Description

Technical Field

[0001] The utility model relates to the technical field of cleaning electrical equipment, in particular to a filter screen disassembly auxiliary device for a vacuum cleaner. Background Art

[0002] The vacuum cleaner filter is an important purification component in the vacuum cleaner, which is used to filter dust, dirt and other impurities in the air to keep the air clean. At present, most vacuum cleaners on the market are equipped with a dust filter, and usually a filter is placed outside the dust filter to further filter the dust particles sucked into the dust filter to achieve efficient dust particle purification effect; the filter needs to be disassembled and cleaned after a period of use to ensure the dust filtering performance of the filter, but the vacuum cleaners on the market currently usually need to be manually disassembled for the filter, and it is difficult to disassemble the filter for some vacuum cleaners with complex structures, resulting in a significant reduction in the disassembly and cleaning rate of the vacuum cleaner, which is time-consuming and labor-intensive. At the same time, improper disassembly can easily cause damage to the vacuum cleaner filter structure, increase equipment maintenance costs, and have poor economic benefits. Utility Model Content

[0003] The utility model overcomes the shortcomings of the prior art and provides a filter screen disassembly auxiliary device for a vacuum cleaner.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is:

[0005] The utility model provides a filter screen disassembly auxiliary device for a vacuum cleaner:

[0006] The filter disassembly auxiliary device includes a disassembly auxiliary mechanism and a filter module. The disassembly auxiliary mechanism includes a rotating outer ring. A plurality of L-shaped arc guide grooves are arranged above the rotating outer ring. The L-shaped arc guide grooves are connected to the circular guide rails. The circular guide rails are arranged on the side of the positioning cover. The positioning cover is provided with a plurality of arc-shaped limiting guide rails. A guide rod is connected to each of the arc-shaped limiting guide rails. One end of the guide rod is welded to the top of the retractable plate. A baffle is arranged on the other end of the guide rod.

[0007] Furthermore, in a preferred embodiment of the utility model, a through hole is opened in the middle of the positioning cover, and the through hole is used to penetrate and be fixed on the dust collecting filter element, and an anti-slip gasket is provided on the inner wall of the through hole.

[0008] Furthermore, in a preferred embodiment of the present invention, a plurality of T-shaped grooves are provided on the rotating outer ring.

[0009] Furthermore, in a preferred embodiment of the present invention, a retractable plate is correspondingly installed in each of the T-shaped slide grooves.

[0010] Furthermore, in a preferred embodiment of the present invention, a permanent magnet is fixed to the bottom of the shrinkage plate.

[0011] Furthermore, in a preferred embodiment of the present invention, a plurality of external teeth are provided on the side surface of one of the L-shaped arc guide grooves.

[0012] Furthermore, in a preferred embodiment of the present invention, the plurality of external teeth mesh with the teeth on the transmission gear.

[0013] Furthermore, in a preferred embodiment of the present invention, the transmission gear is installed on the output end of the stepper motor.

[0014] Furthermore, in a preferred embodiment of the utility model, the stepper motor is fixed through a rectangular sheet metal, and the bottom of the rectangular sheet metal is welded to a positioning cover.

[0015] Furthermore, in a preferred embodiment of the present invention, the filter screen module comprises a metal iron ring, and a vacuum cleaner filter screen is connected to the bottom of the metal iron ring.

[0016] The beneficial technical effects of the utility model are:

[0017] The stepper motor is controlled to start reverse rotation, so that the transmission gear drives the rotating outer ring to rotate clockwise through the external teeth, thereby driving the guide rod on each retractable plate to slide along the arc-shaped limit guide rail with an inward rotation trend. When the guide rail slides with an inward rotation trend, it can drive each retractable plate to gradually retract toward the inside of the rotating outer ring at the same time. At this time, the permanent magnets at the bottom of the multiple retractable plates are blocked by the rotating outer ring so that the annular magnetic field formed disappears, and the metal iron ring loses the magnetic field adsorption force, thereby enabling the vacuum cleaner filter to completely detach from the disassembly auxiliary mechanism. Similarly, controlling the stepper motor to rotate forward can extend the retractable plate, thereby quickly installing the vacuum cleaner filter, achieving the disassembly auxiliary effect of the vacuum cleaner filter, greatly improving the rate of vacuum cleaner filter disassembly, replacing the traditional manual installation steps, saving time and effort.

[0029] Example

[0030] like Figure 1 As shown, the present application provides a filter removal auxiliary device for a vacuum cleaner.

[0031] like Figure 1 As shown, the filter disassembly auxiliary device includes a disassembly auxiliary mechanism and a filter module, the disassembly auxiliary mechanism includes a rotating outer ring 1, a plurality of L-shaped arc guide grooves 2 are arranged above the rotating outer ring 1, the L-shaped arc guide grooves 2 are connected to the circular guide rails 3, the circular guide rails 3 are arranged on the side of the positioning cover 4, the positioning cover 4 is provided with a plurality of arc-shaped limiting guide rails 5, each of the arc-shaped limiting guide rails 5 is connected with a guide rod 6, one end of the guide rod 6 is welded above the shrinkage plate 7, and a baffle 8 is arranged on the other end of the guide rod 6.

[0032] like Figure 1 , 4 As shown, a through hole is opened in the middle of the positioning cover 4, and the through hole is used to penetrate and be fixed on the dust collecting filter element 9, and an anti-slip gasket is arranged on the inner wall of the through hole.

[0033] It should be noted that the dust filter 17 is a dust collecting component that comes with most vacuum cleaners on the market, and the size of the through hole in the middle of the positioning cover 4 conforms to the diameter size of the dust filter 9 of vacuum cleaners on the market. The anti-slip gasket has a high-strength friction force on the side wall of the dust filter 9, which plays an anti-slip role. Therefore, the positioning cover can be fixed to the dust filter 9 by the friction force generated by the anti-slip gasket on the inner wall of the through hole, so as to achieve the effect of installing and disassembling the auxiliary mechanism on the dust filter 9. Due to the setting of the anti-slip gasket, the disassembly auxiliary mechanism can be arbitrarily disassembled and installed on the dust filter of other vacuum cleaners, which improves the adaptability of the device to any vacuum cleaner and is highly practical.

[0034] It should be noted that, since the positioning cover 4 is fixed on the dust filter element 9, the rotating outer ring 1 is controlled to rotate clockwise, and under the action of the L-shaped arc guide groove 2 and the circular guide rail 3, the rotating outer ring 1 rotates relative to the positioning cover 4, thereby driving the guide rod 6 on each retraction plate 7 to slide along the arc limit guide rail 5. Since one end of each arc limit guide rail 5 is set with an inward rotation tendency, each guide rod 6 gradually moves closer to the center of the positioning cover 4, thereby driving each retraction plate 7 to retract inward at the same time. If the rotating outer ring 1 is controlled to rotate counterclockwise, multiple retraction plates 7 can be extended outward synchronously, thereby realizing the intelligent retraction purpose of the retraction plate 7. The automatic retraction of the retraction plate 7 can provide the vacuum cleaner filter 17 with an auxiliary effect of quick disassembly and installation, so as to improve the rate of disassembly of the vacuum cleaner filter and the ease of operation.

[0035] like Figure 3 As shown, a plurality of T-shaped slots 14 are provided on the rotating outer ring 1 .

[0036] like Figure 3 As shown, a shrinkage plate 7 is correspondingly installed in each of the T-shaped slide grooves 14 .

[0037] like Figure 3 As shown, a permanent magnet 15 is fixed to the bottom of the shrink plate 7 .

[0038] It should be noted that when the rotating outer ring 1 is rotated counterclockwise to make the multiple shrinking plates 7 extend synchronously, the permanent magnets 15 at the bottom of the multiple shrinking plates 7 will generate an annular magnetic field around the rotating outer ring 1. When the metal iron ring 16 on the filter module is close to the permanent magnets 15 at the bottom of the multiple shrinking plates 7, the metal iron ring 16 can be strongly adsorbed, so that the vacuum cleaner filter 17 at the bottom of the metal iron ring 16 is placed on the outside of the dust collecting filter element 9, and the vacuum cleaner filter 17 is quickly installed. When the vacuum cleaner filter 17 needs to be disassembled and cleaned after the vacuum cleaner is used, the rotating outer ring 1 is controlled to rotate clockwise to make the multiple shrinking plates 7 shrink synchronously to the inside of the rotating outer ring 1. At this time, the multiple permanent magnets 15 The annular magnetic field formed by the rotating outer ring 1 disappears, and the metal iron ring 16 loses its magnetic field adsorption force and drives the vacuum cleaner filter 17 to completely detach from the disassembly auxiliary mechanism, thereby achieving the disassembly auxiliary effect of the vacuum cleaner filter 17, greatly improving the disassembly rate of the vacuum cleaner filter 17, replacing the traditional manual installation steps, saving time and effort, and solving the disassembly difficulties and disassembly damage frequency caused by the complex disassembly structure of the traditional filter; and the annular magnetic field formed by the multiple permanent magnets has a strong adsorption performance for the metal iron ring 16, so it is impossible to manually pull and disassemble it and it cannot fall off due to the vibration of the vacuum cleaner operation, preventing the vacuum cleaner filter 17 from accidentally detaching during operation, and it has high practicality and reliability.

[0039] like Figure 2As shown, a plurality of external teeth 10 are arranged on the side surface of one of the L-shaped arc guide grooves 2 .

[0040] like Figure 2 As shown, the plurality of external teeth 10 mesh with the teeth on the transmission gear 11 .

[0041] like Figure 2 As shown, the transmission gear 11 is installed on the output end of the stepping motor 12.

[0042] like Figure 2 As shown, the stepper motor 12 is fixed on the rectangular sheet metal 13 , and the bottom of the rectangular sheet metal 13 is welded to the positioning cover 4 .

[0043] It should be noted that when the vacuum cleaner filter 17 needs to be quickly disassembled, the stepper motor 12 is controlled to start reverse rotation, and the output end of the stepper motor 12 rotates forward to make the transmission gear 11 rotate counterclockwise. At this time, the transmission gear 11 drives the rotating outer ring 1 to rotate clockwise through the external teeth 10, thereby driving the multiple retractable plates 7 to shrink synchronously to the inside of the rotating outer ring 1, which can make the magnetic field of the permanent magnet 15 disappear, and then the metal iron ring 16 on the vacuum cleaner filter 17 can be quickly detached, so as to achieve the automatic disassembly effect of the vacuum cleaner filter 17; when the vacuum cleaner filter 17 needs to be disassembled, the stepper motor 12 is controlled to start reverse rotation, and the output end of the stepper motor 12 rotates forward to make the transmission gear 11 rotate counterclockwise. At this time, the transmission gear 11 drives the rotating outer ring 1 to rotate clockwise through the external teeth 10, thereby driving the multiple retractable plates 7 to shrink synchronously to the inside of the rotating outer ring 1, and then the magnetic field of the permanent magnet 15 can be eliminated, and then the metal iron ring 16 on the vacuum cleaner filter 17 can be quickly detached, so as to achieve the automatic disassembly effect of the vacuum cleaner filter 17; When the vacuum cleaner filter 17 is to be quickly installed, it is only necessary to control the stepper motor 12 to start forward rotation, and similarly drive the rotating outer ring 1 to rotate counterclockwise, so that the multiple retractable plates 7 can drive the permanent magnet 15 to extend synchronously, and then quickly adsorb the metal iron ring 16 on the vacuum cleaner filter 17, thereby realizing the automatic installation process of the vacuum cleaner filter 17. This process replaces the step of manually rotating the rotating outer ring 1, improves the convenience and safety factor of operation, saves time and effort, and makes the quick disassembly and installation of the filter more intelligent and automated according to usage requirements, thereby improving the cleaning quality of the vacuum cleaner.

[0044] like Figure 1 , 4 As shown, the filter screen module includes a metal iron ring 16 , and a vacuum cleaner filter screen 17 is connected to the bottom of the metal iron ring 16 .

[0045] It should be noted that the vacuum cleaner filter 17 is a bag filter, which has excellent filtering, dust particle adsorption and dust prevention effects on dust particles inhaled by the vacuum cleaner, avoiding the phenomenon of large-scale dust particles flying when the vacuum cleaner filter 17 is detached during the disassembly process, preventing dust particles from being inhaled into the operator's body, and ensuring the human health safety factor when disassembling the filter; at the same time, the metal iron ring 16 is coated with an anti-rust coating, and the vacuum cleaner filter 17 and the metal iron ring 16 can be placed in water for cleaning as a whole, avoiding rust on the metal iron ring 16 due to long-term water washing, increasing the service life of the metal iron ring, and reducing damage and replacement frequency.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the utility model.
