Description

Technical Field

[0001] This utility model relates to the field of heating devices, and in particular to a photoelectric sensor bracket with anti-light leakage and anti-dust functions. Background Technology

[0002] Photoelectric sensor components are commonly used in fuel-fired heaters. The photoelectric sensor in the component is used to detect whether the fuel-fired heater is still working. If it is not working, the photoelectric sensor will transmit a signal and automatically shut down the machine after not detecting a light source.

[0003] However, some existing fuel-fired heaters lack baffles or other dust and light protection structures at the front of their photoelectric sensors or detection units. In such cases, even when external light shines in, the ignition or detection unit will still detect the light, and the heater will continue to operate. Prolonged operation under these conditions can damage the internal structure and affect usability. Furthermore, when operating outdoors, dust or other particulate matter can blow onto the front of the photoelectric sensor or detection unit, blocking it. This prevents the sensor or detection unit from sensing light, causing it to shut down and affecting user experience and potentially damaging internal components. Utility Model Content

[0032] like Figures 1 to 3As shown, this utility model provides

[0033] A photoelectric sensor bracket with light leakage prevention and dust prevention functions includes a bracket body 1, wherein the bracket body 1 includes: a housing 2; a baffle 3 disposed within the housing 2; and a detection unit 4, one end of which is disposed within the housing 2, and the other end of which is electrically connected to internal components of the machine; the baffle 3 is disposed at the front end of the detection unit 4. By setting the baffle 3 and the housing 2 at the front end of the detection unit 4, the housing 2 serves to prevent light leakage, and the baffle 3 serves to prevent dust, thus preventing smoke generated during machine operation or external light sources from affecting the detection unit 4.

[0034] The outer shell 2 has a hollow structure; an inner fixing seat 21 is provided inside the outer shell 2; an outer fixing seat 22 is provided at one end of the outer shell 2. The outer fixing seat 22 is provided to facilitate the fixing of the outer shell 2 to the machine; the inner fixing seat 21 is provided to facilitate the placement of the baffle 3 inside the outer shell 2.

[0035] The baffle 3 is mounted on the inner fixing seat 21; the diameter of the baffle 3 is not less than the diameter of the inner fixing seat 21. By setting the inner fixing seat 21 and ensuring that the diameter of the baffle 3 is not less than the diameter of the inner fixing seat 21, the baffle 3 will not fall off or shift when mounted inside the outer casing 2, thus affecting its use.

[0036] The external fixing seat 22 is provided with at least one mounting hole 23; by providing mounting holes 23 on the external fixing seat 22, the bracket body 1 can be installed on the machine without loosening, thus improving the stability of the structure.

[0037] The detection unit 4 includes any one of photoresistors, photosensors, etc. Multiple detection units 4 are provided to allow users to choose the appropriate one for different usage scenarios.

[0038] The baffle 3 can be any one of glass baffle 3, plastic baffle 3, or iron baffle 3. Multiple baffles 3 are provided to allow users to choose the appropriate one for different usage scenarios.

[0039] In this embodiment:

[0040] When a user is using a fuel-fired heater, the internal detection unit 4 detects that light is present inside and the heater is operating. Therefore, the detection unit 4 will not shut down the machine. Due to varying environmental conditions, the external environment can affect the detection unit 4. In this case, the outer casing 2 and the baffle 3 will act as dust and light protectors. When the machine is finished using and the detection unit 4 detects that there is no light inside, it will transmit a signal to the internal components to shut down the machine and prevent damage to the internal parts, as the detection unit 4 is electrically connected to the internal components.

[0041] The detection unit 4 is equipped with pins for electrical connection with the internal components of the fuel heater. The pins are shown in the figure. The structure and connection method of the component are conventional and well-known to those skilled in the art, so there is no need for further description or illustration.

[0042] The working principle of a photoresistor is based on the internal photoelectric effect. Electrode leads are attached to both ends of a semiconductor photosensitive material, and the material is encapsulated in a tube with a transparent window, thus forming a photoresistor. Photoresistors are highly sensitive to light. When exposed to light, the resistance of the photoresistor decreases rapidly. Specifically, the stronger the light, the lower the resistance. This is because light causes electrons in the semiconductor material to absorb photon energy and jump to the conduction band, generating positively charged holes in the valence band. These electrons and holes increase the number of charge carriers in the semiconductor material, thereby reducing its resistivity.

[0043] The working principle of a photoelectric sensor is mainly based on the photoelectric effect, which means that when light shines on an object, the electrons in the object absorb the energy of the photons, resulting in an electrical effect. A photoelectric sensor typically consists of three parts: a transmitter, a receiver, and a detection circuit. The transmitter emits a light beam, usually using a semiconductor light source such as a light-emitting diode (LED), laser diode, or infrared emitting diode. The receiver, composed of a photodiode, phototransistor, or photovoltaic cell, captures the light signal and converts it into an electrical signal; it processes the received electrical signal, filters out noise and interference, extracts the useful signal, and converts it into a control signal or data output.
