Description

Technical Field

[0001] The invention relates to the technical field of water stirring motors, in particular to a handicraft water lamp with a sealed magnetic levitation motor. Background Art

[0002] Brushed motors have fast response, large starting torque, and the ability to provide rated torque from zero speed to rated speed. However, the advantages of DC motors are also its disadvantages. In order for brushed motors to produce constant torque under rated load, the armature magnetic field and the motor rotor magnetic field must be constantly maintained at 90°, which requires carbon brushes and commutators. Carbon brushes and commutators will generate sparks and carbon powder when the motor rotates, which will not only cause component damage, but also limit the occasions of use. It is precisely because traditional motors are noisy and carbon brushes are easy to break, so technicians in this field are urgently needed to develop motors with superior performance.

[0003] The water stirring motor is one of the indispensable and important components in the handicraft water lantern. Due to the particularity of its working environment, the installation sealing of the water stirring motor is very important. However, the existing water stirring motor for handicraft water lanterns is a separate motor with poor installation sealing. Some of them have water seepage problems. Once water enters the water stirring motor, it will directly affect the normal operation of the handicraft water lantern. In severe cases, it will directly lead to the scrapping of the water stirring motor. There are also some water stirring motors in handicraft water lanterns. Although there is no problem of water seepage, the water stirring motor itself is an open assembly, which will generate a lot of noise during operation, directly affecting the user experience of the handicraft water lantern.

[0024] The brushless motor 5 is fixed to the bottom of the water sealing platform 2 through an inner fixed shaft 6 .

[0025] See Figure 1 and Figure 2 The present invention discloses a handicraft water lamp with a sealed magnetic levitation motor. The handicraft water lamp comprises an inner shell 7 and an interior viewing platform 8 arranged in the inner shell 7. The interior viewing platform 8 can be replaced at will. The interior viewing platform 8 is a person, an animal or a plant, etc. The water sealing platform 2 is installed at the bottom of the inner shell 7, and the water impeller 1 is connected to the interior viewing platform 8.

[0026] The bottom of the water sealing platform 2 is provided with a sealing installation groove 2 - 1 which is recessed upward, and the brushless motor 5 is embedded in the sealing installation groove 2 - 1 .

[0027] The interior view platform 8 is arranged in the inner liner cover 7 through the interior view card platform 9. The interior view card platform 9 and the interior view platform 8 are matched with a card block 9-1 and a card hole 8-1. The card block 9-1 is matched and embedded in the card hole 8-1 to achieve a quick card connection between the interior view card platform 9 and the interior view platform 8.

[0028] An upper positioning hole 9-2 is provided on the inner scene card platform 9, a middle positioning hole 1-1 is provided on the water pumping impeller 1, and a lower positioning hole 2-2 is provided on the water sealing platform 2. The middle positioning hole 1-1 is a cylindrical through hole, and the upper positioning hole 9-2 is a blind hole with a sealed upper portion and an open lower portion.

[0029] After the interior scene fixed shaft 6 passes through the middle positioning hole 1-1, the upper part of the interior scene fixed shaft 6 is inserted and fixed in the upper positioning hole 9-2, and the lower part of the interior scene fixed shaft 6 is inserted and fixed in the lower positioning hole 2-2. That is, after the interior scene fixed shaft 6 passes through the water-pumping impeller 1, the upper part of the interior scene fixed shaft 6 is fixedly connected to the interior scene card platform 9, and the lower part of the interior scene fixed shaft 6 is fixedly connected to the water sealing platform 2.

[0030] The water pumping impeller 1 comprises a Π-shaped impeller body 1-2, the inner diameter of the impeller body 1-2 is the same as the outer diameter of the magnetic ring 3, and the magnetic ring 3 is embedded in the inner wall of the impeller body 1-2.

[0031] The outer diameter of the sealing installation groove 2 - 1 is the same as the inner diameter of the magnetic ring 3 , and the magnetic ring 3 is sleeved on the outside of the sealing installation groove 2 - 1 to achieve the rotational assembly of the water pumping impeller 1 and the water sealing platform 2 .

[0032] A plurality of rotating water-pumping blades 1-3 are evenly arranged in the circumferential direction on the top of the impeller body 1-2, and the angles of the plurality of rotating water-pumping blades 1-3 are respectively set to facilitate the rotation of the liquid in the inner tank cover 7.

[0033] The outer edge of the water sealing platform 2 and the outer edge of the inner liner cover 7 are matched with a slot 2-3 and a buckle 7-1. The buckle 7-1 is matched and embedded in the slot 2-3 to achieve quick assembly between the water sealing platform 2 and the inner liner cover 7. The slot 2-3 is filled with a water sealing silicone ring 10 to prevent the liquid in the inner liner cover 7 from leaking out.

[0034] The upper cross-section of the sealing installation groove 2-1 is circular, and the lower positioning hole 2-2 is arranged at the center of the top of the sealing installation groove 2-1, and the lower positioning hole 2-2 is a blind hole with an upper opening and a lower sealing.

[0035] The sealing installation groove 2-1, the lower positioning hole 2-2 and the card slot 2-3 are an integrated structure.

[0036] The bottom of the water sealing platform 2 is also provided with a water sealing port, and a water sealing plug is added to the water sealing port, which can seal the liquid in the inner liner cover 7 to prevent the liquid in the inner liner cover 7 from leaking out. When the liquid in the inner liner cover 7 needs to be discharged or replaced, the water sealing plug can be pulled out, so that the liquid in the inner liner cover 7 will be discharged from the water sealing port.

[0037] The brushless motor 5 includes a motor rotor and a motor stator, wherein the motor rotor is located outside the motor stator. The main function of the motor rotor is to be cut by magnetic lines of force in a rotating magnetic field to generate output current. The motor stator is the stationary part, and the main function of the motor stator is to generate a rotating magnetic field.

[0038] The motor rotor is composed of four relatively independent quarter-circular cylindrical structures, which can form a hollow cylinder. The four relatively independent quarter-circular cylindrical structures include two N poles and two S poles, and the N poles and the S poles are alternately distributed.

[0039] The motor stator includes a motor stator core, four yokes and four teeth. The four yokes and the four teeth are connected along the radial direction of the motor stator core, and the yokes are located on the outside of the teeth. The four teeth are evenly arranged in the radial direction of the motor stator core, and there is a yoke on the outside of each tooth.

[0040] The outer arc surface of the yoke is formed by continuously splicing multiple arc surfaces. During the rotation of the motor rotor, the gap between the motor rotor and the yoke will change. During the clockwise rotation of the motor rotor, at the same position, the gap between the motor rotor and the yoke gradually becomes smaller. During the counterclockwise rotation of the motor rotor, at the same position, the gap between the motor rotor and the yoke gradually becomes larger.

[0041] The sealed magnetic levitation motor adopts the method of combining a motor with a water sealing platform 2, and the motor is divided into two parts: a brushless motor 5 and a magnetic ring 3. The brushless motor 5 and the magnetic ring 3 are respectively separated at the upper and lower parts of the water sealing platform 2. When the brushless motor 5 is energized, the magnetic ring 3 is triggered to rotate. Since there is a water-pumping impeller 1 outside the magnetic ring 3, the water-pumping impeller 1 rotates to achieve a water stirring effect. That is, the brushless motor 5 and the magnetic ring 3 can rotate through the plastic water sealing platform 2, with high sealing performance, long service life and no noise.

[0042] The handicraft water lantern has a good user experience, no noise, and a long overall service life.
