Description

Technical Field

[0001] The utility model relates to the technical field of heating equipment, in particular to a glass heating container. Background Art

[0002] In the prior art, all-glass milk mixers or all-glass heaters are popular among consumers because their main bodies (including the body, handle, etc.) are made of glass. Compared with stainless steel heating containers, glass heating containers can significantly reduce the problem of heavy metal residues and have significant benefits for drinking water health. When controlling the water boiling temperature of such products, NTC temperature sensors (thermistors) are usually used.

[0003] Traditional NTC temperature sensors are usually installed in a metal sleeve that is fixed on the heating base. However, this design has two main problems: first, the metal sleeve is affected by the temperature of the heating plate, which may lead to inaccurate temperature sensing; second, when the NTC temperature sensor can move along the axial direction of the metal sleeve or the position of the heating container is deflected when it is placed in the heating base, the metal sleeve and the surface of the heating container may become point contact, further reducing the accuracy of temperature sensing.

[0004] In order to improve this problem, some products try to place the NTC temperature sensor directly on the kettle body, in direct contact with the outer wall of the kettle body, in the hope of improving the temperature sensing accuracy. However, this design requires the user to place the kettle body in a fixed position on the base and align the connection terminal of the NTC temperature sensor with the conductive terminal on the base when placing the kettle body. This is inconvenient to operate and is prone to connection failure due to improper placement. Utility Model Content

[0046] Reference Figure 1-Figure 10 , which is an embodiment of the glass heating container of the utility model.

[0047] like Figure 1 As shown, the glass heating container includes a heating pot assembly 100 and a base assembly 200. The base assembly 200 is used to heat the heating pot assembly 100, and the two adopt a split structure design, which makes the heating pot assembly 100 more flexible and convenient in operation.

[0048] See also Figure 2-Figure 6 The heating kettle assembly 100 includes a glass kettle body 110 and an annular sleeve 120 .

[0049] The transparent appearance of the glass pot body 110 not only adds to the beauty of the product, but also allows the user to observe the state of the liquid in the pot at any time.

[0050] The annular sleeve 120 is sleeved and fixed on the lower part of the glass kettle body 110. The annular sleeve 120 is a non-metallic part, and the annular sleeve 120 is provided with a temperature sensing module 130 that is closely attached to the glass kettle body 110 and a conductive connector 140 that is electrically connected to the temperature sensing module 130.

[0051] See also Fig.10 The base assembly 200 includes a base 210 having a receiving groove 211 , a heating module (not shown) for heating the bottom of the glass pot body 110 , and a control module (not shown) disposed inside the base 210 .

[0052] The base 210 is provided with a receiving groove 211 which can accommodate the lower part of the heating pot assembly 100 and allow the heating pot assembly 100 to rotate freely 360° on the base 210 .

[0053] An annular electrical connector 212 is disposed on the inner side wall of the accommodating groove 211 ; when the heating pot assembly 100 is placed on the base assembly 200 , the annular electrical connector 212 is electrically connected to the conductive connector 140 .

[0054] In the above-mentioned glass heating container, the temperature sensing module 130 is fixed to the side wall of the glass kettle body 110 through the annular sleeve 120, and can maintain close contact with the glass kettle body 110 to improve the accuracy of temperature sensing; at the same time, an annular electrical connector 212 is provided on the base 210, which can achieve stable and reliable electrical conduction with the temperature sensing module 130 on the glass kettle body 110. The glass kettle body 110 can be placed on the base 210 at will without worrying about position deflection, which greatly improves the user's convenience.

[0055] In this embodiment, the lower part of the glass pot body 110 has an annular recess, the annular sleeve 120 is sleeved on the annular recess, and the outer side surface of the annular sleeve 120 is flush with the outer side surface of the glass pot body 110, so that the glass pot body 110 maintains its overall aesthetics.

[0056] In this embodiment, if Figure 7-Figure 9 As shown, the temperature sensing module 130 includes an NTC temperature sensor 131 and a first elastic member 132 .

[0057] An installation groove is provided on the inner wall of the annular sleeve 120 , and the NTC temperature sensor 131 is embedded and installed in the installation groove.

[0058] The first elastic member 132 , preferably a compression spring, is disposed between the NTC temperature sensor and the bottom surface of the mounting groove, so that the NTC temperature sensor remains in close contact with the outer wall of the glass kettle body 110 .

[0059] Furthermore, the NTC temperature sensor 131 is wrapped with insulating paper on the outside, and the insulating paper wraps the NTC temperature sensor in a tightly compressed state to exclude air in the insulating paper, reduce the influence of thermal resistance on the detected temperature, and improve the accuracy of temperature sensing detection.

[0060] The conductive connector 140 includes a conductive column, which is fixed and protrudes from the outer wall of the annular sleeve 120. The conductive column can be connected to the NTC temperature sensor through a wire. A lead groove can be opened on the inner wall of the annular sleeve 120 for wiring. In this embodiment, three conductive columns are provided, which are arranged vertically at intervals. The annular electrical connector 212 protrudes from the inner wall of the receiving groove 211 of the base 210, and three corresponding intervals are provided.

[0061] The glass kettle body 110 of the present embodiment includes an integrally formed kettle body and a handle. A longitudinally extending heat insulating member 150 is provided on the side wall of the kettle body of the glass kettle body 110. The heat insulating member 150 is arranged on the inner side of the handle. The heat insulating member 150 is made of high temperature resistant plastic or rubber material. By arranging the heat insulating member 150 on the inner side of the handle, the user is prevented from being scalded by the kettle body when holding the handle. In addition, a heat insulating material can be further arranged on the outer side of the handle. A heat insulating gasket can also be arranged on the inner side of the annular sleeve 120 to prevent the annular sleeve from overheating.

[0062] Since the conductive connector 140 is protruding from the annular sleeve 120, for the sake of aesthetic appearance, the conductive connector 140 is arranged just below the connection position between the handle and the kettle body, so that the heating kettle assembly 100 has a symmetrical structure as a whole.

[0063] Furthermore, if Figure 6 As shown, in order to prevent the glass heating container from drying out when the glass kettle body 110 is dry, a water level detection module 160 is provided on the annular sleeve 120 and is in close contact with the glass kettle body 110. The water level detection module 160 is spaced apart from the temperature sensing module 130, and the water level detection module 160 is electrically connected to the conductive connector 140, thereby achieving communication with the base assembly 200.

[0064] Specifically, Fig. 9 As shown, the water level detection module 160 includes a liquid level sensor 161 and a second elastic member 162. The second elastic member 162 is preferably a compression spring, which is used to keep the liquid level sensor 161 in close contact with the outer wall of the glass kettle body 110.

[0065] The water level detection module 160 uses non-contact liquid level detection, and the liquid level sensor 161 can detect the water level by laser, infrared detection, or by measuring capacitance value. Preferably, the water level detection module 160 uses the detection method of measuring capacitance value, that is, the liquid level sensor 161 is a capacitive liquid level sensor 161, which has high accuracy and can detect the liquid level more accurately. The compression spring of the capacitive liquid level sensor is embedded in the annular sleeve 120, which can keep the capacitive liquid level sensor 161 in close contact with the outer wall of the glass pot body 110 to ensure detection accuracy.

[0066] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the above embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the above embodiments, or to replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions claimed to be protected by the present invention.
