Description

Technical Field

[0001] This utility model relates to the field of battery processing equipment technology, and in particular to a battery formation equipment. Background Technology

[0002] Battery formation is the first charging process of a battery after electrolyte filling. This process activates the active materials in the battery, thus activating it. Battery formation is generally carried out within formation equipment.

[0003] Formation equipment typically includes a formation cabinet, which holds the batteries to be formed. The temperature inside the formation cabinet is usually maintained within a high temperature range. Controlling the temperature inside the formation cabinet usually requires a heating room to supply hot water to the formation cabinet through pipes to maintain the temperature within the required range.

[0004] However, the method of supplying hot water to the forming cabinet through the heating room of the plant to maintain the temperature inside the forming cabinet within a high temperature range requires connecting a long pipeline between the heating room and the forming cabinet. This results in a long path for the hot water to flow from the heating room to the forming cabinet, making it impossible to regulate the temperature inside the forming cabinet in a timely manner, thus leading to poor temperature control within the forming cabinet. Utility Model Content

[0005] This application discloses a battery formation device that can timely regulate the formation temperature in the formation cabinet, effectively improving the control effect of the formation temperature.

[0006] To achieve the above objectives, embodiments of this application disclose a battery formation apparatus, comprising:

[0007] A formation cabinet has a formation chamber for placing batteries to be formed, and the formation cabinet also has a heat exchange chamber that communicates with the formation chamber;

[0008] A temperature control component is located inside the heat exchange chamber. The temperature control component includes an electric heater, a heat exchanger, and a fan. The heat exchanger contains a liquid medium. The electric heater is used to heat the liquid medium. The heat exchanger can exchange heat with the gas in the heat exchange chamber to generate heated air. The fan is used to drive the heated air to circulate between the heat exchange chamber and the formation chamber.

[0009] Optionally, the formation chamber and the heat exchange chamber are separated by a partition, the partition being provided with an air inlet and an air outlet, and the fan is configured to drive the heating air into the formation chamber through the air inlet and back to the heat exchange chamber through the air outlet.

[0010] Optionally, the fan is disposed at the air inlet, and the air outlet side of the fan is disposed towards the chemical formation chamber; and / or, the fan is disposed at the air outlet, and the air outlet side of the fan is disposed towards the heat exchange chamber.

[0011] Optionally, the air inlet is located near the bottom of the formation chamber, and the air outlet is located near the top of the formation chamber.

[0012] Optionally, the formation chamber has an air guide disposed opposite to the air inlet, the air guide being used to guide the heated airflow to a region inside the formation chamber away from the partition.

[0013] Optionally, the heat exchanger is disposed adjacent to the air outlet and is disposed opposite to the air outlet along the air outlet direction.

[0014] Optionally, the temperature control component further includes an air duct, which is disposed within the heat exchange chamber. The heat exchanger is located within the air duct and is used to heat the gas within the air duct. The air outlet of the air duct is connected to the air inlet, and the air inlet of the air duct is connected to the air outlet.

[0015] Optionally, the temperature control assembly further includes a heating tube, which is connected to the heat exchanger via a circulation pipeline to allow the liquid medium to circulate between the heating tube and the heat exchanger. An electric heater is connected to the heating tube and is used to heat the liquid medium within the heating tube.

[0016] Optionally, a pump is provided on the circulation pipeline, the pump being configured to provide flow power to the liquid medium so that the liquid medium circulates between the heating tube and the heat exchanger.

[0017] Optionally, the electric heater includes any one of a flanged heating tube, a finned heating tube, and a quartz heating tube.

[0018] Compared with the prior art, this application has at least the following beneficial effects:

[0019] In this application, the formation cabinet has a heat exchange chamber, and the temperature control component is located within the heat exchange chamber. Specifically, the electric heater and heat exchanger in the temperature control component are both located within the heat exchange chamber, effectively shortening the flow path of the liquid medium, reducing heat loss during flow, and improving heat utilization. Furthermore, the electric heater can directly heat the liquid medium, allowing its temperature to rise rapidly. This enables the heat exchanger to heat the gas within the heat exchange chamber more promptly, thereby heating the formation chamber more quickly. This effectively improves the control of the formation temperature within the chamber, ensuring a more stable maintenance of the temperature at the required high-temperature formation stage, ultimately contributing to improved battery formation quality.

[0020] By using a fan to drive the heating air to circulate between the heat exchange chamber and the formation chamber, the heated gas can circulate rapidly between the formation chamber and the heat exchange chamber, so as to control the temperature in the formation chamber more timely and efficiently, which is conducive to maintaining the formation temperature in the formation chamber and thus improving the formation quality of the battery.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

These terms are primarily for the purpose of better describing this invention and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0036] Furthermore, in addition to indicating direction or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this utility model according to the specific circumstances.

[0037] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this utility model based on the specific circumstances.

[0038] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0039] Battery formation is the first charging process of a battery after electrolyte filling. This process activates the active materials in the battery, thus activating it. Battery formation is generally carried out in a formation device, where the battery to be formed is placed in a sealed formation cabinet, and the temperature inside the cabinet is controlled within a relatively high temperature range.

[0040] The formation temperature primarily affects the formation effect by influencing the viscosity and conductivity of the electrolyte and the ion diffusion rate of the electrode materials. Higher formation temperatures result in lower electrolyte viscosity, higher electrolyte conductivity, and faster ion diffusion rates in the electrode materials, leading to less polarization and better formation. However, excessively high formation temperatures can damage the structure and composition of the already formed solid electrolyte interfacial film. Furthermore, since the electrolyte is an organic solvent solution, excessively high temperatures will accelerate the volatilization of low-boiling-point components, negatively impacting the formation effect. Therefore, the formation temperature needs to be maintained within a relatively high range, such as around 35°C, 45°C, or 60°C.

[0041] However, in related technologies, hot water is typically supplied to the forming tank from a heating room in the plant to heat the gas inside and maintain the temperature within the forming tank within the required range. However, the heating room and the forming tank are usually quite far apart, requiring long pipelines to connect them. This results in a long path for the hot water to flow from the heating room to the forming tank, making it difficult to regulate the temperature within the forming tank in a timely manner, leading to poor temperature control within the forming tank.

[0042] Based on this, this application discloses a battery formation device that can timely regulate the formation temperature in the formation cabinet, effectively reduce heat loss, improve heat utilization, and enhance the regulation effect of the formation temperature in the formation cabinet.

[0043] The technical solution of this application will be described in detail below with reference to specific embodiments and accompanying drawings.

[0044] This application provides a battery formation device, such as... Figures 1-4As shown, the device includes a formation chamber 1 and a temperature control component 2. The formation chamber 1 has a formation chamber 11 for placing the battery to be formed. The formation chamber 1 also has a heat exchange chamber 12 connected to the formation chamber 11. The temperature control component 2 is located in the heat exchange chamber 12 and includes an electric heater 21, a heat exchanger 22 and a fan 23. The heat exchanger 22 contains a liquid medium. The electric heater 21 is used to heat the liquid medium. The heat exchanger 22 can exchange heat with the gas in the heat exchange chamber 12 to generate heating air. The fan 23 is used to drive the heating air to circulate between the heat exchange chamber 12 and the formation chamber 11.

[0045] In this embodiment, the temperature control component 2 is located inside the heat exchange chamber 12. The heat exchanger 22 within the temperature control component 2 contains a liquid medium, and the electric heater 21 heats the liquid medium to continuously and stably heat it to the desired temperature. The heat exchanger 22 can exchange heat with the gas inside the heat exchange chamber 12 to generate heating air, ensuring continuous and stable heating of the gas inside the heat exchange chamber 12. The formation chamber 11 is connected to the heat exchange chamber 12, and the fan 23 drives the heating air to circulate between the heat exchange chamber 12 and the formation chamber 11. This allows the heated gas to flow towards the formation chamber 11, thus increasing the temperature within the formation chamber 11. Simultaneously, the gas inside the formation chamber 11 can also flow towards the heat exchange chamber 12, where it is heated by the heat exchanger 22 to form new heating air. This heating air then flows back towards the formation chamber 11, thereby maintaining the temperature within the formation chamber 11 within the desired formation temperature range.

[0046] Because the temperature control component 2 is located in the heat exchange chamber 12, that is, both the electric heater 21 and the heat exchanger 22 in the temperature control component 2 are located in the heat exchange chamber 12, the flow path of the liquid medium is effectively shortened, the heat loss of the liquid medium during the flow process is reduced, and the utilization rate of heat is improved. Moreover, the liquid medium can be directly heated by the electric heater 21, which allows the temperature of the liquid medium to rise relatively quickly. This enables the heat exchanger 22 to heat the gas in the heat exchange chamber 12 in a timely manner, thereby heating the formation chamber 11 in a timely manner and regulating the temperature in the formation chamber 11. This effectively improves the regulation effect of the formation temperature in the formation chamber 11, allowing the temperature in the formation chamber 11 to be maintained relatively stably at the required high-temperature formation temperature, which in turn benefits the formation cabinet 1 in improving the formation quality of the battery.

[0047] The fan 23 drives the heating air to circulate between the heat exchange chamber 12 and the formation chamber 11, which allows the heated gas to circulate quickly between the formation chamber 11 and the heat exchange chamber 12. This enables more timely and efficient temperature control within the formation chamber 11, which is beneficial for maintaining the formation temperature within the formation chamber 11 and thus improving the formation quality of the battery.

[0048] The liquid medium mentioned above can be water, aqueous solution of ethylene glycol, aqueous solution of glycerol, etc., and is not limited here.

[0049] The heat exchanger 22 can be any of the following: a jacketed heat exchanger, a mixing heat exchanger, a fluid-connected indirect heat exchanger, and a duplex heat exchanger, and is not limited to any of them.

[0050] Alternatively, the electric heater 21 can heat the liquid medium through resistance heating, that is, by using an electric current to generate heat in the heating element to heat the liquid medium. This allows for timely temperature control of the liquid medium, enabling the heat exchanger 22 to heat the gas in the heat exchange chamber 12 more promptly. Consequently, the temperature in the formation chamber 11 can be regulated more quickly, maintaining the temperature within the required formation temperature range, which is beneficial for improving the formation quality of the battery in the battery formation equipment 10. Of course, in other embodiments, the electric heater 21 can also heat the liquid medium through electromagnetic induction heating, that is, using the principle of electromagnetic induction to convert electrical energy into heat energy, which is energy-saving and environmentally friendly.

[0051] Optionally, when the electric heater 21 heats the liquid medium by resistance heating, the electric heater 21 may include any one of flange heating tube, finned heating tube and quartz heating tube, so that the electric heater 21 has high heating efficiency for the liquid medium, which is conducive to timely control of the temperature in the formation chamber 11, thereby helping to maintain the temperature in the formation chamber 11 within the required formation temperature range.

[0052] The aforementioned formation cabinet 1 may include a cabinet body, with the formation chamber 11 and heat exchange chamber 12 both located within the cabinet body. The formation chamber 11 and heat exchange chamber 12 may be arranged adjacent to each other within the cabinet body, so that the heated gas in the heat exchange chamber 12 can flow into the formation chamber 11 in a timely manner, which is beneficial for temperature control within the formation chamber 11. Of course, the formation chamber 11 and heat exchange chamber 12 may also be arranged at intervals, so as to facilitate the layout of the formation chamber 11 and heat exchange chamber 12 within the formation cabinet 1 according to requirements.

[0053] Optionally, such as Figure 2 , Figure 5 and Figure 6 As shown, when the formation chamber 11 and the heat exchange chamber 12 are arranged adjacent to each other, a partition 3 can be provided inside the cabinet to separate the formation chamber 11 and the heat exchange chamber 12. That is, the formation chamber 11 and the heat exchange chamber 12 are separated by the partition 3. The partition 3 is provided with an air inlet 31 and an air outlet 32. The fan 23 is configured to drive the heating air to enter the formation chamber 11 through the air inlet 31 and return to the heat exchange chamber 12 through the air outlet 32.

[0054] This allows the gas in the heat exchange chamber 12 to be heated and then flow into the formation chamber 11 in a timely manner, further reducing heat loss and facilitating temperature control within the formation chamber 11, thereby improving the formation effect of the battery by the formation cabinet 1.

[0055] The wind speed of the fan 23 can be adjusted according to the temperature in the formation chamber 11 to control the flow rate of the gas flowing into the formation chamber 11, thereby regulating the temperature in the formation chamber 11 and improving the temperature uniformity in each area of ​​the formation chamber 11.

[0056] The fan 23 can be any of the following types: centrifugal fan, axial fan, mixed-flow fan, cross-flow fan, etc. There is no limitation here, and the specific type can be selected according to actual needs.

[0057] The aforementioned fan 23 can be located near the heat exchange chamber 12, or near the air inlet 31 or at the air inlet 31, or near the air outlet 32 ​​or at the air outlet 32. No limitation is made here.

[0058] Optionally, such as Figure 2 As shown, the fan 23 is disposed at the air inlet 31, and the air outlet side of the fan 23 is disposed towards the formation chamber 11; and / or, the fan 23 is disposed at the air outlet 32, and the air outlet side of the fan 23 is disposed towards the heat exchange chamber 12.

[0059] Therefore, the fan 23 not only enables the heated gas to flow quickly into the formation chamber 11, but also enables the heated gas to flow into a wider space within the formation chamber 11 and to flow quickly into the heat exchanger 22. This allows for more timely and efficient temperature control within the formation chamber 11, which is beneficial for maintaining the formation temperature within the formation chamber 11 and thus improving the formation quality of the battery.

[0060] The fan 23 can be installed on the air inlet 31 or the air outlet 32, or it can be installed on both the air inlet 31 and the air outlet 32. There is no limitation here, and the specific configuration can be determined according to the actual situation.

[0061] For example, taking the fan 23 installed at the air inlet 31 as an example, the number of fans 23 can be one or more, and there is no limitation here.

[0062] When there are multiple fans 23, the number of air inlets 31 can be one or more, and this is not limited. When there is only one air inlet 31, it can extend horizontally, and multiple fans 23 can be mounted on a mounting bracket on the wall of the heat exchange chamber 12. The multiple fans 23 are positioned opposite to the air inlet 31, and the outlet sides of the multiple fans 23 all face the formation chamber 11. When there are multiple air inlets 31, the number of air inlets 31 can correspond one-to-one with the number of fans 23, that is, each air inlet 31 can be equipped with one fan 23, and the outlet sides of the fans 23 all face the formation chamber 11. In addition, the multiple air inlets 31 can be arranged horizontally so that the heating air can flow through the fans 23 to a larger spatial area of ​​the formation chamber 11, making it easier for the temperature in each area of ​​the formation chamber 11 to be basically uniform.

[0063] Optionally, such as Figure 2 As shown, the air inlet 31 is located near the bottom of the formation chamber 11, and the air outlet 32 ​​is located near the top of the formation chamber 11.

[0064] Therefore, the gas heated by the heat exchanger 22 can flow through the air inlet 31 into the space at the bottom of the formation chamber 11 to heat the gas in the space at the bottom of the formation chamber 11. At the same time, the temperature of the gas flowing into the formation chamber 11 rises because it is higher than the temperature of the gas in the formation chamber 11, so that the heated gas can gradually fill the entire formation chamber 11. This makes the temperature in each area of ​​the formation chamber 11 basically uniform, which is beneficial to improving the formation quality of the battery.

[0065] Meanwhile, the gas flowing from the air inlet 31 to the formation chamber 11 will exchange heat with the lower-temperature gas in the formation chamber 11 as it rises, causing its temperature to drop. The cooled gas, as well as the gas near the top space of the formation chamber 11, can flow through the air outlet 32 ​​to the heat exchange chamber 12, where it will be heated by the heat exchanger 22. The heated gas can then flow back to the formation chamber 11 through the air inlet 31. In this way, by continuously circulating the gas between the formation chamber 11 and the heat exchange chamber 12, the temperature uniformity of each area in the formation chamber 11 can be improved, which is more conducive to improving the quality of battery formation.

[0066] It is understandable that when the heat exchange chamber 12 and the formation chamber 11 are arranged in a horizontal direction, the air inlet 31 is located near the bottom of the formation chamber 11, and the air inlet 31 is also located near the bottom of the heat exchange chamber 12. The air outlet 32 ​​is located near the top of the formation chamber 11, and the air outlet 32 ​​is also located near the top of the heat exchange chamber 12.

[0067] Optionally, the formation chamber 11 has an air guide that is disposed opposite to the air inlet 31. The air guide is used to guide the heating airflow to the area inside the formation chamber 11 away from the partition 3.

[0068] Therefore, by guiding the airflow through the air guide, the heated gas can flow to more areas within the formation chamber 11, which is beneficial for the temperature uniformity of each area within the formation chamber 11, and thus better for the formation effect of the battery by the formation cabinet 1.

[0069] The air guide can be implemented in various ways. In one possible implementation, the air guide can be an air guide plate extending in a horizontal direction. The air guide plate can be provided with multiple air guide holes so that the heating air entering the formation chamber 11 can flow along the air guide plate and flow towards the top of the formation chamber 11 through the multiple air guide holes, making the structure of the air guide simple and easy to implement.

[0070] In another implementation, the air guide can also be an air duct. The air duct extends along the direction of moisture, and multiple air vents arranged horizontally can be provided on the wall of the air duct so that the heating air can flow along the air duct in a direction away from the partition 3. During the flow, it can flow to other areas of the formation chamber 11 through multiple air vents. Thus, the area to which the heating air can flow can be adjusted by the number and position of the air vents, which effectively improves the temperature uniformity of each area in the formation chamber 11.

[0071] Optionally, such as Figure 2 and Figure 3 As shown, the heat exchanger 22 is located near the air outlet 32 ​​and is positioned opposite to the air outlet 32 ​​along the air outlet direction.

[0072] Therefore, the gas flowing from the formation chamber 11 to the heat exchange chamber 12 can be heated by the heat exchanger 22 after passing through the air outlet 32, so that the gas at the air outlet 32 ​​can have a higher temperature. This effectively reduces the probability of unheated gas in the heat exchange chamber 12 flowing to the formation chamber 11 through the air outlet 32, which is beneficial for the temperature control in the formation chamber 11.

[0073] In addition, such as Figure 7 As shown, the temperature control component 2 also includes an air duct 24, which is disposed in the heat exchange chamber 12. The heat exchanger 22 is located in the air duct 24 and is used to heat the gas in the air duct 24. The air outlet of the air duct 24 is connected to the air inlet 31, and the air inlet of the air duct 24 is connected to the air outlet 32.

[0074] Therefore, the heat exchanger 22 can heat only the gas in the air duct 24, and the heated gas can flow to the formation chamber 11 through the air inlet 31 along the air duct 24, avoiding the heated gas from flowing to other areas in the heat exchange chamber 12. This allows most of the heated gas to flow to the formation chamber 11, which is beneficial to improving the utilization rate of heat.

[0075] The electric heater 21 can be installed inside the cavity of the air duct 24 or outside the air duct 24, and there is no limitation on this. In addition, when the electric heater 21 is located outside the air duct 24, the electric heater 21 can be installed on the cabinet of the formation cabinet 1 or on the air duct 24, and there is no limitation on this either.

[0076] In addition, the cross-sectional shape of the duct 24 can be circular, rectangular, or elliptical, and there are no restrictions here. It can be set according to the actual situation.

[0077] In some embodiments, such as Figure 3 As shown, the temperature control component 2 also includes a heating tube 25, which is connected to the heat exchanger 22 through a circulation pipe 26 so that the liquid medium circulates between the heating tube 25 and the heat exchanger 22. An electric heater 21 is connected to the heating tube 25 and is used to heat the liquid medium in the heating tube 25.

[0078] Therefore, by connecting the electric heater 21 to the heating tube 25, the installation of the electric heater 21 is facilitated. Since the heating tube 25 is also located in the heat exchange chamber 12, the length of the circulation pipe 26 connecting the heating tube 25 and the heat exchanger 22 can be shortened, and the flow path of the liquid medium between the heating tube 25 and the heat exchanger 22 can be shortened. This not only reduces costs but also reduces heat loss of the liquid medium during flow. As a result, the temperature of the liquid medium flowing from the heating tube 25 to the heat exchanger 22 can be easily controlled, and the heating temperature of the gas by the heat exchanger 22 can also be easily controlled. Consequently, the temperature regulation in the formation chamber 11 can be made easier.

[0079] The diameter of the heating tube 25 can be larger than that of the circulation pipe 26, so that the heating tube 25 can hold more liquid medium, so that the electric heater 21 can heat more liquid medium, so that the amount of liquid medium flowing to the heat exchanger 22 can be more sufficient, so that the heat exchanger 22 can exchange heat with more gas, which is beneficial to improving the temperature control efficiency.

[0080] In addition, the circulation pipeline 26 may include an inlet pipe and an outlet pipe. The inlet pipe is connected between the outlet of the heating pipe 25 and the inlet of the heat exchanger 22, and the outlet pipe is connected between the inlet of the heating pipe 25 and the outlet of the heat exchanger 22. The structure is simple and the pipeline is short, which effectively reduces the cost.

[0081] Optionally, such as Figure 3 As shown, a pump 27 may be installed on the circulation pipeline 26. The pump 27 is configured to provide the power for the flow of the liquid medium so that the liquid medium circulates between the heating pipe 25 and the heat exchanger 22.

[0082] This effectively increases the flow rate of the liquid medium and the circulation rate of the liquid medium between the heating tube 25 and the heat exchanger 22, so that the heat exchanger 22 can heat the gas in the heat exchange chamber 12 in a timely manner, which is conducive to timely temperature control in the formation chamber 11.

[0083] Pump 27 can be either a pressure pump or a circulation pump, and there is no limitation on this. For example, when pump 27 is a pressure pump, the volume of pump 27 can be smaller, which reduces the space occupied in the formation cabinet 1 and avoids the battery formation equipment 10 occupying a large area due to the large volume of pump 27.

[0084] In addition, a valve can be installed on the circulation pipeline 26 to adjust and control the flow rate of the liquid medium flowing to the heat exchanger 22, which facilitates the adjustment of the temperature of the gas in the heat exchange chamber 12 heated by the heat exchanger 22.

[0085] The valve can be a solenoid valve, ball valve, gate valve, butterfly valve, etc., and there is no limitation here.

[0086] In some embodiments, the battery formation apparatus 10 may further include a temperature detection element disposed in the formation chamber 11 for detecting the temperature in the formation chamber 11, and the temperature detection element is electrically connected to the electric heater 21.

[0087] Therefore, the temperature inside the formation chamber 11 can be monitored more accurately by the temperature detection device. When the temperature inside the formation chamber 11 is not within the temperature range required for high-temperature formation, the heating temperature of the electric heater 21 on the liquid medium can be adjusted in time, which helps to maintain the temperature inside the formation chamber 11 within the temperature range required for high-temperature formation, thereby enabling the battery to be formed in the formation cabinet 1 to have a better formation effect.

[0088] The temperature detection component can be a temperature sensor, a thermometer, or a temperature detector; there is no limitation on this.

[0089] In other embodiments, the formation cabinet 1 is provided with a vent that is connected to the formation chamber 11. The vent is configured to connect to the outside when the temperature inside the formation chamber 11 is higher than a preset temperature.

[0090] It should be noted that the preset temperature mentioned above refers to the highest temperature suitable for high-temperature formation, which can be 38℃, 49℃, 60℃, etc., and is not limited here.

[0091] Therefore, when the temperature inside the formation chamber 11 is higher than the preset temperature, the heat inside the formation chamber 11 can be released to the outside through the ventilation port in a timely manner, so that the temperature inside the formation chamber 11 can be cooled down to a temperature range suitable for high-temperature formation in a more timely manner. Moreover, the structure is simple and easy to implement.

[0092] When the temperature inside the formation chamber 11 is lower than the preset temperature, the vent can be closed; when the temperature inside the formation chamber 11 is higher than the preset temperature, the vent can be open.

[0093] The opening and closing of the vents can be achieved manually, or an automatically opening and closing valve can be installed at the vents. The valve can be electrically connected to a temperature detection device so that when the temperature detection device detects that the temperature inside the formation chamber 11 is higher than the preset temperature, the valve can be automatically opened so that the air inside the formation chamber 11 can be exchanged with the outside air through the vents, thereby releasing the heat inside the formation chamber 11 to the outside and regulating the temperature inside the formation chamber 11.
