Abstract
Description
Technical Field
[0001] The utility model relates to a daily sundry product, in particular to a dustpan which relies on gravity to complete dumping. Background Art
[0002] In the cleaning industry, dustpans, as traditional cleaning tools, have experienced a long history of use. However, with the progress of the times, people's needs for cleaning tools are also changing. Although the traditional dustpan design can meet basic cleaning needs, there are some obvious problems when dumping garbage and dust. These problems not only affect the efficiency of cleaning work, but also bring a lot of inconvenience to users. Therefore, improving the design of dustpans to meet the cleaning needs of modern people has become an urgent problem to be solved in the cleaning industry.
[0003] Traditional dustpan designs often rely on manual dumping, which not only requires users to spend more time and energy, but also causes garbage and dust to scatter easily during the dumping process, causing secondary pollution. In order to solve this problem, some designers have tried to add mechanical devices to dustpans to achieve automatic dumping. However, these designs are often complex in structure and cumbersome in operation, which not only increases manufacturing costs but also reduces the convenience of use.
[0004] In this context, the utility model proposes a new dustpan design. The solution sets a fixed gear on the rear side of the dustpan body, and controls the dumping of the dustpan body by engaging and separating the rotating engaging teeth with the fixed gear. At the same time, in order to simplify the operation, the design adopts a structure of a wire rope and an opening and closing handle. The user only needs to gently pull the opening and closing handle to drive the rotating engaging teeth to move upward through the wire rope, so as to separate from the fixed gear, thereby easily dumping the garbage.
[0005] This design is not only simple in structure, but also easy to operate. The user does not need to perform complicated operations, but only needs to pull the dustpan to dump. At the same time, due to the principle of mechanical transmission, the dustpan can maintain stability during the dumping process, avoiding the scattering of garbage and dust, and improving the efficiency and quality of cleaning work. Utility Model Content
[0006] The purpose of the utility model is to overcome the deficiencies of the prior art and to provide a multifunctional dustpan which can not only dump garbage by itself but also is not easily stuck by large garbage.
[0007] The utility model comprises a dustpan body, a pipe column and a handle, a fixed gear is provided on the rear side of the dustpan body, the fixed gear is engaged with the rotating engaging teeth, connecting ears are provided on both sides of the fixed gear, a support arm is provided on the connecting ear, a pipe column is provided on the support arm, the pipe column is configured as a hollow sleeve, an opening and closing handle is provided at the upper end, a fixed handle is provided at the upper end of the opening and closing handle, and the lower end is fixed on the support arm, an opening and closing handle and a steel wire pull rope are provided in the pipe column, the upper end of the pull rope is fixedly connected to the opening and closing handle, and the lower end is fixedly connected to the rotating engaging teeth.
[0008] In the above technical solution, preferably, the pipe column is configured as a hollow casing, an opening and closing handle is provided at the upper end, a support arm is provided at the lower end, and the support arm is connected to the dustpan connecting ear on the rear side of the dustpan body.
[0009] In the above technical solution, preferably, one end of the wire rope is fixedly connected to the opening and closing handle, and the other end is fixedly connected to the rotating engaging tooth. By operating the opening and closing handle, the wire rope can be driven to separate or engage the rotating engaging tooth with the fixed gear.
[0010] In the above technical solution, preferably, the length ratio of the pipe column to the dustpan body is 5:1.
[0011] In the above technical solution, preferably, the distance between the opening and closing handle and the fixed handle is 5 cm.
[0012] In the above technical solution, preferably, when the rotating engaging teeth are separated from the fixed gear, the dustpan body is unlocked and can be tilted forward; when the rotating engaging teeth are engaged with the fixed gear, the dustpan body is locked in place.
[0013] In the above technical solution, preferably, the dustpan body, the pipe column, the handle and the dumping mechanism are all made of lightweight and durable materials to reduce the overall weight and increase the service life.
[0014] When in use, lift the opening and closing handle upwards, and the opening and closing handle drives the steel wire pull rope upwards, and the steel wire pull rope drives the rotating engaging teeth upwards, and the rotating engaging teeth stop engaging with the fixed gear. If the dustpan is in the air at this time, the dustpan body will tilt forward to pour out the garbage and dust. After use, put the dustpan back on the ground, release the opening and closing handle, and the steel wire pull rope drives the rotating engaging teeth downwards, and the rotating engaging teeth engage with the fixed gear again.
[0015] The beneficial effect of the utility model is that by adding fixed gears, rotating meshing teeth, steel wire ropes, opening and closing handles and other components, the utility model realizes the automatic dumping function of the dustpan body. This design greatly simplifies the operation steps of dumping garbage. Users can easily complete the dumping by simply pulling and lifting, without manually tilting the dustpan body, which greatly improves the efficiency of cleaning work.
[0016] This design effectively reduces the risk of dumping garbage. Traditional dumping methods often cause garbage to scatter and even dirty hands, causing unnecessary troubles to users. The utility model avoids these problems by precisely controlling the dumping angle and force, ensuring the accuracy and stability of dumping, and providing users with a safer and more convenient use experience.
[0017] From the perspective of cost, the design of the utility model fully considers the control of production cost. Through reasonable material selection and structural design, the production cost is reduced, so that the dustpan can be marketed at a more affordable price to meet the needs of the majority of users.
