Description

Technical Field

[0001] The utility model relates to the technical field of gas appliance accessories, and particularly relates to an ODS structure with adjustable gas source. Background Art

[0002] In gas equipment, the ODS (Oxygen Detection Safety) system is an important safety component, which is used to ensure that the equipment operates in an environment with sufficient oxygen and prevent incomplete combustion or safety hazards caused by insufficient oxygen.

[0003] Gas stoves are kitchen appliances often used in daily life. Since gas is a flammable substance, people must be highly vigilant about the safety issues of gas stoves. Gas stoves are designed with different parameters according to the calorific value of the gas used. In China, there are generally three types: artificial gas, natural gas, and liquefied petroleum gas. In some areas, there are also water gas, liquefied gas mixed with air, coke oven gas, etc., but they are relatively rare. Since there is no unified gas source standard in China and the gas source composition varies from place to place, the types of gas sources are numerous. Currently, due to different gas sources in different regions, the types of gas stoves will also be different. Different gas sources have different pressures, so it is necessary to distinguish which gas source of gas stove to buy when purchasing. However, there are still some problems. For example, in some areas, natural gas supply has not been popularized, and liquefied petroleum gas is still used. Therefore, a gas stove corresponding to liquefied petroleum gas is purchased. But after a period of time, natural gas supply is realized. At this time, people can only choose to buy a new gas stove, and the original liquefied gas cylinder and stove are left unused, thus greatly increasing people's expenses.

[0004] To solve the above problems, a Chinese patent with the application number 201811192704.8 discloses a dual-gas-type switching valve. The disclosed switching valve includes a valve body. The valve body is provided with a conical valve cavity. A conical valve core is arranged in the conical valve cavity. A valve core hole is arranged in the middle of the valve core. One end of the valve core is provided with a rotating shaft extending out of the valve body. The valve body is provided with an external dual-gas source channel, a nozzle air inlet channel and a pilot flame air inlet channel. The valve body is also provided with an A gas source outlet channel, a B gas source outlet channel, a nozzle outlet channel, and a pilot flame A gas source outlet channel and a pilot flame B gas source outlet channel. The valve core is provided with a first valve core channel connecting the external dual-gas source channel with the A gas source outlet channel and the B gas source outlet channel, a second valve core channel connecting the nozzle air inlet channel with the nozzle outlet channel, and a third valve core channel connecting the pilot flame air inlet channel with the pilot flame A gas source outlet channel and the B gas source outlet channel. A Chinese patent with the application number 201510366346.8 discloses a dual-gas-source gas conversion valve device. The disclosed conversion valve device includes a valve body, an air inlet hole and an air outlet hole for the dual-gas source to enter and exit, and a valve core with a handle. One end of the valve body is provided with a valve core hole, and the other end is provided with an air outlet hole. The air inlet hole is located on the side wall of the valve body and is vertically communicated with the air outlet hole and the valve core hole respectively. A ventilation channel is arranged between the air inlet hole and the air outlet hole. The valve core sequentially passes through the valve core hole and the air inlet hole to open or close some ventilation holes on the ventilation channel.

[0005] In the above disclosed prior art, by arranging a conical valve cavity in the valve body, a conical valve core is arranged in the conical valve cavity, a valve core hole is arranged in the middle of the valve core, and a rotating shaft extending out of the valve body is arranged at one end of the valve core. The connection adjustment between the valve core hole and each gas source channel is realized by rotating the valve core, and then the conversion of the gas source is realized. However, in the above scheme, a plurality of different channels are arranged on the valve body to facilitate the flow of different gas sources. Although this method can realize the flow conversion of different gas sources, it is easy to have the situation of incorrect channel connection during the process of converting channels. At the same time, the plurality of arranged channels are not conducive to the processing of the valve body and increase the processing difficulty. In addition, during the use process, a plurality of pipelines need to be connected, and it is also easy to have the situation of incorrect connection for the connection of the pipelines.

Detailed implementation manners

[0027] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0028] As Figures 1-6 shown, an ODS structure with adjustable gas source includes a mounting seat 3 and an adjusting mechanism arranged on the mounting seat 3 for adjusting the gas source flow rate. The adjusting mechanism includes an intake part 1 and an outlet part 2 which are connected. The intake part 1 is provided with an intake port 101 at its end for facilitating the entry of the gas source, and the outlet part 2 is provided with an outlet passage 201 connected to the intake port 101 at its end. An intake passage 102 connected to the intake port 101 is formed inside the intake part 1. An adjusting member 5 for adjusting the intake flow rate is arranged on one side of the intake part 1, and an adjusting hole 501 connected to the intake passage 102 is provided on the adjusting member 5. A ignition member 4 for ignition is arranged on the mounting seat 3.

[0029] Furthermore, the outlet part 2 is fixedly arranged on the mounting seat 3. The intake part 1 is connected to the outlet part 2. The gas source enters from the intake port 101 of the intake part 1, passes through the intake passage 102 and the outlet passage 201 of the outlet part 2, and then flows out from the outlet part 2. Since there is only one intake port 101 and one outlet passage 201, when the adjusting member 5 adjusts the flow rate of the intake passage 102, the situation of incorrect channel connection will not occur. At the same time, both natural gas and liquefied petroleum gas are connected to one intake port 101 and one outlet passage 201, and the situation of incorrect external pipeline connection will not occur either.

[0030] In addition, the adjusting member 5 is arranged along the radial direction of the intake part 1. When the gas source is natural gas, the adjusting hole 501 on the adjusting member 5 is not communicated with the intake passage 102, and the natural gas will enter from the intake port 101 and directly enter the outlet passage 201 from the intake passage 102; when the gas source is liquefied petroleum gas, the adjusting member 5 moves to the deep part of the intake part 1. At this time, the adjusting hole 501 is communicated with the intake passage 102, and the liquefied petroleum gas will enter the intake passage 102 from the intake port 101, and then enter the outlet passage 201 through the adjusting hole 501; at the same time, the inner diameter of the adjusting hole 501 is smaller than the inner diameter of the intake passage 102. By moving the adjusting hole 501 to the inside of the intake part 1 and making the adjusting hole 501 communicate with the intake passage 102, the flow rate of the gas source is changed, and then the flow rate is made more suitable for liquefied petroleum gas, so as to realize the adjustment of the gas source.

[0031] A mounting plate 301 for mounting the entire ODS structure is arranged on the side of the mounting seat 3. The mounting plate 301 is arranged to incline outwards, and mounting holes 302 for connecting bolts are arranged on the mounting plate 301.

[0032] The intake passage 102 includes a first intake passage 1021, a second intake passage 1022 and a third intake passage 1023 which are communicated with each other. The first intake passage 1021 is arranged to incline, the second intake passage 1022 is arranged horizontally, and the third intake passage 1023 is arranged vertically. Further, the top of the first intake passage 1021 is communicated with the intake port 101, the bottom of the first intake passage 1021 is arranged to incline outwards along the radial direction of the intake part 1, the second intake passage 1022 is connected to the bottom end of the first intake passage, and the third intake passage 1023 is connected to the second intake passage 1022. By arranging the first intake passage 1021 to incline, it is convenient to communicate with the second intake passage.

[0033] Specifically, a connection hole 103 communicated with the second intake passage 1022 is arranged in the intake part 1. The connection hole 103 is coaxially arranged with the second intake passage 1022. The adjusting member 5 is arranged in the connection hole 103. Further, the connection hole 103 is arranged along the radial direction of the intake part 1. The connection hole 103 is connected to the end of the second intake passage 1022. The adjusting member 5 is movably arranged in the connection hole 103.

[0034] A transition hole 1031 with a diameter smaller than that of the connection hole 103 is formed in the connection hole 103. A first internal thread 1032 is formed on the inner wall of the transition hole 1031. A first external thread 503 matched with the first internal thread 1032 is formed on the adjusting member 5. Further, the adjusting member 5 is connected in the transition hole 1031. Under the cooperation of the first internal thread 1032 and the first external thread 503, the position of the adjusting member 5 is adjusted, and then the flow rate of the intake passage 102 is adjusted.

[0035] The adjusting hole 501 includes a first adjusting hole 5011 and a second adjusting hole 5012 that are connected and communicate with each other. The first adjusting hole 5011 is arranged along the radial direction of the adjusting member 5, and the second adjusting hole 5012 is arranged along the axial direction of the adjusting member 5. Further, the first adjusting hole 5011 is perpendicularly arranged with respect to the second adjusting hole 5012. The diameter of the first adjusting hole 5011 is the same as that of the second adjusting hole 5012, and both are smaller than the diameter of the air inlet passage 102.

[0036] Specifically, the first adjusting hole 5011 communicates with the third air inlet passage 1023, and the second adjusting hole 5012 communicates with the second air inlet passage 1022. Further, when the gas source is natural gas, the adjusting member 5 is located in the transition hole 1031. At this time, both ends of the first adjusting hole 5011 abut against the inner wall of the transition hole 1031, and the natural gas directly flows through the air inlet passage 102. When the gas source is liquefied petroleum gas, the adjusting member 5 is rotated so that the adjusting member 5 moves into the air inlet part 1, thereby causing the first adjusting hole 5011 to move out of the transition hole 1031. At this time, the adjusting member 5 closes the communication part between the third air inlet passage 1023 and the second air inlet passage 1022, and the first adjusting hole 1031 communicates with the third air inlet passage 1023. After the liquefied petroleum gas enters the second air inlet passage 1022, it enters the second adjusting hole 5012, and then enters the first adjusting hole 5011, and then enters the third air inlet passage 1023 through the first adjusting hole 5011, thereby realizing the adjustment of the flow rate and meeting the requirements of the liquefied petroleum gas for the flow rate.

[0037] A limit ring 502 is provided on the adjusting member 5. When the limit ring 502 abuts against the end of the transition hole 1031, the first adjusting hole 5011 communicates with the third air inlet passage 1023. Further, the limit ring 502 is arranged at the end of the first external thread 503 and is at the end far from the first adjusting hole 5011. When the adjusting member 5 is rotated so that the adjusting member 5 moves into the air inlet part 1, the limit ring 502 abuts against the end of the transition hole 1031. At this time, the first adjusting hole 5011 and the third air inlet passage 1023 are on the same axis, thereby enabling the first adjusting hole 5011 to communicate with the third air inlet passage 1023. Through the cooperation of the provided limit ring 502 and the transition hole 1031, the communication effect between the first adjusting hole 5011 and the third air inlet passage 1023 is ensured, avoiding the situation where the first adjusting hole 5011 cannot accurately communicate with the third air inlet passage 1023, and improving the efficiency and accuracy of adjusting the flow rate of the air inlet passage 102.

[0038] An intake member 105 is provided in the air inlet 101, and a through hole 1051 is formed on the intake member 105. The air source enters the first intake passage 1021 through the through hole 1051 of the intake member 1051. At the same time, an air inlet 202 communicating with the air outlet passage 201 is provided on the air outlet part 2, thereby facilitating the flow of the air source.

[0039] Both ends of the intake part 1 are provided with second external threads 104, and an end of the air outlet passage 201 is formed with a second internal thread 2011 adapted to the second external thread 104. Further, the second external thread 104 is provided on the outer walls at both ends of the intake part 1. The second external thread 104 at the bottom end of the intake part 1 cooperates with the second internal thread 2011 to realize the connection between the intake part 1 and the air outlet part 2, and the second external thread 104 at the top end of the intake part 1 facilitates the connection with the conveying pipeline of the air source.

[0040] An ignition tube 401 is provided on the ignition member 4, and an end of the ignition tube 401 is located directly below the air outlet part 2. Further, an end of the ignition tube 401 is located directly below the air outlet passage 201. The air source flowing out of the air outlet part 2 is ignited by the ignition member 4.
