Description

Technical Field

[0001] The present invention relates to the field of dispensing, and specifically to a granular dispensing mechanism. Background Art

[0002] Some existing dispensing bottle caps are provided with a plurality of constant-volume grooves and dispense medicine by circumferential rotation. For example, a porous metering device for granular preparations disclosed in the patent document CN110589037A. Among them, dispensing refers to the process of dispensing granular products, not limited to the dispensing of pharmaceutical granules. It is difficult to set the zero position for this kind of device, and it is easy to deviate from the positioning point after being touched during use, resulting in spilled granules.

[0003] In order to overcome the above defects, a push-pull type dispensing bottle cap has appeared in the prior art. There are problems of low dispensing efficiency and low dispensing accuracy in each dispensing process in this kind of dispensing bottle cap with a designed material dropping port. Summary of the Invention

[0004] The purpose of the present invention is to provide a granular dispensing mechanism to solve the problems of difficult zero position setting, easy granule spilling, low dispensing efficiency and low dispensing accuracy existing in the granular dispensing mechanism in the prior art.

[0005] To solve the above technical problems, the present invention specifically provides the following technical solutions:

[0006] A granular dispensing mechanism, the granular dispensing mechanism includes: a feeding plate, a material transporting plate and a material dropping plate which are sequentially arranged in contact along the material dropping direction. A material transporting gap is formed between the feeding plate and the material dropping plate, and the material transporting plate can perform a push-pull movement within the material transporting gap;

[0007] In the direction perpendicular to the push-pull direction of the material transporting plate, a plurality of feeding ports are arranged at intervals on the feeding plate, a plurality of groups of parallel material transporting ports are arranged on the material transporting plate, and a plurality of groups of material dropping ports are arranged on the material dropping plate; along the push-pull direction of the material transporting plate, each group of material transporting ports includes a plurality of material transporting ports, and each group of material dropping ports includes a front material dropping port and a rear material dropping port; along the material dropping direction, a group of material transporting ports and a group of material dropping ports are sequentially corresponding below the feeding port. Along the push-pull direction of the material transporting plate, the front material dropping port and the rear material dropping port in the same column are located on both sides of the feeding port; during the push-pull process of the material transporting plate, the material transporting port can pass through the front material dropping port, the rear material dropping port or the feeding port;

[0008] The final state of the material transporting plate during the advancing movement is the zero position state; when the material transporting plate is in the zero position state, the material transporting plate can be fixed in the material transporting gap, and the feeding port is in a closed state.

[0009] Preferably, the material conveying plate can only be pushed and pulled through one opening at one end of the material conveying gap, and the rear blanking port, the feeding port, and the front blanking port are arranged in sequence along the pulling direction of the material conveying plate.

[0010] Preferably, along the pulling direction of the material conveying plate, each row of material conveying port groups includes the material conveying port A at the forefront and the material conveying port B at the rearmost end; when the material conveying plate is in the zero position state, along the pulling direction of the material conveying plate, the material conveying port A is located behind the rear blanking port, or the material conveying port A overlaps with the rear blanking port.

[0011] Preferably, when the material conveying plate is in the maximum pulled-out state, the distance between the material conveying port B and the front blanking port is the distance for the material conveying plate to push and pull 2 - 4 grids of the material conveying ports.

[0012] Preferably, the material conveying plate can be pushed and pulled through the openings at both ends of the material conveying gap respectively, the feeding port is located in the middle of the feeding plate, and the front blanking port and the rear blanking port in each row of blanking port groups are symmetrically arranged with respect to the feeding port.

[0013] Preferably, each row of the material conveying port groups includes a first material conveying port group and a second material conveying port group; when the material conveying plate is in the zero position state, the feeding port is located between the first material conveying port group and the second material conveying port group.

[0014] Preferably, when the material conveying plate is in the zero position state, the first material conveying port group includes the material conveying port C closest to the feeding port and the material conveying port D farthest from the feeding port, the second material conveying port group includes the material conveying port E closest to the feeding port and the material conveying port F farthest from the feeding port, the front blanking port is located between the material conveying port D and the feeding port, and the rear blanking port is located between the material conveying port F and the feeding port;

[0015] When the material conveying plate is in the maximum pulled-out state, the distance between the material conveying port D and the rear blanking port is the distance for the material conveying plate to push and pull 2 - 4 grids of the material conveying ports; or, the distance between the material conveying port F and the front blanking port is the distance for the material conveying plate to push and pull 2 - 4 grids of the material conveying ports.

[0016] Preferably, the distance between the feeding port and the front blanking port is the distance for the material conveying plate to push and pull 2 - 4 grids of the material conveying ports.

[0017] Preferably, a notch is provided on the feeding plate, and a clamping post is provided on the material conveying plate. When the material conveying plate is in the zero position state, the clamping post can be clamped in the notch.

[0018] Preferably, a through hole is provided on the feeding plate. When the material conveying plate is in the zero position state, a bolt can be arranged in the through hole to fix the material conveying plate.

[0019] Preferably, along the blanking direction, the adapter and the feed housing are sequentially arranged on the feed plate;

[0020] The feed housing is provided with an RFID tag and a detection piece;

[0021] The number of columns of the material conveying port group is 2 - 14, and the number of material conveying ports in each column of the material conveying port group is 2 - 30.

[0022] The working process of the particle dispensing mechanism provided by the present invention is as follows: When no dispensing is required and the material conveying plate is in the zero position state, the material conveying plate can be fixed in the material conveying gap, and the feed port is in a closed state. At this time, the material conveying port may not store particulate material.

[0023] When dispensing is required, the material conveying plate and the material conveying gap are separated, and the material conveying plate can be driven to be pulled outwards. During the pulling process, when the material conveying port passes through the blanking port, the particulate material on the feed plate can pass through the blanking port and be filled into the material conveying port. When the material conveying port moves above one of the front blanking port and the rear blanking port, the particulate material can be discharged through the front blanking port or the rear blanking port until the material conveying plate is pulled out to the maximum distance. At this time, the material conveying plate is in the maximum pulled - out state;

[0024] After the material conveying plate is in the maximum pulled - out state, in the reverse process, the material conveying plate is pushed into the material conveying gap. During the pushing process, when the material conveying port passes through the feed port, the particulate material on the feed plate can pass through the feed port and be filled into the material conveying port. When the material conveying port moves above the other one of the front blanking port and the rear blanking port, the particulate material can be discharged through the front blanking port or the rear blanking port until the material conveying plate returns to the zero position state, thus completing one - stroke dispensing; If the next dispensing action is required, the above - mentioned actions can be repeated.

[0025] Among them, the front blanking port and the rear blanking port in each column of the blanking port group can respectively dispense different packaging bags or packaging boxes. Of course, the front blanking port and the rear blanking port in the same column of the blanking port group can also dispense the same packaging bag or packaging box; In addition to the above - mentioned method, if there are multiple columns of blanking port groups, the two front blanking ports or the two rear blanking ports in adjacent columns of blanking port groups can also dispense the same packaging bag or packaging box; Thus, it can be seen that in the specific dispensing process, the matching relationship between the front blanking port and the rear blanking port and the packaging bag or packaging box can be adjusted as needed. As Figure 4 shown, this mechanism can simultaneously dispense 2 packaging bags or packaging boxes, or can simultaneously dispense 4 packaging bags or packaging boxes.

[0026] In addition, the above-mentioned material conveying plate can push and pull an integer multiple of the distance between the material conveying ports when adjusting the same packaging bag or box, so as to achieve the blanking of an integer multiple of the material conveying ports for the same packaging bag or box; of course, it is also possible to control the pushing distance of the material conveying plate to achieve the blanking of a non-integer multiple of the material conveying ports for the same packaging bag or box, making the blanking more flexible.

[0027] Compared with the existing circumferentially rotating adjusting bottle cap, the present invention uses a push-pull type for adjustment. When the material conveying plate is in the zero position state, the material conveying plate can be fixed in the material conveying gap, effectively solving the defects of difficult zero position setting and easy particle spilling.

[0028] Compared with the existing push-pull type adjustment mechanism:

[0029] First of all, the present invention adds a blanking port, that is, each column of blanking port groups includes a front blanking port and a rear blanking port, thus greatly increasing the blanking amount of one action. It can achieve blanking from one of the front blanking port and the rear blanking port when pulling out; blanking from the other of the front blanking port and the rear blanking port when pushing in, greatly reducing the empty stroke, realizing blanking at the feeding port side and the blanking port side, and improving the adjustment efficiency.

[0030] Under the condition of the same size in the push-pull direction, the blanking amount of one action is multiple times that of setting a single blanking port device, enabling most kinds of particles to meet the blanking amount with only one action, improving the adjustment efficiency. For example, in the existing push-pull type adjustment mechanism, only one blanking port and one feeding port are provided, and only 7 material conveying ports can be blanked between the blanking port and the feeding port. In this application, one blanking port is divided into a front blanking port and a rear blanking port, and the positions between the front blanking port, the rear blanking port and the feeding port are adjusted, so that each column of blanking port groups can complete the blanking of 20 material conveying ports, making the blanking amount of one action 2.86 times that of setting a single blanking port device.

[0031] Secondly, the present invention adjusts the caliber of the material conveying ports. In the existing push-pull type adjustment mechanism, the material conveying ports can accommodate several milliliters of materials, while in this application, the material conveying ports in each column of material conveying port groups are more refined, and each material conveying port can accommodate 0.04 - 0.2 milliliters of materials, making the adjustment more accurate.

[0056] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0057] The present invention provides a particle adjustment mechanism, as Figure 1-2 shown. The particle adjustment mechanism includes: a feeding plate 1, a material transport plate 3, and a blanking plate 13 that are sequentially attached along the blanking direction. A material transport gap is formed between the feeding plate 1 and the blanking plate 13, and the material transport plate 3 can perform a pushing and pulling movement within the material transport gap;

[0058] In the direction perpendicular to the pushing and pulling direction of the material transport plate 3, at least one feeding opening 10 is spacedly arranged on the feeding plate 1. Multiple rows of material transport opening groups that are parallel to each other are arranged on the material transport plate 3, and at least one row of blanking opening groups is arranged on the blanking plate 13; along the pushing and pulling direction of the material transport plate 3, each row of material transport opening groups includes multiple material transport openings 9, and each row of blanking opening groups includes a front blanking opening 11 and a rear blanking opening 12; along the blanking direction, a material transport opening group and a blanking opening group are sequentially corresponding below the feeding opening 10. Along the pushing and pulling direction of the material transport plate 3, the front blanking opening 11 and the rear blanking opening 12 in the same row are located on both sides of the feeding opening 10; during the pushing and pulling process of the material transport plate 3, the material transport opening 9 can pass through the front blanking opening 11, the rear blanking opening 12, or the feeding opening 10;

[0059] The final state of the material transport plate 3 during the advancing movement is the zero position state; when the material transport plate 3 is in the zero position state, the material transport plate 3 can be fixed in the material transport gap, and the feeding opening 10 is in a closed state.

[0060] Among them, in the above embodiments, when the material conveying plate 3 is in the zero position state, the material conveying port may or may not store materials. For the convenience of accurately controlling each adjustment, preferably, when the material conveying plate 3 is in the zero position state, the material conveying port does not store materials.

[0061] In addition, in the present invention, the number of the feed ports 10 and the number of rows of the blanking port groups are not specifically limited. The feed port 10 may be one or more than two. Similarly, the number of rows of the blanking port groups may be one row or more than 2 rows.

[0062] As Figure 11-13 shown, when there is one feed port 10, the granular materials above the feed plate 1 can enter multiple material conveying ports 9 through one feed port 10. At this time, the number of rows of the lower blanking port group may be one or multiple. If the number of the blanking port groups is multiple, the blanking port groups and the material conveying port groups are in one-to-one corresponding positions, so that the granular materials can fall from the material conveying ports 9 into the front blanking ports 11 and the rear blanking ports 12; if the number of the blanking port groups is 1, the granular materials respectively fall into 1 front blanking port 11 and 1 rear blanking port 12 after passing through the material conveying ports 9. Due to the existence of multiple rows of material conveying port groups, as long as the packaging bags or packaging boxes are facing different material conveying port groups, separate adjustments can be achieved.

[0063] Similarly, there may be multiple feed ports 10. As Figure 3-10 shown, there are 2 feed ports 10. Multiple feed ports 10 are in one-to-one correspondence with the lower material conveying port groups, so that the granular materials enter the material conveying ports 9. At this time, the number of rows of the lower blanking port group may be one or multiple. If the number of the blanking port groups is multiple, as Figure 3-5 shown, there are 2 groups of blanking port groups, then the blanking port groups and the material conveying port groups are in one-to-one corresponding positions, so that the granular materials can fall from the material conveying ports 9 into the front blanking ports 11 and the rear blanking ports 12; if the number of the blanking port groups is 1, the granular materials respectively fall into 1 front blanking port 11 and 1 rear blanking port 12 after passing through the material conveying ports 9. Due to the existence of multiple rows of material conveying port groups, as long as the packaging bags or packaging boxes are facing different material conveying port groups, separate adjustments can be achieved.

[0064] In the present invention, the end of the material conveying gap may be open at one end or open at both ends. For different opening situations, the material conveying plate 3 can be pushed and pulled only through one opening or can be pushed and pulled respectively through two openings. For the convenience of controlling the positioning of the material conveying plate 3 in the zero position state and facilitating the smooth transition between the pushing and pulling state and the zero position state, preferably, as Figure 2-10As shown, the material conveying plate 3 is pushed and pulled only through the opening at one end of the material conveying gap, and the rear blanking port 12, the feeding port 10, and the front blanking port 11 are arranged in sequence along the pulling-out direction of the material conveying plate 3. Thus, as long as it is pushed and pulled through the same opening, the material can be discharged from the front blanking port 11 when the material conveying plate 3 is pulled out, and the material can be discharged from the rear blanking port 12 when the material conveying plate 3 is pushed in.

[0065] On the basis of the above embodiment, in order to enable the material conveying ports 9 on the material conveying plate 3 to convey materials to the rear blanking port 12 after the pushing action is completed, thereby increasing the amount of material discharged from the rear blanking port 12, preferably, as Figure 5 shown, along the pulling-out direction of the material conveying plate 3, each column of material conveying port groups includes the frontmost material conveying port A 91 and the rearmost material conveying port B 92; when the material conveying plate 3 is in the zero position state, along the pulling-out direction of the material conveying plate 3, the material conveying port A 91 is located behind the rear blanking port 12, or the material conveying port A 91 overlaps with the rear blanking port 12.

[0066] In the present invention, in order to avoid forming a channel among the material conveying port 9, the front blanking port 11, and the feeding port 10, thereby avoiding the direct entry of granular materials from the feeding port 10 and the front blanking port 11 into the packaging bag or the packaging box, preferably, when the material conveying plate 3 is in the maximum pulled-out state, the distance between the material conveying port B 92 and the front blanking port 11 is the distance of pushing and pulling the material conveying plate 3 by 2 - 4 grids of the material conveying port 9 (here, the distance between the material conveying port B 92 and the front blanking port 11 refers to the distance between the center of the material conveying port B 92 and the center of the front blanking port 11, and the same explanation applies to the distance between the material conveying port B 92 and the front blanking port 11 in other places), that is to say, there are 2 - 4 grids of the material conveying port 9 that cannot discharge materials to the front blanking port 11 and can only discharge materials to the rear blanking port 12. Thus, this section of the material conveying port 9 between the material conveying port B 92 and the front blanking port 11 can play a role in closing the feeding port 10, thereby avoiding the spillage of granular materials. Thus, not all of the material conveying ports 9 on the material conveying plate 3 can convey materials to the front blanking port 11. Therefore, the amount of material discharged from the front blanking port 11 is 2 - 4 grids less than the transportation amount of the material conveying port 9 compared to the amount of material discharged from the rear blanking port 12.

[0067] Among them, in Figure 7 , when the material conveying plate 3 is in the maximum pulled-out state, the distance between the material conveying port B 92 and the front blanking port 11 is the distance of pushing and pulling the material conveying plate 3 by 2 grids of the material conveying port 9; when the material conveying plate 3 is pulled out by ≥3 grids of the material conveying port 9, the material starts to be discharged from the front blanking port 11. After returning to the zero position state, the total number of grids of material discharged by each column of blanking port groups is 2*N - 2 (N is the total number of grids of the material conveying port 9 in each column of blanking port groups).

[0068] InFigure 10 In this case, when the material conveying plate 3 is in the maximum pulled-out state, the distance between the material conveying port B 92 and the front blanking port 11 is the distance for the material conveying plate 3 to push and pull 3 grids of the material conveying port 9; when the material conveying plate 3 is pulled out by ≥4 grids of the material conveying port 9, blanking starts from the front blanking port 11. After returning to zero, the total number of blanking grids for each column of blanking port groups is 2*N - 3 (N is the total number of grids of the material conveying port 9 in each column of blanking port groups).

[0069] Of course, in addition to the above-mentioned material conveying plate 3 being pushed and pulled through one opening, in order to make the front blanking port 11 and the rear blanking port 12 achieve the same blanking amount, preferably, as Figure 11-13 the material conveying plate 3 can be pushed and pulled through the two openings at both ends of the material conveying gap respectively. The feed port 10 is located in the middle of the feed plate 1. The front blanking port 11 and the rear blanking port 12 in each column of blanking port groups are symmetrically arranged with respect to the feed port 10. By the symmetric arrangement of the front blanking port 11 and the rear blanking port 12 in each column of blanking port groups with respect to the feed port 10, the front blanking port 11 and the rear blanking port 12 can achieve the same blanking amount, and thus it is convenient to adjust the amount of granular material in each packaging bag or packaging bottle.

[0070] In the above embodiment, in order to ensure that no granular material is stored in the material conveying port when the material conveying plate is in the zero position state, preferably, as Figure 11 shown, each column of the material conveying port groups includes a first material conveying port group and a second material conveying port group; when the material conveying plate 3 is in the zero position state, the feed port 10 is located between the first material conveying port group and the second material conveying port group.

[0071] On this basis, in order to ensure that the feed port 10 in each column of material conveying port groups can completely blank the front blanking port 11 and the rear blanking port 12, preferably, as Figure 11As shown in the figure, when the material conveying plate 3 is in the zero position, the first material conveying port group includes the material conveying port C 94 closest to the feeding port 10 and the material conveying port D 93 farthest from the feeding port 10. The second material conveying port group includes the material conveying port E 95 closest to the feeding port 10 and the material conveying port F 96 farthest from the feeding port 10. The front blanking port 11 is located between the material conveying port D 93 and the feeding port 10, and the rear blanking port 12 is located between the material conveying port F 96 and the feeding port 10. When the material conveying plate 3 is in the maximum pulled-out state, the distance between the material conveying port D 93 and the rear blanking port 12 is the distance for the material conveying plate 3 to push and pull 2 - 4 grids of the material conveying port 9 (the distance between the material conveying port D 93 and the rear blanking port 12 refers to the distance between the center of the material conveying port D 93 and the center of the rear blanking port 12, and the same explanation applies to the distance between the material conveying port D 93 and the rear blanking port 12 at other positions). That is to say, there are 2 - 4 grids of the material conveying port 9 that cannot blank the rear blanking port 12 and can only blank the front blanking port 11. Or, the distance between the material conveying port F 96 and the front blanking port 11 is the distance for the material conveying plate 3 to push and pull 2 - 4 grids of the material conveying port 9 (the distance between the material conveying port F 96 and the front blanking port 11 refers to the distance between the center of the material conveying port F 96 and the center of the front blanking port 11, and the same explanation applies to the distance between the material conveying port F 96 and the front blanking port 11 at other positions). That is to say, there are 2 - 4 grids of the material conveying port 9 that cannot blank the front blanking port 11 and can only blank the rear blanking port 12.

[0072] In the case where the push-pull plate 3 is pushed and pulled only through one opening, since the feeding port 10 needs to be closed through the material conveying port 9, in a push-pull stroke, there are always several grids of the material conveying port 9 that cannot blank the front blanking port 11 and can only blank the rear blanking port 12. In this embodiment, during the process of pulling the material conveying port D 93 outwards, the material conveying port F 96 and several grids of the material conveying port 9 near it cannot blank the front blanking port 11. However, during the process of pulling the material conveying port F 96 outwards, the material conveying port F 96 and several grids of the material conveying port 9 near it can blank through the rear blanking port 12, thus ensuring that several grids of the material conveying port 9 near the material conveying port F 96 have the opportunity to blank in a push-pull stroke. Similarly, the material conveying port D 93 and the material conveying port 9 near it also have the opportunity to blank in a push-pull stroke. Thus, in a push-pull stroke, the feeding port 10 in each column of the material conveying port group can be completely blanked through the front blanking port 11 and the rear blanking port 12, thereby increasing the blanking amount in a single stroke.

[0073] In the present invention, in order to avoid the overflow of the granular material directly from between the feed inlet 10 and the front blanking opening 11, preferably, the distance between the feed inlet 10 and the front blanking opening 11 is the distance that the material conveying plate 3 pushes and pulls the material conveying opening 9 by 2-4 grids (the distance between the feed inlet 10 and the front blanking opening 11 refers to the distance between the center of the feed inlet 10 and the center of the front blanking opening 11).

[0074] In the above embodiment, the manner of fixing the material conveying plate 3 to the material conveying gap is not specifically limited. However, for the convenience of operation, preferably, a notch 8 is provided on the feed plate 1, and a clamping post 7 is provided on the material conveying plate 3. When the material conveying plate 3 is in the zero position state, the clamping post 7 can be clamped in the notch 8. When the material conveying plate 3 is in the zero position state, the clamping post 7 is clamped in the notch 8 to fix the position of the material conveying plate 3; when the material conveying plate 3 is in the push-pull state, the clamping post 7 disengages from the notch 8, thereby releasing the movement obstacle of the material conveying plate 3 in the push-pull direction.

[0075] In addition to the above manner in which the clamping post 7 and the notch 8 cooperate, other elastic snap-fastener methods can also be adopted in the present invention to achieve the fixation of the material conveying plate 3 in the push-pull direction; of course, the specific installation position of the elastic snap-fastener unit can also have a wide selection. In addition to the setting positions of the clamping post 7 and the notch 8, it can also be set on other components, and no mandatory limitation is imposed thereon.

[0076] Of course, in addition to the above manner in which the clamping post 7 and the notch 8 cooperate, other methods can also be adopted to fix the material conveying plate 3. Preferably, the material conveying plate is fixed by a bolt in the direction perpendicular to the push-pull direction. Specifically, the granular material adjustment mechanism further includes a bolt assembly. When the material conveying plate 3 is in the zero position state, the bolt assembly can fix the position of the material conveying plate 3; when the material conveying plate 3 is in the push-pull state, the bolt assembly is separated from the material conveying plate 3. Among them, when the material conveying plate 3 is in the zero position state, the bolt assembly exerts a blocking force on the material conveying plate 3 to fix the position of the material conveying plate 3. For example, the material conveying plate 3 is provided with a bolt hole, and the bolt can enter the bolt hole. When the material conveying plate 3 needs to be pushed and pulled, the bolt can rebound so that the bolt and the bolt hole are separated, thereby releasing the movement obstacle of the material conveying plate 3 in the push-pull direction.

[0077] Among them, the specific installation position of the bolt assembly can also have a wide selection and can be set on, for example, Figure 1 the feed housing 4 as shown, or can also be set on other components, and no mandatory limitation is imposed thereon in the present invention.

[0078] In the present invention, in order to facilitate the smooth entry of the granular material in the storage bottle onto the feed plate 1, preferably, along the material dropping direction, the adapter 2 and the feed housing 4 are sequentially arranged on the feed plate 1. Thus, through the guiding and connecting functions of the adapter 2 and the feed housing 4, it can be ensured that the granular material in the storage bottle can smoothly enter the feed plate 1.

[0079] In addition, in order to identify different granular materials, preferably, an RFID tag 5 and a detection piece 6 are arranged on the feed housing 4; the RFID tag 5 can identify and confirm the identity information of the storage bottle, and the detection piece 6 can receive the information detected by the RFID tag 5 and then judge whether the dispensed granular material is correct, thus ensuring the correctness of the dispensing.

[0080] Finally, in the present invention, there are no specific limitations on the number of columns of the material conveying port group and the number of material conveying ports 9 in each column of the material conveying port group. However, considering the size, cost, and dispensing efficiency of the mechanism, the number of columns of the material conveying port group is 2 - 14, and the number of material conveying ports 9 in each column of the material conveying port group is 2 - 30.

[0081] The above embodiments are only exemplary embodiments of the present application and are not used to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present application, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present application.
