Description

Technical Field

[0001] This utility model relates to the field of cooking machine technology, and in particular to a detachable knife detection device for a stir-fry machine. Background Technology

[0002] In modern smart kitchen equipment, the automation level of automatic cooking machines is constantly improving, with the detachable blade design greatly facilitating cleaning and maintenance for users. However, users of existing automatic cooking machines still need to manually check whether the blades are properly installed, a cumbersome and easily overlooked process.

[0003] Existing detection technologies have limitations: some solutions use mechanical microswitches or pressure sensors, but these suffer from problems such as easy wear, low accuracy, and susceptibility to oil contamination, resulting in insufficient reliability. Summary of the Invention

[0004] To address the aforementioned pain points, this utility model proposes a simple and reasonable tool detection device based on an infrared sensor.

[0005] This utility model provides a detachable knife detection device for a cooking machine, including a base and a knife shaft rotatably connected to the base, and a knife detachably connected to the knife shaft; the knife includes a connecting part and a stirring part, and a reflective surface is provided on the end face of the connecting part facing one end of the base; the base is also provided with an infrared sensor that can emit and receive infrared rays toward the reflective surface.

[0006] The beneficial effects of this invention are: by setting the reflective surface on the end face of the connector, an infrared sensor emits infrared rays towards the reflective surface, and the installation of the cutting tool is detected by whether infrared rays are received. The overall structure is simple and reasonable, not easily worn, and has high reliability.

[0007] Furthermore, the base is provided with a receiving hole adapted to the insertion of the connecting part.

[0008] The beneficial effect of adopting the above-mentioned further solutions is to prevent oil contamination.

[0009] Furthermore, the base includes a housing and a power assembly fixed on the housing. The power assembly includes a stator and a cutter shaft that rotates relative to the stator. The receiving hole is provided on the housing. The stator of the power assembly is fixed on the housing. The cutter shaft extends into the receiving hole. The infrared sensor is fixed at the bottom of the stator of the power assembly at a position corresponding to the receiving hole.

[0010] The advantages of adopting the above-mentioned further solutions are: the overall structure is simple and reasonable, and it is easy to manufacture.

[0011] Furthermore, the bottom of the receiving hole is isolated from the infrared sensor by a transparent material.

[0012] The advantage of adopting the above-mentioned further solution is that if oil gets into the receiving hole, it can be cleaned, thus avoiding direct contamination of the infrared sensor by the oil.

[0013] Furthermore, a crown-shaped reflector is provided at the end of the connecting part near the base, and the reflective surface is located on the reflector.

[0014] The advantages of adopting the above-mentioned further solution are: the crown-shaped reflector not only increases the area of ​​the reflective surface and improves the detection accuracy, but also prevents oil stains from entering.

[0015] Furthermore, a sealing ring is provided on the connecting part, the sealing ring is used to abut against the inner wall of the receiving hole to form a sealing area, and the reflective surface is located within the sealing area.

[0016] The advantage of adopting the above-mentioned further solution is that it avoids oil or steam entering the receiving hole during the cooking process, thus preventing it from affecting the accuracy of the detection. Attached Figure Description

[0021] The present invention will be further described below with reference to the embodiments.

[0022] like Figures 1 to 4 As shown, this embodiment discloses a detachable knife detection device for a cooking machine, including a base 1, a knife shaft 2 rotatably connected to the base 1, and a knife 3 detachably connected to the knife shaft 2. The knife 3 includes a connecting part 31 and a stirring part 32. A reflective surface is provided on the end face of the connecting part 31 facing the base 1. An infrared sensor 11 that can emit and receive infrared rays towards the reflective surface is also provided on the base 1. By setting the reflective surface on the end face of the connecting part 31, the infrared sensor 11 emits infrared rays towards the reflective surface, and the installation of the knife is detected by whether infrared rays are received. The overall structure is simple and reasonable, not easy to wear, and has high reliability.

[0023] The base 1 is provided with a receiving hole 121 for insertion of the connecting part 31 to prevent oil from entering.

[0024] The base 1 includes a housing 12 and a power assembly 13 fixed on the housing 12. The power assembly 13 includes a stator 131 and a cutter shaft 2 that rotates relative to the stator 131. A receiving hole 121 is provided on the housing 12. The stator 131 of the power assembly 13 is fixed on the housing 12, and the cutter shaft 2 extends into the receiving hole 121. The infrared sensor 11 is fixed at the bottom of the stator 131 of the power assembly 13 at a position corresponding to the receiving hole 121. The overall structure is simple and reasonable, and easy to manufacture.

[0025] The bottom of the receiving hole 121 is isolated from the infrared sensor 11 by a transparent material 1311. If oil gets into the receiving hole 121, it can be cleaned to prevent the oil from directly contaminating the infrared sensor 11.

[0026] A crown-shaped reflector plate 311 is provided at the end of the connecting part 31 near the base 1, and the reflective surface is located on the reflector plate 311. The crown shape of the reflector plate 311 not only increases the area of ​​the reflective surface and improves the detection accuracy, but also prevents oil stains from entering.

[0027] A sealing ring 312 is provided on the connecting part 31. The sealing ring 312 is used to form a sealing area against the inner wall of the receiving hole 121, and the reflective surface is located within the sealing area. This prevents oil or steam from entering the receiving hole 121 during cooking and affecting the detection accuracy.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
