Description

Technical Field

[0001] This utility model relates to the field of gas stove testing technology, and in particular to an automatic wet gas flow meter for the research and development of gas stoves. Background Technology

[0002] In the production and R&D of gas stoves, accurate gas flow measurement is crucial to ensuring product quality and performance. Precise flow measurement ensures stable and efficient combustion, providing users with a safe and comfortable experience. It also helps companies optimize production processes, improve product qualification rates, and reduce costs. Currently, wet gas flow meters are widely used in gas stove production due to their adaptability to certain humidity environments and high measurement accuracy. However, existing products have several shortcomings in actual use, as follows:

[0003] During installation, the connection between traditional wet gas flow meters and gas stoves is not secure, which can easily lead to gas leaks. This not only wastes energy but also poses safety hazards, such as causing fires or explosions. In addition, some flow meters are complicated to install, which affects the efficiency of installation and commissioning and the progress of production and research and development.

[0004] In terms of leveling, many wet gas flow meters lack effective leveling devices. The levelness of the flow meter directly affects the measurement accuracy. Non-level conditions can easily cause measurement errors and affect the performance and quality of the stove. Traditional manual leveling operations are cumbersome and inefficient, making it difficult to meet the needs of large-scale production.

[0005] Regarding flow data display and transmission, some wet gas flow meters display data that is not intuitive and the transmission is unstable, making it difficult for operators to obtain flow information in a timely and accurate manner, affecting real-time monitoring and adjustment of production. Furthermore, some flow meter plugs are prone to loose connections and are easily loosened by external interference, leading to abnormal data transmission and hindering the normal production of gas stoves. Utility Model Content

[0006] This utility model discloses an automatic wet gas flow meter for the research and development of gas stoves. The operator rotates the adjusting shaft in the leveling mechanism. The adjusting shaft drives the threaded rod to rotate through the meshing bevel gears. Since the threaded rod is connected to the nut by threads, it will rise and fall vertically when rotating, causing the laser sensor installed in the mounting slot above it to move up and down. Continuous rotation of the adjusting shaft enables the lasers of a group of laser sensors to sense each other. A leveling controller is set up, which will receive the signals from the laser sensors in time and make fine adjustments according to the signal feedback until the gas flow meter is in a horizontal state.

[0007] The first aspect of this disclosure provides an automatic wet gas flow meter for the research and development of gas stoves, specifically including: a gas flow meter, an inlet sleeve on one side of the gas flow meter, an outlet sleeve on the other side of the gas flow meter, a reinforcing frame and a locking structure installed on the outer side of the inlet sleeve, a rubber sleeve installed between the inlet sleeve and the reinforcing frame, an impeller and a speed sensor installed inside the gas flow meter, the central shaft of the impeller passing through the inside of the speed sensor, a socket on one side of the gas flow meter, a plug installed at the socket, a numerical display installed on one side of the plug, and a leveling mechanism installed at the bottom of the gas flow meter.

[0008] Furthermore, the gas flow meter has a first stabilizing rod at the middle position at the bottom, an adjusting ball at the bottom of the first stabilizing rod, a nut at the middle position above the support plate, an adjusting hole corresponding to the adjusting ball on the inner side of the nut, and the adjusting ball is installed inside the adjusting hole.

[0009] Furthermore, one side of the rubber sleeve extends into the interior of the air intake sleeve, and the outer side of the rubber sleeve is in close contact with the inner wall of the air intake sleeve. A positioning groove is opened on the outer side of the rubber sleeve. The positioning groove is a circular ring structure, and one side of the reinforcing frame is installed inside the positioning groove.

[0010] Furthermore, the leveling mechanism is composed of a support plate, a second positioning housing, an adjusting shaft, and a threaded rod. The support plate has four symmetrically distributed second positioning housings on its side. A rotating hole is opened at the bottom of the second positioning housing, and the adjusting shaft passes through the interior of the rotating hole.

[0011] Furthermore, a nut is installed at the upper position of the second positioning housing, a through hole communicating with the nut is opened at the upper position of the second positioning housing, and a threaded rod is installed between the second positioning housing and the nut, with the threaded rod and the nut being threadedly connected.

[0012] Furthermore, a set of meshing bevel gears are installed between the adjusting shaft and the threaded rod, and a mounting groove is opened above the threaded rod, with a laser sensor installed inside the mounting groove.

[0013] Furthermore, a first horizontal positioning housing is installed on the outer side of the gas flow meter with a set of screws. A horizontal sliding hole is opened in the middle of the first positioning housing. A second stabilizing rod is installed on the inner side of the sliding hole. A control block and a support spring are provided on the outer side of the second stabilizing rod. The control block passes through the interior of the first positioning housing. A stabilizing groove is opened on one side of the plug to align with the second stabilizing rod. The first positioning housing and the second stabilizing rod cooperate to form a locking structure.

[0014] This utility model provides an automatic wet gas flow meter for the research and development of gas stoves, which has the following beneficial effects:

[0015] A reinforcing bracket with a rubber sleeve is installed on the outside of the gas flow meter. The rubber sleeve makes tight contact with the inner wall of the gas inlet sleeve through elasticity, and the reinforcing bracket is embedded in the positioning groove of the rubber sleeve, which not only facilitates docking with gas stoves, but also effectively prevents gas leakage. At the same time, the cooperation between the stabilizing rod, the support plate nut and the adjustment hole enables flexible angle adjustment and stable installation of the gas flow meter.

[0016] A leveling mechanism is incorporated into the gas flow meter. Rotating the adjusting shaft drives the threaded rod to rise and fall via bevel gear transmission, making the height of the laser sensor adjustable. A group of laser sensors sense each other, and in conjunction with the leveling controller, the gas flow meter can be quickly and accurately adjusted to ensure measurement accuracy.

[0017] The locking structure, consisting of the first positioning housing and the stabilizing rod, automatically engages with the plug stabilizing groove under the action of the support spring. This effectively prevents the plug from becoming loose after installation, prevents external factors from stretching the plug, and extends the plug's service life. The operator can easily unlock and remove the plug by pushing the control block, making the operation simple and convenient.

[0018] The impeller, speed sensor, plug, and numerical display form a complete flow detection loop. Commonly used components are selected. When the impeller rotates, the speed sensor quickly detects the flow and transmits the signal to the numerical display via the USB port. The gas flow is displayed intuitively in an LED structure, which is convenient for real-time monitoring. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0038] Example 1: Please refer to Figures 1 to 8 :

[0039] This utility model proposes an automatic wet gas flow meter for gas stove research and development, comprising: a gas flow meter 1, an inlet sleeve 102 on one side of the gas flow meter 1 (using a mature structure from existing technology), and an outlet sleeve on the other side of the gas flow meter 1. A reinforcing bracket 3 and a locking structure 5 are installed on the outer side of the inlet sleeve 102. A horizontal first positioning housing 501 is installed on the outer side of the gas flow meter 1 with a set of screws. A horizontal sliding hole is opened in the middle of the first positioning housing 501. A second stabilizing rod 502 is installed on the inner side of the sliding hole. A control block and a support spring are installed on the outer side of the second stabilizing rod 502. The control block passes through... Inside the first positioning housing 501, a stabilizing groove is opened on one side of the plug 4, which is aligned with the second stabilizing rod 502. The support spring can push the second stabilizing rod 502 to return to its original position and automatically extend into the stabilizing groove. The first positioning housing 501 and the second stabilizing rod 502 cooperate to stabilize the installation position of the plug 4, preventing the plug 4 from becoming loose after installation and preventing the plug 4 from being stretched under any external factors. This allows the gas flow meter 1 to operate stably and extends the service life of the plug 4. The operator can push the control block with their finger to move the second stabilizing rod 502 in the opposite direction. At this time, the plug 4 can be unlocked and removed. The first positioning housing 501 and the second stabilizing rod 502 cooperate to form a locking structure 5.

[0040] In this embodiment of the disclosure, reference is made to Figures 1 to 8As shown, a rubber sleeve 2 is installed between the intake sleeve 102 and the reinforcing frame 3. Referring to the riveting structure of existing technology, the intake sleeve 102 and the reinforcing frame 3 are stably assembled. One side of the rubber sleeve 2 extends into the interior of the intake sleeve 102. Due to the elastic rubber material of the rubber sleeve 2, the outer surface of the rubber sleeve 2 is in close contact with the inner wall of the intake sleeve 102. A positioning groove is formed on the outer surface of the rubber sleeve 2. The positioning groove is a circular structure. One side of the reinforcing frame 3 is installed inside the positioning groove. The reinforcing frame 3 is made of metal material as needed, according to existing technology. The reinforcing frame 3 further reinforces the rubber sleeve 2. The rubber sleeve 2 is used to connect to the gas stove connector and prevent gas leakage during flow. An impeller and a speed sensor are installed inside the gas flow meter 1. The central shaft of the impeller passes through the inside of the speed sensor. The impeller and speed sensor are selected from commonly used models in the gas flow meter 1. A port is located on one side of the gas flow meter 1. The port uses a USB structure and is electrically connected to the speed sensor according to existing technology. A plug 4 is installed at the port. A numerical display is installed on one side of the plug 4. The numerical display uses an LED structure commonly used for flow display in existing technology and is electrically connected to the plug 4 according to existing technology, forming a complete flow detection circuit with the impeller, speed sensor, plug 4, and numerical display. A leveling mechanism 6 is installed at the bottom of the gas flow meter 1. The leveling mechanism 6 consists of a support plate 601, a second positioning housing 602, an adjusting shaft 603, and a threaded rod 604. Four symmetrically distributed second positioning housings 602 are located on the side of the support plate 601. The bottom of each second positioning housing 602 has an opening... A rotating hole is provided, through which the adjusting shaft 603 passes. The rotating position of the adjusting shaft 603 is laterally positioned by means of a rotation positioning structure in the prior art, so that the adjusting shaft 603 can rotate stably in the position of the rotating hole. A nut is installed on the upper position of the second positioning housing 602. A through hole communicating with the nut is opened on the upper position of the second positioning housing 602. The second positioning housing 602 and the nut need to be stably assembled by welding in the prior art. A threaded rod 604 is installed between the second positioning housing 602 and the nut, and the threaded rod 604 is threadedly connected to the nut.

[0041] In this embodiment of the disclosure, reference is made to Figures 1 to 8As shown, a first stabilizing rod 101 is provided at the middle position of the bottom of the gas flow meter 1. An adjusting ball is provided at the bottom of the first stabilizing rod 101. A nut is installed at the middle position of the upper part of the support plate 601. An internal thread is provided at the bottom position of the inner side of the nut using existing technology, so that the nut is securely installed at the upper position of the support plate 601 with the internal thread. An adjusting hole corresponding to the adjusting ball is opened at the inner side of the nut. The adjusting ball is installed in the inner position of the adjusting hole. The setting of the nut facilitates the assembly of the gas flow meter 1 and the support plate 601. The first stabilizing rod 101, adjusting ball, and adjusting hole cooperate with each other to achieve the effect of flexible adjustment of the angle of the gas flow meter 1.

[0042] In this embodiment of the disclosure, reference is made to Figures 1 to 8 As shown, a set of meshing bevel gears is installed between the adjusting shaft 603 and the threaded rod 604. The bevel gears serve as a reversing transmission. When the operator rotates the adjusting shaft 603, it drives the bevel gears to rotate. When the bevel gears rotate, they drive the threaded rod 604 to rotate. With the cooperation of the nut, the threaded rod 604 can be raised and lowered vertically. A mounting groove is opened at the top of the threaded rod 604. A laser sensor is installed inside the mounting groove. The mounting groove hides and positions the installation position of the laser sensor. The specific model of the laser sensor is selected according to the size of the mounting groove. The height of the laser sensor is adjusted by the threaded rod 604, so that the lasers of the set of laser sensors can sense each other. At this time, under the action of the laser sensors, the gas flow meter 1 can achieve a rapid leveling effect.

[0043] Example 2, based on Example 1, with reference to Figures 1 to 8 As shown, a leveling controller based on existing technology needs to be set up, and the leveling controller and a set of laser sensors are electrically connected respectively, so that the leveling controller can receive the signals from the laser sensors in a timely manner.

[0044] The working principle of this embodiment:

[0045] Connect the air intake sleeve 102 to the rubber sleeve 2. Refer to the existing riveting structure to stably assemble the air intake sleeve 102 and the reinforcing frame 3. The positioning groove on the outside of the rubber sleeve 2 cooperates with the reinforcing frame 3 to further stabilize the connection.

[0046] According to the actual installation requirements, the adjusting ball on the first stabilizing rod 101 at the bottom of the gas flow meter 1 is placed into the adjusting hole of the nut above the support plate 601 for positioning.

[0047] The leveling operation steps for gas flow meter 1 are as follows: The operator rotates the adjusting shaft 603 in the leveling mechanism 6. The adjusting shaft 603 drives the threaded rod 604 to rotate through the meshing bevel gears. Since the threaded rod 604 is threadedly connected to the nut, it will rise and fall vertically when rotating, causing the laser sensor installed in the mounting slot above it to move up and down. By continuously rotating the adjusting shaft 603, the lasers of a group of laser sensors can sense each other. The leveling controller is set up, which will receive the signal from the laser sensor in time and make fine adjustments according to the signal feedback until the gas flow meter 1 is in a horizontal state.

[0048] In the flow detection connection steps, the operator inserts plug 4 into the USB port on one side of the gas flow meter 1. At this time, the support spring pushes the second stabilizing rod 502 to automatically extend into the stabilizing groove on one side of plug 4, so that plug 4 is installed securely to prevent loosening. Then, the rubber sleeve 2 is put on the connector of the gas stove. Because the rubber sleeve 2 is elastic, it can fit tightly to prevent gas leakage.

[0049] When the gas stove is turned on, the gas enters the gas flow meter 1 through the gas inlet sleeve 102, which drives the internal impeller to rotate. The rotation of the impeller drives the central shaft to rotate. The speed sensor detects the speed of the central shaft and transmits the signal to the numerical display through the plug 4. The gas flow value is displayed in real time on the numerical display.
