[0002] A foot bath basin, also known as a foot bath device, is a container used for foot washing and massage. It is generally divided into two types. One is an electric appliance with a plastic basin with heat preservation and massage functions. The other is a single-function barrel made of wood or plastic. Foot bath is one of the traditional Chinese medicine therapies, and has certain physiotherapy and health care effects. With the improvement of living standards, it has gradually been accepted and used by people. It generally has the functions of heating, vibration massage, and some also have water flow impact (surfing), bubbles, ozone, infrared, magnetic therapy, etc. Some foot baths have a barrel with a folding structure, such as the Chinese patent document No. 201420564562.4, granted on February 18, 2015, with the utility model name "folding foot bath device"; and the Chinese patent document No. 202022287587.2, granted on August 27, 2021, with the utility model name "folding foot bath basin for warming feet". However, the above products and similar products have few charging functions and shower type spraying functions. SUMMARY

[0003] To overcome the above-mentioned shortcomings, the utility model aims to provide a charging type folding foot bath basin to solve the technical problems of the lack of charging and shower type spraying functions in existing similar foot bath products, the inconvenience of use after power failure, and the lack of heat preservation structure design, which results in poor heating safety. Specifically, the technical solution is as follows.

[0004] A charging type folding foot bath basin, the barrel body of the foot bath basin is provided with a control circuit board and corresponding pipelines in the bottom, a mesh cover platform is protruded in the middle of one side of the inner bottom of the barrel body, a gas pump is arranged in the mesh cover platform, a cavity opening sealing partition plate is arranged at the bottom of the inner chamber of the mesh cover platform, a switch button is arranged at one side of the bottom of the barrel body, and the switch button and the gas pump are connected with the control circuit board through lines; the structure design points of the barrel body are that a USB socket is arranged at one side of the bottom of the barrel body, a battery protection plate and a waterproof battery box are arranged in the bottom of the barrel body, a charging lithium battery is arranged in the waterproof battery box, and the waterproof battery box, the battery protection plate and the USB socket are connected with the control circuit board through lines. Thus, the foot bath basin is powered by the charging lithium battery, which is convenient for use when the plug is pulled out.

[0005] A water pump is installed at the bottom of the bucket. The water pump's inlet is connected to a water inlet hole at the bottom of the bucket via a pipe. A filter screen is installed at the water inlet hole. The water pump's outlet is connected to a water outlet hole at the bottom of the bucket via a pipe. A shower spray rod is inserted into the outlet hole. The shower spray rod is located in the middle of the other side of the bottom of the bucket. When in use, the shower spray rod is slightly lower than the bucket opening. The shower spray nozzles of the shower spray rod spray water in an umbrella shape. The water pump is connected to a control circuit board via wiring. The top of the shower spray rod has a mushroom-shaped head to facilitate umbrella-shaped water spray during use.

[0006] A one-way valve is provided at the connection between the water outlet at the bottom of the barrel and the shower rod. The one-way valve is fixedly installed in the nozzle of the shower rod or in the water outlet at the bottom of the barrel. When the shower rod is inserted into the water outlet at the bottom of the barrel, the one-way valve opens automatically.

[0009] The insulating heating wire is attached and fixed to the bottom of the bucket and is wound in a serpentine shape. The insulating heating wire is connected to the control circuit board via wiring. Compared with the heating tube, the above-mentioned insulating heating wire is more efficient, mainly for the insulation of the plastic bucket and heat conduction, eliminating the need to heat the water in the bucket through the heating tube at the bottom of the bucket.

[0010] A heating plate, which is a PTC heater, is installed inside the mesh cover platform at the bottom of the barrel. The heating plate is connected to a control circuit board via wiring. An open mesh cover is provided on one side of the mesh cover platform. This structure facilitates cleaning of the inside of the mesh cover platform and the area around the air pump or heating plate within it.

[0011] The bottom of the barrel is equipped with a light panel, a bubble strip, and / or rollers. A motor may be installed on the protrusion at the bottom of the barrel on one side of the rollers. The motor, light panel, and bubble strip are connected to the control circuit board via wiring, and the bubble strip is connected to the air pump via a pipeline.

[0012] The bucket body includes a telescopic basin, an upper base, and a lower cover. The bottom opening of the telescopic basin is ultrasonically fused and sealed to the top edge of the upper base. The inner diameter of the top opening of the telescopic basin is larger than that of the bottom opening, allowing it to fold and extend. The lower cover is located at the bottom of the upper base, and support feet are located at the bottom corners of the lower cover. The USB port and the power button are located on one side of the connection between the upper base and the lower cover. A water-blocking cover is located on one side of the top opening of the telescopic basin. When folded, the height of the basin opening is slightly higher than the height of the mesh cover platform. The above is a specific structural embodiment of the foldable bucket body.

[0013] The foot bath includes a remote control, which is either attached to or magnetically attached to the water-retaining cover. Specifically, the water-retaining cover has a slot for the remote control, or the water-retaining cover has a magnet, and another magnet is located at the bottom of the cover corresponding to the remote control.

[0014] This utility model has a reasonable structural design, is easy to assemble and use, has good sealing and safety, and provides good effects in foot warming, lighting, massage, and bubble function. In particular, it is convenient to use after charging and has added a shower-style spray function.
