Abstract
Description
Technical Field
[0001] This utility model relates to the field of laboratory containers and utensils, and in particular to an insulated beaker. Background Technology
[0002] In laboratory scientific research and daily life, beakers are commonly used containers to hold various liquids and perform operations such as heating, dissolving, and evaporating. However, traditional beaker designs often lack effective temperature control and management, leading to excessively rapid heat transfer and an inability to effectively maintain the liquid temperature.
[0003] First, maintaining a stable experimental temperature is crucial for experimental results in a laboratory environment. However, due to their thermal conductivity, traditional beakers allow heat to easily transfer from the outside to the inside or vice versa, affecting temperature control and reducing the accuracy and stability of the experiment. Second, similar problems exist in daily life and industrial production. For example, in the preparation of coffee, tea, or other hot beverages, it is often desirable to maintain a certain temperature to preserve the taste of a hot drink. However, traditional beakers are ineffective at maintaining the temperature of beverages, causing them to lose heat quickly. Utility Model Content
[0004] To address the technical problems existing in the background art, this utility model proposes a heat-insulating beaker.
[0005] This invention discloses an insulated beaker, comprising a body with a heat-insulating structure made of phenolic resin on its side. Phenolic resin is a thermosetting plastic synthesized from phenolic and aldehyde compounds through a condensation reaction. It possesses excellent heat resistance, corrosion resistance, mechanical strength, and electrical insulation properties. This makes the beaker with the phenolic resin insulation layer highly safe and durable during use. Furthermore, phenolic resin is non-toxic and harmless, and will not release harmful substances that could affect the user's health. As a high-quality thermal resistance material, phenolic resin has good heat resistance, corrosion resistance, and excellent heat insulation performance, effectively blocking external heat transfer and thus maintaining a stable temperature of the liquid inside the beaker.
[0006] As a further optimization of this utility model, the heat insulation structure is a phenolic resin coating sprayed onto the inner and / or outer walls of the beaker. It should be noted that this phenolic resin coating is a coating containing phenolic resin material. This coating can be a phenolic resin-containing paint purchased from companies such as Jining Yitu Environmental Protection Materials Co., Ltd., Jinan Wantong Paint Sales Co., Ltd., and Jining Qibao Environmental Protection Technology Co., Ltd. After cleaning the side walls of the beaker, the phenolic resin solution is sprayed on. It should be noted that after the phenolic resin is sprayed onto the side walls of the beaker, a curing process is used to ensure its uniform adhesion to the side walls of the beaker. When this coating is located on the inner wall of the beaker, its transparent nature does not affect the observation of the liquid inside the beaker. The coating design makes beaker production simple, quick, and inexpensive, without increasing the complexity of use for the user.
[0007] Phenolic resin, as an excellent thermal resistance material, possesses outstanding heat resistance, corrosion resistance, mechanical strength, and good insulation properties. Its unique molecular structure makes it difficult for heat to pass through, thus making it an ideal material for manufacturing insulated cup sleeves. As a further optimization of this invention, the thermal insulation structure is a phenolic resin thermal insulation sleeve fitted over the outside of the cup body. To facilitate the fixing of the thermal insulation sleeve during molding, an elastic structure such as a rubber pad can be provided between the cup body and the thermal insulation sleeve. This elastic structure can be strip-shaped or raised.
[0008] For ease of use, as a further optimization of this utility model, the heat insulation sleeve is detachably fitted onto the outside of the cup body.
[0009] To further enhance the heat insulation effect, as a further optimization of this utility model, a heat insulation groove is opened in the middle of the heat insulation sleeve along its axial direction, that is, an air layer is introduced in the heat insulation sleeve. The structure of the air layer further enhances the heat insulation effect, specifically because the low thermal conductivity of the air layer can reduce the heat transfer through convection.
[0010] To increase the stability of the connection between the heat insulation sleeve and the cup body, as a further optimization of this utility model, a cover plate with a larger elastic coefficient than the heat insulation sleeve is detachably installed on the top of the heat insulation groove.
[0011] As a further optimization of this utility model, the cup body is made of high-temperature resistant glass, and an anti-slip groove is provided on the outside of the position where the cup body contacts the heat insulation sleeve.
[0012] As a further optimization of this utility model, an anti-slip pad can be detachably installed at the bottom of the cup body.
[0013] As a further optimization of this utility model, the anti-slip mat has a mounting groove, and the lower end of the cup body is located in the mounting groove.
[0014] As a further optimization of this utility model, the outer side of the beaker body has a radiation-shielding layer. Since thermal radiation is also a form of heat transfer, to reduce the impact of thermal radiation on the internal temperature of the beaker, coating with a radiation-shielding layer can reduce the transmission of thermal radiation. Specifically, the radiation-shielding layer can be a reflective layer or a radiation-shielding layer formed by coating a thermally resistive material.
[0015] The heat-insulating beaker proposed in this invention effectively blocks the transfer and loss of heat, thereby maintaining a stable temperature of the liquid inside the beaker.
[0016] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0023] like Figures 1-2The illustrated insulated beaker includes a body 1, specifically made of high-temperature resistant glass material as known in the art. The sides of the body 1 have an insulating structure made of phenolic resin. Phenolic resin is a thermosetting plastic synthesized from phenolic and aldehyde compounds through a condensation reaction. It possesses excellent heat resistance, corrosion resistance, mechanical strength, and electrical insulation. This makes the beaker with the phenolic resin insulating layer highly safe and durable during use. Furthermore, phenolic resin is non-toxic and harmless, and will not release harmful substances that could affect the user's health. As a high-quality thermal resistance material, phenolic resin has good heat resistance, corrosion resistance, and excellent thermal insulation properties, effectively blocking external heat transfer and thus maintaining a stable temperature of the liquid inside the beaker.
[0024] like Figure 1 As shown, in some embodiments, the heat insulation structure is specifically a phenolic resin coating 2 sprayed onto the inner and / or outer walls of the beaker 1. After cleaning the side walls of the beaker 1, the phenolic resin solution is sprayed on. It should be noted that after the phenolic resin is sprayed onto the side walls of the beaker, a curing process is used to ensure that it adheres evenly to the side walls of the beaker 1. When the coating is located on the inner wall of the beaker 1, its transparent nature does not affect the observation of the liquid inside the beaker. The coating design makes the beaker simple, quick, and inexpensive to manufacture, without increasing the complexity of use for the user.
[0025] like Figure 2 As shown in some embodiments, as a further optimization of this invention, the heat insulation structure is a heat insulation sleeve 3 made of phenolic resin, which is fitted onto the outside of the cup body 1. The structure of the heat insulation sleeve 3 makes it easy for the user to hold the cup body 1. Phenolic resin, as an excellent thermal resistance material, has excellent heat resistance, corrosion resistance, mechanical strength, and good insulation properties. Its unique molecular structure makes it difficult for heat to pass through, thus making it an ideal material for making heat-insulating cup sleeves.
[0026] It should be noted that in some embodiments, while setting the phenolic resin heat insulation sleeve 3, a phenolic resin heat insulation layer is also coated on the inner side of the cup body 1 to further increase its heat insulation effect.
[0027] For ease of use, the heat insulation sleeve 3 is preferably detachably fitted onto the outside of the cup body 1. The heat insulation sleeve 3 is designed to be detachable, allowing users to easily install and remove it as needed. In addition, the heat insulation sleeve 3 has a simple and elegant appearance and comes in a variety of colors to meet the personalized needs of different users.
[0028] like Figure 3As shown, in order to further enhance the heat insulation effect, preferably, a heat insulation groove 30 is opened in the middle of the heat insulation sleeve 3 along its axial direction, that is, an air layer is used in the heat insulation sleeve 3. The structure of the air layer further enhances the heat insulation effect, specifically because the low thermal conductivity of the air layer can reduce the heat transfer through convection.
[0029] like Figure 3 As shown, in order to increase the stability of the connection between the heat insulation sleeve 3 and the cup body 1, in some embodiments, preferably, a cover plate 4 with a larger elastic coefficient than the heat insulation sleeve 3 is detachably installed on the top of the heat insulation groove 30.
[0030] In order to increase the stability of the connection between the heat insulation sleeve 3 and the cup body 1 made of high temperature resistant glass, preferably, an anti-slip groove is provided on the outside of the contact position between the cup body 1 and the heat insulation sleeve 3. The anti-slip groove can be a texture made by the processing setting of the mold or the polishing treatment, thereby increasing the comfort of the cup body 1.
[0031] like Figure 4 As shown, in order to prevent the beaker from slipping during use, an anti-slip pad 5 is detachably installed on the bottom of the beaker body 1, thereby increasing the anti-slip effect of the beaker body 1.
[0032] Preferably, the anti-slip mat 5 has a mounting groove 50, and the lower end of the cup body 1 is located within the mounting groove 50. In some embodiments, the anti-slip mat 5 is preferably made of rubber material, and when the cup body 1 is placed in the mounting groove 50, the anti-slip mat 5 portion outside the mounting groove 50 is in a stretched state. The upper end face of the anti-slip mat 5 has a locking groove 51, and the bottom end of the heat insulation sleeve 3 has a locking protrusion 31, which matches the locking groove 51. This further increases the stability of the connection of the heat insulation sleeve 3.
[0033] In some embodiments, preferably, the outer side of the beaker 1 has a radiation-shielding layer. Since thermal radiation is also a form of heat transfer, to reduce the impact of thermal radiation on the internal temperature of the beaker, a radiation-shielding layer can be applied to reduce the transmission of thermal radiation. Specifically, the radiation-shielding layer can be a reflective layer or a radiation-shielding layer formed by coating a thermally resistive material.

Therefore, they should not be construed as limitations on this utility model.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.
