Description

Technical Field

[0001] The utility model relates to the field of vacuum cleaners, in particular to a pulse dust shaking vacuum cleaner. Background Art

[0002] A vacuum cleaner is a commonly used household cleaning device at present. A vacuum cleaner capable of relieving pressure and shaking dust is disclosed in the patent publication document CN216907786U. In this type of vacuum cleaner, when the first filter (the reference numeral in the document is 700) is covered with dust and affects further dust suction, this type of vacuum cleaner actively relieves pressure. Through pressure relief, the dust outside the first filter falls under the action of its own gravity. However, this type of vacuum cleaner relies on pressure relief and then allows the dust to fall by its own gravity, so the dust removal effect on the first filter is poor. Content of the Utility Model

[0003] In view of the above problems, the utility model provides a pulse dust shaking vacuum cleaner. By forming a first cavity and a second cavity on both sides of the HEPA respectively, and using an electromagnetic iron component to control the opening and closing of the air path between the first cavity and the second cavity. When the HEPA is blocked by dust and cannot continue the dust suction operation, the electromagnetic iron component can be opened to block the back blowing channel, thereby forming a reverse pulse air flow, which can blow off the dust attached to the HEPA.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A pulse dust shaking vacuum cleaner includes a bottom shell, a shell cover, a HEPA (i.e., a high-efficiency air filter), and a motor. The shell cover and the bottom shell are combined to form a machine shell. The HEPA is arranged inside the machine shell, and the motor is arranged inside the machine shell. It also includes a partition board, a mounting plate, and an electromagnetic iron component. The partition board and the mounting plate are both arranged inside the machine shell. A first cavity is formed between the partition board and the HEPA. A second cavity is formed among the HEPA, the bottom shell, and the mounting plate. A support plate is arranged inside the shell cover or the bottom shell. A third cavity is formed between the support plate and the mounting plate. A back blowing channel is arranged on the partition board. The electromagnetic iron component is arranged on the partition board. The electromagnetic iron component is used to block the back blowing channel. The first cavity and the second cavity are respectively located on both sides of the HEPA.

[0006] In this kind of pulse dust shaking vacuum cleaner, during the dust suction operation, the motor starts to run, and the motor starts to perform a negative pressure pumping operation on the second cavity and the third cavity. The electromagnetic iron attracting component is in a state of blocking the back blowing channel. Air containing a large amount of dust enters the second cavity, and then through the dust filtering function of the HEPA, the dust is intercepted and attached to the HEPA. Then, the clean air without dust enters the third cavity and is discharged into the environment. Since the first cavity and the second cavity are located on both sides of the HEPA respectively, during the dust suction operation, dust will continuously accumulate on one side of the HEPA in the second cavity. And during the process of the dust continuously attaching to the HEPA, the motor will no longer be able to further pump the air flow from the second cavity to the third cavity. At this time, it can be considered that the HEPA is blocked.

[0007] In order to clean the HEPA blocked by dust, at this time, the electromagnetic iron attracting component starts to run, and the electromagnetic iron attracting component no longer blocks the back blowing channel, so that an air path is formed among the first cavity, the second cavity and the third cavity. In this air path, the clean air in the environment enters the first cavity, the clean air in the first cavity flows to the second cavity, and the clean air in the first cavity starts to perform pulse back blowing on the HEPA. The back blowing air flow can blow off the dust attached to the HEPA. When the dust attached to the HEPA is blown off by the pulse back blowing, the HEPA is no longer blocked by dust. At this time, the electromagnetic iron attracting component can be made to block again. At this time, the air flow channel becomes the second cavity flowing to the third cavity again, and the dust-containing air still continuously enters the second cavity, and the HEPA still plays a dust filtering role. After a period of time, the HEPA will still be completely blocked by dust. At this time, the electromagnetic iron attracting component needs to be turned on again, so that the electromagnetic iron attracting component no longer blocks the back blowing channel, and the dust attached to the HEPA is blown off again until the entire dust suction and cleaning operation is completed.

[0008] To sum up, in this kind of pulse dust shaking vacuum cleaner, when the HEPA is blocked by dust and the dust suction operation cannot continue, the blocking of the back blowing channel can be removed by turning on the electromagnetic iron attracting component to form a reverse pulse air flow, and this reverse pulse air flow can blow off the dust attached to the HEPA.

[0009] Specifically, in this kind of pulse dust shaking vacuum cleaner, in order to coordinately control the electromagnetic iron attracting component and the motor, a control circuit board is arranged in the shell cover. The control circuit board is electrically connected to the electromagnetic iron attracting component and the motor, and the control button on the control circuit board is located outside the shell cover.

[0010] Specifically, in this kind of pulse dust shaking vacuum cleaner, an air intake grille is arranged on the shell cover. When performing pulse back blowing on the HEPA, the air in the environment enters the first cavity through the air intake grille, and then blows to the second cavity through the HEPA.

[0011] Optionally, it further includes a dust inlet pipe, and the dust inlet pipe is arranged on the bottom shell.

[0014] Specifically, the gas in the third cavity is discharged into the environment through the exhaust grille.

[0015] Optionally, it further includes a mounting cover. The mounting cover is arranged on the bottom shell or the shell cover. The motor is arranged in the mounting cover, and wind covers are arranged on both sides of the mounting cover. The wind covers are provided with air duct grilles.

[0016] Specifically, the function of the wind cover is to dissipate heat from the motor in the mounting cover, and the function of the air duct grille is to prevent foreign objects in the environment from entering the wind cover. Specifically, the air flow in the environment enters the wind cover through the air duct grille to dissipate heat from the running motor.

[0017] Specifically, the support plate is arranged between the bottom shell and the shell cover, the mounting cover is fixed on the support plate, and the motor is arranged in the mounting cover.

[0018] Optionally, it further includes a suspension bracket. The suspension bracket is arranged on the partition board, and the electromagnetic suction iron assembly is arranged on the suspension bracket.

[0019] Using a suspension bracket to install the electromagnetic suction iron assembly is to ensure the stable operation of the electromagnetic suction iron assembly.

[0020] Optionally, it further includes support feet. The support feet are arranged in the bottom shell and are in contact with the support plate.

[0021] The function of the support feet is to support the support plate, making the various components installed on the support plate more stable.

[0022] Optionally, the bottom shell is provided with rollers and universal wheels, and both the rollers and the universal wheels are located outside the bottom shell.

[0023] The function of setting the universal wheels and the rollers is to facilitate the movement of the entire vacuum cleaner.

[0024] Optionally, the shell cover is provided with a handle, and the handle is located outside the shell cover.

[0025] Specifically, both ends of the handle are rotatably matched with the shell cover. The function of the handle is to facilitate the user to lift and place the entire vacuum cleaner.

[0026] Optionally, it further includes a pull rod, and the pull rod is rotatably matched with the shell cover.

[0027] A socket is rotatably arranged on the outer wall of the specific shell cover, and there are two sockets, which are respectively located at both ends of the shell cover. The pull rod is a flat-bottom U-shaped pull rod, and both ends of the pull rod are respectively inserted and fixed in the two sockets.

[0028] The function of the pull rod is to facilitate pulling the whole vacuum cleaner to move.

[0029] Optionally, a hanging ring is rotatably arranged on the shell cover.

[0030] The beneficial effect of the present utility model is that when the HEPA is blocked by dust and cannot continue the dust suction operation, the plugging of the reverse blowing channel can be removed by opening the electromagnetic iron component to form a reverse pulse air flow, and the reverse pulse air flow can blow off the dust attached to the HEPA.

[0038] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific embodiments of the present utility model will be given with reference to the accompanying drawings.

[0039] In the following description, many specific details are set forth to facilitate a full understanding of the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0040] As shown in the attached Figure 1 , attached Figure 2 , attached Figure 3 and attached Figure 4 , a pulse dust-shaking vacuum cleaner includes a bottom shell 6, a shell cover 1, a HEPA 22 (i.e., a high-efficiency air filter), and a motor 17. The shell cover 1 and the bottom shell 6 are combined to form a machine shell. The HEPA 22 is disposed inside the machine shell, and the motor 17 is disposed inside the machine shell. It further includes a partition 18, a mounting plate 21, and an electromagnetic iron component 19. Both the partition 18 and the mounting plate 21 are disposed inside the machine shell. A first cavity 2301 is formed between the partition 18 and the HEPA 22. A second cavity 2302 is formed among the HEPA 22, the bottom shell 6, and the mounting plate 21. A support plate 20 is disposed inside the shell cover 1 or the bottom shell 6. A third cavity 2303 is formed between the support plate 20 and the mounting plate 21. An air back-blowing channel is provided on the partition 18. The electromagnetic iron component is disposed on the partition 18 and is used to block the air back-blowing channel. The first cavity 2301 and the second cavity 2302 are respectively located on both sides of the HEPA 22.

[0041] In this pulse dust-shaking vacuum cleaner, during the dust suction operation, the motor 17 starts to operate. The motor 17 starts to perform a negative pressure pumping operation on the second cavity 2302 and the third cavity 2303. The electromagnetic iron component is in a state of blocking the air back-blowing channel. Air containing a large amount of dust enters the second cavity 2302, and then through the dust filtering effect of the HEPA 22, the dust is intercepted and attached to the HEPA 22 (at this time, the schematic diagram of the air flow direction is as shown in the attached Figure 4 ), and then the clean air without dust enters the third cavity 2303 and is then discharged into the environment. Since the first cavity 2301 and the second cavity 2302 are respectively located on both sides of the HEPA 22, during the dust suction operation, dust will continuously accumulate on one side of the HEPA 22 located in the second cavity 2302. And during the process of dust continuously attaching to the HEPA 22, the motor 17 will no longer be able to further pump the air flow from the second cavity 2302 to the third cavity 2303 (at this time, the air flow direction is as shown in the attached Figure 5 ), and at this time, it can be considered that the HEPA 22 is blocked.

[0042] To clean the HEPA22 blocked by dust, the electromagnetic suction magnet assembly 19 starts to operate at this time. The electromagnetic suction magnet assembly 19 no longer blocks the backflush channel, enabling an air path to form among the first cavity 2301, the second cavity 2302, and the third cavity 2303. In this air path, clean air in the environment enters the first cavity 2301. The clean air in the first cavity 2301 flows towards the second cavity 2302, and the clean air in the first cavity 2301 starts to perform pulse backflushing on the HEPA22. The backflushing air flow can blow off the dust attached to the HEPA22. When the dust attached to the HEPA22 is blown off by pulse backflushing, the HEPA22 is no longer blocked by dust. At this time, the electromagnetic suction magnet assembly 19 can be re-blocked. At this time, the air flow channel becomes the second cavity 2302 flowing towards the third cavity 2303 again. And the dusty air still continuously enters the second cavity 2302, and the HEPA22 still plays the role of filtering dust. After a period of time, the HEPA22 will still be completely blocked by dust. At this time, the electromagnetic suction magnet assembly 19 needs to be turned on again, so that the electromagnetic suction magnet assembly 19 no longer blocks the backflush channel, and the dust attached to the HEPA22 is blown off again until the entire dust suction and cleaning operation is completed.

[0043] In summary, in this pulse dust shaking vacuum cleaner, when the HEPA22 is blocked by dust and cannot continue the dust suction operation, a reverse pulse air flow can be formed by opening the block of the electromagnetic suction magnet assembly 19 on the backflush channel, and this reverse pulse air flow can blow off the dust attached to the HEPA22.

[0044] Specifically, in this pulse dust shaking vacuum cleaner, to coordinately control the electromagnetic suction magnet assembly 19 and the motor 17, a control circuit board 14 is arranged inside the housing cover 1.

[0045] Specifically, in this pulse dust shaking vacuum cleaner, an air intake grille 9 is arranged on the housing cover 1.

Wind covers 25 are disposed on both sides of the mounting cover 15, and air duct grilles 4 are provided on the wind covers 25.

[0051] Specifically, the function of the wind cover is to dissipate heat from the motor 17 inside the mounting cover 15, while the function of the air duct grille 4 is to prevent foreign objects in the environment from entering the wind cover 25. Specifically, the airflow in the environment enters the wind cover through the air duct grille 4 to dissipate heat from the running motor 17.

[0052] Specifically, referring to what is shown in attached Figure 1 the air duct grille 4 is stuck between the bottom shell 6 and the shell cover.
