[0039] The following is combined with Figure 1-Figure 5 This application is described in further detail.

[0040] The embodiment of the present application discloses a combined sensor 100 .

[0041] Reference Figure 1-Figure 3 The combined sensor 100 according to the embodiment of the present application comprises: a housing 1, a fixing member 2 and a detection assembly 3. The housing 1 is installed in the cooking device and defines a detection space 11. The detection space 11 forms a communication hole 12 on the outer peripheral wall of the housing 1. In some specific embodiments, along the height direction of the housing 1, the upper end wall of the housing 1 forms a communication hole 12. The detection space 11 is connected to the cooking space in the cooking device through the communication hole 12. The height direction of the housing 1 can refer to Figure 3 The up and down directions in .

[0042] Furthermore, there are multiple communicating holes 12 , and the multiple communicating holes 12 are spaced apart along the radial direction of the housing 1 .

[0043] In some specific embodiments, the cooking device may be an oven, but the present application is not limited thereto. The cooking device may also be an air fryer, etc.

[0044] The fixing part 2 is arranged in the shell 1, and the inner peripheral wall of the shell 1 is provided with a limiting portion 13. Along the height direction of the shell 1, the top wall of the fixing part 2 is limitedly matched with the limiting portion 13, and a first sealing colloid 21 is provided between the bottom wall of the fixing part 2 and the inner peripheral wall of the shell 1. The first sealing colloid 21 is used to seal and fix the fixing part 2 and the shell 1. The detection component 3 is arranged on the fixing part 2, and the detection component 3 includes at least two different types of detection parts 31.

[0045] In some specific embodiments, the detection assembly 3 is disposed at an end of the fixing member 2 near the communicating hole 12, and the detection assembly 3 detects various parameters within the cooking device through the communicating hole 12. In other specific embodiments, the detection assembly 3 is disposed at an end of the fixing member 2 away from the communicating hole 12, the fixing member 2 is provided with a through hole, the detection assembly 3 is opposite to the through hole, and the detection assembly 3 detects various parameters within the cooking device through the through hole provided on the fixing member 2 and the communicating hole 12, and the detection assembly 3 and the fixing member 2 are sealed.

[0046] In some specific embodiments, the detection component 3 may be adhered to the fixing member 2 , and in other specific embodiments, the detection component 3 may be snap-connected to the fixing member 2 .

[0047] In some specific embodiments, the two different types of detection elements 31 may be a temperature detection element 32 and a humidity detection element 33, etc. In other specific embodiments, the two different types of detection elements 31 may be a pressure detection element 31 and a fan speed detection element 31, etc.

[0048] The first sealing colloid 21 is used to seal the gap between the fixing member 2 and the inner peripheral wall of the shell 1, which can prevent steam and hot air in the cooking device from flowing out to the external environment through the gap between the fixing member 2 and the inner peripheral wall of the shell 1.

[0049] In some specific embodiments, the first sealing colloid 21 may be silica gel, but the present application is not limited thereto. The first sealing colloid 21 may also be epoxy resin or the like.

[0050] Furthermore, there are multiple limiting portions 13 , and the multiple limiting portions 13 are spaced apart along the radial direction of the housing 1 .

[0051] Thus, through the limited engagement of the top wall of the fixing member 2 with the limiting portion 13, and the fixed connection of the bottom wall of the fixing member 2 and the inner peripheral wall of the housing 1 by the first sealing member, the detection assembly 3 is disposed on the fixing member 2, thereby allowing the detection assembly 3 and the housing 1 to be fixedly connected via the fixing member 2. Compared to the prior art, each detection member 31 of the detection assembly 3 does not need to be installed in the housing 1 via threaded fasteners, thereby improving the assembly efficiency of the combined sensor 100.

[0052] Reference Figure 3-Figure 5 In some embodiments of the present application, the fixing member 2 is provided with a plurality of connecting holes 22 , and the plurality of connecting holes 22 are spaced apart along the radial direction of the shell 1 . The detecting member 31 is provided in the connecting hole 22 , and a second sealing colloid 23 is provided between the detecting member 31 and the connecting hole 22 .

[0053] In some specific embodiments, the second sealing colloid 23 may be silica gel, but the present application is not limited thereto. The second sealing colloid 23 may also be epoxy resin or the like.

[0054] In some specific embodiments, the detection component 3 includes two detection parts 31, the two detection parts 31 are respectively a temperature detection part 32 and a humidity detection part 33, there are two connecting holes 22, one of the two connecting holes 22 is provided with a temperature detection part 32, and the other of the two connecting holes 22 is provided with a humidity detection part 33.

[0055] Specifically, the detection member 31 is bonded to the connecting hole 22 through the second sealing colloid 23, thereby achieving the technical effect of fixing the connection between the detection member 31 and the fixing member 2, and the second sealing colloid 23 is used to seal the gap between the detection member 31 and the connecting hole 22, which can prevent the steam and hot air in the cooking equipment from flowing out to the external environment through the gap between the connecting hole 22 and the detection member 31.

[0056] Furthermore, the detection member 31 can be interference fit with the connecting hole 22. In this way, the detection member 31 can be fixed to the connecting hole 22 by interference fit, and the operator does not need to hold the detection member 31 with his hands to maintain the detection member 31 and the connecting hole 22 in a fixed relative position, thereby minimizing the difficulty of applying the second sealing colloid 23 between the connecting hole 22 and the detection member 31, thereby improving the assembly efficiency of the combined sensor 100.

[0057] Reference Figure 3-Figure 5 In some embodiments of the present application, along the height direction of the shell 1, one end of the detection member 31 passes through the connecting hole 22, and the outer peripheral wall of the other end of the detection member 31 is provided with a stop portion 311. Specifically, the upper end portion of the detection member 31 passes through the connecting hole 22, that is, the upper end portion of the detection member 31 is located above the fixing member 2, and the lower end portion of the detection member 31 is located below the fixing member 2. The upper end portion of the detection member 31 is opposite to the communicating hole 12, and the outer peripheral wall of the lower end portion of the detection member 31 is provided with a stop portion 311.

[0058] The stop portion 311 is opposite to and spaced apart from the lower end wall of the fixing member 2, and the second sealing colloid 23 is arranged between the stop portion 311 and the fixing member 2. Specifically, when the detection member 31 is installed in the connecting hole 22, the upper end portion of the detection member 31 passes through the connecting hole 22, and the stop portion 311 stops at the lower end wall of the fixing member 2, thereby preventing the detection member 31 from directly passing through the connecting hole 22, causing the second sealing colloid 23 to be unable to be applied between the detection member 31 and the fixing member 2. Then the operator applies the liquid second sealing colloid 23 between the stop portion 311 and the lower end wall of the fixing member 2. After the second sealing colloid 23 is cured, the technical effect of using the second sealing colloid 23 to fix the connection between the detection member 31 and the fixing member 2 can be achieved.

[0059] Furthermore, the inner peripheral wall of the connecting hole 22 is provided with a locking portion 221, and the locking portion 221 is suitable for elastic deformation. The locking portion 221 includes a driving portion 222 and a locking protrusion 223. The outer peripheral wall of the detection part 31 is provided with a locking recess 312, and the locking protrusion 223 is suitable for extending into the locking recess 312 to lock the fixing part 2 and the detection part 31. When the driving portion 222 is driven, the driving portion 222 drives the locking protrusion 223 to move away from the locking recess 312 to unlock the fixing part 2 and the detection part 31.

[0060] Specifically, the locking recess 312 is located above the stop portion 311. When the upper end of the detection member 31 passes through the connecting hole 22, the upper end of the detection member 31 stops at the locking protrusion 223. The upper end of the detection member 31 drives the locking portion 221 to bend and deform and move close to the inner wall of the shell 1. When the locking recess 312 is opposite to the locking protrusion 223, the locking portion 221 bends and deforms and moves away from the inner wall of the shell 1. The locking protrusion 223 extends into the locking recess 312 to lock the fixing member 2 and the detection member 31, thereby achieving the technical effect of maintaining the detection member 31 and the fixing member 2 in an unchanged relative position, and reducing the difficulty of applying the second sealing colloid 23 between the stop portion 311 and the bottom wall of the fixing member 2.

[0061] When the operator drives the driving portion 222 to move the locking protrusion 223 toward the inner peripheral wall of the housing 1 , the locking protrusion 223 moves away from the locking recess 312 to unlock the fixing member 2 and the detecting member 31 .
