Description

Technical Field

[0001] This application relates to the field of alcohol production technology, and in particular to a liquid sprayer and liquid spraying device. Background Technology

[0002] In the field of baijiu brewing technology, the feeding of the mash into the fermentation pit is one of the key steps in the production process. This process requires the addition of a large amount of tail liquor to the mash. Its main functions include lowering the temperature of the mash entering the pit, replenishing the moisture needed by the mash, and maintaining suitable environmental conditions for the growth and reproduction of microorganisms. The uniformity of the mixing between the mash and the tail liquor directly affects the fermentation effect in the pit, and thus has a significant impact on the quality of the final product.

[0003] In existing technologies, the common practice of pouring tail liquor is usually done manually. Specifically, workers typically use ladles to pour the liquor from containers into the fermentation pit. However, manual labor is physically demanding, and workers' efficiency tends to decrease after such strenuous work, resulting in poor mixing of the liquor and mash, ultimately affecting the quality of the product.

Detailed Implementation

[0019] To make the technical solutions and advantages of this application clearer, the embodiments and related technical content of this application will be further described in detail below with reference to the accompanying drawings and text description. It should be understood that the embodiments described below are only used to explain the technical solutions of the embodiments of this application and are not intended to limit more possible implementations of this application.

[0020] It should be noted that relational terms such as "first" and "second" appearing in this document are used only to distinguish things, states, or actions, and do not necessarily indicate or imply relative importance or order. The terms "including," "comprising," or any other variations thereof are used to indicate non-exclusive inclusion, and the included objects may not be limited to those listed in this document. The terms "multiple" or other variations are used to indicate that the number of objects is two or more.

[0021] In a first aspect, embodiments of this application provide a wine sprayer that can be used to spray wine to a designated location, and is particularly suitable for spraying wine onto mash during the wine production process.

[0022] like Figure 1 As shown, the wine sprayer provided in the embodiments of this application mainly includes a sealing cap 100 and an air pump assembly 200. The sealing cap 100 is used to seal the opening of the wine container (not shown in the figure); the air pump assembly 200 includes an air pump 210, a pedal 220, an air supply pipe 230, and a first liquid outlet pipe 240; the pedal 220 is used to convert the pressure from the outside into driving force to drive the air pump 210 to output gas; the first end of the air supply pipe 230 is connected to the output end of the air pump 210 to receive gas; the second end of the air supply pipe 230 passes through the sealing cap 100 and is used to connect to the inside of the wine container; the first liquid outlet pipe 240 passes through the sealing cap 100 and is used to transfer the pressurized wine from the wine container to the outside.

[0023] The interior of the wine container can be used to hold wine, and the wine container may include an opening for pouring and dispensing wine. The shape of the sealing cap 100 can match the shape of the opening of the wine container; the shape of the sealing cap 100 can be square, round, or irregular, etc., without particular limitation. It is understood that matching the shape of the sealing cap 100 to the shape of the opening of the wine container means that the contact surface of the sealing cap 100 with the opening matches, but the shape of the sealing cap 100 itself does not need to match the shape of the opening. The sealing cap 100 can be used to seal the opening of the wine container, so that the interior of the wine container is in a closed state. The edge of the sealing cap 100 can be made of a material with a certain degree of elasticity, such as rubber or silicone, which is beneficial to achieving good sealing performance. It is understood that sealing the opening of the wine container by the sealing cap 100 means that the contact portion between the sealing cap 100 and the edge of the opening is sealed, and the sealing cap 100 itself may have holes.

[0024] The air pump 210 can be a component that generates gas pressure. In some specific embodiments, multiple air pumps 210 can be provided simultaneously, and multiple air pumps 210 can be arranged side by side. The pedal 220 can be a component for the user to apply pressure. The pedal 220 can be made of materials such as plastic or metal. The pedal 220 can convert the pressure applied by the user onto it into a driving force to drive the air pump 210 to output gas.

[0025] It is understood that the specific connection method and working principle of the air pump 210 and the pedal 220 can adopt existing technology. For example, the air pump 210 may include a sealed cylindrical cylinder, a piston that can reciprocate within the cylinder, a connecting rod connecting the pedal 220 and the piston, an intake valve that only allows air to enter the cylinder, an exhaust valve that only allows air to exit the cylinder, and a return spring that pushes the pedal 220 and the piston back to their initial positions.

[0026] When the user presses the pedal 220, the connecting rod pushes the piston towards the bottom of the cylinder, compressing the air inside and increasing the air pressure. This high-pressure air opens the exhaust valve, allowing air to be released. When the foot is lifted, the return spring causes the pedal 220 and piston to return to their initial positions. The piston retracts, creating negative pressure within the cylinder. External air pressure then opens the intake valve, allowing air to re-enter the cylinder.

[0027] The gas delivery tube 230 can be a hollow tubular structure for conveying gas, and its material can be a flexible material (e.g., silicone, rubber, etc.). The end of the gas delivery tube 230 closest to the air pump 210 is the first end of the gas delivery tube 230, and the end furthest from the air pump 210 is the second end. The first end of the gas delivery tube 230 is connected to the output end of the air pump 210 to receive the gas blown out by the air pump 210. The second end of the gas delivery tube 230 passes through the sealing cap 100 and extends into the interior of the wine container, allowing the gas received from the air pump 210 to flow into the interior of the wine container. Optionally, the second end of the gas delivery tube 230 may not extend into the wine to prevent backflow of the wine from the gas delivery tube 230.

[0028] The first outlet tube 240 can also be a hollow tubular structure, passing through the sealing cap 100. One end of the first outlet tube 240 extends into the liquid inside the liquid container, while the other end extends through the sealing cap 100 to the outside, so as to facilitate the discharge of liquid from the inside of the liquid container. Optionally, the end of the first outlet tube 240 that extends into the liquid can extend to the bottom of the liquid container, so as to discharge as much liquid as possible from the inside of the liquid container.

[0029] Understandably, the wine sprinkler uses pedal 220 to drive air pump 210 to generate gas. The gas enters the wine container through air pipe 230, increasing the air pressure inside the container. Under this pressure, the wine is discharged through the first outlet pipe 240, facilitating the spraying of the wine.

[0030] The wine sprinkler provided in this application is manually operated, requiring no external power source such as electricity, thus limiting its application scenarios. Furthermore, the wine sprinkler is easy to operate; the user only needs to step on the pedal 220 to sprinkle the wine, effectively reducing the user's workload while helping them maintain high work efficiency. Moreover, the user can adjust the speed and amount of wine sprinkled according to the pressure applied while stepping, meeting different usage needs and enhancing its flexibility.

[0031] In some embodiments, such as Figure 1 As shown, the air pump assembly 200 also includes a base 250, on which the air pump 210 and the pedal 220 are fixedly mounted. Optionally, the pedal 220 and the base 250 are integrally formed.

[0032] The base 250 serves as the mounting foundation for the air pump 210 and the pedal 220, providing support and fixation. The base 250 can be made of high-strength plastic or metal materials and can be designed in different shapes and sizes according to actual needs. When the air pump 210 and the pedal 220 are fixedly installed on the base 250, a secure connection can be achieved through screws, clips, or other connection methods. In some specific embodiments, the pedal 220 and the base 250 can be manufactured into a single structure through processes such as injection molding or casting. This one-piece molding design makes the pedal 220 and the base 250 an independent unit, thereby reducing production costs.

[0033] The base 250 provides a stable mounting foundation for the air pump 210 and pedal 220. Integrating the air pump 210 and pedal 220 onto the base 250 allows for a more compact structure of the air pump assembly 200, saving space. Furthermore, when the pedal 220 and base 250 are integrally molded, the number of connecting parts is reduced, lowering production and assembly costs, while also enhancing the durability of the pedal 220.

[0034] In some embodiments, such as Figure 1 As shown, the base 250 includes a base plate 251 and two side plates 252, which are fixedly installed on opposite sides of the base plate 251; the air pump 210 is located in the space enclosed by the base plate 251 and the two side plates 252.

[0035] The base plate 251 is the bottom support part of the base 250, and it can be a rectangular flat plate structure or other basically flat structure. The base plate 251 can provide the main support surface, and in actual use, the base plate 251 may or may not be in contact with the ground. Two side plates 252 are located on opposite sides of the base plate 251, and the two side plates 252 can be symmetrically arranged about the base plate 251. Optionally, the side plates 252 can be rectangular flat plate structures or block structures. The two side plates 252 can be vertical walls extending upward from both sides of the base plate 251. Together with the base plate 251, they form a U-shaped or groove-shaped protective structure, so that the space enclosed by the base plate 251 and the side plates 252 forms a semi-open protective shell. The air pump 210 is disposed in the space formed by the base plate 251 and the two side plates 252. The height of the side plates 252 can be designed according to the height of the air pump 210. The side plates 252 can be used to prevent the air pump 210 from being subjected to lateral impacts. The pedal 220 can also be located between the two side plates 252, so that the movement trajectory of the pedal 220 is restricted between the two side plates 252. The side plates 252 can guide and restrict the range of motion of the pedal 220.

[0036] Optionally, the side plate 252 and the base plate 251 can be an integral structure. Of course, the side plate 252 can also be fixedly installed to the base plate 251 by welding, screw connection or other means, without any special restrictions.

[0037] The space formed by the base plate 251 and the side plates 252 can provide good protection for the air pump 210, effectively preventing damage to the air pump 210 from external collisions, squeezing, etc. At the same time, the side plates 252 on both sides can play a certain limiting role when the user steps on the pedal 220, effectively preventing the pedal 220 from deviating due to excessive force when the user steps on it.

[0038] In some embodiments, such as Figure 1 As shown, the pedal 220 includes a first connecting section 221; the first end of the first connecting section 221 is connected to the base 250, and the second end of the first connecting section 221 extends obliquely upward.

[0039] The first connecting segment 221 can be the main body of the pedal 220, and it can be a rectangular plate structure. The end of the first connecting segment 221 closest to the base 250 is the first end of the first connecting segment 221, and the end furthest from the base 250 is the second end. The first end of the first connecting segment 221 is connected to the base plate 251. Optionally, the first connecting segment 221 and the base plate 251 are integrally formed or hinged. The second end of the first connecting segment 221 can be positioned obliquely upwards towards the air pump 210, so that the first connecting segment 221 of the pedal 220 naturally tilts upwards above the base 250, thereby forming an acute angle between the plane of the first connecting segment 221 and the upper surface of the base plate 251. This design makes the initial position of the pedal 220 more ergonomic.

[0040] The upward-sloping design of the first connecting section 221 is ergonomic, eliminating the need for excessive foot lifting during pedaling, reducing fatigue and improving comfort. Secondly, the upward-sloping structure facilitates the application of pressure, efficiently converting pedaling force into power to drive the air pump 210.

[0041] In some embodiments, such as Figure 1 As shown, the pedal 220 also includes a second connecting section 222. The first end of the second connecting section 222 is connected to the first connecting section 221. The second end of the second connecting section 222 extends obliquely upward, and the slope of the second connecting section 222 is less than the slope of the first connecting section 221.

[0042] The second connecting segment 222 can be a rectangular plate structure. It connects to the first connecting segment 221 to form a continuous pedal 220 structure. The two segments can be integrally molded or fixedly connected. The first connecting segment 221 is mainly responsible for connecting to the base 250 and bearing the main torque; its slope is relatively steep. The second connecting segment 222 connects to the end of the first connecting segment 221. Although its extension direction is also slanted upwards, its slope (i.e., the angle with the horizontal plane) is smaller and gentler, making it easier for the second connecting segment 222 of the pedal 220 to conform to the sole of the foot. Optionally, the transition between the first connecting segment 221 and the second connecting segment 222 can be a smooth curve or a distinct angle. It is understood that in this application, the terms "upper", "lower", "vertical", "horizontal", "bottom", "inner", "outer" and other indicating directions or positional relationships are only used to explain the relative positional relationships and movement of the components in a specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0043] The relatively flat design of the second connecting section 222 provides a better support surface for the foot, making it easier for the user to apply pressure stably and effectively improving the comfort of use, especially suitable for scenarios that require frequent pedaling.

[0044] In some embodiments, such as Figure 1 As shown, the first liquid outlet pipe 240 is a rigid pipe, the first liquid outlet pipe 240 is straight, and the first liquid outlet pipe 240 is perpendicular to the upper surface of the sealing cover 100.

[0045] The first outlet pipe 240 can be made of a rigid material (such as stainless steel, rigid plastic, or glass) to ensure sufficient strength and rigidity, preventing bending and deformation. The straight structure of the first outlet pipe 240 reduces resistance to liquid flow within the pipe, facilitating smoother outflow. The design of the first outlet pipe 240 being perpendicular to the upper surface of the sealing cap 100 means that the axis of the first outlet pipe 240 is perpendicular to the plane containing the upper surface of the sealing cap 100, providing a good foundation for connecting other pipes. It is understood that "perpendicular" does not require an absolute geometric relationship, but rather a basic perpendicularity that includes reasonable manufacturing tolerances and negligible deviations.

[0046] The rigidity of the tube helps maintain the structural stability of the first outlet pipe 240, preventing it from bending under the pressure of the liquid and ensuring unobstructed flow of the liquid. Secondly, the straight structure of the first outlet pipe 240 reduces resistance to the flow of the liquid, facilitating rapid flow from the container. Furthermore, the perpendicular design of the first outlet pipe 240 to the sealing cap 100 facilitates its installation and provides convenience for connecting it to other pipes.

[0047] In some embodiments, such as Figure 1 As shown, the air pump assembly 200 also includes a second liquid outlet pipe 260, which is a flexible tube. The first end of the second liquid outlet pipe 260 is connected to the first liquid outlet pipe 240, and the second end of the second liquid outlet pipe 260 is a free end. The second liquid outlet pipe 260 is flat.

[0048] The second outlet tube 260 can be a flexible tube, made of food-grade silicone or rubber, providing good flexibility and corrosion resistance for easy bending and direction adjustment. The end of the second outlet tube 260 closest to the first outlet tube 240 is the first end, and the end furthest from the first outlet tube 240 is the second end. The connection between the first end of the second outlet tube 260 and the first outlet tube 240 can be achieved using a sleeve or snap-fit ​​connection to ensure a tight, leak-proof connection. The second end of the second outlet tube 260 is a free end, allowing for easy movement as needed. The flat design of the second outlet tube 260 can refer to the tube body and the cross-section of the internal pipe being approximately slit-shaped, or it can mean that the cross-section of the internal pipe of the second outlet tube 260 is approximately slit-shaped. The slit-shaped design of the pipe facilitates a wider spray area when the liquid flows out.

[0049] The flexible hose of the second dispensing tube 260 allows it to bend and adjust its direction freely, enabling users to spray the liquid to different locations as needed, increasing flexibility and convenience. The flat design of the second dispensing tube 260 helps to change the flow pattern of the liquid, allowing it to be sprayed in a fan or sheet shape, expanding the spraying area and making it suitable for scenarios requiring large-area dispensing. Simultaneously, the slit-shaped tube also helps to increase the liquid flow rate, resulting in a longer spraying distance.

[0050] In some embodiments, such as Figure 1 As shown, the second end of the second outlet pipe 260 is provided with a detachable spray head (not shown in the figure). In some embodiments, the sealing cap 100 is also provided with a handle 110, which is arc-shaped.

[0051] The spray heads can be made of plastic or metal, and there can be multiple spray heads. Each spray head can have a different internal flow channel structure so that different spraying effects, such as mist or jet, can be created when different spray heads are used. The connection between the spray head and the second liquid outlet pipe 260 can be detachable, such as by plug-in or snap-fit ​​connection, to facilitate the removal or replacement of the spray head.

[0052] The handle 110 can be integrally formed with or fixedly connected to the sealing cap 100. The handle 110 provides a position for the user to apply force, and its arc-shaped design conforms to the gripping habits of the human hand, making it convenient for the user to operate the wine dispenser. In some specific embodiments, the sealing cap 100 is circular, the handle 110 is fixedly assembled with the sealing cap 100, and the projection of the handle 110 on the upper surface of the sealing cap 100 coincides with the diameter of the sealing cap 100.

[0053] Installing detachable spray heads facilitates functional versatility and specialization. Users can replace different spray heads according to their actual needs, effectively expanding the application scenarios of the wine sprinkler. The handle 110 provides a stable grip point for the user, and its curved design is ergonomic, effectively improving holding comfort.

[0054] In some embodiments, such as Figure 1 As shown, the air pump assembly 200 also includes a pressure gauge 270, which is connected to the air supply pipe 230 and is used to detect the air pressure in the air supply pipe 230.

[0055] The pressure gauge 270 can be an instrument for measuring air pressure, and can be either an analog or digital pressure gauge. The pressure gauge 270 is fixed to the gas supply pipe 230 and is connected to the gas supply pipe 230. The pressure gauge 270 is used to display the gas pressure value within the gas supply pipe 230 in real time, and the user can adjust the force and frequency of pedaling the pedal 220 based on the value measured by the pressure gauge 270.

[0056] Pressure gauge 270 can display the air pressure in the air supply pipe 230 in real time. Users can judge the pressure inside the wine container based on the air pressure value, and thus reasonably control the force and frequency of stepping on the pedal 220 to avoid damage to the wine container or excessive spillage due to excessive pressure. Secondly, by observing pressure gauge 270, users can understand the working status of the wine dispenser. If the air pressure is abnormal, the fault can be detected and troubleshooted in time.

[0057] In a second aspect, embodiments of this application provide a wine dispensing device, which mainly includes the aforementioned wine dispenser and a wine container (not shown in the figure). The wine container includes an opening; a sealing cap 100 matches the opening and is used to seal the opening.

[0058] A wine container is a component used to hold wine, and can be made of materials such as glass, ceramic, plastic, or metal. It has an internal space for holding the wine, the size of which can be designed according to actual needs. An opening connects the holding space to the outside; the opening is usually located at the top of the container and can be round, square, or other shapes. A sealing cap 100 is used to seal the opening. The sealing cap 100 matches the contact surface of the opening to ensure a tight seal, effectively preventing gas leakage and wine spillage.

[0059] Generally, barrels, jars, and other containers without lids can be considered as containers for the liquid, with their internal space serving as the holding space. The inner wall or edge of the opening for pouring out the liquid can then be sealed to the sealing cap 100. In some cases, the sealing connection may include screw-on, sleeve-on, or snap-on methods.

[0060] Those skilled in the art will understand that Figure 1 The structure shown is merely a schematic diagram of a portion of the structure related to the present application and does not necessarily constitute a limitation on the product form to which the technical solution of the present application is applied. Specific wine sprayers and wine spraying devices may include more or fewer parts than the structure shown in the figure, or may have a structure that is not exactly the same.

[0061] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this application.

[0062] The above embodiments merely illustrate several implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of protection of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the appended claims.
