Description

Technical Field

[0001] The utility model relates to the field of solenoid valves, in particular to a novel solenoid valve controlled by a magnet. Background Art

[0002] As an indispensable sanitary ware in modern families, the continuous optimization of the design and function of toilets is an important aspect of improving the quality of life. Traditional toilets are usually equipped with a water tank for storing the water required for flushing, but such a design often makes the toilet larger in size, occupies more space, and is not conducive to the use of small-sized or space-limited families. Therefore, in order to reduce the volume of the toilet and improve its space utilization efficiency, a waterless toilet has been gradually developed on the market. This kind of toilet is directly connected to the water source and supplies water immediately when flushing is needed, effectively reducing the volume and meeting the demand for efficient space utilization in modern homes.

[0003] However, in the design of waterless toilets, the valve controlling the opening and closing of flushing has become a key component. In the prior art, most of these valves adopt a mechanical control structure. Although the basic opening and closing functions can be realized, there are disadvantages such as slow response and easy failure, which affect the user experience and the long-term reliability of the product.

[0004] In view of the above problems, this patent proposes an innovative solution, that is, to use a novel solenoid valve to replace the traditional mechanical valve. The solenoid valve uses the electromagnetic principle to achieve fast opening and closing control, reduces the failure rate, and thus significantly improves the overall performance and user satisfaction of the waterless toilet.

A first control valve port and a second control valve port are arranged on the valve body. One end of the swing arm is connected to the output shaft of the motor, and the other end of the swing arm controls the position of the magnet. When the swing arm rotates to the first position, the magnet aligns with the first moving iron core for adsorption, the first plug and the first control valve port are separated, and the first magnetic plug component is opened. When the swing arm rotates to the second position, the first spring pushes the first moving iron core, so that the first plug and the first control valve port are closed, the magnet aligns with the second moving iron core for adsorption, the second plug and the second control valve port are separated, and the second magnetic plug component is opened.

The first annular water channel, the second annular water channel and the water inlet pipe are communicated with each other.

[0013] A further alternative solution of the present utility model is as follows: both the first sealing mechanism and the second sealing mechanism include an elastic diaphragm seal and an anti-blocking needle spring. When the first plug moves downward to block the first control valve port or the second plug moves downward to block the second control valve port, the diaphragm seal will be pressed downward to block the first water outlet pipe or the second water outlet pipe.

[0024] The present utility model will be further described in detail below with reference to the embodiments in the drawings.

[0025] As Figures 1-7As shown in the figure, a new type of solenoid valve controlled by a magnet includes a control part 1 and a valve body 2. A stepper motor 3, a swing arm 4, a magnet 5, a first magnetic plug component and a second magnetic plug component are arranged in the control part 1. The first magnetic plug components each include a first moving iron core 6 and a first spring 7. The second magnetic plug components each include a second moving iron core 8 and a second spring 9. The lower end of the first moving iron core 6 is a first plug 10. The lower end of the second moving iron core 8 is a second plug 11. A first control valve port 12 and a second control valve port 13 are arranged on the valve body 2. One end of the swing arm 4 is connected to the output shaft of the motor, and the other end of the swing arm 4 controls the position of the magnet 5. When the swing arm 4 rotates to the first position, the magnet 5 aligns with the first moving iron core 6 for adsorption, the first plug 10 and the first control valve port 12 are separated, and the first magnetic plug component is opened. When the swing arm 4 rotates to the second position, the first spring 7 pushes the first moving iron core 6, so that the first plug 10 and the first control valve port 12 are closed, the first magnetic plug component is closed, the magnet 5 aligns with the second moving iron core 8 for adsorption, the second plug 11 and the second control valve port 13 are separated, and the second magnetic plug component is opened. The closing of the first magnetic plug component and the second magnetic plug component realizes the opening and closing of the first water outlet pipe 19 and the second water outlet pipe 20 in the valve body 2, thereby realizing the control of the opening and closing of the pulse valve.

[0026] The swing arm 4 is cleverly arranged in the movable cavity 14. Through its flexible movement, it drives the magnet 5 to move precisely in the movable cavity 14. The movement of the magnet 5 directly determines the open or closed state of the first magnetic plug component and the second magnetic plug component, thereby realizing the effective control of the water flow. In order to further enhance the movement stability and accuracy of the swing arm 4, a long strip-shaped magnet movable cavity 15 is specially arranged at one end of the swing arm 4. The magnet 5 can move freely in this movable cavity. And under the push of the swing arm 4, when the magnet 5 is attracted by the first moving iron core 6 or the second moving iron core 8, it will automatically move to the corresponding position quickly and accurately along the magnet movable cavity 15. This design not only makes the adsorption action of the magnet 5 faster and more accurate, but also greatly improves the response speed and control accuracy of the opening and closing of the valve body 2. At the same time, it also makes the design of the swing arm 4 have a higher error tolerance rate.

[0027] To ensure the stability of the swing arm 4 during movement and the accuracy of positioning, limiting grooves 16 are carefully provided on both sides of the swing arm 4. At the same time, two limiting protrusions 17 are correspondingly provided in the movable cavity 14. When the swing arm 4 moves to a predetermined position, the limiting grooves 16 and the limiting protrusions 17 will closely cooperate to achieve the limiting and positioning functions of the swing arm 4, ensuring that the swing arm 4 can stably remain in the predetermined position after swinging. Both the first moving iron core 6 and the second moving iron core 8 are made of magnetic materials and elastic materials. This design not only enables the plug part (made of elastic material) to have good sealing performance and durability, but also enables the magnetic material to fully exert its magnetic attraction and cooperate with the magnet 5 to achieve precise adsorption actions.

[0028] The valve body 2 is also exquisitely designed and fully functional, including a water inlet pipe 18, a first water outlet pipe 19, a second water outlet pipe 20, a first sealing mechanism 21, and a second sealing mechanism 22. The water inlet pipe 18 is cleverly arranged between the first water outlet pipe 19 and the second water outlet pipe 20 to achieve reasonable distribution of water flow. The first sealing mechanism 21 is aligned with the first water outlet pipe 19 and controls its opening and closing state; similarly, the second sealing mechanism 22 is aligned with the second water outlet pipe 20 and controls its opening and closing state. This design enables the valve body 2 to achieve precise control of different water outlet paths. To further enhance the functionality and practicality of the valve body 2, a first annular water channel 23 is cleverly provided outside the first water outlet pipe 19; similarly, a second annular water channel 24 is provided outside the second water outlet pipe 20. Both of these annular water channels are connected to the water inlet pipe 18 to achieve more complex and diverse water flow control effects. Both the first sealing mechanism 21 and the second sealing mechanism 22 adopt an advanced elastic diaphragm seal 25 and anti-blocking needle spring 26 design. The anti-blocking needle part of the anti-blocking needle spring 26 is cleverly inserted into the through hole of the elastic diaphragm seal 25, and the spring part is arranged above the elastic diaphragm seal 25. This design not only avoids the risk of the through hole of the elastic diaphragm seal 25 being blocked, but also enables the spring to continuously push the elastic diaphragm seal 25 to tightly block the first water outlet pipe 19 or the second water outlet pipe 20, achieving a more reliable and durable sealing effect. When the first plug 10 moves downward and blocks the first control valve port 12, or when the second plug 11 moves downward and blocks the second control valve port 13, under the action of water pressure, the elastic diaphragm seal 25 will tightly press down and block the corresponding water outlet port. On the contrary, when the first plug 10 or the second plug 11 moves upward, the elastic diaphragm seal 25 will also move upward accordingly and open the corresponding water outlet port, achieving flexible and reliable water flow control.

[0029] To further enhance the safety and practicality of the valve body 2, an anti-siphon device 27 is specifically provided on the housing of the valve body 2. This device can effectively avoid the risk of the water in the outlet pipe being siphoned back into the inlet pipe 18 when the inlet pipe 18 generates back-siphon, thus causing pollution. In addition, a feminine wash water pipe 28 is cleverly provided on the valve body 2 and is connected to the inlet pipe 18. This design makes the function of the solenoid valve more diverse and practical, and can meet the usage requirements in different scenarios.

[0030] The above has introduced in detail a novel solenoid valve controlled by a magnet provided by the present utility model. Specific examples are used in this article to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the present utility model and its core idea. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and modifications can still be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
