Description

Technical Field

[0001] The utility model relates to the technical field of water purification, in particular to a waterway plate structure and drinking water equipment. Background Art

[0002] A common design trend in the water purifier market is the inclusion of a high-pressure switching system equipped with a one-way check valve. This system's core function is to accurately and automatically terminate the purifier's operation when the water level in the water storage container (i.e., a water tank or pressure drum) reaches its upper limit. This prevents water from being wasted due to overflow while ensuring the stability and long-term effectiveness of the purifier's operation. Furthermore, the inclusion of a one-way check valve further enhances the system's protective capabilities, effectively preventing water from flowing back from the pressure vessel into the water system, thereby avoiding the risk of filter contamination.

[0003] However, current water purifiers have also exposed certain limitations in their use of high-pressure switch technology. Specifically, to improve product compatibility and market adaptability, the high-pressure switch components with integrated one-way check valves used in most water purifiers are standardized, independently produced components, and come with a pipe structure for connecting the filter outlet to the water storage container. While this design facilitates the installation and replacement of the entire component, it inevitably leads to an increase in the number of bends in the water system, which in turn exacerbates pressure loss during water flow, affecting water purification efficiency and water quality. In addition, the one-way check valve is a consumable part, and each damaged replacement requires the entire high-pressure switch assembly to be disassembled and replaced, increasing the complexity and cost of maintenance.

[0027] Embodiment one:

[0028] refer to Figure 1 、 Figure 2 A waterway plate structure includes a waterway plate main body 1, a water supply flow path 2 is formed in the waterway plate main body 1, and a water outlet cavity 3 is provided at the end of the flow path in the direction of fluid conveyance of the water supply flow path 2. A water outlet pipe 4 and a pressure measuring connection port 5 are provided on the waterway plate main body 1. The pressure measuring connection port 5 is connected to the water outlet cavity 3 and is detachably connected to a high-pressure switch module 6. The high-pressure switch module 6 is connected to the water outlet cavity 3 through the pressure measuring connection port 5 for sensing the pressure change in the water outlet cavity 3. The water outlet pipe 4 is used to connect to an external waterway for water supply. A one-way valve 7 is provided inside the water outlet pipe 4. The flow direction of the one-way valve 7 is the same as the water outlet direction of the water outlet pipe 4.

[0029] Compared with the technical solution of "the existing water purifier adopts a high-pressure switch component that integrates a one-way check valve and independently provides a water pipe", the above technical solution sets a water outlet chamber 3 and a pressure measuring connection port 5 on the water supply flow path 2 integrated in the waterway plate main body 1, and connects the high-pressure switch module 6 to the water outlet chamber 3 through the pressure measuring connection port 5, so that the high-pressure switch does not bear the task of fluid circulation, and the one-way valve 7 originally integrated in the high-pressure switch is detachably built into the water outlet pipe 4, thereby improving the integration of the waterway, which is beneficial to reducing the bending nodes in the waterway and reducing the pressure loss when the heavy water flows through. Moreover, since the one-way valve 7 is independently arranged relative to the high-pressure switch, when the one-way valve 7 is damaged, the one-way valve 7 can be disassembled and replaced separately, which can reduce the maintenance difficulty and use cost.

[0030] Specifically, the water outlet pipe 4 has an output port 41 for outputting fluid, and the inner wall of the output port 41 extends radially to form an annular stop surface 42. When the one-way valve 7 is placed in the output port 41, the annular stop surface 42 can provide axial abutment for the one-way valve 7 to be positioned. In addition, a snap-fit ​​structure is connected to the opening of the output port 41, and the snap-fit ​​structure is used for the external water pipe to be plugged and fixed. The end of the one-way valve 7 away from the annular stop surface 42 has a positioning surface 71 for axial abutment of the external water pipe. During installation, the one-way valve 7 can be bidirectionally abutted by the annular stop surface 42 and the external water pipe to install and position the one-way valve 7. This helps to simplify the installation process of the one-way valve 7 and the external water pipe, and can achieve a quick and stable connection without using additional structures and fasteners, and makes it more convenient when the one-way valve 7 needs to be replaced or repaired.

[0031] To enhance the seal between the one-way valve 7 and the inner wall of the output port 41, in this embodiment, the outer wall of the one-way valve 7 is recessed inward to form a mounting groove 72. A sealing ring 73 is disposed within the mounting groove 72 for elastically abutting the inner wall of the output port 41. When the one-way valve 7 is installed in the output port 41, the sealing ring 73 is squeezed by the inner wall of the output port 41 and elastically deforms. This deformation allows the sealing ring 73 to fit tightly against the inner wall of the output port 41, thereby preventing fluid from leaking through the gap between the one-way valve 7 and the output port 41. Furthermore, the sealing ring 73 can pre-position the one-way valve 7 when the external water pipe is not connected to the waterway plate, preventing the one-way valve 7 from becoming detached from the output port 41 during transportation. The sealing ring 73 can be made of an elastic material such as rubber, silicone, or polyurethane.

[0032] In this embodiment, an annular groove 43 is formed on the inner wall of the output port 41. The engaging structure includes a cap 44 that elastically engages with the annular groove 43. The cap 44 is for inserting an external water pipe, and the inner wall of the cap 44 is engaged with a claw 45 for fixing the water pipe. During operation, the external water pipe is inserted into the output port 41 through the cap 44. The inner wall of the cap 44 is provided with a claw 45. The claw 45 can elastically engage with the outer wall of the external water pipe to ensure a stable connection between the water pipe and the output port 41. Since the engaging structure composed of the claw 45 can be removed from the annular groove 43 of the output port 41, the output port 41 provides a larger disassembly space when replacing and removing the one-way valve 7, making replacement and maintenance more convenient.

[0033] The waterway plate body 1 comprises at least two integrally injection-molded plastic panels, each of which has several grooves. These panels are sealed together to form the waterway plate body 1. The grooves of these panels cooperate to form the water supply path 2 and the water outlet cavity 3. This integrally injection-molded and sealed connection of the plastic panels creates a complete waterway structure. This design not only simplifies the manufacturing process and improves precision, but also facilitates maintenance and customization. The plastic panels can be sealed together using methods such as sealant, O-rings, heat fusion, or ultrasonic welding.

[0034] In addition to the aforementioned detachable snap-fit ​​structure, this embodiment also provides another technical solution for facilitating the removal and replacement of the one-way valve 7. Specifically, the output port 41 is formed, from the outside to the inside, with a first pipe section 46 and a second pipe section 47 that is detachably connected to the first pipe section 46. An annular retaining surface 42 is formed on the inner wall of the first pipe section 46, and the snap-fit ​​structure is connected to the opening of the second pipe section 47. By dividing the output port 41 into the first pipe section 46 and the detachable second pipe section 47, and providing the annular retaining surface 42 and the snap-fit ​​structure on the first pipe section 46 and the second pipe section 47, respectively, during disassembly, only the second pipe section 47 needs to be removed, allowing for direct and easy access and replacement of the one-way valve 7.

[0035] Specifically, the second pipe segment 47 can be removably connected to the first pipe segment 46 in various embodiments. In this embodiment, the second pipe segment 47 is removably and sealedly connected to the first pipe segment 46 via a threaded connection. The first and second pipe segments 46, 47 are each provided with matching threads, which can be connected by rotating them together. The threaded connection not only provides a mechanical connection but also achieves a sealing effect through the tight fit between the threads. In actual applications, to further enhance the sealing performance, the threaded connection can be coated with sealant or sealed with an O-ring or other sealing element.

[0036] In this embodiment, the high-voltage switch module 6 includes a base 61 and a top cover 62. The top cover 62 is connected to one end of the base 61 and cooperates with the base 61 to form a pressure measuring chamber 63. A connecting pipe 64 is provided at the end of the base 61 away from the top cover 62, communicating with the pressure measuring chamber 63. A trigger assembly 65 is disposed within the pressure measuring chamber 63. The top cover 62 is provided with a conductive assembly 66 that cooperates with the trigger assembly 65 to switch on and off. During operation, the connecting pipe 64 connects to the pressure measuring connector 5, connecting the pressure measuring chamber 63 to the water outlet chamber 3. The trigger assembly 65 within the pressure measuring chamber 63 senses pressure changes within the pressure measuring chamber 63. As water flows in and out of the water outlet chamber 3, the pressure within the water outlet chamber 3 changes, which is then transmitted to the pressure measuring chamber 63 through the connecting pipe 64. When the pressure within the pressure measuring chamber 63 reaches a preset value, the trigger assembly 65 deforms or displaces, causing it to come into contact with or separate from the conductive assembly 66, thereby controlling the on / off of the external circuit and, in turn, the waterway.

[0037] The trigger assembly 65 can be a metal diaphragm or spring structure. For example, when the pressure in the pressure measuring chamber 63 changes, the metal diaphragm deforms. This deformation is transmitted to the trigger point via a mechanical transmission structure (such as a lever, connecting rod, etc.), thereby triggering the on-off action. The conductive assembly 66 includes two sets of conductive plugs. The conductive plugs are installed on the top cover 62 and one end extends into the pressure measuring chamber 63. One set of conductive plugs is fixedly connected to a spring. The end of the spring away from the other set of conductive plugs is connected to the metal diaphragm via the aforementioned mechanical transmission structure. When the metal diaphragm deforms, the mechanical transmission structure drives the spring to contact or disengage from the other set of conductive plugs, thereby controlling the on-off of the waterway.

[0038] Furthermore, to prevent the fluid in the water outlet chamber 3 from entering the pressure measuring chamber 63 through the connecting tube 64 and causing the metal parts of the trigger assembly 65 to come into direct contact with the fluid and rust, in this embodiment, a flexible waterproof membrane 67 is provided at the bottom of the pressure measuring chamber 63 to cover and seal the connecting tube 64. The waterproof membrane 67 seals the connecting tube 64. When the air pressure in the water outlet chamber 3 changes, the deformation of the waterproof membrane 67 is transmitted to the pressure measuring chamber 63, changing the pressure in the pressure measuring chamber 63. This does not affect the detection of pressure changes by the trigger assembly 65, while also sealing the connecting tube 64 and preventing fluid from entering the pressure measuring chamber 63.
