Description

Technical Field

[0001] The invention relates to the technical field of drinking water filling, and in particular to a drinking water filling overflow prevention device. Background Art

[0002] With the rapid development of the drinking water industry, the demand for drinking water filling has increased significantly. In the traditional drinking water filling process, overflow often occurs during the filling process due to improper operation or unreasonable equipment structure design, resulting in water resource waste and reduced production efficiency. Especially in high-efficiency production lines, the increase in filling speed further exacerbates the risk of overflow, affects the service life of the equipment, and increases the workload of cleaning and maintenance.

[0003] Most of the existing filling equipment relies on fixed mechanical design. Although some equipment is equipped with simple overflow prevention devices, these overflow prevention devices can only passively deal with overflow situations. There is a lack of effective overflow prevention mechanism. It is impossible to automatically adjust the filling flow according to the size and shape of different filling containers, resulting in overflow from time to time. Common overflow prevention measures currently include: flow regulation: controlling the inflow speed of the liquid by adjusting the opening of the filling valve; when the container is close to full, gradually slowing down the flow rate to prevent overflow; although this method is effective, it will cause speed fluctuations during the filling process, which will affect the overall production efficiency and capacity under efficient filling conditions; or through liquid level detection: using a liquid level sensor to detect the liquid level in the container and adjust the filling flow through the control system; when the liquid level approaches the set value, automatically reduce the flow rate; although this method can prevent overflow to a certain extent, the response speed and accuracy of the sensor may be insufficient during high-speed filling, and there is still a risk of overflow; it also needs to control the filling speed; it cannot meet the high-speed filling effect and filling continuity when filling drinking water, and there will be technical problems that greatly reduce the filling efficiency.

[0011] Preferably, the interception module also includes a driving element capable of driving the interception head radially close to or away from the reflux module and a first return spring for quickly returning the interception head in a non-driven state; when the filling tube moves longitudinally downward and close to the bottle mouth of the filling bottle, the interception head will be driven by the first return spring to be radially away from the reflux module; when the filling tube moves longitudinally upward and away from the bottle mouth of the filling bottle, the interception head contacts the driving element and drives the retention head radially close to the reflux module, thereby achieving interception.

[0036] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0037] See also Figures 1 to 10 As shown: a drinking water filling overflow prevention device, comprising a filling tube 1, a reflux module 2 coaxially arranged outside the filling tube 1 and arranged near the bottom of the filling tube 1; the liquid inlet of the reflux module 2 and the liquid outlet of the filling tube 1 are arranged flush; the storage module 3 is coaxially fixedly arranged outside the filling tube 1 and arranged near the top of the filling tube 1; the storage module 3 is connected with the liquid outlet of the reflux module 2; the interception module 4 is radially arranged on one side of the storage module 3 through a connecting frame 41 and the interception end is radially arranged toward the reflux module 2; the interception module 4 is provided with an interception head 42 which can intercept the reflux module 2 in a non-filling state and discharge the reflux module 2 in a non-filling state; the filling tube 1 is also coaxially provided with a plug 15 which can control the opening and closing of the liquid outlet of the filling tube 1 by water pressure.

[0038] When filling drinking water, first connect the access end of the filling tube 1 to the external water supply equipment to access the water source; at this time, the filling tube 1 is driven by the external vertical driver to move in the vertical direction, driving the output end of the filling tube 1 to be inserted into the bottle mouth of the filling bottle 5 for filling; since the filling mouth of the filling tube 1 is tightly matched with the bottle mouth, when entering the high-speed filling state, the drinking water will quickly fill the filling bottle 5; since the amount of drinking water exported each time is slightly larger than the volume of the filling bottle 5, when the filling bottle 5 is full, the excess water source will flow into the storage tank along the reflux module 2 Module 3; temporarily store drinking water through the storage module 3; because the interception module 4 is also provided with an interception head 42, and the interception head 42 can intercept the return module 2 in the non-filling state, and the interception head 42 can discharge the return module 2 in the non-filling state; when the filling tube 1 is driven by the vertical drive away from the filling bottle 5, the transmission path of the return module 2 will be closed; in this state, the overflowed water will be temporarily stored in the storage module 3; when the filling tube 1 is docked with the next bottle 5 to be filled, the transmission path of the return module 2 The bottle 5 to be filled is reopened and uses its own gravity to re-introduce the temporarily stored water into the new bottle 5 to be filled; this process achieves the effect of efficient filling and overflow prevention, greatly improves the filling efficiency, and solves the technical problem of water overflow during the filling process; the present invention optimizes the coordinated work of the filling pipe 1, the reflux module 2 and the storage module 3 to ensure that water overflow is effectively prevented during the high-speed filling process; through the precise control of the interception module 4 and the temporary storage function of the storage module 3, not only the filling efficiency is improved, but also the problem of water overflow during the filling of the drinking water is completely solved. The technical problem of overflow of drinking water caused by the filling can be solved, and the stability of the overall filling process and the convenience of operation are improved; further, by introducing a water source slightly larger than the volume of the filling bottle 5 into the filling bottle 5 during filling, the technical problem that a large number of bubbles will be generated in drinking water under the efficient filling state can be effectively solved, and the efficient filling pressure is used to squeeze the excess bubbles and water source into the storage module 3, so that it can be temporarily stored and reacted in the storage module 3; thereby ensuring that the drinking water in the filling bottle 5 can be filled in the filling bottle 5 in an efficient and bubble-free state.

[0039] See also Fig. 9 As shown: the filling pipe 1 is composed of a transmission pipe section 11 and a lead-out pipe section 12 which are connected in sequence; and the lead-out pipe section 12 is arranged in a conical shape.

[0040] The transmission pipe section 11 and the outlet pipe section 12 are both hollow pipes with openings at both ends; the transmission pipe section 11 is arranged in a cylindrical tube shape; the outlet pipe section 12 is arranged in a conical tube shape;

[0041] The filling tube 1 is composed of a transmission tube section 11 and an outlet tube section 12 which are connected in sequence, wherein the transmission tube section 11 is mainly responsible for transmitting the liquid from the liquid storage container to the outlet tube section 12; and since the outlet tube section 12 is arranged in a conical shape, its transmission channel is gradually arranged from wide to narrow, which is convenient for controlling the flow rate and flow of the liquid to ensure that the liquid can flow out smoothly during the filling process and reduce splashing and bubble generation; at the same time, by adopting the outlet tube section 12 arranged in a conical shape, and also utilizing its wide to narrow characteristics, the outlet tube section 12 can adjust the insertion depth when inserted into the filling bottle 5, so as to achieve the purpose of adaptively adapting to different filling bottles 5 and bottle mouth diameters; thereby meeting the effect of filling filling bottles 5 of different models.

[0042] See also Fig.10 As shown: the outlet pipe section 12 is also sleeved with a first rubber ring 13 .

[0043] The outer sleeve of the outlet tube section 12 is provided with a first rubber ring 13, which is tightly wrapped on the outer wall of the outlet tube section 12; the purpose of providing the first rubber ring 13 is to ensure that when the filling tube 1 is inserted into the bottle mouth during the filling process, the contact part between the outlet tube section 12 and the bottle mouth forms an effective seal to prevent liquid from overflowing or leaking from the bottle mouth during the filling process; the flexible material of the first rubber ring 13 can enhance the fit between the filling tube 1 and the bottle mouth, while reducing the problem of loose sealing caused by uneven contact surface or uneven force; effectively improve the stability and accuracy of the filling process, and reduce the risk of liquid waste and contamination caused by poor sealing.

[0044] See also Fig.10 As shown, a second rubber ring 14 is horizontally fixedly arranged outside the first rubber ring 13 and can be in horizontal contact with the bottle mouth of the filling bottle 5.

[0045] The second rubber ring 14 is provided to further enhance the sealing effect of the bottle mouth during the filling process; when the filling tube 1 is inserted into the bottle mouth, the first rubber ring 13 realizes a preliminary seal with the bottle mouth, and the second rubber ring 14 provides an additional sealing layer by horizontally contacting the bottle mouth, thereby preventing the liquid from overflowing or leaking from the side of the bottle mouth during the filling process; the second rubber ring 14 provided outside the first rubber ring 13 is in horizontal contact with the bottle mouth, which can further enhance the sealing performance of the bottle mouth during the filling process, ensure that the liquid does not leak, thereby improving the safety and efficiency of the filling, and reducing the waste of the filling liquid and the possibility of environmental pollution; by adopting the filling tube 1 with a conical liquid outlet, combined with the first rubber ring 1 coaxially provided on the outside of the filling tube 1 3 and the second rubber ring 14 realize how to present an efficient sealing effect during the filling process; the conical design of the filling tube 1 not only enables it to adapt to bottle mouths of different calibers, but also ensures that the filling tube 1 fits tightly with the bottle mouth, avoiding leakage problems caused by caliber differences; at the same time, the first rubber ring 13 and the second rubber ring 14 further enhance the sealing effect, ensuring that water will not overflow during the filling process even under high-speed filling conditions; under the interaction between the filling tube 1 and the first rubber ring 13, the entire filling process is smoother, avoiding the problems of low filling efficiency and water waste caused by unsealed contact surfaces or mismatched bottle mouth sizes in traditional filling systems, greatly improving the filling efficiency and adaptability of the equipment.

[0046] See also Figure 4 and Figure 8 As shown: the reflux module 2 includes a first transmission unit 21 and a second transmission unit 22; the first transmission unit 21 and the second transmission unit 22 are relatively embedded and installed on both sides of the filling tube 1 through a seal 23; the second transmission unit 22 has the same structure as the first transmission unit 21; the first transmission unit 21 is composed of a first transmission tube 221, a second transmission tube 222 and a third transmission tube 223 arranged in series; wherein the diameter of the second transmission tube 222 is smaller than that of the first transmission tube 221 and the third transmission tube 223; the liquid inlet end of the first transmission tube 221 is arranged flush with the liquid outlet end of the filling tube 1 for introducing overflow water; the liquid outlet end of the third transmission tube 223 is connected to the storage module 3 for introducing water into the storage module 3.

[0047] By adopting a design in which the second transmission tube 222 is smaller than the first transmission tube 221 and the second transmission tube 222, the transmission space inside the second transmission tube 222 is reduced to a certain extent. At this time, when the filling tube 1 is driven away from the filling bottle 5 by the vertical drive, the intercepting end of the intercepting module 4 can achieve the effect of intercepting the transmission path in the second transmission tube 222 by applying a small pressure and a limiting stroke to the second transmission tube 222, thereby limiting the autonomous flow of drinking water.

[0048] See also Figure 2As shown: the storage module 3 is a storage bin; the storage bin is a hollow storage ring arranged in an annular shape, used to store the water source introduced through the fallback module.

[0049] The storage chamber is used to store the liquid introduced through the reflux module 2, ensuring that the overflowed or excess liquid can be recovered in time during the filling process; since the storage module 3 is arranged in an annular shape, its structural design helps to optimize the space utilization, can evenly distribute the liquid, and avoid the risk of local accumulation or overflow; further improve the reflux and storage efficiency of the system; through the cooperation of the reflux module 2 and the storage module 3, the technical problem of overflow of drinking water due to excessive filling is effectively solved; the reflux module 2 can quickly capture the overflowed liquid, and through its connection design with the storage module, the overflowed liquid is quickly introduced into the storage module, thereby realizing the efficient recovery of the overflowed liquid; this not only reduces the waste of drinking water caused by excessive overflow during the filling process, but also avoids the pollution problem of the bottle body caused by the overflow of liquid; and the traditional filling device usually needs to slow down the filling speed to prevent overflow when the bottle mouth is filled, which not only reduces the production efficiency, but also increases the complexity of operation; and the present invention realizes the function of automatically recovering the overflowed liquid under high-speed filling state by designing the conical filling tube 1 and the reflux module 2, avoiding the pollution and waste caused by the overflow of liquid, without the need for additional deceleration operation, and greatly improving the filling efficiency.

[0050] See also Figure 1 , Figure 8 and Fig.10 As shown: the interception module 4 also includes a driving element 43 capable of driving the interception head 42 to radially approach or move away from the reflux module 2 and a first return spring 424 for quickly returning the interception head 42 in a non-driven state; when the filling tube 1 moves longitudinally downward and approaches the bottle mouth of the filling bottle 5, the interception head 42 will be driven by the first return spring 424 to be radially away from the reflux module 2; when the filling tube 1 moves longitudinally upward and away from the bottle mouth of the filling bottle 5, the interception head 42 contacts the driving element 43 and drives the retention head 42 to radially approach the reflux module 2, thereby achieving interception.

[0051] The first return spring 424 is coaxially sleeved and installed outside the shutoff head 42, and one end of the first return spring 424 abuts against the shutoff head 42, and the other end abuts against the connecting frame 41;

[0052] When the filling tube 1 moves down longitudinally and approaches the mouth of the filling bottle 5, the driving element 43 is activated to push the intercepting head 42 radially away from the reflux module 2, so that the reflux module 2 is in an open state, allowing the refluxed water source to flow out; on the contrary, when the filling tube 1 moves up and away from the mouth of the filling bottle 5, the driving element 43 is activated to push the intercepting head 42 radially close to the reflux module 2, close it, and prevent the water source from overflowing; through this design, the system can realize automatic control during the filling process, avoiding the need for manual adjustment, and can effectively prevent the water source from leaking out when the filling tube 1 is moved away; in addition, the design can greatly increase the filling speed while preventing overflow by dynamically controlling the opening and closing of the intercepting module 4, especially in the case of high-speed filling, which has a significant effect on improving the production efficiency of the equipment.

[0053] See also Figure 4 and Fig.10 As shown: the interception head 42 is composed of a guide part 421, a sliding part 422 and a interception part which are connected in series in sequence; the sliding part 422 is slidably matched with the connecting frame 41; the guide part 421 is set in contact with the driving end of the driving element 43; the interception part 423 is set in contact with the outer wall of the reflux module 2 to achieve interception of the reflux module 2.

[0054] In the working state, when the filling tube 1 moves downward longitudinally under the drive of the vertical driver, the guide portion 421 in conflict with the driving element 43 will be radially away from the reflux module 2 under the support of the first return spring 424, and the sliding portion 422 will slide under the guidance of the connecting frame 41, thereby pulling away from the intercepting portion 423 in conflict with the reflux module 2, so as to achieve the discharge effect. Accordingly, when the filling tube 1 moves upward longitudinally under the drive of the vertical driver, the guide portion 421 will contact the driving element 43 again, thereby compressing the first return spring 424, and driving the intercepting portion 423 to be radially pressed to the outside of the reflux module 2 again through the sliding portion 422, thereby achieving the discharge effect. The interception effect is achieved; the present invention realizes how to automatically control the opening and closing of the reflux pipeline during the switching process of the filling bottle through the interception module 4; the interception module 4 can automatically switch states during the filling process to ensure that when the filling tube 1 is separated from the filling bottle 4, the reflux pipeline is closed in time to avoid overflow, and when the new filling bottle 5 is docked, the reflux pipeline will automatically open to restore the liquid recovery function; through the automatic opening and closing control mechanism, the continuity and automatic operation of the filling process are guaranteed, the misoperation or time delay that may be caused by traditional manual control is eliminated, the filling efficiency is further improved, and the stability and efficiency of the filling process are ensured.

[0055] See also Fig.10 As shown, the driving element 43 is composed of a fixing plate 431 and an adjusting plate 432 which can be longitudinally adjusted and is arranged under the fixing plate 431; a driving part 433 which is arranged obliquely is arranged at the bottom of the adjusting plate 432.

[0056] The driving part 433 fixedly arranged at the bottom of the adjusting plate 432 is an inclined plate arranged in a radial direction and inclined toward the outside of the filling tube 1, and the angle between the inclined plate and the adjusting plate 432 is greater than forty degrees and less than ninety degrees; since the adjusting plate 432 can be longitudinally adjusted along the vertical direction of the fixed plate 431, when filling barrels of different diameters need to be filled, the staff only needs to adjust the adjusting plate 432 to the required height and then adjust the driving part 433 to the required triggering height; the triggering stroke of the shut-off head 42 can be freely adjusted according to different filling requirements.

[0057] See also Fig.10 As shown: a plug 15 capable of controlling the opening and closing of the liquid outlet of the filling tube 1 is coaxially arranged inside the filling tube 1, and the plug 15 is slidably matched with the filling tube 1 through a guide rod 16 vertically arranged at the bottom; a second return spring 17 is coaxially sleeved and installed outside the guide rod 16; one end of the second return spring 17 abuts against the lower surface of the plug 15, and the other end abuts against the filling tube 1.

[0058] When the water source is filled by an external pressure-boosting device, under the initial pressure state, the plug 15 is arranged away from the liquid outlet of the filling tube 1 under the support of the second return spring 17; and when the drinking water is discharged under high pressure, the pressure used to discharge the drinking water will be greater than the elastic force setting of the second return spring 17, and the plug 15 will be axially pushed to the liquid outlet of the filling tube 1 under the pressure of the water pressure, thereby realizing the closure of the drinking water under high pressure discharge state, which is compared with the prior art that realizes the filling head and tail by reducing the conduction rate of the drinking water; further, the guide rod 16 is externally threaded with an adjusting nut; the triggering stroke of the plug can be changed by adjusting the adjusting nut.

[0059] The present invention can not only efficiently fill drinking water with different calibers, but also prevent the drinking water from overflowing during the filling process, and has high filling efficiency and good effect.

[0060] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
