Description

Technical Field

[0001] The present application relates to the technical field of low-temperature storage equipment, and in particular to a refrigeration device. Background Art

[0002] A refrigerator is an electrical device that can maintain a constant low temperature. It can provide appropriate temperature and humidity conditions for fresh vegetables, fruits, meat and other ingredients, thereby improving the preservation effect of food.

[0003] Magnetic fields can inhibit the growth of microorganisms and molds, and to a certain extent, magnetic fields limit the free path of water molecules, thereby reducing the water loss rate in food. Therefore, installing a magnetic field preservation device in the refrigerator can better preserve the nutrition and taste of food and extend the shelf life of food.

[0004] Existing magnetic field preservation devices are generally set at the top or bottom of the drawer-type storage space in the refrigerator. Since the strength of the magnetic field decays with increasing distance, the above setting prevents the food in the storage space from being within the range of the highest magnetic field intensity, reducing the preservation effect of the magnetic field. Utility Model Content

[0005] In view of the above-mentioned deficiencies in the prior art, the purpose of the present application is to provide a refrigeration device, aiming to improve the preservation effect of a magnetic field preservation device in the storage space of the refrigeration device.

[0006] Another purpose of the present application may be to simplify the structure of the magnetic field preservation device.

[0007] Problems of the present application are not limited to the above-mentioned problems, and those skilled in the art can clearly understand other problems not mentioned from the following description.

[0008] In order to achieve the above objectives, this application adopts the following technical solutions:

[0009] On the one hand, the present application discloses a refrigeration device, which includes a box body, a fresh-keeping drawer assembly, a power supply and an electromagnetic generating assembly; a storage compartment is formed inside the box body; the fresh-keeping drawer assembly includes an outer frame body and a drawer body, the outer frame body is installed in the storage compartment, and the drawer body can be pulled out and arranged in the outer frame body to form a fresh-keeping storage space; the power supply is arranged on the outer frame body and is electrically connected to an external power supply; the electromagnetic generating assembly is arranged on the inner circumferential wall of the drawer body, and when the drawer body is pushed into the outer frame body, the electromagnetic generating assembly can be electrically connected to the power supply so that the electromagnetic generating assembly can apply a magnetic field to the fresh-keeping storage space, and there is a first distance between the electromagnetic generating assembly and the bottom of the drawer body, and the first distance is less than the height of the drawer body. In the above, when the drawer body is pushed into the outer frame, the electromagnetic generating component is electrically connected to the power supply, so that the electromagnetic generating component is energized, and a magnetic field is formed in the fresh-keeping storage space within the drawer body. The electromagnetic generating component is arranged on the inner circumferential wall of the drawer body and has the first distance from the bottom of the drawer body, so that the position with the maximum magnetic field intensity formed by the electromagnetic generating component is in the height direction of the drawer body, and the items placed in the drawer body have a certain height, so that the items stored in the drawer body can fall at the position with the maximum magnetic field intensity, thereby improving the fresh-keeping effect of the magnetic field on the items in the drawer body.

[0010] In some embodiments of the present application, the first distance is no less than one-third of the height of the drawer body, and / or the first distance is no more than one-half of the height of the drawer body. Generally, the height of stored items falls between one-third and one-half of the height of the drawer body. Therefore, arranging the electromagnetic generating assembly between one-third and one-half of the height of the drawer body can ensure the preservation effect of the electromagnetic generating assembly.

[0011] In some embodiments of the present application, the electromagnetic generating assembly includes an electrical connector and an electromagnetic coil; the electrical connector is provided on the drawer body and is arranged opposite to the power supply. When the drawer body is pushed into the outer frame, the electrical connector is electrically connected to the power supply, and when the drawer body is pulled out of the outer frame, the electrical connector is disconnected from the power supply; the electromagnetic coil is provided on the inner peripheral wall of the drawer body and is electrically connected to the electrical connector. When the drawer body is pushed into the outer frame, the electrical connector is in contact with the power supply, and the electromagnetic coil is energized, thereby generating a magnetic field in the drawer body; when the drawer body is pulled out of the outer frame, the electrical connector is disconnected from the power supply, the electromagnetic coil is de-energized, and the electromagnetic field in the drawer body disappears.

[0012] In some embodiments of the present application, the outer frame includes a top panel, a back panel, a first side panel, and a second side panel, wherein the first side panel and the second side panel are arranged at opposite ends of the back panel, and the top panel, the back panel, the first side panel, and the second side panel form a storage cavity for accommodating the drawer body, and the drawer body can be pushed into the storage cavity to close the storage cavity. The lower ends of the first side panel, the second side panel, and the back panel are fixed to the box body of the refrigeration device, so that an opening facing the direction in which the drawer body is pulled out is formed between the outer frame and the box body, and the drawer body is pushed into the storage cavity, and the drawer body can close the opening, thereby forming an independent fresh-keeping storage space in the drawer body.

[0013] In some embodiments of the present application, the power supply is disposed on the side of the back panel facing the accommodating cavity, and the electrical connector extends from the back of the drawer body toward the power supply. The electrical connector extends from the back of the drawer body, and the power supply is disposed on the side of the back panel facing the drawer body, thereby facilitating connection and disconnection between the power supply and the electrical connector and facilitating wiring of the power supply.

[0014] In some embodiments of the present application, the power supply is disposed on a side of the first side panel or the second side panel facing the accommodating cavity, and the electrical connector is disposed on a side wall of the drawer body opposite the first side panel or the second side panel, extending through the drawer body toward the power supply. The power supply and the electrical connector are connected to one side of the drawer body, and the contact length between the power supply and the electrical connector can be adjusted, thereby improving the connection stability between the power supply and the electrical connector.

[0015] In some embodiments of the present application, the electrical connector and the power supply are connected using contacts. Contact-connected connectors have a simple structure; the electrical connector and the power supply can be quickly connected and conducted when the drawer body is pushed into the outer frame, and can be quickly disconnected when the drawer body is pulled out of the outer frame.

[0016] In some embodiments of the present application, the electrical connector comprises one of a spring-loaded thimble connector and a spring-loaded contact connector. To minimize the storage space of the drawer body, the electrical connector utilizes a relatively simple structure. Both the spring-loaded thimble connector and the spring-loaded contact connector are simple in structure, easy to install, and offer high connection stability, ensuring the reliability of the electromagnetic generating assembly.

[0017] In some embodiments of the present application, the electromagnetic coil is configured as a square coil. The square coil is adapted to the shape of the drawer body, so that the electromagnetic coil is more evenly distributed in the drawer body, thereby making the magnetic field more evenly applied at various locations inside the drawer body.

[0018] In some embodiments of the present application, the electromagnetic coil is disposed parallel to the bottom of the drawer body. This arrangement allows the plane of maximum magnetic field strength generated by the electromagnetic coil to be parallel to the bottom of the drawer body, thereby improving the uniformity of the magnetic field preservation effect within the drawer body.

[0019] Beneficial effects:

[0020] According to at least one of the embodiments of the present application, the electromagnetic generating component is arranged on the inner wall of the drawer body, and there is a first distance between the electromagnetic generating component and the bottom of the drawer body, thereby improving the uniformity of the magnetic field distribution at the position where the items are placed in the drawer body, and enabling the items to be closer to the position with the maximum magnetic field intensity, thereby improving the preservation effect.

[0038] Specifically, the door 2 and the body 1 can be connected by a hinge, so that the door 2 of the refrigerator can rotate around the axis of the hinge to open and close the door 2 of the refrigerator, and then open and close the corresponding storage compartment 11.

[0039] In some embodiments of the present application, the door 2 can also be a sliding door structure. The door 2 is arranged on the front side of the box body 1 in a push-pull manner, that is, the door 2 can be used as a drawer door.

For example, a refrigerator compartment is suitable for storing vegetables, fruits, beverages, etc. The freezer compartment is suitable for storing meat, quick-frozen foods, etc.

[0042] In some embodiments of the present application, in order to meet more user needs, the storage compartment 11 may also include a variable temperature chamber, etc.

[0043] In some embodiments of the present application, multiple storage compartments 11 may be arranged in an upper and lower partition.

[0044] In some embodiments of the present application, multiple storage compartments 11 can be arranged in a left-right partition.

[0045] The storage compartment 11 may include a fresh-keeping drawer assembly 12. The fresh-keeping drawer assembly 12 may be disposed in a freezer compartment, a refrigerator compartment, or a temperature-controlled chamber.

[0046] A fresh-keeping drawer assembly 12 can be provided in the storage compartment 11. A plurality of fresh-keeping drawer assemblies 12 can be provided in the storage compartment 11.

[0047] In some embodiments of the present application, the box body 1 may be provided with a box liner 13. The box liner 13 is disposed within the box shell 15. The interior of the box liner 13 is hollow. Storage compartments 11 are formed within the box liner 13. A loading and unloading opening is formed on the front side of the box liner 13. Items can be placed into the corresponding storage compartment 11 through the loading and unloading opening. It is understood that multiple box liner 13 may be provided within the box body 1. Each box liner 13 may form one or more storage compartments 11.

[0048] In some embodiments of the present application, a shelf assembly 14 may be provided in the box 13 to form a shelf space for storing items.

[0049] The shelf assembly 14 can be detachably arranged in the box 13, so that the shelf assembly 14 can be removed from the box 13 for cleaning or changing the shelf space.

[0050] In some embodiments of the present application, the shelf assembly 14 may include shelves. The shelves are used to store items. The shelves may be configured as a single-piece plate structure. In other embodiments, the shelves may be configured as a plate structure that folds forward and backward or left and right. Alternatively, the shelves may be composed of a plurality of retractable or expandable shelf rods. By varying the distance between the shelf rods, different loading surfaces can be formed, and different shelf spaces can be created to accommodate different storage requirements for items.

[0051] In some embodiments of the present application, an installation space 16 is formed between the box shell 15 and the box liner 13. The installation space 16 can be used to form a thermal insulation layer. The thermal insulation layer can insulate the storage space inside the box body 1 from the outside.

[0052] In some embodiments of the present application, the refrigerator cools the storage compartment 11 through an air cooling system. That is, the refrigerator includes an air duct 51 and an air duct 51 assembly 5. The air duct 51 and the air duct assembly 5 are formed in the installation space 16.

[0053] The air duct assembly 5 may include an air duct 51 that is in communication with the inner chamber 13. A refrigeration system 53 (not shown) may be provided in the air duct 51. The cold energy generated by the refrigeration system 53 enters the inner chamber 13 through the air duct 51 to cool the food inside the inner chamber 13.

[0054] In some embodiments of the present application, the air duct 51 and the air duct assembly 5 may include a fan 52 (not shown in the figure). The fan 52 is arranged in the air duct 51 and can accelerate the air flow speed between the air duct assembly 5 and the box 13 throughout the air duct 51, thereby accelerating heat exchange and promoting cooling efficiency.

[0055] In some embodiments of the present application, the fresh food drawer assembly 12 may be provided with an air supply port 511 and an air return port 512. The air supply port 511 and the air return port 512 are respectively connected to the air duct 51. The fan 52 blows the cold air, which has been heated by the refrigeration system 53, into the fresh food drawer assembly 12 through the air supply port 511, and then returns the cold air to the air duct 51 and the air duct assembly 5 through the air return port 512.

[0056] Figure 2 This is a structural schematic diagram of the fresh-keeping drawer assembly provided in this application from the first perspective.

[0057] like Figure 2 As shown, in some embodiments of the present application, the fresh-keeping drawer assembly 12 includes an outer frame 121 and a drawer body 122. The outer frame 121 can be fixedly installed in the storage compartment 11. The drawer body 122 is retractably arranged in the outer frame 121 and forms a fresh-keeping storage space 1221 with the outer frame 121.

[0058] Figure 3 This is a schematic structural diagram of the outer frame provided in this application.

[0059] like Figure 2 and Figure 3 As shown, in some embodiments of the present application, the outer frame 121 may include a top plate 1211, a back plate 1212, a first side plate 1213, and a second side plate 1214. The first side plate 1213 and the second side plate 1214 are relatively arranged at both ends of the back plate 1212, and the bottoms of the back plate 1212, the first side plate 1213, and the second back plate 1212 are connected to the box 13. The top plate 1211, the back plate 1212, the first side plate 1213, and the second side plate 1214 form a storage space for accommodating the drawer body 122. The drawer body 122 can be pushed into the storage space to close the storage cavity, so that an independent fresh-keeping storage space 1221 is formed in the drawer body 122.

[0060] In some embodiments of the present application, guide rails may be provided on the inner sides of the first side panel 1213 and the second side panel 1214 of the outer frame 121, and connectors are provided on the side walls of the drawer body 122 opposite to the first side panel 1213 and the second side panel 1214, respectively. The connectors cooperate with the guide rails to enable the drawer body 122 to slide along the guide rails and be pulled out of or pushed into the outer frame 121. The coordinated use of the guide rails and the connectors can improve the movement stability of the drawer body 122.

[0061] Figure 4 This is a structural schematic diagram of the fresh-keeping drawer assembly provided in this application from a second perspective.

[0062] like Figure 4 As shown, in some embodiments of the present application, the refrigeration device may further include a power supply 3. The power supply 3 may be disposed on the outer frame 121. The power supply 3 may be electrically connected to an external power source. The power supply 3 may be configured as a power supply socket.

[0063] In another embodiment, the power supply 3 may also be provided on the box 13 . In this case, the device connected to the power supply 3 is configured to pass through the outer frame 121 to achieve electrical connection with the power supply 3 .

[0064] Figure 5 This is a schematic structural diagram of the drawer body provided in this application.

[0065] like Figure 5 As shown, in some embodiments of the present application, the refrigeration equipment may include an electromagnetic generating assembly 4. The electromagnetic generating assembly 4 may be arranged on the inner peripheral wall of the drawer body 122. When the drawer body 122 is pushed into the outer frame 121, the electromagnetic generating assembly 4 can be electrically connected to the power supply 3, so that the electromagnetic generating assembly 4 can apply a secondary magnetic field to the fresh-keeping storage space 1221, thereby improving the preservation effect of the items stored in the fresh-keeping storage space 1221. When the drawer body 122 is pulled out of the outer frame 121, the electromagnetic generating assembly 4 can be disconnected from the power supply 3. At this time, the electromagnetic generating assembly 4 is powered off, and the magnetic field in the fresh-keeping storage space 1221 disappears, which does not affect the taking and placing of items in the fresh-keeping drawer.

[0066] In the above description, the electromagnetic generating assembly 4 is arranged on the inner peripheral wall of the drawer body 122, which can improve the uniformity of the magnetic field distribution in the fresh-keeping storage space 1221 without affecting the storage of items.

[0067] In some embodiments of the present application, there is a first distance between the electromagnetic generating component 4 and the bottom of the drawer body 122. The first distance is less than the height of the drawer body 122. That is, the electromagnetic generating component 4 is arranged between the bottom and the top of the drawer body 122. The items stored in the fresh-keeping storage space 1221 generally have a certain height, and because the upper part of the drawer body 122 is limited by the outer frame 121, the storage height of the items is lower than the height of the drawer body 122. The magnetic field strength of the plane where the electromagnetic generating component 4 is installed in the drawer body 122 is higher, and the preservation effect on the items is better. Therefore, the electromagnetic generating component 4 is arranged between the bottom and the top of the drawer body 122. Compared with being arranged at the bottom or top of the drawer body 122, it can make the items in the fresh-keeping storage space 1221 closer to the position with greater magnetic field strength, thereby improving the preservation effect.

[0068] In some embodiments of the present application, the first distance may be no less than one-third of the height of the drawer body 122. That is, the electromagnetic generating assembly 4 is disposed at a position no less than one-third of the height of the drawer body 122. For example, the electromagnetic generating assembly 4 may be disposed at one-third, one-half, or two-thirds of the height of the drawer body 122.

[0069] In other embodiments, the first distance may be no greater than one-half of the height of the drawer body 122. For example, the electromagnetic generating assembly 4 may be disposed at one-fifth, one-quarter, one-third, or one-half of the height of the drawer body 122.

[0070] In other embodiments, the first distance may be no less than one-third of the height of the drawer body 122, and the first distance may be no more than one-half of the height of the drawer body 122. That is, the electromagnetic generating component 4 is arranged between one-third and one-half of the height of the drawer body 122. Since the strength of the magnetic field decays with increasing distance, the preservation effect of items that are farther away from the magnetic field is less ideal. If the electromagnetic generating component 4 is arranged at the bottom or top of the drawer body 122, the items stored in the fresh-keeping storage space 1221 are only in one direction where the magnetic field strength decays. The electromagnetic generating component 4 is arranged at the above-mentioned height, which can make the items in the drawer body 122 closer to the position with the highest magnetic field strength, thereby improving the preservation effect.

[0071] The electromagnetic generating assembly 4 can use a permanent magnetic component or an electromagnetic component. In some embodiments, a combination of an electromagnetic coil 42 and a permanent magnet can also be used to generate a magnetic field.

[0072] Based on the utilization rate of the fresh-keeping space and the adjustability of the magnetic field. In some embodiments, the electromagnetic generating assembly 4 may include an electrical connector 41 and an electromagnetic coil 42. The electrical connector 41 is electrically connected to the electromagnetic coil 42. The electrical connector 41 is arranged on the drawer body 122 and is arranged opposite to the power supply 3. When the drawer body 122 is pushed into the outer frame 121, the electrical connector 41 is electrically connected to the power supply 3 so that the electromagnetic coil 42 is energized to form a magnetic field in the fresh-keeping storage space 1221. When the drawer body 122 is pulled out of the outer frame 121, the electrical connector 41 is disconnected from the power supply 3, the electromagnetic coil 42 is not energized, and the magnetic field in the fresh-keeping storage space 1221 disappears. The electromagnetic coil 42 is arranged on the inner circumferential wall of the drawer body 122 to improve the uniformity of the magnetic field in the fresh-keeping storage space 1221.

[0073] In the above, the magnetic field is generated by connecting the electromagnetic coil 42 and the electrical connector 41 with the power supply 3, which has a simple structure, simplifies the structure of the electromagnetic generating component 4, and reduces product costs.

[0074] Figure 6 This is a schematic diagram of the distribution of electromagnetic intensity in the drawer body provided in this application. Figure 7 Schematic diagram of the magnetic induction line distribution of the electromagnetic coil provided in this application.

[0075] like Figure 6 and Figure 7 As shown, it can be seen that the magnetic field strength gradually decreases with increasing distance from the electromagnetic generating assembly 4. Using a 1000-turn electromagnetic coil 42 with a 1A current, and positioned at one-third the height of the drawer body 122, the magnetic field strength at the center of the electromagnetic coil 42 plane is approximately 4.3 mT, and the magnetic field strength at the center of the bottom of the drawer body 122 is approximately 3.1 mT. Therefore, positioning the electromagnetic generating assembly 4 between the top and bottom of the drawer body 122, particularly between one-third and one-half the height of the drawer body 122, can achieve a more uniform magnetic field distribution at the location where food is stored.

[0076] like Figure 4 As shown, in some embodiments of the present application, the power supply 3 is arranged on the side of the back plate 1212 facing the accommodating cavity, and the electrical connector 41 passes through the back of the drawer body 122 and extends toward the power supply 3. The electrical connector 41 passes through the back of the drawer body 122, and the power supply 3 is arranged on the side of the back plate 1212 facing the drawer body 122, which facilitates the connection and disconnection of the power supply 3 and the electrical connector 41, and the power supply 3 can be routed from the back of the box 1, which facilitates the wiring layout of the power supply 3.

[0077] In other embodiments, the power supply 3 is arranged on the side of the first side panel 1213 facing the accommodating cavity, and the electrical connector 41 is arranged on the side wall of the drawer body 122 opposite to the first side panel 1213 and extends through the drawer body 122 toward the power supply 3.

[0078] Alternatively, the power supply 3 is arranged on the side of the second side plate 1214 facing the accommodating cavity, and the electrical connector 41 is arranged on the side wall of the drawer body 122 opposite to the second side plate 1214 and extends through the drawer body 122 toward the power supply 3.

[0079] In the above, the power supply 3 and the electrical connector 41 are connected to one side of the drawer body 122, and the contact length between the power supply 3 and the electrical connector 41 can be adjusted as needed, thereby improving the connection stability between the power supply 3 and the electrical connector 41.

[0080] In some embodiments of the present application, the electrical connector 41 is connected to the power supply 3 using contacts. The contact-connected connector has a simple structure and a small size, and is suitable for use in scenarios where the installation space 16 between the drawer body 122 and the outer frame 121 is small. When the drawer body 122 is pushed into the outer frame 121, the contact-connected connector can quickly connect to the power supply 3, causing the electromagnetic coil 42 to generate a magnetic field; and when the drawer body 122 is pulled out of the outer frame 121, the contact-connected connector can quickly disconnect from the power supply 3 without affecting the pulling out of the drawer body 122.

[0081] In some embodiments of the present application, the electrical connector 41 may be a spring-type connector.

[0082] Spring-type thimble connectors are less susceptible to vibration and frequent plugging and unplugging, providing a reliable connection. They are suitable for use in situations where the fresh-keeping drawer assembly 12 frequently requires disconnection and reconnection. Furthermore, the material used for spring-type thimble connectors generally has excellent electrical conductivity, ensuring a stable electrical connection. Spring-type thimble connectors also take up less space, improving the space utilization of the fresh-keeping drawer assembly 12.

[0083] In some other embodiments of the present application, the electrical connector 41 may be a spring contact type connector.

[0084] The spring contact connector has excellent elasticity and contact stability, can adapt to frequent plugging and unplugging operations, and ensures connection reliability. In the embodiments of the present application, the use of the spring contact connector can further reduce the size of the connector, making it possible to achieve more compact circuit connections within a limited space. In addition, the spring contact connector has a simple structural design, which is easy to produce and maintain, while effectively reducing production costs. In the fresh-keeping drawer assembly 12, the use of this connector can improve overall durability and user experience.

[0085] It is understandable that in other embodiments, other types of electrical connectors 41 may also be used.

[0086] like Figure 5 As shown, in some embodiments of the present application, the electromagnetic coil 42 is arranged parallel to the bottom of the drawer body 122. Configuring the electromagnetic coil 42 parallel to the bottom of the drawer body 122 helps the magnetic field act evenly on the items in the drawer body 122, thereby enhancing the preservation effect of the magnetic field.

[0087] In some embodiments of the present application, an annular groove is formed on the inner wall of the drawer body 122, and the electromagnetic generating assembly 4 is embedded in the annular groove. The electromagnetic generating assembly 4 does not need to protrude from the annular groove, so as not to affect the storage of items in the drawer body 122.

[0088] In other embodiments of the present application, a limiting rib is formed on the inner wall of the drawer body 122, and the electromagnetic generating assembly 4 is fixed to the limiting rib, which is easy to disassemble and install. The limiting rib is provided on at least two opposite side walls of the drawer body 122. That is, the limiting rib can be provided on two opposite side walls of the drawer body 122. Alternatively, the limiting rib can be provided on three adjacent side walls of the drawer body 122. Alternatively, the limiting rib can be provided on the four side walls of the drawer body 122, in which case the limiting rib forms a ring-shaped structure.

[0089] In some embodiments, the electromagnetic coil 42 is configured as a square coil. The use of a square coil can make the distribution of the electromagnetic coil 42 in the drawer body 122 more uniform, so that the magnetic field acts more evenly at various positions in the fresh-keeping storage space 1221. The four corners of the square coil can better fit the corners of the drawer, ensuring that these areas can also obtain effective fresh-keeping effects. In addition, the square coil has a simple structure, is easy to produce and install, and is also conducive to heat dissipation, reducing the risk of overheating. In actual applications, the size of the coil can also be adjusted according to actual needs to adapt to drawer spaces of different sizes to ensure that the electromagnetic coil 42 is perfectly matched with the drawer body 122.

[0090] In some embodiments, the electromagnetic coil 42 is a coil with a cross-section of 260×290 mm. The magnetic field generated by the coil of this specification can meet the general preservation requirements of the fresh-keeping drawer assembly 12.

[0091] It is understood that the greater the number of turns of the electromagnetic coil 42, the greater the magnetic field strength. However, increasing the number of turns of the electromagnetic coil 42 increases the volume and weight of the coil, thereby affecting the installation stability of the electromagnetic coil 42 and the ease of movement of the drawer body 122. The smaller the coil radius, the greater the magnetic field strength. However, reducing the coil radius increases the coil resistance, which may affect the magnitude of the current.

[0092] In summary, the present application improves the uniformity of the magnetic field distribution in the fresh-keeping storage space 1221 by arranging an electromagnetic generating component 4 on the inner wall of the drawer body 122; the electromagnetic generating component 4 is arranged between one-third and one-half of the height of the drawer body 122, so that the food stored in the drawer body 122 can be closer to the position with the maximum magnetic field intensity, thereby improving the preservation effect of the food.

[0093] The magnetic field is generated by energizing the electromagnetic coil 42, which has a simple structure and reduces product costs.

[0094] The power supply 3 and the electrical connector 41 are in contact with each other, which has a simple structure, requires a small installation space 16, can be quickly connected or disconnected, and has stable and reliable contact.

[0095] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and application concept of this application, and these equivalent variations or substitutions are all included in the scope defined by the claims of this application.
