Description

TECHNICAL FIELD

[0001] The utility model relates to a diffusion equipment of solid volatile agent, more particularly to the equipment that utilizes the air supply device to implement diffusion to solid volatile agent and makes the diffusion effect adjustable and controllable. BACKGROUND

[0002] In the application of aromatherapy, pest control and air purification, it is usually necessary to release the volatile agent such as aromatherapy spices, insect repellent, air purifier and disinfectant into the air. In these application scenarios, in addition to using liquid volatile agent, volatile agent is also made into solid cake or pill shape for the convenience of storage, transportation and slow release, such as common aromatherapy cake, mosquito-repellent tablet, camphor pill and granular air freshener.

[0003] Generally, the use of solid volatile agent adopts natural volatilization and intervention volatilization. The natural volatilization is to expose the solid volatile agent to the air and complete the volatilization through natural air circulation, which is mostly used for volatile agent with small volatilization dose or easy volatilization. The intervention volatilization needs external intervention and uses the means of strengthening air circulation to forcibly increase the volatilization speed, that is, the diffusion equipment needs to apply a certain speed of air circulation to the volatile agent.

[0004] The commonly used diffusion equipment adopts a cage structure, and uses a fan or other air supply device to blow air through the solid volatile agent, so that the molecules of the solid volatile agent are wrapped by the air flow and are released into the air through the air holes of the cage structure. The advantage of this structure is simple and portable, but the disadvantages include: ① the cage structure is fixed and semi-open, which can achieve diffusion when the air supply device is working, but still produces natural volatilization when the air supply device stops working, that is, it cannot completely stop volatilization unless the solid volatile agent is taken out and isolated or the entire diffusion equipment is sealed and isolated; ② even if the solid volatile agent has been volatilized for a long time, residues will still be formed at the air flow passage (especially the air holes of the cage structure), which will affect the use experience and cause negative effects due to the long-term residues, deterioration, replacement mixing and other reasons; ③ the diffusion equipment is designed and manufactured in combination with the solid volatile agent, that is, the diffusion equipment is provided with a recess for containing the solid volatile agent, and the size of the recess is consistent with the size of the solid volatile agent, and the bottom and side surfaces are excessively consistent, which not only limits the contact area between the air flow and the solid volatile agent, but also hinders the air flow, which is not conducive to diffusion and aggravates the problem; ④ it is difficult to clean, and there are hidden dangers when it is used for a long time or replaced.

[0005] In some applications, such as compound aromatherapy, various different aromatherapy spices (essential oils) cannot be mixed directly, otherwise uncontrollable chemical reactions will occur, resulting in taste change, failure, and even harm. For such applications, only multiple diffusion devices can be used to work at the same time, which is not only cumbersome to operate, but also when the ratio of various volatile agents in the formula is different, different air volume diffusion devices must be selected. This is almost unrealistic in real-world applications.

[0006] Among them, compound aromatherapy has no practical and user-friendly technical support for market demand for both liquid and solid volatile agents.

[0007] In addition, due to the inherent residual adhesion problem of volatile agents, after working for a period of time, not only will there be residual adhesion at the air outlet position of the diffusion device, but also it may cause residual adhesion on the wall surface, desktop, etc. near the air outlet position of the diffusion device. At the same time, when the diffusion device is placed in a position similar to the wall, corner, or used in the car, the air outlet of the diffusion device facing the wall, corner, window, and storage box wall direction will blow onto the wall, corner, window, and storage box wall, and then diffuse into the space after rebound. On the one hand, it will cause residual adhesion, and on the other hand, it will greatly reduce the diffusion effect.

[0008] In view of the above practical situation, a device is needed to solve the technical defects in the background. SUMMARY

[0009] The present application provides a diffusion device for solid cake-shaped volatile agents to solve the limitations and defects of the current technology listed in the background art and provide a practical solution.

[0010] According to actual needs, one or more embodiments of the present application provide a diffusion device for solid cake-shaped volatile agents to solve the limitations and defects of the current technology listed in the background art and provide a practical solution. The technical scheme of the present application is as follows:

[0011] The diffusion device for solid cake-shaped volatile agents provided by the present application comprises an air supply device for providing air flow, a cake holder in a mesh shape for containing solid cake-shaped volatile agents, an air outlet adjusting device for adjusting the air outlet volume, a control circuit, and a matching shell. The air supply device, cake holder, and air outlet adjusting device are sequentially arranged in order;

[0012] The air supply device is a fan or a blower;

[0013] The shell is divided into two parts of cup body and cover body, wherein the cup body is a wide-mouthed container, one end of which is provided with a cup rim, the inside of which is provided with the cake support, air supply device and control circuit, the bottom of which is provided with an air inlet grid, and the lower outside is fixed with a support foot for providing sufficient ventilation space for the air inlet grid, and the cake support is provided with a groove-shaped cake groove for containing cake-shaped volatile agent; the cover body is a wide-mouthed cover structure, one end of which is provided with a cover rim for being oppositely connected with the cup rim, and the other end and other surfaces thereof are closed.

[0014] The air outlet adjusting device includes an adjusting gauge and an adjusting key, and the relative position between the adjusting gauge and the adjusting key is changed during operation to change the axial distance between the cup body and the cover body, so as to adjust the gap between the cup rim and the cover rim, and the size of the air outlet channel is adjusted.

[0015] As a further technical solution, the periphery of the cake groove is provided with a plurality of air grooves, which provide a channel for the airflow driven by the air supply device on the side of the cake-shaped volatile agent. This solution solves the problem of poor airflow caused by excessive matching of the cake groove and the cake-shaped volatile agent in the conventional technology, and provides a channel for the airflow on the side of the cake-shaped volatile agent.

[0016] Certainly, the effect of this solution can also be achieved by increasing the radial size of the cake groove, but simply increasing the radial size of the cake groove will lose the fixing effect on the cake-shaped volatile agent, 1 which may cause the cake-shaped volatile agent to deviate from the center of the cake groove, causing uneven airflow in all directions, 2 which may cause the cake-shaped volatile agent to move in the cake groove in vehicle applications, resulting in poor application experience. This solution can fix the cake-shaped volatile agent and ensure the side airflow of the cake-shaped volatile agent.

[0017] As a further technical solution, the inside bottom surface of the cake groove is provided with a support point for isolating a gap between the bottom of the cake groove and the cake-shaped volatile agent, for the airflow driven by the air supply device to flow through.

[0018] In the conventional technology, the cake-shaped volatile agent is in close contact with the cake support, and even if a plurality of air inlet holes are provided at the position where the cake-shaped volatile agent is in close contact with the cake support, the airflow channel is blocked due to the close contact of the cake-shaped volatile agent, greatly affecting the diffusion effect.

[0019] This solution separates the cake-shaped volatile agent from the bottom surface of the cake groove by the support point, so that a gap is maintained between the two for the airflow driven by the air supply device to flow through, so that the airflow can flow through the bottom surface of the cake-shaped volatile agent, increasing the contact area between the airflow and the cake-shaped volatile agent and improving the diffusion effect.

[0020] As a further technical solution, the cover body is provided with a support point for isolating a gap between the bottom of the cake groove and the cake-shaped volatile agent, for the airflow driven by the air supply device to flow through.

[0021] The air outlet cover comprises a cylindrical outer wall, a cylindrical inner cylinder concentric with the outer wall, a hollow shaft concentric with the outer wall and the inner cylinder, a plurality of ribs connecting the outer wall and the inner cylinder, and an adjusting key; the adjusting key is three evenly distributed ribs connecting the hollow shaft and the inner cylinder;

[0022] The adjusting gauge is cylindrical, and is fixed to the inside central position of the end of the cover body away from the cover along the central axis. The adjusting gauge faces the end surface of the cover along, and is composed of three groups of curved surfaces with the same size.

[0023] The central axis passes through the axis of the hollow shaft of the air outlet cover, and the air outlet cover is locked on the central axis from the end of the central axis by the fixed cap. The spring is sleeved on the central axis and located between the adjusting key fixed to the center of the air outlet cover and the adjusting gauge fixed to the cover body, and exerts a spring force to make the adjusting key abut against the adjusting gauge. When the air outlet cover rotates along the central axis relative to the cover body, the adjusting key moves along the curved surface of the adjusting gauge, and the axial distance between the air outlet cover and the cover body can be adjusted, so that the distance between the air outlet cover and the cover along changes, thereby changing the air outlet passage.

[0024] The outer side of the outer wall of the air outlet cover is provided with a fixing groove, and the inner side of the cup along is provided with a fixing key matched with the fixing groove of the air outlet cover.

[0025] When the scheme is executed, the cover body assembled with the air outlet cover, the spring and the fixed cap is assembled on the cup body by aligning the fixing groove of the outer wall of the air outlet cover with the fixing key on the cup body, so that the air outlet cover and the cup body are limited by the fixing groove and the fixing key. When the cup cover is rotated, the cup cover and the cup body rotate relative to each other, the adjusting key moves against the adjusting gauge, so that the distance between the cup cover and the cup body changes, that is, the distance between the cup along and the cover along changes, so that the air outlet passage is formed between the cup along and the cover along. When the cup along and the cover along are completely engaged, the air flow passage can be closed to prevent the volatile agent from diffusing outward.

[0026] The scheme solves the problem of uncontrolled diffusion in the traditional technology through the air flow passage with adjustable opening degree.

[0027] As a further technical scheme, the cover along is provided with a reduced diameter section, a plurality of through holes are uniformly distributed on the reduced diameter section to form an air outlet grid, and the adjusting gauge has three uniform sizes and is uniformly distributed on the outside of the reduced diameter section. The adjusting gauge is a concave layer arranged flat along the curved surface of the outside of the reduced diameter section, and the side away from the cover along is composed of multiple curved lines and is used for cooperating with the adjusting key to adjust the distance between the cover along and the cup along. Correspondingly, the adjusting key has three uniform sizes and is uniformly distributed on the inside of the cup along.

[0028] The scheme provides a more simplified technical scheme for adjusting the opening degree of the air flow passage, so that the structure is simpler and the cost is lower.

[0029] Optionally, the cover body is provided with detachable wind baffles, and correspondingly, the cover body is provided with a plurality of groups of wind baffle grooves for mounting the wind baffles, so as to block the air outlet grating in the direction when the wind baffles are mounted on different wind baffle grooves, thereby achieving the purpose of restricting the air diffusion direction.

[0030] The scheme solves the problem of uncontrolled diffusion direction in the traditional technology, so that the diffusion direction can be arbitrarily selected by mounting the wind baffles on different wind baffle grooves.

[0031] As a further technical solution, the cake groove has a plurality of groups, and the amount of volatilization is adjusted by placing different amounts of cake-shaped volatile agents, or the compound diffusion is achieved by placing different varieties of cake-shaped volatile agents.

[0032] The scheme provides technical solutions of ① adjusting the diffusion "dose" by controlling the number of cake-shaped volatile agents, and ② achieving compound diffusion by placing different varieties of cake-shaped volatile agents according to the formula. Compound diffusion can be practically solved in the application of aromatherapy.

[0033] Optionally, the cake support is provided with an independent air supply device corresponding to each cake groove, and correspondingly, the control circuit is provided with a circuit for independently controlling the working state of the air supply device corresponding to each air supply device.

[0034] The scheme further practically realizes the technical solutions of 1 controllable diffusion "metering" and 2 compound diffusion, and hands over the control right to the control circuit, which provides the possibility of improving intelligence.

[0035] As a further technical solution, the inner side of the cup body is provided with a step for supporting the cake support, so that the cake support is detachable to facilitate cleaning.

[0036] The scheme sets a step on the inner side of the cup body, and the cake support is supported by the step and is no longer fixedly arranged on the cup body.

[0037] After diffusion for a period of time, volatile agents will inevitably cause molecular retention and aggregation, thereby forming residues. The traditional integrated structure cannot be cleaned with water due to the built-in air supply device and control circuit, and the components forming residues are mainly the air flow path in contact with the cake-shaped volatile agents and entraining volatile agents.

[0038] This is particularly useful in replacing volatile agent varieties to prevent all volatile agents from being mixed after delivery and causing variations.

[0039] As a further technical solution, a supporting device is arranged outside the cup body for horizontally placing the diffusion device, so that the diffusion device can be placed vertically by the supporting feet and horizontally by the supporting device.

[0040] A hanging column is arranged on the cake support for hanging a cake-shaped volatile agent, so that the diffusion device can be used as a desktop fan when the cover is removed, or can be used for horizontal diffusion by hanging a cake-shaped volatile agent on the hanging column.

[0041] This solution expands the diffusion device to different angles and functions as a desktop fan, making it more versatile and suitable for different needs. BRIEF DESCRIPTION OF DRAWINGS

[0051] Example 1 - Diffusion device with basic structure

[0052] As shown in Figure 1 , the diffusion device with basic structure is composed of a diffusion cover assembly 1 and a diffusion cup assembly 2, wherein:

[0053] As shown in Figure 2As shown, the diffuser assembly 1 comprises a top 11 and a mating head 12, which are integrally formed to create a semi-enclosed cavity 14. The outer diameter of the mating head 12 is smaller than the outer diameter of the top 11, and the joint between the two forms a connecting edge 13. On the outer surface of the mating head 12, three sets of adjusting gauges 15 recessed into the outer wall of the mating head 12 are evenly distributed. The upper edge of the adjusting gauge 15 is a gauge edge 16, which is a multi-segment curve. The mating head 12 is provided with evenly distributed air outlet grilles 17 (such as...). Figure 2 Not all of them are drawn; dotted lines represent the air vents 17 that are continuously and evenly distributed around the entire circumference of the kiss 12.

[0054] like Figure 3 As shown, the diffusion cup assembly 2 consists of a cup body 21 and a base 22. The inner side of the cup body 21 has a cup cavity 23. On the side wall of the cup cavity 23, there are three adjustment keys 24, corresponding to the guide rim 16 in the diffusion hood assembly 1. The cup cavity 23 has a cake holder 25, with a recessed cake groove 27 in the center for holding the cake-shaped volatile agent. The cake groove 27 is evenly distributed with multiple support columns 26 and ventilation grilles 29. Multiple air ducts 28 are also evenly distributed along the edge of the cake groove 27. Inside the cup body below the cake holder 25, there is a horizontally mounted fan (not shown) and a necessary control circuit board (not shown). On the outer side of the cup body 21, there is a power socket 2A and an interactive device 2B, both electrically connected to the control circuit board. An air inlet grille (not shown due to angle) is provided on the lower end face of the cup body 21.

[0055] The base 22 keeps the bottom of the cup body 21 away from the table or desktop on which the diffusion device is placed, providing air intake space for the air intake grille located at the bottom of the cup body 21.

[0056] Figure 4 The figure shows a partial view of the adjustment gauge 15 unfolded into a plane. In this figure, the gauge edge of the adjustment gauge 15 has three strokes, including a first holding section 161, a second adjustment section 162, a second holding section 163, a third adjustment section 164, and a third holding section 165.

[0057] During assembly, the diffuser assembly 1 is aligned with the adjustment gauge 15 of the mating 12 and the adjustment key 24 of the diffuser cup assembly 2, and then installed onto the diffuser cup assembly 2. Under the action of gravity, the adjustment gauge 15 presses against the adjustment key 24 with its gauge edge 16. When the diffuser assembly 1 rotates, the relative position of the gauge edge 16 and the adjustment key 24 changes.

[0058] When the guide edge 16 abuts against the adjustment key 24 at the first holding section 161, the distance between the lower edge 10 of the kiss 12 and the upper edge of the cup body 21 is the farthest, that is, the distance between the connecting edge 13 and the upper edge of the cup body 21 is the farthest. The diffuser assembly 1 and the diffuser cup assembly 2 have their maximum opening. The fan-driven airflow flows out from the gap between them, carrying the volatiles of the flowing disc-shaped volatiles, and diffuses into the surrounding air. Since the first holding section 161 is horizontal, the guide edge 16 and the adjustment key 24 can remain stable at this time. When the diffuser assembly 1 continues to rotate, the guide edge 16 abuts against the adjustment key 24 at the second adjusting section 162, and the distance between the connecting edge 13 and the upper edge of the cup body 21 gradually decreases, expanding... As the opening between the diffuser assembly 1 and the diffuser cup assembly 2 decreases, since the second adjustment section 162 is an inclined plane, when the rotation stops and the diffuser assembly 1 is in a free state, the second adjustment section 162 will continue to move under the action of gravity until the second holding section 163 abuts against the adjustment key 24, and the opening between the diffuser assembly 1 and the diffuser cup assembly 2 enters the second stable section, with the airflow channel being one level smaller; similarly, when the diffuser assembly 1 continues to rotate, when the third holding section 165 abuts against the adjustment key 24, the connecting edge 13 abuts against the upper edge of the cup body 21, and the opening between the diffuser assembly 1 and the diffuser cup assembly 2 is 0, and the airflow is completely blocked.

[0059] Similarly, when the diffuser assembly 1 is rotated in the opposite direction, the opening between the diffuser assembly 1 and the diffuser cup assembly 2 will gradually increase.

[0060] During operation, the device is powered by the power socket 2A. When operating the interactive device 2B, the control circuit board drives the fan to run, driving the airflow into the device from the air inlet grille at the bottom of the cup body 21. The airflow passes through the ventilation grille 29 on the cake tray 25 and blows towards the bottom surface of the cake-shaped volatile agent. Due to the presence of the support column 26, there is a gap between the bottom surface of the cake-shaped volatile agent and the upper surface of the cake tray 27. The airflow flows along this airflow over the bottom surface of the cake-shaped volatile agent, and then flows upward along the multiple air channels 28 on the side of the cake-shaped volatile agent. It passes through the air outlet grille hole 17 on the mating kiss 12 of the diffuser assembly 1 and flows out from the gap between the diffuser assembly 1 and the diffuser cup assembly 2, carrying the molecules of the cake-shaped volatile agent and diffusing them into the surrounding air.

[0061] The advantages of implementing this embodiment are:

[0062] 1) The presence of the support column 26 and the air duct 28 makes the airflow smoother and allows the airflow to flow over the bottom and sides of the cake-shaped volatile agent, enhancing the diffusion effect.

[0063] 2) The presence of the regulating gauge 15 and regulating key 24 allows for multi-level adjustment of the air outlet duct opening, and includes a position for complete closure of the duct. This allows for free adjustment of the diffusion "dosage" and control over complete cessation of diffusion. In other words, from a mechanical structure perspective, it provides a solution for adjusting the diffusion "dosage" and completely shutting down diffusion. Example 2 – Diffusion Device with Restrictible Air Outlet Direction

[0064] This embodiment is based on embodiment 1, with the addition of an adjustable wind deflector to the diffuser assembly 1. Other structures can be referred to in embodiment 1.

[0065] like Figure 5 As shown, on the inner side of the top 11 of the diffuser assembly 1, there are multiple sets of wind deflector grooves 19 for installing wind deflector plates 1A. On the wind deflector grooves 19, there are locking slots 18 for locking the wind deflector plates 1A; correspondingly, there are locking heads 1B on the wind deflector plates 1A.

[0066] During installation, align the clip 1B of the wind deflector 1A with the slot 18 on the wind deflector groove 19, insert the wind deflector 1A into the wind deflector groove 19, and rotate it at an angle. Then, screw the clip 1B into the horizontal section of the slot 18 to fix the wind deflector 1A in the wind deflector groove 19.

[0067] The wind deflector 1A is arc-shaped, and its outer side is close to the air outlet 17 on the mating kiss 12 of the diffuser assembly 1, which can prevent airflow from flowing out of the air outlet 17 at the location of the wind deflector 1A.

[0068] Multiple wind deflectors are arranged along the inner side of the top cover 11. By fixing the wind deflector 1A to different wind deflectors 19, the airflow can be constrained to flow out of the air outlet 17 in different directions, that is, the diffusion direction is adjusted. At the same time, by installing different numbers of wind deflectors 1A, the air volume can also be adjusted, thereby indirectly adjusting the diffusion effect.

[0069] The benefits of implementing this embodiment are that it provides a practical solution for adjusting the diffusion direction and indirectly adjusting the diffusion "dosage" of the device, making it more practical in application scenarios such as near walls, in vehicles, or in corners.

[0070] Example 3 – A horizontally placed, multi-purpose diffusion device

[0071] This embodiment is based on embodiments 1 and 2, with the addition of a support device on the outside of the diffusion cup assembly 2 and a suspension column on the disc holder 25. Other structures can be fully understood by referring to embodiments 1 and 2.

[0072] like Figure 6 As shown, a support rib 2C is provided on the cup body 21 of the diffusion cup assembly 2; a suspension column 2D is added on the disc holder 25.

[0073] Because this diffusion device has an internal fan, after removing the diffusion shroud assembly 1 in embodiments 1 and 2, the obstruction to airflow is removed, and the fan can output sufficient airflow from the cup opening, making it suitable for use as a cooling fan on a desktop or bedside table. The presence of the support rib 2C allows the diffusion cup assembly 2 to be placed horizontally, making it possible to use it as a desktop fan. Combined with the inclusion of natural wind functions on the control circuit board, this fan provides a better user experience.

[0074] When the diffusion function of aromatherapy or mosquito repellent lamp is required, this embodiment also provides a hanging column 2D for suspending the cake-shaped volatile agent (or other solid volatile agents of other shapes) to suspend the aromatherapy cake or mosquito repellent tablet in the airflow to achieve the diffusion function while blowing air.

[0075] It is evident that the benefits of implementing this embodiment are: it provides more usage modes and applications for the diffusion device, making it multi-functional and more practical.

[0076] Example 4 – Diffuser with air outlet adjustment device installed on the cover

[0077] The above embodiments all feature a design where the adjustment gauge of the air outlet adjustment device is located on the cover, while the adjustment button is located on the cup body. This embodiment, however, features a design where both the adjustment gauge and the adjustment button of the air outlet adjustment device are mounted on the cover.

[0078] like Figure 7 , Figure 8 As shown, the air outlet adjustment device consists of an adjustment gauge 15 and an adjustment disc 3, etc., wherein:

[0079] The adjusting gauge 15 is fixed to the inner top of the cover 11 by its three fixing posts 151. Facing the opening of the cover 11, the adjusting gauge 15 has three sets of gauge edges 16 of the same size and shape. The gauge edges 16 are composed of multiple sets of curves; see reference for details. Figure 4 Gain understanding;

[0080] The outer edge of the adjusting disc 3 is circular, and an inner ring 30 is provided concentrically with the outer edge. An air outlet grille 31 is provided between the inner ring 30 and the outer edge. Inside the inner ring 30, an adjusting shaft 32 is provided concentrically with the inner ring 30. Between the inner ring 30 and the adjusting shaft 32, three adjusting keys 24 of the same size and shape, which also serve as connecting ribs, are evenly distributed. The shaft post 36 passes through the central hole of the adjusting shaft 32 and fixes the fixing cap 35 and the spring 34 to the center of the inner top of the cover 11. There is a gap between the central hole of the adjusting shaft 32 and the shaft post 36 so that the two can rotate relative to each other.

[0081] On the outer side of the adjusting plate 3 away from the top of the cover 11, there are multiple positioning notches 33 evenly distributed. The outer diameter of the adjusting plate 3 is smaller than the outer diameter of the cover 11 and also smaller than the inner diameter of the cup. Correspondingly, on the inner side of the cup mouth of the cup, there is a positioning protrusion (not shown) that aligns with the positioning notch 33. Thus, the cover 11 can insert the adjusting plate 3 into the cup by aligning the positioning notch 33 with the positioning protrusion of the cup, thereby realizing the assembly of the diffuser cover and the diffuser cup. After assembly, due to the cooperation of the positioning notch 33 and the positioning protrusion, the adjusting plate 3 and the diffuser cup cannot rotate relative to each other.

[0082] Because there is a gap between the center hole of the adjusting shaft 32 and the shaft post 36, the adjusting disc 3 and the cover 11 can rotate relative to each other, that is, the diffuser cover and the diffuser cup can rotate relative to each other. At the same time, this causes the adjusting gauge 15 and the adjusting key 24 to rotate. (Refer to...) Figure 4 It can be seen that the guide edge 16 and the adjustment key 24 are pressed together. During the rotation, the axial distance between the adjustment disk 3 and the cover 11 is changed, which changes the opening between the edge of the cover 11 and the edge of the diffuser cup—adjusting the size of the air outlet channel, thereby adjusting the diffusion air volume (corresponding to the diffusion "dosage"). During this process, the presence of the spring 34 makes the fit between the adjustment disk 3 and the cover 11 tighter, providing a better adjustment feel.

[0083] The benefits of implementing this embodiment are: 1. It provides more implementation schemes; 2. It makes the air vent adjustment device more compact and improves the adjustment feel, thereby enhancing the user experience.

[0084] The foregoing has described specific embodiments of this specification; other embodiments are within the scope of the appended claims. In some cases, the structure described in the claims can be used to achieve the desired results according to the specific embodiments described above.

[0085] The above description is merely one or more embodiments of this specification and is not intended to limit this specification. For those skilled in the art, the techniques of one or more embodiments of this specification can be combined in new ways to achieve new implementations, or various modifications and variations can be made.
