Description

Technical Field

[0001] The utility model relates to the technical field of cooking devices, in particular to a gas cooker. Background Art

[0002] Gas stoves cook by burning combustible gases to generate heat. The core ignition mechanism consists of an ignition pin and an ignition cap with an ignition hole. The ignition hole allows combustible gases to be ejected. The arc generated by the ignition pin ignites the ejected combustible gases, completing the ignition process.

[0003] To improve ignition success rates, the ignition pin is typically positioned close to the ignition hole. After successful ignition, the ignition hole in existing gas cooktops continues to emit combustible gas and burn. This prolonged exposure to high-temperature flames accelerates aging of the pin material, making it susceptible to damage and shortening its service life. It can also lead to decreased ignition performance or even complete failure, negatively impacting the cooking experience.

[0004] In addition, during the cooking process, liquid may overflow from the cookware (such as soup, grease, etc.). The overflow may flow down the outer wall of the cookware and seep into the ignition hole, making it difficult to clean. It may even clog the ignition hole, preventing the gas stove from igniting normally and affecting the user experience. Utility Model Content

[0031] This embodiment discloses a gas cooker for providing heat energy for cooking. Figure 1 and Figure 2 As shown, the gas stove includes a burner 1 and a shielding assembly 2, wherein a fire cover 11 and an ignition needle 12 are provided on the burner 1, an ignition hole 111 is provided on the fire cover 11, and the ignition needle 12 is located within the gas injection range of the ignition hole 111; the shielding assembly 2 includes a baffle 21 that can be raised and lowered.

[0032] When raised, the baffle 21 is positioned between the ignition pin 12 and the ignition hole 111. This prevents the flame from burning the ignition pin 12 by isolating the flame from directly contacting the ignition pin 12, thereby protecting the ignition pin 12 and extending the service life of the ignition pin 12. When lowered, the baffle 21 can at least partially withdraw from the area between the ignition pin 12 and the ignition hole 111, leaving sufficient space for the ignition pin 12 to ignite, without affecting the normal use of the gas cooker.

[0033] like Figures 1 to 4 As shown, the shielding assembly 2 also includes a control device, a drive device 22, and a lifting rod 23. The control device is connected to the drive device 22 and can start and stop the drive device 22 as needed. The baffle 21 is fixedly connected to the lifting rod 23. When the drive device 22 is activated, it can directly or indirectly drive the lifting rod 23 to rise and fall, thereby achieving the raising and lowering of the baffle 21. The drive device 22 can be, but is not limited to, a motor.

[0034] In this embodiment, the control device can be a centralized or distributed controller. For example, the controller can be a single single-chip microcomputer or a distributed plurality of single-chip microcomputers. The control program can be run in the single-chip microcomputer to control the driving device 22 to realize its function.

[0035] The specific method of the driving device 22 driving the lifting rod 23 to move up and down is not limited. In this embodiment, Figures 3 to 5 As shown, the shielding assembly 2 also includes a transmission mechanism. Specifically, the transmission mechanism includes a driving gear 24, a driven gear 25, a master-slave transmission member 26, and a driven connecting rod 27. The driving gear 24 is fixedly connected to the output shaft of the drive device 22. The master-slave transmission member 26 is connected between the driving gear 24 and the driven gear 25. The driven gear 25 is fixedly connected to the driven connecting rod 27, and the driven connecting rod 27 is connected to the lifting rod 23.

[0036] The drive device 22 can drive the lifting rod 23 up and down via the driving gear 24, the master-slave transmission member 26, the driven gear 25, and the driven connecting rod 27. Specifically, the output shaft of the drive device 22 can rotate about its own axis, the driving gear 24 can rotate synchronously with the output shaft of the drive device 22, the master-slave transmission member 26 transmits the rotation of the driving gear 24 to the driven gear 25, the driven gear 25 rotates about its own axis, and the driven connecting rod 27 can rotate synchronously with the driven gear 25. The rotation of the driven connecting rod 27 can achieve the raising and lowering of the lifting rod 23.

[0037] The specific method of the driven connecting rod 27 driving the lifting rod 23 to move up and down is not limited. In this embodiment, Figures 2 to 5As shown, one of the driven connecting rod 27 and the lifting rod 23 is provided with an external thread, and the other is provided with an internal thread. One of the driven connecting rod 27 and the lifting rod 23 is inserted into the other and the two are threadedly connected. When the driven connecting rod 27 rotates about the axis, it can drive the lifting rod 23 to move along the axis, thereby achieving the lifting and lowering of the lifting rod 23.

[0038] To prevent the cylindrical driven connecting rod 27 from being exposed, the shielding assembly 2 also includes a protective sleeve 28, which is mounted on the outside of the driven connecting rod 27. Furthermore, the protective sleeve 28 has two opposing through-holes, through which two cylindrical stoppers 281 extend from the outside of the protective sleeve 28 into the inside of the sleeve. The ends of the two stoppers 281 abut against the outer circumference of the lifting rod 23 or the driven connecting rod 27 from opposite sides, preventing radial movement of the lifting rod 23 or the driven connecting rod 27 and ensuring that the lifting rod 23 can rise and fall vertically.

[0039] Building on the above structure, the shielding assembly 2 also includes a fixed seat 29, which defines a cavity for accommodating the transmission mechanism. The drive device 22 is mounted on the fixed seat 29. The output shaft of the drive device 22 passes through the wall of the fixed seat 29 and extends into the cavity for accommodating the transmission mechanism. The output shaft of the drive device 22 is fixedly connected to the driving gear 24 in the cavity.

[0040] The fixing base 29 can protect the transmission mechanism and prevent surrounding objects or foreign matter from interfering with the operation of the transmission mechanism, making it safer to use. In addition, the fixing base 29 has mounting holes at both ends. Bolts and other connecting parts can be passed through the mounting holes to fix the fixing base 29 to a suitable position on the gas cooker, preventing the shielding assembly 2 from moving accidentally, and providing a better user experience.

[0041] The specific structure of the master-slave transmission member 26 in the transmission mechanism is not limited, as long as it can transmit the rotation of the driving gear 24 to the driven gear 25. In this embodiment, the master-slave transmission member 26 can be, but is not limited to, a belt, a chain, or a rack.

[0042] Specifically, when the master-slave transmission member 26 is a belt, one end of the belt is sleeved on the driving gear 24 and the other end is sleeved on the driven gear 25. When the driving gear 24 rotates, the belt moves with the driving gear 24, and the belt can drive the driven gear 25 to rotate in the same direction during the movement of the belt.

[0043] When the master-slave transmission member 26 is a chain, the through hole at one end of the chain is sleeved over the convex teeth of the driving gear 24, and the through hole at the other end is sleeved over the convex teeth of the driven gear 25. When the driving gear 24 rotates, the convex teeth of the driving gear 24 drive the chain to move, and the movement of the chain pulls the driven gear 25 to rotate in the same direction, which makes the transmission more stable. The chain will not slide relative to the driving gear 24 or the driven gear 25, and the transmission efficiency is higher.

[0044] When the master-slave transmission member 26 is a rack, the rack is meshed with the driving gear 24 and the driven gear 25. When the driving gear 24 rotates, the rack moves, and when the rack moves, the driven gear 25 rotates in the same direction. To prevent the rack from being in meshing with both the driving gear 24 and the driven gear 25, the rack can be clamped in a guide groove. The rack can only move along the guide groove and cannot move radially in the driving gear 24 or the driven gear 25.

[0045] Based on the above structure, the baffle 21 is curved, and the difference in curvature between the baffle 21 and the ignition hole 111 is within a set range. The specific value of this curvature difference is not limited and can be set according to the actual use. In other words, the baffle 21 is fan-shaped, and the curvature of the baffle 21 is substantially consistent with the curvature of the ignition hole 111. This effectively prevents the flame from burning the ignition needle 12 from the front and sides, thereby extending the safe use of the ignition needle 12.

[0046] The specific position of the raised baffle 21 is not limited. To prevent foreign matter such as soup and food residue from clogging the ignition hole 111, the raised baffle 21 is kept within a set range from the ignition hole 111. The specific distance is not limited, as long as it can block the ignition hole 111. The baffle 21 can provide a certain degree of sealing, preventing soup, food residue, etc. from flowing along the fire cover 11 to the ignition hole 111. This solves the problem of ignition hole 111 being blocked, ensuring smoother and safer ignition and a more stable flame.

[0047] The fire cover 11 has multiple fire holes in addition to the ignition hole 111. The baffle 21 blocks the ignition hole 111 and does not affect the normal combustion of other fire holes. Moreover, the number of fire holes is much greater than the number of ignition holes 111, so blocking the ignition hole 111 does not affect the cooking efficiency of the gas cooker.

[0048] Note that the above are only preferred embodiments of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments, and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
