Description

A ceiling type air purifier

technical field

The utility model relates to an air purifier, in particular to a suspended ceiling air purifier.

Background technique

Air purifiers have the functions of filtering dust, eliminating odors and harmful gases, double sterilization, and releasing negative ions. It circulates the indoor air through the motor, and the polluted air passes through the air filter inside the machine to remove or absorb various pollutants, and then passes through the negative ion generator installed at the air outlet to continuously ionize the air and generate a large amount of negative ions. It is sent out by the breeze to form a negative ion airflow to achieve the purpose of cleaning and purifying the air. Because indoor formaldehyde and other harmful gases often exceed the standard in home decoration, many families are willing to buy an air purifier, especially as the heating season is approaching, since indoor doors and windows will be closed frequently in the future, air purifiers are even more important. Became the darling of the market.

Most of the current purifiers place the purifier in the use space and occupy a limited space. However, most of the current houses have a suspended ceiling, and the space on the suspended ceiling is basically not used, so there is a lot of usable space. Technicians in the industry have developed some ceiling-mounted air purifiers. For example, the patent document with the authorized announcement number CN 202129025 U discloses a ceiling-mounted air purifier, which includes a housing, a purification device, a fan , control device, described purification device, blower fan, control device are arranged in the inside of casing, blower fan is connected with purification device, and described control device is connected with blower fan and purification device respectively; Described purification device comprises high-voltage electric field module , discharge needle, adsorption filter, photocatalytic filter, ultraviolet lamp, primary filter; the shell includes a bottom shell, an upper shell, a connecting flange, a cover plate, lifting lugs, a shunt cover, and an air outlet. Although this type of ceiling-mounted air purifier can effectively purify the air, the air outlet is directly arranged on the distribution cover, and when the air flows out from the air outlet, it will undoubtedly hit the distribution cover, the air flow is not smooth, and it is easy to cause energy loss .

Because there are many engineering constructions such as road construction and site construction in the city at present, and the dust in the air is relatively large, technicians in the industry have also developed some air cleaners with dust collection functions, such as the application publication number CN 1223174 A The application document discloses an electronic dust-collecting air purifier. The air purifier is mainly provided with a dust-collecting device at the input end of a high-voltage negative ion generator. Stacked, the containing tray is respectively provided with a filter layer wound by a plurality of crimped flat and thin metal wires, so that the dust collecting device passes through the metal filter layer spaced apart from each other to generate The charge induction of the negative ion generator continuously supplies the electrons required for the output discharge of the negative ion generator, and forms the effect of electrostatic dust collection and negative ion generation with the dust collecting device and the air respectively, so that the air purifier can output negative ions, However, although the air purifier will not cause flashover due to excessive accumulation of dust particles on the dust collection plate and cause leakage, the grounding of the dust collection device of the air purifier The connection between the terminal and the ground wire may not be firm, so that the air purifier may still have the risk of electric leakage.

For this reason, need a kind of novel ceiling type air cleaner.

Utility model content

The purpose of the utility model is to provide an air purifier with smooth air flow, low energy loss, convenient maintenance, reliable grounding of the dust collecting device and no risk of electric leakage.

In order to achieve the above object, the utility model adopts the following technical solutions:

A ceiling-type air purifier, including a box body, a purification device and an electric control box are arranged in the box body, and the two sides of the box body are respectively connected with an air intake pipe and an exhaust pipe, and the purification device includes an electrostatic dust collection box, especially , the box is provided with at least two elastic buckles connected with the box; the elastic buckle is provided with a flange part connected with the electrostatic dust collection box; the air intake pipe and the exhaust pipe are connected with the box body There is a reduced-diameter pipeline; the reduced-diameter pipeline includes a first connection part connected to the box body and a second connection part connected to the intake pipe or exhaust pipe; the first connection part is provided with a connection for connecting the box body and the variable-diameter pipeline Connection hole; the second connection part is provided with an installation hole for installing the intake pipe or the exhaust pipe; an arc surface for reducing the local resistance of the pipe is provided between the first connection part and the second connection part.

The box body and the elastic buckle are preferably made of metal.

Principle of the present utility model is as follows:

The electrostatic dust collection box is installed between the elastic buckles and connected with the flange of the elastic buckles. Because the elastic buckle is connected with the box body, when the box body is installed on the wall, the electrostatic dust collection box will be grounded, and the elasticity of the elastic buckle itself will ensure that the electrostatic dust collection box is always connected with the elastic buckle, thereby ensuring the static electricity The dust box is always grounded. Even if the air purifier shakes during operation, the electrostatic precipitator will not disengage from the elastic buckle, thereby preventing leakage.

Compared with the current grounding method that installs the electrostatic dust collection box in the slideway in the box and connects the ground terminal through the ground wire, the connection between the elastic buckle and the electrostatic dust collection box is more reliable, and the elastic energy of the elastic buckle itself is effective. Ensure that the electrostatic dust collection box is always connected to the box body. After the user installs the box with fasteners such as suspenders or bolts, the electrostatic dust collection box can be grounded through the connection between the box and the fasteners, and this grounding method has no risk of breaking the ground wire, and the electrostatic dust collection box leaks electricity. chances are greatly reduced.

Since the purification device is installed in the box, in order to facilitate the installation of the purification device, the box body is generally in a square structure, while the air intake pipe and exhaust pipe are generally in a circular structure, and the cross-sectional area of the box body is generally larger than that of the air intake pipe and exhaust pipe. The cross-sectional area of the air duct, when the air flows from the box to the exhaust duct, part of the air will often hit the inner wall of the box, resulting in energy loss. By installing variable-diameter pipes between the intake pipe, exhaust pipe and the box, when the air flows from the box to the side of the exhaust pipe, it will naturally flow into the exhaust pipe through the arc surface of the variable-diameter pipe, and the energy Losses are greatly reduced.

The purification device of the air purifier can also include activated carbon filter screen, ozone adsorption net, nano photocatalyst net, ultraviolet lamp, HEPA filter screen and primary effect filter screen, primary effect filter screen, HEPA filter screen, electrostatic dust collection box, ultraviolet lamp , nano photocatalyst net, ozone adsorption net, and activated carbon filter net are arranged in sequence along the direction of air flow. After the air enters the box from the intake pipe, it will pass through the primary filter, HEPA filter, electrostatic dust collection box, ultraviolet lamp, nano photocatalyst net, ozone adsorption net, and activated carbon filter in order to be fully purified.

A negative ion generator can also be installed on the electric control box, and the output end of the negative ion generator is in the downstream of the active carbon filter screen. After the air is filtered seven times by the primary filter, HEPA filter, electrostatic dust collection box, ultraviolet lamp, nano-photocatalyst net, ozone adsorption net, and activated carbon filter, the negative ions generated by the negative ion generator are supplemented to further improve the quality of the air.

In order to facilitate installation, the primary filter, HEPA filter, electrostatic dust collection box, ultraviolet lamp, nano photocatalyst net, ozone adsorption net, and activated carbon filter are generally installed in the slideway in the box and can slide relative to the box. In order to facilitate the replacement of the filter screen, the box body is preferably provided with a maintenance cover that can be detachably opened on the box body, and the electric control box is installed on the maintenance cover. When the air purifier needs maintenance, the maintenance cover can be removed directly, so that the primary filter, HEPA filter, electrostatic dust collection box, ultraviolet lamp, nano photocatalyst net, ozone adsorption net and activated carbon filter installed in the box are all It can be taken out directly, and the maintenance cover will not cause obstruction, which is convenient for maintenance personnel to operate.

The utility model has a simple structure, and the elastic buckle installed in the box effectively ensures the reliability of the grounding of the electrostatic dust collection box. Even if the air purifier shakes during the working process, the electrostatic dust collector will not be separated from the elastic buckle. , so as to prevent leakage; the variable-diameter pipe connecting the box with the intake pipe and exhaust pipe can make the air flow more smoothly and reduce energy loss; the maintenance cover on the box can make the replacement of the filter more convenient, and maintenance personnel The operation is simpler.

A maintenance cover 19 is installed on one side of the opening of the box body 1 , and the electric control box is installed in the maintenance cover 19 . The electronic control box is provided with high-voltage power supply 25, transformer 26, high-voltage contact plate 27 and other electronic components for starting the electrostatic dust collection box 14. An anion support 20 is also installed on the maintenance cover plate 19, and an anion probe 21 is installed on the anion support 20. After the maintenance cover plate 19 is installed and fixed on the casing 1 by bolts, the negative ion probe 21 is between the active carbon filter screen 18 and the exhaust pipe 6 .

As shown in FIG. 4 , there are two elastic buckles 22 inside the box body 1 . The elastic buckle 22 is installed in the second installation area 10 and connected with the baffle plate 8 of the second installation area 10 . A flange portion 23 is disposed on the elastic buckle 22 . When the electrostatic dust collection box 14 is installed in the second installation area 10 , the flange portion 23 on the elastic buckle 22 is in contact with the electrostatic dust collection box 14 . Due to the elasticity of the elastic buckle 22 itself, the flange part 23 will always keep in contact with the electrostatic dust collection box 14.
