[0033] Example one

[0034] Reference Figs. 1-3As shown, a dust cleaning equipment convenient to clean dust, including dust cup 2, dust cup 2, filter element 3 and blowing dust removal mechanism, wherein the main machine 1 is provided with suction assembly, main machine 1 is provided with air outlet and suction port, suction assembly usually includes necessary control panel and suction fan, the suction end of suction fan is communicated with suction port, the exhaust end of suction fan is communicated with air outlet. Dust cup 2 is provided with air inlet, air inlet is provided with air inlet pipe 4, dust cup 2 is connected with main machine 1, dust cup 2 is provided with dust outlet 5. When suction assembly sucks air, negative pressure is formed in dust cup 2, and the dust outside will enter dust cup 2 through air inlet pipe 4 along with gas, and the dust cleaning of external environment is completed. The air inlet can be arranged on the side wall of the dust cup, and the air inlet pipe and the dust cup are vertically distributed, or the air inlet pipe and the dust cup are parallelly distributed. For specific position, it can be determined according to use condition. The filter element is arranged in the dust cup, and the filter element and the suction port of the main machine form a channel. The external dust gas enters the dust cup through the air inlet pipe, flows through the filter element and enters the main machine, and is discharged from the air outlet of the main machine. When the dust gas passes through the filter element, the filter element plays a filtering role, blocks the dust, and the dust is adsorbed on the surface of the filter element, or a part of the dust adheres to the inner wall of the dust cup. The blowing dust removal mechanism is arranged in the channel 7 between the filter element 3 and the suction port of the main machine 1, the blowing dust removal mechanism blows clean air, the clean air blows to the surface of the filter element and the inner wall of the dust cup, and the dust and impurities on the surface of the filter element and the inner wall of the dust cup are blown off and discharged to the dust collecting assembly through the dust outlet, so that the filter element and the dust cup can be cleaned without disassembling the filter element and the dust cup, and the filter element and the dust cup do not need to be frequently disassembled and cleaned.

[0035] In addition, the main machine includes necessary shell, handle, key switch and the like, which are basic devices of the dust collector.

[0036] The blowing dust removal mechanism includes a blowing motor 6, and the blowing motor 6 is provided with an air duct penetrating through both ends of the blowing motor. In order to facilitate the installation of the blowing motor, a support can be arranged at the suction port of the main machine 1, and the blowing motor 6 is connected with the support. Since the blowing motor is directly arranged in the channel between the filter element and the suction port, when the blowing motor blows air, the filter element will be swept first, and the air blows from the inner surface of the filter element. When the air passes through the filter element, the dust adhering to the outer surface of the filter element is blown off. Through the continuous blowing of the blowing motor, the air is continuously blown, and the dust on the inner wall of the dust cup is also blown off, so that the dust cleaning of the filter element and the inner wall of the dust cup is completed. The dust collecting assembly can ensure that the dust is discharged to the designated position without secondary pollution.

[0037] The air inlet area of ​​the dust cup 2 is equipped with a one-way valve that opens from the outside to the inside, ensuring that air can only enter from the outside. When the internal blower motor blows air, the air will not be sent out from the air inlet. At this time, the one-way valve is in the closed state, ensuring that the air blown out by the blower motor is blown towards the inner wall of the dust cup in all directions after passing through the filter element.

[0038] The channel 7 formed between the filter element 3 and the air intake of the main unit 1 is a sealed space, allowing gas to pass only through the filter element 3. During vacuuming, external dust enters the dust cup and can only pass through the filter element 3 into the channel 7, then through the air intake into the main unit 1, and finally exit from the air outlet. During self-cleaning, the air blown by the blower motor can only sweep the inner surface of the filter element and be blown outwards. The sealing structure of the channel can be formed by directly attaching the filter element to the main unit, or by using a connector to connect the filter element and the main unit.

[0039] By setting the channel as a sealed space, the blower motor can effectively clean the filter element by blowing air, and the air is blown more concentratedly onto the surface of the filter element.

[0040] Alternatively: The channel 7 formed between the filter element 3 and the air intake of the main unit 1 has a gap, through which gas passes. This gap can be located in different areas of the channel, allowing gas to pass through both the gap and the filter element. In this structure, due to the gap, a small portion of the air blown by the blower motor will leak out through it. Therefore, the airflow cannot be used to clean the filter element to the maximum extent, but this structure can still achieve the goal of cleaning the filter element.

[0041] In addition, the filter element can be cylindrical, forming an internal cavity to accommodate the blower motor, which also serves as part of the channel. Alternatively, the filter element can be a flat plate structure, directly facing the air inlet, or multiple flat filter elements can be arranged to ensure that the dust entering the dust cup from the air inlet first contacts the filter element, achieving effective filtration and dust separation. Other structural forms are also possible.

[0042] Example 2

[0043] like Figs. 1-3 As shown, the dust cup 2 has a cover plate 8 at its dust emptying port. The cover plate 8 seals the dust cup 2, creating a relatively sealed space inside, allowing dust to remain in the dust cup. After opening the cover plate 8, the dust inside the dust cup can be discharged.

[0044] The cover plate 8 is hingedly connected to the dust cup, and covers the dust outlet of the dust cup when no external force is applied. A spring component can be provided to cooperate with the hinged connection of the cover plate and the dust cup, so that the cover plate 8 automatically returns to its original position. The spring component can be a torsion spring, which is arranged to drive the cover plate to tightly press against the dust outlet when no external force is applied, thereby forming a seal for the dust cup. Of course, to achieve better sealing, a sealing ring can also be provided on the dust outlet to achieve better sealing, thereby preventing dust in the dust cup from leaking out of the assembly gap of the cover plate.

[0045] Of course, the cover plate can also be a buckle structure, i.e. the cover plate is fixed to the dust cup by a buckle structure. When dust needs to be removed, the cover plate can be manually opened to clean the inside of the dust cup.

[0046] Embodiment Three

[0047] The dust collection assembly can be various types of products.

[0048] For example, as shown in Fig. 4 the dust collection assembly is a garbage can 9, a garbage can, an empty box, a paper box, etc. When such a collection device is used, a person holding the vacuum cleaner opens the cover plate of the dust cup, and most of the dust in the dust cup will directly fall into the garbage can. However, the dust adhering to the filter element and the inner wall of the dust cup will not fall off. At this time, the blowing motor is started, which blows the dust adhering to the surface of the filter element, and then the wind continues to blow towards the inner wall of the dust cup, thereby blowing the dust adhering to the inner wall of the dust cup and falling into the garbage can, thereby achieving dust collection.

[0049] With reference to Figs. 5-6 the dust collection assembly is a base station 10 for supporting the main body of the vacuum cleaner. The base station 10 includes a dust storage cavity 11, and the base station 10 is connected to the dust cup 2, with the dust outlet 5 of the dust cup 2 facing the dust storage cavity 11. The blowing dust removal mechanism blows the dust adhering to the surface of the filter element 3 and the inner wall of the dust cup 2 towards the dust storage cavity, and the air inlet pipe is provided with a connection extension component 16. The base station can support the entire vacuum cleaner, and the vacuum cleaner is connected to the dust storage cavity, thereby solving the problem of placing the vacuum cleaner. In addition, when the dust in the dust cup is discharged, the dust is not easy to fly to the outside and directly fall into the dust storage cavity, thereby improving the cleanliness of the surrounding environment. Since the main body of the vacuum cleaner can be placed on the base station, the main body of the vacuum cleaner does not need to be hung or placed by a specific tool, thereby eliminating the need to drill holes in the wall to install a support, and the placement is more convenient.

[0050] The extension component can be a lengthened dusting rake, which is used to suck and clean when the main body of the vacuum cleaner is running. The base station has a certain height, and the dusting rake extends downward to the bottom of the base station. The bottom surface of the base station can be provided with a platform to ensure that the base station can stand stably.

[0051] Of course, after a period of use, more dust will accumulate in the dust storage cavity, and cleaning is needed. To facilitate cleaning, a movable door plate can be provided on the side wall of the dust storage cavity. The movable door plate can be opened to clean the dust storage cavity. Alternatively, a dust storage bag can be provided in the dust storage cavity. When the dust storage bag is full, it can be directly removed. Alternatively, a separate barrel can be directly removed from the dust storage barrel.

[0052] The base station 10 is provided with a top block 12, the dust cup 2 is provided with an avoiding groove 13, the cover plate 8 is provided with an opening block 14 extending into the avoiding groove, when the dust cup 2 is connected with the base station 10, the top block 12 pushes the opening block 14 into the avoiding groove 13 to open the cover plate 8, after the dust cup 2 is inserted into the dust storage cavity 411, the top block 12 pushes the opening block 14 upward to make the cover plate 8 rotate around the hinged mounting to open the cover plate 8, and the dust in the dust cup 2 can fall into the dust storage cavity 11. The hinged assembly structure of the cover plate is provided with a torsional spring or other rebound components. After being separated from the dust storage cavity, the opening block is no longer pressed by the top block. At this time, the cover plate automatically returns to seal the dust outlet of the dust cup.

[0053] In addition, the base station 10 is provided with a positioning column 15, and the main machine 1 is provided with a positioning hole. When the dust cup is connected with the base station, the positioning column is inserted into the positioning hole, which ensures the stability of the main machine and the accuracy of installation.

[0054] In the utility model, the base station is taken as an example for description.

[0055] When air suction and dust removal are performed, the air suction assembly is started to form a vacuum negative pressure environment in the dust cup. External dust gas is sucked into the dust cup through the air inlet pipe, passes through the filter element and then enters the main machine from the air suction port. The filtered gas is discharged from the air outlet. After each cleaning is completed, the dust cup of the dust collector is inserted into the dust storage cavity of the base station, the top block pushes open the cover plate, and the dust in the dust cup falls into the dust storage cavity. The air blowing motor is started, air is blown directly from the inner surface of the filter element, the air passes through the filter element, blows off the dust attached to the surface of the filter element, and then the air continues to blow to the inner wall of the dust cup to blow off the dust on the inner wall of the dust cup. The dust falls into the dust storage cavity, the cleaning of the filter element and the inner wall of the dust cup is completed, the frequency of disassembly of the filter element and the frequency of cleaning of the dust cup are reduced, and the user experience is improved.

[0056] It should be noted that the above is only a preferred embodiment of the utility model, and is not used to limit the utility model. Although the utility model is described in detail with reference to the embodiment, the technical solution recorded in the foregoing embodiment can still be modified or some technical features can be replaced by equivalents for the person skilled in the art. However, any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model should be included in the protection scope of the utility model.
