In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0052] Combine the following Figures 1 - 9 , the door body assembly and refrigeration equipment provided by the utility model embodiment are described in detail through specific embodiments and their application scenarios.

[0053] In the first aspect, Figure 1 , Figure 6 and Figure 7 As shown, the embodiment of the utility model provides a door assembly, which is applied to refrigeration equipment, including: a box door 1, a cabinet door 2, a sliding module 4 and a hanging structure 5;

[0054] The cabinet door 1 is rotatably arranged on the cabinet body 3 of the refrigeration equipment through at least two hinges 9, and the cabinet door 2 is arranged on the side of the cabinet door 1 away from the cabinet body 3; the sliding module 4 includes a slide rail 41 and a slide member 42; the slide rail 41 is arranged on the cabinet door 1 and extends along the width direction of the cabinet door 1; the slide member 42 is movably arranged on the slide rail 41;

[0055] The hanging structure 5 includes a clamping joint 51 and a clamping seat 52. The clamping joint 51 and the clamping seat 52 are respectively arranged on the sliding member 42 and the cabinet door 2. The clamping joint 51 and the clamping seat 52 are clamped and magnetically attracted.

[0056] Among them, the thickness of the cabinet door 1 is 18-60mm, for example, the thickness of the cabinet door 1 can be 18mm, 25mm, 35mm, 50mm, 55mm or 60mm; the thickness of the cabinet door 2 is 12-26mm, for example, the thickness of the cabinet door 2 can be 12mm, 15mm, 20mm or 26mm.

[0057] It is understandable that the door assembly is applied to refrigeration equipment such as refrigerators and freezers, and a hinge 9 is provided on the box body 3 of the refrigeration equipment, and the box door 1 is rotatably connected to the box body 3 through the hinge 9 to realize the opening or closing of the box door 1 relative to the box body 3. The outer side of the box door 1 is provided with a cabinet door 2, which can be a door panel, and the cabinet door 2 and the surrounding cabinets can be made of the same material to ensure that the appearance of the refrigeration equipment is consistent with the surrounding cabinets, so that the refrigeration equipment is better coordinated with the surrounding environment.

[0058] For the sliding module 4, the slide rail 41 can be a C-shaped guide rail, and the slider 42 can be a slide block. At least part of the slider 42 is movably arranged in the chute of the C-shaped guide rail along the extending direction of the C-shaped guide rail.

[0059] For the hanging structure 5, the clamping head 51 can be detachably installed on the slider 42 through locking parts such as bolts and rivets, or the clamping head 51 and the slider 42 can be integrally formed; correspondingly, the clamping seat 52 can be detachably installed on the cabinet door 2 through locking parts such as bolts and rivets. Of course, the clamping head 51 can also be arranged on the cabinet door 2, and correspondingly, the clamping seat 52 is arranged on the slider 42.

[0060] Meanwhile, the clamping seat 52 is provided with clamping structures such as a clamping opening and a clamping cavity, and the clamping head 51 is clamped in the clamping structure of the clamping seat 52; a magnetic attraction component is arranged between the clamping head 51 and the clamping seat 52, or at least part of the clamping head 51 and the clamping seat 52 are made of permanent magnets, so that when the clamping head 51 and the clamping seat 52 are clamped, the clamping head 51 and the clamping seat 52 are magnetically attracted to ensure a reliable connection between the clamping head 51 and the clamping seat 52.

[0061] As can be seen from the above, by arranging the sliding module 4 and the hanging structure 5 between the box door 1 and the cabinet door 2, the sliding module 4 includes a slide rail 41 and a slider 42 arranged in a sliding manner. When installing the cabinet door 2, the clamping head 51 and the clamping seat 52 of the hanging structure 5 can be respectively arranged on the slider 42 and the cabinet door 2 in advance, and then the slide rail 41 of the sliding module 4 is connected to the box door 1 to complete the installation of the sliding module 4. Then, the clamping head 51 and the clamping seat 52 are clamped, and the magnetic attraction between the clamping head 51 and the clamping seat 52 is utilized to ensure that the clamping head 51 and the clamping seat 52 are reliably connected into one body, so as to conveniently complete the installation of the cabinet door 2 and realize that the cabinet door can slide left and right relative to the box door along the width direction. This cabinet door installation method is convenient to operate, reduces the labor intensity of installers, and improves the installation efficiency of the cabinet door.

[0062] Furthermore, in practical applications, when the refrigeration equipment is installed in the cabinet in an embedded manner, during the process of opening or closing the box door 1, the cabinet door 2 can be moved relative to the box door 1 along the width direction to avoid the cabinet door touching the surrounding cabinets during the opening and closing process of the box door 1, which better meets the opening and closing requirements of the box door 1 of the refrigeration equipment.

[0063] In some embodiments, as Figure 2 、 Figure 3 and Figure 5 shown, the clamping head 51 is provided with a first magnetic part 501, and the clamping seat 52 is provided with a second magnetic part 502, and the first magnetic part 501 and the second magnetic part 502 are attracted to each other.

[0064] It is understandable that when the card connector 51 and the card socket 52 are connected, the first magnetic member 501 and the second magnetic member 502 approach each other, and the first magnetic member 501 and the second magnetic member 502 attract each other to prevent the card connector 51 from detaching from the card socket 52.

[0065] Optionally, both the first magnetic member 501 and the second magnetic member 502 are permanent magnets. For example, the permanent magnet is a neodymium iron boron magnet. This design facilitates magnetic adsorption between the card connector 51 and the card socket 52 compared to an electromagnet.

[0066] Wherein, one end of the first magnetic member 501 facing the second magnetic member 502 has a different magnetic pole from one end of the second magnetic member 502 facing the first magnetic member 501, so that the first magnetic member 501 and the second magnetic member 502 attract each other.

[0067] Optionally, when the magnetic attraction force between the first magnetic member 501 and the second magnetic member 502 meets the installation requirements of the cabinet door 2, one of the first magnetic member 501 and the second magnetic member 502 is a permanent magnet, and the other of the first magnetic member 501 and the second magnetic member 502 is a ferromagnetic member. This design does not require considering the polarity of the first magnetic member 501 and the second magnetic member 502 during installation, improving the installation convenience.

[0068] In some examples, the first magnetic member 501 can be a ferromagnetic member, and the second magnetic member 502 can be a permanent magnet.

[0069] In practical applications, when the card connector 51 is a ferrous member or a steel member and the card socket 52 is a plastic member, the entire card connector 51 can be used as a ferromagnetic member. At this time, there is no need to install the first magnetic member 501 on the card connector 51, and only the second magnetic member 502 needs to be installed on the card socket 52.

[0070] In some embodiments, as Figure 2 、 Figure 3 and Figure 5 shown, the card connector 51 has a tongue 510, the card socket 52 has a card slot 520, the tongue 510 is opposite to the card slot 520 along the thickness direction of the cabinet door 2, and can be connected to the card slot 520.

[0071] It is understandable that the card connector 51 can be provided on the side of the sliding member 42 facing the cabinet door 2, and the card socket 52 is correspondingly provided on the side of the cabinet door 2 facing the sliding member 42. When installing the cabinet door 2, only need to control the cabinet door 2 to move towards the box door 1 along the thickness direction, and the tongue 510 can be connected to the card slot 520 along the thickness direction.

[0072] Since the card connector 51 and the card socket 52 can achieve magnetic attraction, when the tongue 510 and the card slot 520 are engaged, the tongue 510 and the card slot 520 can be configured as an interference fit or can be configured to be engaged according to a set size, and no specific limitation is made thereto.

[0073] In some examples, such as Figure 5 and Figure 6 shown, the structures of the tongue 510 and the card slot 520 are adapted to each other and both extend along the width direction of the door 1 of the box. When the tongue 510 and the card slot 520 are engaged, the tongue 510 is vertically limited between the upper side wall and the lower side wall of the card slot 520.

[0074] Among them, the cross-sectional shape of the tongue 510 in the vertical plane can be an isosceles trapezoid, a rectangle, etc.

[0075] In some embodiments, such as Figure 5 shown, in order to facilitate the magnetic attraction between the card connector 51 and the card socket 52, the first magnetic member 501 is provided on the tongue 510, and the second magnetic member 502 is provided in the card slot 520.

[0076] Specifically, when the card connector 51 is provided on the side of the sliding member 42 facing the cabinet door 2, and the card socket 52 is provided on the side of the cabinet door 2 facing the sliding member 42, the tongue 510 extends along the thickness direction of the cabinet door 2, the first magnetic member 501 is provided at one end of the tongue 510 facing the cabinet door 2, the notch of the card slot 520 faces the door 1 of the box, and the second magnetic member 502 is provided on the bottom surface of the card slot 520.

[0077] In this way, when the tongue 510 is engaged in the card slot 520, the first magnetic member 501 and the second magnetic member 502 are close to or in contact with each other, and this design is beneficial to ensuring the reliability of the attraction between the first magnetic member 501 and the second magnetic member 502.

[0078] In some embodiments, such as Figure 5 and Figure 6 shown, the wall of the card slot 520 is provided with a guiding surface, and the guiding surface and the tongue 510 are in sliding fit to guide the tongue 510 into the card slot 520; the first magnetic member 501 and the second magnetic member 502 are used to drive the tongue 510 into the card slot 520.

[0079] It can be understood that the first magnetic member 501 can be provided on the tongue 510, and the second magnetic member 502 can be correspondingly provided in the card slot 520. Then, when the guiding surface guides the tongue 510 into the card slot 520, the first magnetic member 501 and the second magnetic member 502 approach each other, and the magnetic attraction between the first magnetic member 501 and the second magnetic member 502 gradually increases to drive the tongue 510 into the card slot 520.

[0080] Since the clamping groove 520 has a notch end and a bottom end of the groove, it can be set that the opening width of the clamping groove 520 gradually decreases from the notch end to the bottom end of the groove. This design can make the groove wall of the clamping groove 520 automatically form a guiding surface (bevel surface) inclined to the thickness direction of the cabinet door 2; since the clamping tongue 510 and the structure of the clamping groove 520 are adapted to each other, this design also facilitates controlling the clamping tongue 510 to be directly inserted into the clamping groove 520 along the thickness direction.

[0081] In some embodiments, such as Figure 3 and Figure 4 shown, the clamping seat 52 includes a clamping seat body 521 and a fixing ear 522. The clamping seat body 521 and the fixing ear 522 are connected. The clamping groove 520 is arranged on the clamping seat body 521, and the fixing ear 522 is connected to the cabinet door 2.

[0082] It can be understood that the fixing ear 522 is provided with mounting holes, and the fixing ear 522 can be fixed to the cabinet door 2 by a locking bolt or a locking screw passing through the mounting holes.

[0083] Furthermore, as Figure 4 shown, in order to ensure that the clamping seat 52 is reliably fixed to the cabinet door 2, the clamping seat 52 can be provided with a plurality of fixing ears 522, and the plurality of fixing ears 522 are arranged around the clamping seat body 521.

[0084] Optionally, the fixing ear 522 can be provided with at least two, and at least one fixing ear 522 is arranged on the upper side of the clamping seat body 521 along the height direction of the cabinet door 2.

[0085] For example, three fixing ears 522 are provided, one of the fixing ears 522 is arranged on the upper side of the clamping seat body 521 along the height direction of the cabinet door 2, and the other two fixing ears 522 are arranged on the left and right sides of the clamping seat body 521 along the width direction.

[0086] In some embodiments, in order to ensure that the cabinet door 2 is reliably installed on the box door 1, a plurality of clamping heads 51 are provided on the sliding member 42, and a plurality of clamping seats 52 are provided; the plurality of clamping heads 51 are arranged along the width direction and are arranged in one-to-one correspondence with the plurality of clamping seats 52. At the same time, when any set of the relatively arranged clamping heads 51 and clamping seats 52 are clamped, magnetic attraction can be achieved.

[0087] In some embodiments, such as Figure 2 shown, the sliding member 42 includes a ball bracket 421 and an adapter seat 422; the ball bracket 421 is movably arranged on the slide rail 41 along the width direction, the adapter seat 422 is connected to the ball bracket 421, the clamping head 51 is arranged on the adapter seat 422, and the clamping seat 52 is arranged on the cabinet door 2.

[0088] It is understandable that the slide rail 41 can be a C-shaped guide rail, and a rolling fit can be achieved between the ball bracket 421 and the slide rail 41 by using balls, so that the sliding member 42 can move smoothly relative to the slide rail 41 without abnormal noise during the movement.

[0089] Meanwhile, the adapter seat 422 and the ball bracket 421 can be connected by welding, and the adapter seat 422 and the clamping joint 51 can be set as an integral structure.

[0090] Further, along the extending direction of the slide rail 41, the extending length of the ball bracket 421 can be set to be greater than the extending direction of the adapter seat 422. This design can increase the contact area between the ball bracket 421 and the slide rail 41 and reduce the contact friction force between the ball bracket 421 and the slide rail 41, thereby ensuring the stability and reliability of the movement of the sliding member 42 relative to the slide rail 41.

[0091] In some embodiments, as Figure 1 shown, in order to ensure the stability and reliability of the movement of the cabinet door 2 relative to the box door 1, multiple sets of sliding modules 4 and hanging structures 5 are respectively provided and are arranged in a one-to-one correspondence. At least one set of sliding modules 4 is arranged between the upper end of the box door 1 and the upper end of the cabinet door 2, and at least one set of sliding modules 4 is arranged between the lower end of the box door 1 and the lower end of the cabinet door 2.

[0092] Specifically, four sets of sliding modules 4 are provided. Two of the sliding modules 4 are arranged along the width direction of the box door 1 and are arranged between the upper end of the box door 1 and the upper end of the cabinet door 2. The other two sets of sliding modules 4 are arranged along the width direction of the box door 1 and are arranged between the lower end of the box door 1 and the lower end of the cabinet door 2.

[0093] In some embodiments, as Figure 1 and Figure 7 shown, the box door 1 is provided with a groove 101, and the sliding module 4 is arranged in the groove 101; the door body assembly further includes a decorative member for covering the notch end of the groove 101.

[0094] It is understandable that when the cabinet door 2 is installed on the outer side of the box door 1, the sliding module 4 on the box door 1 is connected to the cabinet door 2 through the hanging structure 5. At this time, the decorative member is not installed at the notch end of the groove 101.

[0095] In some application scenarios, if the cabinet door 2 is no longer installed on the outer side of the box door 1, at this time the sliding module 4 is no longer used. By covering the notch end of the groove 101 with the decorative member, a hidden design of the sliding module 4 can be realized to ensure the aesthetic appearance of the box door 1.

[0096] In a second aspect, as Figure 7 、 Figure 8 and Figure 9As shown, an embodiment of the utility model further provides a refrigeration device, comprising: a box body 3 and a door assembly as described in any one of the above items, the box body 3 has a storage compartment, and the box door 1 is rotatably provided on the box body 3 to open or close the storage compartment.

[0097] It is understandable that the box body 3 can be provided with a plurality of storage compartments, which are arranged in sequence from top to bottom along the height direction of the box body 3, and the box body 3 is provided with a set of door body components for controlling the opening and closing state of each storage compartment. Among them, the box body 3 is provided with a hinge 9 on one side corresponding to each storage compartment, and the box body 3 can be rotatably connected with the box door 1 of the door body component corresponding to the storage compartment through the hinge 9.

[0098] For each set of door body assemblies, since the cabinet door 2 can move left and right relative to the box door 1 in the width direction, when the refrigeration equipment is fully embedded, during the process of opening the box door 1, the cabinet door 2 can be controlled to move relative to the box door 1 toward the side away from the hinge 9 to avoid the cabinet body around the refrigeration equipment; during the process of closing the box door 1, the cabinet door 2 can be controlled to move relative to the box door 1 toward the side close to the hinge 9 until the cabinet door 2 returns to its original position to ensure that the side of the box door 1 is flush with the side of the cabinet door 2.

[0099] Since the refrigeration equipment includes a door body assembly, the specific structure of the door body assembly refers to the above embodiment, and the refrigeration equipment shown in this embodiment includes all the technical solutions of the above embodiment. Therefore, it has at least all the beneficial effects achieved by all the technical solutions of the above embodiment, which will not be repeated here one by one.

[0100] In some embodiments, Figure 8 and Figure 9 As shown, the refrigeration device also includes: a sliding door mechanism 6, which is arranged on the cabinet body 3 or the cabinet door 1, and is transmission-connected to the cabinet door 2, and is used to drive the cabinet door 2 to move relative to the cabinet door 1 along the width direction during the opening and closing process of the cabinet door 1; the refrigeration device is configured to be arranged in the accommodating space between the first cabinet body 7 and the second cabinet body 8; during the opening or closing process of the cabinet door 1, the sliding door mechanism 6 is used to change the position of the cabinet door 2 on the cabinet door 1 so that the cabinet door 2 avoids the side wall of the first cabinet body 7 or the second cabinet body 8.

[0101] It is understandable that an opening is provided on the outside of the accommodation space between the first cabinet 7 and the second cabinet 8, and this design allows the cabinet 3 of the refrigeration equipment to be integrally embedded in the accommodation space. In the process of the cabinet door 1 passing through the opening to control the opening or closing of the accommodation space, the sliding door mechanism 6 is configured to drive the cabinet door 2 to move in the direction away from or close to the hinge 9 along the width direction. This design can ensure that the cabinet door 2 avoids the first cabinet 7 and the second cabinet 8, and avoids interference between the cabinet door 2 and the side walls of the first cabinet 7 and the second cabinet 8, thereby meeting the requirement that the cabinet door 1 can be opened and closed smoothly.

[0102] During the process of opening the cabinet door 1, the sliding door mechanism 6 drives the cabinet door 2 to move a preset distance in the width direction away from the hinge 9. In this way, the cabinet door 2 can smoothly avoid the side wall of the second cabinet body 8, so that the cabinet door 1 can be fully opened, facilitating users to access items.

[0103] Similarly, during the process of closing the cabinet door 1, the sliding door mechanism 6 drives the cabinet door 2 to move a preset distance in the width direction towards the side close to the hinge 9. When the cabinet door 1 is fully closed, the cabinet door 2 will return to its initial position. In this way, the cabinet door 2 can smoothly avoid the side wall of the first cabinet body 7, so that the cabinet door 1 can be fully closed, maintaining the overall aesthetics and sealing performance.

[0104] In this embodiment, the cabinet door 2 is movably arranged outside the cabinet door 1 in the width direction of the cabinet door 1, and the sliding door mechanism 6 is used to drive the cabinet door 2 to move relative to the cabinet door 1 during the opening or closing process of the cabinet door 1, so that the cabinet door 1 can avoid the first cabinet body 7 and the second cabinet body 8 on the side during the opening and closing processes, avoiding interference between the cabinet door 2 and the outside when the cabinet door 1 rotates, and meeting the usage requirements of users in different scenarios. This design not only improves the convenience of use but also can avoid possible damage to the door body assembly during use. At the same time, this design also enables the refrigeration equipment to better integrate into the home environment, achieving the effects of overall aesthetics and sealing.

[0105] In some embodiments, as Figure 9 shown, the sliding door mechanism 6 is connected to the sliding member 42 to drive the sliding member 42 to move along the slide rail 41.

[0106] It can be understood that during the opening and closing process of the cabinet door 1, the sliding door mechanism 6 drives the sliding member 42 to move relative to the slide rail 41 in the width direction. Since the sliding member 42 is connected to the cabinet door 2 through the hanging structure 5, the sliding door mechanism 6 is used to drive the cabinet door 2 to move relative to the cabinet door 1, ensuring that the cabinet door 2 does not interfere with the side cabinet body. This design realizes the integration of the sliding door mechanism 6 and the sliding module 4.

[0107] Among them, since there are multiple sliding modules 4, at least one of the multiple sliding modules 4 close to the hinge 9 can be integrally designed with the sliding door mechanism 6.

[0108] In some embodiments, as Figure 8 and Figure 9As shown, the door 1 of the box is rotatably connected to the box body 3 through a hinge 9, and the cabinet door 2 can move between a first position and a second position relative to the door 1 of the box in the width direction; when the cabinet door 2 is in the first position, the door 1 of the box closes the storage compartment, and the side of the cabinet door 2 facing the hinge 9 approaches the hinge 9; when the cabinet door 2 is in the second position, the door 1 of the box opens the storage compartment, and the side of the cabinet door 2 facing the hinge 9 moves away from the hinge 9, and the side of the cabinet door 2 and the side of the door 1 of the box are offset to avoid the side walls of the first cabinet body 7 or the second cabinet body 8.

[0109] It can be understood that the storage compartment is used to store items to be refrigerated or frozen. When the door 1 of the box closes the storage compartment, the door 1 of the box is in a closed state, and the side of the cabinet door 2 is at a first distance (close to zero) relative to the hinge 9 of the refrigeration device. For example, the side of the cabinet door 2 and the side of the door 1 of the box are flush. At this time, the cabinet door 2 can completely cover the door 1 of the box, ensuring that the cabinet door 2 of the accommodation space exposed by the refrigeration device is consistent with the surrounding first cabinet body 7 and the second cabinet body 8 in appearance.

[0110] When the door 1 of the box opens the storage compartment, the door 1 of the box is in an open state, and the side of the cabinet door 2 is at a second distance (the second distance is greater than the first distance) relative to the hinge 9 of the refrigeration device. For example, the side of the cabinet door 2 and the side of the door 1 of the box are offset, and a gap is formed that can accommodate the side of the first cabinet body 7 or the second cabinet body 8, so as to avoid collision or interference between the cabinet door 2 and the first cabinet body 7 or the second cabinet body 8 due to the opening of the door 1 of the box.

[0111] In some embodiments, as Figure 8 shown, the sliding door mechanism 6 includes: a trigger member and a linear driving member. The trigger member is used to obtain the opening and closing signal of the door 1 of the box; the linear driving member is arranged between the door 1 of the box and the cabinet door 2 and is connected to the trigger member; wherein, the linear driving member is used to drive the cabinet door 2 to move along the width direction of the door 1 of the box according to the opening and closing signal fed back by the trigger member.

[0112] It can be understood that in order to facilitate controlling the working state of the linear driving member according to the opening and closing signal fed back by the trigger member, the trigger member can be electrically connected to the control module, and the control module and the linear driving member are electrically connected.

[0113] The trigger member can be a photoelectric switch, and the photoelectric switch judges the opening and closing state of the door 1 of the box by detecting the distance change of the door 1 of the box relative to the box body 3. The trigger member can also be an angle sensor, which judges the opening and closing state of the door 1 of the box by detecting the angle change of the door 1 of the box relative to the box body 3;

[0114] The linear driving member can be a telescopic rod such as a cylinder or an electric push rod. The linear driving member extends along the width direction. The first end of the linear driving member is connected to the door 1 of the box, and the second end of the linear driving member is connected to the cabinet door 2 to realize driving the cabinet door 2 to move relative to the door 1 of the box in the width direction.

[0115] Wherein, when the door body assembly includes the above-mentioned sliding module 4 and the hanging structure 5, the linear driving member is arranged on the box door 1, the first end of the linear driving member is connected to the box door 1, and the second end of the linear driving member is connected to the sliding member 42 of the sliding module 4.

[0116] Taking the trigger as an angle sensor as an example, the control of the linear driving member on the cabinet door 2 during the opening and closing of the box door 1 will be specifically described as follows.

[0117] In practical applications, the angle sensor is installed on the hinge axis corresponding to the hinge 9 to monitor the rotation state of the box door 1 relative to the hinge axis. When the box door 1 is opened, the angle sensor feeds back an opening signal to the linear driving member, and the linear driving member drives the cabinet door 2 to move away from the hinge 9 along the width direction of the box door 1; when the box door 1 is closed, the angle sensor feeds back a closing signal to the linear driving member, and the linear driving member drives the cabinet door 2 to move towards the hinge 9 along the width direction of the box door 1.

[0118] Furthermore, as the opening or closing amplitude of the box door 1 is different, the angle sensor can also obtain the rotation angle of the box door 1. The linear driving member can determine the preset value of the movement according to the rotation angle. During the opening process of the box door 1, according to the rotation angle when the box door 1 is opened, the stroke of the telescopic end of the linear driving member is determined, and then the linear driving member drives the cabinet door 2 to move a preset distance away from the hinge 9 to avoid interference between the cabinet door 2 and the external cabinet body; correspondingly, during the closing process of the box door 1, according to the rotation angle when the box door 1 is closed, the stroke of the telescopic end of the linear driving member is determined, and then the linear driving member drives the cabinet door 2 to move a preset distance towards the hinge 9 to avoid interference between the cabinet door 2 and the external cabinet body, and finally the reset of the cabinet door 2 is realized.

[0119] Finally, it should be noted that the above embodiments are only used to illustrate the present invention, rather than to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention, and should all be covered by the scope of the claims of the present invention.
