Description

Technical Field

[0001] This utility model relates to the field of PVC massage pool technology, specifically to an inflation and deflation structure for a PVC massage pool. Background Technology

[0002] PVC massage pools are a common household or commercial leisure product. They need to be inflated before use and deflated for storage after use. Existing inflation / deflation systems typically involve a simple air nozzle on the pool, connected to an external pump. However, the air nozzle or mounting base is often made of rigid plastic, which, during repeated inflation / deflation and storage, easily causes friction and pressure against the soft PVC inner wall of the pool, leading to wear and even cracking and air leakage, severely affecting the product's lifespan. Therefore, a new inflation / deflation structure for PVC massage pools is proposed. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides an inflation and deflation structure for a PVC massage pool.

[0004] The technical solution adopted by this utility model to solve its technical problem is an inflation / deflation structure for a PVC massage pool, including an inflation / deflation structure comprising a mounting sleeve, an annular fan housing, and an internal threaded cover. The mounting sleeve comprises a rigid PVC sleeve, with an annular piece integrally connected to the outer periphery of one end of the rigid PVC sleeve. A threaded interface is provided on the inner wall of one end of the rigid PVC sleeve. A rubber sleeve is fitted around the outer periphery of the rigid PVC sleeve away from the annular piece. The inner periphery of the rubber sleeve near the end of the rigid PVC sleeve is an inwardly extending inclined surface, and the outer periphery of the rigid PVC sleeve near the end of the rubber sleeve is an outwardly extending inclined surface. The rigid PVC sleeve and the rubber sleeve... The inclined surfaces are mutually matched and fixed by gluing. The inclined surface structure can increase the surface area of ​​the contact surface. The mounting sleeve is used to install with the outer layer structure of the PVC massage water pool. The mounting sleeve is inserted into the inflation cavity of the PVC massage water pool until the ring plate contacts the outer surface of the PVC massage water pool. The ring plate is then glued and fixed to the outer surface of the PVC massage water pool. After the mounting sleeve enters the inflation cavity of the PVC massage water pool, the use of the rubber sleeve can reduce the hard contact between the mounting sleeve and the inside of the PVC massage water pool. Therefore, after deflation and storage, the contact damage to the material surface of the PVC massage water pool is reduced, avoiding wear and tear on the PVC massage water pool and improving the stability of subsequent use.

[0005] Specifically, the annular fan housing has an exhaust threaded connector and an inlet threaded connector that correspond to the threaded interface at both ends. An axial flow fan is installed inside the annular fan housing. The exhaust end of the axial flow fan faces the exhaust threaded connector. The internal threaded cover is threadedly connected to the exhaust threaded connector or the inlet threaded connector.

[0006] With the exhaust threaded connector and the air inlet threaded connector installed, personnel can assemble the exhaust threaded connector or the air inlet threaded connector to the threaded interface of the mounting sleeve according to the inflation or deflation needs. This allows the axial flow fan to supply or exhaust air to the mounting sleeve, thereby inflating or deflating the inflation chamber of the PVC massage pool. After inflation or deflation, the inner threaded cover can be threaded onto the exhaust threaded connector or the air inlet threaded connector to isolate the inflation chamber of the pool from the outside. Rubber sealing rings are glued to the fitting points of the exhaust threaded connector, the air inlet threaded connector, and the inner threaded cover.

[0007] Specifically, an annular baffle is integrally connected to the inner side of the air inlet threaded connector. An annular magnet is embedded on one side of the annular baffle, and the annular magnet is glued and fixed to the annular baffle. An annular iron ring is magnetically connected to one side of the annular baffle through the annular magnet. An iron filter screen is welded to the inside of the annular iron ring. The surfaces of the annular iron ring and the filter screen are both nickel-plated and chromium-plated.

[0008] Specifically, both the mounting sleeve and the internal threaded cover are fixedly connected to a handle on their outer periphery.

[0009] By adopting the above technical solution, the handle facilitates the rotation of the corresponding mounting sleeve or internal threaded cover by the operator.

[0010] The beneficial effects of this utility model are: The inflation and deflation structure of the PVC massage pool described in this utility model effectively avoids hard contact between the mounting sleeve and the inner wall of the pool by combining the inclined surfaces of the rigid PVC sleeve and the flexible rubber sleeve. This greatly reduces wear and scratches on the pool material during storage and extends the product's lifespan.

[0011] The present invention discloses an inflation and deflation structure for a PVC massage pool. The annular fan housing integrates inflation and deflation functions. Users can easily inflate or deflate the pool by simply switching the connection direction. The operation is simple, and the handle enhances the convenience of operation.

[0012] The present invention discloses an air inflation and deflation structure for a PVC massage pool. The filter screen at the air inlet end is magnetically installed, making disassembly and cleaning very convenient. This helps to maintain the cleanliness of the inflated air and ensure the long-term stable operation of the equipment. Attached Figure Description

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] like Figure 1-4 As shown, the inflation / deflation structure of a PVC massage pool according to this utility model includes an mounting sleeve 11, an annular fan housing 12, and an internally threaded cover 13. The mounting sleeve 11 is used to fix it to the pool wall. Its core is a rigid PVC sleeve 111, with an integrally formed annular piece 112 at one end. During installation, the mounting sleeve 11 is inserted into the pre-drilled mounting hole of the PVC massage pool until the annular piece 112 is in contact with the outer surface of the pool. Then, the annular piece 112 is firmly bonded to the outer surface of the pool with adhesive. A rubber sleeve 114 is fitted onto the end of the PVC sleeve 111 away from the ring 112. To ensure a firm fit, the outer surface of the rigid PVC sleeve 111 at this end is machined into an outwardly extending inclined surface, while the corresponding position on the inner surface of the rubber sleeve 114 is machined into an inwardly extending inclined surface with a matching slope. The two are fixed together by gluing. When the mounting sleeve 11 is inserted into the inflatable cavity of the pool, this flexible rubber sleeve 114 becomes the part that contacts the inner wall of the pool after the pool is stored, thereby preventing the rigid PVC from directly scratching the inner wall.

[0017] At one end of the rigid PVC sleeve 111, there is a threaded interface 113 formed by internal threads, which is used to connect the annular fan housing 12.

[0018] An axial flow fan 123 is installed inside the annular fan housing 12. Both ends of the annular fan housing 12 are integrally connected to an exhaust threaded connector 121 and an inlet threaded connector 122, both with external threads that can engage with the threaded interface 113 of the mounting sleeve 11. When inflation is required, the exhaust threaded connector 121 is screwed into the threaded interface 113, and the axial flow fan 123 is started. Air is drawn in from the inlet end and discharged into the water tank air chamber from the exhaust end. When deflation is required, the entire annular fan housing 12 is rotated, and the inlet threaded connector 122 is screwed into the threaded interface 113. At this time, the axial flow fan 123 draws air from the air chamber from the inlet end. To release air, when the fan is not in use, the exposed exhaust threaded connector 121 or inlet threaded connector 122 can be covered with the inner threaded cap 13 to maintain a seal. All threaded connection interfaces are fitted with rubber sealing rings to ensure airtightness. When sealing is required after inflation, the inner threaded cap 13 can be placed over the inlet threaded connector 122 before the axial flow fan 123 is turned off. The wiring of the axial flow fan 123 extends to the outside of the annular fan housing 12, and the contact surface between the wiring and the annular fan housing 12 is sealed with hot melt adhesive, so that the power supply components at the pool site can provide power to the axial flow fan 123.

[0019] Inside the air inlet threaded connector 122, an annular baffle 124 is welded, and an annular magnet 125 is embedded and glued onto the baffle. An annular iron ring 126 with an iron filter screen 127 is magnetically attracted to the annular magnet 125, which can filter the air drawn in during inflation. When cleaning and maintenance are required, only a force greater than the magnetic attraction force needs to be applied to remove the annular iron ring 126 and the filter screen 127, which is very convenient. The annular iron ring 126 and the iron filter screen 127 are nickel-plated and chrome-plated, which can effectively prevent rust.

[0020] To facilitate tightening, handles 14 are fixedly installed on the outer periphery of both the mounting sleeve 11 and the internal threaded cover 13.

[0021] In use, the mounting sleeve 11 is passed through the mounting hole in the water tank wall, and the ring piece 112 is tightly attached to the outer wall and glued firmly. At this time, the end with the rubber sleeve 114 extends into the air chamber. When inflation is required, the exhaust threaded connector 121 of the annular fan housing 12 is screwed into the threaded interface 113 of the mounting sleeve 11, and the power supply of the axial flow fan 123 is turned on. After the air is filtered by the filter screen, it is blown into the air chamber of the water tank. When deflation is required, the air inlet threaded connector 122 of the annular fan housing 12 is screwed into the threaded interface 113 of the mounting sleeve 11, and the air in the air chamber is extracted by the axial flow fan 123. After inflation or deflation is completed, the annular fan housing 12 is removed, and the inner threaded cap 13 is tightened on the threaded interface 113 of the mounting sleeve 11 to ensure that the water tank does not leak. When sealing after inflation, the inner threaded cap 13 can be placed on the air inlet threaded connector 122 first, and then the axial flow fan 123 can be turned off.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model.
