Detailed Implementation
[0034] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.
[0035] Please see Figure 1-8 As shown, a button and indicator light structure is assembled in a housing 100, including: a button 201 and an indicator light 202 disposed on a PCB board 200, the PCB board 200 being assembled in the housing 100; the housing 100 is provided with a button hole 101 corresponding to the button 201 and a lamp hole 102 corresponding to the indicator light 202, and also includes: a button sealing gasket 300.
[0036] The button sealing gasket 300 has a first surface 301 and a second surface 302, with the first surface 301 and the second surface 302 facing away from each other.
[0037] The button sealing gasket 300 forms a button chamber 310 and an indicator light chamber 320, with the indicator light chamber 320 penetrating the first surface 301 and the second surface 302.
[0038] The button sealing gasket 300 is pressed between the PCB board 200 and the inner wall of the housing 100. The button 201 is located in the button chamber 310, and the indicator light 202 is located in the indicator light chamber 320. A light guide column 120 is installed in the lamp hole 102. The light guide column 120 is connected to the first surface 301 of the button sealing gasket 300 and covers the first end opening 321 of the indicator light chamber 320.
[0039] In this technology, the button 201 and indicator light 202 are disposed on the upper surface of the PCB board 200. The button sealing gasket 300 is pressed between the PCB board 200 and the inner wall of the housing 100. The second surface 302 of the button sealing gasket 300 is flat and is pressed against the upper surface of the PCB board 200. The first surface 301 of the button sealing gasket 300 is pressed either entirely or partially against the inner wall of the housing 100. The button 201 is located in the button chamber 310, and the indicator light 202 is located in the indicator light chamber 320. This effectively seals and prevents light leakage. At the same time, external dust and water are blocked by the button sealing gasket 300 and cannot enter the button chamber 310 and the indicator light chamber 320, thus providing dustproof and waterproof functions.
[0040] The outer casing 100 can be the casing of a household appliance, such as the casing of a vacuum cleaner.
[0041] Alternatively, the housing 100 can also be the housing of other household appliances, such as the housing of a floor scrubber, the housing of a handheld mite remover, etc.
[0042] The button sealing gasket 300 is integrally molded from a soft rubber material, such as silicone, allowing it to tightly connect with the PCB board 200 and the inner wall of the outer casing 100, thus achieving a seal. The button chamber 310 extends from the second surface 302 toward the first surface 301, penetrating the second surface 302 but not the first surface 301. The button chamber 310 can be rectangular, cylindrical, etc. Figure 7-8 As shown, the button chamber 310 is cylindrical;
[0043] The indicator light chamber 320 extends from the second surface 302 toward the first surface 301, and the indicator light chamber 320 penetrates both the first surface 301 and the second surface 302. The indicator light chamber 320 can be prismatic, columnar, etc. Figure 7-8 As shown, the indicator light chamber 320 is rectangular; the indicator light chamber 320 has a first end opening 321 on the first surface 301 and a second end opening 322 on the second surface 302.
[0044] Both the button hole 101 and the lamp hole 102 penetrate the outer and inner walls of the housing 100. The shapes of the button hole 101 and the lamp hole 102 can be modified according to requirements. The light guide column 120 mainly serves to guide light. The light guide column 120 is connected to the first surface 301 of the button sealing gasket 300 and covers the first end opening 321 of the indicator light chamber 320. When the indicator light 202 emits light, the light is transmitted to the light guide column 120, and the light guide column 120 emits light.
[0045] In one embodiment, the button sealing gasket 300 is provided with a pin 350; the PCB board 200 is provided with a socket 210; the button sealing gasket 300 is mounted on the PCB board 200, and the pin 350 is inserted into the socket 210.
[0046] In this technology, the button sealing gasket 300 is quickly assembled into the PCB board 200 by the cooperation of the pin 350 and the socket 210, and then installed into the housing 100 along with the PCB board 200, making the assembly quick and convenient.
[0047] like Figure 7 The pins 350 are provided in four sets, and the pins 350 are formed on the second surface 302 and extend away from the first surface 301; two sets of pins 350 are provided for the button chamber 310 and two sets of pins 350 are provided for the indicator light chamber 320.
[0048] The number of sockets 210 on the PCB board 200 matches the number of pins 350. There are four sockets 210, which enables the button sealing gasket 300 to be stably installed on the PCB board 200.
[0049] Optionally, the number of sockets 210 and pins 350 can be adapted.
[0050] Alternatively, the PCB board 200 can be modified to have a pin and the button sealing gasket 300 can be provided with a hole, which can also make the button sealing gasket 300 stably installed on the PCB board 200.
[0051] In one implementation, such as Figure 4-8 As shown, the first surface 301 is provided with a first inclined surface 3011, and the first end opening 321 of the indicator light chamber 320 is located on the first inclined surface 3011; the light guide column 120 is connected to the first inclined surface 3011, and the light guide column 120 is provided with a second inclined surface 121, and the first inclined surface 3011 and the second inclined surface 121 abut against each other.
[0052] In this technology, the first inclined surface 3011 and the second inclined surface 121 can play the role of guiding installation and positioning, pressing the light guide column 120 and positioning it in the lamp hole 102.
[0053] like Figure 8 In terms of orientation, the first inclined plane 3011 slopes downwards from left to right;
[0054] like Figure 3 Regarding the orientation, the first inclined surface 3011 tilts to the right from bottom to top; during installation, first install the button sealing gasket 300 onto the PCB board 200, then insert the PCB board 200 together with the button sealing gasket 300 upwards into the housing 100, as shown. Figure 1 As shown, during the insertion process, the first inclined surface 3011 and the second inclined surface 121 cooperate. As the button sealing gasket 300 is assembled, the first inclined surface 3011 and the second inclined surface 121 will be pressed tighter and tighter, achieving a tight connection, while making the light guide post 120 less likely to loosen.
[0055] like Figure 1-3 As shown, the cross-section of the light guide column 120 is T-shaped. The light guide column 120 is installed in the lamp hole 102 from inside the housing 100. Due to the T-shaped design of the light guide column 120, the light guide column 120 will not protrude out of the lamp hole 102. The light guide column 120 is pressed into the lamp hole 102 by the button sealing gasket 300.
[0056] Optionally, such as Figure 3 As shown, the PCB board 200 is mounted on a component 400, which may be a motor or a motor housing. The component 400 is mounted in the housing 100 and positioned so that the PCB board 200 is positioned in the housing 100.
[0057] Alternatively, the housing 100 can be a split structure, and the PCB board 200 can be fixed in the housing 100 with screws.
[0058] In one implementation, such as Figure 1 and Figure 8 As shown, the inner wall of the outer shell 100 is provided with a third inclined surface 103, and the first inclined surface 3011 and the third inclined surface 103 abut against each other.
[0059] In this technology, a rib 130 is provided on the inner wall of the outer casing 100 around the lamp hole 102. The end of the rib 130 facing the PCB board 200 forms the third inclined surface 103. The light guide post 120 is installed after the lamp hole 102, positioned within the area surrounding the rib 130, and does not protrude beyond the rib 130. Figure 2 In terms of orientation, the light guide column 120 does not protrude to the right of the third inclined surface 103 of the rib 130, thereby preventing light from diffusing inside the housing 100 and preventing light crosstalk.
[0060] The second inclined surface 121 and the third inclined surface 103 simultaneously abut against the first inclined surface 3011, so that the button sealing gasket 300 is pressed tightly against the inner wall of the PCB board 200 and the outer shell 100, and fits tightly.
[0061] In one embodiment, the button chamber 310 is opened from the second surface 302 toward the first surface 301 but does not penetrate the first surface 301; the first surface 301 is provided with a sealing ring cartilage 330, the sealing ring cartilage 330 protrudes away from the second surface 302, and the sealing ring cartilage 330 is pressed against the inner wall of the outer shell 100.
[0062] Furthermore, the projection of the button chamber 310 onto the first surface 301 falls within the surrounding area of the sealing ring cartilage 330.
[0063] In this technology, a sealing ring cartilage 330 is provided on the first surface 301. The sealing ring cartilage 330 can fit tightly against the inner wall of the outer shell 100, and the sealing ring cartilage 330 is arranged around the key hole 101. In accordance with the shape of the key cavity 310, the sealing ring cartilage 330 is arranged in a ring.
[0064] In addition, the presence of the sealing ring cartilage 330 reduces the contact area between the first surface 301 and the inner wall of the outer casing 100, preventing excessive friction between the button sealing gasket 300 and the inner wall of the outer casing 100 during the installation of the PCB board 200 and the outer casing 100, which could lead to installation difficulties.
[0065] In one embodiment, a button cover 110 is installed on the button hole 101; an elastic trigger part 340 is provided on the first surface 301 of the button sealing gasket 300; the button cover 110 corresponds to the elastic trigger part 340, and the button 201 is triggered by the elastic trigger part 340.
[0066] like Figure 8 As shown, the first surface 301 is thin-shaped corresponding to the position of the button chamber 310, and a spring-loaded trigger part 340 is provided in the middle of the thin-shaped position. Under external force, the spring-loaded trigger part 340 can move up and down, as shown. Figure 1 As shown, button 201 corresponds to and is close to elastic trigger part 340.
[0067] When in use, pressing the button cover 110 pushes the elastic trigger part 340 as follows. Figure 1 As shown, moving to the right triggers button 201; releasing the force applied to button cover 110 causes the elastic trigger part 340 to move to the left and reset.
[0068] In one implementation, such as Figure 3 As shown, the button cover 110 is snap-fitted onto the button hole 101; the light guide post 120 is snap-fitted onto the lamp hole 102;
[0069] During assembly, the light guide post 120 can be pre-attached to the lamp hole 102 with double-sided adhesive for pre-positioning, and then pressed into the lamp hole 102 by the button sealing gasket 300.
[0070] like Figure 3 As shown, the button cover 110 is installed in the button hole 101. While limiting the movement, it can have a certain travel. The user can press the button cover 110 to push the elastic trigger part 340 and then trigger the button 201.
[0071] The button and indicator light structure of this utility model has a simple and quick installation method, such as... Figure 1 As shown, the sealing ring cartilage 330 is pressed tightly against the inner wall of the outer shell 100, and the first inclined surface 3011 is pressed against the second inclined surface 121 and the third inclined surface 103 of the light guide post 120, which plays a good sealing role, waterproof and dustproof. If applied in a vacuum cleaner, the outer shell 100 is the vacuum cleaner shell. After the button sealing gasket 300 is installed, it can prevent air leakage from the button hole 101 and the lamp hole 102, which plays a good sealing role. The button 201 is located in the button chamber 310, and the indicator light is located in the indicator light chamber 320, which effectively prevents light leakage.

Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
[0073] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
