Description

Technical Field

[0001] The present application relates to the technical field of vacuum cleaners, and in particular to a filtering device for vacuum cleaners that is convenient for replacing filters. Background Art

[0002] The vacuum cleaner can remove dust mainly because it has an electric exhaust fan installed on its head. There is a wind impeller on the rotating shaft of the exhaust fan. When powered on, the exhaust fan will generate high suction and pressure at a certain speed. Under the action of suction and pressure, the air is discharged at high speed.

[0003] According to Chinese patent publication number CN215227213U, a self-cleaning vacuum cleaner filter structure is proposed. The beneficial effects of the utility model are: a dust box, a silent fan, a noise reduction pad and a dustproof net are provided. Since a silent fan is installed in the dust box, a noise reduction pad is glued and connected to the outer middle part of the dust box, and the inner sides of the front lower end and the rear lower end of the dust box are connected to the dustproof net, it is convenient to reduce the noise generated during the operation of the vacuum cleaner and to prevent the vacuum cleaner from dusting when it is not in operation. When the above device is in use, the filter net is fixedly installed. Due to long-term use, the filter net is prone to accumulate too much dust and become blocked. The replacement procedure of the filter net is cumbersome, time-consuming and labor-intensive, and it is not convenient to replace the filter net in time, which affects the normal use of the vacuum cleaner and reduces the practicality of the vacuum cleaner. Therefore, we propose a filtering device for a vacuum cleaner that is easy to replace the filter net to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4In this embodiment, a filtering device for a vacuum cleaner that is easy to replace a filter screen comprises a vacuum cleaner body 1 and a filter screen 10. A connecting mechanism is arranged on the outside of the vacuum cleaner body 1. A baffle 2 is fixedly installed between the inner top wall and the inner bottom wall of the vacuum cleaner body 1. A dust collecting box 3 is fixedly installed on the inner bottom wall of the vacuum cleaner body 1. A dust suction pipe 4 with one end penetrating and extending to the inside thereof is fixedly installed on the left side of the vacuum cleaner body 1. A fixing plate 5 is fixedly installed on the left side of the baffle 2 and the left side wall of the inner cavity of the vacuum cleaner body 1. A dust suction pump 6 is fixedly installed on the right side of the baffle 2. A suction pipe 7 with one end penetrating and extending to the outside of the baffle 2 is fixedly installed on the suction port of the dust suction pump 6. An air outlet pipe 8 is fixedly installed on the air outlet of the dust suction pump 6. The filter screen 10 is movably installed inside the vacuum cleaner body 1 and one end thereof penetrates and extends to the outside thereof.

[0023] Among them, a limiting groove is opened on the top of the fixing plate 5, and the size of the limiting groove is adapted to the size of the filter screen 10, so as to achieve the purpose of being able to clamp the filter screen 10, thereby making the filter screen 10 more stable when in use.

[0024] There are two connecting mechanisms, which are respectively located on the left and right sides of the filter 10, so that the filter 10 can be connected and installed from the left and right sides, thereby making the filter 10 more secure during installation and avoiding shaking inside the vacuum cleaner body 1 and affecting the filtering effect.

[0025] It should be noted that the dust suction pipe 4 is a hose, and a dust suction hood is fixedly installed at the bottom of the dust suction pipe 4, the purpose of which is to facilitate the suction of dust from the dust suction hood into the inside of the dust suction pipe 4, thereby improving the dust suction effect.

[0026] Among them, a guide pipe is fixedly installed between the two fixed plates 5, and one end of the guide pipe passes through and extends to the inside of the dust box 3. Its purpose is to facilitate the dust to flow from the fixed plate 5 into the dust box 3, so that the dust can be centrally processed.

[0027] Specifically, by providing a connecting mechanism, the filter 10 can be disassembled and assembled, so that the filter 10 can be quickly disassembled and replaced after being blocked, so that the vacuum cleaner body 1 can operate normally, saving time and effort, and bringing great convenience to the operator.

[0028] like Figure 1 , Figure 2 and Figure 3As shown, in this embodiment, the connecting mechanism includes an installation box 901 fixedly installed on the top of the vacuum cleaner body 1, a motor 902 is fixedly installed on the rear side wall of the inner cavity of the installation box 901, and a rotating rod 903 is fixedly installed on the output shaft of the motor 902 through a coupling, and a gear 904 is fixedly installed on the front side of the rotating rod 903, and a rack plate 905 is movably installed inside the installation box 901, and the outer surface of the gear 904 is meshed with the left side of the rack plate 905, and a support plate 906 is fixedly installed on the bottom of the rack plate 905, and a disc 907 is rotatably installed on the front side of the support plate 906, and a clamping rod 908 with one end passing through and extending to the outside thereof is movably installed inside the installation box 901, and a push block 909 is fixedly installed on the left side of the clamping rod 908, and a spring 910 is fixedly installed between the right side of the push block 909 and the right side wall of the inner cavity of the installation box 901.

[0029] Among them, there are card slots on the left and right sides of the filter screen 10, and the sizes of the two card rods 908 are respectively adapted to the sizes of the two card slots, so that the filter screen 10 can be fixed and installed from the left and right sides, so that the filter screen 10 will not loosen after installation.

[0030] It should be added that the two motors 902 are controlled by the same controller, so that the two motors 902 can work at the same time, saving resources.

[0031] The electrical components in the present invention are all electrically connected to an external main controller, and the main controller can be a conventional known device for controlling a computer, etc. The circuits and controls involved in the present invention are all prior art and will not be elaborated on here.

[0032] Among them, the push block 909 is a right triangle when viewed from the front, and the outer surface of the disk 907 is squeezed against the hypotenuse of the right triangle, so that the two disks 907 can drive the two push blocks 909 to move at the same time, so that the two push blocks 909 can drive the two clamping rods 908 to clamp the filter screen 10.

[0033] In addition, when the two clamping rods 908 clamp the filter screen 10 at the same time, the two springs 910 are in a compressed state.

[0034] Among them, support rods are fixedly installed at the bottom of the two push blocks 909, and sliding grooves are opened on the inner bottom walls of the two installation boxes 901. The outer surfaces of the two support rods are slidably connected to the inner walls of the two sliding grooves respectively, and their function is to support the two push blocks 909, so that the two push blocks 909 are more stable when moving left and right.

[0035] Specifically, by providing an installation box 901, a motor 902, a rotating rod 903, a gear 904, a rack plate 905, a support plate 906, a disc 907, a clamping rod 908, a push block 909 and a spring 910, the purpose of disassembling and replacing the filter 10 is achieved, so that the filter 10 can be quickly disassembled after being blocked, saving time and effort, thereby improving the practicality of the filtering device for the vacuum cleaner that is easy to replace the filter.

[0036] The working principle of the above embodiment is:

[0037] When the filter 10 needs to be replaced, first, the two motors 902 need to be started at the same time, so that the two motors 902 respectively drive the two rotating rods 903 to rotate toward the opposite side at the same time, and the two rotating rods 903 respectively drive the two gears 904 to rotate toward the opposite side at the same time, so that the two gears 904 respectively drive the two rack plates 905 to move upward at the same time, and the two rack plates 905 respectively drive the two support plates 906 to move upward at the same time, so that the two support plates 906 respectively drive the two discs 907 to move upward at the same time, so that the two discs 907 do not squeeze the two push blocks 909. At this time, the two springs 910 are not compressed, so that the two springs 910 respectively drive the two push blocks 909 to move toward the opposite side at the same time, and the two push blocks 909 respectively drive the two clamping rods 908 to move toward the opposite side at the same time, so that the two clamping rods 908 are respectively moved out of the two clamping grooves at the same time, and then the filter 10 can be pulled out of the vacuum cleaner body 1, and the above operation steps are repeated in reverse to install the replaced filter 10.

[0038] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
