It should be understood that the orientation descriptions "above", "below", "outside", "inside" involved are all the orientations in the normal use state, and the "left" and "right" directions indicate the left and right directions shown in the specific corresponding schematic diagrams, which may or may not be the left and right directions in the normal use state.

[0027] It should be noted that the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising an..." does not exclude the presence of additional identical elements in the process, method, article or device comprising such element. The term "connected" includes both direct connection and indirect connection unless otherwise specified.

[0028] In some specific embodiments, the cleaning device provided can be used to clean any type of hot plate device. Exemplarily, the bottom plate and the hot plate in the hot plate device can be of a fixed structure, and the distance between the bottom plate and the hot plate is not adjustable. Exemplarily, the bottom plate and the hot plate in the hot plate device can be of a movable structure, and the distance between the bottom plate and the hot plate is adjustable.

[0029] In some embodiments, such as Figure 1 the cleaning device 1 shown includes: an airbag assembly 100, a cleaning cloth 200, and a handle rod 300. At least in a first direction (the first direction is as shown by the arrow in Figure 1 ), the size of the airbag assembly 100 can be changed, and the size of the airbag assembly 100 can be changed in the first direction by inflating or deflating the airbag assembly 100; the cleaning cloth 200 is fixed to the outer surface of the airbag assembly 100, and at least in the first direction, the cleaning cloth 200 covers the outer surfaces on both sides of the airbag assembly 100. Exemplarily, the cleaning cloth 200 can be an integral structure and entirely wrap around the outer surface of the airbag assembly 100. Exemplarily, the cleaning cloth 200 can also be a split structure, and multiple cleaning cloths 200 are respectively fixed to both sides of the airbag assembly 100 in the first direction. One end of the handle rod 300 is connected to the airbag assembly 100, so that the handle rod 300 can extend along the outer surface of the airbag assembly 100.

[0030] During use, the first direction is made parallel to the thickness direction of the hot plate, so that the size of the airbag assembly 100 can be adaptively adjusted according to the distance between the bottom plate and the hot plate, enabling the cleaning device 1 to more conveniently clean the hot plate device. The following describes the principle of the cleaning device 1 being able to more conveniently clean the hot plate device during the use process of cleaning the hot plate device with the cleaning device 1. Before inserting the cleaning device 1 into the hot plate device, the airbag assembly 100 is deflated to facilitate inserting the airbag assembly 100 between the hot plate and the bottom plate of the hot plate device; after the airbag assembly 100 is inserted between the hot plate and the bottom plate, the airbag assembly 100 is inflated so that the surface of the airbag assembly 100 in the first direction can be simultaneously attached to the bottom plate and the hot plate. Since the cleaning cloth 200 covers the outer surfaces on both sides of the airbag assembly 100 in the first direction, in this state, the cleaning cloth 200 can be simultaneously attached to the bottom plate and the hot plate. The inflation state of the airbag assembly 100 can also control the pressing force of the cleaning cloth 200 against the bottom plate and the hot plate. Moreover, the handle rod 300 can extend outside the airbag assembly 100, and the airbag assembly 100 located between the bottom plate and the hot plate can be controlled to move relative to the bottom plate and the hot plate through the handle rod 300, enabling the cleaning cloth 200 to more conveniently wipe the bottom plate and the hot plate. In summary, by controlling the inflation and deflation states of the airbag assembly 100, it is convenient to place the airbag assembly 100 between the bottom plate and the hot plate, and the cleaning cloth 200 fixed to the airbag assembly 100 can be simultaneously attached to and abutted against the bottom plate and the hot plate. At the same time, by extending the handle rod 300 of the airbag assembly 100, it is convenient to operate the position of the airbag assembly 100, enabling the cleaning cloth 200 to more conveniently wipe the bottom plate and the hot plate simultaneously, and further enabling the cleaning device 1 to more conveniently clean the hot plate device.

[0031] An embodiment of the present invention provides a cleaning device for a hot plate device. The cleaning device includes an airbag assembly whose size is variable at least in a first direction, a cleaning cloth fixed to the outer surface of the airbag assembly and covering the outer surfaces on both sides of the airbag assembly at least in the first direction, and a handle rod with one end connected to the airbag assembly. During the process of cleaning the hot plate device with the cleaning device, by controlling the inflation and deflation states of the airbag assembly, it is convenient to place the airbag assembly between the bottom plate and the hot plate, and the cleaning cloth fixed to the airbag assembly can be simultaneously attached to and abutted against the bottom plate and the hot plate. At the same time, by extending the handle rod of the airbag assembly, it is convenient to operate the position of the airbag assembly, enabling the cleaning cloth to more conveniently wipe the bottom plate and the hot plate simultaneously, and further enabling the cleaning device to more conveniently clean the hot plate device.

[0032] Optionally, the shape and size of the airbag assembly 100 perpendicular to the first direction match the size of the hot plate device. Specifically, in a cross-section perpendicular to the first direction, the cross-sectional shapes of both the bottom plate and the hot plate are circular. The size of the airbag assembly 100 in the first direction is variable, while the size perpendicular to the first direction remains unchanged. At the same time, the airbag assembly 100 forms a cylindrical shape, and the cross-sectional shape of the airbag assembly 100 in the first direction is also circular. By making the cross-sectional shape of the airbag assembly 100 the same as that of the bottom plate and the hot plate in a cross-section perpendicular to the first direction, and making the cross-sectional size of the airbag assembly 100 the same as that of the bottom plate and the hot plate, the cleaning cloth 200 can completely cover the surfaces of both the bottom plate and the hot plate at the same time. By operating the handle rod 300 to rotate the airbag assembly 100 one circle between the hot plate and the bottom plate, the cleaning cloth 200 can wipe both the bottom plate and the hot plate comprehensively at the same time. That is, the cleaning device 1 can clean the hot plate device more conveniently and comprehensively.

[0033] In some embodiments, as Figure 1 shown, the number of cleaning cloths 200 is two. In the first direction, the two cleaning cloths 200 are respectively fixed on both sides of the airbag assembly 100. It can be understood that by setting the cleaning cloth 200 as a split structure, if a whole cleaning cloth 200 is wrapped around the outside of the airbag assembly 100, during the process of changing the size of the airbag assembly 100 in the first direction by inflating and deflating, the two parts of the cleaning cloth 200 fixed on the outer surfaces of both sides of the airbag assembly 100 may be pulled or squeezed against each other, resulting in the size change of the airbag assembly 100 being restricted by the cleaning cloth 200 or causing the cleaning cloth 200 to wrinkle, affecting the cleaning effect of the cleaning device 1 on the hot plate device. By respectively fixing the two cleaning cloths 200 on both sides of the airbag assembly 100, during the process of changing the size of the airbag assembly 100 in the first direction by inflating and deflating, there will be no pulling or squeezing between the two cleaning cloths 200, so that the size change of the airbag assembly 100 in the first direction is not restricted by the cleaning cloth 200, and the cleaning cloth 200 will not wrinkle under the action of the pulling force or squeezing force, improving the cleaning effect of the cleaning device 1 on the hot plate device.

[0034] In some embodiments, as Figure 2 shown, in the first direction, the end of the airbag assembly 100 has a connection structure 110, and the cleaning cloth 200 is connected to the airbag assembly 100 through the connection structure. It can be understood that in the first direction, the connection position between the cleaning cloth 200 and the airbag assembly 100 is located at the end of the airbag assembly 100, so that less part of the cleaning cloth 200 is located on the side of the airbag assembly 100 and more part of the cleaning cloth 200 covers the end of the airbag assembly 100, thus enabling the area of the cleaning cloth 200 to be more fully utilized to clean the hot plate device.

[0035] Moreover, the cleaning cloth 200 is detachably connected to the airbag assembly 100 through the connection structure 110. The cleaning cloth 200 can be removed from the surface of the airbag assembly 100 and is convenient for reinstalling at the end of the airbag assembly 100, so as to facilitate the replacement or cleaning of the cleaning cloth 200. Among them, the connection structure 110 can be any structure that can realize the detachable connection of the cleaning cloth 200. Exemplarily, the connection structure 110 can be a binding wire. The cleaning cloth 200 is sleeved on the end face of the airbag assembly 100 and the edge part of the cleaning cloth 200 covers the end part of the side surface of the airbag assembly 100. The binding wire is wound around the outer surface of the edge of the cleaning cloth 200, and by twisting the two ends of the binding wire together, the cleaning cloth 200 can be clamped at the end of the airbag assembly 100. It should be noted that after the two ends of the binding wire are twisted together, they can be reversely loosened, so that the two ends of the binding wire are loosened, so as to be able to release the clamping effect on the cleaning cloth 200, and then the cleaning cloth 200 can be disassembled from the end of the airbag assembly 100.

[0036] In some embodiments, as Figure 2 shown, the connection structure 110 includes a magnetic structure 111 and a metal structure 112. The magnetic structure 111 is located on the outer surface of the airbag assembly 100. Among them, the cleaning cloth 200 can be clamped between the magnetic structure 111 and the metal structure 112, so that the cleaning cloth 200 can be detachably fixed to the airbag assembly 100 through the magnetic attraction between the magnetic structure 111 and the metal structure 112. By applying an external force to the metal structure 112 to separate the metal structure 112 from the magnetic structure 111, the clamping of the cleaning cloth 200 by the metal structure 112 and the magnetic structure 111 can be released, so that the cleaning cloth 200 can be disassembled from the airbag assembly 100. Moreover, the installation and disassembly of the cleaning cloth 200 can be more conveniently realized through the magnetic structure 111 and the metal structure 112. Optionally, the number of the magnetic structure 111 and the metal structure 112 can be multiple. Multiple magnetic structures 111 are arranged at intervals around the circumference of the airbag assembly 100, and the metal structures are arranged at intervals around the circumference of the airbag assembly 100. Each metal structure 112 is respectively attracted to each magnetic structure 111, so that the cleaning cloth 200 can be more reliably fixed to the airbag assembly 100. Moreover, since the metal structure 112 is a split structure, there is no mutual acting force between the separated metal structures 112, so that the installation and disassembly of each metal structure 112 can be more convenient; Optionally, the magnetic structure 111 can be an integral annular structure, and the metal structure 112 can be an integral annular structure. The magnetic structure 111 surrounds the outer surface of the airbag assembly 100, and the metal structure 112 can be sleeved on the outside of the airbag assembly 100 and attracted to the magnetic structure 111, so as to further simplify the operation steps of the attraction between the metal structure 112 and the magnetic structure 111.

[0037] In some embodiments, as Figure 3 shown, the airbag assembly 100 includes an airbag housing 120 and an airbag body 130. The airbag housing 120 has an accommodation cavity 121 inside. In a first direction (the first direction is as indicated by the arrow in Figure 3 ), the size of the airbag housing 120 can be changed. Exemplarily, the airbag housing 120 has a corrugated structure, and a plurality of corrugated structures are arranged at intervals in the first direction. The corrugated structure can generate deformation in the first direction, so that the size of the airbag housing 120 in the first direction can be changed; Exemplarily, the airbag housing 120 includes a flexible part and a guiding part. The flexible part is movably connected to the guiding part, and the guiding part extends in the first direction to limit the deformation of the flexible part in directions other than the first direction, so that the size of the airbag housing 120 in the first direction can be changed. The airbag body 130 is located in the accommodation cavity 121. The airbag body 130 can change its own volume by inflating and deflating, so that the size of the airbag housing 120 in the first direction changes, and further the size of the airbag assembly 100 in the first direction changes. By wrapping the airbag body 130 with the deformable airbag housing 120, the airbag assembly 100 can be deformed while protecting the airbag body 130, thereby extending the service life of the airbag body 130.

[0038] Optionally, as Figure 3 shown, the airbag assembly 100 further includes a support member 140. In a direction perpendicular to the first direction, the support member 140 is fixed to the end of the airbag body 130 to support the airbag body 130 and limit the deformation of the airbag body 130 in a direction perpendicular to the first direction, improving the deformation speed of the airbag body 130 in the first direction under the same maximum volume change, and also improving the service life of the airbag body 130.

[0039] In some embodiments, as Figure 4As shown, the handle rod 300 includes a handle body 310 and a ventilation pipe 320. The handle body 310 is rotatably connected to the airbag housing 120. By holding the handle body 310, the airbag assembly 100 can be moved inside the hot plate device. During the movement of the airbag assembly 100, the handle body 310 can rotate relative to the airbag assembly 100 according to the holding position and the relative position of the airbag assembly 100, so that the user can more conveniently operate the position of the airbag assembly 100. At the same time, a part of the ventilation pipe 320 is located inside the handle body 310 and a part extends outside the handle body 310. The part of the ventilation pipe 320 that extends outside the handle body 310 is communicated with the airbag body 130. It can be understood that the handle rod 300 integrates the handle body 310 for operating the position of the airbag assembly 100 and the ventilation pipe 320 for inflating or deflating the airbag body 130, so that while the handle rod 300 can achieve more functions, the structure of the handle rod 300 is more compact. At the same time, the part of the ventilation pipe 320 that extends outside the handle body 310 is a flexible pipe. It should be noted that since a part of the ventilation pipe 320 is located inside the handle body 310, during the rotation of the handle body 310 relative to the airbag assembly 100, the ventilation pipe 320 will also tend to rotate relative to the airbag body 130. In order to ensure a certain airtightness between the ventilation pipe 320 and the airbag body 130, the end of the ventilation pipe 320 is fixedly connected to the airbag body 130 so that no relative rotation can occur. If the part of the ventilation pipe 320 that extends outside the handle body 310 is set as a rigid pipe, there may be movement interference between the ventilation pipe 320 and the airbag body 130. By setting this part as a flexible pipe, during the relative rotational movement between the handle body 310 and the airbag assembly 100, this part can generate adaptive deformation, thereby reducing the possibility of movement interference between the ventilation pipe 320 and the airbag body 130.

[0040] In some embodiments, such as Figure 4As shown, one end of the vent pipe 320 communicating with the airbag body 130 is provided with a one-way valve 321, and the other end opposite to the end of the vent pipe 320 communicating with the airbag body 130 is provided with an inflation structure 322. The one-way valve 321 is used to allow gas to enter the airbag body 130 and block the gas from flowing out of the airbag body 130. Through the one-way valve 321, the inflation structure 322 can inflate the airbag body 130 through the vent pipe 320 and block the gas in the airbag body 130 from leaking out of the airbag body 130 through the vent pipe 320. The inflation structure 322 can be any structure that can introduce gas into the interior of the airbag body 130 through the vent pipe 320. Exemplarily, the inflation structure 322 can be an air pump. Exemplarily, the inflation structure 322 can also be a hand-held airbag. The hand-held airbag can absorb the air outside the cleaning device, and by squeezing the hand-held airbag, the air can be introduced into the interior of the airbag body 130 through the vent pipe 320. Moreover, by setting the inflation structure 322 at the end of the vent pipe 320, while enabling the handle rod 300 to achieve more functions, the structure of the handle rod 300 becomes more compact.

[0041] In some embodiments, in combination with Figure 3 and Figure 4 , the airbag body 130 further has an electronic exhaust valve 131, and the handle body 310 has an operation structure 311. The operation structure 311 is used to control the opening and closing of the electronic exhaust valve 131. Exemplarily, the operation structure 311 can be a button or a touch screen. By operating the operation structure 311, the opening and closing of the electronic exhaust valve 131 can be controlled. In a state where the airbag body 130 needs to be deflated, the electronic exhaust valve 131 is opened through the operation structure 311 so that the airbag body 130 can exhaust air. After the airbag body 130 finishes exhausting air, the electronic exhaust valve 131 is closed through the operation structure 311, so that the airbag body 130 stops exhausting air. Moreover, by arranging the operation structure 311 on the outer surface of the handle body 310, the handle rod 300 can also control the exhaust of the airbag body 130, enabling the handle rod 300 to achieve more functions.

[0042] In some embodiments, in combination with Figure 4 and Figure 5, a pressure sensor 132 is provided inside the airbag body 130, and a pressure display 312 is provided on the outer surface of the handle body 310. The pressure display 312 is used to display the pressure value detected by the pressure sensor 132. Specifically, the pressure sensor 132 can obtain the pressure value inside the airbag body 130, and the pressure display 312 can obtain the pressure value obtained by the pressure sensor 132 and display it through an image, so that the pressure inside the airbag body 130 can be read through the pressure display 312, and then the pressure inside the airbag body 130 can be determined according to the pressure value, and whether to inflate or deflate the airbag body 130 can be determined according to the pressure value. Optionally, the operating structure 311 is directly provided on the outer surface of the handle body 310, and the operating structure 311 can also be provided on the pressure display 312.

[0043] In some embodiments, as Figure 6 shown, the end of the handle body 310 is rotatably connected to the airbag housing 120 through a universal ball 313. The handle body 310 can rotate relative to the airbag housing 120 around the center of the universal ball 313, so that the rotation direction of the handle body 310 relative to the airbag housing 120 is more free, and thus the operation of the displacement of the airbag assembly 100 by the handle body 310 is more convenient. Optionally, as Figure 6 shown, the airbag housing 120 further includes a mounting seat 122. The mounting seat 122 is fixedly connected to the airbag housing 120 and the mounting seat 122 protrudes from the outer surface of the airbag housing 120 to form a mounting end. The universal ball 313 is rotatably connected to the mounting end of the mounting seat 122, so as to facilitate the installation of the universal ball 313 and the airbag housing 120.

[0044] The above is only a preferred embodiment of the present invention, and is not used to limit the protection scope of the present invention.
