Description

Technical Field

[0001] This invention relates to the field of packaging container technology for daily chemical products, and more specifically to a material dispensing device. Background Technology

[0002] In the field of daily chemical product packaging technology, pump head assemblies are often used to dispense liquid stored in containers. In traditional pump head assemblies, the button and the discharge port are integrated. In order to ensure that the button can be pressed up and down, there is usually a seam between the button and the connected container or shoulder sleeve. However, when the liquid is pressed to dispense, it is easy for the liquid to drip into the seam, which not only affects the appearance and is difficult to clean, but also contaminates the packaging.

[0003] In response to this, existing technologies have introduced a type of button-biased pump head. In this type of pump head, the discharge port and button are separate, and the discharge port remains fixed. It typically employs a button-biased design, as shown in the attached figure. Figure 1 As shown, the device includes a button 1a, a pump core 2a, and a discharge component 3a. The pump core 2a is located below the discharge component 3a, and the button 1a is located diagonally above the pump core 2a. The upper end of the discharge component 3a has an outlet 4a. The pump core 2a generally includes an upper valve, a piston, a lower valve, and a spring. The chamber between the piston and the lower valve forms the pump chamber, and the chamber between the upper valve and the outlet 4a forms the discharge chamber. In use, pressing the button 1a causes the piston to move downward, compressing the pump chamber and expanding the discharge chamber. This results in an increase in air pressure in the pump chamber and a decrease in air pressure in the discharge chamber. Under negative pressure, the upper valve opens, and the material enters the discharge chamber from the pump chamber. Releasing the button 1a causes it to reset under the action of the spring and move the piston upward. This decreases the air pressure in the pump chamber, and the lower valve opens under negative pressure, allowing the material to pass through the lower valve and enter the pump chamber. The increased air pressure in the discharge chamber, due to compression, causes the material to be extruded from the outlet 4a.

[0004] This type of pump head has the following defects: During the pumping process, due to the air pressure, the liquid will not be pumped out when the user presses button 1a, but when the user releases the button. This makes it easy for the liquid to splash when pumped out, and it does not conform to the user's pumping habits, resulting in a poor user experience. In addition, because button 1a is offset, the pump core 2a is subjected to force on one side when pressed, which leads to poor stability of pump core 2a during the pumping process, which has a significant adverse effect on the pumping effect and the life of pump core 2a. Summary of the Invention

[0005] In view of the above-mentioned deficiencies of the prior art, one embodiment of the present invention provides a material dispensing device, comprising:

[0006] A storage container, the contents of which are contained;

[0007] A pressing mechanism is located above the storage container. The pressing mechanism includes a button, a discharging component, a linkage, and a suction component. The lower part of the discharging component is slidably connected to the upper part of the linkage. The linkage is non-slidably sleeved on the outer side of the upper part of the suction component. The upper part of the suction component is provided with a first one-way check valve, which opens or closes under the action of internal air pressure. At least a portion of the linkage defines a first channel, the first end of which is sealed, and the second end of which communicates with the interior of the suction component through the first one-way check valve. The linkage has a first opening at its sidewall defining the first channel. At least a portion of the discharging component defines a second channel, the first end of which has a discharge port, and the second end of which is sealed. The discharging component has a second opening at its sidewall defining the second channel. During the movement of the linkage relative to the discharging component, the first channel communicates with the second channel through the first and second openings.

[0008] When the button moves from the first position to the second position under external pressure, it pressurizes the suction component. At least a part of the suction component moves under pressure and drives the linkage component to move. At least a part of the suction component undergoes elastic deformation, causing the internal pressure of the suction component to change accordingly. The first one-way check valve opens and discharges the contents from the discharge port through the first channel and the second channel. The position of the discharge component remains unchanged.

[0009] According to one embodiment of the present invention, the suction assembly further includes an elastic wall having a predetermined shape and thickness and a rigid base. The elastic wall is disposed below the one-way check member, and the lower end of the elastic wall is fixed in the base. When the elastic wall deforms or moves under external pressure, the position of the base remains unchanged. When the elastic wall resets, it pushes the linkage and the button to reset.

[0010] According to one embodiment of the present invention, the base is further connected directly or indirectly to the container opening of the storage container.

[0011] According to one embodiment of the present invention, the base is further provided with a third opening, and a second one-way check member is provided at the third opening. The second one-way check member opens or closes under the action of air pressure inside the suction assembly, thereby selectively sealing the third opening. The contents contained in the storage container enter the suction assembly through the second one-way check member.

[0012] According to one embodiment of the present invention, a spring element is further provided below the linkage member. The spring element assists the spring wall in pushing the linkage member and resetting the button.

[0013] According to one embodiment of the present invention, the linkage further includes a first sheath portion, the first channel being defined by at least a portion of the circumferential wall of the first sheath portion, the first opening being disposed at the circumferential wall of the first sheath portion, a pressure-bearing portion protruding in a direction away from its axis being provided on the outer side wall of the first sheath portion, and a first pressure-applying portion extending downward being provided at the lower end of the button, wherein when the button moves from the first position to the second position, the first pressure-applying portion can directly or indirectly press against the pressure-bearing portion thereby pushing the linkage and the suction assembly downward.

[0014] According to one embodiment of the present invention, the upper end of the elastic wall is provided with a second sheath extending upward along its axial direction, the first one-way check member is provided on the upper part of the second sheath and is in airtight contact with the inner wall of the second sheath, the first sheath of the linkage member is sleeved on the outside of the second sheath, a connecting part is provided between the first sheath and the second sheath, and the first sheath and the second sheath are connected through the connecting part.

[0015] According to one embodiment of the present invention, the first pressurizing portion of the button is biased to one side of the suction assembly, the pressure-bearing portion is disposed opposite to both sides of the first sheath, and the pressing mechanism further includes a transfer member. The transfer member includes a through hole and a pressure-converting portion. The through hole allows the suction assembly to pass through, and the pressure-converting portion is disposed opposite to both sides of the through hole and protrudes in a direction away from the axis of the through hole. The pressure-converting portion is disposed between the first pressurizing portion and the pressure-bearing portion, and is used to transfer pressure from the first pressurizing portion to the pressure-bearing portion. The transfer member is used to prevent the linkage and the suction assembly from being pressed on one side, ensuring the stability of the pressing mechanism and improving the user's pressing feel.

[0016] According to one embodiment of the present invention, the end of the pressure transfer section is provided with an inclined guide surface, and the lower end face of the discharge assembly is provided with a guide groove that cooperates with the guide surface. When the transfer component moves under pressure, the guide surface can slide into the guide groove. The guide groove is used to guide the movement trajectory of the transfer component and limit the horizontal displacement of the transfer component.

[0017] According to one embodiment of the present invention, the discharge port is further provided with a third one-way check valve, which opens or closes under the action of air pressure inside the second channel. The third one-way check valve can selectively seal the discharge port to prevent material near the discharge port from drying out and clogging the channel.

[0018] According to one embodiment of the present invention, a third one-way check valve is provided at the discharge port. The third one-way check valve includes a plug for sealing the discharge port and a connecting wall. The connecting wall connects the plug to the side wall of the second channel. During the movement of the button, the first sheath of the linkage abuts or moves away from the plug, causing the plug to move up to close the discharge port or fall down to open the discharge port.

[0019] The beneficial effects of this invention are:

[0020] 1. In this invention, the discharge channel composed of the first channel and the second channel can maintain a constant volume during the pressing process, overcoming the defects of the button-biased pump head in the prior art, realizing pressing to discharge and releasing to stop, which conforms to the user's pumping habits and provides a better user experience;

[0021] 2. This invention can effectively prevent material splashing during the pumping process;

[0022] 3. This invention can avoid pressure on one side of the suction component during the pressing process, ensuring uniform force and stability of the suction component (pump core), thereby improving the service life of the suction component (pump core) and the pumping effect;

[0023] 4. The present invention prevents the material at the discharge port from drying out by setting a one-way check valve at the discharge port, thus avoiding dirt or material blockage at the discharge port.

[0024] 5. The present invention has high structural reliability and is easy to industrialize.

[0025] The following will further explain the concept, specific structure, and technical effects of the present invention in conjunction with the accompanying drawings, so as to fully understand the purpose, features, and effects of the present invention. Attached Figure Description

[0044] To make the technical means, inventive features, objectives, and effects of the invention readily understandable, the invention is further illustrated below with reference to specific figures. However, the invention is not limited to the embodiments described below.

[0045] Example 1

[0046] like Figure 2 , Figure 3As shown in the figure, the present invention discloses a material distribution device, which includes a storage container 5 and a pressing mechanism 6 disposed above the storage container 5. The storage container 5 contains the contents, and the pressing mechanism 6 includes a button 1b, a suction component 2b, a discharge component 3b, a linkage component 61, a transfer component 62, and an elastic component 63.

[0047] like Figures 3-5 As shown, button 1b is located diagonally above suction assembly 2b. A first pressurizing part 11 extending downwards is provided at the lower end face of button 1b, and the first pressurizing part 11 is biased to one side of suction assembly 2b. When button 1b moves from the first position to the second position under external pressure, it pressurizes suction assembly 3b, causing at least a portion of suction assembly 3b to move under pressure and drive the linkage 61 to move. At least a portion of suction assembly 3b undergoes elastic deformation, causing its internal pressure to change accordingly, discharging the contents. During the movement of button 1b, the position of discharge assembly 3b remains unchanged.

[0048] like Figure 4 , Figure 5 As shown, the discharge assembly 3b is located on one side of the button 1b. A discharge port 31 is provided on the upper surface of the discharge assembly 3b, and a downwardly extending third sheath 32 is provided on the lower end face of the discharge assembly 3b. A downwardly extending channel wall 33a is provided on the side of the third sheath 32 away from the button 1b. A second channel 34 is defined by the channel wall 33a and a portion of the circumferential wall of the third sheath 32. The first end of the second channel 34 is connected to the discharge port 31. The lower end of the channel wall 33a bends towards the third sheath 32 and seals against it, forming a seal at the second end of the second channel 34. A second opening 321 is provided on the circumferential wall of the third sheath 32 defining the second channel 34. A third one-way check valve 311 is provided at the discharge port 31. The third one-way check valve 311 opens or closes under the action of air pressure inside the second channel 34. The third one-way check valve 311 can selectively seal the discharge port 31 to prevent material near the discharge port 31 from drying and clogging the channel.

[0049] The linkage 61 includes a first sheath 611 and a pressure-bearing part 612. The first sheath 611 extends along its axial direction, and a third sheath 32 is sleeved on the outside of the first sheath 611. The upper part of the first sheath 611 and the lower part of the third sheath 32 are slidably connected. The pressure-bearing part 612 is located on the outer wall of the first sheath 611 and protrudes in a direction away from its axis. The pressure-bearing parts 612 are arranged opposite to each other on both sides of the first sheath 611. At least a portion of the circumferential wall of the first sheath 611 defines a first channel 613. The upper part of the first sheath 611 is provided with a top cover 6112, which seals the first end of the first channel 613. The second end of the first channel 613 can communicate with the interior of the suction assembly 2b. A first opening 6111 is provided on the circumferential wall of the first sheath 611, which defines the side wall of the first channel 613. During the movement of the linkage 61 relative to the discharge assembly 3b, the first channel 613 is connected to the second channel 34 through the first opening 6111 and the second opening 321.

[0050] The suction assembly 2b includes an elastic wall 21, a base 22, and a second sheath 23. The elastic wall 21 has a predetermined shape and thickness and is capable of elastic deformation under external force. The lower end of the elastic wall 21 is fixed in the base 22, which is connected to the container opening of the storage container 5. When the elastic wall 21 deforms or moves under external pressure, the position of the base 21 remains unchanged. The upper end of the elastic wall 21 is provided with a second sheath 23 extending upward along its axial direction. The first sheath 611 of the linkage 61 is non-sliply sleeved on the outside of the second sheath 23. A connecting part is provided between the first sheath 611 and the second sheath 23, and the first sheath 611 and the second sheath 23 are connected through the connecting part.

[0051] The upper part of the second sheath 23 is provided with a first one-way check valve 24 that is airtightly connected to its inner wall. The first one-way check valve 24 can be a silicone valve, ball valve, or umbrella valve, etc. The first one-way check valve 24 is opened or closed under the action of the air pressure inside the suction assembly 2b. When the first one-way check valve 24 is open, the second end of the first channel 613 is connected to the inside of the suction assembly 2b.

[0052] The base 22 is provided with a third opening 221, and the third opening 221 is provided with a second one-way check member 222. The second one-way check member 222 opens or closes under the action of air pressure inside the suction assembly 2b, thereby selectively sealing the third opening 221. The contents contained in the storage container 5 enter the suction assembly 2b through the second one-way check member 222.

[0053] Below the linkage 61 is an elastic element 63, which is used to assist the elastic wall 21 in pushing the linkage 61 and the button 1b to reset.

[0054] like Figure 6 As shown, the transfer component 62 includes a through hole 621 and a pressure transfer part 622. The through hole 621 allows the second sheath 23 of the suction assembly 2b to pass through. The pressure transfer part 622 is disposed on both sides of the through hole 621 and protrudes in a direction away from the axis of the through hole 621. The pressure transfer part 622 is located between the first pressurizing part 11 and the pressure bearing part 612, and is used to transfer pressure from the first pressurizing part 11 to the pressure bearing part 612. The end of the pressure transfer part 622 is provided with an inclined guide surface 6221, and the lower end face of the discharge assembly 3b is provided with a guide groove 35 that cooperates with the guide surface 6221. When the transfer component moves under pressure, the guide surface can slide into the guide groove 35. The guide groove 35 is used to guide the movement trajectory of the transfer component 62 and limit the horizontal displacement of the transfer component 62.

[0055] When button 1b moves from the first position to the second position, the first pressurizing part 11 presses down against the pressure-reducing part 622, and the pressure-reducing part 622 then presses down against the pressure-bearing part 612, thereby pushing the linkage 61 and the suction assembly 2b downward. Since the pressure-reducing part 622 and the pressure-bearing part 612 are provided on both sides, when the pressure-bearing part 612 pushes down the suction assembly 2b, the suction assembly 2b is subjected to force evenly on both sides.

[0056] The technical solution described in the above embodiments is used as follows:

[0057] like Figure 5 As shown, when button 1b is pressed, the first pressing part 11 located at the lower end face of button 1b presses down against the pressing part 622. After the pressing part 622 bears the force, it presses down against the pressure-bearing part 612 at the linkage 61. When the linkage 61 moves downward, it drives the second sheath 23 of the suction assembly 2b. Since the position of the base 22 of the suction assembly 2b remains unchanged, when the second sheath 23 moves downward, the elastic wall 21 of the suction assembly 2b undergoes elastic deformation, the space inside the suction assembly 2b is compressed, the air pressure increases, and the first one-way check piece 24 opens under the action of air pressure.

[0058] like Figure 4 As shown, when button 1b is released, the elastic wall 21 resets and, under the action of the elastic element 63, pushes the linkage 61, the transfer element 62, and button 1b to reset. The space inside the suction assembly 2b expands, the air pressure decreases, and the second one-way check valve 222 opens under the action of air pressure, allowing the contents contained in the storage assembly 5 to enter the interior of the suction assembly 2b. Pressing button 1b again, under the action of air pressure, the first one-way check valve 24 opens, and the contents enter the first channel 613, and enter the second channel 34 through the first opening 6111 on the side wall of the first channel 613 and the second opening 321 on the side wall of the second channel 34. The discharge channel formed by the first channel 613 and the second channel 34 is compressed due to the contents being filled, and the air pressure increases. The third one-way check valve 311 opens under pressure, allowing the contents to be pumped out from the discharge port 31.

[0059] During the movement of button 1b, there is no relative movement between the linkage 61 and the suction component 2b. Therefore, the volume of the first channel 613 remains unchanged. At the same time, since the position of the discharge component 3b is fixed, the volume of the second channel 34 remains unchanged. That is, during the movement of button 1b, the volume of the discharge channel composed of the first channel 613 and the second channel 34 is constant, which enables the present invention to pump out the material when pressed and stop discharging when released.

[0060] Example 2:

[0061] like Figure 7 , Figure 8 As shown, the discharge assembly 3b does not have a channel wall 33a. The discharge assembly 3b includes a channel member 33b, a third sheath 32 sleeved outside the channel member 33b, and the channel member 33b covering the first sheath 611. The lower end of the channel member 33b is sealed to the lower end of the third sheath 32, and the gap between the third sheath 32 and the channel member 33b forms a second channel 34. A plug 3111 is provided at the end of the channel member 33b near the discharge port 31. The plug 3111 is used to seal the discharge port 31, and the plug is connected to the main body of the channel member 33b through a flexible connecting wall 3112.

[0062] When button 1b is in the first position, the lower end of plug 3111 abuts against the top cover 6112 of linkage 61, and the upper end of plug 3111 abuts against discharge port 31 to seal discharge port 31.

[0063] Press button 1b to move it from the first position to the second position. Link 61 moves downward relative to discharge assembly 3b. The lower end of plug 3111 no longer abuts against top cover 6112. Due to the elasticity of connecting wall 3112, plug 3111 moves downward under its own weight to open discharge port 31.

[0064] Release button 1b to return it from the second position to the first position, the linkage 61 resets, and the top cover 6112 pushes the plug 3111 to reset, thereby closing the discharge port 31.

[0065] The remaining structure and usage are the same as in Example 1.
