Description

Technical Field

[0001] The present invention relates to the technical field of product structure of small household appliances and use methods thereof, in particular to a method for using multiple functional modes of a hair dryer and the hair dryer and a support thereof. 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] The most popular high-speed hair dryer on the market is, for example, prior art example 1, referring to patent document CN221012304U, which discloses a high-speed hair dryer, comprising a hair dryer housing, an air supply assembly, a heating assembly and a control assembly, which comprises a handle portion and a head portion, the handle portion is provided with an air inlet, the head portion is provided with an air outlet, and an air flow channel for connecting the air inlet and the air outlet is also provided in the hair dryer body; the air supply assembly is provided in the air flow channel; the heating assembly is provided in the air flow channel and is located above the air supply assembly; the control assembly at least comprises a PCB board and a plurality of control switches for triggering the PCB board; an electrical cavity separated from the air flow channel is also provided in the head portion, the control assembly is provided in the electrical cavity, and the control switch passes through the side wall of the head portion and is exposed to the outside; the utility model arranges the control assembly including the control switch in the head portion of the hair dryer housing, so that the air flow channel in the handle portion remains straight and smooth, and an electrical cavity is provided in the head portion for accommodating the control assembly. Technical Example 1 shows a hair dryer with an overall "T" shape, which is also the shape with the highest market share. When used, the handle is held in the hand and the head of the machine blows out air. Its main function is to dry the hair.

[0004] In addition to the hairdressing function, the hair dryer also has the function of drying objects. For example, in some special cases, such as when you need to wear a damp piece of clothing urgently but there is no other drying equipment, the hair dryer can be used to dry the clothing. By heating the clothing partially or as a whole, the evaporation of water is accelerated, making the clothing dry as quickly as possible. Conventionally, in order to achieve the object drying function, the user needs to hold the hair dryer for a long time, which causes great pressure on the arm and the user can feel obvious discomfort. Therefore, in practice, few users choose to use a hair dryer to dry objects. On the other hand, the stability when holding the hair dryer is not good, and it will shake constantly, which can easily cause uneven drying effect, and even the items will be partially damaged due to the continuous high temperature, which is a bad experience.

[0005] In order to realize the multifunctional use of the hair dryer, some answers are given in the prior art.

[0006] As in prior art example 2, referring to patent document CN213429845U, a hand dryer is disclosed, which includes: a hair dryer; and a second shell, wherein a first groove is provided on the second shell, and the hair dryer is detachably fixed in the first groove, and a second air inlet and a second air duct corresponding to the air inlet and air outlet of the hair dryer are also provided on the second shell; the hair dryer is provided with a first metal contact electrically connected to an internal switch circuit, and a second metal contact electrically connected to the first metal contact and an induction switch are also provided in the second shell, and the induction switch is electrically connected to the second metal contact for controlling the opening and closing of the hair dryer. This application solves the problem in the related art that the hand dryer is an independent machine, cannot be used in conjunction with other devices in terms of structure, and the overall structure is relatively complex. The solution shown in Technical Example 2 has many limitations in terms of usage, for example: 1. In order to realize the hand drying function (equivalent to the object drying function), it must be used in conjunction with the second shell, because the induction switch is integrated on the second shell. If the hair dryer is used alone, the hand drying function cannot be activated; 2. The structural solution of the second shell and the hair dryer provided is only applicable to the strip-shaped first shell (hair dryer), which is the most common "T"-shaped hair dryer on the market. Technical Example 2 does not provide a corresponding solution; 3. When in use, the first metal contact on the hair dryer is in contact with the second metal contact on the second shell,

[0007] In order to achieve contact, the first metal contact and the second metal contact are exposed to the outside, which poses many hidden dangers, such as the risk of electric shock, short circuit and fire hazards, oxidation and corrosion, signal transmission interference, unstable electrical connection, etc.; 4. The second shell is a covered type. During the use of the hand drying function, the air flow may be insufficient due to the size limitation of the air inlet and outlet, which may lead to poor use effect. Summary of the invention

[0008] In order to overcome the above-mentioned deficiencies in the prior art, the present invention provides a method for using a hair dryer in multiple functional modes.

[0009] The technical solution of the present invention to solve the technical problem is: a method for using multiple functional modes of a hair dryer, comprising:

[0010] Air-drying mode: the user operates the mode switch button to switch the hair dryer to the air-drying mode, and places the hair dryer on a support. The gravity sensor needs to detect that the hair dryer is placed correctly and then feedback the third gravity sensing monitoring signal to the control circuit board; then, when the object to be air-dried is placed under the hair dryer, the object sensor on the hair dryer detects the object to be air-dried, and the object sensor feedbacks the first infrared monitoring signal to the control circuit board, and the air-drying mode is officially started, and the control circuit board controls the hair dryer to output air flow toward the object to be air-dried; when the object sensor on the hair dryer does not detect the object to be air-dried, the object sensor feedbacks the second infrared monitoring signal to the control circuit board, and the control circuit board controls the hair dryer not to output air flow to the outside;

[0011] Gravity sensing protection mode: When the hair dryer is powered on and started, if the gravity sensor detects that the hair dryer lies on the table or falls suddenly, the gravity sensing protection mode is automatically activated, and the gravity sensor feeds back the first gravity sensing monitoring signal to the control circuit board, so that the control circuit board controls the hair dryer to switch to standby and no longer output air flow to the outside; if the gravity sensor detects that the user picks up the hair dryer again, the gravity sensor feeds back the second gravity sensing monitoring signal to the control circuit board, so that the control circuit board controls the hair dryer to output air flow to the outside again according to the last working mode;

[0012] Blowing mode: When the hair dryer is taken out from the support and powered on, the user operates the mode switch button to switch the hair dryer to the blowing mode, and adjusts the motor speed of the hair dryer through the wind speed button to control the wind speed of the air flow output by the hair dryer; adjusts the heating power of the heating element in the hair dryer through the temperature button to control the temperature of the air flow output by the hair dryer.

[0013] Preferably, the hair dryer has at least a first speed gear and a second speed gear, wherein the motor speed is 86000 r / min at the first speed gear, and the motor speed is 103000 r / min at the second speed gear.

[0014] Preferably, in the blowing mode, the hair dryer has at least one temperature level, a second temperature level and a third temperature level, wherein the first temperature level outputs cold air, the second temperature level outputs warm air, and the third temperature level outputs hot air. The first temperature level is 50°C, the second temperature level is 70°C, and the third temperature level is 90°C.

[0015] In some optional embodiments of the present invention, there is also a health care hot compress mode. When the hair dryer is taken out from the support and powered on, the user controls the mode switch key to switch the hair dryer to the health care hot compress mode.

[0016] In the health care hot compress mode, the motor continuously maintains a first gear speed, and the temperature of the output air flow continuously cycles between 45℃ / 48℃ / 51℃ with an interval of N1 seconds. In the health care hot compress mode, the total running time is 30 minutes before the machine stops.

[0017] In some optional embodiments of the present invention, there is also a self-cleaning mode. When the hair dryer is taken out from the support and powered on, the user simultaneously operates the mode switch key and the temperature key to switch the hair dryer to the self-cleaning mode.

[0018] In self-cleaning mode, the motor continuously maintains the second gear speed, the hair dryer outputs the first gear temperature, and the motor rotates in the opposite direction. After N2 seconds in self-cleaning mode, it automatically returns to the working mode before switching to self-cleaning mode.

[0019] In some optional embodiments of the present invention, there is also a child mode. When the hair dryer is taken out from the support and powered on, the user controls the mode switch key to switch the hair dryer to the child mode.

[0020] In children's mode, the motor keeps the speed at the first gear and the hair dryer outputs the temperature at the first gear.

[0021] Another key solution of the present invention is a hair dryer having the above-mentioned method for using the hair dryer in multiple functional modes, comprising a handheld housing and a hair dryer housing, wherein the air inlet of the hair dryer is arranged at the rear end of the hair dryer housing or / and the lower end of the handheld housing, and the air outlet of the hair dryer is arranged at the front end of the hair dryer housing, and an internal air duct is formed between the air inlet and the air outlet;

[0022] A motor installed in a handheld housing or a blower housing;

[0023] A heating element, which is installed in the air cylinder housing and is located near the air outlet;

[0024] A gravity sensor installed in a handheld housing or a hair dryer housing;

[0025] an object sensor mounted in the handheld housing;

[0026] A control circuit board is disposed inside the handheld housing, and the control circuit board is electrically connected to the motor, the heating element, the gravity sensor and the object sensor respectively;

[0027] The handheld housing has a first side wall and a second side wall, and the first side wall is closer to the air outlet than the second side wall;

[0028] A detection hole is provided on the first side wall, the object sensor is arranged at the detection hole, a mode switching key is provided on the first side wall, and the control circuit board is in communication connection with the mode switching key;

[0029] The second side wall is provided with a wind speed key, a temperature key and an on / off key, and the control circuit board is respectively connected to the wind speed key, the temperature key and the on / off key in communication;

[0030] Optionally, a display panel assembly is provided on the end of the hair dryer shell away from the air outlet, and the control circuit board is communicatively connected with the display panel assembly, and the display panel assembly can display one or more of the functional mode information, temperature information, and wind speed information of the hair dryer.

[0031] Optionally, a voice announcer is also included, and the control circuit boards are respectively connected to the voice announcer for communication;

[0032] When the functional mode of the hair dryer is switched, the voice announcer plays the sound of the corresponding functional mode.

[0033] Another key solution of the present invention is a support, which is applied to the hair dryer as described above, wherein the support is a wall-mounted bracket, and the wall-mounted bracket is "L"-shaped as a whole, and includes a support section and a wall-mounted section;

[0034] The wall hanging section is used to be connected to an external supporting surface;

[0035] The support section is provided with an air outlet hole and a detection hole. When the hair dryer is placed on the support section, the end of the hair cylinder shell away from the air outlet is exposed to the outside, the air outlet hole is opposite to the air outlet of the hair dryer, and the detection hole is opposite to the object sensor on the hair dryer.

[0036] The beneficial effects of the present invention are:

[0037] 1. The hair dryer, wall-mounted bracket and use method provided by the present invention have multiple functional modes, including but not limited to air-drying mode, gravity sensing protection mode, air outlet mode, health hot compress mode, self-cleaning mode and children's mode, so as to meet more functional needs of users.

[0038] Second, in air-drying mode, it can not only dry hands, but also dry clothes, food and other objects. In addition, there are two trigger conditions, which is equivalent to realizing the automatic start and stop function in air-drying mode. The user does not need to press buttons on the hair dryer, which is more convenient to use and avoids the risk of forgetting to turn it off after use.

[0039] 3. The hair dryer can start the air-drying mode on a support (wall bracket) or start the air-drying mode alone.

[0040] Fourth, the solution of the present invention is applicable to "T"-shaped hair dryers, so as to meet the needs of upgrading and optimizing hair dryers with higher market share.

[0041] 5. While meeting the requirements of the air-drying mode, the structural components of the first metal contact and the second metal contact are eliminated, thereby avoiding circuit safety hazards.

[0042] 5. The support (wall bracket) is an open structure, so the wall bracket will not block the air inlet and outlet of the hair dryer, and can ensure smooth import and export. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0059] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0060] Embodiment 1

[0061] Reference Figure 1 to Figure 15 , a method for using multiple functional modes of a hair dryer 1, comprising:

[0062] Air-drying mode: the user operates the mode switching key 1112 to switch the hair dryer 1 to the air-drying mode, and places the hair dryer 1 on a support. The gravity sensor 15 needs to detect that the hair dryer 1 is placed correctly and then feedback a third gravity sensing monitoring signal to the control circuit board; then, when the object 3 to be air-dried is placed under the hair dryer 1, the object sensor 16 on the hair dryer 1 detects the object 3 to be air-dried, and the object sensor 16 feedbacks a first infrared monitoring signal to the control circuit board, and the air-drying mode is officially started, and the control circuit board controls the hair dryer 1 to output an air flow toward the object 3 to be air-dried; when the object sensor 16 on the hair dryer 1 does not detect the object 3 to be air-dried, the object sensor 16 feedbacks a second infrared monitoring signal to the control circuit board, and the control circuit board controls the hair dryer 1 not to output an air flow to the outside;

[0063] In the air-drying mode, two conditions need to be met at the same time to start the hair dryer. The first condition is that the gravity sensor 15 needs to be used to determine that the position of the hair dryer 1 is correct. The gravity performance of the hair dryer 1 in the handheld state and the non-handheld state is different. Therefore, the gravity sensor 15 can monitor the state of the hair dryer 1; the second condition is to determine whether the object 3 to be air-dried is approaching through the object sensor 16. When both conditions 1 and 2 are met, the control circuit board will control the hair dryer 1 to officially start the air-drying mode and output air flow; and when any one of the conditions 1 and 2 is not met, the control circuit board controls the hair dryer 1 not to start, so as to eliminate unnecessary operation of the hair dryer 1. Therefore, the setting of condition 1 is equivalent to forming the starting threshold of the air-drying mode; the setting of condition 2 is that the hair dryer 1 automatically blows air when the object 3 to be air-dried is approaching, and the hair dryer 1 automatically stops blowing air when the object 3 to be air-dried is approaching and moving away, which is equivalent to realizing the automatic start-stop function in the air-drying mode. The user does not need to press the button on the hair dryer 1, which is more convenient to use and avoids the risk of forgetting to turn it off after use.

[0064] It should be noted that the air-drying mode can be activated when the hair dryer 1 is placed on a support (wall bracket 2). In another case, when the hair dryer 1 is not placed on a support (wall bracket 2), the air-drying mode can also be activated as long as the hair dryer 1 is effectively clamped and in a relatively stable position. The obvious difference from the prior art 2 mentioned above is that the activation of the air-drying mode of the hair dryer 1 in the present invention is not restricted by the support (wall bracket 2).

[0065] Gravity sensing protection mode: When the hair dryer 1 is powered on and started, if the gravity sensor 15 detects that the hair dryer 1 lies on the table or falls suddenly, the gravity sensing protection mode is automatically started, and the gravity sensor 15 feeds back a first gravity sensing monitoring signal to the control circuit board, so that the control circuit board controls the hair dryer 1 to switch to standby and no longer output air flow to the outside; if the gravity sensor 15 detects that the user picks up the hair dryer 1 again, the gravity sensor 15 feeds back a second gravity sensing monitoring signal to the control circuit board, so that the control circuit board controls the hair dryer 1 to output air flow to the outside again according to the last working mode;

[0066] In the gravity sensing protection mode, when the hair dryer 1 is taken out from the support and used, if the user holds it normally, the gravity sensing protection mode is on standby at any time; if the user holds the hair dryer 1 unsteadily and accidentally drops it, or leaves suddenly due to an emergency and does not turn off the hair dryer 1, the gravity sensor 15 can monitor the changes in gravity information of the hair dryer 1 and feedback, and control the hair dryer 1 to stop blowing air through the control circuit board and maintain a standby state (not a closed state); once the user picks up the hair dryer 1 again, the gravity sensor 15 can monitor the changes in gravity information of the hair dryer 1 and feedback, and control the hair dryer 1 to restart and blow air through the control circuit board, and the mode before standby will be used when restarting, without the user having to press buttons again, which is safer, more economical, smarter and more convenient for users.

[0067] Blowing mode: When the hair dryer 1 is taken out from the support and powered on, the user operates the mode switch key 1112 to switch the hair dryer 1 to the blowing mode, and adjusts the speed of the motor 13 of the hair dryer 1 through the wind speed key 1121, thereby controlling the wind speed of the air flow output by the hair dryer 1 to the outside; adjusts the heating power of the heating element 14 in the hair dryer 1 through the temperature key 1122, thereby controlling the temperature of the air flow output by the hair dryer 1 to the outside.

[0068] In the blowing mode, the normal use function of the existing hair dryer 1 is consistent, and will not be described in detail here.

[0069] The preferred embodiment of the wind speed is that the hair dryer 1 has at least a first speed and a second speed, and the user switches the speed gear through the wind speed key 1121, and outputs different air volumes per unit time at different speeds. Preferably, the speed of the motor 13 is 86000r / min at the first speed, and the speed of the motor 13 is 103000r / min at the second speed. It should be noted that the specific values ​​of the speed of the motor 13 at each gear can be determined according to the performance indicators of the motor 13 itself or the actual needs of the user. It is only used as a preferred embodiment here, and no special limitation is made on the protection scope.

[0070] Regarding the preferred embodiment of the wind temperature, in the blowing mode, the hair dryer 1 has at least one temperature level, a second temperature level and a third temperature level, wherein the first temperature level outputs cold air, the second temperature level outputs warm air, and the third temperature level outputs hot air. Among them, the first temperature level is 50°C, the second temperature level is 70°C, and the third temperature level is 90°C. The user switches the speed level through the temperature key 1122, and outputs air flows of different temperatures at different temperatures to meet the user's usage needs in different scenarios. It should be noted that the specific values ​​of the temperatures at each level can be determined according to the performance indicators of the heating element 14 itself in the hair dryer 1, or the actual needs of the user. It is only used as a preferred embodiment here, and no special limitation is made on the scope of protection.

[0071] Based on the above solution, this embodiment provides more methods for using the functional modes, as follows:

[0072] 1. Health care hot compress mode: When the hair dryer 1 is taken out from the support and powered on, the user operates the mode switch key 1112 to switch the hair dryer 1 to the health care hot compress mode. It should be understood that the hair dryer 1 in the health care hot compress mode can mainly provide a hot compress function for the user. Similar to an infrared therapy instrument, the user's body is treated through infrared rays and temperature; unlike an infrared therapy instrument, the hair dryer 1 does not have an infrared function, but a hot air function instead, which treats the body through hot air flow and temperature, so that the user's body functions are restored.

[0073] It has been found through experiments that in the health care hot compress mode, too fast air flow speed may cause discomfort to the user. Therefore, preferably, in the health care hot compress mode, the motor 13 is continuously maintained at a first speed (for example, the speed of the motor 13 is 86000 r / min).

[0074] Another test shows that too low a temperature will cause the health care hot compress to have no good effect, and too high a temperature will burn the user's skin. If the air flow at the same temperature is continuously output, the effect of the health care hot compress will be unsatisfactory. Therefore, the actual scheme selected in this application is that in the health care hot compress mode, the temperature of the air flow output by the hair dryer 1 is continuously cycled between 45°C / 48°C / 51°C at intervals of N1 seconds (N1 is preferably 20), and the total duration in the health care hot compress mode is 30 minutes before shutting down. Among them, a temperature sensor 19 is arranged near the air outlet, and the real-time temperature of the air outlet 12a is monitored by the temperature sensor 19, which is then fed back to the control circuit board, and the control circuit board controls the heating power of the heating element 14 to achieve the purpose of adjusting the air outlet temperature.

[0075] 2. Self-cleaning mode: When the hair dryer 1 is taken out from the support and powered on, the user simultaneously operates the mode switch key 1112 and the temperature key 1122 to switch the hair dryer 1 to the self-cleaning mode, and the cleaning function of the inside of the hair dryer 1 can be realized without disassembly. The self-cleaning mode is used to remove dust, hair and other impurities accumulated inside the hair dryer 1 as much as possible, thereby reducing the interference of impurities on the circuit and preventing the circuit from having poor heat dissipation, signal interference, short circuit and burning due to impurities; secondly, it makes the internal air duct between the air inlet 11a and the air outlet 12a cleaner, eliminates the resistance caused by impurities, so that the air volume is large and stable, and the air outlet is smoother.

[0076] According to the test, a higher speed can achieve better cleaning effect in a shorter time, and the temperature has almost no effect on the cleaning effect. Therefore, preferably, in the self-cleaning mode, the motor 13 is continuously maintained at the second speed, the hair dryer 1 outputs the first temperature (to reduce power consumption), and the motor 13 rotates in the opposite direction, and the self-cleaning mode lasts for N2 seconds (N1 is preferably 30) and then automatically returns to the working mode before switching to the self-cleaning mode.

[0077] 3. Children's mode. When the hair dryer 1 is taken out from the support and powered on, the user operates the mode switch key 1112 to switch the hair dryer 1 to the children's mode; in the children's mode, the motor 13 continuously maintains a first speed and the hair dryer 1 outputs a first temperature.

[0078] In child mode, a combination of one speed gear and one temperature setting is adopted to form a low-temperature, slow air outlet effect, which can provide children with fun without causing harm to them. On the other hand, in child mode, the speed gear and temperature gear cannot be switched, which indirectly prevents the occurrence of high temperature and fast air outlet, preventing children from being injured during use, and plays a role similar to a child lock.

[0079] Embodiment 2

[0080] The solution provided in this embodiment is about a hair dryer 1, which has a method for using the hair dryer 1 with multiple functional modes as described in the first embodiment. Figure 3 to Figure 7 The specific structure of the hair dryer 1 includes:

[0081] A handheld shell 11 and a hair dryer shell 12, an air inlet 11a of the hair dryer 1 is arranged at the rear end of the hair dryer shell 12 or / and at the lower end of the handheld shell 11, and an air outlet 12a of the hair dryer 1 is arranged at the front end of the hair dryer shell 12, and an internal air duct is formed between the air inlet 11a and the air outlet 12a; a motor 13, which is installed in the handheld shell 11 or the hair dryer shell 12, and the motor 13 can generate a rotation speed of not less than 60000r / min during operation, thereby generating a high-speed airflow, sucking in external air from the air inlet 11a, accelerating it through the internal air duct, and finally ejecting it quickly from the air outlet 12a; a heating element 14, which is installed in the hair dryer shell 12, and the heating element 14 is located near the blowing port, and the heating element 14 is mainly used to heat the passing air flow so that the hair dryer 1 can eject warm air or hot air outward.

[0082] The gravity sensor 15 is installed in the handheld housing 11 or the hair dryer housing 12. The gravity sensor usually has a three-dimensional coordinate axis system (x, y, z axis), with the gravity sensor itself as the reference system. For example, for a horizontally placed sensor, the direction of gravity is perpendicular to the sensor plane, the gravity component in the x-axis and y-axis directions is 0, and the gravity component in the z-axis direction is mg. Therefore, once the position of the hair dryer 1 changes, its three-dimensional coordinate axis coefficients will definitely change, and the gravity sensor 15 can sense and monitor the position status of the hair dryer 1.

[0083] The object sensor 16 is installed in the handheld housing 11, and its main function is to sense and detect nearby objects, and sense the position and distance of the objects. In the air-drying mode, the control circuit board pregenerates an algorithm, that is, formulates a critical distance value X for whether the object 3 to be air-dried is close. When the monitoring value is less than X, the object sensor 16 feeds back a first infrared monitoring signal to the control circuit board; when the monitoring value is greater than or equal to X, the object sensor 16 feeds back a second infrared monitoring signal to the control circuit board. The object sensor 16 is a proximity sensor, an image sensor, a lidar sensor, a millimeter-wave radar sensor, etc., and the specific type is not specifically limited here.

[0084] The control circuit board 17 is disposed inside the handheld housing 11. The control circuit board 17 is electrically connected to the motor 13, the heating element 14, the gravity sensor 15 and the object sensor 16 respectively, and the control circuit board 17 can communicate with each component. The control circuit board 17 is connected to an external power source (such as a mains or a mobile power source) through a cable and powered on.

[0085] It should be particularly pointed out in the present invention that the handheld housing 11 has a first side wall 111 and a second side wall 112, and the first side wall 111 is closer to the air outlet 12a than the second side wall 112. In order to meet the use requirements in the air-drying mode, a detection hole 1111 is provided on the first side wall 111, and the object sensor 16 is arranged at the detection hole 1111 to provide installation and use space.
