Description

Technical Field

[0001] The invention relates to a switching mechanism in the field of bathrooms, in particular to a linkage switching mechanism and a shower head using the mechanism. Background Art

[0002] Existing handle showers generally have more than three functional water sprays, and the switching methods are mainly rotating cover type and button type. Among them, the button type handle shower has only one button, and each time it is pressed, a water spray is switched. The switching mechanism is inside the shower, and it is impossible to know which water spray is currently being produced, which brings inconvenience to the user. Summary of the invention

[0003] The technical problem to be solved by the present invention is aimed at the deficiencies of the above-mentioned prior art. A linkage switching mechanism and a shower head using the mechanism are provided. The linkage switching mechanism and the shower head using the mechanism are provided with three interacting switches. When any one of the switches is pressed, the corresponding water function is turned on, and the other switches automatically turn off the corresponding functions. Therefore, the current shower function can be quickly known by observing the pressing state of the switch, and the operation is intuitive and convenient.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a linkage switching mechanism, characterized in that it includes: a base, a switching cavity, a water inlet pipe, a side hole A, a side hole B, a side hole C, a water outlet hole A, a water outlet hole B, and a water outlet hole C are arranged, the water inlet pipe, the side hole A, the side hole B, and the side hole C are respectively connected to the switching cavity, wherein the side hole A, the side hole B, and the side hole C are radially arranged with the central axis of the switching cavity as the axis array, the water outlet hole A is connected to the side hole A, the water outlet hole B is connected to the side hole B, and the water outlet hole C is connected to the side hole C;

[0005] Push rod assemblies are provided in 3 groups, which are respectively and movably provided in the side holes A, B and C, and move between the open position and the closed position, and are linked to each other, that is, when the push rod assembly in one of the side holes is in the open position, the push rod assemblies in the other two side holes are in the closed position due to the linkage effect;

[0006] In the open position, the push rod assembly opens the water inlet of the side hole where it is located; in the closed position, the push rod assembly blocks the water inlet of the side hole where it is located.

[0007] The present invention can open the corresponding waterway by pressing the push rod assembly, while the other two waterways are automatically closed. Therefore, only one action is needed to quickly open one waterway and close the other waterways. The operation is convenient and simple. This linkage switching mechanism is particularly suitable for shower controllers. The shower in a general shower room includes: a top spray, a handle shower, and a faucet. Usually, we use the top spray alone, or the handle shower alone, or the faucet alone. Therefore, the linkage switching mechanism of the present invention is particularly suitable for use in such occasions. We can close one waterway and open another waterway at the same time by triggering a switch. At the same time, the present invention can also be applied to a handle shower, because the current handle shower generally has three water spray functions. By setting the linkage switching mechanism in the handle shower, we can quickly know the current function by observing the pressing state of the switch, and the operation is intuitive and convenient.

[0008] Optionally, the push rod assembly includes a push block and a push rod, wherein: the push block is movably arranged in the switching cavity, and the switching cavity is provided with a guide groove cooperating with the push block, the push block slides under the guiding action of the guide groove, the push block is provided with a sink groove at one end facing the side hole, a sealing gasket is fixedly provided on the sink groove, a side inclined surface is provided at the end facing away from the side hole, and the side inclined surface is a symmetrical inclined surface with an angle of 120°; the push rod is arranged axially along the side hole, one end of the push rod is fixed to the push block, and the other end extends out of the side hole opening.

[0009] When a push rod is pushed, the push block at its end moves toward the center. Due to the interaction between the side slopes of each push block, the other two push blocks will be pushed until they reach the position of blocking the water inlet of the side hole. Due to the effect of water pressure, the push block will remain in a blocked state, while the water pressure on both sides of the push block in the open position remains unchanged, so it can maintain the open state.

[0010] Optionally, it also includes a fixing part and a sealing ring, which are arranged in 3 groups. The fixing part is fixedly arranged at the opening end of the side hole, a through hole is arranged in the middle of the fixing part, and the through hole is coaxially clearance-matched with the push rod. The sealing ring is fixedly arranged on the fixing part and movably seals with the push rod.

[0011] Optionally, the push rod assembly further includes a spring, the spring is coaxially arranged with the push rod, a retaining ring is arranged in the middle of the push rod, a supporting ring is arranged at the water inlet end of the side hole, one end of the spring abuts against the retaining ring, and the other end abuts against the supporting ring. By arranging the spring, the functional stability can be improved, that is, the sealing can be better under low water pressure conditions.

[0012] Optionally, a fixing column is provided on the fixing member, and a fixing hole cooperating with the fixing column is correspondingly provided on the base.

[0013] Optionally, a linkage ring is further included, and a linkage column is provided on the lower end surface of the push block, and the linkage column is inserted into the linkage ring. The linkage ring is provided to improve the stability of the structure, because the diameter of the linkage ring is small, and when the two sets of push rod assemblies are in the closed position, the linkage ring will be pulled in one direction, and the remaining set of push rod assemblies will be pulled to the open position.

[0041] The following is a specific description with reference to embodiments.

[0042] Embodiment 1:

[0043] like Figures 1 to 12 As shown, a linkage switching mechanism of the present invention and a shower head using the same are characterized by comprising: a base 200, a switching chamber 210, a water inlet pipe 220, a side hole A211, a side hole B212, a side hole C213, a water outlet hole A214, a water outlet hole B215, and a water outlet hole C216 are provided, wherein the water inlet pipe 220, the side hole A211, the side hole B212, and the side hole C213 are respectively connected to the switching chamber 210, wherein the side holes A211, the side holes B212, and the side holes C213 are radially arranged with the central axis of the switching chamber 210 as the axis center array, the water outlet hole A214 is connected to the side hole A211, the water outlet hole B215 is connected to the side hole B212, and the water outlet hole C216 is connected to the side hole C213;

[0044] Push rod assemblies are provided in 3 groups, which are respectively and movably provided in the side hole A211, the side hole B212 and the side hole C213, and move between the open position and the closed position, and are linked with each other, that is, when the push rod assembly in one of the side holes is in the open position, the push rod assemblies in the other two side holes are in the closed position due to the linkage effect;

[0045] In the open position, the push rod assembly opens the water inlet of the side hole where it is located; in the closed position, the push rod assembly blocks the water inlet of the side hole where it is located.

[0046] The present invention can open the corresponding waterway by pressing the push rod assembly, while the other two waterways are automatically closed. Therefore, only one action is needed to quickly open one waterway and close the other waterways. The operation is convenient and simple. This linkage switching mechanism is particularly suitable for shower controllers. The shower in a general shower room includes: a top spray, a handle 120 shower head, and a faucet. Usually, we use the top spray alone, or the handle 120 shower head alone, or the faucet alone. Therefore, the linkage switching mechanism of the present invention is particularly suitable for use in such occasions. We can close one waterway and open another waterway at the same time by triggering a switch. At the same time, the present invention can also be applied to the handle 120 shower head, because the current handle 120 shower head generally has three water spray functions. By setting the linkage switching mechanism in the handle 120 shower head, we can quickly know the current function by observing the pressing state of the switch, and the operation is intuitive and convenient.

[0048] When a push rod 310 is pushed, the push block 320 at its end moves toward the center. Due to the interaction between the side slopes 322 of each push block 320, the other two push blocks 320 will be pushed until they reach the position of blocking the water inlet of the side hole, and due to the effect of water pressure, the push block 320 will maintain a blocked state, while the water pressure on both sides of the push block 320 in the open position remains unchanged, so it can maintain an open state.

[0049] In this embodiment, it also includes a fixing member 330 and a sealing ring 350, which are arranged in three groups. The fixing member 330 is fixedly arranged at the open end of the side hole.
