Description

Technical Field

[0001] This utility model relates to the field of bathroom fixtures, and in particular to a detergent slow-release device and a urinal. Background Technology

[0002] Traditional urinals are flushed directly with municipal tap water, which easily leaves residue and bacteria. Over time, the wash surface becomes filthy and smelly. To address this, some detergent dispensing devices have been developed for urinals to clean and disinfect them. However, some devices simply place solid detergent in a dissolving chamber. During flushing, water enters the chamber to dissolve the detergent, and the resulting liquid is carried away to clean the urinal. This method leads to significant detergent waste. Other devices have a detergent reservoir and a water reservoir connected by a moving part. When flushing, this part opens, mixing the water in the reservoir with the detergent in the reservoir to clean the urinal. While this method reduces detergent usage, it is more complex, more expensive, and prone to malfunction. Utility Model Content

[0003] This utility model addresses the technical problems existing in the prior art by providing a detergent slow-release device and a urinal. Through structural improvements, it can reduce the amount of detergent used and make the overall structure simpler.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a detergent slow-release device, including a main cavity and a storage cavity for holding detergent. The main cavity is provided with a first water inlet, a mixing outlet and a liquid inlet. The storage cavity is provided with a second water inlet and a liquid outlet. The liquid outlet of the storage cavity is connected to the liquid inlet of the main cavity. When water enters through the first water inlet and the second water inlet, the liquid in the storage cavity enters the main cavity and mixes with water to form a mixed liquid. The mixed liquid is output through the mixing outlet.

[0005] Furthermore, the main cavity includes an inlet area and a mixing area that are interconnected. The first inlet is connected to the inlet area, and the mixing outlet and the inlet are connected to the mixing area. The inlet area is provided with an outlet that is connected to the second inlet.

[0006] Furthermore, the water inlet area is provided with a main water inlet throttling plate that cooperates with the first water inlet and a water distribution throttling plate that cooperates with the water outlet; the water passage area of ​​the first water inlet is larger than the water passage area of ​​the water outlet, and the first water inlet and the water outlet are arranged opposite to each other.

[0007] Furthermore, the mixing zone is configured as a Venturi tube, which includes a first tube section and a second tube section distributed sequentially along the liquid flow direction. The inner diameter of the first tube section is smaller than the inner diameter of the second tube section, and the liquid inlet is located on the side wall of the second tube section.

[0008] Furthermore, a one-way valve is provided between the liquid outlet and the liquid inlet, which only allows liquid to flow from the liquid outlet to the liquid inlet.

[0009] Furthermore, the second water inlet is located at the top of the storage chamber; the outlet is located below the location of the second water inlet and above the bottom of the storage chamber.

[0010] Furthermore, the cleaning agent is a solid cleaning agent, and the storage chamber is provided with a filter screen that fits at the liquid outlet; or, the cleaning agent is a liquid cleaning agent.

[0011] Furthermore, the main cavity is located in a mixer, and the storage cavity is located in a storage box; the storage box includes a box body with the liquid outlet and a box cover with the second water inlet, the upper end of the box body has an opening, the box cover is sealed to the upper opening of the box body, and the two together form the storage cavity.

[0012] This utility model also provides a urinal, including a urinal body, which is provided with a flushing nozzle, and also includes a detergent slow-release device as described in this utility model above, characterized in that: the mixed liquid outlet is connected to the inlet end of the flushing nozzle.

[0013] Furthermore, the urinal body has a receiving groove on the back side, in which the detergent release device is placed; it also includes a solenoid valve, which controls whether the detergent release device is inlet or not.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The cleaning agent slow-release device of this utility model includes the main body cavity and the storage cavity. When water is introduced, the cleaning agent is automatically and quantitatively released by water power, which can reduce the amount of cleaning agent used. In addition, there is no need to set up additional moving parts, making the overall structure simpler, with lower cost and lower failure rate.

[0016] 2. Since the main cavity includes an interconnected water inlet area and a mixing area, and the water inlet area is provided with a water outlet that is connected to the second water inlet of the storage cavity, this utility model can directly utilize the main cavity to divert water to supply water to the storage cavity, thus eliminating the need for an additional three-way structure.

[0017] 3. The mixing zone is designed as a venturi tube, which ensures that water and liquid from the reservoir are mixed autonomously and uniformly.

[0018] 4. The one-way valve prevents the liquid in the storage chamber from flowing into the water inlet pipe due to negative pressure.

[0041] Please see Figures 1-15 As shown, the present invention provides a detergent slow-release device, including a main cavity and a storage cavity 23 for containing detergent. The main cavity is provided with a first water inlet 11, a mixing outlet 12 and a liquid inlet 13. The storage cavity 23 is provided with a second water inlet 21 and a liquid outlet 22. The liquid outlet 22 of the storage cavity 23 is connected to the liquid inlet 13 of the main cavity. When water enters through the first water inlet 11 and the second water inlet 21, the liquid in the storage cavity 23 enters the main cavity and mixes with the water to form a mixed liquid. The mixed liquid is output through the mixing outlet 12.

[0042] In this embodiment, the main cavity is located in a mixer 1, and the storage cavity 23 is located in a storage box 2. However, this is not a limitation; in other embodiments, the main cavity and the storage cavity 23 are located on the same body. The cleaning agent is specifically a solid cleaning agent 26. The storage cavity 23 is equipped with a filter 27 that fits at the outlet 22 to prevent small particles of the solid cleaning agent 26 that are not completely dissolved from clogging the pipes. In other embodiments, the cleaning agent is a liquid cleaning agent.

[0043] In a preferred embodiment, the main cavity includes an interconnected water inlet zone 15 and a mixing zone 16. A first water inlet 11 connects to the water inlet zone 15, and a mixing outlet 12 and a liquid inlet 13 connect to the mixing zone 16. The water inlet zone 15 is provided with an outlet 14, which connects to a second water inlet 21. The water inlet zone 15 is equipped with a main water inlet throttling vane 111 fitted to the first water inlet 11, and a water distribution throttling vane 112 fitted to the outlet 14. The main water inlet throttling vane 111 controls the total water flow rate, ensuring stable flushing when applied to a urinal. The water distribution throttling vane 112 controls the water intake of the detergent dispenser 2, achieving a quantitative output of detergent. The water passage area of ​​the first water inlet 11 is larger than that of the outlet 14, and the first water inlet 11 and the outlet 14 are positioned opposite each other.

[0044] In this embodiment, the mixing zone 16 is a Venturi tube, which includes a first pipe section and a second pipe section distributed sequentially along the liquid flow direction. The inner diameter of the first pipe section is smaller than that of the second pipe section, and the inlet 13 is located on the side wall of the second pipe section. Thus, when water enters the mixing zone 16, the water flow is accelerated as it passes through the first pipe section, and a negative pressure is generated after the first pipe section. This allows the liquid in the storage chamber 23 to be output through the outlet 22 and smoothly enter the mixing zone 16. Furthermore, the liquid output from the outlet 22 collides with the water flow in the mixing zone 16 to form turbulence, thereby enabling the water to mix autonomously and uniformly with the liquid from the storage chamber 23.

[0045] In this embodiment, a one-way valve 3 is provided between the liquid outlet 22 and the liquid inlet 13. The one-way valve 3 only allows liquid to flow from the liquid outlet 22 to the liquid inlet 13. The second water inlet 21 is located at the top of the storage chamber 23, and the position of the liquid outlet 22 is lower than the position of the second water inlet 21 and higher than the bottom of the storage chamber 23.

[0046] like Figure 2As shown, the mixer 1 includes a mixing body 17, a quick connector 18, a limiting bolt 19, and a movable nut 110. The mixing body 17 has a water inlet area 15, a mixing area 16, a liquid inlet 13, and two openings with mutually perpendicular axes. A main water inlet throttling plate 111 is fitted into one of the openings and is screwed to a quick connector 18. The quick connector 18 forms a first water inlet 11 and is sealed with the mixing body 17 by a first sealing gasket 113. The movable nut 110 is connected to the other opening of the mixing body 17 through the limiting bolt 19. A second sealing gasket 114 is fitted between the limiting bolt 19 and the mixing body 17. A third sealing gasket 114 is fitted inside the movable nut 110, and the movable nut 110 forms a mixing outlet 12.

[0047] like Figure 8 As shown, the storage box 2 includes a box body 24 with a liquid outlet 22 and a box cover 25 with a second water inlet 21. The upper end of the box body 24 has an opening, and the box cover 25 is sealed to the upper opening of the box body 24, and the two together form a storage cavity 23. When solid cleaning agent 26 needs to be added, the box cover 25 can be opened for addition, and colored solid cleaning agent 26 can be selected to achieve visual cleaning and consumable addition indication. Since the position of the liquid outlet 22 is lower than the position of the second water inlet 21 and higher than the bottom of the storage cavity 23, this utility model can use the height of the liquid outlet 22 to control the soaking and release speed of the solid cleaning agent 26. Furthermore, since the second water inlet 21 is located at the top of the storage cavity 23, there is a water level difference h between the position of the liquid outlet 22 and the second water inlet 21 (e.g., h). Figure 12 (As shown). The top cover and the box body 24 adopt a sealed design, which can ensure that the solution can still be added to the mixer 1 even when the storage box 2 is placed far below the mixer 1, and that the inlet and outlet water volumes are consistent in the water outlet state, controlling the release amount of cleaning agent and the stability of the water level line each time, and ensuring the anti-siphon water level difference.

[0048] This invention relates to a detergent slow-release device, which can be applied to urinals, but is not limited thereto. When the detergent slow-release device of this invention is applied to a urinal, the first inlet 11 of the mixer 1 can be connected to the inlet end of the solenoid valve 4 used to control the flushing of the urinal, and the mixing outlet 12 of the mixer 1 can be connected to the inlet end of the flushing nozzle 5 of the urinal, such as... Figure 16-19 As shown.

[0049] When the urinal starts flushing, the solenoid valve 4 opens, and water enters the mixer 1. In the inlet area 15 of the mixer 1, water is divided: one stream flows to the mixing zone 16, and the other, after being throttled by the diverter 112, flows into the storage chamber 23 of the detergent container 2. This dissolves the solid detergent 26 in the storage chamber 23. The dissolved solution, driven by the water flow, is output and enters the mixing zone 16 of the mixer 1 to mix with the water. It then exits from the mixing outlet 12 and flows to the flushing nozzle 5 to clean and disinfect the urinal's washing surface. Figure 14 As shown in the diagram, the arrows indicate the direction of water flow.

[0050] When the tap water supply is interrupted and negative pressure occurs in the inlet pipe, the mixer 1 draws in air through the flushing nozzle 5 to break the siphon, and the one-way valve 3 prevents backflow, thus achieving the first anti-siphon effect and preventing air from entering the storage box 2 and driving the liquid in the storage box 2 towards the inlet pipe. If the one-way valve 3 fails to prevent backflow, due to the inlet water level difference h in the storage box 2, a second anti-siphon effect can be achieved by utilizing the inlet water level difference h: when negative pressure occurs in the inlet pipe, the mixer 1 draws in air through the flushing nozzle 5 to break the siphon, and at the same time, some air enters the storage box 2 through the failed one-way valve 3. Under the action of the inlet water level difference h, the air entering the storage box 3 occupies the space above the liquid surface and is directly discharged from the second inlet 21. Figure 15 As shown in the diagram, the arrows indicate the direction of airflow. This prevents liquid from the storage container 2 from flowing into the water inlet area 15, thus ensuring that the detergent solution does not contaminate the water inlet pipe.

[0051] Therefore, this utility model directly uses water power to automatically and quantitatively release cleaning agents, which can reduce the amount of cleaning agent used. Furthermore, it eliminates the need for additional moving parts, resulting in a simpler overall structure, lower cost, and lower failure rate.

[0052] Please see Figures 1-19 As shown, this utility model provides a urinal, including a urinal body 6, which is provided with a flushing nozzle 5, and also includes a detergent slow-release device as described above. The feature is that the liquid outlet 12 is connected to the inlet end of the flushing nozzle 5.

[0053] In this embodiment, a receiving groove 61 is provided on the top of the back side of the urinal body 6, and the detergent slow-release device is placed in the receiving groove 61; it also includes a solenoid valve 4, which controls whether the detergent slow-release device is inlet water, that is, the inlet end of the solenoid valve 4 is connected to the first water inlet 11 of the mixer 1. The solenoid valve 4 can be replaced by a mechanical valve or an electric valve of other structures.
