Pedal valve with touch-proof structure

Abstract

This utility model relates to the field of anti-touch technology, specifically a foot valve with an anti-touch structure. It includes a foot valve body, a pedal body fixedly connected to one side of the foot valve body, and an outer shell on one side of the foot valve body. A fixing post is fixedly connected to the inner cavity of the outer shell, and an anti-accidental touch mechanism and a limiting component are provided within the inner cavity of the outer shell. This utility model, by pressing down on the foot pedal, causes the moving component to move downwards. The different angles between the two fixing rods and the two second connecting rods create different resistances as the moving component moves downwards. This difference in resistance achieves the anti-accidental touch effect while allowing users to clearly distinguish whether the pedal body has been successfully pressed. Through a two-stage pressing mechanism, the valve can be opened and closed, enabling users to clearly perceive whether the pedal body has been successfully pressed and effectively protecting the pedal body from accidental touch.

Description

Technical Field

[0001] This utility model relates to the field of anti-touch, specifically a foot valve with an anti-touch structure. Background Technology

[0002] A foot valve is a valve device that uses foot pedals to mechanically or hydraulically / pneumatically control the opening and closing of media such as water, air, and oil. Its core design purpose is to achieve rapid opening and closing of the valve without the need for hand operation. It is suitable for scenarios with high hygiene requirements, where both hands are occupied, or where frequent operation is required. Anti-touch refers to the mechanical, electronic, or structural design to prevent the foot valve from being malfunctioned due to accidental stepping, falling objects, or environmental interference, ensuring that the valve is only triggered by active and intentional operation.

[0003] In existing technologies, foot valves can be used in various scenarios, but they are most commonly found in bathrooms. By pressing the foot valve, it can be opened and water can flow out, facilitating flushing of the squat toilet. Generally, a box or shell is placed on its surface to prevent accidental activation of the foot valve. However, when using a box or shell to block the foot valve and prevent accidental activation, the box or shell needs to be moved and removed before and after use. This not only increases the inconvenience of using the foot valve, but also makes the box or shell easy to lose, thus reducing the effectiveness of preventing accidental activation. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, when using objects such as boxes or housings to shield the foot valve and prevent accidental activation, it is necessary to move and remove the housing or box before and after use. This not only increases the inconvenience of using the foot valve, but also makes the housing or box easy to lose, thereby reducing the effectiveness of preventing accidental activation of the foot valve. This utility model proposes a foot valve with an anti-touch structure.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a foot valve with an anti-touch structure, including a foot valve body, a pedal body fixedly connected to one side of the foot valve body, an outer shell provided on one side of the foot valve body, a fixing column fixedly connected to the inner cavity of the outer shell, and an anti-accidental touch mechanism and a limiting component provided in the inner cavity of the outer shell.

[0006] The anti-accidental touch mechanism includes a connecting column, one end of which is fixedly connected to one side of a fixed column. A sliding rod is rotatably connected to the surface of the connecting column, and a connecting block is fixedly connected to the surface of the connecting column. A first spring is fixedly connected to one side of the connecting block, one end of which is fixedly connected to one side of the sliding rod. A roller is rotatably connected to the inner cavity of the sliding rod, a moving component is fixedly connected to one side of the roller, a connecting plate is fixedly connected to one side of the moving component, and a push rod is fixedly connected to one side of the moving component.

[0007] Preferably, the movable component includes a first connecting rod, one side of which is fixedly connected to the bottom of a connecting plate, and a fixing rod is fixedly connected to one side of the first connecting rod. Two fixing rods are provided, and a connecting plate is fixedly connected to one side of each of the two fixing rods. A second connecting rod is fixedly connected to one side of each connecting plate. Two second connecting rods are provided, and the surface of the roller is slidably connected to the surface of the movable component.

[0008] Preferably, the limiting component includes a limiting block, one side of which is fixedly connected to one side of the push rod, and a limiting groove is formed in the inner cavity of the outer shell, with one side of the limiting block slidably connected to the inner cavity of the limiting groove.

[0009] Preferably, a pressing plate is fixedly connected to the top of the connecting plate, and a reinforcing ring block is fixedly connected to the surface of the pressing plate, with one side of the reinforcing ring block fixedly connected to the top of the connecting plate.

[0010] Preferably, a reinforcing rod is fixedly connected to the inner cavity of the limiting groove, and the surface of the reinforcing rod is slidably connected to the inner cavity of the limiting block.

[0011] Preferably, a second spring is fixedly connected to the inner cavity of the limiting groove, one end of the second spring is fixedly connected to one side of the limiting block, and the surface of the second spring is sleeved on the surface of the reinforcing rod.

[0012] Preferably, a reinforcing plate is fixedly connected to the surface of the fixed column, and one side of the reinforcing plate is fixedly connected to the inner cavity of the outer shell.

[0013] The advantages of this utility model are:

[0014] This invention utilizes the pressure of a foot pedal to move a movable component downwards. The different angles between the two fixed rods and the two second connecting rods create varying resistance as the component moves downwards. This difference in resistance prevents accidental activation while allowing users to clearly distinguish whether the pedal is being used correctly. By employing a two-stage pressure-to-open valve design, users can not only clearly perceive whether the pedal is being used correctly but also effectively protect it from accidental activation. This solves the problem of needing to move and remove the casing or housing before and after use when the foot pedal is blocked by objects, increasing the inconvenience of using the foot pedal and making the casing or housing prone to loss, thus reducing the effectiveness of preventing accidental activation.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses a foot valve with an anti-touch structure. (See also...) Figure 1 and Figure 2 A foot valve with an anti-touch structure includes a foot valve body 1, a pedal body 9 fixedly connected to one side of the foot valve body 1, an outer shell 2 provided on one side of the foot valve body 1, a fixing post 7 fixedly connected to the inner cavity of the outer shell 2, and an anti-accidental touch mechanism 5 and a limiting component 6 provided in the inner cavity of the outer shell 2.

[0025] The anti-accidental touch mechanism 5 includes a connecting post 506, one end of which is fixedly connected to one side of a fixed post 7. A sliding rod 501 is rotatably connected to the surface of the connecting post 506. A connecting block 505 is fixedly connected to the surface of the connecting post 506. A first spring 504 is fixedly connected to one side of the connecting block 505. One end of the first spring 504 is fixedly connected to one side of the sliding rod 501. A roller 502 is rotatably connected to the inner cavity of the sliding rod 501. A moving component 507 is fixedly connected to one side of the roller 502. A connecting plate 503 is fixedly connected to one side of the moving component 507. A push rod 508 is fixedly connected to one side of the moving component 507.

[0026] The pedal body 9, connected to the foot valve body 1, allows the foot valve body 1 to open and close when the pedal body 9 is subjected to force. The fixing post 7, connected to the outer casing 2, supports the connecting post 506, ensuring its smooth operation. The connecting post 506 connects to the sliding rod 501. Simultaneously, the connecting plate 503 connects to the moving component 507, providing a connection. When the connecting plate 503 is subjected to force, it drives the moving component 507 downwards, separating the sliding rod 501 to both sides. Under force, the sliding rod 501, due to its connection with the connecting post 506, can rotate along the surface of the connecting post 506. Meanwhile, the connecting block 505, through its connection with the sliding rod 501 and the connecting post 506, provides a connection for the first spring 504. When the sliding rod 501 is spread out and rotates along the connecting post 506... When the surface of the connecting post 506 moves, it is restricted by the elasticity of the first spring 504. When the sliding rod 501 moves a certain distance, it will reset due to the elasticity of the first spring 504. If you want the sliding rod 501 to continue moving, you need to press the connecting plate 503 again. At the same time, the moving component 507 is connected to the push rod 508 and provides a connection for the push rod 508. Both the foot valve body 1 and the outer shell 2 can be connected to the ground to achieve stable use. The foot valve body 1 is a mechanical device that controls the flow of fluid by pressing the pedal body 9 with the foot. Its entire working process can be divided into four main stages: power input, force transmission, valve action and reset, forming a complete mechanical control system. Therefore, the foot valve body 1 is existing technology in this field and will not be described in detail here.

[0027] Reference Figure 2 and Figure 3The movable component 507 includes a first connecting rod 5071, one side of which is fixedly connected to the bottom of a connecting plate 503. Two fixing rods 5072 are fixedly connected to one side of the first connecting rod 5071. A connecting plate 5073 is fixedly connected to one side of each fixing rod 5072. Two second connecting rods 5074 are fixedly connected to one side of each connecting plate 5073. The surface of a roller 502 is slidably connected to the surface of the movable component 507. The first connecting rod 5071 connects to and provides a connection between the two fixing rods 5072, while the connecting plate 5073, through its connection to the two fixing rods 5072, provides a connection between the two second connecting rods 5074, enabling their smooth operation. The angle formed by the two second connecting rods 5074 is smaller than the angle formed by the two fixed rods 5072. This allows the second connecting rod 5074 to slide to the inside of the sliding rod 501 with less resistance when it moves downward under force and contacts the roller 502. However, when the angle formed by the two fixed rods 5072 contacts the roller 502, the angle formed by the two fixed rods 5072 is larger than the angle formed by the two second connecting rods 5074, resulting in greater resistance. At this point, a greater force needs to be applied to the connecting plate 503 to allow the roller 502 to continue expanding. People can then judge whether the pedal body 9 is being pressed smoothly by applying different forces when the connecting plate 503 is pressed, and can clearly perceive whether the connecting plate 503 is accidentally pressed.

[0028] Reference Figure 2 and Figure 4 The limiting component 6 includes a limiting block 601. One side of the limiting block 601 is fixedly connected to one side of the push rod 508. A limiting groove 602 is opened in the inner cavity of the outer shell 2. One side of the limiting block 601 is slidably connected to the inner cavity of the limiting groove 602. The push rod 508 is connected to the limiting block 601 and provides a connecting function. At the same time, the opening of the limiting groove 602 allows the limiting block 601 to slide in its inner cavity. When the push rod 508 is raised or lowered, the setting of the limiting groove 602 and the limiting block 601 makes it more stable and less prone to tilting.

[0029] Reference Figure 1 and Figure 2A pressing plate 3 is fixedly connected to the top of the connecting plate 503. A reinforcing ring block 4 is fixedly connected to the surface of the pressing plate 3. One side of the reinforcing ring block 4 is fixedly connected to the top of the connecting plate 503. The connecting plate 503 is connected to the pressing plate 3 and provides a connection for the pressing plate 3. The setting of the pressing plate 3 can increase the contact area when people's feet come into contact with objects, making it easier to press the pressing plate 3. The reinforcing ring block 4 is connected to the pressing plate 3, which further strengthens the connection between the pressing plate 3 and the connecting plate 503, making the connection more stable and reducing the possibility of the pressing plate 3 tilting or breaking when it is pressed.

[0030] Reference Figure 2 and Figure 5 A reinforcing rod 10 is fixedly connected to the inner cavity of the limiting groove 602. The surface of the reinforcing rod 10 is slidably connected to the inner cavity of the limiting block 601. The limiting groove 602 is connected to the reinforcing rod 10 and provides a connection function for it. The reinforcing rod 10 is connected to the limiting block 601, so that the limiting block 601 can move along the surface of the reinforcing rod 10. This allows the limiting block 601 to limit the push rod 508 while maintaining high stability.

[0031] Reference Figure 2 and Figure 5 The inner cavity of the limiting groove 602 is fixedly connected to a second spring 11. One end of the second spring 11 is fixedly connected to one side of the limiting block 601. The surface of the second spring 11 is sleeved on the surface of the reinforcing rod 10. The limiting groove 602 is connected to the second spring 11 and provides a connection for the second spring 11. The second spring 11 is connected to the limiting block 601 and can push it through its own elasticity when the limiting block 601 is reset and moved. When people accidentally touch it and need to return it, the elasticity of the second spring 11 can provide assistance, making the return process faster and smoother.

[0032] Reference Figure 2 and Figure 5 A reinforcing plate 8 is fixedly connected to the surface of the fixed column 7. One side of the reinforcing plate 8 is fixedly connected to the inner cavity of the outer shell 2. The outer shell 2 is connected to the reinforcing plate 8 and provides a connection for it. The reinforcing plate 8 further strengthens the connection between the fixed column 7 and the outer shell 2 through its connection with the fixed column 7, making it more stable when in use.

[0033] Working Principle: When using this device, the user first needs to press down on the pressure plate 3. After the pressure plate 3 is stressed, it transmits the force to the first connecting rod 5071 through its connection with the connecting plate 503. Once stressed, the first connecting rod 5071, through its connection with the fixed rod 5072 and the connecting plate 5073, drives the second connecting rod 5074 downwards. At this time, the second connecting rod 5074 contacts the roller 502 and pushes it downwards, causing the roller 502 to rotate to one side. Because the angle formed by the two second connecting rods 5074 is smaller than the angle formed by the two fixed rods 5072, the resistance encountered when the two second connecting rods 5074 contact the roller 502 is relatively small. It can slide into the inside of the sliding rod 501. When the second connecting rod 5074 slides into the inside of the sliding rod 501, the roller 502 can be pulled by the elasticity of the first spring 504. Therefore, the roller 502 will be retracted by the elasticity of the first spring 504 and stay on one side of the connecting plate 5073. If you want the second connecting rod 5074 to continue to move down, you need to apply a greater force to the foot plate 3 than before. This will drive the second connecting rod 5074 to continue to move down, so that the first connecting rod 5071 also approaches the inside of the sliding rod 501. This will drive the push rod 508 connected to the connecting plate 5073 to move synchronously, and make the push rod 508 press the pedal body 9, thereby completing the opening and closing of the foot valve body 1.

[0034] Furthermore, when someone accidentally steps on the pressure plate 3 and triggers the accidental touch protection, they need to use their toes to lift the pressure plate 3 and, through the aforementioned connection, move the second connecting rod 5074 upward. At this time, the connecting plate 5073 will push the roller 502, causing the sliding rod 501 to rotate away from the second connecting rod 5074. The second spring 11, connected to the limiting block 601, will, due to its own elasticity, pass through the limiting block 601 to push the push rod 508, thereby accelerating the upward movement of the second connecting rod 5074. When the second connecting rod 5074 moves out of the interior of the sliding rod 501 and re-contacts the surface of the roller 502, the sliding rod 501 will retract inward due to the elasticity of the first spring 504 and complete the closure again, thus protecting against the next accidental touch.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
