Description

TECHNICAL FIELD

[0001] The utility model relates to a waterproof electric bidet. BACKGROUND

[0002] The electric bidet is a device that can be used for local cleaning of human body, which usually comprises a main machine and a water storage device, and the main machine usually comprises a machine body and components such as a water pump, a battery and a control panel arranged in the inner cavity of the machine body. The battery is used to supply power to the control panel, and the control panel controls the opening and closing of the water pump. When the water pump is turned on, it can draw water in the water storage device to the spray head and spray it out from the spray head for cleaning the human body. When the machine body is assembled with components such as the water pump, the battery and the control panel, the inner cavity of the machine body is a sealed cavity to prevent external water flow from entering the inner cavity of the machine body and causing the water pump, the battery and the control panel to be damaged by water. SUMMARY

[0003] The inventor found that although the inner cavity of the machine body of the electric bidet is a sealed cavity after the machine body is assembled with components such as the water pump, the battery and the control panel, there is still a problem that external water vapor enters the sealed cavity, and then condenses into water droplets on the surfaces of the water pump, the battery and the control panel, causing short circuit of the electric components.

[0004] After analysis, there are mainly two reasons for the external water vapor to enter the sealed cavity: one is that when the electric bidet is working, the water pump, the battery and the control panel generate heat, and the gas in the sealed cavity expands and pressurizes. At this time, some sealing rings or sealing pads used to seal the machine body to form the sealed cavity are deformed under pressure to allow the heated and expanded gas to partially leak out to release pressure. When the electric bidet stops working, the gas in the sealed cavity cools and contracts, and at this time, a certain vacuum degree is formed in the sealed cavity, and the external air containing water vapor will enter the sealed cavity through the deformed sealing ring or sealing pad. The other is that when the electric bidet is working, the water pump, the battery and the control panel generate heat, and the gas in the sealed cavity expands and pressurizes. At this time, the increased gas pressure may cause the welded part forming the sealed cavity to crack, so that the sealed cavity is no longer "sealed", and then the external air containing water vapor enters the sealed cavity.

[0005] In order to solve the above problems, the purpose of the utility model is to provide a waterproof electric bidet, which has a simple structure and can effectively prevent water vapor from entering the sealed cavity of the machine body, ensuring the reliable function of the product.
