Description

Technical Field

[0001] This utility model relates to the field of electrical switch technology, specifically to a rocker switch for a high-power vacuum cleaner. Background Technology

[0002] A rocker switch is an electronic component that uses mechanical rocking to open and close a circuit. It is widely used in household appliances, industrial equipment, and electronic circuits. Its core structure consists of a plastic housing, a metal rocker plate, contacts, terminals, and an operating button. When the button is pressed down, one end of the rocker plate contacts the terminal, forming a circuit; when released, the contacts separate, and the circuit is broken. Rocker switches achieve switching states through physical rocking, requiring minimal operating force and offering fast response, making them suitable for scenarios requiring frequent on / off switching.

[0003] The rocker switch on a vacuum cleaner controls its start / stop operation. Since high-powered vacuum cleaners inevitably encounter dusty environments, the rocker switch on a high-powered vacuum cleaner should have a certain degree of dust protection to prevent particles, dust, and other impurities from entering the switch and affecting its normal electrical performance. Currently, the rocker switches on existing high-powered vacuum cleaners lack a reasonable dust-proof structure, resulting in poor dust protection, or the dust-proof components are complex, making assembly difficult and inefficient.

[0004] In view of this, there is an urgent need to design a rocker switch with a reasonable dustproof structure so that it can be adapted to high-power vacuum cleaners. Summary of the Invention

[0005] To address the aforementioned problems, this utility model provides a rocker switch for a high-power vacuum cleaner, comprising a base, a housing, and a rocker button. The housing is connected to the base, and a linkage inner cavity is provided between the base and the housing. At least one set of conductive components is disposed within the linkage inner cavity, and a dustproof linkage component is also included. The dustproof linkage component is connected to the rocker button via a snap-fit ​​structure. A transmission outer cavity is formed on the housing, and a partition plate is provided between the linkage inner cavity and the transmission outer cavity. The partition plate includes a boss portion protruding from the partition plate, and inclined platform portions are provided on both sides of the boss portion. At least one linkage insertion hole is formed on the boss portion. A hinge hole is formed on the surface of the housing opposite to the boss portion. Hinge posts are provided on both sides of the dustproof linkage component, and the hinge posts are connected to the hinge holes. A linkage post is provided on the dustproof linkage component opposite to the boss portion, and the linkage post is located between the two hinge posts. The linkage post passes through the linkage insertion hole, and a pressure component that is linked to the conductive components is disposed within the linkage post.

[0006] The present invention is further configured such that both sides of the dustproof linkage extend toward one side of the partition plate to form a rotating part, the hinge column is located on the outer side of the rotating part, and the side of the hinge column near the base forms a hinge guide slope.

[0007] The present invention is further provided with a mounting groove between the boss portion and the inner wall of the outer shell, and the rotating portion is located in the mounting groove.

[0008] The present invention is further configured such that each of the dustproof linkage components is provided with a snap-fit ​​groove at the position corresponding to the inclined platform, the inner wall of the snap-fit ​​groove is provided with a snap-fit ​​step, the inner side of the rocker button is provided with a snap-fit ​​insert plate, the side of the snap-fit ​​insert plate is provided with a snap-fit ​​protrusion, the snap-fit ​​insert plate is connected in the snap-fit ​​groove and the snap-fit ​​protrusion and the snap-fit ​​step form a snap-fit ​​engagement.

[0009] The present invention is further configured such that the side of the snap-fit ​​step near the rocker button is a snap-fit ​​guide slope, and the side of the snap-fit ​​step near the outer shell is a snap-fit ​​locking end face.

[0010] The present invention is further provided with a travel limiting part at the position of the dustproof linkage corresponding to the inclined platform, and the travel limiting part protrudes towards the transmission outer cavity; when the rocker switch is in the on or off state, one of the travel limiting parts abuts against the inclined platform.

[0011] The present invention is further configured such that the conductive component includes a first conductive pin, a second conductive pin, and a conductive contact piece. The first conductive pin and the second conductive pin are both fixed on the base, and the conductive contact piece is oscillatingly connected to the first conductive pin. Both the second conductive pin and the conductive contact piece are provided with contacts. The pressure assembly drives the conductive contact piece to oscillate by toggling the rocker button, so as to realize the contact and separation between the contact of the conductive contact piece and the contact of the second conductive pin.

[0012] The present invention is further configured such that the inside of the linkage column is a pressure-top cavity, the pressure-top assembly includes a pressure-top spring and a toggle block, the conductive contact includes an arc-shaped recess, one end of the pressure-top spring abuts against the dustproof linkage component, the other end of the pressure-top spring abuts against the toggle block, and the toggle block abuts against the arc-shaped recess.

[0015] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

A pressure component is set on the linkage column to cooperate with the conductive component. When the rocker button drives the dustproof linkage component to rotate around the hinged column, the rocker switch is turned on and off.

[0017] This utility model rocker switch forms the first physical barrier by engaging a dustproof linkage with the rocker button, preventing dust from entering the interior through the button's gaps. Furthermore, the partition plate between the linkage inner cavity and the transmission outer cavity has a boss and a ramp, forming a barrier-like sealing structure. The boss blocks large dust particles, while the ramp guides dust to both sides, reducing direct intrusion paths. This dustproof structure does not sacrifice operational flexibility. When the rocker button is pressed down, the linkage column drives the conductive component to switch on and off via the pressure assembly, ensuring rapid response (short response time) while preventing dust from being brought into the interior during operation, thus improving the reliability of the rocker switch.

[0018] Traditional dustproof accessories (such as sealing rings and dust covers) require additional fixing steps, while the dustproof linkage component of this utility model rocker switch is directly connected to the rocker button through a snap-fit ​​structure. The hinge posts on both sides of the dustproof linkage component cooperate with the hinge holes of the outer shell to achieve quick positioning, integrating the dustproof function into the internal structure of the switch. At the same time, it reduces the number of accessories, reduces assembly complexity, improves production consistency, and enables rocker switches to be mass-produced and automated.

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.

[0032] Combined with appendix Figure 1 To be continued Figure 12This utility model provides a rocker switch for a high-power vacuum cleaner, comprising a base 1, a housing 2, and a rocker button 3. The housing 2 is connected to the base 1, and a linkage inner cavity 4 is provided between the base 1 and the housing 2. At least one set of conductive components 5 is disposed within the linkage inner cavity 4. The rocker switch also includes a dustproof linkage component 6, which is connected to the rocker button 3 via a snap-fit ​​structure. A transmission outer cavity 7 is provided on the housing 2, and a partition plate 21 is provided between the linkage inner cavity 4 and the transmission outer cavity 7. The partition plate 21 includes a boss portion 22 protruding from the partition plate. The boss portion 22 has inclined platform portions 23 on both sides. The boss portion 22 has at least one linkage insertion hole 24. The outer shell 2 has a hinge hole 25 on the surface opposite to the boss portion 22. The dustproof linkage component 6 has hinge posts 61 on both sides. The hinge posts 61 are connected in the hinge holes 25. The dustproof linkage component 6 has a linkage post 62 on the position opposite to the boss portion 22. The linkage post 62 is located between the two hinge posts 61. The linkage post 62 passes through the linkage insertion hole 24. The linkage post 62 has a pressure assembly 8 that is linked and connected to the conductive component 5.

[0033] In this embodiment, the number of conductive components 5, the number of linkage sockets 24, and the number of pressure components 8 are the same. The design is flexible according to the control circuit required by the rocker switch. This embodiment is illustrated by setting two sets of conductive components 5.

[0034] In this technical solution, the dustproof linkage 6 of the rocker switch is rotatably connected to the transmission outer cavity 7 of the housing 2 via the hinge post 61, and passes through the linkage insertion hole 24 of the boss part 22 via the linkage post 62. A pressure assembly 8 is provided on the linkage post 62 to cooperate with the conductive assembly 5. When the rocker button 3 drives the dustproof linkage 6 to rotate around the hinge post 61, the rocker switch is turned on and off.

[0035] In this embodiment, the dustproof barrier formed by the outer transmission cavity 7 sunken on the outer shell 2 and the protrusion 22 and inclined plate 23 on the partition plate 21 can effectively reduce the entry of large particulate impurities into the inner cavity 4.

[0036] In this embodiment, after the rocker button 3 and the dustproof linkage 6 are engaged, pressing the rocker button 3 can cause the dustproof linkage 6 to rotate on the outer shell 2 with the hinge column 61 as the rotation center.

[0037] In this embodiment, the dustproof linkage 6 extends from both sides toward one side of the partition plate 21 to form a rotating part 63. The hinge post 61 is located on the outer side of the rotating part 63. The hinge post 61 forms a hinge guide slope 611 on the side near the base 1. The hinge guide slope 611 facilitates the assembly of the dustproof linkage 6 onto the outer shell 2.

[0038] In this embodiment, a mounting groove 26 is provided between the boss portion 22 and the inner wall of the outer shell 2, and the rotating portion 63 is located in the mounting groove 26. The mounting groove provides clearance for the installation of the dustproof linkage 6 on the outer shell 2.

[0039] In this embodiment, as shown in the appendix Figure 7 To be continued Figure 10 As shown, the dustproof linkage 6 is provided with a snap-fit ​​groove 64 at the position corresponding to the inclined platform 23. The inner wall of the snap-fit ​​groove 64 is provided with a snap-fit ​​step 65. The inner side of the rocker button 3 is provided with a snap-fit ​​insert plate 31.

The snap-fit ​​insert plate 31 is connected in the snap-fit ​​groove 64 and the snap-fit ​​protrusion 32 and the snap-fit ​​step 65 form a snap-fit ​​engagement.

[0040] In this embodiment, as shown in the appendix Figure 10 As shown, the side of the snap-fit ​​step 65 near the rocker button 3 is a snap-fit ​​guide slope 651, and the side of the snap-fit ​​step 65 near the outer shell 1 is a snap-fit ​​locking end face 652. When the snap-fit ​​insert 31 is fully inserted into the snap-fit ​​groove 64, the snap-fit ​​protrusion 32 and the snap-fit ​​locking end face 652 form a relatively stable locking engagement. The snap-fit ​​guide slope 651 is used to ensure the smooth connection of the rocker button 3 into the dustproof linkage 6.

[0041] In this embodiment, as shown in the appendix Figure 8 As shown, the dustproof linkage 6 is also provided with a travel limit part 66 at the position corresponding to the inclined platform 23. The travel limit part 66 protrudes towards the transmission outer cavity 7. When the rocker switch is in the on or off state, one of the travel limit parts 66 abuts against the inclined platform 23, so that the cooperation between the pressure assembly 8 and the conductive assembly 5 is within a reasonable travel range.

[0042] In this embodiment, as shown in the appendix Figure 6As shown, the conductive component 5 includes a first conductive pin 51, a second conductive pin 52, and a conductive contact 53. The first conductive pin 51 and the second conductive pin 52 are both fixed on the base 1. The conductive contact 53 is oscillatingly connected to the first conductive pin 51. The second conductive pin 52 is provided with a pin contact 521, and the conductive contact 53 is provided with a contact piece contact 531. The pressure assembly 8 drives the conductive contact 53 to oscillate by the rocker button 3, so as to realize the contact and separation between the contact piece contact 531 of the conductive contact 53 and the pin contact 521 of the second conductive pin 52.

[0043] In this embodiment, the linkage column 62 has a pressure cavity 621 inside, the pressure assembly 8 includes a pressure spring 81 and a toggle block 82, the conductive contact 53 includes an arc-shaped recess 532, one end of the pressure spring 81 abuts against the dustproof linkage 6, the other end of the pressure spring 81 abuts against the toggle block 82, and the toggle block 82 abuts against the arc-shaped recess 532.

[0044] In this embodiment, when the conductive components 5 are configured in two or more groups, the base 1 and / or the outer shell 2 are provided with a partition on the side near the linkage cavity; as shown in the attached figure. Figure 11 and attached Figure 12 As shown, the base 1 has a base partition 11 in the middle and the outer shell 2 has an outer shell partition 27 in the middle. The base partition 11 and the outer shell partition 27 are both located between the conductive components 5.

[0045] In this embodiment, as shown in the appendix Figure 5 and attached Figure 6 As shown, the base 1 has a positioning protrusion 12 on its outer periphery, and the outer shell 2 has a positioning opening 28 on its surface. The outer shell 2 is connected to the base 1 through the positioning opening 28 and the positioning protrusion 12.

[0046] This utility model rocker switch forms the first physical barrier by engaging the dustproof linkage 6 with the rocker button 3, preventing dust from entering the interior through the button gap. Furthermore, the partition plate 21 between the linkage inner cavity 4 and the transmission outer cavity 7 is provided with a boss 22 and a ramp 23, forming a barrier-like sealing structure. The boss 22 blocks large dust particles, while the ramp 23 guides the dust to both sides, reducing the direct intrusion path. This dustproof structure does not sacrifice operational flexibility. When the rocker button 3 is pressed down, the linkage column 62 drives the conductive component 5 to switch on and off through the pressure assembly 8, ensuring a fast response (short response time) and preventing dust from being brought into the interior during operation, thus improving the reliability of the rocker switch.

[0047] Traditional dustproof accessories (such as sealing rings and dust covers) require additional fixing steps, while the dustproof linkage component 6 of this utility model rocker switch is directly connected to the rocker button 3 through a snap-fit ​​structure. The hinge posts 61 on both sides of the dustproof linkage component 6 cooperate with the hinge holes 25 of the outer shell 2 to achieve quick positioning, integrate the dustproof function into the internal structure of the switch, reduce the number of accessories, reduce assembly complexity, improve production consistency, and enable rocker switches to be mass-produced and automated.
