Description

Technical Field

[0001] This utility model belongs to the field of cleaning equipment technology, and specifically provides a vacuum cleaner, a base station, and a cleaning system. Background Technology

[0002] As people's living standards improve, their demand for and requirements of cleaning equipment are also increasing. Vacuum cleaners, as common cleaning tools, play an important role in daily life. In existing cleaning systems, when a certain amount of foreign matter accumulates inside the vacuum cleaner's main unit, it is necessary to expel the foreign matter to ensure the normal operation of the vacuum cleaner.

[0003] Currently, the common method for removing foreign objects involves the user manually opening or closing the bottom cover of the vacuum cleaner unit, which then connects the unit to the base station to expel the object. This method has several inconveniences. First, the user needs to operate it manually. In actual use, after using the vacuum cleaner, the user's hands may be dusty or in a state where it is difficult to operate the vacuum cleaner, making it inconvenient to manually open and close the bottom cover.

[0004] Secondly, to enable manual opening and closing of the bottom cover, a relatively complex mechanical structure is usually required to ensure stable closure and smooth opening. This complex mechanical structure not only increases manufacturing costs but also, due to frequent operation during long-term use, makes the components more prone to wear and malfunction, reducing product reliability and lifespan. Utility Model Content

[0005] One objective of this invention is to solve the problem of inconvenient operation when the vacuum cleaner main unit is connected to the base station to expel foreign objects.

[0006] To achieve the above objectives, this utility model provides a vacuum cleaner, comprising:

[0007] The dust cup has a dust drain at the bottom;

[0008] The bottom cover is rotatably connected to the dust cup and includes a main body and an opening part. The main body is used to open and close the dust discharge port, and the opening part is used to drive the bottom cover to rotate so that the main body opens the dust discharge port.

[0009] A preload is used to keep the bottom cover in the closed position of the dust outlet.

[0010] Optionally, the pivot of the bottom cover is located between the main body and the opening portion, so that when the opening portion is driven toward the dust cup, it forces the main body to open the dust outlet.

[0011] Optionally, the bottom of the dust cup defines a downward-facing clearance cavity, and the opening portion is always located in the clearance cavity.

[0012] Optionally, the bottom cover also includes a connecting portion, one end of which is connected to the main body portion, and the other end of which is connected to the opening portion;

[0013] The main body and the connecting part are V-shaped, and the opening part and the connecting part are V-shaped, so that the opening part is entirely located in the clearance cavity.

[0014] Optionally, the included angle between the main body and the connecting part is selected from any value between 87° and 131°; and / or the included angle between the opening part and the connecting part is selected from any value between 70° and 106°.

[0015] Optionally, the bottom cover also includes reinforcing ribs, which are fixedly connected to the main body and the opening portion or integrally formed therefrom.

[0016] Optionally, the bottom surface of the main body is parallel to the bottom surface of the reinforcing rib.

[0017] Optionally, the angle between the opening portion and the main body portion is selected from any value between 115° and 195°.

[0018] Optionally, the preload element is a torsion spring, which is disposed at the pivot position.

[0019] Optionally, a first magnet is provided on the side of the main body away from the rotating shaft, and a second magnet is provided on the edge of the dust discharge port, configured such that when the main body closes the dust discharge port, the first magnet and the second magnet attract each other.

[0020] This utility model also provides a base station, including:

[0021] Dust collection box, used to store foreign objects;

[0022] A dust collection tube, adapted to any of the vacuum cleaners described above, and capable of being connected to the vacuum cleaner;

[0023] A protrusion is provided on the top of the dust collection pipe, and during the process of the vacuum cleaner connecting with the dust collection pipe, it abuts against the opening part of the bottom cover and forces the bottom cover to rotate towards the base station side to open the dust discharge port, thereby connecting the dust cup and the dust collection box.

[0024] This utility model also provides a cleaning system, including:

[0025] The vacuum cleaner described in any of the above and the base station described above.

[0026] Based on the foregoing description, those skilled in the art will understand that in the aforementioned technical solution of this utility model, the dust outlet is opened by pushing the opening part with external force to drive the bottom cover to rotate, which makes it convenient for users to open the bottom cover to clean foreign objects in the dust cup and avoids foreign objects from soiling the user's hands.

[0027] Furthermore, by defining a downward-facing clearance cavity at the bottom of the dust cup and ensuring that the opening part is always located within the clearance cavity, the opening part has sufficient space to accommodate other components of the dust cup during operation, thus preventing interference with other components of the dust cup and ensuring the smooth operation of the bottom cover rotation opening action. At the same time, it also protects the opening part to a certain extent, making it less susceptible to damage from external collisions.

[0028] Furthermore, by connecting one end of the connecting part to the main body and the other end of the connecting part to the opening part, and by setting the main body and the connecting part to a V-shape, and setting the opening part and the connecting part to a V-shape, the opening part is entirely located in the clearance cavity, making the overall structure more compact; and the V-shaped structure, while ensuring the strength of the bottom cover, also helps to guide the movement of the opening part in the clearance cavity, improving the stability of the bottom cover's movement.

[0029] Furthermore, by fixing the reinforcing ribs to the main body and the opening part separately or making them as a single unit, the overall structural strength of the bottom cover can be enhanced, especially the two key parts of the main body and the opening part. This reduces the possibility of deformation or damage caused by stress during frequent opening and closing, and extends the service life of the bottom cover.

[0030] Furthermore, by setting a first magnet on the side of the main body away from the pivot and a second magnet on the edge of the dust outlet, the stability of the bottom cover in the closed state is improved, preventing foreign objects from spilling out of the dust cup.

[0048] like Figure 1 As shown, the vacuum cleaner 100 generally includes a main unit 101, a connecting rod, and a nozzle.

[0049] like Figure 2 As shown, in some embodiments of this utility model, the main unit 101 includes a dust cup 110, a bottom cover 120, and a pre-tightening member 130.

[0050] The dust cup 110 is a container used by the vacuum cleaner 100 to collect various debris such as dust, hair, and lint. When the vacuum cleaner 100 is working, it uses suction to suck up debris from surfaces such as floors and furniture, which is then stored in the dust cup 110. The bottom of the dust cup 110 has a dust drain port 111, and a bottom cover 120 is rotatably connected to the dust drain port 111. The bottom cover 120 is used to close the dust drain port 111, creating a closed space inside the dust cup 110 to store foreign objects. When the dust cup 110 is full of foreign objects, the bottom cover 120 is opened to allow the foreign objects to be emptied through the dust drain port 111.

[0051] like Figure 3 and Figure 4 As shown, the bottom cover 120 includes a main body 121 and an opening part 122. The main body 121 is used to open and close the dust discharge port 111, and the opening part 122 is used to drive the bottom cover 120 to rotate so that the main body 121 opens the dust discharge port 111.

[0052] In this embodiment, by setting a dust discharge port 111 at the bottom of the dust cup 110, it is not necessary to disassemble the entire dust cup 110 for cleaning. Simply open the dust discharge port 111 to directly discharge the dust and debris inside the dust cup 110, which greatly saves cleaning time and effort and improves cleaning efficiency.

[0053] In this embodiment, the dust cup 110 is also provided with a pre-tightening member 130, which is used to keep the bottom cover 120 in the position of closing the dust discharge port 111.

[0054] like Figure 4 As shown, in some embodiments of this utility model, the pivot 123 of the bottom cover 120 is located between the main body 121 and the opening part 122. The pivot 123 is connected to the dust cup 110 so that when the opening part 122 is driven in a direction close to the dust cup 110, it forces the main body 121 to open the dust discharge port 111.

[0055] Those skilled in the art will understand that when an upward force is applied to the opening part 122, the opening part 122 will rotate upward around the pivot 123, and the main body part 121 will rotate downward around the pivot 123, thereby opening the dust discharge port 111.

[0056] The opening part 122 can be a plate-like structure, so that external force can act on the opening part 122.

[0057] Furthermore, since the bottom cover 120 and the dust cup 110 are movably connected, a pre-tightening member 130 is provided at the position of the pivot 123 to ensure that the bottom cover 120 remains in the closed dust outlet 111 position when not subjected to external force. Specifically, as shown... Figure 4 As shown, the preload 130 can be a torsion spring 140 located at the pivot 123. The torsion spring 140, located at the pivot 123, can provide a stable and appropriate preload force to the bottom cover 120, making the closed state of the bottom cover 120 more reliable. At the same time, when opening, the elastic restoring force of the torsion spring 140 helps the bottom cover 120 to quickly return to its closed position, making operation more convenient.

[0058] like Figure 6 As shown, in some embodiments of this utility model, the bottom of the dust cup 110 defines a downward-facing relief cavity 112, and the opening part 122 is always located in the relief cavity 112, that is, the opening part 122 always moves within the relief cavity 112. The relief cavity 112 provides specific movement space for the opening part 122, so that the opening part 122 has sufficient accommodation space during operation, avoiding interference with other components of the dust cup 110, ensuring the smooth rotation and opening of the bottom cover 120, and at the same time protecting the opening part 122 to a certain extent, making it less susceptible to damage from external collisions.

[0059] like Figure 6 As shown, in some embodiments of this utility model, the dust cup 110 further includes a spout 113 for cooperating with the bottom cover 120 to jointly seal the bottom of the dust cup 110. A dust discharge port 111 is formed in the middle of the spout 113, and a connection position for the bottom cover 120 to be rotatably connected is formed on one side of the spout 113. Furthermore, a clearance cavity 112 is formed on the spout 113.

[0060] like Figure 5 As shown, in some embodiments of this utility model, the bottom cover 120 further includes a connecting portion 124, one end of which is connected to the main body portion 121, and the other end of which is connected to the opening portion 122. The main body portion 121 and the connecting portion 124 form a V-shape, and the opening portion 122 and the connecting portion 124 also form a V-shape, so that the opening portion 122 is entirely located in the clearance cavity 112.

[0061] In this embodiment, this special shape design allows the opening part 122 to be fully located in the avoidance cavity 112, further optimizing the structural layout and making the overall structure more compact. On the other hand, the V-shaped structure, while ensuring the strength of the bottom cover 120, also helps guide the movement of the opening part 122 within the avoidance cavity 112, improving the stability of the bottom cover 120's movement.

[0062] In some embodiments of this utility model, the included angle between the main body 121 and the connecting part 124 is selected from any value between 87° and 131°. For example, the included angle between the main body 121 and the connecting part 124 can be 87°, 100°, and 131°, etc.

[0063] Furthermore, the included angle between the main body 121 and the connecting part 124 is selected from any value between 98° and 120°. For example, the included angle between the main body 121 and the connecting part 124 can be 98°, 110°, and 120°, etc. Within this angle range, a good balance can be achieved between the structural strength of the bottom cover 120, the flexibility of its opening action, and its compatibility with the clearance cavity 112. For example, a suitable included angle can ensure that the bottom cover 120 is subjected to uniform force on each part during opening and closing, and is not easily damaged due to stress concentration.

[0064] In some embodiments of this utility model, the included angle between the opening portion 122 and the connecting portion 124 is selected from any value between 70° and 106°. For example, the included angle between the opening portion 122 and the connecting portion 124 can be 70°, 90°, and 106°, etc.

[0065] Furthermore, the included angle between the opening portion 122 and the connecting portion 124 is selected from any value between 79° and 97°. For example, the included angle between the opening portion 122 and the connecting portion 124 can be 79°, 88°, and 97°, etc.

[0066] like Figure 4 and Figure 6 As shown, in some embodiments of this utility model, the bottom cover 120 further includes a reinforcing rib 125, which is fixedly connected to the main body 121 and the opening part 122 or integrally formed therefrom. The reinforcing rib 125 can enhance the overall structural strength of the bottom cover 120, especially the two key parts of the main body 121 and the opening part 122, reducing the possibility of deformation or damage due to force during frequent opening and closing, and extending the service life of the bottom cover 120.

[0067] In some embodiments of this utility model, the bottom surface of the main body 121 is parallel to the bottom surface of the reinforcing rib 125. This parallel arrangement ensures that the transmission and distribution of force on the bottom cover 120 are consistent each time an external force is applied to open the bottom cover 120. Whether in the daily use of the vacuum cleaner 100 or over a long period of use, the way and extent to which the bottom cover 120 opens remains relatively stable each time it comes into contact with the external drive component. This helps maintain the stability of the docking and bottom cover opening operation between the vacuum cleaner 100 and the base station 200, reduces problems such as poor foreign object discharge and damage to the bottom cover 120 caused by inaccurate bottom cover opening control, and improves the user experience and overall product performance.

[0068] In some embodiments of this utility model, the included angle between the opening portion 122 and the main body portion 121 is selected from any value between 115° and 195°. For example, the included angle between the opening portion 122 and the main body portion 121 can be 115°, 140°, and 195°, etc.

[0069] Furthermore, the angle between the opening portion 122 and the main body portion 121 is selected from any value between 115° and 195°. For example, the angle between the opening portion 122 and the main body portion 121 can be 130°, 150°, and 165°.

[0070] like Figure 3 and Figure 4 As shown, a first magnet 126 is provided on the side of the main body 121 away from the rotating shaft 123, and a second magnet 127 is provided on the edge of the dust discharge port 111. The configuration is such that when the dust discharge port 111 of the main body 121 is closed, the first magnet 126 and the second magnet 127 are attracted together.

[0071] Those skilled in the art will understand that if the bottom cover 120 is held in the closed position solely by the pre-tightening member 130, the closed state of the bottom cover 120 is not stable, and the bottom cover 120 may be opened and foreign objects may spill out if the user accidentally touches it. The arrangement of the first magnet 126 and the second magnet 127 can stably close the bottom cover 120 at the dust discharge port 111, thus avoiding the above situation.

[0072] like Figure 7 and Figure 8 As shown, this utility model also provides a base station 200, which includes a dust collection box 210, a dust collection pipe 220, and a protrusion 230. The dust collection box 210 is used to store foreign objects, and the dust collection pipe 220 is adapted to the aforementioned vacuum cleaner 100 and can be connected to it. The base station 200 has a dust collection function. After the vacuum cleaner 100 completes its cleaning work and returns to the base station 200, the dust collection pipe 220 of the base station 200 connects to the dust outlet 111 of the vacuum cleaner 100, and the dust and debris in the dust cup 110 fall into the dust collection box 210 inside the base station 200.

[0073] Meanwhile, the dust collection pipe 220 enables the vacuum cleaner 100 to connect with the base station 200, ensuring that foreign objects in the dust cup 110 can be smoothly discharged into the dust collection box 210 through the dust collection pipe 220.

[0074] Specifically, the base station 200 is equipped with a fan. The base station 200 uses strong suction to draw dust and debris from the dust cup 110 into the dust collection box 210 of the base station 200, realizing automatic dust collection, avoiding frequent cleaning of the dust cup 110 by the user, reducing contact with dust, and making the cleaning process more hygienic and convenient.

[0075] A protrusion 230 is provided on the top of the dust collection pipe 220. During the docking process between the vacuum cleaner 100 and the dust collection pipe 220, the protrusion 230 abuts against the opening part 122 of the bottom cover 120 and forces the bottom cover 120 to rotate towards the base station 200 to open the dust discharge port 111, thereby connecting the dust cup 110 and the dust collection box 210, enabling the base station 200 to collect foreign objects from the dust cup 110 of the vacuum cleaner 100. Furthermore, the bottom cover 120 can open automatically when the vacuum cleaner 100 docks with the base station 200, without the need for manual operation by the user.

[0076] like Figure 1 As shown, the present invention also provides a cleaning system 001, which includes the vacuum cleaner 100 and the base station 200 described above.

[0077] The following explains the working principle of Cleaning System 001:

[0078] Vacuum cleaner 100 operating phase: The vacuum cleaner 100 includes a main unit 101, a connecting rod, and a suction head. The dust cup 110 in the main unit 101 serves as a container for collecting debris. During operation, suction forces dust, hair, and other debris into the dust cup 110 through the suction head and connecting rod. A dust discharge port 111 is located at the bottom of the dust cup 110, which is closed by a rotatably connected bottom cover 120, forming a closed space for storing foreign objects. The bottom cover 120 includes a main body 121, an opening portion 122, a connecting portion 124, and a reinforcing rib 125. The main body 121 is used to open and close the dust discharge port 111, the opening portion 122 is used to drive the bottom cover 120 to rotate, the connecting portion 124 connects the main body 121 and the opening portion 122, and the reinforcing rib 125 enhances the structural strength of the bottom cover 120.

[0079] Meanwhile, the dust cup 110 is also equipped with a pre-tensioning component 130 (such as a torsion spring 140 at the pivot 123) to keep the bottom cover 120 closed when no external force is applied. Furthermore, the clearance cavity 112 at the bottom of the dust cup 110 provides space for the opening part 122 to avoid interference. The angle design between the main body 121 and the connecting part 124, and between the opening part 122 and the connecting part 124, optimizes the structural layout and operational stability. The parallelism between the bottom surface of the main body 121 and the bottom surface of the reinforcing rib 125 ensures the stability of the bottom cover 120 under force and during opening. First and second magnets 127 are respectively provided along the edges of the main body 121 and the dust outlet 111 to enhance the stability of the bottom cover 120 when closed.

[0080] Dust collection stage of base station 200: Base station 200 is equipped with a dust collection box 210, a dust collection pipe 220, and a protrusion 230. After the vacuum cleaner 100 returns to base station 200 after cleaning, the dust collection pipe 220 connects to the vacuum cleaner 100, and its top protrusion 230 abuts against the opening part 122 of the bottom cover 120, forcing the bottom cover 120 to rotate towards the base station 200 to open the dust discharge port 111, so that the dust cup 110 is connected to the dust collection box 210. At the same time, the fan inside base station 200 generates a strong suction, sucking foreign objects in the dust cup 110 into the dust collection box 210 through the dust collection pipe 220, completing automatic dust collection, avoiding frequent cleaning of the dust cup 110 by the user, and making the cleaning process more hygienic and convenient.

[0081] In summary, the cleaning system 001 provided by this utility model enables the automatic opening of the bottom cover 120 when the vacuum cleaner 100 is connected to the base station 200, without requiring manual operation by the user. This allows for the smooth discharge of foreign objects from the dust cup 110 even if the user's hands are dusty or in a less convenient operating position, greatly improving operational convenience.

[0082] Furthermore, the cleaning system 001 automatically opens through the cooperation of the dust collection pipe 220 and the protrusion 230 of the base station 200 with the bottom cover 120 of the vacuum cleaner 100. Compared to the complex mechanical structure required for manually opening and closing the bottom cover 120 in the traditional method, the structure is much simpler. The simplified structure reduces the manufacturing cost of the product. At the same time, due to the reduction of complex mechanical parts, the possibility of wear and tear and failure of parts caused by frequent operation during long-term use is also reduced, thereby improving the reliability and service life of the product.

However, it will be readily understood by those skilled in the art that the protection scope of this utility model is not limited to these specific embodiments. Without departing from the technical principles of this utility model, those skilled in the art can disassemble and combine the technical solutions in the above embodiments, and can also make equivalent changes or substitutions to the relevant technical features. Any changes, equivalent substitutions, improvements, etc., made within the technical concept and / or technical principles of this utility model will fall within the protection scope of this utility model.
