Description

Technical Field

[0001] This invention relates to the field of vacuum cleaner motor technology, specifically to a vacuum cleaner motor. Background Technology

[0002] The motor is the heart of a vacuum cleaner. Vacuum cleaner motors mainly include dry vacuum cleaner motors and wet / dry vacuum cleaner motors, and a vacuum cleaner motor consists of a motor part and a fan part.

[0003] Currently, vacuum cleaner motors differ from ordinary mechanical motors, having more internal components and more complex parts. While existing vacuum cleaner motors can meet daily vacuuming needs, the complexity of their internal structure, while improving functionality, also increases the frequency of malfunctions due to the more delicate parts. Therefore, regular disassembly of the outer casing is necessary for internal component maintenance. However, most existing vacuum cleaner motor casings are one-piece sleeve structures, requiring complete disassembly for installation and removal, and tightening all bolts after maintenance. In most cases, routine maintenance only requires partial disassembly of the outer casing, which not only increases the labor intensity of repetitive work for operators but also increases the probability of bolt loss, thus causing great inconvenience to daily maintenance operations.

[0004] Furthermore, due to the special working environment of the vacuum cleaner motor, the probability of dust adhering to it is increased. Therefore, it needs to be cleaned regularly to ensure the normal operation of internal components and to ensure internal air circulation, avoiding excessive blockage that would prevent heat dissipation. Although this requires disassembling the entire vacuum cleaner motor housing, removing multiple bolts at the same time will also cause inconvenience to the operator. Moreover, the one-piece sleeve-type housing structure is not convenient for the operator to clean its interior, thus increasing the difficulty of cleaning.

[0005] Meanwhile, due to the more complex internal structure of vacuum cleaner motors, the heat generated during operation also increases. While the heat dissipation function of existing vacuum cleaner motors is mostly no different from that of ordinary mechanical motors, they generate more heat than ordinary motors, which greatly reduces the heat dissipation efficiency. Since vacuum cleaner motors contain precision structures such as sensors and solenoid valves, low heat dissipation efficiency can cause significant damage to these components. Therefore, it is necessary to develop a new type of vacuum cleaner motor structure that is easy to disassemble, inspect, and clean, and has better heat dissipation efficiency. Summary of the Invention

[0006] I. Technical problems to be solved

[0007] This invention addresses the aforementioned deficiencies in existing technologies by proposing a vacuum cleaner motor that solves the problems of inconvenient disassembly, maintenance, and cleaning, as well as low heat dissipation efficiency in existing vacuum cleaner motors.

[0008] II. Technical Solution

[0009] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a vacuum cleaner motor, including a base, a motor body fixedly installed on the top of the base, a plurality of housing components located outside the motor body movably connected to the top of the base, a recycling bin fixedly installed on the top of the motor body, a drain pipe fixedly connected to the top of the recycling bin, a positioning plate fixedly sleeved on the outer surface of the drain pipe, a positioning sleeve threaded onto the outer surface of the positioning plate, the bottom of the positioning sleeve movably connected to the top of the housing components, a snap-fit ​​groove located at the bottom of the housing components being opened on the top of the base, a plurality of snap-fit ​​plates being movably snapped into the inside of the snap-fit ​​groove, and a plurality of locking mechanisms being provided on the side of the base. Due to the housing components, it is convenient for operators to disassemble parts of the motor, thereby facilitating daily maintenance.

[0010] Preferably, the number of housing components, locking mechanisms, snap-fit ​​slots, and snap-fit ​​plates are all the same, and the housing components include a shell, a heat sink, an assembly slot, and a connecting strip. The bottom of the shell is fixedly connected to the top of the snap-fit ​​plate, the top of the shell is movably connected to the bottom of the positioning sleeve, the shell and the heat sink are fixedly connected, the inner wall of the assembly slot is movably snapped into the outer surface of the connecting strip, and adjacent shells are movably connected through the assembly slot and the connecting strip. Through the provided assembly slot and connecting strip, the stability of the connection between adjacent shells can be ensured by their cooperation, thereby improving the tightness of the assembly of the housing components.

[0011] Preferably, the locking mechanism includes a threaded sleeve, a transmission gear shaft, a threaded rod, and a knob. The outer surface of the threaded sleeve is threadedly engaged with the inner wall of the base, and the inner wall of the threaded sleeve is threadedly engaged with the outer surface of the threaded rod. The right end of the threaded sleeve passes through the base and is fixedly connected to the transmission gear shaft. The right end of the threaded rod passes through the threaded sleeve and is fixedly connected to the knob. Due to the threaded rod, it can move under the drive of the knob or the threaded sleeve and the transmission gear shaft, thereby locking the snap-fit ​​plate with the cooperation of the base and the snap-fit ​​groove.

[0012] Preferably, the left end of the threaded rod passes through the threaded sleeve and extends into the interior of the base, where it contacts the snap-fit ​​plate; the transmission gear shaft and the base are in contact connection; and the knob and the transmission gear shaft are in contact connection.

[0013] Preferably, the outer surface of the base is movably engaged with a toothed plate located below the locking mechanism. The top of the toothed plate meshes with the outer surface of the transmission gear shaft, and the bottom of the toothed plate is fixedly connected with a rotating sleeve. The inner wall of the rotating sleeve is movably engaged with the outer surface of the base. With the toothed plate, the operator can easily rotate multiple transmission gear shafts simultaneously with the help of the rotating sleeve, thereby facilitating the operator to quickly disassemble the entire housing assembly.

[0014] Preferably, a protective cover connecting sleeve is fixedly connected to the bottom of the base, and a protective cover is threaded onto the outer surface of the protective cover connecting sleeve, with the top of the protective cover in contact with the bottom of the base.

[0015] Preferably, a filter plate is movably attached to the bottom of the protective cover. The filter plate is made of elastic plastic. The filter plate allows the operator to easily replace it, enabling the vacuum cleaner to clean debris of different sizes, thereby improving its applicability.

[0016] Preferably, the base has an inlet trough located below the housing assembly and the motor body. The inner wall of the inlet trough has a spiral structure, and the inlet trough is connected to the recycling bin through a sealed cavity. Due to the inlet trough, the spiral direction of the inner wall of the inlet trough is the same as the direction of the fan blade movement. Under the guidance of its inner wall, it can facilitate the flow of air and dust, ensuring that the air inside the base and the protective cover can move along the inner wall of the inlet trough under the drive of the fan blade, reducing the resistance after the air and dust pushed by the fan blade enter the base.

[0017] Preferably, both the base and the motor body have spirally opened drainage holes inside. The bottom of the drainage hole penetrates the base and communicates with the inside of the protective cover. The top of the sludge inlet penetrates the motor body and is fixedly connected to a water guide pipe. The water guide pipe is fixedly connected to the outer surface of the motor body. The water guide pipe allows the solenoid valve and connecting pipe to inject water into multiple drainage holes simultaneously, thereby making the water flow distribution more uniform and ensuring that the water flow quickly removes more heat from the surface of the motor body.

[0018] Preferably, a solenoid valve is fixedly connected to the right side of the water guide pipe, a connecting pipe is fixedly connected to the right side of the solenoid valve, a water delivery hose is fixedly sleeved inside the connecting pipe, and the other end of the water delivery hose is distributed along the outer surface of the recycling box and passes through the positioning plate.

[0019] III. Beneficial Effects

[0020] Compared with the prior art, the present invention uses a threaded sleeve, a transmission gear shaft, a threaded rod, and a toothed plate to release the locking of the positioning sleeve on the top of the housing assembly. After the rotating sleeve is released, the toothed plate can drive multiple transmission gear shafts to rotate, thereby simultaneously releasing the locking of multiple threaded rods on the snap-fit ​​plate. This allows for the simultaneous release of the locking of multiple housing assemblies, facilitating overall disassembly. Furthermore, rotating any one of the knobs individually can release the locking of the corresponding snap-fit ​​plate by the corresponding threaded rod under the restriction of the toothed plate on the transmission gear shaft and the threaded sleeve. This allows operators to disassemble parts of the housing assembly, facilitating daily inspection, maintenance, and cleaning operations.

[0021] The housing assembly, positioning plate, positioning sleeve, and snap-fit ​​plate, along with the snap-fit ​​groove and snap-fit ​​plate, allow operators to easily fix the bottom of the housing assembly. The assembly groove and connecting strip facilitate the assembly or disassembly of multiple housings. The positioning plate and positioning sleeve lock the top of multiple housings, making it easier to disassemble and assemble the whole assembly and to facilitate routine cleaning of the equipment's interior.

[0022] The system includes a sludge inlet, a drain hole, a water pipe, and a solenoid valve. The sludge inlet ensures that the air and dust driven by the fan blades move along the inner wall of the sludge inlet, reducing the resistance of the base and sludge inlet to air and dust, thereby improving the efficiency of the fan blades' dust collection operation. The water pipe and solenoid valve allow water from the water supply hose and connecting pipe to be discharged through the drain hole. This not only facilitates the selection of dry dust collection but also allows the water flow to remove heat from the surface of the motor body, thereby improving heat dissipation and cooling efficiency.

Detailed Implementation

[0031] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention. Example 1

[0032] like Figures 1 to 7 As shown, the vacuum cleaner motor in this embodiment of the invention includes a base 1, a motor body 3 fixedly mounted on the top of the base 1, several housing components 2 located outside the motor body 3 movably connected to the top of the base 1, a recycling bin 4 fixedly mounted on the top of the motor body 3, a drain pipe 5 fixedly connected to the top of the recycling bin 4, a positioning plate 6 fixedly sleeved on the outer surface of the drain pipe 5, a positioning sleeve 7 threadedly sleeved on the outer surface of the positioning plate 6, the bottom of the positioning sleeve 7 movably connected to the top of the housing component 2, a snap-fit ​​groove 11 located at the bottom of the housing component 2 is opened on the top of the base 1, several snap-fit ​​plates 12 are movably snapped into the inside of the snap-fit ​​groove 11, and several locking mechanisms 8 are provided on the side of the base 1. Due to the setting of the housing component 2, it is convenient for operators to disassemble parts, thereby facilitating daily maintenance work.

[0033] Furthermore, the number of housing components 2, locking mechanisms 8, snap-fit ​​grooves 11, and snap-fit ​​plates 12 are all the same, and each housing component 2 includes a housing 201, a heat sink 202, an assembly groove 203, and a connecting strip 204. The bottom of the housing 201 is fixedly connected to the top of the snap-fit ​​plate 12, the top of the housing 201 is movably connected to the bottom of the positioning sleeve 7, the housing 201 and the heat sink 202 are fixedly connected, the inner wall of the assembly groove 203 is movably snapped into the outer surface of the connecting strip 204, and adjacent housings 201 are movably connected through the assembly groove 203 and the connecting strip 204. Through the provided assembly groove 203 and connecting strip 204, the stability of the connection between adjacent housings 201 can be ensured by their cooperation, thereby improving the tightness of the assembly of the housing components 2.

[0034] like Figure 3As shown, the locking mechanism 8 includes a threaded sleeve 801, a transmission gear shaft 802, a threaded rod 803, and a knob 804. The outer surface of the threaded sleeve 801 is threadedly connected to the inner wall of the base 1, and the inner wall of the threaded sleeve 801 is threadedly connected to the outer surface of the threaded rod 803. The right end of the threaded sleeve 801 passes through the base 1 and is fixedly connected to the transmission gear shaft 802. The right end of the threaded rod 803 passes through the threaded sleeve 801 and is fixedly connected to the knob 804. Due to the setting of the threaded rod 803, it can move under the drive of the knob 804 or the threaded sleeve 801 and the transmission gear shaft 802, so that the locking plate 12 can be locked in cooperation with the base 1 and the locking groove 11.

[0035] The left end of the threaded rod 803 passes through the threaded sleeve rod 801 and extends into the interior of the base 1 and contacts the snap-fit ​​plate 12. The transmission gear shaft 802 is in contact with the base 1, and the knob 804 is in contact with the transmission gear shaft 802.

[0036] A toothed plate 9 located below the locking mechanism 8 is movably engaged on the outer surface of the base 1. The top of the toothed plate 9 meshes with the outer surface of the transmission gear shaft 802. A rotating sleeve 10 is fixedly connected to the bottom of the toothed plate 9. The inner wall of the rotating sleeve 10 is movably engaged with the outer surface of the base 1. With the toothed plate 9, the operator can easily rotate multiple transmission gear shafts 802 simultaneously with the help of the rotating sleeve 10, which facilitates the operator to quickly disassemble the entire housing assembly 2. Furthermore, a protective cover connecting sleeve 13 is fixedly connected to the bottom of the base 1. A protective cover 14 is threaded onto the outer surface of the protective cover connecting sleeve 13. The top of the protective cover 14 contacts the bottom of the base 1. A filter plate 18 is movably engaged at the bottom of the protective cover 14. The filter plate 18 is made of elastic plastic. With the filter plate 18, the operator can easily replace the filter plate 18, enabling the vacuum cleaner to clean debris of different volumes, thereby improving its applicability.

[0037] Inside the base 1, there is a sludge inlet 19 located below the housing assembly 2 and the motor body 3. The inner wall of the sludge inlet 19 has a spiral structure, and the sludge inlet 19 is connected to the recycling box 4 through a sealed cavity. Due to the setting of the sludge inlet 19, the spiral direction of the inner wall of the sludge inlet 19 is the same as the direction of movement of the fan blade 17. Under the guidance of its inner wall, it can facilitate the flow of air and dust, ensuring that the air inside the base 1 and the protective cover 14 can move along the inner wall of the sludge inlet 19 under the drive of the fan blade 17, reducing the resistance after the air and dust pushed by the fan blade 17 enter the interior of the base 1.

[0038] During maintenance of the motor in this embodiment, the rotating positioning sleeve 7 can release the lock on the top of the housing assembly 2. Then, according to the needs of local maintenance, the lock on the bottom snap plate 12 of the corresponding housing assembly 2 can be released. That is, while fixing the toothed plate 9 and the rotating sleeve 10, the corresponding knob 804 can be rotated. Under the restriction of the toothed plate 9 on the transmission gear shaft 802, the threaded rod 803 can be screwed out through the cooperation of the threaded sleeve rod 801 and the threaded rod 803, thereby releasing the lock on the corresponding snap plate 12. Then, with the cooperation of the assembly groove 203 and the connecting strip 204, the snap plate 12 can be pulled out from the inside of the snap groove 11 through the outer shell 201, so that the corresponding housing assembly 2 can be completely removed, and then the part can be inspected and maintained.

[0039] When it is necessary to clean the inside, first rotate the positioning sleeve 7. With the cooperation of the positioning plate 6, the positioning sleeve 7 completely releases the locking of multiple housing components 2. Then, rotate the rotating sleeve 10. Under the restriction of the base 1, the toothed plate 9 drives the transmission gear shaft 802 to rotate slowly. The rotation of the transmission gear shaft 802, with the cooperation of the base 1 and the threaded sleeve 801, causes the threaded sleeve 801 and the transmission gear shaft 802 to move to the right as a whole. The movement of the threaded sleeve 801 can drive the threaded rod 803 and the knob 804 to move to the right as a whole, thereby simultaneously releasing the locking of multiple locking mechanisms 8 on multiple snap-fit ​​plates 12. Then, all multiple housing components 2 can be removed to complete the disassembly. Finally, they can be cleaned. Example 2

[0040] Compared to Embodiment 1, in this embodiment, both the base 1 and the motor body 3 have spirally opened drainage holes 20 inside. The bottom of the drainage hole 20 penetrates the base 1 and is interconnected with the interior of the protective cover 14. The top of the sludge inlet trough 19 penetrates the motor body 3 and is fixedly connected to a water guide pipe 21. The water guide pipe 21 is fixedly connected to the outer surface of the motor body 3. The water guide pipe 21 allows the solenoid valve 22 and the connecting pipe 23 to simultaneously inject water into multiple drainage holes 20, thereby making the water flow distribution more uniform and ensuring that the water flow quickly removes more heat from the surface of the motor body 3. A solenoid valve 22 is fixedly connected to the right side of the water guide pipe 21, and a connecting pipe 23 is fixedly connected to the right side of the solenoid valve 22. A water delivery hose 24 is fixedly sleeved inside the connecting pipe 23. The other end of the water delivery hose 24 is distributed along the outer surface of the recycling box 4 and penetrates the positioning plate 6.

[0041] The solenoid valve 22 allows operators to easily control the water flow, enabling them to select between wet and dry vacuuming. When the device is turned on, the motor body 3 drives the fan blades 17 to rotate via the drive shaft 15 and fan blade connecting sleeve 16. The rotation of the fan blades 17 draws dust in through the protective cover 14 and filter plate 18, moving it along the inner wall of the sludge inlet trough 19 to the inside of the collection box 4 for temporary storage, and finally discharging it through the drain pipe 5. Turning on the solenoid valve 22 allows water from the water supply hose 24 to flow sequentially through the connecting pipe 23, solenoid valve 22, and water guide pipe 21 into the drain hole 20. When the water reaches the drain hole 20 in the motor body 3, it carries away the heat from the motor body 3, greatly improving its heat dissipation efficiency. Simultaneously, the water is sprayed out through the drain hole 20 from the filter plate 18 to dissolve foreign objects on the ground. The heated water further dissolves the adhering foreign objects, making them easier for the vacuum cleaner to pick up, thus improving the dust removal effect.

[0042] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
