To make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Referring to fig. 1 to 3, an embodiment of the present invention provides a reset mechanism 100, and the reset mechanism 100 is disposed in a housing 210 of a control box 200. A heater 220 is provided in the case 210 of the control box 200, and the heater 220 is, for example, a PTC (Positive Temperature Coefficient thermal) heater. Illustratively, the heater 220 extends in a first direction (shown as the X-direction in fig. 1-3). A temperature protection switch 230 is installed on one side end surface of the heater 220 in the second direction (as shown in the Y direction in fig. 1 to 3), and the temperature protection switch 230 is connected in series to the heating circuit of the heater 220. Illustratively, the second direction is perpendicular to the first direction.

The temperature protection switch 230 includes a reset rod 231, and when the temperature of the heater 220 exceeds the set temperature, the reset rod 231 is deformed by heat and pops up, so that the heating circuit of the heater 220 is disconnected, the heater 220 is prevented from being overheated, and a safety protection effect is achieved. When the heater 220 needs to be heated continuously, the reset mechanism 100 of the present embodiment manually resets the reset rod 231 of the temperature protection switch 230 to close the heating circuit of the heater 220, so that the heater 220 can be heated.

Referring to fig. 3, the reset mechanism 100 of the embodiment of the present application includes a pressing part 120, a transmission part 130 is connected to the pressing part 120, and the transmission part 130 includes a link 131 extending along the second direction and a reset plate 132 connected to the link 131. Illustratively, along the second direction (shown in the Y direction in fig. 3), one end of the link 131 is provided with a pressing part 120, and the pressing part 120 is used for being operated by a user to move the link 131 along the second direction. The other end of the link 131 is provided with a first connection portion 1312. Specifically, the connecting rod 131 is a plate-shaped structure having a certain width, and a reinforcing rib is disposed on the plate-shaped structure to ensure the strength of the connecting rod 131.

Referring to fig. 4, the reset plate 132 extends in a third direction (as shown in a Z direction in fig. 4), a first rotating shaft 1321 and a second rotating shaft 1322 are sequentially disposed along an extending direction of the reset plate 132, the first rotating shaft 1321 and the second rotating shaft 1322 extend in the first direction (shown in an X direction in fig. 4), respectively, and the second rotating shaft 1322 is disposed below the first rotating shaft 1321 in the extending direction of the reset plate. The reset plate 132 can rotate around the second rotation shaft 1322. The first rotating shaft 1321 is disposed at one end of the extending direction of the reset plate 132 and is rotatably connected to the first connecting portion 1312, that is, the first rotating shaft 1321 can rotate in the first connecting portion 1312, so that an included angle between the reset plate 132 and the connecting rod 131 is changed. For example, when the reset plate 132 and the connecting rod 131 are in the initial position, the included angle therebetween is an obtuse angle. When the link 131 drives the reset plate 132 to rotate to reset the reset lever 231 of the temperature protection switch 230, an included angle therebetween is an acute angle. The first connecting portion 1312 may be an annular mounting groove to facilitate the snap-fit mounting with the first rotating shaft 1321.

Illustratively, the first rotating shaft 1321 and the second rotating shaft 1322 of the reset plate 132 both extend outward symmetrically from both side end surfaces of the reset plate 132. In one embodiment, two first rotating shafts 1321 and two second rotating shafts 1322 are symmetrically installed on both side end surfaces of the reset plate 132. As another embodiment, the first rotating shaft 1321 and the second rotating shaft 1322 are both shafts, and each shaft penetrates through the restoring plate 132 along a first direction (as shown in the X direction in fig. 1 to 3), and both end portions of each shaft are exposed to both end surfaces for a certain distance. In this embodiment, the first rotating shaft 1321 may directly penetrate the upper end portion of the reset plate 132 and the first coupling portion 1312 in the first direction during installation, so that the reset plate 132 and the first coupling portion 1312 may be rotatably coupled to each other, and the assembling operation may be simple.

Referring to fig. 5, and also to fig. 2 to 4, the other end of the reset plate 132 in the extending direction is for being disposed opposite to the reset lever 231 in the second direction. Illustratively, the other end of the extending direction of reset plate 132 (i.e., the free end of reset plate 132) is provided with a protrusion forming abutment 1323, and the abutment 1323 is disposed opposite to the reset rod 231 of the temperature protection switch 230 in the second direction.

In the embodiment of the present application, the link 131 can move forward in the second direction to drive the reset plate 132 to rotate around the axis extending in the first direction, so that the other end of the reset plate 132 moves toward the reset lever 231 in the second direction to press the reset lever 231, so that the reset lever 231 is reset. And, the link 131 is capable of moving in the second direction in the opposite direction, so that the other end of the reset plate 132 moves away from the reset lever 231 in the second direction, preventing the reset plate 132 from obstructing the reset lever 231 from popping out.

That is, the link 131 can move in the forward direction (as shown in the direction D in fig. 2 to 4) in the second direction to drive the reset plate 132 to rotate along the second rotating shaft 1322, so that the abutting portion 1323 of the reset plate 132 moves toward and contacts the reset lever 231 in the second direction, and as the link 131 continues to move in the second direction, the reset plate 132 continues to rotate, so that the abutting portion 1323 presses the reset lever 231, the reset lever 231 is reset, the heating circuit of the heater 220 is closed, and the heater 220 can heat.

After the reset rod 231 is reset, the link rod 131 can move reversely in the second direction (as shown in direction E in fig. 2 to 4) to drive the reset plate 132 to rotate along the second rotation shaft 1322, so that the abutting portion 1323 of the reset plate 132 moves away from the reset rod 231 in the second direction, and the abutting portion 1323 is prevented from obstructing the ejection of the reset rod 231.

Referring to fig. 6, referring to fig. 2 and 3, the reset plate 132 is mounted on the fixing base 140 through a second rotating shaft 1322, and the fixing base 140 is used for limiting the second rotating shaft 1322 to move along the second direction. Illustratively, the fixing base 140 is installed at a side of the heater 220 where the temperature protection switch 230 is installed, and the fixing base 140 may be connected with the heater 220 by a bolt. The fixing base 140 includes a second connecting portion 142, and the second rotating shaft 1322 is rotatably connected to the second connecting portion 142. That is, the reset plate 132 is rotatably connected to the second connecting portion 142 of the fixing base 140 through the second rotating shaft 1322, and the fixing base 140 corresponds to a pivot point of the reset plate 132.

Illustratively, the second connecting portion 142 is a U-shaped groove with an opening as shown in the direction C in fig. 6, and the second rotating shaft 1322 is accommodated in the U-shaped groove and is rotatably connected with the U-shaped groove. The U-shaped groove is configured to facilitate the installation of the second rotating shaft 1322 into the second connecting portion 142 during assembly. Further, a fixing portion 141 for fixing the temperature protection switch 230 is further provided on an end surface of the fixing base 140 close to the heater 220. The fixing portion 141 is exemplarily a stepped clamping groove, and referring to fig. 7, the edge position of the temperature protection switch 230 is clamped by a stepped structure, and the temperature protection switch 230 is press-fitted between the fixing portion 141 and the heater 220, so as to implement the installation of the temperature protection switch 230 on the heater 220. Meanwhile, the reset lever 231 can be ejected in the second direction and is opposite to the abutting portion 1323 in the second direction.

Hereinafter, a process of manually resetting the reset lever 231 of the temperature protection switch 230 by the reset structure 100 according to the embodiment of the present application will be described in detail with reference to the accompanying drawings.

In this embodiment, when the temperature protection switch 230 needs to be reset, the pressing portion 120 at one end of the connecting rod 131 can be pressed along the second direction (as shown in the direction D in fig. 2 to 4) to move the pressing portion 120 inward for a certain distance along the second direction, and the connecting rod 131 is pushed by the pressing portion 120 to move along the second direction (as shown in the direction D in fig. 2 to 4) for a corresponding distance. Since the second connecting portion 142 limits the movement of the second rotating shaft 1322 in the second direction, during the forward movement of the connecting rod 131 in the second direction, the second rotating shaft 1322 only rotates in the second connecting portion 142 but does not move in the second direction, and the first rotating shaft 1321 rotates in the first connecting portion 1312 while moving along with the connecting rod 131 in the second direction, so that the reset plate 132 can swing with the second connecting portion 142 as a supporting point and the second rotating shaft 1322 as an axis.

In this process, the abutting portion 1323 of the reset plate 132 approaches the reset rod 231 in the second direction until contacting the reset rod 231 and pushing it back to the initial position, so that the temperature protection switch 230 is restored to the initial state, the heating circuit is turned on, the heater 220 can heat, and the operation is simple and convenient. That is, the link 131 moves inward in the second direction to drive the reset plate 132 to rotate around the second rotating shaft 1322, so that the abutting portion 1323 moves toward and contacts the reset lever 231 in the second direction, and as the link 131 continues to move in the second direction, the reset plate 132 continues to rotate, so that the abutting portion 1323 presses the reset lever 231, the reset lever 231 is reset, the heating circuit of the heater 220 is closed, and the heater 220 can heat.

After the reset rod 231 is reset, the connecting rod 131 can be moved reversely in the second direction (as shown in E direction in fig. 2 to 4) by the pressing portion 120, and further the reset plate 132 is driven to swing in the direction opposite to the resetting process, so that the abutting portion 1323 is far away from the reset rod 231 in the second direction, and the abutting portion 1323 is prevented from hindering the next ejection of the reset rod 231.

Referring to fig. 8 and 9, the reset mechanism 100 further includes a limiting member 150 installed above the fixing base 140 along a third direction (shown as a Z direction in fig. 9). The position-limiting member 150 includes a slot 151, and the slot 151 is opened in a direction opposite to the direction B shown in fig. 9, and is opposite to the notch of the second connecting portion 142. The locking groove 151 is fastened to the second rotating shaft 1322 along the third direction, so as to prevent the second rotating shaft 1322 from moving along the third direction. As a specific embodiment, the second connecting portions 142 are staggered with the slots 151, that is, the slots 151 are located outside the second connecting portions 142 (not shown in fig. 8) along the first direction, and the slots 151 press down on the end of the second rotating shaft 1322 along the third direction. The position of the second rotating shaft 1322 is restricted by the support of the second connecting portion 142 and the engagement of the locking groove 151, and is prevented from being displaced in the second direction and the third direction when moving. As another embodiment, the second connecting portion 142 may also be disposed opposite to the slot 151 in a third direction (not shown in the figure), so that the second rotating shaft 1322 is limited in an annular space formed by the second connecting portion 142 and the slot 151, and the second rotating shaft 1322 is prevented from moving in the second direction and the third direction.

Specifically, referring to fig. 6 and 9, the fixing base 140 is provided with a first connecting column 143 and a second connecting column 144. The limiting member 150 is correspondingly provided with a first connection hole 153 and a second connection hole 154. In the third direction, the first coupling holes 153 correspond to the first coupling posts 143, and the second coupling holes 154 correspond to the second coupling posts 144. The limiting member 150 and the second connecting portion 142 can be fixed together by connecting the first connecting hole 153 with the first connecting post 143 and connecting the second connecting hole 154 with the second connecting post 144. Illustratively, the fixing means may be bolt fixing.

Referring to fig. 8 and 9, the limiting member 150 further includes an extension plate 155 extending in the second direction, the extension plate being located above the connection rod 131 in the third direction, the extension plate 155 being close to the upper end surface of the connection rod 131 for providing a guide for the connection rod 131 to move in the second direction and limiting the connection rod 131 from moving in the third direction. That is, the extension plate 155 serves as a limit guide. Further, referring to fig. 4, the line of the temperature protection switch 230 needs to pass through the connecting rod 131 and the extending plate 155, so that a first yielding groove 1313 is formed at an end of the connecting rod 131, and a second yielding groove 152 is formed at an end of the extending plate of the limiting member 150, so as to facilitate connection of the line.

In a specific implementation manner of this embodiment, an end of the connecting rod 131 may serve as the pressing portion 120, and in this case, the end of the connecting rod 131 extends out of the control box 200, so as to be pressed by a user.

Referring to fig. 4, in another embodiment of the present embodiment, the pressing part 120 includes a first link 123 connected to one end of the link 131, and a button cap 121 connected to the other end of the first link 123. Illustratively, the first connection member 123 extends in the second direction. Further, the first connecting member 123 is provided with an empty slot 1232 penetrating along the first direction or the second direction, and the empty slot 1232 extends from the connection position of the first connecting member 123 and the button cap 121 to the other end along the second direction for a certain distance. That is, the joint of the first connecting member 123 and the button cap 121 is a non-solid joint, so that the button cap 121 is prevented from deforming at the joint with the first connecting member 123, and the appearance is prevented from being affected.

Referring to fig. 4 and also to fig. 2, the present embodiment further includes a button seat 110, and the button seat 110 is fixedly mounted on the housing 210 of the control box 200.
