[0021] The present invention will be further described below with reference to the embodiments.

[0022] See also Figure 1-3 The utility model provides a low-noise heater, comprising a heater cover 1 and a heater shell 2, wherein the heater cover 1 and the heater shell 2 are fixed with screws to form an integrated structure;

[0023] Specifically, after the heater cover 1 is disassembled from the heater shell 2, the equipment inside the heater can be easily repaired or replaced, which simplifies the assembly process and reduces the maintenance burden.

[0024] Furthermore, a ventilation unit 21 is provided on the outer wall of one end of the heater shell 2, and a fixing seat 3 is fixed on both sides of the ventilation unit 21 and located inside the heater shell 2. The ventilation unit 21 is composed of a plurality of ventilation holes located on the bottom wall and both sides of the heater shell 2, and the ventilation holes are all arranged in a strip-shaped structure;

[0025] Specifically, the ventilation unit 21 is located on the outer wall of one end of the heater shell 2. It is a channel for exchanging air between the heater and the outside world. The dense ventilation holes can also prevent foreign matter from entering the draft assembly 4. It is worth noting that in the heating state, the fan 48 in the draft assembly 4 on one side rotates to drive the airflow through the ventilation unit 21 into the air guide frame 6. The airflow is effectively heated when passing through the PTC heating module, and the generated hot air is blown out from the bottom end of the air guide frame 6. In the ventilation state, the fan 48 in the draft assembly 4 on the other side rotates to drive the airflow through the ventilation unit 21 and blow it directly out from the end of the heater shell 2.

[0026] Furthermore, the fixing base 3 is detachably connected to an air induction assembly 4, and the air induction assembly 4 includes an air tube 41 located in the fixing base 3. Two sliding cavities 42 are symmetrically provided in the air tube 41, and a second slider 43 is slidably embedded in each of the sliding cavities 42. A control rod 44 is fixedly connected to one side of the second slider 43, and one end of the control rod 44 is arranged to pass through the air tube 41. A lock hole 45 is opened on one side of the sliding cavity 42, and the lock hole 45 is adapted to the structure of the locking block 34.

[0027] Specifically, under the elastic force of the spring 33, the air duct 41 is fixed in a flexible support state. When the air duct 41 needs to be disassembled for replacement or cleaning, the control rod 44 can be pressed to make the reduced diameter end of the locking block 34 extend out of the lock hole 45, thereby easily pulling out the air duct 41.

[0028] Furthermore, a triangular bracket 46 is fixedly connected to the inner wall of the air duct 41, a driving motor 47 is fixedly sleeved in the triangular bracket 46, and a fan 48 is fixedly connected to the output end of the driving motor 47;

[0029] Specifically, when the drive motor 47 is powered on and running, it can drive the fan 48 to rotate, thereby generating airflow. It is worth noting that the gradually narrowing diameter of the inner wall of the air duct 41 is conducive to enhancing the wind force of the airflow guided by the fan 48.

[0030] Furthermore, guide grooves 49 are provided on both sides of the air duct 41, and the guide grooves 49 are connected to the lock hole 45;

[0031] Specifically, the design of the guide groove 49 allows the locking block 34 to be inserted through the guide groove 49 and moved to the locking hole 45 position, which is beneficial for installing the air cylinder 41.

[0032] Furthermore, a sound-absorbing cover 5 is provided on the outer side of each of the fixing bases 3;

[0033] Specifically, the silencer cover 5 can effectively isolate and absorb the noise generated by components such as the drive motor 47 and the fan 48. The silencer cover 5 is made of sound insulation materials, such as sound-absorbing cotton, foam or other sound-absorbing materials. These materials can absorb sound waves, reduce the reflection and propagation of sound waves, and thus reduce noise.

[0034] Furthermore, a column 31 is fixedly connected to both sides of the inner wall of the fixing seat 3, and a first slider 32 is slidably connected to the inside of the column 31. A spring 33 is fixedly connected between one side of the first slider 32 and the inner end wall of the column 31, and a locking block 34 is fixed to the other side of the first slider 32. The size of the locking block 34 is gradually narrowed at the end that passes through the column 31.

[0035] Specifically, the setting of the spring 33 effectively reduces the noise generated by the operation of the drive motor 47 and the fan 48 by isolating and absorbing vibrations, reducing resonance, and reducing friction and impact, thereby improving the quietness of the operation of the heater and the user experience.

[0036] Furthermore, one side of one of the fixing bases 3 is fixedly connected to an air guide frame 6 with a built-in PTC heating module, and the bottom end of the air guide frame 6 extends to the outside of the heater shell 2;

[0037] Specifically, the air guide frame 6 has a built-in PTC heating module, which is an efficient and safe heating element. The PTC heating module can heat up quickly under the action of electric energy and has a self-temperature control characteristic, that is, when the temperature reaches a certain value, the resistance increases and the power decreases, thereby maintaining a constant temperature.

[0038] Working principle: When in use, adjust the air duct 41 to align with the fixing base 3, align the locking block 34 with the guide groove 49 and insert it until the locking block 34 moves to the lock hole 45 position. Under the elastic action of the spring 33, the locking block 34 will be inserted into the sliding cavity 42, so that the air duct 41 is in a flexible support state. After the drive motor 47 is energized, the drive motor 47 drives the fan 48 to rotate. The rotation of the fan 48 drives the air flow into the air guide mold frame 6. The air flow is effectively heated when passing through the PTC heating module, and the hot air generated is blown out, which can significantly increase the indoor temperature. In this process, the vibration generated by the operation of the drive motor 47 and the fan 48 is effectively buffered by the spring 33, which can reduce noise. The silencer 5 can further reduce the impact of noise, making the heater run quieter. When maintenance is needed, only the control lever 44 needs to be manually pressed. The control lever 44 pushes the end of the locking block 34, so that the reduced diameter end of the locking block 34 extends out of the lock hole 45. At this time, the air duct 41 can be easily pulled out for replacement or cleaning.
