Description

Technical Field

[0001] This utility model relates to the field of heater technology, specifically a heater with a built-in window closure structure. Background Technology

[0002] During the cold winter, heaters have become an indispensable heating device in people's lives, providing a warm indoor environment. However, traditional heaters have some problems during use, which limit their performance and lifespan.

[0003] Traditional heaters typically use electric heating elements to heat the air, which is then blown into the room by a fan. However, the air vents of these heaters are mostly kept open, even when the heater is not running. This allows dust to easily enter the heater and accumulate on the heating elements and fan. Dust buildup not only affects the heater's heating efficiency but also increases energy consumption and reduces its lifespan. Furthermore, dust entering the heater can also pose safety hazards. Utility Model Content

[0004] The purpose of this invention is to provide a heater with a built-in window closure structure to solve the problems mentioned in the background art.

[0007] A sealing component is provided inside the air outlet, and the sealing component is used to seal the air outlet;

[0008] The outer casing is provided with a blower assembly, which can blow air heated by the electric heating grid from the air outlet to the outside of the outer casing. The electric heating grid is located between the blower assembly and the sealing assembly.

[0009] The housing is provided with a drive component, which cooperates with the blowing component and the sealing component respectively. When the drive component is running, the blowing component will follow, and at the same time, the drive component will use centrifugal force to drive the sealing component to switch the air outlet from a sealed state to an open state.

[0011] The sealing assembly includes multiple sealing plates, which are stacked sequentially and rotatably disposed within the air outlet.

[0012] Each pair of adjacent sealing plates is rotatably connected by connecting pieces. One of the sealing plates is provided with a U-shaped block. When the U-shaped block pushes the sealing plate to rotate, the other sealing plates will rotate along with it under the influence of the connecting pieces.

[0013] The heater with a built-in window closure structure as described above:

[0014] The blower assembly includes a protective cover and a rotating shaft, the rotating shaft being rotatably mounted on the protective cover;

[0015] The protective cover is mounted on the outer casing and corresponds to the electric heating mesh installed inside the air outlet.

[0016] The heater with a built-in window closure structure as described above:

[0017] An impeller is coaxially mounted on the rotating shaft, and a first bevel gear is coaxially mounted on one end of the rotating shaft.

[0018] The heater with a built-in window closure structure as described above:

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0036] Please see Figure 1-5As an embodiment of this utility model, a heater with a built-in window closure structure includes a shell 1 and an electric heating mesh 2. The front end of the shell 1 is provided with an air outlet 101, and the electric heating mesh 2 is disposed in the air outlet 101 for heating air.

[0037] A sealing component is provided inside the air outlet 101, which is used to seal the air outlet 101;

[0038] A blower assembly is provided on the outer casing 1. The blower assembly can blow air heated by the electric heating mesh 2 from the air outlet 101 to the outside of the outer casing 1. The electric heating mesh 2 is located between the blower assembly and the sealing assembly.

[0039] The housing 1 is provided with a drive assembly, which cooperates with the blowing assembly and the sealing assembly respectively. When the drive assembly is running, the blowing assembly will follow, and at the same time, the drive assembly will use centrifugal force to drive the sealing assembly to switch the air outlet 101 from the sealed state to the open state. When the drive assembly stops running, the blowing assembly stops, and the sealing assembly resets to close the air outlet 101 again.

[0040] In this embodiment, when the heater is started, the drive component starts to operate, and the drive component drives the blower component to start working. The blower component generates airflow, which blows the air heated by the electric heating grid 2 toward the air outlet 101. At the same time, the drive component uses centrifugal force to drive the sealing component to move, so that the sealing component moves away from the sealed position of the air outlet 101, and the air outlet 101 switches from the sealed state to the open state. The heated air is blown to the outside of the heater through the air outlet 101.

[0041] During the operation of the heater, the blower assembly works continuously, blowing the air heated by the electric heating net 2 out of the heater to provide heat to the room. The electric heating net 2 is located between the blower assembly and the sealing assembly, ensuring that the air is heated by the electric heating net 2 before being blown out by the blower assembly. The sealing assembly is kept in the open position under the action of centrifugal force, ensuring that the air outlet 101 is unobstructed and that the air can be discharged smoothly.

[0042] When the heater stops running, the drive component stops working, the blower component stops and stops generating airflow, the sealing component loses the centrifugal force and begins to reset, resealing the air outlet 101; when the heater stops running completely, the air outlet 101 is sealed again by the sealing component to prevent dust from entering the machine body.

[0043] As a further embodiment of this utility model, the sealing assembly includes a plurality of sealing plates 3, which are stacked sequentially and rotatably disposed within the air outlet 101.

[0044] Each of the two adjacent sealing plates 3 is rotatably connected by a connecting piece 4. One of the sealing plates 3 is provided with a U-shaped block 5. When the U-shaped block 5 pushes the sealing plate 3 to rotate, the other sealing plates 3 will rotate along with it under the drive of the connecting pieces 4.

[0045] In this embodiment, when the heater is turned on, the drive component starts to run and pushes the U-shaped block 5. After the U-shaped block 5 is pushed, it drives the sealing plate 3 fixedly connected to it to start rotating. Since the adjacent sealing plates 3 are rotatably connected by the connecting piece 4, when one sealing plate 3 rotates, it will drive the adjacent sealing plates 3 to rotate together through the connecting piece 4.

[0046] Multiple sealing plates 3 rotate sequentially under the drive of connecting piece 4, eventually causing the entire sealing assembly to switch from the closed position to the open position, the air outlet 101 is opened, and the heated air can be blown to the outside of the heater through the air outlet 101.

[0047] During the operation of the heater, the sealing component remains in the open position, the air outlet 101 is unobstructed, and the heated air can be discharged smoothly. Under the connection of the connecting piece 4, the sealing plate 3 remains in a stable open state to ensure air circulation.

[0048] When the heater stops running, the drive component stops working, the U-shaped block 5 is no longer pushed, the sealing plate 3 loses external force and returns to the initial closed position, re-closing the air outlet 101.

[0049] As a further embodiment of this utility model, the blower assembly includes a protective cover 6 and a rotating shaft 7, wherein the rotating shaft 7 is rotatably mounted on the protective cover 6.

[0050] The protective cover 6 is disposed on the outer shell 1 and corresponds to the electric heating mesh 2 disposed inside the air outlet 101;

[0051] An impeller 8 is coaxially mounted on the rotating shaft 7, and a first bevel gear 9 is coaxially mounted on one end of the rotating shaft 7.

[0052] In this embodiment, when the heater is started, the drive assembly starts to run. The drive assembly drives the first bevel gear 9 to start rotating through mechanical transmission. The rotation of the first bevel gear 9 is transmitted to the impeller 8 through the rotating shaft 7, causing the impeller 8 to start rotating. The rotation of the impeller 8 generates airflow, which blows the air heated by the electric heating grid 2 from the air outlet 101 to the outside of the heater.

[0053] During the operation of the heater, the first bevel gear 9 rotates continuously, which drives the impeller 8 to rotate continuously through the rotating shaft 7. The rotation of the impeller 8 generates a continuous airflow, which blows the air heated by the electric heating grid 2 towards the air outlet 101 to provide heat to the room.

[0054] As a further embodiment of this utility model, the drive assembly includes a rotating rod 10 and a motor 11, wherein the rotating rod 10 is rotatably mounted on the outer casing 1;

[0055] The motor 11 is mounted on the housing 1. The output end of the motor 11 is coaxially and fixedly connected to one end of the rotating rod 10. The other end of the rotating rod 10 is coaxially provided with a second bevel gear 12 that meshes with the first bevel gear 9.

[0056] A retaining ring 13 and a disc 14 are coaxially arranged on the rotating rod 10. The disc 14 is close to the motor 11. A slide block 15 is slidably arranged on the rotating rod 10 between the retaining ring 13 and the disc 14.

[0057] A spring 16 is sleeved on the outer wall of the rotating rod 10. The two ends of the spring 16 abut against the retaining ring 13 and the slide block 15 respectively, and the spring 16 is in a compressed state.

[0058] A rotating seat 17 is rotatably mounted on the slide block 15. A plurality of sliding grooves 18 are provided on the disk 14 along its length direction. A counterweight slider 19 is slidably mounted in each of the plurality of sliding grooves 18. The plurality of counterweight sliders 19 are located near the center of the disk 14 under the action of the spring 16.

[0059] The multiple counterweight sliders 19 and the rotating base 17 are rotatably connected by multiple connecting rods 20. An L-shaped rod 21 is provided on the sliding base 15, and the end of the L-shaped rod 21 is fixedly connected to the U-shaped block 5.

[0060] In this embodiment, when the heater is started, the motor 11 starts running. The output end of the motor 11 drives the rotating rod 10 to rotate. The rotation of the rotating rod 10 is transmitted to the first bevel gear 9 through the second bevel gear 12. The rotation of the first bevel gear 9 drives the rotating shaft 7 to rotate, which in turn drives the impeller 8 to rotate, thus generating airflow.

[0061] As the rotating rod 10 rotates, the counterweight slider 19 on the disc 14 begins to slide outward under the action of centrifugal force. The outward sliding of the counterweight slider 19 drives the rotating seat 17 to move towards the retaining ring 13 through the connecting rod 20. The movement of the rotating seat 17 drives the slide seat 15 to slide along the rotating rod 10 towards the retaining ring 13. The sliding of the slide seat 15 further compresses the spring 16.

[0062] The sliding of the slide block 15 drives the U-shaped block 5 to move towards the retaining ring 13 via the L-shaped rod 21. The movement of the U-shaped block 5 pushes the sealing plate 3 to start rotating. Since the sealing plates 3 are connected by the connecting piece 4, the rotation of one sealing plate 3 will drive the other sealing plates 3 to rotate in sequence, eventually causing the entire sealing assembly to switch from the closed position to the open position. The air outlet 101 is opened, and the heated air can be blown to the outside of the heater through the air outlet 101.

[0063] During the operation of the heater, the motor 11 runs continuously, driving the rotating rod 10 to rotate. The meshing transmission of the second bevel gear 12 and the first bevel gear 9 causes the impeller 8 to rotate continuously, generating a continuous airflow. The counterweight slider 19 on the disc 14 is kept in the outer position under the action of centrifugal force. The connecting rod 20 and the rotating seat 17 keep the slide 15 in the position of sliding towards the retaining ring 13, and the spring 16 is kept in a compressed state. The sealing plate 3 of the sealing assembly is kept in the open position, the air outlet 101 is unobstructed, and the heated air can be discharged smoothly.

[0064] When the heater stops running, the motor 11 stops working, the rotation of the rotating rod 10 stops, and the counterweight slider 19 on the disc 14 loses the effect of centrifugal force. Under the elastic force of the spring 16, it begins to slide towards the center of the disc 14. The inward sliding of the counterweight slider 19 drives the rotating seat 17 to move towards the disc 14 through the connecting rod 20. The movement of the rotating seat 17 drives the slide 15 to slide along the rotating rod 10 towards the disc 14. The sliding of the slide 15 causes the spring 16 to gradually return to its initial compressed state.

[0065] The sliding of the slide block 15 drives the U-shaped block 5 to move toward the disk 14 via the L-shaped rod 21. The movement of the U-shaped block 5 causes the sealing plate 3 to start rotating in the opposite direction. Since the sealing plates 3 are connected by the connecting piece 4, the reverse rotation of one sealing plate 3 will drive the other sealing plates 3 to rotate in the opposite direction in sequence, eventually causing the entire sealing assembly to switch from the open position to the closed position, and the air outlet 101 is resealed.
