Description

Technical Field

[0001] The utility model relates to the technical field of vacuum cleaners, and more specifically to a vacuum cleaner with a shock-absorbing function. Background Art

[0002] Vacuum cleaners can be divided into vertical, horizontal and portable types according to their structure, and are used to clean dust, dirt and other debris on the surface of floors, carpets, furniture, etc. Vacuum cleaners inhale air by generating negative pressure, sucking dust and dirt into the machine, and then releasing clean air back into the environment through the filtration system, thereby achieving a cleaning effect. However, in industrial production, it is necessary to keep the site clean at all times, and industrial vacuum cleaners are widely used at this time. Most industrial vacuum cleaners have high power, which easily leads to more serious noise, affecting the industrial production environment.

[0003] Industrial vacuum cleaners are powerful vacuum cleaners designed for use in industrial and commercial environments. They are usually used to clean large areas of dust, debris, liquids and other industrial waste. Compared with household vacuum cleaners, industrial vacuum cleaners usually have higher suction power, larger volume and stronger durability. Industrial vacuum cleaners are widely used in various industrial fields such as manufacturing, construction, logistics and warehousing. They can effectively improve the cleanliness of the production environment and ensure production safety and product quality.

[0004] The main reason why industrial vacuum cleaners generate noise is that the body will generate high-frequency vibrations during operation, thereby generating a lot of noise. The vacuum cleaners in the prior art have poor shock absorption performance. At the same time, when encountering potholes on uneven roads during vacuuming operations, the vacuum cleaner will shake, which is not conducive to vacuuming work and is prone to damage to the internal parts of the vacuum cleaner body, reducing the practicality of the device.

[0014] 1. The utility model is provided with a clamping sound-absorbing buffer mechanism and a shock-absorbing device, and the chassis body is placed on the top of the support plate, and then by starting the driving motor, the two clamping assemblies are driven to move relatively toward the middle, so that the two sides of the chassis body are pressed and fixed.

[0024] Reference Figure 1-6 The utility model provides a technical solution: a vacuum cleaner with a shock-absorbing function, comprising a bottom plate 1, a protective shell 2 is fixedly connected to the top of the bottom plate 1, mounting grooves 8 are symmetrically provided on both sides of the bottom of the inner cavity of the protective shell 2, and a shock-absorbing device 9 is arranged inside the mounting groove 8. The shock-absorbing device 9 comprises a sliding rod 91 arranged in the mounting groove 8, and second dampers 94 are symmetrically arranged at both ends of the sliding rod 91. A second spring 93 is sleeved on one end of the sliding rod 91 close to the second damper 94, and a sliding block 92 is movably sleeved on one end of the sliding rod 91 close to the second spring 93. A connecting rod 95 is hinged on the top of the sliding block 92, and a fixing block 96 is hinged on one end of the connecting rod 95 away from the sliding block 92. A clamping sound-absorbing cache mechanism 7 is fixedly connected to the top of the fixing block 96, and a chassis body 10 is arranged on the top of the clamping sound-absorbing cache mechanism 7. A dust suction pleated hose 3 is fixedly connected to one side of the chassis body 10, and a suction nozzle is arranged on one end of the dust suction pleated hose 3 extending to the outside through one side of the protective shell 2.

[0025] The two ends of the support plate 71 are pressed against the support frame 76, and the two ends of the support plate 76 are pressed against the support frame 76, so that the support frame 76 is pressed against the support frame 76. The connecting rod 95 drives the sliding blocks 92 at both ends to move along the sliding rod 91 toward both ends to squeeze the second spring 93. Through the interaction between the second spring 93 and the second damper 94, the vibration force generated by the chassis body 10 is easily absorbed, which plays a shock-absorbing role, thereby increasing the service life of the chassis body 10 and improving the practicality of the device.

Through the provided shock-absorbing support foot 5, the vibration force generated by the bumps squeezes the telescopic column 55, so that the telescopic column 55 presses down and squeezes the first spring 54. Then, through the interaction between the first damper 53 and the first spring 54, the vibration force of the bumps is absorbed, which plays a good shock-absorbing role, reduces the probability of internal parts being damaged by vibration, and achieves a good protection effect.

The end of the bidirectional screw 74 away from the drive motor 73 is connected to the bearing of the support plate 71. By starting the drive motor 73, the drive motor 73 drives the bidirectional screw 74 to rotate, and the bidirectional screw 74 drives the two movable blocks 75 to move relative to the middle, thereby driving the two clamping assemblies 76 to move relative to the middle.

[0029] In a preferred embodiment, the bottom plate 1 is fixedly connected with a push handle 4 away from the dust collection pleated hose 3, and the outer wall of the push handle 4 is fixedly sleeved with an anti-slip sleeve.

Through the interaction between the second spring 93 and the second damper 94, the vibration force generated by the chassis body 10 is easily absorbed, which plays a shock-absorbing role, thereby increasing the service life of the chassis body 10 and improving the practicality of the device. When the push handle 4 is pushed, the self-locking universal wheel 6 can be used to easily move the device for dust removal operations. When the self-locking universal wheel 6 passes through an uneven road surface, bumps will be generated. Through the provided shock-absorbing support foot 5, the vibration force generated by the bumps squeezes the telescopic column 55, so that the telescopic column 55 presses down and squeezes the first spring 54. Then, through the interaction between the first damper 53 and the first spring 54, the vibration force of the bumps is absorbed, which plays a good shock-absorbing role, reduces the probability of internal parts being damaged by vibration, and achieves a good protection effect.
