Description

Technical Field

[0001] This utility model relates to the field of electric heating equipment technology, specifically a heating element mounting structure and a hot air device. Background Technology

[0002] There is a wide variety of electric heating products on the market, such as hair dryers, hot air blowers, and baking equipment, which are very convenient to use. However, the heating element of electric heating products usually needs to be powered on and heated by resistance. Some existing products have loose or poor contact between the heating element and the metal parts. If looseness or poor contact occurs during the power-on process, it may cause sparks at the contact point or even burn out the device itself, posing a safety hazard and making it inconvenient for users.

[0003] To address the above shortcomings, we need to develop a heating element mounting structure and hot air device to meet the needs of a wide range of users. Utility Model Content

[0004] Regarding the aforementioned safety hazards in existing electric heating products where the heating element and metal parts are loose or have poor contact, leading to sparks and potential burnout of the equipment, the technical solution adopted by this utility model is as follows:

[0005] A heating element mounting structure includes a heating component and a clamping component for detachably mounting the heating component. The heating component includes a heating element for generating heat when energized and a conductive element for connecting to an external power source. The clamping component elastically clamps the conductive element such that the conductive element presses against the heating element, and at least two of the conductive elements respectively contact the electrode surfaces at different positions of the heating element.

[0006] Furthermore, the clamping assembly includes a first clamping member and a second clamping member with a hollow through-structure. The first clamping member and the second clamping member are detachably connected and press the conductive member from the outside to the inside, so that the conductive member is in close contact with the electrode surface.

[0007] Furthermore, the clamping assembly includes an elastic deformable member for elastic clamping, the elastic deformable member being installed between the first clamping member and the second clamping member, such that the clamping assembly can elastically press the conductive member into close contact with the electrode surface.

[0008] Furthermore, the outer surface of the first clamping member has a first latch for engaging the second clamping member, and the inner surface of the second clamping member has a second latch for engaging the first clamping member. At least two of the first latches are circumferentially spaced around the center of the first clamping member, and at least two of the second latches are circumferentially spaced around the center of the second clamping member. The engagement of the first latches and the second latches can restrict the axial installation position of the first clamping member relative to the second clamping member.

[0009] Furthermore, the first buckle extends a first buckle edge a along the through direction of the hollow through structure, and the end of the first buckle edge a extends a second buckle edge b around the center of the first clamping member to limit the axial installation position of the first clamping member. The second buckle has a third buckle edge c extending around the center of the second clamping member. When the first buckle and the second buckle are engaged, the third buckle edge c limits the axial movement position of the second buckle edge b.

[0010] Furthermore, the heating element has a plurality of through heating holes between the two electrode surfaces, each electrode surface has an electrode layer for conducting the circuit, and the hole wall of the heating hole has a conductive heating layer connected to the electrode layer.

[0011] Furthermore, the conductive heating layer is formed into a planar heating layer using one of the following materials: nano-metal oxide, nano-semiconductor oxide, graphene, or carbon paste.

[0012] A hot air device, including the heating element mounting structure.

[0013] Furthermore, it includes a fan for air outlet and a fixed bracket for mounting the fan. The clamping assembly elastically clamps the fixed bracket, so that the fixed bracket presses the conductive element into close contact with the electrode surface of the heating element. The air outlet end of the fan is connected to the heating through hole of the heating element.

[0014] Furthermore, it includes a temperature sensor for detecting the heating temperature of the heating element, and a sensor positioning structure extending outward from the surface of the clamping assembly to limit the installation position of the temperature sensor. The probe end of the temperature sensor is connected to the heating element, and the heating circuit can be controlled by the temperature sensor to adjust the heating temperature of the heating element.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. This utility model uses a clamping assembly to clamp the conductive component onto the heating element using an elastic clamping method. This allows the conductive component to be elastically pressed and contact the electrode surface on the heating element. The elastic clamping method can stably hold the installation position of the conductive component, preventing it from easily becoming loose or having poor contact. This strengthens the connection stability between the conductive component and the heating element, which is beneficial to the stability of the circuit connection. It avoids safety hazards such as sparks or equipment burnout caused by loosening or poor contact, improves the safety of electric heating products, and makes them more convenient for users.

[0017] 2. This utility model employs an elastic deformation member between the first and second clamping members. During the clamping process, the elastic deformation member presses against the conductive member, enabling the conductive member to stably contact the electrode surface. The elastic deformation member itself has the characteristic of deformation under pressure, which reduces the production and installation precision required for component manufacturing and product installation. The elastic pressing effect can be achieved without precise matching, which helps to reduce production costs and improve production efficiency.

[0018] 3. This utility model has a temperature sensor installed on the hot air device to detect the heating temperature of the heating element. The user can control the heating circuit through the temperature sensor. When the heating element is overheated, the temperature sensor can disconnect the heating circuit. When the heating element is not heating, the temperature sensor can detect it in time. During the heating process, the temperature sensor can also adjust the heating temperature of the heating element to meet the needs of different temperature levels, so as to output hot air with different temperature requirements and make it convenient for users.

[0019] 4. The conductive heating layer of this utility model is formed by using one of the following materials: nano metal oxide, nano semiconductor metal oxide, graphene material, carbon paste material, etc., to form a planar heating layer. Preferably, nano semiconductor metal oxide is used and is attached to the surface of the heating through hole by physical vapor deposition. The adhesion thickness of nano semiconductor metal oxide is extremely small, and it has excellent electrical conductivity and thermal conductivity, which further reduces power loss and further concentrates the heat generation in the space inside the hole, reducing heat loss and ineffective heating.

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] Optionally, in some embodiments, the heating element 11 may be made of one of the following non-conductive materials: glass, ceramic, stone, plastic, etc. Preferably, the heating element 11 is made of ceramic. Ceramic has high hardness and is not easily damaged. Ceramic can withstand high temperatures and can be used in high-temperature environments for a long time without deformation or cracking. It has a small coefficient of thermal expansion when the temperature changes, and at the same time, it has strong resistance to chemical substances and is not easily corroded. It is a preferred material for attaching a conductive heating layer.

[0028] Optionally, in some embodiments, the conductive element 12 or the electrode layer can be made of one of the following materials with good conductivity: gold, silver, copper, aluminum, tin, etc. Preferably, the electrode layer is laid with silver paste made of silver material. Silver paste has high conductivity, can effectively conduct current, reduce power loss, and silver paste is easy to form on the surface of the heating element 11, which is convenient for processing and production. Preferably, the conductive element 12 is made of silver material to form a silver ring structure. When the conductive element 12 is pressed against the electrode layer by external force, it can enhance the stability of the continuous conduction of the circuit.

[0029] Optionally, in some embodiments, the first clamping member and / or the second clamping member may be made of non-conductive materials such as rubber, silicone, or plastic. Preferably, the first clamping member and / or the second clamping member are made of high-temperature resistant plastic material. Plastic is easy to manufacture and has low manufacturing cost. It has a certain structural strength and a certain elasticity, and is suitable for continuously clamping and pressing the conductive member 12 without losing its elasticity.

[0030] Optionally, in some embodiments, the nano-metal oxide or nano-semiconductor metal oxide may be made of one or a combination of materials such as tin, antimony, nickel, and ammonium as nanoparticles. During fabrication, the nano-semiconductor metal oxide may be attached to the surface of the first through hole by one of the following methods: physical vapor deposition (PVD), chemical vapor deposition (CVD), screen printing (SS), far-infrared spectroscopy (FI).

[0031] Example 1:

[0032] like Figures 1 to 5 The heating element mounting structure shown includes a heating component 1 and a clamping component 2 for detachably mounting the heating component 1. The heating component 1 includes a heating element 11 for heating when energized and a conductive element 12 for connecting to an external power source. The clamping component 2 elastically clamps the conductive element 12 so that the conductive element 12 presses against the heating element 11, and at least two conductive elements 12 respectively contact the electrode surfaces 111 at different positions of the heating element 11.

[0033] More specifically, in this embodiment, the heating component 1 is a core heating element used for generating heat when energized. The heating element 11 includes at least two non-overlapping electrode surfaces 111. The electrode surfaces 111 can be two or more, including three, four, or five. In this embodiment, it is preferable to have two electrode surfaces 111. The electrode surfaces 111 can be parallel or non-parallel. In this embodiment, it is preferable to have two non-overlapping and parallel electrode surfaces 111. A plurality of through-holes 112 are provided between the two electrode surfaces 111. In this embodiment, the plurality of through-holes 112 are arranged parallel to each other, and the through-holes 112 extend through the heating element 11 to supply external heat. The passage of airflow allows for minimal structural resistance, improving airflow smoothness and uniformity of heating, thus enhancing the overall airflow effect. Furthermore, each electrode surface 111 has an electrode layer for connecting to an external power source. This external power source provides electricity to the conductive heating layer. The electrode layers are laid on the electrode surfaces 111 and connected to the heating through-holes 112 (the conductive heating layer can be connected in series or parallel), forming the two electrode surfaces 111 as the two ends of the conductive heating layer. Once the electrode layers are connected to the external power supply, the conductive heating layer between the two electrode layers is energized, and the conductive heating layer begins to heat up, achieving the desired heating effect.

[0034] More specifically, in this embodiment, the conductive element 12 is a connecting accessory used to assist the electrode surface 111 of the heating element 11 in connecting to an external power source. The conductive element 12 has a contact portion that is concave and bent towards the electrode surface 111 on one side. An air passage is opened in the middle region of the conductive element 12 at the position of the corresponding heating through hole 112. All heating through holes 112 are located within the diameter range of the air passage to avoid affecting the smoothness of airflow through the heating through hole 112. On this basis, the clamping assembly 2 has an air passage corresponding to the position of the air passage to further avoid affecting the smoothness of airflow through the heating through hole 112. The clamping assembly 2 is a clamping component used to be assembled on the outside of the heating element 11 and the conductive element 12 and to implement elastic clamping and pressing action. By continuously generating elastic pressing and clamping effect on the conductive element 12 through the clamping assembly 2, the conductive element 12 is continuously and tightly in contact with the surface of the electrode surface 111, forming a good and stable contact connection structure, which helps to maintain the stability of continuous circuit conduction and avoids the situation of sparking or circuit interruption caused by poor contact.

[0035] More specifically, in this embodiment, the conductive heating layer is formed by one of the following materials: nano-metal oxide, nano-semiconductor metal oxide, graphene, carbon paste, etc., to form a planar heating layer. Preferably, nano-semiconductor metal oxide is used and is attached to the surface of the first through hole 12 by physical vapor deposition (PVD). The nano-semiconductor metal oxide has a very small attachment thickness and excellent electrical and thermal conductivity, which can generate heat evenly, further reduce power loss, and further concentrate the heat generation in the space inside the heating through hole 112, reducing heat loss and ineffective heating.

[0036] In use, the electrode layer is connected to an external power source to form an electrical circuit with the conductive heating layer. After the conductive heating layer is energized, it generates heat, which heats the airflow flowing through the heating hole 112, thereby achieving the heating effect.

[0037] As another embodiment 101 of embodiment 1, the conductive heating layer of this embodiment can also use graphene film as the conductive heating material. Graphene has a high thermal conductivity and excellent electrical conductivity. During manufacturing, the graphene film is formed on the surface of the heating through hole 112 to form a fixed heating area.

[0038] As another embodiment 102 of embodiment 1, the electrode surfaces 111 may also be non-parallel (not shown). When the electrode surfaces 111 are non-parallel, the heating element 11 will have a curved conduction path shape. This shape will cause the airflow to turn during the process of passing through when guiding the airflow. Moreover, this curved structure can also be used to attach nano-semiconductor metal oxides by physical vapor deposition, which is suitable for some heating scenarios that are not straight and need to bend.

[0039] In another embodiment 103 of embodiment 1, the cross-sectional shape of the heating through hole 112 can be a polygon (not shown) formed by straight lines, such as a triangle, quadrilateral, pentagon, hexagon, octagon, etc. It is preferred to use a hexagon as the cross-sectional shape of the heating through hole 112, which can make the arrangement more regular and compact, and also has good resistance to deformation under stress.

[0040] As another embodiment 104 of embodiment 1, the cross-sectional shape of the heating through hole 112 can be a curved shape (not shown) formed by a curve, such as a circle, an ellipse or one of the other shapes.

[0041] As another embodiment 105 of embodiment 1, the cross-sectional shape of the heating through hole 112 can be a shape formed by straight lines and curves (not shown), such as a long strip-shaped groove, a quadrilateral with rounded corners, etc.

[0042] Example 2:

[0043] Based on Example 1, such as Figures 1 to 5 The heating element mounting structure shown includes a clamping assembly 2 comprising a first clamping member 21 and a second clamping member 22 with a hollow through-structure. The first clamping member 21 and the second clamping member 22 are detachably connected (using one of the following methods: magnetic connection, spiral connection, snap-fit ​​connection, etc.) and press the conductive member 12 from the outside inward, so that the conductive member 12 is in close contact with the electrode surface 111. In this embodiment, the conductive member 12 is manufactured by a bending process to form an elastically deformable characteristic. When the first clamping member 21 and the second clamping member 22 press the conductive member 12 from the outside towards the heating element 11, the conductive member 12 undergoes elastic deformation and contacts the electrode surface 111, forming a close contact circuit conduction effect.

[0044] More specifically, in this embodiment, the first clamping member 21 has a first through hole 212 corresponding to the position of the heating through hole 112, and the second clamping member 22 has a second through hole 222 corresponding to the position of the heating through hole 112. When clamped, the first through hole 212, the heating through hole 112 and the second through hole 222 are connected in sequence to ensure the smooth flow of the airflow and facilitate user use.

[0045] As another embodiment 201 of embodiment 2, such as Figure 4 and Figure 5As shown, in this embodiment, the first clamping member 21 and the second clamping member 22 use an elastic deformable member 23 to press against the conductive member 12 as a way to implement elastic clamping. The clamping assembly 2 includes an elastic deformable member 23 for elastically clamping the conductive member 12. The elastic deformable member 23 is installed between the first clamping member 21 and the second clamping member 22 at the position for clamping the conductive member 12, so that either the first clamping member 21 or the second clamping member 22 can elastically press against the conductive member 12 through the elastic deformable member 23, so that the conductive member 12 is in close contact with the electrode surface 111, ensuring the tightness of the contact and ensuring the stability of the circuit conduction. In this embodiment, the elastic deformable member 23 is preferably a spring.

[0046] As another embodiment 203 of embodiment 201, such as Figure 6 As shown, the elastic deformable member 23 in this embodiment is an annular concave-convex elastic ring. The elastic deformable member 23 adopts a curved strip structure with the ends connected. The surface of the elastic deformable member 23 has adjacent concave curved surfaces and convex curved surfaces. The thickness of the elastic deformable member 23 is within the range of ±5mm of the thickness of the conductive member 12. The elastic deformable member 23 is located between the second clamping member 22 and the conductive member 12, so as to press the conductive member 12 to make stable contact with the heating element 11.

[0047] As another embodiment 202 of embodiment 2, the first clamping member 21 and the second clamping member 22 of this embodiment use a snap-fit ​​connection to lock the outside of the conductive member 12 as a way to implement elastic clamping. The conductive member 12 of this embodiment is made by bending process to form a characteristic that can be elastically deformed.

[0048] More specifically, the outer surface of the first clamping member 21 protrudes outward to form a first buckle 211 for engaging the second clamping member 22. The first buckle 211 extends a first buckle edge a along the through direction of the hollow through structure. The end of the first buckle edge a extends circumferentially around the center of the first clamping member 21 to form a second buckle edge b for restricting the axial installation position of the first clamping member 21. The first buckle edge a and the second buckle edge b form an L-shaped protrusion structure of the first buckle 211. At least two first buckles 211 are spaced apart circumferentially around the center of the first clamping member 21 to form a claw structure with uniform force.

[0049] More specifically, the inner surface of the second clamping member 22 protrudes towards the inner center and extends to form a second latch 221 for engaging the first clamping member 21. The second latch 221 has a third latching edge c extending circumferentially around the center of the second clamping member 22. At least two second latches 221 are spaced apart circumferentially around the center of the second clamping member 22. The first latch 211 and the second latch 221 are engaged to restrict the axial installation position of the first clamping member 21 relative to the second clamping member 22.

[0050] In use, the second buckle b of the first buckle 211 passes through the position between two adjacent third buckles c and the first buckle a is moved toward the third buckle c by screwing the first clamp 21 until the second buckle b contacts the third buckle c and the screwing stops. At this time, the first buckle 211 and the second buckle 221 are engaged (tightened or locked). The third buckle c restricts the axial movement of the second buckle b, so that the installation position between the first clamp 21 and the second clamp 22 is relatively stable.

[0051] As another embodiment 203 of embodiment 2, the conductive member 12 of this embodiment extends outward to the outside to facilitate the connection of a power cord to the power supply end 123. The conductive member 12 includes a first conductive member 121 and a second conductive member 122. The connection end 123 of the first conductive member 121 and the connection end 123 of the second conductive member 122 both pass through the clamping assembly 2 to connect to the external power supply.

[0052] More specifically, the first clamping member 21 and / or the second clamping member 22 are provided with clearance openings 25 for the extension of the power supply end 123. The first conductive member 121 and the second conductive member 122 are respectively installed on the electrode surfaces 111 at different positions of the heating element 11. During clamping, the first clamping member 21 presses the first conductive member 121 on one electrode surface 111 of the heating element 11, and the second conductive member 122 presses the second conductive member 122 on the other electrode surface 111 of the heating element 11. The first conductive member 121 and the second conductive member 122 are pressed tightly onto the heating element 11 by a snap-fit ​​connection, forming a stable and tight connection effect, which helps to ensure the stable conduction of the heating circuit and avoids phenomena such as sparking or poor contact.

[0053] Example 3:

[0054] Based on any of the above embodiments, such as Figures 1 to 5 The hot air device shown includes a fan 3 for air outlet, a fixed bracket 4 for mounting the fan 3, and a heating element mounting structure that is connected to and mounted on the fixed bracket 4. The fan 3 is the air output device of the hot air device. The fixed bracket 4 is used to stabilize the installation position of the fan 3 so that the air outlet of the fan 3 can be stably aligned with the heating element 11 of the heating element mounting structure. After the air is outleted, the airflow can flow through the heating through hole 112 that is heating up. The airflow is heated as it passes through to form hot air, which is then output for user use.

[0055] More specifically, the first clamping member 21 and the second clamping member 22 of the clamping assembly 2 elastically clamp and fix the air duct housing 43 of the bracket 4. The air duct housing 43 has a housing flange extending outward for clamping on the side near the heating element 11. One of the first clamping member 21 and the second clamping member 22 is fastened to the housing flange, so that the air duct housing 43 can elastically press against the conductive member 12. The conductive member 12 is pressed and contacts the electrode surface 112, forming a stable and tight contact to satisfy the circuit connection.

[0056] When in use, turn on the external power supply and start the fan 3 to rotate and output air. At the same time, connect the heating circuit of the heating element 11 so that the heating element 11 can heat up immediately. The air outlet of the fan 3 outputs air force to form an airflow towards the heating element 11. When the airflow passes through the heating through hole 111, it is affected by the heating of the conductive heating layer to form hot air. The hot air is then output to the outside for the user. The fan 3 may generate mechanical vibration during operation. These mechanical vibrations are weakened by the elastic clamping of the clamping component 2 during transmission, which reduces the associated vibration on the heating component 1 and reduces the positional deviation of the conductive component 12 relative to the heating element 11.

[0057] As another embodiment 301 of embodiment 3, the flange of the air duct housing 43 is provided with a flange groove for limiting the elastic deformation member 23 near the clamping component 2. Before clamping, the elastic deformation member 23 is placed in the flange groove, and then the heating component 1 is placed into the air duct housing 43. After the second clamping member 22 is sleeved into the fixed bracket 4, the first clamping member 21 and the second clamping member 22 are used to elastically clamp the heating component 1 and the fixed bracket 4 from both sides of the axial direction toward the heating body 11 through the elastic deformation member 23, so that the fixed bracket 4 presses the conductive member 12 at the position of the electrode surface 112 and stabilizes the installation position of the fixed bracket 4 relative to the heating component 1.

[0058] As another embodiment 302 of embodiment 3, the fixed bracket 4 includes a first housing 41 and a second housing 42. The first housing 41 and the second housing 42 are installed in a detachable manner (snap-fit ​​connection or screw connection) to stably clamp the fan 3, thereby limiting the installation position of the fan 3 on the fixed bracket 4 and facilitating disassembly, maintenance and production installation.

[0059] Example 4:

[0060] Based on Example 3, such as Figures 1 to 3 as well as Figure 5The hot air device shown includes a temperature sensor 5 for detecting the heating temperature of the heating element 11. The temperature sensor 5 can be one of a snap-action thermostat, a fuse, an NTC thermistor, or a thermocouple. A sensor positioning structure 24 extends outward from the surface of the clamping assembly 2 to limit the installation position of the temperature sensor 5. The sensor positioning structure 24 is a protruding shell structure formed on the first clamping member 21. The sensor positioning structure 24 has an installation inlet for the temperature sensor 5 to extend into and a detection port communicating with the hollow through-structure of the first clamping member 21. The temperature sensor 5 enters the device through the installation inlet. After the sensor positioning structure 24 is in place, the detection end of the temperature sensor 5 is close to the heating element 11. The temperature sensor 5 collects the temperature change data of the heating element 11 after it is heated. This data can be used by the user for reference and timely adjustment of the heating temperature of the hot air device, making it convenient for the user. On this basis, the temperature sensor 5 can be connected to the circuit between the heating component 1 and the external power supply. The heating circuit can be controlled by the temperature sensor 5 to affect the heating range and heating temperature of the heating element 11, realize automatic adjustment of temperature changes, avoid the heating element 11 overheating and burning the user or causing user discomfort during use, and make it convenient for the user.

[0061] In another embodiment 401 of embodiment 4, the hot air device is equipped with a control unit for controlling temperature changes. The temperature sensor 5 is electrically connected to the control unit and transmits the detected temperature change data back to the control unit. The control unit controls and adjusts the heating circuit to realize automatic temperature adjustment, avoids the heating element 11 from overheating and burning the user or causing discomfort to the user, and makes it convenient for the user to use.

[0062] The above examples are merely illustrative of the technical content of this utility model to facilitate reader understanding, but do not imply that the implementation of this utility model is limited to these embodiments.
