Description

Technical Field

[0001] The invention relates to the field of automobile washing pumps, and in particular to a washing pump with waterproof function and a vehicle. Background Art

[0002] In the car washing system, the washer pump and the washer pot are important components to ensure the cleanliness of the windshield. Usually, the washer pump and the washer pot are arranged at a lower position in the vehicle to optimize the space layout and liquid flow path. However, this arrangement also brings certain technical challenges in some cases.

[0003] The body of the washing pump usually needs to be provided with a vent to ensure the heat dissipation of the motor and prevent the performance of the pump from being degraded or damaged due to high temperature. The vent of the washing pump currently designed is a vent with a parallel straight-out design on both sides of the washing pump, and the vent is connected to the internal motor. However, this design also makes the washing pump vulnerable to the influence of the external environment, especially in the case of wading driving. During the driving process of the vehicle, the water flow may enter the washing pump through the vent, causing the internal parts of the pump (motor, pump housing assembly, etc.) to contact with water and rust, resulting in high current of the water pump, no water spraying, or rust and blockage of the motor, which seriously affects the operating efficiency of the pump and may eventually make the entire washing system unable to work normally. Therefore, how to effectively prevent water intrusion and protect the washing pump from environmental factors has become an important issue in the design of washing pumps. In the prior art, a one-way breathable membrane can be added to the existing vent with a parallel straight-out design, but this will not only increase the cost and investment, but also reduce the air permeability inside the washing pump. Summary of the invention

[0004] In view of the defects in the prior art, the purpose of the present invention is to provide a washing pump and a vehicle with a waterproof function. By optimizing the outer casing of the washing pump and setting the air permeable channel downward, the length of the channel is extended. Under the action of internal and external pressures, external water is less likely to invade, thereby extending the service life and avoiding rust and failure of the internal motor of the washing pump.

[0005] In order to achieve the above technical effects, the present invention adopts the following technical solutions:

[0006] According to a first aspect of the present invention, there is provided a washing pump with a waterproof function, comprising an upper cover, a pump casing and a motor component, wherein the pump casing is sleeved on the outside of the upper cover to form a pump chamber therewith, the motor component is arranged in the pump chamber, and the pump casing is provided with symmetrical air holes which are in communication with the pump chamber, and the air hole portion of the pump casing is provided with a baffle portion and an outer shell portion, the baffle portion having a preset length and being able to extend into the pump chamber, thereby forming a downward narrow air passage between the baffle portion and the outer shell portion, and when the vehicle is wading, external water is blocked by the baffle portion and cannot enter the pump chamber.

[0007] According to a second aspect of the present invention, there is provided a vehicle, comprising the above-mentioned washer pump with waterproof function.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] The washing pump with waterproof function provided by the present invention optimizes the washing pump shell, sets the air permeable channel downward, and extends the length of the channel. With this design, on the one hand, under the action of internal and external pressures, external water is less likely to invade, thereby protecting the internal parts of the washing pump motor from rust, extending the service life, and avoiding early failure of the washing pump. On the other hand, it will not reduce the heat dissipation and air permeability of the washing pump. At the same time, with this design, there is no need to make major changes to the washing pump or add other devices, thereby avoiding the increase of cost and investment.

Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0015] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

Therefore, once an item is defined in one figure, it does not need to be further defined and explained in the subsequent figures. In addition, all directional indications in this application (such as up, down, left, right, front, back, bottom...) are only used to explain the relative position relationship, movement, etc. between the components under a certain specific posture (as shown in the figures). If the specific posture changes, the directional indication will also change accordingly. Furthermore, the descriptions involving "first", "second", etc. in the application are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated.

[0017] First Embodiment

[0018] This embodiment provides a washing pump with a waterproof function, such as Figures 1 to 3 As shown, the washing pump includes an upper cover 1, a pump casing 2, a motor component, a sealing assembly and an impeller; wherein the pump casing 2 is sleeved on the outside of the upper cover 1 to form a pump cavity therewith, the motor component is arranged in the pump cavity, and the pump casing is provided with air holes 3 which are symmetrically connected to the pump cavity, so as to effectively discharge the heat and pressure of the motor component.

[0019] like Figure 1 As shown, this embodiment optimizes the structure of the air vent 3 of the pump casing on the washing pump, sets the air vent 3 to face downward, and extends the length of the hole. Under the action of internal and external pressures, external water is less likely to invade, achieving IPX4 waterproof grade, thereby protecting the pump motor components from rust, extending the service life, and avoiding early failure.

[0020] Specifically, Figure 1 As shown, the air vent of the pump housing of the washing pump with waterproof function is provided with a baffle portion 4 and an outer shell portion 5. The baffle portion 4 has a certain length and extends into the pump cavity, thereby forming a downward narrow air vent between the baffle portion 4 and the outer shell portion 5. When the vehicle wades, the external water is blocked by the baffle portion 4 and cannot enter the pump cavity. The design of the air vent 3, on the one hand, will not affect the air permeability of the washing pump, and on the other hand, it also solves the problem of external water easily penetrating into the pump cavity. At the same time, there is no need to make major changes to the structure of the washing pump or add other devices to achieve this function, avoiding the increase of cost and investment.

[0021] In the prior art, if a vehicle wades through water, when the water level reaches the orifice, the water will directly pass through the orifice. Figure 2The parallel straight-out design of the air vent enters the pump chamber. If the air vent 3 adopts the design of the present embodiment, when the water level reaches the orifice position, due to the obstruction of the baffle portion 4, the water will first enter the narrow air vent between the baffle portion 4 and the outer shell portion 5, rather than invading the pump chamber all at once, thereby avoiding rust and failure of the internal motor components due to water seepage.

[0022] Second Embodiment

[0023] This embodiment provides a vehicle, including the washer pump with waterproof function described in the first embodiment.

[0024] The above describes the specific embodiments of the present invention. Based on the above description, relevant personnel can make various changes and modifications without departing from the technical concept of the present invention.
