DETAILED DESCRIPTION

[0022] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0023] like Figure 1 , 2 As shown, an adjustable hot air nozzle structure for an oven includes an oven body 10, a closed door 11 is installed on the front of the oven body 10, a heat insulation board 12 is fixedly connected to the rear side of the oven body 10, a partition board 13 is fixedly connected to the upper and lower sides of the front of the heat insulation board 12, and a plurality of slots for hot air discharge are provided on the surface of the partition board 13. The outer sides of the two partition boards 13 are provided with reversible nozzles.

[0024] refer to Figure 2 , 3A heating device 20 is fixedly connected to the right side of the oven body 10 (the heating device 20 is mainly composed of a shell, a fan and a heating wire. When in use, the heating wire is heated by a power supply, and the fan is started. The fan draws air from the outside, and the air is heated when passing through the surface of the heating wire, thereby becoming hot air. The above is the prior art and will not be described in detail here). The input end of the heating device 20 is fixedly connected to an air inlet pipe 21, and the output end of the heating device 20 is fixedly connected to a connecting pipe 22. The left side of the connecting pipe 22 is fixedly connected to a shunt pipe 23. The upper and lower ends of the left side of the shunt pipe 23 are fixedly connected to a folded hose 24. The folded hose 24 passes through the surface of the heat insulation board 12, and the left side of the folded hose 24 is fixedly connected to a nozzle body 25.

[0025] When in use, the heating device 20 is started, and the heating device 20 draws in external air through the air inlet pipe 21 and heats the air. The heated air is then guided to the diversion pipe 23 through the connecting pipe 22 by the built-in fan, and is discharged to the two folded hoses 24 through the diversion of the diversion pipe 23, and finally ejected through the nozzle body 25. The ejected hot air passes through the surface of the partition plate 13 and blows to the object to be dried placed on the surface of the lower partition plate 13.

[0026] refer to Figure 2 , 3 4. A mirror-symmetrical connecting frame 30 is fixedly connected to the upper and lower sides of the interior of the oven body 10. A reversible rotating rod 31 is rotatably connected to the front and rear sides of the interior of the connecting frame 30. A reversing block 32 is fixedly connected to the rotating rod 31. The inner side of the reversing block 32 is fixedly connected to the nozzle body 25.

[0027] Specifically, the rotating rod 31 is fixedly connected to the gear 33; the top left side of the connecting frame 30 is fixedly connected to the connecting plate 34, the right side of the connecting plate 34 is fixedly connected to the first cylinder 35, the output end of the first cylinder 35 is fixedly connected to the tooth plate 36, and the tooth plate 36 is meshed with the surface of the gear 33. When in use, the first cylinder 35 is started by an external power supply, and the output end of the first cylinder 35 drives the tooth plate 36 to move rightward, and the cooperation of the tooth plate 36 and the gear 33 drives the rotating rod 31, the flip block 32 and the nozzle body 25 to flip counterclockwise. Similarly, when the output end of the first cylinder 35 drives the tooth plate 36 to move leftward, the cooperation of the tooth plate 36 and the gear 33 drives the nozzle body 25 to flip clockwise, thereby achieving the effect of the nozzle body 25 swinging left and right, and cooperating with the hot gas discharge of the nozzle body 25, thereby increasing the contact range of the hot gas, and then making objects at different positions on the partition plate 13 can contact with the hot gas.

[0028] refer to Figure 1 , 2The left side of the oven body 10 is fixedly connected with an exhaust pipe 40, which is used for gas exhaust. The left rear end of the oven body 10 is fixedly connected with a temperature sensor 41, which can feedback the real-time temperature inside the oven body 10. The left side of the oven body 10 is fixedly connected with a control device 60, which is electrically connected with the temperature sensor 41, the first cylinder 35, the second cylinder 54, and the heating device 20. When in use, the temperature sensor 41 feeds back the real-time temperature to the control device 60, and then the control device 60 starts the first cylinder 35, the second cylinder 54, and the heating device 20 through an external power supply.

[0029] In the above drying process, the outlet size of the nozzle body 25 cannot be adjusted according to the bottom surface width of the object to be dried. Therefore, when the bottom of the object to be dried is narrow, the nozzle body 25 has a larger opening, so that part of the hot air does not contact the surface of the object, thereby affecting the drying efficiency. Therefore, an adjustment mechanism is proposed.

[0030] refer to Figure 2 , 5 The regulating mechanism includes a pair of turning plates 53 fixedly connected to the front and rear sides of the nozzle body 25, the opposite sides of the two turning plates 53 are fixedly connected to the second cylinder 54, and the output end of the second cylinder 54 is fixedly connected to the cover plate 51.

[0031] Preferably, a pair of slide rails 50 are fixed on the left and right sides of the top of the nozzle body 25, and a pair of slide grooves 52 are respectively provided on the left and right sides of the bottom of the cover plate 51. The slide rails 50 are slidably connected with the corresponding slide grooves 52, so as to achieve a guiding effect when the cover plate 51 moves. When in use, the two second cylinders 54 are started by an external power supply, and the output end of the second cylinder 54 drives the cover plate 51 to slide, so that the cover plate 51 covers the output port of the nozzle body 25 according to the bottom width of the object to be dried.

[0032] The working principle of the utility model is as follows: the first cylinder 35 is started by the control device 60, and the output end of the first cylinder 35 drives the tooth plate 36 to move rightward, and the tooth plate 36 and the gear 33 cooperate to drive the rotating rod 31, the turning block 32 and the nozzle body 25 to turn counterclockwise. Similarly, when the output end of the first cylinder 35 drives the tooth plate 36 to move leftward, the tooth plate 36 and the gear 33 cooperate to drive the nozzle body 25 to turn clockwise, thereby achieving the effect of the nozzle body 25 swinging left and right, and cooperating with the hot air discharge of the nozzle body 25, thereby increasing the contact range of the hot air, and then making objects at different positions on the partition plate 13 can contact with the hot air.

[0033] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
