Description

Technical Field

[0001] This utility model relates to the field of smoke detectors, and more particularly to a smoke detector with high intensity of use. Background Technology

[0002] Smoke detectors, also known as smoke-sensing fire detectors, smoke detectors, smoke probes, and smoke sensors, are mainly used in fire protection systems and are also used in security system construction. Smoke detectors are important equipment to ensure fire safety and are widely used in places with dense populations or concentrated materials, such as industrial plants, warehouses, and shopping malls.

[0003] Traditional smoke detectors have limited structural strength, making them prone to problems such as shell cracking and deformation during routine maintenance, equipment handling, or accidental impacts. This can lead to damage to the internal precision sensing elements, resulting in decreased detection accuracy, false alarms, missed alarms, or even complete failure, thus increasing the maintenance costs of the equipment.

[0004] Therefore, it is necessary to provide a smoke sensor with high intensity to solve the above-mentioned technical problems. The information disclosed in this background section is only intended to enhance the understanding of the overall background of this utility model, and is not necessarily to be regarded as an admission or to imply in any way that the information constitutes prior art that has become known to those skilled in the art. Utility Model Content

[0005] This invention provides a high-strength smoke sensor, which solves the technical problem that smoke sensors have limited structural strength and are prone to cracking and deformation of the outer shell during daily maintenance, equipment handling, or accidental impacts. This leads to exposure and damage of the internal precision sensing elements, resulting in decreased detection accuracy, false alarms, missed alarms, or even complete failure, thus increasing equipment maintenance costs.

[0006] To solve the above-mentioned technical problems, this utility model provides a high-strength smoke sensor, including a sensor body, a smoke detection component installed at the upper end of the sensor body, a protective shell, and a maintenance bottom cover mounted on the bottom of the protective shell by screws. The protective shell includes a reinforcing base, a fiber reinforcement layer, and a wear-resistant outer layer. The reinforcing base is disposed on the inner surface of the fiber reinforcement layer, and the fiber reinforcement layer is disposed on the inner surface of the wear-resistant outer layer. The reinforcing base includes a polypropylene layer and a plastic alloy material layer. The polypropylene layer is disposed on the inner surface of the plastic alloy material layer. The fiber reinforcement layer includes a glass fiber layer, an epoxy resin layer, and a polycarbonate layer. The glass fiber layer is disposed on the inner surface of the epoxy resin layer, and the epoxy resin layer is disposed on the inner surface of the polycarbonate layer.

[0007] Preferably, a sealing gasket is provided at the connection between the upper end of the maintenance cover and the lower end of the protective shell, and heat dissipation vents are sequentially opened on the outer surface of the protective shell from top to bottom, and heat dissipation filters are provided in the inner cavity of the heat dissipation vents.

[0008] Preferably, the outer surface of the smoke detection component is provided with a smoke inlet, and buzzers are provided on both sides of the upper end of the smoke detection component.

[0009] Preferably, an indicator light is provided on the front side of the upper end of the smoke detection component.

[0010] Preferably, a test button is provided on the front side of the upper left side of the sensor body, and a switch button is provided on the rear side of the upper left side of the sensor body.

[0011] Preferably, the smoke detection component and the sensor body are integrally formed, and the material of the sensor body is the same as that of the protective shell.

[0012] Compared with related technologies, the smoke sensor with high operating strength provided by this utility model has the following beneficial effects:

[0013] This utility model provides a high-strength smoke sensor. During routine maintenance, the internal module can be inspected by disassembling the inspection cover at the bottom of the protective shell. The sealing gasket reduces frictional wear between components during disassembly and assembly, while preventing dust from entering through gaps. The multi-layered high-strength structure of the protective shell resists external impacts and vibrations, while the heat dissipation vents and heat dissipation filters ensure the heat dissipation efficiency of the internal module in high-temperature environments, avoiding overheating that could affect operational stability. The protective system formed by the reinforced base layer, fiber reinforcement layer, and wear-resistant outer layer provides continuous protection for the long-term stable operation of the equipment in complex environments.

[0014] This utility model provides a high-intensity smoke sensor. When the device is running, external smoke enters the detection chamber through the smoke inlet on the outer surface of the smoke detection component. The internal sensing element, such as a photoelectric sensor, senses the change in smoke concentration and converts it into an electrical signal, which is transmitted to the control module inside the sensor body. The control module analyzes the signal, and when the concentration exceeds the threshold, it drives the buzzers on both sides of the upper end of the smoke detection component to emit an alarm sound. At the same time, it controls the indicator light on the front to flash at a high frequency, realizing a synchronized sound and light warning.

[0015] This utility model provides a high-strength smoke sensor. Users can perform a self-test using the test button on the upper left side of the sensor body. The switch button is used for device start-stop control. During operation, the button structure is reinforced to ensure reliability under frequent use. Smoke sensors are existing technology and will not be described in detail here. The contents not described in detail in this specification are existing technologies known to those skilled in the art. Their technical principles and implementation methods are within the general knowledge scope of those skilled in the art. To keep the specification concise, basic technical details will not be repeated here. The focus is on describing the innovative improvements of this technology. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1:

[0024] Please see Figure 1-5This utility model provides a technical solution: a high-strength smoke sensor, including a sensor body 1, a smoke detection component 2 installed at the upper end of the sensor body 1, a protective shell 3, and a maintenance bottom cover 4 installed at the bottom of the protective shell 3 by screws. The protective shell 3 includes a reinforcing base layer 5, a fiber reinforcement layer 6, and a wear-resistant outer layer 7. The reinforcing base layer 5 is disposed on the inner surface of the fiber reinforcement layer 6, and the fiber reinforcement layer 6 is disposed on the inner surface of the wear-resistant outer layer 7. The reinforcing base layer 5 includes a polypropylene layer 51 and a plastic alloy material layer 52. The polypropylene layer 51 is disposed on the inner surface of the plastic alloy material layer 52. The fiber reinforcement layer 6 includes a glass fiber layer 61, an epoxy resin layer 62, and a polycarbonate layer 63. The glass fiber layer 61 is disposed on the inner surface of the epoxy resin layer 62, and the epoxy resin layer 62 is disposed on the inner surface of the polycarbonate layer 63.

[0025] In this embodiment, the protective shell 3 adopts a composite structure of "reinforced base layer 5, fiber reinforcement layer 6, and wear-resistant outer layer 7". Each layer works together to build a high-strength protective system. The polypropylene layer 51 of the reinforced base layer 5 and the plastic alloy material layer 52 form a gradient support. The polypropylene layer 51 has good toughness and formability, while the plastic alloy material layer 52 improves rigidity and impact resistance through alloying modification, providing solid internal support for the protective shell 3. In the fiber reinforcement layer 6, the glass fiber layer 61 enhances the overall tensile strength with its high strength characteristics. The epoxy resin layer 62 serves as a bonding matrix to tightly bond the glass fiber layer 61 and the polycarbonate layer 63. The polycarbonate layer 63 further improves the bending resistance of the structure. The three-layer composite improves the impact resistance of the protective shell 3 compared to traditional structures. The wear-resistant outer layer 7 effectively resists daily friction and dust erosion, extending the service life of the protective shell 3.

[0026] Example 2:

[0027] Please see Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: a sealing gasket is provided at the connection between the upper end of the inspection base 4 and the lower end of the protective shell 3; heat dissipation vents are sequentially opened from top to bottom on the outer surface of the protective shell 3, and a heat dissipation filter is provided in the inner cavity of the heat dissipation vents; a smoke inlet 8 is opened on the outer surface of the smoke detection component 2; buzzers are provided on both sides of the upper end of the smoke detection component 2; an indicator light is provided on the front side of the upper end of the smoke detection component 2; a test button is provided on the front side of the upper left side of the sensor body 1; a switch button is provided on the rear side of the upper left side of the sensor body 1; the smoke detection component 2 and the sensor body 1 are integrally formed; and the material of the sensor body 1 is the same as that of the protective shell 3.

[0028] In this embodiment: the smoke detection component 2 and the sensor body 1 are integrally molded, eliminating the strength deficiency caused by the connection gap, ensuring that the detection component is subjected to force synchronously with the body when subjected to external force, avoiding local breakage. The connection between the maintenance bottom cover 4 and the protective shell 3 is equipped with a sealing gasket, which not only improves the sealing performance, but also reduces the stress concentration at the screw connection through elastic buffering, reducing the risk of thread wear caused by frequent disassembly and assembly. The heat dissipation vents on the outer surface of the protective shell 3 are combined with a heat dissipation filter. While ensuring heat dissipation efficiency, the mesh structure of the filter forms an auxiliary support for the protective shell 3, enhancing the local anti-deformation ability.

[0029] The working principle of the high-intensity smoke detector provided by this utility model is as follows:

[0030] Implementation steps for the first innovation point:

[0031] Step 1: The protective shell 3 adopts a composite structure of "reinforced base layer 5, fiber reinforcement layer 6 and wear-resistant outer layer 7". Each layer works together to build a high-strength protective system. The polypropylene layer 51 of the reinforced base layer 5 and the plastic alloy material layer 52 form a gradient support. The polypropylene layer 51 has good toughness and formability.

[0032] The second step: the plastic alloy material layer 52 improves rigidity and impact resistance through alloying modification, providing solid internal support for the protective shell 3. In the fiber reinforcement layer 6, the glass fiber layer 61 enhances the overall tensile strength with its high strength characteristics.

[0033] Step 3: The epoxy resin layer 62 serves as the bonding matrix to tightly bond the glass fiber layer 61 and the polycarbonate layer 63. The polycarbonate layer 63 further enhances the bending resistance of the structure. The three-layer composite improves the impact resistance of the protective shell 3 compared to the traditional structure. The wear-resistant outer layer 7 effectively resists daily friction and dust erosion, extending the service life of the protective shell 3.

[0034] Implementation steps for the second innovation point:

[0035] Step 1: The smoke detection component 2 and the sensor body 1 are made of one piece, which eliminates the weakness caused by the connection gap and ensures that the detection component is subjected to the force synchronously with the body when subjected to external force, thus avoiding local breakage.

[0036] Step 2: Install a sealing gasket at the connection between the bottom cover 4 and the protective shell 3. This not only improves the sealing performance but also reduces stress concentration at the screw connection through elastic buffering, thereby reducing the risk of thread wear caused by frequent disassembly and assembly. The heat dissipation vents on the outer surface of the protective shell 3, together with the heat dissipation filter, ensure heat dissipation efficiency while the mesh structure of the filter provides auxiliary support for the protective shell 3, enhancing its local resistance to deformation.
