Description

Technical Field

[0001] This utility model relates to the technical field of heating equipment, specifically to a portable gas-fired radiant heater. Background Technology

[0002] A heater is a device used for heating. Heaters are widely used in various civil and public buildings, including residences, offices, hotels, shopping malls, hospitals, schools, train carriages, mobile heating systems, and temporary housing. Currently, some heaters on the market generally contain an energy storage tank, a pressure reducing valve that works with the tank, and a connector at the valve's outlet; these components form the various stages of the energy supply process.

[0003] Existing portable gas-fired radiant heaters typically only have one gas cylinder. When the gas in the cylinder runs out, it needs to be replaced so that the heater can continue to operate. Therefore, it is necessary to store spare or empty gas cylinders, and it is inconvenient to carry the spare cylinder when using it outdoors.

[0004] Meanwhile, because the gas tank is placed vertically to fit the heater's casing, this placement often requires the gas tank to be tilted outwards for easy replacement due to space constraints inside the heater. However, most heaters currently have fixed pressure-reducing valves. Therefore, the pressure-reducing valve used with the gas tank needs a flexible adjustment mechanism. Furthermore, the valve must prevent gas leakage during adjustment. Utility Model Content

[0045] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0046] like Figure 1-10 As shown in the following embodiment, a portable gas-fired radiant heater is disclosed.

[0047] Example 1

[0048] A portable gas-fired radiant heater, comprising,

[0049] A housing 100 having a gas burner 200, one end face of the housing 100 being a heating surface;

[0050] The connector assembly 300 is installed inside the housing 100 and connected to the gas burner 200;

[0051] A gas cylinder 400 is detachably connected to the connector assembly 300 for supplying gas to the gas burner 200;

[0052] A spare gas cylinder of 500 is stored inside the housing of 100, and the gas pipe can be replaced.

[0053] The back of the housing 100 is provided with an openable back panel 110. The spare gas cylinder 500 and the gas cylinder 400 are located inside the back panel 110. By opening the back panel 110, the spare gas cylinder 500 can be removed and the gas cylinder 400 can be replaced.

[0054] The above is the basic scheme of this embodiment.

[0055] Specific reference Figure 1 As shown, the front end of the housing 100 is set as the heating surface, and the heating surface of the gas burner 200 faces the heating surface; the gas cylinder 400 and the spare gas cylinder 500 are both installed upright inside the housing 100, and the connector assembly 300 connects the gas cylinder 400 and the gas burner 200 through a pipeline. A control button 101 is provided on the upper end of the housing 100, and a handle 102 is provided on the housing 100 for easy carrying.

[0056] To facilitate the replacement of the spare gas cylinder 500, in this embodiment, the back plate 110 is detachable and mounted on the housing 100. At the same time, the fittings of the connector assembly 300 are all located on the front side of the gas cylinder 400. That is to say, when the back plate 110 is opened, the gas cylinder 400 and the spare gas cylinder 500 can be directly exposed, making it convenient for the user to remove the spare gas cylinder 500 and the gas cylinder 400 for replacement.

[0057] Specifically, the connection between the back plate 110 and the box 100 is as follows: one side of the back plate 110 is pivotally connected to the back of the box 100, and the other side is connected to the back of the box 100 through the adsorption member 1.

[0058] Reference Figure 2 As shown, the back plate 110 has two sides, one of which is a hinge side 11. Short shafts 111.1 are provided on the upper and lower end faces of the hinge side 11. The housing 100 has shaft holes that mate with the short shafts 111.1. The short shafts 111.1 are inserted into the shaft holes, allowing the back plate 110 to rotate around the axis of the short shafts 111.1, thus opening the other side. The other side of the back plate 110 is a suction side, and a first suction element 1, such as a magnet, is embedded on the inner end face of the suction side. The housing 100 has a second suction element 1 that mates with the suction element 1. When the suction side of the back plate 110 and the housing 100 are closed, the two suction elements 1 attract each other, thus connecting the suction side to the housing 100.

[0059] To facilitate user operation of the back panel 110, an operation recess 112 is provided on the adsorption side. The operation recess 112 and the back of the box 100 form an operation groove that allows a person to reach in.

[0060] To prevent damage or leakage caused by displacement of the internal gas cylinder 400 and spare gas cylinder 500 during the movement of the heater, in this embodiment, a connector 320 bracket and a gas cylinder bracket 700 are fixed inside the housing 100. The connector 320 bracket suspends the connector assembly 300, and the gas cylinder bracket 700 suspends the spare gas cylinder 500.

[0061] Specific reference Figure 3 As shown, the gas tank support 700 is a U-shaped support. The U-shaped support includes two vertical side plates and a suspension plate connected to the lower end of the side plates. The upper end of the side plates is fixed to the top of the box 100 by a bending piece. The suspension plate is provided with a notch 701, and the interface of the spare gas tank 500 can be inserted into the notch 701 for suspension.

[0062] The connector 320 bracket is an N-type bracket with an opening direction opposite to that of the gas tank bracket 700. The connector assembly 300 is installed in the space between the two side plates.

[0063] Specifically, the connector assembly 300 includes a pressure reducing valve 310 and a connector 320 that connects the pressure reducing valve 310 to the gas burner 200. The pressure reducing valve 310 is mounted on the bracket of the connector 320 and can rotate around a first axis on the bracket of the connector 320 to drive the gas cylinder 400 to rotate out.

[0064] To facilitate the replacement of the gas cylinder 400, when removing the gas cylinder 400, it is necessary to first rotate the gas cylinder 400 out to a position that is easy for manual operation, and then rotate it off the pressure reducing valve 310; in the original upright state, due to the limited space inside the box 100, it is inconvenient for manual operation.

[0065] Reference Figure 4 and Figure 5 As shown, a rotating space is formed between the two sides of the connector 320 bracket. The pressure reducing valve 310 is installed in the rotating space and is pivotally connected to the two sides. When replacing the gas cylinder 400, the gas cylinder 400 is rotated out, which drives the pressure reducing valve 310 to rotate together, so that the gas cylinder 400 is rotated out of the space of the housing 100. At this time, the gas cylinder 400 and the pressure reducing valve 310 are still connected. The user can operate the gas cylinder 400 in the external space to rotate it and unscrew it from the pressure reducing valve 310.

[0066] Specifically, in this embodiment, one side of the pressure reducing valve 310 is connected to the connector 320 bracket via a rotating rod, and the other end is equipped with a rotating head 330. The side of the connector 320 bracket is provided with a bayonet 601 to snap the rotating head 330 into place, so that the rotating head 330 can rotate within the bayonet 601.

[0067] In addition, to prevent the pressure reducing valve 310 from coming off the connector 320 during rotation, in this embodiment, the connector assembly 300 is provided with a guide structure to limit the position of the pressure reducing valve 310 during rotation.

[0068] Specific reference Figure 6 and Figure 7 As shown, the connector 320 is connected to the rotating head 330, and a guide post 2 is axially inserted through the connector 320. The inner end of the guide post 2 extends into the connector 320. An annular groove is provided on the outer periphery of the rotating head 330 at the part located inside the connector 320. The guide post 2 extends into the annular groove to limit the rotation of the rotating head 330.

[0069] Based on the above settings, when the rotating head 330 rotates with the pressure reducing valve 310, the guide post 2 limits the rotating head 330, so that the rotating head 330 can only rotate around the first axis and cannot be dislodged from the connector 320.

[0070] In this embodiment, a sealing ring 3 is provided on the rotating head 330, forming a seal between it and the inner wall of the connector 320.

[0071] Example 2

[0072] This embodiment is an improvement on embodiment 1. Its purpose is to add damping to the connector assembly 300 so that the gas cylinder 400 can stop at the rotated position after being rotated out, making it easier for the user to replace the gas cylinder 400. The specific implementation method is as follows:

[0073] The pressure reducing valve 310 is provided with a rotating head 330, which can rotate on the bracket of the connector 320; a damping structure is provided between the rotating head 330 and the bracket of the connector 320.

[0074] When the gas cylinder 400 is rotated out by the user, it drives the pressure reducing valve 310 and the rotating head 330 to rotate out together. At this time, a damping force is generated between the rotating head 330 and the bracket of the connector 320, which allows the gas cylinder 400 to stop in the rotated position without the operator having to support the gas cylinder 400, thus saving more effort.

[0075] Specifically, the damping structure includes a pad 800, the two end faces of which respectively contact the bracket of the connector 320 and the rotating head 330.

[0076] Specific reference Figure 8 As shown, the side of the connector 320 bracket is located outside the rotating head 330. The end of the rotating head 330 is set as a stepped structure, and the spiral part extends into the connector 320 through the bayonet 601. The female part connected to the spiral part is located on the other side of the side, and the outer diameter of the female part is larger than the outer diameter of the spiral part.

[0077] The pad 800 is located between the female part and the side of the connector 320 bracket, and is fitted onto the spiral part, with its two ends contacting the end face of the female part and the end face of the side part, respectively.

[0078] Preferably, the pad 800 is made of rubber.

[0079] Furthermore, in order to increase the damping force of the pad 800, in this embodiment, the pad 800 is provided with a plurality of receiving grooves 801 along the axial direction, and a spring 4 is provided in the receiving groove 801. A top bead 5 is held on the outer side of the spring 4, and the top bead 5 abuts against the bracket of the connector 320 or the rotating head 330.

[0080] Specific reference Figure 9As shown, the diameter of the groove opening of the receiving groove 801 is smaller than the inner diameter. The spring 4 is located inside the receiving groove 801, and the top bead 5 is held by the spring 4, so that the end of the top bead 5 extends out of the groove opening and holds against the end face of the rotating head 330 or the connector 320 bracket. In this embodiment, one side of the groove opening preferably faces the rotating head 330, that is, the top bead 5 holds against the end face of the mother part.

[0081] In this embodiment, the accommodating groove 801, spring 4, and top ball 5 can be arranged in multiple ways along the circumferential direction, and the elastic force of the spring 4 in each accommodating groove 801 is different and can increase along the rotation direction.

[0082] In other words, the greater the rotation angle of the gas cylinder 400, the greater the holding force on the rotating head 330, and thus the greater the damping force.

[0083] Example 3

[0084] This embodiment is an improvement on embodiment 1, and its purpose is to add functions to the heater. The specific implementation method is as follows:

[0085] A heat insulation mesh cover 900 is detachably installed on the heating surface of the box 100.

[0086] Specific reference Figure 10 As shown, the heat insulation mesh cover 900 is a mesh cover structure formed by welding multiple steel wires arranged horizontally and vertically. The housing 100 is provided with mounting holes 103 that can accommodate the insertion of the ends of the steel wires. The steel wires on the heat insulation mesh cover 900 are inserted into the mounting holes 103 to cover the heating surface.

[0087] Thus, when the housing 100 is in a reclining position, the heat insulation mesh cover 900 is on top and can be used as a heating surface. Containers can be placed on the heat insulation mesh cover 900 for heating food or liquids, giving the heater the function of a gas stove.

[0088] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
