Description

Technical Field

[0001] The invention relates to the technical field of temperature sensing devices, and more particularly to a temperature sensing device assembly. Background Art

[0002] In the field of kitchen fire safety, in view of the high-frequency safety hazard of oil pan fires, the prior art often adopts a protection scheme of arranging temperature sensing elements above the stove. The temperature sensing elements are usually connected in联动 with fire extinguishing equipment, and its core working logic is: when a fire accident occurs in the oil pan, the high temperature generated by the flame will be conducted to the temperature sensing element. After the temperature reaches the rated fusing threshold of the temperature sensing element, the temperature sensing element will perform a fusing action, thereby triggering the启动 mechanism of the fire extinguishing equipment, so that the fire extinguishing equipment quickly releases the fire extinguishing agent to achieve rapid disposal of the oil pan fire.

[0003] However, the structures of existing temperature sensing elements are mostly of an exposed design, and usually multiple groups of temperature sensing elements are配合 with steel wires for联动 control; the specific triggering process is that after the temperature sensing piece of any one temperature sensing element fuses, due to the fixed connection relationship between the steel wire and the temperature sensing element, it will牵拉 the other temperature sensing elements to perform a forward sliding action, thereby triggering the启动 switch of the fire extinguishing equipment. This联动 control method has obvious defects: First, the exposed temperature sensing elements and steel wire components are directly exposed to the kitchen fume environment, which is extremely easy to be附着 with oil stains and difficult to clean; Second, the fire triggering requires a multi-step联动 process of temperature sensing piece fusing - steel wire牵拉 - element sliding, there is a significant response delay problem, and it is difficult to meet the timeliness requirement of rapid disposal of oil pan fires; Third, the exposed联动 structure is easy to be误触 during the cleaning operation, which will cause the fire extinguishing equipment to be误启动, resulting in waste of fire extinguishing agent and affecting the normal operation of the kitchen. Summary of the Invention

[0004] In view of the above technical problems, the invention provides a temperature sensing device assembly, in which the steel wire immediately moves after the temperature sensing piece fuses, directly triggering the fire extinguishing device, with sensitive triggering, and can better meet the timeliness requirement of rapid fire disposal; it is provided with a housing to prevent oil stains from entering the gaps between components, prevent误触 during cleaning, and reduce the maintenance and cleaning difficulty.

[0005] The invention adopts the following technical solutions to achieve the technical purpose:

[0006] It should be noted that there are some inaccuracies and unclear expressions in the original text, such as "联动" which may need to be more accurately translated according to the specific context, and "误触" which also lacks a very precise and common English equivalent in this context. The above translation tries to maintain the integrity of the original text as much as possible while making rough translations for these parts.A temperature sensing device assembly includes a housing and a hook, a steel wire, and a temperature sensing plate horizontally installed inside the housing. The hook includes a first swing arm and a second swing arm, the upper ends of which are rotatably connected by a first bearing, and both lower ends are vertically provided with hooks. A second bearing is provided near the hook on the lower end of the front wall of the first swing arm, and a third bearing is provided on the lower end of the rear wall of the second swing arm. The temperature sensing plate includes a base plate and a connecting plate. The bottom surface of the housing is provided with a temperature sensing window adapted to the base plate.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are only used to more clearly correspond to different connection positions in the description, and should not be construed as indicating or implying relative importance.

[0025] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within the components of a compatible model. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Furthermore, unless otherwise specified, all components used in this application are commercially available components, and the connection between different components can be achieved through conventional technical means.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0027] A temperature sensing device assembly, such as Figures 1-5 As shown, it includes a disc-shaped outer shell 1 and a hook 2, a steel wire 3, and a temperature sensing element 4 horizontally installed inside the outer shell 1, wherein, as... Figure 2As shown, the hook component 2 includes a first swing arm 5 and a second swing arm 6. The upper ends of the first swing arm 5 and the second swing arm 6 are rotatably connected by a first bearing 7, and hooks 8 are vertically arranged at their lower ends. A second bearing 9 is arranged near the hook 8 at the lower end of the front wall of the first swing arm 5, and a third bearing 10 is arranged at the lower end of the rear wall of the second swing arm 6. The temperature sensing plate 4 includes a base plate 12 and a connecting plate 11. The bottom surface of the outer shell 1 is provided with a temperature sensing window 16 that matches the base plate 12. The two ends of the connecting plate 11 are detachably connected to the hooks 8. The outer shell 1 has a wire inlet 14 and a wire outlet 15 on both sides for the steel wire 3 to enter and exit, respectively. Figure 5 As shown, the steel wire 3 enters through the inlet 14, passes through the inner side of the third bearing 10, the outer side of the first bearing 7, and the inner side of the second bearing 9, and exits through the outlet 15. Both ends of the steel wire 3 are connected to fire emergency devices through tensioning devices.

[0028] It should be noted that the hook 2 is horizontally set inside the outer casing 1, and the first bearing 7 is fixed inside the outer casing 1. This allows both swing arms to swing around the first bearing 7. The temperature sensing window 16 and the temperature sensing plate 4 are set downwards so that when the oil pan catches fire, the temperature sensing plate 4 will come into contact with the flame immediately and be melted, triggering the fire extinguishing device.

[0029] As a preferred option, such as Figure 2 As shown, the hook 8 is integrally formed with the first swing arm 5 and the second swing arm 6, and the opening of the hook 8 faces outward.

[0030] like Figure 3 As shown, the middle section of the connecting piece 11 is recessed downward and fixedly connected to the upper wall of the bottom piece 12, and the two ends are provided with connecting holes 13 that are adapted to the hook 8; the bottom piece 12 and the edge of the temperature sensing window 16 are fixedly connected to maintain the relative airtightness of the outer shell and facilitate cleaning.

[0031] More preferably, the substrate 12 and the connecting piece 11 are integrally formed, which can be quickly produced by mold.

[0032] It should be noted that the temperature sensing element 4 is made of copper or brass; the outer casing 1 is made of stainless steel.

[0033] The working principle of this invention is as follows:

[0034] Since the steel wire 3 enters through the inlet 14, passes through the inner side of the third bearing 10, the outer side of the first bearing 7, and the inner side of the second bearing 9, and then exits through the outlet 15, and tensioning devices are provided at both ends of the steel wire 3, the steel wire 3 applies an outward force to both the second bearing 9 and the third bearing 10, causing the second swing arm 5 and the third swing arm 6 to have a tendency to rotate outward around the first bearing 7. When the kitchen oil pan catches fire, the temperature sensing plate 4 will be melted by the flame, and the first swing arm 5 and the second swing arm 6 will lose the restriction of the temperature sensing plate 4, and then rotate to both sides under the action of the tensioning device and the steel wire 3. The ends of the steel wire 3 move to both sides to trigger the fire extinguishing device to extinguish the fire.

[0035] The temperature sensing device assembly differs from existing technologies in principle. After the temperature sensing element 4 melts, the steel wire 3 moves immediately, directly triggering the fire extinguishing device. Furthermore, the entire temperature sensing device is equipped with a stainless steel outer shell 1, which can isolate kitchen fumes to the greatest extent, extend the life of internal components, and reduce maintenance difficulty. On the other hand, the outer shell 1 protects the internal structure, facilitates cleaning, avoids accidental activation, and improves practicality.

[0036] Although embodiments of the present invention have been described in the specification, these embodiments are merely illustrative and should not be construed as limiting the scope of protection of the present invention. Various omissions, substitutions, and modifications made without departing from the spirit of the present invention should be included within the scope of protection of the present invention.
