Description

Technical Field

[0001] The present application relates to the technical field of air pumps, and further to a dual-purpose air pump for pumping and charging and an air pump assembly. Background Art

[0002] An air pump is a device that removes air from a closed space or adds air to a closed space. It is often used as an essential tool for efficient inflation and exhaust.

[0003] At present, there are many items that need to be inflated or deflated in production and life, such as inflatable cushions and compression bags. If they are equipped with an inflation pump and a deflating pump respectively, the user cost is high; therefore, in response to user needs, machines with dual-purpose functions of inflation and deflating have emerged. In the related art, most of the inflatable and deflating machines are connected to the inflation end and the deflating end of the air pump by setting an air inlet pipe and an air deflating pipe respectively. When in use, according to the specific inflation and deflating needs, the corresponding passage selection module is used to select the air inlet pipe or the air deflating pipe to be connected to the inflation port or the air deflating port of the corresponding product to achieve the corresponding inflation or deflating action.

[0004] However, most of these inflator and pumping machines have complex structures, are difficult to produce, and have high production costs. In this regard, the inventor believes that developing a pumping and inflating air pump product with a simple structure, easy production and use, and low cost will have a profound impact on the development of the air pump industry. Utility Model Content

[0005] The purpose of the present application is to provide a dual-purpose air pump for pumping and charging and an air pump assembly, which are used to simplify the overall structure of the dual-purpose air pump for pumping and charging, reduce its production difficulty, save the company's production costs, and at the same time, improve its ease of use.

[0010] An exhaust port is provided on the side wall of the shell corresponding to the air chamber and is located in the air outlet direction of the impeller, and is used to dock with the air nozzle of the side wall of the inflatable component when the shell is inserted into the inflatable component in a forward state; an avoidance groove is provided on the side wall of the shell corresponding to the exhaust port, and the avoidance groove is used to avoid the one-way valve opening key of the inflatable component air nozzle after the exhaust port is docked with the inflatable component air nozzle;

[0011] An air intake port is arranged at one end of the shell in the length direction and is located in the air inlet direction of the impeller. It is used to connect with the air duct of the air nozzle of the inflatable component after the shell is inserted into the inflatable component in an inverted state and the side wall of the shell pushes open the one-way valve opening key of the air nozzle of the inflatable component.

At this time, positive pressure is generated at the exhaust port, and the valve plate of the one-way valve in the inflatable part is pushed to open, and air is continuously filled into the interior of the corresponding inflatable product to realize the inflation function.

[0014] In this way, the shell of the dual-purpose pump is set to be a long cylindrical structure, so that the dual-purpose pump can be inserted into the inflatable part of the inflatable product in both the forward and inverted states, so as to adapt to the opening and closing logic of the one-way valve of the inflatable part, and thus there is no need to specially set up an inflation tube, an exhaust tube and a corresponding passage selection module, and the two functions of inflation and exhaust can be realized simultaneously through only one normal air path, which effectively simplifies the overall structure of the air pump with the two functions of exhaust and inflation, and reduces its production difficulty and production cost. At the same time, the installation operation of the dual-purpose pump on the inflatable product can be completed by simply inserting the dual-purpose pump into the corresponding inflatable part in the forward or inverted state, and the inflation and exhaust operations are convenient and easy to implement, which effectively ensures the convenience of use of the dual-purpose pump. In addition, after the use of the dual-purpose air pump, it can be pulled out from the inflatable parts of the corresponding inflatable products at any time, which is convenient for maintenance and replacement, and can continue to be used for other inflatable parts, effectively reducing the user's application cost and improving its practicality; of course, it can also continue to be built into the corresponding inflatable parts for storage, which is convenient for next use and improves the user experience.

[0058] In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the specific implementation methods of the present application will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0059] In order to simplify the drawings, only the parts related to the present application are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically drawn or marked. In this article, "one" not only means "only one", but also means "more than one".

[0060] At present, outdoor inflatable products such as inflatable beds, inflatable cushions, and inflatable tents are in great demand. As an essential tool for efficient inflation and deflating, the air pump industry is developing rapidly. There are many types of air pump products on the market, such as dual-purpose air pumps with both inflation and deflation functions, and built-in air pumps that can be built into the inflatable parts of inflatable products. However, most of the dual-purpose air pumps on the market currently achieve both the functions of deflating and inflating by separately setting up an air inlet pipe and an air extraction pipe, and cooperating with corresponding passage selection modules; this type of air pump has a complex structure, is difficult to produce, has a high cost, and is inconvenient to use; in addition, for built-in air pump products, the pump body can only be fixed in the inflatable part and used in a one-to-one manner with the inflatable part. If the air pump is damaged, the inflatable part will also tend to be scrapped and cannot be used any more. The user application cost is high, and there is room for improvement.

[0061] In this regard, refer to the accompanying drawings of the specification Figures 1 to 6 In one embodiment, a dual-purpose air pump for pumping and filling is provided, which includes a long cylindrical shell 1, an impeller 2 installed in the shell 1, and an exhaust port 1211 and an air inlet 141 opened on the shell 1; wherein a wind chamber is formed inside the shell 1, and the impeller 2 is arranged in the wind chamber to rotate around its own axis. At the same time, a driving component 3 and a related circuit module 4 for driving the impeller 2 to rotate are provided in the shell 1; the exhaust port 1211 is opened at a position of the side wall of the shell 1 corresponding to the wind chamber, so that when the shell 1 is inserted into the inflatable When the inflatable part 100 is installed on the product, the air nozzle of the side wall of the inflatable part 100 is docked; at the same time, in order to avoid the one-way valve opening key 210 of the air nozzle of the inflatable part 100, the side wall of the shell 1 corresponding to the exhaust port 1211 is also provided with an avoidance groove; the air intake port 141 is opened at one end of the shell 1 in the length direction of the impeller 2, and is used to be connected with the air duct of the air nozzle of the inflatable part 100 after the inflatable part 100 is inserted into the shell 1 in an inverted state and the one-way valve opening key 210 of the air nozzle of the inflatable part 100 is pushed open by the side wall of the shell 1.

[0062] As is known to all, the side wall of the inflatable part 100 on the inflatable product is usually installed with a one-way valve 200, and the opening and closing direction of the one-way valve 200 is perpendicular to the axial direction of the inflatable part 100. A one-way valve opening key 210 is provided at one end of the one-way valve 200 close to the inflatable part 100, and the one-way valve opening key 210 extends into the inner cavity of the inflatable part 100, and the valve sheet of the one-way valve 200 extends into the inner cavity of the inflatable product and fits into the end of the air nozzle extending into the inner cavity of the inflatable product; during use, the valve sheet of the one-way valve 200 is opened by pushing the one-way valve opening key 210, so that the inner cavity space of the inflatable product is connected with the outside; when the one-way valve opening key 210 is not pushed, the one-way valve 200 is in a closed state. In actual application, the pump is inserted into the inflatable part 100 of the corresponding inflatable product in a forward state and an inverted state along the length direction of the shell 1 to respectively realize the inflation and inflation actions of the inflatable product.

[0063] Reference Figures 1 to 3 In actual application, when performing the inflation operation, the shell 1 slides relative to the inner wall of the inflatable component 100 along its own length direction, and keeps one end of the air intake port 141 facing outward, and the pump is inserted into the corresponding inflatable component 100 in a forward state until the one-way valve opening key 210 is embedded in the avoidance groove; at this time, the pump is started, and the driving component 3 drives the impeller 2 to rotate, so that the air in the environment enters the wind chamber from the air intake port 141, and is discharged from the exhaust port 1211 after being driven by the impeller 2. At this time, positive pressure is generated at the exhaust port 1211, thereby pushing the valve plate of the one-way valve 200 in the inflatable component 100 to open, and air is continuously filled into the inner cavity of the corresponding inflatable product until the entire inflation process is completed.

[0064] When performing the air extraction operation, the dual-purpose air pump is inserted into the corresponding inflatable part 100 in an inverted state, that is, the shell 1 is inserted into the inflatable part 100 along its own length direction, and one end of the air inlet 141 is kept facing inward. Since the side wall of the shell 1 slides relative to the inner wall of the inflatable part 100 along its own length direction, the side wall of the shell 1 pushes the one-way valve opening key 210 to retract the air nozzle, so that the one-way valve 200 is in an open state, thereby making the air duct of the air nozzle of the inflatable part 100 open to achieve exhaust. At this time, if the dual-purpose air pump is in an open state, the air exhausted from the inflatable product enters the wind chamber from the air inlet 141, and is accelerated to be discharged from the exhaust port 1211 after being driven by the impeller 2, thereby improving the exhaust efficiency and achieving the air extraction function of the dual-purpose air pump.

[0065] In this embodiment of the present application, the housing 1 of the dual-purpose pump is in the shape of a long cylinder, so that the dual-purpose pump can be inserted into the inflatable part 100 of the inflatable product in both the forward and inverted states, and can simultaneously have the two functions of inflating and exhausting the inflatable product by adapting the opening and closing logic of the one-way valve 200 of the inflatable part 100; thus, the dual-purpose pump only needs to design one normal air path to complete the two functions of inflating and exhausting the inflatable product, effectively simplifying the overall structure of the air pump with the two functions of inflating and exhausting, and significantly reducing its production difficulty and production cost; At the same time, the installation operation of the dual-purpose pump on the inflatable product can be completed by simply inserting the dual-purpose pump into the corresponding inflatable piece 100 in a forward or inverted state, which effectively ensures the convenience of using the dual-purpose pump. In addition, after use, the dual-purpose pump can be withdrawn from the corresponding inflatable piece 100 at any time, which is convenient for maintenance and replacement, and can also be conveniently used with other inflatable pieces 100, effectively reducing the user's application cost and having strong practicality. At the same time, it can also continue to be stored inside the corresponding inflatable piece 100, which is convenient for next use, effectively improving the user experience.

The second side tube 131 is provided with a clamping edge 1311 at one end close to the first bracket 12, and a clamping groove 1212 is provided at one end of the first side tube 121 close to the second bracket 13. In actual production, the first bracket 12 and the second bracket 13 are coaxially arranged, and the clamping edge 1311 is embedded in the clamping groove 1212 along the axial direction of the shell 1 and fixedly engaged with the first side tube 121, so as to realize the fixed connection between the first bracket 12 and the second bracket 13. The air chamber is formed in the space surrounded by the first support plate 122, the second support plate 132 and the corresponding first side tube 121 and the second side tube 131, and the exhaust port 1211 is opened at one end of the first side tube 121 corresponding to the air chamber.

[0075] Of course, in the implementation manner of the present application, the first bracket 12 and the second bracket 13 can also be fixed by gluing, locking, ultrasonic welding and other process methods. This embodiment of the present application only specifically describes the snap-fit ​​fixing method, and no other specific description is given.

[0076] Reference Figure 5 and Figure 6 In this embodiment of the present application, the impeller 2 includes a wheel disc, a plurality of blades integrally formed on one axial side of the wheel disc, and a positioning convex ball 21 is formed in the middle of one end of the wheel disc axially away from the blades. Correspondingly, a limiting groove 1223 is provided on the first support plate 122 corresponding to the positioning convex ball 21. During assembly, the positioning convex ball 21 is embedded in the limiting groove 1223 along the height direction of the housing 1, and the output shaft of the motor penetrates the limiting groove 1223 and then extends into the positioning convex ball 21, and drives the positioning convex ball 21 to rotate around its own axis and cooperate with the inner wall of the limiting groove 1223. In addition, in this embodiment of the present application, after the positioning convex ball 21 is embedded in the limiting groove 1223, a ventilation gap exists between the wheel disc and the first support plate 122, and the ventilation gap is connected to the exhaust port 1211.

[0077] At the same time, refer to Figure 6 An annular through hole 1224 is formed on the first support plate 122 at the circumferential side of the limiting groove 1223, and the through hole 1224 penetrates the first support plate 122 along the axial direction of the shell 1, and the inner wall of the through hole 1224 is inclined from the center position of the first bracket 12 to the edge of the first bracket 12 along the first installation space toward the air chamber side; and, a plurality of air guide strips 1225 are provided on one side of the first support plate 122 located in the air chamber, and the plurality of air guide strips 1225 are arranged in a circular array around the axis of the shell 1.

[0078] After the motor is started, due to the rotation of the impeller 2, positive pressure is formed at the exhaust hole, and the heat generated by the battery 5 and the motor in the first installation space are discharged from the shell 1 from the installation sleeve 1222, the through hole 1224, the ventilation gap, and the exhaust port 1211 in sequence, which is beneficial to the heat dissipation of the battery 5 and the motor in the first installation space, thereby reducing the probability of damage to the dual-purpose pump due to overheating during use, effectively improving the safety of the dual-purpose pump, extending its service life, and further reducing its use cost.

[0079] Reference Figure 3 and Figure 4 The top cover 14 is detachably mounted on the second side tube 131 at one end of the second support plate 132 away from the first bracket 12; a second installation space is formed between the top cover 14 and the second support plate 132. Specifically, the circuit module 4 includes a circuit board, which is installed in the second installation space.

[0080] In this embodiment of the present application, screws may be provided to sequentially penetrate the top cover 14, the circuit board and the second support plate 132 along the axial direction of the housing 1, so as to realize the detachable installation of the circuit board between the top cover 14 and the second support 13. Of course, the stable installation of the three may also be realized by adhesive fixation, structural clamping, etc., and the implementation method of the present application does not impose specific restrictions on this.

[0081] Furthermore, the side walls of the first bracket 12 and the second bracket 13 are provided with wire passing holes. During actual production, the connecting wires of the motor and the battery 5 pass through the wire passing holes on the side walls of the first bracket 12 and the second bracket 13 respectively and are welded to the circuit board, thereby realizing the layout of the circuits in the dual-purpose air pump. The circuit layout structure is simple and the assembly operation is convenient, which helps to further improve the production convenience of the dual-purpose air pump.

[0082] Reference Figure 1 and Figure 4 The air inlet 141 passes through the top cover 14 and the second installation space in sequence along the axial direction of the housing 1 until it is connected to the air chamber; in addition, referring to Figure 5 A plurality of air outlets 6 are provided around the axis of the housing 1 at the position corresponding to the second installation space on the second side pipe 131. After the pump is started, the air in the environment enters the air chamber through the air inlet 141, passes through the second installation space, and is discharged from the housing 1 from the corresponding air outlet 6, thereby taking away the heat generated by the operation of the electronic components on the circuit board, which is beneficial to the heat dissipation of the second installation space, thereby further improving the safety of the pump and extend its service life.

[0083] Below, the present application is further elaborated in conjunction with the inflatable parts of the inflatable product. In one embodiment, an air pump assembly is provided, which includes the dual-purpose air pump for pumping and charging described in any of the above embodiments, and also includes an inflatable part 100. Specifically, in this embodiment of the present application, the inflatable part 100 is a cylindrical structure with one end open, and any radial side wall thereof is provided with an air nozzle for connecting the inner cavity of the inflatable part 100 with the inner cavity of the inflatable product, and the air nozzle as a whole is a cylindrical structure with two ends open. In addition, a one-way valve 200 structure is provided in the air nozzle, wherein the valve sheet of the one-way valve 200 is attached to the end of the air nozzle extending into the inner cavity of the inflatable product, and the one-way valve opening key 210 extends from the air nozzle into the inner cavity of the inflatable part 100 along the length direction of the air nozzle.

[0084] In actual application, when performing inflation operation, the pump is inserted into the corresponding inflatable part 100 in a forward state until the one-way valve opening key 210 is embedded in the avoidance groove; at this time, the pump is started, and the driving component 3 drives the impeller 2 to rotate, so that the air in the environment enters the wind chamber from the air intake 141, and is discharged from the exhaust port 1211 after being driven by the impeller 2. At this time, positive pressure is generated at the exhaust port 1211, thereby pushing the valve plate of the one-way valve 200 in the inflatable part 100 to open, and air is continuously filled into the inner cavity of the corresponding inflatable product, thereby realizing the inflation process of the pump.

[0085] When the shell 1 slides relative to the inner wall of the inflatable part 100 along its own length direction and keeps one end of the air inlet 141 facing inward, the pump is inserted into the corresponding inflatable part 100 in an inverted state. Since the side wall of the shell 1 slides relative to the inner wall of the inflatable part 100 along its own length direction, the side wall of the shell 1 pushes the one-way valve opening key 210 to retract the air nozzle, so that the one-way valve 200 is in an open state, and then the air duct of the air nozzle of the inflatable part 100 is connected to connect the inner cavity of the inflatable product with the inner cavity of the inflatable part 100 to achieve exhaust. At this time, if the pump is in an open state, the air exhausted from the inflatable product enters the wind chamber from the air inlet 141, and is accelerated and discharged from the exhaust port 1211 after being driven by the impeller 2, so that the exhaust function of the pump can be achieved.

[0086] In this way, the two functions of inflation and exhaustion of the air pump can be achieved simultaneously through only one normal air path, which effectively simplifies the overall structure of the dual-purpose air pump for inflation and exhaust, and reduces its production difficulty and production cost; at the same time, it is easy to use and maintain, and has a long service life; and the user can keep it built into the inflatable part 100 or take it out from the inflatable part 100 according to actual needs, which effectively saves user costs and improves user experience.

[0087] It should be noted that the above embodiments can be freely combined as needed. The above is only the preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present application, and these improvements and modifications should also be regarded as the protection scope of the present application.
