Description

Technical Field

[0001] The utility model relates to the field of bubble machines, in particular to a bubble machine. Background Art

[0002] A bubble machine is a children's toy that uses air to squeeze bubble liquid to produce a large number of bubbles. There are many types of existing bubble machines, such as a handheld bubble machine that can produce bubbles by pulling its trigger. Another example is a kaleidoscope type, which can spray a large number of bubbles by pressing its switch and rotating the kaleidoscope.

[0003] However, the existing bubble machines only have entertainment functions, and are not combined with other elements, such as sports, competitions and other elements. They have a single function and are easy to lose interest after being used for a period of time, so the usage rate is not high. Utility Model Content

[0004] In view of the defects in the prior art, the invention integrates sports and competitive elements, and allows entertainment and sports to be carried out simultaneously to improve the fun. The utility model provides a bubble machine, including a base, a foot pedal, a telescopic cylinder, an electric bubble machine and a sensor; two foot pedals are provided, and the front ends of the two foot pedals are respectively hinged to the left and right sides of the base, and a telescopic cylinder is provided between each foot pedal and the base, and each telescopic cylinder is inclined upward and backward, and the base is provided with a first limit assembly that enables the two foot pedals to be linked, and by pressing down any one of the foot pedals and retracting the telescopic rod of the corresponding telescopic cylinder, the other foot pedal is synchronously swung upward around the hinge point under the elastic force of the corresponding telescopic cylinder;

[0005] One of the two foot pedals is provided with a sensing element adapted to the sensor, the bubble machine and the sensor are both mounted on a base, and the detection end of the sensor faces the direction of the sensing element; the bubble machine and the sensor are electrically connected, and the sensing element swings up and down with the corresponding foot pedal, so that the sensing element reciprocates through the detection end of the sensor to control the bubble speed of the bubble machine.

[0006] The beneficial effect of the utility model is that the user's feet step on the two pedals. Due to the restriction of the first limit assembly, when one foot steps down, the other foot is lifted up, and the two feet step up and down alternately. The amplitude of the two pedals swinging up and down is captured by the sensor. The larger the amplitude, the faster the bubble machine blows out bubbles, and the two are proportional. Compared with a simple bubble machine, it combines elements such as sports and competitions, such as multi-person competitions, competing for the number of bubbles and speed, etc., which is more interesting and the exercise is more lasting.

[0007] Preferably, the first limit assembly includes a horizontal guide wheel and a first traction rope; the horizontal guide wheel is horizontally mounted on the base, the two ends of the first traction rope are respectively connected to the two foot pedals in a one-to-one correspondence, and the middle of the first traction rope passes around the horizontal guide wheel, and the two foot pedals alternately swing up and down, thereby causing the first traction rope to reciprocate around the horizontal guide wheel. Since the horizontal guide wheel and the first traction rope are both close to the front end of the foot pedal, the fluctuation of the front end is the smallest, and the maximum angle between the first traction rope and the horizontal guide wheel will not be too large, so the first traction rope will not completely fall off the horizontal guide wheel.

[0008] Preferably, a bracket rotatably connected to the horizontal guide wheel is provided on the base, and the bracket is slidably connected to the base along the front-rear direction, and the horizontal guide wheel is driven to move along the front-rear direction by the bracket, thereby adjusting the tightness of the first traction rope.

[0009] Preferably, the base is provided with a fixing member, and a rotating shaft is provided on the left and right sides of the fixing member respectively, and the two pedals are rotatably connected with the two rotating shafts in a one-to-one correspondence. Each pedal is provided with a sleeve adapted to the rotating shaft, and the sleeve is sleeved on the outside of the corresponding rotating shaft, and the two are connected by a rotating rod, and a bearing, a rubber sleeve, etc. can also be added between the two to reduce friction resistance.

[0010] Preferably, the base is provided with an adjustment screw distributed along the front and back, and one end of the adjustment screw is connected to the bracket by a thread; the base is provided with a slide groove along the front and back direction, the bracket is located in the slide groove, and the lower end of the central axis between the bracket and the horizontal guide wheel passes through the strip-shaped movable hole of the base; the other end of the adjustment screw is in contact with the fixing piece, and the adjustment screw is rotated to drive the bracket and the horizontal guide wheel to slide in the slide groove. The adjustment screw is rotated to make one end of the adjustment screw nut press against the fixing piece, and the reaction force is used to push the bracket to slide backward. The greater the sliding distance, the tighter the first traction rope is pulled. On the contrary, the looser the first traction rope is, the adjustment is made according to the actual situation.

[0011] Preferably, a second limit assembly is provided on the base to limit the maximum height to which the two foot pedals can swing upward. The second limit assembly includes a vertical guide wheel and a second traction rope; the vertical guide wheel is longitudinally rotatably mounted on the base, the two ends of the second traction rope are respectively fixedly connected to the two foot pedals, and the middle part of the second traction rope passes around the vertical guide wheel, and the two foot pedals alternately swing up and down, thereby causing the second traction rope to reciprocate around the horizontal guide wheel. There are two vertical guide wheels, which are rotatably connected to the left and right sides of the base respectively, and the middle part of the second traction rope passes under the two vertical guide wheels in sequence. Due to the length limitation of the second traction rope, when one foot pedal is at the lowest point, the second traction rope limits the highest point of the other foot pedal to swing upward, thereby avoiding problems such as the base tipping forward or falling sideways due to excessive upward swinging, thereby improving safety.

[0012] Preferably, a fixing rod extending upward is provided in the middle of the front part of the base, and a handle is provided at the upper end of the fixing rod. When the user steps on the pedals with both feet, he / she holds the handle with both hands to maintain balance.

In addition, after the same device is connected by a certain APP, another APP cannot be connected to avoid usage conflicts. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.

[0020] like Figure 1 As shown, this embodiment provides a bubble machine, including a base 1, a foot pedal 2, a telescopic cylinder 3, an electric bubble machine 4 and a sensor 5. There are two foot pedals 2, and the front ends of the two foot pedals 2 are respectively hinged to the left and right sides of the base 1. A telescopic cylinder 3 is provided between each foot pedal 2 and the base 1, and each telescopic cylinder 3 is tilted upward and backward. The base 1 is provided with a first limit assembly that enables the two foot pedals 2 to be linked. By pressing down any one of the foot pedals 2 and retracting the telescopic rod of the corresponding telescopic cylinder 3, the other foot pedal 2 is synchronously swung upward around the hinge point under the elastic force of the corresponding telescopic cylinder 3. The specific structure of the first limit assembly is as follows:

[0021] like Figure 1 and Figure 2As shown, the first limit assembly includes a horizontal guide wheel 6 and a first traction rope 7; the horizontal guide wheel 6 is horizontally mounted on the base 1, and the two ends of the first traction rope 7 are respectively connected to the two foot pedals 2 in a one-to-one correspondence, and the middle part of the first traction rope 7 passes around the horizontal guide wheel 6, and swings up and down alternately through the two foot pedals 2, so that the first traction rope 7 reciprocates around the horizontal guide wheel 6. Since the horizontal guide wheel 6 and the first traction rope 7 are both close to the front end of the foot pedal 2, the ups and downs of the front end are the smallest, and the maximum angle between the first traction rope 7 and the horizontal guide wheel 6 is not too large, so the first traction rope 7 will not completely fall off from the horizontal guide wheel 6. A bracket 21 rotatably connected to the horizontal guide wheel 6 is provided on the base 1, and the bracket 21 is slidably connected to the base 1 along the front-back direction, and the horizontal guide wheel 6 is driven to move along the front-back direction through the bracket 21, so as to adjust the tightness of the first traction rope 7. A fixing member 8 is provided on the base 1, and a rotating shaft 9 is provided on the left and right sides of the fixing member 8, respectively, and the two foot pedals 2 are rotatably connected to the two rotating shafts 9 in a one-to-one correspondence. Each pedal 2 is provided with a sleeve 10 adapted to the rotating shaft 9. The sleeve 10 is sleeved on the outside of the corresponding rotating shaft 9. The two form a rotating rod connection. Bearings, rubber sleeves, etc. can also be added between the two to reduce friction resistance. A treading piece 11 with a groove can be set on the top of the pedal 2. The treading piece 11 can be made of plastic. Anti-skid protrusions or anti-skid patterns are set in its groove. When the shoes step on the groove, the anti-skid effect is better. The base 1 is provided with an adjustment screw 12 distributed along the front and back. One end of the adjustment screw 12 is connected to the bracket 21 through a thread. The base 1 is provided with a slide groove 13 along the front and back direction. The bracket 21 is located in the slide groove 13, and the lower end of the central axis 14 between the bracket 21 and the horizontal guide wheel 6 passes through the strip-shaped movable hole of the base 1. Nuts are provided at both ends of the central axis 14 to prevent the central axis 14 from moving axially. The other end of the adjustment screw 12 contacts the fixing member 8. By rotating the adjustment screw 12, the bracket 21 and the horizontal guide wheel 6 are driven to slide in the slide groove 13. The adjusting screw 12 is rotated to make one end of the adjusting screw 12 nut press against the fixing member 8, and the bracket 21 is pushed to slide backward by the reaction force. The larger the sliding distance, the tighter the first traction rope 7 is pulled. On the contrary, the looser the first traction rope 7 is, the adjustment is made according to the actual situation.

[0022] In addition, if Figure 1 and Figure 2As shown, in order to further limit the ups and downs of the two foot pedals 2, the base 1 in this embodiment is provided with a second limit assembly for limiting the maximum height of the two foot pedals 2 to swing upward. The second limit assembly includes a vertical guide wheel 15 and a second traction rope 16; the vertical guide wheel 15 is longitudinally rotatably mounted on the base 1, the two ends of the second traction rope 16 are respectively fixedly connected to the two foot pedals 2, and the middle part of the second traction rope 16 bypasses the vertical guide wheel 15, and swings up and down alternately through the two foot pedals 2, thereby causing the second traction rope 16 to reciprocate around the horizontal guide wheel 6. There are two vertical guide wheels 15, which are respectively rotatably connected to the left and right sides of the base 1, and the middle part of the second traction rope 16 passes through the bottom of the two vertical guide wheels 15 in sequence. Due to the length limitation of the second traction rope 16, when one foot pedal 2 is at the lowest point, the second traction rope 16 limits the highest point of the other foot pedal 2 to swing upward, thereby avoiding the problem of the base 1 tipping forward or falling sideways due to the excessive upward swing, thereby improving safety.

[0023] In order to combine the motion and the bubble machine, one of the two foot pedals 2 in this embodiment is provided with a sensing element 17 adapted to the sensor 5. The bubble machine and the sensor 5 are both mounted on the base 1, and the detection end of the sensor 5 faces the direction where the sensing element 17 is located; the bubble machine and the sensor 5 are electrically connected, and the sensing element 17 swings up and down with the corresponding foot pedal 2, so that the sensing element 17 reciprocates through the detection end of the sensor 5 to control the bubble speed of the bubble machine. Furthermore, an equipment box 18 is provided in front of the base 1, and a control circuit board, a networking module and a power supply are provided in the equipment box 18. The control circuit board, the networking module and the power supply are not drawn in the accompanying drawings, and are all hidden in the equipment box 18. The electric bubble machine 4 is located above the equipment box 18, and the spraying direction of the electric bubble machine 4 faces forward; the control circuit board is electrically connected to the electric bubble machine 4, the sensor 5, the networking module and the power supply respectively. The user downloads a dedicated APP on his mobile phone, which is wirelessly connected to the control circuit board through the networking module. The control circuit board feeds back the collected parameters to the APP, which automatically generates parameters such as exercise time, speed, and energy consumption according to the set sequence. The user can see the exercise data at a glance. In addition, when the same device is connected by a certain APP, other APPs cannot be connected to avoid conflicts of use.

[0024] This embodiment provides a method for using a bubble machine, which is as follows:

The amplitude of the up and down swinging is fed back to the control circuit board by the sensor 5. The control circuit board controls the bubble machine's bubble speed according to the amplitude parameter, and the two are proportional.

[0028] S4. The control circuit board feeds data back to the APP through the networking template, and the user can check the exercise records at any time.

[0029] S5. After use, the APP is disconnected and the bubble machine returns to standby mode for next use.

[0030] In actual use, multiple people use the corresponding bubble machine at the same time, forming friendly competition with each other, comparing the number and speed of bubbles, etc., which is more interesting and the exercise is more lasting.

[0031] In this embodiment, the telescopic cylinder 3 is a spring telescopic cylinder 3, and the sensor 5 is a Hall sensor 5, which is used to collect the moving speed of the sensing member 17. The sensing member 17 is a metal plate, which will be captured by the Hall sensor 5 when passing through the detection end of the Hall sensor 5, so as to measure its speed.
