Description

Technical Field

[0001] The invention relates to the field of valves, and in particular to a double-layer tube straight-through push-to-close valve without a valve seat and a post-defecation anus cleaner. Background Art

[0002] The valve is the throat of the pipeline industry, and the valve seat is the throat of the throat. Traditional valves are generally divided into several categories according to the form of valve seats, such as stop valves, gate valves, ball (plug) valves, butterfly valves, etc. In addition, in order to prevent fluid leakage, valves generally use sealing packing or sealing diaphragm measures for the operating parts.

[0003] The above existing technologies have the following deficiencies: 1) Cavitation and erosion problems are long-standing problems in valves. For example, in the sugar industry, valves need to be lined with plastic to prevent contamination of the medium, but the wear of the valve seat and valve core, and the valve core and operating parts cannot be avoided; 2) In order to prevent external leakage, valves generally use sealing packing or sealing diaphragm measures on the operating parts, resulting in large resistance to the operating switch and inflexible braking; 3) The existing valve core structure cannot meet the needs of civil bathroom, catering, medical, chemical experiments, etc., which require valves that do not pollute the fluid and can quickly and flexibly control the pressure, flow and even shape as desired.

[0004] At the same time, people are used to wipe the anus with paper after defecation, which is not easy to wipe clean. In recent years, some people use the automatic device in the flush toilet to flush. A human water bag flusher is available on the market, which relies on the hand to squeeze the water bag hard, forcing the water in the water bag to flush the anus through the curved pipe at the end of the water bag.

[0005] The above prior art has the following deficiencies: 1) Because the buttocks on the left and right sides of the anus are lower than the anus after the human body squats, and the flush toilet does not rub the anus with water but only relies on high-pressure water to flush, so the sewage splashes too much on the buttocks; the sewage that falls back after flushing with the manual water bag flusher will also spread downward along the left and right buttocks; 2) The manual water bag flusher cannot rub the anus with water at the same time, and it is difficult to flush it clean because the water pressure is not enough when squeezed by hand; 3) If the anus is not hygienic for a long time, it is easy to develop hemorrhoids, and many people's buttocks on both sides of the anus are also infected because of dirt and wetness; if too much paper is used to wipe dry, it cannot be thrown into the toilet to avoid clogging and can only be thrown into the trash can, which will pollute the space. Summary of the invention

[0006] To achieve the above objectives, one of the objectives of the present invention is to provide a new technical solution: to eliminate the valve seat and valve core structure to avoid contamination caused by wear between them. At the same time, to eliminate the sealing parts such as packing to prevent external leakage, so that the switch is more flexible and the pressure and flow can be quickly and flexibly controlled as desired.

[0007] The technical solution of the present invention to solve the above technical problems is as follows:

[0008] Main body, double-layer pipe, horizontal gate, pipe groove, spring piece;

[0009] The interior of the main body is hollow and communicates with the outside through an inlet end and an outlet end. The inlet end and the outlet end are connected through the double-layer tube. The spring is fixed to the lower end of the interior of the main body, and the lower end of the tube groove is fixed to the upper end face of the spring. The double-layer tube is nested in the tube groove, and a notch is provided on the upper end face of the tube groove. The horizontal gate is fixed on the inner wall of the main body and inserted into the interior of the tube groove through the notch, while squeezing the double-layer tube and blocking the communication between the inlet end and the outlet end. The other end of the upper end face of the tube groove is also connected to one end of a push rod, which can drive the tube groove to press down the spring to produce elastic deformation; the other end of the push rod is pushed out of the main body and is closed and connected to the main body through a closing cover.

[0010] The beneficial effects of the present invention are: the horizontal gate is inserted into the interior of the pipe groove, squeezing the double-layer pipe and blocking the connection between the inlet and outlet ends, and the water flow in the double-layer pipe is cut off and does not flow under normal circumstances; the top rod is fixed on the pipe groove, and under the action of the spring sheet, the top rod can drive the pipe groove to be pressed down, and the upper end of the top rod is connected to a closed cover; when in use, by pressing the closed cover, the top rod is pressed down along the direction of the spring sheet, so that one end of the pipe groove moves downward, at this time, the squeezing between the double-layer pipe and the horizontal gate becomes smaller or even disappears, and the water flow can flow through the squeezing point. The valve is realized by eliminating the valve seat and valve core structure, avoiding internal structure wear, making the switch more flexible, and the pressure and flow can be quickly and flexibly controlled as desired.

[0011] On the basis of the above technical solution, the present invention can also be improved as follows:

[0012] The double-layer tube comprises an outer hard tube and an inner soft tube, the outer hard tube is made of polytetrafluoroethylene, and the inner soft tube is made of silicone.

[0013] The beneficial effect of adopting the above further scheme is that the outer hard tube and the inner soft tube of the double-layer tube are both tough, the outer hard tube is strong and can withstand the extrusion of the horizontal gate many times, and the inner soft tube is softer and easier to be squeezed than the outer hard tube. Under the action of the horizontal gate, the space inside the double-layer tube becomes smaller, leaving only a gap; the inner soft tube is squeezed under the action of water flow and pressure, and its own material is diverted to the gap, filling the gap, thereby achieving closure inside the tube.

[0014] Furthermore, the spring sheet is a U-shaped spring sheet.

[0015] The beneficial effects of adopting the above further solution are: the U-shaped spring piece has better elastic toughness and the force on the bottom of the lower end is more uniform.

[0016] Furthermore, the open end of the U-shaped spring sheet is located at the lower end of the tube groove.

[0017] The beneficial effect of adopting the above further solution is that the upper ends of the open end of the U-shaped spring sheet are respectively a pipe groove and a top rod, and under the action of the top rod, the U-shaped spring sheet is elastically deformed, thereby achieving the passage of water.

[0018] Furthermore, the sealing cover is a semi-arc structure made of elastic material, and the outer side wall of the sealing cover is provided with a circle of clamping grooves, and the clamping grooves are clamped and closed to the outer wall of the main body.

[0019] The beneficial effect of adopting the above further solution is that the sealing cover is made of elastic material to ensure reset before and after pressing, and the sealing cover seals the outer wall of the main body to ensure that the entire press-closed valve is closed inside to prevent debris from entering and affecting the use of the device.

[0020] Furthermore, the horizontal gate is a long strip with a cross section that is wide at the top and narrow at the bottom. It passes through the notch and is fixed to the inner wall of the main body, and the narrow part of its lower end abuts against the double-layer tube.

[0021] The beneficial effect of adopting the above further scheme is that the horizontal gate is a wedge-shaped structure that is wide at the top and narrow at the bottom, and the long ends on both sides are respectively fixed to the inner wall of the main body, and the narrow end can better squeeze the double-layer tube to achieve sealing inside the tube.

[0022] The second purpose of the present invention is to provide a post-defecation anal cleaner, comprising: a double-layer tube straight-through push-to-close valve without a valve seat, and also comprising an elastic telescopic water pipe, a lifting ball and an elastic rope, the elastic telescopic water pipe is connected to the inlet end of the main body, one end of the elastic rope is fixedly connected to the inner wall of the outlet end, the lifting ball is located at the outlet end of the main body, and the other end of the elastic rope is fixedly connected to the lifting ball.

[0023] The beneficial effect of adopting the above further scheme is that the lifting ball is located at the outlet end and is connected by an elastic rope. Its different positions at the end of the outlet and the terminal can directly affect the water outlet conditions - such as shape, strength, especially the mist shape, which is very comfortable for cleaning the sensitive anus. The position of the lifting ball is affected by the pressing of the closing valve and the water flow, and by the connection of the elastic rope. When the lifting ball is rushed closer to the outlet end or even partially exposed, the water pressure it receives naturally decreases. The elastic band pulls it back, and the water pressure accumulates to a certain level (the closing cover on the pressing closing valve can also be quickly adjusted), and it is rushed upward again. The whole process can ensure the controllability and comfort of flushing. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In order to make the purpose, technical solutions and advantages of the invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings, which is not intended to limit the scope of the present invention.

[0031] Example 1: Figure 1-2 As shown, an embodiment of a double-layer tube straight-through push-to-close valve without a valve seat disclosed in the present invention comprises:

[0032] Main body 1, double-layer pipe 2, horizontal gate 3, pipe groove 5, spring piece 7;

[0033] The main body 1 is hollow inside and communicates with the outside through the inlet end 11 and the outlet end 12. The inlet end 11 and the outlet end 12 are connected through the double-layer tube 2. The spring piece 7 is fixed to the lower end of the inside of the main body 1. The lower end of the tube groove 5 is fixed to the upper end face of the spring piece 7. The double-layer tube 2 is nested inside the tube groove 5. A notch 51 is provided on the upper end face of the tube groove 5. The horizontal gate 3 is fixed on the inner wall of the main body 1 and inserted into the inside of the tube groove 5 through the notch 51, while squeezing the double-layer tube 2 and blocking the communication between the inlet end 11 and the outlet end 12. The other end of the upper end face of the tube groove 5 is also connected to one end of the push rod 6, which can drive the tube groove 5 to press down the spring piece 7 to produce elastic deformation; the other end of the push rod 6 is pushed out of the main body 1 and is closed and connected to the main body 1 through the closing cover 4.

[0034] Specifically, the double-layer tube 2 connects the inlet end 11 and the outlet end 12 inside the main body 1, and the double-layer tube 2 is nested inside the tube groove 5. The lower end of the tube groove 5 is fixed on the spring sheet 7, and the upper end is connected to the push rod 6. The other end of the push rod 6 is closed and connected to the main body 1 through the closing cover 4; at the same time, a notch 51 is opened on the upper end face of the tube groove 5. Under normal circumstances, the horizontal gate 3 in the notch 51 squeezes the double-layer tube 2 and blocks the flow of the medium in the tube. The horizontal gate 3 is in the shape of a long strip and fixed at both ends of the inner walls. When in use, the closing cover 4 is pressed to drive the push rod 6 and the tube groove 5 to act on the spring sheet 7, and elastic deformation occurs to offset the squeezing of the spring sheet 7, thereby driving the double-layer tube to move away from the horizontal gate 3. The tube is no longer squeezed, the space gradually becomes larger, and the medium resumes circulation.

[0035] It should be understood that the double-layer tube 2 seals and connects the inlet end 11 and the outlet end 12, while the horizontal gate 3, the tube groove 5 and the top rod 6 are located outside the double-layer tube 2, which ensures the sealing of the internal water flow and the outside, avoids the wear of the components and the water flow in the device, and extends the service life of the product.

[0036] Optionally, the position of the horizontal gate 3 and the notch 51 in each batch of valves on the tube groove 5 is changeable, and it can be located at a position away from the push rod 6 or at a position close to the push rod 6. By changing the position, the size of the flow opening in the double-layer tube 2 at the horizontal gate 3 and the proportional adjustment of the downward movement of the push rod 6 can be optimized in the process of pressing the push rod 6 to drive the tube groove 5 and the spring piece 7 to move downward, thereby achieving the pressing strength in different situations to meet the fluid flow rate in the double-layer tube 2 with different requirements; when the horizontal gate 3 and the notch 51 are close to the push rod 6, the required pressing amplitude is very small, that is, the fluid flows out; when the horizontal gate 3 and the notch 51 are far from the push rod 6, the required pressing amplitude is larger, and the fluid can flow out.

[0037] Preferably, the tube groove is a U-shaped square groove with an open upper end surface or a hollow cylinder.

[0038] Preferably, when the closing cover 4 and the horizontal gate 3 are on the same cross-section, the required pressing amplitude is very small; when the closing cover 4 and the horizontal gate 3 are not on the same cross-section, the pressing force required by leveraging is even smaller.

[0039] Optionally, the device can also be applied to other fluid media.

[0040] Based on Example 1, Example 2: Figure 1 As shown, the double-layer tube 2 includes an outer hard tube 21 and an inner soft tube 22, the outer hard tube 21 is made of polytetrafluoroethylene, and the inner soft tube 22 is made of silicone.

[0041] Specifically, the outer hard tube 21 and the inner soft tube 22 have different toughness. The polytetrafluoroethylene material of the outer hard tube 21 is harder than the silicone material of the inner soft tube 22, and is more wear-resistant. It can withstand the extrusion of the horizontal gate 3 many times. The inner soft tube 22 is softer. When not in use, the double-layer tube 2 is squeezed. When the extrusion between the spring piece 7 and the horizontal gate 3 has not reached the absolute zero distance, that is, there is still a gap left, just like the increase in water flow in a narrow river channel, the silicone material of the inner soft tube 22 is pushed at the gap and actively closed under the action of Bernoulli's principle and atmospheric pressure, thereby achieving closure inside the tube.

[0042] It should be understood that the combination of silicone tubes with good chemical properties and non-toxicity and plastic king polytetrafluoroethylene tubes with good chemical properties and better physical properties, on the one hand, improves the service life of the device, and on the other hand, satisfies the function of sealing and partitioning in the tube under the action of the horizontal gate 3.

[0043] Based on Example 1, Example 3: Figure 1 As shown, the spring piece 7 is a U-shaped spring piece.

[0044] It should be understood that the U-shaped spring leaf has better elasticity and toughness, and the force on the bottom of the lower end is more uniform.

[0045] Based on Example 3, Example 4: Figure 1 As shown, the open end of the U-shaped spring sheet is located at the lower end of the tube groove 5.

[0046] Specifically, the upper ends of the open end of the U-shaped spring sheet are respectively a pipe groove 5 and a top rod 6. Under the action of the top rod 6, the elastic deformation of the U-shaped spring sheet is realized, and then the pipe groove 5 drives the double-layer pipe 2 to move toward the U-shaped spring sheet, the space inside the pipe becomes larger, and the water flow is then realized.

[0047] Based on Example 1, Example 5: Figure 1 As shown, the closing cover 4 is a semi-arc structure made of elastic material, and the outer side wall of the closing cover 4 is provided with a circle of clamping grooves, and the clamping grooves are clamped and closed to the outer wall of the main body 1.

[0048] It should be understood that the closing cover 4 is a semi-arc structure made of elastic material. On the one hand, the closing cover 4 can be pressed to drive the push rod 6 to move downward to achieve double-layer tube circulation. The closing cover is made of elastic material to ensure that it is reset before and after pressing. On the other hand, the closing cover closes the outer wall of the main body to ensure that the entire push-closed valve is closed to prevent debris from entering and affecting the use of the device.

[0049] Based on Example 1, Example 6: Figure 1-2 As shown, the horizontal gate 3 is a long strip with a cross section that is wide at the top and narrow at the bottom. It crosses the notch 51 and is fixed to the inner wall of the main body 1 , and the narrow part at the lower end thereof abuts against the double-layer tube 2 .

[0050] Specifically, the horizontal gate 3 is a wedge-shaped structure that is wide at the top and narrow at the bottom. The long ends on both sides are respectively fixed to the inner wall of the main body 1, and the narrow ends can better squeeze the double-layer tube to achieve sealing inside the tube.

[0051] Optionally, the push rod 6 and the horizontal gate 3 are in the same cross-section in the vertical direction, and the required pressing amplitude is small; when the push rod 6 and the horizontal gate 3 are not in the same cross-section in the vertical direction, the required pressing amplitude using the lever effect is large.

[0052] Based on Examples 1-6, Example 7: Figure 1-4 As shown, a post-defecation anal cleaner includes a double-layer tube straight-through push-to-close valve without a valve seat, and also includes an elastic telescopic water pipe 8, a lifting ball 9 and an elastic rope 10. The elastic telescopic water pipe 8 is connected to the inlet end 11 of the main body 1, and one end of the elastic rope 10 is fixedly connected to the inner wall of the outlet end 12. The lifting ball 9 is located at the outlet end 12 of the main body 1, and the other end of the elastic rope 10 is fixedly connected to the lifting ball 9.

[0053] Specifically, a post-defecation anal cleaner is provided, which includes a double-layer tube straight-through push-to-close valve without a valve seat. Under the action of the double-layer tube straight-through push-to-close valve without a valve seat, the function of flushing the anus can be achieved by pressing the closing cover, and the speed of the water flow can be adjusted by the pressing force.

[0054] At the same time, the elastic telescopic water pipe 8 is connected to the inlet end 11 of the main body 1, which can ensure the telescopicity of the connecting pipe of the post-defecation anal cleaner during use, and improve the convenience of the anal cleaner; the lifting ball 9 is located at the outlet end and is connected by the elastic rope 12. Its different positions at the end of the outlet and the end of the outlet can directly affect the water outlet condition; the position of the lifting ball is affected by the pressing of the closing valve and the water flow, and by the connection of the elastic rope. When the lifting ball is rushed closer to the outlet end or even partially exposed, the water pressure it receives naturally decreases, the elastic band pulls it back, and the water pressure accumulates to a certain level and it is rushed upward again. The whole process can ensure the controllability and comfort of flushing.

[0055] It should be understood that the diameter and hardness range of the double-layer tube 2 are closely related to the working pressure. Take the civil tap water pressure of 0.3Mpa as an example: even if the inner hose has a diameter of only 0.5mm and the flow resistance is as high as 50%, the water flowing out from the outlet end 12 within a few seconds is still more than 200 ml, which is completely enough to clean the anus when combined with water rubbing.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
