Description

Technical Field

[0001] This utility model relates to the field of water purification equipment technology, specifically to an integrated drain valve seat structure that combines raw water and concentrated water. Background Technology

[0002] With increasing health awareness and the widespread use of water purifiers, an instant countertop water purifier and heater has emerged and is gaining a growing market share, bringing great convenience to people's hot water needs. However, due to the complex structure of the raw water tank and the return of concentrated water, they are generally too large and not compact enough. Without a return port to help return concentrated or cold water, water resources will be wasted. Furthermore, while the purified water filtered by the RO filter flows into the water tank, the unfiltered concentrated water has nowhere to go and can only be discharged, polluting the environment.

[0003] Therefore, in order to ensure the rational use of water resources, it is necessary to ensure that the valve body connected to the bottom of the raw water tank can realize the output of raw water and the return of concentrated water. However, this type of four-way valve body structure occupies a lot of space and affects the overall appearance of the water purifier, so it is necessary to improve the structure of the four-way valve body. Utility Model Content

[0004] The purpose of this utility model is to minimize the size of the four-way valve body connected to the bottom of the raw water tank while ensuring the sealed raw water outlet and concentrated water return functions, and to allow the raw water tank to be freely disassembled for water replacement. We have designed an integrated raw water and concentrated water drain valve seat structure.

[0005] The technical solution adopted to solve the above problems is:

[0006] An integrated raw water and concentrated water drain valve seat structure includes a raw water tank and a drain valve seat connected to a water purifier frame. The drain valve seat is detachably and sealed to a bidirectional interface located at the bottom of the raw water tank.

[0007] The raw water tank has an opening at the bottom, which connects to an upper flow channel inside the tank. The opening also has a lower flow channel connecting to a lower valve seat. An extension pipe for separating concentrated water and raw water is installed inside the upper flow channel, with a gap between the upper flow channel and the extension pipe to allow for concentrated water recirculation. A valve core for separating concentrated water and raw water is installed inside the lower flow channel.

[0008] The valve core is sealed to the inner wall of the opening by an O-ring. The valve core has a raw water outlet and a concentrated water return outlet at its center. A sealing ring is fitted inside the raw water outlet, and this sealing ring is sealed to the raw water inlet conduit on the drain valve body, supplying raw water from the raw water tank to the drain valve body.

[0009] The drain valve body is provided with a support that mates with the drain channel. The inner wall of the support is provided with a sealing element that conforms to the shape of the drain channel. When the raw water tank mates with the drain valve body, the conforming sealing element seals the drain channel and the support tightly. The support is provided with a raw water outlet pipe and a concentrated water return hole. The raw water outlet pipe is connected to the raw water outlet pipeline below, and the concentrated water return hole is connected to the concentrated water return pipeline below.

[0010] Furthermore, the inner wall array of the upper flow channel is provided with external buckles, which engage with the internal buckles provided on the outer wall of the extension pipe. This ensures the stable fit of the extension pipe while facilitating the flow of concentrated water from the lower valve body through the gap between the outer wall of the extension pipe and the upper flow channel into the bottom of the raw water tank.

[0011] Furthermore, the extension pipe is equipped with a raw water check valve to prevent raw water leakage from the raw water tank. The raw water check valve is opened by pushing through the raw water outlet pipe.

[0012] Furthermore, a high-level check valve for concentrated water is installed in the concentrated water return hole to prevent leakage of concentrated water from the raw water tank. The high-level check valve for concentrated water is opened by pushing it with an upper push rod installed on the lower water valve body.

[0013] Furthermore, a bottom check valve for preventing concentrated water leakage is installed between the concentrated water return pipeline and the concentrated water return hole. The bottom check valve for concentrated water is opened by a push rod installed below the concentrated water return hole through a push-pull mechanism.

[0014] Furthermore, a redundant interface is provided below the raw water outlet pipe to accommodate raw water NTC or TDS detection sensors.

[0015] The beneficial effects of this utility model are:

[0016] This integrated raw water and concentrated water valve seat structure uses two sets of check valves to separate the raw water outlet and concentrated water inlet. The valve core is used to miniaturize and improve the flow channels of the two sets of flow channels, which greatly compresses the flow channel layout of raw water and concentrated water, and does not affect the free disassembly and replacement of the raw water tank, making it practical and convenient.

[0027] Please see Figures 1 to 2 This embodiment proposes an integrated raw water and concentrated water drain valve seat structure, including a raw water tank 1 and a drain valve seat 4 connected to the water purifier frame. The drain valve seat 4 and the bidirectional interface at the bottom of the raw water tank 1 are detachably and sealed together. The bottom of the raw water tank 1 is provided with an opening 2, which is connected to an upper flow channel inside the raw water tank 1. The opening 2 is also provided with a lower flow channel connected to the drain valve seat 4. An extension pipe 3 for separating concentrated water and raw water is provided inside the upper flow channel, and the upper flow channel and the extension pipe 3 are connected with a gap for the return of concentrated water. A valve core for separating concentrated water and raw water is provided inside the lower flow channel.

[0028] See Figure 3 and Figure 4 The valve core and the inner wall of the opening 2 are sealed together by an O-ring 13.

In particular, the concentrated water return hole is provided with a concentrated water upper check valve 16 to prevent concentrated water leakage in the raw water tank. The concentrated water upper check valve 16 is pushed by the upper push rod 7 of the drain valve body to achieve conduction.

[0029] See Figure 4 and Figure 8 The drain valve body is provided with a support 5 that mates with the drain channel. The inner wall of the support 5 is provided with a sealing element 22 that conforms to the shape of the drain channel. When the raw water tank 1 mates with the drain valve body, the sealing element 22 seals the drain channel and the support 5 tightly. The support is provided with a raw water outlet pipe 6 and a concentrated water return hole. The raw water outlet pipe 6 is connected to the raw water outlet pipeline 11 below, and the concentrated water return hole is connected to the concentrated water return pipeline 10 below.

[0030] It should be noted that, see reference Figure 6 and Figure 8 The inner wall of the upper channel is provided with an outer buckle 18, which engages with the inner buckle 17 on the outer wall of the extension pipe 3. This ensures the stable operation of the extension pipe 3 and allows the concentrated water flowing up from the drain valve body to pass through the gap between the outer wall of the extension pipe 3 and the upper channel and flow into the bottom of the raw water tank 1.
