Description

Technical Field

[0001] The utility model relates to the technical field of baby products, and particularly refers to a milk powder stirrer. Background Art

[0002] In many families with babies, making milk powder is very common. Sometimes, the milk powder may pile up in hot water, and then the milk powder on the upper layer becomes sticky and covers the milk powder on the lower layer, making the milk powder unable to dissolve fully. The nutritional components in the prepared milk are insufficient, which also causes food waste, and the subsequent cleaning is rather troublesome.

[0003] With the progress of technology, many kinds of electric milk powder stirrers have been introduced on the market to help parents stir the milk powder in hot water quickly and fully, so that the milk powder can be dissolved in hot water completely.

[0004] The prior art still has the following deficiencies:

[0005] 1. Some milk powder stirrers on the market set a fixed stirring time and are controlled by a fixed switch. When parents encounter unexpected situations during the process of stirring milk powder, they may not be able to turn off the switch in time in a hurry, and the high-speed rotating stirring rod is easy to hurt people.

[0006] 2. Some milk powder mixers are relatively large in size. When in use, similar to using equipment such as coffee machines, it is necessary to place the container filled with milk powder and hot water below and then stir, and the operation is rather cumbersome and not very convenient to use. Content of the Utility Model

[0007] The purpose of the utility model is to provide a milk powder stirrer with a simple structure, convenient operation and easy control of the use state.

[0008] The purpose of the utility model is achieved as follows:

[0017] A reset member, which is placed inside the housing and is used to make the wiring part tend to move away from the battery assembly;

[0018] When the pressing assembly is pressed, the wiring part moves towards the front end of the housing, so as to abut against the battery assembly and realize the conduction of the circuit;

[0019] When the pressing assembly is released, under the action of the reset member, the wiring part does not contact the extreme of the battery assembly, realizing an open circuit.

[0020] Preferably, the pressing assembly further includes:

[0021] A pressing part, which is movably installed inside the housing and part of it is located outside the housing for the user to press;

[0022] The wiring part is arranged on the pressing part, and the end of the reset member abuts against the pressing part to keep the pressing part in a state of partially protruding from the housing.

[0023] Preferably, the pressing assembly further includes:

[0024] A fixing sleeve, which is movably installed at the rear end of the housing, and the pressing part, the wiring part and the reset member are all placed inside the fixing sleeve;

[0025] A fixing plate, which is installed at the front end of the fixing sleeve, and a wire outlet hole is formed on the fixing plate;

[0026] Both ends of the reset member abut against the fixing plate and the pressing part respectively;

[0027] When the pressing part is pressed, overcoming the acting force of the reset member, the end of the wiring part passes through the wire outlet hole to abut against the battery assembly.

[0028] Preferably, a locking working part is formed by recessing on the outer side of the fixing sleeve, and a disengaging area and a locking area are formed inside the locking working part;

[0029] A locking convex part is formed on the inner side of the housing. When the fixing sleeve is inserted into the housing, part of the locking convex part enters the locking convex part through the disengaging area;

[0030] After that, by rotating the fixing sleeve, the locking convex part can be moved to the locking area, so that the fixing sleeve is fixed at the end of the housing.

[0031] Preferably, a fixing groove is formed inside the pressing part, and the fixing groove is used to fix the wiring part.

[0032] Preferably, a first sleeving portion is formed on the fixing plate, and a second sleeving portion is arranged inside the pressing portion;

[0033] The reset member is a spring. The two ends of the reset member are respectively sleeved on the outer sides of the first sleeving portion and the second sleeving portion, so that the reset member is fixed between the fixing plate and the pressing portion.

[0034] Preferably, a locking groove is formed on the locking projection portion, and a locking protrusion is formed protruding inside the locking working portion;

[0035] When the locking protrusion is placed into the locking groove, the fixing sleeve is connected inside the housing.

[0040] The prominent and beneficial technical effects of the present utility model compared with the prior art are:

[0041] 1. In this technical solution, the movement of the wiring portion is driven by the pressing assembly, so that it can be controlled whether the wiring portion contacts the battery assembly, and thus it can be controlled whether an electric current loop is formed inside the stirrer. When the electric current loop is disconnected, the motor loses power and cannot continue to drive the stirring rod to work. And the pressing method enables parents to more conveniently control the working state of the pressing assembly during use.

[0042] 2. In this technical solution, after the pressing assembly is rotated by a certain angle, even if the pressing assembly is pressed again, the wiring portion and the battery assembly will not contact, thus avoiding accidental touch during normal times.

[0043] 3. When the product of this technical solution is in use, the housing is held by hand, and the product can be controlled by whether the thumb presses the pressing assembly. The structure is small and light, the operation method is simple, and it is convenient to control. Brief Description of the Drawings

[0055] The following are specific embodiments of the present utility model, and the technical solutions of the present utility model are further described in conjunction with the drawings, but the present utility model is not limited to these embodiments.

[0056] Embodiment 1:

[0057] As Figures 1 - 5A milk powder stirrer shown as follows includes:

[0058] A housing 1;

[0059] A motor 4, which is arranged inside the housing 1;

[0060] A stirring rod 5, the end of which is movably inserted into the front end of the housing 1 and is connected to the output shaft of the motor 4;

[0061] A battery assembly 3, which is arranged inside the housing 1 and is electrically connected to the motor 4;

[0062] A pressing assembly 2, which is arranged at the rear end of the housing 1 and movably abuts against the end of the battery assembly 3;

[0063] Among them, the pressing assembly 2 has:

[0064] A wiring part 6, which is movably placed inside the housing 1;

[0065] A reset part 24, which is placed inside the housing 1 and is used to make the wiring part 6 tend to move away from the battery assembly 3;

[0066] When the pressing assembly 2 is pressed, the wiring part 6 moves towards the front end of the housing 1, so as to abut against the battery assembly 3 and realize the conduction of the circuit. At this time, the motor 4 works to drive the stirring rod 5 to rotate. At this time, when the stirring end 51 of the stirring rod 5 is inserted into the water with milk powder, the stirring end 51 can perform the stirring work.

[0067] When the pressing assembly 2 is released, under the action of the reset part 24, the wiring part 6 moves towards the rear end of the housing 1, so that the wiring part 6 no longer contacts the extreme end of the battery assembly 3, realizing an open circuit. And the motor 4 loses power and cannot continue to drive the stirring rod 5 to rotate.

[0068] Through this solution, when the user puts down the stirrer, the stirrer can lose power and no longer drive the stirring rod 5 to rotate, thereby preventing the stirring rod 5 from colliding with other objects and being damaged or the high-speed rotating stirring rod 5 accidentally hurting people.

[0069] As a preferred embodiment, another extreme end of the battery assembly 3 is provided with a battery clip 31, and the battery clip 31 is communicated with a wiring post 41. Therefore, only by controlling the connection between the wiring part 6 and the extreme end of the battery assembly 3 can the entire circuit be disconnected or closed.

[0070] As Figures 1 - 6 shown, the pressing assembly 2 further includes:

[0071] A pressing part 21, which is movably installed inside the housing 1 and partially located outside the housing 1 for the user to press;

[0072] The wiring part 6 is arranged on the pressing part 21, and the end part of the reset part 24 abuts against the pressing part 21 to keep the pressing part 21 in a state of partially protruding from the housing 1.

[0073] As a preferred embodiment, the pressing assembly 2 can be arranged at the rear end of the housing 1. When the pressing part 21 is pressed, the pressing part 21 can move from the rear end of the housing 1 to the front end of the housing 1, so that the structure of the stirrer is simple and convenient for assembly.

[0074] As another preferred embodiment, the pressing part 21 can be arranged on the side surface of the housing 1.

[0075] Furthermore, the pressing assembly 2 further includes:

[0076] A fixed sleeve 23, which is movably installed at the rear end of the housing 1, and the pressing part 21, the wiring part 6 and the reset part 24 are all arranged inside the fixed sleeve 23;

[0077] A fixing plate 22, which is installed at the front end of the fixed sleeve 23, and a wire outlet hole 224 is formed on the fixing plate 22 for the wiring part 6 to pass through.

[0078] The wire outlet hole 224 can play a role in limiting and positioning.

[0079] The wire outlet hole 224 can reduce the deviation of the wiring part 6 during movement, so that the wiring part 6 can move accurately along the direction of the wire outlet hole 224. And the pole of the battery assembly 3 faces the wire outlet hole 224, so that after the wiring part 6 extends out of the wire outlet hole 224, it can stably abut against the pole of the battery assembly 3 to connect the circuit.

[0080] Both ends of the reset part 24 abut against the fixing plate 22 and the pressing part 21 respectively;

[0081] When the pressing part 21 is pressed, overcoming the acting force of the reset part 24, the end part of the wiring part 6 penetrates out of the wire outlet hole 224 to abut against the battery assembly 3.

[0082] When the pressing part 21 is released, the reset part 24 will push the pressing part 21 to reset and drive the wiring part 6 to move, so that the wiring part 6 no longer abuts against the pole of the battery assembly 3, achieving the purpose of disconnecting the circuit.

[0083] By arranging the fixed sleeve 23, the pressing part 21, the wiring part 6, the fixing plate 22 and the reset part 24 can be better connected into a whole, which is convenient for removing the pressing assembly 2 from the housing 1. Prevent the situation that the pressing part 21, the wiring part 6, the fixing plate 22 and the reset part 24 are scattered during the process of removing the pressing assembly 2 from the housing 1.

[0084] Specifically, such as Figure 2 and Figure 3As shown, a locking working part 231 is formed by concave molding on the outer side of the fixed sleeve 23, and a disengaging area 232 and a locking area 233 are formed in the locking working part 231.

[0085] A locking convex part 13 is formed on the inner side of the housing 1. The disengaging area 232 is communicated with the edge of the pressing part 21, so that when the fixed sleeve 23 is inserted into the housing 1, the locking convex part 13 can enter the locking convex part 13 through the disengaging area 232, and the fixed sleeve 23 can still rotate relative to the housing 1.

[0086] By rotating the fixed sleeve 23, the locking convex part 13 can be moved to the locking area 233. As the fixed sleeve 23 rotates, the locking convex part 13 can move from the disengaging area 232 into the locking area 233 and fix the locking convex part 13, so that the fixed sleeve 23 is connected to the end of the housing 1.

[0087] A locking groove 17 is formed on the locking convex part 13, and a locking convex block 239 is formed by protruding molding in the locking working part 231.

[0088] When the locking convex part 13 moves into the locking area 233 and the locking convex part 13 is fixed in the locking working part 231, the locking convex block 239 is placed into the locking groove 17, so that the fixed sleeve 23 is connected in the housing 1.

[0089] Specifically, as Figure 5 shown, a fixing groove 211 is formed in the pressing part 21. The fixing groove 211 is used to fix the wiring part 6. An interference fit is formed between the wiring part 6 and the fixing groove 211, so that the wiring part 6 can be fixed on the pressing part 21 and can move synchronously with the pressing part 21.

[0090] Furthermore, a first sleeving part 221 is formed on the fixing plate 22, and a second sleeving part 212 is arranged in the pressing part 21.

[0091] In the embodiment, the reset part 24 is a spring. The two ends of the reset part 24 are respectively sleeved on the outer sides of the first sleeving part 221 and the second sleeving part 212, so that the reset part 24 is fixed between the fixing plate 22 and the pressing part 21.

[0092] When the reset part 24 uses a spring, a part of the wiring part 6 can pass through the reset part 24, so that the reset part 24 can abut against the wiring part 6, thereby further fixing the position of the wiring part 6 in the pressing part 21 and preventing the wiring part 6 from slipping.

[0093] As Figures 1 - 6 shown, a plurality of claw fingers 222 are formed on the circumferential side of the fixing plate 22, and a plurality of clamping holes 234 are formed in the fixed sleeve 23. The claw fingers 222 can be clamped with the clamping holes 234, so that the fixing plate 22 is connected to the fixed sleeve 23.

[0094] A positioning convex portion 223 is formed by protruding on the peripheral side of the fixing plate 22, and a positioning groove 235 is formed on the fixing sleeve 23. The contour of the positioning convex portion 223 matches the positioning groove 235, so that the positioning convex portion 223 can be placed into the positioning groove 235.

[0095] Since the clamping claws 222 can be evenly distributed on the peripheral side of the fixing plate 22, in this case, when connecting the pressing portion 21, the fixing plate 22 and the fixing sleeve 23, since the situation inside the fixing sleeve 23 cannot be observed, it is impossible to determine whether the wiring portion 6 is aligned with the wire outlet hole 224.

[0096] If the wiring portion 6 is not aligned with the wire outlet hole 224, it is easy to squeeze the wiring portion 6 during the assembly process, resulting in deformation of the wiring portion.

[0097] Or,

[0098] The wiring portion 6 cannot match the position of the battery assembly 3, resulting in that when the user presses the pressing assembly 2, the wiring portion 6 cannot correctly contact the extreme end of the battery assembly 3, affecting the use of the product.

[0099] Through the cooperation of the positioning convex portion 223 and the positioning groove 235, it can help the user determine the position between the wiring portion 6 and the wire outlet hole 224 during assembly, so as to accurately complete the assembly and prevent the above situation from occurring.

[0100] As Figures 1 - 6 shown, a convex ring portion 236 is formed at the end of the fixing sleeve 23, and a plurality of anti-slip lines 237 are formed on the surface of the convex ring portion 236 to facilitate the user to rotate the fixing sleeve 23.

[0101] Furthermore, a state mark 25 is also formed on the surface of the convex ring portion 236, and an indication mark 18 is formed on the outer shell 1. When the indication mark 18 is aligned with different state marks 25, it can reflect the position of the locking convex portion in the locking working portion at this time, facilitating the user to determine the connection state between the fixing sleeve 23 and the outer shell 1.

[0102] As Figure 4 shown, the outer shell 1 is formed by splicing a front shell 11 and a rear shell 12. A support frame one 14 is formed inside the front shell 11, and a support frame two 15 is formed inside the rear shell 12;

[0103] When the front shell 11 and the rear shell 12 are connected to form an integral body, the outer shell 1 forms a motor cavity 19 for placing the motor 4, and the support frame one 14 and the support frame two 15 cooperate to form a battery cavity 16 for fixing the battery.

[0104] Embodiment 2:

[0105] This embodiment is basically the same as the first embodiment, except that:

[0106] A self-locking switch is provided on the pressing component 2. After the user presses it once, the pressing component 2 can keep itself in the on state, enabling the wiring part 6 to communicate with the battery component 3, without the user having to keep pressing the pressing component 2.

[0107] Pressing the pressing component 2 again can make the pressing component 2 in the off state, that is, the wiring part 6 is no longer in communication with the battery component 3.

[0108] Embodiment Three:

[0109] As Figure 7 shown, this embodiment is basically the same as the first embodiment, except that:

[0110] The locking working part 231 further includes a safety area. When the locking protrusion 13 is within the safety area, the housing 1 and the fixing sleeve 23 cannot be separated.

[0111] When the battery component 3 is two batteries arranged side by side, since the two batteries cannot completely cover the cross-section inside the housing. Therefore, when the end of the wiring part 6 is in the area not covered by the battery.

[0112] At this time, when pressing the pressing component 2, the wiring part 6 will not move into contact with the extreme of the battery component 3. Therefore, when the locking protrusion 13 is within the safety area, no matter how the user presses the pressing component 2, the stirring rod cannot be started, improving the safety during normal placement.

[0113] Embodiment Four:

[0114] This embodiment is basically the same as the first embodiment, except that:

[0115] The battery of the battery component 3 can be inserted into the housing 1 from the rear end of the housing 1. Therefore, after removing the pressing component 2 as a whole from one end of the housing 1, it is convenient for the user to install the battery into the interior of the housing 1.

[0116] Embodiment Five:

[0117] This embodiment is basically the same as the first embodiment, except that:

[0118] The battery of the battery component 3 can be a rechargeable battery, and a charging hole is provided on the housing 1 to facilitate charging the battery component 3.

[0119] Embodiment Six:

[0120] This embodiment is basically the same as the first embodiment, except that, specifically as Figure 6As shown, the stirring rod 5 is detachably connected to the drive shaft 42 of the motor 4 through the sleeving part 53, enabling the user to replace the stirring rod 5 with different shapes. For example, Figure 5 Figure 262 provides a schematic structural diagram of a stirring rod with a stirring end 52.

[0121] The matching structure between the sleeving part 53 and the drive shaft 42 is simple and easy to operate, facilitating the user to use the stirring rod 5.

[0122] The above embodiments are only the preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention shall be covered within the protection scope of the present invention.
