Description

Technical Field

[0001] This application relates to the field of daily chemical products technology, and in particular to a press pump and container. Background Technology

[0002] Currently, the main personal hygiene products on the market are no-rinse antibacterial / disinfecting hand sanitizers, gels, and rubbing alcohol, as well as water-based antibacterial / disinfecting lotions and foams. These water-based products are primarily packaged in a standard pump-and-bottle format, and these pump-type products have at least one of the following problems:

[0003] 1. In water washing scenarios, various products are placed in a crowded manner, and the operating space is small, which makes operation inconvenient. Without sufficient operating space and height, it is difficult to reach in with both hands, which does not conform to the actual operating habits of users and is inconvenient to operate.

[0004] 2. Currently, pump products generally have excessively high operating pressures, especially for high-volume, high-viscosity liquid formulations, which is not very suitable for certain groups of people.

[0005] 3. Currently, the user behavior of pump products deviates somewhat from the original design intent of the interactive experience. They are not suitable for one-handed operation, and one-handed operation can easily lead to liquid spillage, resulting in a poor user experience.

[0006] 4. After prolonged use, pump products may experience blockages or shrinkage in the outlet nozzle due to poor liquid cut-off or solidification, affecting normal liquid output. Summary of the Invention

[0057] The following is in conjunction with the appendix Figure 1-1 To be continued Figure 4-3 The embodiments of this application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0058] In the description of this application, it should be understood that the use of terms such as "center," "middle," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" to indicate orientation or positional relationships is based on the orientation or positional relationships shown in the accompanying drawings and is only for the convenience of describing this application and simplifying the description. It does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Features defined with "first" and "second" are used to distinguish feature names and do not have special meanings. Furthermore, features defined with "first" and "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "multiple" means two or more.

[0059] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0060] This application relates to a container equipped with a pressure pump located at the container opening. Applying pressure to the pressure pump allows liquid to be dispensed.

[0061] Understandably, the container is set as a bottle or can.

[0062] In some examples, the container opening is located at the top of the container, so applying downward pressure to the pump dispenses liquid. In some alternative examples, the container opening is located at the bottom of the container, so applying upward pressure dispenses liquid.

[0063] Other components and operations of the container are already described in the relevant art to those skilled in the art, and will not be described in detail here. The structure of the press pump will be described below.

[0064] This application relates to a press pump, which includes a cover 1000, a pump body 2000, and a pressing assembly. The cover 1000 is disposed at the container opening and is threadedly connected to the side wall of the container opening. The pump body 2000 is connected to the cover 1000, and the pressing assembly is disposed on the cover 1000. It is understood that when a user applies pressure to the pressing assembly, the pressing assembly presses the pump body 2000, and the pump body 2000 pumps liquid from the container, thus dispensing the liquid.

[0065] It should be noted that the structure of the pump body 2000 has been described in relevant technologies and will not be repeated here.

[0066] Referring to the accompanying drawings, the pressing assembly includes a press head 3100 and a pressing rod 3200. The press head 3100 is hinged to the cover 1000, and the pressing rod 3200 is disposed on the cover 1000 and is movable on the cover 1000. The first end of the pressing rod 3200 abuts against the press head 3100, and the second end of the pressing rod 3200 is connected to the pump body 2000. Specifically, the press head 3100 is pressed and applies pressure to the first end of the pressing rod 3200 in the form of a lever, causing the pressing rod 3200 to press down on the pump body 2000, thereby causing the pump body 2000 to dispense liquid. Further, the pressing rod 3200 is hollow, forming a liquid outlet channel, and the liquid outlet channel of the pressing rod 3200 is connected to the liquid outlet channel of the pump body 2000.

[0067] It is understood that the pressing assembly includes a liquid outlet area 3300 and a liquid outlet pipe 3400. The liquid outlet area 3300 is disposed on the press head 3100. Specifically, the liquid outlet area 3300 is disposed on the inner side wall of the press head 3100. The two ends of the liquid outlet pipe 3400 are respectively connected to the pressing rod 3200 and the liquid outlet area 3300, and the liquid outlet pipe 3400 connects to the liquid outlet channel of the pressing rod 3200, so that a complete and continuous liquid outlet channel is formed from the pump body 2000 to the liquid outlet area 3300. Furthermore, the liquid outlet pipe 3400 is configured as a flexible hose, and the liquid outlet pipe 3400 is flexible to accommodate the deformation caused by the press head 3100 under pressure.

[0068] A pressing area 3110 is provided on the side wall of the pusher head 3100 facing away from the cover 1000. Specifically, the pressing area 3110 is located on the upper side of the pusher head 3100. When the user applies pressure to the pressing area 3110, the pusher head 3100 rotates towards the cover 1000. The pusher head 3100 is pressed and applies pressure to the pressing rod 3200 in the form of a lever. The pressing rod 3200 applies pressure to the pump body 2000, and the pump body 2000 pumps liquid and discharges liquid in the form of bubbles or fluid.

[0069] Referring to the accompanying drawings, one end of the press head 3100 is hinged to the cover 1000, the pressing area 3110 is located on the side of the other end of the press head 3100, and the first end of the pressing rod 3200 abuts against the middle of the side of the press head 3100 facing the cover 1000. Furthermore, between the pressing area 3110 and the hinge position between the press head 3100 and the cover 1000, the connection position between the pressing rod 3200 and the press head 3100 is closer to the hinge position between the press head 3100 and the cover 1000, thereby increasing the distance between the pressing area 3110 and the connection position between the pressing rod 3200 and the press head 3100, making it easier to dispense liquid.

[0070] In one embodiment, the push head 3100 and the pressing rod 3200 are connected by a first hinge structure. The first hinge structure includes a first hinge shaft 4101 and a recessed first hinge area 4102, with the end of the first hinge shaft 4101 disposed in the first hinge area 4102. Specifically, one of the first hinge shaft 4101 and the first hinge area 4102 is disposed on the side wall of the push head 3100, and the other is disposed on the side wall of the pressing rod 3200.

[0071] Further, one of the first hinge shaft 4101 and the first hinge area 4102 is disposed on the inner sidewall of the press head 3100, and the other is disposed on the outer sidewall of the pressing rod 3200. In some examples, the first hinge shaft 4101 is disposed on the outer sidewall of the pressing rod 3200, and the first hinge area 4102 is disposed on the inner sidewall of the press head 3100. Specifically, the first hinge area 4102 is disposed at two opposite inner sidewalls on the press head 3100, and the first hinge shaft 4101 is disposed at two symmetrical positions on the outer sidewall of the pressing rod 3200. The two first hinge shafts 4101 are respectively hinged to the two first hinge areas 4102. When the press head 3100 is rotated under force, the press head 3100 and the pressing rod 3200 rotate relative to each other.

[0072] In some alternative examples, the first hinge axis 4101 is disposed on the inner sidewall of the push head 3100, and the first hinge area 4102 is disposed on the outer sidewall of the push rod 3200.

[0073] In some embodiments, the cross-sectional area of ​​the first hinge shaft 4101 is smaller than the area of ​​the first hinge region 4102, so that when the push head 3100 applies pressure to the pressing rod 3200, the first hinge shaft 4101 slides in the first hinge region 4102. In this case, relative sliding can occur between the first hinge shaft 4101 and the first hinge region 4102 when the push head 3100 applies pressure to the pressing rod 3200 or when the pressing rod 3200 rebounds and pushes the push head 3100.

[0074] Specifically, when the press head 3100 applies pressure to the pressing rod 3200, the pressing rod 3200 moves along an axis parallel to the centerline of the cover 1000 and presses the pump body 2000. After the user releases the press head 3100, the pump body 2000 applies a force in the opposite direction to the pressing rod 3200, causing the pressing rod 3200 to move along an axis parallel to the centerline of the cover 1000 and rebound to lift the press head 3100. Therefore, the design of relative sliding between the first hinge shaft 4101 and the first hinge area 4102 can compensate for positional changes between the pressing rod 3200 and the press head 3100, thereby preventing the linear movement of the pressing rod 3200 from interfering with the rotation of the press head 3100 and ensuring smooth operation of the pressing assembly.

[0075] On the other hand, by abutting and limiting the outer wall of the first hinge shaft 4101 through the inner sidewall of the first hinge area 4102, the first hinge shaft 4101 can be prevented from separating from the first hinge area 4102, that is, the first hinge shaft 4101 and the first hinge area 4102 can be prevented from separating, thereby preventing the press head 3100 from the press rod 3200 when the press rod 3200 rebounds, and ensuring the structural integrity of the pressing assembly.

[0076] In some examples, the first hinge axis 4101 is configured as a cylindrical boss, and the first hinge area 4102 is configured as a groove. It is understood that, in order to compensate for positional changes between the pressing rod 3200 and the pressing head 3100, the first hinge axis 4101 can reciprocate along the groove.

[0077] In some embodiments, when the first hinge area 4102 is located on the side wall of the push head 3100, the side wall of the first hinge area 4102 protrudes from the side wall of the push head 3100, and a first guide slope is provided on the outer side of the side wall of the first hinge area 4102 so that the end of the first hinge shaft 4101 can be engaged into the first hinge area 4102 along the first guide slope.

[0078] It is understood that in some alternative embodiments, if the first hinge area 4102 is located on the side wall of the push head 3100, it is designed such that the side wall of the first hinge area 4102 protrudes from the side wall of the push rod 3200.

[0079] In one embodiment, the upper surface of the cover 1000 is provided with a hollow cylindrical mounting area 1100. The second end of the pressing rod 3200 passes through the mounting area 1100 and is connected to the pump body 2000. When the pressing head 3100 applies pressure to the pressing rod 3200, the pressing rod 3200 can move axially along the mounting area 1100.

[0080] Furthermore, a first guide structure is provided between the pressing rod 3200 and the mounting area 1100. When the pressing rod 3200 moves along the axial direction of the mounting area 1100, the first guide structure is used to limit the movement direction of the pressing rod 3200 and prevent relative rotation between the pressing rod 3200 and the mounting area 1100.

[0081] Specifically, the first guide structure includes a first guide groove 4201 and a first guide protrusion 4202. The first guide groove 4201 is arranged in a vertical direction parallel to the axial direction of the pressing rod 3200. The first guide protrusion 4202 is slidably disposed in the first guide groove 4201. When the pressing head 3100 applies pressure to the pressing rod 3200, the first guide protrusion 4202 slides relative to the pressing rod 3200 in the first guide groove 4201 in a vertical direction. When the outer side wall of the pressing rod 3200 is set as a cylindrical side wall and the mounting area 1100 is set as a cylindrical structure, the restriction of the first guide protrusion 4202 by the inner side wall of the first guide groove 4201 can prevent the pressing rod 3200 from rotating in the mounting area 1100.

[0082] It is understood that one of the first guide groove 4201 and the first guide protrusion 4202 is disposed on the side wall of the pressing rod 3200, and the other is disposed on the side wall of the mounting area 1100. In some examples, the first guide groove 4201 is disposed on the side wall of the pressing rod 3200, and the first guide protrusion 4202 is disposed on the side wall of the mounting area 1100. In some alternative examples, the first guide groove 4201 is disposed on the side wall of the mounting area 1100, and the first guide protrusion 4202 is disposed on the side wall of the pressing rod 3200.

[0083] In some embodiments, referring to the accompanying drawings, an annular first baffle 3210 is provided on the outer side of the pressing rod 3200. An annular region is formed between the inner sidewall of the first baffle 3210 and the outer sidewall of the pressing rod 3200. The pressing rod 3200 is inserted into the hollow region of the mounting area 1100, and the sidewall of the mounting area 1100 is inserted into the annular region. A first guide groove 4201 is provided on the first baffle 3210, and a first guide protrusion 4202 is provided on the outer sidewall of the mounting area 1100. In this case, the first guide groove 4201 extends to the end of the first baffle 3210 facing the cover 1000 and forms a notch, allowing the first guide protrusion 4202 to enter the first guide groove 4201.

[0084] In some alternative embodiments, the first guide protrusion 4202 may be disposed on the first baffle 3210, the first guide groove 4201 may be disposed on the side wall of the mounting area 1100, and the first guide groove 4201 may extend to the end of the mounting area 1100 and form a notch, so that the first guide protrusion 4202 may enter the first guide groove 4201.

[0085] Regarding the implementation scheme for restricting relative rotation between the pressing rod 3200 and the mounting area 1100, it can also be designed as follows: the mounting area 1100 is set as a polygonal cylindrical cavity, and the corner structure of the side wall of the mounting area 1100 serves as the first guide structure.

[0086] In one embodiment, the press pump includes a limit buckle 5000, which is detachably disposed on the upper surface of the cover 1000. Specifically, the limit buckle 5000 is engaged between the press rod 3200 and the cover 1000, and the limit buckle 5000 is used to prevent the press rod 3200 from pressing the pump body 2000.

[0087] Understandably, when the limiting buckle 5000 is located between the pressing rod 3200 and the cover 1000, one end of the limiting buckle 5000 abuts against the cover 1000, and the other end abuts against the first baffle 3210 on the outside of the pressing rod 3200, thus fixing the position of the pressing rod 3200. Even if the user applies pressure to the push head 3100, the pressing rod 3200 cannot press the pump body 2000 due to the pressure of the push head 3100, thereby preventing accidental liquid discharge from the container when not in use for a long time. Accordingly, removing the limiting buckle 5000 from the pump releases the restriction of the limiting buckle 5000 on the pressing rod 3200 and the pump body 2000.

[0088] In some examples, the limit buckle 5000 is engaged with the outer wall of the mounting area 1100. Specifically, the limit buckle 5000 has a circumferential sidewall, and the circumferential sidewall of the limit buckle 5000 is provided with a notch to form a snap-fit ​​opening for the limit buckle 5000. The cross-section of the limit buckle 5000 is "C" shaped. When the limit buckle 5000 is engaged with the mounting area 1100, the outer wall of the mounting area 1100 is engaged through the notch of the limit buckle 5000.

[0089] In some embodiments, a limiting buckle 5000 may also be designed to limit the pressing stroke of the pressing rod 3200 pressing the pump body 2000. Specifically, when the pump body 2000 is in a natural, unpressurized state, and the limiting buckle 5000 is engaged with the outer wall of the mounting area 1100, a set movable distance is left between the limiting buckle 5000 and the abutment of the pressing rod 3200. This movable distance is the limited pressing stroke.

[0090] Furthermore, by replacing different limit buckles 5000, different pressing strokes are limited. When limit buckles 5000 of different sizes are engaged with the outer wall of the installation area 1100, the pressing strokes are different. Therefore, different limit buckles 5000 can be selected according to different usage scenarios to control the liquid output, meet different usage needs, and avoid waste.

[0091] It is understandable that when designing limit buckles 5000 of different sizes, if the largest size limit buckle 5000 is designed to be snapped onto the outer wall of the installation area 1100, the two ends of the limit buckle 5000 will just snap onto the cover 1000 and the pressing structure, thus achieving the aforementioned function of the limit buckle 5000 in preventing the pressing rod 3200 from pressing the pump body 2000.

[0092] Regarding the implementation of limiting the pressing stroke, as an alternative, it can at least be designed as follows: the pressing stroke of the pressing rod 3200 pressing the pump body 2000 is limited by designing the length of the first guide protrusion 4202.

[0093] In one embodiment, the cover 1000 is provided with a support base 1200 for hinged connection of the push-button 3100. The support base 1200 is located on the surface of the cover 1000 facing the push-button 3100 and protrudes from the surface of the cover 1000. Specifically, the support base 1200 is disposed on the upper surface of the cover 1000. Further, the support base 1200 is disposed near the edge of the cover 1000.

[0094] Specifically, the push-button 3100 and the support base 1200 are connected by a second hinge structure. This second hinge structure includes a second hinge shaft 4301 and a second hinge area 4302. One of the second hinge shaft 4301 and the second hinge area 4302 is located on the side wall of the push-button 3100, and the other is located on the side wall of the support base 1200. In some examples, the second hinge shaft 4301 is located on the side wall of the support base 1200, and the second hinge area 4302 is located on the side wall of the push-button 3100. Specifically, two opposite inner side walls of the push-button 3100 are respectively provided with second hinge areas 4302, and two symmetrical positions on the side wall of the support base 1200 are respectively provided with second hinge shafts 4301. The two second hinge shafts 4301 are respectively hinged to the two second hinge areas 4302.

[0095] Furthermore, the sidewall of the second hinge area 4302 is formed with a first clearance opening, which is formed as a notch in the sidewall of the second hinge area 4302 so that the second hinge shaft 4301 can enter the second hinge area 4302.

[0096] In some alternative examples, the second hinge axis 4301 is disposed on the side wall of the push head 3100, and the second hinge area 4302 is disposed on the side wall of the support 1200.

[0097] In one embodiment, the support base 1200 is provided with a drainage area 1210, which penetrates the side wall of the support base 1200. The drainage area 1210 is used to drain residual liquid on the surface of the cover 1000. Specifically, the support base 1200 forms narrow spaces on the surface of the cover 1000, and residual liquid in these narrow spaces can be drained from the drainage area 1210 to prevent bacterial growth. When the container opening is located at the top, the support base 1200 is located on the upper side of the cover 1000, and the upper side of the cover 1000 slopes from the center to the periphery to facilitate downward flow of residual liquid.

[0098] In some examples, the support base 1200 includes two second upright plates 1222, which are disposed opposite to each other on the cover 1000. The two second upright plates 1222 are arranged parallel or at an angle to each other, and the push head 3100 is hinged to each of the two second upright plates 1222. Further, the support base 1200 includes a first upright plate 1221 located between the two second upright plates 1222. The first upright plate 1221 connects to each of the two second upright plates 1222, thereby improving the structural strength of the two second upright plates 1222. The first upright plate 1221 also connects to the cover 1000 to further improve the structural strength. Referring to the accompanying drawings, the support base 1200 forms a support structure with three sidewalls using the first upright plate 1221 and the two second upright plates 1222.

[0099] Referring to the accompanying drawings, a drainage area 1210 is disposed on the first upright plate 1221. The drainage area 1210 connects the inner and outer sides of the support base 1200 and extends to the point where the first upright plate 1221 connects to the cover 1000, so that liquid on the surface of the cover 1000 can flow out from the drainage area 1210. In some examples, the drainage area 1210 is set as a notch on the first upright plate 1221.

[0100] As an alternative implementation, the support base 1200 includes an arc-shaped upright plate, with the push head 3100 hinged to the arc-shaped upright plate. The arc-shaped upright plate is configured to have an arc of half a circle, or an arc greater than half a circle, or an arc less than half a circle.

[0101] Furthermore, the drainage area 1210 is located on the arc-shaped vertical plate. Specifically, the drainage area 1210 is a notch on the arc-shaped vertical plate.

[0102] As an alternative implementation, the push-button 3100 is provided with a support portion, which is hinged to the cover 1000. Specifically, the support portion is provided on the side of the push-button 3100 facing the cover 1000; or, the support portion extends and is formed on the push-button 3100 in the direction toward the cover 1000. It is understood that the push-button 3100 with the support portion is formed in a horizontal "L" shape.

[0103] Of course, as an alternative, the hinge between the push-button 3100 and the cover 1000 can also be designed as follows: the support part of the push-button 3100 is hinged to the support seat 1200 of the cover 1000.

[0104] In one implementation, the dispensing area 3300 is detachably disposed on the inner wall of the push head 3100 to allow for replacement with a new dispensing area 3300; or the dispensing area 3300 can be replaced with one having a dispensing port of a different shape, so that the liquid in the container is dispensed in the form of bubbles or fluid, thereby solving the problem of the pump body 2000 having a single dispensing form in related technologies. Alternatively, the dispensing area 3300 can be replaced with one having a dispensing port with a different function, so that the dispensing area 3300 has a specific function, such as good liquid cut-off capability, or the dispensing port has the function of a silicone valve.

[0105] On the other hand, the design of the dispensing area 3300 and the push head 3100 being detachable can also simplify the mold shape of the push head 3100 and the dispensing area 3300, making it easier to meet the mold opening requirements, facilitate mold opening, and reduce production costs.

[0106] Specifically, a first snap-fit ​​structure is provided between the inner wall of the push-button 3100 and the liquid dispensing area 3300. The first snap-fit ​​structure includes an elastic snap-fit ​​arm 4401 and a fastening area 4402. The elastic snap-fit ​​arm 4401 and the fastening area 4402 are snapped together to restrict the liquid dispensing area 3300 from moving away from the inner wall of the push-button 3100 toward the pressing rod 3200, and to enable a detachable connection between the liquid dispensing area 3300 and the push-button 3100.

[0107] Specifically, one of the elastic latching arm 4401 and the engaging area 4402 is located on the inner wall of the push-button 3100, and the other is located on the outer wall of the dispensing area 3300. In some examples, referring to the accompanying drawings, the elastic latching arm 4401 is located on the inner wall of the push-button 3100, and the engaging area 4402 is located on the outer wall of the dispensing area 3300. With the location of the dispensing port of the dispensing area 3300 as the front end of the dispensing area 3300, engaging areas 4402 are respectively provided on the outer walls of the left and right sides of the dispensing area 3300. Correspondingly, there are two elastic latching arms 4401, and the two elastic latching arms 4401 are respectively engaged with the two engaging areas 4402.

[0108] In some examples, the fastening area 4402 is provided with a through hole, and the elastic buckle arm 4401 passes through the through hole of the fastening area 4402. The elastic buckle arm 4401 is provided with a first buckle part, which protrudes from the side wall of the elastic buckle arm 4401 facing away from the liquid outlet area 3300. The first buckle part engages with the side wall of the lower side of the fastening area 4402, thereby fixing the liquid outlet area 3300 in the height direction.

[0109] It is understandable that the design of the first snap-fit ​​part engaging with the snap-fit ​​area 4402, rather than engaging with the outer wall of the liquid outlet area 3300, is based on the consideration that if the thickness of the liquid outlet area 3300 is large, the elastic snap-fit ​​arm 4401 would need to be designed with a corresponding length, and it is more convenient to design the first snap-fit ​​part of the elastic snap-fit ​​arm 4401 engaging with the snap-fit ​​area 4402.

[0110] Furthermore, an inclined guide surface is provided on the upper side of the fastening area 4402. The guide surface extends obliquely from the upper side of the fastening area 4402 to the inner wall of the through hole of the fastening area 4402. When the elastic buckle arm 4401 is engaged with the fastening area 4402, it can enter the through hole along the guide surface.

[0111] In some alternative examples, the first snap-fit ​​portion protrudes from the sidewall of the elastic snap-fit ​​arm 4401 facing the liquid outlet area 3300, and the first snap-fit ​​portion engages with the sidewall of the lower side of the engagement area 4402.

[0112] In one embodiment, a second locking structure is provided between the inner wall of the push-button 3100 and the liquid dispensing area 3300. The second locking structure includes a first limiting protrusion 4501 and a recessed first limiting area 4502. The first limiting protrusion 4501 is connected to the first limiting area 4502 to restrict the movement of the liquid dispensing area 3300 on the inner wall of the push-button 3100, thereby preventing the liquid dispensing area 3300 from shifting position on the inner wall of the push-button 3100. It can be understood that, with the cooperation of the second locking structure and the first locking structure, the liquid dispensing area 3300 can be fixed to the inner wall of the push-button 3100.

[0113] Specifically, one of the first limiting protrusion 4501 and the first limiting area 4502 is disposed on the inner sidewall of the push-button 3100, and the other is disposed on the sidewall of the dispensing area 3300 facing the inner sidewall of the push-button 3100. In some examples, referring to the accompanying drawings, the first limiting protrusion 4501 is disposed on the upper sidewall of the dispensing area 3300, and the first limiting area 4502 is disposed on the inner sidewall of the push-button 3100. The first limiting protrusion 4501 is configured as a reinforcing rib of the protrusion, and after the first limiting protrusion 4501 and the first limiting area 4502 are engaged, the dispensing area 3300 is restricted from moving back and forth on the inner sidewall of the push-button 3100.

[0114] Furthermore, the second locking structure also includes a second limiting protrusion 4601 and a recessed second limiting region. The second limiting protrusion 4601 is connected to the second limiting region to restrict the movement of the dispensing area 3300 on the inner wall of the push-button 3100. The directions of movement of the dispensing area 3300 restricted by the mutually locking first limiting protrusion 4501 and first limiting region 4502, as well as the mutually locking second limiting protrusion 4601 and second limiting region, are different. In this case, the second locking structure can restrict the movement of the dispensing area 3300 in two different directions on the inner wall of the push-button 3100, thereby further preventing the positional displacement of the dispensing area 3300.

[0115] It is understood that one of the second limiting protrusion 4601 and the second limiting area is disposed on the inner sidewall of the press head 3100, and the other is disposed on the sidewall of the dispensing area 3300 facing the inner sidewall of the press head 3100. In some examples, referring to the accompanying drawings, the second limiting protrusion 4601 is disposed on the upper sidewall of the dispensing area 3300, and the second limiting area is disposed on the inner sidewall of the press head 3100. The second limiting protrusion 4601 is configured as a reinforcing rib of the protrusion, and after the second limiting protrusion 4601 and the second limiting area are engaged, the dispensing area 3300 is restricted from moving left and right on the inner sidewall of the press head 3100. This allows the second engaging structure and the first engaging structure to fix the position of the dispensing area 3300 on the inner sidewall of the press head 3100 in the left-right, front-back, and up-down directions, preventing displacement.

[0116] In some examples, on the upper sidewall of the liquid outlet area 3300, the reinforcing ribs formed by the first limiting protrusion 4501 are arranged laterally with left and right as the horizontal direction and front and back as the vertical direction, while the reinforcing ribs formed by the second limiting protrusion 4601 are arranged vertically. Referring to the attached drawings, the inner sidewall of the push-button 3100 is provided with at least two supporting protrusions 3130, which are arranged vertically.

[0117] Furthermore, the support protrusion 3130 is provided with a recessed opening to form a first limiting area 4502. The upper sidewall of the liquid outlet area 3300 abuts against the support protrusion 3130, and the first limiting protrusion 4501 is connected to the opening of the support protrusion 3130. The second limiting protrusion 4601 fits against the side of the support protrusion 3130. Referring to the attached drawings, the abutting surface of the support protrusion 3130 that abuts against the liquid outlet area 3300 is set as an inclined surface. From the front end to the rear end of the liquid outlet area 3300, the inclined surface gradually approaches the inner sidewall of the push-button 3100, so that the liquid outlet area 3300 is inclined against the inner sidewall of the push-button 3100, forming a downward inclined state of the liquid outlet, which facilitates liquid dispensing.

[0118] In one embodiment, the dispensing tube 3400 is made of a soft material to form a flexible hose. The dispensing tube 3400 is convenient to bend when positioned between the dispensing area 3300 and the pressing rod 3200, and it can deform and bend when the pressing head 3100 is pressed. Specifically, the dispensing tube 3400 is a silicone tube.

[0119] Furthermore, the outlet pipe 3400 is provided with an elastic support structure, which supports and shapes the side wall of the outlet pipe 3400 so that the outlet pipe 3400 remains tubular when under pressure, preventing the outlet pipe 3400 from folding and ensuring that the liquid in the outlet pipe 3400 can flow smoothly.

[0120] In some examples, the dispensing tube 3400 is telescopic, which increases its deformability when the dispensing tube 3400 and the pressing head 3100 are arranged, preventing excessive pulling of the dispensing tube 3400 when the pressing head 3100 rotates, preventing the dispensing tube 3400 from becoming loose from the dispensing area 3300 and the pressing rod 3200, and preventing leakage. Specifically, the elastic support structure is spiral-shaped, which has both bending and telescopic deformation capabilities, and provides support and shaping for the sidewall of the dispensing tube 3400. Further, the elastic support structure is disposed on the inner or outer sidewall of the dispensing tube 3400, and is fixedly connected to the sidewall of the dispensing tube 3400; or, the elastic support structure is disposed within the sidewall of the dispensing tube 3400.

[0121] In some alternative examples, the outlet pipe 3400 is set as a bellows.

[0122] In one embodiment, the inner wall of the push head 3100 is provided with a bayonet structure 3120. Referring to the attached drawings, the bayonet structure 3120 is located at the rear end of the liquid outlet area 3300 on the inner wall of the push head 3100, and the bayonet structure 3120 engages with the outer wall of the liquid outlet tube 3400.

[0123] On the one hand, the latch structure 3120 can tighten and fix the liquid outlet tube 3400 to a certain extent, preventing the liquid outlet tube 3400 from sagging. On the other hand, under the latch structure 3120, part of the outer wall of the liquid outlet tube 3400 is attached to the inner wall of the push head 3100. When the push head 3100 is pressed, the bent liquid outlet tube 3400 generates a rebound force on the push head 3100. After the user releases the pressure on the push head 3100, the elastic force of the liquid outlet tube 3400 can help the push head 3100 quickly rebound and reset.

[0124] It is understood that the bayonet structure 3120 has an opening with a width smaller than the outer diameter of the outlet pipe 3400, and the opening faces downwards. The opening of the bayonet structure 3120 can lock the outlet pipe 3400. Referring to the attached drawing, the bayonet structure 3120 is shaped like a tiger's mouth.

[0125] In one embodiment, the liquid outlet channel of the pressing rod 3200 forms an outlet on the end face of the pressing rod 3200 facing the pressing head 3100. The outlet is located in the middle of the end face of the pressing rod 3200. The liquid outlet pipe 3400 is connected to the outlet. The liquid outlet pipe 3400 bends from the end of the pressing rod 3200 toward the liquid outlet area 3300 and connects to the liquid outlet area 3300.

[0126] Referring to the attached drawings, a retaining edge 3220 is provided on the end face of the pressing rod 3200 facing the pressing head 3100. The retaining edge 3220 is formed into an arc-shaped plate and protrudes from the end face of the pressing rod 3200. When the pressing head 3100 applies pressure to the pressing rod 3200, the retaining edge 3220 abuts against the inner sidewall of the pressing head 3100.

[0127] Furthermore, the end of the retaining edge 3220 facing the press head 3100 is provided with a second clearance opening 3221 for avoiding the liquid outlet tube 3400. The second clearance opening 3221 is formed as a notch and is U-shaped. When the inner wall of the press head 3100 presses the retaining edge 3220 of the press rod 3200, the liquid outlet tube 3400 is located at the second clearance opening 3221, thereby preventing the inner wall of the press head 3100 from squeezing the liquid outlet tube 3400, preventing the liquid outlet tube 3400 from being flattened, and ensuring smooth liquid dispensing. It can be understood that the retaining edge 3220 with the second clearance opening 3221 on the press rod 3200 can provide space for the bending and extension of the liquid outlet tube 3400.

[0128] In some alternative examples, it can also be designed such that at least two upright plates or columns are spaced apart on the end face of the first end of the pressing rod 3200, and the area between adjacent upright plates or columns serves as a notch to avoid the liquid outlet pipe 3400.

[0129] As one implementation, the pressing area 3110 is set with a concave arc shape on the surface of the pressing head 3100 to facilitate finger pressing and prevent finger position displacement during pressing.

[0130] In one implementation, the pressing area 3110 is provided with an anti-slip structure to increase the friction between the finger and the pressing area 3110 and prevent the finger from slipping during pressing. Specifically, the anti-slip structure includes anti-slip patterns, which are grooves or ridges. Referring to the attached drawings, multiple anti-slip patterns are arranged along concentric circular trajectories.

[0131] In some examples, the anti-slip texture can also be designed as a crisscross pattern, or as multiple parallel lines.

[0132] Understandably, in some examples, the anti-slip structure is located on the concave arc surface of the pressing area 3110.

[0133] As an alternative, some examples of anti-slip structures can also be designed as follows: the anti-slip structure includes anti-slip bumps, an array of anti-slip bumps, or anti-slip bumps arranged along a concentric circle trajectory.
