[0026] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] Reference Figures 1 to 3According to the first embodiment of the utility model, a hidden air inlet heater comprises a housing 100, a combustion and heating device 200 and a shielding assembly 300. The housing 100 has a cavity 110. The combustion and heating device 200 is arranged in the housing 100 and is located in the cavity 110. The shielding assembly 300 is arranged in the housing 100. An air inlet slot 310 is formed between the shielding assembly 300 and the housing 100. The air inlet slot 310 is opened downward. The housing 100 has an air inlet portion 120 connected to the cavity 110. The air inlet portion 120 is located on the bottom wall side wall of the air inlet slot 310. By arranging the shielding assembly 300 near the air inlet portion 120 of the housing 100, the air inlet slot 310 opening downward can be formed. The air inlet portion 120 opened on the housing 100 can be hidden in the air inlet slot 310. On the one hand, the aesthetics can be improved. On the other hand, it is difficult for the user's fingers to bypass the air inlet slot 310 and extend into the cavity 110, which is safer.

[0028] Specifically, a gas heater generally uses gas to burn in a combustion and heating device 200 to generate heat, and a blower (not shown in the figure) can be provided to blow out the heat to achieve heating. The housing 100 has a cavity 110 for accommodating the combustion and heating device 200. The combustion and heating device 200 requires air supplement during combustion, so an air inlet 120 needs to be provided on the housing 100 for the combustion of the combustion and heating device 200. The shielding component 300 can be provided near the air inlet 120, and the shielding component can be installed on the housing 100. The split structure on the shell 100 forms an air inlet slot 310 with an opening facing downward between the shielding component 300 and the shell 100. The shape of the air inlet slot 310 is not limited, and the air inlet portion 120 can be set on the bottom wall of the air inlet slot 310. Therefore, when observed from the side, the air inlet portion 120 can be hidden in the shielding component 300, and the appearance is more simple and beautiful. At the same time, through the blocking of the shielding component 300, it is difficult for the user to bypass the air inlet slot 310 and extend his fingers into the cavity 110, which can also improve the safety of use.

[0029] It should be noted that the air inlet portion 120 is not limited to the above-mentioned embodiments, and other embodiments may also be adopted. For example, the air inlet portion 120 may also be arranged on the side wall of the air inlet slot 310, or the air inlet portion 120 may be arranged on both the side wall and the bottom wall of the air inlet slot 310.

[0030] Reference Figures 1 to 3In some embodiments of the present invention, the housing 100 includes a base 130 and a shell member 140. The shell member 140 is cylindrical and penetrates from top to bottom. The base 130 is installed at the bottom of the shell member 140. Specifically, the cylindrical shell member 140 has a simple appearance, and the vertically arranged cylinder is not easy to accumulate dust. The base 130 at the bottom of the shell member 140 is used to contact the ground and support the entire shell member 140 and the combustion and heating device 200. A cavity 110 can be formed between the base 130 and the shell member 140 for various components to be placed therein.

[0031] It is understandable that the outer shell 140 may also be in other shapes, which are not limited here.

[0032] Reference Figures 1 to 3 In some embodiments of the present invention, the bottom of the housing 140 has a bottom plate 141 extending inward horizontally, the top of the base 130 is connected to the bottom plate 141, the shielding assembly 300 includes a shielding plate 320, the shielding plate 320 extends downward from the bottom of the housing 140, and an air inlet slot 310 is formed between the shielding plate 320, the bottom plate 141 and the outer wall of the base 130, and the air inlet portion 120 includes at least one first air inlet 121, which is provided on the bottom plate 141 and located on the bottom wall of the air inlet slot 310. Through the above structure, the base 130 can be easily installed and the air inlet slot 310 with a downward opening can be easily formed.

[0033] Specifically, the bottom plate 141 can be annular without sealing the bottom of the outer shell 140. The base 130 can be connected to the bottom plate 141 by fasteners. The bottom plate 141 and the base 130 have a better supporting effect and are convenient for installing the base 130. At the same time, the material usage can be reduced and the cost can be saved. The baffle plate 320 can be arranged vertically downward at the bottom of the outer shell 140. The outer diameter of the base 130 is roughly smaller than the outer diameter of the baffle plate 320, so that there is a gap between the outer wall of the bottom shell and the baffle plate 320, so that the baffle plate 320, the bottom plate 141 and the base 130 form an air inlet slot 310 opening downward, which can hide the air inlet part 120 and is not easy to accumulate dust.

[0034] It should be noted that the bottom plate 141 is not limited to the above-mentioned embodiment, and other embodiments may also be adopted. For example, the bottom plate 141 may also be set as a whole plate.

[0035] Reference Figures 1 to 3In some embodiments of the present invention, the base 130 has a first receiving groove 131 open downward, the bottom wall of the first receiving groove 131 is provided with an air inlet 131A communicating with the cavity 110, the side wall of the first receiving groove 131 is provided with a second air inlet 131B, and the bottom height of the shielding plate 320 is less than or equal to the bottom of the second air inlet 131B. Through the cooperation between the second air inlet 131B and the shielding plate 320, the air intake can be further supplemented while hiding the second air inlet 131B.

[0036] Specifically, the base 130 can be injection molded to form a disc-shaped member with a first accommodating groove 131. The bottom of the base 130 is in contact with the ground or the desktop, making it difficult for air to enter. By arranging a second air inlet 131B on the side wall of the first accommodating groove 131, and opening an air inlet hole 131A on the bottom wall of the first accommodating groove 131, the second air inlet 131B is connected to the cavity 110, and the air intake volume can be supplemented to the cavity 110 through the second air inlet 131B, thereby further increasing the air intake volume. The second air inlet 131B is arranged opposite to the baffle plate 320. The second air inlet 131B can be arranged as a plurality of circular holes arranged at intervals, which are arranged around the side wall. The height of the lowest part of the second air inlet 131B is higher than or equal to the bottom end of the baffle plate 320. Therefore, the baffle plate 320 can block the second air inlet 131B. The baffle plate 320 can both provide protection and improve aesthetics.

[0037] Reference Figures 1 to 3 In some embodiments of the present invention, a ring plate 132 extending horizontally outward is provided at the bottom of the base 130 , and a side plate 133 extending downward is provided at the outer end of the ring plate 132 , and the side plate 133 is flush with the shielding plate 320 .

[0038] Specifically, the annular plate 132, the side plate 133 and the base 130 can be an integrated structure, and an inwardly recessed space is formed between the outer walls of the base 130, the annular plate 132 and the side plate 133 for air to enter, and the side plate 133 can be set flush with the baffle plate 320, making the appearance neater.

[0039] Reference Figures 1 to 3 In some embodiments of the present invention, the shielding plate 320 and the housing member 140 are an integrated structure. Specifically, the shielding plate 320 and the housing member 140 can be integrally injection molded, which is easy to process and has a better overall appearance.

[0040] Reference Figures 1 to 3 In some embodiments of the present invention, the combustion and heating device 200 includes a gas interface 210, and a first through hole 142 is provided on the side wall of the housing 140 for the gas interface 210 to pass through. The above structure can facilitate gas connection.

[0041] Specifically, the gas interface 210 is used to connect to an external gas supply pipeline. The combustion and heating device 200 can receive gas and air entering through the air intake part for combustion and heating, and the gas interface 210 can be penetrated to the outside through the first through hole 142 to facilitate gas communication.

[0042] Reference Figures 1 to 3 In some embodiments of the utility model, the side wall of the outer shell 140 is provided with a second accommodating groove 143 recessed inwardly, the bottom wall of the second accommodating groove 143 is provided with a first through hole 142, the bottom wall of the second accommodating groove 143 is provided with a third air inlet 144, and the outer shell 140 is provided with a detachable cover sheet 145, which can cover the opening of the second accommodating groove 143, and the cover sheet 145 has a second through hole 146 for air intake.

[0043] Specifically, a second accommodating groove 143 can be provided on the side wall of the outer shell 140, and the second accommodating groove 143 can form an accommodating space for the gas interface 210. At the same time, the second accommodating groove 143 can expand the surface area. By providing a third air inlet 144 on the bottom wall of the second accommodating groove 143, the air intake can be increased, and the third air inlet 144 can be provided as a plurality of circular holes spaced apart, which can further increase the air intake. The cover 145 can be provided flush with the outer shell 140 to block the second accommodating groove 143. It can be understood that the cover 145 also has a second through hole 146 for air to enter. After the air enters the second accommodating groove 143 from the second through hole 146, it enters the cavity 110 from the third air inlet 144. The cover 145 can roughly block the inwardly recessed second accommodating groove 143, reduce the dust accumulation in the second accommodating groove 143, and at the same time, improve the appearance of the appearance.

[0044] It should be noted that the location of the third air inlet 144 is not limited to the above-mentioned embodiment, and other embodiments may also be adopted. For example, the third air inlet 144 may also be arranged on the side wall of the second receiving groove 143, or the third air inlet 144 may also be arranged on the bottom wall and side wall of the second receiving groove 143, which can further increase the air intake volume.

[0045] Reference Figures 1 to 3 In some embodiments of the present invention, the cover sheet 145 is further provided with a first operating portion 147, and the first operating portion 147 is provided for a person to operate and disassemble. Specifically, the cover sheet 145 can be connected to the housing 140 by a snap-on connection, and the first operating portion 147 can be convenient for a user to hold and operate, so as to facilitate the disassembly of the cover sheet 145.

[0046] It is understandable that the cover piece 145 can also be connected to the outer shell 140 via fasteners.
