Description

Technical Field

[0001] This utility model relates to a gas appliance, and more particularly to a portable stove. Background Technology

[0002] The function of the air damper in a gas stove is to regulate the amount of air intake to change the combustion conditions. In existing portable stoves, the air damper is installed at the bottom of the stove. When adjusting it, the stove needs to be lifted up. However, during the use of a portable stove, the outer shell is at a high temperature. Therefore, the stove needs to be turned off and allowed to cool down before adjustments can be made. This is very inconvenient and inflexible. Summary of the Invention

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a damper structure for a portable stove.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A damper structure for a portable stove includes a housing of the portable stove. A connector for connecting a gas cylinder is installed on one side of the housing. A damper is installed on the connector. A first air inlet is provided on the damper. A second air inlet is provided on the housing corresponding to the first air inlet. A spring plate is installed on the connector to make the damper abut against the side wall of the housing.

[0006] The connector is provided with a limiting boss on the outside of the housing, and a threaded part is provided on the inner end of the connector on the housing. A nut is installed on the threaded part. The damper plate and the spring plate are installed between the nut and the limiting boss. After installation, the spring plate is in a compressed state.

[0007] The spring plate is installed between the limiting boss and the outer sidewall of the housing; the damper plate is installed between the nut and the inner sidewall of the housing.

[0008] The edge of the damper plate is folded inward toward the inside of the housing 1 with an annular edge.

[0009] Both the first and second air inlets are fan-shaped holes, and there are two of each, which are symmetrically distributed.

[0010] The beneficial effects of this utility model are as follows: A connector for connecting a gas cylinder is installed on one side of the housing. An air damper is installed on the connector, and a first air inlet is provided on the air damper. A second air inlet is provided on the housing corresponding to the first air inlet. A spring plate is installed on the connector to make the air damper abut against the side wall of the housing. By rotating the connector, the air damper is rotated, thereby adjusting the overlapping area of ​​the first air inlet and the second air inlet, and thus adjusting the air intake. This allows for real-time adjustment during the use of the portable stove, and the operation is simple, convenient, and flexible. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0017] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0018] The following describes some embodiments of the present invention with reference to the accompanying drawings.

[0019] Reference Figures 1 to 4 A damper structure for a portable stove includes a housing 1. A connector 2 for connecting a gas cylinder is installed on one side of the housing 1. A damper 4 is installed on the connector 2. The damper 4 has a first air inlet 5. A second air inlet 6 is provided on the housing 1 corresponding to the first air inlet 5. A spring plate 3 is installed on the connector 2 to make the damper 4 abut against the side wall of the housing 1. By rotating the connector 2, the damper 4 is rotated, thereby adjusting the overlapping area of ​​the first air inlet 5 and the second air inlet 6, and thus adjusting the air intake. This allows for real-time adjustment during use of the portable stove, and is simple, convenient, and flexible to operate.

[0020] The connector 2 is provided with a limiting boss 7 on the outer side of the housing 1. The connector 2 is provided with a threaded part 8 on the inner side of the housing 1. A nut 9 is installed on the threaded part 8. The damper plate 4 and the spring plate 3 are installed between the nut 9 and the limiting boss 7. After installation, the spring plate 3 is in a compressed state, which makes the connector 2 tend to move along the axis, thereby abutting the damper plate 4 against the inner wall of the housing 1, preventing external air from entering the portable oven through the second air inlet 6, thus rendering the adjustment function of the damper plate 4 ineffective.

[0021] The spring plate 3 is installed between the limiting boss 7 and the outer sidewall of the housing 1; the damper plate 4 is installed between the nut 9 and the inner sidewall of the housing 1.

[0022] The friction between the nut 9 and the damper plate 4 is greater than the friction between the damper plate 4 and the inner wall of the housing 1. That is, when the connector 2 is rotated, the nut 9 rotates synchronously, and the damper plate 4 is rotated by the friction between the nut 9 and the damper plate 4.

[0023] The edge of the damper plate 4 is folded inward toward the inner side of the housing 1 with an annular edge 10, which further enhances the strength of the damper plate 4 and prevents the damper plate 4 from deforming due to the action of the spring plate 3, thereby causing a large gap between the damper plate 4 and the inner wall of the housing 1, which would affect the adjustment result of the damper plate 4.

[0024] Both the first air inlet 5 and the second air inlet 6 are fan-shaped holes, and there are two of each, symmetrically distributed (e.g., ...). Figure 3 , 4 As shown in the figure, this is a common air inlet structure. When the first air inlet 5 and the second air inlet 6 are completely overlapped, the air intake of the portable stove is the largest. When the first air inlet 5 and the second air inlet 6 are completely misaligned, the air intake of the portable stove is the smallest or there is no air intake.

[0025] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
