Specifically, the outer casing 1 has a box-like structural shape with a mounting chamber in the middle (the outer casing 1 of fig. 1 is cut away to show the internal condition, the inner casing 2 is cut away to show the internal condition), the structural shape of the inner casing 2 is a plate type, and the two walls of the outer casing 1 are connected such that the mounting chamber is divided into an inner layer and an outer layer, the outer layer is the ventilation chamber 101, and the inner layer is the heating chamber 201. The same side wall of the shell 1 is respectively provided with an air inlet 11 and an air outlet 12. The air inlet 11 is communicated with the ventilation cavity 101, and the air outlet 12 is communicated with the heating cavity 201. A through hole is provided on the inner case 2 at a position far from the air inlet 11 and the air outlet 12, and the fan 31 is connected to the through hole, and sucks air from the ventilation cavity 101 and blows air into the heating cavity 201. The combustion movement 32 is connected to the heating chamber 201 and is located at the center of the heating chamber 201, and electrical components such as a sensor and an ignition plug are arranged on the movement to cooperate with mechanical components so as to enable the heater to operate. The combustion movement 32 is installed in the inner case 2, so that wind energy blown into the heating cavity 201 by the fan 31 wraps the outer surface of the combustion movement 32, and further heat transferred out of the combustion movement 32 can be absorbed, and air is heated.

Further, the outer shell 1 and the inner shell 2 are of sheet metal structures, the air inlet 11 and the air outlet 12 are provided with a circle of mounting flanges, and the air inlet 11 and the air outlet 12 are connected with external air pipes by matching with the clamp.

Further, the housing 1 is also provided with a handle 13 and a control panel 14. The control panel 14 is electrically connected to the heating device 3, the power source 33, and other electronic devices.

Optionally, the inner shell 2 is also box-shaped, the outer shell 1 is sleeved outside the inner shell 2, the ventilation cavities 101 are spaced at intervals on the height, and a certain space is also spaced at two sides of the inner shell 1 and the inner shell 2, the space can be used for accommodating circuit structures of the heater (such as circuits of the control panel 14 and the heating device 3, the circuits are usually distributed on the wall to achieve a neat and attractive appearance, the spaces at two sides accommodate the circuits so that the ventilation effect of the ventilation cavities is better), and a sound absorbing structure can be arranged to absorb noise generated by vibration of the outer shell 1 and the inner shell 2, or elastic material filling is arranged to solve the vibration problem of the outer shell 1 and the inner shell 2.

Through this embodiment, when the heater works, the fan 31 operates to generate a pressure difference so that cold air enters the ventilation cavity 101 from the air inlet 11, and the cold air enters the heater under the driving of the fan 31, and after the combustion core 32 heats the cold air in the heating cavity 201, the hot air leaves the heater from the air outlet 12 and heats the environment. The noise generated by the heating means 3 propagates outwards and first hits the inner shell 2. The inner shell 2 absorbs part of the energy of the noise and reflects, the rest of the noise continues to propagate outwards and then hits the outer shell 1, and the outer shell 1 re-absorbs part of the noise, i.e. the noise repeatedly collides in the ventilation cavity 101. The two layers of shells absorb noise, so that the energy of the noise escaping from the outside is small, and the noise is small when being transmitted to the ears of a user, and the noise has no interference to the user.

Referring to fig. 1 to 4, an embodiment of the present invention is provided, wherein the ventilation cavity 101 extends horizontally, one end of the ventilation cavity 101 is connected to the air inlet 11, and one end of the ventilation cavity 101 away from the air inlet 11 is connected to the fan 31. The heater extends in the horizontal direction, one end of the heating cavity 201 is connected with the air outlet 12, and one end of the heater away from the air outlet 12 is communicated with the fan 31.

Specifically, the outer casing 1 has a top cover and a bottom plate arranged at intervals, the inner casing 2 is arranged between the top cover and the bottom plate, the ventilation cavity 101 is formed between the inner casing 2 and the top cover, the heating cavity 201 is formed between the inner casing 2 and the bottom cover, that is, a space spaced up and down is formed, and the fan 31 is connected to the inner casing 2 and communicates the ventilation cavity 101 with the heating cavity 201.

Optionally, the structure shape of the inner shell 2 is also a box shape, the bottom of the outer shell 1 is arranged, a state that the ventilation cavity 101 wraps the inner shell 2 is formed, and a gap between the two sides of the inner shell 2 and the outer shell 1 can accommodate not only noise but also elements or pipelines of the heater and other structures.

Through this embodiment, the ventilation cavity 101 is communicated between the fan 31 and the air inlet 11, so that noise generated by the fan 31 needs to be transmitted and can escape from the heater through the ventilation cavity 101. In this process, the energy of the noise is reduced, thereby reducing the interference of the noise to the user.

Referring to fig. 1 to 4, the present invention proposes an embodiment, where the ventilation cavity 101 includes a first ventilation cavity 101 and a second ventilation cavity 101 that are connected to each other, a channel of the first ventilation cavity 101 is smaller than that of the second ventilation cavity 101, the air inlet 11 is connected to the first ventilation cavity 101, and the fan 31 is disposed in the second ventilation cavity 101.

Specifically, the top case is provided with a bent shape such that one end of the top case is closer to the inner case 2 and the other end thereof is relatively farther from the inner case 2. So that the ventilation cavity 101 forms a first ventilation cavity 101 and a second ventilation cavity 101 with inconsistent passage areas, and the connection part between the first ventilation cavity 101 and the second ventilation cavity 101 is in a flaring shape. The air inlet 11 is communicated with the first ventilation cavity 101, and the fan 31 is arranged in the second ventilation cavity 101.

By this embodiment, the volume of the first ventilation cavity 101 is larger than that of the second ventilation cavity 101, and it can be understood that the fan 31 is in the second ventilation cavity 101, and the top casing is bent to enable the casing 1 to surround the fan 31, so that when the noise generated by the fan 31 propagates outwards, the energy of the noise is mainly absorbed by the casing 1, and only a small part of the energy escapes to the first ventilation cavity 101 and propagates out from the air inlet 11.

Referring to fig. 1 to 4, the present invention proposes an embodiment in which the inner housing 2 is provided with a sloping plate 21, the fan 31 is connected to one side of the sloping plate 21, and the combustion engine 32 is connected to the other side of the sloping plate 21, so that the fan 31 and the combustion engine 32 are not at the same level.

Specifically, the inner housing 2 has an inclined plate 21. The through hole is provided in the swash plate 21, and the fan 31 is connected to one side of the swash plate 21. The combustion engine 32 is connected to the other side of the swash plate 21. It will be appreciated that the blower 31 and the combustion movement 32 have a certain volume, and if the swash plate 21 is inclined and the blower 31 and the combustion movement 32 are connected to both sides of the swash plate 21, the blower 31 and the combustion movement 32 are offset in the vertical direction, and thus the size of the entire housing 1 in the horizontal direction is reduced.

Further, after the fan 31 is raised, the bottom can be used to accommodate the wiring of the control panel 14, making the overall heater more compact.

By this embodiment, the position of the blower 31 is raised by the inclined plate 21, thereby reducing the occupation space of the blower 31 and the combustion core 32 in the horizontal direction. As the heater is applied to the automobile cab and placed on the floor of the cab, the height space of the cab is redundant, but the floor space is less, and the floor space of the cab is reduced, so that the heater is more compact, the space of the cab is further avoided, the heater is easier, the heating device 3 with higher power is also facilitated, and the heating effect of the heater is improved. And the control shaft of the combustion fan 31 and the control shaft of the fan 31 in the combustion movement 32 are not identical, so that the rotation speeds of the combustion fan 31 and the fan 31 can be controlled respectively, and the control degree of freedom is improved.

Referring to fig. 1 to 4, an embodiment of the present invention is provided, where the fan 31 is provided with a suction inlet 311 and a blowing inlet 312, the suction inlet 311 is connected to the ventilation cavity 101, and the blowing inlet 312 is connected to the heating cavity 201. The air suction direction of the air suction inlet 311 is set at an angle to the extending direction of the ventilation cavity 101, and the air inlet direction of the air inlet 11 is set at an angle to the extending direction of the ventilation cavity 101.

Specifically, the two sides of the fan 31 are provided with air suction openings 311 for sucking air from the ventilation cavity 101. There is also a blowing port 312 for blowing air to the heater, and the air suction ports 311 are arranged on the top case in the vertical direction, i.e. open upwards, towards the cavity walls on both sides of the ventilation cavity 101. The fan 31 is internally provided with rotating blades.

Through this embodiment, when the fan blades of the fan 31 rotate, the noise emitted by the fan propagates to the two side walls of the ventilation cavity 101 along the air suction direction, and the two side walls absorb part of the energy of the noise. The rest of the noise continues to propagate along the extending direction of the ventilation cavity 101, and because the direction of the air inlet 11 is vertically arranged, the noise propagates to the ventilation cavity wall near the air inlet 11, and part of the noise energy is further absorbed by the cavity wall. So that the noise of the blower 31 is mainly absorbed by the inner case 2 and the outer case 1, not transmitted to the user's place.

In connection with fig. 1 to 4, an embodiment is proposed according to the invention, in which the cavity wall of the ventilation cavity 101 is covered with a sound-insulating material.

By this embodiment, the physical structure of the sound insulating material, such as porous, allows noise to propagate to the wall while being absorbed by the sound insulating material, further reducing noise propagation.

Referring to fig. 1 to 4, the heating device 3 further includes a power source 33, the power source 33 is disposed in the ventilation cavity 101 and located between the fan 31 and the air inlet 11, and the power source 33 is electrically connected to the combustion engine 32 and the fan 31.

Specifically, the power supply 33 is disposed outside the inner case 2, i.e., in the ventilation chamber 101, between the blower 31 and the air intake 11, so that air can pass through the power supply 33 when entering from the air intake 11 to reach the blower 31.

Specifically, the power supply 33 has a housing and an electronic component structure inside thereof. It will be appreciated that the power supply 33 has a cavity formed therein with varying configurations, and that when noise reaches the power supply 33, the energy of the noise will continuously oscillate within the cavity within the power supply, causing it to absorb a substantial portion of the noise energy so that the noise will not escape out of the heater.

Further, the power supply 33 is disposed at the junction of the first ventilation cavity and the second ventilation cavity, and cooperates with the top shell that is bent, so that the cavity shapes of the first ventilation cavity and the second ventilation cavity are rugged, the noise absorption area of the outer shell 1 or the inner shell 2 is increased, and the noise absorption capacity of the outer shell 1 and the inner shell 2 is increased.

Alternatively, the external structure of the power supply 33 can be provided with a plurality of fins to increase the heat dissipation effect. The heater can be arranged without a heat dissipation structure so as to reduce the volume, thereby reducing the volume and the weight of the whole heater and achieving the effect of compactness and portability.

Through the present embodiment, the power supply 33 supplies power to the heating device 3. The resistor can cause the power supply 33 to generate heat when providing electric energy, and the cold air entering from the air inlet 11 can effectively take away the heat of the power supply 33 under the continuous circulation of the fan 31, so that the temperature of the power supply 33 is reduced, and the temperature of the cold air can be improved to be blown out from the air outlet 12 later. And the position of the power supply 33 can also block the transmission of partial noise, thereby improving the noise reduction effect.

Referring to fig. 1 to 4, an embodiment of the present invention is provided, where the heating device 3 further includes a fan 31 controller, the fan 31 controller is disposed in the ventilation cavity 101 and adjacent to the air inlet 11, the fan 31 controller is provided with a heat dissipation structure, and the fan 31 controller is electrically connected to the fan 31.

Specifically, fins are provided on the outer surface of the fan 31 controller (not shown in the drawings) in a row, and a plurality of fins cause an increase in the surface area of the fan 31 controller. One end of the fin extends to the air inlet 11, and the other end is connected with a high temperature part of a fan 31 controller, usually a control chip and a heat pipe. So that the cold air also passes through the fins when entering from the air inlet 11.

Further, the fins are arranged in the vertical direction, so that the formed gap direction is communicated with the air inlet 11, air inlet is facilitated, noise transmission in the horizontal direction is blocked by the vertically arranged fins, and noise escape is further reduced.

Through this embodiment, the control chip in the fan 31 controller can generate heat during operation, and the cold wind that air intake 11 got into can effectually take away the heat of fan 31 controller under the continuous circulation of fan 31, reduces the heat of fan 31 controller, improves the control effect and the life-span of fan 31 controller.

Referring to fig. 1 to 4, the present invention proposes an embodiment, the heater further includes a silencing box 4, the silencing box 4 is connected to the housing 1, the silencing box 4 is provided with an air channel 41 and an exhaust channel 42, one end of the air channel 41 and one end of the exhaust channel 42 are both connected to the heating device 3, and the other end is both connected to an external space. Wherein the air passage 41 and the exhaust passage 42 are serpentine.

Specifically, the muffler box 4 includes an intake muffler box 4 and an exhaust muffler box 4, the intake muffler box 4 is provided with an air passage 41, and the exhaust muffler box 4 is provided with an exhaust passage 42. An air passage 41 connects the interior of combustion engine 32 to provide a combustion-supporting gas, typically oxygen in air. An exhaust passage 42 connects the interior of combustion engine core 32 to exhaust combusted exhaust gases.

Further, the air passage 41 and the exhaust passage 42 include a plurality of straight passages and a plurality of curved passages, which are combined in a serpentine structural shape. So that the surface areas of the channel walls of the air channel 41 and the exhaust gas channel 42 are increased.

With this embodiment, air enters combustion engine 32 through air passage 41 and exhaust exits combustion engine 32 through exhaust passage 42. Noise is generated during the process of sucking air from the outside and exhausting exhaust gas when the combustion movement 32 is combusted, and the air passage 41 and the exhaust gas passage 42 which are arranged in a meandering manner obstruct the noise transmission, so that the noise is reduced in energy step by step, and the noise is very small when transmitted to a user.

In connection with fig. 1 to 4, an embodiment is proposed in which the channel walls of the air channel 41 and the exhaust gas channel 42 are each covered with a sound-insulating material.

The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the description of the present invention and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the invention.
