Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent sanitary ware and relates to a pulsating plunger pump flusher. Background Art

[0002] The flusher is an important component of an intelligent toilet, and the flushing function is one of the core functions of an intelligent toilet. How to flush more efficiently has always been a hot research direction for intelligent toilets.

[0003] Chinese Patent Invention 201810793909.5 discloses an intelligent toilet and a flushing method, including: a toilet main body, a foaming device and a flushing device; the toilet main body is provided with a toilet cavity and a water tank, the flushing device includes a water fitting and a flushing nozzle, the water fitting includes a water inlet and a water outlet, the water inlet is connected to the water tank through a first water pipe, the water outlet is connected to the flushing nozzle through a second water pipe, the foaming device is connected to the water fitting and the flushing nozzle through a third water pipe, wherein the third water pipe is communicated with the second water pipe, the water in the water tank enters the water fitting through the first water pipe, the water fitting passes the water into the foaming device and the flushing nozzle through the second water pipe and the third water pipe, the foaming device passes the foam into the flushing nozzle through the third water pipe and the second water pipe, and the flushing nozzle sprays the water and the foam into the toilet cavity in sequence. The disadvantage of this flushing structure is that the structure is too complex, the cost is high, and the installation and maintenance are both time-consuming and laborious.

[0004] Chinese Utility Model Patent CN203729388U discloses a swinging bubble water structure, including a main body, a jet plate, and a core main body. The main body is provided with a water channel, the jet plate is provided with jet holes, and the core main body is provided with a mixing cavity and air suction holes. The characteristics are that: the core main body is provided with an inclined impact surface, at least part of the jet holes are within the orthographic projection surface of the inclined impact surface, and the air suction holes of the core main body are connected to the atmosphere. The present utility model simplifies the internal structure of the generation of bubble water compared with the prior art, enhances the air suction effect, and can also swing the bubble water to expand the cleaning area. The disadvantages of this structure are that: the air suction holes are opened at the end of the water spraying port, which will inhale human excrement and the volatilized waste gas generated by the flushing water and then spray it onto the human body, causing hygiene and secondary infection problems; secondly, the vacuum air suction of the injector is realized by the pressure loss of the flowing water. Without a pressurizing pump, the jet effect achieved by the tap water pressure will be very limited.

[0005] In addition, pulse and water pressure are the key mechanisms for the pulsating flusher to play a cleaning role. The combined action of the two on the human body surface can produce an alternately circulating effect of pressurization and decompression. The pressurization stage is conducive to the water flow impacting the human body surface, and the decompression stage is conducive to the smooth outflow of dirt. Based on the above mechanism, the effect of the pulsating flusher is much better than that of an ordinary flusher. However, the technology of using a pulsating flusher on intelligent toilets is still blank at present.

[0006] Linear motor piston pumps are a commonly used type of piston pump, mostly with linear reciprocating motion. Chinese Patent Application CN106593807A discloses a shock-absorbing piston pump that uses a circular linear motor drive technology. It includes a specific ring-shaped piston that can rotate in the circumferential direction (clockwise / counterclockwise) under the drive of the surrounding coil. The water inlet and outlet chambers are integrated, thereby reducing system problems such as vibration generated when the left and right moving pistons of the current single-piston double-cylinder pump operate. Moreover, the piston is embedded in the arc-shaped drive coil, and the piston and the drive coil are supported by a copper-based oil-containing bearing. The water inlet and outlet chamber assembly is made into an integrated and centrally symmetric arrangement, and the pulsating high-pressure water outlet is mixed in the water outlet chamber or combined with a high-pressure air chamber, thereby reducing the pulsation of the final water outlet. The disadvantages are that the left and right reciprocating frequency cannot be too high and cannot reach the HZ level. Additionally, when the positive and negative drive signals in the coil alternate, there will be an eddy current phenomenon, resulting in coil heating. Summary of the Invention

[0007] In view of the deficiencies of the prior art, the present invention provides a pulsating piston pump flusher with high pressure, stable operation, low noise, and capable of realizing various flushing functions.

[0008] To solve the above technical problems, the object of the present invention is achieved through the following technical solutions:

[0009] A pulsating piston pump flusher includes two or more sets of closed circular ducts. The ducts intersect and communicate with each other, and a blocking point is formed at the communication point. A piston is arranged inside the ducts, and an electromagnetic coil is wound around the outside of the ducts. The electromagnetic coil drives the piston to move in the circumferential direction inside the ducts and successively pass through the blocking point. One or more sets of ducts are provided with a number of water outlets and a number of water inlets, and a spraying mechanism is arranged at the water outlet terminal.

[0010] Taking two sets of ducts as an example, the above ducts include a main duct in the horizontal direction and a secondary duct in the vertical direction. A main piston is arranged inside the main duct, and a main coil is wound around the outside of the main duct. The main coil drives the main piston to move in a circular motion inside the main duct. The main duct is provided with a water outlet and a water inlet. A secondary piston is arranged inside the secondary duct, and a secondary coil is arranged outside the secondary duct. The secondary coil drives the secondary piston to move in a circular motion inside the secondary duct. The secondary piston reaches the blocking point where the main duct and the secondary duct intersect first to form a plug, and water flows out at the water outlet in front of the main piston, and water is absorbed at the water inlet behind the main piston.

[0011] The diameters of the above main and secondary pistons are the same, and the structure of the secondary piston and its duct is the same as that of the main piston. During operation, when the main piston passes through the blocking point, it also plugs the secondary piston.

[0012] The surface of the above piston is coated with ceramics and installed in a duct lubricated by a copper-based oil-containing bearing to reduce friction, and the bearing is embedded in the duct.

[0013] The electromagnetic driving frequency of the above electromagnetic coil is adjustable in levels or continuously adjustable to adapt to different human sensations and achieve the most comfortable flushing effect.

[0014] An inlet joint is provided at the above inlet, and an inlet check valve is provided inside the inlet joint. An outlet joint is provided at the outlet, and an outlet check valve is provided inside the outlet joint. The check valve is preferably a check spring valve.

[0015] The above outlet joint can be integrally or separately processed and assembled, and a pressure stabilizing air chamber can be installed to smooth the peak value of the pulsation.

[0016] The above spraying mechanism is a cavitation nozzle, a water mist nozzle, and / or a jet ejector.

[0017] The working principle of the above jet ejector is as follows: The pressurized liquid is sprayed into a high-speed jet by the nozzle. Through the pulsating turbulent flow of the jet, a negative pressure is generated in the receiving chamber, and air is sucked in and mixed with the liquid jet. The turbulent diffusion of the liquid particles cuts the liquid into droplets, and the droplets crush the gas into tiny bubbles by impacting and colliding with gas molecules. The bubbles are dispersed in the liquid to form a stable bubbly flow. This micro-bubble water can quickly clean the dirty areas on the human body surface.

[0018] The above water mist nozzle can generate fine mist with a VMD (Volume Median Diameter) of 20 - 50 microns, so as to cover the space in the toilet like a "mist shield" to achieve the purpose of deodorization.

[0019] The above water outlet terminal can be a water outlet joint or a water outlet pipe connected to the water outlet joint. The above spraying mechanism can be directly connected to the water outlet joint or connected to the water outlet pipe.

[0020] The above spraying mechanism is provided with an inhalation mechanism for inhaling O₃ to generate disinfected water or inhaling O₂ to generate oxygen-rich water.

[0021] A protective sleeve is sleeved outside the above coil.

[0022] The above protective sleeve is an inlet pipe, the above water outlet terminal is a water outlet pipe, and a water temperature controller is provided at the end of the water outlet pipe.

[0023] A position sensor and a pressure and flow sensor are provided on the side of the above blocking point opposite to the movement direction of the plunger. The position sensor and the pressure and flow sensor are connected to the control device to control and adjust the movement of the plunger.

[0024] The above pulsating plunger pump flusher is installed on the skirt of the intelligent toilet.

[0025] The above water outlet terminal is a high-pressure micro-hole spray pipeline, the high-pressure micro-hole spray pipeline is hidden in the skirt, and nozzles capable of generating a mist shield and a foam shield are provided on the high-pressure micro-hole spray pipeline.

[0026] The pulsation frequency of the water output of the pump in the present invention is related to the energization frequency of the coil, and can also be set to be continuously adjustable or set in steps; the pump flow is positively correlated with the driving frequency of the electromagnetic coil. In theory, for one pulse, the plunger runs a certain distance, and under the action of the auxiliary plunger, control program, position sensor, and auxiliary coil, a plug is formed to generate a pulsating water output; the theoretical water output is the area of the plunger × the stroke of the plunger; the pressure of the pump water output is related to the structure. Since it is a positive displacement pump, the flow is independent of the pressure.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. The present invention adopts the circular linear motor drive technology. A specific circular plunger can rotate circumferentially in a conduit under the drive of the surrounding coil (lined with non-magnetic material), forming a linear motor drive pump with adjustable pulsation (frequency). The pulse frequency reaches the Hz level, and at the same time, it has the advantages of high pressure, stable operation, and low noise.

[0029] 2. The inlet and outlet joints of the present invention are evenly distributed on the conduit as required, and almost no system problems such as mechanical vibration generated when the moving plunger reciprocates left and right in the current single-plunger double-cylinder pump will occur.

[0030] 3. The circular conduit plunger pump of the present invention can be invisibly arranged using the long elliptical skirt of the toilet seat ring, which is not only more beautiful but also can further improve the cleaning effect.

[0031] 4. The water outlet terminal of the present invention can be equipped with various types and quantities of spraying mechanisms to achieve better and more diverse flushing effects. For example, using the assembled jet microbubble generator can generate jet bubble water with pulsation and cleaning effects, quickly cleaning the human body surface such as the anus after defecation, which is much better than the current direct flushing or rotary flushing effect. It can also further generate ozone water and oxygen-rich water to improve the cleaning effect. The spraying mechanism of the present invention can also generate a foam shield and a mist shield simultaneously to improve the sealing effect on the liquid and odor splashed during human excretion.

[0032] 5. The pulsed pressure water generated by the present invention can make the cavitation structure of the nozzle work better, achieving better effects.

[0033] 6. The present invention uses the water inlet pipe as a protective layer, which is wrapped outside the coil, so that the inlet water absorbs the heat generated when the pulsating alternating power supply alternates in the electromagnetic coil, thereby saving energy. At the same time, a water temperature controller can be set at the water outlet terminal to ensure the final water outlet temperature. Description of the Drawings

Detailed Embodiment

[0036] The present invention will be further described below with reference to the accompanying drawings by way of specific embodiments. Refer to Figure 1 :

[0037] A pulsating plunger pump flusher includes more than two sets of closed circular conduits. The conduits intersect and communicate with each other and form a blocking point at the communicating place. A plunger is arranged in the conduit, and an electromagnetic coil is wound around the outside of the conduit. The electromagnetic coil drives the plunger to move in the circumferential direction in the conduit and successively pass through the blocking point. One or more sets of conduits are provided with a plurality of water outlets and a plurality of water inlets, and a spraying mechanism is arranged at the water outlet terminal.

[0038] Refer to the attached Figure 1 , taking two sets of conduits as an example to illustrate the specific structure of the present invention. For the convenience of description, the two sets of conduits are divided into main and auxiliary. The above conduits include a horizontal main conduit 1 and a vertical auxiliary conduit 2. A main plunger 3 is arranged in the main conduit 1, and a main coil 4 is wound around the outside of the main conduit 1. The main coil 4 drives the main plunger 3 to move in a circular motion in the main conduit 1. The main conduit 1 is provided with a water outlet and a water inlet. An auxiliary plunger 5 is arranged in the auxiliary conduit 2, and an auxiliary coil 6 is arranged outside the auxiliary conduit 2. The auxiliary coil 6 drives the auxiliary plunger 5 to move in a circular motion in the auxiliary conduit 2. The auxiliary plunger 5 reaches the blocking point where the main conduit 1 and the auxiliary conduit 2 intersect first to form an embolism, and water flows out at the water outlet in front of the main plunger 3, and water is absorbed at the water inlet behind the main plunger 3. A water inlet joint 7 is arranged at the water inlet, and a water inlet check valve 8 is arranged in the water inlet joint 7. A water outlet joint 9 is arranged at the water outlet, and a water outlet check valve 10 is arranged in the water outlet joint 9. The check valve is preferably a one-way check spring valve. A position sensor 11 and a pressure and flow sensor 12 are arranged on one side of the blocking point opposite to the movement direction of the plunger. The position sensor 11 and the pressure and flow sensor 12 are connected to a control device to control and adjust the movement of the plunger.

[0039] The working process of the present invention is as follows: A periodic power supply is applied to the electromagnetic coil, and the main coil 4 drives the main plunger 3 surrounded by the main conduit 1 to perform a circular motion within the main conduit 1. When approaching the blocking point, the auxiliary plunger 5 reaches the blocking point first to form an embolism, blocking the liquid in the main flow channel and squeezing the water in front of the main plunger 3 into the water outlet joint 9 (equivalent to the water outlet chamber), resulting in a high-pressure water outlet once. If the water outlet joint 9 is equipped with a spraying mechanism such as a fine water mist nozzle, a spray is generated once, and a certain vacuum is formed behind the main plunger 3, sucking in water from the water inlet joint 7 (equivalent to the water inlet chamber). At the same time, the main plunger 3 and the auxiliary plunger 5 continue to move downward (circular motion). Under the joint control of the control device and the sensor, the phase of the auxiliary plunger 5 passes the blocking point slightly earlier and continues to repeat the formation of the embolism. Therefore, the main plunger 3 also repeatedly generates the process of squeezing out water / sucking in water again and again.

[0040] The above-mentioned spraying mechanism is a cavitation nozzle, a water mist nozzle, and / or a jet injector. The following examples illustrate the setting method of the spraying mechanism of the present invention:

[0041] The above-mentioned water outlet joint 9 is connected to a jet microbubble generator to generate jet bubble water with pulsation and cleaning effects, especially a mixed bubble liquid mixed with pure oxygen or ozone, which can quickly clean the human body surface such as the anus after defecation.

[0042] The above-mentioned water outlet joint 9 is connected to a high-pressure micro-hole spray pipeline, and the high-pressure micro-hole spray pipeline is hidden inside the skirt of the intelligent toilet. The high-pressure micro-hole spray pipeline uses a gem nozzle with a diameter of 0.15 mm, which can generate a suspended mist with a VMD of 20 - 50 microns to cover above the foam, so as to improve the sealing effect on the liquid and odor splashed during human excretion. And when flushing, a "continuous mist cover" is formed inside the entire toilet cavity to reduce the pollution of the air by the germs transpiring with the air during flushing.

[0043] A protective sleeve 13 is provided outside the above-mentioned coil. Preferably, the protective sleeve 13 is a water inlet pipe, and the water outlet terminal is a water outlet pipe. A water temperature controller is provided at the end of the water outlet pipe. Ensure that the final water outlet reaches a comfortable temperature for the human body.

[0044] The above-mentioned embodiments are only the preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
