Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, and in particular to an ultrasonic hand cleaning device for children's health protection. Background Technology

[0002] Hand hygiene is crucial for children's healthy growth, effectively reducing the risk of bacterial and viral infections. However, children are often too short for traditional, fixed-height sinks to use independently—they either can't reach the faucet or can't fully insert their hands into the basin. This not only affects the cleaning effect but may also require adult assistance, making it inconvenient and reducing children's motivation to wash their hands voluntarily.

[0003] To address this issue, there is an existing technology for a height-adjustable handwashing basin (CN105672424A). Its core feature is a lifting device connected to the lower end of the basin. The height is adjusted via a hydraulic cylinder and a lifting switch. Children can operate the switch according to their own height to adjust the basin to a suitable height without the need for adults to hold them. It also has a simple structure and low cost, thus solving the problem of ease of use to a certain extent.

[0004] However, the aforementioned height-adjustable handwashing basins can only adjust the height and cannot assist in cleaning children's hands. When children wash their hands independently, they often fail to achieve the desired hygiene results due to improper cleaning methods or incomplete cleaning. This is especially true for younger children who lack proper handwashing skills. Simply relying on manual rubbing can easily miss areas such as between fingers and palms, still posing a risk of incomplete hand cleaning and failing to fundamentally guarantee children's hand hygiene.

Detailed Implementation

[0025] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples. The embodiments of this utility model are not limited to the following examples, and this utility model relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0026] like Figures 1 to 6 As shown, this utility model provides a technical solution: an ultrasonic hand cleaning device for children's health protection, including a fixed box 1 and a washbasin 2 installed on the top of the fixed box 1. The fixed box 1 is provided with a basin adjustment component 3 connected to the washbasin 2. A vertical plate 7 is installed on the rear side of the fixed box 1. An installation plate 41 is provided on the front surface of the vertical plate 7. A faucet 42 is provided below the center of the installation plate 41. A water outlet adjustment component 4 is provided on the rear side of the vertical plate 7 and connected to the installation plate 41. The washbasin 2 includes an outer basin 22 that can be raised and lowered and installed on the top of the fixed box 1, and an inner basin 21 installed inside the outer basin 22. Cleaning components 5 are symmetrically arranged inside the inner basin 21. An installation cavity 23 is provided between the bottom of the outer basin 22 and the inner basin 21. An ultrasonic generator 24 is provided inside the installation cavity 23. A control panel 6 is provided on the front surface of the vertical plate 7.

[0027] In this invention, in the basin adjustment assembly 3, the lifting motor 36 drives the commutator 35 to operate, and the transmission shaft 34 transmits power to the turbine transmission structure 33, driving the lead screw 32 to rotate inside the outer cylinder 31. This, combined with the sliding guide of the inner wall limiting groove 11 of the fixed box 1 and the slider 25 of the outer basin 22, enables stable lifting and lowering of the outer basin 22, allowing children of different heights to achieve a suitable height. The adjustment motor 43 drives the rotating shaft 44 and the gear 46 to rotate. The gear 46 meshes with the rack 45, and the rack 45 slides along the vertical rod of the limiting sliding frame 47. The connecting plate 411 drives the mounting plate 41 and the faucet 42 to rise and fall along the lifting channel 71, so that the water flow accurately falls on the child's hands, improving the convenience of use. During cleaning, in the cleaning component 5 of the inner basin 21, the drive motor 52 drives the cleaning ball 51 to rotate through the connecting shaft 53, and the cleaning protrusion 54 assists in rubbing the hands; at the same time, the ultrasonic generator 24 in the mounting cavity 23 works, using ultrasonic vibration to deeply clean the gaps between the fingers and other parts. The sewage in the inner basin 21 is discharged through the water outlet pipe 26, thus solving the problem of children's manual cleaning not being thorough and improving the cleaning effect.

[0028] It should be noted that the control panel 6 integrates multiple control buttons, corresponding to functions such as raising and lowering the washbasin 2, raising and lowering the faucet 42, starting the cleaning component 5, operating the ultrasonic generator 24, and draining. It establishes an electrical connection with the drive elements of each component through internal circuitry to achieve centralized control. When a child or guardian presses the corresponding button, the control panel 6 sends an electrical signal to the target component. Pressing the raise / lower button sends a signal to the raise / lower motor 36, controlling its forward and reverse rotation, which drives the outer basin 22 to rise and fall via the basin adjustment component 3; pressing the faucet adjustment button sends a signal to the adjustment motor 43, driving the water outlet adjustment component 4 to raise and lower the faucet 42 synchronously; pressing the cleaning button triggers the drive motor 52 to rotate, driving the cleaning ball 51 to rotate, and simultaneously starting the ultrasonic generator 24; pressing the drain button controls the electronic valve of the water outlet pipe 26 to open and drain water.

[0029] As one of the preferred embodiments of this utility model, such as Figure 1 As shown, the inner wall of the fixed box 1 is provided with a limiting groove 11, and the outer wall of the outer basin 22 is provided with a slider 25 that can slide in cooperation with the limiting groove 11.

[0030] The limiting groove 11 is a groove that extends vertically along the inner wall of the fixed box 1. Its length covers the maximum lifting range of the outer basin 22. The slider 25 is a protrusion on the outer wall of the outer basin 22. Its size matches the limiting groove 11 and it can be embedded in the groove. When the basin adjustment component 3 drives the outer basin 22 to lift, the slider 25 slides synchronously along the limiting groove 11, thereby limiting the direction of movement of the outer basin 22 and preventing it from shifting left or right or rotating during lifting, thus ensuring that the outer basin 22 lifts and lowers smoothly.

[0031] As one of the preferred embodiments of this utility model, such as Figure 1As shown, the washbasin 2 is provided with a water outlet pipe 26 that passes through the bottom center of the outer basin 22 and the inner basin 21, and the water outlet pipe 26 is connected to an electronic valve in the mounting cavity 23.

[0032] The drain pipe 26 runs through the center of the bottom of the outer basin 22 and the inner basin 21, and can concentrate and drain the sewage in the inner basin 21. Its material has a certain degree of flexibility. When in use, the drain pipe 26 needs to be connected to the drain pipe through a pipe to facilitate the discharge of sewage in the inner basin 21. It can extend and retract slightly with the raising and lowering of the outer basin 22 to avoid affecting the raising and lowering of the washbasin 2. The electronic valve is connected to the control panel 6 through a circuit. When the drain button of the control panel 6 is pressed, the electronic valve receives a signal and opens, and the sewage in the inner basin 21 is discharged through the drain pipe 26. After cleaning, the automatic shut-off program can also be set through the control panel 6, and the electronic valve will close to prevent odor backflow and ensure hygiene.

[0033] As one of the preferred embodiments of this utility model, such as Figure 1 As shown, the basin adjustment assembly 3 includes an outer cylinder 31 symmetrically erected and installed on the bottom surface of the fixed box 1, a lead screw 32 disposed inside the outer cylinder 31, a turbine transmission structure 33 disposed on one side of the top of the outer cylinder 31, a commutator 35 disposed between the outer cylinders 31, and a lifting motor 36 that is connected to the commutator 35 in a transmission manner. The commutator 35 is provided with a drive shaft 34, and the commutator 35 is connected to the turbine transmission structure 33 in a transmission manner through the drive shaft 34.

[0034] A fixing plate 12 is provided on the inner wall of the fixing box 1, and the lifting motor 36 and the commutator 35 are mounted on the fixing plate 12.

[0035] The power for the basin adjustment assembly 3 is provided by the lifting motor 36, which is mounted on the fixed plate 12 together with the commutator 35. The fixed plate 12 provides stable support for both to prevent shaking during operation. The symmetrically arranged outer cylinder 31 provides mounting support for the lead screw 32. After the lifting motor 36 is started, the power is transmitted to the commutator 35. The commutator 35 distributes the power to the turbine transmission structures 33 on both sides through the transmission shaft 34. The top of the lead screw 32 is connected to the bottom of the outer basin 22. The turbine transmission structure 33 converts the power into the rotational motion of the lead screw 32. When the lead screw 32 rotates in the outer cylinder 31, it drives the outer basin 22 to rise and fall through the threaded transmission.

[0036] As one of the preferred embodiments of this utility model, such as Figure 1 , Figure 3As shown, the water outlet adjustment assembly 4 includes a limiting sliding frame 47 symmetrically arranged on the rear surface of the vertical plate 7, a rack 45 slidably arranged in the limiting sliding frame 47, a gear 46 located on the upper end of the rack 45 and meshing with the rack 45, a rotating shaft 44 fixedly sleeved inside the gear 46, and an adjustment motor 43 installed on the rear surface of the vertical plate 7 and connected to one end of the rotating shaft 44. The limiting sliding frame 47 is provided with a mounting post 471 on the side surface of the vertical plate 7 near the vertical plate 7, and the limiting sliding frame 47 is installed on the rear surface of the vertical plate 7 through the mounting post 471.

[0037] The power for the water outlet regulating assembly 4 is provided by the regulating motor 43, which is mounted on the rear side of the vertical plate 7. It drives the rotating shaft 44 to rotate the gear 46. The gear 46 meshes with the rack 45, converting the rotational motion into the linear motion of the rack 45. The limiting sliding frame 47 is fixed to the rear side of the vertical plate 7 by the mounting column 471, providing a sliding track for the rack 45 and restricting its movement to only the vertical direction to prevent deviation.

[0038] When the control panel 6 sends a signal to the regulating motor 43, the motor rotates in both directions, causing the gear 46 to rotate accordingly. The rack 45 slides up and down along the limiting sliding frame 47, which in turn drives the mounting plate 41 and the faucet 42 to rise and fall synchronously through the connecting plate 411. This structure, through gear and rack meshing transmission and the guidance of the limiting sliding frame 47, ensures that the faucet 42 rises and falls smoothly and is adapted to the height of the washbasin 2.

[0039] As one of the preferred embodiments of this utility model, such as Figure 3 , Figure 6 As shown, the water outlet adjustment component 4 is symmetrically provided with a fixing component 48 for connecting to the rear surface of the vertical plate 7 at the front and rear ends near the gear 46. The rotating shaft 44 is rotatably sleeved inside the fixing component 48. The fixing component 48 includes an outer sleeve 481 connected to the rear surface of the vertical plate 7 and a bearing 482 installed inside the outer sleeve 481. The rotating shaft 44 is fixedly sleeved inside the inner ring of the bearing 482.

[0040] The fixing components 48 are symmetrically distributed at the front and rear ends of the gear 46 and are connected to the rear side of the vertical plate 7 through the outer sleeve 481 to provide support for the rotating shaft 44. The rotating shaft 44 is fixedly sleeved on the inner ring of the bearing 482, and the bearing 482 is installed inside the outer sleeve 481. When the adjusting motor 43 drives the rotating shaft 44 to rotate, the fixing components 48 can limit the radial displacement of the rotating shaft 44, prevent the gear 46 from deviating when meshing with the rack 45, and ensure stable transmission.

[0041] As one of the preferred embodiments of this utility model, such as Figure 1 , Figure 3As shown, a connecting plate 411 is provided on the rear surface of the mounting plate 41. A lifting groove 71 is provided through the vertical plate 7 at the corresponding positions of the connecting plate 411 and the faucet 42. The connecting plate 411 is located in the lifting groove 71 and its two ends are respectively connected to the mounting plate 41 and the lower end of the rack 45. The faucet 42 is connected to the water inlet pipe through the lifting groove 71.

[0042] The limiting sliding frame 47 is provided with symmetrically arranged vertical rods, and the left and right side walls of the rack 45 are respectively provided with sliding grooves 451 that can slide with the vertical rods.

[0043] The connecting plate 411 is a key component connecting the mounting plate 41 and the rack 45. When the rack 45 is raised or lowered, the mounting plate 41 and the faucet 42 move synchronously through the connecting plate 411. The lifting slot 71 of the vertical plate 7 provides space for the raising and lowering of the connecting plate 411 and the faucet 42, while restricting the direction of movement to prevent deviation.

[0044] The vertical rod of the limiting sliding frame 47 and the sliding groove 451 of the rack 45 form a guiding engagement. When the rack 45 is raised or lowered, the sliding groove 451 slides along the vertical rod to further prevent the rack 45 from wobbling left and right. The faucet 42 is connected to the water inlet pipe through the lifting channel 71 to ensure that the water supply is not affected when it is raised or lowered.

[0045] As one of the preferred embodiments of this utility model, such as Figure 1 , Figure 2 As shown, the cleaning component 5 includes cleaning balls 51 symmetrically arranged inside the inner basin 21, a drive motor 52 arranged in the mounting cavity 23, and a connecting shaft 53 that passes through the bottom of the inner basin 21 and is connected at both ends to the lower ends of the drive motor 52 and the cleaning balls 51, respectively. The surface of the cleaning balls 51 is provided with a plurality of evenly distributed cleaning protrusions 54.

[0046] The cleaning component 5 is powered by a drive motor 52 within the mounting cavity 23, which is connected to the cleaning balls 51 within the inner basin 21 via a connecting shaft 53. When the control panel 6 sends a start signal, the drive motor 52 operates, driving the cleaning balls 51 to rotate via the connecting shaft 53. The cleaning balls 51 are symmetrically distributed within the inner basin 21, allowing for hand cleaning from both sides. The cleaning protrusions 54 on their surface enhance the auxiliary scrubbing effect. The portion of the connecting shaft 53 that penetrates the bottom of the inner basin 21 is sealed to prevent water from entering the mounting cavity 23. The rotation direction and speed of the cleaning balls 51 can be adjusted via the control panel 6. Combined with the vibration of the ultrasonic generator 24, this creates a synergistic effect of mechanical scrubbing and ultrasonic cleaning, addressing the issue of incomplete manual cleaning by children.

[0047] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
