[0033] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0034] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0035] In the description of the present invention, if there is a description of first and second, it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0036] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0037] like Figures 1 to 8 As shown, the discharging component according to an embodiment of the present invention includes: a shell 100, a discharging piece 200, a button 300, and a discharging nozzle 400. The discharging piece 200 is arranged in the shell 100, and the discharging piece 200 includes a discharging channel 201 for discharging materials; the button 300 is movably arranged in the shell 100; the button 300 and the discharging nozzle 400 are connected by a linkage structure, and the discharging nozzle 400 is provided with a blocking structure corresponding to the discharging channel 201 and a connecting channel that can pass through the discharging nozzle 400. When the button 300 is not pressed, the linkage structure can position the discharging nozzle 400 in a blocking position, and the blocking structure cuts off the discharging channel 201. When the button 300 is pressed, the button 300 can drive the discharging nozzle 400 to move and open the discharging channel 201 through the linkage structure, and the material output by the discharging channel 201 can be output through the connecting channel.

[0038] Through the above structure, the material can be normally output when the button 300 is pressed. When not in use, the discharge channel 201 can be blocked, which can better protect the material in the pump and reduce the occurrence of pollution.

[0039] Specifically, one end of the discharge channel 201 is connected to the conveying channel of the pump body, and the button 300 is connected to the piston assembly in the pump body. When the button 300 is pressed, the material in the pump body can be transported to the discharge channel 201 through the conveying channel, and then output by the discharge nozzle 400. When the button 300 is reset by the elastic part, the material in the container can be automatically sucked into the pump body. At the same time, the sealing structure of the discharge nozzle 400 blocks the discharge channel 201, thereby reducing the occurrence of external bacteria, insects, dust, etc. entering the pump body, and can effectively protect the material in the pump body.

[0040] like Figures 1 to 4 As shown, in some embodiments of the present invention, when the button 300 is not pressed, the discharge nozzle 400 is partially or completely stored in the shell 100, reducing the occupied space and facilitating carrying. When the button 300 is pressed, the discharge nozzle 400 protrudes from the shell 100 for easy use.

[0041] Specifically, the housing 100 is provided with a through hole for the discharge nozzle 400 to pass through.

[0042] It is conceivable that, in some embodiments of the present invention, the discharge nozzle 400 may be configured not to extend from the shell 100 and may be a fully built-in configuration, which will not be described in detail here.

[0043] like Figure 2 、 Figure 4 、 Figure 6 As shown, in some embodiments of the present invention, the discharge member 200 includes a discharge pipe 210, the discharge channel 201 is arranged in the discharge pipe 210, and the discharge nozzle 400 is mounted on the discharge pipe 210 and can slide along the axial direction of the discharge pipe 210 to realize the telescopic setting of the discharge nozzle 400.

[0044] Specifically, a cavity is provided in the discharge nozzle 400 for inserting the discharge tube 210, and a sliding fit is formed. In conjunction with the linkage structure, when the button 300 is pressed or released, the discharge nozzle 400 can be driven to move in the axial direction of the discharge tube 210, thereby realizing switching between the open position and the blocked position.

[0045] It is conceivable that, in some embodiments of the present invention, the discharge nozzle 400 can be inserted into the discharge channel 201 and can also achieve the function of sliding and retracting.

[0046] It is conceivable that in some embodiments of the present invention, the discharge nozzle 400 can also be rotatably set in the shell 100 or the discharge piece 200. When rotated to the open position, the connecting channel of the discharge nozzle 400 is aligned with and connected to the discharge channel 201. When rotated to the blocked position, the connecting channel of the discharge nozzle 400 deviates from the discharge channel 201, thereby blocking the discharge channel 201. At this time, pressing the button 300 can drive the discharge nozzle 400 to rotate through linkage structures such as inclined surfaces and guide grooves.

[0047] It should be noted that, in some embodiments of the present invention, after pressing the button 300 and then releasing the button 300 , the button 300 can be reset by pressing an elastic member of the pump, such as a spring, an elastomer, or the like.

[0048] like Figure 5 、 Figure 6 As shown, in some embodiments of the present invention, a baffle 410 is provided at the outer end of the discharge nozzle 400 to form a blocking structure, and a plurality of through holes 420 are provided at the edge of the baffle 410 to form a connecting channel, and the blocking and connecting functions are respectively realized by the baffle 410 and the through holes 420.

[0049] Specifically, the discharge nozzle 400 is a tubular structure, one end of which is open and is sleeved on the discharge pipe 210, so that the discharge nozzle 400 is connected to the discharge pipe 210 and forms a sliding fit structure. A baffle 410 is provided at the other end of the discharge nozzle 400. The baffle 410 corresponds to the discharge pipe 210 and can block the discharge pipe 210. A number of through holes 420 are distributed in a ring at the edge of the baffle 410. When the baffle 410 opens the discharge pipe 210, the material in the discharge pipe 210 can flow into the discharge nozzle 400 and be sent out through the through holes 420.

[0050] In the present invention, the baffle 410 is arranged at the outer end of the discharge nozzle 400, so that when the baffle 410 blocks the discharge pipe 210, the material remaining at the discharge nozzle 400 can be greatly reduced, thereby reducing the amount of material directly exposed to the air.

[0051] Specifically, the material remaining at the discharge nozzle 400 is only the material remaining in the through hole 420 , so the amount is relatively small and will not cause significant pollution, so it is more hygienic and safe to use.

[0052] It is conceivable that the baffle may also be disposed in the middle of the discharge nozzle 400, etc., which will not be described in detail here.

[0053] It is conceivable that in some embodiments of the present invention, the blocking structure may also be other structures. For example, the discharge nozzle 400 is a tubular structure, and a plug corresponding to the discharge channel 201 is arranged in the discharge nozzle 400. The plug may be a spherical or conical structure, etc. There is a gap between the inner wall of the discharge nozzle 400 and the plug to form a connecting channel for material to pass through when the discharge channel 201 is not blocked.

[0054] Specifically, the inner wall of the discharge nozzle 400 and the plug may be connected by a plurality of spaced and annularly distributed connecting strips, so that a gap is formed between the inner wall of the discharge nozzle 400 and the plug.

[0055] In some embodiments of the present invention, the discharge nozzle 400 can be slidably set on the shell 100 or the discharge piece 200, and the linkage structure includes a guide part 430 and a guide groove 310 for the guide part 430 to be inserted and slide. One of the guide part 430 and the guide groove 310 is set on the discharge nozzle 400, and the other is set on the button 300. When the button 300 moves up and down, the discharge nozzle 400 can be guided to slide through the cooperation of the guide groove 310 and the guide part 430.

[0056] Of course, in the specific implementation process, the linkage structure can also be a pushing structure, such as setting a protrusion on the button 300 and a corresponding pushing portion on the discharge nozzle 400. When the button 300 is pressed down, the protrusion can push the pushing portion, thereby driving the discharge nozzle 400 to move. At this time, the discharge nozzle 400 can be configured with a spring for reset.

[0057] like Figure 5 、 Figure 6 As shown, in some embodiments of the present invention, two guide parts 430 are configured and respectively arranged on both sides of the discharge nozzle 400, and the guide groove 310 and the guide part 430 are configured one-to-one correspondingly and arranged on the button 300, so that the drive of the discharge nozzle 400 is more stable and reliable.

[0058] Specifically, the guide parts 430 are symmetrically distributed on both sides of the discharge nozzle 400, and there are two guide grooves 310 distributed on both sides of the button 300, so that the linkage structure between the button 300 and the discharge nozzle 400 is more balanced and reasonable, and the driving is smoother and more stable.

[0059] It is conceivable that the guide portion 430 and the guide groove 310 can also be configured as a single unit, which can also satisfy the function of linkage driving.

[0060] It is conceivable that, in some embodiments of the present invention, the guide portion 430 may be provided on the button 300 , and the guide groove 310 may be provided on the discharge nozzle 400 , which may also satisfy the function of linkage driving.

[0061] like Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 As shown, in some embodiments of the present invention, the guide portion 430 is provided on the discharge nozzle 400, and the guide groove 310 is provided on the button 300. The guide groove 310 includes an inclined slide section 311 for guiding the discharge nozzle 400 to slide, so as to achieve the blocking and opening of the discharge channel 201.

[0062] Specifically, the oblique chute section 311 extends from top to bottom and is inclined in a direction opposite to the sliding out direction of the discharge nozzle 400 , so that when the button 300 is pressed down, the discharge nozzle 400 can be driven to slide out.

[0063] It is conceivable that, in a specific implementation, the oblique chute section 311 may also be a curved chute or a special-shaped chute.

[0064] In some embodiments of the present invention, the guide portion 430 is cylindrical and has good sliding performance, making the driving smoother.

[0065] It is conceivable that the guide portion 430 may also be a square column, etc., which will not be described in detail here.

[0066] like Figure 5 、 Figure 6 、 Figure 7 、 Figure 8As shown, in some embodiments of the present invention, the guide groove 310 includes a straight groove section 312 extending along the pressing direction of the button 300. The straight groove section 312 can keep the discharge nozzle 400 in a position connected to the discharge channel 201 when the button 300 moves downward, so as to facilitate continuous output of materials.

[0067] Specifically, when the pump body has a large internal volume (a single press can deliver a large amount of material), to avoid affecting normal material delivery, the discharge channel 201 needs to be opened when the button 300 moves downward for a short time. Continued downward pressure on the button 300 maintains the position of the discharge nozzle 400 via the straight groove section 312, allowing continuous material delivery. Furthermore, the provision of the straight groove section 312 reduces the extension distance of the discharge nozzle 400 (when the button travels a long distance), preventing a large amount of material from accumulating or remaining in the discharge nozzle 400.

[0068] like Figure 6 As shown, in some embodiments of the present invention, the discharge member 200 is provided with a positioning portion 220 abutting against the shell 100, the button 300 is arranged above the discharge member 200 and is provided with a driving portion 320 extending downward, and the positioning portion 220 is provided with a hole 221 for the driving portion 320 to pass through, so that the driving portion 320 can move downward to control the pump body.

[0069] Specifically, the driving portion 320 is used to connect or abut against components of the pump body.

[0070] Reference Figures 1 to 4 The pressing pump according to the second embodiment of the present invention includes a pump body and a discharge component according to any embodiment of the first aspect of the present invention. The discharge component can better protect the material in the pump body, making it more hygienic and safe to use.

[0071] Specifically, such as Figure 2 、 Figure 4As shown, the pump body includes a pump housing 510, a one-way ball 520, a secondary column 530, a piston 540, a main column 550, a lock cover 560, a connecting rod 570, and a spring 590, wherein the housing 100 and the pump housing 510 are fixed on the bottle cap 580, the discharge piece 200, the connecting rod 570, and the main column 550 are connected in sequence, the secondary column 530 and the piston 540 are connected to the lower end of the main column 550, the bottom of the pump housing 510 is the feed port, the one-way ball 520 is movably arranged at the feed port, the piston 540 is located in the pump housing 510, and a silo is formed in the pump housing 510, and a connecting rod 570 and the main column 550 are provided with a channel connecting the silo and the discharge port. The pumping channel is connected to the channel 201. Pressing the button 300 can drive the connecting rod 570, the main column 550, the auxiliary column 530 and the piston 540 to move downward, the volume of the silo decreases, the pressure increases, and the one-way ball 520 blocks the feed port, so that the silo material enters the discharge channel 201 through the pumping channel for output. Release the button 300, the button 300, the connecting rod 570, the main column 550, the auxiliary column 530 and the piston 540 are reset due to the force of the spring 590. At this time, the volume of the silo increases, forming a negative pressure. The one-way ball 520 opens the feed port, and the silo sucks in the material from the feed port. The material refills the silo, and the pumping function can be realized.

[0072] Of course, the invention is not limited to the above-mentioned embodiments. Those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
