Description

TECHNICAL FIELD

This new invention relates to a type of inflatable bathtubs, in particular it relates to a type of mobile inflatable bubble massage bathtub.

BACKGROUND TECHNOLOGY

As a new way of popular water massage leisure, mobile inflatable bubble massage bathtub has been appreciated and accepted by the market owing to its fast dismantling property and low price. This type of mobile inflatable bubble massage bathtub generally consists of inflatable tub body and the electric appliance box containing air pump system, filtering system, heating system and control system (including the control panel).
At present, mobile inflatable bubble massage bathtubs commonly found in the market features two structures, in one structure the electric appliance box is placed outside, as shown in FIG. 1, electric appliance box 111 is placed totally outside. Mobile inflatable bubble massage bathtub in this structure must be installed before usage through the following procedures:
1. Connect and fasten air connector 112 on electric appliance box 111 with air duct connector 122 (used for generating bubbles) on air duct 121 fixed at the bottom of inner wall of inflatable tub body 120 (air duct connector 122 is inserted through and fastened on the outer wall of inflatable tub body 120);
2. Connect and fasten water outlet connector 113, water inlet connector 114 on electric appliance box 111 which are jointly used by filtering and heating system respectively onto pool water outlet pipe connector 123 and pool water inlet pipe connector 124 (123 & 124 are inserted through and fastened onto the outer wall of inflatable tub body 120).
Furthermore, to ensure that the water will not flow into the air pump along air duct 121 when air pump is not operating, it is also necessary to set up safety air pipe, to make water detour to position higher than highest water level. For such inflatable bathtub with electric appliance box 111 totally outside, if electric appliance box 111 itself is high enough (higher than inflatable tub body 120), then it is not necessary to set up additional safety air pipes, but the height of electric appliance box 111 must be higher than inflatable tub body 120; if electric appliance box 111 itself is not high enough, then it is also necessary to set up safety air pipe at the side or top of electric appliance box 111 (not shown in the diagram), this further increases the volume of electric appliance box 111.
Inflatable bathtub in another structure features partial outside installation of the electric appliance box, shown as in FIG. 2, electric appliance box 221 is installed inside inflatable tub body 220. For inflatable bathtubs of this structure, the bubble-generating air duct 225 at the bottom of inner wall of inflatable tub body 220 directly joins with air connector on electric appliance box 221 (air connector is inserted through the inner wall of inflatable tub body 220, not shown in the diagram); water inlet and outlet openings are also deployed on the inner wall of electric appliance box 221 (water inlet and outlet openings pass through the inner wall of inflatable tub body 220, also not shown in the diagram). Therefore, it is not necessary to connect air connector with water inlet outlet connector by oneself before usage.
However, for inflatable bathtub of this structure, since electric appliance box 221 is mounted inside inflatable tub body 220, its height is certainly less than that of inflatable tub body 220, therefore it is necessary to set up extra safety air pipe 210 outside inflatable tub body 220, along with its control panel 211 and cloth cover 215 for protecting these two parts. As a result, before usage the user still needs to make necessary installation, i.e. to connect and fasten two air pipe connectors 212 and 213 of safety air pipe 210 respectively onto air duct connector 222 and 223 which extend from electric appliance box 221; and also to connect plug 214 of control panel 211 with socket 224 of electric appliance box 221.
The defects of mobile bubble massage bathtub in these two structures are:
1. In both cases users must install the bathtub before usage, which will not only bring inconvenience to usage, but also cause some hidden quality hazards owing to unskillful installation;
2. Product packaging is complicated, separate parts must be packed independently before being uniformly packaged into the whole packaging box, resulting in large packaging dimension, high transport and warehousing costs.
