Description

Technical Field

[0001] This utility model relates to the technical field of kitchen stoves, and in particular to a stove burner cap and a gas stove including the burner cap. Background Technology

[0002] In the gas stove industry, the burner cap, as the detachable component at the very end of the burner, not only serves the function of evenly distributing the flame and providing secondary air supply, but is also one of the parts that users clean and disassemble most frequently. The actual usage scenarios for household stoves are complex and varied: on the one hand, users are eager to clean after high-temperature cooking, often immersing the burner cap directly in a sink to cool it down, and then repositioning it with considerable impact; on the other hand, some households experience accidents such as children bumping into them or pots and pans falling. The combined mechanical and thermal shocks cause the burner cap, especially the thin-walled protective shield above the ignition needle, to be highly susceptible to plastic deformation or localized warping.

[0003] In existing technologies, excessive deformation can cause the ignition gap to exceed the design range, resulting in high-voltage spark deviation, ignition delay, or even misfire. More seriously, the deformed burner cap may form a new tip discharge path between the burner cap and the ignition needle, continuously discharging and eroding the needle tip, further deteriorating ignition reliability. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defect in the prior art that the ignition distance changes due to the deformation of the burner cap, resulting in the inability to ignite, and to provide a stove burner cap and a gas stove including the burner cap.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] A stove burner cap includes a burner cap and an discharge element that cooperates with an ignition needle. The burner cap includes a burner cap body and a first protective umbrella. One end of the first protective umbrella is connected to the peripheral surface of the top of the burner cap body, and the other end of the first protective umbrella extends outward and is located directly above the ignition needle. The discharge element is connected to the first protective umbrella and protrudes from the bottom surface of the first protective umbrella. The discharge element can be raised, lowered, and moved on the first protective umbrella to adjust the distance between the discharge element and the ignition needle.

[0007] In this design, a first protective umbrella is installed on the side of the burner cap body, positioned above the ignition needle. This umbrella protects the ignition needle from liquid spillage during use, preventing it from dripping onto the needle and affecting its discharge, thus avoiding ignition failure. A movable discharge element is installed on the first protective umbrella, which works in conjunction with the ignition needle for ignition. Furthermore, if the burner cap deforms due to prolonged use, the distance between the discharge element and the ignition needle can be adjusted to ensure smooth ignition and extend the burner cap's lifespan.

[0008] Preferably, the first protective umbrella has a connection hole, the discharge element extends into the connection hole, and is movably connected to the protective umbrella through the connection hole.

[0009] In this design, a connection hole is provided in the first protective umbrella, allowing the discharge element to be placed inside the connection hole and positioned above the ignition needle. The connection hole is a through hole, allowing the discharge element to extend into and move within it, thereby adjusting the distance between the discharge element and the ignition needle.

[0010] Preferably, the connecting hole is a threaded hole that penetrates the first protective umbrella, and the discharge component is threadedly connected to the threaded hole.

[0011] In this solution, the connection hole is set as a threaded hole, which allows the discharge component to connect with the threaded hole and move through the engagement of the threads. The thread structure is simple, does not take up too much volume, and the connection effect is firm, but it does not affect the movement between the discharge component and the connection hole.

[0012] Preferably, the center line of the connecting hole coincides with the center line of the ignition needle.

[0013] In this design, the centerline of the connecting hole coincides with the centerline of the ignition needle. Therefore, the discharge element set in the connecting hole also coincides with the ignition needle in the vertical direction. When they coincide, the distance between the discharge element and the ignition needle is the shortest, resulting in better ignition performance during use.

[0014] Preferably, the discharge device includes a connecting rod and a receiving tip, the receiving tip being connected to one end of the connecting rod, the connecting rod extending into the connecting hole, and the diameter of the connecting rod being adapted to the inner diameter of the connecting hole, and the receiving tip being positioned towards the ignition needle.

[0015] In this design, the connecting rod is used to mate with the connecting hole and can move relative to the connecting hole. The receiving tip is located at one end of the connecting rod and faces the ignition needle, and is used to mate with the ignition needle to perform ignition.

[0016] Preferably, the discharge device further includes a discharge device head, which is disposed at the end of the connecting rod portion away from the receiving tip and is positioned above the first protective umbrella. At least a portion of the radial dimension of the discharge device head is larger than the diameter of the connecting hole.

[0017] In this design, the head of the discharge component allows the user to easily move the connecting rod and the receiving tip by actuating the head, thereby adjusting the distance between the receiving tip and the ignition needle. This is more convenient for the user than moving the connecting rod directly. Furthermore, the size of the discharge component head is larger than the inner diameter of the connecting hole, preventing the discharge component from detaching from the connecting hole due to wear or improper use, and ensuring that the discharge component head always remains above the first protective shield.

[0018] Preferably, the discharge element is a bolt structure, the connecting rod is provided with external threads, the inner wall of the connecting hole is provided with internal threads, and the connecting rod is threadedly connected to the connecting hole.

[0019] In this design, a bolt structure is selected as the discharge element. This structure is simple and low-cost. The bolt structure satisfies the requirements of a discharge element head with a diameter larger than the inner diameter of the connecting hole, a connecting rod with external threads, and a receiving tip that converges towards the center to form a tapered structure. A movable connection between the bolt structure and the first protective umbrella can be achieved through the threaded connection between the connecting rod and the connecting hole.

[0020] Preferably, the upper surface of the flame cap has a sloping structure, and the edge of the upper surface of the flame cap is inclined from bottom to top along a direction away from the center of the flame cap.

[0021] In this design, by tilting the edge of the flame cap upwards, the strength of the flame cap structure can be improved, effectively preventing deformation due to long-term stress during use.

[0022] Preferably, the flame cap further includes a second protective umbrella, one end of which is connected to the peripheral surface of the top of the flame cap body, and the other end of which extends outward and is located above the temperature control probe.

[0023] And / or, the upper surface of the flame cap is further provided with a bevel, the bevel being opened obliquely downward along the direction from the center of the flame cap to the edge of the flame cap.

[0024] In this design, a second protective umbrella is installed on the burner cap to protect other structures besides the ignition needle. The second protective umbrella on the temperature control probe prevents oil or liquid spills from affecting its normal operation during use. A bevel is installed on the burner cap to prevent liquid accumulation on its surface due to the upward extension of the burner cap edge, which could lead to problems with timely drainage. This downward-sloping bevel allows for timely drainage of liquid from the burner cap surface, preventing unremoved liquid from affecting its normal operation and improving reliability.

[0025] A gas stove includes an ignition needle and a burner cap as described in any of the above embodiments.

[0026] The significant advantages of this invention are as follows: A first protective umbrella is provided on the side of the burner cap body, positioned above the ignition needle. This umbrella protects the ignition needle, preventing liquid spillage during use and dripping onto it, which could affect the discharge and cause ignition failure. A movable discharge element is mounted on the first protective umbrella, allowing it to work in conjunction with the ignition needle for ignition. Furthermore, if the burner cap deforms due to prolonged use, the distance between the discharge element and the ignition needle can be adjusted to ensure smooth ignition and extend the burner cap's lifespan.

[0045] 7-burning stove Detailed Implementation

[0046] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0047] In this embodiment, as Figures 1-5 As shown, a stove burner cap 1 is provided. The stove burner cap 1 includes a burner cap 1 and an discharge element 4 that cooperates with an ignition needle 2. The burner cap 1 includes a burner cap body 11 and a first protective umbrella 12. One end of the first protective umbrella 12 is connected to the peripheral surface of the top of the burner cap body 11, and the other end of the first protective umbrella 12 extends outward and is located directly above the ignition needle 2. The discharge element 4 is connected to the first protective umbrella 12 and protrudes from the bottom surface of the first protective umbrella 12. The discharge element 4 can be raised and lowered and adjusted on the first protective umbrella 12 to adjust the distance between the discharge element 4 and the ignition needle 2.

[0048] A first protective umbrella 12 is provided on the side of the burner cap body 11, and the first protective umbrella 12 is positioned above the ignition needle 2. This protects the ignition needle 2, preventing liquid from overflowing and dripping onto it during use, which could affect the discharge of the ignition needle 2 and cause ignition failure. A movable discharge element 4 is provided on the first protective umbrella 12, which can cooperate with the ignition needle 2 for ignition. Furthermore, if the burner cap 1 deforms due to long-term use, the distance between the discharge element 4 and the ignition needle 2 can be adjusted to ensure smooth ignition and extend the service life of the burner cap 1.

[0049] In this embodiment, as Figures 4-5As shown, the first protective umbrella 12 has a connecting hole 3. The discharge element 4 extends into the connecting hole 3 and is movably connected to the protective umbrella through the connecting hole 3. By providing the connecting hole 3 in the first protective umbrella 12, the discharge element 4 can be placed in the connecting hole 3 and positioned above the ignition needle 2. The connecting hole 3 is a through hole, allowing the discharge element 4 to extend into and move within it, thereby adjusting the distance between the discharge element 4 and the ignition needle 2. In other embodiments, the movable connection between the discharge element 4 and the first protective umbrella 12 can be achieved through other structures. For example, a groove can be provided only on the side of the first protective umbrella 12 near the ignition needle 2, and the discharge element 4 can be telescopically connected to the groove. The only requirement is that the discharge element 4 can be moved relative to the first protective umbrella 12, allowing the distance between the discharge element 4 and the ignition needle 2 to be adjusted as needed.

[0050] Furthermore, such as Figure 5 As shown, the connecting hole 3 is a threaded hole that penetrates the first protective umbrella 12, and the discharge element 4 is threadedly connected to the threaded hole. By making the connecting hole 3 a threaded hole, the discharge element 4 can connect to the threaded hole and move through the engagement of the threads. The threaded structure is simple, does not occupy excessive volume, and provides a secure connection without affecting the movement between the discharge element 4 and the connecting hole 3. In other embodiments, the internal thread of the connecting hole 3 may not be provided; adjustment can be made solely through the friction between the discharge element 4 and the connecting hole 3, or by using a limiting member to fix the discharge element 4 when it is moved to the appropriate position.

[0051] Specifically, in this embodiment, such as Figure 5 As shown, the centerline of the connecting hole 3 coincides with the centerline of the ignition needle 2. Since the centerline of the connecting hole 3 coincides with the centerline of the ignition needle 2, the discharge element 4 disposed in the connecting hole 3 also coincides with the ignition needle 2 in the vertical direction. Furthermore, the distance between the discharge element 4 and the ignition needle 2 is shortest when they coincide, resulting in better ignition performance. In other embodiments, if the burner cap 1 is deformed or worn, the centerline of the connecting hole 3 may not coincide with the centerline of the ignition needle 2. In such cases, it is sufficient to adjust the discharge element 4 so that the distance between it and the ignition needle 2 meets the ignition requirements; complete coincidence is not required for use.

[0052] In this embodiment, as Figure 5 As shown, the discharge device 4 includes a connecting rod portion 42 and a receiving tip 43. The receiving tip 43 is connected to one end of the connecting rod portion 42. The connecting rod portion 42 extends into the connecting hole 3, and the diameter of the connecting rod portion 42 is adapted to the inner diameter of the connecting hole 3. The receiving tip 43 is positioned towards the ignition needle 2. The connecting rod portion 42 is used to cooperate with the connecting hole 3 and can move relative to the connecting hole 3. The receiving tip 43 is located at one end of the connecting rod portion 42 and faces the ignition needle 2, and is used to cooperate with the ignition needle 2 to perform ignition.

[0053] Furthermore, the discharge element 4 also includes a discharge element head 41, which is located at the end of the connecting rod 42 away from the receiving tip 43 and is positioned above the first protective umbrella 12. At least a portion of the radial dimension of the discharge element head 41 is larger than the diameter of the connecting hole 3. The discharge element head 41 allows the user to easily move the connecting rod 42 and the receiving tip 43 by actuating the discharge element head 41, thereby adjusting the distance between the receiving tip 43 and the ignition needle 2. This is more convenient for the user than moving the connecting rod 42 directly. Simultaneously, the portion of the discharge element head 41 being larger than the inner diameter of the connecting hole 3 prevents the discharge element 4 from detaching from the connecting hole 3 due to wear or improper use, ensuring that the discharge element head 41 remains above the first protective umbrella 12. In this embodiment, the discharge element head 41 is a circular structure; as long as the diameter of the circular structure is larger than the inner diameter of the connecting hole 3, the discharge element head 41 remains above the first protective umbrella 12. In other embodiments, the discharge element head 41 can also be a square structure, etc., as long as the above requirements are met.

[0054] Specifically, the discharge element 4 is a bolt structure, with external threads on the connecting rod 42 and internal threads on the inner wall of the connecting hole 3, and the connecting rod 42 is threadedly connected to the connecting hole 3. Choosing a bolt structure for the discharge element 4 is simple and low-cost. The bolt structure satisfies the requirements of a discharge element head 41 with a diameter larger than the inner diameter of the connecting hole 3, an externally threaded connecting rod 42, and a receiving tip 43 that converges towards the center to form a conical structure. The bolt structure and the first protective umbrella 12 can be movably connected through the threaded connection between the connecting rod 42 and the connecting hole 3. In other embodiments, other components can also be used as the discharge element 4, requiring only the discharge element head 41, connecting rod 42, and receiving tip 43.

[0055] In this embodiment, as Figures 1-3 As shown, the upper surface of the flame cap 1 has a sloping structure, and the edge of the upper surface of the flame cap 1 is inclined from bottom to top along the direction away from the center of the flame cap 1. By inclining the edge of the flame cap 1 upward, the strength of the flame cap 1 structure can be improved, effectively avoiding deformation due to long-term stress during use.

[0056] Furthermore, such as Figure 1 As shown, the flame cap 1 also includes a second protective umbrella 51. One end of the second protective umbrella 51 is connected to the peripheral surface of the top of the flame cap body 11, and the other end of the second protective umbrella 51 extends outward and is located above the temperature control probe 5. The upper surface of the flame cap 1 is also provided with a bevel 6, which is opened obliquely downward along the direction from the center of the flame cap 1 to the edge of the flame cap 1.

[0057] The burner cap 1 is equipped with a second protective umbrella 51 to protect other structures except for the ignition needle 2. The second protective umbrella 51 on the temperature control probe 5 can prevent oil or liquid spills from affecting the normal operation of the temperature control probe 5 during use. The burner cap 1 is provided with a bevel 6 to prevent liquid from accumulating on the upper surface of the burner cap 1 due to the upward extension of the edge of the burner cap 1 and being unable to be drained in time. Therefore, the downward-sloping bevel 6 can drain the liquid accumulated on the upper surface of the burner cap 1 in time, so as to avoid the liquid accumulation affecting the normal use of the burner cap 1 and improve reliability.

[0058] In this embodiment, a gas stove is also provided, characterized in that the combustion stove 7 includes an ignition needle 2 and a stove burner cap 1 as described above.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
