Description

Technical Field

[0001] This invention belongs to the field of water control machine technology, and specifically relates to a waterproof structure for the motherboard compartment of an integrated water control machine. Background Technology

[0002] The water control unit mainly consists of three parts: an electronic control module, an IC card, and a signal transmitter. The electronic control module is the core of the water control unit. It is responsible for controlling the sampling, billing, and display units of the water control unit. It also takes timely measures to process the operating status of the water control unit and saves important operating data for future use and analysis. Currently, most water control units are integrated, allowing the water supply pipe to run directly through the unit's interior for flow measurement and water supply switch control.

[0003] Then, when the water supply pipe passes through the water control machine, the solenoid valve and flow meter need to be powered to operate and need to be electrically connected to the PCB board inside the water control machine. However, the location where the water supply pipe is prone to leakage is precisely where the solenoid valve and flow meter are installed. When leakage occurs, water can easily enter the water control machine, damaging all its internal electronic components and affecting its service life.

[0004] Therefore, it is necessary to invent a waterproof structure for the motherboard compartment of an integrated water control machine to solve the above problems. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a waterproof structure for the motherboard compartment of an integrated water control machine, thereby resolving the issues raised in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a waterproof structure for the mainboard compartment of an integrated water control machine, comprising a water control machine housing, a cover provided at the bottom of the water control machine housing, a partition provided inside the water control machine housing, water supply pipes passing through the two sides of the water control machine housing between the cover and the partition, and at least one water-proof device provided on the surface of one end of the water supply pipe located inside the water control machine housing.

[0007] The water-proof device includes a water-proof cover, with multiple wire holes on the top of the water-proof cover and the surface of the partition plate. A wire spool is placed between the wire holes on the water-proof cover and the surface of the partition plate. Several first O-rings are evenly arranged on the inner wall of the wire spool. Sealing plugs are movably fitted on the surface of the wire spool at the top and bottom of the isolation cover and the bottom of the partition plate. A second O-ring is placed between the sealing plug and the wire spool. A clamping cap is fitted on the top end of the wire spool on the partition plate. The clamping cap is threadedly connected to the wire hole on the surface of the partition plate.

[0008] Furthermore, the isolation cover includes two support bases fixedly connected to the inner wall of the cover. The top of the two support blocks is provided with a retaining cover, and semi-circular grooves are opened on the surface of the support base and both ends of the retaining cover. The semi-circular grooves of the support base and the retaining cover match the outer diameter of the water supply pipe. A sealing ring is provided between the support base and the retaining cover. Sealing plates are provided on both sides of the retaining cover. The bottom and sides of the sealing plates are respectively sealed to the cover and the inner wall of the support base by sealing gaskets. The sealing plates and the retaining cover are integrally formed.

[0009] Furthermore, the sealing plug is frustum-shaped, made of rubber material, and one end extends into the wire hole. A connecting rod is fixedly connected to the top of the sealing plug located at the bottom of the partition. The top of the connecting rod is connected to the same sealing ring plate, which is located inside the wire hole of the partition and in contact with the compression cap.

[0010] Furthermore, force-bearing rods are movably inserted into both sides of the card cover. The force-bearing rods extend through the top of the card cover to the outside, and a third O-ring is provided at the position where the force-bearing rods penetrate the card cover. A first push plate is provided at the bottom of the sealing plug inside the card cover, a second push plate is provided at the top of the sealing plug at the top of the card cover, and a third push plate is provided at the bottom of the sealing plug at the bottom of the partition. Both ends of the first push plate and the third push plate are connected to the force-bearing rods by fixing rods.

[0011] Furthermore, a reset spring is provided between the top of the first push plate and the cover, and grooves matching the fixing rod are opened on the inner walls of both sides of the cover. A water-permeable hole is opened on the surface of the section of the bobbin located between the second push plate and the third push plate.

[0012] Furthermore, a U-shaped power cylinder is provided between the third push plate and the partition plate. T-shaped pistons are provided inside both ends of the U-shaped power cylinder. One end of one of the T-shaped pistons is fixedly connected to the third push plate, and the other end of the T-shaped piston moves through the third push plate and is fixedly connected to the second push plate. The interior of the U-shaped power cylinder, located between the two T-shaped pistons, is filled with liquid.

[0013] Furthermore, the spring force of the return spring is greater than the frictional force between the force-bearing rod and the retaining cover.

[0014] The technical effects and advantages of this invention are as follows:

[0015] 1. This invention effectively seals off areas of the water supply pipe prone to leakage by setting up a water-sealing device, creating an independent space and increasing the waterproof effect of the water control machine. Even if the sealed space leaks, the partition still provides waterproofing, greatly enhancing the waterproof function of the water control machine and extending its service life.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] This invention provides a waterproof structure for the motherboard compartment of an integrated water control machine, such as... Figure 1-4 As shown, the device includes a water control housing 1, a cover 2 at the bottom of the housing 1, a partition 3 inside the housing 1, and water supply pipes 4 extending through the housing 1 between the cover 2 and the partition 3 on both sides. At least one water-proof device 5 is provided on the surface of one end of the water supply pipe 4 inside the housing 1. The water-proof device 5 includes a water-proof cover 501, with multiple wire holes 502 on the top of the water-proof cover 501 and the surface of the partition 3. A wire spool 503 is provided between the wire holes 502 on the water-proof cover 501 and the partition 3. A plurality of first O-rings 504 are evenly distributed on the inner wall of the wire spool 503. Sealing plugs 505 are movably fitted onto the surface of the wire spool 503 at the top and bottom of the cover and the bottom of the partition 3, and a first O-ring 504 is provided between the sealing plug 505 and the wire spool 503. Two O-rings 506, the wire drum 503 has a compression cap 507 fitted on one end surface of the top of the partition 3, the compression cap 507 is threaded to the wire hole 502 on the surface of the partition 3. When the device is in use, the cables of the solenoid valve and the flow meter are passed through the wire drum 503, so that the cables enter the PCB on the top of the partition 3 inside the water control machine housing 1 and are connected. The compression cap 507 is then tightened. Then the cover 2 is installed on the water control machine housing 1, so that the support seat 508 on the surface of the cover 2 contacts the retaining cover 509, and the sealing plate 512 seals the inner wall of the cover 2, thereby forming a closed space between the support seat 508 and the retaining cover 509, which increases the waterproof effect of the water control machine. Even if the closed space leaks, the partition 3 will still provide waterproofing, which greatly increases the waterproof function of the water control machine and increases its service life.

[0026] like Figure 2-5As shown, the isolation cover includes two support bases 508 fixedly connected to the inner wall of the cover 2. A retainer 509 is provided on the top of each support base. Semicircular grooves 510 are formed on the surface of the support bases 508 and at both ends of the retainers 509. The semicircular grooves 510 of the support bases 508 and retainers 509 are matched to the outer diameter of the water supply pipe 4. A sealing ring 511 is provided between the support bases 508 and retainers 509. Sealing plates 512 are provided on both sides of the retainers 509. The bottom and sides of the sealing plates 512 are sealed to the cover 2 and the inner wall of the support bases 508 using sealing gaskets. The sealing plates 512 and retainers 509 are integrally formed. The sealing plug 505 is frustoconical in shape. 05 is made of rubber material, with one end extending into the wire hole 502. A connecting rod 513 is fixedly connected to the top of the sealing plug 505 located at the bottom of the partition 3. The top of the connecting rod 513 is connected to the same sealing ring plate 514, which is located inside the wire hole 502 of the partition 3 and contacts the compression cap 507. Force rods 515 are movably inserted into both sides of the retaining cover 509. The force rods 515 extend through the top of the retaining cover 509 to the outside, and a third O-ring 516 is provided at the point where the force rod 515 passes through the retaining cover 509. A first push plate 517 is provided at the bottom of the sealing plug 505 inside the retaining cover 509, and a first push plate 517 is provided at the top of the sealing plug 505 at the top of the retaining cover 509. A second push plate 518 is provided, and a third push plate 519 is provided at the bottom of the sealing plug 505 at the bottom of the partition 3. Both ends of the first push plate 517 and the third push plate 519 are connected to the force-bearing rod 515 by fixing rods. The cover 2 is installed with the water control machine housing 1, so that the support seat 508 on the surface of the cover 2 contacts the cover 509, and the sealing plate 512 seals the inner wall of the cover 2, thereby forming a closed space between the support seat 508 and the cover 509. The sealing ring 511 seals the contact position between the support seat 508 and the cover 509. When the support seat 508 contacts the cover 509, it exerts a compressive force on the force-bearing rod 515 protruding from the bottom of the cover 509, causing the force-bearing rod 515 to retract into the cover 509. Furthermore, the force-bearing rod 515, under the action of the fixed rod, drives the first push rod and the third push plate 519 to move, causing the first push plate 517 and the second push plate 518 to push the corresponding sealing plug 505 into the wire hole 502, thereby sealing the wire drum 503 and the wire drum 503, creating a separate sealed space for the position of the solenoid valve and the flow meter, and preventing water from leaking into the water control machine housing 1 through the space between the wire drum 503 and the wire hole 502. When the third push plate 519 pushes the sealing plug 505 to move, the sealing plug 505 at the bottom of the partition 3 pushes the connecting rod 513 and the sealing ring plate 514, so that they contact the pressure cap 507, thereby preventing liquid leaking to the outside of the cover 509 from entering the space at the top of the partition 3.

[0027] like Figure 4 As shown, a return spring 520 is provided between the top of the first push plate 517 and the cover 509. The inner walls on both sides of the cover 509 are provided with grooves that match the fixing rod. A section of the surface of the spool 503 located between the second push plate 518 and the third push plate 519 is provided with a water-permeable hole 521. By providing the water-permeable hole 521, even if the liquid inside the enclosed space leaks through the inside of the spool 503, it can enter the space at the bottom of the partition 3 through the water-permeable hole 521.

[0028] like Figure 3 and Figure 4 As shown, a U-shaped power cylinder 522 is provided between the third push plate 519 and the partition plate 3. T-shaped pistons 523 are provided inside both ends of the U-shaped power cylinder 522. One end of one T-shaped piston 523 is fixedly connected to the third push plate 519, and the other end of the T-shaped piston 523 moves through the third push plate 519 and is fixedly connected to the second push plate 518. The U-shaped power cylinder 522 is filled with liquid between the two T-shaped pistons 523. The elastic force of the return spring 520 is greater than the frictional force between the force rod 515 and the retainer 509. When the third push plate 519 moves, it pushes the T-shaped piston 523 connected to it, causing the T-shaped piston 523 at the other end of the U-shaped power cylinder 522 to push the second push plate 518, thereby applying pressure to the sealing plug 505 at the bottom of the second push plate 518, thereby further sealing the spool 503 and the wire hole 502.

[0029] Working principle of this invention:

[0030] Refer to the instruction manual appendix Figure 1-5When the device is in use, the cables of the solenoid valve and flow meter are passed through the cable reel 503, allowing the cables to connect to the PCB at the top of the internal partition 3 of the water control unit housing 1. The clamping cap 507 is then tightened. The cover 2 is then installed onto the water control unit housing 1, with the support 508 on the surface of the cover 2 contacting the retaining cover 509, and the sealing plate 512 sealing the inner wall of the cover 2. This creates a closed space between the support 508 and the retaining cover 509. The sealing ring 511 further secures the support 508 and the retaining cover 509 together. The 09 contact position is sealed, and when the support 508 contacts the cover 509, it exerts a compressive force on the force-bearing rod 515 protruding from the bottom of the cover 509, causing the force-bearing rod 515 to retract into the cover 509. Furthermore, under the action of the fixed rod, the force-bearing rod 515 drives the first push rod and the third push plate 519 to move, causing the first push plate 517 and the second push plate 518 to push the corresponding sealing plug 505 into the wire hole 502, thereby sealing the space between the wire spool 503 and the wire spool 503, allowing the solenoid valve and flow... The position of the meter creates a separate sealed space, and to prevent leakage, water flows through the space between the reel 503 and the wire hole 502 into the water control housing 1. When the third push plate 519 pushes the sealing plug 505 to move, the sealing plug 505 at the bottom of the partition 3 pushes the connecting rod 513 and the sealing ring plate 514, making them contact the pressure cap 507, thereby preventing liquid leaking to the outside of the cover 509 from entering the space at the top of the partition 3. When the third push plate 519 moves, it pushes the T-shaped piston 52 connected to it. 3. The T-shaped piston 523 at the other end of the U-shaped power cylinder 522 pushes the second push plate 518, thereby applying pressure to the sealing plug 505 at the bottom of the second push plate 518, further sealing the gap between the wire drum 503 and the wire hole 502. This effectively seals the area of ​​the water supply pipe 4 that is prone to leakage, creating an independent space and increasing the waterproof effect of the water control machine. Even if the sealed space leaks, the partition plate 3 still provides waterproofing, greatly increasing the waterproof function of the water control machine and extending its service life.
