Abstract
Description
Technical Field
[0001] This utility model relates to the field of air purifier technology, and in particular to a portable air purifier. Background Technology
[0002] Currently, some air purifiers on the market work by spraying atomized traditional Chinese medicine into the air to kill bacteria and purify the air. To facilitate use in small spaces such as cars, some air purifiers are designed as small, portable devices. These air purifiers typically use an atomizer to atomize water into a mist and then spray it upwards. However, due to their small and portable design, the spray channel is too short, and some un-atomized droplets also spray out from the outlet. These droplets fall onto dashboards, leather seats, or tabletops, forming visible "medicinal stains" and affecting the user experience. Utility Model Content
[0003] This invention provides a portable air purifier that can reduce the spraying of liquid droplets and improve the user experience.
[0004] To solve the above problems, the present invention adopts the following technical solution:
[0005] This utility model provides a portable air purifier, including a base cup and a main unit. The base cup has an opening at the top, and the main unit is detachably connected to the base cup and covers the opening at the top of the base cup. The bottom surface of the main unit is provided with two downwardly extending support arms, and the bottom ends of the two support arms are connected to a base. The bottom surface of the main unit is also provided with a mist outlet extending through to the top surface of the main unit. The base is provided with a receiving groove, and an atomizer is provided in the receiving groove. The top surface of the base is provided with an opening communicating with the receiving groove, and the opening is coaxial with the mist outlet. A baffle is provided between the two support arms, and the two ends of the baffle are respectively connected to the two support arms. The baffle is located directly below the mist outlet.
[0006] In some embodiments, the baffle is inclined relative to the horizontal direction.
[0007] In some embodiments, the base includes a lower cover and an upper seat. The lower cover is fixed to the bottom surface of the upper seat by screws. The lower cover and the upper seat together form an accommodating groove. The opening is provided on the top surface of the upper seat.
[0008] In some embodiments, a sealing ring is fitted around the outer periphery of the lower cover, and the sealing ring abuts against the upper seat.
[0009] In some embodiments, a guide cylinder is also provided between the two support arms. The guide cylinder is located between the baffle and the base, and the guide cylinder is connected to the opening.
[0010] In some embodiments, the top surface of the main unit is provided with an air intake channel extending to the bottom surface of the main unit, and a sealing assembly is provided in the air intake channel, which can close the air intake channel when the bottom cup is tilted.
[0011] In some embodiments, the air intake channel includes a first air intake hole, a first air intake chamber, a connecting hole, a second air intake chamber, and a second air intake hole connected in sequence. The first air intake hole is disposed on the top surface of the main unit base, the first air intake chamber and the second air intake chamber are disposed inside the main unit base, the connecting hole is located at the lowest point of the first air intake chamber, and the second air intake hole is disposed on the bottom surface of the main unit base.

[0023] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.
[0024] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0025] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intermediary element (e.g., the third element) between the element and the other element.
[0026] An embodiment of this utility model provides a portable air purifier, such as... Figure 1-4 As shown, the device includes a base cup 100 and a main unit 200. The base cup 100 is used to hold the medicine, and its top opening allows medicine to be added. The main unit 200 is detachably connected to the base cup 100 and seals the top opening of the base cup 100. This detachable connection allows for easy assembly or disassembly of the main unit 200 and the base cup 100, facilitating the addition of medicine. Sealing the top opening of the base cup 100 also reduces medicine leakage.
[0027] The base 200 has two downward-extending support arms 310 on its bottom surface, with the bottom ends of the two support arms 310 connected to a base 320. The bottom surface of the base 200 also has a mist outlet 201 extending through to the top surface of the base 200. The base 320 has a receiving groove 301, within which an atomizer 330 is housed. The top surface of the base 320 has an opening communicating with the receiving groove 301, and the opening is coaxial with the mist outlet 201. A baffle 340 is positioned between the two support arms 310, with both ends of the baffle 340 connected to the two support arms 310 respectively. The baffle 340 is located directly below the mist outlet 201.
[0028] When the atomizer 330 is working, it atomizes the medicine into a mist and sprays it upward from the opening. Since the baffle 340 is located above the opening, the sprayed mist will be blocked by the baffle 340. Some un-atomized droplets will be intercepted by the baffle 340. These droplets are difficult to spray out from the mist outlet 201, which reduces the amount of droplets sprayed out and improves the user experience.
[0029] In this embodiment, the support arm 310, the base 320, and the baffle 340 can be integrally formed to facilitate product manufacturing.
[0030] In some embodiments, the baffle 340 is inclined relative to the horizontal direction. When mist is sprayed onto the baffle 340, the mist can diffuse not only to both sides of the baffle 340, but also along the baffle 340 to a higher position, thus preserving the upward tendency of the mist and making it easier for the mist to be sprayed out from the mist outlet 201. The angle of inclination of the baffle 340 can be determined by those skilled in the art according to the actual situation, for example, it can be 30°.
[0031] In some embodiments, the base 320 includes a lower cover 321 and an upper seat 322. The lower cover 321 is fixed to the bottom surface of the upper seat 322 by screws. The lower cover 321 and the upper seat 322 together form a receiving groove 301, and an opening is provided on the top surface of the upper seat 322. Since the lower cover 321 is fixed by screws, it can be disassembled, which facilitates the assembly of the atomizer 330.
[0032] In this embodiment, the upper seat 322 can be integrally formed with the support arm 310, so as to eliminate the process of connecting the upper seat 322 and the support arm 310.
[0033] Furthermore, a sealing ring 323 is provided around the outer periphery of the lower cover 321. The sealing ring 323 abuts against the upper seat 322. The sealing ring 323 increases the sealing performance and reduces the gap between the lower cover 321 and the upper seat 322, making it less likely for the medicine entering the receiving groove 301 to leak.
[0034] In some embodiments, a guide cylinder 350 is also provided between the two support arms 310. The guide cylinder 350 is located between the baffle 340 and the base 320, and the guide cylinder 350 is connected to the opening. In use, both the guide cylinder 350 and the base 320 are immersed in the medicine solution. The vibration of the atomizer 330 will generate water flow in the medicine solution. The guide cylinder 350 can guide the water flow, so that the water flow is concentrated and flows upward, making it easier to generate mist on the water surface.
[0035] In some embodiments, the top surface of the main unit 200 is provided with an air intake channel 210 extending to the bottom surface of the main unit 200. When the mist is sprayed out from the mist outlet 201, it carries the gas inside the bottom cup 100 out of the mist outlet 201, while external air enters into the bottom cup 100 through the air intake channel 201. This allows the gas to circulate and ensures that the mist is smoothly sprayed out from 201. A sealing assembly is provided inside the air intake channel 210, which can close the air intake channel when the bottom cup 100 is tilted. When the bottom cup 100 is tilted, the air intake channel is closed, and the medicine inside the bottom cup 100 will not flow out through the air intake channel, thereby preventing medicine leakage due to the bottom cup 100 being tilted.
[0036] Furthermore, the air intake channel 210 includes a first air intake hole, a first air intake chamber 212, a connecting hole 213, a second air intake chamber 214, and a second air intake hole 215 connected in sequence. The first air intake hole is located on the top surface of the main unit 200, the first air intake chamber 212 and the second air intake chamber 214 are located inside the main unit 200, the connecting hole 213 is located at the lowest point of the first air intake chamber 212, and the second air intake hole 215 is located on the bottom surface of the main unit 200.
[0037] The sealing assembly includes a gravity ball 410, a first connecting rod 421, a connecting plate 423, a second connecting rod 422, a sealing gasket 430, and an elastic element 440. The gravity ball 410 is disposed in the first air intake chamber 212 and can roll in the first air intake chamber 212. When the bottom cup 100 is correctly placed, under the action of gravity, the gravity ball 410 rolls to the lowest point of the first air intake chamber 212. When the bottom cup 100 is tilted, the gravity ball 410 is removed from the lowest point of the first air intake chamber 212. The first connecting rod 421 is connected to the top surface of the connecting plate 423 and passes through the connecting hole 213. The connecting plate 423 and the elastic element 440 are both located in the second air intake chamber 214. The second connecting rod 422 is connected to the bottom surface of the connecting plate 423 and passes through the second air intake hole 215. The sealing gasket 430 is sleeved on the second connecting rod 422 and located on the bottom surface of the main unit 200. The elastic element 440 abuts against the bottom wall of the connecting plate 423 and the second air intake chamber 214.
[0038] When the bottom cup 100 is correctly placed, the gravity ball 410 rolls to the lowest point of the first air inlet chamber 212. The gravity ball 410 pushes the first connecting rod 421 downward, which in turn causes the sealing gasket 430 to move downward. The sealing gasket 430 will move away from the bottom surface of the main unit 200, and the second air inlet 215 will open. Outside air can enter the interior of the bottom cup 100 in sequence through the first air inlet, the first air inlet chamber 212, the connecting hole 213, the second air inlet chamber 214, and the second air inlet 215.
[0039] When the bottom cup 100 is tilted, the gravity ball 410 moves away from the lowest point of the first air intake chamber 212. The gravity ball 410 no longer presses down on the first connecting rod 421, and the elastic element 440 pushes the connecting plate 423 upwards, correspondingly causing the sealing gasket 430 to move upwards. The sealing gasket 430 abuts against the bottom surface of the main unit 200, sealing the second air intake 215. The medicine inside the bottom cup 100 cannot enter the air intake channel 210 through the second air intake 215.
[0040] In this embodiment, the first connecting rod 421, the connecting plate 423, and the second connecting rod 422 can be integrally formed, which facilitates the manufacturing of the product.
[0041] Furthermore, the elastic element 440 is a spring sleeved on the outside of the second connecting rod 422. The two ends of the spring abut against the bottom wall of the connecting plate 423 and the second air intake chamber 214, respectively. The second connecting rod 422 can restrict the lateral movement of the spring and guide the extension and retraction of the spring.
[0042] To prevent the gravity ball 410 from completely blocking the connection hole 213 when it rolls to the lowest point of the first air intake chamber 212, a guide groove can be provided on the bottom wall of the first air intake chamber 212. One end of the guide groove is connected to the connection hole 213, and the other end can extend to the top wall of the first air intake chamber 212. Airflow can flow to the connection hole 213 through the guide groove.
[0043] In some embodiments, the main unit 200 can be detachably connected to the base cup 100 by means of snap-fit connection, threaded connection, or other methods.
[0044] The terms and words used in the foregoing description and claims are not limited to their literal meaning, but are merely used by the applicant to enable a clear and consistent understanding of the present invention. Therefore, those skilled in the art should understand that the foregoing description of various embodiments of the present invention is for illustrative purposes only, and not intended to limit the present invention as defined by the appended claims and their equivalents.
