Description

Technical Field

[0001] The utility model relates to the technical field of cleaning scrapers, in particular to a special scraper for cleaning range hoods. Background Technique

[0002] A range hood is a kitchen appliance, which simply means a device for extracting oil fumes. Its function is to purify the air environment in the kitchen. The earliest range hoods were mainly top-suction type, with the advantage of being very thin. Later, side-suction type range hoods appeared, with the advantage of good smoke suction effect. After long-term use, the surface of the range hood will be attached with oil stains and is difficult to clean. In most cases, a scraper is directly used for pretreatment and then an oil removal spray is used to improve the cleaning efficiency. However, there are still some problems when using the existing cleaning scrapers.

[0003] There is a special scraper for cleaning range hoods with the Chinese patent publication number CN213901203U, which includes a knife rod. The knife rod includes a main shaft section, a holding section, and an adjusting section from top to bottom. A scraper is hinged to the top of the main shaft section, and a wire cloth is bonded to the top of the scraper; a sleeve is sleeved outside the main shaft section, and an L-shaped slider is slidably connected to the outer wall of the sleeve. A support rod is hinged between the slider and the scraper; a nut block is rotatably connected inside the adjusting section, a semi-elliptical smooth rod is fixed to the bottom of the nut block, and a wire sleeve is sleeved on the lower end of the smooth rod. Although the existing special scraper for cleaning range hoods also has the function of adjusting the scraper head during use, it cannot be adjusted conveniently during use, and it is necessary to manually remove the scraper head to control the adjustment angle. During use, the scraper is easily contaminated by oil stains, and at the same time, it is not convenient to adjust the length of the handheld part of the scraper. When cleaning the higher part of the range hood, a climbing structure needs to be used, which increases the danger during use.

[0004] Therefore, we propose a special scraper for cleaning range hoods to solve the problems mentioned above. Content of the Utility Model

[0005] The purpose of the utility model is to provide a special scraper for cleaning range hoods to solve the problems in the above background technique that the existing cleaning scraper for range hoods is not convenient to adjust the length of the handheld part, and at the same time, the adjustment structure of the scraper head part is inconvenient to operate and is easy to cause pollution to clothes or limbs.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a special scraper for cleaning range hoods, including a positioning clip:

[0007] The upper end of the positioning clip is snap-connected with a scraper body, and a fixing plate is fixedly connected to the lower end of the middle part of the positioning clip. A first support tube is arranged at the lower end of the fixing plate, a second support tube is sleeved at the lower end of the first support tube, and an anti-slip sheath is installed at the lower end of the second support tube;

[0008] A sliding seat is slidably connected to the upper end of the first support tube, and the right end of the sliding seat extends to the outside of the first support tube and is connected to a support link, and the upper end of the support link is rotatably connected to a positioning clamp.

[0009] Preferably, the first support tube and the second support tube are slidably connected, and positioning holes are arrayed at the front end of the first support tube. A fixing bolt is embedded and installed on the upper side of the front end of the second support tube, and the rear end of the fixing bolt is embedded into the positioning hole, and the fixing bolt is threadedly connected to the positioning hole.

[0010] With the above technical solution, through the cooperation between the fixing bolt and the positioning hole, it is convenient to position the positions of the first support tube and the second support tube. At the same time, by using the cooperation between the fixing bolt and different positioning holes, the length of the handheld part can be adjusted.

[0011] Preferably, a positioning rod is fixed to the upper end of the first support tube. A positioning bolt is rotatably connected to the lower end of the positioning plate, and the lower end of the positioning bolt is threadedly connected to the positioning rod.

[0012] With the above technical solution, through the threaded cooperation between the positioning bolt and the positioning rod, it is convenient to connect the scraper blade part and the handheld part.

[0013] Preferably, a slider is slidably connected to the right end of the positioning rod, and a limiting column is fixed to the upper end of the slider. A positioning plate is fixed to the top end of the positioning bolt, and the upper end of the limiting column penetrates into the positioning plate. A guide rod penetrates through the slider, and both ends of the guide rod are fixed to the inner wall of the positioning rod. A return spring penetrates through the lower end of the guide rod, and the upper and lower ends of the return spring are respectively fixed to the slider and the inner wall of the positioning rod.

[0014] With the above technical solution, through the design of the return spring, the slider and the limiting column can be pushed to move upward, and the limiting column is engaged with the positioning plate upward to limit the change of the angle between the positioning rod and the positioning bolt, so as to prevent loosening.

[0015] Preferably, a threaded lead screw is arranged inside the upper end of the first support tube, and the threaded lead screw is rotatably connected to the inner wall of the first support tube. The sliding seat is slidably connected to the first support tube, the threaded lead screw penetrates through the sliding seat, and the sliding seat is threadedly connected to the threaded lead screw.

[0016] With the above technical solution, through the design of the threaded lead screw, the position of the sliding seat can be limited. When the threaded lead screw rotates, the positions of the sliding seat and the support link can be driven to change, so as to change the angle of the positioning clamp and the scraper blade body.

[0017] Preferably, a first transmission rod is fixedly connected to the lower end of the threaded lead screw, and a second transmission rod is sleeved on the lower end of the first transmission rod. The lower end of the second support tube is rotatably connected to a turntable, and the upper end of the turntable extends into the second support tube and is fixedly connected to the second transmission rod. The first transmission rod is slidably connected to the second transmission rod, and both the second transmission rod and the first transmission rod are designed with a square structure.

[0018] With the above technical solution, by rotating the turntable, the second transmission rod and the first transmission rod can be driven to rotate synchronously, and the threaded rod can be driven by the first and second transmission rods to adjust the position of the sliding seat, so that the angle of the scraper can be conveniently adjusted during use.

[0019] Compared with the prior art, the beneficial effects of the present utility model are: the special scraper for cleaning the range hood;

[0020] 1.
