Description

Technical Field

[0001] This utility model relates to the field of snow melting equipment technology, specifically to a snow melting machine. Background Technology

[0002] Existing snow melting machines typically include a base and a material cylinder mounted on the base. The base contains a power unit and a refrigeration unit. Inside the material cylinder is an evaporator and a stirring paddle fitted outside the evaporator. The beverage is placed in the material cylinder, cooled by the evaporator, and stirred by the stirring paddle to achieve uniform processing.

[0003] In one existing design, the feeding tank is a single, integral structure with a feeding channel only at the top. Users can then add liquid beverages into the tank through this channel. However, this design has the following problems: due to the small diameter of the feeding channel, only liquid beverages can be added through this channel, preventing users from adding special ingredients such as fruits. This significantly limits the types of food that can be processed by the slush machine. Furthermore, the narrow feeding channel makes cleaning the tank extremely difficult, creating cleaning dead spots and potentially leading to safety and hygiene issues.

[0004] In another existing solution, a large feeding port is opened at the top of the material cylinder, and a material cover is further installed at the feeding port to cover it. This solution greatly facilitates the user in feeding the material cylinder. However, users are prone to direct contact with the stirring paddle during the operation of the snow melting machine, which poses a risk. Therefore, existing solutions usually also have a safety switch installed in the base, which can only be triggered and the snow melting machine started when the material cover is installed in place. However, in further implementation of the product, the applicant discovered that the above solution has special usage scenarios where the user installs the material cover separately, or installs the material cover before the material cylinder is fully installed, thereby triggering the safety switch and starting the snow melting machine. In this case, the stirring paddle will be suddenly turned on, creating a danger and making the snow melting machine a safety hazard. Utility Model Content

[0005] The purpose of this utility model is to provide a safe snow melting machine to solve the technical problems of existing snow melting machines, such as inconvenience in feeding and difficulty in cleaning when using a small feeding channel, and the risk of accidental triggering and start-up when using a large feeding port, which are caused by products not being fully installed.

[0006] To solve the above-mentioned technical problems, this utility model provides a safe snow melting machine, including a base and a refrigeration component and a power component disposed within the base, and a processing module disposed on the upper part of the base. The processing module includes a material cylinder that surrounds the refrigeration chamber of the component with the base, an evaporator and a stirring paddle disposed within the material cylinder, and a cylinder cover covering the top opening of the material cylinder. The stirring paddle is sleeved on the outer periphery of the evaporator. The refrigeration component includes a compressor and a condenser that are in fluid communication with the evaporator. The power component passes through the evaporator to drive the stirring paddle. The base is also provided with a safety switch and a linkage structure that can trigger the safety switch. When the material cylinder and the cylinder cover are installed in place simultaneously, the linkage structure is activated and the safety switch is triggered.

[0007] The slush machine described in this application features an open feeding port at the top of its feeding cylinder. This allows users to quickly add ingredients and also accommodates special foods such as fruits, expanding the slush machine's beverage processing range and enhancing the user experience. Furthermore, the open design facilitates cleaning, and the simple structure of the cylinder minimizes cleaning dead spots, making it easier for users to remove the cylinder and lid for washing. A linkage mechanism ensures that the safety switch and slush machine are only triggered when the cylinder and lid are simultaneously and reliably installed in place. If either the cylinder or lid is not properly installed, the user cannot start the slush machine, ensuring safer, more stable, and reliable operation. In particular, even a skilled user cannot effectively start the slush machine by operating the lid or cylinder alone, preventing the risk of children accidentally activating the machine through the lid.

[0008] As a preferred embodiment, the linkage structure includes a first trigger position and a second trigger position. The material cylinder pushes the first trigger position, and the cylinder cover pushes the second trigger position. The linkage structure triggers the safety switch when the first trigger position and the second trigger position are pushed simultaneously.

[0009] The linkage structure is further provided with a first trigger position and a second trigger position, wherein the material cylinder can push the first trigger position and the cylinder cover can push the second trigger position. The safety switch can only be triggered when the first trigger position and the second trigger position of the linkage structure are pushed at the same time. The safety switch cannot be triggered when either the first trigger position or the second trigger position is pushed, thereby ensuring that the snow melting machine is safer to use.

[0010] As a preferred embodiment, the material cylinder is provided with a first push column, the cylinder cover is provided with a second push column, the machine base is provided with a connecting rod, the machine base is provided with a first insertion hole for the first push column to pass through and a second insertion hole for the second push column to pass through, the first push column and the second push column extend into the machine base to simultaneously push the connecting rod and trigger the safety switch.

[0011] A connecting rod is further provided inside the base, and a first insertion hole and a second insertion hole are provided on the outer shell of the base. When the material cylinder is installed in place, the first push post is inserted into the first insertion hole and pushes the connecting rod; when the cylinder cover is installed in place, the second push post is inserted into the second insertion hole and pushes the connecting rod at the same time. Only then can the connecting rod trigger the safety switch, thus avoiding the safety risk caused by triggering the safety switch when only the material cylinder or only the cylinder cover is installed in place.

[0012] As a preferred embodiment, the linkage includes a first linkage that cooperates with a first push post and a second linkage that cooperates with a second push post, wherein the first linkage and the second linkage are linked to trigger the safety switch.

[0013] The system further incorporates a first link and a second link, allowing the material cylinder and cylinder cover to push the first link and the second link respectively. The safety switch is triggered by the combined action of the first link and the second link. This design is simple and efficient. Compared to existing technologies, it typically only requires adding one more link structure to ensure that the snow melting machine can only start normally when the material cylinder and cylinder cover are in place.

[0014] As a preferred embodiment, the safety switch is disposed on the first link or the second link, and the first link and the second link move toward each other under the push of the first push column and the second push column, respectively, to trigger the safety switch.

[0015] Furthermore, the safety switch is mounted on either the first or second connecting rod, which moves towards each other under the pushing action of the material cylinder and the cylinder cover, respectively. If the safety switch is mounted on the first connecting rod, the first pusher pushes the first connecting rod towards the second connecting rod. The safety switch cannot be triggered when the second connecting rod is not moving; it is only triggered when the second pusher pushes the second connecting rod further towards the first connecting rod. This design is simple, reliable, and ensures greater safety and reliability for the snow melting machine.

[0016] As a preferred embodiment, the linkage structure includes a linkage part and a socket disposed on the machine base, and a fixing post disposed on the cylinder head and inserted into the socket. The linkage part has a trigger position and a blocking part that normally blocks the socket. When the material cylinder is installed in place, the trigger position is pushed to displace the blocking part and misalign it with the socket. When the material cylinder is installed in place, the fixing post is inserted into the socket and triggers the safety switch.

[0017] The linkage part forms a blocking part that can block the insertion, so that when the material cylinder is not installed in place, the cylinder cover cannot be fixedly connected to the machine base through the insertion hole, and thus the safety switch cannot be triggered by the fixing column. This effectively ensures that the snow melting machine can be installed stably and reliably only when the material cylinder and cylinder cover are installed in place, and the safety switch can be triggered. The structure is stable and reliable.

[0018] As a preferred embodiment, the linkage is rotatably mounted on the machine base, and the material cylinder pushes the trigger position to rotate the blocking part so as to misalign with the corresponding insertion hole of the hand.

[0019] The linkage is rotatably mounted on the machine base. When the material cylinder is installed in place, the trigger position is pushed to rotate the blocking part, so that the blocking part can open the insertion hole and allow the cylinder cover to be installed normally. Preferably, the machine base can also be provided with an elastic structure to push the linkage to reset. In this way, when the material cylinder is removed, the linkage can quickly and automatically reset and block the insertion hole, so as to prevent the cylinder cover from being installed abnormally and better ensure the safety of the snow melting machine.

[0020] As a preferred embodiment, the linkage includes a linkage rod disposed within the machine base, the machine base having a trigger groove corresponding to the trigger position of the linkage rod, and the material cylinder having a protrusion extending into the trigger groove to push the trigger position.

[0021] A trigger groove is further provided on the machine base, and a protrusion that can extend into the trigger groove is provided on the material cylinder. When the material cylinder is installed in place, the protrusion extends into the trigger groove and triggers the trigger part, opening the insertion hole and facilitating the normal installation of the cylinder cover. The linkage rod is located within the machine base to further prevent accidental activation, thereby ensuring greater safety for the snow melting machine.

[0022] As a preferred embodiment, the safety switch includes a first safety switch and a second safety switch disposed within the machine base. The linkage structure includes a first triggering structure disposed in the material cylinder and capable of triggering the first safety switch, and a second triggering structure located in the cylinder cover and capable of triggering the second safety switch. When the first safety switch and the second safety switch are triggered simultaneously, the snow melting machine can start normally.

[0023] As a safer solution, the snow melting machine is equipped with a first safety switch and a second safety switch corresponding to the material cylinder and cylinder cover, respectively. This ensures that the snow melting machine can start normally only when the material cylinder and cylinder cover are installed in place simultaneously. The snow melting machine can also be configured to output different signals from the first safety switch and the second safety switch, so that when the user installs the material cylinder and cylinder cover separately, the snow melting machine can promptly determine whether the current installation is normal and provide corresponding feedback.

[0024] As a preferred embodiment, the base is provided with a first socket corresponding to the first safety switch and a second socket corresponding to the second safety switch, the material cylinder is provided with a first push post that extends into the first socket to trigger the first safety switch, and the cylinder cover is provided with a second push post that extends into the second socket to trigger the second safety switch.

[0025] Setting up a first insertion and a second insertion ensures that the first and second safety switches can be triggered when the material cylinder and cylinder cover are properly installed. On the other hand, a fixing structure can be set between the first push column and the first insertion hole, and between the second push column and the second insertion hole. This not only ensures the normal start-up of the snow melting machine, but also ensures the safe and reliable locking between the material cylinder and cylinder cover and the machine base.

[0033] To more clearly illustrate the overall concept of this application, a detailed description is provided below with reference to the accompanying drawings. It is understood that the specific embodiments described herein are merely illustrative of the relevant application and not intended to limit the application. Furthermore, it should be noted that, for ease of description, only the parts relevant to the application are shown in the accompanying drawings.

[0034] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present application will now be described in detail with reference to the accompanying drawings and embodiments. The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The singular forms “a,” “the,” and “the” used in this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0035] Existing general-purpose slush machines typically include a base and a material cylinder mounted on the base. The slush machine is usually equipped with a compressor, condenser, and evaporator connected by pipelines, as well as a stirring paddle and a drive motor that drives the stirring paddle. The evaporator and the stirring paddle are usually located inside the material cylinder. The compressor forces refrigerant to be transferred within the condenser and evaporator to cool the food placed in the material cylinder through the evaporator. The stirring paddle rotates under the drive motor, moving the beverage along with it, so that the beverage is cooled and processed evenly.

[0036] The snow melting machine described in this utility model is safe to use, such as Figures 1-5As shown, the snow melting machine includes a base 1, a refrigeration component and a power component disposed within the base 1, and a processing module disposed on the base 1. The refrigeration component includes a compressor and a condenser. The processing module includes a material cylinder 4, a stirring paddle 51, an evaporator 52, and a cylinder cover 6. The material cylinder 4 is mounted on the base 1 and forms a processing chamber with the base 1. The evaporator 52 is fixed to the base 1 and is in fluid communication with the compressor and the condenser to achieve refrigeration. The stirring paddle 51 is sleeved on the outside of the evaporator 52. The stirring paddle 51 and the evaporator 52 are both housed in the material cylinder 4. The evaporator 52 is used to cool and process the food placed in the material cylinder 4. The power component passes through the evaporator to drive the stirring paddle 51, so that the stirring paddle 51 drives the food to tumble, making the food processing more uniform.

[0037] To ensure users can conveniently and quickly add ingredients to the material tank 4, the top of the material tank 4 has an open upper opening 41. Normally, the upper opening 41 is large enough for users to completely add ingredients and easily reach into the material tank 4 to directly operate or clean the evaporator and stirring paddle. However, if the snow melting machine is started normally at this time, the evaporator 52 and stirring paddle 51 may injure the user. In this application, the processing module also includes a tank cover 6 located at the upper opening 41. When installed, the tank cover 6 completely covers the upper opening 41, preventing the user from directly touching the stirring paddle 51 and evaporator 52 during normal use of the snow melting machine.

[0038] To further enhance the safety of the snow melting machine, a safety switch and a linkage structure that triggers the safety switch are installed within the machine base. The snow melting machine is designed so that the safety switch can only be triggered by activating the linkage structure when the material cylinder and cylinder cover are properly and reliably installed. This means that if the user only installs the material cylinder or only the cylinder cover, the safety switch cannot be triggered, and the snow melting machine cannot be started normally. Compared to existing technologies that use smaller feeding channels for safety, this application's solution features an open top opening for the material cylinder, facilitating direct feeding by the user, particularly meeting the user's need to add special ingredients such as chunks of fruit to the material cylinder for processing various types of beverages. The safety switch and linkage structure further ensure that the snow melting machine can only be started normally when the processing module is securely and reliably installed. This avoids the safety risks associated with users starting the snow melting machine by mistakenly installing only one component, especially in existing solutions where the safety switch is triggered solely by the cylinder cover. The snow melting machine using the solution proposed in this application not only meets the processing needs of multi-functionality and ease of use, but also ensures safer and more reliable operation.

[0039] Specifically, as one embodiment of the safe and reliable snow melting machine described in the utility model, such as... Figures 1-4 As shown, the snow melting machine includes a base 1, a refrigeration component and a power component disposed within the base 1, and a processing module. Preferably, the base 1 includes a mounting platform 2 located at the upper section. The processing module includes a material cylinder 4, an evaporator 52, a stirring paddle 51, and a cylinder cover 6. The material cylinder 4 is detachably assembled at the mounting platform 2, the evaporator 52 is fixed to one side of the mounting platform 2, and the stirring paddle 51 is sleeved on the outer periphery of the evaporator 52. The material cylinder 4 is sealed to the side wall of the mounting platform 2, so that the material cylinder 4 and the mounting platform 2 enclose a processing cavity, and the evaporator 52 and the stirring paddle 51 are both located within the processing cavity of the material cylinder 4. The refrigeration assembly includes a compressor and a condenser in fluid communication with the evaporator 52. The compressor and condenser deliver refrigerant to the evaporator 52 to achieve cooling processing of the food. The power assembly includes a drive shaft 53 passing through the evaporator 52. Preferably, the drive shaft 53 is poweredly connected to the stirring paddle 51 at the front end of the evaporator 52, so that the power assembly drives the stirring paddle 51 to rotate and process within the material cylinder 4.

[0040] like Figure 3 As shown, the top of the material cylinder 4 has an open upper opening 41, which allows users to quickly add ingredients into the material cylinder 4. Users can also add special ingredients, such as fruit pieces, directly into the material cylinder 4. Furthermore, after use, the open design allows for easy cleaning of the evaporator 52 and stirring paddle 51 inside the material cylinder 4, and prevents the formation of hard-to-clean areas, ensuring safer and more hygienic storage of the snow melting machine. The rear side of the material cylinder 4 has a rear opening 42, through which the material cylinder 4 fits onto the stirring paddle 51 and evaporator 52, and abuts against the side wall of the mounting platform 2. The rear side of the material cylinder 4 also has a positioning ring rib 43, which abuts against the mounting platform 2 to fix the material cylinder 4, preventing poor stability during installation that could affect the normal operation of the snow melting machine. The material cylinder 4 is also provided with a first push column 44 on the rear side and a front buckle hole 45 on the front side of the material cylinder 4.

[0041] like Figure 4As shown, a cylinder cover 6 is provided at the upper opening 41 of the material cylinder 4. The cylinder cover 6 is fastened to the material cylinder 4 to cover it. In this way, during the use of the snow melting machine, the cylinder cover 6 can prevent the user from directly touching the evaporator 52 and the stirring paddle 51, avoiding safety risks. The front end of the cylinder cover 6 is provided with a handle 61, which can be fastened to the front fastening hole 45 to ensure that the cylinder cover 6 is reliably fastened to the material cylinder 4. The rear end of the cylinder cover 6 is provided with a second pushing post 62, a second locking post 63 and an upper positioning rib 64 that are fixedly engaged with the mounting platform 2.

[0042] like Figure 1 , Figure 2 As shown, the base 1 is equipped with a first safety switch 32 and a second safety switch 31. The first safety switch 32 and the second safety switch 31 are fixed to the inner side wall of the mounting platform 2. The side wall of the mounting platform 2 is provided with a first insertion hole 22 and a second insertion hole 21 corresponding to the first safety switch 32 and the second safety switch 31. The first safety switch 32 is provided with a first switch contact rod 321, and the second safety switch 31 is provided with a second switch contact rod 311. Preferably, the first switch contact rod 321 corresponds to the first insertion hole 22, and the second switch contact rod 311 corresponds to the second insertion hole 21. Preferably, a first insertion hole retaining rib 221 is also provided on the outer side of the first insertion hole 22. The base 1 is provided with a first mounting bracket 34 for fixing the first safety switch 32 and a second mounting bracket 33 for mounting the second safety switch 31. The first safety switch 32 and the second safety switch 31 are fixed to the inner side of the mounting platform 2 by the first mounting bracket 34 and the second mounting bracket 33, respectively. The side wall of the mounting platform 2 is also provided with a second locking hole 23 and a first locking pin 24.

[0043] In this invention, when the feed cylinder 4 is installed on the mounting platform 2, the rear opening 42 abuts against the outer periphery of the evaporator 52 and is sealed to the mounting platform 2. The positioning ring rib 43 abuts against and is fixed to the side wall of the mounting platform 2. Furthermore, the first pushing column 44 extends into the first insertion hole 22 to ensure that the first safety switch 32 can be triggered when the feed cylinder 4 is installed in place. Further, when the cylinder cover 6 is installed at the upper opening 41 of the feed cylinder 4, the upper positioning rib 64 abuts against and is positioned against the side wall of the mounting platform 2. Simultaneously, the second locking column 63 extends into the second locking hole 23 to ensure reliable locking between the cylinder cover 6 and the mounting platform 2, preventing the cylinder cover 6 from shifting during operation. At the same time, the second pushing column 62 extends into the second insertion hole 21 to push the second switch contact rod 311, thereby triggering the second safety switch 31.

[0044] In this embodiment, the first and second safety switches can only be triggered simultaneously when the material cylinder 4 and the cylinder cover 6 are both installed in place. Only then can the snow melting machine start normally. This avoids the safety risks to the user caused by the evaporator and stirring paddle not starting properly when the material cylinder or cylinder cover is only installed, thus improving the safety of the snow melting machine. This allows the snow melting machine to meet the needs of large-diameter feeding and facilitates cleaning of the material cylinder, evaporator, and stirring paddle through its large-diameter top opening, further ensuring safe operation. The first and second safety switches can be connected in series with the control device of the snow melting machine, so that the snow melting machine can only be triggered when both switches are simultaneously activated; alternatively, the first and second safety switches can be electrically connected to the control device separately, allowing the snow melting machine to not only start normally when both switches are activated simultaneously, but also to indicate to the user that the material cylinder or cylinder cover is not installed correctly.

[0045] It is understood that the mounting platform may not be provided with a first socket and a second socket for triggering the first safety switch and the second safety switch. The material cylinder and the cylinder cover may be separated by the housing of the mounting platform to trigger the first safety switch and the second safety switch through magnetic triggering or other means.

[0046] As a second embodiment of the safe snow melting machine described in this utility model, such as Figure 5 As shown, compared to Embodiment 1, this embodiment only sets a single safety switch. It should be noted that the specific Embodiment 1 and Embodiment 2 described respectively are not intended to mean that the two embodiments are completely independent of each other, but are merely used to specifically illustrate two preferred technical solutions, and the technical features and technical solutions of the two embodiments are common and can be used for mutual reference.

[0047] like Figure 5As shown, the linkage structure includes a safety switch 7, a first connecting rod 71, and a second connecting rod 72 disposed within the base 1. The safety switch 7 is fixed to the first connecting rod 71, and the first connecting rod 71 and the second connecting rod 72 can move towards each other. When the first connecting rod 71 and the second connecting rod 72 simultaneously move to a set position, the safety switch 7 disposed on the first connecting rod 71 can be triggered by the second connecting rod 72. Thus, the material cylinder is provided with a first pushing column capable of pushing the first connecting rod 71, and the cylinder cover is provided with a second pushing column capable of pushing the second connecting rod 72. When the material cylinder is fixedly installed with the base, the first pushing column extends into the base and pushes the first connecting rod 71 towards the position of the second connecting rod. Then, when the cylinder cover is installed in place, it pushes the second connecting rod 72 towards the first connecting rod, ultimately triggering the safety switch 7.

[0048] Compared to Embodiment 1, this embodiment may only require a single safety switch. The linkage structure includes a first trigger position and a second trigger position, for example, by providing a first link and a second link. Thus, the first trigger position is triggered when the material cylinder is installed in place, and the second trigger position is triggered when the cylinder cover is installed in place. This ensures that the safety switch can only be properly triggered when the material cylinder and cylinder cover are in place, guaranteeing the safe operation of the food processing machine.

[0049] Understandably, the safety switch can be fixed inside the base, and the safety switch can only be triggered when the first link and the second link push the safety switch simultaneously. Alternatively, the base may also be provided with a synchronizing link that is simultaneously pushed by the first link and the second link. The synchronizing link can push the safety switch, and the safety switch is only pushed by the synchronizing link when the first link and the second link are pushed simultaneously.

[0050] Understandably, the safety switch may be equipped with two contacts. The material cylinder may trigger the first contact, and the cylinder cover may trigger the second contact, thereby enabling the safety switch to conduct normally.

[0051] As a third embodiment of the safe snow melting machine described in this utility model, the linkage structure includes a linkage part disposed on the machine base. The cylinder cover can only be installed on the machine base and realize the conduction of the safety switch when the material cylinder is installed in place. It should be noted that the specific embodiments one, two, and three described are not intended to be completely independent of each other, but are merely for illustrating two preferred technical solutions. Furthermore, the technical features and solutions of the two embodiments are common and can be referenced from each other.

[0052] Specifically, the mounting platform of the machine base is provided with a first insertion hole trigger groove, and the linkage part includes a linkage rod disposed in the machine base. The linkage rod is rotatably disposed in the machine base. The trigger position of the linkage part includes a stop edge disposed in the linkage rod. The stop edge is located at the corresponding position of the trigger groove. When the material cylinder is installed in place, the push column disposed in the material cylinder is inserted into the trigger groove and pushes the linkage rod to rotate.

[0053] The base also has an insertion hole, and the linkage part has a blocking part that can block the insertion in a normal state. In this embodiment, the blocking part is a blocking rod extending to one side of the linkage rod. Preferably, the linkage rod is plate-shaped and rotatably fixed inside the base, and the side of the plate-shaped linkage rod extends outward to form the side guard and the blocking rod, respectively. Preferably, the linkage structure also includes a torsion spring that pushes the linkage rod to block the insertion hole in a normal state. When the material cylinder is installed in place, the pushing part presses the side guard, causing the linkage rod to rotate, thereby causing the blocking rod to be misaligned with the insertion hole. The cylinder cover can be fixed to the base through the insertion hole. Preferably, the base has a safety switch inside the insertion hole, so that the safety switch can be triggered normally when the cylinder cover is installed in place.

[0054] By implementing this embodiment, it can be ensured that the snow melting machine can only be started normally when the material cylinder and cylinder cover are in place, thereby ensuring the safety of the snow melting machine. Furthermore, the linkage structure is provided with a first trigger position and a second trigger position, which can be linked together. For example, the linkage rod can only open the socket and install the cylinder cover when the material cylinder is in place; it cannot be installed properly when only the cylinder cover is installed, and the safety switch cannot be triggered when only the material cylinder is installed, ensuring the safe operation of the snow melting machine.

[0055] Understandably, the linkage can move axially under the push of the material cylinder to open the insertion hole, so that the cylinder cover can be installed and fixed and the safety switch can be triggered.

[0056] In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0057] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if a device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures, but this does not imply that the actual device is inverted. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other orientations, rotated 90 degrees, or in other orientations, and the spatial relative descriptions used herein will be interpreted accordingly.

[0058] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special definition and therefore should not be construed as limiting the scope of protection of this application.

[0059] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or equivalent features without departing from the application's concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application will not be listed here.
