Detailed Description

The present invention is described in detail below with reference to the attached drawings:

as shown in fig. 1, 2, 3, and 4, an outdoor chair with a heating function includes a base 1 made of glass fiber reinforced plastic and a horizontal sitting surface 2 for people to sit on, which is located on the top of the base 1, the chair in this embodiment is a high-leg chair, in which the legs supported on the ground are made of glass fiber reinforced plastic and are separately inserted into the base 1, so as to facilitate installation of devices inside the base 1, routing of wires, and the like. The base 1 is provided with an upper cavity 31, a middle cavity 32 and a lower cavity 33 (wherein the lower cavity 33 is formed by enclosing the legs and the base 1) which are sequentially connected below the seat 2, and a plurality of first through holes 11 penetrating to the outside of the base 1 are formed between the upper cavity 31 and the seat 2. Heating devices 4 composed of common heating resistance sheets, resistance wires and the like are arranged in the middle cavity 32 and the lower cavity 33, the heating devices 4 run through external power supply, the circuits of the heating devices are connected to the outside (not shown in the figure) through holes preset in the bottom of the base 1 and the support legs, the heating devices 4 in the embodiment are also provided with temperature sensors, and therefore the overheating can be avoided through the modes of detecting the circuit breaking/reducing the heating power after reaching a certain temperature, on one hand, the energy is saved, and on the other hand, the influence of overheating on the thermal deformation of the base 1 is reduced. A plurality of second through holes 12 penetrating to the outside of the base 1 are arranged between the lower cavity 33 and the surface of the base 1, and the second through holes 12 are in a structure inclined from outside to inside. When the air heating device operates, the heating device 4 operates to heat air in each cavity, the heated air automatically forms a chimney effect in the cavity, so that the hot air automatically moves upwards into the upper cavity 31 and is finally sent out from the first through hole 11 to heat a human body sitting on the seat surface 2, the air pressure in the lower cavity 33 is reduced after the hot air moves upwards, and external air is sucked inwards from the second through hole 12 which inclines inwards upwards for supplement. The heating device in the middle cavity 32 is mainly used for auxiliary heating and heat preservation effects in the upward hot air process.

In this embodiment, the cavity structures of the lower cavity 33 and the middle cavity 32 are in a truncated cone shape, and the horizontal cross-sectional areas of the lower cavity and the middle cavity are gradually reduced from bottom to top, so that the flow speed can be increased by the reduced flow cross-sectional area in the rising process of the hot air, and the heat supply capacity is improved. The upper cavity 31 in this embodiment is a flat cylindrical structure and gradually enlarges at the transition with the middle cavity 32, so that the hot air can be uniformly diffused into a larger area after entering the upper cavity, thereby realizing heating of a user in a larger range.

In this embodiment, the heating device 4 is provided with a heat insulation layer 15 made of asbestos and adhered to the heating device 4 between the positions corresponding to the inner walls of the middle cavity 32 and the lower cavity 33, so as to isolate direct heating of the structure of the base 1, thereby avoiding deformation and damage caused by local overheating.

In this embodiment, the surfaces of the middle cavity 32 and the lower cavity 33 are covered with the insulating layer 16 made of aluminum foil foam to efficiently heat the internal air with the high reflectivity of the aluminum foil, and the thermal influence on the base 1 is further reduced, and the insulating layer 15 is also mounted on the insulating layer 16 in a sticking manner.

Referring to fig. 3, in the present embodiment, a third through hole 13 is formed in the base and penetrates through the upper cavity 31, and an axis of the third through hole 13 is inclined downward from the upper cavity 31 by an angle of 45 ° to 60 °, so that part of the hot air can escape from the third through hole 13 to provide hot air directed downward toward the leg, thereby achieving a wider temperature supplying and heating effect for the human body.

Referring to fig. 4, in the present embodiment, a backrest extending upward from the edge of the seat surface 2 is integrally disposed on the base 1, the backrest is connected to the upper cavity 31 and a fourth through hole 14 outside the base 1, the fourth through hole 14 is disposed in a vertical direction from bottom to top or is inclined toward the seat surface 2, and in the present embodiment, the fourth through hole 14 is inclined toward the seat surface 2 to provide a larger area of heat directly delivered to the back of the human body.

Referring to fig. 3 and 4, in the present embodiment, the third through hole 13 and the fourth through hole 14 are both cylindrical holes, and the fans 5 whose air supply directions point to the outside of the base 1 are detachably installed inside the cylindrical holes through a threaded structure, so that the active air supply effect of the fans 5 is used to enhance the air supply and heat supply effects to the legs and the back of the human body, so as to prevent the hot air from losing upward after leaving the third through hole 13 and the fourth through hole 14 and not playing a heat supply effect in the external space. In the embodiment, the fan 5 is a fan structure in which, for example, fan blades connected by a small motor are mounted on a common cylindrical housing having an outer periphery in threaded connection with the third and fourth through holes by a grid-shaped bracket, and for safety, mesh sheets are provided at both ends of the housing to prevent foreign matter, clothing, and a human body from contacting the fan blades. The installation mode can also be selected as the mode of convenient dismouting such as elasticity joint, tip pass through buckle connection in other preferred embodiments. The battery is installed to this shell inboard and is the power supply of fan 5 to can conveniently select fan 5's quantity to improve the utilization efficiency according to ambient temperature at that time, make fan 5's dismouting, use more convenient simultaneously, the battery can be rechargeable battery or disposable battery, the practicality of being convenient for.

Referring to fig. 2, in the embodiment, the base 1 is provided with the structure grooves 17 extending in the vertical direction and arranged in parallel along the circumferential direction of the inner walls of the lower cavity 33, the middle cavity 32 and the upper cavity 31, and the structure grooves 17 can accommodate the thermal deformation of the inner walls caused by the heat transferred from the heating device 4 to the base 1, thereby reducing the damage of the inner wall structure caused by the mutual interaction such as cracking and the like due to heat, which affects the strength and the service life.

In this embodiment, the seat cushion 6 that the removable porous sponge, porous latex etc. of being equipped with in seat 2 top were made to make the hot-air of seeing off from first through-hole 11 further disperse through the hole of seat cushion 6, provide more comfortable, be difficult for by the air current of human buttock perception, improve the travelling comfort.

The above embodiments are only described for the preferred embodiments of the present invention, and are not intended to limit the concept and scope of the present invention, and the various modifications and improvements made by the ordinary person in the art without departing from the design concept of the present invention all fall into the protection scope of the present invention.
