Description

Technical Field

[0001] This utility model relates to the field of hair dryer technology, and in particular to a portable hair dryer accessory. Background Technology

[0002] Hair dryers are generally divided into household hair dryers and industrial hair dryers depending on their application. Household hair dryers typically have lower airflow, while industrial hair dryers have relatively higher airflow, often referred to as "powerful" hair dryers. Generally, the nozzle of a powerful hair dryer is much longer than that of a household hair dryer. In terms of structural design, considering packaging and transportation costs, the nozzle and main unit are usually designed as a detachable structure, minimizing the overall size of the device during packaging to save costs. When the user opens the packaging, the nozzle and main unit are separate. During use, they are secured together by a fitting between the nozzle and the end of the main unit. In actual use, few people keep the packaging box for long. For later storage and transport, either the nozzle is kept attached to the main unit to prevent loss, but this results in a larger overall size, or the nozzle is left scattered beside the main unit, saving space but making it easy to lose. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a portable hair dryer accessory that allows the air delivery tube to remain detachably connected to the main unit when not in use, preventing loss, while maintaining a compact overall size for easy storage and carrying.

[0004] The technical solution to achieve the purpose of this utility model is:

[0005] A portable hair dryer accessory includes a main unit and a blower tube. The axial end face of the blower tube is detachably mounted on the air outlet of the main unit. The side wall of the main unit is provided with a first connector, and the side wall of the blower tube is provided with a second connector adapted to the first connector. The blower tube is connected to the main unit through the cooperation of the second connector and the first connector, so that it can be detachably mounted on the main unit when not in operation.

[0006] Furthermore, the bottom of the main unit is provided with a handle, and the air supply tube is arranged parallel to the air supply direction of the main unit and located above the handle when not in operation.

[0007] Furthermore, the length of the air supply duct is not greater than the length of the main unit, and in the non-working state, no end face of the air supply duct protrudes beyond the length direction end face of the main unit.

[0008] Furthermore, when the air supply duct is not in operation, the end face of the air outlet near the main unit is flush with the air outlet of the main unit.

[0009] Furthermore, the first connector includes two opposing limiting seats integrally formed with the main unit, and a slot is formed between the two limiting seats. The second connector is integrally formed with the air supply tube and is provided with a locking block adapted to the slot. The air supply tube is locked into the slot by the locking block and is detachably fixed to the main unit.

[0010] Furthermore, the slot has a T-shaped cross-section and a locking groove is provided at the opening extending parallel to the fan axis. The block has an I-shaped cross-section and a locking pin that matches the locking groove is provided in the side notch. When the side wall of the air duct is fixedly connected to the side wall of the main unit, the locking pin is engaged in the locking groove.

[0011] Furthermore, one end of the card slot along the axial direction is a free end, and the other end is provided with a limiting platform. The card block is provided with a limiting baffle at one end corresponding to the free end of the card slot, and the other end is a free end.

[0012] Furthermore, the card block has a groove on the side near the air supply duct, and reinforcing ribs integrally formed with the card block are provided in the groove and on the side of the locking pin.

[0013] Furthermore, the rear end of the card block along the insertion slot direction is larger than the front end.

[0014] Furthermore, the inner wall of the card slot is provided with a first protruding ridge on the upper and lower sides, and the card block is provided with a symmetrical inclined surface on the side near the main unit. The two inclined surfaces are smoothly transitioned to form a second protruding ridge parallel to the axial direction of the air supply tube. When the card block is inserted into the card slot, the first protruding ridge contacts the card block, and the second protruding ridge contacts the card slot.

[0015] By adopting the above technical solution, this utility model has the following beneficial effects:

[0016] (1) By adding a first connector and a second connector, the present invention enables the air supply tube to be detachably connected to the side of the main unit by the cooperation of the two connectors when it is disassembled from the air outlet of the main unit after use, forming a whole. This solves the risk of the air supply tube being easily lost. At the same time, compared with the state when the air supply tube is installed at the air outlet, the overall size is small and easy to store and carry.

[0017] (2) This utility model limits the direction and height of the air supply tube when it is not in operation, so as to avoid the air supply tube interfering with the operator's grip on the main unit.

[0018] (3) When designing the detachable parts of the air duct and the main unit along the air supply channel axis, the length of the air duct is designed to be no greater than the length of the main unit, so that the air duct will not protrude from the main unit when it is installed on the side wall of the main unit, thus minimizing the overall length dimension.

[0019] (4) This utility model designs the end face of the air supply tube to be flush with the air outlet of the main unit, which facilitates the protection design of the two end faces during packaging design.

[0020] (5) The first and second connecting parts of this utility model adopt matching card blocks and card slots, which are simple in structure and easy to disassemble and assemble.

[0021] (6) This utility model achieves sliding mounting by setting a T-shaped slot and an I-shaped block, which further simplifies the assembly and disassembly steps. At the same time, it sets a locking groove and a locking pin that cooperate with each other to improve the connection strength of the two connecting parts.

[0022] (7) By setting a limiting platform and a limiting baffle, this utility model limits the depth of the card block into the card slot, so as to avoid excessive force during installation, which would cause the locking pin to misalign with the locking slot and cause locking failure.

[0023] (8) By setting grooves, this utility model saves material costs and adds reinforcing ribs to improve the overall structural strength and avoid deformation failure.

[0024] (9) The size of one end of the card block of this utility model is larger than that of the other end, which makes it easier to insert into the card slot.

[0025] (10) By setting the first convex ridge and the second convex ridge, the contact area is reduced during the insertion of the card block into the card slot, thereby reducing frictional resistance and making disassembly and assembly easier. Attached Figure Description

Detailed Implementation

[0035] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0036] (Example)

[0037] like Figures 1 to 6 The portable hair dryer shown includes a main unit 1 and an air delivery tube 2. The axial end face of the air delivery tube 2 is detachably mounted on the air outlet of the main unit 1 using a conventional rotating clip. This allows the air delivery tube 2 to be installed on the air outlet during use and detached when not in use, reducing the overall size and facilitating storage. The side wall of the main unit 1 has a first connecting piece 3, and the side wall of the air delivery tube 2 has a second connecting piece 4 that matches the first connecting piece 3. The air delivery tube 2 is connected to the first connecting piece 3 through the cooperation of the second connecting piece 4, so that the air delivery tube 2 can be detachably mounted on the main unit 1 when not in use, forming a whole. This solves the risk of the air delivery tube 2 being easily lost when detached from the air outlet, and compared to the state when the air delivery tube is installed on the air outlet, the overall size is compact, making it easy to store and carry.

[0038] Specifically, the bottom of the main unit 1 is provided with a handle 1-1. When not in operation, the air supply duct 2 is positioned parallel to the air supply direction of the main unit 1 and above the handle 1-1, preventing the air supply duct 2 from interfering with the operator's grip on the handle 1-1. The length of the air supply duct 2 is less than the length of the main unit 1, and when not in operation, no end face of the air supply duct 2 protrudes beyond the length direction end face of the main unit 1, minimizing the overall structural length dimension. In this embodiment, the end face of the air supply duct 2 near the air outlet of the main unit 1 is flush with the air outlet of the main unit 1, facilitating protective design of both end faces during packaging design.

[0039] The first connector 3 includes two opposing limiting seats 3-1 integrally formed with the main unit 1, forming a slot between the two limiting seats 3-1. The second connector 4 is integrally formed with the air supply duct 2 and is provided with a locking block 4-1 adapted to the slot. The air supply duct 2 is inserted into the slot through the locking block 4-1 and is detachably fixed to the main unit. The structure is simple and easy to disassemble and assemble.

[0040] To further facilitate assembly and disassembly, this embodiment designs the slot with a T-shaped cross-section and the block 4-1 with an I-shaped cross-section, achieving connection through interlocking. Furthermore, the rear end of the block 4-1 along the insertion direction of the slot is larger than the front end, further facilitating insertion of the block 4-1 into the slot. The limiting seat 3-1 has an arc-shaped notch, forming a locking groove 3-2 at the opening of the slot extending parallel to the axial direction of the fan 1. A locking pin 4-2, compatible with the locking groove 3-2, is provided in the side notch of the block 4-1. When the side wall of the air duct 2 is fixedly connected to the side wall of the main unit 1, the locking pin 4-2 engages in the locking groove 3-2, increasing the connection strength of the two connecting parts. The left end of the slot is a free end, and the right end is equipped with a limiting platform 3-3. The left end of the card block 4-1 is equipped with a limiting baffle 4-3, and the right end is a free end. By setting the limiting platform 3-3 and the limiting baffle 4-3, the depth of the card block 4-1 inserted into the slot is limited, so as to avoid excessive force during installation, which would cause the locking pin 4-2 to misalign with the locking groove 3-2 and cause locking failure.

[0041] The locking block 4-1 has a groove on the side near the air supply duct 2, which saves material costs. The groove and the side of the locking pin 3-2 are both provided with reinforcing ribs 4-4 integrally formed with the locking block 4-1, which improves the overall structural strength and prevents deformation and failure.

[0042] Considering the large contact area of ​​the card block 4-1 during insertion into the card slot, this embodiment provides first protruding ridges 3-4 on both the upper and lower sides of the inner wall of the card slot. Simultaneously, the side of the card block 4-1 closest to the main unit 1 has symmetrically arranged inclined surfaces, with a smooth transition between the two inclined surfaces forming a second protruding ridge 4-5 parallel to the axial direction of the air supply duct 2. When the card block 4-1 is inserted into the card slot, the first protruding ridge 3-4 contacts the card block 4-1, and the second protruding ridge 4-5 contacts the card slot, reducing the contact area and thus reducing frictional resistance, making assembly and disassembly easier.

[0043] This invention, by adding a first connecting member 3 and a second connecting member 4, allows the air supply duct 2 to be detachably connected to the side of the main unit 1 after use by the cooperation of the two connecting members, forming a whole. This solves the risk of the air supply duct being easily lost, and compared to when the air supply duct is installed at the air outlet, the overall size is compact, making it easy to store and carry. The two connecting members use a sliding interlocking method, which is simple in structure and easy to assemble and disassemble. They are also equipped with locking grooves and locking pins that lock together to ensure sufficient connection strength and prevent detachment.

[0044] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
