Description

Technical Field

[0001] The invention relates to the technical field of nursing beds, and in particular to a nursing bed toilet. Background Art

[0002] Nursing beds are beds designed for patients with limited mobility or the elderly who are cared for at home. Nursing beds have long been widely used, especially for the elderly, and the requirements for use are getting higher and higher. Most of the nursing beds used by the elderly today are equipped with toilets to facilitate the elderly with limited mobility to use the toilet in bed. However, the nursing beds commonly used today have imperfections. Referring to Chinese patent documents CN213283924U and CN212866200U, the prominent defects are as follows: 1. In cold weather, especially in winter, the temperature of the seat surface of the nursing bed is very low, which causes physiological and psychological stimulation when the user's buttocks skin touches the seat surface, causing discomfort or affecting the user's toileting process; the toilet seat surface is not antibacterial and is prone to breed mold and viruses, which is not conducive to the user's long-term use of the nursing bed.

[0003] 2. The structural design of the toilet bowl in common use today for nursing beds has shortcomings. The upper wall edge of the inner wall of the toilet bowl is easily stained by sprayed feces, and the flushing water flow of the toilet bowl does not pass through the upper wall edge of the toilet bowl, resulting in feces remaining after the toilet bowl is used and overflowing with a fecal odor; the water flow for flushing the inner wall of the toilet bowl and flushing into the feces collection pit is a vertical linear water flow, and the feces are not flushed cleanly, and there is feces left. It is necessary to manually wipe off the upper wall edge of the inner wall of the toilet bowl and the feces left in the bowl to maintain the cleanliness of the nursing bed toilet.

[0004] 3. Some nursing beds have a urinal installed on the front end of the toilet bowl. The urinal can prevent urine from splashing, but the urinal is difficult to flush with water, and the flushing water of the toilet bowl does not pass through the urinal, resulting in fecal stains left in the urinal after use, and overflowing with fecal odor. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a nursing bed toilet in view of the deficiencies of the above-mentioned prior art, which can solve one or more of the above-mentioned technical defects.

[0006] The technical solution of the first aspect of the present invention is: a nursing bed toilet, including a toilet body, a wall ring extending upward is connected to the outer edge of the upper end of the toilet body, a seat ring is installed on the upper end of the wall ring, and the top side of the toilet body, the inner side of the wall ring and the lower side of the seat ring form a wall groove; a water spray port is installed at the rear end of the wall ring, the water spray direction of the water spray port is toward the wall groove, and the rear end of the water spray port is connected to the main water supply pipe.

[0007] The nursing bed toilet of the present invention is changed from the closed pipe plus hole distribution flushing method in the prior art to the wall groove flushing method. The closed pipe flushing structure in the prior art causes the outer wall of the pipe to be easily stuck by the ejected feces and dirt, which cannot be flushed by the water flow, and the feces and dirt overflow and smell bad; because the closed pipe flushing method is a hole distribution, the water line flow ejected from the closed pipe is almost vertical, there will be parts that cannot be flushed between the water line flows, and the water flow beam formed after the water line flows merge cannot form a vortex water flow to rinse the inner wall of the toilet bowl, and the force of the water flow beam to impact the feces and dirt into the feces collection pit is not enough, and the feces and dirt are easily left on the inner wall or bottom of the toilet bowl. The wall groove flushing structure has the flushing water flow exposed, and all parts sprayed with feces and sewage can be flushed by the flushing water flow. The water flow sprayed from the water nozzle can be sprayed into the wall groove, and the direction of the water flow is guided by the wall groove. The collected water that flushes the inner wall of the toilet bowl and impacts the feces and sewage into the collecting pit will form a vortex water flow with strong flushing force. After the toilet bowl is flushed by the vortex water flow, no feces and sewage will be left in any part, which solves the shortcomings of the nursing bed toilet bowl commonly used today, and improves the cleanliness, hygiene and comfort experience of the nursing bed; it maintains the cleanliness and hygiene of the nursing bed toilet bowl during and after use, and improves the quality of hygienic and healthy life.
