Description

Technical Field

[0001] This invention relates to the field of nail lamp technology, and in particular to a micro switch. Background Technology

[0002] Nail lamps are specifically used for drying UV gel in the nail art process. During a nail art procedure, a layer of UV gel, similar to nail polish but less prone to peeling, is applied to the nails and then dried using a nail lamp. Nail lamps generally come in two types: UV lamps and LED lamps, but they all work by using the heat from the lamp's light to bake the UV gel.

[0003] Traditional nail lamps, such as Figure 1 As shown, the device includes a hand pad (1) and a lampshade (2). The lampshade (2) integrates multiple lamp heads for drying the gel polish on the fingers. However, the nail lamp lacks a microswitch that can adaptively adjust to the user's hand to ensure even drying of the gel polish. For example, when the user inserts their right hand, the four fingers are pointing upwards, and the lamp head is pointing downwards, allowing for good drying. However, the right thumb is pointing to one side, and the downward-facing lamp head often misses it, so the thumb typically dries slower than the other nails. Summary of the Invention

[0004] The technical problem to be solved by this invention is how to enable a nail lamp to evenly heat five fingers, and a micro switch is provided.

[0005] The technical solution of the present invention is a micro switch, comprising a turntable rotatably connected to the center of a hand pad, with a first lens clamp and a second lens clamp respectively provided on both sides of the turntable. The opening direction of the first lens clamp and the second lens clamp is towards the position of the turntable. Each of the first lens clamp and the second lens clamp includes a first lens and a second lens hinged to each other. The first lens and the second lens are connected by a self-holding elastic hinge shaft, so that the first lens can remain in a covered state when it is covered relative to the second lens. The side of the first lens and the second lens facing each other is a mirror surface. The first lens and the second lens are respectively provided with a constricted upper top groove and a constricted lower top groove, which together form a top hole for a top ball to enter. A first steel wire rope and a second steel wire rope extending to the first lens clamp and the second lens clamp are wound on the turntable. The first and second steel wire ropes are wound in opposite directions on the turntable. A top ball is located at the end of the first and second steel wire ropes. The first and second steel wire ropes are embedded in a rope groove opened on the hand pad. A return spring is also provided in the rope groove and sleeved on the outside of the first and second steel wire ropes. A rotating cavity is opened in the hand pad below the turntable. A reel is rotatably connected in the rotating cavity. A first pull line and a second pull line are wound on the reel. The first and second pull lines are wound in the same direction on the reel. The first and second pull lines are connected to the second lens of the first lens clamp and the second lens of the second lens clamp respectively through a wire groove opened on the hand pad. A lifting column is also provided in the middle of the reel and rises as the reel rotates.

[0006] In one embodiment, a rotating groove is provided in the middle of the hand pad, and the turntable is rotatably connected in the rotating groove.

[0007] In one embodiment, the rope groove is connected to the rotating groove.

[0008] In one embodiment, the turntable includes an upper rotating plate, a middle disc, and a lower rotating plate connected in sequence. The lower rotating plate is rotatably connected in the rotating groove. The first steel wire rope and the second steel wire rope are wound on the middle disc. The upper rotating plate completely covers the rotating groove.

[0009] In one embodiment, one end of the return spring is fixed to the opening of the rope groove facing the first or second mirror clamp, and the other end of the return spring is fixed to the outside of the first or second steel wire rope; wherein, when the turntable is rotated in different directions, the top ball on the first or second steel wire rope can be controlled to extend; when the turntable is released, the top balls on the first and second steel wire ropes are reset under the action of the return springs on both sides.

[0010] In one implementation, the return springs on both sides are of the same specification.

[0011] In one implementation, the elastic hinge shaft is provided at two locations.

[0012] In one embodiment, the reel is an I-shaped disc with a hollow center and a spirally engaged with a lifting column passing through its center. When the first lens clamp is opened, the reel is rotated by the first pull line, thereby causing the lifting column to rise. When the second lens clamp is opened, the reel is rotated by the second pull line, thereby causing the lifting column to rise. Pressing the lifting column to return it to its original position can control the first lens clamp cover to be closed by the first pull line or the second lens clamp cover to be closed by the second pull line.

[0013] In one implementation, both the first pull wire and the second pull wire are flexible wires.

[0014] In one embodiment, the rotating cavity is used to accommodate the first or second pull wire that has been unwound.

[0015] The advantage of this invention compared to existing technologies is that the opening of either the first or second lens clip can be controlled by a slight rotation of a microswitch. When baking nails, the user needs to slightly rotate the turntable. Both the first and second steel wire ropes wound on the turntable are rigid, so the first wire rope can extend, while the second wire rope can retract. This retraction does not cause the second lens clip to open, but the extension causes the top ball to extend into the top hole. When the top ball extends, it can separate the upper and lower top grooves that were originally joined together. This causes the first lens clip to open, and the first and second lenses of the first lens clip slowly open under the action of the elastic hinge shaft, eventually reaching a certain opening angle. The surfaces of the first and second lenses facing each other are mirrored. After opening, the lamp head shines light onto the first lens, which is then reflected onto the second lens, ultimately illuminating the user's thumb. Because return springs are provided at both locations, the turntable can automatically return to its original position after rotation. Furthermore, during the opening of the first or second lens clip, the reel can be rotated via the first or second pull cable. This reel is located within the rotating cavity and engages with the lifting column via a screw mechanism. That is, rotating the reel causes the lifting column to rise. Similarly, pressing the lifting column back to its original position causes the reel to rotate, thereby closing the first or second lens clip via the first or second pull cable. The above describes the entire process of using the microswitch once. When in use, the reel should be rotated slightly; when not in use, the lifting column should be pressed. The purpose is to allow the user's fingernails to be evenly heated. Attached Figure Description

[0022] The above and other embodiments and advantages of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0023] In one implementation, such as Figure 2-5 As shown.

[0024] The micro switch provided in this embodiment includes a turntable 3 rotatably connected to the middle position of a hand pad 1. A first mirror clip 4 and a second mirror clip 5 are respectively provided on both sides of the turntable 3. The opening direction of the first mirror clip 4 and the second mirror clip 5 is towards the position of the turntable 3. Each of the first mirror clip 4 and the second mirror clip 5 includes a first mirror 6 and a second mirror 7 hinged to each other. The first mirror 6 and the second mirror 7 are connected by a self-holding elastic hinge shaft 8, so that the first mirror 6 can remain closed when it is closed relative to the second mirror 7. The side of the first mirror 6 and the second mirror 7 facing each other is a mirror surface. The first mirror 6 and the second mirror 7 are respectively provided with a constricted upper top groove 9 and a constricted lower top groove 10. The upper top groove 9 and the lower top groove 10 together form a top hole 12 into which a top ball 11 extends. A first steel wire rope 13 and a second steel wire rope 14 extending to the first mirror clip 4 and the second mirror clip 5 are wound on the turntable 3. The winding directions of the steel wire rope 13 and the second steel wire rope 14 on the turntable 3 are opposite. The top ball 11 is located at the end of the first steel wire rope 13 and the second steel wire rope 14. The first steel wire rope 13 and the second steel wire rope 14 are embedded in the rope groove 15 opened on the hand pad 1. The rope groove 15 is also provided with a return spring 16 sleeved on the outside of the first steel wire rope 13 and the second steel wire rope 14. The hand pad 1 has a rotating cavity 17 located below the turntable 3. The rotating cavity 17 is rotatably connected to the reel 18. The reel 18 has a first pull line 19 and a second pull line 20 wound on it. The first pull line 19 and the second pull line 20 are wound in the same direction on the reel 18. The first pull line 19 and the second pull line 20 are connected to the second lens 7 of the first lens clip 4 and the second lens 7 of the second lens clip 5 respectively through the wire groove 21 opened on the hand pad 1. The hand pad 1 is also provided with a lifting column 22 located in the middle of the reel 18 and rising as the reel 18 rotates.

[0025] In this embodiment, the first lens clip 4 or the second lens clip 5 can be opened by slightly rotating the micro switch. When the nails are being heated, if the right hand is inserted, the nail lamp head will generally light up upon insertion. Additionally, the user needs to slightly rotate the turntable 3 to the left. The first steel wire rope 13 and the second steel wire rope 14 wound on the turntable 3 are both rigid ropes, so the first steel wire rope 13 can extend, while the second steel wire rope 14 can retract. This retraction does not cause the second lens clip 5 to open, but the extension causes its top ball 11 to extend into the top hole 12. Figure 3 As shown, the top hole 12 consists of two parts: a narrowed upper top groove 9 and a narrowed lower top groove 10. Therefore, when the top ball 11 is inserted, it can separate the upper top groove 9 and the lower top groove 10, which were originally joined together. This causes the first mirror clip 4 to open. The first mirror 6 and the second mirror 7 of the first mirror clip 4 slowly open under the action of the elastic hinge shaft 8, eventually reaching a certain opening angle. The sides of the first mirror 6 and the second mirror 7 facing each other are both mirror surfaces. After opening, the placed lamp head shines light onto the first mirror 6, which is then reflected onto the second mirror 7, ultimately illuminating the user's thumb.

[0026] Similarly, if the left hand is inserted, the nail lamp head will generally light up upon insertion. Additionally, the user needs to slightly rotate the turntable 3 to the right. The first steel wire rope 13 and the second steel wire rope 14 wound on the turntable 3 are both rigid ropes, so the second steel wire rope 14 can extend, while the first steel wire rope 13 can retract. This retraction does not cause the first lens clip 4 to open, but the extension causes its top ball 11 to extend into the top hole 12. (The last sentence appears to be incomplete and possibly refers to a different process.) Figure 3 As shown, the top hole 12 consists of two parts: a narrowed upper top groove 9 and a narrowed lower top groove 10. Therefore, when the top ball 11 is inserted, it can separate the upper top groove 9 and the lower top groove 10, which were originally joined together. This causes the second mirror clip 5 to open. The first mirror 6 and the second mirror 7 of the second mirror clip 5 slowly open under the action of the elastic hinge shaft 8, eventually reaching a certain opening angle. The sides of the first mirror 6 and the second mirror 7 facing each other are both mirror surfaces. After opening, the placed lamp head shines light onto the first mirror 6, which is then reflected onto the second mirror 7, ultimately illuminating the user's thumb.

[0027] Because return springs 16 are installed at both locations, the turntable 3 can automatically reset after rotation. Furthermore, during the opening of the first lens clip 4 or the second lens clip 5, the reel 18 can be rotated via the first pull cable 19 or the second pull cable 20. This reel 18 is located within the rotating cavity 17 and is screwed into the lifting column 22. That is, the rotation of the reel 18 can be converted into the rising of the lifting column 22. Similarly, pressing the lifting column 22 to return it to its original position can drive the rotation of the reel 18, thereby closing the first lens clip 4 or the second lens clip 5 via the pull cable 19 or the second pull cable 20. The above describes the entire process of using the microswitch once. When in use, the turntable 3 should be slightly rotated; when not in use, the lifting column 22 should be pressed. The purpose is to allow the user's fingernails to be evenly heated.

[0028] In one implementation, such as Figure 2 As shown.

[0029] The micro switch provided in this embodiment has a rotating groove 23 in the middle of the hand pad 1, and the turntable 3 is rotatably connected in the rotating groove 23.

[0030] In this embodiment, a rotating groove 23 is provided on the surface of the hand pad 1. The function of this rotating groove 23 is to accommodate the rotating disk 3. Therefore, considering the use of both left and right hands, the rotating groove 23 is located in the middle of the hand pad 1. Figure 2 The turntable 3 shown exposes the rotating groove 23 to showcase the first steel wire rope 13 and the second steel wire rope 14. In a preferred embodiment, the turntable 3 includes an upper rotating plate 24, a middle disc 25, and a lower rotating plate 26 connected in sequence. The lower rotating plate 26 is rotatably connected within the rotating groove 23. The first steel wire rope 13 and the second steel wire rope 14 are wound around the middle disc 25. The upper rotating plate 24 completely covers the rotating groove 23. Since the rotating groove 23 is completely covered by the upper rotating plate 24, the turntable 3 and the hand pad 1 appear as a single unit with no clearly visible gap between them.

[0031] In one implementation, such as Figure 2 As shown.

[0032] The micro switch provided in this embodiment has its rope groove 15 connected to the rotating groove 23.

[0033] In this embodiment, in order to allow the first wire rope 13 and the second wire rope 14 to be led out from the rotating groove 23, the rope groove 15 for accommodating the first wire rope 13 and the second wire rope 14 is connected to the rotating groove 23.

[0034] In one implementation, such as Figure 3 As shown.

[0035] The micro switch provided in this embodiment has one end of its reset spring 16 fixed to the opening of the rope groove 15 facing the first mirror clamp 4 or the second mirror clamp 5, and the other end of the reset spring 16 fixed to the outside of the first wire rope 13 or the second wire rope 14. When the turntable 3 is rotated in different directions, the ball 11 on the first wire rope 13 or the ball 11 on the second wire rope 14 can be extended. When the turntable 3 is released, the ball 11 on the first wire rope 13 and the ball 11 on the second wire rope 14 are reset under the action of the reset springs 16 on both sides.

[0036] In this embodiment, to better demonstrate the return spring 16, Figure 3 Dissecting the hand pad 1, in this embodiment, the function of the return spring 16 is to reset the ball 11 on the first wire rope 13 and the ball 11 on the second wire rope 14. During operation, the first wire rope 13 and the second wire rope 14 move in the same direction. To ensure that the first wire rope 13 and the second wire rope 14 have the same restoring force, the return springs 16 on both sides are of the same specification.

[0037] In one implementation, such as Figure 4 As shown.

[0038] The micro switch provided in this embodiment has two elastic hinge shafts 8.

[0039] In this embodiment, the opening of the first mirror clip 4 and the second mirror clip 5 is controlled by setting two elastic hinge shafts 8.

[0040] In one implementation, such as Figure 4 As shown.

[0041] The micro switch provided in this embodiment has an I-shaped disc reel 18 with a hollow center that is screwed into a lifting column 22 passing through its center. When the first lens clamp 4 is opened, the first pull cable 19 pulls the reel 18 to rotate, causing the lifting column 22 to rise. When the second lens clamp 5 is opened, the second pull cable 20 pulls the reel 18 to rotate, causing the lifting column 22 to rise. Pressing the lifting column 22 to return it to its original position allows the first lens clamp 4 to close via the first pull cable 19 or the second lens clamp 5 to close via the second pull cable 20. Furthermore, both the first pull cable 19 and the second pull cable 20 are flexible wires. The rotating cavity 17 accommodates the unwound first pull cable 19 or second pull cable 20.

[0042] In this embodiment, during the opening of the first lens clip 4 or the second lens clip 5, the reel 18 can be rotated by the first pull cable 19 or the second pull cable 20. This reel 18 is located within the rotating cavity 17 and is screwed into the lifting column 22. That is, the rotation of the reel 18 can be converted into the raising of the lifting column 22. Similarly, pressing the lifting column 22 back to its original position can drive the rotation of the reel 18, thereby causing the first lens clip 4 or the second lens clip 5 to close by pulling the first pull cable 19 or the second pull cable 20.

[0043] The specific embodiments described above further illustrate the inventive purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above descriptions are merely specific embodiments of the present invention and are not intended to limit the scope of protection of the present invention. In particular, it should be noted that any modifications, equivalent substitutions, or improvements made by those skilled in the art within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
