the first bent portion for guiding flowing-out fluid of cleaning the nozzle of a knife.

9. The cleaning device according to claim 3 , wherein the first clamping plate is provided with a hand-held portion, the hand-held portion is positioned on an outer surface of the first clamping plate to facilitate a hand-operated movement of the cleaning device.

10. The cleaning device according to claim 2 , wherein the first elastic clamp comprises a clamping end, two bent portions and two connecting ends, the clamping end, the two bent portions and the two connecting ends are sequentially connected and the bent portions and the connecting ends are at two sides of the clamping end.

11. The cleaning device according to claim 10 , wherein a wiping sheet is arranged on the first clamping plate, the wiping sheet is positioned at a position on a surface of the first plate body fitting with the nozzle tip for wiping the nozzle tip.

12. The cleaning device according to claim 10 , wherein the first clamping plate is provided with a guiding slot, the guiding slot is positioned at a transitional position of the first plate body to the first bent portion for guiding flowing-out fluid of cleaning the nozzle of a knife.

13. The cleaning device according to claim 2 , wherein a wiping sheet is arranged on the first clamping plate, the wiping sheet is positioned at a position on a surface of the first plate body fitting with the nozzle tip for wiping the nozzle tip.

14. The cleaning device according to claim 2 , wherein the first clamping plate is provided with a guiding slot, the guiding slot is positioned at a transitional position of the first plate body to the first bent portion for guiding flowing-out fluid of cleaning the nozzle of a knife.

15. The cleaning device according to claim 2 , wherein the first clamping plate is provided with a hand-held portion, the hand-held portion is positioned on an outer surface of the first clamping plate to facilitate a hand-operated movement of the cleaning device.

16. The cleaning device according to claim 1 , wherein at least one wiping sheet is arranged on the first clamping plate, the at least one wiping sheet is positioned at a position on a surface of the first plate body fitting with the nozzle tip for wiping the nozzle tip.
