Description

Technical Field

[0001] This utility model relates to the field of fluid distribution technology, and in particular to a dual-channel fluid product distributor. Background Technology

[0002] In existing technologies, fluid dispensers use a configured press pump to pump fluid from a container to a nozzle, through which the user obtains the desired fluid. There are also designs that install nozzles at the nozzles, allowing the fluid to be ejected in a specific form, such as a mist or foam.

[0003] However, when a fluid product dispenser is required to provide two different forms of fluid products simultaneously, the existing technology involves equipping the container with two press pumps, each corresponding to a nozzle, and installing corresponding nozzles at the two nozzles. Thus, when in use, the corresponding press pump is operated as needed to obtain two different forms of fluid products.

[0004] However, because the container needs to be equipped with two or more press pumps, its structure is more complex, resulting in higher manufacturing costs and a greater likelihood of failure. Furthermore, the increased complexity also reduces the container's storage space within a fixed size, leading to a decrease in the capacity for storing fluid products.

[0005] For example, the multifunctional container packaging bottle disclosed in Chinese utility model patent CN217893566U, although a single container packaging bottle, is actually composed of two independently operating containers combined. Besides the aforementioned problems, this also presents the issue of asynchronous consumption of the fluid products stored in the two liquid storage chambers. Utility Model Content

[0006] In view of the problem that existing fluid product dispensers use two sets of press pumps and nozzles to supply two types of fluid products, resulting in complex structure and high cost, the purpose of this utility model is to provide a dual-channel fluid product dispenser to at least partially solve the above problems.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows:

[0008] A dual-channel fluid product dispenser includes a fluid product container and a dual-spray button. A press pump is fixed to the fluid product container. The dual-spray button includes a button body, a button cover, and a rotor disposed between the button body and the button cover. The button body is axially slidably connected relative to the fluid product container, and an anti-rotation structure is provided between the button body and the fluid product container. The button body also has a fluid inlet channel adapted to the discharge end of the press pump, and two fluid spray channels, one of which is equipped with a nozzle that sprays the fluid product in a mist form. The nozzle is provided; the button cover is circumferentially rotatable relative to the button body; the rotor is provided with a flow channel, and the rotor can rotate relative to the button body under the drive of the button cover; the button cover is provided with a stop structure, and the button body is provided with a corresponding limiting structure. The limiting structure is formed on the fluid ejection channel and blocks the rotation path of the stop structure. The stop structure and / or the limiting structure are provided in two places so that the rotor can stop at two positions where the fluid enters the channel and is connected to the two fluid ejection channels respectively through the flow channel.

[0009] In some preferred embodiments, the fluid inlet channel is formed by constructing a fluid inlet pipe, the fluid outlet channel is formed by constructing a fluid outlet pipe, and both fluid outlet pipes are connected to the fluid inlet pipe.

[0010] In some preferred embodiments, the rotor is sealed within the fluid inlet pipe, the first end of the flow channel is connected to the fluid inlet pipe, and the second end is formed with a side hole on the circumferential wall of the rotor. The fluid inflow ports of the two fluid ejection pipes are both located on the rotation path of the side hole.

[0011] In some preferred embodiments, the inner wall of the fluid inlet pipe is formed with a step for supporting the rotor, and an annular support is formed on the step, the annular support being adapted to the first end port of the flow channel.

[0012] In some preferred embodiments, the fluid product container includes a container body with a neck and a pressure cap detachably fixed to the neck. The pressure cap also has a through hole for the discharge end of the press pump to pass through. The press pump is axially fixed to the pressure cap or the neck, and the button body is axially slidably connected to the pressure cap.

[0013] In some preferred embodiments, the button body and the pressure cover are inserted into each other with a clearance fit; when the mating cross section of the button body and the pressure cover is circular, the anti-rotation structure includes an axial retaining rib provided on one of the button body and the pressure cover and an axial retaining groove provided on the other; when the mating cross section of the button body and the pressure cover is non-circular, the button body and the pressure cover achieve anti-rotation through the non-circular mating cross section.

[0014] In some preferred embodiments, the rotor has a rib groove on one end face facing the button cover, and the button cover has corresponding ribs.

[0015] In some preferred embodiments, the stop structure and the limiting structure are in point contact, line contact, or surface contact.

[0016] In some preferred embodiments, the inner side of the top wall of the button cover is provided with an annular wall structure, and the stop structure is connected to both the inner side of the top wall of the button cover and the outer side of the annular wall structure.

[0017] In some preferred embodiments, when there are two stop structures, the outer edges of the two stop structures are connected by reinforcing ribs.

[0018] The beneficial effects of this utility model by adopting the above technical solution are as follows: By setting a stop structure on the button cover and a limiting structure on the button body, with the limiting structure blocking the rotation path of the stop structure, the rotor can be stopped at a position where the press pump is connected to the two fluid ejection channels when the button cover is rotated. Furthermore, by setting a nozzle in one of the fluid ejection channels, the two fluid product nozzles can eject different forms of fluid products, thus adapting to different usage environments. Compared to existing technologies, this utility model only requires one press pump to supply two different forms of fluid products, thereby simplifying the product structure and reducing manufacturing costs, and also helping to ensure fluid product storage capacity.

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

[0040] Example 1

[0041] A dual-channel fluid product dispenser, such as Figure 1-5 As shown, it includes a fluid product container and a dual-jet button.

[0042] The fluid product container includes a container body 1, which is generally cylindrical in shape and has a neck at the top. A press pump 3 is arranged in the neck, which can pump out the fluid product stored in the fluid product container.

[0043] The fluid product container also includes a gland 2, which is fixedly connected to the neck of the container body 1. For example, an external thread is provided on the outer wall of the neck, and an internal thread is provided on the lower inner wall of the gland 2, so that the gland 2 and the neck of the container body 1 are detachably fixedly connected by threads. In addition, the gland 2 has a through hole for the discharge end of the press pump 3 to pass through, and the housing of the press pump 3 has a flange to allow the press pump 3 to be pressed between the gland 2 and the top of the neck of the fluid product container. This arrangement allows the press pump 3, the gland 2, and the container body 1 to be easily separated. Alternatively, the housing of the press pump 3 can be fixed in the neck of the container body 1 by welding, integral injection molding, or threaded connection; of course, the housing of the press pump 3 can also be fixed to the gland 2 by welding, integral injection molding, or threaded connection.

[0044] It is easy to understand that the cap 2 can also be part of the container body 1, for example, the cap 2 is the part that extends from the neck of the container body 1.

[0045] like Figure 6-14 As shown, the dual-jet button includes a button body 4, a button cover 5, and a rotor 6 disposed between the button body 4 and the button cover 5.

[0046] The button body 4 is axially slidably connected to the pressure cover 2. For example, both the lower part of the button body 4 and the upper part of the pressure cover 2 are formed into a cylindrical structure, and they are interlocked with a clearance fit. There are several ways in which the button body 4 and the pressure cover 2 are interlocked. For example, both the lower cylindrical structure of the button body 4 and the upper cylindrical structure of the pressure cover 2 are single-layer structures, and the button body 4 can be on the outside or on the inside; or the lower cylindrical structure of the button body 4 can be a single-layer structure, and the upper cylindrical structure of the pressure cover 2 can be a double-layer structure, with the lower cylindrical structure of the button body 4 inserted into the double-layer cylindrical structure of the pressure cover 2; or the lower cylindrical structure of the button body 4 can be a double-layer structure, and the upper cylindrical structure of the pressure cover 2 can be a single-layer structure, with the upper cylindrical structure of the pressure cover 2 inserted into the double-layer cylindrical structure of the button body 4.

[0047] In addition, an anti-rotation structure is provided between the button body 4 and the pressure cover 2. When the cross-section of the button body 4 and the pressure cover 2 that mates with each other is circular, the anti-rotation structure is configured to include an axial retaining rib 41 provided on the button body 4, such as... Figure 8 As shown, and the corresponding axial groove 21 opened on the pressure cap 2, as Figure 9-11As shown, the axial groove 21 forms a filling port at the top of the cover 2 for the axial retaining rib 41 to enter and exit; of course, the axial retaining rib can also be set on the cover 2, and the axial groove can be set on the button body 4. It is easy to understand that regardless of whether the cylindrical structure at the bottom of the button body 4 and the cylindrical structure at the top of the cover 2 are single-layer or double-layer structures, the axial groove is usually configured to be hidden. For example, when the cylindrical structure at the bottom of the button body 4 is a single-layer structure and the cylindrical structure at the top of the cover 2 is a double-layer structure, the axial retaining rib 41 is set on one side of the inner wall of the cylindrical structure at the bottom of the button body 4, and the axial groove 21 is set on the inner layer of the cylindrical structure at the top of the cover 2, so that both the axial groove and the axial retaining rib are invisible when in use.

[0048] In other preferred embodiments, the mating cross section of the button body 4 and the pressure cover 2 can be non-circular, such as triangular, rectangular, polygonal, elliptical, etc., so that the button body 4 and the pressure cover 2 can achieve anti-rotation design through the non-circular mating cross section.

[0049] The button body 4 is provided with a fluid inlet channel 42 adapted to the discharge end of the press pump 3, such as... Figure 8 As shown, the fluid inlet channel 42 is formed by a fluid inlet pipe structure. The fluid inlet pipe and the button body 4 are integrally formed. The lower end of the fluid inlet pipe and the discharge end of the press pump 3 are mutually inserted and matched, for example, with an interference fit, so that the button body 4 will not easily separate from the pressure cover 3.

[0050] like Figure 6-8 As shown, the button body 4 also has two fluid ejection channels 43, both of which are formed by fluid ejection pipes. Both fluid ejection pipes are connected between the fluid inlet pipe and the button body 4; for example, the fluid ejection pipes are integrally formed between the button body 4 and the fluid inlet pipe. One end of each of the two fluid ejection pipes (called the inner port or fluid inflow port) is connected to the aforementioned fluid inlet pipe, and the other end of each of the two fluid ejection pipes (called the outer port or fluid outflow port) penetrates the side wall of the button body 4.

[0051] In this embodiment, a nozzle 7 is installed in one of the fluid ejection channels 43 to eject the fluid product in a mist form, such as... Figure 4 As shown, another fluid ejection channel 43 does not have an additional nozzle installed, thus enabling the fluid product to be ejected in both fluid and mist forms.

[0052] The button cover 5 is located on top of the button body 4. The button cover 5 is rotatably connected to the button body 4. An clearance opening 51 is also provided on the side wall of the button cover. Figure 12As shown, the clearance opening 51 can be either a through hole or a notch. When the button cover 5 is rotated circumferentially relative to the button body 4, the clearance opening 51 can be made to face the outer ports of the two fluid ejection channels 43 respectively.

[0053] like Figure 13-14 As shown, the rotor 6 is sealed at the top of the fluid inlet channel 42. The rotor 6 can rotate relative to the button body 4 under the action of the button cover 5. For example, a rib groove 61 is provided on the top of the rotor 6 (i.e., the end face facing the button cover 5), and a corresponding rib 52 is provided on the button cover 5, so that the rotor 6 can rotate relative to the button body 4 under the action of the button cover 5. Of course, the rib groove can also be provided on the button cover 5, and the rib can be provided on the rotor 6.

[0054] The rotor 6 is provided with a flow channel. The first end of the flow channel is connected to the fluid inlet channel 42. The second end of the flow channel is formed into a side hole 62 on the circumferential wall of the rotor 6. The fluid inlet ports of the two fluid ejection pipes are located on the rotation path of the side hole 62. In this way, when the rotor 6 rotates, the fluid inlet channel 42 can be connected to the two fluid ejection channels 43 respectively.

[0055] In this embodiment, the button cover 5 and the button body 4 are detachably connected by a snap-fit ​​structure, preventing the button cover 5 and the button body 4 from easily separating axially. Specifically, as shown... Figure 12 As shown, an annular wall structure 53 is formed on the top wall of the button cover 5. The top of the fluid inlet channel 42 (together with the rotor 6) extends into the annular wall structure 53, and the fluid inlet pipe constituting the fluid inlet channel 42 is connected to the annular wall structure 53 by a snap-fit ​​structure.

[0056] The button cover 5 is also provided with a stop structure 8, and the button body 4 is provided with a corresponding limit structure 9, which blocks the rotation path of the stop structure 8.

[0057] In this embodiment, as Figure 12 As shown, there are two stop structures 8 and two limit structures 9. The circumferential angle between the two limit structures 9 is approximately equal to the circumferential angle between the two fluid ejection channels 43. The circumferential angle between the two stop structures 8 is approximately twice the circumferential angle between the two fluid ejection channels 43.

[0058] The limiting structure 9 can be formed on the fluid ejection channel 43, such as Figure 7 As shown, the limiting structure 9 can also be the fluid ejection channel 43 itself or formed on the inner circumference of the button body 4. The stop structure 8 can be formed on the outer wall of the annular wall structure 53, or it can be formed on the top wall of the button cover 5, or the stop structure 8 can be formed on both the outer wall of the annular wall structure 53 and the inner bottom wall of the button cover 5.

[0059] It is easy to understand that the outer edges of the two stop structures 8 are also connected by reinforcing ribs 10, such as Figure 12 As shown, the reinforcing rib 10 is arc-shaped and is located on the outer side of the annular wall structure 53, while also connecting the reinforcing rib 10 to the top wall of the button cover 5. This arrangement further enhances the structural strength of the two stop structures 8.

[0060] In this embodiment, the stop structure 8 is preferably a flat plate, with its surface parallel to the rotation axis of the button cover 5. Correspondingly, a planar contact surface is also provided on the outer wall of the fluid ejection channel 43, so that the stop structure 8 can form a more stable contact with the fluid ejection channel 43. Of course, in other preferred embodiments, the stop structure 8 can also be other shapes, and the contact between the stop structure 8 and the fluid ejection channel 43 can also be point contact, line contact, or curved surface contact.

[0061] Specifically, the positions of the stop structure 8 and the limiting structure 9 satisfy the following: Figure 3 As shown, during the process of the button cover 5 driving the rotor 6 to rotate (viewed from above, the button cover 5 is in a counterclockwise direction), when one of the stop structures 8 (hereinafter referred to as stop structure A for ease of understanding) hits the limiting structure 9 formed on one of the fluid ejection channels 43 (hereinafter referred to as channel A for ease of understanding), the side hole 62 of the rotor 6 is just aligned with the other fluid ejection channel 43 (hereinafter referred to as channel B for ease of understanding). At this time, the button cover 5 cannot continue to rotate in the counterclockwise direction, but can only rotate in the clockwise direction. During the process of the button cover 5 driving the rotor 6 to rotate in the clockwise direction, when the other stop structure 8 (hereinafter referred to as stop structure B for ease of understanding) hits the limiting structure 9 formed on the other fluid ejection channel 43 (i.e., channel B), the side hole 62 of the rotor 6 is just aligned with one of the fluid ejection channels 43 (i.e., channel A).

[0062] Example 2

[0063] It is easy to understand that, in order to achieve the above-mentioned stopping effect, the number and position of the stopping structure 8 and the limiting structure 9 are not limited to the above scheme. There are also the following alternative schemes: only one stopping structure 8 is configured, while two limiting structures 9 are configured. The circumferential angle between the two limiting structures 9 is still approximately the same as the circumferential angle between the two fluid ejection channels 43. The installation method of the stopping structure 8 and the limiting structure 9 is the same as that of Embodiment 1 above.

[0064] The positions of the stop structure 8 and the limit structure 9 are configured to satisfy the following: Figure 15As shown, during the process of the button cover 5 driving the rotor 6 to rotate (viewed from above, the button cover 5 is in a clockwise direction), when the stop structure 8 hits the limiting structure 9 formed on one of the fluid ejection channels 43 (hereinafter referred to as channel A for ease of understanding), the side hole 62 of the rotor 6 is just aligned with the fluid ejection channel 43 (i.e., channel A). At this time, the button cover 5 cannot continue to rotate in the clockwise direction, but can only rotate in the counterclockwise direction. During the process of the button cover 5 driving the rotor 6 to rotate in the counterclockwise direction, when the stop structure 8 hits the limiting structure 9 formed on another fluid ejection channel 43 (i.e., channel B), the side hole 62 of the rotor 6 is just aligned with the fluid ejection channel 43 (i.e., channel B).

[0065] Example 3

[0066] It is easy to understand that, in order to achieve the above-mentioned stopping effect, the number and position of the stopping structure 8 and the limiting structure 9 can also be replaced by the following alternatives: two stopping structures 8 are configured, and one limiting structure 9 is configured. The circumferential angle between the two stopping structures 8 is still equivalent to the circumferential angle between the two fluid ejection channels 43. The installation method of the stopping structure 8 and the limiting structure 9 is the same as that of Embodiment 1 above.

[0067] The positions of the stop structure 8 and the limit structure 9 are configured to satisfy the following: Figure 16 As shown, during the process of the button cover 5 driving the rotor 6 to rotate (viewed from above, the button cover 5 is in a clockwise direction), when one of the stop structures 8 (hereinafter referred to as stop structure A for ease of understanding) hits the limiting structure 9 formed on the fluid ejection channel 43 (hereinafter referred to as channel A for ease of understanding), the side hole 62 of the rotor 6 is just aligned with the fluid ejection channel 43 (i.e., channel A). At this time, the button cover 5 cannot continue to rotate in the clockwise direction, but can only rotate in the counterclockwise direction. During the process of the button cover 5 driving the rotor 6 to rotate in the clockwise direction, when another stop structure 8 (hereinafter referred to as stop structure B for ease of understanding) hits the limiting structure 9 formed on the fluid ejection channel 43 (i.e., channel A), the side hole 62 of the rotor 6 is just aligned with the other fluid ejection channel 43.

[0068] Example 4

[0069] In this embodiment, as Figure 8 As shown, the inner wall of the fluid inlet channel 42 is provided with a step 44 for supporting the bottom of the rotor 6. With this configuration, when the button cover 5 is pressed, the bottom of the rotor 6 will press against the top surface of the step 44, thereby preventing the side hole 62 of the rotor 6 from axially displacing relative to the fluid inlet channel 42, and avoiding the side hole 62 of the rotor 6 from being misaligned with the fluid ejection channel 43 in the axial direction.

[0070] It is easy to understand that, due to the setting of step 44, when the button cover 5 is pressed, the axial pressing force will be applied to the fluid inlet channel 42 by the rotor 6, which may cause the rotor 6 to deform inward after long-term use.

[0071] Therefore, in this embodiment, as Figure 8 As shown, an upward-turning annular support 45 is formed on the outer edge of the step 44. The outer diameter of the annular support 45 is matched with the inner diameter of the rotor 6. The inner diameter of the rotor 6 is formed by the flow channel in the rotor 6 along the axial direction. With this arrangement, the annular support 45 can prevent the rotor 6 from deforming inward under pressure.

[0072] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
