Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of nursing handwashing station bodies, specifically a nursing handwashing station with splash-proof function. Background Technology
[0002] In healthcare settings, handwashing is a crucial step in preventing and controlling the spread of pathogens and protecting the health of healthcare workers and patients. Nursing staff perform numerous handwashing procedures daily, but traditional handwashing stations are often poorly designed to address the specific needs of nursing work, resulting in frequent splashing and other problems during actual use.
[0003] First, when water flows directly onto the surface of a conventional handwashing sink, it causes water to splash everywhere. This not only keeps the area around the sink constantly wet, increasing the risk of slipping and falling, but also poses a particularly significant potential danger to patients with mobility issues or busy medical staff.
[0004] Secondly, splashed water can easily carry pathogens such as bacteria and viruses, contaminating the environment around the sink, such as walls, countertops, and stored medical tools. These contaminated areas become new sources of pathogen transmission, greatly increasing the chance of cross-infection and seriously threatening the hygiene and safety of the medical environment. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a splash-proof handwashing station, solving the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a splash-proof handwashing station, comprising a handwashing station body, a washbasin, and mounting holes;
[0007] The washbasin is installed inside the main body of the washbasin, and the mounting hole is opened on the main body of the washbasin for installing a faucet;
[0008] A splash guard is provided inside the washbasin. The splash guard is shaped to match the outline of the washbasin opening, has a ring structure, and has perforated holes.
[0009] Furthermore, the perforations on the splash guard are evenly distributed.
[0010] Furthermore, both the splash guard and the washbasin are semi-circular in shape, and the outer diameter of the splash guard is smaller than the inner diameter of the washbasin.
[0011] Furthermore, a limiting ring is provided on the outside of the splash guard, which fits against the upper surface of the washbasin body.
[0012] Furthermore, a one-centimeter gap is maintained between the outer side of the splash guard and the inner wall of the washbasin.
[0013] Furthermore, the upper surface of the washbasin is integrally formed with a closing part.
[0014] Furthermore, the inner diameter of the opening at the upper end of the closing part is smaller than the inner diameter of the opening at the upper end of the splash guard.
[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0016] This splash-proof handwashing station effectively reduces water splashing onto the area around the station body during handwashing through the combined effect of splash-proof panels, perforations, gaps, and closures. This keeps the area around the station dry, significantly reducing the risk of slips and falls for patients with mobility issues or busy medical staff. It also reduces water stains and rust caused by prolonged exposure to splashing water, prevents the cabinet from warping due to moisture, extends the lifespan of the station body and surrounding facilities, and lowers maintenance and replacement costs.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-3 This embodiment of a splash-proof handwashing station includes a handwashing station body 1, a hand basin 2, and mounting holes 3;
[0023] The washbasin 2 is installed inside the washbasin body 1, and the mounting hole 3 is opened on the washbasin body 1 for installing a faucet;
[0024] A splash guard 4 is installed inside the washbasin 2. The shape of the splash guard 4 is adapted to the outline of the opening of the washbasin 2. It has a ring structure and has hollow holes 5.
[0025] In actual installation, the perforated holes 5 on the splash guard 4 are evenly distributed. Both the splash guard 4 and the washbasin 2 are semi-circular in shape, and the outer diameter of the splash guard 4 is smaller than the inner diameter of the washbasin 2. A limiting ring 6 is provided on the outer side of the splash guard 4 to fit against the upper surface of the washbasin body 1.
[0026] In actual installation, the shape and size design of the splash guard 4 and the washbasin 2 allow the splash guard 4 to be stably placed inside the washbasin 2, effectively utilizing the space of the washbasin 2, while also facilitating installation and disassembly, and making cleaning and maintenance convenient.
[0027] In addition, a one-centimeter gap is maintained between the outer side of the splash guard 4 and the inner wall of the washbasin 2.
[0028] In actual installation, the gap between the splash guard 4 and the washbasin 2 can ensure that the water flow can pass through smoothly, and can also buffer the impact of the water flow to a certain extent.
[0029] In actual use, the faucet is first installed on the mounting hole 3 of the main body 1 of the washbasin, and then the splash guard 4 is placed into the wash basin 2 so that the limiting ring 6 fits against the upper surface of the main body 1 of the washbasin. When the caregiver turns on the faucet to wash their hands, the water flow will first impact the splash guard 4. Since the perforated holes 5 are evenly distributed, the water flow will be dispersed into the wash basin 2 through the perforated holes 5, instead of directly impacting the bottom of the wash basin 2 and causing splashing water.
[0030] Meanwhile, the gap between the splash guard 4 and the inner wall of the washbasin 2 allows some water to flow slowly down along the gap, further buffering the water flow speed. In addition, the upper end of the washbasin 2 is integrally formed with a closing part 7. The inner diameter of the upper opening of the closing part 7 is smaller than the inner diameter of the upper opening of the splash guard 4. The closing part 7 of the washbasin 2 can effectively block the water splashed from the edge of the splash guard 4, so that it will not splash onto the surrounding area of the washbasin body 1.
[0031] The working principle of the above embodiments is as follows:
[0032] When the caregiver turns on the faucet, the water flows out and impacts the splash guard 4. Because the splash guard 4 is annular and has evenly distributed perforated holes 5, the water flow is dispersed through the perforated holes 5, avoiding concentrated impact on the bottom of the washbasin 2 and causing water to splash everywhere. The dispersed water flow flows through the perforated holes 5 into the gap between the splash guard 4 and the inner wall of the washbasin 2. The existence of the gap slows down the water flow speed and further reduces the possibility of splashing. At the same time, the limiting ring 6 on the outer side of the splash guard 4 ensures that the splash guard 4 is fixed in position, so that it can continuously and stably play the role of splash prevention. The closing part 7 on the upper end of the washbasin 2, because its upper opening inner diameter is smaller than the upper opening inner diameter of the splash guard 4, can effectively block the water splashes from the edge of the splash guard 4, confining the water splashes inside the washbasin 2, thereby realizing the splash prevention function of the entire nursing handwashing unit 1 and reducing the impact of water splashes on the surrounding environment during handwashing.
