[0037] However, the environment in which the vacuum cleaner is used is relatively complex, such as light use at home or heavy use in factories and stores. If larger garbage, such as garbage bags, paper balls or stones, is encountered, direct suction will easily block the internal dust bag. Blockage will limit the suction power of the vacuum cleaner, resulting in a decrease in the cleaning effect and an inability to effectively remove dust, dirt and other debris. At the same time, long-term blockage may cause the motor to overheat or be damaged, shortening the life of the vacuum cleaner.

[0038] Based on this, the problem existing in the related technology that larger garbage may easily block the internal dust bag can be improved. The blockage will limit the suction power of the vacuum cleaner, resulting in a decrease in the cleaning effect. At the same time, long-term blockage may easily cause the motor to overheat, be damaged or burn out.

[0040] A dust box 2 is arranged inside the vacuum cleaner body 1 , and a mounting frame 7 is fixedly connected to the outer end of the vacuum cleaner body 1 .

[0041] The vacuum cleaner body 1 in this solution is provided with an electric motor, a power management device and the like. The electric motor is a power supply element, which drives the fan or blades to rotate and generate negative pressure, and the negative pressure sucks in air and dust through the suction port. A dust collecting box 2 is also provided inside the vacuum cleaner body 1. The dust collecting box 2 is mainly used to collect smaller garbage blocked by the dust collecting component 3. A connecting hose 2 6 is connected to the outer end of the vacuum cleaner body 1, and the other end of the connecting hose 2 6 is connected to the dust collecting component 3. The dust collecting component 3 is connected to the inside of the vacuum cleaner body 1 through the connecting hose 2 6 Next, a water collecting component 8 is provided at the bottom end of the dust collecting component 3, and a mounting frame 7 is fixedly installed on the outer end of the vacuum cleaner body 1. The water collecting component 8 is detachably installed in the mounting frame 7, so that the user can drag the entire device away when dragging the vacuum cleaner body 1. The inlet 32 ​​at the outer end of the collecting cylinder 31 is connected to a connecting hose 5, and the other end of the connecting hose 5 is connected to the suction head component 4, so that the negative pressure generated inside the vacuum cleaner body 1 can be transmitted to the suction head component 4, so that the garbage and dust can be sucked from the suction head component 4.

[0042] Optionally, in some embodiments, see Figure 4 The dust collecting assembly 3 also includes a collecting barrel 31 , and the top end of the collecting barrel 31 and the bottom end of the barrel cover 37 are both provided with mutually matching threads, and the barrel cover 37 and the collecting barrel 31 are threadedly connected.

[0043] A magnet is installed at the outer end of the mounting ring 33 . The connecting tube 35 is made of metal material. A plurality of filter screens 36 equidistantly distributed in an annular shape are arranged outside the connecting tube 35 .

[0044] An outlet 38 is provided at the top of the connecting tube 35, and the outlet 38 passes through the tube cover 37 and extends to the outside. The outer end of the outlet 38 is connected to the connecting hose 2 6, and an inlet 32 ​​is opened at the outer end of the collecting tube 31, and the inlet 32 ​​is connected to the connecting hose 1 5.

[0045] The shell of the dust collecting assembly 3 is mainly composed of a collecting barrel 31 and a barrel cover 37. The collecting barrel 31 and the barrel cover 37 are threadedly connected, so that they can be easily disassembled to clean the garbage inside. The inlet 32 ​​opened at the outer end of the collecting barrel 31 is used to connect the connecting hose 5. The inside of the barrel cover 37 is detachably connected with a connecting barrel 35. The top of the connecting barrel 35 penetrates the barrel cover 37 and extends to the outside to be connected with the connecting hose 6. A mounting ring 33 is installed at the bottom end of the connecting barrel 35. The mounting ring 33 is provided with a magnet at the outer end and is magnetically connected to the connecting barrel 35 made of metal, so as to achieve the purpose of convenient replacement. The suction force can prevent the mounting ring 33 from falling downward. At the same time, the diameter of the mounting ring 33 is larger than the diameter inside the connecting barrel 35, which can prevent it from being negatively charged. The suction is sucked into the connecting cylinder 35, and a filter screen 34 is installed on the mounting ring 33 to block larger garbage. Therefore, the filter hole of the filter screen 34 is larger to allow smaller garbage to pass through. A plurality of filter screens 36 distributed in a ring shape are also arranged outside the connecting cylinder 35. The filter screen 36 can provide a channel when the filter screen 34 is accidentally blocked, so that it can work for a period of time, prevent blockage from damaging the motor or other components, and improve the protection of the machine. By arranging a dust collecting component 3 between the suction head component 4 and the vacuum cleaner body 1, the dust collecting component 3 can collect larger garbage in advance before the garbage enters the dust collecting box 2, thereby reducing the probability that the dust collecting box 2 in the vacuum cleaner is blocked by large garbage, thereby ensuring the normal suction of the vacuum cleaner, so that it can efficiently clean dust and dirt.

[0046] Optionally, in some embodiments, see Figure 3 The suction head assembly 4 also includes a conduit 43, the bottom end of the conduit 43 is fixedly connected to the floor brush 41, the top end of the conduit 43 is connected to the connecting hose 5, and the floor brush 41 is connected to the connecting hose 5 through the conduit 43.

[0047] The suction head assembly 4 in this scheme is mainly composed of a conduit 43 and a floor brush 41. The top end of the conduit 43 is connected to a connecting hose 5, and the bottom end of the conduit 43 is connected to the floor brush 41. When in use, the user can move the floor brush 41 by holding the conduit 43 to suck out the garbage. An anti-blocking grille 42 is installed on the inner side of the bottom of the floor brush 41 to prevent some garbage bags or paper balls from being sucked in, thereby reducing the probability of blockage.

[0048] Optionally, in some embodiments, see Figure 5 The water collecting component 8 includes a water collecting bucket 81, the interior of the water collecting bucket 81 is hollow, the top of the water collecting bucket 81 and the bottom of the collecting tube 31 are both provided with threads, the collecting tube 31 is threadedly connected to the water collecting bucket 81, and a filter screen 82 is installed on the top of the water collecting bucket 81.

[0049] The water collecting bucket 81 is installed below the collecting tube 31 and is threadedly connected to the collecting tube 31 for easy disassembly. A filter screen 3 82 is installed at the connection between the water collecting bucket 81 and the collecting tube 31. When water is accidentally inhaled, the water will pass through the filter screen 3 82 and be collected in the water collecting bucket 81 due to its large gravity, thereby preventing water from entering the vacuum cleaner body 1 and reducing the probability of damage to the vacuum cleaner body 1.

[0050] Working principle: When using the device, the user can move the floor brush 41 by holding the guide tube 43 to suck up the garbage. First, the garbage will pass through the floor brush 41, the guide tube 43 and the connecting hose 15 into the collecting barrel 31. The inside of the barrel cover 37 is detachably connected to the connecting barrel 35, and the bottom end of the connecting barrel 35 is magnetically connected to the mounting ring 33. A filter 1 34 is installed on the mounting ring 33 to block larger garbage. Then smaller dust-like garbage will enter the dust collecting box 2 through the connecting hose 2 6 and be collected. A plurality of filter 2s 36 distributed in a ring shape are also arranged outside the connecting barrel 35. The filter 2 36 can provide a channel when the filter 1 34 is accidentally blocked to prevent the motor or other components from being damaged by the blockage. By arranging the dust collecting assembly 3 between the suction head assembly 4 and the vacuum cleaner body 1, larger garbage can be collected in advance to reduce the probability of blockage.

[0051] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
