Description

Technical Field

[0001] This utility model relates to the field of stove technology, and in particular to a smokeless stove. Background Technology

[0002] Stoves are used for cooking or heating and are widely used indoors or outdoors in rural areas. Various types of stoves have appeared on the market to meet different usage needs. For wood-burning stoves used in rural areas or outdoors, the smoke and dust produced by burning wood, branches, straw, etc. is relatively large. The main reason for the large amount of smoke and dust is incomplete combustion, which easily produces harmful gases such as carbon monoxide. Therefore, whether the combustion is complete or not is one of the important criteria for judging the quality of a wood-burning stove.

[0003] A search revealed a Chinese patent application with patent number CN201310360297.8, which discloses a smokeless stove, including an outer stove with an open top and an inner stove nested inside the outer stove. Both the outer and inner stoves have annular rims at their tops. However, the above technical solution does not include a mechanism that allows users to lift the stove while it is burning, which means that it is inconvenient for users to move the burning stove according to their needs. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a smokeless stove.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A smokeless stove includes an inner furnace body fitted onto the inner wall of an outer furnace body. A support ring is fixed to the top outer wall of the inner furnace body, and the bottom outer wall of the support ring is inserted into the top outer wall of the outer furnace body. A circular through groove is opened at the bottom of the outer furnace body. Multiple locking blocks are fixed to the outer wall of the outer furnace body. An L-shaped plate is inserted into the outer wall of the locking blocks. An outer shell is fixed to the outer wall of the L-shaped plate. Handles are fixed to the outer walls of both sides of the outer shell.

[0007] As a further improvement of this utility model: the outer wall of the outer shell has multiple first ventilation holes and second ventilation holes, and the outer wall of the inner furnace has multiple third ventilation holes.

[0008] As a further improvement of this utility model, the bottom outer wall of the inner furnace body has multiple fourth ventilation holes.

[0009] As a further embodiment of this utility model: a top cover is welded to the top outer wall of the outer shell, and pre-drilled holes are opened on the top cover and the bottom outer wall of the outer shell, and a friction pad is fixed on the bottom outer wall of the outer shell.

[0010] As a further improvement of this utility model: a limiting ring is fixed to the outer wall of the support ring, and the limiting ring is inserted into the top outer wall of the outer furnace body.

[0011] As a further improvement of this utility model: multiple support rods are fixed to the inner wall of the outer furnace body, and guide plates are fixed to the outer wall of the support rods.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. Users can lift the burning stove through the handle on the outer wall of the outer casing. Because there are large gaps between the inner furnace body, the outer furnace body and the outer casing, the combustion temperature inside the inner furnace body cannot be transferred to the outer wall of the outer casing. Therefore, the outer casing can shield and protect the inner furnace body while preventing the burning stove inside from burning the user, allowing the user to easily and safely lift the burning stove through the handle.

[0014] 2. External air can quickly enter the interior of the outer shell through the first ventilation hole on the outer wall of the outer shell, and then enter the gap between the outer furnace body and the outer wall of the inner furnace body through the circular through-slot at the bottom of the outer furnace body. Subsequently, it enters the interior of the inner furnace body evenly through the third and fourth ventilation holes on the outer wall of the inner furnace body, so that the airflow can fully contact the fuel inside the inner furnace body, allowing the fuel inside the inner furnace body to burn completely, thereby reducing harmful gases such as carbon monoxide and soot.

Detailed Implementation

[0022] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0023] The embodiments of this patent are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this patent, and should not be construed as limiting this patent.

[0024] Example 1: A smokeless stove, such as Figure 1-6 As shown, the inner furnace body 1 is fitted inside the outer furnace body 10. The inner furnace body 1 is characterized by having a support ring 2 fixed to the top outer wall, the bottom outer wall of the support ring 2 being inserted into the top outer wall of the outer furnace body 10, a circular through groove at the bottom of the outer furnace body 10, multiple locking blocks 16 fixed to the outer wall of the outer furnace body 10, an L-shaped plate 11 inserted into the outer wall of the locking blocks 16, an outer shell 7 fixed to the outer wall of the L-shaped plate 11, and handles 5 fixed to the outer walls of the outer shell 7 on both sides.

[0025] The outer wall of the outer shell 7 has multiple first ventilation holes 6 and second ventilation holes 8, and the outer wall of the inner furnace body 1 has multiple third ventilation holes 17.

[0026] The bottom outer wall of the inner furnace body 1 has multiple fourth ventilation holes 18;

[0027] A top cover 9 is inserted into the top outer wall of the outer shell 7. The top cover 9 and the bottom outer wall of the outer shell 7 are respectively provided with reserved holes 14. A friction pad 12 is fixed to the bottom outer wall of the outer shell 7.

[0028] First, insert the inner furnace body 1 into the outer furnace body 10. At this time, the support ring 2 at the top of the inner furnace body 1 will support the top of the outer furnace body 10, thereby supporting and limiting the inner furnace body 1 inserted into the inner wall of the outer furnace body 10. Then, align the locking block 16 at the bottom of the outer furnace body 10 with the L-shaped plate 11 on the inner wall of the outer shell 7 and insert it into the inner shell 7. The L-shaped plate 11 and the locking block 16 will support and limit the outer furnace body 10 inserted into the inner wall of the outer shell 7. Then, cover the top of the outer shell 7 with the top cover 9. Then, fuel can be added into the inner furnace body 1 to ignite the stove. Then, the user can lift the burning stove through the handle 5 on the outer wall of the outer shell 7. Since there are large gaps between the inner furnace body 1, the outer furnace body 10 and the outer shell 7, the combustion temperature inside the inner furnace body 1 cannot be transferred too much to the outer wall of the outer shell 7. Therefore, the outer shell 7 can shield and protect the inner furnace body while preventing the burning stove inside from burning the user, allowing the user to easily and safely lift the burning stove through the handle 5.

[0029] External air can quickly enter the interior of the outer shell 7 through the first ventilation hole 6 on the outer wall of the outer shell 7, and then enter the gap between the outer furnace body 10 and the outer wall of the inner furnace body 1 through the circular through-slot at the bottom of the outer furnace body 10. Subsequently, it enters the interior of the inner furnace body 1 evenly through the third ventilation hole 17 and the fourth ventilation hole 18 on the outer wall of the inner furnace body 1, so that the airflow can fully contact the fuel inside the inner furnace body 1, allowing the fuel inside the inner furnace body 1 to burn fully, thereby reducing harmful gases such as carbon monoxide and soot.

[0030] like Figure 1-5 As shown, a limiting ring 15 is fixed to the outer wall of the support ring 2, and the limiting ring 15 is inserted into the top outer wall of the outer furnace body 10; the limiting ring 15 can support and limit the support ring 2 inserted into the top of the outer furnace body 10, thereby improving the overall stability of the support ring 2.

[0031] Working principle: First, insert the inner furnace body 1 into the outer furnace body 10. At this time, the support ring 2 at the top of the inner furnace body 1 will support the top of the outer furnace body 10, thereby supporting and limiting the inner furnace body 1 inserted into the inner wall of the outer furnace body 10. Then, align the locking block 16 at the bottom of the outer furnace body 10 with the L-shaped plate 11 on the inner wall of the outer shell 7 and insert it into the inner shell 7. The L-shaped plate 11 and the locking block 16 will support and limit the outer furnace body 10 inserted into the inner wall of the outer shell 7. Then, cover the top cover 9 on the top of the outer shell 7. Then, fuel can be added into the inner furnace body 1 to ignite the furnace. Then, the user can lift the burning furnace through the handle 5 on the outer wall of the outer shell 7 and move the burning furnace to the corresponding area.

[0032] External air can quickly enter the interior of the outer shell 7 through the first ventilation hole 6 on the outer wall of the outer shell 7, and then enter the gap between the outer furnace body 10 and the outer wall of the inner furnace body 1 through the circular through-slot at the bottom of the outer furnace body 10. Subsequently, it enters the interior of the inner furnace body 1 evenly through the third ventilation hole 17 and the fourth ventilation hole 18 on the outer wall of the inner furnace body 1.

[0033] Example 2: A smokeless stove, such as Figure 6 As shown, this embodiment makes the following improvements based on embodiment 1: multiple support rods 13 are fixed to the inner wall of the outer furnace body 10, and guide plates 3 are fixed to the outer wall of the support rods 13; the guide plates 3 can clamp and limit the outer wall of the outer furnace body 10 inserted into the outer furnace body 10, thereby improving the stability of the outer furnace body 10 after it is inserted into the outer shell 7.

[0034] Working principle: The guide plate 3 can clamp and limit the outer wall of the outer furnace body 10 inserted into the outer furnace body 10.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto.
