Description

Technical Field

[0001] The present application relates to the technical field of toilets, and in particular to a pressure and flow increasing system for toilets. Background Art

[0002] Many existing toilets were built many years ago, and the flushing standards are low, especially in public toilets, where the pipes are mostly DN15 and DN20, which can only provide low water pressure and low flow. The flow pressure of the previous pipes is far from meeting the flushing needs of the new water-saving sanitary ware. Due to the construction of the urban area, it is difficult to replace the pipes as a whole, but the replacement of the new water-saving sanitary ware has been carried out, and the water flow cannot meet the requirements when it is used, which has caused great trouble to the cleaners and the use environment. Utility Model Content

[0003] The purpose of this application is to provide a toilet pressure-boosting and flow-increasing system, which can achieve the effect of pressure-boosting and flow-increasing for toilets with low water pressure and low water flow to meet the flushing needs of users.

[0004] In order to solve the above technical problems, the present application provides a pressure-increasing and flow-increasing system for a toilet, comprising:

[0005] Water inlet pipe;

[0006] an auxiliary water tank, the auxiliary water tank having a water inlet and a water outlet, the water inlet being connected to a first position of the water inlet pipeline, the water outlet being connected to a second position of the water inlet pipeline, the first position being located upstream of the second position;

[0007] A booster pump, the water outlet end of the water inlet pipeline is connected to the pump inlet of the booster pump, and the pump outlet of the booster pump is used to be connected to the water-using sanitary ware in the bathroom.

[0008] In one embodiment, the auxiliary water tank is a closed water tank; the pressure and flow increasing system further includes an air inlet valve and an air outlet valve disposed on the closed water tank, and the air inlet valve and the air outlet valve are connected to the atmosphere.

[0009] In one embodiment, the closed water tank is buried under the floor of the bathroom.

[0010] In one embodiment, the air inlet valve and the air outlet valve are integrated into an integral structure.

[0011] In one embodiment, the auxiliary water tank includes a tank body with an opening at the top and a tank cover covering the opening; the pressure and flow increasing system also includes a control valve, and the control valve is used to control the water level in the auxiliary water tank not to exceed the opening.

[0012] In one embodiment, the control valve is a float valve.

[0013] In one embodiment, the auxiliary water tank is disposed above the floor of the toilet.

[0014] In one embodiment, the pressure and flow increasing system also includes a first one-way valve and a second one-way valve. The first one-way valve is provided in the passage between the water inlet pipe and the water inlet of the auxiliary water tank, and the second one-way valve is provided in the passage between the auxiliary water tank and the water inlet pipe.

[0015] In one embodiment, the pressure-boosting and flow-increasing system further includes an air-water mixing device, and the air-water mixing device is disposed between the pressure-boosting pump and the water-using sanitary appliance.

[0016] The boosting and flow-increasing system in the present application is equipped with an auxiliary water tank. When the water inlet pipeline does not need to provide water to the water-using sanitary ware, the water in the water inlet pipeline can flow to the auxiliary water tank for storage. When the water-using sanitary ware needs water, if the water flow in the water inlet pipeline is too small, the booster pump can simultaneously suck the water stored in the auxiliary water tank to suck water with a sufficient flow rate, and pump it to the water-using sanitary ware after boosting the pressure together with the water in the water inlet pipeline to meet the water demand. In this way, no matter how low the water pressure and water flow of the water inlet pipeline are, the booster pump can obtain the required amount of water and boost the pressure to meet the user's use needs, which is also conducive to extending the service life of the booster pump.

[0030] In order to enable those skilled in the art to better understand the technical solution of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] In the embodiments of the present application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0032] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the pressure and flow increase system for the bathroom in the first embodiment of the present application.

[0033] The pressure-increasing and flow-increasing system for the toilet in the embodiment of the present application is suitable for the toilet water supply system with low water pressure and low water flow. Low water pressure means that the water pressure is low, and low water flow means that the water flow is low. On the basis of the water supply system with low water pressure and low water flow, a pressure-increasing and flow-increasing transformation is performed. Specifically, the pressure-increasing and flow-increasing system includes a water inlet pipeline 100, an auxiliary water tank 200, and a booster pump 300.

[0034] The water inlet pipe 100 is used to connect to a water source with low water pressure and low water flow, and the water source can be any equipment or system that can provide water. For example, if the bathroom has an original water supply pipe, the water inlet end 100a of the water inlet pipe 100 can be connected to the original water supply pipe. Figure 1 As shown, the water inlet pipeline 100 can be connected to the original water supply pipeline through a pipe joint; alternatively, the water inlet pipeline 100 can also be a part of the original water supply pipeline, and the auxiliary water tank 200 can also be connected to the original water supply pipeline.

[0035] like Figure 1As shown, the auxiliary water tank 200 has a water inlet 200a and a water outlet 200b, the water inlet 200a is connected to the first position 100A of the water inlet pipe 100, and the water outlet 200b is connected to the second position 100B of the water inlet pipe 100, and the first position 100A is located upstream of the second position 100B, so that the water in the water inlet pipe 100 can enter the auxiliary water tank 200 from the water inlet 200a and be stored in the auxiliary water tank 200. When the water in the auxiliary water tank 200 is needed, the water in the auxiliary water tank 200 can enter the water inlet pipe 100 again from the water outlet 200b and merge with the water with low water pressure and low water flow in the water inlet pipe 100.

[0036] The pump outlet of the booster pump 300 in the booster flow system is used to communicate with the water-using sanitary ware 700 in the bathroom, and the pump inlet of the booster pump 300 is connected to the water outlet 100b of the water inlet pipeline 100. When the booster pump 300 is working, the water in the water inlet pipeline 100 can be pressurized. The principle of pressurization itself is the existing technology and will not be repeated here. The booster pump 300 can also draw water from the auxiliary water tank 200 at the same time, and the water from the water inlet pipeline 100 and the auxiliary water tank 200 is simultaneously pressurized and delivered to the downstream water-using sanitary ware 700 to meet the flushing requirements.

[0037] The bathroom is usually provided with water-using sanitary ware 700, such as a squat toilet, a toilet, a urinal, a wash basin, etc. Figure 1 Taking a squat toilet as an example, it is also equipped with a foot valve 800. After use, the user can step on the foot valve 800 to flush. Of course, there are many ways to control the flushing, and it can also be a manual press valve, an automatic sensing flush valve, etc. The embodiment of the present application does not make specific restrictions on the structural form of the flushing control valve. The water supply for flushing comes from the booster pump 300. The booster pump 300 can provide water for one water-using sanitary ware 700, or it can provide water for multiple water-using sanitary ware 700, and it can be set according to actual needs.

[0038] It can be seen that the boosting and flow-increasing system in the embodiment of the present application is equipped with an auxiliary water tank 200. When the water inlet pipeline 100 does not need to provide water to the water-using sanitary ware 700, the water in the water inlet pipeline 100 can flow to the auxiliary water tank 200 for storage. When the water-using sanitary ware 700 needs water, if the water flow rate of the water in the water inlet pipeline 100 is sufficient, the booster pump 300 directly sucks the water in the water inlet pipeline 100 for pressurization, and then pumps it to the water-using sanitary ware 700; if the water flow rate in the water inlet pipeline 100 is small, the booster pump 300 can simultaneously suck the water stored in the auxiliary water tank 200 to suck water with sufficient flow, and pump it to the water-using sanitary ware 700 after pressurization to meet the water demand. In this way, no matter how low the water pressure and water flow of the water inlet pipeline 100 are, the booster pump 300 can obtain the required amount of water and pressurize it to meet the user's use needs.

[0039] It should be emphasized that the pressure-increasing and flow-increasing system in this embodiment can improve the water shortage in the toilet, especially for the application scenario of extremely low water pressure and low water flow, and the improvement effect is obvious. As described in the background technology part, for toilets with a long service life (usually public toilets), the pipe specifications are DN15, DN20, etc., that is, the diameter of the pipe is 15 inches, 20 inches, the pipe is very narrow, the water pressure is even only 0.01MPa, and the water flow rate is only about 6L / min. This water supply situation cannot meet the flushing requirements for the new water-using sanitary ware 700.

[0040] It should be known that the water pressure of modern water supply pipelines that meet the flushing requirements can often reach 0.2MPa~0.4MPa, and the water flow rate can reach 280L / min~560L / min. It can be seen that the water supply with extreme low water pressure and low water flow and the current use requirements of the new water-using sanitary ware 700 differ by dozens of times in terms of water pressure and flow rate, which is a huge difference. If the boosting is only performed by the booster pump 300, since the water flow is far from enough, most of the boosting process of the booster pump 300 is an idling process, which is easy to wear the booster pump 300. In addition, the flushing of the water-using sanitary ware 700 is relatively frequent, so the booster pump 300 idles and is frequently started and stopped, and the service life of the booster pump 300 will be very short. In the embodiment of the present application, since the auxiliary water tank 200 is provided, sufficient water can be provided to the booster pump 300 when the water volume is insufficient. Therefore, the booster pump 300 is not easily damaged and its service life can be extended, which has practical significance for the modification of application scenarios with extremely low water pressure and low water flow. In addition, during use, the increase in water volume relies on the water stored in the auxiliary water tank 200, and will not affect the water consumption of other users in the surrounding area of ​​the water supply system.

[0041] In detail, Figure 1 In the embodiment, the auxiliary water tank 200 includes a box body 201 with an opening at the top and a box cover 202 covering the opening. The auxiliary water tank 200 of this structural form has a simple structure and low processing cost. At this time, the boosting and flow increasing system also includes a control valve, which is used to control the water level in the auxiliary water tank 200 not to exceed the opening of the box body 201. It can be seen that since the box body 201 is provided with a box cover 202, if the water in the water inlet pipeline 100 enters the box body 201, the water may flow out from the gap between the box cover 202 and the box body 201, so a control valve can be provided to control the water level of the water stored in the auxiliary water tank 200 not to exceed the opening, thereby avoiding water overflow.

[0042] As a specific example, the control valve can be a float valve, which includes a float 501 and a connecting rod 502. The float 501 floats in the auxiliary water tank 200. When the water level reaches a preset water level (the preset water level is lower than the opening), the float 501 rises to drive the connecting rod 502 to close the float valve, and the passage between the water inlet pipeline 100 and the auxiliary water tank 200 is cut off, and water no longer enters the auxiliary water tank 200. As long as the water level does not reach the preset water level, the float valve is in an open state. The float valve can automatically control the opening and closing of the valve according to the change of the water level, and the cost is low; of course, the control valve is not limited to a float valve, and can also be other valve structures, such as a solenoid valve.

[0043] In addition, the auxiliary water tank 200 in this embodiment can be set on the floor of the bathroom, for example, it can be supported on the ground or a workbench in the bathroom, or it can be hung on the wall or ceiling of the bathroom, etc. This embodiment does not make specific restrictions.

[0044] In addition, the boosting and flow increasing system in this embodiment also includes a first one-way valve 401 and a second one-way valve 402. The passage between the water inlet pipe 100 and the water inlet 200a of the auxiliary water tank 200 is provided with a first one-way valve 401, that is, there is a first one-way valve 401 between the first position A and the water inlet 200a, and the passage between the auxiliary water tank 200 and the water inlet pipe 100 is provided with a second one-way valve 402, that is, there is a second one-way valve 402 between the auxiliary water tank 200 and the second position B. The opening pressure of the first one-way valve 401 can be set to be relatively low, so that as long as there is a certain amount of water flow in the water inlet pipeline 100, the water can flow to the auxiliary water tank 200 for storage. For example, in the case of the extremely low water pressure and low water flow mentioned above, water can still flow to the auxiliary water tank 200, and the water inlet 200a of the auxiliary water tank 200 can be lower than the water inlet pipeline 100. In this way, even if the water pressure is extremely low, as long as there is water flow, it can still flow to the auxiliary water tank 200 under the action of gravity. It can be seen that the setting of the first one-way valve 401 here is not to introduce a certain pressure of water flow into the auxiliary water tank 200, but to use its one-way function to prevent the water in the auxiliary water tank 200 from returning to the water inlet pipeline 100 from the water inlet 200a.

[0045] The opening pressure of the second one-way valve 402 can be set to be relatively high, higher than the opening pressure of the first one-way valve 401, so that it can be ensured that the storage volume in the auxiliary water tank 200 can reach a certain amount before being pumped by the booster pump 300 to meet the water volume demand. In the height direction, the position of the water outlet 200b can be lower than the position of the water inlet 200a, the water outlet 200b can be set to a position close to the bottom of the auxiliary water tank 200, and the water inlet 200a can be set to a position close to the top of the auxiliary water tank 200.

[0046] like Figure 1As shown, the boosting and flow-increasing system in this embodiment also includes a gas-water mixing device 600, which is arranged between the pump outlet of the boosting pump 300 and the water-using sanitary ware 700. The gas-water mixing device 600 includes a self-priming device 601, a regulating valve 602, and a mixing tank 603. The self-priming device 601 can automatically inhale gas when water flows through it by using the negative pressure principle. The self-priming device 601, for example, includes a venturi tube. The pipeline connected to the pump outlet of the boosting pump 300 is divided into two branches in the gas-water mixing device 600. One branch is provided with a self-priming device 601 and connected to the mixing tank 603. The gas-water mixed flow mixed with gas in the mixing tank 603 and the water flow of the other branch merge again and flow to the water-using sanitary ware 700, thereby improving the flushing effect. Of course, it is also possible not to set the gas-water mixing device 600.

[0047] Please continue to refer to Figure 2 , Figure 2 This is a schematic diagram of the pressurization and flow-increasing system for the bathroom in the second embodiment of the present application.

[0048] The second embodiment is basically similar to the first embodiment, except that the auxiliary water tank 200 in the second embodiment is not a separate structure of the box body 201 and the box cover 202. The auxiliary water tank 200 in the second embodiment is a closed water tank, that is, the auxiliary water tank 200 is an integrated structure. At this time, the water flowing into the auxiliary water tank 200 from the water inlet pipeline 100 will not overflow the closed water tank, and the auxiliary water tank 200 does not need to be provided with a control valve for controlling the water level, but the boosting and flow increasing system at this time also includes an air inlet valve 901 and an air outlet valve 902 provided in the closed water tank, and both the air inlet valve 901 and the air outlet valve 902 can be connected to the atmosphere.

[0049] When the auxiliary water tank 200 is a closed water tank, the interior of the closed water tank needs to be connected to the atmosphere through the air inlet valve 901 and the air outlet valve 902. In this way, when the booster pump 300 needs to pump water in the auxiliary water tank 200, the air inlet valve 901 can be opened, which is conducive to the pumping of the booster pump 300, and the water can smoothly enter the booster pump 300 under the action of the pressure difference; after the booster pump 300 stops pumping the auxiliary water tank 200, the air inlet valve 901 is closed, and the air outlet valve 902 needs to be opened, so that the water in the water inlet pipeline 100 can enter the auxiliary water tank 200 and squeeze the internal gas from the air outlet valve 902, that is, to ensure that the water smoothly enters the auxiliary water tank 200 for storage. Using a closed water tank as the auxiliary water tank 200 can reduce the impact of the external environment on the auxiliary water tank 200, and prevent impurities, foreign matter, etc. from entering the auxiliary water tank 200 and interfering with the operation of the auxiliary water tank 200. Moreover, the closed water tank can be filled with water, and the utilization rate of the auxiliary water tank 200 is relatively high.

[0050] In addition, when the auxiliary water tank 200 is a closed water tank, the closed water tank can be buried under the ground, which can be under the ground of the bathroom or under the ground outside the bathroom. As mentioned above, the boosting and flow increasing system in the embodiment of the present application is mainly for the application scenario of the bathroom with low water pressure and low water flow. The bathroom in this scenario is often relatively narrow. If the auxiliary water tank 200 is set on the ground, there may be a situation of insufficient space. If it is set at a location outside the bathroom, on the one hand, it is not conducive to the neat appearance, and on the other hand, there is also the problem of occupying space. If the auxiliary water tank 200 is set as a closed water tank, it can be buried under the ground, so that there is no need to occupy the ground space of the bathroom, which can not only realize the transformation, but also save space. Moreover, when it is set under the ground, the height of the auxiliary water tank 200 is relatively low, which is more conducive to the water in the water inlet pipeline 200 with low water pressure and low water flow flowing to the auxiliary water tank 200 for storage.

[0051] The outer surface of the closed water tank in this embodiment can be provided with a corrosion-resistant coating, so that after the closed water tank is buried under the ground, the influence of the soil layer under the ground on the outer surface of the closed water tank can be reduced to prevent damage to the auxiliary water tank 200. It can be understood that the outer surface of the closed water tank can also be left untreated, for example, the material of the closed water tank itself has a corrosion-resistant property, or, when a pre-buried pit is dug under the ground, a cement layer or a waterproof layer can be laid on the bottom and surroundings of the pre-buried pit, so that the auxiliary water tank 200 is in a relatively clean and dry environment, which is convenient for subsequent operators to perform maintenance, replacement, etc. on the auxiliary water tank 200, and on the other hand, it is also beneficial for the auxiliary water tank 200 to be not damaged.

[0052] Please continue to refer to Figure 3 , Figure 3 This is a schematic diagram of the pressurization and flow-increasing system for the bathroom in the third embodiment of the present application.

[0053] The third embodiment is basically similar to the second embodiment, except that the auxiliary water tank 200 in the third embodiment is equipped with an air valve 900. The air valve 900 integrates the functions of air intake and air outlet, that is, the air intake valve 901 and the air outlet valve 902 are integrated into one valve body to form the air valve 900, which has a simpler structure.

[0054] The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
