Description

Technical Field

[0001] The utility model belongs to the technical field of sewing machines, and in particular relates to a heat dissipation device for sewing machines. Background Art

[0002] With the widespread use of sewing machines in both household and industrial production, their operating efficiency and service life are receiving increasing attention. Sewing machines typically feature a closed internal structure to ensure stability during operation and isolation from the external environment. However, the enclosed space inside a sewing machine impedes air circulation, allowing heat to accumulate and resulting in suboptimal heat dissipation. This limitation is often manifested in the following ways:

[0003] The enclosed space within a sewing machine often lacks effective ventilation. Due to poor airflow, the heat generated during prolonged machine operation is difficult to dissipate quickly, causing internal temperatures to rise. This not only affects the performance of the sewing machine but can also affect the lifespan of its components. The lack of multiple air inlets and outlets prevents heat from being evenly dispersed and effectively dissipated. This is especially true during high-load operation or prolonged use, as the cooling device's air circulation is limited and insufficient, failing to meet actual requirements. Hot air accumulates internally, causing the cooling components to overheat, further impacting the machine's stability and performance. Utility Model Content

[0004] The purpose of this utility model is to address the above-mentioned technical problems and provide a sewing machine heat dissipation device that increases air inlets and outlets, improves the air flow path, improves the heat exchange effect of the radiator, and improves the heat dissipation stability and efficiency.

[0007] The heat dissipation mechanism is arranged in the installation chamber of the sewing machine body and is used to dissipate heat from the internal components of the sewing machine body;

[0008] The heat dissipation mechanism includes:

[0009] A connection frame is arranged inside the installation chamber;

[0010] There are two heat dissipation channels, which are respectively arranged on both sides of the connection frame. The heat dissipation channels pass through and extend out of the sewing machine body, and the heat dissipation channels are connected to the connection frame;

[0014] A filter is provided on the air guide housing;

[0015] The motor output shaft is connected to the fan.

[0016] In the above technical solution, further, a temperature sensor is provided inside the sewing machine body. The temperature sensor detects the temperature inside the sewing machine body in real time and transmits the detected temperature to the controller. The controller is electrically connected to the motor. The controller receives the temperature value of the sewing machine body detected by the temperature sensor and calculates the temperature value. When the temperature value exceeds a preset threshold level, the controller controls the motor operation state.

[0017] In any of the above technical solutions, further, sound-absorbing cotton is provided on the top of the two heat dissipation channels, and the two sound-absorbing cottons are located outside the air guide shell to absorb noise from the fan.

[0018] In any of the above technical solutions, further, a dustproof net is provided inside the heat dissipation channel.

[0019] In any of the above technical solutions, further, the dustproof net is arranged in the heat dissipation channel through a detachable structure, and the detachable structure is a disassembly mechanism.

[0020] In any of the above technical solutions, further, the disassembly mechanism includes:

[0022] The outer frame is arranged inside the heat dissipation channel, and one end of the outer frame extends into the slide-out slot and is slidably connected to the slide-out slot, and the dustproof net is arranged inside the outer frame;

[0023] The handle is arranged on the outside of the outer frame.

[0037] 4. The dustproof net can effectively prevent foreign matter from entering the heat dissipation channel, keeping the heat dissipation channel clean and unobstructed, and preventing mechanical failure or poor heat dissipation caused by these debris. The outer frame slides out of the heat dissipation channel through the sliding groove, thereby separating the dustproof net from the heat dissipation channel. Users should regularly remove the dustproof net to extend the service life of the sewing machine and improve work efficiency.

[0038] 5. Through the locking mechanism, the outer frame and dust screen can be firmly fixed in the heat dissipation channel to prevent them from loosening due to external force or vibration, thereby ensuring the heat dissipation effect and the stability of the equipment.

DETAILED DESCRIPTION

[0046] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0047] In the description of this application, it should be noted that the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn according to the actual proportional relationship. Technologies, methods and equipment known to ordinary technicians in the relevant fields may not be discussed in detail, but where appropriate, technologies, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, so once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0048] Example 1:

[0049] like Figure 1-Figure 3 As shown, this embodiment provides a heat dissipation device for a sewing machine, comprising:

[0050] A sewing machine body 1 is provided with a mounting chamber 2 therein;

[0051] The heat dissipation mechanism 3 is provided in the installation chamber 2 of the sewing machine body 1 and is used to dissipate heat from the internal components of the sewing machine body 1;

[0052] The heat dissipation mechanism 3 includes:

[0053] The connecting frame 31 is arranged inside the installation chamber 2;

[0054] There are two heat dissipation channels 32, which are respectively provided on both sides of the connection frame 31. The heat dissipation channels 32 pass through and extend out of the sewing machine body 1, and the heat dissipation channels 32 are connected to the connection frame 31;

[0055] The mounting groove 33 is provided on the top of the connection frame 31 and the heat dissipation channel 32, and the mounting groove 33 is connected to the connection frame 31 and the heat dissipation channel 32;

[0056] The air guide housing 34 is disposed in the mounting groove 33;

[0057] The fan 35 is disposed inside the air guide housing 34;

[0058] The filter 36 is provided on the air guide housing 34;

[0059] Motor 37 , the output shaft of motor 37 is connected to fan 35 .

[0060] In this technical solution, by providing multiple heat dissipation channels 32, the path and method of air circulation are improved, heat accumulation is avoided, and effective heat dissipation is ensured for the internal components of the sewing machine, thereby preventing overheating. The heat dissipation device adopts structures such as a connecting frame 31 and heat dissipation channels 32. The operation of the fan 35 makes the air flow faster and larger, which not only helps to discharge heat, but also increases the heat dissipation speed and maintains the long-term stable operation of the sewing machine. The design of this device ensures the high efficiency of the heat dissipation system, avoids overheating caused by poor heat dissipation, and thus avoids problems such as shutdown, burning or damage that may occur during the operation of the sewing machine, thereby improving the overall operating stability.

[0061] Working process: When the sewing machine is working normally, the fan 35 starts to rotate through the connection with the motor 37, driving the air flow, and the air enters the heat dissipation channel 32. Since the heat dissipation channel 32 is designed as two channels and passes through the sewing machine body 1, the air can flow along these two channels, thereby enhancing the efficiency of the air flow. After passing through the air guide shell 34, the air flows through the inside of the sewing machine body 1 to dissipate the heat of the electrical components inside the sewing machine body 1; when the heat inside the sewing machine body 1 needs to be discharged, the motor 37 drives the fan 35 to rotate in the opposite direction. The reverse rotation of the fan 35 will absorb the heat inside the sewing machine body 1 and effectively take away the heat inside the sewing machine. The heat dissipation channel 32 is connected to the connecting frame 31, and the air is directed to the outside during the flow, thereby ensuring the discharge of heat and the improvement of heat dissipation efficiency. During the air flow process, the air is filtered through the filter 36 to prevent external dust, debris, etc. from entering the heat dissipation device, avoiding clogging of the fan 35 and the heat dissipation channel 32. At the same time, the air circulation is smooth to avoid the degradation of heat dissipation performance caused by debris. Through the above series of air flow, heat exchange and discharge processes, the operating temperature of each component inside the sewing machine is kept within a reasonable range to avoid machine failure or performance degradation caused by high temperature.

[0062] like Figure 1 and Figure 2 As shown, in this embodiment, it is optimized that a temperature sensor 4 is provided inside the sewing machine body 1. The temperature sensor 4 detects the temperature inside the sewing machine body 1 in real time and transmits the detected temperature to the controller 5. The controller 5 is electrically connected to the motor 37. The controller 5 receives the temperature value of the sewing machine body 1 detected by the temperature sensor 4 and calculates the temperature value. When the temperature value exceeds the preset threshold level, the controller 5 controls the operating state of the motor 37.

[0063] In this technical solution, a temperature sensor 4 monitors the temperature inside the sewing machine body 1 in real time, ensuring that the sewing machine's operating environment remains within a reasonable temperature range at all times. The temperature data detected by the temperature sensor 4 is calculated and analyzed by a controller 5. If the temperature exceeds a preset threshold, the controller 5 automatically controls the operation of the fan 35 (motor 37), increasing the speed of the fan 35 or starting the fan 35 to improve heat dissipation efficiency and reduce the internal temperature. The controller 5 automatically adjusts the operation of the fan 35 based on temperature changes in the sewing machine body 1, allowing the heat dissipation device to flexibly meet the heat dissipation requirements of different operating environments. When the temperature is normal, the fan 35 may operate at a low speed or in standby mode, reducing energy consumption and noise. When the temperature rises, the fan 35 automatically accelerates to enhance heat dissipation. Intelligent temperature control prevents damage or performance degradation caused by overheating during high-load operation of the sewing machine. The controller 5 monitors temperature changes in real time, eliminating manual intervention and ensuring more precise and efficient operation of the heat dissipation system.

[0064] Working Process: Temperature sensor 4 continuously monitors the temperature inside the sewing machine body 1 and transmits the data in real time to controller 5. Controller 5 receives the temperature reading from sensor 4 and performs real-time calculations. If the detected temperature value is below a preset threshold, controller 5 maintains normal operation of fan 35. If the temperature value exceeds the threshold, controller 5 activates motor 37 and adjusts the operation of fan 35. Specifically, fan 35 accelerates, increasing air flow and heat dissipation, thereby lowering the internal temperature of the sewing machine. During this process, fan 35 quickly dissipates heat, ensuring that the temperature of internal components does not exceed the upper limit. When the temperature of sewing machine body 1 drops to a safe range, controller 5 automatically reduces the speed of fan 35, reducing noise and energy consumption, ensuring continued stable operation of the machine. If the temperature value remains excessively high and is not effectively controlled, controller 5 can further trigger an early warning system, alerting the operator to conduct inspections or adjustments to prevent damage or safety accidents caused by overheating.

[0065] like Figure 2 As shown, in this embodiment, the two heat dissipation channels 32 are optimized to have sound-absorbing cotton 6 on the top. The two sound-absorbing cottons 6 are located outside the air guide shell 34 to absorb noise from the fan 35 .

[0066] In the present technical solution, when the sewing machine is working at a high load, the heat dissipation of the fan 35 will generate a certain amount of noise, especially when the speed of the fan 35 is high, the noise is more obvious. By installing sound-absorbing cotton 6 on the top of the heat dissipation channel 32, the sound waves emitted by the fan 35 when it is in operation can be effectively absorbed, reducing the propagation of noise, thereby reducing the overall noise level of the sewing machine. For environments that require long-term continuous work, reducing noise helps to improve work efficiency and comfort. The use of sound-absorbing cotton 6 will not affect the air flow and heat dissipation effect, which not only ensures the heat dissipation effect, but also optimizes noise control. The sound-absorbing cotton 6 has good noise absorption performance, which can reduce the impact of noise pollution on the working environment, especially in noise-sensitive areas. This helps to maintain health and a quiet working environment. This effectively solves the problem of noise generated by the operation of the fan 35, ensuring that the sewing machine has proper noise control while maintaining efficient heat dissipation.

[0067] Example 2:

[0068] This embodiment provides a heat dissipation device for a sewing machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0069] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 6 As shown, in this embodiment, a dustproof net 7 is optimized and provided inside the heat dissipation channel 32 .

[0070] In the present technical solution, the provision of the dust net 7 can effectively prevent these external substances from entering the heat dissipation channel 32, keep the heat dissipation channel 32 clean and unobstructed, and prevent mechanical failures or poor heat dissipation caused by these debris, thereby protecting the internal components of the device, preventing the accumulation of dust and other debris, avoiding the blockage of the heat dissipation channel 32, ensuring that the fan 35 can operate normally and efficiently remove the heat generated internally, effectively reducing the accumulation of dust and debris, reducing the wear and corrosion of the internal parts of the heat dissipation channel 32, and extending the service life of the heat dissipation system and the sewing machine itself. The use of the dust net 7 can reduce the frequency of cleaning and maintenance inside the heat dissipation system. Since debris and dust are effectively blocked, users do not need to frequently clean the heat dissipation channel 32, which can save time and energy, and also reduce the risk of equipment damage caused by improper cleaning.

[0071] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 6 As shown, in this embodiment, the dustproof net 7 is optimized and arranged in the heat dissipation channel 32 through a detachable structure, and the detachable structure is a disassembly mechanism 8.

[0072] In this technical solution, dust, fibers, and other debris accumulated within the heat dissipation channel 32 can easily affect the efficiency of the heat dissipation system and the normal operation of the sewing machine. The removable design of the dust screen 7 allows the user to easily remove and clean the dust screen 7, thereby ensuring that the heat dissipation channel 32 is unobstructed and prevents dust and debris from clogging the channel or affecting the normal operation of the fan 35. The provision of a removal mechanism 8 allows the user to quickly and easily remove the dust screen 7, maintaining the efficiency of the heat dissipation system and the long-term stable operation of the sewing machine.

[0073] like Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, in this embodiment, the disassembly mechanism 8 is optimized and includes:

[0074] The slide-out slot 81 is provided on the side of the heat dissipation channel 32, and the slide-out slot 81 is connected to the heat dissipation channel 32;

[0075] The outer frame 82 is disposed inside the heat dissipation channel 32, and one end of the outer frame 82 extends into the slide-out slot 81 and is slidably connected to the slide-out slot 81. The dust screen 7 is disposed inside the outer frame 82;

[0076] The handle 83 is disposed outside the outer frame 82 .

[0077] In this technical solution, when the user needs to clean the dust net 7, the outer frame 82 can be easily pulled out through the handle 83 on the outer frame 82. The outer frame 82 slides out of the heat dissipation channel 32 through the sliding groove, so that the dust net 7 is detached from the heat dissipation channel 32. The user can take out the dust net 7, clean or replace it, and then reinstall it to ensure the normal operation of the heat dissipation system. Regularly disassemble the dust net 7 and clean the dust net 7 and the inside of the heat dissipation channel 32 to ensure that the heat dissipation system is not blocked, ensuring efficient heat dissipation and stable operation of the sewing machine. After cleaning, the user only needs to slide the outer frame 82 back into the heat dissipation channel 32 through the sliding groove 81 to complete the reinstallation of the dust net 7, making the cleaning and maintenance of the dust net 7 more convenient. In this way, the user can easily disassemble and install the dust net 7, ensuring that the dust and debris in the heat dissipation channel 32 are cleaned in time, thereby maintaining the efficiency and stability of the heat dissipation system, extending the service life of the sewing machine and improving work efficiency.

[0078] like Figure 1 、 Figure 4 and Figure 6 As shown, in this embodiment, the optimization further includes a locking mechanism 9, which includes:

[0079] Ear plates 91 are provided at the upper and lower ends of the outer side of the outer frame 82;

[0080] A through hole 92 is provided on the ear plate 91;

[0081] Connecting plates 93 are provided at the upper and lower ends of the outer sides of the heat dissipation channel 32;

[0082] A locking hole 94 is provided on the connecting plate 93 and is connected to the through hole 92;

[0083] The insertion rod 95 is slidably disposed between the through hole 92 and the locking hole 94;

[0084] A pull plate 96 is provided at one end of the insertion rod 95;

[0085] Thread 97, provided on the insertion rod 95;

[0086] The nut 98 cooperates with the thread 97 on the insertion rod 95 .

[0087] In the present technical solution, the outer frame 82 and the dust screen 7 can be firmly fixed in the heat dissipation channel 32 through the locking mechanism 9 to prevent them from loosening due to external force or vibration, thereby ensuring the heat dissipation effect and the stability of the equipment. The design of the locking mechanism 9 avoids the accidental loosening or falling off of the dust screen 7 during use, thereby improving the safety of the equipment during operation. Although the locking mechanism 9 is added, the design does not complicate the user's disassembly process. The user can still easily disassemble and install the dust screen 7, ensuring the convenience of maintenance. The locking mechanism 9 improves the durability of the heat dissipation device through its reliable fixing function and reduces the risk of poor heat dissipation or other failures due to the loosening of the dust screen 7.

[0088] Working process: The through-hole 92 of the ear plate 91 on the outer frame 82 mates with the locking hole 94 of the connecting plate 93 on the outside of the heat dissipation channel 32. The insertion rod 95 is inserted by sliding between the through-hole 92 and the locking hole 94, completing the insertion operation. When the insertion rod 95 is fully inserted into the through-hole 92 and the locking hole 94, the pull plate 96 provides support for one end of the insertion rod 95. The user then rotates the nut 98 so that the nut 98 engages with the thread 97 on the insertion rod 95, securing the insertion rod 95 and preventing it from sliding out of the locking hole 94. At this point, the locking mechanism 9 firmly secures the outer frame 82 to the heat dissipation channel 32, and the dust screen 7 is firmly fixed within the heat dissipation channel 32. To remove the dust screen 7, the user first loosens the nut 98 to release the connection between the thread 97 and the insertion rod 95. Then, pull the pull plate 96, which causes the insertion rod 95 to slide out of the locking hole 94. The outer frame 82 can then be slid out of the heat dissipation channel 32, completing the removal of the dust screen 7. After cleaning or replacing the dustproof net 7, the user puts the dustproof net 7 back into the outer frame 82 and inserts it into the heat dissipation channel 32, completes the docking of the insertion rod 95 and the lock hole 94 through the locking mechanism 9, and rotates the nut 98 to lock the dustproof net 7 again to ensure that it is firmly installed. This ensures the stability of the dustproof net 7 during operation and prevents the dustproof net 7 from loosening or falling off due to external force or vibration. At the same time, it can still maintain simplicity during disassembly and maintenance, thereby enhancing the reliability and safety of the dustproof net 7 and improving the user's maintenance efficiency and convenience.

[0089] The embodiments of the present application are described above in conjunction with the accompanying drawings. Unless there is a conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of this application, ordinary technicians in this field can also make many forms without departing from the purpose of this application and the scope of protection of the claims, all of which are within the protection of this application.
