Description

Technical Field

[0001] This utility model relates to the field of sanitary ware technology, and more specifically to an intelligent toilet gas-liquid mixing flushing device and its water system. Background Technology

[0002] The cleaning function of a smart toilet is its core function. The cleaning water is divided into self-aspirated cleaning water and external air pump-mixed cleaning water according to the air mixing method. With the addition of the air pump, the air mixing ratio in the cleaning water increases, making the cleaning more comfortable while ensuring the power.

[0003] Currently, among similar products, the method of changing from airless cleaning to air pump mixed cleaning involves replacing the reversing valve upstream of the cleaning outlet in the water circuit. The reversing valve structure is changed from "one water inlet and multiple water outlets" to "one water inlet, one air inlet and multiple air-liquid mixed outlets", and an air pump is connected to the air inlet of the reversing valve.

[0004] However, by adjusting the structure of the directional valve and adding an air inlet, it is equivalent to adding a new directional valve in the actual manufacturing process, which is not conducive to the uniformity of production materials. Moreover, the directional valve is a component with high precision requirements, and each new directional valve requires a long time to verify, which increases the product development cycle and development cost.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0027] 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 based on the specific circumstances.

[0028] A smart toilet gas-liquid mixing flushing device, such as Figures 1 to 3As shown, the device includes a three-way body, which includes a first housing 1 and a second housing 2. After the first housing 1 and the second housing 2 are connected, an internal cavity is formed inside. The device also includes a water inlet 6, an air inlet 7, and a water outlet 8 that are connected to the internal cavity. A filter element 9 and a one-way valve 10 are provided inside the internal cavity. The filter element 9 is located between the water inlet 6 and the water outlet 8, and the one-way valve 10 is located between the air inlet 7 and the water outlet 8. The water outlet 8 is connected to a flushing assembly.

[0029] Water enters the three-way body through inlet 6, and air enters the three-way body through inlet 7. After the water and gas are mixed in the mixing chamber 5, they flow out through outlet 8. Outlet 8 is connected to the flushing assembly 17 to directly discharge water. Alternatively, if multiple outlets are required, the reversing valve is connected to outlet 8 without changing the structure of the reversing valve. This achieves the effect of air-mixing cleaning, improves the versatility of the reversing valve in the cleaning water circuit, and simplifies the structure and reduces production and development costs.

[0030] The internal cavity includes a first cavity 3 and a second cavity 4 located in the first housing 1, and a mixing cavity 5 located in either the first housing 1 or the second housing 2. Both the first cavity 3 and the second cavity 4 are connected to the mixing cavity 5. The first housing 1 is provided with a water inlet 6 communicating with the first cavity 3 and an air inlet 7 communicating with the second cavity 4. The first housing 1 or the second housing 2 is provided with a water outlet 8 communicating with the mixing cavity 5. In this embodiment, the water outlet 8 is located on the second housing 2.

[0031] The filter element 9 is disposed within the first receiving cavity 3, and is located between the inlet 6 and the mixing cavity 5. After the water flows into the first receiving cavity 3 through the inlet 6, it needs to be filtered by the filter element 9 before entering the mixing cavity 5. The filter element 9 can be a filter screen or a filter cartridge. In this embodiment, the filter element 9 is a filter screen. The filter screen is placed in the first receiving cavity 3, with its top contacting the first housing 1 and its bottom contacting the second housing 2, thus achieving a stable installation.

[0032] A one-way valve 10 is located in the second receiving cavity 4, between the air inlet 7 and the mixing cavity 5. A support sleeve 11 is provided in the second receiving cavity 4 below the one-way valve 10. The top of the one-way valve 10 contacts the first housing 1, and the bottom of the one-way valve 10 is in clearance fit with the inner wall of the bottom of the support sleeve 11. The outer wall of the bottom of the support sleeve 11 contacts the second housing 2. A through hole 12 is provided at the bottom of the support sleeve 11. The one-way valve 10 communicates with the mixing cavity 5 through the through hole 12, and then with the water outlet 8. Specifically, the one-way valve 10 is provided with an annular boss. The upper surface of the boss mates with the top surface of the second cavity 4, and the lower surface of the boss mates with the top surface of the support sleeve 11. The bottom surface of the support sleeve 11 rests on the second housing 2. When the first housing 1 and the second housing 2 are locked together, the support sleeve 11 compresses and seals the sealing part of the one-way valve 10, so that the gas entering from the inlet 7 can only flow through the one-way valve 10 into the through hole 12 below the support sleeve 11 and enter the mixing chamber 5. This improves the sealing performance of the gas flow channel and further increases the gas flow rate through the small hole.

[0033] In this embodiment, the support sleeve 11 is independently formed and installed inside the inner cavity.

[0034] In other embodiments, the support sleeve 11 may be integrally formed into the body of the tee, specifically formed on the side away from the air inlet 7.

[0035] In this embodiment, the one-way valve 10 is specifically a duckbill type one-way valve 10, with the duckbill part of the one-way valve 10 facing the through hole 12.

[0036] A first housing 1 is fitted onto a second housing 2, and a sealing ring 13 is provided between the first housing 1 and the second housing 2. An annular groove is formed on either the first housing 1 or the second housing 2, and the sealing ring 13 is embedded within the annular groove. Specifically, in this embodiment, an annular groove is formed on the second housing 2, encircling the second housing 2, and the sealing ring 13 is embedded within the annular groove. The outer side of the sealing ring 13 protrudes beyond the annular groove, and the sealing performance between the first housing 1 and the second housing 2 is further improved by the compression of the sealing ring 13.

[0037] The first housing 1 and the second housing 2 are fixedly connected by any one or more combinations of welding, fasteners, and snap-fit ​​connections. In this embodiment, the first housing 1 and the second housing 2 are fixed by fasteners, and the first housing 1 and the second housing 2 are provided with a plurality of lugs and threaded grooves, and bolts are threaded through the lugs and threaded grooves.

[0038] The water inlet 6 is connected to the water supply source; the air inlet 7 is connected to the air supply source, which is the air pump 15; and the water outlet 8 is connected to the reversing valve assembly 16. The water supply source and the air supply source respectively input water flow and air flow into the three-way body, and after mixing in the mixing chamber 5, they enter the reversing valve assembly 16 through the water outlet 8.

[0039] like Figure 4 As shown, this embodiment also proposes an intelligent toilet cleaning water system, including the above-mentioned gas-liquid mixing flushing device, as well as an inlet switch valve 14, a flow meter 19, a water heating component 18, a reversing valve component 16, and a flushing component 17. The gas-liquid mixing flushing device is located at the rear end of the water heating component 18 and is connected to the flushing component 17 through the reversing valve component 16. The flushing component 17 is located inside the intelligent toilet for human body cleaning.

[0040] The working process of this utility model is as follows:

[0041] The water for cleaning the smart toilet is supplied by the inlet valve 14, passes through the flow meter 19 and then enters the water heating component 18. The hot water output enters the three-way body through the inlet 6. A filter screen with a large capacity is provided at the inlet position, which can block most of the dirt flowing out of the front water path and prevent the smaller cleaning outlet at the rear from becoming clogged.

[0042] The gas generated by the air pump 15 enters the three-way body through the air inlet 7, then enters the mixing chamber 5 through the one-way valve 10 and the through hole 12 of the support sleeve 11 to mix with the cleaning water. Finally, the cleaning water containing a large amount of gas flows out from the outlet 8 and enters the reversing valve assembly 16. The reversing valve assembly 16 adjusts the flow rate according to the user control, and finally sprays out through the water outlet of the flushing assembly 17.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
