[0033] The utility model provides an actuator.

[0034] See also Figures 1 to 2 In one embodiment of the present invention, the actuator comprises:

[0035] A first housing 10 , on which a support base 40 is slidably provided;

[0036] a second housing 50 , the second housing 50 being disposed within the first housing 10 and abutting against the support base 40 ;

[0037] Among them, the second shell 50 includes a heating part, a temperature-changing elastic part 53 and a trigger part 51. The heating part is arranged in the second shell 50, and the heating part wraps the temperature-changing elastic part 53 and the trigger part 51. The temperature-changing elastic part 53 and the trigger part 51 are abutted against each other. The trigger part 51 partially passes through the second shell 50 and abuts against the first shell 10.

[0038] It should be noted that if Figure 2 and Figure 3 As shown, the heating part is wrapped around the temperature-variable elastic part 53 and the trigger part 41 . The heating part generates heat as needed and evenly transfers the heat to the temperature-variable elastic part 53 , so that the temperature-variable elastic part 53 deforms to drive the trigger part 51 to move.

[0039] It can be understood that the temperature-variable elastic portion 53 is a temperature-variable spring, and the temperature-variable spring is deformed by heat to control the movement of the trigger member 51 .

[0040] It should be noted that the actuator is mounted on the valve, and the ejector pin of the valve abuts against the support seat 40 .

[0041] It can be understood that the temperature-variable elastic part 53 is deformed by heat, causing the trigger member 51 to move, thereby driving the second shell 50 to move, so that there is a gap between the second shell 50 and the inner wall of the first shell 10. At this time, the valve ejector pin moves and drives the support seat 40 to move, so as to control the opening of the valve.

[0042] It can be understood that when the temperature-variable elastic part 53 is no longer heated, the temperature-variable elastic part 53 is reset, causing the trigger member 51 to move and reset, thereby causing the second shell 50 to adhere to the inner wall of the first shell 10. At this time, there is no longer any space in the first shell 10 for the support seat 40 to move, and the second shell 50 presses the support seat 40 to reset, thereby driving the valve pin to reset, thereby achieving the closure of the valve.

[0043] like Figures 2 to 6 As shown, the trigger member 51 is a rod, which is disposed in the second shell 50 and abuts against the first shell 10 .

[0044] It is understandable that when the trigger member 51 is completely retracted into the second shell 50 , the second shell 50 contacts the inner wall of the first shell 10 , limiting the movement of the support seat 40 within the first shell 10 .

[0045] It can be understood that when the trigger member 51 partially extends out of the second shell 50 and abuts against the inner wall of the first shell 10, there is a gap between the second shell 50 and the inner wall of the first shell 10, which provides a travel space for the movement of the support seat 40, making it convenient for the valve ejector pin to move and push the support seat 40 to move.

[0046] It should be noted that in order to prevent the trigger member 51 from moving and detaching from the second shell 50, the trigger member 51 is T-shaped, part of the trigger member 51 is passed through the second shell 50, and part of the trigger member 51 is restricted in the second shell 50 to ensure the stability of the movement of the trigger member 51.

[0047] The technical solution of the present invention is to arrange the temperature-variable elastic part 53 in the heating part so that the heating part is wrapped in the temperature-variable elastic part 53, thereby ensuring that the temperature-variable elastic part 53 is heated evenly and stably deformed, and drives the trigger part 51 to move, thereby facilitating the movement control of the valve top to the support seat 40, thereby realizing the opening and closing control of the valve, and the stable deformation of the temperature-variable elastic part 53 ensures the stability of the movement stroke of the trigger part and extends the service life of the actuator.

[0048] In one embodiment, a telescopic space 55 is provided in the heating portion, the temperature-variable elastic portion 53 and the triggering member 51 are both provided in the telescopic space 55 , and the temperature-variable elastic portion 53 partially abuts against the inner wall of the telescopic space 55 and is partially connected to the triggering member 51 .

[0049] like Figures 5 and 6 As shown, the heat generating portion generates heat, causing the temperature-variable elastic portion 53 to deform due to the heat, and the existence of the telescopic space 55 provides space for the deformation of the temperature-variable elastic portion 53 .

[0050] It can be understood that the telescopic space 55 is used to accommodate the temperature-changing elastic part 53 and the trigger part 51, and the heating part is wrapped in the temperature-changing elastic part 53 and the trigger part 51. Due to the existence of the telescopic space 55, the temperature-changing elastic part 53 can be deformed under the wrapping of the heating part, thereby ensuring the stability of the deformation of the temperature-changing elastic part 53.

[0051] It can be understood that the temperature-variable elastic part 53 is connected to the trigger part 51, and when the temperature-variable elastic part 53 is deformed, it drives the trigger part 51 to move in the telescopic space 55, thereby realizing the gap adjustment between the first shell 10 and the second shell 50, so as to provide a stroke for the movement of the support seat 40.

[0052] In one embodiment, the heating part includes an inner shell 56 and a copper sleeve 54, the copper sleeve 54 is arranged in the inner shell 56, and the telescopic space 55 is arranged in the copper sleeve 54, the copper sleeve 54 wraps the temperature-changing elastic part 53 and the trigger part 51, and the inner shell 56 is slidably arranged in the first shell 10 and abuts against the support seat 40.

[0053] In order to ensure the stability of heat transfer, the copper sleeve 54 is arranged in the inner shell 56 so that the copper sleeve 54 wraps the temperature-changing elastic part 53, which facilitates the uniform and rapid transfer of temperature to the temperature-changing elastic part 53, thereby ensuring the uniformity of temperature transfer and the timeliness of the response of the temperature-changing elastic part 53.

[0054] It can be understood that the telescopic space 55 is provided in the copper sleeve 54, and the copper sleeve 54 accommodates the temperature-variable elastic part 53. The copper sleeve 54 transfers the heat of the inner shell 56 to deform the temperature-variable elastic part 53, and at the same time, the deformation of the temperature-variable elastic part 53 drives the trigger part 51 to move, thereby ensuring the opening and closing of the control valve.

[0055] In one embodiment, an elastic member 30 is sleeved on the inner shell 56 , and a portion of the elastic member 30 abuts against the inner wall of the first shell 10 .

[0056] In order to enable the second shell 50 to move relative to the first shell 10 after the trigger member 51 moves, and to change the moving range of the support seat 40 in the first shell 10, the elastic member 30 is provided on the second shell 50, and the elastic member 30 abuts against the inner wall of the first shell 10.

[0057] like Figure 2 and Figure 3 As shown, the elastic member 30 is sleeved on the inner shell 56 , and one end of the elastic member 30 away from the support seat 40 abuts against the inner wall of the first shell 10 .

[0058] It can be understood that when the temperature-variable elastic part 53 is deformed by heat, it drives the trigger member 51 to move, that is, the trigger member 51 partially extends out of the second shell 50 and abuts against the first shell 10. At this time, the second shell 50 moves relative to the first shell 10, and the elastic member 30 is compressed.

[0059] It can be understood that when the temperature-variable elastic part 53 is deformed and reset, it drives the trigger member 51 to reset and the trigger member 51 moves into the telescopic space 55. At this time, the elastic member 30 releases the elastic force and causes the second shell 50 to move and abut against the inner wall of the first shell 10. When the second shell 50 moves, it drives the support seat 40 to move, thereby causing the valve ejector pin to move, thereby closing the valve.

[0060] It can be understood that the elastic member 30 is provided to assist the movement of the second shell 50, to prevent the second shell 50 from being restricted in the first shell 10 due to factors such as friction, to ensure the driven movement of the inner shell 56 during the movement of the trigger member 51, to control the movement of the valve ejector pin, and to realize the control of the opening and closing of the valve.

[0061] It should be noted that the elastic member 30 is a spring, and the elastic member 30 is less affected by heat, so as to reduce the stroke error.

[0062] In one embodiment, a receiving space 57 is defined in the inner shell 56 , the copper sleeve 54 is disposed in the receiving space 57 , a heating portion 52 is defined in the receiving space 57 , and the heating portion 52 is in contact with the copper sleeve 54 .

[0063] like Figures 4 to 6 As shown, part of the trigger member 51 is passed through the copper sleeve 54 and the inner shell 56, and abuts against the inner wall of the first shell 10, so as to facilitate synchronous movement during the deformation of the temperature-variable elastic part 53 and drive the inner shell 56 to move in the first shell 10.

[0064] It can be understood that the accommodating space 57 is used to accommodate the copper sleeve 54, and the heating part 52 is arranged in the accommodating space 57. The heating part 52 is in close contact with the copper sleeve 54. The heat of the heating part 52 is transferred to the copper sleeve 54 and is evenly transferred to the temperature-changing elastic part 53 by the copper sleeve 54, ensuring that the temperature-changing elastic part 53 is uniformly deformed, so that the deformation effect is guaranteed, and thus the stability of the stroke of the trigger member 51 is ensured.

[0065] It should be noted that the heating portion 52 is a heat source such as a heating plate that can provide stable heat to the temperature-variable elastic portion 53 .

[0066] In one embodiment, the heating portion 52 is disposed on a first side surface of the copper sleeve 54 , and the first side surface is located on a side of the temperature-variable elastic portion 53 facing away from the triggering member 51 .

[0067] like Figures 5 and 6 As shown, the heating portion 52 , the temperature-variable elastic portion 53 and the triggering member 51 are arranged on the same straight line.

[0068] It can be understood that the heating part 52 is arranged on the first side of the copper sleeve 54 to ensure that heat can be transferred to the temperature-changing elastic part 53 with maximum efficiency under the transfer of the copper sleeve 54, ensuring that the temperature-changing elastic part 53 is heated evenly and efficiently, and ensuring the response efficiency of the trigger member 51.

[0069] It should be noted that the copper sleeve 54 is wrapped around the temperature-variable elastic part 53 , so that the heated copper sleeve 54 evenly transfers heat to the entire temperature-variable elastic part 53 , so that the copper sleeve 54 can deform stably.

[0070] It can be understood that the heating part 52 is arranged on the side of the temperature-changing elastic part 53 away from the trigger part 51, so that the heating part 52 can be quickly and evenly heated under the heat transfer of the copper sleeve 54 when working, and stably deform, thereby ensuring the stability of the moving stroke of the trigger part 51, ensuring the stability and accuracy of its control, and ensuring the service life.

[0071] In one embodiment, the heating portion 52 is disposed on a second side surface of the copper sleeve 54 , which is parallel to the moving plane of the trigger member 51 , and the copper sleeve 54 is used to achieve uniform heating of the temperature-variable elastic portion 53 .

[0072] It should be noted that a wiring harness 20 is passed through the first shell 10 and the second shell 50 , and the wiring harness 20 is connected to the heating element 52 to provide energy for the heating element 52 to generate heat.

[0073] In one embodiment, the first shell 10 includes a first shell 11 and a second shell 12, the second shell 12 is inserted into the first shell 11, the first shell 11 and the second shell 12 together form a moving space, the second shell 50 is slidably arranged in the moving space, the support seat 40 is slidably arranged in the second shell 12, the support seat 40 passes through the second shell 12, and abuts against the second shell 50.

[0074] It can be understood that the moving space formed by the first shell 11 and the second shell 12 provides space for the movement of the second shell 50 .

[0075] It can be understood that the support seat 40 is partially penetrated by the second outer shell 12 and extends into the moving space. When the inner shell 56 moves under the movement of the trigger member 51, there is a gap between the inner shell 56 and the second outer shell 12. At this time, there is space for the support seat 40 to move, which makes it convenient for the valve ejector pin abutting against the support seat 40 to drive the support seat 40 to move. At this time, the movement of the valve ejector pin controls the valve to be in an open state.

[0076] It is understandable that when the inner shell 56 abuts the second outer shell 12, the support seat 40 has no space to move in the moving space. At this time, the valve ejector pin cannot drive the support seat 40 to move, and the valve is in a closed state.

[0077] It should be noted that, in order to prevent the support seat 40 from leaving the moving space, a limiting portion is provided on the end face of the support seat 40 extending into the moving space. When the inner shell 56 abuts against the second outer shell 12, the existence of the limiting portion limits the support seat 40 from completely leaving the moving space, thereby ensuring that when the ejector pin subsequently drives the support seat 40 to move, the gap between the inner shell 56 and the second outer shell 12 can provide travel space for the movement of the support seat 40.

[0078] In one embodiment, a sliding groove 14 with an opening facing away from the first housing 11 is defined in the second housing 12 , and the support seat 40 is slidably disposed in the sliding groove 14 .

[0079] It is understandable that if Figures 2 to 3 As shown, a sliding groove 14 for accommodating the sliding of the support seat 40 is formed on the second housing 12. The sliding groove 14 limits the displacement direction of the support seat 40 to prevent the deviation of the movement of the support seat 40 from affecting the triggering of the valve ejector pin.

[0080] In one embodiment, the second housing 12 partially extends out of the moving space and is connected to a connecting member 13 .

[0081] In order to fix the actuator to the valve, the connecting piece 13 is provided on the second housing 12 , and the valve ejector is passed through the connecting piece 12 . The valve ejector extends into the sliding groove 14 and is connected to the support seat 40 .

[0082] It can be understood that the connecting member 13 is a shell structure, and an internal thread is provided in the connecting member 13. Through the threaded cooperation between the connecting member 13 and the valve, the first shell 10 is fixed to the valve to ensure that the actuator 100 controls the opening and closing of the valve.

[0083] In one embodiment, a plurality of heat dissipation slots 15 are spaced apart on the surface of the first housing 11 .

[0084] In order to improve the heat dissipation efficiency of the copper sleeve 54 and the temperature-variable elastic part 53 in the second shell 12, a plurality of heat dissipation slots 15 are provided on the first shell 11 so that the second shell 12 can directly exchange heat with the external space, thereby improving the heat dissipation efficiency and ensuring the execution efficiency of the control.

[0085] It can be understood that multiple heat dissipation slots 15 are spaced apart on different sides of the first shell 11, so that the multiple heat dissipation slots 15 on the surface of the first shell 11 can be arranged around the second shell 12, so that the second shell 12 can complete heat exchange with the play space in multiple directions, thereby improving the heat exchange efficiency.

[0086] The present invention also provides an electronic device, which includes the actuator 100. The specific structure of the actuator 100 refers to the above embodiment. Since the electronic device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0087] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
