Abstract
Description
Technical Field
[0001] This application relates to the field of cat litter box technology, and in particular to a cat litter box drying and deodorizing device and a cat litter box. Background Technology
[0002] Currently, pet litter boxes on the market often have a serious odor problem. The litter collection chambers are not properly sealed, allowing odors to escape. When consumers remove the litter collection chamber, the odor significantly impacts the home environment and their health. For example, a pet toilet air purification device disclosed in announcement number CN118415082A includes a pre-filter module, a plasma tube, activated carbon, a fan, a negative ion module, and an atomizing liquid module. The fan creates negative pressure inside the litter box, filtering hair and large particles of debris through the pre-filter module. Odors and harmful gases in the litter box are decomposed by the plasma tube, and activated carbon absorbs some of the odors and harmful gases. The negative ion module purifies the gas after treatment by the plasma tube and activated carbon. The purified gas is then discharged to the outside of the device along with the atomized liquid generated by the atomizing liquid module. Utility Model Content
[0003] The purpose of this application is to provide a drying and deodorizing device for a cat litter box and a cat litter box.
[0004] The embodiments of this application adopt the following technical solution: a drying and deodorizing device for a cat litter box, comprising:

[0031] Various embodiments and features of this application are described herein with reference to the accompanying drawings.
[0032] It should be understood that various modifications can be made to the embodiments described herein. Therefore, the above description should not be considered as limiting, but merely as an example of embodiments. Other modifications within the scope and spirit of this application will be apparent to those skilled in the art.
[0033] The accompanying drawings, which are included in and form part of this specification, illustrate embodiments of the present application and, together with the general description of the present application given above and the detailed description of the embodiments given below, serve to explain the principles of the present application.
[0034] These and other features of this application will become apparent from the following description of preferred forms of embodiments given as non-limiting examples, with reference to the accompanying drawings.
[0035] It should also be understood that although this application has been described with reference to some specific examples, those skilled in the art can certainly implement many other equivalent forms of this application.
[0036] The above and other aspects, features and advantages of this application will become more apparent when taken in conjunction with the accompanying drawings and in view of the following detailed description.
[0037] Specific embodiments of this application are described thereafter with reference to the accompanying drawings; however, it should be understood that the claimed embodiments are merely examples of this application, which can be implemented in various ways. Well-known and / or repeated functions and structures are not described in detail to avoid unnecessary or redundant details that could obscure the application. Therefore, the specific structural and functional details claimed herein are not intended to be limiting, but merely serve as the basis and representative basis for the claims to teach those skilled in the art to use this application in a variety of substantially any suitable detailed structures.
[0038] This specification may use the phrases “in one embodiment,” “in another embodiment,” “in yet another embodiment,” or “in other embodiments,” all of which may refer to one or more of the same or different embodiments according to this application.
[0039] To address the problems in the background art, this application provides a drying and deodorizing device 08 for a cat litter box, which can dry and deodorize the clumps in the cat feces collection compartment 05 of the cat litter box.
[0040] Cat urine and feces clump together when they come into contact with cat litter. This clumping, placed in the feces collection bin 05, tends to emit a foul odor over a prolonged period due to its moisture content, impacting environmental quality and the health of users. Therefore, the drying and deodorizing device 08 of this application heats and sterilizes the air inside the feces collection bin 05, thereby drying the wet clumps. The dried clumps are less likely to emit a foul odor.
[0041] like Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the drying and deodorizing device 08 includes a housing, a heating module 11, a filter module, and a fan 16. At least the heating module 11 and the fan 16 in the drying and deodorizing device 08 are connected to the power module 06 of the litter box, and the power module 06 provides power to the heating module 11 and the fan 16. The power module 06 can be a battery with power storage capacity.
[0042] The outer casing has a cavity for housing the heating module 11, the filter module, and the fan 16. The cavity of the outer casing is adapted to the shape of the heating module 11, the filter module, and the fan 16 to accommodate the above structures, thereby reducing the size of the outer casing and reducing the space occupied by the drying and deodorizing device 08 on the overall cat litter box 01.
[0043] The heating module 11 can be installed inside the receiving cavity; for example, it can be fixed inside the receiving cavity with screws. Alternatively, other connection methods can be used to install the heating module 11 inside the receiving cavity. The heating module 11 can be used to heat the air entering the housing, specifically the air from the cat litter box's feces collection compartment 05, raising the air temperature to a certain range and removing moisture from the air.
[0044] The filter module is detachably mounted on the outer casing and is used to filter the air entering the casing. Here, the filter module can sterilize and deodorize the air entering the casing, removing odors and preventing them from affecting ambient air quality.
[0045] The fan 16 can also be installed within the receiving cavity, for example, by fixing the fan 16 to the receiving cavity with screws. Of course, it is understood that the fan 16 can also be installed within the receiving cavity in other ways. This is merely an example and does not constitute a limitation on the scope of the claims.
[0046] like Figure 4 As shown, the fan 16 draws air from the litter box's fecal collection chamber 05 into the outer casing, and returns the heated air (after being heated by the heating module 11 and filtered by the filter module) to the fecal collection chamber 05 to dry the clumps inside. The heated air, after being heated by the heating module 11, enters the fecal collection chamber 05 and dries the wet clumps. After a period of cyclical drying, the wet clumps in the fecal collection chamber 05 gradually dry out. The dried clumps are less likely to emit odors, thus achieving the drying and deodorizing effect of the litter box.
[0047] The working time of the drying and deodorizing device 08 can be set according to needs. For example, if there is a lot of clumping, the working time of the drying and deodorizing device 08 can be increased, and if there is less clumping, the working time of the drying and deodorizing device 08 can be decreased. Users can also set the working time of the drying and deodorizing device 08 based on experience.
[0048] In addition, the air is constantly flowing under the action of the fan 16, and the odor is also removed by the filtration process of the filter module.
[0049] In this application, the filter module is detachably mounted on the housing and can be replaced as needed to ensure the filter module's air filtration function.
[0050] In summary, this embodiment of the application heats the air inside the cat feces collection chamber 05 using the heating module 11, thereby drying the clumps inside the chamber and reducing odor emissions. Additionally, the filtration module filters out hair and odors from the air, making the air inside the cat feces collection chamber 05 cleaner and further reducing odor emissions.
[0051] In some embodiments, the heating module 11 includes a PTC (Positive Temperature Coefficient Heater), a semiconductor heater, or a heating wire heater. Specifically, it can be configured as needed. Of course, the heating module 11 can also use other heaters to heat the air inside the housing. The aforementioned heaters can quickly start heating as needed, improving the heating efficiency of the heating module 11 in heating the air.
[0052] In some embodiments, such as Figure 6 , Figure 7 and Figure 8As shown, the filter module includes a filter cotton 15 and a mounting base 17. The filter cotton 15 is detachably mounted on the mounting base 17, and the mounting base 17 is detachably mounted on the housing. For example, the mounting base 17 may have a slot for mounting the filter cotton 15. The filter cotton 15 may be a block with a certain thickness, and the filter cotton 15 can be secured in the slot of the mounting base 17. The filter cotton 15 has a certain degree of deformability; therefore, the thickness of the filter cotton 15 can be slightly greater than the thickness of the slot, so that the filter cotton 15 can be securely secured in the slot.
[0053] The outer shell can be designed as a cuboid shell, and the filter cotton 15 can be set as a cube corresponding to the cross-sectional shape and size of the receiving cavity of the outer shell. The outer edge of the filter cotton 15 (except for the part inside the slot) can be attached to the inner wall of the receiving cavity to improve the filtration effect of the air passing through the outer shell and prevent the air inside the outer shell from returning to the cat feces collection box 05 without being filtered by the filter module.
[0054] The filter cotton 15 includes adsorbent materials for odor absorption, such as activated carbon or other materials that absorb odors. The filter cotton 15 also filters lint and other fibrous materials, preventing cat hair from entering the surrounding environment.
[0055] The mounting base 17 may be made of plastic sheet, and a portion of the mounting base 17 may be located outside the housing to facilitate the installation and removal of the mounting base 17. For example, the mounting base 17 may include a handle, which can be pinched to push the mounting base 17 into the receiving cavity or remove the mounting base 17 from the receiving cavity when installing and removing the mounting base 17 (and the filter cotton 15 disposed on the mounting base 17).
[0056] The detachable filter module allows for the removal and replacement of the filter cotton 15 as needed, ensuring effective air deodorization and preventing a decrease in the filter module's filtration efficiency due to prolonged use, which would then affect the removal of odors.
[0057] In some embodiments, the receiving cavity has an opening communicating with the outside, through which the filter module extends into the receiving cavity, and the mounting base 17 is secured to the housing.
[0058] For example, an opening can be provided in the middle (or other position) of the housing cavity, the shape and size of which correspond to the shape and size of the filter module. The filter cotton 15 on the mounting base 17 is pushed into the housing cavity from the opening. When the filter cotton 15 is installed in place, the mounting base 17 can be locked in the opening position, that is, the housing can lock the mounting base 17 through the opening.
[0059] To disassemble the filter module, simply pull the mounting base 17 outwards. The removed filter module allows for the replacement of the filter cotton 15. After replacing the filter cotton 15, the filter module can be reinstalled into the receiving cavity. This process is convenient and easy to implement. The filter module can be quickly removed from the outer casing as needed, facilitating rapid replacement of the filter cotton 15.
[0060] In some embodiments, the housing includes a main housing 14 and a top cover 12, the top cover 12 being disposed on the main housing 14 and enclosing the main housing 14 to form a receiving cavity. For example, the top cover 12 can be fixed to the main housing 14 by screws or by plug-in connection. When it is necessary to clean or repair the structural components inside the receiving cavity, the top cover 12 can be separated from the main housing 14.
[0061] This embodiment allows users or maintenance personnel to disassemble the outer shell as needed, facilitating the cleaning or maintenance of the various structural components inside the cavity.
[0062] In some embodiments, the housing has an air inlet, such as Figure 7 As shown, the heating module 11 is located at the air inlet. Air from the cat feces collection chamber 05 can enter the outer casing through the air inlet. The heating module 11 can heat the air that just enters the casing, and the heated air is then sent to the filter module for filtration to prevent humid air from affecting the filtration effect of the filter module.
[0063] Or such as Figure 8 As shown, the fan 16 is placed at the air inlet. The fan 16 can blow the air entering the housing toward the filter module and dry the filter module to ensure the filtration effect of the filter module.
[0064] In some embodiments, the litter box drying and deodorizing device 08 further includes a conduit 13. The outer casing has an exhaust port, and one end of the conduit 13 communicates with the exhaust port. For example, the outer casing can be provided with an exhaust pipe, which can be installed on the top cover 12 and has an exhaust port. The exhaust pipe extends outward, and one end of the conduit 13 is placed on the exhaust pipe. The two can be sealed together to prevent air leakage. The conduit 13 can be made of a plastic flexible hose, which facilitates the installation of the conduit 13 and the sealing connection with the exhaust pipe.
[0065] A connecting hole can be provided on the base 04 of the litter box. The air inlet of the outer shell can be connected to the connecting hole, allowing air in the cat feces collection chamber 05 to enter the air inlet of the outer shell after passing through the connecting hole.
[0066] like Figure 4 The other end of the conduit 13 can be connected to the air outlet on the base 04 of the litter box, and the air outlet is connected to the feces collection bin 05, which is detachably mounted on the base 04 of the litter box. The conduit 13 can be installed on the base 04.
[0067] The other end of the duct 13 can extend to the air outlet of the base 04, or extend into the cat litter collection chamber 05. The duct 13 can more quickly and accurately deliver the filtered and heated air inside the housing back to the cat litter collection chamber 05, improving air circulation efficiency.
[0068] For example, the air in the cat feces collection chamber 05 enters the drying and deodorizing device 08 through the left side of the cat feces collection chamber 05. After being heated and filtered, the air returns to the cat feces collection chamber 05 from the rear side through the duct 13, realizing the circulation heating and filtration of the air.
[0069] This application also provides a cat litter box, including the drying and deodorizing device 08 as described in any of the above embodiments, to remove odors from the cat litter box.
[0070] In some embodiments, combined with Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the complete cat litter box 01 also includes a base 04, a litter collection chamber 05, a main body assembly 02, and a litter working chamber assembly 03. The litter collection chamber 05 can be a basin-shaped structure with an open top. The litter working chamber assembly 03 is used to hold cat litter and can be mounted on the main body assembly 02. The main body assembly 02 and the drying and deodorizing device 08 can be mounted on the base 04 respectively. The base 04 can have multiple support legs 07, each with a certain height, and can be supported on the ground. The litter collection chamber 05 can be mounted on the base 04, positioned between the support legs 07. The litter collection chamber 05 can be pushed and pulled onto the base 04, or mounted on the base 04 in other ways. When it is necessary to empty the clumps and litter in the litter collection chamber 05, the litter collection chamber 05 can be removed from the base 04; after emptying, the litter collection chamber 05 can be installed back onto the base 04.
[0071] The drying and deodorizing device 08 is located below the cat litter working chamber assembly 03. The bottom of the cat litter working chamber assembly 03 is equipped with a mechanical chamber door 09. When the drying and deodorizing device 08 is started, the mechanical chamber door 09 is closed so that the internal space of the cat litter collection chamber 05 and the drying and deodorizing device 08 can form an air circulation space. When the heating module 11 and the fan 16 of the drying and deodorizing device 08 are started, the air in the cat litter collection chamber 05 can be drawn into the drying and deodorizing device 08 for heating, mainly to dry the air in the cat litter collection chamber 05, so as to quickly dry the clumps in the cat litter collection chamber 05.
[0072] The drying and deodorizing device 08 can be installed on the outside of the open top of the cat feces collection bin 05 and fixed to the base 04 with screws. Of course, other installation methods can also be used to install the drying and deodorizing device 08 on the base 04.
[0073] As mentioned earlier, the air in the cat feces collection chamber 05 enters the drying and deodorizing device 08 through the left side of the cat feces collection chamber 05. After being heated and filtered, the air returns to the cat feces collection chamber 05 from the rear side through the duct 13, realizing the circulation, heating and filtration of the air.
[0074] The main body component 02 can be equipped with buttons for starting / stopping the drying and deodorizing device 08, as well as buttons for adjusting the working time of the drying and deodorizing device 08.
[0075] The foregoing has described in detail several embodiments of this application, but this application is not limited to these specific embodiments. Those skilled in the art can make various variations and modifications based on the concept of this application, and all such variations and modifications should fall within the scope of protection claimed in this application.
