[0002] As people's modern lives become more intelligent, the variety of household appliances is also increasing. After long-term use, delicate household appliances are prone to dust accumulation and wear and tear, which affects their appearance and shortens their lifespan.

[0003] To further understand existing household appliance cleaning devices, a search revealed Chinese patent CN217528398U, which discloses a tea roasting machine. The machine includes a base, a dust collection box mounted on top of the base, a rubber hose fixedly connected to the top of the dust collection box, and a dust inlet box fixedly connected to the top of the rubber hose. A first support plate and a second support plate are fixedly connected to the left and right ends of both the dust collection box and the dust inlet box. A first electric telescopic rod is fixedly connected between the first and second support plates. A filter plate is fixedly connected to the inner cavity of the dust inlet box, and a drive motor is mounted on the filter plate. A second electric telescopic rod is fixedly mounted on the motor shaft of the drive motor, and a cleaning brush is mounted on the top of the second electric telescopic rod. A folded dust-proof cloth tube is fixedly connected to the top of the dust inlet box, and an elastic ring is fixedly connected to the top of the folded dust-proof cloth tube. A negative pressure pump is mounted on the top right side of the base, and an air suction pipe is fixedly connected to the negative pressure pump. The air suction pipe passes through the dust collection box and is placed inside the dust collection box. An air filter passes through the outside of the air suction pipe inside the dust collection box.

[0004] After exploration and analysis, the patent has the following drawbacks in actual use: Although the height of the dust box can be adjusted by the first electric telescopic rod to clean appliances of different heights, the dust box in the patent can only clean the front and sides of household appliances. It cannot clean the top of household appliances with a certain height (refrigerator, air conditioner, etc.), which reduces the practicality of the device. Cleaning the dust on the top of household appliances at a height requires people to climb up to operate, which poses a safety hazard. Utility Model Content

[0005] To address the technical problems of existing devices being unable to clean the tops of household appliances (refrigerators, air conditioners, etc.) that are at a certain height, thus reducing their practicality, and requiring people to climb to clean the dust accumulated on the tops of high-altitude household appliances, which poses safety hazards, this utility model provides a highly efficient cleaning device for household appliances.

[0027] The following is in conjunction with the appendix Figure 1 - Appendix Figure 7 The present invention will be further described below.

[0028] To address the problems existing in the background art, this application proposes the following technical solution: It includes a first cleaning rod 1, a connecting rod 2, and a first hinge block 5 and a second hinge block 6 fixedly connected to both ends of the connecting rod 2. The upper end of the first cleaning rod 1 is rotatably mounted in the first hinge block 5. A first fixing screw 7 is rotatably mounted on the first hinge block 5, and a first fixing nut 8 is threaded onto the first fixing screw 7. A mounting frame 3 is rotatably mounted in the second hinge block 6, and a dust-adhesive roller 4 is rotatably mounted on the mounting frame 3. A second fixing screw 9 is rotatably mounted on the second hinge block 6, and a second fixing nut 10 is threaded onto the second fixing screw 9.

[0029] The first cleaning rod 1 and the mounting bracket 3 are rotatably mounted on both ends of the connecting rod 2 via the first hinge block 5 and the second hinge block 6. The first fixing screw 7 and the first fixing nut 8 are used to fix the positions of the first cleaning rod 1 and the connecting rod 2. The second fixing screw 9 and the first cleaning rod 1 are used to fix the positions of the connecting rod 2 and the mounting bracket 3. When cleaning dust from the front and sides of the household appliance, the connecting rod 2 is rotated to a vertical position, and the first fixing screw 7 is tightened to fix one end of the connecting rod 2 to the upper end of the first cleaning rod 1. The mounting bracket 3 is rotated to be perpendicular to the connecting rod 2, and the second fixing screw 9 is tightened to fix the mounting bracket 3 to the other end of the connecting rod 2 (as shown in the attached figure). Figure 7As shown in the diagram, the first cleaning rod 1, in conjunction with the connecting rod 2 and the mounting bracket 3, drives the sticky roller 4 to roll on the front and sides of the household appliance. The sticky roller 4 is composed of adhesive-coated sticky paper rolled onto a paper core. The sticky paper adsorbs accumulated dust through its adhesiveness. During cleaning, the sticky roller 4 rolls in the same direction to avoid incomplete cleaning or dust falling off due to back-and-forth wiping. When cleaning the top of the household appliance, rotate the connecting rod 2 to a horizontal position and tighten the first fixing screw 7 to secure it. Rotate the mounting bracket 3 to be parallel to the connecting rod 2 and tighten the second fixing screw 9 to secure it (as shown in the attached diagram). Figure 1 As shown, the first cleaning rod 1 drives the sticky roller 4 to roll on top of the household appliance to clean the dust accumulated on the top. This avoids cleaning dead corners on the top of the household appliance, which is located at a high position, and also avoids people having to climb to clean the top of the household appliance, thus improving the safety of the cleaning operation. The sticky roller 4 is a tearable sticky roller, with adhesive sticky paper pre-cut in sections. When the surface of the sticky roller 4 gets dirty, the outer layer can be peeled off, which ensures the cleaning effect of the sticky roller 4 when used frequently and improves the convenience of using the cleaning device.

[0030] Furthermore, a mounting plate 11 is detachably mounted on one side of the mounting frame 3. Fixing blocks 12 are rotatably mounted on the opposite side of the mounting plate 11 and the mounting frame 3. The dust roller 4 is installed between the two sets of fixing blocks 12.

[0031] After the adhesive paper on the sticky roller 4 is peeled off, remove the mounting plate 11 from one side of the mounting frame 3. Remove the used paper core of the sticky roller 4 from between the two sets of fixing blocks 12. After replacing the sticky roller 4 with a new one, put the mounting plate 11 back into one side of the mounting frame 3. It can then be used again. By performing the above operations, after the sticky roller 4 is used up, only the sticky roller 4 needs to be replaced. The mounting frame 3 can continue to be used, reducing the operating cost of the cleaning device and improving the practicality of the device.

[0032] Furthermore, a slot 13 is provided on one side of the mounting bracket 3, and a plug 14 is fixedly connected to one side of the mounting plate 11. The plug 14 and the slot 13 cooperate with each other. Two sets of mounting grooves 15 are provided in the plug 14. A locking post 16 is slidably connected in each of the two sets of mounting grooves 15. A return spring 18 is fixedly connected to one end of the locking post 16. One end of the return spring 18 is fixedly installed in the mounting groove 15. A locking hole 17 is provided on the mounting bracket 3. The locking hole 17 is adapted to the locking post 16.

[0033] When the used sticky roller 4 needs to be replaced, the locking pin 16 is pressed into the mounting groove 15 through the locking hole 17. The locking pin 16 compresses and deforms the return spring 18, releasing the restriction of the locking pin 16 on the insertion block 14. The insertion block 14 is pulled out of the slot 13, and the mounting plate 11 is moved away from one side of the mounting bracket 3. The sticky roller 4 is removed from between the two sets of fixing blocks 12. After the new sticky roller 4 is placed between the two sets of fixing blocks 12, the mounting plate 11 is pushed to move, so that the insertion block 14 is inserted into the slot 13. The locking pin 16 is released, and the compressed return spring 18 pushes the locking pin 16 into the locking hole 17 to return to its initial state. The locking pin 16, together with the locking hole 17, fixes the insertion block 14 in the slot 13, so that the sticky roller 4 is stably installed between the two sets of fixing blocks 12. The detachable installation of the mounting plate 11 facilitates the replacement and installation of the sticky roller 4 and improves the convenience of using the device.

[0034] Furthermore, an anti-detachment groove 19 is provided on one side of the mounting plate 11, and an anti-detachment head 20 is rotatably installed in the anti-detachment groove 19. One end of the anti-detachment head 20 is fixedly connected to the fixing block 12.

[0035] The anti-detachment round head 20, together with the anti-detachment round groove 19, limits the rotation of the fixing block 12, so that the fixing block 12 is stably installed on one side of the mounting plate 11. The fixing block 12 of the mounting frame 3 is installed in the same way, which improves the stability of the dust roller 4 when it rotates during the use of the device.

[0036] To further explain, a second cleaning rod 21 is sleeved on the outside of the first cleaning rod 1. The upper end of the second cleaning rod 21 is provided with an internal thread 22. The outside of the first cleaning rod 1 is fixedly connected with a first external thread 23 and a second external thread 24. The first external thread 23 and the second external thread 24 are used in conjunction with the internal thread 22.

[0037] When cleaning lower-level household appliances, the first cleaning rod 1 is locked in the second cleaning rod 21 by the engagement of the second external thread 24 and the internal thread 22, thus reducing the overall length of the device (as shown in the attached diagram). Figure 7 (As shown), this makes the dust roller 4 more flexible and convenient for cleaning lower-level household appliances. When cleaning higher-level household appliances, the locking between the second external thread 24 and the internal thread 22 is released, and the first cleaning rod 1 is pulled out from the second cleaning rod 21. Through the engagement of the first external thread 23 and the internal thread 22, the bottom of the first cleaning rod 1 is locked in the second cleaning rod 21, increasing the overall length of the device (as shown in the attached figure). Figure 1 As shown in the figure, it facilitates the cleaning of household appliances at high places. By adjusting the overall length of the device, it can clean household appliances at different heights, improving the flexibility and convenience of the device.

[0038] The adhesive roller 4, first fixing screw 7, first fixing nut 8, second fixing screw 9 and second fixing nut 10 of this utility model for a high-efficiency cleaning device for household appliances are commercially available and are existing technologies. Technicians in this industry only need to install and operate them according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.

[0039] For specific operation, please refer to the following instructions: When cleaning the top of a high-mounted household appliance, rotate the connecting rod 2 to a horizontal position and tighten the first fixing screw 7 to fix the connecting rod 2 to the upper end of the first cleaning rod 1. Rotate the mounting bracket 3 to be parallel to the connecting rod 2 and tighten the second fixing screw 9 to fix the mounting bracket 3 under the connecting rod 2. Then, pull the first cleaning rod 1 out from the second cleaning rod 21. Through the engagement of the first external thread 23 and the internal thread 22, the bottom of the first cleaning rod 1 is locked in the second cleaning rod 21, increasing the overall length of the device. The second cleaning rod 21 drives the sticky roller 4 to roll in the same direction on the top of the household appliance to clean the top of the appliance. After the surface of the sticky roller 4 is covered with dust, peel off the adhesive paper coating on its surface to maintain the sticky roller 4's efficient dust adhesion effect.
