[0030] The following is combined with Figure 1-8 The contents of the specific implementation modes of the present invention are described in detail:

[0031] The embodiment of the present invention provides a protector, which has a multifunctional safety protector with dual functions of adjusting temperature and power-off when falling. One part of the present invention realizes the function of adjustable thermostat, and the other part realizes the function of fall switch. In the production and assembly of products, it is not necessary to assemble two electrical components, the adjustable thermostat and the fall switch, at the same time, and only one electrical component of the present solution needs to be assembled. In this way, the process can be reduced and the production efficiency can be improved. The cost is reduced and the market competitiveness of the product is improved.

[0032] The protector of the embodiment of the present invention, the multifunctional protector of the present invention includes a temperature control adjustment system and a tipping protection system. It includes: a fixed structure, a first reed 51, a second reed 52, a third reed 53, a first terminal 31, a second terminal 32, an adjustment device 2 and a swinging member; the first reed 51 has a first end and a second end; the second reed 52 has a third end and a fourth end; the third reed 53 has a fifth end and a sixth end; the first reed 51 is electrically connected to the first terminal 31, and the first end of the first reed 51 is fixedly connected to the fixed structure; the second end of the first reed 51 is fixed to the fourth end of the second reed 52, and the third end of the second reed 52 is a free end: a first contact 91 is formed on the fifth end of the third reed 53, the fifth end is a free end, and the sixth end is fixed to the third end of the second reed 52; the swinging member The invention comprises a swing arm 62 and a weight 61, which can swing relative to the fixed structure; a second contact 92 is formed on the second terminal 32; the adjusting device 2 can move relative to the fixed structure, so as to apply pressure to the first spring 51. After the first spring 51 is subjected to force, the first spring 51 applies pressure to the second spring 52, so that the free end of the second spring 52 moves, and the free end of the second spring 52 drives the free end of the third spring 53 to move, so that the first contact 91 and the second contact 92 are in contact; when the fixed structure is tilted to a preset degree, the swing arm 62 can swing relative to the fixed structure to a preset position and apply pressure to the third spring 53, so that the first contact 91 on the third spring 53 is disconnected from the second contact 92. That is, the preset degree can be specifically set according to actual needs, such as being determined according to the tilt degree of the heater. When the tilt angle is small, such as when its position is moved, the tilt protection will not be caused. Only when it reaches a certain degree, the tipping protection will be triggered.

[0033] The fixing structure includes a first fixing plate 11 and a second fixing plate 12, and the first fixing plate 11 and the second fixing plate 12 are fixed together by a first connecting member 8. The first connecting member 8 can be a hollow rivet.

[0034] The first connector 8 passes through the first fixing sheet 11, the first terminal 31, the first spring sheet, the second terminal 32, and the second fixing sheet 12 to fix them together. A first insulating ring 41 is further provided between the first fixing sheet 11 and the first terminal 31, a second insulating ring 42 is provided between the first spring sheet and the second terminal 32, and a third insulating ring 43 is provided between the second terminal 32 and the second fixing sheet 12; the first connector 8 passes through the first, second, and third insulating rings 43.

[0035] The adjusting device 2 can rotate relative to the fixed structure, so that the adjusting device 2 can move forward and backward relative to the fixed structure. The adjusting device 2 is also fixed with a first ceramic column 71, and pressure is applied to the first reed 51 through the first ceramic column 71.

[0036] The second fixing plate 12 is also fixed to one end of the second ceramic column 72 . The other end of the second ceramic column 72 forms a conical structure. The second end of the first reed 51 and the fourth end of the second reed 52 are sleeved and fixed to the other end of the second ceramic column 72 .

[0037] A first groove 65 is formed on the swing arm 62, and a first extrusion structure and a second extrusion structure are respectively located on both sides of the first groove 65. When the swing arm 62 swings to the left, the first extrusion structure can apply pressure to the third reed 53, and when the swing arm 62 swings to the right, the second extrusion structure can apply pressure to the third reed 53. Figure 8 As shown, a conical portion 531 is fixed to the third reed 53. When the heater is not tilted, the conical portion 531 is located in the first groove 65. When the swing arm 62 moves left and right, the first extrusion structure and the second extrusion structure squeeze the conical portion 531, thereby applying pressure to the third reed 53, so that the first contact 91 and the second contact 92 on the third reed 53 are separated.

[0038] The adjusting device 2 of the embodiment of the present invention is further provided with a limiting plate, which is used to limit the rotation angle of the adjusting device 2 relative to the first fixing plate 11 . The adjusting device 2 may be an adjusting rod.

[0039] The first insulating ring 41 of the embodiment of the present invention may be a first ceramic ring, the second insulating ring 42 may be a second ceramic ring, and the third insulating ring 43 may be a third ceramic ring.

[0040] The swing arm 62 of the embodiment of the present invention is provided with a swing arm rivet 64, through which the swing arm 62 is rotatably fixed to the second terminal 32, or fixed to the intermediate connecting member, and the intermediate connecting member is fixed to the second terminal 32. The weight 61 is fixed to the swing arm 62 by a pendulum rivet 63.

[0041] The first contact 91 and the second contact 92 of the embodiment of the present invention may be contact rivets.

[0042] When the temperature adjustment function is realized, the adjustment device 2 is rotated clockwise from the disconnected state, and the adjustment device 2 will push the first porcelain column 71 to move to the left, pressing the first spring 51. The elastic structure of the first spring 51 is deformed due to the force, driving the second spring 52, thereby driving the third spring 53 fixed to the second spring 52, and the first contact 91 (rivet) on the third spring 53 contacts the second contact 92 (rivet) on the second terminal 32, thereby generating a passage. The first spring 51 and the second spring 52 can be two parts of a combination within the protection scope of the present invention.

[0043] The adjusting device 2 rotates about 120° from the initial position, and a "beep" sound is heard, indicating that the circuit is connected. Continue to rotate the adjusting device 2 until it is turned to the bottom, which is the effective position of the adjustable temperature controller to control the temperature. From the time the circuit is connected to the position where the adjusting device 2 is turned to the bottom, the pressure on the first reed 51 gradually increases, thereby gradually increasing the pressure on the second reed 52. The second reed 52 is a temperature control spring for detecting temperature. When the second reed 52 is subjected to less force, the temperature sensed by the second reed 52 is smaller, and vice versa. If the pressure is small, a relatively low temperature is required to pop open the second reed 52, thereby separating the first contact 91 and the second contact 92; if the pressure is large, a relatively high temperature is required to pop open the second reed 52 and disconnect the circuit. This principle is used to control the temperature.

[0044] When realizing the function of power-off protection due to falling, when the heater or the fixed structure is severely tilted or falls, the pendulum tilts to the left (the same principle applies to the right) under the action of gravity, thereby driving the swing arm 62 to tilt to the left or right, and the structure on the swing arm 62 props up the third spring leaf 53, and the third spring leaf 53 and the second spring leaf 52 can be connected together by rivets, so that the contact point can be cut, the circuit is disconnected, and the power-off protection is achieved.

[0045] In addition, the present invention provides a heater, including the protector of the present invention. The protector can simultaneously realize the functions of temperature regulation, overheat protection, and tipping protection. The fixing structure of the embodiment of the present invention can be a part of the shell of the heater, or a separate component fixed to the shell of the heater, all of which are within the protection scope of the present invention.

[0046] Beneficial effects:

[0047] The protector and heater of the embodiment of the present invention can adjust the temperature by squeezing the first reed through the adjusting device, so that the second reed drives the first contact on the third reed to combine with the contact of the second terminal; through the cooperation of the swinging member and the third reed, when the heater is tipped over, the first and second contacts can be disconnected to realize the tipping protection function. The present invention realizes that one component replaces the functions of the two components of the adjustable thermostat and the tipping switch. The cost of the heater is reduced, the circuit design is simplified, the wiring structure inside the heater is simpler, and the wiring design is simplified.
