Description

Technical Field

[0001] The utility model relates to the technical field of hairdressing appliances, in particular to a high-speed hair dryer adopting a horizontally placed motor mechanism. Background Art

[0002] Hair dryers are commonly used household appliances, mainly used for drying and shaping hair, and can also be used for local drying, heating and treatment in laboratories, physiotherapy rooms, industrial production, art, etc., and are widely used. In particular, hot hair dryers are used for a variety of purposes, such as drying materials (such as paint and hair), and cleaning or stripping surface layers.

[0003] Existing hair dryers can be roughly divided into two types according to the different air inlet locations:

[0004] One is the rear-intake hair dryer, in which the motor assembly is located at the rear end of the hair dryer body and air is sucked in from the rear end. The sucked air is heated by the heating assembly at the front end of the hair dryer body and then flows out of the body, or flows out after passing through an additional air nozzle. Traditional hair dryers mostly use this air intake method, but due to the influence of the central motor assembly and heating assembly, the central flow velocity of the airflow in the hair dryer is slow and the temperature is high, which brings disadvantages such as poor user experience and reduced life of the motor assembly and heating assembly.

[0005] The second is a handle-type air intake hair dryer. The motor assembly of this type of hair dryer is located inside the handle and inhales air from the bottom of the handle. After the inhaled air passes through the handle, the fluid path is turned and enters the hair dryer body. It is heated by the heating component on the hair dryer body and then flows out of the body, or flows out after passing through an additional nozzle. Most existing high-speed hair dryers use this air intake method, which not only effectively increases the flow rate of the inhaled air flow, but also has a suitable temperature, which can effectively avoid damage caused by high temperature. This type of hair dryer is most famous for products of Dyson Technology Co., Ltd., and has become popular all over the world in recent years.

[0006] Prior art example 1, referring to patent document CN104273920B, the applicant Dyson Technology Co., Ltd. discloses a hair care appliance, including a handle, the handle including a wall and an outer wall, wherein the wall defines a main fluid flow path extending from the main fluid inlet into the appliance and the outer wall is the outer surface of the appliance. The outer wall may extend substantially continuously around the wall and along the wall. An isolation layer may be provided between the wall and the outer wall, the isolation layer may be substantially around and along the wall, and may reduce one or more of the noise, vibration and heat generated by the appliance. The handle may include a fan unit for sucking fluid into the main fluid flow inlet and traveling along the main fluid flow path. Through the description and drawings of Example 1, it can be inferred without doubt that in the hair care appliance, the motor is placed vertically in the handle, the air enters from the annular hole at the lower end of the handle, enters the handle after turning 90 degrees, enters the body after turning 90 degrees, and finally sprays out from the front end of the body. Its defects are: 1. During the movement of airflow, it needs to go through multiple large-angle turns of 90 degrees or close to 90 degrees, which will cause a lot of turbulence and lead to a decrease in air outlet speed; 2. Due to the large-angle turns, the airflow will directly and continuously impact the handle and body, resulting in a large noise. The recorded test value is 82db; 3. The motor is set in the handle, and the user holds the handle to use it. In the absence of a good buffer structure, long-term use can easily cause discomfort in the hand.

[0007] Prior art example 2, referring to patent document CN116439488A, the applicant Shenzhen Zhongqu Motor Co., Ltd. discloses a low-noise, high-pressure high-speed hair dryer. It includes a hair dryer, a handle, and a high-speed motor. The hair dryer is provided with an air outlet, a first air inlet, a second air inlet, and an air duct fusion chamber. The first air inlet constitutes a first air duct, the handle is provided with a handle air inlet hole, the handle is connected to the second air inlet of the hair dryer to constitute a second air duct, the first air duct and the second air duct converge to the air duct fusion chamber, and the high-speed motor is arranged between the air outlet and the air duct fusion chamber. The present invention provides sufficient air intake by forming a double air duct air intake structure, and converges the two air ducts to the air duct fusion chamber to complement and fuse each other, thereby ensuring the stability of the air intake of the high-speed motor, improving the working efficiency of the high-speed motor, enabling the entire high-speed hair dryer to maintain high air pressure and high air volume air intake and outlet, and also achieving the effect of noise reduction. Through the content description and drawings of Example 1, it can be inferred without a doubt that although the high-speed motor is arranged in the wind tube of the high-speed hair dryer, its air inlet is located at the lower end of the handle, which will cause the entire air duct to be too long, and there is a large 90-degree turn between the handle and the wind tube, which will cause a lot of turbulence, resulting in a decrease in the air outlet speed. Summary of the invention

[0008] In order to overcome the above-mentioned deficiencies in the prior art, the utility model provides a high-speed hair dryer adopting a horizontally placed motor mechanism, so as to minimize the loss of wind speed and air volume and reduce the power consumption of the whole machine.

[0023] The preferred configuration of the thermal insulation bracket is that the thermal insulation bracket is located on the inner side of the focusing air outlet bracket, and a thermal insulation chamber is formed in the thermal insulation bracket, a negative ion generator is provided in the thermal insulation chamber, and a release end of the negative ion generator extends into the focusing air duct.

[0025] A handle chamber is formed in the handle housing, a button assembly is arranged in the handle housing, and the annular chamber is communicated with the handle chamber so that the circuit board assembly is electrically connected with the button assembly through a cable.

[0026] Furthermore, a cooling port is provided on the motor bracket, so that the motor air duct is connected with the annular chamber through the cooling port.

[0027] The beneficial effects of the present invention are that the high-speed fan motor is arranged upward and horizontally in the internal air duct of the wind cylinder housing, instead of being arranged in the handle housing, and the air inlet, internal air duct, high-speed fan motor and air outlet are arranged in the same direction, so that, firstly, the length of the air duct between the air outlet and the air inlet can be greatly shortened, and secondly, the air outlet is directly opposite to the air inlet, so as to eliminate the 90-degree turn of the airflow, minimize the loss of wind speed and air volume, reduce the power consumption of the whole machine, improve the air outlet wind speed and air volume, and enable users to have a better use effect.

[0044] Embodiment 1

[0045] Reference Figures 1 to 12 , a high-speed hair dryer adopting a horizontal motor mechanism, comprising:

[0046] The air cylinder housing 1 has an air inlet 11 at one end and an air outlet 12 at the other end, and the air cylinder housing 1 has an internal air duct 3, and the air inlet 11 is connected to the air outlet 12 through the internal air duct 3;

[0047] A handle housing 2 is mounted on the lower end of the blower housing 1;

[0048] A high-speed fan motor 4 is used to draw in outside air through the air inlet 11 and then blow it out through the air outlet 12;

[0049] The high-speed fan motor 4 is transversely arranged in the internal air duct 3 so that the air inlet 11, the internal air duct 3, the high-speed fan motor 4 and the air outlet 12 are arranged in the same direction.

[0050] The above content is the basic structural scheme of the present utility model, in which the high-speed fan motor 4 is arranged upward and horizontally in the internal air duct 3 of the wind cylinder housing 1, instead of being arranged in the handle housing 2, and the air inlet 11, the internal air duct 3, the high-speed fan motor 4 and the air outlet 12 are arranged in the same direction, so that, firstly, the length of the air duct between the air outlet 12 and the air inlet 11 can be greatly shortened, and secondly, the air outlet 12 is directly opposite to the air inlet 11, so as to eliminate the 90-degree turn of the airflow, minimize the loss of wind speed and air volume, reduce the power consumption of the whole machine, and improve the air outlet wind speed and air volume, so that users can have a better use effect.

[0051] Regarding the further configuration of this embodiment, a motor bracket 51 is provided in the internal air duct 3 to provide installation space, so that the high-speed fan motor 4 can be stably installed in the motor bracket 51. In addition, the high-speed fan motor 4 divides the internal air duct 3 into an air inlet duct 31, a motor duct 32 and an air outlet duct 33; the air inlet duct 31 is provided with an air inlet grille 52, a guide bracket 53 and a honeycomb rectifier bracket 54 from back to front; the air outlet duct 33 is provided with a diversion bracket 55, a converging outlet bracket 56 and a heat insulation bracket 57 from back to front. The high-speed fan motor 4 in the motor duct 32 is started to provide power and guide the nearby airflow, and then the external airflow enters the air inlet duct 31 through the air inlet 11 at the rear end of the wind tube housing 1, and then enters the air outlet duct 33 after passing through the motor duct 32, and finally blows out to the outside from the air outlet 12 at the front end of the wind tube housing 1. The airflow passing through the wind cylinder housing 1 has its wind speed greatly increased and can be heated by the heating component 6, thereby providing an effective blowing effect.

[0052] Embodiment 2

[0053] Based on the structure of the first embodiment, this embodiment provides a more preferred structural solution for the components in each air duct, as follows:

[0054] 1. Air inlet grille 52: Refer to Figure 4 The air inlet grille 52 is provided with a plurality of air inlet sieve holes 521. The air inlet pores can screen the air and block large-sized impurities (such as hair, etc.) in the air, so that the air inlet grille 52 can play a good protective role on the internal air duct 3.

[0055] 2. Guide bracket 53 and honeycomb rectifying bracket 54: refer to Figure 5 to Figure 7 An S-shaped rotating air duct 531 is formed between the guide bracket 53 and the honeycomb rectifying bracket 54 , and a honeycomb rectifying hole 541 is opened on the honeycomb rectifying bracket 54 .

[0056] The setting of the S-shaped rotating air duct 531 can effectively guide the airflow to form an "S"-shaped movement, with both horizontal and vertical flows, and disperse the noise more comprehensively to various places, thereby reducing the flow noise. The setting of the honeycomb rectifying hole 541, through the setting of the honeycomb hole, makes the airflow finally only enter the motor bracket 51 through the honeycomb hole. The honeycomb hole can absorb part of the fluctuation energy when the gas fluctuates, thereby reducing the impact of the airflow on the honeycomb air intake bracket, improving stability, reducing impact and noise, and having a good rectifying effect on the airflow. At the same time, the noise generated by the operation of the high-speed fan motor 4 can be blocked by the honeycomb hole structure to reduce the motor noise.

[0057] 3. Shunt stent 55: refer to Figure 8The diversion bracket 55 includes a plurality of equally spaced diversion ribs 551 , and equidistant air ducts 552 are formed between adjacent diversion ribs 551 , so that the air volume at each angle and each area is more uniform.

[0058] 4. Converging air outlet bracket 56: refer to Figure 10-11 , a converging air duct 561 is formed in the converging air outlet bracket 56, and a heating component 6 is provided in the converging air duct 561. The converging air duct 561 is generally shaped larger at the back and smaller at the front, so as to achieve the effect of converging and pressurizing, making the air outlet more concentrated, faster, and with a larger air volume per unit time, so that users have a better use experience. In addition, by setting the heating component 6, the airflow in the last section of the internal air duct 3 (the converging air duct 561) before the air outlet can be heated to eject hot air, and the heat loss can be reduced, the heat utilization rate can be improved, and the temperature of the air outlet 12 can be made more stable.

[0059] Preferably, the heating component 6 is further configured as follows: the heating component 6 includes several groups of heating units 61, and the heating units 61 correspond to the equidistant air ducts 552 one by one, and each group of heating units 61 includes one large heating plate 611 and one small heating plate 612. One heating unit 61 corresponds to one equidistant air duct 552, so that the heating component 6 has the same heating effect on each equidistant air duct 552; at the same time, each heating unit 61 includes a large heating plate 611 and a small heating plate 612, respectively, and the heating can be started separately or simultaneously, so that the airflow is heated to different temperatures, and cold airflow, low-temperature hot airflow, high-temperature hot airflow, etc. are ejected to meet the control requirements of different temperature levels.

[0060] 5. Heat insulation bracket 57: refer to Figure 10-11 The heat-insulating bracket 57 is located on the inner side of the concentrated air outlet bracket 56, and a heat-insulating chamber 571 is formed in the heat-insulating bracket 57. A negative ion generator 572 is arranged in the heat-insulating chamber 571, and a release end 573 of the negative ion generator 572 extends into the concentrated air duct 561. The heat-insulating bracket 57 plays the role of space separation, so that the temperature in the heat-insulating chamber 571 is lower than that in the concentrated air duct 561, thereby providing a lower temperature and safer operating environment for the negative ion generator 572. At the same time, the release end 573 of the negative ion generator 572 extends into the concentrated air duct 561, so that the airflow of the air outlet 12 can carry a negative ion effect, which has a maintenance effect on the user's hair.

[0061] Embodiment 3

[0062] Reference Fig.12In this embodiment, an annular chamber 7 is formed between the rear end of the motor bracket 51 and the front end of the honeycomb rectifier bracket 54. A circuit board assembly 71 is provided in the annular chamber 7. The circuit board assembly 71 serves as the control center of the entire hair dryer and provides power to various electrical components.

[0063] A handle chamber 21 is formed in the handle housing 2, and a button assembly 22 is provided in the handle housing 2. The annular chamber 7 is communicated with the handle chamber 21, so that the circuit board assembly 71 is electrically connected to the button assembly 22 through the cable 72. The user can communicate with the circuit board assembly 71 by operating the button assembly 22 to control the operation of each component. Preferably, the button assembly 22 or the circuit board assembly 71 is electrically connected to an external power source through a cable 23.

[0064] Preferably, the motor bracket 51 is provided with a cooling port 511, so that the motor air duct 32 is connected with the annular chamber 7 through the cooling port 511. Therefore, a part of the cold air flow in the motor air duct 32 can enter the annular chamber 7 through the cooling port 511, thereby increasing fluidity, cooling the annular chamber 7 and the circuit board assembly 71, so that the circuit board assembly 71 can operate stably for a long time.

[0065] It is worth noting that other technical solutions of the present invention belong to the prior art and will not be described in detail.

[0066] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the concept of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
