Description

Technical Field

[0001] The invention belongs to the technical field of gas stoves, and in particular relates to a connecting frame of a stove without a stove top, a stove without a stove top and an installation method thereof. Background Art

[0002] Cookers are indispensable kitchen appliances in daily family life. With the continuous improvement of people's living standards, the appearance of the kitchen has gradually received attention, and simple and elegant minimalist decoration has also been widely welcomed by people, which has led to the emergence of stoves without cooktops. The overall structure of the cooker is set under the countertop of the cabinet, and only openings for the burner and the control valve to pass through are opened on the countertop. Therefore, in terms of appearance, only two burners and a control valve can be seen on the countertop, making the overall appearance of the countertop simple and meeting the visual needs of users.

[0003] However, the stove without a cooktop has the defect of insufficient load-bearing capacity: the stove bottom shell that carries the stove burner and other parts is suspended under the table top. Specifically, the upper edge of the outer peripheral side wall of the stove bottom shell is provided with a flange extending horizontally outward, and the flange is connected to the table top through a connecting piece. Since the main parts of the stove are concentrated in the middle area of ​​the stove bottom shell, the center of gravity of the stove is far away from the connecting pieces, which not only increases the moment, but also increases the angle between the center of gravity and the connecting pieces and the vertical direction. As a result, the connecting pieces need to bear the vertical gravity while bearing the vertical gravity. The horizontal pulling force makes the connecting parts easily deformed in the horizontal direction, which may cause the connecting parts to separate from the countertop, or even cause the bottom shell of the stove to fall off as a whole, which not only affects the user's use, but also creates a safety hazard. In addition, the chassis of the bottom shell of the stove is not supported. After long-term use, the chassis surface is prone to deform downward, which may cause the stove head to shift in position, and in severe cases, the stove head may break, causing natural gas leakage, seriously endangering the user's life safety, and causing users to have concerns when purchasing stoves.

[0004] The applicant has improved the installation structure of a stove without a stovetop. The Chinese patent application number CN202323210764.7 discloses a stove without a stovetop, which includes a stove basin with an upward opening and suspended below the cabinet countertop, and the stove basin is provided with a horizontal bottom plate. A soaking plate is fixed on the lower surface of the countertop, and a connector with a protruding surface and extending downward is provided on the lower surface of the soaking plate, which is connected to the bottom plate of the stove basin, so that the stove basin is suspended and fixed below the countertop.

[0005] This patent specifically discloses two installation structures. Although these two installation structures solve the problem of preventing the stove basin from deforming and falling off, they are still relatively troublesome to install.

[0006] The first installation structure requires first fixing the connector to the soaking plate, then gluing the soaking plate to the bottom of the countertop, and then fixing the stove basin to the connector under the countertop. During the installation process, the stove basin needs to be lifted and fixed to the connector at the same time, which is not only time-consuming and prone to installation accidents, but also has high requirements for fixing the soaking plate.

[0007] The second installation structure firstly adheres the corresponding position of the soaking plate to the lower surface of the countertop; the second step is to further clamp and fix the soaking plate under the countertop by installing a control valve; the third step is to connect the fixing piece to the stove basin and place the stove basin under the countertop; the fourth step is to rotate the positioning piece above the countertop to connect it to the fixing piece. This installation method also requires that the positioning piece be rotated while lifting the stove basin to position and connect the fixing piece. Since the connection position between the two is under the countertop, positioning is more troublesome, and the installation process also requires more physical strength and time.

[0008] In view of this, the present invention is proposed. Summary of the invention

[0009] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art. The first purpose is to solve the cumbersome and complicated problems existing in the installation process of a stove without a cooktop, and to provide a connecting rack for a stove without a cooktop to simplify the installation steps and hang the bottom shell of the stove under the countertop at one time.

[0010] The second object of the present invention is to provide a connection frame for a stove without a cooktop, which structure shrinks the volume by rotating the second bracket close to the first bracket so that it can pass through the tabletop installation hole smoothly, and then rotates the second bracket in the opposite direction to open it and then support it on the tabletop.

[0011] The third object of the present invention is to provide a stove without a cooktop using the above-mentioned connecting frame.

[0012] A fourth object of the present invention is to provide a stove without a cooktop, which can reduce the distance between the connecting frame and the center of gravity of the stove bottom shell, thereby effectively preventing the stove bottom shell from falling off the tabletop due to load-bearing deformation.

[0013] A fifth object of the present invention is to provide a stove without a cooktop, which has the characteristics of adapting to countertops of different thicknesses and achieving stable fixation.

[0014] A sixth object of the present invention is to provide a method for installing a stove without a cooktop, so as to achieve the effect of hanging the bottom shell of the stove under the countertop at one time.

[0015] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0016] A connecting frame for a stove without a cooktop is used to hang a bottom shell of the stove under a tabletop. The connecting frame comprises:

[0017] A first bracket, used to connect with the bottom shell of the cooker;

[0018] The second bracket is hinged to the first bracket and has a support arm that can pass through the table top installation hole from below the table top and is used for supporting on the table top.

[0019] The present invention can hang the stove bottom shell carrying stove parts such as burners under the table top in a one-time and stable manner through the connecting frame. The first bracket of the connecting frame is mainly used to first firmly connect with the stove bottom shell to lay the foundation for the subsequent hanging operation; the second bracket of the connecting frame is connected to the first bracket in an articulated manner, and this connection method gives the second bracket a certain degree of freedom of movement. The support arm on the second bracket is used to smoothly pass through the table top installation hole from under the table top, thereby forming an effective support on the table top, thereby ensuring the stability and reliability of the entire stove connecting frame.

[0020] A further solution is that the second bracket has at least two states relative to the first bracket, including:

[0021] In the first state, the support arm of the second bracket is close to the first bracket and can extend into the mounting hole of the countertop from below the countertop;

[0022] In the second state, the support arm of the second bracket is away from the first bracket and is used to support the outer periphery of the tabletop mounting hole.

[0023] When the second bracket is in the first state, its support arm is close to the first bracket due to the rotation of the second bracket, and an appropriate distance is left between the outer periphery and the table mounting hole, allowing the support arm to smoothly extend into the table mounting hole from under the table, providing possibility for the subsequent installation action of the support arm passing through the table mounting hole.

[0024] In the second state, the support arm of the second bracket passes through the countertop mounting hole. Due to the inversion of the second bracket, it moves away from the first bracket and can just be supported on the peripheral area of ​​the countertop mounting hole. In this way, reliable support and stability are provided for the connecting frame of the entire stove without a cooktop, ensuring that the stove can remain stable during use without shaking, displacement or other adverse conditions.

[0025] A further solution is that the connecting frame includes an elastic member for providing an elastic force for the second bracket to switch from the first state to the second state;

[0026] Preferably, the elastic member is a torsion spring structure, and when the second bracket is in the first state, one end torsion arm of the torsion spring abuts against the side of the first bracket facing away from the second bracket, and the other end torsion arm abuts against the side of the second bracket close to the first bracket.

[0027] The above structure makes the process of switching the second bracket from the first state to the second state smoother and more convenient to a certain extent, and reduces problems such as jamming or wear that may be caused by switching of the rigid mechanical structure.

[0028] A further solution is that the second bracket includes a connecting arm, the connecting arm is connected to the supporting arm, an angle is formed between the connecting arm and the first bracket is pivotally connected, and the two cooperate to suspend the bottom shell of the cooker below the countertop after the supporting arm passes through the mounting hole;

[0029] Preferably, an angle α is formed between the connecting arm and the supporting arm, α is 70°-110°, more preferably α is 75°-105°, and even more preferably, α is 85°-95°;

[0030] Preferably, the connecting arm extends up and down, and the supporting arm is connected to the upper end of the connecting arm;

[0031] Preferably, an axial hole for mounting the pivot is provided at a certain distance from the upper end of the connecting arm, and the distance between the axial hole and the upper end of the connecting arm is smaller than the distance between the axial hole and the lower end of the connecting arm;

[0032] Preferably, the second bracket is a sheet metal part that is integrally bent to form a support arm and a connecting arm;

[0033] The two sides of the partial sheet metal parts forming the connecting arm are cut, bent, pressed and rolled into shaft holes, and an avoidance groove is punched on the connecting arm corresponding to the two shaft holes for avoiding the partial pivot located between the two shaft holes.

[0034] The second bracket of the present invention rotates relative to the first bracket so that the connecting arm can not only pass through the table mounting hole, but also rotate in the opposite direction to drive the supporting arm to be supported on the peripheral area of ​​the table mounting hole. The structural design of the second bracket is more reasonable and stable, which improves the overall connection performance and assembly effect.

[0035] The first bracket includes,

[0036] A fixed arm is provided at the lower end and is used for fixed connection with the bottom shell of the cooker;

[0037] A hinged arm, one end of which is connected to the fixed arm, and the other end of which is extended upward and hinged to the second bracket, and the second bracket rotates within a certain range around the hinged end of the hinged arm;

[0038] Preferably, an angle β is formed between the fixed arm and the articulated arm, β is 70°-110°, preferably β is 75°-105°, and more preferably, β is 85°-95°;

[0039] Preferably, the first bracket is a sheet metal part that is integrally bent to form a fixed arm and a hinged arm;

[0040] Preferably, the top end of the hinged arm is cut, bent, pressed and rolled to form an axis hole.

[0041] The first bracket of the present invention is hinged to the second bracket at the upper end of the hinged arm, so that the second bracket can rotate around the hinged end of the hinged arm within a specific range, thereby realizing the switching of different states of the second bracket to meet various requirements of installation and use.

[0042] In terms of structural optimization, a specific angle β is formed between the fixed arm and the articulated arm. The value range of the angle β is 75°-105°, and 85°-95° ​​is further preferred, and the most ideal situation is that β is 90°. This angle range can provide relatively balanced performance in terms of mechanical conduction, structural compactness, and reasonable spatial layout.

[0043] From the manufacturing process point of view, the first bracket uses a sheet metal part to bend in one piece to form a fixed arm and an articulated arm. This one-piece molding process helps to improve the overall structural strength and stability of the bracket. In addition, the top of the articulated arm is processed by cutting, bending, pressing and rolling to form an axial hole, which is used for articulation with the second bracket to ensure that the connection between the two is reliable and flexible in rotation, effectively improving the assembly accuracy and durability of the entire connecting frame.

[0044] The first bracket and the second bracket of the present invention are preferably formed by integrally bending a spring steel sheet metal part with elastic force. When the support arm of the second bracket extends into the table mounting hole, it utilizes its own elastic performance to produce a certain deformation, so that the support arm can pass through the table mounting hole more smoothly.

[0045] The invention provides a stove without a cooktop, comprising a stove bottom shell. The stove bottom shell is provided with an assembly part for installing the above-mentioned connecting frame.

[0046] A further solution is that the stove bottom shell is provided with at least two assembly parts;

[0047] Preferably, at least two assembly parts form a group and are distributed around the outer circumference of the same burner on the bottom shell of the cooker. Also preferably, at least two assembly parts around the outer circumference of the same burner are evenly distributed in the same circumferential direction.

[0048] Alternatively, the two assembly parts are mounted on one side of the two burners in a one-to-one correspondence and are substantially in the same straight line with the centers of the two burners.

[0049] Preferably, the assembly portion is arranged on a fixing frame, and the fixing frame is fixedly connected to the bottom shell of the cooker.

[0050] Further preferably, the furnace head and the corresponding assembly portion arranged on the outer side thereof are installed on the same fixing frame.

[0051] More preferably, the number of the fixing frames corresponds one to one with the number of the furnace heads.

[0052] A further solution is that the stove without a cooktop of the present invention includes a clamping assembly, which is arranged below the tabletop and cooperates with the support arm to clamp the tabletop between the support arm and the clamping assembly;

[0053] Preferably, the clamping assembly comprises,

[0054] An adjustable panel is arranged above the bottom shell of the cooker in an adjustable manner, and the adjustable panel is provided with an adjustable panel mounting hole for the support arm and the burner to pass through from bottom to top;

[0055] The adjusting component is connected with the adjustable panel, can adjust the distance between the adjustable panel and the supporting arm, and is used for clamping the table top between the supporting arm and the adjustable panel.

[0056] The present invention makes use of the characteristic that the adjustable panel in the clamping assembly can be adjusted up and down, so that, on the one hand, the stove without a cooktop can easily meet the installation requirements of various countertops with different thicknesses; on the other hand, it can also cooperate with the support arm to firmly clamp the countertop between the support arm and the clamping assembly, effectively solving the problem of the stove bottom shell falling off the countertop due to shaking, and greatly improving the stability and reliability of the stove without a cooktop after installation.

[0057] Further, the adjusting component includes,

[0058] a support frame connected to the adjustable panel;

[0059] The adjusting rod is used to install the support frame on the bottom shell of the stove, and the adjustable panel is driven to move up and down by adjusting the relative height between the support frame and the bottom shell of the stove;

[0060] Preferably, the support frame includes a side wall and a bottom wall, the side wall extends upward and is connected to the adjustable panel, the bottom wall is connected to the bottom shell of the stove through an adjusting rod, and the upper and lower distances between the bottom wall and the bottom shell of the stove are adjustable;

[0061] Preferably, the support frame is arranged outside the bottom shell of the stove, the side wall is located on the side of the bottom shell of the stove, the bottom wall is located below the bottom shell of the stove, and one end of the adjustment rod passes through the bottom wall and is connected to the bottom shell of the stove;

[0062] Preferably, the adjusting rod comprises a screw, which is threadedly connected to the supporting frame or the bottom shell of the stove, and the vertical distance between the supporting frame and the bottom shell of the stove is adjusted through screw transmission.

[0063] The present invention uses an adjustment rod to change the relative height between the support frame and the bottom shell of the cooker, thereby driving the adjustable panel to move up and down. This structural design enables the entire adjustment component to flexibly and accurately control the position of the adjustable panel to adapt to different installation requirements and usage scenarios.

[0064] The spiral transmission principle of the adjustment rod is further used to accurately adjust the upper and lower distances between the support frame and the bottom shell of the stove, thereby ensuring that the clamping assembly can stably and effectively perform its clamping function on the countertop, thereby improving the stability and reliability of the overall structure of the stove without a cooktop.

[0065] A further solution is that the stove without a cooktop of the present invention includes a knob installation assembly, and the knob installation assembly includes:

[0066] a knob mounting sleeve, at least partially adapted to be supported above a countertop;

[0067] The knob bracket is at least partially arranged under the countertop and fixedly connected to the bottom shell of the stove;

[0068] The knob mounting sleeve is detachably connected to the knob bracket;

[0069] Preferably, the height of the knob mounting sleeve relative to the knob bracket is adjustable;

[0070] Preferably, the position where the knob mounting sleeve is connected to the knob bracket is above the table top and / or in the knob mounting hole of the table top and / or below the table top;

[0071] Preferably, the knob mounting sleeve is threadedly connected to the knob bracket.

[0072] The present invention utilizes a knob installation assembly to further improve the stability of the stove bottom shell being fixedly installed under the countertop. By flexibly adjusting the upper and lower relative distances between the knob installation sleeve and the knob bracket, the assembly can be adapted to countertops of different thicknesses, thereby further improving the versatility and adaptability of the stove without a cooktop in a variety of installation environments.

[0073] The present invention also provides a method for installing a stove without a cooktop, comprising the following steps:

[0074] S1, connecting the first bracket of the connecting frame to the assembly part of the bottom shell of the stove;

[0075] S2, lift the bottom shell of the stove, rotate the second bracket of the connecting frame, so that the support arm passes through the table top installation hole from the bottom of the table top upward;

[0076] S3. Rotate the second bracket in the opposite direction, so that the support arm is supported on the periphery of the installation hole on the countertop, and the bottom shell of the cooker is suspended below the countertop.

[0077] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0078] The present invention can hang the stove bottom shell carrying stove parts such as the burner in a one-time and stable manner under the table through the connecting frame, which greatly simplifies the installation steps, improves the installation efficiency and convenience, and effectively reduces the manpower and time costs during the installation process.

[0079] The connecting frame adopts a hinged design and state switching between the second bracket and the first bracket: the support arm is close to the first bracket to extend into the countertop mounting hole, and is away from the first bracket to support the outer periphery of the countertop mounting hole, so that the installation of the stove bottom shell is stable and reliable, effectively solving the problem of falling off due to shaking, and ensuring safe use.

[0080] The cooktopless stove of the present invention adopts an adjustable panel whose height can be adjusted up and down, and can adapt to countertops of different thicknesses, effectively enhancing the applicability and compatibility of the stove in a variety of kitchen countertop environments, and can be widely applied to various kitchen decoration configuration requirements. There is no need for additional adjustment or adaptation operations due to differences in countertop thickness, reducing installation restrictions caused by differences in countertop thickness specifications, and greatly improving the practicality and convenience of the product.

[0081] In addition, the adjustment component of the clamping assembly drives the adjustable panel to move through the cooperation of the support frame and the adjustment rod. The structural design is reasonable and the adjustment process is relatively simple, which is conducive to quickly adjusting to the appropriate position to clamp the table top during installation, thereby improving installation efficiency.

[0082] In the knob installation assembly of the stove without a cooktop of the present invention, the diversity of the connection positions of the knob installation sleeve and the knob bracket and the adjustable distance between the two can adapt to different countertop thicknesses and knob models, improve the flexibility and versatility of the knob installation, and facilitate precise assembly in various product designs and usage demand scenarios.

[0083] The preferred threaded connection method between the knob mounting sleeve and the knob bracket can effectively prevent loosening or displacement caused by frequent rotation of the knob while ensuring a firm connection between the knob mounting sleeve and the knob bracket, thereby maintaining stability during knob operation and providing users with a continuous and reliable operating experience.

[0084] The method for installing a stove without a cooktop of the present invention comprises the following steps: firstly connecting a first bracket of a connecting frame to a bottom shell of the stove, and then simply lifting and rotating a second bracket of the connecting frame to complete the hanging installation of the bottom shell of the stove under the tabletop. The operation is simple, the installation difficulty is reduced, and it is convenient for installers to quickly master and implement.

[0097] It should be noted that these drawings and textual descriptions are not intended to limit the conceptual scope of the present invention in any way, but are intended to illustrate the concept of the present invention for those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0098] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0099] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0100] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0101] like Figure 1 and Figure 2 As shown, the connecting frame 1 of the stove without a cooktop of the present invention is used to hang the stove bottom shell 3 carrying many parts such as the burner head 2 under the table 4 at one time and firmly (see Fig. 9 and Fig.10 ), when implementing the operation process of hanging the stove bottom shell 3, the installer does not need to lift the stove bottom shell 3 and connect the connecting frame 1 to the stove bottom shell 3 at the same time, or does not need to lift the stove bottom shell 3 and connect the components of the connecting frame 1 at the same time, and other complicated and inconvenient actions. This feature greatly simplifies the installation process, improves the installation efficiency, and also reduces the potential safety hazards and installation quality problems caused by improper human operation, making the installation process of the stove without a cooktop more convenient, efficient and reliable.

[0102] The connecting frame 1 of the present invention is a complete integrated connecting structure, including a first bracket 11 and a second bracket 12. The first bracket 11 is used to connect to the stove bottom shell 3. The second bracket 12 includes a support arm 121. The support arm 121 is used to support the table top 4 from below the table top 4 through the table top mounting hole 41. The first bracket 11 and the second bracket 12 are hinged. The second bracket 12 can rotate within a predetermined angle range relative to the first bracket 11, so that the support arm 121 can pass through the table top mounting hole 41, and then through reverse rotation, it is stably supported on the table top 4 at the periphery of the table top mounting hole 41, thereby achieving the purpose of suspending the stove bottom shell 3 below the table top 4.

[0103] The second bracket 12 presents at least two different states relative to the first bracket 11: the first state is a first state, in which the support arm 121 of the second bracket 12 approaches the first bracket 11 due to the rotation of the second bracket 12 itself, thereby creating favorable conditions for the support arm 121 to smoothly penetrate into the countertop mounting hole 41 from under the countertop 4, and providing a practical possibility for the subsequent installation action of the support arm 121 to successfully pass through the countertop mounting hole 41; the second state is a second state, when the support arm 121 passes through the countertop mounting hole 41, the second bracket 12 rotates in the opposite direction, and the support arm 121 then moves away from the first bracket 11, and can just be stably supported on the countertop outside the countertop mounting hole 41. This ingenious design method provides a solid and reliable support force and stability guarantee for the connecting frame of the entire stove without a cooktop, effectively ensuring that the stove can always maintain a stable state during use, and preventing the occurrence of undesirable phenomena such as shaking or displacement.

[0104] In a further solution, the connecting frame 1 includes an elastic member 13, the main function of which is to provide the necessary elastic force for the second bracket to change from the first state to the second state.

[0105] In a preferred design, the elastic member 13 is a torsion spring structure. When the second bracket 12 is in the first state, the first torsion arm 131 of the torsion spring abuts against the side of the first bracket 11 facing away from the second bracket 12, while the second torsion arm 132 of the torsion spring abuts against the side of the second bracket 12 close to the first bracket 11.

[0106] The above design enables the torsion spring to assist the second bracket 12 in smoothly switching from the first state where the support arm 121 is close to the first bracket 11 and extends into the countertop mounting hole 41, based on its own elastic characteristics, to the second state where the support arm 121 is away from the first bracket 11 and supported on the countertop outer surface of the countertop mounting hole 41, thereby further optimizing the working performance of the connecting frame, improving the stability and reliability of the stove installation structure without a cooktop, and to a certain extent making the operation process smoother and more convenient, reducing problems such as jamming or wear that may be caused by switching of rigid mechanical structures.

[0107] In another embodiment, the connecting frame 1 of the present invention may also eliminate the design of the elastic member 13 , and the second bracket 12 can be manually controlled by the installer to rotate in the opposite direction relative to the first bracket 11 .

[0108] The first bracket 11 is provided with a fixed arm 111 at its lower end, and the fixed arm 111 is used to establish a stable fixed connection relationship with the stove bottom shell 3, and the fixed arm 111 is preferably adapted to the connection part of the stove bottom shell 3. The first bracket 11 also includes a hinged arm 112, one end of which is connected to the fixed arm 111, and the other end extends upward and is connected to the second bracket 12 in a hinged form, so that the second bracket 12 can be flexibly rotated around the hinged end of the hinged arm 112 within a certain angle range, thereby achieving switching between different states to meet various needs during installation and use.

[0109] Furthermore, an angle β is formed between the fixed arm 111 and the hinged arm 112, and the value range of this angle is between 70° and 110°, preferably between 75° and 105°, and further preferably between 85° and 95°. The design of this angle range relatively reduces the distance between the hinged end and the bottom shell of the stove, and cooperates with the spatial layout of the stove parts in the bottom shell of the stove, which can show relatively balanced and excellent performance in many aspects such as mechanical conduction path planning, overall structural compactness shaping, and reasonable spatial layout construction.

[0110] The first bracket 11 uses a sheet metal integral bending process to shape the fixed arm 111 and the articulated arm 112. This integral molding process has a significant role in promoting the overall structural strength and stability of the bracket. In addition, the top of the articulated arm 112 undergoes a series of fine processes such as cutting, bending, pressing and rolling to form an axial hole (not shown in the figure) for installing the pivot 14. The main purpose of this axial hole is to accurately articulate with the second bracket to ensure that the connection between the two has a high degree of reliability and rotation flexibility, thereby effectively improving the accuracy level of the entire connecting frame in the assembly process and the durability performance during use.

[0111] The structure of the second bracket 12 includes a connecting arm 122, which is connected to the support arm 121 and forms a specific angle therebetween, so that when the support arm 121 is supported on the countertop 4, the connecting arm 122 is downwardly inserted into the countertop mounting hole 41. The connecting arm 122 is connected to the first bracket 11 by a pivot connection, and the two cooperate with each other, and after the support arm 121 successfully passes through the countertop mounting hole 41, the cooker bottom shell 3 is stably suspended below the countertop 4.

[0112] An angle α is formed between the connecting arm 122 and the supporting arm 121, and the value range of the angle α is between 70° and 110°, preferably between 75° and 105°, and further preferably between 85° and 95°. The best design is that the angle α is less than 90°. When the second bracket 12 is in the second state, the supporting arm 121 is supported on the table 4, and the connecting arm 122 can abut against the hole wall of the table mounting hole 41 to enhance the lateral support effect.

[0113] The connecting arm 122 extends up and down, and the support arm 121 is connected to the upper end of the connecting arm 122 and is arranged on the side of the connecting arm 122 facing away from the first bracket. An axial hole 123 for installing the pivot 14 is provided at a certain distance from the upper end of the connecting arm 122, and the distance L1 between the axial hole 123 and the upper end of the connecting arm 122 is smaller than the distance L2 between the axial hole 123 and the lower end of the connecting arm 122.

[0114] The preferred solution is that the second bracket 12 is a sheet metal part formed by an integrated bending process to form a support arm 121 and a connecting arm 122, and the two sides of the sheet metal part forming the connecting arm 122 are respectively processed by cutting, bending, pressing and rolling to form an axis hole 123, and the two axis holes 123 are formed on both sides of the sheet metal part, and an avoidance groove 124 is stamped on the connecting arm 122 between the two axis holes 123, which is used to avoid the part of the pivot 14 located between the two axis holes (see Figure 2 ).

[0115] In order to increase the supporting strength of the support arm 121 and prevent it from deformation, one end of the support arm 121 away from the connecting arm 122 is turned upward to form a reinforcing rib 125; an anti-slip structure, such as an anti-slip pad or an anti-slip coating, is provided on the surface of one side of the support arm 121 used to support the table top to prevent the support arm from slipping on the table top and enhance the lateral stability.

[0116] The rotation design of the second bracket of the present invention relative to the first bracket is ingenious, so that the connecting arm can not only accurately pass through the table mounting hole, but also drive the support arm to be firmly supported on the peripheral area of ​​the table mounting hole during the reverse rotation. In this way, the structural design of the second bracket is significantly improved in rationality and stability, thereby effectively enhancing the overall connection performance and assembly effect. The avoidance groove design of the connecting arm makes the hinge structure of the second bracket and the first bracket more compact, further reducing the resistance caused by the excessive lateral size when the second bracket passes through the table mounting hole.

[0117] In a preferred embodiment, the first bracket 11 and the second bracket 12 of the present invention are preferably made of spring steel sheet metal with elastic properties, and are formed by an integrated bending process. In this way, when the support arm of the second bracket is extended into the tabletop mounting hole, it can produce a moderate deformation by virtue of its own elastic properties, thereby greatly facilitating the support arm to pass through the tabletop mounting hole more smoothly.

[0118] like Figure 3 and Figure 7As shown, the stove without a cooktop of the present invention comprises a stove bottom shell 3. The structure of the stove bottom shell 3 generally comprises a chassis 31 for carrying the burner 2 and other parts and a peripheral wall 32 extending upward from the four sides of the chassis 31. The chassis 31 is processed with concave and convex shapes to enhance its strength. The peripheral wall 32 is provided with a ventilation structure. The ventilation structure is generally designed as a ventilation hole 33 or the peripheral wall is designed in sections, and ventilation is performed using the gap between the two sections. The stove bottom shell 3 has an assembly part 30. The main function of the assembly part 30 is to install the above-mentioned connecting frame 1. The structure and connection method of the assembly part 30 are not limited. If screws are used for fixing, the assembly part 30 can be a screw hole on the stove bottom shell. In this way, the fixing arm 111 of the first bracket 11 is provided with a screw installation hole 113 (see Figure 1 ); if plug-in is adopted, the assembly part can be a socket on the bottom shell of the stove. There are many connection methods, which are not listed here one by one. Preferably, the connecting frame 1 and the bottom shell 3 of the stove are fastened and connected by screws, and the assembly part 30 is a screw hole. In addition, the assembly part 30 can be directly or indirectly provided on the bottom shell of the stove, that is, the assembly part can be directly provided on the bottom shell of the stove, and can also be installed on the bottom shell of the stove through an adapter, which will be described in detail later.

[0119] In order to reduce the number of holes punched on the table 4, the table mounting hole 41 is the burner mounting hole of the stove, and of course it can also be the knob mounting hole 42 of the table, preferably the burner mounting hole. Of course, it can also be another perforation set on the table, and a decorative cover needs to be installed to cover the support arm 121 supported on the table. Similarly, for the burner mounting hole, it is necessary to use a burner decorative cover or a liquid tray 5 to cover the support arm 121 (see Fig.10 and 11 ).

[0120] A further design scheme for the assembly part 30 is the number and position of the assembly part 30 on the stove bottom shell 3. The number of the assembly parts 30 is related to the size, weight, shape and number of burners 2 of the stove bottom shell 3. In order to obtain a stable installation effect, the stove bottom shell 3 is provided with at least two assembly parts 30. In a highly advantageous layout mode, at least two assembly parts 30 are combined into a group and reasonably distributed around the periphery of a specific burner 2 on the stove bottom shell 3, especially a single burner stove or a multi-burner design with a burner in the center. Of course, for a stove with multiple burners, an assembly part can be arranged around each burner, or an assembly part can be arranged around two burners that play a balancing role on the stove. More ingeniously, these assembly parts around the periphery of the same burner are evenly distributed in the same circumferential direction. The preferred solution of the present invention is to arrange two assembly parts 30 around each burner 2, and the assembly parts 30 are distributed on both sides of the burner 2 in a symmetrical manner. This evenly distributed design is not accidental. It can achieve an ideal balanced force effect in the mechanical structure, effectively avoiding structural stability problems that may be caused by local uneven force. At the same time, it also achieves an optimized configuration in terms of spatial layout, making the entire internal structure of the stove more compact and reasonable.

[0121] Another feasible assembly part layout scheme (not shown in the figure) is that, under the premise that the connecting frame can meet the predetermined strength, for multi-burner stoves, in order to save costs, the number of connecting frames can be reduced, and the stove only needs to have an assembly part on one side of the two burners, the assembly part corresponds to the burners one by one, and the two assembly parts and the centers of the two burners are roughly on the same straight line, that is, the two assembly parts are between the two burners or outside the two burners; but it should be noted that in order to meet the lateral stability of the stove, it is necessary to have a rigid installation requirement for the installation angle of the connecting frame, especially the extension direction of the support arm, and the extension directions of the support arms of the two connecting frames are opposite to each other, that is, if the two assembly parts are set between the two burners, the extension directions of the support arms are set relative to each other, and if the two assembly parts are set outside the two burners, the extension directions of the support arms are set opposite to each other. This layout method shows unique adaptability and practicality under some specific stove design concepts and kitchen space planning requirements, and can further optimize the overall space occupancy and operational convenience of the stove on the basis of meeting basic installation requirements.

[0122] In terms of the specific structure and installation form of the assembly part 30, it is preferred that the assembly part 30 is arranged on a fixing frame 34, and the fixing frame 34 and the stove bottom shell 3 are fixedly connected to ensure that a high degree of stability and reliability can be maintained under various use environments and working conditions. Further optimization design shows that the burner 2 and the corresponding assembly part 30 arranged on the outside thereof are installed together on the same fixing frame 34. This integrated installation strategy significantly improves the compactness and coordination of the structure, makes the connection between the components tighter and the cooperation more tacit, and effectively reduces the potential risks such as structural looseness or unstable connection caused by the scattered installation of components. More preferably, the number of fixing frames 34 and the number of burners 2 present a one-to-one precise relationship, and each fixing frame 34 is firmly supported on the chassis 31 of the stove bottom shell, thereby constructing a stable and orderly internal support frame, and at the same time, enhancing the strength of the stove bottom shell, ensuring the balanced distribution of the weight of the stove bottom shell, and providing a solid structural guarantee for the long-term stable operation of the entire stove.

[0123] A further solution is, Figure 4 , Figure 5 and Figure 7 As shown, the stove without a cooktop of the present invention includes a clamping assembly 6, which is arranged below the table top 4. The clamping assembly 6 is designed to closely cooperate with the support arm 121 in the connecting frame 1 to clamp the table top 4 between the support arm 121 and the clamping assembly 6, thereby improving the stability of the stove bottom shell 3 suspended below the table top.

[0124] The clamping assembly 6 mainly includes the following components:

[0125] The adjustable panel 61 has the unique property of being adjustable up and down on the top of the stove bottom shell 3, and is provided with an adjustable panel mounting hole 611 for the support arm 121 and the burner head 2 to pass smoothly from bottom to top. This design structure enables the adjustable panel 61 to flexibly adjust its height position according to different installation requirements and usage scenarios, thereby adapting to the installation requirements of various countertops of different thicknesses, greatly broadening the application range and adaptability of stoves without a stovetop.

[0126] The adjusting component 62 is connected to the adjustable panel 61 and is used to adjust the distance between the adjustable panel 61 and the supporting arm 121 , so as to clamp the tabletop 4 between the supporting arm 121 and the adjustable panel 61 .

[0127] The present invention cleverly uses the key feature that the adjustable panel in the clamping assembly can be adjusted up and down to significantly improve the performance of the stove without a cooktop from two core dimensions. First, when faced with a wide variety of countertops with different thicknesses on the market, the stove without a cooktop can easily achieve adaptive installation with the feature of the adjustable panel. Whether it is an ultra-thin countertop or an ultra-thick countertop, the stove and the countertop can be perfectly combined through simple adjustment operations, which greatly improves the versatility and adaptability of the product in different kitchen environments and effectively reduces the installation restrictions and inconvenience caused by the difference in countertop thickness. Second, through the close coordination mechanism with the support arm, the countertop can be firmly clamped between the support arm and the clamping assembly to form a stable overall structure. This stable clamping structure fundamentally and effectively solves the potential risk of the bottom shell of the stove falling off the countertop due to the possible shaking. During daily use, whether it is slight vibrations during cooking or accidental collisions in the kitchen environment, it will not easily destroy the stability of the connection between the stove and the countertop, thereby greatly improving the overall stability and reliability indicators of the cooktopless stove after installation, providing users with a safer, more durable and worry-free use experience.

[0128] A further solution is, Figure 5 As shown, the adjustment component 62 mainly includes:

[0129] The support frame 621 is connected to the adjustable panel 61; preferably, both of them have pin holes 620 and 610, and are fixedly connected by pins at the installation site, or the support frame and the adjustable panel are fixedly connected by other assembly methods such as screws. The support frame 621 extends along one side of the stove bottom shell 3. Preferably, there are two support frames 621, which are correspondingly arranged on the left and right sides of the stove bottom shell 3;

[0130] The adjusting rod 622 is used to install the supporting frame 621 on the stove bottom shell 3, and drive the adjustable panel 61 to move up and down by adjusting the relative height between the supporting frame 621 and the bottom plate 31 of the stove bottom shell.

[0131] The support frame 621 includes a side wall 6211 and a bottom wall 6212. The side wall 6211 extends upward and is connected to the adjustable panel 61, and the bottom wall 6212 establishes an adjustable connection relationship with the bottom plate 31 of the stove bottom shell 3 through the adjustment rod 622, and the upper and lower distances between the bottom wall 6212 and the bottom plate 31 of the stove bottom shell are flexible and adjustable. Preferably, the support frame 621 is an integrated structural member formed by bending a sheet metal part to form the side wall 6211 and the bottom wall 6212, so as to improve its supporting strength.

[0132] In order to ensure the convenience and stability of the connection between the adjustable panel 61 and the support frame 621, a downwardly protruding connection portion 612 is provided on the lower surface of the adjustable panel 61. The connection portion 612 is preferably an integral structural member formed by bending downward at both ends of the adjustable panel 61. The integrally formed design of the connection portion not only reduces the number of parts and reduces the complexity of assembly, but also enhances the strength and stability of the connection part, effectively avoiding the potential safety hazards and performance degradation problems caused by loose connection or separation of parts.

[0133] Considering the space utilization and packaging convenience of the adjustable panel 61 and the support frame 621 during transportation, the adjustable panel 61 and the support frame 621 are designed as two independent modules. At the installation site, the two can be easily assembled, usually using pins or bolts as the connection means, and the pin holes 610, 620 or bolt installation holes are correspondingly arranged on the connecting portion 612 of the adjustable panel and the side wall 6211 of the support frame.

[0134] The ventilation design is of vital importance in ensuring the combustion efficiency of the stove. In order to avoid affecting the ventilation effect inside and outside the stove, a vent 6120 is designed on the connection part 612 of the adjustable panel 61, and / or a vent 6210 is designed on the side wall 6211 of the support frame 621, which is used to cooperate with the ventilation hole 33 of the peripheral wall 32 of the stove bottom shell to form a through ventilation channel. This ventilation channel can effectively discharge the combustion exhaust gas, introduce fresh air, maintain the air pressure balance and suitable temperature environment inside the stove, thereby improving the performance stability and reliability of the entire stove and extending the service life of the product.

[0135] In terms of the design of the connection structure between the support frame 621 and the stove bottom shell 3, in order to achieve a convenient and fast assembly process, a matching pre-installed structure is provided between the two. Specifically, a claw 6213 extending upward is provided on the bottom wall 6212 of the support frame 621, and a claw perforation (not shown in the figure) is correspondingly provided on the chassis 31 of the stove bottom shell. The claw 6213 is preferably a spring structure, the upper end of the claw 6213 is bent toward the side wall 6211, and the distance between the upper end of the claw 6213 and the side wall 6211 is less than the distance between the lower end and the side wall 6211. When performing the connection operation between the support frame and the stove bottom shell, first align the claw of the support frame and pass through the claw perforation of the bottom shell of the stove. Since the claw has a certain elastic deformation ability, in the process of passing through the claw perforation, the claw will undergo moderate elastic deformation. After the claw passes through the claw perforation, it can reopen by relying on its own elastic recovery force, thereby forming a stable pre-installed structure. This pre-installation method does not require the use of complex tools or additional connectors. The initial positioning and connection can be quickly achieved through the clever cooperation of the claws and the perforations, which greatly improves the assembly efficiency. After the pre-installation is completed, the support frame is connected to the bottom shell of the stove using the adjustment rod. Since the claws pass through the bottom shell of the stove, the design of the pre-installation structure will not affect the relative height adjustment between the support frame and the bottom shell of the stove by the adjustment rod, which further ensures the stability and reliability of the entire connection structure.

[0136] In terms of the type of adjustment rod 622, it is preferred to use a screw rod, which has high-precision adjustment characteristics. The screw rod and the support frame or the bottom shell of the stove are closely matched through a threaded connection. With the help of the mature and precise transmission principle of spiral transmission, the vertical distance between the support frame and the bottom shell of the stove can be accurately fine-tuned. Through this structural design, the entire adjustment component can adjust the position of the adjustable panel in real time with a highly flexible and precise control strategy, thereby effectively adapting to different installation requirements and diversified usage scenarios, providing a solid technical guarantee for the stable operation of the stove without a cooktop in different countertop environments.

[0137] A further solution is, Figure 6 and Figure 7 As shown, the stovetop-less cooker of the present invention includes a knob installation assembly 7, which mainly includes:

[0138] At least a part of the knob mounting sleeve 71 is used to play a key role in supporting the table 4. A through hole 710 is provided in the knob mounting sleeve 71 to install the knob shaft and / or the valve stem 81 of the switch valve 8.

[0139] The knob bracket 72 has at least a portion thereof disposed under the countertop and fixedly connected to the stove bottom shell 3, thereby constructing a reliable basic support frame for the entire knob installation assembly; the knob installation sleeve 71 and the knob bracket 72 are detachably connected.

[0140] The height of the knob mounting sleeve 71 relative to the knob bracket 72 is adjustable. That is to say, the upper and lower distances between the upper end of the knob mounting sleeve 71 and the knob bracket 72 are adjustable. This adjustable distance feature enables the assembly to be flexibly adapted to countertops of different thicknesses, further expanding the versatility and adaptability of stoves without cooktops in a variety of installation environments. Whether it is an ultra-thin countertop or a thicker countertop, the knob mounting assembly can be perfectly matched with the countertop through simple adjustment operations, ensuring that the knob can maintain a good operating feel and ease of use at different countertop heights.

[0141] In addition, the knob mounting sleeve 71 can be partially supported above the table top 4, and is detachably connected to the knob bracket 72 below the table top 4, and the upper and lower distances are adjustable. This design enables the knob mounting assembly to also have the function of clamping the table top.

[0142] There are multiple options for the position where the knob mounting sleeve 71 is connected to the knob bracket 72, which can be located above the table 4 and / or in the knob mounting hole 42 of the table and / or below the table 4. If the knob mounting sleeve 71 is entirely above the table 4, the upper end of the knob bracket 72 passes through the knob mounting hole 42 of the table from the bottom of the table 4 to connect with the knob mounting sleeve 71; if the knob bracket 72 is entirely below the table 4, the lower end of the knob mounting sleeve 71 passes through the knob mounting hole 42 of the table from the top of the table 4 to connect with the knob bracket 72; if the lower end of the knob mounting sleeve 71 is inserted into the knob mounting hole 42 of the table from the top of the table 4 to the bottom, and the upper end of the knob bracket 72 is inserted into the knob mounting hole 42 of the table from the bottom of the table 4 to the top, the lower end of the knob mounting sleeve 71 is connected with the upper end of the knob bracket 72 in the knob mounting hole 42 of the table. The above installation positions are only examples and are not exhaustive. They can be combined according to the actual structure of the knob installation sleeve and the knob bracket.

[0143] This multi-position optional connection method has significant advantages in practical applications. It can be flexibly adjusted according to different kitchen decoration styles, countertop designs and user habits, further improving the adaptability and user satisfaction of cooktopless stoves in various usage scenarios.

[0144] A further solution is that the knob mounting sleeve 71 includes a cylindrical connector 711 and a support ring 712 arranged on the outer periphery of the connector 711. The lower end of the connector 711 is connected to the knob bracket 72. The support ring 712 is used to support on the table 4. The support ring 712 is annular and is sleeved on the outer periphery of the connector 711. Preferably, the inner ring is provided with an internal thread, which is threadedly connected to the connector 711, or is an integral structure with the connector 711.

[0145] Preferably, the knob mounting sleeve 71 and the knob bracket 72 are connected by threads.

[0146] Preferably, the knob bracket 72 includes a mounting frame 721 fixedly connected to the stove bottom shell 3 and a connecting sleeve 722 provided on the mounting frame 721 and protruding upward. The connecting sleeve 722 is used to extend into the knob mounting hole 42 of the tabletop and connect to the connector 711 of the knob mounting sleeve 71. The outer diameter of the connecting sleeve 722 preferably matches the knob mounting hole 42 of the tabletop. The connecting sleeve 722 has an internal thread, and the lower end of the connector 711 of the knob mounting sleeve 71 is provided with an external thread, which can match the connecting sleeve 722. When installing, tightening the threaded match can achieve the connection and fixation of the stove bottom shell 3 and the tabletop 4 at the knob. Further preferably, the connecting sleeve 722 is fixed to the mounting frame 721 by screws or pins, or the connecting sleeve 722 and the mounting frame 721 are an integral structure.

[0147] The threaded connection has significant advantages such as stable connection, precise adjustment, and convenience. The present invention uses the innovative design of the knob installation assembly to further significantly improve the stability of the stove bottom shell fixedly installed under the countertop. By flexibly adjusting the upper and lower relative distances between the knob installation sleeve and the knob bracket, as well as the multi-position optional connection method and the stable characteristics of the threaded connection, the assembly can perfectly adapt to countertops of different thicknesses and different design styles, further comprehensively improving the versatility and adaptability of stoves without cooktops in a variety of complex installation environments, providing users with a more convenient, safe and stable use experience.

[0148] Further, such as Figure 7 As shown, the adjustable panel 61 is provided with an adjustable panel knob mounting hole 613 , and the connecting sleeve 722 of the knob bracket 72 passes through the adjustable panel knob mounting hole 613 , extends into the knob mounting hole 42 of the table top 4 , and is connected to the connector 711 of the knob mounting sleeve 71 .

[0149] like Figure 8 As shown, the installation method of the stove without a cooktop of the present invention comprises the following steps:

[0150] S1, connecting the first bracket 11 of the connecting frame 1 to the assembly portion 30 of the stove bottom shell 3;

[0151] First, the first bracket 11 is precisely and firmly connected to the assembly part 30 of the bottom shell of the cooker. This step requires the installer to strictly follow the design requirements and installation specifications to ensure that the connection between the first bracket and the assembly part is tight and there is no looseness or deviation, so as to lay a solid foundation for subsequent installation operations. For example, during the connection process, it is necessary to carefully check the fit of the connection parts, use appropriate tools and connectors, and operate according to the specified torque or connection method to ensure the reliability and stability of the connection.

[0152] Before or after step S1, the internal parts of the cooker, such as the clamping assembly 6, the burner 2, the knob bracket 72, the switch valve 8, etc., are installed on the cooker bottom shell 3, ensuring that the distance between the adjustable panel and the support arm is much greater than the thickness of the table top, and preferably the adjustable panel is adjusted down to the limit position. The above operation completes the assembly of the internal structure of the cooker in advance, provides convenience for the subsequent overall installation, and avoids inconvenience or interference caused by the lack of internal parts or failure to install them in place during the subsequent installation process.

[0153] S2, lift the stove bottom shell 3, rotate the second bracket 12 of the connecting frame, so that the support arm 121 passes through the table top installation hole 41 from the bottom of the table top 4 upward;

[0154] In this step, carefully lift the stove bottom shell 3. At this time, you need to pay attention to keeping the stove bottom shell stable to avoid damage to components or difficulty in installation due to shaking or tilting. Fig. 9 As shown, first, according to the design structure that the second bracket 12 rotates relative to the first bracket 11, the second bracket 12 is rotated so that the support arm 121 equipped with the second bracket 12 can smoothly and accurately penetrate the table top installation hole 41 from the bottom to the top of the table top 4. During the rotation process, the installer needs to control the rotation force and angle to ensure that the support arm can accurately align with the table top installation hole.

[0155] In the process of pushing the support arm 121 of the second bracket 12 as a whole from bottom to top into the table mounting hole 41, the hole wall of the table mounting hole 41 will first apply an abutting force to the extended end of the support arm 121, and this force will prompt the upper end of the connecting arm 122 of the second bracket to overcome the elastic force of the torsion spring and rotate in the direction close to the first bracket 11. At this time, the lower end of the connecting arm 122 will move away from the first bracket 11; in the process of the support arm 121 entering the table mounting hole 41 and moving upward, the extended end of the support arm 121 and the connecting arm 122 may simultaneously abut against the hole wall of the table mounting hole 41 to produce deformation. Since the second bracket 12 is formed by bending a sheet metal part as a whole, it has a certain elastic deformation, which can further ensure that the support arm 121 passes through the table mounting hole 41 during installation.

[0156] S3 , the second bracket 12 is rotated in the opposite direction, and the support arm 121 is supported on the periphery of the table top installation hole 41 , so that the stove bottom shell 3 is suspended below the table top 4 .

[0157] When the support arm 121 passes through the table mounting hole 41 as a whole, the force exerted by the hole wall on the support arm 121 disappears, and the upper end of the second bracket 12 returns to its initial state due to the elastic force of the torsion spring and rotates in the opposite direction away from the first bracket 11. At this time, the support arm 121 is supported on the outer periphery of the table mounting hole 41, so that the hoisting of the stove bottom shell 3 is realized (see Fig. 9 ).

[0158] After step S3, the clamping assembly 6 is adjusted, and the height of the adjustable panel 61 is adjusted upwards so that it fits against the lower surface of the tabletop 4, and the cooker bottom shell 3 is initially fixed by cooperating with the support arm 121. This step can further enhance the stability of the cooker bottom shell installation, reduce the possibility of shaking, ensure the firmness and safety of the entire cooker without a cooktop after installation, and lay a good foundation for subsequent fine debugging and use.

[0159] Then, install the knob installation sleeve 71 on the table 4, connect the knob installation sleeve 71 with the knob bracket 72, install the knob 82, fix the liquid tray 5 on the burner 2, preferably by screwing and fixing; then install the ignition cover 21 and the pot bracket 9, and complete the installation of the stove without a stove top on the table (see Fig.10 and Fig.11 ).

[0160] The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation scheme in the above embodiment can also be further combined or replaced. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the scope of the solution of the present invention.
