Examples

With reference to fig. 1 to 4, the present embodiment provides a novel switch structure, which is suitable for controlling the valve core 10 of the water outlet device to be opened and closed by toggling in a manner of pressing and switching. The switch structure includes a main body 1, a mount 2 disposed in the main body 1, and a key 3 exposed at one side of the main body 1. The key 3 is hinged on the mounting base 2 and is movably switched between a tilting state and a tilting state after being controlled by the pressing operation of a user. The key 3 is abutted to the toggle part 11 of the valve core 10 through a bushing 4 with a taper, and under the cooperation of the bushing 4 and the toggle part 11, when the toggle part 11 is at the closing position, the taper is enabled to move to the first deflection position in an adaptive manner so as to provide acting force for one tilting state of the key 3. When the toggle part 11 is in the open position, the taper is enabled to move to the second deflection position adaptively so as to provide acting force for the other tilting state of the keys 3, and further the travel of the keys 3 between the moving positions is locked.

In the above, through the bush 4 configured between the key 3 and the valve core 10, it cooperates in the toggle part 11 of the valve core 10 in the taper runout process, thereby only through the toggle part 11 toggling when the valve core 10 is opened and closed, the reaction (for the pressing action of the user on the key) to drive the taper runout of the bush 4 to limit the key 3 at the moving position thereof, and a simpler and faster stroke locking mode is realized.

In addition, the key is in a tilting state in the opening and closing operation process, so that the visual sense of the key 3 is very strong no matter the key is in any opening and closing position, a person can understand the operation mode of the key 3 at a glance, and the conditions of operation confusion and the like are avoided. Moreover, when the key 3 is pressed, the key is turned into a sunken state from a tilting state, so that the operation hand feeling of a person is better, and the occurrence of excessive pressing is greatly reduced.

Particularly, the valve core 10 is switched back and forth between the upward tilting state and the downward tilting state corresponding to the key 3 in two states of being opened and closed by toggling, so that the operability of the whole switching process is excellent. The tilting state of the key 3 moves to a deflection position corresponding to the taper of the bush 4, and then the position switching of the toggle part 11 linked with the bush 4 is triggered, so that whether the valve core 10 discharges water or not is controlled. Similarly, the toggle part 11 acts on the stroke locking of the key 3 in a toggle action reaction at the valve core 10, the structure is simpler, the internal transmission matching is suitable for simplification, the use of a user is met, and the market popularization and application are facilitated.

Obviously, the novel switch structure is adapted to a valve core 10 structure driven by an existing toggle part 11 (such as a toggle lever), and the valve core 10 structure is controlled by an external force to toggle through the toggle lever arranged on the end part side thereof, and realizes water outlet of a pipeline corresponding to opening and closing of a water outlet of a controller. This is the prior art and will not be described herein. In this embodiment, when the toggle portion 11 is flush with the valve element 10 (the toggle portion 11 is at the initial position), the valve element 10 is controlled to be in the closed state, and at this time, the water outlet is closed and the pipeline does not discharge water. When the toggle part 11 is controlled by external force to tilt with the valve core 10 structure and keep at this position (the toggle part 11 is at the open position), the valve core 10 is controlled to be in the open state, at this time, the water outlet is opened and the pipeline water is supplied to the user end.

As shown in fig. 1, 3 and 4, in one embodiment, the bushing 4 is configured as a frustum structure, and the bottom side of the frustum structure is nested in the dial portion 11, and the top side thereof is movably clamped to the key 3. Thus, the bush 4 is configured such that one end is fixedly arranged on the toggle part 11 and the other end is movably arranged on the key 3, thereby facilitating the interaction between the structural members to transmit the torque. Specifically, the back surface of the key 3 is provided with a bayonet cavity adapted to the top end side of the frustum structure, and the edge of the bayonet cavity abuts against the inclined periphery side of the frustum structure. Furthermore, the cavity edge of the clamping cavity is in butt fit with the inclined peripheral side of the periphery of the frustum structure, so that the lining 4 is flexibly matched and jointed between the key 3 and the valve core 10 on the back of the key 3, and a quick and efficient transmission mode is achieved.

After the key 3 is in the upward tilting state or the downward tilting state, the bayonet cavity of the key can be triggered to lift or reset the frustum structure, the taper of the bushing 4 is switched to one of the deflection positions, and the toggle part 11 is enabled to be linked to the closing position or the opening position. Wherein, a deflection position is selected and arranged to be flush with the toggle part 11 at the closing position and the valve core 10. In this embodiment, when the key 3 is in the downward tilting state, the taper of the bushing 4 corresponds to the first deflection position, and at this time, the toggle portion 11 and the valve element 10 are on the same horizontal plane. When the key 3 is switched to the upwarp state, the taper of the bushing 4 is correspondingly controlled to move to the second deflection position, and at this time, the toggle part 11 inclines upwards relative to the valve core 10, is adapted to the upwarp state of the key 3 and reacts on the key 3 through the toggle part 11 to limit the key 3 at the upwarp position.

Specifically, the direction of the taper is inclined downward toward the key 3 side. And the cavity edge of the clamping cavity is clamped at the middle position of the inclined peripheral side. Thereby, it is ensured that the head of the bush 4 (the part located in the bayonet cavity) can be arranged in the bayonet cavity of the key 3 in a ball-and-socket like manner.

As shown in fig. 3 and 4, in an embodiment, the key 3 is a triangle, and an end surface of the key facing to the outside of the main body 1 is defined as a front surface, and two corners of the front surface are configured as an arc-shaped protruding raised structure.

Thereby, the operability and visual intuition of the key 3 are further improved.

Wherein, the bush 4 is fixedly connected with the toggle part 11 through a fastening piece 7 which is arranged on the bush 4 in a penetrating way. It should be noted that, in the present embodiment, the mount 2 is formed on the outer gland 20, and the gland 20 is removably disposed in the main body 1 and defines the valve cartridge 10 at the mounting position. The valve core 10 is assembled in the main body 1 in such a way that the valve core 10 is firmly fixed at a desired position by screwing or other dismounting and fastening forms of the gland 20 in the main body 1 after the valve core 10 is arranged at the installation position. The installation seat 2 and the gland 20 are arranged integrally, so that the installation seat 2 at least forms part of the gland 20 structure, the hinge arrangement of the key 3 on the installation seat 2 is realized after the pin 6 is arranged at the hinge part in a penetrating manner, the key 3 is limited to rotate only along the stroke paths of two tilting states of the key, the tilting states and the tilting states are matched with the inner wall of the main body 1 in opposite positions, and the stability of stroke locking is further improved. In addition, the bush 4 is locked by using a fastening member 7 such as a screw, and the gland 20 is fixed to the main body 1, thereby ensuring a more compact fit between the internal structures.

As shown in fig. 1 and fig. 2, the present embodiment further provides a water outlet device, which includes a water outlet body 30, a gland 20, a valve core 10 disposed on the water outlet body 30, and a novel switch structure for linking with the valve core 10. An upper cover 40 is disposed between the valve body 10 and the gland 20. With such an arrangement, the respective structures inside the water outlet device can be assembled together more compactly and stably. The water outlet device in the present case can be, but is not limited to, various faucets, showers, etc.

The main body 1 is integrally formed at a lateral extending position of the water outlet body 30, the main body 1 is provided with a plurality of keys 3 and valve cores 10 matched with the keys in parallel, and the valve cores 10 corresponding to the tilting states of different keys 3 are different in opening and closing. Therefore, the main body 1 integrally formed on the water outlet body 30 forms a part of the structure of the whole water outlet device, which is beneficial to integral manufacture and convenient for assembly and matching.

Particularly, the side surface of the main body 1 can be provided with a plurality of keys 3 and valve core 10 structures thereof, so that a multi-directional and multi-selection water outlet control mode is realized, and in order to avoid the situation that the rising state of the keys 3 and the water outlet opening and closing are uniform and easily cause the user to touch by mistake, the rising state and the opening and closing state of the adjacent keys 3 are completely opposite, for example, the rising state of one key 3 corresponds to the opening of the control valve core 10, the falling state of the other key 3 corresponds to the opening of the control valve core 10, and the pressing operation mode of the key is favorably and quickly distinguished when the user uses the key.
