Detailed Description

The invention is described in further detail below with reference to the accompanying examples.

The bubble water generating device in the embodiment can be applied to various environments which can be connected with a water source and have bubble water requirements, such as being connected in a water supply pipe of a water pipe, and also being connected in a water path structure of an electric appliance, such as being used in a water path of a gas water heater.

As shown in fig. 1 and 2, the bubble water generating apparatus includes a base pipe 1 and a mixer 2.

Wherein the base pipe 1 is internally provided with a fluid passage 101 for water and gas to enter, and also comprises a flow passage arranged around the periphery of the passage, and the outer wall of the base pipe 1 is also provided with a water outlet 103 communicated with the bubble water flow passage 102.

In this embodiment, the base pipe 1 includes an inner core pipe 11 and an outer shell pipe 12, the outer shell pipe 12 is sleeved outside the inner core pipe 11, a fluid passage 101 is arranged in the inner core pipe 11 in a penetrating manner, wherein a first end of the fluid passage 101 is used for connecting an air inlet pipe, and a second end of the fluid passage 101 is used for connecting an water inlet pipe. A gap is formed between the inner wall of the outer sheath tube 12 and the outer wall of the inner core tube 11, and the gap forms a bubble water flow passage 102. The inner core tube 11 is provided with a plurality of small holes 111 along the circumferential direction near the air inlet end, and the small holes 111 form a small hole area on the inner core tube 11. The water outlet 103 is arranged on the shell close to the water inlet end, and the water outlet 103 is used for connecting a water supply pipeline so as to provide bubble water. In order to ensure the sealing property of the bubble water flow passage 102, the inner core tube 11 and the outer shell tube 12 in this embodiment are sealed at both ends by their own structures. The outer shell tube 12 in this embodiment is provided with a first step 121 radially inwardly around the inner wall near the gas inlet end, and the inner core tube 11 is inserted into the outer shell tube 12 with the end abutting against the first step 121. The outer shell tube 12 is provided with a third step 122 radially extending outward on the inner wall close to the water inlet end, an installation head 113 is radially and outwardly protruded on the outer peripheral wall of the inner core tube 11, the installation head 113 is just abutted against the third step 122, and the inner core tube 11 and the outer shell tube 12 are fixedly connected by steel wire buckles.

The pressure stabilizing spring is arranged in the bubble water flow channel 102, so that bubble water is more fully mixed in the flowing process, and the uniformity of bubbles in the bubble water is improved.

The mixer 2 is arranged inside the base pipe 1, and a mixing cavity 201 is formed between the outer wall of the mixer 2 and the inner wall of the base pipe 1 in an enclosing manner. The mixer 2 is provided with a water inlet 21 for supplying water into the mixing chamber 201, the mixer 2 is also provided with a gas inlet 22 for supplying gas into the mixing chamber 201, and the gas inlet 22 can be opened and closed.

The length of the mixer 2 is smaller than that of the core tube 11 in this embodiment, and the mixer 2 is disposed at one end of the fluid passage 101 near the gas inlet end. The concrete structure of the mixer 2 is as follows: mixer 2 is one end open-ended body, and mixer 2 seals the setting near the first end of inlet end, and mixer 2 is close to the second end opening setting of intaking the end. The outer peripheral wall of the first end of the mixer 2 is provided with a first flange 23 of the periphery in a radial outward protruding manner, the outer peripheral wall of the second end of the mixer 2 is provided with a second flange 24 in a radial outward protruding manner, the first flange 23 and the second flange 24 are attached to the inner wall of the inner core tube 11, the inner walls of the first flange 23, the second flange 24 and the inner core tube 11 are arranged, and the outer wall of the mixer 2 is surrounded to form a mixing cavity 201. The mixing chamber 201 is positioned corresponding to the small hole 111 of the inner core tube 11, so that the small hole 111 can communicate the mixing chamber 201 and the bubble water flow passage 102. The outer peripheral wall of the first flange 23 is uniformly provided with a plurality of spirally distributed notches, and the notches and the inner wall of the inner core tube 11 form the air inlet 22, i.e. the air inlet 22 is arranged on the first flange 23. The water inlet 21 is arranged on the second flange 24 and/or the wall of the mixer 2. The water inlet 21 in this embodiment is disposed on the pipe wall of the mixer 2, and then the water flowing into the mixer 2 flows into the mixing cavity 201 through the water inlet 21, and then forms a hedging with the air entering from the air inlet 22 on the first flange 23, so as to realize the mixing of the air and the water, and further form bubble water. And the large bubbles in the bubble water can be over-broken when passing through the small holes 111 on the inner core tube 11, thereby forming fine small bubbles.

In order to prevent water entering the mixing chamber 201 from flowing out of the inlet 22, the inlet 22 of the mixer 2 can be switched on and off, specifically: the mixer 2 is supported against the first step 121 by an elastic member 3, which is capable of moving axially, and in order to facilitate the installation of the elastic member 3, one end of the elastic member 3 extends into the cavity of the mixer 2 and is supported against an end face of the seal. A circle of second steps 112 is radially and inwardly convexly arranged on the inner wall of one end of the inner core tube 11 close to the water inlet end, and the other end of the elastic element 3 is abutted against the second steps 112. When gas is introduced from the outside, the mixer 2 is pressed to move towards the water inlet end under the action of the air pressure, so that a gap is formed between the first flange 23 of the mixer 2 and the step surface of the first step 121, the gas enters the gas inlet 22 from the gap and enters the mixing cavity 201 through the gas inlet 22, and water in the mixing cavity 201 cannot flow out from the gas inlet 22 due to the existence of the gas pressure. When no gas is fed into the mixing chamber 201 from the outside, the first end of the mixer 2 is no longer pressurized, and the mixer 2 is pushed by the elastic member 3 to move axially toward the gas inlet end. The first flange 23 abuts against the first step 121, so that the air inlet 22 is closed, and the water in the mixing chamber 201 does not flow out of the air inlet 22.

The outer end surface of the second end of the mixer 2 in the embodiment is arranged in a convex conical shape, so that the air can be conveniently guided to flow towards the air inlet 22, and the air inflow is improved.

The working process of the bubble water generating device is as follows: let in gas when letting in rivers in fluid passage 101, rivers enter into the hybrid chamber 201 through water inlet 21 on the blender 2, and gas enters into the hybrid chamber 201 through air inlet 22 on the blender 2, and gas and water carry out the hedging in the hybrid chamber 201 and mix and then form bubble water, and this bubble water flows into to bubble rivers say 102 in after passing through the refining effect of the aperture 111 on the inner core pipe 11 to the bubble, and then outwards supplies bubble water through delivery port 103.

When water flows through the fluid passage 101 in the base pipe 1, the bubble water generating device simultaneously mixes air, and then the bubble water is directly generated in the flowing process of water. So generate the in-process rivers of bubble water and do not stop flowing, the bubble water yield that the unit produced is less, the air quantity that needs is little, the atmospheric pressure that the in-process that generates bubble water needs is lower, then need not to set up the booster pump and can accomplish the formation of bubble water in real time, so this bubble water generating device can use in the various service environment that can connect the water source, parent tube 1 wholly is the tubulose in addition, but the lug connection uses as the body in the pipeline, the miniaturization setting has been realized, wide application.
