Description

Technical Field

[0001] The utility model relates to the technical field of medical waste treatment, in particular to a spray mechanism for a bedpan grinder. Background Art

[0002] Hospital waste refers to all waste that needs to be discarded and cannot be reused in hospitals, including biological and non-biological waste, as well as domestic waste. Medical waste refers to waste generated during the diagnosis, treatment, and nursing of patients.

[0003] Medical waste may contain a large number of pathogenic microorganisms and harmful chemicals, and even radioactive and damaging substances. Therefore, medical waste is an important risk factor causing disease transmission or related public health problems.

[0004] During hospitalization, many patients need assistance from caregivers due to mobility problems and other reasons. Disposable paper bedpans and chamber pots are commonly used assistive devices for patients, and these assistive devices are usually discarded directly after use.

[0005] The traditional treatment process is that hospitals can only collect these used disposable paper bedpans together with other medical waste and transport them to special medical waste treatment sites for incineration and other harmless treatment;

[0006] However, because these disposable paper bedpans are usually accompanied by excrement and are likely to carry a large number of pathogens, patients directly discarding them is not only prone to leakage, but also very easy to pollute the environment; and because disposable paper bedpans are relatively hard in texture (requiring sufficient strength) and are not small in size, they are not conducive to storage. Direct disposal of them can easily take up a lot of space, resulting in low utilization of storage facilities such as trash cans.

[0007] In the traditional treatment process, medical waste is usually pre-treated with a crushing device, but these existing crushing devices do not have a cleaning function, resulting in various dirt attached to the inside after long-term use. This dirt will not only corrode internal components, but also affect subsequent use and even breed bacteria.

[0008] In summary, there is currently no special treatment device for disposable paper bedpans on the market, which has the problems of inconvenient disposal and lack of cleaning function. Utility Model Content

[0009] The purpose of the utility model is to provide a spray mechanism for a bedpan crusher. The utility model has the advantages of being easy to handle and being able to effectively clean the inside of the device.

[0010] The technical solution of the utility model: a spray mechanism for a bedpan crusher comprises a machine body, a top frame arranged on the top of the machine body, a water storage tank arranged on the back of the machine body, a crushing cylinder detachably arranged in the machine body and corresponding to the top frame, a sealing cover rotatably opened and closed and arranged on the upper middle part of the top frame, a crushing unit arranged in the crushing cylinder, a cylinder mounting unit arranged in the machine body for mounting the crushing cylinder, and a spray system arranged in the machine body and respectively connected to the water storage tank, the sealing cover and the crushing cylinder; the spray system comprises a water pump arranged in the machine body, an air intake assembly arranged on the outer side of the upper part of the crushing cylinder, a sewage pipe arranged on one side of the bottom of the crushing cylinder, a spray head arranged in the middle of the inner side of the sealing cover, and a plurality of water pipes arranged in the machine body.

[0011] In the aforementioned spray mechanism for the toilet bowl crusher, a water inlet joint is provided on the inner side of the bottom of the water storage tank, and a pair of water inlet and outlet interfaces are provided on the water pump. The water inlet joint is connected to the water inlet and outlet interfaces through a water pipe, and the water inlet and outlet interfaces are respectively connected to the spray head and the air intake assembly through the water pipe and the water diversion joint.

[0012] In the aforementioned spray mechanism for the toilet bowl grinder, a U-shaped structure is provided at the bottom of the sewage pipe, and the end is connected to the outside through a sewage outlet; a side water inlet interface is provided on one side of the sewage pipe, and the side water inlet interface is connected to the bottom of the air intake assembly through a water pipeline.

[0013] In the aforementioned spray mechanism for the bedpan crusher, a rotating spray head is provided at the bottom of the spray head, and the inner side of the bottom of the sealing cover is concave; a secondary water inlet is opened on one side of the bottom of the crushing cylinder, and the secondary water inlet is connected to the inlet and outlet water interfaces through a water pipeline and a water diversion joint; the upper end of the air intake assembly is connected to the breathing valve through an air pipe; and a pressure sensor is connected to the bottom of the crushing cylinder.

[0014] In the aforementioned spray mechanism for the bedpan crusher, a detachable front cover is provided on the front side of the body, and a pedal groove is provided in the middle of the front side of the bottom of the body; an infrared sensing unit is provided in the pedal groove, and the infrared sensing unit is connected to the sealing cover through a control system.
