[0045] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0046] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0047] Unless otherwise specifically stated, the relative arrangement, numerical expressions and numerical values ​​of the parts and steps set forth in these embodiments do not limit the scope of the present application. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be considered as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0048] In the related art, the cat litter box is sealed by a packing mechanism, but the existing packing mechanism has a poor sealing effect when packing the packing bag. Therefore, the inventor of the present application has designed a new type of hot melt component, which can solve the problem of poor sealing effect of the packing mechanism. The hot melt component of the present application will be described in detail below with reference to the accompanying drawings.

[0049] It should be noted that the “first direction” in this application refers to the Figure 1 The direction indicated by the letter X.

[0050] See also Figures 1 to 7 As shown, the present application provides a hot melt assembly 80 , which is at least used for hot melt sealing of packaging bags. The hot melt assembly 80 includes a base 10 and a heating element 20 .

[0051] Specifically, the heating element 20 is disposed on the base 10 and extends along the first direction, and the cross section of the heating element 20 is a broken line shape; wherein the cross section of the heating element 20 is a cross section obtained by cutting the heating element 20 along a direction perpendicular to the first direction.

[0052] In this embodiment, the base 10 is used to be fixedly connected to the packaging mechanism 70 and provide an installation position for the heating element 20, and the heating element 20 is used to melt and heat-seal the packaging bag. When the hot melt assembly 80 is actually used, the heating element 20 will contact the packaging bag to melt and seal the packaging bag. Since the cross-section of the heating element 20 in this embodiment is arranged in a broken line shape, that is, the heating element 20 has at least two hot melt surfaces, when the heating element 20 is squeezed with the packaging bag, at least two hot melt surfaces will form a hot melt mark with a certain width on the packaging bag, which can increase the area of ​​the hot melt area and improve the firmness of the seal, thereby improving the sealing effect of the packaging bag.

[0053] At the same time, since the cross-section of the heating element 20 in the embodiment is arranged in a broken line shape, when the hot melt assembly 80 in the present application is installed on the packaging mechanism 70, the heating element 20 can fuse the packaging bag currently in use with the packaging bag to be used next, and realize the sealing operation of the packaging bag currently in use to complete the packaging and packaging of the packaging bag. At the same time, it can also perform a sealing operation on the bottom of the packaging bag to be used next, so as to ensure the normal use of the packaging bag to be used.

[0054] Further, see Figure 3 to Figure 4 As shown, the heating element 20 in this embodiment includes a first heating section 21 and a second heating section 22, both of which extend along the first direction, and the first heating section 21 and the second heating section 22 are arranged in a V-shaped arrangement. Specifically, the arrangement of the first heating section 21 and the second heating section 22 can melt the packing bag and seal the melted packing bag, and the first heating section 21 and the second heating section 22 are arranged in a V-shaped arrangement, so that the sharp end of the V-shaped can cut the sealed packing bag.

[0055] That is to say, when the heating element 20 contacts the packing bag, the first heating section 21 and the second heating section 22 arranged in a V shape can fuse the packing bag currently in use with the packing bag to be used next, and the sealing operation of the packing bag currently in use is realized through the first heating section 21 and the second heating section 22 to complete the packing and packaging of the packing bag. At the same time, the bottom of the packing bag to be used next can also be sealed to ensure the normal use of the packing bag to be used. Among them, the first heating section 21 and the second heating section 22 will form a wider hot melt mark on the packing bag, which further increases the hot melt area compared to the hot melt component 80 in the prior art, thereby improving the firmness of the packing bag sealing, and then ensuring the sealing effect of the packing bag. In this way, during the packing process of the hot melt component 80 in this embodiment, the hot melt component 80 can complete the two functions of heat sealing and hot melting at one time, with a simple and reliable structure, and improves the sealing effect of the packing bag.

[0056] Further, see Figure 2As shown, the V-shaped opening end in this embodiment is arranged close to the base 10, and the V-shaped pointed end is arranged away from the base 10. Such an arrangement increases the contact area between the packing bag and the heating element 20, thereby improving the firmness of the packing bag sealing, ensuring the sealing effect of the packing bag to a certain extent, and at the same time, it can also complete the two functions of heat sealing and heat fusing at one time, and the structure is simple and reliable.

[0057] Further, see Figure 4 As shown, the sharp end of the V-shape in this embodiment is provided with a rounded corner 23. Specifically, since the present embodiment realizes the sealing and fusing of the packing bag by the heating element 20 arranged in a V-shape, at this time, the sharp end of the V-shape is provided with a rounded corner 23, which can prevent the packing bag from being damaged during the hot melting process, and effectively ensure the integrity and firmness of the packing bag seal.

[0058] Further, see Figure 3 to Figure 4 As shown, the first heating section 21 in this embodiment is provided as a first long strip, the first long strip extends along the first direction, and the first long strip has a first width D1, the first width D1 is greater than or equal to 1.9 mm, and less than or equal to 2.1 mm. That is to say, the first width D1 in this embodiment satisfies the relationship: 1.9 mm ≤ D1 ≤ 2.1 mm, such as 1.9 mm, 1.92 mm, 1.95 mm, 1.97 mm, 2 mm, 2.02 mm, 2.05 mm, 2.07 mm, 2.1 mm and any value therebetween. When the first width D1 is less than 1.9 mm, the contact area between the first heating section 21 and the packing bag is reduced, thereby reducing the area of ​​the hot melt area on the packing bag, and then reducing the firmness of the seal, and finally causing adverse effects on the sealing effect of the packing bag, making it difficult to ensure the sealing integrity of the packing bag; when the first width D1 is greater than 2.1 mm, the overall weight of the heating element 20 is increased, and the manufacturing cost of the heating element 20 is increased. That is to say, in this embodiment, by making the first width D1 satisfy the relationship: 1.9mm≤D1≤2.1mm, the sealing effect of the heating element 20 can be ensured. In addition, in this embodiment, the first heating section 21 is set as a sheet structure, so that the deformation degree of the first heating section 21 can be reduced, thereby avoiding the failure of the packaging bag due to deformation and distortion of the heating element 20.

[0059] Specifically, the first width D1 in this embodiment is preferably 2 mm.

[0060] Further, see Figure 3 to Figure 4As shown, the second heating section 22 in this embodiment is arranged as a second long strip, the second long strip extends along the first direction, and the second long strip has a second width D2, the second width D2 is greater than or equal to 1.9 mm, and less than or equal to 2.1 mm. That is to say, the second width D2 in this embodiment satisfies the relationship: 1.9 mm ≤ D2 ≤ 2.1 mm, such as 1.9 mm, 1.92 mm, 1.95 mm, 1.97 mm, 2 mm, 2.02 mm, 2.05 mm, 2.07 mm, 2.1 mm and any value therebetween. When the second width D2 is less than 1.9 mm, the contact area between the second heating section 22 and the packing bag is reduced, thereby reducing the area of ​​the hot melt area on the packing bag, and then reducing the firmness of the seal, and finally causing adverse effects on the sealing effect of the packing bag, making it difficult to ensure the sealing integrity of the packing bag; when the second width D2 is greater than 2.1 mm, the overall weight of the heating element 20 is increased, and the manufacturing cost of the heating element 20 is increased. That is to say, in this embodiment, by making the second width D2 satisfy the relationship: 1.9mm≤D2≤2.1mm, the sealing effect of the heating element 20 can be ensured. In addition, in this embodiment, the second heating section 22 is set as a sheet structure, so that the deformation degree of the second heating section 22 can be reduced, thereby avoiding the failure of the packaging bag due to deformation and distortion of the heating element 20.

[0061] Specifically, the second width D2 in this embodiment is preferably 2 mm.

[0062] Further, see Figure 1 As shown, in this embodiment, along the first direction, the two opposite ends of the base 10 are provided with a first receiving groove 30 and a second receiving groove 40, and the two opposite ends of the heating element 20 are respectively embedded in the first receiving groove 30 and the second receiving groove 40; wherein, the first receiving groove 30 and the second receiving groove 40 are both provided with a wiring terminal 50, and the two opposite ends of the heating element 20 are both connected to the wiring terminal 50. Specifically, the first receiving groove 30 and the second receiving groove 40 can limit and fix the wiring terminal 50 and the heating element 20, prevent the heating element 20 from falling off the base 10 during the use of the hot melt assembly 80, ensure the normal operation of the hot melt assembly 80, and improve the stability and reliability of the hot melt assembly 80; the setting of the wiring terminal 50 ensures the stable connection between the heating element 20 and the circuit.

[0063] Furthermore, the hot melt assembly 80 in this embodiment includes a heating wire 60, and the heating wire 60 and the heating element 20 are interchangeably arranged on the base 10; or, the hot melt assembly 80 also includes a heating wire 60, the heating wire 60 is arranged on the base 10 and extends along the first direction, the heating element 20 is covered and arranged on the side of the heating wire 60 away from the base 10, and the opposite ends of the heating wire 60 are respectively arranged in the first receiving groove 30 and the second receiving groove 40 and connected to the wiring terminal 50, wherein the first receiving groove 30 and the second receiving groove 40 can limit and fix the heating wire 60 to prevent the heating wire 60 from being detached during use. In other words, see Figure 1 to Figure 2 As shown, in one embodiment of the present application, the hot melt assembly 80 includes a base 10 and a heating element 20, and the heating element 20 is disposed on the base 10 and extends along a first direction; see Figures 5 and 6 As shown, in another embodiment of the present application, the hot melt assembly 80 includes a base 10 and a heating wire 60, and the heating wire 60 is disposed on the base 10 and extends along a first direction; see Figure 7 As shown, in another embodiment of the present application, the hot melt assembly 80 includes a base 10, a heating element 20 and a heating wire 60, the heating wire 60 and the heating element 20 are both arranged on the base 10 and extend along the first direction, and the heating element 20 is covered and arranged on the side of the heating wire 60 away from the base 10.

[0064] Specifically, when the hot melt component 80 includes a base 10 and a heating wire 60, the heating wire 60 forms a hot melt mark of a certain width on the packaging bag after contacting the packaging bag, which increases the area of ​​the hot melt region to a certain extent and improves the firmness of the seal; when the hot melt component 80 includes a base 10 and a heating element 20, the width of the hot melt mark formed on the packaging bag after the heating element 20 contacts the packaging bag is greater than the width of the hot melt mark formed by the heating wire 60, which further increases the area of ​​the hot melt region and effectively improves the firmness of the seal; when the hot melt component 80 includes a base 10, a heating wire 60 and a heating element 20, the heating element 20 covers the surface of the heating wire 60, so that the heat conduction efficiency can be improved and heat loss can be prevented.

[0065] Further, see Figure 6 As shown, the heating wire 60 in this embodiment comprises a circular heating wire. Such a configuration can make the heat generated by the heating wire 60 evenly distributed, avoiding local overheating and affecting the service life of the heating wire 60.

[0066] Further, see Figure 6As shown, the circular heating wire in this embodiment has a diameter D3, and the diameter D3 is greater than or equal to 0.6mm and less than or equal to 1mm. That is to say, the diameter D3 in this embodiment satisfies the relationship: 0.6mm≤D3≤1mm, such as 0.6mm, 0.65mm, 0.7mm, 0.75mm, 0.8mm, 0.85mm, 0.9mm, 0.95mm, 1mm and any value therebetween. When the diameter D3 is less than 0.6mm, it is difficult to maintain a stable working temperature during the hot melt process, which affects the packaging effect of the hot melt component 80. At the same time, the circular heating wire with a smaller diameter is prone to breakage or deformation during installation or use, shortening the service life of the circular heating wire; when the diameter D3 is greater than 1mm, the circular heating wire is prone to deformation, shortening the service life of the circular heating wire. That is to say, in this embodiment, by making the diameter D3 satisfy the relationship: 0.6mm≤D3≤1mm, the sealing effect of the circular heating wire on the packaging bag can be guaranteed, and at the same time, the circular heating wire can be prevented from deformation.

[0067] Furthermore, in this embodiment, a non-sticking cloth (not shown in the drawings) is provided on the side of the heating element 20 facing away from the base 10. Specifically, since the packaging bag in a molten state is easy to stick to the heating element 20, in this embodiment, a non-sticking cloth is provided on the heating element 20 to prevent the molten adhesive from sticking to the heating element 20, thereby effectively improving the hot melt effect and sealing effect of the heating element 20.

[0068] On the other hand, see Figures 8 to 13 As shown, the embodiment of the present application further provides a packaging mechanism, which includes the above-mentioned hot melt assembly, and therefore, the packaging mechanism includes all the technical effects of the above-mentioned hot melt assembly. Since the technical effects of the hot melt assembly have been described in detail above, they will not be repeated here.

[0069] Further, see Figures 8 to 13 As shown, the packaging mechanism 70 in this embodiment also includes a base (not shown in the drawings), a first installation body 71 and a second installation body 72.

[0070] Among them, the first installation body 71 is arranged on the first side of the base, and the first installation body 71 is provided with a hot melt component 80 and a first clamping portion 73, and the first clamping portion 73 is provided on the opposite sides of the hot melt component 80; the second installation body 72 is arranged on the second side of the base, and the second installation body 72 is provided with a top portion 75 and a second clamping portion 74, and the second clamping portions 74 are provided on the opposite sides of the top portion 75; wherein, at least one of the first installation body 71 and the second installation body 72 is movably arranged on the base, and the first installation body 71 and the second installation body 72 have a packaging position that abuts against each other. When the first installation body 71 and the second installation body 72 are in the packaging position, the first clamping portion 73 and the second clamping portion 74 are at least used to clamp the packaging bag, and the hot melt component 80 is at least used to hot-melt seal the packaging bag between the hot melt component 80 and the top portion 75.

[0071] Specifically, in the present application, when the packing mechanism 70 is actually processed, the first installation body 71 and the second installation body 72 are both arranged on the base, and the first installation body 71 is located on the first side of the base, and the second installation body 72 is located on the second side of the base, and the packing mechanism 70 also includes a bag box, in which a packing bag is placed. Before the packing mechanism 70 starts packing, the first installation body 71 and the second installation body 72 are respectively located on opposite sides of the packing bag, and when the excrement enters the packing bag, the first installation body 71 and / or the second installation body 72 are moved to press against the packing bag containing the excrement. When the first installation body 71 and the second installation body 72 move to the packing position, the first clamping part 73 and the second clamping part 74 abut against each other, so as to clamp the packing bag naturally drooping with the excrement, and at the same time, the hot melt assembly 80 and the abutting top 75 abut against each other to achieve hot melt sealing of the packing bag. At the same time, since the heating element 20 in this embodiment is arranged in a zigzag shape, that is, the heating element 20 has at least two hot-melt surfaces, when the heating element 20 is squeezed with the packaging bag, at least two hot-melt surfaces will form a hot-melt mark with a certain width on the packaging bag, which can increase the area of ​​the hot-melt area and improve the firmness of the seal, thereby improving the sealing effect of the packaging bag.

[0072] It can be understood that the settings of the first mounting body 71 and the second mounting body 72 in the present application include: (1) the first mounting body 71 can be movably set on the first side of the base, and the second mounting body 72 can be fixed on the second side of the base, so that the first mounting body 71 moves from the first side of the base toward the second side of the base; (2) the first mounting body 71 can be fixed on the first side of the base, and the second mounting body 72 can be movably set on the second side, so that the second mounting body 72 moves from the second side of the base toward the first side of the base; (3) the first mounting body 71 can be movably set on the first side of the base, and the second mounting body 72 can be movably set on the second side of the base, so that the first mounting body 71 and the second mounting body 72 can move toward each other.

[0073] Specifically, the first clamping portion 73 and the second clamping portion 74 in this embodiment both include foam or foamed silicone, and the first clamping portion 73 and the second clamping portion 74 are at least used to clamp the packing bag.

[0074] On the other hand, see Fig.14 As shown, the embodiment of the present application further provides a cat litter box, which includes the above-mentioned packing mechanism, and therefore, the cat litter box includes all the technical effects of the above-mentioned packing mechanism. Since the technical effects of the packing mechanism have been described in detail above, they will not be repeated here.

[0075] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0076] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0077] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
