Description

Technical Field

[0001] The present invention relates to the technical field of liquid flow switch control, and more specifically, to a hose with liquid flow switch control and a preparation method thereof. Background Art

[0002] Hoses are important components in modern industry. Hoses are mainly used as wire and cable protection tubes for wires, cables, and automation instrument signals, as well as civilian hoses. For example, the silicone hoses commonly used in recent years are widely loved by people for their good softness, simplified preparation process, good flexibility, anti-twisting, bending, and ability to withstand heavy loads, acid resistance, lubricating oil, coolant and other properties. In addition, the surface is glossy and friction-resistant, and it can withstand the heavy pressure of footsteps without breaking or deforming, and it can also recover quickly without any damage to itself.

[0003] The hose has good performance of conducting liquid flow, but in many occasions, it is necessary to control the opening and closing of the conducting liquid flow in the hose. At present, many places use a ball valve designed in the hose to control the opening and closing of the conducting liquid flow in the hose. The ball valve in the hose is very inconvenient to use due to reasons such as large size, complex manufacturing process, and inconvenient cleaning. In order to simplify the preparation process of the hose with liquid flow switch control, a hose valve with two or more flexible valve discs facing each other and extending obliquely upward on the inner wall of the pipeline has appeared on the market, such as disclosed in Chinese patent application Nos. 201420719627.8, 201520804442.1 and 201610322332.0.

[0004] However, the flexible valve flap on the inner wall of the hose can only be reset by its own elasticity to achieve closing control of the flow of liquid above the valve. After repeated use, the flexible valve flap itself weakens in elasticity and the influence of the opening between the flexible valve flaps, which will cause the hose to leak at the hose valve. Secondly, since the flexible valve flap extends upward, the flow of liquid will be deposited in the gap between the flexible valve flap and the inner wall of the hose, making it impossible to completely drain the liquid in the hose when the hose valve is opened, resulting in liquid residue. On the other hand, it also increases the difficulty of cleaning the hose, which is easy to dirty the user's hands and is not conducive to the user experience.

[0005] Therefore, in order to improve the comfort of using the hose to control the on and off of the fluid flow and avoid leakage or difficulty in cleaning when the fluid in the hose is conducted, it is an urgent problem to be solved in this field to provide a hose with a fluid flow switch control that can prevent leakage.

[0016] Optionally, the hose with liquid flow switch control also includes: a limiter, which is arranged on the inner wall of the tube body and located between the liquid inlet of the tube body and the liquid flow switch controller, and the limiter is two support rods arranged opposite to each other on the inner wall of the tube body, and the sum of the lengths of the two support rods along the direction perpendicular to the liquid flow is less than the diameter of the tube cavity and greater than or equal to one tenth of the diameter of the tube cavity.

[0020] Optionally, the hose with liquid flow switch control is prepared by integral molding.

[0021] On the other hand, the present invention also provides a method for preparing a hose with a flow switch control, comprising:

[0022] A hose mold is prepared according to the structure of the hose to be prepared, wherein the structure of the hose includes: a hose body, a liquid flow switch controller and a leak-proof cover; wherein,

[0023] The tube body is an elastic tube body, and a tube cavity for liquid flow is arranged in the tube body; one end of the tube body for the liquid to flow out is the tube body outlet;

[0024] The liquid flow switch controller is a control plate arranged on the inner wall of the lumen and perpendicular to the extension direction of the lumen, and the liquid flow switch controller is used to block the liquid flowing in the lumen from continuing to flow;

[0025] The leak-proof cover is a T-shaped cover covering the outlet of the tube body, comprising: a cover cap and a cover plug, wherein the diameter of the cover cap in a direction perpendicular to the extension direction of the tube cavity is greater than or equal to the diameter of the tube cavity, and the diameter of the cover plug is equal to the diameter of the tube cavity;

[0030] Compared with the prior art, the hose with liquid flow switch control and the preparation method thereof of the present invention achieve the following beneficial effects:

[0031] (1) The hose with liquid flow switch control described in the present invention supports the control plate through the leak-proof cover to block the liquid in the hose from leaking from the liquid flow switch controller, thereby realizing the closing function of the liquid in the hose through the liquid flow switch controller, and the control plate also has a secondary leak-proof effect through the leak-proof cover; when the support of the control plate by the leak-proof cover is removed, the liquid in the hose can break through the cutting line of the control plate under the action of its own pressure or gravity to form a conductive opening channel, thereby realizing the opening function of the liquid in the hose through the liquid flow switch controller.

[0032] (2) When in use, the hose with a liquid flow switch control described in the present invention prevents leakage of the hose by fastening the leak-proof cover on the hose, and fastens the leak-proof cover to the discharge end of the discharge pipe by the cover plug, thereby avoiding leakage caused by unstable fastening of the leak-proof cover, and further improving the leak-proof function of the hose.

[0033] (3) In the hose with liquid flow switch control described in the present invention, the control plate does not extend toward the liquid inlet of the hose. Compared with the prior art, this avoids the problem of liquid in the cavity remaining between the flexible valve disc and the cavity wall of the hose, thereby greatly reducing the difficulty of cleaning the hose.

[0034] Of course, any product implementing the present invention does not necessarily need to achieve all of the technical effects described above at the same time.

[0054] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention unless otherwise specifically stated.

[0055] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0056] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0057] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0058] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0059] Example

[0060] like Figure 1As shown, it is a schematic diagram of the structure of a hose with a herringbone valve in the prior art, wherein a lumen 102 is provided in the hose 101, and the lumen 102 is a channel for liquid to flow through the hose, and two or more flexible valve flaps 103 facing each other and extending obliquely upward are provided on the inner wall of the hose 101, and each flexible valve flap 103 is tightly connected and blocks the lumen, and a fold 104 is formed at the bottom of each flexible valve flap 103 by slotting, and when the pipeline is pressed, the flexible valve flap 103 can bend along the fold 104 and conduct the lumen.

[0061] The flexible valve flap on the inner wall of the hose in the prior art can only be reset by its own elasticity to achieve closing control of the liquid above the valve. After repeated use, the flexible valve flap itself weakens in elasticity and the influence of the opening between the flexible valve flaps, which will cause the hose to leak at the hose valve. Secondly, since the flexible valve flap extends upward, the liquid will be deposited in the gap between the flexible valve flap and the inner wall of the hose, making it impossible to completely drain the liquid in the hose when the hose valve is opened, resulting in liquid residue. On the other hand, it also increases the difficulty of cleaning the hose, which is easy to dirty the user's hands, which is not conducive to the user experience.

[0062] like Figure 2 As shown, it is a structural schematic diagram of a hose with a round ball discharge valve in the prior art. A tube cavity 202 is provided in the hose 201, and the tube cavity 202 is a channel for liquid to flow through the hose. A ball arc cavity 203 is provided on the inner wall of the hose 201, and a ball valve 204 is placed in the ball arc cavity 203. By pressing the outer wall of the ball arc cavity 203 of the hose, a liquid channel is squeezed out between the ball valve 204 and the ball arc cavity 203 so that the liquid can pass through the ball valve. After the pressing force on the outer wall of the ball arc cavity 203 of the hose is removed, the elasticity of the hose and the ball valve themselves is restored to the original state, blocking the liquid from passing through the valve, thereby realizing the control of the opening and closing of the liquid in the hose. However, this ball valve control method is complicated to operate, and requires the user to spend a large amount of pressing force, and the function of controlling the opening and closing of the discharge is unstable, which will cause the hose to leak.

[0063] In order to solve the above-mentioned problem of hose flow control, this embodiment provides a hose with a flow switch control, such as Figure 3 , which is a cross-sectional schematic diagram of a hose with a liquid flow switch control in this embodiment. The hose with a liquid flow switch control in this embodiment includes: a tube body 301, a liquid flow switch controller 302 and a leak-proof cover 303. The tube body 301 is an elastic tube body, such as a tube body made of silicone material, and a tube cavity 311 for liquid flow is provided in the tube body 301; one end of the tube body 301 for liquid to flow out is a tube body outlet 312.

[0064] The liquid flow switch controller 302 is a control piece arranged on the inner wall of the lumen 311 and perpendicular to the extension direction of the lumen 311 (direction A in the figure). The control piece can be a cut piece that cuts off the lumen and is prepared by integrally molding with the tube body. Optionally, the thickness of the cut piece can be greater than 0.1 mm and less than or equal to 50 mm. If the thickness of the cut piece is too small, it will increase the difficulty of the preparation process. If the thickness of the cut piece is too large, it will not be easy to deform under the action of pressure, which is not conducive to the opening of the liquid flow switch controller, and the liquid in the lumen cannot pass through the cut piece smoothly, and it cannot play a good control role. A cutting line 321 greater than or equal to one is arranged on the liquid flow switch controller 302; the liquid flowing in the lumen 311 is blocked from continuing to flow by the liquid flow switch controller 302.

[0065] In some optional embodiments, the cutting line 321 is located at the center of the liquid flow switch controller 302, and the length of the cutting line 302 is greater than zero and less than or equal to two-thirds of the diameter of the lumen. Optionally, the length of the cutting line 302 can be between 0.5 mm and 5 mm. Since the cutting line position can be opened to form a drainage channel of the hose, when its length is small, the drainage rate is slow, and when its length is large, it will cause a fast drainage rate, and the discharged liquid is easy to get on the user, which does not improve the user experience.

[0066] In some optional embodiments, different from the above embodiments, the distance between the liquid switch controller 302 and the tube body outlet 312 is between 4 mm and 100 mm. If the distance between the liquid switch controller 302 and the tube body outlet 312 is too far, it is not conducive to the flow of liquid in the tube cavity, and it is not conducive to the matching installation of the leak-proof cover 303 and the tube cavity 311. If the distance between the liquid switch controller 302 and the tube body outlet 312 is too close, it is not conducive to manufacturing, and it is not conducive to ensuring the seamless matching of the leak-proof cover 303 and the tube cavity 311, which may cause leakage even if the leak-proof cover is covered.

[0067] The leak-proof cover 303 is a T-shaped cover body covering the tube body outlet 312, including: a cap 331 and a plug 332. The diameter of the cap 331 in the direction perpendicular to the extension of the tube cavity is greater than or equal to the diameter of the tube cavity, and the diameter of the plug 332 is equal to the diameter of the tube cavity 311. The diameter of the plug 332 is equal to the diameter of the tube cavity 311 to ensure that the plug is tightly plugged in the tube cavity, and the diameter of the cap 331 is greater than or equal to the diameter of the tube cavity to ensure that the tube cavity is further tightly covered to avoid leakage of liquid in the tube cavity.

[0068] The liquid flow switch controller 302 is located between the leak-proof cover 303 and the liquid flow, and one end of the plug 332 is connected to the cap 331. When the other end of the plug 332 is in contact with the liquid flow switch controller 302, under the support of the plug 332, the liquid flow switch controller 302 closes the channel for liquid flow at the cutting line position, and there is no gap on the liquid flow switch controller 302; when the plug 332 is not in contact with the liquid flow switch controller 302 (such as removing the leak-proof cover 303 from the lumen 311), under the action of pressure parallel to the flow direction of the liquid in the lumen (such as pressing the outer wall of the tube body corresponding to the cutting line by hand) or under the action of the gravity of the liquid in the lumen itself, the control pieces on both sides of the cutting line 321 are split open, so that the liquid flow switch controller 302 forms a channel for liquid flow at the cutting line 321.

[0069] In some optional embodiments, such as Figure 4 As shown, Figure 3 A structural diagram of a liquid flow switch controller is shown in FIG. 1 . Different from the above-mentioned embodiment, the distance between the two ends of the cutting line 321 (here, a cutting line is used as an example) and the inner wall of the tube body 301 cavity is greater than or equal to 0 and less than or equal to nine-tenths of the diameter of the tube cavity 311. The outer side of the liquid flow switch controller 302 is integrally formed with the inner wall of the tube body 301 cavity, and no liquid leakage will occur between them. The liquid flow is controlled by opening and closing the cutting line to control the liquid flow or blocking at the position of the liquid flow switch controller. In addition, the liquid flow switch controller 302 of the present invention does not have a protrusion in the direction of liquid inlet into the tube cavity, so there will be no liquid residue at the position of the liquid flow switch controller, and the liquid in the tube cavity can be more thoroughly removed when the channel is opened.

[0070] like Figure 5 , which is a schematic diagram of the structure of the opening of the discharge channel in a liquid flow switch controller of a hose with a liquid flow switch control provided in an embodiment of the present invention, and is a schematic diagram of the structure when the discharge channel at the cutting line on the liquid flow switch controller is opened. The leak-proof cover 303 supported on the liquid flow switch controller is removed from the tube cavity 311, and under the action of the liquid's own gravity or the pressure outside the tube body, the control sheets on both sides of the cutting line 321 are split open to form channels 322 for liquid to flow through.

[0071] In some optional embodiments, such as Figure 6 As shown, Figure 3 Another structural schematic diagram of the liquid flow switch controller. Different from the above embodiment, the cutting line 321 on the liquid flow switch controller 302 can be greater than one, and the cutting lines intersect at one point. The leak-proof cover supported on the liquid flow switch controller is removed from the tube cavity. Under the action of the liquid's own gravity or the pressure on the outside of the tube body, the control sheets on both sides of the cutting line 321 are split open to form a channel.

[0072] In some optional embodiments, such as Figure 7 , which is a schematic diagram of the structure of a hose with a liquid flow switch control provided in an embodiment of the present invention. Different from the above-mentioned embodiment, the hose with a liquid flow switch control further includes: a connecting rod 333, which is a flexible rod (the connecting rod 333 can be a bendable rod made of the same material as the hose), one end of the connecting rod 333 is connected to the leakproof cover 303, and the other end of the connecting rod 333 is connected to the outer wall of the tube body 301 near the tube body outlet 312. The connecting rod is convenient for connecting the tube body and the leakproof cover to prevent the leakproof cover from falling off or being lost, and can also ensure that it is very convenient to locate the liquid outlet end of the hose.

[0073] In some optional embodiments, such as Figure 8 As shown, it is a structural schematic diagram of another hose with liquid flow switch control provided in an embodiment of the present invention, the liquid flow switch controller 302 includes: a liquid storage surface 322, the liquid storage surface 322 is a side of the liquid flow switch controller 302 away from the cap 303; the liquid storage surface 322 is recessed in the direction of the leak-proof cover 303.

[0074] In some optional embodiments, such as Fig. 9, which is a schematic diagram of the structure of another hose with a liquid flow switch control provided in an embodiment of the present invention. Different from the above embodiment, the liquid flow switch controller 302 includes: a liquid storage surface 322 and a support surface 323. The liquid storage surface 322 is the side of the liquid flow switch controller 302 away from the leakproof cover 303; the support surface 323 is the side of the liquid flow switch controller 302 close to the leakproof cover 303; the liquid storage surface is concave toward the leakproof cover 303. Optionally, the thickness of the lowest concave part of the liquid flow switch controller 302 can be between 0.1mm and 3mm. The liquid flow switch controller 302 concave toward the leakproof cover can make it possible for the liquid flow switch controller to open toward the liquid outlet under the pressure of the liquid in the hose or the pressure outside the hose when the support effect of the leakproof cover on the liquid flow switch controller on the support surface is removed, so as to form a liquid discharge channel toward the liquid outlet of the hose at the cutting line position. When the leakproof cover is tightly plugged in the hose, the support effect of the leakproof cover on the liquid flow switch controller on the support surface makes the liquid flow switch controller close at the cutting line position, thereby closing the discharge channel of the liquid flow switch controller at the cutting line position, and because the leakproof cover is tightly plugged between the liquid flow switch controller and the liquid outlet of the hose, it can also play a secondary leakproof effect of preventing liquid leakage in the hose. In some optional embodiments, the hose and the leakproof cover between the liquid flow switch controller and the liquid outlet can be set to a structure in which the diameter gradually increases from the position of the liquid flow switch controller to the position of the liquid outlet, such as a cone. The hose and the leakproof cover between the liquid flow switch controller and the liquid outlet are set to a structure in which the upper part is small and the lower part is large. In addition, the elastic effect of the hose and the leakproof cover themselves can ensure that the leakproof cover is tightly plugged in the position between the position of the liquid flow switch controller and the liquid outlet, increasing its stability, but does not affect the convenience of pulling out the leakproof cover from the hose.

[0075] In some optional embodiments, such as Fig.10 , which is a schematic diagram of the structure of another hose with flow switch control provided in an embodiment of the present invention, is different from the above embodiment in that a thread 334 is provided on the outer wall of the cover plug, and the leak-proof cover 303 is covered on the outlet of the tube body by the thread 334 of the cover plug and the inner wall of the tube body. Fig.11As shown, it is a structural schematic diagram of another hose with liquid flow switch control provided in an embodiment of the present invention. The inner wall of the tube body between the liquid flow switch controller 302 and the tube body outlet 312 is also provided with threads, and the leak-proof cover is covered on the tube body outlet through the threads 334 of the cover plug and the threads of the inner wall of the tube body. Since the entire hose, including the leak-proof cover, is made of flexible materials and has certain flexibility and elasticity, the leak-proof cover is provided with threads, so that the leak-proof cover can be tightly plugged in the hose to prevent the leak-proof cover from falling out of the hose. When the liquid in the hose does not need to flow out, it can also play a secondary leak-proof effect of preventing the liquid in the hose from leaking. The threaded cooperation between the inner wall of the hose and the leak-proof cover makes the two fit more closely, which can further increase the leak-proof effect. On the other hand, when it is necessary to drain the liquid, the user can easily pull out the leak-proof cover from the hose, which is easy to operate.

[0076] In some optional embodiments, such as Fig.12 As shown, it is a schematic diagram of the cross-sectional structure of a hose with a liquid flow switch control. Different from the above-mentioned embodiment, the hose with a liquid flow switch control also includes: a limiter 313, which is arranged on the inner wall of the tube body 301 and is located between the liquid inlet 314 of the tube body 301 and the liquid flow switch controller 302. The limiter 313 can be two support rods (limit rods) arranged opposite to each other on the inner wall of the tube body 301, and the sum of the lengths of the two support rods in the direction perpendicular to the liquid flow direction (such as direction A in the figure) is less than the diameter of the tube cavity and greater than or equal to one tenth of the diameter of the tube cavity. When pressure is applied to the outer wall of the hose to squeeze the hose, the support rods that should not be in contact with each other, i.e., the limiter 313, are squeezed to a position where they are in contact with each other, and the contact ends of the two support each other, so that the hose cannot be squeezed forward any further, causing the liquid flow channel opened at the cutting line position on the liquid flow switch controller to only open to the limit position, which ensures a good liquid flow effect in the hose without causing the liquid to flow too quickly in the hose, thereby preventing the problem of liquid getting on the user.

[0077] In some optional embodiments, such as Fig.12 and 13 As shown, Fig.13 : is another cross-sectional structural diagram of a hose with a liquid flow switch control, the hose with a liquid flow switch control comprises: a limiter, the limiter is arranged on the inner wall of the tube body 301, and is located between the liquid inlet 314 of the tube body and the liquid flow switch controller 302, the limiter is a limit rod 313 and a limit hole 315 arranged oppositely on the inner wall of the tube body. The diameter of the limit rod 313 is less than or equal to the diameter of the limit hole 315, and the sum of the lengths of the limit rod 313 and the limit hole 315 is less than or equal to nine tenths of the diameter of the tube cavity 311.

[0078] Alternatively, if Fig.14FIG. 1 is another optional cross-sectional structural diagram of a hose with a liquid flow switch control provided in this embodiment, which is similar to FIG. Fig.11 The difference is that the limiting rod 313 includes a fixing rod 316 connected to the inner wall of the tube body and an extension rod 317 connected to the fixing rod 316; the diameter of the extension rod 317 is less than or equal to the diameter of the limiting hole 315, and the diameter of the fixing rod 316 is greater than the diameter of the limiting hole 315; the sum of the lengths of the limiting rod 313 and the limiting hole 315 is less than or equal to nine-tenths of the diameter of the lumen 311.

[0079] In some optional embodiments, such as Fig.15 As shown, it is a structural schematic diagram of a hose with a liquid flow switch control, and the hose with a liquid flow switch control also includes: a positioner 318, which is located on the outer wall of the tube body 301 and is set at a position corresponding to the cutting line 321. The positioner 318 is used to help the user to locate the cutting line 321 position more conveniently. With a small pressure, the cutting line position of the liquid flow switch controller can be accurately squeezed to form a liquid channel. Optionally, the positioner 318 can be a marking point, or a groove body that is recessed into the inside of the tube body, or a groove body that first protrudes to form a protrusion platform and then recesses into the inside of the tube body on the protrusion platform. The recessed groove body can be a structure that matches the human finger, which is convenient for the user to use.

[0080] In some optional embodiments, such as Fig.16 The figure shows a schematic diagram of a hose with a flow switch control. Figure 3 The difference between the hose with liquid flow switch control shown in the figure is that the liquid flow switch controller 302 is arranged on the tube body outlet 312 of the tube body 301; the leak-proof cover 303 is a concave cap covering the outside of the tube body outlet 312, and the leak-proof cover 303 includes: a side cover 335 and a cap body 336, the side cover 335 is in contact with the tube body 301 at the tube body outlet 312, and the cap body 336 is in contact with the tube body outlet 312 to provide support for the liquid flow switch controller 302 so that the liquid flow switch controller 302 will not collapse. When the leak-proof cover 303 is removed, there is no support on the support surface of the liquid flow switch controller 302. Under the action of the gravity of the liquid in the hose itself or the pressure outside the hose, the cutting line position of the liquid flow switch controller 302 collapses, opening the liquid flow channel of the hose. Optionally, the leak-proof cover 303 here can also adopt the threaded matching form in the above embodiment to further prevent leakage, and on the other hand, a connecting rod connected to the hose body can also be provided on the leak-proof cover 303. Optionally, the liquid flow switch controller 302 can also be prepared into a concave surface structure, and a limit rod can also be provided in the hose, see the above description for details.

[0081] Optionally, the hose with liquid flow switch control in the above embodiment can be prepared by integral molding, for example, a silicone hose prepared by integral molding using silicone material.

[0082] In some optional embodiments, a method for preparing the above-mentioned hose with flow switch control is also provided, such as Fig.17 As shown, it is a schematic flow chart of a method for preparing the above-mentioned hose with flow switch control, which includes the following steps:

[0083] Step 1701, prepare a hose mold according to the structure of the hose to be prepared, wherein the structure of the hose includes: a hose body, a liquid flow switch controller and a leak-proof cover; wherein,

[0084] The tube body is an elastic tube body, and a tube cavity for liquid flow is arranged in the tube body; one end of the tube body for the liquid to flow out is the tube body outlet;

[0085] The liquid flow switch controller is a control plate arranged on the inner wall of the lumen and perpendicular to the extension direction of the lumen, and the liquid flow switch controller is used to block the liquid flowing in the lumen from continuing to flow;

[0086] The leak-proof cover is a T-shaped cover body covering the outlet of the tube body, comprising: a cover cap and a cover plug, wherein the diameter of the cover cap in the direction perpendicular to the extension direction of the tube lumen is greater than or equal to the diameter of the tube lumen, and the diameter of the cover plug is equal to the diameter of the tube lumen;

[0087] The liquid flow switch controller is located between the leak-proof cover and the liquid flow, and one end of the cover plug is connected to the cover cap. When the other end of the cover plug is in contact with the liquid flow switch controller, the liquid flow switch controller closes the channel for liquid flow at the cutting line position under the support of the cover plug; when the cover plug is not in contact with the liquid flow switch controller, the liquid flow switch controller forms a channel for the liquid to flow at the cutting line position under the action of pressure parallel to the flow direction of the liquid in the cavity.

[0088] Step 1702: Place the raw material for preparing the hose in the opening of the hose mold. If the hose with liquid flow switch control is a silicone hose, the raw material for preparing the hose is silicone material.

[0089] Step 1703: Pressing with a hose mold, optionally at a temperature of 100-300° C. and a pressure of 10 to 2000 tons for 1 to 20 minutes;

[0090] Step 1704, cool and remove the hose with liquid flow switch control from the hose mold.

[0091] Step 1705: Prepare a cutting line greater than or equal to one on the liquid flow switch controller. The cutting line greater than or equal to one can be punched out by stamping.

[0092] It can be seen from the above embodiments that the hose with liquid flow switch control and the preparation method thereof of the present invention achieve the following beneficial effects:

[0093] (1) The hose with liquid flow switch control described in the present invention supports the control plate through the leak-proof cover to block the liquid in the hose from leaking from the liquid flow switch controller, thereby realizing the closing function of the liquid in the hose through the liquid flow switch controller, and the control plate also has a secondary leak-proof effect through the leak-proof cover; when the support of the control plate by the leak-proof cover is removed, the liquid in the hose can break through the cutting line of the control plate under the action of its own pressure or gravity to form a conductive opening channel, thereby realizing the opening function of the liquid in the hose through the liquid flow switch controller.

[0094] (2) When in use, the hose with a liquid flow switch control described in the present invention prevents leakage of the hose by fastening the leak-proof cover on the hose, and fastens the leak-proof cover to the discharge end of the discharge pipe by the cover plug, thereby avoiding leakage caused by unstable fastening of the leak-proof cover, and further improving the leak-proof function of the hose.

[0095] (3) In the hose with liquid flow switch control described in the present invention, the control plate does not extend toward the liquid inlet of the hose. Compared with the prior art, this avoids the problem of liquid in the cavity remaining between the flexible valve disc and the cavity wall of the hose, thereby greatly reducing the difficulty of cleaning the hose.

[0096] Although some specific embodiments of the present invention have been described in detail by way of example, it will be appreciated by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present invention. It will be appreciated by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
