Description

Technical Field

[0001] This utility model relates to the field of hair dryer technology, specifically to a hair dryer with a stable magnetic nozzle. Background Technology

[0002] A hair dryer consists of a body and a nozzle. A magnet is installed at the front of the body, and the nozzle is magnetically attached to the front of the body. If the magnet's magnetic force is not strong enough, it cannot securely hold the nozzle, and the nozzle may easily fall off during use. Some hair dryers increase the number of magnets to enhance the magnetic force; however, because magnets themselves generate dispersed magnetic lines of force that can interfere with nearby electronic devices, increasing the number of magnets can lead to increased magnetic interference from the hair dryer to nearby electronic equipment. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a hair dryer with a stable magnetic nozzle, which can enhance the magnetic attraction of the nozzle and have less magnetic interference to nearby electronic devices.

[0004] To solve the above-mentioned technical problems, the hair dryer with a stable magnetic nozzle of this utility model has a magnet at the front end for magnetic suction of the nozzle, and a magnetic guide block behind the magnet to enhance the magnetic attraction force at the front end of the magnet.

[0005] Furthermore, the magnetic guide block is installed on the body of the hair dryer, and the magnet is installed on the magnetic guide block.

[0006] Furthermore, the magnet is specifically a ring-shaped magnet, and the magnetic conductive block is correspondingly a ring-shaped magnetic conductive block, coaxial with the magnet.

[0007] Furthermore, the magnetic block is positioned behind the magnet to provide axial positioning.

[0008] Furthermore, the magnet is specifically composed of multiple arc-shaped magnet blocks forming a ring.

[0009] Furthermore, a gap is left between each pair of adjacent arc-shaped magnet blocks.

[0010] Furthermore, the magnetic guide block has a notch for aligning with the gap; the blower body is provided with a circumferential positioning part, which is inserted forward into the notch and gap to circumferentially position the magnetic guide block and the magnet.

[0011] Furthermore, the outer edge of the magnetic block extends forward to form a positioning ring that blocks the magnet from the outside and positions it radially.

[0012] Furthermore, the magnetically conductive block is specifically a metal magnetically conductive block.

[0013] Furthermore, the nozzle is magnetically attached to the front of the hair dryer body by a magnet; a protective cover is provided in front of the magnet, which is placed between the nozzle and the magnet to protect the magnet.

[0014] This invention utilizes magnetic conductive technology, placing a magnetically conductive block behind the magnet. The block enhances the magnetic attraction at the front end of the magnet, thus enabling the magnet to firmly hold the air nozzle. This strengthens the magnetic attraction to the nozzle without increasing the number of magnets. Since the magnetically conductive block itself does not generate magnetic lines of force, its placement behind the magnet minimizes magnetic interference to nearby electronic equipment.

[0020] The present invention will be further described in detail below with reference to specific embodiments.

[0021] Hair dryer Figure 1 and Figure 3 It includes a body 1 and a nozzle 9. A magnet 2 is located at the front end of the body 1, and the nozzle 9 is magnetically attached to the front end of the body 1 by the magnet 2. See body 1. Figure 5 The front end of the device is fitted with a ring-shaped iron mounting bracket 3. The mounting bracket 3 has four arc-shaped mounting parts 31 arranged circumferentially, with a gap 30 between each two adjacent mounting parts 31. The magnet 2 is a ring-shaped magnet, coaxial with the mounting bracket 3, and consists of four arc-shaped magnet blocks 21. The four arc-shaped magnet blocks 21 are magnetically attached to the front side of the four arc-shaped mounting parts 31 from front to back, with a gap 20 between each two adjacent arc-shaped magnet blocks 21 to align with the gap 30. See Figure 4 and Figure 5The outer edge of the mounting bracket 3 extends forward to form a positioning ring 36, which blocks the outer side of the annular magnet 2 for radial positioning. A coaxial annular iron protective cover 4 covers the front end 26 of the annular magnet 2, positioned between the nozzle 9 and the magnet 2 to protect it. The protective cover 4 has a positioning opening 40 that aligns rearward with the gap 20. The body 1 has a circumferential positioning part 11 protruding outward, which engages forward with the notch 30, the gap 20, and the positioning opening 40 to circumferentially position the mounting bracket 3, the magnet 2, and the protective cover 4. See [link to product details]. Figure 3 and Figure 4 The machine body 1 has a rear positioning part 15 behind the mounting bracket 3. The outer side of the machine body 1 is covered by a shell 5. The rear end 59 of the shell 5 is fastened to the rear end 19 of the machine body 1. The front end of the shell 5 has a front positioning part 55, located in front of the protective cover 4. The front and rear positioning parts 55 and 15 clamp the mounting bracket 3, magnet 2 and protective cover 4 one in front and one behind, thereby axially positioning the mounting bracket 3, magnet 2 and protective cover 4. The outer edge of the protective cover 4 has a protruding positioning block 45 (see Figure 5 It is located inside the front end of housing 5, contacts the inner wall of the front end of housing 5, and radially positions the front end of housing 5. See Figure 2 and Figure 4 A gap is left between the front positioning part 55 of the housing 5 and the front end of the body 1 to form a forward-facing annular mounting groove 13. The mounting bracket 3, magnet 2, and protective cover 4 are located at the bottom of the mounting groove 13 and are coaxial with the mounting groove 13. The nozzle body 91 is made of plastic, and an iron ring 92 is installed at its rear end. The iron ring 92 extends backward from the nozzle body 91 and is inserted into the mounting groove 13 and attracted by the magnet 4. The nozzle 9 is installed at the front end of the body 1 in this way.

[0022] The applicant used four arc-shaped neodymium iron boron magnet blocks 21 with an inner diameter of 36.4 mm, an outer diameter of 41.4 mm, and a thickness of 3 mm to assemble a ring magnet 2 for experimentation. First, the Gauss value of the front end of each of the four arc-shaped neodymium iron boron magnet blocks 21 was measured. Then, under the same conditions, the four arc-shaped neodymium iron boron magnet blocks 21 were installed on the front side of the four arc-shaped mounting parts 31 of the iron mounting frame 3, and the Gauss value of the front end of each of the four arc-shaped neodymium iron boron magnet blocks 21 was measured again. The experimental data are as follows:

[0023]

[0024] The experimental data above shows that placing an iron mounting bracket 3 behind magnet 2 can enhance the Gaussian value (GS) at the front end of magnet 2, that is, enhance the magnetic force at the front end of magnet 2. Therefore, it can be concluded that... Figure 4The iron mounting bracket 3 acts as a magnetic guide block, guiding the magnetic lines of force behind the magnet 2 and enhancing the magnetic attraction of the front end 26 of the annular magnet 2. This allows the magnet 2 to firmly hold the magnetic nozzle 9, thus increasing the magnetic attraction to the nozzle 9 without increasing the number of magnets. Since the mounting bracket 3 itself does not generate magnetic lines of force, its placement behind the magnet 2 minimizes magnetic interference to nearby electronic equipment.

[0025] Common sense dictates that, under the same impact force, a complete circular ring is more likely to break than a curved object. Therefore, the magnet 2 in this hair dryer does not use a complete circular ring magnet, but rather... Figure 5 The device consists of a ring formed by four arc-shaped magnet blocks 21. This design prevents the four arc-shaped magnet blocks 21 from easily breaking if the front end of the hair dryer accidentally hits another object. The gap 20 between each pair of adjacent arc-shaped magnet blocks 21 serves both as a positioning gap, allowing the circumferential positioning part 11 of the body 1 to engage for circumferential positioning, and as a disassembly gap, facilitating the removal of the arc-shaped magnet blocks 21. Specifically, one end of the arc-shaped magnet block 21 can swing towards the center through the gap 20, detaching from the arc-shaped mounting part 31 and then being disassembled forward from the mounting bracket 3.

[0026] In this embodiment, the mounting bracket 3 is made of iron. Other embodiments may use other materials, such as a nickel-containing metal or other materials that can enhance the magnetic force of the front end 26 of the magnet 2.

[0027] In this embodiment, the protective cover 4 is made of iron. In other embodiments, the protective cover 4 can be made of other materials, such as plastic or copper.

[0028] The above description is merely an embodiment of the present invention and does not limit the scope of patent protection. Any non-substantial changes or substitutions made by those skilled in the art based on the present invention will still fall within the scope of patent protection.
