Description

Technical Field

[0001] This application relates to the field of heating technology, and more specifically, in particular to an improved outdoor gas heater. Background Technology

[0002] A gas heater is a device that provides warmth by igniting gas supplied from a gas cylinder to the burner. The heater consists of several parts, including a base assembly, a burner, and a support rod. In current technology, ignition is typically achieved by turning on a gas valve knob, then the user presses the knob with one hand to keep the gas flowing while simultaneously pressing the ignition device with the other hand to ignite the gas in the burner. This two-handed operation is inconvenient. Utility Model Content

[0003] The purpose of this application is to address the shortcomings of the existing technology and propose an improved outdoor gas heater that is easy to ignite.

[0004] To achieve the above objectives, this application proposes an improved outdoor gas heater, including a burner assembly, a support rod for supporting the burner assembly, and a base assembly for supporting the support rod. The heater also includes a valve assembly, which is fixedly connected to the burner assembly. The burner assembly includes an ignition plate, and the valve assembly includes a gas valve, a knob, and an ignition assembly. The knob can open or close the gas valve. When the gas valve is open, gas flows to the ignition plate. The knob and the ignition assembly are linked, and the ignition assembly emits an electric spark to the ignition plate.

[0005] The gas valve includes a valve stem, and the knob is fixed to the valve stem. The knob controls the opening or closing of the gas valve through the valve stem. The ignition assembly includes an igniter, and the igniter is linked to the valve stem.

[0006] The igniter is fixed to the gas valve; or the igniter and the gas valve are integrally formed.

[0007] The burner assembly includes a first mesh base and an indicator plate. The ignition plate is fixed to the first mesh base, and the indicator plate is located below the first mesh base. The indicator plate has a valve-closed position indicator, a maximum flame position indicator, and a minimum flame position indicator. When the knob is pointed to the valve-closed position indicator, the gas valve is closed. When the knob is pointed to the maximum flame position indicator, the gas valve has the maximum flow rate. When the knob is rotated between the maximum flame position indicator and the minimum flame position indicator, the flow rate of the gas valve can be adjusted.

[0008] The knob can be rotated 90 degrees from the valve-closed position mark to the maximum fire position mark, and the knob can be rotated 125 degrees to the minimum fire position mark.

[0009] When the knob is rotated between 45 and 90 degrees from the valve-closed position mark to the maximum fire position mark, the flow rate of the gas valve remains at its maximum value.

[0010] When the knob is rotated between 65 and 85 degrees from the valve-closed position indicator towards the maximum fire position indicator, the knob causes the valve stem to contact the igniter switch. When the knob is rotated between 85 and 90 degrees from the valve-closed position indicator towards the maximum fire position indicator, the igniter completes ignition.

[0011] When the knob is rotated to the maximum flame position mark, the knob is pressed towards the gas valve, which drives the valve stem to move. The valve stem then drives the igniter switch to complete the ignition.

[0012] The burner assembly also includes a small mesh and a second mesh holder. The upper end of the small mesh is fixed to the first mesh holder, and the lower end of the small mesh is fixed to the second mesh holder. The identification plate is located between the first mesh holder and the second mesh holder. The igniter is located within the space enclosed by the identification plate and the small mesh. The gas valve is located within the space enclosed by the identification plate and the small mesh.

[0013] The length of the gas valve in the left-right direction is between 100mm and 140mm, the height of the gas valve in the up-down direction is between 80mm and 110mm, the width of the gas valve in the front-back direction is between 35mm and 50mm, and the height of the gas valve is less than the height of the small mesh.

[0014] Beneficial effects:

[0015] As can be seen from the above technical solutions, this application has the following advantages compared with the prior art:

[0016] 1. When the user ignites, the knob and the ignition component work together. Using the knob opens the gas valve, allowing gas to flow to the ignition plate. The knob also drives the ignition component to generate an electric spark to ignite the gas near the ignition plate, allowing the user to complete the ignition for heating with just one hand.

[0017] 2. The igniter is fixed to the gas valve, which allows the igniter to be placed inside the small mesh. The structure of the igniter and the gas valve is more compact and occupies less space. At the same time, it facilitates the switching contact and linkage between the valve stem and the igniter, improving convenience.

[0018] 3. With the knob in the direction from the valve-closed position mark to the maximum flame position mark, the gas flow of the gas valve reaches its maximum when the knob is rotated 45 degrees. If the knob continues to rotate, the valve stem will drive the igniter to complete the ignition. Through the foolproof design, the gas valve is kept in the open state before the igniter is activated, reducing the possibility of the gas valve closing when the igniter is working.

Detailed Implementation

[0026] The embodiments of this application will now be clearly and completely described with reference to the accompanying drawings.

[0027] Please refer to Figures 1 to 5 As shown, an improved outdoor gas heater of this application includes a burner assembly 1, a support rod 2 and a base assembly 3. One end of the support rod 2 is fixed to the base assembly 3, and the other end of the support rod 2 is fixed to the burner assembly 1. The base assembly 3 is located below the burner assembly 1.

[0028] The burner assembly 1 includes a combustion mesh 11, an ignition plate 12, a first mesh holder 13, a small mesh 14, a second mesh holder 15, and an identification plate 16. Within the combustion mesh 11 of the ignition plate 12, the first mesh holder 13 supports and fixes the lower part of the combustion mesh 11. The first mesh holder 13 is directly fixed to the ignition plate 12 via a connecting structure. The second mesh holder 15 is located below the first mesh holder 13. The upper end of the small mesh 14 is fixed to the first mesh holder 13, and the lower end of the small mesh 14 is fixed to the second mesh holder 15. The second mesh holder 15 supports the small mesh 14, and the small mesh 14 supports the first mesh holder 13. The small mesh 14 is located between the first mesh holder 13 and the second mesh holder 15, and the identification plate 16 is located between the first mesh holder 13 and the second mesh holder 15. The identification plate 16 can be directly or through a connecting structure fixedly connected to the small mesh 14; or, the identification plate 16 can be directly or through a connecting structure fixedly connected to the large mesh holder; or, the identification plate 16 can be directly or through a connecting structure fixedly connected to the small mesh 14. The end of the support rod 2 away from the base assembly 3 is fixedly connected to the lower end of the small mesh 14 seat, and the support rod 2 supports the furnace head assembly 1 through the small mesh 14 seat.

[0029] The heater also includes a valve assembly 4, which is partially or entirely fixed to the burner assembly 1. The valve assembly 4 includes a gas valve 41, a knob 42, and an ignition assembly 43. The gas valve 41 is partially or entirely located inside the small mesh 14. The gas valve 41 includes a valve stem 411. The knob 42 is fixed to the valve stem 411 of the gas valve 41. The knob 42 opens or closes the gas passage of the gas valve 41 via the valve stem 411, and can also adjust the size of the gas passage. The ignition assembly 43 is fixed to the valve assembly 4 directly or indirectly; or, the ignition assembly 43 is directly or indirectly fixed to the burner assembly 1; or, the ignition assembly 43 is partially fixed to the burner assembly 1 and partially fixed to the valve assembly 4, directly or indirectly. Specifically, the ignition assembly 43 includes an igniter 431 and an ignition needle 432, which are connected by a wire. The igniter 431 is fixed to the gas valve 41, and the ignition needle 432 is fixed to the burner assembly 1. When the igniter 431 is working, the generated current flows along the guide to the ignition needle 432, and an electric spark is generated between the ignition needle 432 and the ignition plate 12, thereby igniting the gas near the ignition plate 12. It can be understood that the igniter 431 and the gas valve 41 are integrally formed.

[0030] When knob 42 is rotated, the gas flow rate of gas valve 41 varies between 0 and its maximum value. The indicator plate 16 has indicators for the closed valve position, maximum flame position, and minimum flame position. Knob 42 has directional indicators, allowing it to point to these positions. When knob 42 is rotated to the closed valve position, the gas flow rate of gas valve 41 is completely shut off. When knob 42 is rotated to the maximum flame position, the gas flow rate of gas valve 41 is at its maximum. When knob 42 is rotated to the minimum flame position, the gas flow rate of gas valve 41 maintains the minimum position to prevent the flame of ignition plate 12 from extinguishing. In this embodiment, the closed valve position indicator is located directly above knob 42, the maximum flame position indicator is located directly to the left of knob 42, and the minimum flame position indicator is located diagonally below knob 42. Specifically, knob 42 reaches the maximum flame position when rotated 90 degrees counterclockwise from the closed valve position, and reaches the minimum flame position when rotated 125 degrees counterclockwise from the maximum flame position. That is, knob 42 can drive valve stem 411 to rotate to adjust the flow rate of gas valve 41. Knob 42 can rotate between the valve closed position mark and the maximum fire position mark. Knob 42 can rotate between the maximum fire position mark and the minimum fire position mark.

[0031] The knob 42 is linked to the igniter 431 of the ignition assembly 43. When the knob 42 is rotated within 15 degrees above or below the maximum flame position, the valve stem 411 contacts the switch of the igniter 431, causing the igniter 431 to start. Since the gas valve 41 is already open when the knob 42 is rotated from the closed valve position to the maximum flame position, the igniter 431 can directly ignite the gas at the ignition plate 12, causing the heater to start working. Specifically, when the knob 42 is rotated counterclockwise from the closed valve position between 65 and 90 degrees, the gas valve 41 maintains the maximum gas flow. At the same time, when the knob 42 is rotated between 65 and 85 degrees, the valve stem 411 contacts the switch of the igniter 431. When the knob 42 drives the valve stem 411 to continue rotating 85 to 90 degrees, the valve stem 411 drives the igniter 431 to complete the ignition. In this embodiment, the igniter 431 is based on piezoelectric ignition, but it can be replaced with pulse ignition according to the needs of those skilled in the art. It is understandable that when knob 42 is rotated from the closed position to the maximum value position, the gas flow rate of gas valve 41 is directly at its maximum at the midpoint between the closed and maximum value positions. For example, when knob 42 is rotated from the closed position to the maximum value position, if knob 42 is rotated 45 degrees, the gas flow rate of gas valve 41 reaches its maximum value. Before knob 42 is rotated 40 degrees, the gas flow rate of gas valve 41 is 0. Between 40 degrees and 45 degrees, the gas flow rate of gas valve 41 goes from 0 to its maximum value. Between 45 degrees and 90 degrees, the gas flow rate of gas valve 41 remains at its maximum value. The rotation angle of knob 42 can be selected from 45 degrees as needed, such as 50 degrees, 55 degrees, etc., but it must be ensured that the gas flow rate of gas valve 41 remains at its maximum value before the valve stem 411 contacts the igniter 431 switch. Specifically, knob 42 drives valve stem 411 to rotate, and valve stem 411 is linked with igniter 431 to enable igniter 431 to work.

[0032] The specific operation of the knob 42 and igniter 431 in linkage ignition is as follows: When the knob 42 is in the closed valve position, the user can press the knob 42 with one hand, and then the knob 42 can be rotated from the closed valve position to the maximum flame position. When the knob 42 is rotated 75 degrees counterclockwise from the closed valve position, the valve stem 411 contacts the igniter 431 switch. Continuing to rotate the knob 42 to the maximum flame position will complete the piezoelectric ignition of the igniter 431, causing the ignition needle 432 to emit an electric spark to ignite the gas near the ignition plate 12. When the knob 42 is rotated between the closed valve position and the maximum flame position, the knob 42 needs to be pressed and rotated at the same time. This design can reduce the ignition caused by accidental contact of the knob 42, improve the safety of the heater, and at the same time reduce the gas leakage caused by accidental contact of the knob 42. It is understandable that knob 42 can also be ignited in another way, as follows: When knob 42 is in the closed position, the user does not need to press it; they can directly rotate it from the closed position to the maximum value position. When knob 42 is rotated 75 degrees counterclockwise from the closed position, valve stem 411 contacts the igniter 431 switch. When knob 42 is rotated between 75 and 95 degrees, pressing knob 42 can drive valve stem 411, which in turn drives the igniter 431 switch, completing piezoelectric ignition. This causes ignition needle 432 to emit an electric spark to ignite the gas near ignition plate 12. In this embodiment, the first, safer operating method is used.

[0033] The burner assembly 1 also includes a fixing bracket 161. The marking plate 16 is fixed to or adjacent to the fixing bracket 161. The fixing bracket 161 is directly or indirectly fixed to the first mesh seat 13, and the fixing bracket 161 is located below the first mesh seat 13. The fixing bracket 161 is used to fix the valve assembly 4, which improves the stability of the gas valve 41.

[0034] The main body of the gas valve 41 is located within the space enclosed by the small mesh 14 and the label plate 16. A portion of the valve stem 411 is located inside the space enclosed by the small mesh 14 and the label plate 16, while another portion of the valve stem 411 is located outside the label plate 16, meaning the valve stem 411 passes through the label plate 16. The portion of the valve stem 411 located outside the label plate 16 is fixedly connected to the knob 42. Definition: The combustion valve located inside the space enclosed by the small mesh 14 and the label plate 16 is the first part, and the portion located outside the label plate 16 is the second part. That is, the first part of the combustion valve is fixedly connected to the first mesh seat 13 of the burner assembly 1 via the fixing bracket 161, and the second part of the combustion valve is fixedly connected to the knob 42.

[0035] The diameter of the small mesh 14 is between 90mm and 120mm; excluding the connecting parts at the top and bottom of the small mesh 14, the height of the small mesh 14 is between 125mm and 155mm; the height of the panel is between 125mm and 155mm; as... Figure 4The gas valve 41 has a length between 100mm and 140mm in the left-right direction, a height between 80mm and 110mm in the up-down direction, and a width between 35mm and 50mm in the front-back direction. In this embodiment, the small mesh 14 has a diameter of 106mm. Excluding the connecting parts at the top and bottom of the small mesh 14, the height of the small mesh 14 is 142mm. The height of the marking plate 16 is also 142mm. On the same horizontal plane, the longest distance between the marking plate 16 and the small mesh 14 is 125mm. The height of the gas valve 41 is 96mm, the length of the first part of the gas valve 41 is less than 97mm, and the total length of the gas valve 41 is 118mm. That is, the length of the first part of the gas valve 41 is less than the longest distance between the marking plate 16 and the small mesh 14, the height of the combustion valve is less than the height of the small mesh 14, and the first part of the combustion valve can be placed within the space enclosed by the marking plate 16 and the small mesh 14.
