Description

Technical Field

[0001] This disclosure relates to the field of home appliance technology, and in particular to a foot bath device. Background Technology

[0002] With advancements in production technology, the demand for foot baths and health care is growing stronger. Therefore, people frequently use foot bath equipment for soaking their feet and foot massage. Foot bath equipment typically includes heating, foot massage, and spray functions. The spray function, in particular, uses a water pump to circulate water, creating dynamic water jets or water flow impacts to enhance the comfort and health benefits of the foot bath experience.

[0003] In related technologies, the spray direction of foot bath equipment is relatively simple, making it difficult to meet the different spray needs of users. Utility Model Content

[0004] This disclosure provides a foot bath device that can provide at least two spray directions to better meet the different spray needs of users.

[0005] The technical solution is as follows:

[0006] According to a first aspect of the present disclosure, a foot bath device is provided, including a housing assembly, a spray assembly, a reversing valve assembly, and a water pump. The housing assembly has a foot bath chamber, and the inner wall of the foot bath chamber has a minimum liquid level indicator. At least two spray assemblies are provided, spaced apart within the foot bath chamber. Each spray assembly includes a guide pipe and a spray section communicating with the guide pipe. At least a portion of the guide pipe protrudes from the bottom of the foot bath chamber, such that the initial spray height of the spray section is higher than or equal to the minimum liquid level indicator. The reversing valve assembly is disposed on the housing assembly and communicates with the guide pipes of at least two spray assemblies. The water pump is disposed on the housing assembly and includes an inlet section communicating with the foot bath chamber and an outlet section communicating with the reversing valve assembly. When the reversing valve assembly is in a first switching state, the outlet section communicates with one of the spray assemblies but is isolated from the other spray assemblies. When the reversing valve assembly is in a second switching state, the outlet section communicates with the other spray assembly but is isolated from the other spray assemblies.

[0007] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects:

[0008] When using the spray function, this foot bath device uses a water pump to deliver liquid from the foot bath chamber into the spray assembly, which then sprays it out. When the reversing valve assembly switches to the first switching state, the liquid outlet connects to one of the spray assemblies while isolating it from the others, allowing the user's feet to be sprayed through the spray section of that assembly, thus providing a directional spray within the foot bath tub. When the reversing valve assembly switches to the second switching state, the liquid outlet connects to another spray assembly while isolating it from the others, allowing the user's feet to be sprayed through the spray section of that assembly, thus providing a directional spray within the foot bath tub. In this way, the foot bath device can provide at least two spray directions to better meet the different spraying needs of users.

[0009] The technical solution of this disclosure will be further explained below:

[0010] In one embodiment, when the reversing valve assembly is in the third switching state, the liquid outlet is connected to at least two spray assemblies.

[0011] In one embodiment, at least two spray assemblies include a first spray assembly and a second spray assembly disposed at a distance from the first spray assembly within a foot bath cavity along a first direction.

The second plate is fixed between the through hole and the sealing part, and is inserted into the first liquid outlet channel, and disposed between the second liquid outlet channel and the liquid inlet channel. When the reversing valve assembly is in a first switching state, the first plate is in a first position, so that the second plate seals the second liquid outlet channel while the through hole communicates with the first liquid outlet channel. When the reversing valve assembly is in a second switching state, the first plate is in a second position, so that the second plate opens the second liquid outlet channel while the sealing part seals the first liquid outlet channel.

[0021] In one embodiment, the foot bath device includes a telescopic actuator that is driven to a first plate to drive the first plate to switch between a first position and a second position.

[0022] Alternatively, the valve may also include an operating part fixedly connected to the first plate, the operating part being capable of driving the first plate to switch between a first position and a second position.

[0044] To make the objectives, technical solutions, and advantages of this disclosure clearer, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and do not limit the scope of protection of this disclosure.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure.

[0046] To better understand the foot bath device disclosed herein, the following description is provided in conjunction with the accompanying drawings.

[0047] like Figures 1 to 3 As shown, in some embodiments of this disclosure, a foot bath device 10 is provided, including a housing assembly 100, a spray assembly 200, a reversing valve assembly 300, and a water pump 400. The housing assembly 100 has a foot bath chamber 110, and the inner wall of the foot bath chamber 110 has a minimum liquid level indicator 111. At least two spray assemblies 200 are included and spaced apart within the foot bath chamber 110. Each spray assembly 200 includes a guide pipe 210 and a spray section 220 communicating with the guide pipe 210. At least a portion of the guide pipe 210 protrudes from the bottom of the foot bath chamber 110, such that the initial spray height of the spray section 220 is higher than or equal to the minimum liquid level indicator 111. The reversing valve assembly 300 is disposed in the housing assembly 100 and communicates with the guide pipes 210 of at least two spray assemblies 200. A water pump 400 is disposed in the housing assembly 100. The water pump 400 includes a liquid inlet 410 communicating with the foot bath chamber 110 and a liquid outlet 420 communicating with the reversing valve assembly 300. When the reversing valve assembly 300 is in a first switching state, the liquid outlet 420 is connected to one of the spray assemblies 200 but isolated from the other spray assemblies 200. When the reversing valve assembly 300 is in a second switching state, the liquid outlet 420 is connected to the other spray assembly 200 but isolated from the other spray assemblies 200.

[0048] When the foot bath device 10 uses the spray function, the water pump 400 sends the liquid in the foot bath chamber 110 into the spray assembly 200, and sprays it out through the spray section 220. When the reversing valve assembly 300 switches to the first switching state, the liquid outlet 420 is connected to one of the spray assemblies 200 but isolated from the others, allowing the user's feet to be sprayed through the spray section 220 of that assembly, thus providing a directional spray within the foot bath tub. When the reversing valve assembly 300 switches to the second switching state, the liquid outlet 420 is connected to another spray assembly 200 but isolated from the others, allowing the user's feet to be sprayed through the spray section 220 of that assembly, thus providing a directional spray within the foot bath tub. In this way, the foot bath device 10 can provide at least two spray directions to better meet the different spraying needs of users.

[0049] like Figure 3As shown, in some embodiments, when the reversing valve assembly 300 is in the third switching state, the liquid outlet 420 is connected to at least two spray assemblies 200. Thus, when the foot bath device 10 uses the spray function, by switching the reversing valve assembly 300 to the third switching state, the liquid outlet 420 is connected to at least two spray assemblies 200, facilitating spraying of the user's feet through the spray sections 220 of at least two spray assemblies 200, thereby providing spraying from at least two directions simultaneously within the foot bath tub.

[0050] The specific number of spray units 200 can be flexibly selected according to actual needs, including but not limited to two, three, four, five, etc.

[0051] It should be noted that the reversing valve assembly 300 can be implemented in various ways and can be flexibly set according to the number of spray assemblies 200. For example, when there are three spray assemblies 200, they can be composed of at least two two-way valves, or they can be implemented using a multi-way valve with three or more ports.

[0052] like Figures 1 to 3 As shown, the reversing valve assembly 300 includes a switching valve 310 corresponding to each flow guide pipe 210. The switching valve 310 is disposed on the corresponding flow guide pipe 210 to control the on / off state of the flow guide pipe 210. Figure 1 As shown, when the reversing valve assembly 300 is in the first switching state, one of the switching valves 310 is open while the other switching valves 310 are closed, so that the liquid outlet 420 is connected to one of the spray assemblies 200 but isolated from the other spray assemblies 200.

[0053] And such Figure 2 As shown, when the reversing valve assembly 300 is in the second switching state, another switching valve 310 is opened while other switching valves 310 are closed, so that the liquid outlet 420 is connected to another spray assembly 200 but isolated from other spray assemblies 200.

[0054] And such Figure 3 As shown, when the reversing valve assembly 300 is in the third switching state, the three switching valves 310 are opened, so that the liquid outlet 420 is connected to the three spray assemblies 200, thereby providing spray in three directions simultaneously in the foot bath tub.

[0055] Of course, in other embodiments, when the reversing valve assembly 300 is in the third switching state, at least two switching valves 310 are opened, so that the liquid outlet 420 is connected to at least two spray assemblies 200, thereby enabling spraying in at least two directions to be provided simultaneously in the foot bath tub.

[0056] It should be noted that the on / off valve 310 can be implemented in various ways, including but not limited to at least one of manual valves and electric valves, as long as it can achieve the above-mentioned on / off control.

[0057] like Figures 4 to 9 As shown, at least two spray assemblies 200 include a first spray assembly 230 and a second spray assembly 240 disposed at a distance from the first spray assembly 230 within the foot bath cavity 110 along a first direction. When the reversing valve assembly 300 is in a first switching state, the liquid outlet 420 is connected to the first spray assembly 230 but disconnected from the second spray assembly 240. When the reversing valve assembly 300 is in a second switching state, the liquid outlet 420 is connected to the second spray assembly 240 but disconnected from the first spray assembly 230. Thus, two spray points can be formed in the first direction. For example, when the first direction is the length direction of the foot bath cavity 110, when the reversing valve assembly 300 is in the first switching state, the first spray assembly 230 can spray at least the front of the lower leg. And when the reversing valve assembly 300 is in the second switching state, the second spray assembly 240 can spray at least the back of the lower leg. For example, when the first direction is the width direction of the foot bath cavity 110, when the reversing valve assembly 300 is in the first switching state, the first spray assembly 230 can spray at least the outer side of the calf. When the reversing valve assembly 300 is in the second switching state, the second spray assembly 240 can spray at least the inner side of the calf.

[0058] like Figure 9 As shown, when the reversing valve assembly 300 is in the third switching state, the liquid outlet 420 is connected to the first spray assembly 230 and the second spray assembly 240. Thus, the two spray points formed in the first direction can spray simultaneously to meet the user's needs. For example, when the first direction is the length direction of the foot bath cavity 110, when the reversing valve assembly 300 is in the third switching state, the first spray assembly 230 can spray at least the front of the lower leg, and the second spray assembly 240 can spray at least the back of the lower leg. As another example, when the first direction is the width direction of the foot bath cavity 110, when the reversing valve assembly 300 is in the third switching state, the first spray assembly 230 can spray at least the outer side of the lower leg, and the second spray assembly 240 can spray at least the inner side of the lower leg.

[0059] It should be noted that the first direction includes, but is not limited to, the length direction of the foot bath cavity 110 or the width direction of the foot bath cavity 110.

[0060] Optional, see you later Figure 5As shown, in some embodiments, the foot bath device 10 further includes two foot massage units 500 spaced apart within the foot bath cavity 110 along a second direction, which intersects the first direction. A first spray assembly 230 and a second spray assembly 240 are disposed between the two foot massage units 500. Thus, the first spray assembly 230 and the second spray assembly 240 are positioned between the two foot massage units 500 without interfering with the foot bath device 10's foot massage function. When the foot bath device 10 simultaneously uses both the foot massage function and the spray function, the foot massage units 500 massage the user's feet, and the user can select a comfortable spray direction according to their needs using the reversing valve assembly 300.

[0061] Optionally, such as Figure 5 As shown, the first direction is the X-axis, which is also the length direction of the foot bath cavity 110 and the length direction of the foot massage part 500. The second direction is the Y-axis, which is also the width direction of the foot bath cavity 110 and the width direction of the foot massage part 500. Thus, the first spray assembly 230 is positioned close to the user's toes, while the second spray assembly 240 is positioned close to the user's heels. When the reversing valve assembly 300 is in the first switching state, the first spray assembly 230 is connected to the water pump 400. The water pump 400 can send the liquid in the foot bath cavity 110 into the first spray assembly 230, and spray it out through the spray part 220 to spray the front and sides of the user's calves. When the reversing valve assembly 300 is in the first switching state, the second spray assembly 240 is connected to the water pump 400. The water pump 400 can send the liquid in the foot bath cavity 110 into the second spray assembly 240 and spray it out through the spray section 220 to spray the back and sides of the user's calves.

[0062] It should be noted that the specific implementation of the foot massage part 500 can be achieved using various existing technologies, which will not be elaborated here.

[0063] like Figure 5 As shown, in some embodiments, the spray section 220 of the first spray assembly 230 can spray liquid in all directions. This achieves a shower-like spray effect and increases the spray range.

[0064] The spray section 220 of the second spray assembly 240 can spray liquid at least in the direction of the first spray assembly 230 and diffuse it in the direction of the foot massage section 500. In this way, the spray section 220 of the second spray assembly 240 can spray the back and sides of the user's calves.

[0065] It should be noted that the spray section 220 can be implemented in various ways, including having multiple water outlets, an annular water outlet groove, an arc-shaped water outlet groove, etc. For example, the spray section 220 may include multiple water outlets. The spray section 220 of the first spray assembly 230 may include multiple water outlets arranged at annular intervals to spray liquid in all directions. The spray section 220 of the second spray assembly 240 may include multiple water outlets arranged at fan-shaped intervals to spray liquid towards the first spray assembly 230 and diffuse towards the foot massage section 500. For another example, the spray section may have an annular water outlet groove to spray liquid in all directions. Alternatively, the spray section may have an arc-shaped water outlet groove to spray liquid towards the first spray assembly 230 and diffuse towards the foot massage section 500.

[0066] like Figure 6 As shown, in some embodiments, the inner wall of the foot bath cavity 110 is provided with a maximum liquid level indicator 112 that is higher than the minimum liquid level indicator 111. Along the depth direction of the foot bath cavity 110, the spraying starting height of the spraying part 220 of the first spraying assembly 230 is higher than the minimum liquid level indicator 111 but lower than or equal to the maximum liquid level indicator 112, while the spraying starting height of the spraying part 220 of the second spraying assembly 240 is higher than the maximum liquid level indicator 112. Thus, when the liquid level in the foot bath cavity 110 is lower than the maximum liquid level indicator 112, the first spraying assembly 230 and the second spraying assembly 240 can spray in two directions. When the liquid level in the foot bath cavity 110 is equal to the maximum liquid level indicator 112, the second spraying assembly 240 can spray, while the first spraying assembly 230 can perform a stirring function. Therefore, without adding functional components, the first spraying assembly 230 can perform both spraying and stirring functions, further enhancing the user experience of the foot bath device 10.

[0067] Furthermore, the spray starting height of the spray unit 220 is the minimum height of the spray outlet position, that is, the height of the water outlet of the spray unit 220 closest to the bottom of the foot bath cavity 110. For example, the spray starting height of the spray unit 220 is higher than or equal to the minimum liquid level mark 111, that is, the minimum height of the water outlet of the spray unit 220 is higher than or equal to the minimum liquid level mark 111.

[0068] like Figure 6 As shown, in some embodiments, the spray assembly 200 further includes a connecting pipe 250 communicating with the second liquid outlet channel 323 and the guide pipe 210. Thus, by providing the connecting pipe 250, the positions between the first spray assembly 230 and the second spray assembly 240 can be flexibly set.

[0069] Optionally, the connecting pipe 250 is a flexible hose. In this way, the flexible hose can easily avoid other structures of the foot bath device 10, reducing the difficulty of arranging the foot bath device 10 and making its structure more compact.

[0070] like Figure 7 , Figure 8 as well as Figure 11 As shown, in some embodiments, the reversing valve assembly 300 includes a valve seat 320 disposed in the housing assembly 100 and a valve 330 movable relative to the valve seat 320. The valve seat 320 includes an inlet channel 321 communicating with the outlet section 420, a first outlet channel 322 communicating with the guide pipe 210 of the first spray assembly 230, and a second outlet channel 323 communicating with the guide pipe 210 of the second spray assembly 240. The inlet channel 321 communicates with both the first outlet channel 322 and the second outlet channel 323. When the reversing valve assembly 300 is in a first switching state, the valve 330 closes the second outlet channel 323 and opens the first outlet channel 322. When the reversing valve assembly 300 is in a second switching state, the valve 330 closes the first outlet channel 322 and opens the second outlet channel 323. Thus, the valve 330 can move relative to the valve seat 320 to switch the reversing valve assembly 300 between the first switching state and the second switching state. Specifically, when the reversing valve assembly 300 is in the first switching state, the valve 330 closes the second liquid outlet channel 323, preventing it from connecting with the liquid inlet channel 321, thus preventing the water pump 400 from delivering liquid to the second spray assembly 240. Conversely, the first liquid outlet channel 322 is opened, connecting it with the liquid inlet channel 321, allowing the water pump 400 to deliver liquid to the first spray assembly 230, facilitating spraying of the user by the spray section 220 of the first spray assembly 230. When the reversing valve assembly 300 is in the second switching state, the valve 330 closes the first liquid outlet channel 322, preventing it from connecting with the liquid inlet channel 321, thus preventing the water pump 400 from delivering liquid to the first spray assembly 230. By opening the second liquid outlet channel 323, the second liquid outlet channel 323 is connected to the liquid inlet channel 321, so that the water pump 400 can deliver liquid to the second spray assembly 240, so that the spray section 220 of the second spray assembly 240 can spray the user.

[0071] Optionally, such as Figure 9As shown, in some embodiments, when the reversing valve assembly 300 is in the third switching state, the valve 330 can open the first liquid outlet channel 322 and the second liquid outlet channel 323 respectively. Thus, the valve 330 can move relative to the valve seat 320 to switch the reversing valve assembly 300 between the first switching state, the second switching state, and the third switching state. Specifically, when the reversing valve assembly 300 is in the third switching state, the valve 330 opens the first liquid outlet channel 322 and the second liquid outlet channel 323, so that the first liquid outlet channel 322 and the second liquid outlet channel 323 are respectively connected to the liquid inlet channel 321. This allows the water pump 400 to deliver liquid to the first spray assembly 230 and the second spray assembly 240, facilitating spraying of the user by the spray sections 220 of the first spray assembly 230 and the second spray assembly 240.

[0072] It should be noted that there are several ways to implement the condition that "valve 330 is movably mounted on valve seat 320," as long as it can switch between the first switching state and the second switching state. For example, if valve 330 is slidably connected to valve seat 320, then the directional valve assembly 300 is a linear three-way valve. Another example is that if valve 330 is rotatably connected to valve seat 320, then the directional valve assembly 300 is a rotary three-way valve.

[0073] like Figure 7 as well as Figure 8As shown, in some embodiments, valve 330 includes a first plate 331 and a second plate 332 fixedly connected to the first plate 331. The first plate 331 is slidably disposed on the outside of valve seat 320. The first plate 331 is provided with a sealing part 301 for sealing the first liquid outlet channel 322 and a through hole 302 spaced apart from the sealing part 301. The second plate 332 is fixed between the through hole 302 and the sealing part 301, and the second plate 332 is inserted into the first liquid outlet channel 322 and disposed between the second liquid outlet channel 323 and the liquid inlet channel 321. When the reversing valve assembly 300 is in the first switching state, the first plate 331 is in the first position, so that the second plate 332 seals the second liquid outlet channel 323 while the through hole 302 communicates with the first liquid outlet channel 322. When the reversing valve assembly 300 is in the second switching state, the first plate 331 is in the second position, so that the second plate 332 opens the second liquid outlet channel 323 while the sealing part 301 seals the first liquid outlet channel 322. Thus, the first plate 331 can slide relative to the valve seat 320, enabling the reversing valve assembly 300 to switch between the first and second switching states, and causing the second plate 332 to either seal or open the second liquid outlet channel 323. Specifically, when the reversing valve assembly 300 is in the first switching state, the first plate 331 is in the first position, so that the second plate 332 seals the second liquid outlet channel 323, preventing the second liquid outlet channel 323 from communicating with the inlet channel 321, thereby preventing the water pump 400 from delivering liquid to the second spray assembly 240. At this time, the through hole 302 is connected to the first liquid outlet channel 322, allowing the first liquid outlet channel 322 to connect with the guide pipe 210 through the through hole 302, thereby opening the first liquid outlet channel 322. The first liquid outlet channel 322 is also connected to the liquid inlet channel 321, allowing the water pump 400 to deliver liquid to the first spray assembly 230, facilitating spraying of the user by the spray section 220 of the first spray assembly 230. When the reversing valve assembly 300 is in the second switching state, the first plate 331 is in the second position, and the sealing part 301 seals the first liquid outlet channel 322, closing the first liquid outlet channel 322. This prevents the first liquid outlet channel 322 from connecting with the liquid inlet channel 321, thus preventing the water pump 400 from delivering liquid to the first spray assembly 230. At this time, the second plate 332 is positioned away from the second liquid outlet channel 323 to open the second liquid outlet channel 323, so that the second liquid outlet channel 323 is connected to the liquid inlet channel 321, and the water pump 400 can deliver the liquid to the second spray assembly 240, so that the spray section 220 of the second spray assembly 240 can spray the user.

[0074] like Figure 9As shown, in some embodiments, when the reversing valve assembly 300 is in the third switching state, the first plate 331 is in the third position to open the first liquid outlet channel 322 and the second liquid outlet channel 323. Thus, when the reversing valve assembly 300 switches to the third switching state, the first plate 331 is in the second position (i.e., neither in the first nor the second position), so that the first liquid outlet channel 322 and the second liquid outlet channel 323 are respectively connected to the liquid inlet channel 321. Subsequently, the water pump 400 can deliver liquid to the first spray assembly 230 and the second spray assembly 240, facilitating spraying of the user by the spray sections 220 of the first spray assembly 230 and the second spray assembly 240.

[0075] Since the second plate 332 moves with the first plate 331, and the second plate 332 can be inserted into the first liquid outlet channel 322, the valve 330 and the valve seat 320 are more tightly fitted.

[0076] Furthermore, such as Figures 7 to 9 As shown, in some embodiments, the valve 330 further includes an operating part 333 fixedly connected to the first plate 331, which can drive the first plate 331 to switch between a first position and a second position. Thus, by providing the operating part 333, it is easy to drive the first plate 331 to switch between the first and second positions by toggling the operating part 333. This is easy to implement and simple to assemble.

[0077] like Figures 7 to 11 As shown, in some embodiments, the reversing valve assembly 300 further includes a concave shell 340 fixed within the foot bath cavity 110. The concave shell 340 has a connector 341 disposed opposite to the first liquid outlet channel 322. The connector 341 communicates with the guide pipe 210 of the first spray assembly 230. At least a portion of the valve seat 320 is disposed within the concave shell 340. The first plate 331 is slidably disposed between the concave shell 340 and the valve seat 320. When the reversing valve assembly 300 is in the first switching state, the first plate 331 is in the first position, so that the second plate 332 seals the second liquid outlet channel 323. The connector 341 communicates with the first liquid outlet channel 322 through the through hole 302. When the reversing valve assembly 300 is in the second switching state, the first plate 331 is in the second position, so that the second plate 332 opens the second liquid outlet channel 323. The sealing part 301 is disposed between the connector 341 and the first liquid outlet channel 322 to seal the first liquid outlet channel 322. Thus, the concave shell 340 can protect the valve seat 320 and the valve 330. The first plate 331 is slidably disposed between the concave shell 340 and the valve seat 320, so that the first plate 331 can be leak-proof and does not affect the movement of the first plate 331. At the same time, the connector 341 facilitates the assembly of the reversing valve assembly 300 and the first spray assembly 230.

[0078] like Figures 7 to 10 As shown, in some embodiments, the concave shell 340 is provided with a limiting groove 342 that cooperates with the operating part 333, and the operating part 333 is exposed in the limiting groove 342. In this way, the operation part 333 cooperates with the limiting groove 342, making the movement of the first plate 331 more stable and less prone to shaking.

[0079] Reference Figure 7 as well as Figure 8 It is understood that in some embodiments, the operation part 333 and the limiting groove 342 can also limit the movement range of the first plate 331.

[0080] In some embodiments, the recess 340 is detachably connected to the housing assembly 100. This allows for easy assembly of the directional valve assembly 300 onto the housing assembly 100 using the recess 340. The detachability of the recess 340 from the housing assembly 100 also facilitates maintenance or replacement of the directional valve assembly 300.

[0081] Combination Figure 5 as well as Figure 10 As shown, in some embodiments, the guide pipe 210 and the connector 341 are detachably connected. Thus, when the connector 341 is detached from the guide pipe 210, it facilitates the removal of the first spray assembly 230 from the housing assembly 100. At this time, when the reversing valve assembly 300 switches to the first switching state, the water pump 400 draws liquid from the foot bath chamber 110 and outputs it through the connector 341, facilitating the use of the liquid output from the connector 341 to agitate the liquid in the foot bath chamber 110, achieving a stirring function. When the connector 341 is connected to the guide pipe 210, it facilitates the first spray assembly 230 to perform a spraying function in one direction.

[0082] In other embodiments, the foot bath device includes a telescopic actuator (not shown) that is driven to a first plate to drive the first plate to switch between a first position and a second position.

[0083] Telescopic actuators include, but are not limited to, devices that can directly provide telescopic power, such as linear motors, or can indirectly drive the first plate to slide using telescopic mechanisms such as gear and rack mechanisms or lead screw and nut mechanisms.
