Description

Technical Field

[0001] This utility model relates to the field of hair dryer technology, and in particular to a hair dryer with temperature control via a knob. Background Technology

[0002] The main components of a hair dryer are a heating element and a high-speed fan. The principle behind its ability to dry hair is that the fan blows the heated air from the heating element onto the hair, causing the rapidly flowing hot air to quickly remove the moisture from the hair's surface. To guide the hot air and ensure that it reaches the hair effectively, a nozzle is usually also installed on the hair dryer.

[0003] A hair dryer with a convenient replaceable nozzle, disclosed in Chinese Patent CN219108891U, includes a hair dryer body with a power cord installed at its lower end and a plug at the end of the power cord. A bracket is fixedly installed on the outer side wall of the hair dryer body. A nozzle body is movably connected to the inner side wall of the upper end of the hair dryer body, and limit frames are symmetrically fixed on the outer side wall of the end of the nozzle body. A retainer is fixedly installed on the outer side wall of the upper end of the hair dryer body near the nozzle body. A positioning post is fixedly connected to the surface of the hair dryer body on the side of the retainer, and a buckle is movably installed at the upper end of the positioning post. A positioning frame is fixedly provided on the surface of the hair dryer body on the side of the positioning post.

[0004] When using the existing hair dryer, pressing the end of the clip near the support rod moves it toward the hair dryer body, causing the clip to disengage from the limiting frame. Then, the sleeve slides along the positioning frame to compress the spring, after which the hair dryer body can be removed from the hair dryer body. The process of replacing the hair dryer body is cumbersome and inconvenient for quick replacement.

[0005] To address the aforementioned problems, this utility model proposes a hair dryer with temperature control via a knob. Utility Model Content

The handle is fixedly installed on the bottom side of the body, and a first knob and a second knob are rotatably installed on the outer wall of the handle. An air inlet cover is fixedly connected to one end of the body near the handle. An air outlet is inserted into the other end of the body away from the handle. Multiple limiting grooves are evenly distributed along the axis of the body inside. Each limiting groove has a locking block slidably installed inside it. A sliding groove is provided on the outer side of the air outlet corresponding to the locking block, and the sliding groove and the locking block slide together. A slot is provided on the side of the sliding groove away from the handle, and the slot and the locking block are inserted together.

[0008] Preferably, a spring is fixedly connected to the bottom of the limiting groove, and the other end of the spring is fixedly connected to the locking block.

[0009] Preferably, the end of the card block that mates with the card slot is hemispherical.

[0010] Preferably, a fixing plate is fixedly installed inside the machine body on the side near the air inlet cover, and a fan is fixedly installed on the fixing plate.

[0011] Preferably, a heating wire is fixedly installed in the middle section of the internal part of the machine body.

[0012] Preferably, the first knob is electrically connected to the fan via a built-in circuit, and the second knob is electrically connected to the heating wire via a built-in circuit.

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a hair dryer with temperature control via a knob, comprising a handle 1 and a body 2. The handle 1 is fixedly installed on the bottom side of the body 2, and a first knob 5 and a second knob 6 are rotatably mounted on the outer wall of the handle 1. An air inlet cover 3 is fixedly connected to one end of the body 2 near the handle 1. An air outlet 4 is inserted into the other end of the body 2 away from the handle 1, and multiple limiting grooves 11 are evenly distributed along the axis of the body 2 inside.

[0025] The limiting groove 11 is equipped with a locking block 12 for limiting sliding.

[0026] A spring 10 is fixedly connected to the bottom of the inner side of the limiting groove 11, and the other end of the spring 10 is fixedly connected to the locking block 12.

[0027] On the outer side of the air outlet 4, corresponding to the position of the locking block 12, a sliding groove 14 is provided, and the sliding groove 14 slides with the locking block 12. On the side of the sliding groove 14 away from the handle 1, a locking slot 13 is provided, and the locking slot 13 inserts with the locking block 12.

[0028] The end of the card block 12 that mates with the card slot 13 is hemispherical.

[0029] Inside the main body 2, near the air inlet cover 3, a mounting plate 8 is fixedly installed, and a fan 7 is fixedly installed on the mounting plate 8. The first knob 5 is electrically connected to the fan 7 through an internal circuit. The specific structure of the internal circuit is a common existing control circuit, which will not be described in detail here.

[0030] A heating wire 9 is fixedly installed in the middle section of the internal structure 2. The second knob 6 is electrically connected to the heating wire 9 through an internal circuit. The specific structure of the internal circuit is a common existing control circuit, which will not be described in detail here.

[0031] Working principle:

[0032] When using a hair dryer, turn the first knob 5 and the second knob 6 clockwise to power on the fan 7 and the heating wire 9. After power is on, the fan 7 starts to rotate and the heating wire 9 starts to heat. The greater the rotation angle, the faster the fan 7 rotates and the higher the temperature of the heating wire 9. The speed of the fan 7 can be controlled by rotating the first knob 5, and the temperature of the heating wire 9 can be controlled by rotating the second knob 6, thus controlling the speed and temperature of the blown air.

[0033] When you need to change the air outlet 4 according to your hairstyle, hold the main body 2 with one hand and the air outlet 4 with the other hand, and pull out the air outlet 4.

[0034] In the initial state, the spring 10 is compressed. When pulled out, the locking block 12 slides out from the slot 13 and slides towards the spring 10 in the limiting groove 11, compressing the spring 10. When the air outlet 4 is pulled out, the locking block 12 slides in the surface of the slide groove 14. When replacing with another type of air outlet 4, insert the air outlet 4 into the body 2.

[0035] The sliding groove 14 on the air outlet 4 will first press the locking block 12 into the limiting groove 11. When the locking groove 13 is inserted into the position of the locking block 12, the spring 10 will push the locking block 12 into the locking groove 13. At this time, the spring 10 is in a compressed state and will lock the air outlet 4. Thus, the installation of the air outlet 4 is completed.

[0036] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
