Description

Technical Field

[0001] This invention relates to the field of vacuum cleaner technology, specifically a multi-module quick-release vacuum cleaner. Background Technology

[0002] Existing vacuum cleaners, especially handheld or stick vacuum cleaners, typically use a one-piece molded main body or are fastened together with multiple scattered screws. While this structure ensures the stability of the entire machine, maintaining internal components (such as the air intake structure, circuit board, battery pack, or charging dock) often requires disassembling numerous screws one by one, sometimes even damaging the housing clips. This is cumbersome and prone to damaging the housing. Furthermore, the connection between the battery pack and the circuit board is often a fixed wiring harness or a hard plug, which cannot be automatically separated or connected when disassembling or assembling the main body, increasing maintenance difficulty. In addition, components such as the dust cup locking button are also integrated into the main body housing, making disassembly and maintenance inconvenient and affecting the locking strength and other performance characteristics.

[0003] Therefore, there is room for improvement in the ease of disassembling and assembling the main unit casing and the maintainability of the internal components of existing vacuum cleaners. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-module quick-release vacuum cleaner in order to solve the shortcomings of existing vacuum cleaners in terms of ease of disassembly and assembly of the main body shell and maintainability of internal components.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multi-module quick-release vacuum cleaner, comprising a vacuum cleaner main unit, a connecting tube, and a floor brush connected in sequence;

[0006] The vacuum cleaner main unit includes a lower housing, an upper housing, an air inlet structure, and a dust cup. The lower housing is provided with a hinge shaft, and the upper housing has a hinge lug at the handle. The hinge lug is rotatably connected to the hinge shaft. The edges of the lower housing and the upper housing are joined together to form a receiving cavity. A battery pack is provided on the handle. The first electrical interface of the battery pack is electrically connected to the second electrical interface of the circuit board on the lower housing. The air inlet structure passes through the receiving cavity and is sealed to the connecting seat of the lower housing. Its outer end is assembled and connected to the connector of the connecting pipe. The dust cup is assembled and connected to the lower housing through a first locking structure and a second locking structure. Its air inlet is sealed and connected to the connecting seat. The circuit board and the second locking structure are both located within the receiving cavity.

[0007] As a further description of the above technical solution:

[0008] The lower housing is provided with a plurality of first threaded posts, which are connected to the second threaded posts of the upper housing. A first fastener is inserted from one side of the lower housing or the upper housing and threaded onto the first threaded posts and the second threaded posts.

[0010] The inner end of the air inlet structure is provided with a tapered interface, which is inserted into the connector and sealed by a sealing ring.

[0011] As a further description of the above technical solution:

[0012] The lower housing is provided with a third threaded post, which abuts against the limiting sleeve of the air inlet structure. The second fastener passes through the limiting sleeve and is threaded onto the third threaded post.

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

[0014] The first locking structure includes a first hinge seat, a second hinge seat, a positioning bracket, and a first locking snap. The first hinge seat and the second hinge seat are rotatably connected. The second hinge seat is inserted into the positioning groove of the positioning bracket. The guide rib of the positioning groove is embedded in the notch on the edge of the second hinge seat. The first locking snap is elastically hinged to the positioning bracket by a spring. The first locking block on the snap engages and locks with the first locking block of the second hinge seat.

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

[0016] The second locking structure includes a locking member and a pressing member. The locking member is elastically slidably mounted on the first guide seat of the air inlet structure by a spring. The second locking block on the locking member passes through the first through hole of the lower housing and engages with the first slot of the dust cup. The pressing member is elastically slidably mounted on the second guide seat of the air inlet structure by a spring. The wedge-shaped block on the pressing member is inserted into the mating groove of the locking member and slides against the wedge-shaped guide surface of the mating groove. The outer end of the pressing member protrudes through the second through hole of the upper housing.

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

[0018] The lower housing is also provided with a third guide seat, and the ejector is slidably disposed on the third guide seat, with its outer end abutting against the dust cup. The third guide seat and the ejector are slidably engaged by a sliding groove and a rib to limit the sliding range. A compression spring is provided between the inner end of the ejector and the limiting seat of the upper housing.

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

[0020] The charging base is pressed against the inner side of the lower housing, and the charging contacts on it protrude through the third through hole of the lower housing.

[0022] The air inlet structure is embedded with an L-shaped seal. The seal is fitted onto the end of the connector. The first toothed ring inside the seal is tightly engaged with the second toothed ring at the end face of the connector. The connector is also provided with a second locking snap by means of a spring elastic sliding or hinge. The pressing block of the second locking snap passes through the through hole of the connector. The connector is inserted into the air inlet structure. The third locking block on the second locking snap engages with the second locking slot of the air inlet structure.

[0023] In summary, due to the adoption of the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0024] The vacuum cleaner of this invention utilizes a hinged lower and upper housing with screw positioning, allowing the main body housing to be disassembled for maintenance and disassembly of internal components such as the air intake structure, battery pack, circuit board, and charging base. The hinged design facilitates disassembly while providing guidance during assembly, ensuring proper structural alignment and improving assembly efficiency.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0042] Example 1:

[0043] Please see Figure 1-9 The present invention provides a technical solution: a multi-module quick-release vacuum cleaner, comprising a vacuum cleaner main unit 1, a connecting pipe 2, and a floor brush 3 connected in sequence.

[0044] The vacuum cleaner main unit 1 mainly consists of a lower housing 4, an upper housing 5, an air inlet structure 6, and a dust cup 7. A hinge shaft 8 is provided on the lower housing 4, and a hinge lug 10 is provided at the handle 9 of the upper housing 5. The hinge lug 10 is rotatably connected to the hinge shaft 8, allowing the upper housing 5 to open or close relative to the lower housing 4. When both are closed, the edges of the lower housing 4 and the upper housing 5 fit together, forming an internal cavity for accommodating components such as the circuit board 13.

[0045] The battery pack 11 is mounted on the handle 9, and its first electrical interface 12 is directly plugged into and electrically connected to the second electrical interface of the circuit board 13 fixed on the lower housing 4. The lower housing 4 is provided with a plurality of first screw posts 16, and the upper housing 5 is provided with a corresponding second screw post 17. The upper housing 5 and the lower housing 4 are fixed by screws (first fasteners) passing through the bottom of the lower housing 4 or the surface of the upper housing 5 and screwing into the first screw posts 16 and the second screw posts 17.

[0046] The dust cup 7 is mounted on the lower housing 4 via a first locking structure and a second locking structure. The first locking structure is located on one side (e.g., the bottom) of the dust cup 7 and includes a first hinge seat 21, a second hinge seat 22, a positioning bracket 23, and a first locking snap 27. The first hinge seat 21 is rotatably connected to the second hinge seat 22, and the second hinge seat 22 is inserted into the positioning groove 24 of the positioning bracket 23. The guide rib 25 in the positioning groove 24 is embedded in the notch 26 on the edge of the second hinge seat 22 for guidance. The first locking snap 27 is spring-loaded and elastically hinged to the positioning bracket 23, and its first locking block 28 engages with the corresponding locking block on the second hinge seat 22, thereby achieving side locking.

[0047] The second locking structure is located on the other side (e.g., the top) of the dust cup 7, and includes a locking member 29 and a pusher member 30. The locking member 29 is slidably mounted on the first guide seat 31 of the air inlet structure 6 by a spring, and its front end has a second locking block 32 that passes through the first through hole 33 of the lower housing 4 and engages with the first latch 34 on the dust cup 7. The pusher member 30 is slidably mounted on the second guide seat 35 of the air inlet structure 6 by a spring, and its inner end has a wedge block 36. The wedge block 36 is inserted into the mating groove of the locking member 29 and slides against the wedge-shaped guide surface 37 in the mating groove. The outer end of the pusher member 30 protrudes from the second through hole 38 of the upper housing 5 to form a button. When the user presses the pusher member 30, the wedge block 36 moves inward, pushing the locking member 29 to slide laterally against its spring force, causing the second locking block 32 to disengage from the first latch 34, thereby unlocking the device.

[0048] In addition, such as Figure 5-7 As shown, the locking member 29 engages with the oblong hole on the three sides of the bottom of the first guide seat 31 via a bottom locking block. When the bottom locking block is pressed in, the three sides of the bottom cover deform adaptively to achieve engagement, and the bottom locking block slides within the oblong hole to avoid interference. The hook on the side of the actuating member 30 engages with the slot on the side of the second guide seat 35 and can slide relative to it. When engaged, the hook elastically deforms inward to achieve structural clearance during engagement. This achieves a detachable design for the second locking structure, facilitating replacement and maintenance while ensuring stable performance.

[0049] This vacuum cleaner utilizes a hinged lower and upper housing with screw positioning, allowing the main body to be disassembled for maintenance and disassembly of internal components such as the air intake structure, battery pack, circuit board, and charging dock. The hinged design facilitates disassembly while providing guidance during assembly, ensuring proper placement and improving assembly efficiency. The battery pack and circuit board are connected or separated by the rotation of the lower and upper housings. During maintenance, the lower and upper housings are separated, allowing for the removal and replacement of both the battery pack and circuit board (mounted to the lower housing with screws), ensuring stable performance. The dust cup is positioned using a first and second locking structure, allowing for switching between dust cup positioning, dust outlet opening, and overall disassembly, enhancing ease of use. The second locking structure, integrated into the air intake structure and within the receiving cavity, is also replaceable to maintain locking performance.

[0050] Example 2:

[0051] Please see Figure 5 The figure shows a multi-module quick-release vacuum cleaner provided in Embodiment 2 of the present invention. Based on the above embodiments, this embodiment further improves upon the following technical solutions: The main body of the air inlet structure 6 is inserted into the accommodating cavity. The inner end of the air inlet structure 6 is provided with a tapered interface 18, which is inserted into the connecting seat 14 of the lower housing 4, and a sealing ring is provided between them to achieve structural docking guidance and airtight connection. The lower housing 4 is provided with a third threaded post 19, and the air inlet structure 6 is provided with a limiting sleeve 20. A screw (second fastener) passes through the limiting sleeve 20 and is screwed into the third threaded post 19 to fix the air inlet structure 6 to the lower housing 4, thereby achieving a quick-release design for the air inlet structure 6. The outer end of the air inlet structure 6 is used to dock with the connector 15 of the connecting pipe 2.

[0052] Example 3:

[0053] Please see Figure 5 , 6Figure 8 shows a multi-module quick-release vacuum cleaner provided in Embodiment 3 of the present invention. Based on the above embodiments, this embodiment further improves upon the following technical solutions: To facilitate the separation of the upper housing 5, dust cup 7, and lower housing 4 during disassembly, a third guide seat 39 is provided on the lower housing 4, in which an ejector 40 is slidably installed, with the outer end of the ejector 40 abutting against the dust cup 7. The sliding stroke is limited between the third guide seat 39 and the ejector 40 by a sliding groove and a rib. A compression spring 42 is installed between the inner end of the ejector 40 and the limiting seat 41 of the upper housing 5. When the second locking structure is unlocked, the compression spring 42 pushes the ejector 40, ejecting the dust cup 7 outward a certain distance, allowing the user to easily remove the dust cup 7. When the corresponding screw-connected positioning structure of the upper housing 5 and lower housing 4 separates and its positioning function is released, the compression spring 42 also extends, thereby achieving the separation of the upper housing 5 and lower housing 4 and improving disassembly efficiency.

[0054] Example 4:

[0055] Please see Figure 5 , 6 The figure shows a multi-module quick-release vacuum cleaner provided in Embodiment 4 of the present invention. Based on the above embodiments, this embodiment further improves upon the following technical solution: The charging base 43 is installed inside the lower housing 4, and its charging contacts protrude from the third through hole 44 of the lower housing 4. The connecting ears 45 on both sides of the charging base 43 are connected to the fourth threaded post of the lower housing 4 and locked in place by screws (third fasteners). The charging base 43 can only be disassembled from the inside of the lower housing 4 after the main housing structure is disassembled and opened. Compared with conventional external assembly of charging components, this allows for convenient disassembly while avoiding defects such as structural loosening and detachment inherent in external assembly.

[0056] Example 5:

[0057] Please see Figure 2 , 9The figure shows a multi-module quick-release vacuum cleaner provided in Embodiment 5 of the present invention. Based on the above embodiments, this embodiment further improves upon the following technical solutions: To ensure quick disassembly and good sealing between the connecting pipe 2 and the vacuum cleaner main unit 1, an L-shaped sealing element 46 is embedded in the air inlet structure 6. This sealing element 46 is fitted onto the end of the connector 15. The inner ring of the sealing element 46 has a first toothed ring 47, and the end face of the connector 15 has a second toothed ring 48. When the connector 15 is inserted into place, the first toothed ring 47 and the second toothed ring 48 tightly fit together to form a labyrinth seal. A second locking snap 49 is also elastically provided on the connector 15 via a spring. A pressing block 50 on the snap 49 protrudes from the through hole of the connector 15, and a third locking block 51 engages with a second locking slot 52 on the inner wall of the air inlet structure 6. Pressing the pressing block 50 disengages the third locking block 51 from the second locking slot 52, thereby allowing the connector 15 to be pulled out. In addition to the above-described connection between the connecting tube 2 and the vacuum cleaner main unit 1, the connection between the connecting tube 2 and the floor brush 3 also adopts the above-described structural layout. Specifically, the floor brush 3 is equipped with a connector 15 and a second locking snap 49, and the connecting tube 2 is equipped with a sealing element 46 and a second bayonet 52. Figure 1 , 2 As shown, this improves the sealing performance of the internal air duct connection nodes of the vacuum cleaner, as well as the convenience of component assembly and disassembly and the stability of positioning.

[0058] The working principle of a multi-module quick-release vacuum cleaner according to the above embodiment includes:

[0059] When emptying the dust cup, the pusher protrudes from the second through hole in the upper housing and presses inward. The wedge-shaped block at the inner end of the pusher further inserts into the mating groove of the locking member and slides along the wedge-shaped guide surface, driving the locking member to slide laterally against the spring force. This causes the second locking block on the locking member to disengage from the first locking slot of the dust cup. The ejector located in the third guide seat is pushed outward under the action of the compression spring, ejecting the dust cup a certain distance, thus opening the dust discharge port at the front of the dust cup to empty the dust.

[0060] When the dust cup needs to be removed for cleaning, maintenance, or replacement of the dust cup and its internal filter components, press the first locking button to disengage its latch from the corresponding first latch on the second hinge seat. Then pull out the positioning bracket from the second hinge seat. The first locking structure is located on the other side of the dust cup; after unlocking, the dust cup is completely detached from the lower housing.

[0061] When it is necessary to disassemble the main unit housing structure, which consists of a lower housing and an upper housing, for maintenance of the components within the accommodating cavity, remove the corresponding screws on the housing to release the positioning of the lower and upper housings. The spring force will then push them apart, separating them and opening the accommodating cavity for the corresponding operations. For disassembly of the air inlet structure, remove the corresponding screws and pull the air inlet structure out of the connector to complete the disassembly. This split design also facilitates cleaning of the dust cup's air inlet side piping, ensuring smooth flow.

[0062] The connection between the connecting tube and the vacuum cleaner main unit and floor brush has a similar structural design. Taking the disassembly process of the connecting tube and the vacuum cleaner main unit as an example, the pressing block is located at the through hole on the side of the connector. Press it inward. The pressing action causes the second locking snap to move against the spring force, and the third latch on it disengages from the second latch on the inner wall of the air intake structure. While maintaining the pressing state, pull the connecting tube outward to completely remove the connector from the air intake structure.

[0063] In summary, due to the adoption of the above technical solution, the multi-module quick-release vacuum cleaner of this embodiment has the following advantages compared with the prior art:

[0064] The vacuum cleaner of this invention utilizes a hinged lower and upper housing with screw positioning, allowing the main body housing to be disassembled for maintenance and disassembly of internal components such as the air intake structure, battery pack, circuit board, and charging base. The hinged design facilitates disassembly while providing guidance during assembly, ensuring proper structural alignment and improving assembly efficiency. The battery pack and circuit board are connected or separated by the rotation of the lower and upper housings. During maintenance, the lower and upper housings are separated, allowing for disassembly and replacement of both the battery pack and circuit board, ensuring stable performance. The dust cup is positioned using a first and second locking structure, enabling switching between dust cup positioning, dust outlet opening, and overall disassembly, improving ease of use. The second locking structure, integrated into the air intake structure and within the accommodating cavity, is also replaceable to maintain locking performance. The connector and seal are joined by a toothed ring, ensuring a tight fit at the internal air duct connection and guaranteeing airtightness.

[0065] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
