Description

Hybrid foaming system Technical Field

[0001] This application relates to the field of cleaning equipment technology, and more particularly to a hybrid foaming system. Background Technology

[0002] Existing foaming cleaning equipment typically uses an independent peristaltic pump to extract cleaning fluid and an independent air pump to extract air for foaming. Because it requires two independent power components, the peristaltic pump and the air pump, the overall product size is large and the number of electronic components is large, which not only increases the manufacturing cost but also places higher demands on battery capacity. Summary of the Invention

[0003] Therefore, it is necessary to provide a hybrid foaming system to address the aforementioned problems.

[0004] The hybrid foaming system provided in this application includes:

[0005] Water inlet assembly, which is connected to an external water source;

[0006] A liquid storage assembly containing a cleaning solution;

[0007] A mixing assembly, comprising a first venturi tube, a mixing pipe, and an air pump, wherein the water inlet assembly is connected to the mixing pipe via the first venturi tube, the negative pressure port of the first venturi tube is connected to the liquid storage assembly, and the air outlet of the air pump is connected to the mixing pipe.

[0008] The mixing foaming system disclosed in this application has a water inlet component connected to a mixing pipe via a first venturi tube, and the negative pressure port of the first venturi tube connected to a liquid storage component. The cleaning liquid is drawn from the liquid storage component by utilizing the negative pressure generated when water flows through the first venturi tube, achieving automatic liquid suction without the need for a separate peristaltic pump. This not only reduces the number of electronic components and the probability of equipment failure, but also reduces the overall size and cost of the product. By connecting the negative pressure port of the first venturi tube to the liquid storage component and the air pump's air outlet to the mixing pipe, the suction of the cleaning liquid and the injection of gas are independently completed by the negative pressure of the water flow and the air pump, respectively. This avoids the air pump bearing the dual load of suction and mixing simultaneously, reducing the demand on air pump pressure and flow rate, thereby reducing the noise impact of the air pump on the entire machine.

[0009] In one embodiment, the mixing assembly further includes a second venturi tube, the inlet of which is connected to the water inlet assembly, and the outlet of which is connected to the mixing pipe.

[0010] The mixing foaming system in the above embodiments further defines the connection between the liquid inlet of the second venturi tube and the water inlet component, and the connection between the liquid outlet and the mixing pipe, so that the system forms two parallel water paths that converge into the mixing pipe. The water flow can be divided into two paths, processed separately, and then merged. The turbulence and shearing effect generated at the merging point of the two water flows enhances the liquid mixing effect.

[0011] In one embodiment, the air pump's air outlet is also connected to the negative pressure port of the second venturi tube.

[0012] The mixing and foaming system in the above embodiments further defines the connection between the air pump's air inlet and the negative pressure port of the second venturi tube, thereby adding an active air intake function to the second venturi tube on the basis of the parallel water circuit. This allows the gas to be injected into the system in two separate multi-point paths. One path is pre-mixed with the water flow in the second venturi tube, while the other path participates in the final mixing in the mixing pipe. This achieves multi-stage segmented mixing of the gas, enhances the bubble generation density, and improves the overall mixing efficiency.

[0013] In one embodiment, the liquid storage assembly includes a liquid storage bottle and a first switching valve, the first switching valve being disposed on a connecting pipe between the liquid storage bottle and the negative pressure port of the first venturi tube.

[0014] When the first switch valve is in the open state, the channel between the liquid storage bottle and the first venturi tube is open; when the first switch valve is in the closed state, the channel between the liquid storage bottle and the first venturi tube is closed.

[0015] The mixing foaming system in the above embodiments further specifies that the first switching valve is set on the connecting pipe between the liquid storage bottle and the negative pressure port of the first venturi tube, actively controlling the opening and closing of the cleaning liquid suction passage. It can block the suction of cleaning liquid when the system does not need to foam, prevent the cleaning liquid from being accidentally aspirated, and avoid waste of cleaning liquid and pipe residue.

[0016] In one embodiment, the water inlet assembly includes a first pipe and a second switching valve. An external water source is connected to the first venturi tube and the second venturi tube respectively through the first pipe. The second switching valve is disposed on the first pipe and is electrically linked to the first switching valve and the air pump. The second switching valve is configured to:

[0017] When the second switching valve is in the open state, it triggers the first switching valve to open and the air pump to start;

[0018] When the second switching valve is in the closed state, it triggers the first switching valve to close and the air pump to shut down.

[0019] The hybrid foaming system in the above embodiments further specifies that when the second switch valve is in the closed state, it triggers the closing of the first switch valve and the air pump. It can automatically cut off the liquid suction passage and stop the air supply while controlling the second switch valve to close, so as to prevent the cleaning liquid from being sucked in or the gas from being injected after the water inlet stops, resulting in residual liquid in the pipeline or wasted power.

[0020] In one embodiment, the water inlet assembly further includes a reversing valve and a second pipe. The reversing valve has a first operating state and a second operating state. When the reversing valve is in the first operating state, an external water source is connected to the first pipe through the reversing valve. When the reversing valve is in the second operating state, an external water source is connected to the second pipe through the reversing valve.

[0021] The mixing foaming system in the above embodiments further defines the reversing valve to have a first working state and a second working state, so that the external water source can be switched between the first pipe and the second pipe, and the same system can be used for two purposes; when the reversing valve is in the second working state, the external water source is connected to the second pipe through the reversing valve, and the water flow bypasses the mixing component and is directly output in pure water mode, which avoids the cleaning liquid being accidentally sucked in when foaming is not required, and reduces pipe residue and cleaning liquid waste.

[0022] In one embodiment, the mixing foaming system further includes a water outlet terminal, which is connected to the mixing pipe and the second pipe respectively, and the mixing pipe and / or the second pipe are provided with foaming fibers.

[0023] The mixing foaming system in the above embodiments further defines that the water outlet terminal is connected to the mixing pipe and the second pipe respectively, so that the foaming water circuit and the pure water circuit share the same water outlet terminal, realizing that the same water outlet terminal can output both foam and clean water, simplifying the product structure; in addition, by setting foaming fibers inside the water outlet terminal and / or the mixing pipe, the initially mixed foam is refined by the physical shearing of the foaming fibers, further improving the density of the foam.

[0024] In one embodiment, the water inlet assembly further includes a hot and cold water switching valve, the external water source includes a hot water channel and a cold water channel, the inlet of the hot and cold water switching valve is connected to the hot water channel and the cold water channel respectively, the outlet of the hot and cold water switching valve is connected to the reversing valve, and the hot and cold water switching valve is used to control the water temperature output to the reversing valve.

[0025] The hybrid foaming system in the above embodiments further defines that the inlet of the hot and cold water switching valve is connected to the hot water channel and the cold water channel respectively, so that the system can simultaneously access both cold and hot water sources, thereby mixing and adjusting the input water temperature to meet the user's different temperature needs; at the same time, the outlet of the hot and cold water switching valve is connected to the reversing valve, so that the warm water regulated by the hot and cold water switching valve is uniformly supplied to the reversing valve.

[0026] In one embodiment, the second switching valve is a water flow magnetic switch or a solenoid valve.

[0027] In one embodiment, a battery module is also included for supplying power to the air pump. Attached Figure Description

[0039] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0040] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate for the embodiments of this application described herein.

[0041] As shown in Figures 1 and 3, this embodiment provides a hybrid foaming system, including:

[0042] Water inlet assembly 10, which is connected to an external water source;

[0043] Liquid storage component 20, which contains cleaning solution;

[0044] The mixing component 30 includes a first venturi tube 31, a mixing pipe 33, and an air pump 34. The water inlet component 10 is connected to the mixing pipe 33 through the first venturi tube 31. The negative pressure port of the first venturi tube 31 is connected to the liquid storage component 20. The air outlet of the air pump 34 is connected to the mixing pipe 33.

[0045] The mixing foaming system disclosed in this application has a water inlet component 10 connected to a mixing pipe 33 via a first venturi tube 31, and the negative pressure port of the first venturi tube 31 connected to a liquid storage component 20. The cleaning liquid is drawn from the liquid storage component 20 by utilizing the negative pressure generated when water flows through the first venturi tube 31. Automatic liquid suction can be achieved without the need for a separate peristaltic pump, which can not only reduce the number of electronic components and the probability of equipment failure, but also reduce the overall size and cost of the product. The connection between the negative pressure port of the first venturi tube 31 and the liquid storage component 20, and the connection between the air pump 34 and the air outlet of the air pump 34 and the mixing pipe 33, allows the suction of the cleaning liquid and the injection of gas to be completed independently by the negative pressure of the water flow and the air pump 34, respectively. This avoids the air pump 34 bearing the dual load of suction and mixing at the same time, reduces the pressure and flow requirements of the air pump 34, and thus reduces the noise impact of the air pump 34 on the whole machine.

[0046] The water inlet assembly 10 can be used to introduce external water into the system and provide a certain water pressure and flow rate; specifically, when foaming is required, the water inlet assembly 10 leads the external water to the first venturi tube 31.

[0047] The liquid storage component 20 can be used to store cleaning liquid, which can be foaming liquids such as shower gel or shampoo.

[0048] The mixing component 30 can be used to mix and foam the input water, gas, and liquid; the mixing component 30 may include a first venturi tube 31, a mixing pipe 33, and an air pump 34; the air pump 34 can be used to provide compressed gas as a gas source for mixing and foaming; the mixing pipe 33 may be a pipe structure with a certain length.

[0049] The water inlet assembly 10 is connected to the mixing pipe 33 via the first venturi tube 31. Specifically, the outlet of the water inlet assembly 10 is connected to the inlet of the water inlet section of the first venturi tube 31, the outlet of the diffuser section of the first venturi tube 31 is connected to the inlet of the mixing pipe 33, and the negative pressure port on the throat of the first venturi tube 31 is connected to the liquid storage assembly 20. When external water enters the first venturi tube 31 at a certain flow rate through the water inlet assembly 10, the water flow accelerates and the pressure drops sharply in the throat, forming a negative pressure zone. The cleaning liquid in the liquid storage assembly 20 is drawn into the throat of the first venturi tube 31 from the negative pressure port. The high shear force of the water flow initially disperses and mixes the cleaning liquid, forming a water-liquid mixture, which flows out from the diffuser section. The water-liquid mixture flows into the mixing pipe 33, and at the same time, the air pump 34 injects compressed air into the mixing pipe 33. The air, liquid, and water are fully mixed in the pipe, thereby forming foam.

[0050] As shown in Figures 2 and 3, in addition to the features of the above embodiments, this embodiment further specifies that: the mixing component 30 also includes a second venturi tube 32, the inlet of the second venturi tube 32 is connected to the water inlet component 10, and the outlet of the second venturi tube 32 is connected to the mixing pipe 33.

[0051] In the above embodiment, the mixing foaming system is connected to the water inlet component 10 through the liquid inlet of the second venturi tube 32 and to the mixing pipe 33 through the liquid outlet, so that the system forms two parallel water paths that converge into the mixing pipe 33. The water flow can be divided into two paths, processed separately, and then merged. The turbulence and shearing effect generated at the merging point of the two water flows enhances the liquid mixing effect.

[0052] The second venturi tube 32 and the first venturi tube 31 form two independent paths for external water to enter the mixing pipe 33. Specifically, the external water is divided into two streams after passing through the water inlet assembly 10. One stream enters the first venturi tube 31, and the other stream enters the second venturi tube 32. The two streams flow out from the first venturi tube 31 and the second venturi tube 32 respectively and merge in the mixing pipe 33.

[0053] It should be noted that when the two water streams are at different flow rates and pressures, turbulence and shearing effects are generated at the confluence of the mixing pipe 33, thereby promoting thorough mixing and foam formation. In addition, when the second venturi tube 32 is equipped with a negative pressure port, the negative pressure port of the second venturi tube 32 can be connected to the air outlet of the air pump 34, or it can be used to extract another liquid, such as a second cleaning solution, fragrance, skin care ingredients, etc. When the second venturi tube 32 is not equipped with a negative pressure port, the liquid flowing into the second venturi tube 32 only undergoes a process of acceleration and depressurization before flowing out.

[0054] In addition, as shown in Figures 4 and 5, the first Venturi tube 31 and the second Venturi tube 32 can be two independent pipe structures or they can be a pipe structure integrally injection molded.

[0055] As shown in Figure 2, in addition to the features of the above embodiments, this embodiment further specifies that the air inlet of the air pump 34 is also connected to the negative pressure port of the second venturi tube 32.

[0056] In the above embodiment, the mixing and foaming system connects the air inlet of the air pump 34 to the negative pressure port of the second venturi tube 32, thereby adding an active air intake function to the second venturi tube 32 on the basis of the parallel water circuit. This allows the gas to be injected into the system in two separate multi-point paths. One path is pre-mixed with the water flow in the second venturi tube 32, while the other path participates in the final mixing in the mixing pipe 33. This achieves multi-stage segmented mixing of the gas, enhances the bubble generation density, and improves the overall mixing efficiency.

[0057] In this process, the air pump 34 directly sends one stream of gas into the mixing pipe 33, and another stream of gas into the negative pressure port of the second venturi tube 32. At this time, the negative pressure port of the second venturi tube 32 serves as an active air inlet, receiving the gas delivered by the air pump 34. The gas is injected into the throat of the second venturi tube 32 and is sheared and dispersed by the high-speed water flow, thereby forming an air-water mixture that flows into the mixing pipe 33.

[0058] It should be noted that the first venturi tube 31 outputs a mixture of water and cleaning fluid to the mixing pipe 33, the second venturi tube 32 outputs a mixture of gas and water to the mixing pipe 33, and the air pump 34 independently outputs a gas path to the mixing pipe 33. The water-liquid mixture, the water-gas mixture, and the gas converge in the mixing pipe 33, resulting in intense turbulent mixing and forming uniform and fine foam.

[0059] As shown in Figure 2, in addition to the features of the above embodiments, this embodiment further defines that: the liquid storage assembly 20 includes a liquid storage bottle 21 and a first switching valve 22, and the first switching valve 22 is disposed on the connecting pipe between the liquid storage bottle 21 and the negative pressure port of the first venturi tube 31.

[0060] When the first switch valve 22 is in the open state, the channel between the liquid storage bottle 21 and the first venturi tube 31 is open; when the first switch valve 22 is in the closed state, the channel between the liquid storage bottle 21 and the first venturi tube 31 is closed.

[0061] In the above embodiment, the mixing foaming system uses a first switching valve 22 installed on the connecting pipe between the liquid storage bottle 21 and the negative pressure port of the first venturi tube 31 to actively control the opening and closing of the cleaning liquid suction passage. This can block the suction of the cleaning liquid when the system does not need to foam, prevent the cleaning liquid from being accidentally aspirated, and avoid waste of the cleaning liquid and pipe residue.

[0062] The liquid storage assembly 20 may include a liquid storage bottle 21 and a first switching valve 22. The liquid storage bottle 21 may be a container for holding cleaning liquid. The first switching valve 22 may be a component for controlling the connection and disconnection between the liquid storage bottle 21 and the negative pressure port of the first venturi tube 31. The first switching valve 22 may be a solenoid valve, and the first switching valve 22 changes its working state according to user instructions or preset programs. Specifically, when foaming is required, the first switching valve 22 is opened, and a liquid passage is formed between the liquid storage bottle 21 and the negative pressure port of the first venturi tube 31. The negative pressure generated when the first venturi tube 31 is working will draw the cleaning liquid from the liquid storage bottle 21. When foaming needs to be stopped, such as in water output mode, power off, or switching to pure water rinsing, the first switching valve 22 is closed. Even if the first venturi tube 31 still generates negative pressure, the cleaning liquid cannot be drawn in.

[0063] As shown in Figure 2, in addition to the features of the above embodiments, this embodiment further specifies that: the water inlet assembly 10 includes a first pipe 11 and a second switching valve 12; an external water source is connected to a first venturi tube 31 and a second venturi tube 32 respectively through the first pipe 11; the second switching valve 12 is disposed on the first pipe 11; the second switching valve 12 is electrically linked to the first switching valve 22 and the air pump 34; and the second switching valve 12 is configured as follows:

[0064] When the second switching valve 12 is in the open state, it triggers the first switching valve 22 to open and the air pump 34 to start.

[0065] When the second switching valve 12 is in the closed state, it triggers the first switching valve 22 to close and the air pump 34 to close.

[0066] The hybrid foaming system in the above embodiment can automatically cut off the liquid suction passage and stop the air supply while controlling the second switch valve 12 to close, by triggering the first switch valve 22 to close and the air pump 34 to close when the second switch valve 12 is in the closed state. This prevents the cleaning liquid from being sucked in or the gas from being injected into the pipeline after the water intake stops, thus preventing residual liquid in the pipeline or wasted power.

[0067] The first pipe 11 can be used to introduce external water and distribute it to the first venturi tube 31 and the second venturi tube 32. The second switching valve 12 can be an electromagnetic switch or a manual mechanical switch that controls whether the first pipe 11 is connected to the first venturi tube 31 and the second venturi tube 32, or it can be a magnetic switch triggered by whether water flows through the first pipe 11. The second switching valve 12 is configured to be electrically linked with the first switching valve 22 and the air pump 34. Specifically, taking the second switching valve 12 as a solenoid valve as an example, when foaming is required, the user issues a command, and the control circuit receives the command to open the second switching valve 12. External water flows sequentially through the first pipe 11 and the solenoid valve into the first venturi tube 31 and the second venturi tube 32. Simultaneously, the control circuit, according to electrical linkage logic, triggers the first switching valve 22 to open and starts the air pump 34, causing the first venturi tube 31 to draw cleaning fluid from the storage bottle 21 and the air pump 34 to simultaneously supply air to the second venturi tube 32 and the mixing pipe 33, achieving mixing and foaming. When foaming is not required, the control circuit closes the second switching valve 12, cutting off the water supply to the first venturi tube 31 and the second venturi tube 32, while simultaneously triggering the first switching valve 22 to close and the air pump 34 to shut down, thus stopping the foaming control system.

[0068] As shown in Figure 2, in addition to the features of the above embodiments, this embodiment further specifies that: the water inlet assembly 10 also includes a reversing valve 13 and a second pipe 14. The reversing valve 13 has a first working state and a second working state. When the reversing valve 13 is in the first working state, the external water source is connected to the first pipe 11 through the reversing valve 13; when the reversing valve 13 is in the second working state, the external water source is connected to the second pipe 14 through the reversing valve 13.

[0069] The mixing foaming system in the above embodiments has a first working state and a second working state through the reversing valve 13, which allows the external water source to switch between the first pipe 11 and the second pipe 14, so that the same system can be used for two purposes. When the reversing valve 13 is in the second working state, the external water source is connected to the second pipe 14 through the reversing valve 13, and the water flow bypasses the mixing component 30 and is directly output in pure water mode. When foaming is not required, it avoids the cleaning liquid being accidentally sucked in, reduces pipe residue and cleaning liquid waste.

[0070] The reversing valve 13 can be used to control the flow direction of the external water source and switch between the first pipe 11 and the second pipe 14, that is, switch between the foaming water path and the clean water path. The reversing valve 13 can be a two-position two-way or three-way structure, and the reversing valve 13 can be set at the inlet of the external water source entering the system. The reversing valve 13 has a first working state and a second working state. Specifically, when the reversing valve 13 is in the first working state, the reversing valve 13 introduces the external water source into the first pipe 11 to participate in the subsequent mixing and foaming process. When the reversing valve 13 is in the second working state, the reversing valve 13 introduces the external water source into the second pipe 14. The second pipe 14 is an independent pipe. One end of the second pipe 14 is connected to the reversing valve 13, and the other end can be connected not only to the hand shower, the top shower head and the rinsing nozzle, but also to directly output pure water without connecting to any terminal.

[0071] As shown in Figure 2, in addition to the features of the above embodiments, this embodiment further specifies that: the mixing foaming system also includes a water outlet terminal 40, which is connected to the mixing pipe 33 and the second pipe 14 respectively, and foaming fibers are provided inside the water outlet terminal 40 and / or the mixing pipe 33.

[0072] In the above embodiment, the mixing foaming system is connected to the mixing pipe 33 and the second pipe 14 through the water outlet terminal 40, so that the foaming water circuit and the pure water circuit share the same water outlet terminal 40, so that the same water outlet terminal 40 can output both foam and clean water, simplifying the product structure; in addition, the foaming fibers are provided inside the water outlet terminal 40 and / or the mixing pipe 33, so that the foam initially formed by mixing is refined by the physical shearing of the foaming fibers, further improving the density of the foam.

[0073] Among them, the water outlet terminal 40 is the final output end of the system, which directly sprays out the foam generated by the mixing pipe 33 or the pure water output from the second pipe 14; the water outlet terminal 40 can be one of a handheld shower head, a top shower head, and a rinsing nozzle.

[0074] Foaming fibers can be used to further refine the initial foam output from mixing pipe 33; the foaming fibers can be composed of multiple layers of metal wire mesh, which breaks down the initial foam into smaller and more uniform foam through physical shearing, thereby improving the fineness of the foam;

[0075] It should be noted that foamed fibers can also be replaced by porous ceramics or sponge-like materials.

[0076] In some examples, the water outlet terminal 40 is designed to be detachable, making it easy for users to remove and clean the foam fibers.

[0077] In addition to the features of the above embodiments, this embodiment further specifies that: the water inlet assembly 10 also includes a hot and cold water switching valve, the external water source includes a hot water channel and a cold water channel, the inlet of the hot and cold water switching valve is connected to the hot water channel and the cold water channel respectively, the outlet of the hot and cold water switching valve is connected to the reversing valve 13, and the hot and cold water switching valve is used to control the water temperature output to the reversing valve 13.

[0078] In the above embodiment, the mixing foaming system is connected to the hot water channel and the cold water channel through the inlet of the hot and cold water switching valve, so that the system can simultaneously receive both cold and hot water sources, thereby mixing and adjusting the input water temperature to meet the user's different temperature needs; at the same time, the outlet of the hot and cold water switching valve is connected to the reversing valve 13, so that the warm water regulated by the hot and cold water switching valve is uniformly supplied to the reversing valve 13.

[0079] The hot and cold water switching valve can be used to mix hot and cold water and adjust the water temperature output to the reversing valve 13, allowing users to select a suitable outlet water temperature according to their needs. Specifically, users can operate the hot and cold water switching valve, such as by rotating the handle, to change the inlet opening of the hot water channel and the cold water channel, so that hot and cold water are mixed in the mixing chamber inside the hot and cold water switching valve to form warm water. The mixed warm water flows out from the outlet of the hot and cold water switching valve and enters the reversing valve 13, and then flows to the first pipe 11 or the second pipe 14 according to the state of the reversing valve 13.

[0080] In addition to the features of the above embodiments, this embodiment further specifies that the second switching valve 12 is a water flow magnetic control switch or a solenoid valve.

[0081] The water flow magnetic switch is a passive detection element used to detect whether water flows through the first pipe 11 and converts the water flow signal into an electrical signal to trigger subsequent linkage control. Specifically, when the reversing valve 13 is in the first working state, external water is introduced into the first pipe 11 through the reversing valve 13. The water flow drives the impeller inside the water flow magnetic switch to rotate, and the magnet on the impeller rotates accordingly. The Hall sensor or reed switch outside the first pipe 11 detects the change in magnetic field and outputs a pulse signal or a switching signal. After receiving the signal, the system's control circuit drives the first switching valve 22 to open and starts the air pump 34. When the reversing valve 13 switches to the second working state, the water flow in the first pipe 11 stops, the water flow magnetic switch outputs a signal, and then the control circuit closes the first switching valve 22 and the air pump 34.

[0082] It should be noted that in some embodiments, when the reversing valve 13 is in the first working state, the control circuit can directly control the first switching valve 22 and the air pump 34 to be closed according to the user's instructions.

[0083] As shown in Figure 3, in addition to the features of the above embodiments, this embodiment further includes a battery module 50, which powers the air pump 34.

[0084] The battery module 50 can be used to provide power to devices such as the air pump 34, enabling the system to operate independently without the need for an external power adapter or a household power outlet. The battery module 50 can be a rechargeable lithium battery pack. It should be noted that the system can also be configured with a power adapter interface, so that when an external power source is connected, the external power source can supply power to the electronic devices.

[0085] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0086] The above embodiments merely illustrate several implementation methods of this application, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent should be determined by the appended claims.
