Technical Field

[0001] The present application relates to the technical field of battery manufacturing, and in particular to a composite hose. Background Art

[0002] Electrolyte is an important component of the battery. During transportation, electrolyte often blocks the transportation pipeline.

[0003] The above is merely a description of the relevant technology and does not mean that the applicant admits that the above is the prior art.

[0004] In view of this, it is necessary to provide a new composite hose to solve or at least alleviate the above-mentioned technical defects. Utility Model Content

[0005] In view of the above problems, the present application provides a composite hose, aiming to improve the technical problem of electrolyte blocking the transport pipeline in the related art.

[0006] According to some embodiments of the present application, the present application provides a composite hose, including a hollow tube, a heating rope and an energy supply component, wherein a transport pipeline is formed inside the hollow tube, the hollow tube and the heating rope are intertwined, and the energy supply component is electrically connected to the heating rope.

[0007] By arranging the hollow tube and the heating rope to be intertwined, the energy supply component and the heating rope are electrically connected, the heating rope can be heated by the energy supply component. When the temperature of the heating rope is increased, the temperature of the hollow tube can be increased, thereby reducing the risk of solidification of the electrolyte in the transport pipeline due to the temperature being lower than the melting point during transportation. At the same time, the use of an intertwined design can reduce the amount of heating rope used and reduce the production cost.

[0008] In some embodiments, the heating rope includes a heating element and a heat-conducting layer wrapping the heating element, the heating element is electrically connected to the energy supply element, and the heat-conducting layer is intertwined with the outer wall of the hollow tube.

[0009] By setting up a heating rope including a heating element and a heat-conducting layer wrapping the heating element, the heat-conducting layer and the outer wall of the hollow tube are intertwined with each other, the heating element is heated and heated by the energy supply element, and the heating element transfers heat to the hollow tube that is in contact and intertwined with the heat-conducting layer through the heat-conducting layer. The heat transfer area between the heating rope and the hollow tube can be increased, the temperature of the hollow tube can be made more uniform, and the phenomenon of local temperature being too high or too low can be avoided.

[0010] In some embodiments, the heating element includes a metal wire electrically connected to the energy supply element, and the thermal conductive layer includes a silicone thermal conductive layer wrapping the metal wire.

[0011] The heating element is made of metal wire, which can generate heat when current passes through it, and the metal element itself has a certain plasticity and can be bent and wound. The heat-conducting layer is made of silicone, which can transfer heat. The silicone is flexible, which can be easily wound with the hollow tube and reduce the risk of scratching the hollow tube.

[0012] In some embodiments, the heating rope is evenly wound around the hollow tube, the first winding knots of the hollow tube are evenly and evenly spaced, and / or the second winding knots of the heating rope are evenly and evenly spaced.

[0013] By arranging the winding knots of the heating rope to be evenly spaced, and / or the winding knots of the hollow tube to be evenly spaced, the heating rope and the hollow tube can be evenly wound together, so that the heating rope heats the hollow tube evenly, reducing the risk of the electrolyte being at least partially solidified due to local low temperature in the hollow tube caused by uneven heating.

[0014] In some embodiments, the heating rope is evenly wound around the hollow tube, and a first pitch of the heating rope is equal to a second pitch of the hollow tube.

[0015] By setting the first pitch of the heating rope and the second pitch of the hollow tube to be equal, the heating rope can heat the hollow tube evenly, reducing the risk of the electrolyte solidifying at least partially due to local low temperature of the hollow tube caused by uneven heating.

[0016] In some embodiments, the energy supply component includes a power cord and a plug connected to the power cord, and the power cord electrically connects the plug and the heating rope.

[0017] By arranging an energy supply component to wrap the power cord and the plug, an external power source is introduced through the plug to heat the heating rope, and the method of obtaining electric energy is simple and convenient.

[0018] In other embodiments, the energy supply component includes a battery, and the battery is electrically connected to the heating rope.

[0019] By connecting the battery to the heating rope, there is no need for an external power source, which reduces dependence on the external environment and makes the application scenarios of the composite hose more diverse.

[0020] In some embodiments, the composite hose further comprises a control panel electrically connected to the energy supply component, wherein the control panel is used to adjust the heating temperature of the heating rope.

[0021] By setting up a control panel, the heating temperature can be displayed, and the heating temperature can be adjusted according to the actual flow conditions of the electrolyte or the types of different electrolytes.

[0022] In some embodiments, the composite hose further includes a protective layer, which is wrapped around the heating rope and the outer circumference of the hollow tube.

[0023] By setting a protective layer on the outer periphery of the heating rope and the hollow tube, it can play a protective role or a heat preservation role depending on the material of the protective layer. It is also possible to set a constant temperature environment through the control panel.

[0024] In some embodiments, the protective layer includes a heat insulation layer, and the heat insulation layer is wrapped around the heating rope and the outer circumference of the hollow tube.

[0025] By providing a heat insulating layer, heat is preserved in the cavity of the heat insulating layer, heat loss is reduced, and temperature control is made more controllable.

[0026] In some embodiments, the protective layer includes a flexible layer, and the flexible layer is wrapped around the heating rope and the outer circumference of the hollow tube.

[0027] A flexible layer is provided to wrap around the heating rope and the outer periphery of the hollow tube to provide protection. Meanwhile, the flexible layer is made of a flexible material, which can reduce the bending modulus of the composite hose and improve the bending performance.

[0028] In some embodiments, the protective layer includes a heat insulating layer and a flexible layer wrapped around the heat insulating layer, and the heat insulating layer is wrapped around the heating rope and the hollow tube.

[0029] By setting up the heat insulation layer, the heat is kept in the cavity of the heat insulation layer, reducing heat loss and making the temperature control more controllable. By setting up the protective layer, it is wrapped around the heating rope and the outer periphery of the hollow tube to play a protective role. At the same time, the protective layer is made of flexible material, which can reduce the bending modulus of the composite hose and improve the bending performance.

[0030] In some embodiments, the flexible layer is a bellows.

[0031] By setting the flexible layer as a bellows and adopting a corrugated structure design, the modulus can be reduced, the bending strain capacity can be improved, and it is convenient for bending and storage.

[0032] In some embodiments, the hollow tube is a flexible bellows.

[0034] In some embodiments, a first opening and a second opening are respectively formed at both ends of the hollow tube, and the first opening and the second opening are respectively connected to the transport pipeline.

[0035] By providing the first opening and the second opening, extraction and injection of electrolyte can be achieved.

[0053] At present, from the perspective of market development, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as military equipment and aerospace and other fields. With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding.

[0054] As the demand for power batteries increases, more and more power batteries are being made. The electrolyte plays a vital role as the "blood" of power batteries. During the production process, the electrolyte needs to be added through the transport pipeline. During this process, the transport pipeline is often blocked. To this end, the applicant has carefully developed and found that in order to achieve accurate weighing of the electrolyte, the crystalline electrolyte is usually heated to a liquid state, and then weighed by a syringe pump for extraction and injection, which causes the transport pipeline to be blocked during the extraction and injection process. After further research, the applicant found that the blockage was caused by the solidification of the electrolyte. Specifically, in the commonly used formulas of electrolytes, some commonly used solvents or additives have a high melting point and will appear crystalline at room temperature. Such as ethylene carbonate (abbreviated as EC, melting point: 35-38°C), vinylene carbonate (abbreviated as VC, melting point: 19-22°C), fluoroethylene carbonate (abbreviated as FEC, 18°C), 1,3-propane sultone (abbreviated as PS, 30-33°C). For these solvents or additives with higher melting points, if the method of heating them to liquid state and then weighing is adopted, during the extraction and injection process, the temperature of the transport pipeline may be low, lower than the melting point of the solvent or additive, which may cause the solvent or additive to solidify in the transport pipeline and cause blockage of the transport pipeline.

[0055] To this end, the present application provides a composite hose.

[0056] Reference Figure 1 and Figure 2 According to some embodiments of the present application, the present application provides a composite hose 100, including a hollow tube 10, a heating rope 20 and an energy supply component 30, a transport pipeline is formed inside the hollow tube 10, the hollow tube 10 and the heating rope 20 are intertwined, and the energy supply component 30 is electrically connected to the heating rope 20.

[0057] The hollow tube 10 is hollow, and a transport pipeline is formed inside for transporting electrolyte. The electrolyte can be added from one end of the hollow tube 10, and the electrolyte can be output from the other end. Specifically, the hollow tube 10 can be connected to an injection pump for weighing the electrolyte extraction and injection. The energy supply component 30 is a component that can provide energy to the heating rope 20. The energy supply component 30 provides energy to the heating rope 20 so that the temperature of the heating rope 20 increases and generates heat. For example, the energy supply component 30 can provide electrical energy to the heating rope 20 so that the temperature of the heating rope 20 increases and generates heat. The heating rope 20 and the outer tube wall of the hollow tube 10 are intertwined with each other, and heat can be transferred to the hollow tube 10, so that the temperature of the hollow tube 10 increases, and then the electrolyte in the transport pipeline can be heated or kept warm, so that the electrolyte transported from the transport pipeline in the hollow tube 10 is not easy to solidify and block. The hollow tube 10 and the heating rope 20 are intertwined with each other, which means that the two are intertwined like two braided ropes, and the two are arranged in a spiral line shape. This not only allows the hollow tube 10 to be heated evenly, but also reduces the risk of uneven temperature heating. In addition, compared with the prior art of wrapping a heating sleeve around the hollow tube 10, or winding multiple turns of a heating element around the outer wall of a straight hollow tube 10, the number of heating ropes 20 required by this embodiment is relatively small.

[0058] By arranging the hollow tube 10 and the heating rope 20 to be intertwined, the energy supply component 30 is electrically connected to the heating rope 20, and the heating rope 20 can be heated by the energy supply component 30. When the temperature of the heating rope 20 is increased, the temperature of the hollow tube 10 can be increased, thereby reducing the risk of solidification of the electrolyte in the transport pipeline due to the temperature being lower than the melting point during transportation. At the same time, the mutually intertwined design can reduce the amount of the heating rope 20 used and reduce the production cost.

[0059] In some embodiments, the heating rope 20 includes a heating element and a heat-conducting layer wrapping the heating element, the heating element is electrically connected to the energy supply element 30 , and the heat-conducting layer is intertwined with the outer wall of the hollow tube 10 .

[0060] The heating element can generate heat when the energy supply element 30 supplies power and current passes through the heating element, and the temperature of the heating element rises. Generally, a good conductor of electricity is used. The heat-conducting layer is wrapped around the outer periphery of the heating element. The heat-conducting layer and the heating element can both be in strip shape, so that they can be conveniently intertwined with the hollow tube 10. The heat-conducting layer is heated by the heat of the heating element, so that the temperature of the heat-conducting layer rises. Then, the heat is transferred to the hollow tube 10 intertwined and contacted with it through the heat-conducting layer through heat transfer, which can increase the heat transfer area.

[0061] By setting the heating rope 20 to include a heating element and a heat-conducting layer wrapping the heating element, the heat-conducting layer and the outer wall of the hollow tube 10 are intertwined, the heating element is heated and heated by the energy supply component 30, and the heating element transfers heat to the hollow tube 10 that is in contact and intertwined with the heat-conducting layer through the heat-conducting layer. The heat transfer area between the heating rope 20 and the hollow tube 10 can be increased, so that the temperature of the hollow tube 10 is more uniform, avoiding the phenomenon of local excessive temperature or excessive low temperature.

[0062] In some embodiments, the heating element includes a metal wire electrically connected to the energy supply element 30, and the thermal conductive layer includes a silicone thermal conductive layer wrapping the metal wire.

[0063] Metal wire refers to a filament made of metal, or it can also be a strip. Metal is a good conductor of heat. Since metal has electrical resistance, according to Joule's law, when an electric current passes through the metal wire, it will heat up and rise in temperature. The specific metal wire can be copper wire or aluminum wire. The thermal conductive layer needs to have two properties. One is that it can transfer heat. The thermal conductive layer is heated by the metal wire. After the temperature of the thermal conductive layer rises, the heat is transferred to the temperature of the hollow tube 10 through heat transfer, so that the electrolyte flows in an environment higher than its melting point, thereby reducing the possibility of the electrolyte flowing through the hollow tube 10 solidifying due to too low a temperature. Second, it is finally made of a flexible material, which can avoid scratching or abrasions on the hollow tube 10, and it can also be easily entangled with the hollow tube 10.

[0064] The heating element is made of metal wire, which can generate heat when current passes through it to increase its own temperature, and the metal element itself has a certain plasticity and can be bent and wound. The heat-conducting layer is made of silicone, which can transfer heat, and the silicone is flexible, which can be easily wound with the hollow tube 10 and reduce the risk of scratching the hollow tube 10.

[0065] Reference Figure 2 In some embodiments, the heating rope 20 is evenly wound around the hollow tube 10, the second winding knots 21 of the heating rope 20 are evenly and evenly spaced, and / or the first winding knots 13 of the hollow tube 10 are evenly and evenly spaced.

[0066] The winding knot refers to the knot viewed from one side after the hollow tube 10 and the heating rope 20 are wound together. Figure 2As shown, between two adjacent second winding knots 21 of the heating rope 20 is the first winding knot 13 of the hollow tube 10, and between two adjacent first winding knots 13 of the hollow tube 10 is the second winding knot 21 of the heating rope 20. The second winding knots 21 of the heating rope 20 are evenly and evenly spaced, so that the length and width of the first winding knots 13 of the hollow tube 10 between the adjacent second winding knots 21 of the heating rope 20 are the same. The first winding knots 13 of the hollow tube 10 are evenly and evenly spaced, so that the length and width of the second winding knots 21 of the heating rope 20 between the two adjacent first winding knots 13 of the hollow tube 10 are the same, so that uniform winding is achieved, and the heating rope 20 can heat the hollow tube 10 evenly.

[0067] By arranging the second winding knots 21 of the heating rope 20 to be evenly spaced, and / or the first winding knots 13 of the hollow tube 10 to be evenly spaced, the heating rope 20 and the hollow tube 10 can be evenly wound together, so that the heating rope 20 can evenly heat the hollow tube 10, thereby reducing the risk of partial solidification of the electrolyte due to local low temperature of the hollow tube 10 caused by uneven heating.

[0068] Reference Figure 2 In some embodiments, the heating rope 20 is evenly wound around the hollow tube 10, and a first pitch of the heating rope 20 is equal to a second pitch of the hollow tube 10.

[0069] In fact, when the heating rope 20 and the hollow tube 10 are intertwined, when viewed separately, the heating rope 20 and the hollow tube 10 both extend in a spiral line. The pitch here is the length of the spiral line after the spiral line is wound around the spiral center line once. Here, the first pitch of the heating rope 20 and the second pitch of the hollow tube 10 are set to be equal, so that uniform winding is achieved, and the heating rope 20 can heat the hollow tube 10 uniformly.

[0070] By setting the first pitch of the heating rope 20 and the second pitch of the hollow tube 10 to be equal, the heating rope 20 can heat the hollow tube 10 evenly, reducing the risk of the electrolyte at least partially solidifying due to the local temperature of the hollow tube 10 being too low due to uneven heating.

[0071] The energy supply component 30 can be in various forms. In theory, any energy supply component 30 that can provide energy to the heating rope 20 to increase the heating temperature of the heating rope 20 is within the scope of protection of this application. Specifically, the energy supply component 30 includes at least the following two forms:

[0072] Reference Figure 1 In some embodiments, the energy supply component 30 includes a power cord 31 and a plug 32 connected to the power cord 31 , and the power cord 31 electrically connects the plug 32 and the heating rope 20 .

[0073] The plug 32 is used to connect to an external power source, which may be a socket installed on a wall, or a power strip connected from the socket, and is powered by connecting to the external power source through the plug 32. It should be noted that both ends of the heating rope 20 are connected to the circuit, so that current can pass through the heating rope 20 to heat it. Specifically, when the heating rope 20 includes a heating element and a heat-conducting layer, the power cord 31 is electrically connected to the heating element.

[0074] By providing an energy supply member 30 to wrap the power cord 31 and the plug 32, an external power source is introduced through the plug 32 to heat the heating rope 20, and the method of obtaining electric energy is simple and convenient.

[0075] Reference Figure 3 In other embodiments, the energy supply component 30 includes a battery 33, and the battery 33 is electrically connected to the heating rope 20.

[0076] The storage battery 33 refers to a battery that stores electrical energy. The size of the storage battery 33 can be selected according to actual needs, such as 2V, 5V, 7V or 10V. The heating rope 20 is connected to the circuit by connecting the storage battery 33 to the heating rope 20. Specifically, when the heating rope 20 includes a heating element and a heat-conducting layer, the storage battery 33 is electrically connected to the heating element.

[0077] By providing a storage battery 33 connected to the heating rope 20, there is no need for an additional external power supply, which reduces dependence on the external environment and makes the application scenarios of the composite hose 100 more diverse.

[0078] Reference Figure 1 or Figure 3 In some embodiments, the composite hose 100 further includes a control panel 50 electrically connected to the energy supply member 30 , and the control panel 50 is used to adjust the heating temperature of the heating rope 20 .

[0079] The control panel 50 may include a housing, a display screen mounted on the housing, and adjustment buttons disposed on the housing. The display screen may be used to display the set heating temperature set at the time, such as the temperature of the hollow tube 10 or the heating temperature of the heating rope 20. The adjustment button may adjust the heating temperature by controlling the magnitude of the input current of the energy supply member 30. Specifically, the control panel 50 may control the heating rope 20 to achieve temperature regulation within the range of room temperature (e.g., 20°C) to 100°C.

[0080] By providing the control panel 50 , the heating temperature can be displayed, and the heating temperature can be adjusted according to the actual flow conditions of the electrolyte or the types of different electrolytes.

[0081] In some embodiments, the composite hose 100 further includes a protective layer, which is wrapped around the heating rope 20 and the outer circumference of the hollow tube 10 .

[0082] The heating rope 20 and the hollow tube 10 are intertwined to form a rope-like object, and the protective layer is also formed into a hollow sleeve. The cavity in the protective layer is used to accommodate the heating rope 20 and the hollow tube 10, which can play a protective role. If the protective layer is made of a heat-insulating material, it can also play a heat-insulating role.

[0083] By providing a protective layer on the outer periphery of the heating rope 20 and the hollow tube 10, a protective effect or a heat preservation effect can be achieved according to the material of the protective layer. A constant temperature environment can also be set through the control panel 50.

[0084] In some embodiments, the protective layer includes a heat insulation layer 60 , and the heat insulation layer 60 is wrapped around the heating rope 20 and the outer circumference of the hollow tube 10 .

[0085] The heat-insulating layer 60 can be made of a heat-insulating material, because the heating rope 20 and the hollow tube 10 will emit heat when their temperatures rise, and heat is always transferred from an object with a high temperature to an object with a low temperature. If the heating rope 20 and the hollow tube 10 are directly exposed to the air, the heat loss will be relatively large. Therefore, a heat-insulating layer 60 can be provided on the outside to wrap the heating rope 20 and the hollow tube 10 to reduce heat loss and save energy. In addition, in order to enhance the overall flexibility of the composite hose 100, the heat-insulating layer 60 here can also be made of a flexible material, such as the heat-insulating layer 60 can be a flexible aerogel insulation layer. Specifically, the heat-insulating layer 60 can be a hollow sleeve.

[0086] By providing the heat insulating layer 60 , heat is preserved in the cavity of the heat insulating layer 60 , heat loss is reduced, and temperature control is made more controllable.

[0087] In some embodiments, the protective layer includes a flexible layer 70 , and the flexible layer 70 is wrapped around the heating rope 20 and the outer circumference of the hollow tube 10 .

[0088] The flexible layer 70 here can also be made of flexible materials, and at the same time needs to have certain wear resistance and bending resistance, so as to better play a protective role. Specifically, the protective layer can be a hollow sleeve.

[0089] The flexible layer 70 is provided to wrap around the heating rope 20 and the outer periphery of the hollow tube 10 to provide protection. Meanwhile, the flexible layer 70 is made of a flexible material, which can reduce the bending modulus of the composite hose 100 and improve the bending performance.

[0090] In some embodiments, the protective layer includes a heat insulating layer 60 and a flexible layer 70 wrapped around the outer periphery of the heat insulating layer 60 , and the heat insulating layer 60 is wrapped around the outer periphery of the heating rope 20 and the hollow tube 10 .

[0091] The heat-insulating layer 60 can be made of a heat-insulating material, because the heating rope 20 and the hollow tube 10 will emit heat when the temperature rises, and heat is always transferred from an object with a high temperature to an object with a low temperature. If the heating rope 20 and the hollow tube 10 are directly exposed to the air, the heat loss will be relatively large. Therefore, a heat-insulating layer 60 can be provided on the outside to wrap the heating rope 20 and the hollow tube 10 to reduce heat loss and save energy. In addition, in order to improve the overall flexibility of the composite hose 100, the heat-insulating layer 60 here can also be made of a flexible material, such as the heat-insulating layer 60 can be a flexible aerogel heat-insulating layer 60. Specifically, the heat-insulating layer 60 can be a hollow sleeve. The protective layer here can also be made of a flexible material, and at the same time it needs to have certain wear resistance and bending resistance, so as to better play a protective role. Specifically, both the heat-insulating layer 60 and the protective layer can be hollow sleeves.

[0092] By providing the heat insulating layer 60, the heat is stored in the cavity of the heat insulating layer 60, the heat loss is reduced, and the temperature control is more controllable. By providing the protective layer, the protective layer is wrapped around the heating rope 20 and the outer periphery of the hollow tube 10 to play a protective role. At the same time, the protective layer is made of a flexible material, which can reduce the bending modulus of the composite hose 100 and improve the bending performance.

[0093] In some embodiments, the flexible layer 70 is a bellows.

[0094] The flexible layer 70 can be a flexible polymer protective sleeve with a corrugated structure. The corrugated structure is beneficial to reducing the bending modulus of the overall composite infusion tube and is conducive to bending.

[0095] By setting the flexible layer 70 as a bellows and adopting a corrugated structure design, the modulus can be reduced, the bending strain capacity can be improved, and it is convenient for bending and storage.

[0096] In some embodiments, the hollow tube 10 is a flexible bellows.

[0097] The hollow tube 10 is a flexible corrugated tube, which can increase the bendability of the composite hose 100 and facilitate various complex usage scenarios and storage. The hollow tube 10 has an inner layer of flexible polymer material that can resist corrosion from the electrolyte. The material mainly includes polyethylene terephthalate (PET), polypropylene (PP) and a flexible fluorine-containing polymer.

[0098] By setting the hollow tube 10 as a corrugated tube and adopting a corrugated structure design, the modulus can be reduced, the bending strain capacity can be improved, and storage is convenient.

[0099] In some embodiments, a first opening 11 and a second opening 12 are respectively formed at both ends of the hollow tube 10 , and the first opening 11 and the second opening 12 are respectively connected to the transport pipeline.

[0100] The first opening 11 and the second opening 12 may be a liquid inlet and a liquid outlet, respectively, and a syringe pump or a syringe may be connected to one of the openings to achieve extraction and injection of electrolyte.

[0101] By providing the first opening 11 and the second opening 12 , extraction and injection of electrolyte can be achieved.

[0102] According to some embodiments of the present application, the present application provides a composite hose 100, including a hollow tube 10, a heating rope 20, a control panel 50 and an energy supply part 30, wherein a transport pipeline is formed inside the hollow tube 10, the heating rope 20 includes a metal wire and a heat-conducting silicone layer wrapped outside the metal wire, the energy supply part 30 includes a plug 32 and a power cord 31, the power cord 31 is electrically connected to the plug 32 and the metal wire, the heat-conducting silicone layer of the heating rope 20 and the outer wall of the hollow tube 10 are intertwined and evenly distributed at equal distances, and a heat-insulating layer 60 is provided on the outer jacket of the braided structure composed of the heating rope 20 and the hollow tube 10, and the heat-insulating layer 60 can be a flexible aerogel sleeve, and a flexible layer 70 is provided on the outer jacket of the heat-insulating layer 60, and the flexible layer 70 can be a polymer bellows, and the hollow tube 10 can also use a polymer bellows with certain corrosion resistance. This embodiment can avoid the electrolyte from being blocked due to coagulation at low temperature, and can also save the use of the heating rope 20 and reduce the manufacturing cost.

[0103] Specifically, during use, firstly, the energy supply part 30 of the composite hose 100 is turned on to enter the operating state, and the control panel is adjusted from 50 to 60°C. After the internal temperature of the composite hose 100 reaches 60°C, it is connected to the injection pump. The internal temperature here can be the measured temperature of the outer wall of the hollow tube 10, the temperature of the heating rope 20, the temperature of the inner cavity of the heat insulation layer 60, or the temperature of the electrolyte. Experimental operation: After the high melting point electrolyte solvent EC (melting point 35°C-38°C) is heated from solid to liquid, the liquid is pumped through the injection pump. The extracted liquid flows through the hollow tube 10 of the composite hose 100 and is transferred to the liquid preparation container bottle. During the entire infusion process, the electrolyte is in liquid and flows smoothly without blockage.
