Technical Field

[0001] The present invention relates to pet products, in particular to an airbag-type retractable combing device and a cat litter box. Background Art

[0002] Pet cats and dogs have a very long history of companionship with humans. In recent years, more and more families have started to keep pet cats and dogs. Pets have a shed period every year. If you do not comb your pets' hair regularly, hair will fly all over the house, which is neither hygienic nor beautiful. Therefore, you should comb your pets' hair regularly.

[0003] Cats currently make up a significant portion of household pets. To address cat hair loss and skin health, various manufacturers have designed a variety of grooming products, primarily combs. These products require manual handling to remove shed hair, debris, and other foreign matter, which takes up considerable time and can only be removed approximately two to three times per week. This creates a significant amount of shed hair that accumulates throughout the home, on furniture, and on clothing, making cleanup more difficult. Summary of the Invention

[0004] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and provide an airbag-type retractable combing device and a cat litter box that can automatically comb the hair, has a wide range of applications, and saves time and effort.

[0041] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0042] Example 1

[0043] like Figure 1-Figure 3 As shown, this embodiment provides an airbag-type retractable combing device, comprising a housing 3, an airbag 1, and a comb assembly 2. The housing 3 is a hollow, annular housing open at the front and back. A plurality of slots 301 are circumferentially distributed along the inner wall of the housing 3. The axes of the slots 301 pass through the axis of the housing 3, meaning that in an axial cross-section of the combing device, the slots 301 are evenly distributed along the center of the combing device. The airbag 1 is annular and is positioned between the slots 301 and the side of the housing 3. The airbag 1 is annular and its expansion amplitude is adjusted by the input / exhaust of air, serving as the power to adjust the up and down movement of the comb assembly. A comb assembly 2 is independently disposed within each slot 301 and is connected to the housing 3 via a spring 5. The airbag 1 is in contact with the comb assembly 2. The comb assembly can move up and down along the inner wall of the slot under the action of an external force. To enable the comb teeth to return to their original position after the airbag is expelled, the comb assembly 2 is connected to the housing 3 via a spring 5.

[0044] The airbag 1 can be connected to an external control device to expand or compress the airbag 1 according to a set expansion amplitude. In this embodiment, the external control device includes a control board and an air pump connected in sequence. The control board controls the operation of the air pump based on manual input signals or sensor information. The air pump adjusts the expansion amplitude of the airbag 1 according to a certain pressure, thereby driving the comb assembly 2 to move axially along the slot 301, causing the comb assembly 2 to extend or retract toward the hollow portion of the housing 3, thereby facilitating pet grooming when extended.

[0045] like Figure 4 As shown, the housing 3 in this embodiment is an annular structure, with its sides housing the airbag 1 and a hollow center serving as a passage for pets to enter and exit. Multiple slots 301 are provided on both inner walls of the housing 3. These slots 301 are staggered, allowing for the arrangement of two layers of comb assemblies 2, achieving faster and more efficient combing. In this embodiment, the slots 301 are square, giving the housing a square axial cross-section.

[0046] In another embodiment, the shell 3 wraps the airbag 1 on its side, and the shell 3 defines a through hole for connecting the airbag 1 to the air pump.

[0047] like Figure 5-Figure 6 As shown, the comb tooth assembly 2 of this embodiment includes a comb tooth seat 201 and comb teeth 202. One end of the comb tooth seat 201 is in contact with the airbag, and the other end is connected to a certain number of comb teeth 202. The comb tooth seat 201 matches the slot 301, and both ends of the comb tooth assembly 2 can pass through the slot 301.

[0048] In order to limit the travel of the comb tooth assembly 2, a first limit buckle 204 is provided on the comb tooth seat 201 of this embodiment, and a second limit buckle matching the first limit buckle 204 is provided on the slot 301. The first limit buckle 204 and the second limit buckle form a limiting mechanism for the movement process of the comb tooth assembly 2.

[0049] A comb tooth spring guide rod 203 for mounting the spring 5 is provided on the comb tooth seat 201 , and a housing spring guide rod 302 is provided corresponding to the slot 301 .

[0050] The end of the comb tooth seat 201 that contacts the airbag 1 is an arc-shaped surface, the width of which is greater than the width of the slot hole. The arc-shaped surface can cooperate with the end of the slot hole 301 to form a limiting mechanism.

[0051] In another embodiment, a hair removal stopper 4 is further provided in the slot 301, and the comb assembly 2 and the hair removal stopper 4 are arranged from outside to inside along the axis direction of the housing. Figure 7-Figure 9 As shown, the hair removal block 4 is provided with comb holes 401 for the comb assembly 2 to extend. The comb holes 401 are multiple parallel elongated holes with a width that matches the diameter of the comb teeth 202. When the comb assembly 2 completes combing and retracts, the hair removal block 4 separates the fallen hair from the comb assembly 2, achieving the purpose of more convenient and regular centralized cleaning of accumulated fallen hair. To increase the stroke of the comb assembly 2 and enable the hair removal block 4 to reset, each independent hair removal block 4 is connected to the housing 3 via a tension spring 6, and the hair removal block 4 is provided with a tension spring hook 402. The width of the area within the slot 301 where the hair removal block 4 is located is greater than the width of the area where the comb assembly 2 is located, preventing the hair removal block 4 from moving outward and failing to perform its function of blocking fallen hair.

[0052] In another embodiment, the airbag 1 is connected to a pressure detection sensor for detecting the pressure inside the airbag.

[0053] In another embodiment, at least one distance measuring sensor is provided on the housing 3 and can be connected to an external control device to control the extension length of the comb assembly 2 according to the measured distance.

[0054] The specific working process of the above-mentioned retractable combing device is as follows:

[0055] Taking the combing device in the initial state as an example, the airbag 1 is in a flat state, such as Figure 3 As shown, the comb assembly 2 is lifted to the highest position by the spring 5, and this highest position is controlled by the limiting structure arranged in the slot and cooperating with the comb assembly, and the hair removal stopper 4 below the comb assembly 2 is controlled by the tension spring 6 to be in a position close to the combing device shell; when the air bag 1 starts to inflate, it gradually fills up and increases from a flat state, and when it reaches a certain height, the pressure generated by the expansion of the air bag 1 will overcome the lifting force of the spring 5, and the comb assembly 2 will be driven downward along the inner wall of the slot (here the downward drive points to the direction of the hollow part of the shell), so that the comb teeth 202 gradually pass through the comb tooth through-holes 401 of the hair removal stopper 4. After the comb teeth 202 are exposed to a certain height, the combing effect can be produced. Figure 10 As shown; at this time, the airbag 1 continues to be pressurized, the comb assembly 2 continues to move downward, the lower end of the comb assembly 2 contacts the hair removal stopper 4, and gradually overcomes the tension of the tension spring 6, driving the hair removal stopper 4 to separate from the shell 3, and move toward the center of the circle together with the comb assembly 2. The hair removal stopper 4 and the comb assembly 2 move together to control the maximum length of the comb teeth to be within a reasonable range, and a part of the comb teeth length is located in the hair removal stopper 4 to avoid the comb teeth extending too long, the strength of the comb teeth being weakened, and affecting the comfort of the cat passing through the hair combing device. When the comb teeth 202 and the hair removal stopper 4 are After the hair stopper 4 moves to the maximum designed stroke, the downward limit mechanism formed by the arc surface at the top of the comb tooth assembly interferes with the shell, and the comb teeth 202 and the hair removal stopper 4 will no longer move downward. At the same time, the pressure detection sensor of the airbag 1 will also detect the pressure in the airbag. After reaching the warning value, it will stop further pressurizing the airbag to protect the airbag from being damaged by pressure; in the working state, the air pump of the airbag 1 will adjust the pressure in the airbag from time to time according to the data transmitted to the control board by the ranging sensor, and adjust the comb teeth to the appropriate height to achieve the most ideal combing effect.

[0056] After the combing device has been working for a period of time, a certain thickness of fallen hair, debris and other foreign matter has accumulated in the comb teeth 202. At this time, the combing device can be controlled to remove the accumulated foreign matter. The working principle is as follows:

[0057] When the control panel receives the command to clear the accumulated foreign matter, the air pump connected to the airbag 1 starts to work, continuously discharges the air in the airbag 1, and the airbag 1 gradually shrinks. At this time, the comb tooth assembly 2 gradually moves upward along the inner wall of the slot 301 under the action of the spring 5, and the hair removal block 4 moves in the same direction under the action of the tension spring 6, and gradually returns to its initial position close to the shell; at this time, the comb tooth assembly 2 continues to move upward, and the comb teeth 202 gradually shrink into the shell along the comb tooth through-holes 401 of the hair removal block 4, and foreign matter such as fallen hair accumulated on the comb teeth 202 is blocked outside the hair removal block 4 and is in a state of being completely separated from the combing device, so it can be conveniently collected and processed.

[0058] Example 2

[0059] This embodiment provides a cat litter box, including an airbag-type retractable combing device as in embodiment 1, the combing device forms an inlet and outlet channel of the cat litter box, as shown in FIG. Figure 11 A plurality of distance measuring sensors 7 are provided in the inlet and outlet passages. The distance measuring sensors 7 may be provided on the combing device or on another passage connected to the combing device. In this embodiment, the distance measuring sensors 7 are provided on the passage connected to the combing device.

[0060] When a cat enters the entrance and exit channel of a litter box with an integrated combing device, the distance measuring sensor in the channel will transmit the data of each point to the control board, and convert the data into the pressure value of the airbag in the combing device and transmit it to the air pump of the airbag to adjust the pressure in the airbag to the corresponding size, so as to achieve the purpose of adjusting the length of the comb teeth in the combing device and obtain a better combing effect.

[0061] The airbag-type retractable combing device described in Example 1 can also be used to comb the hair of other pets.

[0062] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art through logical analysis, reasoning, or limited experimentation based on the concepts of the present invention and the prior art should be within the scope of protection defined by the present invention.
