Description

Technical Field

[0001] This utility model relates to the field of nebulizer technology, and more specifically, to a household nebulizer. Background Technology

[0002] Nebulizers have a wide range of uses, including daily respiratory care: using saline or distilled water to humidify the airways and relieve discomfort in dry environments, such as a dry, itchy throat or nasal congestion; and home humidification, similar to a humidifier. Nebulizers designed for home humidification increase air humidity by releasing water vapor or mist, making them particularly suitable for use in dry environments. They improve indoor humidity by converting water molecules into tiny water mists or vapors that diffuse into the air, preventing the air from becoming too dry and improving living comfort.

[0003] In actual use, tap water is added to the water tank inside the nebulizer. The ultrasonic transducer in the atomization channel at the bottom of the water tank vibrates to generate water mist, which is then diffused into the air through the atomization channel to improve indoor humidity. However, when tap water is added to the water tank, it may contain bacteria, which can enter the air through the atomization process, increasing the risk of respiratory infections, especially for people with weakened immune systems. Ordinary filter plates cannot effectively filter these bacteria, thus affecting the actual use of the nebulizer and requiring further improvement. Utility Model Content

[0004] The purpose of this invention is to provide a household nebulizer to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A household nebulizer includes a cover and a lower housing. The lower housing houses a filter water tank with an upper opening and a nebulizing water tank, which are connected. An ultrafiltration membrane is installed in the filter water tank via an mounting assembly. The ultrafiltration membrane is used to ultrafilter water added to the filter water tank. A cover is located at the opening of the filter water tank. A fixing block with a locking hole is located on the opposite upper side wall of the filter water tank. A chamber is located inside the cover. A slot communicating with the chamber is located on the lower side of the cover, allowing the corresponding fixing block to be inserted into the chamber. A locking assembly is located inside the chamber and is inserted into the corresponding locking hole to secure the cover to the filter water tank. A connecting assembly is also located inside the chamber, connecting to the mounting assembly for replacing the ultrafiltration membrane.

[0007] Furthermore, the filter tank is provided with a filter chamber. On the opposite side wall of the filter chamber, there is a sliding groove with an upper opening along its height direction. The sliding groove is T-shaped. The mounting assembly includes a sliding plate that is located in the sliding groove and adapted to the sliding groove. The sliding plate is L-shaped. There is a placement block at the bottom of the sliding plate. There is an overlapping block on the other opposite side wall of the filter chamber. The placement block and the overlapping block are used to realize the overlapping placement of the ultrafiltration membrane in the filter chamber. The lower side of the tank cover is provided with a notch for the sliding plate to extend into the chamber. The connecting assembly abuts against the lower end of the sliding plate to realize that the tank cover drives the sliding plate to drive the ultrafiltration membrane to slide out of the filter chamber.

[0008] Furthermore, the locking assembly includes inclined blocks disposed opposite each other within the cavity, a locking rod provided on one side wall of the inclined blocks, and an abutment plate disposed opposite each other within the cavity. The locking rod passes through the abutment plate, and a first spring is sleeved on the locking rod located between the abutment plate and the inclined blocks. The first spring is used to drive the inclined blocks to reset, thereby disengaging the locking rod from the lock hole. The locking assembly also includes a driving member disposed within the cavity, which is used to drive the two inclined blocks to move away from each other, thereby inserting the locking rod into the corresponding lock hole.

[0009] Furthermore, the bottom wall of the chamber is provided with a T-shaped groove, and the bottom wall of the inclined block is provided with a slider that can extend into the groove and is adapted to the groove.

[0010] Furthermore, a drive box is provided on the side of the lid, and a drive cavity communicating with the chamber is provided inside the drive box; the drive component includes a drive block provided in the chamber, a first inclined surface is provided on the other side wall of the inclined block, a second inclined surface adapted to the first inclined surface is provided on the opposite side wall of the drive block, a drive rod extending into the drive cavity is provided on the upper side wall of the drive block, the drive rod extends through the drive cavity, and a second spring is provided on the drive rod located in the drive cavity, the second spring being used to push the drive downward.

[0011] Furthermore, the drive block has a cavity; the connecting assembly includes a square cylinder disposed opposite to each other in the cavity, a slidable square column disposed in the square cylinder, a rotatable threaded rod disposed in the square cylinder, one end of the threaded rod being threaded into the square column, and the other end of the threaded rod being threaded into the cavity; the connecting assembly also includes a power component disposed in the cavity, the power component being used to drive the two threaded rods to rotate synchronously.

[0012] Furthermore, the power component includes a rotating rod that extends through the drive rod into the cavity. The lower end of the rotating rod is provided with a first bevel gear, and the other end of the threaded rod located in the cavity is provided with a second bevel gear that meshes with the first bevel gear. The rotation of the first bevel gear is used to drive the two second bevel gears to rotate synchronously.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, through the setting of an ultrafiltration membrane, enables the ultrafiltration membrane to ultrafilter water, thereby better removing bacteria from the water, so that the atomized water mist does not contain bacteria.

[0015] 2. This utility model, through the setting of the installation component, allows the ultrafiltration membrane to be slidably installed in the water filtration tank. When the ultrafiltration membrane needs to be replaced, through the setting of the connecting component, the connecting component can be connected to the installation component, and then the installation component can be connected to the tank cover.

[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 1-8 As shown, a household nebulizer in this embodiment includes a cover 101 and a lower housing 100. The lower housing 100 contains a filter water tank 300 with an upper opening and a nebulizing water tank 200, which are connected. An ultrafiltration membrane 302 is installed in the filter water tank 300 via an assembly. The ultrafiltration membrane 302 is used to ultrafilter the water added to the filter water tank 300. A cover 201 is provided at the opening of the filter water tank 300. A fixing block is provided on the side wall, and a locking hole 304 is provided on the fixing block. A chamber is provided inside the cover 201. The lower side of the cover 201 is provided with a slot 500 communicating with the chamber. The slot 500 is used for the corresponding fixing block to be inserted into the chamber. A locking component is provided in the chamber. The locking component is inserted into the corresponding locking hole 304 to realize the fixed installation of the cover 201 on the filter water tank 300. A connecting component is also provided in the chamber. The connecting component is used to connect with the installation component to realize the replacement of the ultrafiltration membrane 302.

[0034] In this embodiment, the bottom of the atomizing water tank 200 is provided with an atomizing channel 205 along its height direction, and an atomizing component is provided in the atomizing channel 205. Both the atomizing channel 205 and the atomizing component are existing structures.

[0035] In actual use, the cover 101 and the lower housing 100 are separated, and the locking component is driven to disengage from the corresponding lock hole 304. This releases the cover 201 from the filter water tank 300, allowing the filter water tank 300 to be opened. Water is then poured into the filter water tank 300. The ultrafiltration membrane 302 is located in the middle of the filter water tank 300. The ultrafiltration membrane 302 can ultrafilter the water, thereby effectively removing bacteria from the water. Since the filter water tank 300 and the atomizing water tank 200 are connected, the ultrafiltered water can enter the atomizing water tank 200. The cover 101 is then installed on the lower housing 100. The atomizing component atomizes the water in the atomizing channel 205 into a mist, which then floats out of the cover 101 through the atomizing channel 205, ensuring that the mist does not contain bacteria.

[0036] The cover 101 includes a first cover 103 and a second cover 104. The first cover 103 is installed at the opening of the filter water tank 300, and the second cover 104 is installed at the opening of the atomizing water tank 200. When water needs to be added to the filter water tank 300, the first cover 103 is removed to expose the filter water tank 300 for water addition. The second cover 104 is always installed on the atomizing water tank 200 to prevent unfiltered water from entering the atomizing water tank 200 during water addition. Specifically, the upper side of the second cover 104 is provided with a mist outlet 102, which allows water mist to drift out.

[0037] It should be noted that since the pore size of the ultrafiltration membrane 302 is usually between 0.001 and 0.02 micrometers, it takes a certain amount of time for the ultrafiltration membrane 302 to filter water. By placing the ultrafiltration membrane 302 in the middle of the water filtration tank 300, there is a certain water storage space on the upper side of the ultrafiltration membrane 302, which can ensure that the water entering the water filtration tank 300 can be filtered.

[0038] Specifically, the filter water tank 300 and the atomizing water tank 200 are connected to each other. The side walls of the filter water tank 300 and the atomizing water tank 200 are provided with water outlet grooves 305. The water outlet grooves 305 are sealed with rubber rings to prevent water leakage between the two water outlet grooves 305. The water outlet grooves 305 are designed to form a U-shape between the filter water tank 300 and the atomizing water tank 200, so that the liquid levels of the two are flush, allowing water in the filter water tank 300 to enter the atomizing water tank 200.

[0039] The water filter tank 300 is made of transparent material, and an observation port 105 is provided on the outer side wall of the lower housing 100. The observation port 105 allows the operator to observe the water level in the water filter tank 300 and add water accordingly.

[0040] In actual use, the ultrafiltration membrane 302 can be slidably installed in the water filter tank 300 through the installation component. When the ultrafiltration membrane 302 needs to be replaced, the connection component can be connected to the installation component, and then the installation component can be connected to the tank cover 201. So when the tank cover 201 is removed from the water filter tank 300, the tank cover 201 can drive the installation component to remove the ultrafiltration membrane 302 from the water filter tank 300 for replacement.

[0041] The slot 500 allows the cover 201 to be placed on the upper side of the filter tank 300, and the fixing block can be inserted into the chamber through the slot 500. The locking component can be inserted into the lock hole 304, thereby fixing the fixing plate 303 in the chamber, and thus fixing the cover 201 on the filter tank 300.

[0042] There is a gap between the cover 201 and the opening of the filter water tank 300 so that the water in the filter water tank 300 can be filtered.

[0043] Combination Figures 3-5 As shown, in this embodiment, the filter tank 300 is provided with a filter chamber 301. A sliding groove 402 with an upper opening is provided on the opposite side wall of the filter chamber 301 along its height direction. The sliding groove 402 is T-shaped. The mounting assembly includes a sliding plate 306 provided in the sliding groove 402 and adapted to the sliding groove 402. The sliding plate 306 is L-shaped. A placement block 400 is provided at the bottom of the sliding plate 306. An overlapping block 401 is provided on the other opposite side wall of the filter chamber 301. The placement block 400 and the overlapping block 401 are used to realize the overlapping placement of the ultrafiltration membrane 302 in the filter chamber 301. The lower side of the tank cover 201 is provided with a notch 501 for the sliding plate 306 to extend into the chamber. The connecting assembly abuts against the lower end of the sliding plate 306 to realize that the tank cover 201 drives the sliding plate 306 to drive the ultrafiltration membrane 302 to slide out of the filter chamber 301.

[0044] In actual use, the sliding plate 306 is slid into the sliding groove 402 through the upper opening of the sliding groove 402. When the bottom wall of the sliding plate 306 abuts against the bottom wall of the sliding groove 402, the upper sides of the placement block 400 and the overlapping block 401 are flush. By setting the placement block 400 and the overlapping block 401, the filter membrane can be placed on the placement block 400 and the overlapping block 401, so that the ultrafiltration membrane 302 can be placed in the filter chamber 301.

[0045] In actual use, the ultrafiltration membrane 302 is installed in the mounting frame. A rubber pad is provided on the outer wall of the mounting frame. The rubber pad can seal the outer wall of the mounting frame and the side wall of the filter chamber 301, so that the water above the ultrafiltration membrane 302 will not leak through the side wall between the mounting frame and the filter chamber 301. This allows the ultrafiltration membrane 302 to better ultrafilter the water entering the filter chamber 301.

[0046] The sliding groove 402 is T-shaped, which allows the sliding plate 306 to be slidably installed within the sliding groove 402. Specifically, the sliding plate 306 is adapted to the sliding groove 402, so that the side wall of the sliding plate 306 can slide against the corresponding side wall of the sliding groove 402, so that the sliding plate 306 will not shake within the sliding groove 402, and the placement block 400 will not shake within the filter chamber 301, thereby allowing the ultrafiltration membrane 302 to be better placed within the filter chamber 301.

[0047] The notch 501 allows the upper end of the sliding plate 306 to extend into the chamber. The sliding plate 306 is L-shaped, allowing the connecting assembly to move to a position below the sliding plate 306 so that the lower side of the sliding plate 306 can abut against the upper side of the connecting assembly. This allows the connecting assembly to connect with the sliding plate 306, enabling the cover 201 to drive the sliding plate 306 to slide the ultrafiltration membrane 302 out of the filtration chamber 301 for easy replacement of the ultrafiltration membrane 302.

[0048] Combination Figures 5-7 As shown, in this embodiment, the locking assembly includes inclined blocks 603 disposed opposite each other in the cavity. A locking rod 600 is provided on one side wall of the inclined block 603. An abutment plate is also disposed opposite each other in the cavity. The locking rod 600 passes through the abutment plate. A first spring 602 is sleeved on the locking rod 600 located between the abutment plate and the inclined block 603. The first spring 602 is used to drive the inclined block 603 to reset, so that the locking rod 600 disengages from the lock hole 304. The locking assembly also includes a driving member disposed in the cavity. The driving member is used to drive the two inclined blocks 603 to move away from each other, so that the locking rod 600 is inserted into the corresponding lock hole 304.

[0049] In actual use, the cover 201 is placed over the opening of the filter chamber 301 so that the fixing plate 303 can be inserted into the chamber through the slot 500. The driving component can drive the two inclined blocks 603 away from each other, thereby enabling the inclined blocks 603 to move the locking rod 600 and compress the first spring 602, so that the locking rod 600 can be inserted into the lock hole 304 to fix the fixing block.

[0050] In actual use, one end of the first spring 602 abuts against one side wall of the abutment plate, and the other end abuts against one side wall of the inclined block 603. When it is necessary to release the locking assembly from fixing the fixed plate 303, the driving component stops driving the two inclined blocks 603 away from each other, so that under the action of the first spring 602, the two first springs 602 can push the corresponding inclined blocks 603 closer to each other, thereby enabling the two inclined blocks 603 to drive the corresponding locking rod 600 to disengage from the locking rod 600, that is, to release the locking of the fixed plate 303, so that the cover 201 can be removed from the filter box.

[0051] The bottom wall of the chamber is provided with a T-shaped groove, and the bottom wall of the inclined block 603 is provided with a slider 609 that can extend into the groove and is adapted to the groove. Through the setting of the groove and the slider 609, the inclined block 603 can be slidably installed in the groove.

[0052] Specifically, the groove and the slider 609 are adapted to each other, so that the side wall of the slider 609 can slide against the corresponding side wall of the groove, thereby preventing the slider 609 from shaking in the groove, and thus allowing the inclined block 603 to slide relatively stably in the cavity.

[0053] The locking rod 600 has a limiting groove on its outer side wall along its axial direction, and the abutment plate has a limiting block that slides into the limiting groove. By setting the limiting groove and the limiting block, the locking rod 600 can be better prevented from disengaging from the abutment plate, thus affecting the use of the locking assembly.

[0054] Combination Figures 6-7 As shown, in this embodiment, the side of the cover 201 is provided with the drive box 202, and the drive box 202 is provided with a drive cavity 700 that communicates with the chamber; the drive component includes a drive block 610 provided in the chamber, a first inclined surface is provided on the other side wall of the inclined block 603, a second inclined surface adapted to the first inclined surface is provided on the opposite side wall of the drive block 610, a drive rod 607 extending into the drive cavity 700 is provided on the upper side wall of the drive block 610, the drive rod 607 extends through the drive cavity 700, and a second spring 608 is provided on the drive rod 607 located in the drive cavity 700, the second spring 608 is used to push the drive downward;

[0055] In actual use, in the initial state, the second spring 608 pushes the drive block 610 downward, allowing the second inclined surface to slide against the first inclined surface. The second spring 608 continues to push the drive block 610 downward, allowing the second inclined surface to slide and press against the first inclined surface. This causes the first inclined surface to drive the inclined block 603 to move the locking rod 600 and compress the first spring 602, allowing the locking rod 600 to be inserted into the locking hole 304, thus fixing the cover 201 to the filter tank 300. Simultaneously, the drive rod 607 is lifted, causing the drive rod 607 to move the drive block 610 upward, allowing the second inclined surface to slide away from the first inclined surface. At this time, under the action of the first spring 602, the first spring 602 can drive the inclined block 603 to reset, allowing the locking rod 600 to disengage from the locking hole 304, thereby releasing the cover 201 from the filter tank 300.

[0056] The upper end of the second spring 608 abuts against the upper side wall of the drive cavity 700, and the lower end abuts against the upper side wall of the drive block 610, so that the second spring 608 can always push the drive block 610 to move down, so that the drive block 610 can always drive the two locking rods 600 to insert into the corresponding locking holes 304, thereby making the cover 201 always fixed on the filter water tank 300.

[0057] In actual use, a slot is provided on the outer side wall of the drive rod 607 along its axial direction, and a block is provided on the side wall of the drive cavity 700 that extends into the slot; the slot and the block are adapted to each other, so that the side wall of the block can slide against the side wall of the slot, thereby preventing the drive rod 607 from rotating, and thus ensuring that the second inclined surface is always in contact with the first inclined surface.

[0058] In order to facilitate the operator to lift the drive rod 607, in this embodiment, a lifting post 203 is provided at the end of the extended end of the drive rod 607. The lifting post 203 facilitates the operator to lift the drive rod 607.

[0059] The fixing plate 303 is adapted to the slot 500, so that the side wall of the fixing plate 303 can slide and fit against the corresponding side wall of the slot 500, thereby preventing the cover 201 from shaking on the filter water tank 300, so that the locking rod 600 can be aligned with the locking hole 304, and at the same time, the cover 201 can be stably installed on the filter water tank 300.

[0060] Combination Figures 6-8As shown, in this embodiment, the drive block 610 has a cavity 702; the connecting assembly includes a square cylinder 606 disposed opposite to each other in the cavity, a slidable square post 605 disposed in the square cylinder 606, and a rotatable threaded rod 604 disposed in the square cylinder 606, one end of the threaded rod 604 being threaded into the square post 605, and the other end of the threaded rod 604 being inserted into the cavity 702; the connecting assembly also includes a power component disposed in the cavity 702, which is used to drive the two threaded rods 604 to rotate synchronously.

[0061] In practical use, this embodiment uses a power component to drive two threaded rods 604 to rotate synchronously. Since the square column 605 is adapted to the square cylinder 606, the side wall of the square column 605 can slide against the corresponding side wall of the square cylinder 606, thus limiting the square column 605. This allows the rotation of the threaded rods 604 to drive the square column 605 to extend and retract within the square cylinder 606, allowing the square column 605 to extend into the square cylinder 606 and onto the lower side of the sliding plate 306. The lower side of the sliding plate 306 then abuts against the upper side of the square column 605. When the box cover 201 is removed by moving upwards, the square column 605 drives the sliding plate 306 to move the placement block 400 upwards, thereby allowing the placement block 400 to move the ultrafiltration membrane 302 upwards and slide it out of the filter chamber 301 for replacement.

[0062] In actual use, the power component enables the two threaded rods 604 to rotate synchronously, which in turn drives the square column 605 to extend and retract within the square cylinder 606. This allows the square column 605 to retract into the square cylinder 606, thereby releasing the overlap of the sliding plate 306 on the square column 605. When the cover 201 is removed, the square column 605 will not drive the sliding plate 306 to move the placement block 400 upward, so that water can be added to the filter water tank 300 and the ultrafiltration membrane 302 can perform ultrafiltration.

[0063] Among them, the sliding plate 306 has an elongated groove along its height direction on the opposite side wall, and a limiting post 403 extending into the elongated groove is provided in the sliding groove 402. By setting the elongated groove and the limiting post 403, the sliding plate 306 can be prevented from detaching from the sliding groove 402.

[0064] The sliding plate 306 is adapted to the notch 501, so that the side wall of the sliding plate 306 can slide against the corresponding side wall of the notch 501, thereby preventing the sliding plate 306 from shaking in the notch 501, and thus ensuring that the sliding plate 306 can always be in contact with the square column 605, thereby better preventing the sliding plate 306 from detaching from the square column 605.

[0065] The other end of the threaded rod 604 is rotatably mounted on the corresponding side wall of the cavity 702 via a bearing, thereby enabling the threaded rod 604 to be rotatably mounted.

[0066] Combination Figure 8 As shown, in this embodiment, the power component includes a rotating rod 701 that extends through the drive rod 607 into the cavity 702. The lower end of the rotating rod 701 is provided with a first bevel gear 703. The other end of the threaded rod 604 located in the cavity 702 is provided with a second bevel gear 704 that meshes with the first bevel gear 703. The rotation of the first bevel gear 703 is used to drive the two second bevel gears 704 to rotate synchronously.

[0067] In actual use, this embodiment drives the rotating rod 701 to rotate, which in turn drives the first bevel gear 703 to rotate. This, in turn, drives the two second bevel gears 704 to rotate synchronously, which in turn drives the corresponding threaded rod 604 to rotate, so that the square column 605 can extend and retract within the square tube 606.

[0068] In actual use, the rotating rod 701 is rotatably mounted on the drive rod 607 via a bearing, thereby enabling the rotating rod 701 to be rotatably mounted.

[0069] The upper end of the rotating rod 701 extends out of the driving rod 607, and a nut 204 is provided at the end of the extended end. The nut 204 facilitates the operator to drive the rotating rod 701 to rotate.

[0070] In practical use, when water needs to be added to the humidifier, the first cover 103 is removed from the lower housing 100. Then, the drive rod 607 is lifted, causing the drive rod 607 to move the drive block 610 upwards. Under the action of the first spring 602, the first spring 602 drives the inclined block 603 to reset, allowing the locking rod 600 to disengage from the locking hole 304, thus releasing the cover 201 from the filter water tank 300. Water is added to the filter chamber 301 and filtered through the ultrafiltration membrane 302. The filtered water flows into the atomizing water tank 200. The cover 201 is then fixed to the filter water tank 300, and the first cover is then removed. 103 is installed on the lower housing 100. The atomizing assembly vibrates the water entering the atomizing channel 205, causing it to atomize. When the ultrafiltration membrane 302 needs to be replaced, the drive rotating rod 701 is rotated, which drives the first bevel gear 703 to drive the two second bevel gears 704 to rotate synchronously. The two second bevel gears 704 drive the corresponding threaded rod 604 to rotate, so that the square column 605 can extend out of the square cylinder 606. The square column 605 can abut against the square cylinder 606, so that the upper moving box cover 201 can drive the sliding plate 306 to drive the ultrafiltration membrane 302 for replacement.

[0071] 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.
