Detailed Implementation

[0031] 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 protection scope of the present utility model.

[0032] For reference as follows Figure 1-8 The present invention will be described as follows:

[0033] Example: This application is an improvement based on the applicant's prior patent application (CN201611013612.X).

[0034] A foot valve with flow regulation function includes a valve body 1, a mounting cavity 2 inside the valve body 1, and a spring 3, a plunger 4, a middle seat 5, and a pressure cap 6 arranged sequentially from the inside to the outside of the mounting cavity 2. The pressure cap 6 is threadedly connected to the mounting cavity 2. The middle seat 5 is restricted between the pressure cap 6 and the valve body 1. A valve stem 7 is connected inside the pressure cap 6 and the middle seat 5. The rear end of the valve stem 7 is connected to the plunger 4, and the front end of the valve stem 7 abuts against the pedal 8.

[0035] The rear end of the pedal 8 forms two connecting arms 9. One connecting arm 9 is hinged to the valve body 1, and the other connecting arm 9 is rotatably connected to a pressure roller 10 that abuts against the valve stem 7.

[0036] The valve body 1 is provided with a connecting groove 11, the connecting arm 9 extends into the connecting groove 11, and also includes a connecting hole 12 that passes through the valve body 1 and the connecting arm 9. A bolt 13 is connected in the connecting hole 12, and an anti-loosening nut 14 is connected to the end of the bolt 13.

[0037] The core function of the connecting groove 11 is to strengthen the connecting structure through spatial enclosure. When the connecting arm 9 of the pedal 8 extends into the connecting groove 11, the inner wall of the connecting groove can form multi-directional constraints on the connecting arm.

[0038] In traditional structures, the connecting arm is exposed and unrestrained. When stepped on, the connecting arm will swing and sway due to the torque, which can easily lead to deformation of the connection part after long-term use. However, the two side walls of the connecting groove 11 can restrict the displacement of the connecting arm 9, so that the stepping force is mainly transmitted along the axial direction of the connecting arm, reducing the additional non-axial torque and reducing the risk of fatigue damage to the connecting arm.

[0039] From a structural protection perspective, the connecting groove 11 isolates the connecting arm 9 from the external environment, preventing external objects from directly colliding with the connecting arm or hinge. In traditional exposed structures, collisions may cause the connecting arm to bend or the hinge axis to shift. However, the enclosure of the connecting groove allows the valve body 1 to bear the external impact force first, indirectly protecting the connection node between the connecting arm and the valve body. This reduces structural failure caused by collisions and extends the overall service life.

[0040] The connection method, which uses bolts 13 penetrating the valve body 1 and connecting arm 9 in conjunction with anti-loosening nuts 14, significantly improves the connection strength and stability compared to traditional pin connections. Bolts are stronger than ordinary pins, are less prone to bending or breakage under long-term stress, and have a longer service life.

[0041] A surrounding plate 15 extends forward from the front edge of the valve body 1, and the ends of the pressure roller 10 and valve stem 7 are located within the area enclosed by the surrounding plate 15. This physical isolation creates a closed area, providing multi-dimensional protection for the ends of the pressure roller 10 and valve stem 7.

[0042] The area enclosed by the enclosure 15 completely isolates the contact point between the pressure roller and the valve stem (i.e., the critical node for force transmission) from the external environment. In everyday use, accidental contact from floor cleaning tools (such as mops and brooms) or pedestrians' feet will be blocked by the enclosure 15, preventing direct impact on the pressure roller 10 or the end of the valve stem 7. In conventional structures, this part is exposed, and contact may cause the pressure roller to shift, the valve stem to bend, or even disrupt the contact between the two. The enclosure 15 reduces the risk of such physical damage.

[0043] The connecting groove 11 extends through the upper and front sides of the valve body 1.

[0044] From the perspective of motion trajectory, the through-type connecting groove makes the relative position of the rotation axis of pedal 8 (i.e., the axis where bolt 13 is located) and the valve body more reasonable. When the valve body is installed horizontally, the rotation center of pedal 8 is located in the through area of ​​the connecting groove. When rotating upward, the connecting arm 9 can swing freely along the upper opening of the connecting groove until pedal 8 forms a 90° vertical position with the ground. Traditional non-through-type connecting grooves limit the swing angle (usually the maximum swing angle does not exceed 45°), causing the pedal to always be in a tilted state.

[0045] From a cleaning convenience perspective, the pedal 8, when rotated vertically, completely frees up floor space. Cleaning personnel can use large tools such as floor scrubbers and vacuum cleaners to directly clean the area under the pedal, avoiding the formation of unsanitary corners (such as accumulated dust and sewage) under the pedal in traditional structures.

[0046] The valve body 1 is provided with an inlet channel 16 and an outlet channel 17 that communicate with the mounting cavity 2. The plunger 4 is composed of a sealing section and an outlet section. The diameter of the sealing section is larger than the diameter of the outlet section. The diameter of the sealing section is equal to the inner diameter of the mounting cavity 2. Under the action of the spring 3, the sealing section is in a state of blocking the inlet channel 16 and the middle seat 5. The middle seat 5 is provided with an outlet hole 18 that communicates with the outlet channel 17.

[0047] Under the action of spring 3, the sealing section is in a blocked state. At this time, the sealing section is tightly fitted with the inner wall of the mounting cavity 2, which can effectively prevent water in the water inlet channel 16 from entering the middle seat 5 area, ensuring that there will be no water leakage when not in use.

[0048] When pedal 8 is pressed, pressure roller 10 applies pressure to valve stem 7. Valve stem 7 pushes plunger 4 backward against the elastic force of spring 3, causing the sealing section to leave the blocking position. The channel between water inlet channel 16 and middle seat 5 is opened, allowing water to flow into water outlet channel 17 through water outlet hole 18 on middle seat 5. Due to the difference in diameter between the sealing section and the water outlet section, the transition from blocking to conduction can be smoothly achieved during the movement of plunger 4, ensuring the stability of water flow.

[0049] The valve body 1 has a mounting port 19 on its side wall that communicates with the water inlet channel 16, and a flow regulating valve 20 is installed in the mounting port 19. This configuration allows the user to adjust the water flow rate according to actual needs. The flow regulating valve 20 can control the amount of water entering the water inlet channel 16 by changing the opening degree of its own valve core.

[0050] Pipe fittings 21 are connected to the water inlet channel 16 and the water outlet channel 17 respectively. The main function of the pipe fittings 21 is to connect the water inlet channel 16 and the water outlet channel 17 to the external water pipe.

[0051] A fixing part 22 is provided on the lower side of the valve body 1, and a fixing hole 23 is provided on the fixing part 22. This is a key structure for achieving stable installation of the valve body 1. When installing the foot valve, the valve body 1 can be fixed to the ground or other mounting surface through the fixing hole 23. If bolts are used to connect to the mounting surface through the fixing hole 23, it can effectively prevent the valve body 1 from shifting or shaking due to external forces such as stepping during use.

[0052] 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 spirit and principles of the present utility model should be included within the protection scope of the present utility model.
