Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of water inlet valve, especially to a bottom side water inlet interchanging water inlet valve with filter. BACKGROUND

[0002] Since the water flow in the water inlet channel flows towards the water outlet channel, impurities mixed in the water flow will be gathered on the stop valve of the water outlet channel, causing the stop valve to leak and fail. To solve this problem, a filter screen is generally inserted into the water inlet channel in the prior art, so that the water flow in the water inlet channel can only flow to the stop valve after being filtered by the filter screen, avoiding the accumulation of impurities on the stop valve. In addition, during the installation of the toilet, the on-site installation conditions may not match the water inlet channel on the toilet water inlet valve, so two water inlet channels are generally provided on the water inlet valve, one for bottom water inlet and the other for side water inlet, so that one of the two water inlet channels can be matched according to the on-site conditions. However, there is a problem of filtering the water flow in the two water inlet channels. If a filter screen is installed in each of the two water inlet channels, it will increase the cost and cause many inconveniences, thus leading to the present case. SUMMARY

[0029] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Unless otherwise expressly defined, the use of directional terms such as "center," "lateral," "longitudinal," "horizontal," "vertical," "top," "bottom," "inner," "outer," "upper," "lower," "front," "rear," "left," "right," "clockwise," and "counterclockwise" in the claims, description, and accompanying drawings of this utility model is merely for the convenience of describing the utility model and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it should not be construed as limiting the specific protection scope of this utility model.

[0031] like Figures 1-10 As shown, this utility model provides a bottom-side water inlet interchangeable inlet valve with filter, including a valve body 1 and a filter body 2; the valve body 1 forms at least two water inlet channels 3 and one water outlet channel 4, both water inlet channels 3 are connected to the water outlet channel 4, the water inlet channels 3 are connected to a water source, which can be an external tap water source, and the water outlet channel 4 is connected to the toilet tank, and a stop valve 5 is provided on the water outlet channel 4, the stop valve 5 is used to open or close the water outlet channel 4, after the water outlet channel 4 is opened, the water outlet channel 4 can fill water into the toilet tank; the stop valve 5 can be any existing type capable of A back pressure valve is used to control the fluid pressure in the water flow channel. The back pressure valve has a pressure relief hole. The inlet valve is also equipped with a float assembly 12, which is connected to a stop valve 5. The float assembly 12 moves up and down in the toilet tank with the water level. When the float assembly 12 moves up, it can drive the stop valve 5 to close the water outlet channel 4. When the float assembly 12 moves down, it can drive the stop valve 5 to open the water outlet channel 4. The up and down movement of the float assembly 12 drives the stop valve 5 to open or close the pressure relief hole, thereby opening or closing the water outlet channel 4. This is the prior art and will not be described in detail.

[0032] Key points combined Figure 1As shown, the two water inlet channels 3 are the first water inlet channel 6 and the second water inlet channel 7, respectively. The first water inlet channel 6 and the second water inlet channel 7 are connected to the water source. The first water inlet channel 6 extends longitudinally, and its inlet is located on the bottom side of the valve body 1, forming a bottom water inlet. The second water inlet channel 7 extends laterally, and its outer end is provided with an inlet, forming a side water inlet. The filter body 2 is set at the water outlet channel 4 and is located between the stop valve 5 and the two water inlet channels 3. That is, the filter body 2 can be set at any position on the water outlet channel 4 between the stop valve 5 and the two water inlet channels 3, so that the water flow in the first water inlet channel 6 can only flow through the filter body 2 for filtration before flowing towards the stop valve 5, and the water flow in the second water inlet channel 7 can only flow through the filter body 2 for filtration before flowing towards the stop valve 5.

[0033] Key points combined Figures 2-4 As shown, the first water inlet channel 6 and the second water inlet channel 7 are both connected to the water outlet inlet 41. Preferably, the filter body 2 is set at the water outlet inlet 41. The water outlet inlet 41 is directly blocked by the filter body 2. In this way, the water in any water inlet channel 3 will be filtered by the filter body 2 before flowing into the water outlet inlet 41 and then flow towards the stop valve 5, so as to avoid impurities from flowing towards the stop valve 5 and accumulating there, thus preventing the stop valve 5 from malfunctioning.

[0034] Preferably, the filter body 2 is detachably installed at the water outlet channel 4 so that the filter body 2 can be removed for cleaning; to facilitate the installation and removal of the filter body 2, a socket 8 is provided on the side wall of the valve body 1, and the socket 8 extends into the valve body 1 to form an installation channel 9, which extends to the water outlet channel 4, and then is further connected. Figure 2 As shown, the inlet 8 is located at the top of the valve body 1. In the case of limited water tank space, it is convenient to disassemble and assemble the filter body 2. The installation channel 5 extends longitudinally. The filter body 2 has a connecting section 21 and a filter section 22 formed in sequence. After the filter body 2 is inserted into the installation channel 9 through the inlet 8, it can be positioned and installed in the installation channel 9. The connecting section 21 blocks the inlet 8. Specifically, the connecting section 21 is sealed with the inner wall of the installation channel 9 by a sealing ring. The sealing ring can be made of PVC material or rubber material to prevent the water in the valve body 1 from overflowing from the inlet 8. The filter section 22 blocks the water inlet 41 of the outlet channel. In this way, the water flow in the first water inlet channel 6 and the water flow in the second water inlet channel 7 must be filtered by the filter body 2 before flowing towards the stop valve 5 when passing through the water inlet 41 of the outlet channel.

[0035] In this specific embodiment, the filter body 2 and the mounting channel 9 are rotated and snapped together. Specifically, as shown below... Figure 4 and Figure 10As shown, the outer surface of the filter body 2 has a protruding locking protrusion 25. The inner wall of the installation channel 9 has an annularly spaced annular locking groove 91 and a clearance area 92. The clearance area 92 is used to allow the locking protrusion 25 to pass through. During installation, the locking protrusion 25 of the filter body 2 is aligned with the clearance area 92 and inserted. After the filter body 2 is inserted and positioned, the filter body 2 is rotated to allow the locking protrusion 25 to slide into the groove of the locking protrusion 91 (e.g., ...). Figure 4 As shown in the figure, the filter body 2 is then fixed in the mounting channel 9. Of course, in other embodiments, a slot can be formed on the filter body 2 and a protrusion can be formed on the inner side wall of the mounting channel 9, and the two can also be rotated and snapped together. There is no specific limitation. In addition, the filter body 2 and the mounting channel 9 can also be fixed in other ways. There is no specific limitation. In order to facilitate the rotation of the filter body 2, an end cap 23 is also formed at the top of the filter body 2. The end cap 23 is placed on the socket 8 to prevent dust or impurities from clogging the socket 8. A handle 24 is also formed on the end cap 23. The handle is used for hand to turn or hold so that the filter body 2 can be rotated through the handle 24, and at the same time, it is convenient to insert or pull the filter body 2 into or out of the mounting channel 9.

[0036] Key points combined Figures 5-8 As shown, it also includes a plug 10, which is used to block one of the first water inlet channel 6 and the second water inlet channel 7, so that the other of the first water inlet channel 6 and the second water inlet channel 7 is in an open state. The connection between the plug 10 and the water inlet channel 3 is a rotary snap-fit, specifically using the rotary snap-fit ​​method between the filter body 2 and the installation channel 9 mentioned above, but other connection methods can also be used. Since the first water inlet channel 6 is a bottom water inlet and the second water inlet channel 7 is a side water inlet, in specific use, when it is necessary to connect through the bottom water inlet, the second water inlet channel 7 is blocked by the plug 10, so that the first water inlet channel 6 is connected to the water source; when it is necessary to connect through the side water inlet, the first water inlet channel 6 is blocked by the plug 10, so that the second water inlet channel 7 is connected to the water source, realizing the interchangeability of the first water inlet channel 6 and the second water inlet channel 7, so that the water inlet valve can flexibly adapt to the installation environment and has high adaptability.

[0037] It also includes a water inlet connector 11, which connects one of the first water inlet channel 6 and the second water inlet channel 7 to a water source. When the plug 10 blocks one of the first water inlet channel 6 and the second water inlet channel 7, the water inlet connector 11 connects to the other of the first water inlet channel 6 and the second water inlet channel 7. Specifically, a water flow channel 112 runs through the water inlet connector 11, extending to both ends of the water inlet connector 11. An external thread is formed on the outer periphery of the water inlet connector 11, connecting it to an external water source device via the thread, allowing the water source to connect to one of the two water inlet channels 3 through the water inlet connector 11. The connection between the water inlet connector 11 and the water inlet channel 3 is a rotary snap-fit, specifically using the rotary snap-fit ​​method described above between the filter body 2 and the installation channel 9. Of course, other connection methods are also possible. (Focus on...) Figures 5-6 The diagram shows a side-inlet water intake method. The inlet connector 11 connects to the second inlet channel 7, and the plug 10 seals the inlet of the first inlet channel 7. Water flows from the second inlet channel 7 into the outlet channel 4. (Focus on...) Figures 7-8 As shown, the bottom water inlet method is demonstrated. The water inlet connector 11 is connected to the first water inlet channel 6, and the plug 10 is sealed at the water inlet of the second water inlet channel 6. The water flows from the first water inlet channel 6 into the water outlet channel 4.

[0038] In this specific embodiment, after the plug 10 blocks the water inlet channel 3, it can be embedded inside the water inlet channel 3 to prevent the outer end of the plug 10 from protruding outward from the water inlet channel 3 (e.g., Figure 5 and Figure 7 (As shown), but this would make it inconvenient to directly disassemble the plug 10. In order to facilitate the disassembly and assembly of the plug 10, the focus is on combining... Figure 9 As shown, a first mating portion 101 is formed on the plug 10, so that after the plug 10 is connected to one of the water inlet channels 3, the first mating portion 101 is exposed in the water inlet channel 3. A second mating portion 111 is formed on the water inlet connector 11 to mate with the first mating portion 101, so that after the second mating portion 111 mates with the first mating portion 101, the water inlet connector 11 can rotate the plug 10 to be connected to the water inlet channel 3, or rotate the plug 10 in the opposite direction to remove it from the water inlet channel 3, which is convenient for disassembly and installation. No additional tools are needed to disassemble and install the plug; the water inlet connector 11 can be directly used as a tool for disassembling and installing the plug 10. Figure 8As shown, the first mating part 101 is a protrusion, and the second mating part 111 is a groove. The protrusion and the groove are interference-fitted so that after the protrusion is inserted into the groove, the water inlet connector 11 is connected and fixed to the plug 10. Of course, in other embodiments, the first mating part 101 can be a groove and the second mating part 111 can be a protrusion, without specific limitation. In addition, the outer contour of the cross-section of the protrusion is a regular hexagonal structure, and the inner contour of the cross-section of the groove is also a regular hexagonal structure. Of course, in other embodiments, it can also be other shapes, such as quadrilaterals or pentagons, etc. There is no specific limitation as long as it can fix the water inlet connector 11 to the plug 10. Of course, in other embodiments, the first mating part 101 and the second mating part 111 can also be other mating methods, without specific limitation.

[0039] The above description is only a preferred embodiment of this utility model and is not intended to limit the design of this case. All equivalent changes made based on the key design of this case shall fall within the protection scope of this case.
