Description

Technical Field

[0001] The utility model relates to the technical field of vacuum cleaners, in particular to a vacuum cleaner structure capable of turning corners and orienting corners. Background Art

[0002] A vacuum cleaner is a household cleaning appliance that uses an electric motor to drive the rotating blades to generate airflow, drawing dust and debris from the floor or other surfaces. A filtration system separates the air from the debris, ultimately collecting the debris in a dust bag or dust bin. It effectively removes all types of dirt, maintaining a clean and hygienic home environment. Modern vacuum cleaners also feature a variety of accessories and intelligent technologies, such as HEPA filtration, wireless operation, and automatic cleaning, to meet the cleaning needs of different users.

[0003] Existing vacuum cleaners are all connected to the vacuum cleaner with a hose to increase the effective cleaning range of the vacuum cleaner. For example, Chinese patent document "CN220459274U, an ultra-small handheld vacuum cleaner with an extendable suction rod" is disclosed. This vacuum cleaner extends the suction rod by installing a vacuum hose on the vacuum rod, making it more convenient to clean dust. However, in order to ensure that the vacuum cleaner can effectively absorb dust and debris during use, the end of the vacuum hose must be tightly gripped by hand. During long-term use, continuously holding the hose will undoubtedly put significant pressure on the user's hands, causing hand muscle fatigue and even pain. In addition, if the vacuum hose is not stabilized by manual grip, then when the vacuum cleaner is working, the hose will swing around due to the strong suction force, which will not only reduce the cleaning efficiency, but also fail to accurately aim at the area to be cleaned, thereby affecting the cleaning effect.

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0026] Please refer to Figure 1-8 ;

[0027] The utility model discloses a rotatable directional structure of a vacuum cleaner, comprising a vacuum cleaner body 1, a suction port 11 being provided at one end of the vacuum cleaner body 1, the suction port 11 being connected to a universal shaping tube 2, and a brush 3 being connected at the other end of the universal shaping tube 2 for changing and fixing the direction of the brush 3. Preferably, the universal shaping tube 2 of this embodiment can be specifically referred to the public technical document "202221981656.2, a universal shaping suction device". The universal shaping tube 2 can change its shape by applying external force. When no external force is applied, the universal shaping tube 2 maintains the new direction unchanged, allowing the user to adjust the direction of the universal shaping tube 2 according to actual needs. The characteristics of being shapeable and able to maintain a new shape enable the user to flexibly adjust its suction direction to adapt to various cleaning needs, such as cleaning the bottom of furniture, corners or high places that are difficult to reach. At the same time, the angle can be fixed after adjustment, and there is no need to continuously support it with hands, which saves energy. The air inlet 32 ​​is connected to the external environment for sucking in dust and particles. The inner wall of the chamber 33 is an arc-shaped structure for temporarily storing dust and debris sucked from the floor or other surfaces. Dust and debris can slide into the air inlet 34 along its inner wall, which helps to keep the suction pipe unobstructed, prevent excessive garbage from clogging the pipe and affecting the overall performance of the vacuum cleaner, and improve the cleaning experience. The air inlet 34 is connected to the universal shaping tube 2 for transporting the sucked in dust and particles to the vacuum cleaner body. A number of bristles 31 are provided on the surface of the brush 3. The bristles 31 are located on the periphery of the air inlet 32. The bristles 31 can loosen and remove dirt on the floor and other surfaces through physical friction, while bringing out hidden dust and particles, helping the vacuum cleaner to complete the cleaning task more effectively.

[0028] In order to improve the dust collection effect, the air inlet 32 ​​includes a small opening 321 and a large opening 322 symmetrically arranged. The small opening 321 corresponds to the air inlet duct 34, directly absorbing fine dust to ensure that fine particles are efficiently removed first. The large opening 322 can absorb larger particles and debris. The particles and debris absorbed by the large opening 322 will slide along the inner wall of the chamber 33 into the air inlet duct 34, achieving efficient and comprehensive cleaning.

[0029] In this embodiment, in order to facilitate the installation and disassembly of the universal shaping tube 2, a plurality of "J"-shaped slots 21 are distributed in a ring at one end of the universal shaping tube 2 connected to the air intake port 11, and a plurality of plug-in blocks 12 corresponding to the slots 21 are provided on the inner side wall of the air intake port 11. Preferably, there are four slots 21 and four plug-in blocks 12 respectively. The slot 21 includes an insertion portion 211, a rotating portion 212 and a plug-in portion 213 that are connected in sequence. The plug-in block 12 is inserted from the insertion portion 211, rotates on the rotating portion 212, and is finally plugged into the plug-in portion 213 to achieve a fixed connection between the universal shaping tube 2 and the air intake port 11.

[0030] Specifically, align the insertion portion 211 on the universal shaping tube 2 with the insertion portion 211 and insert it to the bottom, then rotate the universal shaping tube 2 so that the plug block 12 rotates along the rotating portion 212 to a position corresponding to the plug-in portion 213, and finally push the universal shaping tube 2 forward so that the plug block 12 is inserted into the plug-in portion 213 to achieve the installation of the universal shaping tube 2. If you want to disassemble it, you only need to move the universal shaping tube 2 backward so that the plug block 12 is separated from the plug-in portion 213 and is located in the rotating portion 212, and then rotate the universal shaping tube 2 in the opposite direction until the plug block 12 corresponds to the insertion portion 211, and then you can directly pull out the universal shaping tube 2 to achieve the disassembly of the universal shaping tube 2.

[0031] In order to increase the sealing effect between the universal shaping tube 2 and the air intake port 11, an annular groove 23 is further provided at one end where the universal shaping tube 2 is connected to the air intake port 11, and a sealing rubber ring 231 is placed on the annular groove 23. The sealing rubber ring 231 abuts against the inner wall of the air intake port 11, thereby achieving the sealing between the universal shaping tube 2 and the inner wall of the air intake port 11. At the same time, since the rubber sealing gasket also has the effect of increasing friction, the stability of the connection between the universal shaping tube 2 and the air intake port 11 is ensured.

[0032] In this embodiment, one end of the universal shaping tube 2 connected to the brush 3 is provided with a slot 22 that is symmetrical in upper and lower directions, and the outer surface of the brush 3 is provided with a block 36 that is symmetrical in upper and lower directions. The brush 3 is made of a plastic material with deformable properties. During installation, the brush 3 is inserted into the universal shaping tube 2. During the insertion process, the block 36 is subjected to the pressure of the universal shaping tube 2, causing the upper and lower surfaces of the brush 3 to deform. When the block 36 is aligned with the slot 22, the upper and lower surfaces of the brush 3 return to their original state, and the block 36 is automatically inserted into the slot 22 to complete the installation of the brush 3. Preferably, the slot 22 and the block 36 are triangular structures that adapt to each other, so that the user can directly pull out the brush 3.

[0033] In order to increase the sealing effect between the universal shaping tube 2 and the brush 3, an annular groove 2 35 is provided at one end where the brush 3 is connected to the universal shaping tube 2, and a sealing rubber ring 351 is provided on the annular groove 35. The sealing rubber ring 351 abuts against the inner wall of the universal shaping tube 2, thereby achieving sealing between the brush 3 and the inner wall of the universal shaping tube 2. At the same time, since the rubber sealing gasket also has the effect of increasing friction, the stability of the connection between the brush 3 and the universal shaping tube 2 is ensured.

[0034] In this embodiment, the universal shaping tube 2 is covered with an anti-slip rubber sleeve 4. The anti-slip rubber sleeve 4 not only greatly improves the user's grip comfort when operating the vacuum cleaner, but also effectively prevents hand slippage caused by hand sweat or a wet and slippery environment.
