Even if they are placed in a fixed position, we cannot guarantee that our hands are completely dry and non-conductive when debugging or operating the hair dryer. It can be seen that the safety hazards of hair dryers cannot be avoided. Utility Model Content

[0023] Although the present application can be easily embodied in different forms of embodiments, only some of the specific embodiments are shown in the drawings and described in detail in this specification. It should be understood that this description should be regarded as an exemplary illustration of the principles of the present application and is not intended to limit the present application to that described herein.

[0024] Thus, a feature indicated in this specification will be used to illustrate one of the features of an embodiment of the present application, rather than implying that each embodiment of the present application must have the described feature. In addition, it should be noted that this specification describes many features. Although some features can be combined together to illustrate possible system designs, these features can also be used in other combinations that are not explicitly described. Thus, unless otherwise stated, the described combinations are not intended to be limiting.

[0025] In the embodiments shown in the drawings, the indications of directions (such as up, down, etc.) used to explain the structure and movement of various elements of the present application are not absolute but relative. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the description of the positions of these elements changes, the indications of these directions also change accordingly.

[0026] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these example embodiments are provided so that the description of the present application will be more comprehensive and complete and the concepts of the example embodiments will be fully conveyed to those skilled in the art. The accompanying drawings are only schematic illustrations of the present application and are not necessarily drawn to scale. The same reference numerals in the figures represent the same or similar parts, and thus their repeated description will be omitted.

[0027] Some embodiments of the present application provide a blowing device, the blowing device comprising:

[0028] A hair dryer, the hair dryer comprising a control device, a power circuit board and at least one detection element, the detection element being electrically connected to the control device and the power circuit board;

[0029] At least one expansion accessory is provided with a trigger portion suitable for triggering the detection element, and the trigger portion is configured with a preset feature corresponding to the type of the expansion accessory.

[0030] In this solution, a trigger part is provided on the extension accessory, and the trigger part is configured with preset features corresponding to the type of the extension accessory. The detection element is provided on the hair dryer, so that the type of the extension accessory is identified by sensing the trigger part through the detection element. In this way, the control device can control the hair dryer to run a mode or instruction corresponding to the type of the extension accessory according to the type of the extension accessory detected by the detection element, so as to realize the corresponding operation or debugging of the hair dryer using the extension accessory. It can be understood that the live parts in this device (such as the control device, the detection element, the power supply circuit board, etc.) are all integrated on the hair dryer on one side, and the extension accessory is configured with preset features corresponding to the type of the extension accessory by adapting the trigger part of the detection element. The extension accessory does not need to be energized or conductive during the identification process. In this way, when the extension accessory is used to debug or operate the hair dryer, the extension accessory can form a resistance between the human body and the hair dryer, greatly reducing the risk of electric shock.

[0031] In addition, in this embodiment, since the expansion accessories do not need to be configured with a power supply or electrical components, the cost of the expansion accessories can be reduced, the stability and safety of the expansion accessories can be improved, and it is also more conducive to reducing the open cost and product cost of expanding and upgrading the expansion accessories based on the hair dryer application scenario.

[0032] In a specific example, a plurality of the detection elements are provided on the hair dryer, and the plurality of the detection elements are arranged at intervals; the trigger portion includes one or more trigger sites, and the number and position of the trigger sites correspond to the type of the extended accessory, that is, the corresponding preset feature of the trigger portion is the number and position of the trigger sites, wherein the detection element can respond to the corresponding trigger site to send a signal to the control device. When the extended accessory is located at the target detection position defined by the detection element, the trigger site corresponds to the detection element one-to-one, so that the detection element corresponding to the trigger site sends a signal in response, and the detection element without the trigger site does not send a signal. In this way, the number and distribution of the trigger sites can be identified through the position and response state of the detection element, thereby identifying the type of the extended accessory.

[0033] Preferably, the number of the triggering sites is less than or equal to the number of the detection elements, so that at least a portion of the detection elements correspond to the triggering sites one-to-one. In this way, the different distribution positions of the triggering sites can be better utilized to form more types of preset feature possibilities.

[0034] Example 1

[0035] The detection element includes a Hall sensor, and one or more magnets are arranged on the extension accessory, and each of the magnets serves as a triggering site.

[0036] This example is used to explain in more detail.

[0037] The control device of the hair dryer is built-in with multiple drying modes, such as hair drying mode, clothes drying mode, and hand drying mode. It can be understood that the operating parameters of the hair dryer in different drying modes are different, and these parameters include, for example, temperature parameters, power parameters, time parameters, etc.

[0038] It should be noted that the type of this example is to illustrate the use of extended accessories to debug or operate a hair dryer, thereby realizing the switching of the corresponding modes or states of the hair dryer, breaking the existing condition that the human body needs to be in conductive contact with the hair dryer when debugging or operating the hair dryer, and expanding the use scenarios of the hair dryer in this field or other fields. Therefore, the drying modes (such as hair drying mode, clothes drying mode, and hand drying mode) illustrated in the example do not mean that in practice the hair dryer must simultaneously meet the three drying modes illustrated, nor do they mean that in practice the hair dryer has and only has these three drying modes. It can be understood that in addition to these three drying modes, the drying mode can also include a shoe drying mode, a glue drying mode, etc. It can be understood that the mode switching of the hair dryer is not limited to switching between drying modes, but in most cases it involves the switching of drying modes. In fact, the hair dryer can also be configured with an air intake mode, an on mode, an off mode, etc. In other embodiments, those skilled in the art or even users can flexibly set and configure these modes, which are not exhaustively listed here.

[0039] The following is a detailed example based on the three modes of hair drying mode, clothes drying mode, and hand drying mode, combined with the solution of installing two Hall sensors on the hair dryer:

[0040] The two Hall sensors of the hair dryer are named A and B based on the different positions of the two Hall sensors.

[0041] like Figure 1 As shown, an expansion accessory is provided, and the expansion accessory is specifically, for example, a hand dryer storage rack 2:

[0042] Based on the usage scenario that the hand dryer storage rack 2 is fixedly mounted on a wall for use, it is further configured as a storage rack type fixed on a wall. Specifically, a double-sided adhesive tape or a wall nail hole is provided on the hand dryer storage rack 2, so that the hand dryer storage rack 2 can be adhered to the wall or fixed on the wall by wall nails.

[0043] The hand dryer storage rack 2 is provided with a fan position for placing the hair dryer 1, and a magnet 7 is provided at the fan position. When the hair dryer 1 is located at the fan position, the Hall sensor A-5 corresponds to the magnet 7, and there is no magnet corresponding to the Hall sensor B-6. In this way, when the hair dryer 1 is located at the fan position, the Hall sensor A-5 detects the magnetic field and sends an electrical signal, which is represented by 1, and the Hall sensor B-6 does not send a signal, which is represented by 0. In this way, the signal fed back to the control device is represented by A1B0, and the A1B0 signal controls the hair dryer 1 to run the hand dryer mode, that is, the hair dryer 1 automatically switches to the hand dryer mode to dry the mobile phone on the hand dryer storage rack.

[0044] like Figure 2 As shown, an expansion accessory is provided, and the expansion accessory is specifically, for example, a shoe drying rack 4:

[0045] Based on the usage scenario of the shoe drying rack 4 for drying shoes, the shoe drying rack 4 is configured as a frame that can be used to hang or place shoes, and a fan position for placing the hair dryer 1 is set on the frame, and a magnet 10 is set at the fan position. When the hair dryer 1 is located at the fan position, the Hall sensor B-6 corresponds to the magnet 10, and there is no magnet corresponding to the Hall sensor A-5. In this way, when the hair dryer 1 is located at the fan position, the Hall sensor B-6 detects the magnetic field and sends an electrical signal, and the signal is represented by 1. The Hall sensor A-5 does not send a signal, and the signal is represented by 0. In this way, the signal fed back to the control device is represented by A0B1, and the A0B1 signal controls the hair dryer 1 to run the shoe drying mode, and blows the shoes dry according to the wind speed, temperature, and time corresponding to the shoe drying mode.

[0046] like Figure 3 As shown, an extension accessory is provided, and the extension accessory is specifically a clothes drying rack 3:

[0047] Based on the usage scenario of the clothes drying rack 3 for drying clothes, the clothes drying rack 3 is configured as a frame that can be used to hang or place clothes, and a fan position for placing the hair dryer 1 is provided on the frame, and two magnets 8 and 9 are provided on the fan position. When the hair dryer 1 is located at the fan position, the Hall sensor A-5 corresponds to one of the magnets 8, and the Hall sensor B-6 corresponds to the other magnet 9. In this way, when the hair dryer 1 is located at the fan position, the Hall sensor A-5 detects the magnetic field and sends an electrical signal, and the signal is represented by 1. Similarly, the Hall sensor B-6 detects the magnetic field and sends an electrical signal, and the signal is represented by 1. In this way, the signal fed back to the control device is represented by A1B1, and the A1B1 signal controls the hair dryer 1 to run the drying mode, and blows the clothes dry according to the wind speed, temperature, and time corresponding to the drying mode.

[0048] Of course, it can be understood that the structure of configuring two Hall sensors 5 and 6 can also be further configured as a fourth configuration. The fourth mode can be specifically triggered and executed by the signal of A0B0, and no detailed examples will be given again.

[0049] Of course, the embodiments of the present application are not limited to the case where the detection element is a Hall sensor and the trigger point is a magnet. In other embodiments, the detection element can be set as a magnet and the trigger point can be set as a Hall sensor as required, which can also achieve the purpose of identifying and detecting extended accessories by the hair dryer.

[0050] In other embodiments, the detection element includes an infrared pair tube, the infrared pair tube includes an output end and a receiving end, and the extension accessory is provided with one or more light processing components, each of which serves as a triggering site. Specifically, in this example, the light processing component further uses a reflective component to reflect infrared rays from the output end to the receiving end, so that the infrared pair tube sends a signal in response. Of course, the present design is not limited to the form of the light processing part using the reflective part. In other embodiments, the light processing part can further use a light absorbing part or a through hole structure. The light absorbing part or the through hole structure is arranged in a dot matrix on a reflective surface. The light absorbing part absorbs the infrared rays from the emitting end or the through hole structure is used to allow the infrared rays from the emitting end to pass through. In this way, the receiving end of the infrared pair tube corresponding to the light absorbing part or the through hole structure cannot receive the infrared rays, and thus does not send out a signal in response. The detection element corresponding to the reflective part or the through hole structure receives the infrared rays at the receiving end due to the reflection effect of the reflective surface, and thus sends out a signal in response. In this way, the position and response state of the detection element can also be used to identify the number and distribution position of the light absorbing parts, thereby identifying the type of the expansion accessories.

[0051] In other embodiments, the detection element includes a micro switch, and one or more adapter structures are provided on the extension accessory, and the adapter structure includes a protrusion for pressing the micro switch. Of course, the present design is not limited to the form in which the adapter structure uses a protrusion to press the micro switch. In other embodiments, the adapter structure can further use pits, which are arranged in a dot matrix on a plane, and the pits are used to form an avoidance effect on the micro switch opposite thereto. In this way, the micro switch corresponding to the pit is not pressed and thus does not send a signal to respond, and the detection element without a pit corresponding thereto sends a signal to respond due to being pressed by the plane. In this way, the number and distribution of the pits can also be identified through the position and response state of the detection element, thereby identifying the type of the extension accessory.

[0052] In other embodiments, the detection element includes a touch spring, and one or more metal points are provided on the extension accessory, and each of the metal points serves as a trigger site.

[0053] In another specific example, at least one detection element on the hair dryer is a color sensor. The trigger unit specifically includes a color card disposed on the extension accessory, and the color displayed by the color card corresponds to the type of the extension accessory, that is, the corresponding preset feature of the trigger unit is the color displayed by the color card. When the extension accessory is located at the target detection position defined by the color sensor, the color card is exactly opposite to the color sensor, and the color on the color card is read by the color sensor, so that the type of the extension accessory is identified by the color correspondence.

[0054] In another specific example, at least one detection element on the hair dryer is an angle sensor. The trigger unit specifically includes a limiting structure provided on the extension accessory, the limiting structure is used to cooperate with the hair dryer so as to limit the installation of the hair dryer on the extension accessory, and make the hair dryer form an inclination angle relative to the extension accessory, and the inclination angle corresponds to the type of the extension accessory, that is, the corresponding preset feature of the trigger unit is a limiting structure for making the hair dryer present a corresponding inclination angle.

[0055] For example, the limiting structure includes a mounting hole for accommodating the hair dryer's barrel or handle, and the mounting hole is inclined at an inclined angle, so that when the hair dryer or the handle is accommodated in the mounting hole, the hair dryer forms an inclined angle corresponding to the mounting hole relative to the expansion accessory. At this time, the angle sensor of the hair dryer detects the inclination angle value, thereby identifying the type of the expansion accessory.

[0056] In a specific example, at least one detection element on the hair dryer is a camera. The triggering part can be a structural shape or pattern corresponding to the type of the extended accessory, that is, the corresponding preset feature of the triggering part is the structural shape or pattern of the extended accessory. The camera performs graphic recognition on the structural shape or pattern of the extended accessory, thereby identifying the type of the extended accessory.

[0057] Preferably, the extension accessory and the hair dryer are separately provided so that the two can be separated.

[0058] Example 2

[0059] The present embodiment provides a hair-drying device, which includes a hair dryer and an extension accessory. The hair dryer is provided with a control device, a power supply and a metal contact, and the extension accessory is provided with a sensing element adapted to the metal contact, and the sensing element specifically includes at least one of a contact, a connection terminal and a sensor. The sensing element is used to detect the metal contact, and is specifically used to respond to the proximity, contact or connection of the metal contact to send a sensing signal. The control device can receive the sensing signal in a wired or wireless manner, and control the hair dryer to execute a working mode corresponding to the sensing signal according to the sensing signal, or control the hair dryer to automatically turn on or off according to the sensing signal.

[0060] The power supply component is used to supply power to the sensing component of the extension accessory when the hair dryer is close to, in contact with, or connected to the extension accessory, so as to provide the electric energy required by the sensing component to perform detection work.

[0061] In this way, the extension accessory can be used to approach, touch or connect the hair dryer to achieve mode switching control or automatic opening or closing control of the hair dryer, without the need for the user to directly touch the hair dryer, thereby avoiding the safety hazard of electric shock when operating the hair dryer with wet hands.

[0062] Compared with the embodiment 2, the advantage of the embodiment 1 is that the expansion accessories do not need to be powered, thereby further reducing the risk of electric shock.

[0063] Example 3

[0064] The present embodiment provides a hair dryer, which includes a hair dryer and an extension accessory. A sensor and a power socket are provided on the extension accessory, the hair dryer is provided with a power connection terminal, the power connection terminal is detachably connected to the power socket to power the hair dryer, the sensor is used to detect a target trigger condition, and respond or not respond according to whether the target trigger condition is met, and the power connection terminal of the hair dryer is controlled to be powered on and off by the response or non-response state of the sensor on the extension accessory. The target trigger condition includes detecting a human body approaching, or recognizing a target gesture, etc.

[0065] In this way, the sensor on the expansion accessory can be used to detect the target trigger condition to control the power on and off of the power connection terminal of the hair dryer according to whether the target trigger condition is met. The user does not need to directly touch the hair dryer, avoiding the safety hazard of electric shock when operating the hair dryer with wet hands.

[0066] Compared with the third embodiment, the first embodiment has the advantages that no independent control circuit is required on the expansion accessory, the cost is lower, the functions are more abundant, and the mode switching function other than turning on and off the hair dryer can be realized. At the same time, the expansion accessory does not require an additional power cable, avoiding the risks of power cable heating and poor port contact.

[0067] In summary, in order to ensure the safe use of the hair dryer and improve the user experience, in some embodiments, a hair dryer fixing bracket with a sensor (such as embodiments 2 and 3) is proposed. On the one hand, such a design can place and fix the hair dryer to free your hands; on the other hand, it is equipped with a sensor that can detect the approach of an object, thereby automatically turning on or off the hair dryer or switching to different modes.

[0068] The triggering principle of the expansion accessories in Embodiments 2 and 3 is different in that the expansion accessories in Embodiment 1 do not need to be powered on, but only need a plurality of magnets to trigger the Hall sensor on the hair dryer to start the hair dryer or switch different modes. The advantages are: the cost of the expansion accessories can be greatly reduced; the service life can be increased; and the difficulty of use can be reduced because no additional power supply is required.

[0069] All electronic parts of the embodiment 1 are concentrated on the hair dryer, and physical structures or materials that can trigger the sensor on the hair dryer (including but not limited to magnets, light sources or reflective materials, color blocks, convex or concave structures, insulating or conductive materials, heat-insulating or heat-dissipating materials, etc., hereinafter referred to as trigger materials) are installed on other functional accessories (functional uses include but are not limited to: drying hands, drying clothes, blowing, inhaling, etc.), that is, extended accessories.

[0070] On the functional accessories, that is, the extended accessories, trigger materials are installed at different positions. When the hair dryer is approached, the sensors installed on the hair dryer detect the different positions or different states of the trigger materials, thereby triggering different events, such as turning the hair dryer on or off, or starting a certain mode.

[0071] For example, multiple Hall sensors are installed on a hair dryer. When the hair dryer is close to an expansion accessory, some Hall sensors detect the magnetic field and turn on the hair dryer or switch it to a certain mode, such as hand drying, clothes drying, or shoe drying. At this time, other sensors on the hair dryer, such as the distance sensor, will be activated when they detect that an object is approaching.

[0072] The main purpose of installing multiple Hall sensors is to achieve more combination functions. Take 2 groups as an example: there are three states: A0B1, A1B1, and A1B0. A and B refer to two Hall sensors, 1 and 0 are the two states when the magnetic field is detected and not detected. In addition, there is the state of A0B0 when the sensor does not detect the magnetic field at all.

[0073] The technical solution of Example 1 can give full play to the role of the hair dryer and expand more usage scenarios, but different scenarios have different requirements for wind force, temperature, and duration. In order to make it more convenient, correct, and safe for users to use, after adding multiple sets of sensors to the hair dryer, combined with accessories suitable for the corresponding scenarios, the following practical application scenarios can be well realized. Of course, not only Hall sensors can be used, but various sensors or switches that can be triggered can be installed on the hair dryer, and corresponding structures, materials, colors, etc. that can be detected by sensors can be installed on other functional accessories. The sensor can be triggered to return different values ​​through the position and state of the material, so that the hair dryer can be switched to different modes, such as on and off, different temperatures or wind speeds, etc. For example: a color sensor can be installed on the hair dryer, a red color block can be attached to the hand drying rack, and a green color block can be attached to the clothes drying rack. When the hair dryer is placed on the hand drying rack or the clothes drying rack, the color sensor will detect different colors and automatically switch to the corresponding mode. The sensor can also be replaced with an angle sensor. When placed on different structures, it will return the angle value of the corresponding range, so that the hair dryer can automatically switch to the corresponding mode. You can also use an infrared sensor (range finder) to replace the Hall sensor, so that you only need to open a corresponding hole in the structure to replace the magnet to achieve the same effect. Alternatively, the Hall sensor can be replaced with a touch switch, and the corresponding protrusions or pits on the extension accessories can be used to turn the touch switch on or off, which can also achieve the same purpose. You can even install a camera on the hair dryer for image recognition.

[0074] In some embodiments, a foolproof structure is provided on one of the hair dryer and the extension accessory, and the foolproof structure is used to cooperate with the other of the hair dryer and the extension accessory when the hair dryer and the extension accessory are assembled, so that the detection element corresponds to the trigger part. In this way, when the hair dryer and the extension accessory are assembled and matched, the foolproof structure can be used to achieve rapid positioning between the two to ensure that the detection element on the hair dryer accurately corresponds to the trigger part, avoiding problems such as misassembly or position deviation, so that the detection element responds to the detection of the trigger part more accurately, thereby more accurately automatically controlling the hair dryer to execute a mode or instruction matching the type of the extension accessory based on the type of the extension accessory, avoiding the problem of wrong response.

[0075] Optionally, the foolproof structure includes a groove, which is arranged on the extension accessory, and the inner bottom surface of the groove is correspondingly provided with a trigger part, and the hair dryer has a matching part (such as a convex block adapted to the groove) suitable for being embedded in the groove, and a detection element is arranged on the matching part, and when the matching part is embedded in the groove, the detection element corresponds to the trigger part. It has the advantages of simple structure, convenient processing and low cost.

[0076] Alternatively, in other embodiments, the fool-proof structure may also be designed to include a groove, which is disposed on the hair dryer, and a detection element is correspondingly disposed on the inner bottom surface of the groove, and the extension accessory has a mating portion suitable for embedding in the groove (such as a protrusion that fits in the groove, etc.), and one or more triggering portions are disposed on the mating portion, and when the mating portion is embedded in the groove, the detection element corresponds to the triggering portion.

[0077] Some embodiments of the present application provide a control method for a hair dryer, which is used for a hair dryer, wherein the hair dryer is provided with one or more detection elements, wherein the control method comprises the following steps:

[0078] Detecting and identifying the type of the extended accessory within the target detection range by the detection element;

[0079] Determining a drying mode corresponding to the type of the extended accessory according to the type of the extended accessory;

[0080] The hair dryer is controlled to execute the determined drying mode.

[0081] In the present solution, the type of the extension accessory is indicated by a preset shape feature, pattern feature or color feature. When the extension accessory is within the target detection range, the detection element further identifies the type of the extension accessory by detecting the shape feature, pattern feature or color feature of the identification trigger part, so that the control device can control the hair dryer to operate the drying mode corresponding to the type of the extension accessory according to the type of the extension accessory, thereby realizing the corresponding operation or debugging of the hair dryer using the extension accessory. It can be understood that the live parts in the present device (such as the control device, the detection element, the power circuit board, etc.) are all integrated on the hair dryer on one side, and the extension accessory is an insulating part.
