Description

Technical Field

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

[0002] With the continuous development of technology, devices for making soda (commonly also called sparkling water machines) have also been widely used in daily life. Ordinary people can make soda at home for easy drinking, which improves people's living standards and meets people's requirements for healthy eating.

[0003] Figure 1 The invention relates to an automatic seasoning device, comprising a frame 1 and a seasoning box 11, a seasoning box 12, an air pump 13 and an air pump 14 arranged on the frame 1. The seasoning box 11 and the air pump 13 are connected by a seasoning air path 15, and the seasoning box 12 and the air pump 14 are connected by a seasoning air path 2 16. The air pumps 13 and 14 squeeze out the seasonings in the corresponding seasoning boxes as needed to automatically add seasonings for seasoning.

[0004] Although the above-mentioned automatic seasoning device can adjust the taste during use, air pump one and air pump two only control the extrusion of seasoning in one seasoning box. When the seasoning in the other seasoning box needs to be extruded, air pump one needs to be switched to air pump two, resulting in air pump two being unused when air pump one is used, and air pump one being unused when air pump two is used. When making a single flavor, there is always one air pump that is unused, resulting in low air pump utilization, and the installation of two air pumps increases the cost of the sparkling water machine. Utility Model Content

[0005] The purpose to be achieved by the utility model is to provide a bubble water machine, solve the problems of high cost and low utilization rate of the air pump, reduce the cost of the bubble water machine and improve the utilization rate of the air pump.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a bubble water machine, including a body and a bubble water generating device, a seasoning box, and an extrusion assembly arranged on the body, the bubble water generating device is used to generate bubble water, the seasoning box has a plurality of seasoning chambers for holding seasonings, the extrusion assembly squeezes out the seasonings in the seasoning chamber to season the bubble water, the extrusion assembly includes an air pump and a regulating valve, the regulating valve has an air inlet and a plurality of air outlets, the air inlet is connected to the air pump, and the air outlets are respectively connected one-to-one with the seasoning chambers, and the regulating valve is controlled to connect or disconnect the air outlets and the air inlet.

[0007] After adopting the above technical solution, the utility model has the following advantages: when using the bubble water machine, the air inlet is connected or disconnected with one air outlet, or the air inlet is connected or disconnected with two or more air outlets through the control of the regulating valve. Specifically, when there is no need to adjust the taste of the bubble water, the air inlet on the regulating valve is closed, so that the air pressure in the air pump cannot act on the seasoning chamber, and the seasoning in the seasoning box cannot be squeezed out; when only one flavor of bubble water needs to be adjusted, the regulating valve closes the remaining air outlets, so that the air inlet is connected to the air outlet of the corresponding flavor, and the air pump works, and the air pressure acts on the flavoring chamber. When the air pump is used, the flavoring in the seasoning box is squeezed out to make sparkling water of the corresponding flavor; if it is necessary to make sparkling water of multiple flavors at the same time, the regulating valve is controlled so that the air inlet is connected to multiple air outlets, so that the air pressure generated by one air pump acts on multiple seasoning boxes at the same time, and the flavoring in multiple seasoning boxes is squeezed out to make sparkling water of the corresponding flavor; the above-mentioned control can be achieved by connecting an air pump to the regulating valve, which reduces the cost of the sparkling water machine, and an air pump also facilitates the layout of components inside the sparkling water machine, improves the space utilization inside the machine body, and facilitates the miniaturization of the sparkling water machine.

[0008] Furthermore, the regulating valve includes a valve body and a valve core, the valve body has a valve cavity, the air inlet and the air outlet are both arranged at the rear end of the valve body and pass through the valve body forward to communicate with the valve cavity, the valve core is arranged in the valve cavity, and there is a connecting gap between the rear end face of the valve core and the rear end face of the valve cavity to connect the air inlet and the air outlet, and the valve core rotates relative to the valve body to close or open the air inlet or the air outlet.

[0009] The above-mentioned technical solution is used to control the connection or disconnection between the air inlet and the air outlet by rotating the valve core so that the rear end face of the valve core closes the air inlet or the air outlet at the rear end face of the valve cavity. Specifically, when the valve core does not close the air inlet and the air outlet, the action of the air pump acts on multiple air outlets through the connecting gap between the rear end face of the valve core and the rear end face of the valve cavity, thereby simultaneously producing multiple flavors of sparkling water; when only a single flavor of sparkling water is produced, the rear end face of the valve core closes the other air outlets, so that the air inlet is connected to the corresponding single air outlet through the connecting gap; and when no flavor adjustment is required, the rear end face of the valve core closes the air inlet so that air pressure cannot act on the air outlet. The connecting gap between the rear end face of the valve core and the rear end face of the valve cavity facilitates the connection or disconnection between the air inlet and the air outlet, and between the air outlets, facilitating the production of sparkling water of a single flavor or the simultaneous production of sparkling water of multiple flavors.

[0010] Furthermore, the rear end face of the valve core is provided with a seal that protrudes toward the rear end face of the valve cavity. The seal rotates with the valve core, and the air inlet and the air outlet are distributed on the rotation path of the seal. The seal presses against the air inlet to close the air inlet or presses against the air outlet to close the air outlet.

[0011] By adopting the above-mentioned technical solution, the air inlet and the air outlet are distributed on the rotation path of the seal, and the valve core is rotated, and the seal rotates with the valve core, so that the seal switches to block the air inlet or different air outlets, and the seal abuts the rear end face of the valve cavity to avoid the position of the air inlet and the air outlet, which is convenient for the production of sparkling water with different flavors. The air inlet or the air outlet is closed by the seal to improve the sealing performance during closure and avoid the presence of gaps that affect the sealing effect. The seal is made of flexible material, and the rotation operation has a tactile feel but no noise, which can improve the user experience.

[0012] Furthermore, the rear end face of the valve cavity is provided with a first annular rib at the edge of the air inlet, the seal rotates with the valve core and passes over the first annular rib to close the air inlet, and the first annular rib squeezes the end face of the seal to form a sealing structure; and / or, the rear end face of the valve cavity is provided with a second annular rib at the edge of the air outlet, the seal rotates with the valve core and passes over the second annular rib to close the air outlet, and the second annular rib squeezes the end face of the seal to form a sealing structure.

[0013] By adopting the above-mentioned technical solution, when the seal is sealed at the air inlet, the first annular rib is squeezed on the end face of the seal, so that the first annular rib and the seal form a sealing structure, thereby improving the sealing effect of the seal at the air inlet, and avoiding air leakage due to a gap between the air inlet and the seal after the air inlet is closed; or the second annular rib is squeezed on the end face of the seal, so that a sealing structure is formed between the second annular rib and the end face of the seal, thereby improving the sealing effect of the seal when closing the air outlet, and avoiding air leakage due to a gap between the seal and the air outlet.

[0014] Furthermore, one of the rear end face of the valve cavity and the rear end face of the valve core is provided with a positioning shaft, and the other is provided with a positioning shaft hole. The positioning shaft hole cooperates with the positioning shaft, the seal moves around the positioning shaft, and the air inlet and the air outlet are distributed around the positioning shaft.

[0015] By adopting the above-mentioned technical solution, after the valve core is inserted into the valve cavity, the seal moves around the positioning shaft, and at the same time the air inlet and the air outlet are distributed around the positioning shaft. The positioning shaft cooperates with the positioning shaft hole, so that the seal closes the air inlet or the air outlet when it moves around the positioning shaft, which facilitates the switching of the air inlet and the air outlet closure, and at the same time improves the stability of the connection between the valve core and the valve body. After long-term use, the seal still accurately closes the air inlet and the air outlet.

[0016] Furthermore, the rear end face of the valve core is provided with a protruding supporting rib, which presses against the rear end face of the valve cavity to axially position the valve core; and / or, the inner side surface of the valve cavity is provided with a first positioning step, and the outer periphery of the valve core is provided with a second positioning step, which presses against the first positioning step to axially position the valve core.

[0017] By adopting the above-mentioned technical solution, the supporting rib abuts against the rear end face of the valve body, so that the valve core and the valve body are positioned axially, the stability of the connection between the valve body and the valve core is improved, and the height of the connecting gap is ensured; the first positioning step abuts against the second positioning step, positioning the valve core axially, and avoiding shaking between the valve core and the valve cavity, thereby improving the stability of the valve core and the valve cavity, and also ensuring the height of the connecting gap.

[0018] Furthermore, the rear end face of the valve cavity has a first area, which is located between the air inlet and the air outlet or between the two air outlets. The sealing member stays in the first area so that the air inlet and the air outlet are both in an open state.

[0019] By adopting the above-mentioned technical solution, when it is necessary to make sparkling water of different flavors at the same time, the valve core is rotated so that the valve core drives the seal to rotate and abut against the first area, so that the seal abuts between the air inlet and the air outlet or abuts between the two air outlets, so that the air inlet and multiple air outlets are in an open state at the same time, which is convenient for making sparkling water of different flavors at the same time.

[0020] Furthermore, the front end of the valve core is provided with an adjusting knob for driving the valve core to rotate. The adjusting knob is axially positioned relative to the valve body and can rotate relative to the valve body. The adjusting knob is exposed on the outer surface of the body.

[0021] By adopting the above-mentioned technical solution, the adjusting knob installed at the front end of the valve core is exposed on the outer surface of the body. When it is necessary to make sparkling water of different flavors, the valve core is driven to rotate by the adjusting knob, thereby improving the operational convenience when the valve core rotates.

[0022] Furthermore, a sealing ring is provided between the outer peripheral side surface of the valve core and the inner side surface of the valve cavity.

[0023] By adopting the above-mentioned technical solution, the outer peripheral side of the valve core and the inner side of the valve cavity are sealed by a sealing ring to prevent the gas in the connecting gap from leaking through the outer peripheral side of the valve core and the inner side of the valve cavity.

[0024] Furthermore, an air inlet connector and an air outlet connector are provided at the rear end of the regulating valve, and the air inlet connector and the air outlet connector extend backward, the air inlet passes through the air inlet connector, and the air outlet passes through the air outlet connector, and the two ends of the air inlet pipe are respectively connected to the air inlet connector and the air pump, and the two ends of the air outlet pipe are respectively connected to the air outlet connector and the seasoning box; and / or, the body includes an outer shell, and a protruding connecting portion is provided on the outer side of the regulating valve, and a fastener passes through the connecting portion and is connected to the outer shell to fix the regulating valve.

[0025] With the aforementioned technical solution, when the inlet pipe is connected to the air inlet, it is connected to the inlet joint, facilitating the connection between the inlet pipe and the air inlet; when the outlet pipe is connected to the air outlet, it is connected to the outlet joint, facilitating the connection between the outlet pipe and the outlet joint; this improves the stability of the connections between the inlet pipe and the air inlet, and between the outlet pipe and the air outlet, and reduces the possibility of the connections between the inlet pipe and the air inlet, and between the outlet pipe and the air outlet becoming detached. After the regulating valve is installed on the machine body, the front end of the regulating valve protrudes from the housing, and the protruding connection portion on the outer side of the regulating valve is connected to the housing via fasteners, thereby securing the regulating valve to the housing, improving the stability of the regulating valve after installation, and preventing the regulating valve from becoming loose relative to the housing and affecting its use.

[0040] The following specific embodiments are used to describe the technical solution of the present invention in detail. The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0041] like Figure 2 As shown, the utility model provides a bubble water machine, including a body 2 and a bubble water generating device 21, a seasoning box, and an extrusion component 4 arranged on the body 2. The bubble water generating device 21 is used to generate bubble water. The seasoning box has a plurality of seasoning cavities 3 for holding seasonings. The extrusion component 4 squeezes out the seasoning in the seasoning cavity 3 to flavor the bubble water.

[0042] In this embodiment, if Figure 2 and Figure 3 As shown, the extrusion assembly 4 includes an air pump 41 and a regulating valve 42. The regulating valve 42 has an air inlet 4212 and multiple air outlets 4213. Specifically, there are two air outlets 4213. The air inlet 4212 is connected to the air pump 41 through an air inlet pipe 411. The number of flavoring chambers 3 is the same as the number of air outlets 4213 and they correspond one to one and are connected. The air outlet 4213 is connected to the flavoring chamber 3 through an air outlet pipe 211. Figure 3 、 Figure 4As shown, the regulating valve 42 includes a valve body 421 and a valve core 422. The valve body 421 has a valve cavity 4211. An air inlet 4212 and two air outlets 4213 are both located at the rear end of the valve body 421. The air inlet 4212 and the air outlets 4213 both extend forward through the valve body 421 and communicate with the valve cavity 4211. During installation, the valve core 422 is installed within the valve cavity 4211 and is rotatable relative to the valve cavity 4211. The rear end surface of the valve core 422 is provided with a seal 4221 that protrudes toward the rear end surface of the valve cavity 4211. The seal 4221 rotates with the valve core 422. The air inlet 4212 and the two air outlets 4213 are circumferentially distributed and are located along the rotation path of the seal 4221. The seal 4221 can be made of a material with a certain degree of elastic deformation, such as rubber.

[0043] When making specific adjustments, such as Figure 5-1 and Figure 5-2 As shown, the valve core 422 is rotated, thereby driving the sealing member 4221 to rotate along with the valve core 422, as shown in FIG. Figure 5-2 As shown, when the bubble water machine is not needed or flavored bubble water is not needed, the seal 4221 rotates with the valve core 422 and abuts against the air inlet 4212, thereby closing the air inlet 4212; Figure 5-1 As shown, when a single flavor of sparkling water is to be prepared, the valve core 422 and the sealing member 4221 are rotated so that the sealing member 4221 contacts the air outlet 4213, thereby connecting the air inlet 4212 with the unsealed air outlet 4213. The unsealed air outlet 4213 is the air outlet 4213 connected to the flavoring chamber 3 of the flavor to be prepared, so that the air pump 41 acts on the corresponding flavoring box through the connected air inlet 4212 and air outlet 4213. Figure 6-1 and Figure 6-2 As shown, in addition, the rear end surface of the valve cavity 4211 has a first area 4219, and the first area 4219 is located between the air inlet 4212 and the air outlet 4213 or between the two air outlets 4213. When the sealing member 4221 rotates with the valve core 422 and stays in the first area 4219, the air inlet 4212 and the two air outlets 4213 are both in an open state. At this time, the air pump 41 can act on the two seasoning boxes, so that the bubble water machine can produce two flavors of bubble water at the same time. Figure 2 As shown, the production of the above-mentioned flavored sparkling water is controlled by only one air pump 41 and one regulating valve 42, which improves the utilization rate of the air pump 41 and reduces the cost of installing multiple air pumps 41. At the same time, only one air pump 41 is installed in the body 2, which facilitates the layout of components in the internal space of the body 2 and miniaturizes the sparkling water machine.

[0044] In this embodiment, if Figure 3 and Figure 7As shown, in order to facilitate the connection between the air inlet 4212 and the air outlet 4213, a connecting gap 4227 is provided between the rear end face of the valve core 422 and the rear end face of the valve cavity 4211 for connecting the air inlet 4212 and the air outlet 4213. When the valve core 422 is inserted into the valve cavity 4211, the air inlet 4212 and the air outlet 4213 are connected through the reserved connecting gap 4227, thereby improving the connection between the air inlet 4212 and the air outlet 4213.

[0045] In another embodiment, Figure 5-2 As shown, in order to improve the sealing performance when the air outlet 4213 is closed, a first annular rib 4218 is provided on the back of the valve cavity 4211. The first annular rib 4218 is located at the edge of the air inlet 4212. When the seal 4221 rotates with the valve core 422, the seal 4221 passes over the first annular rib 4218 and closes the air inlet 4212. The first annular rib 4218 squeezes the end face of the seal 4221 to form a sealing structure, thereby sealing any gap between the seal 4221 and the air inlet 4212, improving the sealing performance between the seal 4221 and the air inlet 4212, and avoiding air leakage caused by the gap between the seal 4221 and the air inlet 4212. At the same time, as Figure 7 As shown, in order to improve the sealing at the air outlet 4213, the rear end face of the valve cavity 4211 is provided with a second annular rib 4217, and the second annular rib 4217 is located at the edge of the air outlet 4213. The seal 4221 rotates with the valve core 422 and passes over the second annular rib 4217 to close the air outlet 4213. When the seal 4221 closes the air outlet 4213, the second annular rib 4217 squeezes the end face of the seal 4221 and forms a sealing structure together with the seal 4221, thereby improving the sealing between the seal 4221 and the air outlet 4213 and avoiding air leakage due to a gap between the seal 4221 and the air outlet 4213.

[0046] In order to improve the installation stability of the valve chamber 4211 and the valve core 422, as shown in FIG. Figure 7 As shown, the rear end face of the valve cavity 4211 is provided with a positioning shaft 4216, and the rear end face of the valve core 422 is provided with a positioning shaft hole 4222. When the valve core 422 is arranged in the valve cavity 4211, the positioning shaft 4216 cooperates with the positioning shaft hole 4222, thereby axially positioning the valve core 422 and the valve cavity 4211 to improve the stability of the valve core 422 and the valve cavity 4211 after installation.

[0047] In this embodiment, if Figures 4 to 7As shown, the seal 4221 moves around the positioning shaft 4216, and the air inlet 4212 and the air outlet 4213 are distributed around the positioning shaft 4216, so that the rotation axis of the seal 4221 coincides with the axis of the circumferential distribution of the air inlet 4212 and the air outlet 4213, which facilitates the closing of the air inlet 4212 or the air outlet 4213 during the rotation of the seal 4221.

[0048] In another embodiment, the positioning shaft hole 4222 is provided on the rear end face of the valve cavity 4211 , and the positioning shaft 4216 is provided on the rear end face of the valve core 422 . When the valve core 422 is connected to the valve cavity 4211 , the positioning shaft 4216 is fitted and inserted into the positioning shaft hole 4222 .

[0049] In order to improve the stability of the connection between the valve core 422 and the valve cavity 4211, as shown in FIG. Figure 7 As shown, the rear end face of the valve core 422 is provided with a protruding support rib 4223, which is located inside the rotation path of the sealing member 4221. As the valve core 422 and the valve cavity 4211 are plugged in, the support rib 4223 gradually approaches the rear end face of the valve cavity 4211 until the support rib 4223 abuts against the rear end face of the valve cavity 4211, thereby positioning the valve core 422 in the axial direction. The support rib 4223 does not contact the air inlet 4212 and the air outlet 4213. In another embodiment, as Figure 8 As shown, a first positioning step 4224 is provided on the inner side of the valve cavity 4211, and a second positioning step 4225 is provided on the outer periphery of the valve core 422. The second positioning step 4225 abuts against the first positioning step 4224, thereby axially positioning the valve core 422. The abutment between the supporting rib 4223 and the rear end surface of the valve cavity 4211, or the abutment between the first positioning step 4224 and the second positioning step 4225, positions the valve core 422 in the axial direction, thereby improving the stability of the valve core 422 after being connected to the valve cavity 4211.

[0050] To facilitate the adjustment of the valve core 422, as Figure 3 and Figure 4 As shown, the front end of the valve core 422 is provided with an adjusting knob 423 for driving the valve core 422 to rotate. The adjusting knob 423 is axially positioned relative to the valve body 421 and can rotate relative to the valve body 421. The adjusting knob 423 is exposed on the outer surface of the body 2. When it is necessary to adjust the taste of the bubble water, the adjusting knob 423 is rotated to drive the valve core 422 to rotate relative to the valve body 421, thereby adjusting the two air outlets 4213.

[0051] In order to improve the sealing between the valve core 422 and the valve cavity 4211, as shown in FIG. Figure 8As shown, a sealing ring 4226 is provided between the outer peripheral side of the valve core 422 and the inner side of the valve cavity 4211 to improve the sealing performance of the valve core 422 and prevent the air pressure entering the connecting gap 4227 from leaking between the outer peripheral side of the valve core 422 and the inner side of the valve cavity 4211.

[0052] In another embodiment, Figure 3 and Figure 4 As shown, in order to facilitate the connection between the air inlet 4212 and the air pump 41, and the air outlet 4213 and the seasoning box, the rear end of the regulating valve 42 is provided with an air inlet joint 4214 and an air outlet joint 4215. After one end of the air inlet pipe 411 is connected to the air pump 41, the other end is connected to the air inlet joint 4214. Through the installation of the air inlet joint 4214, when the air inlet pipe 411 is connected to the air inlet 4212, the air inlet joint 4214 extends backward so that the connection end of the air inlet 4212 and the air inlet pipe 411 is different from the rear end surface of the valve body 421, which reserves a certain space for the installation of the air inlet pipe 411, making it convenient for the air inlet pipe 411 to connect with the air inlet 421. 2 connection operation, the air inlet pipe 411 is sleeved on the air inlet joint 4214 or the air inlet joint 4214 is sleeved on the air inlet pipe 411, the connection between the air outlet 4213 and the seasoning box is connected through the air outlet pipe 211, and the rear end of the regulating valve 42 is provided with an air outlet joint 4215, the air outlet 4213 is provided in the air outlet joint 4215, and the air outlet joint 4215 extends backward, so that the connection position of the air outlet joint 4215 and the air outlet pipe 211 is different from the rear end surface of the valve body 421, thereby reserving an installation space for the connection between the air outlet joint 4215 and the air outlet pipe 211, which is convenient for operating the connection between the air outlet pipe 211 and the air outlet joint 4215.

[0053] In order to improve the stability of the regulating valve 42 after installation, Figure 4 and Figure 9 As described above, the body 2 includes an outer shell, and a protruding connecting portion is provided on the outer side of the regulating valve 42. The connecting portion and the casing are fastened together by fasteners 424, thereby fastening the regulating valve 42 to the outer shell, thereby improving the stability of the regulating valve 42.

[0054] In addition to the above-mentioned preferred embodiments, the present invention has other implementation methods. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection requested by the present invention.
