Description

Technical Field

[0001] This utility model relates to the field of luggage accessories, and more specifically, to a hair dryer bracket and a luggage. Background Technology

[0002] With the significant improvement in people's quality of life and the increasing frequency of travel, suitcases, as an indispensable tool for daily travel, have seen their versatility and ease of use gradually become the focus of consumers' attention when purchasing them. In diverse scenarios such as travel and business trips, users often face various practical problems, among which the need for damp clothes and quick drying is particularly prominent. During long-distance travel, clothes may become damp due to weather changes or unexpected rain; during business trips, users also hope to dry their clothes quickly in order to maintain a neat and professional appearance. However, traditional suitcases have extremely limited functions, only meeting the basic needs of storage and carrying items, and cannot provide additional functions such as clothes drying, which often leaves users feeling helpless when encountering the above problems.

[0003] To address this issue, some existing technologies in the industry have begun to explore creating holes in suitcases and using hair dryers to dry clothes inside, achieving rapid drying and providing greater convenience for users. However, from the perspective of practical application and technological development, current related technical solutions still have many significant shortcomings.

[0004] For example, as shown in Chinese utility model publication CN222109484U, firstly, regarding structural stability, some existing solutions lack a stable and reliable support structure for the hairdryer bracket. Due to this inadequate support structure, the hairdryer is not securely installed on the suitcase, making it prone to shaking or loosening during use. This instability not only affects the user experience, causing unease and inconvenience, but also potentially damages the device and shortens its lifespan. For instance, during operation, the hairdryer's airflow and slight shaking can cause it to detach from the holes in the suitcase, requiring the user to hold it constantly, resulting in inconvenience.

[0005] Secondly, low space utilization is another prominent problem with existing solutions. The conical sleeve of the air blower bracket is built into the suitcase, extending inwards from wide to narrow, thus occupying valuable internal storage space. For users, suitcase storage space is extremely important; with the limited space occupied by the air blower bracket, the number of items a user can store is reduced, undoubtedly decreasing the suitcase's practicality. This space occupation can cause significant inconvenience, especially on long journeys or when carrying a large amount of items.

[0006] Furthermore, inconvenience is also a problem that cannot be ignored in existing technical solutions. Because clothes vary in thickness, drying times differ. During use, users need to constantly adjust the position of the clothes to accommodate the hairdryer, which undoubtedly increases the difficulty and time cost for users.

[0007] Furthermore, existing hair dryer bracket structures have poor adaptability, making it difficult to accommodate hair dryers of different sizes and shapes. The market offers a wide variety of hair dryers in various sizes and shapes, while existing brackets often only fit specific sizes and shapes. This can lead to installation difficulties or insecure installation when users replace hair dryers or use different brands, further limiting their application. Utility Model Content

[0008] The present invention aims to overcome the problems of insufficient structural stability, low space utilization and inconvenience of use in the prior art.

[0009] The technical solution adopted by this utility model is to provide a wind tunnel support, including a base and a conical sleeve. An air inlet is opened in the middle of the base, and the conical sleeve has a through air duct in the middle. It has a narrow end and a wide end. The narrow end is connected to the base so that the air duct is connected to the air inlet.

[0010] This solution uses a base as a support frame to provide stability and support, allowing the hair dryer to be securely installed on the suitcase. At the same time, the base serves as the connection point between the hair dryer bracket and the suitcase, ensuring that the hair dryer will not loosen or fall off during use, thus guaranteeing safety and reliability.

[0011] The air inlet in the center of the base serves as a channel for air to enter the duct, ensuring smooth airflow and providing the necessary air circulation for drying clothes. Simultaneously, the tapered design of the sleeve guides and concentrates the air entering from the inlet, forming a stable airflow that flows from the wide end to the narrow end, increasing the speed and force of the airflow and improving drying efficiency. The wide end of the tapered sleeve acts as the starting point for the airflow out of the duct, and the narrow end as the ending point, directing the concentrated airflow towards the clothes to be dried. This allows the air to flow more quickly within the suitcase, significantly improving the drying effect. Furthermore, the tapered sleeve features a detachable design, allowing for easy installation or removal as needed, facilitating carrying and storage, and increasing flexibility in use.

[0012] Furthermore, the tapered sleeve is designed with a telescopic structure. When the air blower bracket is not in use, the tapered sleeve can be retracted to its shortest state, significantly reducing the space occupied by the tapered sleeve. This makes the tapered sleeve easy to carry and store. Whether placed in a suitcase or a backpack, it will not take up too much space, making it convenient for users to travel.

[0013] Furthermore, the conical sleeve can be designed as a stepped telescopic structure. While possessing telescopic functionality, the stepped structure also provides multi-level support, ensuring a stable connection between the sleeve and the base. During operation, this multi-level support structure effectively disperses the pressure generated by the wind, reducing sleeve swaying and deformation, ensuring the blower remains stably connected to the blower support during operation, thus improving reliability. The multi-level nested annular structure, with its progressively increasing size from the narrow end to the wide end, allows the blower support to be adaptively adjusted and nested for different blower outlet specifications, improving the compatibility of the blower support with various types of blowers.

[0014] Furthermore, the multi-level annular structure includes a narrow-end support ring, a wide-end support ring, and a multi-level transition support ring connecting the narrow-end and wide-end support rings. The narrow-end support ring is embedded in the air inlet of the base, providing precise positioning for the connection between the conical sleeve and the base while also ensuring the conical sleeve is securely mounted on the base. Moreover, it allows airflow to smoothly enter the luggage compartment from the air inlet, reducing airflow loss and resistance at the connection point, improving the ventilation efficiency of the air duct, and ensuring that hot air can be stably and efficiently delivered to the interior of the luggage compartment.

[0015] Furthermore, the thickness of the multi-stage transition support ring is designed to be less than that of the narrow-end and wide-end support rings, and it is made of a flexible material. This combination gives the transition support ring a flexible structural characteristic with less supporting force than the narrow-end and wide-end support rings. This allows for relative offset between the narrow-end and wide-end support rings. When the hair dryer is working, hot air enters the air duct through the air inlet. Users can adjust the direction of the air duct by adjusting the relative offset between the narrow-end and wide-end support rings, ensuring the hot air is blown more smoothly onto the clothes to be dried, improving the drying effect. Simultaneously, the pressure generated by the hot air and the external force from moving the suitcase will cause certain stress on the conical sleeve. The relative offset between the narrow-end and wide-end support rings allows for better stress distribution on the conical sleeve, preventing stress concentration in one area, thereby reducing the risk of deformation and damage to the conical sleeve and improving the structural stability and reliability of the hair dryer support.

[0016] Furthermore, the base includes an inner support, an outer support, and fasteners. The inner and outer supports are clamped and installed on the luggage compartment, and the fasteners firmly connect the inner and outer supports together to form a stable base structure that can withstand the vibration and external forces generated during the operation of the wind duct, ensuring that the inner and outer supports will not loosen or separate, and guaranteeing the overall stability of the wind duct support.

[0017] Furthermore, the inner or outer bracket has an air inlet sidewall at the corresponding air inlet position. After the inner and outer brackets are connected by fasteners, the air inlet sidewall extends to the outer or inner bracket. This increases the strength of the mating structure and guides and constrains the airflow to a certain extent, preventing the airflow from leaking out from the gap between the inner and outer brackets. This allows the airflow to enter the luggage compartment more concentratedly and smoothly, improving the utilization efficiency of hot air and enhancing the drying effect.

[0018] Furthermore, the outer support has a cavity that can accommodate the conical sleeve, and is equipped with an openable cover plate to cover the cavity. When the conical sleeve is not in use, the telescopic structure can retract it into the cavity, and the closing of the cover plate makes the appearance of the suitcase and air duct support neat and beautiful. The area of ​​the openable cover plate must be larger than the maximum cross-sectional area of ​​the conical sleeve to ensure that the cover plate can completely cover the cavity and the conical sleeve inside when closed. This prevents dust, debris, etc. from entering the cavity, keeping the conical sleeve clean, and also prevents it from being squeezed or bumped by the outside world during transportation or storage.

[0019] When the air duct bracket of the above solution is integrated into the suitcase, the air duct bracket is installed on the main body of the suitcase, the air inlet is connected to the inner cavity of the main body of the suitcase, the base is fixed to the shell of the main body of the suitcase, and the conical sleeve extends outward from the shell of the main body of the suitcase. The base of the air duct bracket includes an inner bracket set inside the shell and an outer bracket set outside the shell. The two are connected by fasteners that penetrate the shell of the suitcase. The inner bracket or the outer bracket has an air inlet sidewall corresponding to the air inlet. After the inner bracket and the outer bracket are connected by fasteners, the air inlet sidewall extends through the shell to the outer bracket or the inner bracket.

[0020] Furthermore, a flexible lining is built into the main body of the suitcase, with an internal air inlet hole that connects to the air inlet hole. This allows the hot air from the hairdryer to enter the suitcase smoothly and unobstructed through the air inlet hole and the internal air inlet hole, ensuring the normal operation of the drying function and improving the practicality and reliability of the suitcase.

[0021] Furthermore, the suitcase body is positioned upright with its wheels touching the ground. The hairdryer bracket is installed in the lower half of the suitcase body, allowing hot air from the hairdryer to enter from the bottom of the suitcase and diffuse upwards more evenly. This ensures that clothes and other items inside the suitcase are heated more evenly, improving drying efficiency and ensuring that clothes are dried quickly and evenly. In addition, when in use, the contact force between the bottom of the hairdryer and the ground provides stable support. The cooperation of the suitcase, hairdryer bracket, and hairdryer with ground support allows users to free their hands, improving convenience and comfort.

[0022] Compared with existing technologies, the beneficial effects of this utility model are as follows: By using the base as a support frame, it provides stable support for the hair dryer, ensuring its safe installation, and also serves as a connection point to prevent loosening and detachment. The air inlet ensures smooth airflow into the air duct. The tapered design of the tapered sleeve optimizes airflow, guiding and concentrating air to form a stable airflow, increasing airflow speed and force from the wide end to the narrow end, and improving drying efficiency. The telescopic structure can retract to its shortest state when not in use, reducing space occupation. The stepped telescopic structure provides multi-level support, making the connection between the sleeve and the base stable and reducing shaking and deformation. The multi-level annular structure consists of a narrow-end support ring, a wide-end support ring, and multi-level transition support rings. The narrow-end support ring is embedded in the air inlet of the base, providing precise positioning and allowing smooth airflow into the trunk. The flexible design of the transition support rings allows the narrow-end and wide-end support rings to have relative offset freedom, adjusting the air duct orientation, dispersing stress, and reducing the risk of deformation and damage. The base consists of an inner support, an outer support, and fasteners. Through clamping and fastening, it can withstand the vibrations and external forces generated during the operation of the blower, ensuring overall stability. The sidewalls of the air inlet on the inner or outer support are reinforced with structural strength to guide and constrain airflow, preventing leakage. When the conical sleeve is not in use, the recessed cavity and openable cover of the outer support can retract into the cavity, maintaining a clean appearance and preventing dust and impact damage.

[0023] When the hairdryer bracket is integrated into the suitcase, it is mounted on the main body of the suitcase, with the air inlet connecting to the inner cavity of the suitcase body. The base is fixed to the shell, and the conical sleeve extends outward from the main body of the suitcase. The sidewall of the air inlet of the inner or outer bracket extends through the shell, ensuring smooth airflow into the suitcase. The suitcase has a flexible inner lining with an internal air inlet that aligns with the main air inlet, allowing hot air to enter the suitcase interior without obstruction. Installing the hairdryer bracket on the lower half of the suitcase body allows hot air to enter from the bottom and diffuse upwards more evenly, ensuring uniform heating of clothes and other items and improving drying efficiency. Simultaneously, the contact force between the bottom of the hairdryer and the ground provides stable support during use, forming a stable support structure with the suitcase, hairdryer, and ground, further ensuring stability during use.
