Because the first connecting arm 212 and the second connecting arm 222 are smaller in size in the width direction of the inner face mask, the rib at the edge of the inner face mask and the rib at the edge of the first air outlet 201 are directly used as the reinforcing rib 202, so that the structural strength and flexibility of the first connecting arm 212 and the second connecting arm 222 are improved.
In order to enable the first connecting arm 212 and the second connecting arm 222 to be capable of limiting mutually in the width direction of the inner layer mask to stabilize the structure of the first air outlet 201, one of the first connecting arm 212 and the second connecting arm 222 can be provided with the inserting rib 203, the other one is provided with the inserting groove 204, the inserting rib 203 is in butt joint with the inserting groove 204, so that the first connecting arm 212 and the second connecting arm 222 are mutually supported and limited in the width direction of the inner layer mask, deformation of the shape of the first air outlet 201 after the first part 21 and the second part 22 are fixed with the box body 1 can be avoided, and the annular air outlet structure is ensured to meet the design requirements.
The first connecting arm 212 and the second connecting arm 222 are respectively and fixedly connected with the outer mask 3, so that the structural stability of the connection between the first connecting arm 212 and the second connecting arm 222 can be improved. The specific fixed connection manner may adopt a structure with a small occupied space, for example, a buckle structure adopted in this embodiment, specifically, a first buckle 214 connected with the outer-layer mask 3 is arranged on the first connection arm 212, and a second buckle 224 connected with the outer-layer mask 3 is arranged on the second connection arm 222.
In the present embodiment, a reinforcing plate 23 for increasing the structural stability after the connection of the first connection arm 212 and the second connection arm 222 may be connected between the first portion 21 and the second portion 22. The reinforcing plate 23 can be connected to the first connecting arm 212 and the second connecting arm 222 by screws, so that the assembly is convenient, and the reinforcing plate can be as close to the connection position of the first connecting arm 212 and the second connecting arm 222 as possible. The reinforcing plate 23 may be made of plastic or metal having high strength. Only one reinforcing plate 23 is illustrated, and in an actual product, whether to install the reinforcing plate 23 between the two first connecting arms 212 and the second connecting arm 222 can be determined according to actual needs.
For further improving the structural stability after first linking arm 212 and second linking arm 222 are connected, can be equipped with first spacing muscle 215 at first linking arm 212, outer face guard 3 is equipped with first spacing groove 302, and first spacing muscle 215 inserts first spacing groove 302 cooperation, and second linking arm 222 is equipped with second spacing muscle 225, and outer face guard 3 is equipped with second spacing groove 303, and second spacing muscle 225 inserts the cooperation of second spacing groove 303. The first restraint groove 302 and the second restraint groove 303 may be connected into one groove. It is understood that, in some cases, only the first limiting rib 215 and the first limiting groove 302 may be provided, or only the second limiting rib 225 and the second limiting groove 303 may be provided, for example, the position of the reinforcing plate 23 may not be provided with the limiting rib and the limiting groove.
In order to reduce the cost of the mold, the first portion 21 and the second portion 22 may be designed to be of a central symmetrical structure, and may be symmetrical about the center of the first air outlet 201. Thus, only one mold needs to be designed to produce the first part 21 and the second part 22. Therefore, one of the two first connecting arms 212 is required to be provided with the insertion groove 204, the other one is provided with the insertion rib 203, and the second connecting arm 222 is designed correspondingly.
In order to better cooperate the annular air outlet structure, the heating assembly in this embodiment includes annular heater 4, and for the product is more pleasing to the eye, the heating assembly still includes the dress trim cover 41 that covers annular heater 4, forms annular air outlet between dress trim cover 41's the edge and the edge of second exhaust vent 301, and annular heater 4 can be close to annular air outlet more, and warm braw efficiency and effect can be better.
The product of the invention can be a warm air bath heater arranged on a ceiling, and can also be heating equipment such as a floor warm fan and the like.
