Description

Technical Field

[0001] This utility model relates to the field of electric curtain technology, specifically a combined stator core for electric curtains based on blower-type dust removal. Background Technology

[0002] As people's living standards continue to improve, electric curtains are increasingly used in modern homes. As the core component of the motor, the performance of the electric curtain directly affects the curtain's usability. The stator core, as a key component of the motor, plays a crucial role in the motor's performance. Since electric curtains are installed near windows and are placed together with the curtains, they are very prone to accumulating dust, which can then enter the motor. In traditional electric curtain motors, the stator core usually adopts a conventional structure and does not have a dust removal function. During the motor's operation, the stator core usually generates heat due to magnetic induction and other reasons, attracting dust and other impurities from the curtains and window edges. If these impurities and dust enter the motor, they will not only cause accelerated wear but also affect the motor's heat dissipation, easily leading to a reduction in the motor's lifespan. Utility Model Content

[0003] The purpose of this invention is to provide a combined stator core for electric curtains based on blower-type dust removal, in order to solve the problem mentioned in the background art that dust can easily enter the motor, causing heat dissipation difficulties and reduced lifespan.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a combined stator core for electric curtains based on blower-type dust removal, comprising silicon steel sheets, a screw rod is installed through the outer surface of the silicon steel sheets, and the outer surface of the screw rod is in contact with the outer surface of the silicon steel sheets, the screw rod is evenly distributed on the outer surface of the silicon steel sheets, and the silicon steel sheets are in contact with each other, one end of the outer surface of the screw rod has a stepped design, and a frame is installed through the outer surface of the screw rod, and a rotating suction mechanism is provided between the frame and the screw rod.

[0005] Preferably, the rotating suction mechanism includes: a filter screen, which is embedded in the side surface of the frame, and the frame and the silicon steel sheet are concentrically designed; a plug-in fan blade is rotatably mounted on the outer surface of the frame, and the plug-in fan blade is located on the inner side of the frame, and the frame is engaged with a screw; a through hole is opened on the outer surface of the plug-in fan blade, and one side of the through hole of the plug-in fan blade is flat; the through hole of the plug-in fan blade is concentrically designed with the frame; a second locking nut is threaded on the outer surface of the end of the screw away from the silicon steel sheet, and the outer surface of the second locking nut is in contact with the outer surface of the frame.

[0006] By adopting the above technical solution, the frame can be fixed by the stepped design of the screw and the second locking nut, so that the motor rotor can be inserted into the plug-in fan blades after installation. As the rotor rotates, it drives the plug-in fan blades to rotate, allowing the outside air to be filtered through the filter screen before entering the inside of the housing. At the same time, the rotation of the plug-in fan blades can dissipate heat from the inside of the housing and allow the passing air to carry away smaller dust particles, reducing the impact of dust on the motor, reducing dust accumulation inside the stator, increasing heat dissipation, and extending the service life of the motor.

[0007] Preferably, the outer surface of the screw is fitted with a housing, and the outer surface of the housing is in contact with the outer surface of the screw, and the outer surface of the housing is in contact with the outer surface of the second locking nut.

[0008] By adopting the above technical solution, the outer shell can be installed and fixed by the screw and the second locking nut, so that the frame and the outer shell can fit tightly together, which facilitates installation and disassembly while ensuring firmness. At the same time, there is no need to worry about the air intake volume decreasing due to the misalignment of the outer shell and the frame.

[0009] Preferably, the outer surface of the screw is threaded with a first locking nut, and the first locking nut is located at both ends of the screw, with the outer surface of the first locking nut in contact with the outer surface of the silicon steel sheet.

[0010] By adopting the above technical solution, the silicon steel sheets can be clamped and installed through the first locking nut and screw, so that the silicon steel sheets can be connected more tightly. At the same time, the number of silicon steel sheets can be flexibly adjusted according to the size of the shell, which has high versatility.

[0011] Preferably, an air inlet is provided on one end of the outer surface of the housing, and the outer surface of the air inlet is aligned with the height of the filter screen. An exhaust port is provided on the outer surface of the housing away from the air inlet, and the exhaust port is not blocked by the outer surface of the silicon steel sheet. Furthermore, ventilation grooves are uniformly provided on the side surface of the silicon steel sheet.

[0012] By adopting the above technical solution, air can be drawn into the interior of the casing through the air inlet, and the heat generated by the silicon steel sheets during the operation of the stator can be carried away through the ventilation slot. At the same time, small dust particles can be carried away, so that the air that has absorbed heat can be discharged outward from the exhaust port.

[0013] Preferably, the outer surface of the silicon steel sheet is provided with grooves, and protruding teeth are provided between the grooves, with the screw located on one side of the grooves.

[0014] Using the above technical solution, the groove and the protruding teeth can be wound together, and the screw is located on one side of the groove so that the winding does not come into contact with the screw, reducing the short circuit caused by the winding contacting the screw during subsequent use.

[0015] Preferably, a slot is provided on the outer surface of the protruding tooth away from the outer shell, and a brush plate is inserted and installed on the outer surface of the slot, with the protruding tooth extending out from the side surface of the brush plate, and the outer surface of the brush plate is in contact with the side surface of the rotor.

[0016] Using the above technical solution, the brush plate can be installed through the slot, so that when the motor rotor is rotating, the brush plate can clean and wash the rotating rotor, so that dust will not adhere to the surface of the rotor and affect the heat dissipation of the rotor.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the combined stator core for electric curtains based on blower-type dust removal:

[0018] 1. When the motor rotates, the rotor will rotate with the plug-in fan blades that are connected to it, allowing external air to enter the inside of the casing through the air inlet. Dust particles in the air can be filtered through the filter screen, reducing the chance of dust entering when the motor is dissipating heat. The air brought in by the rotation of the plug-in fan blades can also carry away and expel fine dust particles. By allowing air to pass through the inside of the casing, the heat dissipation performance of the motor is improved, thus enhancing the motor's durability and service life.

[0019] 2. The silicon steel sheets can be clamped and fixed by locking the screw and the first locking nut, so that the silicon steel sheets can be connected more tightly and firmly. At the same time, the silicon steel sheets can be positioned relative to each other. When manufacturing motor stators of different specifications, silicon steel sheets can be added or reduced freely according to the specifications of the motor and the size of the housing, which improves the flexibility of stator manufacturing. It also facilitates the assembly of the frame, housing and screw, and allows the internal parts of the stator to be easily opened and replaced when damaged, which improves the convenience of manufacturing, maintenance, installation and disassembly.

[0020] 3. The brush plate can be inserted and fixed through the slot, allowing it to brush the rotating rotor surface to remove dust adhering to the rotor surface. Combined with the air drawn in by the rotating plug-in fan blades, the dust can be discharged outward from the exhaust port along the silicon steel sheet and ventilation slots, ensuring the cleanliness of the rotor surface and the inside of the stator. This improves the overall heat dissipation of the motor, while enhancing the stability and electromagnetic performance of the motor during operation. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-6 This utility model provides a technical solution: a combined stator core for electric curtains based on blower-type dust removal, including silicon steel sheets 1, with screws 2 installed through the outer surface of the silicon steel sheets 1, and the outer surface of the screws 2 being in contact with the outer surface of the silicon steel sheets 1. The screws 2 are evenly arranged on the outer surface of the silicon steel sheets 1, and the silicon steel sheets 1 are in contact with each other. One end of the outer surface of the screws 2 has a stepped design, and a frame 4 is installed through the outer surface of the screws 2. A rotating suction mechanism is provided between the frame 4 and the screws 2.

[0030] The screw 2 can be used to position all the inserted silicon steel sheets 1, and ensure that when the frame 4 is installed on the screw 2 by locking it with the second locking nut 7, the frame 4 and the second locking nut 7 can maintain a high degree of concentricity.

[0031] The rotating suction mechanism includes: a filter screen 5, which is embedded in the side surface of the frame 4, and the frame 4 and the silicon steel sheet 1 are concentrically designed. A plug-in fan blade 6 is rotatably installed on the outer surface of the frame 4, and the plug-in fan blade 6 is located on the inner side of the frame 4. The frame 4 is engaged with the screw 2. A through hole is opened on the outer surface of the plug-in fan blade 6, and one side of the through hole of the plug-in fan blade 6 is flat. The through hole of the plug-in fan blade 6 is concentrically designed with the frame 4. A second locking nut 7 is threaded on the outer surface of the end of the screw 2 away from the silicon steel sheet 1, and the outer surface of the second locking nut 7 is in contact with the outer surface of the frame 4.

[0032] When installing the rotor, it is inserted between the silicon steel sheets 1 and engages with the plug-in fan blades 6. The planar design of the through holes in the plug-in fan blades 6 allows the rotor to rotate along with the plug-in fan blades 6, enabling the plug-in fan blades 6 to draw in cool air from the outside into the housing 8. Dust in the air is filtered by the filter screen 5, and the rotation of the plug-in fan blades 6 blows away small dust particles, reducing the wear caused by dust entering the stator. It also blows away dust that has entered the housing 8, making it easy to clean the filter screen 5, improving the efficiency of motor heat dissipation, and extending the service life of the motor.

[0033] The outer surface of the screw 2 is fitted with the outer shell 8, and the outer surface of the outer shell 8 is in contact with the outer surface of the screw 2. The outer surface of the outer shell 8 is in contact with the outer surface of the second locking nut 7.

[0034] The second locking nut 7 can connect and fix the outer shell 8 and the screw 2 to each other. The insertion of the screw 2 and the outer shell 8 can prevent the air inlet 9 of the frame 4 and the outer shell 8 from being offset, thus reducing the complexity of the installation process and improving the stability of the motor after installation and use. At the same time, the combination method facilitates the replacement and maintenance of the internal components of the motor stator.

[0035] The screw 2 has a first locking nut 3 threaded on its outer surface, and the first locking nut 3 is located at both ends of the screw 2. The outer surface of the first locking nut 3 is in contact with the outer surface of the silicon steel sheet 1.

[0036] The silicon steel sheet 1 can be fixed and clamped by the screw 2 and the first locking nut 3, so that the silicon steel sheet 1 can be connected more firmly. At the same time, the number of silicon steel sheets 1 can be flexibly changed and adjusted according to the required motor specifications and the size of the housing 8, improving the versatility and convenience of assembly.

[0037] An air inlet 9 is provided on the outer surface of one end of the housing 8, and the outer surface of the air inlet 9 is aligned with the height of the filter screen 5. An exhaust port 10 is provided on the outer surface of the end of the housing 8 away from the air inlet 9, and the exhaust port 10 is not blocked by the outer surface of the silicon steel sheet 1. Ventilation grooves 13 are evenly provided on the side surface of the silicon steel sheet 1.

[0038] Air enters the interior of the housing 8 through the air inlet 9 by the rotation of the plug-in fan blade 6, and moves through the ventilation slot 13. The airflow through the gap between the ventilation slot 13 and the silicon steel sheet 1 allows fine dust particles in the air to be discharged out through the exhaust port 10, and the remaining dust particles are carried away by the wind.

[0039] The outer surface of the silicon steel sheet 1 is provided with a groove 11, and protruding teeth 12 are provided between the grooves 11. The screw 2 is located on one side of the groove 11.

[0040] The design of the screw 2 being located on one side of the groove 11 can effectively prevent the winding from contacting the screw 2, so that the winding wound on the protruding tooth 12 will not be damaged by short circuit due to friction with the screw 2.

[0041] A slot 14 is provided on the outer surface of the protruding tooth 12 away from the outer shell 8, and a brush plate 15 is inserted and installed on the outer surface of the slot 14. The side surface of the brush plate 15 extends out of the protruding tooth 12, and the outer surface of the brush plate 15 is in contact with the side surface of the rotor.

[0042] The brush plate 15 can be installed through the slot 14, so that when the rotor is rotating, the brush plate 15 can brush the side surface of the rotor, so that dust and other debris will not remain on the outer surface of the rotor, improving the heat dissipation of the motor, and enhancing the stability and electromagnetic performance of the motor during operation.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
