Description

Technical Field

[0001] This utility model relates to the field of hair dryer technology, and in particular to a care device. Background Technology

[0002] Hair dryers primarily function to accelerate hair drying by generating hot or cold air. They are also widely used in laboratories, physiotherapy rooms, industrial production, and art settings for localized drying, heating, and therapeutic purposes. Hair dryers are equipped with attachments such as essence filters, diffusers, and anti-flippery attachments. These attachments alter airflow to achieve purposes such as rapid hair drying, styling assistance, improved hair quality, and promotion of scalp health.

[0003] In related technologies, hair dryers and accessories are electrically connected via pins or contacts. However, the pins or contacts on the hair dryer and the pins or contacts on the accessories need to be accurately aligned to ensure current flow. This increases the complexity of installation between the hair dryer and accessories, restricts user use, and consequently affects the user's experience with the hair dryer. Utility Model Content

[0004] This invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one objective of this invention is to provide a nursing device that facilitates the electrical connection between a hair dryer and its accessories, and allows the accessories to rotate relative to the hair dryer. This saves alignment time between the hair dryer and its accessories, thereby facilitating installation and allowing the user to easily adjust the hair dryer's settings.

[0005] The nursing device according to this utility model includes: a hair dryer and an accessory. The hair dryer is provided with a first electrical contact portion, and the accessory is detachably connected to the hair dryer. The accessory is provided with a second electrical contact portion. The first electrical contact portion and the second electrical contact portion are in contact with each other, so that the hair dryer and the accessory are electrically connected. Among them, one of the first electrical contact portion and the second electrical contact portion is circular, and the other falls into the circular first electrical contact portion or the second electrical contact portion, so that the accessory can rotate relative to the hair dryer.

[0006] Therefore, by setting a first electrical contact on the hair dryer and a second electrical contact on the accessory, the first and second electrical contacts can selectively make contact, allowing the accessory to selectively connect to the hair dryer. Furthermore, one of the first and second electrical contacts is circular, and the other can fall within the circle. Since any point on the circle is equidistant from the center, the first and second electrical contacts can connect within the circumference of the circle. This eliminates the need to deliberately choose an angle when attaching the accessory to the hair dryer, improving user comfort. It also facilitates the rotation of the accessory relative to the hair dryer and maintains the electrical connection between the accessory and the hair dryer, saving alignment time and installation time. It also makes it easier for users to adjust the hair dryer's settings, thus enhancing the user experience.

[0007] In some examples of this utility model, one of the first electrical contact and the second electrical contact is circular, and the other is dot-shaped.

[0008] With this configuration, the first and second electrical contacts remain in contact even when the accessory and the hair dryer rotate relative to each other. This configuration facilitates contact between the first and second electrical contacts, ensures the reliability of the connection between the first and second electrical contacts, and saves alignment time for the electrical connection between the accessory and the hair dryer.

[0009] In some examples of this utility model, there are multiple point-shaped first electrical contacts or second electrical contacts, and the multiple point-shaped first electrical contacts or second electrical contacts are spaced apart and all fall into the circular first electrical contact or second electrical contact.

[0010] With this configuration, multiple point-like first or second electrical contacts can all fall into another circular second or first electrical contact. This ensures that each point-like first or second electrical contact is in contact with the circular first or second electrical contact. If one of the point-like first or second electrical contacts fails to make contact with the circular first or second electrical contact, or if the contact is loose, the other point-like first or second electrical contacts will still maintain contact with the circular first or second electrical contact. This ensures that even in extreme cases, the accessory and the hair dryer can maintain electrical connection, thereby improving the stability of the hair dryer's use.

[0011] In some examples of this utility model, the hair dryer is provided with a third electrical contact, and the first electrical contact is electrically connected to the third electrical contact; the accessory is provided with a fourth electrical contact and a resistor, and the second electrical contact is electrically connected to the fourth electrical contact; the first electrical contact is electrically connected to the second electrical contact, and the third electrical contact is electrically connected to the fourth electrical contact, so as to form a path for identifying the resistor.

[0012] With this configuration, the circuit between the first, second, third, and fourth electrical contacts identifies the corresponding resistance, thereby enabling the hair dryer to recognize accessories and thus improving the user experience.

[0013] In some examples of this utility model, the third electrical contact is disposed on the outside of the first electrical contact relative to the first electrical contact, and the fourth electrical contact is disposed on the outside of the second electrical contact; at least one of the third electrical contact and the fourth electrical contact is circular, and the other falls into the circular third electrical contact or the fourth electrical contact.

[0014] With this arrangement, the third electrical contact is positioned away from the center of the first electrical contact, and the fourth electrical contact is positioned away from the center of the second electrical contact. This facilitates contact between the first and second electrical contacts, as well as between the third and fourth electrical contacts. The third and fourth electrical contacts can make contact within the circumference, which increases the contact area between them. Moreover, the circular contact area allows the third and fourth electrical contacts to remain in contact even after rotating relative to each other at a certain angle, saving alignment time. Operators or users can rotate the accessory relative to the blower according to their actual needs.

[0015] In some examples of this utility model, one of the third electrical contact and the fourth electrical contact is circular, and the other is dot-shaped.

[0016] This setup saves alignment time between the third and fourth electrical contacts, allowing staff or users to rotate the accessory relative to the blower according to actual needs.

[0017] In some examples of this utility model, the third and fourth electrical contacts are both constructed as points, and the third and fourth electrical contacts are located at the rotation center of the accessory relative to the blower.

[0018] With this configuration, when the accessory rotates at a certain angle relative to the hair dryer, a rotation center will appear. The third and fourth electrical contacts are both located at the rotation center. When the accessory rotates relative to the hair dryer, the third and fourth electrical contacts can still maintain contact, thereby ensuring the stability of the electrical connection between the accessory and the hair dryer and improving the user experience.

[0019] In some examples of this utility model, one of the first and third electrical contacts on the hair dryer is circular, and the other is dot-shaped. The circular first or third electrical contact is closer to the accessory than the dot-shaped third or first electrical contact. Alternatively, one of the second and fourth electrical contacts on the accessory is circular, and the other is dot-shaped. The circular second or fourth electrical contact is closer to the hair dryer than the dot-shaped fourth or second electrical contact.

[0020] With this design, the height of the first electrical contact is greater than the height of the third electrical contact. When the hair dryer is accidentally dropped, the circular first electrical contact will touch the ground first, ensuring a large contact area and low pressure relative to the ground. The height of the fourth electrical contact is greater than the height of the second electrical contact. When the accessory is accidentally dropped, the circular fourth electrical contact will touch the ground first, ensuring a large contact area and low pressure relative to the ground. This avoids the point-like second electrical contact from forming a high-pressure contact with the ground, thus extending the lifespan of the hair dryer.

[0021] In some examples of this utility model, the hair dryer is provided with a fifth electrical contact, and the accessory is provided with a sixth electrical contact. The fifth and sixth electrical contacts are electrically connected so that the hair dryer can supply power to the accessory.

[0022] With this configuration, when the fifth and sixth electrical contacts come into contact, the accessory and the hair dryer can be electrically connected. Moreover, the function of the fifth and sixth electrical contacts is different from the function of the first and second electrical contacts, as well as the function of the third and fourth electrical contacts. The contact between the fifth and sixth electrical contacts ensures that the hair dryer can supply power to the accessory.

[0023] In some examples of this utility model, the fifth and sixth electrical contacts are both point-shaped, and the fifth and sixth electrical contacts are located at the rotation center of the accessory relative to the blower.

[0024] This design, with its dotted fifth and sixth electrical contacts, not only saves materials but also simplifies the structure of the electrical contacts. Furthermore, the fifth and sixth electrical contacts are positioned relative to each other at the center of the accessory's rotation relative to the blower. This arrangement ensures that the fifth and sixth electrical contacts remain in contact even when the user rotates the accessory, thus keeping the blower and accessory electrically connected at all times.

[0025] In some examples of this utility model, at least one of the fifth electrical contact and the sixth electrical contact is circular, and the other falls into the circular fifth or sixth electrical contact.

[0026] With this design, the circular contact area allows the fifth and sixth electrical contacts to remain in contact even after rotating relative to each other by a certain angle. This saves alignment time between the fifth and sixth electrical contacts. When the staff or user rotates the accessory relative to the hair dryer according to actual needs, the fifth and sixth electrical contacts will still remain in contact, and the accessory and hair dryer can still be electrically connected.

[0027] In some examples of this utility model, the first and third electrical contacts are circular, and the fifth electrical contact is dot-shaped; the second, fourth, and sixth electrical contacts are all dot-shaped.

[0028] With this design, the first and third electrical contacts protrude beyond the fifth electrical contact. When the hair dryer is accidentally dropped, the circular first and third electrical contacts will touch the ground first, ensuring a large contact area and low pressure relative to the ground. This avoids the point-shaped second, fourth, and sixth electrical contacts from forming a high-pressure contact with the ground, thus extending the lifespan of the hair dryer and its accessories.

[0029] In some examples of this utility model, the hair dryer includes a blower tube with an air outlet end, and a first electrical contact and a fifth electrical contact are disposed at the air outlet end; the accessory is provided with a mating end opposite to the air outlet end, and a second electrical contact and a sixth electrical contact are disposed at the mating end.

[0030] With this configuration, the docking end and the air outlet end are positioned opposite each other, which allows the first and second electrical contacts, as well as the fifth and sixth electrical contacts, to be positioned opposite each other. This facilitates contact between the first and second electrical contacts, as well as between the fifth and sixth electrical contacts, and simplifies the contact steps between the first and second electrical contacts and between the fifth and sixth electrical contacts.

[0031] In some examples of this utility model, the hair dryer includes an air inlet structure and an air inlet filter. The air inlet filter is detachably connected to the air inlet structure and is provided with a magnetic element. The air inlet structure is provided with a Hall element, which is used to detect the magnetic element to identify the installation and removal of the air inlet filter.

[0032] With this setup, the air inlet filter is installed behind the air inlet structure, and the magnetic component and Hall element are close to each other. When the air inlet filter is removed from the air inlet structure, the Hall element detects that the magnetic component has moved away, and at this time the blower performs the predetermined program.

[0033] In some examples of this utility model, the hair dryer also includes a motor, a heating element, and a controller, which can control the motor and / or the heating element to stop working based on the removal of the air inlet filter.

[0034] With this setup, when the air intake filter is installed on the air intake structure, the user can control the motor's operation via the controller, and the motor in turn controls the heating element to heat it. After the air intake filter is removed from the air intake structure, the controller can stop both the motor and the heating element from working, thus preventing safety issues caused by improper user operation.

[0035] In some examples of this utility model, the air inlet structure is provided with one of the anti-foolproof protrusion and anti-foolproof groove, and the air inlet filter is provided with the other of the anti-foolproof protrusion and anti-foolproof groove. The anti-foolproof protrusion and anti-foolproof groove are matched in the circumferential upper limit of the air inlet filter so that the magnetic component falls into the detection range of the Hall element.

[0036] With this configuration, when the air intake filter is installed on the air intake structure, the anti-foolproof protrusion passes through the anti-foolproof groove. This not only limits the position of the air intake filter on the air intake structure, reducing the difficulty of aligning the air intake filter and the air intake structure, but also ensures that the Hall element and the magnetic component are in close proximity. This saves the disassembly time between the air intake filter and the air intake structure, and also ensures the stability of the air intake filter installed on the air intake structure, as well as the accuracy of the Hall element in recognizing the magnetic component.

[0037] In some examples of this utility model, the hair dryer includes a blower tube, which includes a casing and a light-emitting element. The light-emitting element is disposed inside the casing, and a light-transmitting portion for transmitting light from the light-emitting element is formed around the peripheral side wall of the casing.

[0038] With this design, the light-transmitting part diffuses the light generated by the light-emitting element, allowing the light-emitting element to display various states of the hair dryer. The light-transmitting part also makes it easy for the user to observe and adjust the hair dryer's state according to their actual needs.

[0039] In some examples of this utility model, the cylindrical shell has a non-transparent decorative part in the middle of the light-transmitting part.

[0040] This design allows the decorative section to serve a decorative purpose for the hair dryer, while also concentrating the light emitted from the light-emitting element in the light-transmitting section. This makes it easier for users to focus on observing the light emitted from the light-transmitting section, thereby enhancing the practicality and technological sophistication of the hair dryer.

[0041] Compared with the prior art, this utility model adopts a first electrical contact part on the hair dryer and a second electrical contact part on the accessory. The first and second electrical contacts can selectively contact each other, allowing the accessory to selectively connect to the hair dryer. Moreover, one of the first and second electrical contacts is circular, and the other can fall into the circle. Since any point on the circle is equidistant from the center, the first and second electrical contacts can be connected within the circumference of the circle. This facilitates the rotation of the accessory relative to the hair dryer and maintains the electrical connection between the accessory and the hair dryer. This saves the alignment time between the hair dryer and the accessory, reduces the installation time between the hair dryer and the accessory, and makes it easier for users to adjust the status of the hair dryer, thereby improving the user experience.

[0057] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0058] The following is for reference. Figures 1-10 This invention describes a nursing appliance 100 according to an embodiment of the present invention. For example, the nursing appliance 100 may be a household appliance such as a hair dryer.

[0059] like Figures 1-3 As shown, the nursing device 100 according to this utility model includes: a hair dryer 10 and an accessory 20. The hair dryer 10 is provided with a first electrical contact portion 11. The accessory 20 is detachably connected to the hair dryer 10. The accessory 20 is provided with a second electrical contact portion 21. The first electrical contact portion 11 and the second electrical contact portion 21 are in contact with each other, so that the hair dryer 10 and the accessory 20 are electrically connected. Among them, one of the first electrical contact portion 11 and the second electrical contact portion 21 is circular, and the other falls into the circular first electrical contact portion 11 or the second electrical contact portion 21, so that the accessory 20 can rotate relative to the hair dryer 10.

[0060] It is understood that the hair dryer 10 and the accessory 20 constitute the main structure of the nursing device 100. The hair dryer 10 is provided with a first electrical contact part 11, and the accessory 20 is provided with a second electrical contact part 21. The accessory 20 can be selectively detached from the hair dryer 10. That is, the staff or user can install the accessory 20 on the hair dryer 10 or remove the accessory 20 from the hair dryer 10 according to actual usage needs. After the accessory 20 is connected to the hair dryer 10, the first electrical contact part 11 and the second electrical contact part 21 make contact, so that the accessory 20 and the hair dryer 10 can be electrically connected, thereby enabling the accessory 20 to add other functions to the hair dryer 10.

[0061] In this design, one of the first electrical contact 11 and the second electrical contact 21 is circular, and the other can fall into the circle. That is, the first electrical contact 11 is circular, and the second electrical contact 21 can fall on the circumference of the circle, or the second electrical contact 21 is circular, and the first electrical contact 11 can fall on the circumference of the circle. The distance from the center of the circle to the circumference is equal everywhere. The first electrical contact 11 and the second electrical contact 21 can make contact within the circumference range. This increases the contact area between the first electrical contact 11 and the second electrical contact 21. Moreover, the circular contact area allows the first electrical contact 11 and the second electrical contact 21 to remain in contact even after rotating relative to each other by a certain angle. This saves the alignment time between the first electrical contact 11 and the second electrical contact 21. The staff or user can rotate the accessory 20 relative to the hair dryer 10 according to actual needs. At this time, the first electrical contact 11 and the second electrical contact 21 still remain in contact, and the accessory 20 and the hair dryer 10 can still be electrically connected. This can improve the usage scenarios of the hair dryer 10 and thus enhance the user experience.

[0062] For example, both the first electrical contact 11 and the second electrical contact 21 are circular, and their circumferences are arranged opposite each other. After the accessory 20 rotates relative to the hair dryer 10 at a certain angle, the first electrical contact 11 and the second electrical contact 21 still remain in contact. Alternatively, the second electrical contact 21 can be dot-shaped, and the first electrical contact 11 can be circular. The dot-shaped second electrical contact 21 contacts the circumference of the first electrical contact 11. After the accessory 20 rotates relative to the hair dryer 10 at a certain angle, the first electrical contact 11 and the second electrical contact 21 still remain in contact. This can improve the usage scenarios of the hair dryer 10 and enhance the user experience.

[0063] Therefore, by providing a first electrical contact 11 on the hair dryer 10 and a second electrical contact 21 on the accessory 20, the first electrical contact 11 and the second electrical contact 21 can selectively contact each other. This allows the accessory 20 to selectively connect to the hair dryer 10. Moreover, one of the first electrical contact 11 and the second electrical contact 21 is circular, and the other can fall into the circle. Since any point on the circle is equidistant from the center, the first electrical contact 11 and the second electrical contact 21 can be connected within the circumference of the circle. This eliminates the need to deliberately choose an angle when attaching the accessory to the hair dryer 10, improving user comfort. It also facilitates the rotation of the accessory 20 relative to the hair dryer 10 and maintains the electrical connection between the accessory 20 and the hair dryer 10. This saves the alignment time between the hair dryer 10 and the accessory 20, reduces the installation time between the hair dryer 10 and the accessory 20, and makes it easier for the user to adjust the state of the hair dryer 10, thereby improving the user experience.

[0064] In particular, such as Figure 1 and Figure 2 As shown, one of the first electrical contact portion 11 and the second electrical contact portion 21 is circular, and the other is dot-shaped. For example, the first electrical contact 11 can be circular and the second electrical contact 21 can be dot-shaped, or the first electrical contact 11 can be dot-shaped and the second electrical contact 21 can be circular. The following example uses the first electrical contact 11 as circular and the second electrical contact 21 as dot-shaped. The circular first electrical contact 11 can be an annulus, which gives the circumference of the annulus a certain area. The dot-shaped second electrical contact 21 can be a pin, which can fall onto the annulus. When the accessory 20 rotates relative to the hair dryer 10 at a certain angle, the second electrical contact 21 rotates around the first electrical contact 11, and the first electrical contact 11 and the second electrical contact 21 remain in contact. This keeps the accessory 20 and the hair dryer 10 electrically connected. Users can select different functions formed by the rotation of the accessory 20 relative to the hair dryer 10 according to their actual needs. This can save the alignment time of the electrical connection between the accessory 20 and the hair dryer 10, ensure the reliability of the connection between the first electrical contact 11 and the second electrical contact 21, facilitate the installation of the accessory 20 and the hair dryer 10, enrich the usage scenarios of the hair dryer 10, and thus improve the user experience.

[0065] In addition, such as Figure 1 and Figure 2 As shown, there are multiple point-shaped first electrical contact portions 11 or second electrical contact portions 21, and the multiple point-shaped first electrical contact portions 11 or second electrical contact portions 21 are spaced apart and all fall into the circular first electrical contact portion 11 or second electrical contact portion 21.

[0066] It is understandable that one of the first electrical contact 11 and the second electrical contact 21 is configured as a dot, and there are multiple dot-shaped first electrical contact 11 or second electrical contact 21. These multiple dot-shaped first electrical contact 11 or second electrical contact 21 are evenly distributed, and each of the multiple dot-shaped first electrical contact 11 or second electrical contact 21 can fall into another circular second electrical contact 21 or first electrical contact 11. This ensures that each dot-shaped first electrical contact 11 or second electrical contact 21 is in contact with the circular first electrical contact 11 or second electrical contact 21. When the contact between one of the dot-shaped first electrical contact 11 or second electrical contact 21 and the circular first electrical contact 11 or second electrical contact 21 fails or becomes loose, the other dot-shaped first electrical contact 11 or second electrical contact 21 still maintains contact with the circular first electrical contact 11 or second electrical contact 21. This ensures that, in extreme cases, the accessory 20 and the hair dryer 10 can maintain electrical connection, thereby improving the stability of the hair dryer 10 in use.

[0067] In addition, such as Figures 1-3As shown, the hair dryer 10 is provided with a third electrical contact 12, and the first electrical contact 11 is electrically connected to the third electrical contact 12; the accessory 20 is provided with a fourth electrical contact 22 and a resistor 23, and the second electrical contact 21 is electrically connected to the fourth electrical contact 22; the first electrical contact 11 is electrically connected to the second electrical contact 21, and the third electrical contact 12 is electrically connected to the fourth electrical contact 22 to form a path for identifying the resistor 23.

[0068] In other words, the hair dryer 10 is provided with a third electrical contact 12, and the first electrical contact 11 and the third electrical contact 12 are electrically connected to ensure the flow of current in the hair dryer 10. The accessory 20 is provided with a fourth electrical contact 22, and the second electrical contact 21 and the fourth electrical contact 22 are electrically connected to ensure the flow of current in the accessory 20. The first electrical contact 11 and the second electrical contact 21 are in contact, and the third electrical contact 12 and the fourth electrical contact 22 are in contact, so that a circuit is formed between the first electrical contact 11, the second electrical contact 21, the third electrical contact 12 and the fourth electrical contact 22, that is, the accessory 20 and the hair dryer 10 are electrically connected. Moreover, the accessory 20 is provided with a resistor 23, and different resistors 23 correspond to different functions. This allows the circuit between the first electrical contact 11, the second electrical contact 21, the third electrical contact 12 and the fourth electrical contact 22 to identify the corresponding resistor 23, thereby enabling the hair dryer 10 to have the function of identifying accessories, thereby improving the user experience. For example, different resistor values ​​23 correspond to different wind speeds and temperatures, which ensures the proper application of the hair dryer 10 in different usage scenarios.

[0069] In addition, such as Figure 1 and Figure 2 As shown, the third electrical contact 12 is disposed on the outside of the first electrical contact 11 relative to the first electrical contact 11, and the fourth electrical contact 22 is disposed on the outside of the second electrical contact 21; at least one of the third electrical contact 12 and the fourth electrical contact 22 is circular, and the other falls into the circular third electrical contact 12 or the fourth electrical contact 22.

[0070] It is understood that the following description uses the example of the first electrical contact 11 being circular, the second electrical contact 21 being dot-shaped, the third electrical contact 12 being dot-shaped, and the fourth electrical contact 22 being circular. The third electrical contact 12 is located outside the first electrical contact 11, that is, the third electrical contact 12 is arranged away from the center of the first electrical contact 11. The fourth electrical contact 22 is located outside the second electrical contact 21, that is, the fourth electrical contact 22 is arranged away from the center of the second electrical contact 21. This facilitates the contact between the first electrical contact 11 and the second electrical contact 21, as well as the contact between the third electrical contact 12 and the fourth electrical contact 22, thereby facilitating the electrical connection between the accessory 20 and the hair dryer 10.

[0071] In this design, one of the third electrical contact 12 and the fourth electrical contact 22 is circular, and the other can fall into a circle. That is, the third electrical contact 12 is circular, and the fourth electrical contact 22 can fall on the circumference of the circle, or the fourth electrical contact 22 is circular, and the third electrical contact 12 can fall on the circumference of the circle. The distance from the center of the circle to the circumference is equal everywhere, and the third electrical contact 12 and the fourth electrical contact 22 can make contact within the circumference. This increases the contact area between the third electrical contact 12 and the fourth electrical contact 22. Moreover, the circular contact area allows the third electrical contact 12 and the fourth electrical contact 22 to remain in contact even after rotating relative to each other by a certain angle, which saves the alignment time between the third electrical contact 12 and the fourth electrical contact 22. The staff or user can rotate the accessory 20 relative to the hair dryer 10 according to actual needs. At this time, the third electrical contact 12 and the fourth electrical contact 22 still remain in contact, and the accessory 20 and the hair dryer 10 can still be electrically connected, thereby expanding the usage scenarios of the hair dryer 10 and improving the user experience.

[0072] For example, both the third electrical contact 12 and the fourth electrical contact 22 are circular, and their circumferences are arranged opposite each other. After the accessory 20 rotates relative to the hair dryer 10 at a certain angle, the third electrical contact 12 and the fourth electrical contact 22 still remain in contact. Alternatively, the third electrical contact 12 can be dot-shaped, and the fourth electrical contact 22 can be circular. The dot-shaped third electrical contact 12 contacts the circumference of the fourth electrical contact 22. After the accessory 20 rotates relative to the hair dryer 10 at a certain angle, the third electrical contact 12 and the fourth electrical contact 22 still remain in contact. This can improve the usage scenarios of the hair dryer 10 and enhance the user experience.

[0073] In addition, such as Figure 1 and Figure 2 As shown, both the third electrical contact 12 and the fourth electrical contact 22 are constructed as dots, and the third electrical contact 12 and the fourth electrical contact 22 are located at the rotation center of the accessory 20 relative to the blower 10.

[0074] In other words, both the third electrical contact 12 and the fourth electrical contact 22 are designed as point-like structures. This not only saves materials and simplifies the structure of the electrical contacts, but also facilitates their placement on the hair dryer 10 and the accessory 20, respectively. Furthermore, the relative arrangement of the third electrical contact 12 and the fourth electrical contact 22 ensures their contact. When the accessory 20 rotates relative to the hair dryer 10 at a certain angle, a rotation center will appear. Both the third electrical contact 12 and the fourth electrical contact 22 are located at this rotation center. Even when the accessory 20 rotates relative to the hair dryer 10 (by the user, not automatically), the third electrical contact 12 and the fourth electrical contact 22 can still maintain contact, thus ensuring the stability of the electrical connection between the accessory 20 and the hair dryer 10 and improving the user experience.

[0075] In addition, such as Figure 1 and Figure 2 As shown, on the hair dryer 10, one of the first electrical contact 11 and the third electrical contact 12 is circular, and the other is dot-shaped. The circular first electrical contact 11 or the third electrical contact 12 is closer to the accessory 20 relative to the dot-shaped third electrical contact 12 or the first electrical contact 11; or, on the accessory 20, one of the second electrical contact 21 and the fourth electrical contact 22 is circular, and the other is dot-shaped. The circular second electrical contact 21 or the fourth electrical contact 22 is closer to the hair dryer 10 relative to the dot-shaped fourth electrical contact 22 or the second electrical contact 21.

[0076] It is understandable that the first electrical contact 11 and the third electrical contact 12 are disposed on the hair dryer 10, and the second electrical contact 21 and the fourth electrical contact 22 are disposed on the accessory 20. One of the first electrical contact 11 and the third electrical contact 12 is circular, and the other is dot-shaped. That is, if the first electrical contact 11 is circular, the third electrical contact 12 is dot-shaped, and if the first electrical contact 11 is dot-shaped, the third electrical contact 12 is circular. The following description uses the example of the first electrical contact 11 being circular and the third electrical contact 12 being dot-shaped. The circular first electrical contact 11... The first electrical contact 11 is positioned closer to the third electrical contact 12 than the third electrical contact 12, allowing the first electrical contact 11 to protrude beyond the third electrical contact 12. This ensures that when the hair dryer 10 is accidentally dropped, the circular first electrical contact 11 contacts the ground first, guaranteeing a larger contact area and lower pressure relative to the ground. This prevents the point-shaped third electrical contact 12 from contacting the ground under high pressure, thus extending the lifespan of the hair dryer 10.

[0077] Similarly, one of the second electrical contact 21 and the fourth electrical contact 22 is circular, and the other is dot-shaped. That is, if the second electrical contact 21 is circular, the fourth electrical contact 22 is dot-shaped, and vice versa. The following example uses the second electrical contact 21 as dot-shaped and the fourth electrical contact 22 as circular. The circular fourth electrical contact 22 is closer to the hair dryer 10 than the second electrical contact 21. This allows the height of the fourth electrical contact 22 to be greater than the height of the second electrical contact 21, and also allows the fourth electrical contact 22 to protrude from the second electrical contact 21. When the accessory 20 is accidentally dropped, the circular fourth electrical contact 22 will contact the ground first, ensuring that the circular fourth electrical contact 22 has a larger contact area with the ground and a smaller pressure relative to the ground. This avoids the dot-shaped second electrical contact 21 forming a contact with the ground with greater pressure, thereby extending the service life of the hair dryer 10.

[0078] In addition, such as Figure 1 As shown in Figure 3, the hair dryer 10 is provided with a fifth electrical contact 13, and the accessory 20 is provided with a sixth electrical contact 24. The fifth electrical contact 13 and the sixth electrical contact 24 are electrically connected, so that the hair dryer 10 can supply power to the accessory 20.

[0079] In other words, the hair dryer 10 is provided with a fifth electrical contact 13, and the accessory 20 is provided with a sixth electrical contact 24. When the fifth electrical contact 13 and the sixth electrical contact 24 come into contact, the accessory 20 and the hair dryer 10 can be electrically connected. Moreover, the function of the fifth electrical contact 13 and the sixth electrical contact 24 is different from the function of the first electrical contact 11 and the second electrical contact 21, as well as the function of the third electrical contact 12 and the fourth electrical contact 22. The contact of the fifth electrical contact 13 and the sixth electrical contact 24 can ensure that the hair dryer 10 supplies power to the accessory 20. On this basis, the contact of the first electrical contact 11 and the second electrical contact 21, as well as the contact of the third electrical contact 12 and the fourth electrical contact 22, can enable the hair dryer 10 to utilize different functions of the accessory 20. That is, the hair dryer 10 can identify different accessories 20, so that the power supply or function switching between the hair dryer 10 and the accessory 20 does not interfere with each other, which is convenient for users or staff to repair or maintain, thereby extending the service life of the hair dryer 10 and ensuring the completeness of the functions of the hair dryer 10.

[0080] Among them, such as Figure 1 and Figure 2 As shown, both the fifth electrical contact 13 and the sixth electrical contact 24 are point-shaped, and the fifth electrical contact 13 and the sixth electrical contact 24 are located at the rotation center of the accessory 20 relative to the blower 10.

[0081] Understandably, the dotted fifth electrical contact 13 and sixth electrical contact 24 not only save materials but also simplify the structure of the electrical contacts. They also facilitate the placement of the fifth electrical contact 13 and sixth electrical contact 24 on the hair dryer 10 and accessory 20, respectively. Furthermore, the fifth electrical contact 13 and sixth electrical contact 24 are positioned relative to the center of rotation of accessory 20 relative to hair dryer 10. This arrangement ensures that the fifth electrical contact 13 and sixth electrical contact 24 remain in contact when the user rotates accessory 20, thus keeping hair dryer 10 and accessory 20 electrically connected. This guarantees the stability of hair dryer 10 and allows the user to switch between different functions of hair dryer 10 while maintaining connection between hair dryer 10 and accessory 20.

[0082] Specifically, at least one of the fifth electrical contact 13 and the sixth electrical contact 24 is circular, and the other falls into the circular fifth electrical contact 13 or the sixth electrical contact 24.

[0083] In other words, one of the fifth electrical contact 13 and the sixth electrical contact 24 is circular, and the other can fall into a circle. That is, the fifth electrical contact 13 is circular, and the sixth electrical contact 24 can fall on the circumference of the circle, or the sixth electrical contact 24 is circular, and the fifth electrical contact 13 can fall on the circumference of the circle. The distance from the center of the circle to the circumference is equal everywhere. The fifth electrical contact 13 and the sixth electrical contact 24 can make contact within the circumference. This increases the contact area between the fifth electrical contact 13 and the sixth electrical contact 24. Moreover, the circular contact area allows the fifth electrical contact 13 and the sixth electrical contact 24 to still make contact after rotating relative to each other at a certain angle. This saves the alignment time between the fifth electrical contact 13 and the sixth electrical contact 24. The staff or user can rotate the accessory 20 relative to the hair dryer 10 according to actual needs. At this time, the fifth electrical contact 13 and the sixth electrical contact 24 still remain in contact, and the accessory 20 and the hair dryer 10 can still be electrically connected. This can improve the usage scenarios of the hair dryer 10 and thus improve the user experience.

[0084] For example, both the fifth electrical contact 13 and the sixth electrical contact 24 are circular, and their circumferences are arranged opposite each other. After the accessory 20 rotates relative to the hair dryer 10 at a certain angle, the fifth electrical contact 13 and the sixth electrical contact 24 still remain in contact. Alternatively, the fifth electrical contact 13 can be dot-shaped, and the sixth electrical contact 24 can be circular. The dot-shaped fifth electrical contact 13 contacts the circumference of the sixth electrical contact 24. After the accessory 20 rotates relative to the hair dryer 10 at a certain angle, the fifth electrical contact 13 and the sixth electrical contact 24 still remain in contact. This can improve the usage scenarios of the hair dryer 10 and enhance the user experience.

[0085] In particular, such as Figure 1 and Figure 2 As shown, the first electrical contact 11 and the third electrical contact 12 are circular, and the fifth electrical contact 13 is dot-shaped; the second electrical contact 21, the fourth electrical contact 22 and the sixth electrical contact 24 are all dot-shaped.

[0086] Understandably, the first electrical contact 11, the third electrical contact 12, and the fifth electrical contact 13 are disposed on the hair dryer 10, and the second electrical contact 21, the fourth electrical contact 22, and the sixth electrical contact 24 are disposed on the accessory 20. The first electrical contact 11 and the third electrical contact 12 are circular, and the fifth electrical contact 13 is dot-shaped. The height of the circular first electrical contact 11 and the third electrical contact 12 is greater than that of the dot-shaped fifth electrical contact 13, that is, the first electrical contact 11 and the third electrical contact 12 protrude from the fifth electrical contact 13. When the hair dryer 10 is accidentally dropped, the circular first electrical contact 11 and the third electrical contact 12 will contact the ground first, which can ensure that the circular first electrical contact 11 and the third electrical contact 12 have a larger contact area with the ground and a smaller pressure relative to the ground. This can avoid the dot-shaped fifth electrical contact 13 from forming a contact with the ground with greater pressure, thereby extending the service life of the hair dryer 10.

[0087] In addition, the second electrical contact 21, the fourth electrical contact 22 and the sixth electrical contact 24 are all dot-shaped. When the hair dryer 10 is accidentally dropped, the dot-shaped second electrical contact 21, the fourth electrical contact 22 and the sixth electrical contact 24 can avoid contact with the ground with a large pressure, thereby extending the service life of the hair dryer 10 and the accessory 20.

[0088] In addition, such as Figure 4 , Figure 5 and Figure 7 As shown, the hair dryer 10 includes a blower tube 30, which has an air outlet end 31. A first electrical contact 11 and a fifth electrical contact 13 are disposed on the air outlet end 31. The accessory 20 is provided with a docking end opposite to the air outlet end 31, and a second electrical contact 21 and a sixth electrical contact 24 are disposed on the docking end.

[0089] In other words, the air outlet 31 is provided on the air duct 30, and the air outlet 31 faces the user, so that the blower 10 can blow air to the user through the air outlet 31. The air duct 30 is provided with a first electrical contact 11 and a fifth electrical contact 13, and the accessory 20 is provided with a second electrical contact 21 and a sixth electrical contact 24. Moreover, the accessory 20 is provided with a docking end, which is arranged opposite to the air outlet 31. This allows the first electrical contact 11 and the second electrical contact 21 to be arranged opposite to each other, and the fifth electrical contact 13 and the sixth electrical contact 24 to be arranged opposite to each other. This facilitates the contact of the first electrical contact 11 and the second electrical contact 21, and the fifth electrical contact 13 and the sixth electrical contact 24, and simplifies the contact steps of the first electrical contact 11 and the second electrical contact 21, and the fifth electrical contact 13 and the sixth electrical contact 24. This facilitates the installation between the accessory 20 and the blower 10, and ensures the electrical connection between the accessory 20 and the blower 10.

[0090] In addition, such as Figure 4 , Figure 5 and Figures 8-10 As shown, the hair dryer 10 includes an air inlet structure 32 and an air inlet filter 33. The air inlet filter 33 is detachably connected to the air inlet structure 32. The air inlet filter 33 is provided with a magnetic element 331. The air inlet structure 32 is provided with a Hall element 321. The Hall element 321 is used to detect the magnetic element 331, thereby identifying the installation and removal of the air inlet filter 33.

[0091] Understandably, the air inlet filter 33 is detachable from the air inlet structure 32. When external air is about to enter the blower 10, the air inlet filter 33 can filter the air, preventing impurities in the air from entering the air inlet structure 32. This allows the air inlet structure 32 to process the impurity-free air, thereby preventing blockage inside the blower 10 and purifying the air blown out by the blower 10, thus improving the user experience. For example, the air inlet structure 32 is the air inlet end of the blower 30. External air enters the blower 10 through the air inlet end, is processed, and finally blown out from the air outlet end 31, thus ensuring air circulation within the blower 10.

[0092] The air inlet filter 33 has a magnetic element 331 on one side and a Hall element 321 on one side of the air inlet structure 32. After the air inlet filter 33 is installed on the air inlet structure 32, the magnetic element 331 and the Hall element 321 are close to each other. When the air inlet filter 33 is removed from the air inlet structure 32, the Hall element 321 detects that the magnetic element 331 is away. At this time, the hair dryer 10 performs a predetermined program, thereby improving the safety of the hair dryer 10.

[0093] In addition, such as Figure 3As shown, the hair dryer 10 also includes a motor, a heating element, and a controller 40, which can control the motor and heating element to stop working based on the removal of the air inlet filter 33.

[0094] In other words, the hair dryer 10 is equipped with a motor, a heating element, and a controller 40. When the air inlet filter 33 is installed on the air inlet structure 32, the user can control the operation of the motor through the controller 40, and the motor can then control the heating element to heat the air. After the air inlet filter 33 is removed from the air inlet structure 32, the controller 40 can stop both the motor and the heating element from working, thereby preventing safety issues caused by improper operation by the user and thus improving the safety of the hair dryer 10.

[0095] Specifically, when the user cleans the air inlet filter 33, after removing the air inlet filter 33 from the air inlet structure 32, the Hall element 321 detects that the magnetic component 331 is gradually moving away from itself. At this time, the controller 40 controls the motor and heater to supply power, and the motor and heater stop working. When the user installs the air inlet filter 33 on the air inlet structure 32, the Hall element 321 detects that the magnetic component 331 is gradually approaching itself until it is completely close. At this time, the controller 40 controls the motor and heater to be ready to work at any time, thereby preventing safety problems caused by improper operation by the user and thus improving the safety of the hair dryer 10.

[0096] In addition, such as Figure 9 and Figure 10 As shown, the air inlet structure 32 is provided with one of the anti-mistake protrusion 332 and the anti-mistake groove 322, and the air inlet filter 33 is provided with the other of the anti-mistake protrusion 332 and the anti-mistake groove 322. The anti-mistake protrusion 332 and the anti-mistake groove 322 are matched in the circumferential direction of the air inlet filter 33 so that the magnetic component 331 falls into the detection range of the Hall element 321.

[0097] For example, the air inlet structure 32 is provided with a foolproof groove 322, and the air inlet filter 33 is provided with a foolproof protrusion 332. The foolproof protrusion 332 and the foolproof groove 322 can be matched in a limiting manner. The foolproof groove 322 is provided in the outer circumferential direction of the air inlet structure 32, and the foolproof protrusion 332 is provided in the inner circumferential direction of the air inlet filter 33. Moreover, the foolproof protrusion 332 extends along the length direction of the air inlet filter 33. When the air inlet filter 33 is installed on the air inlet structure 32, the foolproof protrusion 332 passes through the foolproof groove 322. This not only allows the air inlet structure 32 to limit the air inlet filter 33, reducing the difficulty of aligning the air inlet filter 33 and the air inlet structure 32, but also ensures that the Hall element 321 and the magnetic component 331 are close to each other, thereby saving the disassembly time between the air inlet filter 33 and the air inlet structure 32. It also ensures the stability of the air inlet filter 33 installed on the air inlet structure 32, as well as the accuracy of the Hall element 321 in recognizing the magnetic component 331.

[0098] In addition, such as Figure 6 As shown, the hair dryer 10 includes a blower tube 30, which includes a casing 34 and a light-emitting element 35. The light-emitting element 35 is disposed inside the casing 34, and a light-transmitting portion 36 for transmitting light from the light-emitting element 35 is formed around the peripheral side wall of the casing 34.

[0099] It is understandable that a light-emitting element 35 and a light-transmitting part 36 are installed inside the casing 34. This protects the light-emitting element 35 and the light-transmitting part 36, thereby extending their service life. The light-emitting element 35 is located inside the casing 34, and the light-transmitting part 36 is attached to the inner circumferential side wall of the casing 34, extending in an arc along the inner side of the casing 34. This allows the light-transmitting part 36 to diffuse the light generated by the light-emitting element 35, enabling the light-emitting element 35 to display various states of the hair dryer 10. The light-transmitting part 36 facilitates user observation, allowing the user to adjust the status of the hair dryer 10 according to actual needs. For example, the light-emitting element 35 and the light-transmitting part 36 can be fixed inside the casing 34 by snap-fitting, bonding, or threaded connection, ensuring their stability. The light-emitting element 35 can provide corresponding lights for heating temperature or fan speed settings, allowing the user to adjust them according to actual needs.

[0100] In addition, such as Figure 7 As shown, the barrel shell 34 has a non-transparent decorative part 37 in the middle of the light-transmitting part 36. That is, the decorative part 37 is set on the outer peripheral surface of the barrel shell 34, and the decorative part 37 corresponds to the middle of the light-transmitting part 36. It not only serves a decorative purpose for the hair dryer 10, but also allows the light emitted by the light-emitting element 35 in the light-transmitting part 36 to be focused in one place, so that the user can focus on observing the light emitted by the light-transmitting part 36, thereby improving the practicality and technological sophistication of the hair dryer 10.
