DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0029] Please refer to Figure 1-5 ;

[0030] The utility model aims to provide a rotary water supply switch, which reduces the number of action steps and is more convenient to use; specifically, it comprises a fixed seat 11 and a water outlet 2, wherein the fixed seat 11 can be a base placed on a desktop, or can be used as one of the components in a water boiling device, which is not limited here, and the water outlet 2 extends out of the fixed seat 11, and can be used to control the switch by rotating the water outlet 2. More specifically, a water guide channel 12 and a trigger switch 3 are provided in the fixed seat 11, wherein the water guide channel 12 can be a connecting pipe, or can be a channel integrally formed with the fixed seat 11, and one end of the water guide channel 12 is connected to a water pump or a device with a water supply function through a connecting piece. The other end is rotatably connected to the end of the water outlet head 2. In this embodiment, the water guide channel 12 is preferably made in an integral manner with the fixed seat 11, which can improve the sealing performance. A corresponding sealing structure should be provided between the water outlet head 2 and the fixed seat 11 to prevent water leakage. For example, an annular sealing ring is clamped at the end of the water outlet head 2, and a groove is provided on the side of the water guide channel 12. The sealing ring is clamped into the groove, which can achieve a sealing effect and the purpose of relative rotation between the water outlet head 2 and the fixed seat 11. A retaining spring can also be used to limit the longitudinal movement of the water outlet head 2 to prevent the water outlet head 2 from being pulled out of the fixed seat 11. Of course, this is only one implementation method and should not be used as a limitation on the scope of protection.

[0031] In addition, a trigger part 4 is fixedly provided at one end of the water outlet head 2. Preferably, the trigger part 4 is located in the fixing seat 11, and the upper surface of the trigger part 4 is in contact with the inner wall of the fixing seat 11. The water outlet head 2 is placed and pulled out from the fixing seat 11 by using the trigger part 4. In addition, the longitudinal position of the water outlet head 2 in the fixing seat 11 can be limited by combining the sealing ring and the card slot. In the initial state, the trigger part 4 cannot turn on the trigger switch 3. When the water outlet head 2 needs to be rotated to a certain angle, the trigger part 4 can be in contact with the trigger switch 3. At this time, the trigger switch 3 is turned on, and the water supply device or the water pump starts to work, and water enters from one end of the water guide channel 12, and then enters into the water outlet head 2 from the other end, and finally flows out from the water outlet head 2. After reaching a certain amount of water, the water outlet head 2 is reset or rotated to other angles to separate the trigger part 4 from the trigger switch 3, so that the electrical signal can be disconnected, and the water pump or the water supply device stops running.

[0032] It should be noted that the trigger switch 3 should be connected to the controller to determine whether to supply water by turning on and off the electrical signal. The controller can be a controller currently built into the water supply device on the market, which will not be described in detail here.

[0033] The water filling method on the market is to click on the touch panel, and each manufacturer has a slightly different operation method for the water filling click, so it is at a loss for users who operate it for the first time. These water filling kettles are often used in places where people drink morning tea, and the situation where users cannot operate them is particularly obvious. The present application adopts the method of rotating the water outlet head 2 to realize the switch, without the need for cumbersome touch operation, simplifies the operation steps of water filling, and provides a better user experience.

[0034] Furthermore, in order to avoid the problem that the user forgets to reset the water head and the kettle continues to discharge water, causing it to overflow, the output time can be limited in the controller to solve this problem.

[0035] The first embodiment of the utility model regarding the trigger part 4 and the trigger switch 3;

[0036] Specifically, the trigger part 4 is a fixed block 41 with a protrusion on one side, and the trigger switch 3 is a micro switch 31. When the water outlet head 2 rotates a certain angle, the protrusion on one side of the fixed block 41 will contact the micro switch 31 to achieve continuous conduction. When the water outlet head 2 rotates to reset, the protrusion separates from the micro switch 31, and the micro switch 31 is in an off state.

[0037] Furthermore, the triggering portion 4 is elliptical, that is, the water outlet head 2 can be rotated forward or reversely to trigger the micro switch 31, and the entire device can be placed in any position.

[0038] The second embodiment of the utility model is about the trigger part 4 and the trigger switch 3;

[0039] Specifically, the trigger part 4 includes a conductive connecting part 45 (not shown in the figure), the outer periphery of the conductive connecting part 45 is sleeved with a shaft sleeve 421, and the side of the shaft sleeve 421 is provided with two through holes 422, wherein the conductive connecting part 45 can be a coil, and the trigger switch 3 includes two conductive spring pieces 43, and the inner side of the conductive spring pieces 43 is provided with a conductive protrusion 44; when the water outlet head 2 rotates a certain angle, the two conductive protrusions 44 respectively enter the two through holes 422 and contact the coil, and the two conductive protrusions 44 can be turned on through the coil, that is, the two conductive spring pieces 43 start to conduct electricity, and the switch is in the on state; when the water outlet head 2 rotates and resets, the two conductive protrusions 44 slide out of the through holes 422 and separate from the conductive connecting part 45, and the switch is in the off state.

[0040] Regarding the variant implementation of the second embodiment, the trigger part 4 includes a conductive connection part 45, and a conductive protrusion 2 423 is provided on the side of the conductive connection part 45. The trigger switch 3 includes two conductive springs 43. In one implementation, the number of the conductive protrusion 2 423 is one. At this time, one of the conductive springs 43 is always in contact with the conductive connection part 45, while the other conductive spring 43 is not in contact with the conductive connection part 45. When the water outlet head 2 rotates a certain angle, the conductive protrusion 2 423 contacts the other conductive spring 43. At this time, the two conductive springs 43 are in a conductive state;

[0041] In another embodiment, the number of the second conductive protrusions 423 is two. In the initial state, the two conductive springs 43 are not in contact with the conductive connecting portion 45. Preferably, the two conductive springs 43 are arc-shaped. When the water outlet head 2 rotates a certain angle, the two second conductive protrusions 423 are in contact with the two conductive springs 43 respectively. At this time, the two conductive springs 43 are in a conductive state.

[0042] Furthermore, a sleeve 421 (not shown) is fixedly disposed on the outer periphery of the conductive connection portion 45 , and the second conductive protrusion 423 extends out of the sleeve 421 ;

[0043] When the water outlet head 2 rotates a certain angle, the two conductive protrusions 423 contact the two conductive spring sheets 43 respectively, that is, the two conductive spring sheets 43 start to conduct electricity, and the switch is in the on state; when the water outlet head 2 rotates to reset, the two conductive protrusions 423 separate from the conductive spring sheets 43, and the switch is in the off state.

[0044] It should be noted that, based on the first embodiment and the second embodiment, the trigger part 4 is located outside the water guide channel 12, or below the trigger part 4, and a sealing structure is provided at the end of the water outlet head 2 to prevent water seepage.

[0045] In an embodiment of the utility model, a controller is also included, which is electrically connected to the delay module and the trigger switch 3 respectively. That is, after the water head 2 is rotated to a certain angle, the trigger switch 3 is in an on state, and at the same time the extension module starts to work, for example, for two seconds. After two seconds, the water pump or the water supply device starts to work. This can avoid accidental touch by the user and reserve some time to reset the water head 2.

[0046] Further, refer to Figure 7 The contact end of the conductive spring piece 43 is designed in an arc shape, and the arc is concave toward the conductive protrusion 423, which greatly improves the service life of the component.

[0047] Based on all the above implementations, refer to Figure 6If the water outlet head 2 is connected to the trigger part 4 in a split-type connection, a positioning groove 46 is provided on the inner side of the trigger part 4, and a limiting protrusion 21 is provided on the outer side of the water outlet head 2. The limiting protrusion 21 is engaged with the positioning groove 46. Such a structure can prevent the trigger part 4 from deflecting when the water outlet head 2 is rotated.
