Description

Technical Field

[0001] The invention belongs to the technical field of stove devices, and in particular relates to a windproof stove head stove device. Background Art

[0002] The upper burner of a traditional gas appliance consists of an upper cover, a lower cover and an air inlet pipe. When working, the gas flows from the air inlet pipe to the air cavity formed by the upper cover and the lower cover of the burner, waiting for the air flow to fill the entire air cavity before being discharged from the air outlet for combustion. When wind blows towards the burner, the wind will enter the air cavity from the air outlet, penetrate the air cavity and flow out from the air inlet in the other direction along with the wind direction, which can easily cause the flame to go out.

[0003] For example, a portable outdoor windproof stove head disclosed in Chinese patent CN218884069U comprises a stove head body and a folding bracket, the folding bracket is movably connected to the side wall of the stove head body, a windproof bottom plate is plugged into the folding bracket, a windproof enclosure is plugged into the windproof bottom plate, and at least three windproof enclosures are provided. A heat-insulating windproof bottom plate is provided on the stove head to protect against wind from the bottom of the stove head and has a heat-insulating effect, and a windproof enclosure is provided on the heat-insulating bottom plate to protect against wind from the side, and the folding stove head structure is easy to carry and use.

[0004] However, the windproof enclosure and the stove in the prior art are not an integrated structure, which is inconvenient to carry and place, and the structure size is large, which will also cause certain effects during use. Based on this, a windproof stove head stove device is proposed. Summary of the invention

[0005] In order to solve the above problems existing in the prior art, the present invention provides a windproof stove head stove device.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0007] A windproof stove head stove device includes a flame divider and an air pipe, the air pipe is connected to the flame divider, the flame divider includes an upper cover, a lower cover and a partition assembly, the upper cover and the lower cover cover each other and form an air cavity therein, the partition assembly is arranged in the air cavity and divides the air cavity into a plurality of air chambers, each air chamber has a plurality of air holes connected to the outside, and the partition assembly is used to prevent the air cavity from being blown through by wind.

[0008] Furthermore, it also includes a driving component, which passes through the lower cover and is connected to the partition component. The partition component is rotatably arranged in the air cavity, and a plurality of baffles are arranged at the end of the partition component. The driving component drives the plurality of baffles on the partition component to block some air holes under the action of wind.

[0009] Furthermore, the partition assembly includes a plurality of partitions, one end of the plurality of partitions are connected to each other and form a circular array based on the connection points, and a roller is provided on one side of the abutment surface between the plurality of partitions and the side wall of the lower cover.

[0010] Furthermore, the partition assembly includes a retaining ring and a plurality of partitions, wherein the plurality of partitions are arranged in a circular array on the outer wall of the retaining ring based on the center of the retaining ring, the side wall of the retaining ring is provided with an opening for connecting to each of the air chambers, and a roller is provided on one side of the abutting surface between the plurality of partitions and the side wall of the lower cover.

[0011] Furthermore, the driving assembly includes a plurality of wind shields, each of which is arc-shaped, and the plurality of wind shields are arranged in a circular array based on the center of the lower cover.

[0012] Furthermore, the driving assembly also includes a driving cavity, which is located below the air cavity. An internal gear, a transmission gear and a driven gear are arranged in the driving cavity. The internal gear is rotatably arranged in the driving cavity. A connection point is provided on the side of the driven gear, which passes through the bottom surface of the air cavity and is connected to the partition assembly. The transmission gear is respectively meshed with the internal gear and the driven gear, and the diameter of the transmission gear is smaller than the diameter of the driven gear.

[0013] Furthermore, a spring sheet is arranged on the bottom plate, one end of which is tilted, and the spring sheet is arranged on the side of the connection point close to the center of the circle, and the spring sheet is used to reset the partition assembly after rotation.

[0014] Furthermore, an ignition mechanism is detachably provided at the air hole, and the ignition mechanism includes a flint and a pulley.

[0015] The beneficial effects of the present invention are:

[0016] (1) The partition assembly is arranged inside the ignition distributor of the stove head, dividing the air cavity in the ignition distributor into multiple air chambers. The air pipe is connected at the center of the lower cover. The partition assembly divides the connecting port between the air pipe and the lower cover into several parts, so that the gas output from the air pipe to the air cavity is evenly distributed into multiple relatively independent air chambers. Even in the case of wind, the wind can only interfere with the flames of one or several air chambers on the windward side, but cannot completely penetrate the entire air cavity, thereby playing a role in isolating the wind;

[0017] (2) The partition assembly is driven to rotate a certain angle by the driving assembly. When the driving assembly is blown by the wind outside the ignition divider, the driving assembly will drive the partition assembly to rotate, and the rotation of the partition assembly will cause the baffle to rotate relatively. The rotation of the baffle will block some of the air holes. The blocking of some of the air holes will increase the gas output of other air holes that are not blocked. When the wind is strong, the number of air holes that output gas will decrease, which will increase the gas output speed and amount of the air holes that have gas output, which will increase the flame of these air holes and reduce the risk of being blown out by the wind.

[0018] (3) The flint set at the air hole will slide over the surface of the flint after the baffle is gradually reset, and the sliding of the baffle and the flint will generate sparks for secondary ignition of the stove. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0029] like Figure 1-7 As shown, a windproof stove head stove device of the present invention comprises a fire divider and an air pipe 1, the air pipe 1 is connected to the fire divider, the fire divider comprises an upper cover 3, a lower cover 2 and a partition assembly, the upper cover 3 and the lower cover 2 are mutually covered to form an air cavity 14, the partition assembly is arranged in the air cavity 14 and divides the air cavity 14 into a plurality of air chambers, each of the air chambers has a plurality of air holes 5 connected to the outside, and the partition assembly is used to prevent the flames of the air holes 5 from being blown out at the same time;

[0030] When using gas stoves outdoors or in places with low oxygen content such as plateaus, there is often wind. In this case, the flames generated by the gas ejected through the burner are easily blown out by the wind. In the prior art, a wind shield structure is generally provided on the periphery of the stove to prevent the flames from being blown out. However, providing a wind shield structure on the periphery of the stove makes it inconvenient to carry when used outdoors, and on the other hand, the stove structure is larger in size after installation, which is inconvenient to use. At the same time, in order to facilitate carrying and use, miniaturization and integration of outdoor stoves are also a development trend.

[0031] Therefore, in order to improve the windproof ability of the stove on the basis of miniaturization, a partition component is arranged inside the ignition divider of the stove head to divide the air cavity 14 in the ignition divider into multiple air chambers. The air pipe 1 is connected at the center of the lower cover 2. The partition component divides the connecting port between the air pipe 1 and the lower cover 2 into several parts, so that the gas output from the air pipe 1 to the air cavity 14 is evenly divided into multiple relatively independent air chambers, and then output to the outside through the corresponding air holes 5 on each individual air chamber and ignited by the flame. Since the interior of the ignition divider of a general stove head is a complete cavity, the wind will completely penetrate the entire air cavity 14 of the ignition divider when there is wind, causing the gas in the air cavity 14 to be blown away so that the combustion reaction of the stove cannot be continuous and the flame is extinguished. Therefore, after a partition component is set inside the ignition divider, each air chamber is relatively independent, and even in the case of wind, the wind can only interfere with the flame of one or several air chambers on the windward side, and cannot completely penetrate the entire air cavity 14, thereby playing a role in isolating the wind. After the flames of the air holes 5 corresponding to some air chambers on the windward side are extinguished, the flames of the adjacent air holes 5 that are still burning will re-ignite the extinguished air holes 5, so that the flame of the stove can continue to burn.

[0032] Furthermore, since the gas cavity 14 of the stove in the prior art is a complete whole, when the stove is used outdoors on a rugged ground, the stove cannot be placed in a completely horizontal position. At this time, since the gas is generally butane, its density is greater than that of air. It is output to the gas cavity 14 through the gas pipe 1 at the bottom and then output through the air hole 5. When the gas output is controlled to be small by the valve, due to the low pressure of the gas output, the gas flows to the lower place more easily under the action of gravity, resulting in a small gas output on the higher side and a large gas output on the lower side. The flame height and heat ignited by the air holes 5 at different heights are also different, which is not effective in some cooking scenes and has a great impact on the quality of the food after cooking. After the partition assembly is set, the partition assembly evenly divides the gas output in the gas pipe 1 into multiple parts, and each air chamber in the air cavity 14 is relatively independent. Therefore, even if the stove is in an incompletely horizontal state, the flames of different parts of the stove can be relatively consistent. In addition, a fence 7 can be set on the periphery of the stove for external wind protection.

[0033] However, although the effect of wind can be reduced to a certain extent by arranging a partition assembly in the air cavity 14, the flame of the entire stove will still be blown out when the wind is strong. In order to reduce the effect of this problem, in one embodiment, a driving assembly is further included. The driving assembly passes through the lower cover 2 and is connected to the partition assembly. The partition assembly is rotatably arranged in the air cavity 14. A plurality of baffles 13 are arranged at the end of the partition assembly. Under the action of wind, the driving assembly drives the baffles 13 on the partition assembly to block part of the air holes 5.

[0034] By arranging a driving assembly on the outer side of the lower cover 2, the driving assembly can drive the partition assembly to rotate a certain angle, and a baffle 13 is arranged on the side of the partition assembly close to the inner side of the air cavity 14. The shape of the baffle 13 is an arc that is consistent with the curvature of the inner wall of the air cavity 14. In the initial state, the baffle 13 is at a position where there are no air holes 5 in the air cavity 14. When the driving assembly is blown by wind outside the ignition divider, the driving assembly will drive the partition assembly to rotate, and the rotation of the partition assembly will cause the baffle 13 to rotate relatively. The rotation of the baffle 13 will block some of the air holes 5. Blocking some of the air holes 5 will increase the gas output of other unblocked air holes 5. By increasing the gas output of the unblocked air holes 5, the intensity of the flame can be increased. Therefore, when the wind is strong, a decrease in the number of gas output holes 5 will lead to an increase in the gas output speed and amount of the gas output holes 5 with gas output, which will increase the flames of these gas holes 5 and reduce the risk of being blown out by the wind. Although a general gas stove head can adjust the overall gas output through a gas valve, in some cooking scenarios, increasing the overall gas output will lead to a worse cooking effect. Therefore, by adjusting the number of gas output holes 5 without changing the gas output, on the one hand, the gas output is guaranteed to remain unchanged and energy loss is reduced, and on the other hand, the flame of the stove can be prevented from being blown out by the wind.

[0035] Furthermore, the partition assembly includes a plurality of partitions 6, one end of which is interconnected to form a circular array based on the connection point, and a roller 9 is provided on one side of the abutment surface of the plurality of partitions 6 and the side wall of the lower cover 2; since the partition assembly arranged in the air cavity 14 generally needs to be resistant to high temperatures, its material is metal material, which is heavy and difficult to be blown to rotate by wind force alone. Therefore, in order to reduce the friction between the partition assembly and the lower cover 2, a roller 9 is provided on the side of each partition 6 of the partition assembly abutting against the lower cover 2, so that the partition assembly can be blown and rotated even when the wind force is small.

[0036] In addition, in order to adapt to burners of different diameters and according to actual usage scenarios, the number of partitions 6 can be adapted according to the usage scenarios. The air cavity 14 can be divided into two air chambers, four air chambers or eight air chambers by the partitions 6. The air cavity 14 is divided into four air chambers for best effect.

[0037] In another embodiment, the partition assembly includes a retaining ring and a plurality of partitions 6, the plurality of partitions 6 are arranged in a circular array on the outer wall of the retaining ring based on the center of the retaining ring, the side wall of the retaining ring is provided with an opening for connecting to each air chamber, and a roller 9 is provided on one side of the abutment surface of the plurality of partitions 6 and the side wall of the lower cover 2;

[0038] Since only a plurality of partitions 6 are arranged in a circular array, when the pressure of the gas tank connected to the gas pipe 1 is insufficient, the external wind can still enter the air cavity 14 from the air hole 5 and flow in the reverse direction along the gas pipe 1, causing the flame of the entire stove to be extinguished. The retaining ring forms a secondary partition for the space in the air cavity 14, so that the openings on the retaining ring are staggered with the air holes 5 on the lower cover 2. The external wind passes through the air holes 5 and hits the outer wall of the retaining ring and becomes turbulent, thereby reducing the large amount of wind entering the interior of the retaining ring and improving the wind resistance of the stove.

[0039] In one embodiment, the driving assembly includes a plurality of windshields 4, which are all arc-shaped, and the curved surfaces of the plurality of windshields 4 are all facing the same side. The driving assembly also includes a driving cavity 15, which is located below the air cavity 14. The driving cavity 15 is provided with an internal gear 10, a transmission gear 11 and a driven gear 12. The internal gear 10 is rotatably arranged in the driving cavity 15, and a connection point is provided on the side of the driven gear 12 to penetrate the bottom surface of the air cavity 14 and is connected to the partition assembly. The transmission gear 11 is respectively meshed with the internal gear 10 and the driven gear 12, and the diameter of the transmission gear 11 is smaller than the diameter of the driven gear 12.

[0040] The whole furnace body forms a three-layer structure, namely, the air cavity 14 at the top, the driving cavity 15 at the middle layer and the wind shield 4 at the bottom. After the wind shields 4 are all facing the same side, since the wind shields 4 are arranged in a circular array around the center of the circle of the lower cover 2, from a side angle, one side of the wind shield 4 is the windward side, and the other side of the wind shield 4 is the leeward side. The curved surface that is concave is the windward side, and the curved surface that is convex is the leeward side. Under the same wind speed, the windward side is subjected to greater wind pressure, while the leeward side is subjected to less wind pressure. Therefore, a number of wind shields 4 can drive the partition assembly to rotate toward one side. After the partition assembly rotates, the baffle 13 can block part of the air holes 5, which can increase the gas output speed of the other part of the air holes 5 to avoid being extinguished in a windy environment;

[0041] At the same time, each windshield 4 passes through the bottom of the driving cavity 15 and is connected to the internal gear 10. The internal gear 10 drives the transmission gear 11 to rotate in the same direction as it, and the transmission gear 11 drives the driven gear 12 to rotate in the opposite direction to the internal gear 10. A connecting rod is arranged on the radial surface of the driven gear 12, which passes through the top of the driving cavity 15 to the air cavity 14 and is connected to the partition 6 of the partition component. After the wind drives the windshield 4, the partition component only needs to move a short distance to block part of the air holes 5. Therefore, the movement range of the connecting rod is small, rather than a completely circular rotation. Therefore, the side wall connecting the air cavity 14 and the driving cavity 15 does not need to have a large groove. On the other hand, in order to prevent the gas from penetrating from the connecting rod The position enters the driving chamber 15, causing gas leakage, so a stopper is arranged on the connecting rod in parallel with the bottom of the gas chamber 14, the size of the stopper is larger than the size of the through groove, and is used to separate the gas chamber 14 and the driving chamber 15 when the connecting rod moves, and is connected to the internal gear 10 through the wind shield 4, the internal gear 10, the transmission gear 11 and the driven gear 12 are meshed, and the driven gear 12 is connected to the partition assembly, so that when there is a strong wind outside, the wind force drives the wind shield 4 to rotate, the wind shield 4 drives the internal gear 10 to rotate, and the internal gear 10 drives the driven gear 12 to rotate, so that the baffle 13 blocks the gas hole 5, so as to achieve the same gas output while increasing the gas output speed of some gas holes 5;

[0042] On the other hand, in order for the wind shield 4 to still have sufficient driving force to drive the baffle 13 to rotate and block part of the air holes 5 when the wind force is relatively small, it is necessary to make the diameter of the transmission gear 11 smaller than the diameter of the driven gear 12. That is, when the transmission gear 11 rotates a smaller angle, the driven gear 12 can be rotated a larger angle, so that it can satisfy the action of driving the baffle 13 to block the front part of the air holes 5.

[0043] In an outdoor environment, the wind generally blows intermittently instead of continuously. In this case, the baffle 13 needs to be in a state of blocking part of the air holes 5 only when the wind blows, and in a state of not blocking part of the air holes 5 when there is no wind blowing. It is necessary to switch between these two states repeatedly. In order to facilitate use, it is necessary to reset the baffle 13 when there is no wind blowing. Therefore, in one embodiment, a spring sheet 8 is provided on the bottom plate, one end of the spring sheet 8 is tilted, and the spring sheet 8 is provided on the side of the connection point close to the center of the circle. The spring sheet 8 is used to reset the partition assembly after rotation;

[0044] The spring sheet 8 can be a memory metal sheet with elastic force. One end of the spring sheet 8 is tilted. When the wind shield 4 drives the baffle 13 to rotate, the bottom of the partition 6 is pressed on the top of the spring sheet 8 along the tilted spring sheet 8. The tilted end of the spring sheet 8 is provided with an upward bending angle to prevent the partition 6 from rotating too much and exceeding the limit range of the spring sheet 8. After the partition 6 presses the spring sheet 8, the spring sheet 8 will give the partition 6 an inclined upward thrust. Then, under the action of continuous external pressure, the partition 6 continues to press on the spring sheet 8, and the external After the wind force decreases, when the thrust of the spring sheet 8 is greater than the external wind force, the partition 6 will be pushed and reset by the spring sheet 8. In order to be able to drive the partition 6 to overcome the thrust of the spring sheet 8 and press on the spring sheet 8 when the wind force is relatively small, the spring sheet 8 needs to be set closer to the center of the circle, and the distance between the center of the circle of the connection point between the connecting rod and the partition 6 is farther than the position of the spring sheet 8 from the center of the circle, forming a labor-saving lever structure, which can drive the partition assembly to rotate under the action of smaller wind force, and the partition assembly can be reset after the wind force weakens.

[0045] Although the above structure can reduce the influence of external wind on the flame burning of the stove, the stove may be completely extinguished in extreme cases. In order to ensure the continuity of the use of the stove, it is necessary to automatically re-ignite the stove after it is extinguished. If the frequency of extinguishing is high, it is necessary to manually ignite it multiple times, which leads to inconvenience in use. In order to avoid this problem, in one embodiment, a ignition mechanism is detachably provided at the air hole 5, and the ignition mechanism includes a flint and a pulley. The flint is slidably abutted against the pulley, and the pulley protrudes from the inner side plane of the air hole 5. The baffle 13 slides and drives the pulley and the flint to slide relative to each other for secondary ignition.

[0046] In the case of wind, the partition assembly will rotate under the driving action of the wind shield 4, so that the baffle 13 will block part of the air hole 5. If the flame is completely blown out by the wind, the flint set at the air hole 5 will slide over the surface of the flint after the baffle 13 is gradually reset. Sparks are generated by the sliding of the baffle 13 and the flint for secondary ignition of the stove. The specific structure of the flint can refer to the structure of the wheel part of the sliding lighter. After the baffle 13 slides over its surface, the sparks generated will be sprayed to the outside of the air hole 5 and the ignition action will be completed. Then, the stove can be automatically ignited again after the flame is completely extinguished.

[0047] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
