Description

Technical Field

[0001] This invention relates to the field of vacuum cleaner technology, specifically a connection structure between a vacuum cleaner base station and a vacuum cleaner main unit. Background Technology

[0002] Currently, with the continuous updates and iterations in vacuum cleaner design and usage concepts, the use of vacuum cleaner base stations is gradually increasing to ensure long-term standby and cruise use of the vacuum cleaner main unit and functions such as dust collection. Although these base stations can achieve dust cup dust collection and vacuum cleaner main unit charging, the discharge and dust collection of dust and dirt from the multiple dust collection chambers arranged axially within the common vacuum cleaner dust cup remains difficult. It still requires disassembling the vacuum cleaner main unit, opening each dust collection chamber, and then emptying and collecting the dirt from the vacuum cleaner main unit, which is cumbersome and troublesome. The connection, assembly, positioning, and dust collection of the vacuum cleaner main unit and the base station largely rely on the motor inside the base station. However, the positioning effect of the vacuum cleaner main unit is not ideal, resulting in low airflow guidance and dust collection efficiency. Furthermore, the cost of vacuum cleaners is relatively high. When the motor inside the base station is running, vibration between the base station and the vacuum cleaner main unit is unavoidable, leading to frequent collisions and wear, reducing their lifespan, and further decreasing the positioning and dust collection efficiency of the vacuum cleaner main unit. Summary of the Invention

[0003] The purpose of this invention is to address the difficulties in dust and dirt removal and waste collection in common vacuum cleaner base stations, which still require disassembling the vacuum cleaner main unit, opening each dust collection chamber, and then removing and collecting the dirt from the vacuum cleaner main unit. This process is cumbersome and troublesome. The connection, assembly, positioning, and waste collection between the vacuum cleaner main unit and the base station largely rely on the motor inside the base station. However, the positioning effect of the vacuum cleaner main unit is poor, resulting in low airflow guidance and waste collection efficiency. Furthermore, the cost of the vacuum cleaner is relatively high. When the motor inside the base station is running, vibration between the base station and the vacuum cleaner main unit is unavoidable, leading to frequent collisions and wear, reduced lifespan, and further decreased positioning and waste collection efficiency of the vacuum cleaner main unit. Therefore, this invention provides a connection structure between the vacuum cleaner base station and the vacuum cleaner main unit.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a connection structure between a vacuum cleaner base station and a vacuum cleaner main unit, comprising:

[0005] Vacuum cleaner main unit;

[0013] As a further description of the above technical solution:

[0014] The connector is provided with a first retainer on the side facing the dust collection structure, and the first retainer is fitted onto the dust collection structure.

[0015] As a further description of the above technical solution:

[0016] A second sleeve extends from the inner side of the first sleeve and slides onto the guide block on the side of the dust collection structure. The guide block has a T-shaped structure.

[0017] As a further description of the above technical solution:

[0018] The dust cup inlet is connected to the conical filter structure inside the first dust collection chamber. A filter screen is installed on the conical filter structure. The air outlet of the conical filter structure is connected to the second dust collection chamber. A HEPA structure is installed inside the second dust collection chamber. The HEPA structure is connected to the vacuum motor inside the vacuum cleaner main unit and is connected to the outside through the main air outlet of the vacuum cleaner.

[0019] As a further description of the above technical solution:

[0020] The second snap-fit ​​part is a T-shaped structure with reinforcing ribs on the side. The sleeve structure has a T-shaped slot on the side opposite to the notch. The T-shaped slot is sleeved on the second snap-fit ​​part, and the abutting platform at the bottom of the T-shaped slot abuts and positions the second snap-fit ​​part.

[0021] As a further description of the above technical solution:

[0022] The dust discharge channel includes a conical channel located at the bottom of the jacket structure and a curved channel that connects with the dust discharge port and the second snap-fit ​​part. The conical channel does not interfere with the opening, closing and rotation of the dust cup cover.

[0023] As a further description of the above technical solution:

[0024] The top of the base is provided with a first connecting air duct and a second connecting air duct that are tightly inserted and spliced ​​with the bottom ends of the conical channel and the curved channel, respectively.

[0029] In summary, due to the adoption of the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0030] 1. This vacuum cleaner base station's connection structure addresses the difficulty of dust and dirt discharge and waste collection in the vacuum cleaner's main unit, which is typically arranged along the axial direction of the main unit's internal dust collection chambers, when the base station and main unit are connected. The design incorporates a dust discharge channel, allowing the multiple dust collection chambers to connect directly to the main unit without disassembling the main unit. This eliminates the need to disassemble the main unit; simply opening each chamber allows for easy discharge and collection of dirt from the main unit, simplifying operation. The dust collection structure, combined with the embedded assembly and tenon-and-mortise joint positioning, prevents circumferential rotation and radial / axial displacement of the main unit after it is mounted on the base station. This ensures stable positioning of the main unit and efficient operation of base station functions such as dust discharge and charging. Compared to common vacuum cleaner base stations that use an internal motor for docking, positioning, and dust cup extraction, this base station's connection to the vacuum cleaner's main unit involves pressing a switch on the main unit during dust collection. This opens the dust cup lid, and the vacuum motor inside the main unit creates an airflow opposite to the airflow during dust collection. This negative pressure environment within the base station forces dust out of the main unit and into the base station, ensuring complete and efficient dust removal while reducing operating costs. Furthermore, it allows for backwashing of the filter in the main unit's filter structure, cleaning it and reducing clogging after each use. This decreases the frequency of filter removal and cleaning, improving the user experience for both the main unit and the base station.

[0031] 2. The elastic connection structure between the dust collection pipe, connectors, and elastic components, and the side of the dust cup, allows for moderate movement and flexibility. This reduces the impact and wear between the dust collection pipe end and the dust cup caused by the intense vibration of airflow and dust during vacuum cleaner operation. This extends the lifespan of the dust collection structure and reduces or eliminates misalignment between the dust collection pipe and the dust cup inlet, ensuring stable, leak-free, and efficient airflow. Furthermore, this design reduces the impact of vacuum motor vibration and airflow / dust impact on the vacuum cleaner base station when the vacuum cleaner main unit is mounted on it for waste collection. This ensures a stable connection between the dust cup exhaust port and the dust collection base station's exhaust channel, achieving leak-free waste discharge and recycling.

[0049] Example 1:

[0050] Please see Figure 1-8 This invention provides a technical solution: a connection structure between a vacuum cleaner base station and a vacuum cleaner main unit, comprising:

[0051] Vacuum cleaner main unit 1;

[0052] The vacuum cleaner dust cup 4 is located at the front end of the vacuum cleaner main unit 1, with a dust cup cover 45 at the end, a first snap-fit ​​part 41 and a second snap-fit ​​part 48 arranged opposite each other on the side, and a first dust collection chamber 44 and a second dust collection chamber 46 arranged inside along its axial direction.

[0053] The first dust collection chamber 44 is directly opposite the dust cup cover 45. The second snap-fit ​​part 48 is provided with a dust discharge port 461 that connects to the second dust collection chamber 46 and is provided with a cover. The vacuum cleaner main unit 1 is provided with a switch to control the opening and closing of the dust cup cover 45 and the operation of the motor inside the vacuum cleaner main unit.

[0054] The dust collection structure 3 is embedded in the vacuum cleaner main unit 1 at the rear end and is elastically snapped onto the side of the vacuum cleaner dust cup 4 at the front end. The internal dust collection air duct 313 is connected to the dust cup inlet 42 of the vacuum cleaner dust cup 4.

[0055] The vacuum cleaner base station 2 includes a sleeve structure 21 and a base 22. A jacket structure 211 is provided on the sleeve structure 21, and the jacket structure 211 has a lateral opening notch 212. The vacuum cleaner dust cup 4 is inserted into the jacket structure 211, and the dust collection structure 3 passes through the notch 212. The vacuum cleaner base station 2 has a dust discharge channel corresponding to the dust cup cover 45 and the dust discharge port 461. The dust discharge channel connects to the base station dust cup 23 inside the base 22. The base station dust cup 23 is detachably mounted on the base 22, and an exhaust structure is provided on the base station dust cup 23. In this embodiment, multiple second dust collection chambers 46 can be arranged along the axis of the vacuum cleaner main unit 1, each corresponding to a dust discharge port of the dust discharge channel.

[0056] This vacuum cleaner base station's connection structure addresses the challenge of difficult dust and dirt removal and waste collection operations when the multiple dust collection chambers, distributed along the internal axis of the vacuum cleaner unit, are connected during docking. The improved design utilizes a dust extraction channel, allowing multiple dust collection chambers to align with the vacuum cleaner unit after docking. This eliminates the need to disassemble the vacuum cleaner unit; simply opening each chamber allows for easy removal and collection of dirt from the vacuum cleaner unit, simplifying operation. The dust collection structure, combined with the embedded assembly and tenon-and-mortise joint positioning, prevents circumferential rotation and radial / axial displacement of the vacuum cleaner unit after mounting. This ensures stable positioning of the vacuum cleaner unit and efficient operation of base station functions such as dust removal and charging. Compared to common vacuum cleaner base stations that use an internal motor for docking, positioning, and dust cup extraction, this base station's connection to the vacuum cleaner's main unit involves pressing a switch on the main unit during dust collection. This opens the dust cup lid, and the vacuum motor inside the main unit creates an airflow opposite to the airflow during dust collection. This negative pressure environment within the base station forces dust out of the main unit and into the base station, ensuring complete and efficient dust removal while reducing operating costs. Furthermore, it allows for backwashing of the filter in the main unit's filter structure, cleaning it and reducing clogging after each use. This decreases the frequency of filter removal and cleaning, improving the user experience for both the main unit and the base station.

[0057] In this embodiment, the design of the filtration and airflow guiding structure and dust collection chamber inside the vacuum cleaner main unit 1 is as follows: the dust cup inlet 42 is connected to the conical filter structure 43 inside the first dust collection chamber 44, a filter screen is provided on the conical filter structure 43, the air outlet of the conical filter structure 43 is connected to the second dust collection chamber 46, a HEPA structure 47 is provided inside the second dust collection chamber 46, and the HEPA structure 47 is connected to the vacuum motor inside the vacuum cleaner main unit 1 and connected to the outside through the main air outlet of the vacuum cleaner.

[0058] Please see Figure 6 When the vacuum cleaner main unit 1 is used for cleaning, the internal airflow is as shown by the solid arrow in the figure. The dust collection structure 3 is aligned with the surface to be cleaned, so that the airflow generated by the vacuum motor in the vacuum cleaner main unit 1 draws the surface dust into the dust collection tube 31. Through the dust cup inlet 42, the dust-laden airflow moves to the cone-shaped filter structure 43. After preliminary filtration, the dust settles into the first dust collection chamber 44, at which point the dust cup cover 45 is tightly closed. The airflow enters the cone-shaped filter structure 43 and then moves to the second dust collection chamber 46. At this point, the dust outlet 461 is blocked, and the HEPA structure 47 performs secondary purification of the airflow and dust interception, causing the dust to settle to the bottom of the second dust collection chamber 46, while the clean airflow is discharged from the vacuum cleaner main unit 1. This makes the filtration in the vacuum cleaner main unit 1 highly efficient and the dust settling in each dust collection chamber stable.

[0059] When the vacuum cleaner main unit 1 is assembled on the vacuum cleaner base station 2, the vacuum cleaner dust cup 4 is inserted into the jacket structure 211, and the dust collection structure 3 is inserted into the notch 212, so as to realize the mortise and tenon connection and assembly positioning of the vacuum cleaner main unit 1 and the vacuum cleaner base station 2. The dust cup cover 45 and the dust discharge port 461 are connected with the dust discharge channel in the vacuum cleaner base station 2 one by one, and the sealing connection is achieved by the sealing gasket at the connection.

[0060] Continue reading Figure 6 When the vacuum cleaner main unit 1 discharges garbage and the vacuum cleaner base station 2 collects garbage, the main airflow inside the vacuum cleaner base station 2 is as shown by the dotted arrow in the figure. The main airflow direction in the first dust collection chamber 44 of the dust collection structure 3 and the vacuum cleaner dust cup 4 remains unchanged, while the main airflow in the second dust collection chamber 46 is opposite and forms an airflow towards the dust discharge port 461. Pressing the switch on the vacuum cleaner main unit 1 opens the dust cup cover 45, causing the vacuum motor to rotate in reverse. The airflow washes the HEPA structure 47 and carries the dirt and debris in the second dust collection chamber 46 into the dust discharge channel of the vacuum cleaner base station 2 through the dust discharge port 461. Another airflow flows into the first dust collection chamber 44 through the dust collection pipe 31, carrying the debris therein into the dust discharge channel of the vacuum cleaner base station 2. This achieves the discharge of dirt and debris from multiple dust collection chambers. Without disassembling the vacuum cleaner main unit 1 and with the dust collection chambers open, the debris in the vacuum cleaner main unit 1 can be efficiently discharged, making the operation of the vacuum cleaner main unit 1 and the vacuum cleaner base station 2 cleaner.

[0061] Example 2:

[0062] Please see Figure 2-3 Based on the above embodiment 1, preferably, the connection structure between the dust collection structure 3 and the vacuum cleaner dust cup 4 and the vacuum cleaner base station 2 is as follows: an L-shaped positioning member 312 is provided on the side of the dust collection pipe 31 at the end of the dust collection structure 3 facing the vacuum cleaner dust cup 4, a connecting member 32 is provided between the L-shaped positioning member 312 and the first snap-fit ​​part 41, an elastic member 33 is provided between one side of the connecting member 32 and the inner side of the L-shaped positioning member 312. In this embodiment, the elastic member 33 is a spring. A wedge-shaped or arc-shaped locking block 323 is provided on the other side of the connecting member 32. The locking block 323 is snapped into the slot on the opposite side of the first snap-fit ​​part 41.

[0063] The aforementioned structure allows for a flexible connection between the dust collection pipe 31 and the dust cup 4, enabling moderate movement. This reduces the impact and wear between the end of the dust collection pipe 31 and the dust cup 4 caused by the intense vibrations from airflow and dust during vacuum cleaner operation. This extends the lifespan of the dust collection structure 3 and reduces or prevents misalignment between the dust collection pipe 31 and the dust cup inlet 42 of the dust cup 4, ensuring stable, leak-free, and efficient airflow. Furthermore, this design reduces the impact of vacuum motor vibration and airflow / dust impact on the vacuum cleaner base station 2 when the vacuum cleaner main unit 1 is mounted on the base station 2 for waste collection. This ensures a stable connection between the dust cup 4's exhaust port and the base station 2's exhaust channel, achieving leak-free waste discharge and collection.

[0064] In this embodiment, the connector 32 is provided with a first sleeve 321 on the side facing the dust collection structure 3, and the first sleeve 321 is sleeved on the dust collection structure 3.

[0065] A second sleeve 322 extends from the inner side of the first sleeve 321. The second sleeve 322 is slidably sleeved on the guide block 311 on the side of the dust collection structure 3. The guide block 311 has a T-shaped structure.

[0066] The two ferrule structures on the connector 32, in conjunction with the corresponding structures on the dust collection structure 3 and the vacuum cleaner dust cup 4, can further limit the range of motion of the elastic connection structure of the dust collection structure 3 and the vacuum cleaner dust cup 4, ensuring the stability of this connection structure, leak-free flow guidance, and vibration impact buffering effect.

[0067] Example 3:

[0068] Please see Figure 2 , 45. Based on the above embodiment 1, preferably, in this embodiment, based on the docking structure between the vacuum cleaner host 1 and the vacuum cleaner base station 2 realized by the above dust collection structure 3, further design is carried out for the docking assembly guidance and positioning of the two. The specific structure is as follows: the second snap-fit ​​part 48 is a T-shaped structure with reinforcing ribs on the side. The sleeve structure 21 is provided with a T-shaped slot 213 on the opposite side of the notch 212. The T-shaped slot 213 is sleeved on the second snap-fit ​​part 48. The abutting platform at the bottom of the T-shaped slot 213 abuts and positions the second snap-fit ​​part 48.

[0069] When assembling the vacuum cleaner main unit 1 and the vacuum cleaner base station 2, the bottom of the vacuum cleaner dust cup 4 is first inserted into the jacket structure 211, and the dust collection structure 3 is simultaneously inserted into the notch 212. The vacuum cleaner main unit 1 is then pressed in, causing the second snap-fit ​​part 48 to align with the T-shaped slot 213. When the abutting platform at the bottom of the T-shaped slot 213 abuts and aligns with the second snap-fit ​​part 48, the assembly of the vacuum cleaner main unit 1 and the vacuum cleaner base station 2 is complete, and the dust discharge port of the vacuum cleaner dust cup 4 is aligned with the dust discharge channel of the vacuum cleaner base station 2. This design makes the assembly operation of the vacuum cleaner main unit 1 and the vacuum cleaner base station 2 more standardized, ensuring convenient operation of the connection between the vacuum cleaner main unit 1 and the vacuum cleaner base station 2, and stable and efficient waste collection.

[0070] Example 4:

[0071] Please see Figure 6-8 Based on the above embodiment one, preferably, in this embodiment, the dust exhaust channel within the vacuum cleaner base station 2 is designed in a more refined manner. Specifically, the dust exhaust channel includes a conical channel 214 located at the bottom of the jacket structure 211 and a curved channel 215 that connects to the dust exhaust port 461 and the second snap-fit ​​part 48. The conical channel 214 does not interfere with the opening, closing, or rotation of the dust cup cover 45. The conical channel 214 design, while ensuring efficient airflow guidance and dust discharge, provides sufficient space for the opening and closing of the dust cup cover 45, avoiding interference from other structures and achieving efficient, zero-suction-loss guidance of airflow and dust by the dust cup cover 45.

[0072] The curved channel 215 is designed based on the side air outlet and dust discharge of the dust cup 4 of the vacuum cleaner, so as to achieve efficient guidance of airflow and dust without suction loss.

[0073] The base 22 has a first connecting air duct 221 and a second connecting air duct 222 on its top, which are respectively tightly inserted and spliced ​​with the bottom ends of the conical channel 214 and the curved channel 215. The ends of the first connecting air duct 221 and the second connecting air duct 222 are respectively provided with a first connecting port 223 and a second connecting port 224 that mate with the top and side of the base station dust cup 23. The above design allows the long dust exhaust channel inside the vacuum cleaner base station 2 to be disassembled. Through the interlocking and insertion, the structural strength and airflow efficiency of the dust exhaust channel are ensured, and the assembly of the vacuum cleaner base station 2 is also facilitated.

[0074] The base station dust cup 23 is provided with a connecting groove 231 that fits tightly with the first connecting port 223. The bottom of the connecting groove 231 is provided with a first dust discharge inlet 232 that communicates with the dust storage cavity inside the base station dust cup 23. The base station dust cup 23 is provided with a second dust discharge inlet 233 that fits tightly with the second connecting port 224.

[0075] The above design includes dust discharge channels within the vacuum cleaner base station 2, corresponding to the dust discharge from the bottom of the dust cup on the dust cup cover 45 and the dust discharge from the side of the dust cup on the dust cup outlet 461. This design prevents dust and debris from clogging the dust discharge channels, thus avoiding increased cleaning costs for the vacuum cleaner base station 2.

[0076] During waste collection, dust discharged from the bottom of the vacuum cleaner's dust cup 4 is guided by the dust cup cover 45 and the conical channel 214, and enters the base station dust cup 23 through the first connection port 223, the connecting groove 231, and the first dust exhaust inlet 232. Waste discharged from the side of the vacuum cleaner's dust cup 4 enters the curved channel 215 through the dust exhaust port 461, moves downwards into the second connecting air duct 222, and then enters the base station dust cup 23 through the connecting second connection port 224 and the second dust exhaust inlet 233, achieving efficient and complete recycling of waste within the vacuum cleaner's dust cup 4. The combination of the first connection port 223 and the connecting groove 231, along with other design features, enhances the structural strength at the corners of the dust exhaust channel, thereby ensuring efficient and lossless guidance of airflow and dust, enabling efficient use of the vacuum cleaner.

[0077] Example 5:

[0078] Please see Figure 1 Based on the above embodiment one, preferably, the exhaust structure is an exhaust port located on one side of the base station dust cup 23 and connected to the outside, and the exhaust port is equipped with an air outlet filter.

[0079] The above structure is used for exhaust of the base station dust cup 23 during garbage collection of the vacuum cleaner base station 2. The airflow discharged from the base station dust cup 23 is filtered through the exhaust filter to ensure the cleanliness of the vacuum cleaner base station 2 and its pollution-free use.

[0080] In summary, due to the adoption of the above technical solution, the connection structure between the vacuum cleaner base station and the vacuum cleaner host in this embodiment has the following advantages compared with the prior art:

[0081] 1. This vacuum cleaner base station's connection structure addresses the difficulty of dust and dirt discharge and waste collection in the vacuum cleaner's main unit, which is typically arranged along the axial direction of the main unit's internal dust collection chambers, when the base station and main unit are connected. The design incorporates a dust discharge channel, allowing the multiple dust collection chambers to connect directly to the main unit without disassembling the main unit. This eliminates the need to disassemble the main unit; simply opening each chamber allows for easy discharge and collection of dirt from the main unit, simplifying operation. The dust collection structure, combined with the embedded assembly and tenon-and-mortise joint positioning, prevents circumferential rotation and radial / axial displacement of the main unit after it is mounted on the base station. This ensures stable positioning of the main unit and efficient operation of base station functions such as dust discharge and charging. Compared to common vacuum cleaner base stations that use an internal motor for docking, positioning, and dust cup extraction, this base station's connection to the vacuum cleaner's main unit involves pressing a switch on the main unit during dust collection. This opens the dust cup lid, and the vacuum motor inside the main unit creates an airflow opposite to the airflow during dust collection. This negative pressure environment within the base station forces dust out of the main unit and into the base station, ensuring complete and efficient dust removal while reducing operating costs. Furthermore, it allows for backwashing of the filter in the main unit's filter structure, cleaning it and reducing clogging after each use. This decreases the frequency of filter removal and cleaning, improving the user experience for both the main unit and the base station.

[0082] 2. The elastic connection structure between the dust collection pipe, connectors, and elastic components, and the side of the dust cup, allows for moderate movement and flexibility. This reduces the impact and wear between the dust collection pipe end and the dust cup caused by the intense vibration of airflow and dust during vacuum cleaner operation. This extends the lifespan of the dust collection structure and reduces or eliminates misalignment between the dust collection pipe and the dust cup inlet, ensuring stable, leak-free, and efficient airflow. Furthermore, this design reduces the impact of vacuum motor vibration and airflow / dust impact on the vacuum cleaner base station when the vacuum cleaner main unit is mounted on it for waste collection. This ensures a stable connection between the dust cup exhaust port and the dust collection base station's exhaust channel, achieving leak-free waste discharge and recycling.
