AI Technical Summary
Existing gas stoves have incomplete combustion and severe heat loss, which leads to indoor pollution and has little environmental protection effect. Traditional fire hoods cannot effectively keep warm and provide heat.
A box-type smokeless heat-assisting hood is used, which is a closed structure consisting of a panel, a bottom plate, a surrounding plate and an exhaust pipe. It is made of porcelain plates and refractory insulation materials to form a closed combustion space to reduce gas usage and improve heat utilization.
It has achieved a 44% reduction in gas usage, smokeless emissions, and significantly improved heat utilization and environmental protection effects.

Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of improving the gas utilization rate and heat utilization rate of gas stoves, and more particularly to a box-type smokeless heat-assisting cover and a manufacturing method thereof. Background Art
[0002] Current gas stoves are open-burning and lack insulation. This prevents the gas from burning completely, and the heat dissipates without being fully utilized. The heat and carbon dioxide released can cause varying degrees of indoor pollution. The various fire hoods available on the market are built above the panel, leaving the fire open, providing no insulation or environmental benefits. Furthermore, they are all made of metal, which doesn't conduct heat well, nor does it retain heat, making them ineffective in assisting heating. Summary of the Invention
[0003] To address the aforementioned issues, the present invention provides a box-type smokeless heat-assisting hood. To achieve this objective, the present invention provides the following technical solution, primarily comprising: a box-type smokeless heat-assisting hood, consisting of a top panel (pot access + large flame hood), a bottom panel (air inlet + small flame hood), four surrounding panels (the back panel has exhaust holes), and an exhaust pipe. This box-type smokeless heat-assisting hood can reduce gas usage by approximately 44% while achieving the same desired effect. Furthermore, no smoke or fire is discharged externally, significantly enhancing environmental protection. BRIEF DESCRIPTION OF THE DRAWINGS
[0004] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following briefly introduces the drawings required for use in the embodiments or the description of the prior art. Obviously, the drawings described below are merely embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on the provided drawings without paying any creative work.

[0006] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by persons skilled in the art based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention. Example
[0007] A box-type smokeless heat-assisting cover, such as Figure 1 As shown, it is a box-shaped rectangular block made of porcelain plates. There are two pot openings visible to the naked eye, with two fire hoods, one above and one below, inside the openings. The pot is placed on the pot openings and the fire is burned inside. The gas is discharged to the outside through the exhaust pipe. Therefore, there are two Figure 1 , one is a three-dimensional diagram and the other is a plane diagram.
[0008] A box-type smokeless heat-assisting cover, such as Figure 2 As shown, it uses porcelain plates, which are cut into panels (rectangles and pot openings) by water jets; then a plastic bucket is used as a mold to put the panel into the pot opening; then refractory insulation materials and slurry are applied to the mold, and after solidification and demoulding, a large fire hood is obtained for use.
[0009] A box-type smokeless heat-assisting cover, such as Figure 3 As shown, it uses a ceramic plate, which is cut into a bottom plate (rectangle and air inlet) by a water jet; then a plastic bucket is used as a mold and placed in the air inlet of the bottom plate; then refractory heat-insulating materials and slurry are applied to the mold, and the mold is solidified and demoulded to obtain a small fire hood for use.
[0010] A box-type smokeless heat-assisting cover, such as Figure 4 As shown, it uses porcelain plates, which are cut into four surrounding panels by a water jet. At the same time, exhaust holes are cut on the back panel by a water jet. The four panels are then put together and the four corners are coated with refractory insulation slurry and left to solidify for use.
[0011] A box-type smokeless heat-assisting cover, such as Figure 5 As shown, it is made of metal hose.
[0012] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein, but is intended to be embodied in the widest possible manner consistent with the principles and novel features disclosed herein.
