[0001] This utility model relates to the field of burner technology, and in particular to a stove burner. Background Technology

[0002] Existing stove burners include a gas distribution base and a burner cap. The burner cap and the gas distribution base are separate structures. During use, when the burner cap's flame holes become clogged or dirty, the user can remove the burner cap for cleaning. However, when putting it back in its original position, it is not easy to align the burner cap properly, resulting in a gap between the burner cap and the gas distribution base due to improper installation, which can lead to flame leakage and other problems. Utility Model Content

[0003] The purpose of this utility model is to propose a stove burner that solves the technical problem in the prior art where improper installation of the burner cap results in a gap between it and the gas distribution seat, leading to flame leakage.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] This utility model provides a stove burner, including a gas distribution seat and an outer ring flame cap. The gas distribution seat is provided with an outer ring mixing chamber, and the outer ring flame cap is disposed above the outer ring mixing chamber.

[0006] A matching sensing device is provided on the top end face of the side wall of the outer ring mixing chamber and one of the outer ring flame caps, and the top end face of the side wall of the outer ring mixing chamber and the other of the outer ring flame caps are positioned and matched with the matching sensing device.

[0007] A positioning sensor is provided in one of the outer ring mixing chambers and the outer ring flame cap, and a positioning post is provided in the other of the outer ring mixing chambers and the outer ring flame cap. The positioning post is positioned in conjunction with the positioning sensor.

[0008] This stove burner features a matching sensing device installed on the top end face of the side wall of the outer ring mixing chamber and on one of the outer ring burner caps. The top end face of the side wall of the outer ring mixing chamber and the other outer ring burner cap are positioned and matched with the matching sensing device. A positioning sensing device is installed inside the outer ring mixing chamber and on one of the outer ring burner caps. A positioning post is installed inside the outer ring mixing chamber and on the other outer ring burner cap. The positioning post is positioned and matched with the positioning sensing device. The matching sensing device and the positioning sensing device can detect whether the outer ring burner cap is installed correctly, thus avoiding flame leakage problems caused by improper installation of the outer ring burner cap.

[0009] As a preferred embodiment of the above-mentioned stove burner, the top end face of the outer or inner side wall of the outer ring mixing chamber is the gas distribution seat mating surface, the lower end face of the outer ring burner cap is the burner cap mating surface, and the mating sensing device is provided on the gas distribution seat mating surface, and the mating sensing device is positioned and mated with the burner cap mating surface.

[0010] The matching sensing device is placed on the matching sensing surface of the gas distributor seat, and the matching sensing device and the matching surface of the burner cap are matched. The above setting makes the installation of the outer ring burner cap more convenient and avoids the inconvenience caused by the setting of the matching sensing device.

[0011] As a preferred embodiment of the aforementioned stove burner, multiple induction devices are provided.

[0012] Multiple sensors are set up to detect the coverage of the outer ring flame cover, thereby improving detection accuracy and avoiding incorrect judgments caused by the failure of a single sensor due to manufacturing errors.

[0013] As a preferred embodiment of the above-mentioned stove burner, a plurality of the aforementioned mating sensing devices are arranged at equal intervals along the circumference of the mating surface of the gas distribution seat.

[0014] The above settings can effectively detect the proper installation of the outer ring fire cover, and the detection is relatively accurate.

[0015] As a preferred embodiment of the above-mentioned stove burner, a positioning hole is provided at the bottom inner side of the outer ring mixing chamber, and the positioning sensing device is disposed in the positioning hole.

[0016] The positioning hole facilitates the installation of the positioning sensor.

[0017] As a preferred embodiment of the above-mentioned stove burner, multiple positioning holes are provided, and the multiple positioning holes are arranged at equal intervals along the circumference of the gas distribution seat. Each positioning hole is provided with a positioning sensing device.

[0018] Multiple positioning holes are provided, and each positioning hole is equipped with a positioning sensor. The multiple positioning sensors can improve the inspection of the outer ring fire cover's installation status and increase the accuracy of the detection.

[0019] As a preferred embodiment of the above-mentioned stove burner, the contact surface between the mating sensing device and the mating surface of the burner cap is the first surface, and the contact surface between the positioning sensing device and the positioning post is the second surface. The plane containing the first surface and the plane containing the second surface are intersecting.

[0020] The plane containing the first surface and the plane containing the second surface are intersecting to ensure that when the outer ring fire cover is correctly installed, the first surface and the second surface can be fitted in place simultaneously. This prevents situations where one surface fits in place while the other surface has a gap due to processing errors or other reasons, thus avoiding misjudgment.

[0021] As a preferred embodiment of the aforementioned stove burner, the first surface is arranged horizontally.

[0022] The first side is arranged horizontally, which makes it easier to place the sensing device.

[0023] As a preferred embodiment of the above-mentioned stove burner, the positioning sensing device has a ring structure, the inner diameter of the positioning sensing device gradually decreases from top to bottom, the positioning post extends into the positioning sensing device and can abut against the inner sidewall of the positioning sensing device.

[0024] The positioning sensor has a ring structure, and the inner diameter of the positioning sensor gradually decreases from top to bottom, so that when the positioning pin extends into the positioning sensor, it can abut against the inner wall of the positioning sensor, thus facilitating the detection of the outer ring fire cover's installation status.

[0025] As a preferred embodiment of the above-mentioned stove burner, the stove burner further includes a prompting device, and the matching sensing device and the positioning sensing device are electrically connected to the prompting device.

[0026] The prompting device can provide alerts on the detection status of the cooperating sensing device and the positioning sensing device, and can promptly remind you when the outer ring flame cap is not installed properly, thus avoiding flame leakage problems caused by improper installation of the outer ring flame cap.

[0027] The beneficial effects of this utility model are:

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0044] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0047] Existing stove burners consist of a gas distributor and a burner cap, which are separate components. During use, when the burner cap's flame holes become clogged or dirty, users can remove the burner cap for cleaning. However, when putting it back in its original position, it's not easy to align the burner cap perfectly, resulting in a gap between the burner cap and the gas distributor due to improper installation, leading to flame leakage. It should be noted that the burner cap consists of an outer ring burner cap and an inner ring burner cap; flame leakage is mainly caused by improper installation of the outer ring burner cap.

[0048] To solve the above problems, such as Figures 1-6As shown, this embodiment provides a stove burner, including a gas distribution base 1, an outer ring burner cap 2, and an inner ring burner cap 3. The gas distribution base 1 has an inner ring mixing chamber and an outer ring mixing chamber 11. The inner ring mixing chamber is connected to the outer ring mixing chamber 11 through several gas distribution channels. The outer ring burner cap 2 is placed above the outer ring mixing chamber 11. A matching sensing device 4 is provided on the top end face of the side wall of the outer ring mixing chamber 11 and on one of the outer ring burner caps 2. The top end face of the side wall of the outer ring mixing chamber 11 and the other outer ring burner cap 2 are positioned and matched with the matching sensing device 4. A positioning sensing device 5 is provided inside the outer ring mixing chamber 11 and on one of the outer ring burner caps 2. A positioning post 22 is provided inside the outer ring mixing chamber 11 and on the other outer ring burner cap 2. The positioning post 22 is positioned and matched with the positioning sensing device 5. The matching sensing device 4 and the positioning sensing device 5 can detect whether the outer ring burner cap 2 is installed in place, avoiding the problem of flame leakage caused by improper installation of the outer ring burner cap 2.

[0049] Optionally, the top end face of the outer or inner side wall of the outer ring mixing chamber 11 is the gas distributor mating surface 12, and a mating sensing device 4 is provided on the gas distributor mating surface 12, such as... Figure 3 As shown, a matching sensing device 4 is provided on the top end face of the outer wall of the outer ring mixing chamber 11. For example... Figure 4 As shown, the lower end face of the outer ring burner cap 2 is the burner cap mating surface 21, and the mating sensing device 4 is positioned and mated with the burner cap mating surface 21. The mating sensing device 4 is placed on the mating sensing surface of the gas distributor 1, and the mating sensing device 4 is inductively mated with the burner cap mating surface 21. This arrangement makes the installation of the outer ring burner cap 2 more convenient and avoids installation inconvenience caused by the placement of the mating sensing device 4. Figure 3 As shown, a positioning sensing device 5 is installed inside the outer ring mixing chamber 11, such as... Figure 4 As shown, a positioning post 22 is provided on the outer ring fire cover 2.

[0050] Optionally, multiple matching sensing devices 4 and multiple positioning sensing devices 5 are provided. By using multiple matching sensing devices 4 and multiple positioning sensing devices 5 to detect the installation status of the outer ring flame cap 2, the detection accuracy is improved, and errors in judgment caused by the failure of a single matching sensing device 4 or positioning sensing device 5 due to processing errors are avoided. Preferably, the multiple matching sensing devices 4 are arranged at equal intervals along the circumference of the gas distributor mating surface 12. The above arrangement can achieve a better detection effect on the installation status of the outer ring flame cap 2, and the detection is more accurate. In this embodiment, four matching sensing devices 4 are arranged at equal intervals along the circumference of the gas distributor mating surface 12. The number of matching sensing devices 4 is not limited to four; it can also be two, three, five, or more. Three outer ring mixing chambers 11 are provided, and one positioning sensing device 5 is provided in each outer ring mixing chamber 11. The three positioning sensing devices 5 are arranged at equal intervals along the circumference of the gas distributor 1. The number of positioning sensing devices 5 is not limited to three; it can also be two, four, five, or more.

[0051] Furthermore, such as Figure 3 As shown, a positioning hole 13 is provided at the bottom inner side of the outer ring mixing chamber 11, and the positioning sensing device 5 is disposed in the positioning hole 13. The positioning hole 13 facilitates the installation of the positioning sensing device 5.

[0052] Preferably, multiple positioning holes 13 are provided, and the multiple positioning holes 13 are arranged at equal intervals along the circumference of the gas distribution seat 1. In this embodiment, three positioning holes 13 are provided, one positioning hole 13 is provided in each outer ring mixing chamber 11, and a positioning sensing device 5 is provided in each positioning hole 13. The provision of multiple positioning sensing devices 5 can improve the inspection of the covering status of the outer ring flame cover 2 and improve the detection accuracy.

[0053] Optionally, the contact surface between the sensing device 4 and the flame cap mating surface 21 is the first surface, and the contact surface between the positioning sensing device 5 and the positioning post 22 is the second surface. The plane containing the first surface and the plane containing the second surface are intersecting, that is, the first surface and the second surface are not parallel. This arrangement ensures that when the outer ring flame cap 2 is correctly installed, the first surface and the second surface can be mated in place at the same time, preventing one surface from being mated in place while the other surface has a gap due to processing errors or other reasons, thereby avoiding misjudgment.

[0054] In this embodiment, as Figure 6 As shown, the first side is arranged horizontally, which makes the placement of the sensing device 4 relatively simple. The positioning sensing device 5 has a ring structure, and the inner diameter of the positioning sensing device 5 gradually decreases from top to bottom. The positioning post 22 extends into the positioning sensing device 5 and can abut against the inner side wall of the positioning sensing device 5, thereby facilitating the detection of the covering status of the outer ring fire cover 2.

[0055] It should be noted that the sensing device 4 and the positioning sensing device 5 are not limited to pressure sensors, piezoelectric sensors, etc. The specific detection principles of pressure sensors and piezoelectric sensors are existing technologies and will not be elaborated here.

[0056] Optionally, the stove burner also includes a warning device (not shown in the figure), which is electrically connected to the sensing device 4 and the positioning sensing device 5. The warning device indicates the detection status of the sensing device 4 and the positioning sensing device 5, and can promptly remind the user if the outer ring burner cap 2 is not installed correctly, thus preventing flame leakage caused by improper installation. It should be noted that the warning device can be a voice warning device or a light warning device, or both can be installed simultaneously. The warning device is a conventional structure and will not be described in detail here.

[0057] In one optional embodiment, the number of mating sensors 4 is X, and the number of positioning sensors 5 is Y. When the number of signals from the mating sensors 4, M ≥ 0.5X, it is determined that the mating sensors 4 have a signal; when the number of signals from the positioning sensors 5, N ≥ 0.5Y, it is determined that the positioning sensors 5 have a signal. This method of processing the sensor signals avoids detection errors caused by manufacturing mistakes. When the number of signals from both the mating sensors 4 and the positioning sensors 5 is greater than or equal to 0.5 times their respective numbers, the mating is considered complete, and a completion indication signal is issued.

[0058] like Figure 7 As shown, if there is no signal from both the sensing device 4 and the positioning sensing device 5, it indicates that the outer ring flame cap 2 is not placed on the gas distribution seat 1, and a prompt "Flame cap not placed" is issued, and the electrode needle is prohibited from discharging and igniting to ensure gas safety.

[0059] like Figure 8 As shown, when the sensing device 4 has a signal but the positioning sensing device 5 has no signal, it indicates that the outer ring burner cap 2 is placed on the gas distribution seat 1 but not in the correct position, and a prompt "burner cap not in the correct position" is issued, and the electrode needle is prohibited from discharging and igniting. In this case, there is a gap between the outer ring burner cap 2 and the gas distribution seat 1, which may lead to flame leakage. At this time, the electrode needle is prohibited from discharging and igniting to ensure the safety of using the stove.

[0060] like Figure 9 As shown, when both the sensing device 4 and the positioning sensing device 5 have a signal, it indicates that the outer ring burner cap 2 is placed on the gas distribution seat 1 and is in place, and a prompt "burner is ready" is issued, allowing the electrode needle to discharge and ignite.

[0061] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
