[0031] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0032] The following is in conjunction with the appendix Figures 1-8 This embodiment will be described in further detail.

[0033] Combination Figures 1-4 As shown, a portable one-way membrane application kit in this embodiment includes a cover 100 and a cover plate 110 for pressing a one-way breathable membrane 120 into the cover 100. The cover plate 110 has a breathable groove 111, and the cover 100 has a through hole that penetrates the cover 100. The through hole has a stepped frame 101 for the cover plate 110 to overlap. The stepped frame 101 has an installation groove 102 for the one-way breathable membrane 120 to be installed on the side facing the cover plate 110. The cover plate 110 has snap-fit ​​members on both sides, and the stepped frame 101 has a snap-fit ​​groove 103 for the corresponding snap-fit ​​members to snap into. The cover 100 has pressing members on both sides, which are used to drive the snap-fit ​​members to deform so as to release their snap-fit ​​fixation in the snap-fit ​​groove 103.

[0034] In this embodiment, the cover plate 110 is snapped into the corresponding snap-fit ​​groove 103 by the snap-fit ​​pieces on both sides, so that the cover plate 110 can be inserted and installed on the step frame 101. By fixing the cover plate 110 on the step frame 101, the one-way breathable membrane 120 is pressed into the mounting groove 102 to realize the assembly of the kit.

[0035] To ensure a tighter seal between the cover plate 110 and the one-way breathable membrane 120, a raised ring gasket 400 is provided on the lower side of the cover plate 110 for pressing the one-way breathable membrane 120 into the mounting groove 102. The raised ring gasket 400 is made of rubber. When the cover plate 110 is installed on the step frame 101, the raised ring gasket 400 can press the side of the one-way breathable membrane 120 tightly against the bottom wall of the mounting groove 102, making the installation of the one-way breathable membrane 120 more secure and stable. Of course, to improve the sealing effect, a sealing gasket is also provided on the bottom wall of the mounting groove 102. The raised ring gasket 400 is used to press the one-way breathable membrane 120 tightly onto the sealing gasket, thereby improving the sealing effect of the one-way breathable membrane 120 installation.

[0036] In practical use, this kit can be applied to the field of essential oil diffusion technology, such as... Figure 8 As shown, the essential oil box 700 includes an upper opening and contains liquid essential oil. The kit is fixedly installed at the upper opening of the essential oil box 700, thereby allowing the liquid essential oil in the essential oil box 700 to evaporate to the outside through the one-way breathable membrane 120 and the breathable groove 111. At the same time, the one-way breathable membrane 120 can block the liquid essential oil to prevent the liquid essential oil from seeping out.

[0037] Specifically, in order to better achieve the assembly and disassembly of this kit at the upper opening of the essential oil box 700, combined with Figure 7 and Figure 8As shown, in this embodiment, the lower side of the cover 100 and its two sides are provided with insertion slots 601 facing each other. The side wall of the upper opening of the essential oil box 700 protrudes outward to form an abutment ring 701 that can extend into the through hole of the cover 100 and slide against the side wall of the through hole. An insertion block 710 is provided on the upper side of the essential oil box 700 outside the abutment ring 701, which can be inserted into the corresponding insertion slot 601. The outer side wall of the insertion block 710 is provided with a deformable compression ring 711, and the inner wall of the insertion slot 601 has a recessed groove for the compression ring 711 to engage. Thus, the insertion block 710 is aligned with the corresponding insertion slot 601. When the abutment ring 701 is inserted into the through hole so that the kit overlaps the upper side wall of the essential oil box 700, the upper end of the abutment ring 701 abuts against the lower side wall of the stepped frame 101. At the same time, the compression ring 711 is inserted into the corresponding recessed groove so that the insertion block 710 is fixed in the insertion groove 601, thereby fixing the cover 100 onto the essential oil box 700, thus realizing the installation of the kit on the essential oil box 700. At the same time, when it is necessary to replenish the liquid essential oil in the essential oil box 700, the operator uses greater force to separate the cover 100 and the essential oil box 700 so that the compression ring 711 disengages from the recessed groove.

[0038] Specifically, in order to prevent liquid essential oil from leaking at the contact point between the abutting ring 701 and the stepped frame 101, in this embodiment, a sealing gasket is provided on the lower side wall of the stepped frame 101 to abut against the abutting ring 701.

[0039] In practical use, this embodiment facilitates the replacement of the one-way breathable membrane 120 when the kit is installed on the essential oil box 700. By setting up the pressing parts, the operator can press the two pressing parts close to each other, which will deform the snap-fit ​​parts and release them from the snap-fit ​​parts fixed in the snap-fit ​​groove 103, thereby facilitating the removal of the cover plate 110 and making the replacement of the one-way breathable membrane 120 more convenient.

[0040] Combination Figure 5 As shown, in this embodiment, the snap-fit ​​component includes a first snap-fit ​​plate 112, wherein the first snap-fit ​​plate 112 is integrally formed on both sides of the cover plate 110. Both the cover plate 110 and the first snap-fit ​​plate 112 are made of plastic, thereby giving the first snap-fit ​​plate 112 a certain deformation capability. The first snap-fit ​​plate 112 has a first protrusion portion 401 on its mutually distant sides and at its lower end. The side wall of the first protrusion portion 401 is provided with a first guide surface. The side wall of the snap-fit ​​groove 103 is provided with a snap-fit ​​groove 411 for the first protrusion portion 401 to be snapped into.

[0041] With the above structure, the first snap-fit ​​plate 112 bends and deforms during the process of inserting the first snap-fit ​​plate 112 and the first protrusion 401 into the corresponding snap-fit ​​groove 103, so that the first snap-fit ​​plate 112 and the first protrusion 401 can be inserted and moved in the snap-fit ​​groove 103. When it is inserted into the snap-fit ​​groove 103 and the first protrusion 401 is opposite to the groove 411, the first snap-fit ​​plate 112 is reset so that the first protrusion 401 extends into the groove 411. By using the abutment between the first protrusion 401 and the side wall of the groove 411, the snap-fit ​​member is fixed in the snap-fit ​​groove 103, that is, the cover plate 110 is installed on the step frame 101.

[0042] Specifically, the first guide surface is located at the lower outer end of the first protrusion 401. When the first snap-fit ​​plate 112 and the first protrusion 401 are inserted into the snap-fit ​​groove 103, the first guide surface first abuts against the opening sidewall of the snap-fit ​​groove 103, so that the first snap-fit ​​plate 112 deforms, thereby facilitating the snap-fit ​​member to extend into the corresponding snap-fit ​​groove 103, thus facilitating the insertion and installation of the cover plate 110.

[0043] Combination Figure 5 and Figure 6 As shown, in this embodiment, the two sides of the cover 100 are recessed to form pressing grooves 104 corresponding to the snap-fit ​​grooves 103;

[0044] The pressing component includes a button 130 that is slidably disposed in the pressing groove 104. The button 130 is provided with a push rod 421 that extends through the cover 100 into the slot 411. Pressing the button 130 is used to drive the push rod 421 to press the first guide surface so that the first protrusion 401 disengages from the slot 411.

[0045] In this embodiment, by pressing the button 130, the button 130 is moved into the pressing groove 104. At this time, it drives the push rod 421 to extend into the slot 411 and squeeze the first guide surface so that the first protrusion 401 is disengaged from the slot 411, thereby releasing the fixing of the snap fastener in the snap fastener groove 103.

[0046] In order to enable the push rod 421 to better push the first guide surface, the end of the push rod 421 extending into the slot 411 forms a hemispherical surface that matches the first guide surface. By sliding the hemispherical surface on the first guide surface, the first protrusion 401 can be disengaged from the slot 411, thereby releasing the fixing of the snap-fit ​​member in the snap-fit ​​groove 103. At this time, pressing the button 130 again can make the hemispherical surface continue to press the first guide surface, thereby pushing the snap-fit ​​member to move upward along the snap-fit ​​groove 103, that is, driving the cover plate 110 to move upward, so that the cover plate 110 protrudes out of the cover body 100, thereby facilitating the operator to disassemble the cover plate 110.

[0047] In this embodiment, in order to achieve sliding installation of the button 130 within the pressing groove 104, the bottom wall of the pressing groove 104 is provided with a groove 431 for the button 130 to extend into. Specifically, as shown in the figure... Figure 5 As shown, the distance between the two sides of the groove 431 is longer than the distance between the two sides of the pressing groove 104, that is, a step is formed between the corresponding side walls of the groove 431 and the pressing groove 104. The button 130 has a mounting cavity with an opening facing the groove 431. A deformable second snap-fit ​​plate 510 is provided on the side wall of the mounting cavity. A second protrusion 511 that can be snapped into the groove 431 is provided on the outer side wall of the second snap-fit ​​plate 510. A second guide surface is provided on the side wall of the second protrusion 511. A protrusion 420 is provided in the mounting cavity. The push rod 421 is installed on the protrusion 420. A spring 440 is sleeved on the protrusion 420. One end of the spring 440 The first end abuts against the side wall of the groove 431, and the other end abuts against the side wall of the mounting cavity, so that the spring 440 is installed. The spring 440 is used to push the button 130 out of the groove 431 so that the second protrusion 511 abuts against the corresponding step. Thus, the button 130 is slidably installed in the pressing groove 104. At this time, the push rod 421 is in the retracted state so that it does not affect the first protrusion 401 from being inserted into the slot 411. When the operator presses the button 130 to bring them closer together, the push rod 421 can be inserted into the slot 411 and the locking groove 103 so as to remove the cover plate 110.

[0048] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
