DETAILED DESCRIPTION

[0058] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0059] The multi-key water distribution valve core according to the embodiments of the present application will be described below with reference to the drawings. Figures 1 to 20

[0060] According to the embodiments of the present application, a multi-key water distribution valve core is provided, which is suitable for being applied in shower, toilet, faucet and other bathroom equipment, and comprises a plurality of pressing shafts 1, a plurality of first elastic members 2, an emergency unlocking reset shaft 3, a second elastic member 4, a rotating buckle 5, a switching locking mechanism and an emergency unlocking mechanism. The first elastic member 2 and the second elastic member 4 can be springs. ​

[0061] Specifically, as shown in Figure 1 , a plurality of pressing shafts 1 are arranged corresponding to a plurality of first elastic members 2, and the first elastic members 2 are adapted to act on the pressing shafts 1 and make the pressing shafts 1 have a tendency of axial reset movement. An emergency unlocking reset shaft 3 is arranged corresponding to a second elastic member 4, and the second elastic member 4 is adapted to act on the emergency unlocking reset shaft 3 and make the emergency unlocking reset shaft 3 have a tendency of axial reset movement.

[0062] Referring to Figure 3 , Figure 17 and Figure 20 , the rotating buckle 5 can be disc-shaped, and the rotating buckle 5 has a central axis 504. The rotating buckle 5 includes an emergency unlocking reset hole 501 and a plurality of key holes 502. The emergency unlocking reset shaft 3 is slidably arranged in the emergency unlocking reset hole 501, and the plurality of key holes 502 are arranged corresponding to the plurality of pressing shafts 1, and the pressing shafts 1 are slidably arranged in the key holes 502.

[0063] A plurality of pressing shafts 1 and the rotating buckle 5 are respectively provided with a switching locking mechanism, as shown in Figure 5 and Figure 16 , the switching locking mechanism includes a first locking portion 6 and a second locking portion 7 abutting each other. The pressing shaft 1 is provided with the first locking portion 6, and the hole wall of the key hole 502 is provided with the second locking portion 7. At least one of the abutting positions of the first locking portion 6 and the second locking portion 7 is provided with an inclined abutting surface 8, and the first locking portion 6 and the second locking portion 7 are relatively slid by being pushed by the inclined abutting surface 8 and push the rotating buckle 5 to rotate in a first direction around the central axis 504 thereof. Preferably, the abutting positions of the first locking portion 6 and the second locking portion 7 are both provided with the inclined abutting surface 8.

[0064] Specifically, when the pressing shaft 1 is in an initial position, the first locking portion 6 is located above the second locking portion 7. As shown in Figure 4 , when the pressing shaft 1 is in a locked position, the first locking portion 6 is located below the second locking portion 7. Pressing one of the pressing shafts 1 in the initial position, the first locking portion 6 and the second locking portion 7 are relatively slid by being pushed by the inclined abutting surface 8, and the rotating buckle 5 is circumferentially rotated. When the first locking portion 6 is located below the second locking portion 7 and abuts against the second locking portion 7, the pressing shaft 1 is released, and the pressing shaft 1 is in the locked position. At the same time, with the rotation of the rotating buckle 5, the locking of the previous pressing shaft 1 in the locked position is released, and the previous pressing shaft 1 in the locked position is reset to the initial position under the action of the elastic force of the first elastic member 2. Therefore, pressing one of the pressing shafts 1 can open the corresponding waterway and close other waterways.

[0065] An emergency unlocking mechanism is arranged between the emergency unlocking reset shaft 3 and the rotating buckle 5, as shown in Figure 8 and Figure 16As shown, the emergency unlocking mechanism comprises the abutting bevel gear part 9 and the tooth groove 10. One of the emergency unlocking reset shaft 3 and the hole wall of the emergency unlocking reset hole 501 is provided with the bevel gear part 9, and the other is provided with the tooth groove 10. That is, the emergency unlocking reset shaft 3 is provided with the bevel gear part 9, and the hole wall of the emergency unlocking reset hole 501 is correspondingly provided with the tooth groove 10; or the hole wall of the emergency unlocking reset hole 501 is provided with the bevel gear part 9, and the emergency unlocking reset shaft 3 is correspondingly provided with the tooth groove 10. For example, in order to facilitate processing, the emergency unlocking reset shaft 3 is provided with the bevel gear part 9, and the hole wall of the emergency unlocking reset hole 501 is provided with the corresponding tooth groove 10. Specifically, the number of bevel gear parts 9 is multiple, and the multiple bevel gear parts 9 are uniformly distributed around the circumference of the pressing shaft 1, and the tooth groove 10 and the bevel gear part 9 correspond one by one.

[0066] As shown in Figure 8 and Figure 16 As shown, the abutting place of the bevel gear part 9 and the tooth groove 10 is provided with an arc abutting surface 11, the bevel gear part 9 and the tooth groove 10 are relatively slipped by the arc abutting surface 11 and push the rotating buckle 5 to rotate around the axis 504 in the second direction. Wherein, the first direction is opposite to the second direction, that is, if the first direction is counterclockwise, the second direction is clockwise; if the first direction is clockwise, the second direction is counterclockwise. When all the pressing shafts 1 are simultaneously pressed down due to unexpected situations and are all in the locked position, causing the linkage switching to fail, the emergency unlocking reset shaft 3 is pressed down, the bevel gear part 9 and the tooth groove 10 are relatively slipped by the arc abutting surface 11 and push the rotating buckle 5 to rotate reversely, and all the pressing shafts 1 can be simultaneously reset to the initial position, avoiding damage. Since no locking structure is arranged between the emergency unlocking reset shaft 3 and the rotating buckle 5, the emergency unlocking reset shaft 3 will not be locked.

[0067] In this way, the linkage between the multiple pressing shafts 1 and the rotating buckle 5 is realized by the switching locking mechanism, so that one of the pressing shafts 1 is pressed down to open the corresponding waterway and close other waterways, providing a more convenient operation mode and improving the user experience. And by pressing the emergency unlocking reset shaft 3, the rotating buckle 5 is pushed to rotate, so that the multiple pressing shafts 1 can be simultaneously reset, avoiding damage caused by accidental operation.

[0068] In some embodiments of the present application, as shown in Figure 17 As shown, the multiple key holes 502 are distributed around the circumference of the emergency unlocking reset hole 501. It should be noted that the number of key holes 502 can be determined according to actual design requirements, and each key hole 502 is uniformly distributed around the circumference of the emergency unlocking reset hole 501. In this way, the multiple pressing shafts 1 are arranged in a ring array around the emergency unlocking reset shaft 3, thereby making the structure compact and saving costs.

[0069] In some embodiments of the utility model, see Figures 9 to 11 As shown, the multi-key water distribution valve core further comprises a water distribution body 12, and the water distribution body 12 comprises a plurality of first mounting holes 1201 and a plurality of first water inlets 1203. Figure 3 As shown, the pressing shaft 1 is inserted into the first mounting hole 1201, the first mounting hole 1201 is a stepped through hole, and a first sealing ring 1202 is arranged between the small hole section 12011 of the first mounting hole 1201 and the pressing shaft 1 to prevent water leakage from the joint between the pressing shaft 1 and the small hole section 12011 and improve the sealing performance. Figure 5 As shown, a second annular groove 104 can be arranged on the pressing shaft 1, or as shown, Figure 10 A second annular groove is arranged on the hole wall of the small hole section 12011. Figure 3 As shown, the first sealing ring 1202 is embedded in the second annular groove 104.

[0070] As shown, Figure 9 And Figure 11 As shown, the plurality of first water inlets 1203 are arranged corresponding to the plurality of first mounting holes 1201, the first water inlets 1203 are in communication with the large hole sections 12012 of the first mounting holes 1201 to form branch water paths 1204. Figure 3 And Figure 6 As shown, the pressing shaft 1 protrudes and is provided with a plugging part 101 for closing the first water inlet 1203, and a second sealing ring 1205 is arranged between the plugging part 101 and the large hole section 12012 of the first mounting hole 1201 to prevent water leakage from the joint between the pressing shaft 1 and the large hole section 12012 and reliably open or close the branch water path 1204.

[0071] The number of second sealing rings 1205 can be two or more, and each second sealing ring 1205 is distributed along the axial direction of the pressing shaft 1. Need to be explained, as shown in the multi-key water distribution valve core, Figure 3 As shown, the upper and lower directions in the figure are the axial direction of the pressing shaft 1. Specifically, as shown, Figure 5 A first annular groove 103 can be arranged on the pressing shaft 1, or as shown, Figure 11 A first annular groove is arranged on the hole wall of the large hole section 12012. Figure 3 As shown, the second sealing ring 1205 is embedded in the first annular groove 103.

[0072] And as shown, Figure 6As shown, the water passing hole 102 is arranged in the blocking part 101, and the water passing hole 102 is suitable for making the water flow through the branch water path 1204 when the pressing shaft 1 drives the blocking part 101 to open the first water inlet 1203. Specifically, when the pressing shaft 1 is in the initial position, the blocking part 101 closes the first water inlet 1203, so that the branch water path 1204 is in the closed state. When the pressing shaft 1 is in the locked position, the blocking part 101 is lowered to open the first water inlet 1203, at this time, the blocking part 101 divides the large hole section 12012 of the first mounting hole 1201 into two upper and lower chambers, and the two upper and lower chambers are communicated through the water passing hole 102 in the blocking part 101, so that the branch water path 1204 is in the open state.

[0073] In this way, through the cooperation of the plurality of pressing shafts 1 and the water distribution body 12, the opening or closing of the plurality of branch water paths 1204 can be realized, so that the use requirement of the multi-water path application environment can be met.

[0074] In some embodiments of the utility model, as shown in Figure 4 The multi-key water distribution valve core further includes a cover body 13, and the cover body 13 is arranged on the side of the water distribution body 12 away from the blocking part 101. Specifically, as shown in Figure 18 The cover body 13 is provided with a plurality of sixth mounting holes 1303, as shown in Figure 10 The water distribution body 12 is correspondingly provided with a plurality of tenth mounting holes 1209, and the cover body 13 is fixed on the water distribution body 12 by sequentially penetrating the fasteners such as screws through each opposite sixth mounting hole 1303 and tenth mounting hole 1209. Moreover, the cover body 13 is also provided with a plurality of second mounting holes 1301 for the plurality of pressing shafts 1 to pass through, so that the pressing shafts 1 can extend into the water distribution body 12.

[0075] As shown in Figure 4 The rotating buckle 5 is rotationally connected to the side of the cover body 13 away from the water distribution body 12, and in order to reduce the friction between the two, the bottom surface of the rotating buckle 5 is provided with an annular convex rib 503, and the annular convex rib 503 abuts against the cover body 13. In addition, as shown in Figure 18 The sixth mounting hole 1303 is a counterbore, so as to prevent the screw cap from protruding out of the surface of the cover body 13 and affecting the flexible rotation of the rotating buckle 5. As shown in Figure 19 The cover body 13 is also provided with an annular flange 1304. As shown in Figure 4 The annular flange 1304 extends into the water distribution body 12, so that the cover body 13 is closely matched with the water distribution body 12.

[0076] In this way, the water distribution body 12 is covered by the cover body 13, which improves the reliability of the action of the pressing shaft 1, and facilitates the arrangement and installation of the rotating buckle 5, so that the rotating buckle 5 can work reliably.
