Description

Technical Field

[0001] The embodiments of the utility model relate to the technical field of household cleaning equipment, and in particular to a dust cup assembly self-cleaning system and a vacuum cleaner. Background Art

[0002] In existing products, in order to improve the convenience of cleaning the dust in the dust cup inside the vacuum cleaner, the function of a dust collection station is added to the vacuum cleaner. A dust collection chamber is set in the dust collection station, and the dust in the dust cup can be cleaned by connecting to the dust collection station.

[0003] However, existing solutions all require the dust cup cover assembly to be flipped up, forcing the user to manually open the dust cup cover and then connect it to the dust collection station for self-cleaning. This process is cumbersome, inconvenient, and prone to dust leakage. In addition, the dust cup cover assembly has a redundant structure, is usually large in size, and is expensive to manufacture. Utility Model Content

[0004] The utility model provides a dust cup component self-cleaning system and a dust cleaner with simple structure and easy operation.

[0005] In order to solve the above technical problems, the embodiment of the present invention provides a dust cup assembly self-cleaning system, which is applied to a vacuum cleaner. The dust cup assembly self-cleaning system includes:

[0006] A dust cup assembly, comprising a dust cup, an air duct conversion assembly, and a dust cup cover assembly, wherein the air duct conversion assembly is partially located in the dust cup and partially located in the dust cup cover assembly;

[0007] A dust collecting base station having a connection end connected to the dust cup cover assembly;

[0008] Among them, the dust cup has a dust collecting chamber and a first air duct connected to the dust collecting chamber. When the dust cup assembly is separated from the dust collecting base station, the air duct conversion assembly blocks the first air duct. When the dust cup assembly is connected to the dust collecting base station, the air duct conversion assembly is squeezed and displaced by the connecting end, thereby making the first air duct conductive, so that the dust in the dust collecting chamber can enter the dust collecting base station through the first air duct under the suction of the dust collecting base station.

[0009] In some embodiments, the dust cup has a second air duct that is always in a conducting state, and the second air duct is used to connect with the dust suction channel in the vacuum cleaner. The dust cup also has a filter component, and the filter component is used to filter the airflow introduced by the second air duct, and the filtered dust falls into the dust collecting chamber.

[0010] In some embodiments, when the dust cup assembly is separated from the dust collection base station, the air duct conversion assembly blocks the first air duct and takes over the open end of the second air duct and the dust cup cover assembly. When the dust cup assembly is connected to the dust collection base station, the air duct conversion assembly shifts to connect the first air duct, so that the second air duct, the first air duct and the open end of the dust cup cover assembly are interconnected.

[0011] In some embodiments, the dust cup cover assembly is arranged on the bottom end of the dust cup and passes through the bottom end of the dust cup. The dust cup has an air duct tube for forming a second air duct. The air duct tube is suspended at one end facing the dust cup cover assembly and has a gap with the bottom end of the corresponding dust cup. The area between the cup wall of the dust cup and the tube wall of the air duct tube forms the dust collecting chamber. The gap is connected to the dust collecting chamber and cooperates to form the first air duct.

[0012] In some embodiments, the air duct conversion assembly is movably disposed in the dust cup and dust cup cover assembly to block or open the first air duct by blocking or releasing the gap.

[0013] In some embodiments, the air duct conversion assembly includes a conversion push block, which is annular and movably arranged in the dust cup. When the dust cup assembly is separated from the dust collection base station, the conversion push block abuts against the bottom end of the dust cup to block the gap and thereby block the first air duct.

[0014] In some embodiments, the conversion push block includes a hollow cylindrical body, a circle of protrusions provided at the bottom of the hollow cylindrical body, and a clamping piece provided on the hollow cylindrical body, the protrusion is in contact with the bottom end of the dust cup, the hollow cylindrical body is sleeved on the outside of the suspended end of the air duct pipe, the filter assembly is cylindrical, which is sleeved on the air duct pipe and is located above the conversion push block, and an elastic piece is connected between the filter assembly and the clamping piece of the conversion push block, and the conversion push block has a driving force to move toward the bottom end of the dust cup and resist it based on the elastic force of the elastic piece.

[0015] In some embodiments, the air duct conversion assembly also includes a push rod, which is arranged in the dust cup cover assembly, and one end passes through the dust cup cover assembly and abuts against the conversion push block. When the dust cup assembly is connected to the dust collection base station, the connection end of the dust collection base station extends into the dust cup cover assembly and pushes the push rod, so that the push rod pushes the conversion push block away from the bottom end of the dust cup, thereby opening the first air duct.

[0016] In some embodiments, the push rod has a pushing portion extending out of the dust cup cover assembly, and the dust cup cover assembly is provided with a long hole for the pushing portion to move. The connecting end drives the push rod and the conversion push block to move by pushing the pushing portion.

[0017] Another embodiment of the present invention further provides a vacuum cleaner, comprising a dust cup assembly self-cleaning system as described in any of the embodiments above.

[0018] Based on the disclosure of the above embodiments, it can be known that the beneficial effects of the embodiments of the present invention include improving the structure of the dust cup assembly, using an air duct conversion assembly located in the dust cup and dust cup cover assembly and movable relative to the two to achieve the blocking of the first air duct in the dust cup, and at the same time using the connection between the dust cup assembly and the dust collection base station to drive the air duct conversion assembly to move, so as to conduct the first air duct. The entire process does not require the user to manually perform any operations other than connecting the dust cup assembly to the dust collection base station. The operation is simple and the automatic cleaning effect of the dust cup assembly is fully realized.

[0034] Below, the embodiment of the present utility model is described in detail with reference to the accompanying drawings.

[0035] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, an embodiment of the present invention provides a dust cup assembly self-cleaning system, which is applied to a vacuum cleaner. The dust cup assembly self-cleaning system includes:

[0036] The dust cup assembly 1 includes a dust cup 4, an air duct conversion assembly, and a dust cup cover assembly 11. The air duct conversion assembly is partially located in the dust cup 4 and partially located in the dust cup cover assembly 11.

[0037] The dust collecting base station 2 has a connection end connected to the dust cup cover assembly 11;

[0038] Among them, the dust cup 4 has a dust collecting chamber and a first air duct 3 connected to the dust collecting chamber. When the dust cup assembly 1 is separated from the dust collecting base station 2, the air duct conversion assembly blocks the first air duct 3. When the dust cup assembly 1 is connected to the dust collecting base station 2, the air duct conversion assembly is squeezed and displaced by the connection end, thereby making the first air duct 3 in a conductive state, so that the dust in the dust collecting chamber can enter the dust collecting base station 2 through the first air duct 3 under the suction force of the dust collecting base station 2.

[0039] Based on the above, it can be seen that this embodiment improves the structure of the dust cup assembly 1 and uses an air duct conversion assembly located in the dust cup 4 and the dust cup cover assembly 11 and capable of moving relative to the two to achieve the blocking of the first air duct 3 in the dust cup 4. At the same time, the connection between the dust cup assembly 1 and the dust collection base station 2 is used to drive the air duct conversion assembly to move to conduct the first air duct 3. The entire process does not require the user to manually perform any operations other than connecting the dust cup assembly 1 and the dust collection base station 2. The operation is simple and the automatic cleaning effect of the dust cup assembly 1 is completely achieved. In addition, the overall structure of the self-cleaning system of the dust cup assembly 1 is simple, and only further improvements need to be made to the original structure of the dust cup assembly 1. It is easy to implement and low cost.

[0040] Specifically, the dust cup 4 in this embodiment has a second air duct 5 that is always in a conducting state, and the second air duct 5 is used to communicate with the dust suction channel in the vacuum cleaner.

[0041] The dust cup 4 further includes a filter assembly 6, which is used to filter the airflow introduced into the second air duct 5, and the filtered dust falls into the dust collecting chamber.

[0042] Among them, when the dust cup assembly 1 is separated from the dust collection base station 2, the air duct conversion assembly blocks the first air duct 3 and takes over the open end of the second air duct 5 and the dust cup cover assembly 11. The dust cup cover assembly 11 is hollow inside, with both ends being open ends and interconnected. The open end described in this embodiment can be any end, and is not limited to any specific end. For the convenience of explanation, this embodiment takes the open end as the end where the dust cup cover assembly 11 is connected to the dust cup 4 as an example for subsequent explanation. When the dust cup assembly 1 is connected to the dust collection base station 2, the air duct conversion assembly shifts, and the first air duct 3 is turned on, so that the second air duct 5, the first air duct 3 and the open end of the dust cup cover assembly 11 are interconnected. That is, the second air duct 5 is connected to the first air duct 3, and the two air ducts are simultaneously connected to the open end of the dust cup cover assembly 11.

[0043] Continue to combine Figure 3 and Figure 4As shown, the dust cup cover assembly 11 in this embodiment is provided on the bottom end of the dust cup 4 and passes through the bottom end of the dust cup 4, that is, the bottom of the dust cup 4 is open. The dust cup cover assembly 11 is provided at the bottom end of the dust cup 4, and its open end is correspondingly connected to the opening at the bottom end of the dust cup 4. The dust cup 4 has an air duct tube 7 for forming a second air duct 5. The end of the air duct tube 7 facing the dust cup cover assembly 11 is suspended in the air and has a gap with the bottom end of the corresponding dust cup 4. The area between the cup wall of the dust cup 4 and the tube wall of the air duct tube 7 forms the dust collecting cavity. The gap is connected to the dust collecting cavity and cooperates to form the first air duct 3. That is, the dust collecting cavity and the gap cooperate to form the first air duct 3, and the end of the first air duct 3 is the opening at the bottom of the dust cup 4.

[0044] The air duct conversion assembly is movably arranged in the dust cup 4 and the dust cup cover assembly 11 to achieve blocking or opening of the first air duct 3 by blocking or releasing the gap.

[0045] Specifically, such as Figure 5 As shown, the air duct conversion assembly in this embodiment includes a conversion push block 8, which is annular and movably arranged in the dust cup 4. When the dust cup assembly 1 is separated from the dust collecting base station 2, the conversion push block 8 is abutted against the bottom end of the dust cup 4 to block the gap and thereby block the first air duct 3.

[0046] Continue to combine Figure 5 As shown, the conversion push block 8 comprises a hollow cylindrical body, a raised edge at the bottom of the hollow cylindrical body, and a latch mounted on the hollow cylindrical body. The latch can be an annular protrusion or at least two correspondingly positioned protrusions. The raised edge extends horizontally outward from the bottom of the hollow cylindrical body and abuts against the bottom end of the dust cup 4. The hollow cylindrical body fits over the suspended end of the air duct tube 7. The filter assembly 6 is cylindrical and fits over the air duct tube 7, positioned above the conversion push block 8. A hepa 12 is provided within the dust cup 4 at the top end of the air duct tube 7. An elastic member 9, such as a spring, is connected between the filter assembly 6 and the latch of the conversion push block 8. The spring's ends, respectively, press against the latch and filter assembly 6, maintaining a constant compressed state to provide a constant elastic restoring force. The elastic force of the elastic member 9, i.e., the elastic restoring force, provides the conversion push block 8 with a driving force to move toward and against the bottom end of the dust cup 4. For example, the conversion push block 8 always has the force to move toward the dust cup cover assembly 11 under the action of its own weight and elastic restoring force. Based on this force, the conversion push block 8 can always be driven to abut against the bottom end of the dust cup 4 in the absence of external pushing force, thereby blocking the first air duct 3. At the same time, after being pushed and displaced, the conversion push block 8 can automatically move to the position abutting against the bottom end of the dust cup 4 when the pushing force disappears, thus achieving the effect of automatically blocking the first air duct 3.

[0047] Furthermore, the air duct conversion assembly also includes a push rod 10, which is arranged in the dust cup cover assembly 11, and one end of which passes through the dust cup cover assembly 11 and abuts against the conversion push block 8. When the dust cup assembly 1 is connected to the dust collection base station 2, the connection end of the dust collection base station 2 extends into the dust cup cover assembly 11 and pushes the push rod 10, so that the push rod 10 pushes the conversion push block 8 away from the bottom end of the dust cup 4, thereby conducting the first air duct 3. The push rod 10 has a pushing portion that extends horizontally out of the dust cup cover assembly 11, and the dust cup cover assembly 11 is provided with a long hole for the pushing portion to move. The connecting end drives the push rod 10 and the conversion push block 8 to move by pushing the pushing portion. Of course, the pushing portion can also extend vertically out of the dust cup cover assembly 11. The specific needs depend on the structure of the connecting end, as long as it can achieve pushing the push rod 10.

[0048] The dust collecting base station 2 has a dust collecting bag and a suction motor. When the first air duct 3 is opened, Figure 4 As shown, the dust can flow into the dust cup cover assembly 11 through the first air duct 3 based on the suction of the suction motor, and then flow to the air duct opening of the dust collecting base station 2 and fall into the dust collecting bag. After a period of time, the dust in the dust cup 4 will be emptied. At this time, the automatic cleaning of the dust cup assembly 1 is completed. The user can remove the dust cup assembly 1 and reinstall it on the vacuum cleaner. Since the dust cup assembly 1 is separated from the dust collecting base station 2, the conversion push block 8 is reset and continues to block the first air duct 3. At this time, only the second air duct 5 is active. For details, please refer to Figure 3 shown.

[0049] Another embodiment of the present invention also provides a vacuum cleaner, including a self-cleaning system of the dust cup assembly 1 as described in any of the embodiments above.

The scope of protection of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the spirit and scope of protection of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the scope of protection of the present invention.
