Description

Technical Field

[0001] The utility model relates to the technical field of air purification, in particular to a ceiling-mounted air purifier. Background Art

[0002] The Chinese patent "Application No. 202123263927.9" applied by the applicant earlier discloses a ceiling-mounted air purifier, which adopts a suspension rod in conjunction with an arched hanger to realize the lifting of the product. In this suspension rod installation structure, the suspension rod is pre-made in the factory, and the length cannot be adjusted after it is made, which makes it difficult to adapt to different lifting height requirements. In addition, the Chinese patent "Application No. 202123266597.9" applied by the applicant earlier discloses a new type of ceiling-mounted air purifier, and a plasma sheet is also provided in the upper part of the shell. There are deficiencies in the installation position of this plasma sheet: 1. When the plasma generated by the plasma sheet needs to be sent from the upper part of the shell to the lower part, and then sent out from the air outlet at the bottom, the delivery path of the plasma in the shell is long, which is not conducive to efficient delivery. 2. Once the plasma sheet is damaged, the lower part of the shell needs to be completely disassembled for repair. This disassembly and assembly operation is cumbersome and very inconvenient. Therefore, it is necessary to improve. Summary of the invention

The fan 2 is arranged below the air duct and between the air outlet cavity 12 through a fan housing seat 21. The negative ion emission head 3 is arranged in the outer shell 1, and it is directly opposite to the negative ion emission hole.

[0028] Specific reference Figures 3 to 5 The cylindrical inner shell 4 is arranged in the middle and upper part of the outer shell 1, and its bottom end has an upwardly arched hanging seat portion 41, the middle part of the hanging seat portion 41 has a hanging plate portion and 2 to 4 oblique support plate portions 42 arranged at intervals around the hanging plate portion, the middle part of the hanging plate portion has a hanging seat hole 43, the lower end of the oblique support plate portion 42 is connected to the cylindrical inner shell 4, the hanging seat portion 41 extends upward to the upper part of the cylindrical inner shell 4, and the top of the outer shell 1 has a shell seat hole arranged opposite to the hanging seat hole 43; a hanging rope 5 passes through the hanging seat hole 43 and the shell seat hole in turn, and is fixedly connected to the hanging seat portion 41 through a wire locker 51.

[0029] In the above structure, the upwardly arched hanging seat portion 41 is used for fixed connection between the hanging rope 5 and the air purifier. At the same time, the hanging seat portion 41 is arranged at the bottom end of the cylindrical inner shell 4 to prevent the hanging seat portion 41 from being higher than the cylindrical inner shell 4, making the cylindrical inner shell 4 shorter, and thus making it easier for the entire outer shell 1 to create a shorter visual state, so that the overall air purifier forms a shorter and thicker appearance in space, which is easy to create a heavy and atmospheric visual experience.

[0030] Specific reference Figure 3 Furthermore, a plasma sheet 6 with a rectangular sheet structure is provided in the air outlet cavity 12.

[0031] In the above structure, the plasma sheet 6 is arranged in the air outlet cavity 12 at the bottom of the housing 1. After the plasma sheet 6 generates plasma, it is immediately forced out through the air outlet hole 13 at the bottom through the fan 2. The plasma has a short delivery path in the housing 1 and can be efficiently and quickly output to the environment. Secondly, once the plasma sheet 6 is damaged, it can be repaired or replaced by simply disassembling the bottom of the housing 1. This disassembly and assembly operation is simple and convenient. It should be pointed out that in this embodiment, the bottom of the housing 1 is set as a detachable shell cover 103, and the air outlet cavity 12 is set above the shell cover 103. In this way, the plasma sheet 6 can be quickly and efficiently repaired by opening the shell cover 103 at the bottom.

[0033] Specific reference Figure 1 Further, the air outlet holes 13 include a plurality of air outlet holes 13 and are distributed in a circular array, and the plasma sheet 6 includes a plurality of air outlet holes 13 and is distributed vertically at intervals. In the above structure, the air outlet holes 13 distributed in a circular array ensure air supply efficiency and air supply uniformity.

[0034] Specific reference Figure 1 and Figure 3 Further, the negative ion emission holes include a plurality of holes and are distributed in a circular array along the inner side of the air outlet hole 13, and the negative ion emission heads 3 include a plurality of holes and are directly opposite to the negative ion emission holes. A release beam 31 is provided at the end of the negative ion emission head 3, and the release beam 31 passes through the negative ion emission hole. A cleaning member 7 is provided near the release beam 31, and the cleaning member 7 has a vertical axis 71 and a plurality of cleaning heads 72 horizontally arranged with the vertical axis 71 as the center. The vertical axis 71 is arranged in the center of the circular array corresponding to the negative ion emission holes. A motor 73 is also provided in the air outlet cavity 12, and the end of the vertical axis 71 penetrates into the housing 1 and is connected to the output shaft of the motor 73. The output shaft of the motor 73 can drive the cleaning member 7 to rotate, so that the cleaning head 72 can sweep over the release beam 31 while rotating.

[0035] In the above structure, the negative ion emission holes and the negative ion emission head 3 distributed in a circular array ensure that the negative ions generated are efficient and uniform, and the release beam 31 at the end of the negative ion emission head 3 is swept by the cleaning member 7 to clean the release beam 31, thereby ensuring that the negative ions are efficiently released from the release beam 31.

[0036] Specific reference Figure 3 , Figure 4 and Figure 6 Furthermore, a lower inner shell 45 is fixedly installed below the cylindrical inner shell 4 in the outer shell 1, and the air outlet cavity 12 is arranged in the lower inner shell 45. The lower inner shell 45 is a cylindrical structure, and a motor mounting seat 46 is provided in the middle thereof. The side of the motor mounting seat 46 has 2 to 4 support bars 47 arranged at intervals, and the ends of the support bars 47 are connected to the inner wall of the lower inner shell 45. The motor 73 is fixedly installed on the motor mounting seat 46.

[0037] In the above structure, the air outlet cavity 12 which can be neatly connected with the air outlet end of the fan 2 is formed by the lower inner shell 45, and a motor mounting seat 46 is arranged in the lower inner shell 45, which has the characteristics of compact structure and easy assembly.

[0038] Furthermore, the outer wall of the cylindrical inner shell 4 has an inner shell side groove 40 for installing electrical components, and the outer wall of the lower inner shell 45 has an outer wall side groove 450 for installing other electrical components. The electrical components usually include a high-voltage power supply for power supply, a negative ion generator for the negative ion emission head 3, and a plasma generator for the plasma sheet 5, etc., which further optimizes the structure of the product and facilitates the rapid assembly of the product.

[0039] When the air purifier of this embodiment is in use, it is suspended on the indoor ceiling by the suspension rope 5. During operation, driven by the fan 2, the airflow enters the air duct from the air inlet 11 of the housing 1 and then enters the air outlet cavity 12. The plasma generated by the plasma sheet 6 of the plasma generator is blown out from the air outlet 13 along with the airflow, and the negative ions generated by the negative ion emission head 3 of the negative ion generator move downward along with the airflow blown out nearby, thus creating a good and comfortable living, working and leisure environment for indoor users.
