Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0042] Embodiment 1:

[0043] Referring to the attached Figures 1 to 7 , a small-sized detector for a catering kitchen that is waterproof and oil-proof includes a housing 1 and a control main board built inside the housing 1. An opening is formed on the back of the housing 1, and a sealing plate 2 is detachably installed at the opening. On both sides of the top of the housing 1, a speaker 3 and a warning lamp 4 are respectively arranged;

[0044] Both the speaker 3 and the warning lamp 4 are connected to the control main board by the connection methods of the existing technologies, and the control main board controls the speaker 3 and the warning lamp 4. Through the arrangements of the speaker 3 and the warning lamp 4, they are used for performing sound and light alarm work on the detected oil stain or gas situation, thereby improving the comprehensiveness of the alarm;

[0045] The top of the housing 1 is provided with a gourd-shaped suspension opening. By cooperating with screws through the gourd-shaped suspension opening, the suspended installation of the detector can be formed, reducing the contact area between the detector and the wall, decreasing the contact between the wall condensate and the detector, and improving its waterproof effect;

[0046] The bottom of the housing 1 is installed with a detection cylinder 5. Inside the detection cylinder 5, there are a gas sensor 6, a rotatable driving impeller 7, and a torque sensor 8;

[0047] By rotating and driving the impeller 7, not only can the efficiency of the kitchen environmental gas entering the inside of the detection cylinder 5 be accelerated, the detection efficiency of its gas sensor 6 be increased, forming a fast and accurate detection operation, but also it can cooperate with the torque sensor 8 to detect the torque of the impeller 7; when the torque detected by the torque sensor 8 reaches the set value, it is considered that there is oil fume caking, and a reminder for cleaning is given;

[0048] By detecting the gas concentration in the environment, when the gas concentration in the environment reaches the set value, an alarm prompt is given, and actuators such as valves are controlled. The product of this patent is specially designed for this catering kitchen scenario to solve the problems of water vapor and oil fume;

[0049] On both sides of the bottom of the housing 1, there are wire threading assemblies 9 that are inclined downward;

[0050] By setting the wire threading assemblies 9 in a downward-inclined manner, the inclination angle can be set to 45 degrees, so that when water vapor or oil fume condenses on the power cord, it will not seep into the housing 1 along the power cord and damage the electrical components.

[0051] Refer to the appendix Figure 3 and Figure 4 The detection cylinder 5 includes a connecting cylinder 51 fixed to the bottom of the housing 1 and an assembly cylinder 52 threadedly installed at the bottom of the connecting cylinder 51;

[0052] Since the detection cylinder 5 includes the connecting cylinder 51 and the assembly cylinder 52 threadedly installed at the bottom of the connecting cylinder 51, it is not only convenient to carry out protective treatment on some detection components, but also has good disassembly and assembly functions, and further facilitates subsequent cleaning work, improving the accuracy of its gas detection;

[0053] The gas sensor 6 is installed at the inner top of the connecting cylinder 51, and a gas release port is opened at the inner top of the connecting cylinder 51;

By pulling the cover plate 54 downward, the cover plate 54 can be opened to form the gas detection work of gas flow. By moving the cover plate 54 upward, the open end at the bottom of the assembly cylinder 52 can be blocked to form the self-protection work of the detection cylinder 5. By adsorbing the cover plate 54 on the bottom of the assembly cylinder 52, the problem of its shielding protection can be ensured.

[0068] When the assembly cylinder 52 is screwed and installed at the bottom of the connecting cylinder 51, the bottom of the connecting cylinder 51 is used to tightly press against the top of the gas collecting hood 55;

[0069] By tightly pressing the top of the gas collecting hood 55 with the bottom of the connecting cylinder 51, it is convenient to automatically form the fastening work of the gas collecting hood 55 after installing the assembly cylinder 52, improving the operation convenience.

[0070] The bottom end of the linkage shaft 11 is fixedly connected with a special-shaped block 12, and the top end of the shaft rod of the impeller 7 is fixedly connected with a special-shaped sleeve 13 for the special-shaped block 12 to insert;

[0079] It should be noted here that both the water stop ring 95 and the elastic ring 97 are made of water-swellable rubber material. When water vapor enters the wire threading assembly 9, the elastic ring 97 and the water stop ring 95 can expand. Through the expansion of the water stop ring 95, its sealing performance and water isolation performance can be further enhanced.
