[0021] The technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0022] It should be noted that all directional indications in the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. In addition, the descriptions of "preferred", "sub-preferred", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "preferred" or "sub-preferred" may explicitly or implicitly include at least one such feature.

[0023] Reference Figures 1 to 6 The utility model proposes a water inlet and outlet fitting of a water pump, characterized in that it comprises a connecting plate 1, a switch member 2, a water inlet pipe 3 and a water outlet pipe 4 installed on the connecting plate 1, a first valve core 51 is arranged in the water inlet pipe 3, a second valve core 52 is arranged in the water outlet pipe 4, a first connecting member 21 connected to the first valve core 51 and a second connecting member 22 connected to the second valve core 52 are arranged on the switch member 2, and when the switch member 2 rotates relative to the connecting plate 1, the first valve core 51 and the second valve core 52 are synchronously rotated to open and close the water inlet pipe 3 and the water outlet pipe 4. By rotating the switch member 2, the water inlet pipe 3 and the water outlet pipe 4 can be opened and closed at the same time, which is very convenient and quick to use.

[0024] Preferably, the first valve core 51 and the second valve core 52 are both ball valves.

[0025] Reference Figure 3 The water inlet pipe 3 includes an upper pipe 31 and a lower pipe 32. The lower pipe 32 includes a water-passing section 321 and a valve section 322 located above the water-passing section 321. The diameter of the valve section 322 is larger than the diameter of the water-passing section 321. The first valve core 51 is installed in the valve section 322. The upper end of the water-passing section 321 is provided with an arc surface 3211 that fits with the outer wall of the first valve core 51. The lower end of the upper pipe 31 is inserted into the valve section 322 of the lower pipe 32. A first sealing ring 61 is provided between the first valve core 51 and the upper pipe 31. The first valve core 51 has a through hole. When the through hole is in a vertical state, the water-passing sections 321 of the upper pipe 31 and the lower pipe 32 are connected. After the first valve core 51 rotates 90 degrees, the through hole is in a horizontal state, and the water-passing sections 321 of the upper pipe 31 and the lower pipe 32 are blocked.

[0026] Preferably, an outer wall of the upper tube 31 is provided with an outer thread, and an inner wall of the valve section 322 is provided with an inner thread, so that the upper tube 31 and the valve section 322 are screwed. A connecting seat 301 is provided on the outer wall of the valve section 322, and the connecting seat 301 and the connecting plate 1 are connected by screws. This design makes it easy to remove the upper tube 31 and the lower tube 32 from the connecting plate 1, and then inspect and clean the first valve core 51, the first sealing ring 61 and other components inside.

[0027] Reference Figure 2 and Figure 4 The outer wall of the valve section 322 is provided with a cylinder 302, the first connecting member 21 penetrates the cylinder 302 and is plugged with the first valve core 51, and a second sealing ring 62 is provided between the cylinder 302 and the first connecting member 21. Specifically, a plug hole is provided on the first valve core 51, and a plug block matching with the plug hole is provided on the first connecting member 21. The plug hole can be an oblong hole, a square hole, a hexagonal hole, etc., as long as it is not a round hole.

[0028] The water inlet pipe 3 and the water outlet pipe 4 are both water pipes. As a further improvement of the present invention, a limiting structure capable of limiting the rotation range of the switch member 2 is provided between at least one water pipe and the switch member 2. The limiting structure may be provided only between the water inlet pipe 3 and the switch member 2, or only between the water outlet pipe 4 and the switch member 2, or both between the water outlet pipe 4 and the switch member 2 and between the water inlet pipe 3 and the switch member 2.

[0029] Reference Figure 6 In a preferred embodiment of the present invention, the limiting structure between the water inlet pipe 3 and the switch member 2 includes a protrusion 7 arranged on the outer wall of the water inlet pipe 3, and an arc groove 201 arranged on the switch member 2. The arc groove 201 is a closed groove with both ends closed. The protrusion 7 is inserted in the arc groove 201. When the switch member 2 rotates, the protrusion 7 moves in the arc groove 201 relative to the switch member 2. When the protrusion 7 moves to the head end of the arc groove 201 relative to the switch member 2, the first valve core 51 and the second valve core 52 are both opened. When the protrusion 7 moves to the end of the arc groove 201 relative to the switch member 2, the first valve core 51 and the second valve core 52 are both closed. The rotation range of the switch member 2 can be limited by the two ends of the arc groove 201, so that when the switch member 2 rotates, it can accurately rotate to the open state or the closed state with the two valve cores. In addition, the arc groove 201 can also play a guiding role, so that the switch member 2 can rotate smoothly.

[0030] Furthermore, the switch member 2 has a handle 23. The setting of the handle 23 can strengthen the force arm of the switch member 2 and facilitate the user to bend the switch member 2, so that the user only needs one finger to bend the switch member 2 to open and close the water inlet pipe 3 and the water outlet pipe 4.

[0031] Furthermore, the connecting plate 1 is provided with an elongated hole 101, and the handle 23 is inserted into the elongated hole 101. When the handle 23 is rotated to the head end of the elongated hole 101, the first valve core 51 and the second valve core 52 are both opened, and when the handle 23 is rotated to the end of the elongated hole 101, the first valve core 51 and the second valve core 52 are both closed. The two ends of the elongated hole 101 can also limit the rotation range of the switch member 2, so that when the switch member 2 rotates, it can accurately rotate to the open state or the closed state with the two valve cores.

[0032] The above-mentioned water outlet pipe 4 can adopt the same structure as the water inlet pipe 3. Correspondingly, the second valve core 52 also adopts the same structure as the first valve core 51. The connection structure between the second valve core 52 and the second connecting member 22 can also copy the connection structure between the first valve core 51 and the first connecting member 21.

[0033] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention specification and drawings under the utility model concept, or directly or indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
