Description

Technical Field

[0001] This utility model relates to the field of rotary switch technology, and in particular to a pseudo three-position rotary switch. Background Technology

[0002] A fan switch is a switch used to control the rotation and speed of a fan. There are many types of fan switches. For example, push-button switches and rotary switches are more common. Nowadays, rotary switches are generally divided into fan speed control switches and oscillation switches. Currently, fan speed control rotary switches and oscillation switches are basically two independent switches and cannot be combined into a single rotary switch.

[0003] To address the aforementioned shortcomings, an existing Chinese patent publication (CN220774197U) describes a rotary switch for a circulating fan. While it integrates speed control and oscillation functions by using high-conductivity and low-conductivity contacts to interact with different speed settings and the live wire connection, allowing for directional speed adjustment and oscillation adjustment through cyclic rotation, the rotary switch's operation relies on a motor and switching circuit. The principle of the rotary switch involves controlling the motor's operation with current, guiding the current to the motor's coils to generate a magnetic field, causing the rotor to rotate. The rotary switch controls the current flow and its magnitude (different speed settings correspond to different current levels, i.e., different motor speeds), thus enabling the fan's on / off, speed adjustment, and oscillation functions. However, existing rotary switches for circulating fans have three gears, requiring three different current levels to control the motor. When shifting between gears, there is a power outage between the adjacent gears, followed by immediate power restoration after shifting to the desired gear. This increases power loss, and the frequent increases and decreases in current can affect the motor's lifespan. Utility Model Content

[0004] The purpose of this utility model is to provide a pseudo-three-position rotary switch, which is formed by setting a first-position switch piece and a second-position switch piece, and the second-position switch piece is integrally formed with two connection positions with the same current, thus forming a pseudo-three-position and true two-position switch piece. This can reduce the power loss during position adjustment, thereby effectively extending the service life of the motor. The rotary operation is simple and convenient, and at the same time, it can also realize position adjustment and / or oscillation adjustment.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a pseudo three-position rotary switch, comprising a base plate and an upper shell, wherein an elastic rotating assembly is connected inside the upper shell, the elastic rotating assembly includes a rotating shaft, and a conductive sheet is connected to the lower end of the rotating shaft. One end of the conductive sheet is provided with a low-conductivity contact head, and the other end is provided with a high-conductivity contact head. A live wire connecting piece, a first-position switch piece, a second-position switch piece, and a toggle switch piece are sequentially distributed along the circumferential direction between the base plate and the upper shell. The second-position switch piece is provided with two connection positions. The low-conductivity contact head contacts the first-position switch piece or the second-position switch piece as the conductive sheet rotates, and the high-conductivity contact head contacts any one of the live wire connecting piece, the first-position switch piece, and the second-position switch piece as the conductive sheet rotates.

[0011] More preferably, the outer edge of the base plate is provided with locking teeth that engage with the locking hole, and the middle part of the base plate is provided with a shaft hole to facilitate the lower end of the rotating shaft to be connected.

[0012] The beneficial effects of this utility model are as follows: It includes a base plate and an upper shell. An elastic rotating assembly is connected inside the upper shell. The elastic rotating assembly includes a rotating shaft. A conductive sheet is connected to the lower end of the rotating shaft. One end of the conductive sheet is provided with a low-conductivity contact head, and the other end is provided with a high-conductivity contact head. A live wire connecting piece, a first-position switch piece, a second-position switch piece, and a toggle switch piece are distributed sequentially along the circumferential direction between the base plate and the upper shell. The second-position switch piece is provided with two connection positions. The low-conductivity contact head contacts the first-position switch piece or the second-position switch piece as the conductive sheet rotates. The high-conductivity contact head contacts any one of the live wire connecting piece, the first-position switch piece, and the second-position switch piece as the conductive sheet rotates. By setting a first-position switch piece and a second-position switch piece, and the second-position switch piece being integrally formed with two connection positions of the same current, a switch piece with a pseudo-three-position and true two-position configuration is formed. In this way, the power loss during gear adjustment can be reduced when rotating in conjunction with the rotating shaft, thereby effectively extending the service life of the motor. The rotation operation is simple and convenient. At the same time, it can also realize gear adjustment and / or toggle adjustment. Attached Figure Description

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0018] like Figure 1-3As shown, a pseudo three-position rotary switch includes a base plate 1 and an upper shell 2. An elastic rotating assembly is connected inside the upper shell 2. The elastic rotating assembly includes a rotating shaft 31 piece 3. A conductive plate 4 is connected to the lower end of the rotating shaft 31 piece 3. One end of the conductive plate 4 is provided with a low-conductivity contact 5, and the other end is provided with a high-conductivity contact 6. A live wire connecting piece 7, a first-position switch piece 8, a second-position switch piece 9, and a toggle switch piece 10 are sequentially distributed along the circumference between the base plate 1 and the upper shell 2. The second-position switch piece 9 has two connection positions. The low-conductivity contact 5 contacts the first-position switch piece 8 or the second-position switch piece 9 as the conductive plate 4 rotates. The high-conductivity contact 6... The rotation of the conductive piece 4 makes contact with any one of the live wire connecting piece 10, the first-position switch piece 8, and the second-position switch piece 9. By setting the first-position switch piece 8 and the second-position switch piece 9, and the second-position switch piece 9 being integrally formed with two connection positions with the same current, when the high-conductivity contact head 6 of the rotating part rotates to the two connection positions of the second-position switch, the current is the same, so the speed of the motor and the fan blade is also the same. Therefore, it forms a pseudo-three-position, true two-position switch adjustment structure with the first-position switch piece 8. In this way, the rotation with the rotating shaft 31 piece 3 can reduce the power loss during gear adjustment, thereby effectively extending the service life of the motor. The rotation operation is simple and convenient. At the same time, it can also realize gear adjustment and / or oscillation adjustment.

[0019] In this embodiment, the two-position switch piece 9 includes a long position piece 91 and a short position piece 92. The long position piece 91 extends out of the outer edge of the base plate 1. The long position piece 91 and the short position piece 92 are an integral structure. Compared with the separate arrangement of the two-position switch piece 9 and the three-position switch piece in the prior art, this embodiment processes them into an integral structure and removes the protruding connecting section at the outer end of the three-position switch piece. Thus, the integral structure of the two-position switch piece 9 leaves only one terminal. When the high-conductivity contact head 6 rotates with the conductive piece 4, it first rotates to the first-position switch piece 8, then rotates to the position of the long position piece 91 of the second-position switch piece 9 to make the motor reach the second-position speed, and then continues to rotate to the position of the short position piece 92 of the second-position switch piece 9 to keep the motor at the second-position speed.

[0020] like Figure 4 As shown, when the high conductivity contact 6 rotates with the conductive plate 4, it first rotates to the first position switch plate 8, then rotates to the short position plate 92 of the second position switch plate 9 to make the motor reach the second speed, and then continues to rotate to the long position plate 91 of the second position switch plate 9 to make the motor continue to maintain the second speed.

[0021] In this embodiment, the inner ends of the live wire connecting piece 10, the first-position switch piece 8, and the second-position switch piece 9 are all provided with plug-in pieces 11. The base plate 1 is provided with corresponding plug-in holes 12 to facilitate the connection and fixation of the plug-in pieces 11, so as to facilitate the fixed connection of the live wire connecting piece 10, the first-position switch piece 8, and the second-position switch piece 9 with the base plate 1.

[0022] In this embodiment, the oscillating switch piece 10 includes a straight piece 101 connected to the conductive piece 4. An inclined piece 102 is integrally formed at the outer end of the straight piece 101. Since the oscillating switch piece 10 is directly opposite the connecting ear 24, this embodiment sets the oscillating switch piece 10 as an integrally bent structure to facilitate the wiring processing of the oscillating switch piece 10.

[0023] In this embodiment, the rotating shaft 31 includes a rotating shaft 31, and a rotating body 32 is provided at the lower end of the rotating shaft 31. A through hole 33 is provided in the rotating body 32, and a spring 34 is provided in the connecting hole. A ball bearing 35 is provided at one end of the through hole 33, and a bolt is provided at the other end. When the rotating shaft 31 and the rotating body 32 rotate, the cooperation of the spring 34 and the ball bearing 35 facilitates elastic rotation and positioning.

[0024] In this embodiment, the upper shell 2 includes an octagonal shell 21. The lower end of the shell 21 is provided with a shell plate 22. The shell plate 22 is provided with a snap-fit ​​hole 23. The two ends of the shell 21 are symmetrically provided with connecting ears 24. The connecting ears 24 are provided with connecting holes. The outer edge of the bottom plate 1 is provided with snap teeth 13 that engage with the snap-fit ​​hole 23. The middle part of the bottom plate 1 is provided with a shaft hole 14 to facilitate the shaft connection of the lower end of the rotating shaft 31. The upper shell 2 and the bottom plate 1 are fixedly connected by the snap-fit ​​hole 23, and the shaft hole 14 provides support for the axial rotation of the rotating shaft 31.

[0025] Based on the concept of this utility model, there may be changes in the specific implementation methods and application scope. The content of this specification should not be construed as a limitation of this utility model.
