Multi-head gas device capable of preventing blockage

Abstract

This utility model discloses a multi-head anti-clogging gas device, relating to the technical field of gas device technology. It includes a delivery pipeline with a cover plate fixedly connected to its side wall, and a drive motor fixedly connected to the outer wall of the cover plate. This utility model, through its delivery pipeline, cover plate, drive motor, and blade rod, uses the drive motor to rotate the blade rod, creating a disturbance and pushing effect on the gas inside the pipe. This makes the gas flow more uniform and stable, preventing local impurity deposition due to airflow stagnation, improving subsequent combustion efficiency, reducing local pressure loss, ensuring a more balanced gas supply to each branch pipeline, and preventing abnormal flames due to insufficient gas supply to a particular pipeline. It solves the problem that in traditional gas pipelines, impurities in the gas easily accumulate on the inner wall of the pipe and at branch interfaces due to airflow stagnation during long-term use, leading to a smaller pipe diameter, increased resistance, and even blockage.

Description

Technical Field

[0001] This utility model relates to the field of gas device technology, specifically a multi-head anti-clogging gas device. Background Technology

[0002] With the acceleration of urbanization and the improvement of residents' living standards, natural gas, as a clean and efficient energy source, has been widely used in many fields such as home cooking, commercial catering, and industrial heating. In order to meet the simultaneous gas demand in multiple scenarios, multi-burner gas devices have seen a year-on-year increase in market demand due to their high efficiency and convenience. However, in the long-term use of traditional multi-burner gas devices, due to the limitations of structural design and technology, a series of problems affecting performance and safety have gradually been exposed. Therefore, a multi-burner anti-clogging gas device is needed.

[0003] Existing multi-head anti-clogging gas devices suffer from uneven and unstable gas flow during operation, leading to localized impurity deposition and blockage due to airflow stagnation. To prevent blockage, some devices use filters at the pipe inlet to intercept impurities, but these filters are mostly fixed structures, requiring tools for disassembly and cleaning, and can only intercept large particles, failing to address the deposition problem caused by airflow stagnation inside the pipe. Regarding burner protection, some products lack protective measures, resulting in burners rusting and corroding due to moisture or deformation and damage from external impacts. Therefore, a multi-head anti-clogging gas device is urgently needed. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a multi-head anti-clogging gas device to solve the problem that existing multi-head anti-clogging gas devices do not have uniform and stable gas flow during use, which leads to local impurity deposition and blockage due to airflow stagnation. In terms of anti-clogging, some devices use filters installed at the pipe inlet to intercept impurities, but the filters are mostly fixed structures, requiring tools for disassembly and cleaning, and can only intercept large particles of impurities, failing to solve the problem of deposition caused by airflow stagnation inside the pipe. In terms of burner protection, some products lack protective measures, resulting in burners rusting and corroding due to moisture, or deformation and damage caused by collisions with external objects.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-head anti-clogging gas device, including a conveying pipe, a cover plate fixedly connected to the side wall of the conveying pipe, a drive motor fixedly connected to the outer wall of the cover plate, and a blade rod fixedly connected to the drive motor through a coupling.

[0006] The side wall of the conveying pipe is provided with a base, and the side wall of the conveying pipe is provided with a magnetic mounting bracket. The outer wall of the magnetic mounting bracket has a slot, and the outer wall of the magnetic mounting bracket is provided with a magnetic sealing cover. The inner wall of the magnetic sealing cover has a snap-fit ​​compartment, and the inner wall of the snap-fit ​​compartment is fixedly connected with a return spring. One end of the return spring is provided with a fixing snap. The inner wall of the conveying pipe is provided with a filter screen.

[0007] The base is provided with a work station ring on the top, a burner is provided on the inner wall of the work station ring, and a protective cover is installed on the outer wall of the burner.

[0008] Preferably, the outer wall of the cover plate is perforated, and the cover plate is engaged with the output shaft of the drive motor.

[0009] Preferably, the blade rod is movably connected to the conveying pipe, and the blade rod forms a rotating structure with the conveying pipe through a drive motor.

[0010] Preferably, the fixing buckle is telescopically connected to the magnetic mounting frame via a reset spring, and the fixing buckle is inserted into the slot.

[0011] Preferably, the magnetic sealing cover is magnetically fixed to the magnetic mounting bracket, and the magnetic sealing cover is engaged with the magnetic mounting bracket by a fixing buckle.

[0012] Preferably, the inner wall of the protective cover is threaded, and the protective cover is threadedly connected to the work station ring.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the setting of a delivery pipe, cover plate, drive motor and blade rod, drives the blade rod to rotate by starting the drive motor, which creates a certain disturbance and pushing effect on the gas in the pipe, making the gas flow more uniform and stable, avoiding the local impurity deposition caused by airflow stagnation. At the same time, this disturbance can also assist the premixing of gas and air, improve the subsequent combustion efficiency, reduce local pressure loss, ensure a more balanced gas supply to each branch pipe, and avoid abnormal flame due to insufficient gas supply to a certain pipe. It solves the problem that in traditional gas pipelines, impurities in the gas are easily deposited on the inner wall of the pipe and at the branch interface due to airflow stagnation during long-term use, which leads to a smaller inner diameter of the pipe, increased resistance, and even blockage. 2. This utility model, through its conveying pipe, magnetic mounting bracket, slot, magnetic sealing cover, buckle compartment, return spring, fixing buckle, and filter screen, allows for easy installation. The filter screen is inserted into the groove within the conveying pipe, and the magnetic sealing cover is secured with the fixing buckle. The filter screen can then be removed by reversing the process, requiring no tools. This convenient maintenance method encourages users to regularly clean or replace the filter screen, preventing gas flow reduction due to filter clogging. It also reduces the cost of on-site service by professional maintenance personnel. Furthermore, the filter screen intercepts rust, impurities, and moisture within the conveying pipe, preventing blockages. Combined with the existing blade rod's anti-clogging function, this forms a "double protection," further reducing the probability of pipe blockage. 3. This utility model, through its base, work station ring, burner, and protective cover, allows the burner to be completely covered when not in use by placing the protective cover over the work station ring, forming a physical protective barrier. This effectively prevents foreign objects such as dust, oil, and insects from entering the burner, avoiding blockage of the flame holes that could lead to unstable or non-combustion. At the same time, the sealed fit between the protective cover and the work station ring prevents moisture from entering the burner, preventing it from rusting and corroding due to dampness. Furthermore, the transparent protective cover also prevents external objects from colliding with the burner, avoiding deformation and damage. Attached Figure Description

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0017] The embodiments of this utility model will be described below based on its overall structure.

[0018] Please see Figure 1 - Figure 5 A multi-head anti-clogging gas device includes a delivery pipe 1, a cover plate 2 fixedly connected to the side wall of the delivery pipe 1, a drive motor 3 fixedly connected to the outer wall of the cover plate 2, and a blade rod 4 fixedly connected to the drive motor 3 via a coupling. The outer wall of the cover plate 2 is perforated, and the cover plate 2 is engaged with the output shaft of the drive motor 3. The blade rod 4 is movably connected to the delivery pipe 1, and the blade rod 4 forms a rotating structure with the delivery pipe 1 via the drive motor 3. When using the device, by starting the drive motor 3, the output shaft of the drive motor 3 drives the blade rod 4 to rotate. Driven by the rotation of the blade rod 4, an axial pushing force is generated, which pushes the gas to flow stably along the direction of the delivery pipe 1. This not only makes the gas flow velocity distribution more uniform, but also avoids the situation where the gas supply to other branches is insufficient due to the instantaneous increase in gas consumption in one branch.

[0019] Please see Figure 1 - Figure 5 A multi-head anti-clogging gas device includes a base 5 on the side wall of a delivery pipe 1, a magnetic mounting bracket 6 on the side wall of the delivery pipe 1, a slot 7 on the outer wall of the magnetic mounting bracket 6, a magnetic sealing cover 8 on the outer wall of the magnetic mounting bracket 6, a latching chamber 9 on the inner wall of the magnetic sealing cover 8, a return spring 10 fixedly connected to the inner wall of the latching chamber 9, a fixing latch 11 at one end of the return spring 10, a filter screen 12 installed on the inner wall of the delivery pipe 1, and the fixing latch 11 forms a telescopic structure with the magnetic mounting bracket 6 through the return spring 10, and the fixing latch 11 is inserted into the slot 7. The magnetic sealing cover 8 is magnetically fixed to the magnetic mounting bracket 6, and the magnetic sealing cover 8 is engaged with the magnetic mounting bracket 6 through the fixing latch 11. When using the device, the filter screen 12 is inserted into the groove provided in the delivery pipe 1, and then pressed to secure it. When the fixed buckle 11 is pressed, it slides inward along the guide protrusion of the buckle compartment 9, simultaneously driving the return spring 10 to compress to the bottom of the buckle compartment 9. Then, the magnetic sealing cover 8 is inserted into the magnetic mounting bracket 6 for initial fixation using magnetism, aligning the fixed buckle 11 with the slot 7. Then, the fixed buckle 11 is released, and the return spring 10 pushes the fixed buckle 11 into the slot 7 for fixation, thus completing the installation of the filter screen 12. The filter screen 12 can then be removed by reversing the operation. The filter screen 12 can intercept rust, impurities, and moisture in the delivery pipeline 1, preventing blockage caused by rust, impurities, and moisture. The filter screen 12 can be quickly replaced without the need for tools, avoiding the problem of reduced gas flow due to filter screen 12 blockage, and reducing the on-site service cost for professional maintenance personnel.

[0020] Please see Figure 1 - Figure 5 A multi-head anti-clogging gas device has a base 5 with a station ring 13 on top. A burner 14 is installed on the inner wall of the station ring 13, and a protective cover 15 is installed on the outer wall of the burner 14. When using the device, align the open end of the protective cover 15 with the top of the station ring 13, so that the internal thread of the protective cover 15 is aligned with the external thread of the station ring 13. Take care to avoid misalignment of the threads, which may prevent installation or damage to the threads. Rotate the protective cover 15, and keep the force even during the rotation to avoid excessive force that may cause the threads to strip. As the protective cover 15 is rotated, it gradually moves downward and is fixed on the station ring 13. This can effectively protect the burner 14 when it is not in use.

[0021] Working principle: In use, first move the device to a suitable position, then insert the filter screen 12 into the groove inside the conveying pipe 1. Next, press the fixing buckle 11; the fixing buckle 11 is pressed and retracts into the buckle chamber 9, simultaneously compressing the return spring 10. Then, insert the magnetic sealing cover 8 into the magnetic mounting bracket 6 for initial fixation using magnetism. Then, release the fixing buckle 11; the return spring 10 pushes the fixing buckle 11 into the slot 7 for fixation, thus completing the installation of the filter screen 12. In use, the filter screen 12 can intercept rust, impurities, and moisture inside the conveying pipe 1. Then, by reversing the operation, the filter screen 12 can be removed without the need for tools. The drive motor 3 can be started, and the output shaft of the drive motor 3 will drive the blade rod 4 to rotate. Driven by the rotation of the blade rod 4, it will create a certain disturbance and pushing effect on the gas in the pipe. When the burner 14 is not in use, simply cover the protective cover 15 on the station ring 13, and then rotate the protective cover 15 to fix the protective cover 15 on the station ring 13 with threads, so as to effectively protect the burner 14. This completes the use of the device. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
