[0018] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application; obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments of the present application, which does not constitute a limitation on the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0019] Firstly, the terms possibly used in the present text are explained as follows:

[0020] The terms "include", "contain", "have", "possess" or other similar semantic descriptions should be interpreted as non-exclusive inclusion.

[0021] The contents not described in detail in the embodiments of the present application belong to the prior art known by those skilled in the art. The specific conditions not marked in the embodiments of the present application are carried out according to the conventional conditions in the art or the conditions suggested by the manufacturer. The reagents or instruments used in the embodiments of the present application are not marked with the manufacturer, which are all conventional products that can be obtained by market purchase.

[0022] The coaxial reverse double-fan-leaf air purification device of the present application comprises a shell 001, wherein the shell 001 is provided with a volute 007 inside;

[0023] The top and the bottom of the volute 007 are respectively provided with an air inlet 003, and the side is provided with an air outlet 006;

[0024] Two coaxial and counter-rotating blades 005 are provided in the volute 007. The blades 005 include a shaft 004 provided along the core of the volute 007 and a plurality of blades 009 mounted on the shaft 004.

[0025] A motor 008 is provided in the middle of the volute 007 , and the output shaft of the motor 008 is connected to the shaft 004 .

[0026] The housing 001 is provided with two identical and oppositely mounted volutes 007, and the joint of the two volutes 007 is provided with two identical and oppositely mounted motors 008;

[0027] A fan blade 005 is respectively provided in the two volutes 007. The two fan blades 005 are identical and are respectively installed on the shafts 004 of two oppositely installed motors 008.

[0028] The two volutes 007, the two motors 008 and the two fan blades 005 are on the same axis.

[0029] The rotation directions of the two fan blades 005 are opposite.

[0030] In summary, the coaxial counter-rotating dual-blade air purifier of the embodiment of the present invention is characterized by a coaxial counter-rotating dual-blade arrangement. The two blades 005 rotate in opposite directions on the same axis and at the same speed, canceling each other's torque, significantly improving efficiency by approximately 6%-15%.

[0031] In order to more clearly demonstrate the technical solutions and technical effects provided by the present invention, the embodiments of the present invention are described in detail below with reference to specific embodiments.

[0032] Example 1

[0033] like Figures 1 to 7 As shown:

[0034] In the shell 001 of the air purifying device, two identical and reverse installed volutes 007 are arranged; two identical motors 008 are installed back to back on the two reverse installed volutes 007. Two identical fan blades 005 are respectively installed on the shafts 004 of the two motors 008. When the air purifying device works, the two groups of fan blades 005 and motors 008 rotate coaxially and reversely at the same speed. The volute 007 has an air inlet 003 and two air outlets 006; two identical filter assemblies 002 are respectively arranged in front of the air inlets 003 of the two volutes 007; when the air purifying device works, air is sucked through the filter assemblies 002 and the air inlets 003 and then released from the air outlets 006 after being purified. When the air purifying device works, the rotating torques of the two groups of fan blades 005 and motors 008 are basically the same, but they act reversely on the volute 007. Since the two groups of fan blades 005 and motors 008 are installed back to back, the torques generated by them are basically offset. Therefore, the rotating energy consumption of the motor 008 is basically all applied to the fan blade 005, thereby improving the efficiency of air flow, that is, improving the efficiency of air purification.

[0035] Since the torques are basically offset, the torque borne by the shell 001 is also basically eliminated, thereby reducing the noise generated by the vibration during work.

[0036] At the same air purification efficiency, the diameter size of the double fan blade 005 device is smaller than that of the single fan blade 005, so the overall size of the air purifying device is reduced, and the material consumption of the shell 001 of the air purifying device is also reduced.

[0037] Effects of the present application:

[0038] The efficiency is significantly improved, and the increase is about 6%-15%;

[0039] The air purification efficiency is improved, and the energy efficiency ratio is reduced;

[0040] The working noise of the air purifying device is reduced;

[0041] The size of the air purifying device is reduced;

[0042] The cost and price of the air purifying device are reduced, the performance-price ratio is improved, and the sales competitiveness is higher.

[0043] The above description is merely preferred embodiments of the present application, but the protection scope of the present application is not limited thereto, and any changes or substitutions easily conceived by those skilled in the art within the technical scope disclosed by the present application should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims. The information disclosed in the background section of the present application is merely intended to deepen the understanding of the general background of the present application, and should not be regarded as acknowledging or implying in any form that the information constitutes the prior art known to those skilled in the art.
