It should be noted that: the relative arrangement of parts and steps set forth in these embodiments should be construed as exemplary only and not as limiting unless otherwise specifically noted.
As shown in fig. 1-5, in one aspect of the present invention, there is provided a microswitch assembly comprising: the device comprises a first support plate 1, a second support plate 2 which is arranged at an interval with the first support plate 1 and is provided with a rotating shaft structure 21, a microswitch 3 which is fixedly arranged on one side of the second support plate 2 far away from the first support plate 1, and a contact rod 4 which is rotatably arranged on the rotating shaft structure 21.
The microswitch 3 is provided with a switch contact 31, and the switch contact 31 extends outwards from the side part of the microswitch 3. The contact lever 4 is provided with a tilting portion 41 and a pressing portion 42, the tilting portion 41 extends outwards from one side of the first support plate 1 away from the second support plate 2, and the pressing portion 42 can contact with the switch contact 31. When the contact lever 4 is rotated, the direction in which the tilted portion 41 is pressed down toward the first board 1 is the same rotational direction as the direction in which the pressing portion 42 presses the switch contact 31. Thus, when the tilting portion 41 is pressed down toward the first board 1, the contact lever 4 is rotated clockwise as shown in fig. 1 and 2 around the rotating shaft structure 21 as a whole, and the pressing portion 42 is pushed to press the switch contact 31, and finally the micro switch 3 is activated.
Therefore, the microswitch assembly has the advantages that the microswitch 3 can be effectively isolated from a high-temperature cooking cavity through the first support plate 1 and the second support plate 2 which are arranged at intervals, the influence of a high-temperature environment on an elastic element in the microswitch 3 is reduced, the contact rod 4 is added to serve as an intermediate force transmission structure to replace the technical scheme that the switch contact 31 is directly pressed and started by the drawer type frying barrel 6 in the prior art, and the stress size and the movement amplitude of the switch contact 31 are more controllable by controlling the distance relation between the tilting part 41 and the pressing part 42 relative to the rotating shaft structure 21, so that the stability, the reliability and the service life of the microswitch assembly are improved.
In addition, in the utility model, the moving direction of the drawer-type frying barrel 6 relative to the shell 5 is vertical to the pressing direction of the tilting part 41 to the first supporting plate 1, so that the speed and the force when a user pushes the drawer-type frying barrel 6 into the shell 5 are all transmitted by the contact rod 4 to generate certain loss, the pressing speed and the pressing force applied to the switch contact 31 are reduced, and the micro switch 3 is prevented from being broken down due to long-term operation at a higher pressing speed and a higher pressing force.
In a preferred embodiment, the distance between the tilting portion 41 and the rotating shaft structure 21 is greater than the distance between the pressing portion 42 and the rotating shaft structure 21. Therefore, based on the lever principle, the stroke of the pressing part 42 pressing the switch contact 31 will be less than the pressing distance of the tilting part 41 to the first support plate 1, so as to meet the requirement that the pressing stroke of the switch contact 31 needs to be less than the maximum allowable pressing depth. The pressing force of the pressing part 42 pressing the switch contact 31 is greater than the pressing force of the tilting part 41 on the first support plate 1, so that the switch contact 31 is provided with enough pressing force to overcome the elastic force of the elastic element in the switch contact 31, and the micro switch 3 is ensured to be stably started.
In a preferred embodiment, the ratio of the distance between the tilting portion 41 and the hinge structure 21 to the distance between the pressing portion 42 and the hinge structure 21 is 2:1 to 3:1, so that the switch contact 31 has a better pressing depth and pressing force.
In order to make the contact between the switch contact 31 and the pressing portion 42 more accurate and avoid the switch contact 31 being pressed by other parts of the contact rod 4, in a preferred embodiment, the contact rod 4 further includes an inner groove 43 disposed between the rotating shaft structure 21 and the pressing portion 42, and the pressing portion 42 protrudes outward relative to the inner groove 43. Therefore, even if the contact rod 4 has a certain position deviation in long-term use, the pressing part 42 protrudes from other parts of the contact rod 4, so that the contact rod 4 is still in contact with the switch contact 31 through the pressing part 42, and the pressing speed and the pressing force applied to the switch contact 31 are ensured to meet the design requirements.
In a preferred embodiment, when the pressing portion 42 contacts the switch contact 31, the protruding direction of the pressing portion 42 is parallel to the stretching direction of the switch contact 31, so that the stretching direction of the elastic element in the switch contact 31 is consistent with the pressing direction of the switch contact 31, thereby improving the durability of the switch contact 31.
In order to better guide the mutual contact of the raised portion 41 with the corresponding location on the drawer-type fryer vat 6, as shown in fig. 4, in a preferred embodiment the first strip 1 is provided with a contact hole 11, the contact hole 11 being correspondingly located at a position where the raised portion 41 projects outwardly from the first strip 1.

In a preferred embodiment, the side of the contact hole 11 away from the hinge structure 21 is further provided with a guide structure 12, and two side walls of the guide structure 12 extend outward to form flaring structures with gradually increasing intervals. Thus, even if the drawer-type frying barrel 6 is pushed into the housing 5 in a skewed direction, the lift pins 62 will accurately press the tilting portions 41 of the contact rods 4 from the contact holes 11 under the guidance of the two side walls of the guide structure 12, ensuring that the microswitch assembly can be reliably triggered. The two side walls of the guide structure 12 and the two side walls of the contact hole 11 are transited by a smooth curved surface, so that the ejector rod 62 is guided by the guide structure 12 to change the self moving direction more smoothly, and the collision between the drawer type frying barrel 6 and the shell 5 is reduced.
In a preferred embodiment, as shown in fig. 3 and 5, in order to fixedly connect the first support plate 1 and the second support plate 2, the first support plate 1 is provided with a first mounting hole 13, one side of the second support plate 2 close to the first support plate 1 is provided with a first connecting column 22, and the top of the first connecting column 22 is provided with a threaded hole. Thus, the first bracket 1 and the second bracket 2 can be fixedly connected by inserting the screw into the first mounting hole 13 and fastening the screw in the screw hole.
And in order to fixedly connect the micro switch 3 and the second support plate 2, the micro switch 3 is provided with a second mounting hole 32, one side of the second support plate 2 far away from the first support plate 1 is provided with a second connecting column 23 and a buckle 24, the second connecting column 23 can be arranged in the second mounting hole 32 in a penetrating manner, and meanwhile, the buckle 24 can be clamped on one side of the micro switch 3 far away from the second support plate 2, so that the fixed connection between the micro switch 3 and the second support plate 2 is realized.
