Description

Technical Field

[0001] This application belongs to the technical field of household ozone generators, specifically a household ozone generator. Background Technology

[0002] With the continuous improvement of people's living standards and increased attention to the quality of their living environment, air purification equipment has gradually become one of the essential household appliances. Ozone generators, as a highly efficient air purification device, are increasingly favored by families due to their excellent sterilization, deodorization, and air freshening capabilities. Ozone, with the chemical formula O3, is a gas with strong oxidizing properties that can effectively kill bacteria, viruses, and mold in the air, as well as decompose odor molecules, thereby improving indoor air quality. Compared to traditional purification methods, ozone has the advantages of being fast and efficient, does not rely on chemical additives, is convenient to use, and is environmentally friendly and pollution-free.

[0003] Currently, household ozone generators primarily produce ozone through high-voltage discharge or photolysis. They are compact, easy to operate, and suitable for home use. However, with technological advancements, some problems have also arisen. To make ozone generators more compact or aesthetically pleasing, manufacturers often use a one-piece, multi-point fixing method for the casing. This method is very inconvenient for inspection and maintenance. For example, Chinese patent CN219585830U discloses a portable ozone generator. Although this technical solution does not disclose its disassembly method, it is evident from the appendix of the technical solution... Figure 4 As can be seen, it also uses a multi-point fixing method; similarly, the handheld ozone generator disclosed in Chinese patent CN2816009Y also has the above-mentioned problems.

[0004] Therefore, the technical problem to be solved by this application is to provide a household ozone generator that is easy to inspect and maintain. Utility Model Content

[0005] The purpose of this application is to provide a household ozone generator that solves the problem of inconvenient inspection and maintenance of existing household ozone generators.

[0022] 1. The first cover plate of this application is connected to the first side plate by a hinge, and the second cover plate is connected to the top of the outer shell by a sliding method. When disassembling, it is only necessary to separate the first side plate near the second cover plate from the outer shell, and the second cover plate can be detached along the length of the outer shell.

There are only two third connection holes on the upper plate. That is to say, the upper plate can be disassembled in the vertical direction by simply removing the two screws located on the upper plate, thereby removing the restriction on the second cover plate. The second cover plate can then be detached along the length of the outer shell.

[0026] 5. In this application, the circuit board is connected to the movable plate. Driven by the movable plate, the circuit board can move along the length of the outer casing, making it easy to observe the ozone generator located below the movable plate. Attached Figure Description

[0039] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0040] Example 1

[0041] refer to Figures 1-10 A household ozone generator includes a housing 1, a first cover plate 2, a second cover plate 3, an ozone generating device 4, a first side plate 5, and a circuit assembly 6. The housing 1 is open at both ends and the top along its length. The two ends of the housing 1 along its length are detachably connected to two first side plates 5 respectively. The ozone generating device 4 is connected to the inner bottom surface of the housing 1. One of the first side plates 5 has an input terminal 54 and an output terminal 55 connected to the ozone generating device 4.

[0042] The circuit assembly 6 is connected inside the housing 1 and can move along the length of the housing 1. The circuit assembly 6 is located above the ozone generator 4.

[0043] One end of the first cover plate 2 is hinged to the top of one of the first side plates 5. The first cover plate 2 can be swung and overlapped on the top of the outer shell 1. The second cover plate 3 is connected to the top of the outer shell 1. The second cover plate 3 can move along the length of the outer shell 1. The other first side plate 5 can restrict the second cover plate 3 from detaching from the outer shell 1. The second cover plate 3 restricts the swinging of the first cover plate 2 by contacting the first cover plate 2. The first cover plate 2 and the second cover plate 3 are used to close the top of the outer shell 1. The first cover plate 2 has a control panel 21.

[0044] Regarding the ozone generator 4 in this application, it is prior art. The ozone generator 4 in this embodiment can be an ozone generator 4 well known to those skilled in the art. In addition, the technical solution disclosed in Chinese Patent CN220684691U can also be referred to regarding the ozone generator 4 in this embodiment.

[0045] Regarding the circuit component 6 in this embodiment, it is implicitly understood that the circuit component 6 and the ozone generator 4 are electrically connected, and the circuit component 6 and the control panel 21 are also electrically connected. The electrical connection is in a manner well known to those skilled in the art. It is understood that the control panel 21 can send signals to the circuit component 6, which in turn transmits them to the ozone generator 4, thereby controlling the ozone generator 4. However, the connecting lines between the components and the connecting pipes between the ozone generator 4 and the input terminal 54 and the output terminal 55 are not shown in the figures.

[0046] With this design, when maintenance personnel or users inspect or maintain this ozone generator, they can disassemble and separate the first side plate 5 near the second cover plate 3 from the outer shell 1, and then pull the second cover plate 3 along the length of the outer shell 1 to separate the second cover plate 3 from the outer shell 1. The separation of the second cover plate 3 allows the first cover plate 2 to return to a swingable state. By swinging the first cover plate 2 away from the outer shell 1, the top of the outer shell 1 can be opened, which is very convenient and quick. Moreover, the first cover plate 2 adopts a swinging method to prevent the electrical connection harness from being pulled off during disassembly.

[0047] Meanwhile, the circuit assembly 6 can move along the length of the outer casing 1, making it easier to observe the ozone generator 4 located below the circuit assembly 6.

[0048] In this embodiment, the outer shell 1 includes a frame 11, a base plate 12, and a second side plate 13. The bottom of the frame 11 is provided with connecting pieces 111, and there are at least four connecting pieces 111. Each connecting piece 111 has a first connecting hole 112. The base plate 12 has a first bolt hole (not shown in the figure) corresponding to the position of the first connecting hole 112. The frame 11 and the base frame are connected by bolt threads.

[0049] The frame 11 is detachably connected to two second side plates 13 on both sides along its length, and the frame 11 is connected to two first side plates 5 at both ends along its length. The circuit assembly 6 is connected inside the frame 11 and can move along the length of the frame 11. The first cover plate 2 can be swung and overlapped on the top of the frame 11. The second cover plate 3 is connected inside the frame 11. The ozone generator 4 is connected to the base plate 12.

[0050] Specifically, the frame 11 can increase the overall rigidity and provide support points for each side plate. In this embodiment, the frame 11 is connected to the base plate 12 by four connecting pieces 111. When it is necessary to replace parts or carry out major repairs, the frame 11 and the base plate 12 can be separated by removing the bolts. The second side plate 13 can also be separated. Maintenance personnel or users can disassemble each component according to the inspection situation.

[0051] refer to Figure 5 The length direction of the frame is the y-direction, and the width direction is the x-direction.

[0052] Regarding the disassembly of the base plate 12, since it is impossible to observe the circuit components 6 from the front when the base plate 12 is disassembled, and it is also difficult to protect the wiring harness during disassembly, it is best to operate from the first cover plate 2 and the second cover plate 3 during inspection and maintenance.

[0053] Regarding the connection of the second side plate 13, it can be connected by screws through threaded holes.

[0054] In this embodiment, the inner side of the frame 11 has two first sliding grooves 113 arranged opposite to each other. The two first sliding grooves 113 are located near the top of the frame 11. The length of the two first sliding grooves 113 extends along the length direction of the frame 11. On the two first sliding grooves 113, there are limiting plates 115 on opposite sides. The limiting plates 115 are used for the first cover plate 2 to overlap the top of the frame 11. The two sides of the second cover plate 3 are respectively connected to the two first sliding grooves 113. The second cover plate 3 can move along the length direction of the first sliding groove 113. The two ends of the first sliding groove 113 are closed by the first side plate 5.

[0055] Specifically, the two first slide grooves 113 mainly provide the functions of limiting and sliding for the second cover plate 3. The limiting plate 115 on the first slide groove 113 provides the fulcrum for the first cover plate 2 to overlap. In the preferred embodiment, the limiting plate 115 is located at the bottom of the first slide groove 113. That is, when the first cover plate 2 overlaps on the limiting plate 115, the top of the first cover plate 2 and the top of the frame 11 are almost flush. After the second cover plate 3 is connected to the first slide groove 113, the top of the second cover plate 3 and the top of the frame 11 are also almost flush. The second cover plate 3 closes the top of the outer shell 1 by contacting the first cover plate 2, thus protecting the internal circuit components 6 and ozone generator 4.

[0056] In this embodiment, the inner side of the frame 11 has two second slide grooves 114 arranged opposite to each other. The two second slide grooves 114 are located below the two first slide grooves 113. The two sides of the circuit assembly 6 are respectively connected in the two second slide grooves 114. The circuit assembly 6 can move along the length direction of the second slide groove 114. The two ends of the second slide groove 114 are closed by the first side plate 5.

[0057] Similarly, the principle of the second slide 114 is the same as that of the first slide 113, but the objects are different. The second slide 114 is used to provide the circuit assembly 6 with the function of moving along the length direction of the frame 11. However, it should be noted that the cooperation between the circuit assembly 6 and the second slide 114 does not mean that the circuit assembly 6 can slide along the length direction of the second slide 114 when the frame 11 is tilted. The movement of the circuit assembly 6 on the second slide 114 requires the cooperation of external force. That is to say, the circuit assembly 6 will only move along the length direction of the second slide 114 when pulled by the user, and will not move due to its own weight.

[0058] Preferably, the first side plate 5 includes an upper plate 51 and a lower plate 52. Both the upper plate 51 and the lower plate 52 are connected to one end of the frame 11 along its length. The lower plate 52 is provided with at least four second connecting holes 521, and the upper plate 51 is provided with two third connecting holes 511. The top of the lower plate 52 is provided with a groove 522, and the bottom of the upper plate 51 is provided with a protrusion 515 that matches the groove 522. One end of the frame 11 along its length is provided with a second threaded hole (not shown in the figure) that matches the second connecting hole 521 and a third threaded hole (not shown in the figure) that matches the third connecting hole 511. The lower plate 52 is threadedly connected to the frame 11 by bolts. The lower end of the upper plate 51 is inserted into the lower plate 52, and the upper plate 51 is threadedly connected to the frame 11. The upper plate 51 can restrict the second cover plate 3 from disengaging from the first slide groove 113 and the circuit assembly 6 from disengaging from the second slide groove 114.

[0059] The first cover plate 2 is hinged to one of the upper plates 51, and one of the upper plates 51 has a power interface 512. The other upper plate 51 and the two lower plates 52 each have ventilation slots 53, and one of the lower plates 52 has an input terminal 54 and an output terminal 55.

[0060] Specifically, the first side plate 5 adopts an upper plate 51 and a lower plate 52. The upper plate 51 is mainly used to restrict the second cover plate 3 from detaching from the circuit assembly 6. More specifically, of the two upper plates 51, one upper plate 51 is hinged to the first cover plate 2, and the other upper plate 51 is mainly used to restrict the second cover plate 3 from detaching from the circuit assembly 6. In conjunction with the connection method with the lower plate 52, the lower end of the upper plate 51 is inserted into the upper end of the lower plate 52, and the lower end of the upper plate 51 is fixed by the lower plate 52. The upper plate 51 is then bolted to the frame 11 through its own two third connecting holes 511. Therefore, when it is necessary to open the first cover plate 2 and the second cover plate 3, it is only necessary to remove the two bolts on the upper plate 51 near the second cover plate 3 to remove the upper plate 51. Then, the first cover plate 2 and the second cover plate 3 can be operated in the same way. Compared with the multi-point fixing method, this embodiment only requires the removal of two bolts, which is more convenient and faster.

[0061] In this embodiment, the top of one of the lower plates 52 has a notch 513 that matches the width of the first cover plate 2, the bottom wall of the notch 513 has a first hinge 514, and one end of the first cover plate 2 along its width direction has a second hinge 23 that matches the first hinge 514. The first cover plate 2 is hinged at the notch 513.

[0062] In this design, the notch 513 on the upper plate 51 is mainly used to match the thickness and width of the first cover plate 2. When the first cover plate 2 swings to overlap the top of the frame 11, except at the hinge position, the end face of one end of the first cover plate 2 and the plate surface of the upper plate 51 that is hinged to it are almost flush, so that the overall aesthetics are maintained.

[0063] The first hinge 514 and the second hinge 23 can be made of a column and a pin. That is, a hollow column is set on the first cover plate 2 and a hollow column is also set on the upper plate 51. The columns are coaxially fitted and then a pin is inserted to achieve the hinge.

[0064] Preferably, the second cover plate 3 has protrusions 31 on both sides that match the first slide groove 113, the length of the protrusions 31 matches the length of the second cover plate 3, and the second cover plate 3 is slidably connected to the first slide groove 113 through the protrusions 31.

[0065] Specifically, the second cover plate 3 and the first slide groove 113 are connected by inserting a protrusion 31 into the first slide groove 113. The protrusion 31 is used to restrict the second cover plate 3 from disengaging from the first slide groove 113 in the vertical direction. Under the restriction of the protrusion 31, the second cover plate 3 can only move along the length direction of the first slide groove 113.

[0066] In this embodiment, the first cover plate 2 has a first step portion 22 at one end near the second cover plate 3, and the second cover plate 3 has a second step portion 32 that matches the first step portion 22 at one end near the first cover plate 2. When the first step portion 22 and the second step portion 32 are in contact, the second cover plate 3 can restrict the swing of the first cover plate 2. The top of the second cover plate 3 is provided with a handle 33.

[0067] In practical use, a first step 22 is provided on the first cover plate 2, and a second step 32 is provided on the second cover plate 3. The first cover plate 2 and the second cover plate 3 form a non-linear gap by fitting the first step 22 and the second step 32 together. Specifically, the first step 22 is an L-shaped structure, while the second step 32 is a 7-shaped structure, that is, an inverted L-shaped structure. Through the contact of the two matching structures, the swing of the first step 22 can be well restricted.

[0068] Specifically, the circuit assembly 6 includes a movable plate 61 and a circuit board 62 connected to the movable plate 61 by bolts and nuts. A pad (not shown in the figure) is fitted on the bolt, and the pad creates a gap between the circuit board 62 and the movable plate 61. The two sides of the movable plate 61 are connected to the second slide groove 114, and the movable plate 61 can move along the length direction of the second slide groove 114. The circuit board 62 is electrically connected to the ozone generator 4 and the control panel 21.

[0069] It should be noted that the electrical connection methods used for circuit board 62 and ozone generator 4, circuit board 62 and control panel 21, and circuit board 62 and the aforementioned power interface 512 are all electrical connection methods well known to those skilled in the art, specifically, they can be wires, but these are not within the scope of protection of this application.

[0070] The circuit board 62 is connected to the movable plate 61 by a combination of bolts, pads and nuts. The movable plate 61 is connected in the second slide 114. The circuit board 62 is moved along the length of the second slide 114 by the movable plate 61, which makes it easier to observe the ozone generator 4 located below the movable plate 61.

[0071] Furthermore, a cooling fan 7 is connected to the inner bottom surface of the outer casing 1. The cooling fan 7 is bolted to the inner bottom surface of the outer casing 1 and is electrically connected to the circuit assembly 6. Specifically, the cooling fan 7 cooperates with the ventilation slot 53 to improve the air exchange efficiency of the external airflow and the airflow inside the outer casing 1, thereby enhancing the heat dissipation performance.

[0072] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements or modifications can be made without departing from the principle of this application, and these improvements or modifications should also be considered within the scope of protection of this application.
