Description

A device for preventing direct airflow from an oven outlet Technical Field

[0001] This utility model relates to the field of oven technology, specifically to an oven anti-direct-blowing air outlet device. Background Technology

[0002] An oven is a device used for heating, drying, sterilization, etc. It is widely used in scientific research, industry, medical fields and other fields. After the fabric is cleaned, it needs to be placed in an oven for drying.

[0003] However, most fabric drying ovens currently in use have nozzles that blow air directly outwards, which is not conducive to circulating airflow and can easily lead to uneven drying of the fabric. At the same time, direct airflow can cause some areas of the fabric to be heated excessively, which can easily cause damage. To address these issues, we propose a device to prevent direct airflow from the drying oven's nozzles. Summary of the Invention

[0004] The purpose of this invention is to provide a device for preventing direct airflow from an oven outlet, in order to solve the problems mentioned in the background art.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example

[0021] Please refer to Figures 1-5. This utility model provides a technical solution: a device for preventing direct airflow from an oven, comprising a housing 1. Two round rods 2 are rotatably connected to the inner walls of both sides of the housing 1. A common round tube 3 is fixedly connected between the ends of two round rods 2 that are close to each other. Multiple inclined nozzles 4 are connected and fixed to the bottom of the round tube 3. The right end of one of the round rods 2 on the right extends outside the housing 1. A gear 5 is fixedly sleeved on the outer side of the right round rod 2. A rack 6 meshes with the bottom of the gear 5. A connecting block 7 is fixedly connected to the rear side of the rack 6. A ball bearing 8 is embedded in the rear side of the connecting block 7. A hot air blower 9 is fixedly connected to the top of the housing 1. A flexible hose 10 is connected and fixed to the outlet of the hot air blower 9. The bottom end of the flexible hose 10 is connected and fixed to the top of the round tube 3. Fixing blocks 11 are fixedly connected to the inner walls of both sides of the housing 1. An electric telescopic rod 12 is fixedly connected to the top of the fixed block 11. A pressure plate 13 is fixedly connected to the end of the output shaft of the electric telescopic rod 12. The fabric is placed on top of the two fixed plates 14. The electric telescopic rod 12 is started to drive the pressure plate 13 to move downward and fix the fabric. The hot air blower 9 is started to generate hot air, which is discharged into the hose 10 through the air outlet. The hose 10 discharges the hot air into the round pipe 3. The round pipe 3 sprays the hot air out through the nozzle 4 to dry the fabric. The motor 15 is started. The motor 15 works continuously and can drive the nozzle 4 to swing back and forth in a cycle, so as to dry the fabric evenly. The air outlet of the nozzle 4 is not in a direct blowing state, which facilitates the cyclic swinging for blowing operation, avoiding the phenomenon of uneven drying of the fabric and avoiding the phenomenon of excessive heating in some areas of the fabric, which may cause damage.

[0022] In this embodiment, specifically: fixing plates 14 are fixedly connected to both inner walls of the box 1, and a motor 15 is fixedly connected to the rear side of the box 1.

[0023] In this embodiment, specifically: an eccentric wheel 16 is fixedly connected to the end of the output shaft of the motor 15, and the outer side of the eccentric wheel 16 is in rolling contact with the ball 8;

[0024] In this embodiment, specifically: an L-shaped plate 17 is fixedly connected to the right side of the box 1, and the right end of a round rod 2 on the right side is rotatably connected to the inner wall of the right side of the L-shaped plate 17.

[0025] In this embodiment, specifically: two support blocks 18 are fixedly connected to the bottom inner wall of the L-shaped plate 17, and the same positioning rod 19 is fixedly connected between the two support blocks 18; a rectangular block 20 is fixedly connected to the bottom of the rack 6.

[0026] In this embodiment, specifically: the rectangular block 20 is slidably sleeved on the outside of the corresponding positioning rod 19, and the rectangular block 20 and the corresponding support block 18 are fixedly connected by the same spring 21;

[0027] In this embodiment, specifically: the spring 21 is movably sleeved on the outside of the corresponding positioning rod 19, the front side of the box 1 is rotatably connected to two door panels 22, and multiple ventilation holes 23 are opened on the top inner wall of the box 1.

[0028] In operation, this invention works as follows: When drying fabric, the fabric is placed on top of the two fixed plates 14. Then, the electric telescopic rod 12 is activated, causing the pressure plate 13 to move downwards and fix the fabric. Next, the hot air blower 9 is activated, generating hot air which is discharged through the air outlet into the flexible hose 10. The flexible hose 10 then discharges the hot air into the circular pipe 3, which sprays the hot air through the nozzle 4 to dry the fabric. Then, the motor 15 is activated, causing the eccentric wheel 16 to rotate. The eccentric wheel 16 rotates the first half turn, squeezing the ball bearing 8. Under this squeezing force, the ball bearing 8 moves the connecting block 7 forward. The connecting block 7 moves the rack 6, which in turn moves the rectangular block 20. The rectangular block 20 slides outside the positioning rod 19. During its movement, the rectangular block 20 compresses the spring 21. The movement of the rack 6... The rotating gear 5 drives the rotating rod 2, which in turn drives the rotating tube 3. The rotating tube 3 then drives the nozzle 4 to swing forward. After the eccentric wheel 16 rotates half a turn, it releases the pressure on the ball bearing 8. At this time, the spring 21, which was under compression, returns to its original position. The elastic force of the spring 21 drives the rectangular block 20 to move. The rectangular block 20 drives the rack 6 to move backward. The movement of the rack 6 drives the rotating gear 5, which in turn drives the rotating rod 2. The rotating rod 2 drives the rotating tube 3, which in turn drives the nozzle 4 to swing backward. The motor 15 continues to work, which can drive the nozzle 4 to swing back and forth in a cycle, thereby enabling uniform drying of the fabric. This constitutes a direct-blowing air outlet device for the drying oven, preventing the air outlet of the nozzle 4 from blowing directly into the fabric. This facilitates the cyclic swinging airflow and avoids uneven drying of the fabric, preventing damage caused by excessive heating in certain areas of the fabric.
