Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of the range, specifically, a burner and a range. BACKGROUND

[0002] With the use rate of gas range being higher and higher, people's requirement for the safety of the range is also higher and higher. The existing gas range is usually provided with a temperature sensing probe to detect the temperature of the pot, and to judge whether the burner is dry burning, accidental extinguishing or the like according to the detected temperature, so that the gas source can be cut off in the first time when the above-mentioned situations occur, to avoid safety hazards.

[0003] At present, most of the gas ranges on the market are provided with an external temperature sensing probe beside the fire cover, which senses the temperature of the bottom of the pot, and automatically extinguishes the flame when the temperature of the bottom of the pot exceeds the preset temperature; at the same time, when the range accidentally extinguishes the flame and the pot is not placed for a long time, the gas source can also be cut off in the first time based on the detection result of the external temperature sensing probe to avoid accidents.

[0004] However, the external temperature sensing probe has certain limitations in use, such as: because the external temperature sensing probe needs to be in contact with the bottom of the pot, in order to avoid interference with the external temperature sensing probe, only flat-bottomed pots can be used for cooking; in addition, the external temperature sensing probe is easily affected by the flame, which causes the external temperature sensing probe to be unable to accurately detect the temperature of the bottom of the pot, resulting in abnormal determination of the range to extinguish the flame. SUMMARY

[0007] The burner of the utility model can be in contact with the ejector pipe of the burner to directly measure the temperature of the ejector pipe, or be arranged on the bracket by the fastener and be in contact with the fastener to indirectly measure the temperature of the ejector pipe by measuring the temperature of the fastener. When the burner is used to heat the pot of the range, the temperature of the bottom of the pot can be transmitted to the ejector pipe, and the temperature of the bottom of the pot can be indirectly detected by sensing the temperature of the ejector pipe. In this way, not only is the direct contact between the temperature sensing piece and the pot avoided to prevent interference between the temperature sensing piece and the pot, so that the burner can be applied to different types of pots, but also the distance between the temperature sensing piece and the flame of the burner is avoided to be too close, so that the temperature sensing piece is not affected by the flame, the accuracy of the sensing result of the temperature sensing piece is effectively ensured, and the reliability and safety of the burner are improved.

DETAILED DESCRIPTION

[0041] In the following description, numerous specific details are provided in order to provide a thorough understanding of the present application. One of ordinary skill in the art will realize, however, that the application can be practiced without one or more of these details. In other instances, well-known features have not been described in detail in order not to unnecessarily obscure the present application.

[0042] In order to thoroughly understand the embodiments of the present application, detailed structures will be presented in the following description. Obviously, the implementation of the embodiments of the present application is not limited to the special details familiar to those skilled in the art. The preferred embodiments of the present application are described in detail as follows, however, in addition to these detailed descriptions, the present application can also have other embodiments.

[0043] In one embodiment of the utility model, a furnace head 10 is provided, which can avoid direct contact between the temperature sensing element 130 and the pot, improve the applicability of the furnace head 10, and improve the reliability and safety of the furnace head 10. In the following, a furnace head 10 according to the embodiment of the utility model will be described in detail in combination with the drawings.

[0044] In combination with reference to Figure 2 and Figure 1 , the furnace head 10 includes an ejector pipe 110, a bracket 120 and a temperature sensing element 130, and the ejector pipe 110 is positioned by the bracket 120. The temperature sensing element 130 is in contact with the ejector pipe 110. The temperature sensing element 130 is connected to the bracket 120 by a fastener 140, and the temperature sensing element 130 is in contact with the fastener 140.

[0045] Specifically, the number and type of the ejector pipe 110 can be determined according to the type of the furnace head 10. For example, Figure 1 , the furnace head 10 shown in Figure 1 is a double-ring fire furnace head 10, when the furnace head 10 is a double-ring fire furnace head 10, the ejector pipe 110 can include an inner ring ejector pipe 1105 and an outer ring ejector pipe 1106. When the furnace head 10 is a three-ring fire furnace head 10, the ejector pipe 110 can include an inner ring ejector pipe 1105, a middle ring ejector pipe and an outer ring ejector pipe 1106. The temperature sensing element 130 can be attached to one or more of the above ejector pipes 110, preferably attached to the inner ring ejector pipe 1105.

[0046] Specifically, one end of the ejector pipe 110 can be in communication with the gas source, the other end of the ejector pipe 110 can be provided on the bracket 120, and the temperature sensing element 130 can be directly attached to the ejector pipe 110 or the fastener 140. In this way, when the furnace head 10 is in a burning state, the heat generated can be transmitted to the ejector pipe 110 or through the ejector pipe 110 to the bracket 120, and then to the fastener 140 by the bracket 120, and the temperature sensing element 130 attached to the ejector pipe 110 or the fastener 140 can sense the temperature of the ejector pipe 110.

[0047] Further, the bracket 120 can be made of a heat-conducting material, such as metal or other materials with good heat transfer performance. The ejector pipe 110 can also be made of a heat-conducting material, such as metal or other materials with good heat transfer performance. The bracket 120 and the ejector pipe 110 can be made of the same material, such as stainless steel, so that the bracket 120 and the ejector pipe 110 form a stainless steel assembly.

[0048] Again in combination with reference to Figure 2 , Figure 3 and Figure 13The bracket 120 can have a plate body 1201 and a leg 1202. One end of the leg 1202 can be arranged on the plate body 1201. The end of the leg 1202 away from the plate body 1201 can form a connecting end 1203. In combination with reference to Figure 1 When the burner head 10 is applied to the stove 30, the connecting end 1203 can be fixedly connected to the bottom shell 310 of the stove 30 to realize the fixation of the burner head 10. The ejector pipe 110 can be at least partially arranged in the plate body 1201. In this way, the positioning of the ejector pipe 110 is facilitated, and since the temperature of the bottom of the pot above the burner head 10 is transmitted to the ejector pipe 110 or the fastener 140 in the case of heating the pot, the temperature of the ejector pipe 110 or the fastener 140 is associated with the temperature of the bottom of the pot, thereby ensuring the accuracy and rapidity of temperature sensing. Specifically, the plate body 1201 can be made of a material with good thermal conductivity such as stainless steel.

[0049] In combination with reference to Figure 2 , Figure 3 and Figure 8 , the temperature sensing element 130 can be located below the bracket 120, thereby not only avoiding the interference of the temperature sensing element 130 with the heat generated by the flame of the burner head 10, but also ensuring the overall aesthetics of the burner head 10.

[0050] In combination with reference to Figure 9 and Figure 3 , the temperature sensing element 130 can form a through hole 1301e, and the fastener 140 can pass through the through hole 1301e to be connected with the bracket 120. The fastener 140 can be a bolt or a screw, and the present application does not make a specific limitation thereon.

[0051] The burner head 10 of the present application can have the temperature sensing element 130 in contact with the ejector pipe 110 of the burner head 10 to directly measure the temperature of the ejector pipe 110, or arranged on the bracket 120 through the fastener 140 and in contact with the fastener 140 to indirectly measure the temperature of the ejector pipe 110 by measuring the temperature of the fastener 140. When the burner head is applied to the stove to heat the pot, since the temperature of the bottom of the pot can be transmitted to the ejector pipe 110, the temperature of the bottom of the pot can be indirectly detected by sensing the temperature of the ejector pipe 110. In this way, not only is the direct contact between the temperature sensing element 130 and the pot avoided to prevent interference between the temperature sensing element 130 and the pot, thereby making the burner head 10 applicable to different types of pots, but also the distance between the temperature sensing element 130 and the flame of the burner head 10 is avoided to be too close, thereby avoiding the temperature sensing element 130 being affected by the flame, effectively ensuring the accuracy of the sensing result of the temperature sensing element 130, and further improving the reliability and safety of the burner head 10.

[0052] In some embodiments, in combination with reference to Figure 4 , Figure 5 , Figure 6 andFigure 3 The injection pipe 110 has a pipe body 1101 and a positioning boss 1104 protruding from the outer wall surface of the pipe body 1101, and the pipe body 1101 is divided into an upper pipe segment 1102 and a lower pipe segment 1103 by the positioning boss 1104. The temperature sensing member 130 has a heat conduction part 1301, at least a part of which is in contact with the upper pipe segment 1102 and / or at least a part of which is in contact with the lower pipe segment 1103. In this way, the heat conduction part 1301 of the temperature sensing member 130 can be in contact with one or more of the upper pipe segment 1102 or the lower pipe segment 1103, so as to sense the temperature change of the injection pipe 110 in real time, thereby avoiding the direct contact between the heat conduction part 1301 and the pot, and affecting the accuracy of the sensing result, and determining the temperature change of the pot bottom through the temperature change of the injection pipe 110, and effectively improving the accuracy of the sensing result of the temperature sensing member 130 and the safety of the stove head 10.

[0053] Specifically, the positioning boss 1104 can be arranged on the support 120, and the pipe body 1101 can pass through the positioning boss 1104 and be arranged on the support 120. The positioning boss 1104 can position the installation position of the pipe body 1101, thereby simplifying the installation steps of the injection pipe 110 and reducing the possibility of installation errors.

[0054] The heat conduction part 1301 can transmit the sensed temperature to the temperature sensing member 130, and then the temperature sensing member 130 determines the sensed temperature information. Specifically, the heat conduction part 1301 can be made of copper or aluminum or other materials with good heat conductivity. The material of the heat conduction part 1301 is not limited in the present application, and any material with good heat conductivity can be used.

[0055] Further, the heat conduction part 1301 can be in the shape of a plate. The plate-shaped heat conduction part 1301 can be tightly attached to the upper pipe segment 1102 or the lower pipe segment 1103, thereby quickly and efficiently transmitting the heat of the upper pipe segment 1102 or the lower pipe segment 1103 to the temperature sensing member 130. In this way, the loss and delay in the heat transmission process are greatly reduced, and the temperature sensing member 130 can obtain more accurate temperature information.

[0056] Again referring to Figure 4 and Figure 5 The heat conduction part 1301 of the temperature sensing member 130 can be in contact with the upper pipe segment 1102 of the pipe body 1101. Since the upper pipe segment 1102 is closer to the pot, the heat generated by the pot heated by the stove head 10 is more likely to be transmitted to the upper pipe segment 1102, and thus the temperature information sensed by the temperature sensing member 130 is more rapid and direct. Again referring to Figure 6 and Figure 4The heat-conducting part 1301 of the temperature sensing element 130 can also be in contact with the lower pipe section 1103 of the pipe body 1101, which is farther away from the pot than the upper pipe section 1102. The temperature sensing element 130 in contact with the lower pipe section 1103 is less likely to be disturbed by the heat generated by the flame, so the temperature information sensed by the temperature sensing element 130 is more accurate. Of course, the heat-conducting part 1301 of the temperature sensing element 130 can also be in contact with both the upper pipe section 1102 and the lower pipe section 1103 of the pipe body 1101, so as to more comprehensively sense the temperature of the pipe body 1101.

[0057] In some embodiments, referring to Figure 5 The upper pipe section 1102 has an inner pipe part 1102a and a sleeve part 1102b, the sleeve part 1102b being sleeved outside the inner pipe part 1102a. The heat-conducting part 1301 has a heat-conducting surface 1301a, which is in surface contact with the outer surface of the sleeve part 1102b. In this way, the heat-conducting surface 1301a of the heat-conducting part 1301 can be in direct surface contact with the outer surface of the sleeve part 1102b, which not only ensures that the temperature sensing element 130 can sense the temperature of the ejector pipe 110, but also simplifies the connection mode between the temperature sensing element 130 and the ejector pipe 110. When the temperature sensing element 130 needs to be repaired or replaced, the temperature sensing element 130 can be conveniently disassembled, effectively improving the convenience of the operator.

[0058] The shape of the heat-conducting part 1301 can be adapted to the outer contour of the sleeve part 1102b. Specifically, the shape of the heat-conducting part 1301 can be arc-shaped plate-shaped, so as to not only have sufficient contact area between the heat-conducting part 1301 and the sleeve part 1102b, but also ensure that the two are closely attached.

[0059] The heat-conducting surface 1301a of the heat-conducting part 1301 and the outer surface of the sleeve part 1102b can be in contact through bonding connection or clamping connection, and the like. The application does not make specific limitations on the contact mode between the heat-conducting surface 1301a of the heat-conducting part 1301 and the outer surface of the sleeve part 1102b.

[0060] In some embodiments, referring to Figure 5The upper pipe segment 1102 has an inner pipe portion 1102a and a sleeve portion 1102b, the sleeve portion 1102b is sleeved outside the inner pipe portion 1102a, and the sleeve portion 1102b and the inner pipe portion 1102a have a receiving groove 1102c therebetween, and the heat conduction portion 1301 is arranged in the receiving groove 1102c. In this way, the heat conduction portion 1301 can be arranged in the receiving groove 1102c between the sleeve portion 1102b and the inner pipe portion 1102a, the sleeve portion 1102b can apply a force to the heat conduction portion 1301, so that the heat conduction portion 1301 can be closely attached in the receiving groove 1102c, effectively ensuring the firmness of the connection between the temperature sensing element 130 and the ejector pipe 110. Moreover, by arranging the receiving groove 1102c, the outer diameter of the ejector pipe 110 can be avoided to be increased, effectively ensuring the manufacturing cost of the ejector pipe 110.

[0061] Again referring to Figure 6 , the outer side wall of the inner pipe portion 1102a can be inwardly recessed to form the receiving groove 1102c, the depth of the receiving groove 1102c can be adapted to the thickness of the heat conduction portion 1301, and the shape of the receiving groove 1102c can be adapted to the shape of the heat conduction portion 1301, so that the heat conduction portion 1301 can be embedded in the receiving groove 1102c.

[0062] In an embodiment not shown, the inner side wall of the sleeve portion 1102b can be outwardly recessed to form the above-mentioned receiving groove 1102c.

[0063] In some embodiments, the heat conduction portion 1301 is formed with a heat conduction surface 1301a, the heat conduction surface 1301a is in surface contact with the inner surface of the sleeve portion 1102b; or / and, the heat conduction surface 1301a is in surface contact with the outer surface of the inner pipe portion 1102a. In this way, the temperature sensing element 130 can flexibly sense the temperature of the sleeve portion 1102b or the temperature of the inner pipe portion 1102a, so as to determine the temperature of the ejector pipe 110, further improving the flexibility and applicability of the temperature sensing element 130.

[0064] In an embodiment not shown, the heat conduction surface 1301a can be in surface contact with the outer surface of the sleeve portion 1102b, or can be in surface contact with the inner surface of the inner pipe portion 1102a.

[0065] In some embodiments, referring to Figure 7 and Figure 6The heat conduction part 1301 is formed with a heat conduction surface 1301a, which is in surface contact with the outer surface of the lower pipe section 1103. In this way, the heat conduction surface 1301a of the heat conduction part 1301 can be in direct surface contact with the outer surface of the lower pipe section 1103, which not only ensures that the temperature sensing element 130 can sense the temperature of the ejector pipe 110, but also simplifies the connection between the temperature sensing element 130 and the ejector pipe 110. When the temperature sensing element 130 needs to be repaired or replaced, the temperature sensing element 130 can be conveniently disassembled, effectively improving the convenience of use for the operator.

[0066] The shape of the heat conduction part 1301 can be adapted to the outer contour of the lower pipe section 1103. Specifically, the shape of the heat conduction part 1301 can be arc-shaped plate-shaped, which not only allows the heat conduction part 1301 to have sufficient contact area with the lower pipe section 1103, but also ensures that the two are closely attached. The heat conduction surface 1301a can be formed on the side of the heat conduction part 1301 that abuts against the outer surface of the lower pipe section 1103.

[0067] The heat conduction surface 1301a of the heat conduction part 1301 and the outer surface of the lower pipe section 1103 can be in contact through bonding or clamping connection, and the like. The application does not make specific limitations on the contact mode between the heat conduction surface 1301a of the heat conduction part 1301 and the outer surface of the lower pipe section 1103.

[0068] In some embodiments, referring to Figure 7 The lower pipe section 1103 includes a pipe body 1103a and an outer clamp 1103b, and at least part of the heat conduction part 1301 abuts against the outer surface of the pipe body 1103a through the outer clamp 1103b. In this way, the outer clamp 1103b can apply a force to the heat conduction part 1301, so that the heat conduction part 1301 can be closely attached to the outer surface of the pipe body 1103a, avoiding the situation that the two are detached, thereby effectively ensuring the firmness of the connection between the temperature sensing element 130 and the ejector pipe 110.

[0069] Specifically, the outer clamp 1103b can be sleeved on the pipe body 1103a and apply a force to the pipe body 1103a, or the outer clamp 1103b can be clamped with the pipe body 1103a, so as to attach the heat conduction part 1301 to the outer surface of the pipe body 1103a.

[0070] In some embodiments, referring to Figure 4A heat-conducting surface 1301a is formed on the heat-conducting part 1301, and the heat-conducting surface 1301a forms surface contact with the outer surface of the tube body 1103a. In this way, the heat-conducting surface 1301a of the heat-conducting part 1301 can directly contact the outer surface of the tube body 1103a. While ensuring that the temperature sensing element 130 can sense the temperature of the ejector tube 110, it also simplifies the connection between the temperature sensing element 130 and the ejector tube 110. When it is necessary to repair or replace the temperature sensing element 130, it can be easily disassembled and installed, effectively improving the convenience of operation for operators.

[0071] The shape of the heat-conducting part 1301 can be adapted to the outer contour of the tube body 1103a. Specifically, the shape of the heat-conducting part 1301 can be an arc-shaped plate, which not only allows for sufficient contact area between the heat-conducting part 1301 and the tube body 1103a, but also ensures that the two are in close contact. The heat-conducting surface 1301a can be formed on the side of the heat-conducting part 1301 that is in contact with the outer surface of the tube body 1103a.

[0072] The heat-conducting surface 1301a of the heat-conducting part 1301 can be in contact with the outer surface of the tube body 1103a by means of adhesive connection or snap-fit ​​connection. This application does not specifically limit the contact method between the heat-conducting surface 1301a of the heat-conducting part 1301 and the outer surface of the tube body 1103a.

[0073] In some embodiments, in conjunction with reference Figure 5 , Figure 6 , Figure 7 and Figure 4 The bracket 120 has a plate 1201, through which the ejector tube 110 passes. The heat-conducting part 1301 includes a first part 1301b and a second part 1301c connected together. The first part 1301b is parallel to the plate 1201, and the second part 1301c is perpendicular to the plate 1201. The heat-conducting surface 1301a is located on the second part 1301c. In this way, the first part 1301b and the second part 1301c can be arranged perpendicularly to each other. This ensures that the heat-conducting surface 1301a is in close contact with the ejector tube 110, while also preventing the components in the temperature sensing element 130 from being too close to the ejector tube 110. This reduces the influence of the temperature of the components in the temperature sensing element 130 on the temperature of the ejector tube 110, effectively improving the accuracy and service life of the temperature sensing element 130.

[0074] The first part 1301b and the second part 1301c can be detachably connected or integrally formed. The detachable connection can include plug-in connection or adhesive connection, etc., and this application does not make specific limitations in this regard.

[0075] The plate surface of the second part 1301c can be perpendicular to the plate surface of the first part 1301b, so that when the second part 1301c abuts against the side wall of the ejector pipe 110, the first part 1301b can form a spacing between the temperature sensing element 130 and the side wall of the ejector pipe 110, so as to avoid direct contact between the components in the temperature sensing element 130 and the ejector pipe 110, thereby avoiding interference or damage to the temperature sensing element 130.

[0076] In some embodiments, referring to Figure 5 、 Figure 6 、 Figure 7 and Figure 1 , the ejector pipe 110 is sleeved with a fire cover 150, the fire cover 150 has a bottom end surface 1501, and the second part 1301c has a top end surface 1301d, the top end surface 1301d and the bottom end surface 1501 have a distance H in a direction perpendicular to the plate body 1201, and the distance H is 6mm-12mm. The distance between the top end surface 1301d of the second part 1301c and the bottom end surface 1501 of the fire cover 150 can be in the above range, so as to avoid the distance between the temperature sensing element 130 and the heat source being too large or too small, thereby affecting the temperature sensing accuracy of the temperature sensing element 130, and greatly improving the reliability of the burner head 10.

[0077] Specifically, the fire cover 150 can form a plurality of combustion holes, and when the burner head 10 is in a combustion state, the fire cover 150 can uniformly disperse the flame generated by the burner head 10 into a plurality of small flames.

[0078] Specifically, the distance between the top end surface 1301d of the second part 1301c and the bottom end surface 1501 of the fire cover 150 should not be too large or too small. When the distance between the above two is too large, it can be understood that the spacing between the heat conducting part 1301 and the heat source is large, thereby affecting the accuracy of the temperature sensing element 130. When the distance between the above two is too small, the temperature sensing element 130 is easily disturbed by the heat source, thereby causing the temperature sensing element 130 to have inaccurate sensing results.

[0079] Specifically, the distance H is in a range of 6mm to 12mm, for example, 6mm, 8mm, 10mm, 12mm, etc. The distance H in this range can ensure that the temperature sensing element 130 senses the temperature of the ejector pipe 110, and can also avoid being affected by the temperature of the heat source. In an embodiment of the present application, the distance H is 8mm, which can well ensure the sensing effect of the temperature sensing element 130.

[0080] In some embodiments, referring to Figure 2 、 Figure 3 、 Figure 8The bracket 120 is provided with a connecting hole 121, and the fastener 140 is arranged in the connecting hole 121 and in contact with the hole wall of the connecting hole 121. The fastener 140 is provided with a receiving hole (not shown in the figure), and the temperature sensing piece 130 has a heat conduction part 1301 (for reference Figure 2 It should be understood that, in order to be arranged in the receiving hole, the heat conduction part 1301 needs to be matched with the receiving hole, for example, when the cross section of the receiving hole is circular, the heat conduction part 1301 can be a columnar body, and the cross section area of the columnar body cannot exceed the cross section area of the receiving hole. The heat conduction part 1301 is arranged in the receiving hole. In this way, the heat generated by the ejector pipe 110 can be transmitted to the fastener 140 through the bracket 120, and the temperature sensing piece 130 in contact with the fastener 140 can determine the temperature of the ejector pipe 110 by sensing the temperature of the fastener 140. Therefore, while ensuring that the temperature sensing piece 130 can sense the temperature of the ejector pipe 110, the connection structure of the furnace head 10 can also be effectively simplified, and the manufacturing difficulty and cost of the furnace head 10 can be reduced. In an embodiment not shown, the fastener 140 is a screw or bolt having a shaft, and the heat conduction part 1301 can be a sleeve, and the heat conduction part 1301 of the sleeve is sleeved on the shaft of the fastener 140. In an embodiment not shown, the fastener 140 is a screw or bolt having a head, and the heat conduction part 1301 can be a sheet, and the heat conduction part 1301 of the sheet is in contact with the head of the fastener 140.

[0081] Again referring to Figure 3 , Figure 8 , Figure 9 and Figure 12 , the fastener 140 can pass through the through hole 1301e and the connecting hole 121 in sequence to connect the temperature sensing piece 130 and the bracket 120, and the through hole 1301e can be formed on the heat conduction part 1301 of the temperature sensing piece 130. The diameter of the fastener 140 can be 3mm to 6mm (mm), for example, 3mm, 4mm, 5mm, 6mm. In this way, not only can the temperature sensing piece 130 and the bracket 120 be tightly connected, but also the situation that the bracket 120 has poor heat conduction due to the area of the connecting hole 121 being too large can be avoided. In an embodiment of the present application, the diameter of the fastener 140 is 4mm, which can ensure that the temperature sensing piece 130 and the bracket 120 are tightly connected.

[0082] Further, the end of the fastener 140 can be formed with an end cap, and the end cap can be provided with a receiving hole, and the heat conduction part 1301 can be placed in the receiving hole to sense the temperature of the fastener 140. In this way, the through hole 1301e does not need to be opened on the heat conduction part 1301, which can not only reduce the manufacturing difficulty of the temperature sensing piece 130, but also avoid the situation that the heat conduction part 1301 has poor heat conduction due to the area of the through hole 1301e being too large.

[0083] In some embodiments, referring to Figure 8 The temperature sensing element 130 is provided with a through hole 1301e, the bracket 120 is provided with a connecting hole 121, and the fastener 140 has a rod portion 1401 which is sequentially arranged in the through hole 1301e and the connecting hole 121 to connect the temperature sensing element 130 and the bracket 120, and the bracket 120 is provided with a heat insulation element 160. In this way, the heat insulation element 160 is arranged between the temperature sensing element 130 and the bracket 120, which can avoid the direct contact between the temperature sensing element 130 and the bracket 120, ensure that the temperature sensing element 130 is not disturbed and damaged by the heat of the bracket 120, and further improve the accuracy of temperature sensing and service life of the temperature sensing element 130.

[0084] Specifically, the heat insulation element 160 can be provided with a through hole, and the fastener 140 with the rod portion 1401 can sequentially pass through the through hole 1301e, the through hole and the connecting hole 121, so as to firmly connect the temperature sensing element 130, the heat insulation element 160 and the bracket 120 by the fastener 140. Of course, in an embodiment not shown, the heat insulation element 160 can not be provided with a through hole, and only needs to be clamped between the temperature sensing element 130 and the bracket 120 to avoid the direct distance between the above two, and the present application does not make specific limitation on whether the heat insulation element 160 is provided with a through hole.

[0085] Specifically, the heat insulation element 160 can be made of rock wool or fiber material, preferably rock wool, which has excellent high temperature resistance and stability, effectively ensuring the heat insulation effect of the heat insulation element 160.

[0086] In some embodiments, referring to Figure 9 and Figure 9 The temperature sensing element 130 further has a sensing portion 1302 and a signal transmission line 1303, both ends of the sensing portion 1302 are connected with the heat conduction portion 1301 and the signal transmission line 1303 respectively, the sensing portion 1302 obtains temperature information through the heat conduction portion 1301, and the signal transmission line 1303 is connected with the sensing portion 1302 to transmit the temperature information to the outside. In this way, the heat conduction portion 1301 can be in contact with the ejector pipe 110 or the fastener 140, so that the surface heat of the ejector pipe 110 or the fastener 140 can be transmitted to the sensing portion 1302, and the sensing portion 1302 can convert the heat into specific temperature information and transmit it to the outside through the signal transmission line 1303, thereby realizing the temperature sensing and monitoring of the ejector pipe 110 or the fastener 140. Through the direct contact between the temperature sensing element 130 and the ejector pipe 110 or the fastener 140, the interference of the external use environment on the temperature sensing element 130 can be avoided, and the accuracy of the temperature sensing result of the temperature sensing element 130 can be effectively ensured.

[0087] Specifically, the two ends of the sensing part 1302 can be connected with the heat conduction part 1301 and the signal transmission line 1303 respectively, the heat conduction part 1301 can be used to transfer the sensed heat to the sensing part 1302, the sensing part 1302 can convert the perceived heat into temperature information, and the signal transmission line 1303 can transmit the temperature information to an external device. Through the above split design, the structure and layout of the temperature sensing piece 130 can be more stable, and the risk of failure caused by complex structure can be reduced.

[0088] The signal transmission line 1303 can transmit the temperature information obtained by the sensing part 1302 to an external control system. During transmission, the signal transmission line 1303 can effectively reduce the influence of electromagnetic interference, dust, humidity and other factors on the signal, thereby improving the reliability of the temperature sensing piece 130 and the accuracy of the temperature sensing result.

[0089] In some embodiments, referring to Figure 10 , the sensing part 1302 includes a shell 1302a and a sensing chip 1302b, the sensing chip 1302b is arranged in the shell 1302a, and one end of the signal transmission line 1303 is connected with the sensing chip 1302b. In this way, the sensing chip 1302b can be arranged in the shell 1302a to effectively protect the sensing chip 1302b from the influence of external environment such as dust, water vapor or mechanical impact, thereby greatly improving the service life and reliability of the sensing chip 1302b. Moreover, the direct connection between the sensing chip 1302b and the signal transmission line 1303 greatly reduces the delay of signal transmission, so that the temperature sensing chip can quickly respond to temperature changes and transmit temperature information outward.

[0090] Specifically, the sensing chip 1302b can quickly respond to temperature changes and convert them into electrical signals. Moreover, through the efficient heat transfer of the heat conduction part 1301, the sensing chip 1302b can more accurately capture the slight changes in temperature.

[0091] Specifically, the sensing chip 1302b can be arranged in the shell 1302a to avoid interference or influence of external environment such as high temperature or water vapor on the sensing chip 1302b. The shell 1302a and the sensing chip 1302b can be filled with a heat-conducting material, such as heat-conducting resin. In this way, the air between the sensing chip 1302b and the shell 1302a can be excluded, the contact thermal resistance is reduced, and the efficiency of heat transfer to the sensing chip 1302b is improved.

[0092] Further, the shape of the sensing chip 1302b can be spherical or square, etc. to increase the contact area between the sensing chip 1302b and the heat-conducting material, thereby further improving the efficiency of heat transfer to the sensing chip 1302b. The shape of the sensing chip 1302b is not limited in the present application.

[0093] According to another aspect of the present application, in combination with reference to Figure 11 and Figure 13 A burner 20 is also provided, comprising a burner base 210, a burner cap 150 and the burner head 10 as described above, the burner cap 150 and the burner base 210 form a gas mixing cavity, and the gas mixing cavity is in communication with the ejector pipe 110. Since the burner head 10 as described above has the beneficial effects as described above, the burner 20 comprising the burner head 10 as described above also has the beneficial effects as described above, which will not be repeated here.

[0094] Specifically, the burner base 210 can uniformly distribute the gas delivered by the ejector pipe 110 to each combustion area, and the burner cap 150 arranged on the burner base 210 can uniformly disperse the flame generated by the burner 20 into multiple small flames when the burner 20 is burning, thereby increasing the combustion area of the burner 20 and improving the heating efficiency of the burner 20.

[0095] According to still another aspect of the present application, in combination with reference to ​ A cooktop 30 is also provided, comprising a bottom shell 310, a panel 320 and the burner 20 as described above, the bottom shell 310 forms an installation cavity with an opening, the panel 320 covers the opening, the panel 320 is provided with a through hole, the burner 20 is arranged in the through hole, and part of the burner 20 is located in the installation cavity and part of the burner 20 is located outside the installation cavity.
