[0001] The invention relates to the technical field of inflatable swimming pools, and in particular to an inflatable swimming pool that is convenient for drainage. Background Art

[0002] With the progress of society, individuals' requirements for the quality of life have been gradually improved. Inflatable swimming pools are light in weight and easy to carry. They can be used in a variety of occasions, such as small parks, roadsides, homes, etc., to meet the water entertainment needs of family children. There are already many ordinary inflatable swimming pools on the market, but there are still some defects in use, such as incomplete drainage, poor safety, poor flexibility, etc. In addition, due to material problems, the pool is easily damaged and water waste is also serious.

[0003] The swimming pool in the prior art is usually a fixed structure, that is, it is a whole. When it is not in use, it cannot be folded, resulting in a large space occupation. In addition, there are also some inflatable swimming pools in the prior art, but the bottom of the existing inflatable swimming pools is usually a fixed structure. Draining the swimming pool is a difficult problem. Usually, only a drainage port is opened on the side wall of the swimming pool or an enlarged drainage pipe is set on the side. However, the drainage effect is not obvious, and dirty water is easily deposited on the bottom of the pool, causing bacteria to grow and affecting the health of users.

[0004] Moreover, the existing swimming pool is flat after being inflated, and will bulge outward after being filled with water, which affects the appearance and occupies a larger area, and has certain limitations in use. When inflating the air chamber, it is necessary to manually inflate it, which is time-consuming and laborious. Using an air pump requires pulling wires, which is troublesome to operate and extremely inconvenient to use.

[0005] There is a need for a new inflatable swimming pool that is easy to use, has better drainage efficiency and is easy to inflate, which can solve the above problems. Summary of the invention

[0006] The invention provides an inflatable swimming pool with convenient drainage, and solves the problem that the existing swimming pool is not convenient to use by technically transforming the existing inflatable swimming pool equipment.

[0007] In order to solve the above technical problems, the present invention specifically adopts the following technical solutions:

[0027] like Figure 1-5 As shown, the present embodiment provides an inflatable swimming pool which is convenient for drainage, including an air chamber layer 1 and a bottom pad 2, wherein the air chamber layer 1 is surrounded into an approximate rectangle, and the two long sides of the rectangular air chamber layer 1 are recessed inwardly, and the bottom of the air chamber layer 1 is closed by the bottom pad 2 to form a pool structure, and after the air chamber layer 1 and the bottom pad 2 are filled with water, the two long sides of the air chamber layer 1 can expand outwardly to form a straight rectangular pool, and a storage chamber 3 is also provided in the air chamber layer 1, and a closing cover 4 is provided outside the storage chamber 3, and a power module 31, a control switch 32 and an air pump 33 are arranged in the storage chamber 3, and the air pump 33 is connected to the inner cavity of the air chamber layer 1 through an inflation connecting pipe 34, and the control switch 32 can control the air pump 33 to be turned on or off.

[0028] The thickness of the air chamber layer 1 is increased from the traditional 0.28 mm to 0.40 mm. The increased thickness of the product also improves the product quality, making the product less prone to damage and more durable.

[0029] Further, in order to facilitate the installation of the power module 31, the control switch 32 and the air pump 33, the air chamber layer 1 includes an upper air chamber 11, a middle air chamber 12 and a lower air chamber 13, and the outer walls of the upper air chamber 11, the middle air chamber 12 and the lower air chamber 13 are all provided with an air inflating nozzle 5, and the storage chamber 3 is arranged at the lower air chamber 13. The power module 31 can use a rechargeable battery, which is convenient for installation, disassembly and replacement. The air inflating nozzle 5 is respectively arranged on the upper side of the outer wall of the upper air chamber 11, the middle air chamber 12 and the lower air chamber 13.

[0030] Furthermore, in order to enable the air pump 33 to fill up the upper air chamber 11, the middle air chamber 12 and the lower air chamber 13 at the same time, an upper air vent 14 is opened between the upper air chamber 11 and the middle air chamber 12, and a middle air vent 15 is opened between the middle air chamber 12 and the lower air chamber 13. The air pump 33 in the storage chamber 3 is connected to the lower air chamber 13 through the lower air port 341 set at the end of the inflation connecting pipe 34.

[0031] Furthermore, in order to obtain a better user experience, the air inflation nozzle 5 can also be used for inflation and deflation. The air inflation nozzle 5 includes a base 51, a rubber protective cover 52, a connecting tie 53, a middle plug 54 and a top plug 55. The base 51 is provided with a rubber protective cover 52, and a first air vent 56 is opened in the middle of the rubber protective cover 52. The upper periphery of the first air vent 56 is also connected to the middle plug 54 and the top plug 55 through the connecting tie 53. The lower end of the middle plug 54 can close the first air vent 56. A second air vent 57 is also opened on the upper part of the middle plug 54. A one-way valve 58 is arranged between the second air vent 57 and the bottom of the middle plug 54. The lower end of the top plug 55 can close the second air vent 57. When using a larger-caliber inflator, the middle plug 54 is opened to directly inflate the first vent hole 56. After the middle plug 54 is covered, a smaller-caliber inflator can be used to inflate the air chamber from the second vent hole 57. Due to the design of the one-way valve 58, air cannot escape from the second vent hole 57 in the opposite direction. The inflator nozzle 5 can also sink the middle plug 54 and the top plug 55 into the rubber protective sleeve 52 after being pressed. At this time, the outer surface of the inflator nozzle 5 is flush with the outer wall of the air chamber layer 1.

[0032] Furthermore, in order to achieve the control effect of the one-way airflow passing through the one-way valve 58, the one-way valve 58 includes an elastic valve sheet 581 and a limit block 582. The middle plug 54 has a mounting hole 541 at the bottom center, and a plurality of through holes 542 are arranged around the mounting hole 541. The middle part of the elastic valve sheet 581 protrudes through the mounting hole 541 and is connected to the limit block 582 in the second air hole 57 of the middle plug 54. The limit block 582 is used to prevent the elastic valve sheet 581 from detaching from the middle plug 54. The elastic valve sheet 581 can be pushed by the airflow to open or close the through hole 542.

[0033] Furthermore, in order to obtain better comfort, the bottom pad 2 is divided into three layers, which are the upper PVC layer 21, the middle EVA sponge layer 22 and the lower PVC layer 23 from top to bottom. EVA sponge is a kind of polyolefin plastic foamed, also known as foam, which does not contain any toxic substances harmful to the human body, and EVA sponge is flexible, light, high in density and elastic, and can be used as a cushioning material to protect the product to better absorb and disperse external impact force. At the same time, EVA sponge has a series of excellent use characteristics such as heat preservation, moisture resistance and corrosion resistance. Using EVA sponge as the bottom layer of the air cushion has a better touch and is more comfortable to step on.

[0034] Furthermore, in order to obtain better drainage efficiency, the base pad 2 is provided with an openable and closable drainage port 24 , and the drainage port 24 is also connected to a drainage pipe 25 provided at the bottom of the base pad 2 , and the drainage pipe 25 extends to the outside of the air chamber layer 1 .

[0035] Furthermore, in order to enrich the playing methods of the swimming pool, matching inflatable toys, such as inflatable dolls, slides, parasols, swimming rings and other inflatable toys, can be provided on the upper end of the swimming pool air chamber, making it more interesting to play in the swimming pool.

[0036] In this embodiment, the side wall of the pool is designed to be concave inwards. After being filled with water, the side wall of the pool will expand to form a flat square. The air nozzle design of this embodiment is higher than the pool air nozzle of the existing design. The existing design of the air nozzle 5 will pop out due to water pressure after being filled with water. The design is higher and is not easy to pop out after pressing the air chamber. In this embodiment, an electric air pump 33 is arranged inside the air chamber. By installing a power supply component, the air pump 33 can be automatically inflated to meet the needs of outdoor use. The air cushion bottom layer of this embodiment is a three-layer design. The existing design is a single-layer PVC material. The present invention is sequentially arranged from top to bottom with an upper PVC layer, a middle EVA sponge layer, a lower PVC layer, and a middle EVA sponge layer. EVA sponge is a polyolefin plastic foamed, also known as foam. It does not contain any toxic substances harmful to the human body. EVA sponge is flexible, light, high in density, and elastic. It can be used as a buffer material to protect the product to better absorb and disperse external impact force. At the same time, EVA sponge has a series of excellent use characteristics such as heat preservation, moisture resistance, and corrosion resistance. Using EVA sponge as the bottom layer of the air cushion provides a better touch and more comfortable stepping.
