Description

Technical Field

[0001] This utility model relates to a water passage structure capable of switching water channels. Background Technology

[0002] In modern water treatment and filtration systems, the water flow structure, as a key component, is widely used in various filtration devices and plays a vital role in filters, especially pre-filters. However, existing filtration devices have significant technical flaws in their operation. When users need to remove the filter element or its related accessories for cleaning or replacement, the water flow at the connection point often fails to remain open, causing a complete water circuit interruption. This design not only increases the complexity of operation for users but also severely impacts the user experience. For example, during the maintenance of a pre-filter, users must completely disassemble the device to close or open the water circuit, and when it needs to be reused, all components must be reinstalled. This cumbersome operating procedure greatly reduces the convenience and practicality of the equipment.

[0003] Furthermore, most filtration devices currently on the market use one-way valves to control the flow of water. While this design can achieve water path switching to some extent, it still has many shortcomings in practical applications. For example, when the filter element or accessories are removed, the water path cannot automatically switch to the backup channel to maintain normal water flow, causing users to be unable to use the water source normally during maintenance. This not only limits the functionality of the equipment but also causes unnecessary interference with users' daily water needs. Summary of the Invention

[0004] This utility model discloses a water passage structure that can switch water channels, aiming to solve the problems mentioned above.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

[0023] Referring to the attached diagram of the instruction manual, a water passage structure capable of switching water paths is provided. It achieves flexible switching between the first water path and the second water path through the rotation of the valve body, ensuring that the water path remains unobstructed under different usage conditions.

[0024] The overall structure of this utility model includes a top cover 1, a valve body 2, and a base 3. These components are assembled to form a complete device. The top cover 1 provides a channel for the introduction and discharge of water, and its top is provided with an inlet channel 6 and an outlet channel 7 for introducing water into the device and discharging it to a designated location. The valve body 2 is located between the top cover 1 and the base 3, and it is designed with a guide groove 8, an inlet hole 9, and an outlet hole 10, which are used to form the first water path and the second water path, respectively. The base 3 provides installation space for the valve body 2 and is connected to the top cover 1 by threads or other fixing methods to ensure the stability and sealing of the overall structure.

[0025] The design of the sealing ring is one of the key technologies of this utility model. The sealing ring consists of a first sealing ring 4 and a second sealing ring 5, which makes the first water path and the second water path independent water flows, and the two do not flow together. The first sealing ring 4 is arranged on the outer periphery of the guide groove 8, or it can be arranged on the outer periphery of the inlet and outlet holes as a whole; the second sealing ring 5 is arranged on the outer periphery of the inlet hole 9 and the outlet hole 10. This double sealing design effectively avoids leakage problems that may occur during water path switching, while improving the durability and stability of the device.

[0026] The first water path consists of the inlet channel 6 of the upper cover 1, the guide channel 8 of the valve body 2, and the outlet channel 7 of the upper cover 1. When the main body 11 is separated from the water connector, water flows in through the inlet channel 6, passes through the guide channel 8, and finally flows out through the outlet channel 7. In this state, the first water path is open, while the second water path is closed. This design ensures that the water path remains unobstructed even when the filter or related accessories are removed, thus significantly improving the user experience.

[0027] The second water path consists of the inlet channel 6 of the upper cover 1, the inlet hole 9 of the valve body 2, the main body 11 (which can be a filter element or related accessories), the outlet hole 10 of the valve body 2, and the outlet channel 7 of the upper cover 1. When the main body 11 is connected to the water connector, the water flows sequentially through the inlet channel 6, the inlet hole 9, the main body 11, and the outlet hole 10, finally flowing out from the outlet channel 7. In this state, the second water path is open, while the first water path is closed. In this way, the function of switching water paths can be completed without other auxiliary devices.

[0028] The valve body 2 can rotate relative to the upper cover 1, thereby switching between the first water path and the second water path. The main body 11 is equipped with an abutment plate 12, and the valve body 2 is equipped with a tongue plate 13. When the main body 11 and the valve body 2 are engaged, the abutment plate 12 and the tongue plate 13 contact each other and push the valve body 2 to rotate synchronously with the main body. Furthermore, the water connector is provided with a spiral surface 14, and the main body 11 is provided with a boss 15. When the main body 11 and the water connector rotate, the boss 15 moves along the spiral surface 14, causing the main body 11 to move up and down while rotating, thus ensuring the smoothness and reliability of the valve body 2's rotation.

[0029] The specific process of switching water channels is as follows: When the second water channel needs to be activated, the main body 11 is connected to the water connector. At this time, the boss 15 rotates along the spiral surface 14 and moves upward, causing the main body 11 to approach the valve body 2. As the main body 11 moves, the abutment piece 12 on it contacts the tongue piece 13 on the valve body 2 and pushes the valve body 2 to rotate to a specific angle, so that the inlet hole 9 is connected to the inlet channel 6 and the outlet hole 10 is connected to the outlet channel 7, thereby opening the second water channel. When switching to the first water channel needs to be activated, the main body 11 is separated from the water connector. At this time, the boss 15 rotates along the spiral surface 14 and moves downward, causing the main body 11 to move away from the valve body 2. As the main body 11 moves, the abutment piece 12 on it no longer applies force to the tongue piece 13. The valve body 2 rotates during these two processes but does not move up and down, so that the guide groove 8 is connected to the inlet channel 6 and the outlet channel 7, thereby opening the first water channel.

[0030] The innovation of this invention lies in its design that achieves water circuit switching through the rotation of the valve body 2. The rotation angle of the valve body 2 is controlled by the interaction between the abutment plate 12 on the main body 11 and the tongue plate 13 on the valve body 2, while the rotation direction of the valve body 2 is determined by the cooperation between the boss 15 on the main body 11 and the spiral surface 14 on the water connector. This design not only simplifies the water circuit switching operation process but also improves the overall reliability and service life of the device. Furthermore, by reasonably adjusting the inclination angle of the spiral surface 14 and the height of the boss 15, precise positioning of the valve body 2 at different angles can be achieved, thereby meeting different usage requirements. This method is similar to the method of screwing out and tightening a filter bottle, and will not be described in detail here.

[0031] This invention is applicable to various scenarios, including but not limited to applications requiring dynamic adjustment of water flow paths, such as filters and water purification equipment. Due to its compact structure and ease of maintenance, it can operate stably in different environments. For example, in a pre-filter, users can easily switch water paths by simply installing or removing the filter element, facilitating cleaning and replacement. Furthermore, the device has good expandability and can be customized to meet user needs, such as adding additional water channels or adjusting the rotation mechanism of valve body 2.

[0032] The technical advantages of this utility model are mainly reflected in the following aspects: First, the switching between the first and second water circuits is achieved by rotating the valve body 2, which solves the problem of water circuit interruption caused by the removal of filter elements or related accessories; second, the double sealing design ensures the sealing performance during the water circuit switching process and prevents water leakage; third, even when the filter element or other accessories are removed, the water circuit can still remain unobstructed, which significantly improves the user experience; finally, the overall structure is simple and easy to maintain, suitable for a variety of application scenarios, and has broad application prospects.

As previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments.
