Description

Technical Field

[0001] This application belongs to the field of medical device technology, and more specifically, relates to a shortwave therapy handpiece and a shortwave therapy device. Background Technology

[0002] Shortwave therapy is a medical instrument that uses high-frequency electromagnetic fields to produce thermal and non-thermal effects on the body. Its working principle involves outputting an electric field through capacitive electrodes to promote local blood circulation and improve tissue nutrition, resulting in anti-inflammatory, analgesic, antispasmodic, and tissue repair-promoting effects. Sensitive skin has a thinner stratum corneum and insufficient moisture, leading to a weakened skin barrier function and making it less resistant to external stimuli. Shortwave therapy, through a shortwave treatment handpiece placed close to the skin, provides radiofrequency heating and fluid replenishment, showing significant effects, especially for sensitive skin.

[0003] Chinese patent application CN201710567916.9 discloses a handle and device for treating sensitive skin. The handle includes a grip shell, a radio frequency (RF) component, a hydration component, a treatment head, and a dispensing knob. The RF component and hydration component are housed within the grip shell, and the treatment head is located at the end of the grip shell. The treatment surface of the treatment head has an outlet hole for the treatment liquid from the hydration component to flow out. However, the patent does not specifically disclose the delivery structure of the treatment liquid from the hydration component to the outlet.

[0004] Most shortwave therapy devices on the market use diaphragm pumps in their handpieces. Diaphragm pumps rely on the reciprocating motion of a diaphragm to deliver liquid, producing a strong pulse. Initially, this results in a rather forceful jet of liquid, reducing the user experience. Therefore, existing shortwave therapy handpieces suffer from uneven liquid distribution during application. Utility Model Content

[0005] Therefore, it is necessary to provide a shortwave therapy handpiece and a shortwave therapy device to solve the technical problem of uneven liquid output from the shortwave therapy handpiece in existing shortwave therapy devices.

[0006] According to one aspect of this application, a shortwave therapy handpiece is provided, comprising a housing, a liquid storage structure, a liquid conduit, a peristaltic pump, and a radio frequency component. The liquid conduit, the peristaltic pump, and the radio frequency component are all disposed within the housing. The housing has a treatment end, the radio frequency component is disposed at the treatment end, and the treatment end has a liquid outlet. The liquid outlet of the liquid conduit is connected to the liquid outlet, and the liquid storage structure is connected to the liquid inlet of the liquid conduit. The liquid storage structure and the peristaltic pump, as well as the peristaltic pump and the liquid outlet, are connected through the liquid conduit. The peristaltic pump is used to deliver liquid from the liquid storage structure to the liquid outlet.

[0007] Optionally, a liquid inlet is provided on the end face of the outer shell away from the treatment end, the liquid inlet end of the liquid pipeline is connected to the liquid inlet, and the liquid storage structure is detachably connected to the outer shell and connected to the liquid inlet.

[0009] Optionally, the outer casing includes a gripping housing and a treatment head housing. The liquid tubing and peristaltic pump are disposed inside the gripping housing, and the radio frequency component is disposed inside the treatment head housing. The gripping housing is provided with a liquid outlet channel, and the liquid tubing is connected to the liquid outlet channel. The liquid outlet is disposed on the end face of the treatment head housing away from the gripping housing. A liquid guide tube is disposed on the end face of the treatment head housing close to the gripping housing. One end of the liquid guide tube is detachably inserted into the liquid outlet channel, and the other end of the liquid guide tube is connected to the liquid outlet.

[0010] Optionally, the gripping housing includes a front cylinder and a rear cover, with a liquid outlet channel located at one end of the front cylinder and an opening at the other end of the front cylinder, and the rear cover removably covering the opening.

[0011] Optionally, the shortwave therapy handpiece also includes a connector disposed within the grip housing, the connector being mounted on the rear cover, the peristaltic pump being mounted on the connector, and the connector being provided with a buckle for engaging liquid tubing.

[0012] Optionally, the shortwave therapy handpiece also includes a first one-way valve disposed within the housing, the first one-way valve being connected to a liquid reservoir structure and used to balance the air pressure within the liquid reservoir structure.

[0013] Optionally, the shortwave therapy handpiece also includes a three-way connector disposed within the housing, the three-way connector being connected to the liquid line, the liquid reservoir and the first one-way valve respectively.

[0014] Optionally, the shortwave therapy handpiece also includes a gas line and a second one-way valve. The outlet end of the gas line is located inside the housing and connected to the liquid line. The inlet end of the gas line extends to the outside of the housing. The second one-way valve is located inside the housing and is disposed in the gas line. The second one-way valve is used to restrict the flow of liquid in the liquid line to the inlet end.

[0015] The beneficial effects of the shortwave therapy handpiece provided in this application are as follows: Compared with the prior art, the shortwave therapy handpiece of this application includes a shell, a liquid storage structure, a liquid pipeline, a peristaltic pump, and a radio frequency component. The liquid pipeline, peristaltic pump, and radio frequency component are all disposed within the shell. The shell has a treatment end, the radio frequency component is disposed at the treatment end, and the treatment end has a liquid outlet. The liquid outlet of the liquid pipeline is connected to the liquid outlet, the liquid storage structure is connected to the liquid inlet of the liquid pipeline, and the peristaltic pump is disposed in the liquid pipeline. The peristaltic pump is used to deliver the liquid in the liquid storage structure to the liquid outlet. Thus, compared with the diaphragm pump commonly used in shortwave therapy handpieces in the prior art, the shortwave therapy handpiece of this application uses a peristaltic pump to deliver the liquid in the liquid storage structure to the liquid outlet of the treatment end. The peristaltic pump forms a liquid column by squeezing the tubing with rollers, which has the advantages of continuous, uniform, and predictable infusion. This makes the liquid output of the shortwave therapy handpiece of this application more uniform and improves the user experience.

[0038] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0040] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0041] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0042] According to one aspect of this application, an embodiment of this application provides a shortwave therapy device, which includes a main unit (not shown) and a shortwave therapy handle electrically connected to the main unit.

[0043] According to another aspect of this application, embodiments of this application provide a shortwave therapy handpiece, which can be seen in conjunction with the following description. Figures 1 to 5 The shortwave therapy handpiece includes a housing 1, a liquid reservoir 2, a liquid tubing 3, a peristaltic pump 4, and a radiofrequency assembly 5.

[0044] The liquid pipeline 3, the peristaltic pump 4, and the radio frequency component 5 are all housed within the housing 1. The housing 1 has a treatment end 130, and the radio frequency component 5 is located in the treatment end 130. The treatment end 130 has a liquid outlet 121. The liquid outlet 310 of the liquid pipeline 3 is connected to the liquid outlet 121. The liquid storage structure 2 is connected to the liquid inlet 320 of the liquid pipeline 3. The liquid storage structure 2 and the peristaltic pump 4, as well as the peristaltic pump 4 and the liquid outlet 121, are all connected through the liquid pipeline 3. The peristaltic pump 4 is used to transport the liquid in the liquid storage structure 2 to the liquid outlet 121.

[0045] It should be noted that the liquid in the liquid storage structure 2 is one or more of the following: clean water, toner, lotion, medicine, serum, lotion, etc.

[0046] It is understood that the peristaltic pump 4 and radio frequency component 5 of the shortwave therapy handpiece are electrically connected to the main unit. The main unit can supply power to the peristaltic pump 4 and the radio frequency component 5, and control the on / off state and power of the peristaltic pump 4 and the radio frequency component 5. After the peristaltic pump 4 is activated, it can deliver the liquid in the liquid storage structure 2 to the liquid outlet 121. After the radio frequency component 5 is activated, it can output an electric field to produce a warming effect on the skin. This makes the shortwave therapy handpiece of this application have both radio frequency heating function and liquid replenishment function, which is particularly effective for the treatment of sensitive skin. At the same time, the radio frequency component 5 warms the skin surface, which can open the pores, allowing the skin to absorb the liquid more fully. That is, the radio frequency heating function can promote the liquid replenishment function.

[0047] It is understood that the peristaltic pump 4 and the radio frequency component 5 of the shortwave therapy handpiece of this application can work independently to provide a single radio frequency heating function or a single fluid replenishment function. The peristaltic pump 4 and the radio frequency component 5 can also work simultaneously to provide both radio frequency heating and fluid replenishment functions. The function mode of the shortwave therapy handpiece is selected by the user on the control panel of the host.

[0048] Specifically, the radio frequency component 5 includes a first circuit board 510 and an electrode pad 520 electrically connected together. The first circuit board 510 is initially powered and controlled by the host, and then powers and / or controls the electrode pad 520. The electrode pad 520 forms the end face of the treatment end 130, and a liquid outlet 121 is formed on the electrode pad 520. It is understood that the liquid outlet 121 is isolated from the electrical components of the electrode pad 520 to prevent short circuits in the electrode pad 520.

[0049] In this embodiment, the shortwave therapy handpiece includes a housing 1, a liquid storage structure 2, a liquid pipeline 3, a peristaltic pump 4, and a radio frequency component 5. The liquid pipeline 3, peristaltic pump 4, and radio frequency component 5 are all housed within the housing 1. The user can control the start / stop and / or rotation speed of the peristaltic pump 4 via the control panel of the main unit. Once started, the peristaltic pump 4 delivers the liquid from the liquid storage structure 2 to the outlet 121 of the treatment end 130, thereby spraying the liquid onto the patient's skin. Compared to the diaphragm pump commonly used in existing shortwave therapy handpieces, the shortwave therapy handpiece of this application uses a peristaltic pump 4 to deliver the liquid from the liquid storage structure 2 to the outlet 121 of the treatment end 130. The peristaltic pump 4 forms a liquid column by squeezing the tubing with rollers, offering the advantages of continuous, uniform, and predictable low-speed infusion. This results in a more uniform liquid output from the shortwave therapy handpiece, improving the user experience.

[0050] Specifically, the peristaltic pump 4 includes a pump head and a planetary geared stepper motor connected together. The pump head contains a flexible tube and rollers for squeezing the tube. The liquid pipeline 3 has two sections: one section connects to the liquid storage structure 2 and the flexible tube, and the other section connects to the flexible tube and the outlet 121. The planetary geared stepper motor is connected to the rollers of the pump head and is electrically connected to the main unit. The planetary geared stepper motor drives the rollers to rotate, and the rollers squeeze the flexible tube to form a liquid column, achieving continuous and uniform delivery of liquid at low speed. It is understood that the peristaltic pump 4 is an existing product of the prior art. This application only describes the basic principle of the peristaltic pump 4, and the specific structure of the peristaltic pump 4 is not described here.

[0051] Therefore, the peristaltic pump 4 used in the shortwave therapy handpiece of this application also has the advantages of excellent isolation, low probability of leakage and low probability of contamination. The roller of the peristaltic pump 4 squeezes the hose, and the liquid in front of the squeezed section is pushed out to form a liquid column. The fluid of the peristaltic pump 4 is isolated in the hose, which reduces the leakage problem of the pump body itself and avoids the contamination of the fluid by the pump internal components (such as metal pistons and gears) or the corrosion of the pump by the fluid.

[0052] In one embodiment, please refer to [the relevant documentation / reference]. Figure 1 , Figure 2 and Figure 5 The shortwave therapy handpiece also includes a control switch 12 mounted on the housing 1. The control switch 12 includes a button 1210 and a second circuit board 1220. The second circuit board 1220 is fixed inside the housing 1 and electrically connected to the main unit. The button 1210 is mounted on the second circuit board 1220. The top of the button 1210 protrudes from the outer surface of the housing 1. The user can control the opening and closing of the peristaltic pump 4 by pressing the button 1210.

[0053] Furthermore, the second circuit board 1220 and the peristaltic pump 4 are electrically connected to the host, and the user controls the start and stop and / or speed of the peristaltic pump 4 through the host; or, the user controls the start and stop and / or speed of the peristaltic pump 4 by pressing the button 1210 a few times in a short period of time.

[0054] In another embodiment, a liquid inlet 1121 is provided on the end face of the outer shell 1 away from the treatment end 130. The liquid inlet end 320 of the liquid pipeline 3 is connected to the liquid inlet 1121. The liquid storage structure 2 is detachably connected to the outer shell 1 and is connected to the liquid inlet 1121.

[0055] Optionally, the detachable connection between the liquid storage structure 2 and the outer casing 1 can be achieved by a threaded connection, or by screws, or by a snap-fit ​​710, without any limitation.

[0056] Preferably, please refer to the following: Figure 1 , Figure 2 and Figure 5 The liquid storage structure 2 is a liquid storage tank, which is a cylindrical shell component with an open end. The liquid storage structure 2 and the outer shell 1 are connected by threads. The threaded connection between the two shells has the advantages of simple structure, easy processing, simple assembly, no need for special equipment for disassembly and assembly, reliable connection and strong load-bearing capacity.

[0057] In other embodiments, the liquid storage structure 2 may not be directly connected to the outer casing 1; instead, the liquid storage structure 2 may be connected to the liquid inlet 1121 via a pipe. Therefore, there are multiple options for the installation location of the liquid storage structure 2. For example, the liquid storage structure 2 can be installed inside the main unit of the shortwave therapy device, or the liquid storage structure 2, the outer casing 1, and the main unit can all be independent components.

[0058] In summary, the installation location of the liquid storage structure 2 and the connection method between the liquid storage structure 2 and the liquid inlet 1121 can be selected according to actual needs, and no single limitation is made here.

[0059] In one specific embodiment, please refer to the following: Figure 2 and Figure 5 The shortwave therapy handpiece also includes an annular sealing gasket 6 located at the liquid inlet 1121. The annular sealing gasket 6 is used to seal the connection between the outer shell 1 and the liquid storage structure 2, significantly reducing the possibility of leakage from the liquid storage structure 2.

[0060] For example, please refer to the following: Figure 2 and Figure 5 The diameter of the inner ring surface of the annular sealing gasket 6 is smaller than the diameter of the liquid inlet 1121, meaning that part of the annular sealing gasket 6 is located within the liquid inlet 1121. During the process of screwing the liquid storage structure 2 to the rear cover 112, the liquid storage structure 2 can achieve a seal by pressing against the annular sealing gasket 6. The portion of the annular sealing gasket 6 located within the liquid inlet 1121 completely rests on the end face of the tee connector 9, so that the end face of the tee connector 9 can provide support for the annular sealing gasket 6, improving the pressing contact effect between the liquid storage structure 2 and the annular sealing gasket 6, thereby improving the sealing performance at the end face of the liquid storage structure 2 and further reducing the possibility of leakage from the liquid storage structure 2.

[0061] In an optional embodiment, the housing 1 can be a one-piece structure with good sealing performance. The housing 1 can also be a separate structure, with the housing containing the radio frequency component 5 serving as the treatment head, which can be a consumable.

[0062] In some embodiments, please refer to the following: Figure 2 and Figure 3The outer shell 1 includes a grip shell 110 and a treatment head shell 120. A liquid pipeline 3 and a peristaltic pump 4 are disposed inside the grip shell 110. A radio frequency component 5 is disposed inside the treatment head shell 120. The grip shell 110 is provided with a liquid outlet channel 1111. The liquid pipeline 3 is connected to the liquid outlet channel 1111. The liquid outlet 121 is disposed on the end face of the treatment head shell 120 away from the grip shell 110. A liquid guide tube 122 is disposed on the end face of the treatment head shell 120 near the grip shell 110. One end of the liquid guide tube 122 is detachably inserted into the liquid outlet channel 1111, and the other end of the liquid guide tube 122 is connected to the liquid outlet 121.

[0063] With the above configuration, the treatment head housing 120 can be detached from the grip housing 110, and the treatment head can be used as a consumable. The treatment head is used as a consumable for two reasons: firstly, to ensure cleanliness and hygiene, as the treatment head needs to be replaced for different patients; secondly, different sizes of treatment heads are required for different body parts.

[0064] The liquid guide tube 122 connects the liquid outlet channel 1111 and the liquid outlet 121, and at the same time realizes the detachability of the treatment head housing 120 and the liquid transfer between the grip housing 110 and the treatment head housing 120.

[0065] Specifically, the first circuit board 510 of the radio frequency assembly 5 is disposed on the inner surface of the treatment head housing 120 near the gripping housing 110, and the electrode plate 520 of the radio frequency assembly 5 forms the end face of the treatment end 130. A circuit board is disposed inside the gripping housing 110, and the first circuit board 510 and the circuit board inside the gripping housing 110 are connected together by an electrical connection structure. For example, the electrical connection structure can be an electrical plug and an electrical socket.

[0066] In one specific embodiment, please refer to the following: Figure 1 , Figure 2 and Figure 4 The gripping housing 110 includes a front cylinder 111 and a rear cover 112. The liquid outlet channel 1111 is provided at one end of the front cylinder 111, and the other end of the front cylinder 111 is provided with an opening. The rear cover 112 is detachably covered by the opening.

[0067] The grip housing 110 is designed with a detachable front cylinder 111 and a rear cover 112. When assembling the shortwave therapy handle, the front cylinder 111 and the rear cover 112 can be separated, and the components can be easily installed into the grip housing 110. After the installation is completed, the front cylinder 111 and the rear cover 112 can be connected, which reduces the assembly difficulty of the shortwave therapy handle.

[0068] Optionally, the detachable connection between the front cylinder 111 and the rear cover 112 can be achieved by a threaded connection, or by screws, or by a clip 710, without any limitation.

[0069] Preferably, the rear cover 112 and the front cylinder 111 are connected by a thread. The threaded connection between the two shells has the advantages of simple structure, easy processing, easy assembly, no need for special equipment, reliable connection and strong load-bearing capacity.

[0070] In a more specific embodiment, please refer to Figure 2 The shortwave therapy handle also includes a connecting seat 7 disposed in the grip housing 110, the connecting seat 7 is installed on the rear cover 112, the peristaltic pump 4 is installed on the connecting seat 7, and the connecting seat 7 is provided with a buckle 710 for engaging the liquid pipeline 3.

[0071] In this way, by fixing the liquid pipe 3 with the buckle 710, not only can the liquid pipe 3 be prevented from winding, but also the liquid pipe 3 can be prevented from rubbing against the inner wall of the outer casing 1, thus preventing the liquid pipe 3 from wearing.

[0072] Understandably, the peristaltic pump 4 is relatively large. To reduce the size of the shortwave therapy handpiece, the cavity of the front cylinder 111 cannot be made too large. If the peristaltic pump 4 were installed inside the front cylinder 111, its physical mounting structure would easily occupy space in the front cylinder 111, increasing the difficulty of installing other components. Therefore, by mounting the peristaltic pump 4 on the rear cover 112, its mounting structure can be located on the rear cover 112, avoiding occupying space in the front cylinder 111 and reducing the assembly difficulty of the shortwave therapy handpiece.

[0073] Optionally, the peristaltic pump 4 and the connecting seat 7, as well as the connecting seat 7 and the rear cover 112, are detachably connected together. The detachable connection can be made by screws or by clips 710, which is not the only one.

[0074] Specifically, the rear cover 112 is generally in the shape of a hemispherical shell. Two ribs 1122 are arranged opposite each other on the inner wall surface of the rear cover 112. The ribs 1122 are provided with a first threaded hole 1123. The peristaltic pump 4 is detachably installed on the rear cover 112 by the cooperation of screws and the first threaded hole 1123.

[0075] In some embodiments, please refer to the following: Figure 1 and Figure 2 The shortwave therapy handpiece also includes a first one-way valve 8 disposed inside the housing 1. The first one-way valve 8 is connected to the liquid storage structure 2 and is used to balance the air pressure inside the liquid storage structure 2.

[0076] Understandably, when liquid begins to enter the peristaltic pump 4 from the liquid storage structure 2, the amount of liquid in the liquid storage structure 2 decreases, the air pressure inside the liquid storage structure 2 begins to decrease, and the difficulty for liquid to enter the peristaltic pump 4 increases. However, due to the presence of the first one-way valve 8, after the air pressure inside the liquid storage structure 2 decreases, the first one-way valve 8 allows gas outside the liquid storage structure 2 to enter the interior of the liquid storage structure 2, balancing the air pressure inside the liquid storage structure 2 and reducing the difficulty for liquid to enter the peristaltic pump 4.

[0077] Optionally, the first check valve 8 can be directly connected to the liquid storage structure 2, and the two can be integrated into one component and designed as consumables; or the first check valve 8 can be directly connected to the liquid inlet 1121 of the outer shell 1, and the liquid storage structure 2 can also be directly connected to the liquid inlet 1121, that is, the first check valve 8 is indirectly connected to the liquid storage structure 2, and only the liquid storage structure 2 is designed as a consumable.

[0078] In one specific embodiment, the shortwave therapy handle also includes a three-way connector 9 disposed within the housing 1. The three-way connector 9 is connected to the liquid pipeline 3, the liquid storage structure 2, and the first one-way valve 8, respectively. The first one-way valve 8 is disposed within the housing 1, which not only reduces the assembly difficulty of the liquid pipeline 3, the liquid storage structure 2, and the first one-way valve 8, but also improves the sealing performance of the connection.

[0079] With the above settings, only the liquid storage structure 2 is designed as a consumable, reducing the user's operating costs.

[0080] Specifically, the first one-way valve 8 is glued together with the three-way connector 9, and the liquid pipeline 3 is connected to the three-way connector 9 through a straight-through Luer connector. A little glue is first applied between the liquid pipeline 3 and the straight-through Luer connector and / or between the straight-through Luer connector and the three-way connector 9 before threading them together.

[0081] Preferably, please refer to Figure 4 The inner surface of the back cover 112 has four second threaded holes 1124. The tee connector 9 is detachably installed on the back cover 112 by the cooperation of screws and the second threaded holes 1124.

[0082] For example, please refer to the following: Figure 2 and Figure 4 The rear cover 112 is provided with a groove 1125, and the annular sealing gasket 6 is provided in the groove 1125. After the tee connector 9 is fastened to the rear cover 112 by screws, the annular sealing gasket 6 is pressed between the tee connector 9 and the rear cover 112 to achieve the fixation of the annular sealing gasket 6.

[0083] Furthermore, both the first one-way valve 8 and the three-way connector 9 are located inside the housing 1, which not only reduces the possibility of the first one-way valve 8 being bumped or knocked, but also improves the aesthetics of the shortwave therapy handle.

[0084] In other embodiments, please refer to [the relevant documentation]. Figure 1 and Figure 2 The shortwave therapy handpiece also includes a gas line 10 and a second one-way valve 11. The outlet end 1010 of the gas line 10 is located inside the housing 1 and connected to the liquid line 3. The inlet end 1020 of the gas line 10 extends to the outside of the housing 1. The second one-way valve 11 is located inside the housing 1 and is disposed in the gas line 10. The second one-way valve 11 is used to restrict the flow of liquid in the liquid line 3 to the inlet end 1020.

[0085] With the above settings, the shortwave therapy handpiece of this application can not only replenish the user's moisture, but also enhance the beauty effect by combining it with gas.

[0086] Optionally, the gas in the gas pipeline 10 is oxygen, ozone, or hydrogen, or other gases that can be used for facial beauty treatments.

[0087] Preferably, the gas in the gas pipeline 10 is oxygen. High-pressure oxygen, as a carrier, can "push" moisture and nutrients (such as vitamins, peptides, hyaluronic acid, etc.) into the stratum corneum of the skin to achieve deep hydration and nourishment. Oxygen can promote cell metabolism and accelerate blood circulation, and has a very good calming and repairing effect on sensitive, red, or post-laser or microneedling skin. Oxygen also has a certain improving effect on acne-prone skin.

[0088] Furthermore, the outer casing 1 is also provided with a flexible protective sleeve 13, in which the gas pipeline 10, the wires of the aforementioned circuit boards and the wires of the peristaltic pump 4 are inserted. The protective sleeve 13 can prevent the gas pipeline 10 and the wires from being worn.

[0089] 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.

[0090] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the 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 application should be determined by the appended claims.
