[0038] During the plastics production process, the addition of various material powders not only pollutes the environment, but also makes operators vulnerable to inhaling dust, which can cause health problems. Furthermore, dust drifts into the air, making it difficult to clean. Therefore, industrial vacuum cleaners are commonly used to clean dust from production sites.
[0039] Traditional industrial vacuum cleaners consist of a dust box and a vacuum motor. The vacuum motor is housed in the dust box and equipped with a filter. When the vacuum motor operates, negative pressure is generated inside the dust box, drawing dust from outside the dust box into the dust box. Once inside, the filter blocks the dust from entering the vacuum motor, protecting it.
[0040] However, when the dust in the traditional dust box needs to be cleaned, the filter on the vacuum motor must be removed and the dust on the filter must be cleaned before the dust in the dust box is cleaned. The whole process is cumbersome and can easily cause the operator to inhale the dust again.
[0041] In this regard, an embodiment of the present application provides a vacuum cleaner 10, which can be an industrial vacuum cleaner, for example, for cleaning dust, dirt and other foreign matter at a processing site of plastics, etc. Of course, the vacuum cleaner 10 can also be a household vacuum cleaner.
[0042] The vacuum cleaner 10 has a vacuuming mode and a self-cleaning mode. Figure 1 and Figure 2 As shown, the housing 100 may include a power element 200, a first filter element 300, and a dust exhaust pipe 400. The housing 100 serves as a mounting carrier for the various components of the vacuum cleaner 10 and has a dust collection chamber 100a and an air inlet, an exhaust port, and a dust exhaust port communicating with the dust collection chamber 100a. This application does not impose any specific restrictions on the size of the housing 100, as long as it can meet the normal dust removal requirements of the processing site. For example, the housing 100 may have a diameter of approximately 70 cm and a height of approximately 1 meter.
[0043] Alternatively, as Figure 1As shown, the box body 100 includes a base 160, a box body 140 and a top cover 150. The box body 140 is arranged on the base 160 and is configured as a cylindrical structure with an opening at the top and a closed bottom. The top cover 150 covers the opening of the box body 140 and cooperates with the box body 140 to form a dust collecting chamber 100a. The box body 140 can be connected to the base 160 by welding, screwing, etc. The top cover 150 is detachably connected to the box body 140. As an example, the top cover 150 is snap-connected to the box body 140. In order to prevent the top cover 150 from falling off when the vacuum cleaner 10 is lifted and moved, a hook is also used to connect the top cover 150 to the box body 140.
[0044] In one embodiment, if Figure 1 As shown, the bottom of the box body 100 (i.e., the base 160) is provided with a plurality of running wheels 110. The vacuum cleaner 10 can be moved by the running wheels 110, so that the vacuum cleaner 10 can be quickly moved to a designated position when in use.
[0045] Regarding the number of the running wheels 110, the present application does not impose any specific restrictions, as long as the vacuum cleaner 10 can be moved in different directions. For example, three running wheels 110 are provided along the circumference of the box body 100, or as Figure 1 As shown, two wheels are provided on each of the front and rear sides of the box body 100. Among them, all the running wheels 110 are universal wheels. In this case, the diameters of the running wheels 110 are the same; or, a part of the running wheels 110 can rotate left and right for turning, and the other part is used for moving forward and backward. For example, the running wheels 110 on the front side are used for turning, and the running wheels 110 on the rear side are used for moving forward and backward. In this case, the diameter of the running wheels 110 on the front side can be smaller than the diameter of the running wheels 110 on the rear side. It should be noted that the directions "front", "rear", "left" and "right" in the whole text are represented by Figure 1 The ones shown shall prevail.
[0046] Alternatively, as Figure 1 As shown, a first handle 120 is provided on the side of the housing 100. The operator can grasp the first handle 120 to push or pull the vacuum cleaner 10, thereby facilitating movement of the vacuum cleaner 10. Optionally, the first handle 120 is a push-pull handle. Optionally, the first handle 120 can extend from the bottom of the housing body 140 to the top of the housing body 140.
[0047] Alternatively, as Figure 1As shown, the top of the housing 100 (i.e., the top cover 150) is provided with a second handle 130. The operator can grasp the second handle 130 to lift the vacuum cleaner 10, making it easier to transport. Optionally, the second handle 130 is a lifting handle, rotatably connected to the top cover 150. When the vacuum cleaner 10 needs to be transported, the second handle 130 can be first raised from the top cover 150 to facilitate gripping. When the vacuum cleaner 10 is no longer needed for transport, the second handle 130 can be placed flat on the top cover 150.
[0048] The power unit 200 is located within the dust collection chamber 100a and mounted on the top cover 150 of the housing 100. In vacuuming mode, the power unit draws foreign matter from outside the housing 100 into the dust collection chamber 100a. When the power unit 200 is operating, negative pressure is generated in the dust collection chamber 100a, allowing foreign matter such as powder from the external environment to enter the dust collection chamber 100a through the air inlet of the housing 100, along with the air.
[0049] The first filter element 300 is disposed in the dust collecting chamber 100a and is used to prevent foreign matter from entering the power element 200. In the self-cleaning mode, the power element 200 can vibrate the first filter element 300 to shake foreign matter off the first filter element 300 and into the dust collecting chamber 100a. When air from the external environment, mixed with foreign matter such as powder, enters the dust collecting chamber 100a of the housing 100, the air enters the power element 200 and then flows out of the housing 100 through the exhaust port of the housing 100. In order to prevent foreign matter such as powder from entering the power element 200 with the air and damaging the power element 200, the present application provides a first filter element 300 on the power element 200, which can be used to prevent foreign matter such as powder from entering the power element 200. When it is necessary to clean dust and other foreign matter in the vacuum cleaner 10, the working mode of the vacuum cleaner 10 can be adjusted to the self-cleaning mode, and the power component 200 will vibrate the first filter element 300, so that the foreign matter on the first filter element 300 can be shaken off into the dust collecting chamber 100a, and the operator does not need to open the top cover 150 of the box body 100 to take out the first filter element 300 to clean the first filter element 300.
[0050] The dust exhaust pipe 400 is disposed on the housing 100 and can be stored in the dust collecting chamber 100a or pulled out of the housing 100 (i.e., the dust exhaust pipe 400 extends from the sewage outlet into or out of the dust collecting chamber 100a), so that foreign matter in the dust collecting chamber 100a can be discharged from the dust exhaust pipe 400 by gravity. When it is necessary to clean dust and other foreign matter from the vacuum cleaner 10, the dust exhaust pipe 400 can be first pulled out of the housing 100 and tilted. The foreign matter in the dust collecting chamber 100a is then discharged from the dust exhaust pipe 400 by gravity, and the dust and other foreign matter can be discharged to a target location for subsequent processing, eliminating the need for an operator to clean the dust and other foreign matter in the dust collecting chamber 100a. When the vacuum cleaner 10 is in the vacuuming mode or the non-working mode, the dust exhaust pipe 400 is stored in the dust collecting chamber 100a to prevent the dust exhaust pipe 400 from interfering with the vacuuming of the vacuum cleaner 10, thereby reducing the space occupied by the entire vacuum cleaner 10 and reducing the chance of the dust exhaust pipe 400 being damaged.
[0051] Optionally, the dust exhaust pipe 400 can be a hose, such as a corrugated tube made of plastic. The dust exhaust pipe 400 can be deformed for easy storage and can be tilted after being pulled outside the box 100, thereby ensuring that foreign matter in the dust collection chamber 100a can be discharged to the target location by its own gravity.
[0052] It can be seen that the vacuum cleaner 10 of the present application, through the cooperation of the power member 200 and the dust exhaust pipe 400, when it is necessary to clean the dust, dust and other foreign matter in the vacuum cleaner 10, the power member 200 can make the first filter element 300 vibrate, thereby shaking the foreign matter on the first filter element 300 off into the dust collecting chamber 100a, and the dust exhaust pipe 400 is pulled to the outside of the box body 100, and the dust, dust and other foreign matter in the dust collecting chamber 100a is discharged from the dust exhaust pipe 400 by its own gravity. The entire cleaning process is seamless. The operator is required to clean the first filter element 300 and the dust collecting chamber 100a of the box body 100, which can reduce the difficulty of cleaning and prevent the operator from inhaling dust again, thereby ensuring the health of the operator; and when the vacuum cleaner 10 is in the vacuuming mode or the non-working mode, the dust exhaust pipe 400 can be stored in the dust collecting chamber 100a to prevent the dust exhaust pipe 400 from interfering with the dust collection of the vacuum cleaner 10, and can also reduce the space occupied by the entire vacuum cleaner 10 and reduce the chance of the dust exhaust pipe 400 being damaged.
[0053] In some embodiments of the present application, the sewage outlet is arranged on the side of the box body 100, such as Figure 2 As shown, the dust exhaust pipe 400 is arranged on the side of the box body 100. The sewage outlet is arranged on the side of the box body 100, rather than the bottom, so that after the dust exhaust pipe 400 is pulled out of the dust collecting chamber 100a, there is sufficient space to droop downward, so that foreign matter in the dust collecting chamber 100a can be discharged along the dust exhaust pipe 400 by its own gravity.
[0054] Optionally, the distance from the sewage outlet to the bottom of the box 100 is 15 cm to 25 cm (for example, 15 cm, 17 cm, 19 cm, 21 cm, 23 cm, 25 cm, etc.).
[0055] Continue to see Figure 2 In one embodiment, the lower end of the dust collecting chamber 100a is an inclined tapered structure. The diameter of the dust collecting chamber 100a with a tapered structure gradually decreases in the direction close to the sewage outlet, which can guide the flow of foreign matter such as powder, facilitate the rapid flow of foreign matter such as powder to the bottom of the dust collecting chamber 100a, and thus facilitate the discharge of foreign matter such as dust from the sewage outlet of the box body 100. Among them, the tapered structure is arranged at an angle so that its bottom is connected to the sewage outlet. It should be noted that when the lower end of the dust collecting chamber 100a is arranged at an angle, there is an angle between the axis of the lower end of the dust collecting chamber 100a and the axis of the box body 100.
[0056] Optionally, the lower end of the dust collecting chamber 100a is in an inclined frustum structure.
[0057] like Figure 2 As shown, in some embodiments of the present application, the first filter element 300 includes a filter cover, which is connected to the housing 100 and covers the exterior of the power element 200. The filter cover can provide all-round protection for the power element 200, preventing dust and other foreign matter from flowing into the power element 200 through other non-airflow gaps in the power element 200. In the self-cleaning mode, the first power element 200 can transmit the vibrations it generates to the top cover 150 of the housing 100, and then transmit them to the filter cover through the top cover 150 of the housing 100.
[0058] Of course, in some other embodiments, the first filter element 300 may also be directly mounted on the power element 200. Thus, in the self-cleaning mode, the first power element 200 may directly transmit the vibration generated by itself to the first filter element 300.
[0059] like Figure 2As shown, in some embodiments, the power element 200 includes a vacuum motor 210 and a magnetorheological damper 220. The vacuum motor 210 is connected to the housing 100 and has an adjustable rotation direction. The vacuum motor 210 has an air intake channel and an exhaust channel connected to an exhaust port. The first filter element 300 is provided at least in correspondence with the air intake channel. The magnetorheological damper 220 is provided on the vacuum motor 210 and has an adjustable coil current to adjust the vibration amplitude of the vacuum motor 210. Optionally, the magnetorheological damper 220 may include a cylinder, an excitation coil, magnetorheological fluid, and a piston cylinder. The excitation coil is fixed to the piston cylinder, which is internally mounted in the cylinder body, and the magnetorheological fluid fills the cavity between the cylinder body and the piston cylinder. In the dust suction mode, the vacuum motor 210 is rotated forward to suck foreign matter from the external environment into the dust collecting chamber 100a. At this time, the current of the excitation coil of the magnetorheological damper 220 is set to a smaller value. The magnetorheological fluid is in a fluid state, which can slow down the vibration of the vacuum motor 210 and achieve a shock-absorbing effect. In the self-cleaning mode, the vacuum motor 210 is rotated in the reverse direction. At this time, the current of the excitation coil of the magnetorheological damper 220 is set to a larger value. The magnetorheological fluid is magnetized and exhibits a solid or quasi-solid state. The vibration of the vacuum motor 210 is transmitted to the first filter element 300 through the magnetorheological damper 220 and the top cover 150 of the box body 100 in turn. The foreign matter falls into the dust collecting chamber 100a due to the high-frequency vibration of the first filter element 300.
[0060] Optionally, a plurality of magnetorheological dampers 220 are evenly arranged along the circumference of the vacuum motor 210 , for example, 2, 3, 4 or more.
[0061] Optionally, the vacuum cleaner 10 further includes a power supply module (not shown in the drawings), which is disposed on the housing 100 and is used to supply power to the vacuum motor 210 and the magnetorheological damper 220 .
[0062] Optionally, the exhaust port is a mesh exhaust port, wherein the exhaust port is provided with a second filter (not shown in the drawings), which can prevent foreign matter in the dust collecting chamber 100a from being discharged with the exhaust port gas or external impurities from entering the vacuum motor 210.
[0063] Furthermore, in one embodiment, if Figure 1 As shown, the vacuum cleaner 10 also includes a control module (not shown) and a mode adjustment button 500 disposed on the housing 100. The control module is configured to adjust the rotation direction of the vacuum motor 210 and the coil current supplied by the power supply module to the magnetorheological damper 220 when the mode adjustment button 500 detects a press. The operator can adjust the operating mode of the vacuum cleaner 10 by pressing the mode adjustment button 500 as needed.
[0064] Alternatively, as Figure 1As shown, two mode adjustment buttons 500 are provided: one for vacuuming and the other for self-cleaning. When the vacuuming button detects a press, it transmits a vacuuming command to the control module. Based on the vacuuming command, the control module rotates the vacuum motor 210 forward and reduces the coil current of the magnetorheological damper 220. When the self-cleaning button detects a press, it transmits a cleaning command to the control module. Based on the cleaning command, the control module rotates the vacuum motor 210 in the reverse direction and increases the coil current of the magnetorheological damper 220.
[0065] Of course, in some other embodiments, the mode adjustment button 500 may be set to one. By pressing the mode adjustment button 500 multiple times, the mode adjustment button 500 alternately transmits the vacuuming instruction and the cleaning instruction to the control module.
[0066] like Figure 3 As shown, in some embodiments of the present application, the dust exhaust pipe 400 has a first end and a second end opposite each other, with the first end located within the dust collection chamber 100a and the second end located outside the housing 100. A first stopper 410 is provided on the outer circumference or end surface of the first end. When the dust exhaust pipe 400 is pulled outside the housing 100, the first stopper 410 can abut against the inner wall of the dust collection chamber 100a. The provision of the first stopper 410 prevents the dust exhaust pipe 400 from being completely pulled outside the housing 100, ensuring normal dust exhaust and quick storage of the vacuum cleaner 10.
[0067] Optionally, the first stopping portion 410 may be provided in a circle along the circumference of the dust exhaust pipe 400 or a plurality of first stopping portions 410 may be provided at intervals.
[0068] Similarly, a second stopper 420 is provided on the outer peripheral surface or end surface of the second end. When the dust exhaust pipe 400 is stored in the dust collecting chamber 100a, the second stopper 420 can abut against the outer wall of the housing 100. By providing the second stopper 420, the dust exhaust pipe 400 can be prevented from being completely stored in the integrated chamber, ensuring the normal drawing and pulling of the vacuum cleaner 10.
[0069] Optionally, the second stopping portion 420 may be provided in a circle along the circumference of the dust exhaust pipe 400 or a plurality of second stopping portions 420 may be provided at intervals.
[0070] like Figure 4 As shown, in some embodiments of the present application, the vacuum cleaner 10 further includes a sealing cap 600, which is detachably mounted on the housing 100 and capable of sealing the second end of the dust exhaust pipe 400. When the dust exhaust pipe 400 is housed in the dust collecting chamber 100a, the sealing cap 600 can be used to seal the second end of the dust exhaust pipe 400, thereby preventing foreign matter in the collecting chamber from flowing out through the second end of the dust exhaust pipe 400.
[0071] Alternatively, as Figure 3As shown, the outer wall of the housing 100 is provided with a groove, and the sealing cover 600 can be screwed onto the inner wall of the groove and press the second stopper 420 to the bottom of the groove. When the dust exhaust pipe 400 is stored in the dust collection chamber 100a, the sealing cover 600 is installed in the groove to block the second end of the dust exhaust pipe 400. When dust is required, the sealing cover 600 is opened and the dust exhaust pipe 400 is pulled out.
[0072] like Figure 1 As shown, in some embodiments of the present application, the vacuum cleaner 10 further includes a vacuum tube 700, which is disposed on the housing 100 and communicates with the dust collection chamber 100a. A detachable suction head 710 is disposed at one end of the vacuum tube 700 away from the dust collection chamber 100a. By cooperating with the suction tube 700 and the suction head 710, foreign matter in any area can be cleaned.
[0073] Optionally, the dust suction pipe 700 is a dust suction hose.
[0074] Alternatively, as Figure 1 As shown, a plurality of suction head receiving grooves 100b of different sizes are provided on the outer wall of the box 100. A plurality of different types of suction heads 710 can be placed on the box 100 in advance. When vacuuming, various types of suction heads 710 can be replaced at will to facilitate the suction of dust in various gaps.
[0075] The technical features of the above-mentioned embodiments can be combined arbitrarily.
