Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of beverage making, in particular to a probe mounting assembly, a boiler and a beverage machine. BACKGROUND

[0002] With the increasing demand for beverages such as coffee and milk tea, the application occasions of beverage machines are also more and more extensive. In the process of making beverages by the beverage machine, steam is often needed. For example, when making milk coffee, steam is needed to make hot milk or hot milk foam. Therefore, the beverage machine generally includes a boiler that can generate steam.

[0003] In order to detect the water level in the boiler and prevent the boiler from dry burning, a probe body is generally installed on the boiler body. The outer peripheral surface of the probe body is generally partially wrapped with an insulating material, and only a small section is exposed as a detection end. The detection end of the probe body has an optimal horizontal height in the boiler body, so as to achieve the optimal detection effect. However, the probe body in the related art is prone to relative displacement with respect to the wrapping layer of the insulating material, which causes the total length of the detection end for measurement to change, which is equivalent to the change of the horizontal height of the detection end, and the detection result of the probe body is inaccurate. UTILITY MODEL CONTENT

[0004] Therefore, the present application provides a probe mounting assembly, a boiler and a beverage machine, which aims to solve the problem that the probe body in the related art is prone to relative displacement with respect to the wrapping layer of the insulating material, which causes the total length of the detection end for measurement to change, which is equivalent to the change of the horizontal height of the detection end, and the detection result of the probe body is inaccurate.

[0005] In a first aspect, the present application provides a probe mounting assembly, which comprises a connecting seat, a probe structure and a fixing member. The connecting seat has a socket. The probe structure is arranged in the socket, and the probe structure comprises a probe body and an insulating heat shrink tube. The probe body comprises a first section in the socket, and the outer peripheral surface of the first section has a first anti-falling groove. The insulating heat shrink tube is sleeved on the outer peripheral surface of the probe body and is in contact with the groove wall of the first anti-falling groove. The detection end of the probe body is exposed to the insulating heat shrink tube. The fixing member is arranged between the inner wall surface of the socket and the probe structure. The fixing member is provided with an elastic compression rib, and the elastic compression rib is in contact with the part of the insulating heat shrink tube corresponding to the first anti-falling groove.

[0006] According to the probe mounting assembly, the insulating heat-shrinkable tube is sleeved on the outer circumferential surface of the probe body. In this way, when the probe mounting assembly is used in a boiler, the working environment of the probe mounting assembly is usually a high-temperature environment. Therefore, the high temperature generated by the boiler can cause the insulating heat-shrinkable tube to shrink to a certain extent, so that the insulating heat-shrinkable tube tightly holds the probe body, the insulating heat-shrinkable tube is in contact with the probe body everywhere, and the cooperation reliability between the probe body and the insulating heat-shrinkable tube is improved, thereby limiting the relative movement between the probe body and the insulating heat-shrinkable tube, maintaining the relative position between the detection end and the insulating heat-shrinkable tube, maintaining the length of the detection end exposed, maintaining the detection end at a predetermined optimal horizontal height in the boiler, improving the detection accuracy of the probe structure, and further avoiding air leakage between the probe body and the insulating heat-shrinkable tube of the boiler.

[0007] The first anti-falling groove is arranged on the outer circumferential surface of the part of the probe body in the insertion hole. The insulating heat-shrinkable tube is in contact with the groove wall of the first anti-falling groove. In this way, on the one hand, the first anti-falling groove can increase the contact area between the insulating heat-shrinkable tube and the probe body; on the other hand, the two side groove walls of the first anti-falling groove in the axial direction of the probe body can limit the mutual movement between the probe body and the insulating heat-shrinkable tube. The above two aspects can further improve the cooperation reliability between the probe body and the insulating heat-shrinkable tube, avoid the relative movement between the probe body and the insulating heat-shrinkable tube to a certain extent, improve the detection accuracy of the probe structure, and further avoid air leakage between the probe body and the insulating heat-shrinkable tube of the boiler.

[0008] The fixing member is provided with an elastic pressing rib. The elastic pressing rib is abutted against the part of the insulating heat-shrinkable tube corresponding to the first anti-falling groove. Since the insulating heat-shrinkable tube is in contact with the groove wall of the first anti-falling groove, the part of the insulating heat-shrinkable tube corresponding to the first anti-falling groove can have a certain recessed area. When the elastic pressing rib is abutted against the part of the insulating heat-shrinkable tube corresponding to the first anti-falling groove, the elastic pressing rib can be limited in the recessed area. The two side wall surfaces of the recessed area in the axial direction of the probe body and the elastic pressing rib form a limit, thereby improving the fixing effect of the fixing member on the probe structure and preventing the movement of the probe structure relative to the connecting seat.

[0014] In a possible implementation manner of the first aspect of the present application, a part of the elastic clamp clamps the elastic compression rib.

[0015] In a possible implementation manner of the first aspect of the present application, the probe mounting assembly comprises a sealing ring, the sealing ring is located between the fixing member and the stepped portion, and is in interference fit between the probe structure and the inner circumferential surface of the connecting seat.

[0018] In a possible implementation manner of the first aspect of the present application, the insulating heat-shrinkable tube comprises a plurality of heat-shrinkable layers, the plurality of heat-shrinkable layers are sequentially distributed in the radial direction of the probe body, and each heat-shrinkable layer surrounds the probe body.

[0019] In a possible implementation manner of the first aspect of the present application, the material of the insulating heat-shrinkable tube is Teflon.

[0020] In a second aspect, the present application provides a boiler, comprising: a furnace body and a probe mounting assembly.

[0021] According to the boiler of the present application, the insulating heat shrink tube is sleeved on the outer circumferential surface of the probe body. In this way, the high temperature generated by the boiler can cause the insulating heat shrink tube to shrink to a certain extent, so that the insulating heat shrink tube tightly holds the probe body, the insulating heat shrink tube is in contact with the probe body everywhere, the cooperation reliability between the probe body and the insulating heat shrink tube can be improved, so as to limit the relative movement between the probe body and the insulating heat tube, facilitate maintaining the relative position between the detection end and the insulating heat shrink tube unchanged, that is, maintaining the exposed length of the detection end unchanged, and facilitate maintaining the detection end at a predetermined optimal horizontal height in the furnace body at all times, to a certain extent, avoiding the influence of the relative movement between the probe body and the insulating heat shrink tube on the exposed size of the detection end, and further avoiding the change of the horizontal height of the detection end in the furnace body caused by the change of the exposed size of the detection end, thereby facilitating improving the detection accuracy of the probe structure, and further avoiding the gas leakage between the probe body and the insulating heat shrink tube of the boiler.

[0037] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0038] In the process of making a beverage by using a beverage machine, steam is often needed to be used. For example, taking a coffee machine as an example, when making milk coffee by using the beverage machine, the water in the beverage machine needs to be heated to generate steam by using the boiler in the beverage machine, and the steam is used to make hot milk or hot milk foam.

[0039] In order to improve the reliability of the boiler, the water level in the boiler often needs to be monitored. Based on this, please refer to Figure 1 The boiler 100 comprises a furnace body 20 and a probe structure 2. Specifically, the furnace body 20 has a mounting hole 201. An abutting frame 2011 is arranged on the inner circumferential wall of the mounting hole 201. The lower end of the abutting frame 2011 is provided with a necked portion 20111. The inner circumferential surface of the abutting frame 2011, which is above the necked portion 20111, is formed with an internal thread.

[0040] The probe structure 2 comprises a probe body 21, an inner sleeve 23, an outer sleeve 24 and a threaded sleeve 25. The material of the probe body 21 is metal. The material of the inner sleeve 23 and the outer sleeve 24 can be heat-expandable and cold-shrinkable Teflon. The material of the threaded sleeve 25 is metal. The inner sleeve 23 is sleeved on the outer periphery of the probe body 21. The outer sleeve 24 is sleeved on the outer periphery of the inner sleeve 23. The threaded sleeve 25 is sleeved on the upper end of the outer sleeve 24.

[0041] The probe structure 2 is arranged in the abutting frame 2011. The external thread on the outer circumferential surface of the threaded sleeve 25 is threadedly connected with the internal thread of the abutting frame 2011. The necked portion 20111 abuts against the portion of the outer sleeve 24 below the threaded sleeve 25, and the portion of the outer sleeve 24 is pressed and deformed. The deformation of the outer sleeve 24 causes the inner sleeve 23 to also deform in the direction of the probe body 21 and abut against the outer circumferential surface of the probe body 21 to achieve sealing.

[0042] However, the above-mentioned boiler 100 at least has the following defects:

[0043] 1. The abutment relationship between the probe body 21 and the inner sleeve 23 only occurs at the position corresponding to the necked portion 20111, that is, the probe body 21 and the inner sleeve 23 are not fixed and sealed together everywhere. In addition, the boiler 100 is often in a high-temperature environment during use, and the inner sleeve 23 will expand and deform due to thermal expansion, which will reduce the connection reliability between the inner sleeve 23 and the probe body 21. In addition, it is easy to cause the probe body 21 to move relative to the inner sleeve 23 due to the change of the internal pressure of the boiler 100 and the vibration of the boiler 100 itself. In this way, on the one hand, the exposed length of the probe body 21 changes. For the probe body 21, the probe body 21 has an optimal exposed length, that is, the probe body 21 has an optimal horizontal height in the boiler 100, so as to achieve the optimal detection effect. If it is too short, it is not easy to detect the signal, and if it is too long, it is easy to mis-detect the water vapor in the surrounding environment as a liquid level signal, both of which will cause the detection result of the probe body 21 to be inaccurate. And when disassembling the probe structure 2, the probe body 21 is also easy to come off the inner sleeve 23. On the other hand, the poor sealing between the inner sleeve 23 and the probe body 21 is easy to cause the boiler 100 to leak.

[0044] 2. In order to achieve the sealing purpose between the probe body 21 and the inner sleeve 23, during installation, the outer sleeve 24 will be deformed by rotating extrusion and form an external thread matched with the internal thread of the abutment frame 2011. Due to the existence of the external thread on the above-mentioned outer sleeve 24, when disassembling the probe structure 2, it is impossible to normally pull out the threaded sleeve 25 by rotating it alone, and the threaded sleeve 25 and the outer sleeve 24 need to be rotated at the same time to disassemble. In addition, the abutment frame 2011 cooperating with the probe structure 2 needs to be additionally provided on the furnace body 20. Therefore, the assembly relationship between the above-mentioned probe structure 2 and the furnace body 20 not only causes the disassembly of the probe structure 2 to be relatively complex, but also the overall structure is complex and the cost is high.

[0045] Therefore, in order to solve at least one of the above technical problems, the present application provides a probe mounting assembly.

[0046] Please refer to Figure 2 , Figure 3 and Figure 4 , the probe mounting assembly 10 according to the embodiment of the present application can include a connecting seat 1, a probe structure 2 and a fixing piece 3.

[0047] The material of the connecting seat 1 includes but is not limited to metal or plastic. For example, the material of the connecting seat 1 is copper, or aluminum, etc.

[0048] The connecting seat 1 has a socket 11. For example, the connecting seat 1 can be in a cylindrical shape to define the socket 11.

[0049] The probe structure 2 is entirely inserted into the socket 11. In this way, the probe structure 2 can penetrate the connecting seat 1.

[0050] Please continue to refer to Figure 3 and Figure 4 , the probe structure 2 includes a probe body 21 and an insulating heat shrink tube 22.

[0051] The probe body 21 is in a needle shape. The probe body 21 is used to detect the water temperature. The material of the probe body 21 includes but is not limited to metal.

[0052] The insulating heat shrink tube 22 plays an insulating protection role. The material of the insulating heat shrink tube 22 is a heat shrinkage and expansion material. For example, the material of the insulating heat shrink tube 22 is Teflon, thereby the cost is low.

[0053] The insulating heat shrink tube 22 is sleeved on the outer circumferential surface of the probe body 21. The detection end 213 of the probe body 21 is exposed to the insulating heat shrink tube 22. In this way, when the probe mounting assembly 10 is used in the boiler 100, the working environment of the probe mounting assembly 10 is often a high-temperature environment, and therefore the high temperature generated by the boiler 100 can cause the insulating heat shrink tube 22 to shrink to a certain extent, so that the insulating heat shrink tube 22 tightly holds the probe body 21, the insulating heat shrink tube 22 can be in contact with the probe body 21 everywhere, the cooperation reliability between the probe body 21 and the insulating heat shrink tube 22 can be improved, thereby limiting the relative movement between the probe body 21 and the insulating heat shrink tube 22, which is beneficial to maintaining the relative position between the detection end 213 and the insulating heat shrink tube 22 unchanged, that is, beneficial to maintaining the exposed length of the detection end 213 unchanged, which is beneficial to maintaining the detection end 213 at a predetermined optimal horizontal height in the boiler 100 at all times, which is beneficial to improving the detection accuracy of the probe structure 2, and at the same time, the air leakage between the probe body 21 and the insulating heat shrink tube 22 caused by the boiler 100 can be avoided.

[0054] Please refer to Figure 3 , Figure 4 and Figure 5 , the probe body 21 includes a first section 214. The first section 214 is located in the socket 11. The outer circumferential surface of the first section 214 has a first anti-falling groove 211.

[0055] In the specific example shown in Figure 5 , the first anti-falling groove 211 is one. In other embodiments, the first anti-falling groove 211 can also be multiple, and the multiple first anti-falling grooves 211 are arranged along the axial direction of the probe body 21.

[0056] The insulating heat-shrinkable tube 22 is attached to the groove wall of the first anti-drop groove 211. In this way, on the one hand, the first anti-drop groove 211 can increase the contact area between the insulating heat-shrinkable tube 22 and the probe body 21; on the other hand, the two side groove walls of the first anti-drop groove 211 along the axial direction of the probe body 21 can limit the mutual movement between the probe body 21 and the insulating heat-shrinkable tube 22. The above two aspects can further improve the cooperation reliability between the probe body 21 and the insulating heat-shrinkable tube 22, to a certain extent, avoid the relative movement between the probe body 21 and the insulating heat-shrinkable tube 22, which is conducive to improving the detection accuracy of the probe structure 2, and can also avoid the gas leakage between the probe body 21 and the insulating heat-shrinkable tube 22.

[0057] The material of the fixing member 3 includes but is not limited to metal. For example, the material of the fixing member 3 is copper.

[0058] The fixing member 3 is arranged between the inner wall surface of the insertion hole 11 and the probe structure 2. The arrangement of the fixing member 3 can facilitate the positioning of the probe structure 2, preventing the entire probe structure 2 from moving along the axial direction of the probe body 21 relative to the connecting seat 1.

[0059] Please refer to Figure 5 and Figure 6 , the fixing member 3 is provided with an elastic compression rib 31. Exemplarily, the elastic compression rib 31 and the fixing member 3 are an integral molded part. In this way, it is conducive to improving the connection strength between the elastic compression rib 31 and the fixing member 3, simplifying the processing technology between the elastic compression rib 31 and the fixing member 3, and reducing the manufacturing cost between the elastic compression rib 31 and the fixing member 3. In other embodiments, the two can be connected by clamping or welding.

[0060] The elastic compression rib 31 abuts against the part of the insulating heat-shrinkable tube 22 corresponding to the first anti-drop groove 211. Specifically, since the insulating heat-shrinkable tube 22 is attached to the groove wall of the first anti-drop groove 211, the position of the insulating heat-shrinkable tube 22 corresponding to the first anti-drop groove 211 can form a recessed area. When the elastic compression rib 31 abuts against the part of the insulating heat-shrinkable tube 22 corresponding to the first anti-drop groove 211, it can be limited in the recessed area. The two side walls of the recessed area along the axial direction of the probe body 21 form a limit between the elastic compression rib 31, thereby improving the fixing effect of the fixing member 3 on the probe structure 2, preventing the movement of the probe structure 2 relative to the connecting seat 1.

[0061] In some embodiments of the present application, the first anti-extraction groove 211 extends annularly along the entire circumference of the probe body 21. In this way, on the one hand, the contact area between the insulating heat-shrink tube 22 and the probe body 21 can be further increased; on the other hand, the two side groove walls of the first anti-extraction groove 211 in the axial direction of the probe body 21 can more effectively limit the mutual movement between the probe body 21 and the insulating heat-shrink tube 22. The above two aspects can further improve the cooperation reliability between the probe body 21 and the insulating heat-shrink tube 22, further avoid the relative movement between the probe body 21 and the insulating heat-shrink tube 22, and help to improve the detection accuracy of the probe structure 2, and also can avoid the gas leakage between the probe body 21 and the insulating heat-shrink tube 22.

[0062] Further, please refer to Figure 6 , the elastic compression rib 31 extends annularly along the entire circumference of the probe body 21. In this way, the fixing effect of the fixing member 3 on the probe structure 2 can be further improved, and the movement of the probe structure 2 relative to the connecting seat 1 can be prevented.

[0063] Of course, the present application is not limited thereto, and in other embodiments, the first anti-extraction groove 211 and the elastic compression rib 31 can also not extend annularly. For example, the first anti-extraction groove 211 includes a plurality of sub-grooves. The plurality of sub-grooves are distributed at intervals in the circumferential direction of the probe body 21. The elastic compression rib 31 includes a plurality of sub-compression ribs. The plurality of sub-compression ribs correspond one-to-one to the plurality of sub-grooves.

[0064] In some embodiments of the present application, please refer to Figure 5 and Figure 6 , at least one end face of the fixing member 3 in the axial direction of the probe body 21 is recessed to define a groove 32 extending along the entire circumference of the probe body 21. The groove 32 extends to the outer circumferential surface of the fixing member 3. The elastic compression rib 31 is fixed to the end of the groove bottom wall of the groove 32. The end is the end of the groove bottom wall of the groove 32 close to the outer circumferential surface of the fixing member 3. In this way, the structure is simple, and the connection of the elastic compression rib 31 and the groove bottom wall of the groove 32 can make the overall structure of the fixing member 3 and the elastic compression rib 31 relatively compact.

[0065] For example, in the specific examples shown in Figure 5 and Figure 6 , one end face of the fixing member 3 in the axial direction of the probe body 21 is recessed to define a groove 32 extending along the entire circumference of the probe body 21, at this time the elastic compression rib 31 is one, and the first anti-extraction groove 211 is also one.

[0066] Further, the two end faces of the fixing member 3 in the axial direction of the probe body 21 are recessed to define two grooves 32 extending along the entire circumference of the probe body 21. The two grooves 32 correspond to the two elastic compression ribs 31. The corresponding first anti-disengagement grooves 211 can also be two, and the two elastic compression ribs 31 correspond to the two first anti-disengagement grooves 211 one by one.

[0067] Of course, the present application is not limited thereto, and in other embodiments, the fixing member 3 can also not be provided with the above-mentioned grooves 32.

[0068] In some embodiments of the present application, please continue to refer to Figure 5 , the thickness of the elastic compression rib 31 gradually decreases in the axial direction of the probe body 21 and in the direction away from the fixing member 3. In this way, it is beneficial to improve the elastic deformation ability of the elastic compression rib 31, thereby improving the compression effect of the elastic compression rib 31 on the probe structure 2.

[0069] In some embodiments of the present application, the fixing member 3 is detachably arranged in the insertion hole 11. In this way, the disassembly and assembly of the probe structure 2 and the connecting seat 1 can be facilitated, thereby facilitating the maintenance and replacement of the probe structure 2.

[0070] Further, please refer to Figure 4 , one end of the insertion hole 11 forms a disassembly opening 111 for disassembling and assembling the fixing member 3. In this way, the fixing member 3 can be installed in the insertion hole 11 from the disassembly opening 111, or taken out from the disassembly opening 111.

[0071] On this basis, in order to prevent the fixing member 3 from coming out of the disassembly opening 111 of the insertion hole 11 due to non-human factors after assembly, the connecting seat 1 is formed with a stepped portion 112 at the end opposite to the disassembly opening 111. The probe mounting assembly 10 comprises an elastic clamp 4. The peripheral wall of the connecting seat 1 has an avoiding hole 12. The elastic clamp 4 is limited in the avoiding hole 12. A part of the elastic clamp 4 extends into the insertion hole 11 through the avoiding hole 12. In this way, the fixing member 3 can be limited between the stepped portion 112 and the elastic clamp 4.

[0072] Specifically, when assembling the probe mounting assembly 10, the probe structure 2 can be first arranged in the insertion hole 11, then the fixing member 3 is placed in the insertion hole 11 through the disassembly opening 111, then the elastic clamp 4 is limited in the avoiding hole 12 from the outer circumferential side of the connecting seat 1, and a part of the elastic clamp 4 is located in the insertion hole 11, and the fixing member 3 is limited in the insertion hole 11 by the cooperation of the elastic clamp 4 and the stepped portion 112. When disassembling the probe mounting assembly 10, the elastic clamp 4 is first removed, and then the fixing member 3 and the probe structure 2 are taken out from the disassembly opening 111.

[0073] As can be seen from the above description, the entire probe mounting assembly 10 is simple in structure and convenient to disassemble and assemble.

[0074] Further, a portion of the elastic clip 4 clamps the elastic compression rib 31. In this way, the matching reliability between the elastic compression rib 31 and the probe structure 2 can be higher, and further, the relative movement of the probe structure 2 relative to the fixing member 3 can be prevented.

[0075] Of course, it can be understood that in other embodiments, the elastic compression rib 31 can also only clamp the probe structure 2.

[0076] In some embodiments of the present application, referring to Figure 4 , the probe mounting assembly 10 further comprises a sealing ring 5. The sealing ring 5 is located in the insertion hole 11 and between the fixing member 3 and the stepped portion 112. The sealing ring 5 is in interference fit between the inner circumferential surface of the probe structure 2 and the connecting seat 1. In this way, on the one hand, by arranging the sealing ring 5 between the fixing member 3 and the stepped portion 112, the fixing member 3 can be used to limit the sealing ring 5, preventing the sealing ring 5 from coming out of the dismounting opening 111; on the other hand, the interference fit of the sealing ring 5 between the inner circumferential surface of the probe structure 2 and the connecting seat 1 is beneficial to improve the sealing between the probe structure 2 and the connecting seat 1, preventing the problem of air leakage between the probe structure 2 and the connecting seat 1. In addition, the sealing ring 5 is simple in structure and convenient to disassemble and assemble.

[0077] In some embodiments of the present application, referring to Figure 3 and Figure 7 , the probe body 21 comprises a second section 215. The second section 215 can be connected with the first section 214, or the second section 215 can be integrally manufactured with the first section 214. The second section 215 is between the detection end 213 and the connecting seat 1. The outer circumferential surface of the second section 215 is provided with a second anti-falling groove 212. The insulating heat-shrinkable tube 22 is attached to the groove wall of the second anti-falling groove 212. In this way, on the one hand, the arrangement of the second anti-falling groove 212 can increase the contact area between the insulating heat-shrinkable tube 22 and the probe body 21; on the other hand, the two side groove walls of the second anti-falling groove 212 in the axial direction of the probe body 21 can limit the mutual movement between the probe body 21 and the insulating heat-shrinkable tube 22. The above two aspects can further improve the matching reliability between the probe body 21 and the insulating heat-shrinkable tube 22, to a certain extent, avoid the relative movement between the probe body 21 and the insulating heat-shrinkable tube 22, which is beneficial to improve the detection accuracy of the probe structure 2, and also can avoid the air leakage between the probe body 21 and the insulating heat-shrinkable tube 22 of the boiler 100.

[0078] In some embodiments of the present application, the second anti-escape groove 212 extends annularly along the entire circumference of the probe body 21. In this way, on the one hand, the contact area between the insulating heat-shrinkable tube 22 and the probe body 21 can be further increased; on the other hand, the two side groove walls of the second anti-escape groove 212 in the axial direction of the probe body 21 can more effectively limit the mutual movement between the probe body 21 and the insulating heat-shrinkable tube 22. The above two aspects can further improve the cooperation reliability between the probe body 21 and the insulating heat-shrinkable tube 22, to a certain extent, avoid the relative movement between the probe body 21 and the insulating heat-shrinkable tube 22, improve the detection accuracy of the probe structure 2, and also avoid the gas leakage between the probe body 21 and the insulating heat-shrinkable tube 22.

[0079] Of course, the present application is not limited thereto, and in other embodiments, the second anti-escape groove 212 can also not extend annularly. For example, the second anti-escape groove 212 includes a plurality of sub-anti-escape grooves. The plurality of sub-anti-escape grooves are arranged at intervals along the circumference of the probe body 21.

[0080] For example, the second anti-escape groove 212 can be a plurality of second anti-escape grooves 212 arranged at intervals in the axial direction of the probe body 21. For another example, the second anti-escape groove 212 is one.

[0081] In some embodiments of the present application, please continue to refer to Figure 7 , and in combination with Figure 4 and Figure 5 , the insulating heat-shrinkable tube 22 includes a plurality of heat-shrinkable layers 221. Wherein, “a plurality of layers” refers to two or more layers.

[0082] The plurality of heat-shrinkable layers 221 are arranged in sequence in the radial direction of the probe body 21. Each heat-shrinkable layer 221 surrounds the probe body 21. In this way, the arrangement of the plurality of heat-shrinkable layers 221 is conducive to increasing the thickness of the insulating heat-shrinkable tube 22, preventing the insulating heat-shrinkable tube 22 from being pierced by the elastic compression rib 31 when cooperating with the elastic compression rib 31, and further improving the sealing performance between the insulating heat-shrinkable tube 22 and the probe body 21.

[0083] In some embodiments of the present application, please refer to Figure 2 and Figure 3 , the probe structure 2 further includes a wiring terminal 26. The wiring terminal 26 is arranged at one end of the probe body 21 opposite the detection end 213. In this way, the signal detected by the probe body 21 can be conveniently led out by using the wiring terminal 26.

[0084] Please refer to Figure 8 and Figure 9 , the present application also provides a boiler 100. The boiler 100 according to the embodiments of the present application can include a furnace body 20 and the probe mounting assembly 10 in any of the above technical solutions.

[0085] The furnace body 20 has a mounting hole 201. The probe mounting assembly 10 is mounted at the mounting hole 201 by means of the connecting seat 1, and the probe end 213 is located in the furnace body 20.

[0086] For example, the connecting seat 1 can be interference-fitted in the mounting hole 201. In this way, the structure is simple, the disassembly and assembly are convenient, and the cost is reduced.

[0087] For another example, the connecting seat 1 can be inserted into the mounting hole 201 and bonded or welded between the connecting seat 1 and the furnace body 20.

[0088] On this basis, in order to further improve the sealing between the connecting seat 1 and the mounting hole 201, a flexible sealing ring is arranged between the outer circumferential surface of the connecting seat 1 and the inner circumferential surface of the mounting hole 201.

[0089] In addition, the application also provides a beverage machine. The beverage machine comprises a beverage machine body and the boiler 100 in any of the technical solutions described above.
