Description

Technical Field

[0001] This utility model relates to the field of rocker switch technology, specifically to a reliable rocker switch and a vacuum cleaner. Background Technology

[0002] A rocker switch is an electronic component that controls the on / off state of a circuit through mechanical displacement. Its core structure consists of a spring rod and two sets of contact points. When the user pushes or presses the switch, the spring rod deforms, causing the contact points to close (conduct current) or open (cut off current), thereby controlling the start and stop of the equipment.

[0003] Existing rocker switches for vacuum cleaners have the following defects: The rocker switch is connected to the vacuum cleaner handle switch slot via elastic elements on both sides. The rocker switch is electrically connected to the circuit board through the handle switch slot via its bottom pin. Currently, the snap-fit ​​structure between the rocker switch base and the cover results in gaps at the snap-fit ​​joint. During use, dust and impurities may accumulate in the handle switch slot of some vacuum cleaners, causing them to enter the rocker switch through the gaps at the snap-fit ​​joint, affecting the normal switching on and off of the rocker switch. During use, users may accidentally touch the rocker switch while holding the vacuum cleaner handle, causing the operation to be interrupted. In addition, the current rocker switch has defects such as poor tactile feedback when toggling and the movement and stationary contacts inside the switch not making proper contact after prolonged use.

[0004] In view of this, there is an urgent need to design a reliable rocker switch and vacuum cleaner to solve the technical defects of existing vacuum cleaner rocker switches. Utility Model Content

[0006] In a first aspect, this utility model provides a rocker switch with reliable on / off switching, comprising a base, a housing connected to the base, a stationary contact connected to the base, a movable contact linked to the stationary contact, a rocker button movably connected to the housing, and a pressing assembly connected to the rocker button. The pressing assembly is linked to the movable contact. The base includes a base portion and a support portion located at the center of the base portion. A pressing step is provided on the outer periphery of the base portion, and an annular sealing gasket is connected to the pressing step. The side of the support portion... The cover is provided with a positioning buckle and a positioning hole. The end face of the cover away from the rocker button is provided with a pressing edge. The positioning buckle is connected in the positioning hole. The pressing edge abuts against the annular sealing gasket. The moving contact includes a driving part. Both ends of the driving part are respectively connected to a linkage part. The center of the driving part is provided with a blocking part protruding towards the pressing assembly. The blocking part is provided with a positioning groove on the side near the linkage part. The pressing assembly is linked to the blocking part and the positioning groove as the rocker button is turned on and off.

[0007] In one possible implementation, the stationary contact piece includes a first stationary contact piece and a second stationary contact piece. The first stationary contact piece includes a first insert portion and a folded portion, with a stationary contact point on the folded portion. The second stationary contact piece includes a second insert portion and support portions located on both sides of the second insert portion. The driving portion is connected to the support portion. The linkage portion includes a first linkage portion and a second linkage portion. The first linkage portion has a moving contact point, and the base has a limiting portion. When the pressing assembly acts on the positioning groove near the first stationary contact piece, the moving contact point of the first linkage portion abuts against the stationary contact point. When the pressing assembly acts on the positioning groove away from the first stationary contact piece, the second linkage portion abuts against the limiting portion.

[0008] In one possible implementation, the positioning groove has a limiting contact surface on the side away from the blocking part, and a guide contact surface on the side of the positioning groove closer to the base.

[0009] In one possible implementation, the moving contact and the two positioning slots are both located on the central axis of the moving contact piece.

[0010] In one possible implementation, the pressure assembly includes a spring and a pressure member, the rocker button includes a toggle post, one end of the toggle post has a toggle opening, the two ends of the spring respectively abut against the rocker button and the pressure member, the pressure member extends out of the toggle opening and abuts against the movable contact piece, and the pressure member moves along the central axis with the rocker button.

[0011] In one possible implementation, the top of the cover is provided with a raised dustproof boss, and the two sides of the dustproof boss are provided with hinge seats. The rocker button is provided with a hinge part, which is connected to the hinge seat. The toggle post is inserted through the dustproof boss.

[0012] In one possible implementation, the driving part has support wings on both sides, and the support part has a support slot in the position opposite to the support wings. The support slot has a V-shaped contact surface that protrudes toward the support wings.

[0013] In one possible implementation, the first pin portion and the second pin portion are arranged parallel to each other, and positioning barbs are provided on both sides of the first pin portion and both sides of the second pin portion.

[0014] In one possible implementation, the positioning buckle includes a positioning end face and a guide end face, the positioning end face facing the annular sealing gasket and the guide end face facing the rocker button.

[0015] In a second aspect, a vacuum cleaner is provided, including the aforementioned reliable rocker switch.

[0016] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0017] (1) When the user presses the rocker button, the pressure component will push the drive unit. The pressure component needs to pass the top of the blocking part to slide into the positioning groove. When passing the blocking part, a significant resistance peak will be generated. Once it slides into the positioning groove, the resistance drops sharply and stabilizes, giving the user clear operation feedback, indicating that the switch has been stably switched to the position. This structure provides a clearer and more comfortable operation stroke and feedback. The improved button design makes the user need a clearer and more purposeful pressing action to trigger the switch, which significantly reduces the risk of accidental touch caused by the hand of the vacuum cleaner handle being accidentally touched by the tiger's mouth or fingers, resulting in work interruption.

[0018] (2) The positioning groove of the moving contact on the rocker switch provides a stable locking point for the pressure assembly. When the pressure assembly falls into the positioning groove, the moving contact and the stationary contact are kept in stable and reliable pressure contact under the action of the pressure assembly, which effectively solves the problem of incomplete contact or poor connection.

[0019] (3) When the cover and base of the rocker switch are snapped together, the pressing edge of the cover is pressed tightly against the annular sealing gasket on the base, forming a continuous sealing barrier at the junction of the base and the cover. This effectively prevents dust and impurities in the vacuum cleaner handle switch groove from entering the switch, preventing these impurities from affecting the electrical connection of the moving and stationary contacts or hindering the movement of the rocker button, thus ensuring the long-term reliability of the switch.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] Example 1

[0032] Combined with appendix Figure 1 To be continued Figure 10This utility model provides a reliable rocker switch, comprising a base 1, a housing 2 connected to the base 1, a stationary contact piece connected to the base 1, a movable contact piece 5 linked to the stationary contact piece, a rocker button 6 movably connected to the housing 2, and a pressing assembly 7 connected to the rocker button 6. The pressing assembly 7 is linked to the movable contact piece 5. The base 1 includes a base portion 11 and a support portion 12 located at the center of the base portion 11. The outer periphery of the base portion 12 is provided with a pressing step 13, and an annular sealing gasket 8 is connected to the pressing step 13. The side of the support portion 12 is provided with a positioning... The cover 2 has a positioning hole 21 and a pressing edge 22 on the end face of the cover 2 away from the rocker button 6. The positioning buckle is connected in the positioning hole and the pressing edge 22 abuts against the annular sealing gasket 8. The moving contact piece 5 includes a driving part 51 and a linkage part is connected to both ends of the driving part 51. The center of the driving part 51 has a blocking part 54 that protrudes towards the pressing assembly 7. The blocking part 54 has a positioning groove 55 on the side near the linkage part. The pressing assembly 7 is linked to the positioning groove 55 through the blocking part 54 and the positioning groove 55 when the rocker button 6 is turned on and off.

[0033] In this embodiment, when the user presses the rocker button, the pressing component 7 pushes the driving part 51. The pressing component 7 needs to pass the apex of the blocking part 51 to slide into the positioning groove 55. When passing the blocking part 54, a significant resistance peak is generated. Once it slides into the positioning groove 55, the resistance drops sharply and stabilizes, giving the user clear operational feedback that the switch has been stably switched to the correct position. This structure provides a clearer and more comfortable operating stroke and feedback. The improved button design requires the user to perform a more specific and purposeful pressing action to trigger the switch, significantly reducing the risk of accidental touches caused by the hand grip or fingers when holding the vacuum cleaner handle, which may interrupt the operation.

[0034] In this embodiment, as shown in the appendix Figure 8 To be continued Figure 10As shown, the stationary contact piece includes a first stationary contact piece 3 and a second stationary contact piece 4. The first stationary contact piece 3 includes a first insert portion 31 and a folding portion 32. The folding portion 32 is provided with a stationary contact point 33. The second stationary contact piece 4 includes a second insert portion 41 and a support portion 42 located on both sides of the second insert portion 41. The driving portion 51 is connected to the support portion 42. The linkage portion includes a first linkage portion 52 and a second linkage portion 53. The first linkage portion 52 is provided with a moving contact point 56. The base 1 is provided with a limiting portion 15. When the pressing assembly 7 acts on the positioning groove 55 near the first stationary contact piece 3, the moving contact point 56 of the first linkage portion 52 abuts against the stationary contact point 33. When the pressing assembly 7 acts on the positioning groove 55 away from the first stationary contact piece 3, the second linkage portion 53 abuts against the limiting portion 15.

[0035] In this embodiment, as shown in the appendix Figure 9 As shown, the positioning groove 55 has a limiting contact surface 551 on the side away from the blocking part 54, and a guide contact surface 552 on the side of the positioning groove 55 closer to the base 1. The limiting contact surface 551 ensures that the pressing assembly 7 can stably abut against the positioning groove 55. The guide contact surface 552 and the arc surface of the driving part 51 provide guidance for the second half of the rocker switch switching. The positioning groove 55 of the moving contact on the rocker switch provides a stable locking point for the pressing assembly 7. When the pressing assembly 7 falls into the positioning groove 55, the pressing assembly ensures stable and reliable pressure contact between the moving contact and the stationary contact, effectively solving the problem of incomplete contact or loose connection.

[0036] In this embodiment, as shown in the appendix Figure 9 As shown, the moving contact 56 and the two positioning grooves 55 are both located on the central axis of the moving contact piece 5.

[0037] In this embodiment, when the rocker switch 6 is operated to turn on or off, the rocker switch 6 drives the pressure assembly 7 to move along the central axis of the moving contact piece 5, and must pass through the blocking part 54; when the rocker switch is in the on or off state, the pressure assembly 7 abuts against the positioning groove 55.

[0038] In this embodiment, as shown in the appendix Figure 2 To be continued Figure 3 As shown, the pressure assembly 7 includes a spring 71 and a pressure member 72. The rocker button 6 includes a toggle post 61. One end of the toggle post 61 has a toggle opening 62. The two ends of the spring 71 abut against the rocker button 6 and the pressure member 72, respectively. The pressure member 72 extends out of the toggle opening 62 and abuts against the movable contact piece 5. The pressure member 72 moves along the central axis with the rocker button 6.

[0039] In this embodiment, as shown in the appendix Figure 5 To be continued Figure 7 As shown, the top of the cover 2 is provided with a raised dustproof boss 23, and the two sides of the dustproof boss 23 are provided with hinge seats 24. The rocker button 6 is provided with a hinge part 63, which is connected to the hinge seat 24. The toggle post 61 is inserted through the dustproof boss 23.

[0040] In this embodiment, the dustproof protrusion 23 can effectively prevent external impurities from entering the interior of the housing.

[0041] In this embodiment, as shown in the appendix Figure 9 To be continued Figure 10 As shown, the drive unit 51 has support wings 57 on both sides, and the support unit 42 has a support slot 43 opposite to the support wings 57. The support slot 43 has a V-shaped contact surface 44 protruding towards the support wings 57 inside. The cooperation between the support wings 57 and the V-shaped contact surface 44 ensures the accuracy of the movement of the moving contact piece 5.

[0042] In this embodiment, as shown in the appendix Figure 1 and attached Figure 8 As shown, the first pin portion 31 and the second pin portion 41 are arranged in parallel. The first pin portion 31 is provided with a first positioning barb 34 on both sides, and the second pin portion 41 is provided with a second positioning barb 45 on both sides.

[0043] In this embodiment, as shown in the appendix Figure 4 To be continued Figure 5 As shown, the positioning buckle 14 includes a positioning end face 141 and a guide end face 142. The positioning end face 141 faces the annular sealing gasket 8, and the guide end face 142 faces the rocker button 6. The above structure can realize the quick assembly of the cover 2 and the base 1, and when the cover 2 is snapped onto the base 1, the annular sealing gasket 8 is tightly pressed.

[0044] In this embodiment, when the cover 2 and the base 1 of the rocker switch are snapped together, the pressing edge of the cover 2 directly and tightly presses against the annular sealing gasket 8 on the base 1, forming a continuous sealing barrier at the junction of the base 1 and the cover 2. This effectively prevents dust and impurities in the vacuum cleaner handle switch groove from entering the switch, preventing these impurities from affecting the electrical connection between the moving and stationary contacts or hindering the movement of the rocker button 6, thereby ensuring the long-term reliability of the switch's on / off state.
