Description

Technical Field

[0001] This utility model relates to heat insulation umbrella technology, specifically to a fire-resistant and heat-insulating umbrella. Background Technology

[0002] In scenarios such as fire escape, high-temperature industrial operations, and fire rescue, fire-resistant and heat-insulating umbrellas, as rapidly deployable temporary protective equipment, must simultaneously meet the core requirements of "blocking open flames" and "isolating high-temperature transmission" to buy users crucial escape or rescue time. However, the existing heat insulation structure design of fire-resistant and heat-insulating umbrellas still has significant technical shortcomings, making it difficult to meet the protection needs in complex high-temperature environments.

[0003] Traditional fireproof and heat-insulating umbrellas often use a single material or a simple layered structure for their insulation components, such as a single layer of high-silica fabric or ordinary fire-resistant cotton. While this type of structure can block open flames through the flame-retardant properties of high-silica fabric, its insulation performance is insufficient. The single-density high-silica fabric is difficult to form an effective thermal buffer gradient. When the external ambient temperature reaches 500°C or higher, heat can easily be conducted rapidly through the fabric fibers to the protected side, causing the temperature inside the umbrella to rise to the human body's tolerance limit (usually exceeding 60°C) in a short period of time, leading to the risk of skin burns or heatstroke. Utility Model Content

[0004] The purpose of this invention is to provide a fireproof and heat-insulating umbrella to solve the problem that the heat insulation part of traditional fireproof and heat-insulating umbrellas in the prior art uses a single material or a simple layered structure, resulting in limited heat insulation effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fireproof and heat-insulating umbrella, including an umbrella canopy, a handle at the bottom of the umbrella canopy, and a drawstring fixedly installed at the top of the umbrella canopy;

[0006] A heat insulation component, wherein the heat insulation component is disposed at the bottom of the umbrella canopy;

[0007] The heat insulation component includes an umbrella rib section and a heat insulation section, both of which are located at the bottom of the umbrella surface.

[0008] Warning component, wherein the warning component is disposed inside the umbrella handle;

[0009] The warning component includes a warning part and a switch part, both of which are located inside the umbrella handle.

[0010] The heat insulation component includes an outer layer, an aluminum foil film fixedly connected to the inner side of the outer layer, an inner layer fixedly connected to the inner side of the aluminum foil film, and the surface of the outer layer fixedly connected to the umbrella surface.

[0011] Furthermore, the umbrella rib portion includes a top seat, on the side of the top seat is a first umbrella rib rotatably mounted, on the middle of the first umbrella rib is a second umbrella rib rotatably mounted, on one end of the second umbrella rib is a sleeve rotatably mounted, inside the sleeve is a locking block movably mounted, and on one side of the locking block is a spring fixedly connected.

[0012] Furthermore, the top seat is fixedly installed at the top of the umbrella handle, the sleeve is sleeved between the umbrella handle, the locking block is movably installed inside the umbrella handle, one end of the locking block passes through the umbrella handle and the sleeve in sequence, and one end of the locking block extends to the outside of the sleeve, one end of the spring is fixedly connected to the inner wall of the umbrella handle, one end of the umbrella rib is fixedly installed to the inner layer, and the top seat is fixedly installed to the outer layer and the inner layer respectively.

[0013] Furthermore, the warning area includes a protective cover, a miniature temperature sensor is provided at the bottom of the protective cover, and a flashing ring light is fixedly installed at one end of the umbrella handle near the top.

In addition, an aluminum foil film is laminated in the inner layer with a high temperature resistant adhesive. The high reflectivity of aluminum foil to infrared heat radiation is used to reflect the heat radiation in the high temperature environment back, reducing the heat transfer to the protected side, thus achieving the effect of further heat insulation and high temperature resistance of the heat insulation umbrella.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] As attached Figure 1 To be continued Figure 5 As shown:

[0029] Example 1:

[0030] This utility model provides a fireproof and heat-insulating umbrella, including an umbrella surface 1, an umbrella handle 2 at the bottom of the umbrella surface 1, and a drawstring 5 fixedly installed at the top of the umbrella surface 1.

[0031] Heat insulation component 3 is disposed at the bottom of umbrella surface 1;

[0032] The heat insulation component 3 includes an umbrella rib part 31 and a heat insulation part 32, both of which are located at the bottom of the umbrella surface 1.

[0033] The heat insulation part 32 includes an outer layer 321, an aluminum foil film 322 is fixedly connected to the inner side of the outer layer 321, an inner layer 323 is fixedly connected to the inner side of the aluminum foil film 322, and the surface of the outer layer 321 is fixedly connected to the umbrella surface 1.

[0034] The umbrella rib section 31 includes a top seat 311, a first umbrella rib 312 rotatably mounted on the side of the top seat 311, a second umbrella rib 313 rotatably mounted on the middle of the first umbrella rib 312, a sleeve 314 rotatably mounted on one end of the second umbrella rib 313, a locking block 315 movably mounted inside the sleeve 314, a spring 316 fixedly connected to one side of the locking block 315, the top seat 311 fixedly mounted on the top of the umbrella handle 2, the sleeve 314 sleeved between the umbrella handle 2, the locking block 315 movably mounted inside the umbrella handle 2, one end of the locking block 315 passing through the umbrella handle 2 and the sleeve 314 in sequence, and one end of the locking block 315 extending to the outside of the sleeve 314, one end of the spring 316 fixedly connected to the inner wall of the umbrella handle 2, one end of the first umbrella rib 312 fixedly mounted to the inner layer 323, and the top seat 311 fixedly mounted to the outer layer 321 and the inner layer 323 respectively.

[0035] Working principle: Umbrella rib 312 is fixedly installed with the inner layer 321. One end of umbrella rib 312 is rotatably installed with the top seat 311. Umbrella rib 313 is rotatably installed in the middle of umbrella rib 312. One end of umbrella rib 313 is rotatably installed with the sleeve 314. When the sleeve 314 slides on the surface of the umbrella handle 2, the umbrella surface 1 will retract and open. When the umbrella surface 1 is opened, the locking block 315 limits the sleeve 314. When the locking block 315 is pressed, the spring 316 retracts, and the umbrella surface 1 retracts. Then the umbrella surface 1 can be tied and gathered using the gathering strap 5.

[0036] The umbrella surface 1 is a titanium dioxide nano-coating with a thickness controlled between 50-100μm. This type of coating is non-flammable and forms a dense glaze layer at high temperatures, further blocking oxygen from contacting the flame. It also reflects some heat radiation, with a reflectivity of over 60%, reducing the heat absorbed by the fabric. In addition, the coating can fill the tiny pores on the fabric surface, reducing the efficiency of heat convection through the pores.

[0037] The outer layer 321 is made of high-density woven fabric with a warp and weft density of ≥300 threads / inch. The tight fiber arrangement blocks the direct penetration of flames and reduces heat radiation conduction. The inner layer 323 is made of fluffy nonwoven fabric. It uses a large number of closed pores between fibers to store still air and reduces heat transfer efficiency by increasing the heat conduction path.

[0038] The outer layer 321 and the inner layer 323 together form a high-silica fireproof and heat-insulating cloth. An aluminum foil film 322 with a thickness of ≤10μm is laminated on the surface of the inner layer 323. Utilizing the high reflectivity of metal, the aluminum foil has a reflectivity of more than 90% for infrared heat radiation, which reflects the heat radiation in the high-temperature environment back and reduces the heat transfer to the protected side. The metal layer needs to be laminated with the inner layer 323 through a high-temperature resistant adhesive (such as silicone rubber adhesive) to avoid peeling at high temperatures. At the same time, the ductility of the metal layer can buffer the brittleness of the high-silica fiber and improve the overall flexibility.

[0039] Example 2:

[0040] Based on Embodiment 1, a warning component 4 is provided inside the umbrella handle 2;

[0041] The warning component 4 includes a warning part 41 and a switch part 42, both of which are located inside the umbrella handle 2.

[0042] The warning part 41 includes a protective cover 411, a miniature temperature sensor 412 is provided at the bottom of the protective cover 411, a flashing ring light 413 is fixedly installed at one end of the umbrella handle 2 near the top, the protective cover 411 is fixedly installed on the top of the top seat 311, the miniature temperature sensor 412 is fixedly installed inside the top seat 311, and the miniature temperature sensor 412 is electrically connected to the flashing ring light 413.

[0043] The switch part 42 includes a power block 421. A cover 422 is fixedly installed at one end of the umbrella handle 2 near the top. A switch 423 is provided in the middle of the cover 422. The power block 421 is fixedly installed inside the umbrella handle 2. The power block 421 is electrically connected to the switch 423 and the flashing ring light 413 respectively.

[0044] Working principle: The miniature temperature sensor 412 can be equipped with the Raytek RAYMI3100, which is the high-temperature sensor head of the Raytek MI3 two-piece infrared temperature measurement system. It has two temperature ranges: 500-1800℃ and 250-1400℃. It features a fast response (10mSec), 1.0 and 1.6μm spectral response sensor and a laser vision 100:1 optics.

[0045] Switch 423 controls the start and stop of the main circuit. When switch 423 is turned on, power block 421 continuously supplies power and the main circuit is powered on. When the temperature detected by miniature temperature sensor 412 is below the preset temperature, the flashing ring light 413 is always on. If the temperature exceeds the preset temperature (e.g., 1000℃), the flashing ring light 413 will flash to remind the user to stay away from the high temperature area.
