Description

Technical Field

[0001] This application relates to the field of vacuum cleaners, and more particularly to a vacuum cleaner reversing structure. Background Technology

[0002] Significant progress has been made in the field of vacuum cleaner motor technology in recent years in improving efficiency and reducing noise. As users' demands for vacuum cleaner performance increase, achieving multi-functionality without increasing energy consumption has become a major direction for technological development. As one of the key technologies in this field, the commutation technology of vacuum cleaner motors directly affects the overall performance and user experience of vacuum cleaners.

[0003] Currently, most mainstream vacuum cleaner motors on the market use a single airflow direction design, making it difficult to achieve a blowing function and limiting the application range of vacuum cleaners. For example, during the use of household robotic vacuum cleaners, it is often necessary to clean the screen. The conventional method is to disassemble the device, disturb the screen, and sweep away surface dust, which is relatively cumbersome. To address the need for a blowing function in vacuum cleaners, existing technologies mostly use a bidirectional motor design, using a complex control system to switch the airflow direction. This solution increases the product size and cost, and is prone to component wear during frequent switching; although it achieves airflow direction switching, the control system is complex and has high manufacturing costs. Utility Model Content

[0004] In order to reduce the manufacturing cost of airflow reversal, this application provides a vacuum cleaner reversal structure.

[0005] The vacuum cleaner reversing structure provided in this application adopts the following technical solution:

[0006] A vacuum cleaner reversing structure includes a reversing body with an inner cavity. A partition plate is provided within the reversing body, dividing the inner cavity into two areas. The two areas of the inner cavity are respectively connected to the air outlet and air inlet of a motor. A baffle is provided at the opening of the inner cavity of the reversing body, rotatably connected to the reversing body. Symmetrically arranged ventilation openings are provided on the baffle, each communicating with one of the areas of the reversing body. Two channels are connected to the end of the reversing body near the baffle, and the baffle rotates to switch the communication between the channel and the air outlet or air inlet.

[0007] By adopting the above technical solution, a partition plate is installed within the reversing body to divide the inner cavity into two areas, which are respectively connected to the motor's air outlet and air inlet. This allows the airflow to flexibly switch between two directions, meeting the dual functional requirements of vacuuming and blowing, thus enhancing the versatility of the vacuum cleaner. The baffle is rotatably connected to the reversing body, and symmetrical vents are arranged on the baffle. This design simplifies the structure for switching airflow direction, avoids the use of complex control systems, and reduces manufacturing costs and product size. Two channels are connected to the end of the reversing body near the baffle; rotating the baffle allows for switching between the channels and either the air outlet or air inlet. The operation is simple and reliable, improving the user experience. This achieves convenient switching of the vacuum cleaner's airflow direction.

[0008] Preferably, the commutator body includes a commutator ring cover, a rotating connecting frame, a commutator base plate, a closing bend plate, and a closing ring plate. Both ends of the rotating connecting frame are connected to the inner wall of the commutator ring cover. The partition plate is abutted against the rotating connecting frame. The baffle is rotatably connected to the rotating connecting frame, and the end wall of the baffle near the partition plate can abut against the top wall of the partition plate and the top wall of the baffle rotating frame. The closing bend plate is mounted on the commutator ring cover, and the outer edge sidewall of the commutator base plate is connected to the side of the closing bend plate away from the commutator ring cover. The reversing base plate, at the end away from the closed bend plate, forms an air outlet channel with the reversing ring cover. The reversing base plate is also connected to the rotating connecting frame and the partition plate. An air inlet channel is provided on the reversing base plate. The reversing ring cover, reversing base plate, closed bend plate, and partition plate are combined to form an inner cavity with two regions. The air inlet channel and the air outlet channel are respectively connected to one region. The closed ring plate is installed at the end of the reversing base plate away from the partition plate. The air inlet channel is located in the inner ring of the closed ring plate, and the air outlet channel is located in the outer ring of the closed ring plate.

[0009] By adopting the above technical solution, the reversing body consists of a reversing ring cover, a rotating connecting frame, a reversing base plate, a closed bend plate, and a closed ring plate, forming two independent inner cavities, with airflow separation achieved through a partition plate. The baffle is rotatably connected to the rotating connecting frame, ensuring a tight fit with the partition plate and the baffle rotating frame, guaranteeing airtightness during airflow switching. The cooperation between the closed bend plate and the reversing base plate allows the air inlet and outlet channels to connect to the two areas respectively, achieving effective switching of airflow direction. The design of the closed ring plate further optimizes the structural layout, placing the air inlet channel in the inner ring and the air outlet channel in the outer ring, improving space utilization. The overall structural design is compact, reducing manufacturing costs while simplifying the control system and improving the vacuum cleaner's versatility and user experience.

[0010] Preferably, the reversing ring cover is further provided with two arc-shaped sealing plates. The two arc-shaped sealing plates are respectively connected to the inner walls of the reversing ring cover located in two regions. The two ends of one arc-shaped sealing plate are respectively connected to the two ends of the partition plate, and the two ends of the other arc-shaped sealing plate are respectively connected to the two ends of the rotating connecting frame.

[0011] By adopting the above technical solution, two arc-shaped sealing plates are connected to the inner wall of the reversing ring cover, and cooperate with the partition plate and rotating connecting frame to form a more reliable separation structure, ensuring that the airflow in the two areas does not interfere with each other, thereby achieving precise airflow direction switching and reducing energy loss. The arc-shaped sealing plates can effectively enhance the sealing between the two areas of the reversing body's internal cavity, preventing airflow leakage or mixing during the reversing process, thereby improving the efficiency of airflow reversal.

[0012] Preferably, the end wall of the baffle near the partition plate can be attached to the top wall of the arc-shaped sealing plate, and the peripheral wall of the baffle can be attached to the inner wall of the reversing ring cover; the reversing ring cover has a turning arc-shaped notch, and a lever is provided on the peripheral wall of the baffle. The lever protrudes and is inserted into the arc-shaped notch, and the lever can move circumferentially within the arc-shaped notch.

[0013] By adopting the above technical solution, the design of the paddle being inserted into the arc-shaped notch and moving circumferentially simplifies the rotation control of the baffle, reduces operational complexity, and improves the stability and reliability of the reversing process. The tight fit between the baffle and the arc-shaped sealing plate and the inner wall of the reversing ring effectively reduces airflow leakage and improves the sealing performance of the reversing structure, thereby ensuring the accuracy of airflow direction switching.

[0014] Preferably, the paddle is provided through the arc-shaped notch to protrude; the protruding part of the paddle is provided with a guide surface.

[0015] By adopting the above technical solution, the paddle is designed to extend through the arc-shaped notch and protrude, allowing for direct external operation. This simplifies the rotation control of the baffle and reduces structural complexity. Simultaneously, the protruding part of the paddle features a guide surface, effectively reducing resistance as it moves within the arc-shaped notch, improving operational smoothness, and enabling more convenient airflow direction switching. This further reduces manufacturing costs and maintenance difficulty.

[0016] Preferably, the end walls of the arc-shaped sealing plate and the partition plate that contact the baffle are provided with friction-reducing grooves.

[0017] By adopting the above technical solution, the friction-reducing groove effectively reduces the friction between the baffle and the arc-shaped sealing plate and partition plate during rotation, reducing component wear caused by friction and thus extending the service life of the vacuum cleaner's reversing structure. At the same time, the lower friction makes the baffle rotate more smoothly, reducing operating resistance and improving the reliability and efficiency of airflow reversal.

[0018] Preferably, the outer ring of the closed ring plate is provided with an abutting ring block, and the end of the reversing ring cover near the closed ring plate is provided with an abutting ring groove. The bottom of the abutting ring groove is flush with the end wall of the abutting ring block away from the reversing base plate, and the bottom of the abutting ring groove and the abutting ring block can abut against the outer shell of the motor.

[0019] By adopting the above technical solution, the abutting ring block set on the outer ring of the closed ring plate and the abutting ring groove opened at the end of the reversing ring cover cooperate with each other, so that the bottom of the abutting ring groove and the abutting ring block can abut against the motor housing together, thereby realizing the stable installation of the vacuum cleaner reversing structure on the motor and improving the stability and reliability of the overall structure.

[0020] Preferably, a reinforcing ring block is provided at the connection between the reversing base plate and the closing ring plate, and the end wall of the reinforcing ring block away from the reversing base plate forms a closing wall.

[0021] By adopting the above technical solution, a reinforcing ring block is installed at the connection between the reversing base plate and the closed ring plate, which enhances the overall strength of the structure and prevents loosening or damage at the connection due to vibration or pressure changes during frequent airflow switching, thereby improving the service life of the vacuum cleaner's reversing structure. The end wall of the reinforcing ring block away from the reversing base plate forms a closed wall, further improving the sealing performance of the structure, preventing external dust or impurities from entering the inner cavity, and ensuring the stability and reliability of airflow reversal.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By incorporating a partition within the reversing body to divide the inner cavity into two areas, each connected to the motor's air outlet and inlet respectively, airflow can be flexibly switched between the two directions, satisfying both vacuuming and blowing functions and enhancing the vacuum cleaner's versatility. The baffle is rotatably connected to the reversing body, and symmetrically arranged ventilation openings on the baffle simplify the airflow direction switching structure, avoids the use of complex control systems, and reduces manufacturing costs and product size. Two channels are connected to the end of the reversing body near the baffle; rotating the baffle allows for switching between these channels and either the air outlet or inlet, providing simple and reliable operation and improving the user experience. This achieves convenient switching of the vacuum cleaner's airflow direction.

[0024] 2. The reversing body consists of a reversing ring cover, a rotating connecting frame, a reversing base plate, a closed bend plate, and a closed ring plate, forming two independent inner cavities, with airflow separation achieved through a partition plate. The baffle is rotatably connected to the rotating connecting frame, ensuring a tight fit with the partition plate and the baffle rotating frame, guaranteeing airtightness during airflow switching. The cooperation between the closed bend plate and the reversing base plate allows the air inlet and outlet channels to connect to the two areas respectively, achieving effective switching of airflow direction. The design of the closed ring plate further optimizes the structural layout, placing the air inlet channel in the inner ring and the air outlet channel in the outer ring, improving space utilization. The overall structural design is compact, reducing manufacturing costs while simplifying the control system and improving the vacuum cleaner's versatility and user experience.

[0025] 3. The design of the paddle inserting into the arc-shaped notch and moving circumferentially simplifies the rotation control of the baffle, reduces operational complexity, and improves the stability and reliability of the reversing process. The tight fit between the baffle and the arc-shaped sealing plate and the inner wall of the reversing ring effectively reduces airflow leakage and improves the sealing performance of the reversing structure, thereby ensuring the accuracy of airflow direction switching.

[0030] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0031] This application discloses a reversing structure for a vacuum cleaner. (Refer to...) Figure 1A vacuum cleaner reversing structure includes a reversing body 1, within which an inner cavity 2 is formed. A partition 3 is disposed within the reversing body 1, dividing the inner cavity 2 into two regions 21. The two regions 21 of the inner cavity 2 are respectively connected to the air outlet and air inlet of the motor. A baffle 4 is disposed at the opening of the inner cavity 2 of the reversing body 1, rotatably connected to the reversing body 1. Symmetrically arranged ventilation openings 41 are provided on the baffle 4, each ventilation opening 41 communicating with one of the regions 21 of the reversing body 1. The end of the reversing body 1 near the baffle 4 is connected to two channels. Rotation of the baffle 4 switches the channel's connection to either the air outlet or the air inlet. In use, each ventilation opening 41 of the baffle 4 always corresponds to one channel; rotation of the baffle 4 only changes the connection between the ventilation opening 41 and the air outlet or air inlet of the motor.

[0032] By setting a partition plate 3 inside the reversing body 1, the inner cavity 2 is divided into two areas 21, which are respectively connected to the air outlet and air inlet of the motor. This allows the airflow to switch flexibly in two directions, meeting the dual functional requirements of vacuuming and blowing, and improving the versatility of the vacuum cleaner. A baffle 4 is rotatably connected to the reversing body 1, and vents 41 are symmetrically arranged on the baffle 4. This design simplifies the structure for switching airflow direction, avoids the use of complex control systems, and reduces manufacturing costs and product size. Two channels are connected to the end of the reversing body 1 near the baffle 4. Rotating the baffle 4 allows the channels to switch between the air outlet and the air inlet or outlet, making operation simple and reliable and improving the user experience.

[0033] Reference Figure 2 and Figure 3 The commutator body 1 includes a commutator ring cover 11, with a partition plate 3 installed on the inner wall of the commutator ring cover 11, and the partition plate 3 passing through the virtual center of the commutator ring cover 11. A rotating connecting frame 12 is also connected inside the commutator ring cover 11, with the partition plate 3 and the rotating connecting frame 12 in contact, meaning that the rotating connecting frame 12 and the partition plate 3 together divide the commutator ring cover 11 into two parts. A baffle 4 is rotatably connected to the rotating connecting frame 12, and the end wall of the baffle 4 near the partition plate 3 can be in contact with the top wall of the partition plate 3 and the top wall of the rotating frame of the baffle 4.

[0034] A closed ring plate 15 is connected to the inner wall of the reversing ring cover 11 on the side away from the baffle 4. A reversing base plate 13 is integrally formed on the inner wall of the closed ring plate 15 away from the reversing ring cover 11. The reversing base plate 13 is also connected to the rotating connecting frame 12 and the partition plate 3. An air outlet channel 5 is formed between the end of the reversing base plate 13 away from the closed bending plate 14 and the reversing ring cover 11. An air inlet channel 6 is opened at the center of the reversing base plate 13. The reversing ring cover 11, the reversing base plate 13, the closed bending plate 14 and the partition plate 3 are combined to form an inner cavity 2 with two regions 21. The air inlet channel 6 and the air outlet channel 5 are respectively connected to one region 21. At the same time, the air inlet channel 6 is connected to the air inlet of the motor, and the air outlet channel 5 is connected to the air outlet of the motor.

[0035] Two arc-shaped sealing plates 16 are also provided inside the reversing ring cover 11. The two arc-shaped sealing plates 16 are respectively connected to the inner wall of the reversing ring cover 11 located in the two regions 21. The two ends of one arc-shaped sealing plate 16 are respectively connected to the two ends of the partition plate 3, and the two ends of the other arc-shaped sealing plate 16 are respectively connected to the two ends of the rotating connecting frame 12.

[0036] The end wall of the baffle 4 near the partition plate 3 can be in contact with the top wall of the arc-shaped sealing plate 16, and the peripheral wall of the baffle 4 can be in contact with the inner wall of the reversing ring cover 11. The end walls of the arc-shaped sealing plate 16 and the partition plate 3 that are in contact with the baffle 4 are provided with friction-reducing grooves 17.

[0037] The reversing ring cover 11 has a steering arc-shaped notch 111, and a paddle 42 is integrally formed on the peripheral wall of the baffle 4. The paddle 42 passes through the steering arc-shaped notch 111 and protrudes outward. The protruding part of the paddle 42 is provided with a guide surface 43. The paddle 42 can move circumferentially along the reversing ring cover 11 within the steering arc-shaped notch 111, thereby controlling the ventilation port 41 on the baffle 4 to exchange the communication area 21.

[0038] Reference Figure 2 and Figure 3 A closed ring plate 15 is integrally formed at the end of the commutator base plate 13 away from the partition plate 3. The air inlet channel 6 is located in the inner ring of the closed ring plate 15, and the air outlet channel 5 is located in the outer ring of the closed ring plate 15. An abutment ring block 18 is integrally formed on the outer ring of the closed ring plate 15. An abutment ring groove 112 is formed at the end of the commutator ring cover 11 near the closed ring plate 15. The bottom of the abutment ring groove 112 is flush with the end wall of the abutment ring block 18 away from the commutator base plate 13, and the bottom of the abutment ring groove 112 and the abutment ring block 18 can abut against the motor housing. A reinforcing ring block 19 is integrally formed at the connection between the commutator base plate 13 and the closed ring plate 15. The end wall of the reinforcing ring block 19 away from the commutator base plate 13 forms a closed wall 191.

[0039] The implementation principle of the vacuum cleaner reversing structure in this embodiment is as follows: When the vacuum cleaner needs to change the airflow direction to backflush the filter, the lever 42 is moved within the turning arc-shaped notch 111. At this time, the baffle 4 rotates, and the two vents 41 on the baffle 4 exchange their connected areas 21. The vent 41 corresponding to the filter on the baffle 4 then changes from the motor's air inlet to the motor's air outlet, meaning the two vents 41 on the baffle 4 exchange their connected inner cavity 2 areas 21. This design simplifies the airflow direction switching structure, avoids the use of complex control systems, and reduces manufacturing costs and product size.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
