Description

Technical Field

[0001] This utility model relates to the field of aromatherapy equipment, and in particular to a liquid replenishment mechanism and aromatherapy equipment. Background Technology

[0002] The liquid replenishment mechanism usually works by pressing a pump to extract liquid from the container and spray the extracted liquid onto the absorbent block, allowing the absorbent block to absorb the aromatherapy essential oil liquid and achieve a fragrance diffusion effect.

[0003] Existing aromatherapy devices with liquid replenishment mechanisms typically feature upward-facing spray nozzles with a shielding structure above them. This shielding structure deflects the upward-sprayed liquid onto a liquid-absorbing block located around the nozzle, completing the spraying action. This method inevitably causes liquid to fall vertically back into the nozzle, leading to blockage. Furthermore, because the upward-sprayed liquid is obstructed, it splashes downwards, with some liquid adhering to the shielding cover and some spilling outside the product, resulting in significant liquid loss. Summary of the Invention

[0004] This invention provides a liquid replenishment mechanism and aromatherapy device, aiming to solve the problems of nozzle blockage and large liquid loss caused by upward spraying in existing liquid replenishment mechanisms.

[0005] According to an embodiment of this application, a liquid replenishment mechanism is provided, including a pressing component and a fragrance dispersing component. The pressing component is inserted into the fragrance dispersing component, and the pressing component drives the fragrance dispersing component to move. The pressing component includes a pressing cover and a liquid extraction component, which are respectively disposed at both ends of the fragrance dispersing component. One end of the liquid extraction component is inserted into the fragrance dispersing component, and the other end extracts liquid. A flow channel is provided inside the pressing cover, and a spray nozzle is opened on the side of the pressing cover facing the fragrance dispersing component. One end of the flow channel is connected to the fragrance dispersing component and the liquid extraction component in sequence, and the other end is connected to the spray nozzle.

[0006] Preferably, the fragrance dispersing component includes a movable disc and a liquid replenishment component. One end of the movable disc is inserted into the press cover and communicates with the flow channel, and the other end of the movable disc is inserted into the liquid extraction component and communicates with the flow channel. The liquid replenishment component is positioned on the movable disc near the spray nozzle.

[0007] Preferably, it further includes a top shell, which is circumferentially disposed on the outer periphery of the fragrance dispersing component, and the liquid extraction component is positioned inside the top shell.

[0008] Preferably, a fixing component is positioned inside the top shell, and the pressing component further includes a limiting member. The fragrance dispersing component, the fixing component, and the limiting member are arranged sequentially in the height direction. The limiting member passes through the fixing component and is fixedly connected to the fragrance dispersing component. The fragrance dispersing component drives the limiting member to move in the area located between the fixing component and the top shell.

[0009] Preferably, the side of the liquid extraction component is provided with a raised boss, the top shell is provided with a receiving groove near the boss, the boss is placed in the receiving groove, and the fixing component pre-tightens the boss in the receiving groove.

[0010] Preferably, the movable disk has a return port on the outer periphery of the corresponding pressing axis; the movable disk is inclined away from the liquid to be replenished on the surface on which the liquid to be replenished is placed, with the outer periphery of the movable disk facing the return port.

[0011] Preferably, a first through hole extending outward is provided on one side of the receiving groove, and there is a gap between the first through hole and the side of the boss.

[0012] This utility model also provides an aromatherapy device, including any of the above-mentioned liquid replenishment mechanisms, and further including a liquid storage component. The liquid storage component has a bottle opening on the side near the pressing component, the liquid extraction component passes through the bottle opening, and the liquid extraction component is eccentrically arranged relative to the bottle opening.

[0013] Preferably, the pressing axis of the pressing cap is eccentrically positioned relative to the surface of the fragrance dispersing component; the pressing axis of the pressing cap and the liquid extraction component are aligned in a straight line.

[0014] Preferably, it further includes a bottom shell, which is sleeved on the outer periphery of the liquid storage assembly, and the bottom shell is inserted and fixed to the top shell.

[0015] Compared with the prior art, the liquid replenishment mechanism and aromatherapy device provided by this utility model have the following beneficial effects:

[0016] 1. By setting a flow channel inside the press cap and aligning the spray nozzle with the fragrance dispersing component, the liquid drawn by the pump is guided by the flow channel and the spray nozzle and then sprayed directly downwards onto the fragrance dispersing component. This reduces the free fall of the liquid and avoids the problem of liquid splashing caused by upward spray obstruction, thereby improving the efficiency of liquid spraying and reducing unnecessary liquid loss.

[0017] 2. By placing the limiting component between the liquid collection tray and the top shell, the limiting component for movement does not need to be set with an additional limiting structure. It can be directly embedded between the fixed component and the top shell, making the liquid replenishment mechanism of this product have a smaller height and a simpler internal structure.

[0018] 3. By setting the liquid extraction component off-center relative to the bottle opening, the pressing position of the press cap is also off-center. This results in a larger spray area for the liquid to be replenished when the spray nozzle on one side of the press cap faces it. In other words, a single flow channel can spray a larger area of ​​the liquid to be replenished. There is no need to set multiple spray nozzles at multiple circumferential angles on the surface of the press cap, making the structure of the press cap simpler. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0036] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0037] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0038] Please combine Figure 1 , Figure 2 and Figure 3 The first embodiment of this utility model discloses a liquid replenishment mechanism, including a pressing component 1, a fragrance dispersing component 2, a fixing component 3, and a top shell 4. The top shell 4 surrounds the outer periphery of the pressing component 1, the fragrance dispersing component 2, and the fixing component 3. The pressing component 1, the fragrance dispersing component 2, and the fixing component 3 are arranged sequentially in the height direction. One end of the pressing component 1 extends to the top of the top shell 4.

[0039] The pressing component 1 drives the fragrance dispersing component 2 to move synchronously, and the fixing component 3 is fixed inside the top shell 4. The pressing component 1 is used to move by the user's pressing action to achieve the effect of extracting liquid, and the liquid extracted by the pressing component 1 is guided onto the fragrance dispersing component 2.

[0040] Please combine Figure 2 and Figure 3The pressing assembly 1 includes a pressing cover 11, a liquid extraction component 12, and a limiting component 13. The pressing cover 11 and the liquid extraction component 12 are respectively disposed at both ends of the fragrance dispersing assembly 2. One end of the liquid extraction component 12 is inserted into the fragrance dispersing assembly, and the other end extracts liquid. The limiting component 13 is disposed between the top shell 4 and the fixing assembly 3. The limiting component 13 is fixedly connected to the fragrance dispersing assembly 2, and the limiting component 13 is used to limit the movement stroke of the pressing cover 11.

[0041] Understandable, such as Figure 5 As shown, the pumping component 12 is a common push-button pump, a standard component in portable liquid pumping devices. It contains a spring 300. When the user presses one end, the flexible tube at the other end, which is submerged in liquid, draws liquid towards the pressed end. The spring 300 then returns the pressed end to its original position. Simultaneously, the pumping component 12 contains steel balls to prevent backflow of liquid by sealing the liquid tube 122 when not being pressed. Since the push-button pump is an existing component, the specific internal structure of the pumping component 12 will not be described in detail.

[0042] It is understood that the liquid extraction component 12 itself has a spring 300, that is, the liquid extraction component 12 itself has elastic restoring force. Therefore, the connected pressing cover 11 can achieve elastic restoring with the help of the liquid extraction component 12. In the liquid replenishment mechanism of this product, the pressing cover 11 does not need to be equipped with additional elastic components such as springs. It only needs to be connected to the liquid extraction component 12 to achieve elastic restoring, which simplifies the internal structure.

[0043] The press cover 11 has a flow channel 111 inside. The press cover 11 has a spray nozzle 112 on the side facing the fragrance dispersing component 2. One end of the flow channel 111 is connected to the fragrance dispersing component 2 and the liquid extraction component 12 in sequence, and the other end is connected to the spray nozzle 112, so that the liquid extracted by the liquid extraction component 12 passes through the fragrance dispersing component 2 and enters the flow channel 111, and is sprayed directly onto the surface of the fragrance dispersing component 2 through the spray nozzle 112.

[0044] It is understood that the number of the spray nozzles 112 can be one, two, or more.

[0045] Specifically, such as Figure 3 As shown, the fragrance dispersing component 2 includes a movable disc 21 and a liquid replenishment component 22, the liquid replenishment component 22 being positioned on the side of the movable disc 21 near the pressing cover 11. The pressing cover 11 and the liquid extraction component 12 are respectively disposed at both ends of the movable disc 21, the pressing cover 11, the liquid extraction component 12 and the movable disc 21 are inserted and fixed, and the movable disc 21 has a channel inside the part that is inserted with the pressing cover 11 and the liquid extraction component 12, so that the flow channel 111, the movable disc 21 and the liquid extraction component 12 are connected.

[0046] It is understood that in this embodiment, the liquid to be replenished component 22 is made of PE cotton material, which is used to absorb the extracted aromatherapy liquid (or aromatherapy essential oil).

[0047] like Figure 3 As shown, the flow channel 111 is L-shaped, and the bent pipe makes the spray nozzle 112 directly face the liquid to be replenished component 22 below, forming a downward spraying direction.

[0048] It is understood that in this embodiment, by setting a flow channel 111 inside the press cover 11 and setting the spray nozzle 112 towards the fragrance dispersing component 2, the liquid drawn by the liquid extraction component 12 is sprayed directly downwards onto the fragrance dispersing component 2 after being guided by the flow channel 111 and the spray nozzle 112. This reduces the process of the liquid falling freely and avoids the problem of liquid splashing caused by the upward spray blockage, thereby improving the efficiency of liquid spraying and reducing unnecessary liquid loss.

[0049] Please combine Figure 2 , Figure 3 and Figure 4 The fixing component 3 includes a liquid collection tray 31, which is located at the bottom of the movable tray 21 and is fixedly connected to the top shell 4. The top shell 4 has a connecting part 41 near the liquid extraction component 12, which is used to connect to the opening of a container such as a bottle neck. The end of the liquid extraction component 12 used to extract liquid extends through the liquid collection tray 31 and the connecting part 41 to the lower end.

[0050] It is understood that the movable disk 21 is provided with a return port 211, which is used to discharge liquid that cannot be completely absorbed by the liquid replenishing component 22 downward through the return port 211. The liquid collection tray 31 located below the movable disk 21 collects the returned liquid.

[0051] The limiting member 13 is disposed between the connecting part 41 and the liquid collection tray 31, and one side of the limiting member 13 passes through the liquid collection tray 31 and is fixedly connected to the movable tray 21. When the limiting member 13 moves, the connecting part 41 and the liquid collection tray 31 serve as limiting structures at both ends of the limiting member 13.

[0052] It is understood that the limiting member 13 is provided with multiple extension columns 100, and the liquid collection plate 31 is provided with a sleeve 200 at the position of the corresponding extension column 100. The extension column 100 slides in the sleeve 200. The extension column 100 passes through the sleeve 200 and is fixedly connected to the bottom of the moving plate 21. Specifically, it can be fixed with bolts or pre-tightened with buckles.

[0053] It is understood that in this embodiment, the limiting member 13 is disposed between the liquid collection tray 31 and the top shell 4, so that the limiting member 13 for movement does not need to be provided with an additional limiting structure, and can be directly embedded between the fixing component 3 and the top shell 4, so that the liquid replenishment mechanism of this product has a smaller height and a simpler internal structure.

[0054] It is understood that in this embodiment, the return port 211 on the moving disk 21 is located on the outer periphery of the pressing axis of the pressing cover 11, and the moving disk 21 is placed on the surface where the liquid to be replenished 22 is placed. The outer periphery of the moving disk 21 is inclined away from the liquid to be replenished 22 in the direction of the return port 211, that is, a funnel-shaped structure is formed with the return port 211 as the center, so that the liquid to be replenished 22 forms a gap in the area corresponding to the return port 211, which facilitates the downward return of liquid.

[0055] Please continue to combine Figure 3 and Figure 4 The connecting part 41 has a first through hole 411, and the liquid collecting tray 31 has a second through hole 311 at the position corresponding to the first through hole 411. The first through hole 411 is located within the range of the second through hole 311. When the liquid in the return port 211 flows downward back into the liquid collecting tray 31, the liquid continues to flow back. The liquid then passes through the second through hole 311 and the first through hole 411 in sequence, and flows back into the connected container from the position of the connecting part 41.

[0056] It is understood that in this embodiment, the first through hole 411 is the only open hole structure connecting the connecting part 41 to the external container. The first through hole 411 serves as a hole for liquid reflux and also acts as a vent to balance the pressure inside the container. When the user drives the liquid pumping component 12 to work, air enters through the first through hole 411 under atmospheric pressure, forming a power source to drive the reflux liquid back into the container, which can accelerate the liquid reflux. At the same time, since there is no need to set up an additional gas pipeline to balance the pressure inside the container, if the liquid replenishment mechanism of this application is accidentally tilted or inverted during use of the connected container, combined with the viscosity of the aromatherapy essential oil liquid, the rate at which the liquid in the container leaks out through the first through hole 411 will be greatly reduced. This will give the user sufficient reaction time to straighten the product, greatly reducing the probability of leakage during the use of this product.

[0057] It is understood that in this embodiment, the liquid extraction component 12 includes a liquid tube 122 for contacting and extracting liquid. The aperture size of the first through hole 411 is smaller than the inner diameter of the liquid tube 122. This allows the smaller aperture of the first through hole 411 to have greater suction and gas flow rate when the user drives the liquid extraction component 12, based on the principle of atmospheric pressure balance, further increasing the efficiency of liquid reflux. Simultaneously, the smaller aperture of the first through hole 411, combined with the viscosity of the aromatherapy essential oil liquid, reduces the rate of liquid leakage from the container in case of accidental spillage or inversion, giving the user more reaction time.

[0058] Please continue to combine Figure 3 and Figure 4The liquid extraction component 12 has a raised boss 121 on its side. The connecting part 41 has a receiving groove 42 near the boss 121. The boss 121 is placed in the receiving groove 42. The fixing component 3 pre-tightens the boss 121 in the receiving groove 42.

[0059] It is understood that in this embodiment, the receiving groove 42 is connected to the first through hole 411, forming an integral opening structure, such as... Figure 2 As shown, the first through hole 411 is provided on the side of the receiving groove 42, that is, the first through hole 411 is a hole structure extending from the side of the receiving groove 42, and the receiving groove 42 and the first through hole 41 are connected in this area. When the boss 121 of the liquid pumping member 12 is placed in the receiving groove 42, the gap between the edge of the boss 121 and the first through hole 411 forms the pore size of the first through hole 411.

[0060] It is understood that in other embodiments, the receiving groove 42 and the first through hole 411 can also be provided separately, that is, in a non-connected state. For example, the connecting part 41 is divided into two openings, one of which is opened to form the receiving groove 42 for positioning and passing through the liquid extraction member 12, and the other is opened to form the first through hole 411. The two structures and functions do not affect each other.

[0061] Please continue to combine Figure 2 , Figure 3 and Figure 4 The fixing component 3 further includes a silicone element 32, which is disposed between the top shell 4 and the liquid collection tray 31. The silicone element 32 has a third through hole 321, which is located within the range of the second through hole 311. Figure 4 As shown, the silicone part 32 is located between the connecting part 41 and the liquid collection tray 31. The liquid collection tray 31 pre-tightens the silicone part 32 to the surface of the connecting part 41, and the silicone part 32 pre-tightens the boss 121 in the receiving groove 42 at the edge of the third through hole 321, forming the second through hole 311, the third through hole 321 and the first through hole 411 arranged in sequence in the height direction and fastened in contact.

[0062] It is understandable that by using the soft material silicone part 32, the second through hole 311, the third through hole 321, and the first through hole 411, which serve as the reflux area, are sealed by the silicone part 32, thus preventing liquid leakage caused by the rigid fastening between the connection part 41 and the liquid collection tray 31.

[0063] Understandable, such as Figure 2 As shown, the second through hole 311 and the third through hole 321 are configured in a "teardrop" shape to match the opening size of the receiving groove 42 and the first through hole 411.

[0064] Please continue to combine Figure 3 and Figure 4 If the second through hole 311, the third through hole 321, and the first through hole 411 form a stepped structure in the height direction, then the surface of the liquid collecting plate 31 can be set as an inclined surface. Specifically, it can be a funnel-shaped inclined surface that gradually descends from the outer periphery of the liquid collecting plate 31 towards the second through hole 311, guiding the liquid to flow towards the second through hole 311. At this time, the stepped structure formed by the second through hole 311, the third through hole 321, and the first through hole 411 can further guide the liquid to flow towards the first through hole 411.

[0065] It is understood that in this embodiment, the size of the first through hole 411 is much smaller than that of the second through hole 311 and the third through hole 321. The second through hole 311 and the third through hole 321, together with the top surface of the boss 121 of the liquid pumping member 12, can form a pit for accumulating liquid. The first through hole 411 can quickly pump the liquid back from this area under atmospheric pressure.

[0066] It is understood that in this embodiment, since the second through hole 311, the third through hole 321, and the first through hole 411 are arranged sequentially in the height direction and form a stepped structure, the first through hole 411 serves as the last hole for liquid reflux. The stacking of the three through hole structures increases the height (or length) of the liquid reflux channel. During the operation of the liquid extraction component 12, the first through hole 411 serves as the power source for liquid reflux. The higher and longer liquid reflux channel has a three-dimensional effect. Compared with the existing reflux structure that simply opens holes on the bottom of the plate, the liquid reflux channel of this solution can prevent the liquid from forming a film at the inlet, especially for liquids with high viscosity such as aromatherapy essential oils, so as to ensure that more liquid can be refluxed each time the liquid extraction component 12 works, thereby further improving the efficiency of liquid reflux.

[0067] It is understood that in this embodiment, the return port 211, the second through hole 311, the third through hole 321 and the first through hole 411 provided on the moving disk 21 are arranged sequentially and closely fitted in the height direction. The liquid replenishment mechanism of this product forms a two-stage return layer, which has a simpler internal structure and fewer return layers, reduces the accumulation of liquid inside the product, makes it easier for the liquid to return, and improves the liquid return efficiency.

[0068] Please combine Figure 2 , Figure 3 , Figure 5 and Figure 6 The second embodiment of this utility model provides an aromatherapy device 5, which includes the liquid replenishment mechanism provided in the first embodiment, and further includes a liquid storage component 6 and a bottom shell 7. The liquid storage component 6 includes an aromatherapy bottle 61, and the bottom shell 7 surrounds the outer periphery of the aromatherapy bottle 61. The bottom shell 7 is fixedly connected to the top shell 4, specifically by a snap-fit ​​connection or a threaded connection. The first through hole 411 and the second through hole 311 are opened within the range of the bottle mouth 62.

[0069] The mouth 62 of the aromatherapy bottle 61 is inserted into the end of the connecting part 41 away from the press cap 11, and one end of the liquid extraction member 12 passes through the mouth 62 and enters the aromatherapy bottle 61. The liquid extraction member 12 is eccentrically positioned relative to the mouth 62, that is, the liquid extraction member 12 is positioned close to an inner surface of the mouth 62, so that the pressing axis of the press cap 11 is eccentrically positioned relative to the surface of the fragrance dispersing component 2.

[0070] It is understandable that, based on the pressing principle, the pressing axis of the pressing cover 11 and the pressing movement direction of the liquid extraction component 12 are in a straight line. The eccentric setting of the liquid extraction component 12 makes the pressing position of the pressing cover 11 also eccentric. Therefore, the liquid nozzle 112 on one side of the pressing cover faces the liquid-replenishing component 22 with a larger spray area. That is, a single flow channel 111 can spray a larger area of ​​the liquid-replenishing component 22, and there is no need to set multiple circumferential angles of the liquid nozzle 112 on the surface of the pressing cover 11.

[0071] Alternatively, in other embodiments, the liquid extraction component 12 may be positioned at the axial position of the bottle opening 62, and the liquid spraying nozzle 112 may be positioned at multiple circumferential angle positions of the pressing cap 11 to achieve simultaneous spraying in multiple areas.

[0072] It is understood that in this embodiment, a waterproof rubber ring is provided at the position where the connecting part 41 contacts the top of the bottle mouth 62.

[0073] Compared with the prior art, the liquid replenishment mechanism and aromatherapy device provided by this utility model have the following beneficial effects:

[0074] 1. By setting a flow channel inside the press cap and aligning the spray nozzle with the fragrance dispersing component, the liquid drawn by the pump is guided by the flow channel and the spray nozzle and then sprayed directly downwards onto the fragrance dispersing component. This reduces the free fall of the liquid and avoids the problem of liquid splashing caused by upward spray obstruction, thereby improving the efficiency of liquid spraying and reducing unnecessary liquid loss.

[0075] 2. By placing the limiting component between the liquid collection tray and the top shell, the limiting component for movement does not need to be set with an additional limiting structure. It can be directly embedded between the fixed component and the top shell, making the liquid replenishment mechanism of this product have a smaller height and a simpler internal structure.

[0076] 3. By setting the liquid extraction component off-center relative to the bottle opening, the pressing position of the press cap is also off-center. This results in a larger spray area for the liquid to be replenished when the spray nozzle on one side of the press cap faces it. In other words, a single flow channel can spray a larger area of ​​the liquid to be replenished. There is no need to set multiple spray nozzles at multiple circumferential angles on the surface of the press cap, making the structure of the press cap simpler.

[0077] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
