Description

Technical Field

[0001] This utility model relates to a toilet bowl cleaning machine, and more particularly to a sealing structure for a toilet bowl cleaning machine. Background Technology

[0002] Some bedridden patients who are unable to care for themselves often need to use bedpans in their daily lives. The excrement in bedpans contains a large number of pathogens, so extra care is needed when cleaning them. The common method for cleaning bedpans is to place the bedpan to be cleaned into a medical bedpan cleaning machine, using a rinsing spray to remove dirt adhering to the cleaning items or the inner walls of the cleaning chamber using the force of the water. Moist heat disinfection is then used to kill intestinal pathogens, pyogenic cocci, common hospital-acquired infection bacteria, and pathogenic fungi in the bedpan.

[0003] Existing toilet cleaning machines generate aerosols containing viruses and bacteria during the cleaning process. If the machine is not properly sealed, these aerosols can easily escape, causing the spread of viruses and bacteria and contaminating the external environment, increasing the risk of infection for cleaning personnel. Therefore, toilet cleaning machines need to ensure high sealing performance. However, existing toilet cleaning machines typically only have a single sealing strip at the lid, which is not ideal and needs improvement.

[0004] In addition, the current machine cover with sealing strips cannot guarantee the flatness of the sealing door. Therefore, unevenness of the sealing surface is easily caused during the sealing process. In some places, the sealing strip is squeezed very tightly, while in other places the sealing strip may not be fully adhered, resulting in a decrease in sealing performance. Utility Model Content

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0020] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] Example:

[0022] like Figs. 1-2 As shown, the sealing structure of the toilet bowl cleaning machine includes a body 1, a cleaning tank 11 inside the body 1, a cover 2 above the opening of the cleaning tank 11, a first sealing ring 3 at the opening of the cleaning tank 11, the first sealing ring 3 including a support part 31, a first groove 32 on the outer side of the support part 31, a second groove 33 on the inner side of the support part 31, a slot 34 between the first groove 32 and the second groove 33, the depth of the slot 34 being greater than the depth of the first groove 32 and the second groove 33; the inner side of the cover 2 has an annular groove 21, a compression elastic element 22 inside the annular groove 21, a second sealing ring 23 corresponding to the slot 34 on the compression elastic element 22, a first limiting edge 24 corresponding to the first groove 32 on the outer side of the annular groove 21 on the cover 2, and a second limiting edge 25 corresponding to the second groove 33 on the inner side of the annular groove 21 on the cover 2.

[0023] When the cover 2 closes over the opening of the cleaning tank 11, the first limiting edge 24 inserts into the first groove 32, and the second limiting edge 25 inserts into the second groove 33, positioning the second sealing ring 23 so that it is accurately inserted into the slot 34, forming a multiple seal. Furthermore, under the action of the compression elastic element 22, the second sealing ring 23 presses against the first sealing ring 3, tightly fitting together to reduce gaps and improve sealing. The support part 31 also acts as a buffer when the cover 2 closes, protecting the cover 2 and the cleaning tank 11 from excessive impact that could damage the cover 2 or the cleaning tank 11.

[0024] A gap 26 is formed between the second sealing ring 23 and the two side walls of the annular groove 21. The top of the support part 31 extends upward on both sides of the slot 34 to form a protrusion 35 that extends into the gap 26 of the annular groove 21. When the cover 2 closes the cleaning tank 11, the protrusion 35 on the first sealing ring 3 is inserted into the gap 26 of the annular groove 21, which can improve the sealing performance, connection strength and stability between the cover 2 and the body 1.

[0025] The support portion 31 has a first hollow portion 36 inside, the shape of which matches the shape of the support portion 31. The second sealing ring 23 has a second hollow portion 27 inside, the shape of which matches the shape of the second sealing ring 23. During the cleaning process, the cleaning tank 11 of the toilet bowl cleaning machine is in a high-heat state, which heats the gas in the first hollow portion 36 and the second hollow portion 27, causing it to expand. This makes the first sealing ring 3 and the second sealing ring 23 fit more snugly against each other, as well as against the cleaning tank 11 and the machine cover 2, strengthening the sealing and improving the sealing effect.

[0026] The slot 34 has a trapezoidal cross-section that is wider at the top and narrower at the bottom, and the second sealing ring 23 matches the slot 34. When the second sealing ring 23 is inserted into the slot 34, it compresses the first sealing ring 3. The trapezoidal design causes the contact area between the second sealing ring 23 and the first sealing ring 3 to gradually decrease from top to bottom, thereby increasing the contact pressure and improving the sealing performance.

[0027] The inner wall of the cleaning tank 11 is provided with a slot, and the outer wall of the first sealing ring 3 is provided with a retaining ring 37 corresponding to the slot. The first sealing ring 3 is detachably connected to the cleaning tank 11 through the cooperation of the retaining ring 37 and the slot, which facilitates replacement.

[0028] The annular groove 21 is also equipped with an adsorption strip 28, which is filled with an adsorbent, such as activated carbon. The compression elastic element 22 is located between the adsorption strip 28 and the second sealing ring 23. The adsorption strip 28 can adsorb odors in the cleaning tank 11. If aerosols or vapors escape from the first sealing ring 3 and the second sealing ring 23, they can also be adsorbed by the adsorption strip 28, providing further protection.

[0029] The parts of this utility model not described in detail are existing technologies and therefore will not be specifically described here.
