In the following description, different "one embodiment" or "an embodiment" refers to not necessarily the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

The utility model discloses an air purification and disinfection device which can be independently used without depending on an air outlet, can provide reliable and efficient air purification and sterilization and disinfection treatment, has a simple structure, a small and exquisite appearance and a good implementation prospect, and can be suitable for respective application scenes.

First embodiment

As shown in fig. 1 and fig. 2, the air purification and disinfection apparatus 100 specifically includes at least one plasma generator 2, a bracket 1 and a fan apparatus 4, where the bracket 1 includes a bracket body 10, an electrical unit 19 disposed on the bracket body 10, and at least one set of mounting arms 12 extending from the bracket body 10, and the plasma generator 2 is detachably mounted between the set of mounting arms 12; the fan device 4 is disposed on one side of the plasma generator 2 to generate an air flow toward the plasma generator 2, and the plasma generator 2 and the fan device 4 are electrically connected to the electrical unit 19, respectively.

According to the utility model, the fan device 4 is configured for the plasma generator 2, so that the plasma generator 2 does not need to be arranged at various air outlets for use, and can independently work to form an independent product for purifying and sterilizing air. Specifically, the plasma generator 2 and the fan device 4 are powered by the electrical unit 19, and when the airflow generated by the operation of the fan device 4 blows over the surface of the plasma generator 2, a large amount of positive and negative ions generated on the surface of the plasma generator 2 are taken away, so that the positive and negative ions are rapidly scattered in the ambient air, and the ambient air is sterilized and disinfected by the positive and negative ions.

The electric unit 19 at least includes a power supply and a high voltage transformer for boosting the power supply output by the power supply to a required high voltage to form a high voltage electric field, and the high voltage transformer is electrically connected to the plasma generator 2. The power supply is a storage battery or an external power supply.

The plasma generator 2 has various structures. Generally speaking, the plasma generator 2 includes one or more dielectric barrier discharge units, each of which includes an emission pole plate, a ground pole plate and a dielectric barrier plate disposed between the emission pole plate and the ground pole plate, the emission pole plate and the ground pole plate are electrically connected to two poles of the high voltage transformer of the electrical unit 19, respectively, so that a high voltage electric field is formed between the emission pole plate and the ground pole plate, and the dielectric barrier plate forms dielectric barrier discharge in the high voltage electric field, so as to ionize air to form positive and negative ions. The dielectric barrier discharge unit has the characteristics of compact structure, convenience in installation and good disinfection effect.

The mounting arm 12 is located at a side of the bracket body 10. Since the size of the bracket body 10 tends to be small to facilitate the overall miniaturization of the air cleaning and sterilizing apparatus, the size of the plasma generator 2 may be larger than the size of the bracket body 10. For this, the side of the bracket body 10 is provided with an extension arm 11, and the mounting arms 12 are provided at the end of each of the extension arms 11, so that the interval between two adjacent mounting arms 12 matches the length of the plasma generator 2.

For example, the mounting arm 12 includes a mounting groove, and the tip of the plasma generator 2 is inserted into the mounting groove of the mounting arm 12, thereby making the plasma generator 2 easy to detach and mount. Meanwhile, the bracket 1 may be provided with a plurality of sets of mounting arms 12, and a plurality of plasma generators 2 are mounted on the bracket 1, so that the plasma generators 2 work simultaneously, which is beneficial to enhancing the effects of purification, sterilization and disinfection of ambient air.

In one embodiment, a display lamp assembly 3 is further disposed on an outer side surface of the bracket body 10, the display lamp assembly 3 is electrically connected to the electrical unit 19, and the display lamp assembly 3 is used for displaying whether the air purification and disinfection state is in an operating state or a shutdown state. For example, an electrical jack 101 electrically connected to the electrical unit 19 is disposed on the outer side of the bracket body 10, a socket 31 is correspondingly disposed on the display lamp assembly 3, and the display lamp assembly 3 can be mounted on the outer side of the bracket body 10 by inserting the socket 31 into the electrical jack 101, so that the mounting operation is simple.

The number of the fan units 4 is one or more, and when a plurality of the fan units 4 are used in combination, the plurality of the fan units 4 are arranged side by side. The fan device 4 is preferably an axial fan having a strong wind force. This is because the rotation direction of the axial flow fan is the same as the direction of rotation when the axial flow fan is subjected to external wind, so that when the present invention is used in the air duct 8 of the air conditioner as shown in fig. 5 to 7, the axial flow fan itself is electrified to operate when the air conditioner is turned on, and the blown wind is larger. The self-rotation direction of the cross flow fan is opposite to the blowing direction of the air conditioner, so the cross flow fan cannot be used in the structure.

In a preferred embodiment, the air purifying and sterilizing device further comprises a fan housing 5, and a plurality of air inlets 51 are arranged on the fan housing 5. The fan cover 5 is fixedly connected with the bracket 1 through any one of the existing fixing structures such as screws and buckles, the fan device 4 is positioned between the fan cover 5 and the bracket 1, and the fan device 4 is pressed and fixed on one side surface of the bracket 1 by the fan cover 5.

Second embodiment

As shown in fig. 3-7. The second embodiment differs from the first embodiment mainly in that: the profile of the bracket 1 is different so that the position of the mounting arm 12 is different. Specifically, at least one receiving through-groove 102 is formed in the bracket body 10, and the mounting arms 12 are oppositely disposed on two opposite groove walls of the receiving through-groove 102, so that the plasma generator 2 is mounted in the receiving through-groove 102.

The utility model can be used independently, and can be placed at an air outlet. As shown in fig. 5 to 7, the present invention is used by being placed in an air duct 8 of an air conditioner. Generally, the air outlet grid 9 is arranged at the end of the air duct 8 to enclose the air purifying and sterilizing device of the present invention in the air duct 8.

The utility model does not depend on the condition that the air conditioner is in a starting working state, even if the air conditioner is in a non-starting state, the air outlet grid 9 is utilized to carry out air convection with the outside under the action of the fan device 4 (see figure 6), and the utility model can also provide purification, sterilization and disinfection treatment for the ambient air. Of course, as shown in fig. 7, when the air conditioner is in the on state, the air flow in the air duct 8 can accelerate the positive and negative ions on the surface of the plasma generator 2 to overflow from the air outlet grid 9, so as to prevent the positive and negative ions from gathering in the air duct 8 and being unable to be discharged in time, thereby being beneficial to improving the air purification, sterilization and disinfection treatment effect.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
