Description

Technical Field

[0002] Pet feeders have become a common item for feeding pets. With the continuous development of pet food, the variety of pet food has increased significantly. Pet food is mainly divided into two categories: wet food and dry food. Due to the economy and convenience of dry food, most pets currently eat it as their primary food. However, prolonged consumption of dry food can lead to insufficient water intake, which is detrimental to the pet's health. Therefore, wet food can provide pets with more comprehensive nutrition, and adequate water intake is also more beneficial to their health. However, wet food spoils easily, and how to store wet food in a feeder for a long time is a concern for many pet owners.

[0003] Currently, most food feeders on the market use frozen blue ice to preserve wet food. This method has a short shelf life. On the one hand, it requires freezing the blue ice and taking it out to put into the feeder every day, which is complicated and takes a lot of time to maintain. On the other hand, freezing blue ice can easily cause some wet food to become too cold in certain areas. Low temperatures can easily cause pets to experience indigestion, diarrhea, or bloating.

[0076] In addition, the terms "first", "second" are only used for description purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features.

[0077] Please refer to Figure 1 and Figure 2The pet feeder provided by the embodiment of the present application can place wet food and preserve the wet food, of course, the pet feeder can also place dry food, which is not limited herein. The pet feeder comprises a shell 2, a food tray 3, a food cover 4 and a driving mechanism 5.

[0078] Further in combination with Figure 7 The shell 2 is a hollow columnar structure, and the shell 2 is internally provided with a heat conduction sheet 11, a temperature adjusting structure 12 and a heat dissipation piece 13. The temperature adjusting structure 12 comprises a semiconductor refrigeration sheet 121 and a control module 122, and the two are connected together through a line. The semiconductor refrigeration sheet 121 has oppositely arranged first and second faces. The first face of the semiconductor refrigeration sheet 121 is connected with the surface of the heat conduction sheet 11, so that the cold or heat generated by the semiconductor refrigeration sheet 121 can be conducted through the heat conduction sheet 11. The second face of the semiconductor refrigeration sheet 121 is attached to the surface of the heat dissipation piece 13, so that the heat generated by the semiconductor refrigeration sheet 121 can be conducted through the heat dissipation piece 13. The control module 122 is used to control the first face of the semiconductor refrigeration sheet 121 to refrigerate or heat.

[0079] The food tray 3 is connected in the shell 2 and connected with the heat conduction sheet 11. The food tray 3 is provided with at least two food grooves 31, and each food groove 31 is placed with wet food to be preserved. The food cover 4 is provided with a window 41 in communication with one of the food grooves 31. When one of the food grooves 31 corresponds to the window 41, the pet can conveniently eat the wet food in the food groove 31 through the window 41.

[0080] The driving mechanism 5 is arranged in the shell 2. The driving end of the driving mechanism 5 is connected with the food tray 3, that is, the driving mechanism 5 can drive the food tray 3 to rotate. Alternatively, the driving end of the driving mechanism 5 is connected with the food cover 4, that is, the driving mechanism 5 can drive the food cover 4 to rotate. The working principle is as follows:

[0081] The semiconductor refrigeration sheet 121 is also called a thermoelectric semiconductor refrigeration sheet 1211 and starts to refrigerate or heat after being powered on. The first face of the semiconductor refrigeration sheet 121 is controlled to heat or cool by the control module 122. When refrigeration is needed, the control module 122 controls the first face of the semiconductor refrigeration sheet 121 to cool. When heating is needed, the control module 122 controls the first face of the semiconductor refrigeration sheet 121 to heat. The heating function can be realized without additionally setting a heating structure, the overall structure is relatively simple, and the cold or heat generated by the semiconductor refrigeration sheet 121 is transmitted to the food tray 3 through the heat conduction sheet 11, so that the temperature of the wet food in the food tray 3 is maintained within a certain temperature range, avoiding that the temperature of the wet food is too high in some places and too low in some places, thereby achieving a better preservation effect. In this embodiment, the semiconductor refrigeration sheet 121 can maintain the temperature within 10 degrees.

[0082] When the food tray 3 rotates, the wet food placed in each food groove 31 is rotated, and when one of the food grooves 31 corresponds to the window 41, the wet food in the food groove 31 is convenient for the pet to eat. Since the wet food is placed in each food groove 31, when the wet food in one of the food grooves 31 is eaten, the food tray 3 is continuously rotated until the next food groove 31 corresponds to the window 41, that is, through the relative rotation between the food tray 3 and the food cover 4, so that one of the food grooves 31 can be selectively aligned with the window 41, and the purpose of selective feeding is achieved. It can be understood that the food tray 3 rotates and the food cover 4 does not rotate, and the pet does not need to change position to eat the wet food in the food groove 31.

[0083] Of course, in other embodiments, when the food cover 4 rotates, that is, the food tray 3 does not rotate, the window 41 can be brought into correspondence with one of the food grooves 31, so that the pet can eat the wet food in the food groove 31 through the window 41, as long as the purpose of selective feeding is achieved, which is not limited herein. It can be understood that the food cover.

[0084] The pet feeder provided by the application has the following beneficial effects compared with the prior art:

[0085] In a first aspect, the first surface of the semiconductor refrigeration sheet 121 is heated or cooled by the control module 122, which has a simple structure and does not require additional heating structure to complete the heating function, thereby heating or cooling the wet food, solving the technical problem of complicated operation caused by using frozen blue ice for preservation, and achieving simple operation and good preservation effect by avoiding that some places of the wet food have too high temperature and some places have too low temperature.

[0086] In a second aspect, the driving mechanism 5 drives the food tray 3 or the food cover 4 to rotate, and a plurality of food grooves 31 are formed on the food tray 3, so that one of the food grooves 31 can be selectively aligned with the window 41, achieving the purpose of selective feeding.

[0087] In the embodiment, the semiconductor refrigeration sheet 121 utilizes the Peltier effect of semiconductor materials, and when direct current passes through an electric couple formed by series connection of two different semiconductor materials, heat can be absorbed and released at both ends of the electric couple, achieving the purpose of refrigeration or heating. It should be noted that the switching time of the control module 122 for controlling the semiconductor refrigeration sheet 121 to refrigerate or heat is realized by a switch or a timer. The heat conduction sheet 11 has a fan-shaped structure and is made of aluminum, which has low cost and good heat conduction or heat dissipation effect.

[0088] In one embodiment of the present application, please refer to 9, the control module 122 comprises a drive chip 1221, a controller 1222 and a power supply 1223, the drive chip 1221 is electrically connected with the semiconductor refrigeration piece 121, the controller 1222 is electrically connected with the drive chip 1221, the controller 1222 controls the forward and reverse conduction of the semiconductor refrigeration piece 121 through the drive chip 1221, and the power supply 1223 is electrically connected with the drive chip 1221 and used for supplying power to the drive chip 1221.

[0089] Wherein, the controller 1222 is electrically connected with the drive chip 1221 through a first control line 123 and a second control line 124, the drive chip 1221 is electrically connected with the semiconductor refrigeration piece 121 through a first output line 125 and a second output line 126, the drive chip 1221 is powered by the power supply 1223, the first control line 123, the second control line 124, the first output line 125 and the second output line 126 output signals are controlled, and the controller 1222 changes the positive and negative polarity of the output by changing the port state of the first control line 123 and the second control line 124. For example, the controller 1222 controls the first control line 123 to be 1 and the second control line 124 to be 0, so that the first output line 125 outputs positive and the second output line 126 outputs negative, at this time, the semiconductor refrigeration piece 121 works in the refrigeration state, that is, the surface of the semiconductor refrigeration piece 121 facing the heat conduction sheet 11 is the cold surface; on the contrary, when the controller 1222 controls the first control line 123 to be 0 and the second control line 124 to be 1, the first output line 125 outputs negative and the second output line 126 outputs positive, then the semiconductor refrigeration piece 121 works in the heating state, that is, the surface of the semiconductor refrigeration piece 121 facing the heat conduction sheet 11 is the hot surface.

[0090] In one embodiment of the present application, please refer to Figure 7 , the heat conduction sheet 11, the semiconductor refrigeration piece 121 and the heat dissipation piece 13 are located on the same plane, in this embodiment, when the shell is placed on the ground or the desktop, the plane is a horizontal plane, wherein the heat conduction sheet 11, the semiconductor refrigeration piece 121 and the heat dissipation piece 13 can be arranged in sequence on the same straight line, of course, they can also be arranged in a curve, as long as the heat conduction sheet 11, the semiconductor refrigeration piece 121 and the heat dissipation piece 13 can be attached together, avoiding that the three are stacked in sequence along the height direction of the shell 2, causing the three to be accumulated together under the action of gravity and causing heat accumulation, and avoiding increasing the overall thickness of the feeder.

[0091] In one embodiment of the present application, please refer to Figure 2 and Figure 3The driving mechanism 5 comprises a driving member 51 and a transmission assembly 6. The driving member 51 is arranged in the housing 2, wherein the driving member 51 has the driving end described above, which is connected with the feeding disc 3 for driving the feeding disc 3 to rotate relative to the housing 2. The transmission assembly 6 is arranged in the housing 2 and is drivingly connected between the feeding disc 3 and the driving member 51, so that the feeding disc 3 can be stably rotated through the transmission assembly 6. Specifically, the driving member 51 can be a driving motor, and the output end of the driving motor is drivingly connected with the transmission assembly 6, so as to drive the feeding disc 3 to rotate. The movement of the driving member 51 is transmitted through the transmission assembly 6, so that a driving member 51 with smaller size can be adopted, and the cost can be saved to a certain extent.

[0092] Further, the feeding disc 3 is arranged in a spaced manner with the heat conduction sheet 11, i.e. the feeding disc 3 is in a clearance fit with the heat conduction sheet 11. In the embodiment, the clearance between the feeding disc 3 and the heat conduction sheet 11 can be between 0.5mm and 1.5mm. In specific applications, the clearance between the feeding disc 3 and the heat conduction sheet 11 is 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm or 1.5mm. The feeding disc 3 is in a clearance fit with the heat conduction sheet 11, so as to avoid that the feeding disc 3 transmits the movement to the heat conduction sheet 11 during rotation, which causes the heat conduction sheet 11 to be deformed by friction, and also avoids that the clearance between the feeding disc and the heat conduction sheet 11 is too large to cause the cold energy to be unable to be transmitted to the feeding disc 3.

[0093] Further, in the embodiment, the transmission assembly 6 is a worm gear transmission, so that the transmission between the two intersecting shafts can be realized without occupying the size in the height direction of the feeder. Specifically, the transmission assembly 6 comprises a rotating shaft 61, a first worm gear 62, a first worm 63, a second worm gear 64 and a second worm 65. The rotating shaft 61 is arranged in the housing 2 along the axial direction of the housing, the first end of the rotating shaft 61 is connected with the housing 2, the second end of the rotating shaft 61 penetrates through the feeding disc 3, the first worm gear 62 is coaxially sleeved on the first end of the rotating shaft 61. The tooth groove can be formed on the outer circumferential surface of the rotating shaft 61 to form the worm gear, i.e. the rotating shaft 61 and the first worm gear 62 are integrally formed. Of course, the worm gear and the rotating shaft 61 can also be arranged as a split structure and can be detached, so as to facilitate replacement.

[0094] The first worm 63 is arranged on one side of the rotating shaft 61 and extends in a direction perpendicular to the axis of the rotating shaft 61, the first worm 63 is in meshing transmission with the first worm wheel 62; the second worm wheel 64 is coaxially sleeved on the first worm 63; the second worm 65 extends in a direction perpendicular to the axis of the first worm 63 and the axis of the rotating shaft 61, the second worm 65 is in meshing transmission with the second worm wheel 64, and one end of the second worm 65 away from the second worm wheel 64 is coaxially connected with the driving end of the driving member 51. When the driving end of the driving member 51 rotates, the second worm 65 is driven to rotate, the second worm 65 drives the second worm wheel 64 to rotate, the second worm wheel 64 is sleeved on the first worm 63, thereby driving the first worm 63 to rotate, the first worm 63 drives the first worm wheel 62 in meshing transmission to rotate, the first worm wheel 62 is arranged on the rotating shaft 61, thereby driving the rotating shaft 61 to rotate, and further driving the food tray 3 to rotate. By adopting the first worm wheel 62, the first worm 63, the second worm 65 and the second worm wheel 64, that is, by two-stage transmission, the rotating speed of the rotating shaft 61 can be reduced, and on the other hand, the first worm 63 arranged on one side of the rotating shaft 61 can avoid increasing the thickness of the whole pet feeder.

[0095] Of course, in other embodiments, the transmission assembly 6 can only include the rotating shaft 61, the first worm wheel 62 and the first worm 63, and the end of the first worm 63 is connected with the driving end of the driving member 51, that is, one-stage transmission is realized.

[0096] Further, in order to realize the purpose of timed feeding, the pet feeder further includes a control panel (not shown in the figure) and a circuit board (not shown in the figure), the circuit board is arranged at one end of the rotating shaft 61 penetrating the food tray 3, the control panel is arranged on the side of the circuit board away from the rotating shaft 61 and is electrically connected with the circuit board, and the control panel is provided with operation buttons, for example, the operation buttons can be timing buttons, when the rotating time is set, the circuit board controls the driving member 51 to rotate in a timed manner, thereby realizing automatic feeding.

[0097] It should be noted that one end of the rotating shaft 61 protrudes out of the food tray 3 but does not penetrate the food cover 4, in order to facilitate the operation of the control panel and also to avoid the pet from misoperating when eating wet food, the food cover 4 is provided with a protective cover 9 corresponding to the position of the operation panel, the protective cover 9 is detachably connected with the food cover 4, and the protective cover 9 is convenient to detach to operate the operation panel.

[0098] In another embodiment of the present application, please refer to Figure 4 and Figure 5The food tray 3 comprises a body part 32 and at least one inserting part 33. The body part 32 is provided with at least two food grooves 31, and a connecting through hole 34 is formed in the body part 32 for the second end of the rotating shaft 61 to pass through. The at least two food grooves 31 are arranged around the connecting through hole 34, i.e. the connecting through hole 34 is arranged at the middle position of the body part 32. Each inserting part 33 is connected with the body part 32 and extends towards the direction of the rotating shaft 61. The at least one inserting part 33 is arranged around the connecting through hole 34, and an inserting groove 610 is formed in the outer circumferential wall of the rotating shaft 61 for the inserting part 33 to insert into. By inserting the inserting part 33 into the inserting groove 610, the food tray 3 and the rotating shaft 61 are connected.

[0099] In specific applications, the number of the at least one inserting part 33 is one, two or more. In order to achieve more stable connection, the number of the inserting part 33 is multiple. Of course, in other embodiments, an inserting groove can be arranged on the food tray 3, and an inserting part is arranged on the rotating shaft 61. By matching the inserting part with the inserting groove, the food tray 3 and the rotating shaft 61 are connected.

[0100] In another embodiment of the present application, please refer to Figure 2 and Figure 7 The pet feeder further comprises a middle frame 7 and a first heat insulation part 8. The middle frame 7 is arranged on the side of the food tray 3 facing the shell 2, and a first containing cavity is formed between the middle frame 7 and the shell 2. The heat dissipation part 13 and the semiconductor refrigeration sheet 121 are arranged in the first containing cavity.
