[0002] A desktop air negative ion therapy device is an air purification device placed on furniture such as a desktop or a cabinet. Its main structure usually includes a housing, a fan and a negative ion generator arranged in the housing. The negative ion generator is used to generate high-concentration negative ions. The negative ions are released into the environment by the release beam at the end of the negative ion emission head to purify the ambient air and improve the quality of the ambient air. Since the release beam is arranged near the air outlet, it is very easy to accumulate dust and seriously affect the negative ion release effect. Therefore, those skilled in the art have designed a cleaning structure to regularly clean the release beam. For example, a Chinese patent with application number 202220911930.2 discloses a self-cleaning negative ion generator, in which a cleaning component is arranged, including a driving member and a cleaning member. The cleaning member is arranged on the side of the release beam, and the driving member can drive the cleaning member to sweep across the release beam, and then the release beam of the negative ion releaser is cleaned by the cleaning member. Currently, the self-cleaning component structures of negative ion generators are diverse, and air negative ion therapeutic devices with different shapes and different usage methods will adopt different self-cleaning structures.

[0020] The utility model will be further described below in conjunction with the accompanying drawings.

[0021] Example

[0022] refer to Figures 1 to 4 A negative ion emitting head cleaning mechanism of an air negative ion therapeutic device includes a mounting rod 5, a driving assembly, a negative ion emitting head 500 and a cleaning head 501 arranged near the negative ion emitting head 500.

[0023] A release beam 53 is provided at the end of the negative ion emitter head 500; the mounting rod 5 is a long rod-shaped structure, and a mounting column 51 is provided on the side of the mounting rod 5, and a columnar through hole is provided in the mounting column 51, and the negative ion emitter head 500 is installed in the columnar through hole; the driving component includes a progressive motor 7, a main gear 71 and a slave gear 72, the output shaft 70 of the progressive motor 7 is arranged in parallel with the mounting rod 5, the main gear 71 is coaxially mounted on the output shaft 70 of the progressive motor 7, the slave gear 72 is coaxially mounted on the mounting rod 5, and the main gear 71 is externally meshed with the slave gear 72, the output shaft 70 of the progressive motor 7 can drive the slave gear 72 to rotate through the main gear 71, and then drive the mounting rod 5 and the negative ion emitter head 500 to rotate synchronously, so that the release beam 53 of the negative ion emitter head 500 sweeps over the cleaning head 501.

[0024] In the above structure, the above cleaning mechanism is arranged through a mounting shell 4, specifically: Figure 3 and Figure 4 The mounting shell 4 has a mounting cavity 40, the negative ion emission head 500 is arranged in the mounting cavity 40, the mounting rod 5 is movably installed between the two sides of the mounting shell 4, the progressive motor 7, the main gear 71 and the slave gear 72 of the driving assembly are respectively installed outside the mounting shell 4, the cleaning head 501 is a sheet structure, which is vertically arranged at the bottom of the mounting shell 4, the two ends of the mounting rod 5 respectively pass through the mounting shell 4, and one end is coaxially installed with the slave gear 72.

[0025] In the above structure, specific reference is made to Figure 3 and Figure 4 After the progressive motor 7 is running, the output shaft 70 of the progressive motor 7 rotates, driving the main gear 71 and the slave gear 72 to rotate synchronously, thereby driving the mounting rod 5 and the negative ion emission head 500 to rotate. Figure 4 , so that the release beam 53 of the negative ion emitter 500 sweeps over the cleaning head 501, cleans the release beam 11, ensures its efficient and stable release of negative ions, and finally ensures that the negative ion emitter 500 releases negative ions efficiently and stably, achieving the technical purpose of purifying ambient air and improving ambient air quality. The daily state of the negative ion emitter 500 corresponds to being located near the middle of the mounting shell 4. At the same time, the running state of the progressive motor 7 is preset, such as running once every 12 hours, each time it rotates downward 100° to sweep over the cleaning head 501 and then reversely rotates and resets to the middle of the mounting shell 4. Of course, the running state of the above-mentioned progressive motor 7 can be adjusted according to the actual use environment. In addition, it should be pointed out that under the reciprocating rotation of the progressive motor 7 at a relatively small angle, the electrical connection line connecting the negative ion emitter 500 can be appropriately lengthened, and the rotation of the negative ion emitter 500 will not be hindered.

[0026] Furthermore, the cross section of the mounting rod 5 is U-shaped and has a mounting groove 50 connected to the columnar through hole. The mounting groove 50 is used to lay the wires connecting the negative ion emission head 500 and the negative ion high voltage power supply 81 described below.

[0027] Furthermore, the mounting posts 51 include a plurality of mounting posts 51 which are spaced apart on the mounting rod 5 , and the negative ion emitter heads 500 include a plurality of mounting posts 51 which are mounted one by one in the mounting posts 51 . The mounting of a plurality of negative ion emitter heads 500 is achieved through the plurality of mounting posts 51 .

[0028] Further, if Figure 2 The two ends of the side of the mounting rod 5 also have two plug posts 52, and two rotatable sleeves 401 are symmetrically provided on the inner walls of both sides of the mounting shell 4. The outer end of the sleeve 401 is installed with the gear 72, and the inner end has a protrusion 41, and the protrusion 41 has a positioning hole 42. The two plug posts 52 of the mounting rod 5 are respectively inserted into the positioning holes 42 of the two protrusions 41, so that the two ends of the mounting rod 5 can be detachably mounted on the sleeve 401.

[0029] In the above structure, the negative ion emitter head 500 is detachably mounted by the mounting rod 5, and the mounting rod 5 is rotatably mounted in the mounting shell 4 by the shaft sleeve 401, which has the characteristics of simple structure and convenient installation. When disassembly is required, the mounting rod 5 together with the negative ion emitter head 500 is lifted up, and the plug 52 of the mounting rod 5 is separated from the positioning hole 42.

[0030] Furthermore, the main gear 71 is a fan-shaped structure. Since the main gear 71 only needs to reciprocate at a relatively small angle along with the stepping motor 7, the fan-shaped structure is adopted to reduce space occupation.

[0031] When the negative ion emission head cleaning mechanism of this embodiment is applied to a negative air ion therapeutic device, a desktop negative air ion therapeutic device is used as an example. Figures 5 to 8 The negative ion emission head cleaning mechanism of this embodiment is installed in the housing 1 of the desktop air negative ion therapeutic device. The top surface of the housing 1 is detachably installed with an air inlet fence portion 11 and has an air inlet hole 110, and the front surface is detachably installed with an air outlet fence portion 12 and has an air outlet hole 120. The installation shell 4 is arranged between the air inlet fence portion 11 and the air outlet fence portion 12 in the housing 1. Figure 8 As shown, the installation cavity 40 also acts as an air duct to connect the air inlet 110 and the air outlet 120. A fan 2 is arranged in the installation cavity 40, and the negative ion emitter 500 is arranged in the installation cavity 40 and faces the air outlet fence 12.

[0032] When in use, driven by the fan 2, the airflow enters the installation cavity 40 from the air inlet 110 of the housing 1. The negative ions generated by the negative ion emitter 500 are blown out from the air outlet 120 along with the airflow blown out near it. At the same time, after a certain running time, the progressive motor 7 is powered on to drive the negative ion emitter 500 to reciprocate and sweep over the cleaning head 501, cleaning the release beam 11, ensuring its efficient and stable release of negative ions, and creating a good and comfortable living, working and leisure environment for indoor users.
