Description

Technical Field

[0001] This utility model generally relates to the field of bathroom equipment technology, and more specifically, to a circuit board sealing structure, a drain button, and a bathroom device. Background Technology

[0002] Most bathroom products operate in humid environments, with some components housed in concealed water tanks. These tanks are relatively enclosed and poorly ventilated, resulting in high humidity levels. To prevent rust, corrosion, and damage to electrical components, potting compound is commonly used for sealing. However, some electrical components have unique characteristics. For example, potting compound can cover LED chips on circuit boards, affecting the lighting effect. Or, in appliances with moving parts, potting compound can bind the moving parts, preventing them from moving. While these circuit boards are sealed by the casing, the wires connecting to the outside can still introduce humid air into the casing. Therefore, a sealing solution that provides a more comprehensive seal without compromising the functionality of the components is needed to meet these requirements.

[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0016] According to one embodiment of the present invention, a sealing member is included, which is installed at the junction of the connecting portion and the circuit portion to isolate the first cavity and the second cavity;

[0017] The seal is provided with a socket for connecting the circuit board.

[0018] According to one embodiment of the present invention, the sealing member is provided with flexible edges, which are located on both sides facing the surface of the circuit board.

[0046] like Figures 1-3 As shown, this embodiment provides a circuit board sealing structure, including: a main body 100, which has a first cavity 110 and a second cavity 120; a circuit board 200, which includes a circuit part 210 and a connecting part 220, the circuit part 210 being located within the first cavity 110 and the connecting part 220 being located within the second cavity 120; a conductor 300, one end of which extends into the second cavity 120 and connects to the connecting part 220; wherein, the second cavity 120 is provided with a sealing material for isolating the second cavity 120 from the outside of the main body 100. It is understood that the conductor 300 can be a wire, a metal sheet, etc. Besides using a filler with good sealing effect, the sealing material can also be other components with sealing functions, such as a partition, a pre-fabricated sealing plug, etc. This embodiment utilizes a specially designed multi-chamber main structure with a first cavity 110 and a second cavity 120 to perform partitioned sealing of the circuit board. Local sealing is achieved by applying adhesive at specific points where the circuit board connects to the wires, preventing the exchange of internal and external gases and avoiding the entry of moisture. This prevents electrical components from rusting, corroding, and being damaged, ensuring the normal operation of the circuit board and extending its service life.

[0047] In this embodiment, as Figures 1-3 As shown, the main body 100 includes a housing 101 and a sealing cover 600 that is sealed to the housing 101. The housing 101 and the sealing cover 600 are sealed to form a first cavity 110 and a second cavity 120. The sealant is a gel. The second cavity 120 has an opening 121. The gel is filled into the second cavity 120 through the opening 121 to isolate the second cavity 120 from the outside of the housing 101. Specifically, the housing 101 is designed as a generally convex frame structure. Therefore, the circuit board 200 and the sealing cover 600 are designed as generally convex structures. The housing 101 includes a shell 111 and a base plate 112. The sealing cover 600 is provided on the opposite side of the base plate 112. The sealing cover 600 is sealed to the shell 111 to form the first cavity 110 and the second cavity 120.

[0048] Specifically, the housing 111, the base plate 112, and the sealing cover 600 enclose and form a first cavity 110 and a second cavity 120. At this time, the circuit part 210 of the circuit board 200 is placed in the first cavity 110, the connecting part 220 of the circuit board 200 is placed in the second cavity 120, one end of the conductor 300 extends into the opening 121 of the second cavity 120 and connects with the connecting part 220, and then the colloid is filled into the second cavity 120 to seal the opening 121, thereby isolating and sealing the second cavity 120 from the outside of the housing 101.

[0049] In this embodiment, as Figure 2 As shown, the connecting part 220 divides the second cavity 120 into a first filling area 123 and a second filling area 124. The first filling area 123 is provided with an opening 121, and the first filling area 123 and the second filling area 124 are provided with a connecting gap 125. The gap between the connecting part 220 and the inner wall of the outer shell 101 forms the connecting gap 125. Filling the first filling area 123 and the second filling area 124 with filler material isolates the first filling area 123 and the second filling area 124 from the outside of the outer shell 101.

[0050] In other embodiments, the communication gap 125 can be closed, and filler can be directly filled into the first filling area 123 to isolate the opening 121 of the first filling area 123 from the outside of the outer casing 101.

[0051] In this embodiment, as Figures 2-4 As shown, the sealing structure of the circuit board 200 includes a sealing element 500. The sealing element 500 has a socket 510 for connecting the circuit board 200 and a flexible edge 520. The socket 510 is fitted at the junction of the connecting part 220 and the circuit part 210, and the flexible edge 520 is tightly fitted to the inner wall of the main body 100 to isolate the first cavity 110 and the second cavity 120, so that the first cavity 110 forms a sealed cavity. It can be understood that the sealing element 500 isolates the first cavity 110 and the second cavity 120 and forms a preset potting space. The potting is restricted to a local part of the circuit board 200, such as the connecting part 220, and will not cover the entire circuit board 200, nor will it leak to components that cannot be potted, such as the circuit part 210. In this embodiment, the size of the connecting part 220 is much smaller than that of the circuit part 210. During assembly, the connecting part 220 is passed through the socket 510 of the sealing member 500, so that the sealing member 500 is fitted onto the circuit board 200 and placed inside the housing 101. Then, the sealing cover 600 is closed and fixed onto the housing 111. Here, the conductor 300 can extend from the opening 121 into the second cavity 120 to connect to the connecting part 220, or the conductor 300 can be directly connected to the connecting part 220 first and then extend out of the housing 101 from the opening 121.

[0052] In other embodiments, the outer shell 101 and the sealing cover 600 are integrally formed. After the circuit board 200 and the sealing element 500 are installed inside the outer shell 101, the bottom plate 112 is then covered and fixed onto the outer shell 101.

[0053] Specifically, such as Figures 2-4 As shown, the flexible edges 520 of the sealing element 500 are located on both sides facing the surface of the circuit board 200 and are tightly fitted with the inner walls of the base plate 112 and the sealing cover 600 to form a sealed first cavity 110. It can be understood that in this embodiment, the cross-section of the flexible edge 520 is approximately "[, <, {" etc. After installation, the base plate 112 and the sealing cover 600 exert a certain clamping force on the flexible edge 520, causing the flexible edge 520 to deform and open to both sides, which can better fit the inner walls of the base plate 112 and the sealing cover 600, resulting in better sealing. At the same time, due to the local deformation of the flexible edge 520, the clamping force is greatly released, making the force on the main body of the sealing element 500 very small. Thus, the force transmitted to the circuit board 200 will be very small, which can avoid the adverse consequences of excessive local force on the circuit board 200.

[0054] In some embodiments, the circuit section 210 is provided with a light-emitting component, and the sealing cover 600 is a light guide plate that has a light-guiding function. The light guide plate is used to adjust the light emitted by the light-emitting component to be more uniform and softer. For example, at the light-transmitting part of the drain button, the light is uniformly refracted to the light-transmitting part of the button through the light guide plate, so that the light emitted from the light-transmitting part of the button is more uniform and softer.

[0055] In some embodiments, the circuit unit 210 is provided with a sensing component for sensing information about objects and the human body. The sensing component can sense signals through the sealing cover 600; the sensing component is an infrared sensor, a microwave sensor, or a laser sensor. It is understood that the circuit unit 210 can interact with the outside world through the sensing component, thereby achieving intelligent control. The sealing cover 600 can be a transparent structure to facilitate the operation of the infrared sensor. In other embodiments, a transparent window for the infrared sensor to operate can also be provided in the sealing cover 600.

[0056] In some embodiments, the circuit section 210 is provided with an adjustable electrical component, which can be adjusted via the sealing cover 600; the adjustable electrical component is an adjustable resistor, an adjustable potentiometer, or an adjustable switch.

[0057] According to another aspect disclosed in this utility model, such as Figure 5As shown, this embodiment provides a drainage button, including a button frame 700 and a main body 100. The main body 100 is provided with a circuit board sealing structure as described above. The main body 100 is movably hinged to the button frame 700 or fixed to the button frame 700. It can be understood that the main body 100 of the circuit board sealing structure of this application can be directly used as a button. In this embodiment, there are two main bodies 100, which control the large and small flushes of water. The main body 100 is provided with a hinge part 102. When the main body 100 is movably hinged to the button frame 700, pressing the main body 100 causes it to rotate. At this time, as the main body 100 rotates, different button functions are realized; or, the infrared sensor or other sensor on the main body 100 senses changes in the signal and sends feedback information to realize different button functions.

[0058] In other embodiments, the main body 100 is directly fixed to the button frame 700, which can also realize the control of the button.

[0059] According to another aspect of the present invention, a bathroom fixture is provided, including the above-mentioned drain button, which is used to control the bathroom fixture to drain water.

[0060] It should be understood that the various examples described above can be utilized in multiple directions (e.g., tilted, inverted, horizontal, vertical, etc.) and in multiple configurations without departing from the principles of this invention. The embodiments shown in the accompanying drawings are merely examples of effective application of the principles of this invention, and the invention is not limited to any specific details of these embodiments.
