Description

Technical Field

[0001] This application relates to the field of electrical technology, and in particular to a nozzle device. Background Technology

[0002] Hair dryers, as household appliances, are widely used for styling hair, drying clothes, and other tasks. When using a hair dryer, the air outlet comes into direct contact with clothing or skin, resulting in high heat efficiency and a good drying effect. However, if the distance between the hair dryer's outlet and the object being dried is too close, overheating can cause clothing to fade, age prematurely, and other quality issues. Furthermore, when applied to the human body, it can easily cause burns.

[0003] In addition, when a hair dryer comes into contact with the surface of an object to be dried, the object can easily block the air outlet of the hair dryer, causing it to overheat and damage the hair dryer. Hair dryers with overheat protection will shut down due to overheating, affecting their use.

[0004] Therefore, based on the above problems, existing technologies need to be improved. Utility Model Content

[0005] The purpose of this application is to ensure that the first air outlet can still output air from the hair dryer even when the second air outlet is blocked, thus preventing the hair dryer from overheating and shutting down, and improving the safety and convenience of use.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution: a nozzle device, including a housing, the housing being detachably installed at the air outlet of a blower, the housing forming a receiving cavity, the housing having an air inlet connected to the receiving cavity, the housing having a plurality of first air outlet holes located away from the air inlet, the housing having a plurality of abutting members, the abutting members being hollow and having an air outlet channel, one end of the air outlet channel being connected to the receiving cavity, and the other end of the air outlet channel located away from the receiving cavity being a second air outlet hole.

[0007] By adopting the above technical solution and setting a first air outlet and a second air outlet, even if the second air outlet is blocked, the first air outlet can still guarantee airflow, avoiding overheating and shutdown issues caused by air outlet blockage, thus improving the safety and stability of the hair dryer. The design of the air inlet, receiving cavity, and multiple air outlets and channels ensures more even airflow, providing users with a more stable and comfortable blowing experience. The detachable shell design allows users to easily replace or adjust the nozzle device according to different needs, increasing the hair dryer's applicability in various scenarios.

[0008] Optionally, the end of the abutment near the second air outlet is curved.

[0009] By adopting the above technical solutions, the curved surface design can better conform to the surfaces of objects of various shapes and materials. Whether it is a flat or curved surface, it can ensure effective airflow and expand the application range of the nozzle device. The curved surface is smoother when in contact with objects, reducing pressure and friction on the contacting objects and making it more comfortable to use.

[0010] Optionally, the receiving cavity is provided with an air filter screen, which is located at the air inlet.

[0011] By adopting the above technical solution, the air filter can distribute the incoming air more evenly within the receiving cavity, thereby ensuring a more stable and uniform airflow from each outlet. It can effectively filter out impurities such as dust and hair that may be present in the air, improving the cleanliness of the blown air. It also prevents larger foreign objects from entering the receiving cavity and damaging the internal air ducts and other structures.

[0012] Optionally, the air inlet is provided with a plurality of guide vanes, the guide vanes are connected to a first mounting component, the first mounting component is provided with a mounting post, the air filter is provided with mounting holes, and the air filter is fitted onto the mounting post through the mounting holes.

[0013] By adopting the above technical solution, several guide vanes can guide the air into the receiving cavity in a more reasonable direction and speed, reducing wind resistance and improving air intake efficiency. The cooperation of the mounting column and mounting holes makes the installation and removal of the filter screen simple and quick, facilitating users to clean, maintain, or replace the filter screen and ensuring its filtration effect. The design of the first mounting component and mounting column provides a stable support for the guide vanes and filter screen, ensuring that the components will not loosen or shift during use, guaranteeing the normal operation of the air nozzle device.

[0014] Optionally, the outer casing includes a first casing, a second casing, and a third casing. The first mounting member is disposed on the first casing via the guide vane. The second casing is provided with a second mounting member. The second mounting member has a recessed fitting groove. The mounting post can fit into the fitting groove, so that the second casing is mounted on the first casing.

[0015] By adopting the above technical solution, the outer casing is divided into a first casing, a second casing, and a third casing, simplifying the structure of each casing, reducing production difficulty and cost, and improving production efficiency. If a casing or component is damaged, only the corresponding part needs to be replaced, instead of replacing the entire casing, saving maintenance costs. The mating groove and mounting post allow the second casing to be quickly and accurately installed on the first casing, simplifying the assembly process and improving overall assembly efficiency. This mating installation method provides good connection strength, ensuring that the various parts of the casing will not loosen or separate during use, guaranteeing the normal operation of the nozzle device.

[0016] Optionally, the third housing is fitted onto the first housing, the second housing is provided with a first snap-fit ​​component, and the third housing is provided with a second snap-fit ​​component. The first snap-fit ​​component engages with the second snap-fit ​​component to mount the second housing onto the third housing.

[0017] By adopting the above technical solution, the cooperation between the first and second snap-fit ​​components provides a secure connection, ensuring that the second and third housings will not easily separate during use, thus enhancing the overall structural stability of the nozzle assembly. The snap-fit ​​method is simple and quick to operate, requiring no complex tools or steps, greatly improving assembly efficiency and reducing assembly costs. When maintenance or cleaning of the nozzle assembly's interior is required, the second and third housings can be easily disassembled by releasing the snap-fit, facilitating operation. A good snap-fit ​​reduces gaps between the housings, improving the nozzle assembly's sealing performance and ensuring effective and efficient airflow.

[0018] Optionally, the housing is recessed with a mounting groove, and an adsorption element is provided in the mounting groove for adsorbing at the air outlet of the hair dryer.

[0019] By adopting the above technical solution, the suction component allows the nozzle device to be quickly and easily attached to the air outlet of the hair dryer, eliminating the need for complicated installation steps and saving users time and effort. The suction component provides strong adhesion, ensuring the nozzle device will not easily fall off or shift during use, guaranteeing the stability and safety of the airflow. The recessed mounting groove prevents the suction component from protruding from the outer casing surface, maintaining the nozzle device's flat and aesthetically pleasing appearance. This suction-type installation method is suitable for various models and sizes of hair dryer outlets, increasing the versatility and applicability of the nozzle device.

[0020] Optionally, the adsorption element is a magnet.

[0021] By employing the above technical solution, the magnet provides strong and durable magnetic attraction, ensuring that the nozzle device remains firmly fixed to the air outlet even when the hair dryer is in operation, preventing it from easily falling off. Magnets are common and relatively inexpensive materials, and using them as the adsorption component reduces the overall cost of the nozzle device. Magnets possess good durability and stability, making them less susceptible to damage from prolonged use or external factors, thus extending the lifespan of the nozzle device. Compared to some fixing methods that may scratch or damage the hair dryer's air outlet, magnetic adsorption does not cause any damage to the hair dryer.

[0022] In summary, this application has at least the following beneficial effect:

[0023] 1. The design of the first and second air outlets arranged in layers ensures that even if the second air outlet is blocked during use, the first air outlet can continue to work, thus avoiding the problem of the hair dryer overheating and shutting down.

[0024] 2. The design of the air filter and guide vanes ensures uniform airflow and improves the blowing effect.

[0025] 3. The magnetic adsorption connection method makes the installation and removal of the nozzle device simple and easy, greatly improving the user's convenience. Attached Figure Description

[0033] The present application will be further described in detail below with reference to the accompanying drawings.

[0034] In this embodiment, refer to Figure 1-5A nozzle device includes a housing 1 detachably mounted to the air outlet of a hair dryer. The housing 1 contains a receiving cavity 2 and an air inlet 3 to ensure smooth airflow into the cavity 2. Several first air outlets 4 are designed on the housing 1 away from the air inlet 3, ensuring initial air dissipation. To enhance airflow adaptability, the housing 1 also features abutment members 5, which are hollow, forming air outlet channels 6. One end of these channels connects to the receiving cavity 2, and the other end serves as a second air outlet 7. In practical use, the abutment members 5 directly contact the items to be dried, enhancing the heating effect and improving drying efficiency. Furthermore, even when the second air outlet 7 is blocked, the first air outlets 4 maintain a certain distance from the items, ensuring smooth airflow from the hair dryer. This design effectively prevents the hair dryer from overheating and shutting down due to blocked air outlets.

[0035] The implementation principle of Example 1 is as follows: the air generated by the hair dryer enters the receiving cavity 2 through the air inlet 3, and is then evenly dispersed by the air filter 8, and discharged from the first air outlet 4 and the second air outlet 7 respectively. When the nozzle device is close to the surface of the object to be dried, even if the second air outlet 7 is partially or completely blocked, the first air outlet 4 can still continue to output air, thereby avoiding overheating of the hair dryer.

[0036] Example 2

[0037] The difference between this embodiment and Embodiment 1 is that, referring to... Figure 1 The end of the contact piece 5 near the second air outlet 7 is designed with a curved surface. This design can better adapt to contact surfaces of different shapes, such as clothing or skin, ensuring smooth airflow from the first air outlet 4 and the second air outlet 7, and improving user comfort.

[0038] Example 3

[0039] Based on Example 2, referring to Figure 3 and Figure 4 In this embodiment, a filter screen 8 is further added inside the receiving cavity 2, and the filter screen 8 is arranged at the air inlet 3. The filter screen 8 not only helps to evenly distribute the incoming air, but also filters out impurities in the air to a certain extent, improving the quality of the air.

[0040] Example 4

[0041] The difference between this embodiment and embodiment 3 is that, referring to 3 and... Figure 4Several guide vanes 9 are added to the air inlet 3, and each guide vane 9 is connected to a first mounting component 10. The first mounting component 10 is connected to the outer casing 1 through the guide vanes 9. The design of the guide vanes 9 can further optimize the air intake path, reduce wind resistance, and improve air intake efficiency. At the same time, the mounting post 11 provided on the first mounting component 10 allows the air filter 8 to be quickly and securely fitted onto the mounting post 11 through the mounting holes 12, thereby simplifying the installation and replacement process of the air filter 8.

[0042] Example 5

[0043] Based on Example 4, referring to Figure 3 In this embodiment, the structure of the outer shell 1 is further subdivided and optimized. Specifically, the outer shell 1 is divided into three parts: a first shell 101, a second shell 102, and a third shell 103. The first mounting member 10 is mounted on the first shell 101 via guide vanes 9. The second shell 102 is provided with a second mounting member 13, which has an internal fitting groove 14 that can engage with the mounting post 11 on the first mounting member 10, thereby achieving a stable connection between the second shell 102 and the first shell 101. Furthermore, the third shell 103 is designed to fit over the first shell 101, protecting it, and is securely connected to the second shell 102 through the cooperation of a first snap-fit ​​member 15 and a second snap-fit ​​member 16. This split design not only facilitates the production and assembly of the device but also improves the overall stability and service life of the device.

[0044] Example 6

[0045] This embodiment is based on embodiment 5, and refers to... Figure 2 and Figure 5 Furthermore, a mounting groove 17 and an adsorption element 18 are added to the outer casing 1. Specifically, the mounting groove 17 is designed to be concave and located at an appropriate position on the outer casing 1 to accommodate the adsorption element 18. The adsorption element 18 is a magnet, which uses its magnetism to achieve a quick adsorption connection with the air outlet of the hair dryer. This connection method is not only simple and convenient, but also greatly improves the installation stability and ease of use of the device. In other embodiments, the outer casing 1 can be directly nested and installed at the air outlet of the hair dryer, or the outer casing 1 can be directly screwed onto the air outlet of the hair dryer by providing a threaded structure on the outer casing 1. At the same time, the outer casing 1 and the air outlet of the hair dryer can be fixed by bolts or other fasteners.

[0046] Example 7

[0047] Building upon Example 6, to further adapt to the needs of different users, users can adjust the aperture of the air vents on the filter screen 8, the aperture of the first air outlet 4, and the aperture of the second air outlet 7 according to actual requirements, thereby controlling the intensity and range of the airflow. This improves the applicability and flexibility of the device and allows users to make personalized adjustments and optimizations based on specific usage scenarios.

[0048] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
