Description

Technical Field

[0001] This utility model relates to the field of ceramic material sintering equipment. More specifically, this utility model relates to a heat dissipation device for a kiln equipment system, and to a kiln equipment system including the heat dissipation device. Background Technology

[0002] Ceramic materials are typically sintered in high-temperature kilns during production. A pusher kiln is a type of electric kiln. It has a relatively long body with a sintering chamber and feed and discharge ports located at both ends along its length. The pusher kiln primarily uses pushers to move materials (e.g., powdered materials loaded in saggers) from the feed port into the sintering chamber. The materials are then sintered by heating elements (e.g., heating rods) installed within the sintering chamber. The sintered material is then discharged from the discharge port and poured into material bags by the operator.

[0003] During operation, the temperature of the outer wall of a pusher kiln is extremely high, typically reaching 80℃-100℃, and different areas of the outer wall dissipate heat at varying temperatures. Understandably, such high temperatures, when diffused into the air, lead to excessively high ambient temperatures, making it unsuitable for operators to perform tasks such as replacing heating components. Therefore, with increasingly stringent requirements for working environments, it is necessary to find suitable solutions to avoid the adverse effects of the kiln's high-temperature environment on the health and work performance of operators.

[0004] In existing technology, the traditional approach is to isolate the furnace body area of ​​a pusher kiln using enclosed compartments to prevent heat from escaping. The furnace inlet and outlet are located outside the compartments, while ventilation units inside the compartments provide heat dissipation. However, the compartments constructed in this way are complex, occupy a large area, and have poor heat dissipation, making them unsuitable for electric kilns such as pusher kilns. For example, the internal space of such compartments is relatively small, making it difficult to provide sufficient space for operations such as replacing heating components while the pusher kiln is operating. Utility Model Content

[0005] The purpose of this invention is to provide a heat dissipation device for kiln equipment systems to overcome at least one deficiency in the prior art. More specifically, the heat dissipation device according to this invention not only saves space but also reduces the diffusion of a large amount of heat from the outer wall of the kiln body to the interior, thus effectively lowering the indoor temperature and creating a better working environment.

[0020] Compared with the prior art, the heat dissipation device and the kiln equipment system including it according to this utility model have several beneficial technical effects, especially: by setting up a heat dissipation hood and a gas driving unit, as much heat as possible emitted from the top and side walls of the kiln body can be confined in the heat dissipation chamber between the heat dissipation hood and the kiln body, and discharged to the outside through the gas driving unit. This can effectively reduce the indoor temperature of the kiln area by, for example, 5°C-10°C. In addition, the heat dissipation device is cost-effective and can be easily installed above the kiln body, saving floor space and not affecting operations such as replacing heating components. Therefore, it can be applied to kilns such as pusher kilns. Attached Figure Description

[0021] Other features and advantages of this invention will be better understood through the following detailed description of preferred embodiments in conjunction with the accompanying drawings. In the drawings, the same reference numerals denote the same or similar parts.

[0022] Figure 1 This is a YZ cross-sectional schematic diagram of a kiln equipment system according to one embodiment of the present invention.

[0023] Figure 2 This is a schematic diagram of the XZ cross-section of the kiln equipment system.

[0024] Figure 3 This is a schematic diagram of the auxiliary components arranged at the bottom of the heat dissipation shroud of the kiln equipment system.

[0025] The elements in the accompanying drawings are shown for simplicity and clarity and are not necessarily drawn to exact scale. It should be understood that these drawings are not only for explaining and illustrating the present invention, but also, where necessary, for defining the present invention. Detailed Implementation

[0026] The implementation and use of specific embodiments are discussed in detail below. However, it should be understood that the specific embodiments discussed are merely illustrative of particular ways of implementing and using this utility model, and are not intended to limit the scope of this utility model.

[0027] In this manual, the descriptions of the structural positions of various components, such as "up," "down," "top," and "bottom," are not absolute but relative. These directional descriptions are appropriate when the components are in their normal operating positions as shown in the figure; however, these directional descriptions should be changed accordingly when the positions of the components change.

[0028] In this specification, unless otherwise expressly specified and limited, terms such as "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this specification according to the specific circumstances.

[0029] The kiln equipment system involved in this utility model is, for example, a pusher plate kiln system, which can be an electric kiln system. In this specification and drawings, "X" represents the length direction of the kiln body and heat sink of the kiln equipment system (i.e., the direction perpendicular to the paper in the illustrated embodiment), "Y" represents the width direction of the kiln body and heat sink (i.e., the direction perpendicular to the X direction in the horizontal plane), and "Z" represents the height direction of the kiln body and heat sink (i.e., the direction perpendicular to the XY plane). It is understood that the length direction X corresponds to the direction of material travel in the kiln body, and this length direction X does not necessarily have to extend in a straight line; it can also extend along a curve, or bend at a specific position. Furthermore, the kiln body of the pusher plate kiln system and other kiln equipment systems typically extends a relatively long distance in the length direction X, that is, the size of the kiln body in the length direction X is usually at least several times the size in the width direction Y. For example, the size of the kiln body in the length direction X can be at least five times, at least ten times, at least twenty times, or at least thirty times the size in the width direction Y.

[0030] A preferred embodiment of the present invention will now be described with reference to the accompanying drawings.

[0031] like Figure 1As shown, the kiln equipment system includes a kiln 100 and a heat dissipation device. The kiln 100 mainly includes a kiln body 110, a sintering chamber 120, a transmission component 160, multiple heating components, and kiln accessories such as pipes 150. The kiln body 110 has a top wall 113 extending generally along the XY plane, and a first side wall 111 and a second side wall 112 located on opposite sides along the width direction Y and extending generally along the XZ plane. The sintering chamber 120 is formed inside the kiln body 110. The feed inlet and discharge outlet of the sintering chamber 120 are located at both ends of the kiln body 110 along the length direction X. The transmission component 160 is used to carry the material to be sintered (e.g., powdered ceramic material loaded in multiple saggers) and drive the material from the feed inlet into the sintering chamber 120, so that the material passes through the entire sintering chamber 120 along the length direction X and is sintered by multiple heating components arranged in the kiln body 110. The sintered material is finally output from the discharge outlet. In the illustrated embodiment, the heating elements include a first heating element 170 extending through the bottom of the sintering chamber 120 (and positioned below the transmission member 160) and a second heating element 180 extending through the top of the sintering chamber 120. These heating elements are, for example, heating rods extending along the width direction Y, and can be detached along the width direction Y via a first sidewall 111 or a second sidewall 112. It is understood that the construction of the heating elements is not limiting, and in particular, it is not necessary for them to extend across the entire width of the furnace body 110 or the sintering chamber 120, but only that each heating element can be detached via the first sidewall 111 or the second sidewall 112 and can be replaced by suitable means. Furthermore, the kiln 100 may optionally include a first hanging plate 130 and a second hanging plate 140. The first hanging plate 130 is detachably mounted on the first side wall 111 to at least partially shield the first side wall 111 and one end of the heating components. The second hanging plate 140 is detachably mounted on the second side wall 112 to at least partially shield the second side wall 112 and the other end of the heating components. In fact, the first hanging plate 130 and the second hanging plate 140 not only serve a shielding and decorative function but also provide insulation to prevent the kiln body 110 from becoming too cold and to prevent electric shock to operators. A pipe 150 for connecting to the kiln body 110 extends, for example, from the top wall 113.

[0032] In addition, such as Figure 2As shown, along the length direction X, the furnace body includes a heating section 110a, a high-temperature section 110b, and a cooling section 110c arranged sequentially. Heating components are located in the heating section 110a and the high-temperature section 110b. The heating section 110a is used to gradually heat the material to be sintered from room temperature to the target sintering temperature, for example, from room temperature to approximately 1200°C (the target sintering temperature varies depending on the material), and to remove moisture or other volatile substances from the material. The heating component in the heating section 110a can be a heating rod or a metal heating wire, such as an iron-chromium-aluminum resistance wire. The high-temperature section 110b is used to complete the sintering of the material at a high temperature, forming the physicochemical properties of the final product. The temperature of the high-temperature section 110b is, for example, between 1200°C and 1600°C (depending on the material), and the heating component in the high-temperature section 110b is typically a heating rod, such as a silicon carbide rod or a silicon molybdenum rod, to suit high-temperature, high-power heating. The cooling section 110c is used to control the cooling rate of the material after sintering, so as to achieve slow cooling.

[0033] Understandably, the operating temperature of this high-temperature kiln 100 (especially in the high-temperature section 110b) can reach, for example, 1400°C. Furthermore, during operation, heat can diffuse outwards through the first sidewall 111, the second sidewall 112, and the top wall 113, causing the temperatures of these walls to reach, for example, 80°C-100°C. Such high heat diffusion into the air results in excessively high indoor temperatures, a harsh working environment, and makes it impossible for operators to work in this area.

[0034] Therefore, to reduce excessive heat conduction into the room, a heat dissipation device is provided in the kiln equipment system according to this utility model. This heat dissipation device mainly includes a heat dissipation shroud 200 and a gas drive unit 400. The heat dissipation shroud 200 can at least partially cover the top of the furnace body 110 and the first side wall 111 and the second side wall 112 along its length X, so that the space between the heat dissipation shroud 200 and the furnace body 110 forms a heat dissipation chamber 240. Heat emitted from the outer wall of the furnace body 110 can be confined as much as possible within the heat dissipation chamber 240 to prevent further outward diffusion. The gas drive unit 400 is fluidly connected to the heat dissipation chamber 240 to discharge high-temperature gas from the heat dissipation chamber 240 during operation. It is understood that the heat dissipation shroud 200 is made of high-temperature resistant and corrosion-resistant materials, such as fiberglass or steel plates lined with fiberglass. Preferably, in the length direction X, the heat dissipation shroud 200 covers at least 40% of the furnace body 110, more preferably at least 60% of the furnace body 110, even more preferably at least 80% of the furnace body 110, and most preferably completely covers the entire furnace body 110.

[0035] More specifically, the heat dissipation shroud 200 includes a top shroud portion 210 and a first side shroud portion 220 and a second side shroud portion 230 extending downward from the top shroud portion 210. The top shroud portion 210 is positioned above the furnace body 110 along the height direction Z, and an air outlet 211 is formed at the top of the top shroud portion 210. In particular, as shown in... Figure 2 As shown, the heat dissipation shroud 200 may include a plurality of air outlets 211 arranged sequentially along the length direction X, at least one of these air outlets 211, preferably each, being located above the high-temperature section 110b of the furnace body 110. It is understood that sufficient space is typically left between the top shroud 210 and the top wall 113 of the furnace body 110, and the sixth distance d6 between the top air outlet 211 of the top shroud 210 and the top of the furnace body 110 is typically between 1600 mm and 1950 mm, for example, approximately 1900 mm, to facilitate operator access for maintenance work. The first side shroud 220 and the second side shroud 230 preferably extend vertically downward from the bottom of the top shroud 210 and are positioned symmetrically opposite each other on both sides of the furnace body 110 along the width direction Y. In the illustrated embodiment, the first side cover 220 extends generally along the XZ plane and is opposite to the first side wall 111 of the furnace body 110 and the outer side wall 131 of the first mounting plate 130 along the width direction Y. The second side cover 230 extends generally along the XZ plane and is opposite to the second side wall 112 of the furnace body 110 and the outer side wall 141 of the second mounting plate 140 along the width direction Y. It is understood that the first side cover 220 and the first mounting plate 130, and therefore the first side wall 111, are separated by a gap allowing gas to pass through, and the second side cover 230 and the second mounting plate 140, and therefore the second side wall 112, are also separated by a gap allowing gas to pass through. In fact, the heat dissipation shroud 200 does not contact the furnace body 110 or the respective mounting plates, ensuring that as much heat as possible emitted from the side walls of the furnace body 110 can enter the heat dissipation chamber 240 upwards through these gaps and then be discharged outwards through the air outlet 211. The construction of the first mounting plate 130 and the second mounting plate 140 is not limiting, and they can have the same or different constructions for different temperature ranges of the furnace body 110. For example, for at least a portion of the furnace body 110 along the length direction X, the first mounting plate 130 and / or the second mounting plate 140 can form an internal cavity, and the top wall of the first mounting plate 130 and / or the second mounting plate 140 is preferably provided with one or more openings for guiding gas in the internal cavity to the heat dissipation chamber 240. More specifically, when heat is transferred from the side wall of the furnace body 110 to the first mounting plate 130 / second mounting plate 140, the gas in the internal cavity of the first mounting plate 130 / second mounting plate 140 expands at high temperature and can flow into the heat dissipation chamber 240 through the openings provided in the top wall of the first mounting plate 130 / second mounting plate 140. Furthermore, the top wall of the first mounting plate 130 / second mounting plate 140 is preferably inclined relative to the width direction Y, and the inclined top wall (e.g. Figure 3 The top wall 132 of the first mounting plate 130 can be made larger, thereby allowing for more openings to be distributed while ensuring airflow. It is understood that, in addition to the openings facing the heat dissipation chamber 240, the first mounting plate 130 / second mounting plate 140 may also include other openings for introducing cold air. These other openings for introducing cold air may be located at the bottom of the mounting plate or at its circumferential edge, thereby creating more efficient airflow within the internal cavity and improving heat dissipation efficiency. Furthermore, it is understood that the first mounting plate 130 and / or the second mounting plate 140 may not be provided for the cooling section 110c of the furnace body 110.

[0036] For this kiln equipment system, the first side cover 220 is configured to cover a portion of the first side wall 111 of the furnace body 110 along the height direction Z, and the second side cover 230 is configured to cover a portion of the second side wall 112 of the furnace body 110 along the height direction Z. For example, the bottom of each side cover 220 and the second side cover 230 is separated from the bottom 114 of the furnace body 110 by a fifth distance d5 along the height direction Z. It is understood that, in the illustrated embodiment, in order to allow the heating components to be disassembled and replaced along the width direction Y during the operation of the kiln equipment system, this fifth distance d5 needs to be determined such that the bottom of each side cover 220 and the second side cover 230 is positioned above each heating component along the height direction Z, particularly above the second heating component 180 that penetrates the top of the sintering chamber 120. This fifth distance d5 is typically between 1200 mm and 1600 mm. For example, when a second heating element 180 is provided, the fifth distance d5 can be approximately 1450 mm, corresponding to a furnace body 110 height of approximately 1550 mm. It is understood that if the first side cover 220 and the second side cover 230 are asymmetrically arranged, the fifth distance d5 needs to be determined such that the bottom of at least one of the side cover portions 220 and 230 is positioned above each heating element along the height direction Z.

[0037] In the illustrated embodiment, the maximum height of the heat sink 200 is preferably between 1500 mm and 2500 mm, and / or, the maximum width of the heat sink 200 is preferably between 1200 mm and 1800 mm. More specifically, in the illustrated embodiment, the first distance d1 along the height direction Z between the top of the top cover portion 210 of the heat sink 200 (i.e., the location of the air outlet 211 shown) and the bottom of each of the first side cover portions 220 and 230 is preferably between 2000 mm and 2500 mm, for example, approximately 2000 mm, and / or, the second distance d2 along the width direction Y between the first side cover portion 220 and the second side cover portion 230 is preferably between 1200 mm and 1800 mm, for example, approximately 1500 mm. It is understood that this second distance d2 may vary to some extent at different positions of the first side cover portion 220 and the second side cover portion 230 along the vertical direction. In fact, when the first side cover 220 and the second side cover 230 in the figure extend vertically, the second distance d2 is the distance along the width direction Y between the bottom 221 of the first side cover 220 and the bottom 231 of the second side cover 230.

[0038] In the illustrated embodiment, the third distance d3 along the width direction Y between the outer side wall 131 of the first hanging plate 130 and the first side cover 220, and between the outer side wall 141 of the second hanging plate 140 and the second side cover 230, is preferably between 50 mm and 120 mm, for example, about 100 mm, and / or, the fourth distance d4 along the width direction Y between the first side wall 111 and the first side cover 220, and between the second side wall 112 and the second side cover 230, is preferably between 90 mm and 180 mm, for example, about 150 mm. The "third distance d3" here is generally understood as the minimum distance along the width direction Y between the outer wall 131 of the first mounting plate 130 and the first side cover 220, and between the outer wall 141 of the second mounting plate 140 and the second side cover 230. The "fourth distance d4" is generally understood as the minimum distance along the width direction Y between the first side wall 111 and the first side cover 220, and between the second side wall 112 and the second side cover 230, because these minimum distances can determine the gas flow rate. It is understood that the locations with these minimum distances are not necessarily located at the bottom of the heat sink 200. In fact, when the first side cover 220 and the second side cover 230 extend vertically as shown in the figure, the third distance d3 is the distance along the width direction Y between the outer wall 131 of the first hanging plate 130 and the bottom 221 of the first side cover 220, and between the outer wall 141 of the second hanging plate 140 and the bottom 231 of the second side cover 230. The fourth distance d4 is the distance along the width direction Y between the first side wall 111 and the bottom 221 of the first side cover 220, and between the second side wall 112 and the bottom 231 of the second side cover 230. It can be understood that the first side cover 220 and the second side cover 230 can also be configured not to be parallel to each other. For example, according to one embodiment, the first side cover 220 can extend downward at an angle from the bottom of the top cover 210 in a manner that gradually moves away from the first side wall 111 and the first hanging plate 130, and the second side cover 230 can also extend downward at an angle from the bottom of the top cover 210 in a manner that gradually moves away from the second side wall 112 and the second hanging plate 140, so that the two sides of the heat sink 200 form a shape that expands downward slightly.

[0039] According to one implementation, such as Figure 3 As shown ( Figure 3Only the side adjacent to the first sidewall 111 is shown in the diagram; the other side may be symmetrically arranged. Auxiliary components, such as auxiliary inserts 250, can be provided on the first side cover 220 and / or the second side cover 230. The inserts 250 have a variable dimension along the width direction Y, thereby allowing the optimal third distance d3 (the third distance d3 is actually the distance between the insert 250 and the outer sidewall 131 of the first mounting plate 130 / the outer sidewall 141 of the second mounting plate 140) and the fourth distance d4 (the fourth distance d4 is actually the distance between the insert 250 and the first sidewall 111 / the second sidewall 112) to be determined by adjusting the Y-direction dimension of the insert 250. This ensures not only gas flow but also the disassembly of the first mounting plate 130 and the second mounting plate 140. After determining the third distance d3 and the fourth distance d4, the insert 250 can be fixedly connected to the first side cover 220 and / or the second side cover 230 by means such as welding, preferably fixedly connected to the bottom 231 of the first side cover 220 and / or the bottom 231 of the second side cover 230. It is understood that the number of auxiliary parts can be one or more, or the auxiliary parts can be arranged to be continuous in the length direction X; this invention does not limit this.

[0040] The heat sink 200 is preferably continuously distributed along the length direction X. Considering the difference in airflow, the first side cover 220 and / or the second side cover 230 can be configured to include a high-flow area and a low-flow area along the length direction X. Specifically, the distance between the high-flow area of ​​the first side cover 220 and the first side wall 111 is greater than the distance between the low-flow area of ​​the first side cover 220 and the first side wall 111, and the distance between the high-flow area of ​​the second side cover 230 and the second side wall 112 is greater than the distance between the low-flow area of ​​the second side cover 230 and the second side wall 112. In other words, a "high-flow area" refers to an area where the distance between the first side cover 220 or the second side cover 230 and the corresponding side wall is relatively large, and the airflow in this area is large; a "low-flow area" refers to an area where the distance between the first side cover 220 or the second side cover 230 and the corresponding side wall is relatively small, and the airflow in this area is small. In the length direction X, the low-throughput regions of the first side cover 220 and / or the second side cover 230 are located on at least one side of their high-throughput regions, for example, on both sides of their high-throughput regions. Preferably, the high-throughput region is located at the middle of the first side cover 220 in the length direction X, and the low-throughput region is located at the end of the first side cover 220 in the length direction X. The distance between the first side cover 220 and the side wall of the furnace body 110 can gradually decrease from the high-throughput region to the low-throughput region in the length direction X to form a smooth transition. And / or, the high-throughput region is located at the middle of the second side cover 230 in the length direction X, and the low-throughput region is located at the end of the second side cover 230 in the length direction X. The distance between the second side cover 230 and the side wall of the furnace body 110 can gradually decrease from the high-throughput region to the low-throughput region in the length direction X to form a smooth transition.

[0041] In other words, at the high-temperature section 110b along the length X of the furnace body 100, the first side cover 220 and / or the second side cover 230 preferably form a high-flow-rate region, and at the heating section 110a and / or cooling section 110c along the length X of the furnace body 100, the first side cover 220 and / or the second side cover 230 preferably form a low-flow-rate region. Therefore, the high-temperature section 110b of the furnace body 110 has a relatively high gas flow rate relative to the gaps on both sides of the heating section 110a and / or cooling section 110c of the furnace body 110 (i.e., the gap between the first side wall 111 / first hanging plate 130 and the first side cover 220 or the second side wall 112 / second hanging plate 140 and the second side cover 230), that is, the third distance d3 at the high-temperature section 110b of the furnace body 110 is preferably greater than the third distance d3 at the heating section 110a and / or cooling section 110c of the furnace body 110. According to one embodiment, at the high-temperature section 110b, the third distance d3 is preferably between 80mm and 120mm, for example, about 100mm, and at the heating section 110a and / or the cooling section 110c, the third distance d3 is preferably between 50mm and 100mm, for example, about 60mm. According to another embodiment, the difference between the maximum value of the third distance d3 and the minimum value of the third distance d3 is between 0 and 70mm, for example, about 40mm, with the maximum value of the third distance d3 located at the high-temperature section 110b of the furnace body 110, and the minimum value of the third distance d3 located at the heating section 110a and / or the cooling section 110c of the furnace body 110. It is understandable that, in order to facilitate the manufacturing of the heat sink 200, the overall width and height of the heat sink 200 (i.e., the first distance d1 and the second distance d2) can remain basically unchanged along the length direction X, while the width of the furnace body 110 may vary along the length direction X. Therefore, for different positions in the length direction X, the adjustment of the third distance d3 can be conveniently achieved by setting the aforementioned auxiliary components.

[0042] Furthermore, the heat dissipation device also includes at least one pipe 300, such as the first pipe 310 and the second pipe 320 shown. One end of the first pipe 310 is connected to the heat dissipation chamber 240 through one or more air outlets 211 of the heat dissipation shroud 200. At least one of the single air outlet 211 or multiple air outlets 211 is located in the aforementioned high-throughput area. A gas drive unit 400 is disposed between the other end of the first pipe 310 and the second pipe 320, and is connected to both the first pipe 310 and the second pipe 320. The gas drive unit 400 and the second pipe 320 are typically located outdoors. Therefore, when the gas drive unit 400 is in operation, the heat emitted from the first side wall 111, the second side wall 112, and the top wall 113 of the furnace body 110 can be confined as much as possible within the heat dissipation chamber 240, and the high-temperature gas in the heat dissipation chamber 240 can be discharged outdoors via the air outlets 211, the first pipe 310, and the second pipe 320.

[0043] The gas drive unit 400 can be, for example, a 4KW fan. During testing, with the kiln 100 not operating, the fan is first started, and then a wisp of smoke is ignited on the outside of the first side wall 111 or the second side wall 112 of the furnace body 110. It can be observed that gas is drawn into the heat dissipation chamber 240 through the bottom of the heat dissipation shroud 200 (i.e., through the gap between the first side wall 111 / first hanging plate 130 and the first side cover portion 220 or the second side wall 112 / second hanging plate 140 and the second side cover portion 230), and can be discharged outwards through the pipe 300. By using the heat dissipation device according to this invention, the indoor temperature of the kiln area can be effectively reduced by, for example, 5℃-10℃, which helps to avoid the adverse effects of the high-temperature environment of the kiln on the health and operation of the operators.

[0044] Furthermore, the operating speed of the gas drive unit 400 is preferably adjustable. For example, the rotational speed of the gas drive unit 400 can be set according to the season and indoor temperature. More specifically, for example, in the hot summer, the gas drive unit 400 is set to full speed operation; in the moderate temperatures of spring and autumn, the gas drive unit 400 is set to half speed operation; and in the cold winter, the gas drive unit 400 is set to low speed operation, or even not operated at all. Even when the gas drive unit 400 is operating at low speed, or even not operating at all, the heat sink 200 can still achieve, for example, a range of approximately 1000m due to the upward flow of hot air. 3 With an exhaust flow rate of / h, and the remaining heat diffused into the room, it can be used to raise the indoor temperature to the desired level and improve the working environment in winter.

However, it is understood that under the creative concept of this utility model, those skilled in the art can make various flexible changes and improvements to the above-disclosed concept, but all of them fall within the protection scope of this utility model.

[0046] The above description of the embodiments is exemplary and not restrictive, and the scope of protection of this utility model is determined by the claims.
