Specific implementation

[0027] Specific embodiment one: please refer to Figures 1-5 A heating device of a blowing and air exchange integrated air duct, including base 1, end cover 2 and the fan 3, heating device 4 and control module 5 of detachable installation in base 1 inside respectively.

[0028] The fan 3 is located in the center inside base 1, and heating device 4 and control module 5 are located on the two sides of fan 3 respectively, and fan 3 and heating device 4 are electrically connected with control module 5 respectively, for controlling the operation of fan 3 and heating device 4.

[0029] The side wall of base 1 near heating device 4 is provided with air exchange opening 11, is used to fan 3 reverse rotation after from air exchange opening 11 output reaches the air exchange effect, and fan 3 positive rotation makes the airflow from heating device 4 output, reaches the effect of outputting cold wind or hot wind from heating device 4.

[0030] The base 1 is detachably installed with air duct 6 inside, and the two ends of air duct 6 are communicated with heating device 4 and air exchange opening 11 respectively, for making the airflow flow along the upper and lower parts of fan 3 and the pair of non-equal-width distribution channels formed by fan 3 and air duct 6 respectively, the channel length of air exchange opening 11 area is lengthened, the flow utilization rate is improved, and the heating and air exchange efficiency is higher.

[0031] Specifically, as shown in Figure 2 The surface of end cover 2 is provided with fan air inlet 21 and hot air outlet 22, and the positions are respectively corresponding with fan 3 and heating device 4, for separating the air inlet and exhaust path, avoiding heat loss, and improving the heating effect of the heating device.

[0032] Specifically, as shown in Figure 3The air duct 6 shown includes a circumferential plate 61 and a partition plate 62. One end of the circumferential plate 61 abuts against one side of the heating device 4 close to the upper side wall of the base 1, and the other end abuts against the middle of the lower side wall of the base 1, forming a closed space wrapping around the circumference of the fan 3. The upper part of the partition plate 62 forms a flow channel for the heating air flow with the one end of the circumferential plate 61 abutting against the heating device 4, and the lower part of the partition plate 62 forms an air exchange channel for the air exchange air flow with the lower side wall of the base 1. The flow channel for the heating air flow and the air exchange channel are independent of each other, avoiding the escape of hot air from the air exchange channel.

[0033] Specifically, as shown in the drawings, Figure 4 The heating device 4 shown includes, from bottom to top, an air guide base 41, a support frame 42, a PTC heating element 43, and a dust collection module 44. The air guide base 41 is detachably installed inside the base 1 and is arranged in an arc shape from low to high along the direction of the air flow blowing into the heating device 4, for guiding the air flow to pass through the PTC heating element 43 stably. The support frame 42 is detachably installed on the top of the air guide base 41, for supporting the PTC heating element 43. The PTC heating element 43 is embedded inside the support frame 42, and the dust collection module 44 is fitted outside the support frame 42. The top of the dust collection module 44 is a tapered opening. When the hot air passes through the tapered opening, the speed of the hot air will be accelerated, which improves the efficiency of the hot air while reducing the outlet pressure through air flow acceleration, thereby sucking the hot air inside the heating device 4 out, achieving the effect of further improving the heating efficiency. A filter grid is arranged inside the tapered opening, for blocking foreign matter from entering the inside of the base 1 from the heating device 4, ensuring the inside to be clean and prolonging the service life of the equipment.

[0034] Specifically, the profile of the partition plate 62 is an acute triangle formed by a slanted plate 621, an arc plate 622, and a straight plate 623 connected head to tail. The slanted plate 621 is arranged in parallel with the side of the circumferential plate 61 close to the air guide base 41, for forming the flow channel for the heating air flow. The straight plate 623 is arranged in parallel with the lower side wall of the base 1, for forming the air exchange channel for the air exchange air flow. The arc plate 622 is arranged in a ring shape around the fan 3, for making the air flow between the arc plate 622 and the fan 3 flow uniformly, avoiding vortex between the arc plate 622 and the fan 3, which causes the air flow to collide with the arc plate 622 and generate a large noise.

[0035] Specifically, the two ends of the arc plate 622 are connected to the slanted plate 621 and the straight plate 623 respectively through arc-shaped smooth transitions, for reducing the collision resistance of the air flow with the partition plate 62 and improving the smoothness of the air flow.

[0036] Specifically, a plurality of support rib plates 63 are arranged between the side of the circumferential plate 61 close to the heating device 4 and the upper side wall of the base 1. The support rib plates 63 are fixedly connected with the circumferential plate 61, for enhancing the structural stability of the circumferential plate 61, avoiding displacement of the circumferential plate 61 after being impacted by the air flow, and affecting the heating and air exchange efficiency.

[0037] Specifically, the top of the support rib 63 has a wire groove 631 for the wires connecting the control module 5 and the heating device 4 to pass through, which avoids wire tangling and friction and improves the service life of the accessories.

[0038] Specifically, a wire groove 64 is provided on the bottom side of the circumferential plate 61 away from the heating device 4, for the wires connecting the control module 4 and the fan 3 to pass through, thereby improving the safety of the components by optimizing the wire arrangement.

[0039] Specifically, such as Figure 5 The air exchange port 11 shown is provided with an air guide structure 111 on the inner side. The air guide structure 111 is detachably installed between the lower side wall of the base 1 and the straight plate 623. The air guide structure 111 forms a gradually narrowing channel through the arc guide from top to bottom, which is used to guide the airflow entering the air exchange port 11 along the air duct 6 to achieve the effect of stable air exchange.

[0040] During use, the heater is installed in the work area. Users can turn on the heating device 4 and the fan 3 in either forward or reverse rotation according to their needs by adjusting the control module 5. When heating is needed, the heating device 4 is turned on and the fan 3 is set to forward rotation. The fan 3 draws in airflow from the fan inlet 21. The airflow flows along the channel between the circumferential plate 61 and the inclined plate 621 to the air guide base 41, and is guided by an arc to the PTC heating element 43 above. The airflow through the PTC heating element 43 passes through the air collection and dust prevention module 44 to accelerate the hot air out, achieving the effect of outputting hot air. If there is no need for hot air and only airflow is required, the heating device 4 can be turned off. If ventilation is needed, the fan 3 is set to reverse rotation. The airflow is discharged along the ventilation channel between the straight plate 623 and the lower side wall of the base 1 to the air guide structure 111. The airflow is guided by an arc to form a gradually narrowing channel to guide the airflow to the ventilation port 11, achieving stable and low-noise exchange of indoor and outdoor air.
