[0056] The utility model will be explained more clearly and completely by the way of examples and in connection with the drawings, but the utility model will not be limited in the scope of the examples by this.
[0057] Example 1
[0058] A water tank, which comprises a tank body, an accommodating cavity is arranged in the tank body, and the accommodating cavity is communicated with the outside through an air inlet and outlet on the tank body. The water tank further comprises a dust removal device, which is installed on the air inlet and outlet.
[0059] As shown in Figures 1-5 , the dust removal device 100 comprises a shell 1, a cyclone cavity 11 extending vertically is arranged in the shell 1, an outlet 102 is arranged in the middle of the upper end face of the shell 1, the outlet 102 is communicated with the air inlet and outlet, an inlet 101 is arranged on the side wall of the shell 1, and the inlet 101 is communicated with the outlet 102 through the cyclone cavity 11. The dust removal device 100 is installed on the air inlet and outlet of the water tank, when the dust-containing air from the outside enters the cyclone cavity 11 through the inlet 101, the air will rotate in the cyclone cavity 11, with the increase of the rotating speed, the dust particles are thrown to the wall due to their large inertia, when the dust particles reach the wall, they will be subjected to a downward gravity, thereby being separated, and the clean gas can smoothly enter the accommodating cavity of the water tank from the outlet 102, finally, the separated dust particles will be gathered at the bottom of the shell 1, the dust removal device 100 has simple structure, convenient operation and low maintenance cost.
[0060] As shown in Figure 4 and Figure 5 , the upper end inner wall of the shell 1 has a central tube 12 extending downward, the lower port of the central tube 12 is lower than the inlet 101, the upper port of the central tube 12 is the outlet 102, and the upper port and the lower port are communicated through the inner cavity of the central tube 12, so that the dust-containing air entering from the inlet 101 cannot directly enter the outlet 102 without rotation, thereby improving the dust removal effect.
[0061] AsFigure 2 , Figure 4 and Figure 5 As shown, a waste discharge port 103 is provided at the bottom of the housing 1. The dust removal device 100 also includes a one-way valve 14, which is installed at the waste discharge port 103 with its inlet facing the cyclone chamber 11. When the one-way valve 14 is open, the cyclone chamber 11 is unidirectionally connected to the outside through the waste discharge port 103. The waste discharge port 103 is used to discharge dust particles accumulated at the bottom of the housing 1. The one-way valve 14 installed at the waste discharge port 103 facilitates the opening and discharge of waste. When waste discharge is not required, the one-way valve 14 keeps the waste discharge port 103 closed to prevent dust particles from entering the water tank from the waste discharge port 103. The one-way valve 14 can be an automatically controlled one-way valve or a manually controlled one-way valve.
[0062] In one embodiment, the one-way valve 14 includes a valve plate and an elastic element. The valve plate is hinged to the housing 1 and closes the exhaust port 103 from the outside inward. The elastic element applies a force that causes the valve plate to abut against the housing 1. The one-way valve 14, composed of the valve plate and the elastic element, facilitates automatic opening and closing. When the water tank is being filled, the gas inside the water tank flows into the cyclone chamber 11 through the inlet and outlet ports, increasing the air pressure in the cyclone chamber 11. This increases the pressure, overcoming the elastic force of the elastic element, causing the valve plate to open outward, allowing dust particles accumulated at the bottom of the housing 1 to be discharged through the exhaust port 103. When the water tank is being pumped out, external gas flows into the receiving cavity through the inlet 101 and the cyclone chamber 11. Under the force of the elastic element, the valve plate closes the exhaust port 103.
[0063] Of course, in other embodiments, the check valve may also adopt other structures.
[0064] like Figure 4 As shown, the cyclone chamber 11 includes a cylindrical chamber 111 and a conical chamber 112 connected to each other. The conical chamber 112 is located at the lower part of the cylindrical chamber 111, which improves the cyclone effect of the cyclone chamber 11 and also makes it easier for the separated dust particles to accumulate at the bottom of the cylindrical chamber 111, making it easier to remove dust particles.
[0065] like Figure 5 As shown, the dust removal device 100 also includes a filter element 2, which is installed at the inlet 101. The filter element 2 is used to filter dust entering the inlet 101, thereby improving the cleanliness of the air. Preferably, the filter element 2 is PP cotton.
[0066] like Figures 1-5As shown, the dust removal device 100 also includes a housing 3, within which the dust removal device 100 is housed. A louver 31 is provided on the side of the housing 3, corresponding to the inlet 101. The filter element 2 is installed on the housing 3 and covers the louver 31. The louver 31 increases the area of the inlet 101, facilitating air intake or exhaust. The housing 3 forms a protective shell, protecting the dust removal device 100 and also ensuring a neat appearance for the dust removal device 100.
[0067] In this embodiment, multiple dust removal devices 100 are provided. The outlets of the multiple dust removal devices 100 are connected in parallel through pipes. The inlets of the multiple dust removal devices 100 are all corresponding to the louvers 31 of the outer casing 3 to improve the dust removal effect.
[0068] This embodiment also discloses a water purifier, which includes a water tank as described above.
[0069] Example 2
[0070] like Figures 6-10 As shown, this embodiment is basically the same as embodiment 1, except that the dust removal device 100 also includes a dehumidification device 4, which includes a condenser plate 41 and an electronic refrigeration module 42. The condenser plate 41 is connected to the electronic refrigeration module 42 and is located in the passage between the filter element 2 and the inlet. A drain outlet 104 is also provided at the lower end of the outer casing 3, corresponding to the condenser plate 41. The drain outlet 104 is used to drain the condensate generated on the condenser plate 41. When the electronic refrigeration module 42 is powered on, the condenser plate 41 cools, condensing and dehumidifying the air flowing through it, keeping the air entering or exiting the water tank dry and clean. This also keeps the internal components of the dust removal device 100 in a dry environment, preventing bacterial growth and extending the service life of the dust removal device 100. A one-way valve (not shown in the figure) is installed at the drain outlet 104, with the outlet facing outwards. When condensate needs to be drained, the one-way valve is opened; when drainage is not required, the one-way valve closes the drain outlet 104 to prevent dust from entering the outer casing 3. The cooling principle of the electronic cooling module is existing technology.
[0071] Example 3
[0072] This embodiment is basically the same as Embodiment 1, except that the dust removal device also includes a heating device, which consists of a heating element and an electronic heating module. The heating element is connected to the electronic heating module and is positioned close to the filter element. When the electronic heating module is powered on, the heating element generates heat, which heats the filter element, keeping it dry, preventing bacterial growth, and improving the filtration effect. The heating principle of the electronic heating module is existing technology.
