Description

Technical Field

[0001] The utility model relates to a double-spray button which can be used to spray solutions through two outlets respectively. Background Art

[0002] In the prior art, a dual-spray button is a button with two material spray outlets. For example, publication number CN116943899A discloses a rotatable and adjustable dual-nozzle actuator, which includes a mounting seat, a nozzle seat, a rotary cover and a valve device. When in use, the rotary cover is rotated to drive the valve device to rotate, thereby selectively connecting the first nozzle or the second nozzle on the nozzle seat to the liquid inlet channel.

[0003] In order to facilitate the user to control the rotation angle of the rotary cap, the patent also provides a paddle device that emits a sound prompt when the rotary cap is rotated into position so that the valve device controls the liquid inlet channel to be connected with the first nozzle or the second nozzle. The sound emitted by the paddle device is used to determine whether the rotary cap is screwed to the predetermined position.

[0004] However, in this patent, when the rotary cap is rotated, the paddle block on the rotary cap needs to squeeze and pass over the protrusion on the nozzle seat to make a sound, that is, at least one of the paddle block and the protrusion needs to undergo elastic deformation, which causes the paddle device to fail due to shape deformation after long-term use, making it impossible for the user to promptly and clearly understand whether the rotary cap is in a usable position, thereby causing inconvenience in use.

Those skilled in the art can understand the specific meanings of the above terms in this utility model based on the overall concept of this utility model and the specific context of this solution.

[0040] Example 1

[0041] A double spray button, such as Figure 1-3 As shown, it includes a button body 1, a button cover 2 and a rotor 3.

[0042] like Figure 4-8 As shown, the button body 1 is generally cylindrical and includes an outer shell 11 and a material inlet channel 12 that is generally coaxially arranged at the center of the outer shell 11. In addition, two ejection ports 13 are provided on the circumferential side wall of the outer shell 11. Both ejection ports 13 are connected to a material ejection channel 14, and both material ejection channels 14 are in communication with the material inlet channel 12. It is easy to understand that both the material inlet channel 12 and the channel 14 are hollow tubular structures so that the material can flow from the material inlet channel 12 to the ejection port 13. Typically, the material inlet channel 12 is formed by a material inlet pipe structure, and the two material ejection channels 14 are formed by a material ejection pipe structure, and the outer shell 11, the material inlet pipe, and the two material ejection pipes are integrally formed and manufactured.

[0043] like Figure 9-11 As shown, the rotor 3 is installed in the material inlet channel 12. The rotor 3 also has a flow channel for the material to flow, and the outer wall of the rotor 3 is adapted to the inner wall of the material inlet channel 12 to prevent the material from leaking from the gap between the two, so that the material can only flow through the flow channel in the rotor 3. The flow channel in the rotor 3 has flow channel openings formed at both ends on the bottom end and the circumferential side wall of the rotor 3. The flow channel opening formed at the bottom end of the rotor 3 is used to receive the material delivered from the material inlet channel 12, and the flow channel opening formed on the circumferential side wall of the rotor 3 (hereinafter referred to as the side hole 31) is used to deliver the material to the material ejection channel 14. The rotor 3 can rotate around its axis within the material inlet channel 12. The connection between the two material ejection channels 14 and the material inlet channel 12 is located on the rotation path of the side hole of the rotor 3. When in use, by rotating the rotor 3, the side hole of the rotor 3 can be aligned with the two material ejection channels 14.

[0044] like Figure 12-14As shown, the button cover 2 is roughly in the shape of a concave shell with a closed top and an open bottom. The button cover 2 mainly includes two parts: a top wall and a circumferential side wall. The button cover 2 is used to cover the button body 1 from both the top surface and the circumferential side surface.

[0045] In this embodiment, the top wall of the button cover 2 is also fixedly connected to the top of the rotor 3. For example, after the rotor 3 is assembled in the material entry channel 2, a portion of the top of the rotor 3 protrudes beyond the top of the material entry channel 12. Accordingly, the top wall of the button cover 2 (located on one side inside the button cover 2) is formed with an annular groove structure 21 that protrudes into the interior of the button cover 2, and the top of the rotor 3 extends into this annular groove structure 21.

[0046] In addition, ribs 22 are formed within the annular groove structure 21. These ribs 22 can be in a straight, cross, T-shaped, or X-shaped configuration, and can be integral or separate. The top surface of the rotor 3 is correspondingly provided with rib grooves 32 that mate with the ribs 22. The interaction between the ribs 22 and the grooves 32 enables the button cover 2 to drive the rotor 3 in circumferential rotation. Alternatively, in other preferred embodiments, the grooves can be formed within the button cover 2 (e.g., within the annular groove structure 21), while the ribs can be positioned on the top of the rotor 3.

[0047] It is easy to understand that in order to reduce the overall size, especially the axial size, this embodiment further configures the top side of the material ejection channel 14 with a ring groove structure 21 for accommodating the ring groove structure 21 and an escape notch 141 for the ring groove structure 21 to rotate within. The bottom end of the ring groove structure 21 can abut against the escape notch 141, so that after pressing the button cover 2, axial pressure is applied to the material ejection channel 14 and the material inlet channel 12 through the ring groove structure 21. Of course, the ring groove structure 21 can also not contact the escape notch 141, and it is only necessary to provide a boss for supporting the rotor 3 within the material inlet channel 12, so that the rotor 3 can directly apply axial pressure to the material inlet channel 12.

[0048] In this embodiment, a structure, such as a snap-fit ​​structure, is provided between the button cover 2 and the button body 1 to prevent axial separation between the two. For example, the annular groove structure 21 on the button cover 2 is configured with a large inner diameter so that the top of the material entry channel 12 can extend into the gap between the annular groove structure 21 and the rotor 3. The snap-fit ​​structure is then positioned between the inner circumferential wall of the annular groove structure 21 and the outer circumferential wall of the material entry channel 12. This snap-fit ​​structure prevents the button cover 2 from axially separating from the material entry channel 12. Furthermore, in the axially downward direction, when the lower end of the rotor 3 contacts the boss on the inner wall of the material entry channel 12, the button cover 2 is prevented from axially moving downward relative to the material entry channel 12.

[0049] Furthermore, a clearance hole 25 is also defined on the circumferential sidewall of the button cover 2. This clearance hole 25 is radially aligned with the side hole 31 on the rotor 3. That is, when the side hole 31 of the rotor 3 is aligned with any material ejection channel 14, the clearance hole 25 faces the corresponding ejection port 13, thereby not interfering with the ejection of the material. The clearance hole 25 can be a through-hole or a notch defined in the circumferential sidewall of the button cover 2. The specific shape is not limited, as long as it can avoid the material ejected from the ejection port 13.

[0050] When in use, first rotate the button cover 2, and the button cover 2 drives the rotor 3 to rotate so that the side hole 31 of the rotor 3 is aligned with one of the material ejection channels 14, and then apply axial downward pressure to the button cover 2, and the pressure will be transmitted to the material entry channel 12. Since the material entry channel 12 is connected to the outer shell 11 only through the two material ejection channels 14, when the material entry channel 12 overcomes the supporting force used to maintain its stable position, it can move axially downward, and then apply pressure to the pump (not shown in the figure) extended into the material entry channel 12, so that the pump is pressurized and works. When the pressing force on the button cover 2 is released, the button cover 2 will reset. This reciprocating process will repeat many times, and the pump will pump the material into the material entry channel 12, and then the material enters the flow channel of the rotor 3, and then flows into the corresponding material ejection channel 14 through the side hole 31 of the rotor 3, and finally is ejected through the ejection port 13. In this way, in actual use, it is only necessary to make differentiated configurations of the two nozzles 13, for example, setting the two nozzles 13 with different apertures to obtain sprays of different shapes and doses; or installing different nozzles for the two nozzles 13, so as to change the physical state of the material body through different types of nozzles to obtain different types of sprays.

[0051] It is easy to understand that the above-mentioned usage example is limited to the button body 1 being stationary (relative to) the material product container during use. However, in other preferred embodiments, the button body 1 can also be axially movably installed at the neck (or bottle mouth) of the material product container. When axial pressure is applied to the button cover 2, the button body 1 will move axially relative to the material product container, thereby driving the pressing pump fixed at the neck (or bottle mouth) of the material product container to operate, thereby pumping out the material product. In this usage mode, the button body 1 can be made into a rigid structure, thereby eliminating the need for the material inlet channel 12 to undergo axial relative movement with respect to the outer shell 11.

[0052] In this embodiment, in order to ensure that the side holes 31 of the rotor 3 are accurately aligned circumferentially with the two material ejection channels 14, a stop structure 4 is further provided inside the button cover 2. The stop structure 4 rotates as the button cover 2 rotates. Correspondingly, a cooperating limiting structure 5 is provided on the button body 1. The limiting structure 5 is located on the rotation path of the stop structure 4, so that when the stop structure 4 contacts the limiting structure 5, the button cover 2 stops and cannot continue to rotate, and the side hole 31 of the rotor 3 is just opposite to the material ejection channel 14.

[0053] Among them, there are two stop structures 4 and two limiting structures 5, and the circumferential angle between the two limiting structures 5 is roughly equivalent to the circumferential angle between the two material ejection channels 14, and the circumferential angle between the two stop structures 4 is roughly twice the circumferential angle between the two material ejection channels 14.

[0054] In this embodiment, the limiting structure 5 can be formed on the material ejection channel 14. Of course, the limiting structure 5 can also be the material ejection channel 14 itself or formed on the circumferential inner wall of the button body 1. The stopping structure 4 can be formed on the outer wall of the annular groove structure 21. Of course, the stopping structure 4 can also be formed on the top wall of the button cover 2, or the stopping structure 4 can be formed on both the outer wall of the annular groove structure 21 and the inner bottom wall of the button cover 2.

[0055] In this embodiment, the stop structure 4 is preferably a flat plate with its surface parallel to the axis of the button cover 2. Accordingly, a planar contact surface is provided on the material ejection channel 14, thereby enabling the stop structure 4 to form a more stable contact with the material ejection channel 14. Of course, in other preferred embodiments, the stop structure 4 may also have other shapes, and the contact between the stop structure 4 and the material ejection channel 14 may also be point contact, line contact, or curved surface contact.

[0056] Specifically, the positions of the stop mechanism 4 and the limiting structure 5 satisfy the following: Figure 3As shown, in the process of the button cover 2 driving the rotor 3 to rotate (clockwise when looking down at the button cover 2 from a high place), when one of the stop structures 4 (hereinafter referred to as the stop structure A for the sake of convenience) hits the limiting mechanism 5 formed on one of the material ejection channels 14 (hereinafter referred to as the material ejection channel A for the sake of convenience), the side hole 31 of the rotor 3 is just aligned with the other material ejection channel 14 (hereinafter referred to as the material ejection channel B for the sake of convenience). At this time, the button cover 2 cannot continue to rotate in the clockwise direction and can only rotate in the counterclockwise direction. In the process of the button cover 2 driving the rotor 3 to rotate counterclockwise, when the other stop structure 4 (hereinafter referred to as the stop structure B for the sake of convenience) hits the limiting structure 5 formed on the other material ejection channel 14 (i.e., the material ejection channel B), the side hole 31 of the rotor 3 is just aligned with one of the material ejection channels 14 (i.e., the material ejection channel A).

[0057] It is easy to understand that in order to make it easier for the material entry channel 12 to move axially downward relative to the outer shell 11 under pressure, in this embodiment, on the one hand, the two material ejection channels 14 are arranged as close as possible circumferentially, for example, the angle between the two material ejection channels 14 is arranged to be 90 degrees. Of course, in other preferred embodiments, it can also be arranged to other values ​​such as 80 degrees, 70 degrees, or 60 degrees. On the other hand, for the position where the material ejection channel 14 is connected to the outer shell 11, a slit 15 can be provided at the connection, for example, an axial slit 151 and a circumferential slit 152 can be provided. For example, an axial slit 151 can be provided on the side of the ejection port 13, and a circumferential slit 152 can be provided below the ejection port 13. Thus, the provision of the slit 15 can reduce the connection area and size between the material ejection channel 14 and the outer shell 11. Both of these arrangements make it easier for the material entry channel 12 to move axially.

[0058] It is easy to understand that if Figure 4-8 As shown, in order to prevent the structural strength of the outer shell 11 from being reduced due to the setting of the slit 15, in other preferred embodiments, the button body 1 is further configured to include an inner shell 16, the diameter of the inner shell 16 is smaller than the outer shell 11, the inner shell 16 is coaxially arranged inside the outer shell 11, and the lower part of the inner shell 16 is connected to the inner wall of the outer shell 11, for example, an integrally molded connection.

[0059] In addition, at least a portion of the upper portion of the inner shell 16 protrudes from the outer shell 11 , and the ejection port 13 is opened on the protruding portion of the inner shell 16 , so that the ejection port 13 opened on the upper portion of the inner shell 16 will not be blocked by the outer shell 11 .

[0060] The two material ejection channels 14 are arranged inside the inner shell 16 , and the material ejection channels 14 are connected to the inner shell 16 and communicate with the ejection outlet 13 . Accordingly, the slits 15 are all provided on the inner shell 16 .

[0061] With this arrangement, when the button cover 2 is pressed, the material entry channel 12 and the connected material ejection channel 14 can obtain sufficient axial movement space without affecting the structural strength of the button body 1 (the outer shell 11 therein).

[0062] Typically, the circumferential sidewall of the button cover 2 is embedded between the outer housing 11 and the inner housing 16. Furthermore, a cooperating snap-fit ​​structure may be provided between the button cover 2 and the inner housing 16, or between the button cover 2 and the outer housing 11. For details, reference may be made to the snap-fit ​​structures between the button cover 2 and the rotor 3, and between the annular groove structure 21 and the material inlet passage 12. This further restricts the axial relative position of the button cover 2 and the button body 1, preventing the button cover 2 from easily detaching axially from the top side relative to the button body 1.

[0063] Example 2

[0064] It is easy to understand that in order to achieve the above-mentioned stopping effect, the number and position of the stopping structures 4 and the limiting structures 5 are not limited to the above-mentioned solutions, and the following alternatives are also possible:

[0065] Alternative solution: Only one stopping structure 4 is configured and it is also formed on the outer wall of the annular groove structure 21, while two limiting structures 5 are configured. The circumferential angle between the two limiting structures 5 is still roughly equivalent to the circumferential angle between the two material ejection channels 14, and the two limiting structures 5 can also continue to be formed on the two material ejection channels 14.

[0066] The positions of the stop structure 4 and the limiting structure 5 are configured to meet the following requirements: Figure 15 As shown, in the process of the button cover 2 driving the rotor 3 to rotate (counterclockwise when looking down at the button cover 2 from a high place), when the stop structure 4 hits the limiting structure 5 formed on one of the material ejection channels 14 (for the sake of ease of understanding, hereinafter referred to as the material ejection channel A), the side hole 31 of the rotor 3 is just aligned with the material ejection channel 14 (i.e., the material ejection channel A). At this time, the button cover 2 cannot continue to rotate in the counterclockwise direction and can only rotate clockwise; and in the process of the button cover 2 driving the rotor 3 to rotate in the clockwise direction, when the stop structure 4 hits the limiting structure 5 formed on the other material ejection channel 14 (i.e., the material ejection channel B), the side hole 31 of the rotor 3 is just aligned with the material ejection channel 14 (i.e., the material ejection channel B).

[0067] Example 3

[0068] It is easy to understand that in order to achieve the above-mentioned stopping effect, the number and position of the stopping structures 4 and the limiting structures 5 are not limited to the above-mentioned solutions, and the following alternatives are also possible:

[0069] Alternative solution: Two stop structures 4 are configured and both are formed on the outer wall of the annular groove structure 21, while one limiting structure 5 is configured and further formed on one of the material ejection channels 14. The circumferential angle between the two stop structures 4 is still equivalent to the circumferential angle between the two material ejection channels 14.

[0070] The positions of the stop structure 4 and the limiting structure 5 are configured to meet the following requirements: Figure 16 As shown, in the process of the button cover 2 driving the rotor 3 to rotate (counterclockwise when looking down at the button cover 2 from a high place), when one of the stop structures 4 (hereinafter referred to as the stop structure A for the sake of convenience) hits the limiting structure 5 formed on the material ejection channel 14 (hereinafter referred to as the material ejection channel A for the sake of convenience), the side hole 31 of the rotor 3 is just aligned with the material ejection channel 14 (i.e., the material ejection channel A). At this time, the button cover 2 cannot continue to rotate in the counterclockwise direction and can only rotate in the clockwise direction; and in the process of the button cover 2 driving the rotor 3 to rotate in the clockwise direction, when the other stop structure 4 (hereinafter referred to as the stop structure B for the sake of convenience) hits the limiting structure 5 formed on the material ejection channel 14 (i.e., the material ejection channel A), the side hole 31 of the rotor 3 is just aligned with the other material ejection channel 14.

[0071] Example 4

[0072] In the double-spray button disclosed in the above embodiment, it can only be used normally when the side hole 31 of the rotor 3 is circumferentially aligned with the material ejection channel 14. When the side hole 31 of the rotor 3 is circumferentially staggered with the material ejection channel 14, pressing the button cover 2 will not cause the material to be ejected from the ejection port 13. Forcibly pressing the button cover 2 may cause the material to leak at the fitting point between the rotor 3 and the material entry channel 12.

[0073] Therefore, the side hole 31 of the rotor 3 and the material ejection channel 14 need to be circumferentially staggered to prevent the button cover 2 from being pressed.

[0074] In this embodiment, Figure 13 and 14 As shown, a support body 6 is provided in the button cover 2. For example, the support body 6 is formed on the inner side of the circumferential side wall of the button cover 2. Of course, in other preferred embodiments, the support body 6 can also be formed on the top wall of the button cover 2 and located outside the annular groove structure 21. Correspondingly, a notch 7 is provided on the button body 1 for use with the support body 6. For example, the notch 7 is provided at the upper portion of the inner housing 16.

[0075] In this embodiment, Figure 3 and 4 As shown, there are two notches 7, so that when the side holes 31 of the rotor 3 are aligned with the two material ejection channels 14 respectively, the support body 6 is correspondingly aligned with the two notches 7 respectively, that is, the circumferential angle between the two notches 7 is the same as the circumferential angle between the two material ejection channels 14.

[0076] During use, when the side hole 31 of the rotor 3 is aligned with any of the material ejection channels 14, the support body 6 is also aligned with one of the notches 7. At this time, after pressing the button cover 2, the support body 6 can fall into the corresponding notch 7, that is, the button cover 2 will move downward relative to the inner housing 16, thereby smoothly driving the material entering the channel 12 to move axially downward. When the side hole 31 of the rotor 3 is misaligned with the material ejection channel 14, the support body 6 is also misaligned with the notch 7. At this time, when pressing the button cover 2, the support body 6 is blocked by the upper edge of the inner housing 16, resulting in the button cover 2 being unable to be pressed down, and thus preventing the material entering the channel 12 from moving axially downward.

[0077] It is easy to understand that this embodiment further configures the support body 6 and the avoidance hole 25 on the button cover 2 to be arranged in a central symmetrical shape. This arrangement allows the downward stroke of the support body 6 in the notch 7 to be more converted into the axial downward movement stroke of the material body entering the channel 12, thereby ensuring effective pressing of the pump.

[0078] Example 5

[0079] The inner wall of the material inlet channel 12 is provided with a circle of bosses 17 for supporting the bottom end of the rotor 3. With this arrangement, when the button cover 2 is pressed, the bottom end of the rotor 3 will press on the top surface of the boss 17, thereby preventing the side hole 31 of the rotor 3 from axially displacing relative to the material inlet channel 12, thereby avoiding the side hole 31 of the rotor 3 and the material ejection channel 14 from being misaligned in the axial direction.

[0080] It is easy to understand that due to the arrangement of the boss 17 , when the button cover 2 is pressed, an axial pressing force is applied to the material entry channel 12 via the rotor 3 , which may cause the rotor 3 to deform inwards after long-term use.

[0081] Therefore, in this embodiment, Figure 8 As shown, a circle of upward-turned annular ribs 18 is formed on the outer edge of the boss 17. The outer edge diameter of the annular rib 18 is adapted to the inner hole diameter of the rotor 3. The inner hole of the rotor 3 is formed by the flow channel along the axial direction of the rotor 3. Figure 11 As shown, such an arrangement can prevent the rotor 3 from deforming inwards after being compressed by the annular rib 18 .

[0082] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
