Description

Technical Field

[0001] The utility model relates to the technical field of toilet drain valves, in particular to a drain valve structure. Background Art

[0002] In order to adapt to toilets of different heights, the drain valves currently installed in toilets are designed with valve bodies of various heights and specifications. The height of the valve body is relatively fixed and single, and the versatility is poor. In addition, without knowing the height of the customer's toilet tank, it is often not known which size and specification of the drain valve height to use for matching, and it is impossible to adjust any position according to actual needs, which brings a heavy workload to matching and replacement. What is more serious is that it is necessary to develop a variety of drain valve bodies of different heights, which greatly wastes production resources and labor costs. The float on the drain valve is integrated with other parts. If it is damaged during use, the entire drain valve cannot be used, resulting in a waste of resources. According to the different models of toilet tanks and drain valves, the size of the float is also different. The size of the float also has a certain influence on the opening or closing of the drain valve (the float is connected to the rod of the control valve. When the water level is high or low, the float is in a higher or lower position, the airtightness of the valve will be poor, and water leakage will occur). For this reason, we propose a drain valve structure that can adapt to the height of toilet tanks of different models and the depth of the float immersion water can be adjusted. Utility Model Content

[0032] The rubber tube 43 and the lifting rod 42 are fixedly connected, and the lifting rod 42 and the tube 1 41 are gap connected.

[0033] The immersion mechanism 6 includes a hose 1 61 installed on the float 13, one end of the hose 1 61 is connected to the rubber bag 5, and the other end is installed with a Luer connector 1 62. The hose 1 61 is connected to a sleeve 63, and the other end of the sleeve 63 is connected to a hose 2 64. One end of the hose 2 64 is installed with a Luer connector 2 65, and the other end is sleeved with a gravity ball 67. Connectors 3 66 corresponding to the Luer connector 1 62 and the Luer connector 2 65 are respectively arranged on both sides of the sleeve 63. The sleeve 63 also includes a pressure control mechanism 7 installed in the sleeve 63, and the pressure control mechanism 7 forms a positive pressure or a negative pressure in the sleeve 63.

[0034] The Luer connector has excellent airtightness and quick installation, making it more convenient and stable.

[0035] The pressure control mechanism 7 includes an air cylinder 71 installed on the sleeve 63, a piston 72 is installed in the air cylinder 71, a pressure rod 73 is installed on the piston 72, a fixed block 74 is installed on the sleeve 63, a spring 75 is installed on the fixed block 74, one end of the spring 75 is connected to the fixed block 74, and the other end is connected to the top of the pressure rod 73. It also includes a conversion mechanism 8 installed on the sleeve 63, and the conversion mechanism 8 controls the volume of water in the rubber bag 5.

[0036] The conversion mechanism 8 passes through a rotating rod 81 installed on the sleeve 63 , a sealed ball 82 is fixed on the rotating rod 81 , the sealed ball 82 is located inside the sleeve 63 and is tightly attached to the inner wall of the sleeve 63 , and a one-way valve 83 is installed on the sealed ball 82 .

[0037] A scale 44 is provided on the lifting rod 42, so that the height at which the drain valve needs to be set can be intuitively understood, which is more convenient during subsequent replacement or maintenance.

[0038] The working principle of the utility model is as follows: the whole structure is fixed inside the toilet tank by the fixing rod 3, and then the valve body 1 is manually stretched upwards, and the larger friction between the rubber tube 43 and the tube 1 41 fixes the valve body 1 at a suitable height. Compared with the traditional straight tube, the bellows 2 can also automatically adapt to the height adjustment of the lifting rod 42, and then the float 13 is placed on the water surface, and the gravity ball 67 drives one end of the hose 2 64 to always be located in the water. Then, the positional relationship between the float 13, the control rod 11 and the valve body 1 is determined. This is a basic skill for technicians in this field. If it is necessary to immerse the float 13 to a certain depth of the water surface, rotate the rotating rod 81, and the rotating rod 81 changes the direction of the one-way valve 83 through the sealing ball 82, so that water can only be injected into the rubber bag 5 through the hose 1 61. At this time, the staff member pinches the hose 2 64 with one hand and presses the pressure rod 73 with the other hand, and the pressure rod 73 drives the piston The piston 72 is pressed downward, and under the pressure of the piston 72, the water in the sleeve 63 is squeezed into the rubber bag 5. Then, the rotating rod 81 is rotated to loosen the hose 2 64. Under the action of the spring 75, the pressing rod 73 is reset, driving the piston 72 to move upward. The negative pressure generated causes the sleeve 63 to be refilled with water. By repeating the above steps, the water in the rubber bag 5 can be increased, thereby making the rubber bag 5 heavier as a whole, pressing the float 13 downward, and increasing the depth of the float 13 immersed in the water. When it is necessary to reduce the immersion depth, it is only necessary to rotate the rotating rod 81, the rubber bag 5 returns to its original state, squeeze the internal water, reduce the water in the rubber bag 5, and the float 13 rises a certain height from the water surface. When it is just used, the one-way valve 83 can be closed to make the immersion mechanism 6 part completely in the water. The pressing rod 73 is continuously pressed, and the pressing rod 73 discharges the gas in the hose 2 64 and replenishes water at the same time, so that the use effect is better.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
