Description

Technical Field

[0001] This utility model relates to the field of humidifier technology, and in particular to an antibacterial agent slow-release device. Background Technology

[0002] As people's demands for quality of life increase, humidifiers have become common appliances in many homes and offices. However, with long-term use, traditional humidifiers are prone to accumulating dirt and bacteria in the water tank, which not only affects the humidification effect but may also pose a potential threat to the user's health. To solve this problem, various antibacterial agent slow-release devices have emerged on the market, which achieve water sterilization by continuously releasing antibacterial agents into the water.

[0003] However, existing antibacterial agent sustained-release devices still have some shortcomings. First, most sustained-release devices have a short service life and require frequent replacement, increasing user costs and maintenance burden. Second, the release rate of existing sustained-release devices is difficult to control precisely, easily resulting in the antibacterial agent being released too quickly or too slowly, affecting the bactericidal effect. Furthermore, some sustained-release devices have complex structures, making them inconvenient for users to operate and replace the released agent. Finally, existing sustained-release devices often lack effective sealing mechanisms, making them susceptible to moisture intrusion, which affects the sustained-release effect and service life.

[0004] Therefore, there is an urgent need for a slow-release device for antibacterial agents that is simple in structure, has a long service life, a controllable release rate, and good sealing performance, in order to solve the problems existing in the current technology and improve the safety and user experience of humidifiers. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an antibacterial agent slow-release device that can effectively inhibit the growth of bacteria in the humidifier water tank for a long time, in order to address the problems of dirt accumulation and bacterial growth in the water tank of humidifiers after long-term use, as well as the shortcomings of existing antibacterial agent slow-release devices with short service life and frequent replacement.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: an antibacterial agent sustained-release device is provided, including a shell, a liquid storage component, a sealing component, and a sustained-release channel. One end of the shell is open to form a receiving cavity. The liquid storage component is used to adsorb the sustained-release agent and is housed in the receiving cavity. The sealing component is covered at the open end of the receiving cavity to seal the receiving cavity. The sustained-release channel passes through both ends of the sealing component to allow the sustained-release agent to seep out from the receiving cavity.

[0007] Preferably, the antibacterial agent sustained-release device further includes a cover, which is disposed on one end of the sealing member and connected to the open end of the housing; the side wall of the cover is provided with a window to allow the sustained-release agent seeping from the receiving cavity to diffuse outward.

[0008] Furthermore, the inner wall of the cover is provided with a buckle, and the outer wall of the opening end of the housing is provided with a slot. The cover and the housing are detachably connected by the buckle and the slot.

[0009] Furthermore, the slot includes a guide slot extending in the vertical direction and a limiting slot extending in the horizontal direction.

[0010] Optionally, the limiting slot is provided with a buckle groove at intervals in the extending direction, and the buckle groove is adapted to the buckle.

[0011] Preferably, a counterweight is embedded in the top wall of the cover body.

[0012] Furthermore, the seal has a built-in needle tube that penetrates the seal to form the slow-release channel, with one end of the needle tube extending into the liquid reservoir.

[0013] Furthermore, the inner diameter of the needle is 0.2-0.3 mm.

[0014] Optionally, the seal may be integrally convex in a direction away from the receiving cavity to form an arc surface, and the needle tube may be located on the arc surface.

[0015] Preferably, the sealing element is made of silicone.

[0016] The beneficial effects of this invention are as follows: By adsorbing the slow-release agent into the storage container and encapsulating it within the housing, and simultaneously providing a slow-release channel passing through the seal, the slow-release agent can be evenly diffused throughout the water body. Compared to existing technologies, this invention's antibacterial slow-release device achieves long-term stable release of the slow-release agent, effectively extending the device's lifespan and reducing replacement frequency. Simultaneously, it effectively inhibits bacterial growth within the humidifier's water tank for an extended period, preventing potential health threats from water tank buildup and bacterial proliferation. Furthermore, the counterweight on the top wall of the cover ensures stable sinking of the slow-release device, guaranteeing its proper function and further enhancing its practicality.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] The following is combined Figures 1-2 This invention describes an antibacterial agent slow-release device, which is placed inside the water tank of a humidifier. Its main purpose is to inhibit the growth of bacteria within the humidifier's water tank, ensuring the safety and cleanliness of the humidified water and improving the user experience.

[0028] Please refer to Figures 1-2 The antibacterial agent sustained-release device includes a housing 10, a liquid reservoir 20, a sealing element 30, and a sustained-release channel 40. One end of the housing 10 is open, forming a receiving cavity 11 for containing the sustained-release agent. The liquid reservoir 20 adsorbs the sustained-release agent and is contained within the receiving cavity 11. The sealing element 30 covers the open end of the receiving cavity 11 to seal it. The sustained-release channel 40 extends through both ends of the sealing element 30, allowing the sustained-release agent to seep out of the receiving cavity 11.

[0029] Specifically, the liquid storage component 20 is made of a porous, absorbent material, such as cotton, cellulose, or polyester. The slow-release agent is fully adsorbed by the liquid storage component 20, thereby slowing down the release rate of the slow-release agent and making the slow-release agent diffuse more evenly in the water. One end of the slow-release channel 40 extends into the interior of the liquid storage component 20, and the other end passes through the seal 30 to communicate with the outside, allowing the slow-release agent to be released stably from the liquid storage component 20 into the water in the humidifier tank over a long period of time. Compared with the solution of directly filling the slow-release agent in liquid form into the shell 10, the slow-release device of this embodiment has a simple structure, long service life, and better long-term antibacterial effect.

[0030] In one embodiment, the antibacterial agent sustained-release device further includes a cover 50, which is placed over one end of the sealing member 30 and connected to the open end of the housing 10. A window 52 is provided on the side wall of the cover 50 to allow the sustained-release agent seeping from the receiving cavity 11 to diffuse outwards. It should be noted that this embodiment does not limit the connection method between the housing 10 and the cover 50. Specifically, the housing 10 and the cover 50 can be fixedly connected by methods such as ultrasonic welding, or they can be connected in a detachable manner. Preferably, the housing 10 and the cover 50 are connected in a detachable manner to facilitate the reuse of the sustained-release device through secondary filling of the sustained-release agent. The detachable connection methods between the housing 10 and the cover 50 include threaded connection, snap-fit ​​connection, etc. When the cover 50 is connected to the open end of the housing 10, the cover 50 presses against the sealing member 30 to ensure the sealing of the receiving cavity 11.

[0031] In one embodiment, the inner wall of the cover 50 is provided with a buckle 51, and the outer wall of the opening end of the housing 10 is provided with a slot 12. The cover 50 and the housing 10 are detachably connected by the buckle 51 and the slot 12. Similarly, the inner wall of the cover 50 can also be provided with a slot 12, and the outer wall of the opening end of the housing 10 can be provided with a buckle 51, which can also achieve a detachable connection between the cover 50 and the housing 10.

[0032] In one embodiment, the slot 12 includes a guide slot 121 extending vertically and a limiting slot 122 extending horizontally. Specifically, when the cover 50 is installed on the housing 10, the latch 51 first moves along the guide slot 121 to cover the opening end of the housing 10, and then moves along the limiting slot 122 to limit the cover 50 to the opening end of the housing 10, thereby connecting the cover 50 to the housing 10. At this time, the cover 50 presses against the sealing member 30 to seal the receiving cavity 11. That is, when installing the cover 50, the cover 50 is first pressed downward against the sealing member 30 to move the latch 51 along the guide slot 121 to the bottom end, and then the cover 50 is tightened laterally to move the latch 51 along the limiting slot 122 to the farthest end.

[0033] In one embodiment, a latching groove 13 is provided at intervals along the extending direction of the limiting groove 122. The latching groove 13 is adapted to the latch 51 to further enhance the connection stability. Specifically, when the cover 50 is tightened laterally, causing the latch 51 to move to the farthest end of the limiting groove 122, the cover 50 is further tightened so that the latch 51 falls into the latching groove 13, thereby securing the cover 50 to the open end of the housing 10.

[0034] In one embodiment, a counterweight 53 is embedded in the inner top wall of the cover 50. The counterweight 53 increases the weight of the cover 50, enabling the device to remain stable in a liquid environment, preventing it from floating, and ensuring the stability of the slow-release effect. Specifically, a protrusion 54 is provided on the inner sidewall of the cover 50, and a space for receiving the counterweight 53 is defined between the protrusion 54 and the inner top wall of the cover 50, making it difficult for the counterweight 53 to fall out when embedded in the space.

[0035] In one embodiment, the seal 30 has a built-in needle 41, which extends through the seal 30 to form a slow-release channel 40. One end of the needle 41 extends into the liquid reservoir 20, and the other end passes through the seal 30 to communicate with the outside.

[0036] In one embodiment, the inner diameter of the syringe 41 is 0.2-0.3 mm. This small inner diameter can control the exudation rate of the sustained-release agent, achieving a stable sustained-release effect over a long period of time. Preferably, the inner diameter is 0.3 mm. This size provides sufficient flow to meet the sustained-release requirements while maintaining a certain level of fluid resistance to prevent clogging caused by particulate impurities or microbial growth.

[0037] In one embodiment, the seal 30 protrudes 54 along a direction away from the receiving cavity 11 to form an arc surface 31, and the needle 41 is located on the arc surface 31. This arc surface 31 design allows the sustained-release agent to be evenly dispersed, while reducing the accumulation of the sustained-release agent on the surface of the seal 30, thereby improving the sustained-release efficiency.

[0038] In one embodiment, the seal 30 is made of silicone, which has good elasticity and sealing properties, allowing it to fit tightly against the opening of the housing 10 and prevent leakage of the slow-release agent. Simultaneously, silicone has a certain degree of chemical resistance and will not react with common antibacterial agents, ensuring the long-term stable operation of the slow-release device.

[0039] During use, the antibacterial agent is first injected into the reservoir 20, which then absorbs the agent and is contained within the receiving cavity 11 of the housing 10. The sealing element 30 is then placed over the opening of the receiving cavity 11 and secured with the cap 50. The antibacterial agent slowly seeps out through the slow-release channel 40 formed by the syringe 41 and diffuses outward through the window 52 on the side wall of the cap 50, achieving an antibacterial effect. Due to the small inner diameter of the syringe 41 and the slow seepage rate of the antibacterial agent, it can exert its antibacterial effect for a long time. When the antibacterial agent is used up, the cap 50 and the sealing element 30 can be easily removed and replaced with new antibacterial agent using the design of the buckle 51 and the slot 12, enabling reuse.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
