DETAILED DESCRIPTION

[0035] In order to make the technical means, creation characteristics, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific drawings.

[0036] As shown in Figure 1 A gas heater, comprising a furnace body 1, a furnace head disc 2, a furnace head 3, an air disturbance assembly 12 and a gas source 8.

[0037] The furnace body 1 is hollow inside, and an installation groove is formed on the inner bottom plate, and a replaceable gas source 8 is fixedly installed through the installation groove. In this embodiment, the gas source 8 is specifically a gas tank. An igniter is connected between the gas source 8 and the furnace head 3. The furnace head disc 2 is provided with an igniter 11. The furnace body 1 is open at the top. The furnace head disc 2 is installed at the opening. The installation shell 201 is formed by the upward protrusion of the middle part of the furnace head disc 2. The furnace head 3 is arranged on the furnace head disc 2 as a heat source.

[0038] Further, the air disturbance assembly 12 comprises a motor 7 and a fan blade 4. The fan blade 4 is arranged above the installation shell 201 and is driven to rotate by the motor 7. The outer ring of the furnace head disc 2 is provided with a mesh cover 5. The top cover 10 is arranged above the mesh cover 5. The mesh cover 5 is inserted and installed in the inner ring groove 202. The hot air flow generated by the furnace head 3 flows upward under the disturbance of the fan blade 4, is blocked by the top cover 10 and then diffuses to the surrounding through the mesh cover 5.

[0039] In the embodiment, the heating cavity 13 is formed between the burner disc 2, the mesh cover 5 and the top cover 10. During use of the heater, the gas source 8 supplies gas to the burner 3. The gas in the gas source 8 is ignited by the burner 3 to generate a flame, which heats the surrounding air to generate a hot air flow. At the same time, the fan blade 4 rotates to disturb the air around the burner 3, which is finally dissipated through the dense through holes of the mesh cover 5. In combination with the heat radiation generated by the open flame in the burner 3, the heating is achieved.

[0040] Further, the furnace body 1 is provided with an opening for placing the gas source 8 inside the furnace body 1. The opening is provided with an opening and closing door 101. When the gas in the gas source 8 is used up, the gas source 8 can be taken out by opening the opening and closing door 101, and a new gas source 8 can be quickly replaced for use.

[0041] Further, as shown in Figure 2 , the burner disc 2 further comprises an inner ring groove 202 extending from the outer ring of the mounting shell 201 to the direction of the convex direction of the mounting shell 201. The burner 3 is arranged in the inner ring groove 202. The inner ring groove 202 extends outwardly to an outer ring groove 203 in the opposite direction of the opening. The burner disc 2 is mounted on the opening above the furnace body 1 through the outer ring groove 203. The inner ring groove 202 is used to accommodate the burner 3. The flame generated by the burner 3 in the inner ring groove 202 can be collected by the inner wall of the inner ring groove 202, preventing the flame from swinging around, and more effectively concentrating the heat source generated by the flame to heat the air near the inner ring groove 202.

[0042] As shown in Figure 3 , the outer ring groove 203 is used to be clamped with the opening at the upper end of the furnace body 1. By clamping the outer ring groove 203 with the furnace body 1, the burner disc 2 can be quickly installed and removed, facilitating the subsequent maintenance and repair of the heater.

[0043] Further, the top surface of the outer ring groove 203 is higher than the inner ring groove 202, so that the inner ring groove 202 forms a sunken mounting space, which can effectively reduce the overall height of the heater and save space.

[0044] In the embodiment, the outer side surface of the mounting shell 201 extends upwardly from the inner ring groove 202, and the inclined direction is toward the center line direction of the burner disc 2. The extension to the top forms a circular top plate concentric with the inner ring groove 202.

[0045] As shown in Figure 4 and Figure 5As shown, the mounting shell 201 is provided with a heat insulation sleeve 9, the upper top plate of the heat insulation sleeve 9 is provided with a motor 7, during installation, the motor 7 is in the internal cavity of the mounting shell 201, the rotating shaft of the motor 7 extends upward and is connected with the fan blade 4, the fan blade 4 is driven to rotate by the motor 7. By arranging the motor 7 in the internal cavity of the mounting shell 201, the influence of the external environment on the working temperature of the motor 7 is effectively reduced. This helps to keep the motor 7 working at a lower temperature, reducing the performance decline or failure caused by high temperature.

[0046] Specifically, the middle part of the circular top plate at the top of the mounting shell 201 is provided with a mounting hole, after the motor 7 is installed on the upper top plate of the heat insulation sleeve 9, it passes through the mounting hole and is fixed in the internal cavity of the mounting shell 201. The outer side surface of the heat insulation sleeve 9 is parallel to the outer side surface of the mounting shell 201, a heat insulation cavity is formed between the outer side surface of the heat insulation sleeve 9 and the outer side surface of the mounting shell 201, which can further reduce the heat exchange between the internal cavity of the mounting shell 201 and the inner ring groove 202. The combination of the mounting shell 201 and the heat insulation sleeve 9 forms a double heat insulation barrier, so that the motor 7 operates in a good environment temperature.

[0047] As shown, Figure 4 The furnace body 1 is provided with a control module, which is used to control the running state of the whole warmer. The control module can control the on-off and output power of the whole warmer, making the whole warmer more intelligent and improving the user's experience.

[0048] Further, the outer wall of the furnace body 1 is provided with an operation panel 6 electrically connected with the control module. The operation panel 6 is provided with a motor button for controlling the opening and closing of the motor 7, and a power adjusting knob of the burner 3, which can start the warmer and adjust the operating power of the burner 3 by twisting the knob.

[0049] Working principle:

[0050] The gas source 8 in the furnace body 1 delivers gas to the burner 3 through the igniter 11, and the igniter 11 is connected with the gas source 8 through a delivery pipeline. The burner 3 ignites the gas to produce a bright flame. Since the burner 3 is arranged in the inner ring groove 202, the whole inner ring groove 202 is sunken into the interior of the furnace body 1, so the burner 3 arranged in the inner ring groove 202 is less affected by the external air, and can maintain a relatively stable heat source supply.

[0051] The motor 7 is installed in the mounting shell 201 protruding upward in the middle of the inner ring groove 202, which cooperates with the heat insulation sleeve 9 to effectively insulate the hot gas of the burner 3, so that the motor 7 can operate stably to drive the fan blade 4 to rotate and disturb. The heating cavity 13 surrounded by the mounting shell 201 and the mesh cover 5 arranged on the outer ring moves upward under the disturbance of the fan blade 4, is blocked by the top cover at the top of the fuselage 1, and then diffuses to the surrounding, and is discharged through the mesh cover 5, providing warmth for the user.

[0052] The basic principle, main features and advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited by the above embodiments, and various changes and improvements can be made to the present application without departing from the spirit and scope of the present application.
