Description

Technical Field

[0001] The utility model relates to the technical field of soap dispensers, in particular to an anti-theft and anti-tamper soap dispenser used in public places and capable of reducing the use of plastics. Background Art

[0002] With the rise of environmental awareness, the world is calling for a reduction in the use of single-use plastics, and regulations are being enacted to limit their use. The biggest impact on industries like hotels and airlines is the shift away from small bottles of toiletries and body care products. These are being replaced with wall- or tabletop-mounted soap dispensers capable of holding larger volumes of liquid.

[0003] Currently, the primary function of widespread soap dispensers is to secure large plastic bottles to walls, which can, to a certain extent, prevent users from stealing the contents. However, ensuring the liquid in the bottles remains contaminated is often difficult to achieve, as existing soap dispensers often lack the ability to lock their twist-off pump heads. Alternatively, they utilize check pumps, making it difficult for staff to refill large plastic bottles. This results in the need to replace both the bottle and pump head after use, resulting in wasteful plastic waste. Relatively few soap dispensers on the market offer both theft and tamper-proof features.

[0004] In summary, existing soap dispensers usually have problems such as poor anti-theft and anti-tampering effects, serious plastic waste, pollution caused by repeated filling, difficult maintenance, unsightly appearance and poor user experience. Utility Model Content

[0005] To this end, the present invention provides an anti-theft and anti-tamper soap dispenser for public occasions and capable of reducing the use of plastics, so as to solve the above-mentioned problems in the prior art.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solution: an anti-theft and anti-tamper soap dispenser for public places that can reduce the use of plastic, including a structure in which an inner shell and an outer shell slide together. When the inner shell and the outer shell fit together, an enclosed space is formed for accommodating and holding refillable bottles or disposable bags. The inner shell and the outer shell are fixed and locked by a spring and a metal pin. A card slot is provided on the back to enhance the connection strength, and can only be opened with a magnetic key.

[0007] Furthermore, the back of the inner shell is set to a flat surface and is provided with at least one threaded hole, allowing the inner shell to be fixed to the wall by gluing or screwing. At the same time, the locking mechanism of the inner shell and the outer shell allows the entire soap dispenser to be fixed to the wall.

[0008] Furthermore, it also includes an anti-tampering mechanism consisting of a pump head, a pump core sleeve and a magnetic key. The pump core sleeve is passed through the inside of the outer shell and is locked with the hexagonal edge in the middle of the pump core sleeve using the hexagonal wrench at the tail of the key. After the pump core sleeve is screwed to the pump head, the relationship between static friction and dynamic friction is controlled to ensure that the pump head cannot be unscrewed for tampering from the outside. Only staff can open the inner shell and outer shell and use the key to remove the pump head.

[0009] Furthermore, two liquid packaging solutions are provided: one is a refillable bottle and the other is a disposable bag.

[0010] Furthermore, the refillable bottle pumps liquid through the cooperation of the pump core sleeve and the pump head, and the bottle is provided with a sealing cover to prevent the liquid from volatilizing and being contaminated.

[0011] Furthermore, the disposable bag needs to be used in conjunction with a baffle, the bag is fixed by the buckle and slot structure of the baffle and the inner shell, and the pump core sleeve punctures the bag to enable liquid use.

[0012] Furthermore, the bottle can be repeatedly filled a fixed number of times and then cleaned, disinfected or replaced. The bag is disposable, and the pump head and pump core sleeve are detachable structures and can also be cleaned, disinfected or replaced.

[0013] Furthermore, a locking mechanism consisting of welded structural parts, springs and metal pins is provided inside the shell, which allows the use of a magnetic key to quickly unlock by compressing the spring and sucking the pin, making it easy to replace the contents. At the same time, the shell and baffle are provided with transparent or translucent observation windows to facilitate monitoring of the liquid residue.

[0014] Furthermore, all detachable parts are designed to be easy to clean and replace, and the outer shell and inner shell are made of corrosion-resistant and easy-to-clean materials.

[0015] Compared with the existing technology, it has the following beneficial effects:

[0016] 1. Significantly enhanced anti-theft performance: The sliding sleeve cooperation between the inner and outer shells, the fixed locking mechanism of the spring and metal lock pin, combined with the card slot design on the back, greatly improves the anti-theft performance of the soap dispenser, ensuring that unauthorized personnel cannot easily open and steal the liquid in the container.

[0017] 2. Effectively prevent tampering: The unique coordinated locking design of the pumping assembly, outer shell, inner shell and magnetic key makes it impossible to unscrew the pump head for tampering from the outside. Only staff can remove the pump head using the magnetic key, thus ensuring the safety and integrity of the liquid.

[0018] 3. Reduce plastic waste: Two options are available: a refillable soap bottle and a disposable soap bag. The reusable soap bottle reduces plastic consumption, while the soap bag, while disposable, uses far less plastic than traditional disposable bottles and does not need to be replaced at the same time as the pump head, further reducing plastic waste.

[0019] 4. Reduce the risk of contamination from repeated filling: The soap bottle can be refilled and needs to be cleaned, disinfected, or replaced after a fixed number of times, while the soap bag is single-use, avoiding the contamination problems caused by repeated filling. The pump head and pump cartridge are also designed to be removable and cleanable, further ensuring hygiene and safety.

[0020] 5. Easy maintenance and content replacement: The inner shell and outer shell can be unlocked quickly and easily by a magnetic key, and the observation windows on the outer shell and baffle allow staff to easily monitor the liquid level and replace it in time, greatly simplifying the maintenance process.

[0021] 6. Enhanced User Experience: The innovative connection method eliminates traditional external restrictions, simplifies the appearance, reduces user defensiveness, and improves the overall user experience. At the same time, the stable installation design and convenient operation method also enhance user satisfaction.

[0022] In summary, through a number of technological innovations and design optimizations, significant improvements have been achieved in ensuring safety, reducing waste, lowering pollution, and facilitating maintenance, which is of great significance for improving the efficiency of cleaning products in public places and user experience.

[0044] like Figure 7 As shown, the magnetic key 6 includes a handle 61, a reserved groove 2 62 is provided at one end of the handle 61, and a hexagonal wrench 63 is connected to the other end. The hexagonal wrench 63 is adapted to the nut 31, and a magnet 64 is fixed inside the reserved groove 2 62.

[0045] like Figures 8 and 9 As shown, a locking protrusion 71 that is compatible with the limiting protrusion 11 is provided on the back of the baffle 7, and a bag cavity 72 that can accommodate the soap liquid bag 9 is reserved inside the baffle 7. The bottom of the locking protrusion 71 is connected to the baffle buckle 73. The baffle buckle 73 can be deformed after being squeezed and can recover otherwise. A second card slot 74 is reserved on both sides of the bottom of the baffle 7.

[0046] This embodiment solves the problems of poor anti-theft and anti-tampering effects, serious plastic waste, pollution caused by repeated filling, difficult maintenance, unsightly appearance and poor user experience in the following technical solutions:

[0047] 1. In the technical solution to the problem of theft prevention, the inner shell 1 and the outer shell 2 are fitted together by means of a sliding sleeve, and after the inner shell 1 and the outer shell 2 are fitted together, a space can be formed inside the shell to accommodate a soap bottle 8 or a soap bag 9 to hold daily chemical liquids, and a spring 55 and a metal lock pin 54 are used between the inner shell 1 and the outer shell 2 to fix and lock the inner shell 1 and the outer shell 2, and there are corresponding card slots on the back to further enhance the connection strength between the inner shell and the outer shell, so that ordinary users cannot open the inner shell 1 and the outer shell 2 by themselves to steal the container containing liquid. The staff can use a magnetic key 6 to open the inner shell and the outer shell. The limiting protrusion 11 on the back of the inner shell 1 is a flat surface and is attached with a plurality of threaded holes 16. The inner shell 1 can be fixed to the wall by gluing or screwing, and the inner shell and the outer shell can be locked to each other so that the entire product can be fixed to the wall;

[0048] 2. In the technical solution to the problem of poor anti-tampering effect, the inner shell 1 and the outer shell 2 can be locked to each other and mounted on the wall to prevent theft. At the same time, a reserved hole 24 is set at the upper end of the outer shell 2 to cooperate with the pump core sleeve 3 and the pump head 4. Through the outer shell 2, the pump core sleeve 3, the pump head 4, the magnetic key 6 and other components: the pump core sleeve 3 is inserted upward from the inside of the outer shell 2 at the reserved hole 24, so that the part of the threaded groove 33 of the upper section of the pump core sleeve 3 is exposed to the outside of the outer shell 2, and the hexagonal wrench 63 at the tail of the magnetic key 6 is engaged with the hexagonal nut 31 in the middle section of the pump core sleeve 3, and the magnetic key 6 is rotated. The pump core sleeve 3 is driven to rotate by the hexagonal wrench 63 and the hexagonal nut 31 to assemble. After the pump core sleeve 3 is assembled, the internal structures of the outer shell 2 are locked to each other, and then the fixed pump core sleeve 3 is screwed to the pump head 4. After screwing, the screw thread of the pump head 4 is aligned with the screw thread of the pump head 4. The screw groove 33 of the pump core sleeve 3 is connected, the lower surface of the pump head 4 contacts the upper surface of the outer shell 2, and the upper surface of the limit retaining ring 32 in the middle section of the pump core sleeve 3 contacts the lower surface of the inner shell 2. Moreover, by controlling the friction force, after assembly and screw connection, the static friction range between the screw thread of the pump head 4 and the screw groove 33 is greater than the sum of the dynamic friction between the pump head 4 and the outer shell 2 and the dynamic friction between the pump core sleeve 3 and the outer shell 2 when the pump head 4 is rotated externally, thereby achieving the function of preventing the pump head 4 from being unscrewed from the outside to tamper with the liquid, and the staff can use the hexagonal wrench 63 of the magnetic key 6 to disassemble the pump head 4 and the pump core sleeve 3 after opening the inner shell 1 and the outer shell 2;

[0049] Third, in a technical solution to the serious problem of plastic waste, the inner shell 1 and outer shell 2 mate to form a space inside for a soap bottle 8 or a soap bag 9 for holding liquid. This embodiment provides two liquid holding solutions: the soap bottle 8 and the soap bag 9. The soap bottle 8 pumps liquid from the bottle interior through the cooperation of the pump core sleeve 3 and the pump head 4, allowing for repeated filling, reducing the use of disposable plastics and reducing plastic waste. Furthermore, the soap bag 9 must be used in conjunction with the baffle 7 when in use. The baffle 7 is provided with a baffle buckle 73 and a second card slot 74, which can be matched and snapped with the first card slot 17 and the card plate 18 at the bottom of the inner shell 1 to form a semi-enclosed space. The soap liquid bag 9 can be placed through the gap, and the bag is fixed by the inner shell 2 and the baffle 7. The sharp portion 34 at the bottom of the pump core sleeve 3 can puncture the fixed soap liquid bag 9 during the process of fitting the inner shell 1 and the outer shell 2, so that the soap liquid bag 9 can be used to hold liquid. The soap liquid bag 9 is disposable, but compared with disposable bottles, the amount of plastic used in the soap liquid bag 9 is greatly reduced, and there is no need to match the pump head for simultaneous replacement;

[0050] Fourth, in the technical solution to solve the problem of contamination caused by repeated filling, the two liquid holding methods of the soap liquid bottle 8 and the soap liquid bag 9 are provided. The soap liquid bottle 8 can be repeatedly filled a fixed number of times and then cleaned, disinfected or replaced. The soap liquid bag 9 is disposable and does not cause repeated filling contamination. The pump head 4 and the pump core sleeve 3 are detachable structures and can be cleaned, disinfected or replaced after a fixed number of uses.

[0051] 5. In the technical solution to the maintenance difficulty problem, a spring 55 and a metal lock pin 54 are used between the inner shell 1 and the outer shell 2 to fix and lock the inner shell 1 and the outer shell 2. There is a welded structural part at the upper end of the inner shell 2, which can form a space with the outer shell 2 to accommodate the metal lock pin 54 and the corresponding spring 55. The lock pin 54 can pass through the reserved hole of the welded part, and the head of the lock pin 54 can be protruded from the reserved hole and fit into the lock pin hole 15 at the upper end of the inner shell 1 to achieve a snap-on effect. The staff can use the magnet 64 at the front of the magnetic key 6 to absorb the lock pin 54, compress the spring 55, and separate the lock pin 54 from the lock pin hole 15, thereby completing the unlocking action. Unlocking is convenient and simple, and the contents can be quickly replaced after unlocking. At the same time, observation windows are reserved on the outer shell 2 and the baffle 7. The staff can easily observe the remaining liquid content through the observation window and replace it at the appropriate time.

[0052] 6. In the technical solution to solve the problems of unsightly appearance and poor user experience, an innovative connection method is used to eliminate the external restriction mechanism used in the traditional soap dispenser locking pump, thus avoiding the cumbersome appearance. At the same time, due to the elimination of the external restriction mechanism, the defensive information transmission to users can be reduced, thereby improving the user experience.

[0053] Although the present invention has been described in detail above using general descriptions and specific embodiments, it will be apparent to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, such modifications or improvements, without departing from the spirit of the present invention, are within the scope of protection claimed herein.

[0054] The terms "upper", "lower", "left", "right", "middle", etc. used in this specification are only for the convenience of description and are not intended to limit the scope of implementation of the present invention. Changes or adjustments to their relative relationships should be considered as the scope of implementation of the present invention without substantially changing the technical content.
