Description

Technical Field

[0001] The present disclosure relates to the field of refrigeration technology, and in particular to a cabinet assembly and a freezer. Background Art

[0002] With the development of social economy and the improvement of people's living standards, refrigeration equipment (such as refrigerators, freezers, etc.) has become an indispensable household appliance in people's daily life. As a refrigeration equipment, the door of the freezer can let light in, which is convenient for people to observe the goods stored inside. It is widely used in commercial scenarios such as supermarkets, convenience stores, and shopping malls.

[0003] In the related art, most freezers are unable to identify the sales process of goods, making it difficult to understand whether the freezer is out of stock, resulting in untimely replenishment of the freezer and affecting sales. Utility Model Content

[0004] The present disclosure provides a cabinet assembly and a freezer, wherein the freezer can know whether there is a shortage of goods inside, so as to replenish the goods in time.

[0005] Specifically, the present disclosure is achieved through the following technical solutions:

[0006] According to a first aspect of an embodiment of the present disclosure, a cabinet assembly is provided, the cabinet assembly comprising a cabinet, a support frame, an elastic member and a first detection assembly. The cabinet is provided with a storage cavity and a mounting portion arranged in the storage cavity. The support frame is arranged in the storage cavity and is slidably connected to the mounting portion so that the support frame can be telescopically moved along the height direction of the cabinet. The elastic member is arranged between the support frame and the mounting portion so that the support frame can be reset to a zero-load state. The first detection assembly cooperates with the elastic member to generate a detection signal according to the elastic deformation of the elastic member or the displacement of the support frame.

[0007] The technical solution provided by the embodiments of the present disclosure includes at least the following beneficial effects:

[0008] When no goods are placed in the cabinet assembly, the support frame is in a zero-load state under the action of the elastic member, wherein the zero-load state includes an empty state. When goods are placed in the cabinet assembly, the gravity of the goods causes the support frame to move along the height direction of the cabinet, causing the elastic member to elastically deform and the support frame to displace. When the amount of goods on the support frame decreases, the elastic member will elastically deform and the support frame will displace under the action of the elastic member. The first detection component can generate a detection signal based on the elastic deformation of the elastic member or the displacement of the support frame, and the cabinet assembly can issue a replenishment reminder based on the detection signal, thereby promptly understanding whether the freezer is out of stock so that replenishment can be carried out in time.

[0009] The technical solution of the present disclosure is further described below:

[0010] In one embodiment, the first detection component includes a sliding rheostat fixedly mounted on the mounting portion, the sliding rheostat includes a conductive bracket, a resistor arranged on the conductive bracket, and a conductive sheet slidably connected to the conductive bracket, the conductive sheet is in electrical contact with the resistor and is fixedly connected to the support frame to support the support frame.

[0011] In one embodiment, the first detection component includes a sliding rheostat, which includes a conductive bracket, a resistor disposed on the conductive bracket, and a conductive sheet slidably connected to the conductive bracket. The conductive sheet is fixedly disposed on the mounting portion, and the conductive sheet is in electrical contact with the resistor. The conductive bracket is fixedly connected to the support frame.

[0012] In one embodiment, the first detection component includes a pressure sensor, which is disposed on at least one of the support frame and the mounting portion and is pressed against the elastic member to detect the magnitude of the resetting force of the elastic member.

[0013] In one embodiment, the first detection component includes a displacement sensor, which is disposed on the cabinet and used to detect the displacement of the support frame along the height direction of the cabinet.

[0014] In one embodiment, the cabinet assembly further includes a scanning device, and the scanning device is used to obtain information about the goods, wherein the information about the goods includes weight information of the goods.

[0015] In one embodiment, a plurality of partitions are arranged on the support frame at intervals along the width direction of the cabinet assembly to form a plurality of storage spaces for storing goods. The cabinet assembly further includes a plurality of second detection components corresponding to the storage spaces one by one, and the second detection components are used to detect whether there are goods in the storage spaces.

[0016] In one embodiment, the second detection component includes a transmitter and a receiver capable of receiving a signal sent by the transmitter, and the transmitter and the receiver are respectively arranged at two ends of the support frame.

[0017] According to a second aspect of the embodiments of the present disclosure, a freezer is also provided, comprising a control device, a cabinet door assembly, and a cabinet assembly in any of the above embodiments, wherein the cabinet door assembly is rotatably connected to the cabinet assembly to open or close the cabinet assembly. The control device is communicatively connected to the first detection assembly so that the control device determines whether to issue a replenishment reminder through a detection signal.

[0018] The technical solution provided by the embodiments of the present disclosure includes at least the following beneficial effects:

[0019] The cabinet door assembly is rotatably connected to the cabinet body assembly so that the user can open or close the cabinet body assembly through the cabinet door assembly. When goods are placed in the freezer, the weight of the goods causes the support frame to move along the height direction of the cabinet, causing the elastic member to elastically deform and the support frame to displace. When the goods on the support frame decrease, the elastic member will elastically deform and the support frame will displace under the action of the elastic member. The first detection component can generate a detection signal based on the elastic deformation of the elastic member or the displacement of the support frame. The control device of the freezer determines whether to issue a restocking reminder based on the detection signal, thereby promptly understanding whether the freezer is out of stock so that the freezer can be restocked in time.

[0020] In one embodiment, when the deformation amount of the elastic member is less than or equal to the preset deformation amount, the control device issues a replenishment reminder.

[0021] In one of the embodiments, when the displacement of the support frame is less than or equal to a preset displacement, the control device issues a replenishment reminder.

DETAILED DESCRIPTION

[0036] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numerals in different drawings represent the same or similar elements.

[0037] It should be understood that although the terms first, second, third, etc. may be used in the present disclosure to describe various information, such information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present disclosure, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information.

[0038] At present, the use of freezers is becoming more and more common, but there are many types and brands of freezers, which makes consumers have many choices. How to gain the favor of consumers and improve product competitiveness has become an issue that freezer manufacturers pay more and more attention to.

[0039] Freezers can lower the temperature inside the freezer through the refrigeration system and maintain a constant low temperature to inhibit bacterial growth and extend the shelf life of food, so they are used to preserve and freeze food and other items. Therefore, freezers have gradually become a necessity in people's lives. As a refrigeration device, freezers have doors that can let light in, making it easier for people to observe the goods stored inside. They are widely used in commercial scenarios such as supermarkets, convenience stores, and shopping malls.

[0040] In the related art, most freezers are unable to identify the sales process of goods, making it difficult to understand whether the freezer is out of stock, resulting in untimely replenishment of the freezer and affecting sales.

[0041] Based on this, the present disclosure provides a cabinet assembly 100, a refrigerator 1, and a replenishment reminder method for the refrigerator 1. The refrigerator 1 using the replenishment reminder method can understand whether the refrigerator 1 is out of stock, so as to replenish the stock in time.

[0042] like Figures 1 to 3 As shown, the present disclosure provides a freezer 1, including a cabinet device 10, a compressor 20, a condenser 30, an evaporator 40 and an expansion valve 50. The cabinet device 10 includes a cabinet assembly 100, a cabinet door assembly 200 and a refrigerating chamber 300 disposed in the cabinet assembly 100, and the cabinet door assembly 200 is rotatably connected to the cabinet assembly 100 to open or close the refrigerating chamber 300. The compressor 20, the condenser 30, the evaporator 40 and the expansion valve 50 are respectively disposed in the cabinet assembly 100.

[0043] The condenser 30 includes at least one of an air-cooled condenser 30 and a liquid-cooled condenser 30 .

[0044] Combination Figure 3 As shown, when the refrigerator 1 is in operation, the compressor 20 outputs a high-temperature and high-pressure gaseous refrigerant to the condenser 30, and the high-temperature and high-pressure gaseous refrigerant is condensed into a medium-temperature and high-pressure refrigerant through the condenser 30. The medium-temperature and high-pressure refrigerant is further reduced in pressure and temperature by the expansion throttling effect of the expansion valve 50, and the low-temperature and low-pressure liquid refrigerant flows out of the expansion valve 50 to the evaporator 40. The low-temperature and low-pressure liquid refrigerant evaporates into a gaseous refrigerant in the evaporator 40. The refrigerant absorbs a large amount of heat in the cold storage warehouse 300 during the evaporation process, thereby reducing the temperature in the cold storage warehouse 300, making it easier to use the cold storage warehouse 300 to refrigerate items and realize the refrigeration of the refrigerator 1. The refrigerant coming out of the evaporator 40 is replenished back to the compressor 20 to form a refrigerant circuit. In this way, the refrigerant circulates continuously in the refrigerant circuit to maintain the refrigerated environment of the cold storage warehouse 300.

[0045] like Figure 2 As shown, in some embodiments, the freezer 1 further includes a freezing chamber, and the freezing chamber is arranged below the refrigerating chamber 300 along the height direction of the freezer 1.

[0046] like Figure 2 As shown, the height direction of the refrigerator 1 is the Z-axis direction.

[0047] In some embodiments, the outer side walls of the refrigerating compartment 300 and the freezing compartment are covered with an insulation layer (not shown).

[0048] In some embodiments, the refrigerator 1 further includes an air-cooling heat dissipation assembly (not shown) disposed on the cabinet assembly 100 , and the air-cooling heat dissipation assembly can at least dissipate heat for the condenser 30 .

[0049] like Figure 4 As shown, in some embodiments, the cabinet assembly 100 includes a cabinet 110, a support frame 120, an elastic member 130 and a first detection assembly 140. The cabinet 110 is provided with a storage cavity 111 and a mounting portion 112 disposed in the storage cavity 111. The support frame 120 is disposed in the storage cavity 111 and is slidably connected to the mounting portion 112 so that the support frame 120 can be telescopically moved along the height direction of the cabinet 110. The elastic member 130 is disposed between the support frame 120 and the mounting portion 112 so that the support frame 120 can be reset to a zero-load state. The first detection assembly 140 cooperates with the elastic member 130 to generate a detection signal according to the elastic deformation of the elastic member 130 or the displacement of the support frame 120.

[0050] In this way, when the cabinet assembly 100 does not contain any goods, under the action of the elastic member 130, the support frame 120 is in a zero-load state, wherein the zero-load state includes an empty state. When the cabinet assembly 100 contains goods, the gravity of the goods causes the support frame 120 to move along the height direction of the cabinet 110, causing the elastic member 130 to elastically deform and the support frame 120 to be displaced. When the goods on the support frame 120 are reduced, the elastic member 130 will be elastically deformed and the support frame 120 will be displaced under the action of the elastic member 130. The first detection assembly 140 can generate a detection signal according to the elastic deformation of the elastic member 130 or the displacement of the support frame 120, and the cabinet assembly 100 can issue a replenishment reminder according to the detection signal, thereby timely understanding whether the freezer 1 is out of stock so that replenishment can be carried out in time.

[0051] It should be noted that if Figure 2 As shown, the height direction of the cabinet body 110 is the height direction of the refrigerator 1, that is, the Z-axis direction.

[0052] It should be noted that the elastic member 130 may be a spring, such as a coil spring. The elastic member 130 may be installed in a variety of ways, such as one end of the elastic member 130 may be installed on the support frame 120, and the other end may be installed on the installation portion 112 or the bottom wall of the storage cavity 111. As long as the installed elastic member 130 can restore the support frame 120 to a zero-load state, it will be sufficient.

[0053] like Figure 4 As shown, in some embodiments, the elastic member 130 includes a plurality of elastic members 130, and the plurality of elastic members 130 are disposed between the support frame 120 and the mounting portion 112. In this way, using a plurality of elastic members 130 to carry the support frame 120 can further ensure that the goods are placed on the support frame 120 stably and prevent the support frame 120 from tilting.

[0054] like Figure 4 As shown, in one example, the elastic members 130 include four, and the four elastic members 130 are respectively arranged at the four corners of the support frame 120. In this way, the four elastic members 130 are arranged at the four corners of the support frame 120 to support the support frame 120, which can further ensure the stability of the support frame 120 and prevent the support frame 120 from tilting when the goods are unevenly placed, thereby improving the stability of the goods placed on the support frame 120.

[0055] like Figure 4 As shown, in some embodiments, the first detection component 140 includes a sliding rheostat 141 fixed to the mounting portion 112, the sliding rheostat 141 includes a conductive bracket 1411, a resistor 1412 disposed on the conductive bracket 1411, and a conductive sheet 1413 slidably connected to the conductive bracket 1411, the conductive sheet 1413 is in electrical contact with the resistor 1412, and is fixedly connected to the support frame 120 to carry the support frame 120. In this way, the conductive sheet 1413 is in electrical contact with the resistor 1412 and is fixedly connected to the support frame 120. When the cargo on the support frame 120 is reduced, the support frame 120 will move under the action of the elastic member 130, and the support frame 120 drives the conductive sheet 1413 to move, so that the resistor 1412 connected to the sliding rheostat 141 changes, so that the voltage of the sliding rheostat 141 changes. The deformation of the elastic member 130 or the displacement of the support frame 120 can be obtained according to the change in voltage across the sliding rheostat 141, and the weight of the goods on the support frame 120 can be obtained. When the change in voltage across the sliding rheostat 141 reaches a preset change, the refrigerator 1 can issue a replenishment reminder to remind the merchant to replenish the goods, so that the merchant can timely understand whether the refrigerator 1 is out of stock, so as to replenish the goods in time.

[0056] Of course, in other embodiments, such as Figure 5As shown, the first detection component 140 may include a sliding rheostat 141, and the sliding rheostat 141 includes a conductive bracket 1411, a resistor 1412 disposed on the conductive bracket 1411, and a conductive sheet 1413 slidably connected to the conductive bracket 1411. The conductive sheet 1413 is fixedly disposed on the mounting portion 112, and the conductive sheet 1413 is in electrical contact with the resistor 1412. The conductive bracket 1411 is fixedly connected to the support frame 120. In this way, the conductive bracket 1411 is fixedly connected to the support frame 120. When the cargo on the support frame 120 is reduced, the support frame 120 will move under the action of the elastic member 130, and the support frame 120 drives the conductive bracket 1411 to move, so that the conductive bracket 1411 and the conductive sheet 1413 move relative to each other, so that the resistor 1412 connected to the sliding rheostat 141 changes, and then the voltage at both ends of the sliding rheostat 141 changes. The weight of the goods on the support frame 120 can be obtained according to the change in voltage across the sliding rheostat 141. When the change in voltage across the sliding rheostat 141 reaches a preset change, the refrigerator 1 can issue a replenishment reminder to remind the merchant to replenish the goods, so that the merchant can timely understand whether the refrigerator 1 is out of stock so as to replenish the goods in time.

[0057] It should be noted that the “preset change amount” can be set by the merchant based on actual conditions to meet actual replenishment needs.

[0058] like Figure 6 As shown, in some embodiments, the first detection component 140 includes a pressure sensor 142, which is disposed on at least one of the support frame 120 and the mounting portion 112, and is pressed against the elastic member 130 to detect the magnitude of the reset force of the elastic member 130. In this way, when the goods on the support frame 120 are reduced, the support frame 120 moves under the action of the elastic member 130, and the elastic member 130 is also deformed at this time, and the reset force of the elastic member 130 changes accordingly, and the magnitude of the reset force of the elastic member 130 is detected by the pressure sensor 142. When the goods on the support frame 120 are reduced, the deformation of the elastic member 130 is also reduced, so that the reset force of the elastic member 130 is also reduced. Therefore, when the reset force of the elastic member 130 is less than or equal to the preset reset force, the freezer 1 sends a replenishment reminder to the merchant.

[0059] like Figure 7As shown, in some embodiments, the first detection component 140 includes a displacement sensor 143, which is disposed on the cabinet 110, and the displacement sensor 143 is used to detect the displacement of the support frame 120 along the height direction of the cabinet 110. In this way, when the goods on the support frame 120 are reduced, the support frame 120 moves under the action of the elastic member 130, and the distance between the support frame 120 and the support frame 120 in the zero-load state will gradually decrease when the goods are reduced. Therefore, when the displacement of the support frame 120 along the height direction of the cabinet 110 is less than or equal to the preset displacement, the freezer 1 sends a replenishment reminder to the merchant.

[0060] It should be noted that the displacement refers to the distance between the current support frame 120 and the support frame 120 when it is in a zero-load state.

[0061] See you later Figure 1 as well as Figure 4 As shown, in some embodiments, the freezer 1 includes a control device 60, and the control device 60 is connected to the first detection component 140 for communication, so that the control device 60 determines whether to issue a replenishment reminder through a detection signal. In this way, when the goods on the support frame 120 are reduced, the elastic member 130 will be elastically deformed and the support frame 120 will be displaced under the action of the elastic member 130. The first detection component 140 can generate a detection signal according to the elastic deformation of the elastic member 130 or the displacement of the support frame 120 (for example, the voltage change at both ends of the sliding rheostat 141, the magnitude of the reset force fed back by the pressure sensor 142, and the magnitude of the displacement of the support frame 120 fed back by the displacement sensor 143), and the control device 60 of the freezer 1 determines whether to issue a replenishment reminder through the detection signal, thereby timely understanding whether the freezer 1 is out of stock, so that the freezer 1 can be replenished in time.

[0062] It should be noted that the control device 60 can control the overall operation of the refrigerator 1, such as operations associated with refrigeration, temperature display, lighting control, etc. The control device 60 includes control devices such as a programmable control device, a motion control card, and a microcomputer.

[0063] In some embodiments, the control device 60 may include one or more processors to execute instructions to complete the above-mentioned related control. The processor may be a micro-controller unit (MCU), a central processing unit (CPU) or a digital signal processor (DSP), etc.

[0064] In addition, the control device 60 may further include one or more modules to facilitate the interaction between the control device 60 and other components. For example, the control device 60 may include a multimedia module to facilitate the interaction between the user and the control device 60, such as a control panel.

[0065] In addition, the communication control means between the control device 60 and each actuator (such as the compressor 20) and the feedback element (such as the sliding rheostat 141, the pressure sensor 142, and the displacement sensor 143) belongs to the traditional technology and will not be repeated here.

[0066] The communication connection can be realized by wired communication technology or wireless communication technology, which is a conventional technology and will not be described in detail here. In addition, the communication connection between the above devices can be a direct communication connection or an indirect communication connection.

[0067] In some embodiments, the control device 60 is disposed on the cabinet assembly 100 .

[0068] In some embodiments, the control device 60 is disposed on the cabinet door assembly 200 and includes a control panel exposed from the cabinet door assembly 200 .

[0069] like Figure 5 As shown, in some embodiments, along the width direction of the cabinet assembly 100, a plurality of partitions 121 are arranged at intervals on the support frame 120 to form a plurality of storage spaces 122, and the storage spaces 122 are used to store goods. The cabinet assembly 100 also includes a plurality of second detection components 150 corresponding to the storage spaces 122, and the second detection components 150 are used to detect whether there are goods in the storage space 122. In this way, a plurality of partitions 121 are arranged at intervals on the support frame 120 to form a plurality of storage spaces 122, and the goods are stored in the storage space 122. Specifically, the same goods are placed in a storage space 122 to facilitate customers to purchase. By setting a second detection component 150 corresponding to the storage space 122 to detect whether there are goods in the storage space 122, after a certain kind of goods in a storage space 122 is sold out, the freezer 1 can send a replenishment reminder to the merchant.

[0070] It should be noted that the width direction of the cabinet assembly 100 is Figure 8 The X direction is shown.

[0071] It should be noted that there are many specific implementation methods for the second detection component 150, including infrared sensors, laser radars, etc.

[0072] It should be noted that there are many specific implementation methods for the partition 121 and the support frame 120 , and they can be manufactured in one piece or manufactured in parts and then assembled.

[0073] like Fig. 9 As shown, in some embodiments, the second detection component 150 includes a transmitter 151 and a receiver 152 capable of receiving a signal emitted by the transmitter 151. The transmitter 151 and the receiver 152 are respectively disposed at both ends of the support frame 120 and are located in the storage space 122. The goods are stored between the transmitter 151 and the receiver 152. In this way, the transmitter 151 and the receiver are respectively disposed at both ends of the support frame 120, and the goods are stored between the transmitter 151 and the receiver 152. Combined with the signal emitted by the transmitter 151 received by the receiver 152, the condition of the goods in the storage space 122 can be determined. When there are goods in the storage space 122, the goods will block the signal of the transmitter 151, so that the receiver 152 cannot receive the signal.

[0074] It can be understood that the transmitting device 151 can transmit a signal, such as an infrared signal, an ultrasonic signal, or a laser signal, etc. The receiving device 152 can receive the signal sent by the transmitting device 151, and the received signal can change depending on whether there are goods. When there are goods in the storage space 122, the receiving device 152 cannot receive the signal due to the obstruction of the goods.

[0075] See you later Figure 1 As shown, in some embodiments, the cabinet assembly 100 further includes a scanning device 160, and the scanning device 160 is used to obtain information about the goods. Among them, the information about the goods includes the weight information of the goods. In this way, the goods are scanned by the scanning device 160 to obtain the information about the goods. In particular, the weight information of the goods can be obtained. By using the correlation between the elastic deformation of the elastic member 130 or the displacement of the support frame 120 and the weight of the goods placed on the support frame 120, the relationship between the deformation and displacement and the weight of the goods on the support frame 120 can be obtained, so that the weight of the goods on the current support frame 120 can be obtained based on the deformation and displacement.

[0076] It should be noted that the information of the goods also includes the name of the goods, production date, shelf life, etc. When the merchant puts in the goods for the first time or replenishes the goods, the name, quantity, production date, shelf life, weight and other information of the goods are input by scanning the goods through the scanning device 160.

[0077] Furthermore, in one example, the correlation between the voltage across the sliding rheostat 141 and the weight of the goods is used to obtain the relationship between the voltage across the sliding rheostat 141 and the weight of the goods on the support frame 120, thereby obtaining the weight of the goods currently on the support frame 120 according to the voltage across the sliding rheostat 141. If the same kind of goods are placed on the support frame 120, the number of goods currently on the support frame 120 can be obtained by comparing the total weight with the weight of a single item.

[0078] In some embodiments, the refrigerator 1 further includes a human sensor (not shown), which is used to detect whether there is a person in front of the refrigerator 1. When it is detected that there is a person approaching the refrigerator 1, the refrigerator 1 displays the items in the refrigerator to facilitate the customer to buy.

[0079] The present disclosure also provides a replenishment reminder method for a refrigerator 1 , which is applied to the refrigerator 1 in any of the above embodiments.

[0080] In some embodiments, the replenishment reminder method of the refrigerator 1 includes: obtaining the deformation amount of the elastic member 130, and when the deformation amount of the elastic member 130 is less than or equal to the preset deformation amount, controlling the refrigerator 1 to issue a replenishment reminder. In this way, when the goods on the support frame 120 decrease, the elastic member 130 will undergo elastic deformation. When the deformation amount of the elastic member 130 is less than or equal to the preset deformation amount, it means that the goods on the support frame 120 may be out of stock, so the refrigerator 1 is controlled to issue a replenishment reminder to the merchant so that the refrigerator 1 can be replenished in time.

[0081] It should be noted that the deformation of the elastic member 130 can be obtained in a direct manner, for example, by directly measuring the deformation of the elastic member 130 through the displacement sensor 143. It can also be obtained in an indirect manner, for example, by obtaining the deformation of the elastic member 130 through the change of the restoring force of the elastic member 130. It is sufficient to be able to obtain the deformation of the elastic member 130, and no further details will be given here.

[0082] Of course, in other embodiments, the replenishment reminder method of the freezer 1 can also be: obtain the displacement of the support frame 120, and when the displacement of the support frame 120 is less than or equal to the preset displacement, control the freezer 1 to issue a replenishment reminder. In this way, when the goods on the support frame 120 decrease, the support frame 120 is displaced under the action of the elastic member 130. At this time, when the displacement of the support frame 120 is less than or equal to the preset displacement, it means that the goods on the support frame 120 may be out of stock, so the freezer 1 is controlled to issue a replenishment reminder to the merchant so that the freezer 1 can be replenished in time.

[0083] In some embodiments, the replenishment reminder method of the refrigerator 1 further includes: when the receiving device 152 receives the signal sent by the transmitting device 151, the refrigerator 1 is controlled to send a replenishment reminder. In this way, when there are goods in the storage space 122, the goods will block the signal of the transmitting device 151, so that the receiving device 152 cannot receive the signal, thereby confirming that there are goods in the storage space 122. When there are no goods in the storage space 122, due to the absence of the goods blocking, the receiving device 152 can receive the signal sent by the transmitting device 151, thereby confirming that there is no goods in the storage space 122.

[0084] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0085] The above embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the utility model concept of the present disclosure, and these all belong to the protection scope of the present disclosure.
