Abstract
Description
Technical Field
[0001] This disclosure belongs to the field of cleaning equipment technology, specifically relating to a base station and a cleaning system. Background Technology
[0002] Stick vacuum cleaners typically have a slender main body. Components such as the dust chamber, fan, battery, and handle are arranged along or near the main body. The entire machine needs to maintain a stable relative position with the base station when parked, charging, or collecting dust. Some stick vacuum cleaners have a dust exhaust port in the dust chamber, while the base station has a dust collection port for receiving dust. When the base station performs dust collection, the exhaust port needs to be aligned with the dust collection port so that dust from the dust chamber can enter the dust collection channel or chamber within the base station. Summary of the Invention
[0003] When placing a stick vacuum cleaner on a base station, it can be held in place by the base station's recesses, mounting points, magnetic attachments, or support structures. While this structure meets basic storage needs, in scenarios where the base station requires dust collection, simply ensuring the vacuum cleaner is roughly positioned on the station is insufficient to guarantee a tight seal between the exhaust and collection ports. Furthermore, the stick vacuum cleaner's relatively long body makes its center of gravity somewhat unstable, potentially causing slight tilting or swaying when placed by the user.
[0004] When the dust exhaust port and dust collection port fail to fit securely together, a localized gap can easily form between them. During negative pressure dust collection at the base station, outside air can enter the dust collection path through this gap, reducing the negative pressure intensity inside the dust chamber and making it difficult for dust to be discharged smoothly. Fine dust particles may also escape from the gap between the dust exhaust port and the dust collection port, contaminating the outer surface of the base station, the vacuum cleaner housing, and the surrounding environment. For stick vacuum cleaners with small dust chamber capacity and limited exhaust port size, the sealing stability at the interface is more likely to affect the dust collection effect. If users need to repeatedly adjust the vacuum cleaner position to achieve effective docking, it will also reduce the ease of use of the base station.
[0005] Existing base stations rely solely on the natural contact between the dust exhaust port and the dust collection port, making it difficult to ensure a consistently stable pressure applied to the dust collection port by the stick vacuum cleaner in its final parking position. Insufficient pressure makes it difficult for the seal to deform sufficiently. Unstable pressure direction can lead to localized pressure and partial suspension of the seal, resulting in inconsistent airtightness at the connection point. Especially when the stick vacuum cleaner's main body is of considerable length and has a high center of gravity, changes in the main body's posture are amplified at the dust exhaust port, making the relative posture between the exhaust and collection ports even more difficult to control.
[0006] In view of the aforementioned technical problems, the purpose of this disclosure is to provide a base station and a cleaning system that can achieve reliable alignment and sealing between the dust discharge port of a stick vacuum cleaner and the dust collection port of the base station.
[0007] To achieve the above objectives, the technical solution provided in this disclosure is as follows:
[0008] In a first aspect, this disclosure provides a base station for a stick vacuum cleaner, comprising a base body, a sealing element, and a limiting structure. The base body has a dust collection port for docking with the dust exhaust port of the stick vacuum cleaner. The sealing element is disposed at the dust collection port. The limiting structure is disposed on the base body and is used for docking with the main body of the stick vacuum cleaner. The limiting structure has a limiting groove extending at an angle relative to the vertical direction. The depth of the limiting groove gradually increases from bottom to top relative to the base body, so that when the main body moves along the limiting groove to a predetermined docking position, the dust exhaust port faces the dust collection port and presses against the sealing element, thereby sealing and communicating between the dust exhaust port and the dust collection port. By guiding the main body to the predetermined docking position through the limiting groove extending at an angle relative to the vertical direction, and using the gravity of the main body of the stick vacuum cleaner to press the dust exhaust port against the sealing element, the alignment accuracy and sealing performance between the dust exhaust port and the dust collection port are improved, reducing the risk of air and dust leakage during dust collection.
[0009] In one or more embodiments, the extending direction of the limiting groove forms a preset angle with the vertical direction, the preset angle being 1° to 15°. By limiting the preset angle between the limiting groove and the vertical direction, the main body rod is moderately offset in a near-vertical placement path, balancing docking convenience and sealing pressure effect.
[0010] In one or more embodiments, the limiting groove has a front opening for the main body rod to enter, and lateral limiting walls are provided on the left and right sides of the front opening. The lateral limiting walls are used to restrict the main body rod from swinging in the left and right direction relative to the base. The front opening facilitates the entry of the main body rod into the limiting groove, and the lateral limiting walls on the left and right sides restrict the left and right swing of the main body rod, so that the main body rod maintains a stable posture during docking and reduces the misalignment of the dust discharge port relative to the dust collection port.
[0011] In one or more embodiments, the limiting groove includes a rear limiting wall disposed opposite to the front opening, the rear limiting wall being used to restrict the termination position of the main body rod entering the limiting groove. By restricting the termination position of the main body rod entering the limiting groove by the rear limiting wall, the consistency of the dust outlet pressing position is improved.
[0012] In one or more embodiments, at least a portion of the wall of the limiting groove forms a pressing guide surface. This pressing guide surface guides the movement of the main body rod when it engages with the limiting groove, causing the dust discharge port to shift towards the side where the dust collection port is located. By guiding the movement of the main body rod through the pressing guide surface, and shifting the dust discharge port towards the side where the dust collection port is located, the guiding process of the main body rod is transformed into a pressing process of the dust discharge port, improving the reliability of the sealing fit between the dust discharge port and the dust collection port.
[0013] In one or more embodiments, the seal is disposed around the dust collection port and has an elastic sealing portion that can be compressed by the outer periphery of the dust discharge port. By using the seal and its elastic sealing portion disposed around the dust collection port, a circumferential seal is formed when the outer periphery of the dust discharge port is pressed against it, compensating for gaps and deviations between the dust discharge port and the dust collection port, and reducing the entry of external air and the escape of dust during the dust collection process.
[0014] In one or more embodiments, the dust collection port has an annular mounting portion surrounding its rim, and the sealing member includes a mounting base connected to the annular mounting portion, with the elastic sealing portion protruding from the mounting base. The connection between the annular mounting portion and the mounting base allows the sealing member to be stably mounted around the rim of the dust collection port, and enables the elastic sealing portion to protrude from the mounting base to form a pressure-sealed area, thus balancing installation stability and sealing deformation capability.
[0015] In one or more embodiments, the annular mounting portion includes an annular mounting groove, and the mounting base is at least partially embedded within the annular mounting groove. By accommodating the mounting base through the annular mounting groove, the seal is positioned relative to the dust collection port, reducing the possibility of displacement or detachment of the seal during repeated connection processes.
[0016] In one or more embodiments, the mounting base is provided with a limiting rib, and the groove wall of the annular mounting groove is provided with a limiting recess that mates with the limiting rib. The limiting rib is at least partially embedded in the limiting recess to prevent the seal from detaching from the annular mounting base. The engagement of the limiting rib and the limiting recess enhances the anti-detachment capability between the mounting base and the annular mounting groove.
[0017] In one or more embodiments, the resilient sealing portion protrudes at least partially along the axial direction of the dust collection port toward the dust discharge port, so as to undergo at least partial resilient compression along the axial direction of the dust collection port when the dust discharge port presses against the seal. By having the resilient sealing portion protrude along the axial direction of the dust collection port toward the dust discharge port, the resilient sealing portion contacts the dust discharge port before the rigid edge of the dust collection port and undergoes resilient compression along the axial direction of the dust collection port, thereby improving the sealing compensation capability.
[0018] In one or more embodiments, the resilient sealing portion includes an annular sealing lip that protrudes from the mating side toward the dust discharge port and surrounds the dust collection port, so as to conform to the outer periphery of the dust discharge port when pressed against the sealing member. By conforming the annular sealing lip to the outer periphery of the dust discharge port, a flexible lip seal is formed around the dust collection port, improving the adaptability of the sealing member to the outer periphery shape and minor deviations of the dust discharge port, and enhancing circumferential sealing performance.
[0019] In one or more embodiments, the limiting structure is provided with a first magnetic suction member, which is used to magnetically engage with a second magnetic suction member on the main body rod to hold the main body rod at the predetermined docking position. By magnetically engaging the first and second magnetic suction members, the main body rod is held at the predetermined docking position, reducing the offset of the main body rod during dust collection and maintaining the pressure of the dust discharge port against the seal.
[0020] In one or more embodiments, the substrate includes a dust collection chamber and a dust collection channel communicating with the dust collection port. The dust collection channel connects the dust collection port and the dust collection chamber, and is used to transmit negative pressure to the dust discharge port after the dust discharge port is connected to the dust collection port. By connecting the dust collection port and the dust collection chamber through the dust collection channel, the negative pressure inside the base station can be transmitted to the dust discharge port through the dust collection channel, and the discharged dust enters the dust collection chamber along a defined path, thereby improving the negative pressure transmission efficiency and dust collection stability.
[0021] In one or more embodiments, the substrate has a clearance space inside the dust collection port, the clearance space being used to allow the dust chamber cover to extend at least partially into the container when the dust chamber cover of the stick vacuum cleaner is opened. By providing a clearance space inside the dust collection port, space is provided for the movement and accommodation of the dust chamber cover after it is opened, interference between the dust chamber cover and the substrate is avoided, and the dust discharge port can be opened smoothly in the docked state.
[0022] In one or more embodiments, the clearance space is provided with a cover limiting surface, which limits the opening angle of the dust chamber cover relative to the closed state to no more than 90°. By limiting the opening angle of the dust chamber cover relative to the closed state through the cover limiting surface, excessive opening of the dust chamber cover is prevented from affecting the sealing connection and dust collection airflow.
[0023] Secondly, this disclosure provides a cleaning system including a stick vacuum cleaner and the base station, the base station being used to interface with the stick vacuum cleaner.
[0024] The base station and cleaning system disclosed herein transform the placement action of the stick vacuum cleaner into a docking action where the dust discharge port presses against the dust collection port by setting a limiting structure on the base to cooperate with the main body of the stick vacuum cleaner. When the main body moves along the limiting groove to the predetermined docking position, the posture of the stick vacuum cleaner is guided and limited by the limiting structure. The dust discharge port moves towards the dust collection port as the posture of the main body adjusts, and presses against the sealing element set at the dust collection port. The sealing element undergoes elastic deformation under the pressure of the dust discharge port, which can compensate for the slight deviation between the dust discharge port and the dust collection port, so that the dust discharge port and the dust collection port form a stable sealed connection.

Detailed Implementation
[0034] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.
[0035] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.
[0036] It should be noted that when an element is described as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. In the embodiments shown in this disclosure, directional representations such as up, down, left, right, front, and back are relative and are used to explain the relative structure and movement of different components in this disclosure. These representations are appropriate when the components are in the positions shown in the figures. However, if the description of the component positions changes, then these representations are considered to change accordingly.
[0037] Stick vacuum cleaners typically have a long, slender body, with a fixed relative position between the dust outlet of the dust chamber and the main body. When a base station collects dust from a stick vacuum cleaner, negative pressure can only be concentrated inside the dust chamber after the dust outlet and the dust collection side of the base station are stably fitted. The inventors discovered that existing base stations focus more on the parking, storage, or charging of stick vacuum cleaners, usually only requiring the vacuum cleaner to be stationary, without fully utilizing the relationship between the posture of the vacuum cleaner body and the position of the dust outlet.
[0038] Even when the stick vacuum cleaner is placed in a relatively stationary position after being placed in the base station, the dust outlet may still fail to form a stable contact with the base station's dust collection side due to deviations in the main body's posture, placement actions, assembly tolerances, or clearances accumulated over long-term use. When the base station starts dust collection, air and dust leaks can easily occur at the interface, affecting the stability of dust collection.
[0039] Based on the above understanding, this disclosure establishes a linkage between the parking posture of the stick vacuum cleaner and the sealing connection of the dust discharge port during dust collection. Through the posture constraint on the base station side, the stick vacuum cleaner forms a predetermined posture as it approaches and enters the base station docking position. With the help of this predetermined posture, the dust discharge port forms a fitting tendency towards the dust collection side of the base station, thereby achieving a relatively stable sealing and pressing state between the dust discharge port and the dust collection side of the base station.
[0040] Based on the aforementioned technical approach, the docking process between the stick vacuum cleaner and the base station involves the base station first constraining the posture of the stick vacuum cleaner's main body. Then, through the structural connection between the main body and the dust outlet, this posture constraint is transformed into a pressing relationship between the dust outlet and the dust collection side of the base station. In this way, the sealing state between the dust outlet and the dust collection side of the base station can be formed synchronously with the docking action of the vacuum cleaner, reducing dust collection airtightness problems caused by random parking postures.
[0041] Specifically, the base station guides and limits the posture of the stick vacuum cleaner body, ensuring that the dust outlet maintains a close fit towards the dust collection side in the final docking state. The sealing structure can compensate for local deviations under pressure. During dust collection at the base station, the risk of air and dust leakage at the interface is reduced, the negative pressure inside the dust chamber is more stable, and dust can enter the base station more smoothly from the dust outlet. This improves the docking reliability between the stick vacuum cleaner's dust outlet and the base station's dust collection side without relying on complex clamping mechanisms.
[0042] Please refer to Figures 1 to 3 As shown, a cleaning system in one embodiment of this disclosure includes a stick vacuum cleaner 100 and a base station 1, the base station 1 being used to dock the stick vacuum cleaner 100.
[0043] Base station 1 is used to receive the stick vacuum cleaner 100 when it is idle or charging or self-cleaning. The stick vacuum cleaner 100 may include a main body for the user to hold or support, and may be connected to a cleaning head 103, a suction tube, or other cleaning accessories as needed. Base station 1 can provide one or more functions for the stick vacuum cleaner 100, such as parking, positioning, holding, charging, dust collection, or accessory storage. The specific structure of base station 1 is not particularly limited, as long as it can establish a detachable docking relationship with the stick vacuum cleaner 100 and maintain the stick vacuum cleaner 100 in a predetermined position or posture after docking.
[0044] In use, the stick vacuum cleaner 100 can be moved by the user to the base station 1 and docked with it. The base station 1 can use its own positioning structure to cooperate with the corresponding part of the stick vacuum cleaner 100, so that the stick vacuum cleaner 100 is not prone to significant shaking or displacement in the docked state, which facilitates subsequent charging, dust collection, maintenance or storage operations, and also reduces the difficulty for the user when placing and retrieving the stick vacuum cleaner 100.
[0045] The stick vacuum cleaner 100 includes a main body 101, a cleaning head 103, a dust chamber 104, a dust outlet 105, and a dust chamber cover 106. The main body 101 constitutes the main support part of the stick vacuum cleaner 100, extends along the length of the stick vacuum cleaner 100, and can be used to house functional components such as the dust chamber 104, fan, battery, and handle. The main body 101 has a slender shape, making it easy for users to hold, push, and steer.
[0046] The cleaning head 103 can be attached to the lower end of the main body 101 for cleaning surfaces. The cleaning head 103 may include a suction inlet, a roller brush, wheels, and an air duct, allowing dust and debris on the surface to enter the vacuum cleaner 100 under airflow. The cleaning head 103 can be fixedly connected, detachably connected, or rotatably connected to the main body 101, allowing the cleaning head 103 to adapt to different cleaning scenarios such as floors, carpets, and corners.
[0047] The dust chamber 104 can be positioned on the main body 101 near the cleaning head 103 to receive and temporarily store dust sucked in by the cleaning head 103. The dust chamber 104 can cooperate with an airflow separation structure, allowing dust-laden airflow to enter the dust chamber 104, where dust is trapped and the filtered airflow continues to flow towards the fan or exhaust duct. The dust chamber 104 can also be positioned near the upper middle part of the main body 101 or the handheld portion, allowing it to form a stable integrated structure with the main body 101 and facilitating user observation of dust levels, disassembly and assembly of the dust chamber 104, or cleaning of its interior.
[0048] The dust discharge port 105 communicates with the dust chamber 104 and is used to discharge dust from the dust chamber 104 during dust removal operations. The dust discharge port 105 can be located on the side of the dust chamber 104, and its specific location can be determined based on the shape of the dust chamber 104, the position of the dust collection port 11 of the base station 1, and the parking posture of the stick vacuum cleaner 100. When the stick vacuum cleaner 100 is docked with the base station 1, the dust discharge port 105 can be aligned with the dust collection port 11 of the base station 1, allowing dust from the dust chamber 104 to enter the base station 1 through the dust discharge port 105. The dust discharge port 105 and the main body rod 101 have a relatively fixed positional relationship. Therefore, by controlling the docking posture of the main body rod 101, the alignment state between the dust discharge port 105 and the dust collection port 11 of the base station 1 can be indirectly controlled.
[0049] The dust chamber cover 106 is used to open or close the dust discharge port 105. When the dust chamber cover 106 is closed, a relatively enclosed dust storage space is formed inside the dust chamber 104, preventing dust from leaking from the dust discharge port 105 during normal cleaning or movement. When the dust chamber cover 106 is open, the dust discharge port 105 is exposed, and the dust inside the dust chamber 104 can be discharged under the action of gravity, negative pressure, dust pushing structure, or airflow. The dust chamber cover 106 can be hinged, slidably connected, or detachably connected to the dust chamber 104, and can be opened and closed in conjunction with elastic elements, locking elements, or a trigger structure on the base station 1 side.
[0050] Please refer to Figures 1 to 3As shown, in one embodiment of this disclosure, the base station 1 includes a base 10, a sealing element 2, and a limiting structure 3. The base 10 is provided with a dust collection port 11 for docking with the dust discharge port 105 of a stick vacuum cleaner 100. The sealing element 2 is provided at the dust collection port 11. The limiting structure 3 is provided on the base 10 and is used for docking with the main body rod 101 of the stick vacuum cleaner 100. The limiting structure 3 has a limiting groove 31 that extends obliquely relative to the vertical direction. The groove depth of the limiting groove 31 relative to the base 10 gradually increases from bottom to top, so that when the main body rod 101 moves along the limiting groove 31 to a predetermined docking position, the dust discharge port 105 faces the dust collection port 11 and presses against the sealing element 2 based on the gravity of the main body rod 101 of the stick vacuum cleaner 100, so that the dust discharge port 105 and the dust collection port 11 are sealed and connected.
[0051] Base station 1 uses base body 10 as its main support, which can be used to install various functional components that cooperate with the swivel vacuum cleaner 100. Base body 10 is provided with a dust collection port 11, which is used to align with the dust discharge port 105 of the swivel vacuum cleaner 100 when it is docked with base station 1. This allows dust from the dust chamber 104 of the swivel vacuum cleaner 100 to enter the dust collection port 11 through the dust discharge port 105, and further enter the dust collection channel 15 or dust collection chamber inside base station 1. The position of the dust collection port 11 corresponds to the position of the dust discharge port 105 when the swivel vacuum cleaner 100 is in a predetermined docking position, so that after docking, the dust discharge port 105 can face the dust collection port 11 and communicate with it.
[0052] A sealing element 2 is disposed at the dust collection port 11 and is arranged around or adjacent to the edge of the dust collection port 11. The sealing element 2 may be made of an elastic material, and when the dust discharge port 105 is pressed against the dust collection port 11, the sealing element 2 can undergo elastic deformation to fill the mating gap between the dust discharge port 105 and the dust collection port 11. In this way, even if there are slight manufacturing tolerances, assembly deviations, or placement deviations between the stick vacuum cleaner 100 and the base station 1, the sealing element 2 can still compensate for the local gaps through its own deformation, so that the dust discharge port 105 and the dust collection port 11 maintain a relatively stable sealed connection.
[0053] The limiting structure 3 is located on the base 10 and engages with the main body 101 of the stick vacuum cleaner 100. The main body 101 is typically a long, slender section extending vertically in the stick vacuum cleaner 100, and it has a relatively fixed positional relationship with the dust chamber 104 and the dust outlet 105. By guiding and limiting the main body 101, the limiting structure 3 indirectly restricts the position and orientation of the dust outlet 105 relative to the dust collection port 11. In other words, the base station 1 can control the overall orientation of the stick vacuum cleaner 100 by constraining this relatively long structural part, the main body 101, so that the dust outlet 105 can gradually move into a suitable sealing and engaging position as the main body 101 moves.
[0054] The limiting structure 3 has a limiting groove 31 that extends at an angle relative to the vertical direction. After the main body rod 101 enters the limiting groove 31, it can move along the extension direction of the limiting groove 31 to a predetermined docking position. Since the limiting groove 31 extends at an angle relative to the vertical direction, the process of the main body rod 101 moving along the limiting groove 31 includes not only positional changes in the downward or upward direction, but also posture adjustments or positional shifts toward the side where the dust collection port 11 is located. When the main body rod 101 moves to the predetermined docking position, the entire stick vacuum cleaner 100 is guided to a predetermined posture by the limiting groove 31, and the dust discharge port 105 then faces the dust collection port 11 and presses against the sealing member 2. The inclined limiting groove 31 can simultaneously perform the functions of guiding, limiting, and sealing the posture.
[0055] The depth of the limiting groove 31 relative to the base 10 gradually increases from bottom to top, allowing the limiting groove 31 to accommodate the main body rod 101 at different height positions. As the main body rod 101 moves along the limiting groove 31, its position relative to the base 10 gradually adjusts with the change in groove depth, thereby causing the stick vacuum cleaner 100 to form a docking posture facing the dust collection port 11. Through the inclined extension and gradual change in groove depth, the limiting groove 31 causes the main body rod 101 to have an offset tendency when entering the predetermined docking position, so that the dust discharge port 105 faces the dust collection port 11 and presses against the sealing member 2. Thus, the placement action of the stick vacuum cleaner 100 can simultaneously complete the alignment and pressing of the dust discharge port 105 and the dust collection port 11, reducing the user's repeated position adjustment operations.
[0056] The predetermined docking position can be understood as the final position when the stick vacuum cleaner 100 and the base station 1 are docked. In this position, the main body 101 is constrained by the limiting groove 31, the dust discharge port 105 corresponds to the dust collection port 11, and the sealing element 2 is pressed against the dust discharge port 105 and elastically compressed. The dust discharge port 105, the sealing element 2, and the dust collection port 11 form a continuous sealed channel, allowing dust in the dust chamber 104 to enter the dust collection port 11 from the dust discharge port 105 under the negative pressure of the base station 1. The limiting groove 31 also reduces the shaking of the stick vacuum cleaner 100 during the dust collection process, reducing the risk of gaps arising between the dust discharge port 105 and the dust collection port 11 due to changes in posture.
[0057] After the user places the main body rod 101 into the limiting groove 31 and moves it into place, the limiting groove 31 guides the stick vacuum cleaner 100 to form a docking posture suitable for dust collection, and the dust discharge port 105 can stably press against the sealing element 2. When the base station 1 collects dust, the risk of air and dust leakage at the docking position is reduced, the negative pressure can be more concentrated inside the dust chamber 104, and the dust discharge process is more stable. Compared with simply relying on the user to manually adjust the position of the dust discharge port 105 or relying on the dust discharge port 105 to naturally fit against the dust collection port 11, this solution uses the inclined guiding effect of the limiting groove 31 to establish the relationship between the posture of the main body rod 101 and the sealing pressure of the dust discharge port 105. The structure is simple, the fit is reliable, and it is suitable for the slender stick vacuum cleaner 100 whose parking posture is prone to deviation.
[0058] Preferably, the extension direction of the limiting groove 31 forms a preset angle with the vertical direction, the preset angle being 1° to 15°. This angle range is used to limit the movement trajectory of the main rod 101 after entering the limiting groove 31, so that the main rod 101 produces a moderate attitude deflection as it approaches the predetermined docking position.
[0059] Since the limiting groove 31 is not perfectly vertical, as the main body rod 101 moves along the limiting groove 31, the overall posture of the stick vacuum cleaner 100 can be gradually adjusted according to the tilt direction of the limiting groove 31, and the position of the dust discharge port 105 relative to the dust collection port 11 also changes accordingly. In this way, the dust discharge port 105 can press against the sealing member 2 towards the dust collection port 11 when it reaches the predetermined docking position, and the sealing member 2 receives a certain amount of elastic compression. This preset included angle is controlled between 1° and 15°, mainly based on the balance between docking guidance and parking stability. The angle range of 1° to 15° allows the limiting groove 31 to maintain a near-vertical guiding shape, facilitating the user to complete the docking according to a natural placement action, while also generating a pressing component towards the dust collection port 11.
[0060] In one exemplary embodiment, please refer to Figure 2 As shown, the limiting groove 31 has a front opening 311 for the main body rod 101 to enter, and lateral limiting walls 312 are provided on the left and right sides of the front opening 311. The lateral limiting walls 312 are used to restrict the main body rod 101 from swinging in the left and right direction relative to the base 10.
[0061] The limiting groove 31 has a front opening 311 for the main body rod 101 to enter. The front opening 311 is open towards the front of the base station 1, allowing the main body rod 101 to enter the limiting groove 31 from the front of the base 10 when the user places the stick vacuum cleaner 100. The front opening 311 provides an entry path for the main body rod 101, avoiding the need for the user to insert the main body rod 101 into a narrow space from above, thus reducing the difficulty of placement. After the main body rod 101 enters the front opening 311, it can continue to move along the limiting groove 31 to the predetermined docking position, and is constrained by the groove wall of the limiting groove 31 during the movement.
[0062] Lateral limiting walls 312 are provided on the left and right sides of the front opening 311, and the lateral limiting walls 312 are arranged along the extension direction of the limiting groove 31. After the main body rod 101 enters the limiting groove 31, the outer peripheral area of the main body rod 101 can contact or maintain a small gap with the lateral limiting walls 312, thereby restricting the main body rod 101 from swinging in the left and right direction relative to the base 10. This left and right direction can be understood as intersecting with the front and back direction of the main body rod 101 entering the limiting groove 31 and being approximately parallel to the width direction of the base 10. Through the combined action of the lateral limiting walls 312 on both sides, the main body rod 101 is less likely to swing left and right within the limiting groove 31, and the overall posture of the stick vacuum cleaner 100 can be maintained within a predetermined range.
[0063] The main body 101 of the stick vacuum cleaner 100 is typically quite long. Even slight swaying at the upper or middle part of the main body 101 can cause a noticeable positional deviation at the dust outlet 105 of the dust chamber 104. If the limiting groove 31 only provides forward and backward guidance and lacks lateral limiting, even if the main body 101 has entered the limiting groove 31, it may still wobble due to the user's placement angle, vibration of the base 10, or disturbances during negative pressure dust collection, thus affecting the alignment stability of the dust outlet 105 and the dust collection port 11. The lateral limiting wall 312 can confine the main body 101 within a predetermined lateral area, making the relative position between the dust outlet 105 and the dust collection port 11 more stable.
[0064] Specifically, please refer to Figure 2 As shown, the limiting groove 31 includes a rear limiting wall 313 disposed opposite to the front opening 311. The rear limiting wall 313 is used to limit the main body rod 101 to the termination position of entering the limiting groove 31.
[0065] The rear limiting wall 313 is located at the end of the movement path of the main body rod 101 after it enters the limiting groove 31. The front opening 311 allows the main body rod 101 to enter the limiting groove 31, while the rear limiting wall 313 limits the extreme position of the main body rod 101 as it continues to move toward the inside of the base 10. After the main body rod 101 enters the limiting groove 31 through the front opening 311, it can gradually approach the rear limiting wall 313 under the guidance of the groove wall of the limiting groove 31. When the main body rod 101 moves to a position that abuts against or is adjacent to the rear limiting wall 313, the process of the main body rod 101 entering the limiting groove 31 ends, and the stick vacuum cleaner 100 forms a predetermined docking position relative to the base 10.
[0066] The sealing fit between the dust discharge port 105 and the dust collection port 11 requires a relatively stable front-to-back positional relationship. If the limiting groove 31 lacks a rear limiting wall 313, the insertion depth of the main body rod 101 may change due to different user operating forces, and the pressing position of the dust discharge port 105 relative to the dust collection port 11 and the compression of the seal 2 will also change accordingly. When the main body rod 101 does not enter sufficiently, the dust discharge port 105 may not be able to fully press against the seal 2. When the main body rod 101 enters too deeply, the dust discharge port 105 may exert excessive pressure on the seal 2, causing excessive local deformation of the seal 2, affecting the life of the seal 2 or the flow state of the dust collection port 11.
[0067] Further, please refer to Figure 2 As shown, at least a portion of the groove wall of the limiting groove 31 forms a pressing guide surface 314. The pressing guide surface 314 is used to guide the main body rod 101 to move when it docks with the limiting groove 31, so that the dust discharge port 105 is offset toward the side where the dust collection port 11 is located.
[0068] The pressing guide surface 314 is located on the movement path of the main body rod 101 after it enters the limiting groove 31, and forms a guiding engagement with the outer peripheral area of the main body rod 101. When the main body rod 101 mates with the limiting groove 31, the main body rod 101 first enters the groove cavity through the opening area of the limiting groove 31, and then contacts or is adjacent to the pressing guide surface 314. Since the pressing guide surface 314 has a predetermined tilt or offset relationship with the entry direction of the main body rod 101, when the main body rod 101 continues to move, it will generate a displacement component in the predetermined direction under the constraint of the pressing guide surface 314, thereby causing the overall posture of the stick vacuum cleaner 100 to be adjusted.
[0069] After the main body rod 101 is moved by the pressing guide surface 314, the dust discharge port 105 can adjust its position according to the posture of the main body rod 101 and shift towards the side where the dust collection port 11 is located. This allows the dust discharge port 105 to gradually approach the dust collection port 11 before entering the final docking state, avoiding a hard collision or random contact between the dust discharge port 105 and the dust collection port 11 only in the final stage. The pressing guide surface 314 can be formed in the lateral limiting wall 312 of the limiting groove 31, and can be in the form of a plane, arc, inclined surface, or composite curved surface to adapt to the outer contour of the main body rod 101. The outer periphery of the main body rod 101 can slide on the pressing guide surface 314, or be limited and guided by the pressing guide surface 314 within a small gap.
[0070] During dust collection at base station 1, the sealing state between the dust discharge port 105 and the dust collection port 11 affects negative pressure transmission and dust leakage control. The pressing guide surface 314 causes the dust discharge port 105 to shift towards the dust collection port 11 during docking, reducing the misalignment gap between them and making the seal 2 more stable under pressure. This structure utilizes the groove wall of the limiting groove 31 itself to achieve attitude adjustment and pressing guidance, eliminating the need for a complex active pushing mechanism. This simplifies the structure of base station 1 and improves the positioning accuracy of the stick vacuum cleaner 100 during docking and dust collection.
[0071] In one exemplary embodiment, please refer to Figure 2 , Figure 4 and Figure 6 As shown, the seal 2 is disposed around the dust collection port 11 and has an elastic sealing portion 21 that can be compressed by the outer periphery of the dust discharge port 105.
[0072] The sealing element 2 is arranged around the dust collection port 11, forming a continuous or substantially continuous sealing area around the circumferential edge of the dust collection port 11. The sealing element 2 can be arranged along the outer periphery of the dust collection port 11 or embedded in the mounting part around the dust collection port 11, so that the sealing element 2 and the dust collection port 11 maintain a stable relative position. When the stick vacuum cleaner 100 is docked with the base station 1, the dust discharge port 105 moves toward the dust collection port 11, and the outer periphery of the dust discharge port 105 contacts the sealing element 2 and compresses the elastic sealing part 21. The elastic sealing part 21 undergoes elastic deformation after being compressed, thereby filling any gap that may exist between the outer periphery of the dust discharge port 105 and the edge of the dust collection port 11.
[0073] The elastic sealing part 21, as the deformation area involved in sealing within the sealing element 2, can be made of rubber, silicone, foam, or other materials with elastic recovery capabilities. After the outer periphery of the dust discharge port 105 presses against the elastic sealing part 21, the elastic sealing part 21 can undergo local adaptive deformation according to the shape of the outer periphery of the dust discharge port 105 and the pressing direction. Even if there are slight processing errors, assembly deviations, or docking posture deviations between the dust discharge port 105 and the dust collection port 11, the elastic sealing part 21 can still compensate for these deviations through compression, maintaining the continuity of the air passage between the dust discharge port 105 and the dust collection port 11.
[0074] The design of the seal 2 surrounding the dust collection port 11 ensures that the outer periphery of the dust discharge port 105 receives circumferential sealing support. This surrounding arrangement forms a closed sealing boundary around the dust collection port 11, allowing the negative pressure generated by the base station 1 to act more concentratedly on the dust discharge port 105 and the interior of the dust chamber 104. This reduces the possibility of external air entering the dust collection path through the docking gap and also reduces the risk of fine dust escaping from the docking point. The elastic sealing part 21, after being compressed by the outer periphery of the dust discharge port 105, also provides a certain degree of flexible support and buffering for the dust discharge port 105. During the docking process of the stick vacuum cleaner 100, the dust discharge port 105 will not directly collide with the edge of the dust collection port 11, and the corresponding structures of the base station 1 and the stick vacuum cleaner 100 are less prone to wear due to repeated docking.
[0075] Specifically, please refer to Figures 4 to 6 As shown, the dust collection port 11 has an annular mounting portion 12 arranged around its edge, and the sealing member 2 includes a mounting base 22 connected to the annular mounting portion 12, and an elastic sealing portion 21 protruding from the mounting base 22.
[0076] The annular mounting portion 12 extends circumferentially along the dust collection port 11 and provides a mounting base for the seal 2. The annular mounting portion 12 can be integrally formed with the base 10 or serve as an independent structure connected to the base 10. Its position is adjacent to the edge of the dust collection port 11, allowing the seal 2 to form a continuous sealing area around the dust collection port 11 after installation. By placing the annular mounting portion 12 on the periphery of the edge of the dust collection port 11, the relative position between the seal 2 and the dust collection port 11 can remain stable, preventing the seal 2 from shifting or partially folding during repeated pressing against the dust discharge port 105.
[0077] The mounting base 22 can extend circumferentially along the annular mounting portion 12 and engage with it through fitting, snap-fitting, sleeve-fitting, adhesive bonding, or press-fitting, so that the seal 2 is reliably held at the dust collection port 11. The mounting base 22 can have a larger cross-sectional thickness or higher structural strength relative to the elastic sealing portion 21 to enhance the installation stability of the seal 2. In this way, when the seal 2 is pressed against the dust discharge port 105, the mounting base 22 is less likely to detach from the annular mounting portion 12, and the deformation of the elastic sealing portion 21 is more likely to be concentrated in the predetermined sealing area.
[0078] The elastic sealing part 21 protrudes from the mounting base 22 and forms a compressible sealing contact area towards the mating side of the dust discharge port 105. When the stick vacuum cleaner 100 is mated to the base station 1, the dust discharge port 105 approaches the dust collection port 11 and presses against the elastic sealing part 21. The elastic sealing part 21 undergoes elastic deformation under pressure to compensate for the small gap between the dust discharge port 105 and the dust collection port 11. The mounting base 22 is responsible for maintaining the position of the seal 2, and the elastic sealing part 21 is responsible for forming a sealing contact, so that the seal 2 has both installation reliability and sealing adaptability. This structure can reduce the risk of the seal 2 shifting as a whole due to uneven force, and form a more stable sealed connection between the dust discharge port 105 and the dust collection port 11.
[0079] Further, please refer to Figures 4 to 6 As shown, the annular mounting portion 12 includes an annular mounting groove 13, and the mounting base 22 is at least partially embedded in the annular mounting groove 13.
[0080] An annular mounting groove 13 is arranged circumferentially along the dust collection port 11 and located near the edge of the dust collection port 11. The annular mounting groove 13 provides an embedding space for the mounting base 22, allowing the seal 2 to be installed at the dust collection port 11 in a circumferentially positioned manner. After the mounting base 22 is embedded in the annular mounting groove 13, the mounting base 22 can form an abutment, clamping, or limiting fit with the groove wall of the annular mounting groove 13, thereby restricting the seal 2 from shifting or twisting relative to the dust collection port 11.
[0081] The elastic sealing part 21 protrudes from the mounting base 22 toward the mating side of the dust discharge port 105 and undergoes elastic compression when pressed against the dust discharge port 105. When the dust discharge port 105 repeatedly mates with and disengages from the base station 1, the force is preferentially transmitted to the elastic sealing part 21, and then the mounting base 22 and the annular mounting groove 13 bear the fixing reaction force. In this way, the seal 2 is not easily detached as a whole due to friction, squeezing or uneven load of the dust discharge port 105, nor is it easy for local warping to occur around the dust collection port 11.
[0082] The design of the annular mounting groove 13 also facilitates control over the installation height and posture of the seal 2 relative to the dust collection port 11. After the mounting base 22 is in place, the protrusion of the elastic sealing part 21 relative to the edge of the dust collection port 11 remains consistent, ensuring a more uniform compression state when the dust discharge port 105 presses against the elastic sealing part 21. Without the annular mounting groove 13, the seal 2 may only rely on surface bonding or partial snap-fit for fixation, which can easily lead to misalignment, deformation, or detachment after long-term pressure. By forming a circumferential constraint on the mounting base 22 through the annular mounting groove 13, the assembly reliability of the seal 2 can be improved, ensuring that the sealed connection between the dust discharge port 105 and the dust collection port 11 remains stable even after multiple connections.
[0083] In one exemplary embodiment, please refer to Figures 4 to 6As shown, the mounting base 22 is provided with a limiting rib 221, and the groove wall of the annular mounting groove 13 is provided with a limiting recess 14 that cooperates with the limiting rib 221. The limiting rib 221 is at least partially embedded in the limiting recess 14 to restrict the seal 2 from disengaging from the annular mounting part 12.
[0084] The mounting base 22 is provided with limiting ribs 221, and the groove wall of the annular mounting groove 13 is provided with limiting recesses 14 that cooperate with the limiting ribs 221. The limiting ribs 221 can be spaced apart circumferentially along the mounting base 22. The limiting recesses 14 are correspondingly provided on the inner groove wall of the annular mounting groove 13, so that after the mounting base 22 is embedded in the annular mounting groove 13, the limiting ribs 221 can at least partially enter the limiting recesses 14. Through the fitting relationship between the limiting ribs 221 and the limiting recesses 14, a limiting fit is formed between the seal 2 and the annular mounting part 12.
[0085] When assembling the seal 2, the mounting base 22 can be pressed into the annular mounting groove 13 under its own elastic deformation. The limiting rib 221 enters the limiting recess 14 through the opening of the annular mounting groove 13 and gets stuck in the limiting recess 14. After the limiting rib 221 and the limiting recess 14 are engaged, the movement of the mounting base 22 in the direction of disengaging from the annular mounting groove 13 will be restricted, and the seal 2 will not easily come off the annular mounting part 12.
[0086] The limiting rib 221 and the limiting recess 14 can also prevent the seal 2 from shifting or partially lifting within the annular mounting groove 13. When the dust discharge port 105 presses against the elastic sealing part 21, the force is transmitted to the mounting base 22 through the elastic sealing part 21. If the mounting base 22 lacks a reliable anti-detachment structure, the seal 2 may gradually loosen after long-term use, and the protruding position and pressure state of the elastic sealing part 21 will also change, resulting in unstable sealing contact between the dust discharge port 105 and the dust collection port 11. After the limiting rib 221 is embedded in the limiting recess 14, the mounting base 22 can be maintained in the predetermined position of the annular mounting groove 13, and the height and circumferential position of the elastic sealing part 21 relative to the dust collection port 11 are also more likely to remain consistent.
[0087] In one exemplary embodiment, please refer to Figures 4 to 6 As shown, the elastic sealing part 21 protrudes at least partially along the axial direction of the dust collection port 11 toward the dust discharge port 105, so that when the dust discharge port 105 presses against the sealing member 2, at least partially elastic compression occurs along the axial direction of the dust collection port 11.
[0088] The elastic sealing part 21 protrudes at least partially along the axial direction of the dust collection port 11 toward the dust discharge port 105, forming a predetermined protrusion height relative to the edge of the dust collection port 11. The axial direction of the dust collection port 11 can be understood as the main direction of airflow entering the base station 1 when the dust collection port 11 and the dust discharge port 105 are connected. After the elastic sealing part 21 protrudes along this direction, it can contact the dust discharge port 105 before the rigid edge of the dust collection port 11. When the stick vacuum cleaner 100 moves to the predetermined connection position, the dust discharge port 105 presses against the dust collection port 11. The dust discharge port 105 contacts the elastic sealing part 21 first and continues to apply pressure, causing the elastic sealing part 21 to undergo elastic compression at least partially along the axial direction of the dust collection port 11.
[0089] This protruding structure allows the seal 2 to actively meet the dust discharge port 105 with sufficient contact margin. If the elastic sealing part 21 is flush with the edge of the dust collection port 11, the dust discharge port 105 needs to be in a more precise position to form a compression seal, which places high demands on manufacturing tolerances and placement. After the elastic sealing part 21 protrudes towards the dust discharge port 105, even if there is a slight gap between the dust discharge port 105 and the dust collection port 11, the dust discharge port 105 can still press against the elastic sealing part 21 first. The elastic sealing part 21 compensates for this gap through axial compression, forming a continuous sealing contact and reducing air leakage channels caused by positional errors between rigid structures.
[0090] The elastic sealing part 21 is compressed along the axial direction of the dust collection port 11, which also helps to control the deformation direction of the seal 2. When the dust discharge port 105 presses against the seal 2, the force is mainly transmitted along the axial direction of the dust collection port 11, and the elastic sealing part 21 generates compression rebound in this direction, making the sealing contact force distribution more stable.
[0091] In one exemplary embodiment, please refer to Figure 4 and Figure 6 As shown, the elastic sealing part 21 includes an annular sealing lip 211, which protrudes toward the mating side of the dust discharge port 105 and surrounds the dust collection port 11 so as to fit the outer periphery of the dust discharge port 105 when it presses against the sealing member 2.
[0092] The annular sealing lip 211 serves as a flexible contact area near the dust outlet 105 within the elastic sealing portion 21. The annular sealing lip 211 protrudes towards the mating side of the dust outlet 105 and is arranged circumferentially around the dust collection port 11, forming a continuous lip seal structure around the periphery of the dust collection port 11. When the stick vacuum cleaner 100 docks with the base station 1, the dust outlet 105 gradually approaches the dust collection port 11. The outer periphery of the dust outlet 105 first contacts the annular sealing lip 211, and then applies pressure to the annular sealing lip 211. Under pressure, the annular sealing lip 211 can bend, compress, or adhere, thereby conforming to the outer periphery of the dust outlet 105.
[0093] The annular sealing lip 211 has a protruding structure, which improves the adaptability of the seal 2 to the shape of the outer periphery of the dust discharge port 105. The outer periphery of the dust discharge port 105 may have slight unevenness due to manufacturing errors, assembly errors, or wear during use. If only a flat seal is used, local gaps are likely to appear in the contact area. The annular sealing lip 211 has a thinner or more flexible lip structure, which can locally deform according to the actual shape of the outer periphery when pressed against the dust discharge port 105, so that the lip edge keeps fitting with the outer periphery, thereby forming a more continuous circumferential sealing boundary.
[0094] After the annular sealing lip 211 is installed around the dust collection port 11, the airflow channel between the dust discharge port 105 and the dust collection port 11 is surrounded by a flexible lip. When the base station 1 collects dust, the negative pressure mainly acts on the dust discharge port 105 and the interior of the dust chamber 104 through the dust collection port 11. The annular sealing lip 211 can prevent external air from entering from the gap between the outer periphery of the dust discharge port 105 and the dust collection port 11, and can also reduce the escape of fine dust from the dust chamber 104 from the mating gap. Since the annular sealing lip 211 and the outer periphery of the dust discharge port 105 are in flexible contact, the slight displacement of the dust discharge port 105 during the mating process is not likely to directly damage the sealing state.
[0095] In one exemplary embodiment, please refer to Figure 2 and Figure 3 As shown, the limiting structure 3 is provided with a first magnetic suction member 32, which is used to magnetically engage with the second magnetic suction member 102 on the main body rod 101 to keep the main body rod 101 in a predetermined docking position.
[0096] The limiting structure 3 is provided with a first magnetic attractor 32, which magnetically engages with a second magnetic attractor 102 on the main body rod 101. The first magnetic attractor 32 can be installed on the groove wall of the limiting groove 31 or located adjacent to the limiting groove 31, as long as its magnetic attraction area can cover the corresponding area after the main body rod 101 enters the predetermined docking position. The second magnetic attractor 102 can be a magnet, iron sheet, steel sheet, or other components that can be attracted by the first magnetic attractor 32. When the main body rod 101 moves along the limiting groove 31 to the predetermined docking position, the first magnetic attractor 32 and the second magnetic attractor 102 attract each other, so that the main body rod 101 is subjected to a holding force towards the limiting structure 3, thus making it difficult to detach from the predetermined docking position.
[0097] The limiting groove 31 restricts the movement path and posture of the main rod 101 through the groove wall, enabling the main rod 101 to enter the docking area in a preset direction. The first magnetic suction member 32 provides an attractive force when the main rod 101 approaches or reaches the predetermined docking position, so that the main rod 101 is stably held in the final docking position. The limiting groove 31 mainly serves as a guide and mechanical limiter, while the first magnetic suction member 32 mainly serves as a retainer and auxiliary locking member. When the two work together, the main rod 101, after entering the limiting groove 31, does not only rely on gravity or groove wall friction to maintain its position, but can also form a more stable docking state through magnetic attraction.
[0098] The first magnetic suction component 32 also enhances the user's sense of responsiveness during docking. When the main body rod 101 moves to the magnetic attraction area, the magnetic force guides the main body rod 101 closer to the final docking position, allowing the user to perceive the feedback of proper adsorption. This feedback helps reduce the need for the user to repeatedly adjust the position of the stick vacuum cleaner 100. After the main body rod 101 is stably held, the dust discharge port 105 can continuously press against the sealing component 2 towards the dust collection port 11. The sealing component 2 remains in an elastic compressed state, making the sealing connection between the dust discharge port 105 and the dust collection port 11 more stable. After the first magnetic suction component 32 and the limiting groove 31 jointly define the final docking position, the base station 1 is less prone to air or dust leakage due to body shaking during dust collection, making the negative pressure transmission and dust collection process more reliable.
[0099] In one exemplary embodiment, please refer to Figure 2 , Figure 4 and Figure 5 As shown, the substrate 10 is provided with a dust collection chamber and a dust collection channel 15 connected to the dust collection port 11. The dust collection channel 15 connects the dust collection port 11 and the dust collection chamber, and is used to transmit negative pressure to the dust discharge port 105 after the dust discharge port 105 is connected to the dust collection port 11.
[0100] The dust collection port 11 is used to receive dust and airflow from the exhaust port 105 after the stick vacuum cleaner 100 is docked in place. One end of the dust collection channel 15 is connected to the dust collection port 11, and the other end is connected to the dust collection chamber, so that the exhaust port 105, the dust collection port 11, the dust collection channel 15, and the dust collection chamber can form a connected dust collection path in the docked state. The dust collection chamber can be used to accommodate a dust bag, dust box, or other dust storage structure to receive dust discharged from the dust chamber 104 of the stick vacuum cleaner 100.
[0101] The dust collection channel 15 allows the negative pressure inside the base station 1 to be transmitted through the dust collection chamber to the dust collection port 11, and further acts on the dust discharge port 105 of the stick vacuum cleaner 100. After the dust discharge port 105 is connected to the dust collection port 11, the dust collection channel 15 not only undertakes the function of dust transportation, but also the function of negative pressure transmission. When the negative pressure source inside the base station 1 is working, a low-pressure area is formed in the dust collection chamber. The negative pressure is transmitted through the dust collection channel 15 to the dust collection port 11, generating a suction effect near the dust discharge port 105. Under the action of negative pressure, the dust in the dust chamber 104 enters the dust collection port 11 through the dust discharge port 105, and then enters the dust collection chamber along the dust collection channel 15.
[0102] The dust outlet 105 of the stick vacuum cleaner 100 is typically located in the docking area of the base station 1, while the dust collection chamber can be arranged in other locations inside the base 10 depending on the internal space of the base 10, the installation direction of the dust bag, and ease of maintenance. Connecting the dust outlet 11 and the dust collection chamber via the dust collection channel 15 allows the position of the dust outlet 11 to be adapted to the dust outlet 105 of the stick vacuum cleaner 100, while simultaneously placing the dust collection chamber in a location convenient for accommodating dust and replacing the dust bag. The dust collection channel 15 thus establishes an air passage connection between the docking position at the outlet and the internal dust storage space, avoiding the need for the dust collection chamber to be placed close to the dust outlet 105 and improving the flexibility of the internal space arrangement of the base 10.
[0103] In one exemplary embodiment, please refer to Figure 2 , Figure 4 and Figure 5 As shown, the base 10 has an clearance space 16 inside the dust collection port 11. The clearance space 16 is used to allow the dust chamber cover 106 of the stick vacuum cleaner 100 to extend at least partially when the dust chamber cover 106 is opened.
[0104] The clearance space 16 is located on the side of the dust collection port 11 facing away from the stick vacuum cleaner 100 and is arranged adjacent to the dust collection port 11. After the stick vacuum cleaner 100 is docked with the base station 1, the dust exhaust port 105 faces the dust collection port 11, and the dust cover 106 can deflect from the area where the dust exhaust port 105 is located into the base 10 during the opening process. The clearance space 16 is used to receive the part of the structure that enters the inner side of the base 10 after the dust cover 106 is opened, so that the dust cover 106 does not interfere with the base 10, the edge of the dust collection port 11, or the inlet of the dust collection channel 15 during the opening process.
[0105] When closed, the dust chamber cover 106 seals the dust outlet 105 to prevent dust from leaking from the dust outlet 105 during normal use or movement of the stick vacuum cleaner 100. When collecting dust at base station 1, the dust chamber cover 106 needs to be opened to expose the dust outlet 105 and connect it to the dust collection port 11. Since the dust outlet 105 and the dust collection port 11 are close to each other in the docked state, if there is insufficient space inside the base 10 to accommodate the dust chamber cover 106, the dust chamber cover 106 may not be able to open completely, or it may press against the inner wall of the base 10 during opening, resulting in insufficient opening area of the dust outlet 105 and affecting dust discharge.
[0106] The clearance space 16 can extend along the opening direction of the dust cover 106 and is adapted to the opening trajectory of the dust cover 106. When the dust cover 106 adopts a flip-opening method, the clearance space 16 can be set to correspond to the rotation radius of the dust cover 106. When the dust cover 106 adopts a sliding or swinging opening method, the clearance space 16 can be set to correspond to the sliding path or swing range of the dust cover 106. In this way, when the dust cover 106 is opened, it can at least partially extend into the clearance space 16, the effective opening area of the dust discharge port 105 is released, and dust can enter the dust collection port 11 through the dust discharge port 105.
[0107] Specifically, please refer to Figure 5 As shown, the clearance space 16 is provided with a cover limiting surface 17, which is used to limit the opening angle of the dust chamber cover 106 relative to the closed state to no more than 90°.
[0108] The cover limiting surface 17 is located on the movement path of the dust chamber cover 106 when it opens. It is used to abut or cooperate with the dust chamber cover 106 when it is opened to a predetermined angle relative to the closed state, thereby limiting the dust chamber cover 106 from further increasing the opening angle. The cover limiting surface 17 can be formed on the inner wall of the clearance space 16 or on the inner structure adjacent to the dust collection port 11. Its position corresponds to the opening trajectory of the dust chamber cover 106, so that the dust chamber cover 106 can be limited to a predetermined position after entering the clearance space 16.
[0109] The cover limiting surface 17 restricts the opening angle of the dust chamber cover 106 relative to the closed state to no more than 90°. This angle range is used to balance the opening area of the dust discharge port 105, the stability of the dust collection airflow, and the reliability of the docking seal. If the opening angle of the dust chamber cover 106 is too large, the dust chamber cover 106 may occupy the airflow space near the dust collection port 11, or even disrupt the fit between the dust discharge port 105 and the dust collection port 11, increasing the risk of dust spreading outward. By controlling the maximum opening angle of the dust chamber cover 106 through the cover limiting surface 17, the dust chamber cover 106 can remain within a relatively controllable space range while releasing the dust discharge port 105.
[0110] In summary, the base station and cleaning system provided in this disclosure, by setting a limiting structure on the base to cooperate with the main body of the stick vacuum cleaner, transforms the placement action of the stick vacuum cleaner into a docking action in which the dust discharge port presses against the dust collection port. When the main body moves along the limiting groove to the predetermined docking position, the posture of the stick vacuum cleaner is guided and limited by the limiting structure. The dust discharge port moves towards the dust collection port as the posture of the main body adjusts, and presses against the sealing element set at the dust collection port. The sealing element undergoes elastic deformation under the pressure of the dust discharge port, which can compensate for the slight deviation between the dust discharge port and the dust collection port, so that the dust discharge port and the dust collection port form a stable sealed connection.
[0111] It will be apparent to those skilled in the art that this disclosure is not limited to the details of the exemplary embodiments described above, and that this disclosure can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of this disclosure is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this disclosure. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0112] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
