[0050] In addition, if there are these terms "first", "second", these terms are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated.

In the description of the application, if there are terms "a plurality of", the meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise explicitly specified and limited.

[0054] In the related art, the adjusting device structure for covering or opening the exhaust port is mostly complex, which can cause the problems of inconvenient maintenance and excessive size of the cooking device. In addition, the adjusting device almost does not consider the impact of steam on the exhaust port, and there is a problem that the fixed covering exhaust port leads to excessive pressure in the cooking cavity, or the problem that the exhaust port is easily opened too much by steam impact, causing insufficient steam in the cooking cavity. Therefore, the self-adaptive adjusting capability of the above adjusting device is poor.

[0055] Referring to Figure 1 , Figure 1 A partial disassembly structure schematic diagram of an air cooking device according to some embodiments of the application is provided. The air cooking device provided by an embodiment of the application can be an air fryer with steam, or a steam and baking integrated machine, or other cooking devices that need to adjust the internal steam amount, but not limited. The air cooking device can include a main body 600, a wind blocking piece 100, a driving assembly 200, and a conversion assembly 300.

[0056] The main body 600 has a ventilation port 601; the wind blocking piece 100 is arranged at the ventilation port 601, and at least part of the wind blocking piece 100 is used to cover the ventilation port 601; the driving assembly 200 is connected with the wind blocking piece 100 to drive the wind blocking piece 100 to switch between the covering state and the opening state; the conversion assembly 300 is arranged between the main body 600 and the driving assembly 200, and the conversion assembly 300 is configured to apply a force to the driving assembly 200 to maintain the wind blocking piece 100 in the covering state or the opening state.

[0057] It can be understood that the ventilation port 601 is usually arranged on the side of the main body 600, for example, can be located on the rear side of the main body 600, to avoid the hot steam flowing out of the ventilation port 601 from burning the user. The wind blocking piece 100 is arranged corresponding to the ventilation port 601, which can be adapted to cover the ventilation port 601, or can be slightly larger than the ventilation port 601 to achieve complete coverage of the ventilation port 601.

[0058] The driving assembly 200 for driving the wind shield 100 to move can be arranged at one end of the rear side of the main body 600 to facilitate user operation in the manual mode. Of course, it can also be arranged at one end of the front side of the main body 600, and a transmission mechanism 212 such as a connecting rod, a gear set or the like can be arranged between the driving assembly 200 and the wind shield 100 to achieve power transmission. This arrangement can effectively reduce the occupied space of the main body 600, facilitating the miniaturization of the air cooking equipment.

[0059] The wind shield 100 provided in the example can be arranged outside the air vent 601, for example, the wind shield 100 can be supported on the outer side of the main body 600 by a support or the like, and the wind shield 100 can be arranged to fit the air vent 601 in the closed state. The wind shield 100 can be arranged at the air vent 601 under the driving of the driving assembly 200, that is, the wind shield 100 is switched between the closed state of closing the air vent 601 and the open state of opening the air vent 601.

[0060] In addition, the wind shield 100 can also be arranged in the air vent 601, and further understood to be arranged at the airflow passage between the inner side wall and the outer side wall of the main body 600.

[0061] The driving assembly 200 provided in the example includes a manual mode and an electric mode, that is, the driving assembly 200 can be rotated by user manual force or driven by a motor to rotate the wind shield 100, so as to switch between the closed state and the open state.

[0062] When the wind shield 100 is rotated to the closed state, that is, the air vent 601 of the main body 600 is closed, the air cooking equipment is in the steam mode at this time. Because there is a large amount of steam in the air cooking equipment, a large air pressure is generated in the inside of the main body 600, which is easy to push the wind shield 100 at the air vent 601 to a large extent, so that a large amount of internal steam is discharged, which is not conducive to the use of the steam mode. In addition, when the wind shield 100 is rotated to the open state, it is easy to be switched to the closed state due to the vibration of the equipment and the like, thereby affecting the use of the air cooking equipment in the barbecue mode. Of course, the above-mentioned wind shield 100 is also easy to be bumped by the driving assembly 200, thereby being in a state that does not conform to the current use scenario.

[0063] Based on the above-mentioned problems, the example also provides a conversion assembly 300 arranged on the main body 600, for example, one end of the conversion assembly 300 can be rotatably arranged on the main body 600, and the other end can be arranged on the driving assembly 200 to adjust the position of the wind shield 100 by following the movement of the driving assembly 200, thereby providing a basis for the wind shield to continuously be in the closed state or the open state.

[0064] More specifically, the conversion assembly 300 can make the driving assembly 200 have a tendency to continue rotating. The conversion assembly 300 can make the driving assembly 200 have a tendency to continue rotating when the wind shield 100 is in the open state, so that the wind shield can be maintained in the open state; similarly, the conversion assembly 300 can make the driving assembly 200 have a tendency to continue rotating when the wind shield 100 is in the closed state, so that the wind shield 100 can be maintained in the closed state. When the wind shield 100 is impacted by the airflow, the wind shield 100 will resist the force provided by the conversion assembly 300 to avoid the wind shield 100 from being opened too wide.

[0065] The conversion assembly 300 in the present example can be a spring, a rubber band, or other components with elasticity, but is not limited in particular.

[0066] The principle that the conversion assembly 300 can continuously provide a force to maintain the wind shield 100 in the closed state or the open state in the present example can be understood as follows: the end of the conversion assembly 300 connected to the driving assembly 200 will rotate with the driving assembly 200, and will pass through a critical point A in the process of rotation, so that the direction of the force acting on the driving assembly 200 by the end is different. Of course, the implementation of the above-mentioned critical point A also needs to be combined with the setting position of the other end of the conversion assembly 300 to be implemented, and can be understood with reference to the following embodiments.

[0067] It should be noted that a stopper can be arranged outside the main body 600 at the vent 601, for example, above the vent 601. The stopper is mainly used to limit the position of the wind shield 100 when the wind shield 100 is opened. This limitation is beneficial to the conversion assembly 300 to provide a continuous force when the wind shield 100 is in the open state. Of course, the limitation can also be achieved by means of the existing structure of the air cooking device, which is not limited herein.

[0068] In addition, in addition to the above-mentioned manner that the driving assembly 200 drives the wind shield 100 to rotate to open or close the vent 601, the driving assembly 200 can also drive the wind shield 100 to approach or move away from the vent 601 to achieve the opening or closing of the vent 601. Specifically, the driving assembly 200 drives the wind shield 100 to move towards the main body 600 until the wind shield 100 is completely closed on the vent 601, so that the wind shield 100 is in the closed state; the driving assembly 200 drives the wind shield 100 to move away from the main body 600, so that the wind shield 100 has a spacing with the vent 601, so that the wind shield 100 is switched to the open state.

[0069] In the present application, by setting the wind shield 100 for closing or opening the ventilation opening 601 at the ventilation opening 601, and by driving the wind shield 100 to move through the driving assembly 200 connected with the wind shield 100, the switching of the wind shield 100 between the closed state of closing the ventilation opening 601 and the open state of opening the ventilation opening 601 is realized, and by setting the conversion assembly 300 between the main body 600 and the driving assembly 200 to provide a continuous force between the two, the continuous force can provide different steering forces in different directions for the wind shield 100 in different states, so that the wind shield 100 is maintained in the closed state or the open state. The air cooking equipment structure provided in the example is simple, easy to assemble and disassemble, replaceable, and can adapt to the case that the pressure difference inside and outside the ventilation opening 601 is large, has strong adaptive adjustment capability, thereby improving the cooking effect of the air cooking equipment in different cooking modes.

[0070] In the following, the air cooking equipment provided by the embodiments of the present application will be described in detail with reference to the accompanying drawings. Figure 1 -Appendix Figure 9 The specific structure of the air cooking equipment provided by the embodiments of the present application will be described in detail.

[0071] In combination Figure 2 and Figure 3 As shown in the drawings, Figure 2 is one of the structure schematic diagrams of the air cooking equipment in the open state of the wind shield provided according to some embodiments of the present application. Figure 3 is another structure schematic diagram of the air cooking equipment in the open state of the wind shield provided according to some embodiments of the present application. In some embodiments, the conversion assembly 300 includes an elastic member 310, the first end of the elastic member 310 is limited to the main body 600, the second end of the elastic member 310 is limited to the driving assembly 200, and the elastic member 310 is configured to provide a continuous elastic force for the driving assembly 200 to maintain the wind shield 100 in the closed state or the open state.

[0072] It can be understood that the first end of the elastic member 310 is arranged on the main body 600 in a relatively static state, and the second end of the elastic member 310 is arranged on the driving assembly 200 and needs to move with the movement of the driving assembly 200, and when the driving assembly 200 moves to different positions, the direction of the force received by the second end of the elastic member 310 and the size of the force received are not the same.

[0073] Specifically, when the driving assembly 200 drives the wind shield 100 to cover the air vent 601, the second end of the elastic member 310 applies an elastic force to the driving assembly 200, so that the driving assembly 200 has a continuous movement. Since the wind shield 100 is blocked by the main body 600 at the air vent 601 and cannot continue to move, but due to the existence of the elastic force, the wind shield 100 is continuously in the covering state, that is, the wind shield 100 continuously resists the steam in the main body 600 under the continuous action of the elastic member 310 to avoid the wind shield 100 from being opened to a large extent.

[0074] Similarly, when the driving assembly 200 drives the wind shield 100 to open the air vent 601, the second end of the elastic member 310 applies an elastic force to the driving assembly 200, so that the driving assembly 200 has a continuous movement. Since the wind shield 100 is blocked by the main body 600 at the open position and cannot continue to move, but due to the existence of the elastic force, the wind shield 100 is continuously in the open state.

[0075] In combination Figures 4-6 As shown, Figure 4 A position schematic view of the elastic member, the fixing rod and the supporting rod in the open state of the wind shield according to some embodiments of the present application. Figure 5 A structure schematic view of the air cooking equipment in the covering state of the wind shield according to some embodiments of the present application. Figure 6 A position schematic view of the elastic member, the fixing rod and the supporting rod in the covering state of the wind shield according to some embodiments of the present application. In some embodiments, when the driving assembly 200 drives the wind shield 100 to switch between the covering state and the open state, the second end of the elastic member 310 corresponds to switch between the first position and the second position; the first position and the second position are respectively located on two sides of a line between the rotation axis of the wind shield 100 and the first end of the elastic member 310.

[0076] It can be understood that the second end of the elastic member 310 extends to a side away from the main body 600 relative to the first end of the elastic member 310, and defines that the second end of the elastic member 310 is in the first position in the covering state of the wind shield 100, the second end of the elastic member 310 is in the second position in the open state of the wind shield 100, and the first position and the second position are respectively located on two sides of a line between the rotation axis of the driving assembly 200 and the first end of the elastic member 310. In one example, the elastic member 310 is a torsion spring, a compression spring or a tension spring.

[0077] For example, the elastic member 310 is a torsion spring. In the first position, the wind shield 100 is in the closed state, and the torsion spring is in the compressed state. The second end of the torsion spring applies a force to the driving assembly 200, so that the wind shield 100 has a tendency to rotate towards the closed air vent 601, thereby achieving the purpose of maintaining the wind shield 100 in the closed state. When the driving assembly 200 drives the wind shield 110 to rotate to open the air vent 601, the direction of the force applied to the driving assembly 200 changes. In the second position, the second end of the torsion spring drives the wind shield 110 to have a tendency to rotate towards the open air vent 601, thereby achieving the purpose of maintaining the wind shield 110 in the open state.

[0078] To more clearly understand the compression process of the second end of the elastic member 310 between the first position and the second position, as shown in some embodiments, the first position and the second position have a critical point on the arc line therebetween; the force direction of the second end of the elastic member 310 between the first position and the critical point is opposite to the force direction between the second position and the critical point. Figure 4 Figure 6 As shown in some embodiments, the first position and the second position have a critical point on the arc line therebetween; the force direction of the second end of the elastic member 310 between the first position and the critical point is opposite to the force direction between the second position and the critical point.

[0079] For example, the elastic member 310 is a torsion spring. The movement trajectory of the second end of the torsion spring between the first position and the second position is a circular arc, and the circular arc has an intersection point with the connecting line, which can be referred to as a critical point A. In the first position, the torsion spring is in the compressed state, and the second end of the torsion spring applies a force to the driving assembly 200. As the driving assembly 200 is driven by an external force, the second end of the torsion spring moves from the first position to the critical point A. The torsion spring is continuously compressed and reaches the maximum compression state at the critical point A. When the second end of the torsion spring passes through the critical point A, the compression degree of the torsion spring decreases, but the torsion spring is still in the compressed state, and the force direction changes. Until the second end moves to the second position. The maintenance of the compressed state of the torsion spring is conducive to continuously applying a force to the driving assembly 200, i.e., the driving assembly 200 has a tendency to rotate in different directions, thereby providing a basis for the wind shield 100 to be continuously in the closed state or the open state.

[0080] It should be noted that the compression deformation degree of the torsion spring can be adjusted when the second end of the torsion spring is at the first position or the second position. Specifically, the compression deformation degree can be set according to the material of the torsion spring, the size of the steam at the air vent 601, etc., which is not limited herein.

[0081] As shown in some embodiments, the first position and the second position have a critical point on the arc line therebetween; the force direction of the second end of the elastic member 310 between the first position and the critical point is opposite to the force direction between the second position and the critical point. Figure 1 ​As shown, in some embodiments, the wind shield 100 comprises a wind shield plate 110; the driving assembly 200 comprises a driving component 210 and a transmission rod 220, one end of the transmission rod 220 is connected with the output end of the driving component 210, and the other end is fixedly connected with the wind shield plate 110; the second end of the elastic member 310 is rotationally arranged on one side of the transmission rod 220.

[0082] Specifically, the area of the wind shield plate 110 can be slightly larger than the area of the air vent 601, so as to ensure that the air vent 601 can be completely blocked in the closed state. One end of the transmission rod 220 is connected with the driving component 210, and the other end is connected with the wind shield plate 110, for example, can be connected with the upper end or the lower end of the wind shield plate 110, so as to drive the wind shield plate 110 to open or close the air vent 601 when the driving component 210 drives the transmission rod 220 to rotate.

[0083] The second end of the elastic member 310 can be arranged on one side of the transmission rod 220, so as to apply elastic force in different directions to the transmission rod 220 in the process of deformation of the second end of the elastic member 310 with the rotation of the transmission rod 220, so as to continuously maintain the wind shield plate 110 in the closed state or the open state through the transmission rod 220.

[0084] In order to facilitate the transmission rod 220 to drive the second end of the elastic member 310 to move, and to facilitate the second end of the elastic member 310 to apply elastic force to the transmission rod 220 along the axial rotation direction thereof. As Figure 4 and Figure 6 As shown in one example, the driving assembly 200 further comprises a fixed rod 230, one end of the fixed rod 230 is fixed to the side surface of the transmission rod 220, and the other end is rotationally connected with the second end of the elastic member 310.

[0085] Specifically, the axial direction of the fixed rod 230 is perpendicular to the axial direction of the transmission rod 220, and the second end of the elastic member 310 is rotationally arranged at one end of the fixed rod 230 away from the transmission rod 220, so that the rotation direction of the transmission rod 220 can be limited by applying force to the fixed rod 230 through the fixed rod 230. An installation hole can be formed in the end portion of the fixed rod 230, so as to facilitate the installation of the second end of the elastic member 310.

[0086] As Figure 5 As shown in some embodiments, the air cooking device further comprises a support seat 400, the support seat 400 is fixed to the main body 600, the support seat 400 is fixed with a support rod 410, one end of the support rod 410 away from the support seat 400 is rotationally connected with the second end of the elastic member 310.

[0087] Specifically, in order to reduce unnecessary deformation of the elastic element 310 along the axial direction of the transmission rod 220, this example brings the support rod 410 and the fixed rod 230 as close as possible without causing interference. Therefore, for ease of understanding, it can be assumed that the first end and the second end of the elastic element 310 are located in the same plane, and the deformation direction of the elastic element 310 is also in this plane, and this plane is perpendicular to the axial direction of the transmission rod 220.

[0088] The support rod 410 is configured to support the rotation of the elastic element 310. One end of the support rod 410 is fixed to the main body 600 via the support base 400; alternatively, it can be directly fixed to the main body 600, which is not a limitation. The other end of the support rod 410 is positioned away from the main body 600 and is used to rotatably connect to the first end of the elastic element 310. Specifically, a mounting hole can be provided at the end of the support rod 410 to facilitate the placement of the first end of the elastic element 310 within the mounting hole.

[0089] Since the force exerted by the elastic element 310 on the fixed rod 230 is to cause the transmission rod 220 to rotate or have a tendency to rotate, in order to reduce the deformation of the elastic element 310 along the axial direction of the transmission rod 220, in this example, the support rod 410 and the fixed rod 230 are arranged close together, and the end of the support rod 410 connected to the elastic element 310 is arranged away from the end of the fixed rod 230, thereby providing a suitable deformation distance for the elastic element 310.

[0090] Taking the torsion spring as an example, the elastic element 310 is explained. Specifically, the first end of the torsion spring passes through the mounting hole at the end of the support rod 410, and the second end of the torsion spring passes through the mounting hole at the end of the fixing rod 230. The main body 600 of the torsion spring is set away from the support rod 410 and the fixing rod 230. This arrangement can provide space for the deformation of the torsion spring and avoid the influence of the rotation of the fixing rod 230. Of course, no specific restrictions are imposed.

[0091] like Figure 2 As shown, in some embodiments, the support 400 is provided with a through hole so that the transmission rod 220 passes through the support 400.

[0092] Specifically, the transmission rod 220 is too long, which is easy to cause the far end of the transmission rod 220, i.e. the end connected with the wind shield 110, to shake, resulting in poor closing effect of the wind shield 110. Therefore, a support seat 400 is arranged between the wind shield 110 and the driving component 210, and a through hole is formed in the support seat 400, so that the transmission rod 220 is arranged in the support seat 400. In order to improve the rotation flexibility of the transmission rod 220 in the support seat 400, lubricating oil can be applied between the support seat 400 and the transmission rod 220, or a bearing can be arranged in the through hole, but no specific limitation is made. The support seat 400 can also support the support rod 410, thereby increasing the assembly convenience with the main body 600.

[0093] As shown in Figure 1 some embodiments, the support seat 400 includes a first body 420 and a second body 430, the first body 420 is fixed to the main body 600, and recesses are formed on opposite sides of the first body 420 and the second body 430 to form a through hole after the first body 420 and the second body 430 are connected.

[0094] Specifically, the support seat 400 is divided into the first body 420 and the second body 430, and recesses are formed on opposite surfaces of the first body 420 and the second body 430, which are matched with the shape of the transmission rod 220. During installation, the first body 420 can be fixed to the main body 600, then the driving assembly 200 is installed, and the transmission rod 220 is placed in the recess of the first body 420, and the support for the transmission rod 220 is formed by connecting the second body 430 with the first body 420. In order to ensure the connection stiffness of the wind shield 100 and the transmission rod 220, they can be integrally formed or pre-tightly connected. Therefore, this kind of arrangement can improve the installation efficiency of the transmission rod 220.

[0095] As shown in Figure 1 some embodiments, the air cooking device further includes at least one sensing piece 500, which is arranged in the support seat 400, and the sensing piece 500 is configured to sense the position of the fixed rod 230 to determine the state of the wind shield 110.

[0096] Specifically, a sensing piece 500 can be installed on the outer end surface of the seat, or on the outer end surface of the second body 430. When the wind shield 100 is in a closed state or an open state, the fixed rod 230 will move to the position of the sensing piece 500 and trigger the sensing piece 500, and the sensing piece 500 can send a signal to the controller in the air cooking device to display the current state of the air vent 601 on the display panel. Of course, two sensing pieces 500 can also be installed on the outer end surface of the second body 430, one sensing the closing of the air vent 601 and the other sensing the opening of the air vent 601, but no specific limitation is made.

[0097] The inductive element 500 can be a microswitch, an infrared sensor, a Hall element, a photodiode, a pressure sensor, etc., to be triggered by the proximity or contact of the fixed rod 230.

[0098] As shown in Figure 6 some embodiments, the driving component 210 includes a rotating handle 211 which is connected to the end of the transmission rod 220, and the driving component 210 is configured to be at least partially exposed to the cooking device to drive the transmission rod 220 to rotate under external force.

[0099] Specifically, the rotating handle 211 is connected to the end of the transmission rod 220, and the rotation of the transmission rod 220 is realized by manually rotating the rotating handle 211. In order to ensure the aesthetics of the cooking device, the wind shield 100 and the conversion assembly 300 can be arranged in the outer shell of the air cooking device. Since the rotating handle 211 needs to be manually rotated, it can be partially exposed to the air cooking device.

[0100] As shown in Figures 7-9 , the driving component 210 includes a rotating handle 211 and a transmission mechanism 212, and the transmission mechanism 212 is arranged between the rotating handle 211 and the transmission rod 220 to transmit the power of the rotating handle 211 to the transmission rod 220. Figure 7 is a structural schematic view of the driving component according to some embodiments of the present application. Figure 8 is a structural schematic view of the driving component according to some embodiments of the present application. Figure 9 is a structural schematic view of the driving component according to some embodiments of the present application. In some embodiments, the driving component 210 includes a rotating handle 211 and a transmission mechanism 212, and the transmission mechanism 212 is arranged between the rotating handle 211 and the transmission rod 220 to transmit the power of the rotating handle 211 to the transmission rod 220.

[0101] Specifically, the rotating handle 211 with a larger volume can be arranged in a position with fewer components in the cooking device or a position convenient for the user to adjust. In order to ensure the effective transmission between the rotating handle 211 and the transmission rod 220, the transmission mechanism 212 is arranged therebetween.

[0102] The transmission mechanism 212 can be a connecting rod structure, as shown in Figure 7 ; it can also be a bevel gear structure with a steering function, as shown in Figure 8 ; of course, it can also be other mechanisms capable of transmitting power, which are not specifically limited here.

[0103] In addition to the above-mentioned manual adjustment mode, the driving assembly 200 can also be a motor, as shown in Figure 9 .

[0104] As shown in Figure 1As shown, in some embodiments, the air cooking device further comprises: an air outlet base 610 embedded on the main body 600 and formed with an air vent 601; an installation groove 611 is configured at one end of the air outlet base 600 away from the main body 600, and the installation groove 611 is used for installing the transmission rod 220; and an air guide piece 620 is fixedly arranged on the air outlet side of the air outlet base 610, and the air guide piece 620 is configured with a plurality of air holes 621; wherein, a sealing piece 700 is arranged between the air guide piece 620 and the air outlet base 610, and at the installation groove 611.

[0105] It can be understood that the wind shield 110 in the above-mentioned embodiments can be arranged outside the air vent 601, or can be arranged in the air flow channel between the inner side of the main body 600 and the outer side of the main body 600, and can also achieve the opening or closing of the air vent 601. The specific arrangement of the wind shield 110 can be set according to the structure and appearance of the actual air cooking device, which is not limited herein.

[0106] When the air vent 601 is completely opened, the fixed rod 230 will trigger the corresponding inductive piece 500, so that the current suitable cooking mode is displayed on the display screen of the cooking device; similarly, when the air vent 601 is closed, the fixed rod 230 will trigger the corresponding inductive piece 500, so that the current suitable cooking mode is displayed on the display screen of the cooking device.

[0107] The arrangement of the air outlet base 610 is conducive to guiding the air flow in the main body 600 out, and the arrangement of the air outlet base 610 can provide support for the installation of the wind shield 110. An installation groove 611 can be formed at the air outlet end of the air outlet base 610, so that the transmission rod 220 connected with the wind shield 110 is placed in the installation groove 611. In addition, a limiting protrusion can be arranged in the area of the air outlet base 610 outside the air vent 601, and the limiting protrusion can support the transmission rod 220 at both ends of the wind shield 110, thereby improving the rotation stability of the wind shield 110.

[0108] In addition, a fixing rib can be arranged at the end of the transmission rod 220, and the limiting rib can abut against the limiting protrusion to limit the movement of the transmission rod 220 along the axial direction.

[0109] In the present example, the arrangement of the air outlet cover not only facilitates the installation of the transmission rod 220 and the wind shield 110, but also can guide the air flow out of the cooking device as much as possible, thereby avoiding damage to the internal components of the cooking device caused by hot steam. The sealing ring arranged between the air outlet cover and the air outlet base 610, and at the installation groove 611, can further prevent the hot steam from overflowing into the cooking device through the gap. In the present example, a plurality of air holes 621 are arranged on the air outlet side of the air outlet base 610, for example, on the outer peripheral surface of the air outlet base 610 close to the outer end, which is conducive to the dispersion and discharge of hot steam.

[0110] Any combination of the technical features in the above embodiments can be made, and for the sake of brevity, not all possible combinations are described above, however, as long as the combination of the technical features does not exist in contradiction, it shall be considered within the scope of the present disclosure.

[0111] The above embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it shall not be understood as a limitation on the patent scope of the present application. It shall be pointed out that, for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, and these shall be within the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
