Description

Technical Field

[0001] This utility model relates to the field of handheld bidet technology, and in particular to an air intake structure for a handheld bidet. Background Technology

[0002] Existing handheld bidets typically include a housing, a nozzle, a water pump, a battery, and a connector. The nozzle, water pump, battery, and connector are all housed within the inner cavity of the housing. The connector is fitted inside the bottom of the housing, or it may protrude from the bottom of the housing and connect to it. The connector connects to a water reservoir and includes an air inlet check valve and a charging socket. The air inlet check valve controls the unidirectional entry of outside air into the water reservoir during water extraction by the water pump, thus balancing the air pressure inside the reservoir. The charging socket is used to charge the battery. The side wall of the housing has an air inlet connected to the air inlet check valve and a charging port corresponding to the charging socket.

[0003] However, in some existing technologies, the charging port of the bidet is directly used as the air inlet. This means that the charging port cannot be completely sealed during normal cleaning and use, otherwise air cannot enter, resulting in poor waterproof and dustproof performance for the charging port. In other existing technologies, the openings of the air inlet and the charging port are both set towards the radial direction of the outer shell. That is to say, there is an angle between the axis of the air inlet and the axis of the charging port. In this way, the air inlet and the charging port need to be formed with different mold cores during molding, which makes the molding more complex. Moreover, the air inlet is generally designed to be smaller, and its mold core is thinner. The maintenance cost of the separately set air inlet mold core is also higher.

[0004] In view of this, how to ensure the waterproof and dustproof effect of the charging port, while facilitating the molding of the air inlet and charging port of the bidet, so as to make the molding mold structure simple and the maintenance cost low, is a technical problem to be solved in this field. Utility Model Content

[0005] To solve the above-mentioned technical problems, the purpose of this utility model is to provide an air intake structure for a handheld bidet that can ensure the waterproof and dustproof effect of the charging port, and also make the mold core for forming the air inlet and charging port simpler and the maintenance cost lower.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A handheld bidet's suction structure includes a housing, a nozzle, a water pump, a battery, and a connector. The nozzle is located on the top of the housing. The water pump, battery, and connector are all located within the inner cavity of the housing. The connector is fitted inside the bottom of the housing and has an internal thread for connecting to a water reservoir. The connector has an air inlet valve and a charging socket. The side wall of the housing has an air inlet connected to the air inlet valve and a charging port corresponding to the charging socket. The air inlet and the charging port are spaced apart and face the same direction.

[0008] In some preferred embodiments, the connecting seat is provided with an outwardly open air intake chamber, and the one-way air intake valve and the air intake port are both connected to the air intake chamber.

[0009] In some preferred embodiments, the connecting seat is provided with an upper cavity, a middle cavity and a lower cavity from top to bottom. The upper cavity is connected to a bracket, and the water pump and battery are mounted on the bracket. The middle cavity includes a charging cavity and an air inlet cavity separated from each other. The charging cavity is used to install the charging socket. The lower cavity is used to accommodate the opening of the water storage device. The inner wall of the lower cavity is provided with the internal thread.

[0010] In some preferred embodiments, the bracket is integrally formed with the connector, and a circuit board is also mounted on the bracket. The circuit board is electrically connected to the water pump, the battery, and the charging socket, respectively.

[0011] In some preferred embodiments, an air intake gap is formed between the inner wall of the housing and the outer wall of the connecting seat, and the air intake port is connected to the air intake cavity through the air intake gap.

[0012] In some preferred embodiments, the air inlet is positioned close to the charging port.

[0013] In some preferred embodiments, a sealing groove is provided on the outer wall of the connector above the air inlet and the charging port, and a sealing ring is provided in the sealing groove. The outer wall of the connector forms a sealing fit with the inner wall of the housing through the sealing ring.

[0014] In some preferred embodiments, the connecting seat is provided with a water baffle plate, which is located at the top of the internal thread. When the internal thread is engaged with the external thread of the opening of the water reservoir, the water baffle plate closes the opening of the water reservoir. The water baffle plate is provided with the air inlet check valve and a water inlet. The water pump draws water from the water reservoir through the water inlet and sprays it out of the nozzle.

[0015] In some preferred embodiments, the intake check valve is a duckbill valve.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] This invention separates the air inlet and charging port, ensuring the charging port is completely sealed when not charging, thus guaranteeing waterproof and dustproof protection. Furthermore, the air inlet and charging port face the same direction, meaning their centerlines are parallel. This allows the same mold core to be used for both the air inlet and charging port on the molded housing, simplifying the mold core and reducing maintenance costs. Attached Figure Description

[0039] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0040] Please see Figures 1 to 7 The present invention provides a preferred embodiment of a handheld bidet's suction structure, comprising a housing 10, a nozzle 20, a water pump 30, a battery 40, and a connecting seat 50. The nozzle 20 is located at the top of the housing 10. The water pump 30, battery 40, and connecting seat 50 are all located within the inner cavity of the housing 10. The connecting seat 50 is fitted inside the bottom of the housing 10 and has an internal thread 51 for connecting to a water reservoir (not shown). The handheld bidet is connected to the water reservoir via the connecting seat 50. The connecting seat 50 is equipped with an air inlet one-way valve 60 and a charging socket 70. The air inlet one-way valve 60 controls the unidirectional entry of outside air into the water reservoir during the process of the water pump 30 drawing water from the reservoir to balance the air pressure inside the reservoir. The charging socket 70 is used to charge the battery 40. The side wall of the housing 10 has an air inlet 11 connected to the air inlet one-way valve 60 and a charging port 12 corresponding to the charging socket 70.

[0041] The main improvement of this invention is that the air inlet 11 and the charging port 12 are separated and their orientations are the same. This separation, compared to existing designs where the charging port is directly used as the air inlet, means that the charging port 12 is not used for air intake. In non-charging states (e.g., normal cleaning), it can be completely sealed, ensuring waterproof and dustproof protection for the charging port 12. Furthermore, the orientations of the air inlet 11 and the charging port 12 are aligned, meaning that the axis X1 of the air inlet 11 and the axis X2 of the charging port 12 are parallel (e.g., ...). Figure 7 As shown, when molding the air inlet 11 and the charging port 12 on the outer shell 10, the same mold core can be used. The air inlet 11 and the charging port 12 can be molded simultaneously by pulling the mold core in the same direction, which makes the mold core simpler and the maintenance cost lower.

[0042] In this embodiment, the connecting seat 50 is provided with an outwardly open air intake chamber 52, and the air intake one-way valve 60 and the air intake port 11 are both connected to the air intake chamber 52. Furthermore, an air intake gap 13 is formed between the inner wall of the outer casing 10 and the outer wall of the connecting seat 50, and the air intake port 11 is connected to the air intake chamber 52 through the air intake gap 13. See also Figure 6 As shown by the dotted line with arrows, during the process of water pump 30 drawing water from the water storage tank, outside air can sequentially enter the water storage tank through air inlet 11, air inlet gap 13, air inlet chamber 52, and air inlet one-way valve 60 to balance the air pressure inside the water storage tank. By setting air inlet chamber 52 and air inlet gap 13, the position of air inlet 11 can be set more flexibly, that is, air inlet 11 can be flexibly adjusted according to the setting position of charging port 12.

[0043] In this embodiment, the connecting seat 50 is provided with an upper cavity 55, a middle cavity 56 and a lower cavity 57 from top to bottom. The upper cavity 55 is connected to a bracket 80, and the water pump 30 and the battery 40 are installed on the bracket 80. The middle cavity 56 includes a charging cavity 58 and an air inlet cavity 52 that are separated from each other. The charging cavity 58 is used to install the charging socket 70. The lower cavity 57 is used to accommodate the opening of the water storage device. The inner wall of the lower cavity 57 is provided with an internal thread 51.

[0044] In this embodiment, the bracket 80 and the connecting seat 50 are integrally formed. A circuit board 90 is also mounted on the bracket 80, and the circuit board 90 is electrically connected to the water pump 30, the battery 40, and the charging socket 70, respectively. The integral formation of the bracket 80 and the connecting seat 50 makes assembly simpler and the structure more compact.

[0045] In this embodiment, the air inlet 11 is positioned close to the charging port 12. This arrangement allows for a smaller volume of the shared mold core for forming the air inlet 11 and the charging port 12.

[0046] In this embodiment, a sealing groove 53 is provided on the outer wall of the connector 50 above the air inlet 11 and the charging port 12. The sealing groove 53 is provided with a sealing ring 531. The outer wall of the connector 50 forms a sealing fit with the inner wall of the outer shell 10 through the sealing ring 531.

[0047] In this embodiment, the connecting seat 50 is provided with a water-blocking plate 54, which is located at the top of the internal thread 51. When the internal thread 51 is engaged with the external thread of the water reservoir opening, the water-blocking plate 54 closes the opening of the water reservoir. The water-blocking plate 54 is provided with an air inlet check valve 60 and a water inlet 541. The water pump 30 draws water from the water reservoir through the water inlet 541 and sprays it out of the nozzle 20.

[0048] Specifically, in this embodiment, the intake check valve 60 is a duckbill valve. Of course, it is understood that the intake check valve 60 can also adopt a known existing check valve structure, as long as it can allow outside air to enter the water storage tank in one direction from the outside to the inside.

[0049] In this embodiment, in order to prevent water or dust from entering the charging port 12, a detachable sealing cover 121 is also provided on the charging port 12.

[0050] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
