Description

Technical Field

[0001] This utility model relates to the technical field of household appliances, specifically to a hair dryer. Background Technology

[0002] Hair dryers are common small appliances, and to make them more portable, there's an increasing trend towards smaller and more compact designs. Existing direct-vent hair dryers are relatively small and easy to carry. However, this smaller size limits the number of air inlets, resulting in a correspondingly limited airflow and a lower maximum airflow. This affects the drying effect and leads to a poor user experience. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, the main purpose of this utility model is to provide a hair dryer that can solve the problem that traditional hair dryers cannot guarantee a large air volume when they are small in size.

[0004] To achieve the above objectives, this utility model proposes a hair dryer, comprising:

[0012] Optionally, the electrical connection part includes a conductor wire, and the insulation part includes a wire sleeve. The wire sleeve is fitted on the inner periphery of the wire hole and covers the outer periphery of the conductor wire. At least a portion of the conductor wire can extend from the front end of the wire sleeve to connect to the inside of the hair dryer body.

[0013] The wire clamping structure has a first clamping part that clamps onto the outer periphery of the wire sleeve, and a second clamping part that clamps onto the outer periphery of the conductor exposed at the front end of the wire sleeve.

[0014] Optionally, the first snap-fit ​​portion includes a first snap ring sleeved on the outer periphery of the insulating portion, and the second snap-fit ​​portion includes a second snap ring sleeved on the outer periphery of the conductor wire. The first snap ring and the second snap ring are spaced apart along the axial direction of the wire hole and form a stop-fit ​​with the power line along the axial direction of the wire hole.

[0015] Optionally, the outer periphery of the sleeve is further provided with a snap-fit ​​groove. The first snap ring includes a first half-ring and a second half-ring connected to each other. The first half-ring and the second half-ring are both located in the snap-fit ​​groove and are respectively snapped into the snap-fit ​​groove on both sides of its radial direction.

[0016] Optionally, the second retaining ring is located outside the retaining groove and forms a stop-fit ​​with the outer wall of the retaining groove along the axial direction of the thread hole.

[0017] Optionally, a first locking protrusion protrudes from one side of the first semi-ring body along its axial direction, and a second locking protrusion protrudes from one side of the second semi-ring body along its axial direction. The first locking protrusion and the second locking protrusion are respectively engaged with the radial sides of the conductor wire to jointly enclose and form the second retaining ring.

[0018] Optionally, the first semi-ring and the second semi-ring have opposing surfaces, one of which has a positioning protrusion and the other has a positioning groove that engages with the positioning protrusion.

[0021] The technical solution provided by this utility model has the following beneficial effects:

[0022] The hair dryer provided by this utility model includes a hair dryer body, a power cord, and a cord clamping structure. An air inlet is provided on the peripheral side of the hair dryer body, allowing airflow to enter the airflow channel within the hair dryer body through the air inlet. After being heated or guided, the airflow exits from the air outlet of the hair dryer body and is blown onto the hair. The power cord is threaded through the hair dryer body, connecting a power supply device and a heating device. The heating device heats the airflow entering the hair dryer body before it is blown out through the air outlet. The cord clamping structure secures the power cord to the hair dryer body, preventing displacement and connection failure. A first through-hole is provided on the cord clamping structure, and a second through-hole is provided on the hair dryer body to connect to the outside environment and the first through-hole. External airflow passes through the second through-hole and the first through-hole to enter the airflow channel of the hair dryer body. Increasing the number of through-holes increases the airflow volume. In this invention, on the one hand, the cable-clamping structure secures the power cord, preventing it from being pulled out during use and ensuring better electrical connection stability. On the other hand, the cable-clamping structure allows for the addition of a second through-hole on the hair dryer body. Airflow can enter the airflow channel through the second through-hole and then the first through-hole, thereby increasing the air volume. Furthermore, since openings at the power cord allow external liquids to easily enter, especially at the electrical connection point, potentially causing short circuits or damage to the hair dryer, the cable-clamping structure, positioned between the electrical connection point and the second through-hole, effectively prevents external liquids from entering the hair dryer body, particularly preventing liquids from directly falling into the electrical connection point, thus better protecting the hair dryer from damage. This hair dryer, without changing its overall size, not only better protects the hair dryer but also effectively increases the air volume to meet users' needs for higher airflow.

[0037] This utility model provides a hair dryer 100. For details, please refer to [link / reference needed]. Figure 1 and Figure 2 In this embodiment, the hair dryer 100 includes a hair dryer body 1, a power cord 2, and a wire-clamping structure 3. The hair dryer body 1 has an air inlet 121 and an air outlet 111, and an airflow channel connecting the air inlet 121 and the air outlet 111. The power cord 2 has an electrical connection portion 21 and an insulation portion 22. The electrical connection portion 21 is connected to the inside of the hair dryer body 1, and at least a portion of the insulation portion 22 can pass through the hair dryer body 1. The wire-clamping structure 3 is disposed inside the hair dryer body 1 and clamped to the outer periphery of the power cord 2. The wire-clamping structure 3 has a first through hole 313 that communicates with the airflow channel, and the hair dryer body 1 has a second through hole 122 that is suitable for communicating with the outside world and the first through hole 313. At least a portion of the wire-clamping structure 3 is located between the electrical connection portion 21 and the second through hole 122 to form a barrier.

[0038] In this embodiment, an air inlet 121 is provided on the peripheral side of the hair dryer body 1. Airflow can enter the airflow channel inside the hair dryer body 1 through the air inlet 121, and after being heated or guided, it is blown towards the hair through the air outlet 111 of the hair dryer body 1. Moreover, a power cord 2 is threaded through the hair dryer body 1. The power cord 2 can be electrically connected to a power supply device and a heating device, so that the heating device heats the airflow entering the hair dryer body 1 before blowing it out through the air outlet 111. Furthermore, the power cord 2 can be fixed to the hair dryer body 1 by a wire clamping structure 3 to prevent the power cord 2 from easily shifting and causing the power cord 2 connection failure. Moreover, a first through hole 313 is provided on the wire clamping structure 3, and a second through hole 122 suitable for connecting the outside and the first through hole 313 is provided on the hair dryer body 1. External airflow can pass through the first through hole 313 through the second through hole 122 to enter the airflow channel of the hair dryer body 1. The airflow is increased by increasing the number of holes. In this invention, on the one hand, the wire-clamping structure 3 secures the power cord 2, preventing it from being pulled out during use and ensuring better electrical connection stability. On the other hand, the wire-clamping structure 3 allows for the addition of a second through-hole 122 to the hair dryer body 1, enabling airflow to enter the airflow channel through the second through-hole 122 and the first through-hole 313, thereby increasing the airflow volume. Furthermore, since the opening at the power cord 2 makes it easy for external liquids to enter, especially at the electrical connection 21, the hair dryer 100 is prone to short circuits or wiring damage. Therefore, the wire-clamping structure 3, positioned between the electrical connection 21 and the second through-hole 122 of the power cord 2, effectively prevents external liquids from entering the hair dryer body 1, particularly preventing liquids from directly falling into the electrical connection 21, thus better protecting the hair dryer 100 from damage. This hair dryer 100, without changing its overall size, not only better protects itself but also effectively increases the airflow volume to meet users' needs for higher airflow.

[0039] Specifically, regarding the hair dryer body 1, in combination with Figures 1 to 2As shown, the hair dryer body 1 includes a first housing 11 and a second housing 12 connected together, and an inner cylinder 13 disposed inside the second housing 12. Preferably, the first housing 11, the second housing 12, and the inner cylinder 13 are all generally cylindrical, and the outer diameters of the first housing 11 and the second housing 12 are the same, making the outer surface of the hair dryer 100 smoother. The inner cylinder 13 and the second housing 12 are generally coaxial. The air outlet 111 is disposed on the first housing 11, the air inlet 121 is disposed on the peripheral side of the second housing 12, the second through hole 122 is disposed on the end face of the second housing 12, and the wire clamping structure 3 is located inside the second housing 12. The inner cylinder 13 is provided with a ventilation hole 131 connected to the air inlet 121. One end of the inner cylinder 13 is connected to the first housing 11 and sleeved on the inner peripheral side of the second housing 12. The wire clamping structure 3 covers the other end of the inner cylinder 13, so as to be disposed closer to the end of the second housing 12. The inner cylinder 13 connects the second housing 12 and the airflow channel, while also shielding the air inlet 121 to prevent external liquids or impurities from directly entering the hair dryer body 1 and affecting the normal operation of the hair dryer 100.

[0040] It should be noted that the main body 1 of the hair dryer is generally cylindrical. In this utility model, radial direction refers to the radial direction along the main body 1, circumferential direction refers to the circumferential direction along the main body 1, and axial direction refers to the axial direction along the main body 1. For ease of explanation, the directions of the components of the hair dryer 100 will be described below in terms of radial, circumferential, and axial directions. If the radial, circumferential, and axial directions of a particular component are specifically referred to, corresponding explanations will be provided.

[0041] It is understood that the air inlet 121 can be positioned close to the air inlet of the motor inside the hair dryer 100, while the air outlet 111 is positioned closer to the user's side. Preferably, the airflow duct extends axially, resulting in less air resistance and higher working efficiency. The exit point of the power cord 2 from the fan body can be determined according to the shape of the fan body. The power cord 2 can exit from the peripheral side of the fan body, or it can exit from the end of the fan body. Since a corresponding wire hole 123 needs to be provided at the exit point of the power cord 2, the air inlet 121 is generally not located on the same side as the wire hole 123 to prevent external dirt from entering the hair dryer 100 and affecting its normal operation.

[0042] Preferably, combined with Figure 2 and Figure 3As shown, when the air inlet 121 is located on the circumferential side of the hair dryer body 1, a wire hole 123 is provided at the end of the hair dryer body 1, through which the insulating part 22 protrudes. The second through hole 122 is located at the end of the hair dryer body 1 and is situated on the circumference of the wire hole 123. Of course, multiple air inlets 121 can be provided, arranged circumferentially along the hair dryer body 1, specifically along the circumferential direction of the second housing 12. This results in a smaller outer diameter of the hair dryer body 1 and a larger air intake area. By placing the insulating part 22 of the power cord 2 at the end of the hair dryer body 1, the power cord 2 is less prone to bending, thus reducing the risk of damage during use. Here, the front end refers to the end of the hair dryer 100 facing the user during normal use, and the end refers to the end facing away from the user, allowing the power cord 2 to be better connected to a power source (such as a socket) during normal use.

[0043] Regarding the wire clamping structure 3, the wire clamping structure 3 is fixedly connected to the blower body, wherein the wire clamping structure 3 and the blower body 1 can be directly or indirectly connected, specifically, in combination with Figures 3 to 5 As shown, a first mounting hole 35 is provided on the cable clamping structure 3, and a second mounting hole is provided on the blower body 1 or on other components (such as air guides, motors, or heating elements) located within the blower body 1. Screws or bolts are inserted into the first mounting hole 35 and the second mounting hole to fix the cable clamping structure 3 within the blower body. Furthermore, the cable clamping structure 3 secures the power cord 2, making it less susceptible to damage from pulling during use.

[0044] Specifically, the wire-clamping structure 3 is arranged in a ring shape and coaxially with the wire-passing hole 123. Preferably, the wire-passing hole 123 is circular, the wire-clamping structure 3 is annular, the insulating part 22 is sleeved on the wire-passing hole 123, the wire-clamping structure 3 is sleeved on the outer periphery of the power cord 2, and one side of the wire-clamping structure 3 abuts against the inner side of the second housing 12. The first through hole 313 is provided on the surface of the wire-clamping structure 3 extending radially thereafter, so as to better connect with the second through hole 122. At the same time, the wire-clamping structure 3 can form a barrier between the second through hole 122 and the electrical connection part 21, which can prevent external dirt from entering the hair dryer 100 and better protect the hair dryer 100.

[0045] Preferably, the electrical connection part 21 includes a conductor wire, which electrically connects the power supply device and the circuit board structure inside the blower to provide power to the blower 100. The insulation part 22 includes a wire sleeve, which is fitted on the inner periphery of the wire hole 123 and covers the outer periphery of the conductor wire. At least a portion of the conductor wire can extend from the front end of the wire sleeve to connect to the inside of the blower body 1. The wire clamping structure 3 has a first clamping part 31 that clamps onto the outer periphery of the wire sleeve and a second clamping part 32 that clamps onto the outer periphery of the conductor wire exposed at the front end of the wire sleeve. The first clamping part 31 clamps and fixes the wire sleeve, and the second clamping part 32 clamps and fixes the conductor wire. By fixing both the conductor wire and the wire sleeve, it is ensured that neither the conductor wire nor the wire sleeve will move relative to the other, thus providing better protection for the power cord 2.

[0046] Furthermore, such as Figure 3 As shown, the first locking portion 31 includes a first retaining ring sleeved on the outer periphery of the insulating portion 22, and the second locking portion 32 includes a second retaining ring sleeved on the outer periphery of the conductor wire. The first retaining ring and the second retaining ring are spaced apart along the axial direction of the wire hole 123 and form a stop-fitting engagement with the power line 2 along the axial direction of the wire hole 123. The first retaining ring and the second retaining ring limit the power line 2 in both the circumferential and axial directions, ensuring a better limiting effect.

[0047] The outer periphery of the sleeve is also provided with a snap-fit ​​groove for connection. Figure 3 and Figure 5 As shown, the first retaining ring includes a first half-ring 311 and a second half-ring 312 connected to each other. Both the first half-ring 311 and the second half-ring 312 are located within the retaining groove and are respectively engaged with both sides of the retaining groove along its radial direction. Disassembling the first retaining ring into two parts facilitates assembly. Furthermore, when the size of the cable sleeve changes slightly, the relative positions of the first half-ring 311 and the second half-ring 312 can be adjusted to adapt to the retaining requirements of power cords 2 of different sizes, thus improving applicability. A first mounting hole 35 is provided on each of the first half-ring 311 and the second half-ring 312 to fix them respectively, making assembly more convenient. By engaging the first half-ring 311 and the second half-ring 312 within the retaining groove, a stop-fit ​​is formed axially through the groove sidewalls, preventing the first retaining ring from moving relative to the cable sleeve.

[0048] Furthermore, the second retaining ring is located outside the retaining groove and forms a stop-fit ​​with the outer wall of the retaining groove along the axial direction of the thread hole 123. By the second retaining ring abutting against the outer side of the retaining groove, that is, the first retaining ring and the second retaining ring abutting against the two sides of the groove sidewall of the retaining groove respectively, both the first retaining ring and the second retaining ring are fixed relative to the retaining groove, resulting in more precise alignment and more reliable fixation.

[0049] It is understood that the first retaining ring and the second retaining ring can be integrally formed, and the corresponding second retaining ring can also be composed of two half-rings. Specifically, as shown in the example... Figure 5 As shown, a first locking protrusion 321 protrudes from one side of the axial direction of the first semi-ring 311, and a second locking protrusion 322 protrudes from one side of the axial direction of the second semi-ring 312. The first locking protrusion 321 and the second locking protrusion 322 are respectively engaged with the radial sides of the conductor wire to jointly form the second locking ring, making the assembly of the wire locking structure 3 and the power line 2 more convenient.

[0050] Moreover, combined Figure 6 and Figure 7 As shown, on the opposing surfaces of the first semi-ring 311 and the second semi-ring 312, one is provided with a positioning protrusion 33, and the other is provided with a positioning groove 34 that engages with the positioning protrusion 33. The positioning protrusion 33 and the positioning groove 34 engage radially along the power line 2. Through the engagement of the positioning protrusion 33 and the positioning groove 34, the first semi-ring 311 and the second semi-ring 312 can be quickly aligned, and their relative positional relationship can be more stable, thus providing a better fixation effect for the power line 2.

[0051] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structure made using the contents of the present utility model specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the patent protection scope of the present utility model.
