Description

Technical Field

[0001] The utility model relates to a cat litter box, in particular to a device for detecting a state of a litter adding window of the cat litter box. Background Art

[0002] Cat litter boxes need to have a lid for easy litter addition. The lid can be opened or closed along a rotating shaft. For the safety of the cat, the lid needs to be tested to determine its status after it is opened or closed. The traditional method is to add a metal spring pin under the lid to electrically contact the corresponding metal surface on the lower shell for testing. This testing method has the following problems: (1) The spring pin or the corresponding metal surface of the lower shell will have poor contact after oxidation, resulting in detection failure. (2) Dirt on the metal surface will result in detection failure. (3) Assembly position deviation will result in detection failure.

[0003] It should be noted that the information disclosed in the above background technology section is only used for understanding the background of the present application, and therefore may include information that does not constitute prior art known to ordinary technicians in the field.

[0014] The utility model has the following beneficial effects:

[0015] Compared with the traditional electrical contact detection structure, the cat litter box sand adding window state detection device of the utility model has significant technical advantages. First, the device adopts a non-contact detection method, and realizes accurate detection of the opening and closing state of the sand adding window cover by using the Hall module and the magnet assembly. This method avoids the problem of poor contact caused by oxidation, dirtiness or assembly position deviation of the metal spring needle and the metal surface, thereby improving the reliability and stability of the detection. Secondly, the design of the device cleverly utilizes the principle of mechanical transmission formed by connecting the sand adding window rotating part with the magnet assembly, without complex circuit design or additional power connection, simplifying the overall structure and reducing the manufacturing and maintenance costs.

[0027] The cat litter box sand adding window state detection device of the utility model realizes accurate monitoring of the opening and closing state of the sand adding window cover through an innovative non-contact detection mechanism. Among them, the rotating parts, transmission parts, and magnet components of the sand adding window cover form a linkage system. When the sand adding window cover rotates, the magnet component moves accordingly, and the Hall module is responsible for sensing the position change of the magnet, thereby determining whether the sand adding window cover is in a closed or open state. The advantages of this solution are its high reliability and stability. The non-contact detection design avoids the failure problem caused by oxidation, dirt or assembly errors in the traditional electrical contact detection method. In addition, this design also avoids the trouble of taking electricity for detection on the upper cover, and also improves the safety of the cat litter box.

[0028] See also Figure 3 In a preferred embodiment, the rotating member 6 is a pivot of the sanding window cover 2 for mounting on the sanding window. In one embodiment, the sanding window cover 2 has a pair of metal shafts for mounting on the sanding window, and the rotating member 6 is formed by one of the metal shafts.

[0030] See also Figures 2 to 4 In one embodiment, the cantilever structure is a metal connecting bracket.

[0031] See also Figure 2 In a preferred embodiment, the Hall module 5 is arranged on the cat litter box middle shell below the cat litter box upper cover 1.

[0032] In some embodiments, the Hall module 5 is a Hall PCBA module formed on a PCBA.

[0033] The utility model also provides a cat litter box, which has a cat litter box sand window state detection device according to any of the above embodiments.

[0034] The following further describes the specific embodiments of the utility model and its working process.

[0035] like Figures 1 to 4 As shown, the tail of the sand adding window cover 2 is assembled with the cat litter box upper cover 1 by inserting two metal shafts. The sand adding window cover 2 uses the metal shaft as a rotating shaft and can be opened or closed on the sand adding window of the cat litter box upper cover 1; Figure 3As shown, one of the metal shafts inserted into the sanding window cover 2 is fixed together as a rotating member 6 and a metal connecting bracket as a transmission member 3 by screws, and the magnet assembly 4 is fixed together with the metal connecting bracket by screws; the metal shaft, the metal connecting bracket, the magnet assembly 4 and the sanding window cover 2 are assembled into an integrated module to form an integrated rotating mechanism, and the opening and closing action of the sanding window cover 2 causes the magnet assembly 4 to move synchronously. Figure 2 As shown, the Hall PCBA module is fixed at the corresponding position of the cat litter box shell. When the sand window cover 2 is in the closed state, the Hall PCBA module senses the magnet assembly 4, and the Hall PCBA module generates a signal to detect that the sand window cover 2 is in the closed state. When the sand window cover 2 is in the open state, the magnet assembly 4 is far away from the Hall PCBA module, so the Hall PCBA module cannot sense the signal, and it can be determined that the cover is in the open state.

[0036] Compared with the traditional electrical contact detection structure, the cat litter box sand window state detection device of the utility model has the following technical advantages:

[0037] The utility model adopts the Hall module and the magnet assembly for non-contact detection, avoiding the poor contact problem caused by metal spring needles or metal surface oxidation in traditional electrical contact detection. Since the detection mechanism does not rely on physical contact, the detection failure problem caused by dirty metal surfaces is reduced, and the reliability of detection is improved.

[0038] Different from the traditional electrical contact detection scheme, the detection device of the present invention does not require a strict assembly position, thereby reducing the risk of detection failure caused by assembly position deviation.

[0039] The Hall module and the magnet assembly are arranged in such a way that the detection mechanism can be hidden inside the cat litter box without affecting the appearance of the cat litter box, while maintaining the aesthetics and practicality of the cat litter box.

[0040] By using a combination of rotating parts, transmission parts and magnet components, the structure of the detection mechanism is simplified, the number of components is reduced, and the production cost and maintenance difficulty may also be reduced. Since the structure of the detection device is simplified and the number of components is reduced, maintenance and replacement work becomes easier and faster, thereby reducing long-term maintenance costs.

[0041] Since the detection mechanism does not rely on exposed metal contact points, the risk of electric shock is reduced, making the litter box safer to use.

[0042] In summary, the cat litter box and sand window status detection device of the utility model realizes non-contact detection, which not only improves the accuracy and reliability of detection, but also brings a series of technical advantages and market potential to the cat litter box through simplified design, hidden layout and enhanced user experience.

[0043] The above contents are further detailed descriptions of the present invention in combination with specific / preferred implementations, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, they can also make several substitutions or modifications to the described implementations without departing from the concept of the present invention, and these substitutions or modifications should be regarded as belonging to the protection scope of the present invention.
