Description

Technical Field

[0001] This application relates to the field of hot air blower technology, and in particular to a hot air blower for furniture repair. Background Technology

[0002] In the field of furniture repair, hot air blowers are core equipment for processes such as drying, edge banding, and heat shrinking. Their performance is directly related to repair efficiency and work safety. Traditional hot air blowers generally adopt an open air intake structure, which draws external air into the heating chamber through high-speed airflow for heating before outputting it.

[0003] Furniture repair sites commonly contain high concentrations of suspended particulate matter, such as micron-sized wood chips from wood sanding and organic dust from paint polishing. These substances can easily enter the equipment with the airflow.

[0004] When wood dust encounters a high-temperature heat source in the heating chamber, it may cause a deflagration accident. At the same time, although ordinary hot air blowers are generally equipped with metal filters, the static filtration structure is prone to forming a dense dust layer, which requires frequent disassembly and cleaning.

[0005] In other words, existing technologies have the following technical problems: ordinary hot air blowers are prone to sucking in sawdust when used in furniture repair sites, which can lead to ignition. Therefore, a hot air blower for furniture repair is proposed to address the above problems. Summary of the Invention

[0035] Please see Figure 1-5 As shown, a hot air blower for furniture repair includes:

[0036] A fixed base 1 is provided, and a heater 4 is fixedly connected to the upper surface of the fixed base 1. A fan 3 is fixedly connected to the heater 4. One end of an output pipe 301 is fixedly connected to the output end of the fan 3, and the other end of the output pipe 301 extends into the interior of the heater 4.

[0037] An input pipe 302 is fixedly connected to the input end of the fan 3;

[0038] The filter assembly 5 is fixedly mounted on the input pipe 302. The filter assembly 5 is used to automatically filter the intake air and has an anti-clogging structure.

[0039] Through the above technical solution, the filter component 5 can effectively filter the intake air and has an anti-clogging structure. While filtering, it achieves an automatic anti-clogging effect, which can automatically collect the intercepted wood chips and dust. It is particularly suitable for use in furniture repair environments.

[0040] The output end of the heater 4 is fixedly connected to a hot air output pipe 401;

[0041] The filter assembly 5 includes a sleeve 501, a fixed guide rod 502, a connecting circular plate 503, a filter screen 504, and a spring 505. The sleeve 501 is fixedly installed at the input pipe 302. The fixed guide rod 502 is fixedly connected to the inner wall of the sleeve 501. The fixed guide rod 502 passes through the connecting circular plate 503 and slides with the connecting circular plate 503.

[0042] An air vent is provided at the middle position of the connecting circular plate 503, and a filter screen 504 is fixedly connected to the air vent of the connecting circular plate 503. Through this technical solution, the drawn-in air enters the inner cavity of the input pipe 302 through the filter screen 504, thereby filtering dust and wood chips and preventing them from entering the interior of the heater 4 and causing ignition.

[0043] One end of a spring 505 is fixedly connected to the side of the connecting circular plate 503, and the other end of the spring 505 is fixedly connected to the inner wall of the sleeve 501.

[0044] The anti-clogging structure includes a fixed shaft 506, a disc 507, a turbine 508, a connecting rod A 509, and a connecting rod B 510. The fixed shaft 506 is fixedly installed on the inner wall of the input pipe 302, and the disc 507 is rotatably connected to one end of the fixed shaft 506.

[0045] A plurality of turbines 508 are fixedly connected to the arc-shaped wall of the disk 507. Through this technical solution, the turbines 508 are configured to rotate when air is drawn in, thereby driving the disk 507 to rotate.

[0046] One end of a connecting rod A509 is rotatably connected to the side wall of the disc 507, and the other end of a connecting rod B510 is rotatably connected to the other end of the connecting rod A509. The other end of the connecting rod B510 extends to the side wall of the filter screen 504 and is fixedly connected to the filter screen 504. Through this technical solution, the rotation of the disc 507 can drive one end of the connecting rod A509 to move in a ring, thereby driving the connecting rod B510 to move back and forth, thereby driving the filter screen 504 to vibrate back and forth. Through vibration, the sawdust and other particles on the surface of the filter screen 504 can be vibrated off, realizing the function of automatic cleaning and avoiding the clogging caused by the continuous accumulation of dust and sawdust on the filter screen 504.

[0047] The sleeve 501 is provided with a recycling structure, which includes an outlet 511, a collection chamber 512, a limiting slider 513, a limiting lock 514, a pull rod 515 and a limiting spring 516. The outlet 511 is fixedly provided at the arc-shaped wall of the sleeve 501 and communicates with the interior of the sleeve 501. The collection chamber 512 is slidably inserted into the outlet 511.

[0048] A slot is provided on the side of the outlet 511, and an inner cavity is provided on the side of the collection chamber 512. A limit slider 513 is slidably connected in the inner cavity of the collection chamber 512. A limit latch 514 is fixedly connected to the side wall of the limit slider 513. One end of the limit latch 514 extends into the slot on the side of the outlet 511. One end of a pull rod 515 is fixedly connected to the other side wall of the limit slider 513. The other end of the pull rod 515 penetrates the inner wall of the collection chamber 512 and extends to the outside of the wall. One end of a limit spring 516 is fixedly connected to the side wall of the limit slider 513. The other end of the limiting spring 516 is fixedly connected to the inner wall of the collection chamber 512. Through this technical solution, the limiting lock 514 can be used to fix the collection chamber 512 and the discharge port 511. When the dust and wood chips that have been vibrated and fallen off fall, they can fall into the inner cavity of the collection chamber 512 through the discharge port 511, thus realizing the recycling function. When cleaning is required, the lever 515 can be manually moved to drive the limiting slider 513 to move, thereby moving the limiting lock 514 and separating it from the discharge port 511. This allows the collection chamber 512 to be removed and the wood chips and dust inside to be cleaned.

[0049] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this application does not involve any improvement to the software and methods.

[0050] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
