The flexible layer S can be unfolded or folded longitudinally to move the rigid upper edge 13 and rigid bottom 11 of the collapsible bathtub 10 longitudinally away from or toward each other so that the collapsible bathtub 10 can be in an unfolded state, in which the legs 14 can be unfolded to support the collapsible bathtub 10; the collapsible bathtub 10 may also be in a collapsed condition in which the feet 14 are rotatable and receivable under the rigid base 11.

In other embodiments, the folding peripheral portion 12 may further have more than one flexible layer S, such as a tub with a tub body and supporting feet capable of stretching and retracting synchronously, which are provided in the patent with the publication number CN219249993U, and the technical solution of having two flexible folding layers is disclosed in the specification, so that the tub body can be at two different heights. When there is more than one flexible layer S, the collapsible tub 10 can be at a variety of different heights to meet the bathing needs of infants of different sizes.

As shown in fig. 2 and 3, the folding bathtub 10 according to the present embodiment has a substantially rectangular parallelepiped shape, so that the length of the rigid bottom 11 is greater than the width thereof. The sheet-shaped supporting frame 30 is installed at the bottom of the folding bathtub 10, and its length is also longer than its width, and its length direction is consistent with the length direction of the folding bathtub 10, i.e., the length direction of the hard bottom 11. Six load cells 20 are arranged in three pairs in a dispersed manner in a sheet-like support frame 30.

When an infant enters the bathtub, the infant is usually positioned in the middle of the bathtub, the weighing sensors 20 are arranged in the thin plate-shaped supporting frames 30, and the thin plate-shaped supporting frames 30 are arranged at the bottom of the folding bathtub 10, so that the weight of the infant can be uniformly and completely conducted to each weighing sensor 20 through the thin plate-shaped supporting frames 30, and the technical problem of inaccurate weighing caused by uneven weight distribution due to concave deformation of the bottom of the bathtub and even partial weight dispersion of the ground below the bottom of the bathtub due to excessive concave sinking of the bottom of the bathtub in the prior art is solved.

In addition, since the load cells 20 are arranged in the thin plate-shaped supporting frame 30, the distance between the load cells 20 can be shortened, the loss between the wires can be reduced, and the weighing accuracy can be further improved.

An accommodating cavity is formed between the inner side of the sheet-shaped supporting frame 30 and the hard bottom 11 of the folding bathtub 10, and is used for accommodating a control circuit board (not shown), an inner lead (not shown) and a power supply battery B. The six weighing sensors 20 are connected with the control circuit board through inner leads, and the power supply battery B supplies power for the control circuit board and the display screen 40. Therefore, the control circuit board, the inner lead, the power supply battery B and other electrical components are arranged in the accommodating cavity, and the function of protecting the electrical components is achieved.

Specifically, as shown in fig. 4, in the present embodiment, the sheet-like support frame 30 includes a frame bottom wall 31 and an outer peripheral wall 32, the frame bottom wall 31 and the outer peripheral wall 32 form a concave cavity 33, and the control circuit board, the inner leads, and the power supply battery B are provided in the concave cavity 33. The structural design enables the whole sheet-shaped supporting frame 30 to be flatter, and the electrical elements are arranged in the concave cavities 33, so that the infant is prevented from being received by the upper hard bottom 11 and the lower bottom surface to be extruded bidirectionally during bath.

As shown in fig. 3 and fig. 4, the bottom of the sheet-shaped support frame 30 is provided with a battery slot 34 for installing the power supply battery B, and the battery slot 34 extends inwards into the concave cavity 33, so that a user can replace the power supply battery B through the bottom of the sheet-shaped support frame 30, but the space position of the power supply battery B extends into the concave cavity 33, so that firstly, the power supply battery B can be conveniently electrically connected with an inner wire in the concave cavity 33, and secondly, the power supply battery B is prevented from protruding out of the bottom surface of the sheet-shaped support frame 30 and being easy to collide or squeeze.

As shown in fig. 2 to 4, the control circuit is connected to the display 40 through an external wire W extending along the outer wall of the folding bathtub 10. Specifically, a first wire through hole K1 is formed below the display screen 40 on the hard upper edge 13, a second wire through hole K2 is formed on the side surface of the sheet-shaped support frame 30, and the outer wire W passes through the second wire through hole K2 and the first wire through hole K1 to be connected with the display screen 40.

The outer surface of the hard bottom 11 is provided with a wire groove C on the wiring path of the outer wire W, and in this embodiment, the hard bottom 11 includes a tub bottom 11a and a peripheral side plate 11b integrally extending upward from the periphery of the tub bottom 11a, and the tub bottom 11a and the peripheral side plate 11b are in arc transition, and the wire groove C extends from the outer surface of the tub bottom 11a to the outer surface of the peripheral side plate 11b, also in arc transition. A portion of the outer wire W is embedded in the wire groove C and passes over the flexible layer S into the first wire via K1.

Firstly, the periphery of the basin bottom plate 11a of the hard bottom 11 is integrally extended upwards to form a peripheral plate 11b, so that the whole hard bottom 11 has higher mechanical strength and can better support the weight of bath water and infants; secondly, a wire groove C is arranged on the wiring path of the outer wire W, and a part of the outer wire W is embedded in the wire groove C, so that the outer wire W can be fixed on the folding bathtub 10, the outer wire W is prevented from being hooked or torn off due to the fact that the outer wire W is hung outside the folding bathtub 10 at will, and meanwhile, the guiding and positioning effects are achieved on the trend of the outer wire W; again, the outer wire W passes over the flexible layer S into the first wire through hole K1 so as not to interfere with the unfolding and folding of the folding bathtub 10.

As shown in fig. 3, six placement grooves 35 are formed in the bottom of the sheet-shaped support frame 30, six weighing sensors 20 are respectively installed in the six placement grooves 35, and an outer cover 21 is arranged outside each weighing sensor 20 so as to cover the outer sides of the weighing sensors 20, so that a certain fixing and protecting effect is achieved. When the folding bathtub 10 is placed on the ground, the weight of the infant is conducted to the thin plate-shaped supporting frame 30 through the hard bottom 11 and then to the load cell 20, and the outer cover 21 contacts the ground below, and the ground gives an upward reaction force to the load cell 20 through the outer cover 21, so that the load cell 20 is balanced in the vertical direction, thereby performing pressure sensing. Preferably, the bottom of the outer cap 21 is convexly provided with a bottom pad 22, which serves to buffer and strengthen the structural strength of the outer cap 21.

As shown in fig. 3 and 5, it is preferable that the bottom of the folding bathtub 10 is convexly provided with a reinforcing rib 15, and the lower surface of the reinforcing rib 15 exceeds the lower surface of the thin plate-shaped supporting frame 30, but does not exceed the lower surface of the outer cover 21, so that auxiliary supporting protection is provided for the bottom of the folding bathtub 10 on the premise of ensuring that the load cell 20 can be stressed and balanced, on the one hand, the structural strength is increased, and on the other hand, the electric components inside the thin plate-shaped supporting frame 30 are prevented from being damaged by excessive extrusion.

As shown in fig. 4, in the present embodiment, the sheet-like support frame 30 includes a running portion 36 extending in the longitudinal direction of the hard bottom surface 11, and six mounting portions 37 uniformly arranged in three pairs on both sides of the running portion 36, and six insertion grooves 35 are respectively opened at bottoms of the six mounting portions 37, so that six load cells 20 are respectively mounted in the six mounting portions 37. The control circuit board and the power supply battery B are mounted in the wiring portion 36, and the inner lead wires are mainly wired in the wiring portion 36 except for the entry mounting portion 37 electrically connected with the load cell 20. The layout arrangement can lead the inner lead to be more regular, and prevent the loss caused by lead winding.

Further, preferably, when the leg 14 is received under the hard bottom 11, the leg 14 avoids the mounting portion 37, thereby preventing the received leg 14 from being pressed against the load cell 20 or the outer cover 21.

As shown in fig. 6, the inner surface of the rigid bottom 11 of the folding bathtub 10 is provided with at least one height scale line L, in this embodiment, two height scale lines L including a centimeter scale line and an inch scale line are provided, but of course, in other embodiments, the height scale line and the inch scale line may be adjusted according to the unit of measurement of the place of sale, and the centimeter scale line and the inch scale line are parallel to each other and horizontally extend along the length direction of the rigid bottom 11 of the folding bathtub 10. Therefore, when the infant takes a bath, weighing and height measurement can be simultaneously carried out, so that the growth condition of the infant can be concerned at any time.

It should be noted that, different shapes and sizes of the folding bathtub can be provided with different numbers of weighing sensors, and the weighing sensors correspond to the thin plate-shaped supporting frames with different shapes and structures. For example, in the case of a small size of the folding bathtub or a substantially cubic overall shape, only four load cells may be provided and distributed in two pairs within the sheet-like support frame. The sheet-like support frame may be provided with the wiring portion and the two mounting portions uniformly arranged on both sides of the wiring portion in two pairs similarly to the present embodiment, but of course, the sheet-like support frame may be provided in a cross radiation shape or the like.
