Description

Technical Field

[0001] This utility model relates to the field of kitchen fire protection products technology, specifically to a kitchen fire alarm. Background Technology

[0002] To prevent damage from fires, fire alarms are typically used in kitchens to detect smoke concentration, giving users time to escape and extinguish the fire, and preventing the accident from escalating. Common smoke alarms usually use photoelectric or ionization sensors. Photoelectric sensors work by detecting the scattering of light by smoke, while ionization sensors detect smoke particles by utilizing the effect of ionization current. However, cooking fumes can easily enter the detection aperture of these sensors, adhering to the optical components inside the sensor or the surface of the ionization chamber, thus affecting the accuracy of smoke detection, leading to false alarms or decreased sensitivity.

[0003] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

Detailed Implementation

[0014] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0015] According to an embodiment of the present invention, a fire alarm for kitchen use is provided.

[0016] Example 1 like Figure 1 As shown in Figure 4, a kitchen fire alarm according to an embodiment of the present invention includes a smoke sensor body 1. The bottom of the smoke sensor body 1 has a mounting groove 11, and the inside of the mounting groove 11 has several detection holes 12. A rotating connecting seat 2 is rotatably connected to the bottom of the mounting groove 11, and the rotating connecting seat 2 is located outside the several detection holes 12. A threaded mounting seat 21 is fixedly connected to the bottom of the rotating connecting seat 2, and an outer protective shell 3 is threadedly connected to the outside of the threaded mounting seat 21. The inside of the outer protective shell 3 has several symmetrically arranged "S"-shaped mounting shells 4, and two symmetrically arranged "S"-shaped mounting shells 4 are interlocked. An exhaust pipe 421 is fixedly connected to the top of two "S"-shaped mounting shells 4, and the top of the exhaust pipe 421 extends into the inside of the detection holes 12. The housing 4 has several road barrier plates 41 fixedly connected inside. The top of the smoke sensor body 1 is fixedly connected to the mounting base 13. The outer protective housing 3 has several sets of symmetrically arranged fastening mounting brackets 31 fastened inside. Several "S"-shaped mounting housings 4 are installed inside the outer protective housing 3 through several sets of fastening mounting brackets 31. In the two symmetrically arranged "S"-shaped mounting housings 4, one side of the "S"-shaped mounting housing 4 is symmetrically fixedly connected to a fastening strip 43, and the other side of the "S"-shaped mounting housing 4 is symmetrically provided with a fastening groove 431. The positions of the fastening strip 43 and the fastening groove 431 are corresponding. The outer side of the road barrier plate 41 is fixedly connected to an adsorption plate 411. The bottom of the "S"-shaped mounting housing 4 is fixedly connected to an air inlet pipe 42, and the bottom of the air inlet pipe 42 extends to the outside of the outer protective housing 3.

[0017] In this technical solution, the smoke sensor body 1 is the main body of the entire fire alarm, used to monitor the smoke and fog inside the kitchen. The mounting groove 11 at the bottom of the smoke sensor body 1 provides space for the opening of the detection hole 12 and the installation of the rotating connecting seat 2. The rotating connecting seat 2 is used to connect with the threaded mounting seat 21 to form a connector for installing the outer protective shell 3. The outer protective shell 3 and the rotating connecting seat 2 are connected by the threaded mounting seat 21, which facilitates the disassembly of the outer protective shell 3. The two symmetrically arranged "S"-shaped mounting shells 4 form a guide component. At this time, the "S"-shaped guide component can prevent smoke from forming a labyrinth structure in the guide component. When smoke and dust enter the interior of the guide component, larger particles such as dust can adhere to the surface of the gap layer, while smoke can enter the detection area through the tortuous channel, which can reduce the amount of smoke entering the detection area. The dust concentration in the area is reduced, which reduces the impact on the internal optical components or ion chamber of the sensor. The outer protective shell 3 is used to provide installation space for the guide assembly. Several road barrier plates 41 located inside the guide assembly are used to further improve the maze path in the entire conveying space. At the same time, they can increase the adhesion area of ​​dust or oil fumes in the smoke, which helps to improve the adsorption of larger particles such as dust in the delay. The adsorption plate 411 located outside the road barrier plate 41 is used to increase the friction between the adsorption plate and larger particles such as dust, which helps to improve the adsorption of larger particles such as dust. The fastening strip 43 and the fastening groove 431 are used to provide fastening connectors for the fastening between the two "S" shaped mounting shells 4. At this time, the two "S" shaped mounting shells 4 are connected by fastening, which can facilitate the disassembly and cleaning of the entire conveying pipeline. The exhaust pipe 421 is used to connect with the detection hole 12. When assembling the entire fire alarm, first align the positions of several air outlet pipes 421 with the positions of several detection holes 12, and then complete the threaded connection between the threaded mounting base 21 and the outer protective shell 3 by rotating the rotating connecting seat 2.

[0018] In summary, with the help of the above-mentioned technical solution of this utility model, when this device is in use, the smoke from the external kitchen enters the interior of the "S"-shaped mounting shell 4 through the air inlet pipe 42. At this time, the smoke flows towards the detection hole 12 in the labyrinth-like guide structure formed by the "S"-shaped mounting shell 4 and the road barrier plate 41. At the same time, when the smoke flows in the guide assembly, larger particles such as dust in the smoke can adhere to the inner wall of the "S"-shaped mounting shell 4 and the adsorption plate 411, reducing the dust content entering the smoke sensor body 1 through the detection hole 12. After a period of use, the threaded mounting seat 21 and the outer protective shell 3 can be disassembled by rotating the rotating connecting seat 2. Then, several sets of snap-fit ​​mounting brackets 31 can be disassembled from the outer protective shell 3. After the snap-fit ​​mounting brackets 31 are disassembled in the outer protective shell 3, the "S"-shaped mounting shell 4 and the snap-fit ​​mounting brackets 31 can be disassembled. Finally, the two snap-fitted "S"-shaped mounting shells 4 can be separated and the interior can be cleaned.

[0019] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
