Description

Technical Field

[0001] This invention relates to the field of household appliances, and more specifically, to a pumping device and a pumping equipment having the same. Background Technology

[0002] Rice cookers often experience overflowing issues when using them. Overflowing significantly impacts the user experience, not only polluting the kitchen environment but also causing food waste.

[0003] Currently, pumping air into the inner pot is one of the commonly used methods to prevent overflow. This creates an airflow vortex in the inner pot, generating a significant pressure and temperature difference between the food being cooked, which then bursts the air bubbles.

[0004] Because using an air pump to break bubbles requires an air tube to guide the gas, the existing pumping methods have the following problems:

[0005] Existing air tubes are generally made of silicone tubing, but silicone tubing is relatively soft and is prone to kinking during use, which can affect the operation of the air pump.

[0006] After prolonged use, the air hose may come loose due to the force of pumping or suction.

[0007] The need to install clips to control the direction of the air pipes makes the structure of the air pump device complex. Summary of the Invention

[0008] The main objective of this invention is to provide a pumping device and a pumping equipment having the same, so as to solve the problem that the air pipe of the pumping device in the prior art is easily kinked.

[0009] To achieve the above objectives, according to one aspect of the present invention, a gas pumping device is provided, comprising: a channel support having a gas channel having an inlet and a pumping port for communicating with a cavity of an inner pot; and a pump support connected to the channel support for mounting a pump to drive gas flow within the gas channel by communicating the cavity of the pump with the gas channel.

[0010] Furthermore, the channel support includes: an upper channel support with an upper vent groove; and a lower channel support with a lower vent groove. The upper and lower channel supports are detachably connected, and the upper and lower vent grooves are joined to form a gas channel.

[0011] Furthermore, the upper channel support is provided with a positioning groove, and the lower channel support is provided with a positioning post. The positioning post is inserted into the positioning groove so as to position the upper channel support and the lower channel support through the cooperation between the positioning post and the positioning groove.

[0012] Furthermore, the air pump bracket includes: a connecting plate, which is connected to the channel bracket; and a sleeve, which is disposed on the connecting plate and is used to fit onto the air pump for installation. The connecting plate is provided with mounting holes for fasteners to pass through, so that the air pump bracket can be connected to the fixed foundation by fasteners passing through the mounting holes.

[0013] Furthermore, the air pumping device also includes a buffer ring, which is disposed on the inner side of the sleeve and is used to be fitted onto the air pump to clamp between the sleeve and the air pump.

[0014] Furthermore, the gas channel includes a first channel section and a second channel section, and the pumping device further includes: a first seal, which is disposed on the channel support; the first seal includes a first gas path and a second gas path, the first gas path being connected to the first channel section and the second gas path being connected to the second channel section; an air inlet is disposed on the first channel section and a pumping port is disposed on the second channel section; wherein, the air pump includes a first connecting part and a second connecting part, the first connecting part being connected to the first gas path and the second connecting part being connected to the second gas path.

[0015] Furthermore, the first sealing element includes a first tube body and a second tube body. The cavity of the first tube body is at least a portion of the first air passage, and the cavity of the second tube body is at least a portion of the second air passage. Both the first tube body and the second tube body are provided with first retaining ribs, and the channel bracket is provided with first positioning grooves that cooperate with each of the first retaining ribs, so as to position the first sealing element through the cooperation between the first retaining ribs and the corresponding first positioning grooves.

[0016] Furthermore, the air pumping device also includes: a second seal, which is disposed at the air inlet; the second seal is provided with a second retaining rib, and the channel bracket is provided with a second positioning groove that mates with the second retaining rib, so as to position the second seal through the cooperation between the second retaining rib and the second positioning groove; and / or, a third seal, which is disposed at the air pumping port; the third seal is provided with a third retaining rib, and the channel bracket is provided with a third positioning groove that mates with the third retaining rib, so as to position the third seal through the cooperation between the third retaining rib and the third positioning groove.

[0017] Furthermore, the gas channel includes a first channel segment and a second channel segment, and the channel support includes a first strip segment and a second strip segment. The first channel segment is disposed on the first strip segment, and the second channel segment is disposed on the second strip segment. Both the first strip segment and the second strip segment are curved, with the first channel segment extending along the first strip segment and the second channel segment extending along the second strip segment.

[0018] According to another aspect of the present invention, a pumping device is provided, which includes the above-described pumping apparatus and an air pump mounted on the pumping apparatus.

Furthermore, since the use of soft silicone tubing as the air pipe is avoided, the problems of easy kinking of the air pipe, easy detachment of the connection end, and the complexity of the air pumping device structure caused by the need to set a buckle to control the direction of the air pipe caused by the use of soft silicone tubing are also eliminated. It can be seen that this air pumping device can solve the problem of easy kinking of the air pipe in the prior art air pumping device. Attached Figure Description

[0042] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0043] This invention provides a pumping device; please refer to [the relevant documentation]. Figures 1 to 7 The air pumping device includes a channel support 10 and an air pump support 20. The channel support 10 is provided with a gas channel 13, which has an air inlet 135 and a pumping port 136 for communicating with the cavity of the inner pot. The air pump support 20 is connected to the channel support 10 and is used to install an air pump 30 to drive the gas flow in the gas channel 13 by communicating the cavity of the air pump 30 with the gas channel 13.

[0044] In the air pumping device of the present invention, the air pumping device includes a channel support 10 and an air pump support 20 for mounting an air pump 30. The air pump support 20 is connected to the channel support 10, and a gas channel 13 with an air inlet 135 and a pumping port 136 for communicating with the cavity of the inner pot is provided on the channel support 10. The gas flow in the gas channel 13 is driven by communicating the air pump 30 mounted on the air pump support 20 with the gas channel 13. Since the air pumping device of the present invention sets the gas channel 13 on the channel support 10, the gas channel 13 has a stable structure, will not be kinked or fall off, and does not require a direction control component. Furthermore, since the use of soft silicone tubing as the air pipe is avoided, the problems of easy kinking of the air pipe, easy detachment of the connection end, and the complexity of the air pumping device structure caused by the need to set a buckle to control the direction of the air pipe caused by the use of soft silicone tubing are also eliminated. It can be seen that the air pumping device can solve the problem of easy kinking of the air pipe in the prior art air pumping device.

[0045] Optionally, both the channel bracket 10 and the air pump bracket 20 are made of rigid materials.

The positioning post 121 is inserted into the positioning groove 112 so that the upper channel bracket 11 and the lower channel bracket 12 are positioned by the cooperation between the positioning post 121 and the positioning groove 112, thereby realizing the detachable connection between the upper channel bracket 11 and the lower channel bracket 12.

[0048] Alternatively, the positioning groove can be set on the lower channel bracket 12, the positioning post can be set on the upper channel bracket 11, and the positioning post set on the upper channel bracket 11 can be inserted into the positioning groove on the lower channel bracket 12.
