A new type of ducted outdoor combined fresh air air conditioning unit

Abstract

This invention discloses a novel duct-type outdoor combined fresh air conditioning unit, belonging to the field of fresh air conditioning technology. It includes an integrated unit body and two filter plates. An installation plate is installed inside the integrated unit body, with an air intake port and an air outlet port. An indoor air conditioning unit is fixedly connected inside the integrated unit body, and one filter plate is secured within the integrated unit body. This invention utilizes a replacement device that drives a hanging ring and a locking plate to move synchronously, causing the corresponding filter plate to slide outward along a groove. Meanwhile, the tension on another steel cable is released, allowing the corresponding filter plate to slide into the integrated unit body under gravity. When the first motor reaches a preset position, the slid-in filter plate precisely engages with its mounting bracket, ensuring a stable installation. Simultaneously, the sealing gasket accurately embeds into the groove, forming a good seal. This allows for rapid filter plate replacement without stopping the machine, ensuring smooth airflow and improving equipment operating efficiency.

Description

Technical Field

[0001] This invention relates to the field of fresh air conditioning technology, specifically a novel duct-type outdoor combined fresh air conditioning unit. Background Technology

[0002] This air-conditioning unit integrates fresh air exchange, air purification, and temperature and humidity control. It not only circulates indoor air but also actively introduces fresh outdoor air and expels polluted air, reducing carbon dioxide concentration and improving air quality. The horizontal air-conditioning unit is suitable for ceiling, suspended ceiling, or outdoor installation. It integrates a filtration system, heat exchanger, fan, and cooling / heating system. Through total heat exchange and intelligent control, it improves energy efficiency and is suitable for residential, office, shopping mall, and other environments that require efficient ventilation and temperature control.

[0003] Existing technologies disclose several utility model patents in the field of air purification equipment. Among them, utility model patent application number CN117663257A provides a fresh air conditioning unit, which addresses the problem that current fresh air conditioning units typically use pre-filtering of air through a filter plate. This pre-filtering process leads to dust accumulation on the filter plate at the air intake over time, causing the filter holes to shrink and reducing airflow. Furthermore, the outdoor unit is usually mounted outdoors, especially on buildings, making outdoor cleaning extremely difficult. The invention includes a housing; the housing is a rectangular box-shaped structure with a horizontal end and a vertical end. An air conditioning air inlet is located on one side wall of the horizontal end of the housing. This invention achieves automatic cleaning during the filtration process, reducing the frequency of maintenance and cleaning, and maintaining the filtration effect of the drawn-in air for a longer period, thus improving the utilization rate of the equipment.

[0004] However, the existing new type of outdoor combined fresh air conditioning unit with ductwork has the following shortcomings:

[0005] 1. After a period of operation, the filter of the existing integrated fresh air conditioning unit is prone to clogging due to the accumulation of dust and impurities. The current replacement method is usually based on a fixed time period. However, when the air quality is poor or there are many suspended particles, the filter may clog in advance, affecting air circulation and equipment operating efficiency. In addition, the operation of the fresh air conditioning unit needs to be stopped during the replacement process, which increases maintenance time and operational complexity.

[0006] 2. When cleaning the filter plates, existing equipment usually only performs simple surface treatment, which is difficult to completely remove deep-seated dust, resulting in some pollutants remaining, affecting the air filtration effect, and thus reducing the purification efficiency and service life of the fresh air system. Summary of the Invention

[0007] The purpose of this invention is to provide a novel outdoor combined fresh air conditioning unit with ductwork, which addresses the problem of premature blockage caused by the accumulation of dust and impurities in external ductwork units, which cannot be addressed by the current fixed-cycle replacement method when air quality is poor.

[0008] To achieve the above objectives, the present invention provides the following technical solution: comprising an integrated unit body and two filter plates, characterized in that: an installation plate is installed inside the integrated unit body, an air intake is provided in the installation plate, an air outlet is provided inside the integrated unit body, an indoor air conditioning unit is fixedly connected inside the integrated unit body, one filter plate is clipped inside the integrated unit body, a replacement device is fixedly connected to the integrated unit body, two cleaning devices are fixedly connected inside the replacement device, and a spraying device is fixedly connected to the back of the integrated unit body;

[0013] Preferably, a dust baffle is fixedly connected to the upper surface of the all-in-one machine body, and a control panel is provided below the dust baffle, with the control panel fixedly connected to the top of the all-in-one machine body.

[0014] Preferably, a thermal wind speed sensor is fixedly connected inside the all-in-one machine body, and the thermal wind speed sensor is positioned corresponding to the filter plate.

[0015] Preferably, the cleaning device includes a base plate, a horizontal plate, and two rollers. The base plate is fixedly connected to the housing, and a vertical plate is fixedly connected to the base plate. Guide rails are symmetrically arranged inside the vertical plate. A second motor is fixedly connected to the horizontal plate. Four rotating shafts are rotatably connected to one side of the horizontal plate, and rollers are rotatably connected to the outside of the rotating shafts. The rollers are locked in the guide rails. The output end of the second motor is fixedly connected to one of the rotating shafts. Triangular plates are symmetrically installed on the upper surface of the horizontal plate. The same housing is fixedly connected to one side of the two triangular plates. Fixing blocks are symmetrically installed on one side of the housing. The same connecting rod is rotatably connected inside the two fixing blocks. A third motor is fixedly connected to the horizontal plate. One roller is fixedly connected to the output end of the third motor, and the other roller is sleeved on the connecting rod. The same belt is sleeved on both rollers, and a cleaning brush is sleeved on the connecting rod.

[0016] Preferably, the spraying device includes a receiving plate, which is fixedly connected to the back of the integrated machine body. Two limiting plates are fixedly connected to the receiving plate, and straps are fixedly connected inside the limiting plates. The same water storage tank is clamped inside the two straps. A water inlet is provided on the upper surface of the water storage tank, and two water pumps are fixedly connected to the upper surface of the water storage tank.

[0017] Preferably, the input end of the water pump is fixedly connected to a suction pipe, which passes through the water storage tank. The output end of the water pump is fitted with a flexible hose, and a sliding sleeve is fitted over the flexible hose. The sliding sleeve passes through the housing. The output end of the flexible hose passes through the housing. A nozzle passes through the flexible hose and is connected to the housing.

[0018] Preferably, a control button for triggering the second motor, the third motor, and the water pump is fixedly connected inside the positioning housing, and the control button is electrically connected to the second motor, the third motor, and the water pump.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. This invention, through the setting of a replacement device, allows the thermal anemometer to monitor the wind speed passing through the filter plate in real time. If the wind speed is lower than a preset value, the control panel starts the first motor through a preset program. The first motor drives the reciprocating screw to rotate freely within the frame. The reciprocating screw drives the threaded cap to move axially, and simultaneously drives the hook, fixing sleeve, and steel cable to move in coordination. During this process, one of the steel cables is pulled by a fixed pulley, driving the hanging ring and locking plate to move synchronously, thereby driving the corresponding filter plate to slide outward along the slide groove. The other steel cable is released from tension, allowing the corresponding filter plate to slide into the integrated machine body under gravity. When the first motor reaches the preset position, the slid-in filter plate is precisely locked into the holder, ensuring its stable installation. At the same time, the sealing gasket is accurately embedded in the slide groove, forming a good sealing state, thereby completing the rapid replacement of the filter plate without stopping the machine, ensuring smooth air circulation and improving the operating efficiency of the equipment.

[0021] 2. This invention, through the installation of a cleaning device, allows the positioning rod to insert into the positioning shell and trigger the control button when the filter plate moves to the designated cleaning position. The control panel then activates the second and third motors and the water pump. The second motor drives the rotating shaft to rotate, simultaneously causing the rollers to slide smoothly along the guide rail. The rollers' movement further drives the horizontal plate and cleaning brush to reciprocate vertically, ensuring the cleaning area covers the entire filter plate surface. During this process, the hose extends and retracts freely through the sliding sleeve to adapt to different cleaning areas. Simultaneously, the third motor drives the roller to rotate, which in turn drives the connecting rod to rotate within the fixed block via belt drive, synchronously driving the cleaning brush to rotate at high speed. This effectively removes dust and particulate contaminants adhering to the filter plate. The water pump draws water from the storage tank, delivers it to the nozzle via the hose, and thoroughly cleans the filter plate and cleaning brush through high-pressure spraying. The entire cleaning process can be preset with a cleaning time on the control panel. After the set time is reached, the system automatically stops the second and third motors and the water pump, achieving efficient and automated cleaning, improving the filter plate's purification effect, and reducing maintenance frequency.

[0022] 3. This invention, by setting up a ventilation duct, allows airflow to pass through the duct and enter the Y-shaped pipe when the air outlet is continuously supplying air. The airflow then exits from two outlets, one of which is directed towards the inside of the housing. The airflow acts on the surface of the cleaned filter plate, accelerating moisture evaporation and ensuring that the filter plate dries quickly, avoiding residual moisture that could affect the filtration effect. At the same time, a continuous airflow can be provided to the surface of the filter plate during the cleaning process to disperse the dust adhering to the filter plate, improving cleaning efficiency and reducing residual pollutants. By optimizing the airflow path, this device achieves rapid drying and dust removal while cleaning, further improving the service life of the filter plate and the overall purification effect of the fresh air system.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] This invention addresses the issue of external air traffic control units clogging due to the accumulation of dust and impurities, where the current fixed-cycle replacement method cannot cope with premature clogging during periods of poor air quality.

[0034] The filter plates of existing integrated fresh air conditioning units are prone to clogging due to the accumulation of dust and impurities. The current fixed-cycle replacement method is difficult to cope with poor air quality or high particulate matter, causing premature clogging, which affects air circulation and equipment operating efficiency. In addition, the machine needs to be shut down when replacing, which increases maintenance time and operational complexity.

[0035] This invention was developed to address the problems of the prior art by incorporating a replacement device 8. By monitoring the airflow speed of the filter plate in real time, the replacement program is automatically initiated when the airflow speed is insufficient, enabling rapid replacement of the filter plate without stopping the machine, thus ensuring air circulation and equipment efficiency.

[0036] Please see the appendix Figure 1 - Appendix Figure 8As shown, the present invention provides a technical solution: a novel ducted outdoor combined fresh air air conditioning unit, comprising an integrated unit body 1 and two filter plates 5. An installation plate 2 is installed inside the integrated unit body 1, and an air intake 3 is opened in the installation plate 2. An air outlet 14 is opened inside the integrated unit body 1. An indoor air conditioning unit 11 is fixedly connected inside the integrated unit body 1. One of the filter plates 5 is clipped inside the integrated unit body 1. A replacement device 8 is fixedly connected to the integrated unit body 1. Two cleaning devices 9 are fixedly connected inside the replacement device 8. A spraying device 10 is fixedly connected to the back of the integrated unit body 1.

[0037] Example 1, according to Figures 2-6 As shown, the replacement device 8 includes two steel cables 810, two hanging rings 811, two locking plates 812, and two fixed pulleys 807. The steel cables 810 are wound around the fixed pulleys 807, and the locking plates 812 are fixedly connected to the filter plates 5. When one of the steel cables 810 is pulled, the corresponding filter plate 5 moves along a set path. The two steel cables 810 are respectively wound around the fixed pulleys 807 and connected to the hooks 808, the fixing sleeves 809, the hanging rings 811, etc. When the first motor 803 drives the reciprocating screw 804 to move the threaded cap 805, the hooks 808 are linked, one steel cable 810 is pulled and moves the filter plate 5 outward, and the other steel cable 810 relaxes synchronously with the mechanical movement, so as to realize the opposite movement and synchronous release of the corresponding filter plate 5, and cross-replace the filter plate 5.

[0038] The replacement device 8 also includes a housing 801, four positioning shells 813, and four positioning rods 815. The housing 801 is rectangular or a regular box shape matching the equipment installation space. The housing 801 is fixedly connected to the integrated machine body 1. A frame 802 is bolted inside the housing 801. A first motor 803 is fixedly connected to one side of the frame 802. A reciprocating screw 804 is fixedly connected to the output end of the first motor 803. The journals at both ends of the reciprocating screw 804 mate with the inner rings of bearings, allowing it to rotatably connect inside the frame 802. A threaded cap 805 is fitted onto the reciprocating screw 804 (by manually or with assembly equipment, the internal thread of the threaded cap 805 is screwed into the screw along the screw axis to engage with the external thread of the screw, thus completing the fitting). During rotation, the rotational motion of the lead screw is converted into the linear reciprocating motion of the threaded cap 805 by utilizing the threaded engagement. A connecting plate 806 is symmetrically installed on the outside of the frame 802, with the symmetry reference being the central axis of the frame 802. A fixed pulley 807 is fixedly connected inside the connecting plate 806. Two hooks 808 are fixedly connected below the threaded cap 805, and a fixing sleeve 809 is hung inside each hook 808. Two steel cables 810 are respectively fixedly connected to the corresponding fixing sleeves 809. A hanging ring 811 is fixedly connected to the lower end of the steel cable 810 and is fitted inside the locking plate 812. Two positioning shells 813 are fixedly connected to the upper surface of the filter plate 5 inside the housing 801, and two other positioning shells 813 are fixedly connected to the upper surface of the filter plate 5 inside the integrated machine body 1. Positioning rods 815 are fixedly connected inside the housing 801 (bolts are passed through the mounting holes of the positioning rods 815 and screwed into the threaded holes of the housing 801, achieving fastening through thread engagement). Two positioning rods 815 are engaged within two of the positioning shells 813. Two water outlet pipes are connected through the front of the housing 801, and the engagement of the positioning rods 815 with the positioning shells 813 is coordinated. When the filter plate 5 is replaced and slides into the cleaning area of ​​the housing 801, the positioning rod 815 is precisely inserted into the corresponding positioning shell 813, triggering the control button inside the positioning shell 813. This triggers the control buttons of the second motor 905, the third motor 912, and the water pump 1006, thereby automatically starting the cleaning device 9 and the spraying device 10 to clean the filter plate 5. A ventilation vent is provided on one side of the housing 801. Two mounting brackets 4 are fixedly connected inside the integrated machine body 1, and their groove dimensions match the thickness and width of the filter plate 5 to ensure the filter plate 5... It can be precisely embedded and stably clamped. One of the filter plates 5 is clamped in one of the brackets 4. The air conditioner indoor unit 11 is installed inside the integrated unit body 1. The air outlet 14 and the housing 801 are fixedly connected by the same ventilation pipe 12, and the ventilation pipe 12 runs through the housing 801. The ventilation pipe 12 is set as a Y-shaped pipe for gas diversion. The ventilation pipe 12 has a Y-shaped structure, that is, the main pipeline splits into two branches in the middle, forming a "Y" shape. One end of the main pipeline is connected to the air outlet 14 of the integrated unit body 1, and the two branches extend into the housing 801 respectively.A "one inlet, two outlets" airflow channel is formed. The bifurcation angle and branch length need to be adapted to the installation position of the air outlet 14 and the housing 801 to ensure efficient airflow diversion. Two sliding grooves 15 are opened on the contact surfaces of the integrated unit body 1 and the housing 801 (the surfaces that touch each other when the integrated unit body 1 and the housing 801 are connected, which are the "channel contact surfaces" for the sliding replacement of the filter plate 5). The filter plate 5 is slidably connected in the sliding grooves 15. Sealing gaskets 16 are fitted on the upper and lower surfaces of the filter plate 5. Two of the sealing gaskets 16 are stuck in the sliding grooves 15. After the sealing gaskets 16 are stuck in the sliding grooves 15, they can fill the gap between the filter plate 5 and the sliding grooves 15. A gap is provided to prevent unfiltered air from directly entering the integrated unit body 1, ensuring that all airflow must pass through the filter plate 5 before being discharged from the air outlet 14, thus guaranteeing the fresh air purification effect. A dust baffle 13 is fixedly connected to the upper surface of the integrated unit body 1. Its surface has a plate-like structure to block dust and debris and protect the top components of the equipment. A control panel 7 is located below the dust baffle 13 and is fixedly connected to the top of the integrated unit body 1. A thermal wind speed sensor 6 is fixedly connected inside the integrated unit body 1. The thermal wind speed sensor 6 is positioned corresponding to the filter plate 5 and is used to monitor the wind speed changes after passing through the filter plate 5 in real time.

[0039] The overall effect of Embodiment 1 is as follows: The thermal anemometer 6 uses the XZ4150D model, which enables the filtration system to dynamically adjust according to the actual operating conditions, avoiding the problem of premature or delayed replacement that may be caused by the traditional timed replacement method, thus improving the utilization efficiency of the filter plate 5. At the same time, after the sealing gasket 16 is inserted into the slide groove 15, it ensures the sealing during the replacement process, avoiding air leakage or airflow loss caused by replacement, and ensuring the stable operation of the fresh air system. In addition, the entire replacement process does not require manual intervention, which greatly reduces maintenance costs, and allows the equipment to complete the replacement of the filter plate 5 while in operation, avoiding the impact of air circulation due to shutdown replacement, and ensuring the continuous optimization of indoor air quality.

[0040] Example 2, according to Figures 4-5As shown, the cleaning device 9 includes a base plate 901, a horizontal plate 904, and two rollers 913. The base plate 901 is fixedly connected inside the housing 801. A vertical plate 902 is fixedly connected to the base plate 901. Guide rails 903 are symmetrically arranged inside the vertical plate 902 (symmetrical with respect to the central axis of the vertical plate 902). A second motor 905 is fixedly connected inside the horizontal plate 904. Four rotating shafts 906 are rotatably connected to one side of the horizontal plate 904. Rollers 907 are rotatably connected to the outside of the rotating shafts 906. The rollers 907 are locked inside the guide rails 903. The output end of the second motor 905 is fixedly connected to one of the rotating shafts. Outside of 906, triangular plates 908 are symmetrically mounted on the upper surface of the horizontal plate 904. A housing 909 is fixedly connected to one side of each of the two triangular plates 908. A fixing block 910 is symmetrically mounted on one side of the housing 909. A connecting rod 911 is rotatably connected within each of the two fixing blocks 910. A third motor 912 is fixedly connected to the horizontal plate 904. One of the rollers 913 is fixedly connected to the output end of the third motor, and the other roller 913 is sleeved on the connecting rod 911. A belt 914 is fitted over both rollers 913. A cleaning brush 915 is fitted over the connecting rod 911. The spraying device 10 includes a receiving plate 1001, which is fixedly connected to the back of the integrated machine body 1. Two limiting plates 1002 are fixedly connected to the receiving plate 1001. Straps 1003 are fixedly connected inside the limiting plates 1002. The same water storage tank 1004 is held in the two straps 1003. A water inlet 1005 is provided on the upper surface of the water storage tank 1004. Two water pumps 1006 are fixedly connected to the upper surface of the water storage tank 1004. A suction pipe is fixedly connected to the input end of the water pump 1006 and passes through the water storage tank 1004. The output end of 006 is fitted with a flexible hose 1007, and the flexible hose 1007 is fitted with a sliding sleeve 1008. The sliding sleeve 1008 is connected through the housing 801. The output end of the flexible hose 1007 is connected through the housing 909. A nozzle 1009 is connected through the flexible hose 1007. The nozzle 1009 is connected through the housing 909. A control button for triggering the second motor 905, the third motor 912 and the water pump 1006 is fixedly connected inside the positioning housing 813. The control button is electrically connected to the second motor 905, the third motor 912 and the water pump 1006.

[0041] The overall effect of Embodiment 2 is as follows: By setting up the cleaning device 9 and the spraying device 10, automatic cleaning of the filter plate 5 is achieved, making the cleaning process more thorough and effectively reducing the problem of increased wind resistance caused by dust accumulation on the surface of the filter plate 5, thereby improving air filtration efficiency. A cooperative structure of hose 1007 and sliding sleeve 1008 is adopted. The sliding sleeve 1008 is connected through the housing 801, and the hose 1007 is sleeved inside the sliding sleeve 1008. The sliding sleeve 1008 provides stable guidance for the hose 1007, ensuring that the hose 1007 maintains a relatively stable position and direction during the operation of the cleaning device 9. The horizontal plate 904 in the cleaning device 9 drives the cleaning brush 915 to reciprocate in the vertical direction. The sliding sleeve 1008 constrains the hose 1007, preventing it from swaying or twisting due to the movement of the cross plate 904. This ensures that the water flow can be stably delivered from the hose 1007 to the nozzle 1009, avoiding water concentration in localized areas due to hose misalignment. This ensures that the water flow is evenly sprayed on the surface of the filter plate 5, while also preventing excessive water concentration from affecting the structure of the filter plate 5. In addition, the optimized design of the ventilation pipe 12 not only accelerates the drying of the filter plate 5 after cleaning, preventing the growth of bacteria or mold due to moisture, but also uses high-speed airflow to blow away residual dust, improving the overall cleaning effect, extending the service life of the filter plate 5, thereby reducing maintenance frequency and improving the reliability and durability of equipment operation.

[0042] The working principle of the entire device is as follows: The thermal wind speed sensor 6 monitors the wind speed change of the filter plate 5 in real time. When the wind speed is lower than the preset threshold, the control panel 7 triggers the first motor 803 to start through the command, which drives the reciprocating screw 804 to rotate in the frame 802. The threaded cap 805 moves along the screw and synchronously drives the hook 808, the fixing sleeve 809 and the steel cable 810 to operate in coordination. One of the steel cables 810 is pulled by the fixed pulley 807, which makes the hanging ring 811 and the locking plate 812 connected to it move synchronously, thereby driving the corresponding filter plate 5 to slide outward along the slide groove 15. The other steel cable 810 is released due to the tension, and its corresponding filter plate 5 slides into the integrated machine body 1 under the action of gravity. When the first motor 803 runs to the preset position, the filter plate 5 on the side that has slid in is accurately locked into the card seat 4. At the same time, the sealing gasket 16 is embedded in the slide groove 15 to ensure the airtightness after replacement, and completes the automatic replacement process of the filter plate 5.

[0043] After filter plate 5 is replaced and enters the cleaning area of ​​housing 801, in the new type of outdoor combined fresh air air conditioning unit with ductwork, positioning rod 815 is inserted into positioning housing 813 to trigger the control button, relying on mechanical contact and electrical control connection. Positioning housing 813 contains a control button, which is electrically connected to the second motor 905, the third motor 912, and the water pump 1006. When filter plate 5 is replaced and enters the cleaning area of ​​housing 801, positioning rod 815 is inserted into positioning housing 813, and the positioning rod 815 touches the control button after insertion. From a mechanical perspective, the insertion of the positioning rod 815 into the positioning housing 813 is like inserting a key into a lock. As a triggering component, when the positioning rod 815 reaches the button's position inside the positioning housing 813, it presses the button, activating its internal circuitry and triggering the control button. The control panel 7 then activates the second motor 905, the third motor 912, and the water pump 1006. The second motor 905 drives the rotating shaft 906 to rotate, simultaneously causing the roller 907 to slide smoothly along the guide rail 903, pushing the horizontal plate 904 and the cleaning brush 915 to reciprocate vertically, ensuring the cleaning area covers the entire surface of the filter plate 5. During this process, the hose 1007 passes through… The sliding sleeve 1008 can extend and retract freely to adapt to different cleaning areas. At the same time, the third motor 912 drives the roller 913 to rotate, and the belt 914 drives the connecting rod 911 to rotate in the fixed block 910. Simultaneously, it drives the cleaning brush 915 to rotate at high speed, so that the attached dust and particulate pollutants are removed from the filter plate 5. The water pump 1006 draws water from the water tank 1004 and delivers it to the nozzle 1009 through the hose 1007. The high-pressure jet cleans the filter plate 5 and the cleaning brush 915 to ensure that the dirt is completely removed. The entire cleaning process is set by the control panel 7. After the set value is reached, the relevant equipment will automatically stop, and the automatic cleaning of the filter plate 5 will be completed.

[0044] Ventilation duct 12 connects to air outlet 14. High-speed airflow enters the Y-shaped duct and exits from two outlets. The airflow from one outlet enters the housing 801 to dry the cleaned filter plate 5, accelerating moisture evaporation and preventing moisture from affecting the performance of the filter plate 5. At the same time, it can provide continuous blowing to the surface of the filter plate 5 during the cleaning process, using airflow to carry away the attached dust particles and optimize the cleaning effect. The entire system achieves efficient maintenance of the filter plate 5 through automatic replacement, automatic cleaning, and airflow drying, ensuring the long-term stable operation of the fresh air system.

[0045] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
