Abstract
The invention discloses a thermo dual metal actuator with single-chip body structure and double actuating function, comprising a left chip body (2) and a right chip body (3) which are connected into a whole structure, wherein the left side of the left chip body (2) is provided with a left jump wing (1); the right side of the right chip body (3) is provided with a right jump wing (4), and at least one chip body of the left chip body and the right chip body is provided with a positioning hole (5). The thermo dual metal actuator adopts a double wing design, so that the actuator with the single chip body structure has double actuating function. A temperature sensing point is arranged on a middle connecting position between the left chip body and the right chip body, the consistency for temperature sensing is improved because of the same temperature sensing point, and the action consistency generated by the left jump wing and the right jump wing is improved, thereby the safety performance for a temperature sensing controller is improved.
Description
Technical field
The present invention relates to the heat-sensitive duplex metal actuator that uses in a kind of wireless liquid heater.
Background technology
Heat-sensitive duplex metal actuator of the prior art (as shown in Figure 3) generally comprises the lamellar body of a circle, one side of lamellar body is provided with the kick wing 6, the opposite side of lamellar body is provided with temperature-sensitive portion 7, the middle part of lamellar body is provided with pilot hole 5, owing to have only a kick wing, so existing heat-sensitive duplex metal actuator only has single actuation function.Existing wireless liquid heater generally is equipped with the heat-sensitive duplex metal actuator of two (or more than two) said structures with temp sensing controller, be divided into the both sides of temp sensing controller, rely on two heat-sensitive duplex metal actuators to experience well heater difference temperature respectively and produce action, thereby realize the temperature control action, this kind mode is because heat-sensitive duplex metal actuator temperature-sensitive point is different, can cause temperature contrast, thereby cause two differences on the heat-sensitive duplex metal actuator action speed, even the situation of a slice heat-sensitive duplex metal actuator action appears having only, there is potential safety hazard.
Summary of the invention
The heat-sensitive duplex metal actuator that technical matters to be solved by this invention provides a kind of monolithic body structure and has the dual activation function.
For solving the problems of the technologies described above, the present invention is by the following technical solutions: a kind of heat-sensitive duplex metal actuator, comprise left sheet and right sheet, left sheet is connected into a single integrated structure with right sheet, the left side of left sheet is provided with the left kick wing, the right side of right sheet is provided with the right kick wing, wherein has at least a lamellar body to be provided with pilot hole.
The invention has the beneficial effects as follows: because heat-sensitive duplex metal actuator is made up of be connected into a single integrated structure left sheet and right sheet, be respectively equipped with the left kick wing and the right kick wing on left sheet and the right sheet, when the actuator of being made up of be connected into a single integrated structure left sheet and right sheet is experienced overheated heater temperature generation deformation, the left side kick wing and the right kick wing all can produce kick, thereby make the actuator of monolithic body structure have the dual activation function; Heat-sensitive duplex metal actuator of the present invention adopts the double-vane design, the temperature-sensitive point is located at the junction, middle part between left sheet and the right sheet, has same temperature-sensitive point, and the temperature-sensitive consistance is strengthened, the left side kick wing and the right kick wing produce action consistency and improve, thereby improve the security performance of temp sensing controller.
The invention will be further described below in conjunction with the drawings and specific embodiments.
