Description

Technical Field

[0001] The utility model relates to a water outlet device of a water purifier, in particular to a bubble water generating device. Background Art

[0002] At present, the application of microbubble water has gradually developed into the field of water purification. At present, the gas mixing of the microbubble water generating device is mainly divided into powered and unpowered. The powered mixing method generally uses a small pump body to pressurize the gas and press it into the water path of the water purifier; unpowered mixing generally uses the Bernoulli principle to use high-speed flowing liquid to create a negative pressure area, suck the gas into the water flow, and realize automatic suction and automatic mixing. This device using the Bernoulli effect is generally called a Venturi tube. Compared with the pump body pressurization, the Venturi tube has the advantage of not requiring additional power.

[0003] In addition, the device for generating bubble water generally mixes air, which will cause a problem, that is, there will be some impurities in the air, floating bacteria, particles, colloids, etc. mixed with the air into the water body, causing harm to the water quality, so it is necessary to filter the air. Generally, in order to solve this problem, air filter media is used for filtration, such as PP cotton, PP electret non-woven fabric, etc. However, this filtering method has two basic problems:

[0004] First, the air resistance is large, resulting in low intake efficiency, and a supercharging device is often required;

[0005] Second, it is easy to get dirty and fail after long-term use. Because the working conditions of water purifiers are often humid, the filter material is prone to breed bacteria. Utility Model Content

[0006] The first technical problem to be solved by the utility model is to provide a bubble water generating device capable of better filtering dust particles in bubble water in view of the above-mentioned existing technical status.

[0007] The second technical problem to be solved by the present invention is to provide a water purifier using the above-mentioned bubble water generating device in view of the above-mentioned existing technical status.

[0008] The technical solution adopted by the utility model to solve the above-mentioned first technical problem is: the bubble water generating device comprises:

[0009] A shell, the shell comprising a water inlet end and a water outlet end;

[0010] Features:

[0011] The bubble generating member is arranged on the water flow path between the water inlet end and the water outlet end of the shell, and the bubble generating member includes a venturi tube, the inlet end of the venturi tube is sealed and connected to the water inlet end of the shell, and the outlet end of the venturi tube is the outflow channel for the water flow to entrain microbubbles. In addition, an air inlet is also provided on the side wall of the inlet end of the venturi tube, so that under the action of the local vacuum generated by the venturi tube, air is sucked into the venturi tube to generate microbubbles.

[0012] In order to realize the Venturi effect, preferably, along the flow direction of the water flow, the cross section of the inlet end of the Venturi tube includes a convergent section with a gradually decreasing diameter and a straight section connected to the convergent section. The outlet end of the straight section is the outflow channel for the water flow to carry microbubbles, and the air inlet is arranged on the straight section. The Venturi tube can be a traditional Venturi tube, that is, including a convergent section and an expansion section, or it can be a straight section as mentioned above instead of an expansion section. The water flow is accelerated through the convergent section. Since the diameter of the straight section is smaller than that of the convergent section, the water flow coming out of the convergent section is accelerated in a concentrated manner, and the vacuum degree is increased, thereby forming a certain vacuum in the Venturi tube, significantly reducing the pressure on the water flow, so that the air sucked into the Venturi tube quickly overflows in large quantities to form micro bubbles of water, thereby achieving the bubbling effect.

[0013] In order to ensure that the air entering the venturi tube is dust-free, preferably, the air inlet is connected to a separation device for separating dust particles from the air sucked into the venturi tube. The air is separated and purified by combining the venturi device and the separation device, and an additional power source for gas separation is omitted, thereby reducing the complexity of the system and improving the effectiveness of the system.

[0014] From the perspective of the implementation of the separation device, preferably, the separation device includes a main body, on which is provided a cyclone chamber for separating dust from incoming air, a dust collecting chamber arranged adjacent to the cyclone chamber for collecting dust particles separated from the air, and an air guide between the cyclone chamber and the dust collecting chamber for allowing dust-free air to leave the cyclone chamber and enter the air inlet.

[0015] The structure of the cyclone chamber can be of various kinds. From the perspective of faster separation, preferably, the cyclone chamber is cone-shaped so that the dust-laden air can swirl inside it along the side walls.

[0016] In order to enable the dust-laden air to flow into the cyclone chamber, preferably, the main body is further provided with an inflow portion for enabling the dust-laden air to flow into the cyclone chamber.

[0017] In order to increase the speed at which the dust-laden air flows into the cyclone chamber, preferably, along the inflow direction of the air, the cross section of the inflow portion gradually decreases.

[0018] In order to filter the dust-laden air before it flows into the cyclone chamber, preferably, the air inlet of the inflow portion is provided with a filter element for filtering.

[0019] In order to enable dust-free air to enter the Venturi tube faster, preferably, the air inlet is confined within the air pipe, and the cross-section of the air pipe gradually decreases from the air inlet.

[0020] In order to solve the second technical problem, the utility model provides a water purifier, including a shell, characterized in that the outlet of the drain pipe in the shell is connected to the bubble water generating device as mentioned above.

[0021] Compared with the prior art, the utility model has the advantages that: by arranging a venturi tube capable of sucking air into the shell of the purifier, the water flow can form more microbubbles, and the structure has a more compact effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0026] like Figures 1 to 3 The best embodiment of the utility model is shown in FIG. 1 . The bubble water generating device of the present embodiment comprises a housing 1, the housing 1 comprises a water inlet end 11 and a water outlet end 12, a bubble generating member is further provided on the water flow path between the water inlet end 11 and the water outlet end 12 of the housing 1, the bubble generating member comprises a venturi tube 2, the inlet end 22 of the venturi tube 2 is sealedly connected to the water inlet end 11 of the housing 1, and the outlet end 21 of the venturi tube 2 is the outflow channel for the water flow to entrain microbubbles, in addition, an air inlet 3 is further provided on the side wall of the inlet end 22 of the venturi tube 2, so that under the action of the local vacuum generated by the venturi tube 2, air is sucked into the venturi tube 2 to generate microbubbles, and by providing a member in the housing 1 of the purifier that can suck air into the venturi tube 2, the water flow can form more microbubbles.

[0027] Specifically, in order to achieve the Venturi tube 2 effect, along the flow direction of the water flow, the cross section of the inlet end 22 of the Venturi tube 2 includes a convergent section 23 with a gradually decreasing diameter and a straight section 24 connected to the convergent section 23. The outlet end 21 of the straight section 24 is the outflow channel for the water flow to carry microbubbles. The air inlet 3 is arranged on the straight section 24. The straight section 24 of the Venturi tube 2 replaces the expansion section. The water flow is accelerated through the convergent section 23. As the diameter of the straight section 24 is smaller than that of the convergent section 23, the water flow coming out of the convergent section 23 is accelerated, and the vacuum degree is increased, thereby forming a certain vacuum in the Venturi tube 2, so that the pressure on the water flow is significantly reduced, so that the air sucked into the Venturi tube 2 quickly overflows in large quantities, forming micro-water bubbles, thereby achieving the effect of bubbling. In addition, in order to realize that the air entering the Venturi tube 2 is dust-free air, the air inlet 3 is connected to a separation device 4 for separating dust particles from the air sucked into the Venturi tube 2. The air is separated and purified by combining the Venturi device with the separation device 4, and an additional power source for gas separation is omitted, thereby reducing the complexity of the system and improving the effectiveness of the system.

[0028] From the perspective of the realization of the separation device 4, the separation device 4 of this embodiment includes a body 41, on which a cyclone chamber 42 for separating dust from incoming air is provided, a dust collection chamber 43 arranged adjacent to the cyclone chamber 42 for collecting dust particles separated from the air, and an air guide 44 between the cyclone chamber 42 and the dust collection chamber 43 for allowing dust-free air to leave the cyclone chamber 42 and enter the air inlet 3, wherein the cyclone chamber 42 is cone-shaped, and dust-containing air can swirl inside along the side wall. The body 41 is also provided with an inflow portion 45 for allowing dust-containing air to flow into the cyclone chamber 42, so as to achieve dust-containing air flowing into the cyclone chamber 42. In addition, in order to increase the speed at which dust-laden air flows into the cyclone chamber 42, the cross-section of the inlet portion 45 gradually becomes smaller along the inflow direction of the air, and a filter element 5 for filtering is provided at the air inlet of the inlet portion, so that the dust-laden air can be filtered before it flows into the cyclone chamber 42. Finally, dust-free air can enter the Venturi tube 2 faster, and the air inlet 3 is restricted in the air pipe 6, and the cross-section of the air pipe 6 gradually becomes smaller from the air inlet 3.

[0029] The present embodiment also provides a water purifier, which includes a shell, and the outlet of the drain pipe in the shell is connected to the bubble water generating device as mentioned above. When the bubble water generating device is in use, first, along the flow direction of the water flow in the drain pipe, due to the local vacuum generated in the venturi tube 2, the dust-free air separated by the separation device 4 is sucked into the venturi tube 2 to generate microbubbles.
