[0036] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0037] In the description of this application, it should be understood that the terms "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on this application.

[0038] The terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the quantity of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features.

[0039] In the description of this application, it should be noted that, unless otherwise specified or limited, the term "connection" should be understood in a broad sense. For example, it can mean a fixed connection, a detachable connection, or an integral connection; it can mean a direct connection, an indirect connection through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0040] like Figures 1-4 As shown, this embodiment provides a gas stove ignition distributor, comprising a base 1, two outer ring ejection tubes 2, and an inner ring ejection tube 4. The base 1 is provided with an outer ring sidewall, a middle ring sidewall, and an inner ring sidewall. An outer ring groove 11 is formed between the outer ring sidewall and the middle ring sidewall, and the inner ring sidewalls enclose a central air outlet 12. The two outer ring ejection tubes 2 are disposed at the bottom of the base 1, and the inner ring ejection tube 4 is disposed at the bottom of the central air outlet 12. The air outlets of the two outer ring ejection tubes 2 are connected to the outer ring groove 11 through two symmetrically arranged connecting ports 113, respectively, so that the gas is ejected through the connecting ports 113 into the outer ring groove 11 to mix with the air; the air outlet of the inner ring ejection tube 4 is connected to the central air outlet 12, so that the gas is ejected into the central air outlet 12 of the base 1 to mix with the air.

[0041] In the prior art gas stove ignition distributor, the two air flows emitted from the outlets of the two outer ring ejector tubes 2 to the outer ring groove 11 collide with each other, causing a sudden increase in the gas pressure in the outer ring groove 11, resulting in flickering combustion flames in the outer ring of the gas stove and unstable combustion.

[0042] In order to solve the above problems, the gas stove ignition distributor provided in this embodiment is further provided with a flow guide assembly 3 on the base body 1. The flow guide assembly 3 includes a partition plate 31, which is vertically arranged in the outer ring groove 11 and located between the two connecting ports 113. The two ends of the partition plate 31 are respectively connected to the two side walls of the outer ring groove 11. The partition plate 31 separates the two convective airflows. After the two airflows enter the outer ring groove 11, they flow along the opposite side walls of the partition plate 31 respectively to prevent the two airflows from colliding with each other. The projection of the partition plate 31 on the bottom of the outer ring groove 11 is set to intersect with the symmetry line of the two connecting ports 113 to reduce the pressure generated by the collision between the two airflows and the partition plate 31, reduce the gas pressure change in the outer ring groove 11, avoid the sudden increase in the pressure of the two airflows in the outer ring groove 11, and make the combustion flame more uniform and stable.

[0043] In one embodiment, the angle between the partition plate 31 and the sidewall of the outer annular groove 11 is a predetermined angle, preferably between 20° and 25°. By limiting the predetermined angle range, the inclination of the partition plate 31 within the outer annular groove 11 is restricted, thereby maximizing the flow paths of the two airflows within the outer annular groove 11 and mitigating changes in gas pressure within the outer annular groove 11.

[0044] Furthermore, if Figure 3 and Figure 5 As shown, the partition plate 31 is an arc-shaped plate, and the side of the arc-shaped plate colliding with the two airflows is an arc-shaped surface, which reduces the collision pressure of the airflow and further reduces the change of the gas pressure in the outer ring groove 11.

[0045] Specifically, continue to refer to Figure 3 The tangent line of the outer side wall of the outer ring groove 11 passing through the connection between one end of the curved plate and the outer side wall of the outer ring groove 11 is a first tangent line 100, and the tangent line of one end of the curved plate passing through the connection between one end of the curved plate and the outer side wall of the outer ring groove 11 is a second tangent line 200. The angle between the first tangent line 100 and the second tangent line 200 is a preset angle. Similarly, the tangent line of the inner side wall of the outer ring groove 11 passing through the connection between the other end of the curved plate and the inner side wall of the outer ring groove 11 is a third tangent line 300, and the tangent line of the other end of the curved plate passing through the connection between the other end of the curved plate and the inner side wall of the outer ring groove 11 is a fourth tangent line 400. The angle between the third tangent line 300 and the fourth tangent line 400 is also a preset angle. For example, the preset angle is α, and α=23°.

[0046] Of course, in other embodiments, the partition plate 31 may also be a flat plate, which is tilted and disposed in the outer annular groove 11 .

[0047] In one embodiment, the flow guide assembly 3 further includes a flow guide plate 32, which is disposed at the end of the partition plate 31 away from the bottom of the outer annular groove 11. The two sides of the flow guide plate 32 are respectively in contact with the two side walls of the outer annular groove 11. By providing the flow guide plate 32, the outer annular groove 11 is divided into two channels by the two side walls, the bottom, the partition plate 31, and the flow guide plate 32. The two airflows enter the channel adjacent to the corresponding communication opening 113 from their respective channels, and then collide with one side of the partition plate 31, changing their direction.

[0048] In one embodiment, two connecting ports 113 separate the outer annular groove 11 into a first arcuate groove 111 and a second arcuate groove 112. The central angle of the first arcuate groove 111 is smaller than the central angle of the second arcuate groove 112. The flow guide assembly 3 is disposed within the first arcuate groove 111. Because the central angle of the first arcuate groove 111 is less than 180°, the gas ejected from the gas outlets of the two outer annular ejector tubes 2 enters the outer annular groove 11 through the two symmetrical connecting ports 113 and quickly collides within the first arcuate groove 111. This increases the gas pressure and concentration within the first arcuate groove 111, causing the flame there to explode and flicker. The flow guide assembly 3 is disposed within the first arcuate groove 111 to guide the gas entering the first arcuate groove 111 from the connecting ports 113 to flow away from the first arcuate groove 111, thereby preventing the two airflows from colliding and generating high pressure.

[0049] In one embodiment, if Figure 6 As shown, the bottom of the first arc-shaped groove 111 is set lower than the bottom of the second arc-shaped groove 112, so that the gas entering the outer ring groove 11 through the connecting port 113 flows into the first arc-shaped groove 111 and flows through the guide assembly 3. The guide plate 32 is set higher than the bottom of the second arc-shaped groove 112, so that the airflow that changes direction after colliding with the partition plate 31 can flow along the guide plate 32 to the second arc-shaped groove 112, ensuring the smoothness of the airflow in the outer ring groove 11, and thus ensuring that the gas and air can be fully mixed.

[0050] Furthermore, in order to make it easier for the airflow at the air outlet of the outer ring ejector tube 2 to be guided to the first arc-shaped groove 111, the bottom of the first arc-shaped groove 111 can also be set to be stepped, that is, the two ends of the bottom of the first arc-shaped groove 111 close to the connecting port 113 are set to be lower than the middle of the bottom of the first arc-shaped groove 111, and the partition plate 31 is in contact with the middle of the bottom of the first arc-shaped groove 111.

[0051] In one embodiment, the two ends of the guide plate 32 correspond to each other and block a portion of the two communication openings 113 near the first arcuate groove 111. Extending both ends of the guide plate 32 beyond the first arcuate groove 111 and blocking a portion of the two communication openings 113 facilitates guiding the airflow after changing direction within the first arcuate groove 111 into the second arcuate groove 112, preventing the changed airflow from flowing away from the bottom of the outer annular groove 11 when passing through the communication openings 113, thereby reducing the gas flow into the second arcuate groove 112 and affecting the thorough mixing of the gas and air.

[0052] In one embodiment, the guide plate 32 and the partition plate 31 are integrally die-cast, which not only simplifies the processing technology but also facilitates the assembly of the guide assembly 3 and the base body 1 .

[0053] In one embodiment, if Figure 5 and Figure 6 As shown, first engaging structures are provided on opposite sides of the guide plate 32, and second engaging structures are provided within the side walls of the first arcuate groove 111. The first and second engaging structures cooperate to engage with each other. With the guide plate 32 secured to the first arcuate groove 111, the end of the partition plate 31, away from the guide plate 32, abuts against the bottom of the first arcuate groove 111, thereby completing the assembly of the guide assembly 3 with the base 1.

[0054] Specifically, one of the first and second engaging structures is a latching protrusion 1111, and the other is a latching groove 321. The latching protrusions 1111 are disposed on opposite sides of the first arcuate groove 111, extending from one end away from the bottom of the first arcuate groove 111 to the bottom of the groove. The latching grooves 321 are disposed on opposite sides of the guide plate 32. When installing the guide assembly 3, the two latching grooves 321 of the guide plate 32 are latched to the two latching protrusions 1111 in a one-to-one correspondence, and then the guide plate 32 is pressed downward until the partition plate 31 abuts against the bottom of the first arcuate groove 111. This completes the installation of the guide assembly 3.

[0055] Of course, in other embodiments, a locking protrusion 1111 may be provided on the guide plate 32 , and a locking groove 321 may be provided on the side wall of the first arc-shaped groove 111 .

[0056] Furthermore, the first engaging structure is located on the symmetry line of the guide plate 32, and the second engaging structure is located on the symmetry line of the two communication openings 113. This arrangement allows the guide assembly 3 to be fixed at the center of the first arcuate groove 111, ensuring that the flow rate and pressure of the gas injected into the first arcuate groove 111 by the two outer ring ejector tubes 2 are the same, thereby ensuring the uniformity and stability of the flame.

[0057] This embodiment also provides a gas stove including the above-mentioned gas stove flame distributor, which reduces the pressure of the airflow introduced into the outer ring groove 11 by the two outer ring ejector tubes 2, making the flame of the burner more uniform and stable.

[0058] In the specific contents of the above-mentioned specific implementation methods, the various technical features can be combined in any non-contradictory manner. In order to make the description concise, not all possible combinations of the above-mentioned technical features are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The specific contents of the above-mentioned specific embodiments only express several embodiments of the present invention. Although the description is relatively specific and detailed, it should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be based on the appended claims.
