Technical Field

[0001] The invention relates to the field of special parts for smart tissue boxes, and in particular to a waterproof structure suitable for smart tissue boxes. Background Art

[0002] Toilet paper roll boxes are widely used and can be found in bathrooms in homes, hotels, shopping malls, etc. They are one of the indispensable supplies in modern human life. However, at present, contaminated paper towels often appear in the toilet paper roll boxes of some public toilets, which can easily cause cross infection to people and affect their health.

[0003] The smart tissue box is a brand-new niche product, mainly used in the home field and small offices with a small number of people. Through chip control, it can provide tissues of different standard lengths according to different needs, eliminating waste and all kinds of dirt caused by exposed tissues. At the same time, since the paper is automatically discharged, there is no problem of paper breaking, and there will be no embarrassment caused by tissues breaking in the tissue box. Finally, since the smart tissue box comes with a paper cutter, it can cut the paper according to the actual paper output situation. After the user takes the paper, the remaining paper is still in the tissue box. In the next use, there is no need to discard a small piece of tissue due to exposed and dirty tissues. Due to the built-in electronic equipment, the waterproof requirement of the smart tissue box ranks first among all requirements.

[0004] The current smart tissue boxes, whether or not they have built-in electronic devices, have a contradiction: the flip cover design is convenient to use but not waterproof, and the top cover design is waterproof but inconvenient to use. Therefore, it is necessary to design a waterproof structure suitable for smart tissue boxes. Summary of the invention

[0005] In order to overcome the defects in the prior art, a waterproof structure suitable for a smart tissue box is provided.

[0006] The present invention is achieved through the following scheme:

[0007] A waterproof structure suitable for an intelligent tissue box, comprising a tissue box flip cover and a tissue box base that match each other, the waterproof structure also comprising a waterproof adhesive strip and a waterproof slope that matches the tissue box flip cover, the waterproof adhesive strip being correspondingly connected to the waterproof adhesive strip, the waterproof slope being correspondingly arranged on the side of the open portion of the tissue box base, the waterproof adhesive strip comprising a fixed portion and a cross portion, the fixed portion and the cross portion being correspondingly connected via a bent portion, and the cross portion being capable of correspondingly contacting the waterproof slope.

[0008] The lower part of the tissue box base is hinged to the lower part of the tissue box flip cover, and the upper part of the tissue box flip cover is detachably connected to the upper part of the tissue box base.

[0009] A plurality of pin holes are correspondingly arranged on the lower side of the open portion of the tissue box base, and a plurality of pin shafts are correspondingly arranged on the lower portion of the tissue box flip cover. The pin shafts are correspondingly inserted into the pin holes and can rotate in the pin holes.

[0010] A concave lock hole is correspondingly arranged on the upper side of the opening of the tissue box base, and a protruding lock tongue is correspondingly arranged on the upper part of the flip cover of the tissue box, and the lock tongue can be correspondingly inserted into the lock hole.

[0011] The waterproof slope is divided into three sections, which are respectively arranged at the upper end, the left end and the right end of the open end of the tissue box base, and the three sections of the waterproof slope are integrally formed, and the angle between the waterproof slope and the horizontal plane is 15-75 degrees;

[0012] The waterproof adhesive strip is divided into three sections and is respectively arranged at the upper end, the left end and the right end of the tissue box flip cover close to the tissue box base, and the three sections of the waterproof adhesive strip are integrally formed.

[0013] The end of the intersection portion is a smooth curved surface, and the curved portion is curved toward the waterproof slope.

[0014] The thickness of the waterproof rubber strip is 1.0-1.5 mm, the hardness of the waterproof rubber strip is Shore A25°-50°, and the length of the intersection is 3-5 mm.

[0015] The beneficial effects of the present invention are:

[0016] The waterproof structure of the smart tissue box is suitable for waterproofing a tissue box with a flip cover design. The edge of the tissue box base is not a traditional step design, but a slope design. After assembly, the waterproof adhesive strip slides down along the slope of the tissue box base and adheres to the slope through its own deformation ability to achieve a waterproof effect. The structure is ingenious, the waterproof effect is good, and the cost is low. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The preferred embodiments of the present invention are further described below in conjunction with the accompanying drawings:

[0023] A waterproof structure suitable for a smart tissue box, comprising a tissue box flap 3 and a tissue box base 4 that match each other, the waterproof structure also comprising a waterproof adhesive strip 1 and a waterproof slope 2 that matches the tissue box flap 3, the waterproof adhesive strip 2 being correspondingly connected to the waterproof adhesive strip 1, the waterproof slope 2 being correspondingly arranged on the side of the open portion of the tissue box base 4, the waterproof adhesive strip 1 comprising a fixing portion 11 and a crossing portion 12, the fixing portion 11 and the crossing portion 12 being correspondingly connected via a bending portion 13, and the crossing portion 12 being able to contact and deform correspondingly with the waterproof slope 2.

[0024] The lower part of the tissue box base 4 is hinged to the lower part of the tissue box flip cover 3 , and the upper part of the tissue box flip cover 3 is detachably connected to the upper part of the tissue box base 4 .

[0025] A plurality of pin holes 41 are correspondingly provided on the lower side of the open portion of the tissue box base 4, and a plurality of pin shafts 31 are correspondingly provided on the lower portion of the tissue box flip cover 3. The pin shafts 31 are correspondingly inserted into the pin holes 41, and the pin shafts 31 can rotate in the pin holes 41, so that the tissue box base and the tissue box flip cover form a door-like structure, which can be opened and closed separately.

[0026] A concave lock hole 42 is correspondingly provided on the upper side of the open portion of the tissue box base 4, and a protruding lock tongue 32 is correspondingly provided on the upper portion of the tissue box flip cover 3. The lock tongue 32 can be correspondingly inserted into the lock hole 42. The lock hole and the lock tongue form a self-locking switch to complete the opening and closing of the tissue box flip cover. When the lock tongue is inserted into the lock hole, the tissue box flip cover and the tissue box base are closed. At this time, the waterproof rubber strip contacts and rebounds with the waterproof slope to prevent water from entering, thereby achieving a sealing effect.

[0027] The waterproof slope 2 is divided into three sections and is respectively arranged at the upper end, left end and right end of the open portion of the tissue box base 4, and the three sections of the waterproof slope 2 are integrally formed, and the angle between the waterproof slope 2 and the horizontal plane is 15-75 degrees; the waterproof adhesive strip 1 is divided into three sections and is respectively arranged at the upper end, left end and right end of the side of the tissue box flip cover 3 close to the tissue box base 4, and the three sections of the waterproof adhesive strip 1 are integrally formed. The three-section waterproof slope and waterproof adhesive strip are matched and sealed with each other to achieve the best waterproof effect.

[0028] The end of the intersection 12 is a smooth curved surface, and the curved portion 13 is curved toward the waterproof slope 2. The curved intersection 12 is in corresponding contact with the waterproof slope 2 to achieve a better waterproof effect.

[0029] The thickness of the waterproof rubber strip 1 is 1.0-1.5 mm, the hardness of the waterproof rubber strip 1 is 25°-50° Shore A, and the length of the cross section 12 is 3-5 mm. The thickness, length and other parameters of the product of the present application can be adjusted accordingly according to the size change and waterproof requirements of the smart tissue box to meet the needs of different products and customers.

[0030] The lock tongue can be locked or opened corresponding to the lock hole. When opening, the lock tongue withdraws from the lock hole, the side of the tissue box flip cover close to the lock tongue is away from the tissue box base, and the pin shaft rotates in the pin hole; when locking, the lock tongue is correspondingly inserted into the lock hole, at this time, the tissue box flip cover moves toward the tissue box base, and the pin shaft rotates in the pin hole, so that the tissue box flip cover and the tissue box base are locked and opened. When the lock tongue is locked with the lock hole, the tissue box flip cover and the tissue box base are tightly fitted together, and at this time, the waterproof rubber strip is also in contact with the waterproof slope, wherein the contact between the waterproof rubber strip and the waterproof slope will be slightly deformed, thereby forming a waterproof sealing structure.

[0031] In the present application, the smart tissue box uses a self-locking switch consisting of a lock tongue and a lock hole. Press once to lock it, and press again to open it automatically. The lock tongue and the lock hole can be purchased from the market or made by yourself according to factors such as the product positioning of the tissue box and customer needs. The specific structure, size, principle, working process and connection method of the lock tongue and the lock hole are well-known technologies and will not be repeated here.

[0032] At present, the self-locking switch of our company's products needs to continue to move inward about 1.5mm during the opening and closing process. If our company follows the current waterproof design ideas, it must ensure 15% deformation, and then ensure that on the basis of 15% deformation, it continues to deform 1.5mm, and the resistance is less than 25N.

[0033] The core of existing rubber strips for mass consumer products is that the rubber strips are fixed on the intersecting upper cover or lower cover, and the pressure applied by the other side deforms by about 15%. It is generally divided into three parts: the protruding part of the upper cover pressing the rubber strip, the waterproof rubber strip groove on the base, and the waterproof rubber strip. When the product is assembled, the upper cover part squeezes the waterproof rubber strip. The design generally ensures that the deformation of the rubber strip is about 15%, and the maximum does not exceed 30%. According to different product designs, the hardness of the rubber strip is concentrated between 40-60 degrees (Shore A). Some of the designs are square rubber strips, but the principle is the same.

[0034] Because the volume of the smart tissue box of this application is limited, it is impossible to manufacture a waterproof structure that meets the requirements according to the traditional waterproof design. At the same time, the perimeter of the entire smart tissue box is 660mm. If the product is designed according to this length and diameter, the cost of the adhesive strip is at least more than 20 yuan, and the product volume is too large and the appearance is ugly. The life of the waterproof structure of this product is at least 3 years, which is in line with the warranty period of the smart tissue box product, which is generally 1 year.

[0035] The specific shape and curved surface composed of the fixed part, the cross part, and the curved part of the present application cooperate with the oblique angle of the slope to ensure that when the tissue box cover and the tissue box base are closed, the waterproof adhesive strip slides down along the slope of the tissue box base. Due to the elasticity of the colloid itself, a force of 0.5-1.5N / cm can be ensured to ensure that water does not penetrate into the tissue box base. The overall appearance of the waterproof structure of the present application is beautiful and the process is controllable. Due to the adoption of this design idea, the overall cost of the waterproof structure can be reduced from more than 20 yuan to less than 10 yuan.

[0036] The waterproof structure of the present application can prevent 360° water spray from the shower head. After testing, the overall waterproof effect of the waterproof structure of the present application can at least reach the IPX6 waterproof standard. Since the bottom of the tissue box base is the paper outlet, the present application does not design a waterproof structure. In actual application, the present application can also add a corresponding waterproof structure at the bottom of the tissue box base according to product requirements, which will not be repeated here.

[0037] The waterproof rubber strip of the product of the present application has taken a different approach. The waterproof rubber strip is not fixed when squeezed, but moves with the moving parts, and waterproofing is achieved through the resilience of the bending rather than the deformation of the rubber strip itself.

[0038] Although the technical solutions of the present invention have been described and listed in detail, it should be understood that it is obvious to those skilled in the art to make modifications to the above embodiments or adopt equivalent alternatives. These modifications or improvements made without departing from the spirit of the present invention are within the scope of protection required by the present invention.
