NOVEL GAS HEATER

A gas heater having a heater body, a support, and a gas inlet pipe; a bottom of the heater body has a mounting cavity whose side wall has a through hole and in which the support is arranged; a mounting hole is formed on the support; an input end of the gas inlet pipe is detachably mounted to the through hole or to the mounting hole. By arranging the through hole on one side of the heater body and the mounting hole on the support, the input end of the gas inlet pipe can be selectively connected to the side surface or to the bottom surface of the heater body where it may further connect to a hose according to actual application requirements, thereby enabling relatively flexible use and more diversified application scenarios.

BACKGROUND OF THE INVENTION

The present invention relates to the technical field of stoves, and in particular to a novel gas heater.

A gas heater is a type of stove, and is mainly used in courtyards and outdoors to realize functions of heating, barbecue, decoration, atmosphere creation and the like. An independent gas heater is usually used with a table, that is to say, the gas heater is placed on the table top and is connected to an external gas cylinder by means of a hose.

In the related art, there are generally two types of interfaces for connecting a hose with a gas heater. One is a side interface, i.e., an interface arranged on a side surface of a body of a gas heater, where the hose extends across the table top and occupies part of the space of the table top, which may cause inconvenience to a user. Another type is shown in “FIRE EFFECT DEVICE AND ATTACHMENT FOR PROVIDING FIRE ON TABLE TOP” disclosed by CN205878246U, where an interface is arranged at a bottom of the gas heater; the gas heater can be used in conjunction with a table having a through hole, and the hose extends downwards through the through hole to a bottom space of the table and connects to a gas cylinder.

Apparently, these two types of interfaces are alternatives where each type is specified for a specific use. The side interface type cannot solve the problem of occupying the space of the table top, while the bottom interface type needs to be used in conjunction with a table having a through hole, so none of them can provide users with diversified uses, thus resulting in limitations.

To further explain the technical solutions of the present invention, a detailed description of the present invention is provided below through specific embodiments.

Referring toFIGS.1to7, the present invention discloses a novel gas heater, comprising a heater body1, a support2and a gas inlet pipe3.

A bottom of the heater body1is provided with a mounting cavity11, and a through hole12is formed on a side wall of the mounting cavity11;the support2is arranged in the mounting cavity11, and a mounting hole211is formed on the support; andan input end of the gas inlet pipe3is detachably mounted to the through hole12or to the mounting hole211, and the input end of the gas inlet pipe3is connected to a hose4adapted to be in communication with a gas tank/gas cylinder.

Specific embodiments of the present invention are described as follows.

The present invention also comprises a plug5. The plug5is used to block the through hole12when the input end of the gas inlet pipe3is not mounted to the through hole12.

A combustion cavity13is formed at a top of the heater body1; a wind-shielding assembly6is detachably mounted around the combustion cavity13; the wind-shielding assembly6comprises a plurality of separator plates61, which may be made of materials such as glass, thus achieving effects of shielding wind, gathering fire, concentrating heat, decorating and the like.

Furthermore, the wind-shielding assembly6further comprises a mounting seat62mounted to each corner of the combustion cavity13, as shown inFIG.4; the mounting seat62may be made of angle iron and is provided with a claw621that hooks at a corresponding corner of the combustion cavity13; the mounting seat62also comprises slots622in which adjacent separator plates61are inserted respectively, and the adjacent separator plates61inserted into the slots622are fixed and locked by grub screws63respectively; the adjacent separator plates61being fixed and locked by the grub screws63form a one whole piece with the mounting seat62. Therefore, the wind-shielding assembly6can be lifted and disposed as a whole, i.e., being lifted from the combustion cavity13or mounted around the combustion cavity13, for easier mounting and dismounting. In this embodiment, the combustion cavity13has four corners, and each corner is provided with said mounting seat62.

The support2comprises a transverse plate21, two vertical plates22, and two wing plates, wherein one end of each of the two vertical plates21is connected to a corresponding one of two ends of the transverse plate21and positioned perpendicular to the transverse plate21, and each of the two wing plates23is connected to another end of a corresponding vertical plate22and extending outwards from the corresponding vertical plate22. In other words, the support2has an U shape. The wing plates23are detachably mounted at a bottom surface of the mounting cavity11by detachable connection such as screws, and the mounting hole211is formed at a middle part of the transverse plate21.

By forming the penetrating hole14in the heater body1, mounting of the burner10can be facilitated, and after the burner10is mounted, the penetrating hole14is covered by the sealing piece40.

Further, at least one gas inlet hole103is arranged on a circumferential surface of the pipe adapter102. When the gas valve8is opened and gas is delivered to the gas outlet holes101of the burner10through the gas outlet pipe9, air is drawn into the pipe adapter102and into the burner10from said at least one gas inlet hole103due to negative pressure formed in the burner10, such that the gas and the air are better mixed to achieve full combustion.

Also, the output end of the gas outlet pipe9is provided with a nozzle91to realize acceleration of the gas into the pipe adapter102; and said at least one gas inlet hole103is arranged at a position of the circumferential surface of the pipe adapter102adjacent to the output end of the nozzle91, so as to enable better air intake by utilizing negative pressure principle.

Further, an insect-proof net50is arranged in the pipe adapter102, which can prevent mosquitoes, spiders and other small creatures from entering the pipe adapter and damaging the present invention.
