[0051] In the prior art, syrups and other slurries are stored in containers. When the syrup needs to be added to food (such as tea, cakes, bread, etc.), the operator will open the container cover, scoop out the slurry with a spoon, and then add it to the food.

[0052] Example 1

[0053] Combination Figures 1 to 5 As shown, the utility model provides a syrup pump, which includes: a base 10, which has a cavity, the cavity is divided into an air cavity 10b and a material cavity 10c which are interconnected, the material cavity 10c is provided with a feed port 111 and a discharge port 112; a feed plugging member 113, which is movably arranged at the feed port 111; a discharge plugging member 114, which is movably arranged at the discharge port 112; a driving mechanism 20, which is movably arranged in the air cavity 10b, and pressurizes the gas in the air cavity 10b under the action of an external force, so as to drive the feed plugging member 113 to plug the feed port 111 and drive the discharge plugging member 114 to open the discharge port 112, so that the slurry in the material cavity 10c is discharged through the discharge port 112.

[0054] Specifically, the syrup pump of the present application is used in conjunction with a container, in which syrup and other slurries are stored. When the syrup pump is installed on the container, the feed port 111 needs to be immersed in the slurry in the container. When the syrup pump is used for the first time, there is no slurry in the material cavity 10c, and the drive mechanism 20 is in the initial position at this time. The operator applies an external force to the drive mechanism 20, and the drive mechanism 20 pressurizes the gas in the air cavity 10b under the action of the external force, and the volume of the air cavity 10b gradually decreases, so that the gas in the air cavity 10b flows into the material cavity 10c. During the gas flow, the feed plugging member 113 is driven to plug the feed port 111, so that the slurry in the container cannot enter the material cavity 10c through the feed port 111, and the discharge plugging member 114 is driven to open the discharge port 112, so that the gas in the material cavity 10c is discharged through the discharge port 112.

[0055] The operator stops applying external force to the drive mechanism 20, and the drive mechanism 20 is reset to the initial position. During the reset process, the discharge blocking member 114 loses the thrust of the gas and moves downward under its own gravity, blocking the discharge port 112. At the same time, the volume of the air cavity 10b gradually increases with the reset of the drive mechanism 20, causing the air pressure in the air cavity 10b and the material cavity 10c to decrease and form a negative pressure. The discharge blocking member 114 continues to block the discharge port 112 under the negative pressure, while the feed blocking member 113 moves upward to open the feed port 111, allowing the slurry in the container to enter the material cavity 10c.

[0056] The operator applies external force to the driving mechanism 20 again, and the driving mechanism 20 applies pressure to the gas in the air cavity 10b under the action of the external force. The volume of the air cavity 10b gradually decreases, so that the gas in the air cavity 10b flows into the material cavity 10c and pushes the slurry in the material cavity 10c to move toward the discharge port 112. During the flow of gas, the feed blocking member 113 is driven to block the feed port 111, so that the slurry in the container cannot enter the material cavity 10c through the feed port 111, and the discharge blocking member 114 opens the discharge port 112, so that the slurry in the material cavity 10c is discharged through the discharge port 112.

[0057] Compared with the prior art, when the syrup pump of the present application is used, when an external force is applied to the driving mechanism 20, the driving mechanism 20 pressurizes the gas in the air cavity 10b, the feed blocking member 113 blocks the feed port 111, and the discharge blocking member 114 opens the discharge port 112, so that the slurry in the cavity 10c is discharged through the discharge port 112, thereby achieving the situation that there is no need to open the container cover 420 during the discharge process, reducing the contact between the slurry and the external environment, and preventing the slurry from being contaminated and deteriorated.

[0058] In this embodiment, the driving mechanism 20 includes: a pushing member 210, which is arranged in the cavity and is used to change the size of the air cavity 10b; a driving member 220, which is arranged outside the air cavity 10b; a connecting shaft 230, one end of which is connected to the pushing member 210, and the other end of the connecting shaft 230 is connected to the driving member 220.

[0059] The pusher 210 is disposed in the cavity, and the pusher 210 is sealed and connected to the inner wall of the cavity. The operator applies external force to the driving member 220 to make the driving member 220 move downward. Since the driving member 220 is connected to the pushing member 210 through the connecting shaft 230, the pushing member 210 moves downward synchronously, reducing the volume of the air cavity 10b, compressing the gas in the air cavity 10b and causing the gas to move toward the material cavity 10c, thereby pushing the slurry out of the material cavity 10c. When the operator stops applying external force to the driving member 220, the driving member 220 moves upward, and the pushing member 210 moves upward synchronously, increasing the volume of the air cavity 10b. The volume of the air cavity 10b gradually increases with the resetting of the driving mechanism 20, resulting in a decrease in the air pressure in the air cavity 10b and the material cavity 10c and forming a negative pressure. The discharge blocking member 114 blocks the discharge port 112 under the action of negative pressure, while the feed blocking member 113 moves upward to open the feed port 111, so that the slurry in the container enters the material cavity 10c.

[0060] The above-mentioned method of resetting the driving member 220 by upward movement when the operator stops applying external force to the driving member 220 can be reset by the operator manually pulling the driving member 220 upward, or by the elastic force of the spring member 250 described below. In the above-mentioned design, the driving member 220 is preferably a handle for the operator to grasp.

[0061] Preferably, at least one sealing ring is provided on the outer peripheral side of the pushing member 210, and the sealing ring is in contact with the inner wall of the cavity. In this embodiment, the sealing ring is used to achieve sealing to prevent the gas in the air cavity 10b from leaking through the gap between the pushing member 210 and the cavity without affecting the movement of the pushing member 210.

[0062] In one embodiment, the driving mechanism 20 also includes: a positioning member 240, whose outer peripheral side is clamped in a preset position in the cavity; the positioning member 240 is provided with a through hole 241, and one end of the connecting shaft 230 passes through the through hole 241 to be connected to the pushing member 210; a spring member 250, which is sleeved outside the connecting shaft 230, and the spring member 250 is restricted between the positioning member 240 and the driving member 220.

[0063] In this embodiment, the operator applies an external force to the driving member 220, so that the driving member 220 moves downward and drives the pushing member 210 to move downward synchronously. Since the outer peripheral side of the positioning member 240 is clamped at a preset position in the cavity, the outer peripheral side of the positioning member 240 cannot move downward and remains at the preset position. As the driving member 220 moves downward, the spring member 250 will be compressed by the driving member 220 and the positioning member 240, accumulating elastic potential energy. When the operator stops applying external force to the driving member 220, the compressed spring member 250 elastically deforms in the absence of external force, providing an upward force for the driving member 220, pushing the driving member 220 to return to its initial position.

[0064] It should be noted that, regarding the implementation method of clamping the outer peripheral side of the positioning member 240 at the preset position in the cavity, the inner diameter of the cavity can be designed. For example, in combination with this embodiment, the outer diameter of the positioning member 240 is designed to be d2, and the inner diameter of the cavity at the preset position is d2, and the inner diameter of the cavity below the preset position is designed to be d1, wherein d1<d2. Preferably, the inner diameter of the cavity above the preset position is designed to be d3, wherein d3≥d2. Through the above design, this embodiment can realize the assembly of the positioning member 240 to the preset position in the cavity and complete the clamping limit.

[0065] Furthermore, the driving mechanism 20 further includes a limiting sleeve 260, which is sleeved outside the spring member 250; a limiting portion 261 is provided at one end of the limiting sleeve 260 close to the pushing member 210, and an end of the limiting sleeve 260 close to the driving member 220 abuts against the spring member 250; the cavity is provided with a removal opening 115, and a locking member 430 for limiting the limiting portion 261 from leaving the cavity is installed at the removal opening 115. In this embodiment, by sleeved outside the spring member 250, the spring member 250 is protected to prevent the spring member 250 from being exposed and damaged, and the spring member 250 is also limited. In addition, one end of the limiting sleeve 260 close to the driving member 220 abuts against the spring member 250, so that when the driving member 220 moves downward, the limiting sleeve 260 can be used to compress the spring member 250, and better cover the spring member 250 to prevent the spring member 250 from being exposed. In addition, a locking member 430 for limiting the limiting portion 261 from leaving the cavity is installed at the removal opening 115. When the limiting sleeve 260 moves upward and is about to make a stroke beyond the expected design, the limiting portion 261 abuts against the locking member 430, and the locking member 430 is used to limit the position of the limiting sleeve 260 to prevent it from leaving the cavity.

[0066] Furthermore, the present application can complete the assembly of the pushing member 210 and the positioning member 240 and the cleaning of the cavity through the disassembly port 115 .

The length direction of the connecting shaft 230 is the same as the length direction of the cylinder 120.

[0068] It should be noted that, in this embodiment, the second cavity 120a is vertically arranged with the first cavity 110a, so that the present application can drive the driving member 220 to move downward by applying a downward external force to the driving member 220. In other variations of the embodiments, the second cavity 120a can also be inclined with the first cavity 110a, or parallel to each other, and the present application does not limit this.

[0069] In this embodiment, the air cavity 10b and the discharge port 112 are both provided with a limit member 116, and the limit member 116 is respectively located above the feed sealing member 113 and the discharge sealing member 114; the limit member 116 is utilized to limit the upward movement of the feed sealing member 113 and the discharge sealing member 114 to prevent the feed sealing member 113 and the discharge sealing member 114 from excessive movement and causing disturbance in the cavity, thereby causing the syrup pump to fail to operate normally.

[0070] Preferably, mounting holes are provided at corresponding positions of the air cavity 10b and the discharge port 112, and the limiting member 116 is a limiting column, which is inserted into the mounting hole to complete the installation and fixation of the limiting member 116; this embodiment can facilitate the mold opening and production of the base 10 in the above manner, and the limiting column is sealed and connected to the mounting hole, so that the slurry in the container cannot flow into the cavity through the gap between the limiting column and the mounting hole, thereby avoiding affecting the quantitative discharge of the slurry in this application.

[0072] In this embodiment, the material cavity 10c is also provided with a core-pulling opening 117, and the core-pulling opening 117 is provided with a detachable closure 118; in the production and manufacturing of the base 10 of this embodiment, since the second cavity 120a and the first cavity 110a are vertically arranged, it is necessary to set two core-pulling locations, such as using the removal opening 115 and the core-pulling opening 117 for core-pulling, and in order to prevent the slurry in the material cavity 10c from leaking from the core-pulling opening 117, the closure 118 is provided in this embodiment to complete the closure. Moreover, the closure 118 is detachably connected to the core-pulling opening 117, so that after the closure 118 is removed, it is convenient for the operator to clean the cavity through the core-pulling opening 117, the removal opening 115, the feed opening 111 and the discharge opening 112.

[0073] Preferably, the closing member 118 includes a bolt and a bolt sleeve, the bolt sleeve is provided with an internal thread matching the bolt, and the bolt sleeve is fixedly connected to the core-pulling opening 117 .
