The paint spraying and baking room solves the problem that an existing paint spraying and baking room cannot effectively treat and guide out paint mist and threatens the health of workers, also solves the problem that flammable and explosive substances in the paint spraying and baking room are prone to accumulation and have potential safety hazards of explosion, and is compact in structure and high in practicability.

Description

Technical Field

[0001] The utility model relates to the technical field of spraying and baking varnish, in particular to a spraying and baking varnish room. Background Art

[0002] In the current industrial coating field, the performance and safety of the paint spraying and baking rooms, as key production equipment in the painting and baking processes, are crucial to ensuring the smooth progress of production operations, protecting the health of operators, and maintaining environmental safety. However, the paint spraying and baking rooms in the existing technology generally face two major problems that need to be solved during their design and operation.

[0003] First of all, during the painting process, the paint and thinner are atomized into a large number of fine paint mist particles by high-pressure spray equipment. These substances are atomized by high-pressure spray equipment during the painting process to form a large number of fine paint mist particles. These fine paint mist particles continue to accumulate in the paint spraying room, which not only seriously hinders the line of sight of the painting operation and reduces the operation efficiency, but is also likely to adhere to the surface of the object to be sprayed to form defects; what is more serious is that the paint mist that is not effectively treated may also escape to the outside through the exhaust system of the paint spraying room, causing pollution to the atmospheric environment and endangering public health; for operators who work in the paint spraying room for a long time, long-term exposure to an environment containing paint mist is undoubtedly a huge health hazard; harmful substances in paint mist, such as volatile organic compounds, heavy metal particles, etc., can enter the human body through the respiratory tract, causing irreversible damage to the respiratory system, nervous system, etc., and may even induce occupational diseases.

[0004] Secondly, when the workpiece is being sprayed and painted, the door of the spray paint room is closed, and the spray paint room forms a closed space. The paint and thinners used for spraying are mostly flammable and explosive substances. When the paint and thinner reach a certain concentration, they may mix with the air to form flammable gas. Once encountering a fire source, it is very easy to cause a fire or even an explosion, posing a huge threat to production equipment and personnel safety.

[0005] Therefore, in view of this, the inventor proposes a paint spraying and baking room to solve the above technical problems. Utility Model Content

[0006] One of the purposes of the utility model is to provide a paint spraying and baking room to solve the problem that the existing paint spraying and baking room cannot effectively process and guide the paint mist, posing a threat to the health of the workers. The second purpose is to easily accumulate flammable and explosive substances in the paint spraying and baking room, posing a potential explosion safety hazard.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0008] A paint spraying and baking room, comprising a room body, an air inlet device and an air outlet device; the air inlet device and the air outlet device are respectively arranged on one side of the room body;

[0009] A static pressure chamber, a spray chamber and an exhaust pit are formed inside the room body, and the static pressure chamber and the exhaust pit are respectively arranged on the upper and lower sides of the spray chamber;

[0011] The air outlet device includes an exhaust gas treatment structure, an air outlet driving component, a first pipe and a second pipe. The first pipe and the second pipe are respectively connected to the two ends of the exhaust gas treatment structure. The free end of the first pipe is connected to the exhaust pit, and the free end of the second pipe is connected to the air outlet driving component.

[0012] Further, the air intake unit includes a wind box and an air intake blower, the wind box is provided with a partition, the partition divides the interior of the wind box into a first cavity and a second cavity, the air intake blower is arranged in the second cavity, and the air intake blower can flow air from the first cavity into the second cavity;

[0013] The first cavity is communicated with the air inlet duct, and the second cavity is communicated with the air outlet duct.

[0014] Furthermore, at least one filter plate is disposed in the first cavity, and the filter plate is disposed obliquely.

[0015] According to the above technical solution, external air first enters the first cavity of the bellows through the air inlet duct, and the inclined filter plate is used to remove large particles of impurities and dust; the air inlet blower is arranged in the second cavity, and when the air inlet blower is started, it will generate negative pressure through rotation, and suck the air in the first cavity into the second cavity. In this process, the blower not only realizes the compression of the air, but also accelerates and pushes the air to the second cavity through its internal mechanism (such as impeller rotation). The second cavity is connected to the air outlet duct, and the air in the second space flows into the static pressure chamber. After a certain buffering and pressure equalization treatment, the air forms a stable airflow, which can ensure the uniform distribution of paint mist particles and reduce the splashing and deposition of paint mist.

[0016] Furthermore, the air intake unit also includes a heater, which is installed above the air intake blower and is used to heat the air.

[0017] According to the above technical solution, when the heater is started, the air entering the bellows is heated, and the heated air is then sent to the static pressure chamber and further distributed to the spray chamber to dry the workpiece.

[0018] Furthermore, the exhaust gas treatment structure includes a treatment box and a plurality of activated carbon frames, each of which is installed in the treatment box; activated carbon is placed inside each of the activated carbon frames.

[0019] According to the above technical scheme, during the painting and baking operation, waste gas containing paint mist particles, organic solvents and other harmful substances will be generated in the spray room and the exhaust pit. These waste gases are first collected and usually guided to the waste gas treatment structure; when the waste gas enters the treatment box, it will pass through each activated carbon frame. The activated carbon in the activated carbon frame has a strong adsorption capacity due to its porous structure and huge specific surface area. The harmful substances in the waste gas (such as organic solvents, paint mist particles, etc.) will contact the surface of the activated carbon and be adsorbed in its pores; after the adsorption treatment of the activated carbon frame, most of the harmful substances in the waste gas are removed, and the purified gas is then discharged through the outlet of the treatment box, reducing pollution to the environment.

[0020] Furthermore, thermal insulation walls are arranged around and on the top of the room.

[0021] Furthermore, the insulation wall comprises a plurality of fireproof insulation boards, and the fireproof insulation boards are assembled together to form the insulation wall;

[0022] The fireproof heat-insulating board comprises two color-coated boards and rock wool, and the rock wool is filled between the two color-coated boards.

[0023] According to the above technical scheme, the fireproof insulation board has excellent thermal insulation performance, which can effectively reduce the heat exchange inside and outside the spray paint room, reduce energy consumption and cost; at the same time, the design of the insulation wall also reduces the generation of thermal bridge effect and improves the thermal insulation performance of the entire room; rock wool is an inorganic non-combustible material with good fireproof performance. Therefore, the use of fireproof insulation board can greatly improve the fire safety of the spray paint room.

[0024] Furthermore, a diverter plate and a bottom plate grille are provided inside the room body, the diverter plate divides the room body into a static pressure chamber and a spraying room; the bottom plate grille divides the room body into a spraying room and an exhaust pit.

[0025] Wherein, pit filter cotton is arranged in the exhaust pit.

The temperature sensor is installed inside the room and is used to monitor the temperature inside the room; the temperature sensor and the heater are respectively connected to the controller, and the controller is connected to the control box.

[0027] According to the above technical solution, temperature sensors are installed inside the room to monitor the temperature inside the room in real time. These temperature sensors can capture tiny temperature changes and transmit these data to the controller. After receiving the data from the temperature sensor, the controller will immediately process and analyze it. It will compare the current temperature with the preset temperature range to determine whether the output power of the heater needs to be adjusted. If the current temperature is lower than the preset range, the controller will issue an instruction to start or increase the output power of the heater to increase the temperature inside the room. On the contrary, if the current temperature is too high, the controller will reduce the output power of the heater or turn off the heater to avoid overheating. During the whole process, the temperature sensor will continue to monitor the temperature changes and transmit new data to the controller. The controller will continuously adjust the output power of the heater according to the latest data to maintain the constant temperature inside the room.

[0028] Furthermore, a safety door is provided on the side wall of the room, and a glass observation window and a pressure lock are provided on the safety door.

[0029] According to the above technical scheme, the safety door is an important evacuation passage in the paint spraying and baking room in an emergency. Once a fire, equipment failure or other emergency occurs, the operator can quickly evacuate through the safety door to ensure personal safety; the glass observation window allows the operator to observe the operation status in the paint spraying and baking room in real time without opening the safety door, which helps to promptly discover and deal with problems in the spraying process, such as paint mist diffusion, temperature abnormalities, etc.; the pressure lock is a safety device. When the pressure in the paint spraying and baking room exceeds a certain value, the pressure lock can automatically open the safety door to release the pressure to prevent safety accidents such as explosions caused by excessive pressure, which provides additional safety protection for paint spraying and baking operations.

[0030] Beneficial effects of the utility model:

[0031] According to the above technical scheme, the utility model allows external air to enter the air inlet unit through the air inlet duct of the air inlet device, and the air inlet unit then brings the air into the air outlet duct, and the air enters the static pressure chamber through the air outlet duct. The design of the static pressure chamber enables the air to stabilize the pressure and be evenly distributed. After the air stabilizes the pressure in the static pressure chamber, the air enters the spraying room at a uniform speed and direction, providing a stable airflow environment for the paint spraying operation. When the operator is spraying paint on the workpiece, a stable airflow environment has been formed in the spraying room, and the airflow flows at a certain speed and direction to form a wind curtain surrounding the workpiece. Paint mist particles are confined to the area around the workpiece under the action of the wind curtain, and paint mist particles in the spraying room that are not completely blocked by the wind curtain and harmful gases generated during the painting process sink to the exhaust pit with the airflow, reducing the diffusion of paint mist and the area outside the surface of the workpiece that adheres to it. The paint mist during painting will not stay in the operator's breathing zone, avoiding a threat to the health of the staff, helping to improve the efficiency and quality of painting, and reducing pollution to the environment.

DETAILED DESCRIPTION

[0041] The following will describe the implementation of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the scope of protection of the present invention.

[0042] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0043] This embodiment provides a paint spraying and baking room, such as Figures 1 to 7 As shown, it includes a room body 1, an air inlet device 2 and an air outlet device 3; the air inlet device 2 and the air outlet device 3 are respectively arranged on one side of the room body 1; a diverter plate 14 and a bottom plate grille 15 are arranged inside the room body 1, and a plurality of air flow holes are opened on the diverter plate 14, and the diverter plate 14 divides the inside of the room body 1 into a static pressure chamber 11 and a spraying room 12; the bottom plate grille 15 divides the room body 1 into a spraying room 12 and an exhaust pit 13; wherein, the static pressure chamber 11 and the exhaust pit 13 are respectively arranged on the upper and lower sides of the spraying room 12.

[0044] The air inlet device 2 includes an air inlet unit 21, an air inlet duct 22 and an air outlet duct 23. The air inlet duct 22 and the air outlet duct 23 are respectively connected to the air inlet unit 21. The air inlet unit 21 can drive air to flow from the air inlet duct 22 to the air outlet duct 23. The free end of the air outlet duct 23 is connected to the static pressure chamber 11.

[0045] The paint mist treatment method of this embodiment is dry treatment; when it is implemented, the external air enters the air inlet unit 21 through the air inlet duct 22 of the air inlet device 2, and the air inlet unit 21 brings the air into the air outlet duct 23. The air enters the static pressure chamber 11 through the air outlet duct 23. The design of the static pressure chamber 11 allows the air to stabilize the pressure and distribute it evenly. After the air stabilizes the pressure in the static pressure chamber 11, it enters the spraying room 12 at a uniform speed and direction, providing a stable airflow environment for the painting operation; when the operator is painting the workpiece, a stable airflow environment has been formed in the spraying room 12. In a certain airflow environment, the airflow flows at a certain speed and direction to form an air curtain around the workpiece. The paint mist particles are confined to the area around the workpiece under the action of the air curtain. The paint mist particles in the spray room 12 that are not completely blocked by the air curtain and the harmful gases generated during the painting process sink to the exhaust pit 13 with the airflow, thereby reducing the diffusion of the paint mist and the adhesion to areas other than the workpiece surface. The paint mist during painting will not stay in the operator's breathing zone, thus avoiding a threat to the health of the staff, helping to improve the efficiency and quality of painting, and reducing pollution to the environment.

[0046] As a preferred embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the air intake unit 21 includes an air box 211 and an air intake blower 212. A partition 213 is provided in the air box 211. The partition 213 divides the interior of the air box 211 into a first cavity 214 and a second cavity 215. The air intake blower 212 is provided in the second cavity 215. The first cavity 214 is connected to the air intake duct 22, and the second cavity 215 is connected to the air outlet duct 23. The air intake blower 212 can drive air from the first cavity 214 to flow into the second cavity 215. At least one filter plate 216 is also provided in the first cavity 214, and the filter plate 216 is arranged obliquely.

[0047] According to the above technical scheme, external air first enters the first cavity 214 of the bellows 211 through the air inlet duct 22, and the inclined filter plate 216 is used to remove large particles of impurities and dust; the air inlet blower 212 is arranged in the second cavity 215. When the air inlet blower 212 is started, it will generate negative pressure through rotation, and suck the air in the first cavity 214 into the second cavity 215. In this process, the air inlet blower 212 not only realizes the compression of the air, but also accelerates and pushes the air to the second cavity 215 through its internal mechanism (such as impeller rotation). The second cavity 215 is connected to the air outlet duct 23, and the air in the second cavity 215 flows into the static pressure chamber 11. After a certain buffering and pressure equalization treatment, the air forms a stable airflow. The stable airflow can ensure the uniform distribution of paint mist particles and reduce the splashing and deposition of paint mist.

[0048] As a preferred embodiment, Figure 2 and Figure 4 As shown, the air inlet unit 21 also includes a heater 217. Preferably, the heater 217 is installed above the air inlet blower 212 to heat the air. When the heater 217 is started, the air entering the bellows 211 is heated, and the heated air is then sent to the static pressure chamber 11, and further distributed to the spray chamber 12 to dry the workpiece. Of course, it is understandable that the installation position of the heater 217 is not limited to the form of being installed above the air inlet blower 212, and can also be installed at a position below the air inlet blower 212, for heating the air and then driving the air flow by the air inlet blower 212, and the utility model does not limit this.

[0049] In a possible implementation, a heating device may be further provided on the inner top and inner side of the room body 1. The heating device may be an electric heating tube or a stainless steel heater to speed up the painting operation.

[0050] The air outlet device 3 includes an exhaust gas treatment structure 31, an air outlet drive member 32, a first pipe 33 and a second pipe 34. The first pipe 33 and the second pipe 34 are connected to both ends of the exhaust gas treatment structure 31, respectively. The free end (or end) of the first pipe 33 is connected to the exhaust pit 13, and the free end (or end) of the second pipe 34 is connected to the air outlet drive member 32. The air outlet drive member 32 is preferably an air outlet blower.

[0051] Considering that the room body 1 is relatively wide, starting from the uniform flow, the room body 1 adopts the foundation construction, and three exhaust pits 13 / or five blind passage foundation structures are set at the bottom of the room body 1, and floor grilles are laid on the exhaust pits 13 to facilitate exhaust; the floor grilles are made by the equipment factory using 30×5mm flat steel, and are all galvanized after processing, which ensures that the strength and rigidity of the floor grilles will not be deformed during long-term use. The length and width of each floor grille do not exceed 2×1.5m, which is convenient for disassembly and cleaning. The paint mud deposited on the floor grille is usually cleaned by chemical paint stripping, burning the grille, etc.; in a possible implementation, a water spraying device (not shown) can also be used, and the spray gun is extended into the room body 1 by extending the high-pressure pipe, and the floor grille is sprayed with a gun regularly. The mixed wastewater after spraying is diverted to the wastewater treatment system (not shown) for treatment, which can reduce the pollution of chemical emissions or incineration waste gas to the environment, and prevent the floor grille from deforming after burning, and make full use of the water spraying equipment to achieve the rational use of resources.

[0052] As a preferred embodiment, Figure 5 and Figure 6As shown, the waste gas treatment method is activated carbon adsorption; the waste gas treatment structure 31 includes a treatment box 311 and a plurality of activated carbon frames 312, each of which is installed in the treatment box 311; activated carbon is placed inside each activated carbon frame 312. During the painting and baking process, waste gas containing paint mist particles, organic solvents and other harmful substances will be generated in the spraying room 12 and the exhaust pit 13. After being guided to the treatment box 311, these waste gases will pass through each activated carbon frame 312. The activated carbon in the activated carbon frame 312 has a strong adsorption capacity due to its porous structure and huge specific surface area. The harmful substances in the waste gas (such as organic solvents, paint mist particles, etc.) will contact the surface of the activated carbon and be adsorbed in its pores; after the adsorption treatment of the activated carbon frame 312, the harmful substances in the waste gas are removed, and the purified gas is subsequently discharged under the action of the air outlet drive member 32, reducing the pollution to the environment. Among them, pit filter cotton is installed in the exhaust pit. The pit filter cotton can adhere to the paint that slides off during spraying, but the adsorption effect is reduced after long-term use and needs to be replaced in time.

[0053] As a preferred embodiment, Figure 1 , Figure 2 and Figure 7 As shown, the room body 1 is provided with an insulation wall 4 around and on the top, and the insulation wall 4 includes a plurality of fireproof insulation boards 41, and each fireproof insulation board 41 is assembled together to form the insulation wall 4; Figure 7 As shown, the fireproof insulation board 41 includes two color-coated boards 411 and rock wool 412, and the rock wool 412 is filled between the two color-coated boards 411. The rock wool 412 is made of natural basalt, which is processed by high-temperature melting and fiberization, and has good heat insulation, sound insulation, fire resistance and stability. The color-coated board 411 is the outer material of the rock wool 412. The color-coated board 411 not only has a beautiful appearance, but also has certain corrosion resistance and durability. The use of the fireproof insulation board 41 with excellent thermal insulation performance can effectively reduce the heat exchange inside and outside the spray paint room, reduce energy consumption and cost; at the same time, the design of the insulation wall 4 also reduces the generation of thermal bridge effect, and improves the insulation performance of the entire room body 1; at the same time, the rock wool 412 is also an inorganic non-combustible material with good fire resistance. Therefore, the use of the insulation wall 4 can greatly improve the fire safety of the spray paint room.

[0054] As a preferred embodiment, this embodiment also includes a temperature control system, which includes a temperature sensor 5, a controller and a control box. The temperature sensor 5 is installed inside the room 1 to monitor the temperature inside the room 1; the temperature sensor 5 and the heater 217 are respectively connected to the controller, and the controller is connected to the control box.

[0055] According to the above technical solution, the temperature sensor 5 is preferably a common temperature sensor 5 model such as PT100, NTC, etc., which can capture small temperature changes and transmit these data to the controller; the controller preferably includes an editable controller including a PID (proportional-integral-differential) control algorithm to ensure that the painting and baking operations are carried out under the best temperature conditions, thereby improving the quality and adhesion of the coating; after receiving the data from the temperature sensor 5, the controller will immediately process and analyze it, and it will compare the current temperature with the preset temperature range to determine whether it is necessary to adjust the output power of the heater 217; if the current temperature is lower than the preset range, the controller will issue an instruction to start or increase the output power of the heater 217 to increase the temperature in the room 1; on the contrary, if the current temperature is too high, the controller will reduce the output power of the heater 217 or turn off the heater 217 to avoid overheating; during the whole process, the temperature sensor 5 will continue to monitor the temperature changes and transmit new data to the controller. The controller continuously adjusts the output power of the heater 217 according to the latest data to maintain the constant temperature in the room 1.

[0056] As a preferred embodiment, a safety door 7 is provided on the side wall of the room 1, and a glass observation window and a pressure lock are provided on the safety door 7.

[0057] According to the above technical solution, the safety door 7 is an important evacuation passage in the paint spraying and baking room in an emergency. Once a fire, equipment failure or other emergency occurs, the operator can quickly evacuate through the safety door 7 to ensure personal safety; the glass observation window allows the operator to observe the operation status in the paint spraying and baking room in real time without opening the safety door 7, which helps to promptly discover and deal with problems in the spraying process, such as paint mist diffusion, temperature abnormalities, etc.; the pressure lock is a safety device. When the pressure in the paint spraying and baking room exceeds a certain value, the pressure lock can automatically open the safety door 7 to release the pressure to prevent safety accidents such as explosions caused by excessive pressure, which provides additional safety protection for paint spraying and baking operations.

[0058] like Figure 1 As shown, room 1 is a drawer-type spray paint room. The left end of room 1 is provided with a door, and the door size (width × height) is mm: 4400 × 5000; the door panel material of the door is made of EPS board to prevent the door from sagging; each door is connected by hinges to ensure flexible opening and closing. The door is edged with galvanized sheet, with a strong structure and not easy to deform after use; rubber sealing strips are used to seal the door around and between the doors, and a brush is used to seal the bottom of the door where it contacts the ground. After the door is closed, it is well sealed with the ground to ensure that the paint mist does not leak out during spray painting.

[0059] Furthermore, a pressure control system is also provided in the paint spraying and baking room, and the pressure lock needs to be connected to the pressure control system of the paint spraying and baking room to realize the automatic control of the pressure lock. When abnormal pressure is detected, the pressure lock will automatically respond and take corresponding safety measures to ensure the safety of the operation without manual intervention. It should be noted that the pressure control system is connected to the pressure lock to realize the automatic opening of the safety door 7 to release the pressure, which is a conventional technical means in the technical field and will not be elaborated here.

[0060] In a possible implementation, a monitoring room is further included. The control box is installed in the monitoring room. Monitoring equipment (such as a camera) is provided in the monitoring room for monitoring and controlling the situation inside the room 1.

[0061] In a possible implementation, a concentration alarm system, an anti-static device, a fire extinguisher, etc. can also be arranged inside the room 1. Among them, the concentration alarm system is connected to the controller, and the concentration alarm system is used to monitor the concentration of the gas in the room 1. When the concentration reaches the preset concentration, the concentration alarm system will sound an alarm; the fire extinguisher is used to extinguish the fire in an emergency; the anti-static device can be any device that can reduce or eliminate the generation and accumulation of static electricity and protect equipment and personnel from the harm of static electricity, and this example is not limited.

[0062] The utility model adopts the design of the air inlet device 2 and the static pressure chamber 11. After being filtered and heated, the external air enters the spray chamber 12 at a stable speed and direction, forming a wind curtain surrounding the workpiece. This stable airflow environment limits the diffusion of paint mist particles, so that they are mainly confined to the area around the workpiece. The paint mist particles in the spray chamber 12 that are not completely blocked by the wind curtain and the harmful gases generated during the painting process sink to the exhaust pit 13 with the airflow, effectively reducing the residence time and diffusion range of the paint mist in the spray chamber 12, and reducing the threat to the health of the workers; the exhaust gas treatment structure 31 in the air outlet device 3 includes a treatment box 311 and a plurality of activated carbon frames 312. Due to its porous structure and huge specific surface area, the activated carbon can adsorb harmful substances in the exhaust gas (such as organic solvents, paint mist particles, etc.), thereby purifying the exhaust gas. The treated exhaust gas is discharged under the action of the air outlet drive member 32, reducing the pollution to the environment; the insulation wall 4 is made of a fireproof insulation board 41 with excellent thermal insulation performance, which not only improves The thermal insulation performance of the room body 1 is also enhanced by the inorganic and non-combustible characteristics of the rock wool 412, which enhances the fire safety of the room body 1 and reduces the risk of fire caused by high temperature. The side wall of the room body 1 is provided with a safety door 7, and the safety door 7 is provided with a glass observation window and a pressure lock. The pressure lock is connected to the pressure control system of the paint spraying and baking room. When the pressure in the room body 1 is detected to be abnormal, the pressure lock will automatically open the safety door 7 to release the pressure to prevent safety accidents such as explosions caused by excessive pressure. The temperature control system achieves precise control of the temperature in the room body 1 through the temperature sensor 5, the controller and the control box, which helps to avoid the risk of fire caused by excessive temperature. At the same time, it also ensures that the painting and baking operations are carried out under the optimal temperature conditions, thereby improving the quality and adhesion of the coating; it solves the problem that the existing paint spraying and baking rooms cannot effectively process and export the paint mist, posing a threat to the health of the staff, and also solves the problem that flammable and explosive substances are easy to accumulate in the paint spraying and baking rooms, and there is a potential explosion safety hazard. The structure is compact and practical.

[0063] The above embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Any equivalent substitution or modification made by a person skilled in the art based on the present invention is within the protection scope of the present invention.
