Description

Technical Field

[0001] The utility model relates to the technical field of experimental research on gas flow patterns, and specifically to a gas flow pattern activity device. Background Art

[0002] An atomizer is a device used to convert a liquid into mist-like particles and is commonly used in medical, industrial, and experimental research fields. The atomizer disperses liquid molecules into tiny particles through high-frequency vibration or heating to form a suspended mist.

[0003] Among them, the atomizer has a wide range of applications in experimental research on gas flow activities. The atomizer can convert a liquid into tiny mist-like particles, and these particles can simulate the movement of various gas particles in the gas flow. In gas flow activity experiments, experimenters can use the atomizer to generate mist-like particles and then observe the movement trajectories, diffusion laws, and interactions with other substances of these particles under different gas flow conditions.

[0004] For example, in aerodynamic research, an atomizer can be used to generate fine particles to simulate the particles in the air, so as to observe the flow conditions of the gas flow under different conditions and the transport and deposition laws of the particles in the flow field. This is of great significance for understanding air flow, air pollutant transport, and air quality improvement.

[0005] In addition, in the built environment, the atomizer can also be used to simulate the indoor air flow situation, help design a more effective ventilation system, improve indoor air quality, and study the distribution and diffusion laws of indoor particulate matter.

[0006] The existing atomizer supporting equipment on the market is not perfect enough. The water tank for providing atomization raw materials generally uses a single large-capacity water tank or is equipped with a small spare water tank. The number of water tanks does not meet the diversification of experimental research. When using multiple solution reagents for testing, experimenters need to frequently clean the water tank and replace the solution to conduct tests on different solution reagents, which is not convenient for experimenters to use multiple solution reagents simultaneously, reduces the efficiency of the experimental research process, and prolongs the experimental research cycle.

[0007] In view of the above deficiencies, we need to develop a gas flow pattern activity device to meet the usage needs of the majority of users. Content of the Utility Model

[0008] In view of the problems mentioned above that the existing atomizer supporting equipment is not perfect enough, it is not convenient for experimenters to use multiple solution reagents simultaneously, and the efficiency of the experimental research process is reduced, the technical solution adopted by the utility model to solve its technical problems is:

[0009] A gas flow pattern activity device includes a main body, a flexible air pipe, and a flow pattern air pipe. One end of the flow pattern air pipe is connected to the main body through the flexible air pipe. The flow pattern air pipe is provided with a plurality of flow pattern air holes for discharging gas. The main body is provided with a liquid storage tank, a filter, and an atomizing device communicating with the filter. The liquid storage tank is provided with at least two independent liquid storage chambers, and each liquid storage chamber is respectively connected to the filter. The atomizing device includes an atomizer for atomizing liquid. The output end of the atomizer is connected to the flexible air pipe. The filter transports the liquid in the liquid storage tank to the atomizing device, and after being processed by the atomizer to form an aerosol, it is output to the flow pattern air pipe and discharged from the flow pattern air holes.

[0010] Further, the flow pattern air pipe is a hollow cylindrical tube structure. The cylindrical tube structure is provided with a flow pattern air cavity for gas to flow through. The flow pattern air holes are arranged on the outside of the cylindrical tube structure and communicate with the flow pattern air cavity.

[0011] Further, the flow pattern air holes are linearly arranged along the length direction of the flow pattern air pipe, and the exhaust direction of the flow pattern air holes is towards the radial direction of the cylindrical tube structure.

[0013] Further, the flow pattern air pipe is provided with a pipe end cover for easy cleaning. The pipe end cover is detachably connected to the end of the flow pattern air pipe away from the flexible air pipe.

[0014] Further, the atomizing device includes a mixer for mixing liquids. The mixer is connected between the atomizer and the filter.

[0015] Further, a one-way solenoid valve for controlling on-off is independently provided between each liquid storage chamber and the filter.

[0016] Further, the outside of the main body is provided with a handle for easy gripping, a hanging hook for storing pipelines, and a plurality of steerable and slidable pulleys. The pulleys are symmetrically arranged on both sides of the bottom of the main body with the center of the main body as the center.

[0017] Further, the flexible air pipe and / or the flow pattern air pipe are made of a transparent material.

[0018] Further, the flow pattern air pipe is provided with a light source for enhancing the display of the gas flow pattern trajectory. The light source can be arranged inside and / or outside the flow pattern air pipe.

Multiple independently separated liquid storage chambers are arranged in the liquid storage tank. Different liquid storage chambers are respectively connected to the atomizing device through filters to meet the tests using multiple solution reagents. Experimental personnel can load multiple solution reagents into different liquid storage chambers at one time, reducing the frequency of replacing solution reagents and cleaning the water tank, reducing the replacement time.

[0028] The following will describe the embodiments of the utility model in detail with reference to the drawings.

[0029] As shown in Figures 1 to 5As shown in the figure, a gas flow pattern activity device includes a main unit 1, a flexible hose 2, and a flow pattern air pipe 3. One end of the flow pattern air pipe 3 is connected to the main unit 1 through the flexible hose 2. The flow pattern air pipe 3 is provided with a plurality of flow pattern air holes 31 for discharging gas. The main unit 1 is provided with a liquid storage tank 11, a filter 12, and an atomization device 13 communicating with the filter 12. The liquid storage tank 11 is provided with at least two independent liquid storage chambers 111, and each liquid storage chamber 111 is respectively connected to the filter 12. The atomization device 13 includes an atomizer 131 for atomizing liquid. The output end of the atomizer 131 is connected to the flexible hose 2. The filter 12 transports the liquid in the liquid storage tank 11 to the atomization device 13. After being processed by the atomizer 131 to form an aerosol, it is output to the flow pattern air pipe 3 and discharged from the flow pattern air holes 31.

[0030] Specifically, in some embodiments, the main unit 1 is the chassis body of the gas flow pattern activity device for storing experimental liquids and providing an atomization function. The internal equipment and water circuit structure are wrapped by a thin metal outer shell. The top of the main unit 1 is provided with a main unit connection pipe orifice for the flexible hose 2 to extend into. The main unit connection pipe orifice and the flexible hose 2 are tightly connected with airtightness and watertightness. The front end of the main unit 1 is provided with a control panel 14 for experimental personnel to operate. The control panel 14 is provided with a controller 141 for controlling the operation of the internal equipment and an electronic screen for displaying equipment parameters. The liquid storage tank 11 is provided with a weight sensor for real-time detection of the liquid storage capacity. The controller 141 is electrically connected to the atomization device 13 and the liquid storage tank 11, so that experimental personnel can control the atomization device 13 externally and can also know the remaining liquid storage volume in the liquid storage chamber 111 through the electronic screen.

[0031] The liquid storage tank 11 is a box structure of the gas flow pattern activity device for centrally storing experimental liquids. At least two independent liquid storage chambers 111 are provided inside the liquid storage tank 11. The liquid storage chambers 111 are used for storing experimental liquids. Experimental personnel can respectively pour different experimental liquids into multiple different liquid storage chambers 111 before operation. Each liquid storage chamber 111 can be connected to the filter 12 through an independent water pipe. The filter 12 can filter out larger particles in the experimental liquid to prevent blockage of the atomizer 131 and the water circuit system. After the experimental liquid flows out of the liquid storage chamber 111 and is filtered by the filter 12, it is transported by the filter 12 to the atomization device 13 for processing.

[0032] The atomizing device 13 is a gas flow type movable device for atomizing experimental liquids. Optionally, the atomizer 131 can be an atomizing device with different working principles such as a mechanical atomizer, an ultrasonic atomizer, a heating atomizer, or a pressure atomizer. Preferably, the atomizer 131 uses an ultrasonic atomizer to achieve the atomizing effect. The ultrasonic atomizer utilizes the principle of ultrasonic vibration to disperse the liquid into tiny particles. The liquid is placed in an ultrasonic vibrator, and the ultrasonic vibration disperses the liquid molecules on the liquid surface into microparticles, forming a mist. The experimental liquid forms microparticles of 1 - 10 μm through the ultrasonic atomizer. These microparticles, as tracer particles, can exist in the air for a long time and can be used to reflect the airflow direction, facilitating the observation by experimental personnel. After the experimental liquid is atomized by the atomizer 131 to form an aerosol, it is output to the flow type air pipe 3 through the flexible hose 2;

[0033] The flexible hose 2 is a foldable and telescopic plastic flexible hose, made of plastic with good corrosion resistance and chemical resistance, facilitating telescopic storage and extension to a larger applicable range. The two ends of the flexible hose 2 are respectively connected to the main body 1 and the flow type air pipe 3. The aerosol output by the atomizer 131 can flow through the flexible hose 2 to the flow type air pipe 3. The flow type air pipe 3 is an output tool for experimental personnel to hold and observe the atomized gas flow type. A plurality of flow type air holes 31 for discharging the aerosol are provided on the outer side of the flow type air pipe 3. The flow type air holes 31 protrude on the outer surface of the flow type air pipe 3 and are designed to be hollow to communicate with the inside of the flow type air pipe 3. The aerosol output by the atomizer 131 can be evenly output to the outside through the plurality of flow type air holes 31, forming a fog-like gas existing in the air for experimental personnel to observe.

[0034] As Figure 3 and Figure 4 shown, the flow type air pipe 3 has a hollow cylindrical tube structure. The cylindrical tube structure is provided with a flow type air cavity 32 for gas flow, and the flow type air holes 31 are provided on the outer side of the cylindrical tube structure and communicate with the flow type air cavity 32.

[0035] Specifically, in some embodiments, the flow type air pipe 3 has a hollow thin-walled cylindrical tube structure. The tube opening of the flow type air pipe 3 communicating with the outside is connected to the flexible hose 2. The inside of the cylindrical tube structure is provided with a flow type air cavity 32 for gas flow. The flexible hose 2 transports the aerosol output by the atomizer 131 to the flow type air cavity 32 and then evenly outputs it to the outside through the flow type air holes 31. The thin-walled cylindrical tube structure of the flow type air pipe 3 can be made of metal, plastic, or glass, and can be of an integrally formed structure to maintain the overall airtightness and watertightness. Compared with the split-type formed structure, it can effectively avoid aerosol leakage. A detachable elastic sealing ring can also be used at the connection of the flow type air pipe 3 in contact with the flexible hose 2 as a sealing tool to maintain airtightness and watertightness.

[0036] As Figures 1 to 4As shown, the flow pattern air holes 31 are arranged in a straight line along the length direction of the flow pattern air tube 3, and the exhaust direction of the flow pattern air holes 31 faces the radial direction of the bobbin structure.

[0037] Specifically, in some embodiments, the flow pattern air holes 31 are arranged at uniform intervals in a straight line along the length direction of the flow pattern air tube 3, which can concentrate the exhaust direction of the flow pattern air holes 31 on the same side of the flow pattern air tube 3, and can also maintain the uniform dispersion when the aerosol is discharged. When the exhaust volume is relatively small, the aerosol can be concentrated on the same side as much as possible to form a gas flow pattern movement trajectory that is convenient for observation. The structure of concentrated exhaust also facilitates the experimenter to hold and operate the flow pattern air tube 3, making the range and contour of the aerosol formation easier to control, and is suitable for experimental sites with less experimental liquid dosage or smaller space.

[0038] As Figure 5 shown, the flow pattern air holes 31 are arranged in a staggered manner along the length direction of the flow pattern air tube 3 and are arranged at intervals around the center circumference of the bobbin structure.

[0039] Specifically, in some embodiments, the flow pattern air holes 31 are arranged at staggered intervals along the length direction of the flow pattern air tube 3, and the flow pattern air holes 31 are arranged at intervals around the central axis of the bobbin structure. With such a design, the exhaust direction of the flow pattern air holes 31 can be distributed in the radial range of the bobbin structure. When the exhaust volume is relatively large, the aerosol can be evenly dispersed from different directions as much as possible to form a larger and denser aerosol cluster, and the efficiency of outputting the aerosol is faster, and the observable aerosol range is wider, which is suitable for experimental sites with more experimental liquid dosage or larger space.

[0040] As Figures 1 to 5 shown, the flow pattern air tube 3 is provided with a tube end cover 33 that is convenient for cleaning, and the tube end cover 33 is detachably connected to one end of the flow pattern air tube 3 away from the flexible air tube 2.

[0041] Specifically, in some embodiments, after the flow-type trachea 3 has been used for a long time, it may be necessary to clean the residual solution inside. When the aerosol output by the atomizer 131 passes through the flexible trachea 2 and the flow-type trachea 3, a relatively large amount of residual solution will adhere to the inner side wall thereof. There may be mutual reactions and influences between different experimental liquids. If not cleaned in time, it will affect the results of subsequent experiments. Therefore, a tube end cap 33 is detachably connected to one end of the flow-type trachea 3 away from the flexible trachea 2 and is installed on the flow-type trachea 3 by means of clamping, screwing, sliding, etc. The surface of the tube end cap 33 in contact with the flow-type trachea 3 can be made of an elastic material with airtightness and watertightness, so that the installation and disassembly between the tube end cap 33 and the flow-type trachea 3 can also ensure the overall airtightness and watertightness, effectively avoiding aerosol leakage and ensuring the accuracy of experimental results. When in use, the tube end cap 33 can be removed to flush the flow-type trachea 3. The operation is simple, convenient and fast, effectively shortening the experimental time and simplifying the cleaning process.

[0042] As Figure 3 shown, the atomization device 13 includes a mixer for mixing liquids, and the mixer is connected between the atomizer 131 and the filter 12.

[0043] Specifically, in some embodiments, the mixer is a small device for fully mixing experimental liquids from different liquid storage chambers 111. The mixer is arranged between the atomizer 131 and the filter 12 and is electrically connected to the controller 141. Inside the mixer, there is a rotatable stirring structure, a stirring inner cavity for accommodating the stirring structure, and a stirring motor for driving the stirring structure. After the experimental liquid flows into the mixer, it is fully mixed by the stirring structure and supplied to the atomizer 131 for use. The atomizer 131 can mix two or more experimental liquids through the mixer to form the formulated liquid required for the experiment, eliminating the need for the experimenter to complete the mixing outside the device and then pour it into the liquid storage tank 11. It is convenient to mix the experimental liquids from different liquid storage chambers 111, saves experimental operation time, simplifies experimental operation steps, and shortens the experimental time.

[0044] As Figure 3 shown, a one-way solenoid valve 112 for controlling on / off is independently arranged between each liquid storage chamber 111 and the filter 12.

[0045] Specifically, in some embodiments, in order to better control the flow rate of the experimental liquid in each liquid storage chamber 111, a one-way solenoid valve 112 for controlling the water circuit is independently arranged between each liquid storage chamber 111 and the filter 12, and each one-way solenoid valve 112 is electrically connected to the controller 141. The experimenter can operate on the control panel 14 and control the infusion switch state of each liquid storage chamber 111 through the controller 141. The one-way solenoid valve 112 also has the function of one-way circulation. Since multiple liquid storage chambers 111 are uniformly connected to the filter 12, it is inevitable that the experimental liquid will flow back. After using the one-way solenoid valve 112, the backflow of the experimental liquid can be effectively prevented from reversing and refluxing through the one-way solenoid valve 112, so as to avoid the experimental liquid from different positions contaminating the liquid storage chambers 111 at other positions, further ensuring the purity of the experimental liquid, further ensuring the smooth progress of the experiment, and improving the accuracy of the experiment.

[0046] like Figure 5 As shown, the outside of the main unit 1 is provided with a handle 16 for easy gripping, a hook 17 for storing pipelines, and a plurality of steerable and slidable pulleys 15 , and the pulleys 15 are symmetrically arranged on both sides of the bottom of the main unit 1 with respect to the center of the main unit 1 .

[0047] Specifically, in some embodiments, a handle 16 for easy holding, a hook 17 for storing pipelines and a plurality of steerable sliding pulleys 15 are provided on the outer metal shell of the main unit 1. The handle 16 is located at the top of the main unit 1, protrudes in the direction away from the center of the main unit 1 and is provided with a gripping portion for the hand to pass through. The surface of the handle 16 is provided with anti-skid patterns to prevent the hand from slipping. The experimenter can move the main unit 1 to other positions by holding the handle 16, which is convenient for the experimenter to store and carry the gas flow type movable device. The hook 17 is located at the top or side of the main unit 1. The hook 17 extends two semicircular hook claws. The flow type air pipe 3 used by the experimenter can also be hung, magnetically attracted, elastically pressed, clamped, etc. The main unit 1 can be detachably connected to the hanging buckle 17 in different ways, so that the experimenter can store the flow type air tube 3 for storage and transportation. The pulley 15 is arranged at the bottom of the main unit 1. The pulley 15 is symmetrically arranged at the bottom of the main unit 1 with respect to the center of the main unit 1, and the symmetrical arrangement can control the overall center of gravity of the main unit 1 in the central position, so as to avoid the main unit 1 from falling to one side due to the unstable center of gravity of the main unit 1 caused by the experimenter pulling the soft air tube 2 during use, thereby avoiding damage to the main unit 1 and improving the placement stability of the main unit 1. The steerable and sliding pulley 15 can also facilitate the experimenter to pull the soft air tube 2 to move the placement position of the main unit 1, thereby further improving the flexibility of the main unit 1 and expanding the use scope of the gas flow type activity device.

[0048] like Figure 3 and Figure 4 As shown, the soft air tube 2 and / or the flow-type air tube 3 are made of transparent material.

[0049] Specifically, in some embodiments, the flow-type trachea 3 can be made of materials such as transparent and light-transmissive metals, plastics, minerals, etc. The flow-type trachea 3 is an output tool for the experimenter to hold and observe the atomized gas flow pattern. In addition to observing the atomized gas flow pattern externally, the state of the gas flow pattern during internal transportation can also be observed through the transparent flow-type trachea 3. When multiple experimental liquids are mixed and atomized, whether different experimental liquids inside the structure react or change can also be observed through the flow-type trachea 3. The transparent flow-type trachea 3 facilitates the experimenter to further observe the atomized gas flow pattern.

[0050] Specifically, in some embodiments, the flexible trachea 2 can be made of materials such as transparent and light-transmissive metals or plastics. The flexible trachea 2 is an aerosol passage for delivering the aerosol formed by the atomizer 131 to the flow-type trachea 3. In addition to observing the atomized gas flow pattern externally, the state of the gas flow pattern during internal transportation can also be observed through the transparent flexible trachea 2. When multiple experimental liquids are mixed and atomized, whether different experimental liquids inside the structure react or change can also be observed through the flexible trachea 2. The transparent flexible trachea 2 facilitates the experimenter to further observe the atomized gas flow pattern.

[0051] Specifically, in some embodiments, the flexible trachea 2 and the flow-type trachea 3 can be made of transparent materials at the same time to further expand the observable range. The experimenter can observe the flow direction and state of the aerosol in the pipeline structure from the first moment when the aerosol is formed and output by the atomizer 131. If any problem with the aerosol is found, the main machine 1 can also be shut down through the operation control panel 14 immediately to avoid the aerosol continuing to be produced and overflowing to pollute the external experimental environment.

[0052] As Figure 3 and Figure 4 shown, the flow-type trachea 3 is provided with a light-emitting light source 34 for enhancing the display of the gas flow pattern trajectory, and the light-emitting light source 34 can be arranged on the inner side and / or the outer side of the flow-type trachea 3.

[0053] Optionally, in some embodiments, the light-emitting light source 34 can use lamps with different working principles such as incandescent lamps, fluorescent lamps, LED lamps, etc. as tools for providing aerosol trajectory illumination. Preferably, the light-emitting light source 34 uses an LED lamp as the illumination tool. The LED lamp has a high photoelectric conversion efficiency. Compared with traditional incandescent lamps and fluorescent lamps, the LED lamp has lower energy consumption, can save a large amount of energy, and reduce the electricity cost. The service life of the LED lamp is also longer than that of traditional incandescent lamps and fluorescent lamps. The LED lamp reaches the maximum brightness instantly and does not require a warm-up time. Therefore, it is very suitable for places such as experimental sites that need to be switched on and off frequently.

[0054] Specifically, in some embodiments, when the flow pattern gas pipe 3 is made of a transparent material, a light-emitting light source 34 can be installed inside the structure of the flow pattern gas pipe 3. The light-emitting light source 34 is a light source for the gas flow pattern activity device to enhance the display of the gas flow pattern trajectory. The light-emitting light source 34 is electrically connected to the controller 141. Since the aerosol formed after being processed by the atomizer 131 during the experiment may have unclear contours and unobvious traces, and the color of the aerosol may be similar to the surrounding environmental tone, it is difficult for the experimenter to observe the discharged gas flow pattern trajectory. To enhance the display of the gas flow pattern trajectory, the light-emitting light source 34 can use lights of different colors to distinguish from the surrounding environmental tone, improve the recognition degree of the aerosol trajectory, more clearly display the gas flow pattern trajectory, and facilitate the experimenter to observe and record.

[0055] Specifically, in some embodiments, when the flow pattern gas pipe 3 is made of an opaque material, a light-emitting light source 34 can be installed outside the structure of the flow pattern gas pipe 3. Since the aerosol formed after being processed by the atomizer 131 during the experiment may have unclear contours and unobvious traces, and the color of the aerosol may be similar to the surrounding environmental tone, it is difficult for the experimenter to observe the discharged gas flow pattern trajectory. To enhance the display of the gas flow pattern trajectory, the light-emitting light source 34 can use lights of different colors to distinguish from the surrounding environmental tone, improve the recognition degree of the aerosol trajectory, more clearly display the gas flow pattern trajectory, and facilitate the experimenter to observe and record.

[0056] As Figures 1 to 4 shown, the specific implementation manner of Embodiment 1 of the present utility model is as follows:

[0057] The flexible gas pipe 2 and the flow pattern gas pipe 3 of this embodiment are made of an opaque material, and the flow pattern air holes 31 are arranged linearly along the length direction of the flow pattern gas pipe 3.

[0058] Before use, the experimenter opens the liquid storage tank 11, fills the experimental liquid into different liquid storage chambers 111 respectively, then closes the liquid storage tank 11, connects one end of the flexible gas pipe 2 to the main machine connection pipe orifice at the top of the main machine 1 and communicates with the output end of the atomization device 13, and connects the other end of the flexible gas pipe 2 to the input end of the flow pattern gas pipe 3, completing the preliminary preparation work before using the gas flow pattern activity device;

[0059] During use, the experimenter operates on the control panel 14 to open the one-way solenoid valve 112 of the required liquid storage chamber 111, so that the experimental liquid stored in the opened liquid storage chamber 111 can flow to the filter 12. The experimental liquid is filtered by the filter 12 and then transported to the atomizing device 13. The experimental liquid is fully mixed under the stirring of the mixer and then transported to the atomizer 131 for atomization. The aerosol formed after being processed by the atomizer 131 is output to the flexible hose 2 and flows through the flexible hose 2 to the flow pattern air pipe 3. The aerosol enters the flow pattern air chamber 32 and is evenly discharged through the flow pattern air holes 31. The experimenter can observe the gas flow pattern movement track of the discharged aerosol and record it.

[0060] As Figure 5 shown, the specific implementation manner of Embodiment 2 of the present utility model is as follows:

[0061] Different from Embodiment 1, the flow pattern air holes 31 of this embodiment are arranged in a staggered manner along the length direction of the flow pattern air pipe 3 and are spaced at intervals around the central circumference of the tube structure, further expanding the range of the gas flow pattern movement track.

[0062] The specific implementation manner of Embodiment 3 of the present utility model is as follows:

[0063] Different from Embodiment 1 and Embodiment 2, a light-emitting light source 34 is installed outside the flow pattern air pipe 3 in this embodiment.

[0064] During use, the experimenter operates on the control panel 14 to turn on the light-emitting light source 34. The aerosol is output from the main machine connection pipe orifice of the main machine 1. The aerosol flows through the flexible hose 2 to the flow pattern air pipe 3 and is discharged from the flow pattern air holes 31. The light-emitting light source 34 irradiates towards the track range of the aerosol movement, using the light-emitting light source 34 to enhance the movement track of the gas flow pattern, facilitating further observation and recording by the experimenter.

[0065] As Figure 3 and Figure 4 shown, the specific implementation manner of Embodiment 4 of the present utility model is as follows:

[0066] Different from Embodiment 1, Embodiment 2 and Embodiment 3, the flexible hose 2 and the flow pattern air pipe 3 of this embodiment are made of a transparent material, and the light-emitting light source 34 is installed inside the flow pattern air pipe 3.

[0067] During use, the experimenter operates on the control panel 14 to turn on the light-emitting light source 34. The aerosol is output from the main machine connection pipe orifice of the main machine 1. The experimenter can start observing from the time when the aerosol is output through the transparent flexible hose 2 and flow pattern air pipe 3. The aerosol flows through the flexible hose 2 to the flow pattern air pipe 3. The light-emitting light source 34 irradiates towards the track range of the aerosol movement, using the light-emitting light source 34 to enhance the movement track of the gas flow pattern, facilitating further observation and recording by the experimenter.

[0068] The above only further illustrates the technical content of the present utility model by way of embodiments, so as to make it easier for readers to understand, but it does not mean that the implementation manners of the present utility model are limited thereto. Any technical extension or re-creation made according to the present utility model is protected by the present utility model. The protection scope of the present utility model shall be subject to the claims.
