Description

This disclosure relates to a bubble-containing liquid generating apparatus, and more particularly to a bubble-containing liquid generating apparatus that generates a bubble-containing liquid. In recent years, the use of bubble-containing liquids, which contain minute bubbles in a liquid, has been increasing. Patent Document 1 describes a conventional bubble-containing liquid manufacturing apparatus. The bubble-containing liquid manufacturing apparatus described in Patent Document 1 comprises a pressurized dissolution tank, a bubble generation unit, and a shearing mechanism unit. The pressurized dissolution tank receives liquid from a liquid supply line, and gas is pressurized and supplied from a gas injection unit to generate a pressurized liquid in which the gas is dissolved. The bubble generation unit reduces the pressure of the pressurized liquid supplied from the pressurized dissolution tank. The shearing mechanism unit applies a shearing force to the bubble-containing liquid. Japanese Patent Publication No. 2021-23910 Figure 1 is a schematic diagram of the bubble-containing liquid generating apparatus according to Embodiment 1.Figure 2 is a functional block diagram of the control circuit in the bubble-containing liquid generating apparatus described above.Figure 3 is a functional block diagram of the control circuit in a bubble-containing liquid generating apparatus according to a modified example of Embodiment 1.Figure 4 is a schematic diagram of the bubble-containing liquid generating apparatus according to Embodiment 2.Figure 5 is a schematic diagram of a bubble-containing liquid generating apparatus according to another modified example 1. The bubble-containing liquid generating apparatus according to the embodiments of this disclosure will be described in detail below with reference to the drawings. However, the figures described in the following embodiments are schematic diagrams, and the ratios of the size and thickness of each component do not necessarily reflect the actual dimensional ratios. Furthermore, the configurations described in the following embodiments are merely examples of this disclosure. This disclosure is not limited to the following embodiments, and various modifications are possible depending on the design, etc., as long as the effects of this disclosure can be achieved. (Embodiment 1) (1) Configuration of the bubble-containing liquid generating apparatus Figure 1 is a schematic diagram showing the configuration of the bubble-containing liquid generating apparatus 1 according to Embodiment 1. The bubble-containing liquid generator 1 is a device that generates bubble-containing liquids. A bubble-containing liquid is a liquid that contains bubbles. Bubbles contained in a liquid are named differently depending on their size. For example, bubbles with a diameter of 100 μm or less are called fine bubbles. Furthermore, among fine bubbles, bubbles with a diameter of less than 1 μm are called ultrafine bubbles, and bubbles with a diameter of 1 μm or more are called microbubbles. The bubble-containing liquid generator 1 generates, for example, ultrafine bubble water, which contains ultrafine bubbles in the liquid. The ultrafine bubble water generated by the bubble-containing liquid generator 1 can be produced, for example, by using water as the liquid and air as the gas that forms the bubbles. As shown in Figure 1, the bubble-containing liquid generating apparatus 1 includes a nozzle 2, a housing 3, a pressurized container 4, a pressure detection unit 41, a liquid supply unit 5, an outlet path 6, and a discharge control unit 7. The housing 3 is a case that houses the pressurized container 4, the pressure detection unit 41, the liquid supply unit 5, a portion of the outflow path 6, and a portion of the discharge control unit 7. The housing 3 also has an inlet 511, which is a through-hole communicating with the liquid container 51 of the liquid supply unit 5. A lid 31 is detachably attached to the inlet 511. Furthermore, the housing 3 is provided with a through-hole 32 for exposing the discharge switch 71 of the discharge control unit 7 to the outside of the housing 3, and a through-hole 33 for exposing a portion of the outflow path 6 to the outside of the housing 3. The housing 3 is made of, for example, resin. The pressurized container 4 is a container that generates pressurized liquid L2 by dissolving gas G1 under pressure in liquid L1. Pressurized dissolution refers to dissolving gas G1 in liquid L1 by bringing it into contact with liquid L1 under a pressure environment higher than atmospheric pressure (1 atmosphere). For example, if liquid L1 is water and gas G1 is air, the pressurized liquid L2 is water with air dissolved in it under pressure. The pressurized container 4 is connected to a liquid supply unit 5, a pressure detection unit 41, and an outlet path 6. The pressurized container 4 is sealed except for the connections between the liquid supply unit 5, the pressure detection
