Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to an appliance base. Background Technology

[0002] A standing physiotherapy lamp is a rehabilitation and nursing medical device used for infrared physiotherapy. Existing standing physiotherapy lamps are typically floor-standing or tabletop models. These lamps usually have their power cord routed from the controller to an external socket, leaving the cord suspended in the air. However, this requires caregivers to frequently move and transport the lamp to the affected area. Without careful monitoring of the cord's position, caregivers are prone to tripping and getting tangled in the cord, leading to inconvenience. Furthermore, existing standing physiotherapy lamps are relatively heavy, especially when not upright, creating a significant torque that can cause them to tip over, potentially injuring those nearby or even damaging themselves.

[0067] like Figure 4 As shown, according to one embodiment of the present invention, a first positioning structure 121 for fitting and matching with the base body 11 is provided on the lower side of the base cover 12. In this embodiment, the first positioning structure 121 and the outer edge of the base cover 12 are spaced apart. Thus, when the first positioning structure 121 fits and matches with the corresponding structure of the base body 11, the edge of the base cover 12 abuts against the upper end of the base body 11, thereby sealing the upper end of the base body 11 with the base cover 12, effectively preventing external dust or moisture from seeping in from the connection position, and effectively ensuring the overall sealing of the base.

[0068] In this embodiment, the first positioning structure 121 includes a first positioning part 121a and a second positioning part 121b.

In this embodiment, if the first positioning portions 121a in the multiple first positioning structures 121 are fixedly connected to each other, the first positioning portions 121a can form a ring coaxial with the base cover 12, thereby further strengthening the edge structure of the base cover 12 and ensuring the structural strength and stability of the entire base cover 12.

[0072] like Figure 4As shown, according to one embodiment of the present invention, a first reinforcing rib structure 122 is provided on the lower side of the base cover 12; wherein, the first reinforcing rib structure 122 is arranged in the area between the first positioning structure 121 and the annular enclosure 12a1.

In this embodiment, the counterweight plate 14 is detachably connected to facilitate its manufacturing and installation. In addition, in another embodiment, the counterweight plate 14 can be integrated into the base body 11 and / or the base cover 12 to achieve a simplified and compact structure, wherein the material of the counterweight plate 14 can be the same as the material of the base body 11 and / or the base cover 12, or it can be different, and can be adapted according to the corresponding actual needs.

[0074] Combination Figure 4 and Figure 5As shown, according to one embodiment of the present invention, a positioning connecting post 12c for connecting to the base body 11 is further provided on the lower side of the base cover 12. The lower side of the positioning connecting post 12c may be provided with a threaded hole for connecting a threaded connector. In this embodiment, the axial length of the positioning connecting post 12c exceeds the height of the first reinforcing rib structure 122. Therefore, the positioning connecting post 12c can be used to achieve an engagement connection with the hole on the counterweight plate 14, thereby achieving the positioning and assembly of the counterweight plate 14.

[0075] Combination Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, according to one embodiment of the present invention, the base body 11 includes: a base plate 111, and an annular outer perimeter 112 disposed on the edge of the base plate 111; wherein, a second positioning structure 1121 is disposed on the inner side of the annular outer perimeter 112, wherein the second positioning structure 1121 and the annular outer perimeter 112 form a fitting groove for the first positioning structure 121 to be inserted; in this embodiment, the inner side of the first positioning part 121a abuts against the second positioning structure 1121, and the outer side of the second positioning part 121b abuts against the inner side of the annular outer perimeter 112.

[0077] With the above configuration, the annular outer ring 112 is set as a conical ring structure with a larger upper end and a smaller lower end. On the one hand, this makes the base of this utility model more aesthetically pleasing. On the other hand, it ensures that the base cover 12 is completely covered by the base body 11 after installation. As a result, the base of this utility model has excellent waterproof effect, allowing liquid dripping on the base cover 12 to flow directly from the edge of the base cover 12 to the ground, effectively preventing liquid dripping on the base cover 12 from seeping into the base from the connection point.

[0078] Combination Figure 2 , Figure 6 and Figure 7 As shown, according to one embodiment of the present invention, a second notch 112a is provided on the annular outer perimeter 112 to allow cables to be led out. In this embodiment, the second notch 112a is positioned higher than the circuit board 13. Thus, the cables to be led out can be connected from above the circuit board 13 and led out, so that the circuit board 13 is at a certain height from the ground. This helps to avoid wear between the relatively concealed parts of the cable and the ground, and is more beneficial to ensuring the safety of the present invention.

[0082] Combination Figure 2 and Figure 3 As shown, according to one embodiment of the present invention, after the base body 11 and the base cover 12 are installed together, the first reinforcing rib structure 122 and the second reinforcing rib structure 1112 abut against the upper and lower sides of the counterweight plate 14 respectively, thereby ensuring that the counterweight plate 14 is installed reliably.

[0083] According to one embodiment of this utility model, the circuit board 13 includes a power supply board and a control board, wherein the power supply board and the control board can be separately configured or integrated. In this embodiment, the control board can be implemented using a microcontroller control board, etc., which will not be described in detail here. Of course, the circuit board 13 can also optionally be equipped with a switch structure to achieve selective control of preset functions, wherein the switch structure can be implemented using existing mature mechanical switch devices, touch switch devices, etc., which will not be described in detail here.

[0084] According to one embodiment of this utility model, the electrical appliance base of this utility model can be further provided with a cable storage mechanism, wherein the cable storage mechanism includes: a rotating shaft, a storage wheel, and a torsion spring; wherein the storage wheel is rotatably connected to the rotating shaft, and the torsion spring is also sleeved on the rotating shaft. In this embodiment, the end of the rotating shaft is rotatably connected to the base body 11 and / or the base cover 12, thereby realizing the rotational installation of the rotating shaft. Furthermore, one connecting arm of the torsion spring is fixedly connected to the base body 11 or the base cover 12, and the other connecting arm is connected to the storage wheel, thereby achieving the cable storage effect by rotating the storage wheel. Specifically, the cable is connected to the storage wheel by winding, thereby driving the storage wheel to rotate when the cable is pulled, and then the rotation of the storage wheel compresses the torsion spring; when the cable is released, the elastic recovery effect of the torsion spring drives the storage wheel to rotate in the opposite direction, thereby achieving automatic cable retraction. In this embodiment, the cable storage mechanism is arranged adjacent to the circuit board 13 to achieve a compact structural layout.
