Description

Technical Field

[0001] The present invention relates to the technical field of oil fume sensors, and in particular to an oil fume gas sensor that can be easily installed. Background Art

[0002] A fume gas sensor is an electronic device designed to detect specific gas components (such as combustible gases, carbon monoxide, carbon dioxide, and volatile organic compounds). Typically based on sensing technologies such as semiconductors, electrochemical sensors, or catalytic combustion sensors, it monitors gas concentrations in the environment in real time and issues an alarm when safety thresholds are exceeded to prevent fires or health hazards. These sensors are commonly used in industrial kitchens, large supermarkets, and factories.

[0003] In large supermarkets, a suspended conveyor system or suspended logistics conveyor line is typically installed beneath the ceiling. This type of system is primarily used for warehouse management and cargo sorting operations to improve work efficiency, reduce manual handling costs, and optimize space utilization. It primarily consists of a track system, drive unit, cargo trolley, and control system. By conveniently mounting the fume and gas sensor material magnetically or with bolts beneath the trolley, the trolley's movement allows for dynamic monitoring of the gas environment within the supermarket. During specific time periods or under special conditions (such as during a failure of fixed monitoring equipment), resources can be concentrated on monitoring key areas, improving problem detection and resolution efficiency.

[0004] However, due to the high humidity in the aquatic area of ​​the supermarket, moisture not only affects the response time and accuracy of the sensor, but may also cause condensation on the sensor surface, thereby affecting long-term stability. Existing oil fume gas sensors are not convenient to reduce the moisture in the gas before detection, resulting in longer sensor response time and reduced accuracy, making it difficult to meet usage requirements. Summary of the Invention

[0009] In order to prevent the gas from flowing directly into the detection chamber through the channel, a baffle is further fixedly provided below the channel entrance through a plurality of connecting rods, and the diameter of the baffle is larger than the inner diameter of the channel.

[0010] In order to facilitate the extraction of external gas, a fixed shaft is further fixedly provided at the bottom of the baffle, and a plurality of wind blades evenly distributed in a circle are fixedly provided at one end of the fixed shaft extending into the first air inlet cylinder. When the fixed shaft rotates, the wind blades inhale gas from the outside through the first air inlet cylinder.

[0011] Furthermore, a rotation groove is provided on the inner wall of the filter cartridge, and a mounting frame is fixedly provided on the filter screen, and the mounting frame is rotatably connected in the rotation groove.

[0012] Furthermore, at least one group of fan-shaped cleaning boxes is fixedly provided on the inner wall of the filter cartridge, an avoidance groove is provided on the cleaning box, the filter screen passes through the avoidance groove and is rotatably provided in the cleaning box, and a collecting box is removably provided in the cleaning box, a slot is provided on the top of the collecting box, a cleaning plate is slidably provided in the slot, a brush is fixedly provided on the top of the cleaning plate, and the brush is against the air inlet end of the filter screen.

[0014] Preferably, the driving part includes a rotating shaft rotatably arranged on the outer shell, a fourth gear is fixedly arranged at one end of the rotating shaft, the fourth gear is meshed with the outer wall of the rotating seat, and a fifth gear and a sixth gear are respectively arranged at the other end of the rotating shaft through one-way bearings, the fifth gear and the sixth gear are distributed up and down along the axis of the rotating shaft, a sliding groove is provided at the bottom of the track, and a first rack and a second rack are fixedly arranged on the inner walls on both sides of the sliding groove, the fifth gear is meshed with the first rack, and the sixth gear is meshed with the second rack, and the two groups of one-way bearings are in opposite directions.

When the gas flows from the channel to the exhaust hole, it just passes through the detection end of the detection part.

[0017] Compared with the prior art, the present invention provides a fume gas sensor that can be easily installed and has the following beneficial effects:

[0018] 1. This conveniently installed oil fume gas sensor features a rotating base that rotates within the housing, with a mesh-covered separation cylinder fixed to its bottom. When the trolley slides and carries the housing to transport goods, the rotating base and separation cylinder rotate, utilizing centrifugal force to separate heavier water droplets from the airflow, minimizing the moisture content in the gas. This can largely eliminate the impact of moisture in the smoke on the oil fume sensor, ensuring it consistently provides accurate and reliable monitoring data.

[0019] 2. This oil fume gas sensor, which can be easily installed, has a baffle fixed below the channel entrance to prevent the gas entering from the second air inlet from flowing directly into the channel. This not only prolongs the gas's residence time in the separation cylinder, but also reduces the gas flow rate due to the baffle, helping to precipitate moisture in the gas and improving its performance.

[0020] 3. The oil fume gas sensor can be easily installed. A fan-shaped cleaning box is fixedly arranged in the filter cartridge, a collection box is removed and arranged in the cleaning box, and a cleaning plate is plugged into the collection box. A brush is fixed on the cleaning plate. During the rotation of the filter, the brush can clean the part of the filter located in the cleaning box, thereby reducing particulate matter on the filter and ensuring the ventilation effect of the filter. The dust swept down will settle in the collection box. During subsequent maintenance, the collection box and the brush can be removed for cleaning to improve the use effect.

[0021] The parts not involved in this device are the same as the existing technology or can be implemented by using existing technology. The present invention has a rotating seat that is rotatable in the outer shell, and a separation cylinder with a mesh is fixedly set at the bottom of the rotating seat. Centrifugal force can be used to separate heavier water droplets from the air flow, thereby minimizing the moisture content in the gas. The influence of moisture in the flue gas on the oil fume sensor can be eliminated to a large extent, ensuring that it always provides accurate and reliable monitoring data.

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0031] Example:

[0032] Reference Figures 1-6, a fume gas sensor that can be easily installed, including a shell 1 installed on a cargo trolley 901, the cargo trolley 901 has its own power device, and a hook is provided at the bottom for hanging baskets or other containers to facilitate the transportation and distribution of goods. A plurality of fixing ears are fixedly provided on the top of the shell 1, and there are two to eight fixing ears. Here, we prefer four, and they are evenly distributed around the circumference. Through holes are provided on the fixing ears, which can be fixed to the bottom of the cargo trolley 901 by screws, and the air inlet end of the shell 1 is set downward. A detection part 103 is provided in the shell 1, and the detection part 103 adopts a photoelectric or ion type. Here, we prefer a photoelectric type. The principle is to use infrared light scattering technology to detect smoke particles. When smoke enters the detection cavity, the light is scattered to trigger an alarm, and the power supply method of the detection part 103 is a rechargeable battery or AC power. Here, we prefer the same power supply method as the cargo trolley 901, that is, AC power.The invention also includes: a rotating seat 2 with a rotating disc structure, a separation chamber 102 is provided in the shell 1, the rotating seat 2 is rotatably connected in the separation chamber 102, a separation cylinder 201 with a mesh is fixedly provided at the bottom of the rotating seat 2, a second air inlet cylinder 202 is fixedly provided at the bottom of the separation cylinder 201, the second air inlet cylinder 202 is in a bell-shaped structure, and the small end of the bell-shaped extends into the separation cylinder 201, a channel 203 is provided at the top of the rotating seat 2, the detection end of the detection unit 103 is arranged above the outlet of the channel 203, and a driving unit for driving the rotating seat 2 to rotate is provided in the shell 1. During use, the driving unit is started to rotate the rotating seat 2 and the separation cylinder 201. After the gas passes through the second air inlet cylinder 202 and enters the separation cylinder 201, the centrifugal force is used to separate the heavier water droplets from the air flow, thereby reducing the moisture content in the gas as much as possible. This can largely eliminate the influence of moisture in the flue gas on the oil fume sensor, ensuring that it always provides accurate and reliable monitoring data. The separated gas is discharged to the detection end of the detection unit 103 through the channel 203, and the detection unit 103 can perform detection, while the water flow thrown out flows along the inner wall of the separation chamber 102 to the bottom thereof. In order to facilitate the discharge of the collected water to the outside, a drain pipe with a valve is fixed on the shell 1, and the water inlet end of the drain pipe is connected to the bottom of the separation chamber 102. When draining, the hose is put on the outlet of the drain pipe, and then the valve is opened. The water collected at the bottom of the separation chamber 102 can be discharged to a designated location or container through the drain pipe and the hose, thereby improving the use effect. A detection chamber 101 is opened in the shell 1, and the top of the separation chamber 102 is connected to the bottom of the detection chamber 101, that is, the detection chamber 101 is located at the top of the separation chamber 102, and the detection part 103 is connected to the detection part 103. It is fixedly arranged in the detection chamber 101, and an exhaust hole 105 coaxial with the channel 203 is opened at the top of the detection chamber 101, and a protective net is fixedly arranged in the exhaust hole 105. When the gas flows from the channel 203 to the exhaust hole 105, it just passes through the detection end of the detection part 103, which is convenient for detecting the gas composition; a filter cartridge 3 is fixedly arranged at the bottom of the outer shell 1, and the filter cartridge 3 is located below the second air inlet cylinder 202. A filter net 4 is arranged in the filter cartridge 3, which can filter the gas entering the separation chamber 102, reduce solid particles in the gas, and improve the use effect.

[0033] During use, a rotating seat 2 is rotated in the outer shell 1, and a separation cylinder 201 with a mesh is fixedly set at the bottom of the rotating seat 2. When the cargo trolley 901 slides and carries the outer shell 1 to transport goods, the rotating seat 2 and the separation cylinder 201 rotate, and the centrifugal force can be used to separate heavier water droplets from the air flow, thereby minimizing the moisture content in the gas. This can largely eliminate the influence of moisture in the flue gas on the oil fume sensor, ensuring that it always provides accurate and reliable monitoring data.

[0034] Reference Figure 5A first air inlet cylinder 104 in the shape of a trumpet is fixedly provided at the bottom of the separation chamber 102, and the small end of the first air inlet cylinder 104 in the shape of a trumpet extends into the separation cylinder 201, and the second air inlet cylinder 202 is sleeved on the outside of the first air inlet cylinder 104, and a sealing ring is provided on the outer wall of the first air inlet cylinder 104, and the end face of the sealing ring away from the first air inlet cylinder 104 is abutted against the inner wall of the second air inlet cylinder 202, and the filter cylinder 3 is fixedly provided at the air inlet end of the first air inlet cylinder 104. When in use, by setting the filter cylinder 3 at the air inlet end of the first air inlet cylinder 104, the incoming gas can be filtered to reduce solid particles in the gas, and the second air inlet cylinder 202 is sleeved on the outside of the first air inlet cylinder 104 to facilitate the gas to enter the separation cylinder 201.

[0035] Reference Figure 5 A baffle 204 is fixedly provided below the entrance of the channel 203 through multiple connecting rods. There are two to six connecting rods. Here, we prefer four. The four connecting rods are evenly distributed around the circumference, and the diameter of the baffle 204 is larger than the inner diameter of the channel 203. When in use, by fixing the baffle 204 below the entrance of the channel 203, the gas entering from the second air inlet cylinder 202 can be prevented from flowing directly into the channel 203, which not only prolongs the residence time of the gas in the separation cylinder 201, but also reduces the gas flow rate under the obstruction of the baffle 204, which helps to precipitate the moisture in the gas and improves the use effect.

[0036] Reference Figure 5 A fixed shaft 205 is fixedly provided at the bottom of the baffle 204, and a plurality of wind blades 207 uniformly distributed in a circle are fixedly provided at one end of the fixed shaft 205 extending into the first air inlet cylinder 104. There are two to ten wind blades 207. Here, we prefer five. When the fixed shaft 205 rotates, the wind blades 207 inhale gas from the outside through the first air inlet cylinder 104. When in use, when the separation cylinder 201 is rotated with the rotating seat 2 to separate the moisture in the gas, the fixed shaft 205 and the wind blades 207 can be rotated at the same time, and then the gas is inhaled from the outside through the first air inlet cylinder 104 and the second air inlet cylinder 202, and the gas is sent to the separation cylinder 201, which is convenient for detecting the gas along the way and improving the use effect.

[0037] Reference Figure 3-Figure 6A rotating groove 301 is provided on the inner wall of the filter cartridge 3. The rotating groove 301 is a circular ring structure. A mounting frame 401 is fixedly provided on the filter screen 4. The mounting frame 401 is rotatably connected in the rotating groove 301. The mounting frame 401 includes an inner disc and an outer ring. The outer ring is rotatably connected in the rotating groove 301. When in use, by opening the rotating groove 301 in the filter cartridge 3 and rotatably connecting the mounting frame 401 in the rotating groove 301, not only can the position of the filter screen 4 be guaranteed, but also the filter screen 4 can be easily rotated around its axis, which is convenient for subsequent operations.

[0038] Reference Figure 2-Figure 6 The filter screen 4 is rotated in the cleaning box 5 through the avoidance groove, that is, when the filter screen 4 rotates around its axis, the filter screen 4 can be swept through the cleaning box 5, and a collection box 6 is removably arranged in the cleaning box 5. In this case, the bottom of the cleaning box 5 is designed to be open, and the collection box 6 is slid from bottom to top and arranged in the cleaning box 5. In order to prevent the collection box 6 from falling, the collection box 6 is fixedly connected to the cleaning box 5 by bolts, buckles or magnetic attraction, preferably magnetic attraction, that is, a first magnetic block is fixedly provided on the bottom end surface of the cleaning box 5, and a second magnetic block corresponding to the first magnetic block is fixedly provided on the collection box 6, and the first magnetic block is magnetically attracted to the second magnetic block to achieve the collection box 6 being fixed. The cleaning plate 7 is fixed on the cleaning plate 7, which is convenient for assembly and disassembly and reliable for fixing, so as to facilitate the processing of the dust collected in the collection box 6 and improve the use effect. A slot 601 is provided on the top of the collection box 6, and a cleaning plate 7 is slidably provided in the slot 601. A brush 701 is fixed on the top of the cleaning plate 7, and the brush 701 is pressed against the air inlet end of the filter screen 4. When in use, the cleaning box 5 with a fan-shaped structure is fixedly provided in the filter cylinder 3, the collection box 6 is disassembled and set in the cleaning box 5, and the cleaning plate 7 is plugged into the collection box 6, and the brush 701 is fixed on the cleaning plate 7. During the rotation of the filter screen 4, the brush 701 can clean a part of the filter screen 4 located in the cleaning box 5, reduce the particulate matter on the filter screen 4, ensure the ventilation effect of the filter screen 4, and the swept dust will be deposited in the collection box 6, so that the collection box 6 and the brush 701 can be removed for cleaning in subsequent maintenance, thereby improving the use effect.

[0039] Reference Figure 3 、 Figure 5 and Figure 6A connecting plate is fixedly provided on the outer wall of the cleaning box 5, and a connecting shaft 501 is rotatably provided on the connecting plate. A second gear 502 and a third gear 503 are fixedly provided at both ends of the connecting shaft 501. An intermittent gear 206 is fixedly provided at one end of the fixed shaft 205 extending into the filter cylinder 3. The intermittent gear 206 is also called an incomplete gear. Here, it is preferred that the intermittent gear 206 is preferably one tenth of a normal gear. The speed of the separation cylinder 201 is generally between 300 and 5000 rpm. The specific value depends on the actual working conditions. Here, we prefer 800 rpm. The second gear 50 2 is meshed with the intermittent gear 206, and a first gear 402 is fixedly provided on the top of the mounting frame 401 and is meshed with the third gear 503. The diameter of the first gear 402 is larger than the diameter of the third gear 503, which is two to five times, preferably four times, so as to make the filter 4 rotate at a lower speed. When in use, when the rotating seat 2 rotates with the fixed shaft 205, the filter 4 can be driven to rotate through a series of reduction transmissions. During the rotation process, the brush 701 can clean a part of the filter 4 located in the cleaning box 5, thereby reducing particulate matter on the filter 4 and ensuring the ventilation effect of the filter 4.

[0040] Reference Figure 1 、 Figure 4 and Figure 5 The driving unit can use a servo motor to drive the rotating seat 2 to rotate. Here, according to actual usage, we design the driving unit to be rotatably provided with a rotating shaft 8 on the shell 1, and a fourth gear 801 is fixedly provided at one end of the rotating shaft 8, and the fourth gear 801 is meshed with the outer wall of the rotating seat 2, and the other end of the rotating shaft 8 is respectively provided with a fifth gear 802 and a sixth gear 803 through a one-way bearing. The one-way bearing is a prior art. The fifth gear 802 and the sixth gear 803 are distributed up and down along the axis direction of the rotating shaft 8. A slide groove is provided at the bottom of the track 9, and a first rack and a second rack are fixedly provided on the inner walls on both sides of the slide groove. The first rack and the second rack are also distributed up and down in the axis direction of the rotating shaft 8, and the fifth gear 802 is meshed with the first rack. The sixth gear 803 is meshed with the second rack, and the two sets of one-way bearings are in opposite directions. During use, when the loading trolley 901 slides along the track 9 from one end to the other end with the shell 1, the fifth gear 802 rotates on the first rack, and can drive the rotating shaft 8 to rotate in one direction through the one-way bearing matched therewith. At this time, the sixth gear 803 is in an idling state. Conversely, when the loading trolley 901 returns along the track 9 with the shell 1, the fifth gear 802 is in an idling state, and the sixth gear 803 can drive the rotating shaft 8 to rotate in the previous rotation direction through the one-way bearing matched therewith. That is to say, when the loading trolley 901 slides along the track 9 from one end to the other end or returns with the shell 1, the rotation direction of the rotating shaft 8 is consistent, thereby improving the use effect.
