[0023] To make the objectives, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the accompanying drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, rather than all of them. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of this application.

[0024] The terms "first", "second", etc. in the specification and claims of this application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of this application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same type, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally indicates an "or" relationship between the associated objects before and after.

[0025] Humidifiers are divided into: direct evaporation type humidifiers and ultrasonic humidifiers.

[0026] Direct evaporation type humidifiers are usually called pure type humidifiers. The pure type humidification technology is a new technology just adopted in the humidification field. The pure humidifier removes calcium and magnesium ions in water through molecular sieve evaporation technology, completely solving the problem of "white powder" inside the humidifier. At the same time, the water vapor generated by it is healthier and safer than water mist.

[0027] Ultrasonic humidifiers use ultrasonic atomizers to atomize water into ultra-fine particle water mist of 1-5 microns through high-frequency oscillation (1.7 MHZ frequency), and the water mist is diffused into the air through a fan, thereby increasing the air humidity in the room.

[0028] According to the characteristics of ultrasonic humidifiers, during the process of atomizing water into water mist, harmful substances in the water will also be adsorbed in the water mist, which will affect human health when inhaled into the human body.

[0029] In view of the above problems existing in ultrasonic humidifiers, the embodiments of the present application provide a humidifier water and gas purification device, which can purify the water mist generated by the ultrasonic humidifier and then diffuse it into the air, thereby avoiding the impact of harmful substances in the water mist on the health of users.

[0030] The following will combine the accompanying drawings and explain in detail the humidifier water and gas purification device provided by the embodiments of the present application through specific embodiments and their application scenarios.

[0031] As Figure 1 shown, a schematic structural diagram of a humidifier water and gas purification device provided by an embodiment of the present application. The humidifier water and gas purification device is installed at the exhaust port of the humidifier 1. The humidifier water and gas purification device includes: a cylindrical lower housing 2 and a conical upper housing 3.

[0032] As Figure 2 shown, it is another schematic structural diagram of the humidifier water and gas purification device provided by an embodiment of the present application. The lower housing 2 is provided with a purification chamber 201. A detachable porous medium is installed in the purification chamber 201. An air inlet hole is provided on the housing of the purification chamber 201. A motor 301 and a centrifugal fan 302 are provided at the top of the upper housing 3.

[0033] Exemplarily, the motor 301 is used to drive the centrifugal fan 302 to rotate. The water mist generated by the humidifier 1 enters the purification chamber 201 through the air inlet hole under the action of the centrifugal fan 302, is filtered by the porous medium and then enters the upper housing 3, and is discharged through the top of the upper housing 3.

[0034] Exemplarily, one end of the upper housing 3 close to the centrifugal fan 302 is narrower, and the end far from the centrifugal fan 302 is wider.

[0035] In this way, through the humidifier water mist purification device installed on the humidifier, the water mist generated by the humidifier can be purified and then diffused into the air, avoiding the impact on the health of users due to water quality problems or the humidifier not being cleaned for a long time.

[0036] Optionally, in the embodiments of the present application, a circular opening is provided at the top of the purification chamber 201. The circular opening is used for replacing the porous medium.

[0037] Exemplarily, as Figure 3 shown in the schematic structural diagram of the lower housing, a circular opening is provided at the top of the purification chamber 201. This circular opening can not only facilitate the centrifugal fan 302 to suck the purified water mist in the purification chamber into the upper housing, but also be used for replacing the porous medium 204.

[0038] It should be noted that the above-mentioned porous medium 204 is used to purify the water mist generated by the humidifier. It consists of a skeleton made of solid substances and a substance composed of a large number of tiny voids densely grouped and separated by the skeleton. The fluid in the porous medium 204 moves in a seepage manner. The main physical characteristics of the porous medium are that the void size is extremely small and the specific surface area value is very large. The tiny voids in the porous medium may be interconnected or partially connected and partially unconnected.

[0039] Exemplarily, as Figure 3 shown in the schematic diagram of the lower housing structure, a cylindrical fixing device 202 is provided at the bottom of the purification chamber 201 of the purification chamber. The cylindrical fixing device 202 is used to fix the porous medium.

[0040] It can be understood that, usually, the filter element of the purification device is cylindrical and has a cavity inside. Therefore, a cylindrical fixing device can be provided at the bottom of the purification chamber 201 to fix the filter element (i.e., the above-mentioned porous medium) used in the humidifier purification device.

[0041] Optionally, in the embodiments of the present application, in order to facilitate the disassembly and assembly of the upper and lower housings when the user replaces the filter element (i.e., the above-mentioned porous medium), the humidifier water and gas purification device provided in the embodiments of the present application is further provided with a quick-release device.

[0042] Exemplarily, as Figure 3 shown in the schematic diagram of the lower housing structure, a positioning hole 203 is provided at the top of the lower housing 2.

[0043] Exemplarily, as Figure 4 shown in the schematic diagram of the upper housing structure, a positioning post 303 corresponding to the position of the positioning hole 203 is provided at the bottom of the upper housing 3. The positioning hole 203 and the positioning post 303 are used to connect the upper housing 3 and the lower housing 2.

[0044] Exemplarily, since a certain air pressure difference is required inside and outside the purification chamber to make the water mist generated by the humidifier be sucked into the purification chamber, therefore, in order to make the centrifugal fan 302 of the upper housing 3 generate a sufficient pressure difference inside and outside the purification chamber, the upper housing 3 is designed as a conical shape. And the diameter of the bottom of the upper housing 3 is larger than the diameter of the top of the upper housing.

[0045] It can be understood that when the gas flows through the conical upper housing, there is a vacuum at the contraction section inside the conical upper housing, which improves the flow capacity of the upper housing, and the jet velocity of the gas is also greater, thereby increasing the air pressure difference inside and outside the purification chamber. Making the water mist generated by the humidifier more easily pass through the porous medium.

[0046] Optionally, in the embodiments of the present application, since the water mist generated by the humidifier is liquid small water droplets, after the water mist contacts the upper and lower shells, it will adhere to the inner wall of the shell. In order to avoid excessive water stains on the inner wall of the shell, a diversion device needs to be involved.

[0047] Exemplarily, as Figure 2 shown in the structural schematic diagram of the water mist purification device of the humidifier, a water guide groove 204 that curls inwards is provided at the bottom of the inner wall of the lower shell 2. The water guide groove 204 is used to guide the residual water stains on the inner wall of the lower shell into the humidifier.

[0048] Exemplarily, as Figure 2 shown in the structural schematic diagram of the water mist purification device of the humidifier, a water guide groove that curls outwards is provided at the bottom of the outer wall of the purification chamber 201. The water guide groove is used to guide the residual water stains on the outer wall of the purification chamber into the humidifier.

[0049] It should be noted that since the water stains on the inner part of the upper shell 3 of the humidifier water mist purification device can directly flow into the lower shell 2 through the connection with the lower shell 2, the upper shell 3 does not need to be provided with a diversion groove. The opening position of the diversion groove on the lower shell 2 can be set according to the position of the exhaust port of the humidifier.

[0050] Exemplarily, considering the power supply of the above-mentioned humidifier water purification device, in the embodiments of the present application, a first contact is provided at the bottom of the upper shell; a second contact that contacts the first contact is provided at the top of the lower shell; a third contact that contacts the humidifier is provided at the bottom of the lower shell; the first contact, the second contact, and the third contact are used to supply power to the motor.

[0051] Exemplarily, the above-mentioned first contact is connected to the motor, and the second contact is connected to the electrical three contacts. The third contact supplies power and control to the motor of the upper shell by contacting the corresponding contact on the humidifier.

[0052] For the humidifier water purification device provided in the embodiments of the present application, the water mist generated by the humidifier is first inhaled into the purification chamber of the humidifier purification device for purification, and then the purified water mist is diffused into the air to avoid the impact on the user's health caused by water quality problems or the humidifier not being cleaned for a long time.

[0053] The embodiments of the present application also provide a humidifier, and a humidifier water purification device as provided in the embodiments of the present application is installed at the exhaust port of the humidifier.

[0054] The embodiments of the present application also provide an air purifier, which has a structural design such as the above-mentioned humidifier water purification device.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
