Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to an air outlet device and a heating device. Background Technology

[0002] Electric heaters, heater fans, and other common household heating devices are usually equipped with air outlets to deliver hot air. Existing air outlets that deliver hot air heat the incoming air through a heating element. The heating element is an important component to ensure the normal operation of the equipment. However, in the actual assembly process, improper wiring of the heating element can cause the wires to be damaged due to high temperature, and even cause safety hazards. Utility Model Content

[0003] In view of this, the present invention provides an air outlet device and a heating device to solve the problem that the wiring of the heating element in the existing air outlet device is unreasonable, which leads to the wires being easily damaged by high temperature.

[0004] In a first aspect, this utility model provides an air outlet device, comprising:

[0005] Heating components, including a heating element and wires;

[0006] The air guide assembly includes an air inlet plate and a volute tongue. The air inlet plate is disposed outside the heating body to guide the air intake, and the volute tongue is installed on the outer wall of the air inlet plate on the side away from the heating body.

[0007] A wiring channel, separated from the air inlet plate, is formed inside the volute tongue. One end of the wire is connected to the heating element, and the other end runs along the wiring channel.

[0008] Beneficial Effects: By routing the wires connected to the heating element to the outside of the air inlet plate, the air inlet plate acts as a primary heat insulation barrier, providing a certain degree of heat insulation. Furthermore, the wiring channel formed within the volute, separated from the air inlet plate, acts as a secondary heat insulation barrier, providing double insulation. This effectively prevents wire damage due to high temperatures, greatly improving product safety and reliability. It solves the problem of unreasonable wiring routing of the heating element in existing air outlet devices, which easily leads to wire damage due to high temperatures. In addition, this application installs the volute on the air inlet plate, placing the wiring within the volute's wiring channel. The volute separates the wires from the air inlet plate, achieving a heat insulation effect. This allows the volute to also function as a wire guide, offering multiple uses without requiring additional wiring structures, simplifying the structure and saving costs.

[0009] In one alternative embodiment, the heating assembly further includes:

[0010] The temperature limiter is installed on the side of the air inlet plate away from the heating element, and the heating element and the temperature limiter are connected in series by wires.

[0011] The cable routing channel has cable passage openings at both ends, and the cable routing channel includes a first cable routing sidewall and a second cable routing sidewall that are arranged opposite to each other;

[0012] The first wiring sidewall is separated between the air inlet plate and the wiring channel, and an avoidance opening is provided on the first wiring sidewall corresponding to the position of the temperature limiter.

[0013] Beneficial Effects: The temperature limiter ensures that the heating element's temperature remains within the set range, improving safety. During assembly, the temperature limiter is first installed on the air inlet plate, then the wiring between the heating element, temperature limiter, and external circuit is connected. The volute is then assembled onto the air inlet plate from top to bottom. The first wiring sidewall is inserted between the wire and the air inlet plate, effectively isolating the wire and providing heat insulation. A clearance opening corresponding to the temperature limiter is provided on the first wiring sidewall near the air inlet plate in the wiring channel, allowing for easier assembly of the volute. Since the space within the wiring channel is limited and wiring is inconvenient, this application installs the temperature limiter on the air inlet plate instead of directly into the wiring channel, making wiring easier. By optimizing the assembly process of the temperature limiter, volute, and air inlet plate, as well as the wiring path of the heating element's wires, the assembly method of the heating element and temperature limiter is more rational, effectively preventing wire damage due to high temperatures and improving the safety, reliability, and service life of the equipment. By forming a wiring channel by enclosing the second wiring sidewall with the first wiring sidewall, the wiring can not only be protected from scratches and damage to other components, but also the wiring can be hidden, resulting in a better aesthetic appearance.

[0014] In one alternative embodiment, the air inlet plate includes a first air guide section located on the side of the heating element;

[0015] The volute tongue is installed on the outside of the first air guide section, the cable channel has a cavity with a top opening, and the clearance is a notch structure opened on the side wall of the first cable channel.

[0016] The cabling channel also includes two cabling end walls that are set opposite each other, with the cabling openings located on the cabling end walls.

[0017] Beneficial effects: The air inlet plate includes a first air guide section located on the side of the heating element. The temperature limiter is installed on the outer wall of the first air guide section. The volute is installed on the outer side of the first air guide section from bottom to top. The clearance opening adopts a notch form and extends through the top edge of the first wiring side wall, so that the first wiring side wall will not interfere with the temperature limiter when the volute is assembled. The wire passage also adopts a notch form and extends through the top edge of the wiring end wall, making it easier to put the wire into the wiring channel or take it out of the wiring channel.

[0018] In one alternative implementation, the volute is detachably mounted on the air intake plate.

[0019] Beneficial effects: The volute tongue is detachably mounted on the air inlet plate, making it easy to install and remove.

[0020] In one alternative implementation, the volute tongue is inserted into and positioned with the air inlet plate and fixed with screws.

[0021] Beneficial effects: The volute tongue and the air inlet plate are positioned by plugging in, which can form a pre-position and improve assembly efficiency. The screw fixing can effectively ensure the stability and reliability of the connection between the volute tongue and the air inlet plate.

[0022] In one alternative implementation, the thermal conductivity of the volute tongue is less than that of the air inlet plate.

[0023] Beneficial effects: The volute is made of a material with a thermal conductivity lower than that of the air inlet plate, which can play a good role in heat insulation. The air inlet plate is made of a material with a relatively higher thermal conductivity, which has excellent high temperature resistance and will not melt, deform or be damaged even when heated by the heating element for a long time.

[0024] In one alternative embodiment, a wire is connected to the first end of the heating element, and the air outlet device further includes:

[0025] The mounting side plates are located at both ends of the heating element. The mounting side plates and the air inlet plate enclose a cavity to form a receiving cavity, and the heating element is placed inside the receiving cavity.

[0026] The mounting side plate includes a first mounting side plate, which is located at the first end of the heating element. The first mounting side plate is provided with a wire outlet hole and a wire inlet hole at intervals. The wire passes out from the wire outlet hole and then passes through the wire inlet hole into the wiring channel.

[0027] Beneficial effects: The first mounting side plate has an outlet hole and an inlet hole. The wire from the end of the heating element first passes through the outlet hole, goes around to the outside of the first mounting side plate, and then enters the wiring channel of the volute tongue through the inlet hole. Through the above design, the wire is placed on the outside of the first mounting side plate, so that the wire and the heating element are isolated by the first mounting side plate, ensuring that the wiring path is reasonable and safe. It effectively avoids the problem that the wire is easily damaged by high temperature when it runs from the inside of the first mounting side plate, which poses a high safety hazard.

[0028] Secondly, this utility model also provides a heating device, including the air outlet device of any of the above embodiments.

[0029] In one alternative embodiment, the heating device further includes:

[0030] The simulated flame assembly is installed above the air guide assembly and blocks the opening at the top of the wiring channel.

[0031] Beneficial effects: By installing the simulated flame component above the air guide component and sealing the opening at the top of the wiring channel, not only can the wiring be hidden and the aesthetics improved, but the heat insulation effect of the wiring channel can also be further improved.

[0032] In one alternative implementation, the heating device is a baseboard heater. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

[0063] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0064] Common household heating devices such as electric heaters and electric fan heaters rely heavily on their heating elements and thermostats for proper operation. However, in actual assembly, the wiring between the heating element and the thermostat often lacks effective insulation, leading to wire damage from high temperatures and even safety hazards. Furthermore, the assembly method of the heating element and thermostat directly affects the reliability and lifespan of the equipment. Therefore, proposing a reasonable assembly method and wiring insulation scheme is crucial.

[0065] This utility model aims to solve the problem of wire damage due to high temperature caused by unreasonable wiring of the heating element and lack of effective heat insulation measures, especially the problem of proper assembly and wiring insulation between the heating element and the temperature limiter. The specific technical problems to be solved are as follows:

[0066] 1. Improper wiring of the heating element leads to the wires being easily damaged due to high temperature;

[0067] 2. The wiring between the heating element and the temperature limiter lacks effective heat insulation measures, and the assembly method of the heating element and the temperature limiter is not reasonable, which affects the reliability and service life of the equipment.

[0068] The following is combined Figures 1 to 15 The following describes embodiments of the present invention.

[0069] According to an embodiment of the present invention, in one aspect, the present invention provides an air outlet device, including: a heating component and an air guiding component, such as... Figure 1 , Figure 2 As shown, the heating assembly includes a heating element 1 and a wire 2; Figures 4 to 8 As shown, the air guide assembly includes an air inlet plate 3 and a volute tongue 4. The air inlet plate 3 is disposed outside the heating element 1 to guide the air intake. The volute tongue 4 is installed on the outer wall of the air inlet plate 3 away from the heating element 1. A wiring channel 40 is formed inside the volute tongue 4, which is separated from the air inlet plate 3. One end of the wire 2 is connected to the heating element 1, and the other end runs along the wiring channel 40.

[0070] In the above embodiments, by routing the wire 2 connected to the heating element 1 to the outside of the air inlet plate 3, the air inlet plate 3 acts as a primary heat insulation barrier, providing a certain degree of heat insulation. Furthermore, the volute tongue 4, separated from the air inlet plate 3 by a wiring channel 40 formed within it, acts as a secondary heat insulation barrier, providing double heat insulation. This effectively prevents the wire 2 from being damaged by high temperatures, greatly improving the safety and reliability of the product. It solves the problem in existing air outlet devices where the unreasonable wiring of the heating element 1 leads to easy damage to the wire due to high temperatures. In addition, this application installs the volute tongue 4 on the air inlet plate 3, placing the wiring within the wiring channel 40 of the volute tongue 4. The volute tongue 4 separates the wire 2 from the air inlet plate 3, achieving a heat insulation effect. This allows the volute tongue 4 to also function as a wiring guide, serving multiple purposes without requiring additional wiring structures, simplifying the structure and saving costs.

[0071] Specifically, the volute tongue 4 is detachably mounted on the air inlet plate 3. Preferably, the volute tongue 4 is plugged into the air inlet plate 3. Since the air inlet plate 3 is closer to the heating element 1, the heat resistance of the air inlet plate 3 is much higher than that of the volute tongue 4. The volute tongue 4 is less likely to conduct heat than the air inlet plate 3, thus playing an effective role in heat insulation.

[0072] In this embodiment, the thermal conductivity of the volute tongue is lower than that of the air inlet plate. The volute tongue is made of a material with a lower thermal conductivity than the air inlet plate, which provides good heat insulation. The air inlet plate is made of a material with a relatively higher thermal conductivity, which has excellent high-temperature resistance and will not melt, deform, or be damaged even after being heated by the heating element for a long time.

[0073] Preferably, the volute 4 is a plastic part, and the air inlet plate 3 is a sheet metal part. The volute 4 is made of plastic, which is not only low in cost but also has low thermal conductivity, thus providing good heat insulation. The air inlet plate 3 is made of sheet metal, which has excellent high-temperature resistance and will not melt, deform, or be damaged even under prolonged heating.

[0074] Furthermore, combined Figure 15 As shown, the air inlet plate 3 is located at the air inlet of the whole machine, and an air inlet channel is formed inside the air inlet plate 3. The heating element 1 is located inside the air inlet channel. Preferably, the air inlet plate 3 includes an upper air inlet plate 301 and a lower air inlet plate 302, which together form an air inlet channel. In this embodiment, the volute tongue 4 and the temperature limiter 5 are both installed on the upper air inlet plate 301. The air inlet device also includes a fan wheel 8 and a volute 9. The volute tongue 4 and the volute 9 are spaced apart on the outer periphery of the fan wheel 8. The two ends of the volute tongue 4 and the volute 9 respectively form a fan wheel air inlet and a fan wheel air outlet. The outlet end of the air inlet channel is connected to the fan wheel air inlet. The volute tongue 4 is located above the fan wheel 8 and is assembled on the side of the upper air inlet plate 301.

[0075] Furthermore, wire 2 is connected to one end of heating element 1, and wire 2 is connected to the main circuit inside the whole machine, which can also be understood as being connected to the power supply. Wire 2 is the solder lead for the common terminal of heating element 1.

[0076] In some embodiments, combined with Figures 4 to 8 As shown, the heating assembly also includes a temperature limiter 5, which is installed on the side of the air inlet plate 3 away from the heating element 1. The wire 2 connects the heating element 1 and the temperature limiter 5 in series. The two ends of the wiring channel 40 are respectively provided with wire passage openings 400. The wiring channel 40 includes a first wiring sidewall 401 and a second wiring sidewall 402 arranged opposite to each other. The first wiring sidewall 401 is separated between the air inlet plate 3 and the wiring channel 40, and a clearance opening 4011 is provided on the first wiring sidewall 401 corresponding to the position of the temperature limiter 5.

[0077] In the above embodiment, the temperature limiter 5 ensures that the heating temperature of the heating element 1 is maintained within the set temperature range, improving safety. During assembly, the temperature limiter 5 is first installed on the air inlet plate 3, then the wiring between the heating element 1, the temperature limiter 5, and the external circuit is connected. The volute tongue 4 is then assembled onto the air inlet plate 3 from top to bottom. The first wiring sidewall 401 is inserted between the wire 2 and the air inlet plate 3, separating the wire 2 from the air inlet plate 3 and providing effective heat insulation. The clearance opening 4011 on the first wiring sidewall 401 near the air inlet plate 3, corresponding to the temperature limiter 5, allows for clearance of the temperature limiter 5, facilitating the assembly of the volute tongue 4. Because the space within the wiring channel 40 is relatively limited and inconvenient for wiring, this application mounts the temperature limiter 5 on the air inlet plate 3 instead of directly into the wiring channel 40, making it easier to wire the temperature limiter 5. By optimizing the assembly process of the temperature limiter 5, the volute 4, the air inlet plate 3, and the wiring path of the wire 2 of the heating element 1, the assembly method of the heating element 1 and the temperature limiter 5 is more reasonable, effectively preventing the wires from being damaged due to high temperature, and improving the safety, reliability, and service life of the equipment. The wiring channel is formed by the second wiring sidewall and the first wiring sidewall, which not only protects the wire 2 from scratches and damage to other components, but also hides the wire 2, resulting in better aesthetics.

[0078] Specifically, the first wiring sidewall 401 and the second wiring sidewall 402 extend along the length of the air inlet plate 3, and the wiring direction of the first wiring sidewall 401 and the second wiring sidewall 402 is consistent with the wiring direction of the wire 2. The temperature limiter 5 is installed on the outer wall of the air inlet plate 3. Preferably, there are two temperature limiters 5, which are spaced apart along the length of the air inlet plate 3. The wire 2 connects the heating element 1 and the two temperature limiters 5 in series to the external circuit.

[0079] Furthermore, the temperature limiter 5 includes a temperature limiter body 51 and a temperature limiter bracket 52. The temperature limiter body 51 is mounted on the temperature limiter bracket 52, and the temperature limiter bracket 52 is detachably mounted on the air inlet plate 3. Preferably, the temperature limiter 5 is connected to the air inlet plate 3 by snap-fit ​​and / or screws. The temperature limiter 5 has wiring terminals, and the wire 2 is provided with corresponding inserts to achieve plug-in connection. One end of the wire 2 is connected to the heating element 1, and the other end is connected to the two temperature limiters 5 in sequence through inserts and wiring terminals, and then connected to the electronic circuit of the whole machine to be connected to the power supply.

[0080] In this embodiment, the temperature limiter 5 is installed on the air inlet plate 3, and the wire 2 of the common end of the heating element 1 is plugged into the temperature limiter 5. At the same time, the two temperature limiters 5 and the temperature limiter 5 are electrically connected to the external circuit to ensure the reliability of the electrical connection. Specifically, the wire 2 includes a first segment connected between the heating element 1 and one of the temperature limiters 5, a second segment connected between the two temperature limiters 5, and a third segment connected between the other temperature limiter 5 and the main circuit.

[0081] In some embodiments, the air inlet plate 3 includes a first air guide section 31 located on the side of the heating element 1; the volute tongue 4 is installed on the outside of the first air guide section 31; the wiring channel 40 has a cavity with a top opening; the clearance opening 4011 is a notch structure opened on the first wiring side wall 401; the wiring channel 40 also includes two wiring end walls 403 arranged opposite to each other; the wiring port 400 is opened on the wiring end wall 403.

[0082] In the above embodiment, the air inlet plate 3 includes a first air guide section 31 located on the side of the heating element 1. The temperature limiter 5 is installed on the outer wall of the first air guide section 31. The volute tongue 4 is installed from bottom to top on the outer side of the first air guide section 31. The clearance opening 4011 adopts a notch form and penetrates the top edge of the first wiring side wall 401, so that when the volute tongue 4 is assembled, the first wiring side wall 401 will not interfere with the temperature limiter 5. The wire passage opening 400 also adopts a notch form and penetrates the top edge of the wiring end wall 403, making it more convenient for the wire 2 to be put into the wiring channel 40 or taken out from the wiring channel 40.

[0083] In some embodiments, the air inlet plate 3 further includes a second air guide section 32 located at the top of the heating element 1, the first air guide section 31 is vertically arranged, the second air guide section 32 is horizontally arranged, the air inlet plate 3 further includes an inclined air expansion section 33, the second air guide section 32 is connected between the first air guide section 31 and the air expansion section 33, and the air expansion section 33 is arranged at the air inlet.

[0084] In some embodiments, the volute 4 is detachably mounted on the air inlet plate 3.

[0085] In the above embodiment, the volute tongue 4 is detachably mounted on the air inlet plate 3, which facilitates disassembly and assembly.

[0086] Specifically, the volute tongue 4 can be installed and fixed on the air inlet plate 3 by means of snap-fit, screw connection 6, plug-in, etc.

[0087] In some embodiments, combined with Figure 6 and Figure 10 As shown, the volute tongue 4 is inserted into and positioned with the air inlet plate 3 and fixed by screws 6.

[0088] In the above embodiments, the volute tongue 4 and the air inlet plate 3 are positioned by plugging in, which can form a pre-position and improve assembly efficiency. The screws 6 are used for fixing, which can effectively ensure the stability and reliability of the connection between the volute tongue 4 and the air inlet plate 3.

[0089] Specifically, the air inlet plate 3 is provided with a socket 34, and the volute tongue 4 is provided with a connecting rib 41. During assembly, the connecting rib 41 is aligned with the socket 34, so that the volute tongue 4 is inserted into the air inlet plate 3 from bottom to top, so that the connecting rib 41 is inserted and limited in the socket 34, and then it is tightened by screw 6.

[0090] Furthermore, a protruding plate 35 is provided on the outer side wall of the air inlet plate 3, and an insertion hole 34 is provided on the protruding plate 35. Preferably, there are multiple insertion holes 34, which are spaced apart along the length direction of the air inlet plate 3. More preferably, insertion holes 34 are provided at both ends in the width direction of the air inlet plate 3, and multiple insertion ribs 41 are correspondingly provided on the volute tongue 4. The multiple insertion ribs 41 are spaced apart along the length direction of the volute tongue 4, and insertion ribs 41 are provided at both ends in the width direction of the volute tongue 4. Through the above design, the entire volute tongue 4 can fit tightly against the outer wall of the air inlet plate 3, and the structural stability is higher.

[0091] Furthermore, two sets of connecting holes are provided at both ends of the volute tongue 4 and the air inlet plate 3 along the length direction. The two sets of connecting holes are connected by two screws 6 to make the volute tongue 4 more securely and stably fixed on the air inlet plate 3.

[0092] In a specific example, there are five sets of protruding plates 35 and insertion holes 34, which are divided into upper and lower layers. The upper layer has two sets, which are located at both ends of the air inlet plate 3. The lower layer has three sets of protruding plates 35 and insertion holes 34, which are arranged at intervals along the length of the air inlet plate 3. More preferably, the five sets of protruding plates 35 and insertion holes 34 are staggered along the length of the air inlet plate 3. The volute tongue 4 is provided with five corresponding connecting ribs 41. The arrangement of the five connecting ribs 41 is the same as the arrangement of the five sets of protruding plates 35 and insertion holes 34, and will not be described again here.

[0093] In some embodiments, combined with Figures 1 to 4 , Figure 6 , Figure 11 and Figure 12 As shown, the wire 2 is connected to the first end of the heating element 1. The air outlet device also includes a mounting side plate, which is set at both ends of the heating element 1. The mounting side plate and the air inlet plate 3 enclose a cavity to form a receiving cavity, and the heating element 1 is set in the receiving cavity. The mounting side plate includes a first mounting side plate 7, which is located at the first end of the heating element 1. The first mounting side plate 7 is provided with a wire outlet hole 71 and a wire inlet hole 72 at intervals. The wire 2 passes through the wire outlet hole 71 and then through the wire inlet hole 72 into the wiring channel 40.

[0094] In the above embodiment, the first mounting side plate 7 has a wire outlet hole 71 and a wire inlet hole 72. The wire at the end of the heating element 1 first passes through the wire outlet hole 71, goes around to the outside of the first mounting side plate 7, and then enters the wiring channel 40 of the volute tongue 4 through the wire inlet hole 72. Through the above design, the wire 2 is placed on the outside of the first mounting side plate 7, so that the wire 2 and the heating element 1 are isolated by the first mounting side plate 7, ensuring that the wiring path is reasonable and safe, and effectively avoiding the problem that the wire 2 is easily damaged by high temperature when it runs from the inside of the first mounting side plate 7, which poses a high safety hazard.

[0097] Specifically, the heating device 10 includes a housing 11, an air outlet device is disposed inside the housing 11, the housing 11 is provided with an air inlet and an air outlet, the air inlet plate 3 of the air outlet device is disposed at the air inlet, an air inlet channel is formed inside the air inlet plate 3 connecting the air inlet and the air inlet of the impeller, the heating component is located inside the air inlet channel, and the air outlet of the impeller is connected to the air outlet of the housing 11.

[0098] In this embodiment, the heating device 10 includes, but is not limited to, electric heaters and electric fans.

[0099] Preferably, the heating device 10 is a skirting board electric heater.

[0100] In some embodiments, the heating device 10 further includes a simulated flame assembly 12, which is mounted above the air guide assembly and blocks the opening at the top of the wiring channel 40.

[0101] In the above embodiment, by installing the simulated flame component 12 above the air guide component and sealing the opening at the top of the wiring channel 40, not only can the wiring be hidden and the aesthetics improved, but the heat insulation effect of the wiring channel 40 can also be further improved.

[0102] Specifically, the simulated flame assembly 12 is installed above the upper air intake plate 301. The side wall of the simulated flame assembly 12 is inserted into the volute 4 and connected to the volute 4 and the upper air intake plate 301 respectively by screws 6. In this embodiment, the simulated flame assembly 12 includes a mist-emitting structure and a light-emitting structure. The mist-emitting structure can humidify the air, avoiding the problem of indoor dryness caused by long-term heating of the heating device 10. The light-emitting structure can illuminate the water mist sprayed by the mist-emitting structure, thereby forming a simulated flame effect with better visual effect.

[0103] In this embodiment, the assembly process of the air outlet device is as follows:

[0104] 1. Preparation stage: The common end of the heating element 1 is equipped with a wire 2 (i.e., a welding lead), and the first mounting side plate 7 has a wire outlet hole 71 and a wire inlet hole 72.

[0105] 2. Assembly of heating element 1: Place heating element 1 on the assembly platform. The common terminal wires first pass through the outgoing wire hole 71 and then through the incoming wire hole 72.

[0106] 3. Installation of temperature limiter 5: Install temperature limiter bracket 52 and temperature limiter 5 on air inlet plate 3, connect wire 2 of common end of heating element 1 to temperature limiter 5, and connect all wires of temperature limiter 5.

[0107] 4. Assembly of volute tongue 4: Insert and install volute tongue 4 onto air inlet plate 3 from bottom to top, and place the wiring from the previous step into the wiring channel 40 of volute tongue 4, separating it from air inlet plate 3.

[0108] 5. Assemble the simulated flame assembly 12: Assemble the upper simulated flame assembly 12 with the volute tongue 4, and place the wiring inside the cavity formed by the simulated flame assembly 12 and the wiring channel 40. The simulated flame assembly 12, the volute tongue 4, and the air inlet plate 3 form the air inlet plate 3 assembly.

[0109] 6. Overall assembly: Assemble the air inlet plate 3 assembly with the two mounting side plates, connect and tighten with screws 6, then install the heating element 1 onto the mounting side plates and tighten with screws 6.

[0110] The above methods enable optimized wiring routing for the heating element 1 and the temperature limiter 5, while also providing heat insulation for the internal wiring. By optimizing the assembly process and wiring path, damage to the wires due to high temperatures is effectively prevented, improving the safety and reliability of the equipment. This solves the problems of insufficient heat insulation measures for the wiring between the heating element 1 and the temperature limiter 5, as well as the unreasonable assembly method of the heating element 1 and the temperature limiter 5, which affected the reliability and service life of the equipment.

[0111] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the protection scope of the embodiments of this application.
