Description

Technical Field

[0001] The utility model belongs to the technical field of oil filter systems, and in particular relates to a micro switch control component of an oil filter system. Background Art

[0002] Western-style electric deep fryers used in restaurants typically have a built-in oil filtration system. This process typically involves two steps: the first mechanically opening the oil return valve in the pipeline, such as a valve handle. The second step involves circuitry controlling the oil pump, such as a pushbutton switch. This design makes the oil filtration process cumbersome and can result in oil residue in the pipeline. Incorrect operation sequences can even lead to pump or pipeline failures. These issues can lead to unsatisfactory performance, necessitating the use of a microswitch control component within the oil filtration system.

[0003] Most existing micro-switch control components for oil filtration systems utilize separate control structures, meaning the oil valve and oil pump are controlled separately. If the oil pump is activated before the oil valve when activating the oil filtration function, oil can be trapped in the pipeline, and the resulting instantaneous oil pressure can damage the pump and pipeline. Furthermore, if the oil pump is shut off before the oil valve when deactivating the oil filtration function, oil can remain in the pipeline. These potential problems can lead to equipment failure, waste of cooking oil, and are cumbersome to operate, requiring significant labor and resources. Furthermore, existing micro-switch control components for oil filtration systems require a dedicated bracket to secure them to the equipment, making installation and removal difficult and inconvenient for long-term use and maintenance. Utility Model Content

[0004] The technical problem to be solved by the present invention is that most of the existing micro switch control components of the oil filter system are separately controlled structures and cannot be controlled in an integrated manner, which makes the equipment prone to failure. In addition, a special bracket is required to fix the component on the equipment, which is difficult to install and disassemble, and is inconvenient for long-term use and maintenance.

[0005] In order to solve the above technical problems, the technical solution provided by the utility model is a micro switch control assembly of an oil filter system, comprising a plurality of micro switches and a connecting rod, wherein the connecting rod is an L-shaped structure with one end bent, and a first fixing plate and a second fixing plate are inserted into the connecting rod, the plurality of micro switches are fixed between the first fixing plate and the second fixing plate by a plurality of fixing bolts, and an insulating gasket is arranged between the plurality of micro switches, a cam is arranged at the connecting rod between the first fixing plate and the second fixing plate, and a connecting bracket is inserted into the end of the connecting rod away from the bend.

[0006] Preferably, the first fixing plate and the second fixing plate are both L-shaped bent sheet metal structures.

[0007] Preferably, a plurality of fixing strip holes are provided on the bent surface of the top of the first fixing plate.

[0008] Preferably, the length of the bent surface of the top of the second fixing plate matches the width of a plurality of micro switches in the middle, and one side of the second fixing plate is fixedly connected to the first fixing plate through a plurality of mounting bolts.

[0009] Preferably, the plurality of fixing bolts pass through the second fixing plate from one side of the first fixing plate and are fixedly connected through corresponding nuts.

[0010] Preferably, the inner diameter of the cam matches the diameter of the connecting rod, and the bottom of the cam is fixedly connected to the connecting rod through a positioning bolt. The convex surface of the cam abuts against the bottoms of a plurality of micro switches.

[0011] Preferably, the end of the connecting rod inserted into the connecting bracket is a square boss, and the side length of the square boss is smaller than the diameter of the connecting rod. The connecting bracket is integrally of a U-shaped structure, and a limiting block is provided at one end of the U-shaped structure of the connecting bracket away from the connecting rod.

[0012] The advantages of the present utility model compared with the prior art are as follows:

[0013] The micro switch control component of the present oil filtering system can synchronously control a plurality of micro switches through a cam after fixing them, so that a plurality of oil pumps and oil valves can be simultaneously controlled by rotating the connecting rod. It not only has a simple structure, but also can prevent problems caused by equipment control. At the same time, the switch control component is fixed by the first fixing plate, which is convenient for disassembly and maintenance. Description of the Drawings

[0022] Example 1:

[0023] As the instruction manual Figures 1-4 As shown, a micro switch control assembly of an oil filter system includes multiple micro switches 1 and a connecting rod 2. The connecting rod 2 is an L-shaped structure with one end bent. A first fixing plate 3 and a second fixing plate 4 are inserted into the connecting rod 2. The first fixing plate 3 and the second fixing plate 4 are both L-shaped bent sheet metal structures. A plurality of fixing bar holes 9 are provided on a bent top surface of the first fixing plate 3. Multiple micro switches 1 are fixed between the first fixing plate 3 and the second fixing plate 4 by multiple fixing bolts 5, and insulating gaskets 6 are provided between the multiple micro switches 1. The length of a bent top surface of the second fixing plate 4 matches the width of the multiple micro switches 1 in the middle, and one side of the second fixing plate 4 is fixedly connected to the first fixing plate 3 by a plurality of mounting bolts 10. Multiple fixing bolts 5 pass through the second fixing plate 4 from one side of the first fixing plate 3 and are fixedly connected by corresponding nuts 11.

[0024] In the present utility model, a cam 7 is disposed between the first fixing plate 3 and the second fixing plate 4 at the position of the connecting rod 2. The inner diameter of the cam 7 matches the diameter of the connecting rod 2, and the bottom of the cam 7 is fixedly connected to the connecting rod 2 through a positioning bolt 12. The convex surface of the cam 7 abuts against the bottoms of a plurality of microswitches 1. One end of the connecting rod 2 away from the bend is inserted with a connecting bracket 8. The end of the connecting rod 2 inserted into the connecting bracket 8 is a square boss, and the side length of the square boss is smaller than the diameter of the connecting rod 2. The connecting bracket 8 is integrally of a U-shaped structure, and a limiting block 13 is provided at the end of the U-shaped structure of the connecting bracket 8 away from the connecting rod 2, and is connected to the switch of an external oil valve 14 through the limiting block 13.

[0026] When the present utility model is specifically implemented, the microswitch control assembly of the oil filtering system is fixed through a plurality of fixing strip holes 9 at the bent portion above the first fixing plate, and the rotation of the cam 7 on the control connecting rod 2 is used to control the on-off of the plurality of microswitches 1. Moreover, the connection between the connecting rod 2 and the connecting bracket 8 can also control the on-off of the oil valve 14 connected to the limiting block 13 at the other end of the connecting bracket 8. Combining them can control the circuit and the oil valve 14 simultaneously.

[0027] The structure of the cam 7 is stable. It is fixed between the first fixing plate 3 and the second fixing plate 4 through the positioning bolt 12, and the microswitch control assembly of the oil filtering system itself will not be deformed during long-term movement.
