[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 4 As shown in the embodiment of this utility model, a rapid heating device for a heater includes a first fixing block 2. A locking component 1 is installed inside the first fixing block 2. The locking component 1 includes two locking posts 11. A circular plate 12 is fixedly connected to the opposite surfaces of the two locking posts 11. A first handle 13 is fixedly connected above the circular plate 12. Springs 14 are fixedly connected to the opposite surfaces of the two circular plates 12. The first fixing block 2 is slidably connected to the outer wall of the locking posts 11. The first fixing block 2 includes two second fixing blocks 21. A T-shaped circular groove 22 is formed on the side of each second fixing block 21 that is far apart from the others. A square groove is formed on the upper part of the inner wall of the T-shaped circular groove 22. The inner wall of the square hole 23 and the T-shaped groove 22 is slidably connected to the outer wall of the snap-fit ​​post 11 and the circular plate 12. The inner wall of the square hole 23 is slidably connected to the outer wall of the first handle 13. The inner wall of the T-shaped groove 22 is fixedly connected to the other end of the spring 14. The outer wall of the snap-fit ​​post 11 is slidably connected to the first filter screen 3. The first filter screen 3 includes two circular frames 31. The inner side of the circular frame 31 is fixedly connected to the second filter screen 32. The top of the circular frame 31 is fixedly connected to the fixed plate 33. The top of the fixed plate 33 is fixedly connected to the second handle 34. The fixed plate 33 has a snap-fit ​​hole 35 corresponding to the snap-fit ​​post 11. The inner wall of the snap-fit ​​hole 35 is slidably connected to the outer wall of the snap-fit ​​post 11.

[0023] The locking component 1 and the first fixing block 2 cooperate to allow the first filter screen 3 to be quickly disassembled. During use, pull the first handle 13 to slide the circular plate 12 against the T-shaped groove 22, causing the locking post 11 to slide against the T-shaped groove 22 and the locking hole 35, disengaging from the locking hole 35. Grasp the second handle 34 and pull upwards to slide the circular frame 31 against the arc-shaped sliding groove 42, thus completing the disassembly and cleaning. During installation, pull the first handle 13 to place the locking post 11 into the inner wall of the T-shaped groove 22, then insert the circular frame 31 into the arc-shaped sliding groove 42, and release the first handle 1. 3. Spring 14 pushes the circular plate 12 to slide through its elastic force, thereby allowing the locking post 11 to slide into the locking hole 35 for fixation, thus completing the installation. The second filter screen 32 is a consumable part and may be damaged after long-term use. Traditional filters are often fixed with screws or integrated with the body. Replacement requires professional tools or disassembly of the body, which is complicated. The locking component 1 structure allows users to remove the second filter screen 32 by themselves without professional knowledge, avoiding the normal use of the heater due to damage to the second filter screen 32, or even dust entering the internal components and causing malfunctions.

[0024] Without the need for screwdrivers or other tools, the second filter 32 can be quickly disassembled and installed by pulling the first handle 13 and the second handle 34. Users can complete the disassembly or installation within 10 seconds, which greatly reduces the threshold for cleaning and replacing the filter, and is especially suitable for users with weaker operating skills such as the elderly and children.

[0025] like Figure 5 As shown, a first cylindrical chamber 4 is slidably connected to the outer wall of the circular frame 31. The first cylindrical chamber 4 includes a second cylindrical chamber 41. The second cylindrical chamber 41 has arc-shaped sliding grooves 42 on both the front and rear sides above. The front of the inner wall of the second cylindrical chamber 41 is an air outlet 43, and the rear of the inner wall of the second cylindrical chamber 41 is an air inlet 44. Support legs 45 are fixedly connected to the front and rear sides below the second cylindrical chamber 41. The inner wall of the arc-shaped sliding groove 42 is slidably connected to the outer wall of the circular frame 31. The upper part of the second cylindrical chamber 41 is fixedly connected to the lower part of the second fixing block 21. A heating mechanism 6 is provided near the middle of the inner wall of the second cylindrical chamber 41, and a blower mechanism 5 is provided at the rear of the inner wall of the second cylindrical chamber 41.

[0026] Both the blower mechanism 5 and the heating mechanism 6 are existing technologies. The principle of the blower mechanism 5 is that the motor drives the fan blades to rotate and blow air. The principle of the heating mechanism 6 is that when current passes through heating elements such as resistance wire and PTC ceramic, electrical energy is converted into heat energy, which raises the temperature of the heating elements and heats the surrounding air. This will not be elaborated further here.

[0027] Working principle: The locking component 1 and the first fixing block 2 cooperate to quickly disassemble the first filter screen 3. During use, pull the first handle 13 to slide the circular plate 12 against the T-shaped groove 22, causing the locking post 11 to slide against the T-shaped groove 22 and the locking hole 35, disengaging from the locking hole 35. Grasp the second handle 34 and pull upwards to slide the circular frame 31 against the arc-shaped sliding groove 42, thus completing disassembly and cleaning. During installation, pull the first handle 13 to place the locking post 11 into the inner wall of the T-shaped groove 22, then insert the circular frame 31 into the arc-shaped sliding groove 42, and release the first handle. Hand 13 causes spring 14 to push the circular plate 12 to slide through elastic force, thereby allowing the locking post 11 to slide into the locking hole 35 for fixation, thus completing the installation. The second filter screen 32 is a consumable part and may be damaged after long-term use. Traditional filters are often fixed with screws or integrated with the body, requiring professional tools or disassembly of the body for replacement, which is complicated. The locking component 1 structure allows users to replace the second filter screen 32 themselves without professional knowledge, avoiding the normal use of the heater due to damage to the second filter screen 32, or even allowing dust to enter the internal components and cause malfunctions.

[0028] Without the need for screwdrivers or other tools, the second filter 32 can be quickly disassembled and installed by pulling the first handle 13 and the second handle 34. Users can complete the disassembly or installation within 10 seconds, which greatly reduces the threshold for cleaning and replacing the filter, and is especially suitable for users with weaker operating skills such as the elderly and children.

[0029] Both the blower mechanism 5 and the heating mechanism 6 are existing technologies. The principle of the blower mechanism 5 is that the motor drives the fan blades to rotate and blow air. The principle of the heating mechanism 6 is that when current passes through heating elements such as resistance wire and PTC ceramic, electrical energy is converted into heat energy, which raises the temperature of the heating elements and heats the surrounding air. This will not be elaborated further here.
