[0015] In order to make the purpose, technical scheme and advantage of the utility model more clear, the following will combine the specific embodiment of the utility model and the corresponding drawings to clearly and completely describe the technical scheme of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skill in the art without making creative labor belong to the protection scope of the utility model.

[0016] Although the utility model specification can include a variety of different forms of embodiment, and for the preferred embodiment of some in the specification detailed description and shown in the drawing, it should be understood that: the utility model specification disclosed should be regarded as the illustrative description of the principle of the utility model, and these shown embodiments are not to limit the scope of the utility model to be protected.

[0017] The following will be combined with the drawings, and the technical scheme provided by each embodiment of the utility model will be described in detail.

[0018] According to the utility model embodiment, a gas liquid mixing device based on venturi structure is proposed, referring to Figure 1 And Figure 2 The gas liquid mixing device has a shell 1, and the shell 1 includes a first section structure 11 and a second section structure 12 communicated with the first section structure 11.

[0019] The first section structure 11 can also be referred to as a contraction section, and is a tapered (horn) structure including a proximal end and a distal end, and the inner diameter gradually decreases from the proximal end to the distal end. The proximal end of the first section structure 11 is in communication with the water inlet 2 of the water inlet channel, and the distal end of the first section structure 11 is provided with a micro-hole 13. Water flows into the first section structure 11 through the water inlet 2, and the flow rate of the water increases when passing through the micro-hole 13, so that the pressure around the micro-hole 13 decreases to form a negative pressure.

[0020] The second section structure 12 can also be referred to as a diffusion section, and is a tapered (horn) structure including a proximal end and a distal end, and the inner diameter gradually increases from the proximal end to the distal end. The proximal end of the second section structure 12 is in communication with the distal end of the first section structure 11, and the distal end of the second section structure 12 has a gas-liquid mixing outlet 15.

[0021] As shown in the drawings, the micro-hole 13 is arranged near the connection between the first section structure 11 and the second section structure 12, and the micro-hole 13 is in communication with the air inlet channel. Specifically, the air inlet channel includes an air inlet 31, an air inlet electromagnetic valve 32 and a one-way valve 33. The air inlet electromagnetic valve 32 is used to control the on-off of the air path, and the one-way valve 33 is used to prevent water from entering the air inlet channel when the flow rate of the water is too large. The gas-liquid mixing device sucks air into the micro-hole 13, so that the gas and the liquid are mixed and flow out from the gas-liquid mixing outlet 15.

[0022] In the embodiment of the present application, the gas-liquid mixing device is used to generate or produce micro-bubbles, which are bubbles with a diameter of 1-100 microns. The stability of the micro-bubble effect is directly related to the air inlet amount, and the more stable the air inlet amount is, the more stable the micro-bubble effect is. The key factor affecting the air inlet amount is the size of the micro-hole 13 in the gas-liquid mixing device (i.e. the Venturi structure). Under a certain water flow rate, if the micro-hole 13 is too large, the flow rate through the micro-hole will increase, which will cause the air inlet to be unable to enter the water. If the micro-hole 13 is too small, the flow rate through the micro-hole will decrease, which will cause the negative pressure around the micro-hole 13 to decrease, and thus the air inlet amount will not be enough. Therefore, it is necessary to set a micro-hole with a reasonable size for the stability of the micro-bubble effect. Please refer to Table 1 below.

[0023] Table 1

[0024]

[0025] Table 1 shows the relationship between the micro-hole size and the flow rate and micro-bubble effect after the Venturi structure. A large number of experiments show that (the length of the second structure in the test is 38mm) when the micro-hole diameter is 2.3mm, the air intake is 0, and there is no micro-bubble effect. When the micro-hole diameter is 1.6mm, the air intake and bubble density are low, the bubble duration is about 1 minute and 30 seconds, and the micro-bubble effect is poor. When the diameter of the micro-hole is between 1.7-2.1mm, the air intake and bubble density reach a relatively maximum value, the bubble disappears completely for more than 2 minutes, and the micro-bubble effect is best. Therefore, when the micro-hole diameter is between 1.7-2.1mm, the stability of the micro-bubble duration can be ensured.

[0026] The gas-liquid mixing device or jet according to the embodiments of the present application can be provided (or integrated) in a water purification device (such as a water purifier or water purifier), so that the water purification device can generate and flow out micro-bubble water. In this way, the demand for miniaturizing the gas-liquid mixing device as small as possible without affecting the micro-bubble effect is proposed.

[0027] The second structure of the gas-liquid mixing device mainly functions to reduce the flow rate of the water flow (gas-liquid mixing) through the micro-hole by the channel with an increasing inner diameter, so as to restore the flow rate and pressure before entering the device. Therefore, whether the length and slope of the second structure are appropriate will directly affect the stability of the water flow, and if this section is set too long, the gas-liquid mixing device will also be too large in size or length, occupying space.

[0028] Table 2

[0029] Second segment length 38 mm 60 mm Flow rate before venturi structure 2.66 L / min 2.66 L / min Flow rate after venturi structure 2.72 L / min 2.70 L / min Bubble duration 2 min 20 s 2 min 15 s

[0030] Table 2 shows the corresponding relationship between the flow rate and bubble effect of the Venturi structure corresponding to the length of the second structure of 38mm and 60mm. According to a plurality of experiments (the size of the micro-hole in the test is 2.1mm), the length of the second structure of the Venturi structure is between 35-45mm, and the slope is between 1.9-2.0 degrees, which can achieve the flow rate and micro-bubble effect basically consistent with the length of 60mm. Only the data corresponding to the length of the second structure of 38mm is shown in Table 2. The present application can achieve the flow rate and bubble effect of the structure with a longer length (60mm) by setting a shorter length (38mm) of the second structure, and realizes the miniaturization of the gas-liquid mixing device without affecting the micro-bubble effect of the device.

[0031] According to the utility model embodiments still propose a kind of jet flow ware, the jet flow ware includes water inlet channel, air inlet channel and the gas-liquid mixing device described above, here no longer repeat.The drawings, wherein, the water inlet of the water inlet channel 2 is communicated with the proximal end of the first section structure 11 of gas-liquid mixing device.Reference arrows in Figure 2

[0032] In conclusion, according to the two-section gas-liquid mixing device provided by the utility model, water is inhaled through the proximal end of the first section structure, air is inhaled at the micropore of the distal end of the first section structure to realize gas-liquid mixing, and in the second section structure, the water flow is restored to the flow rate and pressure before entering the pipe structure, the present application can obtain micro-bubble water with stable bubble duration by reasonably setting the size of the micropore.And the miniaturization of the gas-liquid mixing device is realized without affecting the micro-bubble effect of the device.
