The conveniently replaceable working head (such as a massage head) can improve the switching efficiency of the handheld device's working device and improve the use effect of the handheld device.

[0030] A multi-purpose driving device based on a brushless motor provided in an embodiment of the present application is described in detail below with reference to specific examples.

[0031] Figure 1 A three-dimensional schematic diagram of a multi-purpose drive device based on a brushless motor provided in an embodiment of the present application, Figure 2 A schematic top view of a multi-purpose drive device based on a brushless motor provided in an embodiment of the present application. Figure 3 for Figure 2 A schematic diagram of the AA cross-sectional structure of a multi-purpose drive device based on a brushless motor is shown in FIG. Figures 1 to 3 As shown, the multi-purpose driving device based on the brushless motor includes a connecting disk 1, a fixed head 2 and a handle 3. The fixed head 2 is provided with a brushless motor 21. The stator 211 of the brushless motor 21 is fixedly connected in the fixed head 2. The rotor 212 of the brushless motor 21 can rotate in the fixed head 2. The connecting disk 1 is connected to the rotor 212. The fixed head 2 and the handle 3 are integrally arranged. The handle 3 is provided with a battery assembly and a control assembly electrically connected to the brushless motor 21.

[0032] like Figures 1 to 3 As shown, the fixed head 2 in the multi-purpose driving device is used for fixing and installing the working structure. A brushless motor 21 is arranged inside the fixed head 2. The brushless motor 21 is a power component of the driving device.

[0033] Functionally, the fixed head 2 is used to fix the brushless motor 21. The stator 211 of the brushless motor 21 is fixedly connected in the fixed head 2. The rotor 212 of the brushless motor 21 can rotate in the fixed head 2. During operation, the stator 211 drives the rotor 212 to rotate in the fixed head 2.

[0034] Functionally, the connecting disk 1 is a structure for fixing the working head. The connecting disk 1 is connected to the rotor 212 so that the connecting disk 1 can rotate together with the rotor 212, thereby driving the working head on the connecting disk 1 to rotate.

[0035] like Figure 1 and Figure 2 As shown, the fixed head 2 and the handle 3 are integrally arranged, and the handle 3 is used to facilitate holding the driving device.

[0036] Structurally, a battery assembly and a control assembly electrically connected to the brushless motor 21 are provided in the handle 3. The brushless motor 21 can be powered by the battery assembly, and the working state of the brushless motor 21 can be controlled by the control assembly.

[0037] like Figure 1 As shown, the connection plate 1 is used to install a fan head or a massage head, so that the drive device can be used as a fan in conjunction with the fan head, or the drive device can be used as a massager in conjunction with the massage head.

[0038] like Figures 1 to 3 As shown, the connecting disk 1 includes a disk body 11, a ring body 12 and a plurality of ring body blocks 13, wherein the disk body 11 is the main structure of the connecting disk 1, and the ring body 12 and the plurality of ring body blocks 13 are structures for fixing the working head.

[0039] Structurally, the disc body 11 is circular, so that the resistance of the disc body 11 during rotation is small.

[0040] like Figure 1 As shown, the ring body 12 protrudes from the circumference of the disk body 11, and the ring body 12 is used to limit the working head from the circumference. A plurality of ring body blocks 13 protrude from the disk body 11 and are arranged in an array on the inner side of the ring body 12. The plurality of ring body blocks 13 can cooperate with the working head to transmit torque to the working head, so that the ring body 12 and the ring body blocks 13 can cooperate with each other to fix the working head.

[0041] During use, when the working head needs to be replaced, it is only necessary to remove the working head from the ring body 12 and the ring body block 13, without removing the fixing structure such as screws. When installing the working head, it is only necessary to clamp the working head to the ring body 12 and the ring body block 13, thereby realizing the clamping and fixing of the ring body 12 and the ring body block 13, without installing the fixing structure such as screws.

[0042] The beneficial effect brought about by the above-mentioned implementation method is that it is only necessary to clamp the working head (such as a fan head or a massage head) onto the working disk without using additional fixing structures such as screws, thereby improving the convenience of using the driving device.

[0043] In some implementations, the number of the circle body blocks 13 is 3, and the 3 circle body blocks 13 are evenly arranged on the circle body 12. Each circle body block 13 extends in a straight line from the circle body 12 to the center of the disk body 11, and each circle body block 13 gradually narrows from the circle body 12 to the center of the disk body 11, and the end of each circle body block 13 is an arc structure.

[0044] like Figure 1 and Figure 2As shown, in terms of structure, there are three ring body blocks 13, which are evenly arranged on the ring body 12, so that the three ring body blocks 13 can cooperate with each other to lock the working head, thereby realizing power transmission to the working head.

[0045] Structurally, each ring block 13 extends in a straight line from the ring body 12 to the center of the disk body 11, so that the ring block 13 can transmit torque in the length direction from the ring body 12 to the center of the disk body 11, thereby improving the stability and reliability of the torque transmitted by the ring block 13.

[0046] Structurally, each circle body block 13 gradually narrows from the circle body 12 to the center of the disk body 11, so that the volume occupied by the circle body block 13 gradually decreases from the circle body 12 to the center of the disk body 11, making it easier to clamp the working head between multiple circle body blocks 13, thereby improving the convenience of clamping the working head.

[0047] Structurally, the end of each ring body block 13 is in an arc structure, which facilitates adjustment of the position of the working head on the ring body block 13 and improves the convenience of adjusting the ring body block 13 .

[0048] The beneficial effect brought about by the above implementation method is that the volume occupied by the ring body blocks gradually decreases from the ring body to the center of the disk body, which makes it easy to clamp the working head between the multiple ring body blocks.

[0049] The beneficial effect brought about by the above implementation method is that the end of each ring body block is in an arc structure, which improves the convenience of adjusting the ring body block.

[0050] In some implementations, a disk body positioning block 111 and a plurality of disk body clamping blocks 112 are provided in the middle of the disk body 11 . The disk body positioning block 111 is circular, and the plurality of disk body clamping blocks 112 are arranged in an array on the circumference of the disk body positioning block 111 .

[0051] like Figure 1 and Figure 2 As shown, structurally, a tray body positioning block 111 and a plurality of tray body clamping blocks 112 are provided in the middle of the tray body 11 , and the tray body positioning block 111 and the plurality of tray body clamping blocks 112 are used to further position the working head from the middle of the tray body 11 .

[0052] In terms of structure, the disk body positioning block 111 is circular, which makes it easy to adjust the relative position between the disk body positioning block 111 and the working head. A plurality of disk body clamping blocks 112 are arranged in an array on the circumference of the disk body positioning block 111, so that the plurality of disk body clamping blocks 112 can cooperate with the working head on the circumference of the disk body positioning block 111 to position the working head, thereby improving the stability of the working head.

[0053] The beneficial effect brought about by the above implementation method is that the disc body positioning block and the plurality of disc body clamping blocks can further position the working head from the middle of the disc body, thereby improving the stability of the working head.

[0054] In some implementations, the height of the disk body block 112 is lower than the height of the ring body block 13 .

[0055] like Figure 1 As shown, in terms of structure, the height of the disk block 112 is lower than the height of the ring block 13, so that the volume occupied by the disk block 112 is smaller, which increases the installation space of the working head when installing the working head, and facilitates the clamping of the working head. In particular, for the working head made of silicone or rubber material, it can improve the convenience of installing the working head on the connecting disk 1.

[0056] The beneficial effect brought about by the above-mentioned implementation method is that the volume occupied by the disc block is reduced, and for a working head made of silicone or rubber material, the convenience of installing the working head on the connecting disc can be improved.

[0057] In some implementations, the number of the disk body blocks 112 is three, and the disk body blocks 112 and the ring body blocks 13 are arranged at the same angle on the disk body 11 .

[0058] like Figure 2 As shown, structurally, the disc body block 112 and the ring body block 13 are arranged at the same angle on the disc body 11, so that the disc body block 112 and the ring body block 13 can cooperate with each other at the same angle to position the working head, thereby improving the stability of the working head.

[0059] The beneficial effect brought about by the above implementation method is that the disc body clamping block and the ring body clamping block cooperate with each other at the same angle to position the working head, thereby improving the stability of the working head.

[0060] In some implementations, each disk body block 112 extends from an edge of the disk body positioning block 111 toward a ring body block 13 , and the end of each disk body block 112 is in an arc structure.

[0061] like Figure 2 As shown, structurally, each disk body block 112 extends from the edge of the disk body positioning block 111 to a ring body block 13, so that each disk body block 112 positions the working head outward from the edge of the disk body positioning block 111, thereby increasing the force-bearing length of each disk body block 112 and improving the stability of the disk body block 112 in positioning the working head.

[0062] Structurally, the end of each disk block 112 is in an arc structure, which is convenient for adjusting and clamping the working head, thereby improving the convenience of installing the working head.

[0063] The beneficial effect brought about by the above implementation method is that the force-bearing length of each disc body block is increased, and the stability of the disc body block in positioning the working head is improved.

[0064] The beneficial effect brought about by the above implementation method is that the arc structure at the end of the disc body clamping block facilitates the adjustment and clamping of the working head, thereby improving the convenience of installing the working head.

[0065] In some implementations, a mounting hole 112 a is provided at the end of each disk block 112 , and the mounting hole 112 a is used for mounting screws to connect and fix the rotor 212 .

[0066] like Figure 2 and Figure 3 As shown, the mounting hole 112 a is used for mounting screws to connect and fix the rotor 212 . The connecting disk 1 and the rotor 212 can be connected and fixed through the mounting hole 112 a , so that the connecting disk 1 can rotate under the drive of the rotor 212 .

[0067] The beneficial effect brought about by the above implementation method is that the mounting hole is arranged on the disc body block, so that the disc body block can position the working head and install the screw at the same time, thereby improving the integration of the driving device.

[0068] In some implementations, a step structure 121 formed by a depression is provided on the outer side of the ring body 12 in the circumferential direction.

[0069] Figure 4 for Figure 3 A schematic diagram of the local structure of a multi-purpose drive device based on a brushless motor at B, as shown in FIG. Figure 4 As shown, a concave step structure 121 is provided on the outer side of the ring body 12 in the circumferential direction, so that the working head can be sleeved and connected to the ring body 12 with the step structure 121. The step structure 121 can improve the stability of the connection between the working head and the connecting disk 1.

[0070] The beneficial effect brought about by the above-mentioned implementation method is that the working head can be sleeved and connected to the ring body with a step structure, thereby improving the stability of the fixation of the working head; the working head can be clipped onto the connecting disk and the disk body positioning block, multiple disk body clip blocks, and the disk body positioning block are respectively clipped and positioned, thereby improving the installation stability of the working head.

Among them, the massage head made of silicone has a certain elasticity, which can easily realize the mutual connection between the massage head and the disc body.
