Description

Technical Field

[0001] The utility model relates to the technical field of nursing beds, and particularly relates to a toilet seat of a nursing bed with a heating function. Background Art

[0002] Nursing beds are specially designed for patients or the elderly with inconvenient mobility to use when receiving home care. The use of nursing beds has long been very common, especially the use of nursing beds for the elderly is increasing, and the usage requirements are also getting higher and higher. Nowadays, most of the nursing beds used by the elderly are equipped with toilet seats, which are convenient for the elderly with inconvenient mobility to use the toilet in bed. However, the currently commonly used nursing beds have some imperfections. Referring to Chinese patent documents CN213283924U and CN212866200U, the prominent defects are as follows:

[0003] First, in cold seasons, especially in cold winters, the temperature of the sitting surface of the toilet seat on the nursing bed is very low, which stimulates the physiological and psychological feelings of the user's buttocks when contacting the sitting surface of the toilet seat, making them uncomfortable or affecting the toilet use process of the user; the sitting surface of the toilet seat is not antibacterial and is prone to breeding mold and viruses, which is not conducive to the long-term use of the nursing bed by the user.

[0004] Second, the structural design of the toilet seat of the currently commonly used nursing bed with a heating function has deficiencies. The upper wall edge of the inner wall of the toilet bowl is easily adhered to by splashed feces and urine, and the flushing water flow of the toilet seat does not pass through the upper wall edge of the toilet seat, resulting in feces and urine remaining after the use of the toilet seat and overflowing with a foul smell; the water flow for flushing the inner wall of the toilet seat and flushing into the feces collection pit is a vertical linear water flow, and the feces and urine cannot be flushed clean, leaving feces and urine residues, and it is necessary to manually wipe the upper wall edge of the inner wall of the toilet bowl and the feces and urine residues in the toilet bowl to maintain the cleanliness of the toilet seat of the nursing bed with a heating function.

[0005] Third, a urine baffle is installed above the front end of the toilet seat of some nursing beds with a heating function. The urine baffle can prevent urine from splashing, but it is difficult to be flushed with water inside the urine baffle, and the flushing water flow of the toilet seat does not pass through the urine baffle, resulting in feces and urine remaining after the use of the urine baffle and overflowing with a foul smell. Content of the Utility Model

[0006] The technical problem to be solved by the utility model is to provide a toilet seat of a nursing bed with a heating function in view of the above-mentioned deficiencies of the prior art, which can solve one or more of the above technical defects.

[0007] The technical solution of the first aspect of the present utility model is: a toilet seat for a nursing bed with a heating function, including a toilet seat main body. An upwardly extending wall ring is connected to the outer edge of the upper end of the toilet seat main body. A toilet seat ring is installed at the upper end of the wall ring. A wall groove is formed in a circular shape between the top side of the toilet seat main body, the inner side of the wall ring, and the lower side of the toilet seat ring. A water spray nozzle is installed at the rear end of the wall ring. The water spray direction of the water spray nozzle faces into the wall groove. The rear end of the water spray nozzle is connected to a main water delivery pipe.

[0008] The toilet seat for a nursing bed with a heating function of the present utility model changes from the existing flushing method of a closed pipeline with hole distribution to a wall groove flushing method. In the existing closed pipeline flushing structure, the outer wall of the pipeline is easily adhered to by the ejected feces and stains, and the water flow cannot reach for flushing, resulting in the overflow of foul odors from the feces and stains. Since the closed pipeline flushing method is a hole distribution type, the water jets ejected from the closed pipeline are almost vertical water lines, and there will be parts that cannot be flushed between the water lines. Moreover, the water flow formed after the convergence of the water lines cannot form a swirling water flow for flushing the inner wall of the toilet seat, and the impact force of the water flow on the feces and stains entering the feces collection pit is insufficient, making it easy to leave feces and stains remaining on the inner wall or bottom of the toilet seat. The wall groove flushing structure has the flushing water flow exposed, and all parts sprayed with feces and stains can be flushed by the flushing water flow. The water flow ejected from the water spray nozzle can spray into the wall groove, and the water flow direction is guided by the wall groove. The converging water for flushing the inner wall of the toilet seat and impacting the feces and stains into the feces collection pit will form a swirling water flow with a strong flushing force. After the toilet seat is flushed by the swirling water flow, there will be no trace of feces and stains left at any part, solving the drawbacks existing in the commonly used toilet seats for nursing beds with a heating function, enhancing the cleaning, hygiene, and comfort experience during the use of the nursing bed; maintaining the cleaning and hygiene during and after the use of the toilet seat for a nursing bed with a heating function, and improving the quality of life in terms of health and hygiene. The present utility model has a heating function, solving the problem of cold stimulation to the buttocks skin when the elderly use the toilet on the nursing bed, especially in cold seasons, especially in winter, and maintaining the normal psychological and physiological feelings during toilet use; the heating sheet of the toilet seat ring will not fall off, is safe and durable, and the effect of warming the user's buttocks is prominent. In addition, the toilet seat ring contains silver oxide nano materials with antibacterial and antiviral properties and is made of polydimethylsiloxane (food grade) materials with high tensile strength, high temperature resistance (used in the range of -60°C to +200°C), chemical corrosion resistance, waterproofness, and moisture resistance.

[0009] There are two installation methods for the water spray nozzle. The first installation method is to install the water spray nozzle at the upper right rear end of the wall ring. The water spray direction of the water spray nozzle faces inside the left end of the wall groove. The water sprayed by the water spray nozzle can spray inside the left end of the wall groove. Part of the water then flows along the wall groove to inside the right end of the wall groove, and then all the water in the wall groove rushes into the toilet bowl main body together to form a swirling water flow. The second installation method is to install the water spray nozzle at the upper left rear end of the wall ring. The water spray direction of the water spray nozzle faces inside the right end of the wall groove. The water sprayed by the water spray nozzle can spray inside the right end of the wall groove. Part of the water then flows along the wall groove to inside the left end of the wall groove, and then all the water in the wall groove rushes into the toilet bowl main body together to form a swirling water flow. The installation position and water spray direction of the water spray nozzle of the present utility model can achieve oblique water spraying, so that the sprayed water can quickly flow along the wall groove inside the wall groove, enabling the wall groove to play a good guiding role and better forming a swirling water flow with a strong flushing force.
