Description

Technical Field

[0001] This invention relates to a children's bathing product, specifically a children's bathing device. Background Technology

[0002] While some specialized childcare devices, such as baby bathtubs and infant bath chairs, exist in the current technology, these products generally suffer from limitations in functionality, ease of cleaning, and inadequate wastewater treatment. For example, some baby bathtubs only provide basic support and lack independent showering devices, forcing parents to use a ladle to pour water when bathing their children. This is cumbersome and inefficient, and fails to effectively address the collection and discharge of bathing wastewater, affecting the cleanliness and safety of the environment.

[0003] The prior art CN120732300A discloses a child care device that is easy to clean. Specifically, it discloses a child care device with a support and a shower device. However, the support of this device has a small area and lacks a structure to prevent children from rolling over and falling. It does not leave enough space for children to move their bodies. For children who are prone to moving around during the bath, there may be a risk of falling. If a safety belt is used to restrain them, the support does not leave enough space for children to roll over and tilt to the side, making it difficult to clean the back area. Summary of the Invention

[0004] In response to the aforementioned problems of existing child care devices, such as insufficient space for movement due to their small size and lack of structures to prevent children from rolling and falling, the technical solution adopted by this invention is as follows: A child bathing device includes a support bracket and a water treatment unit mounted on the support bracket. The support bracket includes a support member and supporting legs. The water treatment unit includes a hot water supply device and a wastewater collection tank. The water treatment unit is installed below the support member. The support member includes a support surface for a child to lie down and a guardrail structure for preventing the child from falling. The maximum length 'a' of the support surface ranges from 50 to 85 cm, and the maximum width 'b' of the support surface ranges from 20 to 50 cm. The drain outlet of the support member is located above the inlet of the wastewater collection tank. The support surface has a water-gathering structure near the drain outlet. The guardrail structure has a strap slot for a safety belt to pass through.

[0005] As described above, in a child bathing device, the supporting surface is provided with a water-gathering structure near the drain outlet.

[0006] As described above, in a child bathing device, the guardrail structure surrounds the outer periphery of the supporting surface and extends upward. The guardrail structure is composed of a first guardrail, a second guardrail, and a third guardrail. The first guardrail is located on the side closer to the drain outlet. The extension height of the second guardrail and the extension height of the third guardrail are both greater than the extension height of the first guardrail.

[0007] In the child bathing device described above, the second guardrail is located between the first guardrail and the third guardrail. The second guardrail extends along the length of the supporting surface and is disposed on both sides of the supporting surface. At least two of the guardrail grooves are spaced apart along the length of the second guardrail.

[0008] As described above, in a child bathing device, the support frame includes a plurality of support rods, and the support member includes a rod mounting part for mounting the support rods. The rod mounting parts are respectively located below the junction between the first guardrail and the left side rail, and below the junction between the second guardrail and the third guardrail.

[0009] As described above, in a child bathing device, the support frame includes a main unit bracket for placing the water treatment main unit, the main unit bracket being installed between adjacent support rods.

[0010] As described above, in a child bathing device, the support rod includes a first rod segment and a second rod segment. The first rod segment is located between the rod mounting portion and the main support bracket and extends in a direction perpendicular to the support surface. The second rod segment extends from the first rod segment downwards at an angle away from the main support bracket.

[0011] As described above, a children's bathing device includes a water tank located inside the water treatment unit, a shower head connected to the water tank via a water hose, a pump for supplying water to the shower head, and a heater for heating the water source.

[0012] In the child bathing device described above, the maximum length 'a' of the supporting surface ranges from 50 to 85 cm, and the maximum width 'b' of the supporting surface ranges from 20 to 50 cm.

[0013] A child bathing device includes a support bracket and a water treatment unit mounted on the support bracket. The support bracket includes a support member and supporting legs. The water treatment unit includes a clothing storage box and a wastewater collection box. The water treatment unit is installed below the support member. The support member includes a support surface for a child to lie down and a guardrail structure for preventing the child from falling. The maximum length 'a' of the support surface ranges from 50 to 85 cm, and the maximum width 'b' of the support surface ranges from 20 to 50 cm. The drain outlet of the support member is located above the inlet of the wastewater collection box.

[0014] The beneficial effects of this invention are as follows: This invention improves the structure of the support component, expanding the usable area of ​​the support surface to allow children to fully bathe and wash their bodies. It also makes it convenient for children to tilt their bodies to wash different parts of the support surface. At the same time, the support component adopts a guardrail structure to prevent children from slipping, thereby improving safety during use. The wastewater tank can effectively collect wastewater flowing through the support component, avoiding slippery ground and ensuring a clean and safe use environment. The support legs are set up so that users do not need to squat or bend down, allowing them to bathe and care for children upright, thus achieving a more convenient, efficient and safe child care experience.

[0023] Example 1 Figures 1 to 5 This embodiment provides a child bathing device, including a support bracket 1200 and a water treatment unit 3400 mounted on the support bracket 1200. The support bracket 1200 includes a support member 1 and a support leg 2. The water treatment unit 3400 includes a hot water supply device 3 and a wastewater collection tank 4. The water treatment unit 3400 is mounted below the support member 1. The support member 1 includes a support surface 11 for children to lie down and a guardrail structure 12 for preventing children from falling. The maximum length a of the support surface 11 is in the range of 50-85cm, and the maximum width b of the support surface 11 is in the range of 20-50cm. The drain outlet 13 of the support member 1 is correspondingly located above the water inlet 41 of the wastewater collection tank 4. The support surface 11 has a water collection structure 14 near the drain outlet 13. The guardrail structure 12 has a safety belt slot 124 for the safety belt to pass through.

[0024] Specifically, in this embodiment, the support bracket 1200 is a support frame structure of the children's bathing device used to install the water treatment unit 3400 and provide stable support for children's bathing. The support member 1 is located at the top of the support bracket 1200 and serves as an activity platform for children to lie down, tilt, bathe, and dress. The middle area of ​​the support member 1 is a support surface 11 for children's activities. The support surface 11 can be a planar structure or a curved structure. The guardrail structure 12 is a bib structure that surrounds the outside of the support surface 11 to form a protective ring. The water treatment unit 3400 is the main module of the children's bathing device used to supply hot water and treat wastewater. The hot water supply device 3 serves as the water... The water treatment unit 3400 is an actuator for storing, supplying, and heating water. The hot water supply device 3 includes a heater for heating the water, a temperature sensor for detecting the water temperature, and a thermostat for regulating the water temperature. The wastewater collection tank 4 serves as a storage tank structure for the water treatment unit 3400 to collect, discharge, or clean the water. The water treatment unit 3400 is installed below the support 1, which also facilitates the collection of bathing wastewater flowing from the drain outlet 13 by the wastewater collection tank 4. The wastewater collection tank 4 is installed in a side-pull-out manner below the water treatment unit 3400 at the position corresponding to the drain outlet 13 on the support 1. The drain outlet 13 preferably extends into the inlet 41 to reduce wastewater splashing to the outside. To further improve the safety of children during bathing, the support member 1 in this embodiment has a surrounding guardrail structure 12 on the outer periphery of the support surface 11. The guardrail structure 12 curves and extends from the inside out and from the bottom up to form a guardrail enclosure, so as to prevent children from accidentally slipping when lying down, turning over, or tilting to the side on the support surface 11. The safety belt slot 124 can be a long slot or a rectangular slot to facilitate the user to wear a safety belt for children. The guardrail structure 12 and the support surface 11 are connected by a smooth curved surface at the junction, so that water droplets on the inside of the guardrail structure 12 can slide off and gather at the drain outlet 13 for children's bathing. During the process, the wastewater accumulated in the support 1 is guided by the water collection structure 14 and flows to the drain outlet 13, which is beneficial to the water-draining effect of the support 1. In order to expand the support area of ​​the support surface 11 for children to play, the vertical projection area e of the support surface 11 facing the ground is greater than the vertical projection area f of the water treatment host 3400 facing the ground. The maximum length a of the support surface 11 is in the range of 50-85cm, and the maximum length a is preferably 75cm or 80cm. The maximum width b of the support surface 11 is in the range of 20-50cm, and the maximum width b is preferably 40cm or 45cm, so as to meet the common body shape of children aged 0-3 years who lie down or tilt to the side.

[0025] Before use, a certain amount of water can be injected into the hot water supply device 3 in advance to heat the water. Alternatively, an external household water source can be connected, or a more powerful heater can be selected to heat the water immediately during bathing to meet the need for hot water supply during the bathing process. During use, the user places the child on the support surface 11 of the support 1 and uses the hot water supplied by the hot water supply device 3 to wash the child's body. This allows the user to perform different body parts such as washing the buttocks, back, and limbs. Wastewater generated during the washing process flows from the support surface 11 through the drain outlet 13 to the inlet of the wastewater collection tank 4 below. After the child is washed, the child can dress on the support 1 without leaving the bathroom, thus avoiding the child getting cold during the transfer. After the child is dressed and leaves, the user can remove the wastewater collection tank 4 to empty and clean the bathing wastewater inside, preventing the wastewater from flowing onto the ground and affecting the surrounding environment.

[0026] This embodiment improves the structure of the support component 1, expanding the usable range of the support surface 11 so that children can fully wash and bathe their bodies on it. It also makes it convenient for children to tilt their bodies to wash different parts of the support surface 11. At the same time, the support component 1 also adopts a guardrail structure 12 to prevent children from slipping and improve safety during use. The wastewater collection tank 4 can effectively collect wastewater flowing through the support component 1, avoiding slippery ground and ensuring a clean and safe use environment. The support legs 2 do not require the user to squat or bend down, allowing the user to bathe and care for children upright, thus achieving a more convenient, efficient and safe child care experience.

[0027] Furthermore, as a preferred embodiment of this solution and not a limitation, the water-collecting structure 14 is inclined towards the drain outlet 13 from the outside in and from top to bottom. Wastewater accumulated in the support 1 during the child's bathing process is guided by the water-collecting structure 14 and flows to the drain outlet 13, which is beneficial to the water-draining effect of the support 1, reduces the amount of sewage accumulated on the support surface 1, prevents children from soaking in water for a long time, and also helps children change clothes later. The drain outlet 13 is equipped with a mesh grid structure, preferably a "well" type grid structure. The mesh grid structure has several spaced drainage screen holes, which not only ensures that sewage is discharged smoothly, but also prevents children's hands and feet from accidentally getting stuck in the drain outlet 13, and also prevents some children's clothes, ornaments, and bath utensils from accidentally falling into the drain outlet 13, making it convenient for users.

[0028] Furthermore, as a preferred embodiment of this solution, and not a limitation thereof, the guardrail structure 12 surrounds the outer periphery of the support surface 11 and extends upward. The connection and intersection between the guardrail structure 12 and the support surface 11 adopts a smooth arc-shaped surface structure for transition, which facilitates the cleaning of accumulated sewage and also helps users to move and store the support component 1. The guardrail structure 12 is composed of a first guardrail 121, a second guardrail 122, and a third guardrail 123. The first guardrail 121 is located on the side of the support component 1 closer to the drain outlet 13, the third guardrail 123 is located on the side of the support component 1 away from the first guardrail 121, and the second guardrail 122 is located between the first guardrail 121 and the third guardrail 123. When washing a child's buttocks, the child's head is preferably placed on the support surface 11 near the third guardrail 123, and the child's feet are preferably placed on the first guardrail 121, so that the child's buttocks can be smoothly placed near the drain outlet 13 for easy washing. When cleaning the child's head, the child's feet are preferably placed on the support surface 11 near the third guardrail 123, and the child's head is preferably placed near the drain outlet 13. This allows the child's head to be positioned smoothly near the drain outlet 13, facilitating the removal of foam from the child's head. To ensure that the child's feet can easily extend beyond the support 1 when cleaning the buttocks, so that the buttocks are positioned within the drain outlet 13, the extension heights of the second guardrail 122 and the third guardrail 123 are both greater than the extension height of the first guardrail 121. The connection between the first guardrail 121 and the second guardrail 122 uses a smooth arc-shaped surface structure for transition, as does the connection between the second guardrail 122 and the third guardrail 123. This facilitates the removal of accumulated wastewater and also helps users move and store the support 1.

[0029] Furthermore, as a preferred embodiment of this solution and not a limitation, the second guardrail 122 extends along the length of the supporting surface 11 and is distributed on both sides of the supporting surface 11. To facilitate the use of a seat belt on the supporting member 1, the second guardrail 122 has a seat belt slot 124 for the seat belt to pass through. The seat belt slot 124 can be a long slot or a rectangular slot. Preferably, the second guardrail 122 on one side has two or more seat belt slots 124. Preferably, the second guardrail 122 on both sides of the supporting surface 11 has two or more seat belt slots 124 symmetrically arranged. The seat belt slots 124 can be spaced apart along the length or extension direction of the second guardrail 122 so that the user can choose different positions to put on the seat belt according to the washing and care situation or the size of the child.

[0030] Furthermore, as a preferred embodiment of this solution and not a limitation, the top of the second guardrail 122 has a storage rack hole 125 for installing an external storage rack. The user can select a suitable storage rack and install it on the support 1 through the storage rack hole 125 to place bath products such as shower gel, shampoo, brushes, and soap, making it convenient for the user to use them at any time.

[0031] Furthermore, as a preferred embodiment of this solution and not a limitation, the support frame 2 includes a plurality of support rods 21. The support rods 21 are used to support the stability of the support member 1 when placed on the ground. The support member 1 includes a rod mounting part 15 for mounting the support rods 21. The rod mounting part 15 extends from the bottom of the support member 1 toward the ground as a sleeve structure. The inner diameter of the rod mounting part 15 is adapted to the outer diameter of the end of the support rod 21. The support rods 21 are preferably respectively located at the corner positions near the outer side of the bottom of the support member 1. Specifically, the rod mounting parts 15 are respectively located below the junction between the first guardrail 121 and the left side rail, and below the junction between the second guardrail 122 and the third guardrail 123. Distributing them at the corner positions as support points helps to improve the landing stability of the support frame 2 and avoids tipping over due to the center of gravity of the support member 1 being on the side.

[0032] Furthermore, as a preferred embodiment of this solution and not a limitation, the support rod 21 includes a first rod segment 211 and a second rod segment 212. The first rod segment 211 is located between the rod mounting part 15 and the main support 22 and extends in a direction perpendicular to the support surface 11. The second rod segment 212 extends from the first rod segment 211 in a downward direction away from the main support 22. The outwardly inclined second rod segment 212 can increase the distance between adjacent landing points of the support rod 21, improve the stability of the overall structure on the ground, and prevent tipping. Since there is an open support structure in the shape of an "eight" between the two adjacent support rods 21 below the first guardrail 121, when the user stands in front of the child bathing device to bathe the child, the second rod segment 212 of the support rod 21 can form a support and avoidance space to avoid the user's feet. The user's toes can be inserted into this support and avoidance space, so that the user's body can be closer to the support 1, so as to facilitate the operation of the hands during the child bathing process.

[0033] Furthermore, as a preferred embodiment of this solution and not a limitation, to facilitate the placement of the water treatment unit 3400, the support frame 2 includes a main unit bracket 22 for placing the water treatment unit 3400. The main unit bracket 22 is installed between adjacent support rods. The main unit bracket 22 consists of a straight pipe, a main unit mounting frame, and an adapter. The adapter is installed at the corner intersection between the first rod segment 211 and the second rod segment 212 of the support rod 21. The adapter has two sleeve structures with different orientations. The straight pipe is connected to the sleeve structure of the adapter and placed between adjacent support rods 21 to form a straight pipe enclosure frame that reinforces the support rods 21. After the main unit mounting frame is installed on the straight pipe enclosure frame, the water treatment unit 3400 can be installed on the main unit mounting frame to fix the position of the machine body.

[0034] Furthermore, as a preferred embodiment of this solution and not a limitation, the hot water supply device 3 includes a water tank 31 housed within the water treatment unit 3400, a shower head 32 connected to the water tank 31 via a water hose, a pump 33 for supplying water to the shower head 32, and a heater 34 for heating the water source. The water tank 31 is used by the water treatment unit 3400 to store water to be heated. Users can remove the water tank 31, fill it with water from the shower room, and then place it back into the water treatment unit 3400 for children's bathing, or fill the water tank 31 at home beforehand and take it outdoors for children's bathing. The water tank 31 has a water storage cavity and a flip-top cover to ensure it can be sealed after being filled with water. The shower head 32 is a shower head structure provided by the water treatment unit 3400 for users to spray and wash children. To ensure a suitable water temperature and avoid scalding, the water tank 31 is equipped with a temperature sensor for detecting the water temperature and a water level sensor for detecting the water level. The control panel of the bathing device is equipped with a thermostat for adjusting the water temperature of the water tank 31 and a switch button for user operation. The user starts the children's bathing device by pressing the switch button. The heater 34 heats the water stored in the water tank 31. The temperature sensor collects the water temperature and feeds it back to the thermostat, so that the water is heated to the preset temperature and then enters a constant temperature or stops heating. During the bathing process, the temperature sensor also continuously monitors the water temperature and adjusts the heater 34 in conjunction with the thermostat to prevent the water temperature from dropping and to prevent the child from getting cold. The user turns on the pump 33 by pressing the switch button. The pump 33 pumps the heated water from the water tank 31 to the shower head 32. The shower head 32 sprays the stored water to the child for bathing, achieving the effect of water spraying. When the water level inside the water tank 31 drops to the preset position, the water level sensor is triggered to disconnect the heater 34 to stop heating the stored water to prevent dry burning. The children's bathing device can be equipped with an independent power supply for use, or it can be connected to the household power grid of the bathroom for use.

[0035] Example 2 Figures 1 to 5This embodiment provides a child bathing device, including a support bracket 1200 and a water treatment unit 3400 mounted on the support bracket 1200. The support bracket 1200 includes a support member 1 and support legs 2. The water treatment unit 3400 includes a clothing storage box 5 and a wastewater collection box 4. The water treatment unit 3400 is mounted below the support member 1. The support member 1 includes a support surface 11 for a child to lie down and a guardrail structure 12 for preventing the child from falling. The vertical projected area e of the support surface 11 is larger than the vertical projected area f of the water treatment unit 3400. The drain outlet 13 of the support member 1 is correspondingly located above the water inlet 41 of the wastewater collection box 4. Compared to Embodiment 1, the children's bathing device in this embodiment can eliminate the hot water supply device 3. Users can use external shower tools or external shower systems to supply water for children's bathing. The hot water supply device 3 is replaced by a clothing storage box 5 in the original water tank 31 position. The clothing storage box 5 has a storage cavity and a flip-top lid, which can store the clothes that the child will use or the clothes that need to be washed, to prevent the child's clothes from getting wet during the bathing process. It can also put the user's jewelry on their hands and body into the clothing storage box 5 to prevent the jewelry from getting wet or affecting the child's bathing. This makes it convenient for users to use the children's bathing device in bathrooms without clothes racks or outdoors.
