Description

Microbubble generating device capable of adjusting inlet water pressure

The invention relates to a bathing device, in particular to a device capable of generating bubbles during bathing; the invention is suitable for a microbubble generating device in which the water pressure of the influent water is constant pressure or under pressure to achieve so-called microbubbles. The function of the milk bath.

The current micro-bubble milk bath is carried out by means of bathing and showering; the current micro-bubble bath is on the shower device, which is an air passage on the shower head, which communicates with the water flow channel at a vertical or an angle, using Wen's The Venturi Effect is implemented. When water flows, air is drawn into the water from the air passage. After mixing with water, it can achieve some micro-bubbles. However, the microbubbles in this way are different from the real micro-bubble milk bath. The patent for the showerhead microbubble is mainly Japanese, and related patents include Japanese Patent Publication Nos. 2006-116518, 2008-229516, 2010-284619 and 2012-528663.

As for the bathing method, the effect of dissolving air in water at the present time is best, and FIG. 7 is a basic system structure of the microbubble generating device of this technology, which is produced by the motor 30 sucking water from the bathtub 50 into the water pipe. 200; the inhaled water passes through the air inlet pipe 20, uses the Venturi Effec principle to draw in air and mixes with water, and the mixed water is compressed by the motor 30 to compress and dissolve the air in the pressure cylinder 40. In the water, the intake pipe 20 is provided with a one-way valve 21; the water after the dissolved air is introduced into the bathtub through the outlet pipe 210, and it can be seen that the water flowing out of the outlet pipe 210 is a large amount of white micro-bubble water. White micro-bubble water is commonly known as milk bath. All the microbubble generating devices that dissolve air in water under pressure have the basic structure shown in Figure 7. All the patents are also added to other components in this structure or in the system, or in each component. Detailed innovations can be found in Taiwan's new patent certificate numbers M332481, M312983, M312358, M282672, M274105, M288173, M290753, M293794 and M297228, and Taiwan Invention Patent No. I245667.

Since the microbubble milk bath is carried out by showering on the shower head with the microbubbles generated by the Venturi Effect, the actual microbubbles are not effective; while the microbubble milk bath is used for bathing, It is carried out in a way that the compressed air is dissolved in water, and the effect is very good, but few people take a bath every day, and the body is cleaned by shower when there is no bath.

The present invention is mainly aimed at solving the practical needs of people who sometimes take a bath and sometimes take a shower, and the effect of the microbubbles is maintained at a good level regardless of whether it is a bath or a shower. In addition, some homes do not have a bathtub at all, only shower facilities, and the present invention also provides a shower effect in which such a home can have a good microbubble milk bath.

The present invention is mainly directed to a bathing bath capable of simultaneously satisfying a change in the water inlet pressure and a bathing bath when the inlet water pressure is fixed. To achieve the object, the apparatus of the present invention comprises: a water pipe connected to the tap water system The tap water pipe is connected with a manual switch; a bathtub water pipe connected to the bathtub, the bathtub water pipe is connected with a manual switch; and a water pipe having a mixing water and water, and a balance valve is connected to the water pipe a T-shaped joint connecting the bathtub water pipe, the water pipe and one end of the water pipe; an intake pipe, one end of which is connected to the water pipe, and the other end is connected to the atmosphere, and is sequentially installed on the air inlet pipe a one-way valve and an electromagnetic valve; a motor, one end connected to the other end of the water pipe, the air pipe connecting the water pipe between the balance valve and the motor; a pressure cylinder connected to the other end of the motor, The pressure cylinder is provided with a pressure switch; an electromagnetic valve control line for connecting the pressure switch and the electromagnetic valve of the air inlet tube; One end is connected to the pressure cylinder; and one emulsification head is provided at the other end of the water outlet pipe.

If the shower is in the micro-bubble milk bath, tap water is used as the water supply source for the device. At this time, the pressure of the water inlet will be different due to the pressure of the water in the building due to the installation position of the device in the building. The water inlet pressure is small, and the water inlet pressure at the bottom of the building is large, and the water pressure is often in a state of change because of the different water conditions. Therefore, the water pressure of the microbubble generating device is different, and the pressure changes. The effect of microbubbles may be affected, but the valve device such as a balance valve or a pressure reducing valve or a water level adjusting cylinder may be installed to adjust the pressure fluctuation.

If the micro-bubble milk bath is bathed, the water is first stored in the bathtub to a certain fixed water level, and then the micro-bubble generating device is introduced into the water pipe for the water supply of the device; the micro-bubble water treated by the device is re-introduced into the bathtub. in. Since the water inlet system at this time uses the water storage in the bathtub, the water inlet pressure is fixed, and the system inlet water is in a stable state, although the inlet water will also pass through the balance valve or the pressure reducing valve, but at this time, the balance valve or the pressure reducing valve The importance of regulating pressure demand is greatly reduced.

As described above, since the present microbubble generating device is simultaneously suitable for shower and bathing needs, that is, the present invention can simultaneously satisfy the use of a bath when the water inlet pressure is fixed, and the shower demand in which the water inlet pressure is changed at any time.

The technical means adopted by the present invention for achieving the intended purpose of creation are further explained below in conjunction with the drawings and the preferred embodiment of the present invention.

The structure of FIG. 1 is the main implementation structure of the present invention. Therefore, the embodiment is described by the structure. The microbubble generating apparatus of the present invention includes:

a water pipe 110 connected to the water supply system; and a manual switch 71 is installed on the water pipe 110 for controlling the water supply of the device by the water pipe;

a bathtub water pipe 100 connected to the bathtub 50; and a manual switch 70 installed on the bathtub water pipe 100 for controlling the water inlet of the device from the bathtub 50;

a delivery pipe 120 provides mixing of micro gas and water, and feeds the mixed water into the motor 30;

a T-joint 10, which connects one end of the three water pipes, such as the bathtub water pipe 100 connected to the bathtub 50, the water pipe 110 of the water supply system (water tower 90), and the water and water mixing water supply pipe 120;

A balancing valve 60 is used for the pressure of the water in the shower or bath, thereby balancing the function of the valve to maintain the stability of the water at the rear end; the balancing valve 60 is installed in the water circuit. When the pressure difference entering the circuit changes, it is manually adjusted to open or close; the opening degree of the balancing valve 60 itself is used to change the absorption pressure difference or release the pressure difference, so that the pressure difference entering the circuit is stabilized, and the flow rate is stabilized. No traffic will be passed. The problem of losing control ability due to sudden change of pressure difference in the variable flow system can be properly solved; the balance valve 60 is installed in the water delivery pipe 120;

An intake pipe 20; and a one-way valve 21 is disposed on the intake pipe 20 to allow air to be sucked in one direction, and to prevent water from flowing out through the intake pipe 20; one end of the intake pipe 20 is connected to the water pipe 120 The other end is connected to the atmosphere;

An electromagnetic valve 22 is mounted on the intake pipe 20 for controlling the intake time;

A motor 30, in addition to providing the water inlet power of the device, and providing power for compressing air; one end of the motor 30 is connected to the other end of the water pipe 120, and the intake pipe 20 is connected to the water pipe 120 between the balance valve 60 and the motor 30. ;

a pressure cylinder 40, in which the air is compressed and dissolved in water; the pressure cylinder 40 is connected to the other end of the motor 30;

a pressure switch 41 is disposed in the pressure cylinder 40 for detecting the pressure in the pressure cylinder 40;

An electromagnetic valve control line 42 for connecting the pressure switch 41 and the electromagnetic valve 22 of the intake pipe 20, and controlling the time of intake of the intake pipe 20 by the pressure switch 41 signal;

An outlet pipe 130 is connected at one end to the pressure cylinder 40 and at the other end to an emulsification head 80 for use as a shower or a bath; by the above technical means, as shown in Fig. 1, it is connected to the tap water. The manual valve 71 on the tube 110 is opened, and the manual valve 70 from the bathtub water pipe 100 is closed. At this time, the motor 30 is actuated, and the device can be used as a shower for the microbubble milk bath.

On the contrary, the manual valve 71 connected to the water pipe 110 is closed, and the manual valve 70 connected to the bathtub water pipe 100 is opened. At this time, the motor 30 is activated, and the device can be used as a bath for the microbubble milk bath.

When the bubble milk shower is to be performed, as shown in FIG. 5, the manual valve 71 connected to the water pipe 110 is first opened, and the manual valve 70 connected to the bathtub water pipe 100 is closed. At this time, the motor 30 is started, and the device is That is to say, it started to operate. At this time, tap water is used as a source of water supply.

After the motor 30 is started, the water is supplied from the water tower 90, and the water is introduced through the water pipe 110. Since the water tower 90 is required to supply other floors at the same time, the water pressure entering the water pipe 110 is unstable, and therefore, the device uses the balancing valve 60 as the balance valve 60. Adjusted; the adjusted water enters the delivery tube 120. The conveying pipe 120 is connected to the intake pipe 20. Due to the water flow, by the Venturi Effect, when the electromagnetic valve 22 is opened, the air is sucked into the conveying pipe 120 via the intake pipe 20 to mix with the water. The water after mixing the air enters the motor 30.

A one-way valve 21 is disposed on the intake pipe 20 to allow air to enter the delivery pipe 120 in one direction, and to prevent water from flowing out of the delivery pipe 120 via the intake pipe 20.

When the water after the mixed air enters the motor 30, the motor 30 performs a second mixing of air and water by mechanical force, and after mixing by the motor 30, the air and water are mixed better. This second mixed water is then introduced into the pressure cylinder 40. Under the high pressure of the pressure cylinder 40, the gas will dissolve in the water.

A pressure switch 41 is disposed in the pressure cylinder 40 to detect the pressure value in the pressure cylinder 40. When the internal pressure is higher than the set upper limit due to excessive water in the pressure cylinder 40, the electromagnetic valve control line 42 is used. The signal control, the electromagnetic valve 22 is opened, and the intake pipe 20 starts to take in air to balance the pressure in the pressure cylinder 40 with the introduced air; if the amount of air in the pressure cylinder 40 is too large, the pressure of the pressure cylinder 40 is lower than the setting. At the lower limit value, the electromagnetic valve 22 is closed by the signal control of the solenoid valve control line 42, and the intake pipe 20 is closed and no longer intake. That is, when the intake pipe 20 is ingested, it is controlled by the pressure conditions within the pressure cylinder 40.

The water in the air cylinder 40 is guided by the outlet pipe 130, and the water is ejected by the emulsification head 80. The water sprayed in the water is reduced by external pressure, and the air dissolved in the water becomes microbubbles, forming microbubble water. For showers, microbubbles are called milk baths because they are white like milk.

The plug 51 in the bathtub 50 will be removed during the shower, so the water after the shower will be drained and will not be recycled.

To make a bath, as shown in Fig. 6, the plug 51 is first plugged, and the bathtub 50 is stored in tap water to an appropriate water level. Then, the manual valve 71 connected to the water pipe 110 is closed, and the manual valve 70 connected from the water pipe 100 in the bathtub is opened. At this time, the motor 30 is started, and the water of the bathtub flows through the T-joint 10 and the pressure reducing valve in sequence. 61. The water pipe 120, the motor 30, the pressure cylinder 40, the water outlet pipe 130 and the emulsification head 80 are returned to the bathtub 50 to achieve circulation of the bathtub water, and the device can be used as a bath for the microbubble milk bath. The microbubble generating mechanism after the motor 30 is turned on is exactly the same as the aforementioned shower, and the description will not be repeated, except that the water in the bath is circulating water, unlike the shower, the water is drained.

If the manual valves 70 and 71 are both closed, if the motor 30 is turned on, the motor 30 will be idling. Therefore, in order to avoid damage to the motor 30 due to idling, the motor selected by the device is a motor that can be operated under idling conditions, that is, Under idling conditions, the motor will not burn.

The structure of Fig. 1 uses the balancing valve 60 as an element for adjusting the inlet pressure, and can also meet the requirement of adjusting the inlet pressure with other components; as shown in Fig. 2, if the pressure reducing valve 61 (Pressure Reducing Valve) is used instead The balance valve 60 can be used for the adjustment of the water inlet pressure, and can also achieve the shower and bath function of the microbubble milk bath. The pressure reducing valve 61 is a valve device that adjusts the inlet pressure to a desired outlet pressure and relies on the energy of the medium itself to automatically maintain the outlet pressure. From the viewpoint of fluid mechanics, the pressure reducing valve 61 is a throttling element whose local resistance can be changed, that is, by changing the throttling area, the flow rate and the kinetic energy of the fluid are changed, resulting in different pressure loss, thereby achieving the purpose of decompression. Then, relying on the adjustment of the control and regulation system, the fluctuation of the post-valve pressure is balanced with the spring force, so that the post-valve pressure remains constant within a certain error range. The structure of Fig. 2 is a pressure reducing valve 61 instead of the balancing valve 60 of Fig. 1, and both the balancing valve 60 and the pressure reducing valve 61 can be used for pressure regulation of the apparatus. The shower and bath embodiment of the structure of the pressure reducing valve 61 of Fig. 2 is completely the same as the shower and bathing embodiment of the balancing valve structure of Fig. 1, and therefore will not be described again.

In addition to adjusting the pressure by the valve device, the pressure can be adjusted by the action of the liquid level switch. As shown in FIG. 3, a water level adjusting cylinder 140 is installed between the T-joint 10 and the water pipe 110, and the water level adjusting cylinder 140 is installed in the water level adjusting cylinder 140. The liquid level switch 141 opens the electromagnetic valve switch 142 to enter the water when the water level is low to the lower limit. When the liquid level is high to the upper limit, the liquid level switch 141 turns off the electromagnetic valve switch 142 to stop the water inlet, so that the liquid level can be controlled at The pressure entering the inside of the device can be controlled properly between the upper and lower limits. The structure of FIG. 3 is to control the water level in the water level adjusting cylinder 140 by the liquid level switch 141 and the electromagnetic valve switch 142 to control the water inlet pressure flowing into the device; as shown in FIG. 3, the water level adjusting cylinder 140 has a liquid level switch. 141, when the water level is too low, the liquid level switch 141 opens the electromagnetic valve switch 142 via the signal of the electromagnetic valve control line 43, the electromagnetic valve switch 142 is connected to the water pipe 110, and the tap water is injected into the water level adjusting cylinder 140; When the height reaches the upper limit, the liquid level switch 141 turns off the solenoid valve switch 142 via the signal of the electromagnetic valve control line 43, and stops the tap water from being injected into the pressure regulating cylinder 140. When the liquid level is controlled within a range of upper and lower limits, the pressure change is within a certain value and does not affect the microbubbles in the latter stage. It must be noted that the amount of water in the tap water must be higher than the amount pumped by the motor. The liquid level switch is a well-known technology, and its function and structure are not described. Fig. 3 shows the mechanism and structure of the bubble generation after the water is introduced, which is the same as the case of using the valve described above, and will not be described again.

In addition, the water level adjusting cylinder 140 of FIG. 3 can also be used for the conventional floating ball type mechanical control liquid level. As shown in FIG. 4, the floating ball type liquid level control mechanism is widely used in the toilet flushing system, and the design can also be maintained. The pressure inside the device can be controlled properly. The float ball mechanism of Fig. 4 completely controls the water level in the water level adjusting cylinder 150 mechanically. When the water ball 151 drops to the lower limit due to the water level, the water inlet switch is opened to allow the tap water to flow into the water level adjusting cylinder 150; 151 When the water level rises to the upper limit, the water inlet switch will be closed to stop the water inlet, so that the water level can be controlled, and the pressure change is within a certain value, which will not affect the microbubbles in the latter stage, because the floating ball type structure is widely used. The toilet water inlet device has been a well-known technique and will not be described.

The device of the present invention is used for showering with tap water as a source of water supply. Tap water may cause tap water to enter due to different positions of the device, for example, in different floor positions in the building, or because other users in the same building are using water or the like. The water pressure to the device may be different, and the valve device such as the balance valve 60 or the pressure reducing valve 61 or the water level adjusting cylinder 140 may be installed to adjust the pressure fluctuation. When the device is used for bathing, the water is first stored in the bathtub, and then the microbubble water produced by the device is introduced into the bathtub in a circulating manner. Therefore, the water level of the bathtub does not change. At this time, the pressure of the water entering the device is not changed. For a fixed value, although the water flow still passes through the balancing valve 60 or the pressure reducing valve 61, the importance of adjusting the pressure demand of the balancing valve or the pressure reducing valve is greatly reduced. The system can maintain a stable state.

The above description is only a preferred embodiment of the present invention, and does not impose any form limitation on the present invention. Although the present invention has been disclosed above in the preferred embodiment, it is not intended to limit the present creation, and has any technical field. A person skilled in the art can make some modifications or modifications to equivalent embodiments by using the above-disclosed technical contents without departing from the technical scope of the present invention.
