Abstract
Description
Technical Field
[0001] This utility model relates to the field of hair dryer technology, and in particular to a detachable air inlet dustproof component for hair dryers. Background Technology
[0002] Hair dryers, an indispensable small appliance in modern daily life, are commonly used for drying hair. When in operation, a hair dryer uses an electric motor to drive fan blades, drawing air in through the rear air inlet. After being heated by the heating element, hot air is blown out through the front air outlet. This seemingly unidirectional airflow circulation, however, can easily lead to hair, hairspray, and other debris entering the hair dryer over time. This can affect the normal operation of the internal motor, reduce the lifespan of the hair dryer, and even cause the debris accumulated near the heating element to carbonize at high temperatures, producing odors or even posing a short circuit hazard. To address this, we have proposed a detachable air inlet dustproof component for hair dryers. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a detachable air inlet dustproof component for hair dryers.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a detachable air inlet and dustproof assembly for a hair dryer, comprising a main housing and a rear housing. The main housing has a front air duct portion and a rear handle portion. The front air duct portion is connected to the rear handle portion, and the rear handle portion is connected to the rear housing. The rear housing has an air inlet mesh and a slot. A detachable protective sheet is inserted into the slot. The protective sheet is used to prevent debris from entering the hair dryer. The rear handle portion of the main housing has a limiting inner sidewall, which contacts the lateral straight edge of the filter plate portion of the protective sheet.
[0005] To elaborate further, the protective sheet has a handle on the upper side of the filter plate and a positioning groove on the lower side of the filter plate.
[0006] To elaborate further, the rear shell is provided with a positioning block that mates with the positioning groove.
[0007] To elaborate further, the handle portion of the protective sheet is provided with a pry opening.
[0008] To elaborate further, the upper and lower sides of the rear shell are provided with openings, and the air inlet mesh is exposed from the openings.
[0009] The beneficial effects of this utility model are as follows: This utility model adopts a protective sheet structure design, which can filter the air after entering the air inlet net and intercept debris such as hair and hairspray, thereby avoiding affecting the normal operation of the motor inside the hair dryer. In addition, the protective sheet can be removed for cleaning and can be recycled. Attached Figure Description

[0016] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.
[0017] Combined with appendix Figure 1 To be continued Figure 3 As shown, a detachable air inlet and dustproof assembly for a hair dryer includes a main housing 10 and a rear cover 30. The main housing 10 has a front air duct portion 11 and a rear handle portion 12. The front air duct portion 11 is connected to the rear handle portion 12, and the rear handle portion 12 is connected to the rear cover 30. The rear cover 30 is specifically fitted onto the rear handle portion 12 of the main housing 10. An air inlet mesh 40 is provided at the rear cover 30. The air inlet mesh 40 is specifically rolled into a cylindrical shape and placed inside the rear cover 30. The air inlet mesh 40 has several air inlet holes 41, as shown in the attached figure. Figure 5 As shown, the rear cover 30 has a slot 31, and a removable protective plate 20 is inserted into the slot 31. The protective plate 20 is used to prevent hair, hairspray and other debris from entering the hair dryer.
[0018] Combined with appendix Figure 3 and attached Figure 4As shown, the rear handle portion 12 of the main housing 10 is provided with a limiting inner sidewall 121, which contacts the lateral straight edge 211 of the filter plate portion 21 of the protective sheet 20. The upper and lower sides of the rear housing 30 are provided with openings 33, through which the air inlet mesh 40 protrudes. The protective sheet 20 can be flexibly inserted and removed into the slot 31 of the rear housing 30. When the hair dryer is working, air is drawn into the hair dryer through the air inlet mesh 40. The protective sheet 20 filters the air entering the air inlet mesh 40, intercepting hair, hairspray, and other debris, thereby preventing interference with the normal operation of the internal motor of the hair dryer.
[0019] Combined with appendix Figure 2 To be continued Figure 4 As shown, the protective sheet 20 has a handle 22 on the upper side of the filter plate section 21, and the handle 22 of the protective sheet 20 has a pry opening 221. When the protective sheet 20 has intercepted a large amount of debris, it can be removed from the rear cover 30 to clean its filter plate section 21, thus achieving reusability. Specifically, the protective sheet 20 can be removed from the rear cover 30 by prying open the pry opening 221 of the handle 22.
[0020] In addition, a positioning groove 23 is provided on the lower side of the filter plate section 21. A positioning block section 32 that mates with the positioning groove 23 is provided at the rear housing 30. (See attached image) Figure 2 As shown, after the protective sheet 20 is removed and cleaned, the cleaned protective sheet 20 can be directly inserted into the slot 31 of the rear shell 30. When the positioning groove 23 of the protective sheet 20 is engaged with the positioning block 32 of the rear shell 30, the reinstallation of the protective sheet 20 is completed. The operation is simple and convenient, and can effectively improve the service life of the hair dryer.
