[0038] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figure 1-Figure 6 The filtering device 100 according to the first aspect of the embodiment of the utility model is described.

[0039] like Figure 1 and Figure 2 As shown, the filtering device 100 according to the first embodiment of the utility model includes a housing 1 and a rotating member 2 .

[0040] Specifically, the housing 1 is formed with an inlet 11 and a plurality of outlets 12. In the description of the present utility model, "plurality" means two or more. The housing 1 defines a first cavity 13 and a second cavity 14. The first cavity 13 is located on a side of the second cavity 14 away from the outlet 12. The housing 1 has a first channel 15 and a second channel 16. The first channel 15 connects the first cavity 13 and the second cavity 14. The second channel 16 connects the second cavity 14 and one of the plurality of outlets 12. For example, in Figure 1 and Figure 2 In the example, the inlet 11 and the multiple outlets 12 are all located at the lower end of the housing 1, the first cavity 13 is located above the second cavity 14, the first channel 15 and the second channel 16 are both connected to the inlet 11, and cold water can be stored in the first cavity 13. In this way, the fluid (for example, normal temperature water) can flow from the inlet 11 through the second cavity 14 and then flow into the first cavity 13 along the first channel 15, and the fluid can also flow from the inlet 11 through the second cavity 14 and then flow out from the outlet 12 along the second channel 16 to the outside of the filter device 100, so that it is convenient to select the first channel 15 or the second channel 16 according to the actual use situation, thereby increasing the use range of the filter device 100.

[0041] Combination Figure 1 and Figure 2 One end of the rotating member 2 is located outside the housing 1, and the other end of the rotating member 2 passes through the first cavity 13 and the second cavity 14 and extends to another one of the multiple outlets 12. The interior of the rotating member 2 is respectively connected with the above-mentioned other one of the multiple outlets 12 and the first cavity 13. The rotating member 2 is provided with a first matching member 21 and a second matching member 22. The first matching member 21 is arranged adjacent to the first channel 15, and the second matching member 22 is arranged adjacent to the second channel 16. The rotating member 2 can rotate between the first position and the second position. When the rotating member 2 is located at the first position, the first matching member 21 opens the first channel 15, and the second matching member 22 closes the second channel 16. When the rotating member 2 is located at the second position, the first matching member 21 closes the first channel 15, and the second matching member 22 opens the second channel 16.

[0042] For example, in Figure 1 and Figure 2 In the example, two outlets 12 are formed, and the two outlets 12 are spaced apart in the left-right direction. The upper end of the rotating member 2 is located outside the shell 1, and the lower end of the rotating member 2 sequentially passes through the first cavity 13 and the second cavity 14 and extends to the outlet 12 on the right side (i.e., the other one of the multiple outlets 12). The first matching member 21 is located above the second matching member 22. When the user wants to drink cold water, the rotating member 2 is rotated to the first position. After the room temperature water flows from the inlet 11 into the second cavity 14, it can only flow into the first cavity 13 along the first channel 15. The room temperature water squeezes the cold water in the first cavity 13 and flows into the interior of the rotating member 2 and then flows to the outlet 12 on the right side. Then the cold water flows through the outlet 12 to the outside of the filter device 100 (such as Figure 2 When the user wants to drink normal temperature water, the rotating member 2 is rotated to the second position. After the normal temperature water flows from the inlet 11 into the second cavity 14, the first channel 51 is closed by the first matching member 21, and the normal temperature water can only flow out of the filter device 100 from the left outlet 12 (i.e., one of the multiple outlets 12) along the second channel 16 (e.g., Figure 1 The flow path indicated by the arrow B in the figure is the second path.

[0043] In this way, the flow path of the fluid can be switched by adjusting the rotating member 2, so that the user can choose to drink normal temperature water or cold water, which meets the multi-functional needs of the user and improves the user's experience. In addition, compared with the conventional technology of switching the fluid flow path by electronic control, the use of the rotating member 2 is simple and has a low cost, which reduces the manufacturing cost of the filter device 100, thereby facilitating the mass production of the filter device 100. In addition, the filter device 100 is simple to operate and is convenient for users to use.

[0044] According to the filter device 100 of the utility model, the flow path of the fluid can be switched by adjusting the rotating member 2, so that the user can choose to drink normal temperature water or cold water, which meets the multi-functional needs of the user and improves the user's experience. In addition, compared with the traditional technology of switching the fluid flow path by electronic control, the use of the rotating member 2 is simple and has a low cost, which reduces the manufacturing cost of the filter device 100, thereby facilitating the mass production of the filter device 100. In addition, the filter device 100 is simple to operate and is convenient for users to use.

[0045] According to some embodiments of the present invention, referring to Figure 2 , Figure 3 and Figure 4A first valve 151 movable along the axial direction of the first channel 15 is provided in the first channel 15, at least a portion of the first valve 151 extends into the second cavity 14, a first elastic member 152 is provided between the first valve 151 and the inner wall surface of the first channel 15, and the first elastic member 152 often pushes the first valve 151 to close the first channel 15. A second valve 161 movable along the axial direction of the second channel 16 is provided in the second channel 16, at least a portion of the second valve 161 extends into the second cavity 14, a second elastic member 162 is provided between the second valve 161 and the inner wall surface of the second channel 16, and the second elastic member 162 often pushes the second valve 161 to close the second channel 16.

[0046] For example, in Figure 2 , Figure 3 and Figure 4 In the example, the first valve 151 extends in the up-down direction, the first valve 151 can move in the up-down direction, the lower end of the first valve 151 extends into the second cavity 14, the lower end of the first elastic member 152 abuts against the first valve 151, the upper end of the first elastic member 152 abuts against the inner wall surface of the first channel 15, and the first elastic member 152 can push the first valve 151 to move downward to close the first channel 15. The second valve 161 extends in the up-down direction, the second valve 161 moves in the up-down direction, the upper end of the second valve 161 extends into the second cavity 14, the upper end of the second elastic member 162 abuts against the second valve 161, the lower end of the second elastic member 162 abuts against the inner wall surface of the second channel 16, and the second elastic member 162 can push the second valve 161 to move upward to close the second channel 16. In this way, the first channel 15 is closed by the first elastic member 152, so as to facilitate cutting off the first path. The second passage 16 is closed by the second elastic member 162, so as to facilitate cutting off the second path. In addition, the structure of the filter device 100 is simplified, and the production and use costs of the filter device 100 are reduced. It should be noted that the first elastic member 152 and the second elastic member 162 can both be springs.

[0047] Combination Figure 1 and Figure 2 When the rotating member 2 is located at the first position, the first matching member 21 pushes the first valve 151 to move to the side away from the outlet 12 to open the first channel 15, and the second elastic member 162 pushes the second valve 161 to move to the side away from the outlet 12 to close the second channel 16. When the rotating member 2 is located at the second position, the first elastic member 152 pushes the first valve 151 to move to the side adjacent to the outlet 12 to close the first channel 15, and the second matching member 22 pushes the second valve 161 to move to the side adjacent to the outlet 12 to open the second channel 16.

[0048] For example, when the rotating member 2 is located at the first position, the first matching member 21 pushes the first valve 151 to move upward so that the lower part of the first valve 151 is separated from the inner wall surface of the first channel 15 to open the first channel 15, and the second elastic member 162 pushes the second valve 161 to move upward so that the upper part of the second valve 161 abuts against the inner wall surface of the second channel 16 to close the second channel 16, that is, the first path is connected and the second path is closed. At this time, the normal temperature water can flow out as cold water along the first path (such as Figure 2 When the rotating member 2 is in the second position, the first elastic member 152 pushes the first valve 151 downward to make the lower part of the first valve 151 stop against the inner wall of the first channel 15 to close the first channel 15, and the second matching member 22 pushes the second valve 161 downward to separate the lower part of the second valve 161 from the inner wall of the second channel 16 to open the second channel 16, that is, the first path is closed and the second path is opened. At this time, normal temperature water can flow out along the second path (as shown in FIG. Figure 1 As shown by the middle arrow B), the user can drink water at room temperature. Thus, through the cooperation between the first elastic member 152 and the second elastic member 162 and the rotating member 2, the filter device 100 is easy to operate, so that it is easy to close the first path or the second path, reducing the difficulty of switching the fluid flow path, thereby helping to improve the operation speed of the filter device 100. For example, the first valve 151 and the second valve 161 can be set as water stop valves, but are not limited thereto.

[0049] According to some embodiments of the present invention, referring to Figure 1 and Figure 5 The first mating piece 21 is located on the side of the first channel 15 facing the outlet 12. The first mating piece 21 includes a first mating section 211 and a second mating section 212 connected to each other. The first mating section 211 is located on the side of the second mating section 212 away from the outlet 12. When the rotating member 2 is located in the first position, the first mating section 211 stops at least a portion of the first valve 151. When the rotating member 2 is located in the second position, the second mating section 212 stops at least a portion of the first valve 151.

[0050] For example, in Figure 1 and Figure 5In the example, the first fitting member 21 is located below the first channel 15. The first fitting segment 211 is located above the second fitting segment 212. When the rotating member 2 is located at the first position, the upper side surface of the first fitting segment 211 abuts against the lower side surface of the first valve 151, and the first elastic member 152 is in a compressed state, so that the first valve 151 opens the first channel 15. When the rotating member 2 rotates to the second position, since the second fitting segment 212 is lower than the first fitting segment 211, the rebound force of the first elastic member 152 pushes the first valve 151 to move downward, so that the lower end surface of the first valve 151 abuts against the upper side surface of the second fitting segment 212, so as to close the first channel 15. In this way, through the arrangement of the first matching section 211 and the second matching section 212, the first matching section 211 and the second matching section 212 can act on the first valve 151 during the rotation of the rotating member 2, pushing the first valve 151 to move in the up and down directions, effectively ensuring that the first valve 151 can open the first channel 15 or the first valve 151 can close the first channel 15, thereby facilitating the normal use of the filter device 100. In addition, the difficulty of operating the rotating member 2 is further reduced, thereby improving the working efficiency of the filter element 142 device. In addition, the rotating member 2 has a simple structure and is easy to produce and process, thereby reducing the use cost of the rotating member 2.

[0051] Combination Figure 1 and Figure 5 The second mating piece 22 is located on a side of the second channel 16 away from one of the multiple outlets 12. The second mating piece 22 includes a third mating segment 221 and a fourth mating segment 222 connected to each other. The third mating segment 221 is located on a side of the fourth mating segment 222 away from the outlet 12. When the rotating member 2 is located in the first position, the third mating segment 221 stops against at least a portion of the second valve 161. When the rotating member 2 is located in the second position, the fourth mating segment 222 stops against at least a portion of the second valve 161.

[0052] For example, in Figure 1 and Figure 5In the example of , the second matching member 22 is located above the second channel 16. The third matching segment 221 is located above the fourth matching segment 222. When the rotating member 2 is located at the first position, the upper end surface of the second valve 161 abuts against the lower surface of the third matching segment 221, and under the action of the second elastic member 162, a portion of the upper part of the second valve 161 abuts against the inner wall surface of the second channel 16 so that the second valve 161 closes the second channel 16. When the rotating member 2 rotates to the second position, the upper end surface of the second valve 161 abuts against the lower side surface of the fourth matching segment 222, and the fourth matching segment 222 presses the second valve 161 downward to separate a portion of the upper part of the second valve 161 from the inner wall surface of the second channel 16, and the second elastic member 162 is in a compressed state to open the second channel 16. In this way, through the arrangement of the third matching segment 221 and the fourth matching segment 222, it is effectively ensured that the second valve 161 can open the second channel 16 or the second valve 161 can close the second channel 16, thereby facilitating the normal use of the filter device 100. In addition, the difficulty of operating the rotating member 2 is further reduced, thereby improving the working efficiency of the filter element 142. In addition, the rotating member 2 has a simple structure and is easy to produce and process, thereby reducing the use cost of the rotating member 2.

[0053] According to some embodiments of the present invention, referring to Figure 5 A first connecting section 213 extending obliquely is provided between the first matching section 211 and the second matching section 212; and / or a second connecting section 223 extending obliquely is provided between the third matching section 221 and the fourth matching section 222. For example, Figure 5 In the example, the first connecting segment 213 extends obliquely from top to bottom, from the first matching segment 211 to the second matching segment 212, the upper end of the first connecting segment 213 is connected to one end of the first matching segment 211 close to the second matching segment 212, and the lower end of the first connecting segment 213 is connected to one end of the second matching segment 212 close to the first matching segment 211. The second connecting segment 223 extends obliquely from top to bottom, from the third matching segment 221 to the fourth matching segment 222, the upper segment of the second connecting segment 223 is connected to one end of the third matching segment 221 close to the fourth matching segment 222, and the lower segment of the second connecting segment 223 is connected to one end of the fourth matching segment 222 close to the third matching segment 221.

[0054] The arrangement of the first mating member 21 and the second mating member 22 includes the following situations: First, a first connecting section 213 extending obliquely is provided between the first mating section 211 and the second mating section 212. Second, a second connecting section 223 extending obliquely is provided between the third mating section 221 and the fourth mating section 222. Third, a first connecting section 213 extending obliquely is provided between the first mating section 211 and the second mating section 212, and at the same time, a second connecting section 223 extending obliquely is provided between the third mating section 221 and the fourth mating section 222. Such an arrangement facilitates the rotation of the rotating member 2 from the first position to the second position or from the second position to the first position along the central axis of the rotating member 2, thereby improving the smoothness of the rotation of the rotating member 2, and also improving the smoothness of the movement of the first valve 151 and the second valve 161, thereby further reducing the difficulty of switching between the first path and the second path, and improving the flexibility of switching between the first path and the second path. In addition, the first matching piece 21 and the second matching piece 22 have simple structures, which reduces the difficulty of producing the first matching piece 21 and the second matching piece 22, thereby improving the production efficiency of the rotating piece 2 and further reducing the production cost of the filter device 100.

[0055] According to some embodiments of the present invention, referring to Figure 2 and Figure 3 A step portion 214 is defined between one side of the outer peripheral surface of the first mating section 211 adjacent to the rotating member 2 and the second mating section 212. A guide channel 17 is formed on the shell 1. The guide channel 17 is located between the first cavity 13 and the second cavity 14. The other end of the rotating member 2 passes through the guide channel 17 and extends into the second cavity 14. The outer peripheral edge of one end of the guide channel 17 facing the outlet 12 stops at the step portion 214.

[0056] For example, in Figure 2 and Figure 3 In the example, the guide channel 17 connects the first cavity 13 and the second cavity 14, the lower end of the rotating member 2 passes through the guide channel 17 and extends into the second cavity 14, and the lower end outer peripheral edge of the side wall of the guide channel 17 stops at the step portion 214. Thus, the guide channel 17 facilitates the lower end of the steering member to pass through the first cavity 13 and the second cavity 14, thereby facilitating the fluid to flow out from the inside of the rotating member 2 along the right outlet 12, thereby facilitating the normal use of the filter element 142 device. In addition, the step portion 214 can avoid the side wall of the guide channel 17, thereby rationalizing the structure of the filter element 142 device, thereby facilitating the normal use of the filter element 142 device for a long time.

[0057] According to some embodiments of the present invention, referring to Figure 2 and Figure 5The rotating member 2 is formed with a through hole 23 penetrating the side wall of the rotating member 2, and a flow channel 24 is defined in the rotating member 2. The through hole 23 connects the flow channel 24 and the first cavity 13, and the flow channel 24 is connected to another one of the plurality of outlets 12. For example, in Figure 2 and Figure 5 In the example of FIG. 1 , the through hole 23 is formed on the side wall of the portion of the rotating member 2 located in the first cavity 13, the flow channel 24 extends in the up-down direction, the flow channel 24 passes through the lower end of the rotating member 2, the upper part of the flow channel 24 is connected to the through hole 23, and the lower end of the flow channel 24 is connected to the outlet 12 on the right side. As a result, the fluid in the first cavity 13 can flow from the flow channel 24 along the through hole 23 to the outlet 12, and then flow from the outlet 12 to the outside of the filter element 142 device (such as Figure 2 The through hole 23 and the flow channel 24 are simple in structure, which further reduces the difficulty of producing the rotating member 2, thereby helping to improve the production efficiency of the rotating member 2.

[0058] According to some embodiments of the present invention, referring to Figure 1 , a knob 25 is provided at one end of the rotating member 2. For example, Figure 1 In the example, the knob 25 is located on the outer side of the upper end of the housing 1, and the cross-section of the upper end of the rotating member 2 is roughly hexagonal. The knob 25 is interference-fitted with the upper end of the rotating member 2, and the rotating member 2 can be driven to rotate together by rotating the knob 25. For example, when the knob 25 rotates clockwise, the rotating member 2 also rotates clockwise from the second position to the first position to connect the first path and close the second path. When the knob 25 rotates counterclockwise, the rotating member 2 also rotates counterclockwise from the first displacement to the second position to connect the second path and close the first path. In this way, through the cooperation of the knob 25 and the rotating member 2, the switching of the first path and the second path can be adjusted mechanically, which is different from the conventional technology of switching the flow path electrically, thereby reducing the production cost of the filter device 100. Moreover, it is also convenient for the user to choose to use cold water or normal temperature water by rotating the knob 25, thereby improving the user's experience.

[0059] According to some embodiments of the present invention, referring to Figure 1 The second cavity 14 has a water inlet flow path 141, which is connected to the inlet 11. Thus, the fluid enters the second cavity 14 from the inlet 11 along the water inlet flow path 141, thereby effectively ensuring that the fluid can enter the second cavity 14, and thus the filter device 100 can be used normally.

[0060] According to some embodiments of the present invention, referring to Figure 1A filter element 142 is disposed in the second cavity 14. The filter element 142 is disposed around the outer circumference of the rotating member 2. A water inlet flow path 141 is defined between the outer circumference of the filter element 142 and the inner wall of the housing 1. Figure 1 In the example, the cross-sectional shape of the filter element 142 is roughly annular. The fluid flows from the inlet 11 along the water inlet flow path 141 to the outer peripheral surface of the filter element 142, and then the fluid enters between the inner peripheral side of the filter element 142 and the outer peripheral side of the rotating member 2 through the filter element 142. Subsequently, the fluid can flow from the first channel 15 into the first cavity 13 or flow out from the second channel 16 to the outlet 12 on the left. In this arrangement, the fluid can flow out from multiple outlets 12 after passing through the filter element 142. The filter element 142 filters the fluid, thereby improving the cleanliness of the fluid, making it easier for users to drink, and effectively ensuring the health of users. In addition, it also improves the user's drinking experience.

[0061] Optionally, refer to Figure 2 and Figure 3 , a first pressure block 153 is provided at the first channel 15, a first flow hole 1531 is formed on the first pressure block 153, the first flow hole 1531 penetrates the upper side and the lower side of the first pressure block 153 in the up-down direction, the upper end of the first valve 151 extends into the first flow hole 1531, a first groove 1511 is formed on the outer peripheral surface of the first valve 151, and a first sealing ring 1512 is provided at the first groove 1511. For example, in Figure 2 and Figure 3 In the example, the first elastic member 152 is sleeved outside the upper end of the first valve 151, the lower end of the first elastic member 152 abuts against the first valve 151, the upper end of the first elastic member 152 abuts against the lower side surface of the first pressing block 153, and the outer peripheral surface of the upper end of the first pressing block 153 is interference fit with the side wall of the first channel 15. The cross-sectional area of ​​the middle region of the first valve 151 is larger than the cross-sectional areas of the lower end region and the upper end region of the first valve 151, the first groove 1511 is formed on the outer peripheral surface of the middle region of the first valve 151, and the lower surface of the middle region of the first valve 151 and the side wall of the first channel 15 are separably matched. After the fluid flows from the second cavity 14 into the first flow hole 1531 along the first channel 15, it flows into the first cavity 13.

[0062] With such a configuration, the first flow hole 1531 can not only allow the fluid to pass through, but also guide the first valve 151, thereby preventing the first valve 151 from swinging during the movement. The first valve 151 can also prevent the first elastic member 152 from swinging during the movement, thereby improving the stability of the first valve 151 and the first elastic member 152 during the movement, and improving the use stability of the filter device 100. In addition, the first groove 1511 can allow the first sealing ring 1512 to move up and down with the first valve 151, so that when the first valve 151 closes the first channel 15, the first sealing ring 1512 contacts the side wall of the first channel 15, thereby improving the sealing of the first valve 151 in closing the first channel 15, thereby effectively ensuring the closure of the first path.

[0063] Combination Figure 2 and Figure 4 , a second pressure block 163 is provided at the second channel 16, a second flow hole 1631 is formed on the second pressure block 163, the second flow hole 1631 penetrates the upper side and the lower side of the second pressure block 163 in the up-down direction, the lower end of the second valve 161 extends into the second flow hole 1631, a second groove 1611 is formed on the outer circumference of the second valve 161, and a second sealing ring 1612 is provided at the second groove 1611. For example, in Figure 2 and Figure 4 In the example, the second elastic member 162 is sleeved outside the lower end of the second valve 161, the upper end of the second elastic member 162 abuts against the second valve 161, the lower end of the second elastic member 162 abuts against the upper side surface of the second pressing block 163, and the outer peripheral surface of the lower end of the second pressing block 163 is interference fit with the side wall of the second channel 16. The cross-sectional area of ​​the middle region of the second valve 161 is larger than the cross-sectional areas of the lower end region and the upper end region of the second valve 161, and the second groove 1611 is formed on the outer peripheral surface of the middle region of the second valve 161, and the upper side surface of the middle region of the second valve 161 and the side wall of the second channel 16 are separably matched. After the fluid flows from the second cavity 14 along the second channel 16 into the second flow hole 1631, it flows to the outlet 12 on the left.

[0064] With such a configuration, the second flow hole 1631 can not only allow the fluid to pass through, but also guide the second valve 161, thereby preventing the second valve 161 from swinging during the movement. The second valve 161 can also prevent the second elastic member 162 from swinging during the movement, thereby improving the stability of the second valve 161 and the second elastic member 162 during the movement, and improving the use stability of the filter device 100. In addition, the second groove 1611 can allow the second sealing ring 1612 to move up and down with the second valve 161, so that when the second valve 161 closes the second channel 16, the second sealing ring 1612 contacts the side wall of the second channel 16, thereby improving the sealing of the second valve 161 closing the second channel 16, thereby effectively ensuring the closure of the second path.

[0065] Optionally, refer to Figure 2 , Figure 4 and Figure 5 , a receiving groove 26 is formed on the outer peripheral surface of the lower end of the rotating member 2, and a third sealing ring 27 is provided in the side wall of the receiving groove 26. Therefore, after the lower end of the rotating member 2 is assembled with the housing 1, the third sealing ring 27 contacts the housing 1 opposite to the lower end of the rotating member 2, thereby improving the sealing performance of the assembly of the rotating member 2 and the housing 1, preventing the fluid from flowing out from between the rotating member 2 and the housing 1, and improving the sealing performance of the filter device 100. In addition, the receiving groove 26 can limit the third sealing ring 27, thereby preventing the third sealing ring 27 from moving during the assembly process of the rotating member 2 and the housing 1, reducing the difficulty of assembling the rotating member 2 and the housing 1, and improving the assembly efficiency of the filter device 100.

[0066] Optionally, refer to Figure 2 and Figure 4 A fourth sealing ring 28 is provided between the outer circumference of the rotating member 2 and the inner wall of the guide channel 17. The fourth sealing ring 28 is sleeved on the outer circumference of the rotating member 2. A sealing gasket 29 is provided on the lower side of the fourth sealing ring 28. The sealing gasket 29 is sleeved on the outer circumference of the rotating member 2. The lower side of the sealing gasket 29 abuts against the upper side of the second matching section 212. The outer circumference of the sealing gasket 29 abuts against the step portion 214. The edge of the upper side of the sealing gasket 29 is connected to the lower side of the side wall of the guide channel 17. Thus, the sealing performance of the rotating member 2 and the guide channel 17 is improved, thereby preventing the fluid from flowing along the outer circumference of the rotating member 2 and the inner side wall of the guide channel 17, and further improving the sealing performance of the filter device 100.

[0067] Optionally, refer to Figure 2 , Figure 3 , Figure 4 and Figure 6The lower end surface of the side wall of the first channel 15 is connected to a plurality of first protrusions 154, and the plurality of first protrusions 154 are arranged at intervals along the circumference of the side wall of the first channel 15. The upper end surface of the side wall of the second channel 16 is connected to a plurality of second protrusions 164, and the plurality of second protrusions 164 are arranged at intervals along the circumference of the side wall of the second channel 16. For example, Figure 2 , Figure 3 , Figure 4 and Figure 6 In the example, there are four first protrusions 154. When the rotating member 2 is in the first position, the lower side of the first protrusion 154 abuts against the upper side of the first matching segment 211, and the fluid flows from the second cavity 14 along the gap between two adjacent first protrusions 154 into the first channel 15. There are four second protrusions 164. When the rotating member 2 is in the second position, the upper side of the second protrusion 164 abuts against the lower side of the fourth matching segment 222, and the fluid flows from the second cavity 14 along the gap between two adjacent second protrusions 164 into the second channel 16. Such a configuration effectively ensures the communication between the first channel and the second channel, thereby facilitating the flow of fluid and facilitating drinking by users.

[0068] The working process of the filter device 100 is roughly as follows:

[0069] When the user wants to drink cold water, the knob 25 is rotated clockwise to rotate the rotating member 2 from the second position to the first position. During the rotation, the first valve 151 moves to the first matching section 211, and at the same time, the first valve 151 moves upward to open the first channel 15. The first elastic member 152 is in a compressed state, and the second elastic member 162 pushes the second valve 161 to move upward to close the second channel 16. At this time, the first path is connected and the second path is closed. Normal temperature water flows from the inlet 11 along the water inlet channel to the outer peripheral surface of the filter element 142, and then the fluid flows through the filter element 142 to the inner peripheral surface of the filter element 142 and the outer peripheral surface of the rotating member 2, and then flows from the gap between the two adjacent first protrusions 154 along the first channel 15 into the first cavity 13. The normal temperature water squeezes the cold water in the first cavity 13 from the through hole 23 into the flow channel 24, and the cold water flows along the flow channel 24 to the outlet 12 on the right side, and the fluid is discharged from the outlet 12 on the right side to the outside of the filter element 142 device (such as Figure 2 (as indicated by arrow A).

[0070] When the user wants to drink normal temperature water, the knob 25 is rotated counterclockwise to rotate the rotating member 2 from the first position to the second position. During the rotation, the lower end of the second valve 161 moves to the fourth matching section 222, and the second valve 161 moves downward to open the second channel 16. The second elastic member 162 is in a compressed state, and the first elastic member 152 pushes the first valve 151 to move downward to close the first channel 15. At this time, the second path is connected and the first path is closed. Normal temperature water flows from the inlet 11 along the water inlet channel to the outer peripheral surface of the filter element 142, and then the fluid flows through the filter element 142 to the inner peripheral surface of the filter element 142 and the outer peripheral surface of the rotating member 2, and then flows from the gap between the two adjacent second protrusions 164 along the second channel 16 to the outlet 12 on the left, and the fluid is discharged from the outlet 12 on the left to the outside of the filter element 142 device (such as Figure 1 (indicated by arrow B in the middle).
