Description

Technical Field

[0001] This utility model relates to the field of liquid heating products, and in particular to an underwater probe assembly. Background Technology

[0002] Electric kettles, health pots, coffee machines and other liquid heating products need to be equipped with temperature probes to measure the temperature of the water inside the kettle in order to achieve automatic control, such as turning off the heating device after detecting that the water has boiled, or turning on the heating device when the water is below the preset temperature and turning off the heating device when the water reaches the preset temperature to achieve a constant temperature effect.

[0003] Temperature probes come in two installation methods: internal and external. External installations indirectly detect the water temperature inside the kettle by conducting heat through the kettle's inner liner. This method is easy to install and has a lower cost, but the accuracy and timeliness of the measurement are poor. Internal installations, on the other hand, insert the temperature probe into the kettle's inner liner to directly detect the water temperature. This method has high accuracy and can detect changes in water temperature in a timely manner. However, because it requires waterproofing and leak prevention, the installation structure is relatively complex. This type of temperature probe is often referred to as an underwater probe in the industry.

[0004] Existing underwater probes typically have a ring plate protruding in the middle of the probe and a threaded tail. During installation, the tail of the probe and the signal cable need to be passed through the through hole on the inner liner of the water tank from the inside. Then, a nut is screwed onto the tail of the probe on the outside of the inner liner, and the nut and the ring plate are used to clamp the inner liner wall for fixation. A sealing ring is set at the rear of the ring plate and pressed against the inner wall of the inner liner to achieve a seal. The installation is relatively cumbersome and not conducive to automated assembly. When turning the nut, the probe may rotate as a whole, which may cause the sealing ring and the probe to be misaligned or damaged, thus affecting the sealing effect. Utility Model Content

[0005] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide an underwater probe assembly that is easy to assemble and helps to ensure a sealing effect.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0007] A water probe assembly for installation on the inner tank of a liquid heating product, the inner tank having through holes and screw holes spaced apart by a distance, comprising:

[0008] A pressure plate, with a temperature probe fixed at the front and a mounting hole at the rear; the temperature probe is inserted into the through hole and extends into the inner liner, and when the temperature probe is inserted into the through hole, the mounting hole is aligned with the screw hole.

[0009] A sealing element is provided with a connection hole that is interference-fitted with the temperature probe. The sealing element is sleeved on the outside of the temperature probe through the connection hole and can be clamped by the outer wall of the inner liner and the pressure plate.

[0010] Preferably, the seal is elastic.

[0011] Preferably, the sealing element is a silicone element.

[0012] Preferably, one end of the sealing element has a sealing ring that protrudes around the temperature probe, and the sealing ring is used to abut against the outer wall of the inner liner.

[0013] Preferably, the front part of the pressure plate is provided with a first folding plate for abutting against the outer wall of the inner liner, and the rear part is provided with a second folding plate for abutting against the outer wall of the inner liner.

[0014] Preferably, there are multiple first folding plates spaced apart from each other, and multiple second folding plates spaced apart from each other.

[0015] Preferably, the outer wall of the inner liner has a first portion for abutting against the first folding plate and a second portion for abutting against the second folding plate, and there is a height difference between the first portion and the second portion. The height difference between the tail of the first folding plate and the tail of the second folding plate is adapted to the height difference between the first portion and the second portion.

[0016] Preferably, the mounting hole is an oblong hole.

[0017] Preferably, the pressure plate is stepped, with its front portion closer to the outer wall of the inner liner than its rear portion.

[0018] Preferably, the temperature probe is adapted to the through hole; the temperature probe is riveted and fixed to the pressure plate.

[0019] The beneficial effects of this utility model are as follows: This underwater probe assembly can be adapted to the through holes and screw holes on the inner tank. During installation, simply insert the temperature probe into the through hole, then use a screw to pass through the mounting hole and screw it into the screw hole of the inner tank. After installation, the sealing element can be clamped by the outer wall of the inner tank and the pressure plate. Combined with the interference fit connection hole on the sealing element with the temperature probe, it can achieve a good sealing effect. Furthermore, during the installation process, the temperature probe will not be rotated by external force, which can effectively prevent the sealing element from being misaligned or damaged, and can also ensure the accuracy of the sealing element's installation position. Thus, it can effectively ensure the sealing effect and facilitate assembly operations. Attached Figure Description

[0027] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0028] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0029] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0030] Reference Figures 1 to 4In a preferred embodiment of this utility model, an underwater probe assembly is used to be installed on the inner liner 10 of a liquid heating product. The inner liner 10 is provided with through holes 11 and screw holes 13 spaced apart from each other. The assembly includes: a pressure plate 21, with a temperature probe 22 fixed at the front and a mounting hole 23 at the rear; the temperature probe 22 is used to insert into the through hole 11 and extend into the inner liner 10, and when the temperature probe 22 is inserted into the through hole 11, the mounting hole 23 is aligned with the screw hole 13; and a sealing member 30, which is provided with a connecting hole 31 that is interference-fitted with the temperature probe 22. The sealing member 30 is sleeved on the outside of the temperature probe 22 through the connecting hole 31 and can be clamped by the outer wall of the inner liner 10 and the pressure plate 21. This underwater probe assembly is compatible with the through hole 11 and screw hole 13 on the inner tank 10. During installation, simply insert the temperature probe 22 into the through hole 11, and then use a screw to pass through the mounting hole 23 and screw it into the screw hole 13 of the inner tank 10. After installation, the sealing element 30 can be clamped by the outer wall of the inner tank 10 and the pressure plate 21. Combined with the interference fit connection hole 31 on the sealing element 30 and the temperature probe 22, it can achieve a good sealing effect. During the installation process, the temperature probe 22 will not be rotated by external force, which can effectively prevent the sealing element 30 from being misaligned or damaged, and can also ensure the accurate installation position of the sealing element 30. This can effectively ensure the sealing effect and facilitate assembly.

[0031] The inner liner 10 adapted to this utility model typically already has holes for installing traditional underwater probes, which can be directly used as through holes 11. The screw hole 13 is an existing mounting structure in some inner liners 10. For inner liners 10 that do not originally have a screw hole 13, it can be added by modifying the manufacturing mold of the inner liner 10. Alternatively, the screw hole 13 can be installed on an existing inner liner 10 by tapping or other methods. Since most inner liners 10 are relatively thin, studs 12 can be added to provide the screw hole 13. These studs 12 can also be integrally formed onto the inner liner 10, or fixed to the inner liner 10 by welding or other methods.

[0032] As a preferred embodiment of this utility model, it may also have the following additional technical features:

[0033] In this embodiment, the sealing element 30 is elastic, thus enabling it to undergo a certain elastic deformation when the inner liner 10 and the pressure plate 21 are clamped together, ensuring a tight seal between the sealing element 30 and the inner liner 10, thereby further guaranteeing the sealing performance. In this embodiment, the sealing element 30 is made of silicone, which is easy to manufacture and provides excellent sealing performance, while also being less likely to contaminate the water inside the inner liner 10, making it safer. In other embodiments, the sealing element 30 may also be made of other commonly used elastic materials such as rubber, or non-elastic materials such as plastic; those skilled in the art can choose flexibly.

[0034] In this embodiment, one end of the sealing element 30 is provided with a sealing protrusion 32 that surrounds the temperature probe 22. The sealing protrusion 32 is used to abut against the outer wall of the inner liner 10, thereby ensuring tight contact between the sealing protrusion 32 and the outer wall of the inner liner 10, and avoiding large gaps between the sealing element 30 and the inner liner 10 due to factors such as processing errors or excessive contact area, which would affect the sealing effect. The sealing protrusion 32 is preferably an integral structure on the sealing element 30, which helps to further ensure the sealing performance. Of course, it can also be a ring element separately added to the sealing element 30.

[0035] In this embodiment, the front of the pressure plate 21 is provided with a first folding plate 211 for abutting against the outer wall of the inner liner 10, and the rear is provided with a second folding plate 212 for abutting against the outer wall of the inner liner 10. The first folding plate and the second folding plate 212 can play a positioning role by abutting against the outer wall of the inner liner 10 during the installation process, ensuring the accurate installation position of the underwater probe assembly, avoiding the underwater probe assembly from being misaligned, which would affect the sealing and temperature measurement effect, and also improving the firmness of the underwater probe assembly installation. It can effectively prevent the underwater probe assembly from being deformed or misaligned due to external forces during use, making it more reliable.

[0036] In this embodiment, there are two first folding plates 211 spaced apart from each other, and two second folding plates 212 spaced apart from each other, which can further improve the positioning and fixing effect. In this embodiment, the first folding plate 211 is located at the front end of the pressure plate 21, and the second folding plate 212 is located at the rear end of the pressure plate 21. In other embodiments, the setting position and distribution of the first folding plate 211 and the second folding plate 212 can also be adjusted as needed. Correspondingly, the first folding plate 211 and the second folding plate 212 can be one, three, four, or any other suitable number.

[0037] In this embodiment, the outer wall of the inner liner 10 has a first part 141 for abutting against the first folding plate 211 and a second part 142 for abutting against the second folding plate 212. There is a height difference between the first part 141 and the second part 142. The height difference between the tail of the first folding plate 211 and the tail of the second folding plate 212 is adapted to the height difference between the first part 141 and the second part 142. This can effectively ensure the balance of force on the underwater probe assembly, thereby ensuring the accuracy of the installation position and making it more reliable.

[0038] In this embodiment, the mounting hole 23 is an elongated hole, which can accommodate certain processing and assembly errors, as well as deformation caused by temperature changes during use, further facilitating assembly operations and making it more reliable.

[0039] In this embodiment, the pressure plate 21 is stepped, with its front part closer to the outer wall of the inner liner 10 than its rear part. This helps to accommodate the height difference between the stud 12 and the through hole 11, and also helps to improve the structural strength of the pressure plate 21 and reduce the deformation of the pressure plate 21.

[0040] In this embodiment, the temperature probe 22 is adapted to the through hole 11, which can reduce water leakage between the temperature probe 22 and the through hole 11 and improve the sealing effect. The temperature probe 22 is preferably fitted with the through hole 11 for easy assembly. The temperature probe 22 is riveted and fixed on the pressure plate 21 for easy assembly. In other embodiments, the temperature probe 22 can also be fixed on the pressure plate 21 by welding, snap-fitting or other suitable methods.

[0041] In this embodiment, the temperature probe 22 adopts a stainless steel shell, the sensor is set inside the shell, and a signal line 221 extends from the tail. This temperature probe 22 is widely used, and its structure and principle are well known to those skilled in the art. It will not be described in detail here. In other embodiments, the temperature probe 22 may also adopt other commonly used probe structures and is not limited to this.

[0042] In this embodiment, a positioning block 15 is protruding on the outer wall of the inner liner 10. The distance between the two second folding plates 212 is adapted to the positioning block 15. When the underwater probe assembly is installed on the inner liner 10, the positioning block 15 is inserted between the two second folding plates 212, which can position the underwater probe and limit the rotation of the underwater probe assembly, thus helping to improve the accuracy and firmness of the installation.

[0043] This invention is typically installed at the bottom of the inner liner 10, but can also be installed on the side wall of the inner liner 10. This invention can be applied to products that require heating liquids, such as electric kettles, health-preserving kettles, and coffee machines.

[0044] Without causing conflict, those skilled in the art can freely combine and use the above-mentioned additional technical features.

[0045] The above description is only a preferred embodiment of the present utility model. Any technical solution that achieves the purpose of the present utility model by essentially the same means shall fall within the protection scope of the present utility model.
