Description

Technical Field

[0001] This utility model relates to the field of cleaning devices, and in particular to a portable base station vacuum cleaner. Background Technology

[0002] Vacuum cleaners come in various types, ranging from large to small, with structures such as T-shaped or 7-shaped. Apart from intelligent robotic vacuum cleaners, most handheld vacuum cleaners are operated by holding the vacuum cleaner in one's hand.

[0003] One type of handheld vacuum cleaner includes a handle and a main unit. The main unit is equipped with a fan, and the suction end of the fan has a dust cup. The main unit has a suction port corresponding to the suction end of the fan, and an exhaust port corresponding to the exhaust end of the fan. The suction port is connected to the dust cup. The dust cup usually contains a filter element, which is typically made of a material with micropores on its surface. When airflow passes through the dust cup, the filter element can intercept solid waste in the dust cup, thereby achieving solid waste collection. After the vacuum cleaner has been used for a long time, a lot of dust will be absorbed on the surface of the filter element. The dust will clog the micropores on the surface of the filter element, thereby weakening the suction power of the machine. Therefore, users need to replace the filter element regularly, which results in a significant operating cost for users.

[0004] Alternatively, users can clean the filter. To do this, the dust cup needs to be removed from the vacuum cleaner, the filter needs to be taken out of the dust cup, and then the filter and dust cup need to be put back into the vacuum cleaner after cleaning. This process is extremely cumbersome, and users will contaminate their hands and the surrounding environment when cleaning the filter, which will affect the user experience.

[0005] Secondly, there are handheld vacuum cleaners. When the dust cup is full, the user needs to remove the dust cup from the vacuum cleaner and then manually open the dust cup cover to remove the dust. This method of cleaning by directly contacting the dust cup is not only unhygienic, but also makes the cleaning process cumbersome.

[0006] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0007] In view of the above, this utility model addresses the deficiencies of the existing technology and its main objective is to provide a portable base station vacuum cleaner. This vacuum cleaner incorporates a dust-blowing cleaning mechanism directly within the space between the filter and the air intake. During cleaning, the cleaning air blown by this mechanism passes through the filter, blowing dust from its surface into the dust cup. This removes dust from the filter surface, reducing the frequency of manual filter disassembly and replacement, thus lowering operating costs. Furthermore, when the vacuum cleaner is connected to the dust collector base station, a trigger activates the dust cup cover, switching it from a closed to an open position, releasing dust from the dust cup into the dust collection chamber. This allows for easy cleaning and hygiene; simply insert the dust cup into the receiving chamber when cleaning is needed, eliminating the need to manually open the dust cup cover to empty it.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: A portable base station vacuum cleaner includes: A dust collector base station, wherein the dust collector base station is provided with a receiving cavity, a trigger element disposed in the receiving cavity, and a dust collection cavity that is connected vertically to the receiving cavity; A vacuum cleaner, which can be placed in a dust collector base station, includes a vacuum cleaner body, a dust cup, a filter element and a dust blowing and cleaning mechanism for blowing dust from the surface of the filter element into the dust cup. The vacuum cleaner body is provided with an air outlet and an air intake. The dust cup is located at the end of the vacuum cleaner away from the blowing cleaning mechanism. The end of the dust cup away from the blowing cleaning mechanism has an opening for vacuuming and emptying. A dust cup cover is provided inside the dust cup at the corresponding opening, and the dust cup cover can be switched between an open position and a closed position. The filter element is disposed inside the dust cup, and an installation space is formed between the filter element and the air inlet for the installation of the dust blowing cleaning mechanism. The dust blowing cleaning mechanism is disposed in the installation space and is in a clean state. In the cleaning state, the cleaning air blown out by the dust blowing cleaning mechanism passes through the filter element to blow the dust on the surface of the filter element into the dust cup; When the vacuum cleaner is docked with the dust collector base station, at least a portion of the dust cup is located in the receiving cavity, causing the trigger to switch the dust cup cover from the closed position to the open position, so that the dust in the dust cup is released into the dust collection cavity; When the vacuum cleaner is removed from the dust collector base station, the dust cup cover moves away from the trigger, so that the dust cup cover switches from the open position to the closed position.

[0009] As a preferred embodiment, the installation space is provided with an installation frame, and the installation frame is provided with several through-type air outlet channels; The dust-blowing cleaning mechanism includes a blower motor and fan blades. The blower motor is mounted on a mounting frame, and the fan blades are connected to the output end of the blower motor. The air outlet end of the fan blades corresponds to the air outlet channel. By setting a mounting frame with a through air outlet channel in the installation space and fixing the blower motor to the mounting frame and the air outlet end of the fan blades corresponding to the air outlet channel, on the one hand, the dust-blowing cleaning mechanism can be stably assembled through the mounting frame, avoiding shaking and displacement during the operation or movement of the vacuum cleaner, thus improving structural reliability. On the other hand, the air outlet channel can directionally guide the cleaning air blown out by the fan blades, ensuring that the cleaning air concentrates through the filter element, enhancing the blowing force and efficiency of dust and impurities on the surface of the filter element, and improving the cleaning effect of the filter element.

[0010] As a preferred embodiment, the vacuum cleaner body is further provided with a suction component, a first control component for controlling the start and stop of the suction component, and a second control component for controlling the start and stop of the dust blowing cleaning mechanism. The first control component is electrically connected to the suction component, and the second control component is electrically connected to the dust blowing cleaning mechanism. By setting independent first and second control components to control the start and stop of the suction component and the dust blowing cleaning mechanism respectively, independent control of their functions can be achieved. This avoids interference between the suction component and the dust blowing cleaning mechanism, and allows users to flexibly choose the start time according to actual needs (such as starting the dust blowing cleaning mechanism only when cleaning the filter, without linking other blowing functions), improving operational flexibility and functional adaptability.

[0011] As a preferred embodiment, the cavity is further provided with conductive contacts, and the vacuum cleaner body is also provided with matching metal contacts at the corresponding positions of the conductive contacts. When the vacuum cleaner body is connected to the dust collector base station, the conductive contacts and the metal contacts fit together to form a conductive circuit. The conductive contacts and the matching metal contacts cooperate to achieve a tight fit through elastic deformation when the vacuum cleaner body and the dust collector base station are connected, ensuring stable conduction of the conductive circuit and guaranteeing the reliability of power transmission (such as charging) or signal communication between the two.

[0012] As a preferred embodiment, a positioning groove is also provided on the inner wall of the receiving cavity. The positioning groove is located next to the conductive contact. The dust cup is also provided with a positioning protrusion on the outside for matching the positioning groove. When the dust cup is placed in the receiving cavity, the positioning protrusion and the positioning groove cooperate. The positioning groove on the inner wall of the receiving cavity and the positioning protrusion on the outside of the dust cup form a precise fit, which can limit and fix the installation position of the dust cup in the receiving cavity, prevent the dust cup from shaking due to the movement of the vacuum cleaner or the operation of the base station, ensure the relative position stability of the dust cup and other components in the receiving cavity (such as conductive contacts and dust inlet channels), avoid electrical connection failure or dust leakage caused by misalignment, and improve the overall assembly stability and functional reliability.

[0013] As a preferred embodiment, an annular positioning part is provided at the end of the dust cup near the blower motor. A filter cartridge support is provided inside the dust cup, with one end of the filter cartridge support abutting against the annular positioning part. A filter screen is provided on the outer wall of the filter cartridge support, and the filter element is located inside the filter cartridge support. The annular positioning part provides stable support for the filter cartridge support, ensuring that its installation position inside the dust cup is fixed, and preventing the filter cartridge support from shifting due to vacuum cleaner vibration, which would affect the filtration effect. The filter screen on the outside of the filter cartridge support and the filter element inside form a multi-stage filtration structure, which can first intercept larger particulate impurities through the filter screen, and then filter fine dust through the filter element, improving the overall filtration efficiency and reducing the clogging speed caused by the filter element bearing the filtration load alone.

[0014] As a preferred embodiment, an abutment is provided on the side of the opening, and a through hole is provided on the abutment; the dust cup cover includes a sealing part and an abutment extending from one end of the sealing part, and a positioning element is provided on the abutment; When the dust cup cover is switched from the closed position to the open position, the positioning member moves away from the through hole, and the abutting part moves away from the abutting position, so that the sealing part moves away from the opening. When the dust cup cover is switched from the open position to the closed position, the positioning member is located in the through hole, and the abutting part abuts against the abutting position, so that the sealing part blocks the opening. When closed, the positioning member is inserted into the through hole and the abutting part tightly abuts against the abutting position, which can ensure that the sealing part firmly blocks the opening and effectively prevents dust in the dust cup from leaking from the opening. When opened, the positioning member is disengaged from the through hole and the abutting part is moved away from the abutting position, which can realize the smooth opening of the opening, which is convenient for emptying dust or maintenance of internal components.

[0015] As a preferred embodiment, the dust collection chamber has a dust collection port, and the receiving chamber has a dust inlet channel connected to the dust collection port. When the dust cup is docked with the dust collector base station, the outlet of the dust cup is located inside the dust collection port. When the dust cup is docked with the dust collection base station, the outlet of the dust cup is located inside the dust collection port and is connected to the dust collection chamber through the dust inlet channel, which can form a closed dust dumping path. During the dust dumping process, the dust in the dust cup can directly enter the dust collection chamber through the dust inlet channel, avoiding dust leakage to the outside of the base station due to docking gaps, thus improving dust collection efficiency and cleanliness. At the same time, precise alignment and matching reduce dust residue during transmission.

[0016] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly sets up a dust blowing and cleaning mechanism in the installation space between the filter element and the air inlet. In this way, when cleaning, the cleaning air blown out by the dust blowing and cleaning mechanism passes through the filter element to blow the dust on the surface of the filter element into the dust cup, thereby removing the dust on the surface of the filter element, reducing the frequency of manual disassembly and cleaning of the filter element, as well as the frequency of replacing the filter element, and reducing the cost of use. Secondly, when the vacuum cleaner is connected to the dust collector base station, the trigger causes the dust cup cover to switch from the closed position to the open position, releasing the dust in the dust cup into the dust collection chamber. Thus, when it is necessary to clean the dust in the dust cup body, the dust cup can be inserted into the receiving chamber without manually opening the dust cup cover to empty the dust in the dust cup body. This is convenient and more hygienic.

[0020] Please refer to Figures 1 to 7 As shown, it illustrates the specific structure of an embodiment of the present invention.

[0021] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] A portable base station vacuum cleaner includes a dust collector base station 10 and a vacuum cleaner 20.

[0023] The dust collector base station 10 is provided with a receiving cavity 11, a trigger 12 disposed in the receiving cavity 11, and a dust collection cavity 13 that is vertically connected to the receiving cavity 11; Preferably, a conductive contact 111 is further provided inside the receiving cavity 11. Preferably, a positioning groove 112 is further provided on the inner sidewall of the receiving cavity 11, and the positioning groove 112 is located beside the conductive contact 111. The dust collector base station 10 is also equipped with a charging management module (including a transformer, rectifier circuit, and protection chip). The conductive contact 111 is connected to the charging management module inside the base station via a wire, converting the mains power (220V AC) into low-voltage DC power suitable for the vacuum cleaner 20 battery. When the vacuum cleaner 20 is fully returned to its original position, the elastic contact on the side of the dust collector base station 10 is squeezed by the outer shell of the vacuum cleaner 20, compressing the spring and extending forward to fit tightly with the contact on the side of the vacuum cleaner 20. At this time, the low-voltage DC power on the side of the dust collector base station 10 forms a closed conductive circuit through the base station contact, the vacuum cleaner 20 contact, and the battery protection board. This charging method is a well-known technology in the field.

[0024] Preferably, the dust collection chamber 13 has a dust collection port 131, and the receiving chamber 11 has a dust inlet channel 113 connected to the dust collection port 131. When the dust cup 22 is docked with the dust collector base station 10, the outlet of the dust cup 22 is located inside the dust collection port 131. When the dust cup 22 is docked with the dust collection base station, the outlet of the dust cup 22 is located inside the dust collection port 131 and is connected to the dust collection chamber 13 through the dust inlet channel 113, which can form a closed dust dumping path. During the dust dumping process, the dust in the dust cup 22 can directly enter the dust collection chamber 13 through the dust inlet channel 113, avoiding dust leakage to the outside of the base station due to the docking gap, thus improving dust collection efficiency and cleanliness. At the same time, the precise alignment reduces dust residue during the transmission process.

[0025] The vacuum cleaner 20 is removably mounted in the dust collector base station 10. The vacuum cleaner 20 includes a vacuum cleaner body 21, a dust cup 22, a filter element 23, and a dust blowing and cleaning mechanism 24 for blowing dust from the surface of the filter element 23 into the dust cup 22.

[0026] The vacuum cleaner body 21 is provided with an air outlet 211 and an air inlet 212; the vacuum cleaner body 21 is also provided with a matching metal contact 213 at the corresponding conductive contact 111. When the vacuum cleaner body 21 is connected to the dust collector base station 10, the conductive contact 111 and the metal contact 213 are attached to form a conductive circuit. The conductive contact 111 and the matching metal contact 213 cooperate to achieve a tight fit through elastic deformation when the vacuum cleaner body 21 is connected to the dust collector base station, ensuring stable conduction of the conductive circuit and ensuring the reliability of power transmission (such as charging) or signal communication between the two.

[0027] The dust cup 22 is located at the end of the vacuum cleaner 20 away from the blowing cleaning mechanism 24. The end of the dust cup 22 away from the blowing cleaning mechanism 24 is provided with an opening 221 for vacuuming and emptying. A dust cup cover 25 is provided in the dust cup 22 corresponding to the opening 221, and the dust cup cover 25 can be switched between an open position and a closed position. Preferably, an abutment position 222 is provided on the side of the opening 221, and a through hole 223 is provided on the abutment position 222; the dust cup cover 25 includes a sealing part 251 and an abutment part 252 extending from one end of the sealing part 251, and a positioning element is provided on the abutment part 252; When the dust cup cover 25 is switched from the closed position to the open position, the positioning member moves away from the through hole 223, and the abutting part 252 moves away from the abutting position 222, so that the sealing part moves away from the opening 221. When the dust cup cover 25 is switched from the open position to the closed position, the positioning member is located in the through hole 223, and the abutting part 252 abuts against the abutting position 222, so that the sealing part blocks the opening 221. When closed, the positioning member is inserted into the through hole 223 and the abutting part 252 tightly abuts against the abutting position 222, which can ensure that the sealing part 251 firmly blocks the opening 221 and effectively prevents dust in the dust cup 22 from leaking from the opening 221. When opened, the positioning member is disengaged from the through hole 223 and the abutting part 252 is moved away from the abutting position 222, which can realize the smooth opening of the opening 221, which is convenient for emptying dust or maintenance of internal components.

[0028] The filter element 23 is disposed in the dust cup 22, and an installation space 26 for the dust blowing cleaning mechanism 24 is formed between the filter element 23 and the air intake 212. Preferably, an installation frame 27 is disposed in the installation space 26, and a plurality of through-type air outlet channels 271 are disposed on the installation frame 27. The dust blowing cleaning mechanism 24 is installed in the installation space 26. The dust blowing cleaning mechanism 24 has a cleaning state. In the cleaning state, the cleaning air blown out by the dust blowing cleaning mechanism 24 passes through the filter element 23 to blow the dust on the surface of the filter element 23 into the dust cup 22. The dust-blowing cleaning mechanism 24 includes a blower motor 241 and a fan blade 242. The blower motor 241 is mounted on a mounting frame 27, and the fan blade 242 is connected to the output end of the blower motor 241. The air outlet end of the fan blade 242 is set to correspond to the air outlet channel 271. By setting a mounting frame 27 with a through air outlet channel 271 in the installation space 26, and fixing the blower motor 241 to the mounting frame 27 and the air outlet end of the fan blade 242 to correspond to the air outlet channel 271, on the one hand, the dust-blowing cleaning mechanism 24 can be stably assembled through the mounting frame 27, avoiding it from shaking or shifting during the operation or movement of the vacuum cleaner 20, thus improving structural reliability; on the other hand, the air outlet channel 271 can directionally guide the cleaning air blown out by the fan blade 242, ensuring that the cleaning air concentrates through the filter element 23, enhancing the blowing force and efficiency of dust and impurities on the surface of the filter element 23, and improving the cleaning effect of the filter element 23.

[0029] The blower motor 241 is directly built into the installation space 26, blowing outwards from the inner surface of the filter element 23, thereby cleaning all areas of the filter element 23 and blowing off the dust adhering to its surface. The blower motor 241 operates after the dust collection action is completed to avoid mutual interference. When the suction assembly 214 is suctioning, the air entering the filter element 23 enters the installation space 26, flows upwards through the air duct in the blower motor 241, and finally enters the main unit, and is discharged from the air outlet 211.

[0030] The mounting space 26 formed between the filter element 23 and the air intake 212 of the vacuum cleaner body 21 is a sealed space, allowing gas to pass only through the filter element 23. During self-cleaning, the air blown by the blower motor 241 can only be blown from the inner surface of the filter element 23 and outwards. The sealing structure of the channel can be formed by directly attaching the filter element 23 to the vacuum cleaner body 21, or by using a connector to connect the filter element 23 and the vacuum cleaner body 21.

[0031] When the vacuum cleaner 20 is docked with the dust collector base station 10, at least a portion of the dust cup 22 is located in the receiving cavity 11, causing the trigger 12 to trigger the dust cup cover 25 to switch from the closed position to the open position, so that the dust in the dust cup 22 is released into the dust collection cavity 13. When the vacuum cleaner 20 is removed from the dust collector base station 10, the dust cup cover 25 moves away from the trigger 12, so that the dust cup cover 25 switches from the open position to the closed position.

[0032] Preferably, the vacuum cleaner body 21 is further provided with a suction component 214, a first control component 215 for controlling the start and stop of the suction component 214, and a second control component 216 for controlling the start and stop of the dust blowing cleaning mechanism 24. The first control component 215 is electrically connected to the suction component 214, and the second control component 216 is electrically connected to the dust blowing cleaning mechanism 24. The independent first control component 215 and the second control component 216 control the start and stop of the suction component 214 and the dust blowing cleaning mechanism 24 respectively, which can realize the independent control of the functions of the two: it avoids interference between the suction component 214 and the dust blowing cleaning mechanism 24, and allows users to flexibly choose the start time according to actual needs (such as starting the dust blowing cleaning mechanism 24 alone when only the filter element 23 needs to be cleaned, without linking other blowing functions), improving operational flexibility and functional adaptability.

[0033] When the vacuum cleaner 20 is removed from the dust collection base for vacuuming, the suction component 214 draws in air, creating a vacuum negative pressure environment in the dust cup 22. This controls the dust cup cover 25 to switch from the closed position to the open position, allowing external airflow to be drawn in. The airflow enters the dust cup 22 from the inlet and then enters the filter element 23. The filter element 23 can intercept solid waste carried in the airflow in the dust cup 22, thereby achieving waste collection.

[0034] The dust cup 22 is also provided with a positioning protrusion 224 for matching the positioning groove 112. When the dust cup 22 is placed in the receiving cavity 11, the positioning protrusion 224 cooperates with the positioning groove 112. The positioning groove 112 on the inner side wall of the receiving cavity 11 and the positioning protrusion 224 on the outside of the dust cup 22 form a precise fit, which can limit and fix the installation position of the dust cup 22 in the receiving cavity 11, prevent the dust cup 22 from shaking due to the movement of the vacuum cleaner 20 or the operation of the base station, ensure the relative position of the dust cup 22 and other components (such as the conductive contact 111 and the dust inlet channel 113) in the receiving cavity 11 is stable, avoid electrical connection failure or dust leakage caused by misalignment, and improve the overall assembly stability and functional reliability.

[0035] Preferably, an annular positioning part 225 is provided at one end of the dust cup 22 near the blower motor 241. A filter cartridge support 226 is provided inside the dust cup 22, with one end of the filter cartridge support 226 abutting against the annular positioning part 225. A filter screen 227 is provided on the outer wall of the filter cartridge support 226, and the filter element 23 is located inside the filter cartridge support 226. The annular positioning part 225 provides stable support for the filter cartridge support 226, ensuring that its installation position inside the dust cup 22 is fixed, and avoiding displacement of the filter cartridge support 226 due to vibration of the vacuum cleaner 20, which would affect the filtration effect. The filter screen 227 on the outside of the filter cartridge support 226 and the filter element 23 inside form a multi-stage filtration structure. Larger particulate impurities can be intercepted first through the filter screen 227, and then fine dust can be filtered through the filter element 23, improving the overall filtration efficiency and reducing the clogging speed caused by the filter element 23 bearing the filtration load alone.

[0036] The key design feature of this utility model is that it mainly sets up a dust-blowing cleaning mechanism in the installation space between the filter element and the air inlet. In this way, when cleaning, the cleaning air blown out by the dust-blowing cleaning mechanism passes through the filter element and blows the dust on the surface of the filter element into the dust cup, thereby removing the dust on the surface of the filter element, reducing the frequency of manual disassembly and cleaning of the filter element, as well as the frequency of replacing the filter element, and reducing the cost of use. Secondly, when the vacuum cleaner is connected to the dust collector base station, the trigger causes the dust cup cover to switch from the closed position to the open position, releasing the dust in the dust cup into the dust collection chamber. Thus, when it is necessary to clean the dust in the dust cup body, the dust cup can be inserted into the receiving chamber without manually opening the dust cup cover to empty the dust in the dust cup body. This is convenient and more hygienic.

[0037] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
