Description

Technical Field

[0001] The utility model relates to the field of gas flameout protection, and particularly relates to a protection component for protecting a gas flameout protection device. Background Art

[0002] A flameout protection device is a device that automatically closes the gas source when the flame of a gas stove is accidentally extinguished by reasons such as wind or soup, so as to prevent gas leakage through the gas stove. The principle of a gas stove with a flameout protection device is that when the flame is accidentally extinguished, the induction probe on the gas stove with flameout protection cannot sense the combustion signal, that is, the temperature, and the controller will automatically cut off the holding current leading to the safety valve when it does not get the signal, resulting in the closing of the safety valve, thereby cutting off the gas passage. There are two working principles for the gas stove flameout protection device: thermoelectric type and ion induction type.

[0003] The induction part of the existing flameout protection needle is mainly the needle head part. During use, the cookware may accidentally collide with the flameout protection needle of the flameout protection device, damaging the needle head of the flameout protection needle, making the flameout protection device unable to play the role of preventing gas leakage, thereby reducing the safety of using the gas stove. Generally, for household gas stoves, the flameout protection needle is protected by a stove rack, and the protection effect is poor. Summary of the Utility Model

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0005] A protection component for protecting a gas flameout protection device, including a burner head and a flameout protection needle arranged inside the burner head. A protection component is movably installed outside the flameout protection needle. The protection component includes a fixed collar and a protection cylinder. The fixed collar is fixedly sleeved outside the flameout protection needle. A bayonet is opened at the top of the fixed collar. A clamping block is arranged on the outer side of the protection cylinder, and the clamping block is movably clamped inside the fixed collar.

[0006] The further improvement of the technical solution of the utility model lies in that: the number and positions of the bayonet and the clamping block correspond to each other.

[0007] The further improvement of the technical solution of the utility model lies in that: the protection cylinder is arranged in a cylindrical hollow shape, and a rectangular opening is opened on the outer side of the protection cylinder.

[0008] The further improvement of the technical solution of the utility model lies in that: the height of the protection cylinder is higher than that of the flameout protection needle.

[0009] The further improvement of the technical solution of the utility model lies in that: the rectangular openings are arranged at equal intervals outside the protection cylinder, and at least two protection cylinders are arranged.

[0010] A further improvement of the technical solution of the present utility model lies in that: a limiting piece is arranged inside the fixed collar, and the position of the limiting piece is offset from the bayonet.

[0011] A further improvement of the technical solution of the present utility model lies in that: a groove is opened at the bottom of the clamping block, and an elastic member is movably clamped inside the groove.

[0012] A further improvement of the technical solution of the present utility model lies in that: the elastic member is a metal elastic sheet.

[0013] Due to the adoption of the above technical solution, the technical progress achieved by the present utility model compared with the prior art is as follows:

[0014] 1. The present utility model provides a protection component for protecting a gas flameout protection device. The protection component fixes and sleeves the outer tube part of the flameout protection needle through a fixed collar, and the protection cylinder corresponds to the corresponding bayonet opened at the top of the fixed collar through the clamping block at its bottom. The clamping block is snapped into the fixed collar from the bayonet, and the protection cylinder is rotated inside the fixed collar to limit the clamping block in the fixed collar, so as to protect the flameout protection needle through the protection cylinder located outside the flameout protection needle, avoid the collision between the cooking utensil and the needle tip of the flameout protection needle and cause damage, and play a role in protecting the flameout protection needle.

[0015] 2. The present utility model provides a protection component for protecting a gas flameout protection device. Through the elastic member arranged in the groove, when the clamping block is snapped into the fixed collar, the elastic member can be squeezed. Since the elastic member is a metal elastic sheet, the elastic force generated by its extrusion can push the upper end of the clamping block to abut against the inside of the fixed collar to improve the connection stability.

[0022] The following further elaborates on the present utility model in detail:

[0023] As Figures 1 to 5 shown, the present utility model provides a protection component for protecting a gas flameout protection device, including a burner head 1 and a flameout protection needle 2 arranged inside the burner head 1. A protection component 3 is movably installed outside the flameout protection needle 2. The protection component 3 includes a fixed collar 31 and a protection cylinder 32. The fixed collar 31 is fixedly sleeved outside the flameout protection needle 2. A bayonet 33 is opened at the top of the fixed collar 31. A clamping block 34 is arranged on the outer side of the protection cylinder 32. The clamping block 34 is movably clamped inside the fixed collar 31.

[0024] The fixed collar 31 is fixedly sleeved on the outer tube part of the flameout protection needle 2. The protection cylinder 32 is made to correspond to the bayonet 33 opened at the top of the fixed collar 31 through the clamping block 34 at its bottom. The clamping block 34 is inserted into the fixed collar 31 from the bayonet 33, and the protection cylinder 32 is rotated along the inside of the fixed collar 31 to limit the clamping block 34 in the fixed collar 31. Thus, the protection cylinder 32 located outside the flameout protection needle 2 protects it, preventing the collision between the cooking utensil and the needle tip of the flameout protection needle 2 and causing damage, playing a role in protecting the flameout protection needle 2.

[0025] As Figure 2 and Figure 3 shown, the number and positions of the bayonet 33 and the clamping block 34 correspond to each other.

[0026] Due to the correspondence of the number and positions of the bayonet 33 and the clamping block 34, the clamping block 34 matching the bayonet 33 is inserted into the fixed collar 31 from the bayonet 33, and the clamping block 34 is fixed and connected in the fixed collar 31 by rotating the protection cylinder 32. Thus, it is convenient for disassembly and assembly, and it is easy to replace the protection cylinder 32 when it is damaged.

[0027] As Figure 4 shown, the protection cylinder 32 is arranged in a hollow cylindrical shape, and a rectangular opening 35 is opened on the outer side of the protection cylinder 32.

[0028] The protection cylinder 32 in the shape of a hollow cylinder protects the flameout protection needle 2 inside, preventing the collision between the cooking utensil and the needle tip part of the flameout protection needle 2 and causing damage, thus playing a protective effect on the flameout protection needle 2. Through the setting of the rectangular opening 35, it is convenient for the flameout protection needle 2 to ventilate to ensure normal use.

[0029] AsFigure 1 As shown, the height of the protective cylinder 32 is set higher than that of the flameout protection needle 2.

[0030] By setting the protective cylinder 32 higher than the flameout protection needle 2, the needle part of the flameout protection needle 2 is blocked by the protective cylinder 32 to prevent damage to the needle caused by the cookware hitting the needle.

[0031] As Figure 4 shown, rectangular openings 35 are equidistantly arranged outside the protective cylinder 32, and at least two protective cylinders 32 are provided.

[0032] By arranging the rectangular openings 35 equidistantly outside the protective cylinder 32 and having at least two of them, the flameout protection needle 2 located inside the protective cylinder 32 is penetrated through the rectangular openings 35, ensuring the stable and normal induction use of the needle part of the flameout protection needle 2.

[0033] As Figure 3 shown, a limiting piece 36 is arranged inside the fixing collar 31, and the position of the limiting piece 36 is offset from the bayonet 33.

[0034] Through the arrangement of the limiting piece 36, with the limiting piece 36 located inside the fixing collar 31 and its position corresponding to that of the bayonet 33 and the clamping block 34, when the clamping block 34 rotates inside the fixing collar 31, the limiting piece 36 limits it to ensure that the clamping block 34 rotates and abuts against the limiting piece 36, thereby determining that the clamping block 34 rotates to the outermost end to ensure that the protective cylinder 32 is installed in place.

[0035] As Figure 5 shown, a groove 37 is formed at the bottom of the clamping block 34, and an elastic member 38 is movably clamped inside the groove 37.

[0036] The elastic member 38 is a metal elastic sheet.

[0037] Through the elastic member 38 arranged in the groove 37, when the clamping block 34 is inserted into the fixing collar 31, the elastic member 38 is squeezed. Since the elastic member 38 is a metal elastic sheet, the elastic force generated by its squeezing pushes the upper end of the clamping block 34 to abut against the inside of the fixing collar 31, so as to improve the connection stability.

[0038] Next, the working principle of the protection component for protecting the gas flameout protection device will be specifically described.

[0039] As Figures 1 to 5As shown in the figure, it is sleeved on the outer tube part of the flameout protection needle 2 through the fixed collar 31. The protective cylinder 32 corresponds to the corresponding bayonet 33 opened at the top of the fixed collar 31 through the clamping block 34 at its bottom. The clamping block 34 is snapped into the fixed collar 31 from the bayonet 33, and the protective cylinder 32 is rotated along the inside of the fixed collar 31. The clamping block 34 is driven by the protective cylinder 32 to rotate inside the fixed collar 31. The rotation of the clamping block 34 abuts against the limiting piece 36 and stops. At this time, the protective cylinder 32 is sleeved on the outside of the flameout protection needle 2. Since the protective cylinder 32 is arranged higher than the flameout protection needle 2, the direct collision of the cookware with the needle part of the flameout protection needle 2 is avoided, and the protective effect is achieved through the shielding of the protective cylinder 32. The flameout protection needle 2 is kept in communication with the outside through the rectangular opening 35 arranged on the outside of the protective cylinder 32 to ensure the normal use of the flameout protection needle 2. At the same time, during installation, the elastic member 38 can be snapped into the groove 37, and the elastic member 38 abuts against the bottom inside the fixed collar 31 to generate deformation. The stability of the clamping block 34 inside the fixed collar 31 is improved through the elastic force of the elastic member 38.

[0040] The above generally describes the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
