Description

Technical Field

[0001] This utility model relates to an improvement of a hair dryer, particularly in the filtration of the air intake. Background Technology

[0002] Although there are many types of hair dryers on the market, each with its own unique appearance and functions, their basic structure is largely the same. The main components include the housing, handle, motor, fan blades, heating element, air deflector, switch, and power cord. These components work together to perform the various functions of the hair dryer.

[0003] Modern high-speed hair dryers typically have the air inlet located on the handle, while the heating element is positioned in the head. Air enters from the handle, heats up, and is then expelled as hot air. However, some hair dryers lack a filter, or have a filter with excessively large pores that provides poor filtration. This allows debris such as hair, dust, and lint to easily enter the air inlet. Once inside, this debris can become entangled in the heating element, affecting heat dissipation, reducing the hair dryer's performance and lifespan. Furthermore, the debris can produce unpleasant odors at high temperatures and may even pose a fire hazard.

[0004] The air intake channel is prone to blockage. After prolonged use, even with a filter, the air intake channel may become clogged with accumulated dust and debris, resulting in reduced airflow and weaker airflow, thus affecting drying efficiency. Moreover, cleaning the air intake channel is relatively difficult and requires professional tools and certain operating skills. Utility Model Content

[0005] To overcome the inconvenience of cleaning current high-speed hair dryers, this utility model provides a high-speed hair dryer with large air volume and anti-winding properties.

[0006] The technical solution of this utility model to solve its technical problem is: a high-speed blower with high air volume and anti-winding capability, comprising a housing, a handle at the lower end and a head at the upper end of the housing, the handle being connected to the head, and an air inlet area with a grid at the lower part of the handle; a heating mechanism inside the head; a display screen on the rear side of the head; an air outlet at the front end of the head, with a blower head detachably mounted on the air outlet; a fan inside the handle, which delivers air from the air inlet area at the lower end to the head; a detachable handle at the lower end of the handle, with the air inlet area located around the detachable handle; a coarse filter cartridge detachably mounted inside the detachable handle, and a fine filter cartridge inside the coarse filter cartridge, the fine filter cartridge being detachably mounted inside the lower end of the handle; the fine filter cartridge has a higher filtration accuracy than the coarse filter cartridge. The fine filter cartridge uses a 400-mesh filter, and the coarse filter cartridge uses a 20-mesh filter.

[0007] Our detachable handle head can be connected to the handle using a screw connection.

[0008] Furthermore, the coarse filter cartridge has snap-fit ​​ears on both sides of its upper end, and the detachable handle has snap-fit ​​grooves. When the coarse filter cartridge is installed in the detachable handle, the snap-fit ​​ears snap into the snap-fit ​​grooves.

[0009] A preferred number of latches is two.

[0010] To facilitate the installation of the filter cartridge and air intake, the lower end of the handle is provided with a hollow mounting bracket, the lower end of which is provided with a mounting head. A fan is provided above the mounting bracket, and the fine filter cartridge is detachably fixed on the mounting bracket.

[0011] A preferred embodiment of a fine filter cartridge structure includes a filter cartridge frame and a fine filter cartridge surface integrally cast onto the filter cartridge frame.

[0012] In a preferred embodiment of a detachable fine filter cartridge, the lower inner side of the filter cartridge holder is provided with a fixed ear with a hole, and the lower end of the mounting handle is provided with an ear groove. The fine filter cartridge is detachably fixed to the mounting handle by inserting the fixed ear into the ear groove, and fixing screws pass through the fixed ear and are fixed to the ear groove.

[0013] To enhance sealing performance, a rubber ring is provided inside the detachable handle, with the upper end of the rubber ring resting against the lower end of the fine filter cartridge.

[0014] A preferred embodiment of a coarse filter cartridge structure is a plastic ring at the upper end and a metal mesh at the lower end.

[0015] For ease of cleaning, both the coarse filter cartridge and the fine filter cartridge have stainless steel mesh surfaces.

[0016] To reduce costs, the surface of the fine filter cartridge is made of nylon mesh.

[0017] When in use, the air entering through the grille inlet of this utility model undergoes two stages of filtration: the first is a 20-mesh coarse filter, and the second is a 400-mesh fine filter. Coarser hairs are intercepted at the coarse filter, while finer dust and debris are intercepted at the 400-mesh fine filter, thus achieving graded filtration. The coarse filter handles the majority of the filtered material. The coarse filter is mounted on a detachable handle, which makes it relatively easy to remove and clean the coarse filter.

[0018] Over time, a layer of dirt will accumulate on the filter cartridge. To maintain the filter cartridge, we need to remove the detachable cartridge head, then unscrew the screws on the fixing ears of the filter cartridge, then remove the filter cartridge for cleaning, and then reinstall it.

[0019] The beneficial effects of this invention are as follows: 1. The high-speed hair dryer uses a two-stage filtration system, blocking most dust, impurities, and hair from entering the hair dryer. This effectively prevents dust from accumulating on key components such as the motor and heating wire, reducing the probability of malfunctions such as poor heat dissipation and short circuits caused by dust accumulation, and extending the service life of each component. 2. The coarse filter intercepts larger dust particles, hair, and other impurities, preventing them from entering the hair dryer. The fine filter further filters finer dust, pollen, bacteria, and other harmful substances. This results in cleaner air reaching the hair, reducing contact between the hair and dirt and bacteria, lowering the risk of hair contamination and damage, helping to maintain healthy and shiny hair, reducing damaging substances, and improving hair care effects. 3. The two filters are independently designed, allowing for separate disassembly and cleaning. When the coarse filter accumulates a large amount of large particles, the user can easily remove it from the handle for cleaning; the operation is simple and quick. Similarly, the fine filter can be removed separately for deep cleaning or replacement. This independent maintenance method reduces maintenance complexity and costs, while also allowing for timely restoration of filter performance and ensuring normal equipment operation.

[0037] In this embodiment, the air entering through the grille inlet undergoes two stages of filtration: a 20-mesh coarse filter cartridge 8 and a 400-mesh fine filter cartridge 9. This allows coarser hairs to be intercepted at the coarse filter, while finer dust and debris are intercepted at the 400-mesh fine filter cartridge 9, thus achieving graded filtration. The coarse filter handles the majority of the filtered material. The coarse filter cartridge 8 is mounted on a detachable handle 7, which is relatively easy to remove, allowing for convenient removal and cleaning of the coarse filter cartridge 8.

[0038] The beneficial effects of the two embodiments described above are as follows: 1. The high-speed hair dryer uses a two-stage filtration system, blocking most dust, impurities, and hair from entering the hair dryer. This effectively prevents dust from accumulating on key components such as the motor and heating wire, reducing the probability of malfunctions such as poor heat dissipation and short circuits caused by dust accumulation, and extending the service life of each component. 2. The coarse filter intercepts larger dust particles, hair, and other impurities, preventing them from entering the hair dryer. The fine filter further filters finer dust, pollen, bacteria, and other harmful substances. This results in cleaner air reaching the hair, reducing contact between the hair and dirt and bacteria, lowering the risk of hair contamination and damage, helping to maintain healthy and shiny hair, reducing damaging substances, and improving hair care results. 3. The two filters are independently designed, allowing for separate disassembly and cleaning.
