Description

Technical Field

[0001] This utility model relates to the field of air purifier filter core technology, specifically to a wire mounting structure for an ultraviolet lamp and a filter core with an ultraviolet lamp. Background Technology

[0002] The filter element of an air purifier is the core component of the device, specifically responsible for removing pollutants from the air and ensuring that the purified air is clean and healthy. It intercepts dust, pollen, bacteria, viruses, and fine particles (such as PM2.5) through physical or chemical means, preventing these impurities from entering the internal system of the purifier and completing the filtration and purification of air pollutants.

[0003] To improve sterilization, some air purifiers incorporate UV lamps within their filters. However, these UV lamps require a power supply and a power cord. The existing cords are often scattered, resulting in a messy and disorganized internal wiring system. Furthermore, since the filters need to be periodically removed and replaced, and are typically installed in a drawer-style configuration, removal involves pulling them out horizontally. The UV lamp's power cord, connected via a standard power supply, is inconvenient to disconnect during this process, causing further inconvenience. Utility Model Content

[0004] The purpose of this invention is to solve the technical problems of the messy wire arrangement of existing filter elements and the inconvenience of disassembling the filter elements due to wire connections, and to provide a wire installation structure for an ultraviolet lamp and a filter element with an ultraviolet lamp.

[0023] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0025] It should be noted that all directional indications (such as up-down-left-right-forward-backward...) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0026] like Figures 1-5 As shown, a wiring installation structure for an ultraviolet lamp includes a mounting cover body 1 installed in the middle of a filter element. The mounting cover body 1 includes a lower shroud 2 and an ultraviolet lamp 3. The lower shroud 2 includes a first mounting ring 21, an arc-shaped support piece 22, and a first center plate 23. A first through hole is opened in the middle of the first mounting ring 21. The arc-shaped support piece 22 is fixed on the first mounting ring 21 and arranged circumferentially along the first through hole. The first center plate 23 is located above the first mounting ring 21, and a lamp holder 24 is fixedly connected to the first center plate 23. The wiring terminals of the ultraviolet lamp 3 are installed in the lamp holder 24. The lamp holder 24 is connected to a power cord 4 that is electrically connected to the ultraviolet lamp 3; a guide rod 5 is installed on the lower shroud 2. The guide rod 5 is set in an arc shape that matches the arc-shaped support plate 22. The guide rod 5 is embedded between two adjacent arc-shaped support plates 22. A fixing block 6 is fixedly connected to one end of the guide rod 5 at the first mounting ring 21. The fixing block 6 is fixed on the first mounting ring 21. A power contact 71 is provided on the fixing block 6. A wire groove is provided on the upper side of the guide rod 5. The power cord 4 passes through the wire groove of the guide rod 5 and extends downward into the fixing block 6 to be electrically connected to the power contact 71.

[0027] By adopting the above technical solution, the ultraviolet lamp 3 is installed in the lamp holder 24, and the power cord 4 of the lamp holder 24 is constrained by the guide rod 5 and guided to the fixing block 6 at the lower end. The power contact 71 on the fixing block 6 is connected to the power supply of the external structure, thereby connecting the ultraviolet lamp 3 to the external power supply. At the same time, the power cord 4 is guided and constrained by the guide rod, so that the internal power cord 4 is kept neat.

[0028] Specifically, the fixing block 6 has a receiving cavity, and two sets of power connection components 7 are arranged in the receiving cavity. The power connection component 7 includes a power connection piece 72 made of electrical conductor and a sleeve 73 made of insulating material. The power connection piece 72 and the sleeve 73 are fixedly connected to the fixing block 6. The positive and negative wires inside the power cord 4 are respectively connected to the power connection piece 72 in the two sets of power connection components 7. The lower end of the sleeve 73 is provided with a second through hole. The power connection contact 71 is located inside the sleeve 73 and slides in cooperation with the sleeve 73. The power connection contact 71 is made of conductive material. A conductive spring 74 is provided inside the sleeve 73. One end of the conductive spring 74 abuts against the power connection piece 72, and the other end of the conductive spring 74 abuts against the upper end of the power connection contact 71 to pop the lower end of the power connection contact 71 out of the second through hole. In use, under the elastic force of the conductive spring 74, the lower end of the contact 71 pops out from the second through hole and abuts against the wiring terminal inside the external purifier, thereby conducting the power from the purifier to the ultraviolet lamp 3 through the contact 71, conductive spring 74, contact piece 72, and power cord 4. When the filter element is pulled out, the mounting cover body 1 is pulled out along with the filter element. The contact 71 is squeezed into the sleeve 73 when pulled out, thereby disconnecting from the power supply, which is convenient for disassembly. At the same time, it avoids the contact 71 protruding and scratching the sealing structure at the bottom of the mounting cover body 1, and makes it easy to remove the filter element and replace the filter screen.

[0029] Specifically, a locking post 25 is provided at the bottom of the first center plate 23, and a bottom cover 8 is locked onto the locking post 25. A connecting post 81 is fixedly connected to the bottom cover 8, and an upper fastening plate 82 is fixedly connected to the connecting post 81. A lower fastening plate 26 is fixedly connected to the lower end of the locking post 25. When the bottom cover 8 rotates, the upper fastening plate 82 rotates above the lower fastening plate 26, suspending the bottom cover 8 at the bottom of the first center plate 23. By rotating, the upper fastening plate 82 and the lower fastening plate 26 are fastened together, thereby suspending the bottom cover 8 at the bottom of the first center plate 23. The power cord 4 passing through the bottom of the first center plate 23 is covered inside the bottom cover 8, thus preventing the power cord 4 from being exposed.

[0030] Specifically, a rotating block 83 is fixedly connected to the bottom of the bottom cover 8. By rotating the rotating block 83, the bottom cover 8 can be easily rotated and suspended on the first center plate 23; when it is necessary to open the bottom cover 8, the rotating block 83 is rotated in the opposite direction, so that the upper fastening plate 82 is disengaged from the lower fastening plate 26, thereby removing the bottom cover 8 from the bottom of the first center plate 23.

[0031] Specifically, the mounting cover body 1 also includes an upper wind cover 9 and a lamp cover 10. The upper wind cover 9 is fixed to the upper end of the lamp cover 10, and the lower wind cover 2 is fixed to the lower end of the lamp cover 10. The lamp cover 10 is fixed to the first center plate 23 of the lower wind cover 2.

[0032] Specifically, both the upper shroud 9 and the first mounting ring 21 are fixedly connected with clips 91. The mounting shroud body 1 can be installed on the filter element through the clips 91.

[0033] In another embodiment, the present invention provides a filter element with an ultraviolet lamp, such as... Figure 6 As shown, it includes a filter cylinder 11, which is a hollow structure, and the filter cylinder 11 is equipped with the above-mentioned guide mounting structure for an ultraviolet lamp 3.

[0034] The filter cylinder 11 is provided with locking grooves 12 at its upper and lower ends. The buckle 91 is engaged with the locking grooves 12 to secure the mounting cover body 1 into the filter cylinder 11. In use, exhaust fans are provided at both the upper and lower ends of the filter cylinder 11, allowing external air to pass through the filter cylinder 11 and enter the inner cavity of the filter cylinder 11, and then flow out upwards or downwards from the inner cavity. When the air passes through the ultraviolet lamp 3 in the middle, it is sterilized by the ultraviolet light emitted by the ultraviolet lamp 3.

[0035] The parts not covered in this technical solution can be implemented using existing technologies.
