Description

micro bubble generator

technical field

The invention relates to a micro-bubble generating device, in particular to a micro-bubble generating device using a non-self-priming motor pump.

Background technique

A conventional microbubble generator is disclosed in Korean Patent Publication No. 2003-0010685.

Fig. 1 is a structural diagram of a conventional microbubble generating device using a non-self-priming motor pump.

The micro-bubble generating device puts the water inlet nozzle 101 and the water outlet nozzle 118 into the water in the bathtub and then starts the motor pump 100 to circulate the washing water, and forms an air suction port 109 on the pump inlet side to suck in air while sucking the washing water, The washing water and air flowing into the motor pump 100 flow through the bucket 126 provided with an air vent 125 and are pressurized by the pressure plate provided at the outlet nozzle 118, and then forcefully hit the grid assembly to generate tiny bubble.

As shown in Figure 1, the existing micro-bubble generating device is equipped with a water inlet nozzle 101 on the water inlet hose 102 of the motor pump 100, and a filter screen for filtering foreign matter during suction is provided inside the water inlet nozzle 101, and passes through the pump outlet. The water bucket 126 that is provided with exhaust valve 125 is installed at the rear end of outlet pipe 115 .

When using the micro-bubble generating device of prior art structure, if the water level in the bathtub is lower than the position where the motor pump 100 is located, the water inlet hose 102 and the water inlet nozzle 101 are filled with air and the pump head 113 cannot suck. The washing water in the bathtub needs to be artificially injected into the pump head 113 by the water inlet nozzle 101.

Moreover, since there is no blocking device separately provided on the air suction port 109, even if the washing water is injected artificially, air will continuously flow into the air suction port 109, so it takes a long time to provide water pressure for the motor pump. .

As mentioned above, when the water pressure is supplied to the motor pump 100 to circulate the washing water, the washing water also flows through the bucket 126 provided with a separate air discharge valve 125, and generates micro air bubbles through the water outlet nozzle 118 to be discharged into the bathtub. . At this time, the water tub 126 is provided with an exhaust valve 125 on an upper portion of the water tub 126 in order to discharge the air not mixed with the washing water to the atmosphere.

Therefore, it occupies a large internal space of the micro-bubble generating device, so that the utilization of the space is greatly limited.

Moreover, when the micro-bubble generating device is used, foreign matter, dirt, skin cutin, etc. inside the bathtub will block the grid assembly arranged on the water outlet nozzle 118, so that the motor pump 100 will be overloaded, and the pressure of the water outlet pipeline 115 will increase. As a result, the water tub 126 is damaged, or the outlet hose 117 bursts and the washing water leaks into the inside of the micro-bubble generating device, which may even cause dangers such as a short circuit of the electric wire.

Moreover, in the process of using the micro-bubble generating device, when the grid assembly is blocked and needs to be replaced, because the nozzle body, the nozzle cover (nozzle cover), the grid assembly, and the pressure plate are mutually separate structures, so There are many inconveniences in replacing the grille assembly.

Detailed ways

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 and FIG. 3 are structural diagrams of the micro-bubble generating device provided by the present invention.

As shown in Figure 2 and Figure 3, the water inlet pipe 103 of the motor pump 100 of the present invention is connected with the water inlet hose 102, and the water inlet hose 102 is connected with the water inlet nozzle 101. A filter that filters out foreign matter when the wash water is sucked.

A check valve 119 is provided between the water inlet pipe 103 and the water inlet hose 102 of the motor pump 100 to prevent the washing water flowing into the water inlet pipe 103 , the main water inlet pipe 104 and the auxiliary water inlet pipe 105 from flowing to the outside. This is to assist the self-priming of the motor pump 100 when it is working. As shown in FIG. 2 , the main water inlet pipe 104 and the auxiliary water inlet pipe 105 are branched from the water inlet pipe 103 of the motor pump 100 , and the auxiliary water inlet pipe 105 is provided with a flow detection sensor 106 .

This is to distinguish whether the washing water flows into the water inlet pipe 103 or whether the water inlet nozzle 101 is exposed to the outside of the tub due to a user's mistake during use of the product and air flows into the water inlet nozzle 101 .

When the washing water flows into the water inlet nozzle 101, the pulse (Pulse) value of the flow detection sensor 106 will be significantly increased compared with when the air flows in because the viscosity of the washing water is greater than that of the air. The viscosity of the air is lower than that of the washing water and the pulse value of the flow detection sensor 106 is significantly lower than that when the washing water flows in. Here, a flow rate detection sensor 106 is provided in the auxiliary water inlet pipe 105, and the pulse difference is used to distinguish whether it is washing water or air flowing into the water inlet nozzle 101. When it is detected that air flows into the water inlet nozzle 101, the use of the micro-bubble generating device is stopped.

According to the configuration as described above, idling of the motor pump 100 is prevented, thereby preventing wear of the internal components of the motor pump 100 .

Moreover, the water inlet/outlet hoses 102, 117 and the water inlet/outlet pipes 103, 115 are connected by a coupling 119-1, so that when the product is stored after using the microbubble generating device, the tube and the product can be easily separated. main body.

As mentioned above, the sucked washing water enters the pump head 113 through the pump inlet 111, and the starting water pipe 114 connected with the pressure valve 130 is arranged between the pump inlet 111 and the pump head 113, and the air suction port 109 and the solenoid valve 110 In communication with each other, a temperature sensor 108 is provided on the temperature sensor seat 107 .

The pump outlet 112 side is connected with the multifunctional bucket 120, and the multifunctional bucket 120 has: a multifunctional bucket inlet 121 connected with the pump outlet 112; a multifunctional bucket upper hole 123 connected with the exhaust valve 125 at the top; The lower hole 124 of the multifunctional water bucket communicated with the pressure valve 130 ; and the outlet 122 of the multifunctional water bucket communicated with the outlet pipe 115 .

The water outlet pipe 115 is in communication with the multifunctional bucket outlet 122, and a pressure sensor 116 is arranged on one side of the piping of "T" shape between the water outlet pipe 115 and the water outlet nozzle 118, and the other side communicates with the water outlet hose 117.

When bathing, if the grid assembly 153 of the water outlet nozzle 118 is blocked, the pressure of the pipeline will rise, and the pressure sensor 116 will notify the user after detecting the pressure, and inform the replacement time of the grid assembly 153 .

The water outlet nozzle 118 communicates with the water outlet hose 117 .

When the micro-bubble generating device constituted as above is driven, if the motor pump 100 is started, the washing water in the bathtub starts to be sucked through the water inlet nozzle 101, and the sucked washing water flows through the water inlet hose 102, the water inlet nozzle, The pipe 103 flows into the pump head 113 through the main water inlet pipe 104 , the auxiliary water inlet pipe 105 and the pump inlet 111 . Here, the auxiliary water inlet pipe 105 is provided with a flow detection sensor 106 capable of detecting whether the washing water is normally sucked in or air is sucked in, and the reason why the flow detection sensor 106 is arranged on the side of the water inlet pipe 103 is because the water inlet pipe The pressure of 103 is lower than the pressure of the outlet pipe 115, so the probability of damage and error of the flow detection sensor 106 can be minimized.

As described above, when the wash water flows into the pump head 113, air flows in through the air inlet 109, and the solenoid valve 110 controls the opening/closing of the air inlet 109 to control the inflow of air.

When the motor pump 100 is driven initially, if air flows into the pump head 113, the motor pump 100 cannot generate pressure, so close the solenoid valve 110 to maintain a vacuum state in the first few seconds of driving, and open it again after generating pressure. The solenoid valve 110 flows in air to generate fine air bubbles.

The temperature sensor 108 is mounted on the temperature sensor base 107 to detect the temperature of the washing water in use and display the temperature to the user.

The washing water and air flowing into the pump head 113 are delivered to the multi-function bucket inlet 121 through the pump outlet 112 due to the pressure of the motor pump 100 . As shown in Figures 4A to 4C, the multifunctional bucket inlet 121 is formed at the lower end of one side of the multifunctional bucket 120, while the multifunctional bucket outlet 122 is formed at the upper end of the other side, and compared to that shown in Figures 4A to 4C The center line can be used at an angle (negative angle). This is to secure a space in the multi-function bucket 120 as shown in FIGS. 4A to 4C when the motor pump 100 is driven, and the rising air gathers there.

At this time, when the multifunctional water bucket 120 is inclined, it is preferable to incline in such a manner that the multifunctional water bucket inlet 121 side rises and the multifunctional water bucket outlet 122 side descends.

Fig. 5 is a structural diagram of the pressure valve provided according to the present invention. As shown in Figure 5, the pressure valve 130 includes: an inlet hole 132 provided at the pressure valve inlet 131 of the pressure valve 130, and a plurality of inlet and outlet holes 133 are formed on the side of the inlet hole 132; A base 134 that blocks the inlet hole 132; a base guide 135 that supports the base 134 and is formed with a base guide groove 139; one end supports the base guide 135 and the other end supports the pressure valve outlet The spring 137 of 138; the tapered outlet hole 136 blocked by the base 134 when the pressure of the motor pump 100 increases.

In addition, when the motor pump 100 is not driven, the multifunctional bucket 120 should also be kept at a certain water level so that the washing water is always accumulated in the multifunctional bucket 120, so that the suction (self-priming) can be activated when the microbubble generating device is restarted. ) work automatically.

Thus, if the motor pump 100 is driven, a certain amount of washing water in the multifunctional bucket 120 flows into the pressure valve 130 through the lower hole 124 of the multifunctional bucket, and flows through the inlet and outlet holes 133 of the pressure valve 130 and the base guide groove. 139 , the outlet hole 136 and the starting water pipe 114 of the motor pump 100 flow into the pump head 113 . Since the motor pump 100 is in the working state, the washing water continues to flow in the above manner, so that the water inlet nozzle 101 gradually sucks the washing water in the tub, and then the washing water will be sucked into the pump head 113 .

If the washing water on the side of the water inlet nozzle 101 is sucked into the pump head 113, a certain water pressure will be generated on the flow path behind the pump outlet 112, and the generation of the water pressure will push the base 134 of the pressure valve 130 to block the outlet. The hole 136 prevents the washing water from flowing into the starting water pipe 114 through the pressure valve 130 , thereby preventing the motor pump 100 from being in a vacuum state.

If pressure is generated at the multifunctional bucket 120, the washing water and air flow out through the outlet 122 of the multifunctional bucket, and the outflowing washing water and air flow into the nozzle inlet 149 of the water outlet nozzle 118 through the outlet pipe 115 and the outlet hose 117 , and the washing water and air flow through the pressure plate 146 to be pressurized and then pass through the grid assembly 153 while generating tiny air bubbles.

As shown in Figure 6, the nozzle cover 142 of the water outlet nozzle 118 is formed with a lower nozzle cover central hole 143, and an upper nozzle cover central hole 144 is integrally formed with the lower nozzle cover central hole 143. The upper part of the nozzle cover central hole 144 has a hook groove 145, and the lower grid support platform 151 is equipped with a hook 157, and the lower nozzle cover central hole 143 and the upper nozzle cover central hole 144 and the grid assembly 153 formed as one.

When the micro-bubble generating device configured as above is used repeatedly, the grid assembly 153 will be blocked by tiny dirt, foreign matter, skin cutin, etc. in the bathtub, and the grid assembly 153 needs to be replaced.

In order to easily replace the grid assembly 153, a nozzle inlet 149 is formed on the top of the nozzle main body 141, a spring fixing table 148 that can support a spring is arranged in the center of the nozzle inlet 149, and a nozzle spring 147 is arranged at the bottom of the spring fixing table 148. , a pressure plate 146 with a spring guide is provided at the bottom of the nozzle spring 147, a plurality of grid support platforms 155 are provided at the bottom of the pressure plate 146, grids 152 are arranged between the grid support platforms 155, and the grid assembly The lower end portion of 153 is provided with a lower grid support platform 151 with a hook 157 .
