Description

Technical Field

[0001] The present application relates to the technical field of bathroom waterproofing, and in particular to a bathroom waterproofing structure and a construction method thereof. Background Art

[0002] In the building interior decoration project, bathroom waterproofing is a link that is prone to problems in the entire decoration. It is common for water to seep outward from the bathroom door sill, which not only affects normal use, but also causes the ceiling downstairs to crack and the wall to fall off due to water seepage.

[0003] In order to avoid the above situation, a common construction method is to add a water retaining structure at the junction of dry and wet areas, such as a threshold stone. However, although the added threshold stone or water stop structure can block water from seeping outward to a certain extent, after long-term use, water can still be found to seep outward from the interlayer between the adhesive layer and the waterproof layer to affect the dry area in the house, so further improvement is needed. Summary of the invention

[0004] In order to improve the waterproof effect at the threshold of a bathroom, the present application provides a bathroom waterproof structure and a construction method thereof.

[0005] The present application provides a bathroom waterproof structure and a construction method thereof, which adopts the following technical solutions: A bathroom waterproof structure is arranged at the junction of a dry area finish surface and a wet area finish surface, and comprises, from top to bottom, a threshold stone, an adhesive layer arranged on the lower surface of the threshold stone, and a waterproof layer arranged below the adhesive layer, wherein the upper surface of the threshold stone is flush with the upper surface of the dry area finish surface, the upper surface of the threshold stone is higher than the upper surface of the wet area finish surface, and the waterproof layer is laid on the upper surface of the structural base; both sides of the waterproof layer extend to below the dry area finish surface and the wet area finish surface respectively, and the waterproof layer comprises a first area arranged below the wet area finish surface, a second area arranged at the junction of the threshold stone and the wet area finish surface, and a second area arranged below the threshold stone. The third zone is arranged on the side of the wet zone finish surface and the fourth zone is arranged below the dry zone finish surface; the second zone includes a first vertical portion perpendicular to the upper surface of the wet zone finish surface to connect with the first zone, a second vertical portion parallel to the first vertical portion to connect with the third zone, and a telescopic portion arranged between the first vertical portion and the second vertical portion, the upper end of the second vertical portion is higher than the upper end of the first vertical portion, the telescopic portion is elastic, the upper end of the telescopic portion is higher than the upper surface of the wet zone finish surface, the upper end of the telescopic portion is lower than the upper surface of the threshold stone, and a deformable space is formed between the inner surface of the telescopic portion and the surfaces of the first vertical portion and the second vertical portion close to each other.

[0006] By adopting the above technical solution, since the upper end of the telescopic part is higher than the upper surface of the wet area finished surface and lower than the upper surface of the threshold stone, when the water on the wet area finished surface surges to the vicinity of the telescopic part, the water will exert a certain pressure on the telescopic part. Since a deformable space is formed between the telescopic part and the first vertical part and the second vertical part, the telescopic part is squeezed to move toward the threshold stone, and the height of the upper end of the telescopic part can be increased to reduce the amount of water that crosses the telescopic part and enters between the threshold stone and the second vertical part, that is, the possibility of penetrating from the interlayer between the adhesive layer and the waterproof membrane, or between the adhesive layer and the threshold stone toward the dry area finished surface, thereby improving the waterproof effect at the threshold of the bathroom.

[0007] Preferably, the lower middle portion of the telescopic portion is concave toward the upper end close to the second vertical portion.

[0008] By adopting the above technical solution, after water impact, pressure is applied to the concave portion of the middle and lower part of the telescopic part, so as to drive the telescopic part to be squeezed toward the upper end close to the second vertical part, so as to increase the height of the upper end of the telescopic part at this time, thereby improving the water interception range.

[0009] Preferably, the telescopic portion includes a concave piece that is concavely arranged to provide water pushing and a folding piece connected to the concave piece. There are a plurality of folding pieces, and two adjacent folding pieces are staggered. The two adjacent folding pieces can be bent along the connection.

[0010] By adopting the above technical solution, a folding sheet is provided to adapt to the stretching and deformation of water when pushing the inner concave sheet, and the influence of the protruding telescopic part on the sealing effect between the first vertical part and the wet area finished surface when stretching can be reduced.

[0011] Preferably, the third zone includes a first connecting portion parallel to the upper surface of the threshold stone and connected to the second vertical portion, a third vertical portion connected to the first connecting portion, a second connecting portion parallel to the first connecting portion and connected to the third vertical portion, a fourth vertical portion connected to the second connecting portion, and a third connecting portion connected to the fourth vertical portion; the spacing between the third vertical portion and the second vertical portion is greater than the spacing between the fourth vertical portion and the second vertical portion.

[0012] By adopting the above technical scheme, by splitting the third area into several parts, the bonding area between the waterproof layer and the adhesive layer can be extended to improve the bonding effect between the waterproof layer and the adhesive layer, so as to reduce the possibility of water penetrating into the gap between the adhesive layer and the waterproof layer. In addition, due to the provision of the third vertical part, a first turn is formed with the first connecting part, and then a second turn is formed between the second connecting part, and further, a third turn is formed between the second connecting part and the fourth vertical part, and a fourth turn is subsequently formed between the fourth vertical part and the third connecting part. Due to the multiple turns formed, it is more difficult for water flowing from the gap between the second vertical part and the threshold stone to flow, and the flow path is increased, so as to further improve the blocking effect on water flowing through the finished surface of the dry area, reduce the possibility of water penetrating toward the finished surface of the dry area, and thus improve the waterproof effect at the threshold of the bathroom.

[0013] Preferably, the upper surface of the threshold stone is inclined downward toward the direction close to the wet area finished surface, the third connecting portion is connected to the fourth area, and the fourth area and the third connecting portion are both inclined downward toward the direction close to the wet area finished surface.

[0014] By adopting the above technical solution, by setting the upper surface of the threshold stone to be inclined downward in the direction close to the wet area finished surface, the water retained on the upper surface of the threshold stone can flow to the wet area finished surface along the inclined direction, reducing the possibility of water on the threshold stone overflowing to the dry area finished surface. In addition, since the first connecting portion and the second connecting portion are parallel to the upper surface of the threshold stone and are also inclined downward, and the third connecting portion and the fourth area are both inclined downward in the direction close to the wet area finished surface, the difficulty of water flow is further increased, and the flow path of water can be relatively increased, so as to further reduce the possibility of water infiltration in the direction of the dry area finished surface, thereby improving the waterproof effect at the threshold of the bathroom.

[0015] Preferably, a protruding block is provided on the lower surface of the threshold stone, the protrusion is provided between the second vertical portion and the fourth vertical portion, the lower end surface of the protrusion extends to above the first connecting portion, a shaping block is provided between the side wall of the protrusion and the third vertical portion, and the shaping block is provided between the first connecting portion and the second connecting portion.

[0016] By adopting the above technical solution, for the setting of the third zone, firstly, the placement block is placed above the first connecting part coated with the adhesive layer, and a placement space for the protrusion is left between the second vertical part, and then the waterproof layer is laid to form the required third vertical part, etc. After the waterproof layer is laid and the adhesive layer is applied, the threshold stone is installed, and the protrusion is installed in the placement space reserved before. The protrusion is provided, and cooperates with the shaping block, so that the waterproof layer laying process can form the required fourth zone, and the protrusion can block water within a certain range to reduce the possibility of water flowing from the gap of the adhesive layer itself to the waterproof layer.

[0017] Preferably, it also includes a diversion component arranged below the threshold stone to divert water overflowing onto the waterproof layer to the finished surface of the wet area.

[0018] By adopting the above technical solution, after long-term use, there will be a certain gap between the telescopic part and the threshold stone. At this time, some water may flow to the fourth area through the gap between the telescopic part and the threshold stone. Due to the setting of the fourth area itself, it is not easy for the water extending into this area to be diverted to the outside. For this, a diversion component is provided to divert a part of the water to the wet area finish surface, thereby reducing the possibility of excessive water flowing to the dry area finish surface.

[0019] Preferably, the guide component includes a water-absorbing member for absorbing water retained on the third area and an isolation member arranged outside the water-absorbing member to isolate the adhesive layer, the water-absorbing member includes a water-absorbing portion parallel to the length direction of the third connecting portion and drainage portions arranged at both ends of the water-absorbing portion, and the drainage portion extends to above the telescopic portion.

[0020] By adopting the above technical solution, water is absorbed by the water absorbing part, flows to the top of the telescopic part under the guidance of the drainage part, drips on the top of the telescopic part under the influence of gravity, and falls onto the finished surface of the wet area along the telescopic part. Since the length direction of the drainage part is parallel to the width direction of the third connecting part, the drainage part is located above the telescopic part, and it is not easy to flow back to the water absorbing part.

[0021] Preferably, the absorption part includes absorbent cotton, the isolation part includes a sleeve, the sleeve includes a middle tube for the absorption part to pass through and side tubes arranged on both sides of the middle tube for the drainage part to pass through, and the surface of the middle tube close to the waterproof layer is provided with a groove; a spacing is left between the absorption part and the sleeve, the absorption part also includes a sealing part arranged at an end of the drainage part away from the absorption part, the sealing part is detachably connected to the side tube, the side tube is used to seal the port of the side tube away from the middle tube, and the sealing part is connected to the drainage part.

[0022] By adopting the above technical solution, the water-absorbing component and the adhesive layer are isolated by a sleeve, and the groove provided on the middle tube is used for water to pass through to flow to the water-absorbing cotton for absorption, and flow along the drainage part. When not in use, it is installed on the side tube through the sealing part to seal the port of the side tube. When a gap appears between the second vertical part and the threshold stone, the sealing layer is removed from the side tube so that the water that subsequently enters the waterproof layer can be diverted to the wet area finish surface through the diversion component.

[0023] A bathroom waterproofing construction method comprises the following steps: Clean the base: the raised parts on the surface of the base should be flattened, and the concave parts should be filled with polymer mortar; Applying adhesive base: Apply additional coating and paving reinforcing materials on various joints such as facades, corners, around various pipes on the floor, concrete interfaces, cracks, etc.; Apply waterproof coating: After the primer is basically dry and solidified, apply a layer of waterproof coating. After the first layer of coating is solidified, apply the second layer. After the second layer of coating is solidified, check whether the coating thickness meets the requirements. Laying the waterproof layer (5): Laying the waterproof layer (5) from the wet area to the dry area; Laying of the wet area finished surface (2): After the waterproof layer (5) is laid, the floor material in the bathroom is laid after the slope is adjusted according to the elevation line using an adhesive material to form the wet area finished surface (2); Installing the threshold stone (3): After the wet area finished surface (2) is completed, the threshold stone (3) is installed at the junction of the dry area finished surface (1) and the wet area finished surface (2) through the adhesive layer (4).

[0024] In summary, this application has the following beneficial effects: 1. By providing the expansion part, when the water on the wet area finish surface surges to the vicinity of the expansion part, the water will exert a certain pressure on the expansion part to squeeze the expansion part to move toward the direction close to the threshold stone, so that the height of the upper end of the expansion part can be increased to reduce the amount of water that passes over the expansion part and enters between the threshold stone and the second vertical part, that is, the possibility of water penetrating from the interlayer between the adhesive layer and the waterproof membrane, or between the adhesive layer and the threshold stone toward the dry area finish surface, thereby improving the waterproof effect at the threshold of the bathroom.

[0025] 2. By dividing the third area into several parts, the bonding area between the waterproof layer and the adhesive layer can be extended to improve the bonding effect between the waterproof layer and the adhesive layer, so as to reduce the possibility of water penetrating into the gap between the adhesive layer and the waterproof layer. In addition, due to the multiple turns formed, for water flowing from the gap between the second vertical part and the threshold stone, the blocking effect of water flowing through the dry area finish surface can be further improved, reducing the possibility of water penetrating toward the dry area finish surface, thereby improving the waterproof effect at the threshold of the bathroom.

[0026] 3. By providing a diversion component, a portion of the water retained in the third area is diverted to the wet area finish surface, thereby reducing the possibility of excessive water flowing to the dry area finish surface. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-7 , further details of this application are given.

[0030] The embodiment of the present application discloses a bathroom waterproof structure and a construction method thereof.

[0031] Embodiment 1: A waterproof structure for bathroom, referring to Figure 1, arranged at the junction of the dry area finished surface 1 and the wet area finished surface 2, and including, from top to bottom, a threshold stone 3, an adhesive layer 4 arranged on the lower surface of the threshold stone 3, and a waterproof layer 5 arranged below the adhesive layer 4.

[0032] In this embodiment, the upper surface of the threshold stone 3 is flush with the upper surface of the dry area finished surface 1, and the upper surface of the threshold stone 3 is higher than the upper surface of the wet area finished surface 2. The waterproof layer 5 is laid on the upper surface of the structural base layer 6. In this embodiment, the waterproof layer 5 is laid by an elastic waterproof membrane, and both sides of the waterproof layer 5 extend to below the dry area finished surface 1 and the wet area finished surface 2 respectively.

[0033] It should be noted that before laying the waterproofing membrane, the convexities on the surface of the structural base 6 need to be flattened, and the concave areas need to be filled with polymer mortar to form the first leveling layer 61, and then the rubber base is applied to the facade, corners, various pipes around the floor, concrete interfaces, cracks and other joints, and the reinforcing materials are applied and laid. The waterproofing material is applied, and two layers of waterproofing material need to be applied. After solidification and passing the inspection, the waterproofing layer 5 can be laid.

[0034] In this embodiment, the waterproof layer 5 is divided according to the laying area, specifically including a first area 51 arranged below the wet area finished surface 2, a second area 52 arranged at the junction of the threshold stone 3 and the wet area finished surface 2, a third area 53 arranged below the threshold stone 3, and a fourth area 54 arranged below the dry area finished surface 1. Among them, the first area 51 covers the entire wet area, and the second area 52 includes a first vertical portion 521 perpendicular to the upper surface of the wet area finished surface 2 to connect with the first area 51, a second vertical portion 522 parallel to the first vertical portion 521 to connect with the third area 53, and a telescopic portion 523 arranged between the first vertical portion 521 and the second vertical portion 522. In this embodiment, the first vertical portion 521 and the second vertical portion 522 are arranged on the surface where the wet area finished surface 2 and the dry area finished surface 1 are close to each other, and the upper end of the second vertical portion 522 is higher than the upper end of the first vertical portion 521.

[0035] Reference Figure 1 , Figure 2, wherein the telescopic part 523 is elastic, the upper end of the telescopic part 523 is higher than the upper surface of the wet area finished surface 2, the upper end of the telescopic part 523 is lower than the upper surface of the threshold stone 3, and a deformable space is formed between the inner surface of the telescopic part 523 and the surfaces of the first vertical part 521 and the second vertical part 522 that are close to each other. The middle and lower parts of the telescopic part 523 are concavely arranged toward the upper end of the second vertical part 522. Specifically, the telescopic part 523 includes a concave sheet 5231 that is concavely arranged for water to push and a folding sheet 5232 connected to the concave sheet 5231. In this embodiment, the folding sheet 5232 is arranged on the side of the concave sheet 5231 away from the first vertical part 521. There are a plurality of folding sheets 5232, and two adjacent folding sheets 5232 are arranged alternately. The connection between the two adjacent folding sheets 5232 is arranged in an arc shape, and the two adjacent folding sheets 5232 can be bent along the connection. It should be noted that the folding piece 5232 can be arranged in an arc shape or in a plane, depending on the specific requirements. The folding piece 5232 connected to the second vertical portion 522 is arranged in an arc shape.

[0036] Since the waterproof coiled material has a certain flexibility, it is not easy to form the folding sheet 5232 . Therefore, a shaping sheet 5233 is provided on the surface of the folding sheet 5232 close to the second vertical portion 522 to play a shaping role.

[0037] It should be noted that the two ends of the telescopic part 523 are closed and bonded to the side walls of the threshold on both sides. Sealant 524 can be bonded between the side wall of the folding piece 5232 away from the inner concave piece 5231 close to the threshold stone 3 and the upper surface of the wet area finished surface 2, as shown in the figure, to further improve the sealing performance.

[0038] The third area 53 includes a first connection portion 531 parallel to the upper surface of the threshold stone 3 and connected to the second vertical portion 522, a third vertical portion 532 connected to the first connection portion 531, a second connection portion 533 parallel to the first connection portion 531 and connected to the third vertical portion 532, a fourth vertical portion 534 connected to the second connection portion 533, and a third connection portion 535 connected to the fourth vertical portion 534. The height of the first connection portion 531 is higher than the height of the first area 51 and lower than the wet area finished surface 2, the spacing between the third vertical portion 532 and the second vertical portion 522 is greater than the spacing between the fourth vertical portion 534 and the second vertical portion 522, the third connection portion 535 is connected to the fourth area 54, and the fourth area 54 and the third connection portion 535 are both arranged to be inclined downward in a direction close to the wet area finished surface 2.

[0039] In this embodiment, the bonding layer 4 can be formed by curing epoxy mortar, or other adhesives, and is set according to specific needs. The upper surface of the threshold stone 3 is inclined downward toward the direction close to the wet area finished surface 2.

[0040] It should be noted that, for the formation of the third area 53, before applying the waterproof coating, concrete can be poured at the structural base 6 where the dry area and the wet area meet, that is, at the side of the third vertical portion 532 away from the second vertical portion 522 to form a second leveling layer 62. At this time, the side wall of the second leveling layer 62 close to the wet area finished surface 2 is arranged in a vertical Z shape. After the coiled material is laid to form the required first connecting portion 531, the third vertical portion 532, the second connecting portion 533, and the fourth vertical portion 534, the third connecting portion 535 is then abutted against the upper surface of the second leveling layer 62 and extended to the dry area. It should be noted that, for the space between the first connecting part 531, the third vertical part 532 and the second connecting part 533, a shaping block 63 is provided on the second vertical side of the structural base 6 away from the first connecting part 531. The shaping block 63 can be formed by pouring concrete after the fourth area 54 is paved, or a pre-made concrete block can be used as the shaping block 63, which is specifically set according to needs.

[0041] In this embodiment, a prefabricated concrete block is selected as the shaping block 63. After the shaping block 63 is placed, a certain thickness of adhesive is applied to fix the shaping block 63 according to the gaps between the first connecting portion 531, the third vertical portion 532 and the second connecting portion 533. As for the gap between the shaping block 63 and the second vertical portion 522, in this embodiment, a protrusion 31 is protruded from the lower surface of the threshold stone 3. The protrusion 31 is arranged between the second vertical portion 522 and the fourth vertical portion 534. The lower end surface of the protrusion 31 extends to the top of the first connecting portion 531. An adhesive is applied to the first connecting portion 531 and the third connecting portion 535 to bond with the threshold stone 3. After the adhesive is cured, an adhesive layer 4 is formed.

[0042] The present application also discloses a method for waterproofing a bathroom, which specifically includes the following steps: Clean the base: The raised parts on the base surface should be flattened, and the concave parts should be filled with polymer mortar to form the first leveling layer 61. It should be noted that there should be no defects such as hollowing, cracking, sanding, peeling, etc. If there is sand, dust, and oil stains, they should be cleaned up. Concrete is poured at the installation position of the threshold stone 3 according to the needs to form the second leveling layer 62.

[0043] Apply the glue base: additionally apply and lay the reinforcing material on various joints such as the facade, corners, around various pipes on the floor, concrete interfaces, cracks, etc., and then apply it on a large area. When applying, the upper surface and side walls of the second leveling layer 62 need to be painted.

[0044] Apply waterproof coating: After the base glue is basically dry and solidified, configure the proportion of waterproof materials according to the needs. After the ingredients are completed, after the base glue is basically dry and solidified, use a plastic or leather scraper to evenly apply a layer of coating. The force should be uniform and consistent when applying. After the first layer of coating is cured for 7 hours, the hollows, pores, sand, dust rolled into the coating, coating scars and poor curing of the applied coating are repaired, and then the second layer of coating is scraped. The scraping direction must be perpendicular to the scraping direction of the first layer of coating. The total thickness of the coating is controlled at 1.5mm according to the design requirements. After the second layer of coating is cured, check whether the coating thickness meets the requirements. After completion, a water spray test is required. The next process can be carried out only after the test is qualified. It should be noted that the waterproof coating applied needs to be applied to the side wall of the wet area for high-level waterproofing. The specific brushing height is set according to the needs, and the waterproof coating also needs to be applied to the second leveling layer 62 and the side wall of the second leveling layer 62 close to the first leveling layer 61 for waterproofing.

[0045] Laying the waterproof layer 5: Laying the waterproof layer 5 from the wet area to the dry area, and forming the required first area 51, second area 52, third area 53 and fourth area 54 according to needs.

[0046] Laying of wet area finished surface 2: After the waterproof layer 5 is laid, the floor material in the bathroom is laid after the slope is found according to the elevation line with adhesive materials to form the wet area finished surface 2; Installing the threshold stone 3: After the wet area finish surface 2 is completed, the threshold stone 3 is installed at the junction of the dry area finish surface 1 and the wet area finish surface 2 through the adhesive layer 4.

[0047] Embodiment 2: Reference Figure 3 , Figure 4 , which is different from the embodiment 1, in this embodiment, it further includes a guide component 7 disposed under the threshold stone 3 to guide the water overflowing onto the waterproof layer 5 to the wet area finished surface 2. The guide component 7 specifically includes a water absorbing member 71 for absorbing the water retained on the third area 53 and an isolation member 72 disposed outside the water absorbing member 71 to isolate the adhesive layer 4.

[0048] The water absorbing member 71 includes a water absorbing portion 711 parallel to the length direction of the third connecting portion 535 and drainage portions 712 disposed at both ends of the water absorbing portion 711 . The water absorbing portion 711 is specifically disposed on the upper surface of the third connecting portion 535 .

[0049] Reference Figure 4 , Figure 5The absorption part specifically includes absorbent cotton 7111 and a shaping strip 7112 built into the absorbent cotton 7111. The shaping strip 7112 can be a stainless steel wire. The drainage part 712 is fixed to the stainless steel wire. The drainage part 712 extends to the top of the telescopic part 523. It should be noted that the drainage part 712 can be arranged together with the absorbent part 711. However, it should be noted that in order to reduce the possibility of water higher than the telescopic part 523 flowing back to the waterproof layer 5 along the drainage part 712, a partition point can be arranged at one end of the drainage part 712 away from the absorbent part 711. Specifically, the partition point is formed by hot pressing, which can reduce the possibility of water flowing back to the waterproof layer 5 along the drainage part 712. The drainage part 712 can be other flexible plastic sheets, or stainless steel wire, which is specifically arranged according to needs. In this embodiment, the drainage part 712 is specifically a plastic sheet for display, and the plastic sheet is flexible.

[0050] Reference Figure 4 , Figure 6 , wherein the isolating member 72 is specifically a sleeve, which includes a middle pipe 721 for the water absorbing part 711 to pass through and side pipes 722 arranged on both sides of the middle pipe 721 for the drainage part 712 to pass through. The connection between the middle pipe and the side pipe 722 is arranged in an arc shape. The middle pipe 721 abuts against the third connecting part 535 and is parallel to the length direction of the third connecting part 535. A through groove 723 is provided on the surface of the middle pipe 721 close to the waterproof layer 5. The middle pipe 721 is arranged downwardly from the middle part to its two ends in an inclined manner, so that the water in the middle part flows along the middle pipe 721 to the side pipes 722 on both sides, reducing the possibility of water retention in the middle. It should be noted that the middle part of the second leveling layer 62 and the third connecting part 535 can also be arranged in an arched manner in advance to correspond to the subsequent arrangement of the middle pipe 721.

[0051] The side pipe 722 is arranged downwardly and tilted away from the middle pipe, so that the entire sleeve is arranged in a U-shaped tube. It should be noted that there is a gap between the water absorbing member 71 and the sleeve, so that the water absorbing cotton 7111 has a certain space to expand after absorbing water.

[0052] It should be noted that several guide components 7 can be arranged at intervals along the length direction of the threshold stone 3, and the specific arrangement is based on the needs. In the present embodiment, one is specifically arranged to reduce the number of guide components 7 that are arranged too much to affect the connection between the adhesive layer 4 and the threshold stone 3. For this purpose, two side tubes 722 are respectively arranged near the two ends of the threshold stone 3.

[0053] It should be noted that since the absorbent cotton 7111 has a certain service life, it may need to be replaced. The plastic sheets in the new absorbent part 71 are connected by a connecting rope, and the other plastic sheet of the original absorbent part 71 is pulled to pull the new absorbent part 71 into the isolation part 72. After it is pulled to the appropriate position, the connecting rope can be removed for replacement.

[0054] Embodiment 3: Reference Figure 7 , which is different from the first embodiment, the water absorbing member 71 further comprises a sealing portion 724 arranged at one end of the drainage portion 712 away from the water absorbing portion 711, the sealing portion 724 is a rubber plug, the rubber plug is connected to the plastic sheet through an elastic rope 725, the rubber plug is used to seal the port of the side tube 722 away from the middle tube 721, and is detachably connected to the port of the side tube 722 close to the telescopic portion 523 through the elasticity of the rubber plug itself. This is to reduce the possibility that the external water vapor flows along the side tube 722 to the water absorbing portion 711 when the flow guide assembly 7 is not in use.
