Technical Field

[0001] This utility model relates to the field of vacuum cleaner technology, and in particular to an upright vacuum cleaner. Background Technology

[0002] With the development of the times and the improvement of living standards, vacuuming equipment, especially household vacuum cleaners, has been widely used. A vacuum cleaner is an electrical appliance that uses an electric motor (suction motor / vacuum motor) to generate negative air pressure in a sealed casing to suck up dust or debris.

[0003] Chinese Patent Authorization Announcement No.: CN 208988696 U, Authorization Announcement Date: June 18, 2019. This utility model proposes an upright vacuum cleaner, including a dust cylinder, an upper base, a vacuum motor, a filter cartridge, and multiple bottom wheels. An air inlet pipe is provided on the side wall of the dust cylinder. A motor cavity is provided inside the dust cylinder, and the vacuum motor is located within the motor cavity, communicating with the interior of the dust cylinder. The communication between the motor cavity and the interior of the dust cylinder is separated by the filter cartridge. An exhaust port communicating with the motor cavity is provided on the upper base, with the exhaust end of the vacuum motor facing the exhaust port and the inlet end of the vacuum motor facing the dust cylinder. A sponge tube is provided inside the filter cartridge, with the outer wall of the sponge tube contacting the inner wall of the filter cartridge. The shortcomings of this technical solution are: 1. Insufficient assembly stability and efficiency of later disassembly and maintenance, resulting in reduced convenience and shortened service life during use; 2. Insufficient heat dissipation efficiency of the vacuum motor, making continuous operation difficult for large-capacity vacuum cleaners.

[0004] In summary, vacuum cleaners suffer from poor assembly and maintenance stability and efficiency, as well as low heat dissipation. Utility Model Content

[0005] The present invention aims to overcome the shortcomings of existing vacuum cleaners, such as poor assembly and maintenance stability and efficiency, and low heat dissipation intensity, and provides an upright vacuum cleaner that improves assembly efficiency and stability and enhances heat dissipation efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An upright vacuum cleaner, including

[0008] Dust collection box, with wheels attached;

[0009] Mounting base, which is detachably connected to the dust collection box. The mounting base is equipped with an air inlet that is connected to the inner cavity of the dust collection box.

[0010] The ventilation mesh frame is connected to the mounting base. A dust filter cup assembly is detachably connected to one side of the ventilation mesh frame, and a vacuum motor is detachably connected to the other side of the ventilation mesh frame.

[0011] Connecting components are connected to the mounting base;

[0012] The motor cover is detachably connected to the mounting base via a connecting component. The motor cover is sleeved with the vacuum motor. The motor cover is provided with an air outlet, and the mounting base is provided with an air outlet channel. The air outlet and the air outlet channel are connected.

[0013] The box cover is detachably connected to the mounting base via a connecting assembly. Both the motor cover and the box cover are equipped with heat dissipation vents. Both the mounting base and the motor cover are connected to dustproof components. The box cover is rotatably connected to a handle.

[0014] The dust collection box is a box-shaped structure with one end open and the other end connected to wheels. It is used for collecting and placing garbage and debris. The box design increases the vacuum cleaner's capacity and facilitates mobility. A mounting base is connected to the open end of the dust collection box, allowing connection to the motorized part. The mounting base and dust collection box are directly and detachably connected for quick separation and easy assembly. This facilitates disassembly during parts production and cleaning. An air inlet is located on the mounting base, connecting to a pipe that sucks in garbage and debris, allowing it to be collected inside the dust collection box. A ventilation frame separates the dust cup assembly and the vacuum motor, arranging them vertically opposite each other. The ventilation frame supports and positions the dust cup assembly and vacuum motor, ensuring a stable and precise connection. This allows the vacuum motor to create negative pressure suction inside the dust collection box, collecting garbage and debris through the air inlet. The dust cup assembly separates the gas and garbage, and the separated gas is then passed through... The air outlet of the mounting base sends air out through the air outlet on the motor cover. This achieves the dust removal process where the vacuum cleaner motor drives the air in through the air inlet, and after air-to-debris separation by the dust cup assembly, the air exits through the air outlet. The cover connects to the motor cover and mounting base to protect the vacuum cleaner motor inside. A handle allows for easy portability of the entire vacuum cleaner. Both the cover and motor cover have ventilation holes to dissipate heat from the motor. Dust-blocking components are also connected to both the mounting base and motor cover to prevent external dust and debris from entering the interior and affecting motor performance, ensuring sufficient cleaning time and extending the vacuum cleaner's lifespan. The motor cover and cover are detachably connected to the mounting base via connecting components, allowing for efficient assembly and convenient disassembly for easy maintenance. This achieves the effects of increasing the vacuum cleaner's cleaning capacity, improving the assembly efficiency of vacuum cleaner accessories, facilitating disassembly and maintenance, enabling easy portability, enhancing heat dissipation and dust prevention, and extending cleaning time and lifespan.

[0015] Preferably, the mounting base is connected with a buckle, the dust collection box is connected with a buckle plate, the buckle has buckle holes, the buckle is engaged with the buckle plate through the buckle holes, the buckle plate is connected with several reinforcing ribs, the reinforcing ribs are connected to the dust collection box, the buckle is connected with guide ribs, the guide ribs are connected to the mounting base, the buckle plate and the guide ribs are slidably connected, the mounting base has a mating groove, and the dust collection box is inserted into the mating groove. The mounting base engages with the dust collection box's snap-fit ​​plate via snap-fit ​​holes, allowing for quick connection and separation. Several reinforcing ribs on the snap-fit ​​plate ensure stable attachment to the dust collection box, enhancing structural strength to withstand frequent opening and reconnection during waste removal. Guide ribs connect the snap-fit ​​plate to both sides, improving the overall integrity and structural strength of the connection, further supporting frequent operation. During connection, the snap-fit ​​plate can quickly connect to the snap-fit ​​plate along the guide ribs, improving connection accuracy and efficiency. A recessed mating groove at the lower end of the mounting base allows for interlocking with the dust collection box, enhancing the stability and sealing of the connection. This design achieves the following effects: improved efficiency in emptying and reconnecting the vacuum cleaner; high structural strength to prevent breakage; directional operation for enhanced connection accuracy; and improved structural stability and sealing.

[0016] Preferably, the lower end face of the mounting base has a mounting cavity, and the side of the mounting base has a mounting groove that communicates with the mounting cavity. The mounting groove is connected to an air inlet, which is also connected to the mounting cavity. A baffle plate is connected to the mounting cavity, positioned on one side of the mounting groove and opposite to the air inlet. The lower end face of the mounting base (facing the dust collection box) is a recessed mounting cavity. The mounting groove is located on the upper side of the mounting base and communicates with the mounting cavity, connecting the air inlet connected within the mounting groove to the mounting cavity. The mounting cavity is connected to the dust collection chamber. One end of the air inlet is used to connect to a pipe for collecting debris. Simultaneously, a curved baffle plate is connected to the bottom of the mounting cavity, opposite to the other end of the air inlet. This allows debris to be guided into the dust collection chamber by the baffle plate when it is sucked in, reducing airflow force and making it easier for debris to be collected and contact the filter cup assembly. This improves the ease of use and structural connection strength of the vacuum cleaner.

[0017] Preferably, the mounting base has a mounting hole 1, which is connected to an air guide tube. The ventilation mesh frame is connected to the air guide tube, and the air guide tube is connected to a reinforcing rib plate 2, which is connected to the cavity wall of the mounting cavity. One end of the air guide tube is open, and the other end of the air guide tube is connected to a base plate. The base plate is inserted into a mounting cylinder, and the lower end of the mounting cylinder is connected to a dust collection motor. The dust filter cup assembly includes a filter cup and a fixed cup. Several support plates are connected to the inner wall of the filter cup. The fixed cup is inserted into the filter cup through the support plates. The filter cup has filter holes, and an air inlet channel is provided in the gap between the support plates. The filter holes are connected to the air inlet channel. The filter cup is connected to a limit strip, and the lower end of the mounting cylinder has a limit hole and a guide groove. The limit strip is slidably connected to the guide groove and snapped into the limit hole. The mounting base connects to the air duct via mounting hole one. The air duct, connected to the mounting base, sinks deep into the dust collection box, increasing the contact area between the dust cup assembly connected to the mounting tube and the debris, thus improving filtration efficiency. Reinforcing rib two connects the mounting base and the air duct, enhancing the structural strength of the air duct and its overall integrity with the mounting base. The upper end of the air duct is open, and the lower end is connected to a base plate for fixing the mounting tube. The filter in the dust cup assembly is secured by a limiting strip that engages with the limiting hole on the mounting tube. The guide groove on the cylinder guides the limiting strip, enabling quick connection of the limiting strip and preventing repeated alignment of the filter cup during connection. The fixing cup is used to fix the mesh opening of the filter screen outside the filter cup to the filter cup. The filter screen is sleeved on the outside of the filter cup, with the mesh opening inserted into the filter cup opening, and the mesh opening is fixed by pressing it into the fixing cup. The filter screen is placed between the support plate and the fixing cup and pressed together to prevent the filter screen from moving. At the same time, the gap between the support plates allows gas to pass through and flow upward from the ventilation frame through the gap between the dust cup assembly and the ventilation frame. This achieves the effects of improving the structural connection strength and integrity, improving the structural assembly efficiency and accuracy, and facilitating quick replacement and maintenance.

[0018] Preferably, the ventilation frame includes a connecting cylinder, a ventilation mesh plate, and reinforcing ribs. The ventilation mesh plate is connected to the inner wall of the mounting cylinder, and the reinforcing ribs are connected to the wall of the mounting cylinder and the ventilation mesh plate. The ventilation mesh plate has several ventilation holes. The connecting cylinder is connected to the ventilation mesh plate, and the ventilation holes are located inside the connecting cylinder. The fixed cup is arranged vertically opposite to the connecting cylinder, and the inner diameter of the fixed cup is larger than the inner diameter of the connecting cylinder. The ventilation mesh plate in the ventilation frame isolates the dust filter cup assembly from the vacuum cleaner motor from the inner wall of the mounting cylinder. The ventilation mesh plate has several ventilation holes and is located inside the connecting cylinder connected to the ventilation mesh plate. The central axis of the connecting cylinder and the fixed cup are aligned, and their ports are arranged opposite each other. The inner diameter of the fixed cup is larger than the inner diameter of the connecting cylinder. This allows airflow to flow upward between the filter cup support plates, then laterally enter between the connecting cylinder and the fixed cup, and finally flow out through the ventilation holes of the connecting cylinder and the ventilation mesh plate, thereby weakening the airflow force and reducing the noise inside the vacuum cleaner. This achieves the effect of improving the connection strength between structures and reducing operating noise through structural design.

[0019] Preferably, the air outlet channel is the gap between the upper end of the mounting cylinder and the air guide cylinder. A guide plate is connected to the bottom plate, and the gap between the guide plate and the cylinder wall of the air guide cylinder connects to the air outlet channel. The motor cover is connected to the air outlet, which is connected to the air outlet and the air outlet channel. A reinforcing rib four is connected to the air outlet and is also connected to the air outlet. The upper end of the air guide cylinder extends from the bottom plate and connects to the lower end of the vacuum motor, forming a ring-shaped air outlet channel with the vacuum motor. This allows the airflow from the vacuum motor to enter the air outlet channel. A curved guide plate is connected inside the guide cylinder to guide the airflow cup between the guide plate and the guide cylinder, allowing it to enter the air outlet of the motor cover and then exit. The airflow forms an upward vortex through the air outlet channel and flows smoothly out of the air outlet channel. The reinforcing rib four strengthens the connection between the air outlet channel and the motor cover. This achieves a stable structural connection and smooth airflow.

[0020] Preferably, the motor cover includes a docking base plate, a protective shell, and a supporting top plate. The air outlet is connected to the docking base plate, which has a mounting protrusion and a docking groove. The air outlet is inserted into the docking groove. The protective shell is connected to the docking base plate. One end of the vacuum cleaner motor abuts against the upper port of the mounting cylinder, and the other end of the vacuum cleaner motor is inserted into the protective shell. The supporting top plate is perpendicularly connected to the protective shell and the docking base plate. The cover is connected to a guide plate, and the protective shell and the supporting top plate are slidably connected to the guide plate. The mating base plate in the motor housing connects to the mounting base and supports the protective shell, air outlet, and top support plate. The mounting protrusion on the lower surface of the mating base plate connects to the air duct via a mating groove, enabling quick and precise positioning of the vacuum cleaner motor and the air duct. The protective shell's shape is adapted to the vacuum cleaner motor's shape to house and protect it, and works with the mounting cylinder to prevent motor movement. The top support plate vertically connects the protective shell and the mating base plate, improving the overall strength of the motor housing. Simultaneously, the guide plate on the cover abuts against the top support plate, supporting and guiding the connection of the cover. This achieves the effect of improving the connection efficiency between structures, positioning accuracy, and the overall strength of the vacuum cleaner.

[0021] Preferably, the upper surface of the protective shell is connected to a heat dissipation mesh plate with several heat dissipation holes. The supporting top plate has a ventilation notch, and the guide insert has a positioning groove. The motor cover is inserted into the positioning groove, and the groove wall has a flow port. The heat dissipation holes connect the inner cavity of the protective shell, the ventilation notch, and the flow port. The upper surface of the protective shell dissipates heat from the vacuum cleaner motor through the heat dissipation holes on the heat dissipation mesh plate. The guide insert forms a positioning groove with a notch in the groove wall, allowing the port of the protective shell to be inserted. The notch in the positioning groove serves as a flow port, and the ventilation notch of the supporting top plate connects the heat dissipation holes and the flow port, allowing the top of the vacuum cleaner motor to still dissipate heat through the flow port. This enhances heat dissipation, thereby extending the operating time and service life of the vacuum cleaner.

[0022] Preferably, the heat dissipation vents include a cover heat dissipation vent and a protective shell heat dissipation vent. The protective shell heat dissipation vent is placed on the protective shell and arranged opposite to the flow port on both sides with the dust collection motor as the center. The cover heat dissipation vents are placed on both sides of the cover. The dust blocking assembly includes a dust blocking seat and a dustproof frame. The dustproof frame is connected to the mounting base, the dust blocking seat is connected to the docking base plate, the dustproof frame is connected to several dustproof fins, the dust blocking seat is connected to a baffle plate, the baffle plate is placed between the dustproof fins and the protective shell heat dissipation vents, and the cover heat dissipation vent is connected to a positioning frame, which is engaged with the dustproof frame. The heat dissipation vents include a vent on the lid and a vent on the side of the protective shell. Both vents are arranged opposite the flow outlet on both sides, centered on the dustproof motor. This allows the vacuum cleaner to dissipate heat from both sides, increasing the number of heat dissipation points. The flow outlet connects the two heat dissipation shells to each other, improving heat dissipation efficiency. The dustproof assembly includes two dustproof frames arranged opposite each other. The vents on both sides of the lid are connected to the dustproof frames via positioning frames. One side's support plate and dustproof insert prevent dust and debris from entering the flow outlet through the gaps in the dustproof fins on that side. The other side's dustproof seat has a baffle to prevent dust and debris from entering the protective shell heat dissipation vent through the gaps in the dustproof fins on that side. This enhances both the heat dissipation and dustproofing effects of the vacuum cleaner.

[0023] Preferably, the connecting assembly includes several inserts and fixing posts, both of which are connected to the mounting base. A positioning seat is connected to the mating base plate, and a connecting post is connected to the cover. The positioning seat has a first insertion hole, into which the insert is inserted. The fixing post has a slot, into which the connecting post is inserted. The slot has a second insertion hole, into which a fixing screw is inserted. The connecting post has a connecting screw hole, into which the fixing screw is threaded. The inserts and fixing posts in the connecting assembly are connected to the mounting base. The mating base plate of the motor cover is connected to the positioning seat. The positioning seat, through the connection of the first insertion hole to the insert, positions the motor cover on the mounting base. When connecting the cover, the connecting post is inserted into the slot on the fixing post to position it on the mounting base. The fixing screw, through the connection of the connecting screw hole, secures the cover to the mounting base and clamps the motor cover in the middle. Simultaneously, the fixing screw allows for quick separation of the three structures for later maintenance. This achieves the effect of improving structural connection efficiency and stability while facilitating later disassembly and maintenance.

[0024] The beneficial effects of this utility model are: increasing the cleaning capacity of the vacuum cleaner; improving the assembly efficiency of vacuum cleaner accessories; facilitating disassembly and maintenance, and making it easy to move and use; enhancing heat dissipation and dustproof effect; extending cleaning time and service life; improving the operational efficiency of emptying and reconnecting the vacuum cleaner; ensuring high connection strength between structures and preventing breakage; providing directional operation and improving connection accuracy; improving the stability and sealing of connections between structures; reducing operating noise through structural design; and improving the positioning accuracy of connections between structures and the overall strength of the vacuum cleaner.
