Description

Technical Field

[0001] This utility model relates to the field of bathroom technology, and in particular to a flushing drive device. Background Technology

[0002] Most existing bathroom flushing devices still rely on traditional mechanical buttons or manual operation, which poses hygiene risks due to contact operation.

[0003] Furthermore, while some automatic flushing devices achieve non-contact control through sensors, their drive structures often employ electric motors or hydraulic systems, resulting in complex structures, high energy consumption, and high maintenance costs. For example, electric motor drives are susceptible to moisture damage, hydraulic systems pose a risk of leakage, and their response speed is slow. Additionally, the lack of efficient pneumatic pressure relief mechanisms in existing technologies leads to delayed reset or incomplete operation after flushing, affecting the device's stability and lifespan. Utility Model Content

[0025] like Figures 1 to 6 As shown, this solution provides a flushing drive device.

[0026] Please see Figures 1 to 6 The device includes: a housing 1, a guide member 3, and an airbag 4. The guide member 3 is movably inserted into the housing 1, and the airbag 4 is installed inside the guide member 3 to activate it. One end of the guide member 3 extends downward and is provided with a pressure rod 31 for triggering the switch of the drain valve A. Specifically, the pressure rod 31 is bent at a right angle, and one end is connected to the guide member 3. When the pressure rod 31 moves downward, the other end of the pressure rod 31 abuts against the switch of the drain valve A. One end of the housing 1 has a guide groove 11 that matches the pressure rod 31. An elastic reset member 2 is installed between the guide member 3 and the housing 1. Specifically, the elastic reset member 2 is a compression spring, one end of which abuts against the housing 1, and the other end abuts against the guide member 3.

[0027] The system also includes a control system 8, which contains a sensing module 81, a second air guide 84, and a connecting pipe 7. The sensing module 81 is a direct application of existing technology, such as an infrared sensor and a circuit board (not shown in the figure), and will not be described in detail here. One end of the second air guide 84 is equipped with an air pump 82, and the other end is equipped with a pressure relief solenoid valve 83. One end of the connecting pipe 7 is connected to the second air guide 84, and the other end is connected to the airbag 4. An exhaust port 85 is also provided at one end of the control system 8. Specifically, the second air guide 84 is made of rubber and has an air guide channel 841 formed within it. The air pump 82 is mounted at the upper end of the air guide channel 841, and the pressure relief solenoid valve 83 is mounted at the lower end of the air guide channel 841. The other end of the pressure relief solenoid valve 83 is connected to the exhaust port 85. Both the air pump 82 and the pressure relief solenoid valve 83 are direct applications of existing technology, and their working principles will not be described in detail here.

[0028] Please see Figures 1 to 3 It also includes a first air guide 6, which has an air inlet 60 at its upper end and an air outlet 61 at its lower end. The lower end of the first air guide 6 is fixedly inserted into the airbag 4, and the upper end of the first air guide 6 is engaged with the airbag 4. Specifically, the lower end of the guide 3 has a limiting hole 32, and the lower end of the airbag 4 extends toward the limiting hole 32 with a buckle 41, which cooperates with the limiting hole 32. The buckle 41 is arrow-shaped, and a groove is formed between the buckle 41 and the airbag 4. The edge of the limiting hole 32 of the guide 3 is engaged in the groove. A connecting pipe 7 is fixedly inserted into the air inlet 60, and the connecting pipe 7, the air inlet 60, the air outlet 61, and the airbag 4 are connected.

[0029] Please see Figures 1 to 3 It also includes an upper cover 5, which is fixedly mounted on the housing 1. The upper cover 5 has a fixing groove 51, and the first air guide 6 is fixedly embedded in the fixing groove 51. One end of the upper cover 5 also has a notch 52 for cooperating with the pressure rod 31.

[0030] Please see Figure 5 and Figure 6 The outer circumferential surface of the housing 1 is fitted with a clamp 12, and the housing 1 is installed on the drain valve A via the clamp 12. The clamp 12 is a direct application of existing technology, and its working principle will not be described in detail here. By setting the clamp 12, it is convenient to install the drive device on the drain valve A.

[0031] Working principle: When the sensing module 81 detects the user trigger signal, it starts the air pump 82. The air pump 82 sends gas into the airbag 4 through the air channel 841 of the second air guide 84 and the connecting pipe 7, via the air inlet 60 and air outlet 61 of the first air guide 6. As the gas is injected, the internal pressure of the airbag 4 increases and it expands, pushing the guide 3 to move downward along the guide groove 11 of the housing 1. When the guide 3 moves downward, the pressure rod 31 at its end presses down synchronously, triggering the switch of the drain valve A and starting the flushing process.

[0032] When the preset flushing time is reached, the air pump 82 is turned off and the pressure relief solenoid valve 83 is opened. The gas in the airbag 4 is quickly discharged through the exhaust port 85. At this time, the compression spring assembled between the guide 3 and the housing 1 releases its elastic potential energy, pushing the guide 3 to move upward and reset. The airbag 4 contracts to its initial state due to the gas discharge, and the pressure rod 31 disengages from the drain valve A switch, and the flushing process ends.

[0033] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
